Description

Technical Field

[0001] The utility model relates to the field of ship power supplies, in particular to a lightning protection device for a ship container-type mobile power supply. Background Art

[0002] Ship container mobile power is a battery power system that uses the container body as a battery installation platform. Using container mobile power for ship power replacement, also known as "mobile power replacement", is a new type of battery installation for battery-powered ships.

[0003] Ship container mobile power supplies are usually placed on the open deck of the ship, and there is a possibility of being struck by lightning. Due to the particularity of the battery system, the disaster caused by lightning has a huge impact, and its lightning protection measures need to be considered. If its storage location is not within the scope of the ship's lightning protection design, it should have its own lightning protection measures. It is usually considered to discharge the direct lightning strike to the hull through the metal shell of the container of the container power supply, but since the steel thickness of the top plate and side plate of the ordinary container is generally 1.5-2.0 mm, this thickness cannot guarantee that it will not be broken down when receiving lightning strikes. According to the requirements of 5.2.7 of "GB50057_2010 Building Lightning Protection Design Code", when there are flammable items under the metal plate, the thickness of stainless steel, hot-dip galvanized steel and titanium plates should not be less than 4 mm, the thickness of copper plates should not be less than 5 mm, and the thickness of aluminum plates should not be less than 7 mm. Therefore, when the thickness of the iron plate is less than 4 mm, it may melt and burn the ship at the contact with the lightning strike channel, and the battery system in the box cannot be protected.

[0004] Therefore, a lightning protection device for a ship container type mobile power supply has been developed, which can protect the container shell from lightning and avoid failure and malfunction of the mobile power supply. Utility Model Content

[0005] In order to overcome the disadvantage that a ship container-type mobile power supply discharges direct lightning strikes onto the ship hull through the metal shell of the container of the container-type power supply, and fails to protect the battery system in the box, the utility model provides a lightning protection device for a ship container-type mobile power supply, which can protect the container shell from lightning and avoid failure and malfunction of the mobile power supply.

[0006] The technical scheme of the utility model is: a lightning protection device for a container-type mobile power supply of a ship, comprising a container, a first box frame, a first door, a second box frame, a second door, a first insulating block, a connecting plate, a lightning rod, a first grounding wire, a fixing bolt and a second grounding wire, the front side of the container is connected with the first box frame, the left and right parts of the first box frame are both rotatably connected with the first door, the first door is contacted and closed with each other, the rear side of the container is connected with the second box frame, the left and right parts of the second box frame are both rotatably connected with the second door, the second door is contacted and closed with each other, the left and right upper sides of the first box frame and the second box frame are both clamped with the first insulating block, the upper side of the first insulating block is detachably connected with the connecting plate through a plurality of bolts, the upper side of the connecting plate is connected with the lightning rod, the lower part of the lightning rod is connected with the first grounding wire, the first grounding wire is clamped with the fixing bolt, the fixing bolt is clamped and matched with the adjacent first insulating block, and the lower part of the fixing bolt is clamped with the second grounding wire.

[0007] Furthermore, both the first door and the second door are provided with handles.

[0008] Furthermore, lightning rods all have pointed ends.

[0009] Furthermore, a knob is provided on the upper side of the fixing bolt.

[0010] Furthermore, the fixing bolts are all made of conductive material.

[0011] Furthermore, it also includes a second insulating block. The lower sides of the left and right parts of the first box frame and the second box frame are both clamped with the second insulating blocks. The second insulating blocks are also clamped with fixing bolts, and the lower parts of the second grounding wires are clamped with the lower fixing bolts.

[0012] The beneficial effect is that when lightning strikes the lightning rod, the current passes through the lightning rod and then is connected to the hull through the first grounding wire and the second grounding wire, thereby achieving the effect of protecting the container shell from lightning and avoiding failure and malfunction of the mobile power supply.
