DETAILED DESCRIPTION
[0019] The technical solutions in the embodiments of the present application will be clearly and completely described with reference to the drawings in the embodiments of the present application.
[0020] Embodiment 1: Reference Figures 1-5 A water level pole comprises a scale pole 100 and a mounting box 1, both of which are fixedly installed on the surface of a dike wall by bolts, the surface of the dike wall is vertical, and the surface of the scale pole 100 is marked with scale lines for indicating the water level. The scale pole 100 is located on one side of the mounting box 1, and a guide rod 2 is fixedly installed inside the mounting box 1. The scale pole 100, the mounting box 1 and the guide rod 2 are arranged in parallel along the length direction and are all vertically arranged. A sleeve rod 3 is slidably sleeved outside the guide rod 2, an inner ring 31 is fixedly installed on the inner side surface of the sleeve rod 3, and the surface of the inner ring 31 in contact with the guide rod 2 is in the shape of a circular arc, so as to reduce the friction between the sleeve rod 3 and the guide rod 2, make the sleeve rod 3 slide up and down more smoothly, and ensure that the sleeve rod 3 will not be skewed. A float 4 is fixedly installed on the outer side of the sleeve rod 3, the float 4 can float on the water surface, and the float 4 will move up and down along with the rise and fall of the water surface, and the float 4 will drive the sleeve rod 3 to move up and down along the guide rod 2 at the same time.
[0021] A connecting rod 5 is fixedly installed on one side of the float 4, a sliding groove 14 is formed on the surface of the mounting box 1 close to the scale pole 100, the end of the connecting rod 5 penetrates through the sliding groove 14 and extends to the outer side of the mounting box 1, a indicating plate 6 is fixedly installed on the end of the connecting rod 5, the upper end of the indicating plate 6 is located on one side of the scale pole 100, the scale on the scale pole 100 pointed by the upper end of the indicating plate 6 is the water level height, a camera 16 is fixedly installed on the upper surface of the connecting rod 5, the camera 16 points to the scale plate 100 and can shoot the scale pointed by the indicating plate 6, the camera 16 is connected with a control mechanism and a power supply through wires, and is connected with a computer or a mobile phone of a detection station through a wireless network, so that the water level can be viewed by the detection station through the computer or the mobile phone and the like. In addition, the camera 16 is a waterproof camera, which can prevent water from entering when being splashed by waves and prolong the service life.
[0022] When the water level changes, the height of the float 4 will change along with the change of the water level, the movement of the float 4 will drive the sleeve rod 3 and the connecting rod 5 to move up and down, the sleeve rod 3 can ensure that the float 4 remains stable, the movement of the connecting rod 5 can drive the camera 16 and the indicating plate 6 to move up and down, the scale pointed by the indicating plate 6 will change along with the rise of the water level, the scale on the scale pole 100 can be shot by the camera 16 and then sent to the detection station, so that the staff need not go to the site to observe the water level, and need not risk to observe the scale pole 100 at the edge of the dike.
[0023] Working principle: in the use process of the water level pole, the float 4 floats on the water surface, and the scale pointed by the indicating plate 6 is the height of the water level. When the water level rises or falls, the float 4 will move up or down, and the sleeve rod 3 can keep the balance of the float 4. The inner ring 3 can reduce the friction between the sleeve rod 3 and the guide rod 2, so as to avoid the sleeve rod 3 being blocked on the guide rod 2 due to friction. The movement of the float 4 drives the connecting rod 5 to move up and down, and the connecting rod 5 drives the camera 16 and the indicating plate 6 to move at the same time. The scale pointed by the indicating plate 6 is the height of the water level after the change, and the staff can observe the water level without going to the scene, which is safer and more convenient than observing the scale rod 100 at the edge of the dam. If the water level rises greatly and reaches the warning water level, the staff can set an alarm around the dam in advance, and when the water level rises to the dangerous water level, the alarm can be remotely controlled to issue an alarm, which can provide warning to pedestrians and drivers nearby.
[0024] The part of the scale rod 100 below the water surface is soaked in water for a long time, and the surface of the scale rod 100 is easy to stick with sundries or grow moss, which will affect the clarity of the scale. The indicating plate 6 is internally provided with a containing cavity 11, and a turbine 13 is rotatably installed in the containing cavity 11. One end of the turbine 13 extends to the outside of the indicating plate 6 and is fixedly installed with a fixed plate 7. The turbine 13 and the fixed plate 7 are coaxially arranged, and the fixed plate 7 is fixedly installed with a cleaning brush 8 on the surface. The rotation of the turbine 13 can drive the rotation of the fixed plate 7, so as to drive the rotation of the cleaning brush 8. The cleaning brush 8 can clean the surface of the scale rod 100. The indicating plate 6 is also fixedly installed with a pump body 12. The end of the pump body 12 is connected with the inside of the containing cavity 11, and a water outlet hole 10 is formed in one side of the bottom of the containing cavity 11. When the pump body 12 is started, the pump body 12 will pump water in the water into the containing cavity 11. The water entering the inside of the containing cavity 11 will directly flow to the turbine 13, so as to drive the turbine 13 to rotate. The rotation of the turbine 13 can drive the rotation of the fixed plate 7, and the rotation of the fixed plate 7 can clean the surface of the scale rod 100 through the cleaning brush 8. When the pump body 12 is started, the valve body in the water outlet hole 10 is also opened, and the water at the bottom of the containing cavity 11 will be discharged outward through the water outlet hole 10.
[0025] The fixed plate 7 is fixedly installed with an annular net plate 9, and the water outlet hole 10 is located on one side of the net plate 9. Because the water flow entering the containing cavity 11 has a certain impact speed when the pump body 12 works, the water discharged from the water outlet hole 10 will flow to the cleaning brush 8 through the net plate 9, so as to flush out the sundries remaining in the cleaning brush 8.
[0026] The pump body 12 and the valve body inside the water outlet hole 12 are connected with the external control mechanism and the power supply as the camera piece 16, and the detection station can periodically control the power supply of the pump body 12 and the valve body to be connected, the pump body 12 will flush the water in the water into the containing cavity 11, and the water will drive the turbine 13 to rotate under the impact, the rotation of the turbine 13 can drive the fixed plate 7 and the cleaning brush 8 to rotate, the cleaning brush 8 can clean the surface of the scale rod 100, and the height of the water surface will be up and down with the impact of the wave, the float 4 will also fluctuate up and down, so as to drive the indicating plate 6 to fluctuate up and down, the indicating plate 6 fluctuates up and down, which drives the cleaning brush 8 to move up and down, and the cleaning brush 8 can clean the surface of the scale rod 100 in a larger range, so as to ensure the clarity of the scale on the surface of the scale rod 100.
[0027] In example 1, the chute 14 is exposed to water, although the width of the chute 14 is narrow, and no large impurities can enter, but if small leaves or small fish and shrimps in the water enter the installation box 1, it may affect the normal movement of the float 4, thereby affecting the normal detection of the water level, therefore, the present example is proposed. Figures 1-2 and Figure 4 As another preferred embodiment of the utility model, on the basis of example 1, the two opposite vertical inner wall surfaces of the chute 14 are fixedly installed with brush resistance 15, the brush resistance 15 is bristle, and the bristle is arranged on the two sides of the chute 14, and the connecting rod 5 can pass through the gap between the two brush resistances 15, when the connecting rod 5 passes, the brush resistance 15 will deform but will not affect the movement of the connecting rod 5. The brush resistance 15 can block small impurities and small fish and shrimps, and can prevent impurities from being blocked in the installation box 1 to affect the normal movement of the float 4.
[0028] The above is only a preferred specific embodiment of the utility model, but the protection scope of the utility model is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the utility model concept of the utility model within the technical range disclosed by the utility model, which should be covered in the protection scope of the utility model.
