Description

Technical Field

[0001] This invention relates to the field of pore pressure sensor embedding technology, specifically to an embedding device for pore pressure sensors. Background Technology

[0002] In the field of geotechnical engineering, whether it is on-site construction or scientific research, in-situ testing is often required to obtain necessary evaluation indicators. Pore water pressure is an important observation indicator in geotechnical engineering. Pore water pressure gauges are often installed on-site to judge the soil reinforcement effect, study the soil strength change law, and analyze the soil consolidation state based on the observation results.

[0003] Publication No. CN217438870U discloses a pore water pressure sensor installation device. A ring clamp is inserted from the bottom of the pore water pressure sensor, with the ring top of the clamp positioned below the limiting clamp. The pore water pressure sensor with the clamp installed is placed at the installation location. The clamp is checked to see if it can lock itself in the hole. If not, the opening angle of the clamp's jaws needs to be manually adjusted until it locks in. A top connecting sleeve is then placed on top of the pore water pressure sensor and connected to the bottom of the drill rod. The drill rod is lowered, and once the pore water pressure sensor reaches the target location, the lowering is stopped. The pore water pressure sensor is then connected to a data acquisition device to check if it functions normally. If it does, the next step is performed. If the pore water pressure sensor does not function normally, it has been damaged during lowering and needs to be removed and a new sensor installed. However, this patent has the following problems in practical use:

[0004] While this pore water pressure sensor installation device can achieve the installation of pore water pressure sensors, it requires drilling before installation. The device cannot drill holes of corresponding depths based on the burial height, hindering the installation of the sensor at the designated depth for water pressure detection. Furthermore, the installation process requires manual adjustment to unfold the clamping ring, which is cumbersome and unsuitable for deeper holes. Once the clamping ring is inserted into the soil, it is difficult to retract, preventing the sensor from being reused. Existing technologies use drills to create holes of appropriate depths for sensor installation, but this process cannot promptly remove debris and soil from the holes, affecting drilling efficiency. Additionally, cleaning the hole and surrounding area after drilling is inconvenient, further impacting the sensor's installation effectiveness.

[0005] Therefore, an embedded device for pore pressure sensors is proposed to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to provide an embedding device for a pore pressure sensor, to solve the problems mentioned in the background art, such as the need for drilling before installing the pore water pressure sensor, the inability to drill holes of appropriate depth according to the embedment height, the difficulty in installing the pore water pressure sensor at a specified depth for water pressure detection, the need for manual adjustment to unfold the clamping ring during installation, which is not only cumbersome but also unsuitable for deeper holes. Once the clamping ring is inserted into the soil, it is difficult to retract it, preventing the reuse of the pore water pressure sensor. Furthermore, it is difficult to clean debris and soil from the hole in a timely manner during drilling, affecting the drilling effect. Additionally, it is inconvenient to clean the hole and surrounding area after drilling, thus affecting the installation effect of the pore water pressure sensor.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows: This pore pressure sensor embedding device uses a drilling conveyor cylinder to drive the first mounting ring and drilling teeth to rotate, performing initial drilling through the drilling teeth. Utilizing the characteristics of the clamping sliding rod and clamping protrusion engaging with the fixing groove, the first mounting seat drives the drilling bit to rotate, performing secondary drilling. The conveying motor drives the conveying rotating rod and conveying spiral blade to rotate, and the structural characteristics of the conveying spiral blade transport the soil and stones generated during drilling to a collection box. The drilling conveyor cylinder drives the cleaning scraper to rotate, collecting the transported soil and stones, which are then discharged through a drain valve. By changing the rotation angle of the spiral cleaning blade, the spiral cleaning blade is extended, cleaning not only the inside of the borehole but also the surface, preventing soil and stones from falling into the hole and affecting the installation and detection effect of the pore water pressure sensor. The specific details are as follows:

[0023] 1. By setting up a drilling and cleaning mechanism, not only can the first rotating motor drive the first rotating worm to rotate, but the meshing connection between the first rotating worm and the first rotating worm wheel can also drive the drilling conveyor cylinder to rotate. The drilling conveyor cylinder can then drive the first mounting ring and the drilling teeth to rotate, performing preliminary drilling through the drilling teeth. Simultaneously, the clamping motor can be started to drive the first bevel gear to rotate. The meshing connection between the first bevel gear and the second bevel gear can then drive the clamping threaded rod to rotate. At the same time, the clamping threaded sleeve can drive the clamping sliding rod and the clamping protrusion to unfold and move. The clamping sliding rod and the clamping protrusion can then engage with the fixed groove, causing the first mounting seat to drive the drilling bit to rotate. The drilling bit can then perform secondary drilling, thereby improving drilling efficiency. By starting the conveying motor, the conveying rotating rod and the conveying spiral blade can be driven to rotate. The structural characteristics of the conveying spiral blade can then be used to transport the soil and stones generated during drilling to the collection box. The drilling conveyor cylinder can drive the cleaning scraper to rotate, collecting the conveyed soil and stones and discharging them through the drain valve.

[0024] 2. By setting up a cleaning and installation mechanism, not only can the entire device be moved using a burial mobile vehicle, but the second rotating motor is also started to drive the second rotating worm gear to rotate. Utilizing the meshing connection between the second rotating worm gear and the second rotating worm wheel, the second rotating worm wheel drives the rotating connecting block and connecting bracket to rotate. After drilling the hole with the drilling bit, the drilling bit is moved to the top of the burial mobile vehicle. The second rotating motor then moves the drill bit placement frame to the top of the drilling bit. The clamping motor drives the clamping sliding rod and clamping protrusion to retract. When the clamping sliding rod and clamping protrusion separate from the first mounting seat, the drilling bit... The cleaning rack falls into the drill bit holder. The second rotating motor moves the cleaning rack to the bottom of the clamping bracket. The clamping motor then activates, causing the clamping sliding rod and clamping protrusion to unfold. When the clamping sliding rod and clamping protrusion engage with the mounting slot inside the second mounting base, the clamping bracket is connected to the second mounting base. Simultaneously, the unfolding motor activates, driving the unfolding main gear to rotate. Utilizing the meshing connection between the unfolding main gear and the meshing gear, the meshing gear drives the meshing gear ring to rotate. Utilizing the meshing connection between the meshing gear ring and the driven gear, the driven gear drives the rotating block and the spiral cleaning blade to rotate. By changing the spiral... The rotation angle of the spiral cleaning blades allows for their extension, cleaning not only the interior of the borehole but also its surface. This prevents dirt and stones from falling into the hole and affecting the installation and detection performance of the pore water pressure sensor. After cleaning, the second mounting base is placed on the cleaning rack. Utilizing the magnetic connection between the fixed magnet and the iron block inside the fixing groove, the top of the telescopic rod can be installed. The second mounting ring is then installed at the bottom of the clamping bracket, extending to the corresponding depth in the borehole. Activating the clamping motor causes the clamping sliding rod to move the clamping protrusion. The device unfolds, and the fixed magnet drives the sliding limit block and the installation telescopic rod to slide relative to each other inside the second mounting ring in the fixed groove. The fixing pins can be used to fix the entire second mounting ring, improving the installation stability of the pore water pressure sensor and avoiding errors in the detection data caused by unstable installation. By starting the upgrade motor, the lifting rotating rod and the bevel gear transmission assembly are rotated, which in turn drives the lifting threaded rod to rotate. At the same time, the lifting threaded sleeve drives the fixed ring to move up and down. This not only enables control of the drilling depth but also facilitates the accurate installation of the pore water pressure sensor. Attached Figure Description

[0043] Working principle: Before using this type of pore pressure sensor installation device, it is necessary to check the overall condition of the device to ensure that it can work normally.

Secondary drilling is performed through the drilling bit 128, thereby improving drilling efficiency. By starting the conveying motor 111, the conveying rotating rod 112 and the conveying spiral blade 113 are driven to rotate. Utilizing the structural characteristics of the conveying spiral blade 113, the soil and stones generated during drilling are conveyed to the collection box 106. The drilling conveying cylinder 108 drives the cleaning scraper 110 to rotate, which can collect the conveyed soil and stones and discharge them through the drain valve 107.

[0044] Secondly, the entire device is moved using the installation vehicle 201. Simultaneously, the second rotary motor 204 is started, driving the second rotary worm 205 to rotate. Utilizing the meshing connection between the second rotary worm 205 and the second rotary worm wheel 206, the second rotary worm wheel 206 drives the rotating connecting block 207 and the connecting bracket 208 to rotate. After drilling with the drill bit 128, the drill bit 128 is moved to the top of the installation vehicle 201. The second rotary motor 204 moves the drill bit placement rack 217 to the top of the drill bit 128. The clamping motor 119 drives the clamping sliding rod 124 and the clamping protrusion 125 to retract. When the clamping sliding rod 124 and the clamping protrusion 125 separate from the first mounting base 127, the drill bit 128 falls into the drill bit placement rack 217. The second rotary motor 204 moves the cleaning placement rack 218 to the bottom of the clamping bracket 118. The clamping motor 119 is then started, driving the clamping... The sliding rod 124 and clamping protrusion 125 are unfolded. When the sliding rod 124 and clamping protrusion 125 engage with the mounting slot 220 inside the second mounting base 219, the clamping bracket 118 is connected to the second mounting base 219. Simultaneously, the unfolding motor 222 is started, driving the unfolding main gear 223 to rotate. Utilizing the meshing connection between the unfolding main gear 223 and the meshing gear 224, the meshing gear 224 drives the meshing gear ring 225 to rotate. Utilizing the meshing connection between the meshing gear ring 225 and the driven gear 226, the driven gear 226 drives the rotating block 227 and the spiral cleaning blade 228 to rotate. By changing the rotation angle of the spiral cleaning blade 228, the spiral cleaning blade 228 is extended. This not only cleans the inside of the borehole but also the surface of the borehole, preventing mud and stones from falling into the borehole and affecting the installation and detection effect of the pore water pressure sensor 210.

[0045] Finally, after the hole is cleaned, the second mounting base 219 is placed on the cleaning placement rack 218. Simultaneously, utilizing the magnetic connection between the fixing magnet 215 and the iron block inside the fixing groove 126, the top of the telescopic rod 213 can be installed. The second mounting ring 211 is installed at the bottom of the clamping bracket 118 and extends to the corresponding depth of the hole. By activating the clamping motor 119, the clamping sliding rod 124 drives the clamping protrusion 125 to unfold. In the fixing groove 126, the fixing magnet 215 drives the sliding limit block 214 and the telescopic rod 213 to slide relative to each other inside the second mounting ring 211. The fixing pins 216 can be used to fix the entire second mounting ring 211, improving the installation stability of the pore water pressure sensor 210 and avoiding errors in the detection data due to unstable installation. By starting the upgrade motor 230, the lifting rotating rod 231 and the bevel gear transmission assembly 232 are driven to rotate, which in turn drives the lifting threaded rod 233 to rotate. At the same time, the lifting threaded sleeve 234 drives the fixing ring 101 to move up and down. This not only enables control of the drilling depth but also facilitates the accurate installation of the pore water pressure sensor 210.
