Description

Anti-rotation is without cable trash rack underwater camera device
Technical field:
The present invention is mainly used for the device of trash rack underwater camera.
Background technology:
The camera head for being currently used in submarine inspection trash rack is a lot, but is all existed not because pick-up lens is rotated freely Shooting situation can under water be positioned, it is impossible to the imaging inspection result that the examined face of trash rack is stablized is recorded, in addition All under water 80 meters or so of trash rack, the signal power source cable that camera head is carried is pulled off under Gravitative Loads, causes figure As that cannot transmit and to the out of control situation of pick-up lens.Therefore, hydroelectric field is badly in need of one kind can neither rotate freely, The underwater camera device of cable can not be broken because of signal power source cable deadweight problem again.
The content of the invention:
The present invention is directed to propose the device that a kind of anti-rotation is checked without cable trash rack underwater camera, it is characterized in that, in lifting Axle intermediate symmetry is fixed with left lifting rope sheave and right lifting rope sheave, and lifting shaft left end passes through lifting axis hole and is fixed on left fulcrum bearing On lifting decelerator output end be linked together, lifting motor is fixed together with lifting decelerator, lifting shaft right-hand member with it is solid The lifting axle bearing being scheduled in right fulcrum bearing is linked together;Left lifting wire rope one ends wound is another on left lifting rope sheave End is fixed on the left suspension ring of left suspension bracket, and on right lifting rope sheave, the other end is fixed on the right side and hangs right lifting wire rope one ends wound On the right suspension ring of frame, left suspension bracket and right suspension bracket are symmetrically fixed on square frame beam, and square frame beam two ends are respectively provided with left directive wheel and the right side Directive wheel, the connection rotating shaft with limiting stand is fixed on left wheel frame after passing through square frame beam left end and left spring, left wheel frame Another side be fixedly arranged above left universal wheel, the lower section of left wheel frame is equipped with left roller by left roller support, with limiting stand Connection rotating shaft through being fixed on right wheel frame after square bearer right-hand member and right spring, the another side of right wheel frame is fixedly arranged above Right universal wheel, the lower section of right wheel frame is equipped with right roller by right roller support, and a pair left movable pulleies are by sliding wheel shaft mounted in T Template left end, by sliding wheel shaft mounted in T-shaped plate right-hand member, T-shaped plate riser passes through posterior end in the middle of square frame beam to a pair right movable pulleies The bucker of multiple illuminating lamps, battery, video memory, pick-up lens and camera lens head-shield is fixed with, is moved left carrying The reductor that moves left of motor is fixed in left fulcrum bearing, and make to move left output end of reducer connection moves to left moving axis through moving to left Shaft hole, moves to left moving axis and is fixedly arranged at the front end with and move left rope sheave, moves to left the one ends wound of running rope on rope sheave is moved left, and moves to left running rope The other end T-shaped plate left end is fixed on by left directive wheel and left suspension bracket;Consolidating with the reductor that moves right for moving right motor It is scheduled in right fulcrum bearing, make to move right output end of reducer connection moves to right moving axis through shaft hole is moved to right, and moves to right moving axis front end It is fixed with and moves right rope sheave, move to right the one ends wound of running rope on rope sheave is moved right, moves to right the other end of running rope by right guiding Wheel and right suspension bracket are fixed on T-shaped plate right-hand member.
What the technical scheme that the present invention is provided was reached has the technical effect that such:As trash rack surface has hung many floatings During thing, the flow by trash rack water will be influenceed, especially in the trash rack part of deepwater regions.Need to check in trash rack During floaters on surface, device of the present invention is placed on above water inlet, i.e. influent side.Control lifting motor passes through left liter Drop rope sheave and right lifting rope sheave square frame beam of the decentralization with illuminating lamp, pick-up lens and bucker, are also equipped with storing in bucker Battery, video memory.Control moves left motor and moves right that motor makes to move to left running rope and to move to right running rope synchronous with square frame beam, just The left wheel frame and right wheel frame of grid beam arranged on left and right sides enable square frame beam vertically to move down in the presence of left roller and right roller, Left spring and right spring provide a normal pressure for left roller and right roller simultaneously, prevent current other side's grid beam from moving down direction Influence.Left roller and the deadweight of right roller make left and right roller move down direction more than the frictional force that left and right spring is produced by spring force It is always maintained at perpendicular to horizontal plane.T-shaped plate is placed on square frame beam interposition by a pair left movable pulleies and a pair right movable pulleies Put and T-shaped plate riser passes through width controllable in the middle of square frame beam, square frame beam and left and right movable pulley group limit the water of T-shaped plate Lower rotation, bucker is integrally fixed on T-shaped plate riser again, therefore bucker cannot rotate under water, also just solve shooting The technical problem that camera lens is rotated freely under water;Battery is set in bucker, so that it may save pick-up lens and illuminating lamp service cable. Move left motor and move right motor by control and rotate backward, so that it may so that bucker is moved left and right on square frame beam, so that Realize to the comprehensive imaging inspection of trash rack.It is additionally provided with bucker into water sensor and depth transducer, it is possible to realize Device automatically turns on pick-up lens when entering water, pick-up lens is closed during water outlet, can just be recorded not according to depth transducer The situation of floating object is intercepted with depth trash rack surface, there is provided give trash rack attendant, so that attendant examines according to device Record case is looked into determine to carry grid task.
Technical scheme proposed by the invention is rational in infrastructure ingenious, practical, with novelty and creativeness, will be extensive Various operating modes are imaged for hydroelectric power plant's submarine inspection.
