The utility model relates to the technical field of geological exploration, and discloses a geological exploration anti-collapse device which comprises a first bottom stand column, a second bottom stand column is arranged on the right side of the first bottom stand column, and a third bottom stand column and a fourth bottom stand column are arranged in front of the second bottom stand column and the first bottom stand column respectively. First inner baffles are installed on the inner walls of the first bottom stand column and the second bottom stand column, second inner baffles are installed on the inner walls of the second bottom stand column and the third bottom stand column, and third inner baffles are installed on the inner walls of the third bottom stand column and the fourth bottom stand column. When soil makes contact with an outer baffle, the outer baffle and a second fixing block can move towards the middle, at the moment, a movable rod moves on a limiting rod, the movable rod extrudes a buffer spring, the impact force of the soil is buffered through the elastic force of the buffer spring, and then the problem that certain impact force is generated when the soil collapses is solved; and the impact force can directly hit the geological exploration anti-collapse device, and seriously, the geological exploration anti-collapse device can be damaged.

This utility model discloses a tank surface spraying device, specifically including a spraying mechanism. The spraying mechanism has the advantages of being suitable for most oil tank specifications and allowing for paint recycling. It has two support mechanisms, each with a three-jaw clamp and a hydraulic telescopic rod, allowing for adjustable spacing. Each support mechanism has two additional support mechanisms for fixing both ends of the oil tank, and the oil tank can rotate relative to the support mechanisms. It can replace manual labor in spraying the surface of oil tanks. It also includes a recycling mechanism to filter and recycle excess paint, improving work efficiency while mitigating the health risks to spraying personnel. It is applicable to various sizes of oil tanks.
