Description

Technical Field

[0001] This utility model relates to the field of gate equipment technology, and in particular to an adjustable bottom shaft hydraulic linkage flap gate. Background Technology

[0002] In the field of water conservancy and hydropower engineering construction, with the increasing demand for urban water supply security, landscape water body creation, ecological environment improvement, agricultural irrigation, hydropower generation and other diversified needs, water control structures such as flap gates, conventional sluice gates and rubber dams have been widely used.

[0003] The existing bottom-shaft type flap gate is a common water control structure. Its typical components include a bottom shaft, gate leaf, opening and closing device, and a separate bearing device. The gate leaf is fixedly connected to the bottom shaft, and the bottom shaft is detachably connected to the bottom sill of the gate chamber through at least two separate bearing devices. The opening and closing device drives the bottom shaft to rotate around its own axis, thereby driving the gate leaf to rotate synchronously, thus realizing the opening or closing of the sluice gate opening. Although this technical solution has improved the convenience of gate cleaning, it still has obvious limitations in actual operation: when the gate is opened in the direction of water flow, the gate body directly bears the huge impact force and pressure of the water flow. This not only significantly increases the resistance and energy consumption of the opening and closing process, leading to increased difficulty in opening, but also easily causes fatigue damage to the gate body, bottom shaft, and bearing device due to long-term repeated action of water flow load, seriously affecting the operational stability and service life of the entire gate system.

[0004] Based on this, we now offer an adjustable bottom shaft hydraulic linkage flap gate, which can eliminate the drawbacks of existing devices. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] like Figures 1-6As shown, this utility model embodiment provides an adjustable bottom shaft hydraulic linkage flap gate, including a gate plate 200 disposed at the end of the gate body 100. The cross-section of the gate plate 200 corresponds to the cross-sectional area of ​​the gate body 100 opening. The bottom of the gate plate 200 is rotatably connected to the gate body 100 via a flipping bottom shaft 201. The flipping bottom shaft 201 is connected to a drive device for driving its flipping. The top of the gate plate 200 is provided with a light structure 300. The surface of the gate plate 200 is provided with a sealing frame 202 that matches the end of the gate body 100. A drain outlet 205 is opened on the surface of the gate plate 200. The water inlet end of the drain outlet 205 is a rectangular structure. The drain outlet 205 is provided with a guide ramp 204. The guide ramp 204 can guide the water flow upward, thereby improving the waterfall effect. The gate plate 200 is provided with a segmented partition module that matches the drain outlet 205. The drainage volume and the width of the waterfall can be adjusted through the segmented partition module.

[0031] The segmented partition module includes a partition slide groove 402 set on the upper end of the gate 200. The partition slide groove 402 is connected to the drain outlet 205. Multiple partitions 403 are slidably arranged in the partition slide groove 402. A sealing slide group is provided between adjacent partitions 403. The upper end of each partition 403 is connected to a lifting push rod 401 for driving it to move up and down. The lifting push rod 401 can be a hydraulic rod. Under the drive of the lifting push rod 401, the partition 403 can slide along the partition slide groove 402. When only one partition 403 moves up, the width of the waterfall is the smallest.

[0032] The sealing slide block includes an arc-shaped protrusion 404 and an arc-shaped groove 405 provided on the partition 403. The arc-shaped protrusion 404 and the arc-shaped groove 405 are matched. The inner wall of the partition slide groove 402 is also provided with corresponding arc-shaped protrusions 404 and arc-shaped grooves 405, so that the sealing effect between the multiple partitions 403 and the gate 200 is better.

[0033] It should be noted that the drain outlet 205 is located at the upper quarter position of the gate 200, so that the water flow has a certain water pressure when it sprays out along the drain outlet 205, thus improving the waterfall effect;

[0034] The inlet end of the drain outlet 205 is equipped with a filter screen 203. The filter screen 203 can filter impurities in the water flow to prevent impurities from affecting the waterfall effect and also purify the water quality. When the water level is low, the hole needs to be cleaned in time. This maintenance work needs to be done by the staff.

[0035] The lighting structure 300 includes a horizontally arranged lighting substrate 305. The lighting substrate 305 is connected and fixed to the top of the gate 200 via a substrate support rod 306, thus creating an overflow gap between the lighting substrate 305 and the gate 200 to protect the lighting structure 300. Multiple fixed covers 304 are fixedly mounted on the upper end of the lighting substrate 305. An installation area is provided on the surface of the lighting substrate 305 between adjacent fixed covers 304, and a lighting assembly 303 is mounted on this installation area. A movable cover 302 is slidably positioned at the installation area, and the movable cover 302 is connected to the fixed covers 304. The movable cover 302 is designed to slide sideways, with its length exceeding that of the installation area to protect the lighting assembly 303. Multiple movable covers 302 are connected to a push module that drives them to slide. The push module can cause the movable cover 302 and the fixed cover 304 to be offset or overlapped. When offset, the multiple fixed covers 304 and the movable cover 302 form a protective shell to protect the lighting assembly 303. When overlapped, the lighting assembly 303 is exposed for lighting performances. It should be noted that the outer ports of the movable covers 302 at both ends are closed, while the movable cover 302 in the middle is open at both ends.

[0036] The pushing module includes a pushing rod 301 disposed at the end of the light substrate 305. The output end of the pushing rod 301 is provided with a connecting frame 308. The connecting frame 308 is connected to the movable cover 302 through a connecting block. The pushing rod 301 pulls the connecting frame 308, thereby driving multiple movable covers 302 to move synchronously.

[0037] The light base plate 305 is provided with a sealing groove 307 that matches the movable cover 302. Both the sealing groove 307 and the bottom cross section of the movable cover 302 are T-shaped structures.

[0038] The fixed cover 304 is provided with a sealing strip on the outside that matches the inner wall of the movable cover 302, which makes the sealing performance between the movable cover 302 and the fixed cover 304 better.

[0039] Working principle: During use, the gate 200 is rotated and engaged with the gate body 100. When the sealing frame 202 presses against the surface of the gate body 100, a seal is completed. When the gate 200 rotates, the segmented partition module can be opened to reduce the resistance when the gate 200 rotates. When the water volume in the gate 200 increases, the drain outlet 205 can be opened through the segmented partition module, allowing the water to spray out along the drain outlet 205. The sprayed water will rise along the guide slope 204, thus forming a waterfall. Combined with the lighting effect of the lighting structure 300, the equipment becomes more beautiful and more visually appealing.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
