Description

Technical Field

[0001] This utility model relates to the field of pipeline repair technology, and in particular to a repair device for irregularly shaped pipelines. Background Technology

[0002] Irregularly shaped pipes refer to pipes with non-standard circular cross-sections (such as rectangular, elliptical, corrugated, T-shaped, Y-shaped, etc.), commonly used in municipal drainage, industrial ventilation, and chemical transportation. When leaks occur in irregularly shaped pipes exposed to corrosive media, repair devices are needed to repair the leaks. Existing repair methods involve spraying epoxy resin or polyurea coatings onto the leak area to form a new, corrosion-resistant, and wear-resistant inner wall, thus repairing the irregularly shaped pipes.

[0003] Existing irregular pipe repair devices have the following shortcomings: the spray head for applying repair coating is mostly fixed, making it inconvenient to adjust the spray position in real time. This means that the angle of the entire repair device needs to be adjusted in advance each time a leak in an irregular pipe is repaired so that the spray head is aimed at the leak, which is cumbersome and results in poor repair effect.

[0004] Therefore, those skilled in the art have proposed a device for repairing irregularly shaped pipes to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] In view of the above-mentioned irregular pipe repair device, this utility model is proposed.

[0007] Therefore, the purpose of this utility model is to provide a device for repairing irregularly shaped pipes, which solves the problem that the spray head on the device is not easy to adjust the spray angle.

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a device for repairing irregularly shaped pipes, comprising:

[0009] The main body is equipped with a storage cylinder for storing repair coating for irregular pipes. Three sets of brackets are installed at both ends of the main body. Each set of brackets has a telescopic rod slidably connected inside, and the telescopic rod is equipped with rollers.

[0010] A rotating assembly includes a circular sleeve disposed on a storage cylinder, an arc-shaped movable box rotatably disposed on the circular sleeve, and a spray head and a camera communicating with the storage cylinder mounted on the arc-shaped movable box.

[0011] In a preferred embodiment of the irregular pipe repair device of this utility model, a material pump is fixedly connected to the storage cylinder, the inlet of the material pump is connected to a material inlet pipe, and the end of the material inlet pipe away from the material pump is connected to the storage cylinder.

[0012] As a preferred embodiment of the irregular pipe repair device of this utility model, the discharge port of the material pump is equipped with a conveying pipe, and the end of the conveying pipe away from the material pump is connected to the spray head.

[0013] As a preferred embodiment of the irregular pipe repair device of this utility model, the telescopic rod is provided with multiple sets of positioning holes, and the bracket is threaded with locking screws that are connected to the positioning holes.

[0014] In a preferred embodiment of the irregular pipe repair device of this utility model, the rotating component further includes multiple sets of meshing grooves formed on the circular sleeve, and the opening end of the arc-shaped moving box is directly opposite the meshing groove.

[0015] In a preferred embodiment of the irregular pipe repair device of this utility model, a motor is fixedly connected to the arc-shaped moving box, and the output end of the motor is connected to a gear through a rotating shaft, and the gear is engaged with a meshing groove.

[0016] As a preferred embodiment of the irregular pipe repair device of this utility model, the circular sleeve is provided with a circular groove, an arc-shaped block is rotatably arranged in the circular groove, a connecting rod is fixedly connected to the outer wall of the arc-shaped block, and the end of the connecting rod away from the arc-shaped block is fixedly connected to the arc-shaped moving box.

[0017] In a preferred embodiment of the irregular pipe repair device of this utility model, a feeding pipe is installed on the storage cylinder and a cap is threadedly connected to the feeding pipe.

[0018] The beneficial effects of this utility model are as follows: The operation of the motor on the rotating component drives the gear to rotate. Since the gear is engaged with the meshing groove, and the arc-shaped moving box is limited by the connecting rod, the arc-shaped block and the circular groove, the arc-shaped moving box drives the spray head to make a circular motion, so that it is aligned with the leakage point of the irregular pipe. The material pump sprays the pipe repair paint in the storage cylinder to the leakage point of the irregular pipe, which improves the repair efficiency of the irregular pipe. By sliding the telescopic rod in the bracket and connecting the locking screw with the corresponding positioning hole, the position of the roller can be adjusted, which makes it easy for the main body to move smoothly into the interior of the irregular pipe.

[0029] Example 1

[0030] Reference Figure 1 This is the first embodiment of the present invention, which provides a device for repairing irregularly shaped pipes, capable of adjusting the angle of the spray head to improve the repair effect of irregularly shaped pipes, including:

[0031] The main body 100 is equipped with a storage cylinder 101 for storing the repair coating for irregular pipes. Three sets of brackets 102 are installed at both ends of the main body 100. Each set of brackets 102 is slidably connected with a telescopic rod 103, and the telescopic rod 103 is equipped with a roller 105.

[0032] It should be noted that the main body 100 can be moved into the interior of the irregular pipe by a traction device. The storage cylinder 101 is used to store the repair coating for the leak in the irregular pipe. The repair coating can be epoxy resin or polyurea coating, which can form a new protective layer at the leak in the irregular pipe. Before use, the electrical terminals of each electrical device are electrically connected to the electrical terminals of the power supply and controller through wires.

[0033] The rotating assembly 200 includes a circular sleeve 201 disposed on the storage cylinder 101, an arc-shaped movable box 203 rotatably disposed on the circular sleeve 201, and a spray head 107 and a camera 108 connected to the storage cylinder 101 mounted on the arc-shaped movable box 203.

[0034] During use, the telescopic rod 103 rolls within the bracket 102, causing the roller 105 to contact the inner wall of the irregularly shaped pipe. This facilitates the main body 100's smooth entry into the pipe via the traction device. The camera 108 transmits the captured image to an external display screen in real time, allowing staff to check whether the repair position has been reached. The arc-shaped moving box 203 on the rotating component 200 moves in a circular motion on the sleeve 201, thereby adjusting the position of the spray head 107 to align with the leak in the irregularly shaped pipe. The spray head 107 then sprays the coating material onto the leak in the irregularly shaped pipe, thus completing the repair work.

[0035] Example 2

[0036] Reference Figures 1 to 4This is the second embodiment of the present invention. Unlike the previous embodiment, a material pump 109 is fixedly connected to the storage cylinder 101. The inlet of the material pump 109 is connected to a feed pipe 110, and the end of the feed pipe 110 away from the material pump 109 is connected to the storage cylinder 101.

[0037] The material pump 109 is equipped with a conveying pipe 111 at its outlet, and the end of the conveying pipe 111 away from the material pump 109 is connected to the spray head 107. The operation of the material pump 109 causes the feed pipe 110 to generate suction, which conveys the repair material in the storage cylinder 101 to the spray head 107.

[0038] The telescopic rod 103 has multiple sets of positioning holes 104, and the bracket 102 is threaded with locking screws 106 that are connected to the positioning holes 104. After the roller 105 is in contact with the inner wall of the irregular pipe, the locking screws 106 are rotated to make them threadedly connected to the corresponding positioning holes 104, thus fixing the position of the telescopic rod 103 and facilitating the smooth movement of the main body 100 into the irregular pipe.

[0039] The rotating assembly 200 also includes multiple sets of meshing grooves 202 formed on the circular sleeve 201, with the open end of the arc-shaped moving box 203 facing the meshing grooves 202.

[0040] Among them, a motor 204 is fixedly connected to the arc-shaped moving box 203, and the output end of the motor 204 is connected to a gear 208 through a rotating shaft. The gear 208 is engaged with the meshing groove 202.

[0041] The circular sleeve 201 has a circular groove 205, and an arc-shaped block 206 is rotatably disposed in the circular groove 205. A connecting rod 207 is fixedly connected to the outer wall of the arc-shaped block 206, and the end of the connecting rod 207 away from the arc-shaped block 206 is fixedly connected to the arc-shaped moving box 203. The operation of the motor 204 drives the gear 208 to rotate. Since the gear 208 is engaged with the multiple sets of meshing grooves 202 on the circular sleeve 201, and the arc-shaped moving box 203 is limited by the sliding of the connecting rod 207, the arc-shaped block 206 and the circular groove 205, the arc-shaped moving box 203 can make circular motion on the circular sleeve 201, thereby adjusting the angle of the spray head 107.

[0042] The storage cylinder 101 is equipped with a feeding pipe that is connected to it, and the feeding pipe is threaded with a cap; after opening the threaded cap, it is convenient to add repair material into the storage cylinder 101.

[0043] When in use, the main body 100 is moved into the irregular pipe so that the roller 105 fits against the inner wall of the irregular pipe. After the roller 105 fits against the inner wall of the irregular pipe, the locking bolt 106 is rotated to make it threadedly connected with the corresponding positioning hole 104, thus fixing the position of the telescopic rod 103. The main body 100 is then moved into the irregular pipe in conjunction with the traction equipment.

[0044] Then, the camera 108 observes the angle of the spray head 107, and the controller causes the motor 204 on the rotating assembly 200 to work, which drives the gear 208 to rotate. Since the gear 208 is engaged with the multiple sets of meshing grooves 202 on the sleeve 201, and the arc-shaped moving box 203 is limited by the connecting rod 207, the arc-shaped block 206 and the circular groove 205, the arc-shaped moving box 203 can make circular motion on the sleeve 201, thereby adjusting the angle of the spray head 107. The material pump 109 works to transport the repair material in the storage cylinder 101 to the spray head 107, and the spray head 107 sprays the spray material to the leak in the irregular pipe, thereby realizing the repair work of the irregular pipe.

[0045] It is worth noting that the entire device is controlled by a controller. Since the controller is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0046] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0047] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
