Description

Technical Field

[0001] The present invention relates to the technical field of ship rust removal, and particularly to a ship rust removal device. Background Art

[0002] After the whole ship is launched and sails in the ocean for a period of time, the surface of the hull shell is extremely prone to rust due to electrochemical corrosion and marine biological corrosion. It is necessary to repair the surface of the hull in time, that is, surface rust removal and secondary anti-corrosion treatment. Due to the certain curvature of the hull surface, when grinding, a bowl-shaped wire brush is generally used as the grinding head. For example, in the patent with the authorization announcement number CN220718896U, a ship surface rust removal device is disclosed. Through the overall structural cooperation design, consumables such as spraying materials, water, and rust removers are not required during rust removal, saving resources. At the same time, the rust removal speed is faster, the rust removal area is wider, the rust removal efficiency is higher, and the rust removal quality is higher. The surface roughness after rust removal is higher, and flash rust will not occur, which is more suitable for the subsequent painting process. When the treatment component is attached to the hull surface with a certain curvature, due to the flexible characteristics of the bowl-shaped wire brush body, after it is deformed under pressure, the fitting degree between the treatment component and the hull surface is effectively improved.

[0003] Currently, for existing rust removal and grinding equipment, in order to fit the hull surface, a bowl-shaped wire brush is generally used as the grinding head. Similar to the above-mentioned prior art, it can avoid water pollution caused by using a spray gun. However, when the bowl-shaped wire brush is grinding, the surrounding environment is dry, which is easy to raise a large amount of rust dust, affecting the surrounding environment. If a large amount of dust adheres to the hull surface, it is difficult for the staff to distinguish the rust removal situation of the hull surface. Moreover, after the bowl-shaped wire brush grinds for a period of time, a large amount of rust powder and paint debris will adhere to the inside of the bowl-shaped wire brush, affecting the grinding effect. If the grinding is stopped midway for cleaning, it is relatively troublesome and time-consuming. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides a ship rust removal device that can switch the grinding head during the grinding process and can also clean the switched grinding head during the grinding process.

The bowl-shaped wire brush is in a rotating state, and the rotating bowl-shaped wire brush contacts the brush plate, so that during rinsing, the cleaning is relatively clean.

[0019] 4. Through the setting of the knocking component in the present invention, it is possible to knock on the back of the bowl-shaped wire brush when the bowl-shaped wire brush is performing rust removal and grinding work, causing the bowl-shaped wire brush to vibrate, and using the vibration to loosen and fall off the rust debris, metal powder, etc. attached to the wires of the bowl-shaped wire brush, thereby further improving the cleaning effect of the bowl-shaped wire brush and enabling it to maintain better cleanliness and working efficiency.

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0033] Please refer to Figures 1-8 , a ship rust removal device, including a support rod 3, an installation housing 1 fixedly installed on the support rod 3, and a bowl-shaped wire brush 2 arranged on one side of the installation housing 1. There are two bowl-shaped wire brushes 2. A rotating rod 10 is fixedly installed between the two bowl-shaped wire brushes 2. Openings 32 are provided on both sides of the installation housing 1, and a slide opening 31 is provided inside the installation housing 1. A first motor 4 is fixedly installed inside the installation housing 1. The output end of the first motor 4 is provided with a rotating assembly for controlling the rotation and replacement of the bowl-shaped wire brush 2. A flushing assembly for flushing the bowl-shaped wire brush 2 is installed inside the installation housing 1. The bottom of the installation housing 1 is fixedly communicated with a hopper 7, and the lower end of the hopper 7 is fixedly communicated with a diversion pipe 6. By installing bowl-shaped wire brushes 2 at both ends of the rotating rod 10, the area between the two bowl-shaped wire brushes 2 can be switched at any time. When switching to the bowl-shaped wire brush 2 inside the installation housing 1, it can be flushed by the flushing assembly to remove the rust powder and paint debris adhering to its interior, and then flow away through the diversion pipe 6. Subsequently, it is collected and processed to avoid discharging it to the outside and causing water pollution. The washed bowl-shaped wire brush 2 is in a wet state. During the grinding process, its outer surface is more likely to adhere to dust, which can reduce dust emission and reduce the adhesion of a large amount of rust dust to the hull grinding area, affecting the staff's judgment of the rust removal situation on the hull surface.

[0034] Outside the installation housing 1, there is a shielding component that shields the sliding opening 31 and the opening 32. Inside the upper wall of the installation housing 1, there is a cavity 14. A connection component for controlling the movement of the shielding component is rotatably installed in the cavity 14. The connection component is used to control the opening and closing of the sliding opening 31 and the opening 32. The shielding component includes connection housings 22 fixedly installed on both sides of the installation housing 1. At the lower end of the connection housing 22, there is a baffle 8 rotatably connected to close the opening 32. In both connection housings 22, there is a first gear 25 rotatably connected and fixedly connected to the baffle 8. A sliding plate 13 for closing the sliding opening 31 is slidably connected to the inner side of the installation housing 1. At the lower end of the sliding plate 13, there is a clamping opening 20 fixedly opened. At the upper end of the sliding plate 13, there is a transmission rod 21 fixedly connected. When it is necessary to switch the bowl-shaped wire brush 2, control the movement of the baffle 8 and the sliding plate 13 to open the opening 32 and the sliding opening 31. After the bowl-shaped wire brush 2 is switched, control the movement of the baffle 8 and the sliding plate 13 to close the opening 32 and the sliding opening 31, so as to prevent a large amount of sewage from splashing to the outside when flushing the bowl-shaped wire brush 2.

[0035] The rotating component includes a cylinder 9 rotatably sleeved outside the first motor 4. The rotating rod 10 passes through the cylinder 9 and is rotatably connected to it. At the lower end of the cylinder 9, there is a support plate 34 rotatably installed and fixedly connected to the installation housing 1. The output end of the first motor 4 is fixedly connected with an installation cylinder 35. At the lower end of the installation cylinder 35, there is a first bevel gear 16 fixedly connected. On one side of the first bevel gear 16, there is a second bevel gear 18 fixedly sleeved on the rotating rod 10 and meshed with it. A limiting component is arranged between the installation cylinder 35 and the rotating rod 10. The limiting component includes an electric push rod 17 fixedly installed on the installation cylinder 35. The output end of the electric push rod 17 is rectangularly arranged. On the rotating rod 10, there is a through hole 19 connected to the electric push rod 17. The first bevel gear 16 and the second bevel gear 18 are of the same size. When the first bevel gear 16 rotates one circle, it drives the second bevel gear 18 to rotate one circle. When the first motor 4 works, it drives the first bevel gear 16 to rotate. The first bevel gear 16 drives the second bevel gear 18 to rotate. The second bevel gear 18 drives the rotating rod 10 to rotate. The rotating rod 10 drives the bowl-shaped wire brush 2 to rotate for grinding work. When it is necessary to switch the bowl-shaped wire brush 2, start the electric push rod 17 to work so that its working end is connected to the through hole 19 (when the first motor 4 is performing grinding work, the rotation period is an integer number of circles). Control the opening 32 and the sliding opening 31 to open, and start the first motor 4 to rotate half a circle to switch the bowl-shaped wire brush 2.

[0036] As a further solution of the present invention, the connection component includes a second gear 29 rotatably installed on the lower wall of the cavity 14. A sawtooth plate 28 is meshed and connected to one side of the second gear 29. The two ends of the sawtooth plate 28 are respectively meshed with the corresponding first gears 25. The sawtooth plate 28 is a Z-shaped plate for controlling the rotation directions of the two first gears 25 to be opposite. A second motor 11 is fixedly installed on the upper wall of the installation housing 1. The output end of the second motor 11 is meshed with the second gear 29. A first pulley 23 is also fixedly sleeved on the output end of the second motor 11. A transmission component is arranged between the first pulley 23 and the transmission rod 21 for controlling the lifting of the sliding plate 13. The transmission component includes a second pulley 27 rotatably installed on the lower wall of the cavity 14. A transmission belt 26 is sleeved between the second pulley 27 and the first pulley 23. A sliding ball 15 is fixedly connected to the inner side of the second pulley 27. A spiral groove 24 for sliding connection with the sliding ball 15 is formed on the outer side of the transmission rod 21. The diameter of the first pulley 23 is larger than that of the second pulley 27. By controlling the operation of the second motor 11, the first pulley 23 and the second gear 29 can be driven to rotate. The rotation of the second gear 29 drives the sawtooth plate 28 to move. The sawtooth plate 28 drives the first gear 25 to rotate. The first gear 25 drives the baffle 8 to rotate. Since the sawtooth plate 28 is a Z-shaped plate for controlling the rotation directions of the two first gears 25 to be opposite, the opening 32 can be opened. At the same time, when the first pulley 23 rotates, through the cooperation of the transmission belt 26, the second pulley 27 can be driven to rotate. Through the cooperation of the sliding ball 15 and the spiral groove 24, the transmission rod 21 can be driven to move upward. The transmission rod 21 drives the sliding plate 13 to move upward to open the sliding port 31. By controlling the second motor 11 to reverse, the baffle 8 can be controlled to reverse and reset to close the opening 32. At the same time, the sliding plate 13 moves downward to close the sliding port 31.

[0037] As a further solution of the present invention, the flushing component includes a fixed pipe 30 fixedly installed on the upper wall of the installation housing 1. A plurality of nozzles 33 are fixedly communicated with the lower arc surface of the fixed pipe 30. A water inlet pipe 5 is fixedly communicated with the outer side of the fixed pipe 30. A brush plate 12 is fixedly installed on the side wall of the installation housing 1. During the grinding process, the bowl-shaped wire brush 2 in the installation housing 1 is flushed. The bowl-shaped wire brush 2 is in a rotating state. The rotating bowl-shaped wire brush 2 contacts the brush plate 12, so that during flushing, the cleaning is relatively clean.

[0038] The working principle of this embodiment:

[0039] During operation, in the state as Figure 2 shown, the first motor 4 is started. The first motor 4 drives the first bevel gear 16 to rotate. The first bevel gear 16 drives the second bevel gear 18 to rotate. The second bevel gear 18 drives the rotating rod 10 to rotate. The rotating rod 10 drives the bowl-shaped wire brush 2 to rotate for grinding work;

[0040] At the same time, the water inlet pipe 5 is connected to the external water delivery equipment, and the guide pipe 6 is connected to the external collection equipment. The water inlet pipe 5 sends water to the fixed pipe 30, and the bowl-shaped wire brush 2 is rinsed through the nozzle 33 to remove the rust powder and paint debris inside it, and then it flows away through the guide pipe 6, and is subsequently collected and processed to avoid being discharged to the outside to cause water pollution. During the grinding process, the bowl-shaped wire brush 2 installed in the housing 1 is rinsed, and the bowl-shaped wire brush 2 is in a rotating state. The rotating bowl-shaped wire brush 2 contacts the brush plate 12, so that it is cleaned more thoroughly during rinsing;

[0041] When the bowl-shaped wire brush 2 needs to be switched, the electric push rod 17 is started to work so that its working end is connected to the perforation 19 (when the first motor 4 is performing the grinding work, the rotation cycle is an integer circle, so each time the first motor 4 stops working, the working end of the electric push rod 17 corresponds to the position of the perforation 19);

[0042] The second motor 11 is started to work, which can drive the first pulley 23 and the second gear 29 to rotate. The rotation of the second gear 29 drives the sawtooth plate 28 to move. The sawtooth plate 28 drives the first gear 25 to rotate. The first gear 25 drives the baffle 8 to rotate. Since the sawtooth plate 28 is a Z-shaped plate, it is used to control the rotation directions of the two first gears 25 to be opposite, so that the opening 32 can be opened. At the same time, when the first pulley 23 rotates, the second pulley 27 can be driven to rotate through the cooperation of the transmission belt 26. The transmission rod 21 can be driven to move upward through the cooperation of the sliding ball 15 and the spiral groove 24. The transmission rod 21 drives the slide plate 13 to move upward to open the sliding port 31.

[0043] Then start the first motor 4 and rotate it half a circle to switch the bowl-shaped wire brush 2. The bowl-shaped wire brush 2 after cleaning is in a wet state. During the grinding process, its outer surface is more likely to adhere to dust, which can reduce dust and reduce the large amount of rust dust attached to the grinding part of the hull, which affects the staff's judgment of the rust removal condition of the hull surface;

[0044] After the switching is completed, the second motor 11 is controlled to rotate in the reverse direction, and the baffle 8 can be controlled to reverse and reset to close the opening 32 , while the slide plate 13 moves downward to close the sliding opening 31 .

[0045] A knocking assembly is provided on the inner wall of the mounting shell 1 near the back side of the bowl-shaped wire brush 2, and the knocking assembly includes a knocking rod 36 and an elastic member 37. A groove 38 is provided on the inner wall of the mounting shell 1 near the back side of the bowl-shaped wire brush 2, the knocking rod 36 is slidably set in the groove 38, the elastic member 37 is set in the groove 38, and the two ends of the elastic member 37 respectively contact the knocking rod 36 and the inner wall of the mounting shell 1, an annular groove 39 is provided on the back of the bowl-shaped wire brush 2, and a plurality of contact protrusions 40 are evenly arranged inside the annular groove 39 along the circumferential direction, and an annular step is formed between all the contact protrusions 40, and one end of the knocking rod 36 contacts the contact protrusion 40.

[0046] Specifically, during the rust removal process of the bowl-shaped wire brush 2, the wires of the bowl-shaped wire brush 2 will embed into the rust. Therefore, a knocking component is arranged inside the installation housing 1. When the bowl-shaped wire brush 2 rotates, the annular steps formed by the multiple abutting protrusions 40 rotate synchronously. As the bowl-shaped wire brush 2 rotates, the inclined sides of the multiple abutting protrusions 40 sequentially abut against the knocking rod 36, so that the abutting protrusions 40 collide with the knocking rod 36. During this process, the elastic force of the elastic member 37 can ensure that the knocking rod 36 always abuts against the abutting protrusions 40.

[0047] Through the arrangement of the knocking component, it is possible to knock on the back of the bowl-shaped wire brush 2 during the grinding and rust removal work, causing the bowl-shaped wire brush 2 to vibrate, and using the vibration to loosen and fall off the rust debris, metal powder, etc. attached to the wires of the bowl-shaped wire brush 2, thereby further improving the cleaning effect of the bowl-shaped wire brush 2 and enabling it to maintain better cleanliness and working efficiency. Moreover, knocking on the back of the bowl-shaped wire brush 2 can rearrange its wires and restore a certain elasticity, so that during subsequent rust removal, the wires can more effectively remove rust.

[0048] It should be noted that in order to avoid jamming when the end of the knocking rod 36 moves between the inclined surfaces of two adjacent abutting protrusions 40, the outer edge of the knocking rod 36 can be set to be arc-shaped, thereby improving the smoothness of knocking. And users can add the number of knocking components according to the required vibration intensity to ensure the vibration effect.

[0049] Furthermore, the other end of the knocking rod 36 is fixedly connected with an extension member 41. The extension member 41 sequentially passes through the elastic member 37 and the installation housing 1 and extends to the outside of the installation housing 1. When the bowl-shaped wire brush 2 is replaced, the extension member 41 can be pulled to realize the abutting connection between the knocking rod 36 and the abutting protrusions 40, so as to facilitate the replacement of the bowl-shaped wire brush 2.

[0050] A waterproof plate 42 is fixedly connected to the outer wall of the bowl-shaped wire brush 2, and the waterproof plate 42 is circular.

[0051] By setting the waterproof plate 42, the water flow sprayed by the nozzle 33 can be blocked to prevent the water flow from flowing into the groove 38 and hindering the use effect of the knocking component.

[0052] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can make equivalent replacements for its features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
