Background Art

[0002] A greenhouse greenhouse is an agricultural production facility with functions such as heating, heat preservation, and ventilation, which can create a suitable growth environment for plants, extend the growth period of crops, and improve yield and quality. A greenhouse greenhouse is generally composed of a steel frame or an aluminum alloy frame, and common covering materials include glass, polycarbonate plates, polyethylene films, etc. This type of greenhouse greenhouse keeps the temperature within a suitable range through heating and heat preservation in winter, and at the same time can control the air circulation through the ventilation system to avoid losses caused by too high or too low temperatures, and can adapt to different planting requirements to improve the yield and quality of crops. It is an important facility commonly used in modern agriculture. The existing problems in the existing greenhouse greenhouses mainly include the following points: 1. The temperature control is unstable. Due to the large temperature difference between the inside and outside of the greenhouse, it is difficult to control the temperature, and the temperature fluctuates greatly, affecting the growth and development of crops. 2. Most of the greenhouse environment regulation devices in greenhouse greenhouses use sunshade cloth and large negative pressure fans. The prominent problem is high energy consumption and unsatisfactory regulation effect in extreme high temperature situations in summer. Summary of the Invention

[0003] In order to solve the above technical problems, the present invention provides a water-saving intelligent greenhouse environment regulation film bag and a regulation method, which solve the technical problems of high energy consumption and inability to regulate extreme high temperature in the prior art.

[0004] The object of the present invention is achieved through the following technical solutions: A water-saving intelligent greenhouse environment regulation film bag, the greenhouse environment regulation film bag is laid on the outer top of the greenhouse greenhouse, and the specific structure is: including a plate-shaped water collection bin, the water collection bin includes a plurality of transparent bag-shaped bins, and the plurality of transparent bag-shaped bins are connected in sequence to form the water collection bin. The lower surface of the water collection bin is bonded with a lower clamping film, and the lower clamping film is laid on the outer top of the greenhouse greenhouse. An inlet is provided at the top end of the water collection bin corresponding to the top of the greenhouse greenhouse, and a pressure sensor is provided at the bottom of the water collection bin; it also includes a hot air condenser arranged inside the greenhouse greenhouse. A micro pump is provided at the water outlet of the hot air condenser, and the water inlet of the water collection bin is connected to the water outlet of the hot air condenser through a hose. The hot air condenser, the micro pump, and the pressure sensor are all connected to the automatic control main board.

[0005] For the above water-saving intelligent greenhouse environment regulation film bag, the hot air condenser is a cavity structure with a cavity body. A plurality of semiconductor refrigerators are embedded in the whole body of the cavity body. A condensate water collection tank for collecting condensate water is provided at the bottom of the cavity body. A micro pump is installed at one end of the condensate water collection tank, and a water outlet is provided at the discharge port of the micro pump. The hot air condenser is arranged on the inner top of the greenhouse.

[0006] The above-mentioned water-saving intelligent greenhouse environment control film bag is characterized in that: the hot air condenser is placed on the top inside the greenhouse through a fixing rod.

[0007] The above-mentioned water-saving intelligent greenhouse environment control film bag further includes solar panels arranged outside the greenhouse, and the solar panels supply power to the hot air condenser, the micro pump and the pressure sensor respectively.

[0008] For the above-mentioned water-saving intelligent greenhouse environment control film bag, the height of the transparent bag-shaped bin is 0.5 - 3.0 mm, and the material of the transparent bag-shaped bin is plastic.

[0009] For the above-mentioned water-saving intelligent greenhouse environment control film bag, the transparent bag-shaped bin is a plurality of long strip bag-shaped bins arranged in parallel, and adjacent long strip bag-shaped bins are connected through a plurality of short transparent short bag-shaped bins. The water inlet is connected to the water inlet pipe, and the water inlet pipe is connected to a plurality of long strip bag-shaped bins.

[0010] A method for controlling the greenhouse environment with the above-mentioned water-saving intelligent greenhouse environment control film bag includes the following steps: (1) Lay the greenhouse environment control film bag on the top of the greenhouse, and fix it on the top of the greenhouse with a film pressing belt after flattening. (2) Place the hot air condenser inside the greenhouse near the top and fix it with a fixing rod.

(5) When using it for the first time, start the hot air condenser to suck the hot air at the top inside the greenhouse, and the condensed water formed after condensation is collected and enters the greenhouse environment control film bag. When the water level reaches the high water level, the automatic control main board controls the micro pump to automatically disconnect and stop the condensed water injection. (6) After that, under the action of losses such as evaporation and leakage, when the water level in the greenhouse environment control film bag drops to the low water level, the automatic control main board controls the hot air condenser and the micro pump to start.
