FIG. 1 is a perspective view showing an operation prevention blind of a power plant and a substation facility according to the present invention, and FIG. 2 is an exploded perspective view showing an important part of an operation prevention blind of a power plant and a substation facility according to the present invention.

FIGS. 3A and 3B are cross-sectional views showing the inside of a load pipe of the anti-tamper blind of the power plant and the substation equipment according to the present invention, FIG. 4 is a view showing the end cap of the anti-operation blind of the power plant and the substation equipment according to the present invention And FIG. 5 is a view showing a state in which an operation-preventing blind of a power plant and a substation facility according to the present invention is installed.

The operation-preventing blind of a power plant and a substation facility according to the present invention is installed at a power generation facility of a power plant or in front of a substation of a substation to prevent arbitrary operation of the power generation facility or substation facility. In other words, power generation facilities or substation facilities that require operations or repairs can be operated / repaired by raising the blinds, and the parts corresponding to power generation facilities or substation facilities that do not require operation or repair, .

The operation-preventing blind of the power plant and the substation equipment according to the present invention having the above functions includes a frame 100, a winding rod 200 installed inside the frame 100, A driving rod 400 for rotating the winding rod 200; a load pipe 500 connected to a lower end of the sheet 300; And a fixing strap (600).

The frame 100 is installed in front of the power generation facility or the power plant E. The power generation facilities of the power plant and the substation substation include various components made of steel such as valves, measuring instruments, operation levers, and switchboards containing them, and the frame 100 is installed in front of these components .

The winding rods (200) are rotatably mounted on the frame (100).

The sheet 300 is wound around the outer circumferential surface of the winding rod 200. The sheet 300 is configured to have a certain color and at the same time to have transparency of a certain degree, .

It is also possible to provide a warning to workers who work on the sheet 300 by printing warning notices or announcements of various phrases.

The driving rod 400 rotates the winding rod 200 in one direction or another direction so that the sheet 300 is wound or unwound on the winding rod 200.

The load pipe 500 is connected to a lower end of the seat 300, and functions to spread the seat 300 up. That is, the load pipe 500 minimizes the folding or bending of the sheet by pulling the sheet 300 downward, and is formed into a cylindrical shape having an empty space formed therein.

The load pipe 500 is formed with a central partition wall 510 crossing the inside thereof and a fitting hole 520 is formed horizontally on the upper side with respect to the central partition wall 510, And a sliding hole 530 is formed horizontally long on the lower side.

The central partitions 510 play an important role in keeping the load pipe 500 in a cylindrical shape. In other words, since the fitting hole 520 and the sliding hole 530 are formed across the right and left ends of the load pipe 500, the load pipe 500 is divided into two semicircular curved plates without the central partitions 510, Two semicircular curved plates are connected to the central partitions 510 so that the load pipe 500 can maintain a cylindrical shape.

The lower end of the seat 300 is inserted into the fitting hole 520. That is, when the lower end of the thick sheet 300 is pushed through the opposite ends of the load pipe 500, the sheet 300 is pushed and moved in the fit hole 520.

The sliding hole 530 is formed at a position facing the fitting hole 520. The fixing strap 600 is exposed through the sliding hole 530.

Meanwhile, the load pipe 500 includes a slider 540 slidable in the horizontal direction, and an end cap 550 is detachably installed on both ends of the load pipe 500.

The slider 540 moves freely in the horizontal direction (that is, the left-right direction) within the load pipe 500. Only one slider 540 may be provided inside the load pipe 500, but two sliders may be provided.

That is, the slider 540 may include a first slider 541 located on the left side of the load pipe 500 and a second slider 542 located on the right side of the load pipe 500.

The end cap 550 is installed at both ends of a load pipe 500 having both left and right ends opened to seal both ends of the load pipe 500. The end cap 550 prevents the sheet 300 from being released to the outside of the load pipe 500 and prevents the slider 540 from being released to the outside of the load pipe 500.

The end cap 550 is spirally coupled to both end surfaces of the load pipe 500. Thus, the length of the end cap 550 exposed in the load pipe 500 is adjusted.

The end cap 550 has a magnet 551 at its end.

The operation-preventing blinds of the power plant and the substation equipment according to the present invention may be installed only in front of the power generation facility, but in case of a large facility, a large number of the blinds may be arranged side by side. When a large number of such blinds are installed, each blind may be shaken by an external force such as wind, so it may be desirable to increase the resistance to external forces by connecting a plurality of blinds to each other. In order to connect the plurality of blinds to each other, in the present invention, the end cap 550 is configured to come out from the load pipe 500, and a magnet 551 is attached to the end of the end cap 550, So that it can be attached to the magnet 551 of the magnet 550.

In order to limit the movement of the first slider 541 and the second slider 542 installed in the load pipe 500, the first stopper 800 and the second stopper The stopper 900 is installed.

The first stopper 800 is installed on the right and left sides of the load pipe 500 so that the first slider 541 and the second slider 542 are slid toward the center of the load pipe 500 It blocks things.

That is, when a pair of first stoppers 800 are installed in the load pipe 500, the first slider 541 is connected to the first stopper 800 and the end of the load pipe 500 And the second slider 542 is positioned between the first stopper 800 and the end cap 550 coupled to the right end of the load pipe 500. Therefore, the distance between the first slider 541 and the second slider 542 can be adjusted by adjusting the distance between the first stopper 800 and the end cap 550.

The first stopper 800 may include a first block portion 810 slidable in the load pipe 500 and a second block portion 810 slidably coupled to the first block portion 810 to adjust the position of the first block portion 810 And a first fixing bolt 820 for fixing the first fixing bolt 820.

The first block 810 includes an upper block 811, a central portion 812 integrally formed at the lower end of the upper block 811 and a lower block 813 integrally formed at the lower end of the central portion 812. [ .

The center portion 812 passes through the sliding hole 530 of the load pipe 500.

The lower block 813 is located outside the load pipe 500 and contacts the outer surface of the load pipe 500 and has a width greater than that of the sliding hole 530.

The first block 810 does not drop downward by the upper block 811 to the lower side of the load pipe 500 while the lower block 813 is installed on the load pipe 500, 500).

The first fixing bolt 820 is screwed to the first stopper 800 while penetrating from the bottom to the top. When the first fixing bolt 820 is turned in one direction, the inner surface of the load pipe 500 is more detailed The upper end of the first fixing bolt 820 strongly urges the central partition wall 510 of the load pipe 500 to fix the position of the first block portion 810. Accordingly, the first stopper 800 blocks the first slider 541 and the second slider 542 from moving toward the center of the load pipe 500.

The second stoppers 900 are installed on the right and left sides of the load pipe 500 to prevent the first slider 541 and the second slider 542 from sliding toward the end cap 550 do.

That is, when a pair of second stoppers 900 are installed inside the load pipe 500, the first slider 541 and the second slider 542 are coupled to the first stopper 800, (900). The second stopper 900 is located closer to the end cap 550 than the first slider 541 or the second slider 542. Therefore, the distance between the first slider 541 and the second slider 542 can be adjusted by adjusting the distance between the first stopper 800 and the second stopper 900. If the first stopper 800 and the second stopper 900 are brought into close contact with both the left and right ends of the first slider 541 and the second slider 542, the first slider 541 and the second slider 542 are moved And is fixed in place.

The second stopper 900 may include a second block portion 910 slidable in the load pipe 500 and a second block portion 910 coupled to the second block portion 910, And a second fixing bolt 920 for fixing the fixing bolts.

The second block unit 910 includes an upper block 911, a central portion 912 integrally formed at the lower end of the upper block 911, and a lower block 913 integrally formed at the lower end of the central portion 912. [ .

The upper block 911 is inserted into the load pipe 500 and has a curved surface having a curvature similar to that of the inner surface of the load pipe 500 so as to smoothly slide in the load pipe 500. [ And the width of the sliding hole 530 is larger than that of the sliding hole 530.

The center portion 912 passes through the sliding hole 530 of the load pipe 500.

The lower block 913 is located outside the load pipe 500 and contacts the outer surface of the load pipe 500. The width of the lower block 913 is larger than that of the sliding hole 530.

The second block portion 910 does not fall down below the load pipe 500 by the upper block 911 while the second block portion 910 is installed on the load pipe 500, 500).

The second fixing bolt 920 is spirally coupled with the second stopper 900 while penetrating from the bottom to the top. When the second fixing bolt 920 is rotated in one direction, the inner surface of the load pipe 500 is more detailed The upper end of the second fixing bolt 920 strongly presses the central partition wall 510 of the load pipe 500 to fix the position of the second block portion 910. Therefore, the first slider 541 and the second slider 542 can not move toward the adjacent end cap 550 due to the blocking of the second stopper 900.

The upper end of the fixing strap 600 is fixed to the slider 540 and is exposed through the sliding hole 530. The lower end of the fixing strap 600 is connected to a fixing ring 700 attached to a power generation facility or a power-
