Description

Technical Field

[0001] The present application relates to the technical field of greenhouses, and in particular to a windproof and anti-falloff structure for an external sunshade curtain of a greenhouse. Background Art

[0002] With the development of modern agricultural technology, greenhouses have become an indispensable part of agricultural production. By controlling the internal environment, greenhouses have achieved off-season planting and year-round supply of crops. In the use of greenhouses, external sunshades play a vital role. They can not only block strong light, lower the temperature inside the greenhouse, and protect crops from strong light burns, but also reduce energy consumption to a certain extent and improve crop yield and quality.

[0003] However, in strong winds, the existing external sunshade curtains are easily affected by the direct force of the wind, causing structural deformation or damage, thus affecting their sunshade effect and service life. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the present application provides a windproof and anti-falloff structure for the external sunshade curtain of a greenhouse, which has the advantages of being windproof and anti-flipping, and solves the problem that the existing external sunshade curtain is easily affected by the direct effect of wind in strong wind weather, causing structural deformation or damage, affecting its shading effect and service life.

[0005] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a windproof and anti-detachment structure for sunshades outside a greenhouse, comprising a frame and a movable plate, wherein slide grooves are provided on both sides of the inner wall of the frame, and tooth plates are fixedly connected at the upper and lower ends of the slide grooves, and a plurality of curtain pressure lines arranged in a linear array are fixedly connected to the upper end of the inner wall of the frame, an air guide block is fixedly connected to one side of the upper end of the movable plate, a servo motor is fixedly connected to both sides of the upper end of the movable plate, and the output ends of the two servo motors are fixedly connected to gears, and the end of the upper end of the movable plate away from the air guide block is fixedly connected to a vertical plate, and a plurality of connecting buckles distributed in a linear manner are fixedly connected to one side of the vertical plate.

[0006] Through the above scheme, the sliding grooves on both sides of the inner wall of the frame and the tooth plate design at the upper and lower ends of the interior provide a stable sliding track and precise positioning mechanism for the movable plate. The servo motor engages with the tooth plate through the gears, which can accurately control the up and down movement of the movable plate in the sliding groove, ensuring that the unfolding and folding process of the sunshade is smooth and accurate. The design of the wind guide block effectively guides the wind force, reduces the direct impact of the wind on the sunshade, thereby reducing the risk of the sunshade falling off due to excessive wind force. At the same time, the setting of the vertical plate and the connecting buckle further enhances the stability of the sunshade, and can keep the sunshade firmly connected even in strong wind weather. Multiple pressure lines arranged in a linear array play a role in assisting in fixing the sunshade. In strong wind weather, the sunshade is pressed and held by the pressure lines, making it smoother and improving the sunshade effect.

[0007] Furthermore, a winding box is fixedly connected to the upper end of the frame, a winding roller is rotatably connected inside the winding box, two rotating seats arranged in a mirror-image distribution are fixedly connected to one side of the inner wall of the winding box, and a guide roller is rotatably connected between the two rotating seats.

[0008] Through the above scheme, the winding roller connected in rotation inside the winding box provides storage space for the winding and unfolding of the sunshade. Through the connection between the driving device and the winding roller, the automatic winding and unfolding of the sunshade can be realized, which greatly improves the management efficiency of the sunshade and reduces the complexity of manual operation.

[0009] Furthermore, a sunshade curtain is fixedly connected to the outer wall of the winding roller, and one end of the sunshade curtain away from the winding roller is fixedly arranged inside the connecting buckle.

[0010] Through the above scheme, the fixed connection between the winding roller and the sunshade curtain, and the fixed setting of the sunshade curtain away from the winding roller and the connecting buckle realize the automatic unfolding and folding of the sunshade curtain. The servo motor drives the moving plate to move horizontally, and the sunshade curtain can be easily rolled up or lowered in conjunction with the winding roller, thereby realizing precise control of the lighting conditions in the greenhouse.

[0011] Furthermore, one side of the bottom end of the rack is fixedly connected to two first legs arranged in a mirror image distribution, and one end of the bottom end of the rack away from the first legs is fixedly connected to two second legs arranged in a mirror image distribution.

[0012] Through the above solution, the first leg and the second leg design at the bottom of the frame provide stable support for the entire structure. This four-point support method can evenly distribute the weight of the frame and the external force it is subjected to, thereby improving the overall stability of the structure. Especially in strong winds or severe weather conditions, this design can effectively prevent the frame from shaking and tilting, ensuring the normal operation and safe use of the sunshade.

[0013] Furthermore, an oblique cable is fixedly connected between the two first legs and the second legs.

[0014] Through the above solution, the design of the diagonal cable forms an additional support structure between the two first legs and the two second legs. This triangular stable structure greatly enhances the anti-overturning ability of the entire frame. Even in severe weather conditions such as strong winds and heavy rain, the diagonal cable can effectively prevent the frame from shaking and tilting, ensuring the safety and stability of the sunshade system.

[0015] Furthermore, the bottom ends of the two first legs and the second legs are fixedly connected to a mounting plate.

[0016] Through the above solution, the design of the mounting plate enables the first leg and the second leg to be more conveniently connected to the top of the greenhouse or other fixed structures.

[0017] Furthermore, a solar panel is fixedly connected to the upper end of the winding box.

[0018] Through this solution, solar panels can capture and utilize sunlight energy, converting it into electricity. This design allows the sunshade system to operate without relying on external power, reducing energy consumption and operating costs, while also reducing pollution to the environment.

[0019] Furthermore, both of the gears are meshed with the toothed plate.

[0020] Through the above scheme, the meshing design of the two gears and the tooth plate makes the unfolding and folding of the sunshade smoother and faster. The gear transmission has the advantages of large torque transmission, high efficiency and smooth operation, which can ensure that the sunshade responds quickly when needed and improves the shading effect.

[0021] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0022] The windproof and anti-detachment structure of the sunshade outside the greenhouse provides a stable sliding track and precise positioning mechanism for the movable plate through the slide grooves on both sides of the inner wall of the frame and the tooth plate design at the upper and lower ends of the interior. The servo motor is engaged with the tooth plate through the gears, which can accurately control the up and down movement of the movable plate in the slide groove, ensuring that the unfolding and folding process of the sunshade is smooth and accurate. The design of the wind guide block effectively guides the wind force, reduces the direct impact of the wind on the sunshade, and thus reduces the risk of the sunshade falling off due to excessive wind force. At the same time, the setting of the vertical plate and the connecting buckle further enhances the stability of the sunshade, and can keep the sunshade firmly connected even in strong wind weather. Multiple curtain pressure lines arranged in a linear array play a role in assisting in fixing the sunshade. In strong wind weather, the sunshade is pressed and held by the curtain pressure lines, making it flatter and improving the sunshade effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] It should be noted that the frame 1, the gear plate 3, the gear 8, the first leg 16 and the second leg 17 are hot-dip galvanized to improve the rust and corrosion resistance.

[0035] The working principle of the above embodiment is:

[0036] First, the sunshade 15 is wound on the winding roller 12 and stored in the winding box 11. The movable plate 5 is located at the top of the chute 2. At this time, the gear 8 is in meshing state with the tooth plate 3, but has not yet started to move. When the sunshade 15 needs to be unfolded, the servo motor 7 is started, and the output shaft of the servo motor 7 drives the gear 8 to rotate. Since the gear 8 is meshed with the tooth plate 3, the movable plate 5 will move along the chute 2. As the movable plate 5 moves, the connecting buckle 10 gradually straightens the sunshade 15, so that it is unfolded from the winding roller 12 and covers the outside of the greenhouse. At the same time, the wind guide block 6 guides the wind, reduces the direct impact of the wind on the sunshade curtain 15, and reduces the risk of the sunshade curtain 15 falling off. When the sunshade curtain 15 is fully unfolded, the pressure line 4 presses the sunshade curtain 15 on the outside of the greenhouse, making it flatter and improving the shading effect. When the sunshade curtain 15 needs to be retracted, the servo motor 7 is started again, the servo motor 7 reverses, driving the gear 8 to rotate in the opposite direction, and the movable plate 5 moves in the opposite direction along the slide groove 2. As the movable plate 5 moves, the connecting buckle 10 releases the sunshade curtain 15, so that it is rewound on the winding roller 12.
