Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy project treatment, and in particular to a water conservancy project flood prevention device and a flood prevention method. Background Art

[0002] A gate is a control device specially designed to open and close water flow channels. It is an indispensable part of hydraulic structures. It is widely used in scenarios such as intercepting water flow, regulating water levels, flexibly adjusting flow rates, and discharging sediment and floating objects. Especially in large-scale water conservancy facilities such as dams and reservoirs, gates play a key role in controlling water flow. In order to effectively prevent impurities such as garbage and aquatic plants carried in the water flow from flowing into downstream water bodies and causing environmental pollution, people usually add auxiliary facilities such as filter plates near the gates.

[0003] A flood control gate, method and system for a water conservancy project disclosed in a patent application with reference publication number CN119663805A includes two cement foundations of a water conservancy project, and an anti-blocking mechanism and a cleaning mechanism are provided on the two cement foundations of the water conservancy project. The anti-blocking mechanism includes a gate body arranged on the side where the two cement foundations of the water conservancy project are close to each other, and an electric gate is slidably installed on the front inner wall of the gate body. The tops of the two cement foundations of the water conservancy project are respectively provided with anti-blocking components. The electric gate is driven to rise and fall by a motor, and the meshing transmission of the teeth and gears and the combined design of the connecting rod mechanism are utilized to realize the automatic reciprocating motion of the cleaning bar on the sliding frame, which not only effectively removes impurities attached to the filter screen and prevents the filter screen from being blocked, but also greatly improves the efficiency and automation of the cleaning operation, eliminates the need for frequent manual intervention, reduces labor intensity, and also reduces the potential risks caused by filter screen blockage, ensuring unimpeded water flow.

[0004] During a flood, a large amount of garbage will be washed towards the gate. Therefore, a filter is often installed in front of the gate to intercept garbage and other items. However, as the amount of filtered objects increases, the impact on the filter becomes greater and greater, which will inevitably cause damage to the filter. During the process of intercepting garbage, the filter cannot be buffered and protected. In addition, the existing flood gate filter relies on manual intervention to clean when the intercepted objects accumulate, resulting in low efficiency and safety hazards. Traditional cleaning mechanisms lack an automated trigger mechanism and cannot respond to dynamic changes in the amount of garbage accumulation in real time.

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

[0025] 2. The gas inside the first airbag is squeezed into the second airbag through the vent tube. At this time, the expansion of the second airbag will push the locking seat to move outward.

[0026] 3. When the buffer plate moves, the first baffle indirectly blocks the flow slot, and water cannot pass through directly. Instead, it flows through the gap between the contact rod fixedly connected to one side of the first baffle and the buffer plate, thereby achieving a further buffering effect.

[0027] 4. The impeller drives the cleaning roller to rotate, so that the cleaning roller cleans the intercepting hole, and water flows to the nozzle through the water inlet pipe, and the nozzle sprays the intercepting hole for further cleaning. At the same time, during the rotation of the impeller, the fourth spring is driven to rotate, and the fourth spring squeezes the knocking plate to rotate, thereby knocking the intercepting plate. The cleaning roller rotates and cleans, and the water backwashes and knocking are coordinated to improve the overall cleaning effect. BRIEF DESCRIPTION OF THE DRAWINGS

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:

[0045] The intercepting plate 2 has an intercepting hole 201 for filtering on its surface, a guide groove 202 on its outer side, and a fixing frame 301 fixedly connected to both sides of the intercepting plate 2, a slider 200 fixedly connected to the bottom of the two fixing frames 301, a rising plate 3 is provided on the front side of the intercepting hole 201, and a driving member for rising the rising plate 3 is provided inside the fixing frame 301, and the driving member includes a reciprocating screw 303 provided inside one of the fixing frames 301, the reciprocating screw 303 passes through the rising plate 3 and is connected to the rising plate 3 by a ball nut pair, and a guide rod 302 is fixedly connected to the other fixing frame 301, the guide rod 302 passes through the rising plate 3 and is slidably connected to the rising plate 3, and a driving motor is fixedly connected to the top of the fixing frame 301, and the output shaft of the driving motor is fixedly connected to the reciprocating screw 303;

[0046] The toggle mechanism is arranged on the top of the rising plate 3. A connecting piece is provided inside the guide groove 202 of the intercepting plate 2, and a locking piece is provided on the outside of the toggle mechanism. When the toggle mechanism rises, the locking piece docks with the connecting piece, causing the toggle mechanism to move along the guide groove 202 toward both sides of the shore;

[0047] 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 outside of the guide slide bars 501 , and a buffer mechanism is provided between the two sliders 200 and the support seat 5 .

[0048] During specific implementation, 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, preparing for the next protection, and the buffer mechanism can be quickly reset.

[0049] In this embodiment: Figures 3 and 4As 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, and 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 the 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 outside of the fixing frame 406, and a first steel rope 404 is fixedly connected between the traction plate 407 and the two connecting plates 403 respectively.

[0050] During 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.

[0051] Example 2: Figures 5 and 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. The two guide seats 704 respectively pass through the sliding plate 703 and are slidably connected to the sliding plate 703.

[0052] The locking member includes a connecting cylinder 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 provided at the bottom of the connecting cylinder 601, a floating plate 6012 is slidably connected inside the connecting cylinder 601, a first air bag 6013 is fixedly connected between the floating plate 6012 and the top of the connecting cylinder 601, a fixed cylinder 602 is fixedly connected to the top of the toggle plate 401, a second air bag 6021 is provided inside the fixed cylinder 602, and one end of the second air bag 6021 is fixedly connected to the lock. The fixed seat 6023 and the locking seat 6023 pass through the fixed tube 602 and are slidably connected to the fixed tube 602. A second spring 6024 is sleeved on the outer side of the locking seat 6023. A ventilation tube 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.

[0053] 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. The water pushes the floating plate 6012 up inside the connecting tube 601 through the buoyancy force. 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. Move outward. Since one side of the locking seat 6023 is in contact with the intercepting 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 object, avoiding manual salvage, thereby improving overall efficiency.

[0054] Example 3: Figures 8 to 10 As shown, the buffer mechanism includes two buffer frames 8, which are respectively mounted 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 provided inside the buffer frame 8. The control switch 804 is electrically connected to the electric control valve 60141.

[0055] 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, and a push plate 805 is fixedly connected between the buffer plate 801 and the slider 200. The push plate 805 passes through 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.

[0056] In specific implementation, as the number of intercepted objects increases, the interception plate 2 is continuously pushed to move toward the support seat 5, so that the slider 200 pushes 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, and the control switch 804 is electrically connected to the drive motor to rotate the fixed frame 301, so that the rising plate 3 rises, thereby quantitatively processing the intercepted objects, and at the same time the control switch 804 is electrically connected to the electric control valve 60141 , delay control is adopted here. When the toggle plate 401 pushes the intercepted object to the shore, the electric control valve 60141 opens. 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 rising plate 3 descends, the intercepted object will appear between the toggle plates 401, making it impossible to clean.

[0057] At the same time, when the slider 200 pushes the buffer plate 801 to slide through the pushing plate 805, a water inlet hole 806 is opened on the outside of the buffer frame 8, and a large amount of water will fill 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 pushing 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 circulation groove 8011 as it is squeezed by the buffer plate 801, and the buffering effect is achieved through the flow of water.

[0058] In this embodiment, Figure 6 and Figure 9 As shown, a second steel rope 807 is fixedly connected between the buffer plate 801 and the sliding plate 703, a first baffle 8012 is provided on the side of the circulation groove 8011 close to the support seat 5, and a second baffle 8013 is provided on the other side of the circulation groove 8011, and a sliding rod is fixedly connected between the second baffle 8013 and the first baffle 8012, the sliding rod passes through the buffer plate 801 and is slidably connected to the buffer plate 801, and a contact rod 8014 is fixedly connected to one side of the first baffle 8012.

[0059] During specific implementation, a first baffle 8012 is provided on one side of the buffer plate 801. When the buffer plate 801 moves, the first baffle 8012 indirectly blocks the flow groove 8011. Water cannot pass through directly, but 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.

[0060] Example 4: Figures 6 and 7As shown, the outer side of the sliding plate 703 is fixedly connected to the fixed plate 701, and both ends of the fixed plate 701 are fixedly connected to the support plates 900. A cleaning roller 901 is rotatably connected between the two support plates 900. Both ends of the cleaning roller 901 are fixedly connected to the impeller 903. A mounting plate 902 is provided on the outer side of the impeller 903. The mounting plate 902 is connected to the buffer frame 8 through the liquid inlet pipe 908. A nozzle 909 is fixedly connected to one side of the two support plates 900, and a water inlet pipe is fixedly connected between the mounting plate 902 and the nozzle 909.

[0061] A knocking plate 905 is provided on one side of the mounting disk 902, and the knocking plate 905 is rotatably connected to the mounting disk 902 through a rotating shaft 907, and a fourth spring 906 is fixedly connected between one end of the knocking plate 905 and the mounting disk 902, and an extrusion plate 904 is fixedly connected to the outside of the cleaning roller 901, and the extrusion plate 904 is in contact with one end of the knocking plate 905.

[0062] In specific implementation, when the sliding plate 703 is rising, 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 relaxed state in a normal state. 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 is rising, the support plate 900 is driven to rise together through the fixed plate 701. The cleaning rollers 901 rotatably connected between the two support plates 900 rise together, and a mounting plate 902 is provided on one side of the support plate 900. Figure 7 The mounting plate 902 is closed. When the second steel rope 807 pulls the buffer plate 801 to move, the buffer plate 801 squeezes the water that has previously passed through the buffer plate 801, and the buffer frame 8 will automatically replenish the water through the water inlet hole 806, and the flow groove 8011 is closed by the second baffle 8013. At this time, the squeezed water enters the interior of the mounting plate 902 through the liquid inlet pipe 908, and drives the cleaning roller 901 to rotate through the impeller 903, so that the cleaning roller 901 cleans the interception hole 201, and the water flows to the nozzle 909 through the water inlet pipe, and the nozzle 909 sprays the interception hole 201 for further cleaning. At the same time, during the rotation of the impeller 903, it drives the fourth spring 906 to rotate, and the fourth spring 906 squeezes the knocking plate 905 to rotate, thereby knocking the interception plate 2. The cleaning roller 901 rotates to clean and the water is reversed and knocked, thereby improving the overall cleaning effect.

[0063] A flood prevention method for a water conservancy project is also provided, comprising the following steps:

[0064] Step 1: intercepting debris in the flood through the interception holes 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.

[0065] Step 2: The intercepting 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 intercepting plate 2. At this time, the toggle mechanism moves along the guide groove 202, pushing the garbage to both sides of the river channel.

[0066] Step 3: At the same time, the locking part drives the connecting part to move together, driving the buffer mechanism to automatically reset and prepare for the next protection.
