Fig. 2 is a circuit block diagram of the present utility model.
Embodiment
The utility model is described in further detail below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.
As shown in Figure 1 and Figure 2, pipeline is dived and is visited instrument in a kind of missile silo, comprise monitoring unit 1, sniffer 8, wherein, monitoring unit is equipped with display screen 2, positioning device 11, imaging means 9, the lighting set 12 that sniffer is installed by one constitutes and is installed in a bottom that has a dismountable flexible feeler 4 of scale 5 by support 7, monitoring unit by transmission line 3 with sniffer be connected, imaging means is a camera in the present embodiment; At the sniffer front end one protective housing 10 that is used to protect positioning device, imaging means, lighting set is installed, on the top of feeler one steam bubble leveling instrument 6 is installed, its direction of this spirit level is identical with the direction of pick-up lens.
Feeler is shaped on the convenient degree of depth that detects of observing of scale, and feeler is designed to dismountable flexible rod, is convenient to carrying of equipment.
The latent function of visiting the instrument various piece of pipeline is in the missile silo:.
1. imaging means: the function of camera part is to the region probed shooting and converts thereof into electrical signal.
2. lighting set: the function of illumination section is to reliable infrared light and visible light are provided in the region probed.
3. transmission line: the function of transmission line is that the control circuit of monitoring unit inside, the same lighting set of power supply, positioning device, imaging means are coupled together, be lighting set, positioning device, imaging means transmission of electric energy, simultaneously video signal, framing signal are transferred to monitor unit, and guarantee loss of signal minimum in the transmission course.
4. monitor unit: the function of monitor unit is that the clear picture that camera part detects is truly reflected.
Positioning device, there are scale, dismountable feeler, spirit level to be used for the degree of depth of gage well and position, the direction of camera watch region.
Positioning device: present embodiment adopts the laser positioning instrument, the transmitter that utilization can be sent red visible laser realize the making a video recording location at position.
Feeler: feeler is made up of the dismountable flexible rod that has scale of more piece, is used for controlling the height of pick-up lens and well head.
Spirit level plays the direction and the effect perpendicular to the ground of control feeler of indication imaging means.
The transmission means that the video signal of transmitting on the transmission line is selected is the video base band transmission.Video transmission line is selected concentric cable for use.The video base band transmission need not to do any processing to 0～6MHz video baseband signal, by the direct transmission of analogue signal of concentric cable (non-equilibrium).Its advantage is that the loss of short-distance transmission picture signal is little, and system stability is cheap.
For improving the water-proof performance of imaging means, pick-up lens is done water-proofing treating, adopt senior 1.5mm tempering plated film waterproof glass, simultaneously pick-up lens is done antifog processing; For reducing the interference of outer bound pair video signal, the video transmission line in the transmission line adopts many BNC concentric cable docking modes to connect, and the RCA joint is adopted at the video display interface position, and video signal is done anti-interference process; The liquid crystal display of monitor unit utilizes the high anti-reflective liquid crystal screen protection film of primary colors coating transmittance to prevent reflective processing, when increasing image sharpness, also can avoid screen to be drawn damaging and is polluted by spot.The protective housing that the sniffer front end is installed can prevent to collide with other objects in well and damage; In order to prevent that transmission line from twining in well, transmission line is bundled on the feeler.
Spirit level is installed in the top of feeler, its direction is identical with the direction of pick-up lens, can guarantee outside well, just can judge the direction of pick-up lens like this, utilize telescopic feeler control, can detect the caliber of the under ground piping in the missile silo, utilize pick-up lens can judge the trend and the distribution of under ground piping in the well.
