Title:
LEVER-TYPE UNPOWERED RELAY WELL
Document Type and Number:
WIPO Patent Application WO/2023/208038
Kind Code:
A1
Abstract:
Disclosed in the present application is a lever-type unpowered relay well, comprising a water intake device and a water output device, which are located on two sides of the relay well. A normal pressure air pipe and a negative pressure air pipe are arranged on the relay well; a lever structure is arranged between the normal pressure air pipe and the negative pressure air pipe; a rotating structure is arranged above the lever structure; and a floating ball structure is arranged on a side of the rotating structure. The lever structure comprises a lever left rod and a lever right rod, wherein a left plug, a lever weight, a lever hinge, a lever right rod and a right plug are arranged on the lever left rod and the lever right rod in sequence. The rotating structure comprises a left-rotating rod, a right-rotating rod, a right axial pressing rod, a rotating lever hinge, a left axial pressing rod and a rotating lever weight. The floating ball structure comprises a floating ball, a floating ball long rod, a floating ball hinge, a floating ball short rod and a floating ball short rod pressing rod. By means of the relay well, the function of "instantly opening a normal pressure suction port and closing a negative pressure suction port" at a high liquid level and "instantly closing the normal pressure suction port and opening the negative pressure suction port" at a low liquid level can be realized, thereby realizing a function of transmitting sewage without depending on electric energy.
