detailed description

Next, with reference to the accompanying drawings, through the description of the embodiments, the specific implementation of the present utility model will be further described in detail, the purpose is to help those skilled in the art to have a more complete, accurate and in-depth understanding of the concept and technical solutions of the present utility model , and contribute to its implementation.

As shown in Figure 1, the utility model provides a field rainwater sampler, including a box body 9, a rainwater sampling pool 6 arranged in the box body 9 and used to collect runoff rainwater, and a rainwater sampling pool 6 arranged in the rainwater sampling pool 6 The sampling bottle 8 and the rain bucket 3 arranged above the rainwater sampling bottle 8 . The water outlet of the rain bucket 3 is connected with the water inlet of the rainwater sampling bottle 8 through the guide tube 4, and the rainwater that does not fall to the ground flows into the rainwater sampling bottle 8 through the rain bucket 3 and the guide tube 4 during rainfall. A water inlet for runoff rainwater to flow in is provided on the side wall of the box body 9 , and the runoff rainwater entering the box body 9 from the water inlet will eventually flow into the rainwater sampling tank 6 .

Specifically, as shown in Figure 1, the box body 9 is a structure with an opening at the top, a closed bottom and a hollow interior, and the inner bottom of the box body 9 has a slot for accommodating the rainwater sampling pool 6, and the rainwater sampling pool 6 is embedded in the slot After installation, the rainwater sampling tank 6 can be taken out from the casing 9. The rainwater sampling tank 6 is also a structure with an opening at the top, a closed bottom and a hollow interior. The rainwater sampling bottle 8 is placed in the rainwater sampling tank 6 and can be taken out from the rainwater sampling tank 6 .

As shown in Figure 1, preferably, the size of the rainwater sampling pool 6 is slightly smaller than the size of the box body 9, after the rainwater sampling pool 6 is placed in the slot in the box body 9, the outer wall surface of the rainwater sampling pool 6 and the box body There is a gap between the inner wall surfaces of the body 9, and the gap forms a water tank 10 for receiving runoff rainwater. The water storage tank 10 is an annular groove positioned at the outside of the rainwater sampling tank 6, so that the runoff rainwater on the ground first flows into the water storage tank 10 through the water inlet on the side wall of the casing 9, rather than directly flowing into the rainwater sampling tank 6. The rainwater first fills up the water tank 10, and then the runoff rainwater overflows from the upper part of the rainwater sampling tank 6 into the rainwater sampling tank 6, so that the runoff rainwater can be preliminarily settled before entering the rainwater sampling tank 6, reducing the rainwater sampling tank 6. The content of sediment in the water samples.

As shown in Figure 1, preferably, the rain bucket 3 is arranged at the top opening of the box body 9, and the top water inlet of the rain bucket 3 is also provided with an upper filter screen 2 for filtering rainwater. The filter screen 2 is a mesh structure approximately equal in size to the top water inlet of the rain bucket 3 . The upper filter screen 2 has a filtering function to prevent large particles from entering the rainwater sampler during rainfall, blocking the diversion pipe 4 and affecting the quality of the sampled water.

As shown in Figure 1, the top surface of rainwater sampling pond 6 is provided with the water inlet that allows the runoff rainwater in the water storage tank 10 to enter, and the top surface of rainwater sampling pond 6 is flush with the water inlet established on the side wall of casing 9 or Located below the water inlet, that is, the top surface of the rainwater sampling tank 6 cannot be higher than the height of the lowest point of the water inlet provided on the side wall of the box body 9, so that it can ensure that the runoff rainwater in the water storage tank 10 can enter the rainwater In the sampling pool 6.

As shown in Figure 1, as preferably, the water inlet that is set on the side wall of box body 9 is provided with the side filter screen 5 that is used to filter the runoff rainwater, and the side filter screen 5 can prevent the runoff rainwater from carrying large particulate matter to enter The sampler affects the quality of the sampled water. The water inlets set on the side wall of the box body 9 are arranged on the side wall along the circumferential direction, and all the water inlets are at the same height, so as to ensure that the runoff rainwater can quickly enter the water storage tank 10 and the rainwater sampling tank 6 .

As shown in Figure 1, preferably, a cover plate 1 is also provided on the top of the box body 9, and the rain bucket 3 and the upper filter screen 2 are located under the cover plate 1, and the cover plate 1 is used to close the box body 9. Open top. When in non-rainfall period, the cover plate 1 is covered on the casing 9 to prevent sundries from falling into the sampler and affecting the water quality of the water sample when it is not raining. At the same time, the cover plate 1 can also protect the sampler, and a warning slogan can be set outside the cover plate 1 . Before the rain falls, the cover plate 1 can be opened to perform rainwater sampling when it rains.

When using the sampler with the above structure to sample rainwater, the sampler can be installed at the sampling point after the sampling point is determined. As shown in Fig. 1, the sampler is installed semi-underground, and the position below the side filter screen 5 of the box body 9 is inserted into the pit provided at the sampling point, and the sampler is firm after installation. At this time, the rain bucket 3 is higher than the ground, which can reduce the impact of surface runoff rainwater splashing into the rain bucket 3 and the water quality of the water sample in the rainwater sampling bottle 8 during rainfall. The bottom of the side filter screen 5 is flat with the ground surface, so that the surface runoff rainwater flows into the sampler conveniently. After the runoff rainwater enters the sampler, it does not directly flow into the rainwater sampling tank 6, but first enters the water tank 10 and fills up the water tank 10, and then enters the rainwater sampling tank 6, so that the runoff rainwater enters the rainwater sampling tank 6 before Preliminary precipitation can be carried out to reduce the content of water sample sediment in the sampling pool. The cover plate 1 can be opened before the rain to take samples. After the rainfall ends, the staff can remove the rain bucket 3, take out the rainwater sampling bottle 8 and the rainwater sampling pool 6, and obtain rainwater samples and runoff rainwater samples. Put into new rainwater sampling pond 6 and rainwater sampling bottle 8 after sampler is cleaned up then, cover cover plate 1 for later use.

The utility model has been exemplarily described above in conjunction with the accompanying drawings. Apparently, the specific implementation of the present invention is not limited by the above methods. As long as the various insubstantial improvements made by adopting the method concept and technical solution of the present utility model; within the scope of protection.
