DETAILED DESCRIPTION
[0022] See also Figure 1-Figure 5 A flame retardancy test device for flame retardant diesel tank production includes a test box 1 and an intermittent rotating mechanism 2 and a combustion mechanism 3 arranged inside the test box 1. The test box 1 includes a box body 101, and a partition 102 is fixedly connected to the lower part of the box body 101:
[0023] The test box 1 serves as a core carrier, and its internal space is sufficient to accommodate the diesel tank to be tested. The stability and safety of the test environment are ensured through careful design. The partition 102 is located at the bottom of the box body 101, which may be used to separate the combustion area and the equipment operation area to ensure the safety of the test process.
[0024] Furthermore, the intermittent rotating mechanism 2 includes a turntable 201, a rotating shaft 202 is fixedly connected to the bottom of the turntable 201, the bottom of the rotating shaft 202 extends to the bottom of the partition 102 and is rotatably connected thereto, a first motor 203 is fixedly connected to the bottom of the rotating shaft 202, a ratchet 204 is fixedly sleeved on the surface of the rotating shaft 202, the ratchet 204 is rotatably set on the top of the support plate 205, the support plate 205 and the first motor 203 are both fixedly set on the bottom of the inner wall of the box body 101, a pawl 206 is clamped on the surface of the ratchet 204, the pawl 206 is rotatably set on the top of the support plate 205, the top of the support plate 205 is fixedly connected to a mounting block 208, and a spring 207 is fixedly connected between the pawl 206 and the mounting block 208.
[0025] The turntable 201 is designed to carry the diesel tank sample to be tested. As the rotating shaft 202 rotates, the angle of the diesel tank facing the combustion mechanism 3 changes. The rotating shaft 202 is driven by the first motor 203 to achieve intermittent or continuous rotation. The ratchet 204 and the pawl 206 cooperate to achieve the function of intermittent rotation. When the ratchet 204 rotates, the pawl 206 periodically clamps the teeth of the ratchet 204 under the action of the spring 207, so that the turntable 201 can only rotate according to the set step angle, so that different parts of the diesel tank can be flame-retardant tested at different preset positions. The device realizes multi-angle automated flame-retardant performance testing of the diesel tank to be tested through a precise mechanical structure, which can more realistically reflect the flame-retardant performance of the diesel tank under different fire conditions, and help to improve product quality and safety.
[0026] Furthermore, a first electric push rod 104 is fixedly connected to one side of the inner wall of the box body 101, and a movable end of the first electric push rod 104 is fixedly connected to an arc-shaped limiting plate 103 that fits the surface of the fuel tank.
[0027] The function of the first electric push rod 104 is to ensure that the fuel tank can be firmly and accurately fixed at the test position during the flame retardant test. The arc-shaped limit plate 103 is designed to fit the surface shape of the fuel tank, and can provide effective support and limitation from one side when the fuel tank is subjected to a rotation test, thereby preventing the fuel tank from being displaced due to centrifugal force or other external forces during the rotation process, and ensuring that the burning flame is always aligned with the preset test point during the test.
[0028] Furthermore, a second electric push rod 106 is fixedly connected to the top of the box body 101, and a movable end of the second electric push rod 106 extends into the inside of the box body 101 and is fixedly connected to a stop plate 105 that fits the top of the fuel tank.
[0029] The main function of the second electric push rod 106 is to clamp and position the top of the fuel tank to ensure that during the flame retardant test, no matter what tilt or rotation state the fuel tank is in, its top can be kept tightly fitted and stably pressed to avoid test failure or safety hazards caused by loose top. This device ensures the rigor and safety of the test process through multiple fixing and positioning measures on the bottom, sides and top of the fuel tank, while also improving the accuracy of the test results.

[0031] The double-opening design of the first door 107 and the second door 108 allows a larger opening range, which is beneficial to the daily maintenance, cleaning and troubleshooting of the equipment. By providing handles on the front sides of the first door 107 and the second door 108, the staff can easily open and close the first door 107 and the second door 108, so that the flame retardant diesel tank to be tested is placed in or taken out of the test device. At the same time, the first door 107 and the second door 108 can also be quickly closed during the test to ensure the airtightness and safety of the test environment.
[0032] Furthermore, a transparent glass window 109 is embedded in the front side of the first door 107 , and a base 110 is fixedly connected to the bottom of the box body 101 .
[0033] The transparent glass window 109 embedded in the front side of the first box door 107 enables the operator to clearly and intuitively observe the test process inside the box body 101, such as the state change of the fuel tank when it is subjected to flame combustion, without opening the first box door 107. This not only ensures the convenience of experimental observation, but also avoids unnecessary heat loss and external factors that interfere with the test environment. The main function of the base 110 is to provide stable support to ensure that the entire test device will not shake or tip over during operation, ensuring the smooth progress of the test process.
[0034] Furthermore, the combustion mechanism 3 includes a gas nozzle 301, a plurality of ignition guns 302 are fixedly connected to one side of the gas nozzle 301, an elastic hose 303 is fixedly connected to the top of the gas nozzle 301, and one end of the elastic hose 303 extends to the outside of the box 101 and is fixedly connected to a gas tank 304.
[0035] The gas nozzle 301 is the core component of the combustion mechanism 3. The gas nozzle 301 is responsible for spraying gas into the diesel tank to be tested to simulate a real combustion environment. A plurality of ignition guns 302 are fixedly connected to one side of the gas nozzle 301. They can accurately ignite the sprayed gas to ensure the effective triggering of the combustion reaction. The top of the gas nozzle 301 is connected to the gas tank 304 outside the box 101 through an elastic hose 303. This design allows the gas pipeline to have a certain degree of flexibility to adapt to slight movements that may occur during the test and facilitate the replacement of the gas tank 304.
[0036] Furthermore, a lifting plate 305 is fixedly connected to one side of the gas nozzle 301, and a threaded rod 306 is threadedly connected to one side of the inner wall of the lifting plate 305. The bottom of the threaded rod 306 is rotatably connected to the top of the partition 102. The top of the threaded rod 306 extends to the top of the box body 101 and is fixedly connected to a second motor 307. The second motor 307 is fixedly set on the top of the box body 101. The inner wall of the lifting plate 305 is slidably connected to a limit rod 308, and the limit rod 308 is fixedly set between the box body 101 and the partition 102.
[0037] The gas nozzle 301 can be adjusted in height through the lifting plate 305, and can be accurately positioned according to the specific position and size of the diesel tank to be tested, ensuring that the flame can directly contact the test target part. The second motor 307 can control the rotation of the threaded rod 306, thereby driving the lifting plate 305 to rise or fall, thereby achieving height adjustment of the combustion mechanism 3. The limit rod 308 is fixed between the box body 101 and the partition 102, providing guidance and limiting functions for the up and down movement of the lifting plate 305, ensuring its stable operation within the specified travel range, and preventing excessive lifting from causing equipment damage or safety accidents.
