Description

Technical Field

[0001] The invention belongs to the field of cleaning and maintenance of submarine equipment, and in particular relates to a pile foundation wall climbing cleaning device based on array electromagnetics. Background Art

[0002] Submarine pile foundations are an indispensable part of marine engineering and are widely used to support and fix structures such as offshore oil platforms, wind power towers, bridges, etc. However, due to long-term exposure to seawater environments, a large number of marine organisms and dirt, such as seaweed, shellfish, barnacles, etc., are easily attached to the surface of the submarine pile foundation. These attachments will not only increase the resistance of the pile foundation and affect its normal function, but may also cause corrosion and aging of the pile foundation, shortening its service life. Therefore, it is necessary to clean the attachments of the submarine pile foundation.

[0003] The marine environment is complex and changeable. Factors such as salt, microorganisms, and flowing water in the seawater will affect the surface of the pile foundation. Traditional cleaning methods such as manual diving cleaning are not only inefficient, but also pose a great safety risk in pile foundation wall climbing cleaning; although chemical cleaning methods can effectively remove attachments, they may cause pollution to the marine environment. The cleaning equipment and technologies currently available on the market, such as high-pressure water guns and mechanical brushing, can remove attachments on the surface of pile foundations to a certain extent, but these methods usually require complex operation and maintenance, and it is difficult to completely remove attachments, especially those marine organisms with strong adhesion.

[0004] With the enhancement of global environmental awareness, marine environmental protection has also become a focus of attention for all countries. Therefore, it is particularly important to develop a technology that can effectively clean the attachments of submarine pile foundations without causing negative impacts on the marine ecosystem. Based on this, the present invention has developed a new type of cleaning device, which not only helps to extend the service life of the pile foundation, but also contributes to the protection of the marine environment. Summary of the invention

[0005] The purpose of the present invention is to solve the problems in the prior art that pile foundations are difficult to clean due to the strong binding force of attached organisms, and a pile foundation climbing cleaning device based on array electromagnetics is proposed. The cleaning device can change according to the diameter of the pile foundation, and can adapt to the cleaning of pile foundations of different shapes and complex surfaces, and has a better cleaning effect.

[0006] The technical solution of the present invention is:

[0007] A pile foundation wall climbing cleaning device based on array electromagnetic, comprising:

[0008] A permanent magnetic crawler drive assembly, comprising two permanent magnetic crawler drive mechanisms respectively arranged at two ends of the cleaning device, wherein the permanent magnetic crawler drive mechanism comprises a mounting frame for supporting, a bearing seat fixedly connected to the mounting frame, and a permanent magnetic crawler, wherein a crawler wheel matching the permanent magnetic crawler is fixedly mounted on the bearing seat, and the permanent magnetic crawler is composed of permanent magnetic bars;

[0009] An electromagnetic array module is arranged between the two permanent magnet crawler drive mechanisms, and the electromagnetic array module is composed of a plurality of electromagnetic coils of a runway-shaped structure;

[0010] The flexible brush roller is arranged between two permanent magnetic track drive mechanisms, and comprises a roller shaft and a flexible brush fixedly mounted on the roller shaft. Both ends of the roller shaft are rotatably connected to the permanent magnetic track drive mechanisms, and the roller shaft is made of flexible material.

[0011] Furthermore, the permanent magnetic track is a chain-type structure composed of permanent magnet bars, which cooperates with a sprocket-type track wheel; the bearing seat limits the track wheel through the shaft.

[0012] Furthermore, the permanent magnet track drive mechanism is provided with driving force by a motor, and the motor is fixedly connected to the mounting frame via a motor connecting bracket.

[0013] Furthermore, the electromagnetic array module also includes a plurality of coil mounting plates for mounting electromagnetic coils, and the coil mounting plates are connected by pins.

[0014] Furthermore, connecting plates are provided on the two coil mounting plates close to the permanent magnet track driving mechanism, and are connected to the mounting frame through the connecting plates.

[0015] Furthermore, both ends of the roller shaft of the flexible brush roller are installed on the driven wheel shaft of the permanent magnetic track drive mechanism through a coupling, and the roller shaft is made of flexible material so that the flexible shaft can be bent into a corresponding curvature when the pile foundation diameter changes.

[0016] Furthermore, the driven wheel shaft drives the flexible brush roller to rotate and clean via the roller shaft.

[0017] Beneficial effects of the present invention:

[0018] (1) The array electromagnetic-based pile foundation climbing wall cleaning device provided by the present invention utilizes a composite cleaning method to clean the attached organisms and other contaminants on the seabed pile foundation. The cleaning process combines electromagnetic induction and cavitation effect. Specifically, the alternating magnetic field generated by the electromagnetic coil can not only heat the pollutants on the surface of the cleaning object, but also produce a cavitation effect in the liquid. These two effects cooperate with each other to more effectively remove the biological pollutants attached to the surface of the seabed pile foundation. The flexible brush roller can also play an auxiliary cleaning role; after using the electromagnetic coil to clean the attached organisms, some difficult-to-remove dirt and biological pollutants may still remain on the surface of the pile foundation. At this time, the flexible brush roller can further remove these residual pollutants through physical friction, thereby improving the cleaning effect and cleaning efficiency.

[0019] (2) The device of the present invention can efficiently and safely complete the cleaning operation of attached organisms or biological contaminants on the surface of the pile foundation, effectively reduce the resistance of the pile foundation in seawater, which is beneficial to the safety of maintaining the equipment, realizes unmanned cleaning, greatly saves labor costs, and ensures operational safety.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] In order to further understand the present invention, the present invention will be further described in conjunction with the accompanying drawings and embodiments.

[0027] like Figures 1 to 4 As shown, the present invention provides a pile foundation climbing wall cleaning device based on array electromagnetics, which includes a permanent magnetic track drive assembly, an electromagnetic array module and a flexible brush roller. The permanent magnetic track drive assembly includes two permanent magnetic track drive mechanisms respectively arranged at two ends of the cleaning device, and the two permanent magnetic track drive mechanisms are provided with an electromagnetic array module and a flexible brush roller, and the electromagnetic array module is composed of a plurality of electromagnetic coils 5 of a runway-type structure.

[0028] The above-mentioned pile foundation climbing wall cleaning device uses the electromagnetic coil 5 to clean attached organisms and other contaminants. During the cleaning process, an alternating current is passed through the electromagnetic coil 5 to generate an alternating magnetic field. When this alternating magnetic field acts on the object to be cleaned, an induced electromotive force is generated on the conductor (such as a metal surface), thereby inducing an electric current. This current can heat the pollutants on the surface of the cleaning object, making it easier to remove. In the process of using the electromagnetic coil 5 to clean attached organisms, the alternating magnetic field generated by the electromagnetic coil 5 can produce a cavitation effect in the liquid. The impact force generated by these tiny bubbles when they burst can help remove biological pollutants attached to the surface of the object. At the same time, the design of the runway-shaped electromagnetic coil 5 optimizes the magnetic field distribution. This shape enables the magnetic field to cover the surface of the object to be cleaned more evenly, thereby improving the cleaning efficiency and cleaning quality. The runway-shaped electromagnetic coil 5 can more effectively convert electrical energy into thermal energy during the electromagnetic induction heating process.

[0029] Furthermore, the permanent magnetic track drive mechanism includes a mounting frame 10, a bearing seat 9 fixedly connected to the mounting frame 10, and a permanent magnetic track. The mounting frame 10 is a supporting structure of the permanent magnetic track drive mechanism, the motor 3 provides driving force for the permanent magnetic track drive mechanism, and the motor connecting bracket 2 is installed at the front of the mounting frame 10, which is used to fix the motor 3 and the motor connecting bracket 2 in the permanent magnetic track drive mechanism after installation. A track wheel 7 matching the permanent magnetic track is fixedly mounted on the bearing seat 9, and the bearing seat 9 and the track wheel 7 are fixed and limited by a shaft 8, and the shaft 8 is a limiting shaft. The permanent magnetic track is composed of permanent magnet bars 1 in the form of a chain, which cooperates with the sprocket track wheel 7.

[0030] In this embodiment, the permanent magnetic track drive mechanism can provide strong traction to ensure the stable operation of the cleaning device under various plane conditions, especially on slippery or uneven surfaces. The design of the permanent magnetic track drive mechanism can effectively transmit power to the working plane, reduce sliding and energy loss, and thus improve overall energy efficiency. The permanent magnetic material used has good durability and corrosion resistance, can be used for a long time in harsh environments, and reduce maintenance frequency. At the same time, its efficient power transmission and grip enable the permanent magnetic track drive mechanism to complete its work at a lower energy consumption, meeting modern environmental protection requirements. When replacement is required, the structure of the permanent magnetic track drive mechanism is usually relatively simple, convenient and quick.

[0031] Furthermore, the electromagnetic array module is arranged between two permanent magnetic track drive mechanisms. The electromagnetic array module is composed of a plurality of coil mounting plates 4 and an electromagnetic coil 5 mounted thereon, and the electromagnetic coil 5 is designed as a runway-type structure. The plurality of coil mounting plates 4 are connected in pairs by pins, which ensures the flexibility of the electromagnetic array module, and adjusts and adapts as the permanent magnetic track drive mechanisms on both sides run at different diameters. The adjusted electromagnetic array module is close to the curvature of the surface of the pile foundation to be cleaned, which can ensure that the distance between the electromagnetic coil 5 and the surface of the pile foundation is reduced, and the minimum lifting distance of the electromagnetic coil 5 is ensured as much as possible, which greatly improves the cleaning efficiency of the cleaning device.

[0032] It should be noted that the mounting frame 10 in the permanent magnet track drive mechanism is also used to install the two side coil mounting plates 4 in the electromagnetic array module. The coil mounting plates 4 on both sides are designed with connecting plates corresponding to the mounting frame 10, and are connected to the mounting frame 10 through the connecting plates.

[0033] The flexible brush roller is also arranged between the two permanent magnetic track drive mechanisms. The roller shaft 6 of the flexible brush roller is made of flexible material. When the diameter of the pile foundation to be cleaned changes, the flexible roller shaft 6 can be bent into a corresponding curvature to ensure better fit to the pile foundation walls of different diameters. Specifically, a bearing seat 9 is installed on the mounting frame 10, and the bearing seat 9 is connected to the driving wheel. The driving function is realized by the cooperation of the driving motor and the driving wheel to ensure the rotation of the driving wheel; the driving wheel and the driven wheel are driven by a chain transmission, and the rotation of the driving wheel drives the rotation of the driven wheel. The two ends of the roller shaft 6 of the flexible brush roller are installed on the driven wheel shafts of the permanent magnetic track drive mechanisms on both sides through couplings. While the driven wheel rotates, the flexible brush roller rotates for cleaning.

[0034] The driven wheel of the permanent magnetic crawler drive mechanism is rotated to drive the flexible brush roller to rotate for cleaning, which greatly improves the energy utilization efficiency, improves the overall integration of the cleaning device, reduces the number of wiring devices, and optimizes the layout of the device. The structural design of the cleaning device not only limits the permanent magnetic crawler drive mechanisms on both sides, but also ensures that the electromagnetic coil 5 changes with the position of the permanent magnetic crawler drive mechanism, so as to be closer to the pile foundation surface.

[0035] The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments, or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, modification, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
