Abstract
Description
Technical Field
[0001] This invention relates to the field of camera technology, and more specifically to a surveillance camera. Background Technology
[0002] Surveillance cameras are quasi-cameras used in security applications. Their pixel count and resolution are higher than those of computer webcams. Most surveillance cameras are simply video capture devices and rarely have data storage capabilities. Surveillance cameras are mainly categorized by shape as bullet cameras, dome cameras, and high-speed dome cameras, and are widely used in various security fields such as schools, companies, banks, transportation, and smart city initiatives. In practical use, ordinary cameras are either exposed to the outside environment or have simple protective covers. However, when impacted or dropped, the camera and its protective cover cannot withstand the impact and are damaged. Furthermore, they cannot protect themselves in the event of a fire. Therefore, this application proposes a surveillance camera that can provide timely self-protection during use. Summary of the Invention
[0003] To overcome the shortcomings of existing technologies, this invention provides a surveillance camera that can protect itself in a timely manner during use.
[0004] The technical solution adopted by this invention to solve its technical problem is:
[0005] A surveillance camera includes an arc arm with a base sleeve formed at its lower end, a rotary motor fixed to the lower end of the base sleeve, and multiple protective leaves rotatably connected together at their lower ends. Each protective leaf has a protruding ridge extending outward from its right end and a protruding ridge extending inward from its left end. The protruding ridge extending inward from the left end of the outer protective leaf and the protruding ridge extending outward from the right end of the inner protective leaf can be hooked together. The innermost protective leaf has a backing plate formed outward from its left end and its lower end is fixed to the output shaft of the rotary motor. The arc arm is detachably connected to a middle plate, and a camera is installed at the lower end of the middle plate.
[0006] The lower end of the intermediate plate is formed with threads, and a spherical protective cover made of transparent tempered glass can be connected to the threads at the lower end of the intermediate plate.
[0007] The lower end of the base sleeve is formed with a spherical groove, and a movable cone that can rotate in the spherical groove is connected inside the spherical groove. The lower end of the movable cone is connected to a lower button by a spring, and a power line is fixed between the lower button and the rotary motor. Attached Figure Description

Detailed Implementation
[0018] Through observation Figures 2 to 6 An exemplary working process for improving protection capabilities, as shown in the figure, is as follows:
[0019] A surveillance camera includes an arc arm 01 with a base sleeve 02 formed at its lower end, and a rotary motor 06 fixed to the lower end of the base sleeve 02. It also includes multiple protective leaves 07 rotatably connected at their lower ends. Each protective leaf 07 has a protruding ridge extending outward from its right end and a protruding ridge extending inward from its left end. The protruding ridge extending inward from the left end of the outer protective leaf 07 can hook with the protruding ridge extending outward from the right end of the inner protective leaf 07. The innermost protective leaf 07 has a backing plate 08 formed outward from its left end, and its lower end is fixed to the output shaft of the rotary motor 06. The 01 is detachably connected to the middle plate 10, and the camera 11 is installed at the lower end of the middle plate 10. In actual use, the camera 11 of ordinary cameras is either exposed to the outside or equipped with a simple protective cover. However, when it is impacted or the camera is dropped, the camera 11 and the protective cover cannot withstand the impact and are damaged. In this application, by controlling the opening and closing of the rotary motor 06, the rotary motor 06 can drive the innermost protective leaf 07 to rotate clockwise in the horizontal direction, so that the protrusion extending outward from the right end of the innermost protective leaf 07 hooks the second protective leaf. The protruding ridge extending inward from the left end of the protective leaf 07 causes the innermost protective leaf 07 to drive the second protective leaf 07 to rotate. Through the mutual interaction of multiple protective leaves 07, they form a complete spherical protective cover along the output shaft of the rotary motor 06, thus protecting the camera 11 from below. Conversely, by rotating the innermost protective leaf 07 counterclockwise through the output shaft of the rotary motor 06, the outward-forming backing plate 08 at the left end of the innermost protective leaf 07 sequentially contacts the left ends of the remaining protective leaves 07. By pushing the remaining multiple protective leaves 07 together to retract, the multiple protective leaves 07 can be gradually stacked and ultimately kept within the width of one protective leaf 07, realizing the process of automatic opening for protection and automatic retraction; similarly, in the event of a fire in a building with a large amount of smoke, the above-mentioned protection process can prevent the high-temperature smoke from damaging the camera and contaminating and soiling the protective cover 12, and also prevent the flame from directly acting on the protective cover 12, causing the protective cover 12 to crack and be damaged, thereby preventing the camera from being damaged in a fire.
[0020] Through observation Figures 1 to 9 An exemplary working process for increasing protective capabilities, as shown in the figure, is as follows:
[0021] The lower end of the intermediate plate 10 is threaded, and the protective cover 12, which is made of transparent tempered glass and has a spherical structure, can be connected to the thread at the lower end of the intermediate plate 10. By tightening the protective cover 12 onto the thread at the lower end of the intermediate plate 10, the protective cover 12 can protect the camera 11, further improving the protection capability of the camera 11, thereby blocking the impact and collision of the camera 11 from the outside.
[0022] Through observation Figures 1 to 9 An exemplary working process for automatic cleaning, as shown in the diagram, is as follows:
[0023] A cleaning strip 09 is fixedly connected to the inner wall of the innermost protective leaf 07. The cleaning strip 09 can contact the outer surface of the protective cover 12. When the innermost protective leaf 07 is rotated by the rotating motor 06, the cleaning strip 09 can contact the outer surface of the protective cover 12 and rub against it. The cleaning strip 09 cleans the outer surface of the protective cover 12. It can clean the dust and dirt on the outer surface of the protective cover 12 in time during use, thereby preventing dust and dirt from affecting the image captured by the camera 11.
[0024] Through observation Figures 1 to 9 An exemplary working process to prevent damage from drops can be obtained from the diagram as follows:
[0025] The lower end of the base sleeve 02 is formed with a spherical groove 03. A movable cone 04, capable of rotating within the spherical groove 03, is connected inside the groove. A lower button 05 is connected to the lower end of the movable cone 04 via a spring. A power cord is fixed between the lower button 05 and the rotary motor 06. When the camera falls, the button 05 on the lowest movable cone 04 will be the first to contact the ground or an obstacle. The impact will press the button 05, transmitting current through the power cord to the rotary motor 06, causing the protective leaf 07 to rotate clockwise. This will cause multiple protective leaves to rotate. 07 quickly protects the protective cover 12 and the camera 11, preventing them from colliding with the ground or obstacles and causing damage, thus completing the protection process quickly; at the same time, the movable cone 04 can rotate within the spherical groove 03 due to its own center of gravity, ensuring that the movable cone 04 remains perpendicular to the horizontal plane. Even if the bolts for mounting the camera come loose and cause the camera to tilt, the movable cone 04 can be aligned with the ground, thus ensuring that the button 05 is always downward and can be pressed in time when the camera falls, thereby ensuring that multiple protective leaves 07 can be deployed in time.
[0026] Through observation Figures 1 to 9 An exemplary working process for multi-functional protection, as shown in the figure, is as follows:
[0027] A plate 15 is fixedly connected to the upper end of the intermediate plate 10. A temperature sensor 16, a distance sensor 17, and a smoke sensor 18 are installed on the side wall of the plate 15. The temperature sensor 16, the distance sensor 17, and the smoke sensor 18 are all connected to the rotary motor 06 through an electronic control switch. Through the temperature sensor 16, the distance sensor 17, and the smoke sensor 18, the environmental changes around the camera can be detected in a timely manner. When a rapid increase in temperature, a rapid decrease in distance from external objects, or the presence of smoke are detected, the rotary motor 06 can be turned on through the electronic control switch, thereby enabling the deployment of multiple protective leaves 07 to complete the protection. Conversely, after the influencing factors are eliminated, the rotary motor 06 can drive the multiple protective leaves 07 to reset and retract.
[0028] Through observation Figures 1 to 9 An exemplary working process for improving security, as shown in the figure, is as follows:
[0029] The upper end of the intermediate plate 10 is formed with a circular wall 13. Two filter screens 14 that can be spliced into a ring can be detachably connected to the circular wall 13 by bolts. After the two detachable filter screens 14 are spliced into a ring and installed on the circular wall 13, the temperature sensor 16, the distance sensor 17 and the smoke sensor 18 can be protected by the two filter screens 14, so as to avoid damage to the temperature sensor 16, the distance sensor 17 and the smoke sensor 18 in the event of a fire.
[0030] Through observation Figures 1 to 9 An exemplary self-protection process can be derived from the diagram as follows:
[0031] The surveillance camera also includes a hidden box 19 and a lead screw 20 rotatably connected in the hidden box 19. One end of the plate 15 is connected to the lead screw 20 through a threaded hole, and the other end is slidably connected in the hidden box 19. The lead screw 20 is driven by a geared motor installed in the hidden box 19. The temperature sensor 16, the distance sensor 17, and the smoke sensor 18 are all connected to the geared motor through another electronic control switch. When a fire occurs and the camera needs to be protected, the temperature sensor 16 or the smoke sensor 18 can detect information and control the geared motor to start, causing the geared motor to drive the lead screw 20 to rotate. This causes the lead screw 20 to lift the plate 15, allowing the plate 15 and the rest of the plate to retract back into the hidden box 19, thus performing an automatic protection process in a timely manner. Similarly, protective doors 23 are slidably connected to both ends of the open lower part of the hidden box 19. The two protective doors 23 are driven by two electric telescopic rods 22 fixed in the hidden box 19. A linkage button 21 for controlling the opening and closing of the two electric telescopic rods 22 is installed on the top inner side of the hidden box 19. When the tablet 15 retracts, the tablet 15 can press the linkage button 21, which will control the two electric telescopic rods 22 to slide the two protective doors 23 closer together to complete the docking. This allows the two protective doors 23 to cover the lower part of the hidden box 19, thus protecting the tablet 15 and the rest of the device. This prevents external smoke or flames from damaging the camera and also allows the camera to be better preserved in the event of a fire, reducing property loss.
[0032] Through observation Figures 1 to 9 An exemplary working process for improving fire resistance, as shown in the figure, is as follows:
[0033] The inner walls of the hidden box 19 and the two protective doors 23 are all provided with heat-insulating protective plates made of heat-insulating material; the hidden box 19 and the two protective doors 23 are all made of fireproof material; they can protect the parts inside in the event of a fire, and prevent the hidden box 19 or the protective doors 23 from being damaged by high temperature and thus unable to protect the parts inside the hidden box 19.
