gas storage tank

7, and 1 inside scalable splint 9 that is equipped with of landing stage that every through-hole 8 corresponds.

Preferably, the retractable clamping plate 9 is installed in the middle of the movable plate 10, one end of the movable plate 10 is provided with an internal threaded hole in threaded fit with the screw 11, a vertical bevel gear 12 is fixedly sleeved on the surface of the screw 11, the vertical bevel gear 12 is meshed with a horizontal bevel gear 13, the horizontal bevel gear 13 is connected with one end of a rotating rod 15 through a rotating shaft 14 which is vertically arranged, and the other end of the rotating rod 15 is hinged with a rotating handle 16. When the handle 16 is rotated, the rotating rod 15 can be driven to rotate, so that the rotating shaft 14 rotates, the horizontal bevel gear 13 rotates, the vertical bevel gear 12 is driven to rotate, and finally the screw 11 rotates, and due to the threaded fit between the screw 11 and the moving plate 10, in the embodiment, the thread directions of the internal thread holes of the two moving plates 10 are different, so that the moving directions of the two moving plates 10 are opposite, or the moving directions are opposite.

Preferably, the two ends of the screw rod 11 are limited on the inner side wall of the pontoon 1 through the first bearing 17, and the rotating shaft 14 is limited on the pontoon deck 2 through the second bearing 18.

Preferably, the other end of the moving plate 10 is provided with a guide hole penetrating through the guide rod 19, and two ends of the guide rod 19 are fixed on the inner side wall of the pontoon 1. The movement of the moving plate 10 can be limited and guided by the guide rod 19.

Preferably, the retractable clamping plate 9 is of a cambered plate-shaped structure. After the cambered surface platy structure is designed, the shape of the cambered surface platy structure is matched with the shape of the space division liquefied gas storage tank 7, and the cambered surface can be tightly attached to the surface of the space division liquefied gas storage tank 7, so that the space division liquefied gas storage tank 7 can be clamped tightly, and the shaking is prevented.

Preferably, the retractable clamping plate 9 is connected to one side of a bearing plate 21 through a connecting rod 20, and the other side of the bearing plate 21 is connected to the surface of the moving plate 10 through a compression spring 22. After the design like this, can make scalable splint 9 compress tightly space division liquefied gas storage tank 7 through compression spring 22's elasticity effect, and compression spring 22 also plays the cushioning effect simultaneously, prevents that scalable splint 9 from pressing the deformation with space division liquefied gas storage tank 7.

Preferably, a floating bridge 24 is also arranged between the shoreline 6 and the pontoon 1. The floating bridge 24 is convenient for people to go to the wharf boat 1 for specific operation.

The working principle of the embodiment is as follows:

on the pontoon 1, a plurality of air separation liquefied gas storage tanks 7 can be arranged at the same time, each air separation liquefied gas storage tank 7 can store gas such as nitrogen, oxygen, argon, hydrogen, carbon dioxide and the like, the storage tank is provided with an inner container and an outer container, the inner container stores the air separation liquefied gas, the outer container bears the load, and a heat insulating material is filled between the inner container and the outer container; the size of the volume of each storage tank is designed according to a certain proportion, and the proportion is determined according to the proportion of single gas in the air and by considering the change of the proportion of various liquefied gases after liquefaction, different evaporation loss rates of different air separation liquefied gases after long-distance transportation and other factors; each air separation liquefied gas storage tank 7 is provided with an independent liquid cargo pump which can independently load and unload the air separation liquefied gas;

when different space division liquefied gas storage tanks 7 penetrate through the through holes 8 and are placed on the cabin bottom plate 3, the rotating handle 16 can be rotated, the rotating rod 15 can be driven to rotate, the rotating shaft 14 is driven to rotate, the transverse bevel gear 13 is driven to rotate, the vertical bevel gear 12 is driven to rotate, and finally the screw rod 11 is driven to rotate; the clamping action of the two telescopic splints 9 can ensure that the air separation liquefied gas storage tank 7 is not easy to shake, thus ensuring safety;

when in use, the pontoon 1 is parked near the shore line 6, is fixedly connected with the shore line 6 through the upstream cable 4 and the downstream cable 5, and pumps the air separation liquefied gas into the corresponding air separation liquefied gas storage tank 7 through the cryogenic pump; when in sale, the cryogenic pump pumps the liquefied gas for air separation into the corresponding tanker on the shore.

This patent is through cooperation ship transportation to the sale radius of empty liquefied gas that divides has been increased. The cost of the liquefied gas for air separation is 0.7-1 yuan/t.km, the maximum economic transport radius is 300 km, the cost of water transportation and loading and unloading is 0.1-0.15/t.km, and the storage cost is 30-35 yuan/t; if the water transport distance is x km, then the air separation liquefied gas is stored and sold in the range of 50 km in a centralized way in the air separation process, and the transportation cost is calculated according to the maximum economic transportation radius of 300 km for land transport, the equation is (0.7-1 yuan/t.km) × 300 km = x (0.1-0.15/t.km) + (30-35 yuan/t) + (0.7-1 yuan/t.km) × 50 km, and x = 1433-1450 km; therefore, by matching with ship transportation, the liquefied gas is sold in the range of 50 km of the concentrated storage pontoon for the air separation liquefied gas, and the sale radius can be increased by more than 1000 km compared with the air separation liquefied gas transported by land; in addition, the landing stage for the concentrated storage of the liquefied gas in the air separation mode occupies a smaller land area than a shore-type concentrated storage station for the liquefied gas in the air separation mode.

The above embodiments are merely preferred technical solutions of the present invention, and should not be considered as limitations of the present invention, and the features in the embodiments and the examples in the present application may be arbitrarily combined with each other without conflict. The protection scope of the present invention shall be defined by the claims and the technical solutions described in the claims, including the technical features of the equivalent alternatives as the protection scope. Namely, equivalent alterations and modifications within the scope of the invention are also within the scope of the invention.
