Description

Technical Field

[0001] This utility model relates to the field of gate device technology, specifically an adjustable water flow guiding gate device for water diversion projects. Background Technology

[0002] Adjustable flow guiding gate devices in water diversion projects are mechanical devices used in water conservancy projects to precisely control water flow, water level, and direction by adjusting the gate opening. They are active control devices used to regulate water flow in water conservancy projects, and typically consist of a gate body, a drive system, and a control system. They precisely regulate the flow cross-sectional area by changing the gate opening, thereby achieving dynamic management of flow, water level, or flow direction. They are applied in inter-basin water diversion projects, reservoir and river management, and environmental protection and municipal engineering.

[0003] Patent document CN222500146U discloses a hydraulic gate device, which includes a gate frame. A lower gate is attached to the front edge of the inner bottom end of the gate frame. Both side walls of the lower gate are attached to the inner wall of the gate frame, and a guide mechanism is provided between the side walls of the lower gate and the inner wall of the gate frame. An upper gate is attached to the rear end of the lower gate near its upper edge. Slide plates are fixedly connected to the upper edges of both side walls of the upper gate. The inner wall of the gate frame has grooves corresponding to two slide plates, which slide in a sliding engagement with the two slide plates. A fixing mechanism is provided between the upper gate and the gate frame. This hydraulic gate can be raised in sections during water release operations. When it is not necessary to raise the upper gate, only the lower gate needs to be raised, thereby reducing the workload of the staff. At the same time, this hydraulic gate facilitates the control of the water flow.

[0004] However, the aforementioned hydraulic gate device in the publicly available literature mainly considers that when there is no need to raise the upper gate, only the lower gate needs to be raised, thereby reducing the workload of the staff. At the same time, this hydraulic gate is convenient for controlling the size of the water flow, but it is not convenient for maintaining the downstream ecological water demand.

[0005] In view of this, it is necessary to develop a permeable mechanism to maintain the downstream ecological water demand and prevent the river from drying up. Utility Model Content

[0006] The purpose of this utility model is to provide an adjustable water flow guiding gate device for water diversion projects, so as to solve the technical problem mentioned in the background art of enabling the adjustable water flow guiding gate device of water diversion projects to have a water permeability function.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an adjustable water flow guiding gate device for water diversion projects, comprising: a gate frame and a gate plate, wherein the outer wall of the gate plate is provided with a water permeable mechanism, the water permeable mechanism being used to maintain downstream ecological water demand and prevent river flow interruption;

[0008] The permeable mechanism includes a permeable channel, a shielding net, and a sealing plate. The inner wall of the gate plate is provided with multiple sets of permeable channels. The outer wall of the gate plate is equipped with a shielding net. An assembly block is installed on the top of the shielding net. The outer wall of the gate plate is provided with an assembly screw groove. An assembly screw is installed on the outer wall of the assembly block, and one end of the assembly screw extends into the interior of the assembly screw groove. The outer wall of the gate plate is equipped with a sealing plate. The outer wall of the gate plate is provided with multiple sets of disassembly screw grooves. A disassembly screw is installed on the outer wall of the sealing plate, and one end of the disassembly screw extends into the interior of the disassembly screw groove.

[0009] Preferably, a protective shell is installed on the top of the gate frame, an electric telescopic rod is installed on the inner wall of the protective shell, a connecting rod is installed at the output end of the electric telescopic rod, and a gate plate is installed at the bottom of the connecting rod.

[0010] Preferably, the outer wall of the gate frame is provided with an emergency operation mechanism, which is used to move the gate plate by manual rotation when the electric telescopic rod is damaged.

[0011] Preferably, the emergency operation mechanism includes a mounting and dismantling screw groove, a mounting and dismantling screw rod, and a lower mounting plate. The top of the gate plate is provided with two sets of mounting and dismantling screw grooves, the top of the gate plate is equipped with a lower mounting plate, and the bottom of the lower mounting plate is equipped with a mounting and dismantling screw rod.

[0012] Preferably, the top of the lower mounting plate is provided with a mounting screw groove, the bottom of the connecting rod is provided with a first upper mounting plate, the inner wall of the gate frame is provided with a rotating screw groove, and the inner wall of the rotating screw groove is provided with a rotating screw.

[0013] Preferably, a bearing is installed at the bottom of the rotating screw, and a second upper mounting plate is installed at the bottom of the bearing.

[0014] Preferably, the outer walls of both the first and second upper mounting plates are equipped with mounting screws, and the mounting screws and mounting screw grooves are matched.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model maintains downstream ecological water demand and prevents river flow interruption by installing a permeable mechanism. Existing gate plates can block the water source of a river, leading to river flow interruption. When the downstream river needs daily water supply, the frequent opening and closing of the gate plate is cumbersome. Therefore, this needs to be improved by creating regularly arranged permeable channels on the surface of the gate plate to allow some water flow through, maintaining a minimum downstream ecological water demand and preventing river flow interruption. The position of the sealing plate is manually set according to needs. When a minimum continuous downstream water supply is required, the disassembly screw is removed from the disassembly screw groove located below the gate frame, and then the sealing plate is moved from one side of the gate plate and then moved above the gate plate. The disassembly screw is fixed into the disassembly screw groove located above, so that the sealing plate does not block the permeable channel. The shielding net is fixed into the assembly screw groove by the assembly screw, so that the shielding net is installed on one side (the water inlet end in the direction of water flow) of multiple sets of permeable channels. It is used to block sand, gravel and small algae, so as to prevent them from entering the permeable channel and causing blockage that is difficult to clean. Even if the shielding net is blocked on one side, it can be cleaned manually, which is convenient. This maintains the minimum ecological water demand downstream and avoids the need for multiple adjustments to the gate plate position due to river flow interruption. At the same time, the assembly screw groove, assembly screw, disassembly screw groove and disassembly screw are all treated with anti-corrosion coating. The coating is zinc-aluminum alloy coating, and the sealing plate and shielding net are made of anti-corrosion stainless steel.

[0017] 2. This utility model, by installing an emergency operation mechanism, allows the gate plate to be moved manually by rotation when the electric telescopic rod is damaged. Existing systems, when the electric telescopic rod is damaged and the gate opening needs adjustment, prevent emergency opening. Therefore, this needs improvement. When the electric telescopic rod is damaged, the mounting screw on the upper mounting plate is removed from the mounting screw groove on the lower mounting plate, separating the upper and lower mounting plates. Then, the lower mounting plate is rotated to remove the mounting screw from the mounting screw groove. The lower mounting plate is then moved below the rotating screw, and the lower mounting plate is rotated... The mounting plate secures the mounting screw to the mounting screw groove on the other side. Then, rotating the screw causes the second upper mounting plate and the lower mounting plate to fit together and be fixed to the mounting screw groove for assembly. The outer shaft of the bearing is fixedly connected to the outer wall of the second upper mounting plate, and the inner shaft of the bearing is fixedly connected to the outer wall of the rotating screw. When the rotating screw is rotated, because the second upper mounting plate and the lower mounting plate are fixedly connected, the inner shaft of the bearing rotates but does not cause the gate plate to rotate. However, the rotating screw rotates and moves in the rotating screw groove, causing the gate plate to move up and down, thus adjusting the opening of the gate plate in an emergency.

[0027] Please see Figure 1 and Figure 2 An adjustable water flow guiding gate device for water diversion projects includes: a gate frame 1 and a gate plate 5. A protective shell 2 is installed on the top of the gate frame 1, and an electric telescopic rod 3 is installed on the inner wall of the protective shell 2. A connecting rod 4 is installed at the output end of the electric telescopic rod 3, and the gate plate 5 is installed at the bottom of the connecting rod 4. The gate frame 1 is located in the water diversion project. The electric telescopic rod 3 is powered by an external power supply and moves the gate plate 5 up and down through a button in an external control box. Its function is to control the flow rate of water in real time by adjusting the opening of the gate plate 5, so as to meet the water demand of different time periods and different areas. For example, in agricultural irrigation, the water supply can be adjusted according to the crop growth cycle; in urban water supply systems, it can cope with the difference between peak and off-peak water use. During dry periods, the gate plate 5 can be closed to store water and ensure water supply security. For example, reservoir gates can maintain downstream ecological flow and residential water use during the dry season by adjusting the reservoir capacity.

[0028] Please see Figure 2 , Figure 3 and Figure 4The outer wall of the gate plate 5 is equipped with a permeable mechanism to maintain downstream ecological water demand and prevent river flow interruption. The permeable mechanism includes a permeable trough 6, a shielding net 7, and a sealing plate 11. The inner wall of the gate plate 5 is equipped with multiple sets of permeable troughs 6. The outer wall of the gate plate 5 is equipped with a shielding net 7, and an assembly block 8 is installed on the top of the shielding net 7. The outer wall of the gate plate 5 is equipped with an assembly screw groove 9. An assembly screw 10 is installed on the outer wall of the assembly block 8, and one end of the assembly screw 10 extends into the interior of the assembly screw groove 9. The outer wall of the gate plate 5 is equipped with a sealing plate 11, and the outer wall of the gate plate 5 is equipped with multiple sets of disassembly screws. The outer wall of the sluice gate 11 and the sealing plate 12 are fitted with a disassembly screw 13, one end of which extends into the interior of the disassembly screw groove 12. The existing gate plate 5 can block the water source of the river, causing the river to dry up. When the downstream area needs daily water supply, the frequent opening and closing of the gate plate 5 is cumbersome. Therefore, an improvement is needed. Regularly arranged permeable channels 6 are opened on the surface of the gate plate 5 to allow some water flow, maintaining the minimum ecological water demand downstream and preventing the river from drying up. The position of the sealing plate 11 is manually set according to requirements. When a minimum continuous water supply to the downstream is required, the disassembly screw 13 is removed from the disassembly screw groove 12 located below the gate frame 1. Then, the sealing plate 11 is moved out from one side of the gate plate 5, and then the sealing plate 11 is moved above the gate plate 5. The disassembly screw 13 is fixed into the disassembly screw groove 12 located above, so that the sealing plate 11 does not block the permeable channel 6. The shielding net 7 is fixed into the assembly screw groove 9 by the assembly screw 10. The shielding net 7 is then installed on one side (the inlet end in the direction of water flow) of the multiple sets of permeable channels 6, and the aperture of the permeable channel 6 is 1 cm. The mesh size of the shielding net 7 is 2mm, which is used to shield sand and small algae, preventing them from entering the permeable channel 6 and causing blockages that are difficult to clean. Even if a blockage occurs on one side of the shielding net 7, it can be cleaned manually, which is convenient. This maintains a minimum ecological water demand downstream and avoids river flow interruption, which would require multiple adjustments to the position of the gate plate 5. At the same time, the assembly screw groove 9, assembly screw 10, disassembly screw groove 12, and disassembly screw 13 are all treated with anti-corrosion coating, which is a zinc-aluminum alloy coating. The sealing plate 11 and the shielding net 7 are both made of corrosion-resistant stainless steel.

[0029] Please see Figure 2 and Figure 5The outer wall of the gate frame 1 is equipped with an emergency operation mechanism. This mechanism allows manual rotation of the gate plate 5 when the electric telescopic rod 3 is damaged. The emergency operation mechanism includes mounting and dismounting screw grooves 14, mounting and dismounting screws 15, and a lower mounting plate 16. The top of the gate plate 5 has two sets of mounting and dismounting screw grooves 14. A lower mounting plate 16 is installed on the top of the gate plate 5, and a mounting and dismounting screw 15 is installed at the bottom of the lower mounting plate 16. The top of the lower mounting plate 16 has a mounting screw groove 17. A first upper mounting plate 18 is installed at the bottom of the connecting rod 4. The inner wall of the gate frame 1 has a rotating screw groove 19. The inner wall of the groove 19 is provided with a rotating screw 20, and a bearing 21 is installed at the bottom of the rotating screw 20. A second upper mounting plate 22 is installed at the bottom of the bearing 21. Mounting screws 23 are installed on the outer walls of both the first upper mounting plate 18 and the second upper mounting plate 22, and the mounting screws 23 match the mounting screw grooves 17. Currently, when the electric telescopic rod 3 is damaged and the opening of the gate plate 5 needs to be adjusted, it cannot be opened in an emergency. Therefore, this needs to be improved. When the electric telescopic rod 3 is damaged, the mounting screws 23 on the first upper mounting plate 18 are removed from the mounting screw grooves 17 on the lower mounting plate 16. The screw is removed from the screw groove 17, separating the first upper mounting plate 18 and the lower mounting plate 16. Then, the lower mounting plate 16 is rotated to remove the mounting screw 15 from the mounting screw groove 14. The lower mounting plate 16 is then moved below the rotating screw 20, and the lower mounting plate 16 is rotated to fix the mounting screw 15 into the mounting screw groove 14 on the other side. Then, the screw 20 is rotated to bring the second upper mounting plate 22 and the lower mounting plate 16 together and fix them into the mounting screw groove 17 via the mounting screw 23 for assembly. The outer shaft of the bearing 21 is fixedly connected to the outer wall of the second upper mounting plate 22. The inner shaft of bearing 21 is fixedly connected to the outer wall of rotating screw 20. When rotating screw 20, since the second upper mounting plate 22 and lower mounting plate 16 are fixedly connected, the inner shaft of bearing 21 rotates but does not drive the gate plate 5 to rotate. However, rotating screw 20 rotates and moves in rotating screw groove 19, which drives the gate plate 5 to move up and down. In case of emergency, the opening of gate plate 5 can be adjusted. The mounting screw groove 14, mounting screw 15, mounting screw groove 17, mounting screw 23, rotating screw groove 19 and rotating screw 20 are all treated with anti-corrosion coating, which is a zinc-aluminum alloy coating.

[0030] Working principle: The gate frame 1 is located in the water diversion project. The electric telescopic rod 3 is powered by an external power supply and moves the gate plate 5 up and down via buttons in an external control box. Its function is to control the water flow in real time by adjusting the opening of the gate plate 5, meeting the water demand of different periods and areas. For example, in agricultural irrigation, the water supply can be adjusted according to the crop growth cycle; in urban water supply systems, it can cope with the differences between peak and off-peak water use. During dry periods, the gate plate 5 can be closed to store water and ensure water supply security. For example, reservoir gates regulate reservoir capacity to maintain downstream ecological flow and residential water use during the dry season. Existing gate plates 5 can block the water source of a river, causing the river to dry up. When the downstream... When daily water supply is required, the frequent opening and closing of the gate plate 5 is cumbersome. Therefore, an improvement is needed. Regularly arranged permeable channels 6 are created on the surface of the gate plate 5 to allow partial water flow, maintaining minimum downstream ecological water demand and preventing river flow interruption. The position of the sealing plate 11 is manually set according to demand. When a continuous, minimal downstream water supply is needed, the disassembly screw 13 is removed from the disassembly screw groove 12 located below the gate frame 1. Then, the sealing plate 11 is moved from one side of the gate plate 5 and moved above the gate plate 5. The disassembly screw 13 is then fixed into the disassembly screw groove 12 located above, ensuring that the sealing plate 11 does not block the permeable channels 6. The shielding net 7 is then fixed to the assembly screw 10. In the assembly of the screw channel 9, the shielding net 7 is installed on one side (the inlet end in the direction of water flow) of the multiple sets of permeable channels 6. The permeable channel 6 has an aperture of 1cm, and the shielding net 7 has an aperture of 2mm. This is used to shield sand, gravel, and small algae, preventing them from entering the permeable channel 6 and causing blockages that are difficult to clean. Even if blockage occurs on one side of the shielding net 7, it can be cleaned manually, which is convenient. This maintains a minimum ecological water demand downstream and avoids river flow interruption, which would require multiple adjustments to the position of the gate plate 5. At the same time, the assembly screw channel 9, assembly screw 10, disassembly screw channel 12, and disassembly screw 13 are all treated with anti-corrosion coating, which is a zinc-aluminum alloy coating. The sealing plate 11 and the shielding net 7 are both made of anti-corrosion stainless steel. The existing electric telescopic... When the lever 3 is damaged, and the opening of the gate plate 5 needs to be adjusted, it cannot be opened in an emergency. Therefore, an improvement is needed. When the electric telescopic lever 3 is damaged, the mounting screw 23 on the first upper mounting plate 18 is removed from the mounting screw groove 17 on the lower mounting plate 16, separating the first upper mounting plate 18 and the lower mounting plate 16. Then, the lower mounting plate 16 is rotated to remove the installation screw 15 from the installation screw groove 14. The lower mounting plate 16 is then moved below the rotating screw 20, and the lower mounting plate 16 is rotated to fix the installation screw 15 into the installation screw groove 14 on the other side. Then, the screw 20 is rotated to make the second upper mounting plate 22 and the lower mounting plate 16 fit together and be fixed into the mounting screw groove 17 by the mounting screw 23 for assembly.The outer shaft of bearing 21 is fixedly connected to the outer wall of the second upper mounting plate 22, and the inner shaft of bearing 21 is fixedly connected to the outer wall of the rotating screw 20. Therefore, when the rotating screw 20 is rotated, because the second upper mounting plate 22 and the lower mounting plate 16 are fixedly connected, the rotation of the inner shaft of bearing 21 will not cause the gate plate 5 to rotate. However, the rotating screw 20 rotates and moves within the rotating screw groove 19, causing the gate plate 5 to move up and down. This allows for adjustment of the gate plate 5's opening degree in emergency situations.
