Description

Technical Field

[0001] This application relates to the field of energy storage equipment loading, unloading and mobility technology, and in particular to a self-loading and unloading energy storage container. Background Technology

[0002] Against the backdrop of energy structure transformation and the upgrading of power security requirements, energy storage containers, as mobile energy hubs, have become core equipment supporting emergency power supply, new energy consumption, and power supply in special scenarios. When natural disasters cause power outages, they can quickly provide emergency power to critical facilities such as hospitals and communication base stations. In scenarios such as engineering construction and large-scale temporary events, they can flexibly supply on-site power. Among these, the mobility and ease of loading and unloading of energy storage containers are among their core functional requirements. In emergency response, field operations, or temporary power supply scenarios, the equipment needs to be quickly deployed to the target location and efficiently loaded and unloaded to adapt to complex environments.

[0003] In related technologies, after the energy storage container is transported to the target location, the lifting mechanism extends outward and lowers the outriggers to the ground. The energy storage container is stably supported by the leveled outriggers and is in a fixed state. The extension and retraction of each outrigger is dynamically adjusted in real time to ensure that the energy storage container is level, and finally the self-unloading or placement is completed. The lifting mechanism adopts a lifting cylinder, and the drive mechanism includes a hinged mounting plate and an extension cylinder. The level detection mechanism is an inclination sensor.

[0004] However, although the lifting cylinder used in the lifting mechanism can achieve precise control of the up and down displacement of the outriggers, the lifting cylinder needs to carry the oil tank and valve group at all times. In addition, the lifting mechanism, drive mechanism and level detection mechanism need to work together, resulting in a large number of components and complex control logic. It occupies space and increases the complexity of the system, which is not conducive to lightweight design. Utility Model Content

[0005] To address the aforementioned issues, this application provides a self-loading and unloading energy storage container.

[0006] The self-loading and unloading energy storage container provided in this application adopts the following technical solution: A self-loading and unloading energy storage container includes a housing, a battery pack, and a loading and unloading mechanism. The battery pack is built inside the housing, and the loading and unloading mechanism is installed on the housing. The loading and unloading mechanism includes a drive component and a support leg. The drive component is fixedly connected to the support leg, and the drive component drives the support leg to move up and down in a vertical direction. The drive component is electrically connected to the battery pack.

[0007] By adopting the above technical solution, the outriggers are driven to move vertically by direct electrical connection between the drive component and the battery pack. Compared with the lifting cylinder, which requires additional oil tanks, valve groups, and complex pipelines, the drive component only needs to form a power supply closed loop through electrical connection with the battery pack. This reduces the number of parts in the loading and unloading mechanism and reduces the space occupation problem caused by numerous components. At the same time, the direct electrical connection between the drive component and the battery pack simplifies the power transmission path, makes the control logic simpler, and reduces the overall system complexity. In the specific working process, the drive component drives the outriggers to descend vertically. When the end of the outrigger contacts the ground, the drive component continuously applies downward force, using the lever principle to lift the entire casing. This simplified design is more in line with the requirements of lightweight design and improves the convenience of self-loading and unloading operations and the stability of equipment operation.

[0008] Preferably, the outrigger includes a sleeve and a telescopic rod, and the driving member drives the telescopic rod to slide within the sleeve.

[0009] By adopting the above technical solution, the driving component drives the telescopic rod to slide inside the sleeve. With the help of the sleeve's guiding effect on the telescopic rod, the movement trajectory of the telescopic rod can be effectively limited, ensuring that the telescopic rod can extend and retract smoothly without deviation. In addition, this structure allows the telescopic rod to retract into the sleeve when the outrigger is stored, reducing space occupation and further ensuring the stability and convenience of the self-loading and unloading process.

[0010] Preferably, it further includes a storage mechanism, which is disposed between the loading / unloading mechanism and the housing. The storage mechanism includes a hinge seat and a connecting rod. The hinge seat is fixedly connected to the housing, and the connecting rod is rotatably supported by the hinge seat and rotates in the horizontal direction.

[0011] By adopting the above technical solution, the horizontal rotation of the connecting rod can flexibly adjust the unfolding and retraction state of the loading and unloading mechanism. When not in use, the outriggers can be rotated and retracted to the periphery of the housing, reducing space occupation and improving the reliability and convenience of the loading and unloading mechanism in unfolding and retraction.

[0012] Preferably, the storage mechanism further includes a pin, which is rotatably supported by the hinge seat, and the connecting rod is fixedly connected to the pin.

[0013] By adopting the above technical solution, the pin provides a stable horizontal rotation fulcrum for the connecting rod. Moving the connecting rod can flexibly drive the loading and unloading mechanism to rotate in the horizontal direction, realizing the deployment and storage of the outriggers, and greatly reducing the space occupied when idle.

[0014] Preferably, the hinge seat is provided with a first pin hole, and the connecting rod is provided with a second pin hole, the first pin hole and the second pin hole are connected.

[0015] By adopting the above technical solution, when the outriggers are in the deployed state, the operator can insert the pins into the aligned first and second pin holes to effectively lock the relative positions of the first and second pin holes, reducing structural instability caused by accidental rotation of the connecting rod during the raising and lowering of the outriggers, and ensuring the accuracy of the drive components in driving the outriggers to move vertically. When the outriggers need to be retracted, the connecting rod is rotated in the opposite direction to retract the loading and unloading mechanism to the outer wall of the housing. Similarly, the pins can be inserted into the aligned first and second pin holes to achieve mechanical fixation of the outriggers in the transport state of the energy storage container. This not only ensures the structural reliability in the working state but also improves the compactness and safety of the transportation process.

[0016] Preferably, the loading and unloading mechanism can be controlled wirelessly remotely.

[0017] By adopting the above technical solutions, the loading and unloading mechanism can be remotely controlled wirelessly, enabling operators to control the loading and unloading process from a distance. Remote control reduces the need for manual adjustments at close range, simplifies the operation process, and better adapts to the usage requirements of energy storage cabins under various working conditions.

[0018] Preferably, it further includes a support mechanism, which is installed at the bottom of the housing. The support mechanism includes casters and a support base. The casters are located at the bottom of the housing and are rotatable. The support base is located inside the casters and is fixedly connected to the bottom of the housing.

[0019] By adopting the above technical solution, during short-distance movement, the energy storage container is in a movable state by rotating the casters in contact with the ground, reducing the need for external equipment such as forklifts to propel the container autonomously. When transporting or parking over long distances, the casters can be flipped and stored, and the inner support base can stably support the overall structure, ensuring the stability of the container during transportation or when stationary. This structure integrates mobility and support functions, reduces the space occupied by additional components, and enhances the adaptability and reliability of the energy storage container in various working conditions such as emergency rescue and repair.

[0020] Preferably, the support base is a rubber base.

[0021] By adopting the above technical solution, the support base is set as a rubber base. By utilizing the elasticity and friction characteristics of rubber material, it can effectively buffer vibration and impact during transportation when the equipment is transported over long distances or when it is stationary, thereby reducing damage to internal components such as battery packs.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The drive unit is electrically connected to the battery pack to drive the outriggers to move vertically. Compared with the lifting cylinder, which requires an additional oil tank, valve group and complex pipelines, the drive unit only forms a power supply closed loop through electrical connection with the battery pack. This reduces the number of parts and space occupied by the loading and unloading mechanism, while simplifying the power transmission path and control logic, reducing system complexity. During operation, the drive unit drives the outriggers to descend and continuously apply force after touching the ground, using the lever principle to lift the casing. This simplified design meets the requirements of lightweighting and improves the convenience of self-loading and unloading operation and the stability of equipment operation. 2. The connecting rod rotates horizontally and is supported by the hinge seat, which can flexibly adjust the unfolding and retracting state of the loading and unloading mechanism. When not in use, the outriggers can be rotated and retracted to the outer wall of the housing, greatly reducing space occupation and further improving the reliability and adaptability of the self-loading and unloading process. 3. For short-distance movement, the energy storage container can be moved autonomously by flipping the casters, reducing reliance on external equipment such as forklifts. For long-distance transport or parking, the casters can be flipped and stored, and the support base can stably support the overall structure, ensuring stability during transportation and when stationary. This structure integrates movement and support functions, reduces the space occupied by additional components, and effectively enhances the adaptability and reliability of the energy storage container in various working conditions such as emergency rescue and repair.

[0031] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0032] This application discloses a self-loading and unloading energy storage container, referring to... Figure 1 and Figure 2 A self-loading and unloading energy storage container includes a housing 1, a loading and unloading mechanism 2, a storage mechanism 3, and a support mechanism 4. The housing 1 is rectangular in shape. In this embodiment, the housing 1 is made of high-quality metal material to ensure normal operation under various harsh environments and climatic conditions. It is corrosion-resistant, rust-proof, and has a wind resistance level of up to level 8.

[0033] Meanwhile, the casing 1 is equipped with a battery pack 5 with a battery capacity of 20kWh. The battery pack 5 is made of lithium iron phosphate cells, which are highly safe and have a long service life, and can be charged and discharged more than 2,000 times. In addition, the energy storage capacity inside the casing 1 can be 20 kWh, 30 kWh, or 40 kWh, depending on the customized requirements. Usually, the energy storage capacity is set to 20 kWh.

[0034] Furthermore, the loading and unloading mechanism 2, the storage mechanism 3, and the support mechanism 4 are all installed on the housing 1. The loading and unloading mechanism 2 can realize self-loading and unloading functions on the housing 1. The storage mechanism 3 can store the loading and unloading mechanism 2 so that the loading and unloading mechanism 2 is folded into the outer wall of the housing 1. The support mechanism 4 can also make the housing 1 move flexibly. The combination of the loading and unloading mechanism 2 and the support mechanism 4 enables the energy storage container to have the ability to load, unload, and move autonomously, thus enabling the energy storage container to complete loading, unloading, and moving operations on its own. Specifically, the loading and unloading mechanism 2 includes a drive component 21 and a support leg 22. The drive component 21 is fixedly connected to the support leg 22 and electrically connected to the battery pack 5. The drive component 21 is configured as an electric push rod. Since the drive component 21 is electrically connected to the battery pack 5, it can convert the electrical energy provided by the battery pack 5 into mechanical energy to provide power for the movement of the support leg 22, so that the support leg 22 can be displaced in the vertical direction. In addition, in this embodiment, the loading and unloading mechanism 2 is provided in four sets, which are located at the four right-angled sides of the housing 1. Furthermore, since the drive unit 21 is directly electrically connected to the battery pack 5 to drive the outrigger 22 to move in the vertical direction, compared to the lifting cylinder which requires an additional oil tank, valve group and complex pipelines, the drive unit 21 only forms a power supply closed loop through electrical connection with the battery pack 5. This reduces the number of parts in the loading and unloading mechanism 2 and the space occupation problem caused by the large number of components. At the same time, the direct electrical connection between the drive unit 21 and the battery pack 5 simplifies the power transmission path, makes the control logic simpler, and reduces the overall complexity of the system. This streamlined design is more in line with the requirements of lightweight design and improves the convenience of self-loading and unloading operation and the stability of equipment operation. Reference Figure 3 Meanwhile, the outrigger 22 includes a sleeve 221 and a telescopic rod 222. The telescopic rod 222 is slidably disposed inside the sleeve 221. In this embodiment, the electric push rod is provided with a movable end that can slide, which is disposed at the lower end of the electric push rod. The lower end of the electric push rod is fixedly connected to the sleeve 221, and the movable end of the electric push rod is fixedly connected to the telescopic rod 222. Furthermore, the storage mechanism 3 is also provided with four sets, which correspond one-to-one with the loading and unloading mechanism 2. The storage mechanism 3 also includes a hinge seat 31, a connecting rod 32 and a pin 33. The hinge seat 31 is fixedly connected to the housing 1. The pin 33 is vertically set and rotates on the hinge seat 31. The connecting rod 32 is fixedly connected to the pin 33 and rotates around the pin 33 on the hinge seat 31. The operator can move the connecting rod 32 to make the connecting rod 32 rotate in the horizontal direction. In addition, the loading and unloading mechanism 2 can be remotely controlled wirelessly. Operators can use a remote control with signal transmission function to control the operation of the loading and unloading mechanism 2 via wireless signals. This explains that when the energy storage container is not in operation, the loading and unloading mechanism 2 is completely retracted to the outer wall of the housing 1 through the storage mechanism 3. When the energy storage container starts working, the operator moves the connecting rod 32 to rotate around the pin 33 and unfold it. At this time, the movable end of the electric push rod drives the telescopic rod 222 to descend vertically along the sleeve 221. At the moment when the end of the telescopic rod 222 touches the ground, the electric push rod continuously applies downward force, lifting the housing 1 as a whole through the lever principle. Reference Figure 4 and Figure 5 Meanwhile, the hinge seat 31 is provided with a first pin hole 311, as shown in the reference. Figure 6 and Figure 7 The connecting rod 32 is provided with a second pin hole 321. When the connecting rod 32 rotates at a certain angle, the first pin hole 311 and the second pin hole 321 are connected. When the first pin hole 311 and the second pin hole 321 are aligned, the pin 7 can be inserted to fix the connecting rod 32 in a specific position, ensuring the stability of the loading and unloading mechanism 2 during operation. Furthermore, the support mechanism 4 includes casters 41 and support bases 42. The casters 41 are located at the bottom of the housing 1. In this embodiment, four casters 41 are provided, located at the four corners of the bottom of the housing 1. The casters 41 are rotatable. Four support bases 42 are provided, located inside the casters 41, and the support bases 42 are fixedly connected to the bottom of the housing 1. Furthermore, during short-distance movement, the casters 41 are foldable, allowing the energy storage container to move by rolling on the casters 41. This reduces the need for external equipment such as forklifts, enabling the container to move autonomously. For long-distance transport or parking, the casters 41 can be folded up and stored, with the inner support base 42 providing stable support for the overall structure, ensuring the stability of the container during transport or when stationary. This structure integrates movement and support functions, reduces the space occupied by additional components, and enhances the adaptability and reliability of the energy storage container in various working conditions such as emergency rescue and repair. In addition, the support base 42 is set as a rubber base. Utilizing the elasticity and friction properties of rubber, it can effectively buffer vibration and impact during transportation when the equipment is transported over long distances or when it is stationary, thereby reducing damage to internal components such as the battery pack 5. Meanwhile, the protective lights on both sides of the modular shelter are two 50W LED lights, which can provide lighting and safety reminders for close-range construction and operation.

[0035] In addition, this energy storage container supports dual-mode charging from mains power and high-voltage charging piles, and has a wide voltage output capability of 220V / 380V, which can adapt to the power needs of equipment of different sizes. It can realize the power superposition of two or more devices to meet the application of larger load scenarios. The maximum output power of the energy storage container reaches 60kVA, and can provide 20 minutes of continuous power supply under full load, fully covering short-term high-load power demand scenarios such as emergency repairs and temporary construction. The specially designed mains power parallel protection function can automatically switch to energy storage power supply mode when the mains power is abnormal, and achieve seamless power replenishment through pre-parallel connection to ensure the continuous operation of critical loads.

[0036] The implementation principle of a self-loading and unloading energy storage container in this application embodiment is as follows: When not in operation, the loading and unloading mechanism 2 is folded into the outer wall of the housing 1 by the storage mechanism 3, the remaining power of the battery pack 5 is checked, and if charging is required, it is connected to the mains power or a high-voltage charging pile for replenishment. The energy storage container is then moved to the designated working position by the casters 41.

[0037] The operator rotates the connecting rod 32 around the vertical pin shaft 33 to the working angle, ensuring that the second pin hole 321 of the connecting rod 32 is aligned with the first pin hole 311 of the hinge seat 31, and then inserts the pin 7. The operator controls the remote control to start the electric push rod, driving the telescopic rod 222 to descend vertically along the sleeve 221. After the end of the telescopic rod 222 touches the ground, it continues to apply downward force, using the lever principle to lift the entire housing 1 to the height above the ground, flipping the caster 41 to abut against the housing 1, and storing the caster 41.

[0038] Select the 220V / 380V output interface according to your needs to connect loads such as emergency lighting and repair tools. If a higher power is required, connect two or more devices through the parallel interface to aggregate the output to 60kVA. The 50W LED protective lights on both sides of the energy storage cabin will automatically start to provide close-range construction lighting and safety warnings.

[0039] When the energy storage container is in power supply mode, the equipment is pre-connected to the mains power. When the mains power is abnormal, the system automatically switches to the energy storage power supply mode, and the energy storage container is seamlessly replenished with power to ensure the continuous operation of critical loads. Under full load, it can provide power for 20 minutes.

[0040] When the energy storage container finishes its work, the electric push rod reverses and drives the telescopic rod 222 to rise. After leaving the ground, it continues to rise to the top of the sleeve 221, releases the pin 7 of the connecting rod 32, and rotates the connecting rod 32 around the pin shaft 33 to bring the loading and unloading mechanism 2 into contact with the housing 1, and inserts the pin 7 to fix it.

[0041] When the energy storage container needs charging, it is connected to the mains power or a high-voltage charging pile to replenish energy through lithium iron phosphate cells, thus storing electricity for the next use.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
