Description

Technical Field

[0001] This utility model relates to the field of shaft-driven generator technology, specifically a shaft-driven generator with cooling function. Background Technology

[0002] A shaft-driven generator is a device that converts mechanical energy into electrical energy using the principle of mechanical transmission. It is connected to a power source via a belt to drive the generator. The basic principle of a generator is based on electromagnetic induction. When a conductor moves in a magnetic field, an electromotive force is generated within the conductor, thus producing an electric current. The shaft-driven generator uses the rotational motion of the power source to drive the generator's rotor, thereby generating electrical energy. The generator is connected to the power source via a belt. The advantages of belt drives include flexible transmission ratios and the ability to isolate vibrations to a certain extent, reducing the direct impact of the power source on the generator. A shaft-driven generator is a type of generator that converts mechanical energy into electrical energy through a belt drive system. This design is typically used to connect to engines or other power sources to achieve power generation. This type of cooled shaft-driven generator combines the advantages of traditional generators with the effectiveness of a cooling system, making it suitable for various applications and ensuring stable and reliable operation in various environments.

[0003] Existing shaft-driven generators convert mechanical energy into electrical energy using mechanical transmission principles and connect to a power source via a belt to drive the generator. However, during prolonged transmission, the shaft belt can overheat, and excessively high temperatures can cause cracks on the belt surface, or even lead to belt breakage and system failure. To address these issues, the inventors have proposed a shaft-driven generator with a cooling function. Utility Model Content

[0004] To address the problem that existing shaft-driven generators convert mechanical energy into electrical energy using mechanical transmission principles and connect to a power source via a belt to drive the generator, which leads to belt overheating during prolonged transmission, excessively high temperatures can cause cracks on the belt surface and, in severe cases, belt breakage, resulting in system failure, this invention aims to provide a shaft-driven generator with a cooling function. By incorporating a shaft cooling component, both the shaft and the generator can be cooled simultaneously during transmission. This cooling component effectively reduces the operating temperature of the shaft and generator, preventing overheating. Lowering the temperature also slows down the aging rate of materials, thereby extending the service life of the shaft and the generator.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example: Figure 1-5 As shown, this utility model provides a shaft-driven generator with a cooling function, including a motor body 1, a shaft-driven connecting device 2, and a first fixing block 3. The first fixing block 3 is fixedly connected to the motor body 1. The shaft-driven connecting device 2 is fixedly installed on the outside of the motor body 1. A shaft-driven cooling assembly is fixedly installed on the outside of the shaft-driven connecting device 2. The shaft-driven cooling assembly includes a motor shaft 102, a cooling fan 104, a connecting shaft 202, and a connecting shaft belt 305.

[0025] A support plate 302 is fixedly installed on the outside of the motor body 1. A threaded rod 303 is fixedly installed on the outside of the support plate 302. A support base 301 is fixedly installed on the outside of the support plate 302. The threaded rod 303 is fixedly connected to the support base 301.

[0026] By adopting the above technical solution, the support fixing plate 302 and the support base 301 can be fixed by fixing the threaded rod 303 to the support base 301.

[0027] The first fixed block 3 is externally rotatably connected to the second rotating shaft 304, and the second rotating shaft 304 is externally movably connected to the connecting shaft belt 305, which is connected to the track of the connecting rotating shaft 202.

[0028] By adopting the above technical solution, the connecting shaft belt 305 is connected to the connecting rotating shaft 202 track, and the rotation of the second rotating shaft 304 can drive the connecting rotating shaft 202 to rotate.

[0029] The shaft-type connecting device 2 has a first dustproof net 201 fixedly installed externally, the connecting shaft 202 has a motor shaft 102 fixedly installed externally, the motor shaft 102 has a second fixing ring 204 fixedly installed externally, and the second fixing ring 204 has a slip ring 203 fixedly installed externally.

[0030] By adopting the above technical solution, a collector ring 203 is fixedly installed on the outside of the second fixing ring 204. The rotation of the collector ring 203, in conjunction with the brush 205, will generate a current in the coil of the generator according to Faraday's law of electromagnetic induction, and the current will be drawn out from the brush 205.

[0031] The shaft-type connecting device 2 is externally fixedly mounted with a third circular ring 208, and a brush 205 is externally fixedly mounted on the third circular ring 208. The brush 205 is in contact with the slip ring 203.

[0032] By adopting the above technical solution, the brush 205 and the slip ring 203 are bonded together.

[0033] A fixed ring 103 is fixedly installed on the outside of the motor shaft 102. The fixed ring 103 rotates outside the motor body 1. A brush 205 is fixedly installed on the outside of the motor shaft 102. A fixed copper strip 207 is fixedly installed on the outside of the brush 205. An air inlet 101 is fixedly installed on the outside of the motor body 1. The air inlet 101 is rotatably connected to the motor shaft 102.

[0034] By adopting the above technical solution, the air inlet 101 is rotatably connected to the motor shaft 102. The rotation of the motor shaft 102 can drive the second fixed ring 204 to rotate. The rotation of the motor shaft 102 can drive the cooling fan 104 to rotate, so that air can enter from the air inlet 101, pass through the motor body 1 and the shaft-type connecting device 2, and finally be discharged from the first dustproof net 201.

[0035] The brush 205 is externally fixedly mounted with the rotor 206, and the motor body 1 is externally fixedly mounted with the stator 105, which is in contact with the rotor 206.

[0036] By adopting the above technical solution, the stator 105 is attached to the rotor 206. The rotation of the rotor 206 will cause a change in the magnetic field around it. According to Faraday's law of electromagnetic induction, this change will generate a current in the coil of the generator.

[0037] A cooling fan 104 is fixedly installed on the outside of the connecting shaft 202. There are two sets of cooling fans 104, which are symmetrically distributed.

[0038] By adopting the above technical solution, the cooling fans 104 are arranged in two sets and are symmetrically distributed. The rotation of the motor shaft 102 can drive the cooling fans 104 to rotate, so that air can enter from the air inlet 101, pass through the motor body 1 and the shaft belt connection device 2, and finally be discharged from the first dustproof net 201. During the transmission process, the shaft belt and the generator can be cooled at the same time.

[0039] Working principle: When a shaft-driven generator with a cooling function is required, the power source is connected to the generator rotor via a belt or chain, which can transfer mechanical energy to the generator. The second rotating shaft 304 drives the connecting shaft belt 305 to rotate, which in turn drives the connecting shaft 202 to rotate. The connecting shaft 202 then drives the second fixed ring 204 to rotate, which in turn drives the motor shaft 102 to rotate the brush 205. The rotation of the brush 205 drives the rotor 206 to rotate. The rotation of the rotor 206 causes a change in the magnetic field around it. According to Faraday's law of electromagnetic induction, this change will generate a current in the generator coil and lead it out through the brush 205.

[0040] At the same time, the rotation of the motor shaft 102 can drive the second fixed ring 204 to rotate, and the rotation of the motor shaft 102 can drive the cooling fan 104 to rotate, allowing air to enter from the air inlet 101, pass through the motor body 1 and the shaft-type connecting device 2, and finally exit from the first dustproof net 201. During the transmission process, the shaft and generator can be cooled simultaneously. The cooling components can effectively reduce the operating temperature of the shaft and generator, prevent overheating, and slow down the aging rate of materials by reducing the temperature, thereby extending the service life of the shaft and generator.
