Description

The automatically tackling blockage water device of freight container

The utility model relates to a kind of automatically tackling blockage water device that is used for cargo-type container or other cargo cabin.

As everyone knows, when cargo-type container or cargo cabin are placed on the seagoing vessel deck in transportation, on lumpy sea, have a large amount of seawater and swarm the deck, the bottom of freight container will be immersed in the seawater like this, and seawater or inrush of air internal container then can make the rotten or damage of the article in the case.

For this reason, the existing automatic bailer that is used for cargo-type container of prior art, as No. the 97122647.4th, Chinese patent application and the US Patent of submitting on November 26th, 1,997 5,201,340, utilize these devices the ponding in freight container or other cargo cabin can be discharged really, and when outside when ponding is arranged, can prevent that sealing pours in down a chimney in the cartonning by this device outside case, and because these devices during normal use are in closed state, therefore, particularly when in thermal container, using, can also completely cut off in the case, the circulation of outer gas, and the normal operation of assurance insulation can.

Yet still there are following problems in these devices during actual the use.For example, in the device that Chinese patent application 97122647.4 discloses, number of components is many, keeps in repair and cost is increased and be not easy to; This device is divided into upper and lower two chambers simultaneously, and the chamber internal volume is little, easily makes impeded drainage, is not easy to cleaning.In addition owing to be to locate bead by guide pin bushing, so increased the complexity of production technology, easily make again and produce the stifled phenomenon of card between sealing bead and the guide pin bushing, thereby also can cause impeded drainage or the circulation of the inside and outside gas of fully sheathed case well, especially when the impurity that produces in the case enters freeing arrangement with current, easier generation is stopped up or phenomenon that can not confining gas.

In view of the above-mentioned defective of prior art, the purpose of this utility model provide a kind of simple in structure, draining is smooth and easy and water blockoff and the effective freight container automatically tackling blockage water device of confining gas.

For achieving the above object, the freight container automatically tackling blockage water device that the utility model proposes comprises following structure, a tubular housing, and described cavity upper opening, the upper end inner tubal wall has screw thread, and chamber is built-in with a georama; Be characterized in that a cover plate is twisted and to be combined on the described cavity inner tubal wall and to constitute a chamber with cavity, described cavity bottom has a V-arrangement through hole, also has the V-arrangement through hole on the described cover plate.

Further, in above-mentioned automatically tackling blockage water device, the cover plate top also is provided with a filtering cover, and described filtering cover is also twisted and is combined on the cavity.

Compared with prior art, automatically tackling blockage water device of the present utility model has only a chamber, thus simple in structure, low cost of manufacture, and can make full use of chamber and make draining smooth and easy, the difficult obstruction; In addition, the utility model has adopted upper and lower V-shaped groove structure, and georama is fallen in the groove reposefully, plays sealing process; Simultaneously, in the utility model because simple in structure, easy accessibility, even after long-term use is contaminated, as long as split out the coverplate parts of this device, clean inner cavity easily just.

Below in conjunction with accompanying drawing, an embodiment is described to automatically tackling blockage water device of the present utility model, wherein:

Fig. 1 is the section-drawing of an embodiment of the utility model automatically tackling blockage water device.

As can be seen from Fig. 1, automatically tackling blockage water device of the present utility model comprises a tubular housing 1, and this cavity top is opening, and its inner tubal wall has screw thread, and cavity is built-in with a georama 2 simultaneously; To be cover plates 3 by outside thread twist characteristics of the present utility model is incorporated on the cavity inner tubal wall screw thread and constitutes a chamber with cavity, and a V-arrangement through hole 11 is arranged at cavity 1 bottom, has a V-arrangement through hole 31 on this cover plate 3.

During use, the georama 2 in the utility model automatically tackling blockage water device chamber owing to the deadweight drop in the V-arrangement through hole 11 of cavity bottom, even and under the state of jolting georama 2 also can turn back to rapidly in the V-arrangement through hole 11.Like this, the georamas 2 that drop in the V-arrangement through hole 11 make through hole 11 sealings, and the circulation that has completely cut off the inside and outside gas of case, and are specially adapted to cargo loading system such as insulation can.When in the case ponding being arranged, ponding flows into chamber (at cavity top plan in the utility model and the complete welded seal in case tank top plate ground as prior art by the V-arrangement through hole on the cover plate 3 31, also can adopt bonding, riveted joint mode to seal), when ponding reaches a certain amount of, georama 2 floats under buoyancy, and ponding is discharged to outside the case by the V-arrangement through hole 11 of cavity bottom; When having ponding to produce outside the case, georama 2 is subjected to the buoyancy of water effect of case apposition and floats, cavity through hole 11 is opened, the outer ponding of case enters in the chamber, when the ponding in the chamber reaches a certain amount of, georama 2 is headed in the V-arrangement through hole 31 of cover plate 3 and is blocked this through hole, and ponding just can not flow in the freight container like this.

In utility model, in order to prevent that foreign material bigger in the case from entering cavity and stopping up V-shape hole, thereby further improve drainage effect or prevent that ball can not stably be arranged in through hole, above cover plate 3, also be fixed with a filtering cover 4, be provided with many small through hole 41 on this filtering cover 4, ponding can therefrom flow through in the case like this, blocks impurity in the case simultaneously.In the present embodiment, this filtering cover 4 is to twist by the screw thread on it to be combined in the cavity and to be positioned at cover plate 3 tops, twist close after, the top plan of filtering cover is concordant substantially with the cavity top plan.

From above recognizing; automatically tackling blockage water device of the present utility model not only can be discharged the interior ponding of case automatically but also can be blocked the outer ponding of case; the circulation that also can completely cut off the inside and outside gas of case simultaneously; anti-leak-stopping heat (cold) there is good effect, especially acts on significantly prevent that some special protection gas is lost to outside the case in case.

Abovely design of the present utility model, characteristics and effect are described, yet should be appreciated that this embodiment only is used for casehistory the utility model according to an embodiment, and to the unqualified effect of interest field of the present utility model; Obviously those of ordinary skill in the art can also carry out multiple change to this embodiment in design scope of the present utility model, and these changes also should fall into scope of the present utility model.
