Description

Technical Field

[0001] The present invention belongs to the field of ceiling curtains, and in particular relates to a ceiling curtain system suitable for a cone-top building and a use method thereof. Background Art

[0002] Many buildings, especially commercial centers, now have glass roofs. This allows light to penetrate deep into the building, increasing daylight and reducing lighting energy consumption. However, to prevent direct sunlight from creating a distinct light-dark divide within the building, and to prevent the heat and glare caused by direct sunlight in the summer, ceiling curtain systems are installed on the glass roofs. On cloudy days, the curtains open to allow more light in. On sunny days, they close to reduce sunlight, allowing only a portion of the light in. This increases daylight in the building while protecting customers from heat and glare.

[0041] The rope reel 7 includes a lower reel 26 fixed to the output end of the motor 6, a lower rope groove 21 is provided on the outer circumferential surface of the lower reel 26, an upper reel 27 is provided at the upper end of the lower reel 26 for rotational connection, an upper rope groove 20 is provided on the outer circumferential surface of the upper reel 27, a spring 28 is provided between the upper reel 27 and the lower reel 26, the upper end of the spring 28 is connected to the upper reel 27, and the lower end of the spring 28 is connected to the lower reel 26.

[0042] A limit plate 29 connected to the lower winder 26 is provided above the upper winder 27 , and the motor 6 has a clamping mechanism, which is widely available on the market.

[0043] Working principle: Figure 7 As shown, since the two ends of the steel cable 8 are respectively located on both sides of the rope reel 7, when the rope reel 7 rotates, one end of the steel cable 8 is loosened on the rope reel 7, and the other end of the steel cable is wound on the rope reel 7. When the rope reel 7 reverses its rotation direction, one end of the steel cable 8 is wound on the rope reel 7, and the other end of the steel cable 8 is loosened on the rope reel 7.

[0044] When the sun is strong, the motor 6 rotates forward, driving the rope reel 7 to rotate forward (first driving the lower reel 26 to rotate forward, and the lower reel 26 drives the upper reel 27 to rotate synchronously through the spring 28). The lower reel 26 winds the steel cable 8, which drives the buckle 11 to move inward, driving the inner end of the fabric 5 to move inward, and the steel cable 8 wound on the upper reel 27 is disengaged. At the same time, the friction between the steel cable 8 and the outer roller 16 drives the outer roller 16 to rotate, and the outer roller 16 drives the inner roller 14 to rotate through the ball 18. The inner roller 14 drives the rotating tube 4 to rotate through the torsion spring 31, so that the fabric 5 can be smoothly disengaged from the rotating tube 4. When the inner end of the fabric 5 is pulled near the mounting plate 2, the ceiling curtain system is closed, achieving the sunshade function.

[0045] On rainy days, the motor 6 reverses, driving the rope reel 7 to rotate in the opposite direction. The steel cable 8 is wound on the upper reel 27, which drives the buckle 11 to move outward, driving the inner end of the fabric 5 to move outward. The steel cable 8 wound on the upper reel 27 is disengaged. At the same time, the friction between the steel cable 8 and the outer roller 16 drives the outer roller 16 to rotate. The outer roller 16 drives the inner roller 14 to rotate through the ball 18. The inner roller 14 drives the rotating tube 4 to rotate through the torsion spring 31, causing the fabric 5 to be wound around the rotating tube 4. When the inner end of the fabric 5 approaches the rotating tube 4, the ceiling curtain system opens, increasing light transmission.

[0046] The method for using the ceiling curtain system is to change the number of winding layers of the fabric 5 on the rotating tube 4 through the motor 6, change the shading area of ​​the fabric 5, and change the light transmission amount of the ceiling curtain system.

[0047] The design points of the present invention include the following:

[0048] 1) Through multiple trapezoidal fabrics, when multiple fabrics are detached from the rotating tube at the same time, the component becomes a nearly conical covering, blocking the cone top of the building and achieving shading. When multiple fabrics are wound onto the rotating tube at the same time, the cone top of the building is exposed, achieving light transmission.

[0049] 2) A single motor drives all fabric winding actions simultaneously, reducing costs.

[0050] 3) The pre-tightening force of the spring 28 is used to keep the steel cable 8 in a taut state at all times, and the steel cable 8 will not relax, ensuring that there is sufficient friction between the steel cable 8 and the outer roller sleeve 16. The steel cable 8 can drive the rotating tube 4 to rotate during the movement, thereby realizing the winding and disengagement of the fabric on the rotating tube 4.

[0051] 4) By optimizing the structures of the inner roller sleeve 14 and the outer roller sleeve 16 and arranging the ball 18 between the inner roller sleeve 14 and the outer roller sleeve 16, the steel cable 8 between the outer roller sleeve 16 and the winder 27 is made parallel to the rotation plane of the outer roller sleeve 16. While ensuring that the outer roller sleeve 16 can drive the rotating tube 4 to rotate through the inner roller sleeve 14, it ensures that the steel cable 8 will not escape from the spiral groove 19, thereby reducing the failure rate.

[0052] 5) During the process of pulling out and reeling in the fabric 5, the outer diameter of the fabric 5 remaining on the rotating tube 4 changes, causing the distance that the inner end of the fabric 5 pulled out by the steel cable 8 passes to be difficult to be equal to the length of the fabric 5 being reeled in or unwound on the rotating tube 4. During the movement of the steel cable 8, the unfolded portion of the fabric 5 may become loose or overly tight. When the fabric is loose, its appearance decreases. When the fabric is overly tight, the motor load increases and damages the fabric. The present invention provides a torsion spring 31 between the inner roller 14 and the rotating tube 4, so that a speed difference can be formed between the rotating tube 4 and the outer roller 16, thereby ensuring that the fabric can remain moderately tight when pulled out to any length. The tension is relatively balanced, does not increase the energy consumption of the motor 6, is more energy-efficient, and also improves the aesthetics of the ceiling curtain system.

[0053] 6) The connection structure between the steel cable 8 and the fabric 5 is optimized. On the basis of easy assembly, the stress-bearing area of ​​the fabric 5 is increased, the inner end of the fabric 5 is prevented from being torn, the service life of the fabric 5 is increased, and the cost of equipment use is reduced.
