Abstract

PURPOSE:To contrive the quick collection of refuse under water by equipping a refuse suction means, a filter means, a drain means and a power supply means in a ship provided with the outboard motor of a radio control and a float. CONSTITUTION:On a hull 1 which is in the form of connecting two stainless steel made enclosed type floats 11, the water suction opening 21 of a suction pump 2 is faced toward water surface to arrange under the water surface between the floats 11. The water suction opening 21 is equipped so as to semicircularly cover the rearward thereof with the use of a suction cover 22 and the refuse floating on the front water surface is sucked with water. The refuse and water sucked with the use of the pump 2 are introduced into a filter 4 through a suction hose 3 to comb off the refuse guided by the hose 3 by the use of the filter. Water passing the filter passes drain piping of the lower part of the filter 4 to drain from a drain opening of the lower part of the water surface.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates in particular to an apparatus for collecting debris from the surface of a spent fuel storage boule in a nuclear power plant.

[Prior Art] Spent fuel burnt in a nuclear reactor is stored and cooled in a spent fuel boule. Here, even if the spent fuel pool is well-managed, small particles (cotton dust, etc.) may fall, and in order to remove these small particles,
Manual collection may be required.

[Problems to be Solved by the Invention] The present invention is capable of moving close to garbage even in places where remote control is required due to harmful radioactivity, such as cooling ponds and storage pools at nuclear power plants. The purpose is to obtain a device capable of collecting debris on the water surface as quickly as possible.

[Means for Solving the Problems] In the self-propelled skimmer device according to the present invention, a radio-controlled outboard motor is used in the skimmer device for skimming cooling oil at a nuclear power plant or debris that has fallen onto the water surface of a storage pool. and a closed-type float, a suction means for suctioning dirt together with the water below the water surface, a filter means for scooping up the dirt that is sucked together with the raw water, and a drainage system for discharging the water filtered by the filter means. and a power supply means for supplying power to the outboard motor and equipment mounted on the hull.

[Function] In the present invention, a hull equipped with a radio-controlled outboard motor and a sealed float is provided with a suction means for sucking up dirt along with the water below the water surface, and a filter means for scooping up the dirt sucked together with the raw water. , a drainage means for discharging the water filtered by the filter means, and a power supply means for supplying V3 power to the outboard motor and on-board equipment on the hull, so it can be used for cooling oil and storage at nuclear power plants. Due to harmful radioactivity in swimming pools, etc., it is possible to move to the vicinity of the garbage by remote control or wireless remote control even if it is necessary, and it is necessary to collect garbage on the water surface as quickly as possible. can.

In other words, with wire control, the wires sometimes became an obstacle to operation, but the present invention is equipped with a radio-controlled outboard motor and power supply means, so it can propel itself independently.
You can easily move to the garbage without any obstacles.

Additionally, because the hull is equipped with a sealed float, the equipment will not sink into nuclear power cooling oil or storage pools, which are difficult to recover from the bottom of the water.

In addition, it is also possible to discharge the drainage water from the drainage means into the water, in which case the water surface will not ripple due to the drainage flow.
The operation of the device becomes easier.

[Embodiment] FIG. 1 is a top view showing the configuration of an embodiment of the present invention, FIG. 2 is a front view of FIG. 1, and FIG. 3 is a cross-sectional view taken along the line AA in FIG. 1.

As shown in the figure, two stainless steel plates (for example, 5LIS
There is a hull (1) in the shape of a closed type float (11) made by A.304) connected to it. Float (11) in front of the hull (1)
A suction pump (2) is disposed below the water surface between the two, with its water intake port (21) facing the water surface. A suction cover (22) is attached to the rear of the water suction port (21) in a semicircular manner so as to suck up debris floating on the water surface in front of the water inlet (21) along with the water.

Dust and water sucked by the suction pump (2) are led to the mA device (4) via the suction hose (3).

The mA device (4) includes a filter (41) and a filter holder (4).
2), filter receiver (43), filter, i (44),
It is composed of Patsukin (45).

The dust led by the suction hose (3) is passed through the filter (41).
), the water that has passed through the filter (4I) passes through the drain pipe (5) at the bottom of the filter (4) and is further discharged from the drain port (51) at the bottom of the water surface. The filter (41) is replaceable in a cartridge style.

Movement of the equipment on the wood grain side is carried out by radio controlling the screws of the two outboard motors (6).

A battery (7) and a receiver (not shown) for powering the suction pump (2) and the outboard motor (6) are housed in a battery housing (71) at the bottom of the filter (4).

The running balance is achieved by a balancer (52) installed at the bottom of the hull (1) and the drainage pipe (5).

The upper part of the hull (1) is equipped with a ring (8) made of a thin elastic metal plate formed into a ring shape and pasted with a rubber plate (81). This ring (8) serves as an interference and cushion to the pool wall surface of the hull (1).

As mentioned above, the self-propelled skimmer device using the wood flow side has two radio-controlled outboard motors (6) and power supply to them, although the wires sometimes interfere with operation with wire control. Since it is equipped with a battery (7), it is self-propelled and can be easily moved to the garbage area.
Even in places where remote control is required due to harmful radioactivity such as cooling oil and storage pools at nuclear power plants, it is important to move to the vicinity of the garbage and remove the garbage on the water surface as quickly as possible. It can be recovered.

In addition, since the hull (1) is equipped with a sealed float (11), the equipment will not sink into nuclear power cooling oil or storage pools that are difficult to recover from the bottom of the water. Since it is installed underwater, the water surface does not ripple due to the drainage flow, making it easier to operate the device.

Furthermore, in order to reduce interference with other equipment and the wall of the wall,
The ring (8) is attached.

Dust sucked in through the water intake port (21) is stored in the filter (4). The filter (41) of the filter (4) can be replaced as a cartridge and can be incinerated.

Also, if it is not needed, it can be taken out of the pool and stored on the floor.

[Effects of the Invention] As explained above, the present invention has a hull equipped with a radio-controlled outboard motor and a closed type float, and a suction means for sucking up dust along with trees under the water surface, and dust that is sucked up along with raw water. A nuclear power plant is equipped with a filter means for scooping up wood, a drainage means for discharging the wood filtered by the filter means, and a power supply means for supplying power to the outboard motor and tower 1TIIi equipment on the hull. Even in places where remote control is required due to harmful radioactivity, such as in cooling oil or storage pools, wireless remote control can be used to move to the vicinity of the debris, and remove debris on the water surface as quickly as possible. can be recovered.

In other words, with wire control, the wire could sometimes become an obstacle to operation, but since the present invention is equipped with a radio-controlled outboard motor and a power supply mechanism, it can run independently,
You can easily move to the garbage without any obstacles.

Additionally, because the hull is equipped with a sealed float, the equipment will not sink into nuclear power cooling oil or storage pools, which are difficult to recover from the bottom of the water.

Note that when the waste water is discharged into the water, the water surface does not ripple due to the flow of the waste water, making it easier to operate the device.
