Description

Technical Field

[0001] This utility model relates to the field of light-transmitting panel technology, and in particular to a device for adjusting the angle of a greenhouse light-transmitting panel. Background Technology

[0002] Greenhouses, as a crucial component of modern agricultural facilities, directly impact the growth environment and yield of crops through their design and construction. Light-transmitting panels, a key component of greenhouses, primarily function to allow natural light into the greenhouse, providing crops with the necessary illumination for photosynthesis. However, due to differences in geographical location, seasonal variations, and weather conditions, greenhouses have varying light requirements at different times and seasons. Traditional greenhouse light-transmitting panels are often fixed in place, making angle adjustment impossible according to light needs. This results in uneven light intensity distribution; excessive sunlight in some areas can scorch crops, while insufficient sunlight in others hinders normal growth. While some adjustable-angle light-transmitting panel devices have emerged, these devices are mostly complex in structure, cumbersome to operate, and have limited adjustment ranges, making it difficult to meet the adjustment needs under different light conditions.

[0003] Chinese utility model patent application CN109601204A discloses a self-adjusting angle greenhouse wall heat-collecting light-collecting panel, comprising a fixing plate, a circular mounting groove on the top of the fixing plate, a vertically arranged motor mounted on the inner wall of the mounting groove, and a horizontally arranged support plate connected to the output end of the motor. Vertically arranged positioning rods are welded to both ends of the bottom of the support plate, and the positioning rods are slidably connected to the top of the fixing plate. A connecting plate is hinged to one end of the top of the support plate, and a light-collecting panel is adhered to the top of the connecting plate. A connecting rod is hinged to the bottom of the connecting plate at the end away from the hinge, and an adjusting cylinder is movably sleeved on the outer ring of the bottom end of the connecting rod. This invention enables the light-collecting panel to spontaneously adjust its light-facing surface according to the direction of sunlight, thereby better receiving light energy. Simultaneously, it can adjust the tilt angle of the light-collecting panel according to the light illumination angle in different regions, improving the light reception efficiency.

[0004] However, in the above-mentioned device, when adjusting the light-collecting panel, the position of the hinge between the light-collecting panel and the connecting rod cannot be adjusted adaptively, which makes it impossible to change the tilt angle of the light-collecting panel.

[0005] To address this, a device for adjusting the angle of greenhouse light-transmitting panels is proposed. Utility Model Content

[0006] The purpose of this invention is to provide a device for adjusting the angle of greenhouse light-transmitting panels to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a greenhouse light-transmitting panel angle adjustment device, comprising a base, characterized in that two sets of main support components are vertically fixed to the upper end of the base, and two sets of secondary support components are symmetrically and parallelly arranged on both sides of the main support components. One end of each main support component is fixedly connected to the middle of a secondary support component. A light-transmitting panel is rotatably connected to the upper end of each main support component, and the lower end of the light-transmitting panel is slidably connected to the upper end of each secondary support component. When the upper end of the secondary support component moves up and down, the light-transmitting panel flips up and down, adjusting the tilt angle of the light-transmitting panel. When the main support component moves up and down, it drives the secondary support components to move up and down synchronously, driving the entire light-transmitting panel to move up and down, adjusting the height of the light-transmitting panel.

[0008] The main support component is equipped with an auxiliary component for buffering the light-transmitting panel. The auxiliary component is in contact with the light-transmitting panel. When the wind force is too strong, the auxiliary component drives the upper part of the light-transmitting panel to move downward, reducing the tilt angle of the light-transmitting panel and reducing the wind force on the light-transmitting panel.

[0009] Preferably, the main support assembly includes two main support rods. The lower end of each main support rod is fixed to the base with bolts. A height adjustment module is fixed on each main support rod. A first lifting rod is vertically slidably connected to the upper end of each main support rod. The upper end of the first lifting rod is fixedly connected to the top plate. The light-transmitting panel is rotatably connected to the lower end of the top plate.

[0010] Preferably, the secondary support assembly includes a secondary support rod, the lower end of which is fixed to the base with bolts, the upper end of which is vertically slidably connected to a second lifting rod, the upper end of which is vertically slidably connected to a third lifting rod, the upper end of which is slidably connected to the light-transmitting panel, and an angle adjustment module is fixed on the third lifting rod.

[0011] Preferably, the first lifting rod is fixedly connected to both sides of the first lifting rod, and both ends of the first lifting rod are fixedly connected to the second lifting rod. The two sets of the third lifting rod located on the same side of the main support rod are fixedly connected by the second lifting rod. The second lifting rod is parallel to the direction of the top plate, and the second lifting rods are fixedly connected to each other by the third lifting rod. The third lifting rod is perpendicular to the direction of the top plate.

[0012] Preferably, a sliding groove is provided on the back of the light-transmitting panel on one side of the third lifting rod, the upper end of the third lifting rod is slidably connected to the sliding groove, a guide groove is provided on the side wall of the sliding groove, and a guide rod is horizontally fixed at the upper end of the third lifting rod, the guide rod being slidably connected to the guide groove.

[0013] Preferably, the lower end of the top plate is provided with a rotating groove along the direction of the top plate, and buffer grooves are vertically provided in the side walls at both ends of the rotating groove. A slider is slidably connected in the buffer groove, and the slider is elastically connected to the bottom end of the buffer groove. A first rotating rod is fixedly connected between the sliders, and the upper end of the light-transmitting plate is rotatably connected to the first rotating rod.

[0014] Preferably, the auxiliary component includes a second rotating rod connected to the upper end of the top plate. Both ends of the second rotating rod extend into the inner wall of the upper end of the top plate along the direction of the top plate. A wind-facing plate is fixed on the second rotating rod. Cams are fixed at both ends of the second rotating rod. A pressure plate is contacted and connected to the lower end of the cam. The pressure plate has an inverted U-shaped structure. The lower end of the pressure plate passes through the upper end of the rotating groove. The lower end of the pressure plate is in contact with the first rotating rod.

[0015] The beneficial effects of this utility model are:

[0016] This invention features a sliding groove and a guide groove on the back of the light-transmitting panel. The third lifting rod is slidably connected to the sliding groove, and the guide rod is slidably connected to the guide groove. When adjusting the tilt angle of the light-transmitting panel, the guide rod slides within the guide groove, ensuring the smooth rotation of the light-transmitting panel. The height of the light-transmitting panel can be adjusted using the first lifting rod, making it suitable for greenhouses under different crop conditions. Furthermore, the overall stability is improved by connecting and fixing the first, second, and third connecting rods.

[0017] When the wind is strong, the windward plate rotates, which drives the cam to rotate. The long shaft of the cam drives the pressure plate to press down on the first rotating rod, which reduces the tilt angle of the skylight and reduces the wind force on the skylight. The second rotating rod drives the slider to slide down. Under the reaction force of the spring, the slider presses down on the bottom of the top plate, making the connection between the main support rod and the base more stable. This prevents the bolts of the main support rod and the secondary support rod from loosening due to excessive wind force, which could lead to the collapse of the whole structure.

[0030] like Figures 1 to 8 As shown in the specific embodiment of this utility model, a greenhouse light-transmitting panel angle adjustment device is provided, including a base 1. Two sets of main support components are vertically fixed on the upper end of the base 1. Two sets of auxiliary support components are symmetrically and parallelly arranged on both sides of the main support components. One end of the main support component is fixedly connected to the middle of the auxiliary support component. A light-transmitting panel 5 is rotatably connected to the upper end of the main support component. The lower end of the light-transmitting panel 5 is slidably connected to the upper end of the auxiliary support component. When the upper end of the auxiliary support component moves up and down, the light-transmitting panel 5 flips up and down, adjusting the tilt angle of the light-transmitting panel 5. When the main support component moves up and down, it drives the auxiliary support component to move up and down synchronously, driving the light-transmitting panel 5 to move up and down as a whole, adjusting the height of the light-transmitting panel 5. An auxiliary component for buffering the light-transmitting panel 5 is provided on the upper end of the main support component. The auxiliary component is in contact with the light-transmitting panel 5. When the wind force is too strong, the auxiliary component drives the upper end of the light-transmitting panel 5 to move downward, reducing the tilt angle of the light-transmitting panel 5 and reducing the wind force on the light-transmitting panel 5.

[0031] As one embodiment of this utility model, such as Figures 1-4 , Figure 6 As shown, the main support assembly includes two main support rods 2. The lower end of the main support rod 2 is fixed to the base 1 with bolts. A height adjustment module 203 is fixed on the main support rod 2. The upper end of each main support rod 2 is vertically slidably connected to a first lifting rod 201. The upper end of the first lifting rod 201 is fixedly connected to the top plate 4. The light-transmitting panel 5 is rotatably connected to the lower end of the top plate 4.

[0032] As one embodiment of this utility model, such as Figures 1-5 , Figure 7As shown, the secondary support assembly includes a secondary support rod 3. The lower end of the secondary support rod 3 is fixed to the base 1 with bolts. The upper end of the secondary support rod 3 is vertically slidably connected to a second lifting rod 301.

The upper end of the third lifting rod 302 is slidably connected to the light-collecting panel 5. An angle adjustment module 306 is fixed on the third lifting rod 302. When the third lifting rod 302 moves up and down, it drives the light-collecting panel 5 to flip up and down, adjust the tilt angle of the light-collecting panel 5, and improve the lighting quality.

[0033] As one embodiment of this utility model, such as Figures 1-4 , Figure 7 As shown, the first lifting rod 201 has a first connecting rod 202 fixedly connected to both sides. Both ends of the first connecting rod 202 are fixedly connected to the second lifting rod 301. When the first lifting rod 201 moves up and down, it drives the second lifting rod 301 to move up and down synchronously, driving the light-collecting panel 5 to move up and down as a whole, adjusting the height of the light-collecting panel 5. This is suitable for greenhouses under different crop conditions. The two sets of the third lifting rod 302 located on the same side of the main support rod 2 are fixedly connected by the second connecting rod 304. The second connecting rod 304 is parallel to the direction of the top plate 4. The second connecting rod 304 is fixedly connected to each other by the third connecting rod 305. The third connecting rod 305 is perpendicular to the direction of the top plate 4. The connection and fixation of the first connecting rod 202, the second connecting rod 304 and the third connecting rod 305 improves the overall stability.

[0034] As one embodiment of this utility model, such as Figures 1-5 As shown, a sliding groove 501 is provided on the back of the light-transmitting panel 5 on one side of the third lifting rod 302. The upper end of the third lifting rod 302 is slidably connected to the sliding groove 501. A guide groove 502 is provided on the side wall of the sliding groove 501. A guide rod 303 is horizontally fixed at the upper end of the third lifting rod 302. The guide rod 303 is slidably connected to the guide groove 502. When the third lifting rod 302 moves up and down, the guide rod 303 slides in the guide groove 502, and the light-transmitting panel 5 flips up and down.

[0035] As one embodiment of this utility model, such as Figures 1-4 , Figures 6-8 As shown, a rotating groove 401 along the direction of the top plate 4 is provided at the lower end of the top plate 4. Buffer grooves 406 are vertically provided in the side walls at both ends of the rotating groove 401. A slider 407 is slidably connected in the buffer groove 406. The slider 407 is elastically connected to the bottom end of the buffer groove 406. A first rotating rod 402 is fixedly connected between the sliders 407. The upper end of the light-transmitting plate 5 is rotatably connected to the first rotating rod 402.

[0036] As one embodiment of this utility model, such as Figures 1-2 , Figures 6-8As shown, the auxiliary component includes a second rotating rod 403, which is connected to the upper end of the top plate 4. Both ends of the second rotating rod 403 extend into the inner wall of the upper end of the top plate 4 along the direction of the top plate 4. A wind-facing plate 6 is fixed on the second rotating rod 403. Cams 404 are fixed to both ends of the second rotating rod 403. A pressure plate 405 is contacted and connected to the lower end of the cam 404. The pressure plate 405 has an inverted U-shaped structure. The lower end of the pressure plate 405 passes through the upper end of the rotating groove 401. The lower end of the pressure plate 405 is in contact with the first rotating rod 402.

[0037] In actual use, initially, the windward plate 6 is vertical, the long axis of the cam 404 is horizontal, and the first rotating rod 402 is located at the upper end of the rotating groove 401 under the action of the spring. When the wind force is large, the windward plate 6 rotates, which drives the cam 404 to rotate. The long axis of the cam 404 drives the pressure plate 405 to press down on the first rotating rod 402, which makes the tilt angle of the skylight 5 smaller and reduces the wind force on the skylight 5. At this time, the guide rod 303 slides upward relative to the guide groove 502, so that the skylight 5 can be flipped smoothly. At the same time, the first rotating rod 402 drives the slider 407 to slide downward and squeeze the spring. Under the reaction force of the spring, the slider 407 presses down on the bottom end of the top plate 4, which makes the connection between the main support rod 2 and the base 1 more stable and prevents the bolts of the main support rod 2 and the auxiliary support rod 3 from loosening due to excessive wind force, which would cause the whole to collapse.

[0038] Working principle: In the initial state, the windward plate 6 is vertical, the long shaft of the cam 404 is horizontal, and the first rotating rod 402 is located at the upper end of the rotating groove 401 under the action of the spring. When it is necessary to adjust the angle of the lighting panel 5, the angle adjustment module 306 is activated, causing the third lifting rod 302 to move up and down, driving the lighting panel 5 to flip up and down, adjusting the tilt angle of the lighting panel 5, and improving the lighting quality. When it is necessary to adjust the overall height of the lighting panel 5, the height adjustment module 203 is activated, causing the first lifting rod 201 to move up and down, driving the second lifting rod 301 to move up and down synchronously, driving the lighting panel 5 to move up and down as a whole. The height of the light-transmitting panel 5 is suitable for greenhouses under different crop conditions. When the wind is strong, the windward panel 6 rotates, which drives the cam 404 to rotate, causing the pressure plate 405 to press down on the first rotating rod 402, making the tilt angle of the light-transmitting panel 5 smaller and reducing the wind force on the light-transmitting panel 5. At the same time, the first rotating rod 402 drives the slider 407 to slide down. Under the reaction force of the spring, the slider 407 presses down on the bottom end of the top plate 4, making the connection between the main support rod 2 and the base 1 more stable, preventing the bolts of the main support rod 2 and the secondary support rod 3 from loosening due to excessive wind force, which could lead to the collapse of the whole structure.
