The flowing water in the valley has a certain fall, the fall is like a dam, and float-type plungers are constructed on two sides of the dam. The device consists of a pump body, a plunger, a ventilation bin, an electromagnetic valve, an ascending floater and other parts. The specific working process is that the electromagnetic valve of the ventilation bin closes the outlet of the ventilation bin and opens the inlet, and the space liquid in the plunger is replaced with the air in the ventilation bin. When the ventilation bin is full of liquid, the inner floater in the ventilation bin pulls open the clamp spring under the action of buoyancy, and the ventilation bin switch returns to the original state of closing the inlet and opening the outlet under the action of the spring. At the moment, the liquid in the ventilation bin flows out and is discharged into the box body through the guide pipe, the floater in the box body generates buoyancy to pull the plunger, and the plunger completes an upward stroke under the combined action of the buoyancy and the lifting force. When the plunger reaches the top dead center, the pump body air outlet and the plunger air outlet are opened, air is exhausted from the pump body and the plunger, and the plunger which is completely filled with liquid is prepared for descending. When the plunger starts to move downwards, the exhaust port of the pump body is closed, the exhaust port of the plunger is still opened, and liquid enters the pump body from the plunger. When the plunger approaches the lower extreme point, the exhaust port of the plunger enters the control tube, and when the plunger reaches the lower extreme point, the control tube opens the clamp spring, and the exhaust port of the plunger is closed.

The liquid level difference control port is a facility for directly supplementing water for the lifting box by using the liquid level difference manufactured by the dam while ensuring the liquid level difference at two sides of the dam. If the equipment of the same specification has special requirements on the displacement or the lift, the water quantity replaced by the plunger cannot meet the lifting requirements, water can be supplied through the liquid level difference control port, and the lifting box floater can obtain more lifting force. The liquid level difference control port can transmit power to the quick opening and closing device through the arranged impeller while controlling the liquid level difference on the two sides of the dam within a certain range, the liquid levels on the two sides of the dam objectively exist two states, one state is that potential energy generated by the liquid level difference on the two sides of the dam is enough to open the switch of the ventilation bin, and the electromagnetic valve does not work; and the second is that when potential energy generated by liquid level difference at two sides of the dam is not enough to open the switch of the ventilation bin, the electromagnetic valve assists in working, and the output is supplemented to ensure that the switch works normally.
The linkage control valve is fixed by a positioning spring of the ventilation bin in an initial state that an exhaust port of the ventilation bin is closed and a water outlet is opened, the linkage control valve moves downwards under the action of external force (an electromagnetic valve), the water outlet is closed, when an exhaust port switch is opened, the linkage rod moves downwards, a valve plate of the water outlet extrudes a wedge-shaped fixture block connected with a clamp spring, the wedge-shaped fixture block is clamped at the bottom of the wedge-shaped fixture block under the action of the clamp spring, air in the ventilation bin is replaced with liquid in the plunger, and the liquid level in the. When liquid in the ventilation bin rises to a high point, the buoyancy of a floater in the ventilation bin pulls the transmission lever and extrudes the clamp spring, the clamp spring pushes the top end of the clamping block to enable the wedge-shaped clamping block to rotate, and the lower valve plate rises to open the water outlet; the linkage control valve is switched back to the initial position, and the liquid in the ventilation bin is discharged into the water tank and the lifting box through the water outlet. When the quick opening and closing device is in an initial state, the ratchet wheel is clamped on the pawl, when the external force pulls the winding and power storage spring to a certain degree, the pawl is released, and the ratchet wheel pushes the shifting plate at the bottom of the linkage rod to open the linkage control valve; when the power spring loses elasticity, the ratchet wheel restores to the initial state and is ready for the next stroke.
The plunger meets certain self weight required by descending, the weight is based on overcoming friction force and meeting descending speed, the determined weight is a constant value in the plunger pump with the same specification, if the displacement is required to be increased to finish larger stroke, the plunger is required to be lengthened, the self weight of the lengthened part can be offset by a mode of additionally installing a balance floater inside, and the constant weight is not changed when the plunger moves. Therefore, in theory the plunger can increase the stroke infinitely over the liquid height range, while the power consumed and the amount of liquid and air that needs to be replaced are unchanged. The lifting box is easy to obtain liquid due to the lower position of the lifting box body, and keeps synchronous operation with the plunger.
The sealing box body of the embodiment relates to moving parts, and sealing is realized in a dynamic sealing mode. The various types of gas switches, liquid switches and solenoid valves involved in this embodiment are preferably gas spring switch valves, liquid spring switch valves and solenoid valves produced by zhejiang south high automatic valve, qiagbaga valve manufacturing, tianjin high medium pressure valve manufacturing, funingn county xin shenyuan valve manufacturing, shenzhen zeng fran fluid machinery equipment, qian jubo valve, guanzhou guan valve, shanghai shuangtai valve, zhejiang jinhao valve, and shanghai ruitz valve manufacturing. In order to save design and research cost, various switch valves in the embodiment can be replaced by switch valves with the same functions produced by the companies; or use of an existing on-off valve in the pneumatic and hydraulic fields.
