FIELD OF THE INVENTION
This invention relates to a device which, by means of wind,
cleans insulators used in electrical systems.
BACKGROUND OF THE INVENTION
As dust and dirt gather easily on the surfaces of insulators
used in electrical systems, they have to be cleaned periodically. In general, this
involves manual or automatic cleaning, both of which are time and labour-consuming.
Devices for that purpose are known from the documents
US-A-3 532 804
,
JP-A- 8 185 743
and
CN2368137Y
. Washing insulators with electrostatic fluid is also possible, but the
costs incurred can be high. Moreover, it is not always possible to use machines
or electrostatic fluid to perform the cleaning work due to constraints of space
or location. Notwithstanding the method of cleaning used, insulators have to be
cleaned in time to prevent dirt causing sparking in electrical systems.
SUMMARY OF THE INVENTION
In view of the above, this invention is aimed at overcoming
the shortcomings in the present state of technology by providing wind-driven cleaning
rings to remove automatically dirt accumulated on insulators.
With this purpose in mind, the inventor adopted the following
method to construct the cleaning rings. Each cleaning ring is inserted into a series
of bowls arranged in the same direction so that it is driven by wind. The ring is
then installed on the insulator continuously. When turned by wind, the bowls on
the cleaning ring scrape off the dirt on the surface of the insulator. Sparking
through dirt can therefore be prevented as the surface of the insulator is kept
clean at all times.
The advantages of this invention, when compared with prior-art
systems, are as follows:
- 1. Cleaning is continuous and insulator surfaces are kept clean at all times.
- 2. Large amount of labour and resources is saved.
- 3. The risk factors brought about by cleaning using traditional methods are
eliminated.

DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION
Figs. 1 to 7 show the structure of embodiment 1 of this
invention. Fig. 1 is a plan view and a left cutaway view of a wind-driven bowl (1)
in the shape of a hemispheroid, which can also be a paraboloid. Fig. 2 is a plan
view and a left cutaway view of a wind-driven bowl (1) in the shape of a cylindrical
cone, which can also be of other forms of taper. Figs. 3 and 4 show a partial cutaway
view of a wind-driven bowl (1) with an insulating ring (3) running through its aperture
(2). It can be seen here that the bowl is adhered and fixed onto the insulating
ring. Fig. 5 shows an insulating ring (3) inserted into with a series of wind-driven
bowls (1) arranged in the same direction to form the structure of the cleaning ring.
Fig. 6 is a schematic diagram of an insulator (4). Fig. 7 shows an insulator (4)
fitted with a wind-driven cleaning ring. When blown by wind, the ring revolves and
the edges of the bowls scrape off the dirt on the surface of the insulator (4) continuously.
This maintains the cleanliness of the insulator at all times and prevents the occurrence
of sparking through dirt. The wind-driven rings are made of insulating materials
such as plastic, rubber or nylon. They can be installed on the insulating porcelain
skirts of any component in an electrical system.
Figs. 8 and 9 show embodiment 2 of this invention. The
difference between embodiment 2 and embodiment 1 lies in the incorporation of a
scraping edge (5) on the wind-driven bowls (1), by which cleaning is better facilitated.
Figs. 10, 11 and 12 depict embodiment 3 of this invention.
It can be seen from the diagrams that separating beads (6) punctured through the
centre are fitted between the wind-driven bowls (1) onto the insulating ring (3).
These beads are used to maintain the distance between the bowls (1), and can be
in the shape of a ball or a tube. Fig. 12 is a partial cutaway view of an insulating
ring (3) inserted into a pair of bowls separated by tubular beads (6).
Fig. 13 shows embodiment 4 of this invention. It can be
seen from the diagram that convex rings (7) are fitted onto the insulating ring
(3) to keep the wind-driven bowls (1) in position.
Figs. 14 and 15 show embodiment 5 of this invention. Brush
rings through which the insulating ring is located are used to improve the efficiency
and effectiveness of the cleaning process. Fig. 15 shows a cutaway view and a side
elevation view of a brush ring (8).
Figs. 16 and 17 show embodiment 6 of this invention. Scraping
boards (9) through which the insulating ring (3) is located are used to scrape clean
the porcelain skirt. Fig. 17 is a plan view and a side elevation view of a scraping
board (9).
Figs. 18 and 19 show embodiment 7 of this invention. The
wind-driven bowls (1) and the insulating ring (3) are integral to each other; they
are manufactured as part and parcel of the same cleaning ring in one go, yielding
a one-piece fabrication.
Figs. 20 and 21 show embodiment 8 of this invention. As
illustrated in the diagrams all wind-driven cleaning rings are beset by the problem
of connection. The joints (10) can be welded together, or soldered or adhered together
by using a connecting tube (11), as depicted in Fig. 21.
Fig. 22 shows embodiment 9 of this invention. It is different
from the previously mentioned embodiments in the way the wind-driven bowls (1) are
fitted on the insulating ring (3). Here the bowls are not inserted into the ring
through its centre, but are fixed onto its side.
INDUSTRIAL APPLICATIONS
This invention can be widely used in different electrical
systems to remove dirt accumulated on the surfaces of insulators, thereby improving
safety in the operation of the systems. The advantages this invention has over prior-art
systems are as follows: 1. Cleaning is continuous and insulator surfaces are kept
clean at all times; 2. Large amount of labour and resources is saved; 3. The risk
factors brought about by cleaning using traditional methods are eliminated.
