The device includes a mist system installed inside the greenhouse, an external shading system installed outside the greenhouse, a filter device, and a high-pressure pump for extracting underground water. The mist system uses the high-pressure pump to extract underground water and send it to the mist system. The water mist with a diameter less than 50 um is sprayed through the branch pipes and mist nozzles in the mist system, and the water mist evaporates to absorb the heat in the greenhouse.

[0004] The above-mentioned scheme solves the technical problems raised in the background technology, but in actual application, the above-mentioned scheme still has certain defects, for example, the above-mentioned device uses a pressure pump to pressurize the water, and then uses a high-pressure nozzle to atomize the water mist, which quickly evaporates to absorb the indoor heat to rapidly cool down. However, the above-mentioned scheme needs to fix many water pipes on the greenhouse frame, and the water pipes are equipped with high-pressure nozzles to atomize the water mist for cooling. A large amount of water is needed for cooling once, and more water pipes, high-pressure nozzles, and other accessories are needed for installation, which increases the use cost.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figs. 1-3 As shown, this utility model provides a technical solution: a greenhouse fogging and cooling system, including a greenhouse 1 and a controller. Ventilation windows 101 are provided on both sides of the greenhouse 1. An exhaust fan is installed on one of the ventilation windows 101. The exhaust fan is turned on periodically to ventilate the greenhouse. This is a conventional setting for existing greenhouses and will not be described in detail in this solution. A main water inlet pipe 2 is fixed on the ground at the bottom of the greenhouse 1. To prevent the main water inlet pipe 2 from being exposed, this solution adopts a buried layout for the main water inlet pipe 2. It is understood that the buried layout of the main water inlet pipe 2 can not only prevent workers from tripping while walking, but also ensure that the water in the main water inlet pipe 2 is kept at a low temperature. The main water inlet pipe 2 is connected to an external water source. The external water source can be municipal pipeline water, that is, the main water inlet pipe 2 is connected to the municipal pipeline. The external water source can also be a water tank containing groundwater. The water tank is buried underground, and the groundwater is pumped into the water tank by a water pump.

[0024] Several equally spaced fogging mechanisms 3 are connected to the main water inlet pipe 2. Several equally spaced pull cables are fixed to the top of the main water inlet pipe 2. Temperature sensors 10 are fixed to the bottom of the pull cables. The number of temperature sensors 10 is equal to the number of fogging mechanisms 3, and the temperature sensors 10 are located directly above the fogging mechanisms 3. In order to improve the accuracy of temperature detection inside the greenhouse 1, the height of the temperature sensor 10 from the ground is 1 / 3 to 1 / 2 of the height of the greenhouse 1, preferably 1 / 3. The temperature sensor 10 is electrically connected to the controller.

[0025] The fogging mechanism 3 includes a water inlet, an ultrasonic atomizer 5, a central connector, and a rotating component. After water is fogged by the ultrasonic atomizer 5, it is discharged into the greenhouse 1 through the rotating component.

[0026] Specifically, as shown in Fig. 2 The water inlet member includes a water inlet branch pipe 401 fixedly communicated with the water inlet main pipe 2, a water pump 402 and an electromagnetic valve 403 are sequentially connected on the pipe body of the water inlet branch pipe 401, and the water pump 402 and the electromagnetic valve 403 are electrically connected with the controller.

[0027] As shown in Fig. 3 The middle connecting member includes a shell 6 fixed on the top of the ultrasonic atomizer 5, the mist outlet of the ultrasonic atomizer 5 is located in the space of the shell 6, a horizontal extension plate 601 is formed at the bottom of the shell 6, and a plurality of air inlet through grooves 602 are arranged on the plate body of the extension plate 601, and it can be understood that the downward arrangement of the air inlet through grooves 602 can prevent water mist from being sucked into the shell 6.

[0028] The rotating member includes an electronic fan 7, a bearing 8 is fixed on the top outside of the shell 6, a top cover 901 is fixed on the outer ring of the bearing 8, a plurality of water mist outlets 902 are arranged on the side surface of the top cover 901, a fixed shaft 903 is fixed at the bottom end of the top cover 901, a plurality of blades 904 are fixed at the bottom end of the fixed shaft 903, the blades 904 are located directly above the electronic fan 7, when the electronic fan 7 rotates, air pressure can be applied to the blades 904, so that the fixed shaft 903 generates an axial force through the blades 904, and then drives the top cover 901 to rotate, in one specific embodiment of the present scheme, an inwardly retracting extension pipe is formed at the top of the shell 6, and it can be understood that since the inner diameter of the retracting pipe is smaller than the inner diameter of the shell 6, the flow rate of air in the retracting pipe is larger during air flow, thereby promoting the rapid rotation of the top cover 901.

[0029] For the present scheme, when the greenhouse 1 is misting and cooling, the controller controls the electromagnetic valve 403 to open and controls the water pump 402 and the ultrasonic atomizer 5 to start, water is atomized by the ultrasonic atomizer 5 and enters the shell 6, and then the controller controls the electronic fan 7 to open, when the electronic fan 7 rotates, air pressure can be applied to the blades 904, so that the fixed shaft 903 generates an axial force through the blades 904, and then drives the top cover 901 to rotate, at this time, external air enters the shell 6 through the air inlet through grooves 602, the external air and the water mist are discharged together through the rotation of the top cover 901, the rotating discharge mode accelerates the diffusion speed of the water mist, reduces the cooling time in the greenhouse 1, and makes the water mist and the air more evenly distributed in the greenhouse 1, the water mist can cover a wider area during rotation, thereby achieving uniform reduction of the temperature in the greenhouse 1;

[0030] After working for a period of time, when the temperature sensor 10 at the top of one of the fogging mechanisms 3 detects that the temperature reaches the set value, the electromagnetic valve 403 of the corresponding position fogging mechanism 3 is controlled to be closed and the water pump 402 and the ultrasonic atomizer 5 are controlled to stop working, that is, the fogging mechanism 3 in another part of the higher temperature area continues to work until the temperature values detected by all the temperature sensors 10 in the greenhouse 1 are within the set value.

[0031] Although the embodiments of the present application have been shown and described, it should be understood by those ordinary skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended embodiments and their equivalents.
