Description

Technical Field

[0001] The present invention relates to the technical field of civil aviation fire extinguishing and explosion-proof supporting equipment, and in particular to an adaptive pressure relief turbine flame arrester for intercepting detonation particles. Background Art

[0002] With the widespread use of lithium batteries in electronic devices, fires and explosions caused by thermal runaway are becoming more common in aircraft cabins. If a lithium battery or electronic device containing a lithium battery experiences a thermal runaway fire or explosion, a protective enclosure is typically used to isolate the fire, extinguish the fire, and prevent explosions. The burning flames of lithium batteries or electronic devices containing lithium batteries in a protective box will spread randomly inside, and the explosion will produce a blast wave and a high-pressure internal environment in the protective box. Existing protective boxes generally have pressure relief ports to relieve pressure and release the energy of the blast wave, but local combustion and explosion of lithium batteries or electronic devices containing lithium batteries will produce detonation particles. The detonation particles contain toxic particulate matter, such as cobalt, nickel, manganese, cadmium, lead, mercury, lithium and other toxic metal particles. Inhalation of detonation cobalt compound particles can cause respiratory diseases (such as pneumonia, asthma), and cobalt compound particles are also carcinogenic; inhalation of detonation nickel compound particles can cause lung diseases, and nickel compound particles are also carcinogenic; inhalation of detonation manganese compound particles can damage the nervous system, leading to symptoms similar to Parkinson's disease, such as muscle tremors and movement disorders; inhalation of detonation cadmium compound particles can cause kidney damage, bone lesions, etc.; detonation particles also contain electrolyte solvents (adhering to the detonation particles) and fluoride and other harmful substances. Traditional protective boxes do not have protective structures to prevent the discharge of explosive particles. These toxic explosive particles will be discharged through the pressure relief port, causing personal injury to staff and passengers outside. Summary of the Invention

Under the action of the elastic tension of the spring, the movable valve closes the air inlet A of the cylinder bottom plate; a plurality of air inlet holes B are opened around the cylinder bottom plate B at the spring connection position, and a plurality of air outlet holes are opened on the air outlet cover plate.

[0005] In order to better implement the present invention, the cylinder bottom plate A is fixed with a turbine blade assembly located in the intercepting cylinder cavity, and the turbine blade assembly is composed of a plurality of turbine arc blades, and all the turbine arc blades of the turbine blade assembly are distributed circumferentially around the air inlet A.

[0012] Preferably, the sound-absorbing, flame-retardant and energy-absorbing material is composed of a composite of glass wool, carbon fiber reinforced resin-based composite material and ceramic fiber.

[0013] An explosion-proof protective box composed of an adaptive pressure relief turbine flame arrester comprises a box body and a box cover with a closure cover fitted on the box body. A pressure relief port is provided on the box cover and / or the box body, and the pressure relief port cooperates with the adaptive pressure relief turbine flame arrester to be installed.

[0014] Compared with the prior art, the present invention has the following advantages and beneficial effects: (1) The present invention is mainly installed at the pressure relief port of an explosion-proof protective box, and provides a solution for fire extinguishing, pressure relief and interception of detonation particles for combustion and explosion caused by thermal runaway of lithium batteries or electronic equipment containing lithium batteries in the explosion-proof protective box. The explosion airflow is divided and extinguished through the air inlet B of the air inlet cylinder, and then the shock wave effect generated by the explosion is divided and absorbed by the various explosion wave energy absorbing parts in the air inlet cylinder; then the explosion airflow enters the interception cylinder cavity of the turbine interception cylinder through the air inlet A to intercept the detonation particles. The detonation particles are deposited on the circumference of the bottom of the interception cylinder cavity for centralized treatment, and the gas is discharged through various air outlets.

[0015] (2) The turbine interception cylinder of the present invention is equipped with a turbine blade assembly composed of turbine arc blades that guide the wind flow in a spiral manner.

When the lithium battery or electronic equipment containing a lithium battery inside the explosion-proof protective box thermally runs away and causes combustion and explosion, the explosive air flow enters from the air intake pipe and impacts the movable valve, and the movable valve moves upward. The movable valve pushes the telescopic rod to contract in the sleeve, and the movable valve no longer closes the air inlet A, and the air inlet A is opened. The movable valve plays the role of adaptive pressure relief and exhaust. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] Below in conjunction with embodiment, the present invention is described in further detail: Example

[0021] like Figures 1 to 7As shown, an adaptive pressure relief turbine flame arrester for intercepting detonation particles comprises an air outlet cover plate 1, a turbine interception cylinder 2 and an air inlet cylinder 3. The turbine interception cylinder 2 has an interception cylinder cavity for intercepting and storing detonation particles (see Figure 6 The interception cylinder cavity is the inner cavity of the turbine interception cylinder 2. The bottom of the interception cylinder cavity of the turbine interception cylinder 2 is the cylinder bottom plate A21. The center of the cylinder bottom plate A21 has an air inlet hole A22 (the air inlet hole A22 is the hole for the explosion airflow to enter). The air outlet cover 1 covers the turbine interception cylinder 2 and closes the top of the interception cylinder cavity. The top of the air inlet cylinder 3 is sealed and connected to the bottom of the cylinder bottom plate A21 (see Figure 5 The air intake cylinder 3 is sealed and connected to the bottom of the turbine interception cylinder 2). Preferably, the top of the air intake cylinder 3 has an outward-turned ear plate B32, and the ear plate B32 of the air intake cylinder 3 is fixed to the cylinder bottom plate A21 of the turbine interception cylinder 2 by screws. The cylinder bottom of the air intake cylinder 3 has a cylinder bottom plate B31, and the center of the air outlet cover plate 1 is fixed with a sleeve 5 (such as Figures 1 to 3 As shown, the top of the sleeve 5 extends through the center of the outlet cover plate 1, and the sleeve 5 is fixed to the mounting hole in the center of the outlet cover plate 1). A telescopic rod 6 is installed in the sleeve 5 for telescopic movement (the telescopic rod 6 telescopically moves within the sleeve 5). The end of the telescopic rod 6 is fixed to a movable valve 7 located in the interception cylinder chamber of the turbine interception cylinder 2 for lifting movement. A spring 8 is fixed to the center of the inner side of the cylinder bottom plate B31. The end of the spring 8 passes through the air inlet hole A22 and is connected and fixed to the movable valve 7. Figure 2 As shown, under the elastic tension of the spring 8, the movable valve 7 closes the air inlet A22 of the bottom plate 21 of the cylinder; when the lithium battery or the electronic device containing the lithium battery in the explosion-proof protective box thermal runaway causes combustion and explosion, see Figure 2 The explosive airflow enters from the air inlet holes B33 on the outer side of the air inlet cylinder 3 and impacts the movable valve 7, causing the movable valve 7 to move upward (the movable valve 7 pushes the telescopic rod 6 to move in the sleeve 5). Figure 3 As shown, the movable valve 7 no longer closes the air inlet A22, and the air inlet A22 is opened, and the movable valve 7 plays the role of adaptive pressure relief and exhaust. Figure 3Several air inlet holes B33 connected to the inner cavity of the air inlet cylinder 3 are opened on the cylinder bottom plate B31 around the connection position of the spring 8. The flame explosion airflow inside the explosion-proof protective box enters the inner cavity of the air inlet cylinder 3 through the air inlet hole B33, and then impacts the movable valve 7. Several air outlet holes 11 are opened on the air outlet cover plate 1. The air outlet holes 11 are used to discharge the gas in the interception cylinder cavity of the turbine interception cylinder 2, so as to exhaust and relieve pressure inside the explosion-proof protective box. Thermal runaway of lithium batteries or electronic devices containing lithium batteries causes combustion and explosion, and the airflow carries detonation particles into the interception cylinder cavity of the turbine interception cylinder 2 from the air inlet B33, and is then intercepted in the interception cylinder cavity of the turbine interception cylinder 2. The gas is discharged through the air outlet 11 of the air outlet cover 1, and the airflow enters the interception cylinder cavity of the turbine interception cylinder 2 from the air inlet A22 of the cylinder bottom plate A21. The speed of the airflow is slowed down and the airflow is redirected in the interception cylinder cavity of the turbine interception cylinder 2. The air outlet 11 of the air outlet cover 1 does not directly correspond to the air inlet A22. The airflow will pass through the interception cylinder cavity of the turbine interception cylinder 2 to redirect the airflow path, so that the detonation particles are intercepted and stored in the interception cylinder cavity of the turbine interception cylinder 2. The explosive airflow of the present invention enters through the air inlet B33 arranged on the outer side of the circumference of the air inlet cylinder 3 (see Figure 2 、 Figure 3 The explosive airflow enters from the outer side of the circumference of the air inlet cylinder 3 and hits the movable valve 7 in the center. When the movable valve 7 is opened, the explosive airflow enters the interception cylinder cavity of the turbine interception cylinder 2 through the air inlet hole A22. The explosive airflow will flow according to the planned path and be unloaded in the process. At the same time, the explosive airflow needs to overcome the elastic force of the spring 8 to hit the movable valve 7, and part of its energy is also dissipated). Then it enters the interior of the turbine interception cylinder 2 through the air inlet hole A22 located in the center, and then each turbine arc blade 23 guides counterclockwise or clockwise and intercepts the detonation particles, and finally is discharged through the air outlet hole 11 arranged in a circle on the air outlet cover plate 1. The flow path of the explosive airflow inside the present invention is planned and designed layer by layer, which realizes the pressure relief while gradually extinguishing the fire, absorbing energy and intercepting the detonation particles, and the protection effect is significantly improved.

[0022] In some preferred embodiments, the bottom plate A21 of the cylinder is fixed with a turbine blade assembly located in the interception cylinder cavity. The turbine blade assembly is composed of a plurality of turbine arc blades 23. All turbine arc blades 23 of the turbine blade assembly are distributed circumferentially around the air inlet A22. The turbine arc blades 23 are generally arc-shaped. The height of the turbine arc blades 23 is half the height of the cylinder cavity of the turbine interception cylinder 2. The arc direction of all turbine arc blades 23 of the turbine blade assembly is consistent. All turbine arc blades 23 of the turbine blade assembly are used to guide clockwise or counterclockwise wind flow, such as Figure 6 As shown, all turbine arc blades 23 guide the explosion airflow to move clockwise or counterclockwise. Figure 6All the turbine arc blades 23 are distributed in a counterclockwise arc shape. The detonation particles in the explosion airflow are first blocked and intercepted by each turbine arc blade 23 (after interception, they will be gradually carried by the wind flow to the bottom of the turbine interception cylinder 2 for accumulation), and then accumulated at the bottom of the interception cylinder cavity of the turbine interception cylinder 2 under the guidance of the turbine blade assembly. At the same time, under the centrifugal effect of the wind flow, the detonation particles will gradually settle on the circumference of the bottom of the interception cylinder cavity of the turbine interception cylinder 2, and can be cleaned up afterwards. After the explosion airflow is processed by intercepting the detonation particles in the interception cylinder cavity of the turbine interception cylinder 2, the gas will be discharged through the various outlet holes 11 of the outlet cover plate 11 (the aperture of the outlet hole 11 is relatively small). In some embodiments, the inner wall of the air inlet cylinder 3 is provided with a blast wave energy absorbing member, which is a wave-shaped continuous combined energy absorbing member or a convex single energy absorbing member. The blast wave absorber can be a single, raised, independent structure. Alternatively, it can be a combined, wave-like structure, forming a continuous, undulating structure protruding from the inner wall of the air intake tube 3. The blast wave absorber has a curved surface and a sound-absorbing cavity located within the curved surface. The curved surface is provided with several quenching holes, and the cavity is filled with a sound-absorbing, flame-retardant material. Preferably, the sound-absorbing, flame-retardant material is composed of a composite of glass wool, carbon fiber-reinforced resin-based composite material, and ceramic fiber. The composite material is a honeycomb structure (i.e., a porous honeycomb structure) composed primarily of glass wool (primarily responsible for sound absorption), carbon fiber-reinforced resin-based composite material (primarily responsible for energy absorption), and ceramic fiber (primarily responsible for flame retardancy). This embodiment uses the example of an adaptive pressure relief turbine flame arrester installed in correspondence with the pressure relief port of an explosion-proof protective box. When a lithium battery or electronic device containing a lithium battery experiences thermal runaway and explodes within the explosion-proof protective box, the shock wave generated by the explosion reaches the blast wave energy absorber, where it is divided and absorbed. If the flame reaches the blast wave energy absorber, it is quenched by the quenching holes. The blast wave energy absorber's sound-absorbing, energy-absorbing, and flame-retardant materials provide sound-absorbing, energy-absorbing, and flame-retardant properties. Of course, the adaptive pressure relief turbine flame arrester of the present invention can also be installed on the inner wall of the explosion-proof protective box (not at the pressure relief port). Its primary function is to extinguish fire, reduce noise, absorb energy, and provide flame retardancy, and is not used for exhaust pressure relief.

[0023] In some embodiments, the top edge of the interception cylinder cavity of the turbine interception cylinder 2 has an outward-turned ear plate A24. The ear plate A24 of the turbine interception cylinder 2 is screwed to the outlet cover plate 1. A sealing gasket 4 is also installed between the ear plate A24 and the outlet cover plate 1, and the sleeve 5 passes through the sealing gasket 4.

[0024] like Figure 1As shown, the air outlet cover plate 1 is composed of several layers of circular air outlet assemblies from the outside to the inside, and each layer of air outlet assemblies is composed of several air outlet holes 11 distributed in a circular pattern on the air outlet cover plate 1. Each layer of air outlet assemblies is composed of several air outlet holes 11 arranged in a circular pattern to form a circle of air outlet assemblies. The air outlet assemblies are concentrically arranged inside and outside, and the sizes of the air outlet holes 11 of each layer of air outlet assemblies can be the same or different.

[0025] like Figure 8 As shown, an explosion-proof protective box comprising an adaptive pressure-relief turbine flame arrester comprises a box body 9 and a box cover 10 that is secured to the box body 9. A pressure relief vent 12 is formed in the box cover 10 and / or the box body 9. The pressure relief vent 12 is adapted to accommodate the adaptive pressure-relief turbine flame arrester of the present invention. Thermal runaway of a lithium battery or electronic device containing a lithium battery within the explosion-proof protective box triggers a combustion-explosive airflow, carrying detonating particles. This combustion-explosive airflow enters the air intake 3 through the various air intake holes B33. These air intake holes B33 also serve to fragment the explosion shock wave and combustion flame, preventing larger particles from falling back into the explosion-proof protective box. The combustion-explosive airflow is then fragmented and absorbed by the explosion-induced shock wave energy absorbers within the explosion-arresting air intake 3, simultaneously extinguishing the fire. The explosion-explosive airflow then impacts the movable valve 7, causing it to rise. The telescopic rod 6 retracts into the sleeve 5, and the movable valve 7 no longer seals the air intake hole A22. Air intake hole A22 is opened, and the movable valve 7 serves as an adaptive pressure-relief exhaust device. After the air inlet A22 is opened, the explosive airflow enters the interception chamber of the turbine interception cylinder 2. The detonation particles in the explosive airflow are first blocked and intercepted by the various turbine arc blades 23 (after interception, they are gradually carried by the wind flow to the bottom of the interception chamber of the turbine interception cylinder 2 and accumulated). Then, under the guidance of the turbine blade assembly, they accumulate at the bottom of the interception chamber of the turbine interception cylinder 2. At the same time, under the centrifugal effect of the wind flow, the detonation particles are gradually deposited on the circumference of the bottom of the interception chamber of the turbine interception cylinder 2, and can be cleaned up in a centralized manner afterwards. After the explosive airflow is processed by the detonation particle interception in the interception chamber of the turbine interception cylinder 2, the gas is discharged through the various air outlets 11.

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
