Description

Ocean current profile observation raft, arrangement method and ship-mounted fixed point observation system

Technical Field

The invention belongs to the technical field of ocean current observation, and particularly relates to an ocean current profile observation raft, a layout method and a ship-mounted fixed point observation system.

Background

At present, the oceans survey the distribution and change rules of hydrology, meteorology, physics, chemistry, biology, substrate in a specific sea area. The investigation observation mode includes large-area investigation, section investigation, continuous observation and auxiliary observation. The method comprises aerial observation, satellite observation, ship observation, underwater observation, automatic observation of a fixed buoy, automatic observation of a floating station and the like. The marine survey has important significance for mastering the distribution condition of aquatic resources and fishery production. Ocean current profile observation rafts are also mechanical equipment frequently used in marine investigation, and are mainly used for shipboard observation, particularly offshore investigation. At present, no professional observation device of this type is available for on-board ship observation in open sea surveys.

Through the analysis, the problems of the prior art are as follows:

(1) the on-board raft is mainly used in offshore surveys. The ocean current observation mode/device is beneficial and can be supplemented, and the application of the ocean current observation mode/device in open sea is less.

(2) The existing observation raft has insufficient strength and insufficient data observation stability under the poor sea condition and on the premise of transmitting data in real time. The difficulty in solving the above problems is: in poor sea conditions, the strength of the raft and the strength of the connection between the raft and a ship or an instrument are absolutely required to be considered. Meanwhile, how to ensure that the observed ocean current data are transmitted back to the ship in real time when the raft is normally observed is also a problem to be considered.

The significance for solving the problems is as follows: due to the lack of professional equipment, the observation raft is a beneficial observation method, and the utilization rate of the observation raft in open sea is not very high. The problems are solved, and the use range, the use frequency and the use effect of the observation raft can be effectively increased.

After the connection is finished, (E) is responsible for assisting (C) to convey the support rod 1 to the outside of the ship.

And (C) conveying the support rod to the middle connecting buckle 3 of the support rod, and (C) connecting a stainless steel shackle 24 on the thin anchor chain 23 and the thick nylon rope 22 with the middle connecting buckle 3 of the support rod, after the connection is finished, (E) assisting the support rod 1 to be conveyed outwards continuously, and after the support rod 1 is conveyed out of the ship board for about 3.5 meters, fixing the support rod 1 on the U-shaped bolt 6 by using an iron plate and a nut.

When the supporting rod 1 is fixed, safety ropes (a bow safety rope 15 and a stern safety rope 16) on two sides are tightened (A and B) and tied on a ship board.

After the support rod 1 and the safety ropes (the bow safety rope 15 and the stern safety rope 16) are fixed, the crane completely puts the equipment into the sea, the steel wire cable 17 is not stressed any more, at the moment, the steel wire cable 11 is pulled back to the side of the ship by the return rope 19 and is taken off from the crane, the safety buckle 18 at the top end of the steel wire cable 11 is buckled on the movable rope buckle 5 of the support rod 1, and the return rope 19 takes root on the ship.

The fixed anchor chain 8, the thin anchor chain 23, the thick nylon rope 22, the support rod protection rope (the support rod middle protection rope 9 and the support rod top protection rope 10) and the outer safety rope 20 at the tail part of the support rod are rooted on the ship one by one.

At the moment, the laying work is finished, and the equipment condition is observed once again, so that corresponding improvement is made.

4. Plant recovery process

The total number of the equipment recovery needs 5-6 persons, wherein 1 person operates the crane, 2 (A and B) persons are responsible for the safety ropes on the two sides of the raft (the bow safety rope 15 and the stern safety rope 16), and 2-3 (C and D) persons are responsible for the disassembly work of the ropes (the outer side safety rope 20, the thick nylon rope 22, the thin anchor chain 23 and the ADCP data transmission cable 29) and the supporting rod 1.

Before the equipment is recovered, required tools (a rolling belt, scissors and a spanner) are prepared, a small door on one side of a ship board is opened, and work clothes, safety helmets and safety shoes are worn, so that personal safety is paid attention to.

The steel cable 17 is pulled back to the side of the ship by a return rope 19 and hung on a crane, and the equipment is lifted to enable the crane to be stressed.

Firstly, the connection part of the fixed anchor chain 8, the thin anchor chain 23, the thick nylon rope 22, the support rod protection rope (the support rod middle protection rope 9 and the support rod top protection rope 10) and the outer safety rope 20 at the tail part of the support rod and the ship is loosened.

(pent-gamma) the iron plate and nut of the U-bolt 6 of the fixing stay 1 were removed using a wrench. After loosening, (E C) the strut 1 is drawn back to the middle connecting buckle 3, and then the stainless steel shackles 24 on the thin anchor chains 23 and the thick nylon ropes 22 and the strut middle connecting buckle 24 are disassembled.

And (C) withdrawing to the connecting buckle 4 at the head of the support rod, and (C) disassembling the safety rope safety buckle 21 at the outer side and the connecting buckle 4 at the top end of the support rod.

After the disassembly is finished, the safety ropes at the two sides (the bow safety rope 15 and the stern safety rope 16) can be loosened from the side of the ship. After all the ropes (the outer safety rope 20, the thick nylon rope 22, the thin anchor chain 23 and the ADCP data transmission cable 29) are untied, the crane lifts the ropes, and the equipment is lifted to pass through the safety wall on the side of the ship board until the ship board stays.

The equipment is put on the deck and the wire cable 17 is taken off the crane.

And (5) the whole set of equipment is inspected to be free from damage and collision, and corresponding improvement is made according to the condition. The ropes are smoothed out neatly, and the equipment is arranged properly.

At this point the recovery work is complete.

During the period of 5-9 months in 2020, the ocean current profile survey raft is placed on a tugboat in the north sea area of the south sea (the placement mode is shown in fig. 6), and internal wave current on-board monitoring is carried out for up to 108 days. The sea surface can experience severe sea conditions such as typhoon for many times during the period, and the use effect is good.
