Problems solved by technology

In this method, the kite needs to tow a large number of cables, generators, propellers and other equipment, so it has the disadvantages of heavy load, limited lift-off height, and low energy conversion efficiency, and the high-altitude power generation equipment is not conducive to maintenance; The generator is placed on the ground, and the cable of the high-altitude kite is used to drive the rotor of the generator to generate electricity, and a winch is installed on the ground to recover the cable when the high-altitude kite descends. However, this method can only generate electric energy during the ascent phase of the kite and requires Energy is consumed to drive the hoist to recover the kite, so the utilization rate of wind energy is low; in addition, foreign researchers have also proposed to use multiple groups of kites connected to the bracket to pull the disc on the ground to rotate, and use the electric hoist to control the retraction and release of the kite cable to realize Aerial kites generate power, but this method has a complex structure and high process costs, and it is not easy to control multiple groups of kites flying together, resulting in entanglement

Embodiment 1

[0042] like figure 1 As shown, in this embodiment, the ground power generation device includes a first operating platform 101, on which a first winch 102 and a first generator 103 connected coaxially are installed, and a movable second operating platform is also included 201 , the second operating platform 201 is towed by a tractor 401 . When the wind direction changes, first the tractor 401 adjusts the position of the second console 201 to drive the second console 201 to rotate around the first console 101, while the first console 101 rotates around its own axis. Make the connection between the two consoles as vertical as possible to the wind direction; when the wind direction (see figure 1When the middle straight arrow) remains unchanged, the second console 201 can be fixed at the current position. In this embodiment, the second transmission device arranged on the second operating platform 201 is a second winch 202 and a second generator 203 connected coaxially. A transmi...

Embodiment 2

[0044] In Embodiment 1, when the connection point between the traction cable 6 and the transmission cable 402 runs close to the second operating platform 201 ( figure 1 Marked by the solid line in the center), first of all, the steering of the high-altitude kite 7 needs to be adjusted through the flight attitude control device (such as figure 1 (indicated by the arc arrow in the middle) to the position marked by the dotted line, and then drive the transmission cable 402 to move in the opposite direction to perform work. During the long journey from the position of the solid line to the position of the dotted line, the transmission cable 402 is not pulled immediately to drive the rotor of the generator to generate power. In this improved embodiment, the transmission cables 402 form a triangular arrangement between the first operating platform 101 and the second operating platform 102 by pulling the pulling cables 6 . The specific operation mode is as described in Embodiment 1....

Embodiment 3

[0046] In Embodiment 1 and Embodiment 2, one side of the transmission cable connecting the first operating platform 101 and the second operating platform 201 is always close to the ground, since the ground power generation devices need to be installed on a large area of ​​ground , has higher requirements on location and environment, and needs to be arranged on complex terrains such as hillsides, canyons and even tops of high-rise buildings in order to get rid of the restrictions of locations. In this improved embodiment, a first sliding device 602 is connected below the junction of the traction cable and the transmission cable through the second traction cable 601 , and the sliding device may be a pulley or other sliding device such as a track. The transmission cable is connected with the first winch 102 and the second winch 202 through the sliding device. like image 3 As shown, when the high-altitude kite moves, the second traction cable 601 drives the first sliding device ...

Description

technical field [0001] The invention belongs to the technical field of wind energy utilization, and relates to a power generating device, in particular to a high-altitude wind power generating device. Background technique [0002] High-altitude wind energy is a new energy that has not been developed and utilized by human beings so far. It is a renewable and clean energy with abundant reserves and wide distribution. Some studies have pointed out that the wind energy stored in the sky is more than 100 times the total energy demand of human society. Among them, the high-altitude wind energy is proportional to the cube of the wind speed. Generally speaking, if the wind speed is doubled, the wind energy will be increased by 8 times. Therefore, the high-altitude wind energy can be several times, ten times, tens of times or even hundreds of times higher than that on the ground. . When the high-altitude location is ideal, the theoretical power generation time of high-altitude wind...
