Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to seepage safety monitoring technical field, especially a seepage pressure water level measuring device. BACKGROUND
[0002] At present, dam seepage pressure automatic monitoring technology mainly adopts pressure sensing type (such as vibrating wire type, static pressure type), laser ultrasonic ranging type, optical fiber sensing type, small float type and other ways. However, the application status of the prior art in the industry is not optimistic, and the data of automatic monitoring shows the general problems of inaccuracy, instability and low data availability, which cannot provide effective data support for dam safety analysis and decision management. The reasons are as follows:
[0003] The pressure sensing monitoring method (such as vibrating wire type, static pressure type, etc.) can calculate the seepage pressure by sensing the pressure when the sensor is put into the bottom of the pressure measuring pipe. However, this method is affected by factors such as analog signal amplification processing technology, sand deposition, and sensitivity decline, resulting in data drift, large error, poor stability, and the need for high operation and maintenance. The laser acoustic wave measurement method is easily affected by environmental factors such as the curvature of the pressure measuring pipe, pipe wall corrosion, and pipe humidity, which cannot guarantee the stability and accuracy of the measurement data. The data accuracy of the optical fiber monitoring method is low, the error is large, and the stability is poor. The small float type monitoring method is prone to float jamming due to the problems of long and uneven curvature of the pressure measuring pipe, pipe wall corrosion, etc., resulting in monitoring failure. In addition, the traditional monitoring site power supply and data transmission are mainly through laying cables and signal lines. However, due to frequent lightning in the reservoir area, the system is often struck by lightning, resulting in system paralysis.
[0004] The dam seepage pressure automatic monitoring technology mainly uses static pressure sensors, among which the vibrating wire type sensor is more commonly used. However, long-term practice shows that the existing technology not only has high investment and maintenance, but also cannot meet the requirements of dam monitoring and seepage pressure automatic monitoring management in terms of data accuracy and stability after long-term operation. Therefore, the existing dam seepage pressure automatic monitoring technology and equipment cannot meet the needs of reservoir engineering management, which has become a serious problem in the industry management.

[0025] Reference manual attached Figure 1 The diagram shows a structural schematic of a seepage pressure water level measuring device provided in an embodiment of the present invention.
[0026] This utility model provides a device for measuring seepage pressure water level, including:
[0027] Pressure testing tube, probe 1, connecting wire 2, drive module 3, rotating wheel 4, storage battery 5, external power supply 6, and base 8.
[0028] The base 8 is positioned above the water level to be measured, the pressure measuring tube is vertically positioned below the base 8, the rotating wheel 4 is fixed above the base 8, one end of the rotating wheel 4 is fixedly connected to the connecting line 2, the connecting line 2 is wound around the rotating wheel 4, and the other end of the connecting line 2 is fixedly connected to the probe 1. When the rotating wheel 4 rotates, the probe 1 moves downward through the inside of the pressure measuring tube under the action of gravity to contact the water surface. The drive module 3 includes a motor and a controller, which are used to drive the rotating wheel 4 to rotate. The battery 5 is charged and discharged through an external power supply 6, and the battery 5 supplies power to the motor.
[0029] In one possible implementation, the probe 1 has a built-in wireless communication module, which is wirelessly connected to the controller.
[0030] In one possible implementation, the connection cable embeds a data cable and connects the controller and the probe to enable data transmission.
[0031] Furthermore, the connection between the pressure measuring tube and the base 8 is located at the center of the base 8.
[0032] Furthermore, the external power supply 6 is powered by a solar panel or mains electricity.
[0033] Furthermore, it also includes a communication module 7, which records and sends the rotation angle of the wheel 4 to the mobile terminal via a wireless connection.
[0034] The mobile terminal can also be a computer or a server, etc.
[0035] like Figure 2 As shown, the working process of the seepage pressure level measuring device in this embodiment is as follows:
[0036] S1, the rotating wheel 4 is powered by a motor to complete the rotation operation. According to the data sent by the probe 1 received by the controller, the rotating wheel 4 drives the connecting line 2 to rise or fall.
[0037] S2. When probe 1 first contacts the water level, the rotor 4 stops rotating and transmits the number of rotations n to the mobile terminal through the communication module.
[0038] S3. Calculate the elevation change of probe 1:
[0039] h=n·2πR
[0040] Where h is the distance that probe 1 moves on the vertical line, R is the radius of wheel 4, and the water level in the pressure measuring tube is Hh, i.e. Hn·2πR, where H represents the horizontal height of wheel 4 before it rotates.
[0041] The seepage pressure level measurement device provided in this embodiment addresses the common problems of low data accuracy, poor stability, and poor data availability in automatic monitoring of dam safety seepage pressure, especially for traditional technologies such as vibrating wire, pore static pressure injection, and small float types. This device offers a highly efficient and reliable solution to address the shortcomings of traditional pressure monitoring systems, such as large data errors, data drift, poor stability, and high maintenance requirements over long periods. Utilizing an inductive water level detection principle combined with a unique water level tracking function, it accurately determines water level changes, effectively overcoming the common drawbacks of electronic water level gauges like submersible, ultrasonic, and radar gauges, such as measurement instability and susceptibility to environmental influences, thus significantly improving data stability. The device also employs an ultra-low power consumption circuit design, operating in a low-power state most of the time. Combined with a high-efficiency lithium battery pack, this enables 2-3 years of maintenance-free operation. Furthermore, with a solar power system, year-round maintenance-free reliable operation can be ensured.
