Background technology
Earthing device is used to conduct lightning current and it is scattered into the earth.At present; In 5.4 explanations about earthing device, require the length of artificial steel vertical junction terrain to be preferably 2.5m among the GB50057-2010 " Code for design of lightning protection of buildings ", the depth of burying should be less than 0.5m; And should be laid in below the local frozen soil layer, the heat release welding should be adopted in each junction.Thereby in the installation process, not only need a large amount of earth excavations, and in welding process, certainly lead to spark, be difficult to implement at inflammable and explosive hard in one's power soil layer.
Application number is that 200720081206.7 utility model patent discloses a kind of earth electrode that in the electric power system work progress, uses.Be made up of the body of rod, electronic joint, drill bit etc., inside has the liquid filling hole of hollow.This kind earth electrode does not clearly indicate lead-in wire junction, design imperfection; In addition, liquid filling hole is blocked by the sandstone in the soil easily, can't play corresponding effect; The 3rd, the elongated and hollow of the body of rod, under electric hammer or artificial hammering, easy deformation even fracture is difficult to be repeatedly used.
Summary of the invention
The purpose of the utility model is intended to overcome the deficiency of prior art, and providing a kind of can use on the inflammable and explosive place and the excavation ground that is difficult to break ground, and is convenient to installing/dismounting, but the earthing device that repeated multiple times is used.
The purpose of the utility model can realize through following technical scheme:
This earthing device comprises earth brace, and an end of described earth brace is provided with drill bit, and described drill bit is triangular taper, and the other end of described earth brace is provided with and drives bindiny mechanism, and described earth brace is provided with wiring member and screw thread.The effect of on described earth brace, selecting described triangular taper bit for use is through this kind drill bit, increases the ability of breaking ground of this device.The effect that described driving bindiny mechanism is set is to make described earth brace realize good being fixedly connected with Power Drive Unit such as electric hammer.The effect that described wiring member is set is to make described earth brace and earth connection can realize not having and be welded with to imitate to be connected.The effect that described screw thread is set be for drive described earth brace go into ground more smooth and easy.
The purpose of the utility model can also realize through following technical scheme:
Described driving bindiny mechanism is the hexagonal handle; This hexagonal handle is provided with annular groove; The effect that described hexagonal handle and described annular groove are set on the described earth brace is this structural design; Can be convenient to the installation and removal between the Power Drive Units such as described earth brace and electric hammer, and guarantee that the clamping between the Power Drive Units such as described earth brace and electric hammer is more fastening reliable; Described wiring member is an ear shape terminal block, and described screw thread is a fried dough twist type screw thread; Described ear shape terminal block is provided with two wiring holes; It is advantage simple in structure through said ear shape terminal block, as to be convenient to design and installation that described wiring member is selected the effect of ear shape terminal block for use, makes this device can be convenient to make with being convenient to and realizes being connected with earth connection.The effect that described screw thread is set to fried dough twist type screw thread is the ability of breaking ground that increases this device; Described fried dough twist type screw thread is positioned at the latter half of described earth brace.The effect that described fried dough twist type screw thread is positioned at the latter half of described earth brace is the ability of breaking ground that had both increased this device, also can reasonably control the difficulty and the workload of described earth brace being carried out screw thread processing; Described earth brace, described driving bindiny mechanism and described drill bit preferably are provided with nickel coating or chromium coating.Effect to described these parts nickel plating or chromium plating is to prevent that these parts from being corroded, and increases useful life; Described driving bindiny mechanism and drill bit adopt the high-strength alloy material.It is the intensity that strengthens these stressed members that described these parts adopt the effect of high-strength alloy material, increases the service life.
The beneficial effect of the utility model: because through described triangular taper bit, driving bindiny mechanism and screw thread; Make described earth brace have the very strong ability of breaking ground; The solderless that can be grounded bar and earth connection through described wiring member connects in succession; Power Drive Unit such as available electric hammer and artificial dual mode realize hammering go into and take out, and guaranteed that described earth brace possesses sufficient intensity.So, but the utlity model has the simple and convenient repeated multiple times of installing/dismounting use, need not implement to weld, to destroying less and can realize the advantage of Fast Installation in the builder's yard.
