Description

Water supply and drainage freeze-proof device for municipal works Technical Field The utility model relates to the technical field of water supply and drainage antifreezing, in particular to a water supply and drainage antifreezing device for municipal engineering. Background The water supply and drainage system in municipal works is at risk of freezing in cold areas, especially in winter, and in order to prevent pipelines and equipment from being frozen and damaged in low-temperature environments, an antifreezing device is needed to prevent the pipelines from being frozen. The utility model of China patent application number 202421276682.4 discloses an antifreezing device for building water supply and drainage, the technical scheme is characterized in that the heat preservation sleeve, the first arc-shaped clamping plate, the second arc-shaped clamping plate and the threaded rod are arranged, the heat preservation sleeve is sleeved on the water inlet pipe and the water outlet pipe respectively, then the first arc-shaped clamping plate and the second arc-shaped clamping plate are pushed to be in contact with the heat preservation sleeve, when the first arc-shaped clamping plate and the second arc-shaped clamping plate are in contact with the heat preservation sleeve, the threaded rod can rotate on the first arc-shaped clamping plate and penetrates through the second arc-shaped clamping plate, so that the first arc-shaped clamping plate and the second arc-shaped clamping plate are used for fixing the heat preservation sleeve, the problem that the conventional antifreezing device is used for wrapping the heat preservation layer on the periphery of the water supply and drainage pipeline, and the heat preservation operation is carried out in the pipeline is solved, but the heat preservation effect of the heat preservation layer is limited, and the heat preservation layer is easy to fall off, and inconvenient to use is caused. However, in the in-process of in-service use, above-mentioned technical scheme can only play spacing effect to some heat preservation cotton, and the fixed effect of other position heat preservation cotton is difficult to ensure, thereby the condition that the empty drum appears can not closely be laminated because of the viscidity reduction to the heat preservation cotton of some positions, and then leads to heat to pass through the air to scatter and disappear, and the heat preservation effect is relatively poor, therefore is difficult to play fine heat preservation effect to the pipeline.
