Water quality sampling device for hydrology and water resource engineering

Abstract

The invention provides a water quality sampling device for hydrology and water resource engineering. The device comprises a rod body and a sampling bottle, the rear end of the rod body is provided with a wire wheel and a measuring scale wheel, the front end of the rod body is provided with a wire guide ring, an electric wire is wound on the wire wheel, scales are arranged on the electric wire, and the electric wire penetrates through the wire guide ring to be connected with the sampling bottle; a measuring scale is arranged on the measuring scale wheel and is fixedly connected with the wire guide ring; a balancing weight is arranged at the bottom of the sampling bottle, an annular electromagnet is arranged on the inner side of a bottle opening of the sampling bottle, a baffle is arranged at the end, deviating from the bottle opening, of the annular electromagnet and hinged to the annular electromagnet, the diameter of the baffle is larger than that of the bottle opening, and a blocking cover is arranged on the outer side of the bottle opening and provided with an electromagnet. One end of the electric wire is connected with a power supply, and the other end of the electric wire penetrates through the balancing weight and the bottle bottom to be connected with the electromagnet. The distance from the sampling point to the shore can be determined through the extension length of the measuring scale, and the height from the sampling point to the water surface can be determined through the extension length of the winding rope so that the sampling position is accurately positioned, and the water quality monitoring accuracy is improved.

Description

technical field [0001] The invention belongs to the field of hydrology and water resources engineering, and in particular relates to a water quality sampling device for hydrology and water resources engineering. Background technique [0002] In order to grasp the status quo of water quality and strengthen the monitoring of water environment quality, it is necessary to conduct water quality sampling on the spot in practice. At present, the commonly used sampling method is directly sampling with a sampling bottle, and sampling by boat is required for the water intake environment with large water areas. The existing sampling is relatively random, and positioning sampling cannot be achieved. Therefore, water quality monitoring is not precise. Contents of the invention [0003] The object of the present invention is to provide a water quality sampling device for hydrology and water resource engineering, so as to solve the problem that the prior art cannot locate and sample. ,...
