A load-eliminating counter-torque generator

Abstract

This utility model discloses a load-eliminating counter-torque generator, including a generator housing, a central shaft inside the generator housing, a first turntable and a second turntable mounted at both ends of the central shaft, a counter-torque mechanism mounted on the first turntable, and a connecting mechanism mounted on the generator housing. This utility model relates to the field of generator technology. When this device is connected to a load, the torque generated by the rotation of the shaft and central shaft causes the bearing pulleys to slide at the arc-shaped grooves of the first and second turntables. This, in conjunction with the positioning rod and the arc-shaped retaining ring, drives the rotor winding to slide along the central shaft. At the same time, the wire rope transfers the automatic torque of the rotor winding to the pressure sleeve of the central shaft through the bearing pulleys. As the rotation continues, the wire rope will be continuously tightened, and the counter-torque will gradually increase. Therefore, the counter-torque will not hinder the rotation of the rotor winding, thus reducing the impact on power generation efficiency.

Description

Technical Field

[0001] This utility model relates to the field of generator technology, specifically to a load-eliminating counter-torque generator. Background Technology

[0002] A generator is a mechanical device that converts other forms of energy into electrical energy. The basic structure of a generator consists of two parts: a rotor and a stator. The rotor is located in the central cavity of the stator and is equipped with magnetic poles that generate a magnetic field. When the prime mover drives the rotor to rotate, mechanical energy is transferred. As the rotor rotates at high speed, the magnetic poles interact with the stator windings. The magnetic field cuts the conductors of the stator windings, generating an induced electromotive force, thus converting mechanical energy into electrical energy.

[0003] Currently, in traditional generators, the internal magnetic pole rotor cannot slide and moves together with the central shaft. When the generator rotor is connected to a load, it generates a torque opposite to that of the original generator rotor. As the load current increases, the braking torque also increases until the rotor stops. Therefore, the generated braking torque hinders the rotor's rotation and affects the power generation efficiency. In view of this, it is essential to design a generator that eliminates load counter-torque to solve this problem. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a load-eliminating reverse torque generator, which solves the problem that in existing generators, the internal magnetic pole rotor cannot slide and moves with the central shaft. As a result, when the generator rotor is connected to a load, it generates a torque opposite to that of the original generator rotor. Furthermore, as the load current increases, the braking torque also increases until the rotor stops. Therefore, the generated braking torque hinders the rotor's rotation and affects the power generation efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a load-eliminating counter-torque generator, comprising a generator housing, a central shaft disposed inside the generator housing, shaft rods fixedly connected to both sides of the central shaft, a first turntable frame and a second turntable frame mounted at both ends of the central shaft, with the outer wall of the second turntable frame fitting against the central shaft, a counter-torque mechanism mounted on the first turntable frame, a connecting mechanism mounted on the generator housing, and pressure sleeves connected to the outer walls of both ends of the shaft rods, with the outer walls of the pressure sleeves fitting against the pressure fixing holes of the first turntable frame and the second turntable frame respectively;

[0006] The countermeasure mechanism includes several arc-shaped retaining rings that fit against the outer wall of the central shaft axis, and both ends of the arc-shaped retaining rings are fitted against the second turntable frame. A positioning rod is slidably connected to the through hole of the arc-shaped retaining ring, and both ends of the positioning rod are connected to bearing pulleys. The bearing pulleys are slidably connected to the arc-shaped grooves of the first and second turntable frames. A steel wire rope is wound around the middle of the bearing pulley, and the end of the steel wire rope away from the bearing pulley passes through the through hole of the first turntable frame and is wound and connected to the pressure sleeve.

[0007] Preferably, the connection mechanism includes a stator core fixed to the inner wall of the generator housing, a stator winding is wound around the inner wall of the stator core, and a plurality of rotor slot wedges are machined on the outer wall of the arc-shaped retaining ring, and rotor windings are wound around the rotor slot wedges.

[0008] Preferably, the generator housing is bolted to both ends with a front cover and a rear cover, and both the front cover and the rear cover are rotatably connected to the shaft via bearings.

[0009] Preferably, a pulley is fixed to the outer wall of the shaft.

[0010] Preferably, a wiring box and a pair of supports are fixedly connected to the front end and bottom end of the generator housing, respectively.

[0011] Preferably, a plurality of connecting rods are fixed to the outer wall of the first turntable frame, and a first strong magnet is fixed to the end of the connecting rod away from the first turntable frame. The outer wall of the first strong magnet is provided with a rubber sleeve, and the outer wall of the rubber sleeve is bonded to the inner wall of the generator housing. A second strong magnet is provided inside the rubber sleeve. Beneficial effects

[0012] This utility model provides a load-eliminating torque generator, which has the following beneficial effects:

[0013] A bearing pulley can be installed on the positioning rod that limits the arc-shaped retaining ring. A steel wire rope is wound around the bearing pulley, and the other end of the steel wire rope is connected to the shaft of the central shaft. When this device is connected to a load, the torque generated by the rotation of the shaft and the central shaft will cause the bearing pulley to slide at the arc-shaped groove of the first and second turntables. This, in conjunction with the positioning rod and the arc-shaped retaining ring, drives the rotor winding to slide along the central shaft. At the same time, the steel wire rope transfers the automatic torque of the rotor winding to the pressure sleeve of the central shaft through the bearing pulley. As the rotation progresses, the steel wire rope will continue to tighten, and the braking torque will gradually increase. Therefore, the braking torque will not hinder the rotation of the rotor winding, thus reducing the impact on power generation efficiency.

[0014] Meanwhile, several rotor slot wedges are machined on the outer wall of the arc-shaped retaining ring, and rotor windings are wound and connected on the rotor slot wedges. Compared with the traditional rotor magnetic poles, this structure reverses the stator windings, using the outer diameter circumferential winding as the inner diameter coil winding of the generator rotor. This results in a stronger magnetic field cutting effect with the stator core and stator windings, and the generated power can be greatly improved, thus achieving better performance.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a load-eliminating counter-torque generator, including a generator housing 1, a central shaft 2 is provided inside the generator housing 1, and shaft rods 3 are fixedly connected to both sides of the central shaft 2. A first turntable frame 4 and a second turntable frame 5 are installed at both ends of the central shaft 2, and the outer wall of the second turntable frame 5 is in contact with the central shaft 2. A counter-torque mechanism is installed on the first turntable frame 4. A connecting mechanism is installed on the generator housing 1. Pressure sleeves 14 are connected to the outer walls of both ends of the shaft rods 3, and the outer walls of the pressure sleeves 14 are respectively in contact with the pressure fixing holes of the first turntable frame 4 and the second turntable frame 5.

[0022] The countermeasure mechanism includes several arc-shaped guard rings 6 that are attached to the outer wall of the central shaft 2 along the axis, and both ends of the arc-shaped guard rings 6 are attached to the second turntable frame 5. A positioning rod 7 is slidably connected to the through hole of the arc-shaped guard ring 6. Both ends of the positioning rod 7 are connected to bearing pulleys 8, and the bearing pulleys 8 are slidably connected to the arc-shaped grooves of the first turntable frame 4 and the second turntable frame 5. A steel wire rope 9 is wound around the middle of the bearing pulley 8, and the end of the steel wire rope 9 away from the bearing pulley 8 passes through the through hole of the first turntable frame 4 and is wound around the pressure sleeve 14.

[0023] The second turntable frame 5 can block the four arc-shaped guard rings 6. Through holes are machined inside the arc-shaped guard rings 6, and positioning rods 7 are set at these through holes to limit their movement. Four arc-shaped grooves and through holes are machined inside the first turntable frame 4 and the second turntable frame 5. The bearing pulley 8 can move in these arc-shaped grooves, and the steel wire rope 9 can pass through these through holes. This, together with the positioning rod 7, drives the arc-shaped guard rings 6 to slide on the outer wall of the central shaft 2. At the same time, pressure fixing holes are machined inside the first turntable frame 4 and the second turntable frame 5. In this way, the pressure sleeve 14, together with these pressure fixing holes, can connect and fix the first turntable frame 4 and the second turntable frame 5 to the shaft 3 of the central shaft 2.

[0024] In this embodiment, the connection mechanism is further configured such that the stator core 12 is fixedly connected to the inner wall of the generator housing 1, the inner wall of the stator core 12 is wound with stator windings 13, and the outer wall of the arc-shaped retaining ring 6 is machined with a plurality of rotor slot wedges 10, and rotor windings 11 are wound on the rotor slot wedges 10.

[0025] A rotor can be formed by the rotor slot wedge 10, rotor winding 11, arc-shaped retaining ring 6 and central shaft 2. Compared with the traditional rotor magnetic poles, this structure reverses the stator winding 13, with the outer diameter circumferential winding serving as the inner diameter coil winding of the generator rotor. This results in a stronger magnetic field cutting effect with the stator core 12 and stator winding 13, and the generated power can be greatly improved.

[0026] In this embodiment, the generator housing 1 is further configured such that the two ends are respectively threadedly connected to a front cover 15 and a rear cover 16 by bolts, and both the front cover 15 and the rear cover 16 are rotatably connected to the shaft 3 by bearings.

[0027] In this embodiment, the outer wall of the shaft 3 is further configured to be fixed with a pulley 17.

[0028] In this embodiment, the front end face and the bottom end face of the generator housing 1 are respectively fixed with a circuit box 19 and a pair of supports 18.

[0029] In this embodiment, a plurality of connecting rods 20 are fixedly connected to the outer wall of the first turntable frame 4, and a first strong magnet 21 is fixedly connected to the end of the connecting rod 20 away from the first turntable frame 4. The outer wall of the first strong magnet 21 is provided with a rubber sleeve 22, and the outer wall of the rubber sleeve 22 is bonded to the inner wall of the generator housing 1. A second strong magnet 23 is provided inside the rubber sleeve 22.

[0030] Four connecting rods 20 and a first strong magnet 21 are arranged on the outer wall of the first turntable frame 4. The connecting rods 20 are distributed in a ring at equal intervals with the center of the first turntable frame 4 as the center point. A second strong magnet 23 wrapped with a rubber sleeve 22 is arranged outside the first strong magnet 21. When the first turntable frame 4 rotates, it will drive the first strong magnet 21 to rotate through the connecting rods 20. The first strong magnet 21 and the second strong magnet 23 will then generate a repulsive force, thereby achieving the assist effect. It can also further reduce the load counter torque, making the coil generator power effect more perfect and increasing the generator power effect.

[0031] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0032] Example: When this device is needed, a bearing pulley 8 can be installed on the positioning rod 7 that limits the arc-shaped retaining ring 6. A steel wire rope 9 is wound and connected to the bearing pulley 8, and the other end of the steel wire rope 9 is connected to the shaft 3 of the central shaft 2. When this device is connected to a load, as the shaft 3 and the central shaft 2 rotate, the generated torque will cause the bearing pulley 8 to slide at the arc-shaped groove of the first turntable frame 4 and the second turntable frame 5. This, in conjunction with the positioning rod 7 and the arc-shaped retaining ring 6, drives the rotor winding 11 to slide along the central shaft 2. At the same time, the steel wire rope 9 transfers the automatic torque of the rotor winding 11 to the pressure sleeve 14 of the central shaft 2 through the bearing pulley 8. As the rotation continues, the steel wire rope 9 will be continuously tightened, and the braking torque will gradually increase. Therefore, the braking torque will not hinder the rotation of the rotor winding 11, thus reducing the impact on power generation efficiency.

[0033] Meanwhile, several rotor slot wedges 10 are machined on the outer wall of the arc-shaped retaining ring 6, and rotor windings 11 are wound and connected on the rotor slot wedges 10. Compared with the traditional rotor magnetic poles, this structure reverses the stator windings 13, using the outer diameter circumferential winding as the inner diameter coil winding of the generator rotor. This results in a stronger magnetic field cutting effect with the stator core 12 and stator windings 13, which greatly increases the power output and thus improves the performance.
