Description
Technical field
The utility model relates to the measurement equipment, particularly a kind of bathymetric survey appearance that can make things convenient for the accurate measurement deep water degree of depth.
Background technology
On engineering, often need to measure the deep water degree of depth, but do not see the bathymetric surveying instrument that simple and practical measuring accuracy is high in the market as yet, go back the more satisfactory product of neither one and can satisfy this demand in the engineering survey.
Summary of the invention
In order to address this problem, the utility model provides a kind of bathymetric survey appearance, can let the user make things convenient for measure water dark.
The technical scheme that the utility model adopted is:
Said bathymetric survey appearance mainly by venting chew, spacing collar III, retainer plate, plexiglass tent, barometer, lifting rope, suspension hook, spacing collar I, light work plug, container, spacing collar II and taskwork plug constitute.Said container is a glass container, and said container also can adopt engineering plastics to process, but this moment should be in the bottom of said container the fixed weight piece can vertical subsidence when guaranteeing that said bathymetric survey appearance is in water.Air chamber I and air chamber II are arranged in the said container.Said spacing collar I, said spacing collar II, said spacing collar III and said retainer plate adopt engineering plastics ABS injection molded.Said plexiglass tent adopts transparent plastic injection molded.Said light work plug is processed by rubber or plastics.Said taskwork plug is processed and chrome-faced by 45 steel.Said barometer is contained in the said retainer plate.Said light work plug is contained in the right-hand member cavity of said container.Said spacing collar I be contained in the right-hand member cavity of said container and be positioned at said light work plug above, the upper surface of said spacing collar I flushes with the port of the right-hand member cavity of said container.Said taskwork plug is contained between said spacing collar III and the said spacing collar II.Said suspension hook one end is connected with said container, and the said suspension hook other end is connected with said lifting rope.During use, carried said bathymetric survey appearance through said lifting rope, at this moment, said taskwork plug moves down under action of gravity, with the vents seal between said air chamber I and the said air chamber II, contacts up to the upper surface with said spacing collar II and static.Said bathymetric survey appearance is slowly evenly put into deep water through said lifting rope; Under hydraulic action; Said light work plug quilt is pressed downward slowly; Air in the said air chamber I is compressed, and the atmospheric pressure in the said air chamber I is greater than the atmospheric pressure in the said air chamber II, along with the atmospheric pressure in the said air chamber I constantly increases; After slowly up shifting said taskwork plug onto certain distance; Will slowly open the said air chamber I of the said taskwork plug sealing of former cause and the blow vent between the said air chamber II, thereby the air than hyperbar in the said air chamber I is poured in the said air chamber II, thereby make the air pressure in the constantly approaching said air chamber I of air pressure in the said air chamber II; When pressure that the difference of the air pressure in air pressure in the said air chamber I and the said air chamber II is produced under smaller or equal to the effect of said taskwork plug at gravity, said taskwork plug moves down under the effect of gravity gradually vents seal up to keeping in the center.Said bathymetric survey appearance is continued slowly evenly to put into deep water, can constantly repeat said process.In that being put into the bottom, said bathymetric survey appearance lies low even when being inverted; After said bathymetric survey appearance is mentioned from deep water; Said light work is floating beyond the Great Wall owing to hydraulic pressure descends descends for air pressure in the said air chamber I, the interior gas of said air chamber II owing to said taskwork plug moves down under the effect of gravity the airtight air pressure maximal value that keeps constant.After the water outlet of said bathymetric survey appearance, can calculate the depth of water through said barometrical reading.Chew air and atmosphere in the said air chamber II through said venting then.Closing said venting chews and gets final product.
The beneficial effect of the utility model is:
Said bathymetric survey appearance simple structure, dependable performance, easy to use have improved the precision of measuring.
Description of drawings
Figure below in conjunction with the utility model further specifies:
Fig. 1 is the structural representation of said bathymetric survey appearance.
Fig. 2 is the inner structure synoptic diagram of said bathymetric survey appearance.
Fig. 3 is the structural representation of the amplification of said spacing collar I, spacing collar II, spacing collar III in the said bathymetric survey appearance.
Among the figure, 1. venting is chewed, 2. air chamber II, 3. spacing collar III, 4. retainer plate, 5. plexiglass tent, 6. barometer, 7. lifting rope, 8. suspension hook, 9. spacing collar I, 10. light work plug, 11. containers, 12. air chamber I, 13. spacing collar II, 14. taskwork plugs.
Suppose air tight water-tight and very for a short time the ignoring of friction of right-hand member cavity inner wall contact seal of said light work plug and said container, suppose air tight water-tight and very for a short time the ignoring of friction of left end cavity inner wall contact seal of said taskwork plug and said container.The air pressure of said air chamber I and said air chamber II when the said bathymetric survey appearance of following surface analysis is positioned at the measurement bosom in measuring process.The air than hyperbar in the said air chamber I pours in the said air chamber II; Thereby make the air pressure in the constantly approaching said air chamber I of air pressure in the said air chamber II; When pressure that the difference of the air pressure in air pressure in the said air chamber I and the said air chamber II is produced under smaller or equal to the effect of said taskwork plug at gravity, said taskwork plug moves down under the effect of gravity gradually vents seal up to sealing fully.Remember that the atmospheric pressure in the said air chamber I was P1 when said taskwork plug soon sealed blow vent fully, the atmospheric pressure in note said air chamber II this moment is P2, and note hydraulic pressure this moment is P
Water, remember said taskwork plug because the pressure that action of gravity produces is P
Heavy, remember said light work plug because the pressure that action of gravity produces is P
Gently, the note atmospheric pressure is P0, so, following relational expression is arranged:
P2=P1-P
Heavy
P1=P
Water+ P0+P
Gently,
So,
P2=P1-P
Heavy=P
Water+ P0+P
Gently-P

Remember that the reading after the said barometer water outlet is P
Meter, since this moment begin until the said air chamber II of said bathymetric survey appearance water outlet in atmospheric pressure remain constant, so,
P
Meter=P2=P1-P
Heavy=P
Water+ P0+P
