Description

Technical Field

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

[0002] A tunnel is a traffic passage that can be used as a pedestrian or vehicle passage. Generally, when a tunnel is used, a drainage outlet is set up in the tunnel, and a filter plate is set on the drainage outlet in the tunnel to filter impurities in the water passing through the drainage outlet.

[0003] The existing tunnel drainage device uses a filter plate to filter larger stones to prevent the stones from clogging the drainage pipe. However, the tunnel drainage device is unable to filter smaller sediment. After long-term use, the sediment continues to settle and accumulate in the drainage pipe, which is prone to blockage, thus affecting the normal drainage of the tunnel. Utility Model Content

[0027] A tunnel is a traffic passage that can be used as a pedestrian or vehicle passage. Generally, when a tunnel is used, a drainage outlet is set up in the tunnel, and a filter plate is set on the drainage outlet in the tunnel to filter impurities in the water passing through the drainage outlet.

[0028] In the related technology, it is not possible to filter smaller silt. After long-term use, the silt continues to settle and accumulate in the drainage pipe, which is prone to blockage, thereby affecting the normal drainage of the tunnel.

[0029] In order to solve the problems in the related technology to a certain extent, the embodiment of the present application provides a tunnel drainage device. When it is necessary to clear the blockage caused by silt accumulation, the water flow will impact the push plate 24, so that the push plate 24 is affected by the impact of the water flow and pushes the conveyor belt 23 to rotate through the rotating shaft 22. The rotating conveyor belt 23 drives the push plate 24 to feed back the thrust of the water flow to the water flow, thereby accelerating the flow rate of the water flow and avoiding the situation where the silt carried in the water flow is weakened due to the weakening of the flow rate, resulting in the silt settling and accumulating in the drainage pipe 11. At the same time, the push plate 24 drives the scraper 25 to scrape away the silt accumulated in the drainage pipe 11 as it rotates in circles.

[0030] The present application is described below with reference to specific embodiments and with reference to the accompanying drawings:

[0031] Combine Figure 1-Figure 3 An embodiment of the present application provides a tunnel drainage device, including a device body 1; the device body 1 includes: a filter plate 12 is provided on the top of the drainage pipe 11, and passes through the top of the drainage pipe 11; an anti-blocking component 2 is provided inside the drainage pipe 11, and the anti-blocking component 2 includes: a support rod 21 symmetrical to the inside of the drainage pipe 11; a rotating shaft 22 is provided on the outside of the support rod 21; a conveyor belt 23 is provided on the outside of the rotating shaft 22; a push plate 24 is symmetrical to the outside of the conveyor belt 23; and a scraper 25 is provided at the bottom of the push plate 24.

[0032] During use, accumulated water flows in from the drain outlet at the top of the drainage pipe 11, and the stones carried in the water flow are filtered out through the filter plate 12. Then the water flow flows in the drainage pipe 11 and impacts the push plate 24, so that the push plate 24 is affected by the impact of the water flow and pushes the conveyor belt 23 to rotate through the rotating shaft 22. The rotating conveyor belt 23 feeds back the thrust of the water flow to the water flow through the push plate 24, thereby accelerating the flow rate of the water flow and avoiding the sediment carried in the water flow from being deposited and accumulated in the drainage pipe 11 due to the weakening of the flow rate. At the same time, the push plate 24 drives the scraper 25 to scrape away the sediment accumulated in the drainage pipe 11 as it rotates in circles, thereby increasing the anti-blocking property of the tunnel drainage device and improving the drainage effect of the tunnel drainage device.

[0033] In some embodiments, a slot 251 is provided on the top of the scraper 25 to match the push plate 24 , so that the push plate 24 and the scraper 25 are snap-connected, making it easy to disassemble, assemble and repair the scraper 25 .

[0034] In some embodiments, a through hole 252 is provided on the push plate 24 and the slot 251, and a fixing bolt 253 is provided on the scraper 25, which passes through the push plate 24 and the slot 251. The push plate 24 and the scraper 25 are threadedly fixed by the fixing bolt 253, thereby increasing the stability of the scraper 25 installed on the push plate 24.

[0035] In some embodiments, sliders 26 are provided at both ends of the support rod 21 , and a sliding groove 261 that cooperates with the sliders 26 is provided on the inner wall of the drainage pipe 11 , so as to facilitate the disassembly and assembly of the entire anti-blocking assembly 2 .

[0036] In some embodiments, a thread 27 is provided on the outer side of the support rod 21, and a threaded sleeve 271 is provided on the outer side of the support rod 21 to match the thread 27. After the sliders at both ends of the support rod 21 are slid into the bottom of the slide groove 261 for installation, the threaded sleeve 271 is rotated, and the rotating threaded sleeve 271 moves toward the inner wall of the drainage pipe 11 and squeezes, thereby squeezing and fixing the support rod 21.

[0037] In some embodiments, an extrusion plate 28 is provided on one side of the threaded sleeve 271 and is sleeved on the outside of the support rod 21, increasing the area of ​​the threaded sleeve 271 squeezing the inner wall of the drainage pipe 11 and improving the stability of squeezing and fixing the support rod 21.

[0038] In some embodiments, an anti-slip pad 281 is provided on the side of the extrusion plate 28 close to the inner wall of the drainage pipe 11 , thereby increasing the anti-slip property of the extrusion plate 28 when squeezing the inner wall of the drainage pipe 11 .

[0039] In some embodiments, connecting plates 13 are provided on both sides of the filter plate 12 and are fixed to the drainage pipe 11 by bolts, so as to facilitate the disassembly and assembly of the filter plate 12 .
