Description

Technical Field

[0001] This application relates to the field of municipal engineering, and in particular to an anti-clogging trench cover. Background Technology

[0002] A trench refers to an outdoor trench inside an industrial or civil building, or within an industrial or civil building complex. Currently, in municipal ground facilities, trenches are installed in squares, roads, and other areas to quickly drain accumulated water. These trenches are all covered with trench covers.

[0003] Due to the complexity of the outdoor environment, garbage, leaves, or mud often clog the drainage channels on the trench covers, affecting the normal drainage function of the trench covers. The conventional cleaning method is to manually unblock the blockage, which is labor-intensive and inefficient. The related technology of dredging garbage by cutting grooves has certain limitations. Summary of the Invention

[0004] To prevent debris from clogging the trench cover, this application provides an anti-clogging trench cover.

[0005] The anti-clogging trench cover provided in this application adopts the following technical solution: A clog-resistant trench cover includes a plate body with several channels for water and garbage to pass through. A cleaning roller is provided on the plate body and is rotatably connected to the inner wall of the channel. A barrier net for blocking garbage is provided on the plate body. A water-absorbing block is provided inside the plate body. A support column on the barrier net passes through the plate body and abuts against the water-absorbing block. A first drive assembly for driving the cleaning roller to rotate is provided on the plate body.

[0006] By adopting the above technical solution, when water flows through the slab, it is discharged into the ditch through the channel. In dry weather, the water-absorbing block does not absorb water and expands. At this time, the debris will be blocked outside the channel by the barrier net, preventing it from entering the channel and the ditch, thus preventing the accumulation of debris in the dry ditch and affecting the flow of water in the ditch during rainy weather. In rainy weather, the water-absorbing block absorbs rainwater, causing the barrier net to move away from the channel. At this time, the water flow can smoothly enter the channel. When a large amount of debris blocks the channel and affects normal drainage, the first drive component drives the cleaning roller to rotate. The rotating cleaning roller pushes the debris accumulated in the channel into the ditch. By setting up the barrier net and the cleaning roller, the barrier net can prevent the accumulation of debris in the dry ditch and prevent it from affecting the normal flow of water in the ditch during rainy weather. The cleaning roller will clean the debris accumulated in the channel during rainy weather and move it outside the channel, preventing it from affecting the normal drainage of the slab.

[0007] Preferably, the first drive assembly includes a first drive shaft and a first crown gear. The first drive shaft passes through the plate body and is rotatably connected to the plate body. The first crown gear is fixedly sleeved on the end of the cleaning roller near the first drive shaft. A first spur gear is fixedly sleeved on the first drive shaft. The first crown gear meshes with the first spur gear. The plate body is provided with a second drive assembly for driving the first drive shaft to rotate.

[0008] By adopting the above technical solution, the second drive component drives the first drive shaft to rotate, the rotation of the first drive shaft causes the first spur gear to rotate, the rotation of the first spur gear causes the first crown gear to rotate, the rotation of the first crown gear causes the cleaning roller to rotate, and the rotation of the cleaning roller pushes the debris in the through groove and pushes it out of the through groove.

[0009] Preferably, the second drive assembly includes a toothed belt and a push block. A second spur gear is fixedly sleeved on the end of the first drive shaft away from the first spur gear. A support roller is rotatably mounted inside the plate. The toothed belt is wound around the second spur gear and the support roller. The push block is fixedly connected to the side wall of the toothed belt away from the second spur gear. A third drive assembly for driving the toothed belt is provided on the plate.

[0010] By adopting the above technical solution, the third drive component drives the toothed belt to run, the toothed belt runs, the second spur gear rotates, the second spur gear rotates, the first drive shaft rotates, the first drive shaft rotates, the first spur gear rotates, the first spur gear rotates, the first crown gear rotates, the first crown gear rotates, the cleaning roller rotates, and the cleaning roller rotates to push the debris in the through groove and push it out of the through groove.

[0011] Preferably, the third driving component includes a coil spring, a second driving shaft passes through the plate body, the coil spring is wound around the second driving shaft, a traction rope is fixedly connected to the coil spring, the end of the traction rope away from the coil spring is fixedly connected to the push block, a fourth driving component for driving the push block to move is provided on the plate body, a control component for limiting the rotation of the second driving shaft is provided on the plate body, and a fixing component for limiting the movement of the push block is provided on the plate body.

[0012] By adopting the above technical solution, the fourth drive component drives the push block to move, the push block moves and compresses the coil spring, the push block moves and causes the toothed belt to run, at which time the toothed belt drives the cleaning roller to rotate. After reaching the position farthest from the coil spring, the fixing component restricts the movement of the push block, and at the same time the control component restricts the rotation of the second drive shaft. At this time, the push block cannot return to the initial position under the action of the coil spring. Since the push block moves to the farthest point from the coil spring, when the fixing component releases the push block and the control component stops restricting the rotation of the second drive shaft, the push block has a large force under the action of the coil spring, which can indirectly drive the cleaning roller to effectively clean the garbage in the channel.

[0013] Preferably, the fourth drive assembly includes a slide and a reciprocating screw. The reciprocating screw is rotatably mounted in the plate body and rotatably connected to the plate body. The slide is sleeved on the reciprocating screw and threadedly engaged with it. The slide abuts against the push block. An impeller is rotatably mounted on the side wall of the plate body near the trench. A third spur gear is fixedly sleeved on the reciprocating screw, and a second crown gear is fixedly sleeved on the impeller. The second crown gear meshes with the third spur gear.

[0014] By adopting the above technical solution, in rainy weather, the water flow in the ditch drives the impeller to rotate. The rotation of the impeller causes the second crown gear to rotate, the rotation of the second crown gear causes the third spur gear to rotate, the rotation of the third spur gear causes the reciprocating screw to rotate, the rotation of the reciprocating screw causes the slide to move, the movement of the slide causes the push block to move, and after the slide pushes the push block to the limit of the fixed component, the slide moves away from the push block under the action of the reciprocating screw.

[0015] Preferably, the control component includes a control wheel and a control rod. The control wheel is fixedly sleeved on the second drive shaft. A third drive shaft passes through the plate body and is rotatably connected to the plate body. The control rod is sleeved on the third drive shaft. The control wheel and the control rod are engaged. A torsion spring is provided on the third drive shaft. A push plate is fixedly connected to the third drive shaft and can abut against the slide.

[0016] By adopting the above technical solution, during rainy weather, the water flow in the ditch drives the impeller to rotate. The impeller rotation causes the second crown gear to rotate, which in turn causes the third spur gear to rotate. The third spur gear rotation causes the reciprocating screw to rotate, which in turn causes the slide to move. The slide's movement causes the push block to move as well. After the slide pushes the push block to the fixed component's limit, the slide moves away from the push block under the action of the reciprocating screw, and the slide comes into contact with the push plate. The slide pushes the push plate to rotate around the third drive shaft. The push plate's movement causes the third drive shaft to rotate, which in turn causes the control lever to rotate. The control lever's rotation releases the restriction on the control wheel, allowing the second drive shaft to rotate normally. At this time, if there is any [something] in the channel... When debris is removed, the fixing component releases the restriction on the push block. Under the action of the coil spring, the coil spring pulls the push block to move. The movement of the push block causes the toothed belt to run, which in turn causes the second spur gear to rotate. The rotation of the second spur gear causes the first drive shaft to rotate, which in turn causes the first spur gear to rotate. The rotation of the first spur gear causes the first crown gear to rotate, which in turn causes the cleaning roller to rotate. The rotation of the cleaning roller pushes the debris in the channel and pushes it out of the channel. The fixing component and the control component are used to restrict the movement of the push block, ensuring that the push block moves under the maximum traction force of the coil spring. This allows the cleaning roller to apply a larger force to the debris, improving the cleaning effect of the cleaning roller.

[0017] Preferably, the fixing assembly includes a rod and a trigger plate. The trigger plate passes through the inner wall of the through groove away from the cleaning roller. The rod is fixedly connected to the trigger plate. The end of the rod away from the trigger plate passes into the push block. The push block has a slot for engaging with the rod. The side wall of the rod near the push block has an inclined surface. A first return spring is fixedly connected to the trigger plate. The end of the first return spring away from the trigger plate slides against the inner wall of the through groove.

[0018] By adopting the above technical solution, during rainy weather, the water flow in the ditch drives the impeller to rotate. The rotation of the impeller causes the second crown gear to rotate, which in turn causes the third spur gear to rotate. The rotation of the third spur gear causes the reciprocating screw to rotate, which in turn causes the slide to move. The slide moves the push block, which in turn moves the push block. The push block is then pushed to the insertion rod position, and the insertion rod is inserted into the slot. At this point, the push block cannot move under the action of the coil spring. After debris accumulates in the channel, the debris pushes the trigger plate to move. The trigger plate moves and compresses the first return spring. The trigger plate moves, causing the insertion rod to move. The insertion rod moves away from the slot. After the control component releases the restriction of the second drive shaft, the coil spring pulls the push block to move and drives the cleaning roller to rotate.

[0019] Preferably, the cleaning roller is provided with a plurality of conical blocks.

[0020] By adopting the above technical solution, the conical block can increase the friction between the cleaning roller and the debris, thereby improving the cleaning effect of the cleaning roller.

[0021] Preferably, the side wall of the through groove away from the cleaning roller is provided with an inclined surface.

[0022] By adopting the above technical solution, under the action of the inclined surface of the channel, after the debris moves to the top of the plate, the debris can enter the channel along the inclined surface, reducing the possibility of the debris directly covering the channel.

[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up a barrier net and a cleaning roller, the barrier net can prevent debris from accumulating in the dry ditch and prevent it from affecting the normal flow of water in the ditch during rainy weather. The cleaning roller will clean the debris accumulated in the channel during rainy weather and remove it from the channel to prevent it from affecting the normal drainage of the board. 2. By setting up a fixing component and a control component, the fixing component and the control component are used to limit the movement of the push block, ensuring that the push block moves under the traction force of the coil spring when the force is at its maximum. This allows the cleaning roller to apply a larger force to the debris, thereby improving the cleaning effect of the cleaning roller. 3. Under the action of the inclined surface of the through groove, after the debris moves to the top of the plate, the debris can enter the through groove along the direction of the inclined surface, reducing the possibility of the debris directly covering the through groove.

[0029] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0030] This application discloses an anti-clogging trench cover. (See attached embodiment.) Figure 1 A clog-resistant trench cover includes a panel 1.

[0031] Reference Figure 1 as well as Figure 2 The plate 1 is horizontally arranged, and two through slots 11 are provided along its length. The two through slots 11 are symmetrically arranged along the axis of the cover plate. A barrier net 13 is provided on the top of the plate 1, covering the two through slots 11. One end of the barrier net 13 is inserted into the plate 1. A water-absorbing block 14 is provided inside the plate 1 along its length, and the barrier net 13 abuts against the water-absorbing block 14.

[0032] Reference Figure 1 as well as Figure 2 When water flows through plate 1, it is discharged into the ditch through channel 11. In dry weather, the water-absorbing block 14 does not absorb water and expands. At this time, the debris will be blocked outside the channel 11 by the barrier net 13 and cannot enter the channel 11 or the ditch, thus preventing the accumulation of debris in the dry ditch and affecting the flow of water in the ditch during rainy weather. In rainy weather, the water-absorbing block 14 absorbs rainwater, causing the barrier net 13 to move. The barrier net 13 moves away from the channel 11, and at this time the water flow can smoothly enter the channel 11.

[0033] Reference Figure 2A cleaning roller 12 is rotatably mounted inside the plate body 1.

Several conical blocks 121 are provided on the cleaning roller 12, evenly distributed along its length. An inclined surface is provided on the sidewall of the through groove 11 away from its corresponding cleaning roller 12. Under the action of the inclined surface, after debris moves to the top of the plate body 1, it can enter the through groove 11 along the inclined surface, reducing the possibility of debris directly covering the through groove 11. The conical blocks 121 increase the friction between the cleaning roller 12 and the debris, improving the cleaning effect of the cleaning roller 12.

[0034] Reference Figure 2 as well as Figure 3 A first drive assembly 2 is provided on the plate body 1. The first drive assembly 2 includes a first drive shaft 21 and a first crown gear 22.

A first spur gear 23 is fixedly sleeved on the end of the first drive shaft 21 near the cleaning roller 12. The first spur gear 23 and the first crown gear 22 mesh with each other. The first drive shaft 21 corresponds one-to-one with the cleaning roller 12.

[0035] Reference Figure 2 as well as Figure 3 The rotation of the first drive shaft 21 causes the first spur gear 23 to rotate, the rotation of the first spur gear 23 causes the first crown gear 22 to rotate, the rotation of the first crown gear 22 causes the cleaning roller 12 to rotate, and the rotation of the cleaning roller 12 pushes the debris in the through groove 11 and pushes it out of the through groove 11.

[0036] Reference Figure 2 as well as Figure 3 A second drive assembly is provided on the plate 1, which includes a toothed belt 24 and a push block 25.

The toothed belt 24 is horizontally arranged, and the push block 25 is fixedly connected to the top surface of the toothed belt 24.

[0037] Reference Figure 2 as well as Figure 3The movement of the push block 25 causes the toothed belt 24 to run, the running of the toothed belt 24 causes the second spur gear 26 to rotate, the rotation of the second spur gear 26 causes the first drive shaft 21 to rotate, the rotation of the first drive shaft 21 causes the first spur gear 23 to rotate, the rotation of the first spur gear 23 causes the first crown gear 22 to rotate, the rotation of the first crown gear 22 causes the cleaning roller 12 to rotate, and the rotation of the cleaning roller 12 pushes the debris in the through groove 11 and pushes it out of the through groove 11.

[0038] Reference Figure 2 as well as Figure 3 A third drive assembly 3, including a coil spring 31, is disposed within the plate body 1. A second drive shaft 32 is horizontally inserted through the end of the plate body 1 near the first drive shaft 21, and the second drive shaft 32 is rotatably connected to the plate body 1. The coil spring 31 is wound around the second drive shaft 32. A traction rope 33 is fixedly connected to the side wall of the push block 25 near the coil spring 31, and the end of the traction rope 33 away from the push block 25 is fixedly connected to the coil spring 31. The coil spring 31 serves as the driving force for the movement of the push block 25, enabling the push block 25 to have a certain explosive force when moving, which helps the cleaning roller 12 to clean the severely clogged through groove 11.

[0039] Reference Figure 2 as well as Figure 3 A control assembly 4 is provided inside the plate body 1. The control assembly 4 includes a control wheel 41 and a control rod 42.

A torsion spring is provided on the third drive shaft 43, and a push plate 44 is fixedly sleeved on the end of the third drive shaft 43 away from the control rod 42.

[0040] Reference Figure 2 as well as Figure 3 A fourth drive assembly is provided on the plate body 1, which includes a slide 34 and a reciprocating screw 35. The reciprocating screw 35 is horizontally inserted into the plate body 1 and is rotatably connected to the plate body 1. The slide 34 is sleeved on the reciprocating screw 35 and is threadedly engaged with the reciprocating screw 35. One side of the slide 34 can abut against the push block 25, and the other side of the slide 34 can abut against the push plate 44.

[0041] Reference Figure 2 as well as Figure 3An impeller 36 is vertically inserted through the bottom surface of the plate 1, and the impeller 36 is rotatably connected to the plate 1. The top of the impeller 36 is inserted into the plate 1, and a second crown gear 38 is fixedly sleeved on the end of the impeller 36 located inside the plate 1. A third spur gear 37 is fixedly sleeved on the end of the reciprocating screw 35 near the impeller 36, and the third spur gear 37 meshes with the second crown gear 38.

[0042] Reference Figure 2 as well as Figure 3 During rainy weather, the water flow in the ditch drives the impeller 36 to rotate. The rotation of the impeller 36 causes the second crown gear 38 to rotate, which in turn causes the third spur gear 37 to rotate. The rotation of the third spur gear 37 causes the reciprocating screw 35 to rotate, which in turn causes the slide 34 to move. The movement of the slide 34 causes the push block 25 to move, which in turn causes the toothed belt 24 to run. The running of the toothed belt 24 causes the second spur gear 26 to rotate, which in turn causes the first drive shaft 21 to rotate. The rotation of the first drive shaft 21 causes the first spur gear 23 to rotate, which in turn causes the first crown gear 22 to rotate. The rotation of the first crown gear 22 causes the cleaning roller 12 to rotate, which pushes the debris in the channel 11 and pushes it out of the channel 11.

[0043] Reference Figure 2 as well as Figure 4 A fixing assembly is provided on the plate body 1, including a rod 45 and a trigger plate 46. The trigger plate 46 is slidably inserted into the side wall of the through groove 11 away from the cleaning roller 12, and the trigger plate 46 is slidably engaged with the inner side wall of the through groove 11. A first return spring 47 is fixedly connected to the side wall of the trigger plate 46 away from the corresponding cleaning roller 12, and the end of the first return spring 47 away from the trigger plate 46 is fixedly connected to the inner side wall of the through groove 11. The rod 45 is slidably inserted into the plate body 1, one end of the rod 45 is fixedly connected to the trigger plate 46, and the other end of the rod 45 is inserted into the push block 25. The push block 25 has a slot for engaging with the rod 45, and the side wall of the rod 45 near the push block 25 has an inclined surface.

[0044] Reference Figure 2 , Figure 3 as well as Figure 4During rainy weather, the water flow in the ditch drives the impeller 36 to rotate. The rotation of the impeller 36 causes the second crown gear 38 to rotate, which in turn causes the third spur gear 37 to rotate. The rotation of the third spur gear 37 causes the reciprocating screw 35 to rotate, which in turn causes the slide 34 to move. The movement of the slide 34 causes the push block 25 to move. The slide 34 pushes the push block 25 to the position of the insertion rod 45, which is then inserted into the slot. At this time, the push block 25 cannot move under the action of the coil spring 31. After debris accumulates in the through groove 11, the debris pushes the trigger plate 46 to move. The movement of the trigger plate 46 compresses the first return spring 47, causing the insertion rod 45 to move. The insertion rod 45 moves away from the slot. After the control component 4 releases the restriction of the second drive shaft 32, the coil spring 31 pulls the push block 25 to move and drives the cleaning roller 12 to rotate.

[0045] The implementation principle of an anti-clogging trench cover according to an embodiment of this application is as follows: In rainy weather, the water flow in the trench drives the impeller 36 to rotate. The rotation of the impeller 36 causes the second crown gear 38 to rotate, which in turn causes the third spur gear 37 to rotate. The rotation of the third spur gear 37 causes the reciprocating screw 35 to rotate, which in turn causes the slide 34 to move. The movement of the slide 34 causes the push block 25 to move, which in turn compresses the coil spring 31. The movement of the push block 25 causes the toothed belt 24 to run. At this time, the toothed belt 24 drives the cleaning roller 12 to rotate. After reaching the position furthest from the coil spring 31, the slide 34 pushes the push block 25 to the position of the insertion rod 45. The insertion rod 45 is inserted into the slot. At this time, the push block 25 cannot move under the action of the coil spring 31. After debris accumulates in the through slot 11, the debris pushes the trigger plate 46 to move. The trigger plate 46 moves and compresses the first return spring 47. The movement of the trigger plate 46 causes the insertion rod 45 to move. The insertion rod 45 moves away from the slot. At this time, due to the restriction of the control wheel 41 and the control rod 42, the second drive shaft 32 cannot rotate, so the coil spring 31 cannot pull the push block 25 to move through the traction rope 33. At this time, the reciprocating screw 35 continues to rotate. The slide 34 moves away from the push block 25 under the action of the reciprocating screw 35. The slide 34 abuts against the push plate 44. The slide 34 pushes the push plate 44 to rotate around the third drive shaft 43. The movement of the push plate 44 causes the third drive shaft 43 to rotate. The rotation of the third drive shaft 43 causes the control rod 42 to rotate. The rotation of the control rod 42 releases the restriction on the control wheel 41. At this time, the second drive shaft 32 can rotate normally, and the insertion rod... 45 is not connected to the push block 25. Under the action of the coil spring 31, the coil spring 31 pulls the push block 25 to move. The movement of the push block 25 causes the toothed belt 24 to run. The running of the toothed belt 24 causes the second spur gear 26 to rotate. The rotation of the second spur gear 26 causes the first drive shaft 21 to rotate. The rotation of the first drive shaft 21 causes the first spur gear 23 to rotate. The rotation of the first spur gear 23 causes the first crown gear 22 to rotate. The rotation of the first crown gear 22 causes the cleaning roller 12 to rotate. The rotation of the cleaning roller 12 pushes the debris in the through groove 11 and pushes it out of the through groove 11. The fixing component and the control component 4 are used to limit the movement of the push block 25 to ensure that the push block 25 moves under the maximum force of the coil spring 31. This can ensure that the cleaning roller 12 applies force to the debris and improve the cleaning effect of the cleaning roller 12 on the severely blocked through groove 11.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
