Description

[Detailed explanation of the idea] This invention relates to a ship equipped with a deck cleaning device.

Conventional ships, especially coal, ore, and other unloading ships, have their decks contaminated by spilled cargo, dust, etc. during cargo handling.

This cleaning requires a lot of work for the crew.

For example, one voyage takes 6 to 8 days.

This invention was made in view of the above situation, and to explain the structure of this invention with reference to the drawings, as shown in Figs. are arranged in the longitudinal direction of the ship, and in the two adjacent nozzles 2, 2 on the axle side and the gunwale side, the shortest injection point m in the linear direction of the nozzle 2 on the gunwale side is set to the axle side nozzle 2. This is a ship equipped with a deck cleaning device in which the distance l between the two nozzles 2.2 is set so that the firing range S to the side of the nozzle is greater than that of the nozzle 2.

In the figure, 6 indicates a hatch, 7 indicates piping, and 8 indicates the ship body.

Further, the piping 7 of the nozzle 2 may be a low pressure water such as a fire extinguishing line, and in addition to automatic swinging in the horizontal and vertical directions, it can also be switched manually.

To explain this in detail, first, the structure of one embodiment will be explained. Since the structure has many power transmission mechanisms, the structure will become clear by explaining the power transmission path, so it will be based on the power transmission path. I will explain.

In FIG. 5, pressurized water is introduced from the inlet 9 of the casing 8, rotates the turbine 11, and is discharged from the nozzle 2 (FIG. 4).

In this case a valve 10 may be used to reduce the water pressure on the turbine 11.

The turbine 11 rotates its shaft 12, shaft 13, and a worm 14 provided thereon, and then a worm wheel 15,
The shaft 16, the worm 17 provided on the shaft 16, the worm wheel 18 (Figs. 5 and 6), are transmitted in this order to the shaft 19 (hereinafter shown in Fig. 6), which is provided on the shaft 19. The armament 20 (Figures 6 and 7) is turned, and the gear 21 (hereinafter referred to as Figure 7) that meshes with it is turned.

The gear 21 has an arm 22, which causes the gear 23 to reciprocate and then sequentially reciprocates the gears 24 and 25.

In this specification, the above-mentioned "swinging" has the same meaning as "reciprocating rotation".

Next, the gear 25 and the main shaft 26 (FIGS. 7 and 5) are spline-coupled, so that the main shaft 26 rotates back and forth.

The main shaft 26 reciprocates a shaft 28 via a coupling 27, and then a nozzle body 33 (FIG. 8) from within the main pipe 29 (FIG. 4) via a key 32.

Note that the nozzle body 33 is rotatable about the bracket 34 by a thrust bearing 35.

Next, the rotation of the shirt T-19 (FIGS. 5 and 6) rotates the worm 36, which rotates the worm 39 via the worm wheel 37 and its shaft 38 that engages with the worm wheel 37.

The worm 39 then rotates the worm wheel 40 (which is the back of the worm gear 39 in FIG. 6 and does not appear in the figure), and the worm wheel 40 rotates its shaft 41. Turning gear 42, which turns gear 43.

A rotary cam 44 is fixed to the gear 43, and the cam 44 makes a detour.

The cam 44 has an endless cam groove 45,
A follower 46 is engaged with this cam groove 45, so that the follower 46 moves up and down as the rotary cam 44 rotates.

The follower 46 is attached to the main shaft 26 such that the main shaft 26 is rotatable.

Further, the follower 46 has a holding portion 4γ, and the holding portion 47 is
It engages with a vertical guide 48 fixed to the casing 8 so as to be movable in the vertical direction, so that the follower 46 moves the main shaft 26 vertically without rotating.

Further, the main shaft 26 is reciprocated by the gear 25 (FIG. 7) provided thereon as described above, and the gear 25 and the main shaft 2
6 is connected to the spline 50, so the main shaft 26 is
Performs reciprocating rotation and vertical movement.

In addition, the main shaft 26 vertically moves a center shaft 52 having a rack 51 via a shaft 28, and a rank gear 5 that meshes with the rack 51.
Rotate 2 back and forth.

This reciprocating rotation turns a shaft 53 and a gear 54 fixed to the same gear 52, thereby turning a gear 55.

Since this gear 55 is fixed to the nozzle rotor 56, the nozzle 2 provided on the nozzle rotor 56 swings.

This oscillation is changed by the groove 45 of the rotary cam.

Therefore, the nozzle 2 performs a swinging movement around the nozzle holder 57.

In this way, the nozzle 2 swings in the horizontal direction (reciprocating rotation) and also swings in the vertical direction.

In FIG. 7, by rotating the clutch 58, the lever 59 that is threaded therewith moves in the direction of arrow A59, and by rotating the support base 60, the gears 24 and 23 are separated, and the nozzle 2 The lateral (horizontal) direction can be rotated manually.

In addition, in order to manually swing the nozzle 2 in the vertical direction, the worm wheel 40 and shaft 41 shown in FIG. 5 can be insulated by disengaging the clutch 61 shown in FIG.
In this way, the vertical movement of the nozzle 2 can be performed manually.

Note that 62 in FIG. 6 also indicates a clutch.

Next, when cleaning the deck 1, water is sprayed sequentially from the nozzle 2 near the shaft end 3, and as shown in Figures 2 and 3, water is discharged while swinging the nozzle 2 in the horizontal and vertical directions. The cleaning part is the next step, the shortest injection point m of nozzle 2 on the line side
If the water exceeds the limit, the water discharge is stopped, and then the next stage nozzle 2
Clean the area one by one by spraying water on it.

This invention is constructed as described above, and the nozzle 2 on the line side,
The distance l between the two nozzles 2, 2 is set so that the firing range S of the nozzle 2 on the shaft tip side toward the line side exceeds the shortest injection point m in the line direction.
By operating the nozzle 2 sequentially from the shaft tip side to the line side, dust, spilled cargo, etc. on the deck 1 can be sent to the line part and cleaned.

This cleaning is effective if carried out while the ship is underway because the wind direction and water discharge direction match.

In this way, the ship equipped with the deck cleaning device of this invention can very easily clean the deck without causing a great deal of labor to the crew as described in the conventional example.
