Description

Technical Field

[0001] The utility model relates to the technical field of pumping station gates, in particular to a pumping station gate with an emergency discharge port. Background Technique

[0002] A pumping station is a transfer station in the urban sewage treatment pipe network system. Wastewater that cannot be directly discharged into the sewage treatment system is first collected in the pumping station and then transferred out of the pumping station by the lifting action of sewage pumps. In order to prevent accidents, an emergency discharge port needs to be set on the gate.

[0003] However, the emergency discharge ports on the existing gates are all controlled by motors to open and close the discharge ports. When the baffle opens and closes, it will rub against the gate. Coupled with the impact force of the water flow, a motor with a relatively large power is required to drive the baffle to open and close, resulting in high power consumption costs and great difficulty in opening and closing the baffle. Content of the Utility Model

[0004] The purpose of the utility model is to provide a pumping station gate with an emergency discharge port to solve the problem of large friction force between the baffle and the gate proposed in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A pumping station gate with an emergency discharge port, comprising:

[0006] A pumping station gate main body, a lead screw is inserted up and down inside the pumping station gate main body, and a buffer assembly is arranged on the back of the pumping station gate main body;

[0007] A discharge port assembly, the discharge port assembly includes a lead screw, a servo motor is installed above the lead screw, a nut pair is connected to the outer wall below the lead screw, an opening and closing plate is arranged on the outer wall of the nut pair, conveyor belts are attached to both sides of the opening and closing plate, a rotating roller is arranged on the inner wall of the conveyor belt, and a fixed shaft penetrates through the inside of the rotating roller.

[0008] Preferably, the buffer assembly includes a shock absorber, one end of the shock absorber is connected with a slider, a first shaft rod is arranged inside the slider, a connecting rod is connected to the outer wall of the first shaft rod, a second shaft rod penetrates through the inside of the end of the connecting rod far away from the first shaft rod, fixed blocks are connected to both ends of the second shaft rod, and a triangular plate is installed on the side of the fixed block far away from the pumping station gate main body.

[0009] Preferably, the lead screw is rotatably connected to the pumping station gate main body, and the servo motor is fixedly connected to the pumping station gate main body.

[0010] Preferably, the nut pair is fixedly connected to the opening and closing plate, and the opening and closing plate is provided with a hole corresponding to the lead screw.

[0011] Preferably, the rotating roller is rotatably connected to the fixed shaft, and the fixed shaft is fixedly connected to the main body of the pumping station gate.

[0012] Preferably, both ends of the shock absorber are fixedly connected to the main body of the pumping station gate and the slider respectively, and the connecting rod is rotatably connected to the first shaft rod.

[0013] Preferably, the connecting rod is fixedly connected to the second shaft rod, and the fixed block is fixedly connected to the triangular plate.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] (1) Through the setting of the discharge port assembly of the new type of pumping station gate, when it is necessary to open the discharge port, the servo motor is started. The servo motor drives the lead screw to rotate, the lead screw drives the nut pair to move upward, the nut pair drives the opening and closing plate to move upward, the opening and closing plate moves together with the conveyor belt, and the rotating roller starts to rotate, converting the sliding friction between the opening and closing plate and the main body of the pumping station gate into the rolling friction between the conveyor belt and the rotating roller, greatly reducing the frictional force, eliminating the need to use a high-power motor for driving, and reducing the power consumption.

[0016] (2) Through the setting of the buffer assembly of the new type of pumping station gate, the impact force of the water flow on the main body of the pumping station gate is blocked by the triangular plate. After the triangular plate is impacted, the impact force is finally transmitted to the shock absorber, and the shock absorber plays a role in energy dissipation and vibration reduction, avoiding damage to the triangular plate caused by excessive impact force. The triangular plate can disperse the impact force to both sides, avoiding damage to the triangular plate itself caused by concentrated impact force. Description of the Drawings
