Description

Technical Field

[0001] The present invention relates to the field of cameras, and more specifically, to a high-definition security camera for community corridors. Background Art

[0002] To improve the security protection level of communities, most current communities will install surveillance cameras in corridors. At the same time, to expand the surveillance coverage of the cameras in community corridors and enhance the flexibility of surveillance, rotatable surveillance cameras are generally used in communities at present to improve the surveillance effect on community corridors.

[0003] The drive systems inside existing rotatable cameras can be mainly divided into gear drive and synchronous belt drive (i.e., transmitting kinetic energy through a conveyor belt). Among them, for cameras using a conveyor belt to transmit kinetic energy, it is easy for the conveyor belt to be contaminated by external dust, reducing the stability of the conveyor belt in transmitting kinetic energy to the camera. That is, it is easy for the camera to shake during the rotation operation. At the same time, after the conveyor belt is used for a long time, the tension of the conveyor belt is likely to gradually decrease due to factors such as its own material. When the tension of the conveyor belt gradually decreases, the stability of its transmission of kinetic energy to the camera will also decrease accordingly, easily causing the camera to shake during the rotation operation and reducing the surveillance effect of the camera on community corridors. Therefore, there is an urgent need to design a high-definition security camera for community corridors to solve the above problems. Summary of the Invention

[0050] 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.

[0051] Please refer to Figures 1 to 15 , a high-definition security camera for a residential corridor, including a bracket 1 and a conveyor belt 4. The lower end of the bracket 1 is fixedly installed with a housing 2. A transmission component 3 is arranged in the housing 2, and an adjustment component 5 is arranged in the housing 2.

[0052] As Figure 1 - Figure 3 , Figure 14 shown in

[0053] , the transmission component 3 includes a support plate 31 fixedly installed on the inner side wall of the housing 2. A servo motor 32 is fixedly installed at the upper end of the support plate 31. A rotating shaft 33 is fixedly installed at the driving end of the servo motor 32. A rotating rod 34 is rotatably installed on the inner top wall of the housing 2. Rotating wheels 35 are fixedly installed on both the rotating shaft 33 and the rotating rod 34, and the conveyor belt 4 is sleeved and installed between the two rotating wheels 35. An air delivery component 6 is arranged on the rotating shaft 33.

[0054] A vibration isolation ring 9 is fixedly installed at the lower end of the rotating rod 34. A camera main body 10 is fixedly installed on the vibration isolation ring 9. A limiting component is jointly installed between the camera main body 10 and the housing 2.

[0055] When it is necessary to use this device to monitor the residential corridor, start the servo motor 32 and the camera main body 10. When the servo motor 32 operates to drive the rotating shaft 33 to rotate reciprocally, through the cooperation of the two rotating wheels 35 and the conveyor belt 4, it drives the rotating rod 34 to drive the camera main body 10 to rotate reciprocally to conduct an all-round monitoring of the residential corridor, which can help improve the monitoring effect of the camera main body 10 on the residential corridor. Figure 2 - Figure 4 , Figure 8 , Figure 9 , Figure 15 shown in

[0056] The cleaning assembly 7 includes rotating shafts 71 respectively rotatably installed at the lower ends of two vibration isolation pads 53. Fixed boxes 73 are rotatably installed on both of the two rotating shafts 71. Cleaning rollers 74 are fixedly installed on both of the two rotating shafts 71. A scraping component is commonly installed between the two fixed boxes 73.

[0057] The scraping component includes rotating gears one 56 respectively fixedly installed on two round rods 54. Rotating gears two 72 meshing with the corresponding rotating gears one 56 are fixedly installed on both of the two rotating shafts 71 (when the corresponding rotating gear one 56 and the rotating gear two 72 are in long-term cooperative transmission and mechanical wear occurs, resulting in vibration when the corresponding round rod 54 transmits kinetic energy to the rotating shaft 71, at this time, the corresponding vibration isolation pad 53 can absorb and disperse the vibration force of this part, thereby effectively preventing the rotating shaft 71 from transmitting the vibration force of this part to the conveyor belt 4 through the corresponding cleaning roller 74, and the round rod 54 from transmitting the vibration force of this part to the conveyor belt 4 through the corresponding friction roller 55, reducing the stability of the conveyor belt 4 in transmitting kinetic energy to the camera body 10). Scrapers 75 are fixedly installed on the inner walls of both of the two fixed boxes 73. A plurality of air spraying pipes 76 are hermetically penetrated and fixedly installed on both of the two scrapers 75;

[0058] Collection boxes one 77 are fixedly installed on the inner bottom walls of both of the two fixed boxes 73, and there are two collection boxes one 77. Collection boxes two 78 are fixedly installed on the inner bottom walls of both of the two fixed boxes 73.

[0059] During the operation of the camera body 10 and the internal components of the machine shell 2, heat will be generated. To timely dissipate this part of heat and prevent the accumulation of this part of heat, which may damage the internal components of the machine shell 2 and the electronic components inside the camera body 10, multiple heat dissipation holes are usually opened above the housing of the existing monitoring device (such as the multiple exhaust holes 16 opened above the machine shell 2). However, during the process of dissipating heat from the internal components of the monitoring device through the multiple heat dissipation holes, dust and other impurities in the external gas will also enter the device internal, that is, inside the machine shell 2, and contaminate the conveyor belt 4 inside the machine shell 2;

[0060] Normally, the friction force between the conveyor belt 4 and the two rotating wheels 35 is relatively stable. At this time, through the cooperation of the rotating shaft 33, the two rotating wheels 35 and the conveyor belt 4, stable kinetic energy can be transmitted to the rotating rod 34, so that the rotating rod 34 drives the camera body 10 to rotate reciprocally stably. However, when the impurities on the inner side wall of the conveyor belt 4 gradually increase, when the part of the inner side wall of the conveyor belt 4 (that is, the side where the two cleaning rollers 74 are in contact with the conveyor belt 4) with more adhered impurities contacts the rotating wheel 35 on the rotating rod 34, the friction force between this part of the conveyor belt 4 and this rotating wheel 35 will instantaneously increase, causing an instantaneous change in the rotation speed of the rotating rod 34, which is likely to cause the rotating rod 34 to shake, reducing the monitoring effect of the rotating rod 34 driving the camera body 10 to rotate on the community corridor.

[0061] When the servo motor 32 operates and transmits kinetic energy to the rotating rod 34 through the rotating shaft 33, the two rotating wheels 35 and the conveyor belt 4, at this time, through the cooperation of the two cleaning rollers 74, the inner side wall of the conveyor belt 4 can be cleaned, which helps to improve the stability of the conveyor belt 4 continuously transmitting kinetic energy to the rotating rod 34 and the camera body 10.

[0062] Since in the initial state, the self-tension of the conveyor belt 4 is in a normal state. When the conveyor belt 4 is stressed and drives the friction pad 51 to rotate together, the large frictional force generated between the friction pad 51 and the two friction rollers 55 will drive the two friction rollers 55 to rotate. During the process that the two friction rollers 55 drive the corresponding round rods 54 to rotate, through the cooperation of the corresponding first rotating gear 56 and the second rotating gear 72, the two rotating shafts 71 and the two cleaning rollers 74 will rotate together to further clean the inner side wall of the conveyor belt 4, which helps to improve the cleaning effect of the two cleaning rollers 74 on the inner side wall of the conveyor belt 4.

[0063] The two cleaning rollers 74 are specifically made of sponge material. When the two cleaning rollers 74 cooperate to clean the inner side wall of the conveyor belt 4, through the softness of its own sponge material, while effectively cleaning the inner side wall of the conveyor belt 4, the wear of the two cleaning rollers 74 on the inner side wall of the conveyor belt 4 can also be reduced. At the same time, through the two continuously rotating cleaning rollers 74 under force, the contact surface between the two cleaning rollers 74 and the inner side wall surface of the conveyor belt 4 can be continuously updated, which helps to improve the cleaning effect of the two cleaning rollers 74 on the inner side wall of the conveyor belt 4.

[0064] At the same time, during the process that the two cleaning rollers 74 rotate to clean the inner side wall of the conveyor belt 4, some impurities on the inner side wall of the conveyor belt 4 will adhere to the surfaces of the two cleaning rollers 74. At this time, through the two scraping plates 75, the larger impurities adhered to the surfaces of the corresponding cleaning rollers 74 can be scraped off, which helps to improve the effect of the two cleaning rollers 74 continuously wiping and adsorbing the surface impurities of the inner side wall of the conveyor belt 4.

[0065] As Figure 9 shown in the direction, collection boxes 77 are provided on both the left and right sides of the cleaning roller 74 (the collection box 77 on the right side of the cleaning roller 74 is blocked and not shown, and the purpose of setting the two collection boxes 77 is to adapt to the intermittent driving of the conveyor belt 4 to drive the cleaning roller 74 to rotate reciprocally. When the corresponding scraping plate 75 scrapes off the impurities on the surface of the cleaning roller 74, the corresponding collection box 77 has the collection effect on the impurities). When the two scraping plates 75 scrape off the larger impurities adhered to the surfaces of the corresponding cleaning rollers 74, through the cooperation of the corresponding two collection boxes 77 and the collection box 78, the collection of this part of the impurities can be realized.

[0066] The friction pad 51 and the two friction rollers 55 can specifically be made of polyurethane material. Due to the good wear resistance, relatively high friction coefficient, and long service life of polyurethane itself, it can help improve the effect of driving the two friction rollers 55 to rotate by themselves continuously through the frictional force between the friction pad 51 and the two friction rollers 55 during the rotation of the friction pad 51.

[0067] As Figure 3 - Figure 9 shown, the air delivery assembly 6 includes a wind collecting box 61 rotatably installed on the rotating shaft 33. A fan 62 is fixedly installed on the rotating shaft 33. A one-way air suction pipe 63 is fixedly connected to the lower end of the wind collecting box 61. There are two one-way air suction pipes 63, and one ends of the two one-way air suction pipes 63 are hermetically penetrated and fixedly installed on the machine shell 2. Filter elements 64 are fixedly installed on the inner walls of the two one-way air suction pipes 63;

[0068] A positioning plate 66 is fixedly installed on the inner top wall of the machine shell 2. A buffer box 67 is fixedly installed on the positioning plate 66. A one-way exhaust pipe 65 is fixedly connected between the buffer box 67 and the wind collecting box 61. An exhaust pipe 68 is fixedly connected to the buffer box 67. An air delivery component is jointly installed between the exhaust pipe 68 and the two fixed boxes 73. A push-pull component is jointly installed between the side round rod 54 and the exhaust pipe 68.

[0069] The air delivery component includes an air delivery pipe 69 fixedly connected to the exhaust pipe 68. A rubber conduit 610 is fixedly connected to the air delivery pipe 69. There are two rubber conduits 610, and one ends of the two rubber conduits 610 are hermetically penetrated and fixedly installed on the corresponding fixed boxes 73.

[0070] The push-pull component includes a fixing plate 611 fixedly installed on the buffer box 67. Two first spring telescopic rods 612 are fixedly installed on the fixing plate 611. A push plate 613 is jointly fixedly installed between the two first spring telescopic rods 612. A connecting rod 614 is fixedly installed on the side wall of the push plate 613, and the connecting rod 614 penetrates and is slidably installed in the exhaust pipe 68;

[0071] A sealing slider 615 (i.e., as Figure 7 shown, in the initial state, the sealing slider 615 blocks the lower end of the air delivery pipe 69) that cooperates with the air delivery pipe 69 is fixedly installed on the connecting rod 614, and the sealing slider 615 is hermetically and slidably installed in the exhaust pipe 68. A cam 616 that cooperates with the push plate 613 is fixedly installed at the lower end of the side round rod 54.

[0072] When the rotating shaft 33 is driven by force to drive the camera body 10 to rotate reciprocally to monitor the corridor of the community, it will drive the fan 62 to rotate together. The suction force generated by the rotation of the fan 62 will suck the external gas into the air collecting box 61 through the two one-way air suction pipes 63, and input this part of the gas into the buffer box 67 through the one-way exhaust pipe 65.

[0073] Through the setting of the two filters 64, the cleanliness of the gas entering the air collecting box 61 through the two one-way air suction pipes 63 can be effectively improved, which helps to improve the cleaning effect of the subsequent use of this part of the gas on the surfaces of the two cleaning rollers 74.

[0074] When the friction pad 51 is driven by force to rotate and drive the friction roller 55 and the round rod 54 at the lower left to rotate self - rotatably (as Figure 4 shown in the direction), the cam 616 will rotate together. During the rotation of the cam 616, through the cooperation with the two spring telescopic rods one 612, it can drive the push plate 613 to drive the connecting rod 614 and the sealing slider 615 to move reciprocally left and right (as Figure 7 shown in the direction). When the sealing slider 615 moves to the right and gradually moves away from the lower end of the air delivery pipe 69, the gas collected in the buffer box 67 at this time will enter the two rubber conduits 610 along the air delivery pipe 69 and be ejected from the two rubber conduits 610, blowing off the smaller impurities adhering to the surfaces of the corresponding cleaning rollers 74. This can help to further improve the cleaning effect of the equipment on the two cleaning rollers 74 and help to further improve the cleaning effect of the two cleaning rollers 74 on the inner side wall of the conveyor belt 4 continuously.

[0075] At the same time, by driving the sealing slider 615 to intermittently block the lower end of the air delivery pipe 69 through the push - pull component, the intermittent buffering of the gas in the buffer box 67 can be realized, which can help to improve the intensity of the intermittent input of the gas from the air delivery pipe 69 into the two rubber conduits 610, that is, it helps to improve the cleaning effect of this part of the gas on the two cleaning rollers 74.

[0076] From Figure 9 it can be seen that two covers are installed on the upper ends of the two collection boxes two 78. When the rubber conduit 610 blows air to clean the surface of the corresponding cleaning roller 74 from top to bottom, the blown - off impurities will, under the action of their own gravity, fall into the corresponding collection box two 78 along the gap between the corresponding two covers. At this time, through the two covers, the risk of the impurities collected in the collection box two 78 being blown up again by the wind can be effectively reduced, which helps to reduce the situation that this part of the impurities pollute the surface of the cleaning roller 74 again, that is, it helps to ensure the cleaning effect of the two rubber conduits 610 blowing air on the surface of the corresponding cleaning roller 74.

[0077] At the same time, since the scraping plate 75 is fixedly and hermetically connected to the upper, lower, left and right sides of the inner wall of the corresponding fixed box 73 (as Figure 8in the shown direction), and both scraping plates 75 are in contact with the surfaces of the corresponding cleaning rollers 74. Therefore, on the right rear side of the scraping plate 75 (as Figure 9 shown in the direction), it is in a nearly sealed state. That is, most of the gas input into the fixed box 73 through the corresponding rubber conduit 610 will gather on the right rear side of the scraping plate 75;

[0078] When the gas on the right rear side of the scraping plate 75 gradually increases, this part of the gas will eventually be sprayed onto the inner wall of the conveyor belt 4 through the corresponding multiple air spray pipes 76, so as to further clean the inner wall of the conveyor belt 4, which helps to further improve the cleaning effect of the equipment on the inner wall of the conveyor belt 4, that is, to further ensure the stability of the conveyor belt 4 continuously transmitting kinetic energy to the camera body 10.

[0079] The right ends of the multiple air spray pipes 76 (as Figure 9 shown in the direction) are all installed with filter meshes (not shown in the figure). The filter meshes can effectively intercept the impurities contained in the flowing gas on the right rear side of the scraping plate 75, which helps to improve the cleaning effect of the multiple air spray pipes 76 cooperating to blow the inner wall of the conveyor belt 4.

[0080] As Figure 10 - Figure 13 shown, the driving component 8 includes a shaft rod 84 rotatably installed in the limiting groove 14, and a winding mechanism is installed on the shaft rod 84.

[0081] The winding mechanism includes winding rollers 85 fixedly installed on the shaft rod 84. There are two winding rollers 85. Steel wire ropes 86 are wound and installed on both winding rollers 85, and one ends of the two steel wire ropes 86 are fixedly connected to the corresponding sliding blocks 52. A transmission component is jointly installed between the shaft rod 84 and the buffer box 67.

[0082] The transmission component includes a second spring telescopic rod 81 fixedly installed on the inner side wall of the buffer box 67. One end of the second spring telescopic rod 81 is fixedly installed with a sealing sliding plate 82, and the sealing sliding plate 82 is hermetically slidably installed in the buffer box 67. A rack bar 83 is fixedly installed on the upper end of the sealing sliding plate 82. A sliding port 87 matching the rack bar 83 is opened on the buffer box 67;

[0083] A groove 812 communicating with the sliding port 87 is opened on the buffer box 67. A plugging plate 811 is fixedly installed at the lower end of the rack bar 83, and the plugging plate 811 is hermetically slidably installed on the groove 812. A groove is opened on the buffer box 67, and rod bodies evenly distributed in a ring shape are slidably installed on the groove. A toothed ring 88 is jointly fixedly installed between the rod bodies. A spring pushing member 89 is installed on the toothed ring 88. A plurality of clamping grooves 810 evenly distributed in a ring shape are opened on the shaft rod 84.

[0084] The conveyor belt 4 for transmitting kinetic energy is usually made of elastic materials such as rubber and polyurethane. When the conveyor belt 4 is in a tensioned state for a long time, the molecular chain structure inside it will be stretched or deformed, resulting in an increase in the overall length of the conveyor belt 4 and a gradual decrease in its own tension force.

[0085] As the tension force of the conveyor belt 4 decreases, the frictional force between the conveyor belt 4 and the two rotating wheels 35 will also decrease accordingly. When the self-tension force of the conveyor belt 4 is in a normal state, the conveyor belt 4 can stably transmit the kinetic energy output by the rotating shaft 33 to the rotating rod 34, enabling the rotating rod 34 to drive the camera body 10 to rotate reciprocally stably. However, when the tension force of the conveyor belt 4 decreases and the frictional force between the conveyor belt 4 and the two rotating wheels 35 decreases, when the conveyor belt 4 is subjected to force and rotates between the two rotating wheels 35, local slipping is likely to occur, resulting in an instantaneous deceleration or acceleration of the rotating rod 34. This irregular speed change is likely to cause jitter during the rotation of the rotating rod 34 driving the camera body 10, reducing the monitoring effect of the device.

[0086] When the tension force of the conveyor belt 4 is in a normal state, the self-tension of the conveyor belt 4 will exert a certain pressure on the friction pad 51. This pressure will cause sufficient normal pressure to be generated between the friction pad 51 and the two friction rollers 55, so that sufficient frictional force can be generated when the three move relative to each other, driving the two friction rollers 55 to rotate. However, when the tension force of the conveyor belt 4 decreases and the conveyor belt 4 becomes slack and the pressure on the friction pad 51 decreases, the normal pressure between the friction pad 51 and the two friction rollers 55 will also decrease accordingly, and the frictional force between the three will also decrease. When the tension force of the conveyor belt 4 gradually decreases and the frictional force between the friction pad 51 and the two friction rollers 55 decreases to a certain extent, when the friction pad 51 is subjected to force and rotates, it cannot overcome the static frictional force of the friction roller 55 and the resistance moment during rotation, so it cannot drive the friction roller 55 to rotate.

[0087] When the rotating shaft 33 continuously drives the conveyor belt 4 and the friction pad 51 to rotate, while the friction roller 55 cannot rotate and the sealing slider 615 is not driven by an external force and continuously blocks the lower end of the air delivery pipe 69, at this time, the rotating shaft 33 drives the fan 62 to continuously rotate and suck air, which will cause the gas volume inside the buffer box 67 to gradually increase. When the pressing force exerted by the buffered gas inside the buffer box 67 on the sealing slide plate 82 is greater than the self-elastic force of the spring telescopic rod II 81, at this time, the gas will press the sealing slide plate 82 to move upward (as Figure 10 shown in the direction);

[0088] When the sealing slide plate 82 is driven by force to continuously move upward (as Figure 12In the shown direction), it will drive the gear ring 88 to drive the spring pusher 89 to rotate clockwise. During this process, through the thrust exerted by the spring pusher 89 on the corresponding card slot 810, the shaft rod 84 can rotate clockwise accordingly. When the shaft rod 84 drives the two winding rollers 85 to rotate clockwise and wind the corresponding steel wire ropes 86, it will pull the two sliding blocks 52, the two vibration isolation pads 53, and the two friction rollers 55 closer to each other. The two friction rollers 55 approach each other, and the continuous pulling force applied to the front and rear sides of the conveyor belt 4 (as Figure 4 In the shown direction) can prompt the originally loose conveyor belt 4 to become taut again, thereby realizing the automatic adjustment of the tension of the conveyor belt 4.

[0089] When the tension of the conveyor belt 4 is adjusted to the normal state, at this time, the rotation of the conveyor belt 4 will, through the cooperation of the friction pad 51 and the push-pull component, drive the sealing slider 615 to continuously and intermittently move away from the lower end of the air delivery pipe 69, so that the gas cached inside the buffer tank 67 flows into the air delivery pipe 69 intermittently, thereby realizing the pressure relief effect inside the buffer tank 67;

[0090] When the gas volume inside the buffer tank 67 decreases and the pressing force exerted by the gas on the sealing slide plate 82 is less than the self-elastic force of the spring telescopic rod II 81, at this time, through the self-elastic force of the spring telescopic rod II 81, it can drive the sealing slide plate 82 to drive the rack bar 83 to move downward and reset (as Figure 12 In the shown direction). When the rack bar 83 moves downward and drives the gear ring 88 and the spring pusher 89 to rotate counterclockwise, at this time, the resistance exerted by the multiple card slots 810 on the spring pusher 89 will drive the spring pusher 89 to rotate reciprocally, that is, at this time, the spring pusher 89 cannot drive the shaft rod 84 to rotate, thereby ensuring the effect of the shaft rod 84 rotating to drive the two friction rollers 55 to approach each other and adjust the tension of the conveyor belt 4.

[0091] At the same time, when the tension of the conveyor belt 4 is in the normal state and the friction force between the friction pad 51 and the two friction rollers 55 decreases due to their long-term cooperation, at this time, through the cooperation of the air delivery component 6 and the winding mechanism, driving the two friction rollers 55 to approach each other can increase the pressing force of the two friction rollers 55 on the friction pad 51, thereby helping to increase the friction force between the two friction rollers 55 and the friction pad 51 and helping to improve the use effect of the continuous cooperation between the two friction rollers 55 and the friction pad 51.

[0092] At the same time, when the sealing slide plate 82 drives the rack bar 83 to move upward or downward (as Figure 13 In the shown direction), the blocking plate 811 will move together accordingly. At this time, through the blocking plate 811, the blocking of the sliding port 87 can be realized, avoiding the gas cached inside the buffer tank 67 from escaping from the sliding port 87.

[0093] Such as Figure 14 、Figure 15 As shown in the figure, the limiting component includes an annular sliding groove 15 formed in the casing 2. A fixed ring 11 is hermetically and rotatably installed on the annular sliding groove 15. Shock-absorbing air bags 12 are fixedly installed on the camera body 10 and are evenly distributed in a ring shape. The fixed ring 11 is hermetically penetrated and fixedly installed with roller members 13 that are evenly distributed in a ring shape. The roller members 13 are all slidably installed on the annular sliding groove 15, and the roller members 13 are all fixedly connected to the corresponding shock-absorbing air bags 12. The casing 2 is provided with a plurality of exhaust holes 16.

[0094] When the tension of the conveyor belt 4 decreases and the two friction rollers 55 do not adjust the tension of the conveyor belt 4, the conveyor belt 4 transmits unstable kinetic energy to the rotating rod 34, causing the rotating rod 34 to be subjected to tangential vibration. At this time, the vibration isolation ring 9 can absorb and disperse this part of the vibration energy, thereby reducing the vibration intensity received by the camera body 10. That is, it helps to reduce the amplitude of the camera body 10 when the tension of the conveyor belt 4 decreases and the rotating rod 34 jitters, and helps to ensure the monitoring effect of the camera body 10 rotating and running on the community corridor.

[0095] The vibration isolation ring 9 is specifically made of polyurethane material. The polyurethane material has high strength and elasticity, and its internal structure is usually a porous foam. When the tension of the conveyor belt 4 decreases and the rotating rod 34 jitters, the internal pores of the vibration isolation ring 9 will undergo elastic deformation, which can effectively disperse and absorb this part of the vibration energy.

[0096] At the same time, during the process of the rotating rod 34 driving the camera body 10 to reciprocate and rotate through the vibration isolation ring 9, the cooperation of the plurality of shock-absorbing air bags 12, the plurality of roller members 13, the fixed ring 11 and the annular sliding groove 15 can help improve the stability of the camera body 10 during the reciprocating rotation process, and help improve the overall quality of the monitoring picture during the reciprocating rotation of the camera body 10.

[0097] At the same time, if the camera body 10 is interfered by a large airflow on one side during operation, the impact force generated by the airflow on this side is likely to cause the camera body 10 to vibrate in the radial direction of the rotating rod 34, causing the camera body 10 to shake left and right or back and forth under force (as Figure 14 shown in the direction), at this time, through a plurality of shock-absorbing air bags 12 that can be compressed and stretched, the vibration energy of the camera body 10 can be absorbed, which can help further ensure the stability of the camera body 10 during the rotating operation process.

[0098] A plurality of shock-absorbing air bags 12 are made of elastic materials such as silicone rubber or polyurethane. An appropriate amount of gas is filled inside each of the plurality of shock-absorbing air bags 12. When the camera body 10 is subjected to a tangential vibration force and reciprocally compresses and stretches the plurality of shock-absorbing air bags 12, the gas inside the plurality of shock-absorbing air bags 12 will be reciprocally compressed and expanded under the force. During this process, the vibration energy of the camera body 10 can be effectively absorbed, which helps to improve the stability of the camera body 10 for monitoring the community corridor.

[0099] Usage method: When it is necessary to use this device to monitor the community corridor, by starting the servo motor 32 and the camera body 10, the camera body 10 can rotate reciprocally to conduct a full-range detection of the community corridor. At the same time, in the initial state, the tension of the conveyor belt 4 is in a normal state. When the conveyor belt 4 rotates stably to transfer kinetic energy to the camera body 10 and drives the friction pad 51 to rotate together, at this time, due to the large frictional force between the friction pad 51 and the two friction rollers 55, the two friction rollers 55 can drive the two cleaning rollers 74 to rotate to clean the inner side wall of the conveyor belt 4, which helps to improve the cleanliness of the surface of the conveyor belt 4 after continuous use and helps to reduce the situation that the camera body 10 shakes during the rotation operation due to the dust attached to the inner side wall of the conveyor belt 4.

[0100] At the same time, during the rotation of the two cleaning rollers 74 under force, through the cooperation of the scraping component and the two scraping plates 75, the two cleaning rollers 74 can be automatically cleaned, which helps to improve the cleaning effect of the two cleaning rollers 74 on the inner side wall of the conveyor belt 4 continuously. At the same time, the gas ejected from the air supply component 6 and the two rubber ducts 610 can further improve the cleaning effect of the device on the two cleaning rollers 74, and the air flow ejected from the air supply component 6 and the plurality of air ducts 76 to the inner side wall of the conveyor belt 4 can further improve the cleaning effect of the device on the inner side wall of the conveyor belt 4.

[0101] When the tension of the conveyor belt 4 gradually decreases due to long-term use or other factors, at this time, through the cooperation of the air supply component 6 and the winding mechanism, the drive shaft 84 can be rotated to wind the two steel wires 86. During the winding process of the two steel wires 86, the pulling force generated on the two sliding blocks 52 can make the two friction rollers 55 approach each other and apply a pulling force to the front and rear sides of the conveyor belt 4 (as Figure 4 shown in the direction) until the tension of the conveyor belt 4 returns to the normal state, so as to realize the automatic adjustment of the tension of the conveyor belt 4, which helps to improve the stability of the conveyor belt 4 to continuously transfer kinetic energy to the camera body 10, that is, it helps to further improve the monitoring effect of the camera body 10 during continuous operation on the community corridor.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
