Description

Technical Field

[0001] The invention relates to a barrier structure, in particular to a barrier structure for drainage ditches used in water conservancy projects, and belongs to the technical field of water conservancy projects. Background Art

[0002] In water conservancy projects, drainage ditches are used to drain rainwater and other liquids that need to be drained. They are usually continuous channels built into foundation buildings to prevent floods and water soaking upstream. During the use of drainage ditches, the water flow will be mixed with floating objects, such as some branches and leaves and man-made garbage. These debris will cause poor drainage after local accumulation in the drainage ditch, affecting the overall drainage function of the drainage ditch. Therefore, it is very necessary to set structural components in the drainage ditch to intercept debris.

[0003] For example, a Chinese invention patent document, with the publication number CN114481965B, discloses a drainage ditch barrier structure for water conservancy design, which relates to the technical field of water conservancy engineering. The barrier structure includes a fixed frame; it also includes an interception assembly and at least one rotating downward pressing member. The interception rod is deformed by the impact of the debris to buffer the impact caused by the debris, and the deformation of the interception rod drives the rotating downward pressing member to rotate downward, thereby moving larger debris downward so that the impact caused by it is directed toward the bottom of the water, and the buoyancy of the water is used to offset part of the impact. The interception assembly and the barrier mesh can be set to intercept the debris according to its size to avoid blockage caused by excessive concentration of debris.

[0004] Moreover, the barrier structure in the above document can also use the debris side pushing components to push the debris to the two sides of the interception mesh plate. However, although the above barrier structure can effectively block the debris, the debris is still located in the drainage ditch, and after excessive accumulation, it will still cause obstruction of water flow.

[0005] For example, the announcement number CN219586853U discloses a barrier structure for a drainage ditch, which can clean the surface of an interception plate and collect the cleaned garbage to ensure the drainage effect of the drainage ditch, and at the same time, has a buffering and vibration effect on the interception plate.

[0006] However, the cleaning structure in the barrier structure in the above document is similar in function to the debris side pushing component in the announcement number CN114481965B, which only relies on scraping and moving on the surface of the filter component to push away the debris. However, the debris cannot be cleared from the drain ditch, so the cleaning effect is limited and a good water flow cannot be guaranteed.

[0007] In view of this, the present invention is proposed. Summary of the invention

By providing a smaller barrier between large floating objects, a center rod 4 is fixed on the water pressure plate 2. The center rod 4 is used to increase the firmness of the barrier structure and can also be used as a component that penetrates into the bottom of the drainage ditch. When it is necessary to remove a small amount of bottom mud, a way to directly obtain mud can be provided for the outside world. A front frame 5 is fixed on the center rod 4. The front frame 5 is mainly used to fix the buffer bend plate 6, and the position of the buffer bend plate 6 is moved forward to keep the buffer bend plate 6 away from the barrier water-permeable plate 3 and the lifting and transporting device 8. When floating objects are present, the buffer bend plate 6 can be the first to contact the impact, and the front frame 5 can be used to fix the buffer bend plate 6. A buffer turning plate 6 is rotatably installed on the rack 5, and a power assembly 7 is installed between the side plates 1.

A lifting and transporting device 8 is installed between the side plates 1. The lifting and transporting device 8 is used to remove the floating objects under the obstruction to prevent the floating objects from accumulating on the barrier water-permeable plate 3, thereby affecting the water flow of the drainage ditch. The lifting and transporting device 8 is located above the barrier water-permeable plate, and the barrier water-permeable plate 3 is inclined. The end extends obliquely downward toward the drainage ditch, and a vertical hole 301 is opened on the barrier water-permeable plate 3. A gap is left between the bottom of the barrier water-permeable plate 3 and the water-pressing plate 2, but the gap needs to be adjusted according to the actual floating range of the floating objects, so that it is convenient to collect the floating objects. When in use, the floating objects are blocked and gathered on the top of the barrier water-permeable plate 3, and then the lifting and transportation device 8 can lift the intercepted floating objects and transport them out of the drainage ditch. The buffer inflection plate 6 cooperates with the inclined barrier water-permeable plate 3 to avoid direct impact of floating objects, thereby extending the service life of the components.

[0032] The power assembly 7 includes an arc shell plate 701 fixed between the side plates 1, and a rotating shaft 702 rotatably installed between the side plates 1 is provided below the arc shell plate 701. Rotating blades 703 are evenly fixed on the outer wall of the rotating shaft 702, so that it is convenient to use water flow to drive the rotating shaft 702 to rotate. The power assembly 7 can provide a power source for the lifting and transportation device 8 and the discharge mechanism 9. When there is water flow in the drainage ditch, the water flow pushes the rotating blades 703, which can drive the rotating shaft 702 to rotate.

[0033] The lifting and transporting device 8 includes a support plate 801, between which a limiting rod 802 is rotatably installed, and a conveyor belt 803 is sleeved on the limiting rod 802, and a hook plate 804 is fixed on the conveyor belt 803, and a leakage hole is opened on the hook plate 804. The first end of the conveyor belt 803 extends below the liquid surface of the drainage ditch, and the second end extends obliquely upward to the top of the power component 7, and a discharge mechanism 9 is provided below the second end. In this technical solution, the conveyor belt 803 is a chain plate belt, and a corresponding driving gear needs to be provided on the limiting rod 802. In order to better regulate the transportation trajectory of the discharged debris, three limiting rods 802 are used to limit the transportation trajectory of the conveyor belt 803, that is, a hook plate 804 is provided at each end of the conveyor belt 803. One, and set an additional limit rod 802 for transmitting power, so that it is convenient to regulate the range of movement of the conveyor belt 803, one end of the limit rod 802 extends to the outside of the support plate 801, and is fixed with a driven gear 805, and a reversing gear 806 is rotatably installed on the outer wall of the support plate 801 below the driven gear 805, and the reversing gear 806 is meshed with the driven gear 805. A force rod is installed on the reversing gear 806, and the force rod is connected to the rotating shaft 702 through the first transmission belt 807. In this way, it is convenient to drive the conveyor belt 803, and a vertical plate 302 extending upward is fixed on the top of the barrier water-permeable plate 3, and the vertical plate 302 is located on one side of the support plate 801, And it is fixed to the supporting plate 801, and an opening and closing plate 303 is rotatably installed between the vertical plates 302 near the top of the barrier water-permeable plate 3, and one end of the opening and closing plate 303 is close to the bottom of the conveyor belt 803, so that floating objects can be prevented from floating out from above the barrier water-permeable plate 3. When in use, the rotating shaft 702 rotates the force-bearing rod through the first transmission belt 807, and then the driven gear 805 meshing with the conversion gear rotates, so that the limiting rod 802 can rotate, and the conveyor belt 803 is operated. When discharging floating objects, the hook plate 804 rotates upward from the bottom of the liquid surface, so that the floating objects are brought out, and the water can be discharged through the leakage hole, and the hook plate 804 needs to have a certain amount of operating space when moving. However, floating objects will float into the gap between the hook plates 804, and the opening and closing plate 303 is fixed between the vertical plates 302. When no hook plate 804 is located at the vertical plates 302, the opening and closing plate 303 is closed between the vertical plates 302. When necessary, a limit block can be fixed on the side wall of the opening and closing plate 303 to prevent the opening and closing plate 303 from rotating excessively. When the hook plate 804 needs to pass between the vertical plates 302, it can push the opening and closing plate 303 to rotate, so that the hook plate 804 can move smoothly. The edge of the hook plate 804 is fixed with a raised edge, which can prevent the lifted floating objects from sliding off. Then these lifted floating objects can fall onto the discharge mechanism 9, and the discharge mechanism 9 can move these floating objects out of the drainage ditch.

[0034] The discharge mechanism 9 includes an arc groove 901, which is fixed above the side plate 1 and one end of which extends to the outside of the side plate 1. A discharge screw 902 is rotatably installed in the side plate 1, and a spiral plate 903 is provided on the discharge screw 902. One end of the discharge screw 902 passes through the arc groove 901 and is dynamically connected to the rotating shaft 702 through a second transmission belt 904, so that floating objects can be continuously discharged. The second transmission belt 904 can drive the discharge screw 902 to rotate, and then drive the spiral plate 903 to continuously rotate in the arc groove 901, and the floating objects falling into the arc groove 901 can be moved to the outside of the drainage ditch under the continuous push of the spiral plate 903.

[0035] The front frame 5 includes a platform plate 501 fixed to the center rod 4. The platform plate 501 can serve as a walking platform for passing through the drainage ditch. At the same time, when it is necessary to extract the sediment at the bottom of the drainage ditch, the water pump can be placed on the platform plate 501. A front probe rod 502 is fixed to the bottom of the platform plate 501. One end of the front probe rod 502 is provided with a mounting hole for rotating and fixing a buffer inflection plate 6. One end of the buffer inflection plate 6 extends obliquely upward to form a short plate 601. The buffer inflection plate The bottom end of 6 extends obliquely downward to form a long plate 602, and an outflow strip hole is opened on the long plate 602. A counterweight block 603 is fixed on the bottom side wall of the long plate 602, which can better buffer the impact. A water retaining plate 503 is slidably installed on the front probe rod 502. The bottom end of the water retaining plate 503 extends downward, and the bottom of the water retaining plate 503 is an arc-shaped arc bent toward the buffer inflection plate 6. A traction rope 503 is fixed on the top side wall of the water retaining plate 503. 4. A limiting pulley 505 is fixed on the upper surface of the front probe rod 502, and the traction rope 504 passes through the bottom of the limiting pulley 505 and is fixed to the side wall of the short plate 601, so that the water flow can be used to reset the buffer turn plate 6. In order to make the water retaining plate 503 slide more stably, two water retaining plate members 503 can be set and connected and fixed to each other through a connecting rod. When in use, the buffer turn plate 6 itself is due to the counterweight block 603, and the long plate member 602 hangs in the gutter. When impacted, the buffer turn plate 6 can rely on its own shape to unload the force, and then under the continuous impact of the water flow, the long plate member 602 continues to rotate driven by the floating objects, and then resets under the influence of the counterweight block 603, and the water flow can push the water retaining plate member 503 to slide away from the buffer turn plate 6, and when the buffer turn plate 6 rotates, it can pull the water retaining plate member 503 to slide, thereby forming resistance to the rotation of the buffer turn plate 6, and further playing a buffering role.

[0036] A sewage extraction channel is provided in the center rod 4, and the bottom end of the center rod 4 is located at one side edge of the water pressure plate 2, and an upwardly extending sand retaining plate 201 is provided at the edge of the water pressure plate 2, and an entrance portion 202 connected to the sewage extraction channel is opened on the sand retaining plate 201. The upper surface of the water pressure plate 2 is an inclined surface, which is inclined from one side of the sand retaining plate 201 to the opposite side. A support frame is fixed on the side wall of the center rod 4, and the bottom end of the support frame is in contact with the bottom of the drainage ditch. The support frame is used to provide additional supporting force for the center rod 4, which can facilitate the extraction of sediment at the bottom of the drainage ditch. When in use, water flows over the top of the water pressure plate 2. The faster the water flow rate, the more it can press the water pressure plate 2, thereby stabilizing the structure. The sediment can accumulate at the sand retaining piece. When it needs to be discharged, the external suction equipment can be connected to the top of the center rod 4, and the sediment at the bottom of the drainage ditch can be sucked out.

[0037] The present barrier structure can effectively mitigate the impact of floating objects and avoid damage to components due to impact force. After intercepting the floating objects, the lifting and transporting device 8 can transport and discharge the intercepted floating objects, thereby continuously ensuring smooth drainage of the drainage ditch. Moreover, the operation of the components mainly relies on the flow drive of water flow, which can reduce the dependence on external power resources. After the present barrier structure is placed in the drainage ditch, the water pressure components can provide better stability for the entire structure, avoid displacement of the structure under the impact of water flow, and facilitate personnel to extract mud and sand at the bottom of the drainage ditch.

[0038] When in use, floating objects are blocked and collected on the top of the barrier water-permeable plate 3, and then the lifting and transporting device 8 can lift the intercepted floating objects and transport them out of the drainage ditch. The buffer turning plate 6 cooperates with the inclined barrier water-permeable plate 3 to avoid direct impact of floating objects, thereby extending the service life of the components. The power component 7 can provide a power source for the lifting and transporting device 8 and the discharge mechanism 9. When there is water flow in the drainage ditch, the water flow pushes the rotating blade 703, which can drive the rotating shaft 702 to rotate. The rotating shaft 702 rotates the force-bearing rod through the first transmission belt 807, thereby meshing with the conversion gear. The driven gear 805 rotates, so that the limit rod 802 can rotate, and the conveyor belt 803 operates. When discharging floating objects, the hook plate 804 rotates upward from the bottom of the liquid surface, so as to bring out the floating objects, and the water can be discharged through the leak hole. When the hook plate 804 moves, a certain operating space is required, but the floating objects will float into the gap between the hook plates 804, and the opening and closing plate 303 is fixed between the vertical plates 302. When there is no hook plate 804 located at the vertical plates 302, the opening and closing plate 303 is closed between the vertical plates 302, and the limit block can be fixed on the side wall of the opening and closing plate 303 when necessary. , thereby preventing the opening and closing plate 303 from rotating excessively. When the hook plate 804 needs to pass between the vertical plates 302, it can push the opening and closing plate 303 to rotate, thereby allowing the hook plate 804 to move smoothly. The edge of the hook plate 804 is fixed with a raised edge, which can prevent the lifted floating objects from sliding off. Then these lifted floating objects can fall onto the discharge mechanism 9, and the discharge mechanism 9 can move these floating objects out of the drainage ditch. The second transmission belt 904 can drive the discharge screw 902 to rotate, thereby driving the spiral plate 903 to rotate continuously in the arc groove 901, and the floating objects that fall into the arc groove 901 can The spiral plate 903 is continuously pushed and moves to the outside of the drain ditch. The buffer bend plate 6 itself has a long plate part 602 hanging in the drain ditch due to the counterweight block 603. When impacted, the buffer bend plate 6 can rely on its own shape to unload the force. Then, under the continuous impact of the water flow, the long plate part 602 continues to rotate driven by the floating objects, and then resets under the influence of the counterweight block 603. The water flow can push the water retaining plate part 503 to slide away from the buffer bend plate 6. When the buffer bend plate 6 rotates, it can pull the water retaining plate part 503 to slide, thereby forming resistance to the rotation of the buffer bend plate 6, and further playing a buffering role.
