Description

Technical Field

[0001] The present application relates to the technical field of mine cameras, and in particular to a mine intrinsically safe environment perception camera. Background Art

[0002] In order to comprehensively monitor potential safety hazards in the mine, gas sensors, carbon monoxide sensors, oxygen sensors, and temperature sensors are integrated on the mine camera, enabling the mine camera to perceive and monitor the mine environment from multiple angles, so that the mine camera can be applied in the coal mining seam to comprehensively perceive potential safety hazards that may occur during the coal mining process.

[0003] Existing mine cameras usually have a cleaning mechanism. For example, a mine intrinsically safe camera disclosed in Chinese Patent with publication number CN221408963U, and a mine dust removal camera disclosed in Chinese Patent with publication number CN222423814U. The cleaning mechanism can scrub and clean the lens glass of the camera to prevent dust from blocking the lens glass of the camera.

[0004] The camera installed in the coal mining seam is prone to adhering to oil stains and dust stains. Since it is difficult to clean the oil stains and dust stains, it takes a long time to clean the oil stains and dust stains on the lens glass through the cleaning mechanism, which is likely to delay the shooting operation of the camera. Summary of the Invention

When the scrubbing electric cylinder contracts, the two scrubbing frames swing in the direction close to each other, and the scrubbing frame can fit on the lens glass.

[0011] Optionally, the scraping and washing part includes scraping bars, lead screws, guide rods and scraping and washing motors. There are two scraping bars, lead screws, guide rods and scraping and washing motors, which are symmetrically arranged and correspond to the scrubbing frames one by one.

Detailed implementation mode

[0019] The following will further elaborate on this application Figures 1 - 9 in conjunction with the attached drawings.

[0020] An intrinsically safe mine environmental perception camera is disclosed in an embodiment of this application. Refer to Figure 1 , Figure 2 and Figure 3 , an intrinsically safe mine environmental perception camera includes an explosion-proof shell 1, a partition shell 2, a lens glass 3, a cleaning component 4, a rotating component 5 and a sealing component 6.

[0021] Refer to Figure 1 and Figure 2 , a shooting hole 11 is opened on the explosion-proof shell 1. The partition shell 2 is fixedly arranged inside the explosion-proof shell 1 and is close to the shooting hole 11. The partition shell 2 divides the explosion-proof shell 1 into two spaces. The space close to the shooting hole 11 is the cleaning chamber 21, and the space far from the shooting hole 11 is the camera chamber 22. A camera main body 23 is arranged in the camera chamber 22, and the camera main body 23 is used for shooting monitoring pictures.

[0022] Refer to Figure 2 , the lens glass 3 is in the shape of a circular plate and is rotatably arranged at the rotation hole 24 opened on the partition shell 2. Half of the lens glass 3 faces the lens of the camera main body 23, and the other half is suspended in the cleaning chamber 21. The half of the lens glass 3 suspended in the cleaning chamber 21 is the cleaning part of the lens glass 3.

[0023] Refer to Figure 3 and Figure 4, in order to enhance the sealing performance between the lens glass 3 and the partition housing 2, the side of the lens glass 3 is located in the sealing groove 25 opened on the hole wall of the rotating hole 24. A sealing strip 26 is fixedly arranged in the sealing groove 25, and the sealing strip 26 is pressed against the side of the lens glass 3.

[0024] Refer to Figure 2 and Figure 3 , the cleaning assembly 4 is arranged in the cleaning chamber 21, and the cleaning assembly 4 includes a liquid spraying part 41, a scrubbing part 42 and a scraping part 43.

[0025] The liquid spraying part 41 is connected to the explosion-proof housing 1 and is used for spraying cleaning agent on both sides of the cleaning part of the lens glass 3. The scrubbing part 42 is arranged on the explosion-proof housing 1 and is used for scrubbing both sides of the cleaning part of the lens glass 3 with the help of the cleaning agent. The scraping part 43 is arranged on the scrubbing part 42 and is used for scraping the cleaning agent and oil stains on both sides of the cleaning part of the lens glass 3. When the scraping part 43 is scraping, the scrubbing part 42 can make room for the movement of the scraping part 43.

[0026] Refer to Figure 3 , the rotating assembly 5 is respectively connected to the partition housing 2 and the lens glass 3, and the rotating assembly 5 is used for driving the lens glass 3 to rotate 180 degrees.

[0027] Refer to Figure 2 , the sealing assembly 6 includes a corrugated sealing cylinder 61 and a sealing part 62.

[0028] Refer to Figure 1 and Figure 2 , the corrugated sealing cylinder 61 is arranged at the shooting hole 11 and is fixedly connected to the explosion-proof housing 1. The sealing part 62 is connected to the corrugated sealing cylinder 61. When the lens glass 3 is stationary, the sealing part 62 is used to make the corrugated sealing cylinder 61 press tightly against the lens glass 3. When the lens glass 3 rotates, the sealing part 62 is used to make the corrugated sealing cylinder 61 release the pressing force on the lens glass 3.

[0029] During use, after oil stains adhere to the area of the lens glass 3 facing the corrugated sealing cylinder 61, the sealing part 62 releases the pressing force between the corrugated sealing cylinder 61 and the lens glass 3, so that the lens glass 3 is in a rotatable state. At this time, the corrugated sealing cylinder 61 is in a fitting state with the lens glass 3. Then, the rotating assembly 5 drives the lens glass 3 to rotate, so that the lens glass 3 rotates 180 degrees, so that the area of the lens glass 3 with adhered oil stains can be located in the cleaning chamber 21. After the lens glass 3 rotates 180 degrees, the sealing part 62 makes the corrugated sealing cylinder 61 press tightly against the lens glass 3 again to re-seal the area between the shooting hole 11 and the lens glass 3.

[0030] The liquid spraying part 41 sprays the cleaning agent onto both sides of the cleaning part of the lens glass 3. The scrubbing part 42 scrubs both sides of the cleaning part of the lens glass 3. With the assistance of the cleaning agent, the oil stains and dust on the lens glass 3 will gradually separate from the lens glass 3. Then, the scraping part 43 scrapes both sides of the cleaning part of the lens glass 3, so that the cleaning agent and the oil stains and dust on the lens glass 3 can be scraped off the lens glass 3. And when the scraping part 43 scrapes the lens glass 3, the scrubbing part 42 can make room for the movement of the scraping part 43. On the one hand, it makes it difficult for the scrubbing part 42 to stick the cleaning agent and oil stains and dust on itself to the lens glass 3. On the other hand, it makes it difficult for the scraping process of the scraping part 43 to be hindered.

[0031] Based on the above analysis, after oil stains and dust adhere to the lens glass 3 facing the camera body 23, the lens glass 3 can be rotated so that the part of the lens glass 3 with oil stains and dust can be rotated to the cleaning assembly 4, and the clean part of the lens glass 3 can be rotated to the position facing the camera body 23, making it difficult for the cleaning of the lens glass 3 to interfere with the picture shooting of the camera body 23. Thus, during the long-term cleaning process of the lens glass 3, the camera body 23 can normally perform the shooting operation, and the cleaning of the oil stains and dust on the lens glass 3 is not likely to delay the shooting operation of the camera.

[0032] Specifically, referring to Figure 2 , the liquid spraying part 41 includes a liquid storage box 411, a spraying pump 412 and a spraying pipe 413.

[0033] There are two liquid storage boxes 411, spraying pumps 412 and spraying pipes 413, which are symmetrically arranged. The liquid storage box 411 is used to store the cleaning agent. The liquid storage box 411 is located on the side of the lens glass 3 and is fixedly connected to the explosion-proof shell 1. The spraying pumps 412 are in one-to-one communication with the liquid storage boxes 411. One end of the spraying pipe 413 is in one-to-one communication with the spraying pumps 412, and the other end is connected to two guiding spray pipes 414. The ends of the two guiding spray pipes 414 away from the spraying pipe 413 respectively face both sides of the cleaning part of the lens glass 3.

[0034] When cleaning is required, the two spraying pumps 412 act simultaneously. The spraying pumps 412 suck the cleaning agent in the liquid storage box 411 into the spraying pipe 413, and the cleaning agent is sprayed on the lens glass 3 from the guiding spray pipes 414, so that both sides of the cleaning part of the lens glass 3 can be sprayed with the cleaning agent to facilitate the cleaning of oil stains and dust.

[0035] Specifically, referring to Figure 3 , the scrubbing part 42 includes a scrubbing frame 421, a scrubbing motor 422 and a sponge scrub 423.

[0036] Referring to Figure 2 and Figure 3, there are two scrubbing frames 421, scrubbing motors 422, and sponge scrubbers 423 symmetrically arranged. The scrubbing frame 421 is in the shape of a rectangular frame, located on the side of the lens glass 3, and connected to the explosion-proof housing 1; the scrubbing motors 422 are connected to the scrubbing frames 421 one by one; the sponge scrubbers 423 are fixedly connected to the output shafts of the scrubbing motors 422 one by one, and the sponge scrubbers 423 are used to scrub the lens glass 3 after absorbing the cleaning agent.

[0037] Among them, referring to Figure 3 , in order to enable the sponge scrubber 423 to stably scrub the lens glass 3, a support plate 4223 is fixedly connected to the output shaft of the scrubbing motor 422, and the sponge scrubber 423 is fixedly connected to the support plate 4223.

[0038] After spraying the cleaning agent, the scrubbing motor 422 is actuated. The scrubbing motor 422 drives the sponge scrubber 423 to rotate. The sponge scrubber 423 absorbs the cleaning agent and continuously scrubs the lens glass 3 during rotation. After a period of time, the sponge scrubber 423 can remove the oil stains and dust on the lens glass 3 with the help of the cleaning agent, so that the oil stains and dust can be cleaned off.

[0039] Referring to Figure 3 and Figure 5 , in order to expand the cleaning range of the sponge scrubber 423, the scrubbing motor 422 is slidably connected with a rack 4221. The rack 4221 is connected to the scrubbing frame 421. A gear 4222 is fixedly connected to the output shaft of the scrubbing motor 422. The gear 4222 meshes with the rack 4221, and the scrubbing motor 422 can drive the gear 4222 to rotate forward and backward.

[0040] When the scrubbing motor 422 drives the sponge scrubber 423 to rotate, the scrubbing motor 422 synchronously drives the gear 4222 to rotate. Under the meshing drive of the gear 4222 and the rack 4221, the scrubbing motor 422 can slide relative to the rack 4221, so that the sponge scrubber 423 can move relative to the lens glass 3 during rotation. Since the scrubbing motor 422 can drive the gear 4222 to rotate forward and backward, the sponge scrubber 423 can move back and forth, thus expanding the cleaning range of the sponge scrubber 423 and enabling half of the lens glass 3 suspended in the cleaning chamber 21 to be cleaned.

[0041] Referring to Figure 3 and Figure 6 , in order to enable the liquid spraying part 41 to spray the cleaning agent evenly and comprehensively onto the lens glass 3, the scrubbing part 42 further includes a scrubbing electric cylinder 424, a scrubbing plate 425, and a scrubbing connecting rod 426.

[0042] Referring to Figure 2 and Figure 6, the scrubbing electric cylinder 424 is fixedly connected to the explosion-proof housing 1; the scrubbing plate 425 is fixedly connected to the movable end of the scrubbing electric cylinder 424; there are two scrubbing connecting rods 426 symmetrically arranged and corresponding to the scrubbing frames 421 one by one. The bottom end of the scrubbing frame 421 is hinged to the explosion-proof housing 1. One end of the scrubbing connecting rod 426 is fixedly connected to the scrubbing frame 421, and the other end is slidably arranged on the scrubbing plate 425; when the scrubbing electric cylinder 424 extends, the two scrubbing frames 421 swing in the direction away from each other, and when the scrubbing electric cylinder 424 contracts, the two scrubbing frames 421 swing in the direction close to each other, and the scrubbing frame 421 can fit on the lens glass 3.

[0043] Among them, referring to Figure 6 , a circular rod-shaped sliding rod 4261 is fixedly connected to the end of the scrubbing connecting rod 426. The sliding rod 4261 is slidably arranged in a sliding groove 4251 opened on the scrubbing plate 425. The sliding rod 4261 and the sliding groove 4251 form a sliding connection structure between the scrubbing connecting rod 426 and the scrubbing plate 425.

[0044] Before spraying the cleaning agent, extend the scrubbing electric cylinder 424. The scrubbing electric cylinder 424 drives the scrubbing plate 425 to move towards the lens glass 3. The scrubbing electric cylinder 424 can drive the sliding rod 4261 to slide in the sliding groove 4251. When the sliding rod 4261 slides, it can drive the scrubbing connecting rod 426 to swing, and the scrubbing connecting rod 426 can drive the scrubbing frame 421 to swing, so that the scrubbing frame 421 can turn away from the lens glass 3, making it difficult for the sponge scrubber 423 to block the spraying of the cleaning agent.

[0045] Specifically, referring to Figure 7 , the scraping part 43 includes a scraping strip 431, a lead screw 432, a guide rod 433 and a scraping motor 434.

[0046] There are two scraping strips 431, lead screws 432, guide rods 433 and scraping motors 434 symmetrically arranged and corresponding to the scrubbing frames 421 one by one. The scraping strip 431 is arranged in the scrubbing frame 421 and is used to abut against the lens glass 3. Sliding blocks 4311 are fixedly connected to both ends of the scraping strip 431. The sliding blocks 4311 are slidably arranged in sliding grooves 4211 opened on the inner side wall of the scrubbing frame 421; the lead screw 432 is threadedly penetrated through one of the sliding blocks 4311 and is rotatably connected to the scrubbing frame 421; the guide rod 433 is slidably penetrated through the other sliding block 4311 and is fixedly connected to the scrubbing frame 421; the scraping motor 434 is located at one end of the lead screw 432. The scraping motor 434 is fixedly connected to the scrubbing frame 421, and the output shaft of the scraping motor 434 is fixedly connected to the lead screw 432.

[0047] After the scrubbing is completed, the scraping motor 434 is actuated. The scraping motor 434 drives the lead screw 432 to rotate, and the lead screw 432 drives the slider 4311 to slide. The slider 4311 drives the squeegee 431 and another slider 4311 to slide. During the sliding process, the squeegee 431 can scrape off the cleaning agent and oil stains on the lens glass 3 together, so that the lens glass 3 can be cleaned thoroughly.

[0048] Referring to Figure 3 , Figure 7 and Figure 8 , in order to enable the sponge scrubber 423 to make room for movement when the squeegee 431 scrapes the lens glass 3, both ends of the rack 4221 are fixedly connected with slide rods 427, and the middle of the slide rod 427 is connected to the end of the rack 4221. The slide rods 427 correspond to the sliders 4311 one by one. The slide rods 427 are slidably arranged on the scrubbing frame 421 in the direction of approaching or departing from the lens glass 3. A scrubbing spring 428 is fixedly arranged between the slide rods 427 and the scrubbing frame 421. The scrubbing spring 428 is used to urge the sponge scrubber 423 to abut against the lens glass 3. A push rod inclined surface 4312 is arranged on the slider 4311. When the slider 4311 slides, the slider 4311 can push the slide rod 427 away from the lens glass 3 through the push rod inclined surface 4312, so that the sponge scrubber 423 can make room for the movement of the squeegee 431.

[0049] When the squeegee 431 is scraping, the push rod inclined surface 4312 on the slider 4311 can push the slide rod 427 to slide in the direction away from the lens glass 3, and the slide rod 427 can drive the sponge scrubber 423 to move in the direction away from the lens glass 3, so that the sponge scrubber 423 can make room for the movement of the squeegee 431, and it also makes it difficult for the cleaning agent and oil stains on the sponge scrubber 423 to stick to the lens glass 3 when the squeegee 431 scrapes the lens glass 3; after the squeegee 431 is reset, the slide rod 427 can make the sponge scrubber 423 reset under the elastic force of the scrubbing spring 428.

[0050] Specifically, referring to Figure 9 , the rotating assembly 5 includes a self-locking motor 51. The self-locking motor 51 is fixedly connected to the partition shell 2, and the output shaft of the self-locking motor 51 is connected to the lens glass 3.

[0051] By driving the lens glass 3 to rotate through the self-locking motor 51, the rotation angle of the lens glass 3 can be stabilized, so that the area of the lens glass 3 adhering to oil stains can be stably located within the scrubbing area of the scrubbing part 42.

[0052] Referring to Figure 2 and Figure 9 , in order to enable the two positions of the lens glass 3 facing the camera body 23 to be adjusted, the rotating assembly 5 further includes a fixing bolt 52 and a connecting pipe 53.

[0053] Referring toFigure 1 and Figure 9 , the connecting pipe 53 is fixedly connected to the output shaft of the self-locking motor 51. The fixing bolt 52 is threadedly inserted into the connecting pipe 53, and the cylindrical sleeve pair is connected to the explosion-proof shell 1. The bolt head of the fixing bolt 52 is exposed outside the explosion-proof shell 1. A first clamping piece 54 is fixedly connected to the fixing bolt 52, and a second clamping piece 55 is fixedly connected to the connecting pipe 53. When the fixing bolt 52 is screwed into the connecting pipe 53, the first clamping piece 54 and the second clamping piece 55 can clamp the lens glass 3.

[0054] After the lens glass 3 has been used for a long time, turn the fixing bolt 52 to release the clamping force of the first clamping piece 54 and the second clamping piece 55 on the lens glass 3, so that the lens glass 3 can rotate relative to the connecting pipe 53. Then rotate the lens glass 3 to change the part of the lens glass 3 that has been facing the corrugated sealing cylinder 61 for a long time, so that the part of the lens glass 3 that has not faced the corrugated sealing cylinder 61 before faces the corrugated sealing cylinder 61, so that the part of the lens glass 3 facing the corrugated sealing cylinder 61 can be renewed.

[0055] Specifically, referring to Figure 3 , the sealing part 62 includes a sealing electric cylinder 621, a sealing box 622, a piston 623 and an air pipe 624.

[0056] Referring to Figure 2 and Figure 3 , the barrel wall of the corrugated sealing cylinder 61 is provided with a hollow. The sealing electric cylinder 621 and the sealing box 622 are both fixedly connected to the explosion-proof shell 1. The piston 623 is fixedly connected to the movable end of the sealing electric cylinder 621 and is slidably arranged in the sealing box 622 in a sealed manner. One end of the sealing box 622 close to the sealing electric cylinder 621 is open. The other end of the sealing box 622 is communicated with one end of the air pipe 624, and the other end of the air pipe 624 is communicated with the hollow barrel wall of the corrugated sealing cylinder 61. The air pipe 624 allows air to flow between the sealing box 622 and the corrugated sealing cylinder 61.

[0057] When it is necessary to release the pressing state between the corrugated sealing cylinder 61 and the lens glass 3, the sealing electric cylinder 621 is contracted. The sealing electric cylinder 621 drives the piston 623 to slide. The piston 623 sucks the air in the corrugated sealing cylinder 61 into the sealing box 622 through the air pipe 624, so that the air pressure in the hollow barrel wall of the corrugated sealing cylinder 61 is reduced, so that the corrugated sealing cylinder 61 can only fit on the lens glass 3; when it is necessary to press the corrugated sealing cylinder 61 against the lens glass 3, the sealing electric cylinder 621 is extended. The sealing electric cylinder 621 drives the piston 623 to slide in the reverse direction. The piston 623 pushes the air in the sealing box 622 into the hollow barrel wall of the corrugated sealing cylinder 61 to increase the air pressure in the hollow barrel wall of the corrugated sealing cylinder 61, so that the corrugated sealing cylinder 61 can press against the lens glass 3.

[0058] The implementation principle of a mine intrinsically safe environmental perception camera in an embodiment of this application is as follows: When it is necessary to clean the lens glass 3, the sealing part 62 reduces the air pressure in the hollow cylinder wall of the corrugated sealing cylinder 61, so that the corrugated sealing cylinder 61 only fits on the lens glass 3. The rotating assembly 5 drives the lens glass 3 to rotate 180 degrees. The sealing part 62 drives the corrugated sealing cylinder 61 to press tightly against the lens glass 3 again. The liquid spraying part 41 sprays a cleaning agent on the cleaning part of the lens glass 3. Then, the scrubbing electric cylinder 424 drives the scrubbing frame 421 to fit on the lens glass 3, causing the scrubbing motor 422 to act. The scrubbing motor 422 drives the gear 4222 and the sponge scrubber 423 to rotate. Driven by the meshing of the rack 4221, the sponge scrubber 423 rotates and moves at the same time. The sponge scrubber 423 scrubs the lens glass 3 with the help of the cleaning agent. After scrubbing, the scraping motor 434 is actuated. The scraping motor 434 drives the scraping strip 431 to move. At the same time, the sponge scrubber 423 vacates a moving space for the scraping strip 431. The scraping strip 431 scrapes off the cleaning agent and oil stains and dust from the lens glass 3 together, so that the cleaning of the oil stains and dust on the lens glass 3 does not delay the shooting operation of the camera easily.

[0059] The above are all preferred embodiments of this application. The protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
