[0038] The following is a detailed description of a smart building alarm device for monitoring high-altitude objects provided by the present application in combination with the accompanying drawings and specific embodiments. At the same time, it is explained here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art may also adopt other alternative methods for some known technologies; and the accompanying drawings are only for a more specific description of the embodiments, and are not intended to specifically limit the present application.

[0039] like Figure 1 , Figure 2 , Figure 3 and Figure 4 An alarm device for monitoring high-altitude dropping of objects in a smart building is shown in the embodiment of the present application, comprising: 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 inside of the bracket 301 is rotatably connected to a mirror 1 4, the bottom of the bracket 301 is rotatably connected to an adjusting rod 302, the other end of the adjusting rod 302 is rotatably connected to a connecting seat 303, and a mirror 2 5 is fixedly installed on the top of the connecting seat 303;

[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, a slide rail 602 is arranged at the bottom of the dust cover 6, the slide rail 602 includes a slider 603 inside which can slide along the length direction, and a keel wiper 604 is connected to the bottom of the slider 603;

[0041] During the installation phase, the camera 1 is pointed directly at the facade of the building to be monitored. According to the height of the building and the monitoring needs, the elevation angle of the camera 1 is adjusted 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, adjusting the angle of the bracket 301 relative to the camera 1, the mirror 4 is facing the position of the monitored building that needs to be further monitored, such as: the mirror 4 is perpendicular to the ground at the bottom of the monitored building; or the mirror 4 is tilted toward the ground at the bottom of the monitored building; or the mirror 4 is tilted toward the top or middle of the monitored building;

[0043] Then, by rotating the angle of the mirror 1 4 relative to the bracket 301, the angle of the mirror 1 4 relative to the monitored building is adjusted, and then by rotating the adjustment rod 302, the adjustment rod 302 is swung relative to the bracket 301, and the position of the mirror 2 5 relative to the mirror 1 4 is adjusted. By rotating the mirror 2 5, the mirror 2 5 is rotated relative to the connecting seat 303, so that the mirror 2 5 can reflect the image of the monitored building in the mirror 1 4 into the shooting range of the camera 1, so as to achieve 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 high-altitude object throwing behavior, which is safer and has higher resource utilization;

[0045] 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 mirror 2 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, so as to avoid interference, and at the same time make 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 mirror 1 4 and the mirror 2 5 are isolated from rain and dust outside, so as to keep the lens part of the camera 1, the mirror 1 4 and the 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 is used to give an alarm, and the surrounding people are reminded by sound;

[0048] The lens 601 is used to ensure that light can be normally transmitted 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 measured building.

[0049] Among them, the two sides of the camera 1 are provided with a connecting rod 3, a mirror 1 4 and a mirror 2 5 and other structures, and the positions of the two side mirrors 1 4 and the two side mirrors 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 positioning block 304 and the bracket 301 are tightly fitted by the pre-tightening force between the positioning block 304 and the outer wall thread of the connecting rod 3, so as to achieve a firm locking effect.

[0053] The connection position between the connecting rod 3 and the bracket 301 is located 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 is beneficial to stably and firmly locking the bracket 301 through the positioning block 304 .

[0055] The two ends of the adjusting rod 302 are penetrated by a rotating shaft 3021, and the bottom of the rotating shaft 3021 is connected with a locking member 3022 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 rain 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 and the motor 606 establish a transmission relationship, 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 suitable size, the mirror 4 has a good reflection angle to meet the need of reflecting the whole picture of the monitored building, while ensuring the 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 the 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 the imaging effect.

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

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

[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.
