DETAILED DESCRIPTION

[0015] 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.

[0016] See also Figure 1-3 The utility model provides a technical solution: an agricultural greenhouse with automatic temperature control, including a greenhouse body, wherein the greenhouse body includes a plurality of arc-shaped support rods 1, such as Figure 1 As shown, the support rods 1 are fixedly connected by connecting rods 2, and the outside is covered with greenhouse film. A temperature sensor and a temperature regulating device are arranged inside the greenhouse body for real-time monitoring and real-time regulation of the temperature inside the greenhouse. A ventilation mechanism is arranged on the top of the greenhouse body for quickly discharging the hot air in the greenhouse. The ventilation mechanism comprises a main frame 3, and a film 4 is arranged inside the main frame 3. Under normal circumstances, the film 4 is located inside the main frame 3 to block the main frame 3. By controlling the film 4 to open, the hot air in the greenhouse rises and can be discharged through the main frame 3.

[0017] Specifically, the main frame 3 includes two symmetrically arranged short rods 301 , and long rods 302 are fixedly connected at both ends of opposite surfaces of the short rods 301 . The short rods 301 and the long rods 302 are connected end to end to form a frame structure, and the short rods 301 are arc-shaped.

[0018] Specifically, the surfaces opposite to each other of the two short rods 301 are respectively provided with arc grooves 5, and a movable rod 6 is movably arranged between the arc grooves 5, and the movable rod 6 is arranged parallel to the long rod 302, and a strip through groove 7 connected with the arc groove 5 is provided on one side of the long rod 302, and the strip through groove 7 is extended in the same direction along the length direction of the corresponding long rod 302, and connecting plates 8 are fixedly connected at the lower surfaces of both ends of the long rod 302, and a winding roller 9 is rotatably arranged between the connecting plates 8, and the winding roller 9 is extended in the same direction along the length direction of the corresponding long rod 302, and a connecting groove 10 connected with the strip through groove 7 is provided on the lower surface of the long rod 302, and the coating 4 is rolled up on the winding roller 9, and one end of the coating 4 passes through the connecting groove 10 and the strip through groove 7 and is fixedly connected with the movable rod 6, and a motor is arranged on the surface of the connecting plate 8 at one end, and the motor is used to drive the winding roller 9 to rotate to control the opening and closing of the coating 4.

[0019] Specifically, if Figure 3 As shown, a cylindrical cavity 11 is provided inside the other long rod 302, and the cylindrical cavity 11 is extended in the same direction along the length direction of the corresponding long rod 302. A positioning rod 12 is rotatably provided inside the cylindrical cavity 11, and the positioning rod 12 is extended along the length direction of the cylindrical cavity 11. A rotating sleeve 13 is sleeved and rotatably provided on the outer surface of the positioning rod 12. The rotating sleeve 13 can rotate outside the positioning rod 12. An elastic element is provided between the rotating sleeve 13 and the positioning rod 12, and the elastic element can be a torsion spring. Pull wires 14 are respectively connected to the two ends of the rotating sleeve 13, and the pull wires 14 pass through the side walls of the cylindrical cavity 11 and are fixedly connected to the movable rod 6. Under the action of the torsion spring, the rotating sleeve 13 tends to tighten the pull wire 14, and the movable rod 6 tends to move closer to the cylindrical cavity 11. The movable rod 6 tightens the coating 4 so that the coating 4 can cover the inside of the main frame 3.

[0020] Specifically, the surface of the long rod 302 provided with the strip groove 7 on one side away from the coating 4 is fixedly connected with a strip block 15, and a cleaning plate 16 is movably provided on the inner surface of the strip block 15. The cleaning plate 16 is movably arranged inside the strip groove 7. A spring is arranged between the cleaning plate 16 and the strip block 15. Under the action of the spring, the cleaning plate 16 has a tendency to slide toward the strip groove 7. The end of the cleaning plate 16 away from the strip block 15 is provided with an arc-shaped cleaning brush 17 that fits the surface of the coating 4. Figure 3 As shown, a groove can be set between the strip-shaped through groove 7 and the connecting groove 10, and a roller can be rotatably set in the groove, so that the film 4 fits with the roller, and the friction force of the film 4 when moving is reduced under the action of the roller, thereby increasing the durability of the equipment, and when the film 4 moves, the arc-shaped cleaning brush 17 is in close contact with the surface of the film 4 to clean the surface of the film 4, thereby preventing dust from adhering to the surface of the film 4 and causing the winding roller to affect the light.

[0021] When the utility model is used, the temperature sensor is used to monitor the temperature in the greenhouse. The temperature in the greenhouse is adjusted by the temperature regulating device. The motor drives the winding roller 9 to rotate, tightens the film 4, and the film 4 drives the movable rod 6 to move between the two arc-shaped grooves 5, opening the main frame 3, so that the hot air in the greenhouse can be quickly discharged, achieving rapid cooling.
