Description
Technical Field
The utility model relates to a helicopter paddle defroster.
Background
Helicopters have been introduced and are used in more and more applications in civilian areas, and the service of helicopters is highly effective. In the land development work, the ground transportation means are difficult to reach and the ground transportation means are used in complicated terrain areas or remote areas, and the helicopter is used, so that the bridge building and the railway building are not needed to be opened, and the time and the cost can be greatly saved. The blades of the helicopter are not only lift components, but also have the main functions of operation and the like, and the pneumatic, balance and dynamic characteristics of the blades are changed in many areas due to icing and frosting of the blades, so that the flight safety of the helicopter is endangered. In order to ensure the flight safety of the helicopter under frosting environmental conditions, protective measures must be taken for the helicopter.
Disclosure of Invention
The utility model aims at providing a helicopter paddle defroster.
The above purpose is realized by the following technical scheme:
a helicopter blade defroster comprising: bottom plate and riser, the both ends of bottom plate respectively with two the riser be connected perpendicularly, two the riser between the lower part install two bottoms that the structure is the same scrape the board frame, two the riser between the top install two tops that the structure is the same and scrape the board frame, just the top scrape the board frame with the bottom scrape the board frame pass through the bolt with riser fixed connection, two the top scrape the board frame with two the bottom scrape and be parallel structure, two the top scrape board frame and two the bottom scrape the board frame on same horizontal plane, the below intermediate position of bottom parallel be fixed with two otic placodes, and two the otic placode between be connected with the telescopic link through bolt assembly.
Helicopter paddle defroster, the intermediate position of riser seted up the jack both ends seted up the balancing pole jack, the jack in insert and have the inserted bar, the balancing pole jack in insert the balancing pole, the one end and the spacing fixed connection of U type of inserted bar, the other end and limiting plate fixed connection, the limiting plate with the spacing of U type between be provided with the spring, just the spring housing the face of inserted bar on.
Helicopter paddle defroster, two spacing of U type between insert the paddle, the top scraper blade with the bottom scraper blade on be fixed with the defrosting offset plate through bolt assembly, the top scrape the board frame with the bottom scrape the board frame and be U type structure.
The utility model discloses the beneficial effect who reaches is:
1. the utility model has simple structure and convenient operation, is mainly suitable for a small civil aircraft with the height below 3 tons, the aircraft height is 3.19 meters, the aircraft length is less than 11.97 meters, and the diameter of a rotor wing is 10.5 meters, when frost appears on the blade of the helicopter, firstly, the telescopic rod is fixed between the two ear plates through the bolt component, so that the ear plates and the diameter of the telescopic rod form a certain angle, the device is convenient to slide on the blade, then, two U-shaped limiting frames on the device are respectively sent from the end parts of the blade, so that the two ends of the blade are attached to the U-shaped frames, then the telescopic rod is dragged, the telescopic rod drives the defrosting device to move on the blade through the ear plates, at the moment, the top and the bottom of the blade are respectively contacted with the defrosting rubber plate on the top scraping plate frame and the defrosting rubber plate on the bottom scraping plate frame, the frost of the blade is removed through the defrosting rubber, time and labor are saved.
2. The utility model discloses one end at the spacing frame of U type is provided with the pole, the inserted bar passes the jack on the riser, and embolia the spring on the inserted bar, because the width of paddle is changing, the paddle width broad of middle paddle and tip, consequently through promoting the spacing frame of U type, the spacing frame of U type can change the distance between two spacing frames of U type through the elasticity of spring, thereby can make vertical face on two spacing frames of U type contact with the both ends of paddle all the time, thereby play limiting displacement, and set up the stability that the spacing frame of U type can be guaranteed to the balancing pole, prevent that the spacing frame of U type from taking place to rock.
3. The utility model discloses scrape the board frame at the top of riser is provided with two tops, scrape the board frame in the bottom is provided with two bottoms, and scrape board frame and two bottom scraper blade shelf location defrosting offset plates at the top respectively through a set of bolt assembly, it has two to scrape the board frame structure to adopt every layer, can make the defrosting offset plate on the first of top or below scrape the board frame after the frost of paddle is got rid of, the defrosting offset plate on the second of rethread top and bottom scrapes the board frame carries out the second defrosting, carry out both sides and get rid of the frost, it is more thorough to get rid of the effect.
