According to 7.0.20 in Industrial television System engineering design Specification GB50115-2009 and 5.4.1 in explosive hazard Environment Power device design Specification GB50058-2014, when a steel pipe wiring mode is used for a cable adopted by an industrial television camera, the sectional area of a conductor of the cable at least reaches 1.5mm2. Because the single-core sectional area of the national standard network cable obviously does not meet the requirement, the traditional configuration scheme of the equipment manufacturer in the current weak current industry is in doubt of the engineering design specification requirement.
Disclosure of Invention
The utility model aims to provide a camera which is suitable for explosion danger environment and adopts optical fiber direct access, so that signal lines outside the explosion-proof protective cover of the camera can transmit video signals by using optical fibers in the whole process, the conversion of electric/optical signals is completed in the explosion-proof protective cover, and an explosion-proof video box does not need to be configured independently near the front end of the camera; the protection function of the conventional optical fiber terminal box on the optical fiber connector is integrated into the protective cover, and a small amount of optical fiber discs are reserved by utilizing the inner space of the protective cover. The equipment configuration and the engineering design specification are better unified.
The utility model discloses an on traditional explosion-proof camera basis, the access mode of video signal line has been improved to with the equipment in the external explosion-proof video equipment case of tradition, rational combination in the space, integrated to in the camera protection casing, make in the explosive environment, the whole optic fibre (light signal) that adopt of signal line outside the explosion-proof protection casing of camera, and do not use the net twine (the conveying signal of telecommunication, need satisfy corresponding line footpath requirement), do not have the suspicion of violation.
The utility model discloses a camera 1, camera lens 2, monitoring power 3, optic fibre transceiver 4, camera explosion-proof protection casing 5, various inside jump (connect) line, optic fibre tail optical fiber 7. The optical fiber connector protection groove 6 is an accessory part integrated in the protection cover 5.
The camera 1 is a network camera, the power is supplied by DC12V, an RJ45 network power port is configured conventionally, and the lens is matched with the camera. The optical fiber transceiver 4 is powered by a DC12V, mainly functions to convert the network electrical signal of the camera into an optical signal for output, one end of the optical fiber transceiver is connected with an optical fiber tail fiber 7, and the other end of the optical fiber transceiver is connected with an RJ45 network electrical port of the camera 1 through a flat network jumper wire 8 (the flexibility is better than that of a common round cable). The monitor power supply 3 is an AC220V input which provides a 2-way DC12V output, the monitor power supply 3 output being connected to the power input of the camera 1 and the fibre-optic transceiver 4 respectively. This explosion-proof protection casing of camera 5 comes based on improving traditional product, except satisfying corresponding explosion-proof grade, has increased optical fiber splice protection groove 6 at explosion-proof protection casing of camera 5, simultaneously on spatial structure, compares traditional product and increases overall dimension slightly, anterior space installation camera 1, rear portion space installation optical fiber transceiver 4 and monitoring power supply 3. The fiber optic transceiver 4 and the monitoring power supply 3 are stacked one on top of the other to save space as much as possible. In actual use, 1 AC220V power supply and 1 single-mode single-fiber butterfly-shaped covered wire optical cable 12 are provided by engineering. Connecting an AC220V power line 11 to the input end of the monitoring power supply 3; the butterfly rubber-insulated optical cable 12 is welded with the built-in optical fiber pigtail 7, and the optical fiber welding head 13 is provided with sleeve protection and is arranged at the optical fiber joint protection groove 6 for fixing. The entire hardware device completes the connection.
Based on the configuration scheme, in an explosive environment, a network cable is not needed to transmit signals outside the camera explosion-proof protective cover 5, the optical fiber is directly connected into the camera, the requirements of engineering design specifications are met, and an explosion-proof video box is not needed to be configured additionally.
In order to realize the direct access of the optical fiber to the camera, firstly, the problems of bending, welding and protection of the optical fiber in the camera protective cover need to be solved; secondly, the problem of centralized installation of a camera, an optical fiber transceiver and a monitoring power supply in a limited space in a protective cover needs to be solved.
The conventional explosion-proof camera protective cover generally does not consider a joint protection component of optical fibers, because the diameter of an outdoor optical cable which is commonly used in the past is thicker, the requirement on the bending radius is larger, a bending coil wire cannot be made in a narrow protective cover, an explosion-proof video box is generally independently arranged, the interior of the explosion-proof video box is used for optical fiber fusion splicing protection and coiling and is provided with equipment such as a power supply and an optical fiber transceiver. With the large-scale application of Fiber To The Home (FTTH) in recent years, the butterfly-shaped rubber-insulated-wire optical cable is widely applied due to small outer diameter and good bending performance. The optical fiber connector protection groove is added on a drawer tray in a camera protection cover in combination with special electrical configuration requirements in an explosion dangerous environment and innovative application of optical cable products, and the optical fiber introduced by external engineering is required to be selected from a butterfly rubber-covered wire optical cable. The external optical fiber is welded with the built-in optical fiber pigtail, and the welding position is provided with sleeve protection and is fixed at the optical fiber joint protection groove.
The traditional explosion-proof camera protective cover is generally in a cylindrical shape, the interior of the traditional explosion-proof camera protective cover is in a drawer type structure, and the tail part of the traditional explosion-proof camera protective cover is provided with a wire inlet hole and a fastening screw. The drawer tray is used for mounting a camera. In order to install the optical fiber transceiver and the monitoring power supply, the front space in the cover is provided with a camera, and the rear space in the cover is provided with the optical fiber transceiver and the monitoring power supply. In order to save space as much as possible, the optical fiber transceiver and the monitoring power supply are stacked up and down. Compared with the traditional explosion-proof protective cover, the diameter of the cover body is basically the same, and the length of the cover body needs to be slightly increased by about 15 cm.
By adopting the scheme, the optical fiber is directly connected into the camera explosion-proof protective cover, and the requirements of relevant design specifications are completely met. In addition, because an independent external explosion-proof video box is not needed, the manufacturing cost is reduced, the whole device is reduced, and the device has great practical value in a narrow space (such as in a coal mine).
