Abstract
The invention relates to a novel process for cleaning ice or snow covering a transmission line and a laser de-icing machine. In the process, a high-power laser is adopted to lead the laser to irradiate an iron tower and a cable, the intense laser radiation heating is used to lead part of the ice and snow covering connection transmission line to be molten, and the rest of ice and snow fall onto the ground. The laser de-icing machine consists of a power generator, a laser, a reflective mirror, a high-power collimation mirror and a fine regulating device which links the reflective mirror and the collimation mirror, wherein the power generator is connected with the laser through a cable; the laser and a transmitting frame are arranged on a base; an angle regulating device is fixed on the transmitting frame; and the angle regulating device can regulate the collimation mirror and the reflective mirror through linkage. The novel process has the advantages of high speed for cleaning the ice and snow covering the high-voltage transmission line, labor-saving performance and good security.
Description
Technical field
The present invention relates to the high-voltage fence maintenance of way technical field, particularly winter and remove the new technology and the laser deicing machine of powerline ice-covering, snowberg.
Background technology
The most of area of China sleet is in the winter time come temporarily, and removing powerline ice-covering, snowberg are the common problems of the high-voltage fence maintenance of way.For example: in January, 2008,50 years sleet and heavy snow weather of not meeting appear in the Yangtze river basin, and icing on many transmission line cables, the pylon, snowberg are serious, and swing has significantly appearred in a lot of circuits, and is precarious.Morning January 17, national grid is positioned at innerland, Da Bie Mountain area ± 500 kilovolt suitable magnificent DC power transmission line #1146-#1153 strain insulator part of path, collapse, cause large-area power-cuts, lose huge because of the heavy burden that can't bear ice and snow causes transmission line and 4 iron towers to be badly damaged.
Existing removing ultra-high-tension power transmission line icing, snowberg work are to climb iron tower by the people substantially, knock icing, snowberg, make it to shake the face that lands.Its inefficiency, and the personal safety accident very easily takes place.
Summary of the invention
The purpose of this invention is to provide a kind of removing powerline ice-covering, snowberg new technology and laser deicing machine, this process using high power laser makes laser radiation iron tower, cable, utilizes the intense laser radiation heating, make icing, snowberg connect the transmission line partial melting, all the other ice and snow ground of dropping.This technology is removed the ultra-high-tension power transmission line icing, snowberg speed is fast, saves manpower, and fail safe is good.
In order to address the above problem, the present invention realizes by the following technical solutions:
Laser is removed powerline ice-covering, snowberg new technology, it is characterized in that: this technology is that the mode of employing laser emission heating is removed icing, the snowberg on the transmission line.
Described laser is removed the laser deicing machine of powerline ice-covering, the employing of snowberg new technology, it is characterized in that this device by generator, laser, reflective mirror, high power gun sight, the micromatic setting of reflective mirror and gun sight interlock is formed, generator links to each other with laser by cable, laser and launcher are installed on the base, angular adjustment apparatus is fixed on the launcher, and angular adjustment apparatus is the device that linkage is adjusted gun sight and speculum.
Compared with prior art, the invention has the beneficial effects as follows:
1, utilize laser to remove ultra-high-tension power transmission line icing, snowberg new technology, operating speed is fast, and the quality height can effectively be protected the safe operation of national grid.
2, laser deicing is people and the untouchable operation of ice and snow (ultra-high-tension power transmission line), has improved safety factor of workers greatly, has improved personnel's operating condition.
3, laser deicing need not cut off the power supply and can carry out operation, and find at any time to remove at any time, can remove ultra-high-tension power transmission line icing, snowberg not influencing under the situation that ultra-high-tension power transmission line transmits electric power, ensure the continuous operation of ultra-high-tension power transmission line, reduce the economic loss that ultra-high-tension power transmission line is stopped transport and caused

Embodiment
Narrate preferred forms of the present invention below by embodiment.
See Fig. 2, the laser deicing machine by generator 1, cable 2, high power laser 3, launcher 4, high power gun sight 5, speculum 6, base 8, the angular adjustment apparatus 7 of speculum 6 and high power gun sight 5 interlocks is formed.Generator 1 links to each other with laser 3 by cable 2, and laser 3 and launcher 4 are installed on the base 8, and angular adjustment apparatus 7 is fixed on the launcher 4.Angular adjustment apparatus 7 linkages are adjusted gun sight 5 and speculum 6, and adjusting angle is horizontal direction 360 degree, and vertical direction 0 is spent to 90 degree.To laser 3 power supplies, the laser beam that laser 3 produces makes laser beam 9 shine assigned address through speculum 6 reflections by high power gun sight 5 and angular adjustment apparatus 7 to generator 1 by cable 2.
Laser is removed powerline ice-covering, snowberg new technology process is:
Should reconnoitre operating location in advance during operation, beyond 100 meters in the cable both sides of adjacent two iron towers, each selects one to two energy intervisibility circuit and saturating empty preparation operating location.When powerline ice-covering, when snowberg occurs, vehicle-mounted laser deicing machine start preheating, the LASER HEATING point that the operator aims on the ultra-high-tension power transmission lines speculum 6 of high power gun sight 5 and interlock with it by work angle adjusting device 7, after opening laser 3, laser beam 9 shines LASER HEATING point (cable or iron tower steel construction) heating through speculum 6, utilize the good characteristics of metal fever conductibility, icing (or snowberg) thawing in the hot spot zone is made it to come off.After the operator sees that in high power gun sight 5 icing (or snowberg) of LASER HEATING point drops, by angular adjustment apparatus 7 adjust laser beams left (right side) move, continue to remove icing, snowberg on the transmission line.After the icing (or snowberg) on adjacent two iron towers and the cable drops ground substantially, close the laser deicing machine, be transferred to next setting operation.
For guaranteeing safety, the present invention adopts following safety measure:
(1) the laser emitted laser wavelength of selecting for use should be avoided the easy wave band that human eye is damaged;
(2) answer the site clearing before the operation, in order to avoid the ice that falls is hurted sb.'s feelings;
(3) before the fine operation, should get in touch with blank pipe department;
(4) by control, guarantee that illuminated some temperature of cable is no more than 200 ℃ to laser power and illuminated laser spot spot size.
