VIBRATION SOURCE Russian patent published in 2000 - IPC

FIELD: vibration seismic equipment. SUBSTANCE: invention is intended for increase of oil recovery of oil carrying fields by way of vibration action on oil pools from ground surface as well as for seismic prospecting of entrails of earth. Given vibration source has vibration exciter put on radiating platform that includes framework and plates-weights. Framework is made of two parts, each being provided with ribs of longitudinal stiffness in the form of tubes joined by means of angle pieces and reinforced by beams with straps. Tubes are tied up in package by ribs of lateral stiffness in the form of vertical supports. Parts of sectional framework are linked one to another with side butts of vertical supports and are interlinked with the aid of pairs of interacting L-shaped vertical wedges mounted on axles in side grooves of vertical supports. Plates-weights are anchored between vertical supports on straps of beams of sectional framework with the use of horizontal wedges inserted into undercuts of axles put into holes in vertical supports. Vibration exciter is fastened to plates-weights with the help of pressure screws which interact with it via supporting shoes placed in horizontal beams which are brought into shackles mounted in grooves of stepped protrusions of vertical support by means of axles. EFFECT: increased efficiency of transmission of vibrations generated by vibration source to ground, enhanced operational reliability of vibration source thanks to raised summary stiffness of radiation platform and to more uniform distribution of its mass over entire supporting surface. 8 dwg
