Description

Technical Field

[0001] The utility model relates to the technical field of dam safety monitoring, in particular to a seepage pressure monitoring system. Background Art

[0002] With the continuous construction and development of water conservancy automation and informatization, the dam safety monitoring system has also developed vigorously.

[0003] At present, the main method of seepage pressure monitoring in the dam safety monitoring system is to drill a seepage pressure groove on the back water surface of the dam and install a piezometer for online monitoring. Generally, 6 to 12 seepage pressure monitoring points are designed according to the size of the dam. The piezometer is placed in the seepage pressure groove through a cable, and the cable is concentrated in a protection box. Since the piezometers are distributed in different positions of the dam, it is necessary to connect a long cable to the protection box. Considering the cable protection, the dam surface is generally excavated, the cable is buried below the dam surface, and then backfilled, resulting in a long construction period, high cost, and difficult maintenance in the later stage. At the same time, since the cable is generally tens to hundreds of meters away from the seepage pressure groove to the protection box, in thunderstorm weather, the cable can be easily affected by induced lightning, causing damage to equipment such as the protection box or the piezometer, and the cable is extremely susceptible to human or other forms of damage.

The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0026] See also Figures 1 to 3 , is a seepage pressure monitoring system in an embodiment of the utility model, which is applied to a reservoir dam 10. A seepage pressure groove is provided on the reservoir dam 10. The seepage pressure monitoring system includes a monitoring element 20 and a data acquisition component.

[0027] Wherein: an osmotic pressure measuring tube 11 is provided in the osmotic pressure tank, and the osmotic pressure measuring tube 11 is adapted to the osmotic pressure tank. Specifically, the outer wall of the osmotic pressure measuring tube 11 is in contact with the tank wall of the osmotic pressure tank, and the bottom of the osmotic pressure measuring tube 11 is in contact with the bottom of the osmotic pressure tank. The monitoring element 20 is located in the osmotic pressure measuring tube 11, and the monitoring element 20 is connected to the data acquisition component. The data acquisition component includes a Lora gateway 31 and a Lora terminal 32 that communicate with each other. The Lora terminal 32 is located above the monitoring element 20, and the Lora terminal 32 is connected to the monitoring element 20 through a connecting cable 40, so that the monitoring element 20 is suspended in the osmotic pressure measuring tube 11 through the connecting cable 40. When the monitoring element 20 implements monitoring of the osmotic pressure value of the reservoir dam 10, the osmotic pressure value collected by the corresponding monitoring element 20 can be collected through the Lora terminal 32, and the data processing received from the Lora terminal 32 through the Lora gateway 31 can be collected. Relevant data can be collected without wiring, which is beneficial to reducing the complexity and cost of the osmotic pressure monitoring construction of the reservoir dam 10.

[0028] It should be noted that the Lora gateway 31 is installed on the top of the reservoir dam 10. The Lora gateway 31 can receive the seepage pressure data collected by multiple Lora terminals 32 from the monitoring elements 20. At the same time, the Lora gateway 31 can also receive monitoring data such as rainfall, water level, and video, avoiding the existing way of installing the protection box on the back of the dam. It also solves the problem of needing to build a separate pole to monitor other elements, reducing the number of poles and stations on the reservoir dam 10.

[0029] It should be noted that a protection box 50 is provided on the reservoir dam 10, and the protection box 50 covers the notch of the seepage pressure tank and also covers the pipe mouth of the seepage pressure measuring tube 11. The protection box 50 and the seepage pressure tank are connected to form a closed space. The seepage pressure measuring tube 11, the connecting cable 40 and the Lora terminal 32 are all located in the closed space, wherein the seepage pressure measuring tube 11 is sleeved on the outside of the connecting cable 40 and the Lora terminal 32. It can be understood that through the provision of the protection box 50, the risk of the equipment being struck by lightning and human damage is effectively reduced, thereby improving the stability of the seepage pressure monitoring system.

[0030] In this embodiment, the Lora terminal 32 is installed in the protection box 50, and the antenna of the Lora terminal 32 is also arranged in the protection box 50, which can prevent the antenna from being damaged when it is outside the protection box 50. The Lora terminal 32 adopts IP68 design, so that the protection level of the Lora terminal 32 reaches IP68, so that when the protection box 50 is submerged, the Lora terminal 32 can continue to work normally. It should be noted that the Lora terminal 32 has a built-in lithium battery, which is used to provide power for the Lora terminal 32. In the absence of a solar charging panel and an external input power supply, data is collected once every 1 hour. The Lora terminal 32 can work for more than 5 years, and the lithium battery can be replaced later for continuous operation, realizing the low power consumption design of the Lora terminal 32, and the power consumption is less than 10uA@12V.

[0031] In this embodiment, the connecting cable 40 is a 4-core shielded hydraulic cable, and the monitoring element 20 is a vibrating-wire piezometer.

[0032] In this embodiment, the protective box 50 is made of engineering plastic material, which can enable the Lora terminal 32 and the Lora gateway 31 to communicate normally and ensure the stability of the Lora wireless transmission. Among them, the Lora gateway 31 has a built-in communication module, which is used to provide a wireless network. The Lora gateway 31 communicates with the Lora terminal 32 through the wireless network.

[0033] In the specific implementation, by connecting the monitoring element 20 with the Lora terminal 32, and communicating the Lora terminal 32 with the Lora gateway 31, when the monitoring element 20 monitors the seepage pressure value of the reservoir dam 10 in real time, the seepage pressure value collected by the corresponding monitoring element 20 can be collected through the Lora terminal 32, and the data processing received from the Lora terminal 32 through the Lora gateway 31 can be collected without wiring, which is beneficial to reducing the complexity and cost of the seepage pressure monitoring construction of the reservoir dam 10. At the same time, a protection box 50 is set on the reservoir dam 10, and the protection box 50 is used to cover the notch of the seepage pressure tank, and the protection box 50 and the seepage pressure tank are connected to form a closed space, and the connecting cable 40 and the Lora terminal 32 are located in the closed space to protect the Lora terminal 32, the connecting cable 40 and the monitoring element 20, which effectively reduces the risk of equipment being struck by lightning and human damage, and improves the stability of the seepage pressure monitoring system.

[0034] It should be noted that the above implementation process is only to illustrate the feasibility of the present application, but this does not mean that the seepage pressure monitoring system of the present application has only the above-mentioned implementation process. On the contrary, as long as the seepage pressure monitoring system of the present application can be implemented, it can be included in the feasible implementation plan of the present application.
