[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0032] Refer to Figures 1 - 5 , an embodiment provided by the present invention: A safety monitoring and alarm camera device, including a mounting plate 1, a camera 2 is fixedly connected to one side of the mounting plate 1, a fixing bracket 3 is fixedly connected to the other side of the mounting plate 1, and holes corresponding to and adapted to mounting bolts are formed on the fixing bracket 3. The camera device can be conveniently fixed at the installation location by means of the holes and the mounting bolts. A plurality of support rods 4 are fixedly connected to the outer edge of the mounting plate 1, a positioning ring 5 is fixedly connected between the plurality of support rods 4, and a movable ring 6 is slidably connected between the outer circumferences of the plurality of support rods 4. Through the high-strength support structure formed by the plurality of support rods 4, the movable ring 6 can reciprocate along the support rods 4, so that the movable ring 6 can move outside the camera 2 without affecting and interfering with the camera 2. A rotating ring 7 is rotatably connected inside the movable ring 6, an external gear ring 8 is fixedly connected to the outside of the rotating ring 7, a plurality of connecting frames 9 are fixedly connected to the inside of the rotating ring 7, a rotating shaft 10 is rotatably connected to the inside of the connecting frames 9, a brush plate 11 is fixedly connected to the middle of the outer circumference of the rotating shaft 10, and torsion springs 12 are sleeved on both sides of the outer circumference of the rotating shaft 10. Through the torsional force exerted by the torsion springs 12 on the brush plate 11, the brush plate 11 can tightly adhere to the outer shell of the camera 2. By moving the movable ring 6 on the support rods 4 to drive the brush plate 11 to move, the dust attached to the outer shell of the camera 2 can be cleaned.
[0033] Refer to Figures 1 - 5, a tooth column 13 is rotatably connected to one side between the positioning ring 5 and the mounting plate 1, and a reciprocating lead screw 14 is rotatably connected to the other side between the positioning ring 5 and the mounting plate 1. The outer circumference of the reciprocating lead screw 14 is threadedly connected to the inside of the movable ring 6. One ends of the tooth column 13 and the reciprocating lead screw 14 away from the positioning ring 5 are fixedly connected with worm gears 15. The middle of the fixed frame 3 is fixedly connected with a mounting frame 16. Inside the mounting frame 16, a motor 17 is fixedly connected. The output end of the motor 17 is fixedly connected with a worm 18, and the worm 18 meshes with the two worm gears 15. When the motor 17 is started, it will drive the worm 18 to rotate. The rotation of the worm 18 will drive the two meshing worm gears 15 to rotate. The two rotating worm gears 15 will respectively drive the tooth column 13 and the reciprocating lead screw 14 to rotate. By the rotation of the reciprocating lead screw 14, the movable ring 6 can be driven to reciprocate left and right on the outer circumference of the support rod 4. At the same time, the rotating tooth column 13 will also drive the outer gear ring 8 to drive the rotating ring 7 to rotate, so that the rotating ring 7 can rotate inside the movable ring 6. Then, while the rotating ring 7 rotates to drive the brush plate 11 to rotate to clean the dust or other impurities on the outer shell of the camera 2, the movable ring 6 will also push the brush plate 11 to reciprocate left and right on the outer shell of the camera 2, and then clean the front of the camera 2. The tooth column 13 meshes with the outer gear ring 8. Through the tooth column 13, the outer gear ring 8 can be driven to rotate by it, ensuring that the rotating ring 7 can rotate inside the movable ring 6. A collection component is installed outside the mounting frame 16, and the collection component is used to collect the floating dust.
[0034] Refer to Figures 1 - 5 , the tooth column 13 penetrates through the inside of the movable ring 6, and the outside of the tooth column 13 is slidably connected to the outside of the outer gear ring 8. When the movable ring 6 drives the rotating ring 7 and the outer gear ring 8 to move synchronously, the tooth column 13 can always drive the outer gear ring 8 to rotate, so as to realize the rotation of the rotating ring 7 inside the movable ring 6. The brush plate 11 abuts against the camera 2, so that the brush plate 11 can clean the dust on the outer shell of the camera 2 when it moves. One end of the worm 18 away from the motor 17 is rotatably connected to the inner wall of the mounting frame 16, so that the motor 17 can stably drive the worm 18 to rotate. One end of the torsion spring 12 is fixedly connected to the outer wall of the brush plate 11, and the other end of the torsion spring 12 is fixedly connected to the inner wall of the connecting frame 9, so that the torsion spring 12 will always apply a torsional force to the brush plate 11 in the direction of the camera 2, ensuring that the brush plate 11 is in close contact with the outer shell part of the camera 2. One ends of the tooth column 13 and the reciprocating lead screw 14 away from the positioning ring 5 both penetrate through the mounting plate 1, and the two worm gears 15 are both arranged inside the mounting frame 16, so that the worm gears 15 and the worm 18 are both inside the mounting frame 16, effectively preventing dust from entering between the worm gears 15 and the worm 18.
[0035] Refer to Figures 1 - 3, the collection component includes a dust-proof housing 19, a filter box 22 and an annular pipe 23. The outer side of the dust-proof housing 19 is fixedly connected to the outer wall of the mounting frame 16. A dust-proof net 20 is fixedly connected to the side of the dust-proof housing 19 away from the camera 2. A fan blade 21 is rotatably connected inside the dust-proof housing 19. The middle of the fan blade 21 is fixedly connected to the end of the worm 18 away from the motor 17. The bottom of the filter box 22 is fixedly connected to the top of the camera 2. The outer side of the annular pipe 23 is fixedly connected to the side of the movable ring 6 away from the camera 2. A plurality of uniformly distributed dust suction heads 24 are installed outside the annular pipe 23. The worm 18 drives the fan blade 21 inside the dust-proof housing 19 to rotate. Through the rotation of the fan blade 21, the air inside the dust-proof housing 19 is continuously discharged to the outside through the gaps of the dust-proof net 20, making a negative pressure environment inside the dust-proof housing 19. Furthermore, a negative pressure state is also formed inside the dust suction head 24, so that the floating dust swept by the brush plate 11 will be sucked into the dust suction head 24. Subsequently, the sucked dust enters the inside of the annular pipe 23 and enters the inside of the filter box 22 along the pipeline. Then, the dust is blocked by the filtering structure inside the filter box 22. After the brush plate 11 sweeps, the floating dust will not adhere to the surface and lens of the camera 2 again. There is a pipeline connecting the inside of the filter box 22 and the inside of the dust-proof housing 19, and there is a pipeline connecting the inside of the filter box 22 and the inside of the annular pipe 23. When a negative pressure is formed inside the dust-proof housing 19, the floating dust near the camera 2 will be sucked into the dust suction head 24, and then enter the inside of the filter box 22 through the pipeline between the annular pipe 23 and the filter box 22, so that the dust in the air is blocked by the filter box 22. A plurality of brush plates 11 are all arranged inside the annular pipe 23, so that the floating dust generated when the brush plates 11 sweep will be collected by the dust suction heads 24 on the annular pipe 23 in the first time.
[0036] Working principle: When there is a lot of dust accumulated on the camera 2, the worm 18 is driven to rotate by starting the motor 17, and then the two worm wheels 15 are driven to rotate synchronously by the rotation of the worm 18, so that the tooth column 13 and the reciprocating screw 14 rotate synchronously. When the reciprocating screw 14 rotates, it will drive the movable ring 6 to continuously move back and forth on the outer periphery of the support rod 4. At the same time, the rotating tooth column 13 will drive the outer gear ring 8 to rotate inside the movable ring 6, so that the rotating ring 7 moves back and forth along the outer side of the camera 2 while rotating. The brush plate 11 installed on the rotating shaft 10 is driven by the rotating ring 7 to move in a circular motion to clean the dust and other impurities attached to the outer wall of the camera 2. When the brush plate 11 moves to the lens of the camera 2 along with the movable ring 6, the left end of the brush plate 11 lacks the support of the camera 2, so that the brush plate 11 will deflect toward the lens of the camera 2 under the action of the torsion spring 12, and then the brush plate 11 will switch from a horizontal state to a vertical state, and the dust at the lens of the camera 2 will be cleaned by the rotation of multiple brush plates 11. Then the reciprocating screw 14 continues to rotate so that the movable ring 6 will reset and move toward the direction of the mounting plate 1. At this time, the bottom of the brush plate 11 contacts the edge of the end of the camera 2, and the flipped brush plate 11 is pulled again and restored to a horizontal state under the pull of the movable ring 6, and finally moves to the side of the mounting plate 1, ensuring that after the dust on the surface of the camera device is cleaned, the cleaning structure will not affect the normal operation of the camera device.
[0037] At the same time, when the worm 18 drives the two worm wheels 15 to rotate, the worm 18 also drives the fan blades 21 inside the dustproof shell 19 to rotate, and the air inside the dustproof shell 19 is continuously discharged to the outside through the gaps of the dustproof net 20 through the rotation of the fan blades 21, so that a negative pressure environment is formed inside the dustproof shell 19, and then a negative pressure state is formed inside the dust suction head 24, so that the flying dust cleaned by the brush plate 11 will be sucked into the dust suction head 24, and then the sucked dust enters the annular tube 23 and enters the filter box 22 along the pipeline, and then the dust is blocked by the filter structure inside the filter box 22. After the brush plate 11 cleans, the flying dust will not be attached to the surface and lens of the camera 2 for a second time.
[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
