AI Technical Summary
In existing technologies, water level changes are observed through regular inspections, which can lead to untimely flood discharge operations from reservoirs and cause property damage.
A water volume monitoring device was designed, which utilizes a guide tube, a hollow sphere, a conical counterweight, a pin, a lifting plate, a copper sheet, and a buzzer. As the water level rises, the hollow sphere rises, and the conical counterweight, under the influence of gravity, causes the pin to enter the mounting component. When the lifting plate falls, it triggers the copper sheet to contact the electrode, thus issuing an alarm.
It enabled timely warnings when water levels reached the warning position, preventing reservoir discharge and reducing property damage.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of reservoir engineering, and more specifically, to a water quantity monitoring device for reservoirs. Background Technology
[0002] A reservoir is generally defined as a "water conservancy structure for flood control, water storage, and water flow regulation, which can be used for irrigation, power generation, flood control, and fish farming." Reservoirs are typically classified by their capacity, such as small, medium, and large. Water level monitoring devices are essential components of any reservoir.
[0003] In existing technologies, water level changes are mostly observed through regular inspections, which makes it difficult to make timely responses. This can affect the normal flood discharge operation of the reservoir, leading to flood discharge and property damage.
[0004] Therefore, a water volume monitoring device for reservoirs is provided to solve the above problems. Summary of the Invention
[0005] The purpose of this utility model is to address the problem that in existing technologies, most water level changes are observed through regular inspections, which makes it difficult to formulate timely response plans, thereby affecting the normal flood discharge operation of the reservoir, resulting in flood discharge and subsequent property damage.
[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:
[0007] A water volume monitoring device for a reservoir includes an installation component. A fixing component is fixedly connected to one side of the installation component. A guide tube is snapped into the bottom of the installation component. A water inlet groove is formed on the outer side wall of the bottom end of the guide tube. A barrier net is fixedly connected to the inner side wall of the bottom end of the guide tube. The upper surface of the barrier net and the lower surface of the installation component are fixedly connected to the same slide rail. A hollow sphere is slidably snapped into the inner side wall of the slide rail. A locking rod is fixedly connected to both ends of the hollow sphere. The locking rod is slidably snapped into the slide rail. A conical counterweight is fixedly connected to one end of the locking rod. A pin is fixedly connected to the top end of the conical counterweight.
[0008] As a preferred technical solution of this application, the inner side of the mounting component is movably connected to a rotating shaft, and a lifting plate is fixedly connected to it through the rotating shaft. A copper sheet is fixedly connected to one end of the lifting plate.
[0009] As a preferred technical solution of this application, the lower surface of the mounting component is provided with through holes adapted to the ejector pin inside the guide tube, and the lower surface of the lifting plate is provided with grooves adapted to the ejector pin on both sides.
[0010] As a preferred technical solution of this application, the fixing member has a battery slot inside, and a power supply battery is provided inside the battery slot. Electrodes are movably snapped onto the inner sidewalls on both sides of the battery slot and the inner bottom wall of the mounting member, and one end of each of the two electrodes is welded with a wire.
[0011] As a preferred technical solution of this application, a buzzer is fixedly installed on the upper surface of the fixing member, and one end of each of the two wires is respectively welded to the power supply electrode of the buzzer.
[0012] As a preferred technical solution of this application, a snap-fit groove is provided on one side of the lower surface of the fastener, and a bolt is threadedly connected to one side of the upper surface of the fastener, with a washer sleeved at the bottom end of the bolt.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] In the scheme of this application:
[0015] By incorporating a guide tube, hollow sphere, conical counterweight, ejector pin, lifting plate, copper sheet, and buzzer, the device allows the hollow sphere to rise due to the increase in water level and buoyancy during operation. Meanwhile, the conical counterweight, under the influence of gravity, keeps its smaller end pointing upwards, allowing the ejector pin to enter the mounting component through the through-hole. The ejector pin then lifts one end of the lifting plate via a groove, causing the other end to fall, bringing the copper sheet into contact with the electrode. This energizes the buzzer, triggering an alarm to indicate that the reservoir water level has reached the warning level. This solution addresses the problem of existing technologies that rely on periodic inspections to monitor water level changes, making timely responses difficult and potentially disrupting normal reservoir discharge operations, leading to flooding and property damage.
