[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0022] See also Figure 1-4 A sunshade device for a greenhouse comprises a support frame 1, a top frame 2 and a sunshade curtain 4. The support frame 1 is provided with multiple groups, and the top of the multiple groups of support frames 1 is fixedly provided with a top frame 2, and the top frame 2 is provided with a sunshade opening. Two groups of fixed frames 9 are fixedly provided on the front side of the top of the top frame 2, and the two groups of fixed frames 9 are distributed left and right. A screw 11 is rotatably provided between the two groups of fixed frames 9, and a driving motor 10 is fixedly provided on one side of the fixed frame 9, and the output end of the driving motor 10 is connected to the screw 11. A moving seat 5 is slidingly provided on the top of the top frame 2, and the moving seat 5 is threadedly connected to the screw 11. A sunshade curtain 4 is fixedly provided between the right inner wall of the sunshade opening and the moving seat 5, and the sunshade curtain 4 is a folding structure.

[0023] The driving motor 10 drives the screw 11 to rotate, and drives the moving seat 5 to move on the top of the top frame 2 through the thread. When the moving seat 5 moves, it will drive the sunshade 4 to move in the sunshade opening. When the moving seat 5 moves to the left, the sunshade 4 will be flattened, so that it can be effectively done. When the moving seat 5 moves to the right, the sunshade 4 can be folded up. It should be noted that the support frame 1 needs to be located at the four corners of the greenhouse, and the top frame 2 is located on the upper side of the greenhouse. This structure is simple to operate and highly practical.

[0024] The above structure has the problem that the sunshade curtain 4 is prone to falling when in use. In order to solve the above problem, multiple groups of guide rods 3 are fixedly provided on the left and right inner walls of the sunshade opening, and guide holes are provided on the sunshade curtain 4. The guide rods 3 pass through the guide holes. When the movable seat 5 moves the sunshade curtain 4, the sunshade curtain 4 moves on the guide rods 3 through the guide holes, so that the sunshade curtain 4 will not fall in the sunshade opening.

[0025] The above-mentioned moving seat 5 needs to have good stability when moving. In order to meet the above requirements, a guide column 6 is fixedly provided on the rear side of the top of the top frame 2, and a guide hole 2 is provided on one side of the moving seat 5. The guide column 6 passes through the guide hole 2. The moving seat 5 moves on the guide column 6 through the guide hole 2, which can increase the stability of the movement.

[0026] The above structure needs to be easy to power when in use. In order to meet the above requirements, a photovoltaic panel 7 is fixedly installed on the top of the top frame 2, and an inner cavity is provided on the lower side of the photovoltaic panel 7 of the top frame 2. A battery pack is fixedly installed in the inner cavity, and the battery pack, the drive motor 10 and the photovoltaic panel 7 are electrically connected.

[0027] When the above structure is in use, there is a problem that the driving motor 10 and the screw rod 11 are easily exposed to rain. In order to solve the above problem, a rain shield 8 is fixedly provided on the top of the top frame 2 on the upper side of the driving motor 10 and the screw rod 11.

[0028] In this embodiment, the driving motor 10 is a reduction motor.
