Abstract

The utility model provides a novel wire reel, which includes a connecting column, a rotating shaft interspersed in the connecting column and having the same axial direction as the connecting column, and limiting discs on both sides of the connecting column. The cross section of the limiting disc is larger than The cross-section of the connecting column, the reel also includes a base and a handle connected to the outer surface of the limit plate on one side, the rotating shaft extends out of the connecting column, the base is composed of a single tube, one end of which is connected to the One end protruding from the rotating shaft is connected, and it extends outwards and downwards below the wire reel, then extends laterally at the bottom of the wire reel to form a U shape, and finally extends inwards and upwards to be higher than the top of the wire reel and extends axially on the connecting column to form a handle. Due to the adoption of the technical solution of the utility model, the utility model adopts the improved wire reel as the wire winding reel for the ground resistance test. The base of the utility model is formed by winding a single tubular object, which is stable, uses less materials, and has a simple structure and is convenient to use.

Description

A kind of novel drum

Technical field

The utility model relates to a kind of drum.Be particularly related to a kind of wire drum.

Background technology

Ground connection is the very important link that guarantees life safety and electrical equipment and overvoltage protection normal operation.During newly-built substation, must test its grounding resistance.Whether the substation of operation also needs grounding resistance of test in every 5 years, good to detect its ground state.

Method of lines is commonly used in the test of grounding resistance.During measurement, need two of layouts respectively to be about the catercorner length 3-5 of substation testing wire doubly.According to general 110kV substation diagonal line, be about about 80 meters calculating.The length of these two lines is just 250-400 rice.

Because earth-continuity test and earth resistance have quite similar process, all have unwrapping wire, take-up and test link, but the earth resistance time is long, efficiency is low.

Wherein, the longest when the placement conductor loop is saved, and other link used times are few and average.In placing the wire process, the line segment coiling completes in the time of need to again opening route wires, and upper strand and the lower burst of situation that wire is wound around easily occur.Just need to arrange the wire that is wound around this moment.If add up while finding that wire is not wound around by timing, the unwrapping wire process will be very smooth.And arrange, be wound around wire process trouble and length consuming time.The manual time that connects two wire heads needs 1 minute at least.

Summary of the invention

technical problem to be solved in the utility model is to provide a kind of drum that shortens the earth resistance work-hours, for this reason, the utility model is by the following technical solutions: it comprises joint pin, intert in joint pin and with axially identical rotating shaft of joint pin, and the position-arresting disk of joint pin both sides, the cross-sectional plane of described position-arresting disk is greater than the cross-sectional plane of joint pin, described drum also comprises base, be connected to the turning handle of a side position-arresting disk outside face, described rotating shaft is stretched out outside joint pin, described base consists of single pipe, the one end is connected with the end that rotating shaft is stretched out, it outwards extends downward below drum, online tray bottom horizontal expansion forms U-shaped again, finally inwardly extend upwardly to higher than the drum top and on joint pin is axial and extend to form portable handle.

Adopting on the basis of technique scheme, the utility model can also be by the following technical solutions:

Described portable handle outer end has lines.

Described portable handle can outwards make progress or extend internally in joint pin week.

Owing to having adopted the technical solution of the utility model, the utility model adopts the drum the improved wire spool as earth resistance.Base of the present utility model adopts single pipe coiling to form, and is fixed stably, materials'use is few, and simple in structure, easy to use.

The accompanying drawing explanation

Fig. 1 is schematic diagram of the present utility model.

Fig. 2 is lateral plan of the present utility model.

The specific embodiment

With reference to accompanying drawing.

The utility model comprises joint pin 7, intert in joint pin 7 and with axially identical rotating shaft 9 of joint pin, and the position-arresting disk 6 of joint pin both sides, line 8 is wrapped on joint pin.The cross-sectional plane of described position-arresting disk 6 is greater than the cross-sectional plane of joint pin 7, can not understand so that line 8 only is wrapped on joint pin 7 outer not moving.

Described drum also comprises base 1, is connected to the turning handle 4 of side position-arresting disk 6 outside faces, described rotating shaft 9 is stretched out outside joint pin 7, described base 1 consists of single pipe, the one end is connected with the end that rotating shaft 9 is stretched out, it outwards extends downward below drum, online tray bottom horizontal expansion forms U-shapedly again, finally inwardly extends upwardly to higher than the drum top and at joint pin and extends to form portable handle on axially.

Described portable handle 5 outer ends have lines 21, during operation, increase friction force and are difficult for slippage.

Described portable handle 5 can outwards make progress or extend internally in joint pin week.

Claims

1. A new type of wire reel, which includes a connecting column, a rotating shaft inserted in the connecting column and axially the same as the connecting column, and limiting disks on both sides of the connecting column, the cross section of the limiting disk is greater than that of the connecting column Cross-section, the reel also includes a base, a rotating handle connected to the outer surface of the limit plate on one side, and the rotating shaft extends out of the connecting column, and it is characterized in that the base is composed of a single tube, one end of which is connected to the One end protruding from the rotating shaft is connected, and it extends outwards and downwards below the wire reel, then extends laterally at the bottom of the wire reel to form a U shape, and finally extends inwards and upwards to be higher than the top of the wire reel and extends axially on the connecting column to form a handle.

2. A new type of reel according to claim 1, characterized in that the outer end of the handle has lines.

3. A new type of reel according to claim 1 or 2, characterized in that the handle can extend outward or inward along the circumference of the connecting column.
