[0025] The present application discloses a method for casting an anti-displacement fixture for an underground grounding electrode, see Figure 1 , Figure 2 , including a fixed sleeve 1 and an adjustable support member 2. The fixed sleeve 1 is sleeved on the periphery of the metal conductor, and a plurality of adjustable support members 2 for supporting the metal conductor are arranged on the upper part thereof. The cooperation between the fixed sleeve 1 and the adjustable support member 2 enables the metal conductor to be firmly fixed in the middle of the fixed sleeve 1.

[0032] In some embodiments, the extension lines of the plurality of adjustable supporting members 2 pass through the axis of the fixed sleeve 1 .
[0033] [Example 1]
[0034] The embodiment of the present application provides a balanced fixed conductor technology during the installation of buried poles, and the specific contents are as follows: When making a grounding pole, the grounding pole (metal conductor) needs to be firmly fixed in the middle of the resistance reducing agent and evenly wrapped to increase the contact area with the original soil and improve the conductivity of the grounding pole and the soil. The metal iron design is generally a 2.5m long 50mm angle steel or steel pipe and other conductors. It is necessary to fix it in a position and be evenly wrapped with the blended resistance reducing agent. During the pouring and pouring process, the external force causes the grounding pole to be fixed at only one point, and it moves under the continuous squeezing of the resistance reducing agent, which affects the installation quality and installation progress, increases labor costs and brings economic losses. Therefore, a fixed sleeve 1 with a stabilizing function is designed. The upper part of the fixed sleeve 1 is evenly provided with round holes 101. The adjustable support member 2 is inserted into the round holes 101. A gripper 201 with an arc is provided at one end of the adjustable support member 2, and the other end is connected to the outside of the fixed sleeve 1. An external thread is provided at one end of the external end of the fixed sleeve 1. When the adjustable support member 2 is installed, the locking ring 3 is clamped on the outside and the locking nut 4 is used to cooperate with the external thread to tighten and lock the adjustable support member 2, which can be locked to any position; due to the cooperation of the evenly distributed adjustable gripper 201, the metal conductor is firmly fixed in the middle of the fixed sleeve 1. When the resistance reducing agent is added to the fixed sleeve 1, the filling operation without too much intervention will make the conductor molded in the middle position of the resistance reducing agent, reducing the time spent on manual adjustment and the adjustment is not concentrated. Ensure the continuity of work, and easy installation and disassembly, greatly improve work efficiency, reduce production costs and rework production costs caused by failure.
[0035] At present, the production of buried grounding electrodes requires repeated manual adjustments, and under the action of external forces, the grounding electrodes are constantly displaced and cannot be placed in the center. After using this design, the grounding electrode backfill resistance reduction agent will be formed in one step; the metal conductor is fixed under the action of the fixture and evenly wrapped, maximizing contact with the original soil, increasing conductivity, improving project quality and reducing rework; extending service life; promoting construction progress, reducing personnel input, and realizing continuous mechanical operation; reducing construction material waste and improving economic benefits.
[0036] [Example 2]
[0037] A buried grounding electrode casting anti-displacement fixture comprises a fixed sleeve 1, the upper part of the fixed sleeve 1 is evenly provided with round holes 101, an adjustable support member 2 is inserted into the round hole 101, a gripper 201 with an arc is provided at one end of the adjustable support member 2, and the other end is connected to the outside of the fixed sleeve 1, and an external thread is provided at one end of the fixed sleeve 1. When the adjustable support member 2 is installed, the adjustable support member 2 is clamped by a locking ring 3 on the outside and is fastened and locked by a locking nut 4 and the external thread, and can be locked to any position; due to the cooperation of the evenly distributed adjustable gripper 201, the metal conductor is firmly fixed in the middle of the fixed sleeve 1, and when a resistance reducing agent is added to the fixed sleeve 1, the filling operation without too much intervention will make the conductor molded in the middle position of the resistance reducing agent, reducing the time consumption and the non-concentrated adjustment during manual adjustment. Ensure the continuity of work, and easy installation and disassembly, greatly improve work efficiency, reduce production costs and rework production costs caused by failure.
[0038] There are three circular holes 101 on the fixed sleeve 1. Since the circular holes 101 have a certain length, the adjustable support member 2 can be better fixed inside the fixed sleeve 1 without displacement. Therefore, the circular holes 101 are provided with annular protrusions on the outer wall of the fixed sleeve 1 for extending the circular holes 101. The three circular holes 101 have a certain length, and when the locking ring 3 is squeezed and fixed, no deflection and displacement will occur. The three grippers 201 can cooperate to fix the conductors of different shapes in the middle well, can withstand large external forces, and will not deviate and affect the quality when the resistance reducing agent is poured in.
[0039] At present, the production of buried grounding electrodes requires repeated manual adjustments, and under the action of external forces, the grounding electrodes are constantly displaced and cannot be placed in the center. After using this design, the grounding electrode backfill resistance reduction agent will be formed in one step; the metal conductor is fixed under the action of the fixture and evenly wrapped, maximizing contact with the original soil, increasing conductivity, improving project quality and reducing rework; extending service life; promoting construction progress, reducing personnel input, and realizing continuous mechanical operation; reducing construction material waste and improving economic benefits.

It ensures the continuity of work and is easy to install and disassemble, which greatly improves work efficiency, reduces production costs and rework costs caused by failures.
[0042] The locking ring 3 is an open snap ring, which is clamped to the end of the adjustable support member 2 extending outside the fixed sleeve 1 when in use, with one side of the locking ring 3 in contact with the outer wall of the fixed sleeve 1, and the other side in contact with the locking nut 4.
