Abstract
The utility model provides a device for keeping postures of an underwater instrument, which can keep the underwater instrument vertical. The technical scheme includes that the device comprises an outer ring, a middle ring, an inner ring and two annular mounting racks, the inner ring and the middle ring are connected via two shafts and bearings which are symmetrical arranged, the middle ring and the outer ring are connected via two shafts and bearings which are symmetrically arranged, the shafts are orthogonal mutually, and the two annular mounting racks are fixed on the inner ring and are orthogonal mutually. When a subsurface buoy drives the outer ring to incline to an optional direction, the inner ring and the middle ring rotate back and forth, so that the instrument always keeps vertical, and the device is safe and reliable in use, and meets requirements on postures of the instrument.
Description
Technical field
The utility model relates to instrument under water, specifically, relates to a kind of device of instrument under water being installed and being guaranteed the instrument attitude on subsurface buoy.
Background technology
At present, the underwater exploration technical development of China is rapid, and the instrument of measuring various key elements under water is various informative.In order to satisfy measurement index, various instruments under water all have different requirement to working environment.In order to guarantee the instrument normal operation, the submerged buoy that carries instrument under water is also various.
Many instrument requirement are more little good more at the inclination angle of vertical direction, proposed the inclination angle scope of regulation, surpass this scope, and instrument is difficult to normal operation.In order to satisfy this index, the submerged buoy of instrument meets the demands to require to carry under water usually.For example, key elements such as the size of submerged buoy, shape, drag coefficient, buoyancy through series of computation and experiment, make submerged buoy satisfy the inclination angle requirement of vertical direction under water, thereby make the attitude of instrument be able to satisfy.Sometimes, submerged buoy will carry other instrument and equipments, and key elements such as the volume of equipment, weight, installation are restricted the change of key elements such as submerged buoy size, shape, drag coefficient, buoyancy.Therefore, a kind of vertical device that can keep instrument of design is very necessary.
Summary of the invention
The utility model provides a kind of device of instrument attitude under water that is used to keep, and it can realize keeping under water that instrument is vertical state.
The purpose of the utility model provides and a kind ofly is installed on the subsurface buoy and guarantees the device of instrument attitude under water, to remedy the deficiency of prior art.
In order to achieve the above object, the utility model provides a kind of device of instrument attitude under water that is used to keep, and comprises outer shroud, middle ring, interior ring and two annular arrangement erecting frames; Ring is connected with bearing through two axles with middle ring in said, and two axles and bearing are symmetrical set, and middle ring is connected with bearing through two axles with outer shroud; Two axles and bearing are symmetrical set; And said axle and axle quadrature, two annular arrangement erecting frames are fixed on the said interior ring, and two annular arrangement erecting frame quadratures.
In the technical scheme of the utility model, also have following technical characterictic:
Said outer shroud is provided with at least two hangers.
Instrument is hung on erecting frame, and said whole device is fixed on the submerged buoy through the hanger on the outer shroud.
Be provided with counterweight in annular arrangement erecting frame bottom.
The utility model is on the basis of existing submerged buoy, and it is conceived basically and between instrument and submerged buoy, installs the gimbaling that makes instrument keep vertical state additional, when submerged buoy when any direction tilts, it is vertical that instrument can keep all the time.
The utility model comprises outer shroud, middle ring, interior ring and erecting frame; Ring is connected with bearing through axle with middle ring wherein; In ring spool be connected through another with outer shroud with bearing, and two axles are quadrature, erecting frame is screwed on interior ring; Instrument is hung on erecting frame, and whole device is fixed on the submerged buoy through the hanger on the outer shroud.
The utility model guarantees that when three flat-shaped attitudes of environmental protection water holding the center of gravity of interior ring and instrument guarantees that it has the moment that returns on the vertical direction below three ring horizontal surfaces.When the hoop any direction tilted outside submerged buoy drives, interior ring and middle ring rotate back and forth, and make instrument remain vertical attitude, and be safe and reliable, satisfied the requirement of instrument to attitude.

Wherein, 1, hanger, 2, bearing, 3, axle, 4, nut, 5, outer shroud, 6, middle ring, 7, interior ring, 8, annulus frame erecting frame, 9, instrument, 10, bearing, 11, axle.
The specific embodiment
Like Fig. 1, shown in Figure 2, the utility model comprises outer shroud 5, middle ring 6, interior ring 7 and erecting frame 8, wherein in ring 7 be connected with bearing 2 through two axles 3 with middle ring 6, two axles 3 and bearing 2 are symmetrical set.
In ring 6 is connected with bearing 10 through two axles 11 with outer shroud 5, two axles 11 also are symmetrical set with bearing 10, and an axle 3 and 11 quadrature, promptly the angle of spools 3 axis and spools 11 axis is 90 °.Two annular arrangement erecting frames 8 are screwed on interior ring 7, and two annular arrangement erecting frames 8 also are the quadrature setting.
Ring was 7 li in above-mentioned annular arrangement erecting frame 8 vertical inscribes were installed in, and the length that instrument 9 is hung should be less than the diameter of erecting frame 8, and instrument 9 bumps with middle ring 6, the outer shroud 5 of rotation in the time of can avoiding submerged buoy to tilt like this.
Above-mentioned outer shroud 5, middle ring 6, interior ring 7 are when keeping horizontality, and the center of gravity of interior ring 7 and instrument 9 guarantees that it has the moment that returns on the vertical direction below three ring horizontal surfaces.When submerged buoy drives outer shroud 5 when any direction tilts, middle ring 6 and interior ring 5 are around axle 11 rotations, and interior ring 5 is around axle 3 rotations, and interior ring 7 and middle ring 6 rotate back and forth, and make instrument 9 remain vertical attitude.
Each mechanical component all adopt stainless steel material to make, thereby prevent its underwater corrosion, make its long-term use under water.
As variation, can be provided with counterweight in annular arrangement erecting frame 8 bottoms, counterweight is not shown, and instrument 9 is hung at annular arrangement erecting frame 8 middle parts.
The above only is the preferred embodiment of the utility model, is not to be the restriction of the utility model being made other form, and any professional and technical personnel of being familiar with possibly utilize the technology contents of above-mentioned announcement to change or be modified as the equivalent embodiment of equivalent variations.All the utility model technical scheme contents that do not break away to any simple modification, equivalent variations and remodeling that above embodiment did, still belong to the protection domain of the utility model technical scheme according to the technical spirit of the utility model.
