Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power station equipment technology, specifically a mobile photovoltaic power station. Background Technology

[0002] The oilfield is located in a transitional zone between the northern subtropical and warm temperate zones, characterized by a northern subtropical monsoon continental climate with distinct monsoon advances and retreats and the alternation of seasons, resulting in a mild climate. The oilfield's vast operating area boasts abundant solar energy resources, making photovoltaic (PV) power generation a uniquely advantageous method for effectively reducing carbon dioxide emissions. Compared to traditional power generation, PV power generation offers advantages such as no risk of depletion, safety, no noise, and no pollution emissions, making it an indispensable pathway to achieving carbon neutrality. Therefore, deploying PV power plants in oilfields to replace traditional electricity supply has become a current trend in oilfield power generation.

[0003] Currently, most photovoltaic power stations are fixed structures. While their power generation is considerable, they also have significant drawbacks, such as large land area requirements, long sputtering cycles, high labor costs, and the inability to move them once the site is fixed, making them unsuitable for locations with urgent power needs. To address these shortcomings, mobile photovoltaic power stations have emerged. For example, patent publication number CN115800898A discloses a portable photovoltaic array generator container and its usage method, which includes a foldable photovoltaic power generation unit, a track assembly for extending or retracting the foldable photovoltaic power generation unit, electrical equipment, and a container. With manual traction, the foldable unit can be easily folded and placed back into the container for transport anywhere. This invention has a wide range of applications, is easy to install, and convenient to transport. It breaks away from the common practice of moving photovoltaic power generation units along tracks in ground-mounted and distributed photovoltaic power stations, enabling the unfolding or folding of the photovoltaic power generation unit. The folded photovoltaic power generation unit is then transported via a container, achieving rapid deployment and relocation of the photovoltaic power station. However, in this patent, both unfolding and folding of the photovoltaic power generation unit require manual traction, resulting in a large workload, numerous personnel, and relatively high labor costs. At the same time, relying on manual traction results in low safety performance and slow installation, thus slowing down the installation speed of photovoltaic power stations.

Detailed Implementation

[0035] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0036] like Figure 1-13 As shown, a mobile photovoltaic power station 2 is designed for easy unfolding and folding, facilitating transport and offering high mobility. The mobile photovoltaic power station includes a base 1 and a photovoltaic power station 2. The base 1 has a rectangular structure with a drive mechanism 3 on at least one of its left or right sides. Guide rails 4 extend into the base 1 on both the front and rear sides of the drive mechanism 3. Frame structures 5 are located on both the left and right sides of the base 1. The photovoltaic power station 2 is rotatably connected to the base 1. The photovoltaic power station 2 generates electricity and can be folded or unfolded. The drive mechanism 3 enables the unfolding and folding of the photovoltaic power station 2. When unfolded, the photovoltaic power station 2 absorbs solar energy and generates electricity; when folded, it is easy to transport and deploy. The guide rails 4 guide and support the unfolding and folding of the photovoltaic power station 2, ensuring smooth and rapid unfolding and folding, and facilitating quick installation. The frame structures 5 store and secure the folded photovoltaic power station 2, facilitating lifting and transport.

[0037] In this application, the photovoltaic power station 2 includes an even number of photovoltaic grid panels 21. These even-numbered photovoltaic grid panels 21 are sequentially connected end-to-end in an up-and-down manner, facilitating the unfolding and folding of the photovoltaic grid panels 21 along the guide rail 4. Only an even number of photovoltaic grid panels 21 ensures that both ends of the connected photovoltaic grid panels 21 are connected to the guide rail 4, thus guaranteeing the unfolding and folding of the photovoltaic grid panels 21 along the guide rail 4. Multiple drive connectors 24 are located below the photovoltaic power station 2. The number of drive connectors 24 is half the number of photovoltaic grid panels 21. The drive connectors 24 are connected to the drive mechanism 3 and the guide rail 4. That is, the photovoltaic grid panels 21 are connected to the drive mechanism 3 and the guide rail 4 through the drive connectors 24. The drive mechanism 3 drives the photovoltaic grid panels 21 to move automatically along the guide rail 4, achieving automatic unfolding and folding of the photovoltaic grid panels 21. This effectively reduces manual labor requirements, workload, and labor costs, and the unfolding and folding speed of the photovoltaic grid panels 21 is fast and efficient. Meanwhile, by connecting the drive mechanism 3 to a network and linking it to a remote control system, the movement of the drive mechanism 3 can be remotely controlled, enabling the photovoltaic power station 2 to be unfolded or folded, thus achieving unmanned operation in remote locations. In this application, the angle between two adjacent photovoltaic grid panels 21 after unfolding is 145°-160°, ensuring that the photovoltaic grid panels 21 can be effectively folded while ensuring effective energy absorption.

[0038] In this application, the drive mechanism 3 includes a geared motor 33, which is connected to at least one second chain 37 via a sprocket. The second chain 37 is laid along the length of the guide rail 4. The drive connector 24 is connected to the second chain 37, meaning that the geared motor 33 can drive the second chain 37 to rotate along the length of the guide rail 4 via the sprocket. The second chain 37 drives the drive connector 24 connected to it to move along the guide rail 4, and under the guidance of the guide rail 4, it drives the photovoltaic grid 21 to move on the guide rail 4. When the photovoltaic grid 21 moves towards the base 1, an even number of photovoltaic grids 21 can be folded towards the base 1; when the photovoltaic grid 21 moves away from the base 1, the photovoltaic power station 2 can be unfolded. Example

[0039] In this embodiment, there are two drive mechanisms 3, respectively located on the left and right sides of the base 1. The two drive mechanisms 3 operate independently, and can be activated individually or simultaneously. There are two photovoltaic power stations 2, symmetrically arranged on the base 1, forming a single main power station. Each photovoltaic power station 2 corresponds to one drive mechanism 3, which can be used to unfold the two photovoltaic power stations 2 to the left or right, or fold them up. The lower ends of the two adjacent photovoltaic grids 21 of the two photovoltaic power stations 2 are rotatably connected to the base 1, thus connecting the photovoltaic power station 2 to the base 1. This connection limits the movement of the photovoltaic grids 21 connected to the base 1, ensuring that they can only rotate around the base 1 during unfolding or folding without displacement. This ensures that all photovoltaic grids 21 are precisely laid along the guide rails 4 and fold smoothly into their designated positions.

[0040] like Figure 1 , 2 As shown in Figure 11, with the setting of two drive mechanisms 3, there are two schemes for laying the photovoltaic power station 2. Scheme 1 is that guide rails 4 are laid on both the left and right sides of the base 1. In this scheme, the drive mechanisms 3 on the left and right sides of the base 1 can be started and stopped simultaneously or sequentially, so that both photovoltaic power stations 2 can be unfolded, i.e., the double-track state.

[0041] like Figure 12 As shown in the second scheme, the guide rail 4 is laid only on one side of the base 1. In this scheme, the guide rail 4 is laid on the right side of the base 1 and not on the left side. Then, by activating the drive mechanism 3 on the right side of the base 1, the photovoltaic power station 2 on the right side can be unfolded, i.e., the single-sided track state.

[0042] As for whether to adopt Option 1 or Option 2, it can be determined based on the actual situation on site, including factors such as site area and power supply demand, to decide whether to deploy both photovoltaic power stations 2 or only deploy one photovoltaic power station 2 to meet the needs.

[0043] like Figure 3-4As shown, in this embodiment, starting from the first photovoltaic grid plate 21 on the side of the photovoltaic power station 2 near the drive mechanism 3, at least one drive connector 24 is provided below each photovoltaic grid plate 21 at intervals. That is, the photovoltaic grid plate 21 connected to the second chain 37 at the bottom drives one photovoltaic grid plate 21 relative to the inner side of the photovoltaic grid plate 21 to move, so that the photovoltaic grid plates 21 fold inward in pairs and finally fold together. If the photovoltaic grid plate 21 closest to the drive mechanism 3 in the photovoltaic power station 2 is designated as number 1, and then numbered sequentially from this photovoltaic grid plate 21 as 1, 2, 3, 4, 5...N, where N is an even number, then when the drive mechanism 3 starts to drive the photovoltaic power station 2 to begin unfolding, as the photovoltaic grid plate 21 numbered 1 moves to the left or right along the second chain 37, the photovoltaic grid plate 21 numbered 1 pulls the photovoltaic grid plate 21 numbered 21 rotatably connected to its upper end to move synchronously, the photovoltaic grid plate 21 numbered 3 pulls the photovoltaic grid plate 21 numbered 4 rotatably connected to its upper end to move synchronously, the photovoltaic grid plate 21 numbered 5 pulls the photovoltaic grid plate 21 numbered 6 rotatably connected to its upper end to move synchronously, and so on, until finally the photovoltaic grid plate 21 numbered N-1 pulls the photovoltaic grid plate 21 numbered N rotatably connected to its upper end to move synchronously, thus unfolding the photovoltaic grid plates 21 along the guide rail 4 in sequence. When the drive mechanism 3 starts to drive the photovoltaic power station 2 to fold, the photovoltaic grid plate 21 numbered N-1 pulls the photovoltaic grid plate 21 numbered N rotatably connected to its upper end to move synchronously, and folding begins with the bottom of the photovoltaic grid plate 21 numbered N as the fixed point. Then, the photovoltaic grid plate 21 numbered N-3 pulls the photovoltaic grid plate 21 numbered N-2 rotatably connected to its upper end to move synchronously and fold, and so on. The photovoltaic grid plate 21 numbered 1 pulls the photovoltaic grid plate 21 numbered 2 rotatably connected to its upper end to move synchronously and fold, so as to fold all the photovoltaic grid plates 21 of the photovoltaic power station 2.

[0044] In this embodiment, the number of drive connectors 24 provided for each photovoltaic grid 21 is the same as the number of second chains 37. The drive connectors 24 connect to the second chains 37. When there is only one second chain 37 on the side corresponding to the drive mechanism 3, this second chain 37 is positioned between the two guide rails 4. In this case, each photovoltaic grid 21 with drive connectors 24 has only one drive connector 24 below it, corresponding to the second chain 37, ensuring that the second chain 37 can drive the connected photovoltaic grid 21 to move. When there are two second chains 37 on the side corresponding to the drive mechanism 3, the two second chains 37 are positioned between the two guide rails 4 and on the front and rear sides of the reduction motor 33. In this case, each photovoltaic grid 21 with drive connectors 24 has two drive connectors 24 below it, corresponding to the two second chains 37, ensuring that the second chain 37 can drive the connected photovoltaic grid 21 to move.

[0045] like Figure 5As shown, in this embodiment, the drive connector 24 includes a first connecting plate 241 and a second connecting plate 243. Both the first connecting plate 241 and the second connecting plate 243 are connected to the photovoltaic grid plate 21. The first connecting plate 241 is a single unit, with a ratchet 242 on both its lower front and rear sides. These ratchet 242s connect to the second chain 37 via the ratchet teeth of the ratchet 242 inserting into the recessed teeth of the second chain 37, thus achieving toothed engagement between the ratchet 242 and the second chain 37. As the second chain 37 moves, it drives the ratchet 242 to move synchronously, thereby driving the photovoltaic grid plate 21 connected to it to move synchronously via the first connecting plate 241, ultimately achieving the folding or unfolding of the photovoltaic grid plate 21. In this embodiment, the second chain 37 is a double-link chain. There are two second connecting plates 243 arranged side by side. The lower ends of the two second connecting plates 243 are connected to a rotating shaft 244. An auxiliary roller 245 is rotatably connected in the middle of the rotating shaft 244. The auxiliary roller 245 is located in the middle of the two second connecting plates 243 and is rolled on the guide rail 4. It can roll along the guide rail 4 to realize the movement guidance of unfolding or folding of the photovoltaic grid panel 21, and reduce friction, making it convenient to unfold or fold. The two ends of the rotating shaft 244 extend from opposite sides of the two second connecting plates 243 and are each connected to a third connecting plate 246. At least one bearing 247 is provided on the adjacent sides of each of the two third connecting plates 246. The bearings 247 are fitted into the guide rail 4. The bearings 247 on the two third connecting plates 246 are engaged with both sides of the guide rail 4, limiting the movement of the auxiliary roller 245 and ensuring that the auxiliary roller 245 can move continuously along the guide rail 4 without deviation or separation from the guide rail 4, thus ensuring smooth unfolding or folding of the photovoltaic grid panel 21. Furthermore, the limiting structure of the bearings 247 reduces friction. In this embodiment, each third connecting plate 246 is connected to four bearings 247, which are divided into two groups, with each group of two bearings arranged side-by-side, further improving the limiting effect.

[0046] like Figure 8 As shown, in this embodiment, the guide rail 4 includes a fixing part 41, a guiding part 42, and a limiting part 43. The fixing part 41 has a Z-shaped cross-section and is located below the guiding part 42. It is used to support and fix the guiding part 42. The Z-shaped structure of the fixing part 41 facilitates the fixing of the guide rail 4 and provides stable support. The guiding part 42 is configured in conjunction with the auxiliary roller 245 to guide the rolling of the auxiliary roller 245. The two limiting parts 43 are respectively located on the front and rear sides of the guiding part 42. That is, by limiting the bearings 247 installed on the two third connecting plates 246 by the two limiting parts 43 respectively, the auxiliary roller 245 can be prevented from separating from the guiding part 242, thereby preventing the photovoltaic grid 21 from separating from the guide rail 4 and ensuring smooth unfolding or folding of the photovoltaic grid 21.

[0047] like Figure 6As shown, in this embodiment, the auxiliary roller 245 is a V-shaped roller, and the guide portion 42 is diamond-shaped. The V-shaped groove on the auxiliary roller 245 engages with the inverted V-shaped protrusion on the guide portion 42, thus achieving the cooperation between the auxiliary roller 245 and the guide portion 42. This ensures that the auxiliary roller 245 can move linearly along the guide rail 4, preventing deviation and jamming. The limiting portion 43 is a horizontally arranged plate, allowing the bearing 247 to roll along the lower surface of the limiting portion 43 while simultaneously restricting the upward movement of the bearing 247.

[0048] like Figure 7 As shown, in this embodiment, there are two second chains 37. By pulling the photovoltaic grid 21 with the two second chains 37, the force on the photovoltaic grid 21 can be uniform and large, making the unfolding or folding of the photovoltaic grid 21 smoother. The drive mechanism 3 includes a first fixed frame 31 and a second fixed frame 32. Both the first fixed frame 31 and the second fixed frame 32 are connected to the base 1. The two second fixed frames 32 are respectively arranged on the front and rear sides of the first fixed frame 31. The reduction motor 33 is mounted on the first fixed frame 31. A first sprocket set 34 is mounted on the first fixed frame 31. A first chain 35 is connected between the reduction motor 33 and the first sprocket set 34. Each of the two second fixed frames 32 is provided with a second sprocket set 36. The two second chains 37 are respectively connected to the second sprocket sets 36 on the two second fixed frames 32. A drive shaft 38 is connected between the first sprocket set 34 and the two second sprocket sets 36. The first mounting bracket 31 is used to mount the reduction motor 33 and the first sprocket assembly 34, and the second mounting bracket 32 ​​is used to mount the second sprocket assembly 36. The reduction motor 33 can drive the first sprocket assembly 34 to rotate via the first chain 35. The first sprocket assembly 34 drives the second sprocket assembly 36 to rotate via the drive shaft 37, and the second sprocket assembly 36 can drive the second chain 37 to rotate. Both the first sprocket assembly 34 and the second sprocket assembly 36 include two drive wheels and at least one tensioning wheel. Example

[0049] like Figure 13 As shown, unlike Embodiment 1, in this embodiment, the drive mechanism 3 is a single unit located on one side of the base 1, while the photovoltaic power station 2 has one unit. The lower end of a photovoltaic grid plate 21 of the photovoltaic power station 2, located away from the drive mechanism 3, is rotatably connected to the base 1. In this design, the drive mechanism 3 is located on the right side of the base 1, and two guide rails 4 are provided on the right side of the base 1. When the photovoltaic power station 2 needs to be unfolded, the reduction motor 33 of the drive mechanism 3 drives two second chains 37 to rotate. The two second chains 37 move synchronously through the ratchet 242 of the drive connector 24, thereby driving the photovoltaic grid plate 21 connected to the drive connector 24 to move synchronously, thus realizing the unfolding or folding of the photovoltaic power station 2.

[0050] like Figure 9 As shown in the present application, the base 1 is provided with a first hinge 11 for connecting to the photovoltaic power station 2. Specifically, the innermost photovoltaic grid panel 21 of each photovoltaic power station 2 is connected to the base 1 via the first hinge 11, ensuring that the bottom of the photovoltaic grid panel 21 can only rotate relative to the base 1 and cannot move horizontally. This ensures smooth unfolding and folding of the photovoltaic power station 2 and guarantees the connection between the photovoltaic power station 2 and the base 1. An even number of photovoltaic grid panels 21 are connected end-to-end via a second hinge 22, ensuring that adjacent photovoltaic grid panels 21 can rotate relative to each other, allowing the even number of photovoltaic grid panels 21 to unfold or fold. A quick clamp 23 is connected to the front and rear sides of every two adjacent photovoltaic grid panels 21. This clamp is used to fix and lock the relative positions of the even number of photovoltaic grid panels 21 after they are folded together, ensuring the stability of the photovoltaic power station 2 after folding, facilitating the handling and deployment of the photovoltaic power station 2, and improving safety.

[0051] like Figure 9-10 As shown in the diagram, in this application, the frame structure 5 includes a rectangular frame 51. Multiple cables 52 are installed inside the frame 51. The frame 51 can be combined with the base 1 to form a frame structure for housing the photovoltaic power station 2, facilitating its transport and providing protection. The cables 52 enhance the structural strength of the frame 51, improving the stability of the photovoltaic power station 2 during transport and deployment. A level bubble level is installed on the guide rail 4 to ensure its levelness, adapting to uneven terrain and enabling rapid installation. This effectively reduces installation time, improves efficiency, and ensures smooth and rapid deployment of the photovoltaic power station 2.

[0052] In the scheme of this application, the mobile photovoltaic power station is also equipped with a high-pressure water gun for cleaning the photovoltaic grid 21, ensuring that the photovoltaic grid 21 panel is clean and can effectively improve the power generation rate.

[0053] In this application, the mobile photovoltaic power station can operate in energy storage, grid-connected, and off-grid modes. It is not limited to grid-connected power generation; it can also store electrical energy or provide power to other equipment.
