Abstract: An artificial vertebral body includes a housing, a rotating body and a support member; an inner peripheral surface of the housing is provided with a first cooperating portion. The rotating body is rotatably disposed in the housing, an outer peripheral surface of the rotating body being provided with a second cooperating portion; the first cooperating portion can cooperate with the second cooperating part to restrict the rotation body to only rotate clockwise or counterclockwise; the support member passes through the rotating body and is screwed together with the rotating body; and the rotating body can rotate relative to the housing to drive the support member to move along the axial direction of the rotating body.

Abstract: Provided are a method and an apparatus for rechecking a defective product. The method includes: a display terminal receives sent image information of at least one detection image corresponding to the defective product (S110). The image information includes: an ID of the at least one detection image, and defect information corresponding to the at least one detection image. The defect information includes: a defect type of a defect in the at least one detection image, and defect coordinates of the defect in the at least one detection image. The display terminal displays the at least one detection image that is pre-stored corresponding to the defective product and marks the defect information corresponding to the at least one detection image according to the image information (S120).

Abstract: A bullet-screen comment data processing method is provided. The method includes: receiving bullet-screen comment data for an on-demand video played in a client; in response to determining that the on-demand video meets a preset bullet-screen comment trigger condition, screening the bullet-screen comment data based on a preset rule to obtain source bullet-screen comments; combining the source bullet-screen comments to generate collapsed bullet-screen comments representing homogenous bullet-screen comments, and sorting the collapsed bullet-screen comments to obtain a sorting result; and sending the collapsed bullet-screen comments to the client based on the sorting result, to display the collapsed bullet-screen comments on a display screen of the client.

Abstract: Disclosed is a method for recoating an RTV anti-pollution flashover coating on an insulator coated with the RTV anti-pollution flashover coating. The insulator includes an insulator body, a steel cap connected to an upper surface of the insulator body, and a steel pin connected to a lower surface of the insulator body. The method includes: (1) wiping off dirt on a surface of the insulator; (2) determining whether the insulator can be recoated; (3) performing coating by using an RTV anti-pollution flashover coating with the content of solid being 55%-65%. After coating is performed, a newly coated anti-pollution flashover coating can be closely adhered to a surface of the insulator, swelling does not occur, adhesion of the coating with respect to the insulator is not reduced, the hydrophobicity of the surface is recovered, and non-reduction of a pollution flashover voltage of the insulator is ensured.

Abstract: A floor washer cleaning device is mounted inside an opening cavity arranged at a bottom of a dustbin of the floor washer. The floor washer cleaning device comprises a roller brush assembly rotatably arranged inside the opening cavity, and a scraping board fixed at the bottom of the dustbin and located at an edge of a side of a bottom of the opening cavity. The scraping board, an inner wall of the opening cavity, and the roller brush assembly cooperatively enclose to form a negative pressure cavity communicating with the dustbin, and a suction nozzle communicating with the negative pressure cavity is formed between an inner side of the scraping board and the roller brush assembly.
