Description

Technical Field

[0001] The present invention relates to the technical field of new energy equipment, and more specifically, to a solar dual-axis tracker. Background Art

[0002] Solar energy is a kind of energy that has attracted much attention and research in the field of new energy and renewable energy. The main ways to use solar energy are photothermal conversion and photoelectric conversion. These two forms have been widely used and formed large-scale industrialization, generating good economic value.

[0003] Although the use of solar energy has many advantages, there are still some application defects, such as low density, intermittent, and changing direction and intensity of light over time. In particular, the sun rises in the east and sets in the west, which makes it impossible for fixed solar energy conversion modules (such as solar panels) to face the sun all day long, resulting in reduced solar energy conversion efficiency. If you need to improve the conversion efficiency of solar energy, you need to provide a solar automatic tracking system to enable the solar energy conversion module to track the sun in real time.

[0004] In the prior art, typical automatic solar tracking systems mainly include two forms: 1. Single-axis tracking, which tracks the sun only in azimuth and makes seasonal adjustments in altitude; 2. Dual-axis tracking, which tracks the sun's trajectory in both azimuth and altitude. Obviously, the effect of dual-axis tracking is better than that of single-axis tracking.

[0005] However, at present, the solar dual-axis tracking system is mainly used in the photovoltaic field, while the solar thermal field basically adopts single-axis tracking. The main reason is that solar thermal requires the installation of liquid pipelines, and the installation of dual-axis tracking liquid pipelines is much more complicated than that of single-axis tracking, resulting in increased costs and failure rates. In addition, compared with single-axis tracking, dual-axis tracking is difficult to cascade in large quantities, resulting in increased construction costs, which is also the reason why dual-axis tracking is difficult to popularize. Summary of the invention

[0035] Please refer to Figure 1 , Figure 1 The figure is a simplified structural diagram of a solar dual-axis tracker in one embodiment of the present invention.

[0036] The present invention provides a solar dual-axis tracker, which establishes a Cartesian coordinate system in a plane, wherein the horizontal axis and the vertical axis in the horizontal plane are the X-axis and the Y-axis, and the axis in the vertical height direction is the Z-axis. The solar dual-axis tracker provided by the present invention has a rotational freedom of rotation about the X-axis and about the Y-axis.

[0037] In the present invention, the solar dual-axis tracker includes the following components:

[0038] 1. A heat pipe battery 1 for converting solar radiation into heat energy and electrical energy.

[0039] The energy-concentrating heat pipe battery 1 has two functions, one is to convert solar radiation into thermal energy, and the other is to convert solar radiation into electrical energy.

[0040] As for converting solar radiation into heat energy, the present invention realizes this function by providing a transparent tube and related auxiliary accessories.

[0041] Specifically, the energy-concentrating heat pipe battery 1 includes a transparent tube, which is preferably a glass tube, and its cross-section is preferably circular. The transparent tube is preferably a straight tube, and end caps are provided at both ends of the transparent tube. The end caps are used to close the two ends of the transparent tube, so that the transparent tube forms a closed tube structure that allows the heat exchange medium to flow.

[0042] The purpose of setting the transparent tube in the present invention is to enable the heat exchange medium to circulate in the transparent tube, thereby absorbing solar radiation to increase temperature and then providing thermal energy (hot water). Therefore, in the actual working process, the heat exchange medium needs to flow. For this purpose, the present invention provides a heat exchange medium circulation system connected to the transparent tube. The heat exchange medium circulation system includes a heat storage tank, which is connected to the transparent tube through a pipeline. A water pump is arranged on the pipeline, and the water pump pumps the heat exchange medium to circulate in the circulation system.

[0043] As for converting solar radiation into electrical energy, the present invention realizes this function by setting up solar cells. Specifically, the present invention encapsulates solar cells (monocrystalline silicon solar cells or polycrystalline silicon solar cells) in a transparent tube, and a power conductor (used to output the electrical energy converted by the solar cell) is led out from the solar cell, and the power conductor is sealed and extends outward through the end cover (a butt-joint pipe is provided on the end cover for outputting the heat exchange medium, a hole structure is provided on the end cover, a weather-resistant rubber plug is provided in the hole structure, and the power conductor extends outward through the weather-resistant rubber plug, and the above-mentioned butt-joint pipe can be integrally formed on the end cover, and a sealant can be provided between the weather-resistant rubber plug and the end cover and the power conductor to improve the sealing performance).

[0044] In the above structural design, a heat exchange medium flows through the transparent tube, and the heat exchange medium absorbs solar radiation, heats up, and outputs heat energy to the outside; the solar cell converts the solar radiation into electrical energy and outputs it to the outside.

[0045] It should be noted that: the present invention encapsulates the solar cell into a transparent tube, and a transparent protective film is provided on the outside of the solar cell to isolate the solar cell from the heat exchange medium.

[0046] In the above structural design, solar cells are arranged in the transparent tube to form a concentrated heat pipe cell 1 (a component) capable of converting solar radiation into heat energy and electrical energy.

[0047] In the prior art, solar heat pipes or solar panels are all installed in a fixed manner, and only a few solar power plants use single-axis tracking solar panels, which results in a problem of reduced solar radiation utilization.

[0048] In order to solve the above problems, the present invention proposes two structural optimization designs: 1. Combining photothermal and photoelectric to form a concentrated heat pipe battery assembly, such as the above structure; 2. Designing a dual-axis tracking structure to increase the degree of freedom of the concentrated heat pipe battery 1, so that the concentrated heat pipe battery 1 can face the sun all day long.

[0049] In the above-mentioned second optimized design, the present invention adopts the following structure: in the height direction (i.e., in the vertical direction when in use), a concentrator 2 is arranged below the concentrating heat pipe battery 1, and the concentrator 2 is used to reflect solar radiation onto the concentrating heat pipe battery 1.

[0050] The present invention can also provide a condenser 2, which is an arc-shaped reflective structure as a whole. By setting the condenser 2, the solar radiation in a large area (the projection area of ​​the condenser 2) can be reflected to a point (or an axis), and the point is set as the focusing point. The present invention can set the energy-concentrating heat pipe battery 1 at the focusing point, thereby improving the absorption rate of the energy-concentrating heat pipe battery 1 to solar radiation, and then increasing the output efficiency of thermal energy.

[0051] Furthermore, the concentrator 2 is an arc-shaped plate structure, and the upper side surface of the concentrator 2 is a reflective surface that can reflect light. The reflective surface has a focusing axis, and the focusing axis is a focusing focal line formed by the reflection of the reflective surface. The focusing axis runs through the energy-concentrating heat tube battery 1. Through structural design, when the concentrator 2 rotates around the focusing axis (or around the energy-concentrating heat tube battery 1), the solar radiation reflected by the concentrator 2 can be reflected into the energy-concentrating heat tube battery 1.

[0052] In the height direction (i.e. in the vertical direction when in use), an auxiliary beam 3 is arranged below the condenser 2. The auxiliary beam 3 is a long axis structure. The condenser 2 is connected to the auxiliary beam 3. The connection structure enables the condenser 2 and the auxiliary beam 3 to be linked. When the auxiliary beam 3 rotates, the condenser 2 can rotate around the auxiliary beam 3 with the auxiliary beam 3 as the rotation center.

[0053] In one embodiment of the present invention, a support arm extending along an axial direction perpendicular to the auxiliary beam 3 is provided on the auxiliary beam 3, and the support arm is a multi-section upward curved support arm. The support arms are grouped into two, and the two support arms in the same group are symmetrically arranged on both sides of the auxiliary beam 3. A plurality of groups of support arms are arranged at intervals along the axial direction of the auxiliary beam 3, and the support arms are used to install and fix the condenser 2 arranged above the auxiliary beam 3, thereby improving the reliability of the condenser 2 arranged on the auxiliary beam 3.

[0054] The above structural design can realize the rotation of the concentrator 2 in one dimension (X axis). Furthermore, the present invention also provides an auxiliary beam mounting frame 4 to realize the rotation of the concentrator 2 and the energy-concentrating heat pipe battery 1 in another dimension (Y axis). The auxiliary beam 3 is rotatably arranged on the auxiliary beam mounting frame 4, the auxiliary beam 3 can rotate around its axis and the concentrator 2 can be linked with the auxiliary beam 3. In the height direction, the main beam 5 is arranged below the auxiliary beam mounting frame 4, the main beam 5 and the auxiliary beam 3 are arranged horizontally and the main beam 5 is perpendicular to the auxiliary beam 3. The present invention also provides a main beam mounting frame 6, through which the main beam 5 is installed and the rotation of the main beam 5 is realized. The main beam 5 is rotatably arranged on the main beam 5 installation machine, the main beam 5 can rotate around its axis, and the auxiliary beam mounting frame 4 is arranged on the main beam 5 and can be linked with the main beam 5.

[0055] The present invention is further provided with a first driving device 7 , which is dynamically connected to the main beam 5 .

[0056] The present invention is also provided with a second driving device, which is dynamically connected to the auxiliary beam 3 .

[0057] The auxiliary beam mounting frame 4 has the function of mounting the auxiliary beam 3. The auxiliary beam 3 is also provided with a concentrator 2 and a heat pipe battery 1. Therefore, the auxiliary beam mounting frame 4 has to bear a relatively large gravity. In order to ensure that the auxiliary beam mounting frame 4 can stably and reliably mount the auxiliary beam 3, the concentrator 2 and the heat pipe battery 1, the present invention performs the following structural design on the auxiliary beam mounting frame 4: the auxiliary beam mounting frame 4 includes an inclined support, which is obliquely arranged on the side walls on both sides of the axis direction of the main beam 5. The inclined supports are grouped in two, and the two inclined supports of the same group are symmetrically arranged on both sides of the main beam 5. Multiple groups of inclined supports are arranged at intervals along the axis direction of the main beam 5. A main frame is arranged at the top of the inclined support, and a first bearing seat is arranged on the main frame. The auxiliary beam 3 is arranged on the main frame through the first bearing seat.

[0058] Furthermore, the auxiliary beam mounting frame 4 also includes a vertically arranged connecting rod, which is vertically arranged, nested on the auxiliary beam 3 and linked with the auxiliary beam 3, and the energy-concentrating heat pipe battery 1 is arranged at the top of the connecting rod. By arranging the connecting rod, the energy-concentrating heat pipe battery 1 can rotate with the connecting rod, so that the battery sheet on the energy-concentrating heat pipe battery 1 can rotate toward the sun.

[0059] Furthermore, a linkage rod is hinged at the bottom end of the connecting rod, and the second driving device is dynamically connected to the linkage rod and drives the auxiliary beam 3 to move through the linkage rod.

[0060] In the present invention, the main beam mounting frame 6 includes a vertically arranged side bracket, which is a tripod structure. There are two side brackets, which are arranged on both sides of the main beam 5. A second bearing seat is arranged on the side bracket, and the main beam 5 is installed on the side bracket through the second bearing seat. A base frame is also arranged between the two side brackets.

[0061] Furthermore, the first driving device 7 is a rotary motor; the second driving device is a rotary motor.

[0062] In the present invention, components with weighing or force transmission functions are all made of metal profiles (which may be stainless steel profiles or aluminum alloy profiles), such as linkage rods, diagonal supports, side brackets, connecting rods, etc.

[0063] As can be seen from the above, the present invention provides a solar dual-axis tracker, which includes a concentrating heat tube battery 1 for converting solar radiation into thermal energy and electrical energy.

The present invention adds one-dimensional axial tracking on the basis of the original single-axis tracking system, optimizes the tracking structure and transmission mode, so that the condenser 2 can move on two rotation axes, and can simultaneously track the changes in the azimuth and altitude angles of the sun, thereby ensuring the best focusing effect to improve the heating efficiency.

[0064] The general structure of the present invention is: it includes a main beam 5, four auxiliary beams 3, an auxiliary beam mounting frame 4, two rotary motors, four concentrators 2 and four energy-concentrating heat pipe batteries 1. The main beam 5 is connected to the power of a rotary motor, which is responsible for completing the one-dimensional rotation of the system.
