[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides: a distributed power supply that is easy to connect in parallel, such as... Figures 1-4 As shown, the system includes a power supply body 1, and a connection component 2 for connecting two power supplies is provided on the side wall of the power supply body 1. The power supply body 1 is the core of the distributed power supply and also serves as the mounting carrier for the connection component 2. The connection component 2 is located on the side wall of the power supply body 1 and is used to enable rapid parallel connection of two power supply bodies 1.

[0025] The connecting component 2 includes several sets of limiting blocks 21 installed on one side of the power supply body 1, and a fixing block 22 installed on the other side of the power supply body 1. The side wall of the fixing block 22 is provided with several sets of limiting grooves 23 that are adapted to the position and shape of the limiting blocks 21. The inner side wall of each set of limiting grooves 23 is provided with several sets of positioning grooves 24. Several sets of positioning blocks 25 that cooperate with the positioning grooves 24 are movably installed on the side wall of each set of limiting blocks 21. When the limiting block 21 is inserted into the limiting groove 23, the positioning block 25 will be engaged in the corresponding positioning groove 24. A limiting block 21 is installed on one side of the power supply body 1, and a fixing block 22 is installed on the other side of the same power supply body 1. The limiting groove 23 on the fixing block 22 is precisely matched in position and shape with the limiting block 21 of the other power supply body 1, providing physical guidance for the alignment of the two power supplies. When the limiting block 21 is inserted into the limiting groove 23, the positioning block 25 on the limiting block 21 will engage with the positioning groove 24 on the inner wall of the limiting groove 23, forming a mechanical lock. When two power supplies need to be paralleled, the limiting block 21 of one power supply body 1 is aligned with the limiting groove 23 of the other power supply body 1 and inserted. During this process, the positioning block 25 and the positioning groove 24 automatically engage, and the mechanical fixing of the two power supply bodies 1 can be completed without bolts and special tools. This solves the problem of cumbersome installation of traditional bolt connections, significantly simplifies the paralleling process, improves deployment and maintenance efficiency, enhances equipment flexibility and availability, and adapts to the rapid paralleling needs of different scenarios.

[0026] Preferably, each set of limiting blocks 21 has several sets of mounting slots 26 on its side wall, and each set of positioning blocks 25 is movably installed inside the corresponding mounting slot 26. The mounting slots 26 are formed on the side wall of each set of limiting blocks 21 to provide dedicated installation space and movement guidance for the positioning blocks 25, ensuring that the positioning blocks 25 can only move within a preset trajectory and preventing the positioning blocks 25 from deviating and causing engagement failure. When the limiting block 21 is inserted into the limiting slot 23, the positioning block 25 is squeezed by the inner wall of the limiting slot 23 and will retract into the slot along the mounting slot 26. When the positioning block 25 moves to the position of the positioning slot 24, the squeezing force disappears, and the positioning block 25 pops out along the mounting slot 26 and engages with the positioning slot 24.

[0027] Furthermore, each set of mounting slots 26 is equipped with a spring 27 inside, and the two ends of each spring 27 elastically abut against the inner wall of the corresponding mounting slot 26 and the end of the positioning block 25, respectively. The elastic force of the spring 27 ensures that the positioning block 25 always has the tendency to pop outward, ensuring the stable engagement of the positioning block 25 and the positioning slot 24, while providing power for the retraction and reset of the positioning block 25. In the initial state, the spring 27 is in a naturally extended or slightly compressed state, applying an outward pushing force to the positioning block 25, causing the positioning block 25 to partially extend out of the mounting groove 26; when the limiting block 21 is inserted into the limiting groove 23, the positioning block 25 is squeezed into the mounting groove 26, and the spring 27 is compressed to generate elastic potential energy; when the positioning block 25 is aligned with the positioning groove 24, the compressed spring 27 releases its elastic potential energy, pushing the positioning block 25 to quickly pop out and lock into the positioning groove 24, realizing the locking of the two power supplies; when disassembling, the external force pulls the power supply body 1 to compress the spring 27 and retract the positioning block 25, and after it is separated from the positioning groove 24, the spring 27 pushes the positioning block 25 back to the initial extended state.

[0028] Furthermore, the snap-fit ​​end of each positioning block 25 is designed as a hemispherical structure, and the cavity shape of each positioning groove 24 is adapted to the hemispherical snap-fit ​​end of the positioning block 25. The core function of designing the snap-fit ​​end of the positioning block 25 as hemispherical is to reduce frictional resistance during the snap-fit ​​and disengagement process; the cavity shape of the positioning groove 24 is adapted to the hemispherical snap-fit ​​end, which can realize the precise embedding of the positioning block 25, while providing a smooth force surface for the disengagement of the positioning block 25.

[0029] It is worth noting that each set of limiting slots 23 has an integrally formed guide slope 28 at the edge of its insertion port. During the insertion process, the limiting block 21 can slide precisely into the corresponding limiting slot 23 through the guide slope 28. The guide slope 28 is integrally formed on the edge of the insertion port of each set of limiting slots 23, and its tilt angle is designed to correct slight positional deviations when the two sets of power supply bodies 1 are connected, reducing the difficulty of parallel operation. When the operator connects the two sets of power supply bodies 1, if there is a slight misalignment between the limiting block 21 and the limiting slot 23, the insertion end of the limiting block 21 will first contact the guide slope 28; as the two sets of power supply bodies 1 continue to approach, the guide slope 28 will generate a guiding force on the limiting block 21 along the slope direction, guiding the limiting block 21 to the correct entrance of the limiting slot 23, eliminating the need for repeated position adjustments and greatly improving the efficiency and accuracy of parallel alignment.

[0030] Specifically, each power supply unit 1 has a base 3 installed at its bottom, and several fans 4 are symmetrically embedded in the side wall of each base 3. The base 3 is used to support the power supply unit 1, improve the stability of the power supply placement, and provide installation space for the fans 4; the fans 4 are symmetrically embedded in the side wall of the base 3, responsible for dissipating the heat generated by the power supply during operation, preventing overheating from affecting equipment performance or causing malfunctions.

[0031] Fan 4 can be an axial flow fan with an air volume of 180-220 CFM, a static pressure of 2.5-3.5 mmH2O, a speed of 2200-2500 RPM, and an operating voltage of DC24V. The 180-220 CFM air volume can quickly remove the heat generated by the internal electronic components, and the 2.5-3.5 mmH2O static pressure can overcome the airflow resistance between the base 3 and the power supply body 1, ensuring that the heat dissipation airflow evenly covers the inside of the equipment and avoids local overheating; the DC24V voltage conforms to the common auxiliary power supply specifications of distributed power supplies, requiring no additional power adapter, and the 2200-2500 RPM speed balances heat dissipation efficiency and operational stability.

[0032] More specifically, each power supply unit 1 is equipped with a converter 5 on its upper part, and each converter 5 has a parallel interface at its output end. The parallel interfaces of two adjacent power supply units 1 are detachably connected via copper busbars. The converter 5 is used to convert the electrical energy generated by the power supply unit 1 into electrical energy that meets the requirements for parallel operation, and to adjust parameters such as voltage and frequency to ensure the consistency of electrical energy output from multiple power supplies. The parallel interface is located at the output end of the converter 5 and is the interface for power transmission, used to connect external conductive components. The copper busbar, as a detachable connection component, is used to connect the parallel interfaces of two adjacent power supply units 1 to realize the conduction and parallel operation of electrical energy.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
