DETAILED DESCRIPTION

[0024] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0025] In this disclosure, unless otherwise stated, directional words such as "upper, lower, left, right, front, and rear" are used to facilitate description and are defined according to the drawing direction of the corresponding drawings, and "inside and outside" are defined according to the contours of the corresponding parts. Terms such as "first, second" and the like used in this disclosure are used to distinguish one element from another and do not have order or importance. In addition, when the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0026] The generator may include a housing, a rotor assembly and a stator assembly disposed in the housing, the stator assembly being disposed at the periphery of the rotor assembly, the rotor assembly including a rotor and a magnet mounted on the rotor, and the stator assembly may include a wire winding and an iron core. The probe of the detection element is close to the periphery of the rotating shaft to detect various performance parameters of the generator. However, due to different models and sizes of the generator, the position of the rotating shaft changes. In the related art, the position of the probe of the detection element is fixed and cannot be adjusted according to different rotating shafts, resulting in relatively inaccurate data measured.

[0027] To solve the above problems, see Figure 1 and Figure 2 The embodiment of the present disclosure provides a generator detection device, which may include a frame 1, a drive mechanism and a detection element. The frame 1 may be provided with a fixed station for placing the generator 103. The drive mechanism may be installed on the frame 1. The detection element may be installed on the frame 1 through the drive mechanism, wherein the position of the detection element is adjustable above the fixed station.

[0028] It is understandable that the generator 103 is fixed to a fixed position of the frame 1, and the detection element is installed on the frame 1 through a driving mechanism, without the need for the user to manually hold the detection element. At the same time, the driving mechanism can drive the detection element to move according to the position of the rotating shaft to adjust the position of the probe of the detection element so that the probe can be close to the rotating shaft, ensuring that the data measured by the detection element is more accurate and reliable. For example, when the size of the generator 103 is large, its rotating shaft is higher from the ground, and the driving mechanism can raise the height of the detection element from the ground so that its probe can be close to the outer periphery of the rotating shaft, ensuring that the data measured by the detection element is more accurate and reliable.

[0029] In one embodiment, see Figure 1 , Figure 2 and Figure 4 , the detection element is a Hall sensor 102 for detecting the magnetic properties of the generator. The probe of the Hall sensor 102 can act on the outer peripheral wall of the rotating shaft of the generator 103 and close to the end face of the rotor. It should be noted that the detection position of the generator 103 of the same model and size is unchanged. The detection element may include the Hall sensor 102. Because the wire winding is located on the periphery of the rotor assembly, if the probe of the Hall sensor 102 is set on the upper part of the shell, the probe of the Hall sensor 102 is easily interfered by the wire winding when detecting the magnetic steel, resulting in inaccurate measured data. The rotating shaft of the generator 103 drives the rotor and the magnetic steel to rotate, and the magnetic field of the magnetic steel will change. The Hall sensor 102 can indirectly sense the magnetic properties of the magnetic steel by sensing the changing magnetic field of the rotating shaft. Of course, the detection element can also include a speed sensor and a vibration detection sensor.

[0030] In one embodiment, see Figure 1 , Figure 2 and Figure 4 The driving mechanism may include a first driving component and a second driving component, the second driving component is connected to the first driving component and the Hall sensor 102 respectively, the first driving component drives the second driving component and the Hall sensor 102 to move in the horizontal direction, and the second driving component drives the Hall sensor 102 to move up and down in the vertical direction, so that the probe is close to the detection position. By setting the first driving component and the second driving component, the Hall sensor 102 can move in a two-dimensional space, so that it is convenient for it to approach the detection position, so as to meet the detection of generators 103 of different models and sizes.

[0031] In one embodiment, see Figure 1 , Figure 2 and Figure 4 , the frame 1 is provided with a slide groove 2 extending in the horizontal direction. The first driving assembly may include a slider 201, a connecting pipe 202 and a first screw rod 203. The slider 201 may be slidably matched with the slide groove 2, the frame 1 is provided with a slot connected to the slide groove 2, and the connecting pipe 202 is arranged in the slot and cannot rotate. The first screw rod 203 may be screwed to the frame 1 directly or through a bearing, and may be screwed to the end of the connecting pipe 202 away from the slider 201. By rotating the first screw rod 203, the connecting pipe 202 may drive the slider 201 to move horizontally, so as to drive the Hall sensor 102 to move in the horizontal direction.

[0032] It is understandable that the arrangement of the connecting tube 202 can prevent the first screw rod 203 from directly wearing the slider 201. Figure 1 , Figure 2 and Figure 4 If the detection position of the generator 103 to be detected moves to the left compared to the detection position of the previous generator 103, the worker can rotate the first screw rod 203. Because the slide slot 2 can limit the rotation of the connecting tube 202, the connecting tube 202 can only move linearly to the left under the drive of the first screw rod 203, so that the second drive assembly can drive the Hall sensor 102 to move to the left to approach the detection position. Similarly, the worker can rotate the first screw rod 203 in the opposite direction to move the Hall sensor 102 to the right.

[0033] In another embodiment, the first driving component may be a linear module, a cylinder or a crank slider 201 mechanism, etc., to meet the horizontal movement of the Hall sensor 102.

[0034] In one embodiment, see Figure 2 , Figure 3 , Figure 5 and Figure 6, the second driving assembly may include a first rack 205 and a limit module. The first rack 205 may be slidably connected to the slider 201 and may be connected to the Hall sensor 102. The limit module may be disposed between the slider 201 and the first rack 205, and the limit module may have a locked state and an unlocked state, wherein when the limit module is in the unlocked state, the first rack 205 may move in the up-down direction; when the limit module is in the locked state, the position of the first rack 205 in the up-down direction is fixed to prevent the Hall sensor 102 from sliding down during the magnetic property detection process.

[0035] It can be understood that, for example, after the detection position of the generator 103 to be detected moves upward compared to the detection position of the previous generator 103, the limit module can unlock the first rack 205, so that the first rack 205 can be lifted and slid relative to the slider 201, and the worker can pull the first rack 205 upward so that the Hall sensor 102 can move upward to the detection position, and then the limit module can limit the relative movement between the first rack 205 and the slider 201 to ensure that the probe of the Hall sensor 102 can continue to be in the detection position.

[0036] In another embodiment, the second driving assembly may be a worm gear mechanism to enable the Hall sensor 102 to perform lifting and lowering motions.

[0037] In one embodiment, see Figure 5 and Figure 6 The frame 1 is provided with a sliding hole 212 , and slide plates 211 are provided on both sides of the first rack 205 , and the slide plates 211 are slidably connected with the sliding hole 212 .

[0038] In one embodiment, see Figure 2 and Figure 3 , the slider 201 may be provided with a mounting cavity 207. The limiting module may include a first gear 204, a second rack 206 and a screw 208. The first gear 204 may be rotatably connected to the cavity wall of the mounting cavity 207 directly or through a bearing, and may be meshed with the first rack 205. The second rack 206 may be provided in the mounting cavity 207, and may contact two opposite cavity walls of the mounting cavity 207. The screw 208 may extend into the slider 201, and may be threadedly connected with the second rack 206 and the slider 201. The screw 208 is rotated to make the second rack 206 approach or move away from the first gear 204. When the second rack 206 moves to mesh with the first gear 204, the limiting module is in a locked state; when the second rack 206 moves to disengage from the first gear 204, the limiting module is in an unlocked state.

[0039] For example, after the detection position of the generator 103 to be detected moves upward compared to the detection position of the previous generator 103, the screw 208 is rotated so that the second rack 206 can be disengaged from the first gear 204 downward, releasing the rotation limit on the first gear 204, and pulling the first rack 205 upward so that the first rack 205 can drive the Hall sensor 102 to move upward to approach the detection position. At this time, the first gear 204 can rotate, and the screw 208 is rotated in the opposite direction so that the second rack 206 can move upward until it is meshed with the first gear 204, thereby making the first gear 204 unable to rotate, thereby limiting the movement of the second rack 206 meshed with the first gear 204, ensuring that the probe of the Hall sensor 102 can work stably, thereby ensuring that the data measured by the probe can be relatively accurate.

[0040] In another embodiment, the limiting module may include a plurality of ratchets, which may be rotatably connected to the slider 201. The ratchets may be rotated so as to engage with the first rack 205 to limit the lifting and lowering movement of the first rack 205. The ratchets may be rotated in the opposite direction to release the lock on the position of the first rack 205.

[0041] In one embodiment, see Figure 1 and Figure 2 The detection device may also include a display 101 installed on the frame 1. The connection port of the display 101 may be connected to the Hall sensor 102 via a cable. The Hall sensor 102 transmits the measured data to the display 101 via the cable, so that the worker can understand the magnetic properties of the magnet by observing the display 101.

[0042] In one embodiment, see Figure 2 , Figure 3 , Figure 5 and Figure 6 , at least one elastic buckle 209 for fixing the cable is provided on the first rack 205 to ensure the stability of the Hall sensor 102. The elastic buckle 209 is made of deformable plastic. When the detection device is in the initial state, one of the multiple elastic buckles 209 can be at the same height as the wiring port, and the elastic buckle 209 can be engaged with the end of the cable close to the Hall sensor 102. A connecting pad 210 is provided on the inner periphery of the elastic buckle 209. The connecting pad 210 can be made of rubber material, which has a certain deformation ability to prevent the elastic buckle 209 from directly contacting the cable and avoiding wear of the cable.

[0043] It can be understood that the initial state is the state of the detection device when it leaves the factory. The end of the cable close to the Hall sensor 102 is at the same height as the wiring port, so that the cable between the wiring port of the display 101 and the Hall sensor 102 is shorter, avoiding the cable being stretched and damaged due to being too long.

[0044] In one implementation, the orthographic projection of the Hall sensor 102 in the up-down direction may be located on the axis of the slide slot 2 .

[0045] There are many ways to keep the generator 103 at a fixed position. In the present disclosure, the generator detection device further includes a limit mechanism provided at the fixed position, and the limit mechanism is used to keep the generator 103 at the fixed position to prevent the generator 103 from moving during the movement.

[0046] In one embodiment, see Figure 1 and Figure 7 The limiting mechanism may include four guide grooves 3 and four limiting members 301. The four guide grooves 3 may be arranged at an angle to the horizontal direction, and every two guide grooves 3 may be symmetrically arranged on the workstation. The four limiting members 301 are arranged in a one-to-one correspondence with the four guide grooves 3. Among the four limiting members 301, at least some of the limiting members 301 are adjustable in position in the corresponding guide grooves 3, which is suitable for limiting and fixing generators 103 of different sizes and types.

[0047] It can be understood that when the generator 103 is placed on a fixed workstation, the adjustable limit member 301 can slide in the guide groove 3 to push the generator 103 to move on the fixed workstation, so that the rotating shaft of the generator 103 can be located directly below the Hall sensor 102, ensuring that more magnetic flux lines can pass through the probe of the Hall sensor 102.

[0048] In this embodiment, the four stoppers 301 can all move in the slide groove 2. By setting four sets of guide grooves 3 and stoppers 301, the generator 103 can be pushed to move in the front-back and left-right directions, so as to facilitate the adjustment of the position of the generator 103 on the fixed station and ensure that its rotating shaft can be located directly below the probe of the Hall sensor 102. At the same time, the worker can adjust the movement of the first drive assembly and the second drive assembly so that the Hall sensor 102 can move in the horizontal direction and rise and fall in the vertical direction, so that the probe can be close to the detection position.

[0049] In one embodiment, see Figure 1 and Figure 7, the extension lines of the four guide grooves 3 have an intersection, and the intersection and the projection in the up and down directions are located on the axis of the slide groove 2. The four limit members 301 are respectively provided with a set of transmission components, and the transmission components may include a toothed disc 306, a first bevel gear 304, a second bevel gear 305 and a second screw rod 303 respectively located in the frame 1, the second bevel gear 305 may be coaxially connected to the toothed disc 306, and may be meshed with the first bevel gear 304, the second screw rod 303 may be coaxially connected to the first bevel gear 304, the limit member 301 may be sleeved on the outer periphery of the second screw rod 303, and may be screwed with the second screw rod 303, and the limit member 301 may contact the side wall of the guide groove 3. The limiting mechanism may also include a toothed belt 307, and the toothed belt 307 may be wound around the four toothed discs 306 of the four sets of transmission components, and the rotation directions of the two symmetrical second screw rods 303 are opposite. Combination Figure 7 For example, in order to facilitate the description of the four second screw rods 303, they are named second screw rod A303, second screw rod B303, second screw rod 303 and second screw rod D303 respectively. The rotation directions of the second screw rod A303 and the second screw rod C303 are opposite, the rotation directions of the second screw rod B303 and the second screw rod D303 are opposite, the rotation directions of the second screw rod B303 and the second screw rod C303 are the same, and the rotation directions of the second screw rod A303 and the second screw rod D303 are the same. Therefore, when the toothed belt 307 rotates clockwise, the second screw rod A303 and the second screw rod C303 on the diagonal line can approach each other, and the second screw rod B303 and the second screw rod D303 on the diagonal line can approach each other. When the four limit members 301 are in contact with the generator 103, the center of the generator 103 is located above the intersection of the extension lines of the four guide grooves 3. Because the rotating shaft of the generator 103 can pass through the center line of the generator 103, the rotating shaft can be located directly below the positive projection of the Hall sensor 102, ensuring that more magnetic flux lines on the rotating shaft can pass through the probe of the Hall sensor 102, thereby ensuring the detection effect of the probe. Similarly, rotating the toothed belt 307 counterclockwise allows the two second screw rods 303 on the diagonal line to move away from each other to release the restriction on the position of the generator 103. Setting a toothed belt 307 can realize the synchronous movement of the four limit members 301, saving the driving member used to drive the limit member 301 to move.

[0050] In one embodiment, see Figure 7 A connecting plate 302 is installed on the upper part of the limit member 301. The four limit members 301 can respectively drive the four connecting plates 302 to approach each other, so that the rotating shaft of the direct-drive permanent magnet generator 103 can be located directly below the Hall sensor 102, ensuring that more magnetic flux lines on the rotating shaft can pass through the probe of the Hall sensor 102.

[0051] In one embodiment, see Figure 7The limiting mechanism may also include a driving motor 310, a second gear 309 and a plurality of tensioning wheels 308. The rotating shaft of the driving motor 310 may be connected to the second gear 309 in a transmission manner. The second gear 309 may mesh with the toothed belt 307. The plurality of tensioning wheels 308 may be respectively close to the plurality of toothed discs 306 and may contact the outer side of the toothed belt 307. The tensioning wheels 308 may adjust the tightness of the toothed belt 307 to ensure that the toothed belt 307 maintains appropriate tension during operation, thereby preventing the toothed belt 307 from aging prematurely due to slippage or excessive wear. The driving motor 310 may drive the second gear 309 to rotate, so that the toothed disc 306 drives the first bevel gear 304 to rotate.

[0052] It is understandable that the drive motor 310 can drive the second gear 309 to rotate, so that the toothed belt 307 can simultaneously drive the four toothed discs 306 to rotate, so that the four limit members 301 can be close to each other, so that the limit members 301 can limit the direct-drive permanent magnet generators 103 of different sizes, so that the shaft of the direct-drive permanent magnet generator 103 can be quickly adjusted to the bottom of the Hall sensor 102. When the direct-drive permanent magnet generator 103 is detected, the drive motor 310 can drive the second gear 309 to rotate in the opposite direction, and the limit member 301 can release the restriction on the position of the direct-drive permanent magnet generator 103.

[0053] When the Hall sensor 102 detects the direct-drive permanent magnet generator 103, firstly, the cable is connected to the elastic buckle 209, and then the direct-drive permanent magnet generator 103 is placed on the work station, and the drive motor 310 is started, so that the four limit members 301 can move forward and backward, left and right, so as to push the rotating shaft of the direct-drive permanent magnet generator 103 to be located directly below the Hall sensor 102. The first screw rod 203 is rotated so that the slider 201 can drive the second drive assembly and the Hall sensor 102 to approach the detection position in the horizontal direction. The first rack 205 drives the Hall sensor 102 to move downward or upward, so that the probe of the Hall sensor 102 can approach the detection position in the height direction. Through the above operation, the probe of the Hall sensor 102 can approach the detection position in three dimensions.

[0054] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.
