Description

[0002] Channel slope crack monitoring equipment is a tool used to monitor and analyze cracks in channel slope structures. Crack meters are generally used to monitor the development of cracks. They can be mechanical, electronic or digital. Mechanical crack meters physically measure the width of the cracks, while electronic or digital crack meters use sensors and data recording devices to provide more accurate and real-time measurements.

[0003] When installing a crack meter, the two sides of the crack meter are generally fixed above the ground on both sides of the crack. When the crack width changes, since the crack meter is in a telescopic state, one end of the crack meter will extend or shorten, and the internal sensor will record the change result. In some existing technologies, the two sides of the crack meter are only fixed to the ground of the channel slope through a set of support rods and bolts. Since the channel slope is inclined, the stability of one support rod is poor.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] like Figures 1 to 9 As shown, the present invention provides a channel slope crack monitoring device, including a connecting plate 1, a crack meter 3 is provided on the bottom outer wall of the connecting plate 1 through a mounting mechanism 2, and a supporting mechanism 5 is provided on the bottom outer wall of the connecting plate 1 through a connecting mechanism 4; the supporting mechanism 5 includes a fixing rod 501, a round rod 502 is fixedly connected to the bottom outer wall of the fixing rod 501, a slot 503 is provided on the outer wall of the round rod 502, a slider 507 is slidably connected to the outer wall of the round rod 502, the outer wall of the slider 507 is hinged to the support rod 505 through a hinge rod 504, the bottom outer wall of the support rod 505 is hinged to a bottom plate 506, and the inner wall of the slider 507 is elastically connected to a pull rod 508 through a connecting spring 509.

[0035] The above scheme is adopted: the crack meter 3 is an existing technology, which is an instrument specially used to measure the change of the width of the channel slope crack. The two ends of the crack meter 3 are respectively installed under the connecting plates 1 on both sides through two sets of mounting mechanisms 2. The connecting plates 1 on both sides are fixed on the corresponding supporting mechanisms 5 through the connecting mechanisms 4. The two sets of supporting mechanisms 5 are fixed to the two ends of the crack by bolts. The crack meter 3 spans the crack. When the crack width changes, the supporting mechanisms 5 on both sides move with the ground on both sides of the crack. The sensors in the crack meter 3 can monitor the crack changes and transmit signals. To the operator; the support rods 505 in the support mechanism 5 are provided with three groups, and the three groups of support rods 505 can be folded and unfolded. After unfolding, the bottom plate 506 is fixed to the ground on both sides of the crack by bolts, which can make the fixing effect more stable, and after folding, it can save space, which is convenient for the operator to carry and transport; the slots 503 on the round rod 502 are provided with upper and lower groups. When the pull rod 508 in the slider 507 is engaged with the lower slot 503, the support rod 505 is unfolded, and when the pull rod 508 is engaged with the upper slot 503, the support rod 505 is folded.

[0036] like Figures 1 to 3 As shown, one end of the hinged rod 504 is hinged to the inner wall of the support rod 505, and the other end of the hinged rod 504 is hinged to the outer wall of the slider 507, and the support rod 505 is hinged to the outer wall of the fixed rod 501; one end of the connecting spring 509 is fixedly connected to the outer wall of the pull rod 508, and the other end of the connecting spring 509 is fixedly connected to the inner wall of the slider 507, the outer wall of the pull rod 508 is slidably connected to the inner wall of the slider 507, and the pull rod 508 is engaged with the slot 503.

[0037] The above scheme is adopted: by pulling the pull rod 508 outward to make it disengage from a group of slots 503, the connecting spring 509 is forced to shrink, and the limit of the slider 507 can be released, and the slider 507 can be moved up and down; when the slider 507 is moved downward, the hinge rod 504 is driven to flip, and the outer end of the hinge rod 504 lifts the support rod 505 to flip the support rod 505, so that the three groups of support rods 505 can be unfolded at the same time. When the slider 507 moves to the position where the pull rod 508 corresponds to the position of the lower group of slots 503, the connecting spring 509 moves the pull rod 508 to reset due to the elastic force , the pull rod 508 is engaged with the card slot 503, so that the position of the slider 507 can be fixed, thereby fixing the three groups of support rods 505; after the fixing is completed, the bottom plate 506 can be rotated to make it contact with the ground, and the support mechanism 5 can be installed by bolts, and the three groups of support rods 505 have a better supporting effect. Since the channel slope is generally in an inclined state, the crack meter 3 can be more stable; when the support mechanism 5 needs to be folded up for carrying and transportation, the pull rod 508 can be pulled outward and the slider 507 can be moved upward, thereby driving the three groups of support rods 505 to be folded up through the hinged rod 504, which saves more space.

[0038] like Figures 4 to 6As shown, the mounting mechanism 2 includes a mounting block 201, the inner wall of the mounting block 201 is elastically connected to a concave plate 206 via a reset spring 209, the outer wall of the concave plate 206 is provided with a through groove 203, the inner wall of the mounting block 201 is slidably connected to a baffle 205, the outer wall of the baffle 205 is fixedly connected to a sliding rod 204, the top outer wall of the crack meter 3 is fixedly connected to a fixed block 202, and the inner wall of the fixed block 202 is elastically connected to a baffle 208 via a telescopic spring 207.

[0039] By adopting the above scheme: the crack meter 3 can be conveniently and quickly installed under the connecting plate 1 through the installation mechanism 2. Two groups of blocks 208 and telescopic springs 207 are provided in the fixed block 202, which are symmetrically distributed on the inner walls on both sides of the fixed block 202. When installing the crack meter 3, the fixed block 202 above the crack meter 3 can be made to correspond to the opening position below the mounting block 201, and the fixed block 202 can be inserted into the mounting block 201. The arc surface of the block 208 is squeezed by the inner wall of the mounting block 201, so that the block 208 moves to the inner wall of the fixed block 202, and the telescopic spring 207 is forced to shrink. When the fixed block 202 moves to the position where the block 208 corresponds to the internal groove of the mounting block 201, the elastic force of the telescopic spring 207 causes the block 208 to pop out and engage with the groove, so that the fixed block 202 can be fixed in the mounting block 201, and the fixation of the crack meter 3 is completed.

[0040] like Figures 4 to 6 As shown, the mounting block 201 is fixedly connected to the outer wall of the bottom end of the connecting plate 1, the fixed block 202 contacts the inner wall of the mounting block 201, and the sliding rod 204 is slidably connected to the inner wall of the through groove 203; one end of the return spring 209 is fixedly connected to the outer wall of the concave plate 206, and the other end of the return spring 209 is fixedly connected to the inner wall of the mounting block 201, and the outer wall of the concave plate 206 is slidably connected to the inner wall of the mounting block 201; one end of the telescopic spring 207 is fixedly connected to the outer wall of the stopper 208, and the other end of the telescopic spring 207 is fixedly connected to the inner wall of the fixed block 202, the outer wall of the stopper 208 is slidably connected to the inner wall of the fixed block 202, and the stopper 208 is clamped with the inner wall of the fixed block 202.

[0041] The above scheme is adopted: by pressing the concave plate 206, the return spring 209 is forced to shrink. When the concave plate 206 moves, the inner wall of the through groove 203 squeezes the sliding rod 204, so that the sliding rod 204 moves along the inner wall of the through groove 203, driving the baffle 205 to move synchronously. Since the baffle 205 is slidably connected to the inner wall of the mounting block 201, the baffle 205 can only move horizontally downward; when the fixed block 202 is installed in the mounting block 201, the outer wall of the baffle 205 is connected to the fixed block 201. 02 is flush with the outer wall and is in the groove of the inner wall of the mounting block 201. When the baffle 205 moves downward, it squeezes the arc surface of the block 208, so that the block 208 moves inward along the inner wall of the fixing block 202 and breaks away from the groove of the inner wall of the mounting block 201. The limit of the fixing block 202 can be released, and the fixing block 202 can be taken out to complete the disassembly of the crack meter 3. Thereby, there is no need to install and disassemble the crack meter 3 by turning the bolts multiple times, which is more convenient and quick, and improves work efficiency.

[0042] like Figures 7 to 9 As shown, the connecting mechanism 4 includes a connecting block 401, the inner wall of the connecting block 401 is elastically connected to a turntable 403 through a spiral spring 402, the bottom outer wall of the turntable 403 is fixedly connected to a rotating shaft 407, the outer wall of the turntable 403 is provided with an inclined groove 404, the inner wall of the inclined groove 404 is slidably connected to an L-shaped rod 405, and the outer wall of the L-shaped rod 405 is fixedly connected to a wedge 406; the connecting block 401 is plugged into the inner wall of the bottom end of the connecting plate 1, the connecting block 401 is fixedly connected to the top outer wall of the fixing rod 501, one end of the spiral spring 402 is fixedly connected to the outer wall of the turntable 403, the other end of the spiral spring 402 is fixedly connected to the inner wall of the connecting block 401, the rotating shaft 407 is rotatably connected to the inner wall of the connecting block 401, and the wedge 406 is slidably connected to the inner wall of the connecting block 401.

[0043] The above scheme is adopted: the connection mechanism 4 is arranged above the fixing rod 501, and the fixing rod 501 can be installed below the connecting plate 1 through the connection mechanism 4. The wedge block 406 and the L-shaped rod 405 are provided with two groups, which are symmetrically distributed in the inner walls of both sides of the connecting block 401. The inclined groove 404 is also provided with two groups. The outer wall of the rotating disk 403 is provided with a protrusion, which penetrates the outer wall of the connecting block 401. The rotating disk 403 and the rotating shaft 407 can be driven to rotate by turning the protrusion, and the spiral spring 402 is stretched by force. When the turntable 403 rotates, the inner wall of the inclined groove 404 squeezes the L-shaped rod 405, so that the L-shaped rod 405 drives the wedge block 406 to move. Since the wedge block 406 is slidably connected to the inner wall of the connecting block 401, it is in a lateral moving state when moving. Therefore, by rotating the turntable 403, the two groups of wedge blocks 406 can be moved to the middle at the same time, so that the wedge blocks 406 are out of contact with the limiting groove 6, and the limiting of the connecting block 401 can be released, and the connecting mechanism 4 and the supporting mechanism 5 can be removed from the bottom of the connecting plate 1.

[0044] When installing the support mechanism 5, the operator can align the connecting block 401 with the opening position below the connecting plate 1, and insert the connecting block 401 upwards. At this time, the arc surface of the wedge block 406 is squeezed by the outer wall below the connecting plate 1, and moves to the inner wall of the connecting block 401, driving the L-shaped rod 405 to move synchronously. The L-shaped rod 405 squeezes the inner wall of the inclined groove 404, so that the rotating disk 403 moves, and the spiral spring 402 is forced to shrink; when the connecting block 401 moves to the position where the wedge block 406 and the limiting groove 6 are Correspondingly, the volute spring 402 drives the turntable 403 to rotate in the opposite direction due to its own elastic force, and the inclined groove 404 drives the L-shaped rod 405 to move, so that the two sets of wedge blocks 406 move synchronously to both sides, and the connecting block 401 can be fixed in the inner wall below the connecting plate 1 to complete the assembly; thereby, the support mechanism 5, the connecting plate 1 and the crack meter 3 can be conveniently and quickly assembled when in use, and the support mechanism 5, the connecting plate 1 and the crack meter 3 can be disassembled and transported separately when they need to be carried and transported, which saves space and is easy to carry.

[0045] The present application also proposes a monitoring method for channel slope crack monitoring equipment, comprising the following steps:

[0046] S1. According to the monitoring requirements, select a suitable crack position and install the crack meter 3 to ensure that the installation position is stable and will not be disturbed by external factors. Install the support mechanism 5 on both sides of the crack, and install the connecting plate 1 on the connecting mechanism 4 above the support mechanism 5, and install the crack meter 3 below the connecting plate 1 to complete the overall assembly;

[0047] S2, start the crack meter 3 and start collecting crack width data. The crack meter 3 will monitor the changes of the cracks in real time and transmit the data to the data acquisition device or monitoring system. After receiving the data transmitted by the crack meter 3, the data acquisition device or monitoring system will process and analyze the data and display it in the form of charts, reports, etc.;

[0048] S3. Monitor cracks regularly at certain time intervals. For important cracks or cracks that change rapidly, continuous monitoring methods can be used to detect changes in cracks in a timely manner.

[0049] The working principle and use process of the present invention:

[0050] The crack meter 3 is installed under the connecting plate 1 through the installing mechanism 2. The connecting plates 1 on both sides are connected to the supporting mechanism 5 through the connecting mechanism 4. The supporting mechanism 5 is fixed to the ground on both sides of the crack by bolts. The crack meter 3 spans the crack and is used to monitor the change of the width of the crack in the channel slope. It is a prior art. When fixing the supporting mechanism 5, the operator can first pull the pull rod 508 outward to make it disengage from the upper slot 503, and the connecting spring 509 is forced to shrink, releasing the limit of the slider 507, and then the slider 507 is moved downward to drive the hinged rod 504 to flip, and the outer end of the hinged rod 504 lifts the supporting rod 505 to make the supporting rod 505 flip and unfold. When the slider 507 moves to the position where the pull rod 508 corresponds to the position of a group of slots 503 below, the connecting spring 509 moves the pull rod 508 to reset due to the elastic force, and the pull rod 508 is engaged with the slots 503 below, limiting the position of the slider 507, so that the three groups of support rods 505 can be fixed, and then the position of the bottom plate 506 can be adjusted to make the bottom plate 506 contact the ground, and the bottom plate 506 is fixed to the ground by bolts to complete the fixation. Through the setting of the support mechanism 5, when fixed on the channel slope, since the channel slope is generally in an inclined state, the three groups of unfolded support rods 505 can make the support mechanism 5 more stable, thereby ensuring the stability of the crack meter 3 during the monitoring process.

[0051] Then the operator can install the connecting plate 1 above the supporting mechanism 5, first make the connecting block 401 correspond to the opening position below the connecting plate 1, and insert the connecting block 401 into the opening below the connecting plate 1. At this time, the arc surface of the wedge block 406 is squeezed by the outer wall below the connecting plate 1, and moves to the inner wall of the connecting block 401, driving the L-shaped rod 405 to move synchronously. The L-shaped rod 405 squeezes the inner wall of the inclined groove 404, so that the turntable 403 moves, and the spiral spring 402 is forced to shrink; when the connecting block 401 moves to the position where the wedge block 406 corresponds to the limit groove 6, the spiral spring 402 drives the turntable 403 to rotate in the opposite direction due to its own elastic force, and the inclined groove 404 drives the L-shaped rod 405 to move, so that the two groups of wedge blocks 406 move synchronously to both sides, and the connecting block 401 is fixed in the inner wall below the connecting plate 1, and the assembly can be completed.

[0052] After the assembly is completed, the operator can align the fixed block 202 above the crack meter 3 with the opening position below the mounting block 201, and insert the fixed block 202 into the mounting block 201. The stopper 208 in the fixed block 202 is squeezed by the inner wall of the mounting block 201, so that the stopper 208 moves to the inner wall of the fixed block 202, and the telescopic spring 207 is forced to shrink; when the fixed block 202 moves to the position where the stopper 208 corresponds to the internal groove of the mounting block 201, the elastic force of the telescopic spring 207 causes the stopper 208 to pop out and engage with the groove, and the fixed block 202 is fixed in the mounting block 201, and the installation of the crack meter 3 is completed, so that the channel slope cracks can be monitored through the crack meter 3. When the crack width changes, the supporting mechanism 5 and the connecting plate 1 on both sides move, and the sensor in the crack meter 3 can monitor the position change and transmit a signal to the operator.

[0053] When it is necessary to disassemble the crack meter 3 and carry the device as a whole for transportation, the concave plate 206 can be pressed to force the return spring 209 to shrink, and the inner wall of the through groove 203 in the concave plate 206 squeezes the sliding rod 204, so that the sliding rod 204 moves along the inner wall of the through groove 203, driving the baffle 205 to move horizontally downward, squeezing the arc surface of the stopper 208, so that the stopper 208 moves inward along the inner wall of the fixed block 202 and breaks away from the contact with the groove on the inner wall of the installation block 201, releasing the limit of the fixed block 202, and taking out the fixed block 202 to complete the disassembly of the crack meter 3; then, by toggling the convex block on the outer wall of the rotating disk 403, the rotating disk 403 and the rotating shaft 407 can be driven to rotate, the volute spring 402 is stretched, and the rotating disk 403 rotates obliquely. The inner wall of the groove 404 squeezes the L-shaped rod 405, so that the L-shaped rod 405 drives the two groups of wedge blocks 406 to move toward the middle at the same time, disengaging from the limit groove 6, releasing the limit of the connecting block 401, removing the connecting plate 1 from the top of the connecting mechanism 4, and then screwing the bolts on the bottom plate 506 to separate the support mechanism 5 from the ground, and pull the pull rod 508 outward, move the slider 507 upward, and drive the three groups of support rods 505 to be folded up through the hinged rod 504, and engage with the upper card slot 503 through the pull rod 508 to fix the support rod 505, which can reduce the volume. In addition, the split design will not take up too much area during carrying and transportation, saving more space, and is also more convenient when transporting to a suitable place for assembly, thereby improving work efficiency.
