[0003] There are two types of existing heat preservation rolling and unrolling driving devices in greenhouses in China, namely, one-way pull rope type and shaft rolling type. The one-way pull rope is only pulled by the rope when rolling up, and rolls down by gravity when lowering. It is required that the ratio of the greenhouse height to the vertical projection of the lighting surface is greater than 0.56, otherwise it cannot be lowered normally; the torque required for the shaft rolling type is more than 4 times that of the pull rope type, and the adjacent part of the motor reducer often deforms and sags, and other parts also need to be adjusted frequently, otherwise the rolling and unrolling will be uneven. Neither of the above two is suitable for use as an automatic control execution device, so a coaxial pull rope type heat preservation driving device in a greenhouse is proposed to solve the above-mentioned problems.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the scope of protection of the present utility model.

[0020] Please refer to Figures 1-4 , a coaxial rope-pulling type heat preservation driving device in this embodiment, including a solar greenhouse body 1. The solar greenhouse body 1 includes columns 101, an inner arch 102, and an outer arch 103 located inside the solar greenhouse body 1. A heat preservation quilt 2 is laid on the top of the inner arch 102, and a winding assembly 3 is installed inside the solar greenhouse body 1.

[0021] It should be noted that the heat preservation quilt 2 has characteristics such as heat preservation, light transmittance, moisture resistance, easy retraction and extension, and long service life. The heat preservation quilt 2 is often used for heat preservation indoors. Through the cooperation among the above-mentioned outer arch 103, inner arch 102, columns 101, winding assembly 3, etc., a driving device for use in a coaxial rope-pulling type greenhouse can be formed. This device uses two-way pulling and can use an internationally standard and commonly used curtain pulling motor with a smaller torque, saving energy and reducing consumption. It does not require a height projection ratio greater than 0.56. And through the control switch arranged inside the inner arch 102, it runs very reliably. This utility model can be used as an execution device for greenhouse automatic control.

[0022] The winding assembly 3 includes a driving motor 301 installed on the top of the inner arch 102. A winding shaft 302 is fixedly installed at the output shaft of the driving motor 301. A winding wheel 303 is fixedly installed on the outer surface of the winding shaft 302. A first pulling rope 305 is wound around the outer surface of the winding wheel 303. Four guiding wheels 304 are fixedly installed on the inner top wall of the outer arch 103. A tension spring 306 is fixedly installed on the inner top wall of the outer arch 103. A tension wheel 307 is fixedly installed at the bottom of the tension spring 306. A second pulling rope 308 is connected to the outer surface of the winding shaft 302. One end of the first pulling rope 305 away from the winding wheel 303 is connected to the heat preservation quilt 2, and one end of the second pulling rope 308 away from the winding shaft 302 is wound around the heat preservation quilt 2.

[0023] Specifically, when winding the heat preservation quilt 2, the driving motor 301 is started to drive the winding shaft 302 to rotate. The winding shaft 302 drives a plurality of winding wheels 303 to rotate. The heat preservation quilt 2 is wound through the first pulling rope 305. Since the running directions of the first pulling rope 305 and the second pulling rope 308 are different, during the winding process of the first pulling rope 305, the second pulling rope 308 is in a state of being retracted and extended, so as to achieve the winding of the heat preservation quilt 2.

[0024] The first drawstring 305 is slidably connected to the outer surfaces of the four guide wheels 304.

[0025] Specifically, by arranging the guide wheels 304, the direction of the first drawstring 305 is guided, the friction is reduced to save effort, and the tension is maintained.

[0026] The number of the winding wheels 303 is set to be not less than twenty-two, and the twenty-two winding wheels 303 are equidistantly distributed on the outer surface of the reel 302. The outer surfaces of the twenty-two winding wheels 303 are all wound with the first drawstring 305, and one ends of the twenty-two first drawstrings 305 are all connected to the heat preservation quilt 2.

[0027] Specifically, arranging multiple winding wheels 303 can evenly distribute the pulling force for the winding of the heat preservation quilt 2 and maintain stable operation, making the heat preservation quilt 2 move more smoothly, reducing the inertial influence caused by sudden pulling or stopping, and improving the stability and reliability of the entire system.

[0028] The number of the second drawstrings 308 is seven, and one end of each second drawstring 308 is located between one ends of every three first drawstrings 305. The twenty-two first drawstrings 305 and the seven second drawstrings 308 are arranged at intervals.

[0029] Specifically, the arrangement at intervals can ensure that the heat preservation quilt 2 is evenly stressed during the winding and unwinding processes, preventing damage or deformation caused by uneven stress.

[0030] The running directions of the twenty-two first drawstrings 305 and the seven second drawstrings 308 are set to be opposite. One ends of the seven second drawstrings 308 are tied to the upright post 101.

[0031] Specifically, during the winding process of the first drawstring 305, the second drawstring 308 is in the state of winding and unwinding, and the running directions of the two drawstrings are opposite.

[0032] In summary, for this coaxial drawstring type heat preservation driving device in the greenhouse, through the cooperation among the upright post 101, the inner arch 102, the outer arch 103, the heat preservation quilt 2 and the winding assembly 3, when winding the heat preservation quilt 2, the driving motor 301 is started to drive the reel 302 to rotate, the reel 302 drives multiple winding wheels 303 to rotate, and the heat preservation quilt 2 is wound through the first drawstring 305. Since the running directions of the first drawstring 305 and the second drawstring 308 are different, during the winding process of the first drawstring 305, the second drawstring 308 is in the state of winding and unwinding, so as to achieve the winding of the heat preservation quilt 2, and the tension pulley 307 can control the tension of the first drawstring 305 to ensure that the heat preservation quilt 2 maintains an appropriate tension state during the winding or unfolding process, preventing slack or excessive tightness.
