Pneumatic cavity is horizontally disposed with, described pore is divided into the first pore, second pore, be located at two ends, pneumatic cavity top respectively, described source of the gas line to be positioned on the upside of bus compartment top wall and to be passed down through bus roof, described solenoid directional control valve is located on described source of the gas line, source of the gas line is by being divided into two parts after solenoid directional control valve, connect the first pore respectively, second pore, air rammer to be located in pneumatic cavity and to be positioned at the first pore, between second pore, described air rammer both sides are located at by sealing ring, piston rod one end is connected with described air rammer, the other end passes pneumatic cavity and connects camera erecting bed, camera is fixed on camera erecting bed.
Described piston rod, air rammer, camera erecting bed, sealing ring form a pneumatic conveyor, are horizontally placed on bus compartment top.By the pneumatic conveyor using piston rod, air rammer, camera erecting bed, sealing ring to form, add and be fixed on the activity that camera installs the camera on slide unit, expand monitoring range, eliminate monitoring dead angle, reduce the quantity of camera, reduce cost.
Further, described source of the gas line is connected to bus air compressor.Without newly added equipment, reduce cost.
Again further, described camera is hemisphere wide-angle type.The fixed installation manual adjustments angle camera that use cost is lower, further reduces costs.
Again further, the junction of described piston rod and camera erecting bed is provided with the buffering shockproof part that elastomeric material is made.Reduce camera collision stressed, protect camera, extend its useful life.
Again further, described piston rod is two.Camera erecting bed is connected more firm with it.
By above-mentioned disclosure, beneficial effect of the present invention for: by the pneumatic conveyor using piston rod, air rammer, camera erecting bed, sealing ring are formed, add and be fixed on the activity that camera installs the camera on slide unit, expand monitoring range, eliminate monitoring dead angle, reduce the usage quantity of camera, reduce cost.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is part section structural representation of the present invention, eliminates part-structure in figure.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
As shown in Figure 1, a kind of safety monitoring equipment used for buses, comprises camera 1, piston rod 2, air rammer 6, source of the gas line, pore 3, camera erecting bed 4, sealing ring 5, solenoid directional control valve, pneumatic cavity 7;
Pneumatic cavity 7 is horizontally disposed with, described pore is divided into the first pore 3, second pore 8, be located at two ends, pneumatic cavity 7 top respectively, described source of the gas line to be positioned on the upside of bus compartment top wall and to be passed down through bus roof, described solenoid directional control valve is located on described source of the gas line, source of the gas line is by being divided into two parts after solenoid directional control valve, connect the first pore 3 respectively, second pore 8, air rammer 6 to be located in pneumatic cavity 7 and to be positioned at described first pore 3, between second pore 8, described air rammer 6 both sides are located at by sealing ring 5, piston rod 2 one end is connected with described air rammer 6, the other end passes pneumatic cavity 7 and connects camera erecting bed 4, camera 1 is fixed on camera erecting bed 4.
Described piston rod 2, air rammer 6, camera erecting bed 4, sealing ring 5 form a pneumatic conveyor, are horizontally placed on bus compartment top.During use, solenoid directional control valve is energized, gas circuit is connected, compressed air enters pneumatic cavity 7 through source of the gas line by the first pore 3 by solenoid directional control valve, be located at the air rammer 6 pressurized motion in pneumatic cavity 7, and drive the piston rod 2 being connected to air rammer 6, and the camera erecting bed 4 being connected to piston rod 2 other end moves in the same way; When needing described pneumatic conveyor to do counter motion, the break-in of electromagnetic switch threshold switch, compressed air enters pneumatic cavity 7 through source of the gas line by the second pore 8 of the other end by solenoid directional control valve, make the counter motion of air rammer 6 pressurized and drive the piston rod 2 being connected to air rammer 6, and being connected to camera erecting bed 4 counter motion of piston rod 2 other end; When camera 1 moves to the position of required monitoring, stop powering to solenoid directional control valve, solenoid directional control valve cuts out, and gas circuit is interrupted, described pneumatic conveyor stop motion, therefore described camera 1 can need to do discontinuity reciprocating motion according to monitoring.
Further, described source of the gas line is connected to bus air compressor.Without newly added equipment, reduce cost.
Further, described camera 1 is hemisphere wide-angle type.The fixed installation manual adjustments angle camera that use cost is lower, further reduces costs.
