Vegetable greenhouses usually use heating, ventilation, shading, irrigation and other equipment to protect vegetables from bad weather, extend the growing season, and improve yield and quality.

[0003] In the prior art, vegetable greenhouses are heated by solar photovoltaics. A support frame is fixed on the top of the vegetable greenhouse, and the solar photovoltaics are fixed to the support frame by bolts. In cold weather, the solar photovoltaics convert solar energy into electrical energy, which is converted into heat energy through solar collectors and transported into the greenhouse.

[0004] However, when it is a suitable season for vegetable planting, the vegetable greenhouse needs to be opened. However, the solar photovoltaic installed on the support frame has a shading effect on the sunlight, which causes the vegetables to not be fully exposed to sunlight, affecting the growth of vegetables, thereby reducing the use effect of the vegetable greenhouse. Utility Model Content

[0005] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model proposes a solar photovoltaic heating vegetable greenhouse, which solves the problem that the vegetable greenhouse needs to be opened when it is in a season suitable for vegetable planting. However, the solar photovoltaic is installed on the support frame and has a blocking effect on sunlight, which causes the vegetables to be unable to be fully exposed to sunlight, affecting the growth of vegetables, thereby reducing the use effect of the vegetable greenhouse.

[0006] To achieve the above-mentioned purpose, according to the embodiment of the first aspect of the utility model, a solar photovoltaic heating vegetable greenhouse is proposed, comprising:

[0007] A movable shaft, a plurality of rotating frames are equidistantly sleeved and connected to the two sides of the movable shaft, a sliding seat is fixedly connected to the two ends of the movable shaft, a connecting plate is fixedly connected to the bottom ends of the plurality of rotating frames, and a solar photovoltaic is bolted to the top of the rotating frame;

[0008] Support columns, wherein two groups of support columns are provided and are respectively located at the two ends of the moving shaft, the support columns are connected with the moving shaft, a slide groove is longitudinally provided inside the support columns, and a limiting groove is respectively provided at the two ends of the support columns, and the limiting groove is connected with the slide groove;

[0009] The supporting assembly is provided with two groups and is respectively fixed at two ends of the slide seat, and the supporting assembly is cooperatively connected with the rotating frame.

[0010] As a further solution of the utility model: the slide is clamped in the slide groove and is slidably connected to the inner wall of the slide groove. The slide is provided with a threaded hole in a direction parallel to the axis of the support column.

[0026] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figures 1 to 7 As shown, a solar photovoltaic heating vegetable greenhouse includes: a moving shaft 1, a supporting column 3 and a supporting assembly.

[0028] A number of rotating frames 2 are axially equidistantly sleeved and connected on both sides of the moving shaft 1, and slide seats 13 are fixedly connected to the two ends of the moving shaft 1 respectively, and the bottom ends of the several rotating frames 2 are fixedly connected to connecting plates 6, and the top of the rotating frame 2 is bolted to the solar photovoltaic 5. The moving shaft 1 is used to provide support for the rotating frame 2. The rotating frame 2 is sleeved on the moving shaft 1, and the rotating frame 2 can rotate around the moving shaft 1. The top of the rotating frame 2 is installed with bolts and solar photovoltaic 5. The specific working principle belongs to the prior art and will not be repeated here. The bottom ends of the several rotating frames 2 are formed into a whole by the fixedly connected connecting plates 6 to avoid the phenomenon of the rotating frame 2 being offset on the moving shaft 1;

[0029] There are two groups of support columns 3, which are respectively located at the two ends of the moving shaft 1. The support columns 3 are connected with the moving shaft 1. A slide groove 16 is longitudinally provided inside the support column 3. A limit groove 4 is provided at both ends of the support column 3. The limit groove 4 is connected with the slide groove 16. The support column 3 is used to provide support for the moving shaft 1. When it is in a season suitable for vegetable planting, the vegetable greenhouse is opened, and the moving shaft 1 can be lowered through the support column 3. The moving shaft 1 drives the solar photovoltaic 5 to move downward through the rotating frame 2;

[0030] There are two groups of support components and they are respectively fixed at the two ends of the slide 13. The support components are connected with the rotating frame 2. When the movable shaft 1 reaches the bottom of the support column 3, the support component is removed from the rotating frame 2. The rotating frame 2 rotates around the movable shaft 1 with the solar photovoltaic 5 until the solar photovoltaic 5 is perpendicular to the ground. Then a group of support columns 3 is removed, and then the rotating frame 2 and the solar photovoltaic 5 are removed from the movable shaft 1 as a whole, thereby avoiding the influence of the solar photovoltaic 5 on the top of the vegetable greenhouse on the vegetables, ensuring that the vegetables fully absorb sunlight.

[0031] In some specific implementation schemes, the slide 13 is clamped in the slide groove 16 and is slidably connected to the inner wall of the slide groove 16. The slide 13 is provided with a threaded hole 14 in a direction parallel to the axial center line of the support column 3. The threaded hole 14 is threadedly connected to a threaded rod 12. The bottom end of the threaded rod 12 is fixedly connected to a servo motor 9. The movable shaft 1 slides up and down along the inner wall of the slide groove 16 through the slides 13 at both ends. In order to save manpower when the movable shaft 1 slides, the servo motor 9 drives the threaded rod 12 to rotate, and the threaded rod 12 drives the slide 13 to move through the threaded connection with the threaded hole 14. The limiting effect provided by the support column 3 ensures that the slide 13 will not rotate on its own.

[0032] In some specific implementation schemes, the bottom end of the support column 3 is fixedly connected to the base plate 7, and the bottom of the base plate 7 is fixedly connected to the base columns 8 on all sides. The horizontal height of the base plate 7 is higher than the servo motor 9, and the threaded rod 12 is connected to the base plate 7. In order to prevent the weight borne by the support column 3 from acting on the servo motor 9, the bottom end of the support column 3 transfers the bearing force to the ground through the fixed base plate 7 and base column 8, wherein the base column 8 can prevent the servo motor 9 from being affected by the bearing force, and the base plate 7 can limit the slide 13 to prevent the slide 13 from sliding out of the slide groove 16 when it moves to the bottom of the support column 3, thereby causing damage to the servo motor 9. It should be noted that the base plate 7 is provided with a circular hole, and the threaded rod 12 rotates along the inner wall of the circular hole.

[0033] In some specific embodiments, the support assembly includes: a support plate 10 and a positioning column 19, the support plate 10 is fixedly connected to the side end of the slide 13, the support plate 10 is matched with the positioning column 19, and the support plate 10 is slidably connected to the inner wall of the limiting groove 4, the rotating frame 2 is provided with a positioning groove 17 along the axis of the positioning column 19, the positioning column 19 is in a rectangular shape, the positioning column 19 is slidably connected to the inner wall of the positioning groove 17, and a fixing hole 18 is provided inside the rotating frame 2 in a direction parallel to the axis of the positioning column 19, the fixing hole 18 completely penetrates the positioning column 19, and the fixing hole 18 is threaded A fixing bolt 20 is connected, and the side end of the fixing bolt 20 is abutted and connected with the support plate 10. In order for those skilled in the art to better understand the working principle of the support assembly of the utility model, when the movable shaft 1 moves to the bottom of the support column 3, the fixing bolt 20 is controlled to rotate, and the fixing bolt 20 is disengaged from the fixing hole 18. The fixing bolt 20 releases the fixing effect on the positioning column 19, and the positioning column 19 is pulled out of the positioning groove 17. The positioning column 19 releases the connection between the support plate 10 and the rotating frame 2. At the same time, the positioning column 19 releases the limiting effect on the rotating frame 2.

[0034] In some specific implementation schemes, the connecting plate 6 is parallel to the axis of the movable axis 1, and the connecting plate 6 is abutted against the bottom end of the solar photovoltaic 5. In order to further strengthen the fixing effect of the solar photovoltaic 5, the connecting plate 6 abuts against the bottom end of the solar photovoltaic 5. When the solar photovoltaic 5 rotates around the movable axis 1, the connecting plate 6 starts to support the weight of the solar photovoltaic 5, thereby reducing the force of the bolts supporting the solar photovoltaic 5.

[0035] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
