[0023] See also Figures 1 to 4 , the utility model provides a technical solution:

[0024] Embodiment 1, a stable wiring mechanism for improving the reliability of nuclear power equipment, the stable wiring mechanism for improving the reliability of nuclear power equipment includes: an equipment box 1.

[0025] Specifically, an installation rack 2 is fixedly connected to the inner side of the equipment box body 1. A wire passing hole 3 is opened at the lower end of the equipment box body 1. A plurality of electrical components 4 are fixedly connected to the side surface of the installation rack 2. A pressing plate 5 is slidably inserted on one side of the electrical component 4. Two symmetrically arranged bolts 6 are rotatably inserted on one side of the pressing plate 5. The bolts 6 are threadedly inserted into the electrical component 4. A plurality of fixing plates 7 corresponding to the positions and quantities of the bolts 6 are fixedly connected to the side surface of the installation rack 2. A fixing rod 8 is slidably connected to one side of the fixing plate 7. One end of the fixing rod 8 is fixedly connected with a limiting block 9 arranged in a "V" shape. A spring 10 is fixedly connected between the limiting block 9 and the fixing plate 7. During specific implementation, first, the electric wire is passed through the wire passing hole 3 into the equipment box body 1, and then fixedly connected to the electrical component 4. Then, the pressing plate 5 is slidably inserted into the electrical component 4, and the bolts 6 are threadedly inserted into the electrical component 4 to fix the pressing plate 5 on the electrical component 4, thereby pressing the electric wire tightly. Then, the control of the limiting block 9 is released. The limiting block 9 will slide towards the bolt 6 end under the action of the spring 10 and then be clamped with the bolt 6. Moreover, the "V"-shaped limiting block 9 can adapt to bolts 6 of various sizes, improving the applicability of the present device. In this way, it can be ensured that the bolt 6 will not loosen when the cooling fan works and vibrates, thereby ensuring the stability of the electric wire installation and further improving the reliable use of the nuclear power equipment.

[0026] In order to further improve the limiting effect of the limiting block 9, a plurality of card slots 15 are opened on the side surface of the limiting block 9 in contact with the bolt 6. The plurality of card slots 15 are linearly and arrayedly distributed on the side surface of the limiting block 9. The card slots 15 can enable the limiting block 9 to be better clamped with the bolt 6, thereby better restricting the rotation of the bolt 6.

[0027] In order to prevent the fixing rod 8 from sliding out of the fixing plate 7, a connecting plate 11 is fixedly connected to one end of the fixing rod 8. The fixing plate 7 is located between the limiting block 9 and the connecting plate 11. The connecting plate 11 can block the fixing rod 8 to ensure that the fixing rod 8 will not slide out of the fixing plate 7 under the action of the spring 10.

[0028] In order to facilitate the restriction of the limiting block 9, a clamping block 12 is slidably connected to the side surface of the connecting plate 11. The clamping block 12 is arranged in a "soil" shape. When installing and disassembling the bolt 6, the limiting block 9 is slid towards the fixing plate 7 end, and then the clamping block 12 is slid down to be clamped between the connecting plate 11 and the fixing plate 7, so as to restrict the sliding of the limiting block 9, thereby freeing both hands to install or disassemble the bolt 6. And the "soil"-shaped clamping block 12 can ensure that the clamping block 12 will not tilt and shake when sliding.

[0029] In order to facilitate the sliding installation of the fixing rod 8 and the block 12, a sliding groove 14 for the sliding installation of the block 12 is opened on the side of the connecting plate 11 of the present application, and a sliding hole 13 for the sliding insertion of the fixing rod 8 is opened through the side of the fixing plate 7. The sliding hole 13 can facilitate the sliding insertion of the fixing rod 8 and the fixing plate 7, and the sliding groove 14 can facilitate the sliding connection of the block 12 and the connecting plate 11.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
