Description

Technical Field

[0001] The utility model relates to the field of glass greenhouse sunshade devices, and more specifically to an external sunshade device for a glass greenhouse. Background Art

[0002] A glass greenhouse refers to a greenhouse that uses glass as a lighting material. It is a type of greenhouse. Among cultivation facilities, the glass greenhouse has the longest service life and is suitable for use in a variety of regions and various climatic conditions. In order to meet the requirements of light collection in the glass greenhouse, shading is required on the outside of the glass in some cases. Most of the existing shading devices use artificial covering with shade cloth.

[0003] The current external sunshade device for a glass greenhouse, for example, the "External Sunshade Device for a Glass Greenhouse" proposed with patent number ZL202320958616.4, includes a long base, an axis frame, a motor, a first reducer, a rotating shaft, a rope reel, a pull rope, a sunshade cloth roller, a sunshade cloth and a constraint frame. Two groups of long bases are respectively arranged at the lower ends of the left and right sides of the glass greenhouse, and multiple groups of constraint frames are vertically connected to the top of the two groups of constraint frames. The tops of the two groups of long bases are respectively connected to the bottom ends of a group of axis frames, the front ends of the axis frames are connected to the rear ends of the first reducer, the output ends of the motor are connected to the input ends of the first reducer, the inner side of the axis frame is vertically connected with a rotating shaft, the outer wall of the left rotating shaft is connected to the inner wall of the sunshade cloth roller, and the outer side of the right rotating shaft is connected with a rope reel corresponding to the lateral position of the constraint frame, a group of pull ropes are connected and wound on the outside of each group of rope reels, and a sunshade cloth is wound and connected on the outside of the sunshade cloth roller.

[0004] The existing external sunshade device for glass greenhouses connects a pull rope to a sunshade cloth, and pulls the sunshade cloth to move by reeling or unreeling the pull rope. Although it can achieve the purpose of shading the glass greenhouse, in actual use, the sunshade cloth is unfolded when needed, and retracted when not needed. The sunshade cloth is prone to a certain degree of wear and tear during the continuous unfolding and retracting process, and the device is not easy to disassemble and replace the sunshade cloth. If the sunshade cloth is excessively worn or damaged, it is easy to affect the overall shading effect. Therefore, there is an urgent need to improve the technology of the external sunshade device structure of the glass greenhouse to improve this equipment. Utility Model Content

[0005] 1. Technical issues to be solved

[0006] In view of the problems existing in the prior art, the purpose of the utility model is to provide an external sunshade device for a glass greenhouse, which can be achieved by placing the sunshade cover between the fixed frame and the movable frame when the external sunshade device for the glass greenhouse is used, and connecting plates are fixed at both ends of the sunshade cover, and the connecting plates can drive the positioning blocks to move into the corresponding positioning grooves at the fixed frame and the movable frame. After that, the rotating rod can be rotated to drive the movable plate to move into the notch through the transmission mechanism to limit the positioning blocks, thereby achieving the purpose of installing and fixing the sunshade cover. At the same time, when the sunshade cover is over-frosted due to long-term use, the sunshade cover can be disassembled and replaced relatively easily, and the sunshade cover is a telescopic accordion cover made of rubber, which can delay the damage time of the sunshade cover to a certain extent and improve the service life of the sunshade cover.
