Abstract
The utility model relates to a visible light separated light source illuminating device for an underground TV, which comprises an illumination system, and a video camera electronic circuit. Because the utility model adopts that a light source lamp is away from a video camera and an electronic circuit main body, after power is enlarged, heat which is released by the light source lamp does not effect work of the video camera. The utility model has the advantages of reasonable design, simple operation and use, wide use range of the existing instrument, convenient field use and repair. For the original instrument, a light bulb need to be replaced by practitioners, but at present, operators of any program only need be trained by ten minutes, the light bulb can be just replaced, and the utility model can replace lighting systems of different power and irradiating angles at any time according to on-site requirements. Thus, the utility model reaches the effect of optimum observation image data, and enhances a test success rate.
Description
The utility model relates to the split type light source illuminating apparatus of down-hole, a kind of oil field visible light under-mine TV.
The general scopic illuminating lamp of visible light under-mine TV is to be contained in the same instrument pressure-proof outer cover with camera, the power and the lighting angle of illuminating lamp are restricted, the bulb gross power is during greater than 5W, the heat that bulb sends during work has shortened the operating time of video camera in the time of 120 ℃, lighting angle is greater than more than 30 ℃, light to camera lens, influences cameras view resolution with the light reflection by second reflecting surface of resistance to compression glass lens.
The purpose of this utility model is to provide a kind of visible light under-mine TV split type light source illuminating apparatus, it separates by light-source illuminating system and TV observation main body, the heat that bulb sends when having eliminated work has improved cameras view resolution to the influence of video camera operating time.
The purpose of this utility model is to realize like this, in the pick-up lens outside high pressure leakproof seal plug is housed, power line is drawn from sealing plug, be surrounded by stainless steel tube outward and be connected with lamp shield, in the pick-up lens outside lamp bracket holder is housed also, contains set bolt, the illumination section outside is the pressure-bearing guard shield, the anterior transparent glass of installing, the direct current bulb is installed on inside.
Illumination section promptly can be stretched out and swings different angles according to the down-hole needs, can be placed on again on the lamp bracket holder in the pick-up lens outside.
The utility model is owing to adopted illuminator to leave video camera and electronic circuit main body, so add high-power after, liberated heat does not influence the work of video camera, it is reasonable in design, use simple to operate, enlarged the scope of application of existing instrument, and made things convenient for on-the-spot use to keep in repair, former instrument more changes the bulb and must carry out through the professional, just can change and only need carry out training in 10 minutes now the operator of any program, and can be according to on-the-spot needs, at any time change different power, the illuminator of different irradiating angles reaches the effect of best observed image data, and has improved the test success rate.
Fig. 1 is a structural representation of the present utility model.
Below in conjunction with accompanying drawing the utility model is further specified.
From figure as can be seen, the utility model comprises illuminator and video camera electronic circuit main body two parts, video camera electronic circuit main body is by video camera assembly 1, bearing shell 2, heat absorbing element 3, metal heat preservation bottle 4, joint 5, heat insulation plug 6, sealing ring 7, glass lens 8, pressure-bearing leakproof seal plug 9, pressure cap lamp bracket holder 10, set bolt 11 is formed, bearing shell 2 is connected with joint 5, glass lens 8 is housed on joint 5, and compress by pressure cap lamp bracket holder 10, middle by sealing ring 7 sealings, heat absorbing element 3 is housed in the bearing shell 2 in proper order, metal heat preservation bottle 4, video camera assembly 1, and, on pressure cap lamp bracket holder 10, be separately installed with pressure-bearing leakproof seal plug 9 by heat insulation plug 6 sealings, with lamp bracket set bolt 11; Illuminator comprises cabling stay pipe 12, cylindrical compression spring 13, bulb pressure-bearing protective case 14, direct current bulb 15, transparent glass 16, pressure cap 17, the illumination section outside is a pressure-bearing guard shield 14, the anterior transparent glass 16 of installing, direct current bulb 15 is installed on the inner cylindrical compression spring 13, in the main body outside high pressure leakproof seal plug 9 is housed, power line is drawn from sealing plug 9, is surrounded by cabling stay pipe 12 outward, is connected with pressure-bearing guard shield 14.
The utility model separates the illuminating lamp of visible light under-mine TV from the camera lens main part, process the above seal lamps protective case of a withstand voltage 40Mpa in addition, power line is drawn with high pressure leakproof seal plug from the pick-up lens outside, high pressure stainless steel tube by diameter 5 * 1mm connects with the lamp protective case, the high pressure sealing plug mainly is to prevent that lamp protective case accident when underground work from being hit, and causes high pressure stainless steel tube fracture to leak and damages downhole instrument electronic circuit on the video camera by pressure.Because illuminator has left video camera and electronic circuit main body, so add high-power after, liberated heat does not influence the work of video camera, existing illuminator can increase to 10W--20W, and can change direction, the brightness of illuminator at any time according to down-hole feelings and different purposes.The irradiate light direction is in camera lens the place ahead, and illumination direction can be spent from 90--and 180 degree are optional.
