[0002] Low-voltage security refers to a series of technologies and equipment that utilize low-voltage, low-current low-voltage systems to achieve security and prevention functions. Low-voltage security infrared sensing monitoring and alarm devices are a type of equipment system that uses infrared sensing technology, monitoring technology, and alarm technology to achieve security and monitoring of specific areas.

[0003] For example, CN205486598U discloses an infrared detection alarm monitoring camera device, including a base, a housing, a PCB control board fixed on the base, a camera lens mounted on the base and connected to the PCB control board, and a protective glass layer fixed on the housing and corresponding to the camera lens; wherein, the PCB control board is provided with an infrared detection switch module, a wireless network module, a fingerprint recognition module and an alarm module connected to the control processing chip.

[0004] In the existing technology, infrared sensing devices work by detecting infrared rays emitted by objects. However, external dust can affect the operation of infrared rays, interfering with the reception and transmission of infrared signals, resulting in decreased sensing sensitivity and false alarms or missed alarms. At the same time, it can also block some of the monitoring light, making the captured images blurry and dark, reducing the clarity and contrast of the images, and affecting the normal operation of the device. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art that external dust interferes with the reception and transmission of infrared signals, leading to a decrease in sensing sensitivity and blocking some of the monitoring light, thus affecting the normal operation of the device. Therefore, a low-voltage security infrared sensing monitoring and alarm device is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a low-voltage security infrared sensing monitoring and alarm device, comprising a fixed housing, an adjustment mechanism installed inside the fixed housing, a transparent cover installed at the bottom of the fixed housing, and a cleaning mechanism installed outside the transparent cover.

A rotating rod is fixedly connected to the middle of the four connecting blocks, and a first motor is fixedly connected to one end of one of the rotating rods. One side of the first motor is fixedly connected to the outer surface of the fixed housing.

[0007] Preferably, both ends of the two rotating rods are fixedly connected to a first gear, and the two first gears mesh with each other.

[0008] Preferably, the adjustment mechanism includes a fixed plate, the end of which is fixedly connected to the inside of the transparent cover, a connecting rod is rotatably connected to one side of the fixed plate, a rotating disk is fixedly connected to one end of the connecting rod, and a meshing tooth pattern is provided on the outer side of the rotating disk, with multiple meshing tooth patterns discontinuously distributed on the outside of the rotating disk.

[0012] Preferably, a mounting bracket is fixedly connected to the top of the fixed housing, and the mounting bracket is located on the outside of the alarm.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, the first motor drives the rotating rod connected to it to rotate. Two meshing first gears are fixed on the outside of the rotating rod, which can drive another rotating rod to rotate, thereby driving the connecting block and the cleaning plate to move.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides a low-voltage security infrared sensing monitoring and alarm device, including a fixed housing 1. An adjustment mechanism 6 is installed inside the fixed housing 1. A transparent cover 2 is installed at the bottom of the fixed housing 1. A cleaning mechanism 3 is installed outside the transparent cover 2. The cleaning mechanism 3 includes cleaning plates 31. The inner sides of two cleaning plates 31 overlap the outer surface of the transparent cover 2. Connecting blocks 32 are fixedly connected to both ends of the two cleaning plates 31. Rotating rods 34 are fixedly connected to the middle of the four connecting blocks 32. A first motor 35 is fixedly connected to one end of one of the rotating rods 34. One side of the first motor 35 is fixedly connected to the outer surface of the fixed housing 1. First gears 33 are fixedly connected to both ends of the two rotating rods 34. The two first gears 33 mesh with each other.

[0024] By controlling the first motor 35 to work, the rotating rod 34 connected to it is driven to rotate. The first gear 33 is fixed to the outside of the rotating rod 34, and the two first gears 33 at the same end of the rotating rod 34 mesh with each other, which can drive the other rotating rod 34 to rotate, thereby driving the connecting block 32 and the cleaning plate 31 to move. The two cleaning plates 31 move to both sides outside the transparent cover 2, thereby cleaning the outer surface of the transparent cover 2, preventing dust from affecting the operation of infrared light, and preventing the monitoring light from being blocked, thus improving the infrared sensing and monitoring effect.

[0025] Example 2: Figure 1 and Figure 4 As shown, the adjustment mechanism 6 includes a fixed plate 61, the end of which is fixedly connected to the inside of the transparent cover 2. A connecting rod 62 is rotatably connected to one side of the fixed plate 61, and a rotating disk 69 is fixedly connected to one end of the connecting rod 62. The outer side of the rotating disk 69 is provided with meshing teeth 610, and multiple meshing teeth 610 are discontinuously distributed on the outside of the rotating disk 69. A second gear 64 meshes with one side of the meshing teeth 610. A second motor 63 is fixedly connected to one side of the fixed plate 61, and the output end of the second motor 63 passes through one side of the fixed plate 61 and is fixedly connected to the middle of the second gear 64. A fixed rod 67 is fixedly connected to the other side of the rotating disk 69. Connecting seats 66 are fixedly connected to both sides of the outer side of the fixed rod 67. An infrared sensor 65 is fixedly connected to one side of the connecting seat 66, and a monitor 68 is fixedly connected to the other side of the connecting seat 66. An alarm 5 is fixedly connected to the top of the fixed housing 1. A mounting bracket 4 is fixedly connected to the top of the fixed housing 1, and the mounting bracket 4 is located outside the alarm 5.

[0026] The overall effect of this embodiment is that the entire device is fixed at the installation location through the mounting holes on the mounting bracket 4. The infrared sensor 65 is used for infrared sensing, and the monitor 68 is used for real-time monitoring of the image. The second motor 63 drives the second gear 64 to rotate. The outer surface of the second gear 64 is provided with teeth corresponding to the meshing teeth 610. Multiple discontinuous meshing teeth 610 are opened on the outer surface of the rotating disk 69, and the multiple meshing teeth 610 are distributed in a ring at equal intervals. When the second gear 64 meshes with the meshing teeth 610, it drives the rotating disk 69 to rotate. Subsequently, the second gear 64 separates from the meshing teeth 610. After the second gear 64 rotates one revolution, it meshes with the next meshing teeth 610, thereby driving the rotating disk 69 to rotate at intervals, and driving the infrared sensor 65 and the monitor 68 to rotate at intervals, thereby monitoring different locations. After detecting an abnormal situation, the alarm 5 can be controlled to alarm.

[0027] The device is used and operates as follows: The second motor 63 drives the second gear 64 to rotate, which in turn drives the rotating disk 69 to rotate at intervals. This causes the infrared sensor 65 and the monitor 68 to rotate at intervals, thereby monitoring different locations. By controlling the first motor 35, the rotating rod 34 connected to it is driven to rotate. Two meshing first gears 33 are fixed to the outside of the rotating rod 34, which can drive another rotating rod 34 to rotate, thereby driving the connecting block 32 and the cleaning plate 31 to move. The two cleaning plates 31 move to both sides outside the transparent cover 2, thereby cleaning the outer surface of the transparent cover 2.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
