The following will describe in detail the usage steps of a pneumatic lifting safety billboard convenient to replace with reference to fig. 1 to 7:
when working under normal conditions, natural wind drives the fan 26 to rotate, thereby driving the fan shaft 57 to rotate, thereby driving the wind-driven bevel gear 56 to rotate, thereby driving the ninth bevel gear 53 to rotate, thereby driving the power generation bevel gear 54 to rotate, thereby driving the power generation shaft 52 to rotate, thereby driving the power generator 51 to generate power and store the power in the battery 41, the ninth bevel gear 53 rotates while driving the wind shaft 24 to rotate, thereby driving the third bevel gear 27 to rotate, thereby driving the sixth bevel gear 28 to rotate, thereby driving the seventh bevel gear 30 to rotate, thereby driving the eighth bevel gear 31 to rotate, thereby driving the rotating gear 32 to rotate, thereby driving the rotating toothed ring 33 to rotate to drive the billboard 99 to display slowly by rotation, while the second gear 49 is not driven by the overdrive clutch 400, the low clutch 300 engages and drives the first rotating shaft 20 to rotate, so as to drive the first bevel gear 46 to rotate, but the torque coupling 100 at the front side does not transmit the torque to the winding wheel 45.
When the advertisement board works in a strong wind state, strong wind drives the fan 26 to rotate at a high speed, so as to drive the overspeed driving shaft 75 to rotate at a high speed, so as to drive the overspeed ball 72 to abut against the overspeed driven shaft 71 under the left and right centrifugal force, so as to drive the overspeed driven shaft 71 to rotate, so as to drive the second gear 49 to rotate, so as to drive the first gear 37 to rotate, so as to drive the first bevel gear 46 to rotate, so as to drive the winch shaft 18 to rotate, so as to drive the winch wheel 45 to rotate reversely and release the winch rope 79, the carriage 80 and the advertisement board 99 move downwards to the ground under the action of gravity, so as to prevent the advertisement board from being blown down due to overlarge typhoon, when the carriage 80 moves downwards, the seventh bevel gear 30 and the eighth bevel gear 31 are disengaged, so as to stop the advertisement board 99 from rotating, it is particularly noted that the winding shaft 18 rotates to drive the worm wheel 44 to rotate but cannot drive the worm 39 to rotate, so that the motor 11 cannot rotate and be damaged.
When the advertising board works after strong wind passes, the overspeed clutch 400 is disengaged, the wind shaft 24 rotates to drive the second belt wheel 38 to rotate, so as to drive the first belt wheel 35 to rotate, so as to drive the low-speed driving shaft 61 to rotate slowly, the low-speed ball 62 moves towards the symmetric center under the action of the low-speed spring 63, abuts against the low-speed driven shaft 60 and drives the low-speed driven shaft 60 to rotate, so as to drive the first rotating shaft 20 to rotate, so as to drive the hoisting shaft 18 to rotate, so as to drive the hoisting wheel 45 to rotate positively and tighten the hoisting rope 79, so that the advertising board 99 ascends and returns to the normal working state.
When the advertisement is replaced, the control cabinet 42 is manually used to control the motor 11 to rotate in the forward direction to drive the fourth bevel gear 15 to rotate, so as to drive the fifth bevel gear 17 to rotate, so as to drive the worm 39 to rotate, so as to drive the worm gear 44 to rotate to drive the hoisting wheel 45 to rotate in the reverse direction to release the hoisting rope 79, so that the advertising board 99 descends, and the control cabinet 42 controls the motor 11 to rotate in the reverse direction to drive the hoisting wheel 45 to rotate in the forward direction to tighten the hoisting rope 79, so that the advertising board 99 ascends and returns to the normal working state.
The invention has the beneficial effects that: the pneumatic lifting safety billboard convenient to replace is simple in structure and convenient to use, pneumatic wind power can effectively utilize resources to reduce resource waste, can be automatically lifted according to wind power, effectively solves the problem of casualties caused by collapse due to strong wind damage of an antiaircraft billboard, can be automatically restored after strong wind, is manually controlled to reduce the replacement height of advertisements, can replace advertisements on the ground, reduces the difficulty of advertisement replacement, enables the replacement advertisements to safely, conveniently and slowly rotate, and has the advantages of attracting eyes, enhancing advertisement effect and the like.
