Description

Technical Field

[0001] This utility model relates to a drainage pipe repair device. Background Technology

[0002] Over time, drainage pipes may develop localized damage, requiring repair. Repair materials can be used to repair these damaged areas. Specifically, the repair material consists of fiberglass coated with a mixed adhesive. This material is transported to the damaged area and then adhered tightly to the pipe wall, thus completing the localized repair. However, during transportation through the drainage system, contaminants or debris may adhere to the repair material, affecting its adhesion and ultimately impacting the quality of the repair. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this utility model provides a drainage pipe repair device, comprising: a support cylinder with its axis horizontally aligned in the left-right direction; a cylindrical airbag with its axis horizontally aligned in the left-right direction and its inner ring fixed to the support cylinder; repair material wrapped around the outer ring of the cylindrical airbag; a vertically positioned right end plate fixed to the right end of the support cylinder; a support ring with its axis horizontally aligned in the left-right direction and fixed to the right side wall of the right end plate; an annular airbag with its axis horizontally aligned in the left-right direction and its inner ring fixed to the support ring; and a device horizontally aligned in the left-right direction extending from the left end of the support cylinder. The support cylinder contains a screw, a threaded sleeve fixed to the left end of the inner wall of the support cylinder and threaded with the screw, a vertical left end plate fitted onto the left end of the screw (the screw passes through the left end plate), a motor fixed to the left side wall of the left end plate and whose output shaft is connected to the screw, a protective cylinder with its shaft horizontally positioned in the left-right direction, fixed to the right side wall of the left end plate and covering the repair material, a first air supply pipe connected to the annular airbag, a second air supply pipe externally connected to the right side wall of the right end plate and connected to the cylindrical airbag, and a traveling mechanism fixed to the outer ring of the right end plate and the left end plate.

[0004] Preferably, the walking mechanism includes rollers connected to the outer rings of the right end plate and the left end plate via support feet.

[0005] Preferably, it further includes: a slider fixed to the right end of the screw and slidingly engaged with the inner wall of the support cylinder.

[0006] Preferably, the right end of the protective cylinder is abutted against the left side wall of the right end plate.

[0007] Preferably, the first gas supply pipe is externally connected to the support ring.

[0008] Preferably, it also includes a traction rod fixed to the right side of the right end plate.

[0009] Preferably, both the first gas supply pipe and the second gas supply pipe are flexible tubes.

[0010] The advantages and beneficial effects of this utility model are as follows: It provides a drainage pipe repair device, which can use repair materials to perform local repair on the damaged parts of the drainage pipe; it can also completely cover the repair material during the transportation of the repair material to the damaged part of the drainage pipe, which can prevent dirt in the drainage pipe from adhering to the repair material, and avoid the adhesion effect of the repair material due to dirt adhering to the repair material, thereby ensuring the repair quality of the drainage pipe.

[0011] This invention involves pre-wrapping repair material around the outer ring of a cylindrical airbag on the outside of the drainage pipe, as follows: The right end plate is fixed by a traction rod, thus keeping the support cylinder and the threaded sleeve fixed; then, the motor drives the screw to rotate forward, causing the screw to move to the left relative to the threaded sleeve, thereby moving the motor, left end plate, and protective cylinder to the left relative to the threaded sleeve, support cylinder, and cylindrical airbag until the cylindrical airbag is fully exposed. Then, the repair material, made of glass fiber coated with a mixed adhesive, is wrapped around the outer ring of the cylindrical airbag. After wrapping, the motor drives the screw to rotate in reverse, causing the screw to move to the right relative to the threaded sleeve, thereby moving the motor, left end plate, and protective cylinder to the right relative to the threaded sleeve, support cylinder, cylindrical airbag, repair material, and right end plate, until the right end of the protective cylinder is against the left side wall of the right end plate, meaning the protective cylinder completely covers the repair material.

[0012] During the transportation of repair materials to the damaged area of ​​the drainage pipe, the protective sleeve completely covers the repair materials, preventing dirt from the drainage pipe from adhering to the repair materials. This avoids affecting the adhesion of the repair materials due to dirt adhering to them, thus ensuring the quality of the drainage pipe repair. Attached Figure Description

[0015] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0016] The specific technical solution of this utility model is as follows:

[0017] like Figure 1As shown, this utility model provides a drainage pipe repair device, including: a support cylinder 11 with its axis horizontally aligned in the left-right direction; a cylindrical airbag 12 with its axis horizontally aligned in the left-right direction and its inner ring fixed to the support cylinder 11; repair material 13 wrapped around the outer ring of the cylindrical airbag 12; a vertical right end plate 14 fixed to the right end of the support cylinder 11; a support ring 15 with its axis horizontally aligned in the left-right direction and fixed to the right side wall of the right end plate 14; an annular airbag 16 with its axis horizontally aligned in the left-right direction and its inner ring fixed to the support ring 15; a traction rod 17 fixed to the right side of the right end plate 14; a screw 21 with its axis horizontally aligned in the left-right direction and extending into the support cylinder 11 from the left end; a threaded sleeve 18 fixed to the left end of the inner wall of the support cylinder 11 and threadedly engaged with the screw 21; and a screw 21 fixed to the right end of the screw 21 and sliding against the inner wall of the support cylinder 11. The system includes a slider 22, a vertical left end plate 23 fitted onto the left end of the screw 21 (the screw 21 passes through the left end plate 23), a motor 24 fixed to the left side wall of the left end plate 23 with its output shaft connected to the screw 21, a protective cylinder 25 with its shaft horizontally positioned in the left-right direction, fixed to the right side wall of the left end plate 23, covering the repair material 13 and with its right end abutting against the left side wall of the right end plate 14, a first air supply pipe 31 externally connected to the support ring 15 and communicating with the annular airbag 16, a second air supply pipe 32 externally connected to the right side wall of the right end plate 14 and communicating with the cylindrical airbag 12, and a walking mechanism fixed to the outer ring of the right end plate 14 and the left end plate 23; the walking mechanism includes rollers 42 connected to the outer ring of the right end plate 14 and the left end plate 23 via support feet 41; the first air supply pipe 31 and the second air supply pipe 32 are both flexible hoses.

[0018] The working principle of this utility model drainage pipe repair device includes:

[0019] Repair material 13 is pre-wrapped around the outer ring of the cylindrical airbag 12 outside the drainage pipe 5. Repair material 13 is made of glass fiber coated with mixed adhesive.

[0020] Then, the entire device is moved in the drainage pipe 5 by the traction rod 17. The walking mechanism (rollers 42 connected to the outer ring of the right end plate 14 and the left end plate 23 via the support feet 41) can support the entire device to move in the drainage pipe 5. When the entire device moves to the damaged part of the drainage pipe 5, the annular airbag 16 is inflated through the first air supply pipe 31, so that the annular airbag 16 expands and locks itself tightly against the pipe wall of the drainage pipe 5, thereby keeping the support ring 15, the right end plate 14, the support cylinder 11 and the screw sleeve 18 fixed. Then, the motor 24 drives the screw 21 to rotate forward, so that the screw 21 moves to the left relative to the screw sleeve 18, thereby driving the motor 24, the left end plate 23, the protective cylinder 25 to move to the left relative to the screw sleeve 18, the support cylinder 11, the cylindrical airbag 12 and the repair material 13, until the repair material 13 is completely exposed. Figure 2As shown; then, the cylindrical airbag 12 is inflated through the second air supply pipe 32, so that the cylindrical airbag 12 expands until the repair material 13 is tightly attached to the wall of the damaged part of the drainage pipe 5, thereby completing the local repair of the damaged part of the drainage pipe 5 (if necessary, the wall of the damaged part of the drainage pipe 5 is cleaned in advance to prevent dirt on the wall of the damaged part from affecting the adhesion of the repair material 13).

[0021] After the repair is completed, the cylindrical airbag 12 is deflated through the second air supply pipe 32, causing the cylindrical airbag 12 to detach from the repair material 13; the annular airbag 16 is deflated through the first air supply pipe 31, causing the annular airbag 16 to detach from the pipe wall of the drainage pipe 5; then the entire device is moved out of the drainage pipe 5 by the traction rod 17.

[0022] Beforehand, the repair material 13 is wrapped around the outer ring of the cylindrical airbag 12 outside the drainage pipe 5, specifically as follows: The right end plate 14 is kept stationary, that is, the support cylinder 11 and the threaded sleeve 18 are kept fixed; then the motor 24 drives the screw 21 to rotate clockwise, causing the screw 21 to move to the left relative to the threaded sleeve 18, thereby driving the motor 24, the left end plate 23, and the protective cylinder 25 to move to the left relative to the threaded sleeve 18, the support cylinder 11, and the cylindrical airbag 12 until the cylindrical airbag 12 is fully exposed, and then the repair material 13 is applied. The repair material 13, made of glass fiber coated with a mixed adhesive, is wrapped around the outer ring of the cylindrical airbag 12. After wrapping, the motor 24 drives the screw 21 to reverse, causing the screw 21 to move to the right relative to the screw sleeve 18. This, in turn, moves the motor 24, the left end plate 23, and the protective cylinder 25 to the right relative to the screw sleeve 18, the support cylinder 11, the cylindrical airbag 12, the repair material 13, and the right end plate 14, until the right end of the protective cylinder 25 is in contact with the left side wall of the right end plate 14, meaning the protective cylinder 25 completely covers the repair material 13. Figure 1 As shown.

[0023] During the process of transporting the repair material 13 to the damaged part of the drainage pipe 5, the protective sleeve 25 completely covers the repair material 13, which can prevent dirt in the drainage pipe 5 from adhering to the repair material 13. This can avoid the adhesion effect of the repair material 13 due to dirt adhering to the repair material 13, and thus ensure the repair quality of the drainage pipe 5.

[0024] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
