Abstract
The utility model discloses a mobile distribution box with a grounding device. The mobile distribution box comprises a box body. One side of the box body is provided with a drilling machine. A drill stem passes through the drilling machine. The outer surface of the drill stem is provided with a spiral groove. The drill stem is made of metal. The installing steps of the mobile distribution box comprises the steps of well supporting and mounting the distribution box first, then starting the drilling machine, drilling the drill stem into the ground, turning off the drilling machine when the drill stem reaches the required depth, and electrically connecting the drill stem with the box body of the distribution box. The automatic grounding of the box body of the distribution box is achieved and the grounding efficiency is high. By means of the drilling machine, the drill stem for grounding can reach a rather deep place, so that the resistance can be reduced and favorable grounding can be achieved.
Description
Technical field
The utility model relates to a kind of distribution box, specifically, is a kind of mobile power distribution box with ground.
Background technology
Distribution box is at the essential equipment in a lot of electricity consumption fields, and it provides electric energy for electricity consumption place, is equiped with the electric components such as switch, voltameter, voltmeter, ammeter, circuit breaker in distribution box.And Moveable distribution box is mainly used in the fields such as construction, road construction, mining.In order to prevent from causing because of electric leakage the generation of electric shock accidents, need to be by the earthing of casing of distribution box.But for Moveable distribution box, a lot of application places do not have suitable ground connection facility, need to install voluntarily.In prior art, be all generally that efficiency is low, weak effect by manually burying ground wire underground.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of mobile power distribution box with ground, can realize Auto-mounting ground wire, and by the distribution box earthing of casing, efficiency is high, effective.
In order to solve the problems of the technologies described above, the utility model provides a kind of mobile power distribution box with ground, comprises casing, one side of described casing is provided with rig, in described rig, be equipped with drilling rod, described drilling rod outer surface is provided with spiral groove, and described drilling rod is made by metal material.
Further, described drilling rod has multistage, and multistage drilling rod is end to end successively.
Further, be provided with axial passage in described drilling rod, the bottom of described passage is in the drill bit place of drilling rod opening.
Further, described opening is opened in the groove of described drill bit.
Further, described opening is towards the outer side of described drill bit.
Further, in described passage, be equipped with conductor wire, the end of described conductor wire passes also along continuous straight runs edge from described opening and stretches.
Further, described conductor wire upper end is electrically connected to the casing of distribution box.
Further, described conductor wire is bare wire, and exposed conductor wire directly contacts to form with described drilling rod and is electrically connected to.
Further, described passage has a plurality of.
Mobile power distribution box with ground of the present utility model when mounted, has first installed distribution box, then starts rig, drilling rod is pierced underground, closes rig after reaching desired depth, then drilling rod is electrically connected to the casing of distribution box.The utility model can be realized the automatic earthing of distribution box body, and efficiency is high.And owing to having adopted rig, the drilling rod of ground connection can reach the very dark degree of depth, has reduced resistance, realize better ground connection.
Accompanying drawing explanation
Fig. 1 is the structural representation of mobile power distribution box with ground of the present utility model.
Fig. 2 is the cutaway view that drilling rod pierces under ground portion.
In figure: 1. casing, 2. rig, 3. drilling rod, 4. groove, 5. passage, 6. conductor wire, 7. end, 8. soil.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, so that those skilled in the art can better understand the utility model being implemented, but illustrated embodiment is not as to restriction of the present utility model.
As shown in Figure 1, mobile power distribution box with ground of the present utility model, comprises casing 1, in a side of casing 1, is provided with rig 2, is equipped with drilling rod 3 in rig 2, and drilling rod 3 outer surfaces are provided with spiral groove 4, and drilling rod 3 is made by metal material.When mounted, first installed distribution box, then started rig 2, drilling rod 3 has been pierced underground, closed rig 2 after reaching desired depth, then drilling rod 3 has been electrically connected to the casing 1 of distribution box.The spiral groove 4 of drilling rod 3 outer surfaces for discharging the soil of drill hole, the resistance while holing to reduce when holing.The utility model can be realized the automatic earthing of distribution box body, and efficiency is high.And owing to having adopted rig, the drilling rod of ground connection can reach the very dark degree of depth, has reduced resistance, realize better ground connection.
Preferably, drilling rod 3 is comprised of multistage drilling rod, and multistage drilling rod is the longer drilling rod of end to end formation successively.The object of segmental structure is to be convenient to mobile and transportation.
As further optimization of the present utility model, can be at the interior axial passage 5 that arranges of drilling rod 3, the bottom of passage 5 is in the drill bit place of drilling rod 3 opening.Preferably, the opening of passage 5 is opened in groove 4 places of drill bit and towards the outer side of drill bit.The effect of passage 5 has two: the first, when boring, can in passage 5, inject water under high pressure, and water spiral groove 4 along drilling rod 3 outer surfaces from opening flows out flows back to ground, so that the soil of drill hole is gone out, the resistance in the time of can further reducing boring; Second, after boring completes, one conductor wire 6 is inserted from passage 5, drilling rod 3 is stretched out from the opening of passage 5 bottoms in the end 7 of conductor wire 6, again conductor wire 6 is imposed to certain pressure and twisting resistance, the end 7 of conductor wire 6 is extended at the interior along continuous straight runs of soil 8, and conductor wire 6 upper ends are electrically connected to the casing 1 of distribution box, or adopt exposed conductor wire 6 directly to contact formation electrical connection with drilling rod 3.So, can further increase the contact area of earth connection and soil 8, thereby reduce earth resistance, improve earthing effect.Passage 5 preferably has a plurality of.
The above embodiment is only the preferred embodiment for absolutely proving that the utility model is lifted, and protection range of the present utility model is not limited to this.Being equal to that those skilled in the art do on the utility model basis substitutes or conversion, all within protection range of the present utility model.Protection range of the present utility model is as the criterion with claims.
