Background technology
Through retrieval Patent documents of interest, not yet retrieve a kind of preventing damage to power transmission line caused by external force device identical with the utility model structure at present.Along with urban construction scale constantly expands, all kinds of constructions near ultra-high-tension power transmission line get more and more, when the Overheight Vehicles such as construction hoist enter and to carry out operation near ultra-high-tension power transmission line, too small with the spacing of ultra-high-tension power transmission line, easy formation flashover fault, jeopardize life safety and the large-area power-cuts of operating personnel, traditional artificial line walking mode inefficiency, and be that the anti-outside destroy system of main flow does not reach prevention in time and the on-the-spot effect prevented with Video Supervision Technique, estimate by floor manager personnel, because standing, which angle is different, range estimation estimated distance differs larger with actual range, the generation very easily caused the accident, so be necessary to design a kind of preventing damage to power transmission line caused by external force device, reduce the economic loss caused because of outside destroy circuit.
Summary of the invention
The purpose of this utility model to provide a kind of efficient, stable, and have range finding accurately, effectively containment transmission line of electricity suffers a kind of preventing damage to power transmission line caused by external force device of outside destroy.
Technical characteristic of the present utility model is: easy for installation in consideration, the reliable basis of usability is designed to a kind of preventing damage to power transmission line caused by external force device be made up of electric field intensity measuremenrt module, ultrasonic distance measuring module, multifunctional controller, range display, phonetic alarm, light crossing-signal, power-off protection controller, electric field intensity measuremenrt module, ultrasonic distance measuring module to be separately positioned on construction machinery and to be connected with multifunctional controller input end; Range display, phonetic alarm, light crossing-signal, power-off protection controller are connected with multifunctional controller output terminal respectively; Described power-off protection controller is connected with construction machinery general supply input end.
Described electric field intensity measuremenrt module is calculated device formed by power-frequency electric field strength sensing device, enlarge leadingly device, filtering conditioning device, electric field intensity, and power-frequency electric field strength sensing device output terminal is connected with enlarge leadingly device input end; Enlarge leadingly device output terminal and filtering are nursed one's health device input and are connected; Filtering conditioning device output end calculates device input with electric field intensity and is connected; The magnetic field intensity information induced is sent to a kind of device of enlarge leadingly device by described power-frequency electric field strength sensing device.
Described ultrasonic distance measuring module by distance exam transceiving device, driving circuit, selector, emitting head, accepting header, accept converter, signal accepts processor and forms, distance exam transceiving device accepts processor with driving circuit signal respectively and is connected; Selector is connected with driving circuit, emitting head respectively; Accept that converter accepts processor with signal respectively, accepting header is connected.
During use, power-off protection controller is connected with construction machinery general supply input end, electric field intensity measuremenrt module, ultrasonic distance measuring module are arranged on the motion arm of construction machinery, electric field intensity measuremenrt module is measured line electricity magnetic field, utilizes the magnetic field intensity measured to calculate the distance between alive circuit and construction machinery motion arm, utilize ultrasonic distance measuring module, by hyperacoustic transmitting and acceptance, realize the measurement of circuit distance under power down mode, the distance value measured is shown on range display simultaneously, when the safe distance that the distance measured sets close to it time, phonetic alarm device will send voice warning sound, light warning device sends highlighted warning light, construction machinery operating personnel are reminded to take care, when the data measured are less than the safe distance of setting time, power-off protection controller will cut off the general supply of construction machinery, make preparation of construction out of service, thus guarantee the safety of transmission line of electricity.
The utility model has the advantages that: owing to being provided with electric field intensity measuremenrt module, thus calculate the distance between construction machinery and transmission line of electricity more accurately according to electric field intensity; Owing to being provided with ultrasonic distance measuring module, thus at transmission line of electricity without the distance also can measured when electricity between preparation of construction and transmission line of electricity; Owing to being provided with electric field intensity measuremenrt module simultaneously, ultrasonic distance measuring module carries out two mirror induction measuring and calculating, thus makes range finding more accurate; Due to rational in infrastructure, use, easy to operate, so there is very large practical and popularizing value.
