Description

Technical Field

[0001] This utility model relates to the field of pipeline maintenance technology, specifically to a self-priming pipeline emergency repair device based on neodymium iron boron magnets. Background Technology

[0002] In industrial production, municipal construction, and various fluid transportation systems, pipelines, as crucial transport carriers, are highly susceptible to damage and leakage due to corrosion, external impacts, and aging during long-term use. Timely repairs are essential to prevent further losses. Currently, commonly used pipeline repair devices employ a structure where two semi-circular pipes are joined together. These pipes are secured to the outside of the damaged pipeline using bolts and other fasteners to achieve sealing and repair. However, existing devices have several shortcomings in actual installation: precise alignment and pre-tightening of the pipes require multiple people, making single-person operation extremely difficult; the locking lugs are difficult to quickly engage and position during the joining process, leading to bolt alignment difficulties and prolonging repair time; furthermore, some devices lack adequate sealing performance and structural stability, making them prone to secondary leaks in high-pressure fluid transportation environments, affecting repair effectiveness and pipeline operational safety. Utility Model Content

[0003] Therefore, this utility model provides a self-priming pipeline repair device based on neodymium iron boron magnets to solve the above-mentioned problems in the prior art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] According to a first aspect of the present invention, a self-priming pipeline repair device based on neodymium iron boron magnets includes two semi-circular tubular bodies, Body 1 and Body 2, wherein Body 1 and Body 2 can be connected to form a complete pipe body.

[0006] The connection of the main body is provided with a locking lug, and the locking lug is provided with multiple through holes. The through holes are embedded with pre-embedded nuts, and a magnetic pre-tightening component is fixed on the outside of the locking lug.

[0007] The connection of the main body 2 is provided with a locking lug 2, and the locking lug 2 is provided with a through hole 2 corresponding to the through hole 1. A magnetic pre-tightening member 2 is fixedly provided on the outside of the locking lug 2.

[0008] When the first body and the second body are connected, the first magnetic pre-tightening component and the second magnetic pre-tightening component are magnetically attracted to make the first lock lug and the second lock lug pre-tightly fit together, and are then fastened to the pre-embedded nut by bolts passing through the second through hole.

[0009] Furthermore, it also includes a clamping operating device, which includes two cross-arranged lever arms, the two lever arms being rotatably connected by a pivot, and the ends of the two lever arms being detachably connected to the outer sides of the first body and the second body, respectively.

[0010] Furthermore, it also includes a direction adjustment device, the direction adjustment device comprising:

[0011] A fixed base is provided on the outside of the tube body and its axis is perpendicular to the axis of the tube body.

[0012] The universal joint mechanism includes a ball socket and a matching ball, the ball being rotatable in multiple directions;

[0013] The adjusting rod is fixedly connected to a ball at one end and to the end of a lever arm at the other end. Multi-angle adjustment is achieved by rotating the ball.

[0014] Furthermore, both the first and second bodies have stepped grooves on their inner walls, and sealing rings are embedded in the grooves. When the pipes are connected, the sealing rings fit and seal against the outer wall of the pipe.

[0015] Furthermore, the connection between the sphere and the socket is a damped clamping structure.

[0016] Furthermore, both the outer walls of the first body and the second body are provided with multiple annular reinforcing ribs.

[0017] Furthermore, both the magnetic pretensioner one and the magnetic pretensioner two are integral strip-shaped plate structures made of neodymium iron boron magnets.

[0018] This invention has the following advantages: By setting neodymium iron boron magnetic pre-tightening components on the outer side of the locking lugs of both main bodies, when the two semi-circular tubes are joined, the magnetic pre-tightening components one and two automatically attract each other, causing the locking lugs one and two to quickly adhere and maintain a pre-tightened state. No multiple people or additional tools are required; a single person can complete precise alignment and temporary fixation, significantly reducing operational difficulty and shortening repair time. The magnetic attraction ensures that the through holes one and two on the locking lugs are completely aligned, avoiding installation difficulties caused by misaligned bolt holes in traditional devices. The pre-embedded nut embedded in the through hole one further simplifies the tightening process; only the bolt needs to be inserted for direct tightening, improving assembly efficiency.

[0028] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] Example 1

[0030] like Figures 1 to 3 As shown, a self-priming pipeline repair device based on neodymium iron boron magnets in the first aspect embodiment of this utility model includes two semi-circular tubular bodies 1 and 2. Body 1 and body 2 are usually made of engineering plastics. Body 1 and body 2 can be joined to form a complete pipe body to wrap around the outside of the damaged pipeline to achieve sealing and repair.

[0031] The connection of the main body 1 is provided with a locking lug 3, and multiple through holes 31 are opened on the locking lug 3. A pre-embedded nut 32 is embedded in the through hole 31. A magnetic pre-tightening member 4 is fixed on the outside of the locking lug 3. The connection of the main body 2 is provided with a locking lug 5, and through holes 51 corresponding to the through holes 31 are opened on the locking lug 5. A magnetic pre-tightening member 6 is fixed on the outside of the locking lug 5.

[0032] When the main body 1 and the main body 2 are connected, the magnetic pre-tightening component 4 and the magnetic pre-tightening component 6 are magnetically attracted to pre-tighten the locking lug 3 and the locking lug 5, and then the bolt 7 passes through the through hole 51 and is fastened to the pre-embedded nut 32. Both the magnetic pre-tightening component 4 and the magnetic pre-tightening component 6 are integral strip-shaped plate structures made of neodymium iron boron magnets. The neodymium iron boron magnets have extremely strong magnetic force, ensuring that the locking lug 3 and the locking lug 5 are quickly and accurately pre-tightened and fitted. This solves the problem of existing devices requiring multiple people to cooperate and having difficulty in alignment during connection, significantly improving the feasibility of single-person operation and the efficiency of emergency repairs.

[0033] Furthermore, both Body 1 and Body 2 have stepped grooves 10 on their inner walls, with sealing rings 11 embedded within them. When the pipes are connected, the sealing rings 11 fit tightly against the outer wall of the pipe. The limiting effect of the stepped grooves 10 prevents the sealing rings 11 from shifting under the impact of high-pressure fluid, significantly enhancing the sealing performance of the device and effectively preventing secondary leakage. Simultaneously, both Body 1 and Body 2 have multiple annular reinforcing ribs on their outer walls, spaced along the pipe axis. This significantly improves the overall structural stability and pressure resistance, ensuring safe and reliable operation of the device in high-pressure fluid transportation environments.

[0034] In the above embodiments, the self-adsorption and pre-tightening effect of the neodymium iron boron magnet, the effective sealing of the sealing ring, and the structural reinforcement of the annular reinforcing rib significantly improve the ease of installation, sealing performance, and structural stability of the emergency repair device, effectively solving the problems existing in the prior art.

[0035] Example 2

[0036] like Figures 1 to 3 As shown, this embodiment of a self-priming pipeline repair device based on neodymium iron boron magnets includes all the contents of embodiment 1, and in addition, it also includes a clamping operation device 8. The clamping operation device 8 includes two cross-arranged lever arms 81. The two lever arms 81 are rotatably connected by a pivot 82 to form a scissor-like structure. The ends of the two lever arms 81 are detachably connected to the outer sides of the body 1 and the body 2, respectively.

[0037] The clamping operating device 8 further reduces the operational difficulty during device installation. When connecting body 1 and body 2, the operator can easily control the opening and closing of body 1 and body 2 by holding the hand ends of the two lever arms 81 and utilizing the lever principle. Especially when the pipeline position is restricted or when operating alone, it can more accurately adjust the position of the two bodies, allowing the magnetic pre-tightening parts 4 and 6 to be smoothly attracted and pre-tightened. After the bolts 7 are tightened, the clamping operating device 8 can be removed from the body for reuse, improving the practicality and operational flexibility of the device.

[0038] The technical effects achieved by the above embodiments are as follows: the clamping operation device 8, by means of the lever principle, provides convenient operation assistance for the docking of the body 1 and the body 2, enabling the operator to control the docking process more easily, further improving the convenience of single-person operation and docking accuracy, shortening the repair time, and is especially suitable for pipeline repair operations in complex environments.

[0039] Example 3

[0040] like Figures 1 to 3 As shown, this embodiment of a self-priming pipeline repair device based on neodymium iron boron magnets includes all the contents of embodiment 2, and in addition, it also includes a direction adjustment device 9, which includes a fixed base 91, a universal connection mechanism 92 and an adjustment rod 93.

[0041] The fixed base 91 is located on the outside of the tube body and its axis is perpendicular to the tube body axis. The fixed base 91 is fixedly connected to the outer wall of the main body 1 or the main body 2, providing a stable installation base for the direction adjustment device 9. The universal connection mechanism 92 includes a ball socket 921 and a matching ball 922. The ball socket 921 is fixedly mounted on the fixed base 91. The ball 922 can rotate in multiple directions within the ball socket 921. The ball 922 and the ball socket 921 have a damping snap-fit ​​structure, that is, the ball 922 can rotate to adjust the angle when subjected to a certain external force, and can maintain the current angle position after the external force is removed, without shaking arbitrarily.

[0042] One end of the adjusting rod 93 is fixedly connected to the ball 922, and the other end is detachably connected to the end of the lever arm 81. Multi-angle adjustment of the adjusting rod 93 is achieved by rotating the ball 922 within the ball socket 921. The directional adjustment device 9 allows the lever arm 81 of the clamping operating device 8 to flexibly adjust its operating angle according to the pipeline installation environment and the operator's habits, avoiding operational obstruction caused by limited space around the pipeline, and further improving the applicability and ease of operation of the device in complex working conditions.

[0043] It should be noted that the damping engagement structure primarily relies on the fit between the surface of the ball 922 and the inner wall of the socket 921. The inner wall of the socket 921 is typically precision-machined to form an arc-shaped contact surface with a certain degree of roughness, while the ball 922 is made of high-strength, wear-resistant material, and its surface perfectly matches the curvature of the inner wall of the socket 921. Simultaneously, a ring of elastic protrusions is provided at the opening edge of the socket 921. These protrusions are made of a certain degree of elastic plastic material, and their inner diameter is slightly smaller than the diameter of the ball 922. During operation, when the ball 922 is inserted into the socket 921, the elastic protrusions at the opening edge of the socket 921 exert a certain clamping force on the ball 922, ensuring a tight fit between the ball 922 and the inner wall of the socket 921. Due to the certain roughness of the contact surfaces and the clamping effect of the elastic protrusions, the ball 922 experiences appropriate frictional force, i.e., damping force, during rotation. When the operator applies sufficient external force to rotate the ball 922, the ball 922 can overcome the damping force to achieve multi-directional rotation, thereby driving the adjusting rod 93 to adjust the angle; when the external force is removed, the damping force will keep the ball 922 in the current position, and it will not rotate randomly due to pipeline vibration or its own weight, thus ensuring the stability of the adjustment angle.

[0044] The technical effects achieved by the above embodiments are as follows: the direction adjustment device 9, through the multi-angle adjustment function of the universal connection mechanism 92 and the damping clamping structure, enables the operating angle of the clamping operation device 8 to be flexibly adjusted and fixed, effectively adapting to different pipeline installation environments, solving the problem of limited operating space, ensuring that operators can complete the docking and fastening operation of the device in the most comfortable and labor-saving way, and further optimizing the operation experience of emergency repair operations.

[0045] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.

[0046] The terms such as "upper," "lower," "left," "right," and "middle" used in this specification are merely for clarity of description and are not intended to limit the scope of implementation of this utility model. Any changes or adjustments to their relative relationships, without substantially altering the technical content, shall also be considered within the scope of implementation of this utility model.
