As illustrated in figs. 8-12, road surface breakage of the invention detection camera 2 removes line-scan digital camera 7 and line laser high-energy light source
Outside, a shell is generally also fitted with, the shell includes the box body 24 and lid 25 being adapted, and the lid 25 passes through bolt
It is affixed with box body 24.The end face of box body 24 sets two through holes 26, and two through holes 26 swash with line-scan digital camera 7 and line respectively
Light high-energy light source 8 is engaged, and transmission lens are usually provided with through hole 26, after the completion of box body 24 and lid 25 are combined, structure
Into space in a closed box.The installing plate 27 being engaged with box body 24, the side of the installing plate 27 are set in box body 24
The mounting hole that is engaged with the emitting head of line laser high-energy light source 8 is set, perpendicular curved of opposite side setting and installing plate 27
Plate 28, the bent plate 28 is connected by bolt with installing plate 27.The line-scan digital camera 7 is connected by bent plate 28 with installing plate 27,
The emitting head of the line laser high-energy light source 8 is connected through mounting hole with installing plate 27.The both sides of the installing plate 27 are with setting
Put the bolt connection of floor 29 in 24 liang of madial walls of box body.It is bolted between the installing plate 27 and bent plate 28 of the present invention,
, can be curved by unscrewing or tightening when the light that the light and line laser high-energy light source 8 gathered in line-scan digital camera 7 is launched is misfitted
The bolt that plate 28 is connected with installing plate 27 carries out the fine setting of angle.
Because road surface breakage detects that camera 2 usually requires to carry out certain angular adjustment according to actual conditions, with reference to Figure 13
Shown, more preferable way is that the road surface breakage detection camera 2 is arranged on car body top, the rotation bottom by rotating base 16
Seat 16 includes the rotating part being connected with road surface breakage detection camera 2 and the fixed part being connected with car body, the rotating part and fixation
The first otic placode 17 and the second otic placode 18 that portion is parallel to each other by two pieces respectively are constituted.Two pieces of second otic placodes 18 are connected to two pieces
It is made up of between first otic placode 17 and jointed shaft and is hinged.The opening 19 of one arc is set on first otic placode 17, it is described
Place relative with opening 19 sets a clamping screw 20 vertical with the second otic placode 18, first otic placode 17 on second otic placode 18
With the second otic placode 18 by clamping screw 20 with tight.When needing to carry out angular adjustment, unscrewing clamping screw 20 can be turned
It is dynamic, tighten clamping screw 20 and locking can be completed.Clamping screw 20 has the function of being oriented to and lock concurrently, and simple in construction, is easy to
Operation.
The present invention is obliquely installed due to road surface breakage camera 2, even if after positioning, still with an inclined direction rotating
Trend, therefore, preferably way is, as shown in figure 13, road surface breakage detection camera 2 is provided with below relatively low one end
