[0020] Step 3: Actively dissipate heat inside the greenhouse body through active heat dissipation components. High-temperature air is discharged vertically upward along the longitudinal heat dissipation channel between the greenhouse body and the placement trough.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. Active heat dissipation components are used to actively dissipate heat inside the greenhouse body. High-temperature air is discharged vertically upward along the longitudinal heat dissipation channel between the greenhouse body and the placement trough. At the same time, the high-temperature air inside the greenhouse body is discharged, while the transverse heat dissipation channel between the ridge-shaped skylight and the heat dissipation trough is used to draw air inward. The exhaust and intake channels are blocked by the air guide shell. External air enters the air guide shell and enters the lower part of the greenhouse body through the air guide component. This converts the airflow at the top into a bottom-up gas flow exchange inside the greenhouse body, improving the heat dissipation efficiency inside the greenhouse body.

[0023] 2. The ridge peak sunroof drives two movable plates to rise synchronously, the movable plates drive corresponding connecting rods and round pins to rise synchronously, the round pins are limited and guided by the inclined guide grooves during the moving process, so that the movable plates rotate along the hinge during the rising process, thereby turning down and opening the placing groove.

[0024] 3. When the wind speed detected by the wind speed sensor exceeds the safety value, the controller connected to the wind speed sensor controls the transmission shaft of the first electric cylinder to return to the initial position, thereby driving the ridge peak sunroof to descend and close the air flow channel. When strong wind acts on the top of the greenhouse main body and the surface of the ridge peak sunroof, the huge wind pressure generated is easy to damage the greenhouse main body. When the ridge peak sunroof descends, the movable plates reseal the placing groove. When the strong wind acts on the surface of the movable plates, the elastic pressure relief assembly can drive the guide bracket to elastically displace, so that the movable plates open slightly downward under the wind pressure, allowing part of the strong wind to pass through, thereby greatly reducing the wind load acting on the top of the greenhouse main body and reducing the damage of strong wind to the greenhouse main body.

6. The intelligent greenhouse automatic lifting top window device according to claim 5, characterized in that, The temperature sensor is fixedly mounted on the support frame and located below the exhaust housing.

7. The intelligent greenhouse automatic lifting top window device according to claim 2, characterized in that, A wind speed sensor is fixedly installed on the top of the ridge-shaped skylight, and an elastic pressure relief component is installed on the guide bracket.

8. The intelligent greenhouse automatic lifting top window device according to claim 7, characterized in that, The elastic pressure relief assembly includes four U-shaped slide rails, all of which are fixedly connected to the top of the connecting frame. Four guide brackets are slidably connected inside the corresponding U-shaped slide rails. A circular rod is fixedly connected inside the U-shaped slide rail, and the circular rod is slidably inserted into the corresponding guide bracket. A second spring is sleeved on the circular rod, and the second spring is fixedly connected between the corresponding guide bracket and the U-shaped slide rail.

9. The intelligent greenhouse automatic lifting top window device according to claim 8, characterized in that, A second electric cylinder is fixedly installed at both ends of the top of the connecting frame. Limiting rings are fixedly connected to the top of the four guide brackets. A positioning pin is fixedly connected to the drive shaft of the second electric cylinder, and one end of the positioning pin is inserted into the two adjacent limiting rings.

10. A method for opening a window in an automatic lifting roof-opening window device for a greenhouse, applicable to the intelligent automatic lifting roof-opening window device for a greenhouse as described in any one of claims 1-9, characterized in that, The method includes the following steps: Step 1: Monitor the temperature inside the greenhouse body in real time using a temperature sensor. When the temperature inside the greenhouse body exceeds the set value, the controller connected to the temperature sensor controls the first electric cylinder to work. The drive shaft of the first electric cylinder drives the ridge-shaped skylight to move upward. Step 2: When the ridge-type sunroof rises, the rotating component drives the movable plate to rotate downwards along the hinge. When the ridge-type sunroof moves to the highest point, the movable plate is in a vertical state, so that the two placement slots are in the maximum unfolded state. Step 3: Actively dissipate heat inside the greenhouse body through active heat dissipation components. High-temperature air is discharged vertically upward along the longitudinal heat dissipation channel between the greenhouse body and the placement trough. At the same time, the high-temperature air inside the greenhouse body is discharged, while the transverse heat dissipation channel between the ridge-shaped skylight and the heat dissipation trough is drawn inward. The exhaust channel and the intake channel are blocked by the air guide shell. External air enters the air guide shell and enters the lower part of the greenhouse body through the air guide component.
