[0002] Oil storage tanks, referred to as oil tanks or storage tanks, are large containers with regular shapes used to store oil products. They can be divided into metal oil tanks and non-metal oil tanks according to different construction materials. Most metal oil tanks are steel oil tanks, which are commonly used in oil depots; non-metal oil tanks are also called "earth oil tanks". Due to poor safety risks, they have been gradually eliminated since the 1990s.

[0003] After being used for a long time, the oil storage tank will have wax scraping phenomenon, so it is necessary to use a wax scraping device to scrape the wax on the inner wall of the oil storage tank. However, the existing wax scraping device for the tank is not convenient to move after being fixed on the oil storage tank. Therefore, when scraping the wax on the inner wall of the oil storage tank, it is necessary to disassemble and install the wax scraping device many times, which is time-consuming and labor-intensive.
