These cameras typically feature standard video electrical signal output, video optical signal output, Ethernet electrical signal output, and Ethernet optical signal output, allowing users to choose the appropriate output method based on their needs. This equipment boasts advantages such as small size, light weight, high definition, and long transmission distance.

[0003] Currently, the working environment of coal mining machines underground is extremely harsh, with a large amount of coal dust, water vapor and other dangerous factors. At the same time, the coal mining machine will move and rotate frequently during operation. In addition, with the current development trend of intelligent coal mining, the entire coal industry is moving towards intelligent and automated development. The accurate acquisition of on-site conditions is particularly important. When the existing structure camera is installed at the rocker arm of the coal mining machine, due to factors such as angle, it must be deliberately adjusted, which results in the camera harness being exposed on the outside, posing a significant safety hazard. Utility Model Content

[0004] To address the issue that when structural cameras are installed at the rocker arm of a coal mining machine, the angle and other factors necessitate deliberate adjustments that expose the camera wiring harness on the outside, posing a significant safety hazard, this application provides a mine-use explosion-proof camera with back-out wiring.

A cover plate 9 is provided on the upper part of the housing 1. A cable outlet tube 8 is opened in the middle of the cover plate 9. The LED light board 6, LED heat sink 7, fixing plate 5, rubber pad 4, explosion-proof glass 3 and copper pad 2 are sequentially installed at the supplementary light position inside the housing 1 to facilitate the fixing and protection of the supplementary light.

[0029] Please refer to Figure 1 and Figure 3 A sealing groove is provided at the joint between the housing 1 and the cover plate 9, and a silicone sealing ring 10 is installed inside the sealing groove to ensure reliable operation of the camera in the humid, flammable and explosive environment of the mine. A protective net 11 is installed on the housing 1 outside the supplementary light. A front plate 12 and a rear plate 16 are respectively installed at both ends of the support plate 14. The supplementary light protective net 11 installed on the outside of the housing 1 can enhance the equipment's anti-vandalism capability, protect the integrity of the equipment, and reduce the scattering and reflection of the supplementary light to a certain extent, thereby improving the accuracy of illumination. The installation of the protective net greatly improves the reliability, safety and stability of the equipment, ensuring the normal operation of the equipment in the harsh environment of the mine.

[0030] Please refer to Figure 3 Side plates 15 are installed on both sides of the support plate 14. A downwardly extending ear plate 13 is installed at one end of the side plate 15. A pair of side plates 15 are fixed to the support plate 14 and the front and rear end plates respectively. After connecting the front and rear end plates, a small part of the side plates 15 extends out. Threaded holes and fixing bolts for fixing the rocker arm of the coal mining machine are provided on the extended part. The front end of the side plate has a downwardly extending ear plate 13. The ear plate 13 is used to be bolted to the corresponding position of the coal mining machine. Each plate is made of 5mm thick stainless steel plate and the plates are welded together to form a whole.

[0031] Please refer to Figure 1 and Figure 3 The extension line of the cover plate 9 along its length forms an angle greater than 0 degrees and less than 30 degrees with the central axis of the camera. The central axis of the cable outlet tube 8 is perpendicular to the cover plate 9. The housing 1 of the camera forms a 25-degree angle. The cable outlet tube 8 is installed at the cover plate 9. This design meets the monitoring requirements of the roller when the equipment is installed at the rocker arm. The electronic components in the circuit board assembly all have quick-connect connectors. The quick-connect function of the electronic components and the universal installation of the cable outlet tube 8 enable the camera to have good quick installation and maintainability.

[0032] The implementation principle of a mine-use explosion-proof camera with back-out cable according to an embodiment of this application is as follows: LED light board 6 is fixed to LED heat sink 7 on fixed pressure plate 5 by screws. In addition to fixing LED light board 6, fixed pressure plate 5 also has the function of pressing glass. LED light 6, LED heat sink 7, fixed pressure plate 5, rubber pad 4, explosion-proof glass 3, and copper pad 2 are installed in sequence at the supplementary light mounting position on the camera housing 1. The electronic components are all quick-connect connectors, which are led out from the universal cable tube 8 of the device. A sealing groove is opened between the housing 1 and the back cover plate 9, and the middle is an explosion-proof joint surface. A silicone sealing ring 10 is installed in the sealing groove to meet the waterproof and dustproof requirements of the device.

[0033] A protective net 11 is installed at the supplementary light to improve its safety. When the equipment is working in the mine, the supplementary light provides illumination for the equipment in the dark environment. The back-out cable design greatly improves space utilization and makes the wiring neater. At the same time, the cable tray 8 installed on the back cover plate 9 also enhances the protection of the cable bundle. The back-out cable structure design allows the equipment to monitor the working condition of the drum and the condition of the coal wall at the optimal position and angle of the drum-type coal mining machine rocker arm.
