Abstract

PURPOSE:To easily set the position of a body and to make even fine position adjustments by providing a winding machine which is provided on a slide table and has a wound-up/down wire rope coupled at its terminal with the small- diameter side of a support rod. CONSTITUTION:The manual winding machine 10 which is operated with a handle 10a is fitted to the slide table 7, and the terminal of the wire rope 11 which is wound up and down by this winding machine is coupled with the small- diameter pipe at the lowermost end of the support rod 9. Further, an underwater telecamera 12 is fitted to the lower end of the support rod and the slide table 7 is operated to set the position of the underwater camera 12. Thus, the handle 10a of the winding machine 10 is rotated after the position is set roughly in both vertical and horizontal directions to expand and contract the support rod 9, positioning the underwater camera at a necessary position. Consequently, the body is easily positioned and also its position is adjusted finely.

Description

Detailed Description of the Invention [Technical Field of the Invention] The present invention relates to a position setting method that allows easy position setting of an underwater television camera, etc. used for inspecting fuel assemblies, for example, in a fuel storage pool of a nuclear power plant. Related to equipment.

[Technical background of the invention and its problems] In the fuel storage pool of a nuclear power plant, an underwater TV camera is used to monitor the status of fuel assemblies. In this case, it is necessary to position the viewing section of the camera near the subject.

1. As a position setting means for the door image part, conventionally, a pipe is connected to a river water pipe to form a support rod of the necessary length, the imaging part is fixed to the tip of this support rod, and the other end of the support rod is fixed. was lifted by a crane, etc., and workers operated the crane to set the position.

In the above conventional position setting means, to change the height direction position, the rod on which the pipes are joined is moved up and down, but if the vertical distance is large, the pipes are joined,
It is necessary to remove it. Furthermore, when the pipe is removed, it is also necessary to wipe off water adhering to the pipe. It is extremely troublesome to add and remove pipes and wipe off water as described above.

The support rod formed by connecting pipes was either hung by a crane or fixed to the poolside, so when changing the position of the underwater TV camera, the support rod would swing and the camera would not come to rest. The drawback was that fine position adjustment was not possible. The present invention has been made based on the above-mentioned circumstances, and an object of the present invention is to obtain a position setting device that can easily set the position of an object such as an underwater television camera and also allows fine position adjustment. .

[Summary of the Invention] The position setting device of the present invention includes a guide rod installed parallel to a pool wall surface, a substrate perpendicular to the guide rod that can be slid and positioned along the guide rod, and a substrate placed on the substrate. A slide base is provided and can be slid and positioned in a direction perpendicular to the guide rod, and the pipes are nested in order from a large diameter pipe to a small diameter pipe, and the large diameter end is rotatably positioned on the slide base. The present invention is characterized in that it has a support rod attached thereto, and a hoisting machine that is provided on the slide table and has an end of a wire lobe for hoisting and lowering the slide table connected to the small diameter end of the support rod.

[Embodiment of the Invention] FIG. 1 is a front view of an embodiment of the present invention, and FIG. 2 is a side view thereof.

The position setting tool of the present invention is attached to a guide rod 1 which is installed near the pool almost parallel to the pool wall surface (a vertical plate 5 is attached via an attachment part 4 so as to be rotatable about the eye movement localization 3). and a board 6 attached vertically to the upper end of this vertical plate 5.
and a horizontal slide stand 7 attached to the tip of this board 6.

The slide table 7 rotatably supports the large-diameter end of a support 9, which is made up of pipes 8 of appropriate lengths, ranging from large to small diameter, assembled in a nested manner.

The pipes 8 are connected to each other by a key and a keyway, for example, so that they can move in the axial direction (although they can move, but are restrained in the circumferential direction).In addition, the slide base 7 has a manual winding that is operated by a handle 10a. An upper machine 10 is attached, and a wire rope 11 is hoisted and lowered by this hoist.
The end of the support member 9 is connected to a small diameter pipe at the lowermost end of the support member 9. Further, an underwater television camera 12 is attached to the lower end of the support rod.

In the figure, 13 is a tightening screw for fixing the support body 2 to the guide rod 1, 14 is a tightening screw for fixing the mounting part 4 to the shaft 3, and 15 is a screw for sliding the pipe at the top end of the support rod 9. A tightening screw 16 for fixing to the table 7 is used for a slide table lock. First, loosen the tightening screw 13,
The support body 2 is moved along the guide rod 1 to set the approximate position. At this point, the tightening screw 13 is tightened to fix the support body 2. This means that the rough position setting in the vertical direction has been completed, but the position setting in the lateral direction can be done by any of the following methods. That is, when the amount of lateral movement vl is relatively small, the tightening screw 14 is loosened and the mounting portion is made to take a picture of the neck around the shaft 3, so that the underwater television camera 12 approaches the required position. Now tighten the tightening screw 14 and fix the mounting part to the shaft 3.
Fixed to.

If the amount of movement in the lateral direction is large, loosen the slide block locking screw 16 and operate the slide block 7. After completing the rough position setting in the vertical and horizontal directions in this way, turn the handle 10a of the hoisting machine 10. The support body 9 is expanded and contracted to position the underwater television camera at a desired position.

Next, to change the direction of the underwater television camera, loosen the hoof screw 15 and rotate the support rod 9.

As described above, according to the device of the present invention, it is possible to finely adjust and set the underwater television camera not only vertically and horizontally, but also its direction.

[Effects of the Invention] According to the present invention, the position, orientation, and setting of objects such as underwater television cameras can be finely and easily adjusted without requiring troublesome steps such as adding and removing pipes. Therefore, for example, the workability of monitoring fuel assemblies in a fuel storage pool of a nuclear power plant can be significantly improved.
