Description

Technical Field

[0001] This invention relates to the field of new energy technology, specifically to a self-tracking solar thermal collector structure based on the characteristics of strong solar radiation on plateaus. Background Technology

[0002] The strong solar radiation characteristic of plateau regions refers to the unique solar radiation conditions in plateau areas, which are more intense than those in low-altitude plains at the same latitude. Solar thermal collectors generally use collector tubes, with a vacuum between the tubes and a heat exchange medium inside. One end of the collector tube is inserted into the water tank of a solar water heater. When sunlight shines on the collector, it can pass through the outer glass tube and transfer heat to the heat exchange medium to achieve heating. The installation direction of the solar panel directly affects the utilization rate of solar energy.

[0003] However, current solar panels are typically installed in a fixed orientation based on local sunlight conditions, making it inconvenient to adjust the angle according to sunlight intensity. Furthermore, the angle of sunlight varies throughout the day, and the energy radiated to the Earth's surface also changes with this angle. The intensity of sunlight varies significantly at different times of day. Moreover, simply directing sunlight onto the solar panels for heat collection results in low utilization of sunlight due to the limited surface area, leading to instability and uneven distribution of solar thermal energy. Therefore, we need to propose a self-tracking solar thermal collection structure based on the characteristics of strong sunlight in high-altitude areas. Summary of the Invention

[0004] The purpose of this invention is to provide a self-tracking solar thermal collector structure based on the characteristics of strong solar radiation on plateaus. This structure can adjust the angle of light reception of the solar thermal collector according to usage requirements, so that the collector plate is always at the optimal angle of light reception to adapt to the sunlight reception at different times of the day, ensuring the stability of solar thermal energy and further improving the utilization rate of sunlight, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides: a self-tracking solar thermal collector structure based on the characteristics of strong solar radiation in high-altitude areas, comprising a self-tracking solar thermal collector panel, a heat collection tube, a mounting base, and a mounting frame; the self-tracking solar thermal collector panel has a reflective heat collection plate inside to cooperate with the heat collection tube, and a light tracker and a fault alarm are respectively provided at the ends of the self-tracking solar thermal collector panel; the top of the mounting base is connected to a movably mounted mounting frame via a flip motor, one end of the top of the mounting frame is movably connected to an assembly support plate at the bottom of the self-tracking solar thermal collector panel, and the surface of the mounting frame is provided with an adjustment component for controlling the angle of the self-tracking solar thermal collector panel; a flip motor for driving and flipping the position of the mounting frame is mounted on the surface of the mounting base.

[0006] Preferably, the adjustment assembly includes: a protective frame mounted on the surface of the mounting bracket, and an adjustment screw rotatably mounted inside the protective frame; wherein, the surface of the adjustment screw is connected to an adjustment seat, both sides of the adjustment seat are connected to anti-detachment linkages, and one end of the mounting bracket is connected to an assembly shaft that cooperates with the assembly support plate.

[0007] Preferably, an adjusting motor is mounted on the surface of the protective frame, the output end of the adjusting motor is driven and connected to the end of the adjusting screw, and a connecting support rod is rotatably connected to the surface of the anti-detachment linkage.

[0008] Preferably, the other end of the connecting rod is connected to an installation sleeve, and an installation link is installed on one side of the bottom of the self-tracking solar collector, with the inner wall of the installation sleeve movably connected to the surface of the installation link.

[0009] Preferably, a control module housing is mounted on the surface of the mounting base, a brake is mounted on one side of the inside of the control module housing, and a connecting shaft for connecting to the mounting bracket is provided on the surface of the mounting base.

[0010] Preferably, the brake is connected to the end of the connecting shaft, the central axis of the connecting shaft is configured to cooperate with the drive shaft of the flip motor, and the light tracker and fault alarm are electrically connected to the controller inside the control module housing.

[0011] Preferably, the surface of the self-tracking solar collector is provided with a light-transmitting protective plate to protect the collector tube, and the two ends of the collector tube are respectively connected to circulation pipes.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] This invention utilizes a combination of a self-tracking solar collector panel, collector tubes, a light tracker, a mounting base, a mounting frame, and an adjustment assembly. In use, the light tracker, installed at the end of the self-tracking solar collector panel, continuously monitors the sun's position and transmits the illumination angle deviation signal to a controller inside the control module housing. The controller then drives a tilting motor and an adjustment motor based on this signal. The tilting motor, in conjunction with a connecting shaft, rotates the mounting frame and the entire collector panel above it in a horizontal plane, achieving solar azimuth angle tracking. Simultaneously, the adjustment motor drives an adjustment screw inside the protective frame, rotating the adjustment seat to adjust the solar azimuth angle. The anti-detachment linkage drives the connecting rod to move. The mounting sleeve at the end of the connecting rod rotates and engages with the mounting linkage at the bottom of the collector plate, thereby pushing the self-tracking solar collector plate to change its pitch angle around the assembly shaft at the end of the mounting frame, so that the surface of the collector plate is always perpendicular to the incident sunlight. Sunlight can shine through the light-transmitting protective plate onto the reflective collector plate, be reflected and concentrated on the collector tube, heating the circulating medium inside the tube. The heat is then output to the heat storage device through the circulation tube. When the light tracker signal is abnormal or the mechanical movement is obstructed, the fault alarm will automatically sound, and at the same time the brake will lock the connecting shaft to prevent the system from continuing to operate under abnormal conditions.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figure 1-6 This invention provides a self-tracking solar thermal collector structure based on the characteristics of strong solar radiation in high-altitude areas, including a self-tracking solar thermal collector plate 1, a heat collection tube 3, a mounting base 10, and a mounting frame 14; the self-tracking solar thermal collector plate 1 has a reflective heat collection plate 2 inside to cooperate with the heat collection tube 3 for heat collection, and a light tracker 6 and a fault alarm 7 are respectively provided at the ends of the self-tracking solar thermal collector plate 1; the top of the mounting base 10 is driven and connected to the mounting frame 14 via a flip motor 15, and one end of the top of the mounting frame 14 is movably connected to the mounting support plate 8 at the bottom of the self-tracking solar thermal collector plate 1, and the surface of the mounting frame 14 is provided with an adjustment component for controlling the angle of the self-tracking solar thermal collector plate 1; the surface of the mounting base 10 is equipped with a flip motor 15 for driving and flipping the position of the mounting frame 14.

[0023] It is worth noting that the system utilizes a coordinated design of the self-tracking solar collector panel 1, collector tube 3, light tracker 6, mounting base 10, mounting frame 14, and adjustment components. The light tracker senses the sun's position in real time, and the combination of the flip motor and adjustment components enables dual-axis automatic tracking, ensuring the collector panel is always at the optimal angle for receiving sunlight. This design, combined with the strong sunlight and high transmittance characteristics of plateau regions, further enhances heat collection, making it suitable for plateau areas with abundant sunshine resources.

[0024] Specifically, the adjustment assembly includes: a protective frame 17 mounted on the surface of the mounting bracket 14, and an adjustment screw 18 rotatably mounted inside the protective frame 17; wherein, the surface of the adjustment screw 18 is connected to an adjustment seat 20, and anti-detachment connecting rods 21 are connected to both sides of the adjustment seat 20, and one end of the mounting bracket 14 is connected to an assembly shaft 16 that cooperates with the assembly support plate 8.

[0025] In addition, the mounting frame 14 is a support structure for assembling the self-tracking solar collector panel 1, the protective frame 17 is a structure for protecting and limiting the adjusting screw 18 and the adjusting seat 20, the adjusting screw 18 can drive the position of the adjusting seat 20 through the adjusting motor 19 to adjust the elevation angle of the self-tracking solar collector panel 1, the anti-detachment connecting rod 21 is a structure that connects to the connecting support rod 22 to prevent loosening, and the mounting sleeve 23 cooperates with the mounting connecting rod 9 to improve the stability of the adjustment of the self-tracking solar collector panel 1.

[0026] An adjusting motor 19 is mounted on the surface of the protective frame 17. The output end of the adjusting motor 19 is connected to the end of the adjusting screw 18. A connecting support rod 22 is rotatably connected to the surface of the anti-detachment connecting rod 21. The other end of the connecting support rod 22 is connected to an installation sleeve 23. An installation connecting rod 9 is mounted on one side of the bottom of the self-tracking solar collector panel 1. The inner wall of the installation sleeve 23 is movably connected to the surface of the installation connecting rod 9.

[0027] Furthermore, the adoption of a purely mechanical transmission system consisting of an adjusting motor 19, an adjusting screw 18, and an anti-detachment linkage 21 effectively avoids the problem of hydraulic system failure or leakage in low-temperature and low-pressure environments. The rotating engagement structure between the anti-detachment linkage 21 and the mounting sleeve 23 ensures smooth and unobstructed angle adjustment, and provides excellent wind resistance, adapting to the harsh environment of high-altitude areas with large diurnal temperature differences and high instantaneous wind speeds.

[0028] A control module housing 11 is mounted on the surface of the mounting base 10. A brake 13 is mounted on one side of the inside of the control module housing 11. A connecting shaft 12, which connects to the mounting bracket 14, is provided on the surface of the mounting base 10. The brake 13 is connected to the end of the connecting shaft 12. The central axis of the connecting shaft 12 is configured to cooperate with the drive shaft of the flip motor 15. The light tracker 6 and the fault alarm 7 are electrically connected to the controller inside the control module housing 11.

[0029] In addition, the brake 13 locks and brakes the connecting shaft 12, and fixes the position of the mounting bracket 14 after adjustment. The flip motor 15 flips the mounting bracket 14 and the self-tracking solar collector 1 installed on it. The controller inside the control module housing 11 is electrically connected to the brake 13 and the flip motor 15, and the brake 13 and the flip motor 15 are assembled inside the control module housing 11, which provides a certain degree of protection. The light tracker 6 is used to sense the sun's direction in real time and provide a precise angle control signal for the automatic tracking of the solar collector.

[0030] The fault alarm 7 integrates an anemometer, which can control the leveling and braking of the heat collector plate via the controller inside the control module housing 11 during strong winds, thus extending the equipment's lifespan. Furthermore, the control module integrates a heating element or low-power standby logic to prevent the lead screw from freezing and jamming in extreme cold. It also features a wireless communication module such as 4G / BeiDou to upload optical tracking data and fault codes to the maintenance center. The fault alarm 7, located at the end of the heat collector plate, is electrically connected to the control module. When the optical tracker 6 signal is abnormal, the motor is overloaded, or the angle adjustment exceeds the safe range, the system can automatically alarm and activate the brake to lock the current posture, preventing equipment damage and reducing maintenance risks in unattended scenarios.

[0031] The self-tracking solar collector panel 1 has a light-transmitting protective plate 5 on its surface to protect the collector tubes 3. Both ends of the collector tubes 3 are connected to circulation pipes 4, and the other end of the circulation pipes 4 is connected to an external heat storage device. The light-transmitting protective plate 5 ensures high light transmittance while reducing the aging effects of ultraviolet radiation and high-altitude dust on the collector tubes and reflective collector panel. A light tracker senses the sun's position in real time, and in conjunction with a flip motor and adjustment components, achieves dual-axis automatic tracking, ensuring the collector panel is always at the optimal angle for receiving sunlight. Combined with the strong sunlight and high transmittance characteristics of high-altitude regions, this design further enhances heat collection and is suitable for high-altitude areas with abundant sunshine resources.

[0032] In use, the light tracker 6 installed at the end of the self-tracking solar collector 1 detects the sun's position in real time and transmits the light angle deviation signal to the controller inside the control module housing 11. The controller drives the flip motor 15 and the adjustment motor 19 according to the signal. The flip motor 15, in conjunction with the connecting shaft 12, drives the mounting frame 14 and the entire collector plate above it to rotate in the horizontal plane, realizing the tracking of the sun's azimuth angle. At the same time, the adjustment motor 19 drives the adjustment screw 18 inside the protective frame 17 to rotate, driving the adjustment seat 20, so that the anti-detachment connecting rod 21 drives the connecting support rod 22 to move. The mounting sleeve 23 at the end of the connecting support rod 22 rotates and engages with the mounting connecting rod 9 at the bottom of the collector plate, thereby pushing the self-tracking solar collector 1 to change the pitch angle around the assembly shaft 16 at the end of the mounting frame 14, so that the surface of the collector plate is always perpendicular to the incident sunlight.

[0033] Sunlight can shine through the light-transmitting protective plate 5 onto the reflective heat collection plate 2, be reflected and concentrated on the heat collection tube 3, heating the circulating medium inside the tube, and the heat is output to the heat storage device through the circulation tube 4; when the light tracker 6 signal is abnormal or the mechanical movement is obstructed, the fault alarm 7 will automatically alarm, and at the same time the brake 13 will lock the connecting shaft 12 to prevent the system from continuing to operate under abnormal conditions.

[0034] The control method of this invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, since this invention is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.

[0035] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
