The cleaning method of the camera 100 according to the embodiment of the present invention is specifically described below in conjunction with the camera 100 according to the embodiment of the present invention. As shown in fig. 1 to 12, a camera 100 according to an embodiment of the present invention includes a body 1, a camera, a housing 2, and a cleaning assembly.

The camera and the housing 2 are arranged on the body 1, and the camera is positioned in the housing 2. Specifically, the housing 2 is made of a light-transmitting material, and at least a part of the outer surface of the housing 2 is spherical. The cover 2 is, for example, a hemispherical glass cover.

As shown in fig. 1 to 12, the cleaning assembly comprises cleaning members 4, a drive socket 5, a drive member 6, a nozzle 8 and a return member.

The body 1 comprises a mounting frame 3, i.e. the mounting frame 3 is a part of the body 1. Specifically, the mounting frame 3 is annular, and the mounting frame 3 is sleeved on the outer peripheral side of the housing 2.

The cleaning member 4 is located outside the casing 2, and the cleaning member 4 is movably arranged on (the mounting frame 3 of) the body 1 (the cleaning member 4 is movable relative to the casing 2) so that the cleaning member 4 has an initial position and a cleaning position, and the cleaning member 4 can clean the casing 2 when moving between the initial position and the cleaning position. Specifically, the cleaning member 4 is rotatably provided on (the mounting bracket 3 of) the body 1, and the cleaning member 4 is rotatable between an initial position and a cleaning position and contacts with the outer surface of the housing 2 during rotation to clean the housing 2. The cleaning elements 4 are shaped to fit the outer surface of the housing 2, so that the contact area of the cleaning elements 4 with the outer surface of the housing 2 is larger, in order to better clean the housing 2. For example, the contact portion of the cleaning member 4 with the outer surface of the housing 2 is arc-shaped, and the contact portion of the cleaning member 4 with the outer surface of the housing 2 is made of a rubber material.

As shown in fig. 3, 4, 5, 8, 11 and 12, the drive socket 5 has a drive chamber 7 and a first inlet 9 communicating with the drive chamber 7. The driver element 6 is movably arranged in the drive chamber 7 such that the driver element 6 has a first position and a second position, the first inlet 9 being adapted to be accessed by a medium for urging the driver element 6 to move from the first position to the second position. The driving member 6 is connected with the cleaning member 4, and the driving member 6 moves the cleaning member 4 from the initial position to the cleaning position in the process of moving from the first position to the second position. A medium (power source) with a certain pressure is introduced into the driving cavity 7 to drive the driving part 6 to move, so that the cleaning part 4 is driven to move from the initial position to the cleaning position, and the cleaning work is completed. In particular, when the driving member 6 is in the first position, the cleaning members 4 are in the initial position; when the drive member 6 is in the second position, the cleaning members 4 are in the cleaning position.

Optionally, the medium comprises a liquid, a gas. For example, the medium is water.

In step S1, after the feeding device stops feeding the medium into the driving cavity 7, the reset member drives the cleaning member 4 to move from the cleaning position to the initial position, and drives the driving member 6 to move from the second position to the first position.

As shown in fig. 1 to 12, a restoring member is connected to the body and the cleaning member 4, and the restoring member can drive the cleaning member 4 to move from the cleaning position to the initial position. Specifically, the reset piece is an elastic piece 14 and is arranged on the mounting frame 3 of the body 1, the elastic piece 14 can be elastically deformed, one end of the elastic piece 14 is connected with the mounting frame 3 of the body 1, and the other end of the elastic piece 14 is connected with the cleaning piece 4. When the cleaning piece 4 is driven to move from the initial position to the cleaning position in the process that the driving piece 6 moves from the first position to the second position, the elastic piece 14 is elastically deformed; when the medium stops being introduced, the cleaning member 4 is restored under the action of the elastic member 14 and drives the cleaning member 4 to move from the cleaning position to the initial position, so that the cleaning member 4 is reset and the driving member 6 is reset (the driving member 6 is driven to move from the second position to the first position). The elastic member 14 is, for example, a torsion spring.

In some embodiments, the drive seat 5 has a third inlet (not shown) in communication with the drive chamber 7, the third inlet being adapted to be accessed by a medium for urging the drive member 6 from the second position to the first position. The driving member 6 is connected with the cleaning member 4, and the driving member 6 moves from the second position to the first position to drive the cleaning member 4 to move from the cleaning position to the initial position. Specifically, the first inlet 9 and the third inlet are located on two sides of the driving member 6, the first inlet 9 is accessed to the medium pushing driving member 6 to move from the first position to the second position, and the third inlet is adapted to the medium pushing driving member 6 to move from the second position to the first position, so as to drive the cleaning member 4 to reciprocate between the cleaning position and the initial position.

In step S1, the medium is continuously fed into the drive chamber 7 by the supply device, so that the medium in the drive chamber 7 can enter the lance 8 and be ejected toward the housing 2. The impurities on the surface of the housing 2 can be washed clean by the medium sprayed to the housing 2.

As shown in fig. 1 to 12, the lance 8 has a second inlet and a plurality of second outlets 12, each second outlet 12 facing the housing 2. Specifically, the driving seat 5 and the nozzle 8 are arranged on (the mounting frame 3 of) the body 1, the nozzle 8 is annular, the nozzle 8 is annularly arranged outside the housing 2, and the plurality of second outlets 12 are circumferentially arranged on the nozzle 8 at intervals.

The drive socket 5 also has a first outlet 10 communicating with the drive chamber 7, the first outlet 10 communicating with the second inlet, the first outlet 10 communicating with the first inlet 9 when the driving member 6 is in the second position. The inlet of the nozzle 8 communicates with the drive chamber 7 and the outlet of the nozzle 8 faces the housing 2. In this way, the medium which has passed into the drive chamber 7 can be passed through the first outlet 10 into the lance 8 (inlet) and the housing 2 can be flushed through the plurality of second outlets 12 (outlet of the lance 8) in order to further clean the housing 2.

In some embodiments, in step S1, the time for the feeding device to feed the medium into the driving chamber 7 is greater than or equal to 10 seconds. This makes it possible to subject the housing 2 to the media rinsing for a longer time, so that cleaning of the housing 2 is facilitated. After cleaning, the cleaning elements 4 can be wiped against the housing 2 again during the resetting process, so that the cleaning elements 4 can clean water mist and dust from the housing 2 and thus better clean the housing 2.

In some embodiments, step S1 is performed a number of times greater than or equal to 2. This allows the cleaning means 4 to wipe the housing 2 several times and the medium to flush the housing 2 several times. So that the housing 2 can be cleaned more effectively. For example, the number of times step S1 is performed is 3 times each time the housing 2 is cleaned.

In some embodiments, the supply device is provided with a control valve, by means of which the flow and/or pressure of the medium introduced into the drive chamber 7 is controlled in step S1. In particular, the supply means comprise a supply duct communicating with the drive chamber 7, on which a control valve is provided. When the medium is introduced into the drive chamber 7, at least one of the flow rate and the pressure of the medium in the supply line is adjusted by adjusting the control valve, so that at least one of the flow rate and the pressure of the medium introduced into the drive chamber 7 can be adjusted, and the medium introduced into the drive chamber 7 can drive the driving member 6 to move, and the medium from the outlet of the nozzle 8 has sufficient pressure.

As shown in fig. 1 to 12, in some embodiments, the cleaning member 4 is provided with a rotating shaft 13, and the rotating shaft 13 is rotatably provided on (the mounting frame 3 of) the body 1. For example, there are two rotating shafts 13, two ends of the cleaning element 4 are connected to one rotating shaft 13, and the elastic element 14 is sleeved on at least one rotating shaft 13. The axial direction of the rotating shaft may be a front-rear direction as indicated by an arrow in fig. 1.

As shown in fig. 1 to 4, in the first embodiment, a part of the rotary shaft 13 protrudes into the drive chamber 7. In particular, a rotary shaft 13 is rotatably provided on (the mounting frame 3 of) the body 1 and a portion of the rotary shaft 13 extends into the drive chamber 7.

The driving part 6 is a blade, the blade is connected with the rotating shaft 13, the thickness direction of the blade is vertical to the axial direction of the rotating shaft 13, and the blade is rotatably arranged in the driving cavity 7. Therefore, the blade can rotate around the axis of the rotating shaft 13 and can (substantially) block the driving cavity 7, and the medium is easy to impact the blade and drive the blade to move from the first position to the second position when the medium is introduced into the driving cavity 7. For example, the thickness direction of the blade is perpendicular to the front-rear direction.

As shown in fig. 3, in some embodiments, the drive chamber 7 includes a first wall 17, a second wall, an arcuate face 18, and a flat face 19. The first wall surface 17 and the second wall surface are disposed opposite to each other in the axial direction of the rotating shaft 13, and both the first wall surface 17 and the second wall surface are connected to the arc surface 18 and the flat surface 19. The arc-shaped surface 18 and the plane 19 are oppositely arranged, and two ends of the extension direction of the arc-shaped surface 18 (arc-shaped) are respectively connected with two ends of the plane 19. During the rotation of the vane, the vane is slidably connected to the first wall surface 17, the second wall surface, the arc surface 18 and the plane 19, and the first inlet 9 and the first outlet 10 are respectively adjacent to two ends of the extension direction of the arc surface 18. Therefore, before the blade moves to the second position, the fluid medium is easy to drive the blade to rotate and is difficult to enter the first outlet 10; after the vane has moved to the second position, the fluid medium may pass into the first outlet 10.

As shown in FIG. 3, in some embodiments, the blade includes a first section 15 and a second section 16 that are connected. The rotating shaft 13 is arranged in the first section 15, the thickness of the first section 15 is larger than that of the second section 16, and the surface, far away from the second section 16, of the first section 15 is an arc surface suitable for being in sliding connection with the plane 19, so that the surface, far away from the second section 16, of the first section 15 is always in sliding connection with the plane 19 in the rotating process of the blade. Optionally, the face of the second segment 16 remote from the first segment 15 is a curved face adapted to slidingly engage the curved face 18.

In a second embodiment, as shown in fig. 5 to 8, the driving chamber 7 is a circular arc chamber, and the driving member 6 is a circular arc rod and is adapted to the shape of the driving chamber 7. In particular, the centre of the drive chamber 7 coincides with the centre of the driver 6, and the shape of the driver 6 is (substantially) identical to the shape of the drive chamber 7 in a cross-section perpendicular to the direction of extension of the circular arc of the driver 6 and the drive chamber 7. For example, in a cross section perpendicular to the direction of extension of the circular arc of the driver 6 and the drive chamber 7, the shape of the driver 6 and the shape of the drive chamber 7 are both quadrilateral.

The driver element 6 is slidably arranged in the drive chamber 7 in the (circular arc-shaped) extension direction of the drive chamber 7 and is rotatable relative to the drive socket 5 such that the driver element 6 has a first position and a second position, the first inlet 9 being adapted for letting in a medium for urging the driver element 6 to move from the first position to the second position. The driving member 6 is connected with the cleaning member 4, and the driving member 6 can drive the cleaning member 4 to move from the initial position to the cleaning position in the process of moving from the first position to the second position. The medium (power source) with certain pressure is introduced into the driving cavity 7 to drive the driving part 6 to slide, the driving part 6 slides along the arc-shaped extending direction of the driving cavity 7 to enable the driving part 6 to rotate relative to the driving seat 5, so that the cleaning part 4 is driven to move (rotate) to the cleaning position from the initial position, and the cleaning work is completed. In particular, when the driving member 6 is in the first position, the cleaning members 4 are in the initial position; 6 the cleaning members 4 are in the cleaning position when the drive member 6 is in the second position.

As shown in fig. 8, in some embodiments, the drive chamber 7 has a first end 20 and a second end 21 in the direction of extension thereof, the second end 21 being open, the first inlet 9 being adjacent the first end 20, the first outlet 10 being adjacent the second end 21, and one end of the drive member 6 extending out of the drive chamber 7 and being connected to the cleaning elements 4. Thus, the medium entering from the first inlet 9 and driving the chamber 7 can push the driving element 6 so that the first end 20 rotates in the direction of the second end 21 and during the rotation the cleaning elements 2 are rotated. When the drive member 6 reaches the second position, the medium in the drive chamber 7 can enter the nozzle 8 from the first outlet 10.

As shown in fig. 9 to 12, in the third embodiment, the driving cavity 7 is a cylindrical cavity, the axial direction of the driving cavity 7 is the same as the axial direction of the rotating shaft 13, the rotating shaft 13 is located at the axial position of the driving cavity 7, the vane includes a vane body and a connecting ring which are connected with each other, the connecting ring is sleeved on the rotating shaft 13, the vane body is slidably connected with the wall surface of the driving cavity 7, a partition 22 is arranged in the driving cavity 7, the partition 22 is connected with two axial wall surfaces of the driving cavity 7, the partition 22 is slidably connected with the connecting ring at a first radial end of the driving cavity 7, and the partition 22 is connected with the side wall of the driving cavity at a second radial end of the driving cavity 7. Specifically, the drive chamber 7 includes two circular wall surfaces axially opposite to each other in the drive chamber 7 and an annular side wall connected to the two circular wall surfaces, the partition 22 is connected to the two circular wall surfaces respectively at both sides of the drive chamber 7 in the axial direction, the partition 22 is connected to the annular side wall at a second end of the drive chamber 7 in the radial direction, and the partition 22 is slidably connected to the circumferential side of the connection ring at a first end of the drive chamber 7 in the radial direction. Thus, when the driving member 6 (vane) rotates, the vane body cooperates with the partition 22 to divide the driving chamber 7 into two chambers, and when the vane body is not rotated to the second position, the first inlet 9 and the first outlet 10 are separated by the vane body and the partition 22. When the vane body is rotated to the second position, the vane body may contact the partition 22, at which point the first inlet 9 is in communication with the first outlet 10.

In some embodiments, a baffle 23 is provided in the drive chamber 7, the baffle 23 being located axially of the drive chamber 7 between the first inlet 9 and the driver 6. For example, the divider 22 includes two divider plates that are angled and spaced at increasing distances away from the connector ring. The baffle plate 23 is a rubber baffle plate, and a baffle plate 23 adjacent to the first inlet 9 is arranged in the driving cavity 7 so as to block the blade body located at the first position and prevent the blade located at the first position from blocking the first inlet 9.

For example, a spray device is used as a water supply device, and a spray pipe communicating with the drive chamber 7 is provided in the spray device so as to introduce high-pressure water into the drive chamber 7.

In some embodiments, the medium is a cleaning fluid. The underground coal dust is oily or alkaline, the adhesion force on the housing 2 is strong, and when the camera 100 comprises the spray pipe 8, the cleaning liquid is used as a medium to clean the coal dust on the housing 2 conveniently.

In some embodiments, the medium comprises a liquid medium and a gaseous medium. Step S1 includes S11 and S12.

In step S11, a liquid medium is introduced into the drive chamber 7 by the supply device.

In step S12, a gaseous medium is introduced into the drive chamber 7 by the supply device.

Wherein, step S11 and step S12 are not in sequence. That is, the supply device may introduce the liquid medium into the driving chamber 7 and then introduce the gaseous medium, or introduce the gaseous medium first and then introduce the liquid medium. For example, the supply device comprises a liquid medium supply device and a gaseous medium supply device, and the liquid medium supply device and the gaseous medium supply device are both communicated with the driving cavity 7 so as to introduce gaseous medium or liquid medium into the driving cavity 7.
