Technical Field

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

[0002] Expressway, referred to as highway, refers to a road specially designed for high-speed driving of automobiles. Expressways have different regulations in different countries, regions, eras and scientific research and academic fields. With the continuous development of social economy, the number of highways in my country is increasing. The construction of highways is inseparable from the construction of bridges, and the drainage system of bridges is also an important part of bridges. At present, bridge deck waterproofing has made great progress, and there is a lot of technical accumulation and it is becoming more and more mature.

[0003] After searching, the Chinese patent "A drainage structure for highway bridges" authorization announcement number "CN214939246U" shows that the drainage structure for highway bridges can better drain water when in use through the cooperation between drainage ditches, drainage hoses, filter boxes, sliding rods and filter nets, and can filter out debris in the accumulated water, thereby avoiding the debris from being discharged into the water area along with the accumulated water, affecting the ecological environment, and thus greatly improving the practicality of the drainage structure;

[0004] Although the above application filters the impurities in the accumulated water and separates the impurities from the water, the separated impurities will remain on the filter. The remaining impurities will affect the filtering performance of the filter and easily cause the filter to be blocked, affecting the normal operation of the device.

[0005] Therefore, a drainage structure for a highway bridge is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] When implementing: Figure 1-4 As shown, a drainage structure of a highway bridge comprises:

[0026] A bridge body 100 and a drainage ditch 200, wherein the drainage ditch 200 is provided on the bridge body 100;

[0027] The drainage mechanism 300 includes a treatment box 310 disposed at the bottom end of the bridge body 100, and a placement frame 311 is provided on both sides of the treatment box 310. A motor 312 is fixedly connected to the bottom end of the bridge body 100, and a reciprocating screw 313 is fixedly connected to the output shaft of the motor 312. A slider 314 is provided on the reciprocating screw 313, and a movable plate 315 is fixedly connected to the surface of the slider 314. A scraper 316 is provided at the bottom end of the movable plate 315. A filter plate 317 is provided in the treatment box 310, and a collecting pipe 318 is provided at the bottom end of the treatment box 310, and a drainage pipe 319 is provided on the surface of the collecting pipe 318.

[0028] like Figure 2 , Figure 3 and Figure 4 As shown, a plurality of springs 3151 are provided between the moving plate 315 and the scraper 316, and the connection between the processing box 310 and the placement frame 311 is arc-shaped. The arc-shaped connection can separate the placement frame 311 and the processing box 310, and the springs 3151 cooperate with the arc-shaped connection to improve the effect of impurity separation and prevent sliding backflow.

[0029] like Figure 3 As shown, the bottom end of the treatment box 310 is fixedly connected with a filter cartridge 3182, and the upper end of the filter cartridge 3182 is funnel-shaped. The water can be filtered again, and the upper end is funnel-shaped to gather the water.

[0030] The bottom end of the gathering pipe 318 is threadedly connected with a sealing cap 3181, and the sealing cap 3181 is in close contact with the filter cartridge 3182. By rotating the sealing cap 3181, impurities in the filter cartridge 3182 can be taken out, making maintenance more convenient.

[0031] like Figure 1 , Figure 2 and Figure 3 As shown, a placement plate 3111 is provided in the placement frame 311, and a hose 3112 is provided between the placement plate 3111 and the processing box 310. The placement plate 3111 can intercept impurities to prevent the impurities from moving into the placement frame 311, making it easier to clean up later, and can also separate water and impurities to reduce the water content in the impurities, making it easier to clean up later.

[0032] The processing box 310 and the placement frame 311 are both fixedly connected with a positioning frame 3113, and the corresponding positioning frame 3113 is in close contact with the filter plate 317 and the placement plate 3111. The positioning frame 3113 can provide a positioning function for the installation of the filter plate 317 and the placement plate 3111, and the filter plate 317 and the placement plate 3111 are also relatively simple to disassemble during maintenance.

[0033] like Figure 1As shown, the bottom end of the bridge body 100 is fixedly connected with a limit rod, and the movable plate 315 is slidably connected to the limit rod. The limit rod can limit the movable plate 315, so that the movable plate 315 can move stably in the horizontal direction without deviation, thereby ensuring the normal operation of the device.

[0034] Working principle: During normal drainage, water on the bridge body 100 will be discharged into the treatment box 310 through the drainage trough 200, and the drainage will pass through the filter plate 317 and enter the collecting pipe 318, and will be discharged or collected for reuse through the drainage pipe 319. When the surface of the filter plate 317 needs maintenance, the motor 312 is started, and the reciprocating screw 313 rotates, so that the slider 314 drives the moving plate 315 to reciprocate along a predetermined route, thereby driving the scraper 316 to move and scrape the top of the filter plate 317. The scraper 316 will gather and move the impurities. After crossing the arc connection, the impurities will automatically enter the corresponding placement frame 311. During the crossing process, the spring 3151 automatically adjusts the distance between the moving plate 315 and the scraper 316. When the impurity mixture enters the placement frame 311, it will stay on the placement plate 3111, and the water therein will pass through the placement plate 3111 and enter the bottom end of the placement frame 311, and enter the collecting pipe 318 through the hose 3112.

[0035] It should be noted that the bridge body 100, drainage trough 200, motor 312, reciprocating screw 313, slider 314, etc. in the above description are all relatively mature devices in existing technology applications. The specific models can be selected according to actual needs. At the same time, the motor 312 can be powered by a built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0036] Note: The reciprocating screw is in the form of two thread grooves with the same pitch and opposite rotation direction, and the two ends are connected by a transition curve. Through the rotation of the reciprocating screw, the side of the spiral groove pushes the slider placed in the spiral groove to perform axial reciprocating motion.

[0037] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
