The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0032] It should be noted that the illustrations provided in the following embodiments are only used to schematically illustrate the basic concept of the present invention. Therefore, the drawings only show the layers related to the present invention rather than being drawn according to the number, shape and size of the layers in actual implementation. In actual implementation, the type, quantity and proportion of each layer may be changed arbitrarily, and the layer layout may also be more complicated.

[0033] In the following description, numerous details are discussed to provide a more thorough explanation of the embodiments of the present invention; however, it is obvious to those skilled in the art that the embodiments of the present invention can be implemented without these specific details.

[0034] Figure 1 Schematic diagram of the structure of the intelligent spray cooling and dust suppression device in one embodiment of the utility model. Figure 1 As shown, it includes a water tank 1 for storing water, a detection device 2 for detecting ambient temperature and humidity and dust concentration, a control system 3 for generating a control signal based on the ambient temperature and humidity and / or dust concentration, a water pump 4 for operating based on the control signal, a pipeline 5 and a plurality of nozzles 6;

[0035] The detection device 2 is connected to the control system 3, the control system 3 is connected to the water pump 4, one end of the pipeline 5 is connected to the water tank 1, the other end of the pipeline 5 is set up in the dust-raising area, the multiple nozzles 6 are set at the other end of the pipeline 5, and the water pump 4 is set on the pipeline 5;

[0036] The detection device 2 is located at the edge of the coverage area of ​​the multiple nozzles 6.

[0037] The detection device 2 includes a temperature and humidity sensor and a dust concentration sensor, and both the temperature and humidity sensor and the dust concentration sensor are connected to the control system 3 via lines.

[0038] A tank cover 11 is disposed on the top of the water tank 1 , and an ultrasonic sensor 7 for detecting the water level is disposed on the inner side of the tank cover 11 . The ultrasonic sensor 7 is connected to the control system 3 via a line.

[0039] The height of the plurality of nozzles 6 is 2 meters, and the distance between any two adjacent nozzles 6 is 1.5 meters.

[0040] The temperature and humidity sensor and the dust concentration sensor are used to detect the temperature and humidity and dust concentration in the dust-raising area respectively. When the temperature is greater than the temperature threshold, or the humidity is less than the temperature threshold, or the dust concentration is greater than the concentration threshold, the control system water pump starts to pressurize the water in the pipeline, thereby forcing the water to spray out from the nozzle to form water mist, so as to cool down the dust-raising area and suppress dust.

[0041] In the present application, the detection device 2 is located at the edge of the coverage area of ​​the multiple nozzles 6, so spraying will only be stopped when the temperature, humidity and dust concentration at the edge of the coverage area of ​​the multiple nozzles 6 return to normal.

[0042] In the present application, the shape of the water tank 1 is square or cylindrical. The pipeline 5 adopts PPR pipe, which has the advantages of being non-toxic, light, pressure-resistant and corrosion-resistant.

[0043] This application is used for spraying roadside green belts, reducing dust in factories, controlling humidity, etc. The height is generally set at about 2 meters, and the nozzle spray angle is 90°. The protection area of ​​a single nozzle can reach S=πR 2 ≈12.5m 2 Considering that there should not be too much overlap between multiple nozzles, nor too much spacing to cause large blank areas, the distance between two adjacent nozzles is set to 1.5 meters, and the coverage area of ​​each nozzle is a 3m×3m rectangular area. The ten nozzles equipped with the entire sprinkler system can reach 90m 2 coverage area.

[0044] In one embodiment of the present application, the control system 3 includes a single-chip microcomputer system, an LED indicator light, an OLED display screen, a WIFI module, a buzzer, a clock module and a power supply circuit;

The PWM signal output by the single-chip is amplified by the transistor Q5 and then drives the buzzer. The buzzer can be used to prompt the water level of the water tank, environmental parameters, etc.

[0049] The buzzer is a piezoelectric buzzer, which is a sound-generating body that uses piezoelectric ceramics as an electroacoustic transducer. The core of this device is a transducer device that uses a piezoelectric ceramic sheet pasted on a metal sheet, namely a piezoelectric buzzer. Piezoelectric buzzers have the characteristics of no radio frequency noise and low power consumption, which makes them highly valued and develop very rapidly.
