[0056] Embodiment 2:

[0057] The following is the working principle of the overcurrent protector 5 of the early warning device of the utility model:

[0058] Initial state, such as Figure 2As shown, the conductive rod 28 is pressed on the push-on / off switch 21. When the push-on / off switch 21 is pressed, the sound and light alarm 20 is in the disconnected state. When the push-on / off switch 21 is not pressed, the push-on / off switch 21 is automatically turned on by elastic force.

[0059] At this time, the compression spring 23 is in a compressed state, and the fuse 29 is pressed against the conductive rod 28 and is limited by the plug cap 32. The first contact end of the fuse 29 is in electrical contact with the first elastic electrode 31, and the first elastic electrode 31 is electrically connected to the third contact electrode 16 through the circuit, and the third contact electrode 16 is electrically connected to the left terminal group 15.

[0060] When there is a current in the circuit that exceeds the load of the fuse 29, the fuse 29 is blown immediately, the compression spring 23 lifts the conductive rod 28, and the conductive rod 28 is separated from the right terminal group 24, thereby disconnecting the circuit.

[0061] At this time, the insulating sleeve outside the conductive rod 28 moves upward synchronously with the conductive rod 28 , and finally, the conductive layer 27 on one side of the insulating sleeve and the two second elastic electrodes 30 make the circuit of the two second elastic electrodes 30 conductive.

When the pressure-holding on-off switch 21 is not pressed and is turned on, and when the 1# elastic electrode and the 2# elastic electrode are turned on, the LED 19 of the sound and light alarm 20 lights up and the speaker emits an alarm sound.

[0064] When the fuse 29 needs to be replaced, remove the overcurrent protector 5, open the front cover of the overcurrent protector 5, take out the U-shaped structural seat 22 and the emergency power supply unit 11, unscrew the plug 32 and take it out, then take out the melted fuse, and if there are debris, clear the debris. Take a new fuse and put it into the sliding cavity, screw on the plug 32, and then put it back into the shell. Put the overcurrent protector 5 back into the inverted U-shaped structural member 4.

[0065] In summary, the early warning device of the utility model is provided with a circuit breaker protection mechanism to prevent excessive current in the circuit, and the sound and light alarm is used for alarm. The overcurrent protector of the utility model is detachable, and the fuse is convenient to replace. The early warning device of the utility model improves the safety of outdoor operations.
