TECHNICAL FIELD

[0001] The present application belongs to the technical field of pipeline cleaning equipment, and particularly relates to a tunnel drainage blind pipe cleaning device. BACKGROUND

[0002] The drainage blind pipe is also called drainage blind ditch, which is mainly made of synthetic fibers, plastics and synthetic rubber, and is made into various types and multifunctional geotechnical products through different process methods. The plastic blind ditch is usually composed of a filter membrane made of corrosion-resistant fibers and a three-dimensional network of modified polyethylene, both of which have the advantages of never degrading in soil and water, and maintaining the characteristics of the material unchanged. The material is hydrophobic, has small resistance, has extremely high surface water permeability and internal water permeability, and has excellent compression resistance and deformation adaptability. It has excellent chemical inertness and can maintain long service life in geotechnological engineering. It is light in weight, easy to cut, and convenient to install and construct.

[0004] The drainage blind pipe is commonly used for draining water in the mountain in tunnel construction to ensure dryness inside the tunnel and reduce seepage deformation. The drainage blind pipe is usually coated with a water barrier film layer to isolate impurities outside the blind pipe. However, with the penetration of water flow, crystalline bodies and sludge are easily formed in the pipe. After a long period of accumulation, the drainage diameter of the drainage blind pipe is continuously reduced, resulting in a decrease in the water conducting performance of the pipe. Due to the particularity of the blind pipe structure, the wheel structure of the conventional pipeline cleaning equipment is prone to slipping in the pipeline, causing the equipment to slip or get stuck.

[0026] In order to more clearly illustrate the structural features and effects of the present application, the present application will be described in detail below in combination with the drawings and specific embodiments.

[0027] Please refer to Figures 1-5The tunnel drainage blind pipe cleaning device in one embodiment of the application comprises a shell member 1, the shell member 1 comprises a main shell 101, a dirty inlet 102, a dirty outlet 103, a rotating groove 104 and a rotating body 105, the main shell 101 is provided with the dirty inlet 102 at one end, the dirty inlet 102 is used for collecting dirty impurities in the drainage blind pipe, the main shell 101 is provided with the dirty outlet 103 at the other end, the dirty outlet 103 is used for discharging dirty impurities filtered by the main shell 101, a plurality of rotating grooves 104 are arranged on the wall surface of the main shell 101, the rotating body 105 is rotatably arranged in the rotating groove 104, and a sliding groove 106 is arranged in the rotating body 105; a collection cover assembly 2 comprises a conical cover 201, a rotating shaft 202 and a flow guide pipe 203, the conical cover 201 is arranged on one side of the dirty inlet 102 and is rotatably connected to one end of the dirty inlet 102 through the rotating shaft 202, the conical cover 201 and the rotating shaft 202 are further provided with the flow guide pipe 203 in the middle part, and the flow guide pipe 203 is in communication with the main shell 101; a rocker arm assembly 3 comprises a driving disc 301, a short rod 302 and a long rod 303, a plurality of driving discs 301 are arrayed in the main shell 101, the short rod 302 is rotatably arranged on the driving disc 301, the long rod 303 is rotatably arranged at the end of the short rod 302, the long rod 303 is slidably arranged in the sliding groove 106, and a plurality of driving discs 301 are connected in linkage; a filter pressing mechanism 4 is movably arranged in the main shell 101 and connected in linkage with the rocker arm assembly 3, used for reciprocatingly extruding dirty impurities to filter water in the impurities; and a collection bag 5 is fixedly sleeved on one side of the dirty outlet 103, used for recycling filtered impurities; a plurality of driving discs 301 are arranged in two groups in the upper layer and the lower layer of the main shell 101, and the driving discs 301, the short rods 302 and the long rods 303 in the upper layer and the lower layer are mirror image arranged.

[0028] In actual application, when the cleaning device is used to treat the dirt and impurities in the blind drain pipe, first, the tapered cover 201 at one end of the device is inserted into one end of the blind drain pipe, and the main shell 101 is placed into the blind drain pipe as a whole. At this time, a plurality of drive discs 301 inside the main shell 101 can be driven by the motor to rotate synchronously. The rotation directions of the drive discs 301 in the upper layer and the lower layer of the main shell 101 are opposite. The plurality of drive discs 301 in the upper layer of the main shell 101 rotate counterclockwise, and the plurality of drive discs 301 in the lower layer of the main shell 101 rotate clockwise. The plurality of drive discs 301 can drive the short rod 302 to rotate counterclockwise in the rotating process. Since one end of the long rod 303 is connected with the short rod 302 to rotate, and the other end is slidably assembled in the sliding groove 106, the end of the long rod 303 can be quickly slid out of the sliding groove 106 when the short rod 302 rotates towards the rotating body 105, and the end of the long rod 303 can be inserted into the limiting gap of the blind drain pipe. When the short rod 302 rotates to the point near the rotating body 105 and gradually moves away from the rotating body 105, the distance between the short rod 302 and the rotating body 105 is reduced, so that the end of the long rod 303 moves away from one side of the main shell 101. With the rotation of the rotating body 105, the rotation angle of the rotating body 105 matches the extension length of the long rod 303, so that the end of the long rod 303 moves in an arc and exerts force on the inner wall of the blind drain pipe, thereby reacting on the main shell 101. The main shell 101 as a whole continuously advances in the blind drain pipe, and finally moves out from the other end of the blind drain pipe. The fiber gap of the blind drain pipe is fully utilized for sliding power assistance, avoiding the problem of possible slippage of the conventional wheel type driving structure. During the movement of the main shell 101, the tapered cover 201 at one end of the main shell 101 is attached to the inner diameter of the blind drain pipe, so that the dirt and impurities in the pipe can be guided along the guide pipe 203 into the main shell 101, and the dirt and impurities can be filtered by the filter press mechanism 4. The dirt and impurities are collected by the collecting bag 5, effectively preventing the silt impurities from blocking the device and affecting the movement of the device.

[0029] In one case in the present embodiment, the device can be fixed at the end of the cable. When the device is stuck in the blind drain pipe, it can be pulled out of the blind drain pipe by pulling the cable. Since the tapered cover 201 has an inverted V-shaped structure, it will not interfere with the pulling out of the device. Here, no specific limitation is made.

[0030] Please refer to Figure 2 In a preferred embodiment of the present application, the shell member 1 further comprises a drainage hole 107, a drive motor 108 and a worm 109. The drainage holes 107 are arranged on the wall surface of the main shell 101. The drive motor 108 is arranged in the main shell 101 and connected with any one of the drive discs 301. The worm 109 is arranged in the main shell 101 and connected with any one of the drive discs 301.

[0031] In practical application, the drain hole 107 on the main shell 101 can cooperate with the water filtering function of the filter press mechanism 4 to discharge the filtrate inside the main shell 101, preventing the inside of the main shell 101 from being blocked, the driving motor 108 can drive the driving discs 301 in the upper and lower layers to rotate in different directions, and when the rotation direction of the motor is switched, the main shell 101 can be driven to move reversely, and the worm 109 is connected with any one of the driving discs 301.

[0032] Please refer to Figure 2 In a preferred embodiment of the present application, the collecting cover assembly 2 further comprises a worm gear 204 and a rounded end 205, the worm gear 204 is fixedly assembled at one end of the rotating shaft 202 and is connected with the worm 109, and the rounded end 205 is arranged at the end of the conical cover 201 and is connected with the drain blind pipe in a sliding manner.

[0033] In practical application, the worm gear 204 is fixedly assembled at one end of the rotating shaft 202 and is connected with the worm 109, the rotation of the worm 109 can drive the worm gear 204 to rotate, and the rotation of the worm gear 204 can cooperate with the continuous advancement of the main shell 101 and the continuous rotation of the conical cover 201 to rotate and break the crystal body fixed at the inner end of the drain blind pipe, the rounded end 205 at the end of the conical cover 201 can reduce the sliding resistance between the conical cover 201 and the drain blind pipe and prevent the inner wall of the drain blind pipe from being scratched.

[0034] Please refer to Figure 1 In a preferred embodiment of the present application, the diameter of the conical cover 201 is greater than the inner diameter of the drain blind pipe.

[0035] In practical application, the outer diameter of the conical cover 201 is slightly larger than the inner diameter of the drain blind pipe, and the flexibility of the drain blind pipe can make the conical cover 201 and the drain blind pipe in a sliding friction state, on the one hand, the dirt and impurities at the inner wall end of the drain blind pipe can be separated by extruding the drain blind pipe, and on the other hand, the sludge and impurities in the pipe can be effectively guided into the flow guide pipe 203 and transported into the main shell 101 for water filtering.

[0036] Please refer to Figure 1 In a preferred embodiment of the present application, the filter press mechanism 4 comprises a pressing plate 401, an elastic member 402 and a filter screen 403, two groups of the pressing plate 401 are arranged in the main shell 101 in a sliding manner and are arranged on the side of the pollution inlet 102 in parallel, the pressing plate 401 and the main shell 101 are connected in a movable manner through the elastic member 402, and the filter screen 403 is further arranged on the pressing plate 401.

[0037] In actual application, the two groups of the pressing plates 401 are slidingly assembled in the main shell 101 and arranged in the upper and lower two layers respectively, when the short rod 302 is rotated and pressed on the pressing plates 401, the pressing plates 401 can slide towards each other to overcome the elastic force of the elastic members 402, so that the dirt and impurities between the pressing plates 401 are squeezed to start filtering water, and the filtered water can flow into the drainage blind pipe through the filter screen 403 and the drainage hole 107, when the short rod 302 is rotated away from one side of the pressing plate 401, the pressing plate 401 can be reset under the elastic force of the elastic member 402, so that the gap between the two groups of pressing plates 401 is increased, so that the dirt and impurities accumulated at one end of the conical cover 201 can be conducted between the two groups of pressing plates 401 to realize the circular motion.

[0038] In one case of the embodiment, since the drainage blind pipe is usually coated with a filter membrane outside, the dirt and impurities in the blind pipe are mainly sludge and small crystals, so the problem of blocking at one end of the conical cover 201 is negligible.

[0039] Please refer to Figure 2 In a preferred embodiment of the present application, the collecting bag 5 adopts a cylindrical structure and is made of waterproof material.

[0040] In actual application, the collecting bag 5 adopts a cylindrical structure matching the diameter of the drainage blind pipe, by limiting the diameter, the excessive accumulation of impurities can be prevented from affecting the movement of the main shell 101, on the other hand, the use of waterproof material can reduce the reabsorption of impurities after filtering water, preventing the quality from being too large to affect the normal movement of the main shell 101 after secondary water absorption.
