Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of antifreeze devices, in particular to a heating antifreeze device for exposed sections of water supply pipelines of urban and rural buildings in cold areas in winter. Background Art
[0002] In the cold winter in northern areas, water pipes and faucets exposed to the air will freeze due to the low temperature. Even if insulation materials are wrapped around the water pipes, the water pipes will still be frozen and unusable or even cracked. Some industry insiders have invented various heating and insulation solutions, but they are all made of rigid materials and are not very suitable for pipes of different sizes (including those with bends). At the same time, existing solutions mostly use temperature sensors, which are relatively expensive. Utility Model Content
[0003] The utility model aims to provide an exposed water pipe heating device with low cost and strong applicability.
[0004] To achieve the above-mentioned purpose, the utility model provides a water pipe insulation device, which is arranged on the outside of the water pipe. The insulation device body is two layers of flexible waterproof insulating material. The width of the flexible waterproof insulating material is adapted to the circumference of the water pipe. Fixed connecting devices that are sleeved on the water pipe are provided on both sides of the flexible waterproof insulating material. A heating wire is sandwiched between the two layers of flexible waterproof insulating material. A temperature relay with an operating temperature of 0-5°C is connected in series to the heating wire.
[0005] The fixing connection device is one of a lace, a Velcro, and a magnet.
[0006] After adopting the above scheme, the flexible waterproof insulation material of the utility model is sleeved on the water pipe to play the role of the first layer of heat preservation. When the temperature reaches 0°C, the heating wire starts to heat, and when the temperature reaches 5°C, the heating wire stops heating. In this way, the temperature of the water pipe will not be lower than 0°C, ensuring that the water pipe will not freeze. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] In order to explain the technical content, structural features, achieved objectives and effects of the present invention in detail, the following is a detailed description in conjunction with the implementation modes and the accompanying drawings.
[0012] See also Figure 1 as well as Figure 2 The utility model is a water pipe insulation device, the main body 1 is composed of two layers of flexible waterproof insulating material (fabric can be selected), and laces, Velcro, and magnets (not shown in the figure) can be arranged on both sides of the main body 1, so that the main body 1 can be sleeved on the water pipe, and a heating wire 2 is sandwiched between the two layers of flexible waterproof insulating material, and a working indicator light is connected in parallel to the heating wire 2. The heating wire 2 is also connected in series with a temperature relay 3 with a working temperature of 0-5°C.
[0013] When in use, turn on the power and turn on the switch 4. When the outdoor temperature is higher than 5°C, the temperature relay 3 is in the disconnected state and the heating wire 2 does not work. When the temperature reaches or is lower than 0 degrees, the temperature relay 3 is energized and the heating wire 2 is heated. When the water pipe wall temperature reaches 5°C, the power is automatically cut off.
[0014] The outdoor part of the faucet pipe in the north is generally about 10CM, so the length of the flexible waterproof insulation material is also 10CM. Although the faucet part is not wrapped, the temperature of the adjacent water pipe is greater than 0 degrees, so the faucet will not freeze.
[0015] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent shape or structural transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
