Description

Technical Field

[0001] The present invention relates to the field of geological exploration devices, and in particular to a three-dimensional geological exploration device based on underground tunneling operations. Background Art

[0002] Underground excavation operations require further use of a three-dimensional geological detection module to conduct three-dimensional geological detection work underground in the underground passage based on the underground passage that has been excavated. This work is generally carried out using a three-dimensional geological detection module mounted on a mobile vehicle. The three-dimensional geological detection module is directly installed at the bottom of the chassis of the mobile vehicle, so that the three-dimensional geological detection module can be close to the ground at a close distance. Following the continuous movement of the mobile vehicle, it continuously conducts corresponding geological detection work on various areas below the ground and automatically draws an underground three-dimensional geological detection structure map. However, the ground of the underground passage is generally unpaved, so there is a large amount of accumulated sand and gravel and local raised slopes on the ground of the underground passage. These complex raised terrains will not only cause the mobile vehicle to cause high-frequency vibrations in the three-dimensional geological detection module during movement, but also affect The three-dimensional geological detection module is affected by the stable three-dimensional geological detection work. Since the three-dimensional geological detection module is at a short distance from the ground, the sand and gravel on the ground and the local raised slopes are likely to cause serious scratches on the three-dimensional geological detection module, affecting the safe three-dimensional geological detection work of the three-dimensional geological detection module. To address this problem, the prior art, such as a geological radar detector for tunnel structure detection described in CN107728219A, can avoid the sand and gravel and raised slope areas on the ground by actively lifting the detection components upward, but this method will cause the three-dimensional geological detection module to be too high from the ground, affecting the three-dimensional detection effect of the three-dimensional geological detection module, and the frequent reciprocating movement of the three-dimensional geological detection module up and down will seriously affect the mapping effect of the drawn underground three-dimensional geological detection structure map. Summary of the invention

[0003] In order to overcome the disadvantage that frequent reciprocating movement of the three-dimensional geological detection module up and down to avoid the raised terrain on the ground will seriously affect the mapping effect of the drawn underground three-dimensional geological detection structure map, the present invention provides a three-dimensional geological detection device based on underground excavation operations.

DETAILED DESCRIPTION

[0017] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments, but is not intended to limit the present invention. Example 1

[0018] A three-dimensional geological exploration device based on underground excavation operations, such as Figure 1-Figure 7 As shown, it includes a frame body 11, moving wheels 12, a control rod 13, a spring shock absorber 14, an electric telescopic rod 15, a lift cabin 2, a three-dimensional geological detection module 21, a protective bottom plate 3, a first compression spring 31, a distance sensor 34 and a shovel board 4; four moving wheels 12 are installed on the frame body 11; a control rod 13 for manually controlling the moving speed is installed on the frame body 11; the lift cabin 2 is slidably connected to the inner bottom of the frame body 11; a spring shock absorber 14 is fixedly connected to the frame body 11; the telescopic end of the spring shock absorber 14 is fixedly connected to the lift cabin 2; four movable cavity structures 201 are opened on the lift cabin 2; Four electric telescopic rods 15 are installed; the telescopic ends of the four electric telescopic rods 15 are respectively located in the corresponding active cavity structures 201 of the elevator cabin 2; two three-dimensional geological detection modules 21 are installed at the bottom of the elevator cabin 2; the bottom of the elevator cabin 2 is rotatably connected to a protective base plate 3 through a rotating shaft; the protective base plate 3 is provided with two hollow groove structures 301 corresponding to the two three-dimensional geological detection modules 21 respectively; four first compression springs 31 are fixedly connected between the protective base plate 3 and the front side of the elevator cabin 2; eight distance sensors 34 are installed at the bottom of the elevator cabin 2; a mud shoveling plate 4 is fixedly connected to the front side of the protective base plate 3, and the middle part of the mud shoveling plate 4 is set as a pointed cone structure.

[0019] like Figure 4 and Figure 6As shown, the lift cabin 2 is equipped with first pressure sensors 32 corresponding to the number of first compression springs 31; one end of each first compression spring 31 connected to the lift cabin 2 is respectively fixedly connected to the sensing component of the corresponding first pressure sensor 32; each hollow groove structure 301 of the protective base plate 3 is fixedly connected with a transparent protective sheet 33, and the transparent protective sheet 33 provides anti-scratch protection for the three-dimensional geological detection module 21 at the bottom of the lift cabin 2.

[0020] like Figure 6 and Figure 7 As shown, the front end of the mud shoveling board 4 is configured as a sawtooth structure 401 ; a baffle 41 is fixedly connected to the mud shoveling board 4 , and the baffle 41 blocks and intercepts the sand and stones shoveled backward and upward by the mud shoveling board 4 .

[0021] The following are the working steps of a three-dimensional geological exploration device based on underground excavation operations of the present invention.

[0022] The staff holds the control lever 13 and pushes the frame body 11 to drive the moving wheel 12 to move in the underground channel. At the same time, the three-dimensional geological detection module 21 continuously performs three-dimensional geological detection work below the ground, and continuously draws a three-dimensional geological detection structure map of the underground. In this process, the spring shock absorber 14 provides shock absorption treatment for the three-dimensional geological detection module 21 at the bottom of the lifting cabin 2, so that the three-dimensional geological detection work of the three-dimensional geological detection module 21 can be carried out in a stable mobile environment. At the same time, the mud shovel board 4 timely removes the mud and gravel in the forward direction of the ground through the sawtooth structure 401, so as to avoid the three-dimensional geological detection module 21 from being seriously scratched by the mud and sand during the process of passing through the mud and sand. There is no need to frequently lift the three-dimensional geological detection module 21 up and down, so that the three-dimensional geological detection module 21 is more in a state close to the ground for detection work, thereby improving the three-dimensional geological detection effect of the three-dimensional geological detection module 21.

[0023] When a local raised slope appears in the forward direction of the ground, the shovel board 4 first hits the local raised slope of the ground. At this time, the shovel board 4 hitting the local raised slope of the ground flips upward under the restriction of the rotating shaft of the protective base plate 3, and the shovel board 4 drives the protective base plate 3 upward to squeeze the first compression spring 31. At the same time, the first pressure sensor 32 can recognize that the first compression spring 31 is squeezed at the first time, so that the first pressure sensor 32 transmits a start command to the electric telescopic rod 15 through the circuit system, so that the four electric telescopic rods 15 simultaneously pull the lifting cabin 2 through the active cavity structure 201 to drive the three-dimensional geological detection module 21 to rise up and away from the ground. At the same time, the lifting cabin 2 drives the protective base plate 3 and the shovel board 4 to rise up and leave the local raised slope of the ground, so that in the process of smoothly passing through the local raised slope of the ground, the local raised slope of the ground will not contact the three-dimensional geological detection module 21 and cause scratches, thereby providing safety protection for the three-dimensional geological detection work of the three-dimensional geological detection module 21.

[0024] At the same time, the distance sensor 34 continuously monitors the height of the elevator cabin 2 from the ground. This monitoring work can detect whether the current moving position of the elevator cabin 2 has left the local raised slope on the ground. After the distance sensor 34 detects that the elevator cabin 2 has left the local raised slope on the ground, the distance sensor 34 transmits a reset command to the electric telescopic rod 15 through the circuit system, so that the four electric telescopic rods 15 simultaneously drive the elevator cabin 2 and the three-dimensional geological detection module 21 to move downward and reset, allowing the three-dimensional geological detection module 21 to return to the close-range detection position with the ground.

[0025] When the raised slope on the ground is composed of loose soil, the forward-moving shovel board 4 will directly shovel up the soft soil, and push the continuously shoveled soil to the left and right sides through the pointed cone structure in the middle of the shovel board 4, so as to shovel the raised slope composed of the soil on the ground into a flat ground. At this time, there is no need to frequently lift the three-dimensional geological detection module 21 up and down, and the three-dimensional geological detection module 21 can be more in a state of being close to the ground for detection work, thereby improving the three-dimensional geological detection effect of the three-dimensional geological detection module 21. Example 2

[0026] like Figure 1-Figure 8 As shown, on the basis of Example 1, a suction machine 5 and a suction pipe group are installed on the frame body 11 of this embodiment; the inlet end of the suction machine 5 is connected to the suction pipe group; the outlet end of the suction machine 5 is toward the rear side of the frame body 11; the suction pipe group is connected to the baffle 41; the mud shovel board 4 is connected to the fixing frame 6; the bottom of the fixing frame 6 is connected to a plurality of water suction discs 61 equidistantly distributed in the left and right directions; the suction pipe group is connected to all the water suction discs 61; the mud shovel board 4 is fixed with a screen 42 for filtering accumulated water downwards.

[0027] The suction pipe group includes a first suction pipe 51, a second suction pipe 52, a third suction pipe 53 and a fourth suction pipe 54; the first suction pipe 51 is fixedly connected to the frame body 11; the first suction pipe 51 is connected to the inlet end of the suction machine 5; the third suction pipe 53 is fixedly connected to the baffle 41; four second suction pipes 52 are commonly connected between the first suction pipe 51 and the third suction pipe 53, and the second suction pipes 52 use a hose material that can be bent up and down; the third suction pipe 53 is connected to fourth suction pipes 54 corresponding to the number of water suction discs 61; each fourth suction pipe 54 is respectively connected to a corresponding water suction disc 61; the bottom of each water suction disc 61 is wrapped with a filter cotton 62 for filtering mud and sand, so as to prevent a large amount of fine sand and gravel from being sucked into the suction machine 5 by the water suction disc 61 along with the accumulated water, causing the suction components of the suction machine 5 to be hit by a large amount of fine sand and gravel and be damaged.

[0028] When there is a small amount of accumulated water on the ground of the underground passage that has not been drained away, the accumulated water will cause great interference to the three-dimensional geological detection work of the three-dimensional geological detection module 21. In order to reduce the interference of the accumulated water on the three-dimensional geological detection work, the accumulated water on the ground needs to be drained away in advance before the lift cabin 2 passes through the accumulated water. Therefore, when the staff controls the joystick 13 to drive the frame body 11 to move, the shovel board 4 first shovels into the accumulated water to shovel the sand and stones in the accumulated water, and only allows the accumulated water to flow downward through the screen 42 to the water absorption Below the plate 61, the suction machine 5 sucks the water absorption plate 61 through the suction pipe group, so that the accumulated water passes through the filter cotton 62, the water absorption plate 61, the fourth suction pipe 54, the third suction pipe 53, the second suction pipe 52 and the first suction pipe 51 to be sucked into the suction machine 5, and then the accumulated water is discharged to the rear side of the frame body 11 through the outlet end of the suction machine 5, thereby greatly reducing the amount of water accumulated at the bottom of the lift cabin 2 and reducing the influence of the accumulated water on the three-dimensional geological detection work of the three-dimensional geological detection module 21.

[0029] When the first pressure sensor 32 recognizes that the lift cabin 2 passes through a locally raised slope on the ground, the electric telescopic rod 15 promptly lifts the lift cabin 2, the three-dimensional geological detection module 21, the protective bottom plate 3, the shovel board 4, the fixing frame 6 and each water suction tray 61 upward to avoid the locally raised slope on the ground.

[0030] When the raised slope on the ground is composed of soft soil, the shovel board 4 will directly flatten the soil in the manner of the above embodiment, without driving the three-dimensional geological detection module 21, the fixing frame 6 and each water absorption tray 61 to rise up for avoidance. Example 3

[0031] like Figure 1-Figure 8 As shown, on the basis of Example 2, the fixing frame 6 of this embodiment is fixedly connected to the frame body 11 through the fixing rod 64; the fixing frame 6 is slidably connected to the mud shovel board 4; all the water suction discs 61 are slidably connected to the fixing frame 6; second pressure sensors 66 corresponding to the number of water suction discs 61 are installed on the fixing frame 6; a second compression spring 63 is fixedly connected between all the water suction discs 61 and the second pressure sensors 66, and the second compression spring 63 is wound around the fourth suction pipe 54 corresponding to the water suction disc 61; the fourth suction pipe 54 uses a hose material that can be bent up and down; each fourth suction pipe 54 is respectively installed with an electric control valve 65, and all the electric control valves 65 are in an open state.

[0032] When the staff controls the joystick 13 to drive the frame body 11 to move, when the first pressure sensor 32 recognizes that the lift cabin 2 passes through a local raised road surface on the ground, the electric telescopic rod 15 promptly lifts the lift cabin 2, the three-dimensional geological detection module 21, the protective bottom plate 3 and the shovel board 4. At this time, the fixed frame 6 and all the water absorption plates 61 are restricted by the frame body 11 and will not rise upward, so that all the water absorption plates 61 are kept close to the ground through the filter cotton 62 to absorb water. In this process, when one or more of the water absorption plates 61 pass through the local raised slope of the ground through the filter cotton 62, the water absorption plate 61 is squeezed by the local raised slope of the ground and pushes the second compression spring 63 to compress upward. At the same time, the compressed second compression spring 63 generates a downward reverse thrust on the water absorption plate 61, so that the water absorption plate 61 is close to the local raised slope of the ground under the action of the reverse thrust, so that the water absorption plate 61 can It can smoothly pass through the local raised slope of the ground. At the same time, when the water suction plate 61 pushed upward compresses the second compression spring 63, it will trigger the corresponding second pressure sensor 66, so that the second pressure sensor 66 quickly controls the same group of electric control valves 65 through the circuit system to switch to a closed state, so that the corresponding fourth suction pipe 54 of the water suction plate 61 pushed upward cannot be in a suction state. Therefore, the water suction plate 61 pushed upward will not perform suction work after leaving the water accumulation area. Only the remaining water suction plates 61 that have not been pushed upward are kept in the non-raised slope area close to the ground to perform water suction work, so as to avoid the water suction plate 61 pushed upward directly sucking air due to no contact with the accumulated water, resulting in the remaining water suction plates 61 that are sucking the accumulated water failing to complete the water suction work normally, thereby ensuring the continuous and efficient suction of the accumulated water at the bottom of the elevator cabin 2, and also ensuring the stable three-dimensional geological exploration work.

[0033] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
