Description

Technical Field

[0001] This invention relates to the field of photovoltaic power generation equipment technology, and in particular to a containerized photovoltaic support system and its opening and closing method. Background Technology

[0002] With the rapid development of renewable energy technologies, photovoltaic (PV) power generation systems are increasingly being used in field operations, emergency power supply, and temporary power needs. To improve deployment efficiency and transportation convenience, integrating PV support systems into standard shipping containers has become an important trend. Currently, various foldable PV support structures have been proposed, aiming to achieve compact storage during transport and rapid on-site deployment.

[0003] However, existing technologies still have some shortcomings that limit the efficiency and reliability of photovoltaic support systems in practical applications. First, although most systems have folding capabilities, they still occupy a significant amount of space when folded, making it difficult to achieve high-density, compact arrangement within standard shipping containers. Second, the deployment process generally relies on manual assembly or additional power equipment, resulting in low on-site deployment efficiency. Third, while some solutions include angle adjustment structures, they lack integrated mechanisms that combine limiting and elastic reset functions. Finally, when releasing multiple support units on inclined tracks, existing systems generally lack effective blocking components, easily causing multiple components to slide out simultaneously and collide with each other, severely impacting the safety and controllability of the deployment process. Summary of the Invention

[0004] The purpose of this invention is to solve the technical problems of existing photovoltaic support systems when deployed in the field or temporary locations, such as inconvenient transportation and storage, cumbersome deployment operations, and difficulty in controlling the deployment sequence.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] According to a first aspect of the present invention, a container-mounted photovoltaic (PV) support system is provided, comprising: a container; a plurality of PV support assemblies, each PV support assembly consisting of two PV support units hinged together, with adjacent PV support assemblies connected by rolling elements; an angle adjustment assembly disposed between the two PV support units in each assembly, for limiting the unfolding angle between the two PV support units and providing a folding and resetting force; a guide rail disposed inside the container; an exit slide disposed at the front end of the container and opposite to the guide rail; a wheel mounting portion disposed at the front end of the PV support unit located at the front side in each PV support assembly, for detachably mounting wheels; a blocking member movably disposed on the exit slide for blocking the rolling elements; and a control member linked to the blocking member for controlling the blocking member to switch between a blocking position and a yielding position.

[0007] Optionally, the angle adjustment assembly includes a steel wire rope and an elastic element. The steel wire rope is connected between the bottoms of two photovoltaic support units in each group, one end of the elastic element is connected to the steel wire rope, and the other end of the elastic element is connected to the hinge axis between the two photovoltaic support units.

[0008] Alternatively, the elastic element may be a spring.

[0009] Optionally, the rolling element is a guide roller, the guide rail is a roller guide rail that cooperates with the guide roller, and the lead-out slide is a downwardly inclined slide, the upper end of which smoothly connects with the front end of the roller guide rail.

[0010] Optionally, the wheel mounting portion is a mounting shaft extending outward from both sides of the front end of the photovoltaic support unit.

[0011] Optionally, the blocking element is a stop pin, and the control element is a foot pedal and a transmission element that is pulsatorically connected to the stop pin; when the foot pedal is not pressed, the stop pin extends out of the upper surface of the lead-out slide to form the blocking position; when the foot pedal is pressed, the stop pin retracts into the lead-out slide to form the yielding position.

[0012] Optionally, the photovoltaic panels can be detachably mounted on each photovoltaic support unit using threaded fasteners.

[0013] Alternatively, in the stowed state, each photovoltaic support assembly can be folded and housed inside the container, with the overall space occupied being the same as that of a single photovoltaic support unit.

[0014] According to a second aspect of the present invention, a method for opening and closing a containerized photovoltaic support system based on the above-described containerized photovoltaic support system is provided, comprising the following steps:

[0015] Move the first set of photovoltaic support components along the guide rail to the lead-out slide;

[0016] Install wheels on the wheel mounting section of the first group of photovoltaic support components;

[0017] Operate the control unit to switch the blocking member from the blocking position to the opening position, release the rolling member of the first group of photovoltaic support components, and let the first group of photovoltaic support components slide down the lead-out slide to the ground;

[0018] Reset the blocking element to the blocking position;

[0019] Repeat the above steps to deploy each subsequent set of photovoltaic support components to the ground in sequence.

[0020] Optionally, after the first set of photovoltaic support components slides down to the ground, its rolling elements and wheels work together to support it and roll on the ground; and before the next set of photovoltaic support components unfolds, the current set of photovoltaic support components has completely left the lead-out slide.

[0021] The advantages of implementing this invention are:

[0022] 1. Space utilization is significantly improved. After folding, the overall storage size is compressed to the size of a single photovoltaic support unit, which can be loaded in large quantities at high density in a standard container;

[0023] 2. The unfolding efficiency is greatly improved. It can unfold without power by relying on gravity sliding and foot-operated limit pin linkage control.

[0024] 3. The unfolding process is safe and controllable. The limit pin and foot pedal work together to prevent the risk of multiple groups sliding out simultaneously. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example 1

[0032] like Figures 1-3 As shown, a container-mounted photovoltaic (PV) support system includes a container 1, several sets of PV support components 3, an angle adjustment component 8, a guide rail 4, an extension slide 5, a wheel mounting part 7, a blocking component, and a control component. Each PV support component 3 consists of two PV support units 2 connected by a hinge shaft, and adjacent PV support components 3 are interconnected by rolling elements 6. The angle adjustment component 8 is located between the two PV support units 2 in each group, used to limit the unfolding angle between the two PV support units 2 and provide a restoring force during folding. The guide rail 4 is fixedly installed on the inner bottom surface of the container, and the extension slide 5 is located at the front end of the container, with its upper end smoothly engaging with the front end of the guide rail 4 to form a continuous guide path. The wheel mounting part 7 is located at the front end of the PV support unit 2 on the front side of each PV support component 3, used for detachably installing the wheel 7. The blocking component is movably mounted on the extension slide 5, used to prevent the rolling elements 6 from continuing to move forward when needed. The control component is linked to the blocking component, enabling the blocking component to switch between a blocking position and a yielding position.

[0033] The inner sidewall of the container is provided with several swing positioning parts 10 for fixing the photovoltaic bracket components in the stored state inside the container. The swing positioning parts 10 can rotate up and down. When the photovoltaic bracket components in the stored state are set inside the container, the swing positioning parts 10 are set in the gap between adjacent photovoltaic bracket components to prevent movement and collision during transportation.

[0034] A steel wire rope 801 connects the bottoms of two photovoltaic support units 2 in each photovoltaic support assembly 3. One end of the steel wire rope 801 is fixed to the bottom of one photovoltaic support unit 2, and the other end is fixed to the bottom of the other photovoltaic support unit 2. One end of an elastic element 802 is connected to the middle of the steel wire rope 801, and the other end is connected to the hinge axis between the two photovoltaic support units 2. The elastic element 802 is specifically a spring, which is stretched when the photovoltaic support assembly 3 is unfolded, thereby applying an inward pulling force to the two photovoltaic support units 2 and limiting their unfolding angle; during the folding process, the spring releases the stored elastic potential energy, pushing the two photovoltaic support units 2 to fold inward, achieving automatic reset.

[0035] Roller 6 is a guide roller installed at the connection point of two adjacent photovoltaic support modules 3. Guide rail 4 is a roller guide rail that cooperates with the guide roller to ensure that the photovoltaic support module 3 moves smoothly along a predetermined path inside the container. The exit slide 5 is a downward-sloping slide with its inclination direction facing the ground outside the container, which facilitates the smooth sliding out of the photovoltaic support module 3 by gravity.

[0036] The mounting part of the walking wheel 7 is a mounting shaft that extends horizontally outward from both sides of the front end of the photovoltaic support unit 2. The mounting shaft has a simple structure and facilitates the quick installation or removal of the large-sized walking wheel 7 to support the photovoltaic support assembly 3 to move on the ground.

[0037] The blocking component is a stop pin 501, and the control components include a foot pedal 9 and a transmission component that is pulsatorically connected to the stop pin 501. When the foot pedal 9 is not pressed, the stop pin 501 extends out of the upper surface of the guide slide 5 under the action of the transmission component, and is in a blocking position to prevent the rolling component 6 from passing through; when the foot pedal 9 is pressed, the stop pin 501 is driven by the transmission component to retract into the guide slide 5, forming a clearance position, allowing the rolling component 6 to pass smoothly and roll down the inclined slide to the ground.

[0038] The photovoltaic panels are detachably installed on the upper surface of each photovoltaic support unit 2 using threaded fasteners, which facilitates disassembly during transportation and rapid on-site installation.

[0039] In its stowed state, all photovoltaic support components 3 are folded and neatly stacked inside the container. Since the thickness of each component after folding is close to that of a single photovoltaic support unit 2, the overall space occupied is only the space of a single photovoltaic support unit 2, which greatly improves the utilization rate of the container's internal space.

[0040] In operation, first open the front door of the container and push the foremost photovoltaic support assembly 3 along the guide rail 4 to the entrance of the lead-out slide 5. At this point, the stop pin 501 is in the blocking position to prevent accidental slippage. Then, install the traveling wheels 7 on the mounting shaft of the front photovoltaic support unit 2 of this assembly. The operator steps on the foot pedal 9, the stop pin 501 retracts, and the rolling parts 6 of this photovoltaic support assembly 3 roll down the inclined lead-out slide 5 to the ground under gravity. The traveling wheels 7 and the rolling parts 6 together support the assembly's stable movement on the ground. After this assembly is deployed, release the foot pedal 9 to reset the stop pin 501, then push the next photovoltaic support assembly 3 to the entrance of the lead-out slide 5. Repeat the above steps of installing and releasing the traveling wheels 7 to complete the deployment of all components. The entire process requires no hoisting equipment, is easy to operate, and is suitable for rapid deployment of photovoltaic power generation systems in the field.

[0041] Example 2

[0042] A method for opening and closing a containerized photovoltaic support system includes the following steps:

[0043] S1: Move the first set of photovoltaic support components along the guide rail to the lead-out slide;

[0044] S2: Install wheels on the wheel mounting section of the first set of photovoltaic support modules;

[0045] S3: Operate the control unit to switch the blocking unit from the blocking position to the yielding position, release the rolling parts of the first group of photovoltaic support components, and let the components slide down the downward inclined guide slide to the ground under the action of gravity.

[0046] S4: Reset the blocking component to the blocking position;

[0047] S5: Repeat steps S1 to S4 to deploy the subsequent photovoltaic support components to the ground in sequence.

[0048] In the first set of photovoltaic support components, after the components slide down to the ground, their rolling parts and the installed wheels together support the entire component and enable it to roll on the ground.

[0049] The structure and fit of the aforementioned guide rail, lead-out slide, rolling element, wheel mounting part, blocking element, and control element can be found in the corresponding description in Embodiment 1, and will not be repeated here. The angle adjustment component adopts a combination structure of steel wire rope and spring, which limits the included angle between the two photovoltaic support units during the unfolding process and provides a restoring force when folded. This part of the structure has also been described in detail in Embodiment 1. The photovoltaic panels are detachably installed on each photovoltaic support unit by threaded fasteners. In the folded state, the overall space occupied by all components is the same as the space of a single photovoltaic support unit. Related details are also referred to in Embodiment 1.

[0050] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
