Description

TECHNICAL FIELD

[0001] The utility model relates to sewage detection field, especially a mobile sewage sampling detection device. BACKGROUND

[0002] Chemical oxygen demand (COD) refers to the quantity of oxidizing agent consumed by the organic matter in sewage that can be oxidized and decomposed by strong oxidizing agent. It is one of important indexes for evaluating the degree of organic pollution of water body and is used for indicating how much the content of organic matter in water body is. The measuring principle of COD is that in strong acid solution, organic matter in water sample is oxidized into carbon dioxide and water by using potassium dichromate as oxidizing agent. The bottom of mobile sewage is silted with mud, and the top of sewage flows fast, so that conventional sampling detection means is difficult to sample. SUMMARY

[0003] The utility model relates to a mobile sewage sampling detection device.

[0005] In the utility model, the counterweight block includes upper counterweight block and lower counterweight block, and the upper counterweight block is wide on the top and narrow on the bottom, and the lower counterweight block is narrow on the top and wide on the bottom, and the upper counterweight block and the lower counterweight block are screw thread connection.

[0006] In the utility model, the metal net middle part is equipped with the connecting hole, and the sewage sampling pipe is fixedly connected to the connecting hole.

[0007] In the utility model, the gasbag is set 4, and is arranged at the four corners of the metal net respectively.

[0008] In the utility model, the sewage sampling pipe bottom is fixedly connected to the counterweight mechanism.

[0009] In the utility model, the counterweight mechanism and the suspension mechanism are spaced apart by 20 centimeters.

[0010] Beneficial effect: the utility model is aimed at flowing sewage, adopts the cooperation of suspension mechanism and counterweight mechanism, so that the sewage sampling pipe can sample the upper middle layer water sample. BRIEF DESCRIPTION OF DRAWINGS

[0013] In the drawing, reference numerals are: 1, sewage sampling pipe, 2, sampling port, 3, mounting plate, 4, counterweight, 5, metal mesh, 6, through hole, 7, air bag, 8, connecting hole. DETAILED DESCRIPTION

[0014] Embodiment:

[0015] As Figure 1 , the embodiment provides a mobile sewage sampling detection device, which comprises a sewage sampling pipe 1, the bottom of the sewage sampling pipe is connected with a counterweight mechanism, a suspension mechanism is arranged above the counterweight mechanism, a sampling port 2 is arranged on the sewage sampling pipe between the counterweight mechanism and the suspension mechanism, the counterweight mechanism comprises a mounting plate 3, and more than three counterweight blocks 4 are detachably arranged on the mounting plate, the suspension mechanism comprises a metal mesh 5, more than three through holes 6 are arranged on the metal mesh, and air bags 7 are arranged in the through holes. The counterweight block 4 comprises an upper counterweight block 4a and a lower counterweight block 4b, the upper counterweight block is wide at the top and narrow at the bottom, the lower counterweight block is narrow at the top and wide at the bottom, and the upper counterweight block and the lower counterweight block are threadedly connected. A connecting hole 8 is arranged in the middle of the metal mesh, and the sewage sampling pipe is fixedly connected to the connecting hole. Four air bags are arranged at four corners of the metal mesh. The bottom of the sewage sampling pipe is fixedly connected with the counterweight mechanism. The counterweight mechanism and the suspension mechanism are spaced apart by 20 cm.

[0016] In use, the bottom of the sewage sampling pipe 1 is placed in flowing sewage, the counterweight block and the air bag are adjusted, the sampling port 2 is located in the middle layer of the sewage, and the sampling port 2 is prevented from being blocked by bottom silt or the sampling structure is inaccurate.

[0017] The present application provides a kind of mobile sewage sampling detection device's thought and method, the method and approach of specific implementation of this technical scheme are many, above-mentioned only preferred embodiment of the present application, it should be pointed out, for the ordinary skilled person in the prior art, without departing from the principle of the present application, can make a number of improvements and refinements, these improvements and refinements also should be considered as the protection scope of the present application. In the embodiment, each component not explicitly described can be realized using existing technology.
