[0002] Pipeline dredging technology As urbanization progresses, if pipelines are not cleaned for a long time, a large amount of sludge will adhere to their walls, causing serious siltation in the pipelines, slowing down the flow rate, reducing their drainage capacity, and increasing the risk of urban waterlogging. Municipal dredging not only helps flood control and drainage, but also improves the living environment of surrounding citizens. When pipelines are silted, they are prone to breeding bacteria, pests and aquatic harmful organisms. Dredging can remove the silted dirt and waste to ensure healthy water quality.

[0003] After some small vertical pipes are clogged for a long time, a large amount of dirt is easily attached to the pipe wall, slowing down the flow rate of the pipeline. After the cleaning operation, large pieces of sticky silt fall to the bottom of the pipe, which easily leads to secondary blockage of the pipeline. The cleaning is relatively complicated and difficult. Therefore, a pipeline cleaning device for dredging engineering is proposed here to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1-4 As shown, the utility model provides a pipeline cleaning device for dredging engineering, including an airbag component 1 and an inflation component, wherein a plurality of support components are evenly distributed on the surface of the airbag component 1 along its circumference; the support component includes a plurality of support members 6 and a cushion block 9 arranged along the circumference of the airbag component 1, wherein the support member 6 is rotatably connected to the airbag component 1, and when the support member 6 is rotated to a final state, the central axis of the support member 6 is perpendicular to the docking member 4, and the top end of the cushion block 9 is in contact with the lower end of the support member 6.

[0026] In this embodiment, the support member 6 has different surface morphologies, for example:

[0027] When the support member 6 is in use, the central axis of the support member 6 may not be perpendicular to the docking member 4, and the central axis of the support member 6 may be parallel to or cross the docking member 4. Figure 2 As shown, at this time, the outer end of the support member 6 can be rotated toward the airbag member 1 and is in a folded state.

[0028] When the support member 6 is in use, the central axis of the support member 6 is perpendicular to the docking member 4. Figure 1 As shown, at this time, the outer end of the support member 6 rotates toward the cushion block 9 until it is in contact with the top end surface of the cushion block 9.

[0029] Since the support member 6 is rotatably connected to the airbag member 1, during the process of the airbag member 1 entering the construction pipeline, the airbag member 1 is in a contracted state, and the support member 6 can also be retracted to one side of the airbag member 1, and the overall volume is reduced, thereby facilitating the entire device to enter the interior of the construction pipeline. During the process of the air pump supplying air to the airbag member 1, the airbag member 1 continues to expand. At this time, the support member 6 can be rotated to fit with the top of the cushion block 9, and the cushion block 9 acts as a barrier, so that multiple support members 6 are matched around the airbag member 1 in a tray shape. Mud blocks that fall off during the construction process can fall on its surface, and the lifting device as a whole can bring out the mud blocks, without the need for manual entry into the pipeline for cleaning, thereby reducing labor costs and manpower consumption.

[0030] The airbag component 1 can be made of synthetic rubber or natural rubber and a fiber reinforcement layer after vulcanization. It has good anti-expansion strength, elasticity and flexibility. The rubber airbag component 1 can be used in construction under various working conditions.

[0031] In some embodiments, the inflatable assembly includes an operating pipe 2 installed at one end of the surface of the airbag component 1. A counterweight ring is threadedly provided at the connection between the operating pipe 2 and the airbag component 1. The weight of the airbag component 1 is increased by the counterweight ring to accelerate the descending speed of the device placed in the vertical pipe. The other end of the operating pipe 2 is fixedly connected to a handle 201. The cross-section of the handle 201 is an elliptical frame. The elliptical frame fits the shape of the human hand better, which is convenient for the operator to grasp the handle 201 to pull the operating pipe 2, thereby taking out the airbag component 1 faster and taking out the mud generated during the construction process. In other embodiments, the handle 201 can also be a rectangular frame, a circular frame, or any other shape that is convenient for grasping. This embodiment of the present application is only taken as an example and is not limited to this.

[0032] In this embodiment, an air intake pipe 3 connected to the airbag component 1 is inserted inside the operating pipe 2, and an air pump is externally connected to the other end of the air intake pipe 3, and the air intake pipe 3 is connected to the output port of the air pump.

[0033] The air pump is a device for removing air from a closed space or adding air to a closed space. When selecting an air pump, an electric-powered air pump can be selected, which continuously compresses air through electricity to generate air pressure to supply air to the airbag 1.

[0034] In some embodiments, the surface of the airbag component 1 is integrally formed with a connector 101 , which has a certain thickness and a rectangular cross-section; the support assembly also includes a docking component 4 , which fits with the connector 101 and is fixedly sleeved on the surface of the connector 101 .

[0035] In other embodiments, the surface of the airbag component 1 is integrally formed with a connector 101 , and the cross-section of the connector 101 can be of any shape; the support assembly also includes a docking component 4 , and the docking component 4 can be of any shape structure that can match the connector 101 .

[0036] The embodiments of the present application are only taken as an example and are not limited to this.

[0037] In this embodiment, a torsion spring 401 is provided between the support member 6 and the docking member 4 , wherein a spring shaft on one side of the torsion spring 401 is fixedly connected to the docking member 4 , and a spring shaft on the other side is movably connected to the surface of the support member 6 .

[0038] In this embodiment, the torsion spring 401 has different forms, for example:

[0039] In this embodiment, when the torsion spring 401 is in the initial state, Figure 1 and 3 As shown, the spring axis on one side of the torsion spring 401 is fixedly connected to the docking member 4, and the spring axis on the other side is movably connected to the surface of the support member 6. The torsion axes on both sides are perpendicular to each other, and the torsion spring 401 does not generate torque or rotational force.

[0040] When the torsion spring 401 is in a stressed state, Figure 2 As shown, the spring shaft on one side of the torsion spring 401 is fixedly connected to the docking member 4, and the spring shaft on the other side is movably connected to the surface of the support member 6. The torsion shafts on both sides approach each other due to the torque or rotational force generated by the torsion spring 401.

[0041] When the support assembly enters the construction pipeline and contacts the pipeline wall and is subjected to force, the support member 6 rotates upward and squeezes the torsion spring 401. The support member 6 rotates around the center of the torsion circle of the torsion spring 401. After the external force disappears, the torsion spring 401 releases its internal elastic energy and drives the support member 6 to rotate back to the initial state through the torsion axis. At this time, the central axis of the support member 6 is perpendicular to the docking member 4, and the top of the cushion block 9 is in contact with the lower end of the support member 6.

[0042] In some embodiments, a positioning frame 5 for installing the support member 6 is fixedly connected to the side of the surface of the docking member 4 close to the support member 6, and the fixing method is a threaded connection. Thread grooves are reserved at the relative positions of the docking member 4 and the positioning frame 5. Screws that fit the thread grooves are threadedly connected and pass through the positioning frame 5, and are threadedly fixed to the docking member 4. The support member 6 is rotatably connected to the positioning frame 5 through a fixing rod.

[0043] In other embodiments, a positioning frame 5 for installing the support member 6 is fixedly connected to the side of the surface of the docking member 4 close to the support member 6. The fixing method is gluing. The position where the docking member 4 and the positioning frame 5 are connected is coated with glue. The glue can be industrial glue such as acrylic adhesive, anaerobic glue or instant glue. Industrial glue has the characteristics of high strength, high applicable temperature, and a wide range of viscosity options. The support member 6 is rotatably connected to the positioning frame 5 through a fixing rod.

[0044] In some embodiments, Figure 1 and 3 As shown, the support member 6 includes a bottom plate portion 601 rotatably connected to the positioning frame 5 and a side plate portion 602 fixedly connected to the bottom plate portion 601. The side plate portion 602 is tilted upward, which can keep the support member 6 as large as possible in area for holding mud blocks while providing a certain degree of blocking effect on the mud blocks therein to prevent them from falling out. In other embodiments, the side plate portion 602 can be arranged upward, and the side plate portion 602 is arranged vertically relative to the bottom plate portion 601. In still other embodiments, the side plate portion 602 and the bottom plate portion 601 are arranged in an integrated manner.

[0045] The side plate portion 602 of the support member 6 is fixedly connected to a mounting frame 7, the mounting frame 7 is fixedly connected to the outside of the side plate portion 602, and the inside of the mounting frame 7 is movably connected to an auxiliary wheel 8 via a rotating shaft. In some embodiments, the rotating shaft is fixedly connected to the mounting frame 7, and the auxiliary wheel 8 is rotatably connected to the rotating shaft; in other embodiments, the rotating shaft is rotatably connected to the mounting frame 7, and the auxiliary wheel 8 is fixedly connected to the rotating shaft. During the process of lifting the airbag member 1, the auxiliary wheel 8 is always in contact with the wall of the construction pipeline, the auxiliary device moves as a whole, and the support assembly does not contact the pipe wall, so as to avoid the loss of the support assembly caused by friction.

[0046] In some embodiments, Figure 1 and 2 As shown, the cross-section of the cushion block 9 is triangular, and the hypotenuse of the triangle is downward, and the two adjacent right-angled sides are respectively in contact with the surface of the docking member 4 and the bottom of the positioning frame 5, which saves materials and increases the stability and supporting force of the triangle. In other embodiments, the cross-section of the cushion block 9 may also be rectangular.

[0047] The working principle of this specific implementation is:

[0048] After some small vertical pipes are clogged for a long time, a lot of dirt adheres to the pipe wall, and the flow rate of the pipe slows down. Before the desilting operation, the handle 201 is held and the airbag 1 is placed into the vertical pipe. At this time, the airbag 1 is in a contracted state and falls rapidly in the pipe due to the weight of the counterweight. When the airbag 1 falls, the support assembly enters the construction pipe and contacts the pipe wall, and the support 6 rotates upward and squeezes the torsion spring 401. The support 6 rotates around the center of the torsion circle of the torsion spring 401 and rotates upward to approach the airbag 1, and the volume is reduced. During the process of supplying air to the airbag component 1, the airbag component 1 continues to expand. At this time, the external force disappears, and the torsion spring 401 releases its internal elastic energy to drive the support component 6 to rotate back to the initial state through the torsion axis. The support component 6 rotates to fit with the top of the cushion block 9. Multiple support components 6 are matched around the airbag component 1 in a tray shape, and construction operations can be carried out. During the construction process, mud blocks falling from the pipe wall fall onto the support component 6 and the top of the airbag component 1. After the construction is completed, pull the handle component 201, and the mud blocks are taken out as a whole through the handle component lifting device to complete the use.

[0049] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
