The invention discloses a method for extracting active components for algae inhibition from Acorus calamus L tubers. According to the invention, an organic solvent is directly used to extract the active components so as to obtain the algicide, or the organic solvent is used for sequential extraction to obtain the algicide. The direct extraction method of the organic solvent comprises the following concrete steps of: extracting washed, dried and crushed Acorus calamus L tubers for 2-5 times respectively by using petroleum ether, ethyl acetate and anhydrous ethanol, filtering, and condensing to obtain the active components A, B and C for algae inhibition. The sequential extraction method of the organic solvent comprises the following concrete steps of: extracting by the use of anhydrous ethanol to obtain an extract C, dissolving the extract C in 80% of a methanol aqueous solution, carrying out isopyknic extraction for 2-3 times by the use of petroleum ether, condensing the petroleum ether layer to obtain a first active component for algae inhibition, diluting residual methanol aqueous solution to 50% by the addition of water, carrying out isopyknic extraction for 2-3 times by the use of ethyl acetate, and condensing the ethyl acetate layer to obtain a second active component for algae inhibition. The extraction method is simple and easy to operate. The extracted active components, which are used as the algicide, are cheap and nontoxic, require low cost, and are suitable for practical popularization and application. The algicide can be used without the restrictions of region, solar term, temperature and the like.

The invention relates to the technical field of air conditioners, in particular to an external air conditioner wind blocking component. The external air conditioner wind blocking component comprises an arc-shaped wind baffle and a connecting rod and further comprises a second grade wind baffle. Both ends of the connecting rod are respectively connected to an air conditioner shell and the second grade wind baffle, the arc-shaped wind baffle is connected to the connecting rod, a connecting position between the arc-shaped wind baffle and the connecting rod is located between two ends of the connecting rod, and the arc-shaped baffle is of a hollowed structure. During refrigeration of the air conditioner, part of air out from the air conditioner impacts the arc-shaped wind baffle and is blown out upwards and backwards from the edge of the arc-shaped wind baffle and gaps of the air conditioner shell, the other part of air impacts the second grade wind baffle after passing through the arc-shaped wind baffle and is blown out from an outlet formed between the second grade wind baffle and the arc-shaped wind baffle, such that the air out from the air conditioner is diffused to a wider region, cold air accumulated around the air conditioner is reduced, and further the refrigeration stopping time of the air conditioner is delayed compared with prior art, such that a room temperature is close to a preset refrigeration temperature as much as possible.

The invention discloses an error detection device for a hourglass worm, comprising a body, a spindle unit and a measuring unit, wherein the spindle unit comprises a spindle servo motor, a spindle, a workpiece fixture to be measured and a tailstock; the spindle servo motor drives the spindle to rotate; the workpiece fixture to be measured is fixedly matched with the spindle in the circumferential direction; the measuring unit comprises a base, a rotating table, a measuring contact, a data acquisition system and a computer; the rotating table is arranged on the base in the manner of rotating around a z-axis; and the measuring contact is arranged on the rotating table in the manner of adjustable position along an x-axis, a y-axis and the z-axis and can rotate around an axis parallel to the z-axis. The coordinate measurement can be carried out for the hourglass worm by adopting the arc measuring method, the line by line measurement can be carried out, the efficiency is higher than that ofthe point by point measurement in the prior art, the influences of subjectivity of human intervention and mechanical error of the standard worm on the detection results are avoided, as different types of measuring contacts are adopted, various errors of the worm can be accurately detected, and the universality is strong.
