Description

Technical Field

[0001] This utility model relates to the field of microgrid energy storage technology, specifically to a protection device for microgrid energy storage in mountainous areas. Background Technology

[0002] Mountain microgrids, as an important solution to the power supply problem in remote mountainous areas, achieve energy self-sufficiency and flexible dispatch by integrating distributed renewable energy sources (such as solar and wind power) with energy storage systems. However, the complex terrain and climate conditions in mountainous areas pose severe challenges to the stable operation of microgrids.

[0003] Existing energy storage protection devices for mountain microgrids focus on energy storage system charge and discharge control, fault isolation, and energy management. Their core working principle is as follows: A bidirectional energy flow between the energy storage battery and the microgrid is achieved through a power conversion system (PCS). Based on the microgrid load demand and distributed energy generation status, the charging and discharging power of the energy storage system is dynamically adjusted to balance supply and demand. Using protective components such as circuit breakers and fuses, faulty lines are quickly disconnected upon detection of short circuits, overloads, or other line faults to prevent the fault from escalating and endangering the stable operation of the microgrid. The energy management system (EMS) monitors the microgrid's operating status in real time, including information such as distributed energy generation power, remaining energy storage capacity, and load demand. Based on preset scheduling strategies, the charging and discharging plan of the energy storage system is optimized, thereby improving the economy and reliability of the microgrid.

[0004] On the one hand, lightning strikes, natural disasters, and line faults can easily cause power outages to the protection devices, and the cooling devices will stop simultaneously. If the equipment was operating at a high load before the power outage, the residual heat cannot be dissipated, which will cause the component temperature to rise sharply, accelerate aging, or even damage it, affecting the lifespan of the energy storage system, the reliability of startup, and increasing operation and maintenance costs. On the other hand, as an important distributed energy source for mountain microgrids, existing equipment has poor power generation stability and safety when dealing with complex wind conditions. It cannot effectively control the fan speed, and the speed will rise out of control when encountering strong winds, exceeding the design load of the transmission system and generator, causing failures such as bearing wear and gear breakage, shortening the equipment lifespan and affecting the stable operation of the microgrid. Moreover, the wind conditions vary greatly in different mountainous areas, and the existing equipment is not adaptable to the scenarios and cannot meet the actual needs. Summary of the Invention

[0005] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a protection device for energy storage in mountain microgrids. Through mechanical linkage adjustment components, the fan blade speed is adaptively controlled to avoid overload in strong winds and inefficiency in light winds, ensuring stable power output from the generator. At the same time, it enables independent power generation, reducing dependence on the external power grid and meeting the independent operation requirements of mountain microgrids. The nano-ceramic coating on the fan blades and the nano-silica coating on the dustproof net solve the problems of wind and sand abrasion and dust adsorption in mountainous areas, respectively. The heat dissipation components combine efficient heat dissipation with rain and dust protection, making it fully adaptable to the harsh mountain environment and reducing equipment failure and maintenance costs.

[0010] In one alternative embodiment, the surface of the fan blades is uniformly coated with a protective composite coating.

[0011] In one optional embodiment, the fixed base has a through hole, and the rotating rod is rotatably connected to the fixed base through the through hole.

[0012] In one optional embodiment, the heat dissipation assembly includes heat dissipation fans fixedly connected to both ends of the energy storage installation box, a top plate fixedly connected to the energy storage installation box, heat dissipation and dust prevention nets symmetrically arranged on the top plate fixedly connected to the top plate, an adjustment frame fixedly connected to the energy storage installation box, and a shielding plate fixedly connected to the heat dissipation and dust prevention net.

[0013] In one optional embodiment, the surface of the heat dissipation and dustproof mesh is uniformly coated with a composite coating.

[0022] Please refer to Figure 1-5The protection device for energy storage in mountain microgrids includes an energy storage installation box 1, a cabinet door 4 rotatably connected to the energy storage installation box 1, a fixed base 21 fixedly connected to the energy storage installation box 1, an adjustment component fixedly connected to the fixed base 21, a connecting ring 210 installed on the adjustment component, a wind turbine component installed on the connecting ring 210, a fan blade 215 installed on the wind turbine component, a generator 22 fixedly connected to the fixed base 21, a battery 216 fixedly connected to the energy storage installation box 1, and heat dissipation components installed at both ends of the energy storage installation box 1. The fan blades 215 on the wind turbine rotate under the influence of the wind, causing the regulating component to move closer to or further away from the fan blades 215 along with the wind regulating connecting ring 210, thus controlling the rotation speed of the fan blades 215. The rotation of the fan blades 215, in conjunction with the generator 22, charges the battery 216. The heat dissipation component dissipates heat from the components inside the energy storage installation box 1, which provides a closed protective space for the internal components. The cabinet door 4 facilitates installation and maintenance. The mounting base 21 ensures the stable installation of the regulating component and the generator 22. The regulating component achieves precise control of the fan blade speed 215. The wind turbine and the generator 22 work together to generate electricity efficiently. The battery 216 stores emergency power. The heat dissipation component ensures the components operate at low temperatures. All components work together to achieve the integration of "power generation, energy storage, protection, and heat dissipation," significantly improving the adaptability to mountainous environments.

[0023] In a preferred embodiment of this utility model, the adjusting assembly includes a rotating rod 23 fixedly connected to the generator 22, several sliding rods 24 arranged in a circular array with one end fixedly connected to the rotating rod 23, a fixed block 211 slidably connected to the rotating rod 23, connecting rods 27 symmetrically arranged and rotatably connected to the fixed block 211 with one end rotatably connected, a rotating rod 26 rotatably connected to the other end of the connecting rod 27, a gravity ball 28 fixedly connected to one end of the rotating rod 26, a rotating block 25 fixedly connected to the rotating rod 23, a rotating shaft 213 fixedly connected to the rotating block 25, a spring 29 fixedly connected to the rotating block 25, and a circular array of rods rotatably connected to the connecting ring 210 with one end rotatably connected. Several fixed rods 214 and a wind turbine component installed at the other end of the fixed rods 214 are provided. A connecting ring 210 is slidably connected to a rotating shaft 213. The connecting ring 210 is fixedly connected to the other end of a sliding rod 24. The other end of a rotating rod 26 is rotatably connected to a rotating block 25. The rotating rod 23 and the sliding rod 24 provide stable support and sliding guidance for the connecting ring 210. The linkage structure of the fixed block 211, the connecting rod 27 and the rotating rod 26 can be automatically adjusted according to the wind force. The gravity ball 28 uses centrifugal force to achieve self-adaptive adjustment without electricity. The spring 29 ensures smooth component reset. The fixed rods 214 ensure accurate power transmission. The overall structure requires no manual intervention and is suitable for unattended mountainous scenarios.

[0024] In a preferred embodiment of this utility model, the wind power component includes a plurality of rotating rods 212 arranged in a circular array and fixedly connected to the rotating shaft 213, and fan blades 215 rotatably connected to the rotating rods 212. The other end of the fixed rod 214 is rotatably connected to the fan blades 215. The circular array of rotating rods 212 ensures that the fan blades 215 are subjected to uniform force. The rotatable connection design ensures that the angle of the fan blades 215 can be flexibly adjusted. The fixed rod 214 is firmly connected to the fan blades 215, ensuring that the speed adjustment command is accurately executed. The multi-blade structure improves the wind energy capture efficiency and is suitable for different wind speed conditions in mountainous areas.

[0025] In a preferred embodiment of this utility model, when the fixed block 211 moves closer to or further away from the rotating block 25, the angle between the connecting rod 27 and the first rotating rod 26 will increase or decrease, the connecting ring 210 will move closer to or further away from the fan blade 215, the connecting ring 210 will cause the angle between the fixed rod 214 and the fan blade 215 to increase or decrease, the fixed rod 214 will cause the angle between the fan blade 215 and the second rotating rod 212 to increase or decrease, and the rotational speed of the fan blade 215 will increase or decrease. The movement of the fixed block 211 is converted into precise adjustment of the angle of the fan blade 215 through multi-level linkage, so as to achieve a smooth change in rotational speed, avoid sudden changes in rotational speed from impacting the generator 22 and transmission components, reduce equipment wear, and at the same time stabilize the rotational speed to ensure stable power generation parameters and improve the efficiency of energy storage and utilization.

[0026] In a preferred embodiment of this utility model, the surface of the fan blade 215 is uniformly coated with a protective composite coating [nano-ceramic composite coating]. The nano-ceramic composite coating on the surface of the fan blade 215 has high hardness and wear resistance, and can resist the impact of mountain wind and sand and the erosion of rainwater. It avoids the increase of wind resistance caused by the rough surface of the fan blade 215, maintains good aerodynamic performance for a long time, and improves the wind energy utilization efficiency and the service life of the fan blade 215.

[0027] In a preferred embodiment of this utility model, a through hole is provided on the fixed base 21, and the rotating rod 23 is rotatably connected to the fixed base 21 through the through hole. The through hole on the fixed base 21 provides a stable rotation space for the rotating rod 23, ensuring that the rotating rod 23 can operate flexibly and is installed firmly, avoiding deviation or jamming caused by wind impact in mountainous areas, ensuring stable operation of the generator 22, and improving the overall transmission reliability of the device.

[0028] Please refer to Figure 5In a preferred embodiment of this utility model, the heat dissipation component includes a heat dissipation fan 31 fixedly connected to both ends of the energy storage installation box 1, a top plate 32 fixedly connected to the energy storage installation box 1, a heat dissipation and dustproof net 33 symmetrically arranged on the top plate 32 fixedly connected to the top plate 32, an adjustment bracket 34 fixedly connected to the energy storage installation box 1, and a shielding plate 35 fixedly connected to the heat dissipation and dustproof net 33. The heat dissipation fan 31 efficiently dissipates heat from the box, preventing components from being damaged by high temperature; the heat dissipation and dustproof net 33 blocks dust from entering the mountainous area, the shielding plate 35 prevents rainwater from seeping in, and the top plate 32 provides installation support for each component, realizing an integrated design of heat dissipation, dustproofing, and rainproofing, adapting to the complex mountainous environment.

[0029] In a preferred embodiment of this utility model, the surface of the heat dissipation and dustproof mesh 33 is uniformly coated with a composite coating [nano-silica composite coating]. The nano-silica composite coating on the surface of the heat dissipation and dustproof mesh 33 has low surface energy and antistatic properties, which can reduce dust adsorption, avoid mesh blockage and affect heat dissipation effect. At the same time, the coating is resistant to rain erosion and wear, extending the service life of the dustproof mesh and reducing the maintenance frequency and cost in mountainous areas.

[0030] When working, first open the cabinet door 4 of the energy storage installation box 1, install the energy storage related components into the box, and then close the cabinet door 4. The fixed base 21 provides a stable installation foundation for the adjustment components and the generator 22.

[0031] The wind in the mountainous area acts on the fan blade 215, causing the fan blade 215 to rotate around the rotating rod 212. Through the rotating shaft 213 and the rotating rod 23, the generator 22 is driven to operate, converting wind energy into electrical energy and storing it in the battery 216 to provide power support for the operation of the device. When the wind force changes, the adjustment component responds automatically: When the wind force increases, the gravity ball 28 is driven by centrifugal force to rotate the first rotating rod 26, which increases the angle between the connecting rod 27 and the first rotating rod 26, pushing the fixed block 211 away from the rotating block 25 along the rotating rod 23. Through the sliding rod 24, the connecting ring 210 moves closer to the fan blade 215 along the rotating shaft 213, and the angle between the fixed rod 214 and the fan blade 215 decreases, which in turn decreases the angle between the fan blade 215 and the second rotating rod 212, and the fan blade 215 speed decreases; When the wind force decreases, the spring 29 returns to its original position and pulls the fixed block 211 closer to the rotating block 25, the angle between the connecting rod 27 and the first rotating rod 26 decreases, the connecting ring 210 moves away from the fan blade 215, the fixed rod 214 pushes the angle between the fan blade 215 and the second rotating rod 212 to increase, and the fan blade 215 speed increases, thus achieving adaptive speed adjustment.

[0032] The heat dissipation components at both ends of the energy storage installation box 1 work synchronously: the cooling fan 31 accelerates the air circulation inside and outside the box, dissipating the heat generated by the components inside the box; the heat dissipation and dustproof net 33 on the top plate 32 blocks mountain dust from entering, and the shield 35 protects against rain. The nano-ceramic composite coating on the surface of the fan blade 215 enhances wear resistance and corrosion resistance, and the nano-silica composite coating on the surface of the heat dissipation and dustproof net 33 reduces dust adsorption, together improving the durability of the device.

[0033] Although only certain components and embodiments of this application have been illustrated and described, many modifications and alterations will be apparent to those skilled in the art without actually departing from the scope and spirit of the claims, such as variations in the size, dimensions, structure, shape and proportion of the various elements, installation arrangement, material use, color, orientation, etc.

[0034] Finally, it should be noted that the above embodiments are only preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
