[0002] A digital substation is a modern substation that achieves information sharing and interoperability among intelligent electrical devices within the substation through a hierarchical construction of intelligent primary equipment (such as electronic instrument transformers and intelligent switches) and networked secondary equipment.

[0003] The prior art discloses a digital substation power distribution device with application number CN202123323129.0, including a power distribution device body, a horizontal base at the bottom of the power distribution device body, circular cavities at the four corners of the base, and circular holes in the middle of the upper cavity walls of the multiple circular cavities. A buffer mechanism is fixed between the interior of the multiple circular cavities and the lower end of the power distribution device body. Rectangular grooves are longitudinally formed on the left and right sides of the lower end of the base. Hollow plates are slidably connected to the upper sides of the interior of two rectangular grooves. Universal wheels are fixedly connected to the front and rear ends of the lower outer walls of the two hollow plates. Mounting holes are vertically formed in the middle of the upper groove walls of the two rectangular grooves, and threaded holes are vertically formed in the middle of the upper walls of the two hollow plates. This utility model improves vibration reduction, reduces the risk of damage to internal components due to vibration, and extends service life; it also facilitates movement during the transportation of the power distribution device.

[0004] The aforementioned lead screw pushes the hollow plate downwards, and the hollow plate drives the casters to move up and down, making it easy to move the device. However, since the hollow plate is supported by only one lead screw, it is easy for the hollow plate to slide on the surface of the lead screw, causing the device to be unable to move.

The electric push rod is mounted on the inner wall surface of the limiting shell, the limiting shell is mounted on the inner wall surface of the sliding shell, and the baffle plate is threaded to the surface of the sliding shell.

[0009] Preferably, the sliding housing is movably connected to the outward end of the support platform, the baffle is movably connected to the outer surface of the support platform, and the baffle is threaded to the outer end surface of the sliding housing, thereby locking and fixing the position of the electric push rod to prevent the electric push rod from falling.

[0010] Preferably, the bidirectional lead screw is installed at the outward end of the metal frame, and the metal frame is installed on the upper surface of the support platform. The metal frame drives the bidirectional lead screw to move downward, and the metal frame can determine the position of the bidirectional lead screw.

[0011] Preferably, there are two drive motors, which are arranged left and right. The rotors of the drive motors drive the bidirectional lead screw to rotate. The bidirectional lead screw can adjust the movement of the baffle plates towards each other. The baffle plates can drive the electric push rod to move back and forth, thereby adjusting the position of the baffle plates.

[0012] Preferably, there are two blocking blocks, which are arranged one in front of the other. The two blocking blocks can limit and fix the position of the caster wheel, thereby limiting the position of the support platform.

The drive motor 11 is mounted on the front of the metal frame 12. There are two drive motors 11, which are distributed left and right. The rotor of the drive motor 11 drives the bidirectional lead screw 14 to rotate. The bidirectional lead screw 14 can adjust the movement of the baffle 136 towards each other. The baffle 136 can drive the electric push rod 131 to move back and forth, thereby fixing the position of the baffle 136. The drive motor 11 is fixedly connected to the front of the bidirectional lead screw 14. The bidirectional lead screw 14 is mounted on the outward end of the metal frame 12. The metal frame 12 is mounted on the upper surface of the support platform 3. The metal frame 12 drives the bidirectional lead screw 14 to move downward.

[0028] The blocking assembly 13 includes an electric push rod 131, a connector 132, a blocking block 133, a limiting housing 134, a sliding housing 135, and a baffle plate 136. The connector 132 is inserted into the outward end of the blocking block 133. There are two blocking blocks 133, which are arranged front and back. The two blocking blocks 133 can limit and fix the position of the caster wheel 4, thereby limiting the position of the support platform 3.

[0033] Pushing the metal frame 12 downward, the metal frame 12 is also on the upper surface of the support platform 3, so that the metal frame 12 drives the baffle plate 136 to move downward. The baffle plate 136 and the upper end of the sliding housing 135 are fixed by threads, which can determine the position of the baffle plate 136.
