Description

[Detailed explanation of the invention] <Industrial application field> This invention is applicable to pearl farming, fish and shellfish farming, etc.
An aquaculture cable that prevents underwater animals and plants attached to the cable from multiplying and reproduces by pouring hot water onto the aquaculture cable for suspending cages containing cultured organisms into the sea, and that can efficiently obtain the hot water. Regarding a hot water pouring device.

<Prior art> As shown in FIG. 5, a large number of floats 91 and suspension ropes 92 are connected to the aquaculture rope 9. The aquaculture rope 9 is floated on the sea surface by the float 91, and the suspension rope 92 is connected to the aquaculture rope 9. The connected cages 93 are sunk to a predetermined depth in the sea.

The cage 93 houses cultured organisms, and each time the cultured organisms are inspected, washed and disinfected with highly concentrated salt water, the cage is lifted into a work boat, and when the work is completed, the cage is suspended in the sea again.

The cage is pulled up by pulling up the aquaculture rope 9 using a pulling device installed on the work boat.

However, while the aquaculture cable 9 is floating in the sea for a long time, seaweed and shellfish adhere to the cable 9 and the float 91, and if this is left unattended, the attached substances will enlarge and propagate, making it difficult for the cable 9 to be pulled up. This will impede work, and the float 91 will no longer be able to support the cable due to the weight of the material attached to the cable.

In this case, the aquaculture cable 9 partially sinks significantly into the sea, and the suspension cable 92 suspending the cage 93 skids sideways so as to concentrate on the submerged part of the aquaculture cable 9, and the cage 93 sinks to the seabed. I had something to invite.

Therefore, in order to prevent the deposits from multiplying and multiplying on the aquaculture cables 9, hot water at 60 to 70° C. is poured onto the cables while the cables are being pulled up to the work boat. This is because when you pour hot water onto the cable, the attached seaweed and shellfish die and fall off the cable naturally within a few days.
In addition, it is possible to kill shellfish spores that have entered the minute gaps in the cables, which is more efficient than manual scraping off of deposits.

For example, Japanese Unexamined Patent Publication No. 59-45824 discloses a device that kills green seaweed adhering to fishing nets by spraying hot water onto them.
This device consists of a nozzle for spraying warm water onto fishing nets, a spray pipe equipped with a large number of these nozzles, a feed pipe connected to the spray pipe for supplying hot water, and a heater to supply hot water to the feed pipe. It consists of a water supply pump and a nozzle that sprays hot water onto the fishing net.

<Problems to be solved by the invention> However, the above-mentioned conventional device has the drawback that after hot water is sprayed onto fishing nets, it is discarded, and the hot water has to be re-produced, which increases the manufacturing cost. .

Therefore, the purpose of the present invention is to provide a hot water pouring device that can easily make hot water and reduce the overall cost by recovering the hot water poured over the raised aquaculture cables and floats and heating it again. There is a particular thing.

<Means for solving the problem> Therefore, the present invention has been made to achieve the above object, and its gist is to add hot water to the aquaculture rope and float pulled up by the aquaculture rope pulling device. a hot water delivery pipe connected to the nozzle, and a recovery heating device that collects and reheats the hot water that is hung on the aquaculture cables and floats on a base; The present invention relates to an apparatus for applying hot water to aquaculture cables, which includes a heating section that makes hot water using water supplied from a supply pipe, and a pump that sends the hot water heated by the heating section to the delivery pipe.

<Function> The device for sprinkling hot water onto aquaculture ropes of the present invention pulls up the aquaculture ropes and floats using a pulling device, pours hot water onto them from a nozzle, and collects and heats the hot water using a recovery heating device.

In addition, the two nozzles 7 and 7a on the boat side are installed at a higher position than the cable transition path so that the injection ports are slightly tilted downward, and the seaside nozzle 7b is installed at almost the same height as the cable transition path. Since the injection ports are slightly tilted upward, the hot water spouted from the high position nozzles 7 and 7a splashes over the cables, and the hot water jetted from the low position nozzle 7b hits the bottom of the float 91, causing the cables and Hot water can be effectively applied to the deposits on the lower part of the float 91.

In addition, since the wall plates 11 and 12 are provided on both sides of the cable transition path, even if the hot water injected from the nozzles 7, 7a, 7b hits the cables and the float 91 and rebounds, it will not reach the wall plates 11, 12. This prevents hot water from hitting the wall and splashing outside of the wall board, so there is no risk of burns to workers on the boat due to hot water splashing, and it also prevents hot water from splashing onto the sea and wasting hot water. can.

A part of the hot water spouted from the nozzle adheres to the cables and is taken out of the hot water spraying device 1 and is consumed.
Most of the hot water collects on the base 10 which also serves as a saucer, and is recovered to the recovery heating device 3 through the recovery pipe 33 and can be circulated and used.

Furthermore, the heating burner 46 heats the inside of the heating chamber 44 provided on the bottom side of the tank 41 and heats the heating tube 45 inside the chamber, while at the same time
The water inside can also be heated, and the heat from the burner 46 can be used efficiently, making it possible to further reduce fuel consumption.

As mentioned above, some of the hot water adhered to the cable 9 and was taken out of the hot water spraying device, but water equivalent to this taken out amount was passed from the water supply pipe 34 to the auxiliary tank 6,
It is possible to supply it to the supply pipe 31.

The auxiliary tank 6 is located directly above the opening of the chimney 43 and is heated by the high-temperature combustion exhaust gas from the chimney 43. Therefore, the water passing through the auxiliary tank 6 is made preliminary and then heated through the supply pipe 31. tube 4
It can be sent to 5.

Further, a downward peripheral wall 61 is protruded from the outer periphery of the auxiliary tank 6, and the combustion exhaust gas coming out of the chimney 43 collides with the auxiliary tank 6 and then wraps around downward along the peripheral wall 61 to reach the vicinity of the chimney 43. The water surface of the tank can be heated, and the heat from the burner 46 can be effectively used for heating the water.
