[0019] The following will clearly and completely describe the present invention with reference to the drawings and embodiments:

[0020] As Figures 1 to 3 shown, a water level monitoring device for water conservancy and hydropower of the present invention includes a support rod 1, and a mounting frame 2 is vertically arranged on the support rod 1, wherein the mounting frame 2 can be movably adjusted relative to the support rod 1 in the vertical and horizontal directions so as to flexibly adjust the position of the water level monitoring radar 3 to meet the water level monitoring requirements in different periods and improve the accuracy of water level monitoring; the water level monitoring radar 3 is installed at one end of the mounting frame 2 away from the support rod 1, and the water level monitoring radar 3 uses a millimeter wave radar; a pulling assembly is arranged between the mounting frame 2 and the support rod 1 to provide auxiliary support for the mounting frame 2 and ensure the stability of the mounting frame 2.

[0021] Furthermore, a motor-driven threaded lead screw is provided inside the support rod 1. The motor is located in the cavity at the bottom of the support rod 1. A slider 4 is arranged on the threaded lead screw. An adjustment slot 5 is formed on the support rod 1. The mounting bracket 2 is movably connected to the slider 4 through the adjustment slot 5. By controlling the forward and reverse rotation of the threaded lead screw by the motor, the up-and-down movement of the mounting bracket 2 is realized, thereby completing the adjustment of the water level monitoring radar 3 in the height direction. Among them, in this embodiment, the mounting bracket 2 is preferably arranged in a U-shaped structure, and the support rod 1 is located in the hollow channel in the middle thereof. Convex blocks 6 are arranged at one end of the slider 4 close to the mounting bracket 2. After the convex blocks 6 extend out of the adjustment slot 5, guide wheels 7 are rotatably arranged at both the upper and lower ends thereof. Accommodation grooves 8 are formed on both opposite inner side walls of the mounting bracket 2. Chute grooves 9 communicating with the accommodation grooves 8 are arranged at the upper and lower ends of the mounting bracket 2. The guide wheels 7 are slidably located in the chute grooves 9. A circular groove is formed in the middle of the guide wheel 7 along the circumferential direction, so that the guide wheel 7 can be clamped on the chute groove 9, and the side wall of the chute groove 9 is located in the groove, realizing the support and guidance of the guide wheel 7 for the mounting bracket 2.

[0022] Furthermore, an L-shaped mounting plate 10 is arranged on the convex block 6. The mounting plate 10 is arranged above the convex block 6. A positioning rod 12 is elastically arranged on the mounting plate 10 through a spring 11. A positioning hole matching the positioning rod 12 is arranged on the guide wheel 7. Both the positioning rod 12 and the positioning hole are non-circular structures. Preferably, the cross-section of the positioning rod 12 is arranged as a polygon with an included angle such as a triangle or a quadrilateral, so as to limit the guide wheel after the positioning rod 12 is inserted into the positioning hole, ensuring the stability of the position of the adjusted mounting bracket 2.

[0023] Furthermore, the pulling assembly includes a pulling rope 13 with one end connected to the mounting bracket 2. The pulling rope 13 can be made of steel wire rope. A fixing rod 14 for tying the pulling rope 13 is arranged at one end of the mounting bracket 2 away from the support rod 1. The other end of the pulling rope 13 is connected to a counterweight 16 after passing around a pulley 15 arranged on the support rod 1, so as to ensure that as the position of the mounting bracket 2 is adjusted, the counterweight 16 will move synchronously, making the pulling rope 13 in a tensioned state, playing a role in pulling the mounting bracket 2. Preferably, the counterweight 16 is slidably connected to the support rod 1, providing guidance for the movement of the counterweight 16 and avoiding the situation that the counterweight 16 shakes under external force.

[0024] Furthermore, the bottom of the support rod 1 is hinged with auxiliary support rods 17, and a plurality of auxiliary support rods 17 are arranged at intervals along the circumferential side of the support rod 1. The auxiliary support rods 17 can provide stable support for the support rod 1 to ensure the stability of the support rod 1. In addition, in this embodiment, a solar panel 18 is provided on the support rod 1, and the solar panel 18 supplies power to the water level monitoring radar 3 and the motor through a storage battery; in addition, a camera 19 electrically connected to the storage battery is also provided on the support rod 1 for monitoring the water surface condition to facilitate intuitive analysis of the actual water level condition; a control box 20 with a cloud acquisition terminal integrated therein is also provided on the support rod 1 for acquiring the information transmitted by the water level monitoring radar 3; at the same time, a satellite communication system is additionally installed at the top of the support rod 1, which can transmit the monitored water level data to the big data cloud platform in real time; since these systems and control devices are all relatively maturely applied in the prior art, they will not be elaborated herein.

[0025] When the present utility model is working, when it is necessary to adjust the water level monitoring radar 3 in the height direction, only need to start the motor to drive the threaded lead screw to rotate; when it is necessary to adjust the water level monitoring radar 3 in the horizontal direction, pull the positioning rod 12 to make the positioning rod 12 disengage from the limit of the guide wheel 7, and after the adjustment is in place, reset the positioning rod 12 to complete the positioning of the guide wheel 7. The structure is simple, the operation is simple and fast, and the practicability is strong.
