Description

TECHNICAL FIELD

[0001] The utility model relates to fire extinguishing test technical field, concretely is a foam extinguishing agent flame -retardant test device of water mist additive. BACKGROUND

[0002] The existing foam extinguishing agent has certain limitation when coping with class A fire. Class A fire involves various solid combustible materials such as wood, paper, textiles, rubber, plastic, etc. Its combustion process is complex, the fire spreads rapidly, and often accompanied by deep smoldering phenomenon. The traditional foam extinguishing agent is difficult to effectively penetrate into the solid fuel, inhibit the combustion reaction, resulting in low extinguishing efficiency and high risk of rekindling. This is particularly evident in some scenarios such as warehouse fire, forest fire, building fire, etc., which has brought severe challenges to fire safety. The global development trend of fire fighting technology is moving towards multifunctional integration. Developing foam extinguishing agent that can effectively extinguish class B fire and significantly enhance the extinguishing ability of class A fire has become one of the current research hotspots. By adding specific functional additives, new extinguishing properties are given to the foam extinguishing agent, making it able to adapt to the needs of different types of fire fighting, which is a key way to improve the comprehensive performance of the extinguishing agent.

[0003] Through in-depth research and development of water mist additives for foam extinguishing agent for class A fire, the deficiencies of existing foam extinguishing agent in class A fire fighting are solved.

However, this test can only obtain a set of test data, which cannot be compared and is not conducive to the derivation of test results. Therefore, a foam extinguishing agent flame retardant test device containing water mist additives is proposed to facilitate multiple data testing. UTILITY MODEL CONTENT

Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without making creative labor belong to the scope of protection of the utility model.

[0023] Please refer to Figs. 1-4In this embodiment of the invention, a flame-retardant testing device for a foam fire extinguishing agent containing water mist additive includes a test chamber 1. Multiple combustion pools 2 are sequentially arranged on the rear side of the test chamber 1, with the size of the combustion pools 2 increasing sequentially. Different numbers of combustible materials can be placed in the combustion pools 2 of different sizes, thereby creating flame combustion effects of different sizes. Guide grooves 3 are fixedly connected between the top and bottom surfaces of the test chamber 1 and the corresponding combustion pools 2. Partitions 4 are slidably connected to the two corresponding guide grooves 3. The partitions 4 slide through the rear side of the test chamber 1 and are fixedly connected to a back plate 5. The top surface of the test chamber 1 is fixedly mounted on the back plate 5. The test chamber 1 is equipped with an electric telescopic rod 6, the telescopic end of which is fixedly connected to the back plate 5. Each partition 4 has a relief groove 7 on its front side. A guide sleeve 8 is slidably fitted on the front surface of the partition 4 corresponding to the relief groove 7. A spray pipe 9 is connected to the front side of the guide sleeve 8. A nozzle 10 is fixedly connected to each combustion pool 2 of the spray pipe 9. The partition 4 and the test chamber 1 are both equipped with scale lines corresponding to the guide sleeve 8. The side wall of the guide sleeve 8 is threaded with a locking bolt 11. The locking bolt 11 is inserted into the guide sleeve 8 and abuts against the outer wall of the partition 4. The side wall of the guide sleeve 8 is provided with a threaded hole for the threaded connection of the locking bolt 11.

[0024] Multiple combustion pools 2 are set up to form fires of different sizes. Foam extinguishing agent containing water mist additives is sprayed through spray pipes 9 and nozzles 10 to conduct flame retardant effect tests on foam extinguishing agent containing water mist additives, thereby generating multiple sets of test data to facilitate the judgment of the fire extinguishing and flame retardant effect on fire sources of different sizes.

[0025] The spray pipe 9 is installed on the partition plate 4 via the guide sleeve 8. The guide sleeve 8 can slide along the partition plate 4 to adjust the height of the spray pipe 9. At the same time, the partition plate 4 can slide along the guide groove 3 to adjust the distance between the spray pipe 9 and the combustion pool 2. This facilitates flame retardant tests at different distances and heights, generating more flame retardant effect data and determining the usage conditions at different distances.

[0026] The front of the test chamber 1 is provided with a door 12 that is compatible with it. One side of the door 12 is hinged to the test chamber 1 by a hinge, and the other side of the door 12 is provided with a door lock between it and the test chamber 1. The door lock adopts an existing lock body.

[0027] The bottom of the chamber door 12 is provided with an observation window 13, and the top of the test chamber 1 is provided with a vent 14 corresponding to each combustion pool 2. The combustion status of the burning material in the combustion pool 2 inside the test chamber 1 can be observed through the observation window 13. The vent 14 can also be used to allow air to pass through the test chamber 1.

[0028] The door 12 forms an isolation at the front of the test chamber 1, which serves as a safety protection measure.

[0029] One end of the spray pipe 9 is fixedly connected to a connecting hose 15, which extends out of the test chamber 1 and is fixedly connected to a pipe fitting 16.

[0030] The connecting hose 15 is connected to an external foam extinguishing agent supply pipeline containing water mist additives via the pipe fitting 16.

[0031] The front surface of the guide sleeve 8 is fixedly connected with a collar 17. The collar 17 is rotatably sleeved on the outside of the spray pipe 9. A tightening bolt 18 is threadedly connected to the collar 17. The tightening bolt 18 is inserted into the collar 17 and abuts against the spray pipe 9. The collar 17 has a threaded hole for threaded connection of the tightening bolt 18.

[0032] The spray pipe 9 rotates within the collar 17 and is secured by the clamping bolt 18, thereby allowing the orientation of the nozzle 10 to be adjusted so that the nozzle 10 corresponds to the combustion pool 2 after the position of the spray pipe 9 is adjusted.

[0033] A switch 19 is fixedly installed on the side wall of the test chamber 1. The switch 19 is connected to a power source, and the electric telescopic rod 6 is electrically connected to the switch 19 through a wire.

[0034] The working principle of this utility model is as follows:

[0035] In use, the connecting hose 15 is connected to the external foam extinguishing agent supply pipeline containing water mist additives via the pipe connector 16. At this time, the locking bolt 11 is loosened, allowing the guide sleeve 8 to slide, thereby adjusting the height of the spray pipe 9. The locking bolt 11 is then tightened, and the electric telescopic rod 6 is activated, causing the back plate 5 to move, thereby controlling the depth of the partition 4 inserted into the test chamber 1, and thus controlling the distance between the spray pipe 9 and the combustion pool 2. At this time, the abutment bolt 18 is loosened, and the spray pipe 9 is rotated within the collar 17, thereby controlling the nozzle 10 to correspond with the combustion pool 2. At this time, the corresponding amount of combustible material is placed in the combustion pool 2 and ignited. The chamber door 12 is then closed, and the extinguishing agent is delivered through the foam extinguishing agent supply pipeline containing water mist additives. The connecting hose 15 delivers the foam extinguishing agent containing water mist additives to the spray pipe 9, and it is sprayed out by the nozzle 10 into the combustion pool 2 for fire extinguishing. The flame retardant effect of the foam extinguishing agent containing water mist additives is judged by the fire extinguishing situation.

[0036] During the experiment, the height and distance of the spray pipe 9 can be adjusted to create flame-retardant and fire-extinguishing effects at different heights and distances, making the experimental data collection more comprehensive.
