Description

Technical Field

[0001] This utility model belongs to the field of security technology for low-voltage engineering, and in particular relates to a security monitoring device for low-voltage engineering. Background Technology

[0002] Low-voltage electrical engineering security refers to a series of engineering and technical activities that use low-voltage systems for security protection, aiming to ensure the normal and safe operation of low-voltage systems. Among these, video surveillance is the main means of low-voltage electrical engineering security.

[0003] Chinese utility model patent CN221575496U discloses a security monitoring device for low-voltage engineering. This device, through its cleaning mechanism, first sprays cleaning agent from a tank onto the lens surface via a delivery pipe when dust needs to be cleaned from the monitor lens. Then, a third motor is activated, driving a screw to rotate. Since the slider is restricted by the brush and cannot rotate, the screw drives the slider to move along the screw's direction. The slider then drives the brush, cleaning the lens and preventing long-term dust accumulation that could blur the captured monitoring image and affect the security monitoring effect. However, based on practical experience in low-voltage engineering monitoring, while this device allows for angle adjustment in low-voltage rooms, it is not convenient for multi-directional monitoring of multiple neatly arranged low-voltage cabinets. The monitoring area is relatively limited, resulting in poor security performance.

[0004] Therefore, there is an urgent need to improve existing security monitoring devices for low-voltage engineering projects and provide a security monitoring device for low-voltage engineering projects with multi-directional monitoring functions. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by providing a reasonably designed, simple structured, and multi-directional monitoring device for low-voltage engineering security, thereby solving the problems existing in the prior art.

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

[0007] A security monitoring device for low-voltage electrical engineering includes a track plate and a monitoring probe. Two limiting rods are symmetrically fixedly installed at the upper and lower ends of the track plate. A movable plate is provided on the outer front side of the track plate, with its upper and lower ends slidably fitted onto the outer sides of the two limiting rods. A support plate is fixed to the outer front wall of the movable plate. A drive assembly is installed at one end of the support plate near the movable plate, and a traveling assembly is located below the drive assembly. A movable bracket is mounted on the other end of the support plate away from the movable plate, with a linkage plate fixedly connected to its bottom. The linkage plate is drive-connected to the drive assembly. The monitoring probe is mounted on the inner top of the movable bracket with an adjustable pitch angle via positioning bolts. A meshing bar extending in the left-right direction is provided at the bottom of the track plate. A traveling assembly for driving the movable plate left and right movement is located below the drive assembly, and the traveling assembly is drive-connected to both the meshing bar and the drive assembly.

[0008] Preferably, both the track plate and the movable plate have a U-shaped longitudinal section, and the movable plate is slidably sleeved on the outer front end of the track plate.

[0009] Preferably, the drive assembly includes a servo motor, an output shaft, an eccentric circle, and a first conical tooth. The servo motor is fixedly mounted on the support plate above one end near the moving plate. The output end of the servo motor is fixedly connected to the output shaft. An eccentric circle and a first conical tooth are fixedly sleeved on the outer side of the bottom end of the output shaft. The first conical tooth is located below the eccentric circle.

[0010] Preferably, the linkage plate has a through groove at the end away from the movable bracket, the eccentric circle is located in the through groove, and the connection point between the eccentric circle and the output shaft is located at the outer edge of the eccentric circle away from its center.

[0011] Preferably, the walking assembly includes a horizontal shaft, a gear, and a second conical tooth. The horizontal shaft bearing is installed inside the bottom end of the moving plate. One end of the horizontal shaft is fixedly connected to the gear, and the other end of the horizontal shaft is fixedly connected to the second conical tooth, which meshes with the first conical tooth.

[0012] Preferably, the gear is located on the inner side of the bottom of the track plate and meshes with the gear bar.

[0013] Preferably, an infrared thermometer is fixed above the front end of the monitoring probe, and a wireless transceiver is installed on the outer wall of the rear end of the monitoring probe.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] In this invention, when the monitoring device is in operation, the servo motor is activated, which uses the first and second conical teeth to control the rotation of the horizontal axis and gears. The meshing bar on the inner side of the bottom of the track plate controls the horizontal movement of the moving plate and the monitoring probe along the limit rod. At the same time, the rotating eccentric circle can squeeze and push the linkage plate to drive the movable bracket and the monitoring probe to make small left and right reciprocating deflections while moving. This facilitates multi-directional monitoring of multiple low-voltage cabinets arranged in the low-voltage room, making the monitoring more comprehensive and ensuring that each low-voltage cabinet can be effectively supervised, thus significantly improving security.

[0016] The length of the track plate and limit rod of this utility model can be customized according to the actual size of the low-voltage room to meet the actual monitoring and management needs. The infrared thermometer moves with the monitoring probe to facilitate temperature detection of each low-voltage cabinet in the low-voltage room. The detected temperature data can be transmitted to the monitoring terminal through a wireless transceiver to monitor the operational safety of the low-voltage cabinet in real time and to respond quickly and handle the situation in case of danger.

[0026] like Figure 1-5 As shown in the figure, the low-voltage engineering security monitoring device of this utility model includes a track plate 1 and a monitoring probe 11. Two limiting rods 2 are symmetrically fixedly installed at the upper and lower ends of the track plate 1. A movable plate 4 is provided on the outer front side of the track plate 1. The upper and lower ends of the movable plate 4 are respectively slidably sleeved on the outer side of the two limiting rods 2. A support plate 5 is fixed on the outer wall of the front end of the movable plate 4. A drive assembly 6 is installed at one end of the support plate 5 near the movable plate 4. A walking assembly 7 is provided below the drive assembly 6. A movable bracket 8 is mounted on the bearing at the other end of the support plate 5 away from the movable plate 4. A linkage plate 9 is fixedly connected to the bottom of the movable bracket 8. The linkage plate 9 is connected to the drive assembly 6 in a transmission connection. A positioning bolt 10 is threaded on the outer wall of the top of the movable bracket 8. The monitoring probe 11 is mounted on the inner side of the top of the movable bracket 8 with adjustable pitch angle through the positioning bolt 10. A meshing bar 3 extending in the left and right direction is provided at the bottom of the track plate 1. A walking assembly 7 for driving the movable plate 4 and the monitoring probe 11 to move left and right is provided below the drive assembly 6. The walking assembly 7 is connected to the meshing bar 3 and the drive assembly 6 in a transmission connection.

[0027] As a preferred embodiment, based on the above structure, an infrared thermometer 12 is fixed above the front end of the monitoring probe 11, and a wireless transceiver 13 is installed on the outer wall of the rear end of the monitoring probe 11.

[0028] As a preferred embodiment, based on the above structure, both the track plate 1 and the movable plate 4 have a U-shaped longitudinal section, and the movable plate 4 is slidably sleeved on the outer front end of the track plate 1; the bottom inner side of the track plate 1 is integrally formed with a meshing bar 3 of the same length.

[0029] In this embodiment, the meshing bar 3 facilitates the stable movement and adjustment of the moving plate 4 along the limiting rod 2.

[0030] As a preferred embodiment, based on the above structure, the drive assembly 6 further includes a servo motor 61, an output shaft 62, an eccentric circle 63, and a first conical tooth 64. The servo motor 61 is fixedly mounted on the support plate 5 above one end near the moving plate 4. The output end of the servo motor 61 is fixedly connected to the output shaft 62. The eccentric circle 63 and the first conical tooth 64 are fixedly sleeved on the outer side of the bottom end of the output shaft 62. The first conical tooth 64 is located below the eccentric circle 63.

[0031] As a preferred embodiment, based on the above structure, a through groove 14 is further provided inside the end of the linkage plate 9 away from the movable bracket 8, and the eccentric circle 63 is movably located in the through groove 14. The connection point between the eccentric circle 63 and the output shaft 62 is located at the outer edge of the eccentric circle 63 away from its center.

[0032] In this embodiment, when the control output shaft 62 drives the eccentric circle 63 to rotate, the eccentric circle 63 can squeeze and push the linkage plate 9 to drive the movable bracket 8 and the monitoring probe 11 to move while making small left and right reciprocating deflections, which facilitates multi-directional monitoring of multiple low-voltage cabinets arranged in the low-voltage room, making the monitoring more comprehensive.

[0033] In a preferred embodiment, based on the above structure, the walking assembly 7 further includes a horizontal shaft 71, a gear 72, and a second conical tooth 73. The horizontal shaft 71 is bearing-mounted inside the bottom end of the moving plate 4. One end of the horizontal shaft 71 is fixedly connected to the gear 72, which is located on the inner side of the bottom of the track plate 1 and meshes with the meshing bar 3. The other end of the horizontal shaft 71 is fixedly connected to the second conical tooth 73, which meshes with the first conical tooth 64.

[0034] In this embodiment, when the output shaft 62 and the first conical tooth 64 rotate, the second conical tooth 73, which meshes with the first conical tooth 64, can control the rotation of the horizontal shaft 71 and the gear 72. With the cooperation of the meshing bar 3, the moving plate 4 and the monitoring probe 11 can be controlled to move horizontally along the limit rod 2.

[0035] The working principle of this utility model is as follows:

[0036] In use, the track plate 1 is first fixed to a suitable position on the wall of the low-voltage room using expansion bolts. During the monitoring and management of the low-voltage room, the servo motor 61 above the support plate 5 can be started to control the output shaft 62, the eccentric circle 63 and the first conical tooth 64 to rotate synchronously. At this time, the second conical tooth 73, which meshes with the first conical tooth 64, can drive the horizontal shaft 71 and the gear 72 to rotate. The meshing bar 3 on the inner side of the bottom of the track plate 1 can control the moving plate 4 and the monitoring probe 11 to move horizontally along the limit rod 2. At the same time, the rotating eccentric circle 63 can squeeze and push the linkage plate 9, so that the movable bracket 8 and the monitoring probe 11 can move horizontally and also make small reciprocating deflections to the left and right. This makes it easier to monitor multiple low-voltage cabinets arranged in the low-voltage room from multiple angles and directions. The monitoring is more comprehensive, and each low-voltage cabinet can be effectively supervised, and the security can be significantly improved.

[0037] While monitoring, the infrared thermometer 12 can also follow the movement of the monitoring probe 11 to facilitate temperature detection of each low-voltage cabinet in the low-voltage room. The detected temperature data can be transmitted to the monitoring terminal through the wireless transceiver 13 and existing technology to monitor the operational safety of the low-voltage cabinet in real time and to respond quickly and handle the situation in time when a dangerous situation occurs.

[0038] It should be noted that the lengths of the track plate 1 and the limit rod 2 can be customized according to the actual size of the low-voltage room to meet the actual monitoring and management needs. The power supply method, specific structure and working principle of the monitoring probe 11, infrared thermometer 12 and wireless transceiver 13 in this case are all mature existing technologies, so they will not be described in detail.

[0039] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any equivalent changes, modifications, substitutions, and variations made by those skilled in the art based on the concept of this utility model and on the basis of existing technology through logical analysis, reasoning, or limited experiments shall be within the scope of protection defined by the claims.
