Description

Technical Field

[0001] This utility model relates to a safe electrical device, specifically a safe electrical device for highways. Background Technology

[0002] Currently, in mains-connected circuits, if a person or animal touches a live wire while the circuit is grounded, it can cause electric shock, potentially resulting in injury or death. Furthermore, when a live wire touches a grounded metal surface, it can leak electricity and generate an electric arc, which can easily lead to serious accidents such as fires and explosions.

[0003] On highways, electrical facilities are mostly located in public places such as toll booths and service stations. If a short circuit occurs in one circuit, it can easily paralyze the entire circuit. It is necessary to check all electrical equipment one by one, which is undoubtedly a huge task.

[0004] Therefore, those skilled in the art have provided a highway safety electrical device to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to provide a safe electrical device for highways to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A highway safety electrical device includes a device body, which includes a device output terminal, a device input terminal, and a heat dissipation hole. The device output terminal can be optionally connected to an electrical equipment plug. The device input terminal is connected to an external power supply. The external power supply wire includes a ground wire, a neutral wire, and a live wire. The ground wire, neutral wire, and live wire are connected to the copper contacts of each interface of the device output terminal. The live wire is equipped with a circuit breaker.

[0008] Preferably, the upper coil of the circuit breaker is connected to the live wire. The coil is equipped with a metal floating block, a contact rod, and a floating spring. The bottom of the metal floating block is fixedly connected to the floating spring and the contact rod. The floating spring surrounds the side of the contact rod. The bottom end of the floating spring is fixedly connected to a fixed plate. The contact rod is clearance-fitted to the fixed plate. The fixed plate is fixedly connected to the device body. The wire at the tail of the coil touches a conductive metal sheet. The conductive metal sheet is rotatably connected to the device body through a wire connecting shaft.

[0009] Preferably: the wire connecting shaft is connected to the live wire, the conductive metal sheet is in contact with one end of the connecting rod, the connecting rod is rotatably connected to the device body through the connecting rod rotating shaft, the conductive metal sheet is connected to the other end of the connecting rod through spring one, the connecting rod is connected to spring two through spring connecting shaft, spring two is connected to the device body through spring fixing shaft, the connecting rod tail end slot is provided with a control rod, the other end of the control rod is connected to the eccentric position of the control cam, the control cam is rotatably connected to the device body through cam rotating shaft, the control cam is provided with a manual control block, and the control cam is clearance-fitted with the upper and lower limit blocks.

[0010] Preferred configuration: A power supply is connected to the input terminal of the device, and a plug for the electrical equipment is connected to the output terminal of the device. The electrical equipment is connected in parallel to the circuit. When a short circuit occurs in the electrical equipment, the current in the live wire will increase sharply, thereby generating a larger magnetic field in the coil. The magnetic field pulls the metal floating block closer to the fixed plate. The metal floating block is limited in the coil by the floating spring. The touch rod will then contact the connecting rod downwards, causing the right side of the connecting rod to move down. Spring 1 contracts, and Spring 2 stretches. The control rod and the pull control cam rotate clockwise. When the control rod is on the left side of the cam rotation axis, the direction of force on the control rod changes. During the recovery process of Spring 1 and Spring 2, the control rod will pull the connecting rod to rotate counterclockwise around the connecting rod rotation axis, causing the connecting rod to exert pressure on the conductive metal plate and disconnect it from the wire at the tail of the coil, thereby disconnecting the live wire. When it is necessary to restore the circuit, the circuit can be restored simply by manually rotating the control cam counterclockwise.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This new type of circuit provides semi-isolation between local power supply and the main circuit. When a short circuit occurs in the local power supply, the circuit can be effectively disconnected, preventing the main circuit fuse from blowing directly and causing the entire circuit to fail.

[0013] 2. This new type of circuit allows for manual control of the connection status of local circuits, making it convenient to use and to troubleshoot circuits based on the status of the manual control block. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-5 In this embodiment of the utility model, a highway safety electrical device includes a device body 1. The device body 1 includes a device output terminal 21, a device input terminal 22, and a heat dissipation hole 23. The device output terminal 21 can be optionally connected to an electrical equipment plug 2. The device input terminal 22 is connected to an external power supply. The external power supply wire includes a ground wire 24, a neutral wire 25, and a live wire 26. The ground wire 24, neutral wire 25, and live wire 26 are connected to the copper plates of each interface of the device output terminal 21. The live wire 26 is equipped with a circuit breaker 3.

[0022] The upper coil 301 of the circuit breaker 3 is connected to the live wire 26. The coil 301 contains a metal floating block 304, a contact rod 305, and a floating spring 306. The bottom of the metal floating block 304 is fixedly connected to the floating spring 306 and the contact rod 305. The floating spring 306 surrounds the side of the contact rod 305, and its bottom end is fixedly connected to a fixing plate 318. The contact rod 305 is clearance-fitted to the fixing plate 318. The fixing plate 318 is fixedly connected to the device body 1. The tail wire of the coil 301 contacts a conductive metal sheet 303. The conductive metal sheet 303 is rotatably connected to the device body 1 via a wire connecting shaft 302. The wire connecting shaft 302 is connected to the live wire 26. Metal sheet 303 contacts one end of connecting rod 307. Connecting rod 307 is rotatably connected to device body 1 via connecting rod rotation shaft 309. Conductive metal sheet 303 is connected to the other end of connecting rod 307 via spring 1 308. Connecting rod 307 is connected to spring 2 312 via spring connecting shaft 311. Spring 2 312 is connected to device body 1 via spring fixing shaft 310. Control rod 313 is provided in the slot at the tail end of connecting rod 307.

Control cam 314 is provided with manual control block 317. Control cam 314 is clearance-fitted with upper and lower limit blocks 316.

[0023] The working principle of this utility model is as follows: A power supply is connected to the device input terminal 22, and a power device plug 2 is connected to the device output terminal 21. The power device is connected in parallel to the circuit. When a short circuit occurs in the power device, the current in the live wire 26 will increase sharply, thereby causing the coil 301 to generate a larger magnetic field. The magnetic field pulls the metal floating block 304 closer to the fixed plate 318. The metal floating block 304 is limited in the coil 301 by the floating spring 306. The touch rod 305 will then contact the connecting rod 307 downwards, causing the connecting rod 307 to move downwards to the right. Spring 1 308 contracts, and spring 2 312 stretches, controlling the... The lever 313 rotates clockwise with the pull control cam 314. When the control lever 313 is to the left of the cam rotation shaft 315, the force direction of the control lever 313 changes. During the recovery process of spring 1 308 and spring 2 312, the control lever 313 will pull the connecting rod 307 to rotate counterclockwise around the connecting rod rotation shaft 309. This causes the connecting rod 307 to exert pressure on the conductive metal sheet 303 and disconnect it from the wire at the tail of the coil 301, thereby disconnecting the live wire 26. When it is necessary to restore the circuit, the circuit can be restored simply by manually rotating the control cam 314 counterclockwise through the manual control block 317.
