DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pot-type aerial remote control station used for power distribution equipment.

[0002]

2. Description of the Related Art As shown in FIG. 2 (C), a cover 11 is provided on a bottom surface 1 'of a case of a conventional distance control device 1, a hinge 9 for opening and closing the cover 11 at one end of the cover, and other components. The end is provided with a fastening fitting 10 for fastening when the lid 11 is closed and fixing the lid 11 in the closed state, and is configured to house a power switch (not shown) and a setting connector. A packing is provided on the inside of the lid 11 so that rainwater or the like does not easily enter when the lid is closed.

In use, a telecontrol device 1 and a section switch for separating a distribution line into sections are installed on a utility pole, and a control cable from the section switch is connected to a control connector 4 of the telecontrol device 1. The power cable from the power transformer is connected to the power connector 3, and the communication cable for communication control is connected to the communication cable grant 14. Reference numeral 5 denotes a power receiving lamp, and 6 denotes a control output lamp.

When the remote control 1 is operated, first the fastener 10 is loosened, the lid 11 is opened, and the power switch is turned on.
Then, a setting device (not shown) is connected to the setting connector to perform setting. Next, the setting state is confirmed by the manual operation handle 7 or the remote control, a facing test such as a switch control operation, and a switchback operation are performed. After confirming that there is no abnormality, the lid 11 is closed and the fastening fitting 10 is closed. And complete operation.

[0005]

However, this prior art has the following problems. (1) Due to the structure in which only one side is tightened using a hinge, there is a possibility that water may enter even when the lid is closed, for example, when the weather is strong. Therefore, it is necessary to adopt a waterproof structure part for the power switch and the connector housed in the lid. (2) When closing the lid that is open around the hinge, the lid must be closed and fixed with a clamp. One-handed work is difficult and requires both hands. However, the opening operation is often a pole-up operation, so using both hands is dangerous. Therefore, an object of the present invention is to provide a remote control device that has a simple structure and that can reliably ensure waterproofness.

[0006]

SUMMARY OF THE INVENTION In order to solve this problem, the present invention provides a circular pipe with a tap on the bottom of a pot-shaped case of a remote control, and a screw for the circular pipe connected to the bottom with a chain. A watertight cap provided with a thread groove to be screwed with the groove is provided so that at least the power switch and the setting connector are housed in such a manner that the circular pipe surrounds and accommodates the power switch and the setting connector. Waterproofing has been ensured so that one-handed work is also possible. An O-ring is provided on the waterproof cap to improve waterproofness.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG. FIG. 1 shows the configuration of the device of the present invention, and the same parts as those of the conventional device are denoted by the same reference numerals. As shown in the figure, the remote control device 1 has a power switch 12 and a setting connector 1 that are used only during operation, inspection, or failure.
3 and so on. When not in use, do not touch them easily. Also, to prevent rainwater from entering, a protective cap 2
Is provided. In this embodiment, the power switch 12 and the setting connector 13 are arranged on the bottom surface 1 'of the case inside the tapped pipe 15 provided with a thread groove on the outside, and the screw groove is formed on the inside of the outer edge surrounding the pipe 15. The applied waterproof cap 2 is connected to the bottom surface 1 ′ of the case by a chain 8.

At the time of work, the cap 2 is turned with one hand to remove it, the power switch 12 is operated, and a setting device (not shown) is connected to the setting connector 13 for work. At this time, the waterproof cap 2 is suspended from the case bottom surface 1 'by the chain 8. When the operation is completed, the setting device is removed, and the waterproof cap 2 suspended by the chain is fastened to the pipe 15 with one hand to bring it into a normal operation state. If the chain 8 and the waterproof cap 2 are connected so as to rotate freely, the chain will not be wrapped when the cap 2 is fastened to the pipe 15, so that the operation is not difficult.

In this embodiment, a screw groove is formed on the outside of the pipe 15 and a screw groove is formed on the inside of the outer edge of the cap 2 surrounding the pipe 15 so as to cover the pipe 15 with the cap 2. The cap 2 may be fitted into the pipe 15 by providing a thread on the outside of the circular convex portion of the cap 2 that fits into the pipe 15. In this embodiment, only the power switch 12 and the setting connector 13 are described as being arranged inside.
Parts required only for inspection and operation such as display lamps can be arranged. Further, the shape of the waterproof cap is not limited to a circular shape, but may be any shape as long as it is screwed with the pipe.

[0010]

According to the present invention, (1) by using a waterproof cap with an O-ring, a highly reliable waterproof performance can be obtained with a simple structure. (2) In addition, since reliable waterproofing is obtained, low-cost switches and connector parts used without waterproofing can be employed. (3)
Work with one hand is facilitated, and workability and safety when climbing the pole are improved.
