Description

Technical Field

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

[0002] The road and bridge drainage system is a key component in ensuring the safety of the project. Through facilities such as rainwater inlets, drainage ditches, pipes, and sedimentation tanks, it can quickly collect, guide, and discharge surface water and infiltration water to prevent water accumulation on the road surface, structural erosion, and freeze-thaw damage. A scientifically designed drainage scheme can effectively protect the stability of the roadbed, extend the service life of the bridge, and reduce environmental pollution through rainwater purification treatment, thus ensuring driving safety and project durability.

[0003] A search revealed a Chinese patent with publication number CN221480547U that discloses a drainage device for road and bridge engineering. The device includes a main frame, a connecting shaft fixedly connected to the inner side of the main frame, an anti-blocking frame movably connected to the upper side of the main frame, and one end of the anti-blocking frame movably connected to the main frame via the connecting shaft. A water guiding ring plate is fixedly connected inside the main frame, a debris blocking mechanism is movably connected to the lower side of the water guiding ring plate, and a support frame is fixedly connected to the lower side of the main frame.

[0004] While the above solutions can drain water, there is still room for improvement in terms of filtration and sewage discharge. Currently, the sewage discharge process relies on manual operation, which not only increases the workload and maintenance costs of maintenance personnel in areas with continuous heavy rainfall, but may also lead to a decrease in drainage efficiency due to untimely response, thus posing a certain risk of water accumulation. Therefore, we provide a drainage device for road and bridge engineering to solve the above problems. Utility Model Content

[0011] Compared with the prior art, this utility model provides a drainage device for road and bridge engineering, which has the following beneficial effects:

[0012] 1. This road and bridge engineering drainage device, through the coordinated arrangement of components in the treatment mechanism, enables multiple filtrations of rainwater flowing into the treatment pool and the automated cleaning and discharge of impurities in the rainwater, significantly improving the drainage efficiency of the device.

[0019] 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.

[0020] Please see Figure 1-5This utility model provides a drainage device for road and bridge engineering, including a treatment pool 1. The treatment pool 1 is equipped with a drain pipe 8 and a sewage pipe 9. Two side plates 6 are symmetrically fixedly connected inside the treatment pool 1. A first filter plate 208 is installed between the two side plates 6. A second filter plate 209 is installed on the side plate 6 below the first filter plate 208. A sewage outlet 7 is opened on the side plate 6 above the first filter plate 208. The surfaces of the first filter plate 208 and the second filter plate 209 are coated with a wear-resistant and corrosion-resistant coating to prevent corrosion damage caused by rainwater. Through the arrangement of the first filter plate 208 and the second filter plate 209, the rainwater inside the treatment pool 1 can be filtered multiple times, so that the impurities in the rainwater are separated from the rainwater more thoroughly.

[0021] The treatment tank 1 is equipped with a treatment mechanism 2 for filtering and discharging sewage. The treatment mechanism 2 includes an active rotating roller 201, which is located above the first filter plate 208. Both ends of the active rotating roller 201 are rotatably connected to the side plate 6. The outer surface of the active rotating roller 201 is provided with a reciprocating groove 202. A driven reciprocating slip ring 204 is slidably sleeved on the active rotating roller 201. A limit frame 203 is rotatably connected to the driven reciprocating slip ring 204. The limit frame 203 passes through the driven reciprocating slip ring 204 and is slidably connected to the reciprocating groove 202. A driven connecting rod 205 is fixedly connected to the lower end of the driven reciprocating slip ring 204. A reciprocating cleaning plate 207 is fixedly connected to the lower end of the driven connecting rod 205. The reciprocating cleaning plate 207 is close to the first filter plate 208.

[0022] A drive motor is fixedly installed inside the treatment tank 1. The output end of the drive motor is fixedly connected to the active rotating roller 201. By starting the drive motor, the active rotating roller 201 can be effectively driven to rotate. Through the coordinated action of the reciprocating slide chute 202 and the limiting frame 203, when the active rotating roller 201 is driven to rotate, the driven reciprocating slip ring 204 can be driven to reciprocate and slide synchronously on the surface of the active rotating roller 201. By driving the driven reciprocating slip ring 204 to reciprocate, the driven connecting rod 205 can be driven to reciprocate and slide simultaneously within the inner wall of the treatment tank 1. By driving the reciprocating cleaning plate 207 to reciprocate, the impurities filtered on the surface of the first filter plate 208 can be effectively scraped and cleaned to both sides of the treatment tank 1 for further filtration by the second filter plate 209.

[0023] A drive sprocket 210 is rotatably connected to the inner wall of the treatment tank 1. A drive chain 211 is driven to the outer surface of the drive sprocket 210. A rotating motor is fixedly installed inside the treatment tank 1. The output end of the rotating motor is fixedly connected to the drive sprocket 210. Driven sprockets 212 are driven to both ends of the drive chain 211. The outer surfaces of the two driven sprockets 212 are fixedly connected to two auger push rollers 206. The auger push rollers 206 are located between the side plate 6 and the inner wall of the treatment tank 1, and one end of the auger push rollers 206 is aligned with the opening of the sewage pipe 9. By driving the drive chain 211, the driven sprockets 212 can be driven to rotate synchronously. By driving the driven sprockets 212 to rotate, the auger push rollers 206 can be effectively driven to rotate. When the auger push rollers 206 rotate, they can scrape the surface of the second filter plate 209 and push the filtered impurities on both sides of the treatment tank 1 to be discharged outward.

[0024] The treatment tank 1 is equipped with a triggering mechanism 3 for monitoring the water level. The triggering mechanism 3 includes a limiting slide cylinder 301, the upper end of which is fixedly connected to the first filter plate 208. A pressure sensor body 302 is fixedly connected to the inner wall of the upper end of the limiting slide cylinder 301. A driven slide rod 303 is slidably connected to the inner wall of the limiting slide cylinder 301. A float plate 304 is fixedly connected to the lower end of the driven slide rod 303. The outer surface of the float plate 304 is coated with an anti-corrosion and anti-adhesion coating. The first filter plate 208 effectively supports and fixes the pressure sensor body 302. A controller for receiving commands from the pressure sensor body 302 is fixedly installed on the inner wall of the limiting slide cylinder 301. This controller is existing technology and is not shown in the figure. Through the controller, the device can effectively receive signal commands sent by the pressure sensor body 302 and immediately start the drive motor, rotary motor, and solenoid valve body 5 upon receiving the signal.

[0025] The top surface of the treatment pool 1 is hinged with a drain plate 4 via a pin. The drain plate 4 effectively allows rainwater from the road and bridge surface to flow into the treatment pool 1 for centralized collection and treatment. By opening the solenoid valve body 5, impurities and rainwater in the treatment pool 1 can be effectively discharged outward.

[0026] Electromagnetic valve bodies 5 are installed at the openings of the sewage pipe 9 and the drain pipe 8. The drain pipe 8 is located below the first filter plate 208, and the sewage pipe 9 is located on both sides of the drain pipe 8. The electromagnetic valve body 5, the pressure sensor body 302, and the controller mentioned in this application, as well as the drive motor, the rotary motor, and the pump body mentioned, are all common electrical equipment and electronic components in the prior art, and their models and internal structures will not be described in detail.

[0027] The treatment pool 1 is equipped with a power control box, which is electrically connected to the municipal power supply and can supply power to the electrical equipment in this application.

[0028] Working principle:

[0029] When the water level in treatment tank 1 rises, the float plate 304 will float and move upwards synchronously. The upward movement of the float plate 304 causes the driven slide rod 303 to slide upwards within the limiting slide cylinder 301. If the driven slide rod 303 slides upwards and contacts the pressure sensor body 302, the pressure sensor body 302 will sense the pressure and immediately send a signal to the controller within the limiting slide cylinder 301, indicating that the water level inside treatment tank 1 has exceeded the threshold. The controller will then trigger the electrical equipment start command in this device, effectively activating the electrical equipment within treatment tank 1 and the treatment tank itself. When the solenoid valve body 5 on the drain pipe and the discharge pipe on the surface of the treatment tank 1 is opened, the drive motor inside the treatment tank 1 will drive the active roller 201 to rotate. During the rotation of the active roller 201, in conjunction with the synergistic effect of the reciprocating slide groove 202 and the limiting frame 203, it can effectively drive the driven reciprocating slip ring 204 to slide back and forth on the surface of the active roller 201. The reciprocating sliding of the driven reciprocating slip ring 204 drives the reciprocating cleaning plate 207 on one end of the driven connecting rod 205 to move back and forth to clean the impurities filtered on the surface of the first filter plate 208. The impurities are scraped and cleaned through the drain outlet 7 to both sides of the treatment tank 1. Then, the second filter plate 209 filters the impurities on both sides again. At the same time, the rotating motor inside the treatment tank 1 drives the drive sprocket 210 to rotate. The rotation of the drive sprocket 210 drives the transmission chain 211 through the meshing force. The transmission chain 211 drives the auger push roller 206 on the surface of the driven sprocket 212 to rotate. The rotation of the auger push roller 206 effectively scrapes the surface of the second filter plate 209 while pushing the filtered impurities evenly. The device moves towards the drain pipe 9 on the surface of the treatment tank 1. Since the solenoid valve body 5 on the drain pipe 9 and the drain pipe 8 on the surface of the treatment tank 1 is in the open state, the rainwater and impurities in the treatment tank 1 can be effectively separated and discharged. This optimization significantly improves the drainage efficiency of the device. Compared with the traditional equipment that relies on manual cleaning, which leads to increased maintenance costs and delayed cleaning, this device effectively avoids water accumulation caused by untimely cleaning through an automated operation and maintenance mechanism, greatly reducing the labor intensity of workers and operation and maintenance costs.
