Problems solved by technology
[0004] The purpose of the present invention is to address the deficiencies of the existing methods for measuring sedimentation in drainage pipes, and propose a pressure sensor thickness measuring device for sedimentation in drainage pipes. The problem of large measurement errors caused by this method also solves the problem of inaccurate readings caused by determining the mud surface through sudden changes in pressure, thereby improving the measurement accuracy

Embodiment 1
[0017] Embodiment 1: as figure 1 - figure 2 As shown, the mud measuring device is installed on a fixed or mobile device, the diameter of the pipeline is measured by the infrared range finder, the distance in contact with the mud is measured by the pressure sensor, and the thickness of the mud is automatically calculated by the software. The waterproof level of the mud measuring device reaches Ip68;
[0018] The infrared range finder 14 is fixed on the sensor seat 1 by the first cross screw (M3X6) 15, and the sensor seat 1 is fixed on the upper cover by the first screw (M3X8) 2, the compression glass sheet 13 and the seal (32.5) 12 26 on. The servo motor 18 is fastened on the machine base 28 through the first screw (M3X8) 2, the screw rod 11 is installed on the bearing seat 5 through the angular contact bearing (S708) 6 at one end, and the other end is installed on the lower cover 29, so that the screw rod 11 is fixed It cannot move axially in series and can realize rotation...

The invention discloses a pressure sensor thickness measuring apparatus used for drainage pipeline settled sludge. The apparatus is composed of an infrared distance meter, a pressure sensor, a pressure measuring head connecting piece, a direct current motor, an encoder, a pressure rod, a control panel, a sealing assembly, a ball screw, a screw nut, a synchronous belt, a linear guide rod and a synchronous wheel. The apparatus is mounted on an inherent mobile device, a pipeline is measured through the infrared distance meter, and then the diameter of the pipeline and the specific position of a sludge measuring device are worked out. A pressure threshold of the sludge is preset, the height of the sludge surface is determined when the pressure of the pressure sensor mounted on the screw nut reaches the threshold, and the actual thickness of the sludge is calculated through software.
Description
technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a pressure sensor thickness measuring device for sedimentation silt in drainage pipes, which is suitable for measuring the thickness of sedimentation silt in rainwater pipes, sewage pipes and confluence pipes in urban drainage systems. Background technique [0002] Urban drainage pipes are an important infrastructure for urban flood control and drainage, sewage collection and transportation. So far, Shanghai has built more than 10,000 kilometers of drainage pipelines, but at the same time, it is also facing the problem of a large amount of silt deposits in the pipelines. Water bodies, resulting in water pollution. At the same time, it also brings a lot of workload to the clear maintenance of the drainage pipeline. Therefore, it is of great significance for the safety of urban flood control and the efficient maintenance of drainage pipes to carry out...
