[0019] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0025] In the description of the embodiments of the present application, "vertical" is not strictly perpendicular, and a certain error is allowed. "Parallel" is not strictly parallel, and a certain error is allowed.

[0026] Due to factors such as high speed and variable working conditions, the outer cylindrical structure of the motor rotor (such as the rotor of a hydro-turbine generator) is prone to abnormalities or faults such as open turns at the pole ends, loosening of the pole lead wires and rotor lead wires, abnormal deformation of the inter-pole connection wires and pole lead wires, and lead wire insulation burnout. Therefore, it is necessary to collect images of the motor.

[0027] The rotor image acquisition requires components such as cameras and light sources. The camera is used to acquire images of the rotor magnetic pole ends, and the light source is used to increase the ambient brightness. When assembling the motor, the camera and light source are installed separately, which affects the assembly efficiency of the motor.

[0028] Especially in a hydro-turbine generator, these components are usually separately arranged and need to be installed one by one. Due to the environmental restrictions of the hydro-turbine generator, the mechanism for monitoring the rotor is installed and debugged one by one, resulting in low assembly efficiency.

[0029] In view of this, an embodiment of the present application provides a rotor image acquisition device 100 , and the specific structure of the rotor image acquisition device 100 is described in detail below in conjunction with the accompanying drawings.

[0030] The technical solution provided in the embodiment of the present application is particularly suitable for large-volume generators, motors and other electric machines. Large-volume electric machines provide an installation basis for the rotor image acquisition device 100 to be assembled in the electric machine. For the convenience of description, the following description is taken as an example of a hydro-turbine generator.

[0031] Reference Figures 1 to 4 The rotor image acquisition device 100 includes a housing 10 , a camera 20 and a light source 30 .

[0032] The housing 10 has a light-transmitting portion for light to enter and exit. The light-transmitting portion may be an opening formed on the housing 10 , or may be a transparent area formed by a portion of the housing 10 made of a transparent material.

[0033] The camera 20 and the light source 30 are both contained in the housing 10, and the lens 21 of the camera 20 faces the light-transmitting portion, so that the camera 20 can capture the rotor image through the light-transmitting portion. In specific applications, the camera 20 can be used to capture the image of the rotor magnetic pole tip. In specific applications, the rotor image acquisition device 100 is installed on the motor, and the lens 21 of the camera 20 can face the rotor magnetic pole tip.

[0034] The light source 30 is spaced apart from the camera 20, and the light emitting direction of the light source 30 is toward the light-transmitting portion. The light source 30 is configured to illuminate the framing range of the camera 20 so that the camera 20 can form an image. The light source 30 can be selected according to the brightness requirement. The light source 30 can include but is not limited to a high-brightness LED cold light source 30, a small lamp bead LED, etc.

[0035] In this embodiment, the camera 20 and the light source 30 are both arranged in the housing 10, that is, the rotor image acquisition device 100 integrates the camera 20 and the light source 30 together, so that the rotor image acquisition device 100 can be used as a prefabricated part and directly assembled on the motor, that is, the camera 20 and the light source 30 can be installed on the hydro-turbine generator at one time, and there is no need to install the camera 20 and the light source 30 on the hydro-turbine generator. The assembly of the prefabricated parts and the installation of the prefabricated parts on the motor can be carried out simultaneously, which can improve the assembly efficiency.

[0036] Specifically, the rotor image acquisition device 100 is a prefabricated part. In the actual production process, the production line of the rotor image acquisition device 100 and the assembly line of the motor can be carried out in parallel, so that more rotor image acquisition devices 100 can be prepared and more motors can be assembled in the same time, thereby improving efficiency.

[0037] In some embodiments, the housing 10 is provided with a flange 14, which facilitates the installation of the rotor image acquisition device 100 in the motor. Figure 1 and Figure 2 As shown, a flange portion 14 is disposed on the top of the housing 10 , and the flange portion 14 is located at an end of the housing 10 away from the light-transmitting portion to reduce shielding of the light-transmitting portion.

[0038] Reference Figure 1 , Figure 2 and Figure 4 In some embodiments, the light-transmitting portion is a light-transmitting plate 12. Specifically, the housing 10 includes a housing 11, a light-transmitting plate 12 and a cover plate 13. The bottom of the housing 11 forms a first opening 111, and the top of the housing 11 forms a second opening 112. The first opening 111 is connected to the interior of the housing 10, and the second opening 112 is connected to the interior of the housing 10. The first opening 111 and the second opening 112 facilitate the placement of the light source 30 and the camera 20 into the housing 10, thereby reducing the difficulty of assembling the rotor image acquisition device.

[0039] The light-transmitting plate 12 covers the first opening 111. The cover plate 13 covers the second opening 112. The lens 21 of the camera 20 faces the light-transmitting plate 12. The cover plate 13 covers the second opening 112. The light-transmitting plate 12, the cover plate 13 and the housing 11 define an internal environment for accommodating the camera 20 and the light source 30, which can greatly reduce the pollution of foreign matter such as oil or dust in the motor to the camera 20 and the light source 30 during the use of the rotor image acquisition device 100, thereby extending the service life of the camera 20 and the light source 30.

[0040] In some embodiments, the base material of the light-transmitting plate 12 includes, but is not limited to, colorless polycarbonate, acrylic, etc. The light-transmitting plate 12 made of these materials has good mechanical strength and light transmittance.

[0041] In some embodiments, in order to improve the sealing effect, the light-transmitting plate 12 and the housing 11 can be sealed by a seal. Specifically, the seal is at least partially disposed between the light-transmitting plate 12 and the housing 11 and is disposed around the light-transmitting plate 12 to seal the risk between the light-transmitting plate 12 and the housing 11.

[0042] Since the operation of the motor is a high-frequency vibration, which makes the light-transmitting plate 12 easy to break, it is possible to consider setting the seal as a flexible seal 60 to play a sealing and buffering role. Specifically, a ring-shaped groove can be set on the end surface of the housing 11 facing the light-transmitting plate 12, and the flexible seal 60 is provided with a protrusion matching the ring-shaped groove, and the flexible seal 60 is fixed to the housing 11 by the protrusion being snapped into the groove. The flexible seal 60 is arranged around the light-transmitting plate 12, and the flexible seal 60 transitionally matches the outer peripheral surface of the light-transmitting plate 12, and the light-transmitting plate 12 is fixed to the housing 11 through the flexible seal 60.

[0043] The flexible seal 60 can be made of a high temperature resistant or oil resistant material to ensure that the flexible seal 60 remains stable in a high temperature environment and is not easily decomposed or aged by reacting with the oil in the motor.

[0044] Optionally, the material of the flexible sealing member 60 includes foamed silicone and / or foamed fluororubber.

[0045] Furthermore, the light-transmitting plate 12 and the shell 11 can be connected by fasteners to improve the connection stability between the light-transmitting plate 12 and the shell 11. The position of the fasteners can avoid the vicinity of the outer peripheral surface of the light-transmitting plate 12 to reduce the risk of interference between the fasteners and the flexible seal 60, resulting in the flexible seal 60 and the light-transmitting plate 12 not being able to fit tightly.

[0046] In some embodiments, the end surface of the flexible seal 60 facing away from the camera 20 extends beyond the light-transmitting plate 12 to largely prevent foreign objects from approaching the light-transmitting plate 12 and affecting light transmission.

[0047] Reference Figure 5 and Figure 2 In some embodiments, two light sources 30 are provided, and the two light sources 30 are respectively provided on both sides of the camera 20 .

[0048] Specifically, the housing 11 is provided with two mounting grooves 113, and the two light sources 30 are respectively arranged in the two mounting grooves 113. In order to facilitate the assembly of the light source 30, the notch of the mounting groove 113 can be larger than the light source 30, and the light source 30 is restricted from escaping from the mounting groove 113 by the mounting plate 90. The mounting plate 90 and the housing 11 can be connected by fasteners. The fasteners include but are not limited to bolts, screws, buckles, etc.

[0049] Reference Figure 6 and Figure 7 In some embodiments, the rotor image acquisition device 100 further includes a first adjustment mechanism 40, which is disposed on the housing 10. The first adjustment mechanism 40 can be used to move the camera 20 along an extension direction P of an optical axis of the camera 20 to adjust the distance between the camera 20 and the rotor.

[0050] By setting the first adjustment mechanism 40 to move the camera 20 , the camera 20 can be moved closer to or farther away from the rotor, so that the camera 20 can be adjusted to a suitable position corresponding to the part of the rotor that needs to be captured, thereby improving the compatibility of the rotor image acquisition device 100 .

[0051] Reference Figures 6 to 8 In some embodiments, the first adjustment mechanism 40 may include a first fixing frame 41 , a second fixing frame 43 and an adjustment rod 42 .

[0052] The first fixing frame 41 includes a fixing plate 411 and two fixing blocks 412 fixed to the fixing plate 411. The fixing plate 411 can be constructed in an L shape. The end edge of the L-shaped fixing plate 411 is connected to the housing 11, so that the first fixing frame 41 is fixed to the housing 10. The two fixing blocks 412 are arranged at intervals along the extension direction P of the optical axis. A guide rod 414 can be connected between the two fixing blocks 412, and the adjustment rod 42 is rotatably installed on the two fixing blocks 412.

[0053] Among them, Figure 8 As shown, the second fixing frame 43 may include a first connecting plate 431 and a slider 413 . The thickness direction of the first connecting plate 431 is parallel to the thickness direction of the fixing plate 411 . The slider 413 is fixed to a side of the first connecting plate 431 facing the fixing plate 411 .

[0054] The two guide rods 414 are passed through the slider 413 , and the slider 413 is located between the two fixing blocks 412 . The adjusting rod 42 has an external thread. The slider 413 is sleeved on the adjusting rod 42 and is threadedly driven with the adjusting rod 42 to realize the transmission connection between the second fixing frame 43 and the adjusting rod 42 .

[0055] The camera 20 is fixed to the side of the first connecting plate 431 away from the fixed plate 411. The rotation of the adjusting rod 42 can drive the slider 413 to move along the extension direction P of the optical axis of the camera 20. The first connecting plate 431 moves along the extension direction P of the optical axis of the camera 20 driven by the slider 413, thereby driving the camera 20 to move, thereby realizing the adjustment of the position of the camera 20.

[0056] It should be noted that, in other embodiments, the first adjustment mechanism 40 may not adopt the above structure. For example, the first adjustment mechanism 40 may include a first fixing frame 41, an adjustment rod 42, and a second fixing frame 43. The first fixing frame 41 is connected to the housing 10, the adjustment rod 42 is movably disposed on the first fixing frame 41 along the extension direction P of the optical axis of the camera 20, the adjustment rod 42 is rotatably connected to the second fixing frame 43, and the camera 20 is installed on the second fixing frame 43 (not shown in the figure of this embodiment). The movement of the adjustment rod 42 drives the movement of the second fixing frame 43, and the camera 20 moves under the drive of the second fixing frame 43, thereby realizing the adjustment of the distance between the camera 20 and the rotor.

[0057] Reference Figure 4 In some embodiments, the inner circumference of the housing 11 is provided with a boss 114, and the fixing plate 411 is mounted on the boss 114. The boss 114 can provide a good installation foundation and support for the fixing plate 411, and improve the connection stability between the fixing plate 411 and the housing 11.

[0058] In some embodiments, the rotor image acquisition device 100 further includes a first locking mechanism, which is mounted on the housing 10, and specifically can be mounted on the cover plate 13 of the housing 10. One end of the adjustment rod 42 extends out of the cover plate 13, and the first locking mechanism is used to lock the end of the adjustment rod 42 located outside the housing 10 with the cover plate 13.

[0059] Specifically, the first locking mechanism includes a first fixed disk 200 and a positioning pin (not shown in the figure), the first fixed disk 200 is fixed to the cover plate 13, the first fixed disk 200 is sleeved on the adjusting rod 42, a through hole is provided on the peripheral side of the first fixed disk 200, the positioning pin is movably provided in the through hole, and the positioning pin is used to abut against the adjusting rod 42 along the radial direction of the adjusting rod 42, thereby realizing the locking of the adjusting rod 42 and the outer shell 10.

[0060] The first locking mechanism locks the end of the adjustment rod 42 outside the housing 10 with the housing 10, which helps to reduce the risk of the adjustment rod 42 loosening and causing the camera 20 to be unstable after the distance between the camera 20 and the rotor is adjusted to the right position.

[0061] In some embodiments, reference Figure 6 The rotor image acquisition device 100 further includes a second adjustment mechanism on the housing of the second adjustment mechanism. The second adjustment mechanism is used to drive the adjustment ring of the camera 20 to rotate to adjust the focal length of the camera 20.

[0062] Specifically, the second adjustment mechanism may be a focus rod 50 , and the focus rod 50 is transmission-connected to the focus ring 22 to drive the focus ring 22 to rotate.

[0063] For example, in Figure 6In the embodiment, one end of the focus rod is provided with a convex tooth, and the outer surface of the focus ring 22 is provided with a convex tooth that cooperates with the focus rod 50. It should be noted that in this embodiment, the focus rod 50 can drive the focus ring 22 to rotate, and the focus ring 22 can have a certain displacement relative to the focus rod 50 during the rotation process.

[0064] In other embodiments, the focus rod 50 and the focus ring 22 may also be threaded.

[0065] In some embodiments, reference Figure 6 and Figure 8 , the focus lever can share the second fixing frame 43 with the camera 20. Specifically, the second fixing plate 411 can also include a second connecting plate 432, the first connecting plate 431 is perpendicular to the second connecting plate 432, the second connecting plate 432 is connected to one end of the first connecting plate 431, and the second connecting plate 432 is located in front of the lens 21. The second connecting plate 432 is also provided with an avoidance hole 4321 corresponding to the position of the lens 21, and the avoidance hole 4321 is used to avoid the lens 21 to prevent the second connecting plate 432 from blocking the lens 21.

[0066] A mounting block 4322 is provided on the second connecting plate 432 , and the focus rod is rotatably mounted on the mounting block 4322 . The focus rod extends along an extension direction P of the optical axis of the camera 20 .

[0067] In some embodiments, the focus lever 50 and the adjustment lever 42 are respectively disposed on two sides of the camera.

[0068] In some embodiments, the rotor image acquisition device 100 may further include a second locking mechanism, and the second locking mechanism is used to lock the end of the focus lever located outside the housing 10 with the housing 10 .

[0069] The structure of the second locking mechanism may be the same as or different from the structure of the first locking mechanism.

[0070] Reference Figure 6 In some embodiments, the second locking mechanism may also include a second fixed plate 300 and a positioning pin. The second fixed plate 300 is fixed to the cover plate 13. The second fixed plate 300 is sleeved on the focusing rod 50. A through hole is provided on the peripheral side of the second fixed plate 300. The positioning pin is movably provided in the through hole. The positioning pin is used to abut the focusing rod 50 along the radial direction of the focusing rod 50, thereby realizing the locking of the focusing rod 50 and the outer shell 10.

[0071] In order to improve the sealing effect of the rotor image acquisition device 100, the rotor image acquisition device 100 can also include a first cap body 70 and a second cap body 80. The first cap body 70 is covered at the end of the adjustment rod 42 extending out of the outer shell 10, and the second cap body 80 is covered at the end of the focusing rod 50 extending out of the outer shell 10.

[0072] In the structure where the first locking structure includes the first fixing plate 200, the first cap body 70 can be threadedly connected to the first fixing plate 200 to improve the sealing effect and reduce the risk of foreign matter entering the housing 10 from the side of the adjustment rod 42. Similarly, in the structure where the first locking structure includes the second fixing plate 300, the second cap body 80 can be threadedly connected to the second fixing plate 300 to improve the sealing effect and reduce the risk of foreign matter entering the housing 10 from the side of the focus rod 50.
