[0002] The municipal pipeline network is an important part of urban infrastructure. It is composed of multiple pipeline systems, including water supply, drainage, gas, heat, electricity, telecommunications, network communications and other pipelines and facilities. These pipeline systems jointly provide basic public services for the city and ensure the normal operation and development of the city. The water supply network is responsible for transporting purified water to each user's home. It is usually composed of large water plants, pumping stations, water pipelines, branch pipelines and metering equipment. It is an important foundation for urban residents' water use. Its construction and maintenance play a vital role in maintaining urban public health and ensuring the production and living needs of urban residents.

[0003] When a municipal pipe network is deformed or damaged, it needs to be repaired in a timely manner. The repair requires reconnecting the two ends of the damaged pipe with a new pipe. However, due to the deformation of the damaged pipe, it takes a lot of time to knock the pipe mouth back to its original shape, which is time-consuming and labor-intensive. In addition, the inner wall of the pipe mouth has poor flatness, making it difficult to insert a new pipe.

[0004] Therefore, a municipal pipe network water supply and drainage damage repair device is proposed to solve the above problems. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0024] Example:

[0025] See also Figure 1-4 The present embodiment provides a municipal pipe network water supply and drainage damage repair device, comprising a conical mold 1, one end of the conical mold 1 can fit the inner wall of the pipe after being stretched, the internal thread of the conical mold 1 is connected to a threaded barrel 3, one end of the threaded barrel 3 is connected to a connecting rod 2, one end of the connecting rod 2 is connected to a spring 5, one end of the spring 5 is installed with a rotating mechanism 6, and the rotating mechanism 6 is installed with a rotating shaft 62 that can drive the connecting rod 2 to rotate. When the municipal pipe network water supply and drainage damage repair device is in use, the conical mold 1 is inserted into the deformed interface at one end of the damaged pipe. , and then rotate the shaft 62 to drive the connecting rod 2 to rotate, and use the rotation of the connecting rod 2 to drive the threaded barrel 3 to rotate. Since the threaded barrel 3 is connected to the internal thread of the tapered mold 1, the threaded barrel 3 will gradually open one end of the tapered mold 1 when it rotates, thereby slowly expanding the deformed part of the inner wall of the pipe interface to its original state, making it convenient to insert the new pipe into the interface of the damaged pipe, completing the repair of the pipe, without the need for manual labor to spend a lot of time on hammering and repairing, and at the same time making the inside of the damaged pipe interface fit more closely with the newly connected pipe, thereby improving the repair effect.

[0026] In this embodiment, if Figure 1 and Figure 2As shown, the inner wall of the conical mold 1 is provided with internal threads, and one end of the conical mold 1 is evenly provided with multiple inclined strips to turn one end of the conical mold 1 into a cone. After one end of the conical mold 1 is stretched, the whole can fit with the inner wall of the repair pipe interface.

[0027] In this embodiment, if Figure 2 and Figure 4 As shown, sliders 21 are symmetrically installed on the top and bottom of the inner side of the connecting rod 2, one end of the connecting rod 2 is connected to the telescopic rod 4, and positioning grooves 41 are symmetrically opened on the top and bottom of the outer ring surface of the telescopic rod 4. The positioning grooves 41 on the telescopic rod 4 are slidably connected to the slider 21 on the connecting rod 2, so that the telescopic rod 4 can slide on the inner side of the connecting rod 2.

[0028] In this embodiment, if Figure 1 、 Figure 2 and Figure 4 As shown, two support seats 61 are installed on the rotating mechanism 6, and the rotating shaft 62 is rotatably connected between the inner sides of the two support seats 61. One end of the rotating shaft 62 passes through the outer side of one of the support seats 61 and is fixedly connected to one end of the spring 5. One end of the telescopic rod 4 is fixedly connected to one end of the rotating shaft 62. Therefore, the length position of the conical mold 1 can be adjusted by squeezing the spring 5 on the rotating shaft 62 through the telescopic rod 4, so that the conical mold 1 can be inserted into the pipe conveniently.

[0029] Working principle: When the municipal pipe network water supply and drainage damage repair equipment is in use, the conical mold 1 is first inserted into the deformed interface at one end of the damaged pipe, and then the manual wheel 63 is used to rotate the shaft 62. After the shaft 62 rotates, it drives the connecting rod 2 to rotate, and the rotation of the connecting rod 2 drives the threaded barrel 3 to rotate. Since the threaded barrel 3 is connected to the internal thread of the conical mold 1, the threaded barrel 3 will gradually stretch one end of the conical mold 1 when it rotates. Since one end of the conical mold 1 is evenly provided with a plurality of inclined strips, one end of the conical mold 1 is turned into a cone. After one end of the conical mold 1 is stretched, its entirety can fit with the inner wall of the repaired pipe interface, thereby slowly stretching the deformed part of the inner wall of the pipe interface to its original state, thereby facilitating the insertion of a new pipe into the interface of the damaged pipe, completing the repair of the pipe, without the need for manual labor to spend a lot of time on hammering and repairing, and at the same time making the inside of the broken pipe interface fit more closely with the newly-matched pipe, thereby improving the repair effect.
