The utility model relates to the technical field of microbial strain culture detection, in particular to a microbial strain culture quality detection device which comprises an incubator, and supporting pads are mounted at four corners of the bottom of the incubator. A culture dish is limited and fixed through a movable arc block and a limiting arc block, so that the culture dish is prevented from being poured in the culture box, and a servo motor drives a threaded rod to rotate to synchronously drive a movable plate to ascend and descend outside the threaded rod, so that a plurality of groups of bearing plates ascend to the upper part of the top of the culture box; the lifting of the telescopic frame is adjusted through the electric telescopic rod, so that the distance between the multiple groups of bearing plates is adjusted, and the problem that detection errors exist due to the fact that multiple layers in the incubator are inconvenient to detect during traditional microbial strain culture quality detection is effectively solved.

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.
