[0002] Water level monitoring is the foundation of water conservancy safety. There are many types of water level monitoring devices, which can be mainly divided into two categories according to their working principle: contact type and non-contact type. Among them, ultrasonic / radar water level gauges are commonly used non-contact monitoring devices for river water level monitoring. Their principle is: to emit sound waves or radar waves to the water surface and receive the echoes, and to determine the water level by calculating the round-trip time of the beam.

[0003] Routine maintenance of river radar level gauges is crucial for ensuring their long-term stable operation and data accuracy. Routine maintenance includes cleaning the surface of the radar level gauge, removing impurities such as dust, bird droppings, and cobwebs. The cleaning cycle varies from weekly to monthly. However, the existing support for river radar level gauges is fixed, and the gauge extends above the river via the support, making cleaning and maintenance extremely inconvenient. Therefore, this paper proposes a water level monitoring device for water conservancy safety monitoring. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figures 1-4 In this embodiment of the utility model, a water level monitoring device for water conservancy safety monitoring includes a column assembly 1, an adjustable support assembly 2, and a radar water level gauge 3. The column assembly 1 and the adjustable support assembly 2 form a bracket that provides support for the radar water level gauge 3. The column assembly 1 includes a fixed column 101, a central rod 102, a top block 103, and a bearing 105. The fixed column 101, the central rod 102, and the top block 103 are connected and fixed in sequence from bottom to top, and the bearing 105 is installed on the outside of the central rod 102. Adjustable support assembly 2 includes a rotating cylinder 201 and a support frame 202. The radar level gauge 3 is fixedly installed on one side of the rotating cylinder 201 through the support frame 202. The rotating cylinder 201 is distributed between the fixed column 101 and the top block 103 and is rotatably installed on the outside of the bearing 105. The rotating cylinder 201 can rotate around the central rod 102, which is used to rotate the radar level gauge 3 to the upper part of the river or from the upper part of the river to the bank, so as to facilitate the cleaning and maintenance of the radar level gauge 3. The upper and lower ends of the rotating cylinder 201 are respectively fixed with a top ring block 203 and a second flange 204. The outer diameter of the top ring block 203 is smaller than the outer diameter of the top block 103 and fits against the bottom of the top block 103. A first flange 104 is fixed to the top of the fixed column 101. The outer diameter of the first flange 104 is smaller than that of the second flange 204 and fits against the bottom of the second flange 204. The first flange 104 and the second flange 204 have relatively aligned fixing holes. Fixing bolts 4 pass through the fixing holes and are tightened with nuts to fix the position of the radar level gauge 3.

[0016] In this embodiment: During routine use, the water level monitoring device is tightened by passing the fixing bolts 4 through the fixing holes on the first flange 104 and the second flange 204 and tightening them with nuts (e.g. Figure 1 / 2), which can achieve stable support for radar level gauge 3, so that radar level gauge 3 can remain stable above the river channel; When cleaning and maintenance of the radar level gauge 3 is required, the fixing bolts 4 can be removed and the adjustable support assembly 2 can be rotated as a whole, so that the radar level gauge 3 can be rotated from above the river to the bank. This makes it easier for staff to access the radar level gauge 3 with climbing tools (such as ladders) to carry out cleaning operations. After cleaning, the adjustable support assembly 2 can be reset and fixed with the fixing bolts 4. The operation is simple and convenient, which can effectively improve the work efficiency of cleaning and maintenance of radar level gauge 3.

[0017] Please refer to this carefully. Figures 3-4 A sealing groove 5 is provided on the end face where the top block 103 and the top ring block 203 and the second flange 204 and the first flange 104 fit together, and a sealing ring 6 is installed on the inner side of the sealing groove 5.

[0018] In this embodiment, the sealing ring 6 is designed to maintain a good seal between the top block 103 and the top ring block 203, as well as between the second flange 204 and the first flange 104. This ensures a good sealing environment for the inner cavity of the rotating cylinder rod 201, allowing the bearing 105 to maintain a stable operating state for a long time.

[0019] Please refer to this carefully. Figures 1-3 Multiple annularly distributed extension rods 205 are fixed to the outer side of the second flange 204, and annular handles 206 are fixed to the outer side of the multiple extension rods 205.

[0020] In this embodiment, the ring handle 206 with a larger outer diameter makes it easier to grip and rotate, making operation easier.

[0021] Please refer to this carefully. Figures 1-4 The extension rods 205 are distributed at an angle downwards from the inside out; The top of the second flange 204 is formed with a conical water groove 207, and the bottom surface of the conical water groove 207 is inclined from the inside to the outside. The top of the extension rod 205 is provided with a drainage guide groove 209 that passes through the annular handle 206 and communicates with the conical water trough 207; The top of the inner wall of the conical water tank 207 is fixed with a protruding ring seat 208 that is aligned with and connected to the mounting hole. The top horizontal height of the protruding ring seat 208 is higher than the top horizontal height of the second flange 204. The fixing bolt 4 passes through the protruding ring seat 208 from top to bottom.

[0022] In this embodiment: when it rains, when rainwater falls into the conical water trough 207, it can be discharged through the channel formed by the conical water trough 207 and the drainage guide trough 209, which can reduce the phenomenon of rainwater seeping down from the edge of the second flange 204 into the gap between the second flange 204 and the first flange 104. At the same time, the structure of the protruding ring seat 208 keeps rainwater away from the contact surface between the fixing bolt 4 and the protruding ring seat 208, thereby reducing the phenomenon of rainwater seepage inside the fixing hole.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
