Description

Technical Field

[0001] The present application relates to the technical field of foundation settlement detection, and in particular to a foundation settlement detection device. Background Art

[0002] Ground subsidence, a widespread natural phenomenon, has diverse causes, including both natural geological changes and human activities such as underground resource extraction and large-scale construction. This phenomenon not only threatens the integrity of infrastructure but can also lead to structural instability in areas of land subsidence, potentially posing a range of safety hazards. Therefore, accurate and efficient monitoring of ground subsidence is crucial for assessing ground stability and guiding infrastructure design and maintenance.

[0003] To address this need, foundation settlement detection devices have emerged. Their core components typically consist of a sturdy tripod and a sophisticated detector. The tripod, serving as a supporting base, is constructed from high-strength, corrosion-resistant materials to adapt to complex and changing installation environments, ensuring the continuity and reliability of detection work. The detector integrates sensors, a data processing unit, and a display unit to form a complete monitoring system. The sensors are responsible for capturing minute displacement changes in the foundation and instantly transmit this critical data to the data processing unit for in-depth analysis and precise calculations. Finally, the processed results are intuitively presented on the display unit, allowing operators to quickly understand the foundation settlement status.

[0004] However, in practice, especially near intersections with frequent heavy traffic, ground vibrations are frequent and intense, posing a significant challenge to the stability of foundation settlement detection equipment. Ground vibrations can cause slight wobbling of the tripod, which in turn affects the accuracy of the sensor, leading to deviations in monitoring data and reduced reliability of test results, leaving room for improvement. Summary of the Invention

[0005] The purpose of this application is to provide a foundation settlement detection device to solve the problem that when the above-mentioned detection device is used at an intersection with frequent vibrations, its own stability may be affected, thereby causing deviations in the detection data.

[0006] The present application provides a foundation settlement detection device that adopts the following technical solution: A foundation settlement detection device comprises a horizontally arranged support plate, a detector rotatably mounted on the side surface of the support plate, and four support rods hinged to the four side edges of the support plate, wherein the support rods are provided with locking members for fixing the rotation angle of the support rods, and the lengths of the support rods can be adjusted and fixed; positioning rods with adjustable lengths are hinged on the outer peripheries of the four support rods, and fasteners for fixing the rotation angle of the positioning rods are installed; the positioning rods can be rotated downward to a vertical state, and the positioning rods in the vertical state can be flush with the lower end of the support rod after the length is adjusted.

[0007] By adopting the above technical solution, when the detection device is used in an environment with frequent vibrations, the four positioning rods can be rotated downward to a vertical state, and then the length of the positioning rods can be adjusted so that the lower ends of the positioning rods also contact the ground. In this way, the four positioning rods are used to synchronously provide auxiliary support for the detection device, thereby improving the stability of the detection device when used in this environment and reducing the possibility of it tipping over or overturning.

[0008] Optionally, a universal wheel is hingedly connected to the end of the positioning rod away from the support rod.

[0009] By adopting the above technical solution, when the positioning rod needs to move a short distance, due to the setting of the universal wheel at the end of the positioning rod, the support rod whose lower end originally abuts the ground can be shortened as a whole. At this time, the universal wheels at the lower ends of the four positioning rods abut against the ground, which facilitates the short-distance movement of the detection device.

[0010] Optionally, the detector is rotatably connected to a base plate on the side close to the support plate, and protruding blocks are fixed on the four edges of the base plate. A limit block and an elastic extrusion piece are slidably provided on the upper edge of the support plate, and a limiting notch is provided on the side of the limit block facing the detector; the elastic extrusion piece is used to drive the limit block to slide in the direction close to the detector, so that the protruding block is stuck in the limiting notch; a guide rod is fixed on the side of the limit block away from the detector, and a traction piece is provided on the outer periphery of the support rod to drive the guide rod to slide in the direction away from the protruding block.

[0011] By adopting the above technical solution, after the detector is installed on the support plate, under the action of the elastic extrusion part, the limit block slides in the direction close to the protruding block until the protruding block is stuck in the upper limit notch of the limit block, thereby locking the protruding blocks on the four sides of the detector at the same time, realizing the assembly and fixation of the detector and the support plate; the detector can also be quickly disassembled later by the action of the traction part.

[0012] Optionally, the elastic extrusion member includes a first compression spring and a guide plate fixed on the support plate, the guide plate is provided with a guide hole for the guide rod to pass through, and the two ends of the first compression spring are respectively fixedly connected to the side surfaces of the guide plate and the limit block close to each other.

[0013] By adopting the above technical solution, the elastic extrusion part utilizes the elastic force of the first compression spring and is guided by the guide plate and the guide hole so that the limit block can slide stably and automatically toward the direction close to the detector, ensuring that the protruding block can be accurately inserted into the limit notch, thereby realizing the rapid and stable installation of the detector. At the same time, the structure is simple and the operation is reliable.

[0014] Optionally, the traction member includes a traction rope, an elastic reset member and a traction rod slidably arranged on the outer periphery of the support rod, and the length directions of the traction rod and the support rod are parallel; the two ends of the traction rope are respectively fixedly connected to the side surfaces of the guide rod and the traction rod close to each other; the elastic force of the elastic reset member is smaller than the elastic force of the elastic extrusion member, and the elastic reset member is used to drive the traction rod to slide in a direction away from the support plate.

[0015] By adopting the above technical solution, a traction rope is used to connect the guide rod and the traction rod, and combined with an elastic reset part, the traction rod maintains a tendency to slide away from the support plate under normal circumstances, but the elastic force is smaller than the elastic extrusion part, ensuring that the limit block can be unlocked by simply pulling the traction rod when needed, thereby achieving rapid disassembly of the detector, easy operation and without affecting the overall stability of the device.

[0016] Optionally, the elastic return member includes a second compression spring in a compressed state, a guide plate fixed on the outer periphery of the support rod, and a baffle fixed on the traction rod, the baffle being located on the side of the guide plate away from the support plate, and the two ends of the second compression spring are respectively fixedly connected to the sides of the baffle and the guide plate that are close to each other.

[0017] By adopting the above technical solution, when the limit block needs to be unlocked, the operator only needs to gently pull the traction rod to overcome the elastic force of the second compression spring, causing the traction rod to slide away from the support plate. The traction rope then drives the guide rod and the limit block to move, achieving rapid disassembly of the detector. This design is not only simple in structure and easy to implement, but also stable and convenient to operate, effectively improving the efficiency and flexibility of the foundation settlement detection device. At the same time, due to the moderate elastic force of the second compression spring, it can not only ensure the stable position of the traction rod under normal conditions, but also be easily pulled when needed, providing a good user experience.

[0018] Optionally, a traction block is hingedly connected to the end of the traction rod away from the support rod, and the rotating surface of the traction block is perpendicular to the axis of the traction rod; a positioning protrusion is fixed on the outer periphery of the positioning rod, and the positioning rod can be rotated to a state parallel to the length direction of the support rod and fixed; when the positioning rod is rotated to a state parallel to the length direction of the support rod, force is applied to slide the traction rod in the direction away from the support plate, and the side of the positioning protrusion away from the support rod can abut against the side of the folded traction block, and in this state, the limit block releases the lock on the protruding block.

[0019] By adopting the above technical solution, when the positioning rod is rotated to a position parallel to the length of the support rod, the staff can apply force to slide the traction rod away from the support plate. At this time, the folded side of the traction block can abut against the side of the positioning protrusion away from the support rod. This design not only provides an intuitive indication and limit for the sliding of the traction rod, but also ensures that in this state, the limit block can smoothly release the lock on the protrusion block, keeping the limit block unlocked, and realizing the quick and safe disassembly of the detector.

[0020] Optionally, a protective curtain is provided above the support plate to protect the upper part of the detector, the positioning rod can be rotated upward to an inclined state, and the outer edge of the protective curtain is detachably connected to the upper edges of several positioning rods in a vertical upward state.

[0021] By adopting this technical solution, when the positioning rods are rotated upward to an inclined position, the outer edge of the protective curtain can be detachably connected to the upper edges of the multiple vertical positioning rods, forming a stable protective cover that effectively blocks external interference with the detector, such as direct sunlight, rain, and dust accumulation. This design not only improves the detector's operating stability and data accuracy, but also extends its service life.

[0022] Optionally, a hook is fixedly provided on the outer periphery of the protective curtain, and a limiting hole for the hook to be engaged is opened on the positioning protrusion.

[0023] By adopting this technical solution, the hooks fixed to the outer periphery of the protective curtain match the limiting holes provided in the positioning protrusions. Simply snapping the hooks into the limiting holes securely connects the protective curtain to the positioning rod, forming a complete protective cover. This hook-to-limiting hole connection method is not only simple and easy to implement, but also stable and unlikely to fall off, effectively enhancing the protective effect of the protective curtain. This design also facilitates user disassembly and reassembly, allowing the position and status of the protective curtain to be easily adjusted according to actual needs, further enhancing the product's flexibility and practicality.

[0024] Optionally, the end of the positioning rod away from the hinged support rod can be detachably connected to the outer circumference of another support rod.

[0025] By adopting the above technical solution, when the detection device is used in areas with frequent vibrations or strong winds, the installation state of the positioning rod can be adjusted, and the overall assembly stability of the four support rods can be enhanced by using the positioning rod to connect the two opposite support rods.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. When the detection device is used in an environment with frequent vibrations, the four positioning rods can be rotated downward to a vertical state, and then the length of the positioning rods can be adjusted so that the lower ends of the positioning rods also contact the ground. In this way, the four positioning rods are used to simultaneously provide auxiliary support for the detection device, thereby improving the stability of the detection device when used in this environment and reducing the possibility of it tipping over or overturning.

[0027] 2. After the detector is installed on the support plate, the elastic extrusion member slides the limit block toward the protruding block until the protruding block is inserted into the upper limit notch of the limit block, thereby locking the protruding blocks on the four sides of the detector at the same time, thereby achieving assembly and fixation of the detector and the support plate; the detector can also be quickly disassembled later by the traction member.

The end of the positioning rod 41 away from the support rod 31 is hinged with a universal wheel 43 with a brake pad; when the positioning rod 41 needs to move a short distance, the support rod 31 whose lower end is originally in contact with the ground can be shortened as a whole.
