This utility model discloses a suspended solids analyzer in water, relating to the field of suspended solids measurement technology. It includes an analyzer body and a test bottle. The analyzer body has a detection hole, and a mounting base is snapped onto the detection hole. Symmetrically distributed support columns are fixedly connected to the lower surface of the mounting base, and the support columns slide against the detection hole. A support ring is fixedly connected between two support columns. The test bottle is snapped onto the support ring, and a limiting component for limiting the position of the test bottle is installed on the support ring. When testing the test bottle, the test bottle is installed into the mounting base. By placing the mounting base into the detection hole of the analyzer body, the test liquid in the test bottle can be tested. The mounting base does not affect the light source's illumination of the test bottle during the testing process, thus enabling the testing work to be completed without contact with the test bottle body. This effectively avoids the influence of water droplets, fingerprints, or other residues on the outer wall of the test bottle on the testing.

The utility model relates to the technical field of blueberry planting, in particular to an anti-bird device for blueberry planting, which is characterized in that one side of a protective frame is slidably connected with a bottom plate, one side of the upper part of the protective frame is fixedly connected with a side frame, the inner side of the side frame is rotatably connected with a winding rod, and the winding rod is wound and connected with a folding net; the bottom of the folding net is fixedly connected with the top of the bottom plate, a top frame is fixedly connected to the top of the protection frame, rotating rods are rotationally connected to the two sides of the inner side of the top frame, and all-around protection of the blueberry trees is achieved through the protection frame and the protection net. The protection net can effectively prevent birds from invading, meanwhile, irradiation of sunlight to blueberry trees is not affected, the problem that the bird repelling range of an existing bird repelling device is limited is solved, the safety of the blueberry trees is ensured, under the action of wind power, the fan rotates to drive the rotating rod to rotate, then the colored ribbon is driven to rotate, visual and auditory interference is generated, and the birds are effectively repelled.
