Detailed Description of the Embodiments

[0022] In order to make the technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0023] The present invention provides a technical solution: Refer to Figure 1 - Figure 5, a video surveillance device for building security disclosed by the utility model includes a connecting plate 1, a transparent cover 2 and a video surveillance device body. The video surveillance device body is fixedly installed at the center position of the bottom side of the connecting plate 1. The transparent cover 2 is sleeved on the outer peripheral side of the video surveillance device body. The top end of the transparent cover 2 is inserted into the connecting plate 1 and rotatably connected with the connecting plate 1 through a bearing. A cleaning component 3 is arranged on the transparent cover 2. The cleaning component 3 includes a scraping plate 31. The scraping plate 31 is arranged on the outer peripheral side of the transparent cover 2 and is in contact with the outer wall of the transparent cover 2. One end of the scraping plate 31 is fixedly connected with the connecting plate 1 through a bolt. A driving mechanism 33 is arranged on the top side of the transparent cover 2, and a guiding mechanism 4 is arranged on the bottom side of the driving mechanism 33.

[0024] In this embodiment, when the improved video surveillance device for building security is in use, the driving mechanism 33 continuously drives the transparent cover 2 to rotate. As the scraping plate 31 rotates, the scraping plate 31 slides along the outer wall of the transparent cover 2, thereby gradually scraping off the sundries attached to the outer wall of the transparent cover 2 to prevent a large amount of sundries from attaching to the outer wall of the transparent cover 2 and affecting the use of the video surveillance device. At the same time, the driving mechanism 33 drives the guiding mechanism 4 to operate, continuously extracting the gas in the transparent cover 2 and discharging it from the outer peripheral side of the transparent cover 2. Furthermore, a continuous air flow can be formed on the outer peripheral side of the transparent cover 2, pushing the scraped sundries away from the transparent cover 2 and preventing the obstacles on the outer peripheral side from floating towards the video surveillance device and blocking the video surveillance device, affecting the use of the video surveillance device. At the same time, the negative pressure cavity in the transparent cover 2 continuously sucks the external gas into the transparent cover 2 through the guiding mechanism 4 to accelerate the gas exchange inside and outside the transparent cover 2, preventing a large temperature difference from being generated inside and outside the transparent cover 2 due to the heat dissipated by the video surveillance device when it is used in a relatively cold environment, and forming water mist on the outer wall of the transparent cover 2, affecting the use of the video surveillance device. At the same time, during the use of the device, there is only one component, the scraping plate 31, on the outer peripheral side of the transparent cover 2. When installing the device, making the scraping plate 31 face the blind spot monitored by the video surveillance device can avoid the scraping plate 31 blocking the video surveillance device and affecting the use of the video surveillance device.

[0025] In a further preferred embodiment of the utility model, as Figure 2 shown, the driving mechanism 33 includes a motor 333. A storage groove 331 is formed on the top side of the connecting plate 1. A rectangular groove 332 is formed on the outer peripheral wall of the top side of the connecting plate 1, and the inside of the rectangular groove 332 is communicated with the inside of the storage groove 331. The motor 333 is fixedly installed in the storage groove 331;

[0026] In this embodiment, the setting of the storage groove 331 makes the motor 333 directly exposed outside the connecting plate 1, facilitating the maintenance and replacement of the motor 333. And the setting of the rectangular groove 332 leaves space for the installation of external lines.

[0027] In a further preferred embodiment of the utility model, as Figure 2 andFigure 5 As shown, an annular groove 334 is formed in the connecting plate 1. A toothed ring 335 is arranged in the annular groove 334. The top end of the transparent cover 2 is inserted into the annular groove 334 and fixedly connected to the bottom side of the toothed ring 335. A plurality of gears 336 are meshed and arranged in a circumferential array on the outer peripheral side of the toothed ring 335, and each gear 336 is rotatably connected to the connecting plate 1. The driving end of the motor 333 is fixedly connected to the top side of the corresponding gear 336;

[0028] In this embodiment, when the above-mentioned video surveillance device for building security is in use, the motor 333 starts to drive the gear 336 to rotate rapidly, thereby slowly driving the transparent cover 2 to rotate through the toothed ring 335. During the rotation of the transparent cover 2, the scraper 31 slides along the outer wall of the transparent cover 2, thereby scraping off the sundries attached to the outer wall of the transparent cover 2. Since the cover wall of the transparent cover 2 is transparent, the rotation of the transparent cover 2 hardly affects the shooting of the video surveillance device.

[0029] In a further preferred embodiment of the present utility model, as Figure 2 shown, the diversion mechanism 4 includes a filter plate 41. The filter plate 41 is fixedly installed through the bottom end of the transparent cover 2. The filter plate 41 is fixedly connected to the other end of the scraper 31 through a connecting rod;

[0030] In this embodiment, when the above-mentioned external air flows into the transparent cover 2, it needs to pass through the holes of the filter plate, thereby blocking the sundries in the external gas outside the transparent cover 2 and preventing the external sundries from floating into the transparent cover 2 and affecting the transparency of the transparent cover 2;

[0031] The arrangement of the filter plate 41 and the connecting rod can restrict and limit the other end of the scraper 31, so that the scraper 31 is stably attached to the transparent cover 2.

[0032] In a further preferred embodiment of the present utility model, as Figure 2 - Figure 5 shown, a plurality of connecting holes 42 are formed in the inner bottom side of the annular groove 334, and the plurality of connecting holes 42 are arranged in a circumferential array inside the transparent cover 2. Circular grooves 43 are formed at the bottom side of the annular groove 334 corresponding to the positions of the gears 336. Impellers 44 are arranged in the circular grooves 43, and the top ends of the impellers 44 are fixedly connected to the corresponding gears 336;

[0033] In this embodiment, during the rapid rotation of the above-mentioned gear 336, the impeller 44 is continuously driven to rotate, continuously pushing the gas in the circular groove 43 outside the circular groove 43 and continuously sucking the gas inside the transparent cover 2 through the annular groove 334 and the connecting holes 42 to supplement the gas lost in the circular groove 43, so that a negative pressure cavity is continuously formed inside the transparent cover 2. At this time, a pressure difference is continuously formed on both sides of the filter plate 41, and the external gas continuously flows into the transparent cover 2 through the holes of the filter plate 41, and no additional power source needs to be set, reducing the energy consumption during the use of the device.

[0034] In a further preferred embodiment of the present utility model, as Figure 2 - Figure 4 shown, a diversion groove 45 with an annular shape is formed at a position corresponding to the circular groove 43 inside the connecting plate 1, and the diversion groove 45 is located at the bottom end of a plurality of circular grooves 43 and communicates with the inside of the plurality of circular grooves 43. A plurality of exhaust holes 46 are formed on the inner bottom side of the diversion groove 45, and the plurality of exhaust holes 46 are arranged in a circumferential array on the outer peripheral side of the transparent cover 2;

[0035] In this embodiment, the gas flowing out of the circular groove 43 directly flows into the annular groove 334. Since the amount of gas discharged from the exhaust hole 46 is limited, the gas pushed into the diversion groove 45 first fills the diversion groove 45 and then is synchronously discharged from the plurality of exhaust holes 46. At the same time, due to the pressure difference at both ends of the exhaust hole 46, the air flow discharged from the exhaust hole 46 is discharged relatively quickly, thereby pushing the obstacles on the outer peripheral side of the transparent cover 2 to move away and pushing the sundries scraped off the transparent cover 2 in a direction away from the transparent cover 2.

[0036] Working principle: When the improved video surveillance device for building security is in use, the motor 333 starts to drive the gear 336 to rotate rapidly, thereby slowly driving the transparent cover 2 to rotate through the toothed ring 335. During the rotation of the transparent cover 2, the scraper 31 slides along the outer wall of the transparent cover 2, thereby scraping off the sundries attached to the outer wall of the transparent cover 2;

[0037] During the rotation of the gear 336, the impeller 44 can be driven to rotate continuously, thereby continuously pushing the gas in the circular groove 43 into the diversion groove 45. Since the amount of gas discharged from the exhaust hole 46 is limited, the gas pushed into the diversion groove 45 first fills the diversion groove 45 and then is synchronously discharged from the plurality of exhaust holes 46. At the same time, due to the pressure difference at both ends of the exhaust hole 46, the air flow discharged from the exhaust hole 46 is discharged relatively quickly, thereby pushing the obstacles on the outer peripheral side of the transparent cover 2 to move away and pushing the sundries scraped off the transparent cover 2 in a direction away from the transparent cover 2;

[0038] As the gas in the circular groove 43 continuously flows out, a negative pressure cavity is continuously formed in the circular groove 43, and then the gas in the transparent cover 2 is continuously sucked through the annular groove 334 and the connection hole 42 to supplement the gas lost in the circular groove 43. At the same time, a negative pressure cavity is continuously formed in the transparent cover 2. At this time, the outside air continuously flows into the transparent cover 2 through the holes of the filter plate 41 to supplement the gas lost in the transparent cover 2, and the dust in the gas is blocked outside the transparent cover 2 by the filter plate 41, thereby adjusting the temperature difference between the inside and outside of the transparent cover 2 through the gas exchange between the inside and outside of the transparent cover 2 and avoiding the formation of water mist on the outer wall of the transparent cover 2 due to a large temperature difference between the inside and outside of the transparent cover 2, which affects the use of the device.

Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present utility model.
