[0002] In recent years, there are many weeds in the irrigation canal, which poses a serious threat to flood control and drought relief. During normal drought relief, the amount of water diverted is reduced by one-third. During flood control, the water level of the canal is much higher than normal. In addition, water hyacinth has strong reproductive ability and vitality, and often grows in the river channel, which affects irrigation. As the temperature drops, water hyacinth enters a latent period, and its growth and reproduction are controlled. Therefore, winter is the best time to salvage water hyacinth. Fishing out water hyacinth can remove the seed source for next year and prevent it from reproducing and expanding. When the ship encounters thunderstorms, the danger of being struck by lightning will follow. Not only the equipment on the ship is in danger, but also the life safety of the personnel on the ship is difficult to guarantee. The ship is equipped with a lightning rod device on the top of the cabin to ensure the safety of the ship in thunderstorms and avoid being struck by lightning.

[0003] The existing lightning rods are relatively high. When a ship passes through a lower bridge tunnel, the lightning rods are likely to touch the bottom of the bridge, causing damage to the equipment. During installation, the overvoltage protection device body is generally connected to the hull with bolts. However, if the overvoltage protection device body is damaged, maintenance personnel need to use tools to remove it, which is time-consuming and labor-intensive. Utility Model Content
