Description

Technical Field

[0001] This utility model relates to the field of fire detection technology, specifically to a multi-compartment demonstration box for an early-stage pyrolysis particle fire detector. Background Technology

[0002] Early-stage pyrolysis particle fire detectors are used for detecting very early-stage fires. To demonstrate their effectiveness, they often need to be transported to different locations for demonstrations. However, fire detectors are typically suspended from ceilings or other locations, making such demonstrations extremely inconvenient. Therefore, our company has designed a portable fire detector demonstration case. During demonstrations in multiple locations, various types of combustible materials should be used, such as dry wood, pure cotton fabric, electrical wire insulation, or circuit boards. These materials can be demonstrated in multiple compartments or within a single compartment.

[0003] However, a single chamber cannot simultaneously simulate multiple real fire environments that generate pyrolysis particles. Furthermore, different combustibles produce pyrolysis particles at different times, with varying concentrations and leaving different combustion residues. For example, wood combustion produces pyrolysis particles very early and leaves no stubborn residue, making it easy to clean. Cables made of PVC, on the other hand, may produce stubborn residues. Circuit boards, being heavily polluting materials, produce highly corrosive, sticky, toxic, or semi-volatile residues after combustion, which adhere to the inner walls of the chamber or the surface of sensors, making them difficult to remove completely. Therefore, demonstrating different combustibles sequentially within the same chamber not only requires time and effort to clean the residues but may also affect the results of subsequent demonstrations. Thus, a demonstration chamber with multiple demonstration chambers is needed. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a multi-compartment demonstration box for very early pyrolysis particle fire detectors. By setting up several non-interfering reaction compartments, each containing a fire detector, the invention achieves the purpose of simultaneous demonstration and comparison of multiple reaction compartments, while ensuring the accuracy of the results.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a multi-compartment demonstration box for an early pyrolysis particle fire detector, comprising a base, a multi-compartment detection structure placed on top of the base, and a fire simulation structure disposed inside the base and directly below the multi-compartment detection structure;

[0006] The fire simulation structure includes a fire simulation space opened on the upper surface of the base, and a base heating module set inside the fire simulation space.

[0007] The multi-compartment detection structure includes a compartment located directly above and covering the fire simulation space, several partitions vertically installed inside the compartment that divide the compartment into several independent spaces, ventilation holes at the bottom of the compartment corresponding to each independent space, and fire detectors installed inside the compartment corresponding to each independent space.

[0008] Furthermore, the chamber includes a base plate laid on the upper surface of the base and covering the top of the fire simulation space, side plates vertically arranged around the edge of the base plate, and a cover plate set on the top of the side plates; a vacuum suction cup is fixedly connected to the upper surface of the fire detector, and the fire detector is fixedly connected to the cover plate through the vacuum suction cup; both the chamber and the partition plate are made of transparent material.

[0009] Furthermore, the base heating module includes a first support plate that is detachably and fixedly connected to the bottom of the fire simulation space, and a heating rod disposed on the first support plate; the heating rod is connected to a wire for power supply and heating.

[0010] Furthermore, the base plate includes several support plates arranged sequentially in the left-right or front-back direction; ventilation holes are opened on the support plates; a locking joint is provided between any two adjacent support plates, and there is at least one locking joint; the partition plate includes a baffle that is vertically engaged with the locking joint.

[0011] Furthermore, the partition plate also includes several partitions spaced apart along the length of the baffle on both sides; the partitions and the baffle are detachably and fixedly connected.

[0012] Furthermore, the base is equipped with a display screen, a heating module switch, and a power switch, with the display screen connected to the fire detector.

[0013] Furthermore, a plug is inserted into the vent hole; the plug is inserted into the bottom of the clamp.

[0014] Furthermore, the top of the clip extends beyond the top of the plug cylinder, and the portion of the clip extending beyond the plug cylinder is provided with external threads; the clip is connected to a second support plate via the external threads; a heating rod is provided on the second support plate.

[0015] The beneficial effects of this utility model are as follows: By setting up several non-interfering reaction chambers, each of which is connected to a fire detector via an airflow pipe to deliver an airflow containing pyrolysis particles, the purpose of simultaneous combustion demonstration and comparison of multiple reaction chambers is achieved; moreover, the demonstration process does not interfere with each other, the result data is highly accurate, and time and effort are saved; if difficult-to-remove residues are generated, the use of that reaction chamber can be temporarily abandoned, and then a new reaction chamber can be added to continue the demonstration, improving demonstration efficiency and providing a better customer experience; the adjustable chamber space setting is used to compare the detection effects of fire detectors in spaces of different sizes; For example, some fire detectors are installed in small spaces such as electrical distribution cabinets, while others are installed in the room where the electrical distribution cabinet is located. The time that these fire detectors in different locations can detect a fire is different. This time corresponds to the degree of combustion of the burning material. The acceptable degree of combustion determines whether a fire detector should be installed accordingly. For example, if the degree of combustion is acceptable when a fire is detected, there is no need to install a fire detector for that burning material, such as inside the electrical distribution cabinet. It is only necessary to install one in the room where the electrical distribution cabinet is located. If it is unacceptable, then a detector needs to be installed inside the electrical distribution cabinet. Installing a detachable tray can improve the efficiency of residue handling, thereby improving the efficiency of demonstration. Attached Figure Description

[0025] Example:

[0026] like Figures 1-6 As shown, a multi-compartment demonstration box for an early pyrolysis particle fire detector includes a base 1, a multi-compartment detection structure placed on top of the base 1, and a fire simulation structure disposed inside the base 1 and directly below the multi-compartment detection structure.

[0027] The fire simulation structure includes a fire simulation space 5 extending downward from the upper surface of the base 1, and a base heating module disposed inside the fire simulation space 5.

[0028] The multi-compartment detection structure includes a compartment located directly above and covering the fire simulation space 5, several partitions vertically arranged inside the compartment and interconnected to divide the compartment into several independent spaces, ventilation holes 16 corresponding to each independent space at the bottom of the compartment, and fire detectors 21 corresponding to each independent space installed inside the compartment. The fire detectors 21 use small cloud chamber type fire detectors, such as the ZW-PTS series, which use advanced optical scattering detection technology and adopt a point-type design concept. They have the advantages of small size, light weight, and high integration, and can be wall-mounted or ceiling-mounted in narrow and numerous spaces such as indoor rooms and inside electrical distribution cabinets.

[0029] like Figure 1 As shown, the direction where the display screen 2 is located is defined as the front, and other directions are determined at the same time; the support plate 9 and the baffle 11 are both rectangular plates. The width direction of the support plate 9 is its extension direction, the width direction of the baffle 11 is the vertical direction, and the length direction is the direction where the slot 10 is located, which also corresponds to the length direction of the support plate 9.

[0030] The chamber includes a base plate laid on the upper surface of the base 1 and covering the top of the fire simulation space 5, side plates 14 vertically arranged around the edge of the base plate, and a cover plate 15 set on the top of the side plates 14; the cover plate 15 can be directly placed on the top of the side plates 14, or it can be fixed to the side plates 14 by a snap-fit ​​structure, etc.; a vacuum suction cup 22 is fixedly connected to the upper surface of the fire detector 21, and the fire detector 21 is fixedly connected to the cover plate 15 through the vacuum suction cup 22; the chamber and the partition plate are made of transparent materials, such as acrylic sheets, so as to facilitate external observation.

[0031] The base heating module includes a first support plate 6 that is detachably and fixedly connected to the bottom of the fire simulation space 5, and a heating rod 7 set on the first support plate 6; the heating rod 7 is connected to a wire 8 for powering it for heating.

[0032] The base plate includes several support plates 9 arranged sequentially in the left-right or front-back direction; ventilation holes 16 are opened on the support plates 9; the sum of the widths of all support plates 9 is less than the distance between two opposite side plates 14 in the direction in which the support plates 9 are arranged; a locking slot 10 is provided between any two adjacent support plates 9, and there is at least one locking slot 10; the partition plate includes a baffle 11 vertically locked in the locking slot 10, the top of the baffle 11 abuts against the cover plate 15, and the two sides of the baffle 11 are clamped by the support plates 9 on both sides. In order to ensure sealing, a sealing strip is provided on the side of the baffle 11 that is locked with the support plate 9, and a sealing strip can also be provided on the top of the baffle 11 to prevent different detection spaces from being connected in series.

[0033] The partition also includes several partitions spaced at intervals along the length of both sides of the baffle 11; the number and spacing of the partitions on both sides are arbitrary and do not interfere with each other, and both sides of the partitions are connected to the side plate 14 or other partitions and sealed; the partitions are detachably and fixedly connected to the baffle 11; specifically, such as Figure 2 and Figure 3 As shown, there is one baffle 11. On the right side of the baffle 11 and the corresponding side plate 14, a set of left and right corresponding first fixing strips 23 are fixedly installed along their length. The first fixing strip 23 is composed of two locking strips with a front-to-back gap. A first partition 12 is snapped or inserted into the first fixing strip 23. On the left side of the baffle 11 and the corresponding side plate 14, two sets of left and right corresponding second fixing strips 24 are fixedly installed along their length. The second fixing strip 24 is also composed of two locking strips with a front-to-back gap. A second partition 13 is snapped or inserted into the second fixing strip 24. At this time, the space inside the chamber is divided into several independent spaces by the baffle 11, the first partition 12 and the second partition 13, and detected independently. A fire detector 21 is installed on the lower surface of the top cover plate 15 in each independent space separated by the above structure, so that multiple chambers can be demonstrated at the same time, and demonstrations of different ignition times and different burning materials can be displayed.

[0034] The base 1 is equipped with a display screen 2, a heating module switch 3, and a power switch 4. The display screen 2 is wirelessly connected to the fire detector 21 to display the detection results of the fire detector 21. The base 1 is equipped with a connector. The other end of the wire 8 is connected to the end of the connector located inside the base 1, and the end of the connector located outside the base 1 is connected to an external power source through a connecting wire. There are several sockets at the connector. The sockets are connected not only to the wire 8 connected to the heating rod 7, but also to other wires connected to the display screen 2 and other electrical components. The power switch 4 is located at the connector to control the power supply to all wires (wire 8 and other wires) at that location, thereby realizing the power supply to the entire demonstration box.

[0035] A plug cylinder 17 is snapped into the vent hole 16. The main body of the plug cylinder 17 is a cylindrical structure with a closed bottom. A retaining ring is integrally fitted on the outer side of the top of the cylindrical structure. The outer diameter of the retaining ring is larger than the diameter of the vent hole 16 to prevent the plug cylinder 17 from falling out of the vent hole. The plug cylinder 17 is inserted into the bottom of the clamp 18. The clamp 18 is set to improve the connection stability between the plug cylinder 17 and the vent hole 16. The plug cylinder 17 and the clamp 18 are set to prevent pyrolysis particles from entering when no test object is needed in this independent space, thereby affecting other independent spaces that need to be tested.

[0036] The top of the clip 18 extends beyond the top of the plug cylinder 17, and the portion of the clip 18 extending beyond the plug cylinder 17 is provided with external threads. The clip 18 is connected to the second support plate 19 via the external threads. Specifically, a sleeve 20 is provided on the lower surface of the second support plate 19, and an internal thread adapted to the external threads is provided on the inner wall of the sleeve 20. The sleeve 20 and the clip 18 are fixed by the engagement of the internal and external threads. A heating rod 7 is provided on the second support plate 19. Each heating rod 7 is connected to a wire 8, and each wire 8 can be individually equipped with a heating module switch 3 to control the on / off state of the power supply. That is, each wire 8 is divided into two segments: one segment connects the heating rod 7 to the heating module switch 3, and the other segment connects the heating module switch 3 to the connector socket. Alternatively, all the wires 8 connected to the heating rods 7 are controlled by the same heating module switch 3 to control the on / off state of the heating rods 7. That is, each heating rod 7 is connected to the same heating module switch 3 via a wire 8, but the other end of the heating module switch 3 is connected to only one wire, which connects the heating module switch 3 to the connector socket.

[0037] There are two optional operating methods. The first is to ignite the combustible material in the fire simulation space 5, in which case the second support plate 19 is not installed on the top of the clip 18. The second is to ignite the combustible material in each independent space, in which case the second support plate 19 is installed on the top of the clip 18. If only one type of combustible material is to be ignited, either the first or second operating method can be selected, or the demonstration can be carried out sequentially, and the demonstration process and results can be observed and recorded. The plug 17 and the clip 18 are inserted into the vent hole 16 of the independent space where no demonstration is required. If multiple combustible materials are to be ignited, the demonstration can be carried out sequentially in the fire simulation space 5, but generally, different independent spaces are selected. In this case, the plug 17 is inserted into the vent hole 16, the second support plate 19 is installed on the top of the clip 18, and the combustible material is ignited on it. The positions of the first partition 12 and the second partition 13 can be adjusted as needed. Two opposing first fixing strips 23 form one group, and two opposing second fixing strips 24 form another group. The number of groups of first fixing strips 23 is greater than the number of first partitions 12, and the number of groups of second fixing strips 24 is greater than the number of second partitions 13. This facilitates changing the positions of the first partitions 12 and the second partitions 13, thereby adjusting the size of each independent space for comparative demonstration. During heating, turn on the power switch 4, set the desired temperature for the object to be heated, and turn on the heating module switch 3 to begin the demonstration. The base heating module is also equipped with a digital temperature controller, heating rods, thermocouples, etc., to provide controllable high-temperature simulation for the object to be tested. These components are all existing technologies.

[0038] The above description is only used to illustrate the technical solution of this utility model and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
