Principle of operation

When the lifting hook of tower crane reciprocated, the pulley on the lifting hook drove lifting hook pulley adapter 12 and provides power, lifting hook pulley adapter 12 drove power output shaft 23 and rotates, power output shaft 23 drove one-way transmission shaft 24 and rotates, one-way transmission shaft 24 drove axis of rotation 25 and rotates, axis of rotation 25 drove turbofan 28 and rotates, one-way transmission shaft 24 drove axis of rotation 25 when the lifting hook was down, one-way transmission shaft 24 drove axis of rotation 25 and rotates when the lifting hook was ascending, the water smoke and the dust that the camera met when the lifting hook was down are the most like this, equipment pertinence is handled, simultaneously one-way rotation also makes things convenient for subsequent turbofan 28 work.

When the turbofan 28 rotates, air is sucked from the outside after being filtered by the filter plate 27, the air is pressed into the expansion ball 31 through the guide pipe 29, the air is continuously flushed into the expansion ball 31 to enable the expansion ball 31 to start to expand, the expansion is stopped when the expansion ball expands to a certain size, the pressure in the expansion ball 31 starts to rise, when the pressure in the expansion ball 31 is larger than the pressure valve 34, the air flows into the sliding cavity 32 and is blown into the lower part through the vent hole 39, and finally is blown onto the surface of the light-transmitting plate 22 through the slot 55, the air guide hole 59 and the blowing-off air transmission hole 60 to enter the mounting box 15, and finally the air is blown onto the surface of the light-transmitting plate 22 through the air injection holes 52, so that water vapor and attached dust on the surface of the light-transmitting plate 22 are blown away, and more dust is prevented from being attached to the light-transmitting plate 22.

When the hook moves downwards for a longer time, the surface of the light-transmitting plate 22 is not cleaned enough only by the compressed gas, so when the compressed gas passes through the vent hole 39, the blade 43 is triggered to rotate, the blade 43 drives the rotating shaft 42 to rotate, the rotating shaft 42 drives the pull rope reel 44 to rotate, the pull rope reel 44 drives the torsion spring 45 to accumulate force, the pull rope reel 44 rotates to pull the pull rope 41, the first slide block 38 is driven to move, so that the vent hole 39 on the first slide block 38 is aligned with the installation shell 46, at the moment, the slide block 36 can not be pushed downwards continuously to move the slide block 36 downwards, the slide block 36 pulls the slide block return spring 37, when the slide block 36 moves downwards to the bottom of the sliding cavity 32, the switching push block 40 is inserted into the second slide block 57 to push the second slide block 57, so that the air guide hole 59 is aligned with the scraping air conveying pipe 49, and the slot 55 pushes the stop 47 open, so that the air flow enters the air guide hole 59 through the slot 55 under the condition that the slide block 36 is kept at the bottom of the sliding cavity 32, the air guide holes 59 and the scraping air conveying pipes 49 enter the pneumatic telescopic pipe 50, the pneumatic telescopic pipe 50 is pushed to extend out of the mounting box 15, the pneumatic telescopic pipe 50 moves the scraping plates 16 along the guide rods 17, and the water stains, dust and mud on the surface of the light-transmitting plate 22 can be scraped by the movement of the scraping plates 16, so that the light-transmitting plate 22 is further cleaned.

The speed of movement of the blade 16 will be relatively fast past under the camera 21 so that the cleaning action of the light-transmitting panel 22 will not affect the image formation of the camera 21 at all times.

After the scraper 16 abuts against the fixed plate 14, if the lifting hook is further moved downwards, the pressure of air in the pneumatic telescopic pipe 50 exceeds the pressure release valve 51, the air is sprayed out through the cleaning nozzle 54 to blow and clean the part scraped off from the surface of the scraper 16, manual re-cleaning is reduced as much as possible, high automation is realized, when the lifting hook does not move downwards any more, the pneumatic telescopic pipe return spring 61 drives the pneumatic telescopic pipe 50 to return, the pneumatic telescopic pipe 50 drives the scraper 16 to return, the sliding block return spring 37 drives the sliding block 36 to return, the switching push block 40 leaves the second sliding block 57, the second sliding block return spring 58 drives the second sliding block 57 to return, redundant air in the sliding cavity 32 is slowly discharged through the damping pressure release valve 33, and the damping pressure release valve 33 is also slowly discharged outwards during work and only does not influence the work of other parts.

Torsion spring 45 drives stay cord spool 44 to reset, stay cord spool 44 loosens stay cord 41, reset ejector pad 35 inserts in the sliding block 36 at last, it resets to start first slider 38, dog 47 is pushed back by dog top spring 48 after breaking away from with the contact of kicking out piece 56, when no longer continuing to rush into gas in expansion ball 31, expansion ball 31 begins to restore, press the gas in expansion ball 31 back into the casing 26 of breathing in, discharge through filter 27 at last, carry out a reverse cleaning to filter 27, blow open the impurity on the filter 27.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
