Abstract

PURPOSE:To remove the ice and/or snow adhering to an overhead power- transmission line. CONSTITUTION:A hot water device 9 for raising water temperature is mounted on a self-traveling dolly 1 which moves on a powertransmission line 6 and the hot water from the device 9 is led to a sprinkling device 12 through a pump 10 and sprinkled on the line 6. The sprinkled hot water and the water produced from melted ice and/or snow are circulated to the device 9 after they are recovered by means of a water retaining device 13. In addition, the ice and/or snow which cannot be removed by the sprinkled hot water is removed by a rotating brush 14 rotated by means of a rotating device 11.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power transmission line ice and snow removal device for removing ice or snow deposited on power transmission lines.

0002

[Prior Art] In the past, there was a similar device as shown in Figure 4 shown in pages 41 to 44 of the October 1988 issue of Electrical Field Technology, but this device was designed for the purpose of inspecting power transmission lines. However, it was not intended to remove ice or snow that had adhered to power transmission lines. In the figure, 1 is a self-propelled trolley, 2 is a television camera, 3 is a VTR, 4 is a lighting device, 5 is a power supply device, 6 is a power transmission line, and 7 is a drive motor. Also, in the product information catalog of Fujikura Electric Wire Co., Ltd., the L shown in Figure 5
The C-spiral method is introduced. In the figure, 6 is a power transmission line, and 8 is a low Curie wire coated with aluminum or copper.

Next, the inspection device shown in FIG. 4 will be explained. A self-propelled trolley 1 installed on a power transmission line 6 is moved by rotating wheels using a drive motor 7. A power supply device 5 mounted on the trolley 1 supplies the power necessary for the self-propelled trolley 1 to travel and the power to the mounted equipment. In order to photograph the situation of the power transmission line 6, the trolley 1 is equipped with
A television camera 2, a lighting device 4, and a VTR 3 are provided. Inspection of the power transmission line 6 is performed visually by playing back the tape recorded on the VTR 3 on the ground (in an office, etc.).

Next, the LC spiral winding method shown in FIG. 5 will be explained. A low Curie (LC) wire 8 coated with aluminum or copper is wound around the power transmission line 6, and the heat generated by the magnetic field is used to melt snow.

[Problems to be Solved by the Invention] The conventional device is a device for carrying out inspections as described above, and does not take into account the removal of ice or snow. In addition, the method of wrapping a separate wire around the power transmission line required a huge amount of work (cost) to add to existing equipment, and there were other problems, such as the dangerous work required riding in a gondola.

[0006] This invention was made in order to solve the above-mentioned problems, and it prevents damage to power transmission lines due to ice or snow adhesion, covers a wide area with one device, and reduces total cost. The purpose is to achieve this goal.

[0007]

[Means for Solving the Problems] An apparatus for removing ice and snow from a power transmission line according to the present invention heats water and sprinkles water from the upper part of the power transmission line to melt ice and snow, and at the same time, the hot water and melted water sprinkled at the lower part of the power transmission line are heated. The water is collected in a water retainer and circulated to the water heater.

[0008]

[Operation] In the power transmission line ice and snow removal device according to the present invention,
Hot water heated by a water heater is used to melt and remove ice or snow adhering to power transmission lines.

[0009]

[Example] Example 1. An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 denotes a self-propelled traveling trolley that moves under its own power after being installed on a power transmission line 6, 5 a power supply device that supplies the power necessary for driving and mounting equipment of the self-propelled traveling trolley 1, and 6 1 is a power transmission line, 7 is a drive motor for driving the self-propelled trolley 1, 9 is a heater heating type water hot water device,
10 is a pump that sends hot water heated by the water heater 9 to the water sprinkler 12; 11 is a rotating device composed of a motor and gears for rotating the brush 14; 12 is a water sprinkler that sprays hot water onto the power transmission line 6; 13 14 is a water retainer that receives warm water sprinkled from the water sprinkler 12 and melted ice or snow;
is a brush rotated by a rotating device 11 in order to remove ice or snow adhering to the power transmission line 6.

Next, the operation of the present invention will be explained. The self-propelled trolley 1 is installed on the power transmission line 6 using a lifting method using a steel tower, as in the past. Water is injected into a hot water device 9 provided in the self-propelled traveling trolley 1, and when the power supply device 5 is turned on, the heater in the hot water device 9 heats up, raising the water temperature. A pump 10 provided at the outlet of the water heating device 9 in conjunction with the start command of the self-propelled traveling trolley 1
operates and sends hot water in the water heater 9 to the water sprinkler 12. The water sprinkling device 12 has a pipe shape and is provided with water sprinkling holes (dotted circles shown in FIG. 2), so that hot water falls onto the power transmission line 6. The self-propelled trolley 1 moves while melting ice or snow adhering to the power transmission line 6 with this hot water. Sprinkled hot water and water melted from ice or snow adhering to the power transmission line 6 are collected in a water retainer 13 and circulated to the water heating device 9. In addition, remaining ice or snow that cannot be completely melted by simply applying hot water is removed by installing a brush 14 that is rotated by a rotating device 11 provided at the rear so as to sandwich the power transmission line 6. .

Although the above embodiment has been described as a device for removing ice or snow adhering to power transmission lines, it may be combined with the inspection device introduced in the prior art, or the installed device may be made into a unit and used as a replaceable device. You may do so. Alternatively, the present invention may be used for purposes such as removing salt from power transmission lines by using water or chemicals without using hot water.

0012

[Effects of the Invention] As described above, according to the present invention, a self-propelled traveling trolley is used and there is no need to replenish the water necessary to melt ice or snow, so a wide area can be covered with one vehicle. Total cost can be reduced. Also,
Since ice or snow is removed by turning it into water, safety can be improved without worrying about accidents occurring when the device falls on power lines near residential areas.
