Description

Technical Field

[0001] This utility model belongs to the field of pipeline protection technology, specifically referring to a device for preventing water supply pipelines from freezing and cracking. Background Technology

[0002] Water supply pipes are used to transport various liquid media such as domestic water, industrial water, and fire-fighting water. In cold regions, water supply pipes face the risk of freezing and cracking due to the expansion of the internal water caused by low temperatures.

[0003] Traditional methods for preventing water supply pipes from freezing typically involve wrapping the pipes with a single type of insulation material to prevent them from cracking. However, this method is inconvenient when dealing with different types of water supply pipes, requiring the insulation material to be cut and bundled for installation. Furthermore, the method of bundling the insulation material is susceptible to corrosion due to the surrounding environment, resulting in poor antifreeze performance. Therefore, a water supply pipe antifreeze cracking device is proposed to solve the above problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing methods require certain cutting and bundling of the insulation material, which is inconvenient during installation. In addition, the method of bundling the insulation material is easily affected by the surrounding environment, which leads to corrosion of the material and poor antifreeze effect.

[0005] To achieve the above functions, the technical solution adopted by this utility model is as follows: a water supply pipeline anti-freezing and cracking device, including a semi-circular collar and a semi-circular ring arranged opposite each other, and two sets are symmetrically arranged. The lower end of one side of the semi-circular collar is fixedly connected to the lower end of one side of the semi-circular ring. A second heat insulation layer is fixedly connected between the two semi-circular collars, and a first heat insulation layer is fixedly connected between the two semi-circular rings. The semi-circular collar and the semi-circular ring form a circular groove for accommodating the pipeline. An adjustment mechanism for adjusting the size of the circular groove is provided on the semi-circular collar and the semi-circular ring.

[0006] Furthermore, both the first and second insulation layers have a vacuum layer inside.

[0007] Furthermore, the adjustment mechanism includes a slide groove fixedly formed on the upper end of the semi-circular collar, and a limit block is slidably arranged on the upper end of the semi-circular collar, with the length of the two limit blocks being the same as the width of the slide groove. A plurality of L-shaped limit grooves located on both sides of the slide groove and cooperating with the limit blocks are evenly formed on the semi-circular collar.

[0008] Furthermore, a connecting block is fixedly connected to the upper end of the limiting block.

[0009] Furthermore, a sealing strip is fixedly connected to one side of the semi-circular collar, and the semi-circular collar, the sealing strip, and the second thermal insulation layer form a semi-circular groove, and the thickness of the groove is equal to that of one end of the first thermal insulation layer.

[0010] Furthermore, the semi-circular collar, semi-circular ring, and sealing strip are all made of elastic rubber material.

[0011] The beneficial effects of this utility model by adopting the above structure are as follows:

[0012] 1. It is equipped with an adjustment mechanism. By sliding the limiting block, it can slide along the groove and slide the semi-circular ring into the groove formed by the semi-circular collar and the sealing strip. The size of the circular groove can be flexibly adjusted to adapt to pipes of different sizes, improving the versatility of the device. After adjustment, by pulling the limiting blocks to both ends, it can be put into the L-shaped limiting groove and fixed under the action of tension.

[0013] 2. The vacuum layer inside the insulation layer one and insulation layer two can effectively block cold air, reduce heat loss, prevent freezing and cracking caused by the expansion of water in the pipe, and improve the antifreeze effect. Attached Figure Description

[0019] The accompanying drawings are provided to further understand the present invention and form part of the specification. They are used together with the embodiments of the present invention to explain the present invention and do not constitute a limitation thereof. Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model. Example

[0021] refer to Figure 1 and Figure 2 As shown, in order to achieve the above functions, the technical solution adopted by this utility model is as follows: A water supply pipeline antifreeze cracking device includes a semi-circular collar 1 and a semi-circular ring 2 arranged opposite to each other, and two sets are symmetrically arranged. The lower end of one side of the semi-circular collar 1 is fixedly connected to the lower end of one side of the semi-circular ring 2. A second heat insulation layer 5 is fixedly connected between the two semi-circular collars 1, and a first heat insulation layer 4 is fixedly connected between the two semi-circular rings 2. The semi-circular collar 1 and the semi-circular ring 2 form a circular groove for accommodating the pipeline. An adjustment mechanism for adjusting the size of the circular groove is provided on the semi-circular collar 1 and the semi-circular ring 2.

[0022] like Figure 2 and Figure 3 As shown, the adjustment mechanism includes a groove fixedly opened on the upper end of the semi-circular collar 1. A limiting block 6 is slidably installed on the upper end of the semi-circular ring 2, and the lengths of the two limiting blocks 6 are the same as the width of the groove. Multiple L-shaped limiting grooves 8, located on both sides of the groove and cooperating with the limiting blocks 6, are evenly opened on the semi-circular collar 1. A connecting block 7 is fixedly connected to the upper end of the limiting block 6. The semi-circular collar 1, semi-circular ring 2, and sealing strip 3 are all made of elastic rubber material. During installation, the semi-circular collar 1 and semi-circular ring 2 are wrapped around the outside of the water supply pipe to be protected, so that the pipe is located within the circular groove. When adjusting the size of the circular groove, the limiting block 6 is pushed to slide within the groove by the connecting block 7. For smaller pipes, the limiting block 6 is slid into the L-shaped limiting groove 8 near the inner side of the semi-circular collar 1, causing the semi-circular ring 2 to move inward, reducing the diameter of the circular groove. After adjustment, the limiting block 6 is slid into the corresponding L-shaped limiting groove 8 to engage, achieving fixation under tension. Example

[0023] Based on Example 1, in order to further enhance the antifreeze effect, such as... Figure 1-4As shown, both the first insulation layer 4 and the second insulation layer 5 have a vacuum layer 9 inside. The second insulation layer 5 includes two opposing annular layers, each with a vacuum layer 9 inside, effectively preventing outside cold air from contacting the pipe. A sealing strip 3 is fixedly connected to one side of the semi-circular collar 1. The semi-circular collar 1, the sealing strip 3, and the second insulation layer 5 form a semi-circular groove, and the thickness of the groove is equal to one end of the first insulation layer 4, so that when cold air enters between the two annular layers from the groove, it is blocked and cannot contact the pipe.
