Technical Field

[0001] The present invention relates to the technical field of river (dike) bank slope monitoring, and particularly to a one - pole - through monitoring device. Background Art

[0002] River (dike) bank slope monitoring is a crucial disaster prevention and mitigation measure. Its core lies in realizing the dynamic assessment of bank slope stability and disaster warning through real - time data collection and analysis. This work can not only effectively prevent sudden collapse accidents and ensure the safety of people's lives and property along the river (river), but also provide important basis for the scientific decision - making of water conservancy project operation and maintenance and the ecological protection of the river (dike) bank. By establishing an intelligent monitoring and warning system, it is possible to change from passive emergency rescue to active prevention and control, and minimize the losses and treatment costs of flood disasters. With the continuous innovation of intelligent perception monitoring technology in the new era, the accuracy and timeliness of this work will continue to improve, providing strong support for building a safe and resilient living environment.

[0003] River (dike) bank slopes are affected by many factors such as water flow scouring, sudden rise and fall of water levels, etc. Their stability is closely related to river water level changes, soil temperature and humidity of the bank slope, as well as soil settlement changes and bank slope displacement.

It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0019] Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention may be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.

[0020] Example 1, as Figure 1-7As shown in the figure, the present invention provides a one - pipe through monitoring device, including a steel bar base 1. An equipment protection box 2 is placed on the top of the steel bar base 1. Clamping plates 33 are provided on both sides of the equipment protection box 2.

[0021] The effect achieved by the entire Example 1 is that this device is divided into a data module and a sensing and perception module. The data module is installed inside the device protection box 2.

This module supports collaborative acquisition and data fusion of multiple sensors, has edge preprocessing capabilities, and realizes low-power operation through intermittent sampling and sleep mechanisms to ensure the battery life of the device, providing a high-quality raw data basis for subsequent data transmission and analysis.

The screw sleeve 14 is threadedly connected to the flower tube 5. O-ring 15s are installed on the inner sides of the top ends of the screw sleeve 14 and the measuring tube 19.

Fixed blocks 27 are fixed to the four ends of the equipment protection box 2. Rotating blocks 28 are rotatably connected inside the fixed blocks 27. An installation frame 29 is fixed to one end of the rotating block 28. The solar panel 3 is installed in the installation frame 29 through a second bolt 30. A second motor 31 is installed at one end of the fixed block 27. The output end of the second motor 31 penetrates through one side of the fixed block 27 and is fixed to the rotating block 28. A protective cover 32 is fixed to the outside of the second motor 31 at one end of the fixed block 27.

[0023] The effect achieved by the entire Embodiment 2 is that through the setting of the solar panel 3, the effect of self-power supply can be achieved, which is green and environmentally friendly. This device has multi-sensor fusion, and a single device integrates multiple types of sensors such as a soil temperature and soil humidity module 8, a magneto-dilatometer main body 6, and an inclinometer 7, breaking through the limitations of traditional single-point acquisition, sharing a power supply / communication / processing unit, reducing the device volume and installation complexity. The design of "one pole through" replaces distributed maintenance with single-point maintenance, saving the cost of device management and maintenance, and enhancing environmental adaptability. Through the operation of the first motor 2001, the bidirectional screw 2002 is driven to rotate, causing the two moving plates 2003 to move towards or away from each other under the limitation of the limit posts 2004, thereby driving the second connecting plates 2006 connected by the two first connecting plates 2005 to move towards or away from each other, and then being able to drive the two clamping plates 33 connected by the two groups of second connecting plates 2006 to move towards or away from each other, so as to be able to perform clamping, installation, and disassembly processing on the device protection box 2 as a whole. And through the setting of the clamping blocks 24, when the two clamping plates 33 move towards each other, the two clamping blocks 24 will be clamped at both ends of the device protection box 2, and the device can be limited while being clamped, making the clamping more stable and the practicability stronger. Through the operation of the second motor 31, the whole rotating block 28 can be driven to rotate, thereby driving the solar panel 3 installed in the mounting frame 29 to rotate, enabling it to be adjusted at a certain angle according to the position of the sun in the sky, with stronger practicability. And through the setting of the second bolt 30, the solar panel 3 can be installed and disassembled at any time, facilitating its replacement and maintenance, with stronger practicability. Through the setting of the protective cover 32, the second motor 31 can be protected from being eroded and damaged by external rainwater. Through the setting of the inclined groove 21, and the opening at the outer end of the inclined groove 21 is at the bottommost end of the inclined opening, it can prevent external rainwater from entering the steel bar base 1 through the inclined groove 21, with higher safety. Through the setting of the first bolt 26, the top cover 25 can be installed and disassembled, facilitating the maintenance of the electronic control components installed inside the device protection box 2, with stronger practicability. Through the setting of the mounting sleeve 22, it is convenient to install the magneto-dilatometer main body 6.

[0024] Working principle: When the device is in use, the steel bar base 1 is installed on the ground, while the measuring tube 19 and the filter tube 5 are buried underground. The magnetostrictive settlement gauge body 6 is used for settlement measurement, and the soil temperature and soil humidity module 8 is used for soil temperature and humidity measurement. They are coaxial in structure, cleverly combined together, and the mutual interference is reduced to the lowest acceptable level. This design is different from the independent structures of both in the market. The measuring tube 19 is divided into multiple pipe segments, which are independent of each other. The pipe segments can be directly connected to each other and are serially connected according to the measurement depth. The circuits of each pipe segment and the internal measurement modules are connected by the MODELBUD bus to ensure that multiple pipe segments can be connected. The pipe segments are connected by threads and sealed with an O-ring 15. The measuring tube 19 section is an independent individual with good sealing effect and can be soaked in water for a long time. The above-ground equipment and the equipment protection box 2 and all the underground measuring tubes 19 are of an integrated one-piece structure, different from the conventional scattered measurement units. The sensor lines of this device are separated to avoid parallel laying and keep a certain distance as much as possible to reduce electromagnetic coupling. The single-point grounding or multi-point grounding method is adopted, which is selected according to the specific circuit structure and electromagnetic environment. Different sensors and devices should be connected to the same grounding plane to avoid interference current caused by grounding potential difference. If multiple sensors work in the same system, the time-division multiplexing method can be adopted to let them perform data acquisition and transmission in different time slices to avoid electromagnetic interference generated when working simultaneously. When selecting sensors, products with good electromagnetic compatibility are preferred. These sensors have passed strict electromagnetic compatibility tests and can work stably in a complex electromagnetic environment. By the operation of the first motor 2001, the bidirectional screw 2002 is driven to rotate, so that the two moving plates 2003 move towards or away from each other under the limitation of the limiting posts 2004, thereby driving the second connecting plates 2006 connected by the two first connecting plates 2005 to move towards or away from each other, and then being able to drive the two clamping plates 33 connected by the two groups of second connecting plates 2006 to move towards or away from each other, so as to be able to perform clamping, installation and disassembly processing on the overall equipment protection box 2. And through the setting of the clamping blocks 24, when the two clamping plates 33 move towards each other, the two clamping blocks 24 will be clamped at both ends of the equipment protection box 2, and the clamping can be limited while clamping, making the clamping more stable and more practical. By the operation of the second motor 31, the whole rotating block 28 can be driven to rotate, so that the solar panel 3 installed in the mounting frame 29 can be driven to rotate, so that it can be adjusted at a certain angle according to the position of the sun in the sky, which is more practical. And through the setting of the second bolt 30, the solar panel 3 can be installed and disassembled at any time, which is convenient for replacement and maintenance and is more practical. By the setting of the protective cover 32, the second motor 31 can be protected to avoid being eroded and damaged by external rainwater. Through the setting of the inclined groove 21, and the opening at the outer end of the inclined groove 21 is at the bottom of the inclined opening, it can avoid external rainwater from entering the steel bar base 1 through the inclined groove 21, with higher safety.
