Vertical grooves 7 are provided on the opposite sides of the two support seats 1, and an inflatable air pipe 8 is fixedly connected to the inner lower surface of the vertical groove 7. A slider 9 is provided at the top of the inflatable air pipe 8, and the slider 9 is rotatably connected to the opposite side of the traction rod 6 through a rotating shaft; By inflating or deflating the air pipe 8, the slider 9 is controlled to rise or fall, and the shielding frame 4 can be controlled to move under the pull of the traction rod 6, so as to facilitate the control device to fold or unfold the sunshade and rainproof; The bottom of the support base 1 is fixedly connected with a mounting base 22; Used for splicing and installation with the ground; A plurality of linkage boxes 23 are embedded and installed on the inner rear surface of the shielding frame 4. The inner rear surface of the linkage box 23 is rotatably connected to a shaft column 24 through a rotating shaft. The front end of the shaft column 24 penetrates the front of the linkage box 23 and is fixedly connected to a shielding strip 25. The shielding strips 25 can be rotated, so that a plurality of shielding strips 25 in a flat state can be combined together for shielding. When the external wind force is too strong, the shielding strips 25 can be controlled to move to a vertical state to facilitate ventilation and avoid the problem of damage to the device caused by excessive wind force; A U-shaped lifting rod 26 is arranged above the linkage box 23, the bottom end of the U-shaped lifting rod 26 penetrates into the interior of the linkage box 23 and is slidably connected to the linkage box 23, a rack 27 is fixedly connected to the inner side of the U-shaped lifting rod 26, the rack 27 is slidably connected to the linkage box 23, a gear 28 is fixedly connected to the outer wall of the shaft column 24, the gear 28 is meshedly connected to the rack 27, a spring 29 is fixedly connected between the U-shaped lifting rod 26 and the linkage box 23, and a wedge-shaped pressure block 30 is fixedly connected to the top of the U-shaped lifting rod 26; A U-shaped blocking strip 31 is fixedly connected to the upper surfaces of the two mounting blocks 3, and the inner side of the U-shaped blocking strip 31 contacts the outer side wall of the wedge-shaped pressure block 30; The inflatable air pipe 8 includes a piston tube 801, the piston tube 801 is slidably connected with a piston rod 802, the top of the piston rod 802 is fixedly connected to the bottom of the slider 9, and the piston tube 801 and the ventilation chamber 18 are connected through a ventilation tube 19; When the shielding frame 4 rotates and expands for shielding, the wedge-shaped pressure block 30 will be blocked and squeezed by the U-shaped blocking strip 31. At this time, the U-shaped lifting rod 26 partially retracts into the linkage box 23, and the gear 28 is driven by the rack 27 to rotate the shielding strip 25, so that multiple shielding strips 25 are flat on the inner side of the shielding frame 4 for shielding. When the wind is too strong, the shielding frame 4 is controlled to shield. At this time, the wedge-shaped pressure block 30 loses its obstruction. Under the pull of the spring 29, the U-shaped lifting rod 26 drives the rack 27 to rise. At this time, the shielding strip 25 rotates, so that the inner side of the shielding frame 4 is opened for ventilation, thereby avoiding the problem of excessive wind affecting the shielding, and at the same time avoiding the problem of excessive wind causing easy damage to the device.

At the same time, the cam 41 rotates together with the motor 16, which will squeeze the abutment plate 44, control the piston strip 43 to move repeatedly inside the inflation box 42, repeatedly inflate and exhaust air toward the air outlet 12, so that the arc-shaped sealing strip 38 moves repeatedly along the inside of the air outlet 12, thereby increasing the air outlet range of the blowing hole 39, and then achieving the effect of expanding the air outlet cleaning range; The inside of the installation box 13 is provided with ventilation chambers 18 on both sides of the air inlet chamber 14, and a ventilation pipe 19 is provided between the ventilation chamber 18 and the inflation air pipe 8; The two opposite sides of the two ventilation chambers 18 are fixedly connected with electric push rods 20, and the opposite ends of the output ends of the two electric push rods 20 are fixedly connected with piston plates 21; Two tooth grooves 32 are provided on the outer wall of the exhaust pipe 12, and a rotating connector 33 is fixedly connected to the side of the piston plate 21 close to the electric push rod 20.

The top end of the rack 2 35 passes through the top of the top plate 2 and is meshed with the tooth groove 32.

[0019] By controlling the extension of the electric push rod 20, the piston plate 21 is pushed to slide, and the internal gas of the ventilation chamber 18 is filled into the piston tube 801, so that the piston rod 802 extends. At this time, the traction rod 6 will push the shielding frame 4 to the shielding state, and at this time, under the pulling of the pull rod 34, the rack 2 35 descends, and the air outlet tube 12 is turned to rotate, so that the blowing hole 39 leaks out from the inside of the groove 10, which is convenient for blowing and cleaning. When it is windy, the electric push rod 20 is controlled to shrink, and the ventilation chamber 18 draws away the internal gas of the piston tube 801. At this time, the shielding frame 4 is folded, and the rack 2 35 rises, and the air outlet tube 12 is reset. At this time, the blowing hole 39 is hidden in the groove 10 to avoid blockage problems such as dust.

[0020] Working principle: When in use, the device is installed on the ground through the mounting seat 22, and then the electric push rod 20 is started to extend, and the gas inside the ventilation chamber 18 is filled into the piston tube 801, so that the piston rod 802 is extended, driving the traction rod 6 to push the shielding frame 4 to the shielding state. At this time, the wedge-shaped pressure block 30 is blocked by the U-shaped blocking bar 31, and the rack 27 moves, and the shielding bar 25 is pushed to move through the gear 28, so that it is flat on the inside of the shielding frame 4 to perform shielding work, and then the motor 16 is started to control the rotation of the fan blade 17, so that the air outlet 12 can discharge air to clean the surface of the shielding bar 25, and at the same time, the multiple blowing holes 39 can move repeatedly to increase the blowing range; When encountering strong winds, the motor 16 is turned off and the electric push rod 20 is controlled to retract so that the shielding frame 4 is shielded. At this time, the shielding strip 25 will move to open the shielding frame 4 to facilitate ventilation and avoid damage to the device due to excessive wind.
