Description
Technical field
The utility model is related to for field operation and supplies for dealing with an emergency and relieving a disaster air-drop equipment, and in particular to can drop free storage
Flow container.
Background technology
During field operation and rescue and relief work, due to environmental restrictions, water and oil fuel need to drop and arrive designated area.Mesh
Preceding common parachute air-drop, its existing complicated, drift is greatly, release position is inaccurate and fluid leakage problems seriously affect
Air transport efficiency.In order to reduce impact, avoid damage product, some air-drop equipments also set air bag, thorn in internal and/or outside
The buffer units such as hedgehog formula damping shell, inflator, complicated, volume is larger and available capacity very little.In addition, existing air-drop
In fluid reservoir material, iron sheet barrel is heavy, easily gets rusty, short life, is mainly used in the storage of a small amount of water of short distance；Rubber water tank has
Poison is only used for undrinkable water；PVC coating cloth water tanks are although nonpoisonous and tasteless, foldable, light-weight, are convenient for carrying, but not
Can band water air-drop.
The content of the invention
In order to simplify air-drop equipment and be suitable for drop free, the utility model devises a kind of three-layer combined polyethylene
Rotational moulding fluid reservoir, is integrally formed, without additional bumper structure, strong shock resistance, available for drop free.
The technical solution of the utility model is：A kind of rotational moulding fluid reservoir for drop free, including tank body and fill, tapping
Mouthful, key is：The tank body is integrated the elliposoidal of rotation molding, and tank body bottom is supporting plane, and tank wall is three-layered node
In structure, including Midst density metallocene PE shock resistance outer layer, medium density polyethylene foaming middle level and high density polyethylene (HDPE) antiseepage
Layer.
The fluid reservoir uses the elliposoidal structure of rotation molding, is integrally formed, no corner angle, without additional bumper structure, with ground
Unstressed centrostigma when face contacts, and spring buffering can be formed, avoid directly impacting, improve impact resistance.Tank body uses three layers
Structure, shock resistance outer layer raw material use Midst density metallocene PE, make outer layer intensity height, toughness, rigidity good；Foam middle level by
High density polyethylene (HDPE), low density polyethylene (LDPE) and foaming agent are blended to be formed, and have the good characteristic of medium density polyethylene, can reduce tank
Body weight simultaneously absorbs impact；Antiseepage internal layer raw material uses high density polyethylene (HDPE), can form fine and close, smooth theca interna, and can root
Its technique and formula are suitably adjusted according to liquid material, food-grade polyethylene is selected when containing drinking water, contains fuel oil or chemical liquids
Can corresponding selection antiseepage, the polyethylene of corrosion resistant during body；This structure and formula not only significantly improve the intensity, tough of fluid reservoir
Property, shock resistance, can also correspond to splendid attire different liquids, so realize band liquid drop free.
Further, it is described fill, tap hole is arranged in the integrally formed inner groovy of tank surface, and this is filled, tap hole
It is semicircular protection fin that periphery, which also forms cross sectional shape,.Indent groove edge and tank body side rounding off.This structure
Directly impact can be avoided to fill, tap hole, pre- anti-cracking and anti-leakage.
Further, it is described fill, tap hole is to be embedded in screw thread hole seat in tank wall, the screw thread hole seat in rotational molding technique in advance
Sealing structure is cooperatively formed with matching thread plug.
Further, the screw thread hole seat includes polygon anticreep pedestal and is arranged on the thread bush of anticreep base central
Cylinder, anticreep pedestal periphery are evenly distributed with the main disconnecting prevention structure of " L " shape anticreep hook-forming；Screw plug is connected in screw shell.Anticreep
Pedestal is 4-8 sides shape.
Further, each " L " shape mousing-hook top is connected by fence, forms the auxiliary of enhancing screw thread hole seat intensity
Disconnecting prevention structure.
Screw thread hole seat made of metal is pre-buried in tank wall, and " L " shape mousing-hook is added using polygon anticreep pedestal
And Fence structure, screw thread hole seat can be made to combine closely with tank wall, good airproof performance, and there is higher intensity, avoid high-speed punching
Be broken or comed off caused by hitting.
Further, it is described fill, tap hole is provided with two, be respectively arranged on the implementation of port on tank body top and be arranged on
The tap hole of side.In this way, filling and pouring liquid can be easy to.
Further, the tank surface is uniformly surrounded with the broadwise reinforcing rib of protrusion, and the reinforcing rib and tank body one
It is body formed；The cross sectional shape of reinforcing rib is semicircle, and protrudes thickness and be more than 13mm.The reinforcing rib structure of rounding off, can keep away
Exempt to produce stress concentration point, and the rigidity of general product and thickness is square directly proportional, protrusion, which thickens reinforcing rib, to be effectively improved
The impact strength of water pot.
Further, for the ease of taking and carrying, the tank body side integrally formed with indent grip groove, and grasp
Groove edge and tank body side rounding off.
Further, the shock resistance outer layer thickness be 3-5mm, foaming intima-media thickness be 4-5mm, antiseepage internal layer thickness is
2-3mm.When the control of each layer thickness avoids cooling meat on the one hand, separation, on the other hand may be used caused by each layer shrinking percentage difference
While excellent mechanical property is obtained, thinned, loss of weight is realized, and then improve useful load.
Further, fluorescent belt or fluorescent powder is distributed with the tank surface.For the ease of in night and dim environment
Recognize fluid reservoir, outer layer polyethylene can be added into fluid reservoir surface wrap fluorescent belt or sprayed with fluorescent powder, or by fluorescent powder
In raw material.
The beneficial effects of the utility model are：This three-layer combined elliposoidal polyethylene rotational molding fluid reservoir, is integrally formed, nothing
Corner angle, unstressed centrostigma when being contacted with ground, and spring buffering can be formed, avoid directly impacting, no additional bumper structure, tie
Structure is simple, and the advantages of gather each layer polyethylene material, and higher intensity and shock resistance are obtained while realizing thinned, loss of weight
Ability is, it can be achieved that 200-300 meters of drop free.
