Specific embodiment
With reference to the accompanying drawing, the specific embodiment of the present invention is described in detail, it is to be understood that of the invention
Protection scope be not limited by the specific implementation.
As shown in Figures 1 to 8, the power grounding pile of a kind of power engineering provided in an embodiment of the present invention, comprising:
Cylindrical shell 10, lower end gathering is tapered, internal to have a containing cavities 101, and upper end has opening；
Flight 11, helically the outside of the cylindrical shell 10 is arranged in ascending manner, in embedded cylindrical shell 10,
Convenient for by power grounding pile turn to be inserted into underground；
Drive rod 20 is movably disposed in the containing cavities 101；
Several tensile resistance rods 24 are located in the containing cavities 101, and tensile resistance rod 24 is arranged along the extending direction of drive rod 20,
The even side for being distributed in tensile resistance rod 24；Wherein,
The reception hole for accommodating the tensile resistance rod 24 is offered on the cylindrical shell 10, the tensile resistance rod 24 can be along institute
It states reception hole and stretches out the containing cavities 101, when the drive rod 20 moves up and down, drive the extended or retracted institute of the tensile resistance rod 24
State containing cavities 101.
Specifically, several recessing grooves 203 are offered on the drive rod 20, preferably tensile resistance rod 24 is along driving in the present embodiment
20 extending direction of bar is five layers, and every layer is three, is circumferentially uniformly distributed along drive rod 20, the quantity and tensile resistance rod of recessing groove 203
24 quantity corresponds, and the recessing groove 203 has a drive surface from top to bottom gradually inwardly collapsed, i.e., by tensile resistance rod 24
Lateral surface tilt open up inwardly downward, one end of the tensile resistance rod 24 is located in the recessing groove 203, the other end pass through it is described
Reception hole, in the present embodiment, preferably the axial line of reception hole is arranged along the direction of axis line perpendicular to drive rod 20.When embedded,
Cylindrical shell 10 is first embedded to underground, then external force forces drive rod 20 to move downward, when drive rod 20 moves downward, tension
Bar 24 can only move under the action of reception hole along perpendicular to 20 direction of axis line of drive rod, therefore tensile resistance rod 24 is in drive surface
Under driving, meeting is gradually protruding and buries into soil.Since tensile resistance rod 24 is to be inserted directly into soil, and on different height
Tensile resistance rod 24 be inserted into soil depth it is also different, therefore when tensile resistance rod 24 be inserted into soil after, though rotate cylindrical shell 10 or
Drawing cylindrical shell 10 all can not extract easily it.
For the stretching containing cavities 101 for keeping drive rod 20 more reliable and more stable, the opposite two sides of the recessing groove 203
Guide chute 204 is offered on wall, slide bar is provided on the tensile resistance rod 24, and the slide bar is slidably disposed on the sliding slot
Interior, the axial line of the guide chute 204 from the drive rod 20 extends outwardly upwards.
It exerts a force for convenience to drive rod 20, forces drive rod 20 to move down, offered only on the inner sidewall of the shell 10
Dynamic sliding slot 102, the bottom of the drive rod 20 are provided with stop slider 201, and the stop slider 201 can slide up and down to setting
In the stop sliding slot 102；The upper end of the drive rod 20 can be rotatably set spill spin block 21, as shown in figure 4, connecting
The upper end of block is provided with connection sliding block 2021, and connection sliding slot is offered on spill spin block 21, and connection sliding block 2021 is rotationally set
Set connection sliding slot in, external screw thread is offered on the spill spin block 21, offered on the inner sidewall of the containing cavities 101 with it is described
The internal screw thread that external screw thread matches drives the drive rod 20 to move up and down when the spill spin block 21 rotates.Link block 202
Upper end, which offers, to be used for and driving device, such as the interior hexagonal groove that hex bolts matches, passes through driving device or tool drives
Link block 202 rotates, and link block 202 moves down under the action of being threadedly engaged and then link block 202 is driven to move down, and drives and drives
Lever 20 moves down, due to the presence of stop slider 201, when link block 202 rotates, it is ensured that drive rod 20 does not occur to turn
It is dynamic.
Soil makes the slide bar on tensile resistance rod 24 that drive rod 20 be forced to move up to the reaction force of tensile resistance rod 24 in order to prevent,
Further include spring 23 and locking rod 22, offer lock groove 121 on the inner sidewall of the turning end 12, the drive rod 20 it is upper
End has link block 202, and accommodating groove is offered on the link block 202, and the spring 23 and the locking rod 22 are located at described
In accommodating groove, described 23 one end of spring is connected in the accommodating groove, the other end is connected on the locking rod 22, the storage
The position of slot and the lock groove 121 is corresponding.When locking rod 22 moves lock groove 121 to end, locking rod 22 is in spring 23
Under the action of be extruded into lock groove 121, a part of locking rod 22 is located in accommodating groove at this time, another part is located at lock groove
In 121, thus can guarantee drive rod 20 will not because of soil reaction force and cause to move up, entire power grounding pile at this time
An organic whole is formed, is difficult to extract from soil.
Disclosed above is only several specific embodiments of the invention, and still, the embodiment of the present invention is not limited to this, is appointed
What what those skilled in the art can think variation should all fall into protection scope of the present invention.
