Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of lightning protection grounding for transmission lines in power systems, and specifically to a construction device for externally applying a grounding to a concrete pile foundation of a transmission line tower. Background Art
[0002] A transmission line is an important part of the five links of "power generation, power transmission, power transformation, power distribution, and power utilization" in a power system. A large number of transmission line towers are the basic power facilities in the power transmission link. Generally, power lines are erected outdoors without lightning protection by lightning rods. During actual operation, it is often necessary to prevent lightning strikes on the iron tower or the conductor to avoid flashover breakdown of the suspension insulators of the transmission line caused by high-amplitude lightning current, and then cause a short-circuit grounding fault of the transmission line.
[0003] In order to prevent lightning strike accidents on transmission lines in power engineering, a grounding device is installed on each iron tower during the construction of the power iron tower. On the one hand, the grounding device includes the concrete pile foundation of the tower, and on the other hand, it includes a horizontally laid grounding body excavated manually. The two together constitute the lightning current discharge channel of the grounding grid of the transmission line tower, ensuring that the transmission line tower can quickly discharge current to the ground after being struck by lightning and avoiding lightning trip faults. A good grounding channel and a small grounding resistance value are important indicators for measuring the performance of the grounding device of a power tower. The traditional concrete pile foundation of a transmission line tower mainly relies on the steel bar framework in the concrete for current dissipation. Since the resistivity of the concrete medium is very high, it is difficult for the lightning current to dissipate to the surrounding soil through the concrete pile foundation, resulting in a very high grounding resistance value of the pile foundation. Only by later excavating a grounding trench can the grounding resistance be reduced.
[0004] In order to reduce the grounding resistance of the concrete pile foundation of the pole tower, when constructing the transmission line pole tower of the actual power system, a layer of flexible conductive material is generally applied externally for grounding resistance reduction, such as flexible graphite cloth, flexible graphite cable body, etc. These flexible grounding materials can conduct the lightning strike current from the internal steel bar framework to the surrounding soil, relieve the current dissipation pressure in the reinforced concrete pile foundation, and greatly reduce the overall grounding resistance of the transmission line pole tower. This kind of external grounding device for the concrete pile foundation has gradually become a common grounding construction method in the process of pole tower construction. Since the external grounding device of the tower foundation is tied after the formwork of the transmission line pole tower concrete pile foundation is removed and air-dried for curing, this process mainly relies on manual binding at present. When the overall height of the transmission line pole tower concrete pile foundation is below 2m, it can be completed. If the pile foundation exceeds 2m, climbing construction operations are required, but the climbing ladder also makes it difficult to bind the external grounding material. The overall laying efficiency and uniformity of the external flexible grounding material often fail to meet the construction requirements. Therefore, designing and preparing a construction device for the external grounding material of the transmission line pole tower concrete pile foundation has great engineering application value for improving construction efficiency, ensuring the external application effect, reducing the risk of manual operation, etc., and has a broad promotion and application prospect.

[0043] During actual use, when the buckle plate 3 is buckled on one side of the transmission line tower 2 and pushed forward, the transmission line tower 2 simultaneously squeezes the guiding slopes 13 on the surfaces of the two groups of baffles 12. At this time, the distance between the two groups of baffles 12 becomes larger, and the connection between the notch 5 and the elastic clip 6 is elastically bent. The rubber connecting piece 7 wraps around the connection gap between the notch 5 and the elastic clip 6 to prevent the connection between the notch 5 and the elastic clip 6 from breaking. During the process of pushing the buckle plate 3, the rotating rod 14 rolls along the transmission line tower 2. Until the two groups of baffles 12 pass over the transmission line tower 2, the elastic clip 6 rebounds and the distance between the two groups of baffles 12 returns to its original position. At this time, the rubber backing plate 4 is clamped between the transmission line tower 2 and the buckle plate 3, and the rubber clip strip 8 is clamped between the elastic clip 6 and the transmission line tower 2. The locking bolt 16 is passed through the reserved holes 15 on the surfaces of the two groups of baffles 12 and then locked. At this time, the distance between the two groups of baffles 12 is reduced, and the two groups of elastic clips 6 clamp the transmission line tower 2, and the rubber cushion block 11 is squeezed and inserted into the installation groove 10, and the hard clamping protrusion 9 clamps the surface of the transmission line tower 2, realizing the firm fixation of the buckle plate 3 on the transmission line tower 2. In order to reinforce the firmness of the installation of the transmission line tower 2 and the buckle plate 3, the traction collar 20 straightens the traction rope body 21 and winds it around the wire bundling column 17, and passes the collar 20 through the rubber ball 19 and slews it on the limit post 18. In this way, the straightened traction rope body 21 ensures that the distance between the two groups of baffles 12 will not become larger after the locking bolt 16 becomes loose, thus preventing the buckle plate 3 from being firmly fixed on the transmission line tower 2; after the grounding plug 24 is pushed into the connecting frame 22, the push block 34 is toggled to slide along the guide rail strip 33, and the push block 34 squeezes the positioning plug 27 to insert into the positioning socket 25. During this process, the positioning plug 27 drives the traction bar 28 to squeeze the rubber clamping block 31 through the insertion rod 30. When one end of the push block 34 slides into the other guide rail strip 33, continue to toggle the push block 34 to squeeze the clamping strip 39, and the clamping strip 39 props up the elastic rubber belt 40 to deform. When the card slot 37 and the clamping strip 39 correspond, the elastic rubber belt 40 rebounds and pushes the clamping strip 39 to reset. At this time, the clamping strip 39 is inserted into the card slot 37 to prevent the push block 34 from moving. At this time, both ends of the push block 34 are respectively inserted into the two guide rail strips 33, and the push block 34 blocks the positioning plug 27, thus realizing the rapid and firm assembly of the connecting frame 22 and the grounding plug 24; when it is necessary to expand the grounding area of the support plate 42, pinch the pull bar 48 to traction a plurality of embedded rods 45 to rotate 180 degrees around the corresponding limit shaft 44, and then bury the embedded rods 45 in the soil layer.
