Description

Technical Field

[0001] This utility model relates to the field of water level monitoring technology, specifically to a flood season water level monitoring and warning device. Background Technology

[0002] Flood season water level monitoring and warning devices are used to monitor changes in the water level of rivers, lakes, and other water bodies in real time and issue early warning signals. During the flood season, increased rainfall causes river levels to rise, easily leading to floods that pose a serious threat to people's lives and property. Therefore, timely and accurate monitoring of water level changes and issuing early warnings are of great significance in effectively preventing and mitigating the impact of floods.

[0003] Currently, during the flood season, a large amount of debris, such as aquatic plants and plastic bags, floats on the water surface. This debris can block or interfere with the propagation path of ultrasonic signals. When ultrasonic signals encounter these debris, they may be reflected, scattered, or absorbed, resulting in a weakening of the received signal strength or a change in the waveform, which in turn affects the accuracy of monitoring and increases monitoring errors. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a flood season water level monitoring and warning device, which can effectively block debris from entering the monitoring range of the ultrasonic water level gauge and affecting the detection accuracy through the blocking cover, so as to solve the problems mentioned in the background art.

The blocking cover is divided into two parts, consisting of an upper cover and a lower cover. An installation cylinder is installed at the end of the upper cover away from the lower cover. A partition is installed inside the installation cylinder, and a through hole is provided at the center of the partition. The ultrasonic water level gauge is installed in the installation cylinder, and the monitoring end of the ultrasonic water level gauge extends into the blocking cover through the through hole. Multiple inlet and outlet ports are provided on the outer ring surface of the lower cover. Multiple actuating plates with a ring structure are also installed on the outer ring surface of the lower cover.

[0006] As a preferred technical solution, a connecting sleeve is installed at the end of the lower cover away from the mounting cylinder, and the other end of the connecting sleeve is fitted onto the outside of the lower cover. The inner ring surface of the connecting sleeve is provided with a connecting groove of an annular structure, and a connecting ring is slidably installed in the connecting groove. The inner ring of the connecting ring is installed on the outer ring surface of the lower cover.

[0007] As a preferred technical solution, the opening of the mounting cylinder is threaded with a cylinder cover that presses the ultrasonic level gauge tightly, and the center of the cylinder cover is provided with a wiring hole that communicates with the mounting cylinder.

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0019] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, this utility model discloses a flood season water level monitoring and warning device, which includes an ultrasonic water level gauge 10 and a blocking cover. The blocking cover is divided into two parts, consisting of an upper cover 1 and a lower cover 2. An installation cylinder 6 is installed at the end of the upper cover 1 away from the lower cover 2. A partition 11 is installed inside the installation cylinder 6, and a through hole 12 is provided at the center of the partition 11. The ultrasonic water level gauge 10 is installed in the installation cylinder 6, and the monitoring end of the ultrasonic water level gauge 10 extends into the blocking cover through the through hole 12. Multiple inlet and outlet ports 3 are provided on the outer ring surface of the lower cover 2, and multiple actuating plates 4 evenly distributed in a ring structure are also installed on the outer ring surface of the lower cover 2.

[0020] In this embodiment, a connecting sleeve 5 is installed at one end of the lower cover 2 away from the mounting cylinder 6, and the other end of the connecting sleeve 5 is sleeved on the outside of the lower cover 2. The inner ring surface of the connecting sleeve 5 is provided with a connecting groove of an annular structure, and a connecting ring 13 is slidably installed in the connecting groove. The inner ring of the connecting ring 13 is installed on the outer ring surface of the lower cover 2.

[0021] In this embodiment, a cylinder cover 7 is threadedly connected to the opening of the mounting cylinder 6 to press the ultrasonic level gauge 10 tightly, and a wiring hole communicating with the mounting cylinder 6 is provided at the center of the cylinder cover 7.

[0022] The ultrasonic level gauge can be removed directly outwards along the mounting cylinder after the cap is unscrewed. Conversely, after installation, the cap can be tightened to press and fix the ultrasonic level gauge in place. This method facilitates the assembly and disassembly of the ultrasonic level gauge.

[0023] In this embodiment, a horizontal plate 8 is installed on the outside of the mounting cylinder 6. A fixing ring 9 is installed at one end of the horizontal plate 8. The fixing ring 9 has multiple fixing holes. A support column can be inserted into the fixing ring, and a bolt can be passed through the fixing hole to connect with the support column. The support column can be installed on the riverbank, while the blocking cover is located on the surface of the river.

[0024] In this embodiment, the shield is arranged in a conical structure, so that the shield is smaller at the top and larger at the bottom, so as to ensure that the ultrasonic water level gauge has a large monitoring range.

[0025] In this embodiment, filter screens are installed in both the inlet and outlet 3. The filter screens can effectively intercept debris entering the lower cover body, thus avoiding the impact of debris on the accuracy of monitoring.

[0026] In this embodiment, the shield is made of high-strength plastic material, which reduces weight and cost.

[0027] One end of the lower cover enters the water, allowing outside water to enter the interior of the lower cover through the inlet and outlet. Debris in the water is intercepted by the filter screen. Because a deflector plate is installed on the outside of the lower cover, it can be pushed when debris and water flow through, causing the lower cover to rotate along the connecting ring, thereby pushing away the surrounding debris and preventing debris from accumulating around the lower cover. The barrier effectively intercepts debris from entering the monitoring range of the ultrasonic water level gauge and affecting the monitoring accuracy.

[0028] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto.
