Description

Technical Field

[0001] The present invention relates to the field of monitoring technologies, and specifically discloses a digital security monitoring device with an automatic cleaning function. Background Art

[0002] The monitoring system is one of the most widely used systems in the security system, and video monitoring is now the mainstream. From the earliest analog monitoring to the booming digital monitoring in the previous years and then to the emerging network video monitoring nowadays, earth-shaking changes have taken place. A digital security monitoring device refers to processing the images collected by digital security monitoring into digital signals through software and hardware and transmitting them to a computer for processing.

[0003] Chinese Patent No. CN218825255U discloses a digital security monitoring device, belonging to the field of monitoring technologies, including a load-bearing bracket and a digital security monitor. A support frame is fixedly connected to the right side of the load-bearing bracket near the top edge. After the monitoring device is used for a period of time, the extraction pump can be started to pump the cleaning liquid inside the liquid storage barrel into the placement box through the liquid extraction pipe. Starting the micro air pump can press the cleaning liquid to the cleaning spray gun for spraying, so that the cleaning spray gun can quickly clean the dust on the surface of the protective cover. The servo motor can drive the cleaning plate to rotate on the surface of the protective cover, so that the cleaning spray gun on the top of the cleaning plate can clean the dust on the surface of the protective cover during the rotation process. The cleaning cotton pad on the top of the cleaning plate can wipe the residual cleaning liquid, so that the surface of the protective cover remains clean. The staff only needs to add water to the inside of the liquid storage barrel to ensure that the monitoring device can automatically perform cleaning and nursing work, ensuring the monitoring effect of the monitoring device.

[0004] During the actual use of the above device, the stain is removed by driving a cleaning cloth or a brush to rotate and rub on the surface of the lens by a motor. The cleaning cloth is easy to adsorb dust in the air to form hard particles, which will damage the lens coating during scraping; the cleaning cloth needs to be replaced weekly and daily in high-dust scenarios such as mines, resulting in high operation and maintenance costs. Summary of the Invention

[0005] The present invention proposes a digital security monitoring device with an automatic cleaning function. Through the combined design of a scraper and a spray head, the device does not need to be frequently replaced, reduces the number of manual inspections and maintenance, eliminates secondary pollution sources, greatly reduces the operation and maintenance burden, and is especially suitable for monitoring scenarios in high-altitude, high-risk or remote areas.

[0006] The present invention is achieved as follows: a digital security monitoring device with an automatic cleaning function comprises a support column, an installation bin arranged inside the support column, an adjustable angle digital security monitoring body arranged above the outside of the support column through a bracket, and a camera lens embedded in one side of the digital security monitoring body, a rain cover is fixedly installed on the outside of the digital security monitoring body, a rotating shaft is arranged inside the rain cover and beside the camera lens; a rotating plate is fixedly installed on the top of the circumferential outer wall of the rotating shaft, and a scraper made of silicone is fixedly installed on the side of the rotating plate close to the digital security monitoring body; a spray chamber located above the camera lens is fixedly installed on one side of the digital security monitoring body, a plurality of nozzles with ports facing the camera lens are connected at the bottom of the spray chamber, and a connecting pipe extending to the outside of the rain cover is connected at the top of the spray chamber.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following will further illustrate the present invention in conjunction with the drawings and specific embodiments to help understand the content of the present invention. The methods used in the present invention are all conventional methods unless otherwise specified; the raw materials and devices used are all conventional commercially available products unless otherwise specified.

[0023] Please refer toFigures 1-4 A digital security monitoring device with an automatic cleaning function comprises a support column 1, an installation bin 101 arranged inside the support column 1, an adjustable angle digital security monitoring body 3 arranged above the outside of the support column 1 through a bracket 2, and a camera lens 301 embedded in one side of the digital security monitoring body 3, a rain cover 4 is fixedly installed on the outside of the digital security monitoring body 3, a rotating shaft 401 is arranged inside the rain cover 4 and beside the camera lens 301; a rotating plate 402 is fixedly installed on the top of the circumferential outer wall of the rotating shaft 401, and a scraper 403 made of silicone material is fixedly installed on one side of the rotating plate 402 close to the digital security monitoring body 3; a spray chamber 5 located above the camera lens 301 is fixedly installed on one side of the digital security monitoring body 3, a nozzle 501 with multiple ports arranged facing the camera lens 301 is connected at the bottom of the spray chamber 5, and a connecting pipe 502 extending to the outside of the rain cover 4 is connected at the top of the spray chamber 5.

[0024] In this embodiment: cleaning liquid (such as water or special solution) is introduced into the spray chamber 5 from the water tank 7 and the water pump 8 through the connecting pipe 502, and evenly covers the lens surface after being atomized by the nozzle 501, softening stubborn stains such as oil and mud, reducing the wiping resistance of the scraper 403, and improving the cleaning effect. By driving the rotating shaft 401 to rotate, the rotating plate 402 is driven to make an arc motion, so that the scraper 403 slides closely against the surface of the camera lens 301, and solid stains such as dust, particles, and bird droppings on the lens surface are removed through physical contact. The device replaces the traditional cleaning cloth with a silicone scraper 403 to eliminate secondary pollution sources.

[0025] As a technical optimization scheme of the present invention, a driving chamber 6 is opened inside the digital security monitoring body 3, one end of the rotating shaft 401 extends to the interior of the driving chamber 6 and is rotatably connected to the inner wall of the driving chamber 6, a worm gear 601 is fixedly installed on the outside of a circle of the rotating shaft 401 located inside the driving chamber 6, the outer wall of the worm gear 601 is meshingly connected to a worm 602, a stepper motor 604 is fixedly installed on the outer wall of the digital security monitoring body 3, and the output end of the stepper motor 604 is coaxially fixedly connected to the worm 602.

[0026] In this embodiment: the drive chamber 6 is an independent cavity inside the digital security monitoring body 3, the worm wheel 601 and the worm 602 are in a vertical meshing state (the axis of the worm and the axis of the worm wheel are vertically staggered), and the stepper motor 604 is started to drive the worm 602 to rotate. The worm 602 drives the worm wheel 601 to rotate through the tooth surface meshing, and then drives the rotating shaft 401 to rotate, so that the scraper 403 makes a circular motion around the rotating shaft 401 to clean the camera lens 301. The high-precision positioning characteristics of the stepper motor 604 can accurately control the rotation angle of the scraper 403 (such as 90-degree rotation). When the scraper 403 rotates, its length can cover the entire camera lens 301, and cooperate with the water spraying action of the spray chamber 5 to achieve automatic and dead-angle cleaning.

[0027] As a technical optimization solution of the present invention, the outer wall of the stepper motor 604 is provided with a protective box 603 which is fixedly mounted on the outer wall of the digital security monitoring body 3 and has an open bottom.

[0028] In this embodiment: the protective box 603 is made of metal or high-strength plastic material, and is fixed to the outer wall of the digital security monitoring body 3 by bolts, completely covering the stepper motor 604, leaving only the bottom open, which can not only effectively block rainwater, but also ensure that the heat generated during the operation of the stepper motor 604 is dissipated through the bottom opening, avoiding the impact of heat accumulation on the motor performance and service life, and improving the stability and reliability of the equipment operation.

[0029] As a technical optimization solution of the present invention, a water tank 7 with a water inlet pipe and a sealing cover is fixedly installed inside the installation bin 101, and a liquid level meter 701 is arranged on the top of the water tank 7, and the sensor of the liquid level meter 701 extends to the inside of the water tank 7.

[0030] In this embodiment: the water inlet pipe is used to add clean water or cleaning liquid to the water tank 7, the sealing cover ensures the sealing of the water inlet pipe to prevent liquid leakage and impurities from entering, and the liquid level meter 701 monitors the liquid level height in the water tank 7 in real time.

[0031] As a technical optimization solution of the present invention, a water pump 8 is fixedly installed on the top of the water tank 7, the input end of the water pump 8 is connected to a pipe extending into the inside of the water tank 7, and the output end of the water pump 8 is connected to the connecting pipe 502 through the pipe.

[0032] In this embodiment: when the camera lens 301 needs to be cleaned, the water pump 8 is started, and the cleaning liquid or clean water in the water tank 7 is pumped out through the pipe at the input end, and then transported to the spray chamber 5 through the pipe at the output end and the connecting pipe 502, and finally sprayed to the camera lens 301 by the nozzle 501.

[0033] As a technical optimization solution of the present invention, a door panel 102 with a door lock is hinged on the port of the installation compartment 101.

[0034] In this embodiment: the door lock adopts a lock with good anti-theft performance. When it is necessary to maintain, inspect or replenish liquid for the water tank 7, water pump 8 and other equipment in the installation chamber 101, the door lock can be opened and the door panel 102 can be easily opened, which is convenient for the staff to operate; after closing and locking the door panel 102, it can effectively prevent unauthorized personnel from contacting the equipment in the installation chamber 101 at will, and at the same time play a role in dustproof, waterproof and anti-theft, ensuring the safety of the equipment and normal operating environment.

[0035] As a technical optimization solution of the present invention, the bottom end surface inside the rain cover 4 is inclined toward the port.

[0036] In this embodiment: The sewage after cleaning the camera lens 301 falls on the bottom inside the rain shield 4 and is discharged along its bottom.

[0037] The working principle and usage process of the present invention: This device is connected to the cloud server using a wireless communication module (not shown in the figure) and a PLC controller. The wireless communication module integrates 4G and Wi-Fi dual-mode chips and has a built-in encryption chip (such as ATECC608A), which can receive remote instructions and control the start and stop of the water pump 8 and the stepping motor 604 through the PLC controller, and upload data such as the liquid level to the cloud in real time. When cleaning the camera lens 301, the water pump 8 extracts the cleaning liquid (or water) from the water tank 7 and transports it to the spraying chamber 5 through the connecting pipe 502. Multiple nozzles 501 at the bottom of the spraying chamber 5 evenly spray the liquid onto the surface of the camera lens 301 to dissolve or wash away the attached stains (such as dust and rain stains). At this time, the stepping motor 604 drives the worm 602 to rotate. The worm 602 meshes with the worm gear 601 to drive the rotating shaft 401 to rotate slowly (the reduction ratio is determined by the parameters of the worm and worm gear). The rotating plate 402 fixed to the top of the rotating shaft 401 rotates with the shaft, driving the scraper 403 to rotate. When the scraper 403 rotates, it can fit the camera lens 301, so that the scraper 403 scrapes along the surface of the camera lens 301 in an arc trajectory to remove the residual liquid and stubborn stains.
