[0047] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore detailed descriptions of them will be omitted. Furthermore, the drawings are merely illustrative of this disclosure and are not necessarily drawn to scale.
[0048] Although relative terms such as "up" and "down" are used in this specification to describe the relative relationship of one component of an icon to another, these terms are used only for convenience, such as according to the orientation of the examples shown in the accompanying drawings. It is understood that if the device of the icon is flipped upside down, the component described as "up" will become the component described as "down." When a structure is "up" of another structure, it may mean that the structure is integrally formed on the other structure, or that the structure is "directly" mounted on the other structure, or that the structure is "indirectly" mounted on the other structure through another structure.
[0049] The terms “a,” “one,” “the,” “the,” and “at least one” are used to indicate the presence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended inclusion meaning and that there may be other elements / components / etc. in addition to the listed elements / components / etc.; the terms “first,” “second,” etc. are used only as markers and are not a limitation on the number of objects or their order.
[0050] In this application, unless otherwise expressly specified and limited, the term "connection" shall be interpreted broadly. For example, "connection" may be a fixed connection, a detachable connection, or an integral part; it may be a direct connection or an indirect connection through an intermediate medium.
[0051] Many performance venues and stages utilize flame-throwing systems to enhance the viewing experience or as part of the performance itself. These performances are spectacular and engaging, attracting a large audience and enriching their lives. To ensure safety, the flame-throwing nozzles of these systems are protected by a protective casing. During performances, situations frequently arise where the nozzles fail to ignite. In such cases, staff must urgently replace the fuel nozzles during breaks between shows. This replacement requires removing and installing the nozzle from the top of the protective casing, making it difficult to place tools on the nozzle to be replaced. The process is extremely challenging, time-consuming, and labor-intensive, making it very inconvenient for emergency repairs during a performance.
[0052] To address the aforementioned issues, this disclosure provides a fire-breathing performance system that can improve the efficiency of changing the nozzle 20, speed up the replacement time, and ensure high safety.
[0053] In one embodiment of this disclosure, see [link to relevant documentation]. Figure 1 The fire-breathing performance system includes a fuel supply unit, a first pipe 7, an ignition unit 1, and a pressure relief unit. The fuel supply unit can stably supply fuel to the ignition unit 1 through the first pipe 7. After the fuel is supplied, the ignition unit 1 can ignite and perform the fire-breathing show. After the performance is completed, the pressure relief unit can release pressure from the ignition unit 1 and the fuel supply unit to ensure the safety of the entire fire-breathing performance system.
[0054] In one embodiment of this disclosure, see [link to relevant documentation]. Figure 1 The feeding unit includes a support frame 28, a material bin 4, a pressurizing pump 3, and a pressure booster and stabilizer assembly 2. The material bin 4 is mounted on the support frame 28, the pressurizing pump 3 is located at the lower end of the material bin 4, and the input end of the pressurizing pump 3 is connected to the lower end of the material bin 4 via a second pipe 5. A first valve 8 is installed on the second pipe 5. The output end of the pressurizing pump 3 is connected to the input end of the pressure booster and stabilizer assembly 2 via a third pipe 6. The output end of the pressure booster and stabilizer assembly 2 is connected to a first pipe 7. In this example, both the second pipe 5 and the third pipe 6 are flexible hoses.
[0055] Optionally, fuel bin 4 stores fuel. In one embodiment of this disclosure, fuel bin 4 may include multiple sub-fuel bins, with their lower ends connected in series, allowing fuel in each sub-fuel bin to be interconnected and simultaneously supplying fuel to ignition unit 1. In another embodiment of this disclosure, fuel bin 4 includes multiple sub-fuel bins, with their lower ends connected in parallel, allowing fuel in one sub-fuel bin to be used up before another sub-fuel bin is opened, achieving relay use of fuel in each sub-fuel bin. In this disclosure, setting multiple sub-fuel bins increases the fuel storage area, ensuring the sustainability of the performance and avoiding performance errors due to fuel shortages.
[0056] Each sub-tank is equipped with a level gauge (not shown in the figure) to monitor the fuel level in each sub-tank, allowing for timely replenishment of fuel or replacement of the sub-tank. In one example, the flamethrower system also includes a control unit. The level gauges are electrically connected to the control unit, and the data collected by the level gauges can be uploaded to the control unit. When the fuel level in a sub-tank reaches the lower limit, the control unit can issue an alarm.
[0057] Optionally, the pressure pump 3 is located at the lower end of the material box 4, which can reduce power consumption and save costs.
[0058] Optionally, a pressure gauge P is also installed on the second pipe 5 to detect the pressure inside the second pipe 5.
[0059] Optional, see Figure 4 The booster and regulator group 2 can include multiple boosters and regulators, which can be connected in series to ensure stable fuel delivery.
[0060] In one embodiment of this disclosure, see [link to relevant documentation]. Figure 1 There are multiple ignition units 1, and each ignition unit 1 shares the same feeding unit, which can save costs.
[0061] See in this example. Figure 1 and Figure 6 The first pipe 7 may include a first sub-pipe 72 and multiple second sub-pipes 71. Each second sub-pipe 71 is configured to correspond one-to-one with each ignition unit 1. The first end of the first sub-pipe 72 is connected to the output end of the booster regulator group 2, and the second end of the first sub-pipe 72 is connected to the first end of each second sub-pipe 71. The second end of each second sub-pipe 71 is connected to the corresponding nozzle 20 of the ignition unit 1, supplying fuel to the corresponding nozzle 20. In this example, each second sub-pipe 71 may be equipped with a second valve (not shown in the figure) to control the flow rate within each second sub-pipe 71.
[0062] In one embodiment of this disclosure, see [link to relevant documentation]. Figure 1 and Figure 2 The ignition unit 1 includes a support base, a nozzle 20, an igniter structure 21, a protective shell, and a protective structure.
[0063] Optional, see Figure 1 and Figure 2The support base includes a base 23, a column 24, and a support platform 29. The column 24 is mounted on the base 23, the support platform 29 is located on the side of the column 24 away from the base 23, and the nozzle 20 is located on the side of the support platform 29 away from the column 24. The support base has a through hole extending from the base 23 to the column 24 and the support platform 29. In other words, the base 23 may have a first through hole, the column 24 may have a second through hole, and the support platform 29 may have a third through hole. The first through hole, the second through hole, and the third through hole are connected in sequence to form a through hole. The second end of the second sub-pipe 71 passes through the through hole and connects to the nozzle 20 located on the support platform 29.
[0064] In this embodiment of the disclosure, the column 24 has a first region and a second region, and the base 23 and the first region of the column 24 are located underwater.
[0065] Optionally, the first sub-pipe 72 and the second sub-pipe 71 of the first pipe 7 are flexible hoses.
[0066] Optional, see Figure 2 The igniter structure 21 is mounted on the support platform 29. When fuel is supplied by the nozzle 20, the igniter structure 21 can ignite the fuel to achieve a fire-breathing performance. In this example, the first end of the igniter structure 21 is fixed to the support platform 29, and the second end of the igniter structure 21 is positioned higher than the nozzle 20.
[0067] In one embodiment of this disclosure, see [link to relevant documentation]. Figure 2 and Figure 3 A mounting base is provided on the support platform 29. The mounting base includes a mounting frame 27 and a second annular grid 11. The mounting frame 27 is provided on the support platform 29 and surrounds the lighter structure 21. It can be understood that the lighter structure 21 is located in the inner ring of the mounting frame 27. The second annular grid 11 is provided on the mounting frame 27 away from the base 23 and surrounds the lighter structure 21.
[0068] In one example, the outer edge of the second annular grid 11 may have a first boss, and the mounting bracket 27 has a second boss at the corresponding position. The first boss and the second boss are bolted together to fix the second annular grid 11 to the mounting bracket 27. In this way, it is convenient to disassemble and replace the second annular grid 11.
[0069] In one embodiment of this disclosure, see [link to relevant documentation]. Figure 2 The protective shell is mounted on the mounting base and surrounds the igniter structure 21. The end of the protective shell away from the support platform 29 is positioned higher than the second end of the igniter structure 21, so that the flame of the ignition unit 1 is contained within the protective shell as much as possible. In this way, the protective shell can protect the igniter structure 21, reduce the risk of accidental activation, improve safety, and enhance the aesthetics of the flame-throwing performance system.
[0070] See this public example. Figure 2 and Figure 3 The protective shell includes a first annular grid 16, a first grid bar group, and a second grid bar group. Each second grid bar 15 in the second grid bar group is connected at one end to the first annular grid 16 and at the other end to the second annular grid 11. The second grid bar group contains multiple second grid bars 15, with specific dimensions determined according to the specific size. Each first grid bar 12 in the first grid bar group is connected at one end to the first annular grid 16 (wherein, when one end of the first grid bar 12 is connected to the first annular grid 16, it is necessary to ensure that the first grid bar 12 is movable), and the other end is movable. The first grid bar 12 has a first position and a second position. In the first position, the first grid bar 12 and the second grid bar 15 are parallel, and the distance between each first grid bar 12, between each second grid bar 15, and between the first grid bar 12 and the second grid bar 15 is less than the diameter of the nozzle 20. In the second position, the first grid bar 12 and the second grid bar 15 intersect, allowing the nozzle 20 to pass through the annular shell from the position of the first grid bar 12. In this disclosure, different grid strips are used to form a protective shell, and gaps exist between each grid strip. This allows the protective shell to not only provide protection but also to allow observation of the flame's state through these gaps, enabling assessment of any malfunctions in the fire-breathing performance system. Furthermore, this disclosure specifies that the second grid strips 15 are fixedly connected, while the first grid strips 12 are movably connected and have a first position and a second position. When maintenance is not required, the first grid strip 12 is in the first position, parallel to the second grid strips 15, ensuring the integrity and aesthetics of the protective shell. When maintenance is required, the first grid strip 12 is manually pushed to the second position, increasing the width of the two gaps on either side of the first grid strip 12. These gaps allow the nozzle 20 to pass through for replacement and maintenance. Using the protective shell of this disclosure, the nozzle 20 can be removed or placed from the side, ensuring safety and reducing maintenance time, thus guaranteeing the smooth operation of the performance.
[0071] In one embodiment of this disclosure, see [link to relevant documentation]. Figure 2 There are two first annular grids 16. The two first annular grids 16 are arranged in sequence along the direction away from the support platform 29. The distance between the first annular grid 16 at the lower end and the base 23 is greater than the distance between the end of the nozzle 20 away from the base 23 and the base 23, so as to ensure that the first annular grid 16 will not interfere with the removal of the nozzle 20 while ensuring a stable connection between the grid bars.
[0072] Each second grid bar 15 has one end connected to two first annular grids 16 and the other end connected to a second annular grid 11. Each first grid bar 12 has one end connected only to the upper first annular grid 16, and the other end is movably disposed. In this disclosure, providing two first annular grids 16 can increase the stability of the protective shell connection.
[0073] Optional, see Figure 2 Each of the second grid bars 15 is connected to the first annular grid 16 by fixing bolts 19, and each of the second grid bars 15 is connected to the second annular grid 11 by fixing bolts 19. The fixing method using fixing bolts 19 is convenient for assembly, does not increase costs, has high versatility, and is easy to replace after damage.
[0074] In one example, the number of first bars 12 in the first bar group is one. In other words, the protective shell includes one first bar 12; see [link to relevant documentation]. Figure 3 and Figure 4 The first grid bar 12 has a notch 13 on one side near at least one of the second annular grid 11 and the first annular grid 16 located at the lower end. The second annular grid 11 and the first annular grid 16 located at the lower end are provided with snap-fit bolts 14 at the corresponding positions of the notch 13. The distance between the end face of the snap-fit bolt 14 and the second annular grid 11 is not less than the thickness of the first grid bar 12. In the first position, the first grid bar 12 is snapped onto the stud of the snap-fit bolt 14.
[0075] In this example, the first grid bar 12 has a notch 13 on the side near the second annular grid 11. In another example, the first grid bar 12 has notches 13 on both the side near the second annular grid 11 and the lower end of the first annular grid 16.
[0076] In this disclosure, a notch 13 is provided on the first grid bar 12, and a corresponding snap-fit bolt 14 is provided at the corresponding position. This allows the first grid bar 12 to be snapped onto the stud of the snap-fit bolt 14 when in the first position, ensuring the stability of the first grid bar 12 in the first position. This further ensures the integrity and aesthetics of the protective shell and prevents the first grid bar 12 from swaying under wind force, thus ensuring the stability of the protective shell. In one example, the distance between the end face of the snap-fit bolt 14 and the second annular grid 11 is equal to the thickness of the first grid bar 12, so that the first grid bar 12 can only move to the second position under the action of external force, ensuring the stability of the protective shell. In another example, the distance between the end face of the snap-fit bolt 14 and the second annular grid 11 is slightly greater than the thickness of the first grid bar 12. This allows for quick snap-fit between the first grid bar 12 and the snap-fit bolt 14, while also ensuring that the snap-fit bolt 14 has a certain clamping force on the first grid bar 12, so that the first grid bar 12 can only be separated from the snap-fit bolt 14 under the action of a certain external force. In this example, the distance between the end face of the snap-fit bolt 14 and the second annular grid 11 is approximately 0.5mm-1.5mm different from the thickness of the first grid bar 12. For example, the distance between the end face of the snap-fit bolt 14 and the second annular grid 11 is approximately 0.5mm, 0.75mm, 1mm, 1.25mm, 1.5mm, etc., different from the thickness of the first grid bar 12.
[0077] In another example, in the first group of bars, participants Figure 2 and Figure 3 The number of first grid bars 12 can be two; the notches 13 on the two first grid bars 12 are located on the side of the two first grid bars 12 that are close to each other.
[0078] In one embodiment of this disclosure, the second grid bar 15 has a first structure 151 and a second structure 152 connected sequentially along a direction away from the base 23. The first structure 151 and the second structure 152 are not parallel to each other (the included angle between the first structure 151 and the second structure 152 is an obtuse angle). The first structure 151 is vertically arranged, and one end of the second structure 152 is connected to the first structure 151, while the other end extends toward the nozzle 20. The structure of the first grid bar 12 is the same as that of the second grid bar 15, so that the protective shell forms a structure that is wider at the top and narrower at the bottom, improving aesthetics and facilitating the installation of the protective structure. In this example, the first structure 151 is located at the lower end of the first annular grid 16 (the first annular grid 16 located at the lower end).
[0079] In one embodiment of this disclosure, a protective structure is located inside the protective shell and surrounds the nozzle 20 and the igniter structure 21. The protective structure includes a heat shield 18 and a wind shield 17. The heat shield 18 overlaps the first structure 151, creating a gap between the heat shield 18 and the support platform 29. The wind shield 17 is positioned on the side of the heat shield 18 away from the support platform 29. The wind shield 17 has multiple mesh holes with an opening ratio of 52%-57%. The position of the wind shield 17 away from the support platform 29 is lower than the second end of the igniter structure 21. In this disclosure, the mesh hole opening ratio is controlled at 52%-57%, which effectively controls the wind force, ensuring the stability of the flame-spraying performance system, while also controlling costs. For example, the mesh hole opening ratio is 52%. Another example is 54%. Yet another example is 55.6%. And yet another example is 56.4%. For another example, the opening rate of the mesh is 57%.
[0080] In this disclosure, a gap is limited between the heat shield 18 and the support platform 29. This allows the nozzle 20 to be easily removed from the side by using the gap between the heat shield 18 and the support platform 29 to lift or tilt the heat shield 18. This enables the nozzle 20 to be removed from between the heat shield 18 and the support platform 29 without removing the protective structure, saving steps and improving maintenance efficiency.
[0081] In one embodiment of this disclosure, there can be multiple first grid strip groups inside the protective shell. This way, when fixing the ignition unit 1 in the water, any one of the first grid strip groups can be aligned with the shore, making the setting position relatively flexible.
[0082] In one embodiment of this disclosure, the pressure relief structure includes a pressure relief pipe 9 and a pressure relief valve 10 disposed on the pressure relief pipe 9. The first end of the pressure relief pipe 9 is connected to each of the second sub-pipes 71, and the second end of the pressure relief pipe 9 is connected to the lower middle end of the material box 4. The diameter of the pressure relief pipe 9 is not less than the diameter of the first sub-pipe 72. In one example, the diameter of the pressure relief pipe 9 is equal to the diameter of the first sub-pipe 72, thus ensuring that all pipes have the same diameter, high versatility, and ease of replacement. In another example, the diameter of the pressure relief pipe 9 is greater than the diameter of the first sub-pipe 72, thereby improving pressure relief efficiency. In this example, the connection method between the pressure relief pipe 9 and each of the second sub-pipes 71 can be the same as the connection method between the first sub-pipe 72 and each of the second sub-pipes 71.
[0083] Optionally, the pressure relief pipe 9 is a flexible hose.
[0084] In one embodiment of this disclosure, see [link to relevant documentation]. Figure 1 and Figure 5The ignition unit 1 is located in the water. The fire-breathing performance system also includes a ladder and a mounting base 22; the mounting base 22 is located in the second area of the column 24. The ladder has a ladder body 25 and hooks 26 located at both ends of the body, one of which can be hooked onto the mounting base 22. When maintenance is required, one end of the ladder is hooked onto the mounting base 22, and the other end is placed at an angle on the ground, allowing personnel to use the ladder to move to the ignition unit 1 to replace or maintain the nozzle 20.
[0085] In this disclosure, during the performance, the first valve 8 and the second valve are activated, the pressure relief valve 10 is closed, and the pressurization pump 3 supplies fuel to the pressure booster and regulator group 2. After the pressure booster and regulator group 2 pressurizes the fuel to 4-6 MPa, it outputs high-pressure fuel and delivers it to the nozzle 20. After being atomized by the nozzle 20, the fuel is ignited by the igniter structure 21 to perform a fire-spraying performance.
[0086] In the depressurized state, close the first valve 8 and the second valve, and start the pressure relief valve 10 to depressurize the system.
