Abstract

PURPOSE:To smoothly wash a ship by taking out a cooling water which has just cooled an engine through a branch passage branched off from a cooling water passage and providing a stop valve on said branch passage. CONSTITUTION:A water pump 32 is driven by an intermediate transmission shaft 26, and feeds under pressure sea water around a ship 10 which is taken in from a water inlet port 34, and the like, into a water feed passage 36 as a cooling water. The chief route of the cooling water is one which discharges the water out into water via a discharge passage 44. On the other hand, the other route is a branched passage 46 which is branched off immediately before a temp. sensing valve 40. And, a stop valve 56 is provided on the passage 46 on the outside of a bottom cowling 22 of a connecting pipe 48 and, further, a hose is connected to its end part. Thus, it is not necessary to separately use a pump., etc. or to use a power for scooping up water, and the like.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a cleaning device for a ship, and particularly to a cleaning device for a ship equipped with a water-cooled engine.

[Prior Art] Conventionally, tap water or seawater pumped around the ship has been used to wash ships. However, when using tap water, there are locational constraints such as having to be near a ship or a water tap, and there is also the problem that pumping water with a bucket requires a lot of labor on the part of workers. There is.

[Problems to be Solved by the Invention] The present invention was devised in view of the drawbacks of the prior art, and aims to solve the problem without being restricted by location and requiring a large amount of labor. An object of the present invention is to provide a ship cleaning device that enables the ship to be washed without any cleaning.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a branch system in which cooling water immediately after cooling the engine is branched from a cooling water passage in a ship equipped with a water-cooled engine. It can be taken out through a passage, and a shutoff valve is provided in the branch passage.

[Function] According to the cleaning device of the present invention, since the cooling water that cools the engine is energized by the two-way pump, this cooling water can be removed by taking out the cooling water immediately after cooling the engine through the branch passage. Can be used for cleaning ships. The cooling water immediately after cooling the engine is
It is heated by heat exchange with the engine, so you can use warm water to clean it even in the winter. Also, since it is washed with warm water, it is easy to remove dirt.

[Example] Hereinafter, the present invention will be explained based on embodiments shown in the drawings.

1 and 2 show an embodiment in which the present invention is applied to a boat having an outboard motor.

In Figure 1, the hull of the ship is not indicated by the symbol lO.
A clamp flaket 14 is attached to the stern plate 12 of this hull 10.
An outboard motor 16 is attached via the.

The engine 18 of the outboard motor 16 is covered by a collar link 20, and the open lower end of the collar link 20 is attached to a bottom cowling 22, which is connected to a casing 24. The rotation of the crankshaft (not shown) of the engine 18 is transmitted to an intermediate transmission shaft 26 that extends approximately vertically within the goosink 24, and is transmitted at its lower end to a propeller shaft 28 that extends approximately horizontally. 30 to make the hull 10 movable. Reference numeral 32 indicates a two-way motor pump, which is driven by the intermediate transmission shaft 26,
Seawater around the hull lO taken in from the water intake port 34 is pumped into the water supply channel 36 as cooling water, and this cooling water flows into the overshacket 38 formed in the cylinder flock (not shown) of the engine 18. Sent. The cooling water exchanges heat with the engine 18 while passing through the overshacket 38, and is then branched into two routes. The most common route is a route in which the cooling water is guided to a valve chamber 42 having a temperature-sensitive valve 40 made of a thermostat, and is discharged from the valve chamber 42 into the water via a drainage channel 44. On the other hand, the other path consists of a branch passage 46 that branches off immediately before the temperature-sensitive valve 40, and this branch passage 46 is usually made of a flexible material such as a rubber hose.

As shown in detail in FIG. 2, this branch passage 46 reaches an inner wall portion of the bottom cowling 22, where it is connected to a connecting pipe 48 passing through the inner wall portion. This connecting pipe 48 is made strong by being screwed with a mounting nut 50 from the inside of the bottom cowling 22 and by being screwed with a mounting nut 54 from the outside of the bottom cowling 22 via a seal member 52. It is fixed to the bottom cowling 22. A closing valve 56 is provided outside the bottom cowling 22 of the connecting pipe 48, and a hose 58 is connected to the end thereof.

In FIG. 2, reference numeral 60 is an exhaust guide, and the lower end of the bottom cowling 22 is fixed to a leg 62 that is integrally erected on the exhaust guide 60. Reference numeral 64 is an apron that smoothly wraps the lower end of the bottom cowling 22 and the upper outer wall of the casing 24, and 66 is a flange formed on the outer periphery of the exhaust guide rod 0.

According to the embodiment with such a configuration, when it is necessary to wash the ship, the shutoff valve 56 may be opened while the engine 18 is operating, and the hose 58 may be connected to the end of the connecting pipe 48 for washing. At this time, it is preferable that the forward/reverse switching device (not shown) is set to a neutral position and the vessel is kept in a non-navigating state (with no load on the engine 18). Here, the cooling water energized by the rotor pump 32 passes through the rotor shacket 38, so that the hot water (30~
40° C.) and is vigorously supplied to the hose 58 via the branch passage 46 that branches from the position immediately in front of the temperature-sensitive valve 40. Here, in the engine 18, since cooling water is constantly circulating through the overshacket 38, there is no risk of an accident such as overheating.

In this way, there is an advantage that even in the winter, ships can be washed with warm water, and there is no need to use a separate pump or power to pump water.

When the cleaning of the ship is completed, the shutoff valve 56 is closed, and the cooling water is discharged into the sea through the main path via the temperature-sensitive valve 40 and the drainage channel 44. In this embodiment, a branch passage 46 for using cooling water as cleaning water is provided.
The present invention does not necessarily have to be limited to this, but the cooling water after cooling the engine can be branched from the point of view of substantially preventing engine overheating. The water can be used as cleaning water. However, in reality, the temperature-sensitive valve 4
0 serves to open and close the cooling water passage by detecting the temperature of the cooling water, so if the branch passage 46 is branched from the downstream side of the temperature sensing valve 40, for example, if the temperature of the cooling water is extremely high, If the temperature is low, the temperature sensing valve 40 closes its passage, so there is a risk that the cooling water will not flow to the lower casing side of the temperature sensing valve 40. On the other hand, if the cooling water is extremely high temperature (5
Even if the temperature is below 0°C), the high-temperature cooling water is directly guided downstream from the temperature-sensitive valve 40 and used as the high-temperature cooling water or cleaning water, and is not suitable as cleaning water. In some cases.

Therefore, the most preferable embodiment is one in which the temperature-sensitive valve 40 is located at the rear end of the overshack, and the branching point of the branch passage 46 is placed immediately before the temperature-sensitive valve 40.

[Effects] As described above, according to the present invention, there is no need to use a separate pump or the like, and seawater can be pumped with a bucket like in the past.
It has the excellent effect of being able to smoothly clean a ship without requiring a lot of effort and with no space restrictions.
