[0021] The following is combined with Figure 1-4 To further explain this application in detail,

[0022] An embodiment of the present application discloses an electrical test grounding device, including a support, a grounding electrode 6 and an isolation box 9, the support is composed of an upper plate 1 and a lower plate 2 connected by two support rods 3, a plug sleeve 4 is provided at the central connection between the upper plate 1 and the lower plate 2, and a lifting ring 5 is provided on the upper plate 1; the grounding electrode 6 is inserted into the plug sleeve 4 through a plug block 7 fixed on its outer side surface, and the plug block 7 and the plug sleeve 4 are fixed together by bolts 8; the isolation box 9 is installed and fixed on the top of the upper plate 1, and the upper cover of the isolation box 9 is connected to a pedal 10.

[0023] When the electrical test grounding device is used, the grounding electrode 6 is inserted into the soil, and the pedal 10 is stepped on the isolation box 9 and the support, so that the grounding electrode 6 is stably and firmly stepped into the soil. After the electrical test is completed, the grounding electrode 6 is pulled up from the soil layer by pulling up the lifting ring 5;

[0024] By stepping on the pedal 10, the grounding electrode 6 is firmly and securely inserted into the soil, ensuring a good grounding effect. The structural design of the plug block 7 and the socket sleeve 4 and the fixation of the bolt 8 ensure a firm connection between the grounding electrode 6 and the support. The design of the pedal 10 allows the operator to easily insert the grounding electrode 6 into the soil, and the setting of the lifting ring 5 facilitates the lifting of the grounding electrode 6 out of the soil after the test. The presence of the isolation box 9 can provide additional safety protection to avoid accidental electric shock and other dangerous situations during the test. The setting of the pedal 10 can also reduce accidental injuries caused by careless operation. The design with simple structure and clear functions is conducive to improving the durability and service life of the device and reducing the probability of possible failures.

[0025] Two ground-inserting rods 11 are fixedly provided on both sides of the bottom of the lower plate 2 .

[0026] The ground rod 11 can play a role of fixed support in the soil and enhance the stability of the support on the ground. Especially when the soil is soft or uneven, the ground rod 11 can prevent the support from tilting or moving due to weight or external force. The provision of the ground rod 11 can increase the grounding area and improve the grounding effect. By fixing the lower plate 2 to the ground by the ground rod 11, it can be ensured that the grounding electrode 6 is in full contact with the soil, thereby effectively eliminating the residual charge in the electrical equipment. The ground rod 11 is fixed to the ground to prevent the support from shifting due to external vibration or other factors during use, thereby maintaining the stability and safety of the device.

When the user steps on it, the lock buckle 17 can lock the pedal 10 to ensure that it is in the correct position, thereby providing a safe operating environment. The design of the hinge shaft 16 and the lock buckle 17 allows the pedal 10 to be easily opened from the isolation box 9, so that when maintenance or replacement of the connecting line is required, the operation process can be simplified and the maintenance efficiency can be improved.

[0031] Vertical plates 19 are provided on both sides of the upper plate 1 , and the two vertical plates 19 are rotatably connected to the rotating shafts 20 fixedly connected to the lifting rings 5 ​​.

[0032] The design of the rotating connection allows the lifting ring 5 to rotate freely, making it easy for the operator to lift and put down the grounding electrode 6, thereby improving the convenience and flexibility of the operation.

[0033] The electrical test grounding device has a simple structure, clear functions, easy operation and maintenance, and increased service life. The setting of the ground rod 11 enhances the stability of the support and the grounding effect. The design of the isolation box 9 provides additional safety protection to avoid dangerous situations such as accidental electric shock during the test. The connection between the grounding electrode 6 and the grounding wire is firm and stable, ensuring a good grounding effect.
