[0031] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0032] See also Figure 1-12A monitoring device with a self-cleaning function provided by an embodiment of the present invention includes a camera 34 and a self-cleaning mechanism installed on the camera 34. The self-cleaning mechanism includes a cover plate 1, a light-transmitting protective plate 2, a cleaning component and a driving component. The cover plate 1 is fixedly installed on the camera 34 and is located in front of the lens of the camera 34. A window for exposing the lens is provided in the middle of the cover plate 1. A groove is provided on the front side of the cover plate 1, that is, the side of the cover plate 1 away from the camera 34 along the length direction of the cover plate 1. The light-transmitting protective plate 2 is movably embedded in the groove of the cover plate 1 and is slidably connected to the front side of the cover plate 1 along the length direction of the cover plate 1. A dustproof and rainproof shell 33 is installed on the outside of the self-cleaning mechanism to protect the self-cleaning mechanism and the lens.

[0033] See also Figure 4 , wherein the light-transmitting protective plate 2 includes a first area and a second area connected to each other, and the sliding stroke of the light-transmitting protective plate 2 has a first protection position in which the first area covers the front of the lens, and a second protection position in which the second area covers the front of the lens; two ends of the light-transmitting protective plate 2 are respectively fixedly connected with a dustproof cloth 3, that is, a dustproof cloth 3 fixedly connected to the end of the light-transmitting protective plate 2 away from the second area and a dustproof cloth 3 fixedly connected to the end of the light-transmitting protective plate 2 away from the first area, and the ends of the two dustproof cloths 3 away from the light-transmitting protective plate 2 are bent around the end of the cover plate 1 and then connected on the back of the cover plate 1 by a draw rope 4, so that when the light-transmitting protective plate 2 slides along the length direction of the cover plate 1, the two dustproof cloths 3 slide around the circumference of the back plate driven by the light-transmitting protective plate 2.

[0034] When the light-transmitting protective plate 2 is in the first protection position, the dust-proof cloth 3 fixedly connected to the end of the light-transmitting protective plate 2 away from the second area covers the front area of ​​the cover plate 1 not covered by the light-transmitting protective plate 2, preventing dust from entering the groove of the cover plate 1 and contacting the side of the light-transmitting protective plate 2 close to the camera 34, causing the lens to be dirty when the light-transmitting protective plate 2 slides along the length direction of the cover plate 1, while the dust-proof cloth 3 fixedly connected to the end of the light-transmitting protective plate 2 away from the first area slides along the peripheral side of the cover plate 1 and is stored on the back side of the cover plate 1; When the light-transmitting protective plate 2 is in the second protection position, the dust-proof cloth 3 fixedly connected to the end of the light-transmitting protective plate 2 away from the first area covers the front area of ​​the cover plate 1 not covered by the light-transmitting protective plate 2, preventing dust from entering the groove of the cover plate 1 and contacting the side of the light-transmitting protective plate 2 close to the camera 34, causing the lens to be dirty when the light-transmitting protective plate 2 slides along the length direction of the cover plate 1, while the dust-proof cloth 3 fixedly connected to the end of the light-transmitting protective plate 2 away from the second area slides along the peripheral side of the cover plate 1 and is stored in the back side of the cover plate 1.

[0035] See also Figure 3, wherein the cleaning component is slidably connected to the side of the cover plate 1 along the length direction of the cover plate 1, and the cleaning component has a first cleaning station for cleaning the second area of ​​the light-transmitting protective plate 2 located at the first protection station during the sliding stroke, and a second cleaning station for cleaning the first area of ​​the light-transmitting protective plate 2 located at the second protection station, that is: the cleaning component has a first cleaning station and a second cleaning station during the sliding stroke, and when the cleaning component is at the first cleaning station, it cleans the second area of ​​the light-transmitting protective plate 2 located at the first protection station; when the cleaning component is at the second cleaning station, it cleans the first area of ​​the light-transmitting protective plate 2 located at the second protection station. The cleaning component includes a cleaning box 19, a scissor-type telescopic arm 20, a cleaning unit, and a winding drive member, and the cleaning box 19 is slidably installed on the long side of the cover plate 1 along the length direction of the cover plate 1, and one end of the scissor-type telescopic arm 20 is installed in the cleaning box 19, and the other end is connected to the cleaning unit. The cleaning unit includes a tripod 21 connected to the scissor-type telescopic arm 20, and the three corners of the tripod 21 are rotatably connected to a storage roller 22, an abutment roller 23 and a driving roller 24 in sequence. A clockwork spring 26 is arranged between the storage roller 22 and the tripod 21, and one end of the clockwork spring 26 is fixedly connected to the storage roller 22, and the other end of the clockwork spring 26 is fixedly connected to a side of the tripod 21 close to the storage roller 22. The clockwork spring 26 is arranged for winding the cleaning cloth tape 25 onto the storage roller 22, and the storage roller 22 is wound with the cleaning cloth tape 25, and the other end of the cleaning cloth tape 25 is fixedly connected to the driving roller 24 after passing the abutment roller 23, and the abutment roller 23 makes the cleaning cloth tape 25 adhere to the front side of the light-transmitting protective plate 2, and the winding drive is used to drive the driving roller 24 to rotate to wind up the cleaning cloth tape 25 after cleaning.

[0036] In one embodiment of the winding drive member provided by the present invention, the winding drive member includes a self-locking motor fixedly mounted on a tripod 21, and the rotating shaft of the self-locking motor is coaxially fixedly connected to a driving roller 24. When the light-transmitting protective plate 2 is cleaned, the scissor-type telescopic arm 20 in the cleaning box 19 is extended to drive the cleaning unit out of the cleaning box 19. Two winding methods can be used during the cleaning process. One is that when the cleaning unit is moving out of the cleaning box 19, the self-locking motor is turned on, and the rotating shaft of the self-locking motor drives the driving roller 24 to rotate, and the cleaning cloth belt 25 that becomes dirty after cleaning in contact with the light-transmitting protective plate 2 during the cleaning process or has a poor cleaning effect is rotated and wound into the driving roller 24, and the clean cleaning cloth belt 25 stored in the storage roller 22 is transmitted to the abutting roller 23. After the cleaning is completed, the scissor-type telescopic arm 20 is extended to drive the cleaning unit out of the cleaning box 19. The arm 20 contracts, driving the cleaning unit to move into the cleaning box 19, the self-locking motor is turned off, the rotating shaft of the self-locking motor is automatically locked, and the driving roller 24 is also locked and stopped to prevent the unclean cleaning tape 25 wound on the driving roller 24 from being wound back into the receiving roller 22; another way is that during the travel of the cleaning unit out of the cleaning box 19, the self-locking motor is turned off, and during the process of the cleaning unit moving into the cleaning box 19, the self-locking motor is turned on, and the cleaning tape 25 that has become dirty after cleaning in contact with the light-transmitting protective plate 2 during the cleaning process or has a poor cleaning effect is wound into the driving roller 24, and the clean cleaning tape 25 stored in the receiving roller 22 is transmitted to the abutting roller 23, and then the self-locking motor is turned off to prevent the unclean cleaning tape 25 wound on the driving roller 24 from being wound back into the receiving roller 22.

[0037] In another embodiment of the winding drive member provided by the present invention, please refer to Figure 8-12 The winding driving member includes two gears 27 fixedly mounted on both ends of the driving roller 24, two racks 29 fixedly connected to both ends of the cover plate 1, and at least one pawl 28 elastically rotatably connected to the tripod 21. The pawl 28 is rotatably connected to the corresponding tripod 21 through a rotating shaft 30. A torsion spring 31 is movably sleeved on the rotating shaft 30. One end of the torsion spring 31 is fixedly connected to the corresponding tripod 21, and the other end of the torsion spring 31 is fixedly connected to the pawl 28. A stopper 32 is fixedly connected to the tripod 21 corresponding to the pawl 28. The process of restoring the deformation of the torsion spring 31 drives the pawl 28 to rotate and abut against the stopper 32. When the cleaning component is located at the first cleaning station and the scissor-type telescopic arm 20 drives the cleaning unit out of the cleaning box 19, one of the gears 27 engages with the rack 29 at the corresponding position; when the cleaning component is located at the second cleaning station and the scissor-type telescopic arm 20 drives the cleaning unit out of the cleaning box 19, the other gear 27 engages with the corresponding rack 29; when the two gears 27 are disengaged from the two racks 29, the ratchet 28 engages with one of the gears 27.

[0038] When the cleaning assembly is located at the first cleaning station or the second cleaning station, the scissor-type telescopic arm 20 is unfolded to drive the cleaning unit out of the cleaning box 19, a gear 27 on the driving roller 24 meshes with the rack 29 at the corresponding position at this time, thereby driving the driving roller 24 to rotate, so that the clean cleaning cloth belt 25 on the storage roller 22 is continuously transported to the abutment roller 23 to clean the light-transmitting protective plate 2, and at the same time, the cleaning cloth belt 25 is continuously wound onto the driving roller 24, so that the effect of cleaning the light-transmitting protective plate 2 is better. During this period, the rotating gear 27 enables the pawl 28 to overcome the elastic force of the torsion spring 31 and avoid the gear teeth of the gear 27, so that the gear 27 can rotate smoothly; when cleaning is completed, the driving assembly drives the cleaning assembly to slide relative to the cover plate 1 to separate from the current position. The cleaning belt 25 is then moved away from the first cleaning station or the second cleaning station by a small distance, so that the current gear 27 is disengaged from the corresponding rack 29, and the clockwork spring 26 on the storage roller 22 has a tendency to rewind the cleaning tape 25 back onto the storage roller 22, that is, it has a tendency to drive the gear 27 to reverse. At this time, the pawl 28 abuts against the block 32, so that the pawl 28 and the gear 27 are engaged and the gear 27 cannot rotate, thereby locking the driving roller 24 in the reverse direction to prevent the driving roller 24 from rotating in the reverse direction and releasing the contaminated cleaning belt 25; then the scissor-type telescopic arm 20 contracts to drive the cleaning unit into the cleaning box 19, and the storage roller 22 collects the excess cleaning belt 25 that has not been wiped off the light-transmitting protective plate 2 between it and the abutting roller 23.

[0039] See also Figure 5-7 , wherein the driving assembly is used to drive the light-transmitting protective plate 2 and the cleaning assembly to slide relative to the cover plate 1, respectively. The driving assembly includes a driving shaft 5, a first fixed shaft 8, a second fixed shaft 9, a first movable rod 10, a second movable rod 11 and a driving motor 12. The driving shaft 5 is rotatably connected to a mounting plate 35 fixedly connected to the cover plate 1. A fixed rod 13 is fixedly connected to the mounting plate 35, and the driving shaft 5 is rotatably connected to the fixed rod 13. A first swing rod 6 and a second swing rod 7 are fixedly connected to the driving shaft 5. The first swing rod 6 and the second swing rod 7 are parallel and face the same direction. The first fixed shaft 8 and the second fixed shaft 9 are both fixedly connected to the mounting plate 35, and the first fixed shaft 8, the second fixed shaft 9 and the driving shaft 5 are located on the same straight line, and the straight line is parallel to the axis of the lens.

[0040] One end of the first movable rod 10 is rotatably connected to the middle of the long side of the light-transmitting protective plate 2, and the other end of the first movable rod 10 is slidably connected to the first fixed shaft 8. A fourth slide groove 40 is provided on the side of the cover plate 1 along the length direction. A cylindrical fourth column 15 is fixedly connected to the end of the first movable rod 10 away from the first fixed shaft 8. The other end of the fourth column 15 is rotatably connected to the middle of the long side of the light-transmitting protective plate 2, and the fourth column 15 is slidably arranged in the fourth slide groove 40. The first movable rod 10 is slidably connected to the end of the first swing rod 6 away from the driving shaft 5 along the length direction. A first slide groove 37 is provided on the first movable rod 10. A cylindrical first column 41 is provided at the end of the first swing rod 6 away from the driving shaft 5. The first column 41 is slidably arranged in the first slide groove 37.

[0041] One end of the second movable rod 11 is rotatably connected to the middle part of the cleaning assembly, and the other end of the second movable rod 11 is slidably connected to the second fixed shaft 9. A third slide groove 39 is provided on the cleaning box 19, and a slide rail 36 is provided on the long side of the cover plate 1 along the length direction. The cleaning box 19 is slidably connected to the slide rail 36 through the third slide groove 39. The end of the second movable rod 11 away from the second fixed shaft 9 is fixedly connected to a cylindrical third column rod 14, and the third column rod 14 is rotatably connected to the middle part of the cleaning box 19. The second movable rod 11 is slidably connected to the end of the second swing rod 7 away from the driving shaft 5 along the length direction. A second slide groove 38 is provided on the second movable rod 11, and a cylindrical second column rod 42 is provided at the end of the second swing rod 7 away from the driving shaft 5. The second column rod 42 is slidably set in the second slide groove 38.

[0042] The driving motor 12 is fixedly connected to the mounting plate 35. The rotating shaft of the driving motor 12 drives the driving shaft 5 to rotate through a belt assembly. The belt assembly includes a driving wheel 16, a driven wheel 17 and a belt 18. The driving wheel 16 is fixedly connected to the rotating shaft of the driving motor 12, the driven wheel 17 is fixedly connected to the driving shaft 5, and the belt 18 transmission sleeve is arranged on the driving wheel 16 and the driven wheel 17. When the driving assembly drives the light-transmitting protection plate 2 and the cleaning assembly to slide relative to the cover plate 1, the rotating shaft of the driving motor 12 drives the belt 18 on the driving wheel 16 to rotate, and the rotation of the belt 18 drives the driven wheel 17 to rotate. The rotation of the driven wheel 17 drives the driving shaft 5 to rotate, and the driving shaft 5 rotates to drive the first swing rod 6 and the second swing rod 7 on the driving shaft 5 to rotate. While the first swing rod 6 rotates, it abuts and cooperates with the first fixed shaft 8, driving the first movable rod 10 that is slidably connected to the end of the first swing rod 6 away from the driving shaft 5 to perform reciprocating swinging motion. During the reciprocating swinging motion of the first movable rod 10, the fourth column 15 on the first movable rod 10 slides back and forth in the fourth slide groove 40, and at the same time, the light-transmitting protection plate 2 that is rotatably connected to the fourth column 15 also slides back and forth in the cover plate 1 along the length direction of the cover plate 1, so that the light-transmitting protection plate 2 can switch back and forth between the first protection station and the second protection station.

[0043] When the second swing rod 7 rotates, it abuts against the second fixed shaft 9, driving the second movable rod 11 that is slidably connected to the end of the second swing rod 7 away from the driving shaft 5 to perform reciprocating swinging motion. During the reciprocating swinging motion of the second movable rod 11, the third column rod 14 on the second movable rod 11 drives the cleaning assembly to slide back and forth along the length direction of the cover plate 1 on the slide rail 36, so that the cleaning assembly can switch back and forth between the first cleaning station and the second cleaning station. During the sliding of the light-transmitting protective plate 2 and the cleaning assembly relative to the cover plate 1, the first swing rod 6 is parallel to the second swing rod 7 and faces the same direction. At the same time, the first movable rod 10 driven by the first swing rod 6 and the second movable rod 11 driven by the second swing rod 7 are parallel to each other and face the same direction. This parallel structure makes it possible for the first cleaning station of the cleaning assembly to be exactly opposite to the second area of ​​the light-transmitting protective plate 2 located at the first protection station when the light-transmitting protective plate 2 is located at the second protection station; when the light-transmitting protective plate 2 is located at the second protection station, the second cleaning station of the cleaning assembly is exactly opposite to the first area of ​​the light-transmitting protective plate 2 located at the second protection station.

[0044] In addition, the self-cleaning mechanism in the embodiment of the present invention can be detachably connected to the camera 34. In this way, when the self-cleaning mechanism fails and needs to be repaired or the cleaning tape 25 needs to be replaced, it is only necessary to remove the self-cleaning mechanism from the camera 34, thereby broadening the scope of use of the embodiment of the present invention and providing convenience for the subsequent repair of the parts of the cleaning mechanism or the replacement of the cleaning tape 25.

[0045] Working principle: The driving component drives the light-transmitting protective plate 2 to switch between the first protection station and the second protection station, so that the first area and the second area of ​​the light-transmitting protective plate 2 alternately cover the front of the lens of the camera 34 to protect the lens. When the light-transmitting protective plate 2 is located at the first protection station, the driving component drives the cleaning component to slide to the first cleaning station to clean the second area of ​​the light-transmitting protective plate 2. During the cleaning process, the cleaning cloth belt 25 on the abutting roller 23 is attached to the second area of ​​the light-transmitting protective plate 2, and the abutting roller 23 is driven to reciprocate up and down by expanding and contracting the scissor-type telescopic arm 20 to clean the second area of ​​the light-transmitting protective plate 2.

[0046] When the light-transmitting protective plate 2 is located at the second protection station, the driving component drives the cleaning component to slide to the second cleaning station to clean the first area of ​​the light-transmitting protective plate 2. During the cleaning process, the cleaning cloth belt 25 on the abutment roller 23 fits with the first area of ​​the light-transmitting protective plate 2, and the abutment roller 23 is driven to reciprocate up and down by expanding and contracting the scissors-type telescopic arm 20 to clean the first area of ​​the light-transmitting protective plate 2.

[0047] At the same time, during the cleaning process, the winding drive member in the cleaning component transports the cleaning cloth tape 25 on the receiving roller 22 to the abutment roller 23, and the cleaning cloth tape 25 bypasses the abutment roller 23 and fits the light-transmitting protective plate 2. The cleaning cloth tape 25 after cleaning is wound onto the driving roller 24 to prevent the contaminated cleaning cloth tape 25 from being reversely wound onto the receiving roller 22, and to avoid repeatedly cleaning the light-transmitting protective plate 2 with the same area of ​​the cleaning cloth tape 25, so as to achieve a better cleaning effect, and the camera 34 will not be blocked during the cleaning process of the cleaning component.

[0048] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
