[0030] A lateral protection assembly is arranged on the transverse support rod 2, and the lateral protection assembly includes a lateral protection structure and a No. 1 rolling curtain 17. The lateral protection structure includes a fixed rod 8 fixedly installed on the transverse support rod 2, and a symmetrically arranged rotating sleeve 9 is rotatably installed on the fixed rod 8. A sliding groove 10 is provided on the rotating sleeve 9, and a movable frame 16 is movably installed in the rotating sleeve 9. The movable frame 16 is fixedly connected to the No. 1 rolling curtain 17, and the rotating sleeve 9 is connected to the winding assembly and the swinging assembly.

[0031] See also Figure 1-4 , Figure 7 It should be noted that the arc-shaped support rod 1 and the transverse support rod 2 are fixed to each other, and the two support rods are combined to form multiple spaces. A No. 1 roll-up curtain 17 is provided in each space to seal the internal space formed by the support rod combination. In the initial state, the No. 1 roll-up curtain 17 is in an unfolded state. Under the action of the No. 1 roll-up curtain 17, the greenhouse is sealed. When the greenhouse needs to be ventilated, the winding assembly moves, driving the movable frame 16 to move toward the rotating sleeve 9, thereby driving the No. 1 roll-up curtain 17 to move. At the same time, the winding assembly will also roll up the No. 1 roll-up curtain 17.

[0032] The lateral support rod 2 is also provided with a winding assembly connected to the lateral protection structure, and the winding assembly can drive the lateral protection structure to move and reel in the No. 1 rolling curtain 17. The winding assembly includes a fixed plate fixedly mounted on the rotating sleeve 9, a dual-axis motor 11 is fixed on the fixed plate, a transmission rod 12 connected to the output shaft of the dual-axis motor 11 is rotatably mounted on the fixed plate, a driven structure connected to the transmission rod 12 is provided on the fixed plate, and the driven structure is connected to the rotating sleeve 9 and the movable frame 16, wherein the driven structure includes a line roller 13 fixedly mounted on the transmission rod 12 and symmetrically arranged, and a line roller 13 wound on the rotating sleeve 9. The No. 2 steel wire rope 14 on the wire roller 13, the No. 2 sliding block 15 slidably mounted on the slide groove 10 and fixedly connected to the movable frame 16, the No. 1 bevel gear 22 is also fixed on the transmission rod 12, and the rotating sleeve 9 is provided with a gearing connected to the movable frame 16 and the No. 1 winding curtain 17, the gearing includes a rack plate 18 fixedly mounted on the rotating sleeve 9, a gear 19 meshing with the rack plate 18 is rotatably mounted on the movable frame 16, and a rotating rod 21 is also rotatably mounted on the movable frame 16, the rotating rod 21 is sleeved with a belt 20 connected to the rotating shaft of the gear 19, and the No. 1 winding curtain 17 is wound around the rotating rod 21.

[0033] See also Figure 1-4 , Figure 7To be more specific, in the initial state, the movable frame 16 is located at the end of the stroke away from the rotating sleeve 9. At this time, the No. 1 roll-up curtain 17 is in a released state. When the greenhouse needs to be ventilated, the dual-axis motor 11 works to drive the transmission rod 12 to rotate, thereby driving the wire roller 13 to rotate. Under the action of the wire roller 13, the No. 2 steel wire rope 14 is wound, thereby driving the No. 2 sliding block 15 to move along the length direction of the slide trough 10 through the No. 2 steel wire rope 14. The No. 2 sliding block 15 will also drive the movable frame 16 to move along the length direction of the slide trough 10, thereby driving the No. 1 roll-up curtain 17 to move, so that The No. 1 roll-up curtain 17 is in a relaxed state, and the movable frame 16 will also drive the gear 19 to move. Since the gear 19 is meshed with the rack plate 18, the gear 19 rotates under the action of the rack plate 18, thereby driving the belt 20 to move. Under the action of the belt 20, the rotating rod 21 is driven to rotate, thereby rolling up the No. 1 roll-up curtain 17 on the rotating rod 21, and ensuring that the No. 1 roll-up curtain 17 always remains in a straight state. The transmission rod 12 will also drive the No. 1 bevel gear 22 to rotate, and under the action of the swing assembly, the No. 1 bevel gear 22 cooperates with the top protection assembly, thereby driving the top protection assembly to move.

[0034] A swing assembly is arranged on the arc-shaped support rod 1 and connected to the lateral protection structure. The swing assembly can adjust the angle of the No. 1 rolling curtain 17 through the lateral protection structure and drive the winding assembly to move. The swing assembly includes a No. 1 motor 3 fixedly mounted on the arc-shaped support rod 1, a pulley rotatably mounted on the arc-shaped support rod 1 and connected to the output shaft of the No. 1 motor 3, and a No. 1 steel wire rope 4 wound on the pulley. A sliding structure connected to the No. 1 steel wire rope 4 is provided on the arc-shaped support rod 1, and the sliding structure is connected to the rotating sleeve 9, wherein the sliding structure includes a guide rail 5 fixedly mounted on the arc-shaped support rod 1, a No. 1 sliding block 6 is slidably mounted on the guide rail 5, a connecting rod 7 rotatably mounted on the No. 1 sliding block 6 and rotatably connected to the rotating sleeve 9, and the No. 1 sliding block 6 is fixedly connected to the No. 1 steel wire rope 4.

[0035] See also Figure 1-3 , Figure 5 Furthermore, when the greenhouse needs to be ventilated, the angle of the No. 1 rolling curtain 17 can be adjusted to separate the No. 1 rolling curtain 17 from the support rod. At this time, the No. 1 motor 3 works to drive the pulley to rotate, so that the No. 1 steel wire rope 4 is wound around the pulley. Under the action of the No. 1 steel wire rope 4, the No. 1 sliding block 6 is driven to move along the length direction of the guide rail 5. The No. 1 sliding block 6 will also drive the connecting rod 7 to move. Under the action of the connecting rod 7, the rotating sleeve 9 rotates around the fixed rod 8, thereby driving the No. 1 rolling curtain 17 to rotate a certain angle. The rotating sleeve 9 will also drive the No. 1 bevel gear 22 to move through the transmission rod 12, so that the No. 1 bevel gear 22 moves to a position that cooperates with the top protection component.

[0036] A top protection component is arranged on the arc-shaped support rod 1 and cooperates with the winding component. The top protection component includes a top protection structure and a No. 2 rolling curtain 30. The top protection structure can drive the No. 2 rolling curtain 30 to move after the winding component cooperates with the top protection structure. The top protection component includes a bidirectional screw rod 24 rotatably mounted on the arc-shaped support rod 1, and a No. 2 bevel gear 23 cooperating with the No. 1 bevel gear 22 is fixedly mounted on the bidirectional screw rod 24. A symmetrically arranged threaded sleeve 25 is movably mounted on the bidirectional screw rod 24. The arc-shaped support rod 1 is provided with a plurality of screw sleeves 25 disposed on the top of the bidirectional screw rod 24. A supporting structure connected to the threaded sleeve 25 is provided, and the supporting structure is connected to the No. 2 rolling curtain 30. The threaded sleeve 25 is threadedly matched with the bidirectional screw rod 24, wherein the supporting structure includes a rotating plate 27 rotatably mounted on the arc-shaped support rod 1 and symmetrically arranged, and a hinged rod 26 hinged to the rotating plate 27 is hinged on the threaded sleeve 25, and a No. 2 motor 28 is fixed on the rotating plate 27, and a winding roller 29 connected to the output shaft of the No. 2 motor 28 is rotatably mounted on the rotating plate 27, and the No. 2 rolling curtain 30 is wound around the winding roller 29.

[0037] See also Figure 1-2 , Figure 5-6 Finally, in the initial state, the No. 2 rolling curtain 30 is in the unfolded state. Under the action of the No. 2 rolling curtain 30, the top of the arc-shaped support rod 1 is sealed, and the two threaded sleeves 25 are located at the end of the stroke away from each other. At this time, the No. 1 bevel gear 22 and the No. 2 bevel gear 23 are in a separated state. When the No. 2 rolling curtain 30 needs to be rolled up, under the action of the connecting rod 7, the No. 1 bevel gear 22 moves to the meshing position with the No. 2 bevel gear 23. When the dual-axis motor 11 is working, it drives the transmission rod 12 to rotate, thereby driving the No. 1 bevel gear 22 to rotate, so that the No. 2 bevel gear 23 rotates, and the No. 2 bevel gear 23 also drives the bidirectional screw rod 24 to rotate, thereby driving the two threaded sleeves 25 toward When the two rollers 28 move in the direction of approaching each other, the threaded sleeve 25 will also drive the hinged rod 26 to move, and drive the rotating plate 27 to rotate, and move in the direction of approaching each other. Since the rotating plate 27 has a guiding function, it is ensured that the threaded sleeve 25 will not rotate with the two-way screw rod 24 during movement, and moves along the length direction of the two-way screw rod 24. When the rotating plate 27 rotates, the No. 2 roll-up curtain 30 is no longer taut. At this time, the No. 2 motor 28 works, driving the winding roller 29 to rotate, thereby winding the No. 2 roll-up curtain 30 on the winding roller 29, so that the No. 2 roll-up curtain 30 is always in a straight state. When the transmission rod 12 rotates, the No. 1 roll-up curtain 17 will also be wound up, thereby realizing the synchronous winding of the two roll-up curtains.

[0038] Taking the embodiment combining all the features recorded in the present application as an example, when in use, in the initial state, the No. 1 roll-up curtain 17 is in the unfolded state, and the No. 2 roll-up curtain 30 is in the unfolded state, thereby sealing the greenhouse. When the greenhouse needs to be ventilated, the No. 1 motor 3 works to drive the pulley to rotate, so that the No. 1 steel wire rope 4 is wound around the pulley. Under the action of the No. 1 steel wire rope 4, the No. 1 sliding block 6 is driven to move along the length direction of the guide rail 5. The No. 1 sliding block 6 also drives the connecting rod 7 to move. Under the action of the connecting rod 7, the rotating sleeve 9 rotates around the fixed rod 8, thereby driving the No. 1 roll-up curtain 17 to rotate a certain angle. The rotating sleeve 9 will also drive the No. 1 bevel gear 22 to move through the transmission rod 12, so that the No. 1 bevel gear 22 moves to the meshing position with the No. 2 bevel gear 23. At this time, the dual-axis motor 11 works to drive the transmission rod 12 to rotate, thereby driving the line roller 13 to rotate. Under the action of the line roller 13, the No. 2 steel wire rope 14 is wound, so that the No. 2 sliding block 15 is driven by the No. 2 steel wire rope 14 to move along the length direction of the slide groove 10. The No. 2 sliding block 15 will also drive the movable frame 16 to move along the length direction of the slide groove 10, thereby driving the No. 1 rolling curtain 17 to move, so that the No. 1 rolling curtain 17 is in a loose state. In the relaxed state, the movable frame 16 will also drive the gear 19 to move. Since the gear 19 is meshed with the rack plate 18, the gear 19 rotates under the action of the rack plate 18, thereby driving the belt 20 to move. Under the action of the belt 20, the rotating rod 21 is driven to rotate, thereby rolling up the No. 1 rolling curtain 17 on the rotating rod 21, and ensuring that the No. 1 rolling curtain 17 always remains in a straight state. The transmission rod 12 will also drive the No. 1 bevel gear 22 to rotate, so that the No. 2 bevel gear 23 rotates, and the No. 2 bevel gear 23 also drives the bidirectional screw rod 24 to rotate, thereby driving the two threaded sleeves 25 to move in a direction close to each other. When the rotating plate 27 is moved, the threaded sleeve 25 will also drive the hinged rod 26 to move, and drive the rotating plate 27 to rotate, and move in the direction of approaching each other. Since the rotating plate 27 has a guiding function, it is ensured that the threaded sleeve 25 will not rotate with the two-way screw rod 24 when moving, and moves along the length direction of the two-way screw rod 24. When the rotating plate 27 rotates, the No. 2 roll-up curtain 30 is no longer tightened. At this time, the No. 2 motor 28 works, driving the winding roller 29 to rotate, thereby winding the No. 2 roll-up curtain 30 on the winding roller 29, so that the No. 2 roll-up curtain 30 is always in a stretched state, thereby realizing the synchronous winding of the two roll-up curtains.
