[0042] 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 introduced in detail below in conjunction with the accompanying drawings.

[0043] Embodiment 1: Please refer to Figure 1 - Figure 4 , a video monitoring device for an environmental noise monitoring system, including a camera main body 1, and further including:

[0044] A housing 2, which is installed on the top of the camera main body 1;

[0045] Two glass lenses 3, one of the glass lenses 3 is attached to the outer surface of the lens of the camera main body 1, and the other glass lens 3 is located inside the housing 2, and the glass lens 3 is used to prevent dust and impurities from directly adhering to the surface of the lens of the camera main body 1;

[0046] An exchange mechanism is installed inside the housing 2 and is used to exchange the positions of two glass lenses 3. The exchange mechanism includes a lifting block 4 arranged inside the housing 2, a first transmission shaft 5 rotatably connected inside the lifting block 4, a connecting bar 6 fixedly sleeved outside the first transmission shaft 5, a lifting assembly for driving the first transmission shaft 5 to move up and down, and a flipping assembly for driving the first transmission shaft 5 to rotate. The friction between the first transmission shaft 5 and the lifting block 4 is relatively large, and the first transmission shaft 5 will not rotate without external force driving. The connecting bar 6 is fixedly connected between the two glass lenses 3. The lifting assembly includes a first driving shaft 8 rotatably connected inside the housing 2 along the height direction of the housing 2, a first reciprocating screw 9 fixedly sleeved outside the first driving shaft 8, and a motor 10 installed on the inner wall of the top of the housing 2. The lifting block 4 is screwed outside the first reciprocating screw 9. A guide rod 11 parallel to the first driving shaft 8 is also fixedly connected inside the housing 2, and the lifting block 4 is also slidably sleeved outside the guide rod 11. A first gear 12 is fixedly sleeved outside the output shaft of the motor 10, and a first one-way gear 13 is installed outside the first driving shaft 8. The first gear 12 meshes with the first one-way gear 13. The first gear 12 is also connected to the flipping assembly.

[0047] When it is necessary to clean the glass lens 3 currently attached to the lens surface of the camera body 1, the motor 10 is controlled to drive the first gear 12 to rotate forward. Through the meshing action between the first gear 12 and the first one-way gear 13, the first driving shaft 8 is driven to rotate. At this time, the second one-way gear 21 also rotates accordingly, but the worm 17 does not rotate. When the first driving shaft 8 rotates, it drives the first reciprocating screw 9 to rotate synchronously, driving the lifting block 4 to move up from the bottom end of the first reciprocating screw 9 to the top end. During this process, the first transmission shaft 5, the connecting bar 6, and the two glass lenses 3 are driven to move up synchronously, so that the glass lens 3 attached to the lens surface of the camera body 1 moves up and enters the inside of the housing 2.

[0048] The first transmission shaft 5 is driven to rotate 180° by the flipping assembly, so that the positions of the two glass lenses 3 are exchanged. Then, the motor 10 is controlled to continue driving the first reciprocating screw 9 to rotate, driving the lifting block 4 to move down from the top end of the first reciprocating screw 9 to the bottom end. During this process, the replaced glass lens 3 is driven to fit the lens surface of the camera body 1.

[0049] The flipping assembly includes a second transmission shaft 14 rotatably connected inside the housing 2 along the length direction of the housing 2, a second reciprocating screw 15 fixedly sleeved outside the second transmission shaft 14, a moving block 16 screwed outside the second reciprocating screw 15, and a worm 17 rotatably connected inside the housing 2 along the height direction of the housing 2; a rack 18 is fixedly connected to the outer wall of one side of the moving block 16, a second gear 19 is fixedly sleeved outside the first transmission shaft 5, and the rack 18 is matched with the second gear 19; a worm gear 20 is fixedly sleeved outside the second transmission shaft 14, and the worm 17 is meshed with the worm gear 20; a second one-way gear 21 is installed outside the worm 17, and the second one-way gear 21 is meshed with the first gear 12;

[0050] After the glass lens 3 currently attached to the lens surface of the camera body 1 is moved up into the housing 2, the control motor 10 is driven to drive the first gear 12 to reverse. Through the meshing action between the first gear 12 and the second one-way gear 21, the worm 17 is driven to rotate. At this time, the first one-way gear 13 also rotates accordingly, but the first drive shaft 8 does not rotate accordingly. When the worm 17 rotates, through the meshing action between the worm 17 and the worm gear 20, the second transmission shaft 14 is driven to rotate, and the second reciprocating screw 15 rotates accordingly, driving the moving block 16 to move from the right end of the second reciprocating screw 15 to its left end. During this process, the rack 18 is driven to move synchronously. Since the second gear 19 follows the lifting block 4 and moves up to the lower side of the left side of the rack 18, when the rack 18 moves to the left, a meshing relationship is established with the second gear 19, driving the second gear 19 and the first transmission shaft 5 to rotate 180°, thereby exchanging the positions of the two glass lenses 3 through the connecting strip 6.

[0051] A through groove is formed between the camera body 1 and the housing 2 for passing the glass lens 3. A sealing strip 7 is fixedly connected to the outside of the connecting strip 6, and the sealing strip 7 is used to seal the through groove;

[0052] When the glass lens 3 is in normal use, the sealing strip 7 is inside the through groove. When the glass lens 3 moves upward, the sealing strip 7 moves upward synchronously into the housing 2. After the positions of the two glass lenses 3 are exchanged and the glass lens 3 is driven to move downward, the sealing strip 7 re-enters the inside of the through groove.

[0053] Embodiment 2: Please refer to Figure 2 、 Figure 5 and Figure 6, this embodiment provides a technical solution based on Embodiment 1: It includes a cleaning mechanism installed inside the housing 2 for cleaning the glass lens 3 that exchanges and enters the inside of the housing 2. The cleaning mechanism includes a spraying component and a wiping component, and the spraying component is connected to the moving block 16; the spraying component includes a liquid storage tank 22 installed inside the housing 2, an atomizing nozzle 23 arranged in front of the glass lens 3, and a liquid guiding cylinder 24 installed on the top of the liquid storage tank 22; a piston 25 is installed inside the liquid guiding cylinder 24, a linkage rod 26 is fixedly connected to the outer wall on one side of the piston 25, and the linkage rod 26 is fixedly connected to the moving block 16; the liquid guiding cylinder 24 is connected to the liquid storage tank 22 through a liquid inlet pipe 27, and the liquid guiding cylinder 24 is connected to the atomizing nozzle 23 through a liquid outlet pipe 28. A first one-way valve 29 is installed on the liquid inlet pipe 27, and a second one-way valve 30 is installed on the liquid outlet pipe 28;

[0054] The setting of the first one-way valve 29 enables the cleaning liquid inside the liquid storage tank 22 to enter the inside of the liquid guiding cylinder 24 through the liquid inlet pipe 27, and the cleaning liquid inside the liquid guiding cylinder 24 cannot enter the liquid storage tank 22 through the liquid inlet pipe 27; the setting of the second one-way valve 30 enables the cleaning liquid inside the liquid guiding cylinder 24 to enter the atomizing nozzle 23 through the liquid outlet pipe 28, and the medium in the atomizing nozzle 23 cannot enter the liquid guiding cylinder 24 through the liquid outlet pipe 28;

[0055] When the moving block 16 moves to the left, the piston 25 is driven by the linkage rod 26 to move synchronously to the left along the inner wall of the liquid guiding cylinder 24, and then the cleaning liquid is pumped from the inside of the liquid storage tank 22 through the liquid inlet pipe 27. After the glass lens 3 moves down, the moving block 16 is driven to move to the right and reset. During this process, the piston 25 is driven by the linkage rod 26 to move to the right along the inner wall of the liquid guiding cylinder 24, and the cleaning liquid inside the liquid guiding cylinder 24 is sprayed onto the surface of the glass lens 3 to be cleaned through the liquid outlet pipe 28 and the atomizing nozzle 23 in sequence.

[0056] The wiping assembly is connected to the second transmission shaft 14. The wiping assembly includes a fixed seat fixedly connected to the inner wall on one side of the housing 2, a third transmission shaft 31 rotatably connected inside the fixed seat along the width direction of the housing 2, a cleaning strip 32 fixedly sleeved outside the third transmission shaft 31, and a first bevel gear 33 fixedly sleeved outside the second transmission shaft 14. The friction between the third transmission shaft 31 and the fixed seat is relatively large, and the third transmission shaft 31 will not rotate without external force driving. A switch door is provided on one side of the housing 2 for replacing the cleaning strip 32 and replenishing the cleaning liquid into the liquid storage tank 22. The cleaning strip 32 is used for surface cleaning of the glass lens 3 inside the housing 2, and the cleaning strip 32 is located between the glass lens 3 and the atomizing nozzle 23. Two second bevel gears 34 are fixedly sleeved outside the third transmission shaft 31, and the first bevel gear 33 is located between the two second bevel gears 34. The first bevel gear 33 is a defective bevel gear. When the first bevel gear 33 rotates, it meshes with the two second bevel gears 34 in sequence, driving the third transmission shaft 31 to rotate in different directions.

[0057] During the rotation of the second transmission shaft 14, when driving the moving block 16 to move leftward to drive the two glass lenses 3 to exchange positions, the second transmission shaft 14 drives the first bevel gear 33 to rotate synchronously. Through the meshing of the first bevel gear 33 with the two second bevel gears 34 in sequence, the third transmission shaft 31 is driven to rotate reciprocally within a range of 40°, thereby driving the cleaning strip 32 to swing up and down reciprocally, so as not to block the dust suction nozzle 36 from absorbing the dust carried by the glass lens 3 when entering the housing 2.

[0058] When the second transmission shaft 14 rotates to drive the moving block 16 to move rightward to spray the cleaning liquid on the surface of the glass lens 3, it also drives the cleaning strip 32 to swing up and down reciprocally. During this process, the surface of the glass lens 3 is frictionally cleaned, and finally the cleaning strip 32 is reset to the front of the dust suction nozzle 36.

[0059] A dust collector 35 is installed inside the housing 2, and a dust suction nozzle 36 is installed at the input end of the dust collector 35. The dust suction nozzle 36 is located on the side of the glass lens 3 away from the cleaning strip 32.

[0060] By starting the dust collector 35, when the glass lenses 3 are exchanged, the dust entering the housing 2 can be absorbed, and the dust on the cleaning strip 32 can also be absorbed.

[0061] Working principle: When it is necessary to clean the glass lens 3 currently attached to the lens surface of the camera body 1, the motor 10 is controlled to drive the first gear 12 to rotate forward. Through the meshing effect between the first gear 12 and the first one-way gear 13, the first drive shaft 8 is driven to rotate, driving the first reciprocating screw 9 to rotate synchronously, driving the lifting block 4 to move upward from the bottom end of the first reciprocating screw 9 to its top end. During this process, the first transmission shaft 5, the connecting strip 6, and the two glass lenses 3 are driven to move upward synchronously, so that the glass lens 3 attached to the lens surface of the camera body 1 moves upward into the interior of the housing 2. The motor 10 is controlled to drive the first gear 12 to rotate reversely. Through the meshing effect between the first gear 12 and the second one-way gear 21, the worm 17 is driven to rotate. Through the meshing effect between the worm 17 and the worm gear 20, the second transmission shaft 14 is driven to rotate, and the second reciprocating screw 15 rotates accordingly, driving the moving block 16 to move from the right end of the second reciprocating screw 15 to its left end. During this process, the rack 18 is driven to move synchronously. Since the second gear 19 follows the lifting block 4 and moves upward to the lower side of the left side of the rack 18, when the rack 18 moves to the left, a meshing relationship is established with the second gear 19, driving the second gear 19 and the first transmission shaft 5 to rotate 180°, so as to exchange the positions of the two glass lenses 3 through the connecting strip 6. When the moving block 16 moves to the left, the piston 25 is driven to move leftward synchronously along the inner wall of the liquid guide cylinder 24 through the linkage rod 26, and then the cleaning liquid is extracted from the interior of the liquid storage tank 22 through the liquid inlet pipe 27. Then, the motor 10 is controlled to continue driving the first reciprocating screw 9 to rotate, driving the lifting block 4 to move downward from the top end of the first reciprocating screw 9 to its bottom end. During this process, the replaced glass lens 3 is driven to fit the lens surface of the camera body 1. Then, the motor 10 is controlled to drive the second transmission shaft 14 and the second reciprocating screw 15 to rotate, driving the moving block 16 to move rightward to reset. During this process, the piston 25 is driven to move rightward along the inner wall of the liquid guide cylinder 24 through the linkage rod 26, and the cleaning liquid inside the liquid guide cylinder 24 is sprayed onto the surface of the glass lens 3 to be cleaned in sequence through the liquid outlet pipe 28 and the atomizing nozzle 23. At the same time, the second transmission shaft 14 drives the first bevel gear 33 to rotate synchronously. Through the meshing effect of the first bevel gear 33 with the two second bevel gears 34 in sequence, the third transmission shaft 31 is driven to reciprocate within a range of 40°, thereby driving the cleaning strip 32 to swing up and down reciprocally, and cooperating with the cleaning liquid to perform frictional cleaning treatment on the surface of the glass lens 3.
