Embodiment Construction

[0013] The specific implementation manner of the invention will be further described below in conjunction with the accompanying drawings.

[0014] After the device reaches the designated water area, such as figure 1 The sampling heater 1 is placed in a designated water area by the expansion and contraction height of the sampling expansion rod 10 . Lifting the gate switch handle 9 lifts the water inlet and outlet gate 7 and slides the gate groove 8 along the gate, so that the external water sample enters. Put down the gate switch handle 9 and close the water inlet and outlet gate 7 after the water inlet is completed, and the external water sample stops entering, and the sampling is completed. The start-up control shows that the single-chip microcomputer 11 uses the heating resistance wire 2 to heat the internal water sample. At this time, the sampling heater heat insulating layer 5 between the sampling heater inner wall 4 and the sampling heater outer wall 6 plays a role of h...

Abstract

The invention relates to a device for measuring suspended load sand content through a specific heat capacity method in a non-contact mode, and belongs to the technical field of suspended load sand content measurement. The device comprises a sampling heater, a sampling telescopic rod, a display-control single chip microcomputer, and a device connecting circuit. The sampling telescopic rod is used for placing the sampling heater to a water area to be measured, and a gate switch handle is used for opening a water-passing gate for sampling. The display-control single chip microcomputer is started to heat internal water samples through resistive heaters. A temperature sensor is used for measuring temperature, and the display-control single chip microcomputer is used for automatically measuring time. The display-control single chip microcomputer is used for automatically obtaining liquid specific heat of combustion according to rising temperature, heating time, electric heating calculated values and other parameters, and outputting sand content values through the relation of the input specific heat of combustion and sand content. The device is a reliable measuring instrument for measuring sand content of water areas with high sand content, measuring instantaneity is good, measuring work is greatly simplified, and the device can be used for monitoring water sand conditions in real time at flood seasons.

Description

technical field [0001] The present invention relates to the technical field of measuring suspended sediment content, specifically, it is a device for non-contact measurement of suspended sediment content by specific heat capacity method, which is suitable for suspended sediment in rivers, ports, and under dams. Measuring instrument for content measurement. Background technique [0002] The sediment content of water body is an important influencing factor in the study of soil erosion, soil and water conservation, channel dredging, and river course evolution analysis, so the determination of sediment content is particularly important. At present, the methods of measuring sediment concentration are mainly divided into two categories: instrumental method and physical method. The instrumental method is divided into the drying method and the specific gravity method. Although the accuracy is high, it is time-consuming and laborious, and the real-time performance is not good. The ...
