[0027] See also Figure 2 , Figure 3 The positioning mechanism 4 includes a positioning roller 41, a direction-changing roller 42 and a tension roller 43. The positioning roller 41 is arranged directly below the winding roller 5. One end of the waterproof cloth is passed around the positioning roller to position it to prevent deviation. First electric push rods 44 are arranged on both sides of the positioning roller 41. The two first electric push rods 44 are respectively installed on both sides of the frame 1 body, and the output ends of the two first electric push rods 44 extend to the bottom of the frame 1. The output ends of the two first electric push rods 44 are fixed with first bases 45. The two ends of the rotating shaft of the positioning roller 41 are respectively rotatably connected to the first bases 45 on the corresponding side.

[0034] Working principle:
[0035] The motor 6 and the winding roller 5 can be used in combination to retract the waterproof cloth. One end of the waterproof cloth is passed around the positioning roller 41 downward and passed through the bottom end of the positioning roller 41. After passing through, it is passed around the direction-changing roller 42 upward and passed through the top end of the direction-changing roller 42. Then, the waterproof cloth is passed through the tension roller 43 downward and passed through the bottom end of the tension roller 43. At this time, the waterproof cloth presents an inverted V shape under the traction of the positioning mechanism. The three rollers are used in combination to position and tension the waterproof cloth. When reeling, the waterproof cloth has sufficient tension and accurate positioning, and is not prone to deviation, stacking, etc.
[0036] The waterproof cloth extending from the bottom end of the tension roller 43 is passed through the gap between the two clamping rollers 31. The distance between the two clamping rollers is adjusted by rotating the screw 33 and cooperating with related components so that the two clamping rollers clamp the waterproof cloth at the same time. When the waterproof cloth moves to one end, its surface will be pressed and smoothed by the two clamping rollers at the same time to remove wrinkles on the surface of the cloth, making it easier to roll up the cloth.
