[0026] like Figure 2 As shown, two fixing blocks 22 are fixedly connected to the upper left and right sides of the inner surface of the water reservoir 1. The two fixing blocks 22 at the same end are connected to a roller 23 at their ends that are close to each other and rotate together. Two sliding rods 25 are fixedly connected to the rear side wall of the inner surface of the water reservoir 1.

[0027] The two sliding rods 25 are both slidably connected to the support plate 24 .

[0029] The lower end of the filter frame 4 is fixedly connected to the upper end of the rotating shaft 1 32 and the upper end of the connecting block 2 38;

[0030] During the actual use of the device, water in the pedestrian crosswalk and intercepting ditch in the tunnel is filtered by the filter frame 4 and flows into the water reservoir 1. When it is necessary to clean the debris in the filter frame 4, the winch 21 is started, and the winch 21 pulls the support plate 24 up through the pull rope. The support plate 24 drives the flip assembly 3 and the filter frame 4 to rise to the upper end of the water reservoir 1 under the guidance of the slide bar 25, and then the motor 39 drives the rotating plate 35 to rotate. When the rotating plate 35 rotates, the end of the rotating plate 35 away from the fixed block three 34 drives the connecting rod 36 to rise, thereby driving the connecting block two 38 to move upward, and then the side of the filter frame 4 fixedly connected to the connecting block one 33 rotates around the rotating shaft one 32, and the end of the filter frame 4 fixedly connected to the connecting block two 38 moves upward, thereby flipping the filter frame 4 and pouring out the debris in the filter frame 4. The staff can clean the inside of the filter frame 4.

[0032] like Figure 5 As shown, the filter portion 54 includes a filter cartridge 541 fixedly connected to the water inlet pipe 53. A fixing ring 542 is fixedly connected to the inner surface of the filter cartridge 541. A third rotating shaft 543 is rotatably connected to the middle portion of the fixing ring 542 at one end away from the water inlet pipe 53. A runner 544 is fixedly connected to the middle portion of the outer surface of the third rotating shaft 543. A scraper 545 is fixedly connected to the end of the third rotating shaft 543 away from the fixing ring 542.

[0033] The outlet pipe 52 is specifically a DN300 pipe. DN300 pipe, i.e., a pipe with a diameter of 300 mm, is one of the commonly used pipes in the industrial and construction fields. It is widely used in many fields such as oil and natural gas transportation, construction engineering, and water treatment. Due to its large diameter and thick wall design, DN300 pipe has a high pressure bearing capacity and impact resistance. It is usually treated with anti-corrosion, which can effectively resist the erosion of chemicals and corrosive media, thereby extending its service life.

[0034] During the actual use of the device, the filter frame 4 cannot filter out all impurities, and some impurities will flow into the water reservoir 1. When the water in the water reservoir 1 is extracted and discharged by the water pump 51, the water will flow into the filter cartridge 541. The impact force of the water drives the impeller 544 to rotate, and the impeller 544 drives the rotating shaft 543 to rotate, and the rotating shaft 543 drives the scraper 545 to rotate, so that the outer surface of the filter cartridge 541 is cleaned by the scraper 545 to prevent impurities from clogging the filter cartridge 541. The rotation of the impurities 544 can also prevent impurities from entering the filter cartridge 541 and clogging the water inlet pipe 53. The water pump 51 then discharges the water through the outlet pipe 52. The filter frame 4 and the pumping assembly 5 can filter the water multiple times to prevent impurities from clogging the water inlet pipe 53.

[0035] It should be noted that the specific installation methods, circuit connection methods and control methods of the winch 21, motor 39 and water pump 51 used in the present invention are all conventional designs and will not be elaborated in detail in the present invention.

[0036] The working principle of the utility model is: the water discharged by the multiple walkways and intercepting cross ditches in the tunnel flows into the water storage pool 1, firstly, the water flows into the filter frame 4, the sundries in the water are left in the filter frame 4 through the filtration of the filter frame 4, the water flows into the water storage pool 1 through the filter holes of the filter frame 4, then the water in the water storage pool 1 is pumped out through the water pump 51, the water flows to the filter cylinder 541, the impact force of the water drives the rotating wheel 544 to rotate, the rotating wheel 544 drives the rotating shaft three 543 to rotate, the rotating shaft three 543 drives the scraper 545 to rotate, thereby the outer surface of the filter cylinder 541 is cleaned through the scraper 545, the sundries are prevented from blocking the filter cylinder 541, the rotating wheel 544 rotating can also prevent the sundries from entering the filter cylinder 541 to block the water inlet pipe 53, the water pump 51 discharges the water through the water outlet pipe 52, when the sundries in the filter frame 4 need to be cleaned, the winch 21 is started, the winch 21 drives the support plate 24 to ascend through the pull rope, the support plate 24 drives the turnover assembly 3 and the filter frame 4 to ascend to the upper end of the water storage pool 1 under the guidance of the slide rod 25, then the rotating plate 35 is driven to rotate through the motor 39, when the rotating plate 35 rotates, the end of the rotating plate 35 away from the fixed block three 34 drives the connecting rod 36 to ascend, thereby the connecting block two 38 is driven to move upwards, then the side of the filter frame 4 fixedly connected with the connecting block one 33 rotates around the rotating shaft one 32, the end of the filter frame 4 fixedly connected with the connecting block two 38 moves upwards, thereby the filter frame 4 is turned over, the sundries in the filter frame 4 are poured out, the staff can clean the inside of the filter frame 4.
