[0028] In order to make the content of the present utility model more clearly understood, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model

[0029] AsFigures 1 to 7 As shown in the figure, a warning sign for substation maintenance includes a column 1. There are two columns 1, and the lower ends of the two columns 1 are fixedly installed with bottom columns 2. The lower ends of the bottom columns 2 are installed with ground plugs for convenient contact with the ground for fixation. Grooves 4 are opened at one end where the two columns 1 are close to each other. Jacks 3 are opened on the upper surface of the bottom column 2, and the jacks 3 are located inside the grooves 4. A warning board 6 is located between the two columns 1. The surface of the warning sign 6 has a sign of "Maintenance, No Entry" to warn unauthorized personnel to stay away. A slidable connecting plate 7 is installed inside the warning board 6. The distance between the two columns 1 is determined by the total length of the warning board 6 and the two connecting plates 7. An extension structure 9 is installed inside the warning board 6 to adjust the distance between the two connecting plates 7.

[0030] The extension structure 9 includes a screw rod 18. The screw rod 18 is vertically and rotatably installed inside the warning board 6. A turntable 19 is installed at the lower end of the screw rod 18. Rotating the turntable 19 can drive the screw rod 18 to rotate. A moving plate 20 is sleeved on the surface of the screw rod 18. The moving plate 20 is threadedly connected to the screw rod 18. Connecting rods 21 are installed at both ends of the moving plate 20. The other ends of the two connecting rods 21 are installed at one end of the two connecting plates 7. The two ends of the two connecting rods 21 are respectively hinged to the moving plate 20 and the connecting plate 7. The thickness of the connecting plate 7 is slightly less than the internal space of the warning board 6. When the screw rod 18 rotates, the moving plate 20 can move up and down, so that the two connecting rods 21 rotate, and the connecting plate 7 can slide inside the warning board 6. Installation plates 22 are installed at the upper and lower parts of both ends inside the warning board 6. Rollers 23 are installed inside the installation plates 22. The rollers 23 are in contact with the upper and lower ends of the connecting plate 7. When the connecting plate 7 moves, the sliding friction becomes rolling friction, which is convenient for the movement of the connecting plate 7.

[0031] A fixing structure 5 is installed inside the upper end of the column 1. Through the fixing structure 5, the connecting plate 7 can be connected and fixed to the column 1, so that the warning sign can warn and restrict unauthorized personnel from approaching. The ends of the two connecting plates 7 away from each other are in a "mountain" shape. The connecting plate 7 can be inserted into the groove 4 and the lower end is inserted into the jack 3 for preliminary fixation.

[0032] The fixing structure 5 includes a cross bar 10. The cross bar 10 is fixedly installed inside the column 1. Sliders 11 are sleeved at both ends of the cross bar 10. Push rods 12 are fixedly installed at the lower ends of the two sliders 11. The push rods 12 are L-shaped. The push rods 12 penetrate through the column 1. A push plate 13 is installed at one end of the push rod 12 outside the column 1. A first inserting rod 14 is installed at one end of the push rod 12 inside the column 1. A slot 17 is opened at the upper end of the connecting plate 7 close to the column 1. The first inserting rod 14 is inserted into the slot 17 to fix the connecting plate 7.

[0033] A spring 15 is installed at one end where the two first inserting rods 14 are close to each other. The elastic potential energy of the spring 15 enables the first inserting rod 14 to be inserted into the slot 17. The other ends of the two springs 15 are installed at both ends of the block 16.

[0034] At one end of the two columns 1 away from each other, an insertion cylinder 8 is fixedly installed. Inside the insertion cylinder 8, there is a connecting insertion rod two 24. The connecting insertion rod two 24 is fixedly installed at one end of the column 1. The warning signs can be used in multiple combinations through the insertion cylinder 8 and the connecting insertion rod two 24. Insertion cylinders 8 are installed at both ends of the column 1 of the first warning sign, and connecting insertion rods two 24 are installed at both ends of the columns 1 of the other two warning signs. The three warning signs are surrounded into a concave shape. Inserting the connecting insertion rod two 24 into the insertion cylinder 8 can effectively extend the enclosure range of the warning signs, not only serving as a warning, but also enclosing the substation under maintenance to prevent unauthorized personnel from approaching accidentally.

[0035] During specific use, first press the push plates 13 at the upper ends of the two vertical plates 1. Through the push rods 12, the push rods 12 drive the sliders 11 to slide on the surface of the cross bar 10 to limit the direction. The push rods 12 drive the insertion rods one 14 to compress the springs 15 and move towards the inside of the column 1. Then insert the two connecting plates 7 into the grooves 4 inside the column 1. Release the push plates 13. Under the action of the springs 15, the insertion rods one 14 are inserted into the slots 17 to fix the connecting plates 7.

[0036] Rotate the turntable 19 to drive the screw rod 18 to rotate. The moving plate 19 moves up and down on the screw rod surface, driving the two connecting rods 21 to rotate, thereby driving the two connecting plates 7 to move inside the warning sign 6, and the distance of the connecting plates 7 can be adjusted, so as to control the coverage range of the warning sign.

[0037] Three groups of warning signs can be used in combination. Insertion cylinders 8 are installed at both ends of the column 1 of the first warning sign, and connecting insertion rods two 24 are installed at both ends of the columns 1 of the other two warning signs. The three warning signs are surrounded into a concave shape. Inserting the connecting insertion rod two 24 into the insertion cylinder 8 can effectively extend the enclosure range of the warning signs, not only serving as a warning, but also enclosing the substation under maintenance to prevent unauthorized personnel from approaching accidentally.

[0038] The above describes the present utility model and its implementation manners. Such a description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and, without departing from the purpose of the creation of the present utility model, design similar structural manners and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present utility model.
