[0002] Among the many media transportation methods, pipeline transportation is the most common. When facing special transportation media, there is often a need for thermal insulation. In terms of materials, general pipeline insulation sleeves will directly use glass fiber felt, cotton felt, sponge and other materials, but these materials have the disadvantages of weak thermal insulation performance, water absorption, flammability, and low strength. This may cause water absorption during use, resulting in rapid performance degradation and combustion when encountering fire. In terms of structure, long pipelines require multiple insulation sleeves to be connected and used. Generally, adjacent insulation sleeves either have no sealing structure or have a complex connection structure. Utility Model Content

[0004] The technical solution to achieve the purpose of the utility model is: a pipe insulation sleeve structure, including at least two layers of insulation sleeves, wherein the connecting head positions of the inner insulation sleeve and the outer insulation sleeve are respectively provided with mutually matching protrusions and grooves, the protrusions are inserted into the grooves, and the inner insulation sleeve and the outer insulation sleeve are connected by the matching of the protrusions and the grooves.

[0005] In the present solution, adjacent insulation sleeves are connected by means of protrusions and grooves. Specifically, the outside of the pipe is wrapped with at least two layers of insulation sleeves, and matching protrusions and grooves are provided at the joints of two adjacent insulation sleeves. The connection between the two is completed when the protrusion is inserted into the groove. The connection structure is simple and easy to install, which greatly improves the connection and installation efficiency of adjacent insulation sleeves.

[0006] Furthermore, the side walls of the groove portion and the side walls of the protrusion portion are inclined, and the gap at the opening of the groove portion is smaller than the length of the bottom wall of the groove portion, that is, it is closed; the end of the protrusion portion is larger than the tail portion, that is, it is in an inverted cone shape, and the protrusion is clamped and confined in the groove portion, so that the two adjacent layers of insulation covers will not detach, and the connection is more secure.

[0007] Furthermore, corresponding limiting mechanisms are provided on the protruding portion and the recessed portion, which can play a limiting role when the protruding portion is installed in the recessed portion.

[0008] Furthermore, the limiting mechanism includes a limiting protrusion and a limiting groove, and the limiting protrusion is snapped into the limiting groove. When the protrusion is snapped into the groove, as long as the limiting protrusion is snapped into the limiting groove, the protrusion and the groove are installed in place; it can also prevent the protrusion from sliding up and down in the groove and sliding out.

[0009] Furthermore, the limiting protrusion is located on the side wall of the protruding portion, and the limiting groove is located on the side wall of the recessed portion, so as to facilitate the clamping and limiting between the protruding portion and the recessed portion.

[0010] Furthermore, the protrusion and the groove are respectively wrapped with steel sheets, so that the protrusion can slide into the groove and the connection strength and hardness between them can be improved.

[0011] Furthermore, the insulation cover includes at least three layers of material, which are a glass fiber blanket layer, a mesoporous insulation felt layer and an aluminum foil layer from the inside to the outside. The outer layer is the place with the highest probability of contact with water and fire, so the main materials used are a waterproof and fireproof aluminum foil layer and a mesoporous insulation felt layer. In addition, the aluminum foil layer can also reflect radiation heat transfer and reduce heat transfer; and the mesoporous insulation felt has an extremely low thermal conductivity due to the properties of nano-mesoporous, and is both waterproof and high temperature resistant and non-flammable, further improving the performance and applicability of the insulation cover. The elasticity provided by the glass fiber blanket buffer layer can reduce the presence of small gaps.

[0012] By adopting the above technical solution, the utility model has the following beneficial effects:

[0013] (1) The adjacent protective covers are connected by means of a protrusion and a groove, which has a simple structure and is convenient for connection;

[0014] (2) The groove portion is configured to be closed, and the protrusion portion is correspondingly configured to be in an inverted cone shape, so that the two are not easily separated after being clamped;

DETAILED DESCRIPTION

[0024] Example:

[0025] like Figure 1 As shown, this embodiment provides a pipe insulation sleeve structure, including at least two layers of insulation sleeves, and the inner insulation sleeve 1 and the outer insulation sleeve 2 are respectively provided with mutually matching protrusions 3 and grooves 4 at the joint positions, and the protrusions 3 are inserted into the grooves 4, and the inner insulation sleeve 1 and the outer insulation sleeve 2 are connected by the matching of the protrusions 3 and the grooves 4. In this solution, the adjacent insulation sleeves are connected by the protrusions 3 and the grooves. Specifically, the outside of the pipe is wrapped with at least two layers of insulation sleeves, and the joints of the two adjacent insulation sleeves are provided with matching protrusions 3 and grooves 4. After the protrusions 3 are inserted into the grooves 4, the connection between the two is completed. The connection structure is simple and easy to install, which greatly improves the connection and installation efficiency of adjacent insulation sleeves.

[0026] like Figure 2 As shown, the side wall 6 of the groove portion and the side wall 5 of the protrusion portion are inclined, and the gap at the opening 7 of the groove portion is smaller than the length of the bottom wall of the groove portion 4, that is, it is in a closed shape; the end 8 of the protrusion portion is larger than the tail, that is, it is in an inverted cone shape, and the protrusion 3 is clamped and confined in the groove portion 4, so that the two adjacent layers of thermal insulation sleeves will not be separated, and the connection is more secure.

[0027] like Figure 3As shown, the protrusion 3 and the groove 4 are also provided with corresponding limiting mechanisms, which can play a limiting role when the protrusion 3 is installed in the groove 4. The limiting mechanism includes a limiting protrusion 9 and a limiting groove 10. The limiting protrusion 9 is engaged in the limiting groove 10. When the protrusion 3 is engaged in the groove 4, as long as the limiting protrusion 9 is engaged in the limiting groove 10, the protrusion 3 and the groove 4 are installed in place; it can also prevent the protrusion 3 from sliding up and down in the groove 4 and slipping out. The limiting protrusion 9 is located on the side wall 5 of the protrusion, and the limiting groove 10 is located on the side wall 6 of the groove, which is convenient for the clamping and limiting between the protrusion 3 and the groove 4.

[0028] Preferably, the protrusion 3 and the groove 4 are respectively wrapped with steel sheets, so that the protrusion 3 can slide into the groove 4 and improve the connection strength and hardness between them.

The outer layer is the place with the highest probability of contact with water and fire, so the main materials used are waterproof and fireproof aluminum foil layer 13 and mesoporous insulation felt layer 12. In addition, the aluminum foil layer 13 can also reflect radiation heat transfer and reduce heat transfer; and the mesoporous insulation felt has an extremely low thermal conductivity due to the nature of nano-mesopores. At the same time, it is waterproof, high temperature resistant and non-flammable, which further improves the performance and applicability of the insulation cover. The elasticity provided by the glass fiber blanket buffer layer can reduce the existence of small gaps.

[0030] Working principle: When installing the insulation sleeve layer by layer on the pipeline, the inner and outer insulation sleeve joints have the protrusion 3 and the groove 4, and the protrusion 3 can be snapped into the groove 4, and the closed-end and inverted cone-shaped structures are not easy to separate after snapping; during installation, as long as the limiting protrusion 9 is snapped into the limiting groove 10, the connection and installation of the two are completed, further preventing separation. The material of this protective sleeve is divided into three layers from the inside to the outside, which is both waterproof and fireproof.
