The power supply grooves 15 are rectangular, the power supply pieces 16 are U-shaped, the power supply pieces 16 are elastic, the left side and the right side of each power supply piece 16 are arc-shaped protruding inwards, and the power taking pieces 14 are inserted into the power supply pieces 16.

The power supply piece 16 is clamped in the corresponding power supply groove 15 by means of elasticity, and the two sides of the power supply piece 15 are arc-shaped, so that the power taking piece 14 and the corresponding power supply piece 16 are kept in a clamping state, the power supply is more reliable, and the phenomenon of virtual connection cannot occur when the power supply piece 16 and the power taking piece 14 slide relatively.

As shown in fig. 7, the left and right sides of the rear portion of the slider 13 are parallel planes, the distance between the two planes is smaller than the width of the notch of the T-shaped groove, the upper and lower sides of the rear portion of the slider 13 are arc-shaped, and the power supply piece 16 is located at the lower side of the slider 13. The housing 17 is circular.

When one of the type blocks 2 needs to be replaced due to any reason, the type block 2 can be inserted from the notch of the T-shaped groove after being rotated by 90 degrees at the position shown in figure 7, and then the power taking piece 14 is inserted into the power supply piece 16 after being rotated by 90 degrees, so that the type block 2 adjacent to the type block 2 can be detached without pushing the type block 2 out of the end of the track 3.

As shown in fig. 4, a vertical second blind hole 12 is formed in the upper portion of the slider 13, a positioning block 10 is slidably connected to the second blind hole 12, a spring 20 is arranged between the lower end of the positioning block 10 and the slider 13 in the second blind hole 12, and the upper end of the positioning block 10 abuts against the upper surface of the T-shaped groove.

The slider 13 is clamped in the T-shaped groove by the spring 20 and the positioning block 10.

As shown in fig. 7, the upper end of the positioning block 10 is a flat surface for matching with the side surface of the T-shaped groove. The slider 13 is positioned in the circumferential direction by the engagement of the flat surface and the T-shaped groove, thereby aligning the characters on the character plate 19 and preventing the characters from being inclined or misaligned due to the inclination of the character plate 19.

The using process of the invention is as follows:

the type blocks 2 are inserted from the notch of the T-shaped groove in sequence according to the arrangement sequence of the identification characters, and are rotated to enable the power taking sheet 14 to be inserted into the corresponding power supply sheet 16, and then the type blocks 2 are pushed to adjust the gaps between the type blocks.

During daytime, the electric energy converted by the solar cell panel 6 is stored in the storage battery 7, and at night, the controller supplies power to the movable character block 2 according to preset time, so that characters on the signboard are also very striking at night and are easy to identify. In the daytime, the controller stops supplying power to the type block 2 according to the preset time.

When the content of the signboard is required to be changed due to the change of the line of the transformer substation, the box cover 5 is only required to be taken down, the character plate 19 corresponding to the character to be changed is detached, then the corresponding character plate 19 is replaced, and the box cover 5 is buckled, so that the whole signboard does not need to be replaced, the cost of the character plate 19 of acrylic is low, the waste is reduced, the character content of the signboard is rapidly changed, and the time for changing the character is reduced.

The controller can also control the movable character block 2 according to the intensity of illumination, and automatically lighten the movable character block 2 when the illumination is insufficient, so that the characters on the movable character block 2 can be highlighted in cloudy days.

By adopting the solar cell panel 6, the invention has the following characteristics:

1. the installation is simple: the purpose of supplying power to the backlight plate 18 can be achieved without laying complicated lines or laying complicated lines.

2. The cost is low: the maintenance or replacement of the line and other configurations is not required to be carried out uninterruptedly for a long time, and the maintenance cost is low. Because the device is one-time investment, no slow post maintenance is needed.

3. No potential safety hazard: the invention is an ultra-low pressure product, and the operation is safe and reliable.

4. The device is green and environment-friendly, simple and convenient to install, free of maintenance and low in maintenance and management cost.

The invention can be used for the outgoing line interval of the transformer substation and can also be widely used in various occasions needing identification.

The above-mentioned embodiments are described in detail and specifically for the purpose of illustrating the technical ideas and features of the present invention, and it is an object of the present invention to enable those skilled in the art to understand the contents of the present invention and to implement the same, but not to limit the present invention only by the embodiments, and it is not limited to the scope of the present invention, i.e. equivalent changes or modifications made within the spirit of the present invention, and it is within the scope of the present invention for those skilled in the art to make local modifications within the system and changes or modifications between subsystems without departing from the structure of the present invention.
