Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy project treatment, and particularly relates to a flood control device and a flood control method for water conservancy projects. Background Art

[0002] A gate is a control device specifically designed to open and close a water flow channel and constitutes an essential part of a hydraulic structure. It is widely used in scenarios such as intercepting water flow, regulating water level, flexibly adjusting flow rate, and discharging sediment and floating objects. Especially in large water conservancy facilities such as dams and reservoirs, the gate plays a key role in controlling water flow. In order to effectively prevent impurities such as garbage and waterweeds carried in the water flow from flowing into the downstream water body and causing environmental pollution, an auxiliary facility of a filter plate is usually added near the gate.

[0003] A flood control gate, method, and system for a water conservancy project disclosed in a patent application with a reference publication number of CN119663805A includes two gate cement bases. An anti-blocking mechanism and a cleaning mechanism are arranged on the two gate cement bases. The anti-blocking mechanism includes a gate body arranged on one side where the two gate cement bases are close to each other. An electric gate is slidably installed on the inner wall of the front surface of the gate body. Anti-blocking components are respectively arranged on the tops of the two gate cement bases. By driving the electric gate to lift through a motor, using the meshing transmission of a tooth groove and a gear, and the combined design of a link mechanism, the automatic reciprocating movement of a cleaning strip on a sliding frame is realized. It not only effectively removes impurities attached to the filter screen, prevents the blockage of the filter screen, but also greatly improves the efficiency and automation degree of the cleaning operation, eliminates the need for frequent manual intervention, reduces the labor intensity, and at the same time reduces the potential risks caused by the blockage of the filter screen, ensuring unobstructed water flow.

[0004] During the flood process, a large amount of garbage will be washed towards the gate by the flood. Therefore, a filter screen is often arranged in front of the gate to intercept garbage and other items. However, as the amount of intercepted objects increases, the impact on the filter screen becomes greater, which will inevitably damage the filter screen. During the interception of garbage, the filter screen cannot be buffered and protected, and the existing flood control gate filter screen relies on manual intervention for cleaning when the intercepted objects accumulate, resulting in low efficiency and potential safety hazards. The traditional cleaning mechanism lacks an automatic triggering mechanism and cannot respond in real time to the dynamic changes in the garbage accumulation amount.

[0005] Therefore, it is necessary to provide a flood control device and a flood control method for water conservancy projects to solve the above technical problems. Summary of the Invention

The first screw rod 103 passes through the mounting frame 101 and is rotatably connected to the mounting frame 101. The first screw rod 103 is driven to rotate by an external motor, thereby driving the gate 102 to rise and fall. It also includes: An intercepting plate 2, with an intercepting hole 201 for filtering provided on the surface of the intercepting plate 2, a guide groove 202 provided on the outer side of the intercepting plate 2, and fixed frames 301 fixedly connected on both sides of the intercepting plate 2, sliders 200 fixedly connected on the bottoms of the two fixed frames 301, a rising plate 3 provided on the front side of the intercepting hole 201, a driving member for rising the rising plate 3 provided inside the fixed frame 301, the driving member comprising a reciprocating screw 303 provided inside one of the fixed frames 301, the reciprocating screw 303 penetrates the rising plate 3 and is connected to the rising plate 3 through a ball nut pair, a guide rod 302 fixedly connected inside the other fixed frame 301, the guide rod 302 penetrates the rising plate 3 and is slidably connected to the rising plate 3, a driving motor fixedly connected to the top of the fixed frame 301, and the output shaft of the driving motor is fixedly connected to the reciprocating screw 303; The toggle mechanism is arranged on the top of the rising plate 3, a connecting piece is arranged inside the guide groove 202 of the intercepting plate 2, and a locking piece is arranged outside the toggle mechanism. When the toggle mechanism rises, the locking piece docks with the connecting piece, so that the toggle mechanism moves along the guide groove 202 to both sides of the shore; The support seat 5 has two guide slide bars 501 fixedly connected to one side of the support seat 5 , and the two sliders 200 are respectively slidably connected to the outer sides of the guide slide bars 501 , and a buffer mechanism is provided between the two sliders 200 and the support seat 5 .

[0027] During specific implementation, the debris in the flood is intercepted through the interception hole 201 on the interception plate 2. As the amount of debris increases, the interception plate 2 is pushed to slide along the guide slide bar 501; the interception plate 2 is protected from sliding by the buffer mechanism on the guide slide bar 501, and the rising plate 3 is driven to rise by the driving member. When the rising plate 3 reaches a certain height, the connecting member on the toggle mechanism docks with the locking member inside the guide groove 202 on the interception plate 2. At this time, the toggle mechanism moves along the guide groove 202 to move the garbage to both sides of the river channel; at the same time, as the locking member drives the connecting member to move together, the buffer mechanism is driven to automatically reset, and preparation for the next protection is made, and the buffer mechanism can be quickly reset.

[0028] In this embodiment: Figures 3 to 4 As shown, the toggle mechanism includes two toggle plates 401, and grooves are provided on opposite sides of the two toggle plates 401. A first spring 402 is provided inside the groove, one end of the first spring 402 is fixedly connected to the toggle plate 401, and the other end of the first spring 402 is fixedly connected to a connecting plate 403. A guide roller 405 is provided inside the groove, and the guide roller 405 is rotatably connected to the toggle plate 401. A fixing frame 406 is fixedly connected to the top of the rising plate 3, and the fixing frame 406 passes through the two toggle plates 401 and is slidably connected to the toggle plates 401. A traction plate 407 is fixedly connected to the outer side of the fixing frame 406, and the traction plate 407 is fixedly connected to the first steel rope 404 between the two connecting plates 403.

[0029] In specific implementation, when the rising plate 3 drives the toggle mechanism to rise, as the connecting piece and the locking piece are docked, the two toggle plates 401 are separated along the guide groove 202 respectively, and the interception object on the top of the rising plate 3 is pushed to both sides. When the rising plate 3 moves to the height of the river bank, the interception object pushes both sides of the river bank to prevent the interception object from moving downstream with the water and accumulating in the river section to cause the water level to rise. The interception object can be automatically pushed to the river bank, avoiding manual salvage.

[0030] Embodiment 2: Figures 5 to 6 and Figure 11 As shown, the connecting member includes a sliding plate 703 arranged on one side of the intercepting plate 2, and two connecting seats 702 are slidably connected to the outer side of the sliding plate 703. The two connecting seats 702 extend to the inside of the two guide grooves 202 respectively and are slidably connected to the intercepting plate 2. The outer sides of the two fixed frames 301 are fixedly connected with guide seats 704, and the two guide seats 704 respectively penetrate the sliding plate 703 and are slidably connected to the sliding plate 703.

[0031] The locking member includes a connecting tube 601 fixedly connected to one side of the toggle plate 401, a one-way water inlet valve 6014 and an electric control valve 60141 are arranged at the bottom of the connecting tube 601, a floating plate 6012 is slidably connected inside the connecting tube 601, a first air bag 6013 is fixedly connected between the floating plate 6012 and the top of the connecting tube 601, a fixed tube 602 is fixedly connected to the top of the toggle plate 401, a second air bag 6021 is arranged inside the fixed tube 602, and a lock is fixedly connected to one end of the second air bag 6021 The fixed seat 6023 and the locking seat 6023 penetrate the fixed tube 602 and are slidably connected with the fixed tube 602. A second spring 6024 is sleeved on the outer side of the locking seat 6023. A ventilation pipe 6022 is fixedly connected between the second airbag 6021 and the first airbag 6013. When the floating plate 6012 rises due to the buoyancy, the first airbag 6013 is squeezed, so that the second airbag 6021 pushes the locking seat 6023 to move to the side of the intercepting plate 2, and the locking seat 6023 is adapted to the connecting seat 702.

[0032] In a specific implementation, when the connecting tube 601 on the toggle plate 401 is underwater, water is fed in one direction through the one-way water inlet valve 6014, and the water pushes the floating plate 6012 to rise inside the connecting tube 601 through the buoyancy. After the floating plate 6012 rises, it squeezes the first airbag 6013. When the first airbag 6013 is squeezed, the gas inside the first airbag 6013 is squeezed into the second airbag 6021 through the vent pipe 6022. At this time, the expansion of the second airbag 6021 pushes the locking seat 6023 Moving outward, since one side of the locking seat 6023 is in contact with the interception hole 201 during the rising process of the rising plate 3, only when it reaches the connecting seat 702, the second airbag 6021 continues to push the locking seat 6023 to quickly insert into the connecting seat 702. At this time, the locking seat 6023 drives the connecting seat 702 to rise together through the connecting seat 702, and drives the sliding plate 703 to rise as a whole, so that the two toggle plates 401 automatically push the intercepted objects to avoid manual salvage, thereby improving the overall efficiency.

[0033] Embodiment 3: Figures 8 to 10 As shown, the buffer mechanism includes two buffer frames 8, which are respectively sleeved on the outside of the guide slide rod 501 and fixedly connected to the support seat 5. A water inlet hole 806 connected to the outside is opened on the outside of the buffer frame 8, and a control switch 804 is arranged inside the buffer frame 8. The control switch 804 is electrically connected to the electric control valve 60141.

[0034] The buffer mechanism also includes a buffer plate 801 arranged inside the buffer frame 8, the buffer plate 801 is slidably connected to the outside of the guide slide rod 501, and a third spring 803 is fixedly connected between the buffer plate 801 and one end inside the buffer frame 8, a push plate 805 is fixedly connected between the buffer plate 801 and the slider 200, the push plate 805 penetrates the buffer frame 8 and is slidably connected to the buffer frame 8, and when the buffer plate 801 moves, it drives the push plate 805 to seal the water inlet hole 806, and a plurality of flow grooves 8011 are opened on the outside of the buffer plate 801.

[0035] In specific implementation, as the number of intercepted objects increases, the interception plate 2 is continuously pushed towards the support base 5, causing the slider 200 to push the buffer plate 801 to slide inside the buffer frame 8 through the fixedly connected push plate 805. When the maximum buffering degree is reached, the buffer plate 801 contacts the control switch 804. Through the electrical connection between the control switch 804 and the drive motor, the fixed frame 301 rotates, so that the lifting plate 3 rises, thereby quantitatively processing the intercepted objects. At the same time, the control switch 804 is electrically connected to the electric control valve 60141. Here, delay control is adopted. After the toggle plate 401 pushes the intercepted objects to the shore, the electric control valve 60141 is opened. At this time, the water inside the connecting cylinder 601 flows out, the floating plate 6012 descends, and the second spring 6024 pushes the locking seat 6023 to slide into the fixed cylinder 602, separating from the connecting seat 702. At the same time, under the action of the first spring 402 inside the toggle plate 401, the two toggle plates 401 quickly merge, and after the lifting plate 3 descends, the intercepted objects will appear between the toggle plates 401, resulting in a situation where they cannot be cleaned up.

[0036] At the same time, when the slider 200 pushes the buffer plate 801 to slide through the push plate 805, a water inlet hole 806 is opened on the outer side of the buffer frame 8. A large amount of water will fill the space between the buffer plate 801 and one end inside the buffer frame 8. When the buffer plate 801 moves, the water inside the buffer frame 8 will block the buffer plate 801, and the push plate 805 on one side of the buffer plate 801 will seal the water inlet hole 806 as it moves. At this time, the water will flow to the other side of the buffer plate 801 through the flow channel 8011 under the extrusion of the buffer plate 801, achieving the buffering effect through the flow of water.

[0037] In this embodiment, as Figure 6 and Figure 9 shown, a second steel wire rope 807 is fixedly connected between the buffer plate 801 and the sliding plate 703. A first baffle 8012 is arranged on one side of the flow channel 8011 close to the support base 5, and a second baffle 8013 is arranged on the other side of the flow channel 8011. A slide bar is fixedly connected between the second baffle 8013 and the first baffle 8012. The slide bar penetrates through the buffer plate 801 and is slidably connected to the buffer plate 801. A contact rod 8014 is fixedly connected to one side of the first baffle 8012.

[0038] In specific implementation, a first baffle 8012 is arranged on one side of the buffer plate 801. When the buffer plate 801 moves, the first baffle 8012 indirectly blocks the flow channel 8011, and the water cannot directly pass through. Instead, it flows through the buffer plate 801 through the gap between the contact rod 8014 fixedly connected to one side of the first baffle 8012 and the buffer plate 801, thereby achieving a further buffering effect.

[0039] Embodiment 4: As Figures 6 to 7As shown in the figure, a fixed plate 701 is fixedly connected to the outside of the sliding plate 703. Both ends of the fixed plate 701 are fixedly connected with support plates 900. A cleaning roller 901 is rotatably connected between the two support plates 900. Impellers 903 are fixedly connected to both ends of the cleaning roller 901. An installation disk 902 is arranged outside the impellers 903. The installation disk 902 is connected to the buffer frame 8 through a liquid inlet pipe 908. Nozzles 909 are fixedly connected to one side of the two support plates 900. A water inlet pipe is fixedly connected and communicated between the installation disk 902 and the nozzles 909.

[0040] A knocking plate 905 is arranged on one side of the installation disk 902. The knocking plate 905 is rotatably connected to the installation disk 902 through a rotating shaft 907. A fourth spring 906 is fixedly connected between one end of the knocking plate 905 and the installation disk 902. An extrusion plate 904 is fixedly connected to the outside of the cleaning roller 901. One end of the extrusion plate 904 is in contact with the knocking plate 905.

[0041] During specific implementation, when the sliding plate 703 rises, the buffer plate 801 is pulled by the second steel rope 807 to move inside the buffer frame 8. The second steel rope 807 is in a slack state under normal conditions. Only when the buffer plate 801 moves to the control switch 804, the second steel rope 807 is in a taut state. When the sliding plate 703 rises, the support plates 900 are driven to rise together through the fixed plate 701. The cleaning roller 901 rotatably connected between the two support plates 900 rises together. And an installation disk 902 is arranged on one side of the support plates 900. Figure 7 The installation disk 902 in [description] is closed. When the second steel rope 807 pulls the buffer plate 801 to move, the buffer plate 801 squeezes the water that passed through the buffer plate 801 before. And the water in the buffer frame 8 will be automatically replenished through the water inlet hole 806. The flow channel 8011 is closed by the second baffle 8013. At this time, the squeezed water is introduced into the installation disk 902 through the liquid inlet pipe 908. The cleaning roller 901 is driven to rotate through the impeller 903, so that the cleaning roller 901 cleans the intercepting holes 201. And the water flows to the nozzles 909 through the water inlet pipe. The nozzles 909 spray the intercepting holes 201, so as to further clean. At the same time, during the rotation of the impeller 903, the fourth spring 906 is driven to rotate. The fourth spring 906 squeezes the knocking plate 905 to rotate, so as to knock the intercepting plate 2. Through the rotation cleaning of the cleaning roller 901, the reverse flushing of water and the knocking cooperation, the overall cleaning effect is improved.

[0042] A flood control method for water conservancy projects is also provided, including the following steps: Step 1: Debris in the flood is intercepted through the intercepting holes 201 on the intercepting plate 2.
