Detailed Description

As shown in fig. 1 and 4, a greenhouse limiting device comprises a first limiting device 1 and a second limiting device 2, wherein the two limiting devices are respectively fixedly connected with a resistance chassis 4 into a whole through a fixed vertical rod 3, the resistance chassis 4 is provided with a certain inclination and is installed below the ground to fix the whole limiting device, and after the installation is completed, the first limiting device 1 and the second limiting device 2 are located on the same horizontal straight line and are different in height.

Specifically, the telescopic rod structure for fixing the upright rod 3 comprises a bottom fixing section and a top telescopic section, the bottom of the telescopic section penetrates into a central hole of the fixing section, a plurality of positioning holes which can be overlapped are formed in the side walls of the bottom fixing section and the top telescopic section, and the positioning nails are inserted into the two overlapped positioning holes to adjust and position the height of the telescopic rod structure, so that the greenhouse with different sizes can be conveniently installed and used; the rolling machine 5 is hinged with a first cantilever rod 601, the first cantilever rod 601 is hinged with a second cantilever rod 602 and can form a certain included angle in the same horizontal plane, the cantilever rod 602 is hinged with the ground to fix the whole rolling machine device, the rolling machine 5 drives the first cantilever rod 601 to move after being started, and then the second cantilever rod 602 also starts to move; the probes of the first limiting stopper and the second limiting stopper are protected by rain and snow, and the fixed vertical rod 3 is made of a galvanized material which is sprayed with plastics, so that rusting is prevented.

Furthermore, the 1 st part of the controller of the utility model is an AC contactor part which controls the power parts of the rolling and releasing of the curtain rolling machine; the 2 nd part is a secondary relay control part for controlling the driving end of the alternating current contactor; the 3 rd part is a limiter part, and the limiter is provided with a normally closed contact.

The action process of the utility model is as follows:

first, as shown in fig. 1, fig. 2 and fig. 4, the utility model discloses a first embodiment, curtain machine corotation drives the heat preservation curtain upward movement, and first cantilever bar 601 moves along with curtain machine and drives second cantilever bar 602 then, and when the last limiting position of curtain machine arrival warmhouse booth, second cantilever bar 602 touches first limiting sensor 1's contact, and simultaneously, first limiting sensor 1's K1 contact disconnection, curtain machine power is disconnected, and curtain machine stop work is rolled up.

Like fig. 1, fig. 3 and fig. 4 the utility model discloses a second embodiment, curtain machine reversal drive heat preservation curtain downstream, first cantilever bar 601 moves along with rolling up the curtain machine and then drives second cantilever bar 602, and when rolling up the lower stop position that the curtain machine reachd the warmhouse booth, second cantilever bar 602 touches second stop sensor 2's contact, and simultaneously, second stop sensor's normally closed contact K1 disconnection, rolls up curtain machine power and is broken off, rolls up curtain machine stop work.

The operation principle is as follows: normally, the stop is not triggered, K1 is in normally closed state, and the power supply can energize the 2 nd part relay coil through normally closed contact K1. K2 pulls in, thereby supplying power to the drive coil of the 3 rd part AC contactor. K3, the rolling machine executes the rolling or releasing action. When the limiting stopper is triggered, the K1 is changed from a normally closed point to a normally open point, then the K2 is disconnected, and the K3 is disconnected. Prevent the rolling or unrolling of the curtain rolling machine.
