Description

One kind is tethered at ship

Technical field

The utility model belongs to aerostatics technical field, and in particular to one kind is tethered at ship.

Background technology

It is a kind of by the lift-off of buoyance lift gas and motorless aerostatics to be tethered at ship, and empennage is the important composition portion for being tethered at ship Point, for ensureing the balance and stability that are tethered at ship vertical and horizontal.In order to reduce the construction weight for being tethered at ship, ship tail is tethered at The wing generally uses air-supported membrane structure.

Inflation empennage is fixed together frequently with the mode of welding with utricule, at present conventional tail fin design and mounting means It is that, into a sealed cavity, utricule afterbody is provided with the air bag completely cut off with utricule by tail fin design.Empennage includes exterior skin, bottom Portion's cut-parts, exterior skin and bottom cut-parts connect the seal cavity to form empennage.In the outer surface of utricule afterbody and air bag, it is located at The seam region of the two is provided with empennage mounting hole.The bottom cut-parts insertion of empennage is assembled in mounting hole, and empennage passes through with utricule Bottom cut-parts isolation.Bottom cut-parts are provided with positioned at the area segments of air bag makes the gas that empennage seal cavity is connected with air bag Hole, it is ensured that connected between the seal cavity of multiple empennages, so that convenient injection air.

Prior art is primarily present following defect：Inflation empennage is cut out with utricule by the bottom that a flexible cut-parts are empennage Piece is separated, and filling is air in empennage, and the interior filling of utricule is the buoyance lift gas such as helium.If empennage bottom cut-parts air-tightness is not It is good（Such as material defect in itself or cut cause）, the air in empennage cavity will be leaked to directly in utricule, influences utricule The purity of interior buoyance lift gas, so that being tethered at the buoyancy loss of ship.

Utility model content

In view of the above-mentioned problems, the utility model, which aims to provide a kind of gas avoided in empennage seal cavity, enters utricule Interior is tethered at ship.

The utility model solve problem technical scheme be：One kind is tethered at ship, including utricule, be connected with utricule afterbody and with The air bag of utricule isolation, the empennage being connected with utricule, the empennage include exterior skin, bottom cut-parts, and exterior skin and bottom are cut out Piece connects the seal cavity to form empennage, and tail is provided with the outer surface of utricule afterbody and air bag, positioned at the seam region of the two Wing mounting hole, the bottom cut-parts insertion of empennage is assembled in mounting hole, and empennage is completely cut off with utricule by bottom cut-parts, bottom cut-parts Area segments positioned at air bag are provided with the passage that empennage seal cavity is connected with air bag is made, and the bottom cut-parts of the empennage are extremely Include two single cut-parts layers less, the edge of all cut-parts layers is connected with exterior skin lower end edge, between adjacent panels layer Separable, the seal cavity of empennage is divided at least two cavitys by cut-parts layer.

In such scheme, the seal cavity of empennage is separated into multiple cavitys mutually completely cut off, more multiple guarantor is added Air in barrier, empennage annular seal space wants to enter utricule, it is necessary to by the barrier of multiple cavity, add sealing property, reliably Property is higher.

In a kind of specific scheme, the bottom cut-parts of the empennage include the first cut-parts layer and positioned at the first cut-parts layer bottom The second cut-parts layer, the first cut-parts layer with the welding of exterior skin lower edge form sealed empennage main chamber；

Second cut-parts layer and the first cut-parts layer edge welding, space therebetween forms the secondary chamber of sealed empennage.

In such scheme, when being tethered at ship inflation, empennage main chamber is inflated to operting differential pressure with utricule, now the secondary intracavitary gas of empennage Body is less, the close laminating of first, second cut-parts layer.With long-term use, cause the cut-parts of empennage bottom first layer air-tightness not good, Gas in empennage main chamber is no longer directly leaked in utricule, but leaks to the secondary chamber of empennage.

Further, first cut-parts layer is located at the region of utricule and is provided with and only allows gas into the of empennage main chamber One check valve；The region that the second cut-parts layer is located at air bag is unidirectional provided with only allow gas into air bag second Valve.

In above-mentioned further improved scheme, the gas of empennage pair intracavitary can only flow into empennage main chamber or capsule by check valve Body back air is intracapsular.Avoid the secondary chamber of empennage and cause to tear or gas can not be discharged because the excessive pressure of gas is excessive etc. and be existing As.

To accelerate the air intestine evacuation velocity of the secondary intracavitary of empennage, first check valve and the second check valve are equipped with multiple.

Remarkable result of the present utility model is：Inflation empennage bottom is provided with multiple cut-parts layer, forms empennage multiple Cavity, it is to avoid air is directly leaked in utricule in empennage, so that the sealing property between inflation empennage and utricule is added, Buoyance lift gas loss is directly reduced, can effectively improve and be tethered at ship performance.

Embodiment

As shown in Fig. 1~2, one kind is tethered at ship, including utricule 20, the sky that is connected and completely cuts off with utricule 20 with the afterbody of utricule 20 Air bag 22, the empennage 10 being connected with utricule 20.The empennage 10 includes exterior skin 1, bottom cut-parts 3, exterior skin 1 and bottom cut-parts 3 connections form the seal cavity of empennage 10.Set in the outer surface of the afterbody of utricule 20 and air bag 22, positioned at the seam region of the two There is empennage mounting hole, the insertion of bottom cut-parts 3 of empennage 10 is assembled in mounting hole, and empennage 10 passes through bottom cut-parts 3 with utricule 20 Isolation.Bottom cut-parts 3 are provided with positioned at the area segments of air bag 22 makes the passage that the seal cavity of empennage 10 is connected with air bag 22.

The bottom cut-parts 3 of the empennage 10 at least include two single cut-parts layers, the edges of all cut-parts layer with outside The lower end edge of covering 1 is connected, and is separated between adjacent panels layer, and the seal cavity of empennage 10 is divided at least two by cut-parts layer Cavity.

The bottom cut-parts 3 of the empennage 10 include the first cut-parts layer 31 and the second cut-parts positioned at 31 bottom of the first cut-parts layer Layer 32, the first cut-parts layer 31 forms sealed empennage main chamber 40 with the lower edge welding of exterior skin 1.

Second cut-parts layer 32 and the first cut-parts 31 edge welding of layer, space therebetween form the secondary chamber of sealed empennage 50。

The region that the first cut-parts layer 31 is located at utricule 20, which is provided with, only allows gas into the first of empennage main chamber 40 Check valve 33.The region that the second cut-parts layer 32 is located at air bag 22, which is provided with, only allows gas into the second of air bag 22 Check valve 34.

When being tethered at ship inflation, empennage main chamber 40 and utricule 20 are inflated to operting differential pressure, now in the secondary chamber 50 of empennage gas compared with It is few, the close laminating of first, second cut-parts layer.With long-term use, cause the cut-parts of empennage bottom first 31 air-tightness of layer not good, tail Gas in wing main chamber 40 is no longer directly leaked in utricule 20, but leaks to the secondary chamber 50 of empennage.Gas in empennage pair chamber 50 Body can only be flowed into empennage main chamber 50 or the back air capsule 22 of utricule 20 by check valve.The secondary chamber 50 of empennage is avoided due to gas Excessive pressure is excessive the phenomenon such as to cause to tear or can not discharge gas.
