Description

Technical Field

[0001] This invention relates to the field of geological disaster crack measurement technology, and in particular to a geological disaster crack measurement device. Background Technology

[0002] Surface cracks are a key precursor to geological disasters such as landslides and debris flows. By monitoring the width, depth and expansion rate of cracks in real time, potential risks can be identified in advance and early warning mechanisms (such as audible and visual alarms or remote notifications) can be triggered, buying valuable time for personnel evacuation and emergency response.

[0003] Chinese patent CN208751423U discloses a geological hazard crack measuring device. The device features a first and second sleeve installed on one side of a telescopic rod, allowing the two sleeves to slide back and forth on the rod. A first measuring strip and a second measuring strip are respectively installed at the bottom of the first and second sleeves. This design allows the user to slide the sleeves to move the first and second measuring strips against the two sides of the crack, thus greatly improving the accuracy of the measured data.

[0004] Regarding the aforementioned related technologies, the inventors believe that the following defects exist:

[0005] When the above-mentioned equipment is used for measurement, it cannot quickly and directly obtain the measured length and depth data. The final result needs to be calculated manually, which reduces efficiency and is prone to errors. Summary of the Invention

[0006] To address the technical problems mentioned in the background section, this invention provides a geological disaster crack measurement device.

[0007] The present invention is achieved by the following technical solution: a geological disaster crack measuring device, comprising a device body, a telescopic adaptation component, a horizontal moving component, and a depth detection component.

[0008] A telescopic adaptation component is provided on one side of the device body to keep the device body stable on complex ground and to allow for vertical displacement adjustment. A horizontal moving component is movable on the other side of the device body. The horizontal moving component includes a movable block 1, which slides horizontally along the length extension direction of the device body. A depth detection component is connected to the outside of the movable block 1 to accommodate the detection and adjustment of horizontal distance.

[0009] When performing depth detection, the depth value can be obtained simultaneously.

[0010] As a further improvement to the above solution, the telescopic adaptor includes a circular vertical hole vertically opened at the device body, a vertical rod body vertically slidably connected inside the vertical hole, side grooves symmetrically opened on both sides of the vertical hole, side strips vertically slidably connected inside the side grooves, the inner side of the side strips fixedly connected to the vertical rod body, a support platform coaxially fixedly connected to the bottom end of the vertical rod body outside the device body, a threaded slot hole opened at the middle of the top of the vertical rod body, a screw threadedly connected inside the threaded slot hole, a knob fixedly connected to the top of the screw, a rotating ring block fixedly connected to the screw on the top outer wall of the device body, a positioning ring sleeve rotatably connected to the rotating ring block, the outer side of the positioning ring sleeve fixedly connected to the top of the device body, one side of the vertical rod body and the extension direction of the device body are both horizontally set, and a vertical ruler is connected to the outer wall of the horizontal vertical rod body.

[0011] As a further improvement to the above scheme, two transverse grooves are symmetrically opened in the middle of the outer walls on both sides of the device body. Each transverse groove is slidably connected to a sliding sleeve block, and damping is provided at the connection between the sliding sleeve block and the transverse groove. Each sliding sleeve block is vertically slidably connected to a sliding rod. The bottom ends of each sliding rod are extended and fixedly connected to a support platform two. The support platform two has the same size as the support platform one, and the bottom surfaces of the support platform one and the support platform two are coplanar. The top center of the support platform two is connected to a semi-ring block one. One side of the semi-ring block one is symmetrically fixedly connected to an inner rod, and both inner rods are slidably connected to outer rods. One side of each of the two outer rods is fixedly connected to a semi-ring block two, and the semi-ring block two is fixedly connected to the top of the support platform one.

[0012] As a further improvement to the above solution, the horizontal moving component includes a movable cavity opened on one side of the device body, the movable cavity being slidably connected to a movable block, a slider extending from the inner side of the movable block, damping rubber being provided at the sliding connection between the slider and the movable cavity, and a horizontal scale line being engraved on the outer wall of the movable block.

[0013] As a further improvement to the above solution, the depth detection component includes an extension assembly, a reading assembly, and a striking assembly. The striking assembly can drive the extension assembly to vertically displace, and the crack depth can be quickly determined by the reading assembly connected to the extension assembly. The extension assembly includes a sliding cavity, which is vertically opened outside the movable block. A stopper plate is vertically slidably connected inside the sliding cavity. A sealing rubber ring is provided at the connection between the stopper plate and the sliding cavity. A cone is fixedly connected to the middle of the bottom end of the stopper plate, with a pointed bottom. A rack plate is fixedly connected to one side of the outer wall of the cone. The striking assembly includes components extending above the sliding cavity... The pipe wall has an annular block extending outward from its top. A second plug plate is vertically slidably connected inside the pipe wall. Multiple connecting plates are coaxially fixed to the top of the second plug plate, surrounding its top. The second plug plate has a hole at its bottom, with a valve plate attached to the bottom of the hole. A second rotating rod is fixedly connected to one side of the valve plate, with rotating sleeves rotatably connected to both ends. Two rotating sleeves are fixedly connected to the bottom of the second plug plate. Push rods are fixedly connected to the tops of the multiple connecting plates, with protrusions extending from their bottoms. These protrusions slidably connect to the inner wall of the pipe, and a second sealing rubber ring is installed at the connection point. The protrusions and the annular block... A spring is connected in the middle of the block, and a spring is set on the outer wall of the push rod. A connecting pipe is connected to one side of the outer wall of the pipe, and a liquid tank is connected to the other side of the connecting pipe. The liquid tank is connected to the pipe wall through the connecting pipe. One side of the liquid tank is fixedly connected to the outer wall of the pipe, and an opening is fixedly connected to the top of the other side of the liquid tank. A plug is inserted into the opening, and a vent hole is opened at the top of the plug. Liquid is placed in the liquid tank. When the push rod is stretched, the valve plate unfolds, allowing the liquid at the connecting pipe to enter the sliding cavity. When the push rod is pressed down, the valve plate locks and pushes the plug plate vertically downward by the liquid. Repeating the previous operation can achieve orderly operation. The stopper plate is now moved vertically downwards and tested. A semi-circular adjustment groove is opened at the top of the push rod, and a rotating rod is rotatably connected at the center of the adjustment groove. An adjustment block is fixedly connected to the top of the rotating rod at the adjustment groove, and the top of the adjustment block has a protrusion. A wedge is fixedly connected to the bottom of the rotating rod at the stopper plate. The longitudinal section of the wedge is a right-angled triangle, and the right-angle end is connected to the bottom of the rotating rod. The two sides of the wedge are inclined. When the push rod is stretched, the adjustment block is rotated to make the wedge block block the valve plate. This makes it easy for the valve plate to not completely block the liquid when the push rod is pressed down, so that the liquid returns to the liquid tank and the cone can be easily recovered.

[0014] As a further improvement to the above scheme, the reading component includes two positioning plates fixedly connected to the bottom outer side of the movable block 1. The longitudinal section of the positioning plates is convex. Gear 1 and Gear 2 are rotatably connected to both sides of the two positioning plates, respectively. Gear 1 and Gear 2 mesh with each other. The other side of Gear 1 meshes with a rack plate. A housing is fixedly connected to the bottom of the movable block 1. The housing is fitted over Gear 1 and Gear 2. The central shaft of Gear 2 passes through the housing and is coaxially fixedly connected to a rotating shaft on the outside. Vertical slots are symmetrically opened on both sides of the rotating shaft. Sleeves are slidably connected to the vertical slots. A ball block is fixedly connected to the inner wall of the sleeve. A round block is slidably connected to the ball block. The round block is fixedly connected to the outer wall of the housing, and a spiral groove is opened on the inner side of the round block. The rotating groove has a sleeve fixedly connected to a circular plate outside the circular block. An outer rod is fixedly connected to the outer wall of the circular plate. The outer rod is radially arranged along the rotation axis. A movable block two is radially slidably connected inside the outer rod. A ball is embedded on the outer side of the movable block two. A spring two is connected between the inner end of the movable block two and the circular plate. An outer cylinder is fixedly connected to the outer wall of the outer shell. The outer cylinder is coaxial with the rotation axis. The outer cylinder has multiple levels of layered blocks. The diameter of the layered blocks decreases as they move inward, and the height of the layered blocks increases as they move outward. Precise graduation lines are opened on the outer wall of the outer shell in the circumferential direction of the layered blocks. Cutting grooves are opened above multiple layered blocks to guide the outer rod, which slides outward with the rotation, to fit into different levels of layered blocks, facilitating subsequent reading and processing.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] (i) The present invention utilizes telescopic adaptable components for vertical adjustment, thereby enabling adjustment and support for complex ground conditions, and further improves the adaptability of the device to complex terrain by cooperating with horizontal moving components.

[0031] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0032] Example 1: Please refer to Figures 1-4 This embodiment of a geological disaster crack measuring device includes a device body 1, an extension and adaptation component, a horizontal movement component, and a depth detection component.

[0033] A telescopic adaptation component is provided on one side of the device body 1 to keep the device body 1 stable on complex ground and to allow for vertical displacement adjustment.

[0034] On the other side of the device body 1, there is a horizontal moving component, which includes a movable block 20. The movable block 20 slides horizontally along the length extension direction of the device body 1, and a depth detection component is connected to the outside of the movable block 20 to adapt to the detection and adjustment of horizontal distance.

[0035] When performing depth detection, the depth value can be obtained simultaneously.

[0036] The telescopic adaptation component includes a vertical hole 2 vertically opened at the device body 1. A vertical rod 4 is vertically slidably connected inside the vertical hole 2. Side grooves 3 are symmetrically opened on both sides of the vertical hole 2. Side strips 19 are vertically slidably connected inside the side grooves 3. The inner side of the side strips 19 is fixedly connected to the vertical rod 4. A support platform 5 is coaxially fixedly connected to the bottom end of the vertical rod 4 outside the device body 1. A threaded slot is opened in the middle of the top of the vertical rod 4. A screw 6 is threadedly connected inside the threaded slot. A knob 7 is fixedly connected to the top of the screw 6. A rotating ring block 8 is fixedly connected to the screw 6 on the top outer wall of the device body 1. A positioning ring sleeve 9 is rotatably connected to the rotating ring block 8. The positioning ring sleeve 9 extends outward and is fixedly connected to the top of the device body 1. One side of the vertical rod 4 is horizontally set in the direction of extension of the device body. A vertical ruler 18 is connected to the outer wall of the horizontal vertical rod.

[0037] Two transverse grooves 10 are symmetrically opened in the middle of the outer walls on both sides of the device body 1. Each transverse groove 10 is slidably connected to a sliding sleeve block 11, and a damping is provided at the connection between the sliding sleeve block 11 and the transverse groove 10. Each sliding sleeve block 11 is vertically slidably connected to a sliding rod 12. The bottom ends of each sliding rod 12 are extended and fixedly connected to a support platform 2 13. The support platform 2 13 has the same size as the support platform 1 5. The bottom surfaces of the support platform 1 5 and the support platform 2 13 are coplanar. A semi-ring block 14 is connected to the middle of the top of the support platform 2 13. An inner rod 15 is symmetrically fixedly connected to one side of the semi-ring block 14, and both inner rods 15 are slidably connected to outer rods 16. Each outer rod 16 is fixedly connected to one side of a semi-ring block 2 17, and the semi-ring block 2 17 is fixedly connected to the top of the support platform 1 5.

[0038] The horizontal moving component includes a movable cavity opened on one side of the device body 1. The movable cavity is slidably connected to the movable block 20. A slider extends from the inner side of the movable block 20. Damping rubber is provided at the sliding connection between the slider and the movable cavity. A horizontal scale line (not shown) is engraved on the outer wall of the movable block 20.

[0039] The implementation principle of a geological disaster crack measuring device in this application embodiment is as follows:

[0040] Move the device body 1 to the area where crack measurement is required, and adjust it according to the flatness of the ground. When the ground is complex and not flat enough, the distance between the support platform 1 and the support platform 2 13 can be adjusted by the horizontally sliding support platform 2 13, in conjunction with the inner rod 15 and the outer rod 16, so that the device body 1 can be fixed as a whole.

[0041] With the rotation of knob 7, the screw 6 and the threaded slot of the vertical rod 4 are connected to move the entire support platform 5 and the semi-ring block 17 vertically downward, thereby ensuring the stability of the equipment during measurement in complex terrain.

[0042] As the support platform 5 moves vertically downwards, the scale of the vertical ruler 18, which is exposed below the device body 1, allows for easy subtraction of the scale of the vertical ruler 18 during subsequent depth testing to obtain the actual crack depth data.

[0043] Example 2: Combination Figures 1-3 as well as Figure 5 and Figure 6 This embodiment is an improvement on embodiment 1, further described in the following aspects:

[0044] The depth detection component includes an extension assembly, a reading assembly, and a striking assembly. The striking assembly drives the extension assembly to move vertically, and the reading assembly connected to the extension assembly can quickly determine the crack depth. The extension assembly includes a sliding cavity 21, which is vertically opened outside the movable block 20. A plug plate 22 is vertically slidably connected inside the sliding cavity 21. A sealing rubber ring is provided at the connection between the plug plate 22 and the sliding cavity 21. A cone 23 is fixedly connected to the middle of the bottom end of the plug plate 22. The bottom of the cone 23 is pointed. A rack plate 40 is fixedly connected to one side of the outer wall of the cone 23. The striking assembly includes a tube wall 24 extending above the sliding cavity 21. A ring block extends outward from the top of the tube wall 24. A vertical sliding block is located inside the tube wall 24. A second stopper plate 25 is dynamically connected. Multiple connecting plates 26 are coaxially fixedly connected to the top of the second stopper plate 25, surrounding the top of the second stopper plate 25. A hole is formed at the bottom of the second stopper plate 25 near the connecting plates 26, and a valve plate 35 is attached to the bottom of the hole. A rotating rod 34 is fixedly connected to one side of the valve plate 35. Rotating sleeve blocks 33 are rotatably connected to both ends of the rotating rod 34, and the two rotating sleeve blocks 33 are fixedly connected to the bottom of the second stopper plate 25. Push rods 27 are fixedly connected to the top of each of the multiple connecting plates 26. A protrusion extends from the bottom of the push rod 27 and slides against the inner wall of the pipe wall 24. A sealing rubber ring 2 is provided at the connection point. A spring 28 is connected between the protrusion and the ring block, and the spring 28 is sleeved on the outer wall of the push rod 27. A connecting pipe 36 is connected to one side of the outer wall of the pipe wall 24, and a liquid tank 37 is connected to the other side of the connecting pipe 36. The liquid tank 37 is connected to the pipe wall 24 via the connecting pipe 36. One side of the liquid tank 37 is fixedly connected to the outer wall of the pipe wall 24, and an opening 38 is fixedly connected to the top of the other side of the liquid tank 37. A plug 39 is inserted into the opening 38, and a vent hole is opened at the top of the plug 39. Liquid is placed in the liquid tank 37 to realize the one-way valve function of the valve plate 35. When the push rod 27 is stretched, the valve plate 35 can be unfolded to allow the liquid at the connecting pipe 36 to enter the slide cavity 21. When the push rod 27 is pressed down, the valve plate 35 is locked and the plug plate 22 is pushed vertically downward by the liquid. Repeating the previous operation can realize the plug in an orderly manner. Plate 22 moves vertically downward and is tested; the top of push rod 27 has a semi-circular adjustment groove 29, and a rotating rod 30 is rotatably connected to the center of the adjustment groove 29. The top of the rotating rod 30 is fixedly connected to the adjustment block 31 at the adjustment groove 29, and the top of the adjustment block 31 has a protrusion. The bottom of the rotating rod 30 is fixedly connected to the wedge block 32 at the stop plate 25. The longitudinal section of the wedge block 32 is a right triangle, and the right angle end is connected to the bottom end of the rotating rod 30. The two sides are inclined. When the push rod 27 is stretched, the adjusting block 31 is rotated to make the wedge block 32 block the valve plate 35, so that the valve plate 35 will not completely block the liquid when the push rod 27 is pressed down, so that the liquid returns to the liquid tank 37, which facilitates the recovery of cone 23.

[0045] The implementation principle of a geological disaster crack measuring device in this application embodiment is as follows:

[0046] After the equipment is placed, it can be further adapted by sliding the movable block 20. As the movable block 20 slides, it drives the liquid tank 37 to move synchronously and can quickly pull the push rod 27 up. As the push rod 27 rises, the valve plate 35 will open along the rotating rod 34, allowing the liquid to enter below the valve plate 35. At the same time, the water in the liquid tank 37 enters the sliding cavity 21 along the connecting pipe 36 and is at the top of the plug plate 22 under gravity. Then, the push rod 27 can be released, and the entire push rod 27 will move down under the elasticity of the spring 28, causing the valve plate 35 and the plug plate 25 to close. The liquid is pushed and, with the liquid as the medium, the plug plate 22 moves down along the sliding cavity 21. The above operation is repeated until the bottom of the cone 23 can no longer move down easily at the bottom of the crack. The distance that the plug plate 22 has moved down can be obtained.

[0047] When the stopper plate 22 needs to be recovered, pressure is applied to the bottom end of the cone 23, and the adjusting block 31 is rotated synchronously so that the wedge block 32 at the bottom end can limit the valve plate 35 that opens as it rises, thereby facilitating the free entry of liquid into the connecting plate 26, and allowing excess liquid to enter the liquid tank 37 through the connecting pipe 36, thus realizing equipment recovery.

[0048] Example 3: Combination Figure 3 as well as Figures 5-10 This embodiment is further improved upon Embodiments 1 and 2 in the following ways:

[0049] The reading assembly includes two positioning plates 41 fixedly connected to the bottom outer side of the movable block 20. The longitudinal section of the positioning plates 41 is convex. Gear 1 43 and gear 2 44 are rotatably connected to both sides of the two positioning plates 41, respectively. Gear 1 43 and gear 2 44 mesh with each other. The other side of gear 1 43 meshes with a rack plate 40. A housing 42 is fixedly connected to the bottom of the movable block 20. The housing 42 is fitted over gear 1 43 and gear 2 44. The central axis of gear 2 44 passes through the housing 42 and is coaxially fixedly connected to a rotating shaft 45 on the outside. Vertical slots are symmetrically opened on both sides of the rotating shaft 45. Sleeves 46 are slidably connected to the vertical slots. A ball block 47 is fixedly connected to the inner wall of the sleeve 46. A round block 48 is slidably connected to the ball block 47. The round block 48 is fixedly connected to the outer wall of the housing 42, and a spiral sliding groove 49 is opened on the inner side of the round block 48. A circular plate is fixedly connected to the sleeve 46 outside the round block 48. An outer rod 5 is fixedly connected to the outer wall of the circular plate. 0. The outer rod 50 is radially arranged along the rotating shaft 45. A movable block 52 is slidably connected to the inner radial direction of the outer rod 50. A ball 53 is embedded on the outer side of the movable block 52. A spring 51 is connected between the inner end of the movable block 52 and the circular plate. An outer cylinder 54 is fixedly connected to the outer wall of the outer shell 42. The outer cylinder 54 is coaxially arranged with the rotating shaft 45. The outer cylinder 54 is provided with multi-level layered blocks 55. The diameter of the layered blocks 55 decreases as they go inward, and the height of the layered blocks 55 increases as they go outward. Specifically, the innermost layered block 55 extends outward in sequence to increase the counting unit, such as the horizontal groove 10, the movable block 20, the rotating rod 30, and so on. The depth gradually increases from the outside to the inside. The outer wall of the outer shell 42 is provided with precise scale lines in the inner circumference of the layered blocks 55. A cutting groove 56 is provided above each of the multiple layered blocks 55 to guide the outer rod 50, which slides outward with rotation, to fit into different levels of layered blocks 55, facilitating subsequent reading processing.

[0050] The implementation principle of a geological disaster crack measuring device in this application embodiment is as follows:

[0051] As the stopper plate 22 moves downward, the rack plate 40 can be driven to rotate along with the gear 44 by sequentially meshing with the gear 43 and the gear 44. The sleeve 46 is slidably connected to the vertical slot of the shaft 45, causing the sleeve 46 to rotate as well. The sleeve 46 slides outward through the ball block 47 and the sliding groove 49. After rotating one revolution, it can abut against the layer block 55 of another layer. When the sleeve 46 drives the outer rod 50 to rotate, the layer block 55 can be changed along the cutting groove 56. Thus, the depth of the crack can be quickly determined according to the different layers of the layer block 55 and the precise scale lines opened in the circumference.

[0052] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.

Each groove is slidably connected to a sliding sleeve block, and damping is provided at the connection between the sliding sleeve block and the groove. Each sliding sleeve block is vertically slidably connected to a sliding rod. The bottom ends of the two sliding rods are extended and fixedly connected to a second support platform. The second support platform has the same dimensions as the first support platform, and the bottom surfaces of the first and second support platforms are coplanar. A semi-ring block is connected to the middle of the top of the second support platform. An inner rod is symmetrically fixedly connected to one side of the semi-ring block, and both inner rods are slidably connected to outer rods. A semi-ring block is fixedly connected to one side of each of the two outer rods, and the semi-ring block is fixedly connected to the top of the first support platform.

4. The geological disaster crack measuring device as described in claim 1, characterized in that, The horizontal moving component includes a movable cavity formed on one side of the device body. The movable cavity is slidably connected to a movable block. A slider extends from the inner side of the movable block, and a damping rubber is provided at the sliding connection between the slider and the movable cavity.

5. A geological disaster crack measuring device as described in claim 1, characterized in that, The striking assembly includes a tube wall extending above the sliding cavity. A ring block extends outward from the top of the tube wall. A second plug plate is vertically slidably connected inside the tube wall. Multiple connecting plates are coaxially fixedly connected to the top of the second plug plate. The multiple connecting plates surround the top of the second plug plate. The second plug plate has a hole at the bottom of the connecting plate. A valve plate is attached to the bottom of the hole. A second rotating rod is fixedly connected to one side of the valve plate. Rotating sleeve blocks are rotatably connected to both ends of the second rotating rod, and two rotating sleeve blocks are fixedly connected to the bottom of the second plug plate.

6. The geological disaster crack measuring device as described in claim 5, characterized in that, Each of the connecting plates has a push rod fixedly connected to its top. The bottom end of the push rod extends into a protrusion that slides against the inner wall of the pipe. A sealing rubber ring is provided at the connection point. A spring is connected between the protrusion and the ring block. The spring is fitted onto the outer wall of the push rod. A connecting pipe is connected to one side of the outer wall of the pipe, and a liquid tank is connected to the other side of the connecting pipe. The liquid tank communicates with the pipe wall via the connecting pipe. One side of the liquid tank is fixedly connected to the outer wall of the pipe, and an opening is fixedly connected to the top of the other side of the liquid tank. A plug is inserted into the opening, and a vent hole is provided at the top of the plug. Liquid is placed in the liquid tank. When the push rod is stretched, the valve plate unfolds, allowing the liquid at the connecting pipe to enter the sliding cavity. When the push rod is pressed down, the valve plate locks and the liquid pushes the plug plate vertically downward.

7. A geological disaster crack measuring device as described in claim 6, characterized in that, The push rod has a semi-circular adjustment groove at its top, and a rotating rod is rotatably connected to the center of the adjustment groove. An adjustment block is fixedly connected to the top of the rotating rod at the adjustment groove, and the top of the adjustment block has a protrusion. A wedge is fixedly connected to the bottom of the rotating rod at the stopper plate. The longitudinal section of the wedge is a right-angled triangle, and the right-angle end is connected to the bottom of the rotating rod. The two sides of the wedge are inclined, which is used to rotate the adjustment block when the push rod is stretched so that the wedge blocks the valve plate, thereby making it easy for the valve plate to not completely block the liquid when the push rod is pressed down.
