Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring, and more specifically, to a disposable water sample collection device for environmental monitoring. Background Technology

[0002] To understand the state of environmental quality, prevent and control pollution, assess environmental risks, promote green development, and raise public awareness of environmental protection, environmental monitoring is necessary. Environmental monitoring refers to the systematic observation, measurement, and analysis of physical, chemical, and biological factors in the environment in order to understand the environmental status and predict future trends. Environmental monitoring involves the regular sampling and analysis of environmental elements such as the atmosphere, water bodies, and soil.

[0003] Water bodies originate from water bodies, including rivers, lakes, and the sea. When collecting environmental water samples from different water bodies, the sampling points at the same cross-section sampling vertical line are different. For example, for river sampling, for water depths of 0.5 to 5 meters (inclusive), one sampling point is set in the upper layer 0.5 meters below the water surface; for water depths of 5 to 10 meters, two sampling points are set in the upper layer and the lower layer 0.5 meters above the riverbed; for water depths greater than 10 meters, three sampling points are set in the upper and lower layers and the middle layer at half the water depth.

[0004] The current sampling method for the vertical line of the cross section is segmented sampling, that is, sampling at one sampling point and then sampling at the next sampling point. For cases that require sampling at multiple points, the sampling is time-consuming. Utility Model Content

[0027] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0028] Example 1

[0029] Please refer to Figure 1 , Figure 1 This is a schematic diagram of a disposable water sampling device for environmental monitoring provided in this embodiment. Figure 2 This is a schematic diagram of a cross-sectional view of a square container. Figure 3 This is a top view diagram of a square container.

[0030] A disposable water sample collection device for environmental monitoring includes a connecting component 1, at least one sampling container 2, and a sealing plate 3. The connecting component 1 and the sealing plate 3 each pass through the sampling container 2. The connecting component 1 is located at the horizontal middle position of the sampling container 2, and the sealing plate 3 is located at the horizontal edge position of the sampling container 2.

[0031] When the insert plate 3 passes through the sampling container 2, the sampling container 2 is completely sealed. When the insert plate 3 is pulled out, one side of the sampling container 2 opens. During sampling, the disposable water sampling device for environmental monitoring is placed underwater in the water area to be sampled. Then, the insert plate 3 is pulled out, and water flows into the sampling container 2 for sampling. After sampling, the insert plate 3 is inserted again, and the sampling container 2 is sealed again. Then, the disposable water sampling device for environmental monitoring is removed, and the water is taken out from the sampling container 2 and placed into a special water sample storage device.

[0032] In one or more specific embodiments of this utility model, the sampling container 2 includes a first sampling container 21, a second sampling container 22, and a third sampling container 23, arranged sequentially from top to bottom. The first sampling container 21 and the third sampling container 23 are fixed-position samplers, while the second sampling container 22 is a movable-position sampler. The first sampling container 21 is used for sampling at a point 0.5 meters below the water surface, the second sampling container 22 is used for sampling at a point half the depth of the water, and the third sampling container 23 is used for sampling at a point 0.5 meters above the riverbed. The installation position of the second sampling container 22 needs to be adjusted and determined according to the water depth. This method allows for sampling of the same cross-section in a single operation.

[0033] In one or more specific embodiments of this utility model, the connecting component 1 can be a tube or a rod, and those skilled in the art can choose according to their needs. To reduce the weight of the entire sampling device, it is preferable that the connecting component 1 is a tube.

[0034] In one or more specific embodiments of this utility model, the connecting component 1 includes a retractable upper section 11, a connecting middle section 12, and a retractable lower section 13. A first sampling container 21 is located on the retractable upper section 11, a second sampling container 22 is located on the connecting middle section 12, and a third sampling container 23 is located on the retractable lower section 13. The extension and positioning of the retractable upper section 11 and the retractable lower section 13 are existing mature technologies (such as the extension and fixed position positioning method similar to a folding umbrella, and the inner tube and outer tube method, wherein the inner tube can change its total length by extending into and out of the outer tube). Those skilled in the art can choose how to achieve the extension and length positioning as needed. When on-site sampling is required, the sampler determines the number of sampling points based on the water depth of the sampling section, and then determines the required fixed lengths of the retractable upper section 11 and retractable lower section 13 based on the water depth of the sampling section. After adjusting the lengths of the retractable upper section 11 and retractable lower section 13, one sampling container 21 is used to take samples at sampling points 0.5 meters below the water surface, the second sampling container 22 is used to take samples at sampling points at 1 / 2 water depth, and the third sampling container 23 is used to take samples at sampling points 0.5 meters above the riverbed.

[0035] In one or more specific embodiments of this utility model, in order to facilitate rapid and accurate sampling, a water surface line 14 is provided on the retractable upper section 11, and the first sampling container 21 is located below the water surface line 14. During sampling, the water surface line 14 is flush with the water surface of the cross section, so that accurate and rapid sampling can be performed.

[0036] In one or more specific embodiments of this utility model, for ease of installation and disassembly, the first sampling container 21, the second sampling container 22, and the third sampling container 23 are each square containers (the side of the square container adjacent to the insert plate 3 is open). Each of the first sampling container 21, the second sampling container 22, and the third sampling container 23 is provided with a sleeve 24. One end of the sleeve 24 extends upward through the top cover of the square container, and the other end extends downward through the bottom of the square container. The upper end of the sleeve 24 is provided with an upper mounting hole 25 for connecting to the connecting component 1, and the lower end of the sleeve 24 is provided with a lower mounting hole 26 for connecting to the connecting component 1. The connecting component 1 is connected to the sleeve 24 by fasteners. During installation, the connecting component 1 is passed through the sleeve 24, and the fasteners are passed through the upper mounting hole 25 (or the lower mounting hole 26) and the corresponding mounting hole on the connecting component 1, thereby installing the sampling container on the connecting component 1. The fasteners can be, for example, screws or bolts, or other methods that can achieve fastening, which are not specifically limited here.

[0037] In one or more specific embodiments of this utility model, in order to facilitate the insertion and removal of the insert plate 3, a groove 27 is provided on the front wall and the rear wall of the square container, and the front and rear walls of the insert plate 3 can move along a groove 27.

The lower end of the connecting component 1 is fixed to the base 4, and the base 4 is located at the bottom of the water during sampling. After sampling is completed, the disposable water sampling device for environmental monitoring can be placed on the ground after leaving the water surface, and the sample liquid can be transferred from bottom to top.

[0044] To facilitate more accurate and convenient sampling, the disposable water sampling device for environmental monitoring also includes a base 5 placed on a boat. A detachable crossbar 6 is attached to the base 5, with its other end fixedly connected to the upper end of the connecting component 1. The crossbar 6 can be detachably connected to the base 5 using bolts and nuts, or other detachable connections. No particular limitation is made here. This setup makes the sampling process more convenient and labor-saving. It is very easy to operate, requiring no manual lifting and requiring minimal effort.
