Description

Technical Field

[0001] The present application relates to the technical field of mining cameras, and in particular to an automatic dust removal camera for mining. Background Art

[0002] Mining cameras are installed in mines to transmit the mining conditions underground to the surface, providing strong support for mining work in mines. Due to the harsh environment underground, the camera lenses of mining cameras need to be cleaned regularly.

[0003] Existing mining cameras are usually equipped with a wiper cleaning device, which can clean the dust attached to the camera lens by swinging the wiper to keep the mining camera clear. In order to reduce the damage rate, the camera lens is usually built into the housing of the mining camera, which will cause the camera lens to be close to the edge of the housing of the mining camera, which is easy to form a cleaning dead angle that is difficult for the wiper to clean, and thus easily cause the edge of the mining camera to be blurred. Summary of the invention

[0004] In order to facilitate the cleaning of the blind spots at the edge of the camera lens so that the edge of the captured image can be clear, the present application provides an automatic dust removal camera for mining.

A purge hole is provided on the purge block, and the purge hole is used to connect the inside of the box body of the purge air box and the cleaning area. One end of the purge hole near the cleaning area is used to face the edge area of ​​the camera lens;

[0009] The position adjustment part is arranged on the rotating gas shell and is used to adjust the position of the purge block on the purge gas box by means of gas pressure;

[0010] The air supply part is connected to the purge air box and the position adjustment part, and is used for supplying air to the position adjustment part and the purge air box in sequence.

[0011] By adopting the above technical scheme, the purge block is first slid into the purge air box, so that it is not easy to block the edge position of the shooting picture when it is not cleaned; when cleaning, the air supply part supplies the airflow to the adjustment part and the purge air box in sequence, and the adjustment part drives the purge block to slide out of the purge air box under the action of the air pressure of the airflow, so that the purge hole is toward the edge position of the camera lens, and then the airflow enters the purge air box, and the airflow blows from the purge hole to the edge position of the camera lens. On the one hand, the airflow drives the purge block and the rotating air shell to rotate with the camera lens as the support point, and on the other hand, the airflow sweeps the edge position of the camera lens during the rotation to clean the edge position of the camera lens, thereby making it easy to clean the blind spot position of the edge of the camera lens.

[0012] Optionally, the positioning part includes a positioning air shell and a positioning telescopic rod, the other part of the rotating air shell is arranged away from the camera body, the positioning air shell is fixed on the supporting air shell, and is rotatably connected with the rotating air shell, and a closed space is formed between the positioning air shell and the rotating air shell;

[0013] At least one positioning telescopic rod is provided, and corresponds to the purge block one by one. The positioning telescopic rod is located in the positioning gas shell and is fixed on the side of the purge gas box away from the camera body. The movable end of the positioning telescopic rod slides into the purge gas box. The purge block is inclined at one end located in the purge gas box. The movable end of the positioning telescopic rod is slidably set on the inclined surface of the purge block. When the positioning telescopic rod is extended, the purge block partially slides out of the box body of the purge gas box. The rodless cavity of the positioning telescopic rod is connected to the positioning gas shell, and the rod cavity is connected to the purge gas box. The air supply part is used to supply air to the positioning gas shell.

[0014] By adopting the above technical solution, the air flow flows into the rodless cavity of the positioning telescopic rod through the positioning air shell to drive the positioning telescopic rod to extend, and the positioning telescopic rod is supplied with air through the positioning air shell, so that the positioning telescopic rod can be in a pressure-maintaining state when it rotates with the purge block; when the positioning telescopic rod is extended, the inclined surface of the purge block can drive the purge block to partially slide out of the purge air shell, so that the purge hole on the purge block can be oriented toward the edge position of the camera lens.

[0016] By adopting the above technical solution, the air pump supplies air to the air inlet pipe, and the air inlet pipe directs the air flow to the positioning air pipe and the purge air pipe. Since a one-way air valve is provided between the positioning air pipe and the purge air pipe, the air flow is first directed to the positioning air pipe. When the air pressure in the positioning air shell reaches a preset value, that is, the positioning telescopic rod drives the purge block to partially slide out of the purge air box, the air flow is then directed to the purge air pipe through the one-way air valve to supply air to the purge air box, thereby realizing the sequential air supply to the positioning air shell and the purge air box.

[0017] Optionally, a positioning spring for driving the positioning telescopic rod to contract is arranged in the rod cavity of the positioning telescopic rod, and a gap is left between the valve core of the one-way air valve and the valve body under normal conditions.

[0018] By adopting the above technical solution, when the air supply part stops supplying air to the positioning air shell, the positioning spring can drive the positioning telescopic rod to retract through elastic force. Since there is a gap between the valve core and the valve body of the one-way air valve, the air in the rodless cavity of the positioning telescopic rod can be discharged under the drive of the positioning spring, so that the positioning telescopic rod can drive the purge block to automatically slide into the purge air box when cleaning stops.

[0020] The first switching part and the second switching part are both connected to the fill light cleaning part. The first switching part is used to stop the movement of the fill light cleaning part when the mirror cleaning part is facing the camera lens, and the second switching part is used to resume the movement of the fill light cleaning part after the mirror cleaning part cleans the camera lens.

[0021] By adopting the above technical scheme, the fill light cleaning unit can clean the surface of the camera body and the fill light lens during the movement, thereby improving the fill light effect of the camera body; the fill light cleaning unit can drive the mirror cleaning unit to move to the camera lens, and under the action of the first switching unit, the mirror cleaning unit can stay at the camera lens to clean the camera lens, so that the camera lens as a whole can be cleaned without dead angles; after the mirror cleaning unit cleans the camera lens, under the action of the second switching unit, the fill light cleaning unit can continue to drive the mirror cleaning unit to move, so that under the joint action of the first switching unit and the second switching unit, both the camera lens and the fill light lens can be cleaned.

[0022] Optionally, the fill light cleaning unit includes a cleaning brush rod and a reciprocating screw, the cleaning brush rod is slidably arranged on the camera body, the reciprocating screw is rotatably connected to the camera body, and a thread is passed through one end of the cleaning brush rod.

[0023] By adopting the above technical solution, the reciprocating screw is rotated so that the cleaning brush rod can reciprocate on the camera body. The cleaning brush rod realizes reciprocating cleaning of the camera body surface and the fill light lens during the reciprocating movement.

[0024] Optionally, the fill light cleaning unit also includes an impeller and an air duct, the impeller is coaxially fixed to one end of the reciprocating screw, one end of the air duct is connected to the purge air box, and the other end is directed to the blade on one side of the impeller axis direction.

[0025] By adopting the above technical solution, the air flow in the purge air box can be blown onto the blades on one side of the impeller axis direction through the air guide pipe to drive the impeller to rotate. The impeller drives the reciprocating screw to rotate, so that the driving force of the cleaning brush rod can be assisted by the air flow in the purge air box, thereby reducing the driving source and reducing energy consumption.

[0026] Optionally, the mirror cleaning part includes a cleaning brush disc and a magnetic ring. The cleaning brush disc is rotatably connected to a cleaning brush rod on a side close to the camera body. The magnetic ring is coaxially fixed on the cleaning brush disc. The rod body of the positioning telescopic rod is made of ferromagnetic material. When the cleaning brush disc is facing the camera lens, the positioning telescopic rod is facing the magnetic ring and is magnetically connected to the magnetic ring.

[0027] By adopting the above technical solution, when the cleaning brush disc is facing the camera lens, the positioning telescopic rod can be magnetically connected to the magnetic ring. When the purge block drives the positioning telescopic rod to rotate, the positioning telescopic rod can drive the cleaning brush disc to rotate through the magnetic ring, so that the cleaning brush disc can clean the camera lens in a rotating state, thereby improving the cleaning effect of the camera lens.

[0028] Optionally, the first switching part includes a first rack, a first gear and a ball valve, two first racks are provided and are symmetrically connected to the cleaning brush rod, the first rack is arranged along the sliding direction of the cleaning brush rod, two first gears are provided and correspond one-to-one to the first racks, the first gear is used to mesh with the first rack, the ball valve is arranged on the air duct, and the ball in the ball valve is coaxially fixed to the two first gears.

[0029] By adopting the above technical solution, the cleaning brush rod can drive the first rack to move when sliding. When the first rack is meshed with the first gear, the first rack can drive the first gear to rotate, and the torsion spring accumulates elastic force. The first gear drives the ball of the ball valve to rotate, so that the ball valve closes the air duct, thereby making the cleaning brush rod lose driving force, so that the cleaning brush disc can stay at the camera lens, so that the cleaning brush disc can stop moving when facing the camera lens.

[0030] Optionally, the second switching part includes a second gear, a second rack, a switching spring and a torsion spring. The second gear is coaxially fixedly connected to the cleaning brush plate. Two second racks are provided and are symmetrically arranged on both sides of the second gear. The two second racks are meshed with the second gear and are respectively fixedly connected to the first rack one by one. The second rack is slidably arranged on the cleaning brush rod. The sliding directions of the two second racks are directions of approaching or moving away from each other.

When the second gear rotates more than three circles, the first rack is disengaged from the first gear. Two torsion springs are provided and are respectively arranged between the two first gears and the camera body. The torsion spring is used to drive the ball of the ball valve to reset.

[0031] By adopting the above technical solution, the torsion spring accumulates elastic force when the first rack drives the first gear to rotate, and the cleaning brush plate can drive the second gear to rotate as the positioning telescopic rod rotates, and the second gear drives the two second racks to slide in the direction away from each other, and makes the switching spring accumulate elastic force, and the second rack drives the first rack to slide, and when the second gear rotates more than three circles, the second rack can drive the first rack to disengage from the first gear, so that the first gear can drive the ball of the ball valve to reset under the elastic force of the torsion spring, so as to restore the conductive state of the air duct, so that the cleaning brush rod can automatically slide again after stopping, and the switching spring can drive the two second racks to reset through elastic force after the first rack and the first gear are disengaged.
