[0001] The utility model relates to the technical field of five-prevention locks, in particular to a waterproof mechanism for a five-prevention lock in a substation. Background Technique

[0002] The five-prevention mechanical program lock is mainly used in the power system during the switching operation process of the substation to force the operators to operate in accordance with the power operation procedures and programs. The five-prevention mechanical locks are widely installed in the substations of the power system. In addition to forcing the operators to follow the operation procedures, it can also prevent misoperations during the operation process. The five-prevention locks have a strong protective function for the operating substation equipment and the safety of the operators. Only by opening the lock in a timely and accurate manner can the next switching operation be carried out.

Then, by controlling the limiting member 18, the limitation of the drainage groove 16 is cancelled, and then the drainage groove 16 is slid to drive the connecting platform 15 to adjust the two connecting platforms 15 to be adapted to the five-prevention lock body 19. Finally, by controlling the limit plate 17 again, the fixing effect on the connecting platform 15 is achieved; at this time, the two sealing plates 23 will be in a mutually attached state under the action of the support spring 24, thereby driving the two bellows waterproof covers 22 to unfold and realizing the waterproof effect on the five-prevention lock body 19, effectively avoiding the situation that it is damaged due to rainwater entry during its use.

[0027] II. During actual use, when it rains, the rainwater falls on the rain shield 13. At this time, the rain shield 13 can block the rainwater, thereby avoiding it from entering the waterproof component 2 through the gap between the installation platforms 12. At the same time, because the top of the rain shield 13 is an inclined plane, it can prevent rainwater from accumulating on its top, enabling the rainwater to flow into the drainage grooves 16 opened on the tops of the sliding platforms 14 through both sides, and finally discharging the rainwater under the action of the drainage grooves 16. This effectively ensures its waterproof effect.
