Description

Technical Field

[0001] The invention belongs to the technical field of drainage devices, and in particular relates to a tunnel drainage device for highway construction. Background Art

[0002] As an important part of modern transportation infrastructure, the construction of expressways is not only related to economic development, but also involves environmental protection, traffic safety and other aspects. In complex terrain conditions such as mountainous areas, tunnels have become an indispensable part of expressway design. During the construction of tunnels, a large amount of water will accumulate inside the tunnels, which needs to be discharged in time through drainage devices.

[0003] The existing tunnel drainage device can divert the pumped sewage through the diverter, and part of the sewage is diverted to the mixing mechanism through the diverter through the water pipe. While achieving moderate mixing of the sewage, it can also buffer the sewage pumped by high-pressure pumping, thereby indirectly avoiding the high-intensity pumping of the mud pump that may affect its service life and appropriately reducing the operation and maintenance frequency of the drainage device.

[0004] Although the existing tunnel drainage system can effectively buffer the sewage pumped by high-pressure pumps, the stirring mechanism is in direct contact with the tunnel water containing a large number of solid particles. With the continuous suction action of the pump, these solid particles are sucked into the stirring mechanism in large quantities, which not only interferes with the normal operation of the stirring mechanism, but may also enter the pump body and damage the internal structure, thereby shortening the service life of the entire device.

[0005] Therefore, in view of the above situation, there is an urgent need to develop a tunnel drainage device for highway construction to overcome the shortcomings in current practical applications. Summary of the invention

[0045] Compared with the prior art, the beneficial effects of the present invention are:

Multiple blocking assemblies can block the fixed particles entering the suction assembly, prevent them from entering the suction assembly and damaging the main body of the drainage pump, ensure the pumping and drainage quality and efficiency of the main body of the drainage pump, and extend the service life of the main body of the drainage pump;

[0047] Some of the accumulated water discharged from the drain pipe will enter the branch pipe. The branch pipe discharges the accumulated water into the control mechanism through the second hose. The control mechanism quickly discharges the accumulated water into the rotary cleaning mechanism. By quickly discharging the accumulated water into the rotary cleaning mechanism, one end of the rotary cleaning mechanism can be driven to rotate. By rotating one end of the rotary cleaning mechanism, not only can the silt retained on the inner wall of the suction and discharge assembly be scraped off, ensuring the pumping quality and efficiency of the suction and discharge assembly, improving the pumping and drainage efficiency and quality of the drainage device, but also the circular block can be driven to rotate between the annular sleeve and the suction and discharge assembly. The circular block drives multiple barrier components to revolve. When the multiple barrier components are in the revolving state, they will contact the solid particles in the tunnel, thereby triggering the free rotation of the multiple barrier components, causing the multiple barrier components to revolve and rotate simultaneously. In this way, not only can the larger impurities in the accumulated water be effectively intercepted and separated, playing a role in pretreatment and filtration, protecting the pumps, pipes and other key equipment in the drainage system from wear and blockage, ensuring the smooth operation of the drainage system, reducing the burden on the drainage device, and extending its service life, but also a dynamic filtration effect can be formed, forming a dynamic filtration membrane on its surface, making the barrier components not easily blocked by impurities, further enhancing their interception ability for solid particles, protecting the internal structure of the drainage device, and at the same time improving the durability of the drainage device, ensuring the smooth progress of the drainage operation.

Detailed implementation manners

[0061] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0062] The following describes the specific implementation of the present invention in detail with specific embodiments.

[0063] As shown in Figures 1 to 11As shown in the figure, a tunnel drainage device for highway construction provided as an embodiment of the present invention includes a drainage pump main body 100. A water inlet pipe 110 is fixed to the input end of the drainage pump. A first hose 140 is connected to the water inlet pipe 110. One end of the first hose 140 is communicated with a suction and drainage assembly 200. A water outlet pipe 120 is fixed to the output end of the drainage pump. A branch pipe 130 is arranged on one side of the water outlet pipe 120. A second hose 150 is connected to the branch pipe 130. A filter screen can be installed at the connection between the branch pipe 130 and the water outlet pipe 120. The filter screen can filter the water discharged from the water outlet pipe 120 into the branch pipe 130, avoiding damage to the subsequent structure of the device caused by sundries in the water and extending the service life of the drainage device. It further includes:

[0064] A rotary cleaning mechanism 400. The rotary cleaning mechanism 400 is located directly above the suction and drainage assembly 200 and is fixedly connected to the outer wall of the suction and drainage assembly 200. One end of the rotary cleaning mechanism 400 extends into the suction and drainage assembly 200 and abuts against the inner wall of the suction and drainage assembly 200.

[0065] A control mechanism 500. The control mechanism 500 is arranged on one side of the rotary cleaning mechanism 400 and is fixedly connected to the rotary cleaning mechanism 400. One end of the control mechanism 500 is communicated with the branch pipe 130 through the second hose 150. The other end of the control mechanism 500 is respectively communicated with the suction and drainage assembly 200 and the rotary cleaning mechanism 400.

[0066] A blocking mechanism 300. The blocking mechanism 300 includes an annular sleeve 310, a circular block 320 and a blocking assembly 330. The annular sleeve 310 is fixed below the suction and drainage assembly 200 by bolts. The circular block 320 is located between the suction and drainage assembly 200 and the annular sleeve 310 and is rotatably connected to both of them. The other end of the rotary cleaning mechanism 400 is concentric with the circular block 320 and is fixedly connected to it. A square groove 321 is opened in the middle of the circular block 320. A plurality of installation grooves 322 are symmetrically opened at both ends of the circular block 320. One side of the installation groove 322 is communicated with the square groove 321. The blocking assemblies 330 are equidistantly distributed in the square groove 321, and both ends of the blocking assembly 330 are freely rotatably installed in the installation grooves 322 located on both sides of the square groove 321.

[0067] The drainage pump main body 100 can quickly suck the accumulated water inside the tunnel through the water inlet pipe 110, the first hose 140 and the suction and drainage assembly 200, and quickly discharge it outside the tunnel through the water outlet pipe 120. A plurality of blocking assemblies 330 can block the fixed particles entering the suction and drainage assembly 200, avoiding them from entering the suction and drainage assembly 200 and damaging the drainage pump main body 100, ensuring the pumping and drainage quality and efficiency of the drainage pump main body 100, and extending the service life of the drainage pump main body 100.

[0068] Part of the accumulated water discharged from the drain pipe 120 will enter the branch pipe 130. The branch pipe 130 discharges the accumulated water into the control mechanism 500 through the second hose 150. The control mechanism 500 quickly discharges the accumulated water into the rotary cleaning mechanism 400. By quickly discharging the accumulated water into the rotary cleaning mechanism 400, one end of the rotary cleaning mechanism 400 can be driven to rotate. By rotating, one end of the rotary cleaning mechanism 400 can not only scrape the silt remaining on the inner wall of the suction and discharge assembly 200, ensure the pumping quality and efficiency of the suction and discharge assembly 200, and improve the drainage and pumping efficiency and quality of the drainage device, but also drive the circular block 320 to rotate between the annular sleeve 310 and the suction and discharge assembly 200. The circular block 320 drives a plurality of blocking components 330 to revolve. Under the revolving state, the plurality of blocking components 330 will contact the solid particles in the tunnel, thereby triggering the plurality of blocking components 330 to rotate freely, so that the plurality of blocking components 330 revolve and rotate simultaneously. In this way, not only can the larger impurities in the accumulated water be effectively intercepted and separated, playing a role in pretreatment and filtration, protecting the pumps, pipelines and other key equipment in the drainage system from wear and blockage, ensuring the smooth operation of the drainage system, reducing the burden on the drainage device, and extending its service life, but also a dynamic filtration effect can be formed. When the blocking component 330 rotates, it can drive the relatively light-quality water or air around it to rotate accordingly, thereby forming a dynamic filtration membrane on its surface, making it difficult for the blocking component 330 to be blocked by impurities, further enhancing its interception ability for solid particles, protecting the internal structure of the drainage device, and at the same time improving the durability of the drainage device, ensuring the smooth progress of the drainage operation.

[0069] In this embodiment, the branch pipe 130 is welded to one side of the drain pipe 120. The lengths of the first hose 140 and the second hose 150 can be selected according to the distance between the drainage pump main body 100 and the suction and discharge assembly 200. The connections between the above pipelines are all fixedly connected by flanges and bolts.

[0070] As Figures 4 to 11 shown, as a preferred embodiment of the present invention, the blocking component 330 includes a fixed seat 331, a sealing plate 332, a first spring 333, a fixed shaft 334 and a blocking cylinder 335. The fixed seat 331 is vertically slidably installed in the installation groove 322. The sealing plate 332 is locked on the surface of the installation groove 322. A first spring 333 is installed between the sealing plate 332 and the fixed seat 331. The blocking cylinders 335 and the fixed shafts 334 are evenly distributed in the square groove 321. The blocking cylinder 335 is rotatably installed on the outer wall of the fixed shaft 334. Filter holes 336 are distributed on the surface of the blocking cylinder 335. Both ends of the fixed shaft 334 extend into two symmetric installation grooves 322 and are fixedly connected to the two fixed seats 331 in the two installation grooves 322 respectively.

[0071] As shown Figures 4 to 11 In a preferred embodiment of the present invention, sector-shaped scraping plates 337 are also equidistantly distributed in the square groove 321. Both ends of the sector-shaped scraping plates 337 are fixed to both ends of the fixed shaft 334. The sector-shaped scraping plates 337 are located outside the barrier cylinder 335, and the inner wall of the sector-shaped scraping plates 337 is close to the outer wall of the barrier cylinder 335. The inner diameter of the sector-shaped scraping plates 337 is slightly larger than the outer diameter of the barrier cylinder 335.

[0072] In this embodiment, during the process of the drainage and suction assembly 200 sucking the accumulated water in the tunnel, the accumulated water in the tunnel enters the drainage and suction assembly 200 through the spaces between the two barrier cylinders 335 and the filter holes 336 on the barrier cylinders 335. The barrier cylinders 335 can block the fixed particles entering the drainage and suction assembly 200, prevent them from entering the drainage and suction assembly 200 and damaging the main body 100 of the drainage pump, ensure the drainage quality and efficiency of the main body 100 of the drainage pump, and extend the service life of the main body 100 of the drainage pump;

[0073] When the circular block 320 rotates with the rotary cleaning mechanism 400, the circular block 320 drives the multiple barrier cylinders 335 to revolve synchronously. The barrier cylinders 335 in the revolving state will contact the solid particles distributed at their bottoms, and the frictional force between the two will drive the barrier cylinders 335 to freely rotate on the fixed shaft 334, so that the sector-shaped scraping plates 337 can scrape the impurities remaining on the surfaces of the barrier cylinders 335, ensuring the filtration efficiency and filtration quality of the barrier cylinders 335 themselves. Moreover, through the revolving and rotating methods, the barrier cylinders 335 can not only effectively intercept and separate the larger impurities in the accumulated water, play a role in pretreatment and filtration, protect the pumps, pipelines and other key equipment in the drainage system from abrasion and blockage, ensure the smooth operation of the drainage system, reduce the burden on the drainage device, extend its service life, but also form a dynamic filtration effect, form a dynamic filtration membrane on its surface, make the barrier assembly 330 not easily blocked by impurities, further enhance its interception ability for solid particles, protect the internal structure of the drainage device, improve the durability of the drainage device at the same time, and ensure the smooth progress of the drainage operation;

[0074] At the same time, to prevent the fixed particles from damaging the barrier cylinders 335 in the rotating state, when the barrier cylinders 335 rotate and contact the fixed particles, the fixed particles will drive the fixed shaft 334 to move upward through the barrier cylinders 335. The fixed shaft 334 squeezes the first spring 333 through the fixed seat 331. At the same time, the first spring 333 can also keep the barrier cylinders 335 in contact with the solid particles during the rotation process through its own elastic force.

[0075] In a preferred embodiment, both ends of the fixed shaft 334 can be locked in the fixed seat 331 by screws or set screws;

[0076] The barrier cylinder 335 preferably adopts a cylindrical barrel structure, and one side of the barrier cylinder 335 protrudes outside the annular sleeve 310, and its vertical height is lower than that of the annular sleeve 310 and the suction and discharge assembly 200.

[0077] Such as Figures 1 to 8 As shown, as a preferred embodiment of the present invention, the suction and discharge assembly 200 includes a suction and discharge main pipe 210, a suction and discharge hopper 220, a suction and discharge sub-pipe 230, and a filter plate 240. One end of the suction and discharge main pipe 210 is connected to the first hose 140, and the other end of the suction and discharge main pipe 210 is connected to the suction and discharge hopper 220. Suction and discharge sub-pipes 230 connected to the suction and discharge hopper 220 are installed on both sides of the suction and discharge main pipe 210. The suction and discharge main pipe 210 is also connected to the control mechanism 500. Filter plates 240 are fixed to one ends of the suction and discharge main pipe 210 and the suction and discharge sub-pipes 230 close to the suction and discharge hopper 220. A rotary cleaning mechanism 400 is installed directly above the suction and discharge hopper 220, and an annular sleeve 310 is installed directly below the suction and discharge hopper 220.

[0078] In this embodiment, the suction and discharge hopper 220 is located inside the tunnel water accumulation. The drainage pump main body 100 can suck the water accumulation in the suction and discharge hopper 220 into the suction and discharge main pipe 210 and the suction and discharge sub-pipes 230 by suction. The water accumulation then enters the first hose 140 through the suction and discharge main pipe 210 and the suction and discharge sub-pipes 230. The water accumulation in the first hose 140 enters the drainage pump main body 100 through the water inlet pipe 110, and the drainage pump main body 100 quickly discharges the water accumulation inside it out of the tunnel through the drain pipe 120, thereby realizing the rapid drainage operation of the tunnel;

[0079] Chamfers are provided at the positions where the suction and discharge main pipe 210 is connected to the suction and discharge hopper 220 and at the positions where the drainage sub-pipe is connected to the drainage pipe.

[0080] In a preferred embodiment, the diameter of the suction and discharge main pipe 210 is larger than the diameter of the suction and discharge sub-pipe 230. The suction and discharge sub-pipe 230 preferably adopts a bent pipe, and the suction and discharge sub-pipe 230 is fixed to the suction and discharge main pipe 210 by welding. The suction and discharge hopper 220 preferably adopts a circular barrel structure with an opening on one side, and an annular sleeve 310 is installed at the opening position on one side of the suction and discharge hopper 220.

[0081] Such as Figures 1 to 9As shown, as a preferred embodiment of the present invention, the rotary cleaning mechanism 400 includes an installation cylinder 410, a fixing frame 420, a rotary assembly 430, and a cleaning assembly 440. The installation cylinder 410 is fixed above the suction hopper 220 through the fixing frame 420. A rotary assembly 430 is fixed inside the installation cylinder 410. One side of the installation cylinder 410 is connected to the control mechanism 500, and the other side of the installation cylinder 410 is communicated with the suction hopper 220. One end of the rotary assembly 430 extends into the suction hopper 220 and is connected to the cleaning assembly 440. One end of the cleaning assembly 440 intermittently contacts the filter plate 240 and the inner wall of the suction hopper 220, and the other end of the cleaning assembly 440 is concentric and fixedly connected to the circular block 320.

[0082] In this embodiment, a part of the accumulated water discharged from the drain pipe 120 will enter the branch pipe 130. The branch pipe 130 discharges the accumulated water into the control mechanism 500 through the second hose 150. The control mechanism 500 quickly discharges the accumulated water into the installation cylinder 410 and drives the rotary assembly 430 to rotate. The rotary assembly 430 drives the cleaning assembly 440 to rotate. By rotating, the cleaning assembly 440 can not only intermittently scrape the silt on the filter plate 240 and the inner wall of the suction hopper 220, ensure the pumping quality and pumping efficiency of the suction assembly 200, and improve the pumping and drainage efficiency and quality of the drainage device, but also drive the circular block 320 to rotate between the annular sleeve 310 and the suction hopper 220. The circular block 320 can drive a plurality of barrier cylinders 335 to revolve synchronously, so that the barrier cylinders 335 revolve and rotate simultaneously, effectively intercept and separate the larger impurities in the accumulated water, play a role in pretreatment and filtration, protect the pumps, pipes and other key equipment in the drainage system from wear and blockage, and ensure the smooth operation of the drainage system.

[0083] In a preferred embodiment, the installation cylinder 410 preferably adopts a structure in the shape of a circular block 320 with a hollow interior.

[0084] As Figures 4 to 9 shown, as a preferred embodiment of the present invention, the rotary assembly 430 includes an impeller 431 and a rotary shaft 432. One end of the rotary shaft 432 is located inside the installation cylinder 410 and is fixedly connected to the impeller 431, and the other end of the rotary shaft 432 extends into the suction hopper 220 and is connected to the cleaning assembly 440.

[0085] In this embodiment, the control mechanism 500 quickly discharges the accumulated water into the installation cylinder 410 and drives the impeller 431 to rotate. The impeller 431 drives the rotary shaft 432 to rotate, and the rotary shaft 432 drives the cleaning assembly 440 to rotate.

[0086] As Figures 4 to 9As shown, as a preferred embodiment of the present invention, the cleaning assembly 440 includes a fixed sleeve 441, a rotating frame 442, mounting holes 443, sliding columns 444, square scraping plates 445 and second springs 446. The fixed sleeve 441 is located inside the suction hopper 220 and is fixedly connected to the rotating shaft 432. The rotating frames 442 are circumferentially distributed on the outer wall of the fixed sleeve 441. One side of each rotating frame 442 is parallel to the inner wall of the suction hopper 220 and the filter plate 240. Mounting holes 443 are vertically and equidistantly formed on one side of the rotating frame 442, and the bottom of the rotating frame 442 is fixedly connected to the circular block 320. The sliding columns 444 are slidably mounted in the mounting holes 443. Square scraping plates 445 are fixed to one ends of the sliding columns 444 close to the filter plate 240 and the inner wall of the suction hopper 220. Second springs 446 are mounted between the other ends of the sliding columns 444 and the rotating frame 442.

[0087] In this embodiment, the rotating shaft 432 drives the rotating frame 442 to rotate. The rotating frame 442 simultaneously drives the sliding columns 444, the square scraping plates 445, the second springs 446 and the circular block 320 to rotate. The second springs 446 drive the square scraping plates 445 to always abut against the inner wall of the suction hopper 220 or the filter plate 240 through their own elastic forces. The square scraping plates 445 can intermittently scrape the silt on the inner wall of the filter plate 240 and the suction hopper 220 by rotating, ensuring the pumping quality and pumping efficiency of the suction assembly 200, and improving the pumping and drainage efficiency and quality of the drainage device.

[0088] During the process of the square scraping plate 445 scraping the silt on the filter plate 240, the square scraping plate 445 first enters from the chamfer position on one side of the filter plate 240 and scrapes the silt by rotating, and finally moves out from the chamfer position on the other side of the filter plate 240 and scrapes the silt on the inner wall of the suction hopper 220.

[0089] In a preferred embodiment, the square scraping plates 445 can be replaced with other specifications and shapes that meet the usage requirements, such as trapezoidal or conical.

[0090] As Figures 1 to 4As shown, as a preferred embodiment of the present invention, the control mechanism 500 includes a water inlet cylinder 510, a first connecting pipe 520, a control frame 530, a conveying pipe 540, a second connecting pipe 550, and an adjustment assembly 560. The water inlet cylinder 510 is fixed on the fixed frame 420 through the control frame 530, and the water inlet cylinder 510 is located on one side of the installation cylinder 410. A first connecting pipe 520 is fixedly connected to the top of one side of the water inlet cylinder 510. The first connecting pipe 520 is communicated with the second hose 150. A second connecting pipe 550 is fixed to the bottom of one side of the water inlet cylinder 510. One end of the second connecting pipe 550 is communicated with the main suction and discharge pipe 210. A conveying pipe 540 is fixed to the other side of the water inlet cylinder 510. The conveying pipe 540 is communicated with the installation cylinder 410. An adjustment assembly 560 is vertically slidably installed in the water inlet cylinder 510. The diameters of the second connecting pipe 550 and the conveying pipe 540 are the same, and the sum of their diameters is equal to the diameter of the first connecting pipe 520.

[0091] As Figures 2 to 4 As shown, as a preferred embodiment of the present invention, the adjustment assembly 560 includes a fixed column 561, a sliding member 562, and a third spring 563. The fixed column 561 is vertically fixed in the water inlet cylinder 510 and is parallel to the water inlet cylinder 510. A sliding member 562 that contacts the inner wall of the water inlet cylinder 510 is slidably installed on the fixed column 561. One end of the sliding member 562 is connected to the bottom of the inner wall of the water inlet cylinder 510 through the third spring 563. The sliding member 562 preferably adopts a rotating cylinder structure with a U-shaped cross-section.

[0092] In this embodiment, part of the accumulated water discharged from the drain pipe 120 will enter the branch pipe 130. The branch pipe 130 discharges the accumulated water into the water inlet cylinder 510 through the second hose 150 and the first connecting pipe 520. In the initial state, the third spring 563 drives the sliding member 562 to move upward through its own elastic force, so that the sliding member 562 can block the second connecting pipe 550 at the bottom of the water inlet cylinder 510, which can prevent the water in the water inlet cylinder 510 from entering the main suction and discharge pipe 210, thereby ensuring that the water in the water inlet cylinder 510 can normally flow into the conveying pipe 540 and ensuring that the rotary cleaning mechanism 400 can work stably;

[0093] When the pumping efficiency of the suction and discharge assembly 200 is normal, since the diameter of the first connecting pipe 520 is equal to the sum of the diameters of the second connecting pipe 550 and the conveying pipe 540, the accumulated water in the water inlet cylinder 510 continuously increases. The continuously increasing accumulated water presses on the third spring 563, so that the sliding member 562 can move downward in the water inlet cylinder 510, thereby releasing the blockage of the second connecting pipe 550. While ensuring the stable output flow of the conveying pipe 540, the excess accumulated water in the water inlet cylinder 510 can be discharged into the main suction and discharge pipe 210;

[0094] When the pumping efficiency of the pumping and suction assembly 200 is poor, the accumulated water in the water inlet cylinder 510 continuously decreases. The third spring 563 drives the sliding member 562 to move upward by releasing its own elastic force, so that the sliding member 562 can not only restore the blockage of the second connecting pipe 550, but also push the accumulated water above it, ensuring that the output flow of the conveying pipe 540 is always stable, and further ensuring that it can stably drive the impeller 431 to rotate. In this way, no matter whether the pumping and suction assembly 200 pumps water normally or not, the accumulated water in the water inlet cylinder 510 can always bring stable output power to the impeller 431, ensuring the stable rotation of the cleaning assembly 440 and the blocking assembly 330.

[0095] The working principle of the present invention is as follows:

[0096] Some of the accumulated water discharged from the drain pipe 120 will enter the branch pipe 130. The branch pipe 130 discharges the accumulated water into the water inlet cylinder 510 through the second hose 150 and the first connecting pipe 520. In the initial state, the third spring 563 drives the sliding member 562 to move upward by its own elastic force, so that the sliding member 562 can block the second connecting pipe 550 at the bottom of the water inlet cylinder 510, which can prevent the water in the water inlet cylinder 510 from entering the main pumping and suction pipe 210, thus ensuring that the water in the water inlet cylinder 510 can normally flow into the conveying pipe 540;

[0097] When the pumping efficiency of the pumping and suction assembly 200 is normal, since the diameter of the first connecting pipe 520 is equal to the sum of the diameters of the second connecting pipe 550 and the conveying pipe 540, the accumulated water in the water inlet cylinder 510 continuously increases. The continuously increasing accumulated water presses on the third spring 563, so that the sliding member 562 can move downward in the water inlet cylinder 510, thereby releasing the blockage of the second connecting pipe 550. While ensuring the stable output flow of the conveying pipe 540, the excess accumulated water in the water inlet cylinder 510 can be discharged into the main pumping and suction pipe 210; when the pumping efficiency of the pumping and suction assembly 200 is poor, the accumulated water in the water inlet cylinder 510 continuously decreases. The third spring 563 drives the sliding member 562 to move upward by releasing its own elastic force, so that the sliding member 562 can not only restore the blockage of the second connecting pipe 550, but also push the accumulated water above it, ensuring that the output flow of the conveying pipe 540 is always stable, and further ensuring that it can stably drive the impeller 431 to rotate. In this way, no matter whether the pumping and suction assembly 200 pumps water normally or not, the accumulated water in the water inlet cylinder 510 can always bring stable output power to the impeller 431;

[0098] The impeller 431 drives the rotating shaft 432 to rotate, and the rotating shaft 432 drives the rotating frame 442 to rotate. The rotating frame 442 drives the sliding column 444, the square scraper 445, the second spring 446 and the circular block 320 to rotate at the same time. The second spring 446 drives the square scraper 445 to always contact the inner wall of the suction bucket 220 or the filter plate 240 through its own elastic force. The square scraper 445 can intermittently scrape the sludge on the filter plate 240 and the inner wall of the suction bucket 220 by rotating, thereby ensuring the pumping quality and efficiency of the suction and discharge assembly 200, and improving the pumping efficiency and quality of the drainage device;

[0099] The circular block 320 drives multiple barrier cylinders 335 to revolve synchronously. The barrier cylinder 335 in the revolving state will contact the solid particles distributed at its bottom, and the friction between the two will drive the barrier cylinder 335 to rotate freely on the fixed shaft 334, so that the fan-shaped scraper 337 can scrape the impurities retained on the surface of the barrier cylinder 335, ensuring the filtering efficiency and filtering quality of the barrier cylinder 335 itself. In addition, the barrier cylinder 335 can not only effectively intercept and separate the larger impurities in the accumulated water through the revolution and rotation, play a role in pretreatment and filtration, and protect the pumps, pipes and other key equipment in the drainage system from wear and blockage, but also form a dynamic filtration effect, forming a layer of dynamic filtration membrane on its surface, so that the barrier component 330 is not easily blocked by impurities, further enhancing its ability to intercept solid particles.

[0100] At the same time, in order to prevent the fixed particles from damaging the barrier cylinder 335 in a rotating state, when the barrier cylinder 335 rotates and contacts the fixed particles, the fixed particles will drive the fixed shaft 334 to move upward through the barrier cylinder 335, and the fixed shaft 334 will squeeze the spring 1 333 through the fixed seat 331. At the same time, the spring 1 333 can also keep the barrier cylinder 335 in contact with the solid particles during the rotation process through its own elastic force;

[0101] The above is the working principle of the tunnel drainage device used in the construction of the expressway.

[0102] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
