Description

Technical Field

[0001] The invention belongs to the technical field of rust removal devices, and in particular relates to a rust removal device for a ship engine compartment and a rust removal method thereof. Background Art

[0002] Since the hull is in an aquatic environment, the engine compartment is susceptible to erosion by seawater spray, salt spray, and marine atmosphere, which will accelerate the corrosion of metal parts. The marine atmosphere usually contains a large amount of nitrides, which can make the condensed water more serious in damaging the hull structure. However, rust can cause dimensional changes and performance degradation of internal components in the engine compartment, which in turn affects the overall performance of the engine. Severely rusted parts may break due to insufficient strength, leading to equipment failure or accidents. Rust can also cause electrical failures, such as short circuits, poor grounding, etc., increasing the risk of fire and electric shock. In order to reduce the above risks, it is often necessary to remove rust from the engine compartment to complete the rust removal process.

[0003] In the process of regular rust removal of the engine compartment and its engine support frame, laser rust removal is generally used for rust removal, but the treatment effect of laser rust removal is extremely limited. In order to improve the treatment effect, rust remover is usually sprayed and rust removed with a cleaning brush. However, the rust remover itself has a certain corrosiveness. The prior art adopts a method of direct spraying instead of spraying when rusting, which easily causes the rust remover to corrode other parts and there is a certain risk.

[0004] At the same time, when removing rust from the engine compartment, after spraying the rust remover, a cleaning brush will be used to clean the rusted parts, and clean water is also needed to remove the rust stains. The whole process requires the cooperation of multiple tools. It is impossible to complete multiple tasks with one set of equipment at the same time, which has a certain impact on the overall work efficiency. Summary of the invention

[0005] The object of the present invention is to provide a ship engine compartment rust removal device and a rust removal method thereof to solve the problems raised in the above background technology.

[0006] In order to achieve the above-mentioned objectives, the present invention provides the following technical solutions: a ship engine compartment rust removal device, comprising an adjusting component, a fixing piece is fixedly sleeved on the rear end of the outer side surface of the adjusting component, a fixing plate is fixedly sleeved on the front end of the outer side surface of the adjusting component, a bellows is fixedly installed on the front end of the fixing plate, a protective cover is fixedly installed on the front end of the bellows, a recovery port is fixedly connected to the lower position of the protective cover near the front end, a recovery component is provided below the adjusting component, the top of the recovery component is connected to the recovery port, a liquid spraying component located inside the protective cover is fixedly installed on the front end of the adjusting component, a mounting piece is fixedly installed on the front end of the liquid spraying component, a movable seat is movably connected to the outer side surface of the mounting piece, a laser rust remover is fixedly installed on the middle part of the inner side surface of the movable seat, and a cleaning brush located on the outer side surface of the laser rust remover is fixedly installed on the front end of the movable seat.

[0007] Before use, the protective cover needs to be aligned with the position to be derusted. At the same time, the rear end of the adjustment component needs to be connected to the external water pump, and the fixing part needs to be connected to the external frame or robotic arm to ensure the freedom of the device and complete the preparation before rust removal.

[0008] As a further technical solution of the present invention, the adjusting assembly includes a fixed tube, the rear end of the outer side surface of the fixed tube is fixedly sleeved with a fixing member, a throttle valve is fixedly sleeved in the middle of the rear end of the fixed tube, the throttle valve is connected to an external water pump, and a piston plate is movably sleeved inside the fixed tube.

[0009] As a further technical solution of the present invention, the end of the piston plate away from the fixing piece is fixedly connected to a piston rod, the front end of the piston rod passes through the front end of the fixing tube and is fixedly connected to the liquid spraying assembly, and the outer side surface of the piston rod is movably sleeved with a return spring, and the front and rear ends of the return spring are connected to one end of the inner cavity of the fixing tube and one end of the piston plate.

[0010] As a further technical solution of the present invention, the upper and lower sides of the fixed tube near the front end are fixedly connected with spray pipes, and the upper and lower spray pipes are connected to the liquid spray assembly. When the return spring is in the extreme compression state, the piston plate is located in front of the output end of the spray pipe.

[0011] During the initial rust removal, the external water pump can be turned on and the rust remover can be pumped into the fixed tube. As the high-pressure rust remover is pumped in, the piston plate is displaced forward by the pressure. At this time, the piston plate and the piston rod are displaced forward, and the return spring is compressed until the return spring is compressed to the limit position. At this time, the rust remover can be discharged through the spray pipe and enter the interior of the liquid spray assembly.

[0012] As a further technical solution of the present invention, the liquid spray assembly includes a spray tank, the outer side surface of the spray tank is connected to the inner side surface of the protective cover through a locking frame, the top of the spray tank is fixedly connected to a power tank, the top of the power tank and the bottom end of the spray tank are fixedly connected to the upper and lower spray pipes, and the front end of the spray tank is fixedly connected to a spray head.

[0013] When the piston rod moves forward, it can synchronously drive the spray can forward, and at the same time drive the movable seat, laser rust remover and cleaning brush at the front end forward until the cleaning brush contacts the rusted position, at which time it is discharged through the spray pipe and enters the interior of the spray can, and finally discharged through the spray head. When the liquid spraying assembly moves forward, it can synchronously drive the protective cover forward, that is, the bellows is stretched. When the cleaning brush contacts the rusted position, the protective cover can completely cover the outer side of the cleaning brush. At the same time, the rust remover discharged from the spray head can be blocked by the protective cover to avoid splashing, thereby completing automatic spraying during rust removal.

[0014] By utilizing the pressure when pumping in the rust remover, the rust remover can be quickly discharged, and the pressure can be utilized to automatically move the liquid spray component and the cleaning brush forward. In conjunction with the protective cover, the device can be quickly switched to the rust removal state, and the rust remover can be automatically sprayed without splashing to other locations. It is automatically sprayed only when rust removal begins, effectively preventing the rust remover from corroding other parts and avoiding waste of the rust remover.

[0015] As a further technical solution of the present invention, a main shaft is movably connected to the middle of the power tank, an impeller is fixedly sleeved on the outer side of the main shaft, and an electric push rod is fixedly connected to the front end of the main shaft.

[0016] As a further technical solution of the present invention, the output end of the electric push rod is fixedly connected with a driving gear, the lower part of the driving gear is meshingly connected with a driven gear ring, and the inner side surface of the driven gear ring is fixedly sleeved with the outer side surface of the movable seat.

[0017] After the rust remover is sprayed to the rusted position, you can wait for a short time, control the electric push rod to extend, so that the driving gear and the driven gear ring are meshed with each other. After the adjustment is completed, clean water can be input through the external water pump. At this time, high-pressure clean water can be discharged through the spray head and act on the rusted position. When the clean water enters the power tank, it can drive the impeller to rotate. At this time, the main shaft rotates accordingly, and drives the driving gear at the front end to rotate. The driven gear ring below rotates accordingly, and finally drives the movable seat to rotate, and the cleaning brush and laser rust remover in the front rotate accordingly. At this time, the rotating laser rust remover can perform laser rust removal on the rusted position, and the cleaning brush rubs against the rusted position to complete the auxiliary cleaning process, and the clean water can directly take away the rust stains to complete the rust removal process.

[0018] By reusing the clean water pumped in during rust removal, the cleaning brush can be brought into close contact with the rusted area. At the same time, the pressure of the high-pressure clean water can be used to achieve the self-rotation of the laser rust remover and the cleaning brush, so that the spraying of clean water and the auxiliary friction cleaning process can be completed at the same time. Only one set of equipment is needed to complete the rust removal process. The whole process is completed quickly without the need for the coordinated use of multiple sets of equipment, which significantly improves work efficiency.

[0019] After the rust stains on the rusted position are removed, the connection between the throttle valve and the external water pump can be disconnected, and the heater can be connected at the same time, and the front end of the cleaning brush can be replaced with a sponge brush. At this time, the hot air can be discharged through the spray head and act on the rust removal position to dry the rust removal position. At the same time, the high-pressure air can also drive the main shaft to rotate, and finally drive the cleaning brush to rotate, and use the sponge brush at its front end to absorb water from the rusted position, completing the rapid drying process of the rust removal position.

[0020] By replacing the rust remover and clean water pumped into the device with hot air, the rust removal position can be quickly dried by the action of the hot air, and the rust removal position can be quickly absorbed with water by the rotation of the cleaning brush. The whole process is completed quickly, and the rust removal position can be dried quickly, avoiding the problem of re-rusting of the rust removal position due to the humid environment, thereby improving the quality of rust removal.

[0021] As a further technical solution of the present invention, the recovery component includes a recovery pipe, the top end of the recovery pipe is connected to the bottom end of the recovery port, the end of the recovery pipe away from the recovery port is fixedly connected to a recovery box, the top end of the recovery box is fixedly installed with an extension frame, and the top end of the extension frame is fixedly socketed with the outer side surface of the fixed pipe.

[0022] During the rust removal process, the clean water and rust remover used for rust removal are discharged through the recovery port under the guidance of the protective cover, and are transported into the interior of the recovery box through the recovery pipe, and are collected and recovered through the recovery box.

[0023] A method for removing rust from a ship engine compartment rust removal device, comprising the following steps:

[0024] S1: Before use, connect the fixing part to the external frame, connect the throttle valve to the external water pump, align the protective cover with the rusted position to be derusted, and pump the rust remover into the interior of the fixing pipe through the water pump;

[0025] S2: As the rust remover is pumped in, it applies pressure to the piston plate and compresses the return spring. The piston rod and the piston plate move forward and drive the liquid spray assembly and the protective cover to move forward as a whole. The cleaning brush and the laser rust remover move forward until the cleaning brush contacts the rusted area.

[0026] S3: When the return spring is compressed to the limit position, the rust remover can be discharged through the spray pipe and enter the interior of the liquid spray assembly. Part of the rust remover can be discharged through the spray head and blocked by the protective cover to complete the spraying process of the rust remover.

[0027] S4: After the rust remover is sprayed, the electric push rod can be turned on to control its extension, that is, the driving gear and the driven gear ring are controlled to mesh with each other, and clean water is pumped in through the water pump. At this time, the clean water can be discharged through the spray head, and the clean water entering the power tank can drive the impeller to rotate, and finally drive the movable seat to rotate;

[0028] S5: At this time, the rusted parts can be removed by the laser rust remover, and the rusted parts can be cleaned by rotating the cleaning brush. The wastewater generated by rust removal can be discharged through the recovery port and the recovery process is completed through the recovery pipe and the recovery box.

[0029] The beneficial effects of the present invention are as follows:

[0030] 1. The present invention utilizes the pressure effect when the rust remover is pumped in to enable the rust remover to be quickly discharged. At the same time, the pressure effect can be used to realize the automatic forward movement of the liquid spraying component and the cleaning brush, and cooperates with the function of the protective cover so that the device can be quickly switched to the rust removal state. At the same time, the rust remover can be automatically sprayed without splashing to other positions, and it is automatically sprayed only when the rust removal starts, effectively preventing the rust remover from corroding other parts and avoiding the waste of the rust remover.

[0031] 2. The present invention reuses the clean water pumped in during rust removal to achieve close contact between the cleaning brush and the rusted position. At the same time, the pressure of the high-pressure clean water can be used to achieve the self-rotation of the laser rust remover and the cleaning brush, so that the spraying of clean water and the auxiliary friction cleaning process are completed at the same time. Only one set of equipment is needed to complete the rust removal process. The whole process is completed quickly without the need for the coordinated use of multiple sets of equipment, which significantly improves work efficiency.

[0032] 3. The present invention replaces the rust remover and clean water pumped into the device with hot air. The rust removal position can be quickly dried by the action of the hot air, and the rust removal position can be quickly absorbed with water by the rotation of the cleaning brush. The whole process is completed quickly, and the rust removal position can be dried quickly, thereby avoiding the problem of re-rusting of the rust removal position due to the humid environment and improving the rust removal quality.
