[0002] An offshore wind power pile is a basic structure for supporting an offshore wind turbine generator and is an important part of an offshore wind farm. Potential detection is mainly used for the safety detection of the internal electrical system of a building to ensure that the potential difference between electrical devices is small enough to reduce the risk of electric shock, and to measure the potential values of different parts of a steel structure to understand the operation of the cathodic protection system, evaluate the corrosion condition of the structure, the performance of the anti-corrosion system and the protection effect.

[0003] In the prior art, especially when detecting the potential of an offshore wind power pile through a potential detector, the operation of the cathodic protection system is understood by measuring the potential values of different parts of the pile, and the corrosion condition of the structure, the performance of the anti-corrosion system and the protection effect are evaluated. However, during the detection process, the potential detector often needs to be manually held for detection. Since there are many parts to be detected, the method of manually holding the potential detector for detection is time-consuming and laborious, and the situation of missed detection often occurs in the manual holding detection method, so it is difficult to comprehensively detect all parts of the pile, and the situation of missed detection of the detection parts may occur. Summary of the Utility Model

[0004] The utility model provides a device for detecting the potential of an offshore wind power pile foundation, which is beneficial to easily and labor-savingly detect the potential of an offshore wind power pile and is beneficial to ensuring the comprehensiveness of detection, etc.

[0005] In order to solve the problems of the prior art, the utility model discloses a device for detecting the potential of an offshore wind power pile foundation, which comprises a detection frame and a detection screen, and the detection screen is installed on the right side of the inner bottom end of the detection frame;

[0006] A circular frame is arranged on the left side of the detection frame, a circular gear is fixedly sleeved on the periphery of the circular frame, an L-shaped support plate is arranged below the circular gear, a potential detector is arranged at the right lower end of the L-shaped support plate, and a circumferential detection driving assembly is arranged above the L-shaped support plate;

[0007] A lifting detection driving assembly is arranged on the left side inside the detection frame.

[0008] Further, a storage battery is installed at the inner top end of the L-shaped support plate.

[0009] Further, an electric cylinder is fixed on the inner side wall of the L-shaped support plate, and the potential detector is connected to the power end of the electric cylinder.

[0010] Further, the circumferential detection drive assembly includes a drive motor, a main gear, and a slider. The drive motor is fixed to the upper end of the L-shaped support plate. The main gear is connected to the power end of the drive motor, and the main gear meshes with the annular gear.

[0011] Further, an annular rail groove is formed at the lower end of the annular frame. The slider is fixed to the upper end of the L-shaped support plate, and the slider is slidably connected to the annular rail groove.

[0012] Further, the lifting detection drive assembly includes a forward and reverse motor, a lead screw, a guide shaft, and a lifting plate. The forward and reverse motor is fixed to the inner top end of the detection frame. One end of the lead screw is connected to the power end of the forward and reverse motor, and the other end of the lead screw is rotatably connected to the inner bottom end of the detection frame.

[0013] Further, the guide shaft is fixed to the left end inside the detection frame. The lifting plate is slidably sleeved around the guide shaft, and the lead screw threadedly penetrates through the lifting plate. The upper end of the annular frame is fixed to the lower end of the lifting plate.

[0014] Compared with the prior art, the beneficial effects achieved by the present utility model are as follows:

[0015] 1.

Detailed implementation mode

[0022] A device for detecting the potential of offshore wind power pile foundations:

[0023] As Figures 1-4 As shown, in this embodiment, it includes a detection frame 1 and a detection screen 2. The detection screen 2 is installed on the right side of the inner bottom end of the detection frame 1. An annular frame 3 is provided on the left side of the detection frame 1. An annular gear 4 is fixedly sleeved on the outer periphery of the annular frame 3. An L-shaped support plate 6 is provided below the annular gear 4. A potential detector 5 is provided at the lower right end of the L-shaped support plate 6. And a circumferential detection drive assembly is provided above the L-shaped support plate 6. The circumferential detection drive assembly includes a drive motor 9, a main gear 10 and a sliding block 12. The drive motor 9 is fixed at the upper end of the L-shaped support plate 6. The main gear 10 is connected to the power end of the drive motor 9. And the main gear 10 meshes with the annular gear 4. An annular rail groove 11 is opened at the lower end of the annular frame 3. The sliding block 12 is fixed at the upper end of the L-shaped support plate 6. And the sliding block 12 is slidably connected to the annular rail groove 11.

[0024] When detecting the potential of an offshore wind power pile through this device, on the premise that the annular frame 3 is sleeved around the offshore wind power pile, the drive motor 9 works to drive the drive gear 10 to rotate. Since the drive gear 10 meshes with the annular gear 4 and the sliding block 12 is slidably connected in the annular rail groove 11, the drive gear 10 will rotate along the annular gear 4. At the same time, it will drive the sliding block 12 to slide along the annular track. Therefore, the sliding block 12 will drive the L-shaped support plate 6, the electric cylinder 7 and the potential detector 5 to move together, which can conveniently drive the potential detector 5 to automatically detect the potential around the pile. The detection work is automatic and convenient, and there is no need for manual holding of the detection. Therefore, the detection work is easy and labor-saving.

[0025] As Figure 2 As shown, in this embodiment, a storage battery 8 is installed at the inner top end of the L-shaped support plate 6. An electric cylinder 7 is fixed on the inner side wall of the L-shaped support plate 6. The potential detector 5 is connected to the power end of the electric cylinder 7.

[0026] The storage battery 8 supplies power to the potential detector 5 and the electric cylinder 7, which is beneficial to ensuring the normal power supply of the potential detector 5 during rotation detection. Moreover, through the telescoping of the electric cylinder 7, the detection distance of the potential detector 5 to the pile can be conveniently adjusted, which is beneficial to ensuring the normal detection distance.

[0027] As Figure 4As shown, in this embodiment, a lifting detection drive assembly is provided on the left side inside the detection frame 1. The lifting detection drive assembly includes a reversible motor 13, a lead screw 14, a guide shaft 15, and a lifting plate 16. The reversible motor 13 is fixed to the top end inside the detection frame 1. One end of the lead screw 14 is connected to the power end of the reversible motor 13, and the other end of the lead screw 14 is rotatably connected to the bottom end inside the detection frame 1. The guide shaft 15 is fixed to the left end inside the detection frame 1. The lifting plate 16 is slidably sleeved around the outer periphery of the guide shaft 15, and the lead screw 14 threadedly penetrates through the lifting plate 16. The upper end of the annular frame 3 is fixed to the lower end of the lifting plate 16.

[0028] By the operation of the reversible motor 13 driving the lead screw 14 to rotate, the lead screw 14 will drive the lifting plate 16 to slide up and down along the guide shaft 15. The lifting plate 16 will drive the annular frame 3, the annular gear 4, the L-shaped support plate 6, and the potential detector 5 to move up and down together. Therefore, when the potential detector 5 surrounds the potential of the inspection pile, the potential detector 5 can also perform lifting detection. Thus, the potential detector 5 can comprehensively detect the potential at each position around the pile (the potential detector 5 is a prior art, so its working principle will not be elaborated too much in this solution), so as to avoid the occurrence of missed detection parts, which is conducive to comprehensively understanding the operation of the cathodic protection system by measuring the potential values of different parts of the pile, and evaluating the corrosion condition of the structure, the performance of the anti-corrosion system, and the protection effect.
