Furthermore, the terms "1 #", "2 #", "3 #" and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "1 #", "2 #", "3 #", etc. may explicitly or implicitly include one or more of the features.

Example 1:

as shown in fig. 1, the embodiment of the present invention provides a grounding device for high-density electrical method, which includes a tank body 2 with a cavity and a base installed at the bottom of the tank body 2. The bottom of the tank body 2 is provided with an internal thread, the top of the base is provided with an external thread, and the tank body 2 and the base are connected through the thread to form a detachable structure.

The can body 2 is made of a transparent material, specifically, a transparent plastic, or a glass.

As shown in fig. 1 and 3, an electrode socket 7 is arranged at the center of the top of the can body 2, and a waterproof rubber plug 1 with a through hole is arranged in the electrode socket 7. The top of the tank body 2 is also provided with a water filling port 5. The electrode socket 7 and the water filling port 5 are both higher than the upper surface of the tank body 2, and form a structure similar to a bottle mouth. The outside of the electrode socket 7 and the water filling port 5 are provided with external threads, which can be sealed with a cap when the device is not in use.

Specifically, in order to facilitate water injection, the water injection port 5 is arranged at the edge of the top of the tank body, the diameter of the water injection port is larger than that of the electrode socket 7, and the height of the water injection port 5 is also larger than that of the electrode socket 7.

Two half-moon-shaped bag-shaped thin sheets are arranged inside the waterproof rubber plug 1 to form a structure similar to a vein valve, so that the waterproof rubber plug can still have a good waterproof effect after an electrode is inserted, and the internal sealing of the tank body 2 is kept. The internal diameter of waterproof rubber buffer 1 slightly is less than the electrode diameter, and when the electrode inserted waterproof rubber buffer 1, waterproof rubber buffer 1 can block the electrode and have certain sealed effect. When the earthing device accident emptys, waterproof rubber buffer 1 can prevent effectively that the inside liquid of jar body 2 from spilling.
