By acquiring real-time water level data, it provides a scientific basis for flood control scheduling, structural stability assessment, and disaster early warning. By monitoring water level change trends, abnormal rises and falls can be detected in a timely manner, and the risk of dam failure can be predicted.

[0003] The existing patent announcement number shows that the water level measuring component of the existing device is fixed to the end of a crossbar, which is suspended above the water. When it is inspected or replaced, personnel need to climb to the far end of the crossbar or use equipment such as boats or baskets to approach the device, which poses safety hazards such as falling from height and drowning. If calibration, cleaning or repair is required, the whole device must be disassembled, which is cumbersome and easy to cause secondary damage. It is difficult to meet the requirements of dams, reservoirs and other scenarios for reliable safety monitoring and convenient operation and maintenance.

[0004] To address the above issues, a water level measurement device for dam safety monitoring is proposed. Utility Model Content

[0025] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0027] Please see Figures 1-4 In this embodiment, a dam safety monitoring water level measuring device includes a column 1 and a crossbar 2 connected to one side of the column 1. A water level measuring component 3 is installed on the crossbar 2. A support frame 4 for supporting the crossbar 2 is installed on the column 1. A movable frame 5 for adjusting the movement of the water level measuring component 3 is installed on the column 1.

[0028] The water level measuring component 3 includes a movable frame 31 slidably connected to the crossbar 2 and a radar water level gauge 32 connected to the bottom of the movable frame 31. The radar water level gauge 32 is based on electromagnetic wave ranging technology. When electromagnetic waves encounter the water surface, they are reflected, and some of the energy returns to the radar sensor. It is a non-contact measurement with strong anti-interference ability. In actual use, the installation height of the radar water level gauge 32 is used to facilitate the subsequent calculation of the real-time water level.

[0029] The movable frame 5 includes a movable rod 51 connected to one side of the bottom of the movable frame 31 and an operating rod 52 connected to one end of the movable rod 51 away from the movable frame 31. A storage groove 12 for storing the operating rod 52 is provided on one side of the column 1. The top of the movable rod 51 is slidably engaged with the bottom of the crossbar 2. A through hole is provided on one side of the top of the storage groove 12 for the sliding of the operating rod 52 through the column 1. A fixing member for fixing the operating rod 52 in the storage groove 12 is connected to the column 1.

[0030] Using the above solution, by pulling the operating rod 52 to move the moving rod 51, the moving frame 31 can be moved and adjusted on the crossbar 2. There is no need for staff to climb to the end of the crossbar 2 away from the column 1 for operation, installation or maintenance. After the moving frame 31 moves to the end of the crossbar 2, the operating rod 52 can be fixed to the column 1 by the fixing parts. Then the operating support frame 4 supports the crossbar 2, improving the stability of the crossbar 2.

[0031] Please see Figure 3 and Figure 4 The fixing component includes a snap-fit ​​block 54 connected to the side of the operating lever 52 near the column 1. The storage groove 12 has a snap-fit ​​groove 13 that mates with the snap-fit ​​block 54 on one side. The outer wall of the column 1 is threaded with a fixing bolt 15. The snap-fit ​​block 54 is provided with a fixing hole corresponding to the fixing bolt 15. The outer wall of the column 1 is provided with a groove 14 for inserting the head of the fixing bolt 15.

[0032] When the snap-fit ​​block 54 is placed in the snap-fit ​​groove 13, the position of the snap-fit ​​block 54 can be fixed by the fixing bolt 15, thereby restricting the movement of the operating rod 52.

[0033] Please see Figure 3 The top of the movable rod 51 is connected to the T-shaped strip 55, and the bottom of the crossbar 2 is provided with a T-shaped groove for sliding the T-shaped strip 55. The T-shaped groove passes through the column 1.

[0034] The sliding fit between the T-slot and the T-bar 55 provides a limit, allowing the moving rod 51 to move horizontally stably.

[0035] Please see Figure 2The support frame 4 includes a mounting plate 41 and a diagonal brace 42 connected to one side of the mounting plate 41. The top end of the diagonal brace 42 is connected to a support seat 43 for supporting the crossbar 2. The support seat 43 is provided with a slot that cooperates with the moving rod 51. The mounting plate 41 is connected to the column 1 by mounting bolts 44.

[0036] Specifically, after the movable frame 31 is moved to the end of the crossbar 2 away from the column 1, the mounting plate 41 can be moved upward so that the support seat 43 supports the crossbar 2. By supporting the movable rod 51, bending is reduced. When the support seat 43 provides support, the mounting plate 41 is fixed to the column 1 by the mounting bolts 44, which can cover the groove 14 and reduce rusting.

[0037] Please see Figure 3 and Figure 4 Limiting blocks are connected to the inner walls on both sides of the movable frame 31. A solar panel 33 and a control box 34 are installed on the top of the movable frame 31. The solar panel 33 converts light energy into electrical energy and stores it in the battery in the control box 34. The control box 34 can be equipped with existing data processing modules and wireless modules for converting and transmitting data from the radar level gauge 32. This is prior art and not a specific improvement of this application, so it will not be described in detail here.

[0038] Please see Figure 4 The crossbar 2 has limiting grooves 22 on both sides for sliding of the limiting block, a wire groove 21 for placing cables at the bottom of the crossbar 2, a number of drainage holes communicating with the wire groove 21 on both sides of the crossbar 2, and a strip groove corresponding to the wire groove 21 at the top of the column 1.

[0039] Specifically, the drainage hole is designed to prevent rainwater from accumulating in the cable tray 21. When the moving frame 31 moves on the crossbar 2, the cable can move within the cable tray 21 and then be placed inside the cable tray 21.

[0040] Furthermore, the bottom of the column 1 is connected to the base 11; this facilitates the connection of the base 11 to the concrete base when the device is installed at the target location.

[0041] The working principle of this utility model is as follows: by pulling the operating rod 52, the moving rod 51 can be moved, and the moving frame 31 can be moved and adjusted on the crossbar 2. There is no need for the staff to climb to the end of the crossbar 2 away from the column 1 for operation, installation or maintenance. After the moving frame 31 moves to the end of the crossbar 2, when the locking block 54 is placed in the locking groove 13, the position of the locking block 54 can be fixed with the fixing bolt 15, thereby restricting the movement of the operating rod 52. The mounting plate 41 is moved up, so that the support seat 43 supports the crossbar 2. By supporting the moving rod 51, bending is reduced. When the support seat 43 supports the crossbar 2, the mounting plate 41 is fixed to the column 1 by the mounting bolt 44, which can cover the groove 14 and reduce rust. The support frame 4 supports the crossbar 2 and improves the stability of the crossbar 2.

[0042] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
