[0030] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The embodiment of the present application provides an indication centering device for underground measurement, comprising an anvil plate assembly 1 and a laser centering assembly 2.

[0031] The anvil plate assembly 1 comprises an anvil plate shell 3, the inside of the anvil plate shell 3 forms an accommodating space, the upper part of the accommodating space is provided with a first light triangular indication area 4, one side of the accommodating space is provided with a second light triangular indication area 5, and the other side of the accommodating space is provided with a third light triangular indication area 6; the anvil plate shell 3 is further provided with a prism placing notch 7, and the first light triangular indication area 4, the second light triangular indication area 5 and the third light triangular indication area 6 all point to the prism placing notch 7.

[0032] The laser centering assembly 2 comprises a laser centering base 8, the lower part of the laser centering base 8 is provided with a docking card slot 9, and the laser centering assembly 2 is connected with the anvil plate assembly 1 through the docking card slot 9; the top of the laser centering base 8 is provided with a laser fixing slot 10, the bottom of the laser fixing slot 10 is provided with a laser lower alignment hole 11, and the laser fixing slot 10 is configured with a laser body 12.

[0033] In this embodiment, the edge of the first light triangular indication area 4 is provided with the first light source 13, and the other edge of the first light triangular indication area 4 is provided with the first light blocking layer 14; the edge of the second light triangular indication area 5 is provided with the second light source 15, and the other edge of the second light triangular indication area 5 is provided with the second light blocking layer 16; the edge of the third light triangular indication area 6 is provided with the third light source 17, and the other edge of the third light triangular indication area 6 is provided with the third light blocking layer 18. The interior of the first light triangular indication area 4 is provided with the first light guide fiber group 19, and the inner side of the first light triangular indication area 4 is provided with the first light reflecting layer 20; the interior of the second light triangular indication area 5 is provided with the second light guide fiber group 21, and the inner side of the second light triangular indication area 5 is provided with the second light reflecting layer 22; the interior of the third light triangular indication area 6 is provided with the third light guide fiber group 23, and the inner side of the third light triangular indication area 6 is provided with the third light reflecting layer 24.

[0034] Specifically, the first light source 13 emits light to the first light triangular indication area 4, the light is emitted to the first light guide fiber group 19 in the interior of the first light triangular indication area 4, and the light is refracted and reflected in the first light guide fiber group 19 under the action of the first light reflecting layer 20 and the first light blocking layer 14, so that the first light triangular indication area 4 emits soft light from the outside. Similarly, the second light source 15 emits light to the second light triangular indication area 5, the light is emitted to the second light guide fiber group 21 in the interior of the second light triangular indication area 5, and the light is refracted and reflected in the second light guide fiber group 21 under the action of the second light reflecting layer 22 and the second light blocking layer 16, so that the second light triangular indication area 5 emits soft light from the outside. The third light source 17 emits light to the third light triangular indication area 6, the light is emitted to the third light guide fiber group 23 in the interior of the third light triangular indication area 6, and the light is refracted and reflected in the third light guide fiber group 23 under the action of the third light reflecting layer 24 and the third light blocking layer 18, so that the third light triangular indication area 6 emits soft light from the outside.

[0035] In subsequent measurement work, three triangular light-emitting areas can be formed on the anvil shell 3, i.e. the first light triangular indication area 4, the second light triangular indication area 5, and the third light triangular indication area 6. Since the first light triangular indication area 4, the second light triangular indication area 5, and the third light triangular indication area 6 all point to the prism placing gap 7, the measurer can accurately locate the prism position through the emitted soft light, which is convenient for aligning the prism in the prism placing gap 7 in the measurement process. The soft light generated by the light-emitting area is blocked by the anvil shell 3 and the light guide fiber, so it does not affect the operation of the measurer and does not interfere with the measurement result of the instrument, which can ensure the measurement accuracy. The prism can be quickly identified and aligned, so that convenient and fast measurement work is realized.

[0036] The light guide fibers in the first light guide fiber group 19, the second light guide fiber group 21 and the third light guide fiber group 23 utilize the principle of refraction and total reflection of light, and when the incidence angle is less than the critical angle, the light enters the surrounding air from the light guide fiber, at which time the refraction and reflection phenomena occur simultaneously. Part of the light is refracted into the air, and the other part of the light is reflected back into the light guide fiber and continues to propagate in the direction of the light guide fiber, and then the light refracted out of the light guide fiber illuminates the first light triangular indication area 4, the second light triangular indication area 5 and the third light triangular indication area 6 on the chopping board shell 3.

In addition, an observation port 31 is formed on the front side of the laser centering base 8.

[0038] Specifically, the first laser emission head 25 on the laser body 12 can emit a laser line downward, thereby facilitating the calibration of the laser centering assembly 2 to coincide with the central vertical axis of the instrument to be assembled. At this time, the observation port 31 can be observed to ensure that the laser body 12 is on the central vertical axis of the instrument to be assembled. Meanwhile, the second laser emission head 26 can emit a laser line upward, thereby indicating the central upward projection point of the instrument.

[0039] In the embodiment, the side of the laser centering base 8 is connected with a transverse level bubble 27 and a longitudinal level bubble 28. Through the leveling operation of the transverse level bubble 27 and the longitudinal level bubble 28, it can be ensured that the laser centering base 8 as a whole is in a horizontal position, thereby ensuring the accuracy of the instrument centering operation.

The laser adjustment shaft 30 is screwed into the laser centering base 8, and the end of the laser adjustment shaft 30 extends into the laser fixing groove 10 to adjust the position of the laser body 12.

[0041] Specifically, the laser adjustment shaft 30 can be rotated by the fine adjustment wheel 29, so that the end of the laser adjustment shaft 30 abuts against the laser body 12, thereby fine-tuning the position of the laser body 12 to ensure that the laser emitted by the first laser emission head 25 of the laser body 12 can pass through the laser lower hole 11.

The first rubber pad 32 and the second rubber pad 33 increase the firmness of the docking slot 9 and the assembled anvil assembly 1.

[0043] In a possible embodiment, the front side of the anvil shell 3 is covered with a diffusing coating / diffusing film. The diffusing coating / diffusing film reduces the intensity of the light by changing the propagation angle of the light passing through the coating / diffusing film, so that the light can illuminate the first light triangular indication area 4, the second light triangular indication area 5, and the third light triangular indication area 6 on the front side of the anvil shell 3, and the light of the first light triangular indication area 4, the second light triangular indication area 5, and the third light triangular indication area 6 is soft.

[0044] In a possible embodiment, the anvil assembly 1 and the laser centering assembly 2 are combined in the form of Figure 6 When the centering and leveling operation of the laser centering assembly 2 is completed, the laser emitted by the laser body 12 can indicate the upper point during the downhole centering operation, and this downhole centering method can help the downhole survey personnel to intuitively and quickly perform the related operation, reduce the difficulty of centering work, and effectively improve the efficiency and accuracy of the survey work.
