Electricity generation module is made up of center point to disk and piezoelectric patches circuit board two parts.Piezoelectric patches circuit board is piezoelectric system Into lamellar rectangular thin plate, its one end offer be connected with fixed flange needed for bolt hole, it is embedding with an anti-collision module The fixed flange of the set telescoping tube other end is bolted fixation, and makes piezoelectric patches circuit board vertical with nested telescoping tube. When single elementary cell is installed, adapter sleeve 4 is set in into 5 outer wall of standpipe first, then consolidating 4 one end of adapter sleeve The fixed flange 9 for determining ring flange 9 with 6 one end of nested telescoping tube is bolted fixation, spring 3 is set in nested flexible Outside pipe 6, and the fixed flange 9 of 6 other end of nested telescoping tube is connected into fixed.Then, by piezoelectric patches circuit board 2 offer with Fixed flange 9 is connected one end of required bolt hole and is bolted with the fixed flange 9 of 6 free end of nested telescoping tube It is fixed, and make piezoelectric patches circuit board 2 vertical with nested telescoping tube 6.By 2 other end of piezoelectric patches circuit board insertion center point to disk 1 Groove, four bolts hole and the bolt hole of recess sidewall for making 2 side wall of piezoelectric patches circuit board are mutually matched, are bolted It is fixed, and 2 end leads hole of piezoelectric patches circuit board is docked with the perforate matching of groove inner wall, wire enters center through perforate Divide to the inside of disk 1.The structure of the piezoelectric patches circuit board 2 installed and anti-collision module composition is around center point to disk 1 in revolving mirror The form arrangement of picture.The center of not connected piezoelectric patches circuit board 2 point is blocked to the perforate of 1 groove inner wall of disk by fluid sealant.

The described adapter sleeve both sides installed in standing tube outer wall can respectively with an elementary cell an anti-collision module phase Even so that multiple elementary cells are arranged in array, meet the linking requirement of actual riser post group, form the generating field of scale. 7, described 4 both sides of adapter sleeve installed in 5 outer wall of standpipe can respectively with an elementary cell one Individual anti-collision module is connected so that multiple elementary cells are arranged in array, meet the linking requirement of 5 post group of actual riser, form rule The generating field of modelling. When array is installed, then an anti-collision module by 4 both sides of adapter sleeve of 5 outer wall of standpipe respectively with an elementary cell It is connected so that multiple elementary cells are arranged in array.
3rd, the piezoelectric patches circuit board of apparatus of the present invention is equally spaced at center point to disk surrounding, and piezoelectric patches circuit board with Nested telescoping tube is vertical, the elementary cell of formation can tackle different directions flowing, make device be adapted to current direction unstable The true environment of fixed change.

Wherein：1st, center point is to disk；2nd, piezoelectric patches circuit board；3rd, spring；4th, adapter sleeve；5th, standpipe；6th, nested telescoping tube； 7th, power collector, 8, commutator；9th, fixed flange. A kind of steady pipe group vibration anti-collision can be realized and sent out using described steady pipe group vibration anti-collision and TRT Method for electrically.Sea water can occur boundary layer separation when flowing through standpipe, the vortex for periodically coming off be produced in standpipe afterbody, so as to excite The vibration of standpipe, standpipe can drive connected anti-collision block motion after there is vibration displacement, make nested telescoping tube that week to occur Phase property it is flexible；Nested telescoping tube drives connected piezoelectric patches circuit board motion when flexible, occur piezoelectric patches circuit board Reciprocal flexural deformation, produces unstable electric current, and it is whole to the commutator inside disk that erratic current Jing wires cause center point Stream, and be collected by power collector, realize generating electricity.During nested telescopic tube, because of the port screens of large and small diameter pipes The displacement of standpipe is limited, and as the structure that piezoelectric patches circuit board and anti-collision module are constituted is divided to disk in revolving mirror around center The form arrangement of picture, therefore will not collide between standpipe；When nested telescoping tube reduces, due to the presence of spring, limit The displacement of standpipe, it is therefore prevented that the mutual collision between standpipe.Therefore, this device limits the vibration position of standpipe while generating electricity Move, realize the collision-proof function between steady pipe group.
