Description

Technical Field

[0001] This invention relates to the field of permanent magnet motor technology, specifically a permanent magnet motor with a heat dissipation warning function. Background Technology

[0002] A permanent magnet motor is a type of motor that uses permanent magnets (such as neodymium iron boron and samarium cobalt) to generate a magnetic field, thereby converting electrical energy into mechanical energy. Unlike traditional electrically excited motors (which require current to be passed through windings to generate a magnetic field), the magnetic field in a permanent magnet motor is provided by the permanent magnet itself, eliminating the need for additional excitation current. Therefore, it has significant advantages in terms of efficiency, size, and energy consumption.

[0003] Existing permanent magnet motors have a critical temperature. When the operating temperature approaches or exceeds this value, the magnetism of the permanent magnet will be permanently lost, leading to a decline in motor performance or even failure. This requires maintenance and replacement of the permanent magnet inside the motor, which is a complicated process and increases maintenance costs. To address this, we propose a permanent magnet motor with a heat dissipation warning function. Summary of the Invention

[0004] The purpose of this invention is to provide a permanent magnet motor with a heat dissipation warning function, in order to solve the problem mentioned in the background art that when the operating temperature of a permanent magnet motor approaches or exceeds a certain value, the magnetism of the permanent magnet will be permanently lost, leading to a decline in motor performance or even failure. This requires the permanent magnet inside the motor to be maintained and replaced, which is a cumbersome maintenance process and increases maintenance costs.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a permanent magnet motor with a heat dissipation warning function, comprising: a motor;

[0007] The outer side of the pusher piece is slidably connected to the inside of the mounting sleeve, and the rear end of the pusher piece contacts the front side of the package.

[0008] The outer side of the sliding rod is slidably connected to the inside of the mounting sleeve, and the outer side of the sliding rod is provided with sharp edges.

[0009] The outer side of the mounting rod is slidably connected to a push ring, and the top of the push ring is fixedly connected to a push spring.

[0010] The top end of the push spring is fixedly connected to the top end of the inner part of the mounting shell, and the bottom end of the push ring is in contact with the top end of the mounting base.

[0011] The pressing block is C-shaped, with the alarm button and the off button located on the left and right sides of the front side of the pressing block, respectively.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example 1

[0028] Please see Figures 1 to 9 The present invention provides a technical solution: a permanent magnet motor with heat dissipation warning function, comprising: a motor 1, which is the main body of the permanent magnet motor and the core component for realizing the conversion of electrical energy and mechanical energy. Its normal operation generates heat, which is also the main monitoring object of the heat dissipation warning function;

[0029] It also includes: a mounting shell 2 fixedly connected to the top of the motor 1, which provides installation space and support for components such as the alarm light 12, alarm horn 13, and mounting rod 14, while protecting the internal components and preventing external factors from interfering with their normal operation; a heat-absorbing ring 3 is set inside the motor 1, which can efficiently absorb the heat generated when the motor 1 is working and transfer the heat to the mounting sleeve 4 connected to it, providing a heat source for subsequent temperature monitoring; the mounting sleeve 4 is fixedly connected to the top of the heat-absorbing ring 3, which on the one hand is fixed to the top of the heat-absorbing ring 3, and supports components such as the wrapping bag 5 and sliding rod 7. The smooth inner wall can reduce the resistance when the pushing plate 8 and sliding rod 7 slide, ensuring smooth movement of the components; the mounting sleeve 4 is filled with mercury 6 inside, which can expand or contract with the volume change of mercury 6. When the temperature rises, the mercury 6 expands, which expands the envelope 5 and pushes the pusher plate 8; when the temperature drops, the mercury 6 contracts, which contracts the envelope 5, providing space for the sliding rod 7 to reset. The envelope 5 contains mercury 6, which uses its physical property of thermal expansion and contraction as a temperature sensing medium. When the temperature of the motor 1 rises, the heat-absorbing ring 3 transfers heat to the mounting sleeve 4, and the mercury 6 expands due to heat, pushing the envelope 5 and the pusher plate 8, which in turn drives the sliding rod 7 to move. The sliding rod 7 is slidably connected inside the mounting sleeve 4. The sliding rod 7 slides inside the mounting sleeve 4 and is the intermediate component connecting the pusher plate 8 and the pressing block 9. It can transfer the thrust on the envelope 5 and the pusher plate 8 to the pressing block 9, realizing the transmission of force. The rear end of the sliding rod 7 is fixedly connected to the pusher plate 8. The rear end of the pusher plate 8 contacts the envelope 5, and the outer side slides inside the mounting sleeve 4, transferring the thrust generated by the expansion of the envelope 5 due to the mercury 6 to the sliding rod 7, playing a role in force transmission and guidance.

[0030] A pressing block 9 is fixedly connected to the front side of the sliding rod 7. When the sliding rod 7 slides forward, the pressing block 9 moves accordingly, pressing the alarm button 11 and the off button 20. At this time, the alarm light 12 will light up, and the alarm horn 13 will sound an alarm. A push spring 10 is sleeved on the outside of the sliding rod 7. When the temperature decreases, the mercury 6 contracts, the pushing force of the encapsulation bladder 5 on the push plate 8 decreases, and the elastic force of the push spring 10 drives the sliding rod 7 to return to its original position. An alarm button 11 is fixedly connected to the top of the motor 1. When the pressing block 9 moves forward due to the increase in temperature and presses the alarm button 11, the alarm light 12 and the alarm horn 13 can be triggered to work, emitting a warning signal. An alarm light 12 is fixedly connected to the front side of the mounting shell 2. An alarm horn 13 is fixedly connected to the front side of the mounting housing 2. A mounting rod 14 is slidably connected to the top of the mounting housing 2. The top of the mounting rod 14 is connected to a positioning piece 16, and the bottom is connected to a mounting base 15. The mounting base 15 and the shut-off button 20 can be moved by sliding up and down. The bottom of the mounting rod 14 is fixedly connected to the mounting base 15, which carries the shut-off button 20 and moves with the movement of the mounting rod 14. The rear end of the mounting base 15 is fixedly connected to the shut-off button 20. When the shut-off button 20 is pressed by the pressing block 9, the motor 1 will be shut off. The top of the mounting rod 14 is fixedly connected to a positioning piece 16. The positioning piece 16 is designed to cooperate with the positioning groove 17 to lock the mounting rod 14. The top of the mounting housing 2 has a positioning groove 17, and the positioning piece 16 engages with the positioning groove 17.

[0031] The outer side of the pusher plate 8 is slidably connected to the inside of the mounting sleeve 4. The rear end of the pusher plate 8 contacts the front side of the package 5. The contact between the rear end of the pusher plate 8 and the front side of the package 5 allows the package 5 to expand and act on the pusher plate 8 in a timely manner.

[0032] The outer side of the sliding rod 7 is slidably connected to the inside of the mounting sleeve 4. The outer side of the sliding rod 7 is provided with a sharp edge, which can prevent the sliding rod 7 from rotating inside the mounting sleeve 4.

[0033] A push ring 18 is slidably connected to the outer side of the mounting rod 14. A push spring 19 is fixedly connected to the top of the push ring 18. The elastic force of the push spring 19 acts on the mounting base 15 through the push ring 18, providing a downward force to the mounting rod 14. This enhances the stability of the positioning when the positioning piece 16 engages with the positioning groove 17, and also prevents the shut-off button 20 from becoming misaligned.

[0034] The top end of the push spring 19 is fixedly connected to the inner top end of the mounting shell 2, and the bottom end of the push ring 18 is in contact with the top end of the mounting base 15.

[0035] The pressing block 9 is C-shaped, with the alarm button 11 and the off button 20 corresponding to the left and right ends of the front side of the pressing block 9, respectively. The C-shaped pressing block 9 allows the alarm button 11 and the off button 20 to be pressed directly.

[0036] When motor 1 is working, a large amount of heat is generated inside motor 1. However, if the heat of motor 1 becomes too high, the mercury 6 inside the encapsulation bladder 5 will expand, thereby pushing the pusher plate 8. The pusher plate 8 pushes the sliding rod 7 and the pressing block 9, causing the pressing block 9 to move forward. When the temperature reaches the critical value, the pressing block 9 will press the off button 20 and the alarm button 11. The alarm button 11 will activate the alarm light 12 and the alarm horn 13, which will emit light and alarm sound. The off button 20 will control motor 1 to turn off. When the temperature of motor 1 is lower than the critical value, the pressing block 9 will no longer press the off button 20, and motor 1 will be restarted to avoid damage to the permanent magnet inside motor 1 due to overheating. In some cases, even if the operating temperature of motor 1 exceeds the critical value, if it still needs to work, the positioning plate 16 can be pulled up by hand, causing the positioning plate 16 to rotate 180 degrees and engage with the positioning groove 17 again. The off button 20 will no longer be pressed by the pressing block 9.

[0037] By activating an alarm device and cutting off power to motor 1 when the operating temperature of the permanent magnet motor approaches or exceeds a certain value, the motor 1 is prevented from operating at temperatures above the critical value, thus ensuring the performance of motor 1 and avoiding the need for maintenance and replacement of the permanent magnets inside motor 1, thereby reducing maintenance costs. To this end, we propose a permanent magnet motor with a heat dissipation warning function.

[0038] Example 2

[0039] In this second embodiment, the other structures remain unchanged. The difference from the first embodiment is that the capsule 5 is elastic, and the mercury 6 is evenly distributed inside the capsule 5. The mercury 6 is evenly distributed inside the capsule 5, which allows the mercury 6 to act on the capsule 5 in a timely manner when it expands.

[0040] The outer side of the package 5 is in close contact with the inner wall of the mounting sleeve 4. The inner wall of the mounting sleeve 4 is smooth, which reduces wear.
