Detailed implementation mode

[0022] Next, the technical solutions in the embodiments of this patent will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of this patent. Obviously, the described embodiments are only a part of the embodiments of this patent, rather than all the embodiments. Based on the embodiments in this patent, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this patent.

[0023] Please refer to Figures 1-4 , this patent provides a technical solution: a tunnel water accumulation suction device, including a self-priming pump 1. The self-priming pump 1 is a ZX series horizontal self-priming pump. The self-priming pump 1 is powered on for operation. A water inlet 2 and a water outlet 3 are respectively arranged on the self-priming pump 1. A second hose 5 is installed in the water outlet 3, and a filtering structure 4 is installed in the water inlet 2. The filtering structure 4 includes a filter plate 401, a servo motor 402, a scraper 403, a first hose 404, and a metal pipe 405;

[0024] The first hose 404 is installed in the water inlet 2, the metal pipe 405 is installed on the first hose 404, the filter plate 401 is installed on the metal pipe 405. The filter plate 401 is made of stainless steel with holes on its surface. The servo motor 402 is installed on the filter plate 401. The output shaft of the servo motor 402 passes through the central hole on the filter plate 401, and the scraper 403 is installed on the output shaft of the servo motor 402. The scraper 403 contacts the filter plate 401;

[0025] An outer shell 8 is installed on the filter plate 401. The servo motor 402 is installed in the outer shell 8. The outer shell 8 protects the servo motor 402. A battery 9 is installed in the outer shell 8. The battery 9, the remote control switch installed inside the outer shell 8, and the servo motor 402 are electrically connected and controlled by an external remote control switch. The battery 9 can be charged by an external wire. A round groove 10 is opened on the outer shell 8, and a sealed bearing 11 is installed in the round groove 10. The output shaft of the servo motor 402 is installed in the inner ring of the sealed bearing 11.

[0026] The outer surface of the metal pipe 405 is processed with external threads, and an internal thread sleeve 6 is sleeved on the external threads. The filter plate 401 is placed inside the internal thread sleeve 6. The internal thread sleeve 6 presses the filter plate 401 against the metal pipe 405. A rubber ring 7 is glued to the filter plate 401. The rubber ring 7 is made of fluororubber material and has characteristics such as corrosion resistance. The inner and outer diameters of the rubber ring 7 are the same as the inner and outer diameters of the metal pipe 405. The rubber ring 7 contacts the metal pipe 405. During installation, the rubber ring 7 is fixed to the filter plate 401 by gluing. The filter plate 401 is placed into the internal thread sleeve 6, and the internal thread sleeve 6 is screwed onto the external threads outside the metal pipe 405, so that the rubber ring 7 on the filter plate 401 is pressed against the metal pipe 405 for fixation. Conversely, it can be disassembled, replaced or repaired. When in use, the metal pipe 405 on the first hose 404 is thrown into the sump of tunnel construction. At this time, the self-priming pump 1 is started. Then the self-priming pump 1 pumps out the accumulated water through the metal pipe 405 on the first hose 404 and discharges it outside the tunnel through the second hose 5. During the process of pumping the accumulated water, the filter plate 401 can filter the sediment in the accumulated water. In order to prevent the filter plate 401 from being blocked, an external remote control is started, then the remote control switch is turned on, and the storage battery 9 supplies power to the servo motor 402. The output shaft of the servo motor 402 rotates on the housing 8 through a sealed bearing 11 and also rotates on the central hole of the filter plate 401. Then the output shaft of the servo motor 402 drives the scraper 403 to rotate, which can scrape the sediment attached to the surface of the filter plate 401 and prevent the filter plate 401 from being blocked.

[0027] A fixing structure 12 is installed outside the internal thread sleeve 6. If it is not stable, a fixing structure 12 can be installed on the other side of the internal thread pipe 6. The fixing structure 12 includes a U-shaped block 13, a telescopic plate 14 and a plug board 15;

[0028] The U-shaped block 13 is installed on the internal thread sleeve 6. One end of the telescopic plate 14 is rotatably installed in the U-shaped block 13 through a pin shaft, and the plug board 15 is rotatably installed on the other end of the telescopic plate 14 through a pin shaft. The telescopic plate 14 includes a sleeve plate 16, a convex plate 17 and a fixing screw 18;

[0029] The template 16 is rotatably installed in the U-shaped block 13 through a pin shaft, and the convex plate 17 is rotatably installed in the insertion plate 15 through a pin shaft. The convex plate 17 is inserted into the template 16. Threaded grooves are provided on the template 16, and the fixing screw 18 is sleeved in the threaded grooves. The fixing screw 18 abuts against the convex plate 17. When the metal pipe 405 on the first hose 404 is thrown into the sump of tunnel construction, according to the position where the insertion plate 15 is inserted into the soil, the convex plate 17 is adjusted to expand and contract along the template 16. After adjustment, the fixing screw 18 is screwed to limit the convex plate 17 in the template 16. Then, the template 16 rotates in the U-shaped block 13 through the pin shaft, and the convex plate 17 rotates and adjusts in the insertion plate 15 through the pin shaft, so that the insertion plate 15 is inserted into the soil in the tunnel construction sump, and the metal pipe 405 sinks into the sump for fixation, preventing the metal pipe 405 from floating out of the sump water surface due to the buoyancy of the water.

[0030] When using this tunnel sump suction device, during installation, first, the rubber ring 7 is fixed on the filter plate 401 by gluing. The filter plate 401 is placed into the internal thread sleeve 6, and the internal thread sleeve 6 is screwed onto the external thread outside the metal pipe 405, so that the rubber ring 7 on the filter plate 401 abuts against the metal pipe 405 for fixation. Conversely, it can be disassembled, replaced, or repaired. During use, the metal pipe 405 on the first hose 404 is thrown into the sump of tunnel construction. When the metal pipe 405 on the first hose 404 is thrown into the sump of tunnel construction, according to the position where the insertion plate 15 is inserted into the soil, the convex plate 17 is adjusted to expand and contract along the template 16. After adjustment, the fixing screw 18 is screwed to limit the convex plate 17 in the template 16. Then, the template 16 rotates in the U-shaped block 13 through the pin shaft, and the convex plate 17 rotates and adjusts in the insertion plate 15 through the pin shaft, so that the insertion plate 15 is inserted into the soil in the tunnel construction sump, and the metal pipe 405 sinks into the sump for fixation, preventing the metal pipe 405 from floating out of the sump water surface due to the buoyancy of the water. At this time, the self-priming pump 1 is started, and the self-priming pump 1 pumps out the sump water through the metal pipe 405 on the first hose 404 and discharges it outside the tunnel through the second hose 5. During the process of pumping the sump water, the filter plate 401 can filter the sediment in the sump water. In order to prevent the filter plate 401 from being blocked, the external remote controller is started, then the remote control switch is turned on, and the storage battery 9 supplies power to the servo motor 402. The output shaft of the servo motor 402 rotates on the housing 8 through the sealed bearing 11 and also rotates on the central hole on the filter plate 401. Then, the output shaft of the servo motor 402 drives the scraper 403 to rotate, which can scrape the sediment attached to the surface of the filter plate 401 and prevent the filter plate 401 from being blocked.
