Description

Technical Field

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

[0002] Flood control projects are projects built to control and prevent floods in order to reduce flood losses. They mainly include embankments, river regulation projects, flood diversion projects and reservoirs. Flood control gates are now used in rivers to intercept the invasion of floods. When flood control is not needed, it may be necessary to intercept pollution, so most gates cannot block pollution when they are open. However, although existing gates are equipped with nets to block pollution, when a large amount of waste is accumulated at the nets, manual salvage is still required, which is very troublesome and not convenient enough. Patent documents have been issued to improve this.

[0003] For example, Chinese patent CN220977935U discloses a river channel flood prevention and pollution interception device, including a river channel body, a pollution interception frame disposed at the upper end of the river channel body, a barrier net and a pushing component for controlling the lifting of the barrier net disposed in the barrier net, a garbage collection bin detachably mounted at the lower end of the barrier net, a cleaning and brushing mechanism disposed at the upper end of the barrier net, connecting blocks fixedly mounted on both sides of the bottom of the barrier net, and two sets of rebound plugs inserted into the connecting blocks disposed at the bottom of the garbage collection bin. The river channel flood prevention and pollution interception device intercepts garbage in the river channel through a barrier net, and when it is necessary to clean the garbage, the garbage and other dirt on the barrier net are firstly cleaned into the garbage collection bin through the cleaning and brushing mechanism, and then the pushing component is controlled to move the barrier net and the garbage collection bin upward as a whole, and the garbage collection bin is quickly detached from the lower end of the barrier net through the rebound plugs on both sides, so that it is convenient for the staff to clean up the intercepted garbage, making cleaning more convenient and the device more applicable.

[0004] Although the equipment in the above documents can intercept garbage in the river, it still has obvious defects in actual use, such as: There is usually water flowing in the river channel, and when the equipment is used for cleaning, it is necessary to use the cleaning mechanism to sweep the garbage on the surface into the collection bin. However, water is fluid and has great buoyancy, and the garbage cannot be stably stored in the collection bin, resulting in the inability to take out the garbage after the barrier net rises. At the same time, the raised barrier net is located in the middle of the river channel, and the staff cannot clean it conveniently, making it too cumbersome and inconvenient to use. Therefore, a kind of river basin flood control device that can be easily cleaned is designed to solve this type of defect. Summary of the invention

[0012] Preferably, the pollution intercepting and cleaning mechanism includes an intercepting mesh plate, which is rotatably installed between two sides of the inner cavity of the river channel body through a rotating part, and the intercepting mesh plate is located at the front part of the gate body, and the lower part of the surface of the intercepting mesh plate is fixedly connected to a storage box, and the rear side of the top of the storage box is rotatably connected to a buoyancy baffle through an opening, and circular sockets for cooperating with a pressure cylinder are provided on the upper and lower parts of both sides of the surface of the storage box, and a pull-out baffle frame is provided on the inner side of the storage box, and both sides of the pull-out baffle frame are fixedly connected to a correction round seat.

[0013] Preferably, a retraction groove is provided on the surface of the pull-out baffle frame, and a second spring is fixedly connected to both sides of the rear part of the inner cavity of the retraction groove, and a double arc blocking plate used in conjunction with a storage box is fixedly connected to the front end of the second spring and located on the inner side of the retraction groove, and the lower parts of both sides of the rear part of the intercepting mesh plate are fixedly connected to convex guide rods used in conjunction with the limiting guide groove through brackets.

[0014] The present invention also discloses a river basin flood prevention method, which specifically comprises the following steps: S1. Before use, adjust the height of the gate body according to the flow of water inside the river channel. First, start the motor to drive the threaded rod to rotate slowly. When the threaded rod rotates, it will use the threaded ring to drive the gate body to rise and fall inside the U-shaped concave frame. When the height adjustment is completed, the motor stops starting; S2. When in use, water flows through the river body, and the water flows through the intercepting mesh plate and the U-shaped concave frame, and the gate body can block the water flow. Therefore, when the water flows, the internal debris is intercepted by the intercepting mesh plate, and then the cylinder is started to push the concave pressure frame down. At the same time, due to the elastic force of the first spring against the concave pressure frame, the concave pressure frame and the internal inner push plate are lowered. When the concave pressure frame descends, it will first cover the debris attached to the surface of the intercepting mesh plate inside and push it down. After the concave pressure frame descends to the bottom, the debris will squeeze the buoyancy baffle and push the buoyancy baffle toward the storage box. The inner side flips over until the concave pressure frame contacts the storage box and stops descending due to obstruction, but the cylinder will continue to descend and push the buffer guide rod. At this time, the buffer guide rod pushes the inner push plate down to push the debris into the inner side of the storage box for storage. After the debris is pushed in, the cylinder is started to pull the inner push plate up, and the buoyancy baffle will float up due to the buoyancy of the water and flip closely against the inner push plate to ensure that the debris inside the storage box will not float out of the storage box after the inner push plate rises. After the inner push plate is recovered to the inside of the concave pressure frame, the cylinder pulls the concave pressure frame up, and then repeats the descent to collect the debris. S3. When the intercepting mesh plate and the gate body need to be maintained, the motor is started to use the rotation of the threaded rod to continuously pull up the gate body. When the gate body is pulled upward, the two inclined surface retaining seats are synchronously driven to rise with the use of the slide cross bar. The rising of the inclined surface retaining seats separates the limiting guide groove from the convex guide rod. At this time, the intercepting mesh plate loses its limit. As the gate body drives the inclined surface retaining seats to continue to rise, the two inclined surface retaining seats are squeezed by the arc guide plate and move forward under the limiting action of the slide cross bar. The forward movement of the inclined surface retaining seats will push the intercepting mesh plate to flip upward until the gate body rises to the top and the intercepting mesh plate is completely The gate body is in a parallel state, and at the same time, the vertical sliding rod pushes the positioning rod out from the inner side of the positioning socket, and then pulls the U-shaped sliding frame to push the cylinder and the concave pressure frame forward. After the forward movement is completed, the starting cylinder pushes the concave pressure frame down again, and the concave pressure frame stops after contacting the material storage box. Then the inner push plate continues to descend until the pressure cylinder passes through the circular socket to press the double arc resistance plate, and presses the double arc resistance plate into the inner side of the retraction groove. At this time, the pull-out stop frame loses its limit, and then the pull-out stop frame is pushed out from the inner side of the material storage box and drives the internal debris to be discharged together, and then the gate body and the intercepting mesh plate are cleaned and maintained; S4. After the maintenance is completed, the pull-out baffle frame is pushed back into the inner side of the storage box. Since the pressing cylinder is still inserted into the inner side of the storage box, the double arc resistance plate can be pressed against the inner side of the retraction groove without being resisted. After the pull-out baffle frame is inserted into the storage box, the cylinder is started to drive the inner push plate and the concave pressure frame to rise and reset. Then the double arc resistance plate is pushed out under the elastic force of the second spring. The double arc resistance plate is engaged with the storage box to fix the pull-out baffle frame. After the cylinder has risen, the U-shaped slide is pulled to drive the cylinder to move backward and reset. Then the motor is started to drive the threaded rod to rotate Let the gate body descend, and after the gate body descends, it will no longer push up the vertical slide bar, let the positioning rod descend and insert into the inner side of the positioning hole to fix the U-shaped slide and the cylinder, at the same time, after the gate body descends, the inclined surface support seat is no longer squeezed by the arc guide plate, and the intercepting mesh plate uses its own weight to flip toward each other and push the inclined surface support seat to move backward and reset, until the inclined surface support seat moves completely backward, at this time the intercepting mesh plate is also in a vertical state, as the gate body drives the inclined surface support seat to descend, the limit guide groove also re-docking with the convex guide rod to fix the intercepting mesh plate.

[0015] The present invention provides a river basin flood control device and flood control method. Compared with the existing technology, it has the following beneficial effects: (1) The river basin flood control device and flood control method use a flood control gate mechanism and a pollution interception and cleaning mechanism in combination. The arrangement of these two mechanisms can first use the gate body to prevent floods on the river body, while the interception mesh plate intercepts and collects debris in the river. When the gate body and the interception mesh plate are subsequently cleaned, the linkage between the structures can be used to allow the gate body to unlock and flip the interception mesh plate after it rises, thereby facilitating the staff to clean it and improving practicality.

[0016] (2) The river basin flood control device and flood control method are characterized by installing a storage box on the surface of the intercepting mesh plate, and installing a pull-out baffle frame on the inner side of the storage box, and using it in conjunction with a concave pressure frame and an inner push plate. The arrangement of these structures can, while the intercepting mesh plate intercepts garbage, use the downward pressure of the concave pressure frame to push the garbage down, and then use the inner push plate to press the garbage into the inner side of the storage box. After the inner push plate rises, the buoyancy baffle can use the buoyancy to flip and always fit the inner push plate, thereby ensuring that the garbage inside the storage box will not use the buoyancy to spread again in the water, so that the garbage can be centrally processed during subsequent cleaning.

[0017] (3) The river basin flood control device and flood control method are characterized by installing two inclined seats on the rear part of the slide cross bar and using them in combination with a convex guide rod. The arrangement of these structures can fix the interception mesh plate by connecting the limit guide groove with the convex guide rod when the gate body intercepts the river water, thereby ensuring the stability of the interception mesh plate in daily interception of debris and garbage. After the gate body rises, the curved guide plate can be used to squeeze the inclined seat forward to push the interception mesh plate forward and flip it over, so that the interception mesh plate is in a horizontal state, which is convenient for the staff to clean the surface of the interception mesh plate and also convenient for the maintenance of the gate body, effectively improving the overall functionality of the equipment.

[0018] (4) The river basin flood control device and flood control method are used by opening a circular socket on the surface of the storage box, and matching it with a pressure cylinder and a double arc baffle plate. The arrangement of these structures can unlock the cylinder to facilitate pulling after the gate body rises and drives the interception mesh plate to flip. After pulling, the cylinder can be started again to insert the pressure cylinder into the circular socket to push the double arc baffle plate into the retraction groove to unlock the pull-out baffle frame, thereby facilitating the pull-out baffle frame. At the same time, the debris inside the storage box can also be quickly cleaned up, which meets the use in the current field. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The present invention also discloses a river basin flood prevention method, which specifically comprises the following steps: S1. Before use, the height of the gate body 104 is adjusted according to the flow of water inside the river channel body 101. First, the motor 110 is started to drive the threaded rod 111 to rotate slowly. When the threaded rod 111 rotates, it will use the threaded ring 112 to drive the gate body 104 to rise and fall inside the U-shaped concave frame 102. After the height adjustment is completed, the motor (110) is stopped. S2. When in use, water flows through the river channel body 101, and the water flows through the intercepting mesh plate 201 and the U-shaped concave frame 102, and the gate body 104 can block the water flow. Therefore, when the water flows, the internal debris is intercepted by the intercepting mesh plate 201, and then the cylinder 118 is started to push the concave pressing frame 120 down. At the same time, due to the elastic force of the first spring 122 against the concave pressing frame 120, the concave pressing frame 120 and the internal inner pushing plate 121 are lowered. When the concave pressing frame 120 descends, it will first cover the debris attached to the surface of the intercepting mesh plate 201 on the inside and push it down. After the concave pressing frame 120 drops to the bottom, the debris will squeeze the buoyancy baffle 203 and push the buoyancy baffle 203 into the storage box 202. After the inner push plate 121 is recovered to the inside of the concave press frame 120, the cylinder 118 pulls the concave press frame 120 to rise, and then repeats the descent to collect the debris; S3. When it is necessary to maintain the intercepting mesh plate 201 and the gate body 104, the starter motor 110 uses the rotation of the threaded rod 111 to continuously pull up the gate body 104. When the gate body 104 is pulled upward, the two inclined surface retaining seats 107 are synchronously driven to rise with the slide cross bar 106. The rise of the inclined surface retaining seats 107 separates the limiting guide groove 108 from the convex guide rod 210. At this time, the intercepting mesh plate 201 loses its limit. As the gate body 104 drives the inclined surface retaining seats 107 to continue to rise, the two inclined surface retaining seats 107 are squeezed by the arc guide plate 124 and move forward under the limiting action of the slide cross bar 106. The forward movement of the inclined surface retaining seats 107 will push the intercepting mesh plate 201 to flip upward until the gate body 104 rises to the top and the intercepting mesh plate 201 is completely in the The gate body 104 is in a parallel state, and at the same time, the gate body 104 will push the vertical sliding rod 116 to push the positioning plug rod 117 out of the inner side of the positioning plug hole 115, and then pull the U-shaped sliding frame 114 to push the cylinder 118 and the concave pressing frame 120 forward. After the forward movement is completed, the starting cylinder 118 pushes the concave pressing frame 120 down again, and the concave pressing frame 120 is blocked and stops after contacting the storage box 202. Then the inner pushing plate 121 continues to descend until the pressing cylinder 123 passes through the circular socket 204 and presses the double arc blocking plate 208, pressing the double arc blocking plate 208 into the inner side of the retraction groove 207. At this time, the pull-out blocking frame 205 loses its limit, and then the pull-out blocking frame 205 is pushed out from the inner side of the storage box 202 and drives the internal debris to be discharged together, and then the gate body 104 and the intercepting mesh plate 201 are cleaned and maintained; S4, after the maintenance is completed, the pull-out retaining frame 205 is pushed back into the inner side of the storage box 202. Since the pressing cylinder 123 is still inserted into the inner side of the storage box 202, the double arc blocking plate 208 can be pressed against the inner side of the retraction groove 207 without being resisted. After the pull-out retaining frame 205 is inserted into the storage box 202, the cylinder 118 is started to drive the inner pushing plate 121 and the concave pressing frame 120 to rise and reset. Subsequently, the double arc blocking plate 208 is pushed out under the elastic force of the second spring 209. The double arc blocking plate 208 is engaged with the storage box 202 to fix the pull-out retaining frame 205. After the cylinder 118 has risen, the U-shaped slide 114 is pulled to drive the cylinder 118 to move backward and reset. Then the motor 110 is started to drive the threaded rod 11 1 is rotated to make the gate body 104 descend, and after the gate body 104 descends, it no longer pushes the vertical slide bar 116, allowing the positioning rod 117 to descend and insert into the inner side of the positioning plug hole 115 to fix the U-shaped slide 114 and the cylinder 118. At the same time, after the gate body 104 descends, the inclined surface support 107 is no longer squeezed by the arc guide plate 124, and the interception mesh plate 201 uses its own weight to flip towards each other and push the inclined surface support 107 to move backward and reset until the inclined surface support 107 is completely moved backward. At this time, the interception mesh plate 201 is also in a vertical state. As the gate body 104 drives the inclined surface support 107 to descend, the limiting guide groove 108 also re-docking with the convex guide rod 210 to fix the interception mesh plate 201.

9. A method for flood control in a river basin, characterized in that: The specific steps include: S1. Before use, the height of the gate body (104) is adjusted according to the flow rate of water inside the river channel body (101). First, the motor (110) is started to drive the threaded rod (111) to rotate slowly. When the threaded rod (111) rotates, it drives the gate body (104) to rise and fall inside the U-shaped concave frame (102) by means of the threaded ring tube (112). When the height adjustment is completed, the motor (110) is stopped. S2. When in use, water flows through the river channel body (101), and the water flows through the intercepting mesh plate (201) and the U-shaped concave frame (102), and the gate body (104) can block the water flow. Therefore, when the water flows, the internal debris is intercepted by the intercepting mesh plate (201), and then the cylinder (118) is started to push the concave pressing frame (120) down. At the same time, due to the elastic force of the first spring (122) against the concave pressing frame (120), the concave pressing frame (120) and the internal pushing plate (121) are lowered. When the concave pressing frame (120) descends, it will first cover the debris attached to the surface of the intercepting mesh plate (201) inside and push it down. After the concave pressing frame (120) descends to the bottom, the debris will squeeze the buoyancy baffle (203) and push the buoyancy baffle (203) to the inside of the storage box (202). The concave pressing frame (120) is turned over until it contacts the material storage box (202) and is blocked and stops descending, but the cylinder (118) continues to descend and pushes the buffer guide rod (119). At this time, the buffer guide rod (119) pushes the inner push plate (121) to descend and pushes the debris into the inner side of the material storage box (202) for storage. After the pushing of the debris is completed, the cylinder (118) is started to pull the inner push plate (121) up, and the buoyancy baffle (203) floats up due to the buoyancy of the water and turns over closely to the inner push plate (121), ensuring that the debris inside the material storage box (202) will not float out of the material storage box (202) after the inner push plate (121) rises. After the inner push plate (121) is recovered to the inside of the concave pressing frame (120), the cylinder (118) pulls the concave pressing frame (120) to rise, and then repeatedly descends to collect the debris. S3, when it is necessary to maintain the intercepting mesh plate (201) and the gate body (104), the motor (110) is started to continuously pull up the gate body (104) by rotating the threaded rod (111), and when the gate body (104) is pulled upward, the two inclined surface retaining seats (107) are synchronously driven to rise by the slide cross bar (106), and the inclined surface retaining seats (107) rise so that the limiting guide groove (108) and the convex guide rod (210) are aligned. The intercepting mesh plate (201) loses its limit position, and as the gate body (104) drives the inclined surface retaining seat (107) to continue to rise, the two inclined surface retaining seats (107) are squeezed by the arc guide plate (124) and move forward under the limit position of the slide cross bar (106), and the forward movement of the inclined surface retaining seat (107) pushes the intercepting mesh plate (201) to flip upward until the gate body (104) rises to the top and the intercepting mesh plate (201) is completely flat. The gate body (104) is in a state of movement, and at the same time, the gate body (104) will push the vertical slide bar (116) to push the positioning rod (117) out from the inner side of the positioning socket (115), and then pull the U-shaped slide (114) to push the cylinder (118) and the concave pressing frame (120) forward. After the forward movement is completed, the cylinder (118) is started to push the concave pressing frame (120) down again, and the concave pressing frame (120) is blocked and stops after contacting the material storage box (202), and then the inner push plate ( 121) continues to descend until the pressing cylinder (123) passes through the circular socket (204) and presses the double arc blocking plate (208), pressing the double arc blocking plate (208) into the inner side of the retraction groove (207), at which time the pull-out blocking frame (205) loses its limit, and then the pull-out blocking frame (205) is pushed out from the inner side of the storage box (202) and the internal debris is discharged together, and then the gate body (104) and the intercepting mesh plate (201) are cleaned and maintained; S4, after the maintenance is completed, the pull-out stop frame (205) is pushed back into the inner side of the storage box (202). Since the pressing cylinder (123) is still inserted into the inner side of the storage box (202), the double arc blocking plate (208) can be pressed against the inner side of the retraction groove (207) without being interfered with. After the pull-out stop frame (205) is inserted into the storage box (202), the cylinder (118) is started to drive the inner push plate (121) and the concave pressure frame (120) to rise and reset. Subsequently, the double arc blocking plate (208) is pushed out under the elastic force of the second spring (209). The double arc blocking plate (208) is engaged with the storage box (202) to fix the pull-out stop frame (205). After the cylinder (118) has risen, the U-shaped slide (114) is pulled to drive the cylinder (118) to move backward and reset. Then, the motor (110) is started to drive the threaded rod (1 11) Rotation allows the gate body (104) to descend, and after the gate body (104) descends, it no longer pushes the vertical slide bar (116), allowing the positioning rod (117) to descend and insert into the inner side of the positioning hole (115) to fix the U-shaped slide (114) and the cylinder (118). At the same time, after the gate body (104) descends, the inclined surface support seat (107) is no longer squeezed by the arc guide plate (124), and the interception mesh plate (201) uses its own weight to flip toward each other and push the inclined surface support seat (107) to move backward and reset until the inclined surface support seat (107) is completely moved backward. At this time, the interception mesh plate (201) is also in a vertical state. As the gate body (104) drives the inclined surface support seat (107) to descend, the limiting guide groove (108) is also re-connected with the convex guide rod (210) to fix the interception mesh plate (201) to limit.
