Description

Technical Field

[0001] This utility model relates to the field of electrical connector technology, and in particular to a wiring device for a battery management system of an electrochemical energy storage power station. Background Technology

[0002] As an important component of the new power system, the safe and stable operation of electrochemical energy storage power stations is of paramount importance. The battery management system is the core of ensuring the efficient and safe operation of the energy storage unit. It involves a large amount of electrical energy collection and transmission, which needs to be achieved through stable and reliable wiring devices. Wiring devices are usually used to connect battery clusters to busbars or energy conversion systems.

[0003] Since energy storage systems typically operate under conditions of high current, the current flowing through the terminals of the wiring device will generate significant Joule heat due to contact resistance. If this heat cannot be dissipated in a timely and effective manner, the temperature of the wiring terminals will continue to rise. This will not only accelerate the aging of the terminal materials and increase the connection resistance, but in extreme cases, it may even cause the connection point to melt, leading to a serious safety accident such as a fire.

[0004] Meanwhile, due to the need for safety inspections, troubleshooting, or system upgrades, the terminals need to be regularly maintained or replaced. In traditional wiring devices, the terminals are mostly fixed by bolts. When disassembling and installing them in the compact energy storage cabinet, the operation is very inconvenient, requires special tools, and consumes a lot of time, which seriously affects the operation and maintenance efficiency and availability of the power station.

[0005] In summary, existing wiring devices often suffer from trade-offs in their design, making it difficult to simultaneously meet the requirements of efficient heat dissipation under high current and convenient and quick maintenance. As a result, in practical applications, either complex and difficult-to-disassemble designs are adopted to ensure heat dissipation, or thermal management performance is sacrificed for ease of maintenance. The contradiction between the two constitutes a technical problem that urgently needs to be solved.

[0006] Therefore, this utility model proposes a wiring device for an electrochemical energy storage power station battery management system to address the shortcomings of the prior art. Utility Model Content

[0007] In view of the problems existing in the wiring device of the battery management system of electrochemical energy storage power station, such as the complex disassembly and assembly structure of the wiring terminals during maintenance, the long time consumption, poor heat dissipation during operation, and the safety hazards, this utility model aims to provide a wiring device for the battery management system of electrochemical energy storage power station with an improved structure that can effectively solve the above problems.

[0008] This utility model provides a wiring device for an electrochemical energy storage power station battery management system, including: a housing, a mounting plate, wiring terminals, a disassembly mechanism, and a heat dissipation mechanism; The disassembly mechanism includes a limiting plate fixed to one end of the mounting plate and a clamping block slidably connected to the other end of the mounting plate. The mounting plate has a sliding groove, and the bottom of the clamping block has a slider that slides in cooperation with the sliding groove. The clamping block is provided with a locking block, and the locking block has a slot and is rotatably connected to a rotating block. Furthermore, the terminal block is assembled by being releasably clamped and fixed between the limiting plate and the clamping block. The rotating block is used to lock or unlock the clamping block by cooperating with the slot. The fan in the heat dissipation mechanism is installed on one side of the housing, and the guide plate is fixed to the inner wall of the housing. Through this structural combination, the terminal block can be quickly disassembled and assembled, and heat dissipation can be achieved.

[0009] Preferably, the cross-sectional shape of the slider and the cross-sectional shape of the groove are T-shaped and mutually complementary. This T-shaped structure provides a reverse limiting effect when the clamping block slides, which can effectively prevent the clamping block from tilting upward or detaching from the mounting plate when subjected to force, thus ensuring the stability and safety of operation.

[0010] Preferably, the rotating block is disposed at the top of the locking block, and by rotating at a predetermined angle on the inner wall of the slot, the clamping block can be locked or unlocked by moving along the length of the slide. The locking and unlocking operations can be completed by rotating at a small angle, which simplifies the disassembly and installation steps and improves maintenance efficiency.

[0011] Preferably, the heat dissipation mechanism further includes a protective cover, which is placed on the outside of the fan. The protective cover can not only prevent external objects from accidentally touching the high-speed rotating fan blades, causing equipment damage or personal injury, but also provide a structural basis for the subsequent installation of a dustproof net.

[0012] Preferably, the heat dissipation mechanism further includes a dustproof net, which is fixed to the inner wall of the protective cover. The dustproof net can effectively block dust and willow catkins in the air from entering the device, preventing impurities from accumulating on the terminals or circuit boards, affecting heat dissipation or causing short circuits, and extending the service life of the device.

[0013] Preferably, the guide plate is located downstream of the airflow path of the fan and is inclined. The inclined plate surface can scientifically disperse and redirect the concentrated airflow, so that the airflow can be evenly blown to the inside of the device, especially the areas with high heat generation, such as the wiring terminals, avoiding local hot spots and improving the overall heat dissipation effect.

[0014] Preferably, the wiring device of the battery management system of the electrochemical energy storage power station further includes a wire frame, which is fixedly connected to the front and rear ends of the mounting plate. The wire frame is used to organize, group and support the wires of the introduction device, so that the internal wiring is neat and orderly, avoiding stress on the connection point due to the weight or vibration of the wires, and enhancing the long-term reliability of the connection.

[0015] Preferably, the clamping block is provided with two locking blocks, and the two locking blocks are symmetrically distributed on the top of the clamping block. The symmetrical arrangement makes the force applied to the clamping block more balanced when locking, and can provide a stable locking force from two points at the same time, ensuring that the clamping block will not be displaced under vibration conditions.

[0016] This utility model has the following beneficial effects: 1. This utility model solves the problem of complex disassembly and assembly structure and long time consumption when repairing wiring terminals in the prior art by setting a disassembly mechanism composed of a limiting plate, a clamping block that can slide in the slide groove, a locking block and a rotating block for locking the clamping block.

[0017] 2. This utility model solves the problem of overheating and damage to components caused by heat accumulation in the wiring device, which poses a safety hazard, by setting up a heat dissipation mechanism composed of a fan, a dustproof net and a guide plate.

[0018] 3. This utility model solves the problem of inaccurate positioning and unreliable fixation caused by shaking during operation in traditional detachable structures by adopting a sliding fit structure of T-shaped slider and T-shaped groove, and using the engagement of rotating block and slot to lock the position of clamping block.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Example

[0022] Please refer to Figures 1 to 6 This utility model provides a wiring device for an electrochemical energy storage power station battery management system, which aims to solve the problems in the prior art where the wiring terminal 3 is complex to disassemble and assemble during maintenance, takes a long time, and has poor heat dissipation during device operation, leading to safety hazards.

[0023] like Figure 1 and Figure 2 As shown, the wiring device of the battery management system of the electrochemical energy storage power station includes a housing 1 and a mounting plate 2 fixedly connected inside the housing 1. The housing 1 is used to accommodate and protect all internal components, forming an overall frame. The mounting plate 2 serves as a mounting platform to support the wiring terminals 3, the disassembly mechanism 4, and the wire frame 6. The wiring terminals 3 are detachably mounted on the mounting plate 2 to realize the connection of wires. The disassembly mechanism 4 is set on the mounting plate 2 and is used to realize the quick fixing and release of the wiring terminals 3. Specifically, the disassembly mechanism 4 includes a limiting plate 401 fixed to one end of the mounting plate 2 and a clamping block 402 slidably connected to the other end of the mounting plate 2. The mounting plate 2 has a sliding groove 407, and a slider 403 is fixed to the bottom of the clamping block 402. The slider 403 and the sliding groove 407 form a sliding engagement, allowing the clamping block 402 to reciprocate along the length of the sliding groove 407. One end of the terminal block 3 abuts against the limiting plate 401, while the other end is clamped or released by the clamping block 402. To lock the clamping block 402, a locking block 404 is provided on the clamping block 402. The locking block 404 has a slot 406, and a rotating block 405 is rotatably connected inside it. The rotating block 405 passes through the slot 406. The rotation inside drives the locking block 404, thereby realizing the locking or unlocking function of the clamping block 402. The heat dissipation mechanism 5 is set inside the housing 1. The heat dissipation mechanism 5 is used to actively cool the inside of the device. Specifically, the heat dissipation mechanism 5 includes a fan 503 installed on one side of the housing 1. The outer cover of the fan 503 is provided with a protective cover 502. A dustproof net 504 is fixed on the inner wall of the protective cover 502 to filter the external air drawn in by the fan 503. A guide plate 501 is also fixed on the inner wall of the housing 1. The guide plate 501 is located downstream of the airflow path of the fan 503 to guide the cooling airflow. In addition, in order to organize the wires entering and exiting the device, wire brackets 6 are fixedly connected to both the front and rear ends of the mounting plate 2.

[0024] Please refer to Figure 2 , Figure 3 and Figure 5 The disassembly mechanism 4 is used to realize the quick disassembly and assembly of the terminal block 3. Two parallel sliding grooves 407 are provided on the mounting plate 2 near the end of the clamping block 402. Two sliders 403 are fixedly connected to the bottom of the clamping block 402. The cross-sectional shape of the slider 403 and the cross-sectional shape of the sliding groove 407 are T-shaped and they match each other. In the assembled state, the slider 403 slides and fits into the sliding groove 407. This T-shaped sliding fit structure ensures the high stability and anti-deflection ability of the clamping block 402 when it moves back and forth along the length direction of the sliding groove 407. At the same time, it can effectively prevent the clamping block 402 from accidentally falling off the mounting plate 2 during operation.

[0025] Please refer to Figure 4To reliably lock the position of the clamping block 402, two locking blocks 404 are provided on the clamping block 402. The two locking blocks 404 are symmetrically distributed on the top of the clamping block 402. Each locking block 404 has a slot 406, and a rotating block 405 is rotatably connected to the top of the locking block 404. The rotating block 405 can rotate around the central axis at a predetermined angle on the inner wall of the slot 406. When locking is required, the rotating block 405 is rotated counterclockwise, and a part of the rotating block 405 will be engaged in the slot 406, thereby generating a force from the locking block 404 to lock the clamping block 402 in the current position, preventing the clamping block 402 from moving along the slide groove 407. Conversely, when the rotating block 405 is rotated clockwise, the rotating block 405 disengages from the engaged position of the slot 406, unlocking the clamping block 402 and allowing the clamping block 402 to slide freely.

[0026] Please refer to Figure 1 , Figure 2 and Figure 6 The fan 503 is installed on the side wall of the housing 1 to force cold air from the outside into the housing 1. The protective cover 502 is fixed to the outside of the housing 1 by bolts or clips and completely covers the fan 503. The surface of the protective cover 502 has multiple air inlets. The dust filter 504 is fixed to the inner wall of the protective cover 502 and completely covers these air inlets. It is used to filter out dust and impurities in the air when the air is drawn in. A guide plate 501 is fixedly connected to the inner wall of the housing 1. The guide plate 501 is an inclined plate. The guide plate 501 faces the air outlet direction of the fan 503. The inclined surface can disperse and evenly guide the high-speed concentrated airflow to the terminal block 3 and the internal space of the housing 1, so as to achieve cooling of the entire device without dead angles.

[0027] In a preferred embodiment, in order to achieve a more secure fixation of the terminal block 3, the limiting plate 401 of the disassembly mechanism 4 and the mounting plate 2 are integrally formed to enhance the structural strength and positioning accuracy. The limiting plate 401 has a snap-fit ​​surface that matches the shape of the left end of the terminal block 3, so that the left end of the terminal block 3 can be accurately embedded in the limiting plate 401.

[0028] As a preferred implementation method, in order to achieve a more reliable locking effect, such as Figure 4 As shown, the clamping block 402 is provided with two locking blocks 404, and the two locking blocks 404 are symmetrically distributed on the top of the clamping block 402. When the two locking blocks 404 are locked at the same time, a more uniform and stable locking force can be provided to prevent the clamping block 402 from loosening under vibration or accidental impact.

[0029] As a preferred implementation method, in order to further improve heat dissipation efficiency, such as Figure 2As shown, there can be multiple guide plates 501, which are arranged in an array along the length of the inner wall of the outer shell 1. Multiple guide plates 501 work together to more precisely control the direction and distribution of cooling airflow, ensuring that the heat accumulation area can be adequately cooled.

[0030] As a preferred embodiment, to facilitate the organization and securing of the wires, such as... Figure 1 and Figure 5 As shown, the front and rear ends of the mounting plate 2 are fixedly connected with wire brackets 6. The wire brackets 6 have multiple through holes or comb-like structures, through which wires can pass and be isolated, avoiding tangling and mess between wires, making the wiring neater and more orderly, and also facilitating subsequent inspection and maintenance.

[0031] Working principle: During wiring, the wire first passes through the inlet at the front end of the housing 1, and then through the wire brackets 6 at both ends of the mounting plate 2. Under the guidance of the wire brackets 6, the copper core of the wire is inserted into the corresponding connection hole of the terminal block 3 and is secured. Under normal working conditions, the heat dissipation mechanism 5 is activated, and the fan 503 draws in external cold air. Before entering the housing 1, the air is filtered by the dustproof net 504 on the inner wall of the protective cover 502 to remove dust and impurities. After the clean cold air enters the housing 1, it is evenly distributed to the terminal block 3 and various corners inside the device under the guidance of the guide plate 501 on the inner wall of the housing 1, effectively carrying away the heat generated by the current, thereby avoiding the problem of the terminal block 3 being damaged due to local overheating. When it is necessary to inspect or replace the terminal block 3, first operate the disassembly mechanism 4 to disassemble it. The operator rotates the two rotating blocks 405 at the top of the clamping block 402 clockwise. The rotating blocks 405 rotate in the inner wall of the corresponding slot 406 and fit against the inner wall of the slot 406. At this time, the lock on the clamping block 402 is released. Then, pull the clamping block 402 to the right. The two sliders 403 at the bottom of the clamping block 402 will slide smoothly in the two sliding grooves 407 of the mounting plate 2. Since the sliders 403 and the sliding grooves 407 are T-shaped, the clamping block 402 will not detach from the mounting plate 2. When the clamping block 402 moves to the right a sufficient distance, the right end of the terminal block 3 loses support. At this time, the terminal block 3 can be taken out upward, so that the left end of the terminal block 3 is released from the clamping of the limiting plate 401. The whole disassembly process is quick and convenient. When installing after maintenance, first, the left end of the terminal block 3 is inserted into the inner wall of the limiting plate 401 on the left end of the mounting plate 2 for positioning. Then, the clamping block 402 on the right end of the mounting plate 2 is slid to the left until the front end of the clamping block 402 is in close contact with the right end of the terminal block 3. At this time, the rotating block 405 on the two locking blocks 404 is rotated counterclockwise. The rotating block 405 is engaged on the left end of the inner wall of the slot 406, so that the clamping block 402 is firmly locked and cannot move, thereby fixing the terminal block 3 firmly on the mounting plate 2 and completing the installation process. Through the coordinated action of the disassembly mechanism 4, the problem of excessive time spent on disassembling and installing the terminal block 3 is solved.
