Detailed Description

According to the invention, the figure 1 shows a schematic three-dimensional view of a linear wind generating set according to the technical characteristics of the invention, wind enters a wind wheel (2) from the left side of the figure, the wind wheel is rotated to force the wind wheel to form a rotor, and the rotor and a winding of a wheel frame (1) provided with a winding generate magnetic line cutting motion, so that induced current is generated on the winding, passes through an electric module (11), passes through a rectifying circuit and a filter circuit, and is transmitted after voltage modulation is carried out through a power transmission circuit.

According to the characteristic diagram of the invention, as shown in the top view of the wheel seat of fig. 8, when wind power is applied, the wind direction device is always positioned on the downwind surface (50), the wind direction device is fixed with the wheel seat through the wind direction rod, and the vertical plane of the wind direction rod and the wind direction device is vertical to the vertical plane of the wheel frame, so that the wheel frame is ensured to drive the wind wheel to realize the windward surface (80).

According to the characteristic of the invention, fig. 2 is a schematic axial center section three-dimensional view of a linear wind generating set, in a specific occasion, a wind direction device is used as a sensor, an intelligent control mode is adopted, and a wind direction rotating mechanism (10) is utilized to force a wheel frame and a wind wheel to be at a windward angle.

In addition, the wheel ribs (7) are used as a connecting structure of the wheel frame and the wind wheel, the wind wheel is restrained from doing radial rotating motion in a certain space, when the wind wheel is used in a low wind area, the diameter of the wheel frame is smaller, the diameter of the wind wheel is smaller, the rotating speed is higher, the number of the adopted wheel ribs is larger, and the radial width of the wheel ribs is smaller. When the wheel frame is used in a strong wind area, the diameter of the wheel frame is larger, the diameter of the wind wheel is larger, but the rotating speed is slower, the number of adopted wheel ribs is less, the radial width of the wheel ribs is larger, and the axial width is larger.

Meanwhile, the wheel seat (5) is used as a wheel frame, a wind wheel and a whole running mechanical supporting structure, the mechanical strength of the wheel seat is different from that of a low wind area and a high wind area, the whole low wind area generator is small, the wheel seat is small, the outer wall (503) of the wheel seat is thin, and the fixed wheel frame structure (501) is small.

According to the characteristics of the invention, the three-dimensional schematic view of the wind wheel in fig. 5 shows that the fan blade (21) is the only unit for absorbing wind energy, and the fan blade has a spiral structure, so that the axial kinetic energy is converted into radial rotation energy, and the magnetic induction structure (108) is driven to move.

The adopted anti-skid structure (23) ensures that the magnetic induction structure always synchronously rotates with the impeller connecting structure (24) to prevent the loss of the rotating energy.

The wind wheel core (25) is the only unit for bearing the gravity of the wind wheel, and after the wind wheel rotates completely, under the influence of high rotating speed and induction magnetic force, the wind wheel core can automatically overcome the self weight of the wind wheel, the contact surface of the wind wheel core and the core rod is gradually reduced, and the wind wheel core is suspended in the radial direction, so that the mechanical abrasion is reduced.

Meanwhile, the fan blades near the wind wheel core are narrow and thin, and the volume of the wind wheel core is small, so that the weight of the unit is reduced.

The fan blades are circular in shape and are wide and thick at the round edges and are fully and fixedly connected with the impeller connecting structure (24), so that air flow generated by the centrifugal effect of the rotation of the fan blades slides to the edges and is converted into radial kinetic energy by the wind wheel ring (22) of the impeller connecting structure, and the utilization rate of the kinetic energy is improved.

The fan blade width near the wind wheel ring is large, the front-back pressure difference formed by the airflow is larger, the wind wheel ring rotation starting torque is more favorably generated, and the wind wheel ring rotation starting torque is suitable for the characteristic that the unit power generation in a low wind area is easy to start.

According to the characteristics of the invention, as shown in the axial center section of the wheel frame in the schematic perspective view of fig. 3, a certain gap is formed between a magnetic induction structure (108) on a rotor of a wind wheel and an isolation ring (107) of a stator in the wheel frame, so that the wind wheel is ensured not to block the wheel frame when rotating, but the magnetic line of force structure can be induced not to be influenced, and the center of cutting the magnetic line of force is positioned at the geometric center of the whole wheel frame, thereby eliminating the possibility of gravity imbalance of a unit.

The wind power enters the wind wheel, and the wind power at the edge of the wheel frame enters the impeller area under the flow guidance of the wind collecting structure (110), so that the range of catching wind energy on the windward side is improved.

When the residual wind leaves the wind wheel, the residual wind behind the wheel frame cannot form vacuum under the action of the rectifying structure (106), so that the possibility of damage of air explosion of the wheel frame is eliminated, and the service life of the unit structure is prolonged.

The protection of the wiring harness connection of the silicon steel sheet (104) and the winding (105) is realized by a circular cavity formed by the front framework (102), the rear framework (1090), the protection structure (103) and the isolation ring (107), and the filler (111) is used as an auxiliary material, belongs to secondary protection and simultaneously enhances the mechanical strength.

Through wheel frame mounting (101), will gather wind structure, wheel muscle, the cavity of constituteing, wheel muscle, rectification structure are fixed, have formed whole stator structure, have realized the possibility of engineering spare part field assembly to this reduces the engineering construction degree of difficulty.

In order to reduce the weight of the unit, except for a wheel seat, a wheel rib, a winding, a framework, a silicon steel sheet and a magnetic induction structure, other materials can be light, so that the engineering quantity of installing a crane of the unit is reduced.

According to the characteristic of the invention, as shown in a three-dimensional schematic diagram of a section structure of an axial center of a wheel core in fig. 4, a wind wheel core (301) is positioned at the middle section of the axial direction of the wheel core and belongs to a rotor, and a core rod (302) penetrates through the center hole of the wind wheel core and is locked with an end cover (305) of a wheel rib (7) auxiliary piece (304) of a lining (303) by a nut (306) and a reverse nut (308), so that the fixation and integration of a stator at the wheel core are realized, particularly, the reverse nut is adopted, the synchronous vibration of the rotation of the wind wheel and the spiral direction of a conventional nut is prevented from generating isotropic loosening, and the stability of a unit is improved.

According to the characteristics of the invention, as shown in the three-dimensional schematic view of the wind wheel core in fig. 6, the fan blades (21) are all embedded in the fan blade grooves (254) of the wind wheel core, so that a plurality of fan blades and the wind wheel ring form an integrated rotor structure, and the beating impact strength of the fan blades for resisting disordered wind power is improved.

A round hole (251) is formed in the center of the wind wheel core, and the diameter of the round hole is larger than that of the core rod (302), so that a certain fit clearance is reserved, the wind wheel can be ensured to rotate freely, and the wind wheel can be restrained within a certain range.

The wind wheel core is provided with the bush through the bush fixing structure (252), so that the mechanical wear surface for starting and stopping the rotation of the wind wheel is reduced, and meanwhile, the mechanical wear coefficient is reduced to the maximum extent, so that the mechanical energy loss is reduced.

The abdicating round tables (253) at the two axial ends of the wind wheel core have larger structural size, and provide enough space for the auxiliary piece (304) to adopt soft materials compared with the lining so as to absorb the resonance energy of the wind wheel, thereby reducing the mechanical vibration noise and improving the stability of the unit.

By adopting the fan blade groove structure, the processing difficulty can be reduced, and the possibility of assembling the accessories on a construction site can be realized, so that the difficulty of unit transportation and engineering installation is reduced.

According to the characteristics of the invention, the three-dimensional schematic diagram of the axial center section of the bushing in fig. 9 and the transparent schematic diagram of the side view of the bushing in fig. 10 show that the most critical part of the whole unit of the bushing has smaller volume, lower processing difficulty and ensured dimensional precision.

In the assembling process, if the inner ring (3032) or the outer ring (3031) of the bushing possibly has an error that the matching is not optimal, the step (30311) of the outer ring of the bushing or the step (30321) of the inner ring of the bushing can be disassembled and assembled once, so that the implementation difficulty of a unit is reduced, and the investment cost is reduced.

According to the characteristic of the invention, as shown in the axial center section of the end cover in the figure 11, the end cover adopts an outer cambered surface (3051) to reduce the impact of the windward side and also guide the wind power to a wind wheel ring area, so that the wind energy utilization rate of the windward side is improved.

The concave position round plane (3054) of the end cover eliminates the possibility of blocking the rotation of the wind wheel core when the end cover is locked.

The outer side of the end cover is provided with a platform (3055) which is beneficial to a nut locking moment contact surface, so that the stability of the unit is improved.

The end cover is a key part for combining the wheel core and the wind wheel core, is also a key part for ensuring the clearance and free rotation of the stator and the rotor, has higher requirement on mechanical strength, and requires weather corrosion resistance and sunlight radiation resistance in surface treatment, thereby improving the stability and the service life of the unit.

According to the characteristic of the invention, as shown in the working principle block diagram of the interior of the electrical module of fig. 12, after wind energy forms induced voltage on a stator winding (B), the generated current is processed by a rectifier circuit (C) and a filter circuit (D), and then is transmitted by a direct current buck/boost circuit (E) or an inverter alternating current circuit (G) through a power transmission circuit (F), each unit in the process is monitored and controlled by a central control circuit (a) through instructions, and the central control circuit exchanges data with the outside through a data duplex radio frequency circuit (H) and an antenna, so as to realize intelligent power control.

During the breeze, central authorities' management and control circuit (A) detect unable direct transmission electric power, then begin the energy storage through energy storage circuit, and the retransmission is after reaching certain electric energy, the electric power of intermittent type nature transmission promptly.

In addition, when the frost weather is met, the energy storage circuit works to process the frost-affected part of the frost weather.

When thunderstorm weather, the central control circuit (A) starts a lightning protection circuit to start working and disconnect other circuits so as to ensure the discharge of thunder and lightning.

When the wind is strong, the central control circuit obtains severe parameters or weather forecast through the sensor, and cuts off the rectification circuit in advance, so that the electricity is prevented from being burnt by overhigh voltage and current.

When the unit encounters an unrecoverable disaster, the central control circuit (A) detects a key signal and sends an emergency call signal to the remote interface by using the energy storage circuit.

Because the winding layout is enlarged to the unit wheel frame, realized series distribution, obviously increased insulating space moreover, and heat dissipation space to the voltage that produces is higher, after the rectification is filtered, can improve more, with this realization power supply direct transmission, and the necessity of omitting secondary boost circuit engineering reduces the input cost with this.

Because the winding layout is enlarged by the wheel frame of the unit, the single-turn series connection continuous boosting distribution can be realized, namely, the voltage is higher after the single-phase rectification filtering, so that the possibility of direct high-voltage power transmission without the need of secondary boosting circuit engineering is realized.

The intelligent electric power management and control software program monitors the running parameters of the units, monitors a plurality of distributed units, effectively matches user parameters, collects and predicts daily safety parameters, and accordingly realizes field regulation and control and remote management and control.

The parameters in the monitoring process are not limited to wind parameters, weather parameters, voltage peak values, power generation duration, electric power degrees, fault positions, fault times, unit states and unit positions.

Various other modifications and changes may be made by those skilled in the art based on the above teachings and concepts, and all such modifications and changes are intended to fall within the scope of the present invention as defined in the appended claims.
