The square tube comprises an upper square tube body and a lower square tube body. The connecting assembly comprises an upper jacking base, a lower jacking base, an upper baffle and a lower baffle, and a threaded rod is installed between the upper jacking base and the lower jacking base. The lower square tube body is fixedly installed on the stand column. The large arms are connected through a 304 stainless steel double chain. The lower end of the fixing plate is fixedly installed on the lower square tube body, and the rear end of the fixing plate is fixedly installed on the upper square tube body. Rotating shafts are arranged at the two ends of the winding rod and installed at the front end of the fixing plate. The clamping rod is installed at the foremost ends of the large arms. The maximum span of the large-span awning is 20 m, and the large awning can stretch out by 5 m; the large-span awning is light, high in wind resistance, free of rusting and color fading, attractive in use and long in service life; because the double square tube bodies form the fixing square tube, the suction firmness of the telescopic awning is greatly improved, and the large-span awning is suitable for outdoor places with a large sun-shading area. In yet another prior art Chinese patent application CN2321854 titled “Multi function window awning for sunshading and rain-proof’ discloses a multifunction window awning for sunshading and rain-proof. The load-bearing framework of the window awning is composed of a front beam and a back beam which are made of angle steel and is also composed of a longitudinal support arm whose one end is glidingly connected in 123 with the front beam and the other is hinged on the side wall of a window. A transparent rain-proof cloth is connected with the upper part of the load-bearing framework, and a foldable sunshading device is connected with the lower part of the load-bearing framework through the sliding rail which is connected with the front beam and the back beam. A suspension curtain device which can shade direct sunlight is connected to the longitudinal support arm, and the suspecion curtain device not only has big horizontal sunshading area but also can vertically shade direct sunlight and effectively ensure the indoor lighting and ventilation. The utility model has flexible and reliable operation, strong wind resistance, convenient packaging, carrying and self assembly and long service life.

It is further another prior art US patent application US 5225748 titled“Method or apparatus for controlling and monitoring the position of an awning or similar facility” discloses the utilization period of the awning be increased in connection with automatic or manual control means in that the awning is preferably incrementally retracted as a function of the magnitude of the wind velocity, as determined through measurement, with the wind velocity being determined in corresponding graduations, and, as a function thereof, in that the control unit for the awning drive motor moves the awning to intermediate awning positions which have priority over all other control influences. In addition to the limit switches, which are present anyway and which indicate the "fully retracted' or "fully extended' positions, a plurality of intermediate sensors, corresponding to the number of desired increments, are disposed to determine the intermediate positions, with the signals output by the intermediate sensors, which indicate the actual position of the awning being compared with wind-velocity-determined awning set point position signals.

The present invention has overcome the drawbacks in the prior art wherein the present invention withstands wind pressure, rain and provide rain water drain system in outdoor area such as stadium/arena etc.

As illustrated in figure 1, figure la and figure lb, the said rain sensing blades (115) are fastened electronically and the said sensor electrodes generates pulse which is further captured by the said driver module connected to the rod (not shown in diagram). Furthermore, the said control unit (110) is a processor which controls and monitors said units by means of control logic.

The said pole lighting setup (130) as further illustrated in figure 1 and figure 1A comprises of plurality of poles (135) to provide lighting to the said outdoor area, thereby the said lighting is automatically switched on/off by means of the said controller. The light poles (135) comprises of belt (145) that runs on the said guided rollers (140) to provide stability and maneuverability.

The lean frames (170) of the reel hook assembly (160) are placed at four corners of the outdoor area and are further connected to a lean frame (170) thereby providing stability to the reel hook assembly. The lean frame (170) comprises of the said smooth circumferential hole (175) to provide upward and downward movement of reel hook. Moreover, the reel hook assembly (160) comprises of a power unit (185) which is a 12 Volt DC motor or more, which is controlled by means of a motor driver which is further connected to a controller.

The said gas pumping unit (180) also comprises of power unit (185) which is a 12 Volt DC motor or more, connected to an air compressor setup (220). The said gas pumping unit (180) is controlled by means of control unit (110), thereby activating the gas pumping unit (180) by means of said control unit (110).

The inner circle segment (195) of the transparent bubble sheet cover receives gas by means of gas hose, thereby raising the sheet off the ground thereby providing uniform sideward expansion and unilaterally covering the top of the outdoor area as illustrated in figure 1A.

The wind shield unit (205) moves by means of the said belt (215) which is moved by means of DC 12 Volt motor or more, placed at the light poles (135). The said motor is further connected to the said driver unit (not shown in diagram) to provide front and back movement of the said windshield unit (205) by means of signal from said controller unit pertaining to wind directional flow. The said wind shield unit is a 360° rotating foldable unit.

Furthermore, the rain sensors are mounted on the top circumference of the outdoor area and the number of sensors depends on the requirements of the area to be sensed. The rain sensor further sends signal to the controller which thereby activates the reeling hook to reel down. The controller gives alarm to spread the bubble sheet. The centre of the hooker setup is connected to the helium/hydrogen bubble sheet. The motor in the reel hook assembly drives the reel hook upwards along with the bubble sheet. Moreover, the rain sensing blades are telescopic blades on the circumference of the outdoor area.

The bubble sheet (155) is filled with helium/hydrogen gas with a diameter of 40 meters and height of 6 meters in the inner circle segment (195) and gradually thinning to the end forming the outer circle segment (200) thereby aiding the bubble sheet (155) to move upward and cover the entire outdoor area. The inner circle segment (195) is connected with gas tubes (190) which provide means to fill gas in the inner circle segment (195). The pole lights (130) of the outdoor area are lit automatically by means of rain sensor thereby providing proper illumination. The pole is erected on the circumference with equal distance and the pole height is not less than 80 meters. Moreover, in another embodiment additional temporary poles are erected in the outer circumference by providing a slot on the ground to erect the poles prior to commencement of game based on the weather forecast.

Furthermore, the wind shield has a circumference covering 180 meters breadth as per the gap between stadium roof and top of the flood lights, which includes around 24 wind blades each of size 7.5 meters width and height of 15 meters each (this height is altered according to the gap between the stadium roof and top of the flood lights.

The present invention will manage wind pressure and thereby prevent any challenges in outdoor games played in stadium. The present invention also helps to drain water out of the ground safely. The transparent and inflatable sheet is used with less glare.
