Detailed Implementation

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Example 1:

[0029] Please see Figure 1-3 As shown, the present invention is a monitoring and alarm device, comprising a conventional monitoring body 1 and an audible and visual alarm 2 disposed above the monitoring body 1; one end of the monitoring body 1 has a conventional camera 101, a conventional infrared sensor 102, a conventional microwave sensor 103, and a pair of conventional lighting lamps 104; the two lighting lamps 104 are respectively disposed on opposite sides of the infrared sensor 102; the infrared sensor 102 is disposed between the camera 101 and the microwave sensor 103; when the infrared sensor 102 and the microwave sensor 103 sound simultaneously... When the camera 101 is activated, the audible and visual alarm 2 is a conventional component in this field. A first rotary drive assembly 3 is provided above the monitoring body 1. A second rotary drive assembly 4 is connected to the first rotary drive assembly 3. Both the monitoring body 1 and the audible and visual alarm 2 are mounted on the second rotary drive assembly 4. The first rotary drive assembly 3 can drive the monitoring body 1 to rotate horizontally. The second rotary drive assembly 4 can drive the monitoring body 1 to rotate vertically. A lifting assembly 5 is installed on the second rotary drive assembly 4. A cleaning assembly 6 for dust removal from one end of the monitoring body 1 is connected to the lifting assembly 5. In use, infrared sensor 102 detects infrared signals and microwave sensor 103 detects microwave signals to determine if there is movement in the detection area. When both infrared sensor 102 and microwave sensor 103 respond simultaneously, camera 101 records the detection area and triggers an alarm via audible and visual alarm 2. Simultaneously, the first rotary drive assembly 3 drives the monitoring body 1 to rotate horizontally, and the second rotary drive assembly 4 drives it to rotate vertically, enabling dynamic tracking of objects. The use of infrared sensor 102 and microwave sensor 103 effectively reduces false alarms and improves the monitoring and alarm effect. Furthermore, periodically moving the monitoring body 1 to a position corresponding to the cleaning assembly 6 via the first and second rotary drive assemblies 3 and 4, and then using the lifting assembly 5 to move the cleaning assembly 6 vertically, causes it to clean one end of the monitoring body 1, effectively reducing dust on the camera 101, infrared sensor 102, microwave sensor 103, and lighting lamp 104, ensuring the effectiveness of the monitoring body 1 and extending its lifespan.

[0030] Example 2:

[0031] Based on Example 1, as follows Figure 3-5As shown, the first rotary drive assembly 3 includes a support base 301 with a "┐"-shaped structure; the vertical section of the support base 301 is bolted to the main building structure; the horizontal section of the support base 301 is vertically bolted to a first motor 302; the output end of the first motor 302 passes through the horizontal section of the support base 301 and is keyed to a first gear 303; a second gear 304 meshes with the first gear 303; the second gear 304 is keyed to the outer periphery of a first rotating shaft 305; the upper end of the first rotating shaft 305 is rotatably connected to the horizontal section of the support base 301; the lower end of the first rotating shaft 305 is connected to the second rotary drive assembly 4; the second rotary drive assembly 4 includes a mounting plate 401 horizontally bolted to the lower end of the first rotating shaft 305; bearing arms 402 are vertically welded downwards to opposite sides of the mounting plate 401; a second motor 403 is disposed between the two bearing arms 402; the second...

In use, the first motor 302 drives the second rotary drive assembly 4 to rotate horizontally via the first gear 303, the second gear 304, and the first rotating shaft 305, thereby achieving the horizontal rotation of the monitoring body 1. Then, the second motor 403 drives the worm gear 404 to rotate, which in turn drives the monitoring body 1 to rotate vertically via the worm wheel 406, the second rotating shaft 405, the first pulley 407, the second pulley 408, and the third rotating shaft 409. This effectively increases the monitoring area of ​​the monitoring body 1, thereby ensuring the monitoring effect of the monitoring body 1.

[0032] Example 3:

[0033] Based on Example 2, as follows Figure 2 and Figure 6-8As shown, the lifting assembly 5 includes a third motor 501 vertically bolted to the upper surface of the mounting plate 401; the output shaft of the third motor 501 passes through the mounting plate 401 and is keyed to a third gear 502; a fourth gear 503 meshes with the third gear 502; the fourth gear 503 is keyed to the outer periphery of a threaded sleeve 504; the threaded sleeve 504 is vertically inserted into the mounting plate 401 and is rotatably connected to the mounting plate 401; a screw 505 is internally threaded into the threaded sleeve 504; directional rods 506 are vertically arranged on both sides of the screw 505; both directional rods 506 are slidably inserted into the mounting plate 401; the lower end of the screw 505 and the two directional rods 506 are also connected to the mounting plate 401. The lower ends of 6 are all connected to the cleaning assembly 6; the cleaning assembly 6 includes a dust collection box 601 bolted to the lower end of the screw 505; the lower ends of the two directional rods 506 are all bolted to the top wall of the dust collection box 601; an air outlet 602 is provided on the side wall of the dust collection box 601 away from the monitoring body 1; a conventional negative pressure fan 603 of the art is bolted inside the air outlet 602; multiple sets of suction holes 604 are arranged side by side from top to bottom on the side wall of the dust collection box 601 near the monitoring body 1; a set of bristles 605 made of silicone is provided between two adjacent sets of suction holes 604; one end of each set of bristles 605 is vertically welded to the side wall of the dust collection box 601 near the monitoring body 1. In use, the monitoring body 1 is adjusted to a horizontal position by the second rotary drive assembly 4, and one end of the monitoring body 1 is oriented towards the cleaning assembly 6 by the first rotary drive assembly 3. Then, the third motor 501 drives the screw sleeve 504 to rotate via the third gear 502 and the fourth gear 503, causing the screw sleeve 504 to move downward via the screw 505 and the directional rod 506. As the dust cleaning box 601 moves from top to bottom past one end of the monitoring body 1, the other end of the multiple sets of bristles 605 cleans one end face of the monitoring body 1. At the same time, the negative pressure fan 603 creates a negative pressure state inside the dust cleaning box 601, causing the dust swept off one end face of the monitoring body 1 to be sucked into the dust cleaning box 601 through the suction hole 604. This effectively ensures the cleaning efficiency and effect of the monitoring body 1, and also ensures the use effect of the monitoring body 1.

The filter block 608 filters the air in the dust collection box 601, effectively ensuring the dust removal effect. In addition, by designing the upper ends of the two positioning posts 611 to slide into the two through holes 609 and be adsorbed onto the lower surface of the two magnetic posts 610 respectively, the filter block 608 can be easily installed and replaced, effectively ensuring the use effect of the cleaning component 6.
