Description

Technical Field

[0001] The invention belongs to the technical field of wind power and relates to a conductive suction cup. Background Art

[0002] With the development and maturity of our wind power technology, my country has planned a large number of wind power bases on land and in coastal areas. Lightning is one of the most important natural disasters that cause damage to wind turbines. Relevant research data shows that wind turbine blade damage accounts for about 20%-28% of the total, and electromechanical control systems account for about 70.5%-71%.

[0003] Wind turbines are usually installed in areas with high geographical locations. Due to the lack of other tall objects around them, they are more likely to attract lightning. The size of the lightning protection grounding resistance of the wind turbine is directly related to the safe and stable operation of the wind turbine. The wind turbine blades are the most vulnerable parts of the wind turbine. Its good lightning protection design is the decisive factor in ensuring the continuous and stable operation of the wind turbine. When lightning strikes, it is received by the lightning rod, then transmitted to the main engine downconductor system through the blade downconductor system, and finally guided into the ground.

[0004] Since the wind turbine is about 100 meters above the ground and the blade tip is close to 100 meters from the nacelle, the grounding resistance of the lightning protection grounding circuit cannot be directly measured after the wind turbine is installed. At present, the grounding inspection of the grounding resistance of the lightning protection grounding circuit of the wind turbine is a segmented inspection. That is: (1) The resistance measurement between the blade lightning rod and the blade root flange is to check whether the blade lightning protection down conductor connection is intact and whether the lightning protection down conductor cross section is damaged before the blade is hoisted, and to detect the DC resistance between the blade lightning rod and the blade root flange. (2) The resistance measurement between the variable pitch bearing and the tower grounding electrode is to check the integrity of the lightning discharge device (carbon brush, slip ring, discharge gap, etc.) on the variable pitch bearing, main bearing, and yaw bearing before and after the unit is hoisted, and confirm that the tower jumper connection is reliable. Moreover, the grounding resistance of the lightning protection grounding circuit cannot be directly detected after the wind turbine is in operation. The surface of the blade lightning rod is flat and there is no terminal for applying test voltage. Therefore, it is urgently needed to propose a conductive suction cup. The suction force of the suction cup can make the conductor of the suction cup tightly connected with the lightning rod on the blade. The lead-out terminal on the back of the suction cup acts as a wiring terminal to solve the problem that the test voltage cannot be directly applied to the blade lightning rod. However, no similar conductive suction cup is provided in the prior art. Summary of the invention

[0005] The purpose of the present invention is to overcome the disadvantages of the prior art and provide a conductive suction cup, which can solve the problem that the lightning arrester of the wind turbine blade cannot directly apply the test voltage.

[0006] To achieve the above-mentioned purpose, the conductive suction cup described in the present invention includes a suction cup body, which includes a suction cup bottom plate and a suction cup skirt arranged on the outside of the suction cup bottom plate, the outer end surface of the suction cup bottom plate is connected to the suction cup skirt, a conductive ring is arranged on the front side of the suction cup bottom plate, the lead-out terminal passes through the suction cup bottom plate and is connected to the conductive ring, and a conduit passes through the suction cup bottom plate.

[0007] The conductive ring is sleeved on the catheter.

[0008] The suction cup bottom plate is provided with a lighting hole and a camera hole, wherein a lighting lamp is installed in the lighting hole, and a camera is installed in the camera hole.

[0009] The lighting holes and the camera holes are on the same circumference, and the lighting holes and the camera holes are staggered in sequence, and the lighting holes and the camera holes are evenly distributed along the circumference.

[0010] The end surface of the conductive ring is higher than the suction cup support bar and the guide tube.

[0011] The suction cup body is made of soft rubber integrally cast.

[0012] The conductive ring and the lead-out terminal are made of copper conductive material.

[0013] The conduit is of a strong insulating material.

[0014] The conductive suction cup described in the present invention includes a suction cup body, which includes a suction cup bottom plate and a suction cup skirt arranged on the outside of the suction cup bottom plate, the outer end surface of the suction cup bottom plate is connected to the suction cup skirt, a conductive ring is arranged on the front side of the suction cup bottom plate, the lead-out terminal passes through the suction cup bottom plate and is connected to the conductive ring, a catheter passes through the suction cup bottom plate, a lighting hole and a camera hole are arranged on the suction cup bottom plate, a lighting lamp is installed in the lighting hole, a camera is installed in the camera hole, the lighting holes are evenly distributed along the circumference, and the camera holes are evenly distributed along the circumference.

[0015] The number of the lighting holes is three; the number of the camera holes is three.

[0016] The present invention has the following beneficial effects:

[0017] During specific operation of the conductive suction cup described in the present invention, under the action of the lighting fixture in the lighting hole and the camera in the camera hole, the wind turbine blade lightning receptor is aligned with the conductive ring, the suction cup skirt is attached to the blade, and the gas in the suction cup is extracted by a catheter, so that the conductive ring of the suction cup and the lightning receptor on the blade are tightly connected and in good contact. At this time, the lead-out terminal acts as a wiring terminal, thereby solving the problem that the wind turbine blade lightning receptor cannot directly apply a test voltage.
