Description

Technical Field

[0001] This application relates to the field of environmental monitoring or environmental protection equipment, and specifically relates to a river sewage sampling device. Background Art

[0002] After it is found that sewage has been discharged into the river, it is necessary to quickly evaluate the quantity and composition of pollutants, including whether they have penetrated into deeper water bodies. However, the river water is flowing, and the pollutants are also gradually spreading downstream and deeper. It is necessary to sample water samples at different depths at the same time in order to accurately evaluate. The sampling devices in the prior art cannot sample at different depths at the same time, or have a complex structure. There is an urgent need to design a new type of river sewage sampling device. Summary of the Utility Model

[0025] The following further describes the present utility model in conjunction with embodiments.

[0026] As Figure 1 shown, a river sewage sampling device according to this application is characterized in that: it includes a main rod 1 and a sub - rod 2, and at least two sampling devices are connected between the main rod 1 and the sub - rod 2; the sampling device includes a connecting piece 3, and both ends of the connecting piece are rotatably connected to the main rod and the sub - rod respectively; a sampling bottle 4 is arranged on the connecting piece, and when the main rod and the sub - rod are in the first close - fitting position, the bottle mouth is in the vertically downward direction.

[0027] As Figure 7 , it shows the movement process of the device of this application. First, the main rod and the sub - rod are close - fitting, and the bottle mouth on the connecting piece that rotates and connects them is exactly downward; since multiple sampling devices connect the two rods, a parallelogram mechanism can be formed, and the two rods can be pulled apart in parallel and be close - fitting at another position ( Figure 7 right - most figure), and at this time, the bottle mouth also rotates by a large angle and is close to the bottle mouth facing upward.

[0028] Furthermore, there are three sampling devices.

[0029] Furthermore, the sampling bottle is arranged on the connecting piece through a hoop.

[0030] Furthermore, the diameter of the bottle mouth of the sampling bottle is smaller than the bottle body.

[0031] Furthermore, a handle is also arranged on the main rod, and a level is arranged on the handle.

[0032] Furthermore, a scale is also arranged on the main rod.

[0033] When in use, first, as shown Figure 7 at the leftmost side, press the two rods closely together, then observe the level gauge and vertically insert the two rods into the river water. At this time, the depth of each sampling device can be understood through the scale. Since the mouth of the sampling bottle faces downward, water will not enter at this time. Then, as shown Figure 7 in the middle figure, pull the two rods apart until, as shown Figure 7 at the right side, press them closely together again. At this time, the mouth of the sampling bottle will change from the original vertical downward to generally upward, and water will start to enter. Then take out this device, and the water samples in each bottle are the water samples at different depths at the same moment.

[0034] The above has described a detailed description of an embodiment of the present utility model. However, the content described above is only a preferred embodiment of the present utility model and cannot be considered as used to limit the scope of implementation of the present utility model. All equivalent changes and improvements made according to the scope of the application of the present utility model should still fall within the scope covered by the patent of the present utility model.
