Device for detecting internal environment of greenhouses

Abstract

The invention discloses a device for detecting internal environment of greenhouses. Through setting a first mounting cavity, a first ball screw, a first lead screw nut, a first connection block, a first forward and reverse motor, a first sliding slot, a connection slot, an insertion block and an insertion slot, the lifting movement of a detection box can be realized, and the environment parametersat different heights in the greenhouses can be detected conveniently; through setting a second mounting cavity, a second ball screw, a second lead screw nut, a second connection block, a second forward and reverse motor, a second mounting cavity, a second sliding slot, a mounting plate and a sealing plate, the horizontal movement and adjustment of the mounting plate can be realized, and the mounting plate can be driven to stretch out and draw back; during the detection, the mounting plate extends out from the outer wall of the detection box to carry out environment detection; when detection is not carried out, the mounting plate is stored in the detection box to protect detection components; and through setting a first buffer member and a second buffer member, buffer protection for a support frame can be realized so as to prolong the service life of the device.

Description

technical field [0001] The invention relates to the technical field of greenhouse detection, in particular to a detection device for the internal environment of a greenhouse. Background technique [0002] With the emergence of high molecular polymers - polyvinyl chloride and polyethylene, plastic films are widely used in agriculture. In the early 1950s, Japan, European and American countries successfully applied greenhouse films to cover hotbeds, and then covered small sheds and greenhouses with good results. my country introduced polyvinyl chloride agricultural film in the autumn of 1955. It was first used to cover vegetables in small sheds in Beijing, and achieved the effect of early maturity and increased production. The greenhouse was originally a special equipment for vegetable production. With the development of production, the application of greenhouses has become more and more extensive. At present, greenhouses have been used for potted flower and cut flower cultiv...

Problems solved by technology

[0003] However, at present, the detection of the environment in the greenhouse is still immature. It can only detect the environment, but cannot automatically adjust the detection components. Since the interior of the greenhouse is in a closed state most of the time, the internal environment of the greenhouse is prone to stratification. Therefore, the greenhouse Environmental testing data is not comprehensive enough
