A lynch winding a rope by a motor operation can be installed on both ends of the horizontal bar of the sludge deposit removal method while the rope of the lynch pulls the brush in the brush cap with the motor mounted thereon, thereby enabling the reciprocating motion to left and right.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a method for removing sediments from a sludge,

The present invention relates to a horizontal bar type horizontal sludge removal apparatus and a sludge removal method using the same, and more particularly, to a sludge removal method using an underwater floor Sludge layer stacked on the surface of the sludge sludge layer is swept away as if the large area is swept away by reciprocating brush left and right.

In the rivers, artificial lakes and rivers, various pollutants are introduced from the land, and fallen leaves are piled up on the bottom of the water and laminated. Such sludge and floats cause the water quality to be very seriously contaminated. Otherwise, it causes green tide and red tide phenomenon in the summer, and oxygen in the water is deficient, which destroys the underwater ecosystem and causes the underwater creatures, insects, and fish to die.

In order to solve the above problems, the prior arts of proposed applicants and the registered patent arts, such as No. 0543778, No. 0729843, No. 1106770, No. 1301527, etc., are presented.

However, the above-described technique has a problem in that the sludge removal operation line advances to the front and the sludge removal operation is carried out. As a result, the operation range is narrow and the work is performed repeatedly in a narrow space repeatedly.

In recent years, there have been a lot of studies to perform sludge removal work using an artificial robot in consideration of the difficult working environment of underwater sludge removal work. For example, Korean Patent No. 1364473 discloses a sewage pipe, a river, , A lake, or a seawater to efficiently clean or dredge sludge, sediment, soil, or sediments. The robot includes a robot body, a traveling part that moves the body, and a driving part that drives the traveling part A first motor, a suction motor mounted on the front of the body for suctioning the sediment, a discharge pipe communicating with the suction hopper to discharge the sucked sediment to the outside, and a discharge pipe installed inside the suction hopper to crush the sediment A second motor for driving the pulverizing screw, a second motor for driving the pulverizing screw, And a hydraulic pressure generator that is configured to control the first motor and the second motor using a high hydraulic pressure and to be remotely controllable.

In addition, in Korean Patent No. 1133091, a cleaning robot is provided with a robot body for supporting unattended cleaning of a water tank, and a driving driving part for supporting the robot body and running the robot body. The robot is disposed in front of the main body, And a tilt part which is supported by the main body and supports the suction part, and which rotates the suction part about a direction intersecting the direction in which the main body is running.

Korean Patent Registration No. 1194580 discloses an underwater cleaning robot that moves along a surface of an underwater structure and includes a traveling section having a plurality of traveling modules, a robot body, and a plurality of traveling modules in a first direction and a first direction And a cleaning module for removing foreign matter adhering to the surface of the underwater structure. The cleaning head unit includes a cleaning head unit and a cleaning head unit. The cleaning head unit includes a main body connection part connected to the robot main body so as to be rotatable about a second direction perpendicular to the first direction, And a head connecting portion connected to the robot main body so as to be rotatable about an axis direction on a plane perpendicular to the direction of the robot.
