Description

Technical Field

[0001] The utility model belongs to the technical field of water layer sampling equipment, in particular to a surface water layer sampling device. Background Art

[0002] Surface water is an essential resource for humans, plants, animals, and ecosystems. Its water quality is directly related to human health and ecological stability. However, due to human activities, industrial pollution, and other factors, surface water has suffered varying degrees of pollution. To accurately assess the water quality of surface water, regular monitoring and sampling are necessary. Stratified sampling, as an important sampling method, can more accurately reflect the changes in water quality at different depths, providing more reliable data support for water quality monitoring.

[0003] However, the existing surface water stratification sampling device is a tubular sampling structure, which realizes water layer sampling by setting sampling ports with height differences. However, during sampling, since water samples from different water layers need to be taken, when one of the sampling ports is working, the other sampling ports need to stop working. At the same time, after the sampling is completed, excess water needs to be discharged to avoid affecting the water samples taken by other sampling ports. The water also contains some impurities (such as mud, aquatic plants, suspended matter, etc.), which can easily enter the pipeline and cause blockage during sampling, resulting in slow sampling efficiency and imperfect working performance.

[0004] To this end, those skilled in the art have proposed a surface water stratification sampling device to solve the problems raised in the background art. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a surface water stratification sampling device to solve the problems of slow sampling efficiency, imperfect working performance and the like in the prior art.

[0006] A surface water stratification sampling device includes a water pump, the bottom end of which is connected to a filtering mechanism for improving the sampling effect when sampling water layers. The filtering mechanism includes a water pump arranged at the lower end of the water pump, and the outer end of the water pump is connected to a filtering component for blocking mud and other debris in the water when pumping water.

[0007] Preferably, the filter assembly includes a filter box conductively connected to the outer end of the water suction pipe, and a fixing frame is provided on the inner side of the filter box.

[0008] Preferably, a filter net for filtering out debris such as mud and sand in the water is provided on the inner side of the fixing frame.

[0009] Preferably, the upper end of the filter box is also provided with a closing cover for facilitating the disassembly and cleaning of the filter.

[0010] Preferably, a reinforcement plate for improving working stability is fixedly connected to the upper end of the water pump, and a lifting component for controlling the water layer sampled by the water pump is connected to the upper surface of the reinforcement plate.

[0011] Preferably, the lifting assembly includes a bottom column fixedly connected to the upper surface of the reinforcement plate, the upper end of the bottom column is connected to a lifting column for controlling the height, and a reinforcement column for improving the lifting stability is provided on the outer side of the bottom column.

[0012] Preferably, the outer side of the water pump is connected to a water outlet pipe for discharging the sampled water.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The utility model greatly improves the working safety and protection effect of the water pump through the filtering mechanism. When the water pump is sampling the water layer, the filter mesh provided in the filtering mechanism can effectively filter out some mud and sand impurities in the water and block them in the filter box. The closed cover provided on the outside facilitates the cleaning of the filter mesh after sampling, reduces the occurrence of pipeline blockage, and the lifting assembly provided above the reinforcement plate also meets the sampling work of different water layers to a certain extent, thereby realizing the detection and analysis of water samples from different water layers.

[0025] The filter assembly includes a filter box 202 which is conductively connected to the outer end of the water pumping pipe 201 , and a fixing frame 203 is provided inside the filter box 202 .

[0026] A filter screen 204 is provided inside the fixing frame 203 for filtering out debris such as mud and sand in the water.

[0027] A closing cover 205 is provided at the upper end of the filter box 202 for facilitating the disassembly and cleaning of the filter screen 204 .

[0028] A reinforcing plate 206 for improving working stability is fixedly connected to the upper end of the water pump 1 , and a lifting component for controlling the water layer sampled by the water pump 1 is connected to the upper surface of the reinforcing plate 206 .

[0029] The lifting assembly includes a bottom column 207 fixedly connected to the upper surface of the reinforcement plate 206. The upper end of the bottom column 207 is connected to a lifting column 208 for controlling the height. A reinforcement support 209 is provided on the outside of the bottom column 207 for improving the lifting stability.

[0030] The outside of the water pump 1 is connected to a water outlet pipe 210 for discharging the sampled water.

[0031] The filtering mechanism 2 greatly improves the working safety and protection effect of the water pump 1. When the water pump 1 is performing water layer sampling, the filter mesh 204 provided in the filtering mechanism 2 can effectively filter out some mud and sand impurities in the water and block them in the filter box 202, and the closed cover 205 provided on the outside facilitates the cleaning of the filter mesh 204 after sampling, reducing the occurrence of pipeline blockage, and the lifting component provided above the reinforcement plate 206 also meets the sampling work of different water layers to a certain extent, thereby realizing the detection and analysis of water samples from different water layers.

[0032] The filtering mechanism 2 includes a water suction pipe 201 which is arranged at the lower end of the water pump 1. The outer end of the water suction pipe 201 is connected to a filtering component for blocking mud and other debris in the water when pumping water. The filtering component includes a filter box 202 which is connected to the outer end of the water suction pipe 201. A fixed frame 203 is provided on the inner side of the filter box 202. A filter net 204 for filtering mud and other debris in the water is provided on the inner side of the fixed frame 203.

[0033] The upper end of the filter box 202 is also provided with a closing cover 205 for facilitating the disassembly and cleaning of the filter screen 204.

[0035] As can be seen from the above, when sampling surface water, the lifting height is controlled by the lifting column 208 to send the water pump 1 to the sampling water layer, and then the water pump 1 is started. At this time, the water body enters the water pump 1 connected to one end of the water pump pipe 201 along the inner side of the filter box 202. During sampling, some impurities such as mud, floating objects in the water are filtered on one side by the filter net 204, and the sampled water body will be discharged through the outlet pipe 210 connected to one side of the water pump 1. For sampling work in different water layers, it is only necessary to adjust the lifting height of the lifting column 208.
