Description

Technical Field

[0001] This utility model belongs to the field of solar cell application technology, specifically relating to a suspended solar cell. Background Technology

[0002] On stratospheric airships, solar energy is one of the important sources of energy supply. Existing stratospheric airships have solar panels installed on their tops for solar power generation. In practical applications, the airship's attitude generally remains unchanged, so the solar panels on its top are also stationary (excluding changes in the airship's position during flight). However, the sun's position and angle of illumination vary in different regions of the Earth, and these changes continuously over time. As a result, the luminous flux of the solar panels is not stable, leading to low efficiency in the utilization of solar energy. Utility Model Content

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Figure 1 This is a schematic diagram of the overall structure of the suspended solar cell provided in this embodiment of the utility model.

[0027] like Figure 1As shown, this utility model provides a suspended solar cell, including a solar panel assembly 1 and a suspension assembly 2. The solar panel assembly 1 includes a solar panel 11 and at least two first suspension parts 12 disposed on the solar panel. The suspension assembly 2 includes a connecting part 21 and a second suspension part 22. The connecting part 21 of the suspension assembly 2 is connected to an external suspension facility. The second suspension part 22 and the first suspension part 12 are connected by a suspension rope 3, thereby enabling the solar panel 11 to be suspended in the air. An adjustment mechanism 4 is provided on the suspension rope 3. The adjustment mechanism 4 is used to adjust the length of the suspension rope 3 between the first suspension part 12 and the second suspension part 22. By adjusting the length of at least two suspension ropes 3, the relative angle between the solar panel 11 and the suspension assembly 2 can be adjusted, that is, the angle between the solar panel 11 and the horizontal plane can be adjusted, so that the solar panel can face the sun as directly as possible, thereby increasing the light energy that the solar panel can receive, and thus improving the solar energy collection efficiency and the final power generation efficiency.

[0028] The external suspension system is typically an airship, especially a stratospheric airship. The solar cells provided by this invention are suspended at the bottom of the airship to provide power to various electrical components within it. Furthermore, the solar cells provided by this invention can also be applied to other facilities, all of which can effectively collect solar energy and have high power generation efficiency. The application areas of this invention will not be elaborated here. The suspension rope 3 can be an existing sling such as a steel cable, steel wire rope, or synthetic fiber, as long as it meets the strength requirements for suspending the solar panel 11. Further details are omitted here.

[0029] In addition, the solar panel 11 can be a solar cell array composed of multiple solar cells, each solar cell measuring 2 meters x 1 meter, and each solar cell array consisting of 10 solar cells. The solar cells can be monocrystalline silicon solar cells, which have high photoelectric conversion efficiency and good radiation resistance, and can adapt to the special environment of the stratosphere.

[0030] In one preferred embodiment, at least three first lifting parts 12 are provided on the solar panel 11, and the lines connecting adjacent first lifting parts 12 intersect each other. By providing at least three first lifting parts 12, and these three first lifting parts 12 can define a plane, when adjusting the orientation and angle of the solar panel 11 by adjusting the length of the lifting rope 3, the solar panel 11 can be driven to rotate about the line connecting every two first lifting parts 12 as the rotation axis. The solar panel 11 has more adjustment methods and can achieve more pose states and orientations, further improving the solar energy collection efficiency and power generation efficiency of the solar panel 11.

[0031] Alternatively, when only two first hoisting parts 12 are provided on the solar panel 11, the connecting part 21 of the hoisting assembly 2 can be rotatably connected to the external suspension facility (the axis of rotation is perpendicular to the horizontal plane). In this way, when the angle of the solar panel 11 is adjusted by changing the length of the hoisting rope 3, the connecting part 21 drives the entire hoisted solar cell to rotate, which can also enable the solar panel 11 to have more positional states and orientations, thereby improving power generation efficiency.

[0032] like Figure 1 As shown, in one preferred embodiment, the number of second lifting parts 22 on the lifting assembly 2 is the same as the number of first lifting parts 12 on the solar panel assembly 1. Each second lifting part 22 corresponds one-to-one with a first lifting part 12. A lifting rope 3 is provided between the corresponding second lifting part 22 and the first lifting part 12. An adjustment mechanism 4 is provided on each lifting rope 3. By providing multiple second lifting parts 22 corresponding to the first lifting parts 12, and providing a lifting rope 3 and an adjustment mechanism 4 between each group of lifting parts, it is easier for the adjustment mechanism 4 to adjust the length of each lifting rope 3 individually.

[0033] Furthermore, the shape formed by the lines connecting the second hoisting section 22 can be set to be the same as the shape formed by the first hoisting section 12. Figure 1 In the illustrated embodiment, there are four second lifting sections 22, roughly forming a square, and the first lifting sections 12 also have four, also forming a square. This makes the pulling force of the lifting ropes 3 on the lifting assembly 2 and the solar panel assembly 1 more uniform, reducing stress concentration and improving the stability and safety of the lifting. Alternatively, the connecting section 21 can be located at the geometric center of the shape formed by the second lifting sections 22, so that the resultant external force of the second lifting section 22 (and the entire solar panel) on the connecting section 21 is vertically downward, making the force on the connecting section 21 more uniform in all directions, which is beneficial to improving overall stability. In addition, besides... Figure 1 In addition to the square shown, the first hoisting part 12 and the second hoisting part 22 can also form other shapes, which will not be elaborated here.

[0034] Figure 2 This is a schematic diagram of the structure of the adjustment mechanism for hoisting solar cells provided in this embodiment of the utility model.

[0035] like Figure 2 As shown, in one preferred embodiment, the adjustment mechanism 4 includes a winch, which is located at the first hoisting section 12 or the second hoisting section 22. The winch can change the length of the hoisting rope 3 by winding or releasing the rope 3.

[0036] exist Figure 2In the embodiment shown, the winch includes a motor 41 and a spool 42. A baffle 43 is provided on the spool 42. One end of the suspension rope 3 is fixed between the baffles 43 on the spool 42. By driving the spool 42 to rotate through the motor 41, the suspension rope 3 can be wound around the spool 42, or the suspension rope 3 wound on the spool 42 can be released, thereby changing the length of the suspension rope 3.

[0037] Furthermore, the winch also includes a mounting base 49 for mounting the winch on the solar panel assembly 1. The motor 41 and the spool 42 are both mounted on the mounting base 49. An electrical box 48 is also provided on one side of the motor 41, and the electrical box 48 is electrically connected to the motor 41. A first gear 45 is provided at the output end of the motor 41, and a third gear 47 is connected to one end of the spool 42. The first gear 45 and the third gear 47 are driven by a second gear 46, and all three gears are housed in a transmission box 44. The second gear 46 facilitates setting the transmission ratio between the motor 41 and the spool 42. The electrical box 48 controls the start / stop and speed of the motor 41, making it easier to adjust the length of the suspension rope 3. In some other embodiments, the adjustment mechanism 4 can also use some existing equipment, as long as it can adjust the length of the suspension rope 3.

[0038] Figure 3 This is a schematic diagram of the structure of the first truss for suspending solar cells provided in an embodiment of this utility model.

[0039] like Figure 1 and Figure 3 As shown, in one preferred embodiment, the solar panel assembly 1 further includes a first truss 13, which is disposed on the side of the solar panel 11 away from the hoisting assembly 2. By providing the first truss 13 on the solar panel 11, the overall strength of the solar panel 11 can be effectively improved, so that the solar panel 11 can maintain good stability when subjected to strong airflow interference.

[0040] In addition, such as Figure 3 As shown, the first truss 13 may include a first structure 131, which is generally triangular prism in shape. After being connected into a triangle by rigid rods, several of these triangular structures are connected vertically at their three corners. It also includes a first structural rod 132, used to connect multiple triangular prism-shaped first structures 131 into a plate-like structure. The resulting first truss 13 has good structural strength and can provide stable and robust support for the solar panel 11. In summary, the design of the first truss 13 should balance strength and weight. The lower the weight of the first truss 13, the smaller the load that the suspension rope 3 and the connecting part 21 need to bear. The specific shape of the first truss 13 can be adaptively adjusted according to actual conditions, which will not be elaborated here.

[0041] Furthermore, such as Figure 1 and Figure 3 As shown, in one preferred embodiment, the first truss 13 has a mounting portion 1311 protruding horizontally from the solar panel 11. The mounting portion 1311 is used for connecting and installing the first hoisting portion 12 and the adjusting mechanism 4. Figure 2 and Figure 3 In the illustrated embodiment, the mounting base 49 of the adjustment mechanism 4 is mounted on the mounting portion 1311 of the first truss 13, fixing both the first hoisting portion 12 and the adjustment mechanism 4 to the first truss 13, making the hoisting of the solar cells more stable and reliable. Meanwhile, as... Figure 1 As shown, by setting all the first hoisting parts 12 on the mounting part 1311, the area enclosed by the first hoisting parts 12 is larger than the area of ​​the solar panel 11. That is, the solar panel 11 is located inside the first hoisting parts 12. The hoisting rope 3, the first hoisting parts 12 and the first truss 13 form a pocket-shaped structure. The solar panel 11 is located inside the pocket-shaped structure. Except for unavoidable environmental forces (wind force and gravity, etc.) and the supporting force of the first truss 13, the solar panel 11 is not subjected to additional external forces. This can play a good protective role for the structure of the solar panel 11, improve the structural stability of the solar panel 11 and the overall service life.

[0042] Figure 4 This is a schematic diagram of the structure of the second truss for suspending solar cells provided in an embodiment of this utility model.

[0043] like Figure 4 As shown, the hoisting assembly 2 includes a second truss 23, a second hoisting part 22 and a connecting part 21, all of which are disposed on the second truss 23. The connecting part 21 is located at the geometric center of the second truss 23. By setting the second truss 23, the overall weight of the hoisted solar cell of this utility model can be reduced as much as possible while ensuring the overall hoisting stability.

[0044] The second truss 23 can be configured as a cross shape, comprising a first frame 231 and a second frame 232. Two triangular prism-shaped frames are fixedly connected to form the second truss 23. Four second lifting parts 22 are provided on the second truss 23, and the four second lifting parts 22 are respectively located at the four ends of the second truss 23. Correspondingly, the solar panel 11 (or the first truss 13) is rectangular, and four first lifting parts 12 are provided, respectively located at the four corners of the solar panel 11 (or the first truss 13), which can improve the overall connection stability. Furthermore, configuring the second truss 23 as a cross shape can minimize the shading of sunlight received by the solar panel 11 by the second truss 23, which is beneficial to improving power generation efficiency.

[0045] The first truss 13 and the second truss 23 are preferably made of carbon fiber, which has good structural strength and low overall weight, thus reducing the load on the hoisting and improving the stability of the hoisting.

[0046] like Figure 4 As shown, in one preferred embodiment, a control system is also included. The control system includes a data acquisition module and a calculation output module. The data acquisition module includes a GPS component 8, an inertial component 7, and a geomagnetic component 5, which are used to collect position and time parameters, motion parameters, and geomagnetic navigation parameters, respectively. The calculation output module includes a main control system 5, which controls the operation of the adjustment mechanism 4 according to the parameters of the data acquisition module. The data acquisition module and the calculation output module are preferably set on the second truss 23, which can reduce the workload of the suspension rope 3. By setting up a control system, the automatic control of the adjustment mechanism 4 can be realized, improving the convenience of application.

[0047] The GPS component 8 can collect real-time information on the altitude, latitude, longitude, and local time of the stratospheric airship with meter-level accuracy, providing accurate data for determining the airship's geographical location. The inertial component 7 includes a three-axis accelerometer, a three-axis gyroscope, and a three-axis magnetometer, which can accurately measure motion parameters such as three-axis velocity, angular velocity, acceleration, and angular acceleration with high measurement accuracy and fast response, enabling real-time reflection of the truss's attitude and motion state in the air. The magnetic compass is used to measure the geomagnetic heading, providing a reference for heading control, with a measurement accuracy of ±0.5 degrees. The main control system, as the control center of the entire automatic tracking system, uses a high-performance embedded computer with powerful data processing capabilities and real-time performance. It can collect data from the data acquisition module and accurately calculate the current position of the sun based on the built-in formulas for calculating the solar altitude angle and azimuth angle. Based on the calculated solar altitude angle and azimuth angle, corresponding control signals are generated and sent to the electrical box 48 of the adjustment mechanism to control the motor 41 to operate and retract the hoisting rope 3, thereby adjusting the altitude angle and azimuth angle of the solar array. In this way, the normal of the solar array is always kept parallel to the sunlight, achieving direct sunlight on the array surface and maximizing the light absorption efficiency of solar energy. This provides the stratospheric airship with an efficient and stable energy supply, ensuring its long-term stable flight and mission execution in the stratosphere.

[0048] In this embodiment, the control system integrates multiple advanced sensors and an intelligent control computer, achieving automated solar tracking. Without manual intervention, the system can collect various status information of the airship in real time, accurately calculate the sun's position, and quickly adjust the angle accordingly. This not only improves the system's intelligence level but also enhances its operational stability and reliability, ensuring that the solar array can accurately track the sun under various complex flight conditions and environmental circumstances, fully leveraging its energy harvesting efficiency. This provides strong technical support for the efficient operation and widespread application of stratospheric airships.

[0049] Figure 5 This is a side view of the truss provided in an embodiment of the present invention.

[0050] like Figure 5 As shown, in one preferred embodiment, the second truss 23 is suspended below the stratospheric airship. Its single-side length can be selected in the range of 5-50 meters according to the size of the airship and energy requirements. In this embodiment, the single-side length of the second truss 23 is 10 meters. The truss is made of high-strength carbon fiber material, and its cross-section is an equilateral triangle structure with a vertex angle of 60 degrees. This structural design not only ensures that the truss itself has good strength and rigidity and can withstand the complex environmental conditions of the stratosphere and the weight of the solar cell array, but also provides sufficient space and stable support for the installation and angle adjustment of the first truss 13 below and the solar cell array. The first truss 13 also has a side length of 10 meters and is suspended below the second truss 23 and connected to the second truss by four thin steel cables 3.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solution of this utility model do not depart from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered by the claims of this utility model.
