2results about How to "Solving Detection Errors" patented technology

The utility model relates to water quality detection technical field especially a kind of water quality detection device of adjustable detection depth, including roof, the bottom of the roof is fixedly installed with two symmetrical L-shaped side plates of setting, two the L-shaped side plate is fixedly installed with the mounting plate parallel with roof between it by bolt. The utility model has the advantages of: after reaching target depth, electric push rod drives lifting plate to move up, spring reset makes protective box separate, at this time water inlet hole makes external water body and protective box internal pressure keep consistent, ensure that protective box is smoothly separated, let pH sensor completely expose and contact target water sample and carry out detection.This operation process, protective box forms physical isolation to pH sensor in moving stage, water inlet hole passes through balanced pressure and guarantees protective box to be smoothly separated, so that pH sensor can directly contact target depth water sample, solve the detection error problem caused by traditional bare sensor due to multilayer water sample mixing.

The utility model relates to the technical field of battery detection, in particular to a portable battery detection device. The device comprises a terminal processor, a shell, and a battery comprehensive tester, a thermal infrared imager, a high-resolution industrial camera, an ultrasonic assembly and a power supply device which are arranged in the shell, the positive electrode of the battery comprehensive tester is connected with the positive electrode of the waste battery placed in the shell, and the negative electrode of the battery comprehensive tester is connected with the negative electrode of the waste battery; the battery comprehensive tester is connected with the terminal processor through a first data transmission line; the thermal infrared imager is connected with the terminal processor through a second data transmission line; the high-resolution industrial camera is connected with the terminal processor through a third data transmission line; the ultrasonic assembly is connected with the terminal processor through a fourth data transmission line; the battery comprehensive tester, the thermal infrared imager, the high-resolution industrial camera, the ultrasonic assembly and the waste battery are all connected with the power supply device. According to the utility model, the waste batteries can be efficiently, comprehensively and accurately detected and sorted.
