Abstract

The invention relates to a cover suitable for use on a liquid containing reservoir. The cover is composed of an envelope of porous material. The envelope is subdivided into discrete independent compartments. The compartments each have access to the internal volume for purposes of receiving a charge of hollow spheres. A centrally disposed collection member is positioned at the intersection of the independent compartments. This position is effectively the centre of mass of the cover once charged with spheres and permits expedited positioning and adjustment of the cover on the surface of the liquid container. The independent compartments facilitate controlled consolidation of the spheres therein and allow for simple positioning and removal of the cover which was challenging with prior art arrangements. The latter typically had to be folded or rolled causing manipulation difficulties and causing potentially hazardous situations during manipulation. Advantageously, the present invention provides all of the benefits typically associated with spherical geometry in terms of precipitation run off and further provides for significant insulation capacity for the cover.

Description

Container lid

Technical field

The present invention relates to a kind of lid that is used for cistern or container; It is suitable for the purpose receiving fluids material with storage; And more specifically, the present invention is directed to a kind of lid, and be placed on the cistern and more easily and take off from cistern with heat-insulating property of improvement.

Background technology

Be flooded with the lid that is used for cistern or container in the prior art, and those are suitable for the lid as the aquatic bird bar.In the situation of back, for this purpose and comprehensive covering of being used for water body, some companies propose to use floating ball body.Such example can find in Torex company that it provides ball float pond lid, has to prevent the effect of birds in the pond landing.Generally, ball or spheroid are made up of high density polyethylene (HDPE) (HDPE), and its inside is soaked with the carbon black that is used for the stable function of ultraviolet ray (UV).Find that this ball is particularly useful,, and ball self is only had slight infringement because spherome surface can withstand snow, wind and the sun.Other mechanisms in this field comprise Euromatic, and it has the trade mark of Bird Ball.Other mechanisms in the field comprise Advanced Water Treatment Technologies (AWTT), and it provides high performance unsteady lid, are made up of anti-ultraviolet pure HDPE, and trade mark is Armour Balls.

These spheroids have obvious practicability, yet the fact that their all institutes will suffer is that they are loose a piles, therefore can become from a group in the position that they are laid and separate.In addition, these balls can be moved by bigger animal, thereby from the dispersion that becomes of main group body.This has obviously defeated has the purpose that required pond hides, and has increased the cost of arranging spheroid again.

In order to overcome these shortcomings, prior art has been considered the substitute according to the shape of buoyancy aid.Example that one of them is such such as U.S. Patent number 3,993,214 are given Usab on November 23rd, 1976.This reference paper has instructed the lid of an open liquid surface, is made up of a plurality of pyritohedrons.It can be hollow or solid that this owner of a patent has instructed dodecahedron, but is processed by structural foam, and the proportion of structural foam approximately is the tintometric half the of its placement.The advantage of this layout is that this dodecahedron provides a plurality of clearly, therefore do not have any voidage, and this can occur under the situation of spheroid.Therefore, one basically completely, impermeable surface appears at the top of liquid.Though useful, this device seems that constituent material is very expensive, and exist under the situation of freezing precipiation and possibly can't operate best.

Be created in United States Patent (USP) 7,387 by changing form of instructing of Usab, in 473, give Smith on June 17th, 2008.The owner of a patent provides a kind of apparatus and method, is used to make unsteady lid.This stipulates that openly system has a plurality of buoyancy aids, and each has by a plurality of and the fixed shape of margin, and wherein each limit is formed by two crossing faces.Buoyancy aid in use, part is dipped in the liquid, makes at least a portion of first of the buoyancy aid of winning touch at least a portion of first of second buoyancy aid, between flow surface and environment, to form seamless basically barrier.This structure is the same with the structure that Usab supra instructs, and can be subject to identical scope.

Give on January 1st, 2008 in people's such as Kruse the United States Patent (USP) 7,314,564 and instructed a kind of method that is used for treat liquid.This method is introduced a kind of lid, and it has a plurality of hollow bodies that are placed in the waste water surface.Each hollow body is suitable for floating on the waste water surface, and has continuous outer surface, and enough quality, makes 30% being exposed in the air to 70% of outer surface of hollow body.

About the spherical geometries of hollow body, perhaps arbitrarily these hollow bodies are put into the attempt that the permeability skin is used to solidify purpose, all do not have to discuss.

Turning to publication number is 2006/0005830 U.S. Patent application, is disclosed on January 12nd, 2006, and the application people be Rosene etc., discloses a kind of floating solar ability pond heater (floating solar pool heater).The device of discussing in open is structurally quite conventional, and, though independent opening is provided, have no about having, for example, the guide of the use of the lid of hollow ball is although this lid provides heat-insulating property really.

Fish is the 4th, 373, but instructed a kind of filling structure in No. 462 United States Patent (USP)s.In this was open, the owner of a patent provided a kind of floating, flexible structure, and it can be by liquid-filled.This structure is limited the fixing lamellar body of latasuture, and this seam provides buoyancy by stranded ball.Ventilating opening is arranged on the top of container, and the mesh bag that thereunder has a filling spheroid to be to keep gas passage, and spheroid provides the horizontal pipeline of the net of buoyancy to keep fluid to flow, to drain through flexible pipe.The purpose of this structure is to reclaim the oil that overflows on the water body in large surface.

In more detail; The reference paper of Fish uses the spheroid of floating characteristic; And do not allow the upper strata of " lid " closely to be contacted by lower floor, increasing " void space ", " void space " is considered to serve as and makes material the floating container of flow surface (target is to be recovered in the oil slick of the water surface etc.).Spheroid also is inclusive in the tubular reticulum, to forbid " bunching up " in the zone between last liner and lower liner.This structure does not have the real practicality as the lid of the cistern of the fluid that is suitable for holding predetermined.As more in addition, this structure is not stood when needs, from the water body that it is laid, settles fast and removes.This is especially true for fluid container.

The other variation of lid and camel comprises the 3rd, 102, the 902, the 4th, 749, the 606 and the 7th, 789, and those structures that instruct in No. 043 United States Patent (USP).

Obviously, prior art has proposed a large amount of useful structures; Yet these structures also not exclusively are suitable for from the simple arrangement on the surface of fluid cistern and remove, and these structures also provide and avoid surfaces contaminated protection, insulating power and reduce the evaporation of fluid to environment.Therefore, hope to have the structure of lid and the system of the lid of the limitation that overcomes prior art.Useful is that the use net has been merely and has held spheroid, and had no other impermeable membrane embraces ball or separation net (containment netting) as the upper and lower barrier.

In addition, use network capacity to receive spheroid, install and remove from fluid container being easy to, this spheroid can be valuably in order to the insulation purpose, and net is as preventing that foreign material or wildlife/aquatic bird from getting into the barrier of container.The present invention has satisfied this needs.

The target of one embodiment of the present of invention is that a kind of improved lid will be provided, and is applicable to the cistern or the container that are suitable for receiving fluids, and a kind of system that covers this structure is provided.

According on the other hand according to an embodiment of the invention, a kind of lid that is used for container is provided, it comprises the device that is used for providing to each interlayer of said interlayer passage, said interlayer is suitable for keeping hollow ball, to said lid heat-insulating property to be provided.

About lid, the use that has been found that HDPE is effective especially for constituting spheroid, net and being used for opening releasedly the material of net.

In a preferred embodiment, lid is made up of a plurality of discontinuous interlayers, and interlayer is suitable for receiving the filling of hollow ball, and hollow ball can be 4 inch diameters as an example.Each interlayer will provide access point, so that control has the net or the Web materials of spheroid.In case lid is in suitable position, this access point can be by materials with function sealing suitable, that can not influence lid.

It is especially easily that the central jockey of the central authorities' intersection that is arranged on each interlayer is provided.For example, comprise the place of four interlayers at lid, the infall that is placed in all four interlayers is concentrated in central connection meeting.This is for being favourable to arrange that purpose is handled lid, because when being removed equally or settling, the central point is actual to be the barycenter of lid.This also has a tangible benefit to be; Be used to remove when locating again when taking away lid; Allow lid to take vertical form of assembling unified object (vertically gathered consolidated article), and the lid that need not roll, it is owing to prior-art devices.

This lid preferably uses in the cistern container, yet this technology is not limited to this environment; This device can easily be used for pond, pond etc. and use.Under latter event, expect that the cap structure of some controlled dimensions can be combined in together, to form a bigger lid, be used for open water body, wherein need characteristic of the present invention.

Summary of the invention

On the other hand according to an embodiment of the invention, a kind of surface cover is provided, be used to cover the surface of containing liquid, comprising:

The ground floor of porous flexible material and the second layer are in the relation of stacking, and connect on the edge of, between the ground floor and the second layer, limit a plurality of discontinuous interlayers, and said interlayer is suitable for keeping hollow ball, so that heat-insulating property is provided for said lid; And

Autonomous channel device in each interlayer is to provide passage to interlayer; And

Be arranged on the hollow ball in each interlayer, so that heat-insulating property is provided for said lid, said porous flexible material and said spheroid have the proportion less than water, and be floating to guarantee in the container of water.

About spheroid used in this invention, the spheroid by the aforesaid Torex manufactured of this paper is suitable for the object of the invention.About porous material, just net or net for the purpose of holding, equally obviously have the size less than the hole of sphere diameter.The size in the hole of porous material or the size of mesh can be any suitable dimensions scopes, from for example 1 millimeter to 10 millimeters or more than.This depends on the diameter that is filled into the outer field spheroid of Web materials.This spheroid is limited, and is particularly useful for the insulation purpose.This is for storing in the operating point, and for example water has significant effect.From some purpose, for example,, hope to keep water temperature, to avoid the extra expense that adds hot water again at ore deposit point or hydrocarbon processing stand.

In order to increase the heat-insulating property of the lid that holds spheroid, this paper hopes that the spheroid of different size can be used for providing spherical and distributes, and wherein interstitial volume is reduced.In term (vernacular), if only use single diameter sphere to be used for filling porous material outer layer, that the interstitial volume of significant quantity will occur; Certainly; Interstitial volume causes potential evaporation of liquid, and through passive radiation, causes the loss of heat.Through the spheroid of different size is provided, interstitial volume can be reduced, and therefore increases area coverage.The structure of discussing in this and the prior art forms contrast, and promptly the 3rd, 993,214 and the 7th, 387, those structures described in No. 473 United States Patent (USP)s, in the latter's device, the degree of flexibility between contiguous body can be as the spheroid freedom.It is low-down that dodecahedral situation is considered to efficient; Because parallel surface contacts with each other, and be accompanied by freezing precipiation, these faces will significantly depart from each other; Destroy spheroid itself potentially; And causing large-area body to be frozen in together, this is that sphere can disperse precipitation on the contrary because body does not have the fact of sphere advantage.

Describe, in general terms the present invention, now will be with reference to accompanying drawing, it shows preferred embodiment.

Embodiment

Referring now to Fig. 1, be depicted as first embodiment of lid, whole with numeral 10 representatives.This lid comprises the ground floor 12 of porous flexible material, and it overlays on the second layer 14 of porous flexible material.The ground floor 12 and the second layer 14 combine near 16 through suitable fixture (not shown) on the edge of.Suitable fixture can be to sew up, etc.

Through being mingled with stitching 18 a plurality of discontinuous interlayers are set.This stitching can be to sew up continuously or interrupted the stitching.This is divided into

independent interlayer

20,22,24 and 26 with liner 10.In the example as shown in fig. 1, four interlayers 20 to 26 are arranged.Each of interlayer 20 to 26 comprises the autonomous channel, through, for example, respectively with respect to the

otch

30,32,34 and 36 of interlayer 20 to 26.The suitable stitching of these autonomous channel otch 30 to 36 usefulness can be closed once more, and as represented about element 18, the element 18 before this paper is defined as sews up 18.

Float element 38 is arranged in the independent interlayer 20 to 26 through access incisions 30 to 36, is being spheroid shown in the example.Spheroid 38 through example, possibly comprise four inches spheroids of hollow carbon black.Find through sphere is provided: reached high insulating value, and precipitation can not adhere to, it will occur in conventional cover means.Float element 38 also possibly taked polyhedral form, shown in numeral 40 among Fig. 1.

In the centralized arrangement position, and more specifically, at the place, crosspoint of each independent interlayer 20 to 26, lid 10 comprises bonding pad 42.Bonding pad 42 comprises connector 44, is being ring shown in the example, and it can be used to settle liner 10, and wherein liner 10 is positioned at the upper surface of the liquid level that will be capped, and the Fig. 3 that will discuss like hereinafter is to shown in Fig. 5.

Advantageously, through in the lid centre position bonding pad 42 being provided, lid 10 is handled more simply.Middle section 42 is actual to be the barycenter of lid 10.Likewise, when lid 10 was picked up, whole unit folded into downward hanging position (downward draped position), like an in order unified unit.Lid 10 comprises that the fact of independent interlayer 20 to 26 also helps simple manipulation.Independent interlayer 20 to 26 is considered and is kept spheroid 38 more uniformly.This is a significant difference with respect to the system that does not merge independent interlayerization.Do not have interlayer, when lid is taken away in order to reorientate, float element 38 or spheroid will have with reverse sphere (inverted bulb shape) form and gather all-in-one-piece trend, opposite with the unit that independently dangles (individual draped unit).When motion, along with the situation of upset spheroid type,,, the spheroid of lumped mass will be provided at local relatively point having difference aspect the control lid 10, it can oppress flexible material prematurely, causes too early wearing and tearing or damaged.In addition, it will be understood by a person skilled in the art that under the strong wind condition, upset spheroid profile has presented the very big surface area that contacts with wind, therefore moving quite has challenge.These shortcomings are able to avoid through interlayerization is provided, and interlayerization makes the quality of buoyancy aid 38 distribute with more effective mode, to avoid the high stress point of

flexible material

12 and 14.

Have been found that with regard to

flexible material

12,14 and sew up with regard to 18 that the material that can make lid can comprise HDPE.Other suitable examples comprise polypropylene, high impact polystyrene (HIPS) and polyethylene.These materials are suitable, because they have the fact of the characteristic that is suitable for cap structure, promptly proportion is less than water.The ability that keeps ultra-violet stabilizer to prevent owing to expose premature oxidation in the sun, and the durability under the service condition of temperature from high temperature to subfreezing temperature fluctuation.

Also find, be used to have the

flexible material

12 and 14 of the lid 10 of float element 38 through use, freezing precipiation has no remains on the tendency on flexible material or the spheroid 38.This is because precipitation is transferred to spheroid 38 effectively through porous material 12 and 14.Because spheroid obviously has circular surface, the trend that tumbles simply from the surface of spheroid 38 is arranged for precipitation.As shown in fig. 1, float element or spheroid 38 can also be replaced by polygonal outer shape 40.About precipitation of tumbling etc., polygonal outer shape 40 also has similar spherical attribute.

Turn to Fig. 2, be depicted as another embodiment of the present invention, wherein cap structure 10 illustrates with the form of overall rectangle, and is different with the ring form shown in Fig. 1.

Turn to Fig. 3, be depicted as be positioned at liquid housing container 46, like the perspective view of the lid 10 that is placed in original position.

About Fig. 4, the rectangular in form of lid 10 is illustrated, as is placed in the pond upper surface, and is whole by numeral 48 expressions.

Fig. 5 shows an embodiment, and wherein lid 10 has asymmetric profile, is used to cover pond 50.

About Fig. 6, shown is another variation of the general construction of Fig. 1.

As described, the buoyancy aid 38 among this embodiment shows the spheroid of two different sizes.Although single diameter sphere has obvious practicability aspect the heat-insulating property of lid 10 increasing, provide second or the spheroid of a plurality of different sizes also have tangible advantage.This advantage realizes through the following fact, when promptly single diameter sphere is used, and gapped volume between spheroid.Through the spheroid of different size is provided, interstitial volume can be filled, and therefore the surface with bigger heat-insulating property is provided.This is that the spheroid of different size is filled the whole zone that will be capped with gap owing to there is not the fact of open area.

Those skilled in the art should know that maximum spheroid filling (maximum spherical packing) can obtain through using size distribution, and a large amount of sphere size are wherein arranged, and has given distribution.This provides the spheroid filling maximum possible degree, and the interstitial volume of minimum.According to the present invention, for the buoyancy aid under the spheroid geometry situation, expection lid 10 can comprise a plurality of diameters.About the polyhedron geometry, similarly situation also exists; According to polyhedral concrete geometry, the polyhedron of different size can promote space contribution (interstitial contribution).

Noted before like this paper, the stitching 18 between interlayer 20 to 26 can be continuous or discontinuous.In the latter case, it should be understood that to sew up is enough to keep buoyancy aid 38, makes them can not move to another from an interlayer and goes.

Aspect the material of

flexible layer

12 and 14 manufacturings, spendable suitable material has been discussed.Aspect porous, any suitable net or mesh size all possibly adopted, as long as enough form required size, are arranged in each independent interlayer 20 to 26 to keep buoyancy aid 38.

Industrial applicibility
