As will be appreciated by those skilled in the art, the relative positional relationship between the bladder 106 and the gas bladder 102 is not limited to the bladder 106 being located above the gas bladder 102 as mentioned above, but may be in other directions, such as in a horizontal direction, where the bladder 106 is located on one side of the gas bladder 102 (see fig. 3).
Along the horizontal direction, the liquid bag 106 is arranged at one side of the gas bag 102, and according to the pascal principle, liquid in the liquid storage cavity 107 still can squeeze the side wall of the liquid bag 106, and the liquid bag 106 can apply pressure to the gas bag 102, so that the gas in the gas storage cavity 103 can be pressurized.
Referring to fig. 4, in an embodiment of the present application, the gas storage device serving for country plain vibration further includes a guide rail 114 assembly disposed in the first cavity, the guide rail 114 assembly includes a guide rail 114 and rollers 115 in rolling fit with the guide rail 114, the liquid bladder 106 and the gas bladder 102 are respectively connected with the rollers 115, the guide rail 114 assembly can guide the volume change of the liquid storage cavity 107 and the volume change of the gas storage cavity 103, thereby ensuring that the change of the gas storage cavity 103 and the change of the liquid storage cavity 107 are stable, and ensuring production safety.
Referring to fig. 1, in one embodiment of the present application, the gas storage device serving the country plain is further provided with a gas filter 116, an inlet of the gas filter 116 is communicated with the gas outlet 105, and the gas filter 116 can filter the gas, thereby avoiding impurities from entering the pipeline.
Referring to fig. 5, in one embodiment of the present application, the gas storage device serving the country plain is further provided with a waterproof case 117, the waterproof case 117 is formed by casting waterproof concrete, an installation cavity is provided inside the waterproof case 117, and the protective case 101 is provided in the installation cavity.
By providing the waterproof case 117, the humidity of the installation cavity and the humidity in the first cavity can be reduced, and the life of the protective case 101 and the members in the first cavity can be improved.
Referring to fig. 5, in one embodiment of the present application, the outer wall of protective shell 101 encloses a filling cavity with the inner wall of waterproof shell 117, and the filling cavity is filled with buffer filler 118.
By providing the buffer filler 118 in the filled cavity, the impact of the external environment on the components in the first cavity can be reduced, thereby ensuring production safety. Buffer filling 118 may be a building material such as sand.
In summary, the gas storage device has the characteristics of low construction cost, convenient maintenance and safe use, and after the gas airbag 102 is inflated, gas delivery can be realized by utilizing liquid gravity, and the pipeline is not required to be pressurized by the gas booster pump, so that the gas storage device can adapt to the energy environment of remote areas and reduce unnecessary energy consumption.
The foregoing is merely an embodiment of the present application and is not intended to limit the present application. Various modifications and changes may be made to the present application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc. which are within the spirit and principles of the present application are intended to be included within the scope of the claims of the present application.
