As shown in fig. 2, a first support rod 61 is further rotatably mounted on the lower surface of the guide rod 27, a second support rod 62 is rotatably mounted on one end of the first support rod 61 away from the guide rod 27, and one end of the second support rod 62 away from the first support rod 61 is rotatably connected to the mounting plate 21. The first support rod 61 and the second support rod 62 cooperate to support the rain screen 25.

The two guide rails 22 are rotatably mounted on the side wall far away from one side each other, the side curtain roller 7 is wound with a side rain curtain 71, and one end, far away from the side curtain roller 7, of the side rain curtain 71 is fixedly connected with a falling curtain roller 72 used for pulling the side rain curtain 71 to vertically fall.

As shown in fig. 4 and 5, a first capstan 73 is fixedly mounted on one end of the side curtain roller 7 close to the wall 13, two second capstans 74 are fixedly mounted on the screw shaft 33 of the mounting table 3 far from the worm wheel 43, a cable 75 is wound on the second capstans 74, and one end of the cable 75 far from the second capstans 74 is wound on the first capstans 73.

As shown in fig. 2, the lower surfaces of the two guide rails 22 are respectively provided with an anti-roll bar 76 for supporting the side rain curtain 71 and the guide rails 22, and one end of the anti-roll bar 76 far away from the guide rails 22 is fixedly connected with the wall 13 outside the channel 14.

The implementation principle of the embodiment is as follows:

the supporting columns 1 and the cross beams 11 are used as main stress frames of the warehouse, a ceiling 12 is installed on the cross beams 11, and a wall body 13 is installed on the supporting columns 1, so that a stable warehouse structure is formed. A channel 14 is formed in one wall body 13, and a slidable gate 15 is arranged on the wall body 13 on one side of the channel 14, so that workers and transport vehicles can conveniently enter and exit. In rainy weather, the gate 15 cannot be closed to prevent rain from entering the warehouse for continuous operation.

The rain shielding mechanism 2 is required to block rainwater, and at this time, the driving member 4 is started, and the driving motor 41 is started to drive the worm 42 to rotate, and the screw 33 is driven to rotate through the meshing of the worm wheel 43 and the worm 42. Since the two ends of the screw 33 are rotatably connected to the support block 31 and the mounting table 3, the screw 33 is driven by the driving motor 41 to rotate, and the adjusting ring 34 in threaded engagement therewith drives the guide rod 27 to slide along the guide rail 22, so as to pull the rain shade 25 connected to the guide rod 27. After the rain shielding curtain 25 is unfolded, partial rainwater can be blocked, the possibility that the rainwater enters the warehouse through the channel 14 is reduced, and the influence of the rainwater on sand and soil in the warehouse is reduced.

In the process, the guide rod 27 drives the sliding block 26 to slide in the guide groove 23, and the rain shade 25 pulls the cloth roller 24 to rotate, and when the cloth roller 24 rotates, the spiral spring 53 is driven to deform. The guide rod 27 can also pull the first support rod 61, the first support rod 61 can drive the second support rod 62 which is rotatably connected with the first support rod 61, and the relative position of the first support rod 61 and the second support rod 62 changes along with the movement of the guide rod 27 so as to always support the rain shade 25.

And because the installation rod 29 and the installation hole 28 are in interference fit, different positions of the rain shielding curtain 25 can be clamped in the installation groove 210 by taking down the installation rod 29, namely, the free end part of the rain shielding curtain 25 can be adjusted, so that the rain shielding curtain 25 can be installed according to actual working conditions, and the application range of the rain shielding mechanism 2 is expanded.

Rotation of the screw 33 also rotates the second capstan 74, and rotation of the second capstan 74 pulls the cable 75, and the cable 75 can rotate the side curtain roller 7 by pulling the first capstan 73, thereby releasing the side curtain 71. The side rain curtains 71 and the rain sheltering curtains 25 can be synchronously released, and the side rain curtains 71 vertically fall under the pulling of the falling curtain rollers 72, so that the possibility of rain falling into the warehouse through the passage 14 is further reduced by matching with the rain sheltering curtains 25, and the influence of rain on sand and soil in the warehouse is further reduced.

The anti-roll bar 76 is matched with the guide rail 22, and can support the side rain curtain 71, so that the stability of the side rain curtain 71 is improved. However, after the rain shielding curtain 25 and the side rain curtain 71 are flat and spread, the wind area is large, and the anti-roll bar 76 can improve the stability of the whole rain shielding mechanism 2 and reduce the possibility of looseness thereof.

When there is no rainfall, the rain shades 25 and the side curtains 71 need to be wound up to reduce the effect of the sun on their service life and slow down their aging rate. When the driving motor 41 is rotated reversely, the driving motor 41 drives the lead screw 33 to rotate reversely, so as to pull the guide rod 27 to slide along the guide rail 22 toward the mounting plate 21. In the process, the spiral spring 53 will drive the cloth roller 24 to rotate under the action of the restoring deformation, so as to rewind the flat-spread rain shade 25 onto the cloth roller 24.

And the reverse rotation of screw 33 also rotates side curtain roller 7 via cables 75 on first and second capstans 73, 74 to wind side curtain 71 onto side curtain roller 7.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
