[0018] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other.
[0019] like Figures 1 to 3 In the embodiment of the photovoltaic agricultural greenhouse of the present invention shown, the photovoltaic agricultural greenhouse includes a photovoltaic panel 1 and a lightweight bracket 2. The bracket 2 is an oblique bracket 2 composed of two side panels 21 and an end plate 22 fixedly connected. One end of the photovoltaic panel 1 is hinged to the lower end of the two side panels 21 of the bracket 2, and the other end of the photovoltaic panel 1 is supported on the bracket 2. A slide groove 3 is provided on the two side panels 21 of the bracket 2, and a sliding shaft 4 is slidingly connected in the slide groove 3. A traction rope 5 is fixedly connected to the sliding shaft 4. A rope winder 6 for winding the traction rope 5 is fixedly connected to the end plate 22 of the bracket 2. The two ends of the sliding shaft 4 are rotatably connected to the support rod 7, and the other end of the support rod 7 is hinged to the photovoltaic panel 1.
[0020] Specifically, when the sunlight angle is low in winter, it is necessary to adjust the angle of the photovoltaic panel 1 to adapt to the sunlight angle, so that the rope winder 6 rotates to wind the traction rope 5, and the traction rope 5 pulls the slide shaft 4 to move in the slide groove 3. The support rod 7 is affected by the movement of the slide shaft 4 and gradually lifts the photovoltaic panel 1, so that the photovoltaic panel 1 rotates around the hinge part at the lower end to adjust the angle of the photovoltaic panel 1. When the angle of the photovoltaic panel 1 needs to be lowered, the rope winder 6 is rotated in the opposite direction. Under the action of the weight of the photovoltaic panel 1, the support rod 7 pushes the slide shaft 4 to move downward in the slide groove 3 until the slide shaft 4 moves to the lowest end of the slide groove 3. The mechanism of adjusting the angle of the photovoltaic panel 1 of this device is simple and light in weight. Combined with the lightweight photovoltaic panel bracket, the cost of greenhouse construction is reduced and the economic benefits of agricultural greenhouses are improved.
[0021] In one embodiment of the present application, preferably, a rail groove 8 is fixedly connected to the inner side of the side panel 21, a sliding wheel 9 slides in the rail groove 8, and the sliding wheel 9 is rotatably connected to the sliding shaft 4, so that the sliding shaft 4 moves more smoothly in the sliding groove 3, thereby reducing the load on the rope winder 6.
[0022] In one embodiment of the present application, preferably, a fixed shaft 10 is fixedly connected to the photovoltaic panel 1, and an axial hole 11 is provided on the support rod 7. The fixed shaft 10 is rotatably connected to the axial hole 11 to enable the support rod 7 to support the photovoltaic panel 1.
[0023] In one embodiment of the present application, preferably, the angle between the support rod 7 and the photovoltaic panel 1 is always an acute angle, so as to avoid forming a triangular stability when the support rod 7 moves with the sliding shaft 4 to the photovoltaic panel 1 at a right angle or an obtuse angle. When adjusting the angle downward, the weight of the photovoltaic panel 1 cannot cause the support rod 7 to push the sliding shaft 4 to slide downward, so that the angle of the photovoltaic panel 1 cannot be adjusted down.
[0024] In one embodiment of the present application, preferably, the rope winder 6 includes a support 61 and a winding shaft 62, the support 61 is fixedly connected to the end plate 22, the winding shaft 62 is rotatably connected to the support 61, and a rope hole 12 through which the traction rope 5 passes is provided on the end plate 22, which is used to wind or loosen the traction rope 5 when the winding shaft 62 rotates.
[0025] In one embodiment of the present application, preferably, a motor 13 is fixedly connected to the bracket 2 , and a driving shaft of the motor 13 is fixedly connected to the winding shaft 62 for driving the winding shaft 62 to rotate.
[0026] In one embodiment of the present application, preferably, a reflective film is applied to the bottom of the photovoltaic panel 1 (not shown in the figure). The season for adjusting the angle of the photovoltaic panel 1 is mostly winter. The light in the greenhouse is weak in winter. The radiant reflective film can increase the light in the greenhouse. When artificial lighting is used in the greenhouse, the reflective film can reduce light escape, thereby achieving energy-saving effect.
[0027] To sum up, the photovoltaic agricultural greenhouse in the above embodiment of the present invention, specifically, fixes the lightweight bracket 2 on the top of the agricultural greenhouse frame. When the angle between the photovoltaic panel 1 and the bracket 2 needs to be increased, the motor 13 is started to drive the winding shaft 62 to rotate, and the traction rope 5 is pulled to make the sliding shaft 4 move along the slide groove 3 toward the end plate 22. When moving, the support rod 7 is pushed to lift the photovoltaic panel 1 until the photovoltaic panel 1 is adjusted to the required angle. When the angle is lowered, the motor 13 is rotated in the opposite direction to loosen the traction rope 5. Under the action of the gravity of the photovoltaic panel 1, the support rod 7 pushes the sliding shaft 4 to slide along the slide groove 3 toward the hinged position of the photovoltaic panel 1, so that the photovoltaic panel 1 is gradually lowered; this device can be used to make modular devices for arrangement and connection, and a single motor drives a multi-device rope winder; the mechanism of adjusting the angle of the photovoltaic panel 1 of this device is simple and light in weight. Combined with the lightweight photovoltaic panel bracket, the greenhouse construction cost is reduced and the economic benefits of the agricultural greenhouse are improved.
[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
