[0002] With the improvement of construction technology and the popularization of elevators, the urbanization process has been promoted. As a large number of people move into cities, high-rise residential buildings continue to rise. The phenomenon of throwing objects from high places has also increased in various places. Throwing objects from high places seriously threatens public safety. In order to prevent the occurrence of injuries caused by throwing objects from high places, it is necessary not only to strengthen publicity and education, but also to increase safety facilities.

[0003] An existing intelligent building monitoring and alarm integrated device for preventing objects from being thrown from high places (Announcement No.: CN113311646B) is equipped with a convex mirror. The convex mirror can be adjusted by adjusting the angle of the component. The camera covers the convex mirror, which can cover a wider field of view, thereby saving cameras and reducing economic costs.

[0004] However, when this solution is actually used, the building image in the convex mirror is located in the center of the output image when the camera is shooting, and the four corners of the output image are not well utilized, which wastes resources. In addition, the cleaning brush blocks the camera when it moves relative to the convex mirror, resulting in blind spots in monitoring. Summary of the Invention

[0038] The following describes in detail a smart building alarm device for monitoring high-altitude objects provided by this application, in conjunction with the accompanying drawings and specific embodiments. It is also noted that, in order to make the embodiments more detailed, the following embodiments are optimal and preferred embodiments, and those skilled in the art may also adopt other alternative methods for implementation of some known technologies; and the accompanying drawings are only for more specific descriptions of the embodiments, and are not intended to specifically limit this application.

[0039] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The embodiment of the present application provides a smart building alarm device for monitoring high-altitude dropping of objects, including: a camera 1 and a speaker 2. A connecting rod 3 is installed at the front end of the side wall of the camera 1. One end of the connecting rod 3 is rotatably connected to a bracket 301. The interior of the bracket 301 is rotatably connected to a mirror 1 4. The bottom of the bracket 301 is rotatably connected to an adjustment rod 302. The other end of the adjustment rod 302 is rotatably connected to a connecting base 303. The top of the connecting base 303 is fixedly mounted with a mirror 2 5.

[0040] The front end of the camera 1 is sleeved with a dust cover 6, a lens 601 is clamped in the front opening of the dust cover 6, and a slide rail 602 is provided at the bottom of the dust cover 6. The slide rail 602 includes a slider 603 inside that can slide along the length direction. The bottom of the slider 603 is connected to a keel wiper 604;

[0041] During the installation phase, point the camera 1 directly at the facade of the building to be monitored. Adjust the elevation angle of the camera 1 according to the building height and monitoring needs so that the monitored building is within the imaging range of the camera 1. For example, the monitored building is located in the center of the imaging range of the camera 1.

[0042] At this time, by rotating the bracket 301, the angle of the bracket 301 relative to the camera 1 is adjusted so that the mirror 14 faces the position of the monitored building that needs to be further monitored, such as: perpendicular to the ground at the bottom of the monitored building; or tilting the mirror 14 toward the ground at the bottom of the monitored building; or tilting the mirror 14 toward the top or middle of the monitored building;

[0043] Then, by rotating the angle of mirror 1 4 relative to the bracket 301, the angle of mirror 1 4 relative to the monitored building is adjusted. Then, by rotating the adjustment rod 302, the adjustment rod 302 is swung relative to the bracket 301 to adjust the position of mirror 2 5 relative to mirror 1 4. By rotating mirror 2 5, mirror 2 5 is rotated relative to the connecting seat 303, so that mirror 2 5 can reflect the image of the monitored building in mirror 1 4 into the shooting range of camera 1, thereby achieving enhanced monitoring of the building.

[0044] Among them, there is a difference in shooting angle between the second mirror 5 and the camera 1, which is conducive to obtaining more detailed images of the monitored building and high-altitude objects, thereby helping to judge the behavior of high-altitude objects, which is safer and has higher resource utilization;

[0045] Among them, the camera 1 is facing the monitored building, and the monitored building is located in the center of the imaging range of the camera 1. The position of the second mirror 5 is adjusted to the corner position of the imaging range of the camera 1 through the cooperation of the connecting rod 3, the adjusting rod 302 and the connecting seat 303, thereby avoiding interference and making the output image more detailed and the monitoring effect better;

[0046] By providing a dust cover 6, the lens part of the camera 1, the face mirror 1 4 and the face mirror 2 5 are isolated from rain and dust outside, thereby keeping the lens part of the camera 1, the face mirror 1 4 and the face mirror 2 5 clean. At the same time, the dust cover 6 also has the function of blocking sunlight, which can reduce external light interference and ensure the quality of the output image;

[0047] The loudspeaker 2 plays an alarm role and alerts people around through sound;

[0048] The lens 601 ensures that light can be transmitted normally to the camera 1, mirror 1 4 and mirror 2 5. The lens 601 can be cleaned by cooperating with the slide rail 602, the slider 603 and the keel wiper 604. In addition, since the mirror 1 4 and the mirror 2 5 are provided to assist the camera 1 in imaging, it can be ensured that when the keel wiper 604 stays directly in front of the camera 1, that is, within the imaging range of the camera 1, the camera 1 is assisted by the imaging effect of the mirror 1 4 and the mirror 2 5, and can complete uninterrupted and complete monitoring work, thereby having a better monitoring effect on the building being measured.

[0049] Among them, the camera 1 is provided with a connecting rod 3, a mirror 1 4 and a mirror 2 5 on both sides. The positions of the two side mirrors 1 4 and 2 5 corresponding to the monitored building can be different to meet the monitoring requirements.

[0050] In actual use, a mirror 1 4 and a mirror 2 5 can be added to the upper and lower sides of the camera 1 respectively according to the on-site environment and usage requirements.

[0051] In this embodiment, Figure 3-Figure 8 As shown, one end of the connecting rod 3 is connected to a positioning block 304 through a thread, and one end of the positioning block 304 is attached to the outer wall of the bracket 301;

[0052] The connecting rod 3 and the bracket 301 are locked by the positioning block 304. The pre-tightening force between the positioning block 304 and the thread of the outer wall of the connecting rod 3 is used to achieve a tight fit between the positioning block 304 and the bracket 301, thereby achieving a firm locking effect.

[0053] The connection position between the connecting rod 3 and the bracket 301 is on the center line of the side wall of the bracket 301;

[0054] It is convenient to adjust the angle of the bracket 301 relative to the connecting rod 3, which is beneficial to maintaining the balance of the bracket 301 and facilitating stable and firm locking of the bracket 301 through the positioning block 304 .

[0055] A rotating shaft 3021 is passed through both ends of the adjusting rod 302, and a locking member 3022 is connected to the bottom of the rotating shaft 3021 through a thread;

[0056] By setting the rotating shaft 3021, the adjusting rod 302 can only swing smoothly relative to the bracket 301, and the connecting seat 303 can only rotate smoothly relative to the adjusting rod 302, thereby suppressing unnecessary shaking. Through the pre-tightening force generated by the thread between the locking member 3022 and the rotating shaft 3021, the locking member 3022 is tightly attached to the adjusting rod 302 to limit the relative movement between the rotating shaft 3021 and the adjusting rod 302, thereby achieving a locking effect.

[0057] The side wall of the dust cover 6 is provided with an opening, and baffles 605 are provided on both sides of the opening of the dust cover 6;

[0058] An installation opening is reserved on the side of the dust cover 6 to facilitate installation, inspection and maintenance. A good sealing effect is achieved through the detachable baffle 605 to reduce interference from impurities such as rainwater and dust.

[0059] The end of the slide rail 602 is connected to a motor 606, and a screw rod 607 is provided inside the slide rail 602. The screw rod 607 establishes a transmission relationship with the motor 606, and the slider 603 is connected to the screw rod 607 through a thread;

[0060] The motor 606 drives the screw rod 607 to rotate, and the screw rod 607 and the slider 603 generate relative motion, thereby driving the keel wiper 604 to move back and forth relative to the lens 601, so that the keel wiper 604 has a good cleaning effect on the lens 601.

[0061] The distance between the edge of the lens 601 and the mirror 1 4 is the same as the width of the mirror 1 4;

[0062] By setting the lens 601 of appropriate size, the mirror 4 has a good reflection angle to meet the need of reflecting the entire image of the monitored building, while ensuring space for the mirror 4 to rotate relative to the bracket 301.

[0063] The length of the keel wiper 604 is the same as the height of the dust cover 6;

[0064] By setting a keel wiper 604 with a length not less than the width of the lens 601, the cleaning path of the keel wiper 604 when moving relative to the lens 601 covers the lens 601, thereby achieving comprehensive cleaning of the lens 601 and ensuring imaging effect.

[0065] The middle part of the side wall of the camera 1 is connected to a controller 101;

[0066] The controller 101 realizes intelligent control of the entire device and can be connected to an external power supply to realize electrical control of the entire device.

[0067] The rear end of the camera 1 is connected to a mounting base 102 via bolts;

[0068] The mounting base 102 facilitates the installation of the camera 1 , and the angle between the mounting base 102 and the camera 1 can be determined during the installation process, thereby reducing the difficulty of the installation work.
