Description

Technical Field

[0001] This invention relates to the field of camera technology, and specifically to a building security monitoring camera that is easy to maintain. Background Technology

[0002] The easy-to-maintain building security monitoring camera is a security device optimized to address the cumbersome maintenance issues of traditional cameras. It adopts modular components, quick-disassembly structure and external maintenance interface, which can realize the quick disassembly and maintenance of components such as lens, motor, and reduction mechanism, greatly shortening the maintenance time and ensuring the continuous and stable operation of the building monitoring system.

[0003] While traditional cameras are easy to maintain, in actual use, they are often affected by their installation environment. For example, they may be near roads, ventilation openings, or in dusty industrial areas. These locations can easily cause dust to accumulate on the camera surface. Once dust adheres to the lens surface, it gradually reduces light transmittance, resulting in blurry images and loss of detail. This directly affects the clarity and recognition effect of the surveillance images. Long-term accumulated dust may also seep into the gaps in the equipment, affecting the operation of internal components and even shortening the camera's lifespan. This problem not only increases the frequency of manual cleaning and maintenance costs, but also reduces the actual performance and long-term reliability of the camera. As a result, the camera, which was originally easy to maintain, still requires frequent maintenance in harsh environments. Summary of the Invention

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0019] The present invention will be further described below with reference to embodiments.

[0020] See attached document Figure 1-10A building security monitoring camera that is easy to maintain includes: a camera body 1 and a mounting base 2. The mounting base 2 is used to enable rotation monitoring and fixation of the camera body 1. The camera body 1 is rotatably connected to the top of the mounting base 2. A drive source is fixedly connected inside the mounting base 2. The drive source is existing technology and can be a motor. The specific selection can be made according to its usage environment and power consumption. The drive source is fixedly connected to a reducer through a transmission rod, and the reducer is fixedly connected to the camera body 1. The camera also includes: an air collection and cleaning mechanism 3 for self-cleaning. The air collection and cleaning mechanism 3 includes two sets of ratchet wheels 301, and the ratchet teeth of the two sets of ratchet wheels 301 are symmetrically arranged. Pads 302 are engaged on the outer sides of both sets of ratchet wheels 301. A transmission ring 303 is rotatably connected to the outer side of the pawls 302. Furthermore, the pawl 302 is elastically connected to the transmission ring 303 via a spring of existing technology to ensure the normal use of the pawl 302. Three sets of push rings 304 are fixedly connected to the outside of the transmission ring 303. A rotating ring 305 is elastically connected to one side of the three sets of push rings 304 via a compression spring. Three sets of compression plates 306 are fixedly connected to the outside of the rotating ring 305. A moving plate 307 is elastically connected to one side of the compression plate 306 via a reset spring. The moving plate 307 is slidably connected to the rotating ring 305. A movable positioning component 308 is provided on one side of the moving plate 307. A sealing ring 309 is slidably connected to one side of the moving plate 307. The sealing ring 309 is slidably connected to the compression plate 306. An air inlet groove is provided on the outside of the sealing ring 309. A jet cleaning component 310 is provided on one side of the sealing ring 309. The camera body 1 is rotatably connected to the top of the mounting base 2. The drive source drives the camera body 1 through a transmission rod and a reducer, which not only meets the needs of all-round building monitoring, but also allows the speed to be adjusted by the reducer to ensure smooth rotation of the camera body 1 and avoid affecting the clarity of the monitoring image due to excessive speed. The air collection and cleaning mechanism 3 is the core cleaning component. Its two sets of symmetrically arranged ratchet wheels 301 and pawls 302 mesh with each other. With the elasticity of the spring, they can drive the transmission rings 303 to move stably when the camera body 1 rotates. The three sets of push rings 304 on the outside of the transmission rings 303 transmit power to the rotating rings 305 through compression springs. The movable positioning component 308 accurately positions the rotating rings 305, push rings 304 and moving plates 307. When the compression spring is compressed to a set degree by the push rings 304, it will push the rotating rings 305 to move. The rotating rings 305 then drive the three sets of compression plates 306 to move. The compression plates 306 move through the compound The positioning spring cooperates with the moving plate 307 to squeeze and discharge the gas between them. At the same time, the movable positioning component 308 can unlock the positioning of the moving plate 307 through the squeezing plate 306, realizing the flexible switching positioning of the moving plate 307. The sealing ring 309 is slidably connected to the moving plate 307 and the squeezing plate 306 and has an air inlet groove. The air inlet groove can efficiently introduce external gas. The jet cleaning component 310 converts the introduced gas into cleaning power to complete the automatic cleaning of the lens. This structure not only retains the original advantage of the camera body 1 being easy to maintain, but also solves the pain point of the traditional camera body 1 being prone to dust accumulation through the air collection and cleaning mechanism 3. It not only avoids the problem of blurry images and loss of detail caused by dust adhering to the lens, but also prevents dust from seeping into the equipment gaps and damaging the internal components, extending the service life of the camera body 1. At the same time, it greatly reduces the frequency of manual cleaning and maintenance costs, further ensuring the long-term stable operation of the building monitoring system and improving the clarity and recognition effect of the monitoring images. See attached document Figure 1-3The movable positioning component 308 includes six sets of stops 3081, which are slidably connected to the sealing ring 309 and elastically connected to the sealing ring 309 via springs. An inclined block 3082 is fixedly connected to one side of each of the six sets of stops 3081, and a pressing block 3083 is provided on one side of the inclined block 3082. The pressing block 3083 is fixedly connected to the pushing ring 304 and the pressing plate 306 respectively. It is worth noting that the six sets of stops 3081 are structurally identical and are divided into two symmetrical functional units. The first set of three stops 3081 is used to position the moving plate 308. One side of 07 is limited, and the three blocks 3081 of the second group are used to limit the extrusion plate 306, but the structure of the inclined block 3082 fixed thereon is different. When the pushing ring 304 or the extrusion plate 306 moves to a specific position, the extrusion block 3083 fixed thereon will contact and squeeze the inclined block 3082 on the corresponding block 3081. This inclined surface action forces the block 3081 to retract radially along the sealing ring 309, thereby releasing the lock on the moving plate 307 or the extrusion plate 306, so that it can move to the next predetermined position under the drive of the return spring, realizing periodic and alternating positioning and unlocking actions. In this design, the six sets of stops 3081 of the active positioning component 308 are slidably connected to the sealing ring 309 and elastically connected by springs. The elastic force of the springs can drive the stops 3081 to automatically reset, ensuring that the stops 3081 and the sealing ring 309 are always tightly fitted, guaranteeing the sealing and stability of the positioning process. The inclined block 3082 on one side of the stops 3081 is linked with the push ring 304 and the pressing block 3083 on the pressing plate 306. When the push ring 304 moves to the designated position, the pressing block 3083 will press the inclined block 3082, causing the stops 3081 to extend and retract flexibly, thereby releasing the restriction on the pressing plate 306 and allowing the rotating ring 305 to rotate smoothly. At this time, the pressing spring on the pressing plate 306 will push the rotating ring 305. The gas compression action is completed; when the compression plate 306 moves to the side of the moving plate 307, the compression block 3083 connected to it will push the tilting block 3082 again, completely releasing the limiting constraint of the moving plate 307. The moving plate 307 can then move precisely to another set of stops 3081 under the action of the return spring, realizing the position switching. This structural design makes the positioning and unlocking actions smooth and avoids jamming or positioning deviation, ensuring that the gas compression and moving plate 307 switching actions in the gas collection and cleaning mechanism 3 are carried out in an orderly manner, further ensuring the stable and efficient operation of the automatic cleaning function. It is worth noting that each action is only a position switch between the compression plate 306 and the moving plate 307, and it can still effectively draw in gas and cycle. The air inlet groove is connected to an air inlet ring 4, which is fixedly connected to the mounting base 2. A filter plate 5 is fixedly connected to the outside of the air inlet ring 4, and a scraper 6 is provided on the outside of the filter plate 5. The air inlet ring 4 is fixed to the mounting base 2 to ensure the structural stability of the gas inlet channel. It is connected to the air inlet groove and can smoothly and efficiently introduce external gas into the sealing ring 309. The filter plate 5 on the outside of the air inlet ring 4 can effectively filter dust and impurities in the air, preventing these pollutants from entering the equipment and clogging the air passage, or causing wear to internal components such as the sealing ring 309 and the air collecting column 3101, thus ensuring the smooth flow of gas. The filter plate 5 ensures smooth operation and extends the service life of related components. The scraper 6 on the outside of the filter plate 5 can clean the dust adhering to the surface of the filter plate 5 in time, prevent the filter plate 5 from accumulating dust and clogging, and ensure that the air intake efficiency is not affected. This allows for a continuous supply of sufficient gas to the air collection and cleaning mechanism 3, ensuring stable and effective cleaning and avoiding the problem of incomplete cleaning due to insufficient air supply. At the same time, the filtering effect of the filter plate 5 reduces equipment failures caused by impurities, allowing the camera body 1 to operate stably in harsh environments with a lot of dust, further improving the overall reliability of the equipment and laying the foundation for the stable performance of subsequent cleaning and monitoring functions. See attached document Figure 1-9 The jet cleaning assembly 310 includes an air collecting column 3101, which is connected to a sealing ring 309 via a one-way valve. The air collecting column 3101 is fixedly connected to the interior of the camera body 1. One end of the air collecting column 3101 is connected to a cleaning nozzle 3102, which is fixedly connected to the top of the camera body 1. A connecting moving assembly 3103 is provided on the outer side of the cleaning nozzle 3102, and two sets of cleaning plates 3104 are provided on the outer side of the cleaning nozzle 3102. A support column 3105 is rotatably connected to one side of the camera body 1, and the support column 3105 is fixedly connected to the camera body 1. A rotary joint 3106 is rotatably connected to the top of the support column 3105, and the rotary joint 3106 is connected to the air collection column 3101 through a hose, and the rotary joint 3106 is connected to the cleaning plate 3104 through a pipe. Several sets of brush rings 3107 are provided on the outer side of the cleaning plate 3104, and a dust removal nozzle 3108 is connected to the outer side of the cleaning plate 3104. The cleaning plate 3104 is fixedly connected to the scraper 6. The air collection column 3101 of the jet cleaning assembly 310 is fixed inside the camera body 1 and connected to the sealing ring 309 through a one-way valve. The one-way valve effectively prevents gas backflow and ensures stable unidirectional gas delivery to the air collection column 3101, ensuring structural stability without affecting the normal monitoring function of the camera body 1. The support column 3105 is fixed on the camera body 1, providing reliable rotational support for the two sets of cleaning plates 3104. The rotary joint 3106 is connected to the air collection column 3101 through a hose, and then the gas is delivered to the cleaning plate 3104 through a pipeline, realizing flexible gas transmission. During the cleaning process, the dust removal nozzle 3108 first sprays gas to blow away the floating dust on the lens surface and the dust that is subsequently wiped off. At the same time, several sets of brush rings 3107 on the outside of the cleaning plate 3104 perform physical wiping to remove stubborn stains. The left and right movements differ, and the connection structure, influenced by the transmission force, causes the cleaning plate 3104 to move left and right. The cleaning plate 3104 can perform cleaning in both directions, and the brush ring 3107 and dust removal nozzle 3108 on the rear side can perform a secondary cleaning of the cleaned mirror surface, further improving the cleaning effect. The cleaning plate 3104 is fixedly connected to the scraper 6. When rotating, it can drive the scraper 6 to clean the filter plate 5, preventing the filter plate 5 from clogging and affecting the air intake efficiency. The connecting moving component 3103 enables on-demand cleaning and reduces ineffective operation. This combination of air jetting and physical wiping solves the problem of poor effect of a single cleaning method, ensuring that the lens is cleaned without dead angles. It not only significantly improves the clarity and recognition effect of the monitoring image, but also reduces dust wear on the lens and extends the service life of the camera body 1. At the same time, by cleaning the filter plate 5 in conjunction with the cleaning mechanism, it ensures the continuous and stable operation of the cleaning mechanism. The cleaning plate 3104 has a flow channel inside, which is connected to the dust removal nozzle 3108. Several sets of impellers 8 are rotatably connected inside the flow channel, and these impellers 8 are fixedly connected to several sets of brush rings 3107. The flow channel inside the cleaning plate 3104, connected to the dust removal nozzle 3108, provides a smooth flow channel for the gas delivered by the air collecting column 3101, ensuring that the gas efficiently reaches the dust removal nozzle 3108. The impellers 8 are fixedly connected to the brush rings 3107 within the flow channel. When the gas flows within the channel, the impellers 8 are not shown in the figure. Its flow structure is achieved using existing technology and can be adjusted according to actual usage needs. It drives the impeller 8 to rotate, which in turn drives the brush ring 3107 to rotate synchronously. This causes the brush ring 3107 to form a rotating wiping action when wiping the lens, which not only enhances the cleaning power of stubborn dust, but also makes the wiping more even and comprehensive, ensuring that the lens is thoroughly cleaned without residue, and avoiding dust affecting the clarity of the monitoring image. At the same time, the rotating wiping method can reduce the hard friction between the brush ring 3107 and the lens, reduce the risk of lens wear, and further ensure the performance and service life of the camera body 1. Among them, micro switches 9 are fixedly connected to the inner sides of the two sets of cleaning plates 3104. The micro switches 9 are existing technology, and the micro switches 9 are electrically connected to the rotary joint 3106 through wires. A trigger bar 10 is provided on one side of the micro switch 9, and the trigger bar 10 is fixedly connected to the camera body 1. Each set of cleaning plates 3104 has a micro switch 9 on its inner side, which is electrically connected to the rotary joint 3106 through wires. The trigger bar 10 is fixed to the camera body 1. Under the action of the air collection cleaning mechanism 3, the cleaning plates 3104 can realize bidirectional cleaning action of forward or backward. When a set of cleaning plates 3104 rotates to When in contact with the trigger bar 10, the corresponding micro switch 9 is triggered, and the cleaning plate 3104 is located at the camera end of the camera body 1. The rotary joint 3106 then supplies gas to it to start the cleaning action. The other cleaning plate 3104 only rotates with the mechanism and does not perform cleaning without air supply. This linkage design realizes automatic and precise control of the cleaning process, avoids energy waste caused by ineffective air supply, and ensures that each cleaning is accurately applied to the camera lens to ensure the cleaning effect. It also makes the cleaning action accurately match the monitoring direction of the camera body 1, further improving the efficiency of the device operation. See attached document Figure 4-7 The connecting movable component 3103 includes a movable ring 31031, which is rotatably connected to the mounting base 2. A movable groove is provided on the inner side of the movable ring 31031, and three sets of insert blocks 31032 are slidably connected inside the movable groove. These three sets of insert blocks 31032 are slidably connected to the outer side of the rotating ring 305. An electromagnetic block 31033 is elastically connected to the three sets of insert blocks 31032 via a tension spring. The electromagnetic block 31033 is existing technology and is fixedly connected to the rotating ring 305. The electromagnetic block 31033 and the insert blocks 31032 are magnetically repelled. The movable ring 31031 is rotatably connected to the mounting base 2, and the movable groove on its inner side provides stable sliding space for the insert blocks 31032. The three sets of insert blocks 31032 are slidably engaged with the outer side of the rotating ring 305 and elastically connected to the rotating ring 305 via a tension spring. The tension spring can drive... The insertion block 31032 automatically resets, ensuring the timeliness and accuracy of component reset. The electromagnetic block 31033 is fixed to the rotating ring 305 and can precisely control the extension and retraction of the insertion block 31032 through electromagnetic force. When the electromagnetic block 31033 is energized, it generates a magnetic repulsion force with the insertion block 31032, pushing the insertion block 31032 into the moving slot, thus achieving a stable connection between the rotating ring 305 and the moving ring 31031. When the power is off, the tension spring pulls the insertion block 31032 to reset, and the two quickly separate. This design makes the connection and separation of the rotating ring 305 and the moving ring 31031 flexible and controllable. It ensures stable connection when the cleaning mechanism needs power transmission, avoiding transmission slippage that affects the cleaning effect, and can also disconnect in time when not in operation, reducing component wear caused by ineffective transmission, saving energy, and improving the accuracy and coordination of the air collection and cleaning mechanism 3, ensuring that the overall device operates in an orderly and efficient manner. The electromagnetic block 31033 is electrically connected to a trigger switch 11 via a wire. The trigger switch 11 is existing technology and is fixedly connected to the interior of the gas collecting column 3101. A compression ring 12 is located on the top of the trigger switch 11, and the compression ring 12 is elastically connected to the gas collecting column 3101 via an elastic compression rod. The electromagnetic block 31033 is electrically connected to the trigger switch 11 inside the gas collecting column 3101 via a wire, and the compression ring 12 is elastically connected to the gas collecting column 3101 via an elastic compression rod. When the gas pressure inside the gas collecting column 3101 reaches a set value... Gas pushes the extrusion ring 12 to compress the elastic extrusion rod. The extrusion ring 12 triggers the trigger switch 11, which in turn controls the on / off state of the electromagnetic block 31033, realizing the automatic linkage of the connecting moving component 3103. This can automatically adjust the operating state of the cleaning mechanism according to the gas pressure in the gas collecting column 3101, ensuring that the cleaning action is started when the gas is sufficient and stops or waits for gas replenishment when the gas is insufficient, avoiding ineffective operation, saving energy, and also preventing the equipment from being damaged by excessive pressure in the gas collecting column 3101, improving the operating stability and safety of the device, and extending the service life of the equipment. It is worth noting that in the above embodiments of the present invention, the sliding and relative movement between the moving parts are all achieved and constrained by conventional limiting and guiding structures (not fully shown in the figures) in the art, to ensure the coordinated function of each mechanism and the reliable running trajectory. For the specific selection of elastic elements such as springs and other key components (such as elastic coefficient, specifications, etc.), those skilled in the art can make appropriate selections based on the working condition parameters such as pressure, frequency, and load in the actual application scenario to meet the performance requirements of long-term stable operation of the device. In addition, according to the specific use environment and protection requirements, conventional sealing, protection or additional limiting structures can also be added to the relevant components. The replacement, selection and conventional adjustment of the above components are all achievable by those skilled in the art based on their understanding of the present invention, and also fall within the protection scope of the present invention.

[0021] Working principle: During use, the drive source drives the camera body 1 to rotate through the transmission rod and reducer, which can realize all-round building monitoring and ensure smooth rotation without affecting the image clarity. The rotation of the camera body 1 will synchronously drive the two sets of symmetrical ratchet 301 in the air collection and cleaning mechanism 3 to operate. The ratchet 301 and the pawl 302 mesh with each other, and under the elastic action of the compression spring, drive the transmission ring 303 to move stably. The three sets of push rings 304 on the outside of the transmission ring 303 transmit power to the rotating ring 305 through the compression spring. At this time, the stop block 3081 in the movable positioning component 308 is tightly attached to the sealing ring 309 under the action of the spring, positioning the rotating ring 305 and the push ring 304. When the moving ring 304 moves to the designated position, the extrusion block 3083 connected to it will extrude the inclined block 3082 on one side of the stop block 3081, causing the stop block 3081 to extend and retract to release the limit on the extrusion plate 306. The rotating ring 305 then moves under the thrust of the extrusion spring, thereby driving the three sets of extrusion plates 306 to move. The extrusion plate 306 cooperates with the moving plate 307, and the space between them is extruded by the elastic action of the return spring, pushing the gas to the gas collection column 3101. Then, the movement of the extrusion plate 306 will contact the inclined block 3082 on the stop block 3081 on the front side of the moving plate 307 through the extrusion block 3083, causing the stop block 3081 to move, thereby causing the moving plate 307 to move under the action of the return spring. Meanwhile, the air inlet groove on the outside of the sealing ring 309 is connected to the air inlet ring 4 fixed on the mounting base 2. External gas enters the sealing ring 309 after being filtered by the filter plate 5 on the outside of the air inlet ring 4 to remove dust and impurities, thus preventing contaminants from clogging the air passage or wearing internal components. The continuous action of the extrusion plate 306 will stably transport the gas in the sealing ring 309 to the gas collecting column 3101 through the one-way valve. The one-way valve effectively prevents gas backflow and ensures one-way gas transmission. When the gas in the gas collecting column 3101 accumulates to a certain pressure, it will push the extrusion ring 12 to compress the elastic extrusion rod, triggering the internal contact. The trigger switch 11 controls the electromagnetic block 31033 to be energized at a time via a wire. It is worth noting that the trigger switch 11 has a built-in timing module, which can start the electromagnetic block 31033 at a time after triggering. The electromagnetic block 31033 and the insertion block 31032 are magnetically repelled, pushing the insertion block 31032 to slide along the moving groove on the inner side of the moving ring 31031, realizing a stable connection between the rotating ring 305 and the moving ring 31031, allowing the cleaning mechanism to obtain continuous power. When the power is cut off, the insertion block 31032 will reset under the action of the tension spring, and the two will quickly separate, reducing ineffective wear. Next, the gas collection column 3101 delivers gas to the rotary joint 3106 via a hose. When a set of cleaning plates 3104 rotates to contact the trigger strip 10 on the camera body 1, the micro switch 9 inside is triggered, and the rotary joint 3106 precisely delivers gas to that set of cleaning plates 3104. The gas is then introduced into the flow groove inside the cleaning plate 3104 through a pipe. The flow groove is connected to the dust removal nozzle 3108 to ensure smooth gas delivery. The gas in the flow groove drives the impeller 8 to rotate, and the impeller 8 interacts with the brush ring. 3107 is fixedly connected, which in turn drives the brush ring 3107 to rotate (at the same time, the rotation difference of the camera body 1 will drive the cleaning plate 3104 to move in both directions, and the movement in either direction can effectively clean). The dust removal nozzle 3108 first sprays gas to blow away the floating dust on the lens surface and the dust that is wiped off later. The rotating brush ring 3107 then performs physical wiping at the same time to remove stubborn stains. The brush ring 3107 and the dust removal nozzle 3108 on the rear side will also perform a second cleaning of the lens to ensure that there are no dead corners in the cleaning. Finally, the cleaning plate 3104 is fixedly connected to the scraper 6. While rotating the cleaning lens, the scraper 6 will drive the cleaning plate 5 to clean the dust on the surface of the filter plate 5, preventing the filter plate 5 from being blocked and affecting the air intake efficiency, and ensuring the continuous and stable operation of the cleaning mechanism. When cleaning is completed or the pressure in the air collection column 3101 drops, the trigger switch 11 is reset, the electromagnetic block 31033 is de-energized, the insertion block 31032 is reset under the action of the tension spring, the rotating ring 305 and the moving ring 31031 are separated, the cleaning mechanism stops ineffective operation, and waits for the next cleaning cycle. The whole process does not affect the normal monitoring function of the camera body 1, and can solve the problem of lens dust accumulation through automatic cleaning, while reducing manual maintenance costs and extending the service life of the equipment.
