The present invention relates to the technical field of magnetic heat machines, and more particularly, to a magnetic heat power generation device.
A magnetic heat power generation device is capable of turning thermal energy into magnetic energy, through which magnetic energy can be further converted into mechanical energy to generate electricity. The traditional magnetic heat power generation device usually comprises a stator, which is provided with soft magnets, a rotor, which is provided with hard magnets, and a heating and cooling system which can heat and cool the soft magnets in the stator.
The structure of traditional magnetic heat power generation devices leads to the following shortcomings: First, in a traditional heating and cooling system, the soft magnets in the stator are respectively heated and cooled by a heating device and a cooling device. This arrangement requires a cumbersome structure, complicated pipeline and low integration level. Furthermore, the heating and cooling efficiency is seriously restricted by the complicated pipeline, resulting in a poor heating and cooling performance. Specifically, the heat transmission in this configuration is badly affected and the heat energy conversion rate is very low. Second, the peak value of the magnetic force fluctuates as the magnetic force of the soft magnet varies. In order to improve the conversion rate, a greater initial torque must be generated when the magnetic force of the soft magnet reaches the set value, thereby enabling the rotor to propel the output shaft to rotate and generate electricity. Thus, a retention magnet group is provided to the rotor and the support, avoiding the rotor from rotating under a low power output; the stationary retention magnet is fixed on the support to correspond to the moving retention magnet on the rotor. However, the magnetic heat power generation device is a multi-unit linkage configuration, such that the retention stations of the rotors may be imprecise after assembly. Under such circumstances, the filtering resistance of the retention magnet group can be sharply decreased, further lowering the conversion rate of the traditional magnetic heat power generation devices. Third, the hard magnet is connected to the rotor through a shielding case. A plurality of hard magnet fixing grooves is disposed on the rotor, and the two sides of the fixing grooves on the inner wall of the rotor are provided with locking elastic pieces. Additionally, the inner side of the upper end portion of the locking elastic piece includes a locking hook, the two side edges of the shielding case is snapped into the fixing groove, and the outer end of the shielding case is fixed through the locking hook. Accordingly, the mounting location of the hard magnet is difficult to regulate or replace. Furthermore, snap connection strength is inadequate, leading to low structural stability. The difficulty in mold-making of the locking hook is increased, resulting in a high manufacturing cost.
In conclusion, the shortcomings of traditional magnetic heat power generation devices are urgent problems that need to be solved for those skilled in this field.
The purpose of the present invention is to solve the technical problems relating to the unreasonable structure in the prior art, and provide a magnetic heat power generation device, which can precisely adjust the retention stations of the rotors, improve the heating and cooling speed of the soft magnets on the stator, enhance the heat energy conversion rate, simplify the overall structure, reduce the difficulty in mold-making of the rotor, and improve the structural stability.

Drawings and detailed embodiments are combined hereinafter to elaborate the technical principles of the present invention.

As shown in
The adjusting groove 141, which is arc-shaped, takes the shaft seat A110 having the same plane as the center. The two sides of the inner and outer edges of the adjusting groove 141 are provided with guiding plates 142 corresponding to the radian of the adjusting groove 141. The two sides of the inner end of the mounting bracket 150 are provided with locating plates 152, and the outer side edges of the two locating plates 152 are respectively disposed against the guiding plate 142 on each side.
The supporting beam 140 having the adjusting groove 141 is provided with a calibrated scale 143 for interacting with the mounting bracket 150. When the mounting bracket 150 moves along the adjusting groove 141, the calibrated scale can be used as a reference to rapidly regulate and eliminate the assembly errors produced between the main supports 100. Consequently, the retention stations of the rotors 200 can be adjusted into a consistent state, thereby improving the initial torque of the rotors 200.
The inner end surface of the mounting bracket 150 is provided with a fixing screw hole 153. A fixing bolt is inserted into the adjusting groove 141. The front end of the fixing bolt is inserted through the adjusting groove 141 and connected to the fixing screw hole 153. An adjusting hole 154 is disposed on the mounting bracket 150, and the center of the adjusting hole 154 is on the radial line of the shaft seat A110 having the same plane. The stationary retention magnet 151, which is cylinder-shaped, is provided with outer threads for interacting with the adjusting hole 154. The stationary retention magnet 151 moves along the adjusting hole 154 to change the distance to the moving retention magnet on the rotor 200. Thus, the retention damping force of the rotor 200 can be changed; therefore, each rotor 200 outputs consistently and synchronously, improving the initial torque of the rotors 200.
During use, the mounting bracket 150 takes the shaft seat A110 as the center to rotate along the adjusting groove 141. The stationary retention magnet 151 on the mounting bracket 150 then interacts with any moving retention magnet on the rotor 200. Thus, the retention station of the rotor 200 in a stationary state can be changed. When a plurality of magnetic heat power generation units is assembled into a magnetic heat power generation device, the assembly errors produced between the main supports 100 can be corrected through regulating the mounting bracket 150, thereby achieving consistent retention stations of the rotors 200. Consequently, the initial torque of the rotors 200 can be greatly improved and the conversion rate of the magnetic heat power generation device can be effectively enhanced.
The connection plate 130 is provided with a connecting base 131, and a plurality of fluid inlets 132 is disposed on the upper portion of the connection base 131. The lower portion of the connecting base 131 is provided with a large-caliber fluid outlet 133, and the fluid outlet 133 is respectively interconnected to a plurality of fluid inlets 132. The lower end of the connecting base 131 is provided with a fluid outlet pipe 134 that is connected to the fluid outlet 133. A plurality of fluid inlet pipes 310 is disposed on the upper portion of the stator 300, and a plurality of fluid outlet pipes 320 is disposed on the lower portion of the stator 300. The fluid outlet pipes 320 are respectively connected to the fluid inlets 132 on the connecting base 131. The soft magnets on the stator 300 are heated and cooled by the heating and cooling device 400, thereby changing the magnetic field to propel the rotors 200 to rotate. The heating and cooling fluids are discharged from the fluid outlet pipes 320 after flowing through the stator 300, and enter into the fluid inlets 132 on the connecting base 131. Subsequently, the heating and cooling fluids are discharged from the large-caliber fluid outlet 133. By improving the flowing speed of the heating/cooling fluids, the soft magnets' temperature changing speed is significantly increased. Consequently, the heat conversion rate of the magnetic heat power generation device of the present invention can be greatly improved.
