For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0060] In the description of the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include the first feature being in direct contact with the second feature, or may include the first feature being in contact with the second feature through another feature between them instead of being in direct contact.

A first feature being "below", "below" and "below" a second feature includes the first feature being directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0061] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0062] like Figure 1-Figure 10 As shown, the present invention provides an explosion-proof device, including a main body support frame 1, a receiving support frame 2, a linkage assembly 3, a detection plate 4 and a release assembly 5. Among them, the receiving support frame 2 is movably connected to the main body support frame 1, and has a retracted state and an expanded state. The receiving cavity 21 of the receiving support frame 2 contains fire extinguishing powder 22. The linkage assembly 3 is arranged on the main body support frame 1, and the detection plate 4 is connected to the linkage assembly 3. When the external airflow drives the detection plate 4 to move relative to the main body support frame 1, the detection plate 4 drives the linkage assembly 3 to move. The linkage assembly 3 can drive the receiving support frame 2 to move from the retracted state to the expanded state. When the receiving support frame 2 moves to the expanded state, the release assembly 5 can drive the fire extinguishing powder 22 to be released from the receiving support frame 2.

[0063] In the present invention, the containing bracket 2 has a folded state and an unfolded state relative to the main support frame 1. In the folded state, interference with external objects such as personnel and equipment is avoided. When an explosion occurs in the building site, the detection plate 4 can timely and reliably drive the linkage component 3 to operate through the airflow, and drive the containing bracket 2 to move to the unfolded state in time. In the unfolded state, the release component 5 drives the fire extinguishing powder 22 to be released from the containing bracket 2, so as to control and isolate the fire and ensure the safety of personnel and equipment.

[0064] Specifically, the receiving bracket 2 is rotatably connected to the main body support frame 1, the receiving bracket 2 is close to the main body support frame 1 when in the retracted state, and is spaced apart from the main body support frame 1 when in the unfolded state. The above arrangement makes the receiving bracket 2 less interfered with the outside world when in the retracted state, and can be moved to the unfolded state more efficiently, and has a larger span in the unfolded state, thereby increasing the release area of ​​the fire extinguishing powder 22, thereby more reliably controlling and isolating the fire.

[0065] More specifically, the main support frame 1 and the receiving support frame 2 are both in the shape of long strips, and the main support frame 1 is provided with two receiving supports 2, which are rotatably connected to the two ends of the main support frame 1. The above arrangement makes the receiving support frame 2 less interfered with the outside world when it is in the retracted state, and effectively increases the release area of ​​the fire extinguishing powder 22.

[0066] More specifically, two main body supports 1 are provided, and the detection plate 4 can drive the receiving brackets 2 on the two main body supports 1 to move from the retracted state to the unfolded state through the linkage assembly 3. The above arrangement further increases the release area of ​​the fire extinguishing powder 22.

[0067] In this embodiment, inside a building passage extending along a first horizontal direction, a main body support frame 1 extends along the first direction, and two main body supports 1 are fixed at two ends of a second direction at the top of the building passage, and the second direction extends horizontally, which is the width direction of the building passage, and the accommodating brackets 2 on the two main body supports 1 can move toward each other, and the main body support frame 1 and the accommodating bracket 2 have the same length, and the two accommodating brackets 2 connected to the main body support frame 1 are arranged side by side in a vertical third direction, and the first direction, the second direction and the third direction are perpendicular to each other; when the two accommodating brackets 2 connected to the main body support frame 1 move to the unfolded state, they are arranged in an X-shaped cross; in the unfolded state, the higher accommodating brackets 2 on the two main body supports 1 unfold in a V-shape, with the opening facing the detection plate 4, which is an upper release structure; in the unfolded state, the lower accommodating brackets 2 on the two main body supports 1 unfold in a V-shape, with the opening facing away from the detection plate 4, which is a lower release structure, and the fire extinguishing powder 22 in the accommodating bracket 2 is a conventional material in the field, which will not be repeated here.

[0068] In other embodiments, the accommodating bracket 2 can also be slidably connected to the main body frame 1. The accommodating bracket 2 is close to the main body frame 1 when in the folded state. The accommodating bracket 2 is parallel to and spaced apart from the main body frame 1 when in the unfolded state. The fire extinguishing powder 22 can be sprinkled when moving to the unfolded state, or the fire extinguishing powder 22 can be gradually sprinkled in the process of moving from the folded state to the unfolded state.

[0069] Specifically, the linkage assembly 3 includes a pushing block 31, an elastic member 32 and a transmission mechanism 33. The main support frame 1 is provided with a blowing channel 11, and the two ends of the blowing channel 11 are respectively an inlet end and an outlet end, the inlet end is connected to the outside through an inlet 111, and the outlet end is connected to the outside through an outlet 112, the pushing block 31 is slidably arranged in the blowing channel 11, and when the pushing block 31 moves toward the outlet end, the airflow blown out of the outlet 112 of the blowing channel 11 can drive the accommodating bracket 2 to move from the retracted state to the unfolded state, the elastic member 32 is arranged on the main support frame 1, and is configured to drive the pushing block 31 to stop at the inlet end of the blowing channel 11, and the detection plate 4 is connected to the main support frame 1 through the transmission mechanism 33, and when the external airflow drives the detection plate 4 to move relative to the main support frame 1, the transmission mechanism 33 can drive the pushing block 31 to move toward the outlet end of the blowing channel 11. The accommodating bracket 2 is blown by the airflow, so that the movement of the accommodating bracket 2 is more stable and reliable.

[0070] More specifically, the transmission mechanism 33 includes a transmission frame 331, a liquid storage tube 332 and a pushing rod 333. The transmission frame 331 is connected to the detection plate 4, the main support frame 1 is provided with a transition chamber 12, the inner cavity of the liquid storage tube 332 is connected to the transition chamber 12, the air blowing channel 11 is connected to the transition chamber 12 through the inlet 111, and one end of the pushing rod 333 is connected to the transmission frame 331, and the other end is slidably arranged in the liquid storage tube 332. The above arrangement drives the pushing block 31 through the liquid in the liquid storage tube 332 and the transition chamber 12, which is more stable and reliable.

[0071] In this embodiment, the elastic member 32 is a spring, which is located in the blowing channel 11 and is sandwiched between the outlet end and the pushing block 31. In other embodiments, the elastic member 32 may also be an elastic rubber rod or the like. In other embodiments, the elastic member 32 may also be located in the transition chamber 12, and is respectively connected to the pushing block 31 and the main body support frame 1. The two receiving brackets 2 on the main body support frame 1 are respectively provided with a blowing channel 11, and the inlets 111 of the two blowing channels 11 are both connected to the same transition chamber 12. One end of the receiving bracket 2 is rotatably connected to the main body support frame 1, and the outlet 112 of the blowing channel 11 is directly opposite to the other end of the receiving bracket 2.

[0072] In other embodiments, the linkage assembly 3 may also include only a pushing block 31, an elastic member 32 and a transmission mechanism 33. The transmission mechanism 33 is a single rod-shaped structure or a connecting rod structure, which is connected to the pushing block 31 and directly drives the pushing block 31 to slide in the blowing channel 11.

[0073] Specifically, the transmission mechanism 33 further includes a liquid guide tube 334, one end of which is connected to the liquid storage tube 332, and the other end of which is connected to the transition chamber 12. By providing the liquid guide tube 334, the connection between the liquid storage tube 332 and the transition chamber 12 is more reliable.

[0074] More specifically, the explosion-proof device further comprises an auxiliary support frame 6, which is fixedly arranged relative to the main support frame 1, the detection plate 4 is rotatably connected to the auxiliary support frame 6, the transmission frame 331 comprises a swing rod 3311 and a connecting frame body 3312, one end of the swing rod 3311 is rotatably connected to the detection plate 4, and the other end is rotatably connected to the connecting frame body 3312, and the connecting frame body 3312 is fixedly connected to the pushing rod 333. The above arrangement makes the movement of the detection plate 4 more stable and reliable.

[0075] In this embodiment, the auxiliary support frame 6 is fixed to the top of the building passage, the top of the detection plate 4 is rotatably connected to the bottom of the auxiliary support frame 6, and the plate surface is perpendicular to the first direction in the free state. One end of the swing rod 3311 is rotatably connected to the bottom of the detection plate 4, and the other end is rotatably connected to the connecting frame 3312. The connecting frame 3312 is connected to two pushing rods 333, each pushing rod 333 is configured with a liquid storage tube 332, and each liquid storage tube 332 is connected to a main support frame 1 through a liquid guide tube 334. The mutually connected pushing rods 333 and liquid storage tubes 33 2 and the liquid guide tube 334 are coaxially arranged and extend along the first direction. The diameter of the liquid storage tube 332 is larger than that of the pushing rod 333 and the liquid guide tube 334. The liquid storage tube 332, the liquid guide tube 334 and the transition chamber 12 store oil. When the pushing rod 333 pushes the oil in the liquid storage tube 332, the oil in the transition chamber 12 pushes the pushing block 31 to move toward the outlet end of the blowing channel 11. The swing rod 3311 and the rotating shaft of the connecting frame 3312 are provided with a torsion spring, so that in a normal state, the swing rod 3311 can stop the detection plate 4 in a state perpendicular to the first direction.

[0076] In other embodiments, the transmission frame 331 may also only include the connecting frame body 3312, and the detection plate 4 is directly fixedly connected to the connecting frame body 3312, and moves horizontally when impacted by the explosion airflow.

[0077] Specifically, the release assembly 5 includes an electronic igniter 51, a detection sensor 52 and an explosive body 53. The electronic igniter 51 is arranged in the accommodating cavity 21, the detection sensor 52 is arranged on the main body support frame 1, and is configured to detect the state position of the accommodating support frame 2 relative to the main body support frame 1, and the explosive body 53 is arranged in the accommodating cavity 21. When the detection sensor 52 detects that the accommodating support frame 2 is in the unfolded state, the electronic igniter 51 is controlled by the controller to ignite the explosive body 53, and when the explosive body 53 explodes, the fire extinguishing powder 22 is driven to be released from the accommodating support frame 2. The above arrangement enables the release assembly 5 to release the fire extinguishing powder 22 from the accommodating support frame 2 in a timely and efficient manner.

[0078] In this embodiment, the detection sensor 52 is an angle sensor, which is arranged at the rotation axis of the accommodating bracket 2 and the main support frame 1. The opening of the accommodating chamber 21 of the accommodating bracket 2 faces downward, and a film is laid at the opening. An explosive body 53 is piled up at one end of the accommodating chamber 21 in the length direction. The explosive body 53 is a compressed explosive piled in a block shape. The electronic igniter 51 is set close to it. When the detection sensor 52 detects that the accommodating bracket 2 is in the expanded state, it sends a signal to the controller. After receiving the signal, the controller controls the electronic igniter 51 to ignite the explosive body 53. When the explosive body 53 explodes, it breaks through the film at the opening of the accommodating chamber 21, so that the fire extinguishing powder 22 in the accommodating chamber 21 can be scattered under the action of its own gravity. Among them, the detection sensor 52, the controller and the electronic igniter 51 are conventional components in the prior art, and their specific circuit connection relationship and working principle are prior art, which will not be repeated here.

[0079] In other embodiments, when the receiving bracket 2 is slidably connected to the main body bracket 1 , the detection sensor 52 is a position sensor that can detect the distance between the receiving bracket 2 and the main body bracket 1 .

[0080] Specifically, the explosion-proof device further comprises a lighting fixture 7, which is arranged on the main support frame 1. The above arrangement enables the lighting fixture 7 to have an explosion-proof function, thereby ensuring the safe operation of the lighting fixture 7.

[0081] In this embodiment, the lighting fixture 7 is an LED lamp. In other embodiments, the lighting fixture 7 can also be other types of lamps, which are not limited here.

[0082] The present invention also provides an explosion-proof method, using the above-mentioned explosion-proof device, comprising the following steps:

[0083] Step 1: When an explosion occurs, the explosion airflow impacts the detection plate 4.

[0084] Step 2: The detection board 4 drives the linkage component 3 to move.

[0085] Step 3: The linkage assembly 3 drives the accommodating bracket 2 to move from the retracted state to the unfolded state.

[0086] Step 4: the release component 5 drives the fire extinguishing powder 22 to be released from the containing bracket 2.

[0087] In the explosion-proof method of the present invention, the containing bracket 2 has a folded state and an unfolded state relative to the main support frame 1. In the folded state, interference with external objects such as personnel and equipment is avoided. When an explosion occurs in the building site, the detection plate 4 can timely and reliably drive the linkage component 3 to operate through the airflow, and drive the containing bracket 2 to move to the unfolded state in time. In the unfolded state, the release component 5 drives the fire extinguishing powder 22 to be released from the containing bracket 2, so as to control and isolate the fire and ensure the safety of personnel and equipment.

[0088] Based on the specific structure of explosion-proof equipment, the specific steps of the explosion-proof method are described below:

[0089] S1. Install and arrange explosion-proof equipment on the top of explosion-proof buildings or building passages.

[0090] In this step, when laying out the explosion-proof equipment, the detection plate 4 is arranged toward the side with explosion risk, and the accommodating bracket 2 is in a retracted state.

[0091] S2. When an explosion occurs, the explosion airflow impacts the detection plate 4.

[0092] In this step, when an explosion occurs inside the building, the explosion airflow impacts the detection plate 4, and the detection plate 4 swings relative to the auxiliary support frame 6 after being subjected to the force.

[0093] S3, the detection board 4 drives the linkage component 3 to move.

[0094] In this step, the detection plate 4 pushes the connecting frame 3312 to translate through the rocker rod 3311 during the swinging process. When the connecting frame 3312 translates, it simultaneously pushes the two pushing rods 333, thereby squeezing the oil in the two liquid storage tubes 332. The oil flows in the interconnected liquid storage tubes 332, the liquid guide tube 334 and the transition chamber 12, and finally pushes the pushing block 31 to move toward the outlet end of the blowing channel 11.

[0095] S4, the linkage assembly 3 drives the accommodating bracket 2 to move from the retracted state to the unfolded state.

[0096] In this step, when the pushing block 31 moves toward the outlet end of the blowing channel 11, the gas inside the blowing channel 11 is compressed, and an airflow is blown out from the outlet 112 of the blowing channel 11, and the airflow blows the accommodating bracket 2 from the retracted state to the unfolded state.

[0097] S5 , the release component 5 drives the fire extinguishing powder 22 to be released from the receiving bracket 2 .

[0098] In this step, when the detection sensor 52 detects that the accommodating bracket 2 is in the expanded state, it sends a signal to the controller. After receiving the signal, the controller controls the electronic lighter 51 to ignite the explosive body 53. When the explosive body 53 explodes, it breaks through the film at the opening of the accommodating chamber 21, so that the fire extinguishing powder 22 in the accommodating chamber 21 can be scattered under the action of its own gravity.

[0099] S6. The fire extinguishing powder 22 in the lower release structure is sprinkled first, and the fire extinguishing powder 22 in the upper release structure is sprinkled later.

[0100] In this step, the fire extinguishing powder 22 in the lower release structure is sprinkled first, forming a V-shaped fire extinguishing powder curtain inside the building passage, increasing the contact area with the flame in the passage, and the fire extinguishing powder 22 in the lower release structure is sprinkled and released to form a low-pressure area in the passage. The fire extinguishing powder 22 in the upper release structure is sprinkled and released later, so that the fire extinguishing powder 22 in the upper release structure is released in the direction of the explosion, further controlling the fire, and the fire protection equipment forms a continuous fire extinguishing powder curtain on the upper side of the building passage to isolate the fire.

[0101] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here.
