Description

Technical Field

[0001] This invention relates to the field of photovoltaic energy storage, specifically to an intelligent mobile multifunctional photovoltaic energy storage monitoring device, comprising a photovoltaic receiving unit, a folding control unit, a new energy battery unit, a voltage conversion unit, a control unit, a vertical frame unit, an extension unit, and a lighting and communication unit. The lighting and communication unit and the extension unit are combined to form a top-mounted device. The photovoltaic receiving unit, folding control unit, new energy battery unit, voltage conversion unit, and control unit are fixed on the vertical frame unit, forming an electrical control device. The photovoltaic receiving unit and folding control unit work to unfold the multi-layer photovoltaic receiving unit, and after adjustment, maximize the output voltage of the photovoltaic receiving unit. The voltage is converted into electrical energy by the voltage conversion unit and used by all units. The top-mounted device and the electrical control device can be equipped with protective boxes, allowing them to be transported by airdrop to different road environments to provide emergency lighting and communication. The protective boxes and walls of each device are modular and reusable. The photovoltaic receiving unit generates multiple voltages, which are used by the folding control unit, the new energy battery unit, the extension unit, the voltage conversion unit, the lighting and communication unit, and the control unit, respectively. During operation, the extension unit extends the height; the folding control unit unfolds two or more layers of photovoltaic receiving units, and the direction is then manually adjusted or controlled by the control unit to maximize the output voltage of the photovoltaic receiving unit; the new energy battery unit can store excess electrical energy, which is converted back into electrical energy by the voltage conversion unit when the photovoltaic receiving unit's power supply is insufficient, and then used by the lighting and communication unit and other units for emergency lighting and communication purposes. Background Technology

[0002] Early disaster relief efforts were severely hampered by the lack of lighting and communication equipment, making them both difficult and dangerous. Later, a towable device was developed that integrated photovoltaic power generation, batteries, lighting, and communication equipment into a single unit. However, roads were sometimes impassable during disasters, preventing the towable device from reaching the site. After improvements, the top-mounted equipment and electrical control equipment can be separately equipped with protective cases, allowing for airdrop delivery to various road conditions to provide emergency lighting and communication. The batteries are stored during normal operations, and can be immediately used when emergency rescue is needed by towing the device to the disaster area, improving disaster relief efficiency.

Summary of the Invention

[0015] This invention provides an intelligent mobile multifunctional photovoltaic energy storage monitoring device, characterized in that it includes a photovoltaic receiving unit, a folding control unit, a new energy battery unit, a voltage conversion unit, a control unit, a vertical frame unit, an extension unit, and a lighting and communication unit; the lighting and communication unit is connected to the extension unit and combined into a top-mounted device, fixed to the vertical frame unit, which has a quick-access port allowing the top-mounted device to be disassembled and assembled with the vertical frame unit; the photovoltaic receiving unit and the folding control unit are located on the side of the vertical frame unit; the new energy battery unit, the voltage conversion unit, and the control unit are located inside the vertical frame; the photovoltaic receiving unit, the folding control unit, the new energy battery unit, the voltage conversion unit, and the control unit are located inside the vertical frame unit; the photovoltaic receiving unit, the folding control unit, the new energy battery unit, the voltage conversion unit, and the control unit are located inside the vertical frame unit. The conversion unit and control unit are fixed on the three-dimensional frame unit; they are combined to form an electrical control device; the photovoltaic receiving unit and folding control unit, during operation, allow two or more layers of photovoltaic receiving units to unfold through the folding control unit, and then through manual adjustment or control unit control of direction, to maximize the output voltage of the photovoltaic receiving unit; the new energy battery unit can store excess electrical energy, and when the power provided by the photovoltaic receiving unit is insufficient, it is converted into electrical energy through the voltage conversion unit to power the lighting and communication unit and other units; the top equipment and electrical control equipment can be respectively equipped with top equipment protective boxes and electrical control equipment protective boxes, and can be transported by air to different road environments to provide emergency lighting and communication.

[0016] The first is the photovoltaic receiving unit: The photovoltaic receiving unit is a technology that uses the photovoltaic effect at the semiconductor interface to directly convert sunlight into electrical energy; its core is the solar cell, and multiple cells form a photovoltaic module. With the help of inverters and other equipment, direct current can be converted into usable alternating current; Photovoltaic power generation has the following characteristics: Clean and environmentally friendly: No pollutants are emitted during the power generation process, and no greenhouse gases are produced, which is environmentally friendly;

[0017] Renewable energy: Solar energy is an inexhaustible renewable energy source, not limited by resource distribution; Flexible installation: It can be installed in various scenarios such as rooftops, wastelands, and water surfaces, and is suitable for distributed and centralized power generation; Low maintenance cost: Photovoltaic modules have a long lifespan (generally 20-25 years), and daily maintenance is simple, requiring only regular cleaning and inspection;

[0018] Photovoltaic power generation is an important direction for global energy transition. With technological advancements, its costs are continuously decreasing and its efficiency is constantly improving, and its proportion in the energy structure is gradually expanding.

[0019] Secondly, there is the folding control unit: the folding control unit folds the photovoltaic panel; it is mainly designed according to its application scenario (such as portable mobility, temporary power supply, etc.), and the core is to reduce the storage volume while ensuring structural stability and power generation efficiency. Common folding methods include bi-fold, multi-segment folding, roll-up, and integrated folding bracket.

[0020] Foldable type: The photovoltaic panel is folded in half along the center line, similar to the opening and closing of a book. The two panels are connected by a hinge. When unfolded, it is flat. When folded, the thickness doubles but the area is halved, making it suitable for small, portable photovoltaic panels (such as those used for outdoor camping).

[0021] Multi-section folding photovoltaic systems consist of three or more panels connected sequentially by hinges, allowing them to fold segment by segment like an accordion. When unfolded, they form a large panel; when folded, they take on a long, narrow shape, facilitating transportation and storage. They are commonly found in small to medium-sized portable photovoltaic devices.

[0022] Roll-up type: This method is commonly used for flexible photovoltaic panels. The panel can be rolled up on a roller, similar to rolling up a carpet. The advantages are that it is small in size and light in weight after storage, making it suitable for scenarios that require frequent movement (such as RVs and outdoor operations), but it requires high strength of the panel material.

[0023] Integrated folding bracket: The photovoltaic panels and bracket are combined, and the bracket can be folded and stowed away, with the panels folding synchronously with the bracket. This method combines support and storage, and is suitable for temporary power stations that require quick installation and dismantling;

[0024] Different folding methods have their own focuses. Rigid photovoltaic panels are mostly folded in half or in multiple sections, while flexible photovoltaic panels are mainly rolled up. Both methods must avoid squeezing or abrading the solar cells during the folding process.

[0025] Thirdly, there are new energy battery units: New energy battery units refer to high-efficiency energy storage devices used in new energy fields (such as electric vehicles, energy storage systems, and renewable energy infrastructure). Their core function is to convert chemical energy into electrical energy, and they are characterized by being environmentally friendly, highly efficient, and recyclable. Common types include lithium-ion batteries, ternary lithium batteries, lithium iron phosphate batteries, and hydrogen fuel cells.

[0026] Lithium-ion batteries: currently the most widely used, with high energy density and long cycle life;

[0027] Ternary lithium batteries: high energy density, good low-temperature performance, commonly used in electric vehicles;

[0028] Lithium iron phosphate batteries: high safety, low cost, more cycle life, suitable for energy storage and commercial vehicles;

[0029] Sodium-ion batteries: abundant raw materials (sodium resources are readily available), low cost, good low-temperature performance, and slightly lower energy density than lithium batteries. They are suitable for energy storage, low-speed vehicles, and other scenarios, and are a potential alternative.

[0030] Hydrogen fuel cells generate electricity through the reaction of hydrogen and oxygen, with water as the emission. They offer long driving range and fast refueling, but are costly and have underdeveloped infrastructure, and are mostly used in commercial vehicles and specific fields.

[0031] Solid-state batteries: using solid electrolytes, they offer significantly improved safety and higher energy density, and represent an important direction for next-generation battery technology. They are currently in the early stages of research and development and industrialization.

[0032] New energy batteries are the core component of the new energy industry. Their performance (energy density, safety, cost, and lifespan) directly affects the development of related fields. Currently, the technology is iterating rapidly and is constantly moving towards greater efficiency, safety, and lower cost.

[0033] The fourth is the voltage conversion unit: a voltage conversion unit is an electronic device used to convert one voltage level to another. It is widely used in power systems, electronic equipment and other fields to ensure that different devices or circuits can work under the appropriate voltage. The types of voltage conversion units (4) include four major categories: DC-DC conversion unit, AC-AC conversion unit, AC-DC conversion unit and DC-AC conversion unit.

[0034] DC-DC converter: Converts one DC voltage to another, such as converting the 5V USB voltage in a mobile phone charger to the approximately 3.7V voltage required by the battery;

[0035] AC-AC conversion unit: mainly used to change the amplitude or frequency of AC voltage, commonly found in transformers (changing amplitude) and frequency converters (changing frequency and amplitude);

[0036] AC-DC conversion unit: Converts AC power to DC power. For example, a power adapter first converts AC power to DC power through a rectifier circuit, and then outputs a stable voltage through a voltage regulator circuit.

[0037] DC-AC conversion unit: also known as an inverter, it converts direct current (DC) into alternating current (AC). For example, in a solar power system, it converts the DC power stored in the battery into 220V AC power for household use.

[0038] The voltage conversion unit (4) has the following core functions: voltage conversion: to realize the conversion of different voltage levels to meet the power supply requirements of the equipment; voltage regulation: some conversion units have voltage regulation function to ensure that the output voltage is stable and is not affected by input voltage fluctuations or load changes; and isolation: some conversion units (such as DC-DC converters with isolation, transformers) can realize electrical isolation between input and output circuits, improving safety and anti-interference ability.

[0039] Fifthly, the control unit: after the photovoltaic receiving unit and the folding control unit generate a stable voltage output, it charges the new energy battery unit and the voltage conversion unit changes other output voltages; the control unit controls the extension unit to extend the lighting unit and communication unit, thereby increasing the lighting range and communication distance.

[0040] The sixth component is the extension unit: The extension unit includes the extension of the lighting unit and communication unit, thereby increasing the lighting range and communication distance. The extension unit uses a hydraulic / pneumatic drive (such as a lifting platform or hydraulic lift), based on Pascal's law: the hydraulic pump (or air pump) pressurizes the liquid (or gas), which pushes the piston in the cylinder to extend and retract, thereby driving the connected platform or boom to rise / fall. The control valve regulates the flow of liquid (or gas) to achieve precise height control and has a strong load capacity.

[0041] The seventh is the lighting and communication unit, which includes a lighting unit and a communication unit (82); the lighting unit includes various LED lighting fixtures such as ceiling lights, downlights, and spotlights, with a waterproof design to ensure uniform brightness and long lifespan of the LED beads; the communication unit commonly uses three categories of emergency communication equipment: satellite communication equipment and wireless self-organizing network equipment, which are subdivided as follows:

[0042] ① Satellite phone: It can make voice calls and transmit data through satellite links in remote areas, at sea, disaster areas and other places where conventional communication networks cannot cover. For example, Iridium phone is small and portable and can achieve communication around the world.

[0043] ② Satellite Portable Case: Small and lightweight, it can be quickly deployed for scenarios where local communication networks are interrupted or coverage is blind. It can connect directly to satellites, is not limited by geographical location, and can quickly establish a transmission channel and open a base station through a satellite link.

[0044] ③ Satellite communication vehicle: It adopts satellite, fiber optic and microwave as the main transmission means. It has the characteristics of reliable performance, high mobility and simple operation. It can provide 2 / 4G network communication coverage within a radius of 2 kilometers and support up to 256 users to make voice calls at the same time.

[0045] ④MESH wireless self-organizing network equipment: It adopts a distributed network architecture without a central self-organizing network, with same-frequency networking and multi-hop relay. All nodes can realize real-time interaction of multi-channel voice, data, images and other multimedia information under non-line-of-sight and random rapid movement conditions.

[0046] ⑤ Walkie-talkie: A two-way mobile communication tool that allows you to make calls without any network support and without incurring call charges. It is suitable for relatively fixed and frequent communication situations, such as Motorola walkie-talkies, which are sturdy, durable, and have a long communication range.

[0047] ⑥ Unmanned aerial vehicle (UAV) communication equipment includes communication reconnaissance UAVs: which can quickly fly to a designated location using a rocket-propelled launch device, carry a public network base station, restore network signal for mobile phones within a certain range, and also conduct disaster reconnaissance and transmit aerial images back in real time; and UAV emergency communication high-altitude base stations: which use tethered multi-rotor UAVs to deploy base station equipment at high altitudes, quickly and effectively establish communication networks for specific areas, ensure communication signal coverage within a certain range, and hover continuously for several hours.

[0048] ⑦ Portable Emergency Communication Handbag: Compact in appearance, with a signal coverage range of up to 400 meters and a standby time of 10 hours, it consists of a signal device, portable battery, antenna and matching bracket, etc., and is suitable for special support scenarios such as field operations, disaster relief, tunnels and wells.

[0049] ⑧ Ground-penetrating communication equipment: It can break through the limitations of traditional communication methods, has strong penetration power, ignores concrete rock layers and metal barriers, and the signal can reach 1,000 meters underground, covering complex scenarios such as tunnels, mines, and air-raid shelters. It has strong anti-interference ability, is easy to operate and can be deployed quickly.

[0050] ⑨ Small 4G / 5G base stations include macro base stations: coverage radius 1-30 kilometers, suitable for wide-area coverage, such as urban areas, rural areas, and highways, which can meet the communication needs of a large number of users; and micro base stations: coverage radius 0.1-1 kilometers, often used in urban hotspots, such as shopping malls, office buildings, and schools, which can specifically enhance the signal coverage and capacity of local areas.

[0051] The eighth type is the vertical frame unit: The vertical frame unit has photovoltaic receiving units and folding control units installed on its sides, with one or more sides. Each side can have one or more photovoltaic receiving units unfolded. Each side of the vertical frame unit has a fixed support at the bottom, which makes the vertical frame unit stable and balanced after unfolding.

[0052] The preferred embodiment is as follows: the top-mounted equipment includes an extension unit and a lighting and communication unit; the electrical control equipment includes a photovoltaic receiving unit, a folding control unit, a new energy battery unit, a voltage conversion unit, and a control unit, all fixed to a three-dimensional frame unit. The top-mounted equipment and electrical control equipment can be equipped with separate protective cases for the top-mounted equipment and the electrical control equipment, respectively, and can be airdropped to different road environments to provide emergency lighting and communication. The protective case for the top-mounted equipment has shock-absorbing foam inside to protect the top-mounted equipment, and a shock-absorbing base at the bottom to reduce the impact force when the protective case lands. A hook at the top allows it to be connected to a projectile rope from the aircraft, which is slowly released upon arrival at the site to ensure a safe landing. The protective case for the electrical control equipment also has shock-absorbing foam inside to protect the top-mounted equipment, and a shock-absorbing base at the bottom to reduce the impact force when the protective case lands. A hook at the top allows it to be connected to a projectile rope from the aircraft, which is slowly released upon arrival at the site to ensure a safe landing. The walls of both the protective cases for the top-mounted equipment and the electrical control equipment are modular and reusable.

[0053] The preferred embodiment is a lighting communication unit that allows multiple communication units in a multi-functional mobile photovoltaic energy storage monitoring device to be connected in series, forming a communication network. As long as one of them can communicate with the Internet, the other multi-functional mobile photovoltaic energy storage monitoring devices can also use the Internet.

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. 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. In one embodiment of the present invention, this example is an intelligent mobile multifunctional photovoltaic energy storage monitoring device, referring to the accompanying drawings.

The new energy battery unit 3 can store excess electrical energy. When the photovoltaic receiving unit 1 provides insufficient power, the voltage conversion unit 4 reverses the voltage and converts it into electrical energy for use by the lighting and communication unit 8 and other units. (See attached diagram.)

The advantages are that it is small in size and light in weight after storage, making it suitable for scenarios that require frequent movement (such as RVs and outdoor operations), but it requires high strength of the panel material.

[0097] Integrated folding bracket: The photovoltaic panels and bracket are combined, and the bracket can be folded and stowed away, with the panels folding synchronously with the bracket. This method combines support and storage, and is suitable for temporary power stations that require quick installation and dismantling;

[0098] Different folding methods have their own focuses. Rigid photovoltaic panels are mostly folded in half or in multiple sections, while flexible photovoltaic panels are mainly rolled up. Both methods must avoid squeezing or abrading the solar cells during the folding process.

[0099] Thirdly, there is the new energy battery unit 3: This refers to a high-efficiency energy storage device used in new energy fields (such as electric vehicles, energy storage systems, and renewable energy infrastructure). Its core function is to convert chemical energy into electrical energy, featuring environmental friendliness, high efficiency, and recyclability. (See attached document.) Figure 10 Common new energy battery cell types include lithium-ion batteries, ternary lithium batteries, lithium iron phosphate batteries, and hydrogen fuel cells.

[0100] Lithium-ion batteries: Currently the most widely used, with high energy density and long cycle life; lithium batteries refer to batteries that use lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution; Classification: primary lithium batteries: namely lithium metal batteries, using metallic lithium as the negative electrode active material; secondary lithium batteries: namely lithium-ion batteries, which can be repeatedly charged, including liquid lithium-ion batteries, polymer lithium-ion batteries and all-solid-state lithium-ion batteries.

[0101] Ternary lithium batteries: High energy density and good low-temperature performance, commonly used in electric vehicles; Ternary lithium batteries refer to lithium batteries that use ternary cathode materials such as lithium nickel cobalt manganese oxide (Li(NiCoMn)O2) or lithium nickel cobalt aluminum oxide; Working principle: An external power source provides energy, lithium ions (Li+) are extracted from the cathode material and move to the negative electrode through the electrolyte, while electrons (e-) flow out from the cathode, pass through the external circuit to the negative electrode, and maintain charge balance.

[0102] Lithium iron phosphate (LFP) batteries: High safety, low cost, and more cycle life, suitable for energy storage and commercial vehicles; LFP batteries are a type of lithium-ion battery. Working principle: During charging, lithium ions are extracted from the lithium iron phosphate material at the positive electrode, migrate through the electrolyte and separator to the negative electrode, where the negative electrode is in a lithium-rich state, and the lithium iron phosphate at the positive electrode is converted to iron phosphate. During discharging, lithium ions are extracted from the negative electrode, inserted into the positive electrode through the electrolyte, while electrons flow from the negative electrode to the positive electrode through an external circuit, forming an electric current to provide energy to electrical devices. A disadvantage is poor low-temperature performance.

[0103] Sodium-ion batteries: abundant raw materials (sodium resources are readily available), low cost, good low-temperature performance, and slightly lower energy density than lithium batteries. They are suitable for energy storage, low-speed vehicles, and other scenarios, and are a potential alternative.

[0104] Hydrogen fuel cells generate electricity through the reaction of hydrogen and oxygen, with water as the emission. They offer long driving range and fast refueling, but are costly and have underdeveloped infrastructure, and are mostly used in commercial vehicles and specific fields.

[0105] Solid-state batteries: using solid electrolytes, they offer significantly improved safety and higher energy density, and represent an important direction for next-generation battery technology. They are currently in the early stages of research and development and industrialization.

[0106] New energy batteries are the core component of the new energy industry. Their performance (energy density, safety, cost, and lifespan) directly affects the development of related fields. Currently, the technology is iterating rapidly and is constantly moving towards greater efficiency, safety, and lower cost.

[0109] AC-AC conversion unit: mainly used to change the amplitude or frequency of AC voltage, commonly found in transformers (changing amplitude) and frequency converters (changing frequency and amplitude);

[0110] AC-DC conversion unit: Converts AC power to DC power. For example, a power adapter first converts AC power to DC power through a rectifier circuit, and then outputs a stable voltage through a voltage regulator circuit.

[0111] DC-AC conversion unit: also known as an inverter, which can convert direct current into alternating current. For example, in a solar power generation system, the DC power stored in the battery is converted into 220V AC power for household use.

Common folding methods include bi-fold, multi-segment folding, roll-up, and integrated folding bracket. The folding type involves folding the photovoltaic panel along its center line, similar to opening and closing a book. The two panels are connected by a hinge. When unfolded, it is flat; when folded, its thickness doubles but its area is halved, making it suitable for small, portable photovoltaic panels (such as those used for outdoor camping). The multi-segment folding type consists of three or more panels connected sequentially by hinges, allowing it to fold segment by segment like an accordion. When unfolded, it forms a large panel; when folded, it takes on a long strip shape, facilitating transportation and storage. It is commonly found in small to medium-sized portable photovoltaic equipment. The roll-up type: This method is commonly used for flexible photovoltaic panels. The panel can be rolled up on a roll, similar to rolling up a carpet. The advantages are that it is small in size and light in weight after storage, making it suitable for scenarios that require frequent movement (such as RVs and outdoor operations), but it requires high strength of the panel material.

Both methods must avoid squeezing or abrading the solar cells during the folding process.
