Description
Technical Field
[0001] The invention belongs to the technical field of security equipment and relates to a security camera, in particular to a security camera with an automatic cleaning function. Background Art
[0002] Security cameras are used for security video surveillance. They convert the light images on the target surface of the image sensor from visible light to near-infrared spectrum into video image signals. Currently, most of the components on the market are CCD components, and there are a few CMOS components. CCD components are essentially what we call photoelectric conversion components. Their job is to convert the camera's vision of the monitored area into electrical signals and send them to other related products, and finally present them to people in the form of pictures. With the rapid development of science and technology, CCD components are already ten times more sensitive than CMOS components, which allows people to see clearer and clearer pictures.
[0003] Existing security cameras are divided into many types according to different usage environments. When the camera is used in a dusty environment, dust particles are easily attached to the lens, resulting in blurred camera images and poor shooting effects. Maintenance personnel are required to clean the lens frequently, and repeated wiping of the lens may cause scratches on the lens, which is not conducive to the long-term use of the camera.
[0004] Based on this, we designed a security camera with automatic cleaning function. Summary of the invention
[0005] The purpose of the present invention is to address the above-mentioned problems in the existing technology and to propose a security camera with an automatic cleaning function. The technical problem to be solved by the device is: how to realize the automatic cleaning function of the security camera and improve the shooting effect.
[0006] The purpose of the present invention can be achieved by the following technical solutions:
[0007] A security camera with an automatic cleaning function comprises a camera body, wherein the rear side of the camera body is hinged with a base, a single lens is arranged at the front end of the camera body, two symmetrically distributed long grooves are provided on the front end surface of the camera body, and the two long grooves are respectively located on both sides of the single lens, a clamping mechanism is provided at the front end of the camera body for fixing the single lens, a protective cover is fixed at the upper end of the camera body, a cleaning mechanism is provided at the front end of the protective cover for scraping off dust attached to the outer side of the single lens, a casing is fixed between the protective cover and the camera body, a blowing mechanism is provided in the casing, and the blowing mechanism is transmission-connected to the cleaning mechanism, and one end of the casing away from the front end of the camera body is connected to two symmetrically distributed connecting pipes, and the ends of the connecting pipes are connected to a blowing pipe, the blowing pipe is located in the long groove, and a plurality of blowing holes are provided on the side wall of the blowing pipe.
[0008] The working principle of the present invention is as follows: The single lens is fixed at the front end of the camera body through a clamping mechanism to protect the lens of the camera body, so that dust falls on the outside of the single lens. Then, the cleaning mechanism clears the dust on the single lens at regular intervals. After the cleaning mechanism finishes clearing the dust, the air blowing mechanism moves in the housing, generates an air flow, and blows air to the cleaning mechanism through the connecting pipe and the blowing pipe to blow away the dust scraped off by the cleaning mechanism, ensuring the continuous cleaning effect of the cleaning mechanism.
[0009] The clamping mechanism includes a clamping strip, two clamping blocks and a sealing ring. The clamping strip is fixed above the front end face of the camera body. Two symmetrically distributed sliding grooves are opened below the front end face of the camera body, and sliders are slidably arranged in the sliding grooves. The two clamping blocks are respectively fixed on the two sliders, and an inclined surface is opened at the side end of the clamping block. The single lens is clamped between the clamping strip and the clamping blocks. The sealing ring is fixed on the front end face of the camera body, the sealing ring abuts against the edge of the single lens, and a heating wire is fixed inside the sealing ring.
[0010] With the above structure, by sliding the two clamping blocks along the sliding grooves, the clamping blocks can be separated from the single lens on both sides, so that the single lens can be taken out from below the clamping strip for replacement, which is convenient for replacing the scratched single lens and ensures the long-term use of the camera body. Moreover, the inclined surface makes it more smooth and convenient for the operator to install the single lens, and heating can ensure that the single lens will not frost or fog, ensuring the imaging effect.
[0011] The cleaning mechanism includes a micro motor, a threaded rod, a moving block, a moving rod and a limiting frame. The micro motor is fixed on one side of the protective cover, the threaded rod is fixedly connected to the output shaft of the micro motor, and the other end of the threaded rod is rotatably connected to the other side of the protective cover. The moving block is threadedly connected to the threaded rod, and the moving rod is vertically fixed on the moving block. The limiting frame is fixed inside the protective cover, and the upper end of the moving rod is slidably arranged in the limiting frame. A scraping strip is fixed on the side end of the moving rod.
[0012] With the above structure, the micro motor drives the threaded rod to rotate. Under the limiting action of the limiting frame, the moving rod and the moving block cannot rotate. Therefore, the moving block and the moving rod move along the threaded rod, and the outer side of the single lens is scraped by the scraping strip to ensure the cleanliness of the single lens and the imaging quality.
[0013] The cam is secured to the piston with a spring which is fixed to one end of the piston and has a V-shaped groove on the connecting plate. Two parallel cross bars are fixed on the front end of the housing. The pull rod is slidably arranged on the two cross bars, and two clamping rods are fixed on one end of the pull rod. A roller is rotatably arranged at the end of the clamping rod away from the pull rod, and the roller is located inside the V-shaped groove. A sliding hole is provided at the other end of the pull rod, and a sliding rod is slidably inserted in the sliding hole. A toggle block is fixed on the end of the slide rod, and two symmetrically distributed triangular blocks are fixed on both sides of the toggle block. A long slot is provided on one side wall of the limit frame, and the toggle block passes through the long slot. A spring is sleeved on the outside of the slide rod, and two ends of the spring are respectively against the toggle block and the pull rod, and two limit rods matching the triangular block are fixed inside the housing.
[0014] With the above structure, when the moving rod moves in the limit frame, it will drive the toggle block to move to one side. While the toggle block moves, the pull rod and the toggle block move synchronously, and at the same time, the roller is driven to move through the clamping rod. Under the action of the V-shaped groove, the connecting plate and the piston are pulled toward the front end, so that the tension spring is lengthened until the triangular block contacts one of the limit rods. Under the action of the limit rod, the triangular block drives the toggle block to move in the direction close to the pull rod, and the toggle block is separated from the moving rod. At this time, under the maximum use of the tension spring, the piston is reset and drives the pull rod to reset through the V-shaped groove. During the resetting process of the piston, the air at the rear end of the housing will be squeezed out through the connecting pipe, and the air will be blown to the scraper strip through the blowing pipe to blow off the dust on the scraper strip, thereby ensuring the cleaning effect of the scraper strip when it is cleaned next time.
[0015] The blowing mechanism also includes two sealing boxes, two air blocking plates and a connecting rod. The two sealing boxes are respectively fixed at symmetrical positions on the outer side of the casing. The connecting pipe consists of two sections, and the two parts of the connecting pipe are connected to the side walls of the sealing box. The two parts of the connecting pipe are connected to the interior of the sealing box. The air blocking plate is slidably arranged inside the sealing box, and one end of the air blocking plate passes through the side wall of the casing and extends to the interior of the casing. A through hole is opened on the air blocking plate. Two clamps are fixed inside the casing, and the connecting rod is slidably arranged in the two clamps. The two ends of the connecting rod are respectively fixedly connected to the air blocking plates at corresponding positions.
[0016] With the above structure, when the pull rod moves to one side, it will push the wind block plate on that side to move, so that the through hole is aligned with the connecting pipe. At this time, the connecting pipe on this side is connected, and under the action of the connecting rod, the wind block plate on the other side will move toward that side for a while, so that the through hole and the connecting pipe are separated. At this time, the connecting pipe on the other side is blocked, so that the airflow generated by the blowing mechanism is all blown out through the connecting pipe on this side and the blowing pipe on this side, ensuring that the wind force acts on the scraper bar in full, thereby improving the cleaning effect. Similarly, when the pull rod moves to the other side, the connecting pipe on the other side is connected, and the wind force acts on the scraper bar in full.
[0017] One end of the wind blocking plate located inside the housing is fixed with a spring gasket, and an extrusion block is fixed at the end of the spring gasket.
[0018] With the above structure, when the pull rod pushes the wind blocking plate and pushes the wind blocking plate to the outermost side, when the triangular block and the limit rod are worn, the moving distance of the pull rod to both sides changes greatly. At this time, after the wind blocking plate moves to the outermost side, the pull rod will compress the spring gasket, so that the pull rod can still move and the device will not be stuck, improving the actual use effect.
[0019] Compared with the prior art, the security camera with an automatic cleaning function has the following advantages:
[0020] The single lens is fixed by the clamping mechanism, which is convenient for replacing the worn or scratched single lens and facilitating the long-term use of the camera body;
[0021] Through the cleaning mechanism, the dust outside the single lens is automatically scraped off, improving the imaging clarity of the camera body;
[0022] Through the housing, the air blowing mechanism, the connecting pipe and the air blowing pipe, air flow is generated and the air flow is controlled to blow towards the scraping strip to clean the scraping strip and ensure its subsequent scraping effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] Please refer to Figures 1-11 , this embodiment provides a security camera with an automatic cleaning function, including a camera body 1. A base 2 is hinged to the rear side of the camera body 1. A single lens 3 is provided at the front end of the camera body 1. Two symmetrically distributed long slots 101 are formed on the front end face of the camera body 1, and the two long slots 101 are respectively located on both sides of the single lens 3. A clamping mechanism 4 is provided at the front end of the camera body 1 for fixing the single lens 3. A protective cover 5 is fixed to the upper end of the camera body 1. A cleaning mechanism 6 is provided at the front end of the protective cover 5 for scraping off the dust attached to the outside of the single lens 3. A housing 7 is fixed between the protective cover 5 and the camera body 1. A blowing mechanism 8 is provided in the housing 7, and the blowing mechanism 8 is in transmission connection with the cleaning mechanism 6. Two symmetrically distributed connecting pipes 9 are connected to one end of the housing 7 away from the front end of the camera body 1, and the end of the connecting pipe 9 is connected to a blowing pipe 10. The blowing pipe 10 is located in the long slot 101, and a plurality of blowing holes are formed on the side wall of the blowing pipe 10; the single lens 3 is fixed to the front end of the camera body 1 through the clamping mechanism 4 to protect the lens of the camera body 1, so that dust falls on the outside of the single lens 3. Then, the cleaning mechanism 6 clears the dust on the single lens 3 at regular intervals. After the cleaning mechanism 6 finishes clearing the dust, the blowing mechanism 8 moves in the housing 7 to generate an air flow and blow air to the cleaning mechanism 6 through the connecting pipe 9 and the blowing pipe 10 to blow away the dust scraped off by the cleaning mechanism 6, ensuring the continuous cleaning effect of the cleaning mechanism 6.
[0040] The clamping mechanism 4 includes a clamping strip 401, two clamping blocks 404 and a sealing ring 406. The clamping strip 401 is fixed above the front end face of the camera body 1. Two symmetrically distributed sliding grooves 402 are formed below the front end face of the camera body 1, and sliders 403 are slidably arranged in the sliding grooves 402. The two clamping blocks 404 are respectively fixed on the two sliders 403, and an inclined surface 405 is formed at the side end of the clamping block 404. The single-piece lens 3 is clamped between the clamping strip 401 and the clamping blocks 404. The sealing ring 406 is fixed on the front end face of the camera body 1. The sealing ring 406 abuts against the edge of the single-piece lens 3, and a heating wire 407 is fixed inside the sealing ring 406. By sliding the two clamping blocks 404 along the sliding grooves 402, the clamping blocks 404 can be separated from the single-piece lens 3 on both sides, so that the single-piece lens 3 can be taken out from below the clamping strip 401 for replacement, which is convenient for replacing the scratched single-piece lens 3, ensuring the long-term use of the camera body 1. Moreover, the inclined surface 405 makes it more smooth and convenient for the operator to install the single-piece lens 3. In addition, heating can ensure that the single-piece lens 3 will not frost or fog, ensuring the imaging effect.
[0041] The cleaning mechanism 6 includes a micro motor 601, a threaded rod 602, a moving block 603, a moving rod 604 and a limiting frame 606. The micro motor 601 is fixed on one side of the protective cover 5. The threaded rod 602 is fixedly connected to the output shaft of the micro motor 601, and the other end of the threaded rod 602 is rotatably connected to the other side of the protective cover 5. The moving block 603 is threadedly connected to the threaded rod 602, and the moving rod 604 is vertically fixed on the moving block 603. The limiting frame 606 is fixed inside the protective cover 5, and the upper end of the moving rod 604 is slidably arranged in the limiting frame 606. A scraping strip 605 is fixed on the side end of the moving rod 604. The micro motor 601 drives the threaded rod 602 to rotate. Under the limiting action of the limiting frame 606, the moving rod 604 and the moving block 603 cannot rotate. Therefore, the moving block 603 and the moving rod 604 move along the threaded rod 602, and the outer side of the single-piece lens 3 is scraped by the scraping strip 605 to ensure the cleanliness of the single-piece lens 3 and the imaging quality.
[0042] The blowing mechanism 8 includes a piston 801, a connecting plate 802 and a pull rod 805. The piston 801 is slidably arranged inside the casing 7, and a tension spring 808 is fixed to one side wall of the piston 801, and the end of the tension spring 808 is fixedly connected to the inner wall of the casing 7. The connecting plate 802 is fixedly connected to the piston 801, and a V-shaped groove 803 is provided on the connecting plate 802. Two parallel cross bars 804 are fixed to the front end of the casing 7. The pull rod 805 is slidably arranged on the two cross bars 804, and two clamping rods 806 are fixed to one end of the pull rod 805. The clamping rod 806 is fixed to the inner wall of the casing 7. 06 A roller 807 is rotatably arranged at one end away from the pull rod 805, and the roller 807 is located inside the V-shaped groove 803. A sliding hole is provided at the other end of the pull rod 805, and a sliding rod 809 is slidably inserted in the sliding hole. A toggle block 810 is fixed to the end of the sliding rod 809, and two symmetrically distributed triangular blocks 812 are fixed on both sides of the toggle block 810. A long slot 607 is provided on one side wall of the limit frame 606, and the toggle block 810 passes through the long slot 607. A spring 811 is sleeved on the outer side of the sliding rod 809, and the two ends of the spring 811 are respectively engaged with the toggle block 810 and the pull rod 805 are against each other, and two limit rods 813 matching the triangular block 812 are fixed inside the housing 7; when the moving rod 604 moves in the limit frame 606, it will drive the toggle block 810 to move to one side, and when the toggle block 810 moves, the pull rod 805 moves synchronously with the toggle block 810, and at the same time, the roller 807 is driven to move through the clamping rod 806, and under the action of the V-shaped groove 803, the connecting plate 802 and the piston 801 are pulled to the front end, so that the tension spring 808 is stretched until the triangular block 812 is in contact with one of the limit rods 813. Contact, under the action of the limit rod 813, the triangular block 812 drives the toggle block 810 to move towards the direction close to the pull rod 805, and makes the toggle block 810 disengage from the moving rod 604. At this time, under the maximum use of the tension spring 808, the piston 801 is reset and drives the pull rod 805 to reset through the V-shaped groove 803. In the process of resetting the piston 801, the air at the rear end of the shell 7 will be squeezed out through the connecting pipe 9, and blown to the scraper 605 through the blowing pipe 10, so as to blow off the dust on the scraper 605 and ensure the cleaning effect of the scraper 605 when it is cleaned next time.
[0043] The blowing mechanism 8 also includes two sealing boxes 814, two air blocking plates 815 and a connecting rod 817. The two sealing boxes 814 are respectively fixed at symmetrical positions on the outer side of the casing 7. The connecting pipe 9 is composed of two sections, and the two parts of the connecting pipe 9 are connected to the side walls of the sealing box 814. The two parts of the connecting pipe 9 are communicated with the inside of the sealing box 814. The air blocking plate 815 is slidably arranged inside the sealing box 814, and one end of the air blocking plate 815 penetrates the side wall of the casing 7 and extends to the inside of the casing 7. A through hole 816 is opened on the air blocking plate 815. Two clamps 818 are fixed inside the casing 7, and the connecting rod 817 is slidably arranged in the two clamps 818. The two ends of the connecting rod 817 are respectively connected to the opposite sides. The air baffle plate 815 at the corresponding position is fixedly connected; when the pull rod 805 moves to one side, it will push the air baffle plate 815 on that side to move, so that the through hole 816 is aligned with the connecting pipe 9. At this time, the connecting pipe 9 on this side is connected. Under the action of the connecting rod 817, the air baffle plate 815 on the other side moves toward that side for a while, so that the through hole 816 and the connecting pipe 9 are separated. At this time, the connecting pipe 9 on the other side is blocked, so that the airflow generated by the blowing mechanism 8 is all blown out through the connecting pipe 9 on this side and the blowing pipe 10 on this side, ensuring that the wind force acts on the scraper 605 in full, thereby improving the cleaning effect. Similarly, when the pull rod 805 moves to the other side, the connecting pipe 9 on the other side is connected, and the wind force acts on the scraper 605 in full.
[0044] A spring gasket is fixed to one end of the air blocking plate 815 located inside the casing 7, and an extrusion block 819 is fixed to the end of the spring gasket; when the pull rod 805 pushes the air blocking plate 815, it pushes the air blocking plate 815 to the outermost side. When the triangular block 812 and the limiting rod 813 are worn, the moving distance of the pull rod 805 to both sides changes greatly. At this time, after the air blocking plate 815 moves to the outermost side, the pull rod 805 will compress the spring gasket, so that the pull rod 805 can still move, and will not cause the device to get stuck, thereby improving the actual use effect.
[0045] The above-mentioned fixing methods are the most commonly used fixing connection methods in this field, such as welding, bolt connection, etc.; the above-mentioned electrical components, such as the camera body 1 and the micro motor 601, etc., are all existing technology products and can be directly purchased and used in the market, and the specific principles will not be repeated.
[0046] Working principle of the present invention:
[0047] The single lens 3 is fixed to the front end of the camera body 1 by the clamping mechanism 4, and the two clamping blocks 404 are slid along the slide groove 402, so that the clamping blocks 404 can be separated from the single lens 3 to both sides, so that the single lens 3 can be taken out from under the clamping strip 401 for replacement, which is convenient for replacing the scratched single lens 3 and ensures the long-term use of the camera body 1. In addition, the inclined surface 405 makes it smoother and more convenient for operators to install the single lens 3. Dust falls on the outside of the single lens 3. At regular intervals, the micro motor 601 drives the threaded rod 602 to rotate. Under the limiting action of the limiting frame 606, the moving rod 604 and the moving block 603 cannot rotate, so the moving block 603 and the moving rod 604 are moved along the The threaded rod 602 moves and scrapes the outer side of the single lens 3 through the scraper 605 to ensure the cleanliness of the single lens 3 and the quality of the camera. When the moving rod 604 moves in the limit frame 606, it will drive the toggle block 810 to move to one side. When the toggle block 810 moves, the pull rod 805 moves synchronously with the toggle block 810, and at the same time, the roller 807 is driven to move through the clamping rod 806. Under the action of the V-shaped groove 803, the connecting plate 802 and the piston 801 are pulled toward the front end, so that the tension spring 808 is stretched until the triangular block 812 contacts one of the limit rods 813. Under the action of the limit rod 813, the triangular block 812 drives the toggle block 810 to the direction close to the pull rod 805. When the pull rod 805 is moved to one side, the air blocking plate 815 on the side is pushed to move, so that the through hole 816 is aligned with the connecting pipe 9. At this time, the connecting pipe 9 on the side is connected, and under the action of the connecting rod 817, the air blocking plate 815 on the other side moves toward the side, so that the through hole 816 is aligned with the connecting pipe 9. At this time, the connecting pipe 9 on the side is connected, and under the action of the connecting rod 817, the air blocking plate 815 on the other side moves toward the side, so that the through hole 816 is aligned with the connecting pipe 9. Hole 816 diverges from the connecting pipe 9. At this time, the connecting pipe 9 on the other side is blocked, so that the airflow generated by the blowing mechanism 8 is all blown out through the connecting pipe 9 on this side and the blowing pipe 10 on this side, ensuring that the wind force acts entirely on the scraper 605, thereby improving the cleaning effect. Similarly, when the pull rod 805 moves to the other side, the connecting pipe 9 on the other side is turned on, and the wind force acts entirely on the scraper 605. During continuous use, after the triangular block 812 and the limit rod 813 are worn, the moving distance of the pull rod 805 to both sides changes greatly. At this time, after the wind blocking plate 815 moves to the outermost side, the pull rod 805 will compress the spring gasket, so that the pull rod 805 can still move, and will not cause the device to get stuck, thereby improving the actual use effect.
[0048] In summary, by fixing the single lens 3 through the clamping mechanism 4, it is convenient to replace the worn or scratched single lens 3, facilitating the long-term use of the camera body 1;
[0049] Through the cleaning mechanism 6, the dust outside the single lens 3 is automatically scraped off, improving the imaging clarity of the camera body 1;
[0050] Through the housing 7, the air blowing mechanism 8, the connecting pipe 9 and the air blowing pipe 10, an air flow is generated and the air flow is controlled to blow towards the scraping strip 605 to clean the scraping strip 605, ensuring its subsequent scraping effect.
[0051] The above has described the preferred embodiments of the present patent in detail, but the present patent is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can also be made without departing from the gist of the present patent.
