Description

Technical Field

[0001] The invention relates to the technical field of monitoring equipment, in particular to a water conservancy project dam safety monitoring device and a monitoring method. Background Art

[0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. Water conservancy projects require the construction of different types of hydraulic structures such as dams, dikes, spillways, sluices, water inlets, channels, ferries, rafts, fishways, etc. to achieve their goals; dams refer to water-blocking dikes such as dikes, reservoirs, and rivers that intercept rivers; general reservoir dams are mainly composed of main dams, auxiliary dams, normal spillways, emergency spillways, newly added emergency spillways, Lingzheng Channel culverts, etc. In order to ensure the safety of the dam, relevant personnel will install AI visual instruments on the dam to monitor the status of the dam.

[0003] In this regard, as disclosed in announcement No. CN217843375U, a reservoir dam safety status monitoring device comprises a mounting tube, a sliding rod is slidably installed in the mounting tube, a threaded groove is opened on the sliding rod, a threaded rod is threadedly installed in the threaded groove, and the bottom end of the threaded rod is rotatably connected to the bottom inner wall of the mounting tube; a first rotating shaft, the first rotating shaft is rotatably installed on the mounting tube, one end of the first rotating shaft is fixedly installed with a first bevel gear, and the other end is fixedly installed with a handwheel; the reservoir dam safety status monitoring device provided by it has the advantages of being able to adjust the height of the upright pole, facilitating the maintenance of components, and being conducive to safe maintenance.

[0004] The above technology discloses a reservoir dam safety status monitoring device, which uses a mounting plate to set up an AI visual instrument installed above the water body for safety monitoring. Through the provided hand wheel, mounting tube, slide rod, threaded rod, bevel gear and other structures, maintenance personnel can operate and adjust the height to facilitate subsequent non-height maintenance work. However, the following problems still exist during use:

[0005] 1. Although solar panels are installed for energy-saving power storage and supply, the environmentally friendly power storage effect is not ideal. The main reason is that during long periods of dark days or nights, the stable and environmentally friendly power storage is prone to occur, making it difficult to ensure the power storage effect. In addition, dust and impurities will inevitably accumulate on the top of the solar panels, resulting in reduced light transmission conversion and power storage effect. This is very restrictive and affects the stability of long-term power supply for detection work, making it difficult to provide long-term and stable power supply support without wiring. 2. After being lowered, monitoring instruments such as AI visual instruments are still located above the water body, making it inconvenient for personnel to perform safety inspections and maintenance directly on the dam. 3. On rainy or windy days, there is a lack of intelligent automatic safety protection for power storage structures such as solar panels. There is a risk of damage to the power storage structure due to debris or broken branches carried by rain or strong winds. The long-term safety of use is not ideal, and it is difficult to provide support for long-term safe use.

[0006] In order to solve the problems of unsatisfactory environmental protection power storage effect, inconvenience for personnel to carry out safety inspection and maintenance work directly on the dam, and lack of intelligent and automatic safety protection of power storage and power supply structures such as solar panels on rainy or windy days, we proposed a water conservancy project dam safety monitoring device and monitoring method to solve the above problems.
