Description

Technical Field

[0001] The utility model relates to the technical field of pipes, in particular to an anti-freezing and heat-insulating sleeve. Background Art

[0002] Pipes are building materials used for transporting fluids, gases or protecting electric wires, and are widely used in various construction, engineering and industrial fields. Different types of pipes have different connection methods, such as threaded connection, welding, hot melting connection, adhesive connection, etc.; common pipe types include metal pipes, plastic pipes, composite pipes, etc. Some pipes are directly exposed to the external environment due to the influence of the installation environment during installation. For example, some PE pipes used in solar energy are extremely easy to freeze and crack in cold weather. To reduce the damage of the pipes, a layer of thermal insulation cotton is often wrapped outside the pipes. However, the thermal insulation cotton is extremely easy to crack due to long-term exposure to wind, sun and rain, resulting in a reduction in its thermal insulation effect. Therefore, this application proposes a thermal insulation sleeve that can prevent freezing and heat insulation for pipes exposed to the external environment and avoid their freezing and cracking.

[0023] Embodiment 1

[0024] Please refer to Figures 1-6 , an anti-freezing and heat-insulating sleeve, including a sleeve assembly one 20 and a sleeve assembly two 22,

[0025] The sleeve assembly one 20 and the sleeve assembly two 22 are detachably connected by bolts 21; the sleeve assembly one 20 and the sleeve assembly two 22 are symmetrically arranged, and after being assembled, they can form a circle and can be sleeved outside the pipe 10;

[0026] The sleeve assembly one 20 includes a heat-insulating plate 24, a backing plate 25, and a water guide strip 26;

[0027] The heat-insulating plate 24 is arranged in an arc shape and is hollow inside; the backing plate 25 is fixedly connected to the left and right sides at the rear of the heat-insulating plate 24, and threaded through holes 23 are opened on the backing plate 25 for the assembly and fixation between the sleeve assembly one 20 and the sleeve assembly two 22; the water guide strip 26 is fixedly connected to the outer wall of the heat-insulating plate 24, and multiple groups of the water guide strip 26 are evenly distributed on the outer wall of the heat-insulating plate 24.

[0028] The heat-insulating plate 24 is selected as a metal composite heat-insulating plate, such as an aluminum plate, which has good heat conductivity and waterproofness; a heat-insulating coating, such as a polyurethane coating or an epoxy resin coating, is coated on the outer wall of the heat-insulating plate 24 to reduce the heat dissipation of the heat-insulating plate 24 to the outside.

[0029] The heat preservation board 24 is filled with polyurethane foam particles, which can effectively improve the heat preservation effect of the heat preservation board 24.

[0030] The water guide strip 26 is made of plastic and is set in a sealed form; it can reduce the amount of direct contact between the heat preservation board 24 and rain and snow, thereby improving the heat preservation and anti-freezing effect of the heat preservation board 24 on the pipe.

[0031] The inside of the water guide strip 26 is set to be hollow and filled with rock wool. Through the setting of rock wool, the heat preservation and anti-freezing effect of the heat preservation board 24 can be further improved.

[0032] An installation through hole is reserved on the upper side of the heat preservation board 24, and a plug cap is detachably installed therein; if the pipe 10 freezes and affects the flow of the liquid in the pipe 10, the plug cap can be removed at this time and an appropriate amount of hot water (with a temperature between 70-85 °C) can be injected into the heat preservation board 24. The hot water can accelerate the thawing of the liquid in the pipe 10, thereby ensuring the normal use of the pipe 10. Moreover, the use of the heat preservation board 24 avoids direct contact between the hot water and the outer wall of the pipe 10, and avoids the situation that the frozen pipe 10 explodes when directly contacting the hot water;

[0033] After the hot water in the heat preservation board 24 no longer has heat, the sleeve assembly one 20 and the sleeve assembly two 22 can be removed. After the hot water is poured out, a blowing device (such as a high-power hair dryer) can be used to dry the inside of the heat preservation board 24, and then the sleeve assembly one 20 and the sleeve assembly two 22 are assembled outside the pipe 10 again (this method is more suitable for pipes with a shorter length, so that the disassembly and assembly are more convenient and the blowing treatment of the heat preservation board can be carried out quickly later);

[0034] Moreover, the water absorption rate of polyurethane foam is relatively low. It is a material with a closed-cell structure and usually has good waterproof performance. It should be noted that water should not be placed in the heat preservation board 24 for a long time to avoid reducing the heat preservation performance of polyurethane foam.

[0035] The inner wall of the heat preservation board 24 is also adhered with a heat preservation layer, which is composed of a heat preservation layer one 28 and a heat preservation layer two 27;

[0036] The heat preservation layer one 28 is adhesively fixed to the inner wall of the heat preservation board 24. The heat preservation layer one 28 is composed of a sponge pad with a thickness between 5-7 mm, which can enhance the heat preservation and anti-freezing effect of the heat preservation board 24; the heat preservation layer two 27 is adhesively fixed to the rear side of the heat preservation layer one 28. The heat preservation layer two 27 is composed of soft plastic with a thickness between 3-5 mm, which can not only enhance the heat preservation and anti-freezing effect of the heat preservation board 24, but also reduce the wear between the heat preservation board 24 and the pipe 10.

[0037] During the actual operation of the embodiment of the present application, the appropriate sleeve assembly one 20 and sleeve assembly two 22 are selected according to the specifications of the exposed pipe 10, and then the sleeve assembly one 20 and sleeve assembly two 22 are assembled and fixed outside the pipe 10 through bolts 21, and the pipe 10 is insulated and protected against freezing by the heat preservation board 24; if the pipe 10 is frozen and affects the flow of the liquid in the pipe 10, the plug cap can be removed at this time and appropriate hot water (with a temperature between 70-85 °C) can be injected into the heat preservation board 24. After the hot water in the heat preservation board 24 no longer has heat, the sleeve assembly one 20 and sleeve assembly two 22 can be removed. After pouring out the hot water, a blowing device can be used to dry the inside of the heat preservation board 24, and then the sleeve assembly one 20 and sleeve assembly two 22 can be assembled outside the pipe 10 again.

[0038] The technical solution in the above embodiment of the present application has at least the following technical effects or advantages: Through the cooperation of the sleeve assembly one and the sleeve assembly two, the pipe exposed in the external environment can be protected against freezing and heat preservation, and it can be prevented from cracking.

[0039] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
