FIELD OF INNOVATION

The present innovation relates to a device for water sampling. More particularly, the device is used in monitoring water quality especially in aquaculture.

BACKGROUND OF THE INNOVATION

In aquaculture, the optimum water quality is essential to maintain the good ecosystem for aquatic species including fishes. If the water quality of a culture system is poor, the aquatic species can suffer from health problems such as damage and diseases. There are tools and test kits used to test water-quality parameters such as the level of dissolved oxygen, pH, alkalinity, water hardness, ammonia levels and many more. In order to obtain accurate result for the test, the efficient water sampling device is very important. The sampling process usually not a one time process and the quality of the water has to be monitored frequently.

Conventionally, the big size of the water sampler needs a big space for keeping process. Other than that, the big feature of the existing water sampler is inconvenient for the collector especially for those who want to take outdoor samples such as from the sea or river or lake whereby the collector need to use boat to go to the desired area. The simplest equipment and device is needed to avoid tripping hazard during water sampling. Besides that, the complicated features of existing water sampler in the market need only the expert to handle it and the sampling process takes more time until it is done. Constantly monitoring the water quality must be done based on the individual's knowledge and competence with the device. Because of the lack of knowledge and competence with the device, the breeders had to spend a lot of money to support the costs of monitoring culture water quality. Water sampling must be done manually for the purpose of monitoring with unregulated and constantly because lack of knowledge and incompetence with the device. This will contributes to a deterioration of water quality and threatening culture. Due to incompetence with the device during sampling process, it will drag the time too long and low accuracy sample. It also contributes an error for final sample analysis.

Other than that, the horizontal configuration of the sampling device existing in the market is not convenient in order to obtain an accurate result for the water quality test especially in rapid flow of water sample area. The horizontal device will turning around and make the sampling process more difficult. Usually, when the horizontal configuration device is used, the first area of water sampling which is the water surface enters the sampling device and the water surface will remained in the device eventhough the device is dipped into the bottom or desired area and caused the exact water samples needed is inaccurately obtained. The horizontal configuration also make the sampling process is difficult in a limited space of sampling area for example in tube well.

Thus, there is a need in the art to provide a user-friendly device for water sampling that is small in size, light in weight and most important thing is to give an accurate result for each test.

SUMMARY OF THE INNOVATION

According to a first aspect of the present innovation, there is provided a water sampling device comprising: a hollow cylindrical container (100) having two open end; a holder ( 102) is attached at a surface of the hollow cylindrical container ( 100) for holding the hollow cylindrical container (100); a ring (104) is tied by a connector (106) at an upper side of the hollow cylindrical container ( 100); an upper valve (108) and a lower valve ( 1 10) are connected each other by a cord (1 12) and were placed inside the hollow cylindrical container (100), the upper valve (108) is on top and the lower valve (1 10) is at bottom of the hollow cylindrical container (100) wherein the upper valve ( 108) and lower valve (1 10) is a one way valve, the cord (1 12) is extended from the upper valve ( 108) and out of the hollow cylindrical container (100) and linked to the holder (102); and a strand (200) with a hook (202) at one end wherein the hook (202) is removably engaged to the ring ( 104) for holding and drive the hollow cylindrical container ( 100) to a desired depth . The provision of the device is advantageously as it results in observing the quality of the desired water.

Advantageously, the features of the present innovation are user-friendly whereby not only an expert can handle the device.

Advantageously, the device is used to minimize the time consumption during the water sampling process. Advantageously, the device is dipped vertically into the water to avoid the desired water samples mixing with other particles or undesired water that may caused error or inaccurate results.

The present innovation relates to a water sampling device comprising: a hollow cylindrical container ( 100) having two open end; a holder (102) is attached at a surface of the hollow cylindrical container (100) for holding the hollow cylindrical container ( 100); a ring (104) is tied by a connector ( 106) at an upper side of the hollow cylindrical container (100); an upper valve ( 108) and a lower valve ( 1 10) are connected each other by a cord ( 1 12) and were placed inside the hollow cylindrical container ( 100), the upper valve ( 108) is on top and the lower valve (1 10) is at bottom of the hollow cylindrical container ( 100) wherein the upper valve ( 108) and lower valve ( 1 10) is a one way valve, the cord ( 1 12) is extended from the upper valve (108) and out of the hollow cylindrical container ( 100) and linked to the holder (102); and a strand (200) with a hook (202) at one end wherein the hook (202) is removably engaged to the ring ( 104) for holding and drive the hollow cylindrical container ( 100) to a desired depth. The device can be clearly seen as illustrated in FIG.l

In one embodiment, the sampling device is covered by a cylindrical casing (300) as illustrated in FIG.2 and FIG.3. During the water sampling process, the device is vertically dipped into the water with the help of a strand (200) to a desired depth. The strand is preferably a long rope or a cable whereby the length is depending on the desired depth of the desired water sample. A thin plate-shape of the lower and upper valve ( 108, 1 10) is automatically open once the device is dipped into the water to allow the water enters from the lower valve ( 1 10) towards the upper valve ( 108) and passes through the hollow cylindrical container (100). The hollow cylindrical container ( 100) is preferably made from synthetic plastic polymer or polyvinyl chloride (PVC) with 500ml capacity. When the device reached to the desired depth, the lower and upper valve (108, 1 10) will automatically closed and the desired water is trapped inside the hollow cylindrical container (100). The valve is a one-way valve that normally allows the water to flow through the hollow cylindrical container (100) in only one direction. The device is then pulled up and water sample is taken. Once the water sample is collected, the water may be drained from the cylindrical container by pulling the extended cord for water quality testing process. Although the innovation has been described with reference to particular embodiment, it is to be understood that the embodiment is merely illustrative of the principles and applications of the present invention. It is therefore to be understood that numerous modifications may be made to the illustrative embodiment that other arrangements may be devised without departing from the scope of the present innovation as defined by the appended claim.
