DETAILED DESCRIPTION

[0022] The above scheme is further described below in conjunction with specific examples. It should be understood that these examples are used to illustrate the present application and are not limited to the scope of the present application. The implementation conditions adopted in the examples can be further adjusted according to the conditions of the specific manufacturer, and the implementation conditions not specified are usually the conditions in conventional experiments. Example 1

[0023] A water level detection device for a water conservancy project, such as Figure 1 and Figure 2 As shown, it includes a base 1, a fixed plate 2, a rotating shaft 3, a pull rope 4, a motor 5, a rotating member 6, a rotating cylinder 7, a counterweight 8 and an observation mechanism 9. The fixed plate 2 is connected to the left and right sides of the upper middle position of the base 1. The upper part of the fixed plate 2 is rotatably connected with the rotating shaft 3 through a damping sleeve. A pull rope 4 is wound on the rotating shaft 3, and scale lines are marked on the pull rope 4. The front upper part of the base 1 is connected to the motor 5, and the upper part of the output shaft of the motor 5 is connected to the rotating member 6. The rotating member 6 is rotatably connected to the base 1. A rotating cylinder 7 is rotatably connected between the left and right sides of the front of the rotating member 6. The other end of the pull rope 4 is wound on the rotating cylinder 7. The front lower part of the pull rope 4 is connected to the counterweight 8. The rear upper part of the base 1 is provided with an observation mechanism 9, through which the scale line at the junction of the pull rope 4 and the water surface can be clearly observed.

[0024] like Figure 1 and Figure 2 As shown, the observation mechanism 9 includes a fixing part 91, a display 92 and a rotating handle 93. The fixing part 91 is connected to the upper rear part of the base 1, the upper part of the fixing part 91 is rotatably connected to the display 92, the upper front part of the display 92 is connected to the rotating handle 93, and the front part of the base 1 is connected to a camera, the camera is located below the rotating part 6, the camera and the display 92 are electrically connected, and the camera and the display 92 are used to clearly observe the scale line at the junction of the pull rope 4 and the water surface.

[0025] The water level detection device of the water conservancy project is used to detect the water level of the water area. When in use, it is necessary to move the water level detection device of the water conservancy project to a boat, and then drive the boat to the surface of the water area to be detected, and then start the camera and the display 92 first, and then start the motor 5, and drive the rotating part 6 to rotate through the output shaft of the motor 5, so that the rotating cylinder 7, the pull rope 4 and the counterweight 8 rotate, so as to adjust the falling position of the counterweight 8, turn off the motor 5, and then rotate the rotating shaft 3 by hand so that the rotating shaft 3 lengthens the pull rope 4, and the rotating cylinder 7 also rotates under the action of friction, so that the counterweight 8 can sink into the water under the action of its own gravity. When the counterweight 8 contacts the bottom surface of the water area, it can be observed that the pull rope 4 has obvious signs of loosening. At this time, it is necessary to stop rotating the rotating shaft 3 immediately, and then use the camera to shoot the scale line at the junction of the pull rope 4 and the water surface and transmit it to On the display 92, people can zoom in and observe the scale lines on the pull rope 4 on the display 92, which is convenient for people to observe the water level. For easy viewing, people can also turn the rotating handle 93 by hand, so that the rotating handle 93 drives the display 92 to rotate, so as to get a better viewing angle. After recording the specific water level data, people turn the rotating shaft 3 in the opposite direction by hand, so that the rotating shaft 3 reels up the pull rope 4, so that the pull rope 4 pulls up the counterweight 8, and the counterweight 8 is pulled out of the water. Under the action of friction, the rotating cylinder 7 rotates in the opposite direction, and then the motor 5 is started again. Driven by the output shaft of the motor 5, the rotating member 6 rotates in the opposite direction to reset, so that the rotating cylinder 7, the pull rope 4 and the counterweight 8 rotate in the opposite direction to reset, and then turn off the motor 5, turn off the camera and the display 92, and transport the water level detection device of the water conservancy project back to the shore by ship. Example 2

[0026] On the basis of Example 1, Figure 1 , Figure 4 and Figure 5 As shown, a clamping mechanism 10 is also included, and the clamping mechanism 10 includes a slide rail 101, a friction member 102, a bidirectional screw 103 and a fixed block 104. The upper right portion of the fixed plate 2 on the right side is connected to the slide rail 101, and the front and rear sides of the upper right portion of the fixed plate 2 on the right side are connected to the fixed blocks 104, and the fixed blocks 104 are both located above the slide rail 101. Bidirectional screws 103 are rotatably connected between the fixed blocks 104, and the front and rear sides of the bidirectional screw 103 are threadedly connected with friction members 102 for clamping the rotating shaft 3, and the friction members 102 are slidably connected to the slide rail 101, and the friction members 102 are respectively located on the left and right sides of the rotating shaft 3, and the friction members 102 are squeezed and fitted with the rotating shaft 3.

[0027] After the counterweight 8 contacts the bottom surface of the water area, in order to prevent the rotating shaft 3 from accidentally rotating and causing the pull rope 4 to loosen more, people can immediately turn the bidirectional screw 103 by hand after the counterweight 8 contacts the bottom surface of the water area, so that the bidirectional screw 103 drives the friction member 102 to move toward the side in the direction of approaching each other, so that the friction member 102 can clamp the right part of the rotating shaft 3, thereby preventing the rotating shaft 3 from accidentally rotating. When the rotating shaft 3 needs to be rotated in the opposite direction, the bidirectional screw 103 is turned in the opposite direction by hand, so that the bidirectional screw 103 drives the friction member 102 to move away from each other, so that the rotating shaft 3 is loosened and can rotate normally.

[0028] like Figure 1 and Figure 6 As shown, it also includes a reminder mechanism 11, which includes a button 111, a buoy 112 and a warning light 113. The lower part of the counterweight 8 is connected with the button 111, and the front upper part of the pull rope 4 is slidably connected with the buoy 112. The buoy 112 is located between the rotating part 6 and the counterweight 8. The upper part of the buoy 112 is evenly connected with three warning lights 113 along the circumferential direction. The warning lights 113 are all electrically connected to the button 111, and the button 111 contacts the bottom surface of the water area, so that the button 111 turns on the warning light 113, and the warning light 113 lights up to remind people that the counterweight 8 has contacted the bottom surface of the water area.

[0029] When the counterweight 8 drives the front lower part of the pull rope 4 to move downward, the buoy 112 will also move downward. When the buoy 112 contacts the water surface, because the buoyancy of the water is greater than the force of the pull rope 4 on the buoy 112, the buoy 112 will float on the water surface, and the pull rope 4 will be pulled downward continuously, so the distance between the counterweight 8 and the buoy 112 will gradually increase. After the counterweight 8 contacts the bottom surface of the water area, the button 111 will also contact the bottom surface of the water area, so the button 111 will be triggered, and the water will flow out of the water. The warning light 113 can be turned on by pressing the button 111. The warning light 113 will light up for ten seconds and then turn off automatically. When people see the warning light 113 light up, they can immediately know that the counterweight 8 has touched the bottom of the water area, so they can immediately stop rotating the shaft 3. This makes it convenient for people to observe the water level. When the pull rope 4 drives the counterweight 8 to move upward, when the distance between the buoy 112 and the counterweight 8 is restored, the buoy 112 will move upward and reset under the drive of the pull rope 4.

[0030] like Figure 1 As shown, wheels 12 are also included, and the front and rear sides of the base 1 are both symmetrically rotatably connected with wheels 12 for moving the base 1 with little effort.

[0031] When the base 1 is moved, the base 1 can be driven to move by the rotation of the wheels 12, thereby reducing the physical effort expended by people, thereby achieving the purpose of labor saving.

[0032] like Figure 1 As shown, a lighting lamp 13 is also included. Both left and right sides of the front of the base 1 are connected with lighting lamps 13 for supplementary lighting.

[0033] To observe the scale lines on the pull rope 4 at night or in an environment with insufficient light intensity, the lighting lamp 13 can be turned on to provide additional light, thereby making it easier for people to observe the water level.

[0034] The technical principles of the embodiments of the present utility model are described above in combination with specific embodiments. These descriptions are only for explaining the principles of the embodiments of the present utility model, and cannot be interpreted in any way as limiting the protection scope of the embodiments of the present utility model. Based on the explanations here, technicians in this field can think of other specific implementation methods of the embodiments of the present utility model without creative work, and these methods will fall within the protection scope of the embodiments of the present utility model.
