Description

Technical Field

[0001] The invention belongs to the technical field of karst cavity sonar detection, in particular to a karst cavity natural source surface wave sonar detection device. Background Art

[0002] The karst cavity natural source surface wave sonar detection device is an efficient and accurate underground karst cavity detection equipment. It uses the characteristics of sound waves propagating underground for detection. It has the advantages of wide detection range, high resolution and low cost. It has broad application prospects in engineering geological survey, geological disaster warning and resource exploration and development.

[0003] When using the existing karst cavity natural source surface wave sonar detection device, because the existing karst cavity natural source surface wave sonar detection device is generally a cylindrical device, it is placed on the ground when in use, emits sound waves, and then collects geological structure data in the karst cavity through the feedback of the sound waves, thereby obtaining a detailed topographic map of the interior of the cave. However, the terrain inside the cave is often complex and changeable, with many slopes, steps, protruding rocks and various gravel blocks. Therefore, the cylindrical sonar detection device may not be in a horizontal state during the placement process, which will cause the emission angle and receiving angle of the sound waves emitted by the sonar detection head to be not perpendicular to the horizontal plane, thereby causing an angular deviation between the measurement result and the actual topography inside the karst cavity.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0022] Embodiment 1 like Figure 1 to Figure 2As shown, a karst cavity natural source surface wave sonar detection device described in an embodiment of the present invention comprises a fixed box 1, an adjusting component is arranged inside the fixed box 1, a sonar detection head 2 is fixedly connected to the top of the adjusting component, and the adjusting component comprises a first cavity 11 opened in the fixed box 1; a positioning sleeve 214 is rotatably connected to the bottom wall of the first cavity 11, a rotating frame 211 is fixedly connected to the top of the positioning sleeve 214, an inner tube 222 is rotatably connected to the inside of the positioning sleeve 214, a fourth bevel gear 215 is fixedly connected to the top of the inner tube 222, an inner shaft 221 is rotatably connected to the middle part of the inner tube 222, a fifth bevel gear 216 is fixedly connected to the top of the inner shaft 221, a connecting rod 29 is rotatably connected to one end of the connecting rod 29, a second bevel gear 210 is fixedly connected to the one end of the connecting rod 29, a connecting frame 27 is fixedly connected to the circumferential surface of the connecting rod 29, a positioning column 26 is fixedly connected to one end of the connecting frame 27, and a positioning column 2 6 is rotatably connected with a fixed column 21, a first bevel gear 28 is fixedly connected to the lower surface of the fixed column 21, a sonar detection head 2 is clamped on the top of the fixed column 21, a fixed shaft 212 is fixedly connected to the other end of the rotating frame 211, a third bevel gear 213 is rotatably connected to the output end of the fixed shaft 212, the third bevel gear 213 is respectively meshed with the fifth bevel gear 216 and the first bevel gear 28, and the second bevel gear 210 is meshed with the fourth bevel gear 215; a second cavity 110 is opened at a position corresponding to the bottom end of the positioning sleeve 214 of the fixed box 1, a rotating gear 217 is fixedly connected to the bottom end of the positioning sleeve 214, a longitudinal rotation gear 219 is fixedly connected to the bottom end of the inner tube 222, a self-rotation gear 218 is fixedly connected to the bottom end of the inner shaft 221, and the tooth surfaces of the rotating gear 217, the longitudinal rotation gear 219 and the self-rotation gear 218 are all meshed with a rack plate 220, and the rack plate 220 is used to control the direction of the sonar detection head 2.

[0023] Specifically, when using the existing karst cavity natural source surface wave sonar detection device, because the existing karst cavity natural source surface wave sonar detection device is generally a cylindrical device, when it is placed on the ground, it will emit sound waves, and then the geological structure data in the karst cavity is collected through the feedback of the sound waves, so as to obtain a detailed topographic map inside the cave. However, the terrain inside the cave is often complex and changeable, with many slopes, steps, protruding rocks and various gravel blocks. Therefore, during the placement of the cylindrical sonar detection device, the sonar detection device may not be in a horizontal state, which may cause the emission and reception angles of the sound waves to change, thereby causing a deviation between the measurement result and the actual situation. This deviation may affect the accuracy of the topographic map, resulting in inaccurate maps. Therefore, the present invention solves this problem by setting a certain structure. First, when it is necessary to survey the karst cavity, the fixing box 1 is first placed on the ground of the cave. After fixing, the sonar detection head 2 is installed on the upper surface of the fixing column 21. After the sonar detection head 2 is installed, the top rack plate 220 is pushed, and the top rack plate 220 can drive the rotating gear 217 to rotate. The rotation of the rotating gear 217 will drive the positioning sleeve 214 fixed thereto, and then the positioning sleeve 214 will drive the rotating frame 211 to rotate. The rotation of the rotating frame 211 can adjust the direction of the sonar detection head 2. The direction of detection is determined first, and then the rack plate 220 in the middle is pushed to move. The rack plate 220 in the middle can drive the longitudinal gear 219 to rotate. The rotation of the longitudinal gear 219 can drive the inner tube 222 to rotate. The rotation of the inner tube 222 can drive the fourth bevel gear 215 fixed to one end thereof to rotate. Since the fourth bevel gear 215 is meshed with the second bevel gear 210, the fourth bevel gear 215 will drive the second bevel gear 210 to rotate. The rotation of the second bevel gear 210 will drive the connecting rod 29 to rotate, and then the connecting rod 29 can drive the connecting frame fixed to its circumferential surface. 27 is rotated, so that the angle of the sonar detection head 2 can be accurately adjusted, and the direction and angle of the survey are further accurately determined. At the same time, the self-rotating gear 218 at the bottom is pushed, and the rotation of the self-rotating gear 218 can drive the inner shaft 221 to rotate. The rotation of the inner shaft 221 can drive the fifth bevel gear 216 fixed to its top to rotate, and the rotation of the fifth bevel gear 216 can drive the third bevel gear 213 meshed with it, and then the third bevel gear 213 drives the first bevel gear 28 meshed with it, and the first bevel gear 28 will drive its fixed column 21 to rotate, and the rotation of the fixed column 21 will drive the fixed column 21 on its upper surface to rotate. The connected sonar detection head 2 rotates to make the sound wave emission angle more comprehensive. Due to the irregularity of the rock surface of the top wall of the karst cavity, when the sound wave is only emitted to one point, the diffusion of the sound wave will have certain limitations and cannot diffuse into the entire karst cavity. Therefore, when several sound wave emission points rotate, the sound waves emitted to the rock can be diverged at various angles, thereby improving the accuracy of the survey results, thereby completing the calibration of the survey position of the sonar detection head 2. Through the adjustment component, when the sonar detection head 2 is tilted, adaptive adjustment can be performed, thereby achieving accurate survey of the map data of the karst cavity and improving the survey accuracy. The problem that the terrain in the cave is often complex and changeable, with many slopes, steps, protruding rocks and various gravel blocks is solved. Therefore, the cylindrical sonar detection device may not be in a horizontal state during the placement process, which may cause the emission and reception angles of the sound waves to change, and then cause a deviation between the measurement result and the actual situation. This deviation may affect the accuracy of the topographic map and cause the drawn map to be inaccurate.

[0024] like Figure 3 As shown, in this embodiment, a slot 22 is provided on the upper surface of the fixing column 21, a bottom block 23 is fixedly connected to the lower surface of the sonar detection head 2, and a penetrating threaded hole 24 is provided on the surface of the bottom block 23 and the fixing column 21, and a screw 25 is threadedly connected in the threaded hole 24 of the fixing column 21.

[0025] Specifically, by rotating and unscrewing the screw 25 at the top of the fixing column 21, and then inserting the bottom block 23 on the lower surface of the sonar detection head 2 into the slot 22, the bottom block 23 is inserted into the slot 22, and the threaded hole 24 on the surface of the bottom block 23 will be aligned with the threaded hole 24 of the fixing column 21, and then the screw 25 is turned into the threaded hole 24, so that the bottom block 23 and the fixing column 21 are fixed together, thereby achieving the effect of being able to easily disassemble the sonar detection head 2.

[0026] like Figure 4 As shown, in this embodiment, a placement box 14 is fixedly connected to one side of the fixed box 1, and the placement box 14 is used to place the sonar detection head 2. Two rotating blocks 19 are fixedly connected to one side of the fixed box 1, and a protective cover 12 is rotatably connected between the two rotating blocks 19. The protective cover 12 is used to protect the adjustment components in the fixed box 1.

[0027] Specifically, a placement box 14 is fixedly connected to one side of the fixed box 1. When the sonar detection head 2 is not in use, the sonar detection head 2 is disassembled and placed in the placement box 14 for protection to prevent damage to the sonar detection head 2 during movement in the karst cavity. Therefore, the placement box 14 can improve the safety of the sonar detection head 2. At the same time, the protective cover 12 is rotated to cover the adjustment component in the first cavity 11 of the fixed box 1, thereby achieving the effect of protecting the adjustment component and improving the service life of the sonar detection equipment as a whole.

[0028] like Figure 4 As shown, in this embodiment, fixed guide plates 15 are fixedly connected to both sides of the placement box 14, and limiting grooves 112 are provided on the sides where the two fixed guide plates 15 are close to each other. Sealing plates 16 are slidably connected in the limiting grooves 112, and the sealing plates 16 are fixedly connected to limiting strips 111 at the positions corresponding to each limiting groove 112. The limiting strips 111 can slide along the limiting grooves 112, and a handle 18 is fixedly connected to one side of the sealing plate 16.

[0029] Specifically, after the sonar detection head 2 is placed in the placement box 14 for protection, the sealing plate 16 is pushed so that the sealing plate 16 can slide along the limiting groove 112 through the limiting strips 111 on both sides thereof, and then the sealing plate 16 can achieve sealing to prevent the sonar detection head 2 from being damaged. When it is needed to be taken out, the sealing plate 16 is pulled out by pulling the handle 18, and then the sonar detection head 2 can be taken out for surveying.

[0030] like Figure 4 As shown, in this embodiment, a magnetic plate 17 is fixedly connected to one side of the sealing plate 16 close to the protective cover 12 , and a magnetic suction groove 13 is opened at a position of the protective cover 12 corresponding to the magnetic plate 17 , and the magnetic plate 17 can be plugged into the magnetic suction groove 13 .

[0031] Specifically, during the process of the sealing plate 16 sealing the placement box 14, the magnetic plate 17 on one side of the sealing plate 16 will be inserted into the magnetic suction groove 13, so that the sealing plate 16 and the protective cover 12 can be secondary fixed, while improving the protection effect of the placement box 14 on the sonar detection head 2.

[0032] like Figure 4 As shown, in this embodiment, a third cavity 3 is opened in the placement box 14, and two arc-shaped protective blocks 31 are fixedly connected in the third cavity 3. The protective blocks 31 are rubber blocks, and an insertion frame 32 is fixedly connected to the bottom wall of the third cavity 3. The insertion frame 32 is used to fix the plug-in bottom block 23.

[0033] Specifically, two arc-shaped protective blocks 31 are fixedly connected to the inner wall of the third cavity 3 of the placement box 14. After the sonar detection head 2 is placed in the placement box 14, the sonar detection head 2 will be located between the two arc-shaped protective blocks 31 made of rubber material. At the same time, an insertion frame 32 is fixedly connected to the bottom wall of the third cavity 3, so that the bottom block 23 can be inserted into the insertion frame 32, thereby achieving better protection for the sonar detection head 2. The insertion frame 32 is also made of rubber material and has a certain elasticity, thereby better protecting the sonar detection head 2.

[0034] Embodiment 2 like Figures 2 to 11 As shown, compared with Example 1, another implementation of the present invention is: a plurality of positioning frames 4 are rotatably connected to the lower surface of the fixed box 1, and a positioning plate 41 is slidably connected to the interior of each positioning frame 4, and a connecting block 43 is fixedly connected to one side of each positioning plate 41. A connecting groove 413 is provided at the position of the positioning frame 4 corresponding to the connecting block 43, and the positioning plate 41 can slide along the connecting groove 413 through the connecting block 43.

[0035] Specifically, when using the sonar detection head 2, when the fixed box 1 is placed on the ground, several positioning frames 4 connected to the lower surface of the fixed box 1 are opened by rotating, and then the positioning plate 41 in the positioning frame 4 is pulled downward to adjust, so that the entire fixed box 1 is in a roughly horizontal position, and then the positioning plate 41 is fixed, so that the effect of facilitating the use of the adjustment component can be achieved.

[0036] like Figure 4 As shown, a clamping member is provided on one side of the positioning frame 4 of this embodiment, and the clamping member includes a transverse plate 44 fixedly connected to one side of the positioning frame 4, a transverse groove 45 is provided on the surface of the transverse plate 44, and sliding grooves 46 are provided on both sides of the inner wall of the transverse groove 45, and a slider 47 is slidably connected in the sliding groove 46, and a slide plate 48 is fixedly connected to the position of the slider 47 corresponding to each sliding groove 46, and an inserting plate 49 is slidably penetrated through the surface of the slider 47, and two compression springs 410 are fixedly connected to one end of the inserting plate 49, and the other ends of the two compression springs 410 are fixedly connected to the slider 47, and a clamping groove 411 is provided on the upper surface and the lower surface of one end of the inserting plate 49, and a rotating plate 412 is rotatably connected in the clamping groove 411, and the positioning frame 4 is fixedly connected to a limiting plate 414 at the position corresponding to the transverse plate 44, and a plurality of limiting holes 415 are provided on the surface of the limiting plate 414, and the inserting plate 49 can be inserted into the limiting hole 415.

[0037] Specifically, after the positioning plate 41 in each positioning frame 4 is adjusted, the plug plate 49 is pulled outward, and then the slider 47 is slid. At this time, the slider 47 can drive the plug plate 49 to slide inward and slide to the top of the connecting block 43 fixed to one side of the positioning plate 41, and then the plug plate 49 is abutted against the top of the connecting block 43, and the plug plate 49 is continuously pushed to squeeze the compression spring 410, and then the plug plate 49 can be inserted into the limiting hole 415 of the limiting plate 414. In the process of inserting the plug plate 49 into the limiting hole 415, the rotating plate 412 in the slot 411 at one end of the limiting plate 414 will be squeezed. After passing through the limiting hole 415, the rotating plate 412 is reset under the action of the built-in torsion spring. Fig. 9 As shown, the effect of the card-connecting plug-in plate 49 is achieved, and at the same time, the height adjustment of one of the positioning plates 41 is completed. Similarly, the heights of the other two positioning plates 41 are moderately adjusted, so that the fixed box 1 is roughly in a horizontal state, thereby improving the survey effect of the sonar detection head 2.

[0038] like Figure 4 As shown, in this embodiment, a rubber ball 42 is hinged at the bottom end of the positioning plate 41, and the rubber ball 42 is used to increase the friction between the positioning plate 41 and the stone.

[0039] Specifically, by connecting a rubber ball 42 at the bottom end of the positioning plate 41, when the positioning plate 41 contacts the stones in the cave, the bottom end of the positioning plate 41 may be stuck between the stones. Therefore, in order to improve the stability of the positioning plate 41, a rubber ball 42 is connected at the bottom end of the positioning plate 41, which increases the friction between the positioning plate 41 and the stones and improves the stability of the sonar detection head 2 during use.

[0040] like Figure 4 As shown, in this embodiment, a limiting member is arranged between every two positioning frames 4, and the limiting member includes two auxiliary blocks 5 fixedly connected to one side of each positioning frame 4, and an auxiliary frame 51 is rotatably connected between every two auxiliary blocks 5, and auxiliary grooves 53 are provided at one end of the two auxiliary frames 51 close to each other, and a spring 52 is fixed in each auxiliary groove 53, and the same auxiliary plate 54 is fixed between the two springs 52, and the auxiliary plate 54 can slide along the auxiliary groove 53.

[0041] Specifically, by setting a limit position between every two positioning frames 4, when the positioning plate 41 is rotated during the survey and fixation process, the auxiliary plate 54 between the two auxiliary blocks 5 will be pulled. Under the pulling force of the springs 52 at both ends, the auxiliary plate 54 can prevent each positioning frame 4 from having an excessive outward opening force, thereby preventing the positioning frame 4 from being excessively opened, causing the fixing box 1 to tip over and causing damage to the sonar detection head 2, thereby achieving the effect of protecting the sonar detection equipment.

[0042] Working principle: first, when it is necessary to survey the karst cavity, the fixed box 1 is first placed on the bottom surface of the cave, and the several positioning frames 4 that are rotatably connected on the lower surface of the fixed box 1 are opened by rotation, and then the positioning plate 41 in the positioning frame 4 is pulled downward for adjustment, and then the plug plate 49 is pulled outward, and then the slider 47 is slid, at this time, the slider 47 can drive the plug plate 49 to slide towards, slide to the top of the connecting block 43 fixed to one side of the positioning plate 41, and then make the plug plate 49 abut against the top of the connecting block 43, and continue to push the plug plate 49 to squeeze the compression spring 410, and then the plug plate 49 can be inserted into the limiting hole 415 of the limiting plate 414. In the process of inserting the plug plate 49 into the limiting hole 415, the rotating plate 412 in the slot 411 at one end of the limiting plate 414 will be squeezed, and when it passes through the limiting hole 415, the rotating plate 412 is reset under the action of the built-in torsion spring, as shown in the figure. Fig. 9 As shown, the effect of the card-connecting plug plate 49 is achieved, and at the same time, the height adjustment of one of the positioning plates 41 is completed, and the heights of the other two positioning plates 41 are moderately adjusted, so that the fixed box 1 is approximately in a horizontal state; After the fixation is completed, the screw 25 at the top of the fixing column 21 is screwed out by rotating, and then the bottom block 23 on the lower surface of the sonar detection head 2 is inserted into the slot 22. When the bottom block 23 is inserted into the slot 22, the threaded hole 24 on the surface of the bottom block 23 will be aligned with the threaded hole 24 of the fixing column 21, and then the screw 25 is turned into the threaded hole 24, so that the bottom block 23 and the fixing column 21 are fixed together, so that the sonar detection head 2 can be easily disassembled.
