Description

Technical Field

[0001] The utility model relates to the technical field of security cameras, in particular to a linkage type security camera. Background Art

[0002] The linkage security camera is an intelligent security device. It sets association rules with other devices. When the camera detects specific events or environmental changes, it can trigger the operation of other devices to achieve intelligent linkage control.

[0003] A Chinese patent discloses a smart security camera with a publication number of CN216905015U, and the application date is 2021.12.26. The patented technology adds a protective shell to the outside of the security camera body to protect it from bumps, and after the traction frame is installed under the protective shell, when the motor inside the mounting frame drives the rotating arm to rotate, the bristles on the surface of the rotating arm sweep the dust on the surface of the security camera body. However, the above device drives the bristles to clean the camera through the motor drive, and since the bristles only contact the surface of the camera once after one rotation, the cleaning efficiency is not high, and the bristles may scratch the mirror when they contact the detection end mirror of the camera, affecting the effect of the subsequent use of the camera. Therefore, the inventor provides a linkage security camera to solve the problems raised in the above background technology. Summary of the invention

[0004] The utility model aims to provide a linkage type security camera, which can achieve efficient cleaning of the detection end of the security camera and prevent the surface of the detection end of the camera from being scratched.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] A linkage security camera comprises a security camera body, one side of the security camera body is fixedly connected to a mounting bracket, the top of the security camera body is provided with a cleaning mechanism, the cleaning mechanism comprises a connecting frame, the connecting frame is in the shape of a Chinese character "冂", and the inner two sides of the connecting frame are fixedly connected to the two side surfaces of the security camera body, movable grooves are provided on the inner two sides of the connecting frame, the inner two sides of the movable groove on one side are rotatably connected to a rotatable threaded rod, a moving block is threadedly connected to the threaded rod, one side of the moving block is rotatably connected to a rotatable rotating rod, a cleaning roller is fixedly connected to the outer surface of the rotating rod, the outer surface of the cleaning roller is made of microfiber cloth, and a heat dissipation mechanism is provided inside the connecting frame.

[0007] As a further solution of the utility model: One side of the top of the connection frame is fixedly connected with a motor, and the output end of the motor is fixedly connected with the top end of the threaded rod; Both sides of the inner part of one of the movable grooves are jointly fixedly connected with a guiding rod, the outer surface of the guiding rod is slidably connected with a guiding block, and the left side of the guiding block is rotatably connected with one end of a rotating rod.

[0008] As a further solution of the utility model: One side of the inner part of one of the movable grooves is fixedly connected with a toothed plate, one side surface of the rotating rod is fixedly connected with a gear, and the gear is engaged with the toothed plate.

[0009] As a further solution of the utility model: The heat dissipation mechanism includes a heat conducting block, the heat conducting block is fixedly connected to one side of the top of the security camera body, a corresponding block is fixedly connected to the inner top end of the connection frame, and a blower is fixedly connected to one side of the connection frame.

[0010] As a further solution of the utility model: The opposite side surfaces of the heat conducting block and the corresponding block are designed with an arc protruding in the middle, and the heat conducting block is made of a heat-conducting metal material.

[0011] As a further solution of the utility model: The security camera body is electrically connected with a controller, and the controller is electrically connected with an alarm.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] For this linkage security camera, the motor is started by an external power supply. The motor drives the threaded rod to rotate, and the rotating threaded rod drives the moving block to move up and down, thereby driving the rotating rod to move in the same direction. Moreover, the rotating rod drives the guiding block to slide along the surface of the guiding rod, so as to achieve the effect of guiding during the rotation and movement. The rotating rod drives the cleaning roller to move in the same direction, and the inner surface of the cleaning roller is in contact with the detection end mirror surface of the security camera body, so as to achieve the cleaning effect on the detection end mirror surface of the security camera body. The cooperation of the above structures can not only efficiently clean the detection end of the security camera, but also prevent scratching the surface of the camera detection end.

[0014] In addition, for this linked security camera, an external power supply is used to start the fan. The air flow blown by the fan enters the opposite side of the heat conduction block and the corresponding block. Since the opposite side of the heat conduction block and the corresponding block is designed with a middle-convex arc shape, a ventilation duct with thick ends and a thin middle is formed on the opposite side of the heat conduction block and the corresponding block. When the air flow passes through this ventilation duct, it satisfies Bernoulli's principle (in water flow or air flow, if the speed is small, the pressure is high, and if the speed is large, the pressure is low). For the case pointed out by Bernoulli's principle, in the same air flow space, where the cross-section is small, the air speed is high; and where the cross-section is large, the air speed is low. Therefore, when the air flow blows into the ventilation duct on the opposite side of the heat conduction block and the corresponding block, the air flow will quickly pass through when it reaches the middle position, thus achieving the effect of quickly discharging the hot air in the ventilation duct. Furthermore, the effect of dissipating heat from the security camera body is achieved. Description of the Drawings

Detailed Embodiments

[0020] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application clearer, the following further details this application in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not used to limit this application.

[0021] As Figure 1 shown, a linked security camera includes a security camera body 10. The security camera body 10 is electrically connected to a controller 11, and the controller 11 is electrically connected to an alarm 12. A cleaning mechanism is provided at the top of the security camera body 10.

[0022] During use, the controller 11 starts the security camera body 10 through an external power supply. When the detection part of the started security camera body 10 detects a behavior that meets the preset conditions, it will feedback to the controller 11 and record the behavior through the built-in memory card. After receiving the feedback, the controller 11 will start the alarm 12 through the external power supply, and the alarm 12 will warn against this behavior, thus achieving the effect of device linkage.

[0023] Preferably, an installation bracket 13 is fixedly connected to the rear side of the bottom of the security camera body 10. During use, the security camera body 10 can be fixed at a higher position by connecting the installation bracket 13 to the wall with bolts. Since there are fewer covering objects at higher positions, the security camera body 10 can have a larger detection range.

[0024] Reference Figure 2 、 3 , the cleaning mechanism includes a connecting frame 20. The connecting frame 20 is in an inverted U shape, and the left and right sides inside the connecting frame 20 are fixedly connected to the left and right side surfaces of the security camera body 10. Activity slots 21 are opened on the left and right sides inside the connecting frame 20. A rotatable threaded rod 22 is rotatably connected to the upper and lower sides inside the left activity slot 21. A moving block 23 is threadedly connected to the threaded rod 22. A rotating rod 24 is rotatably connected to the right side of the moving block 23. A cleaning roller 25 is fixedly connected to the outer surface of the rotating rod 24.

[0025] Specifically, a motor 28 is fixedly connected to the left side of the top of the connecting frame 20, and the output end of the motor 28 is fixedly connected to the top end of the threaded rod 22. Guide rods 26 are fixedly connected to the upper and lower sides inside the right activity slot 21. A guide block 27 is slidably connected to the outer surface of the guide rod 26, and the left side of the guide block 27 is rotatably connected to the right end of the rotating rod 24. During use, the motor 28 is started through an external power supply. The motor 28 drives the threaded rod 22 to rotate. The rotating threaded rod 22 drives the moving block 23 to move up and down, driving the rotating rod 24 to move in the same direction. And the rotating rod 24 drives the guide block 27 to slide along the surface of the guide rod 26, achieving the effect of guiding the rotating rod 24 during movement. The rotating rod 24 drives the cleaning roller 25 to move in the same direction. The inner surface of the cleaning roller 25 is in contact with the detection end mirror surface of the security camera body 10, thus achieving the cleaning effect on the detection end mirror surface of the security camera body 10.

[0026] Preferably, the outer surface of the cleaning roller 25 is made of ultra-fine fiber cloth material. Thus, when the outer surface of the cleaning roller 25 comes into contact with the surface of the security camera body 10, it can wipe off the dust on the surface of the security camera body 10. And the ultra-fine fiber cloth is a soft and non-abrasive material that can safely wipe the camera surface without leaving scratches or fibers.

[0027] Preferably, a toothed plate 31 is fixedly connected to the inner rear side of the right movable slot 21, and a gear 30 is fixedly connected to the right surface of the rotating rod 24. The gear 30 meshes with the toothed plate 31. Thus, when the rotating rod 24 moves downward, it will drive the gear 30 to move downward. And because the gear 30 meshes with the toothed plate 31, the driving force pressing down on the gear 30 will cause the gear 30 to rotate counterclockwise along the surface of the toothed plate 31 (the direction of rotation here refers to Figure 4 ), thereby driving the rotating rod 24 and the cleaning roller 25 to rotate in the same direction. When the rotating cleaning roller 25 contacts the mirror surface of the security camera body 10, it can not only contact the mirror surface evenly and continuously, ensuring the comprehensiveness of the cleaning coverage, but also, through the rotational movement, the cleaning roller 25 can more effectively remove stains, dust and impurities on the mirror surface, improving the cleaning efficiency.

[0028] Since most of the security camera bodies 10 are installed outdoors, in summer, the temperature inside the security camera body 10 often rises due to the rising temperature or direct sunlight, affecting the use effect. Therefore, a heat dissipation mechanism is proposed.

[0029] Refer to Figure 4 , the heat dissipation mechanism includes a heat conducting block 40, the heat conducting block 40 is fixedly connected to the left side of the top of the security camera body 10, a corresponding block 41 is fixedly connected to the inner top end of the connecting frame 20, and a blower 42 is fixedly connected to the right side of the connecting frame 20.

[0030] Preferably, the opposite side surfaces of the heat conducting block 40 and the corresponding block 41 are designed with an arc protruding in the middle, and the heat conducting block 40 is made of a heat conducting metal material. During use, the heat conducting block 40 made of metal material will absorb the heat inside the security camera body 10 through heat transfer, and the heat dissipated by the security camera body 10 will also gather upward because hot air is less dense than air. Thus, the hot air will enter the opposite side of the heat conducting block 40 and the corresponding block 41. At the same time, the blower 42 is started by an external power supply, and the air flow blown out by the blower 42 enters the opposite side of the heat conducting block 40 and the corresponding block 41. And because the opposite side of the heat conducting block 40 and the corresponding block 41 is designed with an arc protruding in the middle, a ventilation duct with a thick middle and thin ends is formed on the opposite side of the heat conducting block 40 and the corresponding block 41. When the air flow passes through this ventilation duct, it satisfies Bernoulli's principle (in water flow or air flow, if the speed is small, the pressure is large, and if the speed is large, the pressure is small). And for the case pointed out by Bernoulli's principle, in the same space of the air flow, where the cross-section is small, the air speed is large; and where the cross-section is large, the air speed is small. Thus, when the air flow blows into the ventilation duct on the opposite side of the heat conducting block 40 and the corresponding block 41, the air flow will quickly pass through when it blows to the middle position, thereby achieving the effect of quickly discharging the hot air in the ventilation duct, and further achieving the effect of dissipating heat from the security camera body 10.

[0031] The working principle of the present utility model is as follows: The motor 28 is started through an external power supply. The motor 28 drives the threaded rod 22 to rotate. The rotating threaded rod 22 drives the moving block 23 to move up and down, thereby driving the rotating rod 24 to move in the same direction. And the rotating rod 24 drives the guiding block 27 to slide along the surface of the guiding rod 26, so as to achieve the effect of guiding the rotating rod 24 during movement. The rotating rod 24 drives the cleaning roller 25 to move in the same direction. The inner surface of the cleaning roller 25 is in contact with the detection end mirror surface of the security camera body 10, so as to achieve the cleaning effect on the detection end mirror surface of the security camera body 10.

[0032] The above shows and describes the basic principle, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
