[0002] Hydrogeology is the abbreviation of hydrogeology, engineering geology and environmental geology. It is mainly a geological work to investigate and evaluate the geological conditions of groundwater resources, engineering construction and natural environment. Ground fissures are progressive disasters that develop progressively and require continuous observation to prevent sudden changes in the geological environment. In the process of hydrogeology research, it is necessary to use measuring devices to measure the width of geological cracks. The existing method of measuring hydrogeology cracks is usually to manually hold a measuring device and cross both sides of the crack to measure the cracks on the spot.

[0006] Furthermore, the fixed frame includes a fixed plate with one end fixedly connected to the upper end of the mobile frame, a support rod with an upper end fixedly connected to the other end of the fixed plate, and a vertical linear driving member installed on the middle end of the fixed plate, the lower end of the support rod is rotatably connected to the middle end of the scale rod, the driving end of the vertical linear driving member is vertically telescopic, and its driving end is rotated and slidably connected to one end of the scale rod along the length direction of the scale rod.

[0007] Furthermore, a stepped hole is provided on the side wall of the middle end of the scale rod, and one end of the scale rod is rotatably connected to the central axis of the stepped hole, and the other end of the central axis is fixedly connected to the lower end of the support rod.

[0008] Furthermore, a side wall at one end of the scale rod is provided with a transverse slot extending along its length direction, and the scale rod is slidably connected to a force rod having one end adapted and slidably connected to the transverse slot, and the other end of the force rod is rotatably connected to the driving end of the vertical linear driving member.

[0009] Furthermore, the cross section of the scale rod is circular, and the upper ends of the two fixing rods are simultaneously slidably and rotatably connected to the other end of the scale rod.

[0010] Furthermore, the transverse linear drive assembly includes two fixed blocks respectively fixedly connected to the two fixed rods, a bidirectional screw parallel to the scale rod, and a rotating rod one end of which is coaxial and inserted into the bidirectional bolt close to one end of the mobile frame. The threads at both ends of the bidirectional screw have opposite rotation directions and are respectively threadedly connected to the two fixed blocks.

[0011] Furthermore, the transverse linear drive assembly also includes a positioning wheel fixedly connected to the mobile frame, a positioning block with one end slidably connected to the edge end of the positioning wheel, and a positioning rod inserted in the positioning wheel, the central axis of the positioning wheel coincides with the central axis of the scale rod, the sliding trajectory of the positioning block is circular, the dot of the circle coincides with the central axis of the scale rod, the positioning rod is simultaneously inserted in the positioning block, and the other end of the rotating rod is rotatably and slidably connected to the other end of the positioning block.

[0012] Furthermore, the middle end of the bidirectional screw is rotatably connected to a depth measuring assembly, and the depth measuring assembly includes a sleeve rotatably connected to the middle end of the bidirectional screw, a winding wheel installed on the sleeve, a depth measuring rope with one end fixedly connected to the winding wheel, and a weight fixedly connected to the other end of the depth measuring rope, and the depth measuring rope has a length scale.

[0013] Furthermore, the depth measuring assembly also includes a camera installed on the sleeve, and the camera is used to read the scale of the depth measuring rope.

[0014] Furthermore, it also includes an angle measuring device, which is installed on the scale rod.

[0015] The beneficial effects of the present invention are at least:

[0016] The hydraulic geotechnical fracture measuring device enables the entire measuring device to reach one side of the fracture to be measured by moving the mobile frame, and drives the two fixed rods to move oppositely or towards each other relative to the scale rod at the same time through the transverse linear drive component, so that the two measuring rods slide downward relative to the two fixed rods at the same time, and the lower ends of the two measuring rods abut against the inner walls on both sides of the fracture at the same time, so that the width value of the fracture can be read through the scales on the scale rods, thereby improving the technical problem of dangerousness in the manual measurement of the fracture width in the prior art. At the same time, by adopting this measurement method, whether it is for the fracture to be measured with the same height on both sides of the fracture, or for the fracture with inconsistent height on both sides of the fracture, the falling height of the two measuring rods can be directly adjusted by abutting the base plates corresponding to the two measuring rods against the ground, thereby ensuring the level of the measuring rods, solving the problem of uncertain measurement caused by the possible tilt of the measuring rods during measurement in the prior art, so as to improve the technical problem of low accuracy in measuring complex fractures in the prior art.

[0017] The hydraulic ring geological crack measuring device forms two-point limit for the scale rod through the support rod and the vertical linear drive member, so that when the parking place of the mobile frame next to the crack to be measured is an inclined ground, the scale rod is driven by the vertical linear drive member to rotate on the vertical plane with the rotation connection point with the support rod as the midpoint until the scale rod is horizontal, thereby further solving the problem of the measurement uncertainty caused by the possible tilt of the measuring rod during measurement in the prior art, and further improving the technical problem of low accuracy in measuring complex cracks in the prior art.

[0018] The scale rod of the hydraulic ring geological crack measuring device is a round rod. When the parking place of the mobile frame is an inclined plane inclined along the extension direction of the crack, the fixed rod can rotate naturally relative to the scale rod to ensure that the downward sliding measuring rod slides downward accurately and vertically without deviating and measuring other measuring points due to the inclination of the measuring rod, resulting in inaccurate measurement.

The term "vertical" only means that the positional relationship between the parts is more vertical than "parallel", and does not mean that the structure must be completely vertical, but can be slightly tilted.

[0033] See also Figure 1-3 The present invention provides a technical solution: a hydraulic ring geological fracture measuring device, comprising a mobile frame 1, a fixed frame 2 fixed to the mobile frame 1, and a scale rod 3 which is arranged horizontally and one end of which is connected to the lower end of the fixed frame 2, and the other end of the scale rod 3 is provided with a length scale; it also comprises two fixed rods 4, two measuring rods 5, two base plates 6 and a horizontal linear driving component 7 whose driving end is simultaneously connected to the two fixed rods 4, the two fixed rods 4 are both vertically arranged and the upper ends are both slidably connected to the other end of the scale rod 3, the upper ends of the two measuring rods 5 are respectively vertically slidably connected to the lower ends of the two fixed rods 4, the two base plates 6 are both parallel to the scale rod 3, and the facing ends are respectively fixedly connected to the opposite sides of the two measuring rods 5, and the horizontal linear driving component 7 is used to drive the two fixed rods 4 to move toward or away from each other at the same time.

[0034] During measurement, the entire measuring device is moved to one side of the crack to be measured by moving the movable frame 1, so that the scale rod 3 is initially placed horizontally above the crack, and then the two fixed rods 4 are driven to slide simultaneously along the length direction of the scale rod 3 by the transverse linear drive component 7. At the same time, the two fixed rods 4 are driven to move simultaneously away from or towards each other by the transverse linear drive component 7 until the other ends of the two substrates 6 are respectively approximately located above the two sides of the crack to be measured, and then the two measuring rods 5 are simultaneously slid downward relative to the two fixed rods 4 until the two substrates 6 respectively abut against the two sides of the crack to be measured, and then the two fixed rods 4 are driven to slide simultaneously along the length direction of the scale rod 3 by the transverse linear drive component 7 until the lower ends of the two measuring rods 5 abut against the inner walls on both sides of the crack at the same time (in this process, when the lower end of one of the measuring rods 5 first abuts against one side of the crack, under the reaction force, the fixed rod 4 corresponding to the other measuring rod 5 slides relative to the scale rod 3 until the lower ends of the two measuring rods 5 abut against the inner walls on both sides of the crack at the same time The inner wall on both sides of the crack), at this time, the width value of the crack can be read through the scale on the scale rod 3. Through this measurement method, the measurement personnel only need to measure on one side of the crack, and do not need to cross both sides, which is relatively safe, and there is no need to hold the scale rod 3 for measurement, which reduces the problem of inaccurate measurement of the scale rod 3 due to the tilt when measuring with the scale rod 3 held in hand, and improves the technical problem of dangerousness in the method of manually measuring the width of the crack in the prior art; and by adopting this measurement method, whether it is for the crack to be measured with the same height on both sides of the crack, or for the crack to be measured with inconsistent height on both sides of the crack and the existence of "high and low shoulders", the two measuring rods 5 can directly adjust the falling height of the two measuring rods 5 in the process of falling, by the substrate 6 corresponding to the two measuring rods 5 abutting against the ground, so as to ensure the level of the scale rod 3, solve the problem of the scale rod 3 possibly tilting during measurement in the prior art and causing measurement uncertainty, so as to achieve the improvement of the technical problem of low accuracy in measuring complex cracks in the prior art.

[0035] Through the above-mentioned measuring method, during the measuring process, the two substrates 6 are respectively abutted against the ground on both sides of the crack to be measured, forming a limiting effect on the downward sliding of the measuring rod 5, ensuring that the measuring rod 5 slides adaptively, so that the assembly of the measuring rod 5 and the fixed rod 4 is extended or shortened to an appropriate length. At the same time, the horizontal state of the scale rod 3 can be judged by the abutment angle state of the substrate 6 and the ground.

[0036] In this embodiment, the mobile frame 1 includes a frame 11, a plurality of wheels 12 fixedly mounted on the frame 11, and a stand 13 whose lower end is fixedly connected to the frame 11. The fixed frame 2 is fixed to the stand 13 of the mobile frame 1; the scale rod 3 extends horizontally in a direction perpendicular to the stand 13.

[0037] When the entire measuring device is moved, the frame 11 can be pushed or pulled to achieve movement.

[0038] The wheel 12 may be a universal wheel. When the wheel 12 is moved into position and the measurement operation is performed, the wheel 12 is braked to ensure the stability of the measuring device during measurement.

[0039] On the basis of the above embodiment, a counterweight 14 is installed on the frame 11 , and the counterweight 14 and the scale rod 3 are placed on both sides of the stand 13 to ensure the stability of the frame 11 .

[0040] On the basis of the above embodiment, a vertical card slot 41 is provided on one side of the two fixing rods 4. The cross section of the vertical card slot 41 is stepped, and the vertical card slot 41 passes downward through the lower side of the fixing rod 4. A vertical card block 51 adapted to and vertically slidably connected to the vertical card slot 41 is fixed to the side wall of the measuring rod 5. The sliding connection between the measuring rod 5 and the fixing rod 4 is achieved by the vertical card block 51 being clamped in the vertical card slot 41.

[0041] A limiting groove 42 is provided at the bottom of the vertical slot 41, and a limiting block 52 adapted to and slidably connected to the limiting groove 42 is fixed to the upper end of the vertical block 51. When the vertical block 51 vertically slides downward to connect to the vertical slot 41, the limiting block 52 synchronously slides in the limiting groove 42, and when the limiting block 52 abuts against the bottom of the limiting groove 42, the measuring rod 5 stops sliding relative to the fixing rod 4, thereby preventing the measuring rod 5 from being separated from the fixing rod 4 through the limiting of the vertical slot 41 and the limiting groove 42.

[0042] See also Figure 1-2 In this embodiment: the fixed frame 2 includes a fixed plate 21 with one end fixedly connected to the upper end of the mobile frame 1, a support rod 22 with an upper end fixedly connected to the other end of the fixed plate 21, and a vertical linear driving member 23 installed at the middle end of the fixed plate 21, the lower end of the support rod 22 is rotatably connected to the middle end of the scale rod 3, the driving end of the vertical linear driving member 23 is vertically telescopic, and its driving end rotates and slides along the length direction of the scale rod 3 to be connected to one end of the scale rod 3.

[0043] The scale rod 3 is balanced by the support rod 22 and the vertical linear drive member 23. The scale rod 3 is connected to the support rod 22 and the vertical linear drive member 23 to form two-point limit positions, so as to ensure the balance of the scale rod 3. The rotation connection point between the support rod 22 and the scale rod 3 is used as a fulcrum, and the extension and contraction of the driving end of the vertical linear drive member 23 is used to make the scale rod 3 rotate on the vertical plane with the rotation connection point with the support rod 22 as the midpoint, so as to ensure the levelness of the scale rod 3. Specifically, when the parking place of the mobile frame 1 next to the crack to be measured is flat, the support rod 22 and the vertical linear drive member 23 are respectively at the same height with the two connection positions formed by the scale rod 3. At this time, the scale rod 3 is in a horizontal state, and the two fixed rods 4 can be directly driven to move by the horizontal linear drive assembly 7, and the subsequent crack width measurement operation can be carried out. When the parking place of the mobile frame 1 next to the crack to be measured is an inclined ground, since the mobile frame 1 parked next to the crack to be measured is in an inclined state, the initial state of the scale rod 3 is an inclined state. At this time, the vertical linear drive member 23 can be started, and the scale rod 3 is driven by the vertical linear drive member 23 to rotate on the vertical plane with the rotation connection point with the support rod 22 as the midpoint until the scale rod 3 is horizontal, and subsequent measurement operations can be carried out; through this measurement method, the present device can perform measurement operations at the inclined ground where the crack is measured, and can ensure that the scale rod 3 remains horizontal during the measurement process, thereby further solving the problem in the prior art that the scale rod 3 may tilt during measurement and cause measurement uncertainty, so as to further improve the technical problem of low accuracy in measuring complex cracks in the prior art.

[0044] In this embodiment, one end of the fixing plate 21 is fixedly connected to the upper end of the upright frame 13 of the movable frame 1 .

[0045] The vertical linear drive member 23 is disposed between the support rod 22 and the stand 13 , and may be an electric cylinder or a pneumatic cylinder, the cylinder body being fixedly connected to the fixed plate 21 , and the drive end thereof being vertically retractable.

[0046] See also Figure 4-6 In this embodiment: a stepped hole 31 is opened on the side wall of the middle end of the scale rod 3, and the scale rod 3 is rotatably connected to a central axis 221 with one end adapted and rotatably connected to the stepped hole 31, and the other end of the central axis 221 is fixedly connected to the lower end of the support rod 22.

[0047] The scale rod 3 is suspended and installed by the support rod 22 through the connection of the central axis 221, and when the angle of the scale rod 3 is adjusted by the drive of the vertical linear drive member 23, the scale rod 3 rotates in the vertical plane with the central axis 221 as the center. When the driving end of the vertical linear drive member 23 stops extending and retracting, the scale rod 3 remains stationary and balanced under the connection of the central axis 221.

[0048] The central axis 221 is arranged perpendicular to the scale rod 3 and the support rod 22 .

[0049] As one of the parallel solutions of this embodiment, one end of the central shaft 221 is adapted and rotatably connected to the stepped hole 31 , and the other end is rotatably connected to the lower end of the support rod 22 .

[0050] As the second parallel solution of this embodiment, one end of the central axis 221 is fixedly connected to the middle end of the scale rod 3 , and the other end is rotatably connected to the lower end of the support rod 22 .

[0051] In this embodiment: a side wall at one end of the scale rod 3 is provided with a transverse slot 32 extending along its length direction, and the scale rod 3 is slidably connected to a force rod 231 whose one end is adapted and slidably connected to the transverse slot 32, and the other end of the force rod 231 is rotatably connected to the driving end of the vertical linear driving member 23.

[0052] When the inclination angle of the scale rod 3 is adjusted by extending and retracting the driving end of the vertical linear driving member 23 so that the scale rod 3 returns to a horizontal state, the force rod 231 rotates relative to the driving end of the vertical linear driving member 23 and slides along the transverse slot 32 relative to the scale rod 3.

[0053] The cross section of the transverse slot 32 is in a stepped or dovetail shape.

[0054] As one of the parallel solutions of this embodiment, the transverse slot 32 is a stepped slot. One end of the force rod 231 is stepped and has a circular cross section, and is rotatably connected to the transverse slot 32. In the process of adjusting the inclination angle of the scale rod 3, the force rod 231 can rotate relative to the scale rod 3. In this embodiment, the other end of the force rod 231 is rotatably or fixedly connected to the driving end of the vertical linear drive member 23.

[0055] See also Figure 1-3 In this embodiment, the cross section of the scale rod 3 is circular, and the upper ends of the two fixed rods 4 are simultaneously slidably and rotatably connected to the other end of the scale rod 3.

[0056] During the measurement process, when the entire measuring device reaches one side of the crack to be measured through the movement of the mobile frame 1, and the scale rod 3 is initially placed horizontally above the crack, the two fixed rods 4 can be simultaneously rotated with the scale rod 3 as the central axis by applying force to the transverse linear drive component 7, until the two fixed rods 4 are in an upward tilted state, or even rotated 180°, so that the measuring rod 5 is on the upper side relative to its corresponding fixed rod 4. At this time, the measuring rod 5 can be prevented from contacting the ground due to natural downward sliding, thereby ensuring that the scale rod 3 is suspended and smoothly moves to the top of the crack to be measured. Afterwards, the two fixed rods 4 are driven to move back or toward each other at the same time by the transverse linear drive component 7, until the other ends of the two substrates 6 are respectively approximately located above the two sides of the crack to be measured. Thereafter, the two fixed rods 4 are At the same time, the scale rod 3 is rotated in the opposite direction with the scale rod 3 as the central axis, and then the two measuring rods 5 are in a vertical state and slide downward relative to the two corresponding fixed rods 4 at the same time, until the two base plates 6 are respectively in contact with the two sides of the crack to be measured, and then the subsequent measurement operation can be carried out; through the above-mentioned measurement method, when the parking place of the mobile frame 1 is an inclined plane inclined along the extension direction of the crack, under the action of gravity, the fixed rod 4 can rotate naturally relative to the scale rod 3 to ensure that the downward sliding measuring rod 5 accurately slides vertically downward and measures the measured point without deviating and measuring other measuring points due to the inclination of the measuring rod 5, resulting in inaccurate measurement (not only the measuring point is inaccurate, but also the ground at the actual measuring point may be in a different inclination state, resulting in the horizontal scale rod 3 being inclined relative to the actual measuring point, and the actual measurement data is inaccurate).

[0057] There are a plurality of length scales circumferentially arranged on the scale rod 3 , so that when the fixed rod 4 rotates at any angle relative to the scale rod 3 , the distance between the two fixed rods 4 can be intuitively connected through the length scales.

[0058] See also Figure 1-6 In this embodiment: the transverse linear drive assembly 7 includes two fixed blocks 71 respectively fixedly connected to the two fixed rods 4, a bidirectional screw 72 parallel to the scale rod 3, and a rotating rod 73 with one end coaxial and plugged into the bidirectional screw 72 close to one end of the mobile frame 1. The two ends of the bidirectional screw 72 have opposite thread rotation directions and are respectively threadedly connected to the two fixed blocks 71.

[0059] When the two fixed rods 4 are driven to move away from or towards each other at the same time by the transverse linear drive assembly 7, a torque is applied to the other end of the rotating rod 73 to rotate the bidirectional screw 72. Under the limiting action of the scale rod 3 which remains stationary, the two fixed rods 4 can slide away from or towards each other relative to the scale rod 3 at the same time. In this process, the two fixed rods 4 can be pushed to move in the same direction relative to the scale rod 3 at the same time by applying a thrust or a pull to the other end of the rotating rod 73, until the other ends of the two substrates 6 are respectively approximately directly above the two sides of the crack to be measured, so as to achieve a quick adjustment effect. When the force applied to the rotating rod 73 is stopped, the two fixed rods 4 maintain a constant distance under the connection of the bidirectional screw 72.

[0060] The other end of the rotating rod 73 extends in the direction of the movable frame 1 to facilitate the measurement personnel to operate it.

[0061] The fixing block 71 is fixedly connected to a side of the fixing rod 4 facing away from the vertical slot 41 .

[0062] A polygonal hole is formed at one end of the bidirectional screw rod 72, and one end of the rotating rod 73 is adapted to and inserted into the polygonal hole.

[0063] In this embodiment: the transverse linear drive assembly 7 also includes a positioning wheel 74 fixedly connected to the mobile frame 1, a positioning block 75 with one end slidably connected to the edge end of the positioning wheel 74, and a positioning rod 76 inserted in the positioning wheel 74. The central axis of the positioning wheel 74 coincides with the central axis of the scale rod 3, the sliding trajectory of the positioning block 75 is circular, the dot of the circle coincides with the central axis of the scale rod 3, the positioning rod 76 is also inserted in the positioning block 75, and the other end of the rotating rod 73 is rotated and slidably connected to the other end of the positioning block 75.

[0064] In the process of pushing the mobile frame 1 to move the entire measuring device, and in the process of making the entire measuring device reach one side of the crack to be measured by the movement of the mobile frame 1, and making the scale rod 3 initially placed horizontally above the crack, the two fixed rods 4 can be simultaneously rotated with the scale rod 3 as the central axis by applying force to the other end of the rotating rod 73, until the two fixed rods 4 are in an upward tilted state, or even rotated 180°, so that the measuring rod 5 is on the upper side relative to its corresponding fixed rod 4, at this time, the measuring rod 5 can be prevented from contacting the ground due to natural downward sliding; in the process of the two fixed rods 4 simultaneously rotating with the scale rod 3 as the central axis, the positioning rod 76 is first pulled out of the positioning block 75, so that the positioning block 75 rotates relative to the positioning wheel 74, and after rotating into place, the positioning rod 76 is simultaneously inserted into the positioning wheel 74 and the positioning block 75, which can ensure the height of the rotating rod 73, and then ensure that the two fixed rods 4 are always in an upward tilted state, which is convenient for the movement of the entire measuring device.

[0065] Of course, when the measurement is completed, force can be applied to the other end of the rotating rod 73 until the two fixed rods 4 are in an upward tilted state, so that the vertical measuring rod 5 with the lower end entering and abutting against the inner wall of the crack can rotate with the scale rod 3 as the central axis and directly rotate out of the crack.

[0066] The positioning wheel 74 is fixedly connected to the stand 13 of the mobile frame 1 .

[0067] A round hole is formed through the other end of the positioning block 75 , and the rotating rod 73 is a round rod to achieve a rotating and sliding connection with the positioning block 75 .

[0068] An annular groove 741 is provided at the edge end of the positioning wheel 74, and the central axis of the annular groove 741 coincides with the central axis of the scale rod 3. The cross-section of the annular groove 741 is stepped or dovetail-shaped. One end of the positioning block 75 is adapted and slidably connected to the annular groove 741 to realize the rotational connection between the positioning block 75 and the positioning wheel 74.

[0069] The edge of the positioning wheel 74 is also provided with a plurality of insertion holes 742, which are distributed in a circular pattern with the axis of the positioning wheel 74 as the center. A positioning hole 751 is provided at one end of the positioning block 75, and the positioning hole 751 can be connected to any insertion hole 742 by rotating the positioning block 75. The positioning rod 76 is adapted to the insertion hole 742 and the positioning hole 751.

[0070] When the two fixing rods 4 rotate with the scale rod 3 as the central axis at the same time, the positioning rod 76 is first pulled out of the positioning block 75 so that the positioning block 75 rotates into place relative to the positioning wheel 74. Then, the positioning rod 76 can be inserted into the connected jack 742 and the positioning hole 751 at the same time to ensure that the two fixing rods 4 are always in an upward tilted state, which facilitates the movement of the entire measuring device.

[0071] See also Figure 4-7 In this embodiment: the middle end of the bidirectional screw 72 is rotatably connected to a depth measuring assembly 8, and the depth measuring assembly 8 includes a sleeve 81 rotatably connected to the middle end of the bidirectional screw 72, a winding wheel 82 installed on the sleeve 81, a depth measuring rope 83 with one end fixedly connected to the winding wheel 82, and a weight 84 fixedly connected to the other end of the depth measuring rope 83, and the depth measuring rope 83 has a length scale.

[0072] While the lower ends of the two measuring rods 5 are simultaneously in contact with the inner walls on both sides of the crack to read the width of the crack through the scale on the scale rod 3, a weight 84 can be lowered through the winding wheel 82. When the weight 84 touches the bottom, the depth of the crack can be read through the depth measuring rope 83, thereby completing the depth measurement operation simultaneously.

[0073] In the process of measuring the width, since the lower ends of the two measuring rods 5 are in contact with the inner walls on both sides of the crack at the same time, and the weight 84 is always in the middle position of the two fixed rods 4, the weight 84 is relatively guaranteed to fall from the middle position of the crack, which can reduce the problem of the weight 84 touching the inner wall of the crack during the falling process, thereby affecting the accuracy of the crack depth measurement.

[0074] When adjusting the position of the fixing rod 4 so that the measuring rod 5 reaches the specified position and performing the crack width measurement operation, under the action of the gravity of the weight 84, the sleeve 81 always adaptively rotates relative to the bidirectional screw 72 until the weight 84 is always down and the weight 84 is always in the middle position between the two fixing rods 4.

[0075] Among them, a motor 811 is fixedly connected to the sleeve 81, and the output shaft of the motor 811 is coaxially fixedly connected to one end of the winding wheel 82, so that the winding wheel 82 is driven to rotate by the motor 811 to realize the unwinding and winding operations of the depth measuring rope 83.

[0076] In this embodiment, the depth measuring assembly 8 further includes a camera 85 installed on the sleeve 81 , and the camera 85 is used to read the scale of the depth measuring rope 83 .

[0077] In the process of measuring the depth of the crack by the depth measuring rope 83, the scale value of the depth measuring rope 83 can be read by the camera 85 at all times, and the frequency of data changes can be used to determine whether the weight 84 touches the inner wall of the crack and whether it touches the bottom during the falling process. When the weight 84 is falling, if the scale of the depth measuring rope 83 changes suddenly within a certain time unit, it can be determined that the falling of the weight 84 is affected.

[0078] See also Figure 1-2 In this embodiment: the hydraulic ring geological fracture measuring device described in the present invention also includes an angle measuring device 9, and the angle measuring device 9 is installed on the scale rod 3.

[0079] During the measurement process, the inclination angle of the scale rod 3 can be determined by the angle measuring device 9 to ensure that the scale rod 3 remains horizontal when reading the width data value.

[0080] As one of the parallel solutions of this embodiment, the angle measuring device 9 can be a bubble level. The length direction of the bubble level extends along the length direction of the scale rod 3. The level of the scale rod 3 is judged by the centering of the bubble of the bubble level.

[0081] As one of the parallel schemes of this embodiment, the angle measuring device 9 includes an inclination sensor or a horizontal sensor installed on the scale rod 3, and a control system (such as a single-chip microcomputer, a PLC) is arranged on the frame 11. The control system signal is connected to the vertical linear drive member 23, so that when the scale rod 3 is tilted, the angle measuring device 9 transmits the information of the tilt angle to the control system, and the control system calculates the telescopic length of the vertical linear drive member 23 that needs to be adjusted according to the tilt angle. The control system outputs a control signal to the control system of the vertical linear drive member 23, and the vertical linear drive member 23 is telescoped and adjusted according to the control signal, so that through continuous feedback and adjustment, the scale rod 3 returns to a horizontal state.

[0082] Working principle: When the hydraulic ring geological fracture measuring device of the present invention needs to be moved, the frame 11 can be directly pushed to realize the movement of the entire device; during this process, the measuring rod 5 is in a downward moving state relative to the fixed rod 4. Or, by applying force to the other end of the rotating rod 73, the two fixed rods 4 are simultaneously rotated with the scale rod 3 as the central axis until the two fixed rods 4 are in an upward tilted state, so that the measuring rod 5 is on the upper side relative to its corresponding fixed rod 4. After rotating in place, the positioning rod 76 is inserted into the positioning wheel 74 and the positioning block 75 at the same time to ensure the height of the rotating rod 73, thereby ensuring that the two fixed rods 4 are always in an upward tilted state. At this time, the measuring rod 5 can be prevented from contacting the ground due to natural downward sliding, so as to realize the movement of the entire device.

[0083] Measuring method a: During measurement, when the parking area of ​​the mobile frame 1 next to the crack to be measured is flat, the entire measuring device is moved to one side of the crack to be measured by moving the mobile frame 1, so that the scale rod 3 is initially placed horizontally just above the crack, and then by applying a thrust or a pull to the other end of the rotating rod 73, the two fixed rods 4 are pushed or pulled to slide along the length direction of the scale rod 3 at the same time. At the same time, by applying a torque to the other end of the rotating rod 73, the bidirectional screw 72 is rotated to drive the two fixed rods 4 to move away from or towards each other at the same time. Move until the other ends of the two substrates 6 are roughly located above the two sides of the crack to be measured, and then make the two measuring rods 5 slide downward relative to the two fixed rods 4 at the same time, until the two substrates 6 respectively abut against the two sides of the crack to be measured, and then, by applying torque to the other end of the rotating rod 73, the bidirectional screw 72 is rotated to drive the two fixed rods 4 to slide oppositely along the length direction of the scale rod 3 at the same time, until the lower ends of the two measuring rods 5 abut against the inner walls on both sides of the crack. At this time, the width value of the crack can be read through the scale on the scale rod 3.

[0084] Measuring method b: During measurement, when the parking place of the mobile frame 1 located next to the crack to be measured is an inclined ground, the ground where the parking place is located is inclined downward or upward relative to the crack, and the entire measuring device is moved to one side of the crack to be measured by moving the mobile frame 1, so that the scale rod 3 is initially placed horizontally just above the crack, and then the vertical linear drive member 23 is started, and the scale rod 3 is driven by the vertical linear drive member 23 to rotate on the vertical plane with the rotation connection point with the support rod 22 as the midpoint until the scale rod 3 is horizontal (at this time, the bidirectional screw 72 is horizontal, and the rotating rod 73 is inclined, and the rotating rod 73 can be pulled out of the bidirectional screw 72 first), and then the two fixed rods 4 are pushed or pulled simultaneously along the scale rod 3 by applying a thrust or a pull to the other end of the rotating rod 73 The measuring rod 3 slides in the length direction, and at the same time, by applying torque to the other end of the rotating rod 73, the bidirectional screw 72 is rotated to drive the two fixed rods 4 to move away from or towards each other at the same time, until the other ends of the two substrates 6 are roughly located directly above the two sides of the crack to be measured, and then the two measuring rods 5 slide downward relative to the two fixed rods 4 at the same time, until the two substrates 6 respectively abut against the two sides of the crack to be measured, and then, by applying torque to the other end of the rotating rod 73, the bidirectional screw 72 is rotated to drive the two fixed rods 4 to slide away from each other along the length direction of the measuring rod 3 at the same time, until the lower ends of the two measuring rods 5 abut against the inner walls on both sides of the crack at the same time, at this time, the width value of the crack can be read through the scale on the measuring rod 3.

[0085] Measurement method c: During measurement, when the parking place of the movable frame 1 is an inclined plane inclined along the extending direction of the crack, the measurement method is the same as the measurement method when the parking place is a flat ground.

[0086] Measuring method d: During measurement, when the parking place of the mobile frame 1 is an inclined plane inclined along the extension direction of the crack, and the ground where the parking place is located is an inclined plane inclined downward or upward relative to the crack, the measuring method a and the measuring method b can be used in combination.

[0087] For the above-mentioned measuring method, in order to facilitate the entire measuring device to reach one side of the crack to be measured by moving the mobile frame 1, so that the scale rod 3 is initially placed horizontally just above the crack, the positioning rod 76 can be first pulled out of the positioning block 75, and by applying torque to the other end of the rotating rod 73, the bidirectional screw 72 is rotated, so that the two fixed rods 4 are simultaneously rotated with the scale rod 3 as the central axis, until the two fixed rods 4 are in an upwardly tilted state, so that the measuring rod 5 is on the upper side relative to its corresponding fixed rod 4.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
