上記先行技術に係る燃料水素供給基地は、車載充填水素タンクの仕様に合わせて安定して燃料水素を供給するために、燃料水素供給ラインにレギュレータを配置し、燃料水素の供給状態を監視し、この監視データを制御装置に取り込んで安定的に燃料水素を車載タンクに供給するようにしたものである。   In order to supply fuel hydrogen stably in accordance with the specifications of the on-vehicle filling hydrogen tank, the fuel hydrogen supply base according to the above prior art arranges a regulator in the fuel hydrogen supply line, monitors the supply state of fuel hydrogen, This monitoring data is taken into the control device, and fuel hydrogen is stably supplied to the vehicle-mounted tank.

上記先行技術では、一般的な車両への燃料水素の供給を主とするものであるから燃料水素の供給基地へ向かうのは容易であるが、電動車椅子のように、燃料の充填が小規模で、燃料水素基地に向かうことが困難な用途に対する考慮は払われていない問題がある。   In the above prior art, since fuel hydrogen is mainly supplied to a general vehicle, it is easy to go to the fuel hydrogen supply base. However, like an electric wheelchair, the fuel filling is small. However, there is a problem that consideration is not given to applications that are difficult to go to the fuel hydrogen base.

上記の問題に鑑みこの発明は、電動車椅子のように燃料水素の供給規模(充填規模）が小さく、遠くの燃料水素基地に向かうことが困難な場合のために簡単で安全に多数の燃料水素基地を設置できる技術を提供することを課題とする。   In view of the above problems, the present invention is simple and safe for a large number of fuel hydrogen bases in the case where the supply scale (filling scale) of fuel hydrogen is small and it is difficult to go to a distant fuel hydrogen base like an electric wheelchair. It is an issue to provide a technology that can install the system.

上記課題を解決するためにこの発明は、燃料電池の燃料である水素の供給圧力を所定圧力に調整する圧力調整器１９を備えた水素供給源と、上記水素供給源に複数の水素吸蔵合金ボンベ１３を一括して繋ぐことができる接続部とからなり、上記水素供給源と上記水素吸蔵合金ボンベ１３との接続をクイック接続機構としたものであり、上記クイック接続機構は、水素吸蔵合金ボンベ１３側に設けた水素受・給プラグ３０と、水素供給源側に設けたソケット２９とからなり、上記水素受・給プラグ３０は上記ソケット２９内に嵌り合いソケット２９の内周またはプラグの外周に嵌められたシールリング３３に接して気密に接続され、ソケット２９と水素受・給プラグ３０との間に両者の着脱機構を設けてなる。
上記燃料水素供給装置１０の水素吸蔵合金ボンベ１３を収容する架台２７には、水素吸蔵合金ボンベ１３を斜め下向きに誘導する収容部が開口し、この開口から水素受・給プラグ３０部分を斜め下向きにして水素吸蔵合金ボンベ１３を落とし込むことによりをクイック接続するようにした。また、好ましくは、上記燃料水素供給マウント２５またはソケット２９に異物侵入防止シャッタ２５ｓ，２９ｓを設けてなる。 In order to solve the above-described problems, the present invention provides a hydrogen supply source including a pressure regulator 19 that adjusts a supply pressure of hydrogen as fuel for a fuel cell to a predetermined pressure, and a plurality of hydrogen storage alloy cylinders in the hydrogen supply source. 13 is connected to the hydrogen supply source and the hydrogen storage alloy cylinder 13 as a quick connection mechanism. The quick connection mechanism is a hydrogen storage alloy cylinder 13. A hydrogen receiving / supply plug 30 provided on the side and a socket 29 provided on the hydrogen supply source side. The hydrogen receiving / supply plug 30 fits into the socket 29 and is provided on the inner periphery of the socket 29 or the outer periphery of the plug. The seal ring 33 is fitted in an airtight manner, and an attachment / detachment mechanism is provided between the socket 29 and the hydrogen receiving / supplying plug 30.
The frame 27 for accommodating the hydrogen storage alloy cylinder 13 of the fuel hydrogen supply device 10 has an opening for guiding the hydrogen storage alloy cylinder 13 obliquely downward, through which the hydrogen receiving / supply plug 30 portion is inclined obliquely downward. The quick connection was made by dropping the hydrogen storage alloy cylinder 13. Preferably, the fuel hydrogen supply mount 25 or the socket 29 is provided with shutters 25s and 29s for preventing foreign matter from entering.

水素吸蔵合金ボンベ１３の表面温度を計測する温度センサＴｒと、外気温を計測する温度センサ１００と、上記ソケット２９の直前の供給水素圧力を計測する圧力センサ５２との出力を演算装置に入力し、この入力と予め演算装置に書き込んだデータとを比較して水素充填状態を判断し、水素供給を遮断および／または警報を発するようにし、上記水素充填状態の判断を、架台２７に収容した水素吸蔵合金ボンベ１３を一括して行うか、グループごとに行うか、一本宛個別に行うかのいずれかを採用してなる。   The outputs of the temperature sensor Tr for measuring the surface temperature of the hydrogen storage alloy cylinder 13, the temperature sensor 100 for measuring the outside air temperature, and the pressure sensor 52 for measuring the supply hydrogen pressure immediately before the socket 29 are input to the arithmetic unit. The hydrogen filling state is judged by comparing this input with the data previously written in the arithmetic unit, the hydrogen supply is shut off and / or an alarm is issued, and the determination of the hydrogen filling state is determined by the hydrogen stored in the gantry 27. Either the occlusion alloy cylinder 13 is performed in a lump, is performed for each group, or is individually performed for one.

上記の如く構成するこの発明によれば、燃料水素の供給圧力を周辺技術に相応して安全な圧力に調整することにより、燃料水素供給基地を随所に設置可能となる。また、基地と水素吸蔵合金ボンベとの接続がクイック接続できるようになり、さらに、複数本の水素吸蔵合金ボンベに供給できるので利用者に掛ける負担を大幅に軽減し、異物侵入防止シャッタを付設することにより暴発の防止効果が得られる。また、水素吸蔵合金ボンベへの水素の充填を効率よく行うことができる。   According to the present invention configured as described above, the fuel hydrogen supply base can be installed everywhere by adjusting the fuel hydrogen supply pressure to a safe pressure corresponding to the surrounding technology. In addition, the connection between the base and the hydrogen storage alloy cylinder can be made quick, and furthermore, since it can be supplied to a plurality of hydrogen storage alloy cylinders, the burden placed on the user is greatly reduced, and a foreign substance intrusion prevention shutter is attached. As a result, an explosion prevention effect can be obtained. Further, hydrogen can be efficiently filled into the hydrogen storage alloy cylinder.

次にこの発明の実施の形態を、図面を参照しながら説明する。図１は本発明に係る燃料水素供給装置１０のキャビネット１１の背面を一部剥いで水素ボンベ１２と、水素ボンベ１２から供給される源圧（一次圧）を所定の供給圧に圧力調整する配管系を示す。図２は同キャビネット１１の側面の一部を剥ぎ、供給圧に調整した燃料水素を水素吸蔵合金ボンベ１３に供給している状態を示す図、図３は図２における燃料水素供給マウント２５に付設された異物侵入防止シャッタ２５ｓ部分の拡大図、図４は同じく水素吸蔵合金ボンベ１３に燃料水素を供給している状態の正面図、図５は同キャビネット１１の背面図である。   Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a hydrogen cylinder 12 by partially peeling the back surface of a cabinet 11 of a fuel hydrogen supply apparatus 10 according to the present invention, and piping for adjusting the source pressure (primary pressure) supplied from the hydrogen cylinder 12 to a predetermined supply pressure. Indicates the system. FIG. 2 is a view showing a state in which a part of the side surface of the cabinet 11 is peeled off and fuel hydrogen adjusted to the supply pressure is supplied to the hydrogen storage alloy cylinder 13, and FIG. 3 is attached to the fuel hydrogen supply mount 25 in FIG. 4 is an enlarged view of the foreign matter intrusion prevention shutter 25s portion, FIG. 4 is a front view of the hydrogen storage alloy cylinder 13 supplied with fuel hydrogen, and FIG.

図１に示すようにこの実施例では、キャビネット１１の背面に観音開きの扉１４が設けられてあり、この扉１４を開いて二本の水素ボンベ１２を収容できるようになっており、各ボンベ１２から管路１５が延び、それぞれ水素ガスの管路１５を開閉するバルブ１６が設けられ、その下流で合流し一次圧を示す圧力計１７を設けている。   As shown in FIG. 1, in this embodiment, a double door 14 is provided on the rear surface of the cabinet 11 so that the two hydrogen cylinders 12 can be accommodated by opening the door 14. A pipe 15 extends from each of the pipes, and a valve 16 is provided for opening and closing the pipe 15 for hydrogen gas. A pressure gauge 17 is provided downstream of the pipe 15 to indicate the primary pressure.

合流した管路１８の途中で二次側圧力が、例えば１３ＭＰａになるように設定したレギュレータ１９が取付けられ、このレギュレータ１９には一次・二次圧を示す圧力計２１，２２が付設され、二次圧側の管路２３はバルブ２４を介して燃料水素供給マウント２５（図２参照）に繋がっている。なお、キャビネット１１の正面には一次管路１５と二次管路２３から導出管が延びて一次圧力と二次圧力を示す圧力計１７，２６が設けられている。   A regulator 19 is set in the middle of the joined pipe 18 so that the secondary pressure becomes, for example, 13 MPa. The regulator 19 is provided with pressure gauges 21 and 22 indicating primary and secondary pressures. The secondary pressure side pipe line 23 is connected to a fuel hydrogen supply mount 25 (see FIG. 2) via a valve 24. In addition, pressure gauges 17 and 26 indicating the primary pressure and the secondary pressure are provided on the front face of the cabinet 11 by extending the outlet pipe from the primary pipe 15 and the secondary pipe 23.

図２，図３，図４に示すようにキャビネット１１の正面下部には水素吸蔵合金ボンベ１３の架台２７（４列×３段＝１２個）が設けられ、架台２７の下部に燃料水素供給マウント２５がそれぞれ配置されている。   2, 3, and 4, a frame 27 (4 rows × 3 levels = 12) of hydrogen storage alloy cylinders 13 is provided in the lower front portion of the cabinet 11, and a fuel hydrogen supply mount is mounted below the frame 27. 25 are arranged.

図３は燃料水素供給マウント２５に塵埃あるいは油分などが侵入しないように異物侵入防止シャッタが付設されている。ヒンジによって支持されたシャッタ２５ｓは、水素吸蔵合金ボンベ１３の水素受・給プラグ３０をトーションスプリングＳの付勢に抗して差し込むと開き、抜き取ると閉じる。この図でシャッタ２５ｓは片開きになっているが観音開きとすることもできる。   In FIG. 3, a foreign matter intrusion prevention shutter is attached so that dust or oil does not enter the fuel hydrogen supply mount 25. The shutter 25s supported by the hinge opens when the hydrogen receiving / supply plug 30 of the hydrogen storage alloy cylinder 13 is inserted against the urging force of the torsion spring S, and closes when the hydrogen receiving alloy plug 30 is removed. In this figure, the shutter 25s is a single opening, but it can also be a double door opening.

上記架台２７は、燃料水素を吸蔵した吸蔵合金が、水素吸蔵量−吸蔵圧力が大きくなるに従って温度上昇することを考慮して、パンチングネット２８などの素材を採用して放熱するようにしている。なお、図５はキャビネット１１の背面図である。   The gantry 27 uses a material such as a punching net 28 to dissipate heat in consideration of the fact that the temperature of the occlusion alloy that occludes fuel hydrogen rises as the hydrogen occlusion amount-occlusion pressure increases. FIG. 5 is a rear view of the cabinet 11.

図６（ａ）は、燃料水素供給マウント２５と水素吸蔵合金ボンベ１３と（図２参照）をクイック接続する一形態を示し、燃料水素供給マウント２５側にソケット２９が形成されており、このソケット内に水素吸蔵合金ボンベ側の水素受・給プラグ３０が嵌り合い、ソケット２９の底部内周に環状凹溝３１と凹球面３２が形成され、上記環状凹溝３１にシールリング３３が嵌められ、上方はテーパー段部３４になって内径が大きくなり、その上部に、雌形割りテーパー片３６が嵌る窪所３５が形成されている。なお、ソケット２９の底部内周に設けた環状凹溝とシールリングを無しにして、後述する水素受・給プラグの先端外周に環状凹溝を設け、これにシールリングを嵌めるようにしても良い。   FIG. 6A shows an embodiment in which the fuel hydrogen supply mount 25 and the hydrogen storage alloy cylinder 13 (see FIG. 2) are quickly connected, and a socket 29 is formed on the fuel hydrogen supply mount 25 side. A hydrogen receiving / supply plug 30 on the hydrogen storage alloy cylinder side is fitted inside, an annular groove 31 and a concave spherical surface 32 are formed on the inner periphery of the bottom of the socket 29, and a seal ring 33 is fitted in the annular groove 31; The upper part is a tapered step 34 and the inner diameter is increased, and a recess 35 into which the female split taper piece 36 fits is formed at the upper part. In addition, without the annular groove and the seal ring provided on the inner periphery of the bottom of the socket 29, an annular groove may be provided on the outer periphery of the tip of the hydrogen receiving / supplying plug, which will be described later, and the seal ring may be fitted thereto. .

上記窪所３５には下面がテーパーになった雌形割りテーパー片３６が嵌り、この雌形割りテーパー片３６には円孔３７が設けられ、この円孔３７には偏心カム３８が嵌り、この偏心カム３８の回転により雌形割りテーパー片３６が水素受・給プラグ３０に向かって進退する。   A female split taper piece 36 having a tapered lower surface is fitted into the recess 35, and a circular hole 37 is provided in the female split taper piece 36, and an eccentric cam 38 is fitted into the circular hole 37. The female split taper piece 36 advances and retracts toward the hydrogen receiving / supply plug 30 by the rotation of the eccentric cam 38.

一方、水素受・給プラグ３０の先端はソケット２９の底部（小径部）に嵌り、その先端で球面３９を形成し、大径部４０の肩部４１にはテーパーが形成され、このテーパーの上面に当接した雌形割りテーパー片３６の進退により水素受・給プラグ３０の先端がソケット２９側に押しつけられるようになっている。   On the other hand, the tip of the hydrogen receiving / supplying plug 30 is fitted into the bottom (small diameter portion) of the socket 29, and the tip of the socket forms a spherical surface 39. The shoulder 41 of the large diameter portion 40 is tapered, and the upper surface of this taper. The tip of the hydrogen receiving / supply plug 30 is pressed against the socket 29 side by the advancement and retraction of the female split taper piece 36 in contact with the socket 29.

図６（ｂ）は、上記ソケット２９の上面に異物侵入防止シャッタを設けた機構的説明図でソケット２９の上方に支点軸Ｐを設け、この支点軸Ｐから延びたアームの先端にローラーＲを設け、支点軸から斜め下に延びるアームの下端はシャッタ２９ｓのブラケットＢに接続（作用点Ｗ）される。なお、作用点Ｗのアームの孔はシャッタを水平に移動させるために長孔にしてある。   FIG. 6B is a mechanical explanatory view in which a foreign matter intrusion prevention shutter is provided on the upper surface of the socket 29. A fulcrum shaft P is provided above the socket 29, and a roller R is attached to the tip of an arm extending from the fulcrum shaft P. The lower end of the arm that is provided and extends obliquely downward from the fulcrum shaft is connected to the bracket B of the shutter 29s (operation point W). The hole of the arm at the point of action W is a long hole for moving the shutter horizontally.

このように構成するシャッタ２９ｓはプラグ３０が差し込まれるとローラーＲが押えられ支点軸を中心にアームが矢印の方向に回りシャッタが開き、プラグを抜き去ると自動的の閉じることとなる。ここで、支点軸Ｐにはトーションスプリングを設けてもよく、作用側のアームを絶えず振り上げ状態にして自動的に閉じるようにすることもできる。   When the plug 30 is inserted into the shutter 29s configured as described above, the roller R is pressed, the arm rotates around the fulcrum shaft in the direction of the arrow, and the shutter opens, and when the plug is removed, the shutter 29s is automatically closed. Here, the fulcrum shaft P may be provided with a torsion spring, and the working side arm can be constantly swung up to be automatically closed.

図７（ａ）は、別のソケット２９と水素受・給プラグ３０（図６（ａ）参照）とのクイック接続形態で、水素受・給プラグ３０の外周に環状凹溝４２ａを形成し、ソケット２９の内面にプランジャー４３が嵌まる複数個の穴４４を設け、この穴４４に押しバネ４５を介してボールプランジャー４６を装入したものである。   FIG. 7A is a quick connection configuration between another socket 29 and the hydrogen receiving / supplying plug 30 (see FIG. 6A), and an annular groove 42a is formed on the outer periphery of the hydrogen receiving / supplying plug 30; A plurality of holes 44 into which the plunger 43 is fitted are provided on the inner surface of the socket 29, and a ball plunger 46 is inserted into the hole 44 via a push spring 45.

また、図７（ｂ）は、さらに別のソケット２９と水素受・給プラグ３０（図６（ａ）参照）とのクイック接続形態で、水素受・給プラグ３０の外周に環状Ｖ形凹溝４２ｂを形成し、ソケット２９の内面にプランジャー４３が嵌まる複数個の穴４４を設け、この穴４４に押しバネ４５を介して屈折リンクプランジャー４７を装入したものである。   FIG. 7B shows a quick connection configuration of another socket 29 and a hydrogen receiving / supplying plug 30 (see FIG. 6A). An annular V-shaped groove is formed on the outer periphery of the hydrogen receiving / supplying plug 30. 42b is formed, and a plurality of holes 44 into which the plungers 43 are fitted are provided on the inner surface of the socket 29, and the refractive link plungers 47 are inserted into the holes 44 via the push springs 45.

上記二つの形態では、押しバネの付勢に抗して水素受・給プラグを押し込むと、環状半円凹溝にボールプランジャーが嵌まるか、環状Ｖ形凹溝に屈折リンクプランジャーが嵌って水素受・給プラグを押し込んだ状態が維持され、外すときは押しバネの付勢に抗して水素受・給プラグを引き抜くことができる。   In the above two forms, when the hydrogen receiving / supply plug is pushed in against the bias of the push spring, the ball plunger is fitted into the annular semicircular groove or the refractive link plunger is fitted into the annular V-shaped groove. Thus, the state in which the hydrogen receiving / feeding plug is pushed in is maintained, and when removing, the hydrogen receiving / feeding plug can be pulled out against the biasing force of the push spring.

また、別のクイック接続機構として水素受・給プラグとソケットとの間にバヨネットマウントを構成することもできる。   As another quick connection mechanism, a bayonet mount can be formed between the hydrogen receiving / supply plug and the socket.

図８は、燃料水素を充填した水素吸蔵合金ボンベ１３を電動車椅子５０の架台５１に装填している状態を示す。この場合においても、上記実施の形態のソケット２９と水素受・給プラグ３０とのクイック接続を適用することができる。   FIG. 8 shows a state in which the hydrogen storage alloy cylinder 13 filled with fuel hydrogen is loaded on the mount 51 of the electric wheelchair 50. Also in this case, the quick connection between the socket 29 and the hydrogen receiving / supplying plug 30 of the above embodiment can be applied.

図９は、水素吸蔵合金ボンベ１３への満充填制御あるいは、燃料水素充填時の水素吸蔵合金ボンベ１３の温度上昇抑制のための回路図を示し、架台２７には水素吸蔵合金ボンベ１３の表面温度を検出する温度センサＴｒが付設され、二次管路２３の各段の分岐部にはソレノイドバルブＳｖが付設され、各分岐管には圧力センサ５２が付設されている。   FIG. 9 is a circuit diagram for controlling the full filling of the hydrogen storage alloy cylinder 13 or suppressing the temperature rise of the hydrogen storage alloy cylinder 13 during fuel hydrogen filling. The surface 27 of the hydrogen storage alloy cylinder 13 is provided on the gantry 27. A temperature sensor Tr is attached to each branch, a solenoid valve Sv is attached to each branch of the secondary pipe 23, and a pressure sensor 52 is attached to each branch.

上記温度センサＴｒの出力と圧力センサ５２の出力は制御・演算装置に入力され、予め演算装置に書き込まれたデータと比較演算されて水素吸蔵合金ボンベ１３が満充填されたことを判断しソレノイドバルブＳｖを閉じるとともに、必要ならば警報器５３により満充填を報知するようにできる。また、燃料水素を充填するとき水素吸蔵合金ボンベ１３の温度が上昇すると充填効率が低下し、かつ安全性が阻害されるので設定された温度以上になると制御装置から指令が出されてファンモータが作動するようになっている。なお、上記制御・演算装置の電源は、商用電源、太陽光発電・燃料電池など適宜採用することができる。   The output of the temperature sensor Tr and the output of the pressure sensor 52 are input to the control / arithmetic unit, and compared with data previously written in the arithmetic unit to determine that the hydrogen storage alloy cylinder 13 is fully filled, and the solenoid valve While closing Sv, if necessary, the alarm device 53 can notify full filling. Further, when the temperature of the hydrogen storage alloy cylinder 13 rises when filling the fuel hydrogen, the filling efficiency is lowered and the safety is hindered. When the temperature exceeds the set temperature, a command is issued from the control device and the fan motor is turned on. It comes to work. Note that the power source of the control / arithmetic apparatus may be a commercial power source, a solar power generation / fuel cell, or the like as appropriate.

また簡易で安価な満充填制御手段として、上記圧力センサ５２の代わりに外気温センサ１００を設置し（図９参照）、水素吸蔵合金ボンベ側の温度センサＴｒと外気温センサ１００の両出力とを制御・演算装置に入力し、両者の差がゼロになると満充填と判断し水素供給を停止するものを採用することができる。   Further, as a simple and inexpensive full filling control means, an outside air temperature sensor 100 is installed instead of the pressure sensor 52 (see FIG. 9), and both the temperature sensor Tr on the hydrogen storage alloy cylinder side and the outputs of the outside air temperature sensor 100 are used. When the difference between the two is input to the control / arithmetic unit and becomes zero, it is determined that the fuel is fully charged and the hydrogen supply is stopped.

以上説明したようにこの発明によれば、燃料水素の供給圧力を周辺技術に相応して安全な圧力に調整することにより、燃料水素供給基地を随所に設置可能となり、燃料水素供給側と水素吸蔵合金ボンベとの接続、あるいは水素吸蔵合金ボンベと燃料水素の消費側との接続がクイックリーに行うことができ、暴発の防止効果も得られ、燃料水素の水素吸蔵合金ボンベへの充填が効率よく行われる。   As described above, according to the present invention, the fuel hydrogen supply base can be installed everywhere by adjusting the fuel hydrogen supply pressure to a safe pressure corresponding to the surrounding technology, and the fuel hydrogen supply side and the hydrogen storage side can be installed. The connection to the alloy cylinder or the connection between the hydrogen storage alloy cylinder and the fuel hydrogen consumption side can be done quickly and the effect of preventing the explosion is obtained, and the hydrogen storage alloy cylinder is efficiently filled with fuel hydrogen. Done.
