The roller 1 is wound with sun-shading cloth 2, and the sun-shading cloth 2 is synthesized by terylene, acrylic fibers, chemical fibers and other materials and is used for shading sunlight and sunshine.

The spool 1 is provided with motors (not shown) on both sides, which drive the spool 1 to rotate. In the embodiment, the output shaft of the motor is fixedly connected with the scroll 1, and the scroll 1 is driven to rotate by the motor, so that the winding of the sun-shading cloth 2 is realized.

A sliding shaft 21 is installed on one end of the sun-shading cloth 2 located outside the scroll 1, and the sliding shaft 21 is an iron pipe with a certain weight. The sliding rails 3 are arranged on two sides of the ridge, two ends of the sliding shaft 21 are slidably mounted in the sliding rails 3, when the motor drives the scroll 1 to rotate, and the sun-shading cloth 2 is unreeled, the sun-shading cloth 2 slides from the ridge to the eave under the gravity drive of the sliding shaft 21, so that the roof is covered, and a good sun-shading and sun-screening effect is achieved. The motor signal is connected with a passive indoor temperature sensor (not shown in the figure), the indoor temperature is sensed by the temperature sensor, and when the indoor temperature is higher than the preset temperature, the motor is started, so that sunshade and sun-screening of the roof are realized.

In order to make the sliding shaft 21 slide downwards more stably and reliably, the rollers 211 are rotatably arranged at the two ends of the sliding shaft 21, the rollers 211 are arranged in the sliding rail 3 in a rolling way, and the rollers 211 roll downwards along the sliding rail 3.

Embodiment two:

as shown in fig. 2 and 5, the present embodiment is basically identical to the first embodiment, except that the spool 1 is fixedly provided with a driving wheel 31, the bottom end of the sliding rail 3 is rotatably provided with a driven wheel 32, and a chain 33 or a conveyor belt is provided between the driving wheel 31 and the driven wheel 32, and in this embodiment, the chain 33 is adopted. The sliding shaft 21 is fixed on the chain 33, and the fixing mode can be a connecting rod or a flexible belt, and two ends of the connecting rod or the flexible belt are respectively fixed on the sliding shaft 21 and the chain 33, so that the sliding shaft 21 can move along with the chain 33.
