10. The utility model provides a laser radar survey and drawing's unmanned aerial vehicle's application method which characterized in that: unmanned aerial vehicle using a lidar mapping according to any of claims 1 to 9, comprising the steps of:
s1, when mapping is needed, the unmanned aerial vehicle body (1) flies to a preset position, a first motor (22) works to drive a first connecting shaft (23) to rotate, a second main bevel gear (20) on a second connecting shaft (24) is driven to rotate through transmission among a first belt pulley (7), a transmission belt (8) and a second belt pulley (9), and when the second main bevel gear (20) and a second auxiliary bevel gear (21) are meshed to rotate, a second threaded rod (16) can be driven to rotate, a first moving plate (12) in threaded connection is driven to move through rotation of the second threaded rod (16), and a mounting plate (4) and a laser radar body (19) are sequentially driven to move, so that the laser radar body (19) moves downwards to extend out of a protective shell (3) to facilitate mapping;
s2, in the process that the second threaded rod (16) rotates to drive the laser radar body (19) to move downwards, the first threaded rod (5) is driven to rotate through the engagement between the first main bevel gear (17) and the first auxiliary bevel gear (18), threads on two sides of the first threaded rod (5) are arranged in opposite directions, so that first moving blocks (6) in threaded connection with two sides of the first threaded rod (5) move outwards to drive the connecting plate (11) and the baffle (10) to move outwards, the bottom of the protective shell (3) is opened, and the laser radar body (19) is convenient to extend;
s3, after mapping is completed, the first motor (22) is reversed to drive the laser radar body (19) to move upwards to the inside of the protective shell (3), and the two baffles (10) move to the middle to close the bottom of the protective shell (3), so that the laser radar body (19) is protected;
s4, when the laser radar body (19) is overhauled, a rotating gear (32) fixedly connected to a fixed rod (33) is driven to rotate through rotation of a second motor (31), the rack (34) is driven to move through engagement between the rotating gear (32) and the rack (34), a plug board (28) moves along with the rotating gear, a connecting block (29) slides on a connecting rod (30) which is in sliding connection, so that a movement path of the plug board (28) is conveniently fixed, the plug board (28) is separated from a plug groove (27) which is plugged, and the laser radar body (19) is detached, and the laser radar body (19) is conveniently removed for maintenance and detection;
s5, after maintenance is completed, the top end of the laser radar body (19) is placed in the second groove (26), and the second motor (31) is reversed to drive the plug board (28) to be inserted in the plug groove (27), so that the laser radar body (19) is fixedly installed.
