[0031] like Figs. 1-3As shown, this application provides a high-pressure medium-triggered release device, which is disposed on a high-pressure container 1. Specifically, the release device includes a sealing body 2, an excitation body 4, and an excitation signal line 5. The high-pressure container 1 has a cavity containing a high-pressure medium, including at least one of high-pressure air, nitrogen, carbon dioxide, hydrogen, or helium. A pressure vessel flow channel 7 is provided on the side wall of the high-pressure container 1, and this flow channel 7 connects the cavity to the outside of the high-pressure container 1. The pressure vessel flow channel 7 is preferably arranged horizontally. The sealing body 2 is disposed within the pressure vessel flow channel 7 and seals the flow channel 7, thereby blocking the connection between the cavity and the outside of the high-pressure container 1. The sealing body 2 is used to block the flow and release of the high-pressure medium. The sealing body 2 is disposed between the pressure vessel flow channel 7 and the fastening channel 8 of the fastening component 6, blocking the connection between the pressure vessel and the outside. The excitation signal line 5 is used to send an excitation signal to the excited state and can be led out from a pre-reserved through hole in the fastening component 6. The excitation body 4 is disposed within the sealing body 2, and after excitation, it breaks the sealing body 2. One end of the excitation signal line 5 is connected to the excitation body 4, and the other end extends to the outside of the high-pressure container 1 and connects to the control system, thereby allowing the control system to control the excitation as a whole. Specifically, the control system transmits a current signal to the excitation body 4 through the excitation signal line 5, triggering a chemical reaction and thermal melting reaction in the excitation body 4, causing the seal to break and forming a flow channel to achieve excitation. The high-pressure medium trigger release device provided by this invention achieves excitation and release by designing the high-pressure container and the release device to cooperate, thus propelling the load forward. This is simple, reliable, easy to operate, provides accurate release pressure, and the release process is fast and controllable. It can be widely used in fields such as gas explosion, gas-filled rescue, and load propulsion, and has broad market application prospects.

[0032] In this application, the release device is installed in conjunction with a pressure vessel to store high-pressure media. The pressure vessel has a connection port for releasing the high-pressure media through a flow channel. After the high-pressure media is released from the flow channel, it performs work externally, propelling the load forward. The shape of the sealing body and the size of the flow channel of the release device must be matched with the flow channel of the pressure vessel. This application provides a high-pressure media trigger release device, mainly used for releasing media from within a high-pressure vessel. Its size, shape, and many other parameters are determined by the vessel; therefore, the materials and strength parameters used must be compatible with the pressure vessel.

[0033] Preferably, in combination with the above schemes, such as Figs. 1-2 As shown, the exciter 4 is disposed inside the sealed body 2 and is used to excite the sealed body to break after receiving a signal. Furthermore, the sealed body 2 is provided with a reserved hole 9, and the excitation signal line 5 is connected to the exciter 4 inside the sealed body 2. The other end of the excitation signal line 5 extends out of the high-pressure vessel 1 along the reserved hole 9, thereby connecting with the controller of the control system to realize signal control.

[0034] Preferably, in combination with the above schemes, such as Figs. 1-2 As shown, the high-pressure medium trigger release device provided in this application also includes a fastening component 6, which has a hollow fastening channel 8 for fastening the sealing body within the pressure vessel flow channel 7, with the fastening channel 8 remaining in the middle. Further, the fastening component 6 is disposed on the high-pressure vessel 1 and extends at least partially into the pressure vessel flow channel 7, thereby connecting the fastening channel 8 with the pressure vessel flow channel 7. The sealing body 2 is sealed at the junction of the fastening channel 8 and the pressure vessel flow channel 7, i.e., between the fastening channel 8 and the pressure vessel flow channel 7, achieving a two-stage connection. Specifically, after receiving an excitation signal, the excitation body 4 triggers an excitation action, causing the sealing body 2 to break open, thereby connecting the pressure vessel flow channel 7 with the fastening channel 8, and allowing the high-pressure medium to be released from the pressure vessel flow channel 7 and the fastening channel 8, performing work externally and propelling the load forward.

[0035] like Figs. 1-2 As shown, the inner side of the fastening component 6 in this application is fastened to the inner wall of the pressure vessel flow channel 7. Before the seal 2 ruptures, the fastening component 6 can withstand the pressure transmitted by the high-pressure medium. During and after rupture, it can withstand the pressure brought by the actuation of the excitation body and the flow of the medium. The front end of the fastening component 6 fastens the seal to the pressure vessel. When the pressure vessel is sealed, the force distribution of the seal 2 becomes more reasonable, and it can withstand the pressure transmitted by the high-pressure medium. The outer side of the annular wall of the fastening component 6 is located inside the actuation mechanism. The piston is pushed by the flow of the high-pressure medium to control the opening and closing of the flow channel of the release port device. A through hole is reserved on the fastening component 6 as a channel for the excitation signal line to be led out. It is located inside the fastening device, and the size and shape of the through hole match the excitation signal line.

[0036] Preferably, in combination with the above schemes, such as Figs. 1-2 As shown, the high-pressure medium-triggered release device provided in this application also includes a protective membrane 3, which is disposed on the fastening channel 8 and seals the fastening channel 8. The inner side of the fastening component 6 is fixedly connected to the side wall of the pressure vessel flow channel 7; the front side wall of the fastening component 6 is fixedly connected to the outer side wall of the high-pressure vessel 1; one outer end of the fastening component 6 is disposed on the actuating mechanism and can push the piston of the actuating mechanism through the flow of the high-pressure medium, thereby controlling the opening and closing of the flow channel of the release port device.

[0037] Preferably, in combination with the above schemes, such as Figs. 1-2As shown, in this embodiment, the protective film 3 is a plastic film with a thickness H of less than 0.5 mm, i.e., 0 mm < plastic film thickness H < 0.5 mm. Within this thickness range, the plastic film can effectively match the pressure breakthrough flow of the high-pressure medium to drive the piston. Furthermore, the inner side of the fastening component 6 is fixedly connected to the side wall of the pressure vessel flow channel 7 by threads, snaps, or riveting; the fastening component 6 has a through hole so that the excitation signal line 5 can pass through the through hole and extend to the outside of the high-pressure vessel 1. The plastic film is used to cover the flow channel of the fastening device and the through hole of the fastening component 6, protecting the through hole of the fastening component 6 and the excitation signal line, keeping the channel clean. The protective film does not have high strength and does not affect the release of the high-pressure medium from the flow channel.

[0038] Preferably, in combination with the above schemes, such as Figs. 1-2 As shown, the fastening channel 8 is sized and shaped according to the requirements of the pressure vessel, and can be circular, elliptical, square, irregularly shaped, or a combination of multiple shapes. After the seal 2 ruptures, a normal flow channel can be formed. The cross-section of the pressure vessel flow channel 7 is the same as the external shape of the seal 2, and the cross-section of the pressure vessel flow channel 7 and the external shape of the seal 2 are circular, elliptical, square, or regular polygonal.

[0039] Preferably, in combination with the above schemes, such as Figs. 1-2 As shown, the sealing body 2 needs to possess a certain strength, primarily considering its pressure resistance to meet the pressure of the high-pressure medium in the container. It can be circular, oriented, or irregularly shaped, and its size can range from a few square millimeters to tens of square centimeters. The material of the sealing body 2 is a polymer composite material, a metal material, or a combination of metal and polymer materials. Furthermore, the polymer composite material is PEEK or ABS; the metal is aluminum alloy or powder metallurgy stainless steel, mainly to ensure that after breakage, no residue forms in the flow channel, affecting the flow and release of the high-pressure medium.

[0040] Preferably, in combination with the above schemes, such as Figs. 1-2 As shown, the exciter 4 is disposed inside the sealed body 2, with an excitation signal line leading out through a pre-reserved through hole to the fastening component 6. In use, receiving the excitation signal causes the exciter to actuate, breaking the sealed body and connecting the pressure vessel flow channel 7 with the fastening flow channel 8, thereby triggering the release of the high-pressure medium. The exciter 4 is excited by thermal melting or thermal reaction through means including but not limited to electrical energy, magnetic energy, and chemical energy; that is, the exciter 4 achieves excitation through thermal melting or thermal reaction using electrical energy, magnetic energy, or chemical energy.

Furthermore, the control system controls the triggering of each release device via a timing controller, thereby activating each timing-controlled release device.
