This not only affects the normal operation of the cold storage effect, but the volume expansion caused by freezing may also damage the tank structure and shorten its service life.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a composite waterproof and heat-insulating device for a cold water storage tank, comprising: Reservoir; The protective component is installed on the water storage tank.

[0007] Preferably, the waterproof layer is sprayed polyurea, the insulation layer is rigid polyurethane foam, the heating layer is an electric heating tape, and the protective layer is a fiberglass protective plate. The waterproof layer effectively prevents water leakage, avoids the influence of the external environment on the internal temperature and water quality of the pool, and improves the long-term service life of the pool. The insulation layer effectively isolates external cold air, reduces heat loss, and maintains a stable internal temperature of the pool. The heating layer provides a continuous heat source in low-temperature environments, ensuring that the water temperature remains within an appropriate range. Through heating operations, especially under extreme low-temperature conditions, it can prevent the water from freezing, ensuring the normal use of the pool.

At the same time, the water is heated by the heating layer. The vibration of the bubbles can help the heat of the water to be distributed more evenly, and the water temperature at the bottom of the tank will not freeze due to local cooling, thus ensuring the temperature balance in the tank.
[0010] Preferably, temperature sensors are fixedly installed on both the inner wall of one side and the bottom of the inner side of the protective layer, and the water temperature in different areas is monitored in real time by the temperature sensors.

The air compressor 10 is provided on the outer wall of the horizontal pipe 7, and one end of the horizontal pipe 7 passes through the water tank 1 and the protective component 2 and is fixedly installed with the air outlet 8.
[0019] Furthermore, the waterproof layer 201 is made of sprayed polyurea, the insulation layer 202 is made of rigid polyurethane foam, the heating layer 203 is an electric heating tape, and the protective layer 204 is a fiberglass protective plate. The waterproof layer 201 effectively prevents water leakage, avoids the influence of the external environment on the internal temperature and water quality of the pool, and improves the long-term service life of the pool. The insulation layer 202 effectively isolates external cold air, reduces heat loss, and maintains a stable internal temperature of the pool. The heating layer 203 provides a continuous heat source in low-temperature environments, ensuring that the water temperature is kept within an appropriate range. Through heating operations, especially under extreme low-temperature conditions, it can prevent the water from freezing, ensuring the normal use of the pool. The protective layer 204 provides additional mechanical protection against external physical damage or chemical corrosion, extending the effectiveness of the waterproof, insulation, and heating layers, and improving the overall durability and reliability of the device. This multi-layered composite structure achieves excellent anti-icing effects through the synergistic effect of different layers, maintaining the stability and safety of the water. It is particularly suitable for applications in cold regions or requiring long-term low-temperature storage, while also optimizing the overall performance of the pool and improving energy efficiency.

The rising air bubbles and the vibration of the water can effectively increase the kinetic energy of the water flow and prevent the water from forming a stable freezing area in a low-temperature environment. At the same time, the heating layer 203 heats the water, and the vibration of the air bubbles helps to distribute the heat of the water more evenly. The water temperature at the bottom of the tank will not freeze due to local cooling, thus ensuring the temperature balance in the tank.

[0024] Secondly, the waterproof layer 201 is fixedly installed on the inner wall of the water storage tank 1.
[0025] Working principle: When in use, when the temperature sensor 11 detects that the water temperature is low, the heating layer 203 is activated to heat the water and maintain the water temperature ≥3℃. At the same time, the connecting pipe 9 is activated to release compressed air intermittently. The rising air bubbles cause the water to vibrate, making the water temperature uniform.
