Abstract

A combustible gas supply unit is for supplying compressed combustible gas to a dispenser. The combustible gas supply unit includes a high pressure gas facility for handling compressed combustible gas, a base plate having the high pressure gas facility installed thereon and a barrier supported by the base plate to surround at least a part of an outer periphery of the high pressure gas facility. A barrier is shaped to surround at least a part of an outer periphery of the high pressure gas facility and includes a part to be supported by a base plate having the high pressure gas facility installed thereon.

First claim

The invention claimed is:

1. A combustible gas supply unit for supplying compressed combustible gas to a dispenser, comprising:
a high pressure gas facility for handling compressed combustible gas;
a base plate having the high pressure gas facility installed thereon; and
a barrier that is directly or indirectly supported by the base plate to surround at least a part of an outer periphery of the high pressure gas facility; wherein
the high pressure gas facility is housed in a unit body of a housing structure,
the barrier includes a part extending further upward than an upper surface of the unit body or further laterally than a side surface of the unit body,
the barrier is constituted by a plate structured to withstand an impact caused by an explosion of the compressed combustible gas, and
the barrier is formed of a steel plate.

2. A combustible gas supply unit according to claim 1 , wherein the high pressure gas facility handles hydrogen gas.

3. A combustible gas supply unit according to claim 1 , wherein
the base plate is fixed to a ground surface and
the barrier is fixed to the base plate.

4. A combustible gas supply unit according to claim 2 , wherein
the base plate is fixed to a ground surface and
the barrier is fixed to the base plate.

5. A combustible gas supply unit for supplying compressed combustible gas to a dispenser, comprising:
a high pressure gas facility for handling compressed combustible gas;
a base plate having the high pressure gas facility installed thereon; and
a barrier that is directly or indirectly supported by the base plate to surround at least a part of an outer periphery of the high pressure gas facility; wherein
the high pressure gas facility is housed in a unit body of a housing structure,
the barrier includes a part extending further upward than an upper surface of the unit body or further laterally than a side surface of the unit body,
the barrier is constituted by a plate structured to withstand an impact caused by an explosion of the compressed combustible gas,
the base plate is fixed to a ground surface,
the barrier is fixed to the base plate,
the combustible gas supply unit further comprising a pillar provided upright on the base plate,
the barrier is fixed to the pillar.

6. A combustible gas supply unit according to claim 4 , further comprising a pillar provided upright on the base plate, wherein
the barrier is fixed to the pillar.

7. A combustible gas supply unit according to claim 5 , wherein
a plurality of the pillars are provided while being spaced from each other,
the combustible gas supply unit further comprises a beam stretched between the plurality of pillars and
the barrier is fixed to the beam.

8. A combustible gas supply unit according to claim 7 , wherein
the base plate, the pillars and the beam constitute the unit body of the housing structure.

9. A barrier constituting a part of a combustible gas supply unit with a high pressure gas facility for handling compressed combustible gas, wherein
the barrier is shaped to surround at least a part of an outer periphery of the high pressure gas facility and includes a part to be directly or indirectly supported by a base plate having the high pressure gas facility installed thereon,
the barrier includes a part that is shaped to extend further upward than an upper surface of a unit body that houses the high pressure gas facility or further laterally than a side surface of the unit body, and
the barrier is constituted by a steel plate structured to withstand an impact caused by an explosion of the compressed combustible gas.
