Abstract
A mining explosion-proof camera relates to a mining instrument, and comprises a glass box (1), a piece of window glass (2), a cylinder body (3), an insulation base (4), an insulation cover (5), a cable gland (6), a pressure plate (7), a drawer plate (8) and a rear cover (9), wherein the glass box (1) is arranged at the front end of the cylinder body (3), the piece of window glass (2) is arranged between the glass box (1) and the pressure plate (7), the rear cover (9) is arranged at the rear end of the cylinder body (3), the cable gland (6) is arranged on the outer side of the rear cover (9), the insulation base (4) and the drawer plate (8) are arranged on the inner side of the rear cover (9), and the insulation cover (5) is arranged on the insulation base (4). The mining explosion-proof camera is stable in performance, can work uninterruptedly, is convenient to mount and can gain a greater visual angle.
Description
Technical field:
The utility model relates to a kind of mining instrument, relates in particular to a kind of flame-proof mine video camera.
Background technology:
Common video camera does not possess explosion-proof function, can not there be the place (as shaft bottom, tunnel, exploiting field etc.) of gas or other damp to use in the down-hole, and the video camera job insecurity of present explosion-proof type, can not be real-time transmitted to the monitor staff to the image that monitors well, just can not in time pinpoint the problems, fail safe is not high.
The utility model content:
The purpose of this utility model provides a kind of explosion-proof camera shooting instrument, and its stable performance, but non-stop run are easy for installation and can obtain bigger visual angle.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it comprises glass case, sight glass, cylindrical shell, insulating base, insulating lid, cable rope head, pressing plate, drawer plate and bonnet, the front end of cylindrical shell is provided with glass case, be provided with sight glass between glass case and the pressing plate, the rear end of cylindrical shell is provided with bonnet, the bonnet arranged outside has cable rope head, and the bonnet inboard is provided with insulating base and drawer plate, and insulating base is provided with insulating lid.
Described cylindrical shell adopts stainless steel material to make.
Shell of the present utility model adopts stainless steel material to make, and has very high intensity and stability, (particularly 316 stainless steels are to be specifically designed to the stainless steel of working in seawater for a long time).Simultaneously, adopt advanced design and advanced processing technology to make, as adopt strict bevel, use homogeneous electrode, carry out inferior arc welding technology, weld entirely, structural design meets the requirement of GB3836.1-2000, GB3836.2-2000, and cable entry adopts the flame-proof type design of standard, meets the regulation of GB3836.1-2000 appendix D3.3.
The utility model is the flame-proof type protective cover of a common video camera, camera lens, and common monitoring camera instrument and camera lens are installed therein, promptly becomes the flame-proof mine video camera.In the flame-proof type protective cover of video camera, common video camera and camera lens are installed on the drawer plate.Drawer plate and protective cover bonnet adopt insulation to be connected, thereby can be because of ground connection in the multiple spot does not form system's electrical interference, and easy for installation.The front end sight glass adopts toughened glass, and its bigger diameter can obtain big visual angle.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
With reference to Fig. 1, this embodiment is by the following technical solutions: it comprises glass case 1, sight glass 2, cylindrical shell 3, insulating base 4, insulating lid 5, cable rope head 6, pressing plate 7, drawer plate 8 and bonnet 9, the front end of cylindrical shell 3 is provided with glass case 1, be provided with sight glass 2 between glass case 1 and the pressing plate 7, the rear end of cylindrical shell 3 is provided with bonnet 9, bonnet 9 arranged outside have cable rope head 6, and bonnet 9 inboards are provided with insulating base 4 and drawer plate 8, and insulating base 4 is provided with insulating lid 5.
Described cylindrical shell 3 adopts stainless steel material to make.
The shell of this embodiment adopts stainless steel material to make, and has very high intensity and stability, (particularly 316 stainless steels are to be specifically designed to the stainless steel of working in seawater for a long time).Simultaneously, adopt advanced design and advanced processing technology to make, as adopt strict bevel, use homogeneous electrode, carry out inferior arc welding technology, weld entirely, structural design meets the requirement of GB3836.1-2000, GB3836.2-2000, and cable entry adopts the flame-proof type design of standard, meets the regulation of GB3836.1-2000 appendix D3.3.
This embodiment is the flame-proof type protective cover of a common video camera, camera lens, and common monitoring camera instrument and camera lens are installed therein, promptly becomes the flame-proof mine video camera.In the flame-proof type protective cover of video camera, common video camera and camera lens are installed on the drawer plate.Drawer plate and protective cover bonnet adopt insulation to be connected, thereby can be because of ground connection in the multiple spot does not form system's electrical interference, and easy for installation.The front end sight glass adopts toughened glass, and its bigger diameter can obtain big visual angle.
