[0030] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0031] In the attached diagram, all identical reference numerals refer to the same components.

[0032] Example 1

[0033] like Figure 1-2 As shown, this utility model provides a portable hull rust removal and paint repair device, including a tray 1, a support plate 2, rollers 3, a threaded cylinder 4, an adjusting screw 5, a hanging plate 6, and a rust removal and grinding assembly.

[0034] The pallet 1 serves as the basic support platform for the entire device. Support plates 2 are welded and fixed to the left and right sides of its bottom. Rollers 3 are installed on the front and rear sides of the bottom of each support plate 2 through brackets and rotating shafts, so that the entire device can move flexibly on the surface of the ship.

[0035] A vertical threaded cylinder 4 is welded and fixed at the top center of the support plate 1. The upper end of the adjusting screw 5 is connected to the threaded cylinder 4 by a threaded engagement, and its lower end passes through the threaded cylinder 4 and the through hole opened on the support plate 1, extending to the bottom of the support plate 1. The bottom of the adjusting screw 5 is rotatably connected to the hanging plate 6 by a rolling bearing, so that the adjusting screw 5 does not drive the hanging plate 6 to rotate when it rotates, but only drives it to move up and down.

[0036] It should be noted that the rust removal and grinding assembly is fixedly installed at the bottom of the hanging plate 6. This assembly mainly includes two vertical plates 7, a rotating drum 8, steel wire 9, a suspension plate 10, a drive motor 11, and transmission components. The two vertical plates 7 are respectively vertically welded to the left and right sides of the bottom of the hanging plate 6. The rotating drum 8 is rotatably supported between the two vertical plates 7 through the rotating shafts at both ends. Multiple strands of hard steel wire 9 are evenly fixedly wound around the outside of the rotating drum 8 to form a grinding brush. The suspension plate 10 is horizontally welded and fixed to the bottom of the hanging plate 6. The drive motor 11 is fixedly installed on the suspension plate 10 by bolts. The transmission components are used to transmit the power of the drive motor 11 to the rotating drum 8.

[0037] In this embodiment, the transmission component is preferably a belt drive mechanism, specifically including a driving belt pulley 16, which is fixedly mounted on the output shaft of the drive motor 11; a driven belt pulley 17, which is fixedly mounted on the shaft at one end of the rotating drum 8; and a transmission belt 18, which is tightly fitted on the driving belt pulley 16 and the driven belt pulley 17.

[0038] In addition, a horizontal pipe 12 is welded and fixed between the two support plates 2. The bottom of the horizontal pipe 12 has multiple air outlets evenly opened along its length and is connected to multiple downward-extending air outlet pipes 13. On the outer side wall of the left support plate 2, a fan 14 is fixedly installed by a pad. The air outlet of the fan 14 is connected to the horizontal pipe 12 through a flexible air supply pipe 15.

[0039] Furthermore, to ensure the stability of the hanging plate 6 and the rust removal and grinding components during vertical movement and to prevent them from shaking and rotating, two sets of guide buffer mechanisms are symmetrically arranged between the bottom of the support plate 1 and the top of the hanging plate 6. Each set of guide buffer mechanisms includes a telescopic rod 19 and a spring 20. The telescopic rod 19 consists of a hollow rod and an inner rod. The top end of the hollow rod is welded to the bottom of the support plate 1, and the bottom end of the inner rod is welded to the top of the hanging plate 6. The upper end of the inner rod is inserted into the hollow rod and can slide relative to it. The two ends of the spring 20 are fixedly connected to the bottom of the support plate 1 and the top of the hanging plate 6, respectively. The telescopic length range of the telescopic rod 19 matches the range of movement of the hanging plate 6 that can be driven by the adjusting screw 5.

[0040] In addition, a U-shaped push rod 21 is welded and fixed at the bottom rear of the pallet 1. The U-shaped push rod 21 is covered with a rubber pad. The U-shaped push rod 21 is tilted backward and upward to facilitate the operator's grip and force to push the device.

[0041] The equipment usage instructions are as follows:

[0042] The operator holds the U-shaped push rod 21 and pushes the device across the hull surface. When the device reaches the area requiring treatment of rust, the push is stopped. The operator then rotates the adjusting screw 5 clockwise or counterclockwise. Due to the threaded engagement between the adjusting screw 5 and the threaded cylinder 4, the rotational motion is converted into linear motion of the screw, driving the hanging plate 6 and its bottom rust-removing and grinding components downwards until the steel wire 9 on the rotating cylinder 8 makes full contact with the rusted surface of the hull.

[0043] The power supply to the drive motor 11 is turned on. The power supply can come from the portable battery or the power interface on the ship. In this application, the power interface on the bed is used as the power supply. The drive motor 11 drives the drum 8 to rotate at high speed through the active belt pulley 16, the transmission belt 18 and the driven belt pulley 17. The steel wire 9 on it then performs powerful grinding and rust removal on the rusted parts of the hull.

[0044] Simultaneously, the blower 14 is started, and the airflow generated by the blower 14 is sent into the horizontal pipe 12 through the air supply pipe 15, and finally blown downward from each air outlet pipe 13. This airflow can promptly blow away and clean up the rust, old paint and other debris that have been polished off, exposing a clean metal surface, which is convenient for operators to directly carry out subsequent touch-up painting work, and ensures the cleanliness of the work surface.

[0045] After the operation is completed, first turn off the drive motor 11 and the fan 14, then rotate the adjusting screw 5 in the opposite direction to lift the rust removal and grinding component away from the hull surface, and then move the device to the next location for operation.

[0046] In conclusion, this utility model is approved.

[0047] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
