[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. 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.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] Example 1: Reference Figures 1-6 An adjustable diameter pipe partial repair sealing assembly includes: an upper mounting plate 1, a lower mounting plate 2, a locking assembly 3, a fixing platform 4, and an arc-shaped rubber sheet 5. Each of the upper mounting plate 1 and the lower mounting plate 2 is connected to the end of a fixing platform 4. The other ends of the two fixing platforms 4 are arranged opposite each other. The end of the arc-shaped rubber sheet 5 is connected to the arc-shaped groove opened at the other end of the fixing platform 4. The upper mounting plate 1 and the lower mounting plate 2 are connected by the locking assembly 3.

[0026] The principle behind the above scheme is as follows:

[0027] Each of the upper mounting plate 1 and the lower mounting plate 2 is connected to a fixed platform 4. When using the device, first determine the damaged area of ​​the pipe, then move the upper mounting plate 1 and the lower mounting plate 2 to the damaged area, so that the axis of the arc groove of the fixed platform 4 is collinear with the axis of the pipe. At this time, use the locking assembly 3 to connect the upper mounting plate 1 and the lower mounting plate 2, and bring the two fixed platforms 4 close to each other. The arc rubber sheet 5 connected to the arc groove of one fixed platform 4 contacts the damaged area, and the other arc rubber sheet 5 contacts the side wall of the pipe away from the damaged area. After locking the assembly 3, the arc rubber sheet 5 completes the sealing of the damaged area.

[0028] The beneficial effects of the above scheme are as follows:

[0029] The device has a fixed platform 4 connected to the upper mounting plate 1 and the lower mounting plate 2. The fixed platform 4 has an arc-shaped groove. The radius of the arc-shaped groove is adjusted to be equal to the radius of the pipe to be sealed. Then, the arc-shaped rubber sheet 5 makes good contact with the side wall around the damaged part of the pipe, which improves the sealing effect of the device for pipes of different radii.

[0030] Example 2: Reference Figures 1-6 The upper mounting plate 1 and the lower mounting plate 2 each have a mounting groove 6, the two mounting grooves 6 are arranged opposite to each other, and the end of a fixing platform 4 is inserted into each mounting groove 6.

[0031] The principles and beneficial effects of the above scheme are as follows:

[0032] To facilitate the replacement of the fixed platform 4 with arc grooves of different radii, a mounting groove 6 is opened on the upper mounting plate 1 and the lower mounting plate 2 respectively. The mounting groove 6 is inserted into the end of the fixed platform 4 to improve the efficiency of the fixed platform 4 replacement.

[0033] Example 3: Reference Figures 1-6 The fixed platform 4 has a horizontal slot 7 on each side. The top wall and inner wall of the horizontal slot 7 are provided with a chamfer 8. The chamfer 8 contacts and cooperates with the chamfer 2 on the top of the locking strip 9. The chamfer 2 is set towards the middle of the upper mounting plate 1 and the lower mounting plate 2. The bottom of the locking strip 9 contacts and cooperates with the bottom wall of the horizontal slot 7. The side of the locking strip 9 is connected to the top of the slide 10.

[0034] The slide block 10 is slidably connected to the upper mounting plate 1 or the lower mounting plate 2, and the slide block 10 is connected to the upper mounting plate 1 or the lower mounting plate 2 by a spring 11.

[0035] The slide block 10 is connected to the end of the pull rod 12, and the other end of the pull rod 12 is set away from the fixed platform 4.

[0036] The principles and beneficial effects of the above scheme are as follows:

[0037] When the pipeline supplies water, it will make bends due to its structure. When the water flows to the bend, the change in flow velocity will impact the pipeline, causing the pipeline to vibrate. To increase the stability of the sealing between the fixing platform 4 and the arc-shaped rubber sheet 5 at the damaged point, a transverse groove 7 is opened on each side of each fixing platform 4. After the end of the fixing platform 4 is inserted into the mounting groove 6, the chamfer 2 at the top of the locking strip 9 contacts and engages with the chamfer 8 in the transverse groove 7, and the bottom of the locking strip 9 contacts and engages with the top wall of the transverse groove 7, thereby locking the fixing platform 4.

[0038] Before locking begins, the fixed platform 4 moves towards the mounting groove 6. The chamfer 2 first contacts and engages with the end of the fixed platform 4. With the sliding connection between the slide block 10 and the upper mounting plate 1 or the lower mounting plate 2, the distance between the two opposing locking strips 9 increases. At the same time, the spring 11 is compressed. When the locking strip 9 completes the engagement with the transverse slot 7, under the elastic force of the spring 11 returning to its original position, the slide block 10 drives the locking strip 9 to move. The two opposing locking strips 9 move towards each other and lock their respective transverse slots 7, preventing the fixed platform 4 from coming out of the mounting groove 6. The setting of the locking strip 9 increases the stability of the fixed platform 4 after installation. When the pipeline vibrates, with the cooperation of the arc rubber sheet 5, it can not only seal the damaged part of the pipeline, but also provide a certain degree of shock absorption under the good compression effect of the arc rubber sheet 5 itself. Under the action of the friction of the arc rubber sheet 5, it can prevent the device from deflecting, thus preventing the arc rubber sheet 5, which plays a sealing role, from losing its seal for the damaged part.

[0039] When disassembling the fixed platform 4, the lever 12 can be pulled away from the fixed platform 4, thereby pulling the locking bar 9 to unlock the horizontal slot 7.

[0040] Example 4: Reference Figures 1-6 The locking assembly 3 includes: locking rods 13, the bottom sidewalls of the two locking rods 13 are rotatably connected to both ends of the lower mounting plate 2, and the threaded part of the top sidewall of the locking rods 13 is threadedly connected to the screw hole 14 of the upper mounting plate 1.

[0041] The principles and beneficial effects of the above scheme are as follows:

[0042] After identifying the damaged part of the pipe, in order to facilitate the movement of the upper mounting plate 1 or the lower mounting plate 2 towards each other and to lock them, the upper mounting plate 1 can be moved so that its screw hole 14 is aligned with the top of the locking rod 13. During the downward movement of the upper mounting plate 1, the screw hole 14 begins to contact the threaded part of the locking rod 13. Then, the locking rod 13 is rotated so that its threaded part is threadedly connected to the screw hole 14. The bottom side wall of the rotating locking rod 13 is rotatably connected to the end of the lower mounting plate 2, so there will be no mechanical interference, which improves the efficiency of component connection.

[0043] Example 5: Reference Figures 1-6 The locking rod 13 has a cross groove 15 on its top away from the upper mounting plate 1.

[0044] The principles and beneficial effects of the above scheme are as follows:

[0045] During the rotation of the locking lever 13, a screwdriver can be inserted into the cross groove 15 to rotate it, reducing the difficulty of rotating the locking lever 13. Since the diameter of the locking lever 13 is equal from top to bottom, that is, from its top to its surface parallel to the lower mounting plate 2, two parts can be placed before installing the upper mounting plate 1 and the lower mounting plate 2. When installation is required, the locking lever 13 and the screw hole 14 can be aligned, thus facilitating the installation of the device at the damaged area.

[0046] Example 6: Reference Figures 1-6 The locking rod 13 has multiple slots 16 arranged in a circumferential array on the bottom side wall away from the lower mounting plate 2, and the slots 16 are inserted into the end of the insertion rod 17.

[0047] The principles and beneficial effects of the above scheme are as follows:

[0048] The locking lever 13 has multiple slots 16 arranged in a circular array on the bottom side wall away from the lower mounting plate 2. The opening of the slots 16 reduces the overall weight of the device.

[0049] Example 7: Reference Figures 1-6 The other end of the insertion rod 17 is connected to the end of the rack 18, the groove 19 on the rack 18 is slidably connected to the top of the positioning rod 20, and the bottom of the positioning rod 20 is connected to the end face of the lower mounting plate 2 away from the fixed platform 4.

[0050] The rack 18 is meshed with the side of the gear 21, the gear 21 is connected to the rotating shaft 22, the bottom of the rotating shaft 22 is rotatably connected to the lower mounting plate 2, a torsion spring 23 is connected between the gear 21 and the lower mounting plate 2, and a cross groove 24 is opened on the top of the rotating shaft 22.

[0051] The principles and beneficial effects of the above scheme are as follows:

[0052] Before rotating the locking lever 13, insert the end of a screwdriver into the cross-shaped groove 24, rotate the screwdriver to drive the rotating shaft 22 to rotate, and simultaneously rotate the gear 21. The rotating shaft 22 stores elastic potential energy, and the two racks 18 that are meshed with the gear 21 move closer to each other under the sliding cooperation of the slide groove 19 and the positioning rod 20. At this time, the ends of the two insert rods 17 are moved out of the slot 16. Then, rotate the locking lever 13 that is already threaded into the screw hole 14, and the upper mounting plate 1 and the lower mounting plate 2 move towards each other. The arc-shaped rubber sheet 5 is used to seal the damaged part of the water supply pipe. After sealing, loosen the screwdriver. Under the elastic force of the torsion spring 23 returning to its original position, the rotating shaft 22 and the gear 21 reverse, and the two racks 18 that are meshed with the gear 21 move closer to each other. Move away from each other, and each of the two rods 17 will engage with the slot 16 to prevent the locking rod 13 in the sealed pipe from rotating, thus avoiding seal failure. If, after loosening the screwdriver, one rod 17 engages with the slot 16, but the other slot 16 cannot be engaged with the other rod 17, it can be seen that the locking rod 13 that is not fixed by the rod 17 cannot rotate properly. To prevent seal failure, the locking rod 13 needs to be rotated clockwise or counterclockwise until the other rod 17 engages with the other slot 16. To further ensure the seal, at this time, you can visually check whether the tops of the two locking rods 13 are on the same horizontal plane. If they are in the same position, the locking is successful. If they are not in the same position, rotate them again until the tops of the two locking rods 13 are parallel.

[0053] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
