They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within 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.

[0030] Please see Figure 1-7 This utility model provides a technical solution: a heating pipeline leak detection and automatic repair device, comprising: a feed pipe 9 installed on the upper middle side of a mounting plate 1, and a leak detector 8 connected to the lower inner side of the mounting plate 1; a cylinder 2 disposed on the outer middle part of the mounting plate 1, and an automatic repair structure connected to the middle inner side of the mounting plate 1; a movable plate 3 fixedly installed at the lower end of the cylinder 2, and a roller 4 connected to the inner side of the movable plate 3; a first motor 11 fixedly disposed on the outer inner side of the mounting plate 1, and a mounting rod 12 connected to the outer side of the first motor 11; a moving block 6 connected to the outer side of the mounting rod 12, and a mounting block 7 installed on the outer side of the moving block 6; a limit plate 19 connected to the upper outer end of the mounting block 7; a third motor 18 disposed on the left end of the mounting block 7, and a traveling wheel 13 connected to the right side of the third motor 18; placing the mounting plate 1 on the outer side of the heating pipeline, so that the mounting plate 1 drives the traveling wheel 13 to fit against the outer side of the heating pipeline; activating the third motor 18, so that the third motor 18 drives the traveling wheel 13 to move on the mounting block 7. The inner side rotates to the right, causing the traveling wheel 13 to move to the right due to friction between it and the heating pipe. This allows the traveling wheel 13 to drive the mounting plate 1 to move on the outside of the heating pipe, while the heating pipe drives the roller 4 to rotate on the middle side of the movable plate 3, facilitating the movement of the mounting plate 1. The first motor 11 is started, causing the mounting rod 12 to rotate on the inner and outer sides of the mounting plate 1. This causes the moving block 6, which is threadedly connected to the mounting rod 12, to slide inward. As the moving block 6 moves inward, it slides on the inner side of the mounting block 7. This inward movement of the moving block 6 causes one side of the mounting block 7 to slide inward, which in turn causes the mounting block 7 to drive the limiting plate 19 to rotate on the inner and outer sides of the mounting plate 1. This causes the mounting block 7 to tilt the traveling wheel 13, allowing the mounting plate 1 to rotate in a circle on the outside of the heating pipe during the movement of the traveling wheel 13.

[0031] When using this heating pipe leak detection and automatic repair device, specific details include... Figure 1 , Figure 5 and Figure 7In this process, the mounting plate 1 is placed on the upper side of the heating pipe, so that the lower side of the mounting plate 1 is in contact with the heating pipe. The roller 4 and the movable plate 3 are connected by rotation, and the vertical cross-section of the movable plate 3 is an arc structure. The cylinder 2 is activated, so that the cylinder 2 drives the movable plate 3 to rotate on the outer side of the middle of the mounting plate 1. This rotation of the cylinder 2 on the outer side of the middle of the mounting plate 1 causes the movable plate 3 to drive the roller 4 to contact the heating pipe, so that the movable plate 3 clamps the heating pipe and facilitates the limiting of the mounting plate 1.

[0032] Specific examples Figure 2 , Figure 3 and Figure 6 In the middle, the third motor 18 is started. The mounting block 7 and the traveling wheel 13 are connected by rotation. The traveling wheel 13 is symmetrically distributed about the center line of the mounting plate 1. The third motor 18 drives the traveling wheel 13 to rotate to the right inside the mounting block 7. The friction between the traveling wheel 13 and the heating pipe causes the traveling wheel 13 to move to the right. In turn, the traveling wheel 13 drives the mounting plate 1 to move outside the heating pipe. The heating pipe drives the roller 4 to rotate in the middle of the movable plate 3, which facilitates the movement of the mounting plate 1. The moving block 6 is connected to the mounting rod 12 by a thread and moves the mounting block 7. The first motor is started. 11. The first motor 11 drives the mounting rod 12 to rotate inside and outside the mounting plate 1, thereby causing the moving block 6, which is threadedly connected to the mounting rod 12, to slide inward. Under the action of the moving block 6 moving inward, the moving block 6 slides inside the mounting block 7. Under the action of the moving block 6 moving inward, the moving block 6 drives one side of the mounting block 7 to slide inward. Under the action of the mounting block 7 sliding inward, the mounting block 7 drives the limiting plate 19 to rotate inside and outside the mounting plate 1, thereby causing the mounting block 7 to drive the traveling wheel 13 to tilt. Thus, during the travel of the traveling wheel 13, the mounting plate 1 can easily rotate around outside the heating pipe.

[0033] Specific examples Figure 1 , Figure 2 and Figure 4When a leak is detected in the heating pipe by the leak detector 8, the first motor 11 is started. The moving block 6 and the mounting block 7 are connected by a sliding mechanism, and the moving blocks 6 are symmetrically distributed about the center line of the mounting plate 1. The first motor 11 drives the mounting rod 12 to rotate inside and outside the mounting plate 1, thereby causing the moving block 6, which is threadedly connected to the mounting rod 12, to slide outward. This causes the mounting block 7, which is slidably connected to the moving block 6, to drive the limiting plate 19 to rotate inside and outside the mounting plate 1. After the mounting plate 1 travels a certain distance diametrically outside the heating pipe, the connecting rod 15 and the moving plate 16 are connected by a screw thread. The moving plate 16 and the push plate 17 are connected in a threaded manner, and the vertical cross section between them forms a "T" shape. The second motor 14 is started, which drives the connecting rod 15 to rotate at the front end of the pipe repair agent tube 5. This causes the moving plate 16, which is threadedly connected to the connecting rod 15, to slide backward. The push plate 17 and the pipe repair agent tube 5 are connected in a close-fitting manner, which causes the moving plate 16 to drive the push plate 17 to slide backward. This allows the pipe repair agent inside the pipe repair agent tube 5 to be applied to the pipe leak through the valve outlet pipe 10, facilitating automatic repair of the heating pipe. The leak detection instrument 8 is model DB-3A.
