Description

Technical Field

[0001] This invention belongs to the field of dome camera technology, specifically a self-cleaning dome camera for security applications. Background Technology

[0002] A dome camera, as the name suggests, is shaped like a hemisphere; it is named solely for its shape. Due to its compact size, a dome camera consists of a camera, an automatic aperture and manual zoom lens, a well-sealed dome housing, and a precision camera mounting bracket. Dome cameras generally need to work 24 hours a day, so proper maintenance can extend the camera's lifespan and ensure the stability of the image quality.

[0003] Dust covers for dome cameras tend to accumulate dust on their surface due to prolonged contact with outside air. If this dust is not cleaned, it will affect the shooting results. On the other hand, charged ions in the air may adhere to the surface of the cover due to static electricity, making them difficult to clean. Most dome cameras on the market do not have an automatic cleaning function, which will lead to a deterioration in shooting results over time. Summary of the Invention

[0004] The purpose of this invention is to provide a self-cleaning dome camera for security purposes, in order to improve the cleaning effect of the dust cover on the dome camera.

[0005] The technical solution adopted in this invention is as follows:

[0006] A self-cleaning dome camera for security purposes includes a fixing plate and a mounting base. A connecting plate is fixedly connected to the upper surface of the mounting base. A groove is formed on the upper surface of the connecting plate. A motor is installed on the inner surface of the groove. An output shaft is provided on the upper outer surface of the motor. A base plate is fixedly connected to the outer surface of the output shaft away from the motor. The camera body is installed in the middle of the upper surface of the base plate. A dust cover is fixedly connected to the edge of the upper surface of the base plate. A negative ion generator is provided on the upper surface of the connecting plate near the groove. Coils are provided on both sides of the upper surface of the connecting plate. A rotating ring is provided on the outer side of the base plate. A rotating frame is provided on the side of the rotating ring away from the base plate. A permanent magnet is fixedly connected to the bottom outer surface of the rotating frame. A brush is provided on the side of the rotating frame near the rotating ring.

[0007] By adopting the above technical solution, when dust adheres to the surface of the dust cover, the motor can be started to make the output shaft drive the base plate to rotate. The rotation of the base plate will drive the dust cover to rotate. The brush attached to the rotating frame is in contact with the outer surface of the dust cover. The brush can clean the outer surface of the dust cover while it is rotating. The negatively charged particles generated by the negative ion generator can adsorb and neutralize charged particles in the air near the dust cover, reduce static electricity, and prevent dust in the air from being adsorbed on the outer surface of the dust cover due to static electricity and making it difficult to clean. On the other hand, the battery provides power to the coil. The magnetic field generated by the coil under the action of current will interact with the permanent magnet, thereby driving the rotating frame and brush to rotate. The rotating brush can clean the dust on the surface of the dust cover. Through the combination of the above structures, the cleaning effect of the dust cover of the dome camera is improved.

[0008] In a preferred embodiment of the invention, the rotating ring includes an outer ring, a ball bearing, and an inner ring. The inner wall of the inner ring is fixedly connected to the outer side of the base plate, and the outer wall of the outer ring is fixedly connected to the inner side of the rotating frame. The ball bearing is movably installed between the outer ring and the inner ring.

[0009] By adopting the above technical solution, the outer ring, ball bearings and inner ring of the rotating ring can make the magnetic field generated by the coil under the action of current interact with the permanent magnet, thereby driving the rotating frame and brush to rotate.

[0010] In a preferred embodiment of the invention, a battery compartment is provided at the center of the bottom outer surface of the mounting base, and a storage battery is disposed inside the battery compartment.

[0011] In a preferred embodiment of the invention, the output terminal of the battery is electrically connected to the input terminals of the motor, the coil of the camera body, and the negative ion generator.

[0012] By adopting the above technical solution, the battery can provide power for starting the motor, camera body, coil and negative ion generator.

[0013] In a preferred embodiment of the invention, a cover plate is hinged to the opening of the battery compartment, and a pull ring is fixedly connected to the lower surface of the cover plate.

[0014] By adopting the above technical solution, the battery compartment can be removed by hooking the pull ring on the cover with your finger, so as to replace the battery inside the battery compartment.

[0015] In a preferred embodiment of the invention, a second groove is formed on the upper surface of the fixing plate, and an electric cylinder is fixedly connected to the inner bottom surface of the second groove. A piston rod is provided on the upper surface of the electric cylinder, and the end of the piston rod away from the electric cylinder is fixedly connected to both sides of the lower surface of the mounting base.

[0016] In a preferred embodiment of the invention, there are two grooves, two electric cylinders, and two piston rods, and the two grooves, two electric cylinders, and two piston rods are symmetrically arranged on both sides of the upper surface of the fixed plate.

[0017] By adopting the above technical solution, the extension and retraction of the piston rod can be controlled by an electric cylinder, thereby controlling the gap between the fixed plate and the mounting base. When the gap between the fixed plate and the mounting base increases, the battery inside the battery compartment can be replaced without having to remove the entire dome camera for battery replacement. The combination of the above structures improves the efficiency of replacing the battery inside the dome camera.

[0018] In a preferred embodiment of the invention, through holes are provided on the upper surfaces of both ends of the fixing plate.

[0019] By adopting the above technical solution, the lower surface of the fixing plate is attached to the wall or ceiling, and then it can be fixed by using bolts through the through holes.

[0020] In a preferred embodiment of the invention, the side of the brush away from the rotating frame is in contact with the outer surface of the dust cover.

[0021] By adopting the above technical solution, the mating brushes can clean the dust on the surface of the dust cover while rotating.

[0022] In a preferred embodiment of the invention, the two permanent magnets are mounted with opposite magnetic poles.

[0023] By adopting the above technical solution, the magnetic field generated by the coil under the action of current will interact with the permanent magnet, thereby driving the rotating frame and brush to rotate.

[0024] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0025] 1. In this invention, when dust adheres to the surface of the dust cover, the motor can be started to make the output shaft drive the base plate to rotate. The rotation of the base plate will drive the dust cover to rotate. The brush attached to the rotating frame is in contact with the outer surface of the dust cover. The brush can clean the outer surface of the dust cover in the rotating state. The negatively charged particles generated by the negative ion generator can adsorb and neutralize the charged particles in the air near the dust cover, reduce static electricity, and prevent dust in the air from being adsorbed on the outer surface of the dust cover due to static electricity and making it difficult to clean. Through the combination of the above structures, the cleaning effect of the dust cover on the hemispherical camera is improved.

[0026] 2. In this invention, a storage battery is used to provide power to the coil. The magnetic field generated by the coil under the action of the current will interact with the permanent magnet, thereby driving the rotating frame and the brush to rotate. The rotating brush can clean the dust on the surface of the dust cover, thereby improving the cleaning effect of the dust cover on the dome camera.

[0027] 3. In this invention, the extension and retraction of the piston rod can be controlled by an electric cylinder, thereby controlling the gap between the fixing plate and the mounting base. When the gap between the fixing plate and the mounting base increases, the cover plate can be hooked with a finger to remove it from the opening of the battery compartment, so as to replace the battery inside the battery compartment without having to remove the entire dome camera for battery replacement. The combination of the above structures improves the efficiency of replacing the battery inside the dome camera. Attached Figure Description

Detailed Implementation

[0033] 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 in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] The following will combine Figures 1-4 A detailed description of a self-cleaning dome camera for security purposes according to an embodiment of the present invention will be provided.

[0035] Example:

[0036] Reference Figures 1-3 A self-cleaning dome camera for security purposes includes a fixing plate 1 and a mounting base 2. A connecting plate 22 is fixedly connected to the upper surface of the mounting base 2. A groove 3 is formed on the upper surface of the connecting plate 22. A motor 4 is installed on the inner surface of the groove 3. An output shaft 5 is provided on the upper outer surface of the motor 4. A base plate 6 is fixedly connected to the outer surface of the end of the output shaft 5 away from the motor 4. Starting the motor 4 can cause the output shaft 5 to drive the base plate 6 to rotate. A camera body 7 is installed in the middle of the upper surface of the base plate 6. The camera body 7 can monitor the external environment. A negative ion generator 14 is provided on the upper surface of the connecting plate 22 near the groove 3. A dust cover 8 is fixedly connected to the edge of the upper surface of the base plate 6. The rotation of the base plate 6 can drive the dust cover 8 to rotate. The negative ion generator 14 can generate negatively charged particles that can adsorb and neutralize charged particles in the air near the dust cover 8, reduce static electricity, and prevent dust in the air from being adsorbed on the outer surface of the dust cover 8 due to static electricity and difficult to clean.

[0037] Reference Figures 1-3 A rotating ring 9 is provided on the outer side of the base plate 6. A rotating frame 10 is provided on the side of the rotating ring 9 away from the base plate 6. The overall shape of the rotating frame 10 is arc-shaped. A brush 11 is provided on the side of the rotating frame 10 near the rotating ring 9. The side of the brush 11 away from the rotating frame 10 is in contact with the outer surface of the dust cover 8. When the dust cover 8 rotates, the brush 11 attached to the rotating frame 10 is in contact with the outer surface of the dust cover 8. The brush 11 can clean the outer surface of the dust cover 8 in the rotating state. The combination of the above structures improves the cleaning effect of the dust cover 8 on the hemispherical camera.

[0038] Reference Figures 1-3 A permanent magnet 12 is fixedly connected to the bottom outer surface of the rotating frame 10. Coils 13 are provided on both sides of the upper surface of the connecting plate 22. The rotating ring 9 includes an outer ring, a ball bearing, and an inner ring. The inner wall of the inner ring is fixedly connected to the outer side of the base plate 6, and the outer wall of the outer ring is fixedly connected to the inner side of the rotating frame 10. The ball bearing is movably installed between the outer ring and the inner ring. The magnetic poles of the two permanent magnets 12 are installed in opposite directions. When the coil 13 is energized, the magnetic field generated by the coil 13 under the action of the current will interact with the permanent magnet 12, thereby driving the rotating frame 10 and the brush 11 to rotate. The rotating brush 11 can clean the dust on the surface of the dust cover 8, thereby improving the cleaning effect of the dust cover 8 on the hemispherical camera.

[0039] Reference Figure 1 and Figure 4A battery compartment 15 is provided at the center of the bottom outer surface of the mounting base 2. A storage battery 16 is installed inside the battery compartment 15. The output end of the storage battery 16 is electrically connected to the input end of the motor 4, the camera body 7 coil 13 and the negative ion generator 14. The storage battery 16 can provide power for the start-up of the motor 4, the camera body 7, the coil 13 and the negative ion generator 14.

[0040] Reference Figure 1 and Figure 4 A second groove 18 is formed on the upper surface of the fixing plate 1. An electric cylinder 19 is fixedly connected to the inner bottom surface of the second groove 18. A piston rod 20 is provided on the upper surface of the electric cylinder 19. The end of the piston rod 20 away from the electric cylinder 19 is fixedly connected to both sides of the lower surface of the mounting base 2. The extension and retraction of the piston rod 20 can be controlled by the electric cylinder 19, thereby controlling the gap between the fixing plate 1 and the mounting base 2. There are two second grooves 18, electric cylinders 19, and piston rods 20, and the two second grooves 18, electric cylinders 19, and piston rods 20 are aligned. The battery compartment 15 is hinged to the opening of the battery compartment 15 on both sides of the upper surface of the fixing plate 1. The lower surface of the cover plate 17 is fixedly connected with a pull ring. When the gap between the fixing plate 1 and the mounting base 2 increases, the pull ring on the cover plate 17 can be hooked with a finger to remove it from the opening of the battery compartment 15 so as to replace the battery 16 inside the battery compartment 15. It is not necessary to remove the entire dome camera to replace the battery 16. The combination of the above structures improves the efficiency of replacing the battery 16 inside the dome camera.

[0041] The implementation principle of a self-cleaning dome camera for security purposes according to this application is as follows:

[0042] When using this self-cleaning dome camera, first, the lower surface of the mounting plate 1 can be attached to the wall or ceiling. Then, bolts can be used to fix it through the through hole 21. Then, the electric cylinder 19 can be controlled to extend and retract the piston rod 20, thereby controlling the gap between the mounting plate 1 and the mounting base 2. When the gap between the mounting plate 1 and the mounting base 2 becomes larger, the pull ring on the cover plate 17 can be hooked with a finger to remove it from the opening of the battery compartment 15, so that the battery 16 inside the battery compartment 15 can be replaced without removing the entire dome camera to replace the battery 16. The combination of the above structures improves the efficiency of replacing the battery 16 inside the dome camera.

[0043] When it is necessary to clean the dust on the outer surface of the dust cover 8, the motor 4 can be started to make the output shaft 5 drive the base plate 6 to rotate. The rotation of the base plate 6 will drive the dust cover 8 to rotate. The brush 11, which is attached to the rotating frame 10, is in contact with the outer surface of the dust cover 8. The brush 11 can clean the outer surface of the dust cover 8 in the rotating state. Meanwhile, the negatively charged particles generated by the negative ion generator 14 can adsorb and neutralize the charged particles in the air near the dust cover 8, reduce static electricity, and prevent dust in the air from being adsorbed on the outer surface of the dust cover 8 due to static electricity and making it difficult to clean. Through the cooperation of the above structures, the cleaning effect of the dust cover 8 on the hemispherical camera is improved.

[0044] On the other hand, the battery 16 provides power to the coil 13. The magnetic field generated by the coil 13 under the action of the current will interact with the permanent magnet 12, thereby driving the rotating frame 10 and the brush 11 to rotate. The rotating brush 11 can clean the dust on the surface of the dust cover 8, thereby improving the cleaning effect of the dust cover 8 on the dome camera.
