Description

Technical Field

[0001] This invention relates to the field of protective clothing testing technology, specifically to a protective clothing combustion testing device based on intelligent sensors. Background Technology

[0002] Traditional protective clothing combustion tests rely heavily on manual observation and static parameter control, which suffers from problems such as delayed data acquisition, limited testing scenarios, and inability to accurately capture local combustion dynamics. With the development of intelligent sensing technology, sensors for temperature, flame intensity, and fabric deformation are integrated into the testing device, which can monitor the microscopic changes of various parts of the protective clothing in real time during the combustion process. This solves the pain points of traditional testing, such as strong subjectivity and incomplete data, and meets the need for more accurate and dynamic evaluation of the protective performance of protective clothing.

[0003] Patent CN218766809U discloses a protective clothing combustion testing device, including a support frame. An mounting bracket is fixedly installed on the upper surface of the support frame, and an observation plate is mounted on the front of the mounting bracket. A second motor is fixedly installed on the lower surface of the support frame. A disc is rotatably mounted on the support frame and fixedly connected to the output shaft of the second motor. A dummy is detachably mounted on the upper surface of the disc. The dummy wears a protective suit, foot covers, and a protective cap. By setting up the second motor, the disc, the dummy, the protective suit, the protective cap, the foot covers, and a flame gun, the dummy can put on the protective suit, cap, and foot covers. The flame gun facilitates better testing. Simultaneously, the second motor drives the disc to rotate, which in turn drives the dummy to rotate synchronously. The rotation of the dummy causes the protective suit, cap, and foot covers to move synchronously, enabling a more comprehensive testing of the protective suit.

[0004] However, when the above-mentioned device is in use, it is difficult to synchronously drive the flame gun to rotate up and down during the rotation of the protective suit. This results in blind spots in the flame gun's test of the protective suit, affecting the results of subsequent combustion tests on the protective suit. Therefore, a protective suit combustion test device based on intelligent sensors is proposed to solve the above-mentioned problems. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a protective clothing combustion testing device based on intelligent sensors, which addresses the shortcomings of the prior art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a protective clothing combustion testing device based on intelligent sensors, including a control console, a testing cabinet on the control console, a simulation mechanism for simulating real motion on the inner wall of the testing cabinet, an exhaust mechanism for ventilation on the inner wall of the testing cabinet, a rotating disk rotatably connected to the inner wall of the testing cabinet, a human model mounted on the rotating disk, a fire-fighting protective suit mounted on the human model, a toothed ring one fixedly connected to the circumference of the rotating disk, and a toothed ring two rotatably connected to the inner wall of the testing cabinet, the inner wall of the toothed ring two... A reciprocating lead screw is rotatably connected to the device. A fixed column is fixedly connected to the inner wall of the second gear ring. A moving block is movably connected to the circumferential surface of the reciprocating lead screw. A flame gun is fixedly connected to the inner wall of the moving block. A roller is fixedly connected to the circumferential surface of the reciprocating lead screw. A motor is installed on the inner wall of the test cabinet. A temperature sensor is installed on the human body model. This ensures that the heat flow is uniform during the rotation of the fire protective suit, and that the test is conducted without blind spots, simulating the actual wearing condition. This improves the quality of the flame test of the fire protective suit and enhances the accuracy of the test combustion of the fire protective suit.

[0007] Preferably, the rotating disk is fixedly connected to the output end of the motor, the first gear ring meshes with the second gear ring, and the first gear ring is used to drive the second gear ring to rotate. The moving block is slidably connected to the circumferential surface of the fixed column. The up-and-down rotation of the flame gun can spray flames to conduct flame tests on the surface of the fire protective clothing. At the same time, the temperature sensor on the surface of the human model can test the internal temperature of the fire protective clothing. By rotating and moving the flame gun, the device can improve the all-round combustion test detection of the fire protective clothing and improve the combustion test effect of the device.

[0008] Preferably, the movable block contacts the fixed column, and the fixed column is used to guide and limit the movement of the movable block. The roller contacts the test cabinet, and the roller is used to drive the reciprocating screw to rotate, so that the reciprocating screw rotates synchronously around itself as the rotation center. The rotation of the reciprocating screw around itself as the rotation center will drive the movable block to rotate. However, at this time, the movable block is guided and limited by the fixed column. At this time, during the rotation of the reciprocating screw, the movable block can only move up and down back and forth through the reciprocating groove on the surface of the reciprocating screw.

[0009] Preferably, the simulation mechanism includes an electric telescopic rod, which is fixedly connected to the inner wall of the test cabinet. A connecting plate is fixedly connected to the telescopic end of the electric telescopic rod, and a limit cover is fixedly connected to the bottom of the connecting plate. A locking block is fixedly connected to the inner wall of the limit cover. This mechanism can reproduce the dynamic movement of the head of the fire protective suit, expose the blind spot of the neck protection inside, accurately evaluate the performance of the head protection area, improve the combustion test results of the protective suit, and enhance the combustion test quality of the device.

[0010] Preferably, the simulation mechanism further includes an elastic telescopic rod, which is fixedly connected to the inner wall of the test cabinet. An arc block is fixedly connected to the telescopic end of the elastic telescopic rod, and a connecting rod is fixedly connected to the inner wall of the arc block. A sealing plate is fixedly connected to the inner wall of the connecting rod. A water storage column is fixedly connected to the inner wall of the test cabinet, and an atomizing nozzle is fixedly connected to the bottom of the water storage column. The atomizing nozzle can spray the water inside the water storage column in an atomized form onto the surface of the fire protective clothing, which can simulate the liquid interference scenario in a real fire, accurately evaluate the liquid resistance and flame retardant synergistic performance of the protective clothing fabric, and improve the accuracy of the combustion test.

[0011] Preferably, the connecting plate is located directly above the fire protective suit, the locking block is in contact with the fire protective suit, and the locking block is used to drive the head of the fire protective suit to rotate at an angle, the arc block is located on the movement trajectory of the roller, and the roller is used to drive the arc block to move, the sealing plate is in contact with the atomizing nozzle, and the sealing plate is used to seal the atomizing nozzle. During the rotation of the roller around the rotating disk as the rotation center, the roller will contact the arc block and squeeze and push the arc block. The movement of the arc block will drive the connecting rod to move, and the movement of the connecting rod will drive the sealing plate to move.

[0012] Preferably, the exhaust mechanism includes a fixed frame, which is fixedly connected to the top of the limiting cover. A connecting block is fixedly connected to the top of the fixed frame, and a pull rod is rotatably connected to the circumferential surface of the connecting block. A sliding rod is slidably connected to the inner wall of the test cabinet, and a sealing plate is fixedly connected to the top of the sliding rod. The pull rod is rotatably connected to the circumferential surface of the sliding rod, so that the sealing plate can open the ventilation opening of the test cabinet. This can simulate the dynamic changes of oxygen in a real fire scene, evaluate the smoke diffusion and heat insulation effect after the protective clothing burns, ensure the stability and repeatability of the test environment, and restore the wrinkle shape of real clothing, avoiding test distortion.

[0013] Preferably, the exhaust mechanism further includes a connecting frame, which is fixedly connected to the bottom of the movable block. An elastic telescopic rod II is fixedly connected to the inner wall of the connecting frame. A connecting groove plate is fixedly connected to the telescopic end of the elastic telescopic rod II. A roller is rotatably connected to the circumferential surface of the connecting groove plate. This avoids the situation where the protective ability of the folded parts is overestimated because the clothing is always kept flat, resulting in a situation where the test is qualified but there is still a risk when wearing it. This accurately detects the shortcomings of flame retardancy and heat insulation in the folded parts.

[0014] Preferably, the sealing plate is in contact with the test cabinet and is used to improve the air circulation speed. The roller is in contact with the fire protective clothing. The movement of the moving block will drive the connecting frame to move synchronously. The movement of the connecting frame will drive the elastic telescopic rod two to move. The movement of the elastic telescopic rod two will drive the connecting groove plate to move.

[0015] The present invention, by adopting the above technical solution, can bring the following beneficial effects: 1. This intelligent sensor-based protective clothing combustion testing device, through the coordinated movement of a control console, test cabinet, human body model, fire protective clothing, rotating disk, gear ring one, gear ring two, reciprocating screw, fixed column, moving block, flame gun, and rollers, ensures uniform heat flow during subsequent flame testing of the fire protective clothing during rotation. This results in comprehensive testing without blind spots, simulating real-world wearing conditions and improving the quality and accuracy of flame testing. The up-and-down rotation of the flame gun sprays flames onto the surface of the fire protective clothing for flame testing, while temperature sensors on the surface of the human body model measure the internal temperature of the clothing. The rotation of the flame gun enhances the device's ability to perform all-around combustion testing of the fire protective clothing, thus improving the overall combustion testing effect.

[0016] 2.

It can accurately evaluate the performance of the head protection area, improve the combustion test results of the protective clothing, and enhance the quality of the combustion test. The atomizing nozzle can spray water from the water storage column into atomized form onto the surface of the fire protective clothing, simulating the liquid interference scenario in a real fire, accurately evaluating the liquid resistance and flame retardant synergistic performance of the protective clothing fabric, and improving the accuracy of the combustion test.

[0017] 3. This protective clothing combustion testing device based on intelligent sensors, through the coordinated movement of the fixed frame, connecting block, pull rod, sliding rod, sealing plate, connecting frame, elastic telescopic rod II, connecting groove plate, and roller, enables the sealing plate to open the ventilation of the test cabinet.

It also avoids the situation where the protective ability of the wrinkled areas is overestimated because the clothing is always kept flat, resulting in a situation where the test is qualified but there is still a risk when wearing it. It accurately detects the flame retardancy and heat insulation deficiencies of the wrinkled areas. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-10One embodiment of the present invention is: a protective clothing combustion testing device based on intelligent sensors, including a control console 1, a test cabinet 2 on the control console 1, a simulation mechanism 5 for simulating real motion on the inner wall of the test cabinet 2, an exhaust mechanism 6 for ventilation on the inner wall of the test cabinet 2, a rotating disk 7 rotatably connected to the inner wall of the test cabinet 2, a human body model 3 mounted on the rotating disk 7, a fire protective suit 4 mounted on the human body model 3, a toothed ring 8 fixedly connected to the circumferential surface of the rotating disk 7, a toothed ring 9 rotatably connected to the inner wall of the test cabinet 2, a reciprocating screw 10 rotatably connected to the inner wall of the toothed ring 9, a fixed column 11 fixedly connected to the inner wall of the toothed ring 9, a moving block 12 movably connected to the circumferential surface of the reciprocating screw 10, a flame gun 13 fixedly connected to the inner wall of the moving block 12, a roller 14 fixedly connected to the circumferential surface of the reciprocating screw 10, a motor on the inner wall of the test cabinet 2, and a temperature sensor on the human body model 3; Before using the device, the tester first needs to put the fire protective suit 4 on the surface of the mannequin 3. After the preparation is completed, the motor will start and the output of the motor will drive the rotating disk 7 to rotate. During the rotation of the rotating disk 7, the rotating disk 7 will drive the mannequin 3 to rotate synchronously. The mannequin 3 will drive the temperature sensor installed on it to rotate synchronously. At the same time, the rotation of the mannequin 3 will drive the fire protective suit 4 to rotate. During the rotation of the fire protective suit 4, the heat flow of the subsequent flame test can be uniform, the test can be detected without dead angles, and the real wearing state can be simulated. This improves the flame test quality of the fire protective suit 4 by the device and improves the test combustion accuracy of the fire protective suit 4. The rotating disk 7 is fixedly connected to the output end of the motor. The first gear ring 8 meshes with the second gear ring 9, and the first gear ring 8 is used to drive the second gear ring 9 to rotate. The moving block 12 is slidably connected to the circumferential surface of the fixed column 11. The moving block 12 contacts the fixed column 11, and the fixed column 11 is used to guide and limit the movement of the moving block 12. The roller 14 contacts the test cabinet 2, and the roller 14 is used to drive the reciprocating screw 10 to rotate. As the rotating disk 7 rotates, it drives the gear ring 8 to rotate, which in turn drives the gear ring 9 to rotate. The rotation of the gear ring 9 drives the reciprocating screw 10 to rotate, and simultaneously, the rotation of the gear ring 9 also drives the fixed column 11 to rotate. During its rotation, the reciprocating screw 10 drives the moving block 12 to rotate, and simultaneously, the rotation of the reciprocating screw 10 drives the roller 14 to move. The roller 14 rotates due to friction generated by contact with the test cabinet 2. The rotation of the roller 14 drives the reciprocating screw 10 to rotate synchronously around itself as its center of rotation, while the rotating disk 7 is the center of rotation. The rotation around itself as the center of rotation will drive the moving block 12 to rotate. However, at this time, the moving block 12 is guided by the movement limit of the fixed column 11. During the rotation of the reciprocating screw 10, the moving block 12 can only move up and down through the reciprocating groove on the surface of the reciprocating screw 10. The up and down movement of the moving block 12 will drive the flame gun 13 to move up and down. While moving, the flame gun 13 will be activated. The up and down rotation of the flame gun 13 can spray flames to test the surface of the fire protective clothing 4. At the same time, the temperature sensor on the surface of the human model 3 can test the internal temperature of the fire protective clothing 4. Through the rotation and movement of the flame gun 13, the device can improve the all-round combustion test detection of the fire protective clothing 4 and improve the combustion test effect of the device.

[0022] Overall working principle: It can ensure uniform heat flow in subsequent flame tests, eliminate blind spots in testing, simulate real wearing conditions, improve the quality of flame testing of the fire protective suit 4, and enhance the accuracy of the test combustion of the fire protective suit 4. While the flame gun 13 is moving, it will be activated. The up-and-down rotation of the flame gun 13 can spray flames to test the surface of the fire protective suit 4. At the same time, the temperature sensor on the surface of the human body model 3 can test the internal temperature of the fire protective suit 4. Through the rotation and movement of the flame gun 13, the device can improve the all-round combustion test detection of the fire protective suit 4, thus improving the combustion test effect of the device.

[0023] Please see Figures 1-10 Based on the above embodiments, in another embodiment of the present invention, the simulation mechanism 5 includes an electric telescopic rod 501, which is fixedly connected to the inner wall of the test cabinet 2. The telescopic end of the electric telescopic rod 501 is fixedly connected to a connecting plate 502, and the bottom of the connecting plate 502 is fixedly connected to a limit cover 503. The inner wall of the limit cover 503 is fixedly connected to a locking block 504. When the device is activated, the electric telescopic rod 501 will start, and the telescopic end of the electric telescopic rod 501 will drive the connecting plate 502 to move downward. The movement of the connecting plate 502 will drive the limiting cover 503 to move downward. The movement of the limiting cover 503 will drive the locking block 504 to move. After the locking block 504 moves downward a certain distance, the locking block 504 can contact the fire protective suit 4. At this time, the human model 3 will rotate, and the human model 3 will drive the fire protective suit 4 to rotate. During the rotation of the fire protective suit 4, the head area of ​​the fire protective suit 4 will be contacted by the locking block 504, which will cause the head area of ​​the fire protective suit 4 to simulate the operation of the wearer shaking his head left and right to observe when using it. It can restore the head dynamics of the fire protective suit 4, expose the neck protection blind spot inside, accurately evaluate the performance of the head protection area, improve the combustion test results of the protective suit, and improve the combustion test quality of the device.

The sealing plate 509 is in contact with the atomizing nozzle 510 and is used to seal the atomizing nozzle 510. When the device is being tested, as the roller 14 rotates around the rotating disk 7, the roller 14 will contact the arc block 507 and squeeze and push the arc block 507. The movement of the arc block 507 will drive the connecting rod 508 to move. The movement of the connecting rod 508 will drive the sealing disk 509 to move. During the movement of the sealing disk 509, the sealing disk 509 can no longer seal the atomizing nozzle 510. At this time, the atomizing nozzle 510 can spray the water inside the water storage column 505 in atomized form onto the surface of the fire protective clothing 4. This can simulate the liquid interference scenario in a real fire, accurately evaluate the liquid resistance and flame retardant synergistic performance of the protective clothing fabric, and improve the accuracy of the combustion test.

A pull rod 603 is rotatably connected to the circumferential surface of the connecting block 602. A slide rod 604 is slidably connected to the inner wall of the test cabinet 2. A sealing plate 605 is fixedly connected to the top of the slide rod 604. The pull rod 603 is rotatably connected to the circumferential surface of the slide rod 604. When the device is activated, the movement of the limit cover 503 will cause the fixed frame 601 to move, the movement of the fixed frame 601 will cause the connecting block 602 to move, the movement of the connecting block 602 will cause the pull rod 603 to move, and the pull rod 603 will change its angle synchronously during the movement. During the angle adjustment, the pull rod 603 will simultaneously cause the slide rod 604 to move laterally, and the movement of the slide rod 604 will cause the sealing plate 605 to move. After the sealing plate 605 moves, it can open the ventilation of the test cabinet 2, which can simulate the dynamic changes of oxygen in a real fire scene, evaluate the smoke diffusion and heat insulation effect after the protective clothing is burned, and ensure the stability and repeatability of the test environment. The exhaust mechanism 6 also includes a connecting frame 606, which is fixedly connected to the bottom of the movable block 12.
