Description

Technical Field

[0001] The invention belongs to the technical field of fire emergency treatment, and in particular relates to a quickly constructed fire-fighting passage. Background Art

[0002] During the rescue process of a fire in a building area, firefighters need to select fire-fighting equipment based on the type of burning items between areas.

[0003] During the firefighting process, if the fire covers the aisle that the firefighters pass through, the firefighters need to quickly extinguish the fire in the aisle area, using a push-type approach to gradually eliminate the fire source in the aisle area to avoid being covered by the fire during the return journey.

[0004] However, since the aisle was covered by the fire, the firefighters were actually covered by the fire during the fire-fighting process. Even if the firefighters were wearing fire protective clothing, the flames directly covered the firefighters as they passed through the aisle, and burning objects fell, posing a great safety hazard to the firefighters' operations.

[0005] To this end, during the fire-fighting process in the corridor, it is necessary to design a fire-fighting passage that can block fire for firefighters, and the fire-fighting passage needs to have good fire-proof performance, and the passage can be folded and retracted to a corresponding length and can be retracted and extended freely.

[0006] In response to this, various fire-fighting units have also cooperated with relevant technical personnel to develop this type of fire-fighting passage. A more mature one is the scissors-frame folding design, with fireproof cloth installed on the outside and a pulley seat set at the bottom of the scissors frame. When not in use, the fireproof cloth can be folded effectively with the scissors frame, making it convenient to push it to move in the aisle; when in use, it can be opened by two firefighters stretching it forward and backward, providing a fire shelter for firefighters when fighting fires in the aisle.

[0007] The other is a product in the experimental stage. The fireproof shed is made of fireproof fabric and is inflated with a micro high-pressure air pump, allowing it to expand and take shape quickly. It is more convenient to carry and put into use.

[0008] However, for the aisle covered by a large fire, it is usually accompanied by thick smoke, so there are considerable difficulties in laying the fire passage during the firefighting process: first, in the thick smoke, the facilities in the aisle are not clear, so in the process of the fire passage being stretched and opened, it is easy to hit the objects in the aisle, posing a safety hazard; second, in the case of the spread of the fire, there is a safety threat in the process of laying the fire passage; although the first type of fire passage has good fire isolation performance and adopts a scissor frame setting, it has the ability to prevent burning objects from falling and hitting to a certain extent, and its erection length can be changed as needed; but when it is unfolded, two firefighters are required to be located on both sides of it and pull it open in opposite directions, which is easy to hit the objects in the aisle, and under the fire coverage, there is a safety risk to the firefighters on the side covered by the fire; the second type adopts a fast inflation setting, which can be quickly erected in the fire area by firefighters in the area not covered by the fire, and it also has the ability to prevent burning objects from falling and hitting, but during the fast inflation process, due to its uncontrollable length, it is easy to hit the facilities in the aisle, thereby causing the possibility of objects falling.

[0009] Therefore, it is necessary to provide a fire-fighting passage which can be quickly set up by one person and avoid hitting the aisle facilities under the obstruction of thick smoke and fire. Summary of the invention

[0010] The purpose of the present invention is to provide a fire-fighting passage that can be quickly constructed to solve the problems existing in the prior art.

[0011] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a rapidly constructed fire-fighting passage, comprising a storage frame, roller seats are arranged on four sides of the bottom of the storage frame, a support frame is arranged on one side of the bottom of the storage frame, a handle is installed on the support frame, a suction and inflation mechanism is arranged on the support frame, a row of pipes is evenly arranged in a circumferential direction on one side of the storage frame, a collecting pipe is connected to one end of the row of pipes, an end of the collecting pipe is connected to the suction and inflation mechanism, a folding pipe is connected to one end of the row of pipes, a fireproof layer is arranged on the outside of the folding pipes, and the suction and inflation mechanism is used to inflate and inhale air into the folding pipes;

[0012] The folding tube is provided with a heat insulation layer, the heat insulation layer is provided with a support mesh layer, the support mesh layer is evenly and laterally provided with inner support frames, the bottom ends of the inner support frames are rotatably provided with walking wheels, adjacent inner support frames are rotatably connected with shear frames, and the inner support frames are provided with a heat insulation layer;

[0013] The storage frame is provided with a retracting and releasing mechanism, which is used to cooperate with the suction and air-injection mechanism to retract and release the inner support frame;

[0014] A millimeter wave radar head is arranged in the storage frame, and the millimeter wave radar head is used to emit millimeter waves and receive millimeter wave reflection feed point signals;

[0015] A control mechanism is provided on one side of the storage frame, and the control mechanism is used to receive the millimeter-wave reflection feed point signal fed by the millimeter-wave radar head in real time, analyze the distance between the storage frame and the front object, and set the control limit of the air suction and injection mechanism and the retracting and releasing mechanism according to the analysis result. When the control mechanism is manually operated, the control limit controls the degree of manual operation.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The fast-built fire-fighting passage in the present invention can be quickly built and folded by a single person standing in the aisle area not covered by the fire and simply issuing control instructions, and a millimeter-wave radar head that can penetrate thick smoke and fire for distance detection is used to detect the distance, and the executable deployment length is calculated by the module in the control mechanism, and the channel is deployed according to the executable deployment length. Therefore, it can avoid hitting the aisle facilities under the obstruction of thick smoke and fire, and solves the problems existing in the fire-fighting passage in the prior art;

[0018] In addition, the fire-fighting passage not only has the ability to resist heat, fire and heat insulation, but also has the ability to resist falling objects. Therefore, when deployed, it can effectively provide a fire barrier for firefighters, making the fire-fighting process in the aisle safer for firefighters.

[0019] In the rapidly constructed fire-fighting passage of the present invention, a control mechanism determines whether to activate the heat-driving mechanism according to the corresponding highest temperature value in the thermal image. When the heat-driving mechanism is activated, the firefighters only need to stand in the water mist coverage area of ​​the heat-driving mechanism to cool down the firefighters' protective clothing under the cover of the water mist. In the continuous push-type fire-fighting process, the temperature of the firefighters' protective clothing can be prevented from accumulating too high, thereby improving the safety of firefighting.

When the electromagnetic valve 16 is opened, the switching of the electromagnetic reversing valve 7 is controlled to realize the switching of the connection between the suction pump 11 and the gas storage bottle 5, thereby realizing the switching of the inflation and exhaust of the stacking tube 20.

[0057] See also Fig.12 The development board 44 is provided with a transmission control module, which includes a waveform array information receiving module, an infrared thermal imaging receiving module and an air pressure value signal receiving module. The power line of the millimeter wave radar head 32 is connected to the power output post of the battery pack 101, and the signal output serial line of the millimeter wave radar head 32 is connected to the serial line signal receiving pin of the waveform array information receiving module. The power line of the thermal infrared probe 40 is connected to the power output post of the battery pack 101, and the transmission line of the thermal infrared probe 40 is connected to the signal input pin of the infrared thermal imaging receiving module. The waveform array information receiving module is used to receive millimeter waves. The radar head 32 feeds the millimeter wave reflection feed point signal, and introduces each millimeter wave reflection feed point signal into the three-dimensional array coordinates, and converts it into a quadrant point; the infrared thermal image receiving module is used to receive the thermal image of the firefighter's outer protective clothing through the storage frame 1 input by the thermal infrared probe 40 in real time; the air pressure value signal receiving module is used to receive the air pressure value input from the electronic barometer in real time; the waveform array information receiving module is connected to the excess column removal module, and the excess column removal module is used to remove the overlapping quadrant points and the quadrant points in the area of ​​the storage frame 1 in real time, thereby retaining the quadrant points of the left area of ​​the fire channel. The remaining column removal module is connected to the ranging processing module, and the ranging processing module is used to calculate the distance of the remaining quadrant points. During the calculation process, the time from the emission to the reflection feed of the millimeter wave transceiver array element corresponding to each quadrant point is recorded, and the product with the millimeter wave transmission speed is introduced to calculate the round-trip length of the quadrant point. The obtained round-trip length is divided by 2 to obtain the distance U between the millimeter wave transceiver array element and the measured point. Since the distance C between the millimeter wave transceiver array element and the leftmost inner support frame 23 in the contracted state is constant and known, when calculating the extendable distance Y of the quadrant point, Y=UCR is calculated. , where R is the spacing value in centimeters, and the corresponding Y value is marked for each quadrant point in the three-dimensional array coordinates; the infrared thermal image receiving module is connected to the temperature measurement processing module, which is used to denoise the thermal image and analyze the color of the thermal image to obtain the corresponding temperature threshold. The thermal image is denoised by binary image processing to ensure the stability of the thermal image in the subsequent comparison and analysis process with the thermal image spectrum. Since each color change in the thermal image spectrum corresponds to the corresponding temperature threshold, the area corresponding to the thermal image spectrum is determined by comparing the uploaded thermal image with the thermal image spectrum, thereby determining the temperature threshold;

[0058] The distance measurement processing module and the temperature measurement processing module are connected to the analysis processing module through transmission. The analysis processing module is bidirectionally connected to the signal relay processing module. The signal relay processing module is used to perform signal relay processing for the analysis processing module and the industrial computer 45. The signal access pin of the signal relay processing module is connected to the signal access end of the industrial computer 45 through transmission.

[0059] The analysis and processing module is used to set the opening limit according to the shortest distance value obtained by the distance measurement processing module, and is also used to determine whether to start the heat drive mechanism according to the comparison between the highest temperature threshold value obtained by the temperature measurement processing module and the standard temperature threshold value;

[0060] When the industrial computer 45 issues a command to expand the fire channel, the analysis and processing module scans all quadrant points in the three-dimensional array coordinates to obtain the shortest quadrant point extendable distance YD. At this time, the opening limit setting is set based on the shortest quadrant point extendable distance YD. When setting, first calculate the direction and number of revolutions to be executed by the motor 28. Since the modulus of the motor 28 running revolutions and the direction of revolution corresponding to any length position when the winding rope 31 is released or retracted is known, by matching YD with the length of the winding rope 31 when it is released or retracted, and deriving the corresponding motor 28 running revolutions and the modulus of the direction of revolution, when the motor 28 has executed the revolutions and the modulus of the direction, by analyzing the air pressure value for 4 consecutive seconds, if the air pressure value continues to increase, a solenoid valve 16 continues to open the valve command, and when the air pressure value does not change for 4 consecutive seconds, a solenoid valve 16 closes the valve command. This is the program displayed in the analysis and processing module;

[0061] When the industrial computer 45 issues a command to fold the fire-fighting passage, the analysis and processing module sends a return speed and a steering command to the steering CNC input module until the motor 28 stops running. In the early stage of this execution, a suction command is sent to the frequency conversion signal control input module until the real-time input air pressure value is zero. Then a stop suction command is issued, and the return speed and steering command are sent to the steering CNC input module. This is the folding procedure in the analysis and processing module.

[0062] When the frequency conversion signal control module executes the suction command, the analysis and processing module identifies the YD value. When the YD value is limited to 2 meters, the basic operating speed of the motor of the suction pump 11 is 500r / min. For every additional 0.5 meters, the frequency conversion signal control module increases the motor operating speed of the suction pump 11 by 80r / min. The overall speed reaches 1200r / min and does not increase further.

[0063] The analysis and processing module scans the temperature thresholds of each area in the obtained thermal image, and compares the highest temperature threshold with the standard temperature threshold. If it is lower than or equal to the standard temperature threshold, no operation instruction is issued to the steering speed control input module 2 and the relay signal control input module 3. If it is higher than the standard temperature threshold, a reciprocating steering speed operation instruction of the motor 2 38 is issued to the steering speed control input module 2, and an opening instruction of the electromagnetic water valve 102 is issued to the relay signal control input module 3; until it is lower than or equal to the standard temperature threshold, a stop operation instruction of the motor 2 38 is issued to the steering speed control input module 2, and a closing instruction of the electromagnetic water valve 102 is issued to the relay signal control input module 3.

[0064] The analysis and processing module is connected with the steering digital control input module 1, the steering digital control input module 2, the frequency conversion signal control input module, the relay signal control input module 1, the relay signal control input module 2, and the relay signal control input module 3;

[0065] Among them, the signal output pins of the steering digital control input module 1 and the steering digital control input module 2 are respectively connected to the signal input ends of each driver in the driver group 46 through signal lines, the signal output pins of the frequency conversion signal control input module are connected to the control signal input end of the frequency converter 15 through signal lines, and the signal output pins of the relay signal control input module 1, the relay signal control input module 2 and the relay signal control input module 3 are connected to the signal input ends of each control position area of ​​the integrated relay 42 through signal lines.

[0066] The steering digital control input module 1, the frequency conversion signal control input module, the relay signal control input module 1 and the relay signal control input module 2 receive the operation instruction under the limit setting, and automatically execute the stop operation instruction when the limit setting is reached;

[0067] The steering digital control module 2 and the relay signal control module 3 issue control commands after obtaining the operation commands issued by the analysis and processing module;

[0068] The steering digital control module 1 is used to control the operation of the motor 1 28, the steering digital control module 2 is used to control the operation of the motor 2, the frequency conversion signal control module is used to control the operation speed of the suction pump 11, the relay signal control module 1 is used to control the reversing operation of the electromagnetic reversing valve 7, the relay signal control module 2 is used to control the on-off of the electromagnetic valve 16, and the relay signal control module 3 is used to control the on-off of the electromagnetic water valve 102;

[0069] The industrial computer 45 is used to change the open limit setting and the standard temperature threshold in the analysis and processing module through the signal relay processing module, and to issue operation instructions to the analysis and processing module through the signal relay processing module.

[0070] The instructions for opening and closing the fire fighting channel are set in the industrial computer 45, and the signal relay processing module and the analysis processing module respond to the opening and closing of the program.

[0071] When changing, the industrial computer is allowed to set 45 pairs of R, but the minimum R shall not be less than 2 cm; the industrial computer is allowed to set 45 pairs of standard temperature thresholds, but the highest value of the standard temperature threshold shall not be less than 100°C.

[0072] In the specific control mode, the operation is as follows:

[0073] Retractable mechanism, suction and inflation mechanism, folding tube 20 and millimeter wave radar head 32: When the industrial computer 45 issues an instruction to expand the fire fighting channel, the analysis and processing module obtains the length of the executable release rope 31, and the retractable mechanism releases the rope 31 according to the executable release length. At the same time, the control mechanism controls the electromagnetic valve 16 in the suction and inflation mechanism to open the valve, and the electromagnetic reversing valve 7 to switch, connect the gas cylinder 5 with the connecting pipe 14, inflate the folding tube 20, push the inner support frame 23 to move outward, the shear frame 24 is extended, and each surface layer is laid outward, until the retractable mechanism releases the rope 31 and stops when the length of the executable release rope 31 is reached. By analyzing the air pressure value for 4 consecutive seconds, if the air pressure value continues to increase, the electromagnetic valve 16 continues to open the valve instruction, and if the air pressure value does not change for 4 consecutive seconds, the electromagnetic valve 16 closes the valve instruction.

[0074] When the industrial computer 45 issues an instruction to fold up the fire-fighting passage, the control mechanism controls the opening of the solenoid valve 16, and the solenoid reversing valve 7 is reversed to connect the suction pump 11 with the connecting pipe 14. The suction pump 11 in the suction and inflation mechanism is controlled to operate to pump nitrogen in the stacking tube 20 after a delay of 1 second until the real-time input air pressure value is zero. The motor 28 is controlled to perform a return operation to fold up the inner support frame 23 toward the U-shaped inner groove direction of the storage frame 1, fold up the scissors frame 24, and fold up each surface layer until they return to the initial folded state.

[0075] During the whole process, a single person can stand in the aisle area not covered by the fire and simply issue control instructions to quickly achieve the erection and folding operations. The millimeter-wave radar head 32 that can penetrate thick smoke and fire for distance measurement is used for distance detection, and the module in the control mechanism calculates the executable deployment length, and executes the deployment channel according to the executable deployment length. Therefore, in the case of thick smoke and fire obstruction, it can avoid hitting the aisle facilities.

[0076] With the arrangement of the inner and outer fabrics of the inner support frame 23 and the shear frame 24, the fire-fighting passageway not only has the ability of heat-resistance, fire-insulation and heat preservation, but also has the ability of resisting falling objects. Therefore, when deployed, it can effectively provide a fire-avoiding barrier for firefighters, making the fire-fighting process in the aisle safer for firefighters.

[0077] Heat-removing mechanism, thermal infrared probe 40 and control mechanism: When the firefighters pass through the storage frame 1 on their way back, the thermal infrared probe 40 captures the thermal image of the firefighters' body surface, and the control mechanism determines whether to start the heat-removing mechanism based on the corresponding highest temperature value in the thermal image. When the heat-removing mechanism is started, the firefighters only need to stand in the water mist coverage area of ​​the heat-removing mechanism to cool down their protective clothing under the cover of the water mist. In the process of continuous push-type firefighting, it can prevent the firefighters' protective clothing from accumulating too high a temperature, thereby improving the safety of firefighting.

[0078] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
