Abstract
Description
Technical Field
[0001] This utility model relates to the field of slope detection technology, and in particular to a slope strength detection device. Background Technology
[0002] Slope displacement or deformation is a precursor to its instability and failure. Therefore, developing a device that can sensitively and reliably detect changes in slope strength (i.e., deformation) has significant safety and economic value.
[0003] Currently, slope monitoring technologies mainly include geodetic methods, GNSS methods, inclinometer methods, and various physical sensor monitoring methods. Among them, the hydrostatic leveling system based on the principle of connecting pipes is used for high-precision relative settlement (i.e., vertical displacement) monitoring. The basic principle of this type of system is: multiple liquid tanks are connected by pipes and deployed at different points on the slope. Utilizing the natural contour of the liquid levels in the tanks, when settlement or uplift occurs at a certain point, the liquid level in that tank will change relative to the other tanks. By measuring this change in liquid level with high precision, the vertical displacement at that point can be calculated.
[0004] However, applying traditional hydrostatic leveling systems to field slope monitoring scenarios faces numerous challenges: poor adaptability to installation terrain: slope surfaces are often uneven and have varying gradients. Traditional devices typically have fixed mounting bases and sensors, making it difficult to achieve consistent initial installation heights for all connected liquid tanks on complex slopes. Even small errors in initial installation height can cause the initial liquid levels at different measuring points to differ, introducing systematic errors and severely impacting the monitoring accuracy of minute deformations (especially initial creep). Difficulty in sensor alignment: To ensure that the measuring axis of the level sensor (such as a magnetostrictive sensor) is strictly parallel to the direction of gravity, guaranteeing normal float operation and measurement accuracy, the sensor tank needs to be vertical. On uneven slopes, adjusting the verticality of each tank is extremely difficult, and the lack of effective fine-tuning mechanisms often leads to inconsistent sensor measurement benchmarks. Therefore, a slope strength detection device is proposed to address these issues. Utility Model Content
[0005] The purpose of this invention is to at least solve one of the aforementioned technical defects.
[0006] Therefore, one objective of this utility model is to propose a slope strength testing device to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.
[0007] To achieve the above objectives, one embodiment of the present invention provides a slope strength testing device, including a flange seat, a mounting seat, and an anchor rod. The mounting seat is detachably connected to one side of the flange seat, and the anchor rod is fixedly connected to the bottom of the mounting seat. The bottom end of the anchor rod is cone-shaped, and several guide rods are fixedly connected to the top of the mounting base; The outer surface of the guide rod is movably connected to the chassis, and the height of the chassis is adjustable; The outer surface of the guide rod is threaded with a lower washer, and the outer surface of the guide rod is threaded with a fastener; The lower pad is locked to the bottom surface of the chassis, and the fastener is locked to the top surface of the chassis; A ball sleeve is fixedly connected to the center of the top surface of the chassis, and a ball joint is movably connected inside the ball sleeve; The top of the ball joint is fixedly connected to the tank body; The angle of the tank is adjustable, and an interface is fixedly connected to the bottom of the side of the tank. The top of the tank is fixedly connected to the organism, and the front of the organism is fixedly connected to a communication port. The ball sleeve has fastening pins threaded on both sides, and the ends of the fastening pins abut against the ball joint.
[0008] Preferably, in any of the above embodiments, the flange seat is bent at a 90-degree angle, and the flange seat and the mounting base are provided with a plurality of aligned positioning holes.
[0009] The above technical solution employs the following internal components: a data acquisition circuit and a liquid level sensor. The liquid level sensor is housed within the tank. The specific structure of the data acquisition circuit and liquid level sensor includes: an electronic chamber, a magnetostrictive wire, a float, an electronic energy pickup mechanism, a signal processing circuit, and a communication port. The electronic chamber integrates both measurement and control circuits. The measurement circuit is responsible for sending a start pulse and receiving the return pulse generated by the magnetic float. The control circuit processes these pulse signals, converting them into a readable liquid level value.
[0010] Multiple units are deployed at the same height on the slope, with anchor bolts inserted vertically into the slope. These units are connected via interfaces and pipes, and the liquid levels inside the tanks are uniform. Any change in the liquid level at any point in the tank will be detected by the unit's structure and transmitted to the host computer via communication ports and cables. This indicates displacement or deformation of the slope at that location, signifying a change in its strength.
[0011] Magnetostrictive Wire (Waveguide Wire): The magnetostrictive wire is installed inside the measuring rod, which is typically a non-magnetic stainless steel tube. The magnetostrictive wire plays a crucial role in the measurement process; it serves as both the transmission medium for the pulse signal and the site where the magnetostrictive effect occurs. Float: The float contains a permanent magnetic field and floats up and down with changes in the liquid level. The magnetic field of the float interacts with the magnetic field in the magnetostrictive wire, producing the magnetostrictive effect. Electronic Energy Pickup Mechanism: The electronic energy pickup mechanism senses the torsion of the magnetostrictive wire caused by the magnetostrictive effect and converts it into a corresponding current pulse. Signal Processing Circuit: The signal processing circuit receives the current pulses from the electronic energy pickup mechanism and calculates the time difference between the two pulses. This time difference has a definite mathematical relationship with the liquid level value, allowing for the calculation of the accurate liquid level value. Communication Interface: The acquisition circuit also includes a communication port for transmitting the measured liquid level value to external devices or systems. Common communication ports include RS485.
[0012] Preferably, in any of the above solutions, the mounting base is welded to the anchor rod, and the anchor rod is made of stainless steel.
[0013] Preferably, in any of the above embodiments, the guide rods are arranged in a circumferential array about the axis of the chassis, and the lower pad is a hexagonal nut.

[0015] Preferably, in any of the above solutions, the body and the tank are connected by screws.
[0016] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows: This slope strength testing device, once deployed, allows for fine-tuning of the tank's height. The chassis is movably connected to the guide rod, and the top and bottom of the chassis are secured with pads and fasteners, allowing for height adjustment after deployment. Adjusting the ball joint allows for angle adjustment of the tank, and tightening the fastening pin allows for angle adjustment after deployment. This device, through its height and angle fine-tuning capabilities, ensures precise equalization of the liquid levels inside the tanks within the same group of devices, significantly improving the accuracy of subsequent testing. In slope strength testing, even minute changes in liquid level can reflect slope displacement or deformation. Precise equalization of liquid levels ensures timely and accurate capture of these changes, providing reliable data for slope stability assessment.

[0022] like Figure 1-4 As shown, this slope strength testing device includes a flange seat 1, a mounting seat 2, and an anchor rod 3. The mounting seat 2 is detachably connected to one side of the flange seat 1, and the anchor rod 3 is fixedly connected to the bottom of the mounting seat 2. The bottom end of the anchor rod 3 is cone-shaped, and several guide rods 4 are fixedly connected to the top of the mounting base 2; The outer surface of the guide rod 4 is movably connected to the chassis 5, and the height of the chassis 5 is adjustable. The outer surface of the guide rod 4 is threaded with a lower washer 6, and the outer surface of the guide rod 4 is threaded with a fastener 7. The lower pad 6 is locked to the bottom surface of the chassis 5, and the fastener 7 is locked to the top surface of the chassis 5; A ball sleeve 8 is fixedly connected to the center of the top surface of the chassis 5, and a ball joint 9 is movably connected inside the ball sleeve 8; The top of the ball joint 9 is fixedly connected to the tank body 10; The angle of the tank body 10 is adjustable, and an interface 11 is fixedly connected to the bottom of the side of the tank body 10. The top of the tank 10 is fixedly connected to the body 12, and the front of the body 12 is fixedly connected to the communication port 13; The ball sleeve 8 has fastening pins 14 threaded on both sides, and the ends of the fastening pins 14 abut against the ball joint 9.
[0023] Example 1: Flange seat 1 is bent at a 90-degree angle, and several aligned positioning holes are provided on flange seat 1 and mounting base 2. Mounting base 2 is welded to anchor rod 3, which is made of stainless steel. Guide rod 4 is arranged in a circumferential array about the axis of chassis 5, and the lower washer 6 is a hexagonal nut. Fastener 7 is specifically a hexagonal nut with washer, and the top of ball joint 9 is thermally connected to tank body 10. Ball joint 9 is made of plastic. Body 12 and tank body 10 are connected by screws.
[0024] Example 2: The internal structure of the body 12 includes a data acquisition circuit and a liquid level sensor, wherein the liquid level sensor is inserted into the tank 10. The specific structure of the data acquisition circuit and the liquid level sensor is as follows: electronic chamber, magnetostrictive wire, float, electronic energy pickup mechanism, signal processing circuit, and communication port 13. Electronic chamber: The electronic chamber integrates a measurement circuit and a control circuit. The measurement circuit is responsible for sending a start pulse and receiving the return pulse generated by the magnetic float. The control circuit is responsible for processing these pulse signals and converting them into a readable liquid level value.
[0025] Multiple devices are deployed at the same height on the slope, with anchor bolts 3 inserted vertically into the slope. The multiple devices are connected through interface 11 and pipes, and the liquid levels inside tank 10 are at the same height. When the liquid level in tank 10 changes at any point, it will be detected by the structure of the body 12 and sent to the host computer through communication port 13 and cable. This indicates that the slope has shifted or deformed at that point, and the strength has changed.
[0026] Example 3: When conducting stability monitoring on a slope in a mountainous area, this slope strength testing device was deployed.
[0027] First, based on the slope topography and monitoring requirements, multiple installation points at equal heights are selected on the slope. Flange seat 1 is installed at the selected locations, ensuring its 90-degree bend design meets installation requirements and that the positioning holes on mounting base 2 are aligned. Mounting base 2 is then detachably connected to flange seat 1 using bolts and other connectors. Next, stainless steel anchor rods 3 are vertically inserted into the slope. The bottom of anchor rod 3 is tapered for easy insertion, and it is securely welded to mounting base 2. After installation, the height and angle of the device are adjusted. The height of the base plate 5 is adjusted using the lower pad 6 on the outer surface of the guide rod 4 and the fasteners 7, ensuring the base plate 5 is in the appropriate position. Then, the movement of the ball joint 9 within the ball sleeve 8 is adjusted using the fastening pins 14 on both sides of the ball sleeve 8, thereby adjusting the angle of the tank 10. After multiple fine-tuning adjustments, the liquid levels inside the tanks 10 of the same group of devices are precisely equal. Multiple devices are connected via interfaces 11 and pipes, ensuring that the liquid levels inside the tanks 10 are interconnected and initially at the same height. The machine body 12 is connected to the tank 10 by screws. The liquid level sensor inside the machine body 12 enters the tank 10 to begin real-time monitoring of the liquid level. During the monitoring process, if any displacement or deformation occurs at a certain point on the slope, causing a change in the liquid level in the tank 10, the liquid level sensor will immediately detect the change. The acquisition circuit will process the signal and send it to the host computer via communication port 13 and cable. The staff can then understand the changes in slope strength in a timely manner based on the signal received by the host computer and take appropriate measures.
[0028] The working principle of this utility model is as follows: Anchor rod 3 is inserted vertically into the slope. The device is securely installed on the slope using the detachable connection between flange seat 1 and mounting base 2. Mounting base 2 is welded to anchor rod 3 to ensure a firm connection. Anchor rod 3 is made of stainless steel, which has good corrosion resistance and strength.
[0029] Height and Angle Adjustment: The guide rod 4 on the top of the mounting base 2 is used for height adjustment of the chassis 5. The guide rod 4 is arranged circumferentially about the axis of the chassis 5. The chassis 5 is locked at a suitable height via the lower pad 6 (hexagonal nut) on the outer surface of the guide rod 4 and the fastener 7 (hexagonal nut with washer). The ball sleeve 8 at the center of the top surface of the chassis 5 is movably connected to the ball joint 9. The top of the ball joint 9 is fixedly connected to the tank 10. The fastening pins 14 on both sides of the ball sleeve 8 can adjust the contact force with the ball joint 9, thereby adjusting the angle of the tank 10. Through these adjustments, the liquid levels inside the tanks 10 of the same device can be precisely equalized, laying the foundation for subsequent accurate testing.
[0030] Liquid Level Detection and Signal Transmission: The body 12 contains a data acquisition circuit and a liquid level sensor, which is installed inside the tank 10. Its specific structure includes an electronic chamber, a magnetostrictive line, a float, an electronic energy pickup mechanism, a signal processing circuit, and a communication port 13. The measurement circuit integrated in the electronic chamber emits a starting pulse. The magnetic float moves along the magnetostrictive line with the liquid level change, generating a return pulse, which is received by the measurement circuit. The control circuit processes these pulse signals and converts them into a readable liquid level value. When the liquid level changes at any point in the tank 10, it indicates that the slope has shifted or deformed, and its strength has changed. After the liquid level sensor detects the change, the data acquisition circuit processes the signal and transmits it to the host computer via the communication port 13 and a cable, achieving real-time monitoring of slope strength changes.
[0031] Compared with the prior art, the present invention has the following advantages: This slope strength testing device, once deployed, allows for fine-tuning of the height of the tank 10. The base 5 is movably connected to the guide rod 4. The top and bottom of the base 5 are secured with pads 6 and fasteners 7, respectively, enabling adjustment of the tank 10's height after deployment. Adjusting the ball joint 9 allows for adjustment of the tank 10's angle. Finally, tightening the fastening pin 14 allows for adjustment of the ball joint 9's angle after deployment. This device, through its height and angle fine-tuning functions, ensures precise equalization of the liquid levels inside the tanks 10 within the same group of devices, significantly improving the accuracy of subsequent testing. In slope strength testing, even minute changes in liquid level can reflect slope displacement or deformation. Precise equalization of liquid levels ensures timely and accurate capture of these changes, providing reliable data for slope stability assessment.
