[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terminology used in the specification of the present application herein is only for the purpose of describing specific embodiments and is not intended to limit the present application.

[0045] Referring to Figures 1-4 As shown in the figure, according to the embodiment of the present application, the sediment detection device with quantitative and qualitative measurement functions comprises a pretreatment device 1, the pretreatment device 1 comprises a first box body 11 and a liquid treatment tank 3, the liquid treatment tank 3 is arranged inside the first box body 1, the liquid treatment tank 3 is connected with a liquid inlet pipeline 4, a liquid outlet pipeline 5 and a first detection pipeline 6, and the inside of the liquid treatment tank 3 is provided with a vibration component 8 and a pressure detection component 9. Among them, the liquid inlet pipeline 4 is used to transport the external sampling liquid to be detected into the liquid treatment tank 3, the liquid outlet pipeline 5 is used to discharge the sediment mixture in the liquid treatment tank 3, and the liquid treatment tank 3 is used to realize the density detection function of the sampling liquid.

[0046] Specifically, after the sampling liquid to be detected is introduced into the liquid treatment tank 3, the vibration component 8 in the liquid treatment tank 3 starts to work, so that the sediment in the sediment mixture settles, and then the weight calculation is carried out through the pressure detection component 9 in the liquid treatment tank 3, combined with the volume parameter of the sampling liquid, and finally the sediment density detection function is realized. One of the specific detection methods is provided below:

[0047] When the sampling liquid to be detected (according to a certain time) is introduced into the liquid treatment tank 3, the vibration component 8 in the liquid treatment tank 3 starts to work, the time is 3 minutes, and the frequency is 24 kHz, so that the silt in the silt mixed liquid is completely settled, and then the weight calculation is performed through the pressure detection component 9 in the liquid treatment tank 3, and the volume parameter of the sampling liquid is read through the flow meter arranged in the device. According to the formula: C=W / V. Wherein, C represents the unit sediment concentration of the river, the unit is grams per cubic meter (g / m 3 ); W represents the weight of the particulate matter in the water, the unit is grams (g); V represents the volume of the water body, the unit is cubic meters (m 3 ). Finally, the silt density detection function is realized.

[0048] More specifically, the silt mixed liquid can also be settled by the vibration component 8 to remove impurities other than silt, and then the silt mixed liquid after removing impurities is transported to the detection device 2 through the first detection pipeline 6, the external pipeline and the second detection pipeline 7 to realize the visual detection function of the sampling liquid.

[0049] Referring to Figure 1 and Figure 5 , the silt detection device with quantitative and qualitative measurement functions also includes a detection device 2, which includes a second box body 21, a second detection pipeline 7 and a visual detection component 10. The second detection pipeline 7 is arranged in the second box body 21, and the visual detection component 10 is arranged on the second detection pipeline 7. Wherein, the detection device 2 is used to extract the silt mixed liquid of the liquid treatment tank 3 through the first detection pipeline 6, the external pipeline and the second detection pipeline 7, and then visually identify the silt through the visual detection component 10 on the second detection pipeline 7, and judge various parameter indexes of the silt through machine vision technology.

[0050] Specifically, the following parameter indexes of the silt mixed liquid can be obtained through the visual detection component 10, including but not limited to:

In addition, the first detection pipeline 6 and the second detection pipeline 7 can be connected through an external pipeline to transport the liquid in the liquid treatment tank 3 to the inside of the detection device 2, so that the pre-processing device 1 and the detection device 2 can be integrated for use through the external pipeline connection, so that they or one of them can be selected for use according to the on-site environment and actual detection needs, and the use mode is flexible, and the structure of each can be adjusted according to the on-site installation conditions (for example, the height of the water inlet is selected according to the river condition), without considering different equipment selection for different river basins or different positions (for example, deep and shallow positions) of the river or sewage, realizing one machine with multiple functions and high universality.

[0059] For example, when some river conditions do not require filtering and measuring density indicators, only the detection device 2 can be used to realize the visual detection function of the sediment.

[0060] More specifically, since the sediment detection device includes the pre-processing device 1 and the detection device 2, the pre-processing device 1 is used to extract and detect the density and other parameters of the sediment in the sampling liquid, realize the quantitative measurement function, and remove the impurities other than the sediment through vibration to provide the detection device 2. The detection device 2 judges the type and size of the sediment in the sediment mixed liquid through visual detection technology to realize the qualitative measurement function. The above structure design of this embodiment makes the sediment detection device have both quantitative and qualitative measurement functions, so as to improve the confidence of the detection data. At the same time, the detection device 2 uses machine vision detection technology, which can directly judge the type and size of the sediment through the visual detection component 10, so as to significantly improve the accuracy of the parameter indicators according to the database accumulation of different river conditions.
