Description

Technical Field

[0001] This application belongs to the field of energy storage equipment technology, and particularly relates to an energy storage device, energy storage system, charging network and handle. Background Technology

[0002] Thermal management systems in energy storage containers typically employ numerous valves to regulate the circulation of cooling media, with butterfly valves being a common example. Each valve is equipped with a rotating handle that is integrally integrated with the valve core, making it an inseparable component of the valve. However, this fixed integration of the handle with the valve core leads to several issues: multiple fixed handles occupy additional space within the energy storage container, impacting equipment layout and the ease of adjustment and maintenance. Utility Model Content

[0003] The purpose of this application is to provide an energy storage device, an energy storage system, a charging network, and a handle, which aims to save internal installation space of the energy storage device and improve the convenience of the regulating and maintenance valve structure.

[0004] To achieve the above objectives, according to a first aspect of the embodiments of this application, an energy storage device is provided, including a battery device and a heat exchange mechanism. The heat exchange mechanism includes a supply section, a plurality of heat exchange sections, and a plurality of valve structures. The heat exchange sections are configured to be thermally connected to the battery device. The supply section and the heat exchange sections are connected through the valve structures. The plurality of valve structures are correspondingly arranged with the plurality of heat exchange sections. Each valve structure includes a valve body and a valve core. The valve body connects the heat exchange sections and the supply section to form a channel for the flow of a heat exchange medium. A portion of the valve core is installed in the valve body. The valve core has a valve head that extends out of the valve body. The valve head has a first mating structure for detachable connection with a handle. The valve heads of the plurality of valve bodies are configured to be detachably connected to the same handle.

[0005] The core of the energy storage device provided in this application lies in configuring the valve head of the valve core of the valve structure to be detachably connected to the same handle. This allows one handle to be used to adjust the valve cores of multiple valve structures. In other words, the handle is detached from the valve structure during normal operation of the energy storage device, storing or outputting electrical energy. The handle is only used to adjust the valve core when adjustment or maintenance is required; it is ready to use immediately and disassembled after use. This effectively saves internal installation space in the energy storage device cabinet and improves the flexibility of the internal layout. Furthermore, operators can carry the handle with them and readily access it to adjust and maintain the valve structures that require adjustment or maintenance, thereby improving the convenience and efficiency of valve structure adjustment and maintenance.

[0006] In some embodiments, the valve structure further includes a sleeve connected to the valve body, with the valve head rotatably passing through the sleeve. The sleeve has multiple position holes circumferentially spaced around the axis of the sleeve. A positioning hole is provided on the circumferential sidewall of the valve head, configured to characterize the opening degree of the valve core relative to the valve body by aligning with the position holes. This reduces the uncertainty caused by adjustments based solely on touch or visual judgment, improves the accuracy of heat exchange medium flow control, and consequently enhances the temperature management accuracy and stability of the battery device.

[0007] In some embodiments, the valve structure further includes a first positioning member, which is inserted into one of the position holes and a corresponding positioning hole. This improves the stability of the valve core's opening position relative to the valve body and effectively reduces the possibility of accidental rotation or movement of the valve core due to vibration, impact, or accidental contact during the operation of the energy storage device.

[0008] In some embodiments, the valve head is housed within a sleeve, and a first mating structure is disposed on the circumferential sidewall of the valve head. The sleeve has a clearance notch, and the first mating structure is disposed corresponding to the clearance notch. The clearance notch is used to allow a handle to pass through for detachable connection with the first mating structure. The handle extends into the sleeve through the clearance notch and is detachably connected to the first mating structure on the circumferential sidewall of the valve head.

[0009] In some embodiments, the first mating structure is configured as a socket, which is coaxially arranged and connected to the positioning hole. This allows for a tighter and more secure connection between the handle and the valve head, effectively reducing the risk of shaking or detachment during operation, thereby improving operational reliability.

[0010] In some embodiments, the valve head is housed within a sleeve, with the end of the sleeve away from the valve body being configured as an open end. A first mating structure is provided on the end wall of the valve head away from the valve core. The open end is used for the handle to pass through and be detachably connected to the first mating structure. The connection method of inserting from the top of the sleeve makes the installation and removal of the handle more intuitive and convenient, improving the ease of operation.

[0011] In some embodiments, the surface of the valve head away from the valve core is flush with the end face of the sleeve, making the valve structure of the energy storage device appear cleaner and more integrated.

[0012] According to a second aspect of this application, an energy storage system is provided. The energy storage system includes: Energy conversion system; and As mentioned above, in an energy storage device, an energy conversion system is electrically connected to the energy storage device to convert the current input to the energy storage device or output from the energy storage device into energy.

[0013] According to a third aspect of this application, a charging network is provided. The charging network includes charging piles; The charging network also includes energy storage devices as described above, and the charging piles are electrically connected to the energy storage devices. Alternatively, the charging network may also include an energy storage system as described above, with the charging piles electrically connected to the energy storage system; Among them, the energy storage device is used to provide power to the charging pile.

[0014] According to a fourth aspect of this application, a handle is provided. The handle is used to adjust the opening degree of a valve structure of an energy storage device as described above, wherein the handle is detachably connected to a first mating structure.

[0015] Because the handle can be installed and removed as needed, multiple valve structures can share the same handle, which significantly saves installation space inside the energy storage device, improves the layout flexibility inside the energy storage device, enhances maintenance convenience and spare parts management efficiency, and reduces overall costs.

[0016] In some embodiments, the handle includes a first segment and a second segment, the first segment being connected to the second segment. The first segment is for the operator to grip, and the end of the second segment away from the first segment is for detachable connection with a first mating structure. The axis of the first segment and the axis of the second segment are on the same straight line, forming a continuous linear operating tool with a simple design and easy manufacturing. Alternatively, the axis of the first segment intersects the axis of the second segment, providing the operator with greater operational flexibility and leverage.

[0017] In some embodiments, the end of the second rod segment away from the first rod segment is detachably inserted into the first mating structure, wherein the first mating structure is configured as a socket, which can improve the stability of the connection between the handle and the valve structure and the ease of operation.

[0018] In some embodiments, the handle further includes a prism segment, with a first rod segment and a second rod segment respectively connected to both ends of the prism segment. Both the prism segment and the second rod segment are inserted into a socket. At least a portion of the socket is configured as a prism hole adapted to the prism segment, and the radial dimension of the prism segment is larger than the radial dimension of the second rod segment. This can improve the connection stability and torque transmission efficiency between the handle and the valve structure.

[0019] In some embodiments, the handle further includes a second positioning member, which is detachably connected to the end of the first rod segment away from the second rod segment. The second positioning member is used to simultaneously insert into both the positioning hole and the stop hole when the positioning hole of the valve structure is aligned with one of the stop holes. Through the synergistic action of the second positioning member with the positioning hole and the stop hole of the valve structure, mechanical positioning of the valve core's opening position is achieved, improving the accuracy and stability of the valve structure's opening adjustment and effectively reducing opening deviations caused by improper operation or external interference.

[0020] In some embodiments, the end wall of the second rod segment away from the first rod segment is provided with a clearance hole. The clearance hole is used to accommodate the end of the second positioning member that passes through the positioning hole. The insertion hole and the positioning hole are coaxially arranged and connected. When the second positioning member passes through the positioning hole, the protruding end of the second positioning member can be accommodated by the clearance hole, which solves the interference problem between the second positioning member and the end wall of the second rod segment of the handle. This allows the second positioning member to be smoothly inserted into the gear hole, the positioning hole, and the clearance hole, thereby achieving reliable positioning of the valve core opening position.

[0021] In some embodiments, the second positioning member includes a body rod segment, a first positioning rod segment, and a second positioning rod segment. The body rod segment, the first positioning rod segment, and the second positioning rod segment are arranged sequentially and connected. The radial dimensions of the body rod segment, the first positioning rod segment, and the second positioning rod segment decrease sequentially. The first positioning rod segment is adapted to be inserted into the stop hole, the second positioning rod segment is adapted to be inserted into the positioning hole, and the end of the second positioning rod extends into the clearance hole. This dual positioning mechanism improves the accuracy and reliability of positioning.

[0022] In some embodiments, the second positioning member further includes a threaded rod segment, with its two ends connected to the body rod segment and the first positioning rod segment respectively. The radial dimension of the threaded rod segment is greater than that of the first positioning rod segment and less than that of the body rod segment. The end wall of the first rod segment away from the second rod segment is provided with a threaded hole, and the threaded rod segment is screwed into the threaded hole, thereby achieving a more stable and reliable connection between the second positioning member and the handle.

[0023] In some embodiments, the valve structure includes a connector having a second mating structure, and a second positioning member is configured to be detachably connected to the second mating structure. That is, the second positioning member can function as a simple hex screwdriver for tightening or loosening the hex screws (i.e., the connector) of the valve structure, thereby reducing the number of tools required for the operator to carry during on-site operations.

[0024] In some embodiments, the first segment of the lever is provided with an anti-slip structure, which is used for the operator to grip and prevent slippage, thereby effectively reducing the occurrence of hand slippage during operation and improving the stability and reliability of the operator when gripping the handle.

[0025] In some embodiments, the anti-slip structure includes anti-slip grooves on the shaft of the first segment; or, the anti-slip structure includes an anti-slip sleeve fixedly covering the shaft of the first segment. Specificity of the anti-slip structure as anti-slip grooves or an anti-slip sleeve can significantly improve the grip stability of the handle under various operating conditions.

[0029] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0030] In the description of this application, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0031] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0032] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0033] In electrochemical energy storage systems, especially inside large energy storage containers, liquid cooling systems are widely used to regulate the temperature of battery devices. Valves (such as butterfly valves) play a crucial role in these systems. Each valve typically has a rotary handle directly integrated with the valve core. This handle, as an integral part of the valve, cannot be independently disassembled or replaced. This design easily leads to the following problems: 1. When the handle is worn due to operation or damaged by external factors, the entire valve must be replaced, significantly increasing spare parts costs and extending maintenance cycles; 2. In energy storage containers with limited space, multiple fixed handles protrude from the valve body surface, occupying additional installation space, severely restricting the layout flexibility of other components, complicating the internal equipment arrangement, increasing maintenance difficulty, and ultimately reducing overall space utilization efficiency and equipment operational reliability.

[0034] Based on the above considerations, embodiments of this application provide an energy storage device and apply it to the assembly of productive energy storage systems and charging networks. A handle is provided for the valve structure in the energy storage device to improve the convenience and efficiency of adjusting and maintaining the valve structure. The core of the energy storage device provided in this application is that the valve head of the valve core is detachably connected to the same handle. This allows one handle to be used to adjust the valve cores of multiple valve structures. In other words, the handle is detached from the valve structure during normal operation of the energy storage device, storing or outputting electrical energy. The handle is only used to adjust the valve core when adjustment or maintenance is needed; it is ready to use immediately and detached after use. This effectively saves internal installation space in the energy storage device cabinet and improves the flexibility of the internal layout. Furthermore, operators can carry the handle with them and use it at any time to adjust and maintain the valve structure, thereby improving the convenience and efficiency of valve structure adjustment and maintenance.

[0035] To illustrate the technical solutions provided by the embodiments of this application, the following detailed description is provided in conjunction with specific drawings and embodiments.

[0036] According to a first aspect of the embodiments of this application, embodiments of this application provide an energy storage device 100, which is designed for efficient storage and management of electrical energy. The energy storage device 100 can be a small, portable device, such as a convenient battery device used for outdoor camping or by street vendors. The energy storage device 100 can also be a large, fixed, high-power industrial-grade device, such as a large energy storage power station used in a power plant. The energy storage device 100 can be used in energy storage power stations, wind power generation systems, solar power generation systems, mobile power systems, or temporary power supply systems. The energy storage device 100 can store electrical energy as needed and output it at appropriate times. For example, the energy storage device 100 can store electrical energy during off-peak hours and provide power to relevant operators or equipment during peak hours. Other examples include independent power supply energy storage cabinets or containers used on construction sites or in factories, and larger portable energy storage cabinets or containers used at large event venues.

[0037] like Figure 1 As shown, the main structure of the energy storage device 100 provided in the embodiments of this application includes a cabinet 10 for providing physical support and protection. Inside the cabinet 10, multiple battery devices 20 are installed, such as... Figure 1 As shown, these battery devices 20 can be connected in series, parallel, or a hybrid series-parallel configuration (i.e., mixed connection) to achieve the required voltage and capacity, depending on system needs. Figures 1 to 7As shown, the energy storage device 100 also includes a heat exchange mechanism 30. The core function of the heat exchange mechanism 30 is to remove the heat generated during the operation of the battery device 20 through a circulating heat exchange medium. The heat exchange mechanism 30 includes a supply section 31, multiple heat exchange sections 21, and multiple valve structures 32. The heat exchange sections 21 are configured to be thermally connected to the battery device 20 to achieve precise temperature control of the battery device 20. The supply section 31 and the heat exchange sections 21 are connected through the valve structures 32 and a pipeline 22. The supply section 31 is responsible for providing and driving the circulating flow of the heat exchange medium. The multiple valve structures 32 are correspondingly arranged with the multiple heat exchange sections 21, so that the flow rate of the heat exchange medium of each battery device 20 can be independently controlled, so that each battery device 20 can obtain a suitable cooling effect to maintain the battery device 20 at its optimal operating temperature. The valve structure 32 includes a valve body 321 and a valve core 322. The valve body 321 serves as the outer shell of the valve structure 32, forming a fluid channel inside and providing installation space for the valve core 322. The valve body 321 connects the heat exchange section 21 and the supply section 31. The valve body 321 and the heat exchange section 21, and the valve body 321 and the supply section 31 are respectively connected by pipes 22, and the supply section 31 and the heat exchange section 21 are also connected by pipes 22, forming a channel for the flow of the heat exchange medium, thus forming a closed cooling loop. A portion of the valve core 322 is installed inside the valve body 321. The valve core 322 changes the cross-sectional area of ​​the fluid channel by its own movement or rotation, thereby regulating the flow rate of the heat exchange medium. The valve core 322 has a valve head 323 that protrudes from the valve body 321. The valve head 323 has a first mating structure 324 for detachable connection with a handle 33. Multiple valve heads 323 of the valve bodies 321 are configured to be detachably connected to the same handle 33 for external adjustment via the handle 33.

[0038] To facilitate understanding, some technical terms are explained below: Energy storage device 100 refers to a device used to store electrical energy. It typically integrates multiple battery cells (i.e., battery devices 20) and is equipped with corresponding management and auxiliary systems, such as a battery management system (BMS) and a thermal management system (BTMS).

[0039] The battery device 20 refers to the core component of the energy storage device 100 that actually stores and releases electrical energy, and is typically composed of multiple battery cells or battery modules. For example... Figure 3As shown, the battery device 20 also includes a main body 23, a cover 24, and multiple battery cells 25. The cover 24 closes to the opening end of the main body 23, and the main body 23 and the cover 24 close to form an assembly space 26. The multiple battery cells 25 are electrically connected in series, parallel, or mixed and are arranged in an array within the assembly space 26. The multiple battery cells 25 are used to store electrical energy or supply power.

[0040] The heat exchange mechanism 30 refers to the system used for temperature management of the battery device 20 (i.e., the main component of the thermal management system), which absorbs or releases heat by circulating heat exchange medium to maintain the battery device 20 within a suitable operating temperature range.

[0041] The supply section 31 refers to the component in the heat exchange mechanism 30 that is responsible for providing or recovering the heat exchange medium, such as a pump, a storage tank, or a distribution manifold.

[0042] The heat exchange section 21 refers to the component in the heat exchange mechanism 30 that directly or indirectly exchanges heat with the battery device 20, such as a cold plate, heat sink, or cooling coil.

[0043] Valve structure 32 refers to the component used to control the flow direction and flow rate of the heat exchange medium in the pipeline 22. The flow of the heat exchange medium is controlled by adjusting its opening degree.

[0044] Valve body 321 refers to the main body of valve structure 32, which forms a flow channel for heat exchange medium and houses valve core 322.

[0045] Valve core 322 refers to the moving part in valve structure 32 that actually controls the flow of heat exchange medium, and changes in its position or angle change the opening of the channel.

[0046] The valve head 323 is a part of the valve core 322, which protrudes from the valve body 321 and is used to connect with external operating tools to drive the valve core 322 to move.

[0047] The first mating structure 324 refers to a connection interface of a specific shape or structure provided on the valve head 323, which is used for a detachable mechanical connection with the handle 33.

[0048] The handle 33 is a tool used to operate the valve structure 32. It is detachably connected to the first mating structure 324 to rotate or move the valve core 322, thereby adjusting the opening degree of the valve structure 32.

[0049] The energy storage device 100 can be configured as a containerized energy storage system, integrating a battery unit 20 and a heat exchange mechanism 30 for temperature management. The battery unit 20 can consist of multiple battery modules, such as lithium-ion battery modules or flow battery modules. The heat exchange mechanism 30 can be designed as a liquid cooling system or an air cooling system to meet different heat dissipation requirements.

[0050] The supply section 31 of the heat exchange mechanism 30 can be a circulating pump for driving the flow of the heat exchange medium, or a storage tank for storing the heat exchange medium. Multiple heat exchange sections 21 can be configured as cold plates corresponding to multiple battery devices 20, or as cooling coils surrounding the battery devices 20. Multiple valve structures 32 can be configured as ball valves, gate valves, or butterfly valves for controlling the flow direction and flow rate of the heat exchange medium. The thermal connection between the heat exchange section 21 and the battery device 20 can be achieved in various ways. For example, the heat exchange section 21 can be directly attached to the surface of the battery device 20, and the heat transfer efficiency can be enhanced by thermally conductive pads or thermally conductive gels. Alternatively, the heat exchange section 21 can be integrated inside the battery device 20, allowing the heat exchange medium to flow directly through channels inside the battery device 20. The communication between the supply section 31 and the heat exchange section 21 can be achieved through a pipe 22, which can be a metal pipe or a flexible hose. The valve structure 32 is installed on the pipeline 22 to control the flow of heat exchange medium from the supply section 31 to the heat exchange section 21, or from the heat exchange section 21 back to the supply section 31.

[0051] To enable independent control of each heat exchanger 21, multiple valve structures 32 can be configured one-to-one with each heat exchanger 21. For example, each battery device 20 can be equipped with an independent valve structure 32 for fine-tuning of the temperature of a single battery device 20.

[0052] The basic components of valve structure 32 include valve body 321 and valve core 322. Valve body 321 is the outer shell of valve structure 32, typically made of cast or forged metal. Valve core 322 is the moving part inside valve structure 32, and its movement changes the cross-sectional area of ​​the fluid passage. Valve body 321 can be connected to pipes 22 connected to heat exchange section 21 and supply section 31 via threaded connections, flange connections, or welding, thereby integrating valve structure 32 into the flow path of the heat exchange medium. Channels for the flow of heat exchange medium are formed inside valve body 321 and at the connection between valve body 321 and external pipes 22. These channels allow the heat exchange medium to flow smoothly from supply section 31 through valve structure 32 to heat exchange section 21, or vice versa. A portion of the valve core 322 is installed inside the valve body 321, supported and guided, for example by bearings or seals, allowing the valve core 322 to rotate or move linearly within the valve body 321 to open or close the fluid passage. The portion of the valve core 322 extending out of the valve body 321 forms the valve head 323. The valve head 323 allows an external operating tool (i.e., handle 33) to contact and drive the valve core 322, thereby adjusting the opening degree of the valve structure 32. The valve head 323 is provided with a first mating structure 324, which can take various forms, such as a groove with a specific geometry, like a square hole, hexagonal hole, or cross groove; or a raised pin, such as a flat shaft or a keyed round shaft. The first mating structure 324 is designed to mechanically connect with a corresponding mating structure on the handle 33 and is detachable, meaning the handle 33 can be installed on the valve head 323 for operation when needed and removed after operation. To achieve versatility and convenience of operation, the first mating structure 324 provided on the valve head 323 of the multiple valve bodies 321 inside the energy storage device 100 is designed as a standardized connection interface. This means that a handle 33 can be compatible with all these standardized first mating structures 324, thereby enabling a handle 33 to operate multiple valve structures 32.

[0053] By designing the handle 33 to be detachably connected to the valve head 323 of the valve structure 32, and enabling multiple valve structures 32 to share the same handle 33, this application effectively solves the problem of fixed handles occupying a large amount of space in traditional energy storage devices. This helps improve the layout flexibility within the energy storage device 100 and saves equipment installation space. Simultaneously, since the handle 33 can be installed and removed as needed, it helps improve the convenience of maintenance operations and increase maintenance efficiency.

[0054] In some embodiments of this application, such as Figure 2 , Figures 4 to 7As shown, the valve structure 32 also includes a sleeve 325. The sleeve 325, as a tubular or annular structural component, is connected to the valve body 321. The sleeve 325 can be fixedly connected to the valve body 321 using various methods such as threaded connection, snap-fit ​​connection, welding, or integral molding. The valve head 323 is rotatably inserted through the sleeve 325. The sleeve 325 has multiple position holes 326, which are circumferentially spaced around the axis of the sleeve 325, thus forming a series of preset adjustment positions. Each position hole 326 corresponds to a specific opening state of the valve core 322. The circumferential sidewall of the valve head 323 has a positioning hole 327, which is configured such that when the valve head 323 rotates, the positioning hole 327 aligns with the position hole 326 on the sleeve 325 to indicate the opening degree of the valve core 322 relative to the valve body 321. Furthermore, when the positioning hole 327 is aligned with a certain position hole 326, the rotational position of the valve head 323 can be locked by inserting a positioning element (such as a pin or latch), thereby precisely fixing the opening degree of the valve core 322 relative to the valve body 321. This allows the operator to adjust the valve core 322 to preset, discrete opening positions as needed, achieving precise graded control of the heat exchange medium flow rate.

[0055] Through the above technical solution, the valve structure 32 is provided with a sleeve 325, a stop hole 326, and a positioning hole 327, providing a repeatable mechanical positioning mechanism for adjusting the opening of the valve structure 32. When the valve head 323 rotates, the positioning hole 327 on the circumferential side wall of the valve head 323 can be aligned with one of the multiple preset stop holes 326 on the sleeve 325, thereby achieving graded control of the opening of the valve core 322 relative to the valve body 321. This reduces the uncertainty caused by adjustment based solely on feel or visual judgment, improves the accuracy of heat exchange medium flow control, and thus improves the temperature management accuracy and stability of the battery device 20. Furthermore, this mechanical positioning method allows operators to quickly and accurately adjust the valve opening to the required preset state, simplifying the operation process, reducing the risk of misoperation, and helping to achieve consistency in the opening between different valve structures 32, thereby improving the operational reliability and maintenance efficiency of the entire energy storage device 100.

[0056] In some embodiments of this application, such as Figure 5 As shown, the valve structure 32 also includes a first positioning member 329, wherein the first positioning member 329 is a mechanical component used to fix the valve core 322 at a specific opening position, that is, the first positioning member 329 is inserted into one of the position holes 326 and the corresponding positioning hole 327.

[0057] The function of the first positioning element 329 is to provide additional locking or limiting between the valve core 322 and the valve body 321, thereby reducing the possibility of accidental rotation or displacement of the valve core 322 relative to the valve body 321 at the set position. The first positioning element 329 can take various forms, such as a pin, latch, bolt, or snap-fit. The material of the first positioning element 329 is selected from metals or engineering plastics with a certain degree of hardness and wear resistance to provide reliability during long-term use. In some embodiments, the first positioning element 329 can be designed with a tapered end for easy insertion and removal; or it can be designed with a spring-loaded mechanism to achieve automatic locking or unlocking.

[0058] The aforementioned "insertion" refers to inserting the first positioning member 329 into the through hole formed by the stop hole 326 and the positioning hole 327. This allows the first positioning member 329 to pass through both the stop hole 326 on the sleeve 325 and the positioning hole 327 on the valve head 323. The valve head 323 is mechanically locked at a specific angular position determined by the alignment of the stop hole 326 and the positioning hole 327, thereby fixing the opening degree of the valve core 322. Insertion can be performed manually or with auxiliary tools. To improve the stability of the insertion, the first positioning member 329 is fitted with a tight fit or a clearance fit with the stop hole 326 and the positioning hole 327 to reduce wobbling.

[0059] By simultaneously inserting the first positioning member 329 into the stop hole 326 of the sleeve 325 and the positioning hole 327 of the valve head 323, the valve head 323 is mechanically fixed in a preset rotational position. This improves the stability of the valve core 322's opening position relative to the valve body 321, effectively reducing the possibility of accidental rotation or movement of the valve core 322 due to vibration, impact, or accidental contact during the operation of the energy storage device 100. This ensures that the flow rate of the heat exchange medium is always maintained at a set optimal level, thereby maintaining the stable operating temperature of the battery device 20 and improving the overall operational reliability and thermal management efficiency of the energy storage device 100.

[0060] It should be noted that in some embodiments, the positional stability of the valve core 322 can also be achieved through damping between it and the valve body 321. In such embodiments, the first positioning member 329 can be inserted into the through hole formed by the stop hole 326 and the positioning hole 327 to determine that the valve core 322 has rotated into position, thereby achieving the purpose of controlling the flow rate of the heat exchange section 21. After the valve core 322 has rotated into position, the first positioning member 329 can be removed or left in the stop hole 326 and the positioning hole 327. When the first positioning member 329 is left in the stop hole 326 and the positioning hole 327, combined with the damping between the valve core 322 and the valve body 321, the positional stability of the valve core 322 relative to the valve body 321 is further improved.

[0061] In some embodiments of this application, such as Figure 2 , Figures 4 to 7 As shown, the valve head 323 is housed within the sleeve 325, meaning the valve head 323 is enclosed by the sleeve 325, maintaining the overall compactness of the valve structure 32. A first mating structure 324 is located on the circumferential sidewall of the valve head 323. The first mating structure 324 can take various forms, such as a groove, protrusion, keyway, or insertion hole. The function of the first mating structure 324 is to provide a standardized connection interface, enabling the handle 33 to connect stably and reliably to the valve head 323, thereby transmitting rotational torque to adjust the opening of the valve core 322. Since the valve head 323 is enclosed by the sleeve 325, to address the issue of the first mating structure 324 being obstructed by the sleeve 325, the sleeve 325 is provided with an avoidance notch 328, such as... Figure 2 , Figure 5 and Figure 7 As shown, the clearance notch 328 can be rectangular, circular, elliptical, or other geometric shapes suitable for the handle 33 to pass through. A first mating structure 324 is provided corresponding to the clearance notch 328. The function of the first mating structure 324 is to provide a channel for the handle 33 to enter the interior of the sleeve 325; that is, the clearance notch 328 is used for the handle 33 to pass through for detachable connection with the first mating structure 324. When the valve head 323 is rotated to a specific position, the first mating structure 324 is exposed at the clearance notch 328, thereby allowing the handle 33 to be inserted or detachably connected. The handle 33 extends into the interior of the sleeve 325 through the clearance notch 328 and is detachably connected to the first mating structure 324 on the circumferential sidewall of the valve head 323 through insertion, engagement, or screwing.

[0062] In some embodiments of this application, the first mating structure 324 is configured as a socket, which is coaxially arranged and connected to the positioning hole 327, such as... Figure 2 As shown. Specifically, the first mating structure 324 is configured as a socket, that is, a groove or hole is formed on the valve head 323 to receive the corresponding insertion part of the handle 33. The socket can be a circular, square, or polygonal cross-sectional shape, and its size and depth must match the insertion end of the handle 33. Through the socket, the connection between the handle 33 and the valve head 323 can be tighter and more stable, effectively reducing the risk of shaking or falling off during operation, thereby improving the reliability of operation. The socket and the positioning hole 327 are coaxially arranged, which means that the geometric axis of the socket and the geometric axis of the positioning hole 327 coincide in space, so that the socket and the positioning hole 327 always maintain relative alignment when the valve head 323 rotates.

[0063] As an example, the insertion hole and the positioning hole 327 are connected, meaning that the internal space of the insertion hole and the internal space of the positioning hole 327 are interconnected. This allows the positioning structure on the end of the handle 33 inserted into the insertion hole (e.g., the positioning pin on the end of the handle 33) to be inserted from the entrance of the insertion hole and further into the positioning hole 327 and the position hole 326, thereby quickly positioning the opening degree of the valve core 322 relative to the valve body 321. After selecting a specific position, the handle is removed, and then the first positioning member 329 is inserted into the position hole 326 and the positioning hole 327, thereby reliably locking the opening degree of the valve core 322 and improving the reliability of positioning.

[0064] In some embodiments of this application, the valve head 323 of the energy storage device 100 is housed within the sleeve 325, meaning the valve head 323 is covered by the sleeve 325. This helps protect the valve head 323 from external environmental influences or accidental impacts, while also making the overall appearance of the valve structure 32 more regular. To facilitate the connection between the handle 33 and the valve head 323, the end of the sleeve 325 away from the valve body 321 is configured as an open end, providing a direct channel for the connection between the handle 33 and the valve head 323. The open end can be circular, square, or other geometry suitable for inserting the handle 33, and its size should allow the handle 33 to pass through smoothly and mate with the valve head 323. In this embodiment, no additional holes or notches are made on the side wall of the sleeve 325, thereby helping to maintain the structural integrity and strength of the sleeve 325. The first mating structure 324 is located on the end wall of the valve head 323 away from the valve core 322 (i.e., the top or exposed end face of the valve head 323). This allows the first mating structure 324 to be directly exposed or easily accessible through the open end of the sleeve 325 when the valve head 323 is housed within the sleeve 325. The first mating structure 324 can be a socket, protrusion, groove, threaded hole, or any structure capable of detachably connecting with the handle 33, and its specific form should match the corresponding mating structure of the handle 33. The open end is used for the handle 33 to pass through for detachable connection with the first mating structure 324; that is, the open end of the sleeve 325 serves as the entry point for the handle 33 to enter and connect with the first mating structure 324. The handle 33 is inserted through the open end, and the end of the handle 33 is mechanically connected to the first mating structure 324 on the end wall of the valve head 323, such as by plugging, snapping, or screwing, so that the handle 33 can be easily installed and removed, thereby realizing the adjustment of the valve core 322 opening degree, and the handle 33 can be removed when not needed to prevent misoperation or save space.

[0065] Through the above technical solution, the first mating structure 324 is set on the end wall of the valve head 323 and connected through the open end of the sleeve 325. No additional clearance notch needs to be made on the side wall of the sleeve 325, thus effectively maintaining the structural integrity and strength of the sleeve 325 and potentially improving its sealing performance. Furthermore, the connection method of inserting from the top of the sleeve 325 makes the installation and removal of the handle 33 more intuitive and convenient, improving operational ease. The valve head 323 is effectively protected inside the sleeve 325, further enhancing the durability and reliability of the valve structure 32.

[0066] In some embodiments of this application, such as Figure 2 , Figures 4 to 7 As shown, the surface of the end wall of the valve head 323 of the energy storage device 100, away from the valve core 322, is flush with the end face of the sleeve 325. The surface of the end wall of the valve head 323 away from the valve core 322 refers to the visible portion of the valve head 323 on the outside or operable side of the valve body 321. This surface is the main interface for operation or observation by the operator. The surface of this end wall can be designed to be flat, slightly curved, or have a specific texture, depending on actual needs, to optimize the operating feel or visual effect. The end face of the sleeve 325 refers to the outermost part of the sleeve 325 in the direction of the valve head 323, and it is usually flat.

[0067] By employing the aforementioned technical solution, the surface of the end wall of the valve head 323 furthest from the valve core 322 is made flush with the end face of the sleeve 325, resulting in a cleaner and more integrated appearance for the valve structure 32 of the energy storage device 100. This design reduces the risk of the valve head 323 protruding from the sleeve 325 and being susceptible to accidental impacts or scratches, thereby improving the durability and reliability of the valve structure 32 and extending its service life.

[0068] According to a second aspect of this application, embodiments of this application also provide an energy storage system. The energy storage system includes an energy conversion system and an energy storage device 100 as described above. The energy conversion system is connected to the energy storage device 100 to convert energy from current input to or output from the energy storage device 100. The battery device 20 in the energy storage device 100 is used to store electrical energy or provide electrical energy.

[0069] In some embodiments, the energy storage system may include one or more energy storage devices 100 and a power converter system (PCS). The power converter system is used to connect the power generation equipment, the power grid, or the load to the energy storage device 100. The power generation equipment generates electrical energy, the energy storage device 100 stores electrical energy, and the power converter system converts the current input to the energy storage device 100 or the current output from the energy storage device 100 into energy. The electrical energy generated by the power generation equipment can be stored in the energy storage device 100 through the power converter system, and the electrical energy stored in the energy storage device 100 can also be output to the load or the power grid through the power converter system. As an example, the power generation equipment may specifically be a solar panel, a hydroelectric power generation device, a thermal power generation device, a wind power generation device, etc. The specific type of power generation equipment is not limited in this application.

[0070] According to a third aspect of the embodiments of this application, embodiments of this application also provide a charging network, including charging piles.

[0071] In some embodiments, the charging network further includes an energy storage system as described above, with the charging pile electrically connected to the energy storage system, wherein the battery device 20 of the energy storage device 100 of the energy storage system is used to store electrical energy, or the battery device 20 of the energy storage device 100 is used to provide electrical energy to the charging pile.

[0072] In some other embodiments of this application, the charging network further includes an energy storage device 100 as described above, and the charging pile is electrically connected to the energy storage device 100, wherein the battery device 20 of the energy storage device 100 is used to store electrical energy, or the battery device 20 of the energy storage device 100 is used to provide electrical energy to the charging pile.

[0073] The charging pile may have one or more connectors, which are used to connect to the charging interface of the device to be charged (such as an electric vehicle), so as to replenish the energy storage unit (such as the battery of the electric vehicle) of the device to be charged.

[0074] According to a fourth aspect of this application, a handle 33 is provided, such as Figures 4 to 6 , Figures 8 to 9 As shown. The handle 33 is used to adjust the opening degree of the valve structure 32 of the energy storage device 100, the energy storage device 100 of the energy storage system, and the energy storage device 100 of the charging network. Specifically, the handle 33 includes a first rod segment 331 and a second rod segment 332, with the first rod segment 331 connected to the second rod segment 332. The first rod segment 331 is configured for the operator to grip, and the end of the second rod segment 332 away from the first rod segment 331 is configured to be detachably connected to the first mating structure 324, thereby engaging with the valve head 323 during operation to achieve rotational control of the valve core 322.

[0075] By designing the first mating structure 324 as a detachable connection and enabling the handle 33 to operate multiple valve structures 32 in a universal manner, the problem of fixed handles occupying extra space inside the energy storage device 100 is solved. Since the handle 33 can be installed and removed as needed, multiple valve structures 32 can share the same handle 33, significantly saving installation space inside the energy storage device 100, improving the layout flexibility of the energy storage device 100, enhancing maintenance convenience and spare parts management efficiency, and reducing overall costs. This design optimizes the internal space utilization of the energy storage device 100, making more efficient equipment integration and maintenance operations possible in a compact container environment.

[0076] In some embodiments of this application, two structural configurations of the handle 33 are proposed to optimize its operational performance and adaptability. The first structural configuration is as follows: Figures 4 to 6 , Figure 8 As shown, the axis of the first segment 331 of the handle 33 and the axis of the second segment 332 can be configured to be on the same straight line; or, in a second configuration, the axis of the first segment 331 and the axis of the second segment 332 can be configured to intersect.

[0077] When the axis of the first rod segment 331 and the axis of the second rod segment 332 are collinear, the handle 33 presents a straight rod structure. That is, the first rod segment 331 held by the operator and the second rod segment 332, which actually acts on the valve structure 32, extend along the same axis, forming a continuous linear operating tool. This design is simple, easy to manufacture, and, given sufficient operating space, provides a direct and intuitive force transmission path, facilitating the operator's control of the valve structure 32's opening. For example, it could be a cylindrical or polygonal straight rod, with its two ends serving as the gripping and connecting points, respectively.

[0078] When the axis of the first segment 331 intersects the axis of the second segment 332, the handle 33 exhibits a non-linear structure, such as an L-shape, T-shape, or crank shape. That is, the axis of the first segment 331 held by the operator has a spatial angle or offset from the axis of the second segment 332. For example, the first segment 331 can be set perpendicular to the second segment 332, forming an L-shaped handle. This design provides the operator with greater operational flexibility and leverage.

[0079] Through the above technical solutions, the structural configuration of the handle 33 has been optimized, improving its adaptability and ease of operation in different application scenarios. When the axes of the first rod segment 331 and the second rod segment 332 are on the same straight line, the handle 33 has a compact structure and direct operation, making it suitable for occasions with relatively ample space or requiring precise linear operation, thus reducing manufacturing costs and complexity. When the axes of the first rod segment 331 and the second rod segment 332 intersect, the handle 33 can provide a more ergonomic grip angle and a larger torque arm, making it easier and more comfortable for the operator to operate the valve structure 32. Especially when the internal space of the energy storage device 100 is limited or the installation position of the valve structure 32 is inconvenient, this design can effectively avoid obstacles, making it convenient for the operator to operate from the side or a specific angle, thereby improving operating efficiency and enhancing the overall maintainability of the energy storage device 100.

[0080] In some embodiments of this application, such as Figure 8 and Figure 9 As shown, the end of the second segment 332 of the handle 33, away from the first segment 331, is detachably inserted into the first mating structure 324, which is configured as a socket. Specifically, the detachable insertion of the end of the second segment 332 away from the first segment 331 into the first mating structure 324 means that the connection between the handle 33 and the valve structure 32 adopts an insertion-type mechanical coupling method. The end of the second segment 332 is designed to match the shape of the first mating structure 324 for quick and easy insertion and removal. This detachable insertion connection method not only simplifies the operation process, allowing the operator to easily connect the handle 33 to the valve structure 32 that needs adjustment, but also facilitates the removal of the handle 33 when not in use, thereby achieving universal adjustment of multiple valve structures 32 with one handle 33, improving the convenience of equipment maintenance and the efficiency of spare parts management.

[0081] Furthermore, the first mating structure 324 is configured as a socket, which is a groove or hole formed on the valve head 323. The internal shape of the socket corresponds to the end shape of the second rod segment 332. The socket provides clear guidance and limitation for the insertion of the second rod segment 332, improving the alignment efficiency during the connection process and effectively reducing connection difficulties or unstable connections caused by inaccurate alignment. The internal structure of the socket can be designed into various geometric shapes according to actual needs, such as square, hexagonal, D-shaped, or circular with keyways, so as to effectively transmit torque after insertion, thereby achieving precise rotational control of the valve core 322.

[0082] By employing the aforementioned technical solution, the first mating structure 324 is configured as a socket, and the second rod segment 332 of the handle 33 is connected via a detachable insertion method. This enhances the stability of the connection between the handle 33 and the valve structure 32, as well as the ease of operation. The guiding effect provided by the socket allows the operator to quickly and accurately align the handle 33 during connection, reducing the possibility of shaking or misalignment during the connection process, thereby improving the reliability of torque transmission. This stable and easy-to-operate connection method ensures the accuracy and stability of the valve structure 32's opening adjustment, reduces the possibility of adjustment errors or operational interruptions due to loose connections, and improves the overall operational reliability of the energy storage device 100.

[0083] In some embodiments of this application, such as Figure 8 and Figure 9 As shown, the handle 33 also includes a prism segment 335. A first rod segment 331 and a second rod segment 332 are respectively connected to both ends of the prism segment 335. Both the prism segment 335 and the second rod segment 332 are inserted into sockets. At least a portion of the socket is configured as a prism hole adapted to the prism segment 335, and the radial dimension of the prism segment 335 is larger than the radial dimension of the second rod segment 332. Specifically, the prism segment 335 is an intermediate connecting part of the handle 33. The cross-sectional shape of the prism segment 335 is polygonal, such as a square or hexagonal shape. The prism design aims to provide torsional resistance and positioning stability during rotation. The prism segment 335 can be made of metal, high-strength plastic, or other composite materials to provide sufficient mechanical strength and wear resistance to withstand the torque and stress generated during operation. The first rod segment 331 and the second rod segment 332 are respectively connected to the two ends of the prism segment 335. The prism segment 335 serves as a transition part of the handle 33, connecting the first rod segment 331 for the operator to grip and the second rod segment 332 for inserting the valve structure 32. This connection method can be welding, threaded connection, interference fit, or integral molding, etc., to achieve the integrity of the handle 33 and the reliability of torque transmission.

[0084] Furthermore, both the prism segment 335 and the second rod segment 332 are inserted into the socket. This means that when the handle 33 is connected to the valve structure 32, not only the second rod segment 332, but also part or all of the prism segment 335 will be inserted into the first mating structure 324 (socket) of the valve structure 32. This double insertion design increases the contact area and mating depth between the handle 33 and the valve structure 32, thereby improving the stability of the connection. At least a portion of the socket is configured as a prism hole adapted to the prism segment 335. That is, the interior of the first mating structure 324 (socket) of the valve structure 32 is not entirely circular, but at least a portion is machined into a prism-shaped hole that matches the cross-sectional shape of the prism segment 335. For example, if the prism segment 335 is square, the corresponding portion of the socket is also a square hole. This mating of the prism hole and the prism segment 335 can effectively transmit rotational torque and prevent the handle 33 from spinning freely or slipping during rotation, thus improving the adjustment stability of the valve core 322. Furthermore, the radial dimension of the prism segment 335 is larger than that of the second rod segment 332, meaning the prism segment 335 is more robust than the second rod segment 332. This allows the prism segment 335 to provide a larger torsional cross-section, enhancing the overall strength and rigidity of the handle 33. When the prism segment 335 is inserted into the prism hole, its larger radial dimension creates a tight fit with the prism hole, further improving the stability of the connection and torque transmission efficiency, and providing the handle 33 with stronger bending and shear resistance.

[0085] Through the above technical solution, a prism segment 335 is designed in the handle 33, and at least a portion of the insertion hole is set as a prism hole adapted to the prism segment 335. Furthermore, the radial dimension of the prism segment 335 is larger than the radial dimension of the second rod segment 332. This improves the connection stability and torque transmission efficiency between the handle 33 and the valve structure 32. When the handle 33 is inserted into the insertion hole, the tight fit between the prism segment 335 and the prism hole reduces the possibility of wobbling, slippage, or free rotation that may occur when the handle 33 rotates to adjust the opening of the valve core 322, thus ensuring the stability of the adjustment operation. Moreover, the larger radial dimension of the prism segment 335 enhances the overall strength of the handle 33, reducing the risk of damage to the handle 33 or valve structure 32 due to uneven force, extending the service life of the equipment, and improving operational reliability.

[0086] In some embodiments of this application, such as Figures 4 to 6 , Figure 10As shown, the handle 33 also includes a second positioning member 34, which is detachably connected to the end of the first rod segment 331 away from the second rod segment 332. The second positioning member 34 is used to simultaneously insert into both the positioning hole 326 and the positioning hole 327 when the positioning hole 327 of the valve structure 32 is aligned with one of the stop holes 326. Specifically, the second positioning member 34 is an auxiliary positioning structure designed to work in conjunction with the positioning hole 327 and the stop hole 326 on the valve structure 32 to lock the valve core 322. The second positioning member 34 can be a pin or column with a specific shape and size, and the material can be a high-strength, wear-resistant metal or engineering plastic to ensure durability during frequent insertion, removal, and positioning. For ease of operation, the end of the second positioning member 34 can be designed to be tapered or chamfered to facilitate smooth insertion of the second positioning member 34 into the positioning hole 327 and the stop hole 326.

[0087] The second positioning element 34 and the first rod segment 331 of the handle 33 are detachably connected. For example, the end of the first rod segment 331 may have a threaded hole, and the second positioning element 34 has a corresponding threaded rod segment, which can be connected by screwing in and out; or, a snap-fit, magnetic, or pin-type connection can be used to facilitate the installation or removal of the second positioning element 34. Positioning the second positioning element 34 at the end of the first rod segment 331 away from the second rod segment 332 allows the operator to easily remove the second positioning element 34 when holding the first rod segment 331 for valve adjustment, and then align and insert it into the positioning hole 327 and the stop hole 326 of the valve structure 32, thereby quickly positioning the opening position of the valve core 322.

[0088] When adjusting the opening of valve structure 32, the operator first inserts the second rod section 332 of handle 33 into the first mating structure 324 (i.e., the insertion hole) of valve head 323, and then rotates handle 33 to drive valve core 322 to rotate. When the positioning hole 327 on valve core 322 is rotated to align with a preset position hole 326 on valve body 321 (or sleeve 325), the operator can remove the second positioning member 34 on handle 33 and insert it into positioning hole 327 and position hole 326. The diameter of the second positioning member 34 should match the inner diameter of these two holes. Once the second positioning member 34 is inserted into place, it provides mechanical locking, effectively fixing the position of valve core 322 relative to valve body 321, thereby positioning the opening of valve structure 32 at the required position, thus completing the adjustment operation of valve structure 32. Then, the second positioning member 34 is removed from the positioning hole 327 and the gear hole 326 and reconnected to the first rod section 331. Next, the first positioning member 329 is inserted into the positioning hole 327 and the gear hole 326 to lock the opening position of the valve structure 32. Then the handle 33 can be removed.

[0089] Through the above technical solution, when adjusting the opening of the valve structure 32, the handle 33 achieves mechanical positioning of the valve core 322's opening position through the coordinated action of the second positioning member 34 with the positioning hole 327 and the stop hole 326 of the valve structure 32. This improves the accuracy and stability of the valve structure 32's opening adjustment, effectively reducing opening deviations caused by improper operation or external interference, thereby enabling the energy storage device 100 to achieve optimal heat exchange efficiency and operating performance. Furthermore, the detachable design of the second positioning member 34 not only facilitates its own maintenance and replacement but also provides operators with flexible options. That is, when positioning the valve core 322's opening position is not required or continuous adjustment is needed, the second positioning member 34 can be omitted, thus improving the versatility and ease of operation of the handle 33.

[0090] In some embodiments of this application, such as Figure 9 As shown, the end wall of the second rod segment 332 of the handle 33, away from the first rod segment 331, is provided with a clearance hole 334. The clearance hole 334 is used to accommodate the end of the second positioning member 34 that passes through the positioning hole 327. The insertion hole and the positioning hole 327 are coaxially arranged and connected. Specifically, the clearance hole 334 is a hole provided on the end wall of the second rod segment 332 of the handle 33, away from the first rod segment 331. The function of the clearance hole 334 is to provide a accommodating space for the second positioning member 34 when it is inserted into and passes through the positioning hole 327 of the valve structure 32, preventing physical interference between the protruding part of the second positioning member 34 and the end wall of the second rod segment 332 of the handle 33. The size and depth of the clearance hole 334 should be designed according to the protruding length of the second positioning member 34, so that the second positioning member 34 can be inserted into place while the handle 33 can be stably connected. The insertion hole (i.e., the first mating structure 324) and the positioning hole 327 are coaxially arranged and connected, meaning that the central axes of these two holes coincide and are connected. Thus, when the second rod segment 332 of the handle 33 is inserted into the insertion hole, the positioning hole 327 is located in the central area of ​​the end wall of the second rod segment 332 of the handle 33, thereby aligning the clearance hole 334 with the positioning hole 327, providing an accurate path for the insertion of the second positioning member 34. This simplifies the positioning operation and improves the accuracy and reliability of positioning.

[0091] Through the above technical solution, a clearance hole 334 is provided on the end wall of the second rod segment 332 of the handle 33, and the insertion hole and the positioning hole 327 are coaxially arranged and connected. When the second positioning member 34 passes through the positioning hole 327, the protruding end of the second positioning member 34 can be accommodated by the clearance hole 334, which solves the interference problem between the second positioning member 34 and the end wall of the second rod segment 332 of the handle 33, so that the second positioning member 34 can be smoothly inserted into the gear hole 326, the positioning hole 327 and the clearance hole 334, thereby realizing reliable positioning of the valve core 322 opening position.

[0092] In some embodiments of this application, such as Figure 10 As shown, the second positioning member 34 includes a body rod segment 341, a first positioning rod segment 342, and a second positioning rod segment 343. The body rod segment 341, the first positioning rod segment 342, and the second positioning rod segment 343 are arranged sequentially and connected. The radial dimensions of the body rod segment 341, the first positioning rod segment 342, and the second positioning rod segment 343 decrease sequentially. The first positioning rod segment 342 is used to fit into the stop hole 326, and the second positioning rod segment 343 is used to fit into the positioning hole 327. The end of the second positioning rod extends into the clearance hole 334. Specifically, the second positioning member 34 is designed with a segmented structure rather than a single rod, allowing it to better adapt to holes of different diameters and achieve multi-level positioning. The body rod segment 341 is the main body of the second positioning member 34, providing sufficient structural strength. The first positioning rod segment 342 and the second positioning rod segment 343 extend from the main body rod segment 341, forming a progressively smaller structure. The main body rod segment 341 has the largest radial dimension; the radial dimension of the first positioning rod segment 342 is smaller than that of the main body rod segment 341, allowing it to be inserted into the stop hole 326; the radial dimension of the second positioning rod segment 343 is the smallest, allowing it to be further inserted into the positioning hole 327. This progressively smaller design allows the second positioning component 34 to adapt to holes of different diameters, achieving a tight fit, reducing wobbling, and thus improving the accuracy and stability of positioning.

[0093] The first positioning rod segment 342 is the part of the second positioning member 34 responsible for engaging with the gear shift hole 326. It can be smoothly inserted into the gear shift hole 326 and provides sufficient engagement accuracy. The second positioning rod segment 343 is the part of the second positioning member 34 responsible for engaging with the positioning hole 327. The second positioning rod segment 343 can pass through the gear shift hole 326 and be further inserted into the positioning hole 327. This dual positioning mechanism, where the first positioning rod segment 342 engages with the gear shift hole 326 and the second positioning rod segment 343 engages with the positioning hole 327, improves the accuracy and reliability of positioning.

[0094] In some embodiments of this application, such as Figure 10As shown, the second positioning member 34 also includes a threaded rod segment 344, with its two ends connected to the main body rod segment 341 and the first positioning rod segment 342, respectively. Specifically, the threaded rod segment 344 is a component of the second positioning member 34, used to mate with the threaded hole 333 to achieve a detachable threaded connection. The first rod segment 331 has a threaded hole 333 on its end wall away from the second rod segment 332. The threaded hole 333 is an internal thread structure provided on the end wall of the first rod segment 331 of the handle 33, used to thread-mate with the threaded rod segment 344 of the second positioning member 34. This allows the second positioning member 34 to be easily installed at the end of the handle 33 and form a single unit with the handle 33, ensuring that the second positioning member 34 is securely fixed to the handle 33 and is not easily loosened or detached.

[0095] The radial dimension of the threaded rod segment 344 is larger than that of the first positioning rod segment 342 and smaller than that of the body rod segment 341. The larger radial dimension of the threaded rod segment 344 provides sufficient thread engagement area and connection strength, reducing the possibility of damage or loosening due to force during operation. Furthermore, the smaller radial dimension of the threaded rod segment 344 allows the body rod segment 341 to serve as a more robust gripping or supporting part and provides sufficient material thickness for the threaded connection.

[0096] Through the above technical solution, the threaded section 344 of the second positioning component 34 is screwed into the threaded hole 333 of the first section 331 of the handle 33, achieving a more stable and reliable connection between the second positioning component 34 and the handle 33. The threaded connection reduces the possibility of the second positioning component 34 loosening or accidentally falling off during operation due to force, thereby improving stability. Furthermore, the threaded connection method, while providing a strong connection, also retains detachability, making the installation and removal of the second positioning component 34 more convenient, facilitating maintenance and replacement.

[0097] In some embodiments of this application, such as Figure 10 As shown, the second positioning rod segment 343 of the second positioning member 34 is configured as a hexagonal prism, and correspondingly, the positioning hole 327 can be configured as a hexagonal prism hole or a round hole adapted to the hexagonal prism. For example, Figure 2 , Figures 4 to 7As shown, the valve structure 32 includes a connector 330 with a second mating structure 330'. For example, the connector 330 is a hexagonal socket head cap screw assembly, and the second mating structure 330' is the hexagonal countersunk hole of the hexagonal socket head cap screw in the assembly. The second positioning rod segment 343 of the second positioning member 34 is configured to be detachably connected to the second mating structure 330'. In other words, the hexagonal prism-shaped second positioning rod segment 343 can be used as a hexagonal screwdriver for the valve structure 32. In this embodiment, the hexagonal prism size of the second positioning rod segment 343 not only serves for positioning but also matches the size of the hexagonal countersunk hole of any hexagonal socket head cap screw that may exist inside or near the valve structure 32. This allows it to function as a simple hexagonal screwdriver for tightening or loosening the hexagonal socket head cap screws in the valve structure 32, thereby reducing the types of tools required for on-site operation.

[0098] In some embodiments of this application, such as Figures 4 to 6 , Figure 8 As shown, the first segment 331 of the handle 33 has an anti-slip structure 336 on its shaft. This anti-slip structure 336 is designed to prevent slippage during operation. Specifically, the shaft of the first segment 331 is the part of the handle 33 that the operator directly grips. Its shape and size are typically designed to be ergonomic, allowing the operator to apply operating force comfortably and stably. The anti-slip structure 336 is located on the surface of this shaft to enhance grip performance. The anti-slip structure 336 is a structure located on the surface of the first segment 331. Its function is to increase the friction when the operator grips the handle, thereby effectively reducing hand slippage during operation and improving the stability and reliability of the operator's grip on the handle 33. This structure can be implemented in various ways. For example, a texture with a certain degree of roughness can be formed on the shaft surface, such as straight lines, grid patterns, spiral patterns, or dotted protrusions, to increase the surface friction coefficient; or, a high-friction material, such as an anti-slip sleeve made of elastomers like rubber or silicone, can be applied to the outside of the shaft. The anti-slip structure 336 is designed to improve grip stability and comfort, effectively reducing hand slippage even under adverse operating conditions such as when large torque is required or when the operator's hands are wet or oily.

[0099] In some embodiments of this application, the anti-slip structure 336 of the handle 33 may include anti-slip textures on the shaft of the first segment 331; or, the anti-slip structure 336 may include an anti-slip sleeve fixedly covering the shaft of the first segment 331. Specifically, the anti-slip texture refers to a texture with a certain depth and shape formed on the surface of the shaft of the first segment 331 by means of machining, molding, or laser etching, and can be in various forms such as straight lines, grid patterns, spiral patterns, dot patterns, or irregular patterns. The function of the anti-slip texture is to increase the friction between the operator's hand and the first segment 331, and by increasing the roughness of the contact surface, effectively reduce the slippage of the hand when gripping, thereby improving the stability and reliability of operation. On the other hand, the anti-slip sleeve refers to an additional component that is fitted or covered over the outside of the first shaft segment 331. The anti-slip sleeve is made of a material with a high coefficient of friction and good elasticity, such as rubber, silicone, soft plastic, or composite materials. The anti-slip sleeve can be fixed to the first shaft segment 331 by interference fit, bonding, injection molding, or snap-fit. The surface of the anti-slip sleeve can be designed with various textures or shapes to further enhance the anti-slip effect and grip comfort. The anti-slip sleeve not only provides excellent anti-slip performance but also absorbs vibrations during operation to a certain extent, providing a more comfortable grip.

[0100] By using the above technical solutions, the anti-slip structure 336 is concretized into anti-slip textures or anti-slip sleeves, which can significantly improve the grip stability of the handle 33 under various operating conditions.

[0101] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
