In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in fig. 1, a solar greenhouse curtain system includes several curtains 10 installed outside the solar greenhouse. Two opposite sides of each curtain 10 are slidably mounted on a slide rail 30 through pulley blocks 20. Specifically, the curtain 10 is a sunshade net or a heat preservation quilt, and is specifically selected according to the environmental temperature in practical application. The slide rails 30 are arranged on the outer surface of the sunlight greenhouse and extend from the bottom of the rear wall to the lower part of the front roof. The number of the pulley blocks 20 is multiple, two opposite side edges of the curtain 10 are fixedly arranged on the pulley blocks 20, and the pulley blocks 20 are slidably arranged in the slide rails 30. At opposite ends of the curtain 10 are mounted automatic traction devices 40, respectively, one of the automatic traction devices 40 being mounted at the bottom end of the front roof and the other automatic traction device 40 being mounted at the bottom end of the rear wall. In use, when one of the automatic traction devices 40 pulls one end of the curtain 10, the other automatic traction device 40 is in a relaxed state, and the two devices cooperate with each other to slide the curtain 10 as a whole along the slide rails 30 toward the rear wall or the front roof. Note that during the sliding process, the entire curtain 10 is in an extended state and does not roll over or fold.

In the solar greenhouse curtain system in the embodiment of the invention, two opposite side edges of the curtain 10 are slidably installed in the slide rails 30 through the pulley blocks 20, two automatic traction devices 40 arranged at two ends of the curtain 10 are matched with each other, and the pulley blocks 20 move to one side along the slide rails 30 after relaxation. The whole process adopts an automatic moving mode, manual participation is not needed, the problem that the reel accidentally injures people is avoided, and potential safety hazards are reduced. In addition, the two sides of the curtain 10 are installed in the slide rails 30, and the slide rails 30 help the greenhouse framework to share the pressure of the curtain 10, so that the overall durability of the greenhouse is improved. In addition, the two automatic traction devices 40 cooperate with each other to tension the curtain 10 along the outer surface of the greenhouse, thereby resisting the influence of long-term operation or bad weather on the flatness of the curtain 10.

Specifically, the automatic traction device 40 in the embodiment of the present invention includes a traction rod 41, a traction wire 42, a rotating shaft 43, and a driving unit 44. Wherein, the traction rod 41 is fixedly installed at one end of the curtain 10, one end of the traction steel wire 42 is fixedly installed on the traction rod 41, and the other end is fixedly installed on the rotating shaft 43. The driving unit 44 is used for driving the rotating shaft 43 to rotate, so as to drive the curtain 10 to move towards the rotating shaft 43. It should be noted that, in the solar greenhouse curtain system of the embodiment of the present invention, the plurality of curtains 10 may share the rotating shaft 43 and the driving unit 44, or one rotating shaft 43 and one driving unit 44 may be separately provided for each curtain 10. When the common mode is adopted, the plurality of curtains 10 rise and fall simultaneously; when the individual arrangement is adopted, the lifting of each curtain 10 can be controlled separately as required.

In order to ensure the smoothness of the drive, the drive unit 44 includes a traction motor and a reduction motor connected to the traction motor. The output end of the reduction motor is connected to the rotation shaft 43, so that the power of the traction motor is smoothly transmitted to the rotation shaft 43.

In order to ensure the stability of the running direction of the traction steel wires 42 during the use process, the automatic traction device 40 also comprises a steel wire track 45 installed on the greenhouse roof. Specifically, as shown in fig. 2, a clamping groove 451 is arranged below the steel wire track 45 and used for fixedly mounting the greenhouse film; a steel wire hole 452 is provided above for the traction steel wire 42 to pass through. The wire holes 452 are configured to guide the direction of movement of the pull wire 42 to prevent deflection.

Specifically, the length of the sunlight greenhouse is 60m, the span is 8m, the height of the rear wall is 5m, and the distance between two slide rails 30 arranged on the same curtain 10 is 4 m. As shown in fig. 3, there is a gap between two slide rails 30 between two adjacent curtains 10, and for this purpose, a framework 50 is specially provided to connect the two slide rails 30. For convenience of description, the two slide rails 30 located at two sides of the same curtain 10 are named as a first slide rail 31 and a second slide rail 32. The first slide rail 31 installed on one curtain 10 is connected to the second slide rail 32 installed on the other curtain 10 adjacent to the curtain 10 by the framework 50.

As shown in fig. 3, the frame 50 is made of steel. The frame 50 is provided with a closed chamber 51 having one side opened and an open chamber 52 adjacent to the closed chamber 51. The curtain 10 extends out of the opening, and the outer wall of the open chamber 52 is C-shaped. The first slide rail 31 is accommodated in the closed chamber 51 and can move laterally along the closed chamber 51 (with the longitudinal direction of the sunlight greenhouse being the lateral direction). The second slide rail 32 is mounted outside the open chamber 52, i.e. the open chamber 52 is located between the second slide rail 32 and the closed chamber 51. Therefore, the first sliding rail 31 and the second sliding rail 32 on two adjacent curtains 10 are shielded by the framework 50, and the sun shading or heat preservation effect is optimized. A spring damper 60 is installed in the open chamber 52, and one end of the spring damper 60 is connected to the first slide rail 31 to buffer and tension the curtain 10.

Specifically, the spring damper 60 includes a rod 61 disposed transversely and a spring 62 sleeved on the rod 61. One end of the rod 61 is located in the closed chamber 51 and connected to the first slide rail 31 in the closed chamber 51, and the other end is located in the open chamber 52. The outer wall of the first slide rail 31 is provided with a slide groove, and the end part of the rod body 61 is clamped in the slide groove and can slide along the slide groove. The spring 62 is located entirely within the open chamber 52. When the pulley block 20 slides in the first sliding rail 31, vibration is easily generated, which causes the first sliding rail 31 to move transversely in the closed chamber 51. The spring damper 60 can be used for damping and limiting the position of the first slide rail 31, so as to prevent wrinkles from being generated during the movement of the curtain 10.

The sliding rail 30 in the embodiment of the invention is a square steel pipe with an opening at one side, and the pulley block 20 is slidably installed in the sliding rail 30. In order to keep the curtain 10 laterally taut, the pulley block 20 comprises two horizontal wheels 21 arranged parallel to the curtain 10 and one vertical wheel 22 arranged perpendicular to the curtain 10. The two horizontal wheels 21 are connected with one vertical wheel 22 through a T-shaped connecting rod, and the curtain 10 is fixedly arranged between the two horizontal wheels 21.

In order to make the sun-proof and heat-preserving effects more excellent, heat-insulating clips 70 are installed at the connection portions of the slide rails 30 and both sides of the curtain 10.

In addition, a first stop device 33 and a second stop device 34 are provided on the slide rail 30. The first limiting device 33 is used for limiting the limit position of the curtain 10 moving towards the front roof; the second position limiting device 34 is used to limit the limit position of the curtain 10 moving towards the rear wall. Specifically, if the automatic traction device 40 installed on the front roof pulls the curtain 10 to move towards the front roof, when one end of the curtain 10 far away from the front roof moves to the first limiting device 33, the automatic traction device 40 stops pulling, the curtain 10 covers the front roof and moves in place, and therefore the sun shading or heat preservation is achieved. If the automatic traction device 40 installed at the rear wall pulls the curtain 10 to move towards the rear wall, when one end of the curtain 10 far away from the front roof moves to the second limiting device 34, the automatic traction device 40 at the rear wall stops pulling, the curtain 10 moves to the rear wall, and the front roof is in a state of no sun shading and no heat preservation. The method can be specifically operated according to seasons and day and night temperature states, and is flexible and convenient.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
