[0002] In order to comprehensively monitor safety hazards in mines, mining cameras will be integrated with gas sensors, carbon monoxide sensors, oxygen sensors and temperature sensors, so that mining cameras can perceive and monitor the mine environment from multiple angles, so that mining cameras can be used in coal mining seams to comprehensively perceive safety hazards that may occur during the coal mining process.

[0003] Existing mining cameras are usually provided with a cleaning mechanism, for example, Chinese patent publication number CN221408963U discloses a mining intrinsically safe camera, and Chinese patent publication number CN222423814U discloses a mining dust removal camera. The cleaning mechanism can scrub and clean the lens glass of the camera to prevent dust from blocking the lens glass of the camera.

[0036] The following is combined with Figure 1-9 This application is described in further detail.

[0037] The embodiment of the present application discloses a mine-use intrinsically safe environment perception camera. Figure 1 、 Figure 2 and Figure 3 A mine-used intrinsically safe environment sensing 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.

[0038] Reference Figure 1 and Figure 2 The explosion-proof housing 1 is provided with a shooting hole 11. The partition housing 2 is fixedly mounted in the explosion-proof housing 1 and is arranged near the shooting hole 11. The partition housing 2 divides the explosion-proof housing 1 into two spaces. The space near the shooting hole 11 is a clean room 21, and the space away from the shooting hole 11 is a camera room 22. The camera room 22 is provided with a camera body 23 for capturing surveillance images.

[0039] Reference Figure 2 The lens glass 3 is in the shape of a circular plate and is rotatably set at the rotating hole 24 opened on the partition shell 2. Half of the lens glass 3 is set facing the lens of the camera 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.

[0040] Reference Figure 3 and Figure 4In order to enhance the sealing between the lens glass 3 and the partition shell 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 fixed in the sealing groove 25 and squeezed on the side of the lens glass 3.

[0041] Reference Figure 2 and Figure 3 The cleaning assembly 4 is disposed in the cleaning chamber 21 , and the cleaning assembly 4 includes a liquid spraying portion 41 , a scrubbing portion 42 and a scraping portion 43 .

[0042] The liquid spraying part 41 is connected to the explosion-proof shell 1 and is used to spray detergent on both sides of the cleaning part of the lens glass 3. The scrubbing part 42 is set on the explosion-proof shell 1 and is used to scrub both sides of the cleaning part of the lens glass 3 with the help of detergent. The scraping part 43 is set on the scrubbing part 42 and is used to scrape the detergent 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 scraping part 43 to move.

[0043] Reference Figure 3 The rotating assembly 5 is connected to the partition shell 2 and the lens glass 3 respectively, and the rotating assembly 5 is used to drive the lens glass 3 to rotate 180 degrees.

[0044] Reference Figure 2 The sealing assembly 6 includes a corrugated sealing cylinder 61 and a sealing portion 62.

[0045] Reference 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 shell 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 against the lens glass 3. When the lens glass 3 rotates, the sealing part 62 is used to release the corrugated sealing cylinder 61 from pressing against the lens glass 3.

[0046] During use, after oil stains and dust stains adhere to the area facing the lens glass 3 and the corrugated sealing tube 61, the sealing part 62 releases the pressing force between the corrugated sealing tube 61 and the lens glass 3, so that the lens glass 3 is in a rotatable state. At this time, the corrugated sealing tube 61 and the lens glass 3 are in a fitted state, and then the rotating component 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 where oil stains and dust stains adhere can be located in the cleaning chamber 21. After the lens glass 3 rotates 180 degrees, the sealing part 62 makes the corrugated sealing tube 61 press against the lens glass 3 again to re-seal the area between the shooting hole 11 and the lens glass 3.

[0047] The liquid spraying part 41 sprays the cleaning agent onto the two sides of the cleaning part of the lens glass 3, and the scrubbing part 42 scrubs the two sides of the cleaning part of the lens glass 3. With the help of the cleaning agent, the oil and dust stains on the lens glass 3 will gradually fall away from the lens glass 3, and then the scraping part 43 scrapes the two sides of the cleaning part of the lens glass 3 so that the cleaning agent and oil and dust stains on the lens glass 3 can be scraped off the lens glass 3. When the scraping part 43 scrapes the lens glass 3, the scrubbing part 42 can make room for the scraping part 43 to move. On the one hand, it makes it difficult for the scrubbing part 42 to stick the cleaning agent and oil and dust stains on itself to the lens glass 3, and on the other hand, it makes it difficult for the scraping process of the scraping part 43 to be hindered.

[0048] Based on the above analysis, after oil stains and dust stains 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 stains can be rotated to the cleaning component 4, and the clean part of the lens glass 3 can be rotated to a position facing the camera body 23, so that the cleaning of the lens glass 3 is not easy to interfere with the picture shooting of the camera body 23, so that during the long cleaning process of the lens glass 3, the camera body 23 can perform the shooting operation normally, so that the cleaning of the oil stains and dust stains on the lens glass 3 is not easy to delay the shooting operation of the camera.

[0049] Specifically, refer to Figure 2 The liquid spraying unit 41 includes a liquid storage box 411 , a spray pump 412 and a spray pipe 413 .

[0050] There are two liquid storage boxes 411, two jet pumps 412 and two jet pipes 413 symmetrically arranged. The liquid storage box 411 is used to store 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 jet pumps 412 are connected to the liquid storage boxes 411 one-to-one; one end of the jet pipe 413 is connected to the jet pump 412 one-to-one, and the other end is connected to two guide nozzles 414. The ends of the two guide nozzles 414 away from the jet pipe 413 are respectively directed to the two sides of the cleaning part of the lens glass 3.

[0051] When cleaning is required, the two jet pumps 412 operate simultaneously. The jet pumps 412 suck the detergent in the liquid storage box 411 into the spray pipe 413, and the detergent is sprayed onto the lens glass 3 from the guide nozzle 414, so that the detergent can be sprayed on both sides of the cleaning part of the lens glass 3 to facilitate cleaning of oil stains and dust.

[0052] Specifically, refer to Figure 3 The scrubbing portion 42 includes a scrubbing frame 421 , a scrubbing motor 422 and a sponge 423 .

[0053] Reference Figure 2 and Figure 3There are two scrubbing frames 421, scrubbing motors 422 and sponges 423 symmetrically arranged. The scrubbing frame 421 is a rectangular frame. The scrubbing frame 421 is located on the side of the lens glass 3 and is connected to the explosion-proof shell 1; the scrubbing motors 422 are connected to the scrubbing frame 421 one by one; the sponges 423 are fixedly connected to the output shafts of the scrubbing motors 422 one by one, and the sponges 423 are used to scrub the lens glass 3 after absorbing the detergent.

[0054] Among them, reference Figure 3 In order to enable the sponge 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 423 is fixedly connected to the support plate 4223 .

[0055] After spraying the detergent, the scrubbing motor 422 is activated, and the scrubbing motor 422 drives the sponge 423 to rotate. The sponge 423 absorbs the detergent and continuously scrubs the lens glass 3 during the rotation process. After a period of time, the sponge 423 can use the detergent to remove the oil stains and dust stains on the lens glass 3, thereby cleaning the oil stains and dust stains.

[0056] Reference Figure 3 and Figure 5 In order to expand the cleaning range of the sponge 423, the scrubbing motor 422 is slidably connected to the rack 4221, the rack 4221 is connected to the scrubbing frame 421, and a gear 4222 is fixedly connected to the output shaft of the scrubbing motor 422. The gear 4222 is engaged with the rack 4221, and the scrubbing motor 422 can drive the gear 4222 to rotate in forward and reverse directions.

[0057] When the scrubbing motor 422 drives the sponge 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 423 can move relative to the lens glass 3 during the rotation process. Since the scrubbing motor 422 can drive the gear 4222 to rotate in both directions, the sponge 423 can move back and forth, thereby expanding the cleaning range of the sponge 423, so that the half of the lens glass 3 suspended in the cleaning chamber 21 can be cleaned.

[0058] Reference Figure 3 and Figure 6 In order to enable the liquid spraying part 41 to spray the cleaning agent onto the lens glass 3 evenly and comprehensively, the scrubbing part 42 also includes a scrubbing electric cylinder 424, a scrubbing plate 425 and a scrubbing connecting rod 426.

[0059] Reference Figure 2 and Figure 6The scrubbing electric cylinder 424 is fixedly connected to the explosion-proof shell 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 they correspond one to one with the scrubbing frame 421, and the bottom end of the scrubbing frame 421 is hinged to the explosion-proof shell 1, one end of the scrubbing connecting rod 426 is fixedly connected to the scrubbing frame 421, and the other end is slidably set on the scrubbing plate 425; when the scrubbing electric cylinder 424 is extended, the two scrubbing frames 421 swing away from each other, and when the scrubbing electric cylinder 424 is retracted, the two scrubbing frames 421 swing towards each other, and the scrubbing frames 421 can fit on the lens glass 3.

[0060] Among them, reference Figure 6 The end of the scrubbing link 426 is fixedly connected with a round rod-shaped sliding rod 4261, and the sliding rod 4261 is slidably set 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 link 426 and the scrubbing plate 425.

[0061] Before spraying the detergent, the scrubbing electric cylinder 424 is extended, and the scrubbing electric cylinder 424 drives the scrubbing plate 425 to move toward the direction close to the lens glass 3. The scrubbing electric cylinder 424 can drive the sliding rod 4261 to slide in the sliding groove 4251. When sliding, the sliding rod 4261 can drive the scrubbing connecting rod 426 to swing. The scrubbing connecting rod 426 can drive the scrubbing frame 421 to swing, so that the scrubbing frame 421 can be rotated away from the lens glass 3, so that the sponge 423 is not easily blocked from spraying the detergent.

[0062] Specifically, refer to Figure 7 The scraping part 43 includes a scraping bar 431 , a lead screw 432 , a guide rod 433 and a scraping motor 434 .

[0063] There are two scraping strips 431, lead screws 432, guide rods 433 and scraping motors 434 symmetrically arranged, and each corresponds to the scrubbing frame 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. Both ends of the scraping strip 431 are fixedly connected with sliders 4311, and the sliders 4311 are slidably arranged in the slide grooves 4211 opened on the inner wall of the scrubbing frame 421; the lead screw 432 is threaded through one of the sliders 4311 and is rotatably connected to the scrubbing frame 421; the guide rod 433 is slidably arranged on the other slider 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.

[0064] After scrubbing is completed, the scraping motor 434 is activated, the scraping motor 434 drives the lead screw 432 to rotate, the lead screw 432 drives the slider 4311 to slide, the slider 4311 drives the scraping bar 431 and another slider 4311 to slide, and the scraping bar 431 can scrape off the detergent and oil stains on the lens glass 3 during the sliding process, so that the lens glass 3 can be cleaned.

[0065] Reference Figure 3 、 Figure 7 and Figure 8 In order to allow the sponge 423 to make room for movement when the scraper 431 is scraping the lens glass 3, both ends of the rack 4221 are fixedly connected with sliding rods 427, and the middle part of the sliding rod 427 is connected to the end of the rack 4221. The sliding rod 427 corresponds to the slider 4311 one by one. The sliding rod 427 is slidably arranged on the scrubbing frame 421 in the direction of approaching or moving away from the lens glass 3. A scrubbing spring 428 is fixed between the sliding rod 427 and the scrubbing frame 421. The scrubbing spring 428 is used to drive the sponge 423 to abut against the lens glass 3. A push rod inclined surface 4312 is provided on the slider 4311. When the slider 4311 slides, the slider 4311 can push the sliding rod 427 to slide away from the lens glass 3 through the push rod inclined surface 4312, so that the sponge 423 can make room for movement for the scraper 431.

[0066] When the scraper 431 is scraping, the push rod inclined surface 4312 on the slider 4311 can push the slide bar 427 to slide away from the lens glass 3, and the slide bar 427 can drive the sponge 423 to move away from the lens glass 3, so that the sponge 423 can make room for the movement of the scraper 431, and also make it difficult for the detergent and oil stains on the sponge 423 to stick to the lens glass 3 when the scraper 431 is scraping the lens glass 3; after the scraper 431 is reset, the slide bar 427 can reset the sponge 423 under the elastic force of the scrubbing spring 428.

[0067] Specifically, refer to Figure 9 The rotating assembly 5 includes a self-locking motor 51 , which is fixed to the partition shell 2 , and an output shaft of the self-locking motor 51 is connected to the lens glass 3 .

[0068] The self-locking motor 51 drives the lens glass 3 to rotate, so that the rotation angle of the lens glass 3 can be stabilized, so that the area of the lens glass 3 adhering to oil stains and dust stains can be stably located in the scrubbing area of the scrubbing portion 42.

[0069] Reference Figure 2 and Figure 9 In order to enable the two positions where the lens glass 3 and the camera body 23 face each other to be adjusted, the rotating assembly 5 further includes a fixing bolt 52 and a connecting pipe 53 .

[0070] Reference Figure 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.

[0071] After the lens glass 3 has been used for a long time, the fixing bolt 52 is tightened 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 tube 53, and then the lens glass 3 is rotated to change the position of the lens glass 3 that has been facing the corrugated sealing cylinder 61 for a long time, so that the position of the lens glass 3 that has not faced the corrugated sealing cylinder 61 before is now facing the corrugated sealing cylinder 61, so that the position of the lens glass 3 that faces the corrugated sealing cylinder 61 can be replaced.

[0072] Specifically, refer 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 .

[0073] Reference Figure 2 and Figure 3 The wall of the bellows sealing cylinder 61 is hollow. The sealed electric cylinder 621 and the sealing box 622 are both fixedly connected to the explosion-proof housing 1. The piston 623 is fixedly connected to the movable end of the sealed electric cylinder 621 and is slidingly arranged in a sealed manner within the sealing box 622. The end of the sealing box 622 closest to the sealed electric cylinder 621 is open. The end of the sealing box 622 away from the sealed electric cylinder 621 is connected to one end of an air pipe 624. The other end of the air pipe 624 is connected to the hollow wall of the bellows sealing cylinder 61. The air pipe 624 allows air to flow between the sealing box 622 and the bellows sealing cylinder 61.

[0074] When it is necessary to release the tight contact between the bellows sealing cylinder 61 and the lens glass 3, the sealing electric cylinder 621 is contracted, and the sealing electric cylinder 621 drives the piston 623 to slide. The piston 623 sucks the air in the bellows sealing cylinder 61 into the sealing box 622 through the air pipe 624, so that the air pressure in the hollow cylinder wall of the bellows sealing cylinder 61 is reduced, so that the bellows sealing cylinder 61 can only fit on the lens glass 3; when it is necessary to make the bellows sealing cylinder 61 and the lens glass 3 press tightly, the sealing electric cylinder 621 is extended, and the sealing electric cylinder 621 drives the piston 623 to slide in the opposite direction, and the piston 623 pushes the air in the sealing box 622 into the hollow cylinder wall of the bellows sealing cylinder 61 to increase the air pressure in the hollow cylinder wall of the bellows sealing cylinder 61, so that the bellows sealing cylinder 61 can press tightly against the lens glass 3.

[0075] The implementation principle of the intrinsically safe environment perception camera for mining in the embodiment of the present application is as follows: when the lens glass 3 needs to be cleaned, the sealing portion 62 reduces the air pressure in the hollow wall of the corrugated sealing cylinder 61, so that the corrugated sealing cylinder 61 is only attached to the lens glass 3, the rotating assembly 5 drives the lens glass 3 to rotate 180 degrees, the sealing portion 62 drives the corrugated sealing cylinder 61 to press against the lens glass 3 again, the liquid spraying portion 41 sprays the cleaning agent to the cleaning part of the lens glass 3, and then the scrubbing electric cylinder 424 drives the scrubbing frame 421 to attach to the lens glass 3, so that the scrubbing motor 422 is activated. The scrubbing motor 422 drives the gear 4222 and the sponge 423 to rotate. Under the meshing drive of the rack 4221, the sponge 423 rotates and moves. The sponge 423 scrubs the lens glass 3 with the help of the detergent. After scrubbing, the scraping motor 434 is activated, and the scraping motor 434 drives the scraping bar 431 to move. At the same time, the sponge 423 makes room for the scraping bar 431 to move. The scraping bar 431 scrapes the detergent and oil stains from the lens glass 3 together, so that the cleaning of the oil stains on the lens glass 3 is not easy to delay the shooting operation of the camera.

[0076] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
