Description

Technical Field

[0001] The utility model relates to the technical field of crack detection equipment, and specifically relates to a dam crack detection device. Background Art

[0002] To ensure the working safety of the dam, it is often necessary to monitor the cracks that appear on the dam, and thus crack detection equipment is required. The utility model patent with the patent application number CN201820384820.9 discloses a crack detection device. The projection module projects a grid-like image onto the concrete surface to divide and position the photographed concrete surface. When the light is insufficient, the supplementary light module is used for supplementary lighting. The photography module sends the photographed information to the controller and stores it in the storage module, and sends it to the mobile client in real time through the wireless communication module for real-time monitoring and convenient real-time positioning. The telescoping of the first cylinder can adjust the length of the vertical arm, the telescoping of the second cylinder can adjust the length of the lower cross arm, and the telescoping of the third cylinder can adjust the length of the upper cross arm. The setting of the locking screw can rotate the angle of the lower cross arm, thereby realizing the angle adjustment of the crack detection device. According to the disclosed technical solution, when the existing crack detection equipment is in use, on the one hand, it is often unable to effectively ensure that the distance between the detection probe and the crack is consistent, and thus it is easy to cause inaccurate crack detection due to the distance change. On the other hand, during the detection work, it is easy for the detection probe to be attached with dust or soiled by the floating dust on the dam, resulting in an unclear photographed image, which is not conducive to ensuring the smooth progress of the detection work.

[0003] Therefore, how to design a dam crack detection device has become a problem to be solved currently. Content of the Utility Model

[0004] The present model aims to solve the problem of the consistent distance between the detection probe and the crack, solve the problem of inaccurate crack detection caused by the distance change, and solve the problem of unclear photographed images caused by the detection probe being attached with dust or soiled by the floating dust on the dam.

[0005] To solve the above problems, the present application is realized through the following technical solutions:

[0006] A dam crack detection device includes a crack detector. A display screen and a switch group are installed on the crack detector. The bottom of the crack detector is welded with a handle. The probe is clamped on the inner wall of the bottom of the handle. The handle is also provided with an inlet and an outlet. A latch is connected through the upper side wall of the handle. A spring is sleeved outside the latch, and the inner side of the latch is in fit with the bayonet on the side wall of the probe.

[0007] The display screen is fixedly connected to the inside of the crack detector by bolts.

[0008] The crack detector is connected to the probe through a cable, and a micro scale is bonded to the top of the probe.

[0009] Multiple rollers are fixedly connected to the top of the probe through bolts.

[0010] A motor is installed inside the handle. The motor is fixedly connected to the inner wall of the top of the handle, and the output shaft of the motor is connected to the top of multiple fan blades.

[0011] The bottom of the sponge is clamped to the top of the probe, and the top of the sponge is installed at the bottom of the fan blade through bolts.

[0012] One side of the spring is connected to the retaining pin, and the other side of the spring is connected to the outside of the handle.

[0013] The switch group is connected to the motor, the crack detector, and the display screen through wires.

[0014] The inlet is located outside the sponge.

[0015] The outlet is located above the fan blade.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] 1. When the dam crack detection device is in use, the rollers on the probe are clamped on the surface of the dam, and the probe is moved along the direction of the crack through the rollers. After the crack is photographed by the probe, it is transmitted to the crack detector. After the crack detector calculates the width of the crack, it is displayed in real time through the display screen. At the same time, when the probe photographs the crack, the picture of the micro scale is also photographed. Personnel can use the micro scale to verify the width of the crack calculated by the crack detector in real time. The rollers are used to keep the distance between the probe and the crack constant, thereby avoiding errors in the calculation of the crack width caused by changes in the distance between the probe and the crack, and ensuring the accuracy of the dam crack detection work.

[0018] 2. When the dam crack detection device is in use, when dust adheres to the probe or the micro scale, and floating soil on the dam adheres to the probe or the micro scale during the detection work, the probe is inserted into the inside of the handle. The spring pulls the retaining pin to fix the probe, and the motor is turned on. The motor drives the sponge to clean the probe or the micro scale. At the same time, the motor drives the fan blade to rotate, sucking air through the inlet into the inside of the handle and then flowing out through the outlet. The airflow takes away the dust generated during the cleaning work, thereby effectively cleaning the probe and the micro scale, avoiding unclear shooting pictures of the crack caused by the probe or the micro scale being soiled, and ensuring the smooth progress of the dam crack detection work.

[0019] 3. The dam crack detection device is reasonably designed, efficient and convenient to use, and is suitable for the detection work of dam cracks.

The roller 14 is installed on the top of the probe 4 through bolts. The rollers 14 are symmetrically distributed on the top of the probe 4. During use, the rollers 14 on the probe 4 are stuck on the surface of the dam, and the probe 4 is moved along the direction of the crack through the rollers 14. After the crack is photographed by the probe 4, it is transmitted to the crack detector 1. After the crack detector 1 calculates the width of the crack, it is displayed in real time through the display screen 3. At the same time, when the probe 4 photographs the crack, the image of the micrometer scale 15 is also photographed. Personnel can use the micrometer scale 15 to verify the width of the crack calculated by the crack detector in real time. The rollers 14 are used to keep the distance between the probe 4 and the crack constant, thereby avoiding errors in the calculation of the crack width caused by changes in the distance between the probe 4 and the crack, and ensuring the accuracy of the dam crack detection work. The fan blade 10 does not contact the inner wall of the handle 2.

[0033] In this embodiment, the handle 2 is welded to the bottom of the crack detector 1, the display screen 3 is installed inside the crack detector 1 by bolts, the probe 4 is stuck on the inner wall of the bottom of the handle 2, a bayonet is provided on one side of the probe 4, one end of the latch 7 is connected to the outer side of the handle 2 through a spring 8, the other end of the latch 7 passes through the handle 2 and extends to the inside of the bayonet, the motor 9 is installed on the inner wall of the top of the handle 2 by bolts, a fan blade 10 is installed inside the handle 2, the top of the fan blade 10 is key-connected to the output shaft of the motor 9, the bottom of the sponge 11 is stuck on the top of the probe 4, and the top of the sponge 11 is installed on the bottom of the fan blade 10 by bolts. The inlet 12 and the outlet 13 are both provided on the handle 2. The inlet 12 is located outside the sponge 11, and the outlet 13 is located on the top of the fan blade 10. When in use, when dust adheres to the probe 4 or the micro scale 15, and floating soil on the dam adheres to the probe 4 or the micro scale 15 during the detection work, the probe 4 is inserted into the inside of the handle 2. The spring 8 pulls the latch 7 to fix the probe 4, and the motor 9 is turned on. The motor 9 drives the sponge 11 to clean the probe 4 or the micro scale. At the same time, the motor 9 drives the fan blade 10 to rotate, sucks air into the inside of the handle 2 through the inlet 12, and then flows out through the outlet 13. The airflow takes the dust generated by the cleaning work outwards, thereby effectively cleaning the probe 4 and the micro scale 15, avoiding unclear shooting images of cracks caused by the dirt on the probe 4 or the micro scale 15, and thus ensuring the smooth progress of the dam crack detection work.

[0034] The crack detection device of the dam provides electrical energy for all electrical equipment through the crack detector 1. When in use, the rollers 14 on the probe 4 are stuck on the surface of the dam, and the probe 4 is moved along the direction of the crack through the rollers 14. After the crack is photographed by the probe 4, it is transmitted to the crack detector 1. After the crack detector 1 calculates the width of the crack, it is displayed in real time through the display screen 3. At the same time, when the probe 4 photographs the crack, the picture of the micro scale 15 is also photographed. Personnel can use the micro scale 15 to verify the width of the crack calculated by the crack detector in real time. The rollers 14 are used to keep the distance between the probe 4 and the crack constant, thereby avoiding errors in the calculation of the crack width due to changes in the distance between the probe 4 and the crack, and ensuring the accuracy of the dam crack detection work. When in use, when dust adheres to the probe 4 or the micro scale 15, or floating soil on the dam adheres to the probe 4 or the micro scale 15 during the detection work, the probe 4 is inserted into the inner side of the handle 2. The spring 8 pulls the latch 7 to fix the probe, and the motor 9 is turned on. The motor 9 drives the sponge 11 to clean the probe or the micro scale. At the same time, the motor 9 drives the fan blade 10 to rotate, sucking air into the inner side of the handle 2 through the inlet 12 and flowing out through the outlet 13. The airflow takes the dust generated by the cleaning work outwards, thereby effectively cleaning the probe 4 and the micro scale 15, and avoiding unclear crack photography pictures due to the probe 4 or the micro scale 15 being soiled, and thus ensuring the smooth progress of the dam crack detection work.

[0035] When the device is working, multiple rollers 14 need to be placed on both sides of the crack, and the probe 4 is moved along the direction of the crack, so that the rollers 14 need to roll along the direction of the crack on both sides of the crack. At this time, the rollers 14 need to be symmetrically distributed. Thus, the rollers 14 on the probe 4 are stuck on the surface of the dam. When working, the latch 7 is pulled out and the probe 4 is taken out, and then the probe 4 is rotated 180 degrees so that the rollers 14 on the probe rotate to the lower side.

[0036] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementations that can be understood by those skilled in the art.
