Description

Technical Field

[0001] This utility model relates to the field of mining equipment technology, specifically an intrinsically safe spherical camera. Background Technology

[0002] Intrinsically safe dome cameras for mining are safety monitoring devices specifically designed for coal mines and other mining environments. These cameras meet intrinsically safe standards, ensuring safe use in flammable and explosive mining environments. However, current intrinsically safe dome cameras for mining often experience surface dust accumulation due to the high levels of dust inside the mine. If this dust is not cleaned promptly, it will affect the camera's clarity. Currently, intrinsically safe dome cameras for mining lack external components for automatic surface cleaning, requiring manual operation. Therefore, we propose an intrinsically safe dome camera to address these issues. Utility Model Content

Detailed Implementation

[0022] 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.

[0023] Example

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, an intrinsically safe spherical camera according to one embodiment of this utility model includes a support base 1. A mounting plate 17 is fixed to one side wall of the support base 1. The side wall of the mounting plate 17 has four mounting holes, which facilitates the overall installation and fixing of the intrinsically safe spherical camera. A circular plate 3 is fixed to the bottom of the support base 1 by two bent rods 2. The spherical camera body 4 is fixed inside a through hole at the top of the circular plate 3. A transparent protective cover 5 for protecting the spherical camera body 4 is installed at the bottom of the circular plate 3. An annular seat 6 is provided above the circular plate 3. A drive mechanism 7 for driving the annular seat 6 to rotate is provided at the top of the support base 1. Two rotating rods 8 are rotatably connected to the annular seat 6 via bearings. Each rotating rod 8 has a transmission gear 9 fixed to its surface. Two miniature electric cylinders 10 are fixed to the top of the annular seat 6. Each miniature electric cylinder 10 has a connecting block 11 fixed to its ejector end. A rack 12 is fixed to the bottom of each connecting block 11. Four guide grooves 15 are provided on the annular seat 6. Guide blocks 16, matching the guide grooves 15, are fixed to the side walls of the two racks 12, providing guidance and support for the racks 12, thus ensuring greater stability during movement. Each rack 12 meshes with a corresponding transmission gear 9. A transparent protective cover 5 is fixed to the surface of each rotating rod 8. The hollow arc-shaped brush plate 13 is attached to the surface of the transparent protective cover 5. An air blowing assembly 14 is installed at the bottom of the support base 1. When using this intrinsically safe spherical camera, the transparent protective cover 5 further protects the spherical camera body 4. When cleaning the surface of the transparent protective cover 5 is required, the drive mechanism 7 can be activated to rotate the annular seat 6. The rotation of the annular seat 6 causes the hollow arc-shaped brush plate 13 to rotate on the surface of the transparent protective cover 5, thus cleaning the dust adhering to its surface. Simultaneously, the air blowing assembly 14 is activated. The air blown out will be sent to the surface of the transparent protective cover 5 through the hollow arc-shaped brush plate 13. This can prevent dust from remaining on the surface of the transparent protective cover 5 and also prevent dust from remaining on the hollow arc-shaped brush plate 13 during cleaning. After cleaning is completed, the top ends of the two waterproof, dustproof and explosion-proof miniature electric cylinders 10 can be activated to retract and drive the connecting block 11 to move. After the connecting block 11 moves, it will drive the rack 12 to move. After the rack 12 moves, it will drive the transmission gear 9 to rotate. At this time, the two hollow arc-shaped brush plates 13 can be rotated and folded upwards in opposite directions, so as to avoid obstructing the transparent protective cover 5 and affecting the normal use of the spherical camera body 4.

[0025] like Figure 1 , Figure 3 and Figure 5As shown, in some embodiments, the drive mechanism 7 includes a rotating shaft 701 rotatably connected to the top of the support base 1 via bearings. A drive gear 702 is fixed to the surface of the rotating shaft 701. A gear ring 704 is fixed to the top of the annular seat 6 via four connecting rods 703. The gear ring 704 meshes with the drive gear 702. An annular rail 705 is fixed to the surface of the support base 1. A rotating ring 706 adapted to the annular rail 705 is fixed to the top of the gear ring 704. In use, the rotating shaft 701 can be driven to rotate by starting a waterproof, dustproof, and explosion-proof motor. After the rotating shaft 701 rotates, it will drive the drive gear 702 to rotate. After the drive gear 702 rotates, it will drive the gear ring 704 to rotate. Finally, when the gear ring 704 rotates, it can drive the annular seat 6 to rotate via the connecting rods 703.

[0026] like Figure 2 and Figure 5 As shown, in some embodiments, the air blowing assembly 14 includes a miniature electric air pump 1401 fixed to the bottom of the support base 1. Two corrugated hoses 1402 are connected and fixed to the air outlet pipe of the miniature electric air pump 1401. The other ends of the corrugated hoses 1402 are respectively connected and fixed to the hollow arc-shaped brush plates 13. Air blowing holes 1403 are provided in an arc-shaped array on the hollow arc-shaped brush plates 13. When in use, when the hollow arc-shaped brush plates 13 are cleaning the surface of the transparent protective cover 5, the miniature electric air pump 1401 will also start. Then, the miniature electric air pump 1401 will send the air it blows through the corrugated hoses 1402 to the hollow arc-shaped brush plates 13 for blowing. At this time, the transparent protective cover 5 after being cleaned by the hollow arc-shaped brush plates 13 can be cleaned again to prevent dust from remaining on the surface of the transparent protective cover 5.

[0027] like Figure 4 As shown, in some embodiments, the bottom of the circular plate 3 is provided with internal threads, and the surface of the transparent protective cover 5 is provided with external threads, so that the transparent protective cover 5 can be easily disassembled and assembled with the circular plate 3, thereby facilitating the later maintenance of the spherical camera body 4 installed on the circular plate 3.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
