For example, the embodiments may have various modifications and various forms, and it is to be understood that the scope of the claims of the present utility model includes equivalents capable of realizing the technical idea.
As shown in fig. 1 and 2, the present embodiment is implemented by the following technical solutions: the safety belt comprises a safety belt body 1, wherein the safety belt body 1 is connected with two safety ropes 2, the tail end of each safety rope 2 is connected with a safety hook 3, the safety belt body 1 is provided with a connecting buckle 4, a main power supply 5 and a signal transmitting device 16, the main power supply 5 supplies power for an alarm circuit, the connecting buckle 4 serves as a switch 6 of the alarm circuit, the alarm circuit is electrified after buckling, and the signal transmitting device 16 transmits an alarm signal when the alarm circuit is electrified and the safety hook 3 is not hung on a structure 17.
The alarm circuit comprises a main line 7, wherein the main line 7 is connected with a main power supply 5 through a switch 6, the main line 7 and the main power supply 5 can form a loop, and a protection resistor 8 is arranged on the main line 7; the main line 7 is connected with two relays 12 in parallel, and the coil signal input end of each relay 12 is connected with the main line 7 through a safety hook contact 10 and a NOT gate 11; the alarm circuit also comprises a signal wire 9 connected with the main wire 7, wherein the signal wire 9 is divided into two paths connected in parallel, each path is connected with a normally closed contact 15 of one relay 12, and the normally closed contacts 15 of the two relays 12 are both connected with signal ports of a signal transmitting device 16; the signal transmission device 16 is provided with a power supply.
In this embodiment, the main power supply 5 is a rechargeable lithium battery or a plurality of 5 # batteries connected in series.
In this embodiment, the two contacts are opened when the safety hook 3 is opened, and at this time, the two parts of the safety hook 3 are insulated.
The working principle of the utility model is as follows:
the connecting buckle 4 is used as a switch 6 of the alarm circuit, the connecting buckle 4 is buckled after the worker wears the alarm circuit, namely the switch 6 is closed, and the alarm circuit is electrified. At this time, the safety hook 3 is not opened and hung on an adjacent structure 17, the safety hook contact 10 is in a closed state, the non-gate circuit 11 is not conducted, no electric signal is input to the coil signal input end of the relay 12, the coil 13 is not electrified, the normally open contact 14 and the normally closed contact 15 are in an initial state, the normally closed contact 15 of the relay 12 is conducted, the electric signal reaches a signal port of the signal transmitting device 16 through the signal wire 9 and the two normally closed contacts 15 which are connected in parallel, the signal transmitting device 16 transmits an alarm signal and emits a beep, the alarm signal is received by a supervisory personnel on the ground through receiving equipment, the alarm signal is used for reminding the supervisory personnel, and the beep is used for reminding the high-altitude operation personnel that the safety rope 2 is not hung at this time. Since the two relays 12 are connected in parallel, the signal transmitting device 16 can obtain an electric signal and transmit an alarm signal and generate a beeping sound as long as one safety hook 3 is not hung correspondingly.
When the safety hook 3 is hung on an adjacent structure 17, the safety hook 3 is opened once and then closed again, the corresponding safety hook contact 10 in the alarm circuit is opened, the non-gate circuit 11 sends an electric signal to the relay 12, the coil 13 is electrified, so that the normally open contact 14 and the normally closed contact 15 are in a switching state, namely the normally open contact 14 is closed, the normally closed contact 15 is opened, the main line 7, the normally open contact 14 and the coil 13 form a loop to be always electrified, the coil 13 is always electrified, the normally open contact 14 is always in a closed state, the normally closed contact 15 is always in an open state, and the signal wire 9 cannot send an electric signal to a signal port of the signal sending device 16 through the normally closed contact 15.
