Description

Technical Field

[0001] This application relates to the technical field of tunnel blind pipe cleaning devices, and more specifically, to a cleaning device for crystalline substances on tunnel drainage blind pipes. Background Technique

[0002] Tunnel drainage blind pipes are an important part of the tunnel drainage system and play a crucial role in tunnel drainage projects. Specifically, the fissure water in the tunnel rock mass leaks down along the geotextile behind the waterproof board and the gap between the geotextile and the initial support surface of the tunnel to the drainage blind pipe, and is discharged into the tunnel drainage ditch through the blind pipe in a timely manner. Crystalline substances and impurities adhering to the inner wall of the tunnel drainage pipe blind pipe often require regular flushing of the blind pipe to ensure smooth drainage inside the blind pipe.

[0003] The currently commonly used flushing method is high-pressure water gun flushing. However, the high-pressure water gun has a good cleaning effect on the crystals and impurities adhering to the inner wall near the blind pipe, but it is difficult to flush away the crystals and other adhering impurities remaining on the inner wall at the distal end of the blind pipe, resulting in a poor flushing effect at the distal end of the blind pipe.

Detailed implementation manners

[0033] Next, the technical solutions in the embodiments of the present application will be described with reference to the accompanying drawings in the embodiments of the present application.

[0034] To make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0035] Accordingly, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the claimed present application, but merely represents selected embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts fall within the scope of protection of the present application.

[0036] A crystallized substance cleaning device for a tunnel drainage blind pipe according to an embodiment of the present application will be described below with reference to the accompanying drawings.

[0037] Please refer to Figures 1 - 5 , a crystallized substance cleaning device for a tunnel drainage blind pipe according to an embodiment of the present application, includes: a water outlet pipe main body part 10, a rotation driving part 20, and a rotary flushing and cleaning part 30.

[0038] Among them, the whole cleaning device can be inserted into the drainage blind pipe of the tunnel. The rotation driving part 20 drives the rotary flushing and cleaning part 30 to rotate to clean the crystallized substances and other impurities attached to the inner wall of the blind pipe. At the same time, the water outlet pipe main body part 10 can cooperate with the rotation driving part 20 and the rotary flushing and cleaning part 30 to flush the area of the scraping and cleaning part at the same time, and gradually insert the cleaning device deep into the blind pipe to efficiently clean and flush the inner wall.

[0039] The water outlet pipe main body part 10 includes a water guide cylinder pipe 110, a water inlet pipe 120, a collar seat 130, and a connecting pipe 140. The water inlet pipe 120 is communicated with the tail end of the water guide cylinder pipe 110. The collar seat 130 is fixedly sleeved outside the water guide cylinder pipe 110, and the collar seat 130 and the water guide cylinder pipe 110 can be fixedly arranged by welding. One end of the connecting pipe 140 is communicated with the water guide cylinder pipe 110. The rotation driving part 20 includes a seat frame 210, a first motor 220, a disc 230, and a rear seat shell 240. The first motor 220 is installed inside the seat frame 210. The output shaft end of the first motor 220 rotates through the seat frame 210, and the disc 230 is arranged on the output shaft rod of the first motor 220. The rear seat shell 240 is fixedly arranged on the front side of the seat frame 210 and is rotationally matched with the disc 230. The disc 230 is provided with a water passing hole 250 communicated with the rear seat shell 240. The output shaft end of the first motor 220 rotates through the rear seat shell 240, and the other end of the connecting pipe 140 is communicated with the rear seat shell 240. The rotary flushing and cleaning part 30 includes a conical disc shell 310 and a scraping member 320. The conical disc shell 310 is installed at the front end of the disc 230, and the scraping member 320 is installed through the radial position of the conical disc shell 310.

[0040] The working principle of the crystallized substance cleaning device for the tunnel drainage blind pipe is as follows: The cleaning device is inserted from the blind pipe port of the tunnel, and the device is introduced into it through the water inlet pipe 120. The whole cleaning device gradually moves forward in the blind pipe. During the movement, the first motor 220 in the rotation driving part 20 drives the disc 230 to rotate. The rotating disc 230 drives the conical disc housing 310 and the scraping part 320 to rotate. The rotating scraping part 320 can clean the crystals and other impurities in the tunnel blind pipe. While the first motor 220 drives the scraping part 320 to rotate to clean the inner wall of the blind pipe, the cleaning solution is introduced into the inside of the water guiding cylinder pipe 110 through the water inlet pipe 120. The cleaning solution enters the inside of the rear seat housing 240 through the water guiding cylinder pipe 110 and the connecting pipe 140. The cleaning solution entering the inside of the rear seat housing 240 then enters the conical disc housing 310 through the water passing holes 250. Finally, the cleaning solution inside the conical disc housing 310 can be released outward through the scraping part 320. That is, when the scraping part 320 rotates to clean the crystal impurities on the inner wall of the blind pipe, it can also perform precise flushing synchronously. Flushing while scraping and cleaning will have a better cleaning efficiency. This cleaning device can gradually extend and move towards the end of the blind pipe inside the tunnel blind pipe for synchronous scraping and flushing treatment, and has a better cleaning efficiency compared with the traditional high-pressure water gun flushing method.

[0041] When the traditional high-pressure water gun is inserted into the blind pipe for flushing, it can only spray the solution along the axial position of the blind pipe to flush the impurities inside the blind pipe. However, the scraping part 320 in the design of this cleaning device rotates and flushes the impurities attached to the inner wall of the blind pipe in the radial position. While gradually moving forward inside the blind pipe, it can also flush the inner wall of the blind pipe along the radial position, having a better cleaning and flushing effect.

[0042] In the above specific implementation manner, please refer to Figure 2 and Figure 6 As shown in the figure, multiple sets of scraping parts 320 are provided, and the multiple sets of scraping parts 320 are arranged in a circular array and are installed in cooperation with the conical disc housing 310. The scraping part 320 includes a straight pipe 321, a scraper 322, a limiting ring 323, and a spring 324. The straight pipe 321 movably penetrates the side wall of the conical disc housing 310. A cavity slot 325 is provided inside the scraper 322. The limiting ring 323 and the scraper 322 are respectively connected and arranged at both ends of the straight pipe 321. The spring 324 is sleeved outside the straight pipe 321 between the limiting ring 323 and the inner wall of the conical disc housing 310.

[0043] The specific cleaning and flushing method of the scraping part 320 is as follows: When the cleaning solution enters the inside of the conical disc housing 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 slot 325 inside the scraper 322. It can achieve that while the scraper 322 rotates to scrape and clean, it can also perform efficient flushing through the high-pressure liquid discharged from the cavity slot 325.

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

[0045] When specifically setting, the scraper 322 is arranged in a flat nozzle shape, and the outer edge of the scraper 322 is arranged in an arc shape, and the scraper 322 is arranged at an inclined angle with respect to the end face of the conical disk shell 310. The inclined setting and the arc angle setting both reduce the friction between the scraper 322 and the inner wall of the blind pipe, and the scraper 322 can rotate more smoothly.

[0046] Furthermore, small holes are provided on the side of the conical disk shell 310, and the straight pipe 321 movably penetrates through the small holes. A support ring is arranged on the inner wall of the conical disk shell 310 at the position of the small holes, the straight pipe 321 movably penetrates through the support ring, and the spring 324 is located between the limiting ring 323 and the support ring. The opposite surfaces of the support ring and the limiting ring 323 are both flat surfaces, and the spring 324 is not easily deformed and deflected along the axial direction when being repeatedly squeezed.

[0047] Specifically, a connection port is arranged on the outer side of the rear seat shell 240, and one end of the connecting pipe 140 far from the water guide cylinder pipe 110 is communicated with the connection port. A through hole 260 is arranged on the end face of the rear seat shell 240, and the shaft end of the first motor 220 rotates through the rear seat shell 240.

[0048] In the above specific implementation manner, please refer to Figure 2 and Figure 7 , the tunnel drainage blind pipe crystallite cleaning device further includes an external protection component 40, and the external protection component 40 includes a front sheath shell 410 and a rear sheath shell 420. The front sheath shell 410 and the rear sheath shell 420 are respectively sleeved outside the rotation driving part 20 and the water guide cylinder pipe 110, and the opposite ends of the front sheath shell 410 and the rear sheath shell 420 are fixedly arranged with the collar seat 130. A through port 440 is arranged at one end of the rear sheath shell 420 far from the front sheath shell 410, and the water guide cylinder pipe 110 penetrates through the through port 440.

[0049] The front sheath shell 410 and the rear sheath shell 420 are arranged to protect components such as the water guide cylinder pipe 110 and the rotation driving part 20 inside the device, and at the same time, they also have a blocking effect on the water source after cleaning inside the blind pipe, and can play a role in sealing and protecting the components in the rotation driving part 20.

[0050] When the above-mentioned crystal cleaning device for tunnel drainage blind pipes moves forward inside the blind pipe, it mainly relies on the water inlet pipe 120 to push the cleaning device forward. If a flexible hose is used for the water inlet pipe 120, it will be difficult to push the cleaning device forward. If a rigid straight pipe is used, the overall rigid length of the device will increase. Due to the limited space at the end of the blind pipe, the flexibility of the straight pipe extending into the blind pipe for a long distance is limited.

[0051] Another implementation of the crystal cleaning device for tunnel drainage blind pipes is provided. Please refer to Figure 7 and Figure 8 The crystal cleaning device for tunnel drainage blind pipes further includes a valve part 50. The valve part 50 includes a valve seat 510, a ball core 520, a valve stem 530 and a second motor 540. The water guide cylinder tube 110 includes a front cylinder tube and a rear cylinder tube. The two ends of the valve seat 510 are respectively connected and docked with the adjacent ports of the front cylinder tube and the rear cylinder tube of the water guide cylinder tube 110. The valve stem 530 is rotatably arranged with the valve seat 510. The ball core 520 is located inside the valve seat 510 and is connected to the bottom end of the valve stem 530. The second motor 540 is installed on the top of the valve seat 510 to drive the valve stem 530 to rotate. A three-way cavity 560 with a T-shaped structure is arranged inside the ball core 520. A water discharge port 550 is arranged on one side wall of the valve seat 510. Multiple groups of connected tail pipes 430 are arranged at the end of the rear sheath shell 420.

[0052] When the first motor 220 drives the scraping member 320 to rotate to clean the impurities on the inner wall of the blind pipe, at this time, the two ports of the three-way cavity 560 inside the ball core 520 are respectively located at the axial positions of the two ends of the valve seat 510, and the other port of the three-way cavity 560 is opposite to the position of the water discharge port 550. That is, at this time, the cleaning water source introduced from the water inlet pipe 120 into the water guide cylinder tube 110 enters the front cylinder tube from the rear cylinder tube in the water guide cylinder tube 110 through the three-way cavity 560 in the ball core 520 inside the valve seat 510, then enters the conical disc housing 310 through the connecting pipe 140, and finally is discharged from the cavity slot 325 in the scraping member 320 to complete the flushing. When the second motor 540 drives the valve stem 530 to rotate so that the position of the three-way cavity 560 in the ball core 520 inside the valve seat 510 changes to one port of the three-way cavity 560 being communicated with the water discharge port 550 and one port being communicated with the rear cylinder tube. At this time, the cleaning water source will be discharged into the rear sheath shell 420 through the three-way cavity 560 and the water discharge port 550. The over-pressured water source inside the rear sheath shell 420 will be discharged into the blind pipe through the tail pipes 430 at the tail end. The discharged water source has two functions. One is that the discharged water source gives the device a reaction force, which can make the whole cleaning device move forward inside the blind pipe; the other is that the cleaning solution flushing out from the tail end of the tail pipe 430 can flush the impurities cleaned inside the blind pipe to the end of the blind pipe, further enhancing the cleaning effect on the tunnel blind pipe.

[0053] The rotation speed, start and stop of the second motor 540 can be controlled according to the control system of the device, ensuring that while the second motor 540 drives the spherical center 520 to continuously change the position of the three-way cavity opening 560, the two-way adjustment of flushing and movement can be completed.

[0054] If the scraping part 320 and the conical disc housing 310 in the above tunnel drainage blind pipe crystal cleaning device can be adjusted while rotating and tilting and also reciprocatingly moving along, the cleaning efficiency of the inner wall of the tunnel blind pipe can be further improved.

[0055] Please refer to Figure 9 and Figure 10 As shown in [relevant figure numbers], the tunnel drainage blind pipe crystal cleaning device further includes an impact cleaning part 60. The impact cleaning part 60 includes an outer pipe fitting 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 fitting 610 is arranged inside the water guide cylinder pipe 110, and the two ends of the outer pipe fitting 610 and the inner part of the water guide cylinder pipe 110 are arranged in a sealed structure. The sealed structure and the outer pipe fitting 610 and the water guide cylinder pipe 110 form a second water passing cavity layer. The inner rod 640 is slidably arranged inside the outer pipe fitting 610. A sealing component is arranged in the first water passing cavity layer formed between the outer side of the front end of the inner rod 640 and the outer pipe fitting 610. A slot hole 670 communicating with the first water passing cavity layer inside the outer pipe fitting 610 is arranged on the outer wall of the outer pipe fitting 610. The eccentric shaft 630 is rotatably arranged at the tail end of the water guide cylinder pipe 110, and the tail end of the inner rod 640 is eccentrically rotatably arranged with the eccentric shaft 630. The third motor 620 is installed outside the water guide cylinder pipe 110 to drive the eccentric shaft 630 to rotate. The seat plate 650 is fixed at 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 slidably penetrates through the collar seat 130.

[0056] The structural arrangement of the impact cleaning part 60 can ensure that the cleaning water source from the water inlet pipe 120 enters the inside of the water guide cylinder pipe 110 through the slot hole 670 and finally enters the inside of the conical disc housing 310 through the connecting pipe 140. When the first motor 220 drives the conical disc housing 310 and the scraping part 320 to rotate to scrape and flush the inner wall of the blind pipe, the third motor 620 can also be driven to drive the eccentric shaft 630 to rotate. The rotating eccentric shaft 630 drives the inner rod 640 to reciprocate inside the outer pipe fitting 610. That is, finally drives the front seat plate 650, the conical disc housing 310 and the scraping part 320 to reciprocate in the axial position. This moving method can ensure that while the scraping part 320 rotates and flushes to meet the above-mentioned implementation modes, the impurities remaining on the inner wall of the blind pipe can be cleaned by the way of the scraping part 320 and the collar seat 130 moving in the axial position, and the cleaning efficiency of the cleaning device can be further improved.

[0057] The impact cleaning part 60 is mainly arranged inside the water guiding cylinder tube 110 of the cleaning device, with a more compact space design, reducing the space occupied by the device, and it is more beneficial for the overall cleaning device to penetrate into the blind tube for cleaning.

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