Description

The present invention enables a tank container containing liquefied hydrogen (liquid hydrogen) to be a fixed type that is directly placed while being mobile, and serves as a liquefied hydrogen storage tank, and the tank container is It relates to a liquefied hydrogen transport system that can be separated and loaded by lifting operation and can be done immediately after placing it directly, can be downsized, and can be expected to meet a wide range of demands while keeping the price low.

Specifically, a tank container equipped with a hydrogen tank that can be filled with liquefied hydrogen is equipped with lifting jacks on the front and rear sides, and the jacks move the tank container up and down to load and separate it from the truck bed. efficiently, efficiently circulating between the hydrogen storage and the hydrogen station or between the hydrogen storage and the power plant, in particular, the tank container can be directly placed, and the liquefied hydrogen loading or discharging work It relates to a liquefied hydrogen transport system that can efficiently

In relation to liquefied hydrogen, there are on-site and off-site. The on-site type is configured to produce new liquefied hydrogen at a hydrogen station, and is a rare type in Japan. The off-site type is a general type of hydrogen station that currently has a liquefied hydrogen storage tank (liquefied hydrogen storage tank) but does not produce liquefied hydrogen.

At present, most of the hydrogen fuel supplied from a liquefied hydrogen storage to a general hydrogen station is transported in a state of high pressure gas by a hydrogen gas cartel trailer (not shown). In this regard, as described in Patent Document 1, the amount that can be transported by a hydrogen gas cardle trailer is considerably small in Patent Document 1 per trailer. At present, the ratio of fuel cell vehicles (FCV vehicles) is quite small, so even this one transport volume is sufficient.

There is also an example of transporting liquefied hydrogen by tank truck, but as the conventional technology on the right side of FIG. When it comes to large petroleum tank trucks, about 16 kl to about 20 kl are conveyed. Although it is possible to make a small turn to a medium-sized petroleum tank truck, it must be left at the hydrogen station where it arrives, along with the vehicle, which inevitably reduces the transportation efficiency. When it comes to large petroleum tank trucks, it is difficult to make small turns, and it is necessary to keep them at the hydrogen station for the desired time, making efficient transportation difficult.

In addition, as shown in FIG. 34, in major transportation companies, etc., the cargo is arranged on a platform from the viewpoint of physical distribution efficiency. It was common to install In this case, the height of the center of gravity Mc of the delivery container is positioned high. In such a physical distribution relationship, even if a hydrogen tank or a hydrogen container is transported at a hydrogen station, it is expected that the hydrogen tank or hydrogen container will be installed on the frame a.

Patent Literature 2 describes that an industrial gas is transported (conveyed) while a tank container is loaded on a dedicated container transport vehicle. In particular, only FIG. 8 describes transportation by truck, but all descriptions in the specification describe it as a transport vehicle 20 dedicated to containers. On the drawings, it is described as a towed vehicle as an articulated vehicle. Specifically, it is the trailer itself, the tank container is a trailer as a towed vehicle on the side to be towed, and the vehicle that tows the trailer is called a tractor.

In FIG. 8(b) of Patent Document 2, a container is unloaded, but there is absolutely no description of how the unloading is performed. A plurality of wheels are provided at the bottom of the trailer, and it is difficult to imagine unloading from the state with wheels attached, but there is no description of this point at all. Such trailer-type tank container transportation (conveyance) is considered to have taken into account transportation efficiency, which is physical distribution.

In the current situation, tank trucks filled with liquefied hydrogen (liquid hydrogen) are becoming larger and unsuitable for narrow spaces. was forced to soar. In particular, in a hydrogen station, stationing a plurality of the tank trucks inevitably increases the cost of facilities as well as the space.

For this reason, when transporting from a hydrogen storage station to a hydrogen station, it is possible to transport a relatively large amount of transport, and the operation and transport conditions can be comfortable, and only the hydrogen container for storage can be installed separately, and the cost is low. There is a demand for a transport system at an affordable price. Furthermore, measures for expensive liquefied hydrogen storage tanks (liquefied hydrogen storage tanks) at hydrogen stations are also desired.

Further, Patent Document 3 discloses an invention of a ferry-type cargo house in which a lifting jack or an outrigger is attached to a container (cabinet) that can be loaded on the bed of a truck. Concretely, the physical distribution transport is performed by loading and unloading the cargo at the platform 17 (train or ship) through the lifting drive of the lifting jack.

It is a transport system that passes through the 17 platforms, and the container is installed at the platform with the lifting part of the lifting jack extending downward, and the center of gravity Mc of the container is always high, For the purpose of increasing physical distribution efficiency, there is no description of lowering the container to the ground.

Currently, swap body containers are becoming popular as a container transport system in which arbitrary containers and truck beds are separated and loaded, and great expectations are placed on this transport system. However, this container basically has a stand a with legs b (see FIG. 34), and the current situation is that the container is not placed directly on the ground from the viewpoint of physical distribution efficiency.

Japanese Patent Application Laid-Open No. 2021-139375 JP 2015-155717 A Chinese Patent Application Publication No. 110422499

Under such circumstances, the problem (technical problem or purpose, etc.) to be solved by the present invention is that tank trucks or trailers that can be filled with liquefied hydrogen (liquid hydrogen) are becoming larger and unsuitable for narrow spaces. Only the container with a hydrogen tank could not be separated (unloaded) and was inefficient. As a result, the container with hydrogen tank can be separated from the cargo bed fixed to the truck, and the container with hydrogen tank can be transported more efficiently. Realization of a liquefied hydrogen transport system capable of

Therefore, as a result of earnest research to solve the above problems, the inventors have developed a tank container having a rectangular parallelepiped frame-shaped container body and a hydrogen tank that can be filled with liquefied hydrogen. A liquefied hydrogen transport system using a truck as only one vehicle fixed to the rear of the cab as a loading platform for loading and unloading the entire tank container with a jack,
The tank container and the loading platform can be loaded using only the front and rear jacks on the tank container placed directly on the ground, and the cargo can be unloaded using the jacks attached to the front and rear of the tank container. The loading/unloading structure has a slide member that expands outward in the width direction at the front end of the container body by hydraulic drive, and also up and down. Along with the two telescopic front composite jacks, the two rear jacks, which are arranged on both sides in the width direction at the rear end of the container body and telescopic only up and down, are each hydraulically driven,
In the truck with the tank container that can be transported between the hydrogen storage location and the hydrogen station or between the hydrogen storage location and the power plant, the liquefied hydrogen is immediately loaded into the directly placed tank container after arriving at the desired location. Alternatively, the above problem is solved by providing a liquefied hydrogen transport system characterized in that the discharging operation can be performed in one step.

In the liquefied hydrogen transport system according to claim 1, the invention of claim 2 is configured such that the tank container in which the hydrogen tank is fully filled with liquefied hydrogen in the hydrogen storage station is a full tank container, and the liquefied hydrogen is empty. Each of the tank containers that have been filled is called an empty tank container,
After transporting the full-tank container at the hydrogen storage station to one of the plurality of desired hydrogen stations or power plants by the truck loaded via the plurality of jacks, the full-tank container is transported at the location. Unloaded and placed directly on the ground with only the full tank container,
A liquefied hydrogen transfer system characterized in that the empty tank container that has already been directly placed at the location is loaded on the bed of the truck that has just been separated and is transferred to the hydrogen storage station. By doing so, the above problem was solved.

The invention of claim 3 is the liquefied hydrogen transfer system according to claim 1 or 2, characterized in that the hydrogen station is not provided with a liquefied hydrogen storage tank. Thus, the above problems were solved. According to the invention of claim 4, in the liquefied hydrogen transport system of claim 1 or 2, hydraulic pressure generators for both the front side jacks and both the rear side jacks are provided in the tank container. The above problem was solved by adopting a liquefied hydrogen transport system that

In the liquefied hydrogen transport system according to claim 1 or 2, the invention of claim 5 is provided with hydraulic pressure generators for both the front side jacks and both the rear side jacks on the truck, and the truck and the tank container are connected to each other. The liquefied hydrogen transfer system is characterized in that both the front side jacks and both the rear side jacks of the tank container are drivable only when the hydraulic circuits are connected. Settled. In the liquefied hydrogen transport system according to claim 1 or 2, the tank container directly placed on the desired place is placed on the second floor via overlapping auxiliary pieces at the four corners. Alternatively, the above problem is solved by providing a liquefied hydrogen transport system characterized in that it is constructed so that it can be stacked on three or more floors.

In the invention of claim 1, the tank container containing liquefied hydrogen (liquid hydrogen) can be a fixed type that is directly placed while being mobile, and also serves as a liquefied hydrogen storage tank. It has an effect that many demands can be expected. Specifically, the hydrogen storage station and the hydrogen station, the hydrogen storage station and the power plant, or the hydrogen storage station and other hydrogen supply stations are transported by tank container-loaded trucks, and the ground is placed at each location. The tank container alone can be immediately placed directly on the tank by the lifting action of both the front side composite jacks and both the rear side jacks, and the tank container can be stored as it is, and can serve as a liquefied hydrogen storage tank. . Furthermore, instead of the tank container separated at the site, another tank container can be immediately loaded on the truck to provide a very good liquefied hydrogen transportation system that can be carried out very easily and quickly at the site. be. Furthermore, at a desired location, the tank container can be directly placed to lower the center of gravity and be stably and safely installed, providing an effect different from the physical distribution method.

In addition, in the invention of claim 1, in particular, when the liquefied hydrogen is loaded into and discharged from the tank container immediately after the tank container is placed directly, the work can be done in one step without a chair or a step. produce the greatest possible effect. In addition, since both front side composite jacks exist via the slide member that slides outward in the width direction at the front end of the tank container, when the tank container is loaded on a truck, the tank container The space between the adjacent jacks only at the front side of is widened to prevent them from coming into contact with the bed of the truck. In addition, the widening work of both front composite jacks is performed manually and can be provided at a minimum cost. In particular, liquefied hydrogen can be efficiently transported from a hydrogen storage station to a hydrogen station or power plant.

As shown on the right side of FIG. 30, in the prior art, liquefied hydrogen tanks were transported between hydrogen storage stations or hydrogen stations using tank trucks or trailers. Was. This was to improve the efficiency of distribution and increase the operating rate. When installing at a desired location, the center of gravity of the tank truck or trailer is high, and the work of loading or discharging the liquefied hydrogen requires the use of a chair or a step, which is inconvenient for efficient work. However, in the invention of claim 1, as shown on the left side of FIG. There is a unique advantage of being able to load or unload liquefied hydrogen in one step without using a chair or step (dynamic configuration). At the same time, since the center of gravity is lowered by direct placement, stable installation can be achieved, and safety and security can be provided even with hazardous materials.

Moreover, in the invention of claim 2, a very efficient transport system can be provided between the hydrogen storage station and the hydrogen station or power plant. Furthermore, there is the advantage that full and empty tank containers can be transported between the hydrogen reservoir and the hydrogen station or between the hydrogen reservoir and the power plant with maximum efficiency. In the invention of claim 3, the hydrogen station is configured without a liquefied hydrogen storage tank, and the hydrogen station has a configuration in which the tank container of the present invention replaces the liquefied hydrogen storage tank. , the amount of capital investment for the hydrogen station can be reduced, and it can greatly contribute to the spread of hydrogen stations.

According to the fourth aspect of the invention, the hydraulic pressure generators for both the front side composite jacks and both the rear side jacks are provided in the tank container. There are advantages that can be In the invention of claim 5, the hydraulic pressure generators for both the front side composite jacks and both the rear side jacks are provided on the truck, and the tank container is operated only when the hydraulic circuits of the truck and the tank container are connected. Since both the front composite jacks and both the rear jacks are drivable, operators of hydrogen stations, etc. can deploy the tank container without a hydraulic pressure generator. It can be a relatively inexpensive equipment investment. The operation of raising and lowering the tank container is performed by the driver of the truck, and the person in charge who owns the tank container can easily perform the operation.

In the invention of claim 6, the tank containers can be stacked (stacked) on each other at a desired location such as a hydrogen storage station, a hydrogen station, or a power plant, so that the tank containers can be stacked on the second floor, the third floor, or more, thereby further saving space. can act as a hydrogen reservoir. In this case, the ground part is of course made of concrete and is hard and excellent in strength.

In this specification, the term simply "jack" is a generic term that includes front side compound jacks or rear side jacks, both of which are important components. Claim 1 describes two front composite jacks and two rear jacks, but hereinafter, both front composite jacks and both rear jacks are described. have the same or equivalent semantic content.

An embodiment of the hydrogen transport system of the present invention will be described below with reference to the drawings. The main components of the present invention are a tank container A and a truck B (see FIGS. 1, 2, 3, 4 and 5). The tank container A has a rectangular parallelepiped frame-shaped container body 1 provided with two unique front composite jacks 2 and 2 and two rear jacks 3 and 3 . Inside the tank container A, a hydrogen tank 4 filled with liquefied hydrogen (liquid hydrogen) is provided. The truck B has a power unit (not shown) and a loading platform 6 fixed to the rear of the driver's cab 5, and is constructed so that the tank container A can be loaded and separated on the loading platform 6. (see Figures 5, 7 and 8).

The tank container A can be loaded and separated from the cargo bed 6 of the truck B by lifting and lowering the hydrogen tank 4 inside the container body 1, the front composite jacks 2 and 2, and the rear jacks 3 and 3. (See FIGS. 1 to 3, 5, 7 and 8). A truck B loaded with a full or empty tank container A filled with liquefied hydrogen is transported to a desired hydrogen storage location C and a plurality of desired hydrogen stations D (first route) or the hydrogen storage location C and a power plant D ( 2nd route) or between the hydrogen storage station C and the other hydrogen supply station P 3rd route), and the full tank container A is directly placed at the desired hydrogen station or power plant D , an empty tank container A directly placed at the location is loaded onto the truck B, and the liquefied hydrogen transport system is carried out once or repeatedly (see FIGS. 1 and 3). It should be noted that the first to third routes are in a parallel relationship, not in the order of which is first, second, and third.

Hydrogen supply destinations include the hydrogen station D, the power plant E, and other hydrogen supply stations P such as major transportation companies and local governments. As shown in FIG. 1, the hydrogen station D does not have a liquefied hydrogen storage tank 91 (also referred to as a liquid hydrogen storage tank), and has a vaporizer 92, a compressor 93, and a pressure accumulator unit 94 (simply referred to as a pressure accumulator or Also called a hydrogen pressure accumulator) and a dispenser 95 are provided. Although a precooler exists, it is omitted. The route between the other hydrogen supply station P and the hydrogen storage station C is sometimes called a third route.

Further, as shown in FIG. 33, the currently existing hydrogen station, that is, the current hydrogen station Dex, is provided with a liquefied hydrogen storage tank 91 of a predetermined amount [generally about 300 kiloliters (kl)]. ing. Often more or less than this. The hydrogen storage station C is equipped with a large-capacity (currently about 10,000 kl) liquefied hydrogen storage tank 91, a vaporizer 92, and a compressor 93. 1, 2, 3, 10, 24 and 25, the evaporator 92 and the compressor 93 are omitted because the purpose of the present invention is to transport.

As shown in FIG. 3, the power plant E does not have a liquefied hydrogen storage tank 91 (also referred to as a liquefied hydrogen storage tank). A gas turbine 98 and a generator 99 are provided, and the generator 99 is configured to output electric power. In addition, in the case of the current power plant Eex, as shown in FIG. 25, a liquefied hydrogen storage tank 91 with a large capacity [currently about 10,000 kl to about 300 kl] is provided. This is the current situation with many things.

A truck B loaded (loaded) with the full tank container A is transported to a desired or designated location of the hydrogen station D, where the tank container A is separated from the loading platform 6 and placed on the ground surface G1. 1, 3, 10, 24 and 25, and the left side of FIG. 7(A). The direct placement basically means that the bottom surface of the tank container A is placed in direct contact with the ground portion G1 (see FIG. 32). Here, the ground portion G1 is a portion as a concrete pedestal having a predetermined thickness (approximately 30 cm) provided on the ground or the ground G, and is several times higher than the ground or the ground G. Although it is formed higher by cm, it may be of the same height. In addition, the ground portion G1 also includes a place where an iron plate or a wooden plate is laid.

Regarding the ground portion G1, when a slight gap (about several centimeters, about 5 cm) is provided in the ground portion G1, or when a spacer member 99 such as a strong pedestal having a height h of about several centimeters is interposed. However (see FIG. 16), it is included in the category of direct placement. In this way, direct installation and storage (see FIG. 32) lowers the center of gravity Mc of the tank container A, making it particularly difficult to tip over and stabilizing it. A can be stored safely and can be reassured. Direct placement is the basic content for the tank container A, but it is particularly effective for the full tank container A1, and the same is true for the empty tank container A0. In other words, direct placement can be stabilized and made safe regardless of whether the tank is full or empty.

Furthermore, by directly placing the tank container A, the work can be performed in one step. Specifically, loading of liquefied hydrogen from the liquefied hydrogen storage tank 91 to the tank container A, from the tank container A to the hydrogen station D or power plant E, and further within the facilities of the hydrogen supply station P It is possible to do the work of discharging liquefied hydrogen to the equipment and equipment in the factory without using a chair or a step stool.

As shown in FIG. 30, the fact that such a one-step operation can be performed can be said to be "dynamic configuration". As described above, the liquefied hydrogen tank container A can be hydraulically driven and jacked down for direct storage (low center of gravity Mc). It is an organic and effective effect in collaboration with work. In addition, the fact that the liquefied hydrogen tank container A can be stored directly is completely different from the conventional gasoline storage, and is required to be installed on the ground part G1 (High Pressure Gas Storage Law, etc.). For example, a well-ventilated location on the ground is suitable.

Here, in the description of the present invention, the terms indicating the direction of the tank container A are shown in FIGS. It is used as shown in (B) and FIG. 5(A). Specifically, the X-axis direction of the front-rear direction refers to the longitudinal direction connecting the front and rear sides of the tank container A and the truck B, and the width direction refers to the tank container A and the truck B. Y-axis direction indicating the width of Further, the Z-axis direction, which is the vertical direction, refers to the direction indicating the height of the tank container A and the truck B. As shown in FIG. The X-axis, Y-axis, and Z-axis directions of the front-rear direction, the width direction, and the vertical direction are shown in the main drawings.

The number of reinforcing diagonal members 14, . In particular, the reinforcing member 15a on the ceiling surface may be omitted. This is in consideration of the removal of the hydrogen tank 4 .

As shown in FIGS. 4(A) and 4(B), the front end of the container body 1 expands and contracts vertically via sliding members 22, 22 that slide outward in the width direction (by hydraulic drive). Two front side compound jacks 2, 2 are provided. Specifically, a cylindrical fixing portion 23 is attached to the front side member 12d of the front end of the container body 1 (right side of FIG. 4A, see FIGS. 4B and 12A and 12B).

In FIGS. 6A and 6B, the left and right halves correspond to the front composite jacks 2, respectively. In particular, the slide member 22 of the front side composite jack 2 is configured to be slid by the hydraulic drive of the hydraulic pressure generating device 7 (see FIG. 6(C)).

In particular, a large force is applied to the cylindrical fixing portion 23, and the front member 12d is required to have a strong member structure. At the rear end of the container body 1 (left side in FIG. 4(A)), two rear jacks 3, 3 are fixed which are provided on both sides in the width direction and extend and contract vertically while being immovable in the width direction. there is Specifically, as shown in FIG. 4, the hydraulic jacks 31, 31 of the rear jacks 3, 3 are fixed to the rear members 13a, 13c at the rear end of the container body 1, respectively. are provided with cylinder portions 31a, 31a and piston portions 31b, 31b, and the piston portions 31b, 31b are configured to extend downward from the cylinder portions 31a, 31a.

Both the rear jacks 3, 3 and the closed front composite jacks 2, 2 are set at least in a range equal to or not exceeding both ends in the width direction of the cab 5 of the truck B [Fig. (C) and chain line in FIG. 15(A) and 15(B), the hydraulic jacks 21, 21 and the slide members 22, 22 at the tip are at least at the cab 5 of the truck B when the both front side composite jacks 2, 2 are retracted. , or not exceeding the width of the cab 5, and is set to fit inward in the width direction. At the same time, the width of the container body 1 is regulated to be equal to or less than the width of the cab 5 .

Specifically, when the slide members 22, 22 are closed, the width is often smaller than the width of the loading platform 6 (FIG. 15(A)). Even so, the width is always set to be equal to or within a range not exceeding the width of the cab 5 (FIG. 15(B)). That is, the front-side composite jacks 2, 2 are constructed so as not to protrude from the width of the cab 5 when stored.

When both front side composite jacks 2, 2 slide outward from the width direction of the container body 1 and protrude, the amount of sliding is within several tens of centimeters to about 1 m (Figs. 4(D) and 5). (C)]. With such a configuration, by widening the distance between the piston portions 21b, 21b of the hydraulic jacks 21, 21, as shown in FIGS. 21b, 21b can be hardly touched and easy to drive can be performed, and the separation and loading of the tank container A from the loading platform 6 can be performed safely and quickly. Further, when the sliding distance is increased further, as shown in FIGS. And it is necessary to design and manufacture as a member.

Furthermore, in order to increase the amount of sliding, as shown in FIGS. That is, the cylindrical fixing portions 23, 23 are double fixed to the front side member 12d at the front end of the tank container A, and sliding members 22, 22 (manually) are provided outward in opposite directions, respectively. ing. Hydraulic jacks 21 , 21 are attached to the outer ends of the slide members 22 , 22 . Due to the presence of the double slide members 22, 22 in this way, the distance between the piston portions 21b, 21b of the hydraulic jacks 21, 21 of the front side compound jacks 2, 2 is large (approximately 1.5 m or more). ), the loading platform 6 of the truck B can be easily and smoothly put into the tank container A, and excellent maneuverability and efficient transportation can be achieved.

Regarding the relationship between the tank container A and the truck B, when the tank container A is loaded (mounted) on the loading platform 6 of the truck B, the tank container A is placed on substantially the entire loading platform 6. In particular, only the rear jacks 3, 3 are attached so as to protrude from the rear end of the loading platform 6 (see FIG. 5(D)). Further, as shown in FIGS. 8, 12 and 13A, the tank container A is constructed so that it can be loaded onto the loading platform 6 of the truck B only from the front side of the tank container A. As shown in FIG. Also, as shown in FIGS. 7 and 11, the structure for separating and loading the tank container A is described.

When the slide member 22 of the front side composite jack 2 is housed (when contracted), and when the piston part 21b of the hydraulic jack 21 is housed (when contracted), the lower end surface of the piston part 21b; There is a gap α of several centimeters between the truck B and the upper surface of the loading platform 6 (see the right side of FIG. 4(D)), and the slide member 22 is slidable.

Further, even when the tank container A is placed directly on the ground portion G1, the clearance α between the ground portion G1 and the lower end surface of the piston portion 21b of the hydraulic jack 21 of the front side composite jack 2 is about several centimeters. It is configured to exist [see FIG. 4(E)]. Similarly, when the piston portion 31b of the hydraulic jack 31 of the rear jack 3 is accommodated (when contracted), a gap α is formed between the piston portion 31b and the lower end surface [FIGS. 8(B)]. Note that the gaps α between the front and rear positions of the tank container A in FIG. 4(E) placed directly on the ground portion G1 are the same, but may be slightly different.

[About hydrogen tank 4]
The hydrogen tank 4 is also manufactured into a large type, a medium-sized type, and a small (semi-medium-sized) type. The large type is configured as a vertical hydrogen tank 4A as shown in FIGS. 22, 23, 28 and 31(C) left side. In terms of size, it corresponds to the current large petroleum tank truck (16 kl to 20 kl) [see the right side of FIG. In the tank container A with the container body 1, the hydrogen specific gravity is 0.071, which is less than 1/10 of the gasoline specific gravity. It is a sensory image diagram of.

Moreover, as a medium-sized type, as shown in FIG. 5, it may be configured as the spherical hydrogen tank 4B. It corresponds to the current medium-sized tank truck (4 kl) [see the right side of FIG. Furthermore, the small type corresponds to the current small tank truck (2 kl) [see right side of FIG. 31(A)]. The small type hydrogen tank 4 is smaller in length and size than the above-described medium type (see FIG. 4), and the constituent members have the same configuration, so the description thereof is omitted.

As described above, various types of structures such as sizes and shapes have been developed and manufactured. It has a structure that can withstand transportation. In this manner, the hydrogen tank 4 is filled with liquefied hydrogen as required, and is configured to be stored and transported at appropriate temperature and humidity. Also, the lengthwise hydrogen tank 4A in FIG. 4 may be downsized to have a medium-sized configuration, or the spherical hydrogen tank 4B in FIG. In particular, as shown in FIGS. 4, 16 to 20, and 26 to 29, the vertically elongated hydrogen tank 4A has a lower loading/discharging port 42 on the lower rear portion thereof, and a lower loading port/discharge port 42 on the upper side thereof. , and upper loading/discharging ports 43 are provided at 44 manholes. The spherical hydrogen tank 4B of FIG. 5 is also provided with a lower loading port/discharging port 42 .

As shown in FIG. Further, as shown in FIG. 5, in the case of the spherical tank 4B, it is constructed so that it can stand upright on a circular seat 19a provided on the bottom surface of the spherical tank 4B. The spherical tank 4B is installed on a reinforcing plate 19b and supported by a plurality of supporting rods 19c around the spherical tank 4B.

[Regarding the locking structure between the tank container A and the loading platform 6]
A lock device is provided so that when the tank container A is loaded on the loading platform 6 of the truck B, it will not come off due to vibrations of the truck B or the like. Specifically, as shown in FIGS. 5(E), (F), and (G), locking members 61 are provided at four corners of the loading platform 6, and the locking members 61 correspond to the locking members 61. Locked members 17 are provided at the four corners of the bottom surface of the tank container A. As shown in FIG. As for the operation, as soon as the tank container A is loaded on the loading platform 6, the handle 61b is turned about 90 degrees so that the protrusion 61a of the locking member 61 enters the hole 17a of the member 17 to be locked. In this state, the tank container A is loaded on the loading platform 6 of the truck B and conveyed.

[About the hydraulic control mechanism]
The hydraulic control mechanism is a control mechanism for both the front composite jacks 2 and 2 and the rear jacks 3 and 3 . Concretely, as shown in FIG. 9, it is a lift control mechanism for each of the hydraulic jacks 21, 21 and 31, 31. As shown in FIG. It is configured to be drivable via a hydraulic circuit 74 with the driving force of the hydraulic pressure generator 7 .

As shown in FIG. 9, the hydraulic pressure generator 7 is provided with a motor 71 and a hydraulic pump 72 drivable. Each is connected so that it can be raised and lowered. In particular, both hydraulic jacks 21, 21 (both front side composite jacks 2, 2) and 31, 31 (both rear side jacks 3, 3) are controlled by known technology so that they can be lifted and lowered simultaneously (synchronized lifting). It is A relief valve 75 is also provided.

Specifically, in the hydraulic circuit having the hydraulic pressure generating device 7 shown in FIG. 9, the first switching valve 73A controls the width expansion of both the slide members 22, 22 of the front side composite jacks 2, 2. Both hydraulic jacks 21, 21 (both front side composite jacks 2, 2) and 31, 31 (both rear side jacks 3, 3) of both front side composite jacks 2, 2 are controlled by the second switching valve 73B. It is configured so that it can be raised and lowered at the same time (synchronized raising and lowering).

[Regarding the built-in type in the tank container A for the hydraulic pressure generator 7]
The hydraulic pressure generating device 7 is provided at a part (on the front end side or the rear end side) inside the tank container A, as shown in FIG. 8(B) on the left side of FIG. Hydraulic jacks 21, 21 of both front side composite jacks 2, 2 and both hydraulic jacks 31, 31 of both rear side jacks 3, 3 from the hydraulic pressure generator 7 are provided with the aforementioned hydraulic circuit 74. The piston portion 21b and the piston portion 31b are configured to be extendable and retractable.This built-in type is convenient for loading and separating the tank container A from the loading platform 6 of the truck B, and the work can be performed more quickly. is.

The operation of loading the tank container A onto the loading platform 6 of the truck B with the built-in hydraulic pressure generating device 7 (within the tank container A) will be described [see FIG. 8(A)].
First, the slide members 22, 22 of the both front side composite jacks 2, 2 of the tank container A are manually pulled out and stopped, and the hydraulic pressure generator 7 in the tank container A is driven to operate both front side composite jacks 2, 2. Both piston parts 21b, 21b of both hydraulic jacks 21, 21 of the jacks 2, 2 and both piston parts 31b, 31b of both rear side jacks 3, 3 are extended at the same time so that the lower ends of the legs are placed on the ground part G1, When the bottom surface of the tank container A is slightly higher than the upper surface of the loading platform 6 of the truck B, when a gap β is generated, the state in which each piston part is extended is maintained, and only the tank container A is kept standing.

Therefore, while taking the state shown in FIG. 13(A), the truck B is moved backward, and the loading platform 6 is positioned directly below the tank container A, and the truck B is stopped. Immediately after, each piston portion of the tank container A is contracted to complete the mounting of the tank container A on the loading platform 6 . This is the tank container A built-in type.

[Work situation in hydrogen station D or power plant E] [See left side of Fig. 7 (A)]
Separation of the tank container A from the truck B in the tank container A built-in type will be described as a specific example. First, when the full tank container A1 is transported to the hydrogen station D or the power plant E by truck B, the truck B is stopped at a predetermined position at this place, and the slide members 22 of the both front side composite jacks 2, 2 of the tank container A , 22 are manually pulled out and stopped. Then, by driving the hydraulic pressure generating device 7 in the tank container A, both piston portions 21b, 21b of both hydraulic jacks 21, 21 of both front side compound jacks 2, 2 and both piston portions of both rear side jacks 3, 3 The legs 31b, 31b are extended at the same time and the lower ends of the legs are put on the ground part G1.

Further, both piston portions 21b, 21b and both piston portions 31b, 31b of both rear side jacks 3, 3 are extended, and an appropriate gap β [about About several cm to about 10 cm: see the left side of FIG. After that, the hydraulic pressure generating device 7 is driven again to contract the respective piston portions of the full tank container A1, and only the full tank container A1 is directly placed on the ground portion G1 [see the lower left side of FIG. 7(A)]. ].

[Work situation in hydrogen station D or power plant E] [See right side of Fig. 7 (A)]
Next, in the same hydrogen station D or power plant E, an empty tank container A0 different from the full tank container A1 is directly placed. , 2 are manually pulled out and fixed on the loading platform 6 of the truck B. This detailed explanation is the same as the content explained in FIG. Although omitted, it is shown in the direction of the arrow on the right side of FIG. 7(A).

[Operation status in hydrogen storage station C] [See FIG. 7(B)]
After the empty tank container A0 is transported to the hydrogen storage station C, it is separated. This separation operation is shown in the left side view of FIG. This is the same as the operation [see the left side of FIG. 6A], and the explanation thereof is omitted.

In addition, another full-tank container A1, which has become full at the hydrogen storage station C, is loaded onto the same truck B's bed 6. As shown in FIG. This operation is the same as the operation of loading the empty tank container A0 on the loading platform 6 of the truck B [see the right side of FIG. 7(A)]. There is, and the explanation is omitted.

[Concerning the built-in type of the hydraulic generator 7 in the truck B] (see FIG. 12)
The hydraulic pressure generating device 7 is provided in a part of the inside of the truck B (on the driver's cab 5 side or on the rear end side of the cargo bed 6, which is behind the cab 5 in FIG. 12 in the embodiment).
The hydraulic configuration of the truck B built-in type will be described (see FIG. 12). In particular, when the hydraulic pressure generating device 7 is of the truck B built-in type, the couplings 76a and 76b and the hydraulic hose 74a and the hose winding portion 74b in the hydraulic circuit 74 are provided.

12, the hydraulic hose 74a in the hydraulic circuit 74 is required only for "the length of the loading platform 6+the height of the loading platform 6". This is possible with a known technique for the hose winding portion 74b that prevents entanglement, etc., and detailed drawings are omitted. With this built-in type, the loading and unloading of the tank container A at the hydrogen storage station C, the hydrogen station D and the power plant E takes some time and effort, but the cost of the tank container A can be particularly reduced.

Loading/separation of the tank container A on the loading platform 6 of the truck B in which the hydraulic pressure generating device 7 is built in the truck B will be described as a specific example.
[Operation status in hydrogen station D or power plant E] [See FIG. 11(A)]
The work of loading and separating the tank container A onto the loading platform 6 of the truck B is the same as that of the tank container A built-in type described above, but the difference is shown in FIGS. As shown, the hydraulic circuit is connected so that the loading platform 6 of the truck B and the tank container A are not separated.

To elaborate on this point, in FIG. 12, which is a built-in type of the hydraulic generator 7 in the truck B, it is provided on the rear side of the cab 5, and the hydraulic hose 74a as this hydraulic circuit is provided at an intermediate position of the cargo bed 6. A hydraulic coupling 76b is provided at the length corresponding to the height of the loading platform 6 and at the end via the hose winding portion 74b. The hydraulic coupling 76b can be hydraulically driven by physically connecting the hydraulic couplings 76a and 76b provided at the ends of the hydraulic circuit 74 of the four hydraulic jacks provided in the tank container A. It is configured.

That is, as shown in FIGS. 10 to 12, the difference is that the tank container A and the truck B are always operated while maintaining a physical connection state (by hydraulic coupling). In this way, by using the built-in type of the hydraulic generator 7 in the truck B, the truck B equipped with the tank container A containing the hydrogen tank circulates between the hydrogen storage station C and the hydrogen station D or the power plant E as appropriate. As a transport system (FIGS. 1 to 3), in particular, the operation is substantially the same as the tank container A built-in type (see FIG. 8), and is the same as the liquefied hydrogen transport system as the above-mentioned top concept or superordinate concept. and its explanation is omitted.

[Regarding the liquefied hydrogen transport system as the highest concept of the present invention]
First, as shown in FIGS. 1 to 3, regardless of whether the inside of the hydrogen tank 4 is empty or full, liquefied hydrogen is stored in the hydrogen storage station C and the hydrogen station D for the tank container A with the hydrogen tank 4. , power plant E, other hydrogen supply station P, the current hydrogen station Dex or the current power plant Eex while being transported and circulated to form a liquefied hydrogen transport system. Specifically, the tank container A loaded on the bed 6 of the truck B is transferred to the desired hydrogen storage station C, hydrogen station D or current hydrogen station Dex, power station E, current power station Eex, and other hydrogen supply station P. Both the front side composite jacks 2, 2 and both the rear side jacks 3, 3 are contracted at any place to separate the tank container A, and the tank container A is placed directly on the ground portion G1.

The hydrogen storage in the truck B loaded with the tank container A (empty) directly placed at any place via both the front side composite jacks 2, 2 and both the rear side jacks 3, 3 It is transported to any place such as Station C, Hydrogen Station D, or Power Station E, where only the tank container A is lifted by the lifting action of both the front side composite jacks 2, 2 and both the rear side jacks 3, 3. This is a liquefied hydrogen transport system that is separated and placed directly on the ground portion G1.

[Regarding liquefied hydrogen filling of tank container A]
First, the tank container A in which the hydrogen tank 4 is filled with liquefied hydrogen at the hydrogen storage station C is called a full tank container A1, and the tank container A in which the liquefied hydrogen is empty is called an empty tank container A0. name it. The terms of the full tank container A1 and the empty tank container A0 are the same for the liquefied hydrogen transport systems of the first embodiment and the second embodiment below, and the description thereof will be omitted.
In the hydrogen tank 4, the "empty" includes "empty" and "nearly empty".

[Regarding the basic liquefied hydrogen transport system of the present invention]
First, at the hydrogen storage station A, the full tank container A1 is loaded via both the front side composite jacks 2, 2 and both the rear side jacks 3, 3 on the truck B. to the hydrogen station D, power plant E, or other hydrogen supply station P (see Figure 1). Then, the full-tank container A1 is placed on the ground portion G1 of the hydrogen station D, power plant E, or other hydrogen supply station P that has arrived, by the lifting action of both the front side composite jacks 2 and both the rear side jacks 3. Then, only the full tank container A1 is separated and placed directly on the ground portion G1 (see FIGS. 1 to 3).

Next, the empty tank container A0 that has already been placed directly at the hydrogen station D, power plant E, or other hydrogen supply station P is loaded onto the same truck B that was previously separated, and in this state, the hydrogen Then, the empty tank container A0 is separated and placed directly on the ground portion G1 of the hydrogen storage site C. This is the liquefied hydrogen transport system.

FIG. 2 is a simplified diagram showing an example in which hydrogen is transported from a desired hydrogen storage station C in the Kanto area to one desired hydrogen station D among many. One desired hydrogen storage station C in FIG. 2 is connected to one desired hydrogen station D by an arrow. Specifically, the hydrogen storage C is connected to one hydrogen storage C in the Kanto area, and the hydrogen station D is connected to one hydrogen station D in the Kanto area. ing.

In the above description, the transport is performed only once, but it varies depending on the transport distance. In practice, it may circulate several times a day. In this case, the hydrogen storage location C is one location, and the hydrogen stations D are generally different hydrogen stations D respectively. In particular, even with a single truck B, the work involves repeatedly transporting a full-tank container A1 and an empty-tank container A0 separately. At Dex, power station E, the work only takes time for immediate separation and loading, so liquefied hydrogen can be transported very efficiently.

In the above explanation, the hydrogen storage station C, the hydrogen station D, or the current hydrogen station Dex are sequentially circulated, but in some cases, the same place may be transported multiple times, such as twice. There is also, but this is also included in the concept of circulation. Specifically, the full tank container A1 was loaded and headed to the hydrogen station D with the desired N (not shown in the drawing), but the hydrogen station D with the M (not shown in the drawing) was completely insufficient. Even when the empty tank container A0 at the location of the original hydrogen station D is loaded and brought back, there are various cases of circulatory relationship.

In this general concept embodiment, the hydrogen storage station C, the hydrogen station D, the power plant E, and the other hydrogen supply station P, only a full tank container A1 or an empty tank container A0 is placed on the ground portion G1 at that location. Can be placed upright. By directly placing the tank container A in this way, first, the center of gravity Mc is lowered, making it difficult for the tank container to overturn, and safe and secure storage is possible. In particular, it can ensure stability without overturning even in strong winds or earthquakes. Also, by directly placing the tank container A, the work can be done in one step.

Specifically, in this specification, the one-step means loading liquefied hydrogen into the tank container A, which is the main component of the present invention (from the liquefied hydrogen storage tank 91), From the hydrogen station D, the power plant E, and other hydrogen supply station P, it means that it is possible to do the discharge work of liquefied hydrogen to the equipment and equipment in the facilities of the hydrogen supply station P without a chair or a step. In particular, according to the present invention, there is an effect that the work can be performed in such a one-step manner.

In a specific bird's-eye view such as that shown in FIG. 2, one desired hydrogen storage station C (for example, Yokohama), which also exists in large numbers, is connected to one desired hydrogen storage station D (for example, some place in Tokyo). However, this is an example, and the full tank container A1 may be transported from one hydrogen storage station C in Yokohama to a hydrogen station D in Saitama. In this case also, the full tank container A1 can be placed directly.

From the hydrogen station D where the full tank container A1 is directly placed, the directly placed empty tank container A0 is picked up and transported. Specifically, the empty tank container A0 is loaded onto the loading platform 6 of the truck B via both front composite jacks 2 and both rear jacks 3 and transported to the hydrogen storage station C. Then, the empty tank container A0 is filled with liquefied hydrogen to prepare a full tank container A1. FIG. 2 shows an outline of the transport overview in consideration of the Keihin industrial area, Keiyo industrial area, Kashima coastal industrial area, etc. in Tokyo, Kanagawa Prefecture, and Chiba Prefecture, and can be applied to any application.

[About two-story and three-story tank container A]
If necessary, the full-tank container A1 is often installed in a two-story building at the same hydrogen station D location [approximate center views of FIGS. (A), (B)]. In order to make the two-story and three-story buildings safe and secure, the tank container A is provided with overlapping auxiliary pieces at the four corners of the container body 1 on the upper surface side of the tank container A, as shown in FIG. 16a is fixed by welding or the like.

As shown in FIG. 29, the stacking auxiliary piece 16a has a shape and configuration in which a plate piece is bent about 90 degrees in a plan view, and the container main body on the lower surface side of the tank container A on the second floor side. The four corners of 1 hold the stacking auxiliary pieces 16a at the four corners of the container body 1 on the top side of the tank container A on the first floor side, so that the tank container A on the second floor side is stacked without causing any deviation. can. An example of such a two-story building is shown in FIG. 1, 3, 24, and 25 are also disclosed when placed directly on the liquefied hydrogen transport system.

In the case of a three-story building, the four corners of the container body 1 on the bottom side of the tank container A, which is the third floor side, are on the upper side of the tank container A, which is the second floor side. The tank containers A on the third floor side can be stacked without any displacement by holding the stacking auxiliary pieces 16a at the four corners of the container body 1 on the upper surface side of the tank container A. A drawing of this three-story building is omitted. Also, the overlapping auxiliary piece 16a is described in the main drawings of the tank container A (FIGS. 4, 5, 14 to 20, 26 to 29, etc.). Further, as shown in FIG. 26(D), the upper side of the auxiliary stacking piece 16a is formed slightly open, and is often formed as an improved auxiliary stacking piece 16b so as to facilitate stacking on the second floor or the like.

In this way, a reach stacker or the like used at a wharf or the like is used for stacking and unloading of a two-story building, a three-story building, or more. Placing the full-tank container A1 directly at the hydrogen station D or the power plant E in this way also serves as an existing liquefied hydrogen storage tank. Furthermore, if a two-storied or three-storied building (including temporary installation) is made at the place where it is placed directly, it can be popularized in urban areas and the like. In this way, there is also the advantage of being able to provide equipment that can replace the expensive liquefied hydrogen storage tanks that exist in conventional or current hydrogen stations (current hydrogen stations).

[Other embodiments of tank container A]
As shown in FIG. 19, the rear side jack 3 that slides a little is basically the same as the front side jack, and the width of the jack 3 slides slightly (small widening). Specifically, a cylindrical fixing portion 33 is fixed to the rear member 13d at the rear end of the container body 1, and slide members 32, 32 are provided so that the cylindrical fixing portion 33 can slide outward on both sides. , hydraulic jacks 31, 31 are attached to the outer ends of the slide members 32, 32, respectively. The hydraulic jacks 31, 31 are composed of a cylinder portion 31a and a piston portion 31b that moves up and down. The widening of both front composite jacks 2, 2 in the width direction is hydraulically controlled, which has the advantage of being operable with a simple operation.

As described above, it is possible to avoid contact with the loading platform 6 by manually sliding it, although the width is about 10-odd centimeters to about 20 cm. Even in this case, the tank container A is safely loaded and separated from the loading platform 6 of the truck B by synchronizing the forward side composite jack 2 and the rear side jack 3 when they are raised and lowered by the driving force of the hydraulic pressure generator 7. Although the slide member 32 is a small slide, even if it is several tens of centimeters (approximately 30 to 40 cm), it may be included in the category of small width.

Specifically, in the hydraulic circuit having the hydraulic pressure generating device 7 shown in FIG. Width widening control of both slide members 32, 32 of No. 3 is performed (synchronized width widening). In addition, the second switching valve 73B is used to switch both the front composite jacks 2, 2 and the hydraulic jacks 21, 21 (both front composite jacks 2, 2) and 31, 31 (both rear jacks 3, 3). Each is constructed so that it can be raised and lowered at the same time (synchronized raising and lowering). Although the slide member 32 is a small slide, even if it is several tens of centimeters (approximately 30 to 40 cm), it may be included in the category of small width.

As shown in FIG. 20, the rear jack 3, which is reversible in a plan view, has an arm portion 35 provided in a bearing portion 34 so as to be reversible by approximately 180 degrees (small width expansion). Specifically, the U-shaped frame 34b of the bearing portion 34 with the vertical shaft 34a is fixed to the rear side members 13a and 13c at the rear end of the container body 1, respectively. The vertical shafts 34a, 34a of the respective bearings 34, 34 are reversible to the base-side cylindrical portion 35a at the base of one end of the trapezoidal arm portion 35, respectively. A distal cylindrical portion 35 b is fixed to the distal end of the arm portion 35 on the other end side (free end side).

Hydraulic jacks 31, 31 are attached to both the left and right tip cylindrical portions 35b, 35b. The hydraulic jack 31 is composed of a cylinder portion 31a and a piston portion 31b that moves up and down. When the arm portion 35 is closed [see FIG. 20(C)] or opened by inverting it [see FIGS. The description is omitted here. Further, the arm portion 35 has a trapezoidal shape as shown in FIG. 20, but it may be square, rectangular, or bar-shaped, and the shape is not limited.

With the configuration as described above, when the tank container A is loaded on the truck B, both the arm portions 35, 35 are closed and fixed as shown in FIG. 20(C). When the tank container A is separated from the truck B and placed directly on the site, the arms 35, 35 are spread out and operated. Even in this case, although it is a small width of about 20 cm to about 30 cm, by manually reversing it, contact with the loading platform 6 can be avoided, safe driving of the truck B can be ensured, and the front side composite jack 2 can be used. , and the rear jack 3 are synchronously lifted by the driving force of the hydraulic pressure generating device 7 to safely load and separate the tank container A on the loading platform 6 of the truck B.

[Regarding small and large expansion]
19(C) attached to the rear side of the tank container A, the cylindrical fixing portion 33 of both the rear jacks 3 shown in FIG. is the "small expansion", and the width expansion structure by opening and closing the arm portions 35, 35 shown in FIGS. On the other hand, as shown in FIGS. 4 and 5, slide members 22 are provided so as to slide outward on both sides of the cylindrical fixing portion 23 of both the front composite jacks 2 attached to the front side of the tank container A. , 22 is the "large expansion". For example, "large expansion" refers to a width expansion of at least 4.50 cm or more and about 1 m, and "small expansion" refers to a width expansion of about 2.30 cm or less.

In the present invention, the front end of the tank container A may be provided with a front composite jack 2 that can be widened as a "large expansion" and a rear jack 3 that is fixed or "small expansion" (small expansion length). The basic reason for these is that when the tank container A is loaded on the loading platform 6 of the truck B, the degree of non-contact with the piston portions 21b, 21b of the front side composite jack 2 is increased to improve the maneuverability of the truck B. This is to ensure greater safety. On the other hand, the rear side jack 3 is simply to ensure non-contact with the rear portion of the loading platform 6, and can be sufficiently handled by fixing or widening the width.

[Regarding another embodiment of tank container A: intermediate reinforcement]
An intermediate position jack 8 for reinforcing the tank container A is provided as needed at a substantially central position in the longitudinal direction (X-axis direction) of the tank container A (large type) shown in FIG. 22(A). . Specifically, the intermediate position jacks 8, 8 are provided at approximately the longitudinal center positions of the laterally elongated members 11a, 11c of the container body 1 so as to be slightly slidable (slightly widened) outward. The intermediate position jack 8 is composed of a slide member 82, a cylindrical fixing portion 83, a hydraulic jack 81, a cylinder portion 81a, and a piston portion 81b.

The cylindrical fixing portion 83 of the intermediate position jack 8 is fixed to the reinforcing member 16 of the container body 1, and the sliding member 82 is configured to be slidable on the cylindrical fixing portion 83, A hydraulic jack 81 is fixed to the tip of the slide member 82 . The hydraulic jack 81 is fixed. The hydraulic jack 81 is composed of a cylinder portion 81a and a piston portion 81b.

In the container body 1 of the tank container A configured as described above, the intermediate position jacks 8, 8 on both sides in the state where the slide is closed are at least equal to the width position of the truck B or protrude from the width position. [see dotted line in FIG. 22(C)]. Furthermore, as shown in FIG. 23, for reinforcing the tank container A, the horizontal members 11a and 11d of the container body 1 may be formed to have a considerably large section modulus to serve as reinforcing members.

The tank container A shown in FIG. 18 is a modified example of the container body 1 and is of a type that does not form a rectangular parallelepiped shape. Specifically, the frame-like portion composed of the upper horizontal members 11b and 11c, the front side member 12b, and the rear side member 13b is removed. Even with such a structure, by increasing the number of reinforcing diagonal members 14 on both sides, it is possible to compete in terms of strength. The tank container A of this type has an advantage that the hydrogen tank 4 can be easily taken out from the container body 1 and installed.
