Description

Technical Field

[0001] This application relates to the technical field of camera protection and cleaning, and particularly to a dual-camera protection device with a wiper under harsh working conditions. Background Art

[0002] Photographic equipment under harsh working conditions faces numerous challenges. Especially in the high-dust environment in mining-related processing workshops, traditional shooting equipment often has difficulty ensuring the shooting effect. To solve this problem, a number of dual-camera protection devices with wiper functions have emerged on the market. These devices ensure that the camera continues to maintain a clear view of the camera lens under harsh working conditions through the wiper set at the camera lens protection cover, ensuring that the shooting quality is not affected.

[0003] However, most of the dual-camera protection devices in traditional technologies are fixed through a multi-gear-group composed multi-angle cloud platform bracket to achieve multi-angle shooting and monitoring of the site. Under the harsh working conditions in the mining industry, it is difficult to ensure the stability of the equipment by adjusting the angle through the gear group, and it is difficult to maintain and the cost is relatively high. Summary of the Invention

[0004] Based on this, in view of the above technical problems, it is necessary to provide a dual-camera protection device with a wiper under harsh working conditions that has high stability, low maintenance cost, and can work stably in the high-dust environment of harsh working conditions.

[0005] This application provides a dual-camera protection device with a wiper under harsh working conditions, including a dual-camera cover, a first support frame, a second support frame, a transparent protective lens, a dual-camera assembly, and two electric control cleaning wipers, wherein:

It is convenient to install and easy to maintain. Compared with the traditional gear-structured cloud platform, due to its higher practical use value, and under the condition of the tremor of the support beam frame in harsh working conditions, it can effectively prevent the dual-camera cover from rotating excessively and prevent the dual-camera from getting out of the shooting or monitoring field of view; buckle the C-shaped clamp body on the beam frame with the open end facing downwards, so that the closed end of the C-shaped clamp body and the end close to the second U-shaped frame body are closely attached to the beam frame, and rotate the bolt to adjust the position of the chuck, so that the chuck and the end of the C-shaped clamp body close to the second U-shaped frame body clamp the beam frame tightly. A spherical joint is provided between the bolt and the chuck, which can cope with the foreign objects and protrusions remaining on the beam frame; the circuit board is used to control the wiper motor to drive the wiper to perform a reciprocating cleaning operation of 180 degrees on the transparent protective mirror, so as to ensure that the transparent protective mirrors in front of the two lenses of the dual-camera are kept clean. Since the transparent protective mirror is easily covered by stubborn dirt in the harsh high-dust working environment, using the dual-camera can greatly ensure the smooth completion of the shooting operation, and the transparent protective mirror is replaceable, reducing the maintenance probability and maintenance cost.

The three sixth through-holes 205 are distributed in an inverted triangle. Referring to Figure 6 , the C-shaped through-groove 303 is connected to the lowermost sixth through-hole 205 through the fourth bolt gasket assembly 304 to play a limiting role. One of the sixth through-holes 205 on both sides of the fifth through-hole 204 is connected to the C-shaped through-groove 303 through the fourth bolt gasket assembly 304 to play a role in restricting the rotation angle between the first U-shaped frame body 201 and the second U-shaped frame body 301. The third bolt gasket assembly 305 plays a role in enabling the two ends of the first U-shaped frame body 201 and the second U-shaped frame body 301 to be rotatably connected.

[0042] Further, as Figure 1 , Figure 2 , Figure 6 shown, a C-shaped clamp 4 is detachably installed on the second rotating U-shaped frame 3.

[0043] With this structure, referring to Figure 1 , when it is necessary to fix the entire device on the high beam in the workshop, buckle the C-shaped clamp body 401 on the beam with the open end facing downwards, so that the closed end of the C-shaped clamp body 401 and the end close to the second U-shaped frame body 301 are close to the beam. Rotate the bolt 501 to adjust the position of the chuck 502, so that the chuck 502 and the end of the C-shaped clamp body 401 close to the second U-shaped frame body 301 clamp the beam. A spherical joint 503 is provided between the bolt 501 and the chuck 502 to deal with foreign objects and protrusions remaining on the beam.

[0044] In an exemplary embodiment, when installing the C-shaped clamp 4, buckle the C-shaped clamp body 401 on the beam with the open end facing downwards, so that the closed end of the C-shaped clamp body 401 and the end close to the second U-shaped frame body 301 are close to the beam. Rotate the bolt 501 to adjust the position of the chuck 502, so that the chuck 502 and the end of the C-shaped clamp body 401 close to the second U-shaped frame body 301 clamp the beam. A spherical joint 503 is provided between the bolt 501 and the chuck 502 to deal with foreign objects and protrusions remaining on the beam.

[0045] In an exemplary embodiment, when installing the first rotating U-shaped frame 2 and the second rotating U-shaped frame 3, referring to Figure 1 , due to the special working condition environment, the beam may vibrate. To prevent the double camera cover 1 from rotating excessively clockwise along the axis of the third bolt gasket assembly 305, the fourth bolt gasket assembly 304 is installed between the upper sixth through hole 205 and the C-shaped through groove 303 to prevent excessive rotation.

[0046] In an exemplary embodiment, when installing the first U-shaped frame body 201 and the cover body 101, according to the required adjusted angle, rotate the angle of the cover body 101 through the first bolt gasket assembly 203. After rotation, through the second bolt gasket assembly 207, one or two of the communicating fourth through holes 206 and the second through hole 103 are fixed and limited, thus completing the angle adjustment.

[0047] Embodiment 4: During operation in a harsh working condition environment, if the transparent protective mirror 6 is blocked by dust, mud, oil stains, etc., the remote control circuit board 702 is used to control the wiper motor 902 to drive the wiper 901 to clean the transparent protective mirror 6 in front of the lenses at both ends of the double camera assembly 8. The circuit board 702 adopts remote control technology.

[0048] For those of ordinary skill in the art, without departing from the concept of this application, several deformations and improvements can still be made, and these all belong to the protection scope of this application. Therefore, the protection scope of this application should be subject to the appended claims.
