Welding a female end (9) of the regular hexagonal spiral bayonet at the center of a rocker (8), and sequentially welding and connecting a male regular hexagonal spiral bayonet (2), a drill body (6) and a drill bit (7) from top to bottom; the drill body (6) is of a hollow structure, the upper part of the drill body is provided with a water injection port (1), and the periphery of the drill body is perforated to form a water outlet hole (5); the spiral triangular steel strip (4) is welded on the drill body (6) from top to bottom (or from bottom to top) in a surrounding manner to form a precession type drill body, and the uppermost end of the drill body (6) is welded with a wiring terminal (3).
The rocker (8) and the main body part of the grounding electrode are designed into a split structure, so that the transportation and carrying are convenient.
The drill body (6) is provided with a water outlet, so that the current conduction and the voltage test can be further improved.
The utility model is matched with a main ground network test device for use, and comprises a test instrument (11), a power supply (10), a grounding wire (12), a voltage and current test wire (13), a tested grounding body connecting wire (14) and a grounding body (15). The testing instrument (11) is connected to a power supply (10), the testing instrument (11) is connected with the grounding body (15) through a tested grounding body connecting wire (14), is grounded through a grounding wire (12), and is connected to the wiring terminal (3) of the drill body (6) through a current testing wire (13).
The test operation process of the utility model is as follows: firstly, a main body part of the portable screwing-in main earth screen test grounding electrode is forcibly inserted into a proper position, a regular hexagon spiral bayonet nut (9) of a rocker (8) is butted with a regular hexagon spiral bayonet male (2) of the main body part of the grounding electrode to be connected to the main body part of the grounding electrode, the portable screwing-in main earth screen test grounding electrode is forcibly and slowly screwed into soil to a proper position, and the rocker (8) is taken down.
The voltage and current testing wires (13) are respectively connected to the wiring terminal (3) of the grounding electrode and the testing instrument (11), and the testing instrument (11) is connected with the grounding body (15) through the grounding wire (12) and is reliably grounded; the test instrument (11) is connected to a power supply (10) by a power line.
After the installation is finished, the test is carried out according to a test method. If the output current is small, a proper amount of water can be injected into the water injection port (1) until the output current meets the test conditions.
The portable precession main ground grid test grounding electrode is small in size, light in self weight, convenient to carry and use, greatly improves test efficiency, improves test accuracy, reduces test time, and saves test manpower and material cost.
The utility model is characterized in that: (1) the difficulty of finding the grounding electrode on the actual construction site is solved. Due to the fact that a construction site has large uncertain factors, a test grounding electrode with a proper length is difficult to find for a tester to use. The utility model solves the problem that the grounding pile is difficult to find in the ideal test of the construction site. The utility model has small volume, can be transported to a construction site, can be carried by a single person, can be operated by a single person and is convenient to use. (2) The problems of labor consumption and difficulty in carrying in the traditional method are solved. The traditional test method is to carry a sledge hammer, a plurality of groups of angle steels and the like by a plurality of people for field test, and in the test process, if the grounding electrode is not matched or the test can not be carried out continuously, the grounding electrode can not be pulled out, and a new grounding electrode needs to be driven into the ground again by changing the place, so that a plurality of groups of self-made grounding electrodes need to be carried by a plurality of people. The utility model can be screwed in and out, so that the test (3) can be completed only by carrying a group of grounding electrodes without carrying a sledge hammer, and the problem of non-ideal test process is solved. In the traditional test process, when testing, the situation that the test current cannot be increased due to too dry soil is often encountered, so that the test result is not ideal. The utility model designs the water outlet hole, can be normally used in a dry soil section, and does not need to change the position. Therefore, the waste of materials can be reduced, and the environment is protected.
The portable precession main ground grid test grounding electrode provided by the utility model can be used under a complicated geographical condition, the difficulty of finding and manufacturing the grounding electrode on site is avoided, the load bearing work of testers is greatly reduced, the defect that the test cannot be carried out due to dry soil is overcome, and the test accuracy and the test efficiency are improved.
