Technical Field

[0001] The utility model relates to the technical field of wind turbines, in particular to a wind turbine generator set measuring device. Background Art

[0002] When assembling the transmission chain of a wind turbine with elastic support for the gearbox, it is necessary to adjust the height of the elastic support and ensure that the height of the upper and lower elastic bodies is within the required range. During this process, the height of the upper and lower elastic bodies needs to be measured. The measuring tool currently used is an ordinary vernier caliper, which uses the inner measuring claws on the back of the vernier caliper to clamp the gearbox torque arm and the top / bottom plate to measure the height of the upper and lower elastic bodies. However, the contact area of ​​the inner measuring claws of the vernier caliper is small and the vernier caliper is long, so it is impossible to ensure that the vernier caliper is perpendicular to the measured surface, resulting in difficult measurement and large errors. When the vernier caliper is clamped on the measured surface, it is easy to move the vernier when taking it out for reading, resulting in the final reading being too large. Utility Model Content

DETAILED DESCRIPTION

[0026] The following embodiments of the technical solution of the present invention are described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.

[0027] See Figures 1 to 5 The utility model provides a wind turbine generator set measuring device, including a vernier ruler 100, a main ruler 200, an elastic reset member 300 and a locking member 400.

[0028] Specifically, the sidewall of the vernier ruler 100 is provided with a strip groove extending axially and communicating with its inner cavity. Vernier ruler 100 is provided with a vernier scale along the edge of the strip groove. One end of the main ruler 200 is slidably connected to the vernier ruler 100. Main ruler 200 is provided with a main size scale along its axial direction. The top end of main ruler 200 is located within vernier ruler 100, and the bottom end of main ruler 200 extends from the bottom end of vernier ruler 100. When main ruler 200 moves axially along vernier ruler 100, the main size scale sequentially passes through the strip groove. An elastic reset member 300 is connected between vernier ruler 100 and main ruler 200. When the axial driving force acting on main ruler 200 is released, the elastic reset member 300 can drive main ruler 200 to reset. The locking member 400 is connected to the main pipe ruler 200 and the vernier pipe ruler 100 to lock and fix the main pipe ruler 200 and the vernier pipe ruler 100 .

[0029] During measurement, the locking member 400 releases the lock between the vernier ruler 100 and the main ruler 200. The main ruler 200 is then pressed inwards into the vernier ruler 100, compressing the elastic return member 300 until it is fully inserted into the vernier ruler 100. The locking member 400 then locks the vernier ruler 100 and the main ruler 200 together.

[0030] Next, place the entire measuring device between the two measured surfaces, bringing the top of the vernier ruler 100 into contact with one of the measured surfaces. Then, release the locking member 400. Under the action of the elastic return member 300, the main ruler 200 automatically extends outward until it contacts the other measured surface. The locking member 400 then secures the vernier ruler 100 and main ruler 200. The measuring device can then be removed and a reading can be taken.

[0031] With this measuring device, since both ends of the measuring device come into surface contact with the two end surfaces of the object during measurement, the contact area is increased, thereby ensuring perpendicularity between the measuring device and the object, thereby improving measurement quality. Furthermore, between readings, the vernier ruler 100 and the main ruler 200 are locked together by a locking mechanism to prevent relative movement of the vernier ruler 100 and the main ruler 200 when the vernier ruler 100 and the main ruler 200 are removed for reading, which could result in an inaccurate final reading.

[0032] In this embodiment, the locking member 400 includes a first locking disc 410 and a second locking disc 430. The first locking disc 410 is slidably mounted on the vernier scale 100. The vernier scale 100 is provided with a first slot 110 extending axially thereof. A first latch 420 is provided on the inner wall of the first locking disc 410 and is slidably inserted into the first slot 110. The second locking disc 430 is mounted on the vernier scale 100. The side wall of the vernier scale 100 is provided with an annular groove 120 communicating with the inner cavity thereof. The side wall of the main tube scale 200 is provided with a spiral groove 210 coaxial with the main tube scale 200, with the annular groove 120 intersecting the spiral groove 210. The second locking disc 430 is provided with a second latch 440, which is slidably inserted through the annular groove 120 into the spiral groove 210. The first locking disk 410 and the second locking disk 430 are locked by magnetic attraction.

[0033] In the non-operating state, the first locking disc 410 and the second locking disc 430 are magnetically attracted to each other, preventing the second locking disc 430 from rotating, thereby preventing the main pipe ruler 200 from sliding. During measurement, the first locking disc 410 and the second locking disc 430 are separated. Pressing the main pipe ruler 200 compresses the elastic return element 300, causing the second locking disc 430 to rotate. Once the main pipe ruler 200 is fully inserted into the vernier pipe ruler 100, the first locking disc 410 is slid so that it attracts the second locking disc 430, locking the main pipe ruler 200 in place. The entire measuring device is then placed between two measured surfaces, with the top end of the vernier ruler 100 in contact with one of the measured surfaces. The first locking disk 410 is slid toward the rear end of the vernier ruler 100, separating the first locking disk 410 from the second locking disk 430. The elastic return member 300 is deployed. When the bottom end of the main ruler 200 contacts the other measured surface, the first locking disk 410 is released, securing the main ruler 200.

[0034] In this embodiment, the main pipe ruler 200 is a hollow tube with a closed bottom end and an open top end. The top end of the main pipe ruler 200 is inserted into the vernier pipe ruler 100, and the two ends of the elastic return member 300 respectively abut against the inner bottom end of the main pipe ruler 200 and the inner top end of the vernier pipe ruler 100.

[0035] In this embodiment, the main pipe ruler 200 is a hollow tube with a closed bottom end and an open top end. The top end of the main pipe ruler 200 is inserted into the vernier pipe ruler 100, and the two ends of the elastic return member 300 respectively abut against the inner bottom end of the main pipe ruler 200 and the inner top end of the vernier pipe ruler 100.

[0036] When the measuring device is taken out, the movable push rod 500 can be pressed into the main pipe ruler 200 , which facilitates the removal without affecting the measurement data.

[0037] As another preferred embodiment, the device further includes a zero adjustment assembly 600, which is disposed at the top of the vernier ruler 100 and abuts against the top end of the elastic return member 300. When the spring force weakens, the zero adjustment assembly 600 can be adjusted to achieve the zero adjustment effect.

[0038] Specifically, the zero adjustment assembly 600 includes an adjusting screw, and the inner wall of the top end of the vernier ruler 100 is provided with an internal thread. The adjusting screw is threadedly connected to the vernier ruler 100 through the internal thread. The end of the adjusting screw extends into the vernier ruler 100 and abuts against the top end of the elastic reset member 300.

[0039] During use, when the spring force weakens, the elastic reset member 300 can be compressed by screwing in the adjusting screw, thereby achieving the effect of zero adjustment.

[0040] The usage of the above-mentioned wind turbine generator measurement device is as follows:

[0041] In the non-operating state, the elastic return member 300 is deployed, pushing the movable ejector rod 500 and the main ruler 200 out. The zero mark of the vernier ruler 100 points to the minimum mark of the main ruler 200 (e.g., the 150mm mark). The first locking plate 410 attracts the second locking plate 430, preventing the main ruler 200 from sliding. During measurement, the first locking plate 410 is slid apart from the second locking plate 430. Pressing the main ruler 200 compresses the elastic return member 300, causing the second locking plate 430 to rotate. When the main ruler 200 is fully pressed into the vernier ruler 100, the first locking plate 410 is released to secure the main ruler 200.

[0042] The entire measuring device is then placed between the two measured surfaces, with the top surface of the vernier ruler 100 in contact with one of the measured surfaces. The first locking disc 410 is slid apart from the second locking disc 430, and the elastic reset member 300 is deployed. Once the end surface of the movable push rod 500 contacts the other measured surface, the first locking disc 410 is released to secure the main ruler 200. The movable push rod 500 is then pressed to remove the cylindrical vernier caliper and take a reading. During removal, the movable push rod 500 can be pressed into the main ruler 200, making it easy to remove without affecting the measured data. When the spring force weakens, the elastic reset member 300 can be compressed by screwing in the adjusting screw to achieve zero adjustment.

[0043] With the wind turbine generator set measuring device described above, since both ends of the measuring device make surface contact with the two side surfaces of the measured surface during measurement, the contact area can be increased, thereby ensuring the perpendicularity between the measuring device and the measured surface, thereby improving the measurement quality. In addition, between readings, the vernier ruler 100 and the main ruler 200 are locked by the locking member 400 to prevent the vernier ruler 100 and the main ruler 200 from moving relative to each other when the vernier ruler 100 and the main ruler 200 are removed for reading, which could cause the final reading to be offset.

[0044] Furthermore, the movable ejector 500 ensures the device's stability during measurement. Furthermore, when removing the measuring device, the movable ejector 500 can be pressed into the main pipe 200, allowing for easy removal without affecting measurement data. If the spring force weakens, the zero adjustment assembly 600 can be used to adjust the spring force to zero.

[0045] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention, and they should all be included in the scope of the claims and description of the present invention.
