Description

Technical Field

[0001] This utility model relates to the field of dam early warning technology, and in particular to a leakage location and early warning device for power plant reservoir dams. Background Technology

[0002] The power plant reservoir dam leakage location and early warning device is a monitoring system that integrates sensing technology, data analysis, and intelligent early warning. It is specifically designed to detect dam seepage in real time and accurately locate the leakage point, ensuring the safe operation of the power plant reservoir. Its core function is to detect signs of leakage early through multi-parameter collaborative monitoring, preventing major accidents such as dam failure.

[0003] A piezometer is an instrument used to measure the pore water pressure in soil or rock. Common types include vibrating wire and piezoresistive types. Installation requires drilling, saturating permeable rock, burying the instrument at the target depth, backfilling with sand, and sealing the top. Data is collected via a cable-connected reading device to monitor water pressure changes. It is widely used in stability assessments of dams, slopes, and other engineering projects. During use, attention must be paid to the maintenance of the permeable rock and temperature compensation. It is an important component of reservoir dam leakage location and early warning systems.

[0004] However, the following problems were found in the implementation of the relevant technology: Piezometers are an essential device for dam leakage early warning systems. This device is usually equipped with a cable and buried underground for a long time. However, the area where the piezometer is buried may attract rodents to settle. When rodents move around in the cable burial area, there is a high probability that they will bite and damage the cable, causing great losses and affecting the normal use of the piezometer. In view of this, a power plant reservoir dam leakage location and early warning device is provided to overcome the above defects. Utility Model Content

[0036] Working principle:

[0037] When using this invention, the user should first insert the reagent tube 9 into the inner side of the placement groove 7 on the inner side of the protective sleeve 2 to fix the reagent tube 9. Then, the user should insert the fixing sleeve 10 into the inner side of the protective sleeve 2, ensuring that the contact groove 11 on the side of the protective sleeve 2 corresponds one-to-one with the reagent tube 9 placed in the inner side of the placement groove 7. Then, one side of the stop block 8 should contact both ends of the protective sleeve 2 and the fixing sleeve 10. Finally, glue should be used to attach one side of the stop block 8 to both the protective sleeve 2 and the fixing sleeve 10. One end of the 0 is fixed, and the protective sleeve 2 and the fixed sleeve 10 are connected together by the stop block 8, while ensuring that the reagent tube 9 will not fall off due to external force. Then, the fixing ring 15 is fixed to one side of the stop block 8, and the fixed sleeve 10 is gradually put onto the conveying cable 3 fixed to one end of the piezometer body 1. At the same time, a connecting ring 5 is placed between different fixed sleeves 10. The connecting ring 5 slides with the conveying cable 3, and one end of the piezometer body 1 is fixed with a fixed ring. When installing the fixing sleeve 10, the fixing ring 15, which is in contact with one side of the fixing block 4, is fixed to the fixing block 4 by glue or other means. Then, the user rotates the rotating block 13 located on the side of the connecting ring 5. The rotating block 13 is located inside the rotating groove 14, which is located on the side of the connecting ring 5. The rotating block 13 rotates with the rotating groove 14, and the rotating block 13 is fixed with the connecting bolt 12. The connecting bolt 12 also rotates with the connecting ring 5. The fixing ring 15 has a connecting hole 6 on one side, and the inner side wall of the connecting hole 6 is threaded. At this time, the user brings the fixing ring 15 close to the connecting bolt 12 and rotates the rotating block 13 at the same time. The rotation of the rotating block 13 drives the connecting bolt 12 to rotate, and thus drives the connecting bolt 12 to spiral with the connecting hole 6. In this way, the different fixing sleeves 10 and other components are connected together by the connecting bolt 12. In this way, by setting up a protective shell, the transmission cable 3 can be protected to a certain extent, avoiding problems caused by wild animals gnawing on the transmission cable 3.

[0038] In this utility model, the connecting bolt 12, reagent tube 9, fixing sleeve 10 and other components are all existing technologies, and their working principle is consistent with similar products on the market, so they will not be described in detail here.

[0039] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
