Abstract
Description
Technical Field
[0001] This utility model relates to the field of distributed power access technology, and more specifically, to a distributed power access device and a distributed power access unit testing system. Background Technology
[0002] With the development of energy technology, distributed generation has become an important energy supply method. This technology connects multiple distributed power sources in the power system to the main power grid to achieve energy distribution and sharing, thereby improving the reliability and stability of the power grid.
[0003] The bottom of the distributed power access unit is equipped with a fixed hole so that the pins on the distributed power access unit inspection system or the main grid can be inserted into the fixed hole to realize the connection between the distributed power access unit inspection system and the distributed power access unit. Then, the distributed power access unit can be inspected through the distributed power access unit inspection system, or the distribution and sharing of energy can be realized.
[0004] However, currently, the distributed power access unit testing system and the pin headers on the distributed power access unit are of various types. The distributed power access unit cannot adapt to different types of pin headers, making the connection cumbersome and requiring one-to-one adaptation. Summary of the Invention
[0005] In view of this, the present invention proposes a distributed power access device and a distributed power access unit testing system, aiming to solve the problem that the existing distributed power access units have fixed sockets that cannot be adapted to different types of pin headers.
[0006] On one hand, this utility model proposes a distributed power access device. The bottom of the distributed power access device is provided with a socket. At least three radial adjustment slots are opened on the outside of the socket. The radial adjustment slots are arranged at intervals along the circumference of the socket. Each radial adjustment slot is provided with a support rod that penetrates and partially extends into the socket. The support rods are distributed radially along the socket. The end of each support rod placed in the socket is provided with an arc-shaped connecting plate. Furthermore, an elastic reset member is provided between the other end of the support rod and the radial adjustment slot. This is used to push the multiple arc-shaped connecting plates to move in opposite directions to compress the corresponding elastic reset member when the pins are gradually inserted between them. This causes the multiple arc-shaped connecting plates to press around the pins, thereby achieving clamping of the pins and electrical connection with them.
[0007] Furthermore, in the aforementioned distributed power access device, the elastic reset element is a spring.
[0008] Furthermore, in the aforementioned distributed power access device, there are four support rods and four radial adjustment slots, all of which are evenly arranged circumferentially along the insertion hole.
[0009] Furthermore, in the aforementioned distributed power access device, when each of the elastic reset members is in a free state, the ends of the multiple support rods connected to the arc-shaped connecting plates are located on a circle.
[0010] On the other hand, this utility model also proposes a distributed power access unit inspection system, which includes: a support frame; a parallel detection unit disposed on the top front of the support frame for inspecting distributed power access devices; an electrical cabinet disposed inside the support frame and located on the bottom front side; and an inspection platform disposed above the electrical cabinet.
[0011] Furthermore, in the aforementioned distributed power access unit inspection system, the parallel inspection unit includes: a plurality of parallel mounting bases for supporting and inspecting the distributed power access device; and a plurality of displays corresponding one-to-one with the mounting bases, positioned above the corresponding mounting bases for displaying the inspection information of the distributed power access device supported by the corresponding mounting bases.
[0012] Furthermore, in the aforementioned distributed power access unit inspection system, the fixing base includes: a base body; a snap-fit block disposed on the front of the base body and mounted on the base body for pressing and securing the distributed power access device to achieve the fixation of the distributed power access device; and a wiring terminal disposed on the lower side of the snap-fit block and disposed on the base body in a manner capable of reciprocating linear motion. The wiring terminal is provided with pins for reciprocating linear motion with the wiring terminal to be inserted into the corresponding socket of the distributed power access device, and is clamped and connected by an arc-shaped connecting plate.
[0013] Furthermore, in the aforementioned distributed power access unit testing system, the wiring terminal is connected to a telescopic drive component, which is used to drive the wiring terminal to perform reciprocating linear motion.
[0014] Furthermore, in the aforementioned distributed power supply access unit inspection system, the telescopic drive component is an electric actuator.
[0015] Furthermore, in the aforementioned distributed power access unit testing system, the bottom of the support frame is provided with an insulating base, and the side of the support frame is provided with heat dissipation holes, each of which is equipped with a filter.
[0016] The distributed power access device and distributed power access unit inspection system provided by this utility model, when the pin header on the distributed power access unit inspection system is gradually inserted between multiple arc-shaped connecting plates, the pin header simultaneously squeezes the multiple arc-shaped connecting plates, causing the multiple arc-shaped connecting plates to simultaneously drive multiple support rods to move into the interior of multiple radial adjustment slots. In turn, the multiple support rods simultaneously squeeze multiple elastic reset members, and the multiple elastic reset members simultaneously contract into the interior of multiple radial adjustment slots. During the movement, the elastic reset members will not wobble from side to side due to their high rigidity, making the pin header insertion more secure and adaptable to pin headers of different sizes. This solves the problem that the fixed sockets on existing distributed power access units cannot adapt to different types of pin headers, thus expanding the adaptability of the distributed power access device.

Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the disclosure to those skilled in the art. It should be noted that, unless otherwise specified, embodiments and features of the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0025] Device Example:
[0026] See Figures 1 to 3 The figure illustrates a preferred structure of the distributed power access device provided in this embodiment of the present invention. As shown, the distributed power access device 100 has a socket 101 at its bottom, and at least three radial adjustment slots 102 are provided on the outside of the socket 101. The radial adjustment slots 102 are arranged at intervals along the circumference of the socket 101. Each radial adjustment slot 102 has a support rod 103 that penetrates through and partially extends into the socket 101. The support rods 103 are radially distributed along the socket 102. The end of each support rod 103 placed in the socket 101 has an arc-shaped connecting plate 104. Furthermore, a spring is provided between the other end of the support rod 103 and the radial adjustment slot 102. The elastic reset member 105 is used to push the multiple arc-shaped connecting plates 104 to move in opposite directions to compress the corresponding elastic reset member 105 when the pins 2214 on the distributed power access unit inspection system 200 are gradually inserted between multiple arc-shaped connecting plates 104. This causes the multiple arc-shaped connecting plates 104 to be squeezed around the pins 2214, thereby clamping the pins 2214 and establishing an electrical connection between the distributed power access device 1 and the pins 2214. This allows the distributed power access device 100 to be inspected by the distributed power access unit inspection system 200.
[0027] Specifically, the radial adjustment groove 102, support rod 103, arc-shaped connecting plate 104, and elastic reset member 105 are all one-to-one corresponding. When a pin header is inserted between multiple arc-shaped connecting plates 104, the pin header presses against the arc-shaped connecting plate 104, causing the arc-shaped connecting plates 104 to move in opposite directions. This, in turn, drives the support rod 103 to move radially outward along the insertion hole 101 within the corresponding radial adjustment groove 102, compressing the corresponding elastic reset member 105. This causes the elastic reset member 105 to apply an inward reset force, thereby achieving the clamping of pin headers of different sizes. In this embodiment, there are four radial adjustment grooves 102, support rods 103, arc-shaped connecting plates 104, and elastic reset members 105, all evenly arranged along the circumference of the insertion hole 101, i.e., the included angle between two adjacent support rods 103 is 90°. To further ensure the stability of the pin header clamping, preferably, multiple support rods 103 are connected to the ends of the arc-shaped connecting plates 105 (e.g., ...). Figure 2 The end shown, placed inside the socket 101, is located on a circle. The elastic reset member 105 can be a spring or other elastic reset member; no limitation is made in this embodiment.
[0028] In this embodiment, the insertion hole 101 is larger than the outer diameter of most of the pin headers. The arrangement of the multiple arc-shaped connecting plates 104 is adjusted according to the size of the pin headers. When the diameter of the pin header 2214 is large, it is inserted into the insertion hole 101. At the same time, the pin header 2214 simultaneously presses against the four arc-shaped connecting plates 104, causing the four arc-shaped connecting plates 104 to simultaneously drive the four support rods 103 to move into the four radial adjustment grooves 102. Then, the four support rods 103 simultaneously press against the four elastic reset members 105, and the four elastic reset members 105 simultaneously contract into the four radial adjustment grooves 102, thus achieving elastic reset. During movement, component 105 does not wobble from side to side due to its high rigidity, making the pin header 2214 more securely inserted. When the size of the pin header 2214 is small, the elastic reset component 105 will spring back to fix the smaller diameter pin header 2214, thereby allowing the larger pin header to be inserted into the socket 101. The positional relationship of the multiple arc-shaped connecting plates 104 can be adjusted according to the size of the pin header 2214, thus making it suitable for crimping more pin headers of different sizes. This realizes the adaptive insertion application of the pin header 2214, and it can also be applied to different models of distributed power access units.
[0029] It should be added that, since the sockets 101 are arranged in a row, different sizes and numbers of pin headers 2214 can be plugged in at the same time during the plugging process. This achieves the purpose of plugging in multiple pin headers 2214 at the same time, further improving the practicality and convenience of the distributed power access unit testing device and bringing great convenience to the operators.
[0030] In summary, the distributed power access device provided in this embodiment, when the pin header 2214 on the distributed power access unit inspection system 200 is gradually inserted between multiple arc-shaped connecting plates 104, simultaneously presses the multiple arc-shaped connecting plates 104, causing the multiple arc-shaped connecting plates 104 to simultaneously drive multiple support rods 103 to move into the interior of multiple radial adjustment slots 102. Furthermore, the multiple support rods 103 simultaneously press multiple elastic reset members 105, causing the multiple elastic reset members 105 to simultaneously contract into the interior of the multiple radial adjustment slots 102. Due to their high rigidity, the elastic reset members 105 do not wobble left or right during movement, making the pin header 2214 more firmly inserted and adaptable to pin headers of different sizes. This solves the problem that existing distributed power access units with fixed sockets cannot adapt to different types of pin headers, thus expanding the adaptability of this distributed power access device.
[0031] System Implementation Example:
[0032] See Figure 4 This is a schematic diagram of the structure of the distributed power access unit inspection system provided in this embodiment of the present invention. As shown in the figure, the distributed power access unit inspection system 200 includes: a support frame 210, a parallel testing unit 220, an electrical cabinet 230, and an inspection table 240; wherein, the parallel testing unit 220 is disposed on the top front of the support frame 210 and is used to inspect the aforementioned distributed power access device 100; the electrical cabinet 230 is disposed inside the support frame 210, located at the bottom front side, and is used to house and protect various electrical components; the inspection table 240 is disposed above the electrical cabinet 230 and is used to provide a platform for actual inspection operations.
[0033] Specifically, the support frame 210 serves as the outer frame, supporting, protecting, and fixing the distributed power access device 100. In this embodiment, the support frame 210 surrounds the entire inspection system 200, reducing physical impact and damage to the inspection device. When the device is exposed to harsh environments, the support frame 210 effectively mitigates the impact of external forces on the inspection device and effectively protects the safety of the internal components. The support frame 210 is made of metal, which is generally more robust and can withstand greater impacts and loads. A power switch 211 is located on the right side of the support frame 210, used to control the power switch status of the inspection system. The power switch 211 controls the power supply to the entire device and has three switch buttons. The inspection platform 240 is installed below and at the front of the support frame 210, serving as a platform for actual inspection operations, supporting and operating the power access unit, or as a workbench. The platform height can be 90cm, or can be determined according to actual conditions; this embodiment does not impose any limitations on it. The parallel detection unit 220 is installed above the support frame 210, used to verify and test the power quality of the distributed power access device. Electrical cabinet 230 is installed below support frame 210 to house and protect various electrical components. It provides safe electrical isolation and environmental protection for the enclosed enclosure housing electrical components and connecting circuits, ensuring the normal operation of power access devices and other electrical equipment. The system also includes a main control unit inside support frame 210 for local control functions and data processing of the distributed power access device, sending control commands and receiving feedback signals. A host computer is installed on support frame 210, located outside, to remotely control the distributed power access device 100, sending control commands, verifying the normality of control functions, sending control commands to the main control unit (such as start, stop, and parameter settings), and receiving verification data and results from the main control unit. A transmission unit is installed inside support frame 210 for data transmission between the main control unit and the host computer, using wireless data communication methods, including 5G and Wi-Fi.
[0034] In this embodiment, the bottom of the support frame 210 is provided with an insulating base 212, and the sides of the support frame 210 are provided with heat dissipation holes 213, each of which is equipped with a filter 214. Specifically, the insulating base 212 provides electrical safety protection, preventing short circuits or electric shock accidents caused by current passing through the contact points between the testing device and the ground or other metal parts. Simultaneously, the insulating base 212 also provides stable support for internal electronic components. The insulating base 212 is made of rubber, which has excellent electrical insulation properties, effectively preventing current from flowing from one part of the equipment to another. The heat dissipation holes 213 are evenly distributed in a circular pattern on the left and right sides of the protective frame 110. This layout helps promote air circulation, allowing external air to better enter the testing device, thereby reducing the risk of malfunction due to overheating. To further ensure the testing... During normal operation of the device, filter 214 is embedded in heat dissipation hole 213. The function of filter 214 is to prevent dust and debris from entering the heat dissipation device. For example, if dust is deposited on the chip surface, it will hinder heat conduction and air circulation, leading to a decrease or failure of heat dissipation capacity. Filter 214 effectively blocks dust particles, ensuring the unobstructed flow of heat dissipation hole 213, thereby ensuring the smooth operation of the inspection process. Filter 214 is composed of metal mesh, fiber material and activated carbon. The metal mesh is used for preliminary filtration of large particles and has good air permeability and mechanical strength. The fiber material can effectively capture fine dust and particles and has excellent filtration effect. Activated carbon is used to adsorb harmful gases and odors.
[0035] See also Figure 4 The parallel detection unit 220 includes several mounting bases 221 and several displays 222. The mounting bases 221 are arranged in parallel to support and test the distributed power access device 100. Each display 222 corresponds to one of the mounting bases 221 and is positioned above the corresponding mounting base 221 to display the test information of the distributed power access device 100 supported by that mounting base 221. Specifically, the parallel detection unit 220 includes 12 mounting bases 221 and 12 displays 222, arranged in two rows, with 6 mounting bases 221 and 6 displays 222 in each row. The mounting bases 221 are mounted on the support frame 210, and the displays 222 are mounted above the mounting bases 221. The displays 222 are used to display the operating status and test results of the distributed power access device, providing real-time monitoring and feedback. The displays 222 use LCD or LED screens, featuring high definition, high contrast, and low energy consumption.
[0036] See also Figure 1The fixing base 221 includes: a base body 2211, a snap-fit block 2212, and a terminal block 2213; wherein, the snap-fit block 2212 is disposed on the front side of the base body 2211 and mounted on the base body 2211, and is used to press and fix the distributed power access device 100 to achieve the fixation of the distributed power access device 100; the terminal block 2223 is disposed on the lower side of the snap-fit block 2212 and is disposed on the base body 2211 in a manner that allows for reciprocating linear motion, and the terminal block 2213 is provided with pins 2214, which are used to reciprocate linearly with the terminal block 2213 to be inserted into the corresponding socket 101 of the distributed power access device 100, and are clamped and connected by the arc-shaped connecting plate 104.
[0037] Specifically, the snap-fit block 2212 can be placed on the front of the base body 2211 and can be installed on the base body 2211 by bolts or other means to press and secure the distributed power access device 100, thereby fixing the distributed power access device 100 and enabling testing of the distributed power access device 100. The snap-fit block 2212 is located on the front of the base body 2211 and installed on the upper part of the base body 2211, and the pin header 2214 is located above the terminal block 2223 (relative to the terminal block 2223). Figure 1 (As shown in the diagram), the pin header 2214 moves upward with the terminal 2223, that is, it moves towards the snap-fit block 2212 located above the terminal 2223, thereby pressing it onto the distributed power access device 100, that is, inserting it into the corresponding socket 101 of the distributed power access device 100, thereby detecting the distributed power access device 100. The pin header 2214 is typically arranged in an array on the terminal 2213, divided into two arrays, one array with two pin headers and the other array with four pin headers, for example, as... Figure 5As shown, the terminal block 2213 includes two pin header bases. One pin header base has four pins 2214, and the other pin header base has two pins 2214. The pins are made of conductive materials, such as copper alloy, which are wear-resistant and corrosion-resistant, ensuring the stability and reliability of the electrical connection. Each pin 2214 is connected to a wire 2215, corresponding to six pins 2214 respectively. The outer layer of the wire 2215 is made of insulating material to prevent electric shock and short circuit. The terminal block 2213 is also provided with fixing holes 2216 for fixing the terminal block 2213 to the testing device. The fixing holes 2216 are located behind the terminal block 2213, and there are two fixing holes 2216. The terminal block 2213 is fixed to other components by bolts, nuts or other fasteners to ensure its stability and reliability. During installation, care should be taken not to damage the wires and pins. Terminal 2213 is connected to a telescopic drive (not shown in the figure), which drives terminal 2213 to reciprocate linearly, thereby driving terminal 2213 to move towards or away from the locking block 2212, and thus allowing pin 2214 to be inserted into or pulled out of the socket 101 of the drinking vessel. In this embodiment, the telescopic drive can be disposed on the back of the base body 2211. The base body 2211 has a mounting through hole 2216, and a connecting plate passing through the mounting through hole 2216 is provided at the mounting through hole 2216. Its two ends are respectively connected to terminal 2213 and telescopic drive, and are used to drive terminal 2213 to reciprocate linearly under the driving action of telescopic drive. In this embodiment, the telescopic drive can be an electric actuator or other drive components, and no limitation is made on it in this embodiment. The terminal block 2213 is provided with a protective housing to protect the internal electrical connection parts from the influence of the external environment, such as dust, moisture and mechanical impact. The design of the protective housing should take into account easy installation and disassembly, while ensuring sufficient strength to protect the internal electrical connection.
[0038] In this embodiment, the mounting base 221 is also provided with an adjustment button 2217 to adjust the test parameters. The test parameters include at least voltage, current, frequency and temperature. By rotating the adjustment knob, these parameters can be precisely set and adjusted to meet different testing requirements of the distributed power access unit.
[0039] In a specific embodiment, the environment in which the system operates is: relative humidity of 30% to 60%, temperature of +15℃ to +35℃, and atmospheric pressure of 86kPa to 108kPa; the power supply conditions of the testing device are: frequency of 50Hz, allowable deviation of -2% to +1%, voltage of 12V, and allowable deviation of ±5%.
[0040] In summary, the distributed power access unit inspection system provided in this embodiment inspects the distributed power access device through parallel testing units, is supported by an electrical cabinet, and is constructed using an inspection table.
