Vegetable greenhouse capable of achieving cooling and preventing exposure to sun

Abstract

The invention relates to the technical field of agricultural production, in particular to a vegetable greenhouse capable of achieving cooling and preventing exposure to the sun. The vegetable greenhouse comprises a greenhouse frame and water storage tanks and is characterized in that the rooves on two sides of the greenhouse frame are respectively eastward and westward, the two rooves are coveredwith water curtains, the water storage tanks are used for storing water, and refrigeration devices are arranged in the water storage tanks; a plurality of staggered partitions are arranged inside eachwater curtain from top to bottom, water flowing channels are formed between every two adjacent partitions and between the partitions and the edge of the water curtain, the top water flowing channel is outwardly connected with a water guide pipe which is connected to a water pump arranged in the corresponding water storage tank, and the bottom water flowing channel is outwardly connected with a draining pipe which is connected into the corresponding water storage tank; pull rods are arranged on the two rooves at the top of the greenhouse frame, and the pull rods move along the oblique direction of the rooves; rotary rods capable of achieving autorotation are connected to two sides of the top of the greenhouse frame, and two ends of the rotary rods are connected with two ends of the pull rods through traction ropes; the water curtains on the rooves are detachably connected with the pull rods.

Description

technical field [0001] The invention relates to the technical field of agricultural production, in particular to a vegetable greenhouse capable of cooling down and preventing sun exposure. Background technique [0002] The vegetable greenhouse is a frame-covered structure with thermal insulation properties. Its appearance allows people to eat off-season vegetables and fruits. Generally, the vegetable greenhouse uses a bamboo structure or a steel structure frame, covered with one or more layers of thermal insulation plastic film, thus forming a greenhouse space. The outer film can well prevent the loss of carbon dioxide produced by the growth of vegetables inside, so that the shed has a good heat preservation effect. [0003] However, when there is plenty of sunlight during the day, especially in summer, the temperature in the vegetable greenhouse is very likely to be too high due to the sun shining through the roof, and it is not conducive to the growth of vegetables to exp...
