Description

Technical Field

[0001] This utility model relates to the field of bridge drainage technology, specifically a bridge deck drainage pipe for bridges. Background Technology

[0002] To quickly drain water from bridge decks and prevent rainwater from accumulating on the bridge surface and seeping into the beams, thus affecting the bridge's durability, bridge designs include longitudinal and transverse slope drainage, as well as a certain number of drainage pipes on the bridge deck to form a complete drainage system. Drainage pipes are generally made of metal, reinforced concrete, or transverse. Traditional bridge deck drainage pipes may encounter situations with excessive water flow, and the debris inside must be treated promptly, otherwise it will affect the normal operation of the system.

[0003] Existing technology, such as publication number CN215887914U, provides a bridge deck drainage pipe, including a conveying pipe, a drainage mechanism fixedly connected to the upper surface of the conveying pipe, a support column fixedly connected to the upper surface of the drainage mechanism, and a filter mechanism fixedly connected to the end of the support column away from the drainage mechanism. In this invention, by configuring the pipe body and expansion joints, the device itself has the ability to withstand hot and cold environments, avoiding structural damage caused by alternating hot and cold temperatures, thus improving the durability of the device. Furthermore, by configuring a pressure regulating mechanism, the device itself has the ability to maintain pressure balance inside the conveying pipe, ensuring the water flow rate inside the conveying pipe. By configuring a waste treatment device, the device itself has the ability to perform simple filtration of the water flow through small holes on the surface of the load-bearing plate, and a motor-driven push rod cleans the waste from the surface of the load-bearing plate.

[0004] The current solution incorporates a waste treatment device that uses small holes on the surface of the load-bearing plate to perform simple filtration of the water flow. An electric motor drives a push rod to clean the waste from the plate surface, achieving automatic waste removal. However, in actual use, when blockages occur during bridge drainage, the suction generated at the drainage holes during cleaning causes the scraped-off waste and impurities to be quickly re-drawn into the holes by the water flow, easily leading to secondary blockages. Therefore, we propose a bridge deck drainage pipe for bridges. Utility Model Content

[0005] The purpose of this utility model is to provide a bridge deck drainage pipe for bridges. This bridge deck drainage pipe solves the problem that the drainage holes themselves generate suction during drainage, which causes dirt and impurities to be sucked into the drainage holes under the action of water flow, easily causing blockage.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A bridge deck drainage pipe for bridges includes a drainage pipe with a collection mechanism inside the drainage pipe;

[0008] The collection mechanism includes a collection pool, which is located below the top of the drain pipe. A boss is fixedly connected to the bottom of the collection pool, and a filter screen is fixedly connected to the top of the boss.

[0009] The top of the filter screen is equipped with an automatic unclogging mechanism for cleaning clogged filter screens.

[0010] Preferably, the top of the collection pool is detachably connected to a pool cover, and the top of the drain pipe is fixedly connected to a fence.

[0011] Preferably, the automatic unclogging mechanism includes two sets of slides. The inner wall of the collection tank is fixedly connected to the slides on both sides of the top of the filter screen. The top of the two sets of slides is slidably connected to a scraper, and the scraper is in contact with the top of the filter screen.

[0012] Preferably, an overflow pipe is fixedly connected to the outer wall of the collection tank above the filter screen, and a transfer chamber is fixedly connected to the end of the overflow pipe away from the collection tank. A manifold is fixedly connected to the bottom of the transfer chamber, and the manifold communicates with the interior of the drain pipe.

[0013] Preferably, an intercepting net is fixedly connected to one end of the overflow pipe inside the collection pool, and the intercepting net is set at an angle.

[0014] Preferably, the scraper is fixedly connected to both ends with traction ropes. The end of the traction rope inside the collection pool is connected to a coil spring connected to the inner wall of the collection pool, and the end of the traction rope away from the coil spring extends to the outside of the collection pool.

[0015] Preferably, the inner wall of the transfer chamber is rotatably connected to a water wheel via a rotating shaft, and the water wheel is in contact with the inner wall of the transfer chamber. The two ends of the rotating shaft extend to the outside of the transfer chamber, and the outer wall of the rotating shaft is fixedly connected to a traction rope at a corresponding position.

[0016] By employing the above technical solution, this utility model provides a bridge deck drainage pipe for bridges. It possesses at least the following beneficial effects:

[0017] I. This utility model, by installing a grid mesh on the top of the drain pipe, can prevent larger foreign objects from the road surface from entering the drain pipe. When the accumulated water enters the collection tank through the grid mesh, it will be filtered and intercepted again by the filter screen, preventing some impurities in the water from accumulating in the drain pipe and causing blockage. The filtered and intercepted impurities will be scraped off by the automatic anti-blockage mechanism. Since the filter screen is installed on the protrusion, the scraped impurities will fall to the bottom of the collection tank, thus avoiding the problem of secondary blockage caused by the suction generated at the filter screen during drainage due to the water flow.

[0018] II. When the filter screen is clogged, the continuously flowing water enters the collection tank and overflows from the overflow pipe into the transfer chamber. It then flows into the drain pipe through the manifold to assist in drainage and reduce the pressure on the drain pipe. As the water overflows from the overflow pipe into the transfer chamber, the water continuously entering the transfer chamber drives the water wheel to rotate under the action of gravity. When the water wheel rotates, the shaft connected to it will wind up the traction rope, thereby pulling the scraper connected to the traction rope to slide on the slide to facilitate cleaning of the filter screen. When the filter screen is cleared, the drainage returns to normal, and no more water overflows into the transfer chamber. At this time, the scraper will be pulled back to its original position under the action of the coil spring so that it can be cleaned next time, thus achieving the purpose of automatic cleaning.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] A bridge deck drainage pipe used in bridges, such as Figure 1 - Figure 4 As shown, the system includes a drain pipe 1, an internal collection mechanism 3, a collection pool 31, and a collection pool 31 located below the top of the drain pipe 1. A boss 32 is fixedly connected to the bottom of the collection pool 31, and a filter screen 33 is fixedly connected to the top of the boss 32. An automatic unclogging mechanism 2 is provided on the top of the filter screen 33 for cleaning the clogged filter screen 33. A pool cover 34 is detachably connected to the top of the collection pool 31, and a fence 4 is fixedly connected to the top of the drain pipe 1.

[0027] In this embodiment, by setting a fence 4 on the top of the drain pipe 1, larger foreign objects on the road can be prevented from entering the drain pipe 1. When the accumulated water enters the collection tank 31 from the fence 4, it will be filtered and intercepted again by the filter screen 33 to prevent some impurities in the accumulated water from accumulating in the drain pipe 1 and causing blockage. The filtered and intercepted impurities will be scraped off by the automatic unblocking mechanism 2. Since the filter screen 33 is installed on the boss 32, the scraped impurities will fall into the bottom of the collection tank 31, thereby avoiding the problem of secondary blockage caused by the suction generated at the filter screen 33 during drainage due to the water flow.

[0028] like Figure 2 , Figure 3 As shown, preferably, the automatic unblocking mechanism 2 includes two sets of slides 21. The inner wall of the collection tank 31 is fixedly connected to the slides 21 on both sides of the top of the filter screen 33. The top of the two sets of slides 21 is slidably connected to scrapers 22, and the scrapers 22 are in contact with the top of the filter screen 33. The outer wall of the collection tank 31 is fixedly connected to the overflow pipe 23 above the filter screen 33. The end of the overflow pipe 23 away from the collection tank 31 is fixedly connected to the transfer chamber 24. The bottom of the transfer chamber 24 is fixedly connected to the manifold 25, and the manifold 25 is connected to the inside of the drain pipe 1.

[0029] In this embodiment, when the filter screen 33 is clogged, the continuously injected water enters the collection tank 31 and overflows from the overflow pipe 23 into the transfer chamber 24, and then flows into the drain pipe 1 through the manifold 25 to assist in drainage and reduce the drainage pressure of the drain pipe 1.

[0030] like Figure 2 , Figure 3 As shown, preferably, one end of the overflow pipe 23 inside the collection pool 31 is fixedly connected to an intercepting net 231, and the intercepting net 231 is inclined. Both ends of the scraper 22 are fixedly connected to traction ropes 27. One end of the traction rope 27 inside the collection pool 31 is connected to a coil spring 28 connected to the inner wall of the collection pool 31, and the end of the traction rope 27 away from the coil spring 28 extends to the outside of the collection pool 31. The inner wall of the transfer chamber 24 is rotatably connected to a water wheel 26 through a rotating shaft 261, and the water wheel 26 contacts the inner wall of the transfer chamber 24. Both ends of the rotating shaft 261 extend to the outside of the transfer chamber 24, and the outer wall of the rotating shaft 261 is fixedly connected to the corresponding traction rope 27.

[0031] In this embodiment, when the accumulated water overflows from the overflow pipe 23 and flows into the transfer chamber 24, the water continuously entering the transfer chamber 24 drives the water wheel 26 to rotate under the action of gravity. When the water wheel 26 rotates, the shaft 261 connected to it will wind up the traction rope 27, thereby pulling the scraper 22 connected to the traction rope 27 to slide on the slide rail 21 to facilitate cleaning of the filter screen 33. When the filter screen 33 is cleared, the drainage returns to normal, and no more water overflows into the transfer chamber 24. At this time, the scraper 22 will be pulled back to its original position under the action of the coil spring 28 so that it can be cleaned next time, thereby achieving the purpose of automatic cleaning.

[0032] In use, this utility model discloses a bridge deck drainage pipe. A mesh screen 4 is installed at the top of the drainage pipe 1 to prevent large foreign objects from entering. When water flows from the mesh screen 4 into the collection tank 31, it is filtered again by a filter screen 33. When the filter screen 33 becomes clogged, the continuously flowing water enters the collection tank 31 and overflows from the overflow pipe 23 into the transfer chamber 24. From there, it flows into the drainage pipe 1 through the manifold 25 to assist drainage and reduce the pressure on the drainage pipe 1. As water overflows from the overflow pipe 23 into the transfer chamber 24, the water continuously entering the transfer chamber 24 drives the waterwheel 26 to rotate under gravity. When the shaft 261 connected to it is turned up, the traction rope 27 will be wound up, thereby pulling the scraper 22 connected to the traction rope 27 to slide on the slide rail 21 to facilitate cleaning of the filter screen 33. When the filter screen 33 is cleared, the drainage returns to normal and no more water overflows into the transfer chamber 24. At this time, the scraper 22 will be pulled back to its original position under the action of the coil spring 28. Since the filter screen 33 is installed on the boss 32, the scraped impurities will fall into the bottom of the collection pool 31, thereby avoiding the problem of secondary blockage caused by the suction generated at the filter screen 33 during drainage.
