Description

Technical Field

[0001] This utility model relates to the field of safety protection technology for electrical training equipment, specifically an automatic power-off protection device for an electrical skills assessment and practical platform. Background Technology

[0002] The electrician skills assessment and practice platform is a training platform specifically designed for electrician vocational skills training and assessment. It aims to help trainees conduct practical training and evaluation of their electrician skills by simulating real electrical environments and equipment operation. Because electrician practice involves handling high-voltage electricity, trainees may encounter dangerous situations such as wiring errors or insulation damage during training or assessment, leading to leakage or short circuits. To ensure operator safety and prevent electric shock accidents, the electrician skills assessment and practice platform is usually equipped with automatic power-off protection devices.

[0003] The existing technology has the following shortcomings:

[0004] 1. The maintenance casing of the automatic power-off protection device in the existing electrical skills assessment and practice platform is usually fixed with screws. When it is necessary to remove the maintenance casing to inspect the inside of the device, it is often necessary to use external tools such as screwdrivers, which is quite troublesome. The ease of maintenance of the device can be further improved.

[0005] 2. The existing automatic power-off protection device of the electrician skills assessment platform lacks a structure to prevent the platform power cable from detaching (it mainly fixes the cable by crimping). When the platform power cable is accidentally pulled by external forces (such as pulling caused by the trainee's misoperation), it is easy to detach from the power-off protection device. The device's anti-detachment effect on the platform power cable can be further improved. Utility Model Content

[0006] The purpose of this utility model is to provide an automatic power-off protection device for an electrical skills assessment and practical platform, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an automatic power-off protection device for an electrical skills assessment and practical platform, comprising a fixed shell, a maintenance shell on one side of the fixed shell, a display screen and indicator lights on one side of the maintenance shell, a cable on the fixed shell, a fixing component between the fixed shell and the maintenance shell, a fixing ring on the top of the fixed shell, a support block on the fixing ring, an anti-detachment block on the support block, a connecting ring on the cable, and an anti-slip ring on the connecting ring;

[0009] As a preferred embodiment of this utility model, one end of the connecting rod is rotatably mounted on one side of the fixed shell, and both sides of the other end of the connecting rod are fixedly mounted with fixing blocks.

[0010] As a preferred embodiment of this utility model, the connecting port is adapted to the connecting rod, and the two sets of moving ports are respectively adapted to the two sets of fixed blocks.

[0011] As a preferred technical solution of this utility model, one end of the connecting rod is snapped and passes through the connecting port, and the two sets of fixing blocks pass through the two sets of moving ports respectively and are perpendicular to the moving ports. The fixing blocks are in contact with the maintenance shell, and magnets are embedded on the contact side of the two sets of fixing blocks and the corresponding position of the maintenance shell. The fixing blocks and the magnets of the maintenance shell are magnetically attracted to each other. Four sets of fixing components are provided on the maintenance shell.

[0012] As a preferred embodiment of this utility model, the fixing ring is fixedly installed on the top of the fixing shell and corresponds to the wiring port position of the fixing shell, and one end of the cable passes through the fixing ring and extends into the wiring port.

[0013] As a preferred embodiment of this utility model, the connecting ring is fixedly installed on the cable and the bottom of the connecting ring is in contact with the top of the fixing ring, and the anti-slip ring is fixedly installed on the top of the connecting ring and the anti-slip ring is made of soft silicone.

[0014] As a preferred technical solution of this utility model, support blocks are fixedly installed on both sides of the fixing ring, and anti-detachment blocks are rotatably installed on the top of the two sets of support blocks. The two sets of anti-detachment blocks are respectively placed on both sides of the top of the connecting ring, and two sets of fixing rings are provided on the top of the fixing shell.

[0015] Compared with the prior art, this utility model provides an automatic power-off protection device for an electrical skills assessment and practical platform, which has the following beneficial effects:

[0016] 1. The automatic power-off protection device of the electrician skills assessment and practice platform, by setting a fixed component, when it is necessary to inspect the inside of the device, rotate the connecting rod to align the fixed block with the moving port, and move the inspection shell outward to disassemble it from the connecting rod and the fixed block to complete the disassembly of the inspection shell. At this time, the inside of the fixed shell can be inspected. The above operation is reversed to complete the installation of the inspection shell. This structure makes the disassembly and assembly of the inspection shell convenient without the need for external tools, and thus facilitates the maintenance of the device.

[0017] 2. This automatic power-off protection device for an electrical skills assessment and practical platform, by setting a fixing ring, a support block, an anti-detachment block, a connecting ring, and an anti-slip ring, can limit and fix the cable when it is accidentally pulled by the outside.

[0026] The fixing component 6 includes a connecting rod 601, a fixing block 602, a magnet block 603, a connecting port 604, and a moving port 605. The connecting rod 601 is provided on one side of the fixing shell 1, the fixing block 602 is provided on the connecting rod 601, and the magnet block 603 is provided on the fixing block 602. The connecting port 604 is provided on one side of the maintenance shell 2. The connecting port 604 facilitates the connection between the connecting rod 601 and the maintenance shell 2. Moving ports 605 are provided on both sides of the inner wall of the connecting port 604.

[0027] In this embodiment, one end of the connecting rod 601 is rotatably mounted on one side of the fixed housing 1, and the other end of the connecting rod 601 is fixedly mounted on both sides with fixing blocks 602.

[0028] Specifically, the connecting rod 601 facilitates the connection between the housing 2 and the fixed housing 1 for inspection;

[0029] In this embodiment, the connection port 604 is adapted to the connecting rod 601, and the two sets of movable ports 605 are adapted to the two sets of fixed blocks 602 respectively.

[0030] Specifically, the movable port 605 allows the fixing block 602 to pass through the maintenance housing 2;

[0031] In this embodiment, one end of the connecting rod 601 is snapped into and passes through the connecting port 604. The two sets of fixing blocks 602 pass through the two sets of moving ports 605 respectively and are perpendicular to the moving ports 605. The fixing blocks 602 are attached to the inspection shell 2, and magnets 603 are embedded on the attached sides of the two sets of fixing blocks 602 and the corresponding positions of the inspection shell 2. The fixing blocks 602 and the magnets 603 on the inspection shell 2 are magnetically attracted to each other. Four sets of fixing components 6 are provided on the inspection shell 2.

[0032] Specifically, the fixing block 602 can limit and fix the inspection shell 2;

[0033] In this embodiment, the fixing ring 7 is fixedly installed on the top of the fixing shell 1 and corresponds to the wiring port position of the fixing shell 1. One end of the cable 5 passes through the fixing ring 7 and extends into the wiring port.

[0034] Specifically, the retaining ring 7 facilitates the installation of the support block 8;

[0035] In this embodiment, the connecting ring 10 is fixedly installed on the cable 5 and the bottom of the connecting ring 10 is in contact with the top of the fixing ring 7. The anti-slip ring 11 is fixedly installed on the top of the connecting ring 10 and the anti-slip ring 11 is made of soft silicone.

[0036] Specifically, the connecting ring 10 facilitates the connection between the cable 5 and the support block 8;

[0037] In this embodiment, support blocks 8 are fixedly installed on both sides of the fixing ring 7, and anti-detachment blocks 9 are rotatably installed on the top of the two sets of support blocks 8. The two sets of anti-detachment blocks 9 are respectively placed on both sides of the top of the connecting ring 10, and two sets of fixing rings 7 are provided on the top of the fixing shell 1.

[0038] Specifically, the anti-detachment block 9 prevents the connecting ring 10 from moving upward, thus preventing the cable 5 from detaching from the fixing ring 7.

[0039] The working principle and usage process of this utility model are as follows: The automatic power-off protection device is installed in a suitable position. At this time, the automatic power-off protection device is electrically connected to the power supply of the electrician skills assessment platform through cable 5. When the automatic power-off protection device detects leakage or short circuit in the platform power supply, it will automatically cut off the power. When it is necessary to inspect the inside of the device later, rotate each set of connecting rods 601 in sequence to align the fixing block 602 with the moving port 605, and move the inspection shell 2 outward to disassemble it from the connecting rods 601 and the fixing block 602. At this time, the inside of the fixing shell 1 can be inspected. The above operation is reversed to complete the installation of the inspection shell 2, which is more convenient. Moreover, due to the magnetic attraction between the fixing block 602 and the magnet 603 on the inspection shell 2, the fixing block 602 will not rotate randomly when it is perpendicular to the moving port 605. The fixing block 602 can limit and fix the inspection shell 2. This structure makes the disassembly and assembly of the inspection shell 2 without the need for external tools, which is more convenient and facilitates the maintenance of the device.

[0040] When cable 5 is accidentally pulled externally, the anti-detachment block 9 limits and fixes the connecting ring 10, thus limiting and fixing cable 5. The anti-slip ring 11 prevents the anti-detachment block 9 from sliding or rotating freely after being placed on the connecting ring 10, thereby preventing cable 5 from detaching from the automatic power-off protection device. Furthermore, during the installation of cable 5, rotating the anti-detachment block 9 to one side of the connecting ring 10 will not affect the normal passage of cable 5 through the fixing ring 7 for installation. This structure can further improve the anti-detachment effect of the automatic power-off protection device on the power supply cable 5 of the electrician skills assessment practice platform.

[0041] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
