Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support technology, and in particular to a photovoltaic support for salt ponds that prevents settling. Background Technology

[0002] Currently, the photovoltaic industry is actively exploring diverse application scenarios, and salt-solar hybrid photovoltaics, as an emerging development direction, is gradually becoming the focus of the industry. Floating photovoltaic power stations have attracted much attention due to their significant advantages, such as not occupying land resources and improving power generation efficiency. In this application model, the water body has a cooling effect on the photovoltaic modules, effectively absorbing the heat generated during operation, thereby enabling the modules to achieve higher power generation. Simultaneously, covering the solar panels on the water surface can significantly reduce water evaporation, contributing to water resource protection. It is worth mentioning that this method also has the effect of increasing production and improving the quality of shrimp farming in salt ponds, successfully realizing an ideal model of coordinated development and win-win for all parties, encompassing new energy power generation, salt pond aquaculture, and salt production.

[0003] Large-scale photovoltaic (PV) power plants typically consist of numerous unit arrays, which mainly include PV support structures and PV modules, with the PV modules being the core component. The support structure, as a stable support platform for the PV modules, shoulders multiple important responsibilities: firstly, it needs to effectively resist the erosion of its internal structure by salt; secondly, it must possess sufficient strength to withstand the loads transmitted from the surface of the PV modules under various operating conditions. Furthermore, it must meet the specified deformation requirements of the support structure to prevent additional stress on the PV modules due to deformation, thereby ensuring the normal operation of the PV modules installed on the support structure without any damage.

[0004] However, in the unique environment of salt lake waters, the foundation piles of photovoltaic array supports are highly susceptible to uneven settlement. This settlement generates secondary internal forces within the support platform structure. These secondary forces, combined with the original stresses in the structure, can have adverse effects. Mild settlement can lead to structural distortion; severe settlement can damage the support platform components. In such cases, microcracks may develop in the solar cells mounted on the platform, and in more serious situations, this can directly damage the photovoltaic modules, posing a significant threat to the safe and stable operation of the photovoltaic power station. To address these issues, we propose a settlement-resistant photovoltaic support system for salt lake waters. Utility Model Content

[0005] The main purpose of this invention is to provide a photovoltaic support structure for salt ponds that prevents sedimentation, in order to solve the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A photovoltaic support structure for preventing settlement in a salt pond includes an outer base column and an inner base column fixed coaxially. The outer base column has a plurality of anti-settlement spears movably mounted on its side wall. The anti-settlement spears penetrate the outer base column and the inner base column and extend into the interior of the inner base column. The inner base column has an outwardly pushing member that drives the tip of the anti-settlement spear to protrude out of the outer base column. A sealing member is also provided between the anti-settlement spear and the outer base column. A concrete layer is also formed between the outer base column and the inner base column.

[0007] As a further improvement of this utility model, the pusher includes a top that is slidably connected to the inner wall of the inner base column, a pressure plate is movably provided directly below the top column, and the bottom of the pressure plate is hinged with hinge rods that are respectively hinged to a plurality of anti-settlement spears.

[0008] As a further improvement of this utility model, the inner base column is internally fixed with several guide rails, the anti-settlement spear is slidably connected to the several guide rails one by one, and a reinforcing rod is fixed between the inner base column and the bottom wall of the guide rails.

[0009] As a further improvement of this utility model, the outer wall of the outer base column is provided with a rotating cylinder, the top of which extends to the top of the outer base column and is threadedly connected to the top column.

[0010] As a further improvement of this utility model, the sealing element includes a first sealing groove disposed on the outer wall of the outer base column. The first sealing groove is disposed on the outer periphery of the penetration point between the anti-settlement spear and the outer base column. A first salt-resistant sealing gasket is provided at the bottom of the first sealing groove. A first sealing plate composed of several fan-shaped baffles is fixedly connected to the tip of the anti-settlement spear. The ends of the several fan-shaped baffles near the center are all fixedly connected.

[0011] As a further improvement of this utility model, a guide plate is fixedly connected to the inner wall of the inner base column, and a guide rod is connected to the output end of the pusher. The guide rod passes through the guide plate and is slidably connected to it, and an elastic element is provided on the outer wall of the guide rod.

[0012] As a further improvement of this utility model, the inner wall of the outer base column is provided with a second sealing groove corresponding to the first sealing groove, the bottom of the second sealing groove is provided with a second salt-resistant sealing gasket, and the outer wall of the anti-settlement spear is fixedly sleeved with a second sealing plate that is inserted and matched with the second sealing groove.

[0013] As a further improvement of this utility model, the top of the rotating cylinder is provided with a grouting port that connects the concrete layer with the outside, and the top of the rotating cylinder is also slidably provided with a sliding cover for opening and closing the grouting port.

[0014] This invention incorporates an outward-pushing component and an anti-settlement spear. The anti-settlement spear is circumferentially positioned on the side wall of the outer base column. When the support is driven into the bottom of the salt pond, the outward-pushing component drives the tip of the anti-settlement spear to insert into the surrounding soil. This arrangement allows the anti-settlement spear to support and anchor the support from multiple directions, enhancing the friction and interlocking force between the support and the surrounding soil, greatly improving the support's ability to resist settlement, and solving the problem of easy settlement of the support under the complex geological conditions of the salt pond.

[0015] A sealing element is installed between the anti-settlement spear and the outer base column, employing a double-sealing design. The cooperation of the first sealing plate and the first salt-resistant sealing gasket, and the second sealing plate and the second salt-resistant sealing gasket, effectively prevents water and corrosive substances in the salt pond from penetrating the internal structure of the support. Simultaneously, the sealing gasket is made of highly corrosion-resistant materials, further enhancing the durability of the support in the highly corrosive environment of the salt pond.

[0016] A concrete layer is formed between the outer and inner base columns, and high sulfate-resistant cement concrete is poured inside, which enhances the overall structural integrity between the two and improves the protection against the external environment. The top of the rotating cylinder is equipped with a grouting port and a sliding cover, which facilitates the pouring of the concrete layer and prevents debris and moisture from entering and affecting the concrete performance and the integrity of the support structure, further improving the long-term stability of the photovoltaic support in the salt pond environment.

[0018] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0019] Please see Figure 1-6 This embodiment provides an example of a photovoltaic support structure for preventing settlement in a salt pond. In this embodiment, the photovoltaic support structure includes an outer base column 1 and an inner base column 2 that are coaxially fixed. The bottom of the inner base column 2 is fixed to the inner wall of the outer base column 1 through a fixing seat. Several ribs are also fixed between the outer base column 1 and the inner base column 2 to strengthen the strength of the inner and outer base columns. The design of the outer base column 1 and the inner base column 2 is optimized based on the complex geological conditions of the salt pond water area, aiming to improve the overall stability and load-bearing capacity of the support structure.

[0020] The outer base column 1 is circumferentially equipped with several anti-settlement spears 3. These anti-settlement spears 3 penetrate the outer base column 1 and the inner base column 2 and extend into the interior of the inner base column 2. The inner base column 2 is equipped with an outward-pushing member 4 for driving the tips of the anti-settlement spears 3 out of the outer base column 1. When the support is driven into the bottom of the salt pond, the outward-pushing member 4 gradually pushes the tips of the anti-settlement spears 3 outward from the outer base column 1, causing them to insert into the surrounding soil. These anti-settlement spears 3 enhance the friction and interlocking force between the support and the surrounding soil, acting like strong "anchor nails," greatly improving the support's ability to resist settlement.

[0021] To prevent water and corrosive substances in the salt pond from seeping into the internal structure of the support structure through the gap between the anti-settlement spear 3 and the outer base column 1, a sealing element 5 is also provided between the anti-settlement spear 3 and the outer base column 1. The sealing element 5 is made of a highly corrosion-resistant material, which not only effectively prevents the penetration of water and salt substances, but also maintains good sealing performance under external force, ensuring that the internal structure of the inner base column 2 and the outer base column 1 is not corroded, thus extending the service life of the support structure.

[0022] A concrete layer 6 is formed between the outer base column 1 and the inner base column 2. The concrete layer 6 not only enhances the structural integrity between the outer base column 1 and the inner base column 2, enabling them to jointly withstand external forces, but also further fills the gap between them, improving their ability to protect against the external environment.

[0023] Preferably, the concrete layer 6 is filled with high sulfate-resistant cement concrete. High sulfate-resistant cement concrete can significantly improve the durability of concrete in the salt pond environment, reduce the risk of structural damage and failure, and its internal structure is more compact, with better salt erosion resistance than ordinary Portland cement.

[0024] Furthermore, the pusher 4 includes a top column 41 that is slidably connected to the inner wall of the inner base column 2. A pressure plate 42 is movably provided directly below the top column 41. When the top column 41 moves downward, the pressure plate 42 will follow its movement and gradually press downward. The bottom of the pressure plate 42 is hinged with hinge rods 43 that are respectively hinged to several anti-settlement spears 3.

[0025] The hinge rods 43 convert the movement of the pressure plate 42 into the extension of the anti-settlement spears 3. One end of each hinge rod 43 is hinged to the bottom of the pressure plate 42, and the other end is hinged to the corresponding anti-settlement spear 3, forming a linked mechanical structure. This hinge structure can effectively convert the axial pressure on the pressure plate 42 into the outward thrust of the anti-settlement spear 3.

[0026] When the top column 41 moves downward under the action of external driving force, the pressure plate 42 also moves downward under the push of the top column 41. At this time, the pressure plate 42 applies an outward pushing force to each anti-settlement spear 3 through the hinge rod 43, so that the tip of the anti-settlement spear 3 can gradually protrude out of the outer base column 1 and insert into the surrounding soil, thereby realizing the function of enhancing the friction and interlocking force between the support and the soil and resisting settlement.

[0027] Furthermore, several guide rails 44 are fixedly connected inside the inner base column 2, and each anti-settlement spear 3 is slidably connected to the corresponding guide rail 44. A reinforcing rod 45 is fixedly connected between the inner base column 2 and the bottom wall of the guide rail 44. The design of the guide rail 44 and the reinforcing rod 45 can effectively offset the vertical downward force on the anti-settlement spear 3 when the top column 41 presses down on the pressure plate 42, thus protecting the anti-settlement spear 3.

[0028] The reinforcing rod 45 shares the lateral force and stress applied to the guide rail 44 during the sliding process of the anti-settlement spear 3, ensuring that the guide rail 44 always maintains its proper position and state, thereby effectively ensuring that the anti-settlement spear 3 can move according to the design requirements.

[0029] Furthermore, the outer wall of the outer base column 1 is provided with a rotating cylinder 7, which is connected to the outer wall of the outer base column 1 by a sliding friction device, thereby ensuring that the rotating cylinder 7 can rotate around the central axis of the outer base column 1.

[0030] The top of the rotating cylinder 7 extends to the top of the outer base column 1 and is threadedly connected to the top column 41. On the outer wall of the top column 41, at least one longitudinal guide groove is machined in the axial direction. The shape of the guide groove can be a dovetail groove, a T-shaped groove, or a rectangular groove.

[0031] Meanwhile, on the inner wall of the inner base column 2, corresponding to the position of the guide groove, a matching slider is fixedly connected. The shape of the slider should perfectly match the shape of the guide groove.

[0032] When the rotating cylinder 7 is rotated, the top column 41 is driven to move up and down linearly via the threaded transmission. The guide groove on the top column 41 slides along the slider. Since the guide groove restricts the slider to move only in the axial direction (i.e., the vertical direction), it effectively constrains the rotational freedom of the top column 41, so that the top column 41 can only move linearly in the vertical direction and cannot rotate with the rotating cylinder 7. This ensures the stability and accuracy of the movement of the top column 41, thereby ensuring that the actions of the pressure plate 42 and the anti-settlement spear 3 driven by the top column 41 can be performed as expected.

[0033] Furthermore, the sealing element 5 includes a first sealing groove 51 disposed on the outer wall of the outer base column 1. The first sealing groove 51 is disposed on the outer periphery of the penetration point between the anti-settlement spear 3 and the outer base column 1, and can surround the connection between the anti-settlement spear 3 and the outer base column 1 in all directions, providing a first protective barrier for any possible gaps.

[0034] A first salt-resistant sealing gasket 52 is provided at the bottom of the first sealing groove 51. It is made of a highly corrosion-resistant material specifically developed for the highly corrosive environment of salt ponds, capable of resisting the erosion of high-concentration salt in the salt pond water for a long time. The tip of the anti-settlement spear 3 is fixedly connected to a first sealing plate 53 composed of several fan-shaped baffles. Each fan-shaped baffle is fixed at its end near the center. When the support is driven into the bottom of the salt pond, the cooperation between the first sealing plate 53 and the first salt-resistant sealing gasket 52 prevents water and corrosive substances in the salt pond from entering the internal structure of the support through the gap between the anti-settlement spear 3 and the outer base column 1. As the tip of the anti-settlement spear 3 is gradually pushed outwards from the outer base column 1, the tip of the anti-settlement spear 3 will drive the first sealing plate 53 to move. With the soil blocking the first sealing plate 53, each of the spliced ​​fan-shaped baffles will move towards the anti-settlement spear 3 and tightly wrap around its tip. This splicing design prevents the anti-settlement spear 3 from obstructing its penetration into the soil.

[0035] It should be noted that the design of the dimensions of the first sealing groove 51 should fully consider the structural dimensions of the entire photovoltaic support and the corrosive effects of the salt pool environment. It should ensure that it can accommodate the sealing components to be installed later, but should not weaken the structural strength of the external base column 1 too much.

[0036] Furthermore, a guide plate 8 is fixedly connected to the inner wall of the inner base column 2, and a guide rod 9 is connected to the output end of the outer pusher 4. The guide rod 9 passes through the guide plate 8 and is slidably connected to it. An elastic element 10 is provided on the outer wall of the guide rod 9. The elastic element 10 is a compression spring. The spring is set between the guide plate 8 and the pressure plate 42. Through the elastic element 10, when the support is driven into the bottom of the salt pool, the elastic element 10 provides an upward force to the pressure plate 42, so that the pressure plate 42 drives the anti-settlement spear 3 to retract into the support through the hinge rod. This allows the first sealing plate 53 to be tightly pressed on the first salt-resistant sealing gasket 52, preventing water and corrosive substances in the salt pool from entering the internal structure of the support through the gap between the anti-settlement spear 3 and the outer base column 1.

[0037] Furthermore, a second sealing groove 54 is provided on the inner wall of the outer base column 1 corresponding to the first sealing groove 51. A second salt-resistant sealing gasket 55 is provided at the bottom of the second sealing groove 54. A second sealing plate 56 is fixedly sleeved on the outer wall of the anti-settlement spear 3, which is inserted into the second sealing groove 54. After the anti-settlement spear 3 protrudes from the outer base column 1 and inserts into the soil, the second sealing plate 56 can be accurately inserted into the second sealing groove 54. Due to the presence of the second salt-resistant sealing gasket 55, a good sealing contact is formed between the two, effectively preventing liquid in the salt pond from seeping into the support through the gap between the inner wall of the anti-settlement spear 3 and the outer base column 1. This significantly enhances the photovoltaic support's resistance to water and corrosive substances, further improving the long-term stability and reliability of the entire device in the salt pond environment.

[0038] Preferably, the first salt-resistant gasket 52 and the second salt-resistant gasket 55 can be chlorosulfonated polyethylene synthetic rubber, which has good corrosion resistance to acid, alkali and salt solutions, and is unaffected by climate, light, ozone and commercial fuels (such as diesel and kerosene).

[0039] Furthermore, the top of the rotating cylinder 7 is equipped with a grouting port 11 that connects the concrete layer 6 to the outside. This is a key channel for injecting concrete material into the concrete layer 6. The top of the rotating cylinder 7 also has a sliding cover 12 for opening and closing the grouting port 11. When construction personnel need to perform grouting operations on the concrete layer 6, they can simply slide the sliding cover 12 to open it, exposing the grouting port 11, allowing concrete to be smoothly injected into the concrete layer 6 through the grouting port 11. After grouting is completed, the sliding cover 12 is slid to the closed position to tightly seal the grouting port 11. This design not only effectively prevents external debris and moisture from entering the concrete layer 6 and adversely affecting the curing and performance of the concrete, but also ensures the integrity and sealing of the internal structure of the rotating cylinder 7 during long-term use of the photovoltaic support, further improving the stability and durability of the entire photovoltaic support in the salt pond environment. The sliding relationship between the sliding cover 12 and the top of the rotating cylinder 7 is existing technology and will not be elaborated here.

[0040] The specific embodiments of the utility model have been described in detail above, but they are only examples, and the utility model is not limited to the specific embodiments described above. For those skilled in the art, any equivalent modifications or substitutions to the utility model are also within the scope of the utility model. Therefore, all equivalent transformations, modifications, and improvements made without departing from the spirit and principles of the utility model should be covered within the scope of the utility model.
