A type of ecological flow stratified control gate for hydropower stations

Abstract

This utility model discloses an ecological flow stratified control gate for hydropower stations, relating to the field of hydropower station gate technology. It includes a gate seat with two gates slidably connected inside. In this utility model, a designated motor drives a reel to rotate, enabling upward control of either gate one or gate two. During the upward movement of gate two, gate two drives an adjacent L-shaped frame upward, causing a filter screen to block the two vertical plates. The upward movement of gate two allows water flow to pass through, and the inclined surfaces of two guide plates guide water and debris between the two vertical plates. After the vertical plates and filter screen collect the debris, the filter screen discharges the water. When gate two moves downward, the filter screen moves upward, facilitating the removal of debris collected between the two vertical plates. Workers can remove the debris using shovels or other tools and temporarily store it inside the partition, facilitating the collection of debris in the water and ensuring the stability of the downstream ecosystem.

Description

Technical Field

[0001] This utility model relates to the field of hydropower station gate technology, specifically a hydropower station ecological flow stratification control gate. Background Technology

[0002] With continuous technological advancements, the ecological flow stratified control gates of hydropower stations will become more intelligent and automated. Future control systems will possess stronger data processing and analysis capabilities, enabling real-time and precise sensing of various information from the reservoir and downstream river channels. They will then automatically make more scientific and rational control decisions, achieving refined management of ecological flow. Utilizing the temperature differences at different depths within the reservoir, stratified water intake will be achieved by setting up intakes and corresponding gates at different elevations. This will reduce the temperature difference between the discharged water and the natural river channel, mitigating adverse impacts on downstream fish and other aquatic life.

[0003] Stratified water intake, with its unique method, precisely draws water from different depths in the reservoir, effectively regulating the temperature of the discharged water and ensuring the stability of the downstream ecosystem. However, stratified water intake devices often carry a large amount of debris such as aquatic plants, plastic bags, and branches. Once these debris mixes into the discharged water flow, they can easily clog the gates, hindering their normal opening and closing, increasing maintenance difficulty and costs. Some existing gates are not convenient for collecting debris and lack efficient debris filtration and collection functions. The accumulation of debris can also interfere with the speed and direction of water flow, reduce the accuracy of ecological flow regulation, and even affect the stability of the downstream ecosystem.

[0005] To solve the above-mentioned technical problems, this utility model provides a hydropower station ecological flow stratified control gate, comprising,

[0006] The gate seat has two gates slidably connected inside, and a gate 2 is slidably connected between the two gates 1. Two vertical plates are fixed to the top of the gate seat, and a filter screen is slidably connected between the two vertical plates.

[0007] Furthermore, guide plates are fixedly connected to one side of each of the two gates, and the two guide plates are symmetrically distributed.

[0008] Furthermore, two limiting frames are symmetrically fixed inside the gate seat, and the gate is slidably connected to the adjacent limiting frame.

Multiple motors are fixedly connected to the top of the support frame, and the output end of the motor is fixedly connected to the adjacent coil. A wire rope is fixedly connected to the inner wall of the coil, and the top ends of both gate one and gate two are fixedly connected to the adjacent wire rope.

[0010] Furthermore, two partitions are symmetrically fixed to the top of the gate seat.

[0011] Furthermore, a mounting plate is fixedly connected to the bottom of the support frame, and a limiting shell is fixedly connected to the bottom end of the mounting plate. Two L-shaped frames are slidably connected inside the limiting shell.

[0020] 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.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a hydropower station ecological flow stratified control gate, including a gate seat 10, two gates 11 are slidably connected inside the gate seat 10, a gate 2 12 is slidably connected between the two gates 11, two vertical plates 13 are fixedly connected to the top of the gate seat 10, and a filter screen 131 is slidably connected between the two vertical plates 13.

[0022] In practice, the designated motor 143 is started to drive the reel 141 to rotate. The reel 141 winds the wire rope 142, which can control the upward movement of gate 11 or gate 2 12. During the upward movement of gate 2 12, gate 2 12 drives the adjacent L-shaped frame 161 to move upward. Through the transmission of gear 164 and two racks 162, the upper L-shaped frame 161 drives the filter screen 131 to move downward. After gate 2 12 moves upward, the filter screen 131 blocks the two vertical plates 13. After the water flows near gate 11, gate 2 12 moves upward and opens... When the water flows, the inclined surfaces of the two guide plates 111 work together to guide the water flow and debris between the two vertical plates 13, preventing debris from accumulating at the gate 11. This actively guides the debris. After the vertical plates 13 and the filter screen 131 collect the debris, the filter screen 131 can drain the water. After the gate 2 12 moves down, the filter screen 131 moves up, making it easy to remove the debris collected between the two vertical plates 13. Workers can use shovels or other tools to remove the debris and put it into the partition 15 for temporary storage. Once a large amount of debris has accumulated, it will be disposed of in a unified manner.

[0023] See Figure 1-2 Guide plates 111 are fixedly connected to one side of each of the two gates 11, and the two guide plates 111 are symmetrically distributed.

[0024] Two limiting frames 112 are symmetrically fixed inside the gate seat 10, and the gate 11 is slidably connected to the adjacent limiting frame 112.

[0025] In practice, after the water flows near the vicinity of gate 11, gate 2 12 is lifted to open the water flow. The inclined surfaces of the two guide plates 111 cooperate to guide the water flow and debris between the two vertical plates 13, preventing debris from accumulating at gate 11 and actively guiding the debris. The gate 111 is vertically slidably limited by the limit frame 112, so that when gate 11 is lifted by the wire rope 142, the position of gate 11 is prevented from shifting.

[0026] See Figure 1 Two partition plates 15 are symmetrically fixed to the top of the gate seat 10.

[0027] In practice, after the vertical plate 13 and filter screen 131 collect the debris, the filter screen 131 can drain the water. Then, the gate 12 is lowered again and the filter screen 131 is raised. The staff can remove the debris with tools such as shovels and put it into the partition 15 for temporary storage. After a large amount of debris has accumulated, it will be processed in a unified manner.

[0028] See Figure 3-4 A support frame 14 is fixedly connected to the top of the gate seat 10. Multiple coils 141 are rotatably connected to the top of the support frame 14. Multiple motors 143 are fixedly connected to the top of the support frame 14. The output end of the motor 143 is fixedly connected to the adjacent coil 141. A wire rope 142 is fixedly connected to the inner wall of the coil 141. The tops of gate one 11 and gate two 12 are both fixedly connected to the adjacent wire rope 142.

[0029] The bottom of the support frame 14 is fixedly connected to the mounting plate 165, and the bottom end of the mounting plate 165 is fixedly connected to the limiting shell 16. The inside of the limiting shell 16 is slidably connected to two L-shaped frames 161. The top of the filter screen 131 is fixedly connected to the fixing plate 132. The fixing plate 132 and the gate 12 are both fixedly connected to the adjacent L-shaped frame 161.

[0030] Two L-shaped frames 161 are fixedly connected to opposite sides with racks 162. A shaft 163 is rotatably connected between the two inner walls of the limiting shell 16. A gear 164 is fixedly sleeved on the outer wall of the shaft 163. Both racks 162 mesh with the gear 164.

[0031] In practice, the designated motor 143 is started to drive the coil 141 to rotate. The coil 141 winds the steel wire rope 142, which can adjust the upward movement of gate 11 or gate 2 12. During the upward movement of gate 2 12, gate 2 12 drives the adjacent L-shaped frame 161 to move upward. Through the transmission of gear 164 and two racks 162, the upper L-shaped frame 161 drives the filter screen 131 to move downward. After gate 2 12 moves upward, the filter screen 131 blocks the two vertical plates 13. The filter screen 131 can filter out water and leave the impurities. After gate 2 12 moves downward, the filter screen 131 moves upward, which makes it convenient to remove the impurities collected between the two vertical plates 13.

[0032] Working principle: The designated motor 143 drives the reel 141 to rotate, which winds the steel wire rope 142, allowing for upward movement of either gate 11 or gate 2 12. During the upward movement of gate 2 12, gate 2 12 drives the adjacent L-shaped frame 161 upward. Through the transmission of gear 164 and two racks 162, the upper L-shaped frame 161 drives the filter screen 131 downward. After gate 2 12 moves upward, the filter screen 131 blocks the two vertical plates 13. After the water flows near gate 11, gate 2 12 is lifted and opens... When the water flows, the inclined surfaces of the two guide plates 111 work together to guide the water flow and debris between the two vertical plates 13, preventing debris from accumulating at the gate 11. This actively guides the debris. After the vertical plates 13 and the filter screen 131 collect the debris, the filter screen 131 can drain the water. After the gate 2 12 moves down, the filter screen 131 moves up, making it easy to remove the debris collected between the two vertical plates 13. Workers can use shovels or other tools to remove the debris and put it into the partition 15 for temporary storage. Once a large amount of debris has accumulated, it will be disposed of in a unified manner.
