Land gradient measuring device for engineering exploration

Abstract

The invention discloses a land gradient measuring device for engineering exploration. The land gradient measuring device comprises a base, a box body, a gradient measurement swing piece, a vertical fixed pointer, a swing limiting piece and a telescopic inserting positioning rod; the bottom end of the box body is fixedly connected with the top end of the base, a containing cavity is formed in the box body, and an observation window is formed in the box body; the gradient measurement swing piece is rotatably arranged on the cavity wall of the containing cavity, gradient scales and an arc-shapedinserting positioning groove are formed in the gradient measurement swing piece, and an arc-shaped swing limiting groove is formed in the cavity wall of the rear side of the containing cavity; the vertical fixed pointer is fixedly connected with the rear side cavity wall of the containing cavity, and the pointer end of the vertical fixed pointer points to the gradient scales; the swing limiting piece is fixedly connected with the bottom end of the slope measuring swing piece; the bottom end of the swing limiting piece is in rolling contact with the arc-shaped swing limiting groove; and the telescopic inserting positioning rod is arranged on the rear side wall of the box body in a penetrating manner and is fixedly inserted into the arc-shaped inserting positioning groove. According to the device, the swing time of the slope measurement swing piece can be shortened, the slope measurement swing piece can be quickly stabilized and can be quickly positioned and fixed, so that quick measurement is realized, and the measurement efficiency is high.

Description

technical field [0001] The invention relates to the technical field of land surveying, in particular to a land slope measuring device for engineering exploration. Background technique [0002] Land is an important material basis for human survival and development. With the growth of population, land has brought greater pressure on food production, resource pressure and ecological environment pressure, and the contradiction between man and land has become increasingly prominent. Land engineering not only plays an important role in protecting the quantity and quality of cultivated land, improving crop yields, and ensuring food security, but also an important means to expand human living space and improve human living environment. [0003] In engineering exploration, it is necessary to use a slope measuring device to measure the slope of the land. However, there are still some problems in the existing slope measuring device. For example, the patent No. is CN208902102U, and the...

Problems solved by technology

However, there are still some problems in the existing slope measuring device. For example, the patent No. is CN208902102U, and the name is called a slope measuring device for land engineering. The motor is reversed to put down the conical block for use. The operation process is cumbersome, and when measuring the slope, the conical block continues to swing for a certain period of time, and the data can only be collected after stabilization, making the measurement efficiency low. And it needs a power supply to measure, so the applicability is poor
