Description

Technical Field

[0001] This invention belongs to the field of heliostat technology, and particularly relates to an interactive heliostat connection device. Background Technology

[0002] With the rapid development of economy and technology, energy demand is increasing daily, and the consumption of non-renewable energy is also gradually increasing. People are seeking more renewable energy alternatives. Solar energy, as a clean and renewable energy source, is being developed and utilized more and more. Initially, solar power generation was mainly photovoltaic power generation. However, with the development of science and technology, especially the rise of computer control technology, solar thermal power generation, an emerging solar energy utilization technology, has also received much attention.

[0003] Solar thermal power generation uses numerous reflectors to focus the energy of direct sunlight, heating a working fluid to produce high-temperature, high-pressure steam, which then drives a turbine to generate electricity. The main structure of the heliostat (including columns, corner drive devices, and mirror frames) is fixed to the ground, serving as the supporting structure for the reflectors. Its structural safety is crucial for the normal operation of the entire heliostat field.

[0004] Solar thermal power generation projects are typically located in harsh environments with strong winds and sandstorms, and the working load of heliostats is mainly wind load. Therefore, the wind resistance design of the heliostat structure is crucial. Currently, this is mainly divided into two aspects: the wind resistance design of the enclosure structure and the wind resistance design of the main structure. The enclosure structure mainly refers to wind-resistant barriers, such as windbreaks. However, in structural engineering, the wind resistance design of the main structure is of greater concern. Therefore, improving safety performance and enhancing wind resistance are principles that designers must carefully consider when designing structural schemes. Summary of the Invention

[0005] The purpose of this invention is to provide an interactive heliostat connection device to enhance the wind resistance of the heliostat main structure.

[0006] The technical solution of this invention is as follows:

[0007] An interchangeable heliostat connection device is disposed between two adjacent heliostats, and the main beam end of the heliostat has an axially arranged shaft hole. The interchangeable heliostat connection device includes two connecting components, which are respectively disposed at the ends of the main beams of the two adjacent heliostats that are close to each other. The connecting components include:

[0008] The main beam extension is slidably connected to the shaft hole of the corresponding main beam;

[0009] The main beam telescopic mechanism has a fixed end connected to the main beam and a telescopic end connected to the main beam extension, which is used to drive the main beam extension to slide.

[0010] At least two secondary beam telescopic mechanisms, wherein the fixed end and telescopic end of the secondary beam telescopic mechanism are respectively connected to the secondary beam of the corresponding heliostat and the extension of the main beam, and the portion of the secondary beam located on both sides of the main beam is respectively connected to at least one of the secondary beam telescopic mechanisms;

[0011] In use, the main beam extensions of the two connecting components extend and connect.

[0012] In one embodiment of the interactive heliostat connection device, one of the main beam extensions in the two connection components is provided with a buckle and the other is provided with a buckle seat. In use, the buckle is inserted into the buckle seat to engage, thereby realizing the docking of the two main beam extensions in the two connection components.

[0013] In one embodiment of the interactive heliostat connection device, among the main beam extensions of the two connection components, at least one of the main beam extensions has a sleeve at one end near the other main beam extension; in use, the two main beam extensions of the two connection components are nested together to achieve docking.

[0014] In one embodiment of the interactive heliostat connection device, the main beam extension is a sleeve, and the sleeves in the two connection components have different apertures. In use, the two sleeves in the two connection components are nested together to achieve docking.

[0015] In one embodiment of the interactive heliostat connection device, the connection assembly further includes a sleeve connection plate, which is fixed to the sleeve and located at one end of the sleeve near the sleeve in another connection assembly. The main beam telescopic mechanism and the secondary beam telescopic mechanism are both connected to the sleeve connection plate to achieve connection with the sleeve.

[0016] In one embodiment of the interactive heliostat connection device, the connection assembly further includes a sleeve connection plate, which is fixed to the sleeve and disposed at one end of the sleeve near the sleeve in another connection assembly;

[0017] Each of the two connecting components has a buckle and a buckle seat connected to its sleeve connecting plate. When the two sleeves are nested together, the buckle is inserted into the buckle seat to achieve a snap-fit.

[0018] In one embodiment of the interactive heliostat connection device, in use, each of the sub-beam telescopic mechanisms and the corresponding main beam extension and sub-beam form a triangular configuration, and the fixed end and telescopic end of the sub-beam telescopic mechanism are respectively movably connected to the corresponding sub-beam and the main beam extension.

[0019] In one embodiment, an interactive heliostat connection device includes two secondary beam telescopic mechanisms, which are symmetrically arranged about the main beam and connected to the secondary beams closest to both ends of the main beam.

[0020] In one embodiment of the interactive heliostat connection device, the connection component further includes a mounting base, the mounting base is mounted on a corresponding main beam, and the fixed end of the main beam telescopic mechanism is fixedly connected to the mounting base.

[0021] In one embodiment of the interactive heliostat connection device, in the same connection component, at least one of the main beam telescopic mechanism and the plurality of secondary beam telescopic mechanisms is an electric telescopic mechanism.

[0022] Because the present invention adopts the above technical solution, it has the following advantages and positive effects compared with the prior art:

[0023] The interactive heliostat connection device provided by this invention has two connection components installed on the main beam and secondary beam of two adjacent heliostats, respectively. When the ambient wind speed is high, the telescopic ends of the main beam telescopic mechanism and the secondary beam telescopic mechanism in both connection components extend, driving the main beam extension to extend. After extending to a certain extent, the two main beam extensions dock, connecting the main beams of the two adjacent heliostats. Meanwhile, the secondary beam telescopic mechanism is in an extended state, connected with the secondary beam and the main beam extension, forming a support net with the main beam extension, thereby enhancing the wind resistance of the heliostat's main structure and improving the safety of the heliostat.

[0024] Meanwhile, the interactive heliostat connection device provided by this invention is installed on the heliostats in the field of mirrors. When the ambient wind speed is high, the adjacent heliostats are connected in pairs to increase the support structure (that is, this device), enhance the wind resistance of the heliostats, and improve the structural stability and safety of the overall mirror field.

[0025] When the ambient wind speed decreases to a lower level, the telescopic ends of the main beam telescopic mechanism and the secondary beam telescopic mechanism retract, causing the main beam extension to retract into the shaft hole of the heliostat main beam. This also increases the main beam stiffness of a single heliostat to some extent, which is beneficial to the safe operation of the structure. Attached Figure Description

[0033] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of the present invention. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0034] To keep the drawings concise, only the parts relevant to the invention are shown schematically in each figure, and they do not represent the actual structure of the product. Furthermore, for ease of understanding, in some figures, only one of components with the same structure or function is shown schematically, or only one is labeled. In this document, "one" can mean not only "only one" but also "more than one".

[0035] See Figures 1 to 4 This embodiment provides an interactive heliostat connection device, disposed between two adjacent heliostats. The axes of the main beams 8 of these two adjacent heliostats are located on the same straight line, or the two axes are not on the same straight line but are approximately offset from each other. Furthermore, both ends of the heliostat main beams 8 have axially arranged shaft holes.

[0036] The interactive heliostat connection device includes two connection components, which are respectively located at the ends of the main beams 8 of two adjacent heliostats that are close to each other.

[0037] The connecting assembly includes a main beam extension, a main beam telescopic mechanism 3, and at least two secondary beam telescopic mechanisms 5. The main beam extension is slidably connected to the shaft hole of the corresponding main beam 8. Typically, this shaft hole extends through the entire axial direction of the main beam 8, meaning the main beam 8 is a tubular structure, referred to as the main beam tube, and thus the main beam extension is slidably connected within the main beam tube. The fixed end of the main beam telescopic mechanism 3 is connected to the main beam 8, and the telescopic end is connected to the main beam extension, used to drive the main beam extension to slide. The fixed end and telescopic end of the secondary beam telescopic mechanism 5 are respectively connected to the secondary beam 9 of the corresponding heliostat and the main beam extension, and the portion of the secondary beam 9 located on both sides of the main beam 8 is connected to at least one secondary beam telescopic mechanism 5. In use, the main beam extensions in the two connecting assemblies extend and dock.

[0038] Specifically, the main beam extension is a sleeve 1. The sleeves 1 in the two connecting components have different bore diameters. In use, the two sleeves 1 in the two connecting components are nested together to achieve docking. A sliding bearing can be used to connect the sleeve 1 and the main beam tube. By selecting a suitable bearing, the coaxiality of the main beam tube and the sleeve 1 is ensured, thereby guaranteeing the smooth nesting of the two sleeves 1 in the two connecting components. Of course, in other embodiments, other methods can also be used to ensure smooth nesting of the two sleeves 1 in the two connecting components. A sleeve connecting plate 2 is fixedly connected to the sleeve 1, such as... Figure 3 and Figure 4 As shown, the sleeve connecting plate 2 is located at one end of the sleeve 1 near the sleeve 1 in another connecting assembly. The telescopic ends of the main beam telescopic mechanism 3 and the secondary beam telescopic mechanism 5 are both connected to the sleeve connecting plate 2, thereby achieving connection with the sleeve 1. A buckle 6 and a buckle seat 7 are respectively connected to the sleeve connecting plate 2 in the two connecting assemblies. When the two sleeves 1 are nested and connected in place, the buckle 6 inserts into the buckle seat 7 to achieve a locking action, thereby enhancing the connection strength of the two sleeves 1.

[0039] In other embodiments, the docking method of the main beam extensions in the two connecting components can also be other, and there are no specific limitations. For example, in one embodiment, the main beam extension does not need to be a sleeve 1. In the main beam extensions of the two connecting components, one is provided with a buckle 6 and the other with a buckle seat 7. In use, the buckle 6 is inserted into the buckle seat 7 to engage, thereby achieving docking of the two main beam extensions in the two connecting components. In another embodiment, the two main beam extensions in the two connecting components do not need to both be sleeves 1. As long as one main beam extension has a sleeve 1 at the end closest to the other main beam extension, the two main beam extensions can be nested and connected in use, thus achieving docking.

[0040] The connecting assembly includes two secondary beam telescopic mechanisms 5, which are symmetrically arranged about the main beam 8, and each secondary beam telescopic mechanism 5 is connected to the secondary beam 9 closest to both ends of the main beam 8. In use, each secondary beam telescopic mechanism 5, its corresponding sleeve 1, and secondary beam 9 form a triangular configuration, which provides better stability. Of course, in other embodiments, the connecting assembly may include more secondary beam telescopic mechanisms 5, and the secondary beam telescopic mechanisms 5 may also be connected to secondary beams 9 that are not closest to both ends of the main beam 8 (in which case, special care should be taken to avoid interference with the original structure of the heliostat when setting the secondary beam telescopic mechanisms 5), and there is no limitation in this regard.

[0041] A sub-beam connecting plate can be welded onto the sub-beam 9 to facilitate the connection of the sub-beam telescopic mechanism 5. The fixed end and telescopic end of the sub-beam telescopic mechanism 5 are respectively movably connected to the corresponding sub-beam connecting plate and sleeve connecting plate 2, specifically through a fisheye bearing; however, this is not limited here, for example, in other embodiments, a hinged connection can be used.

[0042] An mounting base is installed on the main beam 8, and the fixed end of the main beam telescopic mechanism 3 is fixedly connected to the mounting base. Specifically, the mounting base is a hanger 4, which suspends the fixed end of the main beam telescopic mechanism 3 below the main beam 8. In other embodiments, the mounting base can adopt other structures, such as a mounting plate welded to the main beam 8, with the fixed end of the main beam telescopic mechanism 3 fixedly connected to the mounting plate by fasteners or other means; or the mounting base can also be a clamp that holds the fixed end of the main beam telescopic mechanism 3, with the clamp fixedly connected to the main beam 8, and so on.

[0043] In the same connecting assembly, at least one of the main beam telescopic mechanism 3 and several secondary beam telescopic mechanisms 5 is an electric telescopic mechanism, used to realize the automatic extension and retraction of the sleeve 1 within the main beam tube. Specifically, in this embodiment, the main beam telescopic mechanism 3 is an electric push rod. However, in other embodiments, the secondary beam telescopic mechanisms 5 may be electric telescopic mechanisms, or both the main beam telescopic mechanism 3 and all secondary beam telescopic mechanisms 5 may be electric telescopic mechanisms; there is no limitation here. Furthermore, other electric telescopic mechanisms may also be used in other embodiments, such as cylinders with electronic control functions.

[0044] It should be noted that both the main beam telescopic mechanism 3 and the secondary beam telescopic mechanism 5 include two structures that can move relative to each other. In this article, the fixed end refers to the one of these two mutually movable structures that is connected to the main beam 8 or the secondary beam 9, while the telescopic end refers to the one that is connected to other mechanisms.

[0045] The working process of the interactive heliostat connection device provided in this embodiment is as follows: When the wind speed is high, the telescopic mechanism 3 of the main beam in both connection components drives its telescopic end to extend and pushes the sleeve connecting plate 2 to move towards the other sleeve connecting plate 2, so that the two sleeves 1 move towards each other until the buckle 6 touches the buckle seat 7 and the two are engaged. The two sleeves 1 are also partially engaged and locked together, connecting the two heliostats together, enhancing the wind resistance of the main structure of the heliostat and improving safety. When the wind speed decreases, the telescopic ends of the two main beam telescopic mechanisms 3 retract respectively, the buckle 6 disengages from the buckle seat 7, the two sleeves 1 separate, and the connection between the two adjacent heliostats is also broken.

[0046] The interactive heliostat connection device provided in this embodiment not only enhances the wind resistance of the main heliostat structure and improves the structural stability and safety of the overall heliostat field, but also, when the ambient wind speed decreases to a lower level, the telescopic ends of the main beam telescopic mechanism 3 and the secondary beam telescopic mechanism 5 retract, causing most of the sleeve 1 to retract into the main beam tube of the heliostat. This also increases the stiffness of the main beam 8 of a single heliostat to a certain extent, which is beneficial to the safe operation of the structure. Furthermore, this embodiment has a simple design, is easy to install and maintain, and is easy to disassemble.

[0047] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments. Even if various changes are made to the present invention, if these changes fall within the scope of the claims of the present invention and their equivalents, they shall still fall within the protection scope of the present invention.
