Description

Technical Field

[0001] This utility model relates to a grid separation device for preventing garbage blockage at a reservoir drainage outlet, belonging to the technical field of grid separation devices. Background Technology

[0002] A reservoir is an artificial lake formed by building a dam at the narrowest point of a mountain valley or river. It is a type of water conservancy project, mainly composed of a dam, spillway, and water release structures. Reservoir outlets are usually equipped with grates to intercept and separate large debris, protect aquatic life, ensure water quality, and facilitate cleaning and maintenance.

[0003] However, the existing grates installed at the drainage outlets of reservoirs do not have self-cleaning capabilities. When there is too much garbage in the reservoir, the grates will usually clog, affecting drainage efficiency and increasing safety hazards. Therefore, the drainage outlet grates need to be manually removed regularly to assist in cleaning, which increases the labor intensity of reservoir maintenance personnel. Utility Model Content

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a garbage-proof grid separation device for reservoir drainage outlets, which can effectively prevent large-volume garbage from clogging the grid, ensure normal drainage of reservoir drainage outlets, eliminate safety hazards, and at the same time eliminate the need for manual cleaning, reducing the labor intensity of maintenance personnel.

[0005] The reservoir drainage outlet anti-garbage grating separation device of this utility model includes an inlet tank and an outlet tank, which are separated by a grating plate. The inlet tank is used to connect to the drainage outlet of the reservoir. A cleaning claw assembly is rotatably connected to the grating plate. The cleaning claw assembly includes claw A and claw B, which are hinged together. Claw A and claw B are provided with openings, and the positions of the openings correspond to the positions of the openings on the grating plate to ensure smooth drainage under normal conditions. Motor A and Motor B are installed on one side of the cleaning claw assembly. Claw A is driven to rotate by motor A, and claw B is driven to rotate by motor B. The top surface of the water outlet tank is sealed and tilted. A cleaning electric cylinder is installed on one side of the water outlet tank, and a garbage storage box is provided on the other side of the water outlet tank.

[0006] The technical solution of this utility model is to provide a garbage-proof grid separation device for a reservoir drainage outlet. During normal drainage, the water flows through the cleaning claw assembly and the grid plate in sequence and flows out of the outlet tank. When the flow rate of the outlet tank reaches the set lower limit, the cleaning claw assembly is activated to grab the garbage and place it on the top plate of the outlet tank. Then, the cleaning electric cylinder pushes the garbage on the top plate of the outlet tank into the garbage storage box to complete the garbage self-cleaning.

[0007] Preferably, bearing seats are installed on both sides of the top of the grating plate, and the rotating shaft of the claw A is rotatably connected to the grating plate through the bearing seats; the bottom of the claw B is arc-shaped to facilitate the retrieval of garbage.

[0008] Preferably, the motor A is located below the motor B, and the motor A is connected to the rotating shaft of the claw plate A through a coupling; a double-row sprocket is also fitted on the rotating shaft of the claw plate A, and the double-row sprocket is rotatably connected to the rotating shaft of the claw plate A through a needle roller bearing.

[0009] Preferably, a driven sprocket is fixedly connected to one end of the rotating shaft of the claw B. The driven sprocket is connected to one side of the double-row sprocket via a long chain, and the other side of the double-row sprocket is connected to the driving sprocket via a short chain. The driving sprocket is fixedly connected to the output shaft of the motor B. When the motor B is activated, it can drive the double-row sprocket to rotate around the rotating shaft of the claw A. The double-row sprocket then drives the claw B to rotate around its rotating shaft via the long chain and the driven sprocket.

[0010] Furthermore, a cleaning plate is installed at the front end of the cleaning cylinder, and the bottom of the cleaning plate is in contact with the top surface of the water outlet tank.

[0011] Preferably, a pressure sensor is installed at the bottom of the garbage storage bin to detect the total weight of the garbage storage bin. The pressure sensor is electrically connected to the control system. When the total weight of the garbage storage bin reaches a set value, the control system issues an alarm to remind staff to remove the garbage from the garbage storage bin in a timely manner.

[0012] Preferably, an electric valve is installed on the inlet of the water inlet tank, and a flow meter is installed on the outlet of the water outlet tank. Both the flow meter and the electric valve are electrically connected to the control system.

[0013] The advantages of this utility model compared with the prior art are: The reservoir drainage outlet anti-garbage grating separation device of this utility model, when the flow meter detects that the flow rate of the outlet tank has reached the set lower limit, the cleaning claw assembly is activated to grab the garbage in the inlet tank and place it on the top plate of the outlet tank. Then, the cleaning electric cylinder pushes the garbage on the top plate of the outlet tank into the garbage storage box, completing the garbage self-cleaning. This utility model can prevent large-volume garbage from clogging the outlet, ensure normal drainage of the reservoir drainage outlet, eliminate safety hazards, and at the same time eliminate the need for manual dredging, reducing the labor intensity of maintenance personnel.
