The traction rope 108 passes through a pulley 109 on a greenhouse truss fixed at the top of the greenhouse column and is connected to a heat preservation rolling curtain connecting rod 110.

[0038] The upward pulling system 1 generates power through the first motor 101, drives the first transmission shaft 105 to rotate through the first speed reducer 104, and pulls the heat preservation rolling curtain 209 through the traction rope 108, so that it slides orderly through the sliding track 3.

[0039] See Figure 3 , the structure of the specific embodiment of the winding and retracting system 2 of the present utility model includes a second motor 201, on which a second pulley 202 is installed, and is connected to a second speed reducer 204 equipped with a pulley through a second V-belt 203.

[0041] See Figure 4 , the sliding track 3 of the present utility model is a clever utilization of the greenhouse skeleton structure, and specifically includes a greenhouse track skeleton 301 with an opening 306 arranged on the upper side.

[0042] See Figure 5,6, The structure of the specific embodiment of the adjustable spring support device 4 of the present utility model includes a roller fixing frame 401, in which several second rollers 402 are installed. The heat preservation rolling curtain 209 is arranged on the second rollers 402. The lower part of the roller fixing frame 401 is provided with threads and is equipped with an adjusting nut 403.

[0043] The adjustable spring support device 4 mainly enables the support frame 404 to always have a certain supporting ability for the rolled-up heat preservation rolling curtain 209 through the adjustable spring 406, thereby reducing the pressure on the second transmission shaft 205 from the side and preventing uneven force caused by deformation.

[0044] See Figure 7 , The structure of the specific embodiment of the greenhouse framework 5 of the present utility model is composed of an outer framework 501 and an inner framework 502. The outer framework 501 is a single-layer oval galvanized steel pipe. The inner framework 502 is jointly composed of a reinforced arch frame, a common arch frame and a greenhouse track framework 301.

[0045] Taking the large-span asymmetric double-arch double-film greenhouse for rolling up the inner heat preservation rolling curtain as an example, by supporting two sets of the upper-pulling type rolling curtain systems of the present utility model, the pulling up and rolling up of the heat preservation rolling curtain can be realized. The heat preservation rolling curtain 209 can be a heat preservation quilt or other covers, such as a sunshade net, a curtain, etc.

[0046] The specific working process of the present utility model is as follows:

[0047] Pull-up of the heat-insulating rolling curtain 209: The first motor 101 rotates. Through the transmission of the first triangular belt 103, the first transmission shaft 105 of the first speed reducer 104 rotates counterclockwise, further driving the traction rope 108 to generate a pulling force, dragging the heat-insulating rolling curtain connecting rod 110 to make the heat-insulating rolling curtain 209 rise slowly and orderly. At this time, the wire winding roller 107, the pulley 109 of the first transmission shaft 105 and the greenhouse track skeleton 301 limit the movement track of the traction rope 108. Cooperating with the heat-insulating rolling curtain connecting rod 110, the whole heat-insulating rolling curtain 209 moves upward at the same rate. The first bearing 106, the second bearing 206, the third bearing 303 and the first roller 302 greatly reduce the friction force, making the movement smoother. At this time, the second motor 201 is in a power-off state, and the second transmission shaft 205 rotates clockwise under the traction of the heat-insulating rolling curtain 209 until the heat-insulating rolling curtain 209 reaches the top of the greenhouse, and the first motor 101 stops rotating. During this process, as the diameter of the roll of the heat-insulating rolling curtain 209 decreases, the spring 406 elongates, making the second roller 402 closely adhere to the heat-insulating rolling curtain 209 to provide a supporting force.

[0048] Rolling-up of the heat-insulating rolling curtain 209: The second motor 201 rotates forward, driving the second speed reducer 204 to rotate through the second triangular belt 203, so that the second transmission shaft 205 rotates counterclockwise, winding the heat-insulating rolling curtain 209 around the second transmission shaft 205. As the diameter of the roll of the heat-insulating rolling curtain 209 increases, the spring 406 in the adjustable spring support structure 4 is in a compressed state, and the provided supporting force is getting larger and larger, so as to reduce the pressure on the second transmission shaft 205. At this time, the wire winding roller 107, the pulley 109 of the first transmission shaft 105 and the greenhouse track skeleton 301 limit the movement track of the traction rope 108. Cooperating with the heat-insulating rolling curtain connecting rod 110, the whole heat-insulating rolling curtain 209 moves downward at the same rate. The first bearing 106, the second bearing 206, the third bearing 303 and the first roller 302 greatly reduce the friction force, making the movement smoother. During this process, the first motor 101 is in a power-off state and rotates clockwise under the traction of the traction rope 108, avoiding potential safety hazards caused by the slack of the traction rope 108.
