To learn the operating state of a pipe network, pipe flow monitoring has been developed as a means, however, many practical problems have been found in the process of pipe flow monitoring and are in need of solution. The most important problem is that the amount of solid waste in the pipeline is large, and the part of the waste mainly comprises plastic bags, kitchen waste, leaves, fibers and the like, and the waste has great adverse effect on the pipeline flow monitoring. The garbage advances along with the water flow, and the garbage is likely to cover the surface of the flowmeter probe to block the normal route of ultrasonic waves so as to influence the normal operation of the flowmeter. In this case, we need to take out the probe at the front end of the flowmeter for garbage cleaning and then put it back into the pipeline. However, the probe is difficult to be placed at the original position, such as the position of the pipeline, the direction of the probe and the like, and the original parameters are not suitable for the current state of the probe any more, so that a large measurement error is caused.
In the prior art, the grid is used for blocking the solid garbage in the water, if the grid is too large to enter the pipeline, if the grid is too small, the grid cannot block the solid garbage in the water when the water flow is large.
