Description

Technical Field

[0001] This application relates to the field of geological engineering measurement technology, specifically a device for measuring hydraulic ring geological fractures. Background Technology

[0002] Hydrogeology and environmental geology is a collective term encompassing hydrogeology, engineering geology, and environmental geology. It primarily involves investigating and evaluating the geological conditions of groundwater resources, engineering construction, and the natural environment. Ground fissures are progressive hazards that develop gradually. Based on their causes, they can be divided into two main categories: one is tectonic ground fissures formed by internal forces, such as earthquake fissures, active ground fissures due to basement faults, and fissures that open from hidden fissures; the other is non-tectonic ground fissures, which are ground fissures formed by external forces, such as ground fissures caused by erosion in loose soil, ground fissures in loess collapsing soil, ground fissures caused by expansion and contraction in expansive soil, and ground fissures caused by landslides. Tectonic ground fissures extend stably and are not affected by surface topography, soil and rock properties, or other geological conditions. Therefore, hydrogeological and environmental geology fissure measuring devices are needed for their measurement.

[0003] An existing patent (publication number: CN219589598U) discloses a hydraulic ring geological fracture measuring device, comprising: a horizontal box, with scale lines on both sides of the front of the horizontal box; a transmission frame slidably mounted on both sides of the outer wall of the horizontal box, a stop pin fixedly mounted at the bottom of the transmission frame, and infrared ranging sensors embedded on the opposite sides of the two stop pins. In this hydraulic ring geological fracture measuring device, the infrared ranging sensors are activated periodically. When a crack is detected to be expanding, a drive motor rotates a threaded rod, causing the stop pins to re-engage with the crack. If a touch block contacts a touch switch at this time, an alarm is activated, thus achieving automatic alarm and warning when the crack expands to a certain range. This eliminates the need for manual monitoring of the crack in real time, improving monitoring safety. Furthermore, the distance between the sliding frame and the transmission frame is adjustable, allowing for flexible adjustment of the crack alarm range.

[0004] However, it was found in the above solution that when using a measuring device to measure cracks, impurities are usually present in the cracks, and the above solution cannot remove the impurities in the cracks. During measurement, the presence of impurities will affect the measurement accuracy, resulting in a decrease in measurement accuracy and the inability to obtain accurate measurement data. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a hydrogeological crack measuring device that can blow away impurities at the crack location, preventing impurities in the crack from affecting measurement accuracy. This solves the problem that existing technologies cannot remove impurities from cracks, and the presence of impurities during measurement affects measurement accuracy, leading to a decrease in measurement accuracy and the inability to obtain accurate measurement data.

[0006] To achieve the above objectives, this application provides the following technical solution: a hydrogeological crack measuring device, comprising an installation strip, an air pump fixedly installed on the upper surface of the installation strip, an air inlet pipe fixedly installed at the input end of the air pump, a hose I fixedly installed at the output end of the air pump, a hose II fixedly connected to the outer surface of the hose I, a sliding groove formed on the bottom surface of the installation strip, a fixing block fixedly connected to the inner wall of the sliding groove, a sliding block slidably connected to the inner wall of the sliding groove, mounting components fixedly connected to the bottom surfaces of the fixing block and the sliding block, a stop pin fixedly connected to the bottom surface of each mounting component, air holes arranged at equal intervals formed on the mutually distant sides of each stop pin, the other ends of hose I and hose II fixedly connected to the interior of the corresponding stop pin, a limiting block fixedly connected to the upper surface of the installation strip, and the inner wall of the limiting block fixedly connected to the outer surface of hose I.

[0007] To prevent impurities from affecting measurement accuracy in the cracks being measured, an air pump is installed on the upper surface of the mounting strip. The air inlet pipe is connected to the air pump's inlet, and gas is transmitted through the air pump, hose one, and hose two. A sliding groove is created on the bottom surface of the mounting strip, and a fixing block and a sliding block are placed on the inner wall of the sliding groove. The mounting component is connected to the fixing block and the sliding block. The hollow stop pins are connected to their corresponding stop pins, and air holes are created on the opposite sides of the stop pins. Hose one and hose two are connected to their corresponding stop pins, allowing the gas transmitted into the stop pins through the air holes to be discharged. This allows the discharged gas to act on the crack location, blowing away impurities and preventing impurities from affecting measurement accuracy.

[0008] Furthermore, mounting blocks are fixedly connected to both the left and right ends of the mounting strip, and a motor is fixedly connected inside one of the mounting blocks.

[0009] The above method involves installing mounting blocks on the left and right ends of the mounting strip for a fixed connection, and installing a motor inside the mounting block on the left side to achieve the desired positioning and installation effect for the motor.

[0010] Furthermore, the output shaft of the motor is fixedly connected to a threaded rod, and the other end of the threaded rod is rotatably connected to the inner wall of the corresponding mounting block.

[0011] The above scheme involves mounting the threaded rod on the output shaft of the motor as a fixed connection, allowing the threaded rod to rotate via the motor, and connecting the other end of the threaded rod to the mounting block on the right side as a rotatable connection. The mounting block can limit the movement of the right end of the threaded rod.

[0012] Furthermore, a pointer is fixedly mounted on the front of one of the stop pins.

[0013] The above method involves mounting the pointer on the front of the right movable stop pin and fixing it with bolts. The pointer can be moved by moving the right movable stop pin, making it easier to observe the position the pointer is pointing to and to observe the test data.

[0014] Furthermore, the outer surface of the threaded rod is rotatably connected to the inner wall of the fixed block, and the outer surface of the threaded rod is threadedly connected to the inner wall of the sliding block.

[0015] The above scheme connects the threaded rod to the inner wall of the fixed block in a rotating connection. The fixed block can limit and support the left end of the threaded rod. The threaded rod is connected to the sliding block in a threaded connection. The rotation of the threaded rod allows the sliding block to move, which in turn allows the sliding block to move the stop pin below, facilitating the measurement of cracks.

[0016] Furthermore, a scale is fixedly connected to the front of the mounting strip, and the side of each mounting block that is close to each other is fixedly connected to the end of the scale.

[0017] The above method involves installing the scale on the front of the mounting strip and fixing it between them. The pointer points to the surface of the scale, and the movement of the stop pin makes the pointer point to the corresponding position on the scale. This allows for easy observation of the pointer's position after the stop pin moves. The mounting block is then connected to the scale to achieve the installation of both ends of the scale.

[0018] Furthermore, two base plates are provided below the scale, and two universal wheels are fixedly installed on the bottom surface of each base plate, and a support block is fixedly connected to the upper surface of each base plate.

[0019] The above scheme involves placing the base plate below the scale and installing the casters on the bottom surface of the base plate for a fixed connection. The casters facilitate the movement of the entire device. The support blocks are then installed on the upper surface of the corresponding base plate to achieve the installation of the support blocks.

[0020] Furthermore, a telescopic rod is fixedly installed on the upper surface of each support block, and the output end of each telescopic rod is fixedly connected to the bottom surface of the corresponding mounting block.

[0021] The above method involves installing the telescopic rod on the upper surface of the support block as a fixed connection, and connecting the output end of the telescopic rod to the corresponding mounting block. The telescopic rod allows the mounting block to rise and fall, which in turn allows the stop pin to rise and fall, making it easier to insert the stop pin into the crack for detection.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This hydrogeological fracture measuring device comprises an air pump, a first hose, a second hose, and a stop pin. When measuring the fracture, the air pump is activated to draw air through the air inlet pipe. The air is then transmitted through the first and second hoses to the corresponding stop pin. The air is expelled through vents on the stop pin's surface, allowing it to act on the fracture location and blow away impurities, preventing them from affecting measurement accuracy. During measurement, the stop pin is lowered to a designated height using a telescopic rod. The fixed stop pin on the left side is then aligned with one side of the fracture. The motor is then activated, causing the threaded rod to rotate. This rotation, via the threaded rod, moves the movable stop pin, which then contacts the other side of the fracture. At this point, the pointer indicates the scale position, facilitating data observation. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] Please see Figure 3 , Figure 4 and Figure 5 This embodiment of a hydrogeological crack measuring device includes an installation strip 1.

The other ends of the hose 4 and the hose 5 are fixedly connected to the interior of the corresponding stop pin 10. A limiting block 12 is fixedly connected to the upper surface of the installation strip 1. The inner wall of the limiting block 12 is fixedly connected to the outer surface of the hose 4.

[0033] Please see Figure 1 , Figure 2 and Figure 5 Mounting blocks 13 are fixedly connected to the left and right ends of mounting strip 1. A motor 14 is fixedly connected inside one of the mounting blocks 13. Mounting blocks 13 are installed on the left and right ends of mounting strip 1 to form a fixed connection. The motor 14 is installed inside the mounting block 13 on the left side to achieve the positioning and installation effect of the motor 14.

[0034] Please see Figure 5 The output shaft of the motor 14 is fixedly connected to a threaded rod 15. The other end of the threaded rod 15 is rotatably connected to the inner wall of the corresponding mounting block 13. The threaded rod 15 is mounted on the output shaft of the motor 14 and is set as a fixed connection. The motor 14 enables the threaded rod 15 to rotate. The other end of the threaded rod 15 is connected to the mounting block 13 on the right side and is set as a rotatable connection. The mounting block 13 can limit the right end of the threaded rod 15.

[0035] Please see Figure 4 One of the stop pins 10 has a pointer 16 fixedly mounted on its front side. The pointer 16 is mounted on the front side of the right movable stop pin 10 and fixed with bolts. The pointer 16 can be moved by moving the right movable stop pin 10, making it easy to observe the position pointed to by the pointer 16 and to facilitate the observation of detection data.

[0036] Please see Figure 5The outer surface of the threaded rod 15 is rotatably connected to the inner wall of the fixed block 7, and the outer surface of the threaded rod 15 is threadedly connected to the inner wall of the sliding block 8. The threaded rod 15 is connected to the inner wall of the fixed block 7 in a rotatable connection. The fixed block 7 can limit and support the left end of the threaded rod 15. The threaded rod 15 is connected to the sliding block 8 in a threaded connection. The rotation of the threaded rod 15 allows the sliding block 8 to move, which in turn allows the sliding block 8 to drive the lower stop needle 10 to move, facilitating the measurement of cracks.

[0037] Please see Figure 1 , Figure 2 and Figure 3 A scale 17 is fixedly connected to the front of the mounting strip 1. The side of each mounting block 13 that is close to each other is fixedly connected to the end of the scale 17. The scale 17 is installed on the front of the mounting strip 1 and fixed between them. The pointer 16 points to the surface of the scale 17. The pointer 16 points to the corresponding position of the scale 17 by the movement of the stop pin 10. Thus, after the stop pin 10 moves, it is easy to observe the position of the pointer 16. The mounting block 13 is connected to the scale 17 to realize the installation of both ends of the scale 17.

[0038] Please see Figure 1 , Figure 2 and Figure 3 Below the scale 17 are two base plates 18. Two casters 19 are fixedly installed on the bottom surface of each base plate 18. A support block 20 is fixedly connected to the upper surface of each base plate 18. The base plates 18 are set below the scale 17, and the casters 19 are installed on the bottom surface of the base plates 18 for fixed connection. The casters 19 facilitate the movement of the whole device. The support blocks 20 are installed on the upper surface of the corresponding base plates 18 to realize the installation of the support blocks 20.

[0039] Please see Figure 1 , Figure 2 and Figure 3 Each support block 20 has a telescopic rod 21 fixedly installed on its upper surface. The output end of each telescopic rod 21 is fixedly connected to the bottom surface of the corresponding mounting block 13. The telescopic rod 21 is installed on the upper surface of the support block 20 and fixedly connected. The output end of the telescopic rod 21 is connected to the corresponding mounting block 13. The mounting block 13 can be raised and lowered by the telescopic rod 21, which in turn allows the stop needle 10 to be raised and lowered, making it easier to insert the stop needle 10 into the crack for detection.

[0040] This embodiment of a hydraulic ring geological fracture measuring device includes components such as an air pump 2, a first hose 4, a second hose 5, and a stop pin 10. When measuring the fracture, the air pump 2 is activated to draw air through the air inlet pipe 3. The air output from the air pump 2 is transmitted to the corresponding stop pin 10 through the first hose 4 and the second hose 5. The air is discharged through the air hole 11 on the surface of the stop pin 10, allowing the discharged air to act on the fracture location and blow away impurities in the fracture location, preventing impurities in the fracture from affecting the measurement accuracy. During measurement, the stop pin 10 is lowered to a specified height by the telescopic rod 21. Then, the fixed stop pin 10 on the left side is aligned with one side of the fracture. Subsequently, the motor 14 is activated to rotate the threaded rod 15. The threaded rod 15 causes the sliding block 8 to move the movable stop pin 10 until the movable stop pin 10 contacts the other side of the fracture. At this time, the pointer 16 points to the scale position of the ruler 17, which is convenient for observing the measurement data.

[0041] It should be noted that the telescopic rod 21 is electrically telescopic, which has the advantages of fast response speed and stability. The caster wheel 19 has a locking mechanism, which can improve the stability of the device.

[0042] The working principle of the above embodiments is as follows:

[0043] First, the device is moved to the crack location to be measured using the casters 19 and the base plate 18. Then, the telescopic rod 21 is activated to lower the mounting block 13, which in turn lowers the stop pin 10, bringing the fixed stop pin 10 on the left side into contact with one side of the crack. The casters 19 are then locked, and the air pump 2 is activated to draw air through the air inlet pipe 3. The air output from the air pump 2 is transmitted to the corresponding stop pin 10 through the hoses 4 and 5. The air is then discharged through the air holes 11 on the surface of the stop pin 10, allowing it to act on the crack location and blow away impurities, preventing impurities from affecting the measurement accuracy. While blowing air, the motor 14 drives the threaded rod 15 to rotate, causing the sliding block 8 to move. This causes the sliding block 8 to move the movable stop pin 10 on the right side until the stop pin 10 contacts the other side of the crack. At this point, the pointer 16 points to the scale 17, making it easy for the staff to observe and record the measurement data.
