Technical Field

[0001] The utility model relates to the technical field of pipeline antifreezing, in particular to a pipeline antifreezing device for a rural water supply project. Background Art

[0002] In rural areas, some water pipes are exposed outdoors. Therefore, in the cold winter, the water inside the pipes may freeze, affecting the normal water use of residents. In severe cases, the pipes may freeze and crack. Therefore, it is necessary to add corresponding anti-freeze measures on the surface of these pipes. Existing measures usually involve wrapping insulation cotton and other items on the surface of the pipes to insulate and prevent them from freezing.

[0003] After searching, the existing patent (publication number: CN221567327U) discloses a rural water supply project pipeline antifreeze device, including a bottom fixed plate, a No. 1 connecting plate is provided above the bottom fixed plate, a No. 1 rotating plate is provided at the bottom of the No. 1 connecting plate, a No. 2 connecting plate is provided above the No. 1 connecting plate, and a No. 2 rotating plate is provided on the top of the No. 2 connecting plate. The beneficial effect of the present invention is to cut a sponge tube that is compatible with the length of the water supply pipe exposed above the soil, and then wrap the sponge tube on the outside of the water pipe, and then wrap the No. 1 connecting plate and the No. 2 connecting plate on the outside of the sponge tube, adjust the No. 2 connecting plate to move up and down inside the No. 1 connecting plate, so that the length of the No. 1 connecting plate and the No. 2 connecting plate is compatible with the length of the sponge tube, thereby fixing and protecting the sponge tube to prevent the sponge tube from being damaged, which causes the sponge tube to fail to play the role of heat preservation and antifreeze, thereby increasing the service life and stability of the sponge tube.

[0004] However, in the above scheme, the maximum sliding length of the No. 1 connecting plate and the No. 2 connecting plate is fixed, which makes it inconvenient to assemble and splice the water pipe of any length when the length is too long. In addition, there is a gap between the sliding of the No. 1 connecting plate and the No. 2 connecting plate, so that rainwater or cold air will enter the interior of the No. 1 connecting plate, which will cause corrosion to the sponge tube. At the same time, after some water freezes in the gap between the No. 1 connecting plate and the sponge tube, it will also affect the insulation effect of the water pipe, resulting in inconvenience in its use.

At the same time, some water will freeze in the gap between the No. 1 connecting plate and the sponge tube, which will also affect the insulation effect of the water pipe, resulting in inconvenience in its use.

[0030] In this embodiment, when performing splicing and assembly, the block 104 at the bottom end of the lower fixed half ring 3 is clamped into the inside of the slot 101, and then the elastic force of the fixing spring 107 is used to make the positioning block 106 slide and clamp into the inside of the positioning hole 103, so that the block 104 and the inside of the slot 101 are firmly engaged and fixed, and then the splicing and fixation between the lower fixed half ring 3 and the upper fixed half ring 7 can be achieved, thereby realizing the rapid splicing and assembly between the left corrugated hose 2 and the right corrugated hose 6, so that it can meet the protection action of the surface insulation pipes of water pipes of different lengths.

After that, release the pull rod 105, and use the elastic force of the fixing spring 107 to make the positioning block 106 slide into the inside of the positioning hole 103, so that the blocking block 104 is firmly clamped and fixed to the inside of the clamping groove 101, thereby realizing the splicing and fixation between the lower fixing half ring 3 and the upper fixing half ring 7, thereby realizing the rapid splicing and assembly between the left corrugated hose 2 and the right corrugated hose 6, so that it can meet the protection action of the surface insulation pipes of water pipes of different lengths, and the individually damaged left corrugated hose 2 and right corrugated hose 6 can also be disassembled for replacement;

[0047] At the same time, by utilizing the material characteristics of the left corrugated hose 2 and the right corrugated hose 6 themselves, the left corrugated hose 2 and the right corrugated hose 6 can be TPU tubes, so that they have certain ductility and softness, and then at the bend of the water pipe, the left corrugated hose 2 and the right corrugated hose 6 can also be conveniently and smoothly installed and fixed, thereby improving their applicability.
