[0024] The utility model aims to provide a solar thermal collector to solve the problems existing in the prior art, meet the electricity demand through solar power generation and achieve self-sufficiency.
[0025] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0026] Embodiment 1
[0027] This embodiment provides a solar thermal collector, such as Figure 1 to Figure 5 As shown, it includes a trough collector assembly and a solar energy collector device; the trough collector assembly has a rectangular support frame 1 and a column assembly 2 for supporting the support frame 1, and multiple rows of trough parabolic reflector collector units 11 are fixedly arranged on the two long sides of the support frame 1; the solar energy collector device includes a first solar panel 3, a battery device and a collector controller, the first solar panel 3 is arranged on the short side of the support frame 1 and extends outward, and the first solar panel 3 is fixed to the support frame 1 through a first connecting bracket 31, and the first solar panel 3 can rotate with the trough parabolic reflector collector unit 11 following the sun's azimuth; the battery device and the collector controller are fixed on the column assembly 2, and the collector controller is electrically connected to the first solar panel 3, the battery device and the electrical equipment of the trough collector assembly.
[0028] By adding a first solar panel 3 to the empty position on the short side of the rectangular support frame 1 on the original trough collector assembly, it can rotate with the sun's position together with the trough parabolic reflector collector unit 11, so as to receive solar energy more efficiently, and store it in a battery device through the control of a collector controller, and then supply the electric energy to various electrical equipment on the trough collector assembly through voltage conversion of the collector controller; the electricity demand is met by solar power generation, and self-sufficiency is achieved; and the structure is simple, and it only needs to be installed on the basis of the original structure. The first solar panel 3 rotates with the sun's position together with the trough parabolic reflector collector unit 11, so it does not affect the original heat collection effect of the original trough parabolic reflector collector unit 11, and the structure is simple and practical.
[0029] Specifically, the collector controller has two functions: first, to prevent the first solar panel 3 and the second solar panel 4 from overcharging the battery device or over-discharging the battery device, thereby protecting the battery, improving battery efficiency, and extending system life; second, the voltage conversion function, in which the electric energy supplied by the battery device is converted by the voltage of the collector controller to meet the different voltage requirements of different electrical equipment; and the collector controller and the battery device can be a single component, which is used to be fixed at the corresponding position of the column assembly 2, or it can be integrated into the electrical control cabinet 21 in the trough collector assembly.
[0030] Specifically, the trough collector assembly is an existing structural member, and its structure and function are the same as those of patent CN115727553A-a double-axis trough solar collector, so it will not be repeated here; the solar collector of this embodiment is obtained by adding a solar energy collection device to this structure, wherein the support frame 1 is the wind-resistant frame in patent CN115727553A-a double-axis trough solar collector, which is a square frame.
[0031] Specifically, the connection between the support frame 1 and the column assembly 2 is also an existing structure, which is the same as the connection structure at the corresponding position in patent CN115727553A-a double-axis trough solar collector, and will not be repeated here.
[0032] Specifically, the electrical equipment of the trough collector assembly includes but is not limited to the following components: a rotary reducer used to achieve rotation around the solar azimuth angle, an electric push rod used to rotate around the solar altitude angle, and some electrical components for control and monitoring.
[0033] Among the optional solutions of this embodiment, it is more preferred that Figure 1-2As shown, a second solar panel 4 extending outward is provided on the other short side of the support frame 1 opposite to the first solar panel 3. The second solar panel 4 is fixed to the support frame 1 through a second connecting bracket 41. The second solar panel 4 is electrically connected to the power collection controller and the battery device. The first solar panel 3 and the second solar panel 4 are respectively provided on the two short sides of the support frame 1, which can increase the receiving area of solar energy and improve the effect of solar energy collection.
[0034] Specifically, the positions covered by the first solar panel 3 and the second solar panel 4 do not affect the heat collection effect of the reflectors and vacuum heat collection tubes in the original parabolic trough reflector heat collection unit 11 .
[0035] Specifically, the structures of the first connecting bracket 31 and the second connecting bracket 41 are not limited, as long as they can install the corresponding first solar panel 3 and the second solar panel 4 and connect and fix on the supporting frame 1, including but not limited to the following: Figure 4 and Figure 5 The structure shown in the figure includes a fixing frame 5 for mounting the corresponding first solar panel 3 and second solar panel 4 and a connecting rod 6 between the fixing frame 5 and the supporting frame 1.
[0036] Specifically, the first solar panel 3 is fixed to the first connecting bracket 31 by bolts, and the second solar panel 4 is fixed to the second connecting bracket 41 by bolts. The position and number of connection points are not limited and can be determined according to the actual fixing effect and the solar energy receiving effect of the first solar panel 3 or the second solar panel 4.
[0037] Specifically, the first solar panel 3 and the second solar panel 4 can be formed by a whole piece or by splicing multiple solar panels. When they are spliced together, a gap of not less than 45 mm should be left between two adjacent solar panels. For the same windward area, the wind resistance of the spliced solar panels with air vents is reduced compared with that of a whole solar panel. Similarly, the reflector on the single long side of the supporting frame 1 of the trough parabolic reflector collector unit 11 on the trough collector assembly can also be spliced together by multiple pieces, and a gap of not less than 45 mm should be left between adjacent splicing locations.
[0038] The present invention uses specific examples to illustrate the principle and implementation of the present invention. The above examples are only used to help understand the method and core idea of the present invention. At the same time, for those skilled in the art, according to the idea of the present invention, there will be changes in the specific implementation and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
