[0047] As described in the background art, the solar concentrating and thermal collecting system relates to the field of solar concentrating and thermal collecting technology, which generates electricity or provides thermal power by collecting and converting sunlight energy into thermal energy.

[0048] Solar concentrating and thermal collection systems primarily consist of trough reflectors and collector tubes. The trough reflectors focus sunlight and reflect it onto the collector tubes, which absorb the focused solar radiation and convert it into heat.

[0049] However, with the change of seasons, the solar altitude angle varies greatly, causing the focus of sunlight to deviate from the collector tube, reducing the concentration efficiency and affecting the efficiency of thermal energy conversion.

[0050] To address the aforementioned issues, embodiments of the present application provide a seasonally adjustable trough-type concentrating solar collector system, comprising a base; a support member, one end of which is a hinged end hinged to the base, and a reflector disposed on the support member; a lifting assembly disposed on the base and located between the base and the support member, the lifting assembly abutting the other end of the support member, and configured to drive the support member to rotate about the hinged end; and a heat collecting tube located on the concentrating axis of the reflector to absorb sunlight reflected by the reflector. By controlling the lifting assembly to rotate the support member about the hinged end according to changes in the solar altitude angle, the reflector is tilted to increase the incident angle of sunlight, thereby increasing the reflector's concentrating efficiency and improving the amount of solar radiation received by the seasonally adjustable trough-type concentrating solar collector system throughout the year.

[0051] The following describes in detail 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-mentioned technical problems with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0052] Please refer to Figures 1 to 4 This embodiment provides a seasonally adjustable trough-type concentrating solar collector system, comprising a base 100; a support member 200, one end of which is a hinged end hinged to the base 100, and a reflector 400 is disposed on the support member 200; a lifting assembly 300, disposed on the base 100 and located between the base 100 and the support member 200, the lifting assembly 300 abutting against the other end of the support member 200, and configured to drive the support member 200 to rotate about the hinged end; and a heat collecting tube 500, located on the focusing axis of the reflector 400 to absorb sunlight reflected by the reflector.

[0053] Specifically, in this embodiment, base 100 serves as the foundation for the entire seasonally modulated trough concentrating solar system. It is installed on the ground and supports the other components of the seasonally modulated trough concentrating solar system. Base 100 can be a flat plate or frame structure to increase the contact area between base 100 and the ground and ensure support stability.

[0054] In this embodiment, a plurality of height-adjustable feet are provided on the base 100 , and the feet are in contact with the ground, so that the height of the base 100 can be adjusted to adapt to different environments.

[0055] For example, the support legs are provided with threads that cooperate with threaded holes on the base 100 . By rotating the support legs, the relative height between the support legs and the base 100 can be adjusted, thereby achieving adjustment of the overall height of the base 100 .

[0056] In other embodiments, the supporting legs may also adopt other structures capable of achieving height adjustment, and this embodiment does not impose any limitation on this.

[0057] Specifically, in this embodiment, one end of the support member 200 is a hinged end, which is hinged to the base 100. The reflector 400 is arranged on the support member 200, and the heat collecting tube 500 is located on the focusing axis of the reflector 400. The support member 200 can rotate around the hinged end, thereby forming an angle with the base 100, so that the reflector 400 and the heat collecting tube 500 are tilted relative to the base 100, so as to adapt to different solar altitude angles in different seasons, ensuring that the incident angle of sunlight is always within the ideal angle range, thereby ensuring that the seasonally adjusted trough type concentrating solar collector system receives the maximum amount of solar radiation throughout the year.

[0058] In an exemplary embodiment, an axial hole is opened on the hinged end and the base 100, and the pin passes through the axial hole of the support member 200 and is fixed in the axial hole of the base 100 to form a rotating structure to realize the rotation of the support member 200.

[0059] Meanwhile, it should be noted that, in other embodiments, the hinged end may also adopt other hinged structures with the base 100, and this embodiment does not impose any limitation on this.

[0060] Specifically, in this embodiment, the support member 200 is a support plate, thereby providing sufficient installation space for the reflector 400 , and the reflector 400 is disposed on the support plate to drive the reflector 400 to move.

[0061] Specifically, in this embodiment, the lifting assembly 300 is arranged on the base 100, and one end of the lifting assembly 300 abuts against the end of the support member 200 away from the hinged end. When the lifting assembly 300 rises, the lifting assembly 300 can abut against the support member 200 and lift the support member 200 to rotate clockwise around the hinged end of the support member 200, thereby realizing the tilt of the support member 200. When the lifting assembly 300 descends, the lifting assembly 300 can drive the support member 200 to rotate counterclockwise around the hinged end of the support member 200, thereby causing the support member 200 to fall back.

[0062] The lifting assembly 300 may be a hydraulic rod or other structures capable of achieving lifting, and this embodiment does not impose any limitation on this.

[0063] It should be noted that, in this embodiment, the initial states of the lifting assembly 300 and the support member 200 can be set so that the support member 200 is parallel to the base 100 .

[0064] By adopting the above-mentioned technical solution, the lifting assembly 300 can be controlled to rise and fall according to the change of the solar altitude angle, so as to drive the support member 200 to rotate around the hinged end, thereby tilting the reflector 400 relative to the ground to increase the incident angle of sunlight, thereby increasing the focusing efficiency of the reflector 400 and improving the annual solar radiation received by the seasonally adjusted trough concentrating solar collector system.

[0065] Furthermore, in this embodiment, the seasonally adjusted trough type concentrating solar collector system may also include a sensor and a first driving member. The first driving member is used to drive the lifting assembly 300 to rise and fall. The sensor is electrically connected to the first driving member and is used to detect the current solar altitude angle, so that the first driving member drives the lifting assembly 300 to move according to the change of the solar altitude angle to adapt to different solar altitude angles, ensuring that the incident angle of sunlight is always within the ideal angle range, thereby ensuring that the seasonally adjusted trough type concentrating solar collector system receives the maximum amount of solar radiation throughout the year.

[0066] Please refer to Figures 1 to 4 In an optional embodiment, the number of the reflectors 400 and the heat collecting tubes 500 are both multiple, the multiple reflectors 400 are evenly and spacedly rotated and arranged on the support 200, and the multiple heat collecting tubes 500 are arranged one-to-one corresponding to each reflector 400.

[0067] Specifically, in this embodiment, there are multiple reflectors 400 and multiple heat collecting tubes 500. The multiple reflectors 400 are evenly and spaced apart on the support member 200, and each heat collecting tube 500 is arranged one-to-one with each reflector 400, thereby covering a wider solar radiation area and ensuring that more sunlight is effectively captured and focused on the corresponding heat collecting tube 500. At the same time, each heat collecting tube 500 can independently and efficiently absorb the focused solar energy and convert it into heat energy, thereby improving the energy conversion efficiency of the entire seasonally adjusted trough concentrating solar collector system.

[0068] Among them, in this embodiment, the reflector 400 is rotatably set on the support 200, so that when the support 200 drives the reflector 400 to tilt relative to the ground, the reflector 400 can rotate independently, so that the reflector 400 can always maintain the optimal receiving angle for sunlight, thereby improving the flexibility and applicability of the seasonally adjusted trough-type concentrating solar collector system.

[0069] Specifically, in this embodiment, each reflector 400 corresponds to a second driving member, and each reflector 400 can rotate independently under the drive of each second driving member, thereby following the changes in the position of the sun and independently adjusting the receiving angle of sunlight to achieve the best focusing effect.

[0070] The second driving component may be a motor or other device capable of driving, and this embodiment does not impose any limitation on this.

[0071] Please refer to Figures 1 to 4 In an optional embodiment, a plurality of rotation shafts 210 are provided on the support member 200 , and each reflector 400 is provided on each rotation shaft 210 in a one-to-one correspondence and can rotate around the rotation shaft 210 .

[0072] Specifically, in this embodiment, a plurality of rotation axes 210 are provided on the support member 200 , and each reflector 400 is provided on each rotation axis 210 in a one-to-one correspondence, so that the reflector 400 can rotate around the rotation axis 210 , thereby more accurately tracking the position change of the sun.

[0073] Specifically, since each reflector 400 corresponds one-to-one to each rotating shaft 210, each reflector 400 can be adjusted independently, ensuring that the reflector 400 is always facing the sun and that the incident angle of the sun is at the optimal angle, thereby maximizing the reception of solar radiation and focusing it on the corresponding heat collecting tube 500.

[0074] Please refer to Figures 1 to 4 In an optional embodiment, the seasonally adjusted trough-type concentrating solar collector system further includes two heat conducting pipes 600 and a plurality of transmission pipes 700 , wherein both ends of the transmission pipe 700 are respectively connected to two adjacent heat collecting pipes 500 , and the two heat conducting pipes 600 are respectively connected to the two heat collecting pipes 500 located on both sides.

[0075] Specifically, in this embodiment, the two heat conducting pipes 600 are respectively connected to the two heat collecting pipes 500 located on both sides, and each adjacent two heat collecting pipes 500 are connected through the transmission pipe 700. The heat conducting pipes 600 and the transmission pipe 700 are filled with a heat storage medium, so that the heat storage medium is transferred to the heat collecting pipe 500 for heating, and then the heat stored in the heat storage medium is exchanged with external power generation equipment or equipment that needs to be heated, thereby realizing the effective utilization of solar energy.

[0076] Specifically, in this embodiment, the two heat pipes 600 are arranged to be interconnected, forming a closed-loop pipeline with the heat collecting pipe 500 and the transmission pipe 700. The heat pipe 600 on one side is filled with a room temperature heat storage medium, so that the heat storage medium can enter the heat collecting pipe 500 through the transmission pipe 700, so that it enters the heat collecting pipe 500 to absorb solar thermal energy. After absorbing sufficient solar thermal energy, the heat storage medium is transmitted to the heat pipe 600 on the other side and exchanges heat with external power generation equipment or equipment that needs to be heated. In this process, the heat in the heat storage medium is gradually released, the temperature gradually decreases, and finally returns to the heat pipe 600 at the initial position, and is then retransmitted to the heat collecting pipe 500 for heating, thereby achieving the function of storing and transmitting heat energy through the heat storage medium and realizing the recycling of the heat storage medium.

[0077] The heat storage medium can be molten salt or thermal oil.

[0078] At the same time, it should be noted that, in order to ensure the smooth flow of the heat storage medium, a circulation pump can be provided on the heat pipe 600 and the transmission pipe 700 to drive the flow of the heat storage medium.

[0079] Please refer to Figures 1 to 4 In an optional embodiment, the heat pipe 600 has a telescopic portion 611 , which can be telescoped to adjust the length of the heat pipe 600 .

[0080] Specifically, when the lifting assembly 300 drives the support member 200 to rotate, the heat collecting pipe 500, which is mounted on the support member 200, will also tilt relative to the base 100 under the influence of the support member 200, thereby causing the distance between the heat collecting pipe 500 and the heat conducting pipe 600 to change. Therefore, in this embodiment, the heat conducting pipe 600 has an expansion portion 611 that can be expanded and contracted to adjust the length of the heat conducting pipe 600.

[0081] Specifically, in this embodiment, when the support member 200 drives the heat collecting pipe 500 to rotate in a clockwise direction, the distance between the heat collecting pipe 500 and the heat conducting pipe 600 increases, and the telescopic portion 611 can be extended at this time, thereby increasing the length of the heat conducting pipe 600; when the support member 200 drives the heat collecting pipe 500 to rotate in a counterclockwise direction, the distance between the heat collecting pipe 500 and the heat conducting pipe 600 is reduced, and the telescopic portion 611 can be compressed at this time to shorten the length of the heat conducting pipe 600 to adapt to the change in the distance between the heat collecting pipe 500 and the heat conducting pipe 600.

[0082] The telescopic portion 611 may be a pleated structure, and the length of the heat pipe 600 may be adjusted by expanding and contracting the pleats.

[0083] In other embodiments, the telescopic portion 611 may also be other structures capable of achieving telescopic movement, and this embodiment does not impose any limitation on this.

[0084] Please refer to Figures 2 to 5 In an optional embodiment, the heat pipe 600 includes a first sub-pipe 610 and a second sub-pipe 620 that are connected to each other. The first sub-pipe 610 is connected to the heat collecting pipe 500. The first sub-pipe 610 and the second sub-pipe 620 are rotatably connected. The second sub-pipe 620 is used to connect to external equipment.

[0085] Specifically, in this embodiment, the first sub-tube 610 is used to connect to the heat collecting tube 500, and the second sub-tube 620 is used to communicate with external equipment. The first sub-tube 610 and the second sub-tube 620 are rotatably connected. When the lifting assembly 300 drives the support 200 to rotate, the heat collecting tube 500 is installed on the support 200 and the heat collecting tube 500 is also driven by the support 200 to tilt relative to the base 100, resulting in a change in the height of the heat collecting tube 500. Therefore, by rotatably connecting the first sub-tube 610 and the second sub-tube 620, the height change of the heat collecting tube 500 can be accommodated.

[0086] Specifically, when the support member 200 drives the heat collecting tube 500 to rotate in a clockwise direction, the distance between the heat collecting tube 500 and the heat conducting tube 600 increases. At this time, the first sub-tube 610 and the second sub-tube 620 rotate relative to each other, so that the angle between the two increases to adapt to the height change of the heat collecting tube 500; when the support member 200 drives the heat collecting tube 500 to rotate in a counterclockwise direction, the distance between the heat collecting tube 500 and the heat conducting tube 600 decreases. At this time, the first sub-tube 610 and the second sub-tube 620 rotate relative to each other, so that the angle between the two becomes smaller to adapt to the height change of the heat collecting tube 500.

[0087] It should be noted that, in this embodiment, the first sub-tube 610 and the second sub-tube 620 are connected via a rotary joint. In other embodiments, the first sub-tube 610 and the second sub-tube 620 may also be connected in rotation via other structures, and this embodiment does not impose any limitation on this.

[0088] In addition, it should be noted that, in this embodiment, the external device may be a storage tank for the heat storage medium to transfer the heat storage medium into the heat pipe 600, or may be other external devices, and this embodiment does not impose any restrictions on this.

[0089] Please refer to Figure 1 、 Figure 3 and Figure 5 In an optional embodiment, the seasonally adjusted trough-type concentrating solar collector system further includes a bracket 800 disposed on the support member 200 , and the heat collecting tube 500 is disposed on the bracket 800 .

[0090] Specifically, in this embodiment, the heat collecting tube 500 is set on the support 200 through the bracket 800, thereby ensuring that the heat collecting tube 500 can rotate with the support 200, ensuring that the heat collecting tube 500 can always be located on the focusing axis of the reflector 400, avoiding the heat collecting tube 500 from being offset, and ensuring the stability and consistency of the focusing effect.

[0091] Specifically, in order to further ensure the stability of the heat collecting pipe 500, a clamp or a clamp can be provided on the heat collecting pipe 500 to install the heat collecting pipe 500 on the bracket 800. This embodiment does not impose any restrictions on this.

[0092] In addition, in other embodiments, the bracket 800 can also be set on the reflector 400 to ensure that the heat collecting tube 500 can always be located on the focusing axis of the reflector 400, avoiding the displacement of the heat collecting tube 500 and ensuring the stability and consistency of the focusing effect.

[0093] Please refer to Figure 1 、 Figure 3 and Figure 5 In an optional embodiment, the bracket 800 includes at least two support rods 810, the support rods 810 are arranged on the support member 200, and the heat collecting tubes 500 are arranged at the top ends of the support rods 810; and a reinforcement member 820, the two ends of the reinforcement member 820 are respectively connected to two of the support rods 810.

[0094] Specifically, in this embodiment, the bracket 800 includes two support rods 810 arranged at intervals, the heat collecting tube 500 is arranged at the top end of the support rod 810, and the reinforcement 820 is arranged between the two support rods 810 to enhance the stability of the bracket 800.

[0095] There may be multiple reinforcement members 820 , and the multiple reinforcement members 820 are evenly arranged between the two support rods 810 .

[0096] In an exemplary embodiment, a triangular structure is formed between two adjacent reinforcement members 820 and one of the support rods 810 .
