Description

Technical Field

[0001] The utility model relates to the technical field of greenhouse cooling equipment, in particular to a water curtain cooling system for an agricultural greenhouse. Background Art

[0002] The wet curtain is a special paper honeycomb structure material. Its working principle is the natural physical phenomenon of "water evaporation absorbs heat", that is, water flows from top to bottom under the action of gravity, forming a water film on the corrugated fiber surface of the wet curtain. When the fast-flowing air passes through the wet curtain, the water in the water film will absorb the heat in the air and evaporate to take away a large amount of heat, thereby reducing the temperature of the air passing through the wet curtain and achieving the purpose of cooling. The temperature inside the agricultural greenhouse is very high, and an economical and environmentally friendly cooling device is urgently needed.

[0003] In the prior art, a Chinese patent document with patent announcement number CN215736075U proposes a cooling water curtain for an agricultural greenhouse, including a greenhouse and a cooling water curtain on one side of the greenhouse, the tops of the left and right side walls of the greenhouse are both provided with rainwater collecting grooves, the cooling water curtain is arranged below the rainwater collecting grooves, the cooling water curtain includes a frame and a water curtain paper, the water curtain paper is fixedly arranged inside the frame, a water inlet pipe is arranged inside the top frame of the frame, a water collecting groove is arranged inside the bottom frame of the frame, and the rainwater collecting groove is arranged inside the bottom frame of the frame. The bottom of the collecting trough is connected with the top of the water inlet pipe through a connecting pipe. A water distribution pipe is also obliquely arranged on the cooling water curtain. One end of the water distribution pipe is connected with the water inlet pipe, and the other end is tightly connected with the top of the bottom frame. In actual use, due to the limited drainage range of the water pipe, it is easy for the water curtain paper to have local dry areas that are not soaked by the water source when absorbing water, affecting the working efficiency of the water curtain cooling. Furthermore, we disclose a water curtain cooling system for agricultural greenhouses to meet the actual needs of efficient humidification of local dry positions of the water curtain paper.
