Description

Technical Field

[0001] The present invention relates to the technical field of power equipment, and in particular to a connection mechanism for power grid energy storage power station equipment. Background Art

[0002] During the operation, maintenance, and inspection of energy storage power stations, correct and reliable installation of grounding wires is one of the most critical measures to ensure personal safety and prevent electric shock accidents. Grounding wires need to be connected to isolated live conductors, usually cables, equipment housing frames, DC busbars, etc., and usually need to be connected to the ground through insulating connection devices such as insulating rods.

[0003] Although the traditional insulating connection structure can achieve basic connection, it has obvious shortcomings: first, the clamping structure is single and can only be connected to bolts or small-diameter cables through hooks. It cannot adapt to special-shaped connection points such as busbars and large-diameter cables, resulting in unstable contact during operation; second, the grounding cable lacks an effective storage mechanism. It needs to be repeatedly coiled when manually retracted, which is not only inefficient, but also causes the cable to twist and tangle, and the insulation layer to wear. The existing device does not integrate a reeling mechanism. The exposed storage of the cable is susceptible to oil corrosion, shortening its service life. In addition, the lead-out length cannot be flexibly adjusted as needed during operation, and it is easy to interfere with surrounding components in a narrow equipment cabin; third, there is a lack of support mechanism for the cables and connection points during operation. The cables are prone to friction with the equipment casing due to their own weight, which poses a risk of insulation damage. Especially when connecting to high-altitude busbars, it is necessary to manually hold the insulating rod throughout the process, which is labor-intensive and poses a safety hazard. Therefore, a connection mechanism for grid energy storage power station equipment is proposed. Summary of the Invention

The two sets of clamping assemblies 4 in the device are respectively connected to the grounding pile and the location to be inspected. In actual applications, the cables 5, the equipment housing, and the busbar need to be grounded. The clamping assembly 4 can be used to connect the bolts on the equipment cabinet housing, the busbar, and cables 5 with different outer diameters.

The winding drum 610 rotates under the driving action of the second gear 604, and the second gear 604 is meshed with the first gear 603. When the winding drum 610 rotates, the threaded rod 601 can synchronously drive the movable seat 607 to move up and down. A limiting ring 608 is provided on the movable seat 607. Under this action, the cable 5 can be evenly wound and stored on the outer wall of the winding drum 610, and when in use, the cable 5 released from the outer wall of the winding drum 610 can be pulled out for use by driving the winding drum 610 to rotate and cooperating with the user to pull the end of the cable 5. Two sets of winding components 6 are provided inside the shell 1. The middle position of the cable 5 can be fixed by the two sets of winding components 6, and then the two ends can be wound up respectively. The user can flexibly pull any end of the cable 5 to make it extend outward for use, thereby enhancing the flexibility of the device when used in different scenarios.

[0033] When the cable 5, busbar or bolt is clamped by the clamping assembly 4, it can be used in conjunction with the support assembly 2, wherein the lifting frame 202 is lifted upward by multiple electric telescopic rods 201, which can make the cross bar 205 rise. After the cross bar 205 is adjusted to a suitable height according to actual conditions, the upper ends of the two extension rods 206 arranged at both ends of the cross bar 205 cooperate with the arc block 207 to support the cable 5 and the combination of the insulating rod 3 and the clamping assembly 4. When the clamping assembly 4 is connected to the cable 5, the flexible cable 5 is sunken at the connection under the action of the gravity of the insulating rod 3 and the clamping assembly 4. At this time, the end of the insulating rod 3 can be inserted into the installation rod on the first plug-in tube 208, and the insulating rod 3 and the clamping assembly 4 can be supported by the cross bar 205. The ends of the two extension rods 206 support both sides of the connection between the cable 5 and the clamping assembly 4 to prevent the cable 5 from being damaged by force. At the same time, the two extension rods 206 can also support the combination of the insulating rod 3 and the clamping assembly 4. For example, when the busbar is connected, the busbar is clamped between the two clamping plates 406. If the busbar is vertically set, the structure after the insulating rod 3 and the clamping assembly 4 are combined is horizontally set. At this time, the user can support the horizontally placed insulating rod 3 and the clamping assembly 4 through the two extension rods 206 to ensure the reliability of the connection between the busbar and the clamping assembly 4. When not in use, the vertical rod 203, the reinforcing rod 204, the cross rod 205, the extension rod 206 and the arc block 207 can be stored on the outside of the shell 1 through the synchronous contraction of multiple electric telescopic rods 201.
