Description

Technical Field

[0001] The present invention relates to the technical field of drainage pipe cleaning, and particularly relates to a device for removing crystal blockages in drainage pipes. Background Art

[0002] With the gradual increase in the number of tunnel engineering constructions in recent years, such as subway tunnels, mined stations, and mountain tunnels, the construction drainage and operation maintenance of underground space projects have become the key points and difficulties in the next stage of transportation infrastructure construction; as a linear structure buried below the ground surface, tunnels need to withstand the long-term action and influence of the groundwater environment during their service life. In order to ensure the durability and safety of the structure, it is usually necessary to set up drainage facilities behind the lining such as circumferential and longitudinal drainage blind pipes to divert the seepage water from the surrounding rock into the central drainage ditch; however, since groundwater often contains various soluble salts, crystal precipitation generally occurs under the complex action of the solid, liquid, and gas three-phase systems, seriously affecting the working efficiency of the tunnel drainage system and even further inducing water damage problems such as blockages in the tunnel drainage pipes. At present, the solutions for crystal blockages in tunnel drainage pipes mainly include methods such as optimizing the inner wall structure material of the drainage pipe, acoustic wave fragmentation cavitation, and acid reagent dissolution. However, in the face of the increasing demand for construction drainage and operation maintenance of tunnel projects, there are still problems such as high cost, great difficulty, low error tolerance, and invisible cleaning effect. Summary of the Invention

[0003] Aiming at the above deficiencies of the prior art, the present invention provides a device for removing crystal blockages in drainage pipes, which solves the problem of difficult cleaning of crystals in drainage pipes.

[0004] To achieve the above object, the technical solution adopted by the present invention is as follows:

[0005] Provide a device for removing crystal blockages in drainage pipes, which includes a first housing. A motor is arranged inside the first housing, and the rotating shaft of the motor is in transmission connection with a brush roller through a transmission rod. A circulation mechanism is arranged on the transmission rod. The circulation mechanism includes a guide sleeve fixedly sleeved on the transmission rod. A spiral first groove and a second groove are arranged on the outer side wall of the guide sleeve. The first groove and the second groove are staggered with each other and have opposite spiral directions. The ends of the first groove and the second groove on the same side are all communicated with each other. The radial depths of the first groove and the second groove are different. A second housing is movably sleeved on the guide sleeve. A sliding groove parallel to the extending direction of the guide sleeve is arranged on the second housing. A sliding buckle is slidably arranged on the sliding groove. A guiding rod is movably penetrated through the sliding buckle. A sliding block is arranged at the inner end of the guiding rod. The sliding block is slidably arranged in the first groove or the second groove. A spring is sleeved on the guiding rod between the sliding block and the sliding buckle. The outer end of the guiding rod protrudes out of the second housing. A plurality of orientation rollers for facilitating axial movement along the drainage pipe are arranged on both the first housing and the second housing.

[0006] The beneficial effects of adopting the above technical solution are as follows: The motor can drive the brush roller to rotate through the transmission rod, and make the outer side of the brush roller rub against the inner side wall of the drainage pipe, so as to facilitate the removal of crystal substances adhering to the inner wall of the drainage pipe; at the same time, the motor can drive the guide sleeve to rotate through the transmission rod, and make the sliding block slide alternately between the first groove and the second groove, so that the sliding buckle makes a reciprocating linear motion on the sliding groove. When the sliding block slides in the groove with a deeper radial depth, under the action of the spring, the outer end of the guide rod does not contact the inner side wall of the drainage pipe. At this time, the device of this solution remains relatively stationary with respect to the drainage pipe; when the sliding block slides in the groove with a shallower radial depth, the outer end of the guide rod extends outwards and abuts against the inner side wall of the drainage pipe. Under the torsional action of the guide sleeve, the sliding buckle slides relative to the sliding groove, so that the device of this solution moves along the extension direction of the drainage pipe, and the sliding block slides alternately between the first groove and the second groove, so as to realize the periodic movement of the device of this solution along the extension direction of the drainage pipe.

[0007] Further, the ends of the first groove and the second groove on the same side are connected to each other through a relief groove. The relief groove is arc-shaped, and the two ends of the relief groove are smoothly connected to the ends of the first groove and the second groove respectively.

[0008] The beneficial effects of adopting the above technical solution are as follows: The relief groove can smoothly connect the ends of the first groove and the second groove with different radial depths, so as to facilitate the sliding block to slide back and forth between the first groove and the second groove, so as to realize the periodic movement of the device of this solution.

[0009] Further, the first housing and the second housing are cylindrical structures with the same radial dimension, and the first housing and the second housing are coaxially arranged. A number of directional rollers are evenly arranged in the circumferential direction at both ends of the first housing and the second housing. The axis of the directional roller is perpendicular to the axis of the first housing. The directional rollers protrude from the outer side walls of the first housing and the second housing and are in rolling cooperation with the inner side wall of the drainage pipe.

[0010] The beneficial effects of adopting the above technical solution are as follows: Such a setting leaves a certain gap between the first housing and the second housing and the inner side wall of the drainage pipe, so that the drainage of the drainage pipe will not be affected when this solution is used for cleaning; the setting of the directional rollers facilitates the movement of the device of this solution along the extension direction of the drainage pipe, and effectively prevents the first housing and the second housing from rotating relative to the drainage pipe in the circumferential direction.

[0011] Further, a contact head is arranged at the outer end of the guide rod.

[0012] Further, both the abutting head and the directional roller are made of elastic rubber, which is beneficial to improving the friction between the abutting head and the directional roller and the inner side wall of the drainage pipe. At the same time, flexible contact is adopted to avoid the expansion deformation and damage of the drainage pipe.

[0013] Further, the outer side surface of the brush roller is a flexible and rough brush surface, which makes the brush roller have good toughness to prevent the brush roller from wearing the inner wall of the drainage pipe.

[0014] Further, a storage battery for supplying energy to the motor is arranged in the first housing.

[0015] The beneficial effects of the present invention are as follows:

[0016] The structure of this solution is ingeniously designed. During specific implementation, only the construction operation and maintenance section for starting and receiving the device of this solution needs to be reserved, and then the motor is turned on. The cleaning and maintenance work of the inner wall of the drainage pipe maintenance section can be automatically realized without manual operation, and its operation is simple, economical and efficient. At the same time, the structure of this solution is simple, easy to produce and manufacture, low in cost, and economical and practical. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The following describes the specific embodiments of the present invention to facilitate the understanding of those skilled in the art of this technology. However, it should be clear that the present invention is not limited to the scope of the specific embodiments. For those of ordinary skill in the art of this technology, as long as various changes are within the spirit and scope of the present invention defined and determined by the appended claims, these changes are obvious, and all inventions and creations using the concept of the present invention are within the scope of protection.

[0024] As Figures 1 to 5 shown, the device for clearing the crystallization blockage of the drainage pipe in this solution includes a first cylindrical housing 1. Inside the first housing 1, there is a motor 11 and a storage battery 12 for supplying energy to the motor 11. The rotating shaft of the motor 11 is drivingly connected to a brush roller 3 through a transmission rod 2, so that the motor 11 can drive the brush roller 3 to rotate, and the outer side surface of the brush roller 3 generates friction with the inner side wall of the drainage pipe, so as to facilitate the removal of the crystalline substances attached to the inner wall of the drainage pipe; the outer side surface of the brush roller 3 is a flexible rough brush surface; so that the brush roller 3 has good toughness to prevent the brush roller 3 from wearing the inner wall of the drainage pipe.

[0025] A circulation mechanism is arranged on the transmission rod 2. The circulation mechanism includes a guide sleeve 41 fixedly sleeved on the transmission rod 2. A spiral first groove 42 and a second groove 43 are arranged on the outer side wall of the guide sleeve 41. The first groove 42 and the second groove 43 are staggered with each other and have opposite spiral directions. The radial depths of the first groove 42 and the second groove 43 are different. The ends of the first groove 42 and the second groove 43 on the same side are communicated with each other through a relief groove 44. The relief groove 44 is arc-shaped, and the bottom and both side walls at both ends of the relief groove 44 are smoothly connected to the bottom and both side walls of the ends of the first groove 42 and the second groove 43 respectively.

[0026] A cylindrical second housing 5 is movably sleeved on the guide sleeve 41, so that relative rotation can occur between the second housing 5 and the guide sleeve 41. A sliding groove 51 parallel to the extending direction of the guide sleeve 41 is arranged on the second housing 5. A sliding buckle 52 is slidably arranged on the sliding groove 51. A guiding rod 53 is movably penetrated through the sliding buckle 52. A sliding block 54 is arranged at the inner end of the guiding rod 53. The sliding block 54 is slidably arranged in the first groove 42 or the second groove 43. A spring 55 is sleeved on the guiding rod 53 between the sliding block 54 and the sliding buckle 52. The outer end of the guiding rod 53 protrudes from the second housing 5, and a contact head 56 is arranged at the outer end of the guiding rod 53.

[0027] The radial dimensions of the first housing 1 and the second housing 5 are the same, and the first housing 1 and the second housing 5 are coaxially arranged. Four orienting rollers 6 are evenly arranged in the circumferential direction at both ends of the first housing 1 and the second housing 5. The axis of the orienting roller 6 is perpendicular to the axis of the first housing 1 and the second housing 5. The orienting roller 6 protrudes from the outer side walls of the first housing 1 and the second housing 5 and rolls in cooperation with the inner side wall of the drainage pipe; such a setting leaves a certain gap between the first housing 1 and the second housing 5 and the inner side wall of the drainage pipe, so that the drainage of the drainage pipe will not be affected when the present solution is being cleaned; and the setting of the orienting roller 6 facilitates the movement of the device of the present solution along the extension direction of the drainage pipe, and effectively prevents the first housing 1 and the second housing 5 from rotating relative to the drainage pipe in the circumferential direction.

[0028] Preferably, both the abutting head 56 and the orienting roller 6 are made of elastic rubber; this is beneficial to increasing the friction force between the abutting head 56 and the orienting roller 6 and the inner side wall of the drainage pipe, and at the same time, flexible contact is adopted to avoid causing expansion deformation and damage to the drainage pipe.

[0029] The working principle of the present solution will be specifically described below:

[0030] The present solution can be moved along the extension direction of the drainage pipe through a circulating mechanism. Among them, the motor 11 can drive the guide sleeve 41 to rotate through the transmission rod 2, and drive the sliding block 54 to slide in the first groove 42 or the second groove 43, thereby driving the sliding buckle 52 to slide on the sliding groove 51. The first groove 42 and the second groove 43 have opposite helix directions and the ends on the same side are interconnected through a relief groove 44, so that the sliding block 54 can slide alternately between the first groove 42 and the second groove 43, and the sliding buckle 52 makes a reciprocating linear motion on the sliding groove 51; when the sliding block 54 slides in the groove with a deeper radial depth, under the action of the spring 55, the outer end of the guide rod 53 does not contact the inner side wall of the drainage pipe. At this time, the device of the present solution remains relatively stationary with respect to the drainage pipe, and the brush roller 3 cleans the inner side wall of the drainage pipe; when the sliding block 54 slides in the groove with a shallower radial depth, the outer end of the guide rod 53 extends outwards and abuts against the inner side wall of the drainage pipe, so that the guide rod 53, the sliding buckle 52 and the sliding block 54 remain relatively stationary with respect to the drainage pipe. Under the torsional action of the guide sleeve 41, the sliding buckle 52 slides relative to the sliding groove 51, so that the device of the present solution moves along the extension direction of the drainage pipe, and the sliding block 54 slides alternately between the first groove 42 and the second groove 43, thereby realizing the periodic movement of the device of the present solution.

[0031] In particular, the first housing 1, the second housing 5, the transmission rod 2, the guide sleeve 41, the guide rod 53, the spring 55, the slider 54, the sliding buckle 52, the rotating shaft and the housing of the motor 11, and the housing of the storage battery 12 of this solution all adopt waterproof alloy materials, surface anodization treatment or surface plating methods to improve the waterproof performance of each component, prevent the corrosion and damage of this solution due to being in a water-rich environment for a long time, and extend the service life of this solution.
