Description

TECHNICAL FIELD

[0001] The present application relates to a push-pull type mobile photovoltaic power generation platform, belonging to the technical field of photovoltaic power generation. BACKGROUND

[0002] Solar energy, as a clean and renewable energy, is continuously developed and utilized on a large scale. Photovoltaic power generation will significantly increase its share in the global energy structure in the future, and is expected to become one of the main energy sources by the middle of this century. At present, the main installation methods of photovoltaic power generation systems include fixed support type and floating type.

[0003] Fixed support type photovoltaic system: the photovoltaic support is fixed to the ground or roof through pile foundation, with simple structure and wide application. However, this method needs to permanently or semi-permanently occupy land resources, with large amount of civil construction and high cost. Once built, it is difficult to move and cannot meet the demand for temporary and mobile power supply, with relatively low land utilization rate.

[0004] Floating type photovoltaic system: the photovoltaic panel is installed on the floating body in water areas such as lakes, reservoirs and offshore, saving land on land. However, its application scenarios are limited, with high initial investment and maintenance cost, and the same limitation of immobility.

[0005] Both of the above two traditional methods have a common problem: the photovoltaic array is fixed in one place, resulting in long-term occupation of the land or water surface in the area, which cannot be flexibly adjusted. In addition, the daily inspection and maintenance tasks of large-scale photovoltaic power stations are heavy, with safety hazards and high labor costs. In response to natural disasters, emergencies or emergency power supply demand in remote areas, traditional fixed photovoltaic systems are difficult to achieve rapid deployment and energy support.

[0006] To solve the demand for mobile power generation, mobile power sources such as diesel generators have appeared in the market. However, diesel generators have the disadvantages of loud noise, heavy pollution, high operating cost and dependence on fossil fuels, which do not meet the green and low-carbon development direction. In addition, some mobile power generation devices with photovoltaic panels simply installed on trailers have also appeared, but these devices usually have problems such as inconvenience in unfolding and storing photovoltaic panels, still large transportation volume, poor structural stability, low automation level, and photovoltaic panels easily damaged during transportation and in bad weather. The energy storage part of these devices mostly uses traditional liquid electrolyte batteries, which have the disadvantages of limited energy density, short cycle life, slow charging speed and high safety risk.

[0007] Therefore, there is an urgent need in the field for a new type of mobile photovoltaic power generation solution that integrates efficient power generation, convenient movement, rapid deployment, intelligent protection, automated operation and safe energy storage, to overcome the many defects of the prior art. SUMMARY

[0008] The purpose of this invention is to provide a push-pull mobile photovoltaic power generation platform. This invention aims to solve the problems of fixed deployment, immobility, large footprint, and inconvenient operation and maintenance of traditional photovoltaic systems. This invention features rapid transportation and deployment, fully automatic remote control, intelligent protection against severe weather, and safe energy storage and power supply. It significantly improves land utilization, reduces construction costs, and provides an efficient and flexible clean energy solution for emergency power supply and distributed energy applications.

[0009] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a push-pull mobile photovoltaic power generation platform, including a container body, a container body slide rail inside the container body, and multiple photovoltaic power generation modules slidably connected on the container body slide rail. Each photovoltaic power generation module includes a bracket, a photovoltaic panel mounted on the bracket, and a pulley above the bracket and a slide rail below the bracket. The multiple photovoltaic power generation modules are connected sequentially from top to bottom, wherein the slide rail of the upper photovoltaic power generation module contacts the pulley of the lower photovoltaic power generation module, so that the pulley of the lower photovoltaic power generation module can roll on the slide rail of the upper photovoltaic power generation module. The pulley of the uppermost photovoltaic power generation module contacts the container body slide rail, and the lowermost photovoltaic power generation module is fixedly connected to a drive trolley, which is used to drive the photovoltaic power generation module to unfold or retract along the container body slide rail.

[0010] The aforementioned push-pull mobile photovoltaic power generation platform has a support leg on each of the photovoltaic power generation modules for supporting the photovoltaic power generation modules when they are unfolded.

[0011] In the aforementioned push-pull mobile photovoltaic power generation platform, both ends of the slide rail are equipped with limit blocks to prevent the pulleys from derailing.

[0012] In the aforementioned push-pull mobile photovoltaic power generation platform, the bottom of the support leg is provided with a support wheel, and an elastic connector is provided between the support leg and the support wheel to automatically support and adapt to uneven ground when unfolded. The elastic connector can be a buffer spring.

[0013] The aforementioned push-pull mobile photovoltaic power generation platform includes a drive trolley comprising a vehicle body, wheels, and a three-in-one motor. The wheels are located on the left and right sides of the vehicle body, and the three-in-one motor is connected to the wheels for drive. The three-in-one motor includes a motor, a reducer, and a brake.

[0014] In the aforementioned push-pull mobile photovoltaic power generation platform, the wheels on the left and right sides of the drive trolley are driven by independent three-in-one motors. Each three-in-one motor has an encoder at its output end for real-time measurement of the travel distance and is connected to a control unit for adjusting the speed of the three-in-one motors on both sides to correct the deviation of the travel trajectory.

[0015] The aforementioned push-pull mobile photovoltaic power generation platform also includes an energy storage battery, installed inside the container, for storing the electrical energy generated by the photovoltaic power generation modules.

[0016] The aforementioned push-pull mobile photovoltaic power generation platform also includes a remote control system for remotely controlling the movement of the drive vehicle and the deployment and retraction of the photovoltaic power generation modules.

[0017] The aforementioned push-pull mobile photovoltaic power generation platform includes an upper plate and a lower plate on the slide rail. The pulley is disposed between the upper plate and the lower plate and contacts the lower plate. The upper plate is used to prevent the pulley from disengaging from the lower plate.

[0018] Compared with the prior art, the present invention has at least the following beneficial effects:

[0019] (1) The present invention has high mobility and rapid deployment capability. The entire power generation platform is integrated in a standard container and can be quickly transported to any location required by conventional means of transport, realizing the plug-and-play and rapid deployment of photovoltaic power generation units. It is particularly suitable for emergency power supply, temporary work area power supply and remote area power supply scenarios.

[0020] (2) The present invention significantly improves land utilization and reduces construction costs. The platform of the present invention adopts a mobile design and does not permanently occupy land, which solves the problems of large land area and high civil engineering costs of traditional fixed photovoltaic power stations. The platform can flexibly utilize scattered open spaces to achieve "multiple uses of one place", which greatly reduces the initial construction investment of photovoltaic power stations.

[0021] (3) The present invention uses a push-pull retractable structure to retract all photovoltaic power generation modules into the container at night, in rainy or bad weather, effectively avoiding the photovoltaic panels from being eroded and physically damaged by external environments such as wind, sand, hail, and humidity, significantly extending the service life of the equipment and reducing maintenance costs.

[0022] (4) By setting support legs with buffer springs at both ends of the multi-level photovoltaic power generation module, the present invention can automatically provide effective support when the platform is fully extended, which overcomes the deformation problem caused by gravity sagging of the multi-layer push-pull structure and ensures the overall structural strength and stability of the power generation array in the extended state.

[0023] (5) The drive trolley of this invention adopts dual motors for independent drive and is equipped with encoder feedback. The control system can correct deviations in real time, ensuring the straightness of the driving trajectory during deployment and retraction, preventing the problem of pulley jamming caused by deviation, and achieving a smooth and reliable process. Combined with the remote control system, the platform can be operated without human intervention and with full automation, greatly reducing the need for manpower.

[0024] (6) This invention integrates power generation, energy storage, transportation and automatic control, and provides a safe, economical, efficient and flexible distributed photovoltaic power generation solution, which helps to promote energy conservation and emission reduction, improve the resilience and reliability of energy supply, and has significant positive benefits in social, economic and environmental aspects.

[0033] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Detailed Implementation

[0034] Embodiment 1 of the present invention: A push-pull mobile photovoltaic power generation platform includes a container body 1. The container body 1 has a container slide rail 2 inside. Both ends of the container slide rail 2 are either closed or equipped with limiting blocks 9. Multiple photovoltaic power generation modules 3 are slidably connected to the container slide rail 2. Each photovoltaic power generation module 3 includes a bracket 10, a photovoltaic panel 7 mounted on the bracket 10, and pulleys 6 above and below the bracket 10. The multiple photovoltaic power generation modules 3 are connected sequentially from top to bottom. The upper photovoltaic panel... The slide rail 8 of the power generation module 3 contacts the pulley 6 of the lower photovoltaic power generation module 3, allowing the pulley 6 of the lower photovoltaic power generation module 3 to roll on the slide rail 8 of the upper photovoltaic power generation module 3. The pulley 6 of the uppermost photovoltaic power generation module 3 contacts the slide rail 2 of the housing. Both ends of the slide rail 8 are provided with limit blocks 9 to prevent the pulley 6 from derailing. The lowermost photovoltaic power generation module 3 is fixedly connected to a drive trolley 5, which is used to drive the photovoltaic power generation module 3 to unfold or retract along the slide rail 2 of the housing.

[0035] During deployment, the drive trolley 5 can be moved by electricity. During the movement of the drive trolley 5, the bottom photovoltaic power generation module 3 is first pulled out. When the pulley 6 of the bottom photovoltaic power generation module 3 moves to the stop 9, it stops moving. However, the upper photovoltaic power generation module 3 can be pulled out by the drive trolley 5. This process is repeated. Multiple photovoltaic power generation modules are pulled out of the container body 1 in sequence by the movement of the drive trolley 5, thus achieving deployment. During retraction, the drive trolley 5 moves in the opposite direction, causing the pulley 6 of the bottom photovoltaic power generation module 3 to move to the stop 9 at the other end, thereby dragging the upper photovoltaic power generation module 3 back, and finally putting all photovoltaic power generation modules 3 into the container body 1.

[0036] Embodiment 2 of the present invention: A push-pull mobile photovoltaic power generation platform includes a container body 1. The container body 1 has a sliding rail 2 inside. Both ends of the sliding rail 2 are either closed or have limit blocks 9. Multiple photovoltaic power generation modules 3 are slidably connected to the sliding rail 2. Each photovoltaic power generation module 3 includes a bracket 10, a photovoltaic panel 7 mounted on the bracket 10, and pulleys 6 above and below the bracket 10. The multiple photovoltaic power generation modules 3 are connected sequentially from top to bottom. The upper photovoltaic panel... The slide rail 8 of the power generation module 3 contacts the pulley 6 of the lower photovoltaic power generation module 3, allowing the pulley 6 of the lower photovoltaic power generation module 3 to roll on the slide rail 8 of the upper photovoltaic power generation module 3. The pulley 6 of the uppermost photovoltaic power generation module 3 contacts the slide rail 2 of the housing. Both ends of the slide rail 8 are provided with limit blocks 9 to prevent the pulley 6 from derailing. The lowermost photovoltaic power generation module 3 is fixedly connected to a drive trolley 5, which is used to drive the photovoltaic power generation module 3 to unfold or retract along the slide rail 2 of the housing.

[0037] Each photovoltaic power generation module 3 is equipped with a support leg 4 to support the photovoltaic power generation module 3 when it is unfolded. When the photovoltaic power generation module 3 is fully unfolded, it will sag due to its own weight, causing structural deformation. Support legs 4 are installed at both ends of the photovoltaic power generation module 3 at regular intervals. Support wheels 13 are provided at the bottom of the support legs 4. An elastic connector 14 is provided between the support legs 4 and the support wheels 13 to automatically support and adapt to uneven ground when unfolded, ensuring stability when fully unfolded.

[0038] Embodiment 3 of the present invention: A push-pull mobile photovoltaic power generation platform includes a container body 1. The container body 1 has a container slide rail 2 inside. Both ends of the container slide rail 2 are either closed or have limit blocks 9. Multiple photovoltaic power generation modules 3 are slidably connected to the container slide rail 2. Each photovoltaic power generation module 3 includes a bracket 10, a photovoltaic panel 7 mounted on the bracket 10, and pulleys 6 above and below the bracket 10. The multiple photovoltaic power generation modules 3 are connected sequentially from top to bottom. The upper photovoltaic panel... The slide rail 8 of the power generation module 3 contacts the pulley 6 of the lower photovoltaic power generation module 3, allowing the pulley 6 of the lower photovoltaic power generation module 3 to roll on the slide rail 8 of the upper photovoltaic power generation module 3. The pulley 6 of the uppermost photovoltaic power generation module 3 contacts the slide rail 2 of the housing. Both ends of the slide rail 8 are provided with limit blocks 9 to prevent the pulley 6 from derailing. The lowermost photovoltaic power generation module 3 is fixedly connected to a drive trolley 5, which is used to drive the photovoltaic power generation module 3 to unfold or retract along the slide rail 2 of the housing.

[0039] Each photovoltaic power generation module 3 is equipped with a support leg 4 to support the photovoltaic power generation module 3 when it is unfolded. When the photovoltaic power generation module 3 is fully unfolded, it will sag due to its own weight, causing structural deformation. Support legs 4 are installed at both ends of the photovoltaic power generation module 3 at regular intervals. Support wheels 13 are provided at the bottom of the support legs 4. An elastic connector 14 is provided between the support legs 4 and the support wheels 13 to automatically support and adapt to uneven ground when unfolded, ensuring stability when fully unfolded.

[0040] The driving vehicle 5 includes a body 501, wheels 502, and a three-in-one motor. The wheels 502 are located on the left and right sides of the body 501. The three-in-one motor is driven by the wheels 502 and includes a motor, a reducer, and a brake. The wheels 502 on the left and right sides of the driving vehicle 5 are driven by independent three-in-one motors. Each three-in-one motor has an encoder at its output end for real-time measurement of the travel distance and is connected to a control unit for adjusting the speed of the three-in-one motors on both sides to correct the deviation of the travel trajectory. During the operation of the driving vehicle 5, the travel trajectory may deviate, causing the pulley 6 to jam with the slide rail 8. Therefore, by installing encoders at the output ends of the three-in-one motors and using two encoders to measure the travel distance on both sides in real time, the rotation speed of the three-in-one motors on both sides can be dynamically adjusted to reduce the deviation of the travel trajectory.

[0041] Embodiment 4 of the present invention: A push-pull mobile photovoltaic power generation platform includes a container body 1. The container body 1 has a container slide rail 2 inside. Both ends of the container slide rail 2 are either closed or also equipped with limiting blocks 9. Multiple photovoltaic power generation modules 3 are slidably connected to the container slide rail 2. Each photovoltaic power generation module 3 includes a bracket 10, a photovoltaic panel 7 mounted on the bracket 10, and a pulley 6 above the bracket 10 and a slide rail 8 below it. The multiple photovoltaic power generation modules 3 are connected sequentially from top to bottom. The slide rail 8 of the upper photovoltaic power generation module 3 contacts the pulley 6 of the lower photovoltaic power generation module 3, causing the lower... The pulley 6 of the photovoltaic power generation module 3 in the upper part can roll on the slide rail 8 of the photovoltaic power generation module 3 in the upper part. The pulley 6 of the uppermost photovoltaic power generation module 3 is in contact with the slide rail 2 of the box. Both ends of the slide rail 8 are provided with limit blocks 9 to prevent the pulley 6 from derailing. The slide rail 8 includes an upper plate 11 and a lower plate 12. The pulley 6 is disposed between the upper plate 11 and the lower plate 12 and is in contact with the lower plate 12. The upper plate 11 is used to prevent the pulley from detaching from the lower plate 12. The photovoltaic power generation module 3 at the bottom is fixedly connected to a drive trolley 5. The drive trolley 5 is used to drive the photovoltaic power generation module 3 to unfold or retract along the slide rail 2 of the box.

[0042] Each photovoltaic power generation module 3 is equipped with a support leg 4 to support the photovoltaic power generation module 3 when it is unfolded. When the photovoltaic power generation module 3 is fully unfolded, it will sag due to its own weight, causing structural deformation. Support legs 4 are installed at both ends of the photovoltaic power generation module 3 at regular intervals. Support wheels 13 are provided at the bottom of the support legs 4. An elastic connector 14 is provided between the support legs 4 and the support wheels 13 to automatically support and adapt to uneven ground when unfolded, ensuring stability when fully unfolded.

[0043] The driving vehicle 5 includes a body 501, wheels 502, and a three-in-one motor. The wheels 502 are located on the left and right sides of the body 501. The three-in-one motor is driven by the wheels 502 and includes a motor, a reducer, and a brake. The wheels 502 on the left and right sides of the driving vehicle 5 are driven by independent three-in-one motors. Each three-in-one motor has an encoder at its output end for real-time measurement of the travel distance and is connected to a control unit for adjusting the speed of the three-in-one motors on both sides to correct the deviation of the travel trajectory. During the operation of the driving vehicle 5, the travel trajectory may deviate, causing the pulley 6 to jam with the slide rail 8. Therefore, by installing encoders at the output ends of the three-in-one motors and using two encoders to measure the travel distance on both sides in real time, the rotation speed of the three-in-one motors on both sides can be dynamically adjusted to reduce the deviation of the travel trajectory.

[0044] Furthermore, it also includes an energy storage battery, installed inside the container body 1, for storing the electrical energy generated by the photovoltaic power generation module 3;

[0045] Furthermore, it also includes a remote control system for remotely controlling the movement of the drive vehicle 5 and the deployment and retraction of the photovoltaic power generation module 3.

[0046] This mobile photovoltaic power generation platform is integrated into a standard container. It can be transported by truck to a designated location and then the photovoltaic power generation module 3 can be remotely controlled to unfold, achieving automated operation, saving manpower and material resources, and reducing carbon emissions in the power generation field.

[0047] Working principle: This invention utilizes a scalable, modular push-pull structure to achieve mobile deployment and intelligent protection of photovoltaic power generation units. The entire system is integrated within a standard shipping container, and through innovative mechanical transmission and intelligent control systems, it completes the transition from transport to operational status.

[0048] During operation, the drive trolley acts as the power source, moving along a preset track. Through its fixed connection with the bottom photovoltaic power generation module, it drives the entire module group to unfold or retract. Each photovoltaic power generation module adopts a unique nested design: the bottom of the upper module has a slide rail, and the top of the lower module is equipped with pulleys. When the drive trolley moves outward, the bottom module is pulled out. After its slide rail contacts the pulleys of the upper module, the upper module unfolds synchronously through the transmission action of the limiting blocks, forming a step-by-step pulling-out linkage effect, ultimately forming a large-area photovoltaic array.

[0049] To ensure structural stability after deployment, the system incorporates support leg mechanisms at key locations. The wheels and elastic elements at the base of the support legs adapt to uneven ground, providing effective support and preventing structural deformation. The slide rail employs an upper and lower plate structure, ensuring smooth pulley rotation while preventing derailment and guaranteeing operational reliability.

[0050] The drive system employs an independent drive scheme for the left and right wheels, with each motor equipped with an encoder to monitor driving data in real time. The control system dynamically adjusts the motor output by comparing the speed difference between the two wheels, achieving precise correction of the driving trajectory and avoiding jamming caused by skewness.

[0051] The platform integrates energy storage units and a remote control system, supporting unattended operation. When there is sufficient sunlight, the deployed photovoltaic panels generate electricity and store it; when encountering severe weather or needing to be moved, the system can be quickly retracted into a container, providing comprehensive protection for the equipment.

[0052] This platform, through the organic combination of modular push-pull structure and intelligent control, enables the rapid deployment, flexible movement, and intelligent protection of photovoltaic power generation units, significantly improving land utilization and reducing construction costs.
