[0033] The second locking mechanism 44 has the same structure as the first locking mechanism 43. The slide rail 46 of the second locking mechanism 44 and the slide rail 46 of the first locking mechanism 43 are symmetrically installed on both sides of the first opening 41 and the first upright 2, and the locking end of the second locking mechanism 44 and the locking end of the first locking mechanism 43 are respectively inserted from the left and right sides of the locking groove 21.

[0034] The unlocking mechanism 5 includes a rotating drum 51, a circular ring 52 and a second spring 53. The rotating drum 51 and the circular ring 52 are both movably sleeved on the outside of the second upright pole 3. The rotating drum 51 is located above the circular ring 52 and the top cover of the top box 4. The rotating drum 51 is connected to the circular ring 52 through a bearing, and the bearing is located on the inner side of the second opening and is rotatably connected to the second opening.

[0035] An outer cylinder 49 movably sleeved on the outside of the first vertical pole 2 is provided at the bottom of the top box 4. Cross bars 491 are fixed on both sides of the outer cylinder 49, and a shutter box 6 is connected below the end of the cross bar 491.

[0036] The top wall 61 of the shutter box 6 is fixedly connected to the cross bar 491, and the four side walls 62 thereof are movably connected to the top wall 61 through a rotating shaft, and the side walls 62 can be opened upward by rotating around the rotating shaft. The shutter box 6 is provided with a telescopic rod 63 and a bottom frame 64, and the bottom frame 64 is provided with two diagonally intersecting support plates 65, and a hollow is formed between the two support plates 65. The side of the bottom frame 64 is an inclined surface. The bottom frame 64 is located at the bottom of the shutter box 6, and one end of the telescopic rod 63 is fixedly connected to the inner top surface of the shutter box 6, and the other end is fixedly connected to the center position of the bottom frame 64. When the telescopic rod 63 is in an extended state, the bottom end of the side wall 62 contacts the side of the bottom frame 64. The meteorological sensor 7 is integrated and installed on the inner top surface of the shutter box 6, and is used to monitor air temperature, air humidity, evaporation, and atmospheric pressure. Ventilation slots are provided on the side walls of the shutter box 6, and the meteorological sensor 7 collects the above-mentioned various meteorological data through the ventilation slots.

[0037] The bottom box 1 is open and has no cover, and a cleaning mechanism and a winding shaft 17 are arranged inside. The cleaning mechanism includes a fixed plate 11, two sleeves 12, two sleeves 13, two third springs 14, a connecting plate 15 and two pressing plates 16. The fixed plate 11 is installed in the middle of the bottom of the bottom box 1, and the sleeves 12 are fixedly installed at both ends of the fixed plate 11 and correspond to the positions of the shutter box 6. The sleeve 13 is movably sleeved on the top of the sleeve 12, and one end of the third spring 14 is connected to the sleeve 13, and the other end is connected to the top of the sleeve 12. An air hole 18 is arranged on the top of the sleeve 13. The two sleeves 13 are connected by a connecting plate 15, and pressing plates 16 are symmetrically arranged at both ends of the connecting plate 15. The winding shaft 17 is located below the fixed plate 11, and one end thereof extends out of the side wall of the bottom box 1. A winding rope 171 is wound on the winding shaft 17.

[0038] The bottom end of the first vertical pole 2 is installed at the middle position of the fixed plate 11, and the second vertical pole 3 is installed at the top end of the first vertical pole 2. Both the first vertical pole 2 and the second vertical pole 3 are hollow structures, and the two outer side surfaces of the first vertical pole 2 located above the first opening 41 are symmetrically provided with lock grooves 21. The first vertical pole 2 is provided with a piston column 22 that can move up and down, and the top of the second vertical pole 3 is provided with a rotating wheel 31. The pull rope 32 passes through the rotating wheel 31, and the top box 4 is connected to the top of the piston column 22 by the pull rope 32. The winding shaft 17 is connected to the bottom end of the piston column 22 through the winding rope 171. The second vertical pole 3 is a hollow cylindrical shape, and the first vertical pole 2 is flat on both sides. The first opening 41 and the outer cylinder 49 are both square structures that match the first vertical pole 2, and the second opening is a circular structure that matches the second vertical pole 3.

[0039] The anemometer 8 and the wind direction meter 9 are both mounted on the top of the top box 4 and are respectively located on both sides of the drum 51. When the top box 4 falls into the bottom box 1, it is located above the cleaning mechanism, and the top surface of the top box 4 is at the same level as the top surface of the side wall of the bottom box 1.

[0040] When this embodiment is in use, under normal conditions, the first locking structure 43 and the second locking structure 44 are inserted into the locking groove 21 to fix the top box 4 on the top of the first vertical pole 2. The wind speed meter 8, wind direction meter 9 and meteorological sensor 7 in the shutter box 6 on the top of the top box 4 monitor various meteorological data in the environment.

[0041] When the weather is windy, the fan blades 56 blow the rotating drum 51 to rotate, and the rotating drum 51 drives the ring 52 to rotate through the bearing. When the wind is light, the rotating drum 51 rotates slowly, and the centrifugal force generated is less than the pulling force of the second spring 53 on the clamping column 55, and the clamping column 55 is not enough to be thrown out. When the wind is strong, the rotating drum 51 rotates faster, and the centrifugal force generated is greater than the pulling force of the second spring 53 on the clamping column 55, and the clamping column 55 will overcome the pulling force of the second spring 53 and be thrown out, and then can be stuck in the clamping groove 471. There are multiple clamping columns 55. During the continuous rotation of the rotating drum 51, the clamping column 55 will be stuck in the clamping groove 471 on the inner side of the slider 47, and the depth of the clamping groove 471 is from shallow to deep, which is also convenient for the clamping column 55 to be stuck. When the rotating drum 51 continues to rotate, the slider 47 will be driven to move through the clamping column 55, and the slider 47 will drive the lock block 46 to move along the slide rail 46, stretching the first spring 48, so that the locking end is away from the lock groove 21, thereby achieving unlocking. After unlocking, the top box 4, the rotating drum 51, the ring 52 and the outer drum 49 will slide down into the bottom box 1. The two sides of the main body of the first vertical rod 2 are flat, the first opening 41 is square, and the rotating drum 15 can rotate outside the first vertical rod 2. The flat shape and the square shape can ensure that the top box 4 will not rotate when sliding. In the process of the top box 4 falling and rising, the friction between the piston column 22 and the first vertical rod 2 will also play a deceleration and buffering role.

[0042] In a normal state, the bottom frame 64 is located below the side wall 62 of the shutter box 6. The side wall 62 of the shutter box 6 naturally hangs down due to its own gravity, and the side walls 62 are closed. When the top box 4 drives the shutter box 6 to fall, the bottom frame 64 first contacts the sleeve 13. In the process of continuing to fall, the sleeve 13 squeezes the intersection of the two support plates 65 of the bottom frame 64, so that the bottom frame 64 moves upward and the telescopic rod 63 shrinks synchronously. The side of the bottom frame 64 is an inclined surface, which squeezes the four side walls 62 through the inclined surface, and the four side walls 62 will turn outward and open with their respective rotating axes, so that gaps are generated between the four side walls 62. Then, in the process of continuing to fall, the bottom of the top box 4 contacts the pressing plate 16 and presses downward. The pressing plate 16 drives the sleeve 13 to move downward through the connecting plate 15. When the sleeve 13 moves downward, it squeezes the third spring 14 and squeezes the air inside it through the air hole 18. The gas discharged from the air hole 18 enters the inside of the venetian box 6 through the hollowing of the bottom frame 64, plays a role of blowing air to the inside of the venetian box 6, and blows out the dust attached to the inside of the venetian box 6 through the gaps between the four walls. When the sleeve 13 moves to the bottom, the top box 4 also falls completely into the bottom box 1, and its top surface is at the same horizontal plane as the top surface of the side wall of the bottom box 1, closing the top opening of the bottom box 1. At this time, the venetian box 6 is stored in the bottom box 1 for protection to prevent flying sand and rocks from entering the inside of the venetian box 6. The wind speed meter 8 and wind direction meter 9 on the top of the top box 4 are still exposed to the outside, which does not affect the collection of wind speed and wind direction.

[0043] When the strong wind stops, the winding shaft 17 can be rotated, and the winding shaft 17 can be set to be manual or electric. The winding shaft 17 winds the winding rope 171, and the winding rope 171 drives the piston column 22 to move downward. The piston column 22 pulls the pull rope 32, thereby driving the top box 4 to rise upward until the lock block 45 is re-engaged in the lock groove 21 under the action of the first spring 48, and the top box 9 is reset. During the rising process, the bottom frame 64 falls and resets due to its own gravity, and the side wall 62 of the shutter box 6 also hangs down and closes again.

[0044] Example 2

[0045] The difference from the first embodiment is that the bottom box 1 is at a certain distance from the ground and does not contact the ground. A through opening extending downward is provided at the bottom of the bottom box 1, and dust falling into the inside of the bottom box 1 can fall through the through opening at the bottom.
