Abstract

PURPOSE:To improve the extent of refuse collection efficiency as well as to expand an operating range, by installing an opening, taking in water from the outboard, in the bow, while installing a duct with a built-in propeller in the stern, and installing a guide through-hole between a hold at the midship part and the duct. CONSTITUTION:In the bow, there is provided with an opening 1 which takes in water from the outboard, and at the midship, a twin-shell body 2 is connected thereto at a bottom plate 3, forming a hold 4. In the opening 1, there are pro vided with two gate doors 8 and 8 in watertight structure. These doors 8 are attached to a tip of the twin-shell body 2 with hinges, and at the refuse collec tion, they are opened as wide as more than 90 deg., functioning as a straightening vane guiding the refuse flowing in. At the time of forward movement of the ship, water from the outboard passes through the opening 1 of the bow and enters the inside of the hold 4 in which the refuse is collected in a bucket 11. Water passing through this bucket 11 is discharged outboard after passing through a duct 6 with a built-in propeller 5, from a guide through-hole 7.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application on 111] The present invention relates to a work boat that can be used for collecting garbage floating on the water surface and also for other general work.

[Prior art] Ships that collect garbage floating on the water surface are roughly divided into belt conveyor type, defroster type, and packet type.The belt conveyor type, one type, and the one type baffler type have mechanical parts. Due to the fact that many maintenance inspections are cumbersome, the current
The 70 star single type is the mainstream.

This f) [1 star H type ship - example v810~12
As shown in the figures, this ship has a twin fuselage 21 connected to the center of the hull by a bottom 22, while water enters the bow from outside the ship (120 steps). A hold 23 is formed, and a large number of discs 24, 24 .・
. . 24 arranged in parallel are provided.

This O-tar 25 is an independent i-worker! 1 (not shown), and the bottom of the hold 23 has a plurality of drainage holes 26, 26. ...26 has been cleared. In addition, one J-plane 28 for driving and rotating the propeller 21 is installed at the rear of the twin fuselage 21, and a wheelhouse 29 is installed on the rear upper deck to straddle the twin fuselage 21. . The principle of the 1 star 6 type on the differential is to rotate the rotor 25 at a speed of
] It uses the viscosity of water to generate water flow. Therefore, in order to demonstrate this function, the bottom 22
It is necessary to narrow the gap between the opening and the 0-tar, so the bottom 22a of the opening is raised.

[Problems to be Solved by the Invention] In the case of this one-type defroster, as mentioned above, the gap between the rotors must be reduced. As a result, large floating objects such as lumber could not be collected. In addition, since the cleaning capacity is determined by the 1-ter, it is necessary to install a gate or flow guide plate on the bow.
Even if the cleaning speed was improved, the cleaning speed could not be improved. Additionally, a new prime mover was required to rotate the rotor.

[Means for Solving the Problems 1] The present invention has been made to solve these problems, and it is applicable to garbage collection equipment ([I-tar, bell l-
It is based on the idea that the ship's transport mechanism is used to collect garbage without any special equipment such as a conveyor or bag.

In other words, in the present invention, an opening is provided in the hull for introducing water from the outside, and the center part of the hull is made up of two twin fuselages connected at the bottom, thereby forming a hold, and connecting the J3 to the stern. There is also a work boat equipped with a duct with a built-in propeller and a through hole installed between the hold and the duct.

A pipe installed at the bow of the ship is for garbage collection and introduces surface water to be cleaned from outside the ship. This opening should be large enough to span the entire front surface of the hold unless it has a special purpose. In order to reduce propulsion resistance during general navigation, it is preferable to provide a gate in the internuclear space. When open, this opening should form a convex forward side of the ship. However, this type of ship is not meant to sail at high speed, so (b) From the point of view of using the ship for multiple purposes, it is desirable that the gates form a watertight condition when opened.Two gates should be installed symmetrically on the left and right sides. [1-1] If you turn to the right, the gate will act as a flow guide plate when opened, expanding the opening for cleaning.

If there is only one gate, it may be lifted up to open it, or it may be tilted forward or backward so that it opens.

The flow guide plate can also be installed separately.

In the center of the hull, the twin fuselage cannot be connected at the bottom.
This creates a hold for garbage collection. From the point of view of introducing water flow, it is preferable to raise the front part of the bottom of the ship, that is, the upper surface near the fJII 0 part, to form a so-called raised floor.

A bucket 1- for collecting garbage is installed in the hold.

In addition to the hull, this packet's tiers, side walls, and bottom are all made of a material capable of filtering out debris, such as a grid, net, or perforated plate. The front of the packet should be hinged so that it opens forward when collecting garbage, and on the other hand, when lifting the packet containing garbage from a ship, it is best to raise it up to prevent the garbage from falling. Position the packet and also
Protrusions, protrusions, spacers, etc. are provided as appropriate on the packet side or the hold side in order to maintain a constant distance between the packet and the wall and bottom of the hold.

A duct with a built-in propeller is installed at the stern, and a through hole is installed between the hold and the duct. This duct regulates the water flow, and the 1 propeller sucks water from the hold, allowing the propeller to not only propel the ship but also strengthen the water flow inside the hold for garbage collection. In order to carry out general navigation efficiently, it is better to provide a separate water intake in the duct and use it during general navigation. The hold side opening of the conduction hole is usually installed at the rear of the hold), but
It can also be installed on the side or the rear of the bottom if necessary.

It is preferable that a grid or the like be provided in this L1 portion with a step number. The water intake port may be provided on either the side or the bottom of the duct. A shutter is provided at the conduction hole and water intake [-1] so that the water intake to the propeller can be switched. It is preferable that each shutter can be set to be fully open or fully open, or to be able to adjust the opening degree as appropriate. Both the conduction hole and the water intake are 1
Since it is not necessary to provide an Mji-C, it is convenient to have one shutter that can be used for both purposes.

If the upper part of the hold, for example, is equipped with a garbage cover similar to that used in MSI vehicles on land, it is possible to lengthen the length of each trip and efficiently collect garbage.

A ship is equipped with the necessary equipment for navigating the ship, such as its main engine, rudder, wheelhouse, etc.6.

The vessel of the invention can also be used for purposes other than garbage collection. For example, an oil recovery device such as a cyclone can be installed in the hold instead of a packet, and the vessel can be used as a surface oil recovery vessel. The water flow in the hold is 1
Since it is accelerated at zero angle, it has the advantage of high oil recovery capacity. It is also possible to install an oil fence inside the small ship and use it as an oil fence deployment vessel. By opening the gate between the bows and the bow, the water level inside the hold becomes the same level as outside the vessel, making it easier to deploy and store the oil fence compared to other deployment vessels (2
Ru. Furthermore, by making the gates, shutters of the passage holes, etc. watertight, or by installing temporary gratings etc. on the hold (general cargo or personnel can also be loaded on the hold and used as a general transportation ship) It is also possible to write

[Action 1 Floating on the water surface from L1 of part M of the ship? The waste is introduced together with water, and the hold part collects and covers the waste. Water taken into the hold is sucked by the propeller through the through hole and drained, allowing continuous introduction of water into the hold from outside the vessel.

[Example] A plan view of a ship according to an embodiment of the present invention is shown in FIG. 1, a side view is shown in FIG. 2, a rear view is shown in FIG. A plan view of the parts is shown in Fig. 4.

As shown in Figures 1 and 2, an opening 1 for introducing water from outside the ship is installed in the bow, and a twin fuselage 2 is connected at the bottom 3 in the center of the ship, thereby forming a hold 4. There is. A duct 6 with a built-in propeller 5 is installed at the stern.
A conductive hole 7 is provided between the hold 4 and the duct 6.

Two gates 8, 8 made of water IBIM are provided in the opening 1. This gate fj? ' 8 L; L, shown in Figure 1 J
A hinge is attached to the tip of the twin fuselage 2, and when closed, both come together to form a semicircle. Both gates 8, 8
are opened and closed by the operation of hydraulic cylinders 9, 9 powered by the main engine 13 installed at the tip of the twin fuselage 2.2. This operation is performed by remote control from the wheelhouse 18. This bar rR, 8 should be tilted at 90 degrees or more when collecting garbage.
It functions as a flow guide plate that guides inflowing debris.

A slope 10 is formed on the opening side of the ship bottom 3.

A box-shaped bucket 11 covered with a net is installed inside the hold 4. The front side 12 of the packet 11 is hinged (

The rear part of the hull is a monohull type, and the main T113 is installed inside (
A duct 6 and a conduction hole 7 are formed. As shown in FIG. 2, a water intake port 14 is provided at the bottom of the duct 1-6, and a switching flap 15 is provided inside the duct 6 as a shutter. By rotating this switching flap 15, the conduction hole 7 or the water intake port 14 can be closed.

The flap 15 is remotely controlled from the wheelhouse 18 and rotated by a hydraulic cylinder (not shown) powered by the main engine 13. It is also possible to stop the flap 15 in an intermediate position. As shown in FIG. 4, the entrance 16 of the through hole 7 is in the form of a tunnel, into which a grid is fitted.

A rudder plate 17 is attached to the rear of the propeller 5.

As for the ship maneuvering method, during general navigation, the gate (3) is closed using the hydraulic cylinder 9, and the opening 7 is closed by rotating the sea urchin switching flap 15 (shown in FIG. 6).

As the bella 5 rotates, the water is taken in [water taken in from 114 is behind the river, and the uC boat is in front! 7. When the ship approaches, the clutch that is built into the main engine 13 is used to reverse the rotation of the reverse rotation.

~ 11 raises the front 12 and returns to the 'C box shape. When the ship arrives at the base, the packet can be lifted up with a crane or the like and unloaded.

Bouts I- can also be divided depending on the size of the ship, etc.

Examples of using two packets are shown in FIGS. 8 and 9. First, as shown in FIG. 8, the front surface 12a of the packet lla on the front side of the hold 4 is not tilted forward, and the rear surface is folded inward. Next, the packet 11b is installed on the rear side of the hold 4, and its front side 121) is folded forward so that it rests on the folded rear side -1 of the front packet lla. As shown in FIG. 8 1, if the bottom of the rear bucket l-11b is made slightly higher so that the front surface 12b is flat or slightly downward, it becomes easier for dirt to move rearward smoothly. As shown in FIG. 8, when a cleaning cruise is carried out with the packets 11a and 11b installed, garbage collects behind the packets. When the packet 11b is full of garbage, as shown in FIG.
The cleaning cruise ends when 1a is also full of trash.

[Effects of the invention in Song Dynasty] The ship of the present invention has good garbage collection efficiency because it utilizes forced water flow using a 7-day bell in addition to the natural water flow caused by sailing. Large floating objects such as lumber can be collected from a wide area.The collection mechanism is simple and easy to maintain and inspect.

Also, if you want to collect only floating objects, put them on the bottom of the ship! [1] There are almost no protruding objects such as bellows, and the change in water during collection work is small, so the work range is expanded compared to the current ship.

Mugt Ming ships are versatile and can be used for multiple purposes.
