Description

Technical Field

[0001] The present invention relates to the technical field of cold chain logistics equipment, and in particular to an ultra-low temperature cold storage floor insulation and anti-freezing and anti-cooling device, which is suitable for floor treatment of food, medicine and other items that need to be stored in an ultra-low temperature environment for a long time, ensuring the temperature inside the warehouse is stable, reducing energy consumption, and improving storage efficiency and safety. Background Art

[0002] With the rapid development of the cold chain logistics industry, ultra-low temperature cold storage has been widely used as a key facility to ensure product quality. However, in ultra-low temperature environments, the ground is prone to ice expansion, which causes ground damage and affects the safety and service life of the warehouse. In addition, traditional ground insulation measures often fail to effectively prevent cold air leakage, increasing energy consumption. In recent years, although a variety of designs for cold storage floor insulation have appeared on the market, they perform poorly under extreme low temperature conditions and fail to fundamentally solve the problem.

[0003] There are two common solutions to the above problems: one is to enhance the thermal insulation performance of the ground by laying multiple layers of composite materials. Although this method can improve the thermal insulation of the ground to a certain extent, it is costly and complex to construct; the other is to use an electric heating system to lay resistance wires or heating cables above the ground. This method can quickly increase the ground temperature in local areas and prevent the ground from freezing, but due to the huge power consumption, it is not conducive to energy conservation and emission reduction. Both have obvious limitations. The former is difficult to adapt to extreme low temperature environments, and the latter is not recommended for long-term ultra-low temperature cold storage due to high energy consumption.

[0004] It can be seen that the existing ultra-low temperature cold storage floor insulation solutions generally have the problems of difficult construction, high maintenance costs, and excessive energy consumption. Especially in extremely cold areas, traditional methods are difficult to meet the requirements of high efficiency and energy saving. Moreover, these solutions usually only focus on the antifreeze function of the ground, and do not consider enough aspects such as preventing cold air leakage and maintaining the temperature stability in the warehouse, thus limiting their actual application scope and effect.

[0005] Therefore, there is an urgent need for an ultra-low temperature cold storage floor insulation and anti-freezing and cold leakage device that can solve the above problems. Summary of the invention

[0006] The purpose of the present invention is to provide an ultra-low temperature cold storage floor insulation and anti-freezing and anti-cold leakage device to solve the problems existing in the above-mentioned prior art, thereby effectively avoiding frost heave damage to the cold storage floor, while reducing cold loss and reducing operating costs.

[0007] To achieve the above object, the present invention provides the following solutions:

[0031] As an implementation method, the air-barrier and moisture-proof layer 6 is made of PE material, which has good environmental aging resistance and excellent barrier performance, and can effectively prevent the moisture on the ground and underground from affecting each other.

[0032] As an implementation mode, the surface layer 5 adopts a mixed structure of reinforced concrete and corundum to ensure good strength and hardness.

[0033] As an implementation method, the gap between the base layer 1 and the surface layer 5 is filled with the foam material 7, thereby completely ensuring the sealing and improving the thermal insulation performance.
