Since the width of the greenhouse is about 10 meters, the length of the closed loop formed by the hanging steel cable and the driving steel cable is at least twice the length of the greenhouse. In addition, the unfolding and reeling directions of the inner insulation blanket are set along the extension of the greenhouse frame.

The screw rod is rotated to adjust the distance between the first pivot axis and the second pivot axis, so that the rolling element is raised or lowered relative to the third bottom plate, so that the rolling element and the first top plate maintain a moderate tension degree, so that the traveling gear drives the suspension moving component to move along the traveling tooth plate without loosening from the traveling tooth plate.
5. The direct-drive hanging moving device for a greenhouse as claimed in claim 4, characterized in that: The rolling member includes a support frame and two rollers. The first support and the second support are arranged at the lower end of the support frame, and the third support and the fourth support are arranged at the upper end of the support frame. The upper end of the second rotating member is rotatably connected to the first support, and the upper end of the fourth rotating member is rotatably connected to the second support. A roller is respectively arranged on the third support and the fourth support. The two rollers are in rolling contact with the first top plate to maintain the tension degree and relative movement of the shell and the beam frame.
6. The direct-drive hanging moving device for a greenhouse as claimed in claim 4, characterized in that: A limiting wheel is arranged on the fifth side plate, and the wheel surface of the limiting wheel has an inner groove, and the upper end edge of the limiting plate is embedded in the inner groove, so that the limiting wheel is not easy to be separated during the process of rolling along the limiting plate.
7. The direct-drive hanging moving device for a greenhouse as claimed in claim 4, characterized in that: The third side plate is provided with a motor, the motor and the travel gear are respectively located on two sides of the third side plate, and the rotating shaft of the motor is transmission-connected with the travel gear.
8. A greenhouse, characterized in that: The greenhouse comprises a front wall, a rear wall, a greenhouse frame, an inner insulation blanket, and a plurality of direct-drive hanging mobile devices for the greenhouse as described in any one of claims 1 to 7. A plurality of greenhouse frames are set up between the front wall and the rear wall. The beams of each direct-drive hanging mobile device for the greenhouse are arranged in the greenhouse. Each beam is arranged along the length direction of the greenhouse, or each beam is arranged along the width direction of the greenhouse. Two adjacent beams are arranged at intervals. Each beam is located below all greenhouse frames. Each beam is connected to all or part of the greenhouse frames. A plurality of hanging mobile components are connected in sequence to form a first row of hanging mobile components, a second row The extension directions of the hanging moving components, the Nth column of hanging moving components, the first column of hanging moving components, the second column of hanging moving components, and the Nth column of hanging moving components are perpendicular to each other, the first column of hanging moving components, the second column of hanging moving components, and the Nth column of hanging moving components are connected to the inner insulation quilt after being spaced apart from each other, the first column of hanging moving components moves away from or close to the second column of hanging moving components to unfold or fold the inner insulation quilt between the first column of hanging moving components and the second column of hanging moving components, and the folding or unfolding of the inner insulation quilt is achieved by successively moving the N-1th column of hanging moving components and the Nth column of hanging moving components closer to or away from each other.
