Description

Technical Field

[0001] This utility model relates to the field of coal mine monitoring technology, specifically a coal mine monitoring camera with a built-in supplementary lighting structure. Background Technology

[0002] Coal mines, as crucial areas for human extraction of coal resources, are mainly classified into two types based on the distance between the coal seam and the surface: underground coal mines and open-pit coal mines. In underground coal mines, because the coal seam is far from the surface, it is usually necessary to excavate tunnels underground for coal mining operations; while open-pit coal mines are suitable for situations where the coal seam is closer to the surface, in which case the surface soil layer can be directly stripped to extract the coal. In the daily operation of coal mines, safety assurance and efficient management are crucial aspects.

[0003] To achieve this goal, a large number of surveillance cameras are installed inside coal mines. These cameras are like the "eyes" of the coal mine, monitoring various situations inside the mine in real time. They play an irreplaceable role in timely detection of safety hazards, standardization of work procedures, and protection of personnel safety.

[0004] However, the unique environment inside mines presents numerous challenges to the normal operation of surveillance cameras. Poor lighting conditions are one of the key factors affecting monitoring effectiveness. Mine interiors typically lack natural light, and dust generated during operations can further reduce ambient brightness, resulting in blurry images and loss of detail from the surveillance cameras, failing to meet actual monitoring needs. To improve the monitoring performance of cameras inside mines, supplementary lighting has become an indispensable auxiliary device. Supplementary lighting provides additional illumination to the monitored area, making the monitored images clearer and brighter, thereby improving the accuracy and reliability of monitoring.

[0005] However, existing supplementary lighting for mine surveillance cameras on the market has significant limitations in terms of functionality and structure. Most of these lights use fixed installation methods and simple lighting designs, making them unable to be freely adjusted according to the actual monitoring angle and height of the surveillance cameras. In practical applications, due to the complex and varied layout within mines, the installation positions and angles of surveillance cameras differ greatly. Fixed supplementary lighting is insufficient to meet these diverse needs, leading to insufficient lighting or overexposure in some areas, failing to provide ideal illumination conditions for the surveillance cameras, and consequently affecting the performance and effectiveness of the entire monitoring system.

The strip is fixedly connected to the bottom end of the recess and has several positioning holes. A positioning rod is fixedly connected to one side of the bottom end of the mounting block, and the end of the positioning rod away from the mounting block is movably inserted into the corresponding positioning hole.

[0011] Preferably, the limiting block is configured with an arc shape that adapts to the outer wall of the rotating column.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-5 The present invention provides the following technical solution: Example 1: A coal mine monitoring camera with a built-in supplementary lighting structure includes a mounting base 1, a mounting plate 5, a pulling assembly 7, and two positioning assemblies 9. The camera body 2 is fixedly connected to the bottom of one side of the mounting base 1, and a base 3 is fixedly connected to the top of the mounting base 1. A groove 11 is provided on the upper end of the base 3, and a rotating column 4 is located directly above the base 3. The bottom end of the rotating column 4 is rotatably connected to the groove 11. One side of the bottom of the mounting plate 5 is fixedly connected to the top of the rotating column 4. An opening 6 is provided on the side of the mounting plate 5 away from the rotating column 4. A supplementary light 10 is rotatably connected to the opening 6 via a rotating shaft. The supplementary light 10 rotates within the groove 11 of the base 3 via the rotating column 4. Combined with the ingenious design of the top column 71, pull rod 72, recessed frame 73, and moving block 74 in the pulling assembly 7, the supplementary light 10 can flexibly rotate according to the monitoring angle of the camera body 2, ensuring that the monitored area always receives sufficient and uniform illumination. This effectively solves the problem of blurred monitoring images and loss of details due to insufficient light, greatly improving the accuracy and reliability of monitoring. Pull assembly 7 is set on the upper end of mounting plate 5. Pull assembly 7 includes top column 71, pull rod 72, recessed frame 73 and moving block 74. Recessed frame 73 is fixed on the upper end of mounting plate 5. Moving block 74 is movably sleeved on recessed frame 73. Top column 71 is vertically fixed to the tail of supplement light 10. One end of pull rod 72 is rotatably connected to top column 71. The other end of pull rod 72 is rotatably connected to one side of moving block 74. Pushing moving block 74, moving block 74 pulls top column 71 through pull rod 72, thereby causing supplement light 10 to rotate, thereby adjusting the illumination angle of supplement light 10. Two positioning components 9 are located on both sides of the recess 73. Each positioning component 9 includes a mounting block 91, a positioning rod 92, an insert rod 93, a spring 94, a strip 95, and several positioning holes 96. One end of the insert rod 93 is movably inserted into one side of the movable block 74, and the other end of the insert rod 93 is fixedly connected to the mounting block 91. The spring 94 is fixed between the mounting block 91 and the movable block 74 and is sleeved around the insert rod 93. The strip 95 is fixedly connected to the bottom of the recess 73 and has several positioning holes 96. The positioning rod 92 is fixedly connected to one side of the bottom of the mounting block 91. The end of the positioning rod 92 away from the mounting block 91 is movably inserted into the corresponding positioning hole 96. The positioning rod 92 is movably inserted into the corresponding positioning hole 96, thereby ensuring the stability of the movable block 74 and thus ensuring the stability of the angle adjustment of the supplementary light 10. The bottom of the rotating column 4 is set in a "T" shape, and the bottom of the rotating column 4 is adapted to the groove 11. Several balls 12 are embedded in the inner wall of the groove 11. The balls 12 are all connected to the outer wall of the bottom of the rotating column 4 by rolling. By rolling the balls 12 against the inner wall of the groove 11, it is easier to rotate the rotating column 4. Both positioning rods 92 are designed in the shape of hooks, and the two positioning rods 92 are adapted to several positioning holes 96 to ensure that when the mounting block 91 is pressed, the positioning rods 92 will separate from the positioning holes 96, thereby releasing the restriction on the moving block 74.

[0017] In use, the staff determines the approximate angle required for the supplementary light 10 based on the area to be monitored by the camera body 2, presses the two mounting blocks 91, and when the two mounting blocks 91 move closer to the moving block 74, they drive the two insert rods 93 to be inserted into both sides of the moving block 74, and simultaneously squeeze the two springs 94. The two positioning rods 92 also separate from the positioning holes 96 at the same time. After the positioning rods 92 are completely separated from the positioning holes 96, the moving block 74 on the recess 73 is manually moved. Since one end of the pull rod 72 is rotatably connected to one side of the moving block 74, and the other end is rotatably connected to the top column 71 that is vertically fixed at the tail of the supplementary light 10, as the moving block 74 moves, the pull rod 72 will drive the top column 71, thereby causing the supplementary light 10 to rotate around the pivot in the opening 6 of the mounting plate 5. During the movement of the movable block 74, staff can observe the illumination direction of the supplementary light 10 in real time. When the illumination angle of the supplementary light 10 meets the lighting requirements of the monitored area, the movement of the movable block 74 is stopped, and the two mounting blocks 91 are released. The two mounting blocks 91 move away from the movable block 74 due to the restoring force of the spring 94. One end of the two positioning rods 92 is then inserted into the corresponding positioning holes 96, thereby restricting the movable block 74 and the supplementary light 10. The supplementary light 10 can rotate flexibly according to the monitoring angle of the camera body 2, ensuring that the monitored area always receives sufficient and uniform illumination, effectively solving the problem of blurry monitoring images and loss of details due to insufficient light. In subsequent monitoring, the monitoring image is clear and stable, greatly improving the accuracy and reliability of monitoring and providing strong support for the safe production of coal mines.

[0018] Example 2, the technical solution of which differs from Example 1 includes: a limiting component 8 is also provided on one side of the rotating column 4. The limiting component 8 includes a bolt 81, a fixing block 82, two guide rods 83 and a limiting block 84. The fixing block 82 is fixed to the upper end of the mounting base 1. The bolt 81 is threadedly connected to the fixing block 82. The end of the bolt 81 is rotatably connected to the limiting block 84. The limiting block 84 corresponds to the rotating column 4. Both guide rods 83 are movably sleeved with the fixing block 82. One end of both guide rods 83 is fixedly connected to the limiting block 84. The limiting block 84 restricts the rotating column 4 to prevent the rotating column 4 from rotating on its own and ensures the stability of the rotating column 4. The limiting block 84 is designed with an arc shape that matches the outer wall of the rotating column 4 to ensure the limiting effect of the limiting block 84 on the rotating column 4.

[0019] In use, by rotating the bolt 81, since the bolt 81 is threadedly connected to the fixing block 82, and the end of the bolt 81 is rotatably connected to the limit block 84, the two guide rods 83 are movably sleeved with the fixing block 82 and one end is fixedly connected to the limit block 84. Rotating the bolt 81 will drive the limit block 84 to move along the guide rod 83, adjusting the limit block 84 to a suitable position so that it fits tightly against the outer wall of the rotating column 4. The limit block 84 is set with an arc shape that matches the outer wall of the rotating column 4, thereby ensuring the stability of the rotating column 4, and thus ensuring the stability of the angle adjustment of the supplementary light 10.
