Description

Technical Field

[0001] The utility model relates to the technical field of flame retardant performance testers, in particular to a lifebuoy flame retardant performance tester with a function of filtering harmful gases. Background Art

[0002] A lifebuoy is a type of water lifesaving equipment, typically made of cork, foam plastic, or other lightweight materials with a low specific gravity, and covered with canvas, plastic, or the like. In the prior art, flame retardancy testing is required during the production of lifebuoys. A Chinese utility model patent, Publication No. CN213933735U, discloses a mask flame retardancy tester. This utility model involves looping a mask tensioning rope around a first rod and a second rod, then moving the second rod to tighten the tensioning rope, allowing the mask to be deployed. Furthermore, rotating a screw can change the distance between the two support blocks, also allowing the mask to be deployed.

[0003] However, the mask cannot be rotated and adjusted, and the fire source can only test a specific position of the mask, so the test is relatively one-sided. When testing the lifebuoy, only the lower position of the lifebuoy can be tested, and the test result is not accurate enough. At the same time, a large amount of smoke will be generated during the test. The utility model does not have a smoke processing structure, which is easy to affect the surrounding air environment, so it needs to be improved. Utility Model Content

The movable gear 609 is movably installed with the No. 1 transmission gear 608, and the movable groove 611 is opened on both sides of the transmission tube 610. The limiting rod 613 is fixedly connected to the transmission rod 612, and the transmission rod 612 is located in the movable groove 611. The spring 614 is movably installed in the transmission tube 610 and is located above the transmission rod 612. The test assembly 6 also includes a No. 1 stepper motor 615 and a No. 2 stepper motor 616. The No. 1 stepper motor 615 and the No. 2 stepper motor 616 are fixedly connected to the bottom surface of the test box 1. The output shaft of the No. 1 stepper motor 615 is fixedly connected to the No. 2 screw 602. The output shaft of the No. 2 stepper motor 616 is fixedly connected to the transmission rod 612. The No. 1 stepper motor 615 is started, so that the No. 2 screw rod 602 is started, and the movable block 604 moves up or down. The rotating rod 605 moves synchronously with the movement of the movable block 604. The No. 2 stepper motor 616 is started, so that the transmission rod 612 and the transmission tube 610 are rotated, so that the No. 2 transmission gear 609 rotates, and the No. 2 transmission gear 609 rotates the No. 1 transmission gear 608, so that the rotating rod 605 rotates. The rotating rod 605 rotates the lifebuoy, so that the lifebuoy rotates and adjusts its position to fully test the flame retardant performance.

[0024] The connecting sleeve 617 is fixedly connected to the upper position of the test box 1, the fan sleeve 619 is movably connected to the connecting sleeve 617, and the exhaust fan 620 is movably installed in the fan sleeve 619. The test assembly 6 also includes a first filter plate 618, a second filter plate 621 and an air intake filter plate 622. The first filter plate 618 is fixedly connected to the connecting sleeve 617, the second filter plate 621 is fixedly connected to the bottom of the fan sleeve 619, and the air intake filter plate 622 is fixedly connected to the two sides of the bottom of the test box 1. The fan sleeve 619 is sleeved in the connecting sleeve 617 and is engaged with each other. There is a space between the first filter plate 618 and the second filter plate 621 for filling with activated carbon particles. When the exhaust fan 620 is started, the gas in the test box 1 is extracted outward. The gas passes through the first filter plate 618, the activated carbon layer and the second filter plate 621, so as to absorb and filter harmful substances in the gas to avoid affecting the surrounding air quality.

[0025] It should be noted that the present invention is a flame retardant performance tester for a lifebuoy with a harmful gas filtering function. The lifebuoy is placed on the rotating rod 605 and located between the two limiting blocks 606. The No. 1 stepper motor 615 is started, the No. 2 screw 602 rotates, and a screw hole is provided on the movable block 604 at a position corresponding to the No. 2 screw 602. As the No. 2 screw 602 rotates, the movable block 604 rotates, the height of the rotating rod 605 is adjusted, and the No. 1 transmission gear 608 at the side of the rotating rod 605 moves synchronously. The No. 1 transmission gear 608 and the No. 2 transmission gear 609 engage with each other to transmit the signal. The first transmission gear 608 moves upward, the second transmission gear 609 and the transmission tube 610 move upward, the compressed spring 614 gradually recovers upward, and the limiting rod 613 moves downward in the movable groove 611 of the transmission tube 610. When the first transmission gear 608 moves downward, the second transmission gear 609 and the transmission tube 610 move downward, and the spring 614 is further compressed, thereby maintaining the meshing transmission of the first transmission gear 608 and the second transmission gear 609. After adjusting the rotating rod 605 to the appropriate position, the second stepping motor 616 is started to rotate the transmission rod 612. The transmission tube 610 is rotated by limiting the rod 613, so that the transmission tube 610 rotates, and the second transmission gear 609 on the transmission tube 610 rotates. The first transmission gear 608 and the second transmission gear 609 are meshed and transmitted, so that the first transmission gear 608 and the rotating rod 605 rotate. As the rotating rod 605 rotates, the life buoy slowly rotates to adjust the position. Flames are ejected from the burner 4 through the nozzle 5 below to perform a flame retardant test on the life buoy. As the life buoy rotates, it is convenient to perform a flame retardant test on the life buoy more fully, and the test results are more accurate. Between the first filter plate 618 and the second filter plate 621 Filled with an activated carbon layer, the exhaust fan 620 is started and rotates in the fan sleeve 619 to exhaust the air in the test box 1 to the outside. After the test box 1 forms a negative pressure, the test box 1 absorbs external gas through the air intake filter plate 622, so that sufficient oxygen is maintained in the test box 1, so that the flame can continue to burn. During the combustion of the flame, a large amount of smoke is generated. This smoke enters the connecting sleeve 617 at the upper position. The activated carbon filled between the first filter plate 618 and the second filter plate 621 filters and absorbs the smoke, making it easy to filter out harmful gases and prevent the exhausted air from affecting the surrounding air quality.

[0026] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
