Description

Technical Field

[0001] The utility model relates to the technical field of measurement, in particular to a mine depth measuring device. Background Art

[0002] Mine caves, as underground or mountain spaces for mining or excavating materials, are the core places for mineral mining. Mine cave depth measurement occupies a pivotal position in mine operations. It is of great significance for ensuring mine safety, optimizing mining processes, accurately assessing resource reserves and quality, environmental monitoring, and emergency rescue.

[0003] In the field of mine surveying, existing technologies provide a variety of means, including traditional plumb bob method, high-precision total station measurement, advanced laser scanning technology and geophysical methods, among which the plumb bob method is widely used due to its simplicity and low cost. This method uses gravity to allow the plumb bob to fall freely to the bottom of the mine, and then indirectly determines the depth of the mine by measuring the length of the plumb rope.

[0004] However, the actual shape and size of a mine tunnel are often complex and variable due to different geological conditions and mining needs. During the excavation process, the mine tunnel may encounter different rock formations, geological structures or faults. These natural factors often force the mine tunnel to change the excavation direction and form a curve. In addition, the design of the mine tunnel will also be adjusted according to the specific distribution and direction of the ore body, which may also lead to the formation of a curve.

[0005] When it comes to measuring the depth of a curved mine tunnel, the traditional plumb line laying method is inadequate because it can only measure the vertical depth of the mine tunnel. In order to more accurately measure the depth of a curved mine tunnel, it is usually necessary to use advanced equipment such as laser scanners for auxiliary measurements. Although this comprehensive measurement method can provide more comprehensive data, the operation process is relatively cumbersome and has high requirements for equipment.

[0006] In order to cope with the complex and changeable environment and obstacles in the mine, self-driven measuring heads have appeared in the prior art. These measuring heads use the backjet of water or air to provide power, so that they can move autonomously in the mine. However, due to the complex structure of the mine, the uneven ground and the presence of various obstacles, the performance of these measuring heads in practical applications is not ideal and still needs further optimization and improvement. To this end, we propose a mine depth measurement device. Utility Model Content

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Embodiment 1:

[0030] See also Figure 1-5The utility model provides a technical solution: a mine depth measuring device, comprising a measuring tube 1, the measuring tube 1 is wound on a winding device, wherein the winding device is a prior art, comprising a driving motor and a reel driven by the driving motor, the rotation of the reel can make the measuring tube 1 reel and unwind, and the head end of the measuring tube 1 is connected to a high-pressure air pump, the end of the measuring tube 1 is connected to a measuring head 2, the measuring head 2 is hollow, a camera and a battery and some control terminals are installed in the measuring head 2, all of which are prior art and are not described here, and also includes an air box 3 fixedly arranged in the measuring head 2, a main nozzle 4 and a side nozzle 5 for driving the measuring head 2 to move and turn are provided on the outer side wall of the measuring head 2, an electromagnetic valve is provided at the side nozzle 5, a staff member can remotely control the electromagnetic valve to make the side nozzle 5 conduct with the air box 3, and then drive the measuring head 2 to turn, and a connecting mechanism 6 is also provided in the air box 3 to control the conduction between the main nozzle 4 and the air box 3, so that the main nozzle 4 located at the bottom of the measuring head 2 is opened.

[0031] An annular groove 61 is provided on the inner wall of the air box 3, and the connecting mechanism 6 includes a slider 62 slidably arranged in the annular groove 61, and a counterweight block 63 is arranged on the slider 62. When the posture of the measuring head 2 changes, the slider 62 is driven to move by the deadweight of the counterweight block 63, so that the counterweight block 63 can always move to the bottom of the annular groove 61. A plurality of groups of connecting holes 64 are provided on the side wall of the air box 3, and an arc plate 65 is fixedly provided on the slider 62. The end face of the arc plate 65 is fitted with the connecting hole 64, and it can close the remaining connecting holes 64 away from the counterweight block 63. When the counterweight block 63 drives the slider 62 to move to the bottom of the annular groove 61, the arc plate 65 will close the remaining main nozzles 4 except the bottom. A plurality of groups of connecting boxes 66 are arranged on the outside of the air box 3, and the connecting boxes 66 are provided with a plurality of and are respectively connected with the plurality of groups of connecting holes 64, and the plurality of main nozzles 4 are respectively connected with the connecting boxes 66.

[0032] The measuring head 2 is provided with a roller 7 at its end for rotation. When the measuring head 2 encounters an obstacle in a curve, the measuring head 2 can move over the obstacle through the roller 7 at its end, so that the measuring head 2 can move smoothly.

[0033] A rotating tube 8 is rotatably arranged inside the measuring head 2, a load block 9 is fixedly arranged at one end of the rotating tube 8 away from the roller 7, and a hose connected to the air box 3 is arranged on the rotating tube 8. A plurality of convex plates are arranged on the outer circumference of the roller 7. The rotating tube 8 can spray airflow to drive the convex plates to drive the roller 7 to rotate, so that the roller 7 rolls actively, and can cooperate with the reverse jet force of the airflow from the main nozzle 4 to assist the movement of the measuring head 2. At the same time, it can pass over obstacles more smoothly when encountering obstacles. In order to make the rotation direction of the roller 7 always drive the measuring head 2 forward, a load block 9 is fixed at the end of the rotating tube 8, so that when the measuring head 2 turns over, the mouth of the rotating tube 8 will rotate to a state where it can still drive the roller 7 to drive the measuring head 2 forward.

[0034] In summary, during measurement, the measuring tube 1 is laid out to allow the measuring head 2 to enter the mine, and the depth of the mine is calculated by the length of the measuring tube 1. When there is a bend in the mine, the measuring head 2 contacts the ground. At this time, air can be supplied to the measuring tube 1 through a high-pressure air pump, so that high-pressure air is ejected from the main nozzle 4, thereby driving the measuring head 2 to move through the bend.

[0035] Embodiment 2:

[0036] See also Figure 6 The difference between this embodiment and the first embodiment is that the annular groove 61 is composed of multiple smooth sections 10 and friction sections 11, and the positions of the friction sections 11 are all set on the normal line of the middle section of the side of the measuring head 2. The positions of the friction sections 11 are set at the corresponding side wall positions of the measuring head 2. When the measuring head 2 is tilted at a small angle, the component force of the gravity of the counterweight block 63 cannot overcome the friction between the slider 62 and the friction section 11, so that the slider 62 remains in place, and the arc plate 65 still closes the remaining main nozzles 4. When the measuring head 2 flips at a large angle, the component force of the gravity of the counterweight block 63 can overcome the friction between the slider 62 and the friction section 11, so that the counterweight block 63 moves to the bottom of the current position of the measuring head 2, completing the switching of the main nozzle 4.

[0037] Embodiment three:

[0038] See also Figure 7 The difference between this embodiment and the second embodiment is that the counterweight block 63 is plate-shaped and its top is rotatably connected to the slider 62. By rotatably setting the counterweight block 63, the weight of the counterweight block 63 can be better utilized to drive the slider 62 to move when the measuring head 2 rotates.

[0039] Embodiment 4:

[0040] See also Figure 8 The difference between this embodiment and the second embodiment is that the counterweight block 63 is a trapezoidal structure that is narrow at the top and wide at the bottom, and its top is rotatably connected to the slider 62, so that the bottom of the counterweight block 63 can be heavier, and the slider 62 can be driven to move more smoothly when the measuring head 2 flips.
