When extreme weather such as a typhoon is approaching, the servo motor 10 is started to drive the threaded sleeve 7 to rotate. Since the first screw 8 is threadedly connected to the threaded sleeve 7, the rotation of the threaded sleeve 7 will drive the first screw 8 to move up and down. At this time, the movement of the first screw 8 will further drive the support tube 3 and the top frame 5 to rise and fall together, thereby reducing the overall height of the greenhouse. By lowering the height, the lateral wind pressure and impact force on the greenhouse can be reduced, the stability and bearing capacity of the structure can be improved, and the height of the greenhouse can be adjusted according to different weather conditions and actual needs, thereby improving the adaptability and safety of the greenhouse.

[0032] See also Figure 1-Figure 7, multiple groups of connecting parts 11 are fixed to one side of the outer wall of the support tube 3, and the multiple groups of connecting parts 11 are slidably connected to the reinforcing rods 12; screw holes are correspondingly opened in the connecting parts 11 and the reinforcing rods 12; one end of the reinforcing rod 12 is threaded, and the threaded end of the reinforcing rod 12 is provided with a nut 13; one end of the reinforcing rod 12 is fixed to a limit block 14; when working, the connecting parts 11 are fixed to one side of the outer wall of the support tube 3, and the number can be set to multiple groups according to design requirements to evenly distribute and enhance the support effect, which serves as the sliding track and fixed point of the reinforcing rod 12 to ensure that the reinforcing rod 12 can slide stably and be fixed along the predetermined path At the desired position, during the installation or adjustment of the cross-frame structure, an appropriate number of reinforcing rods 12 are selected as needed and slid into the connecting piece 11. By rotating the nut 13, the reinforcing rod 12 is fastened to the desired position.

At this time, the movement of the first screw 8 will further drive the support tube 3 and the top frame 5 to rise and fall together, thereby lowering the overall height of the greenhouse. By lowering the height, the lateral wind pressure and impact force on the greenhouse can be reduced, the stability and bearing capacity of the structure can be improved, and the height of the greenhouse can be adjusted according to different weather conditions and actual needs, thereby improving the adaptability and safety of the greenhouse; the connecting piece 11 is fixedly connected to one side of the outer wall of the support tube 3, and the number can be set to multiple groups according to design requirements to evenly distribute and enhance the support effect The reinforcement rod 12 is used as a sliding track and fixing point for the reinforcement rod 12, ensuring that the reinforcement rod 12 can slide stably along the predetermined path and be fixed in the desired position. During the installation or adjustment of the cross-frame structure, an appropriate number of reinforcement rods 12 are selected as needed and slidably inserted into the connector 11. The reinforcement rod 12 is fastened to the desired position by rotating the nut 13. The presence of the limit block 14 ensures that the reinforcement rod 12 will not accidentally slide out of the connector 11. In addition, if it is necessary to further enhance the stability of the connection, the reinforcement rod 12 and the connector 11 can be further fixed together by screws. By introducing components such as the reinforcement rod 12 and the connector 11, the stability and load-bearing capacity of the cross-frame structure are significantly enhanced. , which improves the wind resistance of the greenhouse under extreme weather conditions; the interior of the support rod 2 and the top frame 5 are both hollow, which reduces the overall weight of the structure and provides sufficient space to accommodate other components or perform necessary structural reinforcement. At the same time, the first gasket 15 and the second gasket 16 form a triangular support structure inside the cavity, so that the frame can effectively disperse and resist external forces when they act, thereby increasing the overall stability of the structure; by rotating the second screw 20, the position of the clamping plate 19 inside the bracket 18 can be adjusted, and the bracket 18 can be used to clamp the greenhouse cloth, and the clamping force and position of the clamping plate 19 can be adjusted to adapt to greenhouse cloths of different thicknesses and materials, thereby improving applicability;The 90-degree angle formed between the first gasket 15 and the second gasket 16 enhances the stability of the supporting structure. When the top frame 5 is subjected to external forces, this angle design can more effectively disperse and resist these forces, thereby preventing the structure from tilting or collapsing. When the base plate is placed on the ground, the thorn plates 21 can penetrate the soil or ground material, thereby increasing the contact area and friction between the base plate 1 and the ground, reducing the movement of the base plate 1 under wind, rain or other external forces.
