Interior is equipped with the first pressure spring 7, and one end of the first pressure spring 7 is fixedly connected with turntable 2, and the other end is fixedly connected with 5 end face of runner, ring
The position for not installing the first pressure spring 7 in shape slot 6 is equipped with the bellows 8 that can be stretched in annular groove 6, and one end of bellows 8 is solid
It is scheduled on the first pressure spring 7 and is fixedly connected with position with 5 end face of runner, the other end stretches out annular groove 6, and the left side of each runner 5 is coaxially solid
Surely have a fixed disk 9, the right side of fixed disk 9 rotate coaxially be connected with one can formed airtight cavity cylinder 10, wave
One end that line pipe 8 stretches out annular groove 6 is connected to through cylinder 10 with cavity, and the upper end in the left side of fixed disk 9 is fixed with the air inlet of cavity
Mouthful, lower end is fixed with the gas outlet of cavity, and the top of fixing axle 1 is equipped with one and loads the water tank 11 with mark function liquid,
The lower end of fixing axle 1 is equipped with the multiple and one-to-one spray head 12 of detection unit, and each spray head 12 is unidirectional through water pipe and water tank 11
Connection, the gas outlet of cavity is connected to water pipe.
In order to realize that bullet block 4 has the trend for being fixed axis 1, each blind hole 3 is interior to be equipped with second pressure spring 13,
One end of second pressure spring 13 other end that is connected with 3 bottom of blind hole is fixed on one end that bullet block 4 is placed in blind hole 3, and bullet block 4 is close to solid
One end of dead axle 1 is dome, and the position that fixing axle 1 is matched with turntable 2 is evenly distributed in multiple matches one by one with multiple bullet blocks 4
The gap 14 of conjunction.
In order to realize the driving of the present apparatus, it is equipped with triangular form bracket at left and right sides of the present apparatus, water tank 11 is fixed on
On triangular form bracket, the rear end of triangular supports 15 is equipped with the fixed ring connected for driving vehicle.
In order to realize the fixation of the first pressure spring 7, one end via pins of first pressure spring 7 are fixed in annular groove 6, another
End is fixed on the end face of runner 5 through U-shaped bar 16, and bellows 8 is also secured on U-shaped bar 16.
In order to realize cavity air inlet and air outlet and water pipe can only one-way flow, the air inlet of the cavity is equipped with
First check valve 17, gas outlet are equipped with second one-way valve 18, and being equipped on water pipe can only be such that liquid flows from water tank 11 to spray head 12
Dynamic third check valve 19.
The notch of the annular groove 6 is shrink mouth shape, and necking width is greater than U-shaped less than the diameter of the first pressure spring 7 and bellows 8
16 diameter of bar.
It can guarantee that liquid is not flowed out from spray head to realize spray head 12 when no gas sprays, the pipe of the spray head upper end
A baffle that can be moved up and down is equipped in road, baffle upper end is equipped with the tension spring that it can be made to reset upwards, and tension spring one end is fixed on
The other end is fixed in the pipeline of spray head upper end on baffle.
Specific work process of the invention is: the present apparatus can be pulled by worker also by the present apparatus through fixation when in use
Ring is fixed on the rear of driving vehicle, places counterweight in the top of triangular supports 15, to guarantee that runner 5 and plane to be detected are kept
