Embodiment

[0021] Embodiment: a kind of suspended sediment automatic sampling device, such as figure 1 , 2 shown. The device includes a sampling chamber 1, an electrical appliance compartment 18 is arranged on the upper part of the sampling chamber, and a ventilation opening 17 is arranged on the middle part of the top surface of the sampling chamber. The center of the bottom surface of the sampling chamber is provided with a downwardly extending cylindrical sampling shield 2 , hollow convection holes are arranged on the side wall of the sampling shield, and the bottom surface of the sampling shield is closed with a steel wire mesh. The upper end of the sampling guard 2 is higher than the highest water level of the river over the years, and the lower end of the sampling guard is lower than the lowest water level of the river over the years. The outer side of the sampling guard 2 is provided with a water level telemetry sensor 15 on the bottom surface of the sampling chamber wall, and th...

Abstract

The invention relates to a suspended sediment load automatic sampling device, which solves the problem that the suspended sediment load automatic sampling in the prior art is generally completed manually, the workload is large, and the sampling standard is affected by manual works. The suspended sediment load automatic sampling device includes a sampling chamber; the center of the bottom of the sampling chamber is provided with a cylindrical sampling shield extended downward; the side wall of the sampling shield is provided with a hollow convection hole; a lifting device is arranged verticallybetween the top of the sampling chamber and the lower end of the sampling shield; one side of the lifting device is hingedly provided with a sampling cylinder which can be turned over outward; a circular rail is arranged in the sampling chamber surrounding the sampling shield; sampling bottles are evenly arranged on the circular track; a funnel fixed to the inner wall of the sampling chamber is arranged at a position corresponding to the sampling cylinder above the circular rail; and the bottle mouth is aligned with the lower end of the funnel when the sample bottle is rotated to the positionunder the funnel. According to the invention, the results of multiple sampling are filled into the sampling bottle separately, and the weighing of the muddy water sample is directly completed after the sampling is completed; therefore, the influence of water evaporation on the measurement accuracy is avoided.

Description

technical field [0001] The invention relates to a hydrological information collection device, in particular to an automatic sampling device for suspended sediment. Background technique [0002] The hydrological department needs to monitor the hydrological information of the river all year round, provide hydrological data for various construction plans of the country, and play an important role in the development planning around the river. Suspended sediment, also known as suspended sediment, refers to the sediment suspended in water and moving with the current due to the turbulence of water flow. Suspended sediment index is an important index required for the construction of water conservancy and hydropower projects, which will affect reservoir siltation, channel evolution, siltation of diversion head and canal system, etc. The sediment concentration monitoring of suspended sediment needs to firstly sample the river water body, and then measure the sediment concentration in...
