Description

Frost crack preventing device for water supply pipeline Technical Field The utility model belongs to the technical field of pipeline protection, and particularly relates to a frost crack prevention device for a water supply pipeline. Background The water supply pipe is a pipeline for conveying various liquid media such as domestic water, industrial water, fire-fighting water and the like, and in cold areas, the water supply pipeline is at risk of frost cracking caused by freezing and expansion of internal water bodies due to low temperature. The traditional water supply pipe antifreezing mode generally adopts a single heat insulation material to wrap the pipeline so as to realize the water supply pipe antifreezing function, but the method is inconvenient in cutting and bundling the heat insulation material to a certain extent when encountering different water supply pipes, and the heat insulation material is adopted for bundling, so that the water supply pipe antifreezing device is easy to be influenced by the surrounding environment, and the material is corroded, so that the antifreezing effect is poor. Disclosure of utility model The utility model aims to solve the technical problems that the prior method is inconvenient in cutting and bundling the heat-insulating material to a certain extent, and the heat-insulating material is easy to be influenced by the surrounding environment in a bundling way, so that the material is corroded, and the antifreezing effect is poor. In order to achieve the functions, the technical scheme includes that the water supply pipeline frost crack prevention device comprises semicircular lantern rings and semicircular rings which are oppositely arranged, wherein two groups of the semicircular lantern rings are symmetrically arranged, the lower end of one side of each semicircular lantern ring is fixedly connected with the lower end of one side of each semicircular ring, a second heat insulation layer is fixedly connected between the two semicircular lantern rings, a first heat insulation layer is fixedly connected between the two semicircular rings, circular grooves for accommodating pipelines are formed by surrounding the semicircular lantern rings and the semicircular rings, and an adjusting mechanism for adjusting the sizes of the circular grooves is arranged on the semicircular lantern rings and the semicircular rings. Further, vacuum layers are arranged in the first heat insulation layer and the second heat insulation layer. Further, adjustment mechanism is including fixedly seting up the spout in semi-circular lantern ring upper end, the upper end relative sliding of semicircle ring is provided with the stopper, and the length and the spout width of two stoppers are the same, evenly seting up a plurality of L type spacing grooves that are located the spout both sides and with stopper complex on the semi-circular lantern ring. Further, the upper end of the limiting block is fixedly connected with a connecting block. Further, sealing strips are fixedly connected to one side of the semicircular lantern ring, semicircular grooves are formed by surrounding the semicircular lantern ring, the sealing strips and the second heat insulation layer, and the thickness of the grooves is equal to one end of the first heat insulation layer.
