[0023] The specific implementation of a large-area temperature-controlled automatic spraying device of the present invention is described in detail below with reference to the accompanying drawings.

[0024] See attached Figure 1 , attached Figure 1 It is the circuit schematic diagram of this patent, and is not equivalent to the circuit diagram. Technicians in this field can understand the circuit schematic diagram and implement this patent through their own design.

[0025] The automatic sprinkler device includes a power supply 1, a water pump 2, a nozzle 3 and a temperature control circuit. The power supply 1 supplies power to the water pump 2 and the temperature control circuit. The nozzle 3 is connected to the water pump 2, and the water pump 2 supplies water from a water source to the nozzle 3.

[0026] This patent is for large-area spraying, with high power and large water consumption. The power supply 1 adopts a three-phase four-wire AC power supply, the water pump 2 is a three-phase AC water pump, and a thermal relay 4 is connected between the power supply 1 and the water pump 2 to ensure power safety.

[0027] The temperature control circuit includes a temperature sensor 5, a temperature controller 6 and a contactor 7. The temperature sensor 5 and the contactor 7 are connected to the temperature controller 6, and the contactor 7 is connected to the power supply 1 input to the water pump 2 position.

[0028] The temperature control circuit includes a rectifier and voltage-reducing module 8, which is connected to the power supply 1. After receiving one phase of the three-phase AC power, the temperature control circuit is connected to a fuse 9, and then passes through the rectifier and voltage-reducing module 8 to obtain a DC low voltage to power the temperature control circuit.

[0029] The working process is as follows: after the water pump 2 is turned on, the sprinkler head 3 begins to spray. The temperature controller 6 receives real-time temperature feedback from the temperature sensor 5. When the temperature is lower than a threshold, the temperature controller 6 controls the contactor 7 to close the circuit of the water pump 2 and stop spraying. When the temperature is higher than a threshold, the temperature controller 6 controls the contactor 7 to open the circuit of the water pump 2 and restart the spraying.

[0030] Taking summer cooling of the factory as an example, when the outdoor temperature is above 30 degrees, the spraying starts, and when it is below 28 degrees, the spraying stops, so that the factory maintains a stable operating temperature and ensures normal production.

[0031] In addition, a time relay 10 can be set in the temperature control circuit and connected to the contactor 7. The time breaker causes the contactor 7 to produce a delayed response. When the temperature controller 6 determines that the temperature within this delay period exceeds the threshold, it controls the contactor 7 to respond on and off.

[0032] Building on the above technical solution, an intelligent control system can also be introduced, consisting of a data analysis module and a remote control module. The data analysis module collects historical temperature data and spray records, optimizing the spray strategy to improve cooling efficiency and water conservation. The remote control module allows users to remotely monitor and control the operating status of the spray system via a mobile phone app or computer software.

[0033] It should be noted that the temperature controller of this patent, which receives temperature data from a temperature sensor, determines the data, and controls the contactor through internal circuitry and chip control, is a conventional technique well known to those skilled in the art. This patent protects the technical solution formed by the circuitry, its components, and their connections.

[0034] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
