The bidirectional water pump 6 is used to realize the bidirectional delivery of seawater between the seawater storage tank 10 and the seawater dry-wet alternating area water tank 3. Through the bidirectional water pump 6, seawater in the seawater storage tank 10 can be delivered to the seawater dry-wet alternating area water tank 3 to realize the wet exposure environment.
