[0042] See also Figure 6 , Figure 7 and Figure 8 Specifically, when the first traction device 3 and the second traction device 6 are working, their working principles are as follows:

[0043] When the side of the awning does not need to be protected from wind and rain, the first rainproof cloth 2 is in a tightened state, and the iron ring of the first rainproof cloth 2 is connected to the hook 8 of the first guide rail 1, and the hooks 8 on the first guide rail 1 are close to each other. The second rainproof cloth 5 is similar. When the side of the awning does not need to be protected from wind and rain, the second rainproof cloth 5 is in a tightened state, and the iron ring of the second rainproof cloth 5 is connected to the hook 8 of the second guide rail 4, and the hooks 8 on the second guide rail 4 are close to each other. After the first rainproof cloth 2 is tightened, it is located on the left side of the awning, and the hooks 8 on the first guide rail 1 are concentrated on the left side of the first guide rail 1. After the second rainproof cloth 5 is tightened, it is located on the right side of the awning, and the hooks 8 on the second guide rail 4 are concentrated on the right side of the second guide rail 4.

[0044] When the side of the awning needs to be protected from wind and rain, the first traction rope 33 is connected to the left hook 8 of the first guide rail 1 on the side of the awning, and then the first traction machine 31 rotates counterclockwise. Under the action of the first guide wheel 32, the first traction rope 33 pulls the left hook 8 on the first guide rail 1. The hook 8 can move horizontally under the action of the pulley 7 and the first guide rail 1. When the first traction rope 33 pulls the hook 8 to move to the right, it can drive the first rainproof cloth 2 on the hook 8 to unfold to the right, thereby covering the empty side of the awning. When the first rainproof cloth 2 is fully unfolded, the left hook 8 on the first guide rail 1 is pulled to the rightmost side of the first guide rail 1. While the first traction rope 33 is playing a traction role, the second traction rope 63 is also performing a traction operation. The second traction rope 63 is connected to the right hook 8 of the second guide rail 4 on the side of the awning. Then the second traction machine 61 rotates clockwise, and the right hook 8 on the second guide rail 4 is pulled by the second traction rope 63, driving the second rainproof cloth 5 on the hook 8 to unfold to the left to cover the empty side of the awning. When the second rainproof cloth 5 is fully unfolded, the right hook 8 on the second guide rail 4 is pulled to the leftmost side of the second guide rail 4. Finally, the following is obtained: Figure 8 In the state shown, the first rainproof cloth 2 and the second rainproof cloth 5 are both unfolded to cover the side of the awning, thereby achieving the effect of protecting the side of the awning from wind and rain.

[0045] When the side of the shelter is not required to be windproof and rainproof, the unfolded first rainproof cloth 2 and second rainproof cloth 5 need to be tightened. At this time, the first traction rope 33 is connected to the left hook 8 of the second guide rail 4, and then the first traction machine 31 rotates counterclockwise, and the left hook 8 on the second guide rail 4 is pulled to the right by the first traction rope 33, so that the second rainproof cloth 5 is tightened to the right, and finally the tightening is concentrated on the right side of the shelter. At the same time, the second traction rope 63 is connected to the right hook 8 of the first guide rail 1, and then the second traction machine 61 rotates clockwise, and the right hook 8 on the first guide rail 1 is pulled to the left by the second traction rope 63, so that the first rainproof cloth 2 is tightened to the left, and finally the tightening is concentrated on the left side of the shelter.

[0046] Specifically, the two traction machines are winches, the traction force of the two traction ropes is not less than 5KN, and the traction device is provided with a unified logic control system.

[0047] See also Figure 7 and Figure 8 Furthermore, the upper ends of the first rainproof cloth 2 and the second rainproof cloth 5 are fan-shaped, and the lower ends of the first rainproof cloth 2 and the second rainproof cloth 5 are square.

[0048] See also Figure 8Specifically, considering that the awning will pass through the single piles 12 of different diameters for circumferential welding, the two ends of the awning are designed in the form of flexible curtains, that is, rainproof cloth is used. The rainproof cloth is cut into a fan-shaped style, such as Figure 8 The style shown can ensure that when the tarpaulin is pulled to the other side, enough tarpaulin falls on the single pile 12.

[0049] See also Fig. 9 Furthermore, the rain curtain device of the wind and rain shed also includes a pile bottom windproof mechanism 11, and the pile bottom windproof mechanism 11 includes a third rainproof cloth 111, a steel wire rope 112 and a side hanging ear, the side hanging ear is symmetrically connected to the two main legs of the beam side of the wind and rain shed, the steel wire rope 112 is connected to the side hanging ear, and the third rainproof cloth 111 is connected to the steel wire rope 112.

[0050] In a specific implementation plan, a side lifting lug is set every 500mm within a 2000mm height range of the main leg on the side of the canopy beam. The side lifting lug is used for pulling the wire rope. The bottom of the single pile can be windproofed by using a turnbuckle bolt or a small hand winch to tighten the wire rope according to the wind force, and the rainproof cloth at the bottom of the single pile is tied to the wire rope.

[0051] To sum up, the utility model provides a rain curtain device for a canopy, which forms a rain curtain at the side port of the canopy through three rainproof cloths, which can effectively reduce the wind-receiving area at both ends of the canopy, thereby reducing the wind speed through the canopy, and to a certain extent prevent the rain from drifting into the canopy with the help of wind when it is too heavy, and can reduce the impact of windy and rainy weather on the single pile segmented welding operation in the canopy.
