Description

Technical Field

[0001] The invention belongs to the technical field of water conservancy projects and relates to an automatic water conservancy monitoring device for water conservancy projects. Background Art

[0002] In water conservancy management departments, in order to remotely grasp the on-site hydrological data, various sensor devices are generally installed on-site. Each sensor device transmits the collected data remotely through wired or wireless means. Relevant management personnel can intuitively grasp various on-site hydrological data through their smartphones or PCs without going to the site, which provides favorable data support for the formulation of relevant measures.

[0003] Although the existing hydrological detection sensor device has certain hydrological data collection and transmission functions, it is limited by the structure and can generally only collect the water level and flow rate on site. In this way, the collected data is relatively simple and cannot allow remote related personnel to understand more data, which will more or less have a certain adverse impact on the safety of water conservancy equipment. The main disadvantages are as follows: First, since it is impossible to collect the water level difference between two areas on a horizontal plane, when a river or other area is blocked by floating objects, resulting in the upstream water level being too high and the downstream water level being too low, there is a possibility that the upstream water level will overflow the embankment and submerge the upstream farmland and buildings (for example, at the corner of the riverbed, the water flow is slow, and large floating bodies from the upstream continue to flow to this place). Second, since it is impossible to collect river water turbidity data, when factories discharge illegally or flash floods occur upstream, the relevant remote staff cannot understand the situation and deal with it in time, which will cause certain safety threats to residents or farmland and buildings along the river. Third, the existing hydrological detection sensor devices are generally powered by solar power generation and on-site installation of small water flow generators. The installation of water flow generators requires matching mounting frames and buoyancy equipment. The above installation methods have the problems of high cost and inconvenient installation, which have more or less caused certain adverse effects on the application of hydrological detection sensor devices. Fourth, it is impossible to detect the deformation data of the dam. In this way, when the dam is deformed due to various reasons, the relevant personnel cannot take timely countermeasures, which will also cause certain safety threats to the residents or farmland and buildings along the river. In summary, it is particularly necessary to have a water conservancy monitoring system that can effectively detect the water level data, water turbidity data, and whether the dam is deformed between the upstream and downstream of a horizontal plane, and can also conveniently obtain electricity through water flow. Summary of the invention

[0004] In order to solve the technical problems existing in the above-mentioned background technology, the present invention provides an automatic water conservancy monitoring device for a water conservancy project, including: an observation frame, four cable supports, a steel wire rope, a main sliding rod top cover, a main sliding rod, a sliding suspension frame, a water quality measuring instrument, and a buffering energy absorbing device. The water quality measuring instrument mounting base is fixed on the outer periphery of the sliding suspension frame, and a buoy is installed on the upper and lower plate connecting steel bars of the sliding floating frame, and the sliding suspension frame is sleeved on the main sliding rod, and the upper and lower ends of the sliding suspension frame are also each sleeved with a buffering energy absorbing device made of a multi-layer adhesive foam rubber material, the main sliding rod is upright fixed to the measured point through the bottom base, the main sliding rod top cover is installed on the top of the main sliding rod, and three cable supports are dispersedly fixed around the main sliding rod, and are connected to the cable connecting rod at the upper end of the main sliding rod top cover by steel wire for stability.

[0005] The water quality measuring instrument is equipped with a total of 4 distributed special-shaped floats; each distributed special-shaped float has the same shape, including a left-side special-shaped float and a right-side special-shaped float that are symmetrical on both sides, and the surfaces of the left-side special-shaped float and the right-side special-shaped float are arc-shaped surfaces. The lower end of the special-shaped float adopts a wedge-shaped form. On the one hand, it can ensure that the detection system is less resistant in the initial stage of entering the water. At the same time, the wedge shape can ensure that when the detection system enters the water, the buoyancy provided by the float shows an approximately linear growth trend, avoiding the adverse effects on the stability of the detection system when entering the water due to sudden changes in buoyancy around. Similarly, for the stage of the detection system leaving the water, the sudden change in buoyancy at the moment of the float leaving the water can be reduced to a certain extent, the amplitude of the uncertain variables that the control system needs to compensate can be reduced, the burden on the control system can be reduced, and a good response of the system can be ensured.

[0006] The core sensor of the detection mission payload adopts a low-noise vector sensor, which has an embedded geomagnetic sensor that can monitor in real time the changes in the heading angle of the vector sensor itself caused by the water flow.

[0007] The lower packaging body is provided with an upper cavity platform and a lower cavity platform which are isolated and sealed from each other; and a load placing stepping motor is fixed on the upper cavity platform of the lower packaging body.

[0008] The beneficial effects of the present invention are: The present invention provides an automatic water conservancy monitoring device for water conservancy projects, which can be installed and placed on the water surface for a long time, detect underwater targets through a load delivery system, and ensure short-term continuous tracking of underwater moving targets. In addition, it meets all-weather measurement requirements. Moreover, since the observation frame is firmly fixed and the upper and lower ends of the sliding suspension frame on which the measuring instrument is installed are provided with protective buffer energy absorption devices, when encountering extreme weather processes such as typhoons and cold waves during the real-time observation process, the present observation method can also effectively avoid the damage of the measuring instrument and the shoal or hydraulic structures due to rigid collision under the action of waves, thereby ensuring the all-weather continuity and safety of the measurement process, and the device is easy to carry, flexible and maneuverable, easy to use, safe and efficient, and has strong environmental adaptability.
