Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to a river garbage interception device for water conservancy projects. Background Technology

[0002] Water conservancy projects are the core means of river management. By constructing flood control dikes, reservoirs, flood diversion areas, and other facilities to regulate water flow, they directly address core issues such as floods and water shortages. For example, the Three Gorges Project reduces the peak flow of the Yangtze River in its middle and lower reaches by impounding floodwaters, while also providing power generation and navigation functions. River management provides a scientific planning basis for water conservancy project construction, requiring a systematic analysis of the basin's hydrological characteristics, ecologically sensitive areas, and socio-economic needs to ensure that the project layout aligns with the river's evolution.

[0003] Existing patent CN212358228U discloses a river garbage interception device, including a collection trough, a net, a hanging ring, a hook seat, a base plate, a side plate, a slot, a foam pad, a connecting female seat, a through hole, a threaded hole, a baffle, a connecting buckle, a foam block, a connecting bolt, a fixing plate, insertion holes, and a movable insert plate. The advantages of this prior art are: the net is detachably connected to the collection trough by the hanging ring on the hook seat, which makes it easy to remove the net full of river garbage and clean it, thus allowing the device to be used for a long time. The collection trough is trapezoidal, and the baffles connected to both sides of the collection trough are spread out in a diffused manner, which can have the effect of collecting river garbage, so as to collect the garbage into the net. There are three insertion holes on the fixing plate, which are arranged from top to bottom on the plate. The fixing plate is fixed to the riverbanks on both sides of the river by fixing piles passing through the insertion holes to prevent the device from moving with the flow of river water.

[0004] However, when the garbage floating in the river is large, if the mesh openings of the grating are too large, the garbage can easily pass through the grating and cannot be effectively intercepted, resulting in poor interception effect. When the garbage is small, if the mesh openings are too small, although the garbage can be intercepted, it will cause the mesh openings to become clogged, affecting the normal flow of water, increasing the resistance and energy consumption of the equipment, and also causing great inconvenience to the subsequent cleaning work. Utility Model Content

[0005] The purpose of this utility model is to provide a river garbage interception device for water conservancy projects, aiming to solve the technical problems in the prior art where, when the size of the floating garbage in the river is large, if the aperture of the grating plate is too large, the garbage can easily pass directly through the grating plate and cannot be effectively intercepted, resulting in poor interception effect; while when the size of the garbage is small, if the aperture of the grating plate is too small, although the garbage can be intercepted, it will cause blockage of the grating plate aperture, affecting the normal flow of water, increasing the resistance and energy consumption of the equipment operation, and also causing great inconvenience to the subsequent cleaning work.

[0006] To achieve the above objectives, this utility model employs a river debris interception device for water conservancy projects, comprising multiple interception plates and a mounting frame. One side of each interception plate is the head end, and the other side is the tail end. A driven gear is disposed above each interception plate. A protective box is disposed above the mounting frame, and a driving rack plate is slidably disposed within the protective box. A first screw is disposed at one end of the driving rack plate.

The driven gear extends into the protective box. The driving rack plate meshes with the corresponding driven gear and is located on one side of the multiple driven gears. The first threaded sleeve is threadedly connected to the first screw and is sleeved on the first screw. The worm meshes with the worm gear and is located above the worm gear.

[0007] The multiple interceptor plates are arranged in an inclined manner in the flow channel, and the gap between the multiple interceptor plates can be controlled by the distance between the beginning and end of two adjacent interceptor plates.

[0008] The river debris interception equipment for water conservancy projects further includes a cleaning component, which includes a second threaded sleeve, a cleaning brush, a second screw, and an interception cover. The second threaded sleeve is fixedly connected to the cleaning brush and is located above the cleaning brush, with the cleaning brush located on the end face of the corresponding interception plate. The second threaded sleeve is also threadedly connected to the second screw and is sleeved on the second screw. The second screw is rotatably mounted on one side of the mounting frame via two support blocks and is driven by a second motor.

[0011] This utility model discloses a river debris interception device for water conservancy projects, comprising multiple interception plates and a mounting frame. One side of each interception plate is the head end, and the other side is the tail end. A driven gear is disposed above each interception plate.

Detailed Implementation

[0022] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0023] Please see Figures 1 to 8This utility model provides a river garbage interception device for water conservancy projects, including multiple interception plates 1 and mounting frames 2. One side of each interception plate 1 is a head end 3, and the other side is a tail end 4. A driven gear 5 is arranged above the interception plate 1. A protective box 6 is arranged above the mounting frame 2. An active rack plate 7 is slidably arranged inside the protective box 6. A first screw 8 is arranged at one end of the active rack plate 7. A flow groove 9 is provided in the middle of the mounting frame 2. A mounting box 10 is arranged at one end of the mounting frame 2. A lifting frame 11 is arranged at the bottom of the mounting box 10. A rotatable support is mounted on the lifting frame 11 via a bearing. A first threaded sleeve 12 is provided, and a worm gear 13 is provided on the outer side of the first threaded sleeve 12. A worm 15 is provided on the inner top of the mounting box 10 through the transmission of a first motor 14. A plurality of intercepting plates 1 are rotatably connected to the mounting bracket 2 and are located in the flow groove 9. The driven gear 5 extends into the protective box 6. The driving rack plate 7 meshes with the corresponding driven gear 5 and is located on one side of the plurality of driven gears 5. The first threaded sleeve 12 is threadedly connected to the first screw 8 and is sleeved on the first screw 8. The worm 15 meshes with the worm gear 13 and is located above the worm gear 13.

[0024] In this embodiment, the flow channel 9 in the middle of the mounting frame 2 provides a passage for river water flow, ensuring that water can pass through normally. Multiple intercepting plates 1 are rotatably connected to the mounting frame 2 and located in the flow channel 9. The driven gear 5 above them meshes with the active rack plate 7 slidably disposed in the protective box 6. This design allows the active rack plate 7 to drive the multiple intercepting plates 1 to rotate when it moves, thereby adjusting the angle of the intercepting plates 1 to adapt to rivers with different flow rates and directions. The first screw 8 is threadedly connected to the first threaded sleeve 12, and the worm gear 13 is disposed on the outside of the first threaded sleeve 12. The worm 15 is driven by the first motor 14 to mesh with the worm gear 13 at the top of the mounting box 10. This transmission structure allows the first motor 14 to precisely control the rotation of the first threaded sleeve 12, thereby driving the first screw 8 to move and providing power for the sliding of the active rack plate 7. This achieves precise control of the angle of the intercepting plates 1, improves the adaptability of the equipment to different working conditions, and helps to intercept river garbage more effectively.

[0025] Furthermore, multiple interceptor plates 1 are arranged in an inclined manner in sequence within the flow channel 9, and the gap between the multiple interceptor plates 1 can be controlled by the distance between the beginning and end of two adjacent interceptor plates 1.

[0026] In this embodiment, when the size of the floating garbage in the river is large, the distance between the first and last ends of the adjacent interceptor plates 1 can be appropriately increased, thereby increasing the interception gap and preventing the garbage from passing directly through the interceptor plates 1 and failing to be effectively intercepted. When the size of the garbage is small, the distance between the first and last ends of the adjacent interceptor plates 1 can be reduced, narrowing the interception gap and preventing the garbage from leaking through the gap. At the same time, the gap will not be too small and will not cause blockage of the pores, ensuring the normal passage of water flow, effectively improving the garbage interception effect, and enhancing the equipment's ability to intercept garbage of different sizes.

[0027] Furthermore, the river debris interception equipment for water conservancy projects also includes a cleaning component, which includes a second threaded sleeve 16, a cleaning brush 17, a second screw 18, and an interception cover 19. The second threaded sleeve 16 is fixedly connected to the cleaning brush 17 and is located above the cleaning brush 17, and the cleaning brush 17 is located on the end face of the corresponding interception plate 1. The second threaded sleeve 16 is also threadedly connected to the second screw 18 and is sleeved on the second screw 18. The second screw 18 is rotatably mounted on one side of the mounting frame 2 through two support blocks, and the second screw 18 is driven by a second motor 20. The interception cover 19 is fixedly connected to the mounting frame 2 and is located at the other end of the mounting frame 2.

[0028] In this embodiment, this structure enables the second motor 20 to drive the second screw 18 to rotate, thereby driving the second threaded sleeve 16 and the cleaning brush 17 to move axially along the second screw 18. The cleaning brush 17 is located on the end face of the corresponding interceptor plate 1, and can promptly clean the garbage attached to the surface of the interceptor plate 1 after the interceptor plate 1 intercepts the garbage, so that the cleaned garbage is pushed into the interceptor cover 19 to prevent the garbage from accumulating and affecting the interception effect and water flow.

[0029] Furthermore, the cleaning assembly also includes a positioning rod 21 and a collection cover 22. The inner bottom of both the collection cover 22 and the interception cover 19 has a water outlet 24. The positioning rod 21 is fixedly connected to the corresponding support block and is located between the two support blocks, and also passes through the top of the cleaning brush 17. The collection cover 22 is slidably connected to the interception cover 19 and is located inside the interception cover 19.

[0030] In this embodiment, the positioning rod 21 can help prevent the cleaning brush 17 from rotating unexpectedly, and the collection cover 22 can help collect the garbage in the interception cover 19 and clean it up in a unified manner later.

[0031] Furthermore, a support wheel 23 is provided below the cleaning brush 17, and a wheel groove 25 is provided on one side of the mounting bracket 2, with the support wheel 23 located within the wheel groove 25.

[0032] In this embodiment, the cooperation between the support wheel 23 and the wheel groove 25 provides additional support for the cleaning brush 17, reduces the friction of the cleaning brush 17 during movement, enables the cleaning brush 17 to move more smoothly, and reduces energy consumption during the cleaning process.

[0033] In using this utility model, the first motor 14 drives the worm gear 15, which meshes with the worm wheel 13 on the outside of the first threaded sleeve 12, causing the first threaded sleeve 12 to rotate. The first threaded sleeve 12 is threadedly connected to the first screw 8, causing the first screw 8 to move, thereby pushing the active rack plate 7 to slide within the protective box 6. The active rack plate 7 meshes with the driven gear 5, thereby driving multiple interceptor plates 1 to rotate, changing the distance between the head and tail ends of adjacent interceptor plates 1, and realizing the gap adjustment of the interceptor plates 1. In terms of cleaning up garbage, the second motor 20 drives the second screw 18, which is threadedly connected to the second threaded sleeve 16. The second threaded sleeve 16 is fixed to the cleaning brush 17, driving the cleaning brush 17 to move axially along the second screw 18. The cleaning brush 17 is located at the end face of the interception plate 1, sweeping the intercepted garbage to the collection cover 22 to collect the garbage, thus realizing garbage sweeping and collection. This method solves the technical problem that when the size of the floating garbage in the river is large, if the aperture of the grating plate is too large, the garbage can easily pass directly through the grating plate and cannot be effectively intercepted, resulting in poor interception effect; while when the size of the garbage is small, if the aperture of the grating plate is too small, although it can intercept the garbage, it will cause the grating plate aperture to be blocked, affecting the normal flow of water, increasing the resistance and energy consumption of the equipment, and also bringing great inconvenience to the subsequent cleaning work.

[0034] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
