Description

The utility model relates to devices for measuring coordinates. It can be used, for example, during excavations, to measure the position of a find in space.

From the state of the art there is known a means of light indication for determining the position on the ground of a point taken out into nature [patent for utility model RU 148070 U1, application No. 2014114023/28 dated 04/09/2014, publ.: 11/27/2014 in Bull. No. 33], in which the indication means for determining the position of the point to be staked out according to the signal generated by the computing unit, which determines the position of the point to be staked out relative to the position of the point under study, is made in the form of a light indication means.

The disadvantage of this device is that when using a light indication method, which, if the surface area is uneven, may not provide information about the coordinates, incomplete and unreliable data is obtained.

The closest to the claimed technical solution is “Device for determining the transverse profile of a soil ridge” [patent RU 150391 U1, application No. 2014130347/28 from 07/22/2014, publ.: 02/20/2015 in Bulletin. No. 5], including a panel with lines in the vertical and horizontal directions and a scale. The panel is made of transparent material. In the upper and side parts of the panel, vertical and horizontal scales with a division value of at least 1 mm are installed at an angle of 90 °.

The disadvantages of the prototype are that measurements are made relative to two axes, which allows only two coordinates to be found and leads to the lack of reliable information about the position of points in space along one of the three coordinate axes.

The technical result of the proposed utility model is the ability to carry out measurements in 3 coordinates while reducing the measurement error.

The technical result is achieved by the fact that the mechanical indication device for determining the position of a point on the ground contains a measuring rod and a rail, with measuring scales applied to them, while the measuring rod is fixed to a carriage located on the rail, with a screw connection at an angle of 90° relative to the rail, while the carriage is fixed on the rail with two thumbscrews, and the rail is equipped with mounting pegs located at the ends of the rails.

Figures 1 and 2 show the design of the claimed technical solution, where 1 is a measuring rod, 2 is a rail, 3 is a carriage, 4 is a wing screw, 5 is a mounting peg. In this case, figure 1 shows a side view, with the measuring rod in a vertical position, figure 2 shows a top view, with the measuring rod in a horizontal position.

Carriage 3 allows you to tilt the measuring rod perpendicular to the horizontal surface of the rail at an angle of 90°. In addition, carriage 3 with measuring rod 1 can be moved along rail 2 and fixed in the desired position using wing screws 4.

All parts of the utility model, indicated in figures 1 and 2 by positions 1-5, can be made of various materials (metal, plastic, wood, etc.).

The device works as follows: rail 2 is installed inside at the edge of the excavation, secured to the ground using fastening pegs 5. Carriage 3 is moved along rail 2 to the desired position, secured in a given position using wing screws 4 and using measuring rod 1 and rails 2 measure coordinates on the surface of the earth. In the same way, the coordinates of the next fossil are found. Having measured two coordinates of the fossil, raise the measuring rod 1 to a vertical position, secure the carriage 3 using thumbscrews 4 in a given position on the rail 2 and measure the height of the layers of the earth.

Advantage of a utility model:

The use of carriage 3 allows you to move measuring rod 1 relative to rail 2, which minimizes the error in the coordinates of the find by maintaining 90° between rail 2 and measuring rod 1.

The ability to rotate the measuring rod 1 from a horizontal to a vertical position allows you to determine the height of the layers of the earth, and accordingly obtain data on the location of the fossil in a three-coordinate plane.

Thus, a mechanical indication device for determining the position of a point on the ground provides an accurate measurement of the coordinates of the find, using the movement of the measuring rod horizontally, vertically and the height of the ground layer.

The claimed technical solution increases the reliability of measurements.
