The utility model relates to the technical field of stand column mechanical arms, in particular to a heavy-load stand column mechanical arm which comprises a stand column, a sliding seat, a balancing weight, a chain and a grabbing mechanism, sliding rails are arranged on the two opposite side faces of the stand column, sliding blocks are arranged on the sliding rails on the two sides, and the sliding seat is fixed to the sliding block located on one side of the stand column. The balancing weight is fixed to the sliding block located on the other side of the stand column, the two ends of the chain are fixedly connected with the sliding base and the balancing weight respectively, a chain wheel is rotationally arranged at the top end of the stand column, the top end of the chain wheel is meshed with the chain, and the grabbing mechanism is fixed to the sliding base which is provided with a first servo motor. A driving shaft of the first servo motor is in driving connection with a first gear, the stand column is provided with a rack extending in the length direction of the stand column, the first gear is meshed with the rack, the weight of the sliding base and the weight of all components installed on the sliding base are balanced through the balancing weight, and in the lifting process of the sliding base and all the components installed on the sliding base, noise is smaller, and movement is more stable.

The present application relates to the technical field of biological monitoring, in particular to a fluorescence sensor for detecting endocrine disrupting activity in sewage and application. The present application creatively designs a Y-shaped polypeptide containing an anchoring region, a hinge region and an anti-fouling region as a structural framework, and performs directional modification at the ends of the main chain and the branch chain to prepare a multifunctional ligand-polypeptide-dye conjugate; a covalent coupling method is used to construct a high-response-efficiency, strong-anti-pollution-characteristic and stable-regeneration optical biosensor chip, i.e. a ligand-polypeptide-dye conjugate functionalized biosensor chip, then a quantum dot-nuclear receptor fluorescence probe with high sensitivity and adjustable emission spectrum is prepared, a ratio fluorescence biosensing principle based on fluorescence resonance energy transfer is proposed, and rapid quantitative detection of endocrine disruptors in sewage is realized, so that the present application has broad-spectrum specific recognition ability for certain endocrine disruptors.
