Description

Technical Field

[0001] This invention relates to the field of security, and in particular to a security monitoring and alarm device. Background Technology

[0002] To strengthen technical security and safety measures in public places such as residential communities, office buildings, and hotels, it is necessary to use monitoring and alarm equipment for real-time monitoring. Among these, the most widely used method is to use smoke sensors to monitor and alarm on fire situations in real time.

[0003] However, most existing monitoring and alarm equipment is installed in fixed locations, which may create blind spots. When monitoring a fire, the smoke generated by the fire may prevent the monitoring and alarm equipment from detecting the smoke. If the smoke cannot be detected, people will not be able to report the fire in time to resolve the potential fire hazard. Furthermore, because the monitoring and alarm equipment is exposed to the outside world for a long time, dust may accumulate on its surface. When too much dust accumulates, it may cause the alarm to fail to be triggered in time or to make false alarms, affecting the accuracy of the monitoring and alarm equipment.

[0004] Therefore, we propose a security monitoring and alarm device to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a security monitoring and alarm device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

A drive shaft is movably connected to the bottom of the base via bearings. The output end of the motor is welded to the bottom of the drive shaft.

A cylinder is provided at the top of the inner cavity of the monitoring box. A pressure plate is fixedly connected to the bottom of the cylinder. A control button is provided at the bottom of the inner cavity of the monitoring box and is electrically connected to the buzzer. A smoke sensor is provided on the left side of the monitoring box. The cleaning mechanism includes a vertical plate and a rotating rod.

[0008] The transmission mechanism includes a threaded rod and a sliding ring. The threaded rod is fixedly connected to the top of the drive shaft. A threaded sleeve is threadedly connected to the outer surface of the threaded rod. A connecting rod is welded to the left side of the threaded sleeve. A sliding sleeve is welded to the left side of the connecting rod. The monitoring box is welded to the left side of the sliding sleeve.

[0009] In a further embodiment, a connecting plate is welded to the right side of the upright plate, and the connecting plate is welded to the left side of the base. A rotating shaft is movably connected to the inner surface of the upright plate. A cleaning brush is fixedly connected to the right side of the rotating shaft. A driven gear is welded to the left side of the rotating shaft. A protruding plate is welded to the bottom of the left side of the upright plate. The rotating rod is movably connected to the inner surface of the protruding plate. A driving gear is welded to the top of the rotating rod, and the right side of the driving gear meshes with the bottom of the driven gear.

[0010] In a further embodiment, a driven pulley is welded to the bottom of the rotating rod, and a driving pulley is welded to the outer surface of the driving shaft. The driving pulley and the driven pulley are connected by a transmission belt.

[0011] In a further embodiment, the sliding ring is welded to the top of the base, and the sliding sleeve is slidably connected to the outer surface of the sliding ring.

[0012] In a further embodiment, a blocking block is welded to the top of the sliding ring, and the diameter of the blocking block is larger than the diameter of the sliding sleeve.

[0013] In a further embodiment, a protective frame is welded to the top of the monitoring box, and the protective frame is located on the surface of the buzzer.

[0014] In a further embodiment, a limiting block is welded to the top of the threaded rod, and the diameter of the limiting block is larger than the diameter of the threaded sleeve.

[0015] In a further embodiment, the output terminal of the smoke sensor is electrically connected to a data analysis module, the output terminal of the data analysis module is electrically connected to a data transmission module, the output terminal of the data transmission module is electrically connected to a central processing unit, the output terminal of the central processing unit is electrically connected to a control module, and the output terminal of the control module is electrically connected to the input terminal of the cylinder.

[0016] In a further embodiment, a bracket is welded to the bottom of the base, and the top of the bracket contacts the bottom of the motor.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] Firstly, in this invention, the output end of the motor drives the drive shaft to rotate, and the drive shaft drives the threaded rod welded at the top to make a circular motion. The threaded rod drives the threaded sleeve to rotate through the thread. The threaded sleeve drives the sliding sleeve to move around the sliding ring 360 degrees through the connecting rod. At the same time, it can also change the up and down position, thereby improving the monitoring range of the smoke sensor and reducing the occurrence of blind spots that cannot be accurately monitored.

[0019] Secondly, in this invention, when the motor starts, it synchronously drives the rotating rod to rotate, which in turn drives the driving gear to rotate. The driving gear drives the driven gear to rotate through tooth meshing, which in turn drives the rotating shaft to rotate. The rotating shaft drives the cleaning brush to rotate. When the smoke sensor moves to the position of the cleaning brush, the rotation of the cleaning brush can clean the smoke sensor, preventing the surface of the smoke sensor from accumulating too much dust and affecting the accuracy of monitoring.

[0020] Thirdly, in this invention, a smoke sensor monitors the smoke in the outside world. When the smoke sensor detects smoke, it transmits the signal to the data analysis module for analysis. The data analysis module then transmits the analyzed data to the central processing unit via the data transmission module. The central processing unit activates the cylinder through the control module. The cylinder extends and moves the pressure plate downward to press the control button. Since the control button is electrically connected to the buzzer, the buzzer sounds an alarm to alert people, thus achieving the function of automatic monitoring and alarm.

[0030] Please see Figures 1-7 A security monitoring and alarm device includes: a base 1, a motor 10, a monitoring box 5, and a cleaning mechanism 7. The bottom of the base 1 is welded with multiple support legs 12. The bottom of the base 1 is movably connected to a drive shaft 14 via bearings.

[0031] The transmission mechanism 2 includes a threaded rod 201 and a sliding ring 202. The threaded rod 201 is fixedly connected to the top of the drive shaft 14. A threaded sleeve 207 is threadedly connected to the outer surface of the threaded rod 201. A connecting rod 203 is welded to the left side of the threaded sleeve 207.

[0032] In this invention, the output end of the motor 10 drives the drive shaft 14 to rotate. The drive shaft 14 drives the threaded rod 201 welded to the top to make a circular motion. The threaded rod 201 drives the threaded sleeve 207 to rotate through the thread. The threaded sleeve 207 drives the sliding sleeve 204 to move around the sliding ring 202 360 degrees through the connecting rod 203. At the same time, it can also change the up and down position, thereby improving the monitoring range of the smoke sensor 6 and reducing the occurrence of blind spots that cannot be accurately monitored.

[0033] Specifically, a connecting plate 8 is welded to the right side of the upright plate 701, and the connecting plate 8 is welded to the left side of the base 1.

A driven gear 703 is welded to the left side of the rotating shaft 702. A protruding plate 706 is welded to the bottom left side of the upright plate 701. A rotating rod 705 is movably connected to the inner surface of the protruding plate 706. A driving gear 704 is welded to the top of the rotating rod 705, and the right side of the driving gear 704 meshes with the bottom of the driven gear 703.

[0034] In this invention, when the motor 10 starts, it synchronously drives the rotating rod 705 to rotate. The rotating rod 705 drives the driving gear 704 to rotate. The driving gear 704 drives the driven gear 703 to rotate through tooth meshing. The driven gear 703 drives the rotating shaft 702 to rotate. The rotating shaft 702 drives the cleaning brush 707 to rotate. When the smoke sensor 6 moves to the position of the cleaning brush 707, the smoke sensor 6 can be cleaned by the rotation of the cleaning brush 707, so as to avoid the surface of the smoke sensor 6 accumulating too much dust and affecting the accuracy of monitoring.

[0035] Specifically, a driven pulley 9 is welded to the bottom of the rotating rod 705, and a driving pulley 13 is welded to the outer surface of the driving shaft 14. The driving pulley 13 and the driven pulley 9 are connected by a transmission belt.

[0036] By setting the driven pulley 9, the driving pulley 13, and the driven pulley 9, the motor 10 can synchronously drive the transmission mechanism 2 and the cleaning mechanism 7 to work at the same time during the driving process, thus achieving a linkage effect.

[0037] Specifically, the sliding ring 202 is welded to the top of the base 1, and the sliding sleeve 204 is slidably connected to the outer surface of the sliding ring 202.

[0038] Specifically, a blocking block 206 is welded to the top of the sliding ring 202, and the diameter of the blocking block 206 is larger than the diameter of the sliding sleeve 204.

[0039] Specifically, a protective frame 3 is welded to the top of the monitoring box 5, and the protective frame 3 is located on the surface of the buzzer 4.

[0040] Specifically, a limiting block 205 is welded to the top of the threaded rod 201, and the diameter of the limiting block 205 is larger than the diameter of the threaded sleeve 207.

[0041] Specifically, the output of the smoke sensor 6 is electrically connected to the data analysis module 21, the output of the data analysis module 21 is electrically connected to the data transmission module 20, the output of the data transmission module 20 is electrically connected to the central processing unit 19, the output of the central processing unit 19 is electrically connected to the control module 18, and the output of the control module 18 is electrically connected to the input of the cylinder 16.

[0042] In this invention, a smoke sensor 6 monitors external smoke. When the smoke sensor 6 detects smoke, it transmits the signal to a data analysis module 21 for analysis. The data analysis module 21 then transmits the analyzed data to a central processing unit 19 via a data transmission module 20. The central processing unit 19 activates a cylinder 16 via a control module 18. The cylinder 16 extends and moves a pressure plate 15 downwards, pressing against a control button 17. Since the control button 17 is electrically connected to a buzzer 4, the buzzer 4 sounds an alarm to alert people, thus achieving the function of automatic monitoring and alarm.

[0043] Specifically, a bracket 11 is welded to the bottom of the base 1, and the top of the bracket 11 contacts the bottom of the motor 10.

[0044] The working principle of this invention is as follows: The output end of the motor 10 drives the drive shaft 14 to rotate. The drive shaft 14 drives the threaded rod 201 welded to the top to move in a circular motion. The threaded rod 201 drives the threaded sleeve 207 to rotate through the thread. The threaded sleeve 207 drives the sliding sleeve 204 to move 360 ​​degrees around the sliding ring 202 through the connecting rod 203. At the same time, it can also change the up and down position, thereby improving the detection range of the smoke sensor 6 and reducing the occurrence of blind spots that cannot be accurately detected. When the motor 10 drives, it synchronously drives the rotating rod 705 to rotate. The rotating rod 705 drives the drive gear 704 to rotate. The drive gear 704 drives the driven gear 703 to rotate through the meshing of the teeth. The driven gear 703 drives the rotating shaft 702 to rotate. The rotating shaft 702 drives the cleaning brush 707 to move inward. When the smoke sensor 6 moves to the position of the cleaning brush 707, the rotation of the cleaning brush 707 can clean the smoke sensor 6, preventing excessive dust from adhering to the surface of the smoke sensor 6 and affecting the accuracy of monitoring. The smoke sensor 6 monitors the smoke in the outside world. When the smoke sensor 6 detects smoke, it transmits the signal to the data analysis module 21 for analysis. The data analysis module 21 transmits the analyzed data to the central processing unit 19 through the data transmission module 20. The central processing unit 19 starts the cylinder 16 through the control module 18. The cylinder 16 extends and drives the pressure plate 15 to move downward and press against the control button 17. Since the control button 17 is electrically connected to the buzzer 4, the buzzer 4 will sound an alarm to alert people, thus playing the role of automatic monitoring and alarm.
