Description

Technical Field

[0001] The invention relates to the field of solar energy utilization equipment, and in particular to a foldable heliostat. Background Art

[0002] In solar energy utilization technology, heliostat is one of the most important devices. As the focusing component in the tower solar thermal power generation system, the function of the heliostat in the tower solar power generation technology is to track the trajectory of the sun and then focus the sunlight to reflect it onto the collector, thereby realizing energy transfer. It is a key component of energy transfer.

[0003] In many outdoor environments where heliostats are installed, dust is a common problem. For example, in desert fringe areas, frequent wind and sand activities can fill the air with a large number of tiny dust particles. These dust particles can easily adhere to the reflective lenses of the heliostats, and due to the large number of them, a thick layer of dust will form on the surface of the lenses. The existing heliostat structure is usually complex, containing a large number of mechanical parts and electronic control components. When it is necessary to maintain the heliostats, such as cleaning the lenses or repairing the mechanical transmission parts, professional technicians and specific tools are often required. For large heliostat fields, maintenance personnel need to check and handle each heliostat one by one, which is cumbersome and time-consuming. Moreover, since heliostats are usually installed in large-area arrays, they may be blocked and interfered by surrounding heliostats during maintenance operations, further increasing the difficulty of maintenance. Heliostats are usually installed in areas with rich solar energy resources, which are often far away from cities and densely populated areas, such as desert areas, Gobi Desert or some high-altitude wilderness. Their remote geographical location leads to inconvenient transportation, which makes it difficult for maintenance personnel and maintenance equipment to quickly reach the site for maintenance operations.

[0004] Over time, this layer of dust will become very compact and difficult to remove by simple wind blowing or natural falling. Even a small amount of dust attached will significantly reduce the reflectivity of the lens, affecting the focusing effect of the heliostat, and thus reducing the power generation efficiency of the entire solar thermal system. Existing heliostats lack effective countermeasures when facing these problems, and there is an urgent need for a heliostat design that can protect itself in harsh environments and is easy to maintain.

[0005] Although the prior art such as CN117872560A discloses a foldable heliostat, the design is provided with a plurality of horizontally arranged sub-mirrors, and the adjacent sub-mirrors are hingedly connected. The plurality of sub-mirrors can be unfolded and folded in a mirror frame assembly. The heliostat can be folded up to be in a protective posture to reduce damage to the mirror surface. However, the folding efficiency of the mirror is not high because the adjacent sub-mirrors are hingedly connected, the torque is too long, and the mirror is easily damaged by wind and sand.

[0047] The present invention is described in detail and specifically by specific examples below to provide a better understanding of the present invention, but the following examples do not limit the protection scope of the present invention.

[0048] Example 1

[0049] This embodiment discloses a foldable heliostat.

[0050] like Figures 1 to 12 As shown, this embodiment includes a heliostat body 1, which includes a support column 11, a plurality of lenses, the lenses are petal-shaped, and the plurality of lenses form a circular mirror surface. A plane deflection structure 4 is provided on the top of the support rod, a plane rotation structure 5 is provided on the bottom of the support rod, and a rotation mechanism 3 is provided at the end of the lens, and the rotation mechanism 3 is flip-connected with the plane deflection structure 4;

[0051] The lens includes an inner lens 12 and an outer lens 13. An inner lens support 14 is provided at the bottom of the inner lens 12, and an outer lens support 15 is provided at the bottom of the outer lens 13. The inner lens 12 and the outer lens 13 are rotatably connected with the inner lens support 14 and the outer lens support 15. A folding mechanism 2 is provided between the inner lens support 14 and the outer lens support 15. The lens is flipped downward by the rotating mechanism 3 and the plane rotating structure 5. The inner lens 12 and the outer lens 13 are wrapped around the support rod through the folding mechanism 2 to form a closed storage structure.

[0052] This embodiment is provided with 6 mirrors, and the design inspiration of this foldable heliostat comes from water lilies. The 6 reflectors are bionic 6 water lily petals, and the support column 11 is bionic stem of water lily. The push rod is used to fold and stabilize. After folding, the whole presents a streamlined shape, which greatly reduces the wind resistance when sandstorms and strong winds come, and protects the mirror surface from being damaged by strong winds and strong sand.

[0053] The support column 11 serves as the support base of the entire heliostat and plays the role of supporting the lens and other mechanisms. The support column 11 is designed with strength and stability in mind to ensure that the heliostat can be stably supported under various environmental conditions. The lens is composed of an inner lens 12 and an outer lens 13, which are arranged on the top of the support column 11. An inner lens support 14 is installed at the bottom of the inner lens 12, and an outer lens support 15 is installed at the bottom of the outer lens 13. The inner lens 12 and the outer lens 13 are rotatably connected to the outer lens support 15 through the inner lens support 14. Several inner lenses 12 and outer lenses 13 together form a circular mirror surface, and this circular mirror surface design helps to better reflect and concentrate sunlight.

[0054] The folding mechanism 2 includes a first electric push rod 21, a long rod 22, an L-shaped short rod 23, a connecting rod 24, and a supporting short rod 25. The first electric push rod 21, the long rod 22, and the L-shaped short rod 23 are arranged in the inner mirror support 14, the supporting short rod 25 is arranged in the outer mirror support 15, and the connecting rod 24 connects the L-shaped short rod 23 and the supporting short rod 25.

[0055] One end of the push rod is fixed to the top wall of the inner mirror support 14, and the other end of the push rod is connected to one end of the long rod 22. Both ends of the long rod 22 are connected to one end of the L-shaped short rod 23. The L-shaped short rod 23 is rotatably connected to the top wall of the inner mirror support 14. The other end of the L-shaped short rod 23 is connected to the supporting short rod 25 through a connecting rod 24. The top of the supporting short rod 25 is fixed to the top wall of the outer mirror support 15.

[0056] The folding mechanism 2 is located in the inner mirror support 14 and the outer mirror support 15, and its main components include a first electric push rod 21, a long rod 22, an L-shaped short rod 23, a connecting rod 24 and a supporting short rod 25. One end of the first electric push rod 21 is fixed to the top wall of the inner mirror support 14, and the other end is connected to one end of the long rod 22. Both ends of the long rod 22 are connected to one end of the L-shaped short rod 23, and the L-shaped short rod 23 is rotatably connected to the top wall of the inner mirror support 14. The other end of the L-shaped short rod 23 is connected to the supporting short rod 25 arranged in the outer mirror support 15 through the connecting rod 24, and the top of the supporting short rod 25 is fixed to the top wall of the outer mirror support 15. Through the telescopic movement of the first electric push rod 21, the long rod 22, the L-shaped short rod, the connecting rod 24 and the supporting short rod 25 can be driven to work together, thereby realizing the folding and flipping action of the inner lens 12 relative to the outer lens 13, so that the inner lens 12 can be accurately folded and flipped onto the outer lens 13.

[0057] The heliostat body 1 further includes a rotating mechanism 3, which connects the support rod and the inner mirror support 14, and the heliostat body 1 rotates the mirror through the rotating mechanism 3;

[0058] The rotating structure includes a rotating support 31, and a first large torque servo 32 is arranged inside the rotating support 31. The first large torque servo 32 includes a first fixed end 33 and a first rotating shaft 34. The first fixed end 33 is fixed on the rotating support 31, and a first bevel gear 35 is arranged on the first rotating shaft 34. A fixing rod 36 is arranged at the end of the endoscope support 14, and a second bevel gear 37 is arranged at the end of the fixing rod 36. The first bevel gear 35 is meshed with the second bevel gear 37, and the first bevel gear 35 and the second bevel gear 37 are arranged in the rotating support 31.

[0059] The rotating support 31 is the core bearing component of the entire rotating mechanism 3. It is cast from a high-strength alloy material with a certain toughness. Its internal structure is precisely designed to provide a stable mounting base for the first large torque servo 32. The first large torque servo 32 becomes the power for the lens to rotate by virtue of its own powerful torque output capability. The first fixed end 33 is closely connected to the rotating support 31 through a special fastening bolt to ensure that the servo will not be displaced or loosened under high-speed rotation and complex force conditions. The first bevel gear 35 on the first rotating shaft 34 is precisely meshed with the second bevel gear 37 on the fixed rod 36 at the end of the end mirror support 14. Compared with the traditional spur gear, this bevel gear transmission method has higher load-bearing capacity, smoother transmission characteristics and less noise generation. During the rotation process, the two bevel gears cooperate with each other to efficiently and accurately transmit the rotational power of the servo to the end mirror support 14, thereby driving the entire lens to achieve a smooth rotation movement. Operators can pre-set the angle value based on the actual space layout and storage requirements on site, so that the lenses can be accurately rotated to the most suitable angle for storage and folding.

[0060] The planar deflection structure 4 includes a port 41 and a support platform 42 . The bottom of the port 41 is sleeved on the top of the support rod, and the port 41 is rotatably connected to the support platform 42 .

[0061] Two intersection seats 47 are provided at the top of the port 41, and two intersection plates 48 are provided at the bottom of the support platform 42. The intersection seat 47 is rotatably connected with the intersection plate 48. The plane deflection structure 4 also includes a second large torque servo 43. The second large torque servo 43 includes a second fixed end and a second rotating shaft. The second fixed end is fixed on the intersection plate 48, and the second rotating shaft connects the intersection plate 48 and the intersection seat 47.

[0062] As a key transition component connecting the support rod and the support platform 42, the port 41 is made of high-strength aluminum alloy and is formed by precision forging and machining to ensure that its bottom is tightly and firmly connected to the top of the support rod and can withstand various loads from above. Its inner wall is designed with special anti-slip patterns to further enhance the friction with the support rod and prevent loosening or displacement during frequent deflection movements. The support platform 42 is made of a composite material with both rigidity and toughness. While ensuring sufficient strength to support the lens and related components, it effectively reduces the overall weight and facilitates the flexible adjustment of the heliostat. In the actual solar thermal utilization process, the solar altitude angle is always in dynamic change. This plane deflection structure 4 can respond to this change in real time and accurately by virtue of the second largest torque servo 43 on both sides. When the sun rises or falls, the control system quickly sends instructions to the second largest torque servo 43 based on the data collected by the light sensor. The servo is started, and its second rotating shaft drives the port 41 to adjust the angle relative to the support platform 42, thereby causing the lens to change its inclination angle accordingly.

[0063] A plurality of first shaft plates 311 are evenly arranged on the top of the support platform 42 , a first shaft seat 312 is arranged on the bottom of the rotating support member 31 , and the bottom of the rotating support member 31 and the top of the support platform 42 are rotatably connected through the first shaft plates 311 and the first shaft seat 312 .

[0064] A plurality of second electric push rods 44 are provided on the top of the support platform 42, and the second electric push rods 44 include an electric push rod base 45 and an electric push rod telescopic shaft 46. A second shaft plate 313 is provided at the bottom of the electric push rod, and a plurality of second shaft seats 314 are provided around the support platform 42. The bottom of the electric push rod is connected to the support platform 42 through the second shaft plate 313 and the second shaft seat 314, and the top end of the electric push rod telescopic shaft 46 is connected to the bottom of the rotating support member 31, and the second electric push rod 44 drives the rotating mechanism 3 to flip downward.

[0065] After receiving the storage instruction, each second electric push rod 44 starts synchronously, and the electric push rod telescopic shaft 46 gradually shrinks, pulling the bottom of the rotating support 31 to move downward. Since the rotating support 31 is rotatably connected to the top of the support platform 42, the rotating support 31 drives the lens to slowly turn down with the connection point as the axis. As all the lenses gradually turn down, an umbrella-like storage structure is finally formed. This umbrella-like storage structure has many advantages: first, compared with the traditional planar storage method, it greatly reduces the occupied space in the vertical direction, and can accommodate more heliostats in a limited storage space; second, the lenses after turning down block each other, providing an additional protective barrier for the lenses, effectively resisting the erosion of the lenses by severe weather such as wind, sand, rain, etc., and further extending the service life of the lenses; third, during the unfolding and storage process, the umbrella-like structure has a more reasonable mechanical distribution, which reduces the impact on mechanical components, and is conducive to maintaining the stability of the entire heliostat system and ensuring its long-term reliable operation.

[0066] The planar rotating structure 5 includes a support seat 51, a transmission gear 52 is arranged inside the support seat 51, the bottom of the support rod penetrates into the support seat 51 and is connected to the transmission gear 52, a bearing 53 is arranged at the junction of the support rod and the support seat 51, four steering gears 54 are evenly arranged around the transmission gear 52, the four steering gears 54 are meshed with the transmission gear 52, and a reduction motor 55 is arranged on the steering gear 54, and the reduction motor 55 drives the steering gear 54 to rotate.

[0067] The transmission gear 52 is located at the center of the support seat 51 and is made of high-quality alloy steel material with high hardness, high strength and good wear resistance to ensure that it can work stably and reliably during long-term and frequent rotation transmission. Four steering gears 54 are evenly distributed around the transmission gear 52 and precisely mesh with the transmission gear 52. The steering gear 54 is also made of high-strength alloy steel, and the tooth shape is precisely processed to ensure the accuracy and reliability of meshing and avoid problems such as tooth surface wear, jamming or tooth skipping during the transmission process. A reduction motor 55 is installed on each steering gear 54. The reduction motor 55 uses a motor with high torque output and low speed characteristics, and is equipped with a suitable reducer to meet the torque and speed requirements of the heliostat during rotation. The reduction motor 55 is fixed to the support seat 51 by bolts or other reliable connection methods, and its output shaft is tightly connected to the steering gear 54 to ensure that power can be efficiently transmitted to the steering gear 54, thereby driving the transmission gear 52 and the support rod to rotate. When the heliostat needs to be rotated in a plane, the control system sends corresponding control signals to the four reduction motors 55 according to the change in the azimuth of the sun or other preset instructions, so that the reduction motors 55 are started at the same time and drive the steering gear 54 to rotate. Due to the meshing relationship between the steering gear 54 and the transmission gear 52, the rotational motion of the steering gear 54 will be converted into the rotational motion of the transmission gear 52, thereby driving the support rod and the heliostat to rotate in the horizontal plane, thereby achieving accurate tracking and positioning of sunlight.

For those skilled in the art, any equivalent modifications and substitutions made to the present invention are also within the scope of the present invention. Therefore, the equalization changes and modifications made without departing from the spirit and scope of the present invention should be included in the scope of the present invention.
