26 results about "Sandpit" patented technology

A sandpit (most Commonwealth countries) or sandbox (US/Canada) is a low, wide container or shallow depression filled with soft (beach) sand in which children can play. Sharp sand (as used in the building industry) is not suitable for such use. Many homeowners with children build sandpits in their backyards because, unlike most playground equipment, they can easily and cheaply be constructed. A "sandpit" or "sandbox" may also denote an open pit sand mine.

A smart soil and water conservation device

This utility model relates to the field of ecological soil and water conservation technology and discloses an intelligent soil and water conservation device, including a slope plate, plants, and a circulating pump. The slope plate has a sand collection pool and a sand fixation trough on both sides of its inner cavity. It also includes a first inclined filter plate, which is fixedly installed on the inner wall of the sand collection pool. This utility model can filter the sand in the sand collection pool in layers through the first, second, and third inclined filter plates. Large sand particles can pass through the inclined filter plates of different diameters in sequence and enter the step plate through the filter plates with matching filter holes. This allows sand particles of different sizes in the soil erosion to be separated and enter the space formed by the adjacent filter plates, step plates, and inclined baffles. The roots of the plants on the outside of the inclined baffles can further fix the sand in the space. In this way, different sand particles can be filtered in layers, and the smaller, heavier sand particles can settle to the bottom of the inner cavity of the slope plate.
