Description

Technical Field

[0001] This invention relates to the field of road drainage technology, and more specifically, to a drainage system. Background Technology

[0002] Road surface drainage is a crucial aspect of ensuring road safety and extending its service life. It involves effectively removing water from the road surface and preventing water accumulation from damaging the roadbed and vehicles. Currently, in outdoor road drainage systems of building plazas and residential areas, when the pipes are blocked by layers of debris (such as waste paper and fallen leaves), drainage is significantly affected, easily causing water accumulation in a short period of time and affecting the passage of vehicles and pedestrians. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a drainage system that reduces the blockage of drainage pipes.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a drainage system, including a drainage device installed on the roadbed, the roadbed having a water pipe trench, the water pipe trench having a drain pipe installed, the drain pipe being connected to a drain pipe and an insert pipe, the drain pipe being connected to the insert pipe, the insert pipe being located inside the drain pipe, the top of the insert pipe being lower than the top of the drain pipe, the end of the drain pipe furthest from the drain pipe being higher than the top of the drain pipe, the insert pipe having a lifting rod installed, the lifting rod being inserted into the insert pipe, the lifting rod having a buoyancy block installed, the buoyancy block being located inside the insert pipe, the buoyancy block being able to float up and down to drive the lifting rod to move up and down, the upper end of the lifting rod having a lifting plate installed, the upper end of the lifting plate having a rod body two installed, the top of the drain pipe having a throttling plate, the throttling plate having multiple guide holes two, when the rod body two is at its lower limit position, the top of the rod body two is inserted into the guide hole two, when the rod body two moves upward, the upper end of the rod body two can extend out of the top of the guide hole two.

[0005] The present invention is further configured such that the second rod includes an extension rod located at the top, the cross-sectional dimension of the extension rod being larger than that of the second rod. When the second rod is located at the lower limit position, the extension rod is inserted into the second guide hole. When the second rod moves upward, the extension rod can extend out of the top of the second guide hole.

[0006] The invention is further configured such that the insertion tube has a flow channel one, which is located below the buoyancy block, and the lifting rod is also fixedly installed with a stop block, which is located below the buoyancy block. When the buoyancy block is at its lower limit position, the bottom of the buoyancy block closes the upper end of the flow channel one. The stop block is inserted into the flow channel one. When the buoyancy block floats upward, the stop block moves upward and can leave the upper end of the flow channel one, so that the flow channel one opens.

[0007] The invention is further configured such that the throttle plate is provided with a plurality of guide holes, and a rod is slidably installed on the inner wall of the guide hole. A rod body is also fixedly installed on the upper end of the lifting plate. The rod body can move upward to abut against the rod so that the rod moves upward.

[0008] The invention is further configured such that a limiting groove is provided on the inner wall of the flow guide hole, and extensions are provided on both sides of the top of the insertion rod. The extensions are inserted into the limiting groove, and the highest position of the insertion rod moving upward does not exceed the top of the flow guide hole.

[0009] The invention is further configured such that the diameter of the insertion rod is smaller than the inner diameter of the guide hole.

[0010] The present invention is further configured such that the insertion tube has a second flow channel, which is located at the bottom of the insertion tube.

[0011] The invention is further configured such that the roadbed includes a median strip and green belt areas and road surface located on both sides of the median strip, the road surface is provided with a water collection trough, the drain pipe is located below the water collection trough, the median strip is provided with a groove, and the end of the drain pipe away from the drain pipe is connected to the groove.

[0012] The invention is further configured such that the drain pipe includes an extension pipe located at the top, and a net is installed between the outer wall of the lifting plate and the inner wall of the extension pipe.

[0013] In summary, the present invention has the following beneficial effects:

[0014] 1. When water accumulates above the throttling plate, the liquid level rises, and the end of the insertion tube above the drain pipe is filled with water. The water flows into the insertion tube, causing the buoyancy block to rise. The second rod moves upward and extends out of the top of the throttling plate, so that the covering above the throttling plate is pushed open, thereby preventing the throttling plate from being covered by layers of debris and causing blockage.

[0015] 2. By moving rod one and rod two up and down, the flow guide holes one and two are cleared, reducing blockage. Since the insert rod and rod one are separate, the throttling plate can be lifted upwards for easy cleaning of debris from the drain pipe. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] like Figure 1 , Figure 2 As shown, this embodiment discloses a drainage system, including a drainage device installed on a roadbed 1. The roadbed 1 includes a median strip 11, green belt areas 12 located on both sides of the median strip 11, and a road surface 13. The median strip 11 forms a protrusion relative to the road surface 13. A groove 111 is provided on the side of the median strip 11 closest to the road surface 13, and a filter plate 15 is installed in the groove 111. A water collection trough 131 is provided on the side of the road surface 13 closest to the median strip 11. A pressure plate 14 is installed in the water collection trough 131 and inserted into the water collection trough 131. The pressure plate 14 has a through hole 141 that extends vertically through the pressure plate 14.

[0023] The roadbed 1 is equipped with a water pipe trench, and a drain pipe 2 is installed in the water pipe trench. The drain pipe 2 is located below the water collection tank 131, and the bottom of the drain pipe 2 is connected to the drainage pipe 3.

[0024] like Figure 1 , Figure 2 As shown, drain pipe 2 is connected to drain pipe 16 and insert pipe 6, with drain pipe 16 and insert pipe 6 connected. Specifically, one end of drain pipe 16 is connected to drain pipe 2, and the other end is connected to groove 111, allowing accumulated water to flow into drain pipe 16 through filter plate 15. Insert pipe 6 is located inside drain pipe 2 and includes extension pipe 62, which is connected to drain pipe 16. The top of insert pipe 6 is lower than the top of drain pipe 2, while the end of drain pipe 16 furthest from drain pipe 2 is higher than the top of drain pipe 2. Insert pipe 6 has a flow channel 61 at its bottom, which penetrates the bottom wall of insert pipe 6.

[0025] like Figure 1 , Figure 2As shown, the top of the drain pipe 2 is covered with a throttling plate 4. The throttling plate 4 is provided with multiple guide holes 41 and multiple guide holes 42. The guide holes 41 and multiple guide holes 42 are used to allow the accumulated water to flow into the drain pipe 2.

[0026] like Figure 2 As shown, a cover plate 7 is installed on the top of the insertion tube 6, and a lifting rod 5 is installed on the insertion tube 6. The lifting rod 5 is inserted into the insertion tube 6, and the upper end of the lifting rod 5 extends out of the cover plate 7. A buoyancy block 53 is installed on the lifting rod 5. The buoyancy block 53 is located inside the insertion tube 6. When the water level in the insertion tube rises, the buoyancy block 53 can float up. When the buoyancy block 53 floats up and down, it can drive the lifting rod 5 to move up and down synchronously.

[0027] A lifting plate 52 is installed at the upper end of the lifting rod 5. The drain pipe 2 includes an extension pipe 21 located at the top. The lifting plate 52 is located inside the extension pipe 21. A net bag 9 is installed between the outer peripheral wall of the lifting plate 52 and the inner wall of the extension pipe 21. The lifting plate 52 and the net bag 9 form an interception layer, which can intercept most of the solid waste above the lifting plate 52 and the net bag 9, preventing solid waste from entering the drain pipe 3 and causing blockage.

[0028] The upper end of the lifting plate 52 is fixedly installed with rod 1 521 and rod 2 522. Both rod 1 521 and rod 2 522 extend upward along the upper end surface of the lifting plate 52. Rod 1 521 is set one-to-one with the guide hole 1 41, and rod 2 522 is set one-to-one with the guide hole 2 42.

[0029] like Figure 2 As shown, when rod 2 522 is at its lower limit position, the top of rod 2 522 is inserted into guide hole 2 42. When rod 2 522 moves upward, the upper end of rod 2 522 can extend beyond the top of guide hole 2 42. Specifically, rod 2 522 includes an extension rod 5221 located at the top. The cross-sectional dimension of extension rod 5221 is larger than that of rod 2 522. When rod 2 522 is at its lower limit position, extension rod 5221 is inserted into guide hole 2 42. When rod 2 522 moves upward, extension rod 5221 can extend beyond the top of guide hole 2 42 to push open the blockage at the upper end of throttling plate 4, thereby ensuring smooth drainage. Figure 4 As shown, when the second rod 522 is at its upper limit position, the extension rod 5221 extends fully out of the second flow hole 42. At this time, the flowable cross section of the second flow hole 42 increases, which helps to drain water quickly.

[0030] like Figure 2 , Figure 3As shown, a cylindrical rod 8 is slidably installed on the inner wall of the flow guide hole 41. A limiting groove 411 is provided on the inner wall of the flow guide hole 41, and extensions 81 are provided on both sides of the top of the rod 8. The extensions 81 are inserted into the limiting groove 411. When the rod body 521 moves upward, it abuts against the rod 8, causing the rod 8 to move upward. When the rod body 521 moves downward, the rod 8 falls back under gravity. The diameter of the rod 8 is smaller than the inner diameter of the flow guide hole 41, and water flows through the gap between the outer wall of the rod 8 and the inner wall of the flow guide hole 41. The highest position of the upward movement of the rod 8 does not exceed the top of the flow guide hole 41 to prevent the rod 8 from detaching from the flow guide hole 41. The up-and-down movement of the rod 8 within the flow guide hole 41 reduces clogging and maintenance frequency.

[0031] Since the insertion rod 8 and the rod body 521 are separate, the throttling plate 4 can be lifted upwards to facilitate the cleaning of debris in the drain pipe 2.

[0032] like Figure 2 As shown, flow channel 61 is located below buoyancy block 53. A stop block 51 is also fixedly installed on the lifting rod 5. The stop block 51 is located below buoyancy block 53. When buoyancy block 53 is at its lower limit position, the bottom of buoyancy block 53 closes the upper end of flow channel 61, and the stop block 51 is inserted into flow channel 61. Figure 4 As shown, when the area above the throttling plate 4 is blocked by debris, making drainage difficult, the liquid level rises, and the accumulated water flows into the drain pipe 16 and the insertion pipe 6. The liquid level in the insertion pipe 6 rises, the buoyancy block 53 floats upward, and the baffle block 51 moves upward and can move away from the upper end of the flow channel 61, so that the flow channel 61 opens. Since the water level changes continuously over a certain period of time, when the water level drops and no longer flows into the drain pipe 16, the liquid level in the insertion pipe 6 drops rapidly due to the drainage effect of the flow channel 61, and the buoyancy block 53 moves downward. When the water level rises, water is squeezed into the drain pipe 16, and the buoyancy block 53 floats up again. When the buoyancy block 53 floats up and down, the rod body 521 and the rod body 522 move up and down synchronously to clear the flow guide hole 41 and the flow guide hole 42 and prevent them from becoming blocked.

[0033] The extension tube 62 is provided with a second flow channel 621, which is located at the bottom of the extension tube 62. The second flow channel 621 is a small drain hole used to slowly drain the water accumulated in the insertion tube 6. Since its drainage volume is very small, it has almost no effect when the insertion tube 6 is continuously filled with water. After the water is drained, the remaining water in the insertion tube 6 is slowly discharged from the second flow channel 621 so that the buoyancy block 53 drops to the lower limit position.

All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
