Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of solar energy collectors, in particular to a trough type solar energy collector and a support structure thereof. BACKGROUND

[0002] As a renewable and clean energy, solar energy has become a key technology to address global energy crisis and environmental pollution. With the continuous deepening of research on solar energy utilization technology, the trough type solar energy collector (SCE) has occupied an important position in the solar energy utilization system due to its high heat collection capacity and relatively mature technology application. The working principle of the trough type collector is to focus the solar radiation on the collector tube at the focal point position through the parabolic reflector, so that the working medium flowing in the collector tube is heated to generate high temperature medium. The system usually uses a solar tracking device to ensure that the reflector always faces the sun to maximize the heat collection efficiency. The basic components of the trough type solar energy collector include a reflector, a collector tube, a support structure and a tracking device. The reflector is designed in a parabolic shape, which can concentrate a wide range of sunlight onto the collector tube, and the collector tube receives concentrated heat at the focal point of the reflector and heats the working medium.

[0003] The existing trough type solar energy collector single collector loop is composed of multiple solar collector components (SCA), and one SCA is usually composed of dozens of SCEs. A single SCA is generally composed of one driving column and multiple support columns, which is responsible for bearing the vertical load and horizontal wind load of the entire collector and supporting the reflector.

[0071] In a specific embodiment, the first connecting body 101 comprises a first bearing seat and a first rotating shaft 1017 rotatably connected to the first bearing seat, as shown in Figures 4 to 7 The first rotating shaft 1017 is fixedly connected with a first end plate 1016 and a second end plate 1013, at least one of the first end plate 1016 and the second end plate 1013 is used for connecting the main body part of the trough solar collector, and the first bearing seat is connected with the first embedded steel plate 102. In order to reduce the weight of the first rotating shaft 1017 while meeting the requirement of heavy load, the first rotating shaft 1017 is a hollow structure shaft, as shown in Figure 4 and Figure 7 Specifically, the first end plate 1016 and the second end plate 1013 are welded to the two ends of the first rotating shaft 1017. When one of the first end plate 1016 and the second end plate 1013 is used for connecting the main body part of the trough solar collector, it means that the support column 1 is located at the edge position of the solar collector assembly (SCA), and only one side of the end plate is used for connecting the support; when both the first end plate 1016 and the second end plate 1013 are used for connecting the main body part of the trough solar collector, it means that the support column 1 is located at the middle position of the solar collector assembly (SCA), that is, it is arranged between two adjacent main body parts of the trough solar collector, and both sides of the end plate are used for connecting the support.

[0072] Further, the first bearing seat comprises a first connecting bottom plate 1011, a first support seat 1012 and a first shaft cover 1014, the first connecting bottom plate 1011 is arranged at the bottom of the first support seat 1012, the first connecting bottom plate 1011 is used for connecting with the first embedded steel plate 102, and the first rotating shaft 1017 is rotationally connected between the first support seat 1012 and the first shaft cover 1014. In order to realize the rotation support of the first rotating shaft 1017, the position for supporting the first rotating shaft 1017 in the first bearing seat is provided with a bearing bush, and the bearing bush is supported and limited by the first support seat 1012 and the first shaft cover 1014. By arranging the bearing bush to cooperate with the first rotating shaft 1017, the friction is reduced and smooth rotation support is provided. The bearing bush is made of low-friction metal material, which ensures the reliability of long-time operation.

[0073] In an embodiment, the first bearing seat is provided with one, and the first bearing seat is used for supporting the middle position of the first rotating shaft 1017. In other embodiments, the first bearing seat can also be provided with two, and the two first bearing seats are used for supporting the first rotating shaft 1017 at the same time. In order to facilitate maintenance and replacement of parts, the first support seat 1012 and the first shaft cover 1014 are connected by the first connecting bolt 10110. The first connecting bottom plate 1011 is connected with the first embedded steel plate 102 by the second connecting bolt 1018.

[0074] Among them, the bearing bush comprises a first bearing bush 1019 and a second bearing bush 10112, the first bearing bush 1019 is placed on the first support seat 1012 and is used for supporting the lower part of the first rotating shaft 1017, and the second bearing bush 10112 is arranged on the surface of the first shaft cover 1014 close to the first rotating shaft 1017 and is used for pressing the upper part of the first rotating shaft 1017, so as to realize the rotation support of the first rotating shaft 1017.

[0075] In order to facilitate the placement of the first rotating shaft 1017, the top of the first support seat 1012 is provided with a first containing groove 10121, as shown in Figure 8 and Figure 9As shown. To limit the positioning of the first bearing bush 1019, a limiting groove 10122 for placing the first bearing bush 1019 is provided in the first receiving groove 10121. The bottom surface of the limiting groove 10122 is lower than the bottom surface of the first receiving groove 10121, and the limiting groove 10122 is arranged circumferentially around the first rotating shaft 1017. To prevent the shaft surface of the first rotating shaft 1017 from contacting the groove surface of the first receiving groove 10121, the surface of the first bearing bush 1019 used to support the first rotating shaft 1017 is set higher than the groove surface of the first receiving groove 10121. It can be understood that the top of the first support base 1012 is connected to the first shaft cover 1014, and the surface of the first shaft cover 1014 near the first rotating shaft 1017 is provided with the second bearing bush 10112. The top of the first support base 1012 is provided with a first threaded connection hole 10123, which is located on both sides of the first receiving groove 10121. The first connecting bolt 10110 passes through the connecting through hole on the first shaft cover 1014 and is threaded into the first threaded connection hole 10123. To improve connection reliability, multiple first threaded connection holes 10123 are provided. In one embodiment, four first threaded connection holes 10123 are provided, with two first threaded connection holes 10123 on each side of the first receiving groove 10121, such as... Figure 8 As shown.

[0076] To facilitate the support of the collector tube 4 of the trough solar collector, a first support assembly 1015 is provided on the top of the first end plate 1016 and the second end plate 1013. The bottom of the first support assembly 1015 is connected to the first end plate 1016 and the second end plate 1013, and the top is used to support the collector tube 4. In order to achieve reliable support for the collector tube 4, the support angle of the first support assembly 1015 is adjustable. Thus, when the collector tube 4 is not in a horizontal state, the first support assembly 1015 can still clamp the collector tube 4 by rotating a certain angle. The installation requirements for the collector tube 4 are low, which is conducive to installation.

[0077] Specifically, the first support assembly 1015 includes a first connecting plate 10152, a first support frame 10153, and a first support ring 10154, such as... Figure 10 As shown. The first connecting plate 10152 is fixedly connected to the top of the first end plate 1016 and the second end plate 1013, as follows. Figure 10As shown, one end of the first connecting plate 10152 is connected to the first end plate 1016, and the other end is connected to the second end plate 1013. The bottom of the first support frame 10153 is rotatably connected to the first connecting plate 10152 via the first support shaft 10151. To improve the reliability of the support, two first connecting plates 10152 are provided, and the two first connecting plates 10152 are set at a predetermined distance, which is set by those skilled in the art as needed. The two ends of the first support shaft 10151 are respectively connected to one of the first connecting plates 10152. The first support ring 10154 is rotatably connected to the top of the first support frame 10153 via the second support shaft 10155. The first support shaft 10151 can be a pin structure or a common shaft. The second support shaft 10155 can be arranged parallel to the first support shaft 10151, such as... Figure 10 As shown, the first support shaft 10151 and the second support shaft 10155 extend along the X-axis direction, and the first support frame 10153 extends along the Z-axis direction.

[0078] To facilitate the placement of the heat collector tube 4, the first support ring 10154 includes a first clamping ring 10154-2 and a second clamping ring 10154-1 that are configured to fit together, such as Figure 11 and Figure 12 As shown, both the first clamping ring 10154-2 and the second clamping ring 10154-1 have arc-shaped segments at the positions used to limit the heat collector tube 4. To facilitate the connection of the second support shaft 10155 and improve the stability of the support, the height of the arc-shaped segment of the first clamping ring 10154-2 is greater than the height of the arc-shaped segment of the second clamping ring 10154-1. There are two second support shafts 10155, one on each side of the first clamping ring 10154-2. One end of the second support shaft 10155 is fixedly connected to the first clamping ring 10154-2, and the other end is connected to the first support frame 10153 through an L-shaped connecting plate 10156. The first clamping ring 10154-2 and the second clamping ring 10154-1 are connected by a third connecting bolt 10154-3. The L-shaped connecting plate 10156 includes an L-shaped first plate and a second plate. The first plate is connected to the end of the second support shaft 10155 by a nut, and the second plate is connected to the first support frame 10153 by a fourth connecting bolt 10157. (Refer to...) Figure 11 and Figure 12 .

[0079] During installation, a first adjusting shim 10111 is provided between the first bearing housing and the first embedded steel plate 102. By adjusting the thickness of the first adjusting shim 10111 and the tightening force of the second connecting bolts 1018 at different positions, fine adjustments in height and horizontal plane are achieved to ensure installation accuracy. The first adjusting shim 10111 is made of high-polymer composite material and possesses pressure resistance, shock absorption, and corrosion resistance. The thickness of the first adjusting shim 10111 can be flexibly adjusted according to site conditions. Its deformation characteristics allow for fine-tuning of the height position of the first bearing housing, while adjusting the tightening force of the bolts ensures the flatness and accuracy of the first bearing housing. The first adjusting shim 10111 has sufficient thickness to ensure that it will not undergo significant plastic deformation under long-term loads, adapting to harsh environments.

[0080] To achieve dynamic adjustment of the flatness of the supporting column 1, auxiliary lugs 10113 are provided on both sides of the first connecting base plate 1011 of the first bearing seat, such as... Figure 5 and Figure 7 As shown, auxiliary ear plates 10113 are installed on both sides of the first bearing seat as counterweight hanging points. Dynamic balance adjustment of the support column 1 is achieved by suspending standardized counterweights (such as sandbags, metal weights, etc.). By suspending a preset load (determined according to wind load and installation environment), the auxiliary ear plates 10113 can quickly achieve dynamic adjustment of the flatness of the support column 1 on site, significantly reducing construction errors. The auxiliary ear plates 10113 are made of high-strength steel and welded to the first bearing seat.

[0081] Correspondingly, the second connecting body 201 includes a second bearing seat and a second rotating shaft 2015 rotatably connected to the second bearing seat. A third end plate 2018 and a fourth end plate 2019 are fixedly connected to the second rotating shaft 2015. At least one of the third end plate 2018 and the fourth end plate 2019 is connected to the main body of the trough solar collector. The second bearing seat is used to connect with the second embedded steel plate 202. To reduce the weight of the second rotating shaft 2015 while meeting heavy-duty requirements, the second rotating shaft 2015 is a hollow structure shaft, such as... Figure 15 As shown. Specifically, the third end plate 2018 and the fourth end plate 2019 are welded to both ends of the second rotating shaft 2015.
