Abstract
Description
Technical Field
[0001] This utility model belongs to the field of high-pressure water rust removal, and in particular relates to a high-pressure water rust removal device for ship cleaning. Background Technology
[0002] High-pressure water rust removal is a method that uses high-pressure water jets to remove rust from metal surfaces. Water is pressurized to a certain pressure and sprayed onto the metal surface through a nozzle, causing the water flow to impact and carry away rust and dirt. It causes minimal damage to the metal surface and is an environmentally friendly and pollution-free rust removal method.
[0003] Ships, navigating the ocean for extended periods, are often exposed to the high salinity, acidity, and alkalinity of seawater, making them prone to corrosion. Timely treatment is crucial to prevent voyage disruptions and even shortened lifespans. A Chinese patent with publication number CN209174478U discloses an ultra-high pressure water rust removal head. This head, connected to a support, allows the rust removal cylinder to contact the workpiece to be rusted. After rust removal via a high-pressure nozzle, wastewater is collected in a receiving chamber and discharged through an outlet. Wastewater not entering the receiving chamber falls into a collecting trough and is then discharged through a pipe. This method is convenient and prevents wastewater splashing.
[0004] However, when the above-mentioned device is in use, under constant water pressure conditions, the multiple nozzles will disperse the pressure, and the impact force of a single nozzle is weak, thus affecting the final rust removal effect. Utility Model Content
[0005] The purpose of this utility model embodiment is to provide a high-pressure water rust removal device for ship cleaning, which aims to solve the problems mentioned in the background art.
[0006] This utility model embodiment is implemented as follows: a high-pressure water rust removal device for ship cleaning, comprising:
[0007] Rust removal heads, including:
[0008] The mounting base is divided into two areas, a gear cavity and a rust removal cavity, by a partition.
[0009] Water spray assembly for rust removal, the water spray assembly comprising:
[0010] A water supply shaft is axially mounted on the center of the partition via a bearing, and an installation pipe is fixedly installed radially at the end of the water supply shaft located in the rust removal chamber.
[0011] The nozzles, used to spray high-pressure water streams, are fixedly installed on the mounting pipe at equal intervals;
[0012] The rotary joint is fixedly installed on the mounting base and is coaxial with the water supply shaft. Its output end is located in the gear cavity and is fixedly connected to the water supply shaft, while its input end is located outside the mounting base and is fixedly connected to an external high-pressure water pump through the water inlet pipe.
[0013] Drive assembly, used to drive the water supply shaft to rotate.
[0014] As a further embodiment of this utility model: the rust removal head also includes multiple water extraction holes, which are evenly distributed in a ring and fixedly opened on the mounting base. The water extraction holes are connected to the rust removal chamber through a water extraction groove arranged radially along the mounting base. The multiple water extraction holes are also interconnected through a connecting cavity. A connecting pipe connected to the connecting cavity is provided on the outside of the mounting base. The connecting pipe is connected to an external vacuum device through a drain pipe.
[0015] As a further embodiment of this utility model: a sealing cover is also fixedly fitted on the outside of the mounting base. The sealing cover is configured as a cylindrical structure, the size of which is adapted to the mounting base, and the lower end of the sealing cover extends out of the end of the mounting base.
[0016] As a further aspect of this utility model: the driving component includes:
[0017] The motor is fixedly mounted on the mounting base, and its power output end moves through the mounting base and extends into the gear cavity to be fixedly connected to the drive gear.
[0018] The driven gear is fixedly mounted on the water supply shaft and meshes with the drive gear.
[0019] As a further embodiment of this utility model: a dynamic sealing ring is also fixedly installed on the water supply shaft, and the dynamic sealing ring rotates relative to the partition plate to form a rotary seal.
[0020] As a further embodiment of this utility model, it also includes a plurality of moving components for movement, wherein the moving components include casters, and the casters are fixedly mounted on the outside of the mounting base in a ring-shaped manner by a mounting bracket.
[0021] The beneficial effects of this utility model are as follows:
[0022] 1. The present invention provides a high-pressure water rust removal device for ship cleaning. By driving the rotation of the nozzles, compared with traditional fixed rust removal devices, the density of nozzles is reduced while maintaining the same working area. This increases the impact pressure of a single nozzle under constant water pressure conditions, effectively solving the pressure dispersion problem of traditional multi-nozzle systems. Under the dual action of rotational motion and fluid kinetic energy, the working coverage is effectively expanded, and multi-angle impact is achieved through continuously changing spray angles, thus improving the rust removal effect.
[0023] 2. The present invention provides a high-pressure water rust removal device for ship cleaning. The sealing cover and mounting base form a shield for the rust removal area to prevent water splashing. During rust removal, the water splashed after rust removal is extracted by an external vacuum device through a series of connected water inlet pipes, connecting pipes and connecting chambers from the water extraction hole and water extraction tank, preventing sewage from flowing out, ensuring the cleanliness of the working area and reducing the need for subsequent cleaning.
[0024] 3. The high-pressure water rust removal device for ship cleaning provided in this embodiment of the utility model improves the sealing performance between the baffle and the water supply shaft by setting a dynamic sealing ring, avoiding high-pressure water from splashing into the bearing or gear cavity, thus avoiding corrosion of the bearing, drive gear and driven gear, and reducing service life.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0031] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.
[0032] Please see Figure 1and Figure 3 This utility model provides a high-pressure water rust removal device for ship cleaning, comprising:
[0033] Rust removal head 1, including:
[0034] The mounting base 11 divides its internal space into two areas, gear cavity 13 and rust removal cavity 14, by a partition 12.
[0035] Water spray assembly 2, used for rust removal, the water spray assembly 2 includes:
[0036] The water supply shaft 21 is axially mounted on the center of the partition 12 via a bearing 121, and the end of the water supply shaft 21 located in the rust removal chamber 14 is radially fixedly mounted with an installation pipe 22.
[0037] Nozzle 23, used to spray high-pressure water jets, is fixedly installed on the mounting pipe 22 at equal intervals;
[0038] Rotary joint 24 is fixedly installed on mounting base 11 and coaxial with water supply shaft 21. Its output end is located in gear cavity 13 and fixedly connected to water supply shaft 21, and its input end is located outside mounting base 11 and fixedly connected to external high pressure water pump through water inlet pipe 4.
[0039] Drive component 3 is used to drive the water supply shaft 21 to rotate.
[0040] In practical applications, this embodiment uses a high-pressure water pump to input high-pressure water flow through the inlet pipe 4, which is then transmitted to the nozzle 23 via the water supply shaft 21 and the installation pipe 22 to spray high-pressure water onto the rust surface, thus achieving high-pressure water rust removal. During rust removal, the drive assembly 3 drives the water supply shaft 21 to rotate, which in turn drives the nozzle 23 to rotate synchronously, achieving dynamic rotational rust removal.
[0041] This embodiment, by driving the rotation of the nozzle 23, reduces the density of the nozzles 23 compared to traditional fixed rust removal devices while maintaining the same working area. This increases the impact pressure of a single nozzle under constant water pressure conditions, effectively solving the pressure dispersion problem of traditional multi-nozzle systems. Under the dual action of rotational motion and fluid kinetic energy, it effectively expands the working coverage area and achieves multi-angle impact through continuously changing spray angles, thus improving the rust removal effect.
[0042] Please see Figure 2In a preferred embodiment of this utility model, the rust removal head 1 further includes a plurality of water extraction holes 15, which are evenly distributed in a ring and fixedly opened on the mounting base 11.

A connecting pipe 153 communicating with the connecting cavity 152 is provided on the outside of the mounting base 11. The connecting pipe 153 is connected to an external vacuum device through a drain pipe 5.
[0043] Furthermore, a sealing cover 16 is also fixedly fitted on the outside of the mounting base 11. The sealing cover 16 is configured as a cylindrical structure, and its size is adapted to the mounting base 11. The lower end of the sealing cover 16 extends out of the end of the mounting base 11.
[0044] In practical application, this embodiment uses the sealing cover 16 and mounting base 11 to form a shield for the rust removal area, preventing water splashing. During rust removal, the water splashed after rust removal is extracted by an external vacuum device through a series of connected water inlet pipes 4, connecting pipes 153 and connecting cavity 152 from the water extraction hole 15 and water extraction tank 151, preventing sewage from flowing out, ensuring the cleanliness of the work area, and reducing the need for subsequent cleaning.

[0048] In practical application, the motor 31 drives the drive gear 32 to rotate, and the driven gear 33 meshes with the drive gear 32 to drive the water supply shaft 21 to rotate.
[0049] Please see Figure 3 In another preferred embodiment of this utility model, a dynamic sealing ring 122 is also fixedly installed on the water supply shaft 21, and the dynamic sealing ring 122 rotates relative to the partition plate 12 to form a rotary seal.
[0050] In practical applications, this embodiment improves the sealing performance between the partition 12 and the water supply shaft 21 by setting the dynamic sealing ring 122, preventing high-pressure water from splashing into the bearing 121 or gear cavity 13, thus avoiding corrosion of the bearing 121, drive gear 32 and driven gear 33, and reducing service life.
