[0024] Specifically, the overall structure of the greenhouse is supported by the bracket 3 and the arc plate 4. By starting the servo motor 6, the cylinder 7 and the rotating plate 8 above it can be driven to rotate together. As the rotating plate 8 rotates, the transparent film 9 can be rolled up, and the transparent film 9 can be limited by the arc clamping plate 11. The transparent film 9 can be tightened by the load-bearing column 10 to prevent it from flying around in the wind. At the same time, when the transparent film 9 needs to be put down, the transparent film 9 can be pulled down by the weight of the load-bearing column 10. The protective door 14 can facilitate people to enter the greenhouse. The protective net 15 can prevent animals from entering the greenhouse to trample on or steal fruits and vegetables in the greenhouse after the transparent film 9 is opened.

[0025] Reference Figure 1 , Figure 2 and Figure 3 The irrigation mechanism 2 includes a water tank 201, which is fixedly connected to the right side of the base 1. A water pump 202 is fixedly connected to the left side of the top of the base 1. The output end of the water pump 202 is connected to a hose 203. The left side of the hose 203 is connected to a water pipe 205. The water pipe 205 penetrates the support plate 5 and is connected to a plurality of nozzles 206. The top right side of the water tank 201 is connected to a water injection port 204. A fixed plate 26 is fixedly connected to the front side of the water tank 201. An observation window 27 is provided on the front side of the fixed plate 26.

[0026] Specifically, water or aqueous solutions such as medicine can be filled through the water tank 201. By starting the water pump 202, the aqueous solution in the water tank 201 can be pumped into the hose 203. The aqueous solution inside the hose 203 can be guided to the water pipe 205. The aqueous solution inside the hose 203 can be guided to the nozzle 206 through the water pipe 205. The guided aqueous solution can be sprayed out through the nozzle 206. The remaining amount of the aqueous solution inside the water tank 201 can be easily known through the observation window 27.

[0027] Reference Figure 1 , Figure 2 and Figure 3 The front right side of the front semicircular membrane 12 is fixedly connected with a controller 16, and the controller 16 is electrically connected to the servo motor 6 and the water pump 202 respectively; the outer side of the controller 16 is fixedly connected with a housing 17, and the outer side of the housing 17 is rotatably connected with a dust cover 18;

[0028] Specifically, the controller 16 can control the starting and operating power between the servo motor 6 and the water pump 202 respectively, the housing 17 can prevent the controller 16 from being damaged due to collision, and the dust cover 18 can prevent dust or rainwater from entering the controller 16 and causing damage to the internal electronic components.

[0029] Reference Figure 1 , Figure 2 and Figure 3 , a thermometer and hygrometer 19 is fixedly connected to the left side of the front end of the front semicircular membrane 12; a fixing column 20 is fixedly connected to the top of the middle arc-shaped clamping plate 11, and a solar panel 21 is fixedly connected to the top of the fixing column 20; a fixing ring 22 is fixedly connected to the outer side of the bracket 3, a limiting column 24 is fixedly connected to the left front side of the protective door 14, and a clamping column 23 is provided on the inner wall of the limiting column 24, and a clamping block 25 is fixedly connected to the middle of the left end of the protective door 14;

[0030] Specifically, the thermometer and hygrometer 19 can help personnel know the temperature and humidity conditions inside the greenhouse. The fixed column 20 can support the solar panel 21 at a certain angle. The fixed ring 22 can engage with the block 25 to fix the protective door 14 to prevent accidental opening. The limiting column 24 can limit the movement of the block 25.

[0031] Working principle: before using the device, first, support the overall structure of the greenhouse through the bracket 3 and the arc plate 4. When the greenhouse needs to be ventilated, the servo motor 6 can be started to drive the cylinder 7 and the rotating plate 8 above it to rotate together. As the rotating plate 8 rotates, the transparent film 9 can be rolled up, and the transparent film 9 can be limited by the arc clamping plate 11. The transparent film 9 can be tightened by the load-bearing column 10 so that it will not be blown away by the wind, thereby opening the transparent film 9 to facilitate venting the inside of the greenhouse. When the transparent film 9 needs to be put down, the rolled-up transparent film 9 can be released by starting the servo motor 6 to rotate in the opposite direction. At the same time, the transparent film 9 can be pulled down by the weight of the load-bearing column 10 to prevent it from getting stuck or hooked on a high place. The protective door 14 can facilitate personnel to enter the greenhouse. The protective net 15 can prevent animals from entering the greenhouse to trample or steal fruits and vegetables in the greenhouse after the transparent film 9 is opened. The water tank 201 can be filled with water or aqueous solutions such as medicine. By starting the water pump 202, the aqueous solution in the water tank 201 can be pumped into the hose 203. The aqueous solution inside the hose 203 can be guided to the water pipe 205. The aqueous solution inside the hose 203 can be guided to the nozzle 206 through the water pipe 205. The guided aqueous solution can be sprayed out through the nozzle 206. At the same time, with the spraying of the aqueous solution, the heat inside the greenhouse can be dissipated and the humidity inside can be increased, and there is no need for staff to enter manually for irrigation or spraying medicine.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
