Description

The present invention relates to a liquid quantitative delivery device that is placed on a ship and delivers a fixed amount of liquid overboard.

Conventionally, when water quality needs to be improved due to pollution of water areas such as the sea, rivers, and lakes due to environmental pollution, etc., or in order to make a limited water area such as a cage for fish farming suitable for fish. Chemicals and the like are put into the water area.

For example, since parasites parasitize the body surface of fish such as campachi, if it is a farmed fish, the farmed fish that dislikes parasites rub their bodies against the net or fence and repeat the action to remove the parasites. Since the body surface is damaged and cannot be sold, a drug to exterminate parasites is put into the fish cage.

In addition, a chemical solution consisting of hydrogen peroxide solution, which is a powerful oxidizing agent, is known to remove parasites. For farmed fish cultivated in sea cages, the ship is close to the cage and the worker is in the cage. Moving to the scaffolding on the periphery, multiple people scoop up the farmed fish in the cage together with seawater with a special sheet, and a worker wearing protective equipment such as protective gloves holds a container containing the chemical solution there. The worker moves from the ship to the foothold around the cage and puts the chemical solution into the sheet of the cage by himself, but it is necessary for multiple people to put in the amount commensurate with the scale of the cage, and if the number of people is small, it will be transported. The input must be repeated.

In addition, farmed fish that have been scooped up together with seawater on a special sheet will be weakened due to lack of oxygen in about 15 minutes, and in the summer in 10 minutes, so it is necessary to hurry from scaffolding to adding chemicals. Therefore, it is very dangerous for the worker to carry a heavy container containing a chemical solution such as hydrogen peroxide solution on the ship or on the unstable scaffolding around the cage, and it is very dangerous for multiple people to work. It is mandatory.

It should be noted that it is not realistic to fill a container with a sufficiently diluted hydrogen peroxide solution and carry it because there is a concern that the number of times of transportation will be significantly increased, additional workers will be added, and the working time will be prolonged. The concentration of hydrogen peroxide solution is relatively high, and the amount of chemical solution used for one cage must be an appropriate amount according to the scale of the cage.

In such fish farming, for example, the "pest control tool for fish farming" described in Patent Document 1 has been devised, and this technique has a large number of irregularities such as a large number of wart-like protrusions or linear protrusions on the outer surface. Heavy objects such as metal and earth and sand are packed in the bag body, and a floating body is attached to the bag mouth to install it in the water in the cage.

In other words, instead of rubbing the body against the cage net or fence, the farmed fish floats the pest control tool for fish farming on the cage so that it does not damage the body surface even if it rubs the body, which is excellent in that it does not use chemicals. However, it only reduces the rate of rubbing the body against the cage net and fence, and even if the pest control tool for fish farming is used, parasites that cannot be completely removed remain, so it is universal for many farmed fish. It was not realistic to get rid of parasites without fail.

In fish farming, a safe and convenient method for injecting chemicals has not yet been established, but as a technology used for purification treatments targeting vast water areas, chemicals can be efficiently diffused into water using ships, etc. A method of mixing is disclosed in Patent Document 2.

According to the "chemical spraying method" according to the present technology, a chemical injection nozzle is provided on the hull side above the screen of the ship toward the rear, and a desired amount of chemical is mixed into the compressed gas from the ship into the chemical injection nozzle. The mixed fluid is supplied, and the chemicals are diffused and mixed into the water from the navigating ship.

That is, the chemicals ejected into the water are diffused and mixed by utilizing the action of the screw to diffuse the water.

Certainly, the "method of spraying chemicals" according to Patent Document 2 is excellent in that it is possible to diffuse and mix chemicals with high efficiency in a water area where a ship can navigate, and it is possible to purify a wide area with water.

However, in this method, since the chemical injection nozzle is arranged near the screen of the ship and is integrally configured with the ship, it is necessary to move the ship itself to the area in order to spray the chemical in the water area of a specific area. It was extremely difficult to apply it to the spraying work in the area where the ship was not easily accessible because it was physically surrounded by a cage net or the like.

In addition, since the feeder and valve are electrically controlled to adjust the opening and spray a fixed amount of chemicals, the use of a strong reactive chemical such as hydrogen peroxide solution may cause a risk of ignition or failure at the component level. It tends to be difficult, and it is disadvantageous in terms of maintenance safety, operating cost, and manufacturing cost.

In addition, in order to spray chemicals in water bodies, even if they are sprayed in a specific area, a large amount of chemicals is required, so it is inevitable that the chemical tank will become larger. There is always a chemical tank on board even when no work is being performed, which greatly impedes workability on board during normal navigation.

The present invention has been made in view of the above circumstances, and is safe, resistant to failure, excellent in maintainability, and moreover, a predetermined liquid is surely injected from the ship even in a specific local area.

As described above, the liquid quantitative delivery device 1 according to the present embodiment is configured, and is a device that is mounted on the ship U and sends out a fixed amount of liquid L to the outboard G, and accommodates the liquid L. The storage tank section 2, the metering container section 21 that quantitatively fills the liquid L in the storage tank section 2 by gravity, and the liquid in the metering container section 21 that is provided with a valve 36 at the base end portion 37 and communicates with the metering container section 21. The storage tank unit 2 is composed of a delivery unit 35 that sends L to the outboard G by gravity, and a guide unit 15 that is provided with valves 16 and 19 and communicates the storage tank unit 2 and the metering container unit 21. The metering container section 21 is provided with an engaging section 13 that engages with the transport machine and can be freely transferred, and is formed in a flat box shape having a substantially sealed metering space 22 for accommodating the liquid L, and a metering space is above the metering space.

If a chemical-resistant synthetic resin material is used, even a strong liquid L having reactivity such as hydrogen peroxide solution can be used.

Further, when the liquid L is filled in the metering container section 21, the air in the metering space 22 and the excess liquid L can be released from the air bleeding section 29 to the storage tank section 2, so that the liquid L such as hydrogen peroxide solution can be released. Even if the air is used, it can be safely released from the air bleeding portion 29 to the storage tank portion 2 without scattering to the outside, and the work on the unstable ship U can be safely performed.

Further, the delivery unit 35 is equipped on a ship equipped with a general internal combustion engine by forming a mixing unit 44 provided with a valve 49 that allows the diluting liquid K to be freely mixed in the vicinity of the base end portion 37. The liquid L can be easily diluted by pouring seawater or the like discharged outboard after being pumped by the engine cooling pump and used for cooling the engine into the mixing section 44, and further, the liquid can be diluted. The delivery speed of L can be improved, and the inside of the pipe of the delivery unit 35 can be easily cleaned.

Further, since the quantitative container unit 21 forms the confirmation windows 28a and 28b that allow the amount of the liquid L in the quantitative space 22 to be visually recognized, the filling condition of the liquid L in the quantitative space 22 can be easily confirmed. ..

Further, since the discharge unit 39 forms a floating body 42 that can float freely in water or at a predetermined position on the water surface, it becomes easy to pinpoint the liquid L to the injection target point in the target water area.

Further, if the liquid L has a specific gravity heavier than that of the water area, the liquid L can be evenly added so as to gradually dilute from the vicinity of the water surface toward the water.

Although the preferred embodiment of the liquid quantitative delivery device 1 according to the present embodiment of the present invention has been described above, the present invention is not limited to a specific embodiment, and various modifications and changes can be made.
