Abstract
The utility model relates to a grounding wire connecting board used for a power transmission circuit tower. The grounding wire connecting board used for the power transmission circuit tower includes a connection upper part, a connection middle part and a connection lower part connected with each other and formed integrally. An installation hole is arranged in the connection upper part. A groove is arranged in the lower part of the connection lower part. According to the utility model, a prior round hole is changed to be a waist-shaped hole, so that a problem that the installation cannot be performed smoothly when deviation appears in the pitch of a grounding end of the power transmission circuit tower in the prior art is solved. The grounding wire connecting board used for the power transmission circuit tower also includes a groove, so that the joint area when connecting is enlarged substantially and the reliability of connecting with a connection pipe and the conductivity are guaranteed.
Description
Technical field
The utility model relates to the grounding connection apparatus field, relates in particular to a kind of earth connection connecting plate for electric power line pole tower.
Background technology
Electric power line pole tower is carrying higher working voltage, must have good earthing device when operation, to prevent because of factor cause damage of equipment and personnel casualty accidentses such as electric leakage, thunderbolts, as shown in Figure 1 and Figure 2, existing ground wire connecting device comprises connecting plate 1, described connecting plate 1 and tube connector 2 welding, but there is following shortcoming in the ground wire connecting device of this structure:
(1) connecting plate and tube connector welding position are unreasonable, and both bonding areas are little, are prone to the situation that the through-current capability that causes because of connecting plate or tube connector local corrosion descends in long-term use procedure.
(2) have circular hole 101 on connecting plate, when installing and the pitch-row of the earth terminal of electric power line pole tower can't install smoothly when deviation occurring.
The utility model content
The applicant provides a kind of simple in structure, reliable a kind of earth connection connecting plate for electric power line pole tower of connection for above-mentioned existing issue, has to connect reliably, preferably electric conductivity.
The technical scheme that the utility model adopts is as follows:
A kind of earth connection connecting plate for electric power line pole tower comprises that being connected to each other the shape all-in-one-piece connects top, connects the middle part and connect the bottom, has installing hole connecting on top, has groove connecting the bottom.
Its further technical scheme is:
Described connection middle part be bending part, is positioned at the connection top that connects the two ends, middle part and is connected the lower parallel layout.
At least one is mounting hole connecting installing hole that top has.
The beneficial effects of the utility model are as follows:
The utility model changes original circular hole into mounting hole, the problem that can't install smoothly when having avoided in the past pitch-row because of the earth terminal of electric power line pole tower deviation to occur, also have groove on the utility model, improved greatly the bonding area when connecting, guaranteed the reliability that is connected with tube connector and guaranteed conductivity.
Description of drawings
The structural representation that Fig. 1 is connected with tube connector for existing ground wire connecting device.
Fig. 2 is the end view of Fig. 1.
Fig. 3 is the main TV structure schematic diagram that the utility model is connected with tube connector.
Fig. 4 is the end view of Fig. 3.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.
As shown in Figure 3, Figure 4, the utility model comprises that being connected to each other the shape all-in-one-piece connects top 201, connects middle part 203 and connect bottom 204, has installing hole connecting on top 201, has groove connecting the bottom.Connecting middle part 203 be bending part, the connection top 201 that is positioned at 203 two ends in the middle part of connecting be connected bottom 204 and be arranged in parallel.As shown in Figure 3, at least one is mounting hole 202 connecting installing hole that top 201 has, is positioned at mounting hole 202 tops, also has circular hole in connecting on top 201.
Installation process of the present utility model is as follows:
As shown in Figure 3, Figure 4, weld after utilize connecting the groove that has on bottom 204 and tube connector 3 docking, the area of welds joint 3 obviously increases, greatly improved the reliability that connects, then the mounting hole 202 that has on utilization connection top 201 aligns with the earth terminal of electric power line pole tower, even pitch-row exists deviation also can move to make up by mounting hole 202 problem of pitch-row, realize both smooth installations smoothly.
The utility model changes original circular hole into mounting hole, the problem that can't install smoothly when having avoided in the past pitch-row because of the earth terminal of electric power line pole tower deviation to occur, also have groove on the utility model, improved greatly the bonding area when connecting, guaranteed the reliability that is connected with tube connector and guaranteed conductivity.
Above description is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range is referring to claim, in the situation that without prejudice to basic structure of the present utility model, the utility model can be done any type of modification.
