The following examples are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0024] like Figure 1-Figure 7As shown, the utility model provides a device for conveniently hanging a rotating camera in an underground mining field, including a guide rod 5; a hanger 1 is welded to the top of the guide rod 5, a telescopic control motor 2 is connected to the left side of the hanger 1 by bolts, an active bevel gear 4 is installed on the motor shaft of the telescopic control motor 2, the outer side of the active bevel gear 4 is meshedly connected to the driven bevel gear 3, the lower side of the driven bevel gear 3 is welded to a hanger 7, the lower side of the hanger 1 is provided with a through hole, and the top of the hanger 7 is rotatably connected in the through hole of the hanger 1; it also includes a telescopic rod 6, a camera shell 9 and a guide rod 14; a mounting box 8 is welded to the upper side of the camera shell 9, the upper side and lower side centers of the mounting box 8 are provided with through holes, the front side and rear side of the mounting box 8 are provided with through holes, and the front side and rear side of the mounting box 8 are provided with through holes. A bidirectional threaded rod 20 is rotatably connected in the through hole, a knob 11 is installed at the front end of the bidirectional threaded rod 20, a cleaning frame 12 is connected to the outer side of the camera housing 9 by bolts, a protective cover 10 is rotatably connected to the bottom end of the camera housing 9, a motor frame 19 is welded to the inner side of the camera housing 9, a cleaning motor 17 is connected to the upper side of the motor frame 19 by bolts, a driving gear 18 is installed on the motor shaft of the cleaning motor 17, a pan-tilt camera 16 is installed inside the camera housing 9, and a programmable controller 15 is connected to the upper side of the pan-tilt camera 16 by wires; the programmable controller 15 is connected to the telescopic control motor 2 by wires, and the programmable controller 15 is connected to the cleaning motor 17 by wires; the telescopic rod 6 is meshedly connected to the suspension rod 7; and a clamping block 13 is slidably connected to the outer side of the guide rod 14.

[0025] When the utility model is carrying out the hanging and installation work of the underground camera equipment, the hanger 1 is prefabricated on the top of the mine cave, and the telescopic control motor 2 drives the active bevel gear 4 to rotate. Since the active bevel gear 4 and the driven bevel gear 3 are meshed and connected with each other, the active bevel gear 4 drives the driven bevel gear 3 to change direction and rotate, and the driven bevel gear 3 drives the suspension rod 7 welded on the lower side to rotate. Since the outer side of the telescopic rod 6 is threadedly meshed and connected in the threaded through hole of the suspension rod 7, the suspension rod 7 drives the telescopic rod 6 to move vertically downward along the convex strip structure of the guide rod 5 during the rotation process until the ring plate at the bottom end of the telescopic rod 6 drops to a suitable installation height, and then the ring plate at the bottom end of the telescopic rod 6 is butt-connected and inserted into the through hole of the installation box 8, and the rubber gasket bonded on the lower side of the ring plate of the telescopic rod 6 is attached to the upper side of the camera housing 9. At this time, the knob 11 is manually twisted, and the knob 11 drives the bidirectional threaded rod 20 to rotate. Since the threaded through holes of the two sets of clamping blocks 13 are respectively meshed and connected to the forward threaded end and the reverse threaded end of the bidirectional threaded rod 20, the bidirectional threaded rod 2 0 drives the two groups of clamping blocks 13 to move forward and backward along the guide rod 14, and the clamping blocks 13 clamp the telescopic rod 6. At this time, the lower side of the clamping block 13 is attached to the upper side of the ring plate of the telescopic rod 6, so that the clamping block 13 locks the telescopic rod 6 in the installation box 8, and the camera housing 9 is installed at the bottom end of the telescopic rod 6. Then the telescopic control motor 2 drives the suspension rod 7 to reverse through the active bevel gear 4 and the driven bevel gear 3, and the telescopic rod 6 moves vertically upward along the convex strip structure of the guide rod 5 to return to its original position, completing the hanging of the underground camera equipment. During the installation work, when cleaning the camera screen, the programmable controller 15 controls the cleaning motor 17 to drive the driving gear 18 to rotate. Since the driving gear 18 and the internal tooth structure of the shield 10 are meshed with each other, the driving gear 18 drives the shield 10 to rotate at a high speed. During the rotation of the shield 10, the outer side of the shield 10 sweeps across the cleaning rack 12, and the cotton strips on the inner side of the curved plate of the cleaning rack 12 clean and wipe the coal ash attached to the outer surface of the shield 10, so that the camera screen of the pan-tilt camera 16 remains clean.

[0026] In the disclosed embodiment, the telescopic rod 6 is a cylindrical structure that passes through from top to bottom. A threaded structure is provided on the outer side of the telescopic rod 6 near the top, and two groups of groove structures symmetrically distributed on the inner side of the telescopic rod 6 cylindrical structure are provided. A ring plate is provided at the bottom end of the telescopic rod 6, and a rubber gasket is bonded to the lower side of the ring plate to ensure that the ring plate of the telescopic rod 6 is tightly fitted to the outer side of the through hole on the upper side of the camera shell 9, preventing coal mine dust from entering from the connection between the camera shell 9 and the telescopic rod 6, and providing airtight protection for the pan-tilt camera 16 inside the camera shell 9.

[0027] In the disclosed embodiment, the outer side surface of the guide rod 5 is provided with two groups of symmetrically distributed convex strip structures, and the convex strip structures of the guide rod 5 are respectively embedded in the groove structures of the telescopic rod 6, so that the guide rod 5 limits the rotation of the telescopic rod 6 to ensure the directional vertical sliding of the telescopic rod 6.

[0028] In the disclosed embodiment, a threaded through hole extending vertically is provided at the center position of the upper side surface of the suspension rod 7, and the inner core of the threaded structure on the outer side surface of the telescopic rod 6 is meshedly connected in the threaded through hole of the suspension rod 7. During the rotation of the suspension rod 7 in the through hole of the hanger 1, the suspension rod 7 uses the thread to drive the telescopic rod 6 to move vertically along the guide rod 5. During installation or disassembly, the telescopic rod 6 is extended to lower the height of the camera housing 9, which is convenient for hanging installation.

[0029] In the embodiment of the present disclosure, there are two groups of clamping blocks 13, and the clamping blocks 13 are symmetrically distributed front to back. The front side surface of each group of clamping blocks 13 is symmetrically provided with through holes and threaded through holes that penetrate front to back. The positive threaded end of the two-way threaded rod 20 is meshed and connected in the threaded through hole of the front side clamping block 13, and the reverse threaded end of the two-way threaded rod 20 is meshed and connected in the threaded through hole of the rear side clamping block 13. The guide rod 14 is inserted into the through holes of the two groups of clamping blocks 13. The two-way threaded rod 20 drives the two groups of clamping blocks 13 to move left and right along the guide rod 14 inside the installation box 8. The two groups of clamping blocks 13 clamp the outer side surface of the telescopic rod 6. At this time, the lower side surface of the clamping block 13 is attached to the side surface of the ring plate of the telescopic rod 6, so that the clamping block 13 clamps and locks the telescopic rod 6 inside the installation box 8, completing the hanging installation of the camera shell 9 at the bottom end of the telescopic rod 6, and the operation is convenient and quick.

[0030] In the disclosed embodiment, the cleaning rack 12 is an arc-shaped curved plate structure, and a cotton strip is adhered to the inner side of the arc-shaped curved plate structure of the cleaning rack 12 via Velcro. The cotton strip of the cleaning rack 12 fits tightly to the outer side of the protective cover 10 to wipe the protective cover 10.

[0031] In the disclosed embodiment, the shield 10 is a hemispherical shell structure made of transparent plastic material. A circle of internal tooth structure is provided on the inner side of the hemispherical shell of the shield 10 near the top. The driving gear 18 is meshed and connected to the inner tooth structure of the shield 10, so that the cleaning motor 17 drives the shield 10 to rotate at high speed through the driving gear 18, so that the outer side of the hemispherical shell of the shield 10 rubs against the cotton strips adhered to the cleaning rack 12, thereby erasing the coal mine dust attached to the outer side of the shield 10 and maintaining the clarity of the camera.

[0032] The installation, connection or setting methods of all the above components are common mechanical methods, such as welding, threaded connection, screw connection, etc., and the specific structures, models and coefficient indicators of all its components are its own technology, as long as it can achieve its beneficial effects, it can be implemented. The telescopic control motor 2, programmable controller 15, pan-tilt camera 16, and cleaning motor 17 used above are all common components on the market. When you buy them back and use them, you only need to connect them according to the instruction manual purchased together, so I will not repeat them here.
