Description
Technical Field
The invention relates to the field of wind power generation, in particular to a large-caliber wind generating set.
Background
The wind power generator is composed of a tower, a generator, blades and the like, and is power equipment for converting kinetic energy of wind into electric energy. In the prior art, in order to increase the power of a wind generating set, the windward area of a blade needs to be increased as much as possible, namely the length and the width of the blade are increased, however, as the wind field for installing the wind generating set is mostly distributed in mountainous areas, plateaus, oceans or islands, the overlarge blade brings great difficulty in transportation and installation, and the material, processing technology and precision requirements are higher and higher when the length of the blade is increased, so that the difficulty in expanding production is brought, and the wind generating set is not suitable for families, middle and small-sized agricultural pastures. In order to adapt to the geographical distribution of wind energy in China, the utilization rate of the wind energy is required to be improved on the premise of not increasing the size of the paddle. How to design a small-size blade wind driven generator which is easy to install and transport and has high wind energy utilization rate is an urgent need.
Disclosure of Invention
The invention aims to provide a wind driven generator which is small in size of blades and convenient to mount and transport, and the wind driven generator can remarkably improve the wind utilization rate.
The technical scheme adopted by the invention is as follows: a wind generating set comprises a generator, a shell part and a blade part, wherein the blade part comprises a blade and a blade rotating disk, the blade rotating disk is connected with an input shaft of the generator, the shell part comprises a conical air guide sleeve, the bottom of the air guide sleeve corresponds to the position of the blade, and the generator is fixed with the air guide sleeve in the air guide sleeve.
The invention has the beneficial effects that: the invention has the conical air guide sleeve, and can guide the wind power originally blowing to the position of the generator (and the maximum diameter area of the air guide sleeve) to the position of the blade, so that the smaller-sized blade can drive the generator, and compared with a large-caliber wind power generator, the invention has the advantages of simplified production process and convenient installation, transportation and maintenance; the conical structure of the air guide sleeve increases the torque of wind force acting on the blade, and the efficiency is greatly increased under the same wind force; the air guide sleeve is a thin-shell cover body, the direction of the fan can be adjusted while the air guide sleeve conducts flow, the top of the conical air guide sleeve always points to the direction of wind blowing, and a tail vane in a wind driven generator in the prior art can be replaced. The generator is arranged in the air guide sleeve, so that the service life of the generator is greatly prolonged.
The invention is further described with reference to the following figures and detailed description.
Drawings
FIG. 1 is a schematic structural diagram of the present invention;
fig. 2 is an enlarged schematic view of region a in fig. 1.
In the attached drawing, 1 is a blade, 2 is a connecting shaft, 3-1 is a flow guide cover, 3-2 is a chassis, 3-2-1 is a supporting part, 4 is a counterweight body, 5 is a generator, 6 is a blade rotating disk, 7 is a baffle disk, 8 is a ball, 9 is a connecting disk, and 10 is a universal joint.
Detailed Description
Referring to the attached drawings 1 and 2, the wind generating set comprises a generator 5, a shell part and a blade part, wherein the blade part comprises a blade 1 and a blade rotating disk 6, the blade rotating disk is connected with the input shaft part of the generator, the shell part comprises a conical air guide sleeve 3-1, the bottom of the air guide sleeve 3-1 corresponds to the position of the blade 1, and the generator 5 is fixed with the air guide sleeve 3-1 in the air guide sleeve 3-1. Here, the tip of the pyramid is taken as the top, not the top in the up direction in the drawing, as follows.
In the embodiment, the shell further comprises a connecting disc 9 and a baffle disc 7, the shell further comprises a chassis 3-2, one side disc surface of the chassis 3-2 is fixedly connected with the bottom of the air guide sleeve 3-1, a supporting part 3-2-1 with a round pipe body is protruded on the other side disc surface of the chassis 3-2, the baffle disc 7 is fixedly connected with the supporting part 3-2-1, the paddle rotating disk 6 is arranged between the chassis 3-2 and the baffle disk 7 and is rotationally connected with the supporting part 3-2-1, a ball 8 is arranged between the baffle disk 7 and the paddle rotating disk 6, the connecting disk 9 is fixedly connected with the paddle rotating disk 6, the connecting disc 9 is connected with the input shaft of the generator 5 through the connecting shaft 2 passing through the supporting part, and universal joints 10 are arranged between the connecting shaft 2 and the connecting disc 9 and between the connecting shaft 2 and the rotor part of the generator 5.
When the wind guide cover type wind power generator works, when wind guided by the wind guide cover 3-1 blows to the blades 1, the blade rotating disc 6 drives the connecting disc 9 to rotate, the connecting disc 9 transmits rotation to a speed changer (not shown) through the connecting shaft 2, and the speed changer converts low rotating speed of the connecting disc 9 into high-speed rotation to drive the power generator to generate power. The paddle 1 is not directly connected with an input shaft of the generator 5, but indirectly connected by using structures such as the paddle rotating disc 6, the connecting disc 9, the universal joint 10 and the like as buffering, so that the high-speed rotation is ensured not to shake, and the safety and the reliability are greatly improved.
In the embodiment, in order to make the small-sized wind driven generator operate in a balanced manner, a balance weight body 4 for balancing the gravity center of the shell is arranged in the top of the air guide sleeve 3-1. After the counterweight body 4 is added, the gravity center moves forwards, so that the function of adjusting and steering the air guide sleeve 3-1 is better. The shape of the air guide sleeve 3-1 can be improved to improve the adjusting and steering effect of the air guide sleeve 3-1, for example, the shape of the air guide sleeve 3-1 is preferably a rectangular pyramid, the side surface of the air guide sleeve 3-1 facing to the symmetrical plane of the structure in the vertical direction can be further smoothly closed, and the rear end of the air guide sleeve 3-1 keeps the original shape. In order to improve the heat dissipation effect, the air guide sleeve 3-1 can be provided with a shutter heat dissipation hole with a hole facing the bottom of the air guide sleeve 3-1.
