Description

A closed living water tank on a fishing boat

technical field

The invention relates to a water tank for temporarily raising live fish, in particular to a closed live water tank arranged on a ship.

Background technique

When inshore fishermen work at sea, they sometimes catch some surviving fish, some of which have high economic value and strong vitality, and can be temporarily raised on board without dying. If they are transported back to the wharf for sale, these The price of live fish is often dozens of times that of dead fish, and the economic value is very considerable. Therefore, some fishermen privately set up an open-air living pool on the deck to temporarily raise live fish.

However, there is a free liquid surface in such a living pool, which will seriously reduce the stability of the ship. In addition, it is located at a higher center of gravity on the deck, which will have a more adverse impact on stability. Therefore, the ship inspection agency strictly prohibits the installation of such a living pool. However, driven by economic interests, fishermen set up living pools privately. The consequence of this is that the living pool is set up after the fishing boat is completed, skipping the inspection link before the ship's operation, and the damage to the stability of the living pool becomes impossible to consider, causing safety hazards to fishery production. Therefore be necessary to design a kind of closed living water tank to meet the needs of fishermen.

Contents of the invention

The technical problem to be solved by the present invention is to provide a closed living water tank on a fishing boat with reasonable structural design and safe use in view of the above-mentioned technical status quo.

The technical solution adopted by the present invention to solve the above-mentioned technical problems is: a closed living water tank, including a box body, which is characterized in that: the box body is arranged in the middle of the deck of the hull, and the upper opening of the box body is fitted with a hatch cover , the side of the box is provided with a water inlet, the bottom of the box is provided with a drain, the water inlet is connected to the water supply pipe, a seawater pump is provided on the water supply pipe, the outlet is connected to the drainage pipe, and the bottom of the hull is provided with a seabed The door, the seabed door is connected with the water supply pipeline and the drainage pipeline.

As an improvement, the box body is arranged symmetrically along the central axis of the hull, there are no less than two water inlets, which are arranged on the left side of the box body, and two water outlets, which are arranged at the bottom of the box body near the right side.

As an improvement, the water supply pipeline is laid down from the left water inlet of the box body along the bottom of the hull to the seabed door, and the drainage pipeline is laid down from the bottom outlet of the box body along the bottom of the hull to the bottom door.

As a further improvement, the seawater pump is a miniature water pump installed on the water supply pipeline near the seabed door.

Further improvement, the outer edge of the hatch cover is embedded with a first sealing ring to seal the upper opening of the box body, the hatch cover is provided with lifting lugs for easy lifting by a crane, and an openable opening is provided at the corner of the hatch cover. the trap door.

Preferably, there are two lifting lugs on the left and right, one side of the valve is connected to the hatch cover through a hinge, the valve is provided with a handle for easy opening, and a second sealing ring is lined between the outer edge of the valve and the hatch cover.

As an improvement, the box body is sealed and inserted into the partition plate through the guide rail structure in the middle part, so that the box body is divided into at least two sub-boxes, wherein at least one sub-box is connected to the gas tank through the air supply pipe and the air supply valve, and An exhaust pipe and an exhaust valve are arranged on the top of the sub-casing.

Finally, the sub-box is provided with a bait hopper that can slide near the valve.

Compared with the prior art, the present invention has the advantages of setting a water inlet and a water outlet, communicating with external seawater through pipes, and realizing the replacement of seawater in the box, so that there is sufficient oxygen in the box for fish to survive. The structure design of the invention is reasonable, and the stability calculation is included in the design stage, so that the influence of the living water tank on the stability is changed from uncontrollable to controllable, which not only eliminates the influence of the free liquid surface and hidden dangers in safety, but also ensures the economic safety of fishermen. Benefits; especially the addition of an air tank can properly pressurize the seawater in the sub-box, making it easier for deep-sea fish to survive, and provide a proper amount of oxygen to increase the survival rate of fish, and add a bait hopper that can slide, which is convenient Feeding, reducing mortality, can greatly improve the freshness of fishing products and increase fishermen's income.

detailed description

The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

As shown in Figures 1 and 2, a closed living water tank on a fishing boat includes a box body 1 and a hatch cover 4 that is arranged on the box body 1. The box body 1 is arranged in the middle of the deck of the hull 9, along the The central axis is arranged symmetrically, two water inlets 11 are provided on the left side of the box body 1, and two drain outlets 12 are provided on the left side of the bottom of the box body 1. The water inlets 11 are connected with the water supply pipeline 2, and the water supply pipeline 2 There is a seawater pump 6, the outlet 12 is connected with the drainage pipe 3, the bottom of the hull 9 is provided with a seabed door 7, and the seabed door 7 is connected with the water supply pipe 2 and the drainage pipe 3; The water outlet 11 is laid downwards along the inner bottom of the hull 9 to the seabed door 7, and the drainage pipe 3 is laid downwards from the bottom drain 12 of the casing 1 to the seabed door 7 along the inner bottom of the hull 9. The seawater pump 6 is a miniature water pump installed in the water supply The position on the pipeline 2 close to the seabed door 7, such that the seawater enters the water supply pipeline 2 through the seabed door 7 through the suction of the seawater pump 6, and the seawater in the water supply pipeline 2 enters the box body 1 through the water inlet 11 on the side of the box body 1 , the seawater in the box 1 is discharged from the water outlet 12 at the bottom of the box to the hull 9 through the drainage pipe 3, so as to realize the replacement of seawater in the box; The opening is sealed, and the hatch cover 4 is provided with two lifting lugs 41 that are convenient to the lifting of the crane. The valve 5 that can be easily opened, the size of the valve is 60mm × 60mm, one side of the valve 5 is connected with the hatch cover 4 through a hinge 8, the valve 5 is provided with a handle 51 that is easy to open, the outer edge of the valve 5 is connected to the hatch cover 4 There is a second sealing ring between them.

During use, the captured live fish can be temporarily kept in the box body 1, and the water supply and drainage of the box body 1 are carried out through the water supply pipe 2 and the drainage pipe 3, so that there is sufficient oxygen in the box body 1 for the fish to survive, and the fish is supplied to the box body at ordinary times. When throwing live fish in 1, only need to open valve 5 and get final product, catch catch and need to open hatch cover 4, hang on the lug of hatch cover 4 by crane, sling, just hatch cover 4 can be opened, safe to use Convenience.
