[0029] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.
[0030] In the description of the embodiments of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Among them, "fixed connection" means that the two are connected to each other and the relative position relationship after the connection remains unchanged.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.
[0032] At present, due to the volatility and intermittency of new energy such as wind power and photovoltaics, and with the rapid development of clean energy, there is an urgent need for large-scale energy storage technology.
[0033] Compressed gas energy storage, as a large-scale energy storage method with great potential, currently faces a series of problems such as high cost and low efficiency. The cost of the gas storage system accounts for more than 30% of the construction cost of the compressed gas energy storage power station, and there is a problem of pressure changes in the gas storage system during storage and release. The non-constant pressure gas storage system is not conducive to improving the efficiency of the compressed gas energy storage power station. Therefore, the foldable constant pressure gas supply device is the key to the construction of the compressed gas energy storage power station.
[0034] In the prior art, an underwater foldable constant-pressure air supply device is generally used. Specifically, it is a flexible airbag arranged underwater. The airbag is arranged underwater, and the pressure inside the airbag is kept constant by the pressure of the water. The application scenarios of this method are limited, and water pressure must be used underwater. In addition, the location of the equipment underwater is not conducive to subsequent maintenance.
[0035] To solve the above technical problems, please refer to Figures 1 to 4 The present application provides a foldable constant-pressure air supply device 100, which has a wide range of application scenarios and no special requirements.
[0036] For details, please refer to Figure 1 and Figure 2 The foldable constant-pressure gas supply device 100 may include a gas storage tank 110 and a heating element. The gas storage tank 110 may include a memory alloy peripheral wall 111, a bottom wall 112 and a top cover 113. The memory alloy peripheral wall 111, the bottom wall 112 and the top cover 113 define the internal space of the gas storage tank 110 and isolate the internal space of the gas storage tank 110 from the outside world. The bottom wall 112 and the top cover 113 are arranged opposite to each other. One end of the memory alloy peripheral wall 111 is connected to the bottom wall 112, and the other end is connected to the top cover 113, and is arranged around the bottom wall 112 and the top cover 113. A gas delivery port 1131 is provided on the top cover 113. The gas delivery port 1131 is used to transport and input gas between the gas storage tank 110 and the outside world.
[0037] The bottom wall 112 and the top cover 113 may be made of metal, resin, plastic, rubber, carbon fiber, or composite materials; specifically, the materials may be selected according to the type of gas in the gas storage tank 110 .
[0038] The gas delivery port 1131 may include a conveying port and an input port, or the gas delivery port 1131 may serve as both a conveying port and an input port. The conveying port is used to convey the gas inside the gas tank 110 to the expansion machine outside the gas tank 110 to drive the generator to generate electricity; the input port is used to input the high-pressure gas compressed by the compressor outside the gas tank 110 into the gas tank 110.
[0039] Memory alloy is a martensitic phase change alloy with regular atomic arrangement and volume change of less than 0.5%. This alloy will deform under the action of external force, and when the external force is removed, it can restore its original shape under certain temperature conditions.
[0040] The memory alloy peripheral wall 111 provided in the present application is made of a memory alloy. The memory alloy peripheral wall 111 has a first state (for example, Figure 4When the memory alloy peripheral wall 111 is in the first state, the volume of the gas storage tank 110 is the first volume; the memory alloy peripheral wall 111 has a second state in an environment lower than the first temperature. When the memory alloy peripheral wall 111 is in the second state (for example Figure 3 ), when the state of the memory alloy peripheral wall 111 is shown in , the maximum volume of the gas storage tank 110 is the second volume; wherein the second volume is greater than the first volume.
[0041] Specifically, the memory alloy peripheral wall 111 has plasticity in an environment below the first temperature, and can be stretched or compressed, wherein the length of the memory alloy peripheral wall 111 in the first state is less than the maximum length of the memory alloy peripheral wall 111 in the second state.
[0042] For example, see Figure 3 and Figure 4 The memory alloy peripheral wall 111 is formed into a bellows structure. When the memory alloy is in the first state, the distance between the wave crest and the wave trough is a first distance; the first distance is greater than the maximum distance between the wave crest and the wave trough of the memory alloy peripheral wall 111 in the second state. That is, after the memory alloy peripheral wall 111 is heated to the first temperature, the memory alloy peripheral wall 111 will shrink and fold, reducing the volume of the gas storage tank 110.
[0043] The heating element is located outside the gas storage tank 110 , and is used to heat the peripheral wall 111 of the memory alloy.
[0044] To summarize, taking the case where the gas storage tank 110 is filled with gas as an example, the gas storage tank 110 then delivers gas to an external expander, the gas in the gas storage chamber is reduced, the air pressure drops, and the heating element heats the memory alloy peripheral wall 111, so that the volume of the gas storage tank 110 becomes smaller, thereby ensuring that the air pressure inside the gas storage chamber remains unchanged; when the external compressor delivers gas to the inside of the gas storage tank 110, the heating element does not work, the ambient temperature of the memory alloy peripheral wall 111 is lower than the first temperature, and the volume of the gas storage tank 110 increases under the filling of gas, thereby ensuring that the volume of the gas storage tank 110 remains unchanged, thereby ensuring that the pressure of the gas storage tank 110 is constant during use.
[0045] In this way, the foldable constant-pressure air supply device 100 provided by the present application has no special requirements for the use environment compared with the underwater airbag in the prior art and can adapt to more application scenarios.
[0046] In some embodiments of this application, please refer to Figure 1 and Figure 2The heating element may include a heating ring 141, which is disposed on the outer side of the memory alloy peripheral wall 111. Therefore, when the gas storage tank 110 discharges gas to the outside, the surrounding environment of the memory alloy peripheral wall 111 is heated by the heating ring 141. When the ambient temperature exceeds the first temperature, the memory alloy peripheral wall 111 is deformed, so that the volume of the gas storage tank 110 becomes smaller, thereby ensuring the constant gas pressure in the gas storage tank 110.
[0047] In some embodiments of this application, please refer to Figure 1 , and refer to Figure 3 and Figure 4 The heating element may further include a track 142 and an electrically controlled pulley 143 . The track 142 is disposed on the outer side of the memory alloy peripheral wall 111 . The track 142 extends from the bottom wall 112 toward the top cover 113 . The heating ring 141 slidably cooperates with the track 142 through the electrically controlled pulley 143 .
[0048] It should be noted that, since the volume of the memory alloy peripheral wall 111 will change, the heating ring 141 needs to move in coordination with the deformation of the memory alloy peripheral wall 111. When the volume of the gas storage tank 110 needs to be reduced, the heating ring 141 is arranged around the circumferential outer side of the memory alloy peripheral wall 111. By setting a track 142 and an electrically controlled pulley 143, the heating ring 141 can slide along the axial direction of the memory alloy peripheral wall 111 to heat different parts of the memory alloy peripheral wall 111, so that the heated part and the heated part can be restored to the first state.
[0049] Specifically, the heating ring 141 is initially located close to the bottom wall 112 (eg Figure 3 As shown in FIG. 1 , when the gas storage tank 110 discharges gas, the heating ring 141 heats the memory alloy peripheral wall 111, and the memory alloy peripheral wall 111 deforms to reduce the volume of the gas storage tank 110. At this time, the heating ring 141 moves toward the top cover 113 (for example, Figure 4 As shown in the figure, the deformed memory alloy peripheral wall 111 continues to be heated so that part of the memory alloy peripheral wall 111 returns to the first state. In this way, the deformation of the memory alloy peripheral wall 111 is controlled by setting a movable heating ring 141 to meet the needs of the gas storage tank 110 to discharge gas of different volumes. The foldable constant-pressure gas supply device 100 provided in the present application can achieve a constant pressure inside the gas storage tank 110.
[0050] Therefore, the track 142 and the electrically controlled pulley 143 are provided to ensure the stability of the heating ring 141 during movement, thereby preventing the heating ring 141 from shaking and colliding with the memory alloy peripheral wall 111 .
[0051] In some embodiments of this application, please continue to refer to Figure 3 and Figure 4 The heating element may further include a connecting rod 144, one end of the connecting rod 144 is connected to the heating ring 141, and the other end is connected to the electrically controlled pulley 143. It should be noted that the heating ring 141 generally cannot be directly slidably connected to the track 142, and the sliding connection with the track 142 is achieved by setting the connecting rod 144 and the electrically controlled pulley 143.
[0052] In some embodiments of this application, please continue Figure 1 The foldable constant pressure air supply device 100 may also include a pressure sensor 150, which is located at the air delivery port 1131. The pressure sensor 150 is used to detect the air pressure at the air delivery port 1131, so as to determine the volume change of the gas storage tank 110, so as to determine the length of the memory alloy peripheral wall 111 that needs to be heated, and heat this part of the memory alloy peripheral wall 111 through the heating ring 141.
[0053] Please continue to refer to some embodiments of this application. Figure 2 The foldable constant-pressure air supply device 100 may further include a heating source 160 and a heat pipe. The heating source 160 is connected to the heating element through the heat pipe. The heat pipe transports the heat storage medium in the heating source 160 to the heating element to heat the heating element.
[0054] Among them, the heating source 160 may include a heating tube 161, which heats the heat storage medium inside the heating source 160. The heating tube 161 may use an electric heating wire or industrial waste heat to heat the heat storage medium. The heat storage medium may be water, heat transfer oil, etc.
[0055] Furthermore, the foldable constant-pressure air supply device 100 may also include a pump 175 , which is disposed on the heat-conducting pipe and provides power for the movement of the heat storage medium.
[0056] Furthermore, the foldable constant-pressure air supply device 100 may also include a valve, which is disposed on the heat-conducting pipe, and the heat-conducting pipe is turned on and off by setting the valve.
[0057] Furthermore, the heat pipe may include an input pipe 176 and an output pipe 177, wherein the input pipe 176 is used to transport the heat storage medium in the heating source 160 to the heating element, and the output pipe 177 is used to transport the heat storage medium flowing through the heating element back to the heating source 160, thereby forming a circulation of the heat storage medium.
[0058] In a specific implementation process, the valve may include a first valve 171 and a second valve 172 , wherein the first valve 171 is disposed on an input pipe 176 , and the second valve 172 is disposed on an output pipe 177 .
[0059] In some embodiments of the present application, the foldable constant pressure air supply device 100 may further include a controller, which is electrically connected to the electric control pulley 143, the pressure sensor 150, and the heating element. Specifically, the pressure sensor 150 transmits the detected air pressure of the air delivery port 1131 to the controller, and the controller gives instructions for the electric control pulley 143 to move and stop according to the signal, and gives instructions for the heating element to heat.
