Description

Technical Field

[0001] This utility model relates to the field of safety management of energy storage power stations, and in particular to a box, system and power station for storing and safely separating energy storage battery modules. Background Technology

[0002] As an important power reserve facility, energy storage power stations can efficiently store and release electrical energy, and are widely used in renewable energy systems with intermittent and fluctuating characteristics, such as photovoltaic power generation and wind power generation. By storing excess electrical energy in energy storage units and releasing it during peak grid loads or power outages, energy storage power stations can not only play a role in peak shaving and valley filling, frequency regulation and voltage stabilization, but also serve as a backup power source during sudden power outages, improving the continuity and reliability of power supply.

[0003] Currently, lithium-ion batteries, as a representative of energy storage devices, have become the mainstream configuration solution for energy storage power stations due to their high energy density and long cycle life. However, lithium-ion batteries still have inherent defects in thermal management and safety control. When a single battery cell or module experiences overheating, internal short circuits, or other abnormal conditions, it is highly susceptible to thermal runaway, which can lead to combustion or even explosion accidents. Since energy storage power stations typically integrate a large number of battery modules, if a single module experiences thermal runaway, it is highly likely to trigger a chain reaction in adjacent modules, resulting in large-scale explosions and causing severe property damage and casualties.

[0004] To address the aforementioned issues, existing energy storage power stations mostly rely on temperature sensors, sprinklers, or gas extinguishing systems installed inside the enclosure to suppress the spread of fire. However, these solutions often struggle to isolate failed modules in a timely and effective manner. Especially when the enclosure space is limited and heat dissipation is poor, heat conduction is rapid, and traditional fire extinguishing methods cannot quickly sever the physical contact between the thermal runaway module and surrounding modules, thus failing to prevent the accident from spreading.

[0005] Therefore, there is an urgent need for an energy storage system structure that can quickly isolate a battery module from the battery pack inside the energy storage box when an abnormality occurs, so as to significantly improve the overall safety and accident controllability of the energy storage power station.

[0044] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0045] This invention provides a housing, system, and energy storage power station for storing and safely separating energy storage battery modules, enabling independent and rapid detachment of the battery modules in the event of thermal runaway or other abnormalities.

[0046] Figure 1 This is a schematic diagram of a safe separation box for energy storage batteries provided in an embodiment of the present utility model; the box includes: a box body 1, an insulated door body 2 with an opening and closing structure, multiple slide rails 3, and multiple battery clips 4.

[0047] Figure 2 This is a schematic diagram of the housing body provided in an embodiment of the present utility model. The insulated door 2, with an opening and closing structure, is disposed on the opening side of the housing body 1. The door 2 has an isolation function, capable of isolating the battery module from the outside environment and also providing heat insulation. Specifically, it can include a roller shutter door, a hinged door, or a door with a hinged window, etc. The hinged window can be configured corresponding to the battery module loading position. In this embodiment... Figure 2 Taking an insulated roller shutter door as an example, the opening and closing of the insulated roller shutter door 2 is achieved through a roller shutter door storage box 21 installed on the main body 1. When the insulated roller shutter door 2 is fully lowered, it forms a battery module storage box structure together with the main body 1. It is understood that the box also includes a heat dissipation structure, which can dissipate heat outwards from the box by being installed at the top, bottom, side walls, or upper part of the insulated door body.

[0048] Multiple slide rails 3 are fixed in pairs at an angle to two opposite side walls of the housing body, and are set at an angle downward from the inside of the housing towards the opening to form multiple battery module loading positions; preferably, the angle of downward tilt is 20°-60°.

[0049] Figure 3 This is a schematic diagram of the slide rail structure provided in an embodiment of the present utility model. Figure 3 In the specific example shown, the slide rail 3 includes a fixed surface 31 and a bearing surface 32; wherein, the fixed surface 31 is fixed to the side wall of the housing body 1, and the bearing surface 32 bears the energy storage battery module. The slide rail can be made of materials such as stainless steel or aluminum alloy.

[0050] Optionally, the slide rail 3 also includes a lateral support surface 33; the lateral support surface 33 is parallel to the fixed surface 31 and is vertically disposed on the bearing surface 32; the inner surface of the lateral support surface 33 is disposed opposite to the side of the energy storage battery module, limiting the lateral movement of the energy storage battery module on the slide rail 3.

[0051] Figure 4 This is a schematic diagram of a battery clip structure provided in an embodiment of the present utility model. Figure 4 In the specific example shown, the battery clip 4 includes a fastening part 41, a fixing connection part 42, and a connecting shaft (not shown in the figure); wherein, the fixing connection part 42 has a convex structure; the fastening part 41 includes a connecting part 411 and a battery contact part 412, the battery contact part 412 being perpendicularly connected to the connecting part 411; the connecting part 411 has a concave structure, which is adapted to the convex fixed connection part 42, and the two are internally hinged together by the connecting shaft; when the connecting part 411 is in the first position where it is horizontally connected to the fixing connection part 42 (e.g. Figure 4 (as shown in a), the battery latch 4 is in the closed state, and the battery contact part 412 abuts against and locks the energy storage battery module; when the connecting part 411 is in the second position where it is perpendicularly connected to the fixed connecting part 42 (as shown in a), the battery latch 4 is in the closed state, and the battery contact part 412 abuts against and locks the energy storage battery module; when the connecting part 411 is in the second position where it is perpendicularly connected to the fixed Figure 4 As shown in b), the battery clip 4 is in the open state.

[0052] Furthermore, it is understood that the battery clip 4 proposed in this example is only a device for fixing or releasing the battery, and other similar devices such as retractable limiting blocks and pull straps are also included in this patent.

[0053] Figure 5 This is a schematic diagram showing the battery module locked in the battery module loading position composed of the battery clip and the slide rail 3, according to an embodiment of this utility model. (Combined with...) Figures 3-5 As shown, each battery clip 4 is fixed to the end of a slide rail 3 on the open side. For example, the battery clip 4 can be fixed to the slide rail 3 by fixing the fixing connection part 42 to the lateral support surface 33. Of course, this is just one example of a connection method. Other equivalent fixing structures can also be used to install the battery clip 4 at the end of the slide rail 3. For example, it can be set by threaded connection, slot insertion, welding, riveting, or a detachable locking structure. In specific implementation, the fixing method of the battery clip 4 can be flexibly selected according to factors such as the cabinet material and space layout.

[0054] Combination such as Figure 1 and Figure 5 As shown in the structure, each energy storage battery module 10 is supported on a pair of slide rails 3; when the battery latch 4 is closed, the battery latch 4 is fastened to one end of the energy storage battery module 10, and the energy storage battery module 10 is stored in the battery module loading position inside the box; when both the battery latch 4 and the heat-insulating roller shutter door 2 are open, the energy storage battery module 10 can slide out of the battery module loading position from the opening side to the outside of the box under the action of gravity along the slide rail 3.

[0055] To enable the rapid sliding out of the energy storage battery module, the housing may optionally include a push-out assist device (not shown in the figure) to assist the sliding out of the battery module, especially to assist in initiating the sliding out action.

[0056] The ejection assist device may include an assist device fixing part and an ejection assist component.

[0057] The assist device fixing part is located on the rear wall of the housing body 1 opposite to the opening side, or on the end of the slide rail 3 on the rear wall side. The assist device fixing part can be a fixed crossbeam, bracket or similar structure, or it can be a guide rail, robotic arm or similar structure that can be adjusted in the up and down and / or left and right directions along the rear wall of the housing under the control of a control signal.

[0058] The ejection assist component can be specifically a mechanical ejection component or an elastic release component; the mechanical ejection component can include, but is not limited to: electric push rod, screw drive mechanism, pneumatic push rod, hydraulic cylinder, cam ejection mechanism or gear-rack drive mechanism, etc.; the elastic release component can include, but is not limited to: spring release structure, shape memory alloy drive component, airbag ejection component, magnetic repulsion release component or elastic sheet energy storage release structure, etc.; they can be used to provide initial sliding assistance to the battery module after the fixed length buckle is released, so that the energy storage battery module starts sliding from a stationary state.

[0059] The push-out assist component includes a fixed end and an assist-pushing end, with the fixed end mounted on the fixed part of the assist device. The assist-pushing end abuts against the end of the energy storage battery module when it is in the battery module loading position, or it abuts against the end of the energy storage battery module during the initial assist phase of the module's sliding out. For example, when the energy storage battery module is in the loading position, it can be elastically compressed against the end of the battery module using a spring or elastic sheet, providing initial pushing force immediately after the battery clip is released. Alternatively, when the energy storage battery module is in the loading position, the tip of the electric push rod may not contact the energy storage battery module; the extension of the electric push rod tip is only activated when push-out is required, pushing the end of the battery module to provide pushing force.

[0060] The enclosure proposed in this embodiment also includes electrical connection components for connecting to the positive and negative terminals of the energy storage battery module. Specific implementation methods may include, but are not limited to, the following:

[0061] Electrical connection terminals are provided on the battery clips. When the battery clips are engaged with the energy storage battery module, the positive and negative terminals of the energy storage battery module are connected to the electrical connection terminals on the battery clips, respectively; when the battery clips are disengaged, the energy storage battery module is disconnected from the electrical connection terminals.

[0062] The energy storage battery module has plugs at its positive and negative terminals, which connect to the female connector located inside the housing. When the energy storage battery module is pushed into the battery module loading position, the plug and the female connector are connected electrically. When the energy storage battery module slides out of the battery module loading position, the plug and the female connector automatically disconnect the electrical connection.

[0063] Flexible cables extend from the positive and negative terminals of the energy storage battery module and connect to busbars installed inside the enclosure. In this scenario, a cable cutting device is also installed inside the enclosure; when the energy storage battery module slides out of the battery module loading position, the cable cutting device is triggered simultaneously to cut the flexible cables.

[0064] In summary, the energy storage battery module storage and safe separation enclosure provided in this embodiment, through the coordinated operation of slide rails, battery clips, an insulated door with an opening and closing structure, and an optional push-out assist device, enables stable storage and rapid, safe separation of the energy storage battery module within the enclosure. Simultaneously, the electrical connection components enable automatic electrical connection and disconnection of the energy storage battery module during loading and unloading, ensuring electrical safety and ease of operation.

[0065] Anomaly detection and control circuits are installed in the aforementioned enclosure to form a system for storing and safely separating energy storage battery modules. This system can accurately identify anomalies or thermal runaway when an energy storage battery module malfunctions. By triggering the automatic opening of the battery latch and the insulated door with an opening and closing structure, combined with a gravity sliding structure and an optional assisted push-out mechanism, the malfunctioning battery module can be quickly slid out of the enclosure, thereby effectively avoiding heat diffusion and chain reactions, and improving the overall safety and maintainability of the energy storage system.

[0066] The system for storing and safely separating energy storage battery modules includes the aforementioned enclosure, anomaly detection circuit, and control circuit.

[0067] An anomaly detection circuit can be installed within the enclosure and / or the energy storage battery module. In a specific example, the anomaly detection circuit includes: a sensor, a signal processing module, and a communication module. The sensor collects status signals from the energy storage battery module and / or the enclosure and sends them to the signal processing module, which outputs a detection signal based on the status signals. The communication module transmits the detection signal to the control circuit and / or an external monitoring and alarm system via wired or wireless means; for example, depending on the system configuration, data transmission can be performed using CAN bus communication or wireless LAN communication. The sensor includes one or more of the following: a temperature detection device, a gas detection device, a smoke detection device, a thermal imaging device, a pressure detection device, or an electrical parameter detection device. More specifically, it can include: a temperature detection device, a gas detection device, a smoke alarm device, a thermal imager, or a camera installed within the enclosure, used to monitor changes in environmental parameters inside the enclosure in real time; it can also include: a temperature sensor, a pressure sensor, a voltage detection circuit, a current detection circuit, or a short-circuit detection circuit installed within the energy storage battery module, used to detect the operating status of the battery module in real time. The anomaly detection circuit can be configured to send detection signals in real time or at regular intervals.

[0068] The control circuit is connected to the insulated door with an opening and closing structure and the battery clip via wired or wireless means. After the anomaly detection circuit sends a detection signal to the control circuit, the control circuit generates a first control signal based on the detection signal to control the opening and closing of the insulated door with an opening and closing structure, and generates a second control signal to control the opening and closing of the battery clip.

[0069] In a specific example, the control circuit includes a microcontroller, an interface module, a motor drive module, and an actuator drive module. The microcontroller receives detection signals from the anomaly detection circuit. When an anomaly is detected, it sends a first control signal to the motor drive module via the interface module to open the insulated door with an opening and closing structure. It also sends a second control command to the actuator drive module via the interface module to open the battery latch in the battery module loading position indicated by the anomaly detection signal. Optionally, other control commands can be generated to drive the push-out assist device to push out the energy storage battery module in the battery module loading position indicated by the anomaly detection signal, allowing it to slide out of the housing along a slide rail.

[0070] Optionally, an in-situ monitoring device is also installed inside the enclosure. This could be an infrared photocell, photodetector, or laser displacement sensor positioned opposite each other on either side of the enclosure, or a pressure sensor mounted on the slide rail. This device monitors the position of the energy storage battery module in its loading position in real time. The in-situ monitoring device can determine whether the energy storage battery module is in its loading position or has completely slid out of the enclosure by detecting changes in the energy storage battery module's signal obstruction to the light signal or changes in pressure sensed by the pressure sensor. After the control circuit determines, based on the signal output from the in-situ monitoring device, that the abnormal energy storage battery module has completely detached from the end of the slide rail and slid out of the enclosure, the microcontroller can generate a first control signal to automatically close the insulated door with an opening and closing structure. This physically isolates the abnormal energy storage battery module from the internal space of the enclosure, preventing heat, smoke, or flames from spreading into the enclosure and ensuring operational safety within the enclosure.

[0071] In a preferred embodiment, the system also includes a battery safety treatment device. The control circuit can also be linked to the battery safety treatment device for localized spraying or inert gas release, forming multiple layers of safety protection and further improving the operational safety of the energy storage system.

[0072] In a specific example, a system with a battery safety handling device, such as Figure 6 As shown.

[0073] The battery safety devices are located outside the enclosure on the open side, including the energy storage battery module safety handling tank 5 and / or fire-fighting device 6;

[0074] The energy storage battery module 10 slides out of the enclosure and falls into the energy storage battery module safety handling tank 5. The fire-fighting device 6 then performs fire-fighting treatment on the energy storage battery module 10 that has fallen into the safety handling tank. Depending on the type of battery cell in the battery module, different fire-fighting agents can be used in the fire-fighting device 6. For example, perfluoroethyl ketone or dry powder fire extinguishing agents can be used for lithium-ion batteries.

[0075] Preferably, the safety handling tank 5 is equipped with a pressure sensor or a contact detection switch to detect the battery module falling in and generate a corresponding battery falling signal. This signal is transmitted to the microcontroller and then sent to the drive control unit of the fire-fighting device 6, or directly to the drive control unit of the fire-fighting device 6, to control the activation of the fire-fighting device 6.

[0076] Figure 7 This diagram illustrates the working state of the battery safety handling device in the system for storing and safely separating energy storage battery modules, as provided in this embodiment of the invention. The complete working process of the enclosure and system for storing and safely separating energy storage battery modules, as proposed in this embodiment, will be explained with reference to this diagram.

[0077] Example 1

[0078] In a specific working scenario, the system is in normal operation. Temperature sensors installed inside each energy storage battery module and gas detection devices installed inside the enclosure monitor the temperature parameters inside the module and the hydrogen concentration parameters inside the enclosure in real time, respectively. The analog temperature signal output by the temperature sensor and the gas concentration signal output by the gas detection device are converted into corresponding electrical signals after voltage conversion and filtering, and then input to the signal processing module. The signal processing module performs analog-to-digital conversion (A / D conversion) on the received analog signal, converting it into a digital signal, and then sends it to the interface module of the control circuit through the communication module.

[0079] After receiving the digital signal from the communication module, the interface module transmits it to the microcontroller (MCU). The microcontroller pre-stores the correspondence between the numbers and locations of each energy storage battery module, as well as thermal runaway determination thresholds for temperature and gas concentration. In this example, if the microcontroller continuously receives temperature sensor data from the fourth energy storage battery module within a preset time (3 seconds), indicating that the module's temperature is consistently above 90°C, and simultaneously receives data from the gas detection device indicating that the hydrogen concentration has increased to more than 2% of the air volume fraction, the microcontroller determines, based on the preset threshold conditions, that the module is in a critical state where thermal runaway is imminent.

[0080] Based on the determination result, the microcontroller generates a first control signal and a second control signal: the first control signal is transmitted to the motor drive module via the interface module, and the motor drive module outputs a drive signal according to the first control signal to control the start of the insulated roller shutter door motor, so that the insulated roller shutter door quickly rolls up into the roller shutter door storage box, thereby opening the opening at the front end of the box body and forming a channel for the module to slide out; the second control signal is transmitted to the actuator drive module via the interface module, and the actuator drive module outputs a drive current to the electromagnetic actuator of the battery clip corresponding to the loading position of the fourth energy storage battery module, so that the connecting part of the battery clip rotates around the connecting shaft to a vertical position, releasing the mechanical lock on the fourth energy storage battery module, and at the same time, disconnecting the electrical connection between the battery clip and the positive and negative terminals of the battery module.

[0081] After the battery latch is opened, the fourth energy storage battery module slides along the inclined slide rail towards the opening at the front of the enclosure under its own gravity. Photodetectors located on both sides of the slide rail monitor the light signal obstruction status within the slide rail channel in real time. The output signals of the photodetectors are transmitted to the microcontroller via a wired connection. When the microcontroller detects that the infrared phototransistor output signal has returned to a clear state from an obstructed state and remains stable for more than a predetermined time threshold (e.g., 100ms), it determines that the fourth energy storage battery module has completely slid off the end of the slide rail and successfully detached from the enclosure body. At the same time, the microcontroller generates a new first control signal, which is transmitted to the motor drive module via the interface module. The motor drive module outputs a drive signal based on the new first control signal, controlling the insulated roller shutter door motor to restart, causing the insulated roller shutter door to descend to the closed position, re-closing the front opening of the enclosure and restoring the insulated state of the front side of the enclosure.

[0082] The fourth energy storage battery module slides out and falls directly into the safety handling tank located below the opening of the enclosure under the influence of gravity. A pressure sensor inside the safety handling tank detects the module's entry and generates a control signal to activate the fire suppression system's drive control unit, which then initiates a localized spray system on the fourth energy storage battery module.

[0083] After the insulated roller shutter door is fully closed and the limit detector confirms the closed state, the microcontroller uploads the abnormal data, sliding status, and fire-fighting device activation status of the fourth energy storage battery module to an external host computer monitoring system or remote alarm terminal to realize system status updates and safety event recording.

[0084] In this embodiment, the fourth energy storage battery module is quickly identified and automatically separated before thermal runaway, and safely detached by sliding out by gravity. At the same time, local spraying is used for fire extinguishing and suppression. The heat and smoke generated are effectively controlled in the safety treatment tank and will not affect other energy storage battery modules inside the box, thereby ensuring the operational safety of the entire energy storage system.

[0085] Example 2

[0086] In a specific working scenario, when the system is operating normally, temperature sensors installed inside each energy storage battery module and smoke detectors installed inside the enclosure monitor the temperature parameters inside the module and the smoke concentration parameters inside the enclosure in real time, respectively. The analog temperature signal output by the temperature sensor and the smoke concentration signal output by the smoke detector are converted into corresponding electrical signals after voltage conversion and filtering, and then input to the signal processing module. The signal processing module performs analog-to-digital conversion (A / D conversion) on the received analog signal, converting it into a digital signal, and then sends it to the interface module of the control circuit through the communication module.

[0087] After receiving the digital signal from the communication module, the interface module transmits it to the microcontroller (MCU). The microcontroller pre-stores the correspondence between the numbers and locations of each energy storage battery module, as well as thermal runaway determination thresholds for temperature and smoke concentration. In this example, within a preset time (3 seconds), the microcontroller continuously receives temperature sensor data from the fourth energy storage battery module, indicating that the module's temperature remains above 90°C. Simultaneously, it receives data from the smoke detection device indicating that the smoke concentration inside the chamber has increased to 0.08% of the air volume fraction, exceeding the preset safety threshold. Based on the preset threshold conditions, the microcontroller determines that the module is in a critical state where thermal runaway is imminent.

[0088] Based on the determination result, the microcontroller generates a first control signal, a second control signal, and a third control signal:

[0089] The first control signal is transmitted to the motor drive module via the interface module. The motor drive module outputs a drive signal according to the first control signal to control the motor of the opening and closing door to start, so that the opening and closing door opens quickly, thereby opening the front opening of the box and forming a channel for the module to slide out.

[0090] The second control signal is transmitted to the actuator drive module via the interface module. The actuator drive module outputs a drive current to the electromagnetic actuator of the battery clip corresponding to the loading position of the fourth energy storage battery module, causing the connecting part of the battery clip to rotate around the connecting shaft to a vertical position, thus releasing the mechanical lock on the fourth energy storage battery module. Simultaneously, during the sliding process, the cable cutting device is triggered to cut off the flexible cable from the port of the energy storage battery module, achieving a safe disconnection of the electrical connection and thus avoiding short circuits or electrical risks during the module sliding out.

[0091] The third control signal is transmitted via the interface module to another output channel of the actuator drive module, controlling the operation of the push-out assist device located on the rear wall of the housing. This push-out assist device includes a robotic arm capable of adjusting its position along the rear wall of the housing in the up, down, left, and right directions, and an electric push rod on the robotic arm. Under the command of the microcontroller, the robotic arm moves the electric push rod to the end position of the fourth energy storage battery module. The electric push rod applies an initial pushing force to the end of the battery module, providing a starting assist for the battery module to slide out along the slide rail.

[0092] After the battery latch opens and the ejection assist device is in place, the fourth energy storage battery module slides along the inclined slide rail towards the front opening of the housing under the combined action of initial pushing force and gravity. A pressure sensor on the slide rail continuously monitors the pressure exerted on the module. When the pressure sensor detects that the pressure on the corresponding energy storage battery module has dropped to 0, the microcontroller determines that the module has completely detached from the end of the slide rail and successfully slid out of the housing.

[0093] When the fourth energy storage battery module slides out and falls into the safety handling slot located below the opening of the enclosure, the contact detection switch inside the safety handling slot is triggered, generating a control signal. The microcontroller then generates a fourth control signal, which is sent to the drive control unit of the fire suppression system via the interface module. The fire suppression system activates the inert gas release system to rapidly extinguish and cool the fourth energy storage battery module that has fallen into the safety handling slot, thereby suppressing further spread of thermal runaway.

[0094] After the module slides out and triggers the release of inert gas, the microcontroller generates a new first control signal, which is transmitted to the motor drive module via the interface module to control the door to close to the closed position, restoring the heat insulation state of the front side of the enclosure.

[0095] After the door is fully closed, the microcontroller uploads the abnormal data, sliding status, and inert gas release status of the fourth energy storage battery module to the host computer monitoring system or remote alarm terminal through the communication module, so as to realize system status update and safety event recording.

[0096] In this embodiment, the fourth energy storage battery module is quickly identified and automatically separated before thermal runaway. It is safely detached with the help of gravity sliding and push-out assist devices. At the same time, fire is extinguished and suppressed by the release of inert gas. The heat and smoke generated are effectively controlled in the safety treatment tank and will not affect other energy storage battery modules inside the box, thereby ensuring the operational safety of the entire energy storage system.

[0097] The system provided by this utility model for storing and safely separating energy storage battery modules can accurately identify abnormalities and automatically slide out when the battery module malfunctions or experiences thermal runaway. After the battery module is slid out, it is isolated and safely disposed of, thus constructing an energy storage battery safety protection system that integrates safety monitoring, automatic separation, and emergency handling.

[0098] This utility model provides a system for the storage and safe separation of energy storage battery modules, which can be widely used in large-scale energy storage power stations, distributed energy storage systems, and mobile energy storage devices. During the operation of an energy storage power station, each energy storage battery module may experience abnormal temperature or thermal runaway risks under prolonged charging and discharging or high power fluctuation conditions. This system, through the coordinated design of the enclosure, opening and closing door, battery latch, slide rail, and optional ejection assist device, combined with anomaly detection units such as smoke detectors, temperature sensors, and pressure sensors, can monitor the status of energy storage battery modules in real time. Once an abnormal module is identified, the microcontroller generates a control signal to drive the opening and closing door and battery latch to automatically operate, allowing the abnormal battery module to slide quickly and safely out of the enclosure along the slide rail. It is then isolated and extinguished with inert gas using a safety handling device, effectively preventing heat diffusion and chain reactions, and ensuring the safety and reliability of other battery modules and the overall system operation in the energy storage power station.

[0099] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
