Description

Technical Field

[0001] The utility model relates to the technical field of road drainage, in particular to a road drainage device. Background Art

[0002] Road drainage refers to the measures taken to remove water from the road surface. Typically, road drainage is achieved by setting up drainage channels on the roadside. Covers are also installed at the grooves of the drainage channels to block pedestrians and vehicles from falling into them.

[0003] However, traditional covers are placed directly on the drains, so they are very easy to lose. If the cover is lost, pedestrians and vehicles may easily fall into the drains. Utility Model Content

[0004] The present application provides a road drainage device, which prevents the cover plate from being lost by cooperating with the insertion rod and the insertion hole.

[0005] The road drainage device provided in this application adopts the following technical solution:

[0006] A road drainage device includes a base and a cover plate buried above a drainage channel, the base is provided with a receiving groove for accommodating the cover plate, the bottom wall of the receiving groove is provided with a through groove connected to the drainage channel, the cover plate is provided with multiple drainage channels, and the multiple drainage channels are all connected to the receiving groove, the bottom of the cover plate is slidably connected to a plug rod, the plug rod is adjacent to one of the drainage channels, and the side wall of the through groove is provided with a socket for plugging with the plug rod.

[0007] By adopting the above technical solution, the base is buried on the drainage channel during construction, and then the cover plate is placed in the receiving groove and the insertion rod is aligned with the insertion hole. The construction worker's fingers are then passed through the drainage channel and against the insertion rod, and then the insertion rod is forcefully pushed into the insertion hole. In this way, the cover plate can be confined in the receiving groove, thereby preventing the cover plate from being lost.

[0008] Preferably, a sleeve is provided on the bottom of the cover plate, the insertion rod is slidably connected in the sleeve, a pull rod is provided on the side of the insertion rod facing the bottom wall of the sleeve, the pull rod extends out of the sleeve at one end away from the insertion rod and is connected to a pull ring, a first spring is sleeved on the insertion rod, the first spring is located in the sleeve, one end of the first spring is in conflict with the bottom wall of the sleeve, the other end of the first spring is in conflict with the insertion rod, a guide slope is provided at the bottom of the insertion rod, when the insertion rod is entered into the through slot, the guide slope is in conflict with the top of the through slot, and when the insertion rod is plugged into the socket, the first spring is in a compressed state.

[0009] By adopting the above technical solution, when the cover is placed into the receiving groove, the guiding bevel will first come into contact with the top of the through groove. As the cover continues to move, the insertion rod will move into the sleeve under the action of the guiding bevel and compress the first spring. When the cover is completely placed into the receiving groove, the insertion rod will align with the insertion hole, and the first spring will rebound to drive the insertion rod into the insertion hole. At the same time, the first spring will press the insertion rod into the insertion hole to prevent the insertion rod from being dislodged from the insertion hole. When it is necessary to lift the cover, the construction worker's fingers pass through the drainage channel and hook the pull ring, then pull the pull ring to pull the insertion rod out of the insertion hole through the pull rod. At this time, the cover can be removed from the receiving groove.

[0010] Preferably, a filter screen is provided in the through groove, and the filter screen is tilted, with an end of the filter screen close to the insertion rod being higher than an end of the filter screen away from the insertion rod.

[0011] By adopting the above technical solution, the filter can prevent fallen leaves and other debris from falling into the drain. The inclined setting of the filter is to allow fallen leaves and other debris to be collected on the lower end of the filter under the erosion of rainwater, preventing fallen leaves and other debris from accumulating on the surface of the filter and affecting the drainage performance of the filter.

[0012] Preferably, a collecting groove is provided on the top surface of the base, a through groove communicating with the through groove is provided on the side wall of the collecting groove, and an end of the filter screen away from the insertion rod is located in the through groove.

[0013] By adopting the above technical solution, fallen leaves and other garbage will be uniformly collected in the collection trough, making it easier to clean up the garbage later.

[0014] Preferably, the end of the filter screen away from the insertion rod is rotatably connected in the through groove, the end of the filter screen close to the insertion rod is in conflict with the side wall of the through groove, and the cover plate is also provided with a driving component for driving the filter screen to rotate.

[0015] By adopting the above technical solution, the driving component is used to flip the filter so that the garbage on the filter is poured into the collection tank, further emptying the garbage on the filter and ensuring the filtering performance of the filter.

[0016] Preferably, the driving assembly includes a slide groove opened on the side wall of the through groove, a connecting rod provided at the bottom of the cover plate and slidably connected in the slide groove, a limit block provided at the bottom of the connecting rod, a second spring provided on the connecting rod, and a lifting block provided on the limit block, one end of the lifting block is rotatably connected to the limit block, the other end of the lifting block extends out of the slide groove, one end of the second spring is connected to the pull rod, and the other end of the second spring is connected to the lifting block, the second spring is always in a compressed state, and when the cover plate is located in the accommodating groove, the end of the lifting block away from the limit block is located below the filter screen, and the second spring presses the lifting block against the limit block.

[0017] By adopting the above technical solution, when the cover plate is removed from the receiving slot, it moves upward, carrying with it the connecting rod, the stopper, and the lifting block. During this movement, the lifting block collides with the filter screen, causing it to flip over, causing the garbage on the filter screen to be dumped into the collection trough. Eventually, the lifting block moves until it no longer interferes with the filter screen, at which point the filter screen repositions itself under the action of gravity. When the cover plate is replaced in the receiving slot, the connecting rod is first inserted into the chute, and then the cover plate is slowly lowered into the receiving slot. When the cover plate is placed into the receiving slot, the connecting rod is first aligned and inserted into the chute, and then the cover plate is slowly lowered, causing the lifting block to also move downward. During this process, the lifting block first interferes with the filter screen. As the lifting block continues to move, it flips over and moves into the chute. This flipping of the lifting block compresses the second spring. When the lifting block no longer interferes with the filter screen, the second spring rebounds, causing the lifting block to rotate, pressing it against the stopper again and allowing one end of the lifting block to extend out of the chute.

[0018] Preferably, the bottom wall of the collecting trough is funnel-shaped, and a through hole communicating with the through trough is provided at the lowest point of the bottom wall of the collecting trough. The through hole is provided with an anti-clogging portion for preventing garbage from clogging the through hole.

[0019] By adopting the above technical solution, rainwater entering the collection trough can also be discharged back into the trough through the through hole, preventing rainwater from accumulating in the collection trough and causing garbage such as fallen leaves to be soaked and stink.

[0020] Preferably, the anti-clogging portion includes a conical filter cover and a connecting pipe provided at the bottom of the conical filter cover, and the connecting pipe is threadedly connected in the through hole.

[0021] By adopting the above technical solution, the filter cover can prevent garbage from falling into the through hole and thus prevent the through hole from being blocked. At the same time, the filter cover can be disassembled and cleaned to ensure the filtering performance of the filter cover.

DETAILED DESCRIPTION

[0033] The following is a further detailed description of the present application in conjunction with the accompanying drawings to make the technical solution of the present application easier to understand and grasp.

[0034] Reference Figure 1 and Figure 2 A road drainage device according to this embodiment includes a base 1 buried above a drainage channel. A receiving groove 11 is defined on the top surface of the base 1, and a cover plate 2 is placed within the receiving groove 11. A through groove 12 is defined vertically on the bottom wall of the receiving groove 11, connecting to the drainage channel. The cover plate 2 is defined with multiple drainage channels 21, all of which are connected to the receiving groove 11.

[0035] Reference Figure 1-Figure 3 A sleeve 31 is fixedly connected to the bottom of the cover plate 2 and is located adjacent to one of the drainage channels 21. A socket 13 is formed on the sidewall of the through-slot 12, facing the opening of the sleeve 31. A rod 22 is horizontally slidably connected to the sleeve 31 and engages with the socket 13. A pull rod 32 is fixed to the side of the rod 22 facing the bottom wall of the sleeve 31. The end of the pull rod 32, away from the rod 22, extends out of the sleeve 31 and is connected to a pull ring 33.

[0036] Reference Figure 3A first spring 34 is sleeved on the insertion rod 22, and the first spring 34 is located in the sleeve 31. One end of the first spring 34 conflicts with the bottom wall of the sleeve 31, and the other end of the first spring 34 conflicts with the insertion rod 22. A guiding slope 221 is provided at the bottom of the insertion rod 22. When the insertion rod 22 is inserted into the through groove 12, the guiding slope 221 conflicts with the top of the through groove 12. When the insertion rod 22 is plugged into the socket 13, the first spring 34 is in a compressed state.

[0037] Reference Figure 1 、 Figure 2 and Figure 4 A collection trough 15 is also provided on the top surface of the base 1. A through-trough 16 communicating with the through-trough 12 is provided on the sidewall of the collection trough 15. A removable cover plate 6 is installed on the top of the collection trough 15 to prevent rainwater from entering the collection trough 15. A filter screen 14 is rotatably connected to the through-trough 16. The other end of the filter screen 14 extends out of the through-trough 16 and abuts against the sidewall of the through-trough 12. The end of the filter screen 14 abutting against the sidewall of the through-trough 12 is higher than the end of the filter screen 14 located within the through-trough 16.

[0038] Reference Figure 1 、 Figure 2 and Figure 4 The bottom wall of the collecting trough 15 is funnel-shaped. A through hole 17 communicating with the through trough 12 is formed at the lowest point of the bottom wall of the collecting trough 15. The through hole 17 is provided with an anti-clogging portion 5 for preventing garbage from clogging the through hole 17. The anti-clogging portion 5 includes a conical filter cover 51 and a connecting pipe 52 fixed to the bottom of the conical filter cover 51. The connecting pipe 52 is threadedly connected to the through hole 17.

[0039] Reference Figure 1 、 Figure 5 and Figure 6 The cover plate 2 is further provided with two sets of driving components 4 for driving the filter screen 14 to rotate. The two sets of driving components 4 are respectively arranged on both sides of the cover plate 2. A set of driving components 4 includes a slide groove 41 opened on the side wall of one side of the through groove 12, a connecting rod 42 fixed to the bottom of the cover plate 2 and slidably connected in the slide groove 41 along the vertical direction, a limit block 43 fixed to the bottom of the connecting rod 42, a second spring 44 fixed on the connecting rod 42, and a lifting block 45 provided on the limit block 43. One end of the lifting block 45 is rotatably connected to the limit block 43, and the other end of the lifting block 45 extends out of the slide groove 41. One end of the second spring 44 is connected to the pull rod 32, and the other end of the second spring 44 is connected to the lifting block 45. The second spring 44 is always in a compressed state. When the cover plate 2 is located in the accommodating groove 11, the ends of the two lifting blocks 45 away from the corresponding limit blocks 43 are both located below the filter screen 14. The two second springs 44 press the lifting blocks 45 on the limit blocks 43, and the two limit blocks 43 are completely located in the two slide grooves 41.

[0040] Reference Figures 1-6 The specific disassembly and assembly steps of the cover plate 2 of this application are as follows:

[0041] When inserting the cover plate 2 into the receiving slot 11, first align the two connecting rods 42 and insert them into the slide slots 41, then slowly lower the cover plate 2. As the cover plate 2 moves downward, the guiding slope 221 will contact the top of the through slot 12. As the cover plate 2 continues to move, the insertion rod 22 will move into the sleeve 31 and compress the first spring 34. When the cover is fully inserted into the receiving slot 11, the insertion rod 22 will align with the insertion hole 13, and the first spring 34 will rebound to drive the insertion rod 22 into the insertion hole 13. At the same time, the first spring 34 presses the insertion rod 22 into the insertion hole 13, preventing the insertion rod 22 from being dislodged from the insertion hole 13, thereby preventing the cover plate 2 from being lost.

[0042] Similarly, as the cover plate 2 moves downward, the two lifting blocks 45 first come into contact with the filter screen 14. As the two lifting blocks 45 continue to move, they flip over and move into the two chute slots 41. This flipping of the two lifting blocks 45 compresses the two second springs 44. When the two lifting blocks 45 no longer come into contact with the filter screen 14, the two second springs 44 rebound, pressing the two lifting blocks 45 against the stop blocks 43 again, allowing the ends of the two lifting blocks 45 away from the corresponding stop blocks 43 to extend out of their corresponding chute slots 41.

[0043] When the cover plate 2 needs to be taken out of the receiving groove 11, the construction worker's fingers pass through the drainage channel 21 and hook the pull ring 33, then pull the pull ring 33 through the pull rod 32 to pull the insertion rod 22 out of the socket 13. At this time, the cover plate 2 can be taken out of the receiving groove 11 in the vertical direction.

[0044] When the cover plate 2 is removed from the receiving slot 11, it moves upward, along with the two connecting rods 42, the two stoppers 43, and the two lifting blocks 45. During this movement, the two lifting blocks 45 collide with the filter 14 and cause the filter 14 to flip over, causing the garbage on the filter 14 to fall into the collection slot 15. Eventually, the lifting blocks 45 move until they no longer interfere with the filter 14, and the filter 14 returns to its original position under the action of gravity.

[0045] Of course, the above are only typical examples of the present application. In addition, the present application may have many other specific implementation methods. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present application.
