Description

Technical Field

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

[0002] Flood control projects are projects built to control and defend floods to reduce flood losses, mainly including levees, river regulation projects, flood diversion projects, and reservoirs, etc. Flood control gates are now used in rivers to intercept the intrusion of floods. When flood control is not required, it may also be necessary to intercept pollutants. Therefore, most gates cannot intercept when they are in the open state. Although the existing gates are equipped with a net to block, when a large amount of waste accumulates at the net, manual fishing is still required, which is very troublesome and the handling is not convenient enough. There have been patent documents to improve this situation.

[0003] Such as Chinese Patent CN220977935U, a river flood control and pollution interception device, including a river main body, a pollution interception frame is arranged at the upper end of the river main body, a net is arranged inside the pollution interception frame and a pushing component for controlling the lifting of the net, a garbage collection bin is detachably installed at the lower end of the net, a cleaning mechanism is arranged at the upper end of the net, both sides of the bottom of the net are fixedly installed with connecting blocks, and two groups of spring-back plugins inserted into the connecting blocks are arranged at the bottom of the garbage collection bin. This river flood control and pollution interception device intercepts the garbage in the river through the net. When it is necessary to clean the garbage, first, the cleaning mechanism sweeps the garbage and other dirt on the net into the garbage collection bin, and then controls the pushing component to move the net and the garbage collection bin upward as a whole, and the garbage collection bin is quickly detached from the lower end of the net through the spring-back plugins on both sides, so as to facilitate the staff to clean the intercepted garbage, making the cleaning more convenient and the device more applicable.

[0004] Although the equipment in the above document can intercept the garbage in the river, it still has obvious defects in actual use, such as:

[0005] There is usually water flowing in the river. When this equipment is cleaned, it is necessary to use the cleaning mechanism to sweep the garbage on the surface into the interior of the collection bin. However, water is fluid and has a large buoyancy, and the garbage cannot be stably stored in the interior of the collection bin, resulting in the inability to take out the garbage after the net rises. At the same time, the net after rising is located in the middle of the river, and it is inconvenient for the staff to clean it. The whole use is too cumbersome and inconvenient;

[0006] Therefore, a river basin flood control device that can be conveniently cleaned is now designed to solve such defects. Summary of the Invention

[0012] Preferably, sliding sleeve rings are fixedly connected to both sides of the surface of the curved door frame through fixing blocks. A vertical sliding rod is slidably installed inside the sliding sleeve ring. The top end of the vertical sliding rod is fixedly connected to a positioning insertion rod through a fixing plate, and the positioning insertion rod is located inside the positioning jack. Arc-shaped guide plates for matching use with the slanting abutting seats are fixedly connected to the upper parts of both sides of the inner cavity of the river channel body and behind the gate body through brackets.

[0013] Preferably, a buffer guide rod is fixedly connected to the bottom end of the cylinder through a fixing plate. A concave pressing frame is slidably installed on the surface of the buffer guide rod. An inner pushing plate is fixedly connected to the bottom end of the buffer guide rod and inside the concave pressing frame. A first spring is sleeved on the surface of the buffer guide rod and above the concave pressing frame. Pressing cylinders are fixedly connected to the front and rear parts of both sides of the bottom of the inner pushing plate.

[0014] Preferably, the trash interception and cleaning mechanism includes an interception net plate, which is rotatably installed between the two sides of the inner cavity of the river channel body through a rotating member, and the interception net plate is located in front of the gate body. A storage box is fixedly connected to the lower part of the surface of the interception net plate. The rear side of the top of the storage box is rotatably connected with a buoyancy baffle through an opening. Circular sockets for cooperating with the pressing cylinders are respectively arranged at the upper and lower parts on both sides of the surface of the storage box. A drawable stop frame is arranged inside the storage box, and correction circular seats are fixedly connected to both sides of the drawable stop frame.

[0015] Preferably, a retraction groove is formed on the surface of the drawable stop frame. Second springs are fixedly connected to both sides of the rear part of the inner cavity of the retraction groove. The front ends of the second springs and located inside the retraction groove are fixedly connected with double-arc stop plates for cooperating with the storage box. Convex guide rods for cooperating with the limit guide grooves are fixedly connected to the lower parts of both sides of the rear part of the interception net plate through brackets.

[0016] The present invention also discloses a flood control method for a river basin, which specifically includes the following steps:

[0017] S1. Before use, adjust the height of the gate body according to the water flow inside the river channel body. First, start the motor to drive the threaded rod to slowly rotate. When the threaded rod rotates, it will use the threaded ring cylinder to drive the gate body to lift and lower inside the U-shaped concave frame. After the height adjustment is completed, the motor stops starting.

[0018] S2. During use, the water flows through the river channel body, and the water flow passes through the interception net plate and the U-shaped concave frame. The gate body can block the water flow. Therefore, the sundries inside the water are intercepted by the interception net plate when flowing. Then, start the air cylinder to push the concave pressing frame to descend. At the same time, due to the elastic force of the first spring against the concave pressing frame, the concave pressing frame and the inner pushing plate inside it descend. When the concave pressing frame descends, it will first cover the sundries sticking to the surface of the interception net plate inside and push them downward. After the concave pressing frame descends to the bottom, the sundries will squeeze the buoyancy baffle and push the buoyancy baffle to turn towards the inside of the storage box until the concave pressing frame touches the storage box and is blocked from descending. However, the air cylinder will continue to descend and push the buffer guide rod. At this time, the buffer guide rod pushes the inner pushing plate to descend to push the sundries into the inside of the storage box for storage. After the sundries are pushed in, start the air cylinder to pull the inner pushing plate to rise. The buoyancy baffle will float due to the buoyancy of the water and turn closely against the inner pushing plate to ensure that the sundries inside the storage box will not float out of the storage box after the inner pushing plate rises. After the inner pushing plate is retracted into the concave pressing frame, the air cylinder then pulls the concave pressing frame to rise, and then repeat the descending to collect the sundries.

[0019] S3. When the intercepting mesh plate and the gate body need to be maintained, the motor is started and the gate body is continuously pulled up by rotating the threaded rod. When the gate body is pulled up, the two inclined surface retaining seats are synchronously driven to rise by the slide cross bar. The rising of the inclined surface retaining seats causes the limiting guide groove to separate 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 closed. When the gate is fully parallel, the vertical sliding rod will push the positioning rod out from the inner side of the positioning socket, and then the U-shaped slide will be pulled to push the cylinder and the concave pressure frame forward. After the forward movement is completed, the cylinder will be started to push the concave pressure frame down again. After the concave pressure frame contacts the storage box, it will be blocked and stop. Then the inner push plate will continue to descend until the pressure cylinder passes through the circular socket and presses the double arc resistance plate, pressing 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 storage box and drives the internal debris to be discharged together. Then the gate body and the intercepting mesh plate are cleaned and maintained.

[0020] S4. After the maintenance is completed, the pull-out retaining 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 retaining frame is inserted into the interior of 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 and the storage box are engaged to fix the pull-out retaining frame. After the cylinder has finished rising, the U-shaped slide is pulled to drive the cylinder to move back and reset, and then the motor is started to drive the threaded rod to rotate Let the gate body drop down, and after the gate body drops down, it will no longer push up the vertical slide bar, let the positioning rod drop down and insert into the inner side of the positioning socket to fix the U-shaped slide and the cylinder. At the same time, after the gate body drops down, 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 drop, the limit guide groove also re-docking with the convex guide rod to fix the intercepting mesh plate.

[0021] The present invention provides a river basin flood control device and method. Compared with existing technologies, it has the following advantages:

[0022] (1) The flood control device and method for the river basin combine the flood control gate mechanism and the trash interception and cleaning mechanism. The settings of these two mechanisms can first use the gate body to carry out flood control on the river body, while the interception net plate intercepts and collects the sundries in the river. And when cleaning the gate body and the interception net plate subsequently, the linkage between the structures can be used to unlock and flip the interception net plate after the gate body rises, thus facilitating the staff to clean it and improving the practicability.

[0023] (2) The flood control device and method for the river basin are used in combination with a storage box installed on the surface of the interception net plate and a pull-out retaining frame installed inside the storage box, along with a concave pressing frame and an inner pushing plate. The settings of these structures can, while the interception net plate intercepts garbage, use the downward pressure of the concave pressing frame to push the garbage downward, and then use the inner pushing plate to press the garbage into the inside of the storage box. And after the inner pushing plate rises subsequently, the buoyancy baffle can use buoyancy to flip and always fit with the inner pushing plate, so as to ensure that the garbage inside the storage box will not spread in the water again using buoyancy, facilitating centralized treatment of the garbage when cleaning subsequently.

[0024] (3) The flood control device and method for the river basin are used in combination with two inclined surface abutments installed at the rear part using a sliding frame cross bar, along with a convex guide rod. The settings of these structures can, when the gate body intercepts river water, fix the interception net plate by docking the limit guide groove with the convex guide rod, ensuring the stability of the interception net plate for daily interception of sundries and garbage. And after the gate body rises subsequently, the arc-shaped guide plate can also be used to squeeze the inclined surface abutment to move forward and push the interception net plate forward and flip it, making the interception net plate in a horizontal state, facilitating the staff to clean the surface of the interception net plate and also facilitating the maintenance of the gate body, effectively improving the overall functionality of the equipment.

[0025] (4) The flood control device and method for the river basin are used in combination with a circular socket opened on the surface of the storage box, along with a pressing cylinder and a double-arc blocking plate. The settings of these structures can, after the gate body rises to drive the interception net plate to flip and unlock the cylinder for easy pulling, and when the pulled cylinder is started again, it can use the pressing cylinder to insert into the circular socket to push the double-arc blocking plate into the retraction groove to unlock the pull-out retaining frame, thus facilitating the pulling of the pull-out retaining frame and also quickly cleaning the sundries inside the storage box, meeting the usage in the current field.

[0041] The present invention also discloses a flood control method for a river basin, which specifically includes the following steps:

[0042] S1. Before use, adjust the height of the gate body 104 according to the water flow in the river channel body 101. First, start the motor 110 to drive the threaded rod 111 to slowly rotate. When the threaded rod 111 rotates, it will use the threaded ring cylinder 112 to drive the gate body 104 to lift and lower inside the U-shaped concave frame 102. After the height adjustment is completed, the motor (110) stops starting;

[0043] S2. During use, water flows through the river channel body 101, and the water passes through the intercepting net plate 201 and the U-shaped concave frame 102. The gate body 104 can block the water flow. Therefore, the sundries inside the water are intercepted by the intercepting net plate 201. Then, the air cylinder 118 is started to push the concave pressing frame 120 downward. 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 inner pushing plate 121 inside it descend. When the concave pressing frame 120 descends, it will first enclose the sundries sticking to the surface of the intercepting net plate 201 inside and push them downward. After the concave pressing frame 120 descends to the bottom, the sundries will squeeze the buoyancy baffle 203 and push the buoyancy baffle 203 to turn inward towards the storage box 202 until the concave pressing frame 120 touches the storage box 202 and is blocked from descending further. However, the air cylinder 118 will continue to descend and push the buffer guide rod 119. At this time, the buffer guide rod 119 pushes the inner pushing plate 121 downward to push the sundries into the inside of the storage box 202 for storage. After the sundries are pushed in, the air cylinder 118 is started to pull the inner pushing plate 121 upward. The buoyancy baffle 203 floats upward due to the buoyancy of the water and turns closely against the inner pushing plate 121, ensuring that the sundries inside the storage box 202 will not float out of the storage box 202 after the inner pushing plate 121 rises. After the inner pushing plate 121 is retracted into the concave pressing frame 120, the air cylinder 118 then pulls the concave pressing frame 120 upward, and then repeats the downward movement to collect the sundries;

[0044] S3. When maintenance is required for the interception net plate 201 and the gate body 104, start the motor 110 to continuously pull up the gate body 104 by rotating the threaded rod 111. When the gate body 104 is pulled upward, it will synchronously drive the two inclined surface seats 107 to rise along with the carriage cross bar 106. When the inclined surface seats 107 rise, the limit guide groove 108 is separated from the convex guide rod 210. At this time, the interception net plate 201 loses its limit. As the gate body 104 continues to rise with the inclined surface seats 107, the two inclined surface seats 107 are squeezed by the arc-shaped guide plate 124 and move forward under the limiting action of the carriage cross bar 106. When the inclined surface seats 107 move forward, they will push the interception net plate 201 to flip upward until the interception net plate 201 is completely parallel when the gate body 104 rises to the top. At the same time, the gate body 104 will push up the vertical slide bar 116 to pull out the positioning plug 117 from the inside of the positioning socket 115. Then, pull the U-shaped carriage 114 to push the cylinder 118 and the concave pressing frame 120 forward. After the forward movement is completed, start the cylinder 118 to push the concave pressing frame 120 to descend again. When the concave pressing frame 120 contacts the storage bin 202, it is blocked and stops. Then, the inner push plate 121 continues to descend until the pressing cylinder 123 passes through the circular socket 204 to press the double-arc blocking plate 208, and the double-arc blocking plate 208 is pressed into the inside of the retraction groove 207. At this time, the pull-out blocking frame 205 loses its limit. Then, push the pull-out blocking frame 205 out of the inside of the storage bin 202 and drive the sundries inside to be discharged together. Then, clean and maintain the gate body 104 and the interception net plate 201;

[0045] After the maintenance is completed, the drawer block 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 resistance plate 208 can be pressed against the inner side of the retraction groove 207 without being interfered with. After the drawer block 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. Then the double arc resistance plate 208 is pushed out under the elastic force of the second spring 209. The double arc resistance plate 208 is engaged with the storage box 202 to fix the drawer block 205. After the cylinder 118 has risen, the U-shaped slide 114 is pulled to drive the cylinder 118 to move back and reset. Then the motor 110 is started to drive the threaded rod 11 1 rotation allows the gate body 104 to descend, and after the gate body 104 descends, it no longer pushes on the vertical slide bar 116, allowing the positioning rod 117 to descend and insert into the inner side of the positioning socket 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 retaining seat 107 is no longer squeezed by the arc guide plate 124, and the intercepting screen 201 uses its own weight to flip toward each other and push the inclined surface retaining seat 107 to move backward and reset until the inclined surface retaining seat 107 is completely moved backward. At this time, the intercepting screen 201 is also in a vertical state. As the gate body 104 drives the inclined surface retaining seat 107 to descend, the limiting guide groove 108 also re-docking with the convex guide rod 210 to fix the intercepting screen 201.

8. The flood control method of a river basin flood control device according to claim 7, 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) using the threaded ring (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, so that the internal debris is intercepted by the intercepting mesh plate (201) when the water flows, and then the cylinder (118) is started to push the concave pressure frame (120) down. At the same time, due to the elastic force of the first spring (122) against the concave pressure frame (120), the concave pressure frame (120) and the internal pushing plate (121) are lowered. When the concave pressure 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 pressure frame (120) descends to the bottom, the debris will squeeze the buoyancy baffle (203) and push the buoyancy baffle (203) toward the inside of the storage box (202). The cylinder (118) is turned over until the concave pressing frame (120) contacts the storage box (202) and stops descending due to obstruction, but the cylinder (118) will continue to descend and push 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 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) to rise, and the buoyancy baffle (203) will float up under the buoyancy of the water and turn over close to the inner push plate (121), ensuring that the debris inside the storage box (202) will not float out of the 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 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 motor (110) is started to continuously pull up the gate body (104) by rotating the threaded rod (111), and the gate body (104) will use the slide cross bar (106) to synchronously drive the two inclined planes (107) to rise, and the inclined planes (107) rise to make the limiting guide groove (108) and the convex guide rod (210) Separated, at this time the intercepting mesh plate (201) loses its limit, 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 in the limiting action of the slide cross bar (106), and the forward movement of the inclined surface retaining seat (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 flat. The gate body (104) is in the state of row, and at the same time, the vertical slide bar (116) is pushed up to push the positioning rod (117) out from the inner side of the positioning socket (115), and then the U-shaped slide (114) is pulled 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. After the concave pressing frame (120) contacts the storage box (202), it is blocked and stops, 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 this time, the pull-out retaining frame (205) loses its limit, and then the pull-out retaining 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 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 retaining frame (205). After the cylinder (118) is raised, the U-shaped slide (114) is pulled to drive the cylinder (118) to move back 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 socket (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 intercepting 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 intercepting 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) also re-docking with the convex guide rod (210) to fix the intercepting mesh plate (201).
