Description

Technical Field

[0001] The utility model relates to a power grid dispatching device, in particular to a portable power grid dispatching device. Background Art

[0002] Grid dispatching is an effective management method adopted to ensure the safe and stable operation of the power grid, reliable external power supply, and orderly progress of various types of power production. The specific work content of power dispatching is based on the data information fed back by various information collection equipment or the information provided by monitoring personnel, combined with the actual operation parameters of the power grid, such as voltage, current, frequency, load, etc., and comprehensively considers the progress of various production work, judges the safety and economic operation status of the power grid, issues operating instructions through telephone or automatic system, and directs on-site operators or automatic control systems to make adjustments, such as adjusting generator output, load distribution, switching capacitors and reactors, etc., so as to ensure the continuous safe and stable operation of the power grid. Grid dispatching equipment is usually used when grid dispatching is needed.

[0003] Although the existing power grid dispatching equipment is widely used, it still has some defects. For example, the existing power grid dispatching equipment is usually box-type, which requires manual handling or machine transportation when moving, and is not portable enough. In addition, due to the different heights of different power cabinets, when working in a higher power cabinet, it is impossible to take the tools inside the power grid dispatching equipment, and the working efficiency is low. Therefore, a portable power grid dispatching equipment is proposed to address the above problems. Summary of the invention

[0004] The utility model provides a portable power grid dispatching device, which aims to make the power grid dispatching equipment more portable and capable of being telescopic to adapt to different heights.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A portable power grid dispatching device, comprising a bottom plate, a plurality of storage boxes are fixedly arranged on the upper surface of the bottom plate, drawers are slidably connected to the plurality of storage boxes, an air intake cylinder is arranged at the center of the upper surface of the bottom plate, the air intake cylinder penetrates the bottom plate and is arranged between the storage boxes, a vertically arranged fixing rod is arranged inside the air intake cylinder, a pressure plate is fixedly connected to the bottom end of the fixing rod, a fixing ring is fixed to the top end of the inner wall of the air intake cylinder, and the fixing rod is sleeved in the middle of the fixing ring;

[0007] Several air intake components for preventing gas backflow are provided on the pressure plate and inside the air intake cylinder. The air intake components located inside the air intake cylinder are connected to an air intake pipe, and the end of the air intake pipe close to the air intake cylinder is connected to an air outlet pipe which is inclined and communicated with the air intake pipe, and the bottom end of the air outlet pipe is fixedly connected to an exhaust valve which communicates with the air outlet pipe, and the end of the air intake pipe away from the air intake component is provided with a lifting component for raising and lowering the height of the bottom plate, and a connecting plate is fixedly connected to the outer side of the lifting component near the lower end, and a universal wheel is fixed to the bottom end of the connecting plate.

[0008] Furthermore, the air intake assembly includes a connecting pipe, a fixing plate is fixedly provided at the top end of the connecting pipe, a plurality of air holes are provided on the fixing plate, a return spring is fixedly provided at the connecting pipe and is fixedly connected to the lower end of the fixing plate, a sealing ball is fixedly connected to one end of the return spring away from the fixing plate, and when the sealing ball is pushed open, the return spring drives the sealing ball to fit against the inner wall of the connecting pipe.

[0009] Furthermore, the end of the connecting tube located inside the air intake cylinder and below the pressure plate away from the air intake cylinder is fixedly connected to the air intake pipe and is arranged through the air intake pipe, and the outer wall of the sealing ball is in contact with the inner wall of the connecting tube.

[0010] Furthermore, the lifting assembly includes a lifting cylinder fixedly connected to one end of the air intake pipe away from the connecting pipe and vertically arranged, a piston is provided inside the lifting cylinder and fits with the inner wall of the lifting cylinder, the bottom end of the piston is fixedly connected to a vertically arranged lifting rod, the outer wall of the lifting rod is provided with a sealing ring fixedly connected to the inner wall of the lifting cylinder for preventing dust from entering the lifting cylinder, and the bottom end of the lifting rod is fixedly connected to a rubber pad.

[0011] Furthermore, the storage boxes are symmetrically distributed on the upper surface of the bottom plate near two edges, and the outer side of the pressure plate is arranged in close contact with the inner wall of the air intake cylinder.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. The utility model is provided with an air intake assembly and a lifting assembly, which drives the pressure plate to slide on the inner side of the air intake cylinder by moving the fixed rod. When the pressure plate moves downward, the air inside the air intake cylinder enters the inner side of the connecting pipe through the air vent and pushes open the sealing ball. The air inside the air intake cylinder enters the inner side of the lifting cylinder through the air intake pipe. The reset spring resets and drives the sealing ball to fit tightly with the inner side of the connecting pipe again. The increase in pressure drives the piston and the lifting rod to move downward, so that the rubber pad contacts the ground until the bottom plate rises to a suitable height. The lifting assembly can make the device adapt to power cabinets of different heights. When the work is finished and the height of the device needs to be lowered, the exhaust valve is opened. Due to the dead weight of the device driving the device to descend, the air inside the lifting cylinder is discharged through the exhaust pipe, so the height of the device can be lowered. By enabling the device to be lifted and lowered, the work efficiency is improved.

[0014] 2. In the utility model, the device is made more portable by providing a connecting plate and universal wheels. When the device needs to be moved, the device can be directly pushed, and the universal wheel at the bottom of the connecting plate can be rotated to drive the device to the desired position. When the device needs to be used, the device is raised, and the lifting rod is extended to drive the rubber pad to descend so that the universal wheel rises, avoiding the universal wheel from contacting the ground, thereby making the device more stable when used.
