Description

Technical Field

[0001] This utility model relates to the field of drainage equipment technology, and in particular to a rapid drainage device for bridges. Background Technology

[0002] As an important transportation infrastructure, the safety and normal use of bridges are of paramount importance. Among the many factors affecting bridge performance, drainage is a key aspect. If water cannot be drained from bridges in time during rainfall, it will cause a series of problems. Water accumulation will erode the bridge pavement layer, leading to damage and peeling of the pavement material and shortening the service life of the pavement layer. Long-term water accumulation may also seep into the main structure of the bridge, causing structural damage such as steel corrosion and reduced concrete strength, affecting the bridge's load-bearing capacity and durability. Water accumulation on bridges will reduce the friction of the road surface, increasing the danger of vehicle driving, especially on curves and downhill sections, which can easily cause vehicles to skid, lose control, and cause traffic accidents.

[0003] Traditional bridge drainage systems only use drainage holes and simple drainage pipes. However, due to the lack of corresponding discharge mechanisms, these simple devices accumulate impurities inside after prolonged operation, affecting drainage efficiency and even clogging the drainage pipes, rendering them inoperable. This results in water accumulation on the bridge not being discharged in a timely manner, creating certain safety hazards.

[0004] Therefore, there is an urgent need to provide a rapid drainage device for bridges to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a bridge rapid drainage device.

[0006] To solve the above-mentioned technical problems, the present invention provides a bridge rapid drainage device, including a drainage pipe, an installation pipe fixedly connected to the top of the drainage pipe, a protective cover installed on the top of the installation pipe, and multiple filter holes opened on the top of the protective cover.

[0007] A funnel-shaped filter tube is installed inside the drain pipe near the top. A filter plate is installed inside the funnel-shaped filter tube. A sewage pipe is fixedly connected to the bottom of the funnel-shaped filter tube. A discharge mechanism is set inside the drain pipe near the sewage pipe. A guide plate is installed inside the sewage pipe.

[0008] The present invention is further configured such that: the discharge mechanism includes a mounting block installed on the outer wall of the drain pipe, a drive motor is installed inside the mounting block, a first conical tooth is installed at the output end of the drive motor, a second conical tooth is rotatably connected to the outer wall of the first conical tooth, a first connecting rod is installed at the top of the second conical tooth, a first auger shaft is fixedly connected to the top of the first connecting rod, a rotating rod is fixedly connected to the top of the first auger shaft, two scrapers are installed on the outer wall of the rotating rod, a third conical tooth is rotatably connected to the outer wall of the second conical tooth, a second connecting rod is fixedly connected to the other side of the third conical tooth, and a second auger shaft is fixedly connected to the other end of the second connecting rod.

[0009] With the above technical solution, when the device drains water, larger impurities in the flowing water are blocked by the protective cover, while smaller impurities enter the device with the water flow and are blocked by the funnel-shaped filter tube and filter plate. The filtered water is drained through the drain hole. After the impurities on the filter plate accumulate to a certain amount, the drive motor starts to run, driving the first conical tooth to rotate. The rotation of the first conical tooth drives the second conical tooth to rotate, which in turn drives the first auger shaft to rotate. The rotation of the first auger shaft drives the two scrapers to rotate through the rotating rod. The two scrapers discharge the impurities on the filter plate through the through holes of the filter plate. The fallen impurities are discharged into the sewage pipe through the first auger shaft. The rotation of the second conical tooth also drives the third conical tooth to rotate, which drives the second auger shaft to rotate, discharging the impurities inside the sewage pipe.

[0010] The present invention is further configured such that the first conical tooth meshes with the second and third conical teeth.

[0011] Through the above technical solution, the meshing of multiple bevel teeth can make the force more evenly distributed in the transmission system. When the power is transmitted from the first bevel tooth, it can be distributed to different transmission paths through meshing with the second and third bevel teeth, avoiding excessive local stress and thus improving the load-bearing capacity of the entire transmission system.

[0012] The present invention is further configured such that: the top of the filter plate has a through hole corresponding to the scraper.

[0013] With the above technical solution, impurities tend to accumulate on the filter plate during the filtration process. The presence of through holes allows the scraper to act directly on the surface of the filter plate. When the scraper moves, it can push away the impurities accumulated on the filter plate through the through holes, preventing impurities from forming a thick accumulation layer on the filter plate and causing blockage, thereby ensuring the continuous and efficient operation of the filtration process.

[0014] The present invention is further configured such that both the first auger shaft and the second auger shaft are made of stainless steel.

[0015] Through the above technical solutions, stainless steel has good chemical corrosion resistance, which prevents the auger shaft from being damaged by corrosion, thereby extending its service life.

[0016] The present invention is further configured such that the outer walls of both the first auger shaft and the second auger shaft are attached to the inner wall of the sewage pipe.

[0017] Through the above technical solution, during the process of the auger shaft rotating to discharge debris, the debris can be effectively pushed forward, reducing the residue of debris in the sewage pipe. This ensures that as much debris as possible is transported to the designated location, improving the efficiency of debris discharge.

[0018] The present invention is further configured such that: the top of the guide plate has a hole corresponding to the first connecting rod.

[0019] Through the above technical solution, the guide plate will divert the falling debris to the bottom of the sewage pipe, where it will be discharged by the second auger shaft, and the debris will not affect the rotation of the first connecting rod.

[0020] The beneficial effects of this utility model are as follows:

[0021] 1. This utility model designs a discharge mechanism that uses a drive motor to power the first and second auger shafts and the scraper. The scraper pushes impurities on the filter plate into the sewage pipe, where they are discharged by the first and second auger shafts. This discharge mechanism can separate the flow of water from the discharge of impurities, preventing impurities in the flow of water from affecting the discharge process.

[0022] 2. This utility model designs a first bevel tooth, a second bevel tooth, and a third bevel tooth that mesh with each other. When the power is transmitted from the first bevel tooth by the drive motor, the force can be distributed to different transmission paths through meshing with the second and third bevel teeth, avoiding excessive local stress, thereby improving the load-bearing capacity of the entire transmission system and the synchronization of the entire transmission system.

[0028] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0029] Please see Figure 1 - Figure 3 A bridge rapid drainage device includes a drainage pipe 1, an installation pipe 2 fixedly connected to the top of the drainage pipe 1, a protective cover 3 installed on the top of the installation pipe 2, a plurality of filter holes 4 opened on the top of the protective cover 3, a funnel-shaped filter pipe 5 installed inside the drainage pipe 1 near the top, a filter plate 6 installed inside the funnel-shaped filter pipe 5, and a sewage pipe 7 fixedly connected to the bottom of the funnel-shaped filter pipe 5.

[0030] like Figure 4As shown, a discharge mechanism 8 is installed inside the drain pipe 1 near the sewage pipe 7. The discharge mechanism 8 includes a mounting block 801 installed on the outer wall of the drain pipe 1. A drive motor 802 is installed inside the mounting block 801. A first conical tooth 803 is installed at the output end of the drive motor 802. A second conical tooth 804 is rotatably connected to the outer wall of the first conical tooth 803. A first connecting rod 805 is installed on the top of the second conical tooth 804. A hole corresponding to the first connecting rod 805 is opened on the top of the guide plate 9. The guide plate 9 will guide the falling debris to the bottom of the sewage pipe 7, where it will be discharged by the second auger shaft 811. This will not affect the rotation of the first connecting rod 805. A first auger shaft 806 is fixedly connected to the top of the first connecting rod 805, and a rotating rod 807 is fixedly connected to the top of the first auger shaft 806. Two scrapers 808 are installed on the outer wall of the rotating rod 807. The top of the filter plate 6 has through holes corresponding to the scrapers 808. During filtration, impurities easily accumulate on the filter plate 6. The through holes allow the scrapers 808 to act directly on the surface of the filter plate 6. When the scrapers 808 move, they can push away the impurities accumulated on the filter plate 6 through the through holes, preventing the impurities from forming a thick accumulation layer on the filter plate 6 and causing blockage. To ensure the continuous and efficient operation of the filtration process, a third conical tooth 809 is rotatably connected to the outer wall of the second conical tooth 804. The first conical tooth 803 meshes with the second conical tooth 804 and the third conical tooth 809. The meshing of multiple conical teeth allows for a more even distribution of force in the transmission system. When power is transmitted from the first conical tooth 803, the force is dispersed to different transmission paths through meshing with the second conical tooth 804 and the third conical tooth 809, avoiding excessive local stress and thus improving the load-bearing capacity of the entire transmission system. A second connecting rod 810 is fixedly connected to the other side of the third conical tooth 809. The other end of the second connecting rod 810 is fixedly connected to the second auger shaft 811. Both the first auger shaft 806 and the second auger shaft 811 are made of stainless steel. Stainless steel has good chemical corrosion resistance, which prevents the auger shaft from being damaged by corrosion and thus extends its service life. The outer walls of the first auger shaft 806 and the second auger shaft 811 are attached to the inner wall of the sewage pipe 7. During the process of the auger shaft rotating to discharge debris, the debris can be effectively pushed forward, reducing the residue of debris in the sewage pipe 7. This can ensure that as much debris as possible is transported to the designated position, improving the efficiency of debris discharge. A guide plate 9 is installed inside the sewage pipe 7.

[0031] like Figure 4As shown, during drainage, larger impurities in the water are blocked by the protective cover 3, while smaller impurities enter the device with the water flow and are blocked by the funnel-shaped filter tube 5 and filter plate 6. The filtered water is drained through the drain hole. After a certain amount of impurities accumulate on the filter plate 6, the drive motor 802 starts to operate, driving the first conical tooth 803 to rotate. The rotation of the first conical tooth 803 drives the second conical tooth 804 to move forward. The rotation of the first auger shaft 806 causes the first auger shaft 806 to rotate, which in turn causes the two scrapers 808 to rotate via the rotating rod 807. The two scrapers 808 discharge the debris on the filter plate 6 through the through holes of the filter plate 6. The debris that falls off is discharged into the drain pipe 7 through the first auger shaft 806. The rotation of the second conical tooth 804 also causes the third conical tooth 809 to rotate, which in turn causes the second auger shaft 811 to rotate, discharging the debris from inside the drain pipe 7.

[0032] When this utility model is in use, during drainage, larger impurities in the flowing water are blocked by the protective cover 3, while smaller impurities enter the interior of the device with the flowing water and are blocked by the funnel-shaped filter pipe 5 and the filter plate 6. The filtered water is drained through the drain hole. After a certain amount of impurities accumulate on the filter plate 6, the drive motor 802 starts to run, driving the first conical tooth 803 and the scraper 808 to rotate. When the scraper 808 moves, it removes the impurities accumulated on the filter plate 6 through the through hole. Impurities that fall onto the first auger shaft 806 are transported to the inside of the drain pipe 7 with the rotation of the first auger shaft 806 and discharged by the second auger shaft 811.

[0033] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
