The application provides a use method of a photovoltaic flexible support wind-resistant cable passing rod, and belongs to the technical field of photovoltaic supports. The photovoltaic flexible support wind-resistant cable passing rod comprises the following steps: S10: the wind-resistant cable is laid and tensioned through the passing rod at the lower part of a stabilizing cable and the upper part of a bearing cable, so that the bearing cable enters the cable passing channel from the side end opening of the passing rod; S20: the rack push-pull rod is pushed up, the two side gears are driven to rotate, the two side tooth rings are simultaneously driven to rotate to the closed state with the notch facing inward, and the bearing cable is passed along the cable passing channel; S30: the rack push-pull rod is pulled down, the two side gears are driven to rotate, the two side tooth rings are driven to rotate to the open state with the notch facing outward, and the bearing cable is released; the passing rod comprises a passing rod base, a linkage component and a line body; the cable passing channel is formed between the passing rod base and the line body; and the application can solve the problems of traditional thread winding and cable passing, such as time-consuming and labor-intensive, and low installation and construction efficiency.

The utility model discloses a sound insulation and noise reduction air duct which comprises an air guide pipe, an air inlet fan for introducing external air is installed on the air guide pipe, a composite noise reduction plate is installed in the air guide pipe, and a liquid injection hole for dropwise adding scented water is formed in the position, over the composite noise reduction plate, of the upper face of the air guide pipe. And an air outlet for exhausting air into a room is formed below the air guide pipe. According to the sound insulation and noise reduction air channel, noise can be effectively reduced through staggered arrangement of the composite noise reduction plates, air can effectively penetrate through the sound insulation and noise reduction air channel while noise is reduced, the pressure of air circulation at the S-shaped channel is reduced, wind resistance is reduced, and the ventilation efficiency is improved. In addition, scented water is injected into the polyester fiber cotton through the liquid injection hole, air can be scented while ventilation is conducted, and better experience can be brought to indoor people.

This invention provides a biological indicator device for monitoring the effectiveness of environmental decontamination. The device includes a bottle body and an insert. The bottle body contains a reagent chamber with a sealing film inside. The insert includes a bottle cap with a sealing body and a bacterial strip. A microbial barrier and a breathable component are positioned between the bottle cap and the bottle body. In its initial state, the bottle cap, the breathable component, the bottle body, and the sealing film together form a closed cavity, within which the bacterial strip is located. In its closed state, the sealing body is in sealing contact with the opening of the reagent chamber, and the bacterial strip is inserted into the reagent chamber. This invention is simple to operate and prevents external microorganisms from entering the reagent chamber during cultivation, thus improving the reliability of the test results.
