Description

Technical Field

[0001] The utility model relates to the technical field of offshore wind power, in particular to an offshore wind power reference electrode device. Background Art

[0002] Most of the steel structure foundations of offshore wind turbines are located underwater, and cathodic protection (sacrificial anode or impressed current) is generally used to prevent the structure from being corroded by seawater. After cathodic protection is applied to the steel structure foundation, the surface potential of the structure (i.e., protection potential) is a key indicator for judging the effectiveness of the cathodic protection system, and plays an important role in the safety assessment of the wind turbine foundation structure and ensuring the safe operation of the foundation structure.

[0003] Reference electrodes have been widely used as an effective means to monitor the surface potential of steel structures. The principle is: the reference electrode, as an electrode with a known precise electrode potential, is connected to the steel structure under test through seawater to form a battery. By measuring the electromotive force of the battery, the surface potential of the steel structure under test can be calculated, thereby realizing the corrosion status monitoring of the steel structure under test.

[0004] The existing reference electrode is basically installed by fixing it on the surface of the steel structure to be measured. When the reference electrode is installed and put into the water with the steel structure to be measured, marine organisms (seaweed, marine organisms, sediments) will quickly attach to the surface of the reference electrode and gradually expand the attachment area until it is completely covered, which will eventually reduce the contact area between the reference electrode and the seawater, resulting in measurement errors. In severe cases, the reference electrode will fail completely and cannot be measured. Since the reference electrode is installed under the seawater, it is extremely difficult to replace or reinstall it after failure. The existing practice is usually to arrange professional divers to clean it regularly, which has high cleaning costs and safety risks. Utility Model Content

[0026] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0027] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0028] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0029] Reference below Figure 1-Figure 5 , the implementation of the offshore wind power reference electrode device proposed in an embodiment of the utility model is described in detail.

[0030] According to the embodiment of the utility model, the offshore wind power reference electrode device comprises: a shell 1 and a reference electrode 2.

[0031] Specifically, the shell 1 defines an installation space 11 and a first through hole 12 communicated with the installation space 11; the reference electrode 2 can be switched between a detection state and a state to be detected. In the detection state, the reference electrode 2 extends out of the installation space 11 from the first through hole 12, and in the state to be detected, the reference electrode 2 retracts from the first through hole 12 into the installation space 11, so that the first through hole 12 and the reference electrode 2 move relative to each other to scrape off the attachments on the reference electrode 2.

[0032] That is to say, the installation space 11 defined by the shell 1 can facilitate the installation of the reference electrode 2, so that the reference electrode 2 can be protected in the shell 1. When in the detection state, the reference electrode 2 can be extended from the first through hole 12 of the shell 1, so that the reference electrode 2 is connected with the seawater and the steel structure to be measured to form a battery. By measuring the electromotive force of the battery, the surface potential of the steel structure to be measured is calculated, thereby realizing the corrosion state monitoring of the steel structure to be measured. When in the state to be detected, the reference electrode 2 is retracted from the first through hole 12 into the installation space 11, so that the relative movement between the reference electrode 2 and the first through hole 12 is used to scrape off the marine organisms attached to the surface of the reference electrode 2.

[0033] Thus, the reference electrode 2 can be switched between the detection state and the state to be detected. In the detection state, the reference electrode 2 is extended from the through hole outside the shell 1 to form a connection with the seawater, and the surface potential of the steel structure to be detected is calculated. In the state to be detected, the reference electrode 2 is retracted from the through hole into the shell 1, so that the first through hole 12 scrapes off the marine organisms attached to the reference electrode 2. The offshore wind power reference electrode 2 device has a simple structure and can automatically clean the marine organisms attached to the reference electrode 2.

[0034] The driving of the reference electrode 2 also includes a moving driving member 3, which is connected to the reference electrode 2 to drive the reference electrode 2 to switch between the detection state and the state to be detected. It can be understood that the reference electrode 2 is switched between the detection state and the state to be detected by driving the reference electrode 2 to move in a telescopic manner by the moving driving member 3, so that the reference electrode 2 is extended to contact the seawater in the detection state, and is connected with the seawater and the steel structure to be detected to form a battery. By measuring the electromotive force of the battery, the surface potential of the steel structure to be detected is calculated, so as to detect the potential of the surface of the steel structure to be detected. When the reference electrode 2 is to be detected, the reference electrode 2 is retracted, so that the reference electrode 2 and the end of the first through hole 12 move relative to each other, so as to scrape off the marine organisms attached to the reference electrode 2.

[0035] As for the mobile driving member 3, the mobile driving member 3 is a plastic cylinder. It can be understood that the plastic cylinder is set to facilitate driving the reference electrode 2 to switch between the detection state and the state to be detected. The plastic material can avoid being corroded and damaged by seawater, and can also avoid the measurement error of the reference electrode 2 caused by the use of metal materials, making the measured data more accurate. Among them, the mobile driving member 3 can be installed in the housing 1 by screws.

[0036] As for the shell 1, the shell 1 has a base 13 and an upper cover 14, the base 13 and the upper cover 14 are detachably connected, the mobile driving member 3 is installed on the base 13, and the first through hole 12 is arranged at the first end of the base 13. It can be understood that the detachable arrangement of the base 13 and the upper cover 14 of the shell 1 can facilitate the installation of the mobile driving member 3 and the reference electrode 2, and at the same time, can effectively protect the accessories such as the mobile driving member 3 and the reference electrode 2 in the shell 1 from being corroded or damaged by seawater. Among them, the shell 1 can be made of high-strength plastic, such as polyoxymethylene, nylon and other materials. Such plastics have strength and hardness close to metals, and have excellent corrosion resistance, wear resistance, fatigue resistance and self-lubrication, which is convenient for ensuring the service life of the shell 1 in seawater.

[0037] For the connection between the inside and outside of the housing 1, the base 13 defines a second through hole 15, which is arranged at the second end opposite to the first end. The second through hole 15 can facilitate the air pipe 6 of the plastic cylinder in the housing 1 and the signal line 7 of the reference electrode 2 to be led to the outside of the housing 1 and connected to the control part on the upper part of the fan. The second through hole 15 can be integrally formed on the base 13.

[0038] For the arrangement of multiple reference electrode 2 devices, the base 13 defines a third through hole 16, and the third through hole 16 is arranged on one side of the base 13. It can be understood that when multiple reference electrode 2 devices need to be arranged, the signal line 7 and the air pipe 6 of the reference electrode 2 arranged in the lower reference electrode 2 device can be inserted through the third through hole 16 of the upper reference electrode 2 device, and then connected to the control part of the upper part of the fan through the second through hole 15 of the upper reference electrode 2 device. Among them, the third through hole 16 can be integrally formed on the base 13.

[0039] For the installation of the housing 1, the base 13 defines a mounting hole 17 so that the base 13 can be installed on the base of the steel structure. It can be understood that the mounting hole 17 can be arranged to facilitate the fixing of the base 13 on the base of the steel structure, so that the entire housing 1 is fixed on the base. The housing 1 can be installed on the base of the steel structure by bolts and the mounting holes 17. The number of the mounting holes 17 can be four, which are respectively arranged at the four corners of the base 13. The mounting holes 17 can be integrally formed on the base 13.

[0040] For the connection between the signal line 7 and pipeline in the shell 1 and the outside, a protective tube 4 is also included, and the protective tube 4 is connected to the second through hole 15. It can be understood that through the setting of the protective tube 4, it is convenient to lead the signal line 7 of the reference electrode 2 in the shell 1 and the air pipe 6 of the plastic cylinder to the control part on the upper part of the fan through the protective tube 4, and at the same time, it can effectively prevent the signal line 7 and the air pipe 6 from being damaged by the impact of seawater. Among them, the protective tube 4 is a seamless tube, which can be made of the same metal material as the main steel structure, fixed to the main body of the steel structure by welding, and the cathodic protection system set by the steel structure itself is used for corrosion protection. The lower port of the protective tube 4 is connected to the second through hole 15, and the upper port can be set above the water surface.

[0041] As for the connection between the reference electrode 2 and the mobile driving member 3, the reference electrode 2 is integrally formed at the output end of the mobile driving member 3, or the reference electrode 2 and the mobile driving member 3 are threadedly connected via a connector 5. It is understandable that in order to prevent corrosion from seawater and shorten the service life of the mobile driving member 3, the mobile driving member 3 can be made of a plastic cylinder, so that when the mobile driving member 3 is produced, the reference electrode 2 and the output end of the mobile driving member 3 can be integrally formed, thereby reducing the accessories to be connected and improving the assembly efficiency. It can also be threadedly connected to the output end of the mobile driving member 3 via a connector 5, making the replacement of the reference electrode 2 more convenient.
