Description

Technical Field

[0001] This utility model relates to a fire extinguishing test device, and in particular to a perfluorohexanone agent fire extinguishing test device applied in the field of fire extinguishing experiments. Background Technology

[0002] Perfluorohexanone is a widely recognized and used clean gas extinguishing agent designed to replace traditional halon extinguishing agents because it has zero ozone depletion potential, low atmospheric lifetime and greenhouse effect potential, and is more environmentally friendly. It is suitable for protecting precision electronic equipment, data centers, communication facilities, control rooms, museums, archives and other places where fire extinguishing requires no residue, no conductivity and no damage to equipment.

[0003] When conducting fire extinguishing experiments, a combustion platform is usually set up inside the test chamber to simulate flat-plane fire. For example, Chinese Patent Publication No. CN119779900A discloses a test device and method for testing the fire extinguishing performance of a water-based forest fire extinguishing agent. This patent includes a combustion support and a metal mesh to facilitate the combustion of the fire source. Another example is Chinese Patent Publication No. CN116242957A, which discloses a test device and method for testing the performance of an alkali metal fire extinguishing agent. This patent includes a combustion plate for placing alkali metals, and it also only includes one combustion structure.

[0004] Perfluorohexanone is suitable for places such as data center cabinets or warehouse shelves. Most of the fire sources in these places are three-dimensional fire sources. When conducting tests using the aforementioned patents, the concentration difference between the layers of the three-dimensional fire source is large. The interlayer plates of the central cabinet or shelf can easily block the spray path, resulting in a shielding effect. The planar fire source test equipment is difficult to simulate real fire scenarios such as cabinets, which affects the test results. Summary of the Invention

[0005] The technical problem that this utility model aims to solve in view of the above-mentioned prior art is that perfluorohexanone agents are suitable for places such as data centers, which are usually three-dimensional fire sources. However, existing test equipment is mostly for two-dimensional fire sources, which makes it difficult to simulate real fire scenarios and affects the accuracy of test data.

[0006] To address the aforementioned problems, this utility model provides a perfluorohexanone fire extinguishing test device, comprising a shell, with support legs fixedly connected to the four corners of the lower end of the shell, and a base plate fixedly connected to the lower ends of multiple support legs. A protective door is rotatably connected to the front end of the shell. Four support rods are fixedly connected to the inner bottom wall of the shell, and three combustion platforms are fitted around the support rods. A combustion plate is placed on the upper end of each combustion platform. Two positioning rings are fixedly connected to the inner cavity of the support rods, and a sliding plate is provided between the two positioning rings. A telescopic tube is fixedly connected between the sliding plate and the positioning rings. A positioning block is fixedly connected to the outer surface of the sliding plate. A groove is carved into the surface of the support rod, and the end of the positioning block away from the sliding plate moves through the groove and is fixedly connected to the combustion platform in the middle. The lower end of the sliding plate... A top rod is fixedly connected, and the lower end of the top rod movably passes through the positioning ring below and is fixedly connected to a top plate. The lower end of the top plate movably passes through the housing and is fixedly connected to an electric cylinder. The lower end of the electric cylinder is fixedly connected to a base plate. A storage box is placed on the upper end of the base plate. A baffle is fixedly embedded on the right end of the housing, and two support plates are fixedly connected to the right end of the housing. A motor is fixedly connected to the upper end of the upper support plate. The output end of the motor movably passes through the support plate and is fixedly connected to a screw. A lifting block is threaded on the outer surface of the screw. A flow pump is fixedly connected to the right end of the storage box. A drain pipe is fixedly connected to the drain port of the flow pump. A nozzle is fixedly connected to the end of the drain pipe away from the flow pump. The end of the nozzle away from the drain pipe is fixedly connected to the lifting block and the baffle.

[0007] In the aforementioned perfluorohexanone fire extinguishing test equipment, compared with the existing planar fire source test equipment, this application uses a central adjustable combustion platform to adjust the distance between the three combustion platforms, simulating the interlayer shielding effect in a three-dimensional fire source, thereby simulating a real fire scenario, making it convenient for staff to conduct tests according to actual conditions, and thus effectively improving the integrity of test data.

[0008] As a further supplement to this application, the combustion platform located in the middle is slidably sleeved on the outer surface of the four support rods, while the other two combustion platforms are fixedly sleeved on the outer surface of the four support rods.

[0009] As a further supplement to this application, an observation window is fixedly embedded in the front end of the protective door, and an image acquisition module is installed inside the housing. The image acquisition module, electric cylinder, motor and flow pump are all connected to an external controller signal.

[0010] As a further supplement to this application, the diameters of the slide plate and the top plate are both consistent with the inner diameter of the support rod, and the diameter of the top rod is smaller than the inner diameter of the positioning ring.

[0011] As a further addition to this application, the baffle is made of an elastic material, and the left end of the lifting block slides in contact with the right end of the housing.

[0012] As a further addition to this application, the nozzle is placed at a downward tilt, and the drain pipe is a telescopic flexible hose.

[0013] As a further supplement to this application, an exhaust pipe is fixedly connected to the upper end of the housing, and an axial flow fan is installed inside the exhaust pipe.

[0014] In summary, in practical applications, the material to be burned is placed inside the combustion pan, and the agent inside the storage tank is pumped into the nozzle by a flow pump to spray the fire source inside the combustion pan, thereby conducting a fire extinguishing test. When it is necessary to adjust the distance between the combustion pans, the electric cylinder can be activated to extend or retract, causing the top plate to push the top rod to move up and down, which in turn moves the sliding plate up and down, causing the central combustion platform to move up and down, thereby adjusting the distance between the three combustion platforms. This allows the staff to adjust according to the actual situation, thus simulating fire locations with three-dimensional fire sources such as server racks and warehouses, effectively improving the accuracy of the test data.

Detailed Implementation

[0017] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0018] First implementation method: Figure 1The diagram shows a perfluorohexanone fire extinguishing test device, comprising a housing 1. Support legs are fixedly connected to the four lower corners of the housing 1. A base plate 2 is fixedly connected to the lower ends of the multiple support legs. A storage tank 14 is placed on the upper end of the base plate 2. A flow pump 19 is fixedly connected to the right end of the storage tank 14. Those skilled in the art can select a suitable model of flow pump 19 according to actual needs, such as XBD7.6 / 5W. A drain pipe 20 is fixedly connected to the drain port of the flow pump 19, allowing the flow pump 19 to pump the agent into the drain pipe 20. A protective door is rotatably connected to the front end of the housing 1. An observation window is fixedly embedded in the front end of the protective door. The observation window is made of a high-temperature resistant transparent material, facilitating observation of the interior of the housing 1 by personnel. An image acquisition module is installed inside the housing 1. The image acquisition module can be configured to continuously acquire flame information images, enabling personnel to evaluate the fire extinguishing information based on the flame information. This is prior art and will not be described in detail here. The image acquisition module, electric cylinder 13, motor 16, and flow pump 19 are all connected to an external controller.

[0019] Figures 2-5 The diagram shows that: four support rods 3 are fixedly connected to the inner bottom wall of the shell 1. Three combustion platforms 4 are fitted around the support rods 3. The middle combustion platform 4 is slidably fitted onto the outer surface of the four support rods 3, while the other two combustion platforms 4 are fixedly fitted onto the outer surface of the four support rods 3. A combustion plate 5 is placed on the upper end of the combustion platform 4. A heating element is provided inside the combustion plate 5. After the object to be burned is placed inside the combustion plate 5, it is heated and burned by the heating element. Two positioning rings 6 are fixedly connected to the inner cavity of the support rods 3. A sliding plate 7 is provided between the two positioning rings 6. A telescopic tube 8 is fixedly connected between the sliding plate 7 and the positioning rings 6. A positioning block 9 is fixedly connected to the outer surface of the sliding plate 7. A groove 10 is carved into the surface of the support rods 3. The end of the positioning block 9 away from the sliding plate 7 moves through the groove 10 and is fixedly connected to the middle combustion platform 4. A combustion plate 4 is fixedly connected to the lower end of the sliding plate 7. The top rod 11 has its lower end movably passing through the positioning ring 6 below and fixedly connected to the top plate 12. The diameters of the slide plate 7 and the top plate 12 are both the same as the inner diameter of the support rod 3. The diameter of the top rod 11 is smaller than the inner diameter of the positioning ring 6. The lower end of the top plate 12 movably passes through the housing 1 and is fixedly connected to the electric cylinder 13. Those skilled in the art can select a suitable model of electric cylinder 13 according to actual needs, such as DYTZ. The lower end of the electric cylinder 13 is fixedly connected to the bottom plate 2. The electric cylinder 13 extends or retracts, causing the top plate 12 to push the top rod 11 to move up and down, thereby driving the slide plate 7 to move up and down. The two telescopic tubes 8 located at the upper and lower ends of the slide plate 7 can move up and down with the movement of the slide plate 7, thereby effectively preventing flame overflow. The combustion platform 4 in the middle also moves up and down with the movement of the slide plate 7, thereby adjusting the distance between the three combustion platforms 4.

[0020] Figure 1 and Figure 6 The diagram shows that a baffle 15 is fixedly embedded at the right end of the housing 1. The baffle 15 is made of elastic material, and two support plates are fixedly connected to the right end of the housing 1. A motor 16 is fixedly connected to the upper end of the upper support plate. Those skilled in the art can select a suitable model of motor 16 according to actual needs, such as Y2-63M1-2-0.18KW. The output end of the motor 16 movably passes through the support plate and is fixedly connected to a screw 17. A lifting block 18 is threaded on the outer surface of the screw 17. The left end of the lifting block 18 slides in contact with the right end of the housing 1. The drain pipe 20 is away from the flow path. One end of the pump 19 is fixedly connected to a nozzle 21. The end of the nozzle 21 away from the drain pipe 20 is fixedly connected through the lifting block 18 and the baffle 15. The nozzle 21 is placed at a downward tilt. The drain pipe 20 is a telescopic hose. The motor 16 drives the screw 17 to rotate, thereby driving the lifting block 18 to move up and down to adjust the up and down movement of the nozzle 21. Adjusting the position of the nozzle 21 makes it easier to extinguish the fire source inside the combustion plate 5. The baffle 15 extends and retracts with the up and down movement of the nozzle 21, effectively preventing the flame from overflowing. The drain pipe 20 of the telescopic hose can move with the movement of the nozzle 21.

[0021] All parts located inside the housing 1 are made of high-temperature resistant materials, thereby extending the service life of the equipment.

[0022] During fire extinguishing experiments, the material to be burned can be placed inside the combustion pan 5. The agent inside the storage tank 14 is pumped to the nozzle 21 by the flow pump 19 to spray the fire source inside the combustion pan 5, thus conducting the fire extinguishing experiment. When it is necessary to adjust the spacing between the combustion pans 5, the electric cylinder 13 can be activated to extend or retract, causing the top plate 12 to push the top rod 11 up and down, thereby driving the slide plate 7 up and down, causing the central combustion platform 4 to move up and down, thereby adjusting the spacing between the three combustion platforms 4, simulating the interlayer shielding effect in a three-dimensional fire source, which is convenient for staff to adjust according to the actual situation, thus simulating fire locations with three-dimensional fire sources such as cabinets and warehouses. When extinguishing the fire, the motor 16 can be activated to drive the screw 17 to rotate, thereby driving the lifting block 18 up and down to adjust the position of the nozzle 21, which facilitates the extinguishing of the fire source inside the combustion pan 5. The baffle 15 extends and retracts with the up and down movement of the nozzle 21, effectively preventing flame overflow, thereby effectively improving the accuracy of the test data.

[0023] Second implementation method: This embodiment adds an axial flow fan 22 to the first embodiment, while the rest remains the same as the first embodiment.

[0024] Figure 7As shown: an exhaust pipe is fixedly connected to the upper end of the housing 1, and an axial flow fan 22 is installed inside the exhaust pipe. Those skilled in the art can select a suitable model of axial flow fan 22 according to actual needs, such as HTF.

[0025] During fire extinguishing tests, the axial flow fan 22 can be started to quickly exhaust the fire extinguishing exhaust gas, making it easier for staff to observe the fire extinguishing situation inside the casing 1.

[0026] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
