[0002] In the heavy shipbuilding industry, ship maintenance is crucial. Cleaning the bottom of a ship is a crucial step in ship maintenance, crucial for both navigational safety and the lifespan of the vessel. Traditional methods for cleaning the bottom rely on manual labor using tools such as scrapers and wire brushes, or on the use of ship anti-marine systems to prevent marine growth. These methods are inefficient for cleaning marine growth from the bottom of the ship. Underwater cleaning operations are prone to hull damage, pose a high risk, generate chlorine and metal ions that pollute the marine environment, and result in incomplete removal of marine growth, making hull maintenance difficult. Consequently, a new bottom cleaning device for heavy shipbuilding is urgently needed to address these challenges. Summary of the Invention

[0013] Preferably, the bottom of the base is provided with evenly distributed anti-slip grooves.

[0014] Compared with the prior art, the present invention provides a ship bottom cleaning device for shipbuilding and heavy industry, which has the following beneficial effects:

[0015] 1. The ship bottom cleaning device for heavy industry is provided with a first motor, a rotating shaft bracket, an electric push rod, an electric slide rail, a slider, a guide rail, an annular groove and a universal wheel. The first motor can drive the rotating shaft bracket, the rotating bin and the card seat to rotate and adjust the operating range of the cleaning brush. At this time, the electric push rod plays a supporting role at the bottom. During the rotation of the electric push rod, the universal wheel rolls inside the annular groove. The annular groove defines the motion trajectory of the universal wheel, thereby enhancing the stability of the device during rotation. The electric push rod pushes upward to change the angle between the cleaning surface formed by the three cleaning brushes and the ground, thereby achieving multi-angle removal of attachments and adapting to ships of different shapes. During the pushing process of the electric push rod, the rotating shaft bracket and the output end of the first motor rotate relative to each other, the top of the electric push rod and the slider rotate relative to each other, 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 movement direction, further expanding the cleaning range of the ship bottom. Without moving the base, large-scale, multi-angle and automated cleaning of the ship bottom can be achieved, thereby comprehensively improving the cleaning efficiency of the ship bottom.

[0016] 2. The ship bottom cleaning device for heavy industry uses a brush head bracket and a disturbance rod. During the rotation of the cleaning brush, the bristles hit the disturbance rod. The vibration generated by the hitting process causes foreign matter attached to the surface of the bristles to fall off by themselves, realizing real-time automatic cleaning of the cleaning brush and ensuring that the cleaning brush always has perfect refreshing ability. The transverse grooves on the surface of the disturbance rod can increase the frequency of vibration.

[0017] 3. The ship bottom cleaning device for heavy industry use is equipped with a water tank, a water pump, a liquid level window, a metal shaped hose and a nozzle. Cleaning liquid can be poured into the water tank through the water inlet. The liquid level window allows the staff to grasp the water level inside the water tank in real time. The water pump draws out the cleaning liquid from the water tank and sprays the cleaning liquid onto the bottom of the ship through the outlet pipe, the metal shaped hose and the nozzle, thereby optimizing the cleaning effect of the cleaning brush. The metal shaped hose can be bent, and the angle after bending is fixed, which is convenient for adjusting the spray angle of the nozzle to adapt to different types of cleaning environments.

[0018] 4. The ship bottom cleaning device for heavy industry is provided with a bellows, an air outlet, a waste trough, a latch and a baffle. The bellows is connected to the air pump system through an air pipe joint to convey airflow into the bellows. The airflow is blown from the air outlet to the top of the card seat, thereby removing debris generated during the operation of the cleaning brush outside the card seat, eliminating obstacles during the rotation of the cleaning brush, and ensuring smooth operation of the device. The waste trough is provided opposite to the air outlet, and the waste blown away from the card seat by the air flow is collected to avoid contaminating the working environment. The baffles on both sides of the waste trough play a blocking role to prevent the waste from escaping before reaching the waste trough. The waste trough and the card seat are detachably connected by a latch, which is convenient for cleaning the waste collected in the waste trough. BRIEF DESCRIPTION OF THE DRAWINGS
