Description
Technical field
The utility model belongs to transmission of electricity utility appliance field, the nearly electric safety early warning device of especially a kind of construction machinery.
Background technology
The big machineries such as crane touch hi-line accident, coming from driver and lack electrical safety knowledge and driver at the scene, concentrating in hanging thing, and have ignored the safe distance kept different electric pressure.The nearly electric safety early warning device of development construction machinery, is contained in mechanical arm end, when the risk distance close to high voltage alive equipment, sends suggestive chimes of doom in time.Prevent from touching broken height line ball by mistake or causing hi-line discharge accident.To guarantee the person, equipment and power supply safety.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art part, provides a kind of and gathers electric signal by electrode and effectively avoid the nearly electric safety early warning device of the construction machinery of construction accident.
The purpose of this utility model is achieved through the following technical solutions:
The nearly electric safety early warning device of a kind of construction machinery, comprise sensor and alarm, described sensor is arranged on the arm of construction machinery crane, this sensor comprises electrode and wireless frequency modulation signal projector, and the output terminal of electrode is connected with wireless frequency modulation signal projector input end by internal control circuit;
Alarm in installing be provided with wireless frequency modulation signal receiver and surface-mounted integrated circuit, on surface-mounted integrated circuit, integrated installation has demoder, controller and LED light, the input end of wireless frequency modulation signal receiver is connected with wireless frequency modulation signal projector output terminal is long-range, the output terminal of wireless frequency modulation signal receiver is connected with the decoder input on surface-mounted integrated circuit, this decoder output is connected with controller input end, controller output end connects a LED light respectively by control circuit, and controller output end is also connected with liquid crystal display, hummer.
And described liquid crystal display, hummer are positioned on alarm.
And described sensor is positioned at arm and closes on a side of alive circuit.
And described alarm is hand-held alarm.
And described alarm is arranged in construction machinery crane pilothouse.
And described electrode is cylinder electrode.
Advantage of the present utility model and good effect are:
1, the utility model is by electrode sample, the result of measurement is converted into range information, by telecommunication network, the electric signal of collection is sent to alarm, by sound, optical, electrical instruction, realize reporting to the police, information discrimination is high, is the new security technology products of another item in safety installations.
2, the utility model utilizes electrostatic induction technology, develops a series of " charged display ", " charged instruction ", utilizes high-tension line field intensity, induced potential on a sensor.As signal alarm, can according to the different voltage of high-tension line, produce different field intensity, adjust different alarm distances, because electrostatic induction is different from electromagnetic induction, it is relevant with line facility voltage, has nothing to do with line facility load current, even unloaded, charging circuit, can obtain corresponding inductive energy (signal) too, reliability is high.
Accompanying drawing explanation
Fig. 1 is the utility model schematic block circuit diagram.
Embodiment
Below in conjunction with drawings and Examples, further illustrate the utility model, following embodiment is illustrative, is not determinate, can not limit protection scope of the present invention with following embodiment.
The nearly electric safety early warning device of a kind of construction machinery, comprise sensor and alarm, described sensor is arranged on the arm of construction machinery crane, being positioned at arm closes on a side of alive circuit, this sensor comprises cylinder electrode and wireless frequency modulation signal projector, the output terminal of cylinder electrode is connected with wireless frequency modulation signal projector input end, when electrode close to or when entering High Voltage electric field, electrode is by high-voltage signal collection and be sent to wireless frequency modulation signal projector, then sends by wireless frequency modulation signal projector is long-range;
Alarm in installing be provided with wireless frequency modulation signal receiver and surface-mounted integrated circuit, on surface-mounted integrated circuit, integrated installation has demoder, controller and LED light, the input end of wireless frequency modulation signal receiver is connected with wireless frequency modulation signal projector output terminal is long-range, the output terminal of wireless frequency modulation signal receiver is connected with the decoder input on surface-mounted integrated circuit, this decoder output is connected with controller input end, controller output end connects a LED light respectively by control circuit, and controller output end is also connected with liquid crystal display, hummer.
Alarm in installing be provided with wireless frequency modulation signal receiver and surface-mounted integrated circuit, on surface-mounted integrated circuit, integrated installation has demoder, controller and LED light, the input end of wireless frequency modulation signal receiver is connected with wireless frequency modulation signal projector output terminal is long-range, the output terminal of wireless frequency modulation signal receiver is connected with the decoder input on surface-mounted integrated circuit, this decoder output is connected with controller input end, controller output end connects a LED light respectively by control circuit, controller output end is also connected with liquid crystal display, hummer, alarm also can be able to be arranged in construction machinery crane pilothouse by site operation personnel are hand-held.
Principle of work of the present utility model is:
Crane (Sensor section) close to or when entering High Voltage electric field, electric signal is sent to alarm, alarm sends obvious acousto-optic warning signal immediately, liquid crystal display demonstrates " having electricity " word and symbol simultaneously, warning operator shut-down operation, this prevents one of crane important technical safety measures of by mistake touching hi-line.
This device sensor mounting location does not have randomness, and should consider on-the-spot ultra-high-tension power transmission line height, crane putting position, sensor can not be blocked, shield by the electric conductor of suspension arm of crane or grounding body.And the position of the most accessible high-voltage conducting wires when being crane operation, its effect is best.
Alarm can be how standby, but operating personnel must hold, and the other staff that do not have transmit alerting signal, and hoistman should civilization by predetermined operation, prevent crane inertia from pouring Keep Clear-High Voltage district.
