When a pipe with a larger diameter is placed between the fixing ring and the heat-insulating cotton, the inner diameter of the heat-insulating cotton and the fixing ring will expand, and a gap will be generated, causing cold air to contact the lower outer wall of the pipe through the gap, resulting in an incomplete heat-insulating effect and failing to meet production needs. Therefore, a water supply pipe antifreeze and heat-insulating device is proposed to solve the above-mentioned problems. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides an antifreeze and heat-insulating device for water supply pipes, which has the advantages of heat-insulating and antifreezing different pipes and comprehensive heat-insulating. It solves the problem that when a pipe with a larger diameter is placed between a fixing ring and the heat-insulating cotton, the inner diameter of the heat-insulating cotton and the fixing ring expands, resulting in a gap, causing cold air to contact the outer wall of the lower side of the pipe through the gap, resulting in insufficient heat-insulating effect.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a water supply pipe antifreeze and heat preservation device, comprising a plurality of heat preservation boxes, a plurality of the heat preservation boxes are provided with antifreeze and heat preservation devices for the water supply pipes, a plurality of the heat preservation boxes are provided with heating devices for heating the water supply pipes at the front ends, and a plurality of the heat preservation boxes are provided with supporting devices for supporting the water supply pipes on the upper and lower sides.

[0018] 2. The antifreeze and heat preservation device for water supply pipes pushes the clamping plate to move toward the outside of the fixing ring by twisting the thread of the threaded rod, and cooperates with the sealing strip on the inner wall of the limit sleeve to better resist the clamping fixing ring to avoid shaking in the insulation box. It solves the problem that when a pipe with a larger diameter is placed between the fixing ring and the insulation cotton, the inner diameter of the insulation cotton and the fixing ring will expand, resulting in a gap, causing cold air to contact the outer wall of the lower side of the pipe through the gap, resulting in insufficient insulation effect.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Embodiment 1:

[0026] See also Figure 1-4In this embodiment, a water supply pipe antifreeze and heat preservation device includes a plurality of heat preservation boxes 1, wherein the plurality of heat preservation boxes 1 are provided with antifreeze and heat preservation devices for water supply pipes, the front ends of the plurality of heat preservation boxes 1 are provided with heating devices for heating water supply pipes, and the upper and lower sides of the plurality of heat preservation boxes 1 are provided with supporting devices for supporting water supply pipes. The antifreeze and heat preservation device includes a fixing ring 9 inserted into the inner side of the heat preservation box 1, an air bag 10 attached to the inner wall of the fixing ring 9, and an insulation layer 12 attached to the inner wall of the air bag 10. The heating device includes a heating box 14 fixedly connected to the front end face of the heat preservation box 1, two exhaust fans 15 embedded and installed on the lower side of the heating box 14, two heating pipes 16 fixedly installed on the inner wall of the heating box 14, and two exhaust pipes 13 connected to the upper side of the heating box 14.

[0027] Among them, the supporting device includes a threaded rod 4 threadedly connected to the upper and lower sides of the insulation box 1, a clamping plate 5 rotatably connected to the lower side of the threaded rod 4 and two telescopic rods 6 fixedly connected to the clamping plate 5 near the side of the threaded rod 4. A plurality of insulation boxes 1 are provided with fixing components on the left and right sides for fixing the connection between adjacent insulation boxes 1. The fixing components include two clamping blocks 2 inserted between the two insulation boxes 1 and two clamping grooves 3 opened on the left and right sides of the insulation box 1. Auxiliary components for supporting the outer wall of the fixing ring 9 are provided on the left and right sides of the insulation box 1. The auxiliary components include a limiting sleeve 7 inserted on the left and right sides of the insulation box 1 and a sealing strip 8 embedded in the inner wall of the limiting sleeve 7. The inner wall of the sealing strip 8 is sleeved on the outer wall surface of the fixing ring 9. An air nozzle 11 is inserted at the upper left end of the outer side of the fixing ring 9. The lower side of the air nozzle 11 passes through the fixing ring 9 and is connected to the upper side of the airbag 10. The two exhaust pipes 13 are respectively connected to the upper and lower opposite surfaces of the insulation box 1.

[0028] It should be noted that the inside of the airbag 10 is mixed with materials with good heat transfer, such as graphene and carbon fiber. When the heat energy flow in the insulation box 1 is transferred to the inside of the fixing ring 9, the materials with good heat transfer can be used to transfer the heat energy to the insulation layer 12 and to the surface of the water supply pipe. When the gas in the airbag 10 is transported, it is necessary to use a sealing cover to block the upper end of the gas nozzle 11 to prevent gas leakage.

[0029] Embodiment 2:

[0030] See also Figure 1 , Figure 2 and Figure 4 On the basis of the first embodiment, it includes a sealing sleeve 17 fixedly connected to the inner walls of the upper and lower sides of the heat preservation box 1.

[0031] By adopting the above technical solution, the outer side of the threaded rod 4 passes through the sealing sleeve 17 and extends into the interior of the insulation box 1. During the rotation of the threaded rod 4, the sealing sleeve 17 can prevent the heat energy in the insulation box 1 from leaking out, thereby effectively extending the heat preservation time of the insulation box 1.

[0032] The working principle of the above embodiment is:

[0033] The water supply pipe is inserted into the interior of the fixing ring 9 from one end, the air pump is connected to the air nozzle 11 and the air is exhausted into the fixing ring 9, the gas is directly discharged into the air bag 10 and expands rapidly, while the expansion drives the insulation layer 12 to move to the outer wall of the water supply pipe and fit to it, so as to improve the thermal insulation between the water supply pipe and the fixing ring 9. The entire fixing ring 9 is inserted into the interior of the insulation box 1 from one end, and multiple insulation boxes 1 are arranged horizontally according to the overall length of the fixing ring 9. The card blocks 2 are taken out and inserted into the card slots 3 opened on the upper and lower sides of the insulation box 1 respectively, and then the bolts are used to realize the fixed connection. During the insertion of the fixing ring 9 into the insulation box 1, The sealing strips 8 in the limit sleeves 7 on the left and right sides of the insulation box 1 realize the supporting effect, and then the threaded rod 4 is threadedly rotated to push the clamping plate 5 to move to the side of the fixed ring 9 to improve the supporting purpose, and the exhaust fan 15 and the heating tube 16 in the heating box 14 are started. The heat energy generated by the heating tube 16 is combined with the wind energy of the exhaust fan 15 that blows the external gas into the heating box 14 to form a heat flow, which moves upward and is blown from the exhaust pipe 13 from the upper and lower sides of the insulation box 1 to the fixed ring 9 in parallel, wherein the heat energy is transferred to the insulation layer 12 through the air bag 10 and then transferred to the surface of the water supply pipe to achieve the purpose of insulation and antifreeze.
