Description

Technical Field

[0001] This utility model relates to the field of phased array monitoring technology, and in particular to an instrument for detecting high-strength bolts of wind turbine generator sets using a phased array. Background Technology

[0002] In the field of wind power generation, wind turbine generators, as the core equipment for converting wind energy into electrical energy, are crucial for their safe and stable operation. High-strength bolts, as key connecting components in wind turbine generators, play a vital role in connecting important structures such as the tower, blades, and hub. The reliability of their connection directly affects the performance and lifespan of the entire wind turbine generator.

[0003] Phased array testing technology, as an advanced non-destructive testing method, boasts advantages such as high detection accuracy, intuitive imaging, and the ability to inspect complex-shaped workpieces. It has been widely applied in the inspection of high-strength bolts for wind turbine generators. Phased array testing instruments can accurately detect internal defects such as cracks and porosity in high-strength bolts, thereby promptly identifying potential safety hazards and ensuring the safe operation of wind turbine generators.

[0004] However, existing phased array instruments for inspecting high-strength bolts in wind turbine generators present numerous inconveniences during use. Currently available instruments typically require manual handling and must be stored in a separate case. During use, the instrument must be completely removed from the case to perform the inspection; it cannot be operated directly from inside the case. This not only increases the operator's workload but also wastes a significant amount of time during frequent removal and storage, reducing the efficiency of the inspection work. Utility Model Content

[0005] The purpose of this invention is to disclose an instrument for testing high-strength bolts in wind turbine generator sets using a phased array. This achieves the dual goals of convenient operation and safety protection.

[0006] To achieve the above objectives, this utility model discloses an instrument for detecting high-strength bolts of wind turbine generator sets using a phased array, comprising: an instrument body; a base having an upwardly inclined opening; a cover hinged to the base for covering or opening the opening; a lock structure including an unlocking drive unit and a locking latching unit, the locking latching unit being fixedly connected to the base and located on both sides of the opening; the unlocking drive unit being rotatably connected to the cover corresponding to the locking latching unit, and when the cover covers the opening, the unlocking drive unit and the locking latching unit engage and lock; and a drive member, one end of which is hinged to the base and the other end to the cover, and when the unlocking drive unit and the locking latching unit are disengaged from the locked state, the drive member provides a force to the cover away from the opening.

[0007] By adopting the above solution, a base with an upwardly tilted opening and a cover hinged to the base are designed. This design allows the cover to conceal the opening and protect the internal structure of the instrument when it is stored; and when needed, the instrument does not need to be completely removed from the case. Through the cooperation of the unlocking drive unit and the locking latch unit, when the unlocking drive unit and the locking latch unit are disengaged, the drive component provides a force away from the opening to the cover, achieving an automatic opening effect after unlocking. The operator only needs to perform a simple unlocking operation from outside the case, and the cover will automatically open to expose the instrument, facilitating direct testing operations. This greatly saves time in taking out and storing the instrument, improves the efficiency of testing work, and solves the problems of inconvenience and time waste in the use of existing instruments. It also effectively prevents the cover from accidentally opening due to shaking or collision during transportation and storage, thereby protecting the instrument from damage, improving the safety and service life of the instrument, and overcoming the deficiency of existing instruments lacking safety protection mechanisms during storage.

[0008] Furthermore, the unlocking drive unit includes a toggle member rotatably connected to the surface of the cover. The toggle member has a pull groove on the side facing out of the cover, and a drive rod that rotates synchronously with the toggle member on the side facing inward of the cover. The end of the drive rod is used to engage with the locking latching unit.

[0009] By adopting the above scheme, when unlocking is required, the operator only needs to place their finger in the slot to conveniently and comfortably apply force to the actuating element, easily rotating it to trigger the unlocking action. A drive rod that rotates synchronously with the actuating element on the side facing the cover is provided. This synchronous rotation design ensures the consistency of movement between the actuating element and the drive rod. When the operator rotates the actuating element, the drive rod rotates precisely at the same angle and direction, ensuring that the end of the drive rod can accurately engage or disengage with the locking unit. This stable motion transmission relationship avoids unlocking failures caused by asynchronous movement between components, improving the reliability and stability of the entire unlocking drive unit. The slot design not only facilitates operation but also, to a certain extent, prevents accidental operation. Because the slot requires the operator to actively place their finger in to apply force, slight collisions or accidental touches will not cause the actuating element to rotate, thus preventing accidental unlocking of the instrument. This is crucial for ensuring the safety of the instrument during transportation and storage, effectively preventing damage to the instrument caused by accidental unlocking.

[0010] Furthermore, the end of the drive rod is provided with a bent section and a snap-fit ​​section. The bent section is used to drive the snap-fit ​​section to rotate circumferentially along the drive rod when the drive rod rotates.

[0011] By adopting the above scheme, the design of the bending section cleverly alters the direction of force transmission and the trajectory of motion. When the unlocking drive unit is operating, as the actuating element rotates the drive rod, the bending section converts this rotation into circumferential movement of the locking section along the drive rod. When locking is required, the locking section can accurately move to the position corresponding to the locking unit, achieving a secure lock and ensuring a tight seal between the cover and the base, preventing accidental opening of the instrument when not in use and protecting the safety of internal components. Conversely, during unlocking, the locking section can quickly and accurately disengage from the locking unit, allowing the cover to open automatically under the action of the drive element, providing a convenient user experience. The bending section design helps to disperse stress, reducing localized stress concentration during repeated locking and unlocking. In long-term unlocking and locking operations, the locking section will withstand significant friction and impact forces; without a reasonable stress dispersion design, this can easily lead to wear or fatigue fracture of the locking section. The presence of the bending section can distribute stress evenly at the end of the drive rod, reducing the wear of the locking section, extending the service life of the locking section, and thus improving the durability of the entire unlocking drive unit.

[0012] Furthermore, a torsion spring is provided between the actuating element and the cover to provide a resetting force for the actuating element.

[0013] By adopting the above solution, the torsion spring provides a restoring force to the actuating element, making unlocking and locking operations more convenient and smooth. During unlocking, the operator only needs to overcome the initial spring force of the torsion spring to actuate the element. After completing the unlocking action, releasing the hand allows the actuating element to automatically return to its initial position under the action of the torsion spring. During unlocking and locking operations, the automatic restoring function of the torsion spring allows the actuating element to quickly return to a safe position, reducing the time the operator is in contact with the actuating element and lowering the probability of accidents such as finger injuries due to accidental movement of the actuating element, thus providing more reliable safety for the operator.

[0014] Furthermore, the locking snap-fit ​​unit includes a first inclined surface and a second snap-fit ​​surface, wherein the first inclined surface is used to provide a guiding force for the snap-fit ​​segment to slide toward the second snap-fit ​​surface when the cover is closed.

[0015] By employing the above scheme, the first inclined surface plays a crucial guiding role during the lid's closing process. When the operator closes the lid towards the base, the locking segment first contacts the first inclined surface. Due to the specific angle of inclination of the first inclined surface, it provides a clear and smooth guiding force to the locking segment, allowing it to slide smoothly along the inclined surface and gradually approach the second locking surface. This precise guidance avoids jamming, misalignment, or collisions during the closing process, ensuring that the lid closes easily and accurately, greatly improving the smoothness and convenience of operation.

[0016] Furthermore, the second snap-fit ​​surface is provided with a snap-fit ​​groove, which snaps into the snap-fit ​​segment.

[0017] By adopting the above scheme, the slot provides a clear and unique engagement position for the engagement segment. During the closing process of the cover, the first inclined surface guides the engagement segment to slide towards the second engagement surface. When the engagement segment approaches the second engagement surface, the edge of the slot can further guide the engagement segment into the slot with greater precision. This dual guidance mechanism ensures that the engagement segment can accurately engage with the slot, avoiding problems such as weak engagement or inability to engage due to positional deviations, and greatly improving the accuracy of engagement.

[0018] Furthermore, a first hinge seat is provided inside the base, and a second hinge seat is provided inside the cover. The first hinge seat is hinged to one end of the driving member, and the second hinge seat is hinged to the other end of the driving member.

[0019] By adopting the above scheme, the cover can rotate flexibly around the hinge point through the hinges of the first and second hinge seats to both ends of the drive component. This design allows the cover to open and close at different angles according to actual needs. For example, during the testing process, the operator may need to open the cover to a suitable position based on the position of the bolts and the testing angle to facilitate instrument operation and testing. The hinge structure provides this flexible adjustment capability, improving the instrument's ease of operation and applicability.

[0020] Furthermore, the hinge opening angle between the cover and the base is 0-120°.

[0021] By adopting the above solution, the 0° closed state ensures a tight fit between the cover and the base, forming a good sealing environment. The 120° wide opening range provides ample operating space for the operator. When performing high-strength bolt testing, operators may need to place testing probes, cables, and other equipment inside the instrument or perform debugging and installation. The wide-angle opening of the cover allows operators to more easily reach into the instrument to perform various operations, reducing operational difficulties and errors caused by limited space and improving work efficiency. In addition, when the instrument requires maintenance, the wide opening also facilitates the inspection, cleaning, and replacement of internal components.

[0022] Furthermore, a carrying handle is provided on the outside of the base.

[0023] By adopting the above approach, wind turbine generators are typically distributed over a relatively wide area, and there may be some distance between different generators and between different testing points within a generator. The portable device allows operators to easily lift the instrument and quickly move it between different locations. For example, when it is necessary to inspect the high-strength bolts of multiple wind turbine generators in the same wind farm, operators can use the portable device to carry the instrument from one generator to another without the need for other transport tools, greatly improving the efficiency of the testing work.

[0024] Furthermore, the driving component is either a hydraulic cylinder or a pneumatic cylinder.

[0025] By adopting the above scheme, both the hydraulic cylinder and the pneumatic cylinder can generate a large thrust or pull force to meet the power requirements for opening and closing the instrument cover. This eliminates the need for electricity and ensures that the cover moves at a uniform speed and smoothly during the opening and closing process.

[0026] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0027] 1. Traditional instruments require complete removal from the case for use, which is cumbersome. However, with this invention, when the instrument is stored, the operator does not need to remove the entire instrument from the case. A simple operation on the unlocking drive unit outside the case triggers the unlocking mechanism, causing the cover to open automatically and revealing the instrument. This greatly simplifies the operation and reduces the difficulty of operation.

[0028] 2. It eliminates the tedious process of frequently taking out and putting away traditional instruments, allowing operators to quickly start the instrument for testing and quickly put it away after testing. In scenarios requiring the testing of a large number of high-strength bolts on wind turbine generators, this time saving can significantly improve overall testing efficiency and shorten the testing cycle.

[0029] 3. During transportation and storage, the locking mechanism can securely lock the cover to the base, effectively preventing the cover from being accidentally opened due to external forces such as shaking or collision. This avoids exposing the internal components of the instrument, reduces the risk of damage due to accidental collisions, and ensures the safety of operators and the surrounding environment.

[0041] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0042] Please refer to Embodiment 1 of this utility model. Figures 1 to 4As shown, an instrument for detecting high-strength bolts in wind turbine generator sets using a phased array is provided. The instrument includes a main body, a base 1, a cover 2, a locking structure 3, and a drive component 4. The overall design of the instrument is compact and reasonable, with each component working in concert to achieve the dual goals of convenient operation and safety protection, effectively improving the detection efficiency and safety of high-strength bolts in wind turbine generator sets. Specifically, the base 1, as the supporting component of the instrument, is made of high-strength, corrosion-resistant materials, such as aluminum alloy or stainless steel, to ensure long-term stable use in the harsh environment of wind farms. The base 1 has an upwardly inclined opening 11, the inclination angle of which is carefully designed, generally between 30° and 60°. This facilitates the opening and closing of the cover 2 and creates a good seal when the cover 2 is closed, preventing dust, moisture, etc., from entering the instrument. A first hinge seat 5 is provided inside the base 1 for hinged connection to one end of the drive component 4. The first hinge seat 5 is firmly fixed inside the base 1 by bolts or welding, ensuring that the drive component 4 can withstand the corresponding force without loosening during operation. The cover 2 is also made of high-strength material and matches the base 1. The cover 2 and base 1 are hinged together by a stainless steel hinge, which has good wear resistance and corrosion resistance. The hinge opening angle between the cover 2 and base 1 is 0-120°. Through reasonable hinge design and installation position, the cover 2 can rotate flexibly and smoothly within this angle range. A second hinge seat 6 is provided inside the cover 2 for hinged connection to the other end of the drive component 4. The structure and fixing method of the second hinge seat 6 are similar to the first hinge seat 5, ensuring the stability of the connection. In this embodiment 1, the inclination angle of the opening 11 is 60°, and the hinge opening angle between the cover 2 and base 1 is 90°.

[0043] In some embodiments, the lock body structure 3 includes an unlocking drive unit 31 and a locking latching unit 32. The locking latching unit 32 is fixedly connected to the base 1 and located on both sides of the opening 11. The unlocking drive unit 31 is rotatably connected to the cover 2 corresponding to the locking latching unit 32. In this embodiment 1, the unlocking drive unit 31 includes an actuating member 311 rotatably connected to the surface of the cover 2. The actuating member 311 is made of engineering plastic and has a certain strength and toughness. A groove 312 is provided on the side of the actuating member 311 facing outward from the cover 2. The groove 312 is arc-shaped with moderate depth and width, making it convenient for the operator to insert their fingers to apply force. A drive rod 313 is provided on the side of the actuating member 311 facing inward from the cover 2 and rotates synchronously with it. The drive rod 313 is made of metal, such as stainless steel, and is tightly connected to the actuating member 311 by bolts or buckles to ensure that the two rotate synchronously. The drive rod 313 has a bent section 3131 and a locking section 3132 at its end. The angle of the bent section 3131 is 90°-120°, and its function is to convert the rotation of the drive rod 313 into the circumferential movement of the locking section 3132 along the drive rod 313. The locking section 3132 is cylindrical or square in shape, and its surface is smoothed to reduce friction with the locking unit 32. A torsion spring 314 is provided between the actuating element 311 and the cover 2. One end of the torsion spring 314 is fixed to the actuating element 311, and the other end is fixed to the cover 2. The elastic force of the torsion spring 314 is precisely calculated and adjusted to provide sufficient restoring force for the actuating element 311 without making the operator feel too much effort when actuating the actuating element 311. The locking unit 32 is fixedly connected to the base 1 and is located on both sides of the opening 11. The locking latching unit 32 is a triangular prism, including a first inclined surface 321 and a second latching surface 322. The inclination angle of the first inclined surface 321 is 15°-30°, and its function is to provide a guiding force for the latching section 3132 to slide towards the second latching surface 322 when the cover 2 is closed. The second latching surface 322 is provided with a latching groove 323, the shape and size of which match the latching section 3132 to ensure that the latching section 3132 can be accurately and firmly latched into the latching groove 323. When the cover 2 covers the opening 11, the unlocking drive unit 31 and the locking latching unit 32 engage and lock.

[0044] In some embodiments, the driving component 4 is either a hydraulic cylinder or a pneumatic cylinder. Both hydraulic and pneumatic cylinders can generate significant thrust or pull force to meet the power requirements for opening and closing the instrument cover 2. This requires no electricity and ensures that the cover 2 moves at a uniform speed and smoothly during opening and closing. In this embodiment, a pneumatic cylinder is used as an example. The pneumatic cylinder has good performance and reliability. One end of the cylinder is hinged to the first hinge seat 5 inside the base 1 via a pin, and the other end is hinged to the second hinge seat 6 inside the cover 2 via a pin. The stroke of the cylinder is rationally selected based on the opening and closing angle of the cover 2 and the overall dimensions of the instrument, ensuring that when the unlocking drive unit 31 and the locking latching unit 32 are disengaged, the cylinder can provide sufficient force to the cover 2, allowing the cover 2 to open smoothly to the required angle.

[0045] In some embodiments, a carrying device 7 is provided on the outside of the base 1. The carrying device 7 is made of high-strength nylon material, which has a certain degree of flexibility and wear resistance. The carrying device 7 is fixed to both sides of the base 1 by metal rings or bolts, which is secure and can bear the weight of the instrument. The length and width of the carrying device 7 are designed according to ergonomic principles to facilitate the operator's grip and reduce fatigue from carrying the instrument for a long time.

[0046] In the stored state, the cover 2 covers the opening 11 of the base 1, the actuating element 311 of the unlocking drive unit 31 is in its initial position, and the locking section 3132 of the drive rod 313 engages in the slot 323 of the locking unit 32, thus securing the cover 2 to the base 1. At this time, the internal components of the instrument are well protected, preventing damage during transportation and storage. When the instrument needs to be used for testing, the operator simply places their finger into the pull groove 312 of the actuating element 311 and pushes the actuating element 311 against the elastic force of the torsion spring 314. The actuating element 311 drives the drive rod 313 to rotate, and the bending section 3131 converts the rotation of the drive rod 313 into the circumferential movement of the locking section 3132 along the drive rod 313, causing the locking section 3132 to disengage from the slot 323 of the locking unit 32. Simultaneously, the cylinder extends under internal air pressure, providing a force to the cover 2 away from the opening 11, causing the cover 2 to automatically open around the hinge until it reaches the predetermined opening angle, such as 90°. At this point, the instrument body is exposed, allowing the operator to easily perform testing operations.

[0047] After the test is completed, the operator manually closes the cover 2 towards the base 1. During the closing process, the locking segment 3132 first contacts the first inclined surface 321 of the locking unit 32. The first inclined surface 321 provides a guiding force for the locking segment 3132 to slide towards the second locking surface 322, allowing the locking segment 3132 to slide smoothly along the inclined surface. When the locking segment 3132 approaches the second locking surface 322, the edge of the locking groove 323 further guides the locking segment 3132 into the groove 323, achieving locking. At the same time, the actuating element 311 automatically returns to its initial position under the action of the torsion spring 314, completing the locking of the cover 2 and the base 1, and the instrument returns to its stored state.

[0048] In some embodiments, to further enhance security, a keyhole can be provided on the toggle member 311, so that the unlocking effect can only be triggered by a key, thereby allowing the pull groove 312 to be pulled. The specific structure is not limited, as long as it can achieve the above-mentioned functions.

[0049] It should be noted that, due to the different specific structures of the instrument body, it is not shown in the figures of this application. In actual use, a foam shock-absorbing plate is provided between the base 1 and the instrument body. Different foam shock-absorbing plates can be adapted according to different instrument structures, thus making the base 1 universal and improving the safety of storing the instrument body.

[0050] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0051] 1. Traditional instruments require complete removal from the case for use, which is cumbersome. However, with the instrument of this invention, when stored, the operator does not need to remove the entire instrument from the case. A simple operation on the unlocking drive unit 31 from outside the case is sufficient to trigger the unlocking mechanism, causing the cover 2 to open automatically and revealing the instrument body. This greatly simplifies the operation steps and reduces the difficulty of operation.

[0052] 2. It eliminates the tedious process of frequently taking out and putting away traditional instruments, allowing operators to quickly start the instrument for testing and quickly put it away after testing. In scenarios requiring the testing of a large number of high-strength bolts on wind turbine generators, this time saving can significantly improve overall testing efficiency and shorten the testing cycle.

[0053] 3. During transportation and storage, the locking structure 3 can firmly lock the cover 2 onto the base 1, effectively preventing the cover 2 from being accidentally opened due to external forces such as shaking or collision, avoiding the exposure of internal components of the instrument, reducing the risk of damage due to accidental collision, and ensuring the safety of operators and the surrounding environment.

[0054] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
