Hydrogen tank support device for vehicles and drones {DEVICE FOR VEHICLES AND DRONE HYDROEN TANK SUPPORT}

The present invention relates to a hydrogen tank support device for vehicles and drones, and more specifically, to store hydrogen and to be mounted on a loading box provided in transport equipment such as vehicles or drones to quickly supply hydrogen to objects requiring hydrogen. A vehicle that protects the inner tank from radiant heat, minimizes heat conductivity, maintains the gap between the outer tank and the inner tank, and maintains its shape stably by suppressing vertical and horizontal movement of the inner tank. The purpose is to provide a hydrogen tank support device for drones.

Recently, the demand for energy has been continuously increasing due to the rapid development of industrialization and increase in population. Accordingly, there is an urgent need for alternative energy supply due to the depletion of fossil fuels. In particular, in the case of Korea, energy consumption is ranked among the top 10 in the world. Although we are consuming such a large amount of energy, we are dependent on foreign imports for more than 90% of the energy we use, so measures to secure energy are urgently needed.

Accordingly, hydrogen fuel is being considered as an alternative energy that is attracting attention to solve the complex energy problems facing the world.

This hydrogen fuel is not only the most abundant element on Earth after carbon and nitrogen, but is also a clean energy source that generates only a very small amount of nitrogen oxides during combustion and does not emit any other pollutants, and is a source of abundant energy that exists on Earth. It can be made using water as a raw material, and since it is recycled back to water after use, it can be said to be an optimal alternative energy source with no fear of depletion.

The most important challenge in using this hydrogen fuel is how to store hydrogen. Methods for storing hydrogen include compressing and storing hydrogen gas, storing it by liquefying it, or using a hydrogen storage alloy. However, the technology currently in use uses a method of compressing and storing hydrogen gas. there is. However, vaporized hydrogen has a small storage capacity and poor storage efficiency, so liquefied hydrogen is attracting attention as a form of storage and transportation in the future liquefied hydrogen energy society.

Here, liquid hydrogen refers to hydrogen gas that has been 'liquefied' like water. The liquid hydrogen storage method is to cool and store hydrogen at a cryogenic temperature (-253 degrees Celsius), producing about 240 times more hydrogen than gaseous hydrogen based on atmospheric pressure. You can save it. In addition, it has the highest energy storage density per unit volume and unit weight, and has the advantage of being able to be utilized immediately through simple vaporization without the need for other processes.

In addition, as the hydrogen market grows in the future, large-scale transportation of hydrogen by ship may occur, and among the above methods, the method of liquefying and storing hydrogen is recognized as a technology suitable for large-scale storage and long-distance transportation of hydrogen.

Currently, most technologies for liquefied hydrogen (LH2) storage tanks that store liquefied hydrogen are for small tanks for land use.

The structure of the existing liquefied natural gas (LNG) storage tank allows storage at a low pressure at a temperature of -162 degrees Celsius or lower, but liquefied hydrogen requires pressurization at a lower temperature than liquefied natural gas, so the previously known liquefied hydrogen is used. A more stringent solution than natural gas storage technology is needed.

로 극저온의 액화천연가스(-162

보다 더 낮은 액화 온도를 가지는 저비점 특성을 가지므로 액화천연가스보다 기화가 더 쉽게 촉진되며, 체적당 증발률(BOR: Boil-Off Rate)은 액화천연가스의 10배에 달한다.Liquid hydrogen has a liquefaction temperature of -253

Cryogenic liquefied natural gas (-162

Because it has a low boiling point characteristic with a lower liquefaction temperature, evaporation is promoted more easily than liquefied natural gas, and the evaporation rate per volume (BOR: Boil-Off Rate) is 10 times that of liquefied natural gas.

At this time, the device for storing liquefied hydrogen is largely accommodated inside a spherical external tank and the external tank, and may include a support for supporting the spherical internal tank and external tank for storing liquefied hydrogen.

However, the conventional liquefied hydrogen storage device had a minimal function of suppressing the flow such as vertical movement, horizontal movement, and rotation of the internal tank when the liquid hydrogen was vaporized and the pressure of the liquid hydrogen was generated or an earthquake occurred. There is a problem in that structural stability is not secured, such as not having a function to return to the original position if it floats.

Therefore, there is an urgent need to develop a device that can return the inner tank to its original position when it flows while minimizing the flow of the inner tank due to evaporation of liquefied hydrogen or an earthquake.

The hydrogen tank support device for vehicles and drones according to an embodiment of the present invention stores hydrogen and is mounted on a loading box provided in transport equipment (1) such as a vehicle or drone, to quickly deliver hydrogen to objects that need hydrogen. It can be supplied easily, and the inner tank (20) can be protected from radiant heat to minimize thermal conductivity and at the same time maintain the gap between the outer tank (10) and the inner tank (20), and the vertical and horizontal movement of the inner tank (20) can be maintained. It is a product that can maintain its shape stably, suppressing

The hydrogen tank support device for vehicles and drones according to an embodiment of the present invention is accommodated in an external tank 10 mounted on transport equipment 1 such as a vehicle or drone, and an internal space of the external tank 10, In order to support a hydrogen tank including an inner tank 20, the outer surface of which is spaced apart from the inner surface of the outer tank and a storage space for storing hydrogen formed therein, an outer tank 10 and an inner tank ( 20), and may include at least one of the first insulating part 30, the second insulating part 40, and the elastic support part 50.

The external tank 10 is exposed to the outside and is affected by the atmosphere, and in order to insulate the internal tank 20, the internal tank 20 is prevented from being exposed to the outside.

The external tank 10 functions to evenly support the internal pressure of the internal tank 20 by sharing the internal pressure applied to the internal tank 20.

The external tank 10 may be made of steel material to withstand stress, load, etc. transmitted from the internal tank 20.

That is, the external tank 10 may be made of a steel material, unlike the internal tank 20, which directly stores liquefied hydrogen.

This is because the influence of the cryogenic temperature of liquefied hydrogen is insignificant compared to the first insulating part 30, the second insulating part 40, and the elastic support part 50, which will be described later.

This external tank 10 is supported by a support 100 at a certain distance from the bottom of the loading box.

The supports 100 are applied in plural pieces and support the external tank 10 while being spaced apart from each other.

The upper portion of the support 100 that is in contact with the outer surface of the external tank 10 may be formed in a curved shape so as to be in close contact with the outer surface of the external tank 10.

The number of supports 100 applied varies depending on the size of the external tank 10.

The inner tank 20 is accommodated in the inner space of the outer tank 10, and its outer surface is spaced apart from the inner surface of the outer tank 10.

In addition, the internal tank 20 can store liquefied hydrogen by forming a storage space therein.

The inner tank 20 is in direct contact with liquefied hydrogen and is made of a material with excellent low-temperature characteristics that can withstand the extremely low temperature of liquefied hydrogen.

For example, the inner tank 20 may be made of aluminum or aluminum alloy material.

Due to the dual structure of the external tank 10 and the internal tank 20, the liquefied hydrogen stored inside the internal tank 20 can be maintained in a cryogenic state.

The outer tank 10 and the inner tank 20 described above may be formed in an oval or spherical shape so that the internal pressure of the liquefied hydrogen can be evenly distributed, and an example in which they are formed in an oval shape is shown in the drawing.

Additionally, a first pocket portion 60 accommodating a first insulating portion 30, which will be described later, is fixed to the inner surface of the external tank 10.

In addition, a second pocket portion 70 accommodating a second insulation portion 40, which will be described later, is fixed to the outer surface of the inner tank 20.

The first pocket portion 60 and the second pocket portion 70 may be formed of metal or synthetic resin.

And, the first pocket portion 60 and the second pocket portion 70 are installed to face each other.

Furthermore, the first pocket portion 60 and the second pocket portion 70 can apply a plurality of first insulation portions 30 and second insulation portions 40 to the outer tank 10 and the inner tank 20. It is applied in multiple pieces and placed at a certain distance from each other.

The first insulation unit 30 and the second insulation unit 40 perform the function of blocking heat transfer.

The first insulating part 30 is fixed to the inner surface of the external tank 10, and the second insulating part 40 is fixed to the outer surface of the internal tank 20 so as to face the first insulating part 30 and are spaced apart from each other. It is arranged properly.

The first insulation unit 30 and the second insulation unit 40 are applied in plural numbers to increase heat transfer blocking efficiency, and can be installed at regular intervals in the external tank 10 and the internal tank 20, respectively. .

The first insulation portion 30 and the second insulation portion 40 may be formed of hard wood for thermal insulation to block heat conduction.

Since hardwood has excellent temperature shielding properties, it can prevent the temperature of liquefied hydrogen from increasing by protecting the internal tank 20 from radiant heat and minimizing thermal conductivity.

In addition, the first insulation unit 30 and the second insulation unit 40 can prevent cold air from the internal tank 20 from being conducted to the external tank 10.

Additionally, the hardwood is made of a hard material and serves as a foundation to support the external tank 10. This will be explained in detail later.

Additionally, fixing grooves 30a and 40a are formed in approximately the central portion of the first insulating part 30 and the second insulating part 40, respectively, and the fixing grooves 30a of the first insulating part 30 and Elastic support parts 50 are inserted and fixed into the fixing grooves 40a of the second insulating part 40, respectively.

Meanwhile, the elastic support portion 50 is configured to elastically support the internal tank 20.

The elastic support portion 50 may be formed of a coil spring or a leaf spring to generate an elastic support force for the internal tank, and an example formed of a coil spring is shown in the drawing.

One side of the elastic support part 50 is inserted into and fixed to the fixing groove 30a of the first insulating part 30, and the other side is inserted into and fixed to the fixing groove 40a of the second insulating part 40.

These elastic supports 50 are disposed at least one on the upper, lower, left, right, front, and rear sides of the inner tank 20, and form the first and second insulation portions 30 and 20 respectively. Connect (40) respectively.

The elastic support portion 50 is formed of a coil spring or a leaf spring and is compressed to a certain level when an external force is applied, and when the external force is released, it is expanded by its own elastic force and restored to its original form.

Therefore, the elastic support portion 50 located on the upper side of the inner tank 20 elastically supports the upper surface of the inner tank 20 through the second insulation portion, thereby preventing the inner tank 20 from being exposed to internal pressure or various other factors. When an upward force is applied, the inner tank 20 is compressed to a certain level by pressure and then expands, lowering the inner tank 20 and returning it to its original position. That is, when a force acts to raise the inner tank, the elastic support portion 50 absorbs the force and suppresses the vertical rise of the inner tank 20.

In addition, the elastic support portion 50 located on the lower side of the inner tank 20 elastically supports the bottom of the inner tank 20 through the second insulation portion, thereby preventing the inner tank 20 from being exposed to internal pressure or various other factors. When a downward force is applied, the inner tank 20 is compressed to a certain level by pressure and then expands, thereby raising the inner tank 20 and returning it to its original position.

Of course, the elastic support part 50 located on the left or right side of the inner tank 20 also elastically supports the left or right side of the inner tank 20 via the second insulation part, so that the inner tank 20 is horizontal. Prevents being pushed in any direction (forward, backward, left, right).

In addition, the elastic support part 50 can absorb the rotational force of the internal tank 20 and return it to its original position.

Meanwhile, the liquefied hydrogen tank support device according to an embodiment of the present invention may further include at least one of an insulating material 80 for thermal insulation and a thermal insulation unit 90 for thermal insulation.

Although the drawing shows an example in which the insulation material 80 and the warming unit 90 are applied simultaneously, only the insulation material 80 or only the insulation unit 90 may be applied.

The insulation material 80 may be installed in an uninstalled section on the outer surface of the inner tank 20 where the second insulation part is not installed.

The insulation material 80 may be formed of a sheet of urethane material or glass wool material.

의 온도를 유지할 수 있도록 한다.The insulation material 80 prevents the inner tank 20 from leaking out and prevents solar heat and radiant heat acting on the outer tank 10 from being conducted to the inner tank 20. As a result, liquefied hydrogen is -253

to maintain the temperature.

At this time, if the insulation material 80 is thin, it can be applied in a form of stacking at least two or more layers.

The thermal insulation unit 90 may be formed of perlite in powder form and filled in the space between the external tank 10 and the insulation material 80.

At this time, the thermal insulation unit 90 can be filled while creating a vacuum in the space between the external tank 10 and the insulation material 80.

For this purpose, an intake port and a filling port are formed in the external tank 10, respectively, and a known air suction device capable of sucking air is connected to the intake port to remove air present in the space between the external tank 10 and the insulation material 80. By sucking in air and at the same time filling the filling port with perlite in powder form through a known air supply device that generates compressed air, such as an air compressor, the space between the external tank 10 and the insulation material 80 is vacuum-insulated. can do.

At this time, the intake port and filling port may be closed with a stopper (not shown) when the vacuum and pearlite filling operations are completed.

By creating a vacuum in the space between the external tank 10 and the insulation material 80, convection can be prevented from occurring, thereby preventing the temperature of the internal tank 20 and the liquefied hydrogen from increasing.

Furthermore, the thermal insulation unit 90 protects the internal tank 20 from radiant heat by insulating the space between the external tank 10 and the insulation material 80 and minimizes thermal conductivity, thereby preventing the temperature of the internal tank 20 from increasing. This can prevent liquefied hydrogen from vaporizing.

Additionally, when the elastic support part 50 is filled with the thermal insulation part 90 through the space between the first insulation part 30 and the second insulation part 40, the elastic support part 50 can have a cushioning effect. There will be no more.

Accordingly, the elastic support portion 50 may be entirely surrounded by the curtain 130 made of non-woven or cloth material.

The upper and lower sides of the curtain 130 are fixed to the outer periphery of the first pocket portion 60 and the second pocket portion 70 through a fixing device such as a bolt or piece, and the first insulating portion 30 and the second pocket portion 70 are fixed to the outer periphery of the curtain 130. 2 The insulating part 40, the elastic support part 50, and the first pocket part 60 and the second pocket part 70 can be wrapped at the same time.

This curtain 130 can prevent the thermal insulation unit 90 from filling the space between the first and second insulation units 30 and 40 and the space formed in the elastic support unit 50 itself.

Next, with reference to FIGS. 4 and 5, the reinforcement portion 110 applied to the hydrogen tank support device for vehicles and drones according to an embodiment of the present invention will be described.

Figure 4 is a front view showing the reinforcement applied to the hydrogen tank support device for vehicles and drones according to an embodiment of the present invention, and Figure 5 is a reinforcement applied to the hydrogen tank support device for vehicles and drones according to an embodiment of the present invention. This is a floor plan showing wealth.

The load of the external tank 10 and the internal tank 20 is transmitted to the lower part of the support 100.

Therefore, in order to ensure the structural stability of the support 100, the external tank 10, and the internal tank 20, the support 100 must be reinforced.

The reinforcement part 110 includes a receiving box 111, a corrugated support part 112, a first wrapping part 113, a second wrapping part 114, and a flow suppression part ( 115), a metal weight part 116, a measuring part 117, a support plate 118, a tube 119, a housing 120, and a pump 121. .

The receiving box 111 may be fixed to the bottom of the loading box through bolts.

The receiving box 111 is formed in the shape of a rectangular box with an open upper surface and a receiving space formed inside, so that the lower side of the support 100 can be accommodated in the receiving space.

The waveform supports 112 are each accommodated in the receiving space of the receiving box 111, and are located on the front, rear, left, and right sides of the support 100 to prevent the support 100 from shaking in the front, rear, left, and right directions. As each is arranged, the upper and lower sides are coupled to the support 100 and the receiving box 111 in an inclined structure, respectively.

The waveform support portion 112 is formed in a waveform shape to cushion and support the support 100, and may be made of a metal material.

These waveform supports 112 elastically support the front, rear, left, and right sides of the support 100, respectively, so that the support 100 can withstand the load of the external tank 10 and the internal tank 20, earthquakes, and various other Prevents bending due to external force.

The first wrapping portion 113 is in contact with the left side of the support 100, and is bent in a right angle direction at both ends of the first member 1131 and the first member 1131 on which the first fastening hole 1131a is formed. It may include a second member 1132 that is in contact with 1/2 areas of the front and rear surfaces of the support 100 and has a second fastening hole 1132a formed thereon.

The second wrapping portion 114 is in contact with the right side of the support 100, and is bent in a right angle direction at both ends of the third member 1141 and the third member 1141 on which the third fastening hole 1141a is formed, respectively, to provide support. It may include a fourth member 1142 that is in contact with the remaining 1/2 area of the front and rear surfaces of 100 and has a fourth fastening hole 1142a formed thereon.

The flow suppression unit 115 penetrates from the outside of the box in the direction of the receiving space and includes the first fastening hole 1131a, the second fastening hole 1132a, the third fastening hole 1141a, and the fourth fastening hole 1142a. ) are each fastened to each other, and the ends pressurize and secure the support 100, thereby suppressing the flow of the support 100 and ensuring the structural stability of the external tank 10, the internal tank 20, and the support 100. .

In this way, after fixing the support 100 with the flow restraining part 115, the receiving box 111 is accommodated in the inner space of the metal weight part 116.

The metal weight portion 116 may be formed in the shape of a rectangular box with an open upper surface and a receiving space formed inside.

The receiving box 111 is accommodated in the receiving space of the metal weight portion 116.

The metal weight portion 116 may be made of a metal material to prevent the support 100 from flowing on its own when trying to move in the horizontal direction, and may have a weight of approximately 50 kg to 200 kg.

Since the metal weight portion 116 does not flow on its own, it can also suppress the flow of the support 100.

The measuring unit 117 is arranged to face the front, rear, left, and right sides of the support 100, respectively, and measures the distance to the support 100.

The measuring unit 117 may be applied as a distance measuring device using a laser or any of various measuring devices that measure the distance to an object encountered.

The support plate 118 is arranged to face the front, rear, left, and right sides of the support 100, respectively.

The tube 119 is disposed on the front, rear, left, and right sides of the support 100, and a support plate 118 is coupled to one side.

The inner space of the tube 119 is filled with approximately 80% to 90% of water.

The tube 119 may gradually expand as it is filled with water.

This tube 119 may be formed into a substantially circular, oval, or polygonal shape.

Tubes 119 are each accommodated inside the housing 120.

The housing 120 is fixed to the upper surface of the metal weight portion 116 to prevent the tube 119 from flowing.

The pump 121 is connected to a separate water storage tank (not shown) and can supply water to the inside of the tube 119.

The measuring unit 117 measures the distance to the support 100 in real time, and when the measured distance to the support 100 becomes shorter than the preset distance, the measurement unit 117 transmits the data to an electrically connected control unit (not shown).

When a signal is transmitted from the measuring unit 117, the control unit operates the pump 121 to supply about 20% to 10% of water to the inside of the tube 119, thereby expanding the tube 119.

At this time, when the control unit receives a signal from the measurement unit 117, it can be programmed to transmit the abnormality of the support 100 to the manager's portable terminal and the manager PC.

When the tube 119 is expanded, the support plate 118 comes into close contact with the support 100 to support it.

The support plate 118 supports the support 100, and the tube 119 supports the support plate 118 at a constant weight, so even if a shock or earthquake is applied to the support 100, the support 100 can prevent it from flowing.

The amount of water filled in the tube 119 may vary depending on the size or weight of the external tank 10, internal tank 20, and support 100.

Meanwhile, although not shown in the drawing, a warming unit (not shown) formed of a heating line or heating coil that operates by receiving power may be installed inside the housing 120.

In addition, a temperature measuring device (not shown) to measure temperature may be installed on the outer or inner surface of the housing 120.

The temperature measuring device is a known product capable of measuring temperature and is configured to prevent the water filled inside the tube 119 from freezing when the temperature is low, such as in winter.

For this purpose, the temperature measuring device is electrically connected to the control unit described above.

The temperature measuring device measures the temperature in real time and transmits it to the control unit.

The control unit receives the temperature in real time from the temperature measuring device, and if the temperature transmitted from the temperature measuring device is a preset temperature, for example, 0°C, which is the freezing temperature of ice, it applies power to the warming unit to control the temperature of the tube 119. It is programmed to prevent the water filled inside from freezing.

Additionally, the control unit can be programmed to cut off the power applied to the warming unit when the temperature transmitted from the temperature measuring device is 1°C or higher.

A person skilled in the art to which the present invention pertains will understand that the present invention can be implemented in other specific forms without changing its technical idea or essential features. Therefore, the embodiments described above should be understood in all respects as illustrative and not restrictive.
