The present invention relates to an underwater truck that collects sludge while reciprocating by traction of a wire rope connected to a drive motor along a rail installed at the bottom of the sedimentation basin. More specifically, the lower part of the wheel transports the reciprocation along the rail of the sedimentation basin. The upper portion is an underwater bogie consisting of a seesaw that performs seesaw movement with a triangular post as a central axis, an L-shaped shear scraper and a rear end scraper rotating around a hinge at both ends of the subsea carriage, and the hinged shear A front link bar and a rear link bar configured to be coupled by a link axis at the other end of the scraper and the rear end scraper to link the body toward the body center of the water cart, and the front link bar and the rear link bar are formed on both sides of the seesaw. Operation of scraper characterized by being configured to engage in link movement by connecting shaft It relates to an underwater bogie for sludge collection which can be easily adjusted.

In general, in a sedimentation tank or agglomeration tank such as a water purification plant or a water intake plant, as the time passes, various suspended solids sink to the bottom of the sedimentation tank due to the specific gravity difference or are forced to a bottom surface of the sedimentation tank by coagulant or flocculant. Sludge is formed.

Leaving these sludges for a long time reduces the flow rate of flowing water, accelerating the rate of continuous sludge settling, and the precipitated solidified sludge not only promotes contamination of the water flowing by the contaminants in the sludge itself, but also causes odors due to waste sludge. It will adversely affect the surrounding environment.

Various means have been devised to remove the sludge that has sunk in the settling tank or the coagulation tank as described above.

1 is a state diagram showing a conventional truck for collecting sludge, the operation scraper 104 is mounted on the lower side in the front side of the water cart 100, the guide roller 112 is installed on the upper by the operating hinge 106 An actuating post 102 installed angularly, a driven scraper 105 disposed at a lower side thereof, and a driven post 103 installed angularly by a driven hinge 107 and the subsea vehicle 100. The link 110 is installed on the frame 101 by pins 109 of the fixed support plate 108, and is connected to both ends of the link 110 to connect the operation post 102 and the driven post 103. The rod 111 is configured to be discharged separately by reciprocating the sludge accumulated on the bottom surface of the structure to the collecting groove.

However, the sludge collection subwater truck 100 having the above configuration removes the sludge accumulated unevenly because the operating range of the operating scraper 104 for contacting and removing the sludge deposited on the bottom surface is fixed. It is not easy to structure.

Particularly, in the case of sludge stacked in contact with the wall surface, when the wall surface is not perpendicular to the sea surface due to the condition of the site, the water cart 100 is inclined obliquely by slanted or irregularly deposited sludge. It is often difficult to remove only the working scraper 104 of 100), so that it is often necessary to remove the sludge accumulated in the wall directly.

In addition, in order to supplement the operating scraper 104 having a limited operating range, additionally, a complex device such as a guide roller 112 is required to be installed together with the guide guide 113, so that the submersible truck 100 with additional manufacturing cost is provided. The disadvantage of heavy weight is also pointed out.

The present invention has been made to solve the above problems, by adjusting the length of the link bar connected to the front and rear scrapers of the sub-car, the angle of the front and rear scrapers in contact with the wall surface to the environment of the work site The purpose is to be able to adjust properly to fit, and the simple structure can be expected to reduce the production cost.
