Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering, and in particular to a water quality sampling device for water conservancy engineering. Background Technology

[0002] Water conservancy projects are mainly constructed to control and regulate surface water and groundwater in nature to achieve the purpose of eliminating harm and promoting benefits. Only by constructing water conservancy projects can we control water flow, prevent floods, and rationally regulate and allocate water resources to meet the water needs of people's lives and production. In water conservancy projects, trenches are often dug to lay water pipelines, which is a common water conservancy construction process. In the field of water conservancy projects, water quality monitoring is a crucial task. Accurately grasping the water quality status is of great significance for the rational management of water resources, environmental protection, and the safe and stable operation of water conservancy projects.

[0003] Water quality sampling mainly involves two methods: manual sampling and mechanical sampling. Manual sampling is not only labor-intensive and inefficient, but also makes it difficult to guarantee sampling accuracy. Mechanical sampling devices improve sampling efficiency to some extent, but conventional sampling devices are difficult to precisely control the sampling depth, so the collected water samples cannot accurately represent the water quality at a specific depth. Moreover, most sampling devices cannot collect water samples from multiple depths at the same time, resulting in long sampling times and low efficiency. To address these issues, we propose a water quality sampling device for water conservancy projects. Utility Model Content

[0004] The purpose of this invention is to provide a water quality sampling device for water conservancy projects to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A water quality sampling device for water conservancy projects includes a mounting frame. A wire-laying box is fixedly connected to the upper surface of the mounting frame. A limiting groove is formed on the right side of the wire-laying box. A guide block is slidably connected to the inner wall of the limiting groove. A lifting line is fixedly connected to the output end of the wire-laying box. A wire-laying counter is fixedly embedded in the upper surface of the mounting frame. The end of the lifting line away from the wire-laying box passes through the guide block and the wire-laying counter in sequence and extends to the bottom of the wire-laying counter. A protective sleeve is fixedly connected to the bottom surface of the lifting line. A water inlet groove is formed on the outer surface of the protective sleeve. A filter screen is fixedly connected to the inner wall of the water inlet groove. A sampling container is provided inside the protective sleeve. A connecting thread is formed on the outer surface of the sampling container. The protective sleeve is threadedly connected to the sampling container through the connecting thread. A set of graded sampling ports and a set of graded drainage ports are formed on the outer surface of the sampling container. A sealing plug is snapped into the inner wall of each graded drainage port.

[0007] In a further embodiment, a mounting base is fixedly connected to the bottom surface of the mounting bracket, and mounting blocks are fixedly connected to the left and right sides of the mounting base, with a fixing pin threaded onto the inner wall of each mounting block.

[0008] In a further embodiment, a power supply base is fixedly connected to the upper surface of the cable feeding box, and a running indicator light is fixedly connected to the upper surface of the power supply base.

[0009] In a further embodiment, a control switch is fixedly embedded on the upper surface of the cable delivery box, and an integrated panel is fixedly connected to the upper surface of the power supply base.

[0010] In a further embodiment, a connecting block is fixedly connected to the outer surface of the protective sleeve, a connecting line is fixedly connected to the bottom surface of the connecting block, and a counterweight is fixedly connected to the bottom surface of the connecting line.

[0011] In a further embodiment, the bottom surface of the sampling container is provided with a rotating protrusion, and the outer surface of the rotating protrusion is provided with anti-slip texture.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This device records the length of the lifting line using a line counter, thereby calculating the descent depth of the sampling container. This allows for precise control of the sampling depth, avoiding sampling errors caused by inaccurate depth estimation. It ensures that the collected water samples accurately represent the water quality at a specific depth. The lifting line slowly lowers the protective sleeve and the internal sampling container. Once the sampling container reaches the predetermined depth, water enters the protective sleeve through the inlet trough and filter, and then enters the sampling container through the tiered sampling ports. The sampling container samples at different depths, with each sample entering the container through a different tiered sampling port. This ensures that water samples from each depth are collected independently without interference, enabling more accurate analysis of the water quality characteristics at different depths. This provides more detailed and precise data for water quality monitoring in water conservancy projects. Attached Figure Description

A rotating protrusion 21 is provided on the bottom surface of the sampling container 18. The outer surface of the rotating protrusion 21 is provided with anti-slip texture. The rotating protrusion 21 makes it easy for staff to separate the sampling container 18 from the protective sleeve 12.

[0025] The working principle of this utility model is as follows:

[0026] In use, first install the device at the location of use and connect it to the power supply. Then press the control switch 8, operate the integrated panel 5 to start the wire release box 4 to lower the lifting wire 11. The lifting wire 11 slides in the limit groove 6 through the guide block 7, which serves as a guide. The wire release counter 24 can record the length of the lifting wire 11 released, thereby calculating the lowering depth of the sampling container 18. The lifting wire 11 drives the protective sleeve 12 and the internal sampling container 18 to slowly lower. When the sampling container 18 reaches the predetermined depth, water flows through the water inlet groove 13 on the protective sleeve 12 and... The filter screen 17 enters the protective sleeve 12 and then enters the sampling container 18 through the graded sampling port 20 on the sampling container 18. The sampling container 18 samples at different depths, and the water sample at each depth enters the sampling container 18 through a different graded sampling port 20 to achieve graded sampling. After sampling is completed, the pay-off box 4 is started to rotate in reverse to start the recovery of the lifting line 11, which slowly lifts the protective sleeve 12 and the sampling container 18 to the water surface. After the sampling container 18 is recovered, the sealing plug 23 on the graded drain port 22 is opened to discharge the water sample for subsequent water quality analysis.
