Description

Technical Field

[0001] This utility model relates to the field of solar heating technology, and in particular to an explosion-proof heat collection pipe component and a solar heat collection system. Background Technology

[0002] A solar collector is a device that converts solar radiation into heat energy; its main structure is as follows: Figure 1 and Figure 2 As shown.

[0003] Considering the long hours of sunshine on sunny days, the temperature of the heat exchange medium (antifreeze is often chosen for heating) inside the vacuum collector tubes will be high during long-term operation in such environments. However, in such conditions, there is often no need for long-term heat collection and heating. Therefore, after prolonged heating, the temperature of the medium inside the tubes / manifolds will be too high, which may easily lead to damage to the heat collection system.

[0004] In the existing technology, a component is used to shield the heat collection tube to prevent the medium inside the heat collection tube from overheating. However, the above structure is too complicated and will significantly change the structure of the original heat collection system, which will undoubtedly greatly increase the cost.

[0005] Therefore, further improvements are needed. Utility Model Content

[0006] This utility model aims to at least partially solve one of the technical problems in related technologies. Therefore, one objective of this utility model is to provide a heat collection tube explosion-proof component that uses a transmission method to drive the plate to rotate for light blocking, with a simple structure that essentially does not alter the original heat collection system structure.

[0007] Another objective of this invention is to provide a solar thermal system comprising the aforementioned explosion-proof collector tube components.

[0008] The technical solution of this utility model is as follows:

[0009] A heat collector tube explosion-proof assembly, comprising:

[0010] A rotating component is configured on the outer periphery of the heat collection tube and can rotate around the outer wall of the heat collection tube. Adjacent rotating components are driven and coordinated.

[0011] The plate is mounted on the rotating assembly;

[0012] And a driving component for driving at least one rotating component to rotate.

[0013] Based on the above technical solution, it is easy to switch the light-collecting and light-shading modes of the heat collection tube. The structure is simple and basically does not require any changes to the structure of the heat collection system.

[0014] Furthermore, the rotating assembly includes a positioning ring and a driving ring sleeved on the outside of the heat collection tube. The positioning ring and the driving ring are fitted with the heat collection tube with a clearance, so that they can be easily assembled on the heat collection tube and can rotate around the heat collection tube. Adjacent driving rings are in transmission engagement, and the plate is installed on the outer edge of the positioning ring and the driving ring.

[0015] Based on the above technical solution, the rotating component is based on a two-ring structure with plates, which is simple in structure and can also greatly reduce the weight of the component and reduce the impact of the component on the heat collection tube.

[0016] Furthermore, the drive ring has a gear formed on its outer edge, which meshes with the gear in the adjacent drive ring for transmission.

[0017] Furthermore, the rotating assembly also includes a positioning drag for positioning the drive ring.

[0018] Furthermore, the positioning bracket is made of rubber sleeve material and is interference-fitted onto the tail end of the heat collection tube; and / or, the positioning bracket is formed by extending the end of the tail bracket axially toward the drive ring.

[0019] Furthermore, the top of the drive ring is provided with an assembly part; and / or, the bottom of the drive ring is provided with a support part.

[0020] Based on the above technical solution, the installation and matching positions of the relevant structures can be guaranteed, and the structure is simple.

[0021] Furthermore, the positioning ring and drive ring are made of plastic.

[0022] Furthermore, the sheet metal is designed to be curved.

[0023] Furthermore, the thickness is 0.5-3mm.

[0024] Furthermore, the central angle corresponding to the arc of the arc-shaped plate section is 45°-210°; more preferably 75°-180°.

[0025] Based on the above technical solutions, the overall weight of the components is further reduced, and the assembly, bending and winding of the panels are also easier, ensuring the area of ​​shading without affecting normal lighting.

[0026] Furthermore, the side of the plate closest to the heat collection tube can also be made reflective.

[0027] Based on the above technical solution, it is easier to better concentrate reflected light and heat the heat collection tube when needed.

[0028] Furthermore, the drive assembly includes at least one set of power units, the output of which is connected to the drive ring drive.

[0029] A solar thermal collector system includes the aforementioned explosion-proof collector tube assembly. Attached Figure Description

[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0043] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0044] Reference Figure 3-5 Some embodiments of this application disclose an explosion-proof assembly for a heat collection tube, including a rotating assembly disposed on the outer periphery of the heat collection tube 14, which can rotate around the outer wall of the heat collection tube 14, and adjacent rotating assemblies are driven together; wherein, the rotating assembly includes a plate 23, and when the rotating assembly rotates around the corresponding heat collection tube 14 after being driven by the driving assembly 3, the plate 23 rotates basically around the axis of the corresponding heat collection tube 14, and adjacent plates 23 do not interfere with each other during rotation.

[0045] like Figure 3 and Figure 4 As shown, the rotating assembly includes a positioning ring 21 and a driving ring 22 sleeved on the outside of the heat collection tube 14. The positioning ring 21 and the driving ring 22 are fitted with the heat collection tube 14 with a clearance, so that they can be easily assembled on the heat collection tube and can rotate around the heat collection tube 14. The adjacent driving rings 22 are in transmission engagement, and the plate 23 is installed on the outer edge of the positioning ring 21 and the driving ring 22. Preferably, the positioning ring 21 and the driving ring 22 are made of plastic, which can significantly reduce the overall weight.

[0046] In some embodiments, plate 23 is designed in an arc shape. It can be made of metal sheet such as aluminum, with a thickness of approximately 0.5-3mm, which is easy to bend into an arc shape. Other sheets that are easy to assemble and bend can also be chosen. During installation, plate 23 can be directly fixed to drive ring 21 and drive ring 22 using fasteners (such as screws). Other conventional fixing methods are also acceptable, and this embodiment does not impose specific limitations. Considering the area of ​​light shading and without affecting normal lighting, the central angle corresponding to the arc of the plate's cross-section is preferably 45°-210°, more preferably 75°-180°. The side of plate 23 closest to the heat collector tube 14 can also be designed as a reflective surface to better concentrate and reflect light for heating the heat collector tube when needed.

[0047] like Figure 4 and Figure 5 The drive ring 22 has a gear 221 formed on its outer surface, which meshes with the adjacent drive ring for transmission. The drive ring 22 is positioned by the positioning bracket 24 to ensure its installation position and facilitate the subsequent engagement of adjacent drive rings. In some embodiments, the positioning bracket 24 is made of rubber sleeve material and is interference-fitted onto the tail end of the heat collector tube 14. Of course, the positioning bracket 24 can also be formed by extending the end of the tail bracket 15 axially toward the drive ring 22. The dimensions of the positioning ring 21 and the drive ring 22 are reasonably set based on the outer diameter of the heat collector tube and the installation spacing of the heat collector tube, so that the positioning ring 21 and the drive ring 22 can rotate freely around the outside of the heat collector tube, while the adjacent gears 221 can mesh for transmission.

[0048] In addition, considering the assembly of the plate 23, the top of the drive ring 22 is provided with an assembly part 222 to facilitate the subsequent fixing of the plate 23; at the same time, the bottom of the drive ring 22 is provided with a support part 223 to facilitate the interference between the gear 221 and the positioning bracket 24 during the rotation of the drive ring 22.

[0049] like Figure 6 and Figure 7 The drive assembly 3 includes a motor 31, and a drive gear 32 is fixed on the drive shaft of the motor 31. The drive gear 32 meshes with the gear 221 to transmit power. At this time, the motor 31 is fixed on the tail support bracket 13 through an L-shaped motor bracket 33.

[0050] Of course, the drive ring can also be driven to rotate by means such as chain drive or belt drive. In this case, it is only necessary to form a corresponding gear or transmission wheel at the corresponding position of the drive ring 22 in the axial direction of the corresponding drive gear 32.

[0051] The drive assembly 3 can be set to a single set, or multiple sets can be set according to the number of heat collection tubes, and synchronously driven to ensure sufficient output power to drive all drive rings 22 to rotate. Since the drive rings 22 are matched, when multiple sets of motors drive the corresponding gears 221, they should maintain a matching rotation direction; at the same time, the rotation angle of the plate depends on the installation position and requirements. For example, if the initial position of the plate 23 is set on the back side of the heat collection tube, the plate 23 can be rotated 180° by the motor to achieve the switching between shading and heating modes.

[0052] A solar thermal collection system, such as Figure 3-7 This includes the aforementioned explosion-proof components for the heat collection pipes.

[0053] The heat collection system 1 includes a mounting frame 11, a manifold 12 is installed on the top of the mounting frame 11, and a tail support 15 is installed at the bottom of the mounting frame 11 via a tail support bracket 13. The heat collection pipe 14 is installed in the corresponding mounting holes of the tail support 15 and the manifold 12. The explosion-proof component is fitted into the heat collection pipe 14 before installation, and the position of the drive ring 22 is adjusted by the positioning drag 24 to keep the adjacent drive rings engaged.

[0054] In this application, the structures and connections not described in detail are all prior art, and their structures and principles are well known, so they will not be described in detail here.
