Description

Technical Field

[0001] This utility model relates to the technical field of bottom-opening weir gate diversion wells, and in particular to a bottom-opening weir gate diversion well. Background Technology

[0002] A hydraulic bottom-opening weir gate is a type of rainwater and sewage separation device. Used in pipelines, culverts, or channels, it serves to flush, prevent backflow, and regulate flow. Because it opens downwards and does not occupy upper space, it is called a bottom-opening weir gate.

[0003] In existing bottom-opening weir gate diversion wells, such as the intelligent bottom-opening weir gate diversion well disclosed in utility model patent application number 202123297549.6, the utility model achieves rolling contact between the two sides of the gate and the ball bearings inside the slide groove during the downward movement of the gate, thereby reducing the friction between the gate and the slide groove. Furthermore, due to the magnetic repulsion between strong magnetic block a and strong magnetic block b, the sealing block installed at one end of strong magnetic block b can always maintain a tight fit with the outside of the gate. Even after the thickness of the sealing block decreases due to frictional wear, the sealing performance between the gate and the slide rail will always be maintained due to the outward push of strong magnetic block b.

[0004] However, during the use of the bottom-opening weir gate diversion well, the weir gate, which is subjected to water flow impact, will experience insufficient sealing and equipment damage due to continuous impact over a long period of time, increasing maintenance costs. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a bottom-opening weir gate diversion well that reduces the impact of water flow on the weir gate during use by setting a buffer mechanism and a filtration mechanism, thereby improving the service life of the equipment and reducing maintenance costs.

[0006] This utility model provides a bottom-opening weir gate diversion well, which includes a water passage mechanism; it also includes a buffer mechanism, an opening and closing mechanism, a contact mechanism, and a filter mechanism. The buffer mechanism is installed inside the water passage mechanism, the opening and closing mechanism is installed inside the water passage mechanism, the contact mechanism is installed on the opening and closing mechanism, and the filter mechanism is installed on the contact mechanism.

[0007] The water-passing mechanism facilitates water passage, the buffering mechanism provides buffering, the opening and closing mechanism enables opening and closing, the contact mechanism provides soft contact, and the filtration mechanism performs filtration. Water passes through the water-passing mechanism, discharges water by opening and closing the mechanism, the buffering mechanism cushions the water flow, the contact mechanism prevents the opening and closing mechanism from jamming when it reaches its lowest point, and the filtration mechanism filters impurities from the water surface. As a result, during the use of the bottom-opening weir gate diversion well, the impact of water flow on the weir gate can be reduced, the service life of the equipment can be increased, and maintenance costs can be reduced.

[0008] Preferably, the water-passing mechanism includes a well body, two sets of slide rails, and a mating block. The two sets of slide rails are installed inside the well body, and the mating block is installed at the upper end of the well body. Water flows through the well body, and the mating block provides a seal.

[0009] Preferably, the buffer mechanism includes a buffer block, multiple sets of inlet pipes, and multiple sets of return pipes. The buffer block is installed inside the well body, and the multiple sets of inlet pipes are installed inside the buffer block. Each set of inlet pipes is equipped with two sets of return pipes. The buffer block buffers the water flow, the inlet pipes allow water to pass through, and the return pipes and the inlet pipes impact each other to reduce the impact force of the water flow.

[0010] Preferably, the opening and closing mechanism includes a weir gate and a hydraulic cylinder. The weir gate is slidably mounted on two sets of slide rails, and the hydraulic cylinder is installed inside the well body, with the output end of the hydraulic cylinder connected to the weir gate. The weir gate is opened and closed by driving the hydraulic cylinder to operate.

[0011] Preferably, the contact mechanism includes a base frame and two sets of springs. The base frame is slidably mounted on the weir gate by the two sets of springs. The support of the base frame by the springs allows for a certain amount of movement when the weir gate is lowered.

[0012] Preferably, the filtration mechanism includes a filter screen and a baffle, with the filter screen mounted on a base frame and the baffle mounted on the base frame; the baffle blocks impurities, and the filter screen filters the impurities.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: water is passed through the water passage mechanism, water is discharged through the opening and closing mechanism, the water flow is buffered through the buffer mechanism, the opening and closing mechanism is prevented from getting stuck when it is lowered to the lowest point through the contact mechanism, and impurities on the water surface are filtered through the filtration mechanism. Thus, during the use of the bottom-opening weir gate diversion well, the impact of water flow on the weir gate can be reduced, the service life of the equipment can be improved, and the maintenance cost can be reduced.
