Problems solved by technology

[0002] Surface water needs to be sampled at different depths in hydrological surveys. Sampling is time-consuming and laborious. The existing water quality sampling racks have great limitations and cannot meet the sampling of surface water at different depths. During the sampling process, it is impossible to observe the samples collected in the sampling bottle under the turbid water source. Therefore, it is impossible to control the amount of collected sample liquid, and when sampling in layers at the same time, when the sample liquid enters the sampling bottle, the air in the sampling bottle will be discharged to generate air bubbles, making the water source turbid, and the water of different depths will be mixed. The sample liquid of the corresponding layer is polluted by the sample liquid of the adjacent layer, which seriously affects the results of hydrological survey and cannot meet the actual needs, so we invented a water quality sampling rack for hydrological survey

Abstract

A water quality sampling rack for hydrological survey, comprising a base, a floating plate is fixedly installed on the bottom side of the base, a vertical screw nut is installed on the middle bearing on the left side of the base, a screw rod is installed on the internal thread of the screw nut, and a ring gear is fixedly installed on the upper end of the outer circumference of the screw nut , the motor is fixedly installed on the left end of the top side of the base, the gear is fixedly installed on the upper end of the motor shaft, the gear meshes with the ring gear, the lower end of the screw rod is fixedly connected to the upper end of the first vertical rod, and the left end of the bottom side of the base is fixedly connected to the second vertical rod. On the upper end, several first adjustment devices are respectively movably installed on the outer periphery of the second vertical rod. Take the device out of the survey water source, and then make the motor rotate forward until the standpipes are respectively pulled out from the corresponding sampling bottles, and then the sampling bottles are respectively removed from the corresponding sampling bottle fixing devices to complete a sampling; The first adjusting device and the fixing plate are taken off from the second vertical rod, which is convenient for cleaning the rubber pad and the vertical pipe, and is convenient for the secondary use of the device.
