Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present invention belong to the protection scope of the present invention.

Fig. 1 is a schematic structural view of an embodiment of the fan-type generating set of the present invention.

As shown in Figure 1, the fan-type generator set 1 includes a first fan 10, a second fan 20, a power generating device 30 and a conversion device 40, the first fan 10 is connected with a first rotating device 11, and the second fan 20 is connected with a The second rotating device 21, the power generating device 30 converts the power generated by the first rotating device 11 and the second rotating device 21 into electric power, the conversion device 40 connects the first rotating device 11 and the second rotating device 21, and converts the first rotating device 11 The generated power is transmitted to the second rotating device 21 .

The working principle of the fan-type generator set 1 is that the air flow flows in the direction of the fan, driving the first fan 10 and the second fan 20 to rotate, and the first fan 10 and the second fan 20 drive the first rotating device 11 and the second rotating device respectively. The device 21 rotates, the converting device 40 concentrates the power generated by the first rotating device 11 and the second rotating device 21 , and the power generating device 30 uses the concentrated power to generate electricity. Therefore, the power of the airflow can be collected more through the two fans, and more power can be generated compared with a single fan, and then the collected power is concentrated through the conversion device 40, so that the collected power can be effectively used by the power generation device 30 , the power generating device 30 can generate more electric power. That is to say, the fan-type generator set 1 described in the present invention has higher power generation efficiency.

In addition, there may be more than two fans, and more fans may be provided, as long as each fan corresponds to a rotating device and a conversion device, and the power of the fan is transmitted to the same rotating device. In addition, the fan can also be a multi-stage fan with multiple sets of blades.

The first fan 10 and the second fan 20 preferably have opposite directions of rotation. That is, after the airflow passes through the first fan 10 , if the first fan 10 rotates forward, then when the airflow passes through the second fan 20 , the second fan 20 rotates reversely. For example, by making the blades of the first fan 10 and the blades of the second fan 20 deflect in different directions, the two fans can rotate in opposite directions when the airflow passes by. The counter-rotating fan can collect the power of the airflow more efficiently, generate greater torsional power, and finally the power generating device 30 can generate more electricity.

As a specific example, the first rotating device 11 includes a shaft sleeve 111, and the second rotating device 21 includes a rotating shaft 211 passing through the shaft sleeve 111. The rotating shaft 211 is connected with the power generating device 30 after passing through the shaft sleeve 111 . The first rotating device 11 further includes a bearing fixing member 112 for connecting the first fan 10 and the shaft sleeve 111 . The second selection device 21 further includes a shaft fixing member 212 for connecting the second fan 20 and the rotating shaft 211 . In addition, a bearing (not shown) is provided in the bearing fixing member 112 , and the rotating shaft 211 passes through the bearing and the shaft sleeve 111 in turn, and finally connects with the power generating device 30 .

Fig. 2 is a structural schematic view of the fan-type generator set in Fig. 1 without the fan.

The converting device 40 transmits the power generated by (the shaft sleeve 111 of) the first rotating device 11 to (the rotating shaft 211 of) the second rotating device 21 preferably through gear transmission. Specifically, the conversion device 40 includes a first driving gear 41 sleeved on (the shaft sleeve 111 of) the first rotating device 11, a second driving gear 42 sleeved on (the rotating shaft 211 of) the second rotating device 21, and A transmission mechanism 43 connecting the first driving gear 41 and the second driving gear 42 . The transmission mechanism 43 ensures that the first driving gear 41 and the second driving gear 42 rotate synchronously, so that the power generated by the bushing 111 can be smoothly transmitted and concentrated to the rotating shaft 211 .

The transmission mechanism 43 specifically includes a first transmission shaft 431 and a second transmission shaft 432. The second transmission shaft 432 is provided with a driven gear 433 and a transmission gear 434. The first transmission shaft 431 is provided with a borrow wheel 435. A driving gear 41 meshes, the transmission gear 434 meshes with the borrowing wheel 435 , and the borrowing wheel 435 meshes with the second driving gear 42 . Power sequentially passes through the first driving gear 41 , the driven gear 433 , the transmission gear 434 , the borrowing wheel 435 , and the second driving gear 42 to concentrate on the rotating shaft 211 .

Next, the movement of the fan, the rotating device and the gears will be described with reference to FIG. 1 , and the rotation direction of the fan is shown in the direction of the arrow in the figure. In FIG. 1 , the airflow direction is from right to left, and the first fan 10 rotates in the forward direction, thereby driving the bushing 111 and the first driving gear 41 to rotate in the forward direction, driving the driven gear 433 and the transmission gear 434 to rotate in the reverse direction, and the transmission gear 434 drives the borrowing wheel 435 to rotate in the forward direction, and the borrowing wheel 435 drives the second driving gear 42 to rotate in the reverse direction. Since the second fan 20 rotates in the reverse direction, it drives the rotating shaft 211 to rotate in the reverse direction, and the second driving gear 42 also rotates in the reverse direction. Therefore, the power generated by the sleeve 111 is transmitted to the rotating shaft 211 . In addition, if the power is expected to be transmitted smoothly, the number of teeth of each gear should cooperate with each other, so that the first driving gear 41 and the second driving gear 42 have the same speed (that is, the rotating shaft 211 and the shaft sleeve 111 have the same speed), for example, the first The number of teeth of driving gear 41, the second driving gear 42 is 2 times of the number of teeth of driven gear 433, transmission gear 434, borrowing wheel 435, and the number of teeth of driven gear 433, transmission gear 434, borrowing wheel 435 is identical. If the number of teeth is not matched, the rotation speeds of the rotating shaft 211 and the shaft sleeve 111 will be inconsistent, hindering the smooth transmission of force.

In the above description, the manner in which the power generating device 30 is connected to the rotating shaft 211 has been described, but in addition, the power generating device 30 may also be connected to the second transmission shaft 432 . Since the number of teeth of the first driving gear 41 and the second driving gear 42 is twice the number of teeth of the driven gear 433 and the transmission gear 434 respectively, the rotation speed of the second drive shaft 432 is twice the rotation speed of the rotating shaft 211, and a high-speed rotating shaft is required to generate electricity , the power generating device 30 can be optionally connected to the second transmission shaft 432 . In addition, the number of teeth of the first driving gear 41 and the second driving gear 42 is twice the number of teeth of the driven gear 433 and the transmission gear 434, which is only a specific example. The first driving gear 41 can also be 2 to 3 times the number of teeth of the driven gear 433. The second driving gear 42 can also be 2 to 3 times the number of teeth of the transmission gear 434. In addition, as required, the multiple relationship between the number of teeth of the first driving gear 41 and the number of teeth of the driven gear 433 and the ratio of the number of teeth of the second driving gear 42 and the transmission gear 434 The multiple can also be adjusted to other multiples.

Fig. 3 is a schematic diagram of the structure of the fan. In FIG. 3A , it is a diagram showing that the first fan 10 is placed in the air duct 50. As shown in FIG. In FIG. 3B, it is a figure which shows that the 2nd fan 20 is accommodated in the air duct 50. As shown in FIG.

The first fan 10 and the second fan 20 respectively include a first fan blade base plate 101 and a second fan blade base plate 201, and the first fan blade base plate 101 and the second fan blade base plate 201 are respectively provided with a first fan blade 102 and a second fan blade base plate. For the fan blades 202 , in order to achieve the effect that the airflow blows through the first fan 10 and the second fan 20 rotates in opposite directions, the deflection directions of the first fan blade 102 and the second fan blade 202 are different. Specifically, the first blade 102 is deflected counterclockwise in FIG. 3 and inward on the paper, and the second blade 202 is deflected clockwise in FIG. 3 and outward on the paper.

In this way, the spoiler 60 disturbs the airflow before the airflow passes through the fan, so that the airflow flows toward the fan more or faster.

As one of the specific implementations, as shown in FIG. 4 , the airflow direction is as indicated by the arrow. The fan-type generator set 1 of the present invention also includes an air duct 50, which is arranged on the first fan 10 and the second fan 20. The outer side of the spoiler 60 is arranged inside the air duct 50, and the spoiler 60 has a structure that gradually widens along the airflow direction. The front end of the spoiler is sharp and gradually widens. After the airflow enters the air duct 50, under the action of the spoiler 60, the channel side for the airflow is narrowed, so the airflow is accelerated. The spoiler cover 60 and the air duct 50 of this embodiment are suitable for the situation where the airflow blows directly from the front.

As another specific embodiment, as shown in FIG. 5 , the airflow direction is shown by the arrow. The fan-type generator set 1 of the present invention also includes a fan cylinder 50, which is arranged on the first fan 10 and the second fan 20. On the outer side, the spoiler 60 is arranged outside the air cylinder 50 , and the spoiler 60 has a structure narrowed toward the direction of the air cylinder 50 . In this way, an air inlet channel is formed between the spoiler 60 and the fan cylinder 50 .
