Description

Technical Field

[0001] This utility model belongs to the field of camera device technology, specifically relating to a camera device inside a pipeline. Background Technology

[0002] Pipeline internal camera devices are specialized equipment used to inspect and monitor the internal conditions of pipelines, and are widely used in industries such as industrial, municipal, and construction. They enable real-time observation, data collection, and analysis of the pipeline's interior using visual or sensor technology.

[0003] Application No. 202021403916.9 discloses a camera inspection device for pipelines. "Through the combined use of a sliding fixing block that can slide left and right, an upper fixing block that can move up and down, and a lower fixing block, the device can fix pipelines of different diameters and lengths, expanding its application range. By installing cameras on the upper and lower surfaces and front and rear of the camera mechanism's connecting block, it can perform all-round observation and inspection of the pipeline. Simultaneously, the electric telescopic rod can precisely drive the camera mechanism to move left and right within the pipeline, improving the device's inspection accuracy." However, when the camera is working, due to the complex internal environment of the pipeline, dust, particulate matter, and other impurities suspended in the air easily accumulate on the front wall, forming stubborn dirt. This dirt not only affects the camera's imaging quality, causing blurry and distorted images, but may also hinder the normal operation of the lens, affecting the accuracy and reliability of the entire camera operation. Furthermore, the lens cap, as a crucial component of the camera, is directly exposed to the internal environment of the pipeline but lacks a dedicated protective device. This makes it highly susceptible to impacts from external objects. For example, during pipeline construction or maintenance, tools, equipment, or debris inside the pipeline may accidentally collide with the lens cover, causing it to crack, scratch, or deform. Utility Model Content

[0004] The purpose of this utility model is to provide a camera device inside a pipeline to solve the problems mentioned in the background art, where the complex environment inside the pipeline causes dust and other impurities to accumulate on the front wall, forming stubborn dirt that affects image quality and lens operation, and the lack of protection for the lens front cover makes it susceptible to damage from impacts.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an in-pipe camera device, comprising: a camera device body, a lens front cover disposed at the front end of the camera device body, an air pump disposed on one side of the camera device body, a mounting plate fixed on the air pump, an air guide pipe connected to the air pump's outlet end, a flexible hose connected to the outlet end of the air guide pipe, an outlet pipe connected to the outlet end of the flexible hose, a first gear mounted on the outer wall of the outlet pipe, and the outlet end of the outlet pipe facing the front end of the outer wall of the lens front cover, a motor mounted on the side wall of the mounting plate, a rotating shaft connected to the output of the motor, a bearing mounted on the end of the rotating shaft away from the motor, a second gear mounted on the outer wall of the rotating shaft, and the first gear and the second gear being connected by meshing teeth; furthermore, the outlet pipe adopts a curved design. This design allows the outlet pipe to deliver airflow at a more flexible angle and path, ensuring that the airflow can fully cover the entire surface of the lens front cover. Even in complex pipe environments, the curved pipe can effectively guide airflow and avoid cleaning dead zones. Meanwhile, the curved air duct allows for more precise control of airflow direction, ensuring that the airflow hits the front wall of the lens cap at the optimal angle. This design not only improves cleaning efficiency but also prevents unnecessary impact or wear on the lens cap caused by improper airflow direction.

[0006] Preferably, the air pump has a filter box installed at its air inlet end, the filter box contains multiple filter screens, the air inlet end of the filter box is connected to an air inlet pipe, the air inlet pipe is fitted with a cover, the cover has multiple filter holes, filter cotton is provided between the air inlet pipe and the cover, the inner wall of the cover has a threaded groove, the outer wall of the air inlet pipe has an external thread, and the threaded groove and the external thread are compatible.

[0007] A protective cover is installed on one side of the mounting plate, and the protective cover houses the motor, the first gear and the second gear. Connecting components are provided between the protective cover and the camera device body, as well as between the filter box and the camera device body.

[0008] The connecting assembly includes a connecting plate, a fixing plate, and bolts. The connecting plate is installed at the bottom of the protective cover and the filter box. The fixing plate is installed on the outer wall of the camera device body. The bolts are installed between the connecting plate and the fixing plate. A slot is provided on the upper end face of the fixing plate. A block is installed at the bottom end of the connecting plate. The slot and the block are compatible.

[0009] Through the above technical solution:

[0010] In use, the camera unit itself is the core component of the entire pipeline imaging system. It integrates a camera, image sensor, and necessary electronic control components, ensuring stable and efficient image acquisition in various pipeline environments. It also features a built-in lighting mechanism for easy operation within the pipeline. To protect the lens from dust, dirt, and other potential damage, a lens cap is cleverly positioned at the front of the camera unit. This cap not only provides physical protection but also allows for quick cleaning via a built-in cleaning system when needed, ensuring the lens remains sharp at all times.

[0011] When the front wall of the lens cap needs cleaning, the operator simply starts the air pump and motor. The air pump begins working, guiding airflow through the air duct and hose to the exhaust duct. The hose design allows the exhaust duct to swing freely within a certain range, ensuring that the airflow effectively covers the entire surface of the lens cap. After the motor starts, it drives the second gear to rotate via a shaft. The second gear meshes with the first gear, driving the exhaust duct to swing slightly. This swinging design ensures that the airflow evenly sweeps across the front wall of the lens cap, effectively removing attached dust and dirt. The airflow from the exhaust duct blows towards the lens cap at a certain speed and angle, blowing dust and impurities off the surface, achieving a cleaning effect. During the cleaning process, the lens cap remains stationary, ensuring that the cleaning process does not affect the stability of the camera device. Through swinging, the airflow from the exhaust duct can sweep across the front wall of the lens cap at different angles and paths, avoiding cleaning dead zones that may be caused by airflow in a single direction. In addition, the swinging increases the contact time between the airflow and the surface of the lens cap, making it easier for dust and dirt attached to the surface to be carried away by the airflow. Moreover, the swing design allows the cleaning system to adapt to lens caps of different shapes and sizes, ensuring effective cleaning in various situations.

[0012] To ensure the cleanliness of the air blown out of the outlet pipe, a filter box is installed at the air pump's inlet. The filter box contains multiple filter screens that effectively filter dust and impurities from the air. An air inlet pipe connects to the filter box's inlet to introduce outside air. A cover is installed above the air inlet pipe to protect the inlet and prevent large particles from entering. Multiple filter holes on the cover further filter the air. Filter cotton is located between the air inlet pipe and the cover, providing an additional filtration layer to ensure air cleanliness. The inner wall of the cover has threaded grooves, and the outer wall of the air inlet pipe has external threads; these fit together for easy cover removal. The filter cotton can be easily removed and replaced by unscrewing the cover, ensuring the filtration system remains effective.

[0013] A protective cover is mounted on one side of the mounting plate to house and protect the motor, the first gear, and the second gear. The cover is designed to prevent damage to the gears and motor from the external environment while allowing necessary mechanical movement.

[0014] The connecting plate is installed at the bottom of the protective cover and filter box. The fixing plate is installed on the outer wall of the camera unit body. Bolts are installed between the connecting plate and the fixing plate for fastening the connection and ensuring the stability of the overall structure. The upper end face of the fixing plate has a slot, and the bottom end of the connecting plate has a locking block. Initial connection is achieved by aligning the slot and the locking block, and then the bolts are tightened to further strengthen the connection between the connecting plate and the fixing plate, ensuring a stable connection between the components.

[0015] The front end of the outer wall of the lens front cover is provided with multiple protective components. The protective components include a hollow cylinder, a movable rod, and a protective plate. The hollow cylinder is connected to the front end of the outer wall of the lens front cover. A portion of the movable rod is located inside the hollow cylinder. A limiting component is provided between the hollow cylinder and the movable rod. The protective plate is installed at the end of the movable rod located outside the hollow cylinder. An elastic component is provided inside the protective components.

[0016] Preferably, the limiting component includes a limiting groove and a limiting block. The limiting groove is formed on the outer wall of the movable rod, and the limiting block is installed on the inner wall of the hollow cylinder. The limiting groove and the limiting block are compatible with each other.

[0017] The elastic component includes a spring, a first soft pad, and a second soft pad. The spring is connected between the hollow cylinder and the movable rod. The first soft pad is installed on the front end of the outer wall of the protective plate. The second soft pad is annular and is installed on the front end of the outer wall of the hollow cylinder.

[0018] Through the above technical solution:

[0019] In use, the hollow cylinder, as the core structural element of the entire protective assembly, is securely fixed to the front end of the lens cap. Its main function is to provide precise guidance and support for the movable rod, while also serving as a fixing point for the elastic components, ensuring the stable operation of these critical parts.

[0020] The movable rod is ingeniously designed, with one part cleverly nested inside the hollow cylinder and the other extending to the outside. This design allows the movable rod to serve both as a support and moving part of the protective plate, and to make controlled, small-amplitude displacements when subjected to external impacts, effectively absorbing and dispersing the impact force. The protective plate, as the first physical barrier, faces the external environment directly, blocking dust, debris, and other possible physical damage.

[0021] To prevent excessive displacement of the movable rod under impact and subsequent structural damage, the precise fit between the limiting groove and the limiting block is crucial. The limiting groove is precisely cut into the outer wall of the movable rod, while the limiting block is securely installed on the inner wall of the hollow cylinder. This design ensures that the movable rod can safely displace under the constraint of the limiting groove and the limiting block after impact, and accurately return to its original position after impact thanks to the elastic restoring force of the spring. The limiting block and the hollow cylinder can be connected by threads. During installation, first insert the movable rod, aligning the limiting groove with the limiting block, then screw the limiting block into the limiting groove. To enhance the connection strength, welding can be added for a more robust connection.

[0022] Under normal circumstances, the movable rod remains in its initial position within the hollow cylinder under the elastic force of the spring, ensuring continuous and stable protection from the protective plate. When an external object impacts the protective plate, the impact force is transmitted to the spring via the movable rod, causing the spring to compress instantly and absorb some of the impact force. Simultaneously, the movable rod undergoes a slight displacement under the constraint of the limiting groove and limiting block, further absorbing and dispersing the impact force. The first and second soft pads work together as auxiliary buffer elements to ensure that the impact force is effectively absorbed and dispersed, providing comprehensive protection for the lens cap and hollow cylinder from damage.

[0023] After the impact, the spring's elastic restoring force quickly returns the movable rod to its original position, and the protective plate also returns to its original position simultaneously, ready to withstand the next impact. This design not only provides efficient protection and cushioning, but also ensures the reliability and durability of the protective components under various impact environments, providing all-round protection for the lens cover of the camera device inside the pipeline.

[0024] Compared with the prior art, the beneficial effects of this utility model are:

[0025] (1) This utility model achieves cleaning of the front wall of the lens cover by setting up components such as an air pump, a motor, a first gear, and a second gear. In use, the operator only needs to start the air pump and motor. The air pump delivers airflow to the outlet pipe through an air guide pipe and a hose. The hose design allows the outlet pipe to swing freely within a certain range, ensuring that the airflow can fully cover the surface of the lens cover. After the motor starts, it drives the second gear to rotate via a shaft. The second gear meshes with the first gear, thereby driving the outlet pipe to swing slightly. This swinging design has advantages such as uniform cleaning, avoiding cleaning dead spots, enhanced contact, and strong adaptability, ensuring a more efficient and comprehensive cleaning process, and adapting to various complex environments and needs.

[0026] (2) This utility model provides protection for the lens front cover by incorporating components such as a protective plate, a movable rod, a spring, and soft pads. In use, the hollow cylinder is fixed to the front end of the lens front cover, providing support for the movable rod and achieving elastic fixation. The protective plate acts as the first barrier, blocking external dust and debris. When an external object impacts the protective plate, the impact force is transmitted to the spring through the movable rod. The spring compresses, absorbing part of the impact force, while the movable rod undergoes a small displacement, further dispersing the impact. The first and second soft pads provide auxiliary cushioning, protecting the lens front cover and the hollow cylinder. After the impact, the spring causes the movable rod to quickly return to its original position, and the protective plate also returns to its original position, ready to withstand the next impact. This design provides efficient protection and cushioning, ensuring the reliability and durability of the protective components and providing comprehensive protection for the lens front cover.

[0036] Please see Figures 1-6 As shown, this utility model provides the following technical solution: an in-pipe camera device, comprising: a camera device body 1, a lens front cover 2 disposed at the front end of the camera device body 1, an air pump 3 disposed on one side of the camera device body 1, a mounting plate 4 fixed on the air pump 3, an air guide pipe 5 connected to the air outlet end of the air pump 3, a hose 6 connected to the air outlet end of the air guide pipe 5, an air outlet pipe 7 connected to the air outlet end of the hose 6, a first gear 8 mounted on the outer wall of the air outlet pipe 7, and the air outlet end of the air outlet pipe 7 facing the front end of the outer wall of the lens front cover 2, a motor 9 mounted on the side wall of the mounting plate 4, a rotating shaft 10 connected to the output of the motor 9, a bearing 12 mounted on the end of the rotating shaft 10 away from the motor 9, a second gear 11 mounted on the outer wall of the rotating shaft 10, and the first gear 8 and the second gear 11 being connected by meshing teeth; furthermore, the air outlet pipe 7 adopts a curved design. This design allows the air outlet pipe 7 to deliver airflow at a more flexible angle and path, ensuring that the airflow can fully cover the entire surface of the lens front cover 2. Even in complex duct environments, the curved duct effectively guides airflow, preventing cleaning dead zones. Simultaneously, the curved exhaust duct 7 allows for more precise control of airflow direction, ensuring the airflow hits the front wall of the lens cover 2 at the optimal angle. This design not only improves cleaning efficiency but also prevents unnecessary impact or wear on the lens cover 2 due to improper airflow direction.

[0037] Furthermore, a filter box 14 is installed at the air inlet end of the air pump 3. The filter box 14 is provided with multiple filter screens 15. The air inlet end of the filter box 14 is connected to an air inlet pipe 16. A cover 17 is installed on the air inlet pipe 16, and multiple filter holes are opened on the cover 17. Filter cotton 18 is provided between the air inlet pipe 16 and the cover 17. A threaded groove 19 is opened on the inner wall of the cover 17, and an external thread 20 is opened on the outer wall of the air inlet pipe 16. The threaded groove 19 and the external thread 20 are compatible.

[0038] A protective cover 13 is installed on one side of the mounting plate 4, and the protective cover 13 accommodates the motor 9, the first gear 8 and the second gear 11. Connecting components are provided between the protective cover 13 and the camera device body 1, and between the filter box 14 and the camera device body 1.

[0039] The connecting assembly includes a connecting plate 21, a fixing plate 22, and bolts 25. The connecting plate 21 is installed at the bottom of the protective cover 13 and the filter box 14. The fixing plate 22 is installed on the outer wall of the camera device body 1. The bolts 25 are installed between the connecting plate 21 and the fixing plate 22. The upper end face of the fixing plate 22 is provided with a slot 23. The bottom end of the connecting plate 21 is provided with a locking block 24. The slot 23 and the locking block 24 are compatible.

[0040] Through the above technical solution:

[0041] In use, the camera unit 1 is the core component of the entire pipeline imaging system. It integrates a camera, image sensor, and necessary electronic control components, ensuring stable and efficient image acquisition in various pipeline environments. It also features a built-in lighting mechanism for easy operation within the pipeline. To protect the lens from dust, dirt, and other potential damage, a lens cover 2 is cleverly positioned at the front of the camera unit 1. This cover not only provides physical protection but also allows for quick cleaning via a built-in cleaning system when needed, ensuring the lens remains clear at all times.

[0042] When the front wall of the lens cover 2 needs cleaning, the operator simply needs to start the air pump 3 and the motor 9. The air pump 3 begins operation, guiding airflow through the air guide pipe 5 and the hose 6 to the air outlet pipe 7. The design of the hose 6 allows the air outlet pipe 7 to swing freely within a certain range, ensuring that the airflow effectively covers the entire surface of the lens cover 2. After the motor 9 starts, it drives the second gear 11 to rotate via the rotating shaft 10. The second gear 11, by meshing with the first gear 8, drives the air outlet pipe 7 to swing slightly. This swinging design ensures that the airflow evenly sweeps across the front wall of the lens cover 2, effectively removing attached dust and dirt. The airflow from the air outlet pipe 7 blows towards the lens cover 2 at a certain speed and angle, blowing dust and impurities away from the surface, achieving a cleaning effect. During the cleaning process, the lens cover 2 remains stationary, ensuring that the cleaning process does not affect the stability of the camera device body 1. Through swinging, the airflow from the air outlet pipe 7 can sweep across the front wall of the lens cover 2 at different angles and paths, avoiding cleaning dead zones that may be caused by airflow in a single direction. Furthermore, the oscillation increases the contact time between the airflow and the surface of the lens front cover 2, making it easier for dust and dirt adhering to the surface to be carried away by the airflow. Moreover, the oscillation design allows the cleaning system to adapt to different shapes and sizes of lens front covers 2, ensuring effective cleaning in various conditions.

[0043] To ensure the cleanliness of the air blown out of the outlet pipe 7, a filter box 14 is installed at the air inlet of the air pump 3. The filter box 14 contains multiple filter screens 15, which effectively filter dust and impurities from the air. An air inlet pipe 16 is connected to the air inlet of the filter box 14 to introduce outside air. A cover 17 is installed above the air inlet pipe 16 to protect the air inlet and prevent large particles from entering. Multiple filter holes are provided on the cover 17 for further air filtration. Filter cotton 18 is located between the air inlet pipe 16 and the cover 17, providing an additional filtration layer to ensure air cleanliness. The inner wall of the cover 17 has a threaded groove 19, and the outer wall of the air inlet pipe 16 has an external thread 20; the two are compatible, facilitating the removal of the cover 17. By unscrewing the cover 17, the filter cotton 18 can be easily removed and replaced, ensuring the continuous effectiveness of the filtration system.

[0044] A protective cover 13 is mounted on one side of the mounting plate 4 to house and protect the motor 9, the first gear 8, and the second gear 11. The protective cover 13 is designed to prevent damage to the gears and motor 9 from the external environment while allowing necessary mechanical movement.

[0045] The connecting plate 21 is installed at the bottom of the protective cover 13 and the filter box 14. The fixing plate 22 is installed on the outer wall of the camera device body 1. Bolts 25 are installed between the connecting plate 21 and the fixing plate 22 for fastening the connection and ensuring the stability of the overall structure. The upper end face of the fixing plate 22 has a slot 23, and the bottom end of the connecting plate 21 has a locking block 24. A preliminary connection is achieved by aligning the slot 23 and the locking block 24. Then, the bolts 25 are tightened to further strengthen the connection between the connecting plate 21 and the fixing plate 22, ensuring a stable connection between the components.

[0046] Please see Figures 1-7 As shown, the front end of the outer wall of the lens front cover 2 is provided with multiple protective components. The protective components include a hollow cylinder 26, a movable rod 27 and a protective plate 28. The hollow cylinder 26 is connected to the front end of the outer wall of the lens front cover 2. A portion of the movable rod 27 is located inside the hollow cylinder 26. A limiting component is provided between the hollow cylinder 26 and the movable rod 27. The protective plate 28 is installed at the end of the movable rod 27 located outside the hollow cylinder 26. An elastic component is provided inside the protective components.

[0047] Furthermore, the limiting component includes a limiting groove 32 and a limiting block 33. The limiting groove 32 is formed on the outer wall of the movable rod 27, and the limiting block 33 is installed on the inner wall of the hollow cylinder 26. The limiting groove 32 and the limiting block 33 are compatible with each other.

[0048] The elastic component includes a spring 29, a first soft pad 30, and a second soft pad 31. The spring 29 is connected between the hollow cylinder 26 and the movable rod 27. The first soft pad 30 is installed on the front end of the outer wall of the protective plate 28. The second soft pad 31 is annular and is installed on the front end of the outer wall of the hollow cylinder 26.

[0049] Through the above technical solution:

[0050] In use, the hollow cylinder 26, as the core structural element of the entire protective assembly, is securely fixed to the front end of the outer wall of the lens cap 2. Its main function is to provide precise guidance and support for the movable rod 27, while also serving as a fixing point for the elastic components, ensuring the stable operation of these critical parts.

[0051] The movable rod 27 is ingeniously designed, with one part cleverly nested inside the hollow cylinder 26 and the other part extending to the outside. This design allows the movable rod 27 to serve as both a support and moving component for the protective plate 28, and also to allow for controlled, small-amplitude displacement when subjected to external impacts, effectively absorbing and dispersing the impact force. The protective plate 28, as the first physical barrier, faces the external environment directly, blocking dust, debris, and other possible physical damage.

[0052] To prevent excessive displacement of the movable rod 27 under impact and subsequent structural damage, the precise fit between the limiting groove 32 and the limiting block 33 is crucial. The limiting groove 32 is precisely cut into the outer wall of the movable rod 27, while the limiting block 33 is firmly installed on the inner wall of the hollow cylinder 26. This design ensures that the movable rod 27 can safely displace under the constraint of the limiting groove 32 and the limiting block 33 after impact, and accurately return to its original position after impact thanks to the elastic restoring force of the spring 29. The limiting block 33 and the hollow cylinder 26 can be connected by threads. During installation, first insert the movable rod 27, aligning the limiting groove 32 with the limiting block 33, then screw the limiting block 33 into the limiting groove 32. To enhance the connection strength, welding can be added for a more secure connection.

[0053] Under normal circumstances, the movable rod 27 remains in its initial position within the hollow cylinder 26 under the elastic force of the spring 29, ensuring that the protective plate 28 continuously provides stable protection. When an external object impacts the protective plate 28, the impact force is transmitted to the spring 29 via the movable rod 27, and the spring 29 compresses instantaneously, absorbing part of the impact force. At the same time, the movable rod 27 moves slightly under the restriction of the limiting groove 32 and the limiting block 33, further absorbing and dispersing the impact force. The first soft pad 30 and the second soft pad 31 work together as auxiliary buffer elements to ensure that the impact force is effectively absorbed and dispersed, providing all-round protection for the lens front cover 2 and the hollow cylinder 26 from damage.

[0054] After the impact, the elastic restoring force of the spring 29 quickly resets the movable rod 27, and the protective plate 28 also returns to its original position, ready to cope with the next impact. This design not only has efficient protection and cushioning functions, but also ensures the reliability and durability of the protective components in various impact environments, providing all-round protection for the lens cover 2 of the camera device inside the pipeline.
