Description

Technical Field

[0001] This invention relates to the field of wind power engineering technology, and more specifically, to a safety testing device for wind power engineering equipment. Background Technology

[0002] As a highly efficient, clean, and green new energy source, wind power equipment continues to enjoy high prosperity under the dual-carbon strategy. Wind power projects still have huge development potential. my country's grid-connected wind power capacity exceeds 340 million kilowatts, and the number of wind turbine units in operation exceeds 170,000. Wind turbine units continue to develop rapidly towards larger size, taller towers, and longer blades. However, this is accompanied by safety maintenance and inspection issues for wind power engineering equipment.

[0003] Because wind turbines are tall structures with low natural frequencies that are close to the frequency of pulsating wind, they are prone to resonance, which can easily lead to cracks and damage to the turbine shaft. This can also cause large displacements and damage to the structure. Currently, many safety maintenance and inspections of wind power equipment still rely on manual climbing of the turbine for high-altitude work. This not only poses danger to the workers themselves but also results in low inspection efficiency and makes it impossible to conduct real-time inspections and repairs for uncertain cracks and damage to the turbine shaft. Summary of the Invention

[0004] The purpose of this invention is to provide a safety inspection device for wind power generation engineering equipment to solve the problems mentioned in the background art: because wind turbines are tall structures with low natural frequencies that are close to the frequency of pulsating wind, they are prone to resonance, which can easily lead to cracks and damage to the turbine shaft and potentially cause large displacements that damage the structure.

A positioning ring groove 78 is provided in the lower half of the movable circular groove 72, and a camera device 75 is located between the positioning ring groove 78 and the main body disk 71.

The internal vibration frequency detector 76 is directly above the connection hole 44 opened on the bottom surface of the control box 41. During the overall upward movement of the inspection device 7, when the inspection device 7 rises to the highest point of the fan rod 2, the internal vibration frequency detector 76 will be inserted into the connection hole 44 to detect the vibration frequency of the control box 41. During the overall downward movement of the inspection device 7, when the inspection device 7 falls to the lowest point of the fan rod 2, the positioning ring groove 78 will combine with the upper half of the hollow connecting shaft 13 to limit the movement of the inspection device 7.

[0036] As a further aspect of the present invention: a fixed toothed groove 7701 is provided on the inner wall of the outer ring of the annular groove cavity 77, and a movable toothed groove 7703 is installed on the inner wall of the inner ring of the annular groove cavity 77. The movable toothed groove 7703 is movably embedded in the outer wall of the upper half of the movable circular groove 72. An inner ring track 7702 is formed between the movable toothed groove 7703 and the fixed toothed groove 7701, and a camera device 75 is connected between the movable toothed groove 7703 and the fixed toothed groove 7701. The movable toothed groove 7703 can rotate within the movable circular groove 72, while the fixed toothed groove 7701 is fixedly installed in the inner wall of the outer ring of the annular groove cavity 77. A moving gear 7502 is connected between the fixed toothed groove 7701 and the movable toothed groove 7703. The design of the fixed toothed groove 7701 and the movable toothed groove 7703 provides a motion basis for the camera device 75 to achieve forward and reverse rotation.

[0037] As a further aspect of the present invention: a high-definition camera 7501 is provided at the top of the camera device 75, and a rotating shaft 7503 is connected to the lower end of the high-definition camera 7501. A movable gear 7502 is fixedly provided on the rotating shaft 7503, and the movable gear 7502 is meshed between the movable tooth groove 7703 and the fixed tooth groove 7701. The rotating shaft 7503 passes through the inner ring track 7702, and a drive motor 7504 is connected to the bottom of the rotating shaft 7503. The drive motor 7504 is connected to another drive motor 7504. The drive motor 7504 is a reversible motor, and the drive motor 7504 drives the moving gear 7502 to rotate through the rotating shaft 7503. The rotating moving gear 7502 will make forward and reverse circular motions along the fixed tooth groove 7701 and the inner ring track 7702, which will drive the high-definition camera 7501 to make forward and reverse circular motions. By utilizing the ingenious connection between the camera device 75 and the ring groove cavity 77, the high-definition camera 7501 can rotate around the fan rod 2 to shoot and detect the surface cracks and damage of the fan rod 2.

[0038] As a further embodiment of the present invention: the limiting ring 74 includes a connecting block 7402 and a connecting block 7403 that are fixedly connected to the main body disk 71. The outer end of the connecting block 7402 is fixedly connected to an outer ring track 7401. The connecting block 7403 is connected to the bottom of the camera device 75, and a track moving guide rod 7404 is connected to the upper surface of the connecting block 7403. The track moving guide rod 7404 passes through the outer ring track 7401, and a limiting ball 7405 is provided at the bottom of the track moving guide rod 7404. The connecting block 7403 is specifically connected to the outer surface of the drive motor 7504 at the lower end of the camera device 75. While the drive motor 7504 drives the high-definition camera 7501 to rotate, the drive motor 7504 will rotate around the outer ring track 7401 under the action of the limiting ring 74, which effectively improves the stability of the drive motor 7504 when it moves.

[0039] Specifically, in inspecting the fan rod 2 itself, a quality inspection device 7 installed on the fan rod 2 is used. A drive motor 7504 connected to a rotating shaft 7503 drives a moving gear 7502 to rotate. The rotating gear 7502 rotates along a fixed tooth groove 7701 and an inner ring track 7702, causing the high-definition camera 7501 to rotate around the fan rod 2. Simultaneously, while the drive motor 7504 drives the high-definition camera 7501 to rotate, the drive motor 7504, under the action of a limiting ring 74, rotates around an outer ring... The rotation of track 7401 effectively improves the stability of drive motor 7504 during movement. During the rotation of high-definition camera 7501, the high-definition camera 7501 will record the surface condition of wind turbine rod 2 in real time. When cracks or damage are detected on the surface of wind turbine rod 2, the high-definition camera 750 will send a maintenance alarm to the wind turbine management organization via remote signal to remind staff to repair in time. However, in order to inspect the entire wind turbine rod 2, the quality inspection device 7 also needs to move up and down. Therefore, the following solution is provided.

[0040] As a further embodiment of the present invention: the lifting device 3 includes a drive electrical box 31 fixedly installed on the upper surface of the landing block 11 and a lower limit block 32 fixedly installed on the upper surface of the connecting block 61. The lower limit block 32 is connected to a threaded rod 33, which passes through the connecting block 61 and is connected to the drive electrical box 31. An upper limit block 34 is movably connected to the top of the connecting block 61. The threaded rod 33 is movably connected to the lower limit block 32 and the connecting block 61, and the connection is smooth without threads. The upper limit block 34 is fixedly installed on the bottom surface of the control box 41. In addition, the threaded rod 33 is connected to the quality inspection device 7. The drive electrical box 31 can drive the threaded rod 33 to rotate, thereby causing the quality inspection device 7 to move up and down along the threaded rod 33, providing a way for the quality inspection device 7 to move.

[0041] As a further embodiment of the present invention: the fan control device 4 includes a control box 41 that runs through the top of the fan rod 2. An external vibration detector 42 is fixedly connected to the upper surface of the control box 41, and a control sensor 43 is fixedly installed at the tail end of the control box 41. A connection hole 44 is provided on the bottom surface of the control box 41. The external vibration detector 42 is used to detect the vibration frequency of the fan as a whole under natural conditions. The connection hole 44 is combined with the internal vibration frequency detector 76 to detect the vibration frequency generated by the motor running inside the control box 41. The control sensor 43 can receive the detection data from the internal vibration frequency detector 76 and the external vibration detector 42, and adjust the speed of the gearbox inside the control box 41 as needed. Through the cooperation of the external vibration detector 42, the internal vibration frequency detector 76 and the control sensor 43, the internal and external vibration frequencies of the fan can be effectively detected in real time, and then effectively adjusted to prevent resonance at the same frequency, which would cause instability of the fan rod 2, the fan fan 5 and the fan connecting base 6.

[0042] Specifically, to achieve the vertical movement of the quality inspection device 7, it needs to be combined with the lifting device 3. The drive box 31 of the lifting device 3 can drive the threaded rod 33 to rotate, thereby causing the quality inspection device 7 to move up and down along the threaded rod 33. This provides a way for the quality inspection device 7 to move. As the quality inspection device 7 rises as a whole, when it reaches the highest point of the fan rod 2, the internal vibration frequency detector 76 will be inserted into the connection hole 44 to detect the vibration frequency of the control box 41. This is combined with the vibration frequency detected by the external vibration detector 42 under natural conditions. The vibration frequency of the pulsating wind under the state is controlled by the control sensor 43, which receives detection data from the internal vibration frequency detector 76 and the external vibration detector 42. The control sensor 43 adjusts the speed of the gearbox inside the control box 41 according to specific needs to prevent resonance at the same frequency, which would cause instability of the fan rod 2, the fan 5 and the fan connecting base 6. On the other hand, as the quality inspection device 7 descends as a whole, when the quality inspection device 7 reaches the lowest point of the fan rod 2, the positioning ring groove 78 will combine with the upper half of the hollow connecting shaft 13 to limit the movement of the quality inspection device 7.

[0043] The specific working principle of this invention is as follows: When designing the wind turbine generator, a wind turbine fixing base 1 and a wind turbine connecting base 6 are provided for structural reinforcement in its connection with the ground. On the one hand, the landing block 11 is firmly connected to the ground by connecting screws 12. In addition, a connecting block 61 is fixedly connected to the upper end of the landing block 11 by structural steel bars 63, and the connecting block 61 itself is provided with a reinforcing cable 62 for reinforced connection with the ground. Thus, the stability of the wind turbine generator itself is enhanced in the structural design. As for the inspection of the wind turbine rod 2 itself, a quality inspection device 7 installed on the wind turbine rod 2 is used, which is driven by a drive motor 7504 connected to a rotating shaft 7503. Gear 7502 rotates, and the rotating gear 7502 moves in a circular motion along the fixed tooth groove 7701 and the inner ring track 7702, thereby driving the high-definition camera 7501 to rotate around the fan rod 2. Simultaneously, while the drive motor 7504 drives the high-definition camera 7501 to rotate, the drive motor 7504 also rotates around the outer ring track 7401 under the action of the limit ring 74, effectively improving the stability of the drive motor 7504 during movement. During the rotation of the high-definition camera 7501, the high-definition camera 7501 will record the surface condition of the fan rod 2 in real time. When cracks or damage are detected on the surface of the fan rod 2, the high-definition camera 7501 will... A maintenance alarm is sent to the wind turbine management organization via remote signal to remind staff to perform timely maintenance. However, to perform full-body inspection of the wind turbine shaft 2, the quality inspection device 7 needs to be able to move up and down. Therefore, the following solution is provided: to achieve the up and down movement of the quality inspection device 7, the quality inspection device 7 needs to be combined with the lifting device 3. The drive box 31 of the lifting device 3 can drive the threaded rod 33 to rotate, thereby causing the quality inspection device 7 to move up and down along the threaded rod 33. This provides a way for the quality inspection device 7 to move. As the quality inspection device 7 rises as a whole, when the quality inspection device 7 reaches the highest point of the wind turbine shaft 2, the internal vibration frequency detector 76 will be inserted into the connection hole. In the eye 44, the vibration frequency of the control box 41 is detected and controlled. Combined with the vibration frequency of the pulsating wind under natural conditions detected by the external vibration detector 42, and the control sensor 43 receives the detection data from the internal vibration frequency detector 76 and the external vibration detector 42, the operating speed of the gearbox inside the control box 41 is adjusted according to specific needs to prevent resonance of the same frequency from causing instability of the fan rod 2, the fan 5 and the fan connecting base 6. On the other hand, as the quality inspection device 7 descends as a whole, when the quality inspection device 7 reaches the lowest point of the fan rod 2, the positioning ring groove 78 will combine with the upper half of the hollow connecting shaft 13 to limit the movement of the quality inspection device 7.
