DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] Reference to embodiments in this text means that the specific features, structures, or characteristics described in connection with the embodiments can be included in at least one embodiment of the present utility model. The occurrence of this phrase at various positions in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0018] As Figure 1 shown, an embodiment of the present utility model provides a water level detection device for a water conservancy project, including a mounting frame 1 and three brackets 2 rotatably arranged on the side of the mounting frame 1. A first bolt 101 is provided at the rotational connection of each bracket 2 and the mounting frame 1, and a turning block 3 is hinged at the bottom of each bracket 2. A support frame 4 is rotatably connected to each turning block 3 by threads. After unfolding the three brackets 2 and adjusting the rotation angle, tighten the first bolt 101 clockwise so that the bracket 2 cannot rotate further. Then, according to the terrain, rotate the turning block 3 so that the bottom of the support frame 4 touches the ground, and adjust the height of the turning block 3 by rotating the support frame 4, thereby adjusting the height of the bottom end of the corresponding bracket 2 to ensure that the mounting frame 1 can maintain a horizontal state after the device is installed.

[0019] As Figure 1 and Figure 2 shown, in an embodiment of the present invention, it further includes four scale rods 5 and a connecting block 6 arranged between two adjacent scale rods 5. The scale rods 5 are slidably matched with the mounting frame 1, and two adjacent scale rods 5 are rotatably connected by the connecting block 6. Refer to Figure 4 , a limiting ball 16 is provided on the side wall of the connecting block 6. The limiting ball 16 is made of an elastic material, and two adjacent scale rods 5 are in interference connection through the limiting ball 16. Refer to Figure 1 , the scale rods 5 can be unfolded into a vertical state. A floating plate 7 is provided at the bottom end of the lowest scale rod 5. When the fixing of the bracket 2 and the mounting frame 1 is completed, the floating plate 7 is made to contact the water surface of the water body. When the liquid level rises or falls, the scale rods 5 will slide up or down accordingly, and the scale pointed to by the mounting frame 1 will also change accordingly. By simply reading the corresponding value on the scale rod 5, the detection of the water level can be completed.

[0020] As Figure 2 and Figure 3As shown, in the embodiment of the present invention, a shaft seat 11 is rotatably installed on the side wall of the bracket 2 in the middle position. A binding strap 12 is wound around the shaft seat 11. When the detection is completed and the three brackets 2 are retracted, the binding strap 12 can be pulled out from the shaft seat 11 and wound around the bracket 2 to realize the limit fixation of the bracket 2. Moreover, the mounting frame 1 is rotatably and penetratingly installed with a second bolt 8. When the device is retracted, the second bolt 8 is rotated clockwise. The second bolt 8 will contact the lowest scale rod 5 and limit it so that it cannot move up and down. A limit frame 13 is rotatably arranged at the top end of the highest scale rod 5. A buckle 14 is slidably arranged on the limit frame 13. And an elastic member 15 is arranged between the buckle 14 and the limit frame 13. The elastic member 15 adopts a spring. Refer to Figure 2 , rotate each scale rod 5 to make them fit together. Then rotate the limit frame 13 to sleeved on the top end of the scale rod 5. Cooperate with the buckle 14 and the limit frame 13 to limit and fix the scale rod 5 to prevent it from unfolding during the transfer process.

[0021] As Figure 2 shown, in the embodiment of the present invention, a level 9 and a lighting lamp 10 are also installed on the upper surface of the mounting frame 1. The setting of the level can show whether the mounting frame 1 is in a horizontal state when the device is installed, so as to facilitate the surveyor to adjust the positions of the mounting frame 1 and the bracket 2 to ensure that the mounting frame 1 is in a horizontal state, thereby achieving the purpose of improving the measurement accuracy. The design of the lighting lamp helps to observe and record data at night or in low-light conditions.

[0022] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and retouches can be made, and these improvements and retouches should also be regarded as the protection scope of the present utility model.
