Abstract

Insulators fitted to pylons carrying electric power lines are cleaned by spraying them from a helicopter. The helicopter 1 has a pivotted boom 2 made of pressure hose (7, figures 4, 5 & 6) covered with foamed polystyrene (8) and epoxy carbon (10) to make it light but rigid. The nozzle (11) at the end of the boom may be moved by an operator in the helicopter. The water tank 3 and pump 4 act as a counter weight to the boom 2. <IMAGE>

Description

The present invention relates to an airborne spraying and washing device and more particularly to a spraying and washing device installed on a helicopter adapted to perform special assignments such as - but not exclusively - cleaning and washing of electric insulators fitted to pylons carrying H.T. and L.T. power lines.
It is known to use helicopters for many civilian assignments, such as agriculture, field spraying or fire extinguishing assignments, In order to perform any of the many assignments, the helicopter is equipped with specially designed equipment, It is known to attach to the front part of a helicopter a spraying boom so as to perform a variety of jobs, however it has been found that due to the construction of the helicopter, it requires a very long boom, Experience has also shown that having such a boom at the front of the craft is hazardous and inconvenient for performing several jobs which require proximity to the object.
Electric insulators require periodic "washing" to remove the 6lution therefrom. Such cleaning was performed by a water tanker equipped with a high pressure pump which travels on the ground along the power lines and cleans the insulator with a water jet emersing therefrom. It is quite apparent that such a system would face many difficulties such as the need to climb up the pylons in order to reach the insulator, or the fact that there are pylons installed off road where access is difficult, On the whole, such cleaning is a time consuming operations more so, for obvious safety reasons, the power is to be switched off.
It has thus been proposed to clean and wash the insulators from the air by means of a sprayer attached to a helicopter to overcome all deficiences.
It is thus the primary object of the present invention to provide a spraying and washing assembly which will overcome the above deficiencies.
It is a further object of the present invention to provide an adjustable spraying boom of considerable length capable of performing all spraying jobs.
The invention will now be described with reference to the annexed drawings, in which: Fig. 1 is a frontal illustration of a helicopter equipped with the spraying boom.
Fig. 2 is a partial side view of the helicopter, Fig. 3 is a top view of the helicopter.
Fig. 4 is a cross section of the boom, Figs. 5 and 6 are enlarged illustrations of the spraying end of the boom.
As can be seen in the illustration, the helicopter 1 is equipped with a boom 2 which has a considerable length. In order to be able to fly and perform its function, said boom 2 is of light weight construction as will be referred to. At any rate, the weight of the boom is compensated by the water tank 3 and pump 4 which act as counter weight to said boom. The operator OP is placed in a position (Fig. 3) which enables him to view the boom and aim it very accurately towards the insulator, Boom 2 is pivotably mounted at 5 on support 6 which in turn is attached to the helicopter, Boom 2 comprises a pressure hose 7 placed within a cover 8 made of foamed polystyrene covered with a layer of epoxy carbon 10, a construction which gives the boom rigidity on the one hand and light weight on the other. The free end of boom 2 is provided-with nozzle 11 pivotably connected to boom 2 at 12 which enables "up" or "down" movement by means of cable 13, the far end connected to handle 14 and spring 15. Such movement enables the operator OP to reach all parts of the insulator, The boom 2 is further equipped with two "handles" 16 which enable the operator to manipulate the boom,
