Description

Technical Field

[0001] The utility model relates to the technical field of greenhouses, in particular to a cooling structure of a greenhouse. Background Art

[0002] A greenhouse, also known as a hothouse, is a facility that allows light to pass through and keeps warm (or heats up) and is used to cultivate plants. In seasons that are not suitable for plant growth, it can provide a greenhouse growth period and increase yields. It is mostly used for cultivating or raising seedlings of warmth-loving vegetables, flowers, trees and other plants in low temperature seasons. There are many types of greenhouses, which can be divided into many categories according to different roof materials, lighting materials, shapes and heating conditions. Existing greenhouses are insulated by light-transmitting insulation covering materials, and then a thermometer or other temperature detection device is set for temperature monitoring. Through regular manual inspections, the temperature in the greenhouse is controlled to be constant at a certain value, while existing greenhouses need to be cooled by water cooling or exhaust vents.

[0003] After searching, it was found that the publication number is CN218680489U, and the name is a cooling structure for a greenhouse. The application proposed Chinese patent application number CN201820709000.2, which disclosed that the cooling structure of the greenhouse has the problem that the above-mentioned structure lacks the function of filtering dust at the air inlet end, which easily causes external dust to directly follow the wind pressure enhanced cooling structure into the interior of the greenhouse, affecting the environment inside the greenhouse. A filter plate is arranged inside the wind pressure cooling structure, and a filter is arranged inside the filter plate. The filter is used to block the dust from the outside from entering the interior of the greenhouse, and the dust on the filter is adsorbed by the dust suction component, thereby preventing external dust from entering the greenhouse, thereby improving practicality. However, the application adopts ventilation for cooling. When the outside temperature is high, the air temperature is high. The simple cooling efficiency is low, and the cooling is not ideal. At the same time, the staff is required to frequently clean the filter, which is troublesome and can be further improved.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

When cooling the greenhouse main body 1, the water pump 11 draws water from the water collecting tank 10, enters the nozzle 9 through the water pipe 7 and is sprayed out to form a water curtain. The axial flow fan 5 inside the first wind tube 4 and the second wind tube 13 is started to form flowing air. The flowing air passes through the water curtain, and the water evaporates and absorbs heat to lower the air temperature, and then flows into the greenhouse main body 1 to cool the interior of the greenhouse main body 1, thereby improving the cooling efficiency. At the same time, the water curtain formed by the nozzle 9 can not only cool down, but also, when the flowing air passes through the water curtain, the dust in the flowing air enters the water, thereby removing part of the dust in the air, thereby eliminating the trouble of frequent cleaning and dredging of the traditional filtering structure, further improving the convenience of use, and improving work efficiency.

[0036] In one embodiment, the other end of the water pipe 7 is a closed structure to prevent water leakage and ensure that water is sprayed out along the nozzle 9.

[0037] Working principle:

[0038] When cooling the greenhouse body 1, the water pump 11 draws water from the water collection tank 10, enters the nozzle 9 through the water pipe 7 and is sprayed out to form a water curtain. The axial flow fan 5 inside the first wind tube 4 and the second wind tube 13 is started to form flowing air. The flowing air passes through the water curtain, and the water evaporates and absorbs heat to reduce the air temperature, and then flows into the greenhouse body 1 to cool the interior of the greenhouse body 1, thereby improving the cooling efficiency. At the same time, the water curtain formed by the nozzle 9 can not only cool down, but also, when the flowing air passes through the water curtain, the dust in the flowing air enters the water, thereby removing part of the dust in the air, eliminating the trouble of frequent cleaning and dredging of traditional filtering structures, further improving the convenience of use, and improving work efficiency.
