Description

Technical Field

[0001] This utility model belongs to the technical field of life jacket testing equipment, and more specifically, it relates to a life jacket flammability testing device. Background Technology

[0002] Lifesuits (such as immersion suits and exposure suits) are essential personal protective equipment for personnel in high-risk environments such as ships and offshore platforms. Their core function is to provide buoyancy and thermal protection for the wearer in the event of falling into the water or in extreme environments. According to the International Maritime Organization (IMO) Convention for the Safety of Life at Sea (SOLAS) and relevant Chinese standards (such as GB / T 18916-2020 "Lifesuits"), lifesuits must have strict flame-retardant properties—when exposed to open flames or high temperatures, the material should not burn, melt, or spread flames rapidly to avoid secondary injuries to the wearer due to clothing combustion in emergency situations.

[0003] Current flammability testing of life jackets primarily relies on manual operation: testers hold the life jacket or secure it with simple clamps, manually move it above a flame source (such as a burning brazier), hold it there for a specified time, and then move it to a safe area to observe the results. This method has the following drawbacks: 1. Poor test consistency: Uneven manual movement speed (such as fluctuating speed) and difficulty in accurately controlling flame contact time (such as deviation in dwell time) lead to low repeatability of test results; 2. High operational risk: Test personnel need to be in close contact with open flames (the temperature of the fire pit can reach hundreds of degrees Celsius), which can easily lead to burns or fire accidents; 3. Low efficiency: Each test requires repeated manual adjustment of the position, which is time-consuming and labor-intensive, and cannot meet the needs of batch testing; 4. Low level of automation: It lacks a standardized automatic movement and flame exposure control mechanism, making it difficult to link with detection instruments (such as temperature sensors and timers) to record data.

[0004] Therefore, there is an urgent need for an automated, safe and reliable testing device for the flammability of life jackets, which can achieve uniform lateral movement of the life jacket and precise contact with flames through a mechanical structure, thereby improving testing accuracy and operational safety. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a device for testing the flammability of life jackets, thereby resolving the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a life jacket flammability testing device, comprising two parallel supporting vertical rods, a horizontal rod fixedly connected between the two supporting vertical rods, a fixedly connected supporting slide rail on the side of the horizontal rod, a transverse movement mechanism on the horizontal rod, the transverse movement mechanism comprising a transverse movement bracket, a slider slidably connected to the supporting slide rail on the surface of the transverse movement bracket, a drive motor on the surface of the transverse movement bracket, a roller on the output shaft of the drive motor, a slide rail adapted to the roller on the surface of the horizontal rod, a life jacket hook fixedly connected to the bottom of the transverse movement bracket, and a fire basin placement platform between the two supporting vertical rods.

[0007] Preferably, the roller surface is covered with a wear-resistant rubber layer.

[0008] Preferably, the bottom of the two supporting vertical rods is provided with supporting feet, and the bottom of the supporting feet is provided with anti-slip pads.

[0009] Preferably, both ends of the crossbar are provided with fixedly connected limiting baffles.

[0010] Preferably, the controller is a PLC controller or a microcontroller controller.

[0011] This utility model provides a device for testing the flammability of life jackets, which has the following beneficial effects: 1. High degree of automation: The motor-driven rollers enable the life jacket to move at a constant speed, avoiding speed fluctuations caused by manual movement and ensuring precise control of the flame contact time and position; 2. High safety: Operators do not need to come into close contact with open flames, reducing the risk of burns and meeting laboratory safety standards; 3. Good test consistency: The controller precisely adjusts the roller speed and dwell time to ensure that the test conditions are the same each time, thus improving the repeatability of the results.

Detailed Implementation

[0017] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0018] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] Please see Figures 1 to 4 This utility model provides a technical solution: a life jacket flammability testing device includes two parallel supporting vertical rods 1, with a horizontal rod 2 fixedly connected between the two vertical rods, forming the main support structure of the device. A horizontal movement mechanism 4 is installed on the horizontal rod 2, including a horizontal movement bracket 41, a slider 42, a drive motor 43, a roller 44, and a life jacket hook 6. The horizontal movement bracket 41 has a slider 42 fixed to its surface, which is slidably connected to a supporting slide rail 3 (located on the side of the horizontal rod 2), ensuring smooth movement of the horizontal movement bracket 41 along the direction of the horizontal rod 2. The drive motor 43 is fixed to the surface of the horizontal movement bracket 41, and its output shaft is connected to the roller 44. The surface of the horizontal rod 2 is provided with a slide rail 45 adapted to the roller 44, and the roller 44 drives the horizontal movement bracket 41 to move horizontally through the slide rail 45. A life jacket hook 6 is fixedly connected to the bottom of the horizontal movement bracket 41 for suspending the life jacket to be tested.

[0021] The fire basin placement platform 7 is located between the two supporting vertical rods 1 and directly below the horizontal rod 2, and is used to place the test fire basin (containing fuel and producing flames).

[0022] The transverse support 41 is also equipped with a protective shell 8 (containing a controller 9 that is connected to the drive motor 43 for control), and the surface of the roller 44 is covered with a wear-resistant rubber layer 10 to increase friction; the bottom of the support vertical rod 1 is equipped with a support foot 11 (with an anti-slip pad 5 at the bottom), and the two ends of the horizontal rod 2 are equipped with limit baffles 12 to prevent the transverse support 41 from falling out; the controller 9 is a PLC controller 9 or a single-chip microcomputer controller 9.

[0023] Working principle: During the test, the life jacket to be tested is suspended on the life jacket hook 6. The drive motor 43 is started, and the roller 44 rolls along the slide rail 45 of the crossbar 2, which drives the horizontal moving bracket 41 and the life jacket to move at a constant speed along the crossbar 2. When the life jacket moves directly above the fire pit, the flame exposes it to heat (the duration can be controlled by an external timer or a preset program of the controller 9). After the movement is completed, the life jacket is removed from the flame area, and it is observed whether there are any abnormal phenomena such as burning or melting, and the test is completed.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
