Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment obtained, belongs to the scope of the utility model protection.

Fig. 1-2 is referred to, the utility model provides a kind of technical scheme：A kind of ADCP adjusting apparatus, including protection under water Cage 1, it is described protection cage 1 include montant 11, crossbeam 12, footstock 13 and base 14, the upper and lower ends of montant 11 respectively with footstock 13 are fixedly connected with base 14, and the quantity of montant 11 is four, shape size all same, and its rectangular arrangement, the horizontal stroke The quantity of beam 12 is N, N>12, and its equidistant arrangement is between two montants 11, being designed to of protection cage 1 prevents aquatic organism from rushing by mistake Destroy ADCP detection.The upper end of footstock 13 is provided with motor 2, and the left end of motor 2 is connected with rotating shaft 3, described Rotating shaft 3 is located at the middle part of footstock 13, and its left end is fixedly connected with fixed cover 31, prevents the cable wire 4 in the middle part of it from skidding off, the driving Model J38Z1A (N) 40-3P of motor 2, is clockwise and anticlockwise motor, can be driven in rotating shaft 3 when motor 2 turns clockwise Cable wire 4 is wound, so as to drive ADCP7 to rise, conversely, can drive ADCP7 will be in weight block when motor 2 is rotated counterclockwise Sink under 9 pulling force, so as to reach the effect of the regulation underwater depth of ADCP, realize the measurement of multiple height water levels.Institute State the middle part of protection cage 1 and be provided with ADCP7, the ADCP7 bottoms are fixedly connected with weight block 9, the ADCP7 by cable wire 4 The heart is located on the protection perpendicular bisector of cage 1, buoyancy of the gravity much larger than the ADCP7 water being subject to of the weight block 9 so that weight block 9 Pulling force to ADCP7 is more than the buoyancy of water, and ADCP7 can sink in the case of not by steel cable stretching force.The middle part of montant 11 covers Slip ring 8 is connected to, the slip ring 8 and ADCP7 are fixedly connected with the left and right ends of buffer unit 5 respectively by cable wire 4, the buffering Device 5 includes fixed block 51, pull bar 52, piston 53, spring 54 and housing 55, the inner chamber bottom of housing 55 and the bottom of piston 53 The upper and lower ends in spring 54 are respectively fixedly connected with, the top of piston 53 and the bottom of fixed block 51 are respectively fixedly connected with pull bar 52 upper and lower ends, the piston 53 is rubber stopper, and the housing 55 is closed, and surface scribbles antirust coat, by the He of slip ring 8 A buffer unit 5 is connected between ADCP7 so that bullets of the ADCP when being shifted by current side knock in buffer unit 5 Spring 54 can pull back with piston 53 and pull bar 52 makes whole device restore to the original state, and reduces the deviation of the numerical value of ADCP7 detections. The ADCP7 tops and the middle part of rotating shaft 3 are fixedly connected with the upper and lower ends of cardo ring 6 respectively by cable wire 4, and cardo ring 6 can make ADCP7 reduces the frictional force that it connects the interface of cable wire 4 when flow action deflects.

Operation principle：First, place and connect after whole device, after ADCP7 is stable, first control the up time of motor 2 Pin rotates, and drives the cable wire 4 in rotating shaft 3 to wind, so as to drive ADCP7 risings, rising to it needs position, record detection As a result, when it rises to peak, then motor 2 is controlled to rotate counterclockwise, at this moment cable wire 4 will very to ADCP7 pulling force It is faint so that ADCP7 makes it sink by by the downward pulling force of weight block 9, records the detection data of deeper position.And work as water When stream makes the ADCP7 be shifted by side knock, the spring 54 in buffer unit 5 can pull back with piston 53 and pull bar 52 Whole device is restored to the original state, reduce the deviation of the numerical value of ADCP7 detections.

While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art, It is appreciated that these embodiments can be carried out in the case where not departing from principle of the present utility model and spirit a variety of changes, repaiies Change, replace and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
