Description

Technical Field

[0001] This invention belongs to the technical field of substation energy storage devices, and specifically relates to a substation energy storage device. Background Technology

[0002] Substation energy storage devices in related technologies typically consist of a cabinet with charging / discharging ports, a charging / discharging cable with a charging / discharging plug, and a standard plug-in connection between the plug and the port. This connection lacks effective physical constraints. In actual operation, substation energy storage devices often need to operate continuously for hours to tens of hours. During this time, the cable is prone to shaking, loosening, or even completely detaching from the charging / discharging port due to its own weight, accidental kicking, or other external forces. This abnormally interrupts the charging / discharging process, requiring maintenance personnel to rewire and disrupting normal operations.

[0003] Therefore, the charging and discharging cables of substation energy storage devices in related technologies are prone to detaching from the charging and discharging ports. Summary of the Invention

[0004] The present invention aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, embodiments of the present invention propose a substation energy storage device.

[0006] The substation energy storage device of this invention includes:

[0007] A cabinet is provided with a charging / discharging interface, and a limiting component is provided on the cabinet adjacent to the charging / discharging interface. The limiting component includes: A support plate is connected to the cabinet. The support plate is provided with a cable passing assembly, which includes a clamping seat and a clamping member. The clamping seat is provided with a cable placement groove, and at least part of the clamping member is movably fitted in the cable placement groove. The clamping seat and the clamping member define a clamping channel through which the cable passes. A clamping assembly includes a rotating connecting part, a clamping plate, and a locking plate. The clamping plate is movable between a clamping position that abuts against the clamping member and a releasing position that is disengaged from the clamping member. The locking plate is movable between a locking position that is connected to the support plate and an unlocking position that is disengaged from the support plate. When the pressing plate is in the pressing position, the locking plate is in the locking position; when the pressing plate is in the releasing position, the locking plate is in the releasing position; both the pressing plate and the locking plate are connected to the cabinet through a rotating connection, so that the pressing plate can move between the pressing position and the releasing position, and the locking plate can move between the locking position and the unlocking position.

[0008] It is understandable that when the cable charging / discharging plug is inserted into the charging / discharging interface, the clamping plate can be moved to the clamping position, and the locking plate can be moved to the locking position. This allows the clamping component to lock while clamping the cable, preventing the clamping plate of the clamping component from moving to the release position during the clamping process. This ensures that the cable is continuously clamped and prevents the cable charging / discharging plug from falling off the charging / discharging interface. Meanwhile, when it is necessary to unplug the cable's charging / discharging plug from the charging / discharging interface, the clamping plate can be moved to the release position, and the locking plate can be moved to the unlock position, so that the clamping plate can stop clamping the cable, and the cable's charging / discharging plug can be unplugged from the charging / discharging interface.

[0021] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0022] In order to solve the problem that the charging and discharging cables of the substation energy storage device 100 in the related technology are prone to falling off from the charging and discharging port, the present invention provides a substation energy storage device 100.

[0023] like Figures 1-8As shown, the substation energy storage device 100 of this embodiment includes a cabinet 1. The cabinet 1 has a charging / discharging interface 101, and a limiting component 2 is provided on the cabinet 1 adjacent to the charging / discharging interface 101. The limiting component 2 includes a support plate 3 and a clamping component 5. The support plate 3 is connected to the cabinet 1 and has a cable passage component 4. The cable passage component 4 includes a clamping seat 401 and a clamping member 402. The clamping seat 401 has a cable placement groove 403, and at least a portion of the clamping member 402 is movably fitted within the cable placement groove 403. The clamping seat 401 and the clamping member 402 define a clamping channel 405 through which the cable passes. The clamping component 5 includes a rotating connection part 501, a clamping plate 502, and a locking plate 503. 502 can move between a pressing position abutting against the pressing member 402 and a releasing position disengaging from the pressing member 402; locking plate 503 can move between a locking position connected to the support plate 3 and an unlocking position disengaging from the support plate 3; when pressing plate 502 is in the pressing position, locking plate 503 is in the locking position; when pressing plate 502 is in the releasing position, locking plate 503 is in the unlocking position; both pressing plate 502 and locking plate 503 are connected to cabinet 1 via rotating connection part 501, so that pressing plate 502 can move between the pressing position and the releasing position, and locking plate 503 can move between the locking position and the unlocking position.

[0024] It is understandable that when the cable charging / discharging plug is inserted into the charging / discharging interface 101, the clamping plate 502 can be moved to the clamping position, and the locking plate 503 can be moved to the locking position, so that the clamping component 5 can lock while clamping the cable, preventing the clamping plate 502 of the clamping component 5 from moving to the release position during the clamping process of the cable, thereby continuously clamping the cable and preventing the cable charging / discharging plug from falling off from the charging / discharging interface 101; Meanwhile, when it is necessary to pull the cable charging / discharging plug out of the charging / discharging interface 101, the clamping plate 502 can be moved to the release position, and the locking plate 503 can be moved to the unlock position, so that the clamping plate 502 can stop clamping the cable, and the cable charging / discharging plug can be pulled out of the charging / discharging interface 101.

[0025] Therefore, the substation energy storage device 100 of the present invention can avoid the problem of charging and discharging cables falling off from the charging and discharging port.

[0026] In some embodiments, such as Figure 2 and Figure 3As shown, the rotating connection part 501 includes a rotating shaft seat 5011 and a rotating arm 5012. One end of the rotating arm 5012 is rotatably connected to the rotating shaft seat 5011, and the other end of the rotating arm 5012 is connected to the pressure plate 502, which extends horizontally. The other end of the rotating arm 5012 is connected to the locking plate 503, which extends vertically. In other words, both the pressure plate 502 and the locking plate 503 are connected to the other end of the rotating arm 5012, and the rotating arm 5012 can rotate the pressure plate 502 and the locking plate 503 synchronously.

[0027] Meanwhile, the support plate 3 has a mounting cavity 301, and the upper surface of the support plate 3 is provided with a first locking port 312 that communicates with the mounting cavity 301. The locking plate 503 is adapted to extend through the first locking port 312 into the mounting cavity 301. The left side of the support plate 3 is provided with a second locking port 313 that communicates with the mounting cavity 301. A lock head 315 is slidably provided in the second locking port 313. The locking plate 503 is provided with a locking groove 5031, and one end of the lock head 315 is adapted to fit into the locking groove 5031.

[0028] The locking plate 503 can be inserted into the mounting cavity 301 through the first locking port 312, and at the same time, one end of the locking head 315 is inserted into the locking groove 5031 of the locking plate 503 to achieve locking. At this time, the locking plate 503 is in the locked position. At the same time, one end of the locking head 315 is pulled out from the locking groove 5031, and the locking plate 503 can be pulled out through the first locking port 312. At this time, the locking plate 503 is in the unlocked position.

[0029] It is understandable that when the locking plate 503 is in the locked position, the pressing plate 502 is in the pressing position, that is, the locking plate 503 can lock the pressing plate 502; when the locking plate 503 is in the unlocked position, the pressing plate 502 is in the released position, that is, the locking plate 503 stops locking the pressing plate 502.

[0030] In some embodiments, the clamping member 402 has a first clamping block 4021 and a second clamping block 4022 on its end face adjacent to the clamping seat 401, and the bottom surface of the cable placement groove 403 has a clamping groove 4031 corresponding to the first clamping block 4021. The thickness of the first clamping block 4021 is greater than the thickness of the second clamping block 4022.

[0031] The first pressure block 4021 and the second pressure block 4022 can be rubber blocks. When the pressure plate 502 is in the pressing position, the first pressure block 4021 and the second pressure block 4022 can press the cable in the cable placement groove 403. At the same time, the thickness of the first pressure block 4021 is set to be greater than the thickness of the second pressure block 4022. Meanwhile, the bottom surface of the cable placement groove 403 is provided with a pressing groove 4031 corresponding to the first pressure block. The first pressure block 4021 and the pressing groove 4031 cooperate to further press the cable and prevent the cable charging and discharging plug from coming out of the charging and discharging port.

[0032] In some embodiments, the support plate 3 is provided with a guide plate 6, the guide plate 6 having a guide cavity 601, and a guide post 602 provided in the guide cavity 601. The guide post 602 extends in the vertical direction, one end of the guide post 602 is connected to the upper wall of the guide cavity 601, and the other end of the guide post 602 is connected to the lower wall of the guide cavity 601. A guide slide seat 603 is slidably disposed on the guide column 602. A guide opening 604 is provided on the side of the guide plate 6 adjacent to the cable passing assembly 4. The guide slide seat 603 passes through the guide opening 604 and is connected to the clamping member 402. A first spring 605 is sleeved on the guide post 602. One end of the first spring 605 is connected to the guide sliding seat 603, and the other end of the first spring 605 is connected to the lower wall of the guide cavity 601.

[0033] By setting a guide post 602 and connecting the guide sliding seat 603 slidably set on the guide post 602 to the clamping member 402, the clamping plate 502 is made more stable during movement. At the same time, a first spring 605 is set so that when the lock head 315 is pulled out from the locking groove 5031, it can drive the clamping plate 502 and the locking plate 503 to move upward.

[0034] In some embodiments, a pull plate 303 is provided on the left side of the support plate 3, and a pull rod 302 is provided in the mounting cavity 301. One end of the pull rod 302 is connected to the right wall of the mounting cavity 301 through a first tension spring 314, and the other end of the pull rod 302 passes through the support plate 3 and is connected to the pull plate 303; the other end of the lock head 315 is connected to the pull plate 303; and a pull ring 304 is provided on the left side of the pull plate 303.

[0035] By connecting the pull plate 303 to the other end of the lock head 315, the lock head 315 can be moved by the pull plate 303. At the same time, the pull rod 302 and the first tension spring 314 cooperate to enable the pull plate 303 to self-reset to the left when it is pulled to the right. Meanwhile, a pull ring 304 is provided on the left side of the pull plate 303 to facilitate the operator to pull the pull plate 303.

[0036] In some embodiments, such as Figures 4-7As shown, a drive plate 305 is provided in the mounting cavity 301. The drive plate 305 extends in the left and right direction. One end of the drive plate 305 is provided with a drive wheel 306. The other end of the drive plate 305 passes through the support plate 3 and is connected to the pull plate 303. The clamping seat 401 is slidable relative to the support plate 3, and the upper surface of the support plate 3 is provided with a sliding opening 307 corresponding to the clamping seat 401, which communicates with the mounting cavity 301. The mounting cavity 301 is also provided with a sliding member 308. The sliding member 308 is connected to the pressing seat 401 through the connecting block 311 provided in the sliding port 307. The sliding member 308 has a transmission inclined surface 3081. The transmission inclined surface 3081 extends in the left front direction. The drive wheel 306 abuts against the transmission inclined surface 3081. A second spring 309 is provided between the sliding member 308 and the front wall of the mounting cavity 301. One end of the second spring 309 is connected to the sliding member 308, and the other end of the second spring 309 is connected to the front wall of the mounting cavity 301.

[0037] It is understandable that the sliding member 308 is connected to the pressing seat 401 through the connecting block 311 provided in the sliding port 307. That is to say, the sliding member 308 can drive the pressing seat 401 to move in the front and back direction. When the pull plate 303 is pulled to the right, it drives the drive wheel 306 to move to the right. The drive wheel 306 drives the sliding member 308 to move forward through the transmission inclined surface 3081, which in turn drives the pressing seat 401 to move forward. Understandably, before the lock head 315 is pulled out of the locking groove 5031, the clamping member 402 is still clamping the cable under the action of the clamping plate 502. At this time, the drive wheel 306 is driven to move to the right. The drive wheel 306 drives the sliding member 308 to move forward through the transmission inclined surface 3081, which in turn drives the clamping seat 401 to move forward, which in turn drives the cable to move forward, thereby pulling the cable charging and discharging plug out of the charging and discharging interface 101. There is no need to manually pull out the cable charging and discharging plug again. Then, the pull plate 303 is pulled to the right. The pull plate 303 drives the lock head 315 to be pulled out of the locking groove 5031, and the locking plate 503 is unlocked. Under the action of the first spring 605, the clamping member 402 is driven to move upward, which in turn drives the locking plate 503 and the clamping plate 502 to move upward, so that the locking plate 503 moves to the unlocked position and the clamping plate 502 moves to the released position.

[0038] In some embodiments, a first telescopic rod 310 is provided in the mounting cavity 301. The first telescopic rod 310 passes through the second spring 309. One end of the first telescopic rod 310 is connected to the sliding member 308, and the other end of the first telescopic rod 310 is connected to the front wall surface of the mounting cavity 301.

[0039] By setting the first telescopic rod 310, the movement of the slider 308 can be guided, thereby making the movement of the slider 308 more stable.

[0040] In some embodiments, the rotating connection portion 501 further includes a first rotating shaft 5013, which passes through the rotating arm 5012 and the rotating shaft seat 5011. The rotating shaft seat 5011 is rotatably connected to the first rotating shaft 5013, and the rotating arm 5012 is rotatably connected to the first rotating shaft 5013. like Figure 8 As shown, the rotating connection part 501 also includes a fixed plate 5014, a mounting plate 5015, a sliding plate 5016, and a guide rod 5017. The fixed plate 5014 is connected to the cabinet 1. The mounting plate 5015 is disposed on the fixed plate 5014. The sliding plate 5016 and the mounting plate 5015 are spaced apart in the front-back direction. The sliding plate 5016 is slidable relative to the fixed plate 5014 in the front-back direction. The sliding plate 5016 is located in front of the mounting plate 5015. The guide rod 5017 passes through the sliding plate 5016 and the mounting plate 5015. A third spring 5019 is sleeved on the guide rod 5017. One end of the third spring 5019 is connected to the mounting plate 5015, and the other end of the third spring 5019 is connected to the sliding plate 5016. A blocking member 5018 is provided at the end of the guide rod 5017 away from the sliding plate 5016. Part of the first rotating shaft 5013 is located in front of the sliding plate 5016, and the first rotating shaft 5013 is provided with a protrusion 50131; When the clamping plate 502 is in the clamping position, the locking plate 503 is in the locking position, and the protrusion 50131 abuts against the sliding plate 5016; When the clamping plate 502 is in the released position, the locking plate 503 is in the released position, and the protrusion 50131 is disengaged from the sliding plate 5016; In other words, as the locking plate 503 and the pressing plate 502 move upward, the rotating arm 5012 rotates upward around the rotating shaft seat 5011, and the protrusion 50131 flips downward and abuts against the sliding plate 5016, which can limit the rotation range of the rotating arm 5012. At the same time, the third spring 5019 can buffer when the protrusion 50131 abuts against the sliding plate 5016, thereby extending the service life of the sliding plate 5016.

[0041] In some embodiments, the lower surface of the clamping plate 502 is provided with a pulley 5021, which is adapted to abut against the clamping member 402.

[0042] By providing pulleys 5021 on the lower surface of the pressure plate 502, it can be understood that the pressure plate 502 rotates around the rotating shaft seat 5011 via the rotating arm 5012. That is to say, during the pressing process of the pressure plate 502, the pressure plate 502 moves relative to the pressing member 402. Therefore, by providing rollers, it is convenient for the pressure plate 502 and the pressing member 402 to move relative to each other.

[0043] In some embodiments, the upper edge of the cable placement slot includes a first edge 4032 and a second edge 4033, the first edge 4032 having a first chamfer 4034 and the second edge 4033 having a second chamfer 4035.

[0044] It is understandable that by setting the first chamfer 4034 and the second chamfer 4035, it is easier to place the cable in the cable placement slot 403.

[0045] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this invention.

[0046] Furthermore, the terms "first" and "second" 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. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0048] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium.
