Description

Technical Field

[0001] This utility model relates to the technical field of secondary safety measures tools for relay protection, specifically to an intelligent secondary safety measures monitoring device based on low-power Bluetooth communication. Background Technology

[0002] During relay protection maintenance, secondary safety measures are implemented before on-site maintenance work, which requires disconnecting some protective pressure plates. These are temporary safety measures that need to be implemented and must be restored promptly after the work is completed. To prevent accidental restoration of these isolated measures during work, and to clearly identify which measures need to be restored after the work is completed, clear marking tools are needed. Currently, secondary safety measures for secondary protective pressure plates commonly use insulating tape. Insulating tape is not only inconvenient to use and prone to peeling, but also relies on manual visual inspection, which may lead to problems going unnoticed in time, affecting equipment and personal safety, and even causing accidents. Utility Model Content

[0005] The housing is a box-type structure with an open top. The battery and the micro switch are electrically connected to the PCB board. The detection hole is connected to the mounting slot and corresponds to the micro switch. The sensing end of the micro switch extends outward through the detection hole. The magnetic block is embedded and fixed in the slot.

[0006] It also includes a first card plate and a second card plate that are disposed opposite to each other on the inner wall of the bottom of the housing. Both the first card plate and the second card plate are arc-shaped structures, and the side end of the first card plate or the second card plate corresponds to the limiting port.

Detailed Implementation

[0015] like Figure 1-4 As shown, this utility model provides an intelligent secondary safety monitoring device based on low-power Bluetooth communication, including a housing 1 with an open top, a limiting port 2 on one side of the housing 1, a mounting groove 3 on the outer wall of the other side of the housing 1, a PCB board 4 and a battery 5 in the mounting groove 3, a micro switch 6 on the PCB board 4, a detection hole 7 at the top of the housing 1, a slot 8 at the top of the side wall of the housing 1, and a magnetic block 9 in the slot 8. The housing 1 is a box-type structure with an open top. The battery 5 and the micro switch 6 are electrically connected to the PCB board 4. The detection hole 7 is connected to the mounting groove 3 and corresponds to the micro switch 6. The sensing end of the micro switch 6 extends outward through the detection hole 7. The magnetic block 9 is embedded and fixed in the slot 8.

[0016] With attachment Figure 1From the perspective of the viewpoint, the housing 1 is a rectangular box structure with an opening at the top. A limiting port 2 is provided on the front side of the housing 1, and the limiting port 2 is located on the front and right sides of the housing 1. The PCB board 4 and the battery 5 are installed on the outer wall of the rear side of the housing 1, and the magnetic block 9 is embedded and fixed in the slot 8 at the top of the housing 1.

[0017] like Figure 4 As shown, the secondary pressure plate of the relay protection mainly consists of two terminals installed in the distribution box and a pressure plate installed between the two terminals. One end of the pressure plate is hinged to one of the terminals and the other end is snapped to the other terminal. When one end of the pressure plate is detached from one of the terminals, the relay protection is in the off state.

[0018] Battery 5 is used to power PCB board 4. An alarm module can be set on PCB board 4, such as alarm by sound and light, or wireless communication module to directly send the alarm to the terminal device of the staff. The choice is made according to the needs and is not limited here.

[0019] When this utility model is in use, after the pressure plate is disconnected, the housing 1 is fastened to the two power terminals through the upper opening. The end of the pressure plate that is detached from the power terminals extends outward from the limiting port 2 on one side of the housing 1. The magnetic block 9 at the opening end of the housing 1 is attracted to the inner wall of the distribution box. The micro switch 6 on the PCB board 4 is pressed against the inner wall of the distribution box, and the sensing end of the micro switch 6 is in a retracted state.

[0020] One end of the pressure plate is detached from the power terminal and is outside the housing 1. Without removing the housing 1, the pressure plate cannot be closed, effectively serving as a marker and preventing the pressure plate from closing. When closing the pressure plate, the housing 1 must first be removed from the power terminal. After the housing 1 is removed, the sensing end of the micro switch 6 is no longer pressed against the inner wall of the distribution box, changing from a retracted state to an extended state, triggering the corresponding alarm module to sound an alarm.

[0021] This device uses a snap-fit ​​and magnetic block 9 for installation, which is simple to operate and convenient to use. When the device is removed, the status change of the sensing micro switch 6, together with the corresponding alarm module, can remind the staff in real time without relying on the staff's visual observation, thus reducing the staff's labor intensity and improving the staff's work efficiency.

[0022] like Figure 1 As shown, it also includes a first locking plate 10 and a second locking plate 11 disposed opposite to each other on the inner wall of the bottom of the housing 1. Both the first locking plate 10 and the second locking plate 11 are arc-shaped structures, and the side end of the first locking plate 10 or the second locking plate 11 corresponds to the limiting port 2.

[0023] The first clamping plate 10 and the second clamping plate 11 are arc-shaped plates arranged opposite each other, located on the inner wall of the bottom of the housing 1, and respectively on the inner side of the left and right inner walls of the housing 1. The power connection posts are generally circular. After the housing 1 is fastened onto the two power connection posts, the two power connection posts are limited between the first clamping plate 10 and the second clamping plate 11, making the installation more stable, the positioning more accurate, and the use more convenient.

[0024] like Figure 2 As shown, it also includes a side cover 12 that fits onto the mounting groove 3.

[0025] The side cover 12 can protect the PCB board 4 and the battery 5.

[0026] like Figure 3 As shown, the mounting groove 3 includes a rectangular groove 13, a positioning protrusion 14 disposed in the rectangular groove 13, and a circular groove 15 disposed on one side of the rectangular groove 13. One side of the rectangular groove 13 is connected to the circular groove 15. The PCB board 4 is installed in the rectangular groove 13, and the battery 5 is installed in the circular groove 15.

[0027] The PCB board 4 is provided with positioning holes that fit the positioning protrusion 14. The PCB board 4 is positioned by the positioning protrusion 14 and can be easily installed in the rectangular groove 13. The battery 5 is installed in the circular groove 15, making installation more convenient.
