Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further explained below.
Referring to fig. 1 to 3, the arrangement structure of the coarse-grid trash rack for the pump gate comprises two groups of coarse-grid trash racks 1, in this embodiment, the number of the coarse-grid trash racks 1 is two, the two groups of coarse-grid trash racks 1 are respectively a first coarse-grid trash rack 10 and a second coarse-grid trash rack 20, an integral bearing platform 30 is arranged on each group of coarse-grid trash racks, the two groups of coarse-grid trash racks 1 are arranged on the integral bearing platform 30 in a symmetrical structure, each group of coarse-grid trash racks is arranged in a circular arc structure to form a V-shaped structure, a water inlet tank partition pier 40 is arranged on the same side of each group of coarse-grid trash racks, vertical columns 50 for fixing the coarse-grid trash racks and supporting an upper traffic bridge are arranged on the integral bearing platform 30 at intervals, and a connecting component 60 connected with the coarse-grid trash racks is arranged on the vertical columns 50. The connecting assembly 60 comprises a section steel tie rod 61 fixed on the upright 50 and a slot section steel 62 arranged on the section steel tie rod 61 and used for inserting the coarse grid trash rack, wherein the slot section steel 62 is preferably I-shaped steel or channel steel. Specifically, the one end of shaped steel tie rod 61 is fixed on stand 50, and the other end and the draw-in groove shaped steel 62 of shaped steel tie rod 61 are connected, and the thick check trash rack of accessible inserts in the draw-in groove shaped steel 62 bayonet socket, plays the effect of fixed thick check trash rack. Through welded fastening between shaped steel tie rod 61 and the draw-in groove shaped steel 62, steel shaped tie rod 61 need adjust the draw-in groove shaped steel 62 well accurately before the welding, ensures that thick check trash rack installation is convenient and form convex structure and arrange the effect.
