2. Description of the Related Art As offshore structures such as offshore plants and offshore work platforms, bottom-mounted structures that are fixedly installed on the seabed and floating structures that are installed floating on the sea surface are known. In this type of marine structure, the outer surface of the structure, which is located below the sea surface, is constantly submerged in seawater and is therefore subject to corrosion and at the same time serves as a breeding ground for marine organisms. If the seawater flow rate is 3 knots or more, it will be physically difficult for marine life larvae to attach, but if there is a stationary structure such as a marine structure, marine life larvae will easily attach to it, and once it is The attached larvae do not easily detach. The main organisms that attach to marine structures and reproduce in this way include, for example, animals such as barnacles, serpulae, bryozoans, sea squirts, oysters, molluscs such as mussels, and plants. There are seaweeds such as green algae and brown algae. Particularly, barnacles, celluloids, bryozoans, and sea lettuce are highly viable, and their attachment to marine structures causes the following problems. In other words, since the frictional resistance between the structure and the seawater increases due to deposits, a tugboat with high horsepower is required when towing the structure, and the towing speed decreases.
In order to maintain speed, twisting costs increase significantly.
In addition, the deposits damage the coating of the structure, greatly accelerating corrosion. For this reason, conventionally, the work of manually scraping off the deposits using a scraper has been performed periodically. However, removing deposits using such a scraper is extremely difficult and inefficient, and requires a lot of manpower and time. In addition, there is a risk that the scraper may damage the coating film of the structure, and removal of deposits has become a major problem in the maintenance of marine structures.

According to the device for removing deposits of this invention, by rotating the tips of the inner cutter and the tips of the outer cutter with the ends roughly aligned and pressing them against the deposits on the marine structure, it is possible to easily remove the deposits. and can be removed reliably. Since the cutter scrapes off the deposits while rotating, the deposits can be removed very efficiently. In addition, even when scraping off deposits in this way, the outer cutter can move slightly in the axial direction relative to the moving member, that is, the inner cutter, and the outer cutter receives a backward force by sending a water stream forward by rotation. Therefore, even if the inner cutter reaches the outer surface of the structure, the outer cutter will not be strongly pressed against the outer surface of the structure, and there is less risk of damaging the paint film on the outer surface of the structure. Furthermore, when starting work, the thickness and hardness of the deposit can be determined by pressing only the inner cutter against the deposit and scraping it off with the outer cutter set back from the inner cutter. moreover,
By spouting water from the tip of the inner vine, it is possible to blow off the deposits scraped off by the vines from the roots. It can be prevented from getting caught between the outer surface and the stub, and from this point of view as well, there is less risk of damaging the coating on the outer surface of the structure.

First, a diver enters the sea near the marine structure 1 with the deposit removal device 4, and removes the debris 24, 26.
The cutters 24 and 26 are rotated by the motor 21 while facing the deposit 2 on the outer surface of the structure 1 located below the sea surface. At first, the outer cutter 26 is moved back from the inner cutter 24 as shown by the chain line in FIG.
When the inner cutter 24 reaches the outer surface of the structure 1, it is temporarily retreated to the outside of the deposit 2. The thickness and hardness of the deposit 2 can be determined by the pressing force of the inner cutter 24 at this time.

Next, the outer cutter 26 is advanced to almost the same position as the inner cutter 24, and the tips of the claws 49 of the cover 29 are pressed against the deposit 2, and both rotating cutters 24 and 26 are pressed against the deposit 2. Scrape this off. At this time, depending on the thickness and hardness of the deposit 2, for example, a lever (not shown) attached to the case 20 is operated to adjust the rotation speed of the cutters 24, 26, that is, the rotation speed of the motor 21. Katsuta 2
When the cutters 4 and 26 move forward while scraping off the deposits 2, the cover 29 also moves forward, but the claws 49 are pressed against the deposits 2 around the cutters 24 and 26 and remain stopped. And Katsuta 24, 26
The deposits 2 scraped off by this do not scatter outside the cover 29 and fall into the collection bag 54 from the cover 29 discharge port 52 through the discharge pipe 53.
When the cutters 24 and 26 reach the outer surface of the structure 1, move them appropriately and remove both the cutters 2.
4 and 26, the surrounding deposits 2 are removed in the same manner as above.
scrape off. Even when scraping off the deposits 2 in this way, the outer cutter 26 can move slightly in the axial direction relative to the movable member 27, that is, the inner cutter 24, and the outer cutter 26 rotates to send the water flow forward and backward. Because it receives the force of the inner cutter 2
Even when the outer cutter 4 reaches the outer surface of the structure 1, the outer cutter 26 is not strongly pressed against the outer surface of the structure 1, and there is little risk of damaging the coating film on the outer surface of the structure 1. Furthermore, while the cutters 24 and 26 are scraping off the deposits 2, the jet water is jetted from the tip of the inner cutter 24 by the jetting device 30 so as to blow away the scraped deposits 2. do. In this way, the scraped deposit 2 will not be caught between the outer surface of the structure 1 and the cutters 24, 26, and the risk of damage to the coating on the outer surface of the structure 1 will be further reduced. Further, by jetting jet water, it is possible to locally peel off the deposits 2 or to blow away the scraped deposits 2 from the roots. Note that by spraying jet water while the cutters 24 and 26 are stopped, the deposits 2 are scraped off.
You can also make it blow away. Also, if the collection bag 55 is full of deposits 2,
For example, after removing the lid 55 and emptying the bag 54 on the offshore structure 1 or a work boat, the operation is repeated again.
