Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy survey accessory devices, in particular to a water conservancy survey sampling device. Background Art

[0002] As we all know, water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. They are also called water projects. Water is an indispensable and precious resource for human production and life, but its natural state does not fully meet human needs. Only by building water conservancy projects,

[0003] In order to control the flow of water, prevent floods and waterlogging, and regulate and distribute the amount of water to meet the needs of people's lives and production for water resources. Water conservancy projects require the construction of different types of hydraulic structures such as dams, dikes, spillways, sluices, water inlets, channels, ferries, rafts, fishways, etc. to achieve their goals. In water conservancy projects, it is often necessary to sample water to detect water quality. At this time, a sampling device is needed. It is found in existing use that most of the existing sampling devices have a simple structure and can only collect water samples in the same area of ​​the water source. When collecting water samples in different areas, personnel need to take a boat to different collection areas for collection. The collection method is relatively cumbersome and has poor practicality.

[0004] Patent No. CN220525378U in the prior art discloses a novel water sampling device for water conservancy investigation, in particular, a device that can sample water at different depths by driving a traction mechanism to move through a motor without replacing the sampling device, and then controlling the sampling mechanism with an electromagnetic valve, thereby improving the working efficiency and effect of sampling at different depths, and thus enhancing the practicality of the novel water sampling device for water conservancy investigation; the device comprises a protective box, a power supply mechanism, a support rod, a telescopic cylinder, a connecting rod, a traction mechanism and a sampling mechanism, the protective box being provided with a working chamber, the power supply mechanism being arranged in the left area of ​​the working chamber of the protective box, the bottom of the support rod being connected to the left area of ​​the top of the protective box, the left end of the connecting rod being connected to the right end of the telescopic cylinder, and the sampling mechanism also comprising four groups of U-shaped plates, a first connecting block, four groups of sampling boxes, four groups of electromagnetic valves and four groups of sliding mechanisms.

[0005] However, the patents under the existing technology have the following disadvantages:

[0006] (1) This utility model water sampling device for water conservancy investigation does not have the function of throwing and ejecting the sampling bottle, resulting in that the sampling bottle can only collect water samples near the water source. When it is necessary to collect water samples at the center of the water source, it is necessary to carry this water sampling device for water conservancy investigation on a boat to the center of the water source for water sample collection. The collection method is too cumbersome and inconvenient. Utility Model Content
