Description

Technical Field

[0001] The present invention relates to the technical field of wind turbine blade detection, and in particular to a wind turbine blade detection device and a use method thereof. Background Art

The advantages are: the loading mechanism adopted by the present invention can increase the weight of the wind turbine blade by condensing iron sand onto the wind turbine blade with glue, simulating the situation of ice and weight increase of the wind turbine blade caused by cold climate, detecting the influence of weight increase on the service life and durability of the wind turbine blade, and estimating the ultimate durability of the wind turbine blade, making the test more accurate, and the glue can be softened by heating and directly scraped off, without affecting the normal use of the wind turbine blade after the test.

[0003] In the prior art including the above-mentioned patents, only the environment and temperature of the fan blades can be simulated, and the balance and vibration of the fan blades cannot be detected during the environmental simulation and wind simulation. In addition, the imbalance points and vibration points cannot be quickly located during the detection process, which is not conducive to the user's observation of the shortcomings of the fan blades, or the observation point is relatively one-sided and not comprehensive enough. Summary of the invention

[0004] The problem to be solved by the present invention is that the wind turbine blade detection cannot detect vibration and imbalance and cannot quickly find the vibration point and the imbalance point.

[0005] In order to solve the above technical problems, the technical solution of the present invention is: a detection device for blades of wind power generation equipment and a method for using the same, comprising a support seat, a connection shaft is provided on one side of the support seat, a fixing ring is provided on one side of the connection shaft, a machine base is provided on one side of the fixing ring, a machine head is provided on one side of the machine base, and blades are provided on the outer wall of the machine head in a circular array, an observation structure is provided on the support seat, a detection structure is provided on one side of the observation structure, the observation structure can cooperate with the detection structure, and a plurality of inner grooves are provided on the outer wall of the support seat;

[0006] The observation structure includes a shell, the inner wall of the shell is provided with a film, two liquids of different colors are provided in the shell, the film separates the two liquids of different colors, one of the liquids is black and the other is transparent, and a sealing ring passes through one side of the shell.

[0007] Preferably, a slide bar is slidably provided on one side of the sealing ring, a probe is fixedly provided on one side of the slide bar, and through holes are provided on the sides of the probe body and the needle head.

[0008] Preferably, a button is provided on one side of the inner wall of the inner groove, and the button is adapted to the shell. Moving blocks are fixedly provided on the front and back sides of the shell. An outer shell is fixedly provided on the front and back sides of the inner wall of the inner groove, and a slide groove is provided on the back side of the outer shell, and the slide groove is adapted to the moving block.

[0009] Preferably, a cylinder is provided on one side of the shell, one side of the cylinder penetrates the shell and extends to the inside of the shell, and one side of the cylinder is fixedly connected to some phases of the moving block.

[0010] Preferably, a detection ring is rotatably provided on the connecting shaft, and a plurality of through slots are provided on one side of the detection ring, and the through slots are matched with one side of the sliding rod.

[0011] Preferably, the detection structure comprises a spring plate, one side of which is fixedly connected to one side of the sliding rod, and the other side of the spring plate is provided with a detection rod, one side of which is semicircular.

[0012] Preferably, a limit spring is fixedly provided on the front and rear sides of one side of the spring plate, the other side of the limit spring is fixedly connected to one side of the detection ring, a clamping block is provided on the top of the spring plate, and an extrusion block is provided on the top of the clamping block.

[0013] Preferably, a counter is provided on the top of the detection ring, and a force block is provided on one side of the bottom of the counter. The force block is adapted to the extrusion block, and the force block can rotate numbers when it is squeezed by the counter.

[0014] Preferably, a plurality of connecting plates are fixedly provided in a circular array around the outer wall of the detection ring, a rotating ring is slidably provided on one side of the connecting plate, the inner wall of the rotating ring is fixedly connected to the outer wall of the connecting shaft, a fixed ring is rotatably provided inside the rotating ring, a plurality of supporting plates are fixedly provided in a circular array around the outer wall of the fixing ring, a connecting plate is provided on the top of the supporting plate, an anti-slip pad is provided on the bottom of the connecting plate, and a protrusion is provided on one side of the fixing ring.

[0015] S1: When installing the fan blade on the fixed ring for simulated environmental testing, first align the base with the docking plate on the fixed ring, and then insert the base into the docking plate. After insertion, the docking plate and the anti-slip pad will fix the base. After fixation, the user can turn on the wind simulation and perform a rotation test on the fan blade, the machine head and the base. At this time, the fan blade will drive the base to rotate, and the base will drive the fixed ring to rotate along the inner wall of the rotating ring through the fixation of the docking plate. While the fixed ring rotates, the protrusion on one side of the fixed ring will continuously squeeze the detection rod at a uniform speed. After the detection rod is squeezed, it will drive the spring plate to move and compress the limit spring to form two actions;

[0016] S2: The first action is that the spring plate drives the card block to move, and the card block hits the force block through the extrusion block to make the number on the counter jump. The user can quickly know the number of rotations of the fan through the number. The second action is that the spring plate drives the slide bar to move backward, and the slide bar drives the probe to move backward, but the normal movement of the probe will not touch the film, and a safe distance is left between the two. When the fan blades shake during rotation or the rotation is not stable enough and there is an imbalance, the fixing ring will be tilted. After the fixing ring is tilted, the extrusion distance of the protrusion will be increased at the tilted position. At this time, the probe will exceed the safe distance and puncture the film. At this time, the colored liquid set in the probe will enter the transparent liquid behind the film for mixing. The user can observe the position of the first vibration point or imbalance point through the liquid that is damaged first;

[0017] S3: In addition to recording the number of laps and performing vibration and balance tests, users can also perform temperature tests through the liquid in the shell. The fan blades can be tested in a continuous low temperature, but there will be a low temperature warning to avoid damage to the fan blades due to long-term low temperature. In a low temperature environment, the liquid in the shell will freeze as the temperature continues to drop and the low temperature is maintained for a long time, until the long-term low temperature environment causes the liquid in the shell to freeze completely. At this time, the probe will no longer move continuously but will be fixed. At this time, the thrust of the protrusion will act on the entire shell. After the shell is subjected to force, it drives the moving block to move along the shell cylinder to provide buffering. When the shell touches the button, an early warning will be issued, indicating that the fan blades can no longer continue low temperature detection and reminding the user to record the fan blade status in real time.

[0018] Compared with the prior art, the technical solution of the present invention has the following advantages:

[0019] (1) An observation structure is provided on one side of the machine base. The observation structure can detect the balance and vibration of the fan blades in real time during operation through the cooperation between the fixed ring and the sliding rod. When the fan blades are in balanced operation, the two-color liquids in the shell are separated from each other. When the fan blades vibrate or operate unbalanced, the probe inside the shell at the first unbalanced point and the vibration point or the closest point between the two will move. The probe is squeezed to one side to puncture the film and the two-color liquids will mix. By observing and recording the shell at the place where the two-color liquids are mixed first, the priority positions of the unbalanced point and the vibration point can be known. The two-color liquid mixing position can also be located. When the fan blades are vibrating and unbalanced during simulated rotation, the observation structure is also coordinated with the detection structure. The detection structure can trigger the observation structure through the cooperation of the fixed ring to become the power source of the overall linkage. The detection structure can also control the counter to count by the bump hitting the spring plate, so that the user can quickly know the number of rotations of the fan blades, and the vibration or imbalance is generated after how many rotations and how long.

[0020] (2) The two-color liquid in the shell can not only remind the user of fan blade vibration and imbalance, but also provide a low temperature warning for the fan blades during low temperature environment detection, thereby preventing the fan blades from being damaged due to long-term low temperature and affecting the detection data. Long-term low temperature will cause the liquid to condense, and the condensed liquid will fix the probe. At this time, the thrust brought by the protrusion will act on the shell, causing the shell to move backward to trigger the button, so that the user can know the condition of the fan blades. After returning to normal temperature, the liquid will thaw and can continue to be used without replacement and can be reused many times. BRIEF DESCRIPTION OF THE DRAWINGS

A clamping block 706 is provided on the top of the spring plate 703 , and an extrusion block 705 is provided on the top of the clamping block 706 .

[0045] A counter 701 is disposed on the top of the detection ring 10 , and a force block 707 is disposed on one side of the bottom of the counter 701 . The force block 707 is matched with the extrusion block 705 , and the force block 707 can rotate the numbers when it is squeezed by the counter 1 .

[0046] A number of connecting plates 9 are fixedly provided in a circular array around the outer wall of the detection ring 10, a rotating ring 12 is slidably provided on one side of the connecting plate 9, the inner wall of the rotating ring 12 is fixedly connected to the outer wall of the connecting shaft 11, a fixed ring 13 is provided inside the rotating ring 12 for rotation, a number of supporting plates 6 are fixedly provided in a circular array around the outer wall of the fixed ring 13, a connecting plate 2 is provided on the top of the supporting plate 6, an anti-slip pad 15 is provided on the bottom of the connecting plate 2, and a protrusion 14 is provided on one side of the fixed ring 13.

[0047] S1: When the fan blade 5 is installed on the fixing ring 13 for simulated environmental testing, the base 3 is first aligned with the docking plate 2 on the fixing ring 13, and the base 3 is inserted into the docking plate 2 after alignment. After insertion, the docking plate 2 cooperates with the anti-slip pad 15 to fix the base 3. After fixation, the user can turn on the wind simulation, and perform a rotation test on the fan blade 5, the head 4 and the base 3. At this time, the fan blade 5 will drive the base 3 to rotate, and the base 3 will drive the fixing ring 13 to rotate along the inner wall of the rotating ring 12 through the fixation of the docking plate 2. While the fixing ring 13 rotates, the protrusion 14 on one side of the fixing ring 13 will continuously squeeze the detection rod 704 at a uniform speed. After the detection rod 704 is squeezed, it will drive the spring plate 703 to move and compress the limit spring 702 to form two actions;

[0048] S2: The first action is that the spring plate 703 drives the card block 706 to move, and the card block 706 hits the force block 707 through the extrusion block 705 to make the number on the counter 701 jump, and the user can quickly know the number of rotations of the fan through the number. The second action is that the spring plate 703 drives the slide bar 809 to move backward, and the slide bar 809 drives the probe 805 to move backward, but the probe 805 will not touch the film 807 during normal movement, and a safety distance is left between the two. When the fan blade 5 shakes during the rotation process or the rotation is not stable enough and there is an imbalance, it will cause the fixing ring 13 to tilt. After the fixing ring 13 tilts, the squeezing distance of the protrusion 14 will be increased at the tilted position. At this time, the probe 805 will exceed the safety distance and puncture the film 807. At this time, the colored liquid set in the probe 805 will enter the transparent liquid behind the film 807 for mixing. The user can observe the position of the first vibration point or imbalance point through the liquid that is damaged first;

[0049] S3: In addition to recording the number of circles and performing vibration and balance detection, the user can also perform temperature testing through the liquid in the shell 801, and the fan blades 5 can be tested in a continuous low temperature, but there will be a low temperature warning to avoid damage to the fan blades 5 due to the low temperature for too long. In a low temperature environment, the liquid in the shell will freeze as the temperature continues to drop and the low temperature is maintained for a long time, until the long-term low temperature environment causes the liquid in the shell 801 to be completely frozen. At this time, the probe 805 will no longer continue to move but will be fixed. At this time, the thrust of the protrusion 14 will act on the entire shell 801. After the shell 801 is subjected to the force, it drives the moving block 806 to move the cylinder 803 along the shell 808 to provide a buffer. When the shell 801 touches the button 802, an early warning will be issued, indicating that the fan blades 5 can no longer continue to detect at low temperatures and remind the user to record the status of the fan blades 5 in real time.

[0050] The working principle and use process of the present invention are as follows: S1: When the fan blades 5 are installed on the fixing ring 13 for simulated environmental testing, the base 3 is first aligned with the docking plate 2 on the fixing ring 13, and the base 3 is inserted into the docking plate 2 after alignment. After insertion, the docking plate 2 cooperates with the anti-slip pad 15 to fix the base 3. After fixation, the user can turn on the wind simulation, and perform rotation test on the fan blades 5 in conjunction with the head 4 and the base 3. At this time, the fan blades 5 will drive the base 3 to rotate, and the base 3 will drive the fixing ring 13 to rotate along the inner wall of the rotating ring 12 through the fixation of the docking plate 2. While the fixing ring 13 rotates, the protrusion 14 on one side will continuously squeeze at a uniform speed. Detection rod 704, after being squeezed, the detection rod 704 will drive the spring plate 703 to move and compress the limit spring 702 and form two actions. The first action is that the spring plate 703 drives the card block 706 to move, and the card block 706 hits the force block 707 through the squeezing block 705 to make the number on the counter 701 jump. The user can quickly know the number of rotations of the fan through the number. The second action is that the spring plate 703 drives the slide bar 809 to move backward, and the slide bar 809 drives the probe 805 to move backward, but the probe 805 will not contact the film 807 during normal movement. A safe distance is left between the two. When the fan blade 5 shakes or rotates unsteadily during rotation, When the fixing ring 13 is not stable enough and there is an imbalance, the fixing ring 13 will be tilted. When the fixing ring 13 is tilted, the squeezing distance of the protrusion 14 will be increased at the tilted position. At this time, the probe 805 will exceed the safe distance and puncture the film 807. At this time, the color liquid set in the probe 805 will enter the transparent liquid behind the film 807 and mix. The user can observe the position of the first vibration point or imbalance point through the liquid that is damaged first. In addition to the number of circles, vibration and balance detection, the user can also perform temperature testing through the liquid in the shell 801, so that the fan blade 5 can be tested in a continuous low temperature, but there will be a low temperature pre-test. Warning, to avoid damage to the fan blades 5 caused by low temperature for too long. In a low temperature environment, the liquid in the shell will freeze as the temperature continues to drop and the low temperature is maintained for a long time, until the long-term low temperature environment causes the liquid in the shell 801 to be completely frozen. At this time, the probe 805 will no longer continue to move but will be fixed. At this time, the thrust of the protrusion 14 will act on the entire shell 801. After the shell 801 is subjected to the force, it drives the moving block 806 to move the cylinder 803 along the shell 808 to provide a buffer. When the shell 801 touches the button 802, an early warning prompt will be given, and the fan blades 5 can no longer continue low temperature detection and remind the user to record the status of the fan blades 5 in real time.

The second action is that the spring plate (703) drives the slide bar (809) to move backward, and the slide bar (809) drives the probe (805) to move backward, but the probe (805) does not contact the film (807) during normal movement, and a safe distance is left between the two. When the fan blade (5) shakes during rotation or rotates unsteadily and has an unbalanced part, the fixing ring (13) will be tilted. When the fixing ring (13) is tilted, the extrusion distance of the protrusion (14) will be increased at the tilted part. At this time, the probe (805) will exceed the safe distance and pierce the film (807). At this time, the colored liquid set in the probe (805) will enter the transparent liquid behind the film (807) and mix. The user can observe the position of the first vibration point or the unbalanced point through the liquid that is damaged first. S3: In addition to recording the number of laps and performing vibration and balance tests, the user can also perform temperature tests through the liquid in the shell (801), allowing the fan blades (5) to be tested in a continuous low temperature environment. However, there will be a low temperature warning to prevent the fan blades (5) from being damaged by the low temperature for too long. In a low temperature environment, the liquid in the shell will freeze as the temperature continues to drop and the low temperature is maintained for a long time, until the long-term low temperature environment causes the liquid in the shell (801) to be completely frozen. At this time, the probe (805) will no longer move continuously but will be fixed. At this time, the thrust of the protrusion (14) will act on the entire shell (801). After the shell (801) is subjected to the force, it drives the moving block (806) to move the cylinder (803) along the shell (808) to provide a buffer. When the shell (801) touches the button (802), an early warning will be issued, indicating that the fan blades (5) can no longer continue to be tested at low temperatures and reminding the user to record the status of the fan blades (5) in real time.
