Abstract

The utility model discloses a gradient measurement instrument which comprises a board, an iron sheet, two bar magnets, a set square, a protractor, a needle, a heavy punch and a wire, wherein the board is horizontally placed on a table, the iron sheet is fixedly tiled on the board, the set square is vertically placed on the iron sheet surface, the short right-angle side of the set square is in contact with the iron sheet surface, the two bar magnets clamp the set square and are adsorbed on the iron sheet, the protractor and the set square are placed in parallel, the protractor is perpendicular to the long right-angle side of the set square, the needle is vertically fixed at the center of the semicircle of the protractor, one end of the wire is tied to a needle eye, and the other end thereof is tied to the heavy punch. According to the gradient measurement instrument, the operation is easy, the structure is simple, relatively accurate gradient value can be measured by utilizing simple physical knowledge; in addition, the gradient measurement instrument can be dismantled when not in use, so that the occupied area is reduced, and the storage is facilitated, and when in use, the gradient measurement instrument can be quickly assembled, and zero setting is not needed.

Description

A kind of instrument of measuring the gradient

Technical field

The utility model relates to a kind of technical field of surveying instrument, especially a kind of easy gradiometer.

Background technology

Usually, people are when measuring the gradient, mostly be to complete with ruler, spirit-leveling instrument etc., the data that this method obtains must just can obtain value of slope through calculating, and data-generating process is comparatively complicated, in addition, carry out in the process of slope measuring, some needs are measured the length of some region etc., thereby will carry more instrument, to the gauger, cause inconvenience in the majority.

The utility model content

The utility model provides a kind of instrument of measuring the gradient, and it is simple to operate, simple in structure, reading has been accomplished again economical and practical, easy to carry intuitively simultaneously and measured value is also very accurate.

Technical solutions of the utility model

A kind of instrument of measuring the gradient, include plank, iron sheet, two of bar magnets, set square, protractor, pin, weight, line,: described plank horizontal positioned is on the table, iron sheet fixedly is tiled on plank, set square vertically is placed on the iron sheet face, short right-angle side contacts with the iron sheet face, two blocks of bar magnets are clamped set square and inhale on iron sheet, protractor placement parallel with set square and protractor are perpendicular to the long right-angle side of set square, pin is vertically fixed on the home position of protractor semicircle, one, line ties up on pinprick, and there is weight in other end system.

Advantage of the present utility model

The utility model is simple to operate, simple in structure, has utilized simple physical knowledge just can measure relatively accurate value of slope, and the used time can not take it apart, thereby reducing institute takes up space, be convenient to deposit, again can be rapidly with its assembling when using, and need not zeroing.

Description of drawings

Fig. 1 is stereographic map of the present utility model.

Embodiment

shown in accompanying drawing 1, a kind of instrument of measuring the gradient, include plank 1, iron sheet 2, two 3 of bar magnets, set square 4, protractor 5, pin 6, weight 7, line 8, plank 1 horizontal positioned on the table, iron sheet 2 fixedly is tiled on plank 1, set square 4 vertically is placed on iron sheet face 2, short right-angle side contacts with 2, iron sheet, two blocks of bar magnets 3 are clamped set square 4 and inhale on iron sheet 2, protractor 5 and the parallel placement of set square 4 and protractor 5 are perpendicular to the long right-angle side of set square 4, pin 6 is vertically fixed on the home position of protractor 5 semicircles, 8 one, line ties up on pinprick, there is weight 7 in other end system, only need during measurement the plank of this device 1 is attached on required measurement domatic, the number of degrees of the protractor 5 at vertical and protractor 5 observation line 8 places of sight line just can obtain the numerical value of the gradient.

Claims

1. instrument of measuring the gradient, include plank, iron sheet, two of bar magnets, set square, protractor, pin, weight, line, it is characterized in that: described plank horizontal positioned on the table, iron sheet fixedly is tiled on plank, set square vertically is placed on the iron sheet face, short right-angle side contacts with the iron sheet face, two blocks of bar magnets are clamped set square and inhale on iron sheet, protractor placement parallel with set square and protractor are perpendicular to the long right-angle side of set square, pin is vertically fixed on the home position of protractor semicircle, one, line ties up on pinprick, there is weight in other end system.
