[0055] As the consumption of fossil energy and the problem of climate change caused by greenhouse gas emissions are becoming increasingly serious, solar energy, as a clean and renewable energy, has received extensive attention. The solar light concentrating and heat collecting device relates to the technical field of solar light concentrating and heat collecting, which collects and converts solar light energy into heat energy for power generation or providing heat power.

[0056] The solar light concentrating and heat collecting device mainly comprises a trough-shaped reflector and a heat collecting pipe. The trough-shaped reflector is used to focus and reflect sunlight to the heat collecting pipe, and the heat collecting pipe is used to absorb the focused solar radiation energy and convert it into heat energy.

[0057] However, in actual application, the position of the sun is not fixed. With the change of seasons, the altitude angle of the sun changes, which causes the focus point of the sunlight reflected by the reflector to deviate from the heat collecting pipe, thereby reducing the light concentrating efficiency of the solar light concentrating device and the heat energy conversion efficiency.

[0058] To solve the above problems, the embodiments of the present application provide a double-axis tilting solar light concentrating device, which comprises a base; a reflector arranged on the base, the reflector being used to reflect sunlight; a double-axis tilting assembly arranged on the base and connected with the reflector, the double-axis tilting assembly being configured to drive the reflector to rotate around the east-west direction and / or the south-north direction; and a heat collecting pipe located on the light concentrating axis of the reflector to absorb the sunlight reflected by the reflector. By controlling the double-axis tilting assembly to drive the reflector to rotate according to the change of the altitude angle of the sun, the reflector can be tilted to follow the change of the altitude angle of the sun, so as to increase the incident angle of the sunlight, thereby increasing the light concentrating efficiency of the reflector and improving the annual solar radiation received by the double-axis tilting solar light concentrating device.

[0059] The technical solutions of the embodiments of the present application and how the technical solutions of the embodiments of the present application solve the above technical problems will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes can not be described again in some embodiments. The embodiments of the embodiments of the present application will be described below with reference to the drawings.

[0060] Please refer toFigure 1 、 Figure 2 and Figure 3 . The embodiment provides a biaxial tilting solar light condensing device, which comprises a base 100; a reflector 200 arranged on the base 100, the reflector 200 being used for reflecting sunlight; a biaxial tilting assembly 300 arranged on the base 100 and connected with the reflector 200, the biaxial tilting assembly 300 being configured to drive the reflector 200 to rotate around the east-west direction and / or the south-north direction; and a heat collecting pipe 400 located on a light condensing axis of the reflector 200 to absorb the sunlight reflected by the reflector 200.

[0061] Specifically, in the embodiment, the base 100 is the basis of the whole biaxial tilting solar light condensing device, is arranged on the ground, and is used for supporting the reflector 200 and the biaxial tilting assembly 300. The base 100 can be a flat plate structure or a frame structure to increase the contact area of the base 100 with the ground and ensure the stability of the support.

[0062] Specifically, due to the rotation of the earth, the sun moves from east to west in a day, and due to the revolution of the earth and the inclination of the earth axis, the position of the sun in the sky will shift north and south with the change of seasons. Therefore, in the embodiment, the biaxial tilting assembly 300 drives the reflector 200 to rotate along the east-west direction and / or the south-north direction, so as to accurately adjust the rotation angle of the reflector 200 according to the real-time position of the sun, ensure that the reflector 200 always faces the sun, and maximize the incidence angle of the sunlight, thereby maximizing the receiving area and condensing efficiency of the sunlight.

[0063] It should be noted that the biaxial tilting assembly 300 can independently control the two rotation directions of the reflector 200. Specifically, the biaxial tilting assembly 300 can control the reflector 200 to rotate along the east-west direction alone, can control the reflector 200 to rotate along the south-north direction alone, or can control the reflector 200 to rotate along the east-west direction and the south-north direction simultaneously, so as to adapt to different solar elevation angles and enable the sunlight to be accurately focused on the heat collecting pipe 400.

[0064] The biaxial tilting assembly 300 can be a universal joint structure to realize rotation along the east-west direction and / or the south-north direction. In other embodiments, the biaxial tilting assembly 300 can also be other structures capable of realizing independent or simultaneous rotation in two directions, and the embodiment does not make any limitation in this regard.

[0065] By adopting the above technical scheme, the biaxial tilting assembly 300 can be controlled to drive the reflector 200 to rotate according to the change of the solar elevation angle, so as to tilt the reflector 200 relative to the ground to increase the incidence angle of the sunlight, thereby increasing the condensing efficiency of the reflector 200 and improving the annual solar radiation received by the biaxial tilting solar light condensing device.

[0066] In addition, in other embodiments, a plurality of dual-axial tilt solar light condensing devices can be arranged in an array, and by reasonably planning the position and spacing of each dual-axial tilt solar light condensing device, the limited land resources can be fully utilized, and the power generation efficiency of the overall system can be improved.

[0067] In the embodiment, the bases 100 of two adjacent dual-axial tilt solar light condensing devices can be connected by a transverse connecting rod, so as to connect a plurality of dual-axial tilt solar light condensing devices into a whole, thereby improving the rigidity of the whole system and ensuring the stability of the structure.

[0068] Please refer to Figures 1 to 5 In an optional embodiment, the dual-axial tilt assembly 300 comprises:

[0069] The first support 310 is connected with the reflector 200;

[0070] The first rotating shaft 320 is arranged on the first support 310 and is arranged in the east-west direction;

[0071] The first driving member 330 is configured to drive the first rotating shaft 320 to rotate, so as to drive the reflector 200 to rotate in the east-west direction;

[0072] The second support 340 is connected with the base 100;

[0073] The second rotating shaft 350 is arranged on the second support 340 and is arranged in the south-north direction;

[0074] The second driving member 360 is configured to drive the second rotating shaft 350 to rotate, so as to drive the reflector 200 to rotate in the south-north direction;

[0075] The connecting member 370 is located between the first driving member 330 and the second driving member 360 and is connected with the first driving member 330 and the second driving member 360, respectively.

[0076] Specifically, in the embodiment, the first support 310 is connected with the reflector 200, and the first driving member 330 is capable of driving the first rotating shaft 320 arranged on the first support 310 to rotate, so that the first rotating shaft 320 drives the reflector 200 to rotate along the east-west direction through the first support 310. Correspondingly, the second driving member 360 is connected with the first driving member 330 through the connecting member 370, and the second driving member 360 is capable of driving the rotating shaft arranged on the second support 340 to rotate. At this time, since the second support 340 is fixedly arranged on the base 100, the second driving member 360 itself is capable of rotating along the south-north direction under the driving of the second driving member 360, so as to drive the first driving member 330, the first support 310 and the reflector 200 to rotate along the south-north direction through the connecting member 370. Further, the two rotating directions of the reflector 200 are independently controlled through the arrangement of the first driving member 330 and the second driving member 360, so as to adapt to different solar elevation angles and enable the sunlight to be accurately focused on the heat collecting pipe 400, thereby ensuring the light collecting efficiency of the reflector 200 and improving the annual solar radiation received by the dual-axis tilting solar light collecting device.

[0077] Specifically, in the embodiment, the first driving member 330 and the second driving member 360 are both motors. In other embodiments, the specific specifications and types of the first driving member 330 and the second driving member 360 can be adaptively selected according to needs, and the embodiment does not make any limitation in this regard.

[0078] In an alternative embodiment, the dual-axis tilting assembly 300 further comprises:

[0079] The first driving wheel 331 is connected with the output end of the first driving member 330.

[0080] The first driven wheel 380 is sleeved on the first rotating shaft 320 and cooperates with the first driving wheel 331.

[0081] The second driving wheel 361 is connected with the output end of the second driving member 360.

[0082] The second driven wheel 390 is sleeved on the second rotating shaft 350 and cooperates with the second driving wheel 361.

[0083] Specifically, in the embodiment, the first driving member 330 is connected with the output end of the first driving member 330, so as to be capable of rotating under the driving of the first driving member 330. The first driven wheel 380 is sleeved on the first rotating shaft 320 and is engaged with the first driving wheel 331, so as to be capable of rotating under the driving of the first driving wheel 331, thereby driving the rotating shaft to rotate.

[0084] Specifically, the first driving wheel 331 and the first driven wheel 380 are both helical gears and are arranged perpendicularly to each other, and the first rotating shaft 320 is arranged along the east-west direction. Under the driving of the first driving member 330, the first driven wheel 380 can drive the rotating shaft to rotate along the east-west direction, thereby realizing the rotation of the reflector 200 along the east-west direction. Meanwhile, the helical gears are matched, the load is borne by multiple teeth, the bearing capacity of the gears is improved, and the stability of the transmission is ensured.

[0085] The first supporting member 310 can be directly connected with the first driven wheel 380 or directly connected with the first rotating shaft 320, and the embodiment does not make any limitation in this regard.

[0086] Meanwhile, in the embodiment, the number of the first driving member 330, the first driving wheel 331 and the first driven wheel 380 is two. The two first driving members 330 are arranged on the connecting member 370. The two first driving wheels 331 are respectively connected with the output ends of the two first driving members 330. The two first driven wheels 380 are oppositely arranged at the two ends of the first rotating shaft 320 and are respectively engaged with the two first driving wheels 331. The first supporting member 310 has two connecting portions which are respectively connected with the two first driven wheels 380, thereby ensuring the stability of the reflector 200 when rotating along the east-west direction.

[0087] In addition, it should be noted that, since the two first driven wheels 380 are oppositely arranged, if the reflector 200 is to be driven to rotate by the first driven wheel 380, the two first driven wheels 380 need to be arranged in opposite directions relative to their own rotating directions, that is, the rotating directions of the two first driving wheels 331 need to be oppositely arranged, that is, the rotating directions of the two first driving motors are opposite.

[0088] Correspondingly, the second driving member 360 is connected with the output end of the second driving member 360, thereby being able to rotate under the driving of the second driving member 360. The second driven wheel 390 is sleeved on the second rotating shaft 350 and is engaged with the second driving wheel 361.

[0089] Specifically, the second driving wheel 361 and the second driven wheel 390 are both helical gears and are arranged perpendicularly to each other. The second rotating shaft 350 is arranged along the north-south direction. When the second driving member 360 drives the second driving wheel 361 to rotate, since the second supporting member 340 is fixedly connected with the base 100, the second driving member 360 and the second driving wheel 361 can rotate along the north-south direction under the engagement of the second driven wheel 390, thereby realizing the rotation of the reflector 200 along the north-south direction. Meanwhile, the helical gears are matched, the load is borne by multiple teeth, the bearing capacity of the gears is improved, and the stability of the transmission is ensured.

[0090] The second support member 340 can be directly connected with the second driven wheel 390 or directly connected with the second rotating shaft 350, and the embodiment does not make any limitation on this.

[0091] Meanwhile, in the embodiment, the number of the second driving member 360, the second driving wheel 361 and the second driven wheel 390 is two, the two second driving members 360 are arranged on the connecting member 370, the two second driving wheels 361 are respectively connected with the output ends of the two second driving members 360, the two second driven wheels 390 are oppositely arranged on the two ends of the second rotating shaft 350 and are respectively engaged with the two second driving wheels 361, and the second support member 340 has two connecting portions which are respectively connected with the two second driven wheels 390, thereby ensuring the stability of the reflector 200 when rotating around the north-south direction.

[0092] In addition, it should be noted that, since the two second driven wheels 390 are oppositely arranged, if the reflector 200 is to be rotated under the driving of the second driven wheel 390, the two second driven wheels 390 need to be oppositely arranged with respect to their rotating directions, that is, the rotating directions of the two second driving wheels 361 need to be oppositely arranged, that is, the rotating directions of the two second driving motors are opposite.

[0093] In an optional embodiment, the reflector 200 comprises a mirror surface 210 and a stretching mechanism 220, the mirror surface 210 is arranged on the stretching mechanism 220, and the stretching mechanism 220 is configured to stretch or contract to adjust the reflection focal point of the mirror surface 210.

[0094] Specifically, the mirror surface 210 is responsible for reflecting the sunlight according to a specific angle, that is, focusing the sunlight at the heat collecting pipe 400, so that the heat collecting pipe 400 absorbs and converts solar energy.

[0095] When the reflector 200 is rotated under the driving of the biaxial tilt assembly 300, due to the influence of external environment and the precision limitation of the biaxial tilt assembly 300 itself, the light collecting axis of the reflector 200 may deviate from the heat collecting pipe 400 after rotation, thereby affecting the energy collection efficiency of the heat collecting pipe 400, and if the deviation of the light collecting axis is too large, the heat collecting pipe 400 cannot receive sufficient solar radiation energy, thereby cannot work normally.

[0096] Therefore, in order to solve the above problems, the reflector 200 provided in the embodiment comprises a mirror surface 210 and a stretching mechanism 220, the stretching mechanism 220 can stretch or contract, thereby driving the mirror surface 210 to stretch or contract, and further adjusting the light collecting axis of the mirror surface 210 to be located at the heat collecting pipe 400, so as to ensure that the light collecting focal point is always kept on the heat collecting pipe 400, thereby ensuring the stable operation of the biaxial tilt solar light collecting device.

[0097] In the embodiment, the opening and closing mechanism 220 can be a support structure made of flexible material, and the stretching and contraction of the mirror surface 210 can be achieved by changing the shape and stress state of the flexible material.

[0098] It should be noted that in other embodiments, the structure of the opening and closing mechanism 220 can be adaptively selected according to actual needs, and the present embodiment does not make any limitation in this regard.

[0099] In an exemplary embodiment, the opening and closing mechanism 220 can also use a motor to drive a push rod to move linearly, and the linear motion can be converted into the stretching and contraction of the mirror surface 210 through a conversion mechanism.

[0100] In an alternative embodiment, the opening and closing mechanism 220 includes:

[0101] at least two link assemblies 221, including a first link 2211 and a second link 2212 arranged in cross, the first link 2211 and the second link 2212 are hingedly connected, the first link 2211 is connected to the second link 2212 in the adjacent link assembly 221, and the second link 2212 is connected to the first link 2211 in the adjacent link assembly 221;

[0102] at least two third supports 222, arranged on the link assembly 221, and the mirror surface 210 is arranged on the third support 222;

[0103] a third driving member 223 arranged on one of the first links 2211, and the third driving member 223 is configured to drive the first link 2211 to rotate relative to the second link 2212.

[0104] Specifically, in the embodiment, the link assembly 221 is a unit that constitutes the opening and closing mechanism 220, each link assembly 221 includes a first link 2211 and a second link 2212 arranged in cross, and the third driving member 223 is arranged on one of the first links 2211, so that the first link 2211 and the second link 2212 can rotate relative to each other after being driven by the driving force, and the first link 2211 in each link assembly 221 is connected to the second link 2212 in the adjacent assembly, and the second link 2212 is connected to the first link 2211 in the adjacent assembly, thereby forming a continuous chain with the plurality of link assemblies 221, so that all the link assemblies 221 can work cooperatively to achieve overall stretching or contraction.

[0105] At the same time, since the third support 222 is arranged on the link assembly 221 to support and fix the mirror surface 210, as the link assembly 221 stretches and contracts, the mirror surface 210 can be driven by the third support 222 to change with the movement of the link assembly 221, thereby achieving adjustment of the light axis.

[0129] Secondly, the truss 110 is arranged on the support base 120 to form a solid frame structure. In this embodiment, the truss 110 is composed of a plurality of bar members or beams connected through nodes, so that the truss 110 can disperse forces to each bar member when bearing loads, thereby improving the overall load-bearing capacity and stability.
