Problems solved by technology

When using the geological compass to measure the occurrence of the linear exposed structural surface and the structure surface with a gentle dip angle on the roof of the cavern, there are the following problems: (1) For the linear exposed structural surface, due to the small exposed surface, the cover back of the geological compass or The straight edge of the chassis cannot fit closely with the limited exposed interface, which makes it difficult to measure the occurrence of the structural surface, res

Embodiment Construction

[0031] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0032] like image 3 As shown, a geological compass auxiliary device for measuring occurrence is characterized in that: the auxiliary device is composed of two rectangular hard flat plates (materials can be metal, plastic, etc.) of the same size through hinged connection, wherein the hinged shaft has a scale , can read the opening and closing angle of two hard plates. like Figure 4 , The hinged shaft has a scale from 0° to 180°, which can read the opening and closing angles of the hard flat plate A and B.

[0033] like Figure 5 , the method for measuring the shape of a linear exposed structural surface by using the au...

Abstract

The invention discloses an auxiliary device for measuring attitude of a geological compass and a measuring method, the device comprises a rectangular hard flat plate A and a rectangular hard flat plate B with the same size, the hard flat plate A and the hard flat plate B are hinged through a hinge rotating shaft, and the hinge rotating shaft is provided with angle scales for reading opening and closing angles of the hard flat plate A and the hard flat plate B. By means of the device, extending and external expanding of the structural plane can be achieved, indirect measurement is achieved, the problems that a compass cannot be attached and is large in measurement error due to the fact that the exposed interface of the linear exposed structural plane is small are solved, and the problems that when the cavern top gentle dip structural plane is measured, the compass opening and closing angle is small, sight is blocked, and reading cannot be achieved are solved. And the efficiency of attitude measurement and the accuracy of measurement results are improved.

Description

technical field [0001] The invention relates to the field of geological surveying, in particular to an auxiliary device and a measuring method for geological compass measuring occurrence. Background technique [0002] The geological compass is of great significance in geological work and is known as one of the three treasures of geologists. There are many styles of geological compass, but their principles and styles are basically the same. The circular basin-type geological compass commonly used by geologists is composed of a magnetic needle, a dial, an inclinometer, an aiming target plate (or an aiming pointer), and a level installed in a metal circular basin. Typical DQL-2A geological compass such as figure 1 and figure 2 shown. When using the geological compass to measure the occurrence of the linear exposed structural surface and the structure surface with a gentle dip angle on the roof of the cavern, there are the following problems: (1) For the linear exposed str...
