3results about How to "Solve the sampling problem" patented technology

The utility model provides a constant pressure oil sample extraction device which comprises a conveying line, a transformer, a vertical frame, a lifting rod, a power mechanism and a sampler, a conveying roller is arranged in the conveying line, the transformer is placed on the conveying roller, the vertical frame is fixedly arranged on the upper side of the conveying line, a fixing plate is fixedly arranged on the inner side of the vertical frame, and the lifting rod is arranged on the fixing plate. The fixing plate comprises a fixing part and an extending part, and the fixing part of the fixing plate is arranged on the vertical frame. According to the scheme, an oil sampling tool is improved, and the lifting rod is used for driving the sampler to sample in the transformer, so that the oil sampling qualification rate is greatly improved, meanwhile, a tester can perform operation by a single person, the operation is simple, the labor cost is reduced, the oil sampling efficiency is improved, and the transformer oil sampling problem is effectively solved; the sampling process of the sampler is shortened and the sampling efficiency of workers is improved in a variable-speed lifting manner.

The utility model provides a kind of hard alloy sampling device for ground mineral soil detection, it is related to soil detection device technical field, including push rod, handle, soil sampling cylinder, connecting rod, sampling drill bit and rotary handle, the push rod is vertically arranged and is connected by cross bar, handle is arranged in the both sides of push rod top, soil sampling cylinder is arranged on the cross bar between push rod lower end, connecting rod is screwed in soil sampling cylinder and is connected by screw thread, sampling drill bit is arranged in connecting rod lower end, rotary handle is installed in soil sampling cylinder upper side and is connected with connecting rod, the present application can solve the existing ground mineral soil sampling device, when hard soil layer or mineral layer in soil is encountered, there is difficult to sample in hard soil layer or mineral layer, and the problem that soil sampling after soil removal process is easily contaminated by upper soft soil.

The utility model belongs to the technical field of sewage toxicity exposure and detection, and particularly relates to an adjustable wastewater in-situ biological toxicity exposure and detection zoning device which comprises a detection shell, a partition plate which is detachable from the detection shell is arranged in the detection shell, and the interior of the detection shell is divided into a detection area and a biological chronic toxicity exposure area through the partition plate. An equipment storage box is arranged above one side of the detection shell, an aerator and a heating rod device are symmetrically placed in the storage box, and the aerator and the heating rod device penetrate through wire holes formed in the storage box through wires respectively to be connected with an external power source; the aeration machine conveys oxygen to the bottoms of the concentration detection areas and the biological chronic toxicity exposure areas through hoses, and a heating rod device of the aeration machine transmits a heat source to the corresponding detection areas or the biological chronic toxicity exposure areas through small holes in the bottom of the storage box; according to the utility model, simultaneous exposure of acute toxicity and chronic toxicity of wastewater organisms can be realized, and acute toxicity data and chronic toxicity biological samples can be obtained.
