Description

Technical Field

[0001] This utility model relates to the field of magnetic flywheel technology, specifically a high-voltage magnetic flywheel with a directional reverse flow heat dissipation structure. Background Technology

[0002] Magnetic flywheel technology originated from the need to improve the efficiency of traditional mechanical systems. It was initially mainly used in the field of small engines, where the magnetic properties were used to optimize key functions such as ignition and speed stabilization. It has become one of the core components of equipment such as garden machinery, chainsaws and generators. With the growth of demand for energy storage and efficient utilization, magnetic levitation flywheel technology has emerged. It uses magnetic levitation bearings to achieve contactless support of the flywheel rotor, eliminate mechanical friction loss, and significantly improve speed and energy storage efficiency. It is widely used in fields such as power grid frequency regulation, rail transit braking energy recovery, UPS uninterruptible power supply and new energy vehicles.

[0003] The existing high-voltage coil magnetic flywheel with a directional reverse flow cooling structure is prone to blade damage during use. Because the weight on both sides of the magnetic flywheel is different after the blades are damaged, the balance of the magnetic flywheel will be affected when it rotates. The existing magnetic flywheel cannot replace the blades individually, but requires the entire magnetic flywheel to be replaced, which results in high maintenance costs. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a high-voltage magnetic flywheel with a directional reverse flow heat dissipation structure. This solves the problem that the blades on the magnetic flywheel are easily damaged during use. Because the weight on both sides of the magnetic flywheel is different after the blades are damaged, the balance of the magnetic flywheel will be affected when it rotates. Existing magnetic flywheels cannot replace the blades individually, but require the entire magnetic flywheel to be replaced, resulting in high maintenance costs.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-voltage magnetic flywheel with a directional reverse flow heat dissipation structure, comprising a base, a first blade on the top of the base, and multiple first blades, with a disassembly and assembly mechanism shared between the bottom of the multiple first blades and the base, a bearing block fixedly connected to the center of the top of the base, a bearing hole on the top of the bearing block, a groove on the bottom of the base, a heat dissipation groove on the top of the base, and bosses fixedly connected to both sides of the top of the base, with end caps on the top of the bosses, and the bosses and end caps sharing a common connection. The screw is threaded, and a second blade is fixedly connected to the top of the end cover. Heat sinks are fixedly connected to the surfaces of both the first and second blades. In this invention, an external bearing is installed and the magnetic flywheel is used through the bearing hole on the bearing block. The first blade can be replaced separately through the disassembly and assembly mechanism, saving maintenance costs. Furthermore, the end cover, boss, and screws allow the end cover to be opened to check the condition of the internal steel magnet and magnetic conductive block. The heat dissipation grooves and heat sinks allow the heat inside the magnetic flywheel to dissipate through a certain trajectory, achieving the purpose of cooling the magnetic flywheel and extending its service life.

[0008] Preferably, the bearing block has limiting grooves on both sides inside, and the limiting grooves are located inside the bearing hole. In this invention, the limiting grooves can prevent relative rotation between the bearing and the bearing block, making the connection between the bearing and the bearing block more stable and improving the stability of the magnetic flywheel during use.

[0009] Preferably, the heat dissipation groove is provided with guide grooves at both ends, one of the guide grooves is located on the top of the bearing block, and the other guide groove is located on the side of the base. In this invention, by setting the guide groove on the bearing block, heat can be better dissipated from the heat dissipation groove, and by setting the guide groove on the side of the base, cold air from the outside can be quickly passed through the heat dissipation groove and enter the surface of the magnetic flywheel, thereby achieving a better cooling and heat dissipation effect.

[0010] Preferably, the disassembly and assembly mechanism includes a slot, which is located at the top of the base, and the bottom of the first blade is inserted into the interior of the slot.

[0011] Preferably, the first blade has a first threaded hole on its front side, and the base has a second threaded hole on its side side. The second threaded hole is located on the front side of the slot, and a bolt is threadedly connected between the first threaded hole and the second threaded hole.

[0012] In this invention, when the first blade is damaged, it can be replaced by a disassembly and assembly mechanism. During replacement, the bolts are first removed from the first and second threaded holes, and then the bottom of the first blade is pulled out of the slot. After that, a new first blade is installed. During installation, the bottom of the new first blade is inserted into the slot, and then the bolts are used to fix them through the first and second threaded holes. With the disassembly and assembly mechanism, the first blade can be replaced individually, so that when the blade on the magnetic flywheel is damaged, it is not necessary to replace the entire magnetic flywheel, but only the first blade needs to be replaced. This saves maintenance costs, and the replacement operation is simple, convenient and quick.

[0013] Preferably, a steel magnet is placed on one side of the interior of one of the bosses, a magnetic block is placed on the other side of the interior of another boss, and a counterweight is placed inside the other boss. In this invention, by setting the counterweight, the weight on both sides of the magnetic flywheel can be balanced, so that its center is stabilized in the center position, thereby making the magnetic flywheel rotate more smoothly.

[0014] Preferably, one of the bosses has a through hole on one side, and one side of the magnetic block extends through the through hole to the outside of the boss. In this invention, the through hole allows the magnetic block to protrude to the outside of the boss, thereby enabling the magnetic flywheel to work normally.

[0015] (III) Beneficial Effects

[0016] This invention provides a high-voltage coiled magnetic flywheel with a directional reverse-flow heat dissipation structure. It has the following beneficial effects:

[0017] (I) The high-voltage coil magnetic flywheel with a directional reverse flow heat dissipation structure can be fixed and removed by bolts in the first and second threaded holes through the setting of the disassembly and assembly mechanism, thereby realizing the disassembly and installation of the first blade. This allows the first blade to be replaced individually, so that when the blade on the magnetic flywheel is damaged, it is not necessary to replace the entire magnetic flywheel, but only the first blade needs to be replaced, which saves maintenance costs and the replacement operation is simple, convenient and quick.

[0018] (II) The high-voltage coil magnetic flywheel with a directional reverse flow heat dissipation structure, through the setting of heat dissipation slots, heat dissipation fins and guide slots, allows the heat inside the magnetic flywheel to be dissipated through a certain trajectory, thereby achieving the purpose of cooling the magnetic flywheel and extending its service life. The setting of guide slots on the bearing block can better dissipate heat from the heat dissipation slots, and the setting of guide slots on the side of the base can allow cold air from the outside to quickly pass through the heat dissipation slots and enter the surface of the magnetic flywheel, thereby achieving a better cooling effect.

[0026] See Figures 1-5This utility model provides a technical solution: a high-voltage magnetic flywheel with a directional reverse flow heat dissipation structure, the structure of which includes a base 1, a first blade 2 on the top of the base 1, multiple first blades 2, a disassembly and assembly mechanism 3 shared between the bottom of the multiple first blades 2 and the base 1, a bearing block 4 fixedly connected to the middle of the top of the base 1, a bearing hole 5 on the top of the bearing block 4, a groove 6 on the bottom of the base 1, a heat dissipation groove 7 on the top of the base 1, bosses 8 fixedly connected to both sides of the top of the base 1, an end cap 9 on the top of the bosses 8, and screws 10 threadedly connected between the bosses 8 and the end caps 9. A second blade 11 is fixedly connected to the top. Heat sinks 12 are fixedly connected to the surfaces of the first blade 2 and the second blade 11. Specifically, the external bearing is installed and the magnetic flywheel is used through the bearing hole 5 on the bearing block 4. The first blade 2 can be replaced separately through the disassembly and assembly mechanism 3, saving maintenance costs. Through the end cover 9, the boss 8 and the screw 10, the end cover 9 can be opened to check the use of the steel magnet 15 and the magnetic conductor block 16 inside. Through the heat dissipation groove 7 and the heat sink 12, the heat inside the magnetic flywheel can be dissipated through a certain trajectory, achieving the purpose of cooling the magnetic flywheel and extending the service life of the magnetic flywheel.

[0027] The bearing block 4 has a limiting groove 13 on both sides inside. The limiting groove 13 is located inside the bearing hole 5. Specifically, the limiting groove 13 can prevent relative rotation between the bearing and the bearing block 4, making the connection between the bearing and the bearing block 4 more stable and improving the stability of the magnetic flywheel during use.

[0028] The heat dissipation groove 7 has guide grooves 14 at both ends. One guide groove 14 is located on the top of the bearing block 4, and the other guide groove 14 is located on the side of the base 1. Specifically, the guide groove 14 on the bearing block 4 can better dissipate heat from the heat dissipation groove 7, and the guide groove 14 on the side of the base 1 can allow cold air from the outside to quickly pass through the heat dissipation groove 7 and enter the surface of the magnetic flywheel, thereby achieving a better cooling effect.

[0029] The disassembly and assembly mechanism 3 includes a slot 31, which is located on the top of the base 1, and the bottom of the first blade 2 is inserted into the inside of the slot 31.

[0030] The first blade 2 has a first threaded hole 32 on its front side, and the base 1 has a second threaded hole 33 on its side. The second threaded hole 33 is located on the front side of the slot 31, and the first threaded hole 32 and the second threaded hole 33 are connected by a bolt 34.

[0031] Specifically, when the first blade 2 is damaged, it can be replaced by the disassembly and assembly mechanism 3. During replacement, the bolt 34 is first removed from the first threaded hole 32 and the second threaded hole 33, and then the bottom of the first blade 2 is pulled out of the slot 31. After that, a new first blade 2 is installed. During installation, the bottom of the new first blade 2 is inserted into the slot 31, and then the bolt 34 is used to fix them through the first threaded hole 32 and the second threaded hole 33. With the disassembly and assembly mechanism 3, the first blade 2 can be replaced individually, so that when the blade on the magnetic flywheel is damaged, it is not necessary to replace the entire magnetic flywheel, but only the first blade 2 needs to be replaced. This saves maintenance costs, and the replacement operation is simple, convenient and quick.

[0032] One of the protrusions 8 has a steel magnet 15 placed on one side inside, another protrusion 8 has a magnetic block 16 placed on the other side inside, and the third protrusion 8 has a counterweight 17 placed inside. Specifically, by setting the counterweight 17, the weight on both sides of the magnetic flywheel can be balanced, so that its center is stabilized in the center position, thereby making the magnetic flywheel rotate more smoothly.

[0033] One of the bosses 8 has a through hole 18 on one side, and one side of the magnetic block 16 extends through the through hole 18 to the outside of the boss 8. Specifically, the through hole 18 allows the magnetic block 16 to protrude to the outside of the boss 8, thereby enabling the magnetic flywheel to work normally.
