The driving part 120 is a caterpillar that moves in a caterpillar, and unlike the illustrated example, a structure of driving by rotation of the wheel may be applied.

The boom 112 mounted through the driving frame 125 is rotatably coupled to the driving frame and extends the proximal boom 112a and the stop boom 112b rotatably coupled to the end of the proximal boom 112a. , It is made of a terminal boom 112c rotatably coupled to the end of the middle boom 112b.

In addition, between the driving frame 125 and the tip boom 112a, the tip boom 112a and the stop boom 112b, and the stop boom 112b and the end boom 112c, respectively, the first to third cylinders 114a To 114c) is mounted to enable adjustment of the position of the end boom 112c.

The chamber 130 is formed in the shape of a quadrangular enclosure having a washing space 132 with an open bottom, and is coupled to the end boom 112c.

The washing cap 140 is formed in a semi-circular shape so that the chamber 130 has an air filling chamber 142 with a lower opening inside the washing space.

The washing cap 140 can suppress immersion by air supplied to the air filling chamber 142 inside when the chamber 130 performs a purification operation on the underwater bottom surface, thereby improving washing efficiency by washing water. have.

In addition, when the chamber 130 performs the purifying operation on the underwater floor, the washing cap 140 forms a buoyancy space by the air supplied to the air filling chamber 142 inside, so that the working body 110 is underwater. It also provides a function to suppress conduction by compensating for the direction of the boom 112 according to the unfolding and descent of the boom 112 in a barge (not shown), for example, on a floating work ship.

In the illustrated example, one washing cap 140 is applied to the washing space 132 inside the chamber 130, and a plurality of washing caps 140 may be formed to be spaced apart from each other, unlike the illustrated example. .

The washing water supply unit 150 is capable of supplying washing water into the air filling chamber 142 of the washing cap 140.

The washing water supply unit 150 includes a washing water spray nozzle 151, a washing water supply pipe 153, and a first pump (P1) 155.

The washing water injection nozzles 151 are arranged to be spaced apart from each other along the longitudinal direction in the air filling chamber 142 of the washing cap 140 and connected to the washing water supply pipe 153.

The washing water supply pipe 153 is connected to the washing water injection nozzle 151 and extends out of the chamber 130.

The first pump (P1) 155 pumps water through one end of the washing water supply pipe 153 to supply high-pressure washing water to the washing water spray nozzle 151 connected to the other end of the washing water supply pipe 153.

Here, the other end of the washing water supply pipe 153 may be installed to supply water in the water to be purified or water stored in a separate water storage tank.

The air supply unit 160 supplies air to the air filling chamber 142 inside the washing cap 140 so that water is not filled inside the washing cap 140 when the chamber 130 performs purification on the underwater bottom surface. It supports to form an empty air filling chamber without being empty.

The air supply unit 160 includes an air supply nozzle 161, an air supply pipe 163, and an air supply 165.

The air supply nozzle 161 is installed to discharge the air supplied into the air filling chamber 142 inside the washing cap 140.

In addition, the air supply nozzle 161 may be installed to extend shorter from the blocked ceiling surface of the washing cap 140 than the washing water spray nozzle 151 or not to protrude downward from the ceiling surface.

In this case, the air filling chamber 142 that is not submerged by air supplied from the air supply nozzle 161 is secured, and the washing efficiency of the washing water for the object to be cleaned existing in the air filling chamber 142 can be improved.

The air supply pipe 163 is connected to the air supply nozzle 161 and extends out of the chamber 130.

The air supply 165 may suck air and supply air to the air supply nozzle 161 through the air supply pipe 163, and an air compressor that compresses and supplies air may be applied.

The contaminant separation unit 170 separates contaminants by rotational contact in the washing space 132 inside the chamber 130.

The contaminant separation unit 170 is rotated by the driving unit and includes a brush 172 for washing gravel or floating contaminants on the floor.

The brush 172 is provided with brushes for washing on the outer circumferential surface of the rotating shaft rotated by the driving source.

The driving source of the brush 172 may be a hydraulic motor or an air motor.

In addition, a rotating cutter (not shown) may be installed on the outer circumferential surface to rotate and cut contaminants in the washing space 132 of the chamber 130.

In addition, a rotor (not shown) installed on the outer circumferential surface of the rotating shaft may be installed in the washing space 132 of the chamber 130. Here, the rotor may be formed by installing an excavating blade for excavating the bottom surface on the outer circumferential surface of the rotating shaft.

The contaminant sending unit 180 is coupled to the chamber 130 to discharge contaminants removed through the contaminant cleaning process from the cleaning space 132 inside the chamber 130 to the outside of the chamber 130.

The contaminant delivery unit 180 is coupled to the discharge pipe 183 in communication with the washing space 132 of the chamber 130 outside the chamber 130 and the discharge pipe 183 coupled to the discharge pipe 183 to remove the contaminants removed in the chamber 130. It is provided with a second pump (P2) (185) for pumping.

Here, the first and second pumps 165, 185, the air supply 165, the brush 172, the driving unit and the manipulator (not shown) for controlling their operation are the driving frame 125 of the working body 110 It is desirable to be installed on.

The apparatus for removing contaminants on the bottom surface of the water to be purified is a chamber, the sea, a lake, a river, etc., in a state where the working body 110 is mounted to work on a work boat floating in the water, for example, a barge (not shown). The first and second pumps 165, 185, air supply 165, and brush 172 are operated by controlling the manipulator while seated on the bottom of the washing water, high-pressure air and brush It can be separated through the rotation of 172 and sent through the discharge pipe 183.

The operation of the apparatus for removing contaminants at the bottom of the water body to be purified is as follows.

First, the chamber 130 is seated in close contact with the floor of the water body to be washed, and then the air is supplied from the air supply 165 through the air supply nozzle 161 while the first pump 155 is introduced into the washing cap 140. The high-pressure water is supplied through the washing water injection nozzle 151 by the operation of the. In addition, the brush 172 installed in the chamber 130 is rotated to float contaminants. In this process, the chin cap 140 forms an air filling chamber 142 that is not filled with water by the supplied air, and in this process, the washing efficiency of the washing water sprayed through the washing water spray nozzle 151 is further improved. . In addition, the brush 172 is in parallel with the action of washing the gravel and stones on the lower surface.

Through this process, contaminants floating in the washing space 132 of the chamber 130 are pumped by the second pump 185 through the discharge pipe 183, and the pumped water is disposed outside the treatment tank (not shown). ).

This operation can be performed while moving the work body 110 and the chamber 130.

According to the apparatus for removing contaminants at the bottom of the water body to be purified as described above, an air filling chamber filled with air supplied to the washing cap in the chamber is provided to provide an advantage of further improving washing efficiency.
