Curved test piece making device for hydraulic model

Abstract

The invention discloses a device for manufacturing an arc test piece for a hydraulic model. The device comprises a horizontally arranged sliding rod, a bracket equipped with a horizontal steel beam guide rail, and a support equipped with a vertical rotating shaft, wherein a slideway trolley capable of sliding along the steel beam guide rail is mounted on the bracket equipped with the steel beam guide rail; one end of the sliding rod is fixed at the upper end of the rotating shaft of the support; the other end of the sliding rod is inserted into the slideway trolley; when the slideway trolley slides on the steel beam guide rail, the length, inserted into the slideway trolley, of the sliding rod can be adjusted at any time, so that the sliding rod can follow the slideway trolley to rotate around the rotating shaft along with the moving of the steel beam guide rail; and a scraper matched with the arc test piece is fixed at the middle position of the sliding rod, so that a needed mold can be manufactured as required. Especially for manufacturing of arc models, the device is convenient and simple to operate, and high in stability; the arc models of different shapes can be manufactured according to various test molds; and the practical value is relatively high.

Description

technical field [0001] The invention relates to a test piece making device, in particular to a curved test piece making device for a hydraulic model. Background technique [0002] When processing the physical models of hydraulic structures such as sluices, gravity dams, and arch dams, it is necessary to make weir surfaces. Weir surfaces of different dam types are usually realized by manual plastering. Its disadvantages are low accuracy, time-consuming and labor-intensive, especially for arc-shaped weir surfaces, and relatively accurate simulation results cannot be obtained. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a device for making an arc-shaped test piece for a hydraulic model, which can be made according to a given weir surface curve, and is easy to operate and has good stability. [0004] In order to solve the above-mentioned technical problems, the technical solution adopted by the present invention...
