The precipitation crystals have a certain hardness, which block the drainage pipes and cause the failure of the tunnel drainage system. Therefore, it is necessary to regularly clean the drainage pipes to remove the precipitation crystals.

[0003] Since the drainage pipes are usually enclosed behind the secondary lining and it is impossible to open the lining structure to clean the precipitation crystals, most of the existing cleaning methods are to send medicine into the drainage pipes, use the reaction between the medicine and the precipitation crystals to dissolve the precipitation crystals, and then export the medicine together with the dissolved precipitation crystals from the drainage pipes. Although the above method realizes the cleaning of the precipitation crystals, the cleaning effect is not ideal, and there are still a small amount of precipitation crystals adhering to the pipe wall.

DETAILED DESCRIPTION

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0046] Reference Figures 1-7 The present invention provides a clearing device based on karst tunnel crystallization, comprising: a mobile vehicle 1, which is arranged in a pipeline 2. The mobile vehicle 1 is a vehicle body structure that can move in the pipeline 2, and it can be a robot suitable for walking in the pipeline 2 to drive the first plugging unit 3 and the second plugging unit 4 to move in the pipeline 2.

[0047] The first plugging unit 3 is connected to the front end of the moving direction of the mobile vehicle 1, and is configured to block the inner wall of the pipe 2; the second plugging unit 4 is connected to the rear end of the moving direction of the mobile vehicle 1, the second plugging unit 4 is adapted to the inner wall of the pipe 2, the second plugging unit 4 is configured to block the pipe 2, and the second plugging unit 4 scrapes the inner wall of the pipe 2 when the mobile vehicle 1 moves along the moving direction; wherein, a medicine cavity is formed between the first plugging unit 3 and the second plugging unit 4, and the medicine cavity is filled with medicine.

[0048] Specifically, when cleaning the pipeline 2, first send the first plugging unit 3 into the pipeline 2, and then send the mobile vehicle 1 into the pipeline 2. The mobile vehicle 1 moves in the pipeline 2, driving the first plugging unit 3 and the second plugging unit 4 to move, and pre-cleaning the inlet position of the pipeline 2. When the second plugging unit 4 enters the pipeline 2, the outer wall of the second plugging unit 4 contacts the inner wall of the pipeline 2 to achieve plugging of one end of the pipeline 2, so that a medicine cavity is formed between the first plugging unit 3 and the second plugging unit 4. By sending medicine into the cavity, the medicine remains in the medicine cavity and reacts with the precipitated crystals on the inner wall of the pipeline 2. After a period of reaction, the sewage in the medicine cavity is discharged, and then the mobile vehicle 1 moves, and the second plugging unit 4 is used to scrape the precipitated crystals remaining on the inner wall of the pipeline 2, so as to achieve effective cleaning of the precipitated crystals.

[0049] In addition, when there are precipitated crystals in a part of the pipe 2, the cleaning device can be sent to a predetermined area so that the area with the precipitated crystals is located in the medicine cavity, and then the medicine cavity is filled with medicine. This setting can avoid filling the entire pipe 2 with medicine, which can reduce the consumption of medicine on the one hand and improve the cleaning efficiency on the other.

[0050] In this embodiment, refer to Figure 1 , Figure 2 , Figure 3 , and also includes; a first rod body 5, both ends of which are respectively connected to the mobile vehicle 1 and the second blocking unit 4; a high-pressure water disc 6, which is sleeved and fixed on the first rod body 5, and a plurality of water spray heads 11 are opened on the side of the high-pressure water disc 6. The water inlet end of the high-pressure water disc 6 is connected to the water inlet pipe 7, and the water inlet pipe 7 passes through the second blocking unit 4 and extends out of the pipeline 2.

[0051] Specifically, the second plugging unit 4 is connected and fixed to the mobile vehicle 1 through the first rod body 5, and a high-pressure water disc 6 is mounted on the first rod body 5. When the sewage in the medicine chamber is discharged, water can be supplied to the water inlet pipe 7, so that high-pressure water is sprayed from the water spray head 11 on the high-pressure water disc 6 to the inner wall of the pipe 2. The inner wall of the pipe 2 is firstly high-pressure flushed by the high-pressure water, and then the inner wall of the pipe 2 is scraped and cleaned by the second plugging unit 4, thereby further improving the effect of removing the precipitated crystals on the inner wall of the pipe 2.

[0052] In this embodiment, refer to Figure 1, Figure 2 , Figure 3 The water inlet pipe 7 has a clean water supply state and a chemical water supply state. In the clean water supply state, the high-pressure water pan 6 is connected to the clean water supply box through the water inlet pipe 7. In the chemical water supply state, the high-pressure water pan 6 is connected to the chemical water supply box through the water inlet pipe 7.

[0053] Specifically, the water inlet pipe 7 can be used to supply clean water or medicine. At the initial stage of cleaning, medicine is fed into the water inlet pipe 7, and the medicine is sprayed into the medicine cavity by the high-pressure water disc 6. The medicine fills the medicine cavity and is in full contact with the inner wall of the pipe 2. After a period of time, the sewage in the medicine cavity is discharged, and clean water is fed into the water inlet pipe 7. During the process of feeding clean water, the mobile vehicle moves, driving the high-pressure water disc 6 to move along the inner wall of the pipe 2, thereby flushing the inner wall of the pipe 2 and scraping the inner wall of the pipe 2 by the second plugging unit 4.

[0054] In this embodiment, refer to Figure 4 , Figure 5 , Figure 6 The first blocking unit 3 includes: a center plate 301, which is fixed to the mobile vehicle 1 through the second rod body 8; a stacking plate group, which is configured to block the inner wall of the pipe 2 and is connected to the center plate 301 through an elastic member; a retracting member, which is fixed to one end of the center plate 301 away from the second rod body 8, and the telescopic end of the retracting member is connected to the stacking plate group, so that the stacking plate group is retracted away from the inner wall of the pipe 2.

[0055] Specifically, in actual application, since there is precipitated crystals on the inner wall of the pipe 2, the outer wall of the first sealing unit 3 cannot fit with the inner wall of the pipe 2, resulting in poor sealing of the medicine chamber. Therefore, a stacked plate group is connected to the center plate 301 through an elastic member, and the stacked plate group is expanded and contacts with the precipitated crystals under the action of the elastic member. When the medicine chamber is filled with medicine, the medicine flows out from the gap between the stacked plate group and the inner wall of the pipe 2, and dissolves the precipitated crystals in the area during the outflow process, so that the stacked plate group continues to expand until it fits with the inner wall of the pipe 2, thereby achieving sealing of the inner wall of the pipe 2. In this process, since the second sealing unit 4 is always in contact and fit with the inner wall of the pipe 2, there is no need to consider the existence of a gap between the second sealing unit 4 and the pipe 2 under the action of the precipitated crystals.

[0056] At the same time, during the movement of the mobile vehicle 1, the unfolded stacking plate group is easily blocked by hard precipitated crystals, which affects the movement of the mobile vehicle 1. Therefore, a retracting member is provided on the center plate 301. During the movement of the mobile vehicle 1, the retracting member works to retract the stacking plate group, reducing the cross-sectional area of ​​the stacking plate group to achieve normal movement of the mobile vehicle 1.

[0057] In this embodiment, refer to Figure 5The stacked plate group includes: a first arc plate group, including a plurality of first arc plates 302 circumferentially connected to the center plate 301, and the first arc plates 302 are slidably matched with the center plate 301 through elastic members; a second arc plate group, which is arranged on a side of the first arc plate group away from the center plate 301 and is staggered with the first arc plate group, and the second arc plate group includes a plurality of second arc plates 303 circumferentially connected to the center plate 301, and the second arc plates 303 are slidably matched with the center plate 301 through elastic members, and the second arc plates 303 are configured to block the gap between two adjacent first arc plates 302.

[0058] Specifically, multiple first curved plates 302 are located on the same vertical plane, multiple second curved plates 303 are on the same vertical plane, and the second curved plates 303 are used to block the gap between two adjacent first curved plates 302. At the same time, each first curved plate 302 and each second curved plate 303 are respectively connected to the center plate 301 through an elastic member, so that each first curved plate 302 and each second curved plate 303 can move independently. Even if there are precipitated crystals on the inner wall of the pipeline 2, the cooperation of multiple first curved plates 302 and multiple second curved plates 303 can still achieve large-area blocking of the pipeline 2.

[0059] The outer wall surfaces of the first arc plate 302 and the second arc plate 303 are arc-shaped structures so as to better fit with the inner wall of the pipe 2 .

[0060] In this embodiment, refer to Figure 6 A plurality of grooves 304 are provided on the end surface of the center plate 301 away from the second rod body 8, and the elastic member includes: a limiting rod 305, fixed in the groove 304; a slider 306, sleeved on the limiting rod 305, and arranged in the groove 304 to slide with the center plate 301, one end of the plurality of sliders 306 are respectively fixed to the first arc plate 302 and the second arc plate 303; a compression spring 307, sleeved on the limiting rod 305, and the two ends are respectively fixed to the slider 306 and the inner wall of the groove 304.

[0061] Specifically, the limit rod 305 is used to limit the slider 306 so that the slider 306 drives the first curved plate 302 and the second curved plate 303 to move only along the extension direction of the groove 304. A compression spring 307 is sleeved on the limit rod 305. Under the action of the compression spring 307, the first curved plate 302 and the second curved plate 303 have a tendency to move toward the inner wall of the pipe 2.

[0062] Since the first curved plate 302 and the second curved plate 303 are not located on the same vertical plane, the slider 306 for connecting the second curved plate 303 is relatively long. The slider 306 passes through the gap between two adjacent first curved plates 302 and is connected and fixed to the second curved plate 303 .

[0063] In this embodiment, refer to Figure 5 , Figure 6 The retracting and pulling member includes: a sleeve 308, fixed on the center plate 301; a telescopic cylinder 309, fixed in the sleeve 308, and a connecting rope 310 is fixed to one end of the first arc plate 302 and the second arc plate 303 away from the inner wall of the pipe 2, and the other end of the connecting rope 310 passes through the sleeve 308 and is connected to the telescopic end of the telescopic cylinder 309.

[0064] Specifically, when the movable end of the telescopic cylinder 309 is extended, the connecting rope 310 is relaxed, and the first arc plate 302 and the second arc plate 303 are unfolded under the action of the compression spring 307. When the mobile vehicle 1 moves, the movable end of the telescopic cylinder 309 is contracted, so that the connecting rope 310 is tightened, and the first arc plate 302 and the second arc plate 303 are pulled by the connecting rope 310 and retracted.

[0065] In this embodiment, refer to Figure 4 , Figure 5 , Figure 6 , and also includes an annular airbag 9, which is sleeved and fixed on the outer wall of the first blocking unit 3. The annular airbag 9 is connected to the air supply pipe 10, and the annular airbag 9 is configured to be inflated to block the inner wall of the pipeline 2.

[0066] Specifically, on the basis of the cooperation between the first arc plate 302 and the second arc plate 303 to seal the inner wall of the pipe 2, in order to further improve the sealing effect, an annular airbag 9 is fixed on the outer wall of the center plate 301. When the first arc plate 302 and the second arc plate 303 contact the inner wall of the pipe 2, the air supply pipe 10 is inflated, so that the annular airbag 9 swells and adheres to the inner wall of the pipe 2, thereby further improving the sealing effect of the medicine cavity.

[0067] In addition, since the annular airbag 9 is located on the side of the first arc plate 302 close to the mobile vehicle 1, when the annular airbag 9 is inflated, the first arc plate 302 can be used as a supporting structure of the annular airbag 9, and even if the pressure in the medicine cavity is relatively high, the effective sealing of the annular airbag 9 can still be guaranteed.

[0068] In this embodiment, refer to Figure 3 The second blocking unit 4 includes: a blocking scraper 401, the outer wall of which is arranged on the inner wall of the pipe 2, and the blocking scraper 401 is detachably connected to the first rod body 5; a sewage pipe 402, which is fixedly connected to the bottom of the blocking scraper 401 and is configured to discharge sewage.

[0069] Specifically, the outer wall of the plugging scraper 401 is in contact with the inner wall of the pipe 2. When the liquid medicine is filled into the liquid medicine cavity, the plugging scraper 401 blocks the pipe 2. When the mobile vehicle 1 moves, the plugging scraper 401 scrapes the inner wall of the pipe 2. Impurities dropped by scraping are mixed with water and discharged through the sewage pipe 402.

[0070] Furthermore, a mounting sleeve 403 is fixed on the end surface of the blocking scraper 401 close to the first rod body 5, and the mounting sleeve 403 is threadedly connected to the first rod body 5, so that the shape and size of the blocking scraper 401 can be replaced according to the shape and size of the inner wall of the pipeline 2.

[0071] Reference Figure 7 , based on the removal method of karst tunnel crystallization, the operation steps include:

[0072] S1, send the moving vehicle 1 into the pipeline, clean the entrance position of the pipeline 2, and then send the center plate 301, the moving vehicle 1, and the blocking scraper 401 into the pipeline 2 in sequence.

[0073] S2, after the mobile vehicle 1 is in place, the first blocking unit 3 is deployed. When the mobile vehicle 1 reaches the preset position, the movable end of the telescopic cylinder 309 is activated to extend the movable end of the telescopic cylinder 309, the connecting rope 310 is relaxed, and the first arc plate 302 and the second arc plate 303 are deployed under the action of the compression spring 307 and contact the precipitated crystals on the inner wall of the pipe 2.

[0074] S3, injecting medicine into the medicine cavity, the medicine passes through the gap between the first plugging unit 3 and the inner wall of the pipeline 2, and dissolves the precipitated crystals in the gap area, so that the first plugging unit 3 continues to expand and contacts the inner wall of the pipeline 2 to plug the pipeline 2.

[0075] Specifically, medicine is fed into the medicine cavity through the water inlet pipe 7, and the medicine passes through the gap between the first curved plate 302, the second curved plate 303 and the inner wall of the pipe 2, and dissolves the precipitated crystals in the gap area. After a period of time, the first curved plate 302 and the second curved plate 303 contact the inner wall of the pipe 2, and air is supplied to the air supply pipe 10 to drive the annular airbag 9 to bulge, and then the medicine cavity continues to be filled with medicine, so that the pressure in the medicine cavity reaches a preset value.

[0076] S4, after the liquid medicine cavity is filled with liquid medicine for a predetermined reaction time, the sewage in the liquid medicine cavity is discharged and the first plugging unit 3 is recovered.

[0077] Specifically, after the medicine remains in the medicine chamber for a period of time, the sewage is discharged through the sewage pipe 402, and then the movable end of the telescopic cylinder 309 is started to shrink the movable end of the telescopic cylinder 309, and the connecting rope 310 is tightened to drive the first curved plate 302 and the second curved plate 303 to retract.

[0078] S4 , the moving vehicle 1 moves so that the second plugging unit 4 scrapes the inner wall of the pipeline 2 .

[0079] Specifically, the mobile vehicle 1 continues to move, and clean water is delivered to the water inlet pipe 7 during the movement. The clean water is sprayed out by the high-pressure water tray 6 to clean the inner wall of the pipe 2. At the same time, the blocking scraper 401 scrapes the inner wall of the pipe 2 during the movement. After the mobile vehicle 1 moves a certain distance, steps S2 to S4 are repeated.

[0080] The above are only preferred specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
