Description

Technical Field

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

[0002] A bar screen inlet is a surface water collection device installed on roads, ditches, or in low-lying areas. Its core feature is a bar screen made of metal (or other materials) strips, covering the inlet. It allows surface water to flow through the gaps in the bar screen into the collection well below and into underground drainage pipes, while intercepting larger floating objects and solid debris to prevent pipe blockage.

[0003] Currently, the common bar screen inlets on the market are usually set up on the roadside. Under the scouring of rainwater, the filter holes on the bar screen inlets are easily blocked by mud, which leads to water accumulation. At the same time, since roads are generally long, a lot of bar screen inlets need to be set up. When a sudden rainstorm occurs, it is difficult for staff to reach each bar screen inlet in time to clean it, resulting in water accumulation on the road. Water accumulation on the road can cause wheels to slip, and in more serious cases, it may cause traffic accidents.

[0004] Therefore, how to quickly unclog the inlet of the bar screen is a problem that needs to be solved. Summary of the Invention

[0005] The purpose of this invention is to provide a road and bridge drainage device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a road and bridge drainage device, comprising:

[0007] The frame and the top cover located on the top of the frame, the filter plate for filtration is fixed inside the frame, the cylinder that can pass through the filter holes on the filter plate is provided inside the frame, the bottom of the cylinder is provided with a lifting mechanism that can drive the cylinder to rise and fall, the cylinder rising and falling facilitates the unblocking of the filter plate.

[0008] Preferably, the lifting mechanism includes a support plate fixed inside the frame, a motor fixed on the support plate, a rotating plate fixedly connected to the output end of the motor through the support plate, a rotating rod rotatably connected to the rotating plate via a rotating shaft, a top rod rotatably connected to the rotating rod via a rotating shaft, a movable plate fixed to the top of the top rod, and a cylinder fixedly connected to the top of the movable plate. The motor drives the rotating plate to rotate, the rotating plate drives the rotating rod to rotate, the rotating rod drives the movable plate to rise and fall, and the movable plate drives the cylinder to rise and fall. The cylinder penetrates the filter plate to unclog the filter plate and prevent the filter plate from being blocked by sludge.

[0009] Preferably, the bottom of the filter plate is fixed with an inclined plate, and a through hole is provided on the inclined plate. The cylinder can pass through the through hole, and the filter hole and the through hole have the same diameter, which facilitates the cylinder to pass through the through hole and the filter hole.

[0010] Preferably, two inclined plates are fixed at the bottom of the filter plate, and the two inclined plates are symmetrically arranged. The height of the two inclined plates extends from the middle of the filter plate to the edge of the filter plate. The two inclined plates can guide the water flow, making it easier for the water to flow down the inclined plates.

[0011] Preferably, the top of the cylinder is sloped, and the slope is the same as that of the inclined plate, which facilitates the formation of a smooth slope between the cylinder and the inclined plate, preventing the cylinder from obstructing the water flow and preventing the water from flowing downward from the through hole.

[0012] Preferably, a fixing plate is fixed inside the frame, and a top block is fixed on the top of the fixing plate, with the fixing plate and the top block supporting the movable plate.

[0014] Preferably, the height at which the cylinder can move upward is less than the height of the top cover and the filter plate, so as to prevent the cylinder from moving upward beyond the top plate and causing harm to vehicles or pedestrians on the road.

[0015] Preferably, baffles are fixed on both sides of the movable plate.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] The motor drives the rotating plate to rotate, which in turn drives the rotating rod to rotate. The rotating rod then drives the moving plate to rise and fall, which in turn drives the cylinder to rise and fall. The cylinder passes through the filter plate, clearing the filter plate and preventing it from being clogged by sludge. Attached Figure Description

Detailed Implementation

[0024] 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.

[0025] Please see Figures 1 to 5 One embodiment of the present invention provides a road and bridge drainage device, comprising:

[0026] The frame 1 and the top cover 2 located on the top of the frame 1 are provided. A filter plate 3 for filtration is fixed inside the frame 1. A cylinder 601 that can pass through the filter holes 4 on the filter plate 3 is provided inside the frame 1. A lifting mechanism 6 that can drive the cylinder 601 to rise and fall is provided at the bottom of the cylinder 601. The rising and falling of the cylinder 601 facilitates the unblocking of the filter plate 3.

[0027] When the filter holes 4 on the filter plate 3 are clogged with sludge, it is generally necessary for staff to clean the filter plate 3 with hand cleaning tools, which is quite troublesome. In addition, when there is a sudden rainstorm, the staff may not be able to get to the scene in time, and the sludge clogging the filter plate 3 will cause water accumulation.

[0028] The lifting mechanism 6 includes a support plate 606 fixed inside the frame 1. A motor 610 is fixed on the support plate 606. The output end of the motor 610 passes through the support plate 606 and is fixedly connected to a rotating plate 607. A rotating rod 608 is rotatably connected to the rotating plate 607 via a rotating shaft. A top rod 609 is rotatably connected to the rotating rod 608 via a rotating shaft. A movable plate 602 is fixed to the top of the top rod 609. The top of the movable plate 602 is fixedly connected to a cylinder 601. The motor 610 drives the rotating plate 607 to rotate, which in turn drives the rotating rod 608 to rotate. The rotating rod 608 drives the movable plate 602 to rise and fall, which in turn drives the cylinder 601 to rise and fall. The cylinder 601 passes through the filter plate 3 to clear the filter plate 3 and prevent it from being blocked by sludge.

[0029] Water may flow directly downwards after passing through filter plate 3. Although motor 610 is waterproof, the power cord and other components are more easily damaged if soaked in water for a long time. Furthermore, a sloping plate 5 is fixed at the bottom of filter plate 3. A through hole 7 is provided on the sloping plate 5. The cylinder 601 can pass through the through hole 7. The filter hole 4 and the through hole 7 have the same diameter, which facilitates the cylinder 601 to pass through the through hole 7 and the filter hole 4.

[0030] It is worth noting that two inclined plates 5 are fixed at the bottom of the filter plate 3, and the two inclined plates 5 are symmetrically arranged. The height of the two inclined plates 5 extends from the middle of the filter plate 3 to the edge of the filter plate 3. The two inclined plates 5 can guide the water flow, making it easier for the water to flow down the inclined plates 5.

[0031] Furthermore, the top of the cylinder 601 is set with a slope, and the slope is the same as that of the inclined plate 5. This makes it easy for the cylinder 601 and the inclined plate 5 to form a smooth slope, which avoids the cylinder 601 from blocking the water flow and also prevents the water from flowing downward from the through hole 7.

[0032] In addition, a fixing plate 605 is fixed inside the frame 1, and a top block 604 is fixed on the top of the fixing plate 605. The fixing plate 605 and the top block 604 support the moving plate 602.

[0033] The top cover 2 includes a top plate 201 located on top of the frame 1. A rectangular hole 202 is provided on the top plate 201. An insert block 203 is fixed at the bottom of the top plate 201. A slot 204 is provided on the top of the frame 1. The insert block 203 matches the slot 204. The insert block 203 can be inserted into the slot 204, which facilitates the removal and installation of the top plate 201. The top plate 201 is kept horizontal with the ground, which improves road safety.

[0034] Meanwhile, the cylinder 601 can be moved upward to a height less than that of the top cover 2 and the filter plate 3, so as to prevent the cylinder 601 from moving upward beyond the top plate 201 and causing damage to vehicles or pedestrians on the road.

[0035] Preferably, baffles 603 are fixed on both sides of the movable plate 602 to block the water flow and prevent water from splashing onto the motor 610.

[0036] When cleaning the sludge accumulated on the filter plate 3 during operation, lift the top cover 2 upwards and remove it from the frame 1 to clean the filter plate 3. If the staff cannot arrive in time due to the long distance, the motor 610 can be turned on. The motor 610 drives the rotating plate 607 to rotate, the rotating plate 607 drives the rotating rod 608 to rotate, the rotating rod 608 drives the moving plate 602 to rise and fall, the moving plate 602 drives the cylinder 601 to rise and fall, the cylinder 601 penetrates the filter plate 3 to unclog the filter plate 3, prevent the filter plate 3 from being blocked by sludge, and prevent water accumulation caused by the staff not being able to arrive in time.

[0037] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
