The sprinkler pipes are also arranged on the surface of the concrete to be cured, and the space between the pipes is 100cm, so that an open circuit is formed. The cavitation heat pump is used for vortex pressurizing liquid to obtain kinetic energy, then the liquid flows through a throttling orifice arranged in the cavitation generator at a high speed to generate negative pressure, so that the liquid reaches a boiling point and generates tens of thousands of tiny cavitation bubbles inside, and under the action of surrounding water pressure, the bubbles collapse through impact, so that heat is generated, circulating water is heated, and the purpose of heating is achieved.

When the stop valve 6 is opened, after the cavitation heat pump 3 heats, hot water flows through the stop valve 6, one part of the hot water enters the heat preservation pipe 4 to play a heat preservation effect, and the other part of the hot water enters the sprinkler pipe 5 to be sprinkled out through the sprinkler head 11 to play a role in preserving heat and moisture. After the stop valve is closed, hot water only flows into the heat preservation pipeline to form a loop and flow into the water tank, so that the heat preservation effect is achieved.

Also included is a mobile terminal 13, the mobile terminal 13 being in communication with the control system 2. The mobile terminal 13 is a mobile phone or tablet computer.

And the heat preservation pipe also comprises a flowmeter 10, wherein the flowmeter 10 is arranged on the heat preservation pipe 4. The method is used for inquiring the accumulated flow, the instantaneous flow rate and the working state of the electromagnetic valve. Meanwhile, the over-limit alarm of the flow speed and the flow rate can be set.

The whole system takes a preset upper limit and a preset lower limit of humidity control as threshold values, when the humidity upper limit is exceeded, the main control board controls the stop valve to be closed to stop sprinkling, and when the humidity lower limit is lower than the humidity upper limit, the main control board controls the stop valve to be opened to perform sprinkling.

At this time, the water flows into the cavitation heat pump to start heating, then flows into the heat preservation pipe and the sprinkler pipe, at this time, the temperature and the humidity are necessarily lower than the threshold value because the system is just started, so that the main control board can automatically prompt the heating power and the preset temperature of the heat pump, and meanwhile, the stop valve is opened to always ensure sprinkling until the temperature and the humidity reach the preset value, and the system is kept stable. Finally, the flow and the switch state are checked through the mobile phone, if the mobile phone is not required to be used continuously, the mobile phone can be controlled to close the system, and the system is removed.

The working principle of the utility model is as follows:

(1) The mobile phone program controls the wireless control terminal to determine the opening and closing states of the system and the electromagnetic valve through controlling the main board.

(2) When the device is started, the wireless control terminal monitors data in real time according to the temperature and humidity sensor, and feeds back and adjusts the heating power and the heating temperature of the cavitation heat pump, so that the concrete surface is ensured to reach the preset temperature.

(3) When the intelligent water dispenser is started, the wireless control terminal adjusts the opening and closing frequency of the stop valve according to real-time monitoring data of the temperature and humidity sensor, when the stop valve is opened, a part of hot water flows into the water spraying pipeline to be sprayed out, and a part of hot water still circulates through the heat preservation pipeline, and meanwhile, the functions of heat preservation and moisture preservation are achieved.

(4) The cavitation heat pump is essentially different from the electric heating rod heating heat pump in that the principle is to utilize the heat efficiency of the fluid after cavitation occurs at a high speed, namely, the high-speed water flow contains a large amount of bubbles, a considerable amount of non-condensable gas is contained in the collapsing bubbles, and the collapsing speed of the bubbles is very rapid, usually in a few nanoseconds. In such a short period of time, the gas in the bubble is not cooled as much as the surrounding liquid, so that the local liquid temperature suddenly rises, and the extremely high temperature, high pressure, high jet continuously acts on the inside of the liquid several tens of thousands of times per second, resulting in a rise in the liquid temperature.

(5) The cavitation heat pump generates heat and exchanges heat through a pipeline to achieve the aim of heat preservation.
