Description

Technical Field

[0001] This invention relates to the field of monitoring device technology, specifically a building foundation settlement monitoring device. Background Technology

[0002] Foundation settlement is a typical geological and structural safety hazard in the field of building engineering. Its causes include a variety of factors such as underground resource extraction, construction disturbance, natural soil consolidation, and changes in groundwater level. It can directly cause problems such as building tilting and cracking, underground pipeline damage, and reduced foundation bearing capacity, seriously threatening the structural safety of buildings and the safety of residents' lives and property. Therefore, accurate and continuous monitoring of building foundation settlement has become a core requirement in the construction and operation and maintenance phases of engineering projects, and has also driven the technological iteration and upgrading of monitoring devices.

[0003] However, in the use of existing monitoring devices, the outriggers are mostly single telescopic structures with cumbersome adjustment methods. It is difficult to adjust the height of each support end for different ground conditions such as potholes, soft ground, and slopes. This makes it difficult for each support end to fit evenly with the ground and to form a stable erection benchmark. Summary of the Invention

[0004] The purpose of this invention is to provide a building foundation settlement monitoring device. By setting up an adjustment part, it solves the problems of existing monitoring devices, where the outriggers are mostly single telescopic structures with cumbersome adjustment methods, making it difficult to adjust the height of each support end for different ground conditions such as potholes, soft ground, and tilt, and making it difficult for each support end to fit evenly with the ground and form a stable erection benchmark.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to a building foundation settlement monitoring device, comprising a support rod and a monitoring device fixedly connected to the top of the support rod, and further comprising: an adjustment part mounted on the support rod; a fixing part disposed on the adjustment part; a storage part comprising several storage parts, each mounted on the support rod; a protective part mounted on the support rod; the adjustment part comprising a hinge assembly mounted on the support rod; and an extension assembly disposed on the hinge assembly; the hinge assembly comprising a fixing ring I fixedly connected to the outer wall of the support rod, a fixing ring II fixedly connected to the outer wall of the support rod, and a plurality of hinge blocks I fixedly connected to the outer wall of the fixing ring I, each of the hinge blocks I having a hinge rod hinged to the side away from the support rod, and four hinge blocks I and four hinge rods arranged in a circular array.

[0007] Furthermore, the storage unit includes a hinge block four fixedly connected to the outer wall of the fixing ring two, a hinge block five hingedly disposed on the hinge block four, a hinge block six fixedly connected to the left side of the hinge rod, a hinge block seven hingedly disposed at the bottom of the hinge block six, a limiting member one disposed on the hinge block five, the hinge block five and the hinge block seven being opposite to each other, the limiting member one including a hollow rod fixedly connected to the top of the hinge block five, an extension rod slidably connected to the inner wall of the hollow rod, a threaded rod threadedly connected to the extension rod, a handle two fixedly connected to the right side of the threaded rod, and the threaded rod contacting the extension rod.

[0008] Furthermore, the protective part includes a fixing plate sleeved on the outer wall of the support rod. A connecting ring is fixedly connected to the outer wall of the support rod. Several adapter plates are fixedly connected to the bottom of the fixing plate, and adapter plates are fixedly connected to the top of the connecting rings. The adapter plates are respectively adapted to the adapter plates. A limiting member is provided on the support rod. Four adapter plates and four adapter plates are provided. Both adapter plates are L-shaped. The limiting member includes a sliding ring slidably connected to the outer wall of the support rod. Several connecting rods are fixedly connected to the top of the sliding ring. The connecting rods pass through the corresponding adapter plates. Several springs are sleeved on the outer wall of the connecting rod. The tops of the springs are fixedly connected to the connecting rings, and the bottoms of the springs are fixedly connected to the sliding rings. After installation, the springs are in a stretched state.

[0009] Furthermore, the extension assembly includes a slide rod slidably connected to the inner wall of the hinge rod, a limiting groove is formed on the slide rod, a limiting rod passes through the hinge rod, the limiting rod extends into the limiting groove, a fixing ring is fixedly connected to the front side of the limiting rod, an auxiliary component is provided on the limiting rod, and the limiting groove is adapted to the limiting rod.

[0010] Furthermore, the connecting assembly includes a second hinge block fixedly connected to the bottom of the slide bar, a third hinge block hinged to the bottom of the second hinge block, a first connecting rod rotatably connected to the bottom of the third hinge block, and a connecting plate fixedly connected to the bottom of the first connecting rod.

[0011] Furthermore, the limiting component includes several connecting rods 2 rotatably connected to the bottom of the connecting plate, each connecting rod 2 having a limiting rod 2 fixedly connected to its outer wall, each connecting rod 2 having a worm spring fixedly connected to its outer wall, each worm spring having a fixing block fixedly connected to its end, each connecting rod 2 having a connecting plate at its bottom, and each connecting rod 2 being rotatably connected to the connecting plate. There are five connecting rods 2, five limiting rods 2, five worm springs, and five fixing blocks, arranged in a circumferential array.

[0012] The present invention has the following beneficial effects: 1. This invention, by setting an adjustment part, allows the operator to adjust the length of the sliding rod after the entire device is fully extended, according to the site conditions. First, manually pull handle one. Under the pulling force, the limiting rod one linked with handle one will gradually disengage from the preset limiting groove of the sliding rod. At the same time, the fixing ring that moves synchronously with handle one will stretch the spring. After the limiting rod one is completely freed from the constraint of the limiting groove, the sliding rod is released from the limiting state. The operator can pull the sliding rod as needed to adjust its overall extension length to adapt to the unevenness of the ground. After the length is adjusted to the correct position, the operator releases handle one. The stretched spring will drive the fixing ring and limiting rod one to automatically reset. The limiting rod one will re-embed into the corresponding limiting groove, completing the locking of the sliding rod length. This enables the support mechanism to adapt to complex ground conditions, adjusting the support height for various working conditions such as potholes, soft ground, and sloping ground. This ensures that each support end of the support mechanism can form a stable contact with the ground, avoiding support suspension or uneven force due to uneven ground, and providing a stable erection benchmark for the electronic level.

[0013] 2. This invention, by setting up a fixing part, first excavates a foundation pit at the monitoring point that matches the size of the connecting plate and connecting disc, and places the connecting plate and connecting disc as a whole into the foundation pit; then, the operator rotates the connecting rod one clockwise, and the connecting plate and connecting disc rotate synchronously through the rod body transmission. The centrifugal force generated during the rotation will throw out several limiting rods two on the connecting disc, so that they initially contact the inner wall of the foundation pit; then, the connecting rod one is quickly rotated in the opposite direction, and the reverse torque is used to make the thrown limiting rods two clamped to the inner wall of the foundation pit; finally, the reverse rotation torque is continuously applied to drive the limiting rods two to further penetrate into the surrounding soil, completing the fixing of the anchoring mechanism, thereby achieving deep anchoring of the bottom of the hinged rod to the ground, greatly enhancing the connection strength between the bottom of the hinged rod and the ground, and effectively avoiding support displacement caused by soft ground or external disturbance.

[0014] 3. This invention, by setting up a storage section, allows the operator to rotate handle two before unfolding the hinge rod. The rotation of the handle drives the threaded rod to rotate synchronously. As the threaded rod rotates, its limiting contact with the extension rod gradually disengages, giving the extension rod freedom of movement. Subsequently, the operator pulls the hinge rod outward. During this process, hinge blocks four, five, six, and seven move in sync with the displacement of the hinge rod. Simultaneously, the hollow rod and the extension rod adaptively tilt and retract to match the unfolding trajectory of the hinge rod. After the hinge rod is unfolded to the preset distance, the operator rotates handle two in the opposite direction, driving the threaded rod to reset and re-engage with the extension rod, locking the unfolded state of the hinge rod. This achieves controllable unfolding of the hinge rod, allowing adjustment of the unfolding distance and avoiding the problem of uncontrolled distance during unfolding of traditional hinge structures. This ensures that the erection posture of the support mechanism meets the benchmark requirements for monitoring operations.

[0015] 4. This invention, by setting up a protective part, allows the operator to place the fixing plate and protective cover onto the support rod after the support rod is completed and press it down. The fixing plate slides down along the outer wall of the support rod, simultaneously driving the adapter plate one towards the connecting ring. Before pressing down, the sliding ring is pressed down first, causing the sliding ring to move the adapter plate two downwards. The adapter plate two moves in conjunction with the connecting rod and stretches the spring two. After the connecting rod is completely disengaged from the adapter plate two, the fixing plate is rotated, causing the adapter plate one to rotate synchronously on the connecting ring, so that the adapter plate one and the adapter plate two are precisely engaged. Then the sliding ring is released, and the stretched spring two drives the sliding ring and the connecting rod to return to their original position. After the connecting rod returns to its original position, it is embedded in the engagement gap between the adapter plate one and the adapter plate two, firmly limiting and locking the two, completing the stable installation of the protective cover. It accompanies the monitoring operation throughout the process to protect the monitoring device. The protective cover can effectively shield the device from sun and rain, preventing temperature drift and short circuits caused by temperature and humidity fluctuations in the core components of the monitoring device, and preventing dust from clogging the sensor interface, thus avoiding monitoring errors caused by environmental factors from the source.

[0024] The protective part 5 includes a fixing plate 511 sleeved on the outer wall of the support rod 111. A connecting ring 512 is fixedly connected to the outer wall of the support rod 111. Several adapter plates 513 are fixedly connected to the bottom of the fixing plate 511, and adapter plates 514 are fixedly connected to the top of the connecting rings 512. The adapter plates 513 are respectively adapted to the adapter plates 514. A limiting member 2 is provided on the support rod 111. Four adapter plates 513 and four adapter plates 514 are provided. Both adapter plates 513 and adapter plates 514 are L-shaped. The limiting member 2 includes a sliding ring 515 slidably connected to the outer wall of the support rod 111. The top of the sliding ring 515 is fixedly connected to the outer wall of the support rod 111. The device has several connecting rods 516, which pass through the corresponding adapter plate 1 513 and adapter plate 2 514.

[0026] In use, first open the hinge rod 214. Before opening, turn handle 2 418. When handle 2 418 turns, threaded rod 417 will also turn. As threaded rod 417 rotates, it will disengage from extension rod 416. At this time, pull open the hinge rod 214. When pulling the hinge rod 214, hinge blocks 411, 412, 413, and 414 will move in coordination with the movement of hinge rod 214. During the movement, hollow rod 415 and extension rod 416 will tilt and contract to coordinate with the movement of hinge rod 214. After determining the opening distance, turn handle 2 418 in the opposite direction to make threaded rod 417 limit extension rod 416 again, thereby achieving the effect of opening the hinge rod 214. After unfolding, adjust the extension of the slide bar 221 according to the actual ground conditions to adapt to uneven ground. To adjust, first pull the handle 226. While pulling, the limiting rod 223 will slowly disengage from the limiting groove 222. As the fixing ring 224 moves, the spring 225 will be stretched. After the limiting rod 223 is completely disengaged from the limiting groove 222, pull the slide bar 221 to adjust its extension length. After adjustment, release the handle 226. The spring 225 will then return to its original position along with the fixing ring 224 and the limiting rod 223, thus achieving adaptability to various ground surfaces. Then, dig a hole in the ground the same size as the connecting plate 314 and the connecting disc 325, and then connect the connecting plate 314 and the connecting disc 325. The disc 325 is placed into the hole. After placement, the connecting rod 313 is rotated clockwise. At this time, the connecting plate 314 and the connecting disc 325 will rotate. During rotation, centrifugal force will throw out several limiting rods 322. After being thrown out, the connecting rod 313 is quickly rotated in the opposite direction. At this time, the limiting rods 322 will be stuck in the inner wall of the hole. Then, the connecting rod 313 is rotated in the opposite direction with force to make the limiting rods 322 penetrate deeper into the soil. This can improve the grip of the bottom of the hinge rod 214 on the ground and prevent displacement due to insufficient grip. After supporting the support rod 111, the protective cover 518 is installed on the outer wall of the monitoring device 112. During installation, the fixing plate 511 and the protective cover 518 are put on the support rod 111, and then... When pressed, the fixed plate 511 slides on the outer wall of the support rod 111, bringing the adapter plate 513 into contact with the connecting ring 512. After contact, the fixed plate 511 is rotated. Before contact, the sliding ring 515 needs to be pressed down, causing the adapter plate 514 to move downwards. As the adapter plate 514 moves, the connecting rod 516 moves, and the spring 517 is stretched. After the connecting rod 516 disengages from the adapter plate 514, the fixed plate 511 is rotated. The fixed plate 511 then brings the adapter plate 513 to rotate on the connecting ring 512. The rotation of the adapter plate 511 and the adapter plate 513 causes the adapter plate 513 to engage with the adapter plate 514. Then, the pressure on the sliding ring 515 is released.At this point, spring 517, along with sliding ring 515 and connecting rod 516, will return to its original position. As connecting rod 516 moves, it can bind adapter plate 513 and adapter plate 514 together, thus achieving the installation effect of protective cover 518. Protective cover 518 can then protect monitoring device 112, allowing monitoring device 112 to be activated for inspection of the building.
