Description

Technical Field

[0001] This invention relates to the field of energy storage technology, and more specifically, to an integrated device for energy harvesting, storage, and utilization. Background Technology

[0002] Currently, electrical equipment generally relies on cable laying for power transmission, but this model has many structural defects. 1. High construction complexity: Cable laying requires trench excavation (depth ≥ 0.7m with a sand protection layer of 1m), pipe sealing (diameter greater than 1.5 times that of the cable), and fireproofing of cable trays, among other procedures. In remote areas such as deserts and mountains, the costs of geological surveys and machinery transportation increase dramatically. For example, excavation in permafrost requires specialized equipment, and wind and sand erosion in deserts necessitates deeper burial, leading to a 30%–50% extension of the construction period.

[0003] 2. Significant maintenance difficulties and safety hazards: Directly buried cables are easily damaged by external forces (such as mechanical crushing and corrosive soil), making fault location difficult; failure of waterproofing at joints will cause short circuits (the error rate of waterproof box installation reaches 23%); although mineral-insulated cables are resistant to high temperatures, they have a large bending radius, complex laying process, and labor costs account for more than 40%.

[0004] 3. High cost of power grid coverage blind spots: Remote areas (such as border outposts and oil pipeline monitoring points) require dedicated lines to be laid, with a comprehensive cost of 50,000 to 80,000 yuan per kilometer of cable laying, and the voltage attenuation rate exceeds 20%, requiring additional voltage stabilization equipment.

[0005] Although new energy applications have been explored, the problem of long-term self-powered equipment has not yet been systematically solved. Taking solar power as an example, although existing solar monitoring systems can be disconnected from the grid, energy storage relies on lead-acid / lithium batteries (-40℃~60℃), and the capacity decays by more than 50% in high-altitude and cold regions. At the same time, it only supports low-power equipment and cannot drive industrial-grade loads.

[0006] In view of the above-mentioned shortcomings of existing technologies, there is an urgent need to design an integrated device for energy harvesting, storage and use to meet the needs of practical use. Summary of the Invention

[0007] In view of the shortcomings of the prior art, the purpose of this invention is to provide an integrated device for energy harvesting, storage and use.

[0008] An integrated device for energy harvesting, storage, and utilization according to the present invention includes: An energy input and storage mechanism, partially or wholly configured as a main support structure or auxiliary support structure of a structural support component forming device, is used to collect natural energy and store negative pressure energy through fluid drive. The actuator is capable of performing output actions under the drive of the negative pressure energy; The control mechanism includes multiple valves and a controller, the controller being signal-connected to the multiple valves respectively, and the multiple valves being configured on a first fluid pipeline of the energy input and storage mechanism and / or configured on a second fluid pipeline between the energy input and storage mechanism and the actuator.

[0009] Preferably, the energy input and storage mechanism includes an energy harvesting component, a liquid storage container, a fluid drive component, and a negative pressure energy storage component; the energy harvested by the energy harvesting component is used to drive the fluid drive component, and the fluid drive component can pump the fluid in the liquid storage container into the negative pressure energy storage component to realize the storage of negative pressure energy.

[0010] Preferably, the energy harvesting component harvests the natural energy, which includes at least one of solar energy, wind energy, hydropower, tidal energy, wave energy, geothermal energy, biomass energy, and ocean thermal energy.

[0011] Preferably, the fluid drive assembly takes any of the following forms: The fluid drive assembly includes a pump body and a first motor. The first motor is driven and connected to the pump body. The inlet of the pump body is connected to the liquid storage container, and the outlet of the pump body is connected to the negative pressure energy storage assembly. The negative pressure energy storage assembly is equipped with a negative pressure chamber. When the pump body is running, it can pump the fluid in the liquid storage container into the negative pressure energy storage assembly, thereby increasing the volume of the negative pressure chamber and realizing the storage of negative pressure energy. The fluid drive assembly includes a rotating shaft and a second motor connected to the rotating shaft. The second motor can drive the rotating shaft to rotate, thereby enabling the flow to be drawn into the negative pressure energy storage assembly and simultaneously increasing the volume of the negative pressure chamber to achieve the storage of negative pressure energy. The fluid drive assembly is driven by a phase change material.

[0012] Preferably, the negative pressure energy storage component stores or releases the negative pressure energy through translation or rotation.

[0013] Preferably, the negative pressure energy storage component adopts any of the following structures: The negative pressure energy storage component includes a linkage, a first cylinder and a second cylinder. The linkage is equipped with a first piston and a second piston at its two ends. The first piston extends into the interior of the first cylinder and forms a fluid cavity with the first cylinder. The second cylinder extends into the interior of the second cylinder and forms a negative pressure cavity with the second cylinder. The fluid cavity is connected to the outlet of the pump body. The negative pressure energy storage component includes a rope, a first cylinder, and a second cylinder. One end of the first rope is connected to a first piston, which extends into the interior of the first cylinder and forms a fluid cavity with the first cylinder. The other end of the first rope is wound around a rotating shaft. One end of the second rope is connected to a second piston, which extends into the interior of the second cylinder and forms a negative pressure cavity with the second cylinder. The other end of the second rope is wound around the rotating shaft. The fluid cavity is connected to the liquid storage container through the first fluid pipeline. When the second motor drives the rotating shaft to rotate, both ropes are wound around the rotating shaft and become shorter, thereby driving the first piston and the second piston to move respectively, and causing the volume of both the fluid cavity and the negative pressure cavity to increase. The fluid in the liquid storage container is drawn into the fluid cavity. The negative pressure energy storage component includes a rotating plate, a fixed plate, and a housing. The fixed plate is fixed inside the housing, and the rotating plate is rotatably disposed inside the housing, forming a fluid cavity and a negative pressure cavity with the fixed plate. When fluid enters the fluid cavity, it drives the rotating plate to rotate, thereby increasing the size of the negative pressure cavity. When the fluid cavity is connected to the actuator, under the influence of external atmospheric pressure, the negative pressure cavity can drive the rotating plate to rotate, thereby allowing the fluid in the fluid cavity to enter the actuator and realize the execution of the output action.

[0014] Preferably, the control mechanism includes a charging valve and an output valve, wherein the charging valve is disposed on the first fluid pipeline and the output valve is disposed on the second fluid pipeline.

[0015] Preferably, the control mechanism further includes a control valve, and the actuation end mechanism includes multiple actuation devices, with the control valve configured between each actuation device and the second fluid pipeline.

[0016] Preferably, the structural support member adopts a cylindrical structure.

[0017] Preferably, the structural support is disposed in a building, and the structural support is disposed at at least one location among the roof, walls, and ground of the building.

[0018] Compared with the prior art, the present invention has the following beneficial effects: This invention, by configuring an energy input and storage mechanism, an execution mechanism, and a control mechanism, can store negative pressure energy by collecting natural energy and release it at any time when needed, achieving energy self-sufficiency. It eliminates the need for power supply through laying cables, solving the problems of high construction complexity, maintenance difficulty and prominent safety hazards, high cost in grid coverage blind spots, and severe battery energy degradation in existing technologies. It is simple to operate, convenient to use, green and environmentally friendly, and highly practical. Attached Figure Description

Detailed Implementation

[0021] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0022] Example 1: This invention provides an integrated device for energy harvesting, storage, and utilization, comprising an energy input and storage mechanism, an execution end mechanism 300, and a control mechanism. The energy input and storage mechanism is used to harvest natural energy and store negative pressure energy through fluid drive. Part or all of the energy input and storage mechanism is configured as the main support structure or auxiliary support structure of the structural support component forming device. The execution end mechanism 300 can perform output actions under the drive of negative pressure energy. The control mechanism includes multiple valves and a controller. The controller is electrically connected to the multiple valves. The multiple valves are configured on the first fluid pipeline 001 of the energy input and storage mechanism and / or on the second fluid pipeline 002 between the energy input and storage mechanism and the execution end mechanism 300. The controller controls the opening and closing of the fluid pipeline by controlling the valves, thereby realizing the execution of the output action. This invention highly integrates the drive structure and energy storage structure. The structural support components are preferably cylindrical, and to enhance support strength, suitable materials can be selected for their fabrication. These structural support components serve as the main or auxiliary support structures for the workshop building, achieving a "structure as energy storage" integrated structure. This allows for large-scale system expansion, and the negative pressure energy storage elements can be connected in parallel to meet the high energy density and redundancy requirements of high-power equipment. Simultaneously, the energy input and storage mechanisms are powered by natural energy sources, eliminating reliance on traditional electricity. The drive pump can be charged via photothermal conversion, air temperature difference, or wave energy, enabling all-weather green operation.

[0023] It should be noted that natural energy can take many forms, including solar energy, thermal energy, wind energy, hydropower (rivers, waterfalls, etc.), tidal energy (the mechanical energy of ocean tides), wave energy (the kinetic energy of ocean waves), geothermal energy (the thermal energy of the Earth's interior), biomass energy (plants, agricultural and forestry waste, animal manure, etc.), and ocean thermal energy (ocean temperature difference power generation), etc. The appropriate form can be selected flexibly according to the specific application scenario of the device.

[0024] like Figure 1 As shown, the energy input and storage mechanism includes an energy harvesting component, a liquid storage container 101, a fluid drive component 102, and a negative pressure energy storage component 103. The energy harvesting component harvests natural energy, and the energy harvested by the energy harvesting component is used to drive the fluid drive component 102. The fluid drive component 102 includes a pump body and a first motor. The first motor can drive the pump body to run. The inlet of the pump body is connected to the liquid storage container 101, and the outlet of the pump body is connected to the negative pressure energy storage component 103. The negative pressure energy storage component 103 is equipped with a negative pressure chamber 10321. When the pump body runs, it can pump the fluid in the liquid storage container 101 into the negative pressure energy storage component 103, thereby increasing the volume of the negative pressure chamber 10321 and realizing the storage of negative pressure energy.

[0025] like Figure 1 As shown, the negative pressure energy storage component 103 includes a linkage 1033, a first cylinder 1031, and a second cylinder 1032. The two ends of the linkage 1033 are respectively equipped with a first piston 10331 and a second piston 10332. The linkage 1033 is preferably a rod-shaped structure. The first piston 10331 extends into the interior of the first cylinder 1031 and forms a fluid cavity 10311 with the first cylinder 1031. The second cylinder 1032 extends into the interior of the second cylinder 1032 and forms a negative pressure cavity 10321 with the second cylinder 1032. The fluid cavity 10311 is connected to the outlet of the pump body through a first fluid pipe 001, and the fluid cavity 10311 is connected to the actuator 300 through a second fluid pipe 002. When the pump is running, it pumps fluid from the storage container 101 into the fluid chamber 10311. The fluid chamber 10311 expands in volume, pushing the linkage 1033 to move. The linkage 1033 then drives the second piston 10332 to move synchronously. At this time, the negative pressure chamber 10321 expands in volume, thus storing negative pressure energy. When the actuator 300 needs to perform an output action, under the influence of external atmospheric pressure, the negative pressure chamber 10321 drives the second piston 10332 to move, which in turn drives the first piston 10331 to move synchronously. This allows the fluid in the fluid chamber 10311 to be pushed into the actuator 300, achieving the corresponding output action.

[0026] like Figure 1As shown, the control mechanism includes a charging valve 201, an output valve 202, and a regulating valve 203. The charging valve 201 is configured on the first fluid pipeline 001, and the output valve 202 is configured on the second fluid pipeline 002. The controller can control the opening degree of the charging valve 201, the output valve 202, and the regulating valve 203 respectively, thereby realizing the control of the flow of fluid pipelines.

[0027] The actuator 300 includes multiple actuators 301. Each actuator 301 is connected to the fluid chamber 10311 via a second fluid pipeline 002. A control valve 203 is configured on the second fluid pipeline 002. By controlling the on / off state or the opening degree of the control valve 203, fluid driving power can be provided to one or more actuators 301.

[0028] In this embodiment, the natural energy source is solar energy, and the energy harvesting component includes a solar cell 104, such as... Figure 3 As shown, solar cells 104 directly convert light energy into electrical energy. In practical applications, multiple solar cells 104 can be connected in series or in parallel to form a solar cell array, which can achieve high power output. This method has the advantages of long life and no pollution.

[0029] Furthermore, the first cylinder 1031 and the second cylinder 1032 are arranged side by side as the main support structure or auxiliary support structure of the structural support member forming device for the building roof, ground and / or walls, such as... Figure 3 , Figure 4 As shown, the structure adopts the linkage 1033. The linkage 1033 can extend and retract in the cylinder. The space for the linkage 1033 to move can be designed during the building design, or the linkage 1033 can extend to the outside of the building when it moves, so as to avoid interference when the linkage 1033 moves. Machine tools, robots and other execution devices 301 are arranged inside the building. The negative pressure energy storage component 103 can drive the generator to generate electricity to power each execution device 301; or the execution of the execution device 301 can be achieved by direct fluid drive.

[0030] In practical applications, the actuator 300 is arranged inside and / or outside the building. The walls, roof and / or ground of the building can be independently supported by the cylinder in the negative pressure energy storage component 103 through rigid design. The cylinders can be detachably connected by suitable mechanical structures such as metal connectors and adapters, or by non-detachable connection methods such as bolt fastening and welding. In some areas with special requirements, the walls of the building can be made of reinforced concrete or other building materials. A space is reserved in the middle of the wall to accommodate the negative pressure energy storage component 103. The negative pressure energy storage component 103 can be connected with the building materials of the wall to form an integrated structure, which together are used to support the building to meet the actual strength requirements.

[0031] This invention breaks geographical constraints by employing multiple natural energy sources, adapting to scenarios such as high radiation in deserts, strong winds in plateaus, and thermal gradients in permafrost. It avoids the earthwork required for cable laying and achieves breakthroughs in dynamic energy management. It can incorporate AI power allocation algorithms to switch power supply modes based on equipment load priority, such as prioritizing monitoring equipment, and can be comprehensively controlled through control output valve 202 and regulating valve 203. Simultaneously, negative pressure energy storage is less affected by temperature and external environment, enabling stable power supply. Therefore, the self-powered natural energy device proposed in this invention fundamentally avoids the complexities, environmental dependence, and high maintenance costs of cable laying construction. Through a closed-loop technology of multi-source acquisition, intelligent allocation, and industrial-grade output, it provides power solutions for remote areas, mobile devices, and emergency scenarios, filling the technological gap in existing new energy power supply systems in terms of wide power range adaptability and robustness in extreme environments.

[0032] It should be noted that, in the specific implementation process of natural energy harvesting, various natural energy sources can be implemented in the following ways: Solar power generation: Photovoltaic power generation is preferred: silicon-based semiconductor materials / thin films directly convert light energy into electrical energy.

[0033] Wind power generation: including onshore wind power and offshore wind power, is an existing technology and will not be elaborated here.

[0034] Hydropower can be generated using methods such as dam-type, diversion-type, and hybrid methods, and it depends on the head difference of the water.

[0035] Tidal and wave energy generation: Tidal power station: The sea barrier dam has a two-way turbine, which can be implemented using the model of the French Rance tidal power station.

[0036] Wave energy: It is achieved by water wave oscillation and is an existing technology, so it will not be discussed further here.

[0037] Ocean thermal power generation: Utilizing the temperature difference between the surface seawater (26°C+) and the deep seawater (4°C) to drive the Rankine cycle, for example, the 1MW pilot power plant in Hawaii.

[0038] Geothermal power generation: using geothermal energy to directly drive a steam turbine.

[0039] Biomass power generation: direct combustion power generation: straw / garbage incineration boilers, or gasification power generation, biomass-generated biogas drives gas turbines.

[0040] Example 2: The difference between this embodiment and Embodiment 1 is that the negative pressure energy storage component 103 includes a rope 1034, a first cylinder 1031, and a second cylinder 1032, as follows: Figure 2As shown, the fluid drive assembly 102 includes a rotating shaft 1021 and a second motor 1022 drivenly connected to the rotating shaft 1021. One end of a first rope 1034 is connected to a first piston 10331, which extends into the interior of a first cylinder 1031 and forms a fluid cavity 10311 with the first cylinder 1031. The other end of the first rope 1034 is wound around the rotating shaft 1021. One end of a second rope 1034 is connected to a second piston 10332, which extends into the interior of a second cylinder 1032 and forms a negative pressure cavity 10321 with the second cylinder 1032. The other end of the second rope 1034 is wound around the rotating shaft 1021. On 021, the fluid chamber 10311 is connected to the liquid storage container 101 through the first fluid pipeline 001. The liquid storage container 101 contains fluid. When the second motor 1022 drives the rotating shaft 1021 to rotate, the two ropes 1034 follow the rotation of the rotating shaft 1021 and are wound around it, so that the two ropes 1034 become shorter, thereby driving the first piston 10331 and the second piston 10332 to move in the first cylinder 1031 and the second cylinder 1032 respectively. This causes the volumes of the fluid chamber 10311 and the negative pressure chamber 10321 to increase. The fluid in the liquid storage container 101 is drawn into the fluid chamber 10311, and a negative pressure is formed in the negative pressure chamber 10321 to store negative pressure energy.

[0041] In this embodiment, the first cylinder 1031 and the second cylinder 1032 are arranged side by side as the main support structure or auxiliary support structure of the structural support member forming device for the building roof, ground and / or walls, such as Figure 5 , Figure 6 As shown, the interior of the building is equipped with machine tools, robots and other execution devices 301. The negative pressure energy storage component 103 can drive a generator to generate electricity to power each execution device 301; or the execution devices 301 can be driven directly to perform their actions.

[0042] Example 3: The difference between this embodiment and Embodiment 1 is that the negative pressure energy storage component 103 includes a rotating plate 1035, a fixed plate 1036, and a housing 1037, as follows: Figure 8As shown, the fixed plate 1036 is fixed inside the housing 1037, and the rotating plate 1035 is rotatably disposed inside the housing 1037, forming a fluid cavity 10311 and a negative pressure cavity 10321 between the rotating plate 1035 and the fixed plate 1036. Both the fluid cavity 10311 and the negative pressure cavity 10321 are sealed chambers. The rotating plate 1035 has a rotating plate shaft 10351 disposed in the middle, and both ends of the rotating plate shaft 10351 are fixed on the housing 1037. The rotating plate 1035 can rotate around the rotating plate shaft 10351. When fluid enters the fluid chamber 10311, it drives the rotating plate 1035 to rotate, thereby increasing the size of the negative pressure chamber 10321. When the fluid chamber 10311 is connected to the actuator 300, under the influence of external atmospheric pressure, the negative pressure chamber 10321 can drive the rotating plate 1035 to rotate, thereby allowing the fluid in the fluid chamber 10311 to enter the actuator 300 to execute the output action.

[0043] Example 4: The difference between this embodiment and Embodiment 1 is that the fluid drive component 102 is driven by a phase change material 1038, such as... Figure 9 As shown, the energy driving form of the fluid drive component 102 is a phase change material energy mode. The fluid in the fluid cavity 10311 is driven by the phase change material 1038, which is disposed in the negative pressure cavity 10321. The phase change material 1038 can be implemented by means of electric heating, etc. When the phase change material 1038 is heated, its volume expands, pushing the piston towards the fluid cavity 10311, thereby pushing the fluid in the fluid cavity 10311 into the actuator 301 to realize the operation of the actuator 301. When the phase change material 1038 is not heated, its volume decreases, creating a vacuum in the negative pressure cavity 10321. At this time, fluid can be drawn into the fluid cavity 10311, and the output action of the actuator 301 is realized through the reciprocating motion of the piston.

[0044] It should be noted that the work done in this embodiment is flexible and controllable, and each negative pressure energy storage component 103 can be controlled independently, making the entire system modular and each component independently controllable, resulting in a simpler structure.

[0045] Example 5: This embodiment is a preferred example of Embodiment 1. In this embodiment, the execution of the output action of the actuator 300 includes various forms, such as realizing both the feed action and the retraction action. Figure 7As shown, the first cylinder 1031 is also equipped with an auxiliary fluid chamber 10312. The auxiliary fluid chamber 10312 is separated from the fluid chamber 10311 by the first piston 10331. The actuator 301 is equipped with a first actuator chamber 3011 and a second actuator chamber 3012. The auxiliary fluid chamber 10312 is connected to the liquid storage container 101 through a third fluid pipeline 003. A return valve 204 is installed on the third fluid pipeline 003. The auxiliary fluid chamber 10312 is connected to the second actuator chamber 3012 through a fourth fluid pipeline 004. The first actuator chamber 3011 is connected to the fluid chamber 10311 through a second fluid pipeline 002. The output valve 202 can simultaneously control the second fluid pipeline 002 and the fourth fluid pipeline 004.

[0046] When negative pressure energy storage is required, the charging valve 201 and the return valve 204 are opened. The pump body pumps the fluid from the storage container 101 into the fluid chamber 10311 through the first fluid pipeline 001. At this time, the volume of the fluid chamber 10311 increases, while the volume of the auxiliary fluid chamber 10312 decreases. The fluid in the auxiliary fluid chamber 10312 flows back to the storage container 101 through the third fluid pipeline 003. Simultaneously, the volume of the negative pressure chamber 10321 increases, thus achieving negative pressure energy storage. It should be noted that if the device 301 needs to perform a feeding action during negative pressure energy storage, the return valve 204 needs to be closed, and the output valve 202 controlling the fourth fluid pipeline 004 needs to be opened. The fluid in the auxiliary fluid chamber 10312 flows into the second execution chamber 3012 through the fourth fluid pipeline 004 to achieve the feeding action.

[0047] When negative pressure energy release is required, the output valve 202 on the second fluid pipeline 002 is opened, the return valve 204 is opened, and the output valve 202 on the fourth fluid pipeline 004 is closed. Driven by the external atmospheric pressure, the second piston 10332 moves toward the negative pressure chamber 10321, thereby reducing the volume of the fluid chamber 10311. The fluid in the fluid chamber 10311 enters the first execution chamber 3011 through the second fluid pipeline 002 to realize the feeding action of the execution device 301.

[0048] Taking Example 1 as an example, the working principle of the present invention is as follows: When storing negative pressure energy, the controller first controls the charging valve 201 on the corresponding negative pressure energy storage component 103 to open and the output valve 202 to close. At the same time, the pneumatic first motor drives the pump body to run. At this time, the fluid in the storage container 101 is pumped into the corresponding fluid chamber 10311. The volume of the fluid chamber 10311 increases, which in turn drives the linkage 1033 to move. The linkage 1033 drives the second piston 10332 to move synchronously. At this time, the volume of the negative pressure chamber 10321 increases, thereby realizing the storage of negative pressure energy.

[0049] When negative pressure energy needs to be released, the output valve 202 is opened and the control valve 203 connected to the corresponding actuator 301 is opened. Driven by the external atmospheric pressure, the linkage 1033 pushes the second piston 10332 to move in the direction where the volume of the negative pressure chamber 10321 decreases, thereby driving the first piston 10331 to push the fluid in the fluid chamber 10311 through the second fluid pipeline 002 into the actuator 301, thereby driving the actuator 301.
