The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0028] See also Figure 1 , which is a structural diagram of a distributed power access unit detection device provided by an embodiment of the present utility model. As shown in the figure, the detection device includes: a detection docking station 100 and a detection host 200; wherein,

[0029] The detection docking station 100 is connected to the detection host 200, such as Figure 2 As shown, the detection docking station 100 is used to establish a connection between the distributed power access unit 300 and the detection host 200, so that the distributed power access unit 300 can be functionally tested through the detection host 200. In particular, the detection host 200 simulates external devices connected to the distributed power access unit 300, such as upstream devices and downstream devices. The upstream devices are such as data acquisition terminals, and the downstream devices are such as charging piles and inverters. The simulated data acquisition terminal sends data acquisition instructions and control instructions to the distributed power access unit 300. The distributed power access unit 300 converts the received instructions into a protocol and forwards them to the detection host 200. The detection host 200 simulates the distributed power supply and feedbacks corresponding information (including voltage, current, active power, reactive power, and power on / off status) based on the received instructions to test the distributed power access unit 300. The detection device can be a detection platform with multiple parallel detection docking stations 100 arranged thereon. In this embodiment, the detection device has six pairs of detection docking stations 100, arranged in pairs.

[0030] See also Figures 2 to 4 , which shows the preferred structure of the distributed power access unit detection docking station provided by the embodiment of the present utility model. As shown in the figure, the distributed power access unit detection docking station 100 includes: a support panel 1, a limit installation component 2, a crimping connection component 3, a connection access cable, a test terminal 4 and a limit locking component 5; wherein,

[0031] The position limiting installation component 2 is set on the support panel 1, and is used to limit and fix the distributed power access unit 300. Specifically, the detection docking stations 100 are paired, and the two detection docking stations 100 share a support panel 1, that is, they are set side by side on a support panel 1. The position limiting installation component 2 is set on the support panel 1, and can be used to install and fix the distributed power access unit 300. Figure 2 As shown, the distributed power access unit 300 is installed on the left distributed power access unit detection docking station 100, while the right side is not installed and is an empty space.

[0032] The crimping connection assembly 3 is arranged on one side of the position limiting installation assembly 2 in a manner capable of reciprocating linear motion (such as Figure 4 Specifically, the crimping connection assembly 3 is connected to a driving member 6 for driving the crimping connection assembly 3 to perform reciprocating linear motion; wherein the driving member 6 can be an electric push rod; the support panel 1, especially the back side, is fixed with a driving fixed sheet metal 11, and the fixed end of the electric push rod is fixedly mounted on the driving fixed sheet metal 11 and can be assembled and installed by bolts. The crimping connection assembly 3 is arranged on the front side of the support panel 1 and is connected to the driving end of the electric push rod. The crimping connection assembly 3 can perform reciprocating linear motion under the driving action of the electric push rod, especially can be along Figure 4 In this embodiment, the support panel 1 may further be provided with a lifting button 61 for controlling the driving member 6 to control the movement of the crimping connector assembly 3, that is, the lifting button 61 is installed on the support panel 1 to control the lifting of the electric push rod.

[0033] One end of the connecting cable (not shown) is provided with a test terminal 4, which is arranged on the crimping connector assembly 3, and the other end is used to connect to the detection host 200. The test terminal 4 moves with the crimping connector assembly 3 toward the limit installation assembly 2, that is, Figure 3 As shown, the test terminal 4 moves upward to connect the test terminal 4 to the distributed power access unit 300, thereby connecting the distributed power access unit 300 to the detection host 2, and then performing a functional test on the distributed power access unit 300; the test terminal 4 can also move with the crimping connection assembly 3 away from the limiting installation assembly 2 to pull the test terminal 4 out of the distributed power access unit 300, thereby separating the test terminal 4 from the distributed power access unit 300, and disassembling the distributed power access unit 300. Specifically, the test terminal 4 can be fixedly installed at the top of the crimping connection assembly 3 to move up and down with the crimping connection assembly 3, and then when the crimping connection assembly 3 moves upward into place, the test terminal 4 is plugged into the corresponding interface of the distributed power access unit 300 to achieve automatic connection. Of course, the test terminal 4 can also move downward with the crimping connection assembly 3 so that the test terminal 4 can be pulled out from the corresponding interface of the distributed power access unit 300.

[0034] The limit locking assembly 5 is arranged between the limit mounting assembly 2 and the crimping connection assembly 3 in a position-adjustable manner, and is used to move toward the limit mounting assembly 2 along with the crimping connection assembly 3 until it moves to the limit stroke end and is locked on the support panel 1 to limit the distributed power access unit 300 and prevent the distributed power access unit 300 from moving back toward the limit mounting assembly 2 along with the test terminal 4 and the crimping connection assembly 3. Specifically, the limit locking assembly 5 is a limit lock structure, which is arranged between the limit installation assembly 2 and the crimping connection assembly 3. In the unlocked state, it can move toward the limit installation assembly 2 along with the crimping connection assembly 3 until it moves to the limit stroke end. That is to say, when the crimping connection assembly 3 moves upward into position, the limit locking assembly 5 can synchronously move to the limit stroke end, abutting against the bottom end of the distributed power access unit 300, and switching to the locked state at the same time, so as to limit the distributed power access unit 300. When the electric push rod is extended, it can drive the crimping connection assembly 3 to move downward. When the test terminal 4 is pulled out from the distributed power access unit 300, there will be a downward force. In order to prevent the distributed power access unit 300 from being driven downward by this force, causing the distributed power access unit 300 to fall off from the limit installation assembly 2.

[0035] Continue to see Figures 2 to 4The support panel 1 is also equipped with one or any combination of the following: a Bluetooth module 7 for Bluetooth communication with the distributed power access unit 300, an antenna module 8 connected to the Bluetooth module 7, a display module 9 for displaying test information, a backup connection module 40 for adapting to the test terminal 4, a light module 101 for indicating whether the distributed power access unit 300 is powered, and a network cable 102 for plugging into the distributed power access unit 300. Specifically, the support panel 1 may be equipped with a detection circuit board 103, which is connected to the detection host 200. Various communication lines and power lines can be connected to the detection circuit board 103 to achieve on-off control of voltage and current, as well as communication data processing. A Bluetooth mounting plate 12 is provided on the support panel 1, especially on the back side. The Bluetooth mounting plate 12 can be fixed to the support panel 1 using nuts and securely fastens the Bluetooth module 7 to the support panel 1, thereby achieving fixed installation of the Bluetooth module 7. The antenna module 8 is located in the upper right corner of the front of the support panel 1 and is connected to the Bluetooth module 7 via a cable. The display module 9 may include a display screen 91 and a display control circuit board 92, which are connected to each other. The display screen 91 and the display control circuit board 92 can be assembled and fixed to the front and back of the support panel 1 by bolts. When the device is running, the display screen 91 displays relevant detection information. The standby connection module 40 may include a communication terminal 401, a voltage terminal L 402, and a voltage terminal N 403. The communication terminal 401, the voltage terminal L 402, and the voltage terminal N 403 are installed on the support panel 1. The communication terminal 401, the voltage terminal L 402, and the voltage terminal N 403 can be connected to the external link device, i.e., the distributed power access unit 300, via a matching cable for detection. That is, the standby connection module 40 and the test terminal 4 serve as backup for each other. When the test terminal 4 is not used for automatic connection, manual connection can be performed using a cable. That is, one end of the cable is plugged into the standby connection module 40 and the other end is plugged into the distributed power access unit 300 to achieve connection between the distributed power access unit 300 and the detection host 200. When automatic connection is not used, the cable can also be directly plugged in for testing. The indicator light module 101 is mounted on the support panel 1 and displays the current status. If it is illuminated, the workstation is powered; if it is not, it is not powered. The power supply to the corresponding distributed power access unit 300 is detected by checking the power supply of the backup connection module 40 and the test terminal 4, thereby displaying the current test status of the workstation. The network cable 102 can be two sets, one end of which is plugged into the test circuit board 103, and the other end is connected to the distributed power access unit 300 during testing.

[0036] See also Figure 5 and Figure 6, which shows the preferred structure of the position limiting installation component provided by the embodiment of the present utility model. As shown in the figure, the position limiting installation component 2 includes: an upper position limiting member 21, a middle position limiting member 22 and a lower position limiting member 23 arranged in sequence from top to bottom; wherein, a guide rail groove (not shown in the figure) is provided on the back of the distributed power access unit 300; the middle position limiting member 22 is adapted to the guide rail groove and is used to be fixed to the guide rail groove to limit the distributed power access unit 300; the lower position limiting member 23 is arranged on one side of the middle position limiting member 22 in a sliding manner along the arrangement direction of the upper position limiting member 21, the middle position limiting member 22 and the lower position limiting member 23, and is used to slide back to the middle position limiting member 22 to allow the distributed power access unit 300 to be positioned. The bottom of the source access unit 300 can be installed between the middle limit piece 22 and the lower limit piece 23, and the top of the distributed power access unit 300 is placed between the middle limit piece 22 and the upper limit piece 21. The lower limit piece 23 moves toward the middle limit piece 22 to drive the distributed power access unit 300 to move, so that the guide rail groove is fixed to the middle limit piece 22, the top of the distributed power access unit 300 is fixed to the upper limit piece 21, and the bottom of the distributed power access unit 300 is clamped between the middle limit piece 22 and the lower limit piece 23, thereby completing the fixation of the distributed power access unit 300.

[0037] Specifically, the upper limit member 21 is a U-shaped plate structure with an opening facing the lower limit member 22. That is, the opening of the upper limit member 21 is arranged downward to provide sliding guidance and securement for the top of the distributed power access unit 300. During the docking process of the distributed power access unit 300, the upper limit member 21 restricts the distributed power access unit 300 from moving upward when the electric push rod is pressed upward, and also restricts the distributed power access unit 300 from moving left and right. The middle limit member 22 is a U-shaped plate structure, whose middle connection portion 221 is adapted to fit within the guide rail groove to secure the guide rail groove. The side connection portions 222 of the middle limit member 22 are used to guide the distributed power access unit 300 and restrict the left and right movement of the distributed power access unit 300 during docking. The lower side of the middle connection portion 221 is shaped like a national standard guide rail and, during testing, fits tightly with the guide rail groove at the bottom of the distributed power access unit 300, preventing the distributed power access unit 300 from moving forward or backward, that is, up or down. The lower stopper 23 is a U-shaped plate structure with an opening toward the upper stopper 21, so as to fix the bottom of the distributed power access unit 300. The upper stopper 21 and the middle stopper 22 can be fixed to the support panel 1 by bolts.

[0038] Continue to see Figure 5A guide rod 24 is provided between the lower limit member 23 and the middle limit member 22 for limiting the position adjustment of the lower limit member 23; a limit reset member 25 is further provided between the lower limit member 23 and the middle limit member 22 for applying a reset force to the lower limit member 23 so that the lower limit member 23 can move toward the middle limit member 22 and reset in a free state. Specifically, the guide rod 24 can be a half-thread bolt, which can be slidably passed through the lower limit member 23 and the middle limit member 22, and the bottom end of the guide rod 24 can be provided with a lower limit block, which can be fixed on the lower limit member 23, and the top end of the guide rod 24 can be provided with an upper limit block, which is fixed on the middle limit member 22, so as to prevent the guide rod 24 from being separated from the lower limit member 23 and the middle limit member 22. In this embodiment, a limit reset member 25 is sleeved on the guide rod 24 and positioned between the lower limit member 23 and the middle limit member 22. The two ends of the limit reset member 25 are respectively connected to the lower limit member 23 and the middle limit member 22. After the lower limit member 23 moves away from the middle limit member 22, the limit reset member 25 can apply a reset force to the lower limit member 23, allowing the lower limit member 23 to move upward and reset in a free state until the lower limit member 23 abuts the middle limit member 22, that is, the top ends of the two side support portions of the lower limit member 23 abut the bottom ends of the two side connection portions 222 of the middle limit member 22. When installing the distributed power access unit 300, the lower limit member 23 is pulled downward to place the distributed power access unit 300 into the limit installation assembly 2. The elastic force of the limit reset member 25 resets the lower limit member 23, i.e., moves it upward, and simultaneously engages the guide rail groove on the back of the distributed power access unit 300 into the bottom end of the middle connection portion 221.

[0039] See also Figure 7 , which is a structural diagram of the connection between the crimping connection assembly and the test terminal provided by the embodiment of the present utility model. As shown in the figure, the crimping connection assembly 3 may include: a driving support plate 31, a support block 32 and a terminal mounting plate 33; wherein, the driving support plate 31 is used to connect the driving member 6, the support block 32 is arranged on the driving support plate 31, and the terminal mounting plate 33 is arranged on the support block 32, and is used to support and fix the test terminal 4. Specifically, the driving support plate 31, the support block 32, the terminal mounting plate 33 and the test terminal 4 are fixed together by bolts, and the driving support plate 31 is mounted on the driving end of the electric push rod by bolts. At the same time, as Figure 3As shown, travel-fixing sheet metal 34 is installed on the left and right sides of the drive tray 31, allowing the drive tray 31 to move with the electric push rod. The interior of the support block 32 is hollow to arrange the cables of the test terminal 4. The test terminal 4 is connected to the cable leading from the detection circuit board 103 and is installed on the terminal mounting plate 33 via bolts. In this embodiment, the support panel 1 is provided with two sliding guide rails 13, wherein each sliding guide rail 13 is adapted to the two travel-fixing sheet metal 34 to guide the sliding of the travel-fixing sheet metal 34, and thus guide the sliding of the drive tray 31, that is, guide the sliding of the crimping connector assembly 3. The travel-fixing sheet metal 34, the sliding guide rail 13, and the drive-fixing sheet metal 11 serve as a fixed link, while also preventing the electric push rod from deflecting during its travel.

[0040] In this embodiment, the test terminal 4 includes a voltage terminal 41 and an RS485 terminal 42 .

[0041] Continue to see Figure 2 The limit lock assembly 5 is a limit lock structure, which includes: a guide rod 51, a limit lock body 52, a locking member (not shown in the figure) and an unlocking button 53; wherein the limit lock body 52 is along the length direction of the guide rod 51 (such as Figure 2 The guide rod 51 is slidably mounted in the vertical direction shown in the figure. A locking member is provided on the limit lock body 52 and is used to lock the limit lock body 52 to the guide rod 51 when the limit lock body 52 slides along the guide rod 51 to the limit position. The locking member is also connected to an unlocking button 53, which, when pressed, releases the lock between the limit lock body 52 and the guide rod 51. The limit lock body 52 is also connected to a lock body reset member (not shown in the figure) for pulling the limit lock body 52 back to its initial position away from the limit position when the limit lock body 52 is in a free state.

[0042] Specifically, the guide rod 51 can be vertically fixed on the support panel 1 and placed on one side of the crimping connector assembly 3 to avoid interfering with the movement of the crimping connector assembly 3. The limit lock body 52 can be arranged horizontally, that is, arranged on the guide rod 51 perpendicularly to the guide rod 51, and the limit lock body 52 can be slidably connected to the guide rod 51 along the length direction of the guide rod 51. The crimping connector assembly 3 can also be provided with a protrusion for abutting against the bottom end of the limit lock body 52, so that when the crimping connector assembly 3 moves upward, the limit lock body 52 can be pushed to move upward accordingly. When the crimping connector assembly 3 moves to the point where the test terminal 4 is plugged into the distributed power access unit 300, the limit lock body 52 moves to the top end and abuts against the bottom end of the lower limit member 23 in the fixed position, so as to limit the distributed power access unit 300 by limiting the lower limit member 23. The locking member is provided on the limit lock body 52, and when the limit lock body 52 moves to the top end and abuts against the bottom end of the lower limit member 23 in the clamping position, the limit lock body 52 and the guide rod 51 are locked, and when the crimping connection assembly 3 moves downward, the limit lock body 52 is prevented from moving downward therewith, so that when the crimping connection assembly 3 moves downward, the limit lock body 52 is locked and limits the lower limit member 23, that is, the distributed power access unit 300 is limited, so that the distributed power access unit 300 is clamped between the lower limit member 23 and the middle limit member 22 After the test terminal 4 is pulled out from the distributed power access unit 300, before disassembling the distributed power access unit 300, the limit lock body 52 can be unlocked by the unlocking button 53, thereby releasing the lock between the limit lock body 52 and the guide rod 51, and allowing the limit lock body 52 to move downward and reset under the action of gravity and the lock body reset member, thereby releasing the limit on the lower limit member 23, thereby enabling the distributed power access unit 300 to be disassembled. The unlocking button 53 can be a circular boss button.

[0043] The device has two connection modes: manual connection and automatic connection. In the manual connection mode, connection can be achieved through the spare connection module 40. In the automatic connection mode, connection is achieved by pressing the connection component 3 to drive the test terminal 4 to automatically connect.
