Description

Technical Field

[0001] This application relates to the technical field of tunnel blind pipe cleaning devices, and more specifically, to a device for cleaning crystallized material from tunnel drainage blind pipes. Background Technology

[0002] Tunnel drainage blind pipes are an important component of tunnel drainage systems and play a crucial role in tunnel drainage engineering. Specifically, fissure water in the tunnel rock mass seeps down through the gaps between the geotextile behind the waterproofing liner and the tunnel's initial support face, eventually reaching the drainage blind pipes and being promptly discharged into the tunnel drainage ditch. To ensure smooth drainage, the inner walls of the tunnel drainage blind pipes are frequently flushed to remove crystals and impurities.

[0003] The most common flushing method is high-pressure water jet flushing. While high-pressure water jets are effective at cleaning crystals and impurities adhering to the inner wall near the blind pipe, they are not effective at removing crystals and other adhering impurities remaining on the inner wall at the far end of the blind pipe. This results in a poor flushing effect at the far end of the blind pipe. Summary of the Invention

Detailed Implementation

[0033] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0035] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0036] A device for cleaning crystallized material from a tunnel drainage blind pipe according to an embodiment of this application is described below with reference to the accompanying drawings.

[0037] Please see Figures 1-5 A tunnel drainage blind pipe crystal cleaning device according to an embodiment of this application includes: a water outlet pipe body 10, a rotation drive part 20, and a rotation flushing and cleaning part 30.

[0038] The cleaning device can be inserted into the drainage blind pipe of the tunnel. The rotating drive part 20 drives the rotating flushing and cleaning part 30 to rotate and clean the crystals and other impurities attached to the inner wall of the blind pipe. At the same time, the main body part 10 of the water outlet pipe, together with the rotating drive part 20 and the rotating flushing and cleaning part 30, simultaneously flushes the area that has been scraped and cleaned. Gradually, the cleaning device penetrates into the blind pipe to efficiently clean and flush the inner wall.

[0039] The main body 10 of the water outlet pipe includes a water guide tube 110, an inlet pipe 120, a collar seat 130, and a connecting pipe 140. The inlet pipe 120 is connected to the tail end of the water guide tube 110. The collar seat 130 is fixedly sleeved on the outside of the water guide tube 110, and the collar seat 130 and the water guide tube 110 can be fixed by welding. One end of the connecting pipe 140 is connected to the water guide tube 110. The rotation drive part 20 includes a base 210, a first motor 220, a disc 230, and a rear housing 240. The first motor 220 is installed inside the base 210, and the output shaft of the first motor 220 rotates through the base 210. The disc 230 is located on the output shaft of the first motor 220. The rear seat housing 240 is fixed to the front side of the seat frame 210 and rotatably engages with the disc 230. The disc 230 is provided with a water passage hole 250 that communicates with the rear seat housing 240. The output shaft end of the first motor 220 rotatably passes through the rear seat housing 240, and the other end of the connecting pipe 140 is connected to the rear seat housing 240. The rotary flushing and cleaning part 30 includes a conical disc housing 310 and a scraper 320. The conical disc housing 310 is installed at the front end of the disc 230, and the scraper 320 is installed radially through the conical disc housing 310.

[0040] The working principle of the tunnel drainage blind pipe crystallization cleaning device is as follows: The cleaning device is inserted into the port of the tunnel blind pipe, and water is introduced into the device through the inlet pipe 120. The entire cleaning device moves forward gradually in the blind pipe. During the movement, the first motor 220 in the rotation drive part 20 drives the disc 230 to rotate. The rotating disc 230 drives the conical disc shell 310 and the scraper 320 to rotate. The rotating scraper 320 can clean the crystals and other impurities in the tunnel blind pipe. While the first motor 220 drives the scraper 320 to rotate and clean the inner wall of the blind pipe, the cleaning solution is introduced into the water guide pipe 110 through the inlet pipe 120. The cleaning solution enters the rear seat shell 240 through the water guide pipe 110 and the connecting pipe 140. The cleaning solution entering the rear housing 240 then flows through the water inlet 250 into the conical disc housing 310. Finally, the cleaning solution inside the conical disc housing 310 is released outwards via the scraper 320. This means that while the scraper 320 rotates to clean the crystallized impurities on the inner wall of the blind pipe, it also simultaneously performs precise rinsing. This simultaneous scraping and rinsing results in better cleaning efficiency. This cleaning device can gradually extend towards the end of the tunnel blind pipe for simultaneous scraping and rinsing, offering significantly better cleaning efficiency compared to traditional high-pressure water jet rinsing.

[0041] Traditional high-pressure water guns can only spray solution along the axial direction of the blind pipe to rinse away impurities. However, the scraping component 320 in this cleaning device rotates radially to rinse away impurities adhering to the inner wall of the blind pipe. As it moves forward gradually inside the blind pipe, it can also rinse the inner wall of the blind pipe radially, resulting in a better cleaning and rinsing effect.

[0042] In the above specific implementation method, please refer to Figure 2 and Figure 6 The scraping components 320 are arranged in multiple sets, and these sets are arranged in a ring array to cooperate with the conical disc shell 310. Each scraping component 320 includes a straight tube 321, a scraper 322, a limiting ring 323, and a spring 324. The straight tube 321 movably penetrates the side wall of the conical disc shell 310, and the scraper 322 has a cavity 325 inside. The limiting ring 323 and the scraper 322 are respectively connected to both ends of the straight tube 321, and the spring 324 is sleeved on the outside of the straight tube 321 located between the limiting ring 323 and the inner wall of the conical disc shell 310.

[0043] The specific cleaning and rinsing method of the scraper 320 is as follows: After the cleaning solution enters the conical disc shell 310, the high-pressure solution will pass through the limiting ring 323, the straight pipe 321, and the scraper 322, and finally be discharged outward from the cavity opening 325 inside the scraper 322. This allows the scraper 322 to rotate and scrape while cleaning, and also allows for efficient rinsing and cleaning through the high-pressure liquid discharged from the cavity opening 325.

[0044] Because the scraper 322 at the end of the straight tube 321 has a certain weight, when the conical disc 310 drives the scraper 320 to rotate, under the action of centrifugal force, the limiting ring 323 will compress the spring 324. The straight tube 321 and the scraper 322 will move outward a certain distance while rotating, increasing the cleaning diameter of the scraper 320. The advantage of this design is that when the cleaning device moves forward inside the blind tube, the radius of the scraper 320 can increase during rotation, resulting in a better cleaning effect on the inner wall of the blind tube.

[0045] In its specific design, the scraper 322 has a flat-nozzle structure with an arc-shaped outer edge, and the scraper 322 is angled relative to the end face of the conical disc 310. Both the angled design and the arc-shaped edge reduce friction between the scraper 322 and the inner wall of the blind tube, allowing the scraper 322 to rotate more smoothly.

[0046] Furthermore, a small hole is provided on the side of the conical disc shell 310, through which the straight tube 321 movably passes. A support ring is provided on the inner wall of the conical disc shell 310 at the small hole, through which the straight tube 321 movably passes. The spring 324 is located between the limiting ring 323 and the support ring. The opposing surfaces of the support ring and the limiting ring 323 are both flat, so the spring 324 is not easily deformed or deflected along the axial direction when subjected to repeated compression.

[0047] Specifically, a connection port is provided on the outer side of the rear seat housing 240, and the end of the connecting pipe 140 away from the water guide pipe 110 is connected to the connection port. A through hole 260 is provided on the end face of the rear seat housing 240, through which the shaft end of the first motor 220 rotates.

[0048] In the above specific implementation method, please refer to Figure 2 and Figure 7 The tunnel drainage blind pipe crystal cleaning device also includes an external protection component 40, which includes a front sheath 410 and a rear sheath 420. The front sheath 410 and the rear sheath 420 are respectively fitted onto the outside of the rotating drive part 20 and the water guide pipe 110, and the opposite ends of the front sheath 410 and the rear sheath 420 are fixedly set to the collar seat 130. The rear sheath 420 is provided with a through-hole 440 at the end away from the front sheath 410, and the water guide pipe 110 is installed through the through-hole 440.

[0049] The front sheath 410 and the rear sheath 420 are designed to protect the internal components of the device, such as the water guide pipe 110 and the rotation drive part 20. They also block the water source after cleaning inside the blind pipe and provide sealing protection for the components in the rotation drive part 20.

[0050] When the aforementioned tunnel drainage blind pipe crystallization cleaning device moves forward inside the blind pipe, it mainly relies on the water inlet pipe 120 to push the cleaning device forward. If the water inlet pipe 120 is a flexible hose, it will be difficult to advance the cleaning device. If a rigid pipe is used, the overall rigid length of the device will increase. Since the space at the tail end of the blind pipe is limited, the flexibility of the straight pipe entering the blind pipe over a longer distance is limited.

[0051] Another embodiment of the tunnel drainage blind pipe crystallization cleaning device is provided; please refer to [link / reference]. Figure 7 and Figure 8 The tunnel drainage blind pipe crystallization cleaning device also includes a valve section 50, which includes a valve seat 510, a ball core 520, a valve stem 530, and a second motor 540. The water guide pipe 110 includes a front pipe and a rear pipe. The two ends of the valve seat 510 are respectively connected to the near ports of the front and rear pipes of the water guide pipe 110. The valve stem 530 is rotatably mounted to the valve seat 510. The ball core 520 is located inside the valve seat 510 and connected to the bottom end of the valve stem 530. The second motor 540 is mounted on the top of the valve seat 510 to drive the valve stem 530 to rotate. The ball core 520 has a T-shaped three-way cavity 560 inside. A drain port 550 is provided on one side wall of the valve seat 510, and multiple interconnected tailpipes 430 are provided at the tail end of the rear sheath 420.

[0052] When the first motor 220 drives the scraper 320 to rotate and clean impurities from the inner wall of the blind pipe, the two ends of the three-way cavity 560 inside the ball core 520 are located at the axial positions of both ends of the valve seat 510, and the other end of the three-way cavity 560 is opposite to the position of the drain port 550. At this time, the cleaning water source is introduced into the guide tube 110 through the inlet pipe 120, enters the front tube through the three-way cavity 560 in the ball core 520 inside the valve seat 510 from the rear tube of the guide tube 110, and then enters the conical disc shell 310 through the connecting pipe 140, finally exiting from the cavity opening 325 in the scraper 320 to complete the rinsing. When the second motor 540 drives the valve stem 530 to rotate, causing the position of the three-way cavity 560 in the ball core 520 inside the valve seat 510 to change so that one end of the three-way cavity 560 is connected to the drain port 550 and the other end is connected to the rear tube. At this point, the cleaning water will be discharged into the rear sheath 420 through the three-way port 560 and the drain port 550. The overpressurized water inside the rear sheath 420 will be discharged into the blind pipe through the tail pipe 430 at the tail end. The discharged water has two functions: firstly, the discharged water provides a recoil force to the device, allowing the entire cleaning device to move forward inside the blind pipe; secondly, the cleaning solution flushed out from the tail end of the tail pipe 430 can flush out the impurities cleaned inside the blind pipe towards the tail end, further enhancing the cleaning effect on the tunnel blind pipe.

[0053] The rotation speed and start / stop of the second motor 540 can be controlled by the device's control system, ensuring that the second motor 540 drives the ball center 520 to continuously change the position of the three-way cavity 560, thereby completing the bidirectional adjustment of rinsing and movement.

[0054] If the scraping component 320 and the conical disc shell 310 in the above-mentioned tunnel drainage blind pipe crystal cleaning device can be adjusted by reciprocating movement while rotating and tilting, the cleaning efficiency of the inner wall of the tunnel blind pipe can be further improved.

[0055] Please see Figure 9 and Figure 10 The tunnel drainage blind pipe crystallization cleaning device also includes an impact cleaning section 60, which includes an outer pipe 610, a third motor 620, an eccentric shaft 630, an inner rod 640, a seat plate 650, and a limiting rod 660. The outer pipe 610 is located inside the water guide pipe 110, and both ends of the outer pipe 610 and the water guide pipe 110 are sealed. The sealing structure, the outer pipe 610, and the water guide pipe 110 form a second water passage cavity layer. The inner rod 640 is slidably disposed inside the outer pipe 610. The outer front end of the inner rod 640 and the outer pipe 610 form a first water passage cavity layer in which a sealing component is provided. The outer wall of the outer pipe 610 is provided with a slot 670 that communicates with the first water passage cavity layer inside the outer pipe 610. An eccentric shaft 630 is rotatably mounted at the tail end of the water guide tube 110, and the tail end of the inner rod 640 is eccentrically mounted to the eccentric shaft 630. A third motor 620 is installed outside the water guide tube 110 to drive the eccentric shaft 630 to rotate. A seat plate 650 is fixed to the front end of the inner rod 640 and connected to the seat frame 210. One end of the limiting rod 660 is connected to the seat plate 650, and the limiting rod 660 slides through the collar seat 130.

[0056] The impact cleaning section 60 is designed to ensure that clean water from the inlet pipe 120 enters the water guide pipe 110 through the slot 670, and finally enters the conical shell 310 through the connecting pipe 140. While the first motor 220 drives the conical shell 310 and the scraper 320 to rotate and scrape and rinse the inner wall of the blind pipe, the third motor 620 also drives the eccentric shaft 630 to rotate. The rotating eccentric shaft 630 causes the inner rod 640 to reciprocate within the outer pipe 610. This ultimately causes the front seat plate 650, the conical shell 310, and the scraper 320 to reciprocate axially. This movement ensures that the rotation and rinsing of the scraper 320 meet the above-described implementation requirements, and also cleans residual impurities on the inner wall of the blind pipe by moving the scraper 320 and the three sets of ring seats 130 axially, further improving the cleaning efficiency of the cleaning device.

[0057] The impact cleaning section 60 is mainly installed inside the water guide pipe 110 of the cleaning device, which has a more compact space design, reduces the space occupied by the device, and makes it more advantageous for the entire cleaning device to be inserted into the blind pipe for cleaning.

[0058] It should be noted that the specific models and specifications of the first motor 220, the second motor 540, and the third motor 620 mentioned above need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail here. The power supply and principle of the first motor 220, the second motor 540, and the third motor 620 are clear to those skilled in the art, and will not be described in detail here.
