Description

Technical Field

[0001] This utility model relates to a fire protection experimental device, specifically to an experimental device for a fire extinguishing nozzle. Background Technology

[0002] Fine water mist fire extinguishing technology is increasingly widely used in the field of fire protection in specific locations due to its advantages such as high efficiency and water saving, environmental friendliness and cleanliness, and minimal secondary damage to the protected objects.

[0003] The core effectiveness of a fine water mist fire suppression system highly depends on the atomization characteristics of the nozzle and its coverage and extinguishing efficiency under real fire conditions. Therefore, rigorous experimental testing must be conducted before the nozzle is developed, its performance verified, and it is applied in engineering.

[0004] However, current common fine water mist nozzle experimental equipment suffers from a significant technical bottleneck: the nozzles are typically rigidly fixed in a predetermined position and orientation within the experimental setup (such as an experimental chamber or test bench). This fixed installation method leads to serious limitations in experimental simulation.

[0005] First, it cannot dynamically simulate the characteristics of an uncertain fire source location and a variable fire spread direction in a real fire scene. The relative position and angle between the nozzle and the fire source are forcibly locked in the experiment, which makes the interaction between the jet flow field and the flame seriously distorted.

[0006] Secondly, it is impossible to effectively assess the actual spray pattern changes, coverage uniformity, and key fire extinguishing efficiency parameters of the nozzles at different installation heights and angles;

[0007] This fixed nozzle testing method greatly restricts the accurate evaluation and optimization design of the comprehensive performance of fine water mist nozzles in near-real application scenarios, resulting in a significant deviation between experimental data and actual application effects. This has become a key constraint on improving the reliability and applicability of fine water mist fire extinguishing systems, and a technological breakthrough is urgently needed.

[0038] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0039] Example:

[0040] See Figure 1 and Figure 2This embodiment discloses an experimental device for a fire extinguishing nozzle, including a fireproof box 10, a slide rail 20, a support frame 30, and a drive assembly 40. The fireproof box 10 is a box structure with fire-resistant material lining its interior walls and a fire extinguisher mounted on its top. The front of the fireproof box 10 is an openable door panel with fire-resistant glass for observation. Air intake grilles are located on the side walls of the fireproof box 10, and a smoke exhaust duct is located on the top. The central part of the bottom surface of the fireproof box 10 is the ignition zone, where fuel for combustion is placed to simulate a fire.

[0041] The slide rail 20 is installed inside the fireproof box 10, with one end of the slide rail 20 close to the side of the fireproof box 10 and the other end close to the top of the fireproof box 10.

[0042] The support frame 30 is slidably mounted on the slide rail 20, and the support frame 30 is also connected to the water supply pipe 33 and the nozzle 50 used for the experiment.

[0043] The drive assembly 40 is located between the slide rail 20 and the support frame 30, and is used to drive the support frame 30 to move on the slide rail 20.

[0044] In this embodiment, the drive component 40 drives the support frame 30 to move on the slide rail 20, thereby driving the nozzle 50 to move on the slide rail 20, which in turn changes the position between the nozzle 50 and the fire zone, thereby enabling real-time control of the position of the nozzle 50 and improving the simulation accuracy.

[0045] In one specific embodiment:

[0046] The lower part of the fireproof box 10 is equipped with several support rods 11, all of which are made of fireproof material and are spaced apart from the bottom of the fireproof box 10. The aforementioned fire zone is located on the support rods 11.

[0047] The support rod 11 is mainly used to provide an attachment point for the fire zone. In addition, due to the space limitation of the fireproof box 10, the oxygen in the fireproof box 10 will drop relatively quickly. In order to compensate for the problem of insufficient contact between oxygen content and fuel, the support rod 11 is set up so that the bottom of the fuel can effectively contact the air, thereby simulating the fire situation more realistically.

[0048] In another specific embodiment:

[0049] An igniter 12 is installed at the lower part of the fireproof box 10. The igniter 12 is located above the support rod 11, and the ignition end of the igniter 12 is located in the fire zone.

[0050] In this embodiment, by setting up an igniter 12, manual ignition is avoided, thereby improving safety.

[0051] In another specific embodiment:

[0052] The slide rail 20 has an arc-shaped structure with an arc angle of less than or equal to 90°, and its center is located within the fire zone. By setting the slide rail 20 to an arc-shaped structure, the spray tip of the nozzle 50 can always be aimed at the fire zone.

[0053] In another specific embodiment:

[0054] The slide rail 20 has channels running through its top and bottom sides, and tracks running through its left and right sides. For example... Figure 3 As shown, the support frame 30 includes a sliding plate 31 and a support tube 32. The two ends of the sliding plate 31 are slidably disposed in the groove, and the support tube 32 is disposed in the middle of the sliding plate 31. The two ends of the support tube 32 extend out from the channel. The nozzle 50 used for the experiment is installed at one end of the support tube 32, and the water supply pipe 33 is installed at the other end of the support tube 32.

[0055] The aforementioned drive component 40 is poweredly connected to the skateboard 31.

[0056] In another specific embodiment:

[0057] The drive assembly 40 includes a rack 41, a motor 42, and a gear 43. The rack 41 is arc-shaped and is mounted on an arc-shaped slide rail 20. The motor 42 is fixedly mounted on the slide plate 31, and the gear 43 is mounted on the output shaft of the motor 42, meshing with the rack 41.

[0058] During operation, motor 42 drives gear 43 to rotate, thereby moving motor 42 and support frame 30 on slide rail 20. By controlling the forward and reverse rotation of motor 42, the specific position of nozzle 50 on slide rail 20 is controlled.

[0059] In another preferred embodiment, the support frame 30 further includes a fire baffle 34, which is disposed on the support tube 32 and can shield the drive assembly 40. The fire baffle 34 is provided to protect the drive assembly 40.

[0060] In another preferred embodiment, the water supply pipe 33 is a corrugated pipe made of metal, which gives the water pipe a certain degree of flexibility and fire resistance.

[0061] In another preferred embodiment, a reducer is provided between the motor 42 and the gear 43 to increase the output torque of the motor 42.

[0062] In another preferred embodiment, the drive assembly 40 is wrapped with heat-insulating and fire-resistant material.

[0063] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
