[0014] Compared with the prior art, the present invention provides a ship bottom cleaning device for shipbuilding heavy industry, and has the following beneficial effects: 1. The ship bottom cleaning device for shipbuilding industry, by setting a first motor, a rotating shaft bracket, an electric push rod, an electric slide rail, a slider, a guide rail, an annular groove and universal wheels, the first motor can drive the rotating shaft bracket, the rotating bin and the clamping seat to rotate, adjusting the working range of the cleaning brush. At this time, the electric push rod plays a supporting role below. During the rotation of the electric push rod, the universal wheels roll inside the annular groove, and the movement track of the universal wheels is limited by the annular groove, enhancing the stability performance of the device during rotation. The electric push rod can be pushed upward to change the angle between the cleaning surface formed by the three cleaning brushes and the ground, realizing multi-angle removal of attachments, adapting to ships with different shapes. During the pushing process of the electric push rod, the rotating shaft bracket rotates relative to the output end of the first motor, and the top of the electric push rod rotates relative to the slider, and the slider slides along the guide rail. The electric slide rail can drive the sliding bracket to move and change the cleaning position of the cleaning brush along the moving direction, further expanding the cleaning range of the ship bottom. Without moving the base, it can achieve large-range, multi-angle and automatic cleaning of the ship bottom, comprehensively improving the cleaning efficiency of the ship bottom.

[0015] 2. The ship bottom cleaning device for shipbuilding industry, by setting a brush head bracket and a disturbing rod, during the rotation of the cleaning brush, the bristles strike the disturbing rod, and the vibration generated during the striking process makes the foreign matters attached to the surface of the bristles fall off automatically, realizing real-time automatic cleaning of the cleaning brush, ensuring that the cleaning brush always has perfect cleaning ability. The transverse grooves on the surface of the disturbing rod can increase the vibration frequency.

[0016] 3. The ship bottom cleaning device for shipbuilding industry, by setting a water tank, a water pump, a liquid level window, a metal shaping hose and a nozzle, cleaning liquid can be poured into the water tank through the water injection port. The liquid level window is convenient for the staff to grasp the water level inside the water tank in real time. The water pump pumps out the cleaning liquid in the water tank, and sprays the cleaning liquid to the ship bottom through the water outlet pipe, the metal shaping hose and the nozzle, optimizing the cleaning effect of the cleaning brush. The metal shaping hose can be bent and the angle is fixed after bending, which is convenient for adjusting the spraying angle of the nozzle to adapt to different types of cleaning environments.

[0017] 4. The ship bottom cleaning device for shipbuilding industry, by setting a wind box, an air outlet, a waste material groove, a bolt and a baffle, the wind box is connected to the air pump system through an air pipe joint to convey air flow into the wind box. The air flow turns and blows towards the top of the clamping seat, removing the debris generated during the operation of the cleaning brush outside the clamping seat, removing the obstacles during the rotation of the cleaning brush, ensuring the smooth operation of the device. The waste material groove is arranged opposite to the air outlet to collect the waste material blown away from the clamping seat by the air flow, avoiding polluting the working environment. The baffle plays a blocking role on both sides of the waste material groove to prevent the waste material from escaping before reaching the waste material groove. The waste material groove and the clamping seat are detachably connected through a bolt, which is convenient for cleaning the waste material collected in the waste material groove.
