[0002] Agricultural greenhouses, also known as greenhouses, are facilities that can transmit light, keep warm (or heat), and are used to grow plants. In seasons that are not suitable for plant growth, they can provide a greenhouse growth period and increase production. They are mostly used for the cultivation or seedling raising of warm-loving vegetables, flowers, trees, and other plants in low-temperature seasons. There are many types of greenhouses, which can be divided into many categories according to different roof frame materials, lighting materials, shapes, and heating conditions.
[0003] At present, the existing temperature control ventilation devices for agricultural greenhouses generally ventilate the inside of the greenhouse through ventilation fans or fans. Since the fan is installed on the outside of the greenhouse, a large amount of dust will accumulate on the exposed surface of the fan blades and inside the chassis, resulting in reduced ventilation efficiency. In addition, the fan is generally fastened to the outside of the greenhouse by bolts. When maintaining the fan, tools are required to remove the bolts, which is inconvenient to operate. Utility Model Content

[0012] In summary, the utility model mainly has the following beneficial effects:
[0013] 1. The existing temperature control ventilation device for agricultural greenhouses generally fastens the fan to the greenhouse by bolts. When the fan is maintained and repaired, the bolts need to be removed one by one, which is a complicated step. The utility model provides a chassis, a fan, a slide groove and a filter. When the fan is started, air passes through the fan and enters the interior of the greenhouse. The dust and impurities in the air are blocked by the filter. The guide rods above and below the chassis are pulled, and the guide rods drive the limit rods to move, so that the limit grooves at the connecting blocks lose the engagement connection with the limit rods, and then the chassis and the greenhouse are disassembled, thereby achieving the purpose of facilitating the disassembly and maintenance of the fan inside the chassis;
[0014] 2. Existing temperature-controlled ventilation devices for agricultural greenhouses generally collect light energy through solar photovoltaic panels and power the ventilation devices. The angles and directions of the solar panels are mostly fixed and cannot be adjusted according to the light. The utility model sets a fixed block, a large gear, a motor, a rotating shaft, a small gear, a sliding groove, a sliding block and an electric push rod. The electric push rod is started, and the electric push rod pushes the sliding block to move inside the sliding groove. While the sliding block drives the support rod to move, the photovoltaic panel moves up and down with the hinge seat as the axis, so that the inclination angle of the photovoltaic panel can be adjusted. After that, the motor is started, and the output end of the motor drives the rotating shaft and the small gear to rotate, and the small gear drives the large gear and the fixed shaft to rotate accordingly, and the fixed shaft drives the connecting plate to rotate, thereby achieving the purpose of facilitating the adjustment of the direction of the photovoltaic panel.
