Plant cultivation greenhouse with cooling effect

Abstract

The invention relates to a plant cultivation greenhouse with a cooling effect. The plant cultivation greenhouse comprises a greenhouse body, first supporting plates, a sleeve frame and a cooling and dehumidifying assembly; a second supporting plate is arranged at the tops of the two first supporting plates; the sleeve frame is slidably arranged on the second supporting plate; a square pipe is arranged at the bottom of the sleeve frame, and the two ends of the square pipe are closed; an air suction fan is arranged on the left side of the square pipe, and the air suction end of the air suction fan is connected with an air inlet pipe; a waterproof breathable film is vertically arranged on the inner wall of the square pipe; a first box body is arranged at the bottom of the square pipe, and a water inlet pipe is arranged on the first box body; a water pump is arranged in the first box body, and a water outlet pipe is connected with a microporous spray head; an air outlet pipe is arranged at the closed end of the right side of the square pipe; a drying assembly is arranged in the square pipe; a control system is arranged in the greenhouse body. According to the plant cultivation greenhouse, the characteristic that water evaporation is large in heat absorption is utilized, a large amount of heat is absorbed, and therefore rapid cooling in the greenhouse body is achieved; and cold air flows through the drying assembly to be dried and dehumidified and then is discharged into the greenhouse body, and the humidity in the greenhouse body cannot be increased.

Description

technical field [0001] The invention relates to the technical field of greenhouses, in particular to a plant planting greenhouse with a cooling effect. Background technique [0002] In summer, the temperature in the shed often exceeds 40°C at noon, which leads to poor growth of vegetables and high temperature obstacles. For example, a large number of sunburned fruits, navel rotted fruits, poor flower bud differentiation, and many deformed fruits appear in solanaceous fruits, which seriously reduce planting benefits. How to reduce the greenhouse temperature is one of the most concerned issues for vegetable farmers. Many people use artificial sun protection nets to cool down. First, people need to climb to the top of the greenhouse, which poses a safety threat. Secondly, only covering the sun protection net has limited cooling effect on the greenhouse. [0003] The Chinese utility model patent notification number is CN204948921U, which proposes a plant planting greenhouse wit...

Problems solved by technology

Many use artificial sun protection nets to cool down. First, people need to climb to the top of the greenhouse, which poses a safety threat. Second, only covering the sun protection net has limited cooling effect on the greenhouse.

[0003] The Chinese utility model patent notification number is CN204948921U, which proposes a plant planting greenhouse with a cooling effect. The controller controls the movement of the walking mechanism, drives the sunscreen net to unfold, and reduces the temperature in the greenhouse. There is no need to manually cover the sunscreen net. When the sunscreen net is not effective When lowering the temperature in the greenhouse, open the corresponding number of regulating ports, turn on the fan, and the cold air in the ice storage room passes through the regulating port, the air cooling room, and the air outlet pipe successively, and finally reaches the greenhouse to reduce the temperature in the greenhouse. A lot of air-conditioning is needed, so a lot of ice cubes are needed, the supply of ice cubes is difficult to guarantee, and ice cubes need to be replenished frequently, which increases the workload
