[0027] In this embodiment, through the arrangement of the base 1, the rod body 2, the support rod 3 and the camera 11, the rod body 2 is vertically and fixedly installed on the base 1. By adjusting the height of the support rod 3 on the rod body 2, the installation height of the camera 11 can be adjusted according to the shooting requirements.

[0028] In this embodiment, through the arrangement of the mounting cylinder 4, the rotating rod 5, the cavity 6, the groove body, the connecting rod 7, the clamping column 8, the fixing rod 9 and the mounting bracket 10, the rotating rod 5 is connected to the center of the bottom of the mounting cylinder 4 through a bearing seat. The bottom end of the rotating rod 5 extends out of the mounting cylinder 4. The clamping column 8 is fixedly connected to the connecting rod 7, the fixing rod 9 is fixedly connected to the connecting rod 7, and the mounting bracket 10 is fixedly connected to the fixing rod 9. When installing the camera 11, the connecting rod 7 is inserted into the cavity 6, and through the rotation of the connecting rod 7, the clamping column 8 is driven in the groove body so that the clamping column 8 is completely clamped into the corresponding groove body, realizing the clamping and fixing of the connecting rod 7 in the cavity 6, and thus completing the installation of the camera 11 on the support rod 3. When the camera 11 is damaged and needs to be repaired or replaced, by rotating the connecting rod 7 to disengage the clamping column 8 from the groove body, the connecting rod 7 can be taken out of the cavity 6, and then the camera 11 can be removed.

[0029] In this embodiment, through the arrangement of the mounting assembly, the support rod 3 is fixedly connected to the mounting assembly, and through the connection between the mounting assembly and the rod body 2, the fixing of the support rod 3 on the rod body 2 can be completed.

[0030] In this embodiment, as Figure 6 shown, the groove body includes a rotating groove 200 and a clamping groove 201, and a spring 203 for pushing the clamping column 8 to be clamped tightly in the clamping groove 201 is provided in the cavity 6.

[0031] In this embodiment, through the arrangement of the rotating groove 200, the clamping groove 201 and the spring 203, when installing the camera 11, the connecting rod 7 is inserted into the cavity 6, and the connecting rod 7 is rotated to drive the clamping column 8 to rotate in the rotating groove 200. When the clamping column 8 rotates to above the clamping groove 201 through the rotating groove 200, the spring 203 pushes the clamping column 8 to be clamped tightly in the clamping groove 201, and thus the installation of the camera 11 can be completed; when the camera 11 is damaged and needs to be repaired or replaced, the connecting rod 7 is pushed upward to compress the spring 203, and the connecting rod 7 is rotated to disengage the clamping column 8 from the clamping groove 201, and then the camera 11 can be removed, and the operation is simple and time-saving.

[0032] In this embodiment, the rotation of the rotating rod 5 can drive the connecting rod 7 to rotate, and further drive the camera 11 to rotate circumferentially in the horizontal direction, so as to increase the shooting angle of the camera 11.

[0033] Please refer to Figures 1 - 6, in this embodiment, the installation component includes a clamp 100 that is oppositely arranged on the rod body 2 and can hold the rod body 2 tightly or disengage from the rod body 2. One end of the clamp 100 is provided with a connection frame 101 connected to the support rod 3. One end of the clamp 100 extends into the connection frame 101. A screw rod 102 that can rotate and thread through one end of the clamp 100 is arranged in the connection frame 101. The other end of the clamp 100 forms an installation part 104, and the installation parts 104 are connected to each other through bolts 103.

[0034] In this embodiment, through the settings of the clamp 100, the connection frame 101, the screw rod 102, the bolt 103, and the installation part 104, when the support rod 3 is fixedly installed on the rod body 2, the bolt 103 can be removed first. Since the connection frame 101 limits one end of the clamp 100, and the threads provided on the screw rod 102 that cooperate with one end of the clamp 100 are arranged in a reverse symmetric manner, by rotating the screw rod 102, the oppositely arranged clamps 100 can be driven to move away from each other in the connection frame 101. Then, the rod body 2 is sleeved between the clamps 100, and then the screw rod 102 is rotated to make the clamps 100 approach each other and hold the rod body 2 tightly. Finally, the installation parts 104 are connected through the bolts 103 to realize that the clamp 100 is clamped on the rod body 2, and thus the installation of the support rod 3 on the rod body 2 can be completed.

[0035] Please refer to Figures 1 - 6 , in this embodiment, a motor 300 for driving the rotating rod 5 to rotate is arranged in the installation cylinder 4, and heat dissipation holes for dissipating heat from the motor 300 are arranged at the bottom of the installation cylinder 4.

[0036] In this embodiment, through the settings of the motor 300 and the heat dissipation holes, the output end of the motor 300 is fixedly connected to the rotating rod 5. The motor 300 can drive the rotating rod 5 to rotate, thereby driving the camera 11 to rotate 360 degrees in the horizontal direction. The heat dissipation holes can dissipate heat from the inside of the installation cylinder 4 to avoid affecting the operating performance of the motor 300 due to excessive temperature.

[0037] Combined with Figure 7 As shown, in this embodiment, rotating shafts 301 that are oppositely arranged on both sides of the installation frame 10 and are connected to the camera 11 and can rotate are provided, and an electric push rod 302 for driving the camera 11 to rotate up and down is arranged on the installation frame 10.

[0038] In this embodiment, through the setting of the rotating shaft 301, one end of the rotating shaft 301 is rotatably connected to the installation frame 10, and the other end is fixedly connected to the housing of the camera 11. Thus, the rotational installation of the camera 11 on the installation frame 10 is preferably realized;

[0039] Specifically, as Figure 7As shown in the figure, the electric push rod 302 is fixedly connected to the mounting bracket 10. The output end of the electric push rod 302 is hinged to a hinge seat 13. A slide rail 14 is provided on the upper side wall of the housing of the camera 11. The hinge seat 13 is slidably connected to the slide rail 14. Thus, when the electric push rod 302 works, it can drive the hinge seat 13 to slide on the slide rail 14, and then drive the camera 11 to rotate around the rotating shaft 301, so that the camera 11 can be adjusted in the vertical direction to face, enabling the camera 11 to perform multi-angle real-time monitoring of the mining area to timely detect potential safety hazards in the mining area.

[0040] Please refer to Figures 1 - 6 In this embodiment, a groove 400 is provided inside the clamp 100, and a plurality of limiting blocks 401 which are evenly distributed on the rod body 2 and cooperate with the groove 400 to prevent the clamp 100 from sliding up and down are provided.

[0041] In this embodiment, through the arrangement of the groove 400 and the limiting blocks 401, the limiting blocks 401 are fixedly connected to the rod body 2. When the support rod 3 is fixedly installed on the rod body 2, the groove 400 on the clamp 100 is aligned with the limiting blocks 401 for clamping, which can prevent the clamp 100 from sliding up and down, making the installation of the support rod 3 on the rod body 2 more stable. At the same time, there are multiple limiting blocks 401 on the rod body 2 and at different heights, so that the support rod 3 can be installed at different height positions on the rod body 2 according to the monitoring requirements of the camera 11.

[0042] Please refer to Figures 1 - 6 In this embodiment, fixing holes 12 for fixing the base 1 are provided at the four corners of the base 1.

[0043] In this embodiment, through the arrangement of the fixing holes 12, when the base 1 is fixed, the base 1 can be fixed by the cooperation of expansion bolts with the fixing holes 12 and the installation ground.

[0044] Working principle: First, install the camera 11 on the rotating rod 5, insert the connecting rod 7 into the cavity 6, then rotate the connecting rod 7 to drive the clamping post 8 to rotate in the rotating groove 200. When the clamping post 8 rotates through the rotating groove 200 above the clamping groove 201, the clamping post 8 is pushed by the spring 203 to be clamped in the clamping groove 201, and the installation of the camera 11 on the rotating rod 5 can be completed. Then, the bolt 103 can be removed first, and then rotate the screw rod 102 to drive the relatively arranged clamps 100 to move away from each other. Then, place the limiting block 401 at an appropriate height on the rod body 2 into the groove 400 of the clamp 100, and then rotate the screw rod 102 to make the clamps 100 approach each other to tightly hold the rod body 2. Finally, connect and install the installation part 104 through the bolt 103 to realize that the clamp 100 is clamped on the rod body 2, and the installation of the support rod 3 on the rod body 2 can be completed, and further the installation of the camera 11 on the rod body 2 can be completed. Through the drive of the motor 300 and the electric push rod 302, the camera 11 can be driven to perform real-time monitoring of the mining area from multiple angles; when the camera 11 is damaged and needs to be repaired or replaced, push the connecting rod 7 upward to compress the spring 203, so that the clamping post 8 disengages from the clamping groove 201, and then rotate the connecting rod 7 to drive the clamping post 8 to rotate in the rotating groove 200 in the opposite direction of the installation direction until the clamping post 8 disengages from the rotating groove 200, and the camera 11 can be removed, which is simple and time-saving in operation.
