Description

Technical Field

[0001] The utility model relates to the technical field of cameras, in particular to a security camera with a self-cleaning mechanism. Background Art

[0002] Security cameras need to be installed in tunnels for monitoring. However, the high dust and oil content in tunnels can easily adhere to the camera lens, resulting in blurred images. Currently, regular manual maintenance is the main method, which is costly. Roads must be closed during maintenance, affecting normal traffic. In addition, the lighting in tunnels is complex, with strong light and backlight at the tunnel entrance, reflected light and stray light in the middle of the tunnel, all of which will affect camera imaging. Therefore, a security camera with a self-cleaning mechanism is needed to meet the needs of high-definition imaging in tunnel scenes. Utility Model Content

[0022] like Figure 1 and Figure 2 As shown, a security camera with a self-cleaning mechanism includes a camera body 1 and a light shield 2. The light shield 2 is mounted on the front end of the camera body 1 and surrounds the periphery of the lens of the camera body 1. A nozzle 4 is mounted on the front end of the camera body 1. The water inlet of the nozzle 4 is connected to an external water supply device, and the water outlet of the nozzle 4 is directed toward the lens area of ​​the camera body 1.

[0023] The camera body 1 is provided with a protective door 3 on the outside, which can cover the light shield 2 and seal the opening of the light shield 2. A micro wiper 5 is installed on the inner side of the protective door 3 relative to the lens area of ​​the camera body 1. The reciprocating motion of the micro wiper 5 cleans the lens area.

[0024] The protective door 3 can be installed on the side of the light shield 2 through a sliding rail, and the opening of the light shield 2 can be closed by sliding. The protective door 3 can cover and close the opening of the light shield 2 by rotating, and the reciprocating motion of the micro wiper 5 belongs to the existing technology and will not be repeated here.

[0025] Specifically, if Figure 3-Figure 5 As shown, a micro motor 6 is installed on the front outer wall of the camera body 1, and a connecting plate 7 is installed on the output shaft of the micro motor 6. The end of the connecting plate 7 away from the micro motor 6 extends toward the front of the camera body 1 and is fixedly connected to the side of the protective door 3. The micro motor 6 drives the connecting plate 7 to rotate, so that the protective door 3 rotates and covers the opening of the light shield 2. The protective door 3 is driven to open and close by the micro motor 6, so that the opening of the light shield 2 is closed during self-cleaning operation and the opening of the light shield 2 is opened during security monitoring.

[0026] Furthermore, the micro motor 6 is mounted on the front side of the camera body 1, with the output shaft of the micro motor 6 facing upward and the axis thereof being perpendicular to the axis of the camera body 1. One end of the connecting plate 7 is fixedly mounted on the output shaft of the micro motor 6. This design enables the micro motor 6 located on the side of the camera body 1 to quickly drive the protective door 3 to rotate.

[0027] Furthermore, if Figure 1 and Figure 3 As shown, there are two protective doors 3 symmetrically distributed on both sides of the front end of the camera body 1. Each protective door 3 is driven by a micro motor 6 to realize a double-door design of the protective door 3, which better prevents the splashing of cleaning wastewater.

[0028] Furthermore, support plates are installed at the bottom of both sides of the front end of the camera body 1, and the other end of the support plates extends horizontally. Two micro motors 6 are respectively installed at the other ends of the two support plates. The output shafts of the micro motors 6 are set vertically upward. There are circuits inside the support plates, and the micro motors 6 are connected to the power supply inside the camera body 1 through the circuits.

[0029] Specifically, the micro wiper 5 includes a wiper motor, a wiper bone and a wiper blade. The wiper motor is installed on the inner side of the protective door 3 close to the camera body 1. One end of the wiper bone is connected to the output shaft of the wiper motor, and the other end of the wiper bone is installed with a wiper blade. When the protective door 3 covers and closes the opening of the light shield 2, the wiper blade fits against the front end surface of the camera body 1. The wiper motor drives the wiper bone to rotate back and forth, driving the wiper blade to scrub the lens area of ​​the camera body 1.

[0030] Specifically, if Figure 5 As shown, the external water supply device includes a water tank 8 installed at the bottom of the camera body 1 for storing cleaning liquid and a micro water pump integrated into the camera body 1. The micro water pump is connected to the inside of the water tank 8 through a water suction pipe, and the micro water pump is connected to the water inlet of the nozzle 4 through a drain pipe. The cleaning liquid in the water tank 8 is pumped by the micro water pump and supplied to the nozzle 4, and then sprayed out by the nozzle 4 to self-clean the lens area;

[0031] Furthermore, the bottom of the camera body 1 has a threaded opening, and the outer wall of the upper end of the water tank 8 has an external thread and is threadedly connected to the threaded opening, which facilitates the quick installation of the water tank 8. The upper end of the water tank 8 has a liquid inlet, and the liquid inlet is provided with a sealing plug. The middle of the sealing plug is provided with a small hole that passes through from top to bottom. The suction pipe of the micro water pump passes through the small hole and extends into the water tank 8, which facilitates the extraction of cleaning liquid.

[0032] Furthermore, a recovery box 9 is installed on the outside of the water tank 8, and a wastewater collection groove is provided at the bottom end of the inner wall of the light shield 2, and the bottom of the wastewater collection groove is connected to the top water inlet of the recovery box 9 through a return pipe 10. The wastewater is collected by the wastewater collection groove at the bottom end of the light shield 2, and the wastewater flows back to the recovery box 9 through the return pipe 10, completing the collection of the wastewater and avoiding the splashing and pollution of the cleaning wastewater, so as to recycle the cleaning wastewater and prevent spillage and pollution;

[0033] Furthermore, the recovery box 9 is detachably mounted on the side wall of the water tank 8 by means of a snap fastener, and the bottom end of the return pipe 10 is plugged into the water inlet of the recovery box 9, making it convenient for the recovery box 9 to be disassembled and assembled.

[0034] In summary, the utility model installs a protective door 3 at the front end of the camera body 1, uses the protective door 3 to close the front end opening of the light shield 2, and then supplies water to the nozzle 4 through an external water supply device, so that the nozzle 4 sprays water to the lens area at the front end of the camera body 1. Combined with the reciprocating wiping of the lens area by the micro wiper 5, the lens area can be self-cleaned. After cleaning, the protective door 3 opens outward and drives the micro wiper 5 to separate from the lens area, avoiding the impact of the normal monitoring period on the monitoring area, which is beneficial to improving the actual monitoring range. Moreover, during the self-cleaning time period, since the opening of the light shield 2 is closed, it can prevent the cleaning wastewater from splashing outward, thereby avoiding the wastewater from polluting the surrounding ground.
