    摘要: Disclosed are an astronomical telescope stand, an auxiliary calibration method for the astronomical telescope and an astronomical telescope system. The astronomical telescope includes at least two rotating shafts perpendicular to each other, each rotating shaft is provided with an encoder; an electronic camera shooting in the same direction as the telescope to be mounted; a display screen; a processor that connects with the encoder, the electronic camera and the display screen; the processor includes an image information parsing module, an electronic image generation module and a coordinate correction module. The telescope is mounted on the stand, and the electronic camera shoots the same image as the image observed by the telescope. The image information parsing module solves the image to obtain the center coordinate and the field size of the image. The electronic image generation module generates the simulated image according to the center coordinate and the field size.

    摘要: A drain pipe structure configured for a basin, comprising a drain pipe body for water drainage, at least one connecting seat, and at least one mounting seat. The at least one connecting seat is configured to be connected to the drain pipe body to be fixed relative to an axial direction of the drain pipe body and at least one of rotation direction about an axis of the drain pipe body. The at least one connecting seat comprises a first connecting member, and the at least one mounting seat comprises a second connecting member. The first connecting member is configured to be operatively coupled to the second connecting member to enable the at least one mounting seat to operatively move along the axial direction of the drain pipe body to be fixed to a predetermined position of the at least one connecting seat along the axial direction.
