Description

Technical Field

[0001] This utility model belongs to the technical field of drainage pumping stations, and relates to an outlet flood control gate structure for a drainage pumping station. Background Technology

[0002] The outlet floodgate structure of a drainage pumping station is a hydraulic facility that combines drainage and flood control functions. It is typically located at the connection between the pumping station's outlet pipe and the external river (or flood control area). Its main function is to open during drainage operations to allow floodwater to flow out smoothly, and to close when the water level of the external river is higher than that of the internal river (or protected area) to prevent floodwater from flowing back into the protected area, thereby ensuring flood control safety within the area.

[0003] This structure generally consists of a gate body (including gate piers, gate bottom plate, etc.), gate (mostly flat steel gates or arc gates), hoist (such as screw type or hydraulic type hoist), and auxiliary facilities such as water stop and monitoring. Through coordinated operation with the pumping station, it achieves the dual functions of "draining floodwater and blocking floods", and is a key link in ensuring the safety of the flood control and drainage system in the drainage pumping station project.

[0004] Currently, most drainage pumping stations use gates with limited functionality. Traditional gates often only have a single opening and closing mechanism, making it difficult to achieve precise flow control when facing small drainage demands. As a result, the gates can only be fully opened, leading to low drainage efficiency and unreasonable use of water resources. At the same time, during the gate opening process, debris such as dead branches and plastic waste floating on the upstream water surface will be carried into the downstream river channel with the water flow. This not only affects the aesthetics of the water body but may also block downstream water conservancy facilities and even aggravate water pollution, negatively impacting the entire aquatic ecological environment. Utility Model Content

[0005] The purpose of this utility model is to provide an outlet flood control gate structure for a drainage pumping station, which solves the problems of existing gates having a single function, lacking the ability to filter debris from the water surface, and controlling water flow at low flow rates.

[0006] The technical solution adopted in this utility model is a flood control gate structure at the outlet of a drainage pumping station, including a gate-frame type support frame. A vertically placed fixed seat is fixed at the lower end of each of the two legs of the support frame. A lifting assembly is installed at the center of the upper crossbeam of the support frame. The lifting assembly passes through the top crossbeam of the support frame and connects to the gate plate. The gate plate slides up and down along the two fixed seats. A drainage hole is opened on the gate plate, and a baffle is installed upstream of the drainage hole. The top of the baffle is connected to the piston end of a hydraulic rod, and the fixed end of the hydraulic rod is connected to the lower surface of the upper crossbeam of the support frame. A filter plate is provided between the two fixed seats; the filter plate is located upstream of the baffle.

[0007] The features of this utility model also include:

[0008] The baffle moves along the mounting slot in the direction of movement, and the baffle moves up and down along the slot.

[0009] The filter plate has sliders fixed to both ends, and two fixed seats have limiting grooves on their inner sides that cooperate with the sliders. A handle is fixed to the upper end of the filter plate.

[0010] The lifting assembly includes a motor mounted on top of the support frame. The output end of the motor is connected to a screw that passes downward through the crossbeam of the support frame. A horizontal fixing plate is fixedly connected between the two legs at the lower end of the support frame. The lower part of the screw is rotatably connected to the fixing plate through a bearing.

[0011] A threaded sleeve is fitted on the screw, and a fixing frame is fixedly connected to the outer wall of the threaded sleeve. The fixing frame is fixedly connected to one side of the gate plate; a reinforcing rib is fixed between the fixing frame and the gate plate.

[0012] A horizontally mounted sliding plate is fixedly connected to the outer wall of the threaded sleeve; a sliding rod is fixed between the fixed plate and the upper crossbeam of the support frame, the sliding rod passes through the sliding plate and is slidably connected to the sliding plate, and the sliding rod is parallel to the threaded rod.

[0013] The sliding plate extends towards the filter plate at both ends, and each end is connected to the upper end of a vertical extension plate. A brush plate with a brush head is connected between the lower ends of the two extension plates, and the brush head contacts the surface of the filter plate.

[0014] A limiting strip is installed on the outer wall of the extension plate in the vertical direction, and a retaining groove is opened on the inner wall of the fixing seat to cooperate with the limiting strip.

[0015] Limiting blocks are installed on both sides of the gate plate, and a connecting groove is opened on the inner wall of the fixed seat to slide and connect with the limiting blocks.

[0016] The outer side of the mounting base is equipped with a insert plate.

[0017] The beneficial effects of this utility model are:

[0018] This invention enables flexible raising and lowering of the gate plate through various components, allowing for precise control of water discharge speed and flow rate. This ensures rapid water release during flood drainage, preventing waterlogging, and allows for timely closure to block water flow during floods, preventing backflow risks and enhancing the dual controllability of drainage and flood control. Combined with auxiliary components to filter impurities from the upstream water surface, it intercepts floating debris such as branches and garbage, as well as silt particles. This prevents impurities from clogging the gate track and wearing down seals, reducing equipment failure and maintenance costs. Furthermore, it prevents pollutants from entering the downstream area, protecting the aquatic ecosystem and water quality. This approach balances water conservancy efficiency with water environment safety, achieving a synergistic improvement in both functionality and environmental protection. Attached Figure Description

[0024] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0025] The outlet flood control gate structure of the drainage pumping station of this utility model, such as Figure 1 As shown, it includes a door frame-type support frame 1, with a vertically placed fixed seat 2 fixed at the bottom of each of the two feet of the support frame 1, and a lifting component 4 installed at the center of the upper crossbeam of the support frame 1; the lifting component 4 passes through the top crossbeam of the support frame 1 and is connected to the gate plate 3 which is slidably connected to the fixed seat 2; the support frame 1 and the fixed seat 2 together provide support for the flood control gate, and the lifting component 4 controls the change of the vertical movement height of the gate plate 3.

[0026] like Figure 2 As shown, the gate plate 3 has a drainage hole 9, such as Figure 3 As shown, a baffle 5 is installed upstream of the gate plate 3. The top of the baffle 5 is connected to the piston end of the hydraulic rod 8, and the other end of the hydraulic rod 8 is connected to the lower surface of the upper crossbeam of the support frame 1. The gate plate 3 has a mounting slot 6 for the baffle 5 to move in the direction of movement. The baffle 5 moves up and down along the slot 6. The hydraulic rod 8 controls the baffle 5 to move up and down. When the baffle 5 is fully lowered, it can completely block the drain hole 9.

[0027] A filter plate 7 is provided between two fixed seats 2; sliders 11 are fixed to the left and right end faces of the filter plate 7, and limiting grooves 10 that cooperate with sliders 11 are opened on the inner side of the two fixed seats 2. A handle 12 is fixed to the upper end of the filter plate 7. By operating the handle 12, the filter plate 7 can slide up and down along the fixed seat 2.

[0028] like Figure 4As shown, the lifting assembly 4 includes a motor 401 mounted on the top of the support frame 1. The output end of the motor 401 is connected to a screw 402. The screw 402 passes through the upper crossbeam of the support frame 1, and its lower end is rotatably connected to a fixing plate 403 horizontally fixed to the lower end of the support frame 1 via a bearing.

[0029] A threaded sleeve 404 is fitted on the screw 402. A fixing bracket 405 is fixedly connected to the outer wall of the threaded sleeve 404.

[0031] Both ends of the sliding plate 406 extend toward the filter plate 7 and are fixedly connected to one end of a pair of vertically downward extension plates 16. A horizontally arranged brush plate 17 is connected between the lower ends of the two extension plates 16. The brush plate 17 has a brush head 18, which contacts the surface of the filter plate 7. A limiting strip 20 is installed on the outer wall of the vertical extension plate 16, and a retaining groove 21 is opened on the inner wall of the fixing seat 2 to cooperate with the limiting strip 20. When the lifting component controls the gate plate 3 to rise, the brush head passes over the surface of the filter plate 7 and cleans the water plants and debris that are blocked on the filter plate.

[0032] Limiting blocks 14 are installed on both sides of the gate plate 3, and a connecting groove 13 is opened on the inner wall of the fixed seat 2 to slide and connect with the limiting blocks 14; when the gate plate 3 moves up and down, it slides along the connecting groove 13.

[0033] The two fixing seats 2 are provided with insert plates 15 on the outside, which limit the installation of the fixing seats 2 in the drainage station and in the soil or cement, and play a fixing role.

[0034] The working principle of the outlet flood control gate structure of this utility model drainage pumping station is as follows:

[0035] When in use, when a small flow of water is required, the hydraulic rod 8 is activated to lift the baffle 5. As the baffle 5 rises inside the slot 6, the water flows out through the drain hole 9 inside the gate plate 3. At this time, the filter plate 7 can filter out the debris in the upstream water.

[0036] When a large volume of water needs to be discharged, the output shaft of motor 401 is turned on to drive screw 402 to rotate. Since the position of screw remains unchanged, threaded sleeve 404 drives fixed frame 405 and sliding plate 406 to rise. Fixed frame 405 drives gate plate 3 to rise along fixed seat 2. Sliding rod 407 provides auxiliary limit to rise and discharge water. The speed and height of gate plate 3 rising are controlled by the threads on motor 401 and screw 402.

[0037] Meanwhile, as the sliding plate 406 moves, it will drive the extension plate 16 to move in conjunction with the limiting strip 20 within the fixed groove 21. The brush head 18 can brush the filter plate 7. Each time the gate plate 3 rises and falls, the filter plate 7 will be cleaned once, thus preventing the filter plate 7 from becoming clogged.
