Problems solved by technology
[0007] 1) There are copper wires (belts), copper clad steel (including electroplated copper, etc., continuous casting copper) lightning protection grounding wires. Although the corrosion resistance performance has been improved for general medium soil environments, it still cannot meet the requirements of certain specific organic media. Corrosive environment, because once the product is formed, it cannot change its surface corrosion resistance to specific corrosive media, and a large amount of copper is buried in the soil, if it does not match the background metal content of the original soil environment, the soil environment of the area will be used polluted
[0008] 2) There are galvanized steel materials supplemented by a large amount of resistance reducing agent to reduce the grounding resistance, but in the construction under the complex climate environment (alpine, severe cold, etc.), it is basically impossible to meet the construction requirements, and the reliability of the electric welding joint At the same time, the resistance reducing agent may also cause corrosion to the grounding steel material, and the welding point cannot be guaranteed against corrosion.
The method described in ZL03214327.3 only uses a bentonite drag-reducing agent, which can only equivalently increase the cross-sectional area of the grounding body, and cannot change the various drag-reducing agents that cannot be completely and fully wrapped due to harsh construction conditions. For the grounding body, it is unrealistic to design various complex control methods for the construction process because the grounding body needs to be completely and fully wrapped. This has been a consensus in the industry
At the same time, the resistance reducing agent should be formed into thick flocculation on site (the manual process cannot guarantee the uniform coordination of various components), and the resistance reducing agent and the grounding body are in contact with metal and non-metal, and are a combination of solid and liquid phases. It has always been a big unsolvable problem in the field of grounding
[0009] 3) Some grounding modules or ionic grounding bodies are used. These products are produced by changing the resistance reducing agent. Not only are the prices high, but also the grounding body is developed in depth, and the construction cost is greatly increased.
In addition, the stability and reliability of the contacts at the connection point are limited by the quality of the later construction conditions, and the stability of the electrical connection cannot be guaranteed from the source
[0011] 5) Common grounding electrodes are installed underground without necessary anti-theft measures, so that they are buried in remote areas without anti-theft measures, and are easy to be stolen, resulting in more serious consequences

The invention discloses a scenic spot equipment grounding device, which comprises a plurality of grounding units and a grounding wire. Each grounding unit comprises a connection rod, a wear-resisting head arranged at the front end of the connection rod and movable driving heads arranged at the upper portion of the connection rod. The connection rod is internally provided with a blind hole. The side wall of the blind hole is provided with a plurality of micro through holes. The inner wall of the blind hole is provided with a waterproof film layer cooperated with the micro through holes. The waterproof film layer is internally provided with conductive liquid. The outer surface of the connection rod is provided with an external thread. The blind hole is internally provided with conductive liquid. At the upper liquid surface of the conductive liquid, a floating plug falls down due to small buoyancy; then, the conductive liquid seeps from a gap between the floating plug and a tapered hole; with continuous seeping, contact conductivity between the connection rod and the soil is not reduced, and a slow-release effect can be obtained; and the grounding device is worthy of application and promotion.
Description
technical field [0001] The invention belongs to the technical field of scenic spot safety device protection, and in particular relates to a scenic spot equipment ground connection device. Background technique [0002] Although the proportion of the entire investment of the grounding device in the scenic spot is very small, the accidents caused by it are really amazing. For scenic spots in the wilderness, because there are no large buildings to block them, the amusement equipment and personnel in the scenic spot are very expensive. Exposure to the sky adds a layer of safety hazards when people face sudden strong convective weather. Therefore, ground guides are installed in each scenic spot to ensure electrical conductivity and avoid damage to tourists and amusement facilities. [0003] In CN 203149339 U, a remote-controlled electronic camera lightning protection controller is disclosed. The single-chip microcomputer in the microcontroller unit is externally connected with an ...
