Description

Technical Field

[0001] This utility model relates to the field of fire extinguishing agent effectiveness testing technology, specifically a fire extinguishing agent effectiveness testing device. Background Technology

[0002] In the field of fire extinguishing agent effectiveness testing, in order to ensure the accuracy and reliability of the test results, it is necessary to transport and spray fire extinguishing agents in different physical states (such as liquid, dry powder, etc.) to simulate actual fire extinguishing scenarios.

[0003] For liquid extinguishing agents, solid impurities may be mixed in during production, storage, or transportation. For dry powder extinguishing agents, which are composed of solid particles, they are prone to clumping due to moisture or pressure during storage and transportation, forming large particle clusters. These larger particles and solid impurities are very likely to get stuck in narrow parts of the pipeline, nozzle inlets, or valves when passing through the delivery pipe, causing blockage. Once a blockage occurs, it will not only prevent the dry powder extinguishing agent from being sprayed smoothly and affect the testing process, but also significantly increase the probability of blockage in the delivery pipe and reduce the smoothness of the extinguishing agent delivery.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0017] Please see Figure 1-5 As shown, this utility model is a fire extinguishing agent effectiveness testing device, comprising: Detecting the main body 11; The detection body 11 includes a fire source simulation component, a parameter monitoring component, and a control component: The fire source simulation component is used to simulate fires of different types and scales, including a fuel container, an ignition device, and a fuel supply device. The fuel container can be selected in different shapes and sizes, such as round or square, to simulate different fire scenarios. The ignition device uses electronic ignition and is installed above or on the side of the fuel container, enabling rapid and reliable ignition of the fuel. The fuel supply device is connected to the fuel container to provide a continuous supply of fuel, and the fuel supply can be adjusted according to detection needs to control the size of the fire.

[0018] The parameter monitoring component is used to monitor various parameters during the fire extinguishing process in real time. It includes temperature sensors, smoke concentration sensors, oxygen concentration sensors, pressure sensors, and an image acquisition device. Temperature sensors, employing thermocouples or infrared temperature sensors, are evenly distributed throughout the detection chamber to accurately measure temperature changes. Smoke concentration sensors, using optical or ionization sensors, detect the concentration of smoke within the chamber. Oxygen concentration sensors monitor the oxygen content to determine if the fire has been extinguished. Pressure sensors are installed on the delivery pipes to monitor the injection pressure of the extinguishing agent. The image acquisition device uses a high-definition camera, installed inside or outside the detection chamber, to capture and record the fire extinguishing process in real time through an observation window for subsequent analysis.

[0019] The control components include a controller, a touchscreen, and a data storage device. The controller, a PLC, is electrically connected to the spray assembly, fire source simulation assembly, and parameter monitoring assembly. It receives signals from each sensor and controls the operation of the spray assembly and fire source simulation assembly according to a preset program. The touchscreen, connected to the controller, enables human-machine interaction. Operators can use the touchscreen to set detection parameters, start and stop the detection process, and view detection data and images in real time. The data storage device, also connected to the controller, stores all data and images collected during the detection process for later retrieval and analysis.

[0020] The screening component includes a storage tank 21, an inclined frame 22, a feed trough 23, a support frame 25, and a filter screen 26. The storage tank 21 is fixed on both sides of the outer surface of the detection body 11. The feed trough 23 is opened on one side of the storage tank 21. The inclined frame 22 is embedded in the lower part of the inner surface of the feed trough 23. The support frame 25 is fixed on one side of the top of the inclined frame 22. The filter screen 26 is detachably connected to the inner wall of the support frame 25. By setting a support frame 25 with a filter screen 26 on the top of the inclined frame 22, the liquid or dry powder extinguishing agent poured into the feed inlet can be effectively screened. The inclined design of the inclined frame 22 allows qualified extinguishing agent to pass smoothly through the filter screen 26 into the storage tank 21, while larger impurities and unqualified particles are intercepted on the surface of the filter screen 26. The inclined frame 22 can be disassembled later to clean up the unqualified particles, reducing impurities entering the delivery pipe 36 from the source, significantly reducing the probability of blockage in the delivery pipe 36, and ensuring the smooth delivery of extinguishing agent.

[0021] A positioning rod 24 is fixedly connected to one side of the outer surface of the storage tank 21. Support blocks 27 are provided at both ends of the outer surface of the inclined frame 22. A positioning hole 28 is opened inside the support block 27, and the positioning rod 24 is inserted and connected inside the positioning hole 28. By aligning the positioning rod 24 with the positioning hole 28 and inserting it, the tilting frame 22 can be installed inside the feed trough 23, thus avoiding tilting displacement.

[0022] Guide grooves 32 are provided at the lower part of both ends of the inner surface of the feed trough 23. Guide blocks 34 are slidably connected inside the guide grooves 32. A support seat 33 is fixed between the two guide blocks 34. The support seat 33 is supported on the bottom of the inclined frame 22. An extension plate 31 is fixed at the bottom of the support seat 33. The cooperation between the guide block 34 and the guide groove 32 ensures the precise movement trajectory of the support base 33 until it adheres to the bottom of the inclined frame 22 to form a stable support, preventing the inclined frame 22 from shifting due to gravity when carrying the extinguishing agent. During this process, the extension plate 31 on the outside of the support base 33 moves synchronously with the support base 33, shielding the connection gap between the feed chute 23 and the storage tank 21 to prevent leakage of extinguishing agent particles or liquid during the screening process.

[0023] A fastening rod 35 is threadedly connected to the outer side of one end of the guide block 34, and the end of the fastening rod 35 passes through the guide block 34 and abuts against one end of the storage tank 21; By using threaded transmission, the end of the fastening rod 35 is tightly clamped to the outer surface of the storage tank 21, and the position of the support seat 33 is locked by friction, thus completing the assembly and fixation of the overall structure.

[0024] A conveying pipe 36 is fixedly connected to the top of the storage tank 21. One side of the conveying pipe 36 passes through one side of the detection body 11. An air pump 37 is provided on the outer surface of the conveying pipe 36. A spray head 38 is fixed on the outside of the air pump 37. The air pump 37 transfers the extinguishing agent inside the storage tank 21 to the delivery pipe 36, and then from the delivery pipe 36 to the spray head 38, so that the extinguishing agent can be sprayed out from the spray head at a certain pressure.

[0025] Working principle: First, align the positioning rod 24 of the inclined frame 22 with the preset positioning hole 28 of the feed chute 23 and insert it. Then, push the support base 33 to slide along the guide groove 32 on the outside of the storage tank 21 until the support base 33 is in contact with the bottom of the inclined frame 22. During this process, the extension plate 31 on the outside of the support base 33 moves synchronously with the support base 33. Finally, rotate the fastening rod 35 on the support base 33, and use the threaded transmission to make the end of the fastening rod 35 tightly clamp onto the outer surface of the storage tank 21, locking the position of the support base 33 by friction. When liquid or dry powder extinguishing agent is poured into the inlet, it flows along the inclined surface of the inclined frame 22 under the action of gravity. It first contacts the filter screen 26 on the inner wall of the support frame 25. The filter screen 26 has a preset pore size that is suitable for the type of extinguishing agent, which can intercept impurity particles that exceed the set threshold size. Qualified extinguishing agent components continue to flow downward through the pores of the filter screen 26 and finally fall into the storage tank 21 for collection. The unqualified impurities that are intercepted remain on the surface of the filter screen 26 due to the slope of the inclined frame 22, which is convenient for subsequent manual cleaning or automatic discharge.

[0026] This step solves the problem of transport blockage caused by impurities in extinguishing agents in different physical states, ensures a stable and efficient screening process, and provides a prerequisite guarantee for the accuracy of extinguishing agent performance testing.

[0027] Please see Figure 1 , Figure 2 , Figure 3 , Figure 6 As shown, this embodiment, based on the above embodiment, further includes: The shielding component includes a baffle 41, a chute 42, a slider 44, and a limiting strip 45. The chute 42 is opened at the upper part of both ends of the inner surface of the feed chute 23. The slider 44 is slidably connected to the inside of the chute 42. The baffle 41 is disposed between the two sliders 44 and blocks the inside of the feed chute 23. The limiting strip 45 is fixed to one side of the top of the baffle 41 and is suspended from the top of the storage tank 21. After the inclined frame 22 is installed by the cooperation of the positioning rod 24 and the positioning hole 28, the operator can push the baffle 41 so that the sliders 44 on both sides of the baffle 41 slide vertically downward along the preset sliding groove 42 on the inner wall of the feed trough 23. During this process, the baffle 41 gradually moves down to the upper position of the inner surface of the feed trough 23, forming a shield for the upper space of the feed trough 23. As the baffle 41 moves down, the rubber block 46 at its bottom contacts and is squeezed with the lower slot 43 on the inner wall of the feed trough 23. After the rubber block 46 deforms due to its own elasticity, it is stuck in the lower slot 43, thereby fixing the baffle 41 stably in the lower position. At this time, the baffle 41 can block the splash that may occur when the extinguishing agent is poured in, prevent liquid or dry powder extinguishing agent from overflowing from the upper part of the feed trough 23, and at the same time prevent external impurities from falling into the installed inclined frame 22, ensuring the cleanliness of the screening environment.

[0028] Rubber blocks 46 are glued to the top and bottom of the slider 44. Slots 43 are provided at the top and bottom of the inner surface of the groove 42, and the rubber blocks 46 are engaged inside the slots 43.

[0029] Working principle: The operator can push the baffle 41, causing the sliders 44 on both sides of the baffle 41 to slide vertically downwards along the pre-set grooves 42 on the inner wall of the feed trough 23. During this process, the baffle 41 gradually moves down to the upper position of the inner surface of the feed trough 23. As the baffle 41 moves down, the rubber block 46 at its bottom contacts and is compressed against the lower slot 43 on the inner wall of the feed trough 23. After the rubber block 46 deforms due to its own elasticity, it is locked in the lower slot 43, thus stabilizing the baffle 41 in the lower position. When it is necessary to install or remove the tilting frame 22, the operator lifts the baffle 41 upwards, and the sliders 44 slide upwards along the grooves 42. The baffle 41 rises accordingly, and the rubber block 46 at its top contacts and is compressed against the upper slot 43 on the inner wall of the feed trough 23. After the rubber block 46 deforms elastically, it is locked in the upper slot 43, thus stabilizing the baffle 41 in the upper position.

[0030] This step not only provides effective blocking protection during the extinguishing agent screening process, but also allows for flexible avoidance during the loading and unloading of the inclined frame 22, thereby improving the operational convenience and reliability of the entire device.
