[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. All publications, patent applications, patents and other references mentioned herein are incorporated by reference in their entirety.

[0025] The ship rust removal device provided by the embodiment of the application is shown in the schematic view as Figures 1-3 The ship rust removal device comprises a handle 1, one end of the handle 1 is connected with a U-shaped frame 2, a rust removal roller 3 is rotatably connected inside the frame body of the U-shaped frame 2, and support mechanisms 4 are connected to the two sides of the U-shaped frame 2.

[0026] The support mechanism 4 comprises rotary seats 41 which are symmetrically arranged and connected to the end of the U-shaped frame 2 away from the handle 1, and telescopic support rods 42 which are rotatably connected inside the rotary seats 41, and rollers 43 which are connected to the ends of the telescopic support rods 42 away from the rotary seats 41.

[0027] It is to be understood that, in the embodiment, an operator holds the handle 1 to control the movement of the whole device. The U-shaped frame 2 serves as a support structure to provide installation positions for the rust removal roller 3 and the support mechanisms 4. The motor 22 drives the rust removal roller 3 to rotate through the speed reducer 21 to perform a rust removal operation on the surface of the ship. The rotary seats 41 in the support mechanisms 4 are connected to the U-shaped frame 2 to provide rotary fulcrums for the telescopic support rods 42. The telescopic support rods 42 are rotatable relative to the rotary seats 41 to adapt to different shapes and angles of the surface of the ship, and the rollers 43 roll on the surface of the ship to assist the movement of the device and support the weight of the device.

[0028] Alternatively, as shown in Figure 1 and Figure 2 The telescopic support rod 42 comprises an outer rod 421 rotatably connected to the inside of the rotary seat 41 and an inner rod 422 inserted into the outer rod 421.

[0029] In the embodiment, the telescopic support rod 42 is composed of an outer rod 421 and an inner rod 422, and the inner rod 422 can be inserted and slid in the outer rod 421. Through the telescopic structure, the support height can be flexibly adjusted according to the height difference of the ship surface and the operation requirement, so that the roller 43 can be kept in good contact with the ship surface. The adjustable function of the support height is realized, so that the device can adapt to the ship surface of different shapes and undulations, the stability and effectiveness of the rust removal operation are ensured, and the uneven rust removal or normal operation caused by the inappropriate support height is avoided.

[0030] Optionally, as shown in Figure 1 and Figure 2 , one end of the inner rod 422 away from the outer rod 421 is connected with a roller seat 423, and the roller 43 is rotationally connected to the inside of the roller seat 423.

[0031] In the embodiment, the roller seat 423 at the end of the inner rod 422 provides a rotation connection point for the roller 43, and the roller 43 can freely rotate in the roller seat 423. When the device moves on the ship surface, the rotation of the roller 43 can effectively reduce the friction between the device and the ship surface, so that the device moves more smoothly. The cooperation design of the roller 43 and the roller seat 423 reduces the resistance when the device moves, improves the moving efficiency of the device on the ship surface, reduces the labor intensity of the operator, and also helps to ensure the continuity and uniformity of the rust removal operation.

[0032] Optionally, as shown in Figure 1 and Figure 3 , the end of the outer rod 421 away from the inner rod 422 is provided with a groove 424, the groove body of the groove 424 is provided with a torsional spring 425, and the torsional spring 425 is coaxially arranged with the outer rod 421.

[0033] In the embodiment, the torsional spring 425 in the groove 424 at one end of the outer rod 421 plays a role when the telescopic support rod 42 rotates and is stressed. When the device moves on the ship surface and encounters uneven areas, the torsional spring 425 will generate a certain torsional force, so that the telescopic support rod 42 has the tendency of automatic reset and maintaining a certain angle, so as to ensure that the roller 43 is always in contact with the ship surface.

[0034] Optionally, as shown in Figure 1 and Figure 3 , the end of the outer rod 421 away from the groove 424 is externally connected with a convex disc 427, and the outer part of the inner rod 422 is sleeved with a spring 426, one end of the spring 426 abuts against the convex disc 427, and the other end abuts against the rotating seat 41.

[0035] In this embodiment, the inner rod 422 is sleeved with a spring 426, one end of which abuts against a convex disc 427, and the other end of which abuts against the rotating seat 41. When the device exerts pressure on the surface of the ship for rust removal, the spring 426 will elastically deform according to the size of the pressure, thereby playing a buffering role. The convex disc 427 can adjust the compression degree of the spring 426, thereby adjusting the elastic force of the spring 426. The buffering role of the spring 426 makes the pressure of the device on the surface of the ship more uniform and controllable, avoids damaging the surface of the ship due to excessive pressure, and enhances the stability of the device during operation. The adjustment function of the convex disc 427 to the elastic force of the spring 426 can be personalized according to different ship surface materials and rust removal requirements.

[0036] Optionally, as shown in Figure 1 and Figure 2 , the convex disc 427 is in a ring structure, and the inner ring surface of the convex disc 427 is connected with the outer surface of the outer rod 421 through threads.

[0037] In this embodiment, the convex disc 427 is in a ring structure and is connected with the outer rod 421 through threads. By rotating the convex disc 427, the position of the convex disc 427 on the outer rod 421 can be changed, thereby adjusting the compression degree of the spring 426 and realizing accurate adjustment of the elastic force of the spring 426. The design of the threaded connection makes the adjustment operation of the convex disc 427 simple and convenient, can quickly and accurately adjust the elastic force of the spring 426 according to the actual operation situation, improves the adaptability and flexibility of the device, and meets the requirements of different ship rust removal operations.

[0038] Optionally, as shown in Figure 1 , one side surface of the frame body of the U-shaped frame 2 is connected with a speed reducer 21, the output end of the speed reducer 21 is rotationally connected with the rust removal roller 3, and the input end of the speed reducer 21 is connected with a motor 22.

[0039] In this embodiment, after the motor 22 is started, power is output to the speed reducer 21, the speed reducer 21 reduces the rotating speed of the motor 22 and increases the torque, and then transmits power to the rust removal roller 3, so that the rust removal roller 3 rotates at a suitable rotating speed and torque, thereby efficiently removing rust marks on the surface of the ship.

[0040] The specific operation mode of the device is as follows:

[0041] When performing ship rust removal operation, the operator holds the handle 1, moves the device to the position where rust removal is needed. According to the shape and height of the surface of the ship, the length of the telescopic supporting rod 42 is adjusted, so that the roller 43 contacts the surface of the ship and maintains appropriate pressure.

[0042] The starting motor 22 drives the speed reducer 21, and then drives the rust removal roller 3 to rotate. The operator pushes the device, and the roller 43 rolls on the surface of the ship, and drives the rust removal roller 3 to remove rust on the surface of the ship. During the movement, the torsion spring 425 and the spring 426 of the telescopic supporting rod 42 automatically adjust the telescopic and angle according to the ups and downs of the surface of the ship, so that the rust removal roller 3 always maintains good contact with the surface of the ship, and the rust removal effect is improved.
