Description

A sludge thickness detection device

Technical Field

The utility model relates to the field of detection devices, in particular to a sludge thickness detection device.

Background technique

Ultrasonic mud level meter is also called ultrasonic sludge interface meter. It is designed for long-term reliable operation in industrial and municipal fields. The sensor can work when immersed in water, and the height of the sludge layer is determined by ultrasonic emission and echo analysis of suspended solids in water.

In the prior art, it is necessary to detect the thickness of the silt layer in the river channel before the construction of a water conservancy project. The detection of the thickness of the silt layer requires the use of an ultrasonic mud level meter. When using an ultrasonic mud level meter to detect the silt layer in the river channel, in order to prevent the probe from shaking due to the influence of water flow and other factors when placed in the water and thus affecting the detection result, the probe needs to be installed on a pipe. During the detection, the detection personnel hold the pipe and place the probe at the bottom into the river water to detect the thickness of the silt layer. However, when detecting the thickness of the silt layer in the above manner, since the detection personnel need to hold the pipe for a long time during the detection process, the detection personnel's arms are prone to fatigue after a long time, which may cause the detection personnel to be unable to hold the pipe steadily, causing the probe to move, and affecting the detection result, and requiring re-detection, which causes inconvenience to the detection operation of the silt layer thickness.

A rotating rod 10 is fixedly installed at the upper and lower ends of the screw rod 9, and the rotating rod 10 is movably installed in the rotating hole 8. The drive motor 11 is fixedly installed on the top surface of the support plate 1, and the output end of the drive motor 11 is fixedly installed together with the rotating rod 10 at the upper end. The rear ends of the two side walls of the movable plate 12 are respectively fixedly installed with sliding blocks 14, and the sliding blocks 14 are movably installed in the vertical sliding holes. In the opening 7, a threaded hole 13 is provided at the rear end of the top surface of the movable plate 12, and the movable plate 12 is threadedly connected to the screw rod 9 through the threaded hole 13.

The purpose of the mobile power supply 4 is to control the power supply of the driving motor 11 and the ultrasonic mud level meter 18. When detecting the thickness of the silt layer in the river channel, the universal wheel 3 installed on the bottom surface of the T-shaped plate 2 on both sides of the bottom surface of the support plate 1 is used to move the entire device to the river channel. The universal wheel 3 is a common universal wheel 3 with self-locking function. The self-locking of the universal wheel 3 prevents the entire device from moving, and the probe 19 at the bottom of the casing 16 is placed above the river water area. Then, the driving motor 11 installed on the top surface of the support plate 1 is turned on. The driving motor 11 will drive the output end to rotate and drive the rotating rod 10 to rotate in the rotating hole 8 opened on the top and bottom surfaces of the support plate 1 through the output end.

Finally, the thickness of the silt layer in the river channel is detected by the probe 19, and the detection result is transmitted to the ultrasonic mud level meter 18 by the connecting line 20 for display to the detection personnel, thereby completing the detection operation of the thickness of the silt layer in the river channel. During the detection, there is no need for the detection personnel to hold the casing 16 for a long time to ensure the stability of the probe 19 during the detection process. The detection operation not only saves time and effort, but also effectively prevents the displacement of the probe 19 during the detection, thereby ensuring the accuracy of the detection result and achieving the purpose of facilitating the detection of the thickness of the silt layer in the river channel.

The prior art principle of the ultrasonic mud level meter 18 is: using ultrasonic echo technology to measure the water surface, the sensor emits ultrasonic waves that are reflected when encountering the mud layer, and the time between the transmitted wave and the reflected wave is measured to obtain the distance L1 from the sensor to the mud layer; the distance from the sensor to the bottom of the river channel is L set by the user; in this way, the thickness of the mud layer d=L-L1 can be obtained.
