Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water surface cleaning ship for collecting dust floating on the surface of water such as river ports and dams, and more particularly to a narrow water surface such as a shore or a pier. In this case, a dust collecting effect is exhibited.

[0002]

2. Description of the Related Art Conventionally, when picking up dust floating on the surface of water, generally, the catamaran generally sails for natural influx of dust, or a small amount of mechanical power and a large amount of human power are used to collect dust. It was customary to do so.

[0003]

In recent years, the amount of refuse discharged through rivers and the like has been steadily increasing, and various water surface cleaning boats have been devised for the purpose of collecting the floating refuse. Scattered garbage has characteristics such as being separated by external forces, so that dust collection work is extremely difficult, especially in shallow water areas such as shores and narrow water surfaces such as under piers, it is difficult for intrusion of heavy equipment ships, etc. The situation is still dependent on manual work using small boats.

[0004] The present invention solves these problems, and can collect dust floating in general, and can smoothly collect dust even in a shallow water area such as a shore or a narrow water surface such as under a pier, which was conventionally difficult. The purpose is to provide a cleaning boat.

[0005]

In order to achieve the above-mentioned object, in a water surface cleaning boat according to the present invention, a dust basket that can be arbitrarily protruded is disposed at a bow portion, and its height, front and rear positions, and elevation are adjusted. The attitude is controlled according to the dust collection operation, and the bottom and side surfaces of the front of the dust collection basket are appropriately enclosed to form a water channel, and the configuration near the water channel front end, which will be described later, is effective for inflow of dust that floats. A plurality of fountain nozzles crossing below the water surface are provided in the waterway at an appropriate distance from the front end of the waterway, and the water is jetted rearward with an appropriate depression angle, and the pressure water to be jetted is supplied from inside the ship. Things.

In constructing the vicinity of the front end of the water channel, the bottom surface is surrounded by an appropriate inclination angle (A) and the water level (H) which is necessary for inflow of garbage and substantially minimum water level (H) is required. And a water flow guide plate protruding with an appropriate depression angle (B) and overhang at the front end thereof, and the joint part is made streamlined, and a substantially laminar surface water flow is introduced from the free water surface to introduce garbage. Plan.

In addition, the above-mentioned dust collecting basket is always drained and stored between the twin hulls so as not to hinder the normal navigation of the ship, and when starting dust collecting work, it is operated by operations such as up and down, raising and lowering, and sliding. It is better to control the protrusion.

Further, when cleaning the water surface at the shore or under the pier, it is a matter of course that a boat with a shallow draft is used. However, together with the main dimensions of the dust collecting basket, the inclination angle (A) of the water channel bottom surface It is preferable to properly consider the depression angle of the fountain flow, the depression angle (B) of the water flow guide plate provided at the front end of the water channel, and the overhang.

[0009]

In the water surface cleaning boat constructed as described above,
At the beginning, when the ship is equipped with a dust collection basket, first, the guide roller provided at the rear of the dust collection basket is matched with the basket guide rail on the basket support base leg, and then it depends on the gravity at the front of the dust collection basket. The basket storage winch provided on the upper part of the basket support table is rolled up and the basket drawer winch is simultaneously unwound and the dust collection basket is stored in the basket support table, and the basket provided on the deck of the twin body. The upper and lower hydraulic cylinders of the support base are operated to store the basket together with the basket support base at an appropriate height above the water surface.

When the ship starts dust collection work, the dust collection basket is arbitrarily protruded toward the bow by a process reverse to the above-described storing step, and the height of the basket is adjusted by a cage support base vertical hydraulic cylinder. Use the storage winch and the basket drawout winch to adjust the front and rear and the elevation, and maintain an appropriate water level at the front end of the dust collection basket.

Here, if the pressure water is supplied from the inside of the ship to the fountain nozzle in the water channel formed at the front of the dust collecting basket, an appropriate wake effect caused by the fountain flow causes a torrent in the water channel. Then, the water level between the front end of the water channel and the vicinity of the fountain nozzle drops, so that the surface water flow is introduced from the free water surface and floating dust flows in.

Further, in the vicinity of the front end of the water channel, an appropriate inclination angle (A) is provided on the bottom surface, and the front end has an appropriate depression angle (B) and overhang allowance through a streamlined joint. Since the water flow guide plate is provided, the surface water flow flowing from the free water surface into the water channel can be introduced as a substantially laminar flow, and at the same time, the water flow layer passing through the streamlined joint can be made denser. The viscous nature of the water flow promotes the development of surface water flow on the adjacent free water surface.

[0017]

According to the present invention having the above structure, the following effects can be obtained.

The use of the basket support makes it easy to control the up, down, front, and back of the dust collection basket, and raise and lower the dust collection basket.

The use of the cage support allows the dust collection basket to be easily attached to and detached from the front of the bow. Therefore, when the dust collection operation is completed, the spare collection can be easily performed using the slope such as an incline or a shore. Can be exchanged for a dust basket.

Further, since a water channel is provided at the front of the dust collecting basket, the weight required for the control operation can be skillfully added to the dust collecting basket. Sources can also be saved.

Further, by employing the dust collecting basket control device, the water level of the dust inlet provided at the front end of the water passage of the dust collecting basket can be easily minimized, and the water flow guide plate protrudingly provided at the front end of the water passage can be provided. However, since the amount of water that floats from deep underwater is reduced, the amount of waste water that flows in with dust during dust collection work can be easily reduced, and the dust collection efficiency can be increased.

Further, the refuse flowing into the above-mentioned water channel gathers together with the torrent caused by the fountain nozzle and sequentially accumulates at the rear part of the dust collecting basket. it can.

In addition, according to the present invention, the dust collecting basket control device is constituted by the basket support table, and the dust collecting device can be constituted by providing a water channel and a power in the dust collecting basket. The construction work of the water cleaning vessel can be divided into separate tasks, and the advantage of shortening the construction period can be obtained.
