Description
Technical field
The utility model relates to a kind of hydrophone calibration support, more specifically says, it relates to a kind of vibration jet method nautical receiving set sizing stop.
Background technology
Because tripod has stable, practical characteristics, therefore used widely.As the tripod of video camera, the bracing frame of various goods products, hat rack, light of stage frame etc.But at some specific occasions, such as the actual request for utilization at underwater acoustic measurement in the reality, because the general structure of existing tripod is complicated, it is big to take up room, and the high inadequately shortcoming of adjustable-height often can not satisfy the demands, and is not too suitable.
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art, provides a kind of simple in structure, and it is little to take up room, and stands steadily the vibration jet method nautical receiving set sizing stop that highly can regulate.
The purpose of this utility model is achieved through the following technical solutions.This vibration jet method nautical receiving set sizing stop comprises crossbeam, beam seat, expansion link, retaining ring, tightens cover, column, supporting leg, mandrel etc.; Wherein three supporting legs, a mandrel are formed base; Column lower end is enclosed among the mandrel, and there is screw thread the column upper end, is connected with retaining ring; Expansion link is enclosed within the column: tighten and be placed between retaining ring and the column; Be inserted in the beam seat expansion link upper end, and beam seat is connected with an end of crossbeam.
As preferably: supporting leg ground connection one end scabbles, and the supporting leg other end is fixed on the mandrel, and three supporting legs become circumference uniform distribution, and angle between any two is 120 °.
As preferably: column lower end is enclosed within the mandrel, and the column upper end has screw thread to be connected with retaining ring.
As preferably: the level height of three supporting leg ground connection one ends of mandrel bottom distance is 120mm-180mm.
As preferably: the level height of three supporting leg ground connection one ends of mandrel bottom distance is 150mm.
As preferably: tighten and be placed between retaining ring and the column, retaining ring upper end endoporus is a bellmouth; Tighten the outside, set upper side and also be taper, and the upper end has four uniform flutings of being convenient to tighten the cover contraction.
As preferably: the bellmouth tapering of retaining ring upper end endoporus is 6 °; The taper tapering that tightens the outside, set upper side is 5 °.
As preferably: have a threaded hole that is used for fixing beam seat and expansion link relative position on the beam seat.
As preferably: crossbeam away from an end of beam seat have at least two fixedly underwater acoustic measurement with the through hole of standard hydrophone or transmitting transducer.
As preferably: the diameter of the through hole on the described crossbeam is 15mm.
The beneficial effects of the utility model are: tighten and be placed between retaining ring and the column, the rotational lock ring can compress and tighten cover, thereby expansion link is fixed on a certain ad-hoc location of column; Three supporting legs, a mandrel are formed the base of sizing stop, substructure height 150mm, like this sizing stop can with calibration tube closely and together, be convenient to measurement; Expansion link is enclosed within the column, and expansion link can move up and down in column, and can 360 ° of rotations.The rotational lock ring if retaining ring moves down, then compresses and tightens cover, and tighten cover column is compressed, thus the firmly locking of realization column and expansion link; Otherwise, between column and the expansion link gap appears then, and the two unclamps.A threaded hole is arranged on the beam seat, can the relative position of beam seat and expansion link be fixed with screw or lock handle.Crossbeam has two through holes away from an end of beam seat, and fixedly underwater acoustic measurement is with standard hydrophone or transmitting transducer, and the position of standard hydrophone or transmitting transducer crossbeam horizontal adjustment relatively.This sizing stop is simple in structure, and it is little to take up room, and stands steadily, highly can regulate, and highly is adjusted to the realization locking that assigned address can be firm, can well satisfy the request for utilization of vibration jet method hydrophone calibration.
Description of drawings
Fig. 1 is the utility model cut-open view;
Reference numeral: crossbeam 1, beam seat 2, expansion link 3 tightens cover 4, retaining ring 5, column 6, mandrel 7, supporting leg 8.
Embodiment
Below in conjunction with drawings and Examples the utility model is described further.Though the utility model will be described in conjunction with preferred embodiment, should know, do not represent that the utility model is limited among the described embodiment.On the contrary, the utility model will be contained alternative, modified and the equivalent in the scope of the present utility model that can be included in attached claims qualification.
To shown in Figure 3, the vibration jet method of Jie Shaoing generally is used to vibrate jet method with the nautical receiving set sizing stop and fixes with hydrophone calibration here, yet should know referring to Fig. 1, and the utility model also can be used for other hydrophone calibrations to be fixed etc.
Vibration jet method nautical receiving set sizing stop as shown in Figure 1 comprises crossbeam 1, beam seat 2, expansion link 3, retaining ring 5, tightens cover 4, column 6, supporting leg 8, mandrel 7 etc.; Wherein three supporting legs 8, a mandrel 7 are formed bases; Supporting leg 8 ground connection one end scabbles, the other end and mandrel 7 welding, and three supporting leg 8 circumference uniform distributions become hexagonal angle between any two, and base can stand on the ground reposefully like this.The level height of three supporting leg 8 ground connection one ends of mandrel 7 bottoms distance is 150mm.
Be inserted in the beam seat 2 expansion link 3 upper ends, and a M8 threaded hole is arranged on the beam seat 2, the beam seat 2 and the relative position of expansion link 3 can be fixed with the lock handle of a M8; Beam seat 2 welds together with an end of crossbeam 1, and crossbeam 1 other end has the through hole of two diameter 15mm, can fixing of energy converter.
