Description

Technical Field

[0001] The invention relates to the field of claw pole structures of generators, and in particular to a claw pole blank structure of a claw pole type generator with permanent magnet mounting grooves. Background Art

[0002] Claw-pole generator is a common type of synchronous generator. The "claw pole" refers to the shape of the magnetic poles on the rotor, which are usually designed into a claw-like structure to improve the efficiency and performance of the motor.

[0003] A permanent magnet is a material or device that can generate a persistent magnetic field. It is usually made of materials with high magnetic permeability and high remanence properties, such as iron, nickel, cobalt, and rare earth elements (such as neodymium, praseodymium, terbium, etc.). Unlike traditional temporary magnets (such as electromagnets), permanent magnets can continuously generate a stable magnetic field without the need for external power or current.

[0004] The traditional claw pole blank structure of the generator installs the permanent magnet through a single mounting slot, which causes the permanent magnet to move or leave the slot due to external vibration or changes in operating conditions, affecting the stable operation of the generator.

[0005] In summary, the prior art lacks a stable limiting technology for permanent magnets for a certain claw pole blank structure of a generator. Summary of the invention

[0006] The purpose of the present invention is to solve the shortcomings existing in the background technology and to propose a claw pole blank structure of a claw pole generator with permanent magnet mounting grooves.

[0011] Preferably, a plurality of arc-shaped heat sinks are connected and fixed to the claw pole body, and a plurality of heat dissipation holes are opened on the claw pole body.

[0012] Preferably, a pull ring is connected and fixed at one end of the sealing column, two placement grooves are provided on the sealing column, two abutment strips are slidably fitted in the placement grooves, the abutment strips abut against the inner wall of the claw pole body, a spring B is connected and fixed between the abutment strip and the sealing column, and a rubber pad is connected and fixed to the outer side of the abutment strip.

[0013] Preferably, the transmission mechanism comprises a push rod group, one end of which is rotatably connected to the sleeve cover, the other end of which is rotatably connected to a hinge seat, the hinge seat is fixedly connected to the sealing groove plate, and one end of the push rod group is fixedly connected to a gear.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] When installing the permanent magnet, by setting a limit mechanism, the permanent magnet can be effectively prevented from moving or leaving the slot due to external vibration or changes in operating conditions, ensuring the stable operation of the generator, thereby improving the performance and safety of the generator;

[0018] Before installing the permanent magnet, a sealing plate is provided to cover the installation slot to prevent dust, oil, etc. from entering the installation slot, thereby ensuring that the claw pole blank structure or the permanent magnet itself will not be damaged after the permanent magnet is installed.

[0019] By opening heat dissipation holes on the claw pole body and installing arc-shaped heat sinks, the claw pole blank structure is optimized to improve the thermal management efficiency and ensure that the cooling medium (such as air) can effectively flow around the claw pole blank structure to take away the heat in time and prevent the generator from overheating.

[0030] like Figure 1-Figure 8 The claw pole blank structure of a claw pole generator with a permanent magnet mounting groove shown in the figure comprises a claw pole body 1, a plurality of mounting grooves 2 are opened on the claw pole body 1, a permanent magnet 3 is mounted in the mounting groove 2, a plurality of limit mechanisms 4 are slidably arranged in the mounting groove 2, a transmission ring 5 is slidably arranged on the claw pole body 1, a sealing column 6 is abutted in the claw pole body 1, a sleeve cover 7 is slidably arranged on the sealing column 6, a plurality of transmission mechanisms 8 are rotatably connected to the sleeve cover 7, and a plurality of sealing groove plates 9 are slidably arranged on the sleeve cover 7.

[0031] like Figure 5 As shown, the limiting mechanism 4 includes a limiting block 401, a spring A402 is connected and fixed between the bottom end of the limiting block 401 and the mounting slot 2, and a sliding rod 403 is connected and fixed to the bottom of the limiting block 401.

[0032] The other end of the sliding rod 403 is rotatably connected to a connecting rod group 404, the other end of the connecting rod group 404 is connected and fixed to a rotating shaft 405, and the other end of the rotating shaft 405 is connected and fixed to a transmission wheel 406. The transmission wheel 406 enables the connecting rod group 404 to drive the limit block 401 to be retracted.

[0033] like Figure 4 As shown, a lever 501 is connected and fixed to the outside of the transmission ring 5, and one end of the transmission ring 5 located in the claw pole body 1 is connected and fixed to a limit ring 502, and a plurality of arc-shaped racks 503 are connected and fixed to the limit ring 502, and the arc-shaped racks 503 are meshed with the transmission wheel 406 for transmission. The arc-shaped racks 503 can drive the retraction of the plurality of limit blocks 401, so as to facilitate the rapid disassembly of the permanent magnet 3.

[0034] like Figure 3 As shown, a plurality of arc-shaped heat sinks 101 are connected and fixed to the claw-pole body 1, and a plurality of heat dissipation holes 102 are opened on the claw-pole body 1. The arc-shaped heat sinks 101 and the heat dissipation holes 102 can improve the heat dissipation efficiency of the claw-pole body 1.

[0035] like Figure 7 As shown, a pull ring 601 is connected and fixed at one end of the hole-sealing column 6, two placement grooves 605 are provided on the hole-sealing column 6, two abutment strips 602 are slidably fitted in the placement grooves 605, the abutment strips 602 abut against the inner wall of the claw pole body 1, a spring B603 is connected and fixed between the abutment strip 602 and the hole-sealing column 6, and a rubber pad 606 is connected and fixed to the outside of the abutment strip 602. The hole-sealing column 6 can seal the hole in the claw pole body 1 to prevent dirt from entering the hole in the claw pole body 1 before installation and affecting the service life.

[0036] like Figure 8As shown, the transmission mechanism 8 includes a push rod group 801, one end of which is rotatably connected to the cover 7, and the other end of the push rod group 801 is rotatably connected to a hinge seat 805, and the hinge seat 805 is fixedly connected to the sealing plate 9, and one end of the push rod group 801 is fixedly connected to a gear 802.
