DETAILED DESCRIPTION

[0020] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative effort belong to the scope of protection of the present application.

[0021] As shown in Figure 1 and Figure 4 , the present application provides an umbrella opening device suitable for high-altitude wind power generation, which comprises a split power supply 3 and a plurality of ribs 1. The plurality of ribs 1 are distributed in a radial manner and uniformly arranged on the umbrella surface 101 of the umbrella body 10. A first electromagnetic coil 11 is arranged in each rib 1. The split power supply 3 is arranged at the top end of the rib 1 and electrically connected with the first electromagnetic coil 11. The opening and closing of the umbrella body 10 are controlled by controlling the polarity of the first electromagnetic coil 11.

[0022] In the present embodiment, the rib 1 and the split power supply 3 are arranged on the umbrella body 10, and the first electromagnetic coil 11 is arranged in each rib 1. The split power supply 3 is electrically connected with the first electromagnetic coil 11. In this way, the polarity of the first electromagnetic coil 11 can be controlled by controlling the current direction of the first electromagnetic coil 11, so that the opening and closing of the umbrella body 10 can be effectively and actively controlled. Further, the magnetic field size can be controlled by changing the output power of the split power supply 3, so that the mutual magnetic interaction force between the ribs 1 can be indirectly controlled, and thus the speed and degree of opening and closing of the umbrella body 10 can be adjusted.

[0023] That is to say, a complete circuit loop can be accommodated in each rib 1, that is, a closed loop of the circuit can be realized in each rib 1.

[0024] In an embodiment of the present application, the above-mentioned umbrella opening device further comprises a plurality of edges 2. Each edge 2 is connected between the bottom ends of two adjacent ribs 1. A second electromagnetic coil 21 is arranged in each edge 2. The split power supply 3 is electrically connected with the second electromagnetic coil 21. The first electromagnetic coil 11 and the second electromagnetic coil 21 are connected in series.

[0025] In the present embodiment, the rib 1, the edge 2 and the split power supply 3 are arranged on the umbrella body 10 by introducing the edge. The first electromagnetic coil 11 is arranged in each rib 1, and the second electromagnetic coil 21 is arranged in each edge 2. The split power supply 3 is electrically connected with the second electromagnetic coil 21. The first electromagnetic coil 11 and the second electromagnetic coil 21 are connected in series. In this way, the polarity of the first electromagnetic coil 11 and the second electromagnetic coil 21 can be controlled by controlling the current direction of the first electromagnetic coil 11 and the second electromagnetic coil 21, so that the opening and closing of the umbrella body 10 can be further effectively and actively controlled.

[0026] Furthermore, the magnitude of the magnetic field can be controlled by changing the output power of the split power supply 3, thereby indirectly controlling the mutual magnetic force between the umbrella ribs 1 and the edging 2, thus adjusting the speed and extent of the opening and closing of the umbrella body 10.

[0027] Furthermore, by combining wind speed, wind force, and wind direction data, this method can achieve precise control over the opening and closing of the umbrella 10. For example, when the wind speed is high, the split power supply 3 can be turned off, allowing wind to enter the umbrella 10 to achieve natural opening; when the wind speed is low, the split power supply 3 can be turned off, allowing the umbrella 10 to close naturally; when the wind speed is high, the current can be reduced to prevent the umbrella 10 from closing completely, achieving partial wind capture; when the wind speed is low, the current can be increased to prevent the umbrella 10 from closing completely, achieving partial wind capture.

[0028] In some embodiments, the umbrella body 10 includes a power umbrella and a balancing umbrella, which are not specifically limited here.

[0029] In some implementations, to increase the magnetic force generated by the electromagnetic coil, the number of turns of the electromagnetic coil can be increased, or an iron core can be inserted in the middle of the electromagnetic coil, which will not be elaborated here.

[0030] like Figure 2 As shown, in one embodiment of the present invention, the split power supply 3 has a ring structure, and the cable for high-altitude wind power generation passes through the through hole 102 formed by the split power supply 3.

[0031] In this embodiment, by setting the split power supply 3 as a ring structure, it can be easily installed at the top of the umbrella rib 1, and the position where the cable passes through can be easily avoided.

[0032] In one embodiment of the present invention, the split power supply 3 includes multiple unit modules 31, each unit module 31 including a sub-power supply 311 and a control circuit 312. The sub-power supply 311, the control circuit 312, the first electromagnetic coil 11 and the second electromagnetic coil 21 are electrically connected. The control circuit 312 is used to control the current direction of the first electromagnetic coil 11 and the second electromagnetic coil 21, so as to control the polarity of the first electromagnetic coil 11 and the second electromagnetic coil 21.

[0033] In this embodiment, by providing a sub-power supply 311 and a control circuit 312 in each unit module 31, the control circuit 312 can be used to control the current direction of the first electromagnetic coil 11 and the second electromagnetic coil 21, thereby controlling the polarity of the first electromagnetic coil 11 and the second electromagnetic coil 21.

[0034] In some implementations, the sub-power source 311 can be a current source or a voltage source, such as an energy storage battery or a flexible photovoltaic panel, without being specifically limited here.

[0035] In one embodiment of the present invention, an insulating layer 32 is provided between two adjacent unit modules 31. This arrangement helps to ensure the operational safety between unit modules 31 and prevents short circuits from occurring.

[0036] like Figure 3 As shown, in one embodiment of the present invention, the control circuit 312 includes a first semiconductor switch 312a, a second semiconductor switch 312b, a third semiconductor switch 312c, and a fourth semiconductor switch 312d. The first ends of the first semiconductor switch 312a and the second semiconductor switch 312b are connected to the positive terminal of the sub-power supply 311. The second ends of the first semiconductor switch 312a and the first ends of the third semiconductor switch 312c are connected to the first electromagnetic coil 11. The second ends of the second semiconductor switch 312b and the first ends of the fourth semiconductor switch 312d are connected to the second electromagnetic coil 21. The second ends of the third semiconductor switch 312c and the fourth semiconductor switch 312d are connected to the negative terminal of the sub-power supply 311.

[0037] In this embodiment, by configuring the control circuit 312 with a first semiconductor switch 312a, a second semiconductor switch 312b, a third semiconductor switch 312c, and a fourth semiconductor switch 312d, the on / off states of the first semiconductor switch 312a, the second semiconductor switch 312b, the third semiconductor switch 312c, and the fourth semiconductor switch 312d can be controlled to control the current direction of the first electromagnetic coil 11 and the second electromagnetic coil 21, thereby controlling the polarity of the first electromagnetic coil 11 and the second electromagnetic coil 21.

[0038] For example, when the first semiconductor switch 312a and the fourth semiconductor switch 312d are open, while the second semiconductor switch 312b and the third semiconductor switch 312c are closed, the direction of the current in the electromagnetic coil is... Figure 3 From top to bottom; when the first semiconductor switch 312a and the fourth semiconductor switch 312d are closed, and the second semiconductor switch 312b and the third semiconductor switch 312c are open, the direction of the current in the electromagnetic coil is... Figure 3 The direction is from bottom to top. Therefore, it can be seen that by controlling the on / off state of the first semiconductor switch 312a, the second semiconductor switch 312b, the third semiconductor switch 312c, and the fourth semiconductor switch 312d, the direction of the current in the first electromagnetic coil 11 and the second electromagnetic coil 21 can be controlled.

[0039] In some implementations, the semiconductor switch can be any of IGBT, FET, or BJT, and the type of semiconductor switch is not specifically limited here.

[0040] Understandable, Figure 3The electromagnetic coils shown are the collection of the first electromagnetic coil 11 and the second electromagnetic coil 21, which represent the load.

[0041] In an embodiment of the present application, each unit module 31 further comprises a variable resistor 313, which is used to change the current size of the first electromagnetic coil 11 and the second electromagnetic coil 21. In this way, the current size of the first electromagnetic coil 11 and the second electromagnetic coil 21 is changed by changing the resistance of the variable resistor 313, so as to achieve an incomplete opening or an incomplete closing of the umbrella.

[0042] When the sub-power supply 311 is a voltage source, the variable resistor 313 and the electromagnetic coil can be connected in series; when the sub-power supply 311 is a current source, the variable resistor 313 and the electromagnetic coil can be connected in parallel. Among them, Figure 3 In the circuit shown, the sub-power supply 311 is a current source.

[0043] Please continue to refer to Figure 4 In an embodiment of the present application, a straight wire 12 is arranged in each rib 1, a connecting terminal 22 is arranged at the connection between the rib 1 and the edge 2, two adjacent ribs 1 and the edge 2 connected with the two ribs 1 form an independent unit, and two adjacent independent units share one rib 1. In each independent unit, the first electromagnetic coil 11 and the straight wire 12 are electrically connected with the second electromagnetic coil 21 through the connecting terminals 22 at both ends of the edge 2.

[0044] That is to say, a first electromagnetic coil 11 and a straight wire 12 are arranged in each rib 1, and the rib 1 and the edge 2 play the role of protecting and insulating the electromagnetic coil and the straight wire 12.

[0045] It can be understood that by respectively controlling the on-off of the semiconductor switch and the resistance of the variable resistor 313 in each unit module 31, when the magnetic poles and magnetic forces of each electromagnetic coil are in a completely synchronized state, the entire umbrella body 10 can present a relatively standard circular umbrella shape; when the magnetic poles and magnetic forces of each coil are in different states, by changing the direction of the magnetic pole and the size of the magnetic force on each electromagnetic coil, the shape of the umbrella body 10 can be changed to a certain extent (i.e. irregular shape), so as to increase or decrease the wind catching amount, thereby realizing the safety guarantee of high-altitude wind power generation.

[0046] In addition, the embodiment of the present application further provides a working method of an umbrella opening device suitable for high-altitude wind power generation, which is applied to the umbrella opening device mentioned in the above embodiment and comprises the following steps: Full opening of the umbrella: by controlling the control circuit 312 of each unit module 31, the polarity direction of the first electromagnetic coil 11 in the adjacent rib 1 is the same, and the polarity direction of the second electromagnetic coil 21 in the adjacent edge 2 is opposite, so as to realize active opening of the umbrella by using the repulsive magnetic force generated. Full closing of the umbrella: by controlling the control circuit 312 of each unit module 31, the polarity direction of the first electromagnetic coil 11 in the adjacent rib 1 is opposite, and the polarity direction of the second electromagnetic coil 21 in the adjacent edge 2 is the same, so as to realize active closing of the umbrella by using the mutual magnetic force generated.

[0047] It can be understood that the working method of the opening umbrella device suitable for high-altitude wind power generation provided by the embodiment of the present application and the opening umbrella device suitable for high-altitude wind power generation provided by the above-mentioned embodiment are based on the same inventive concept, and therefore have the same beneficial effects. Therefore, the beneficial effects of the working method of the opening umbrella device suitable for high-altitude wind power generation will not be described here.

[0048] In an embodiment of the present application, the above-mentioned method further comprises: During the opening or closing of the umbrella, the current of the first electromagnetic coil 11 and the second electromagnetic coil 21 is changed by changing the resistance value of the variable resistor 313, so as to realize incomplete opening or incomplete closing of the umbrella.

[0049] In addition, the embodiment of the present application further provides an aerial assembly suitable for a high-altitude wind power generation system, which comprises a cable (not shown in the figure) and an umbrella body 10 and a floating device (not shown in the figure) arranged on the cable, and the umbrella body 10 is provided with the opening umbrella device mentioned in any one of the above-mentioned embodiments.
