ГИДРОТЕХНИЧЕСКИХ СООРУЖЕНИЙHYDROTECHNICAL STRUCTURES
Изобретение относитс к механичес кому оборудованию гидротехнических сооружений. Известна сороудерживающа решетка гидросооружений, состо ща из вертикальных и горизонтальных стержней 1 Известна также сороудерживающа решетка гидротехнических сооружений, включающа закрепленные на каркасе вертикальные стержни и св зи 12. Недостатком известных решеток вл етс резонансное колебание отдельных стержней с узлами колебаний в местах прохода промежуточных св зей , происход щее вследствие одинако вости свободных пролетов стержней между ст жкой. Цель изобретени - повьшение надежности работы путем уменьшени резонансных колебаний стержней. Указанна цель достигаетс тем, что она снабжена упорами, закрепленными на каркасе и взаимодействующими С концами св зей, а соседние св зи расположены под углом друг к другу. На чертеже показана сороудерживаю- ща решетка. Решетка состоит из стержней 1, св зей 2, закрепленных на каркасе 3 пргсредством опорных св зей 4, и хомутов 5. На каркасе 3 напротив концов св зей 2 закреплены упоры 6. Соседние св зи 2 расположены под углом друг к другу. . Решетка работает следующим образом . При пропуске воды синхронное колебание (резонанс) стержней уменьшаетс за счет различной длины пролетов вследствие непараллельной установки соседних св зей. Кроме того, колебани стержней уменьшаютс за, счет взаимодействи концов св зей 2 с упорами 6. Предлагаема сороудерживающа .решетка позвол ет уменьшить влениеThe invention relates to mechanical equipment of hydraulic structures. The hydraulic debris lattice is known, consisting of vertical and horizontal rods 1 occurring due to the uniformity of free spans of rods between the tie rods. The purpose of the invention is to increase the reliability of operation by reducing the resonant vibrations of the rods. This goal is achieved by the fact that it is provided with stops fixed to the frame and interacting with the ends of the links, and the neighboring links are angled to each other. The drawing shows a trash rack. The lattice consists of rods 1, links 2, fixed on the frame 3 by means of supporting links 4, and clamps 5. On frame 3 opposite the ends of the links 2, stops 6 are fixed. Neighboring links 2 are angled to each other. . The lattice works as follows. When water passes, the synchronous oscillation (resonance) of the rods is reduced due to the different lengths of the spans due to the non-parallel installation of adjacent links. In addition, the vibrations of the rods are reduced due to the interaction of the ends of the links 2 with the stops 6. The proposed trash grate allows to reduce the phenomenon
