Description

Technical Field

[0001] This utility model relates to a fire drill device, specifically a device for simulating fire in door gaps during fire drills. Background Technology

[0002] In fire drills, simulating fires through door gaps is of great significance for firefighters entering and extinguishing indoor fires. Currently, the simulation of fires through door gaps typically involves installing a combustion device at the door and door frame to simulate an indoor fire. This combustion device mainly consists of a gas supply pipe, control valve assembly, ignition device, and combustion unit. However, existing simulation devices for fires through door gaps have limitations: the flame position is fixed and singular; in particular, the flame size does not change with the degree of door opening or closing, failing to replicate the backfire phenomenon that occurs when a door is opened in a real fire, thus failing to simulate the effects of a real fire and hindering firefighters' simulation training. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a combustion device that can simulate an indoor fire and create a realistic fire scene effect at the door seam.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A combustion device for simulating fire in door gaps during fire drills includes an ignition device and a combustion device. The ignition device and the combustion device are fixed together on the door frame. The ignition device is used to ignite the combustion device when the door is opened. The combustion device is equipped with a control valve group, which is used to adjust the flow rate of combustible gas in the combustion device. It also includes a door limiting device, which is located on the rotation trajectory of the door and is used by the door and the door limiting device to increase the flow rate of combustible gas.

[0005] The beneficial effects of this utility model are: when the door is opened to a certain extent, the door limiting device is triggered, and the flame of the combustion device is increased by increasing the flow of combustible gas, which can simulate the effect of the flame suddenly increasing when the door is opened in a fire, effectively ensuring the simulation training of firefighters.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, the combustion device is fixed on the horizontal and / or vertical frames of the door frame.

[0008] The advantage of adopting the above-mentioned further solution is that the combustion device can be selectively installed on the horizontal and vertical frames of the door frame, which can meet different simulation scenarios.

[0009] Furthermore, the combustion device is fixed on both the horizontal frame of the door frame and the vertical frame adjacent to the door opening side, and the length of the combustion device fixed on the horizontal frame is less than the horizontal length of the door frame.

[0010] The advantage of adopting the above-mentioned further solution is that shortening the combustion device on the horizontal frame and setting the combustion device only on the vertical frame adjacent to the door opening side, so that the combustion device corresponds to the effective area of ​​the door opening, can reduce the overall cost.

[0011] Furthermore, the combustion device fixed to the horizontal frame or the vertical frame is ignited, or the combustion devices fixed to both the horizontal frame and the vertical frame are ignited.

[0012] The advantage of adopting the above-mentioned further solution is that the selective ignition combustion device can achieve both adjustable flame and cost control.

[0013] Furthermore, the combustion device includes a combustion tube, in which combustible gas flows, and the tube wall is provided with an exhaust port for discharging the combustible gas.

[0014] The beneficial effect of adopting the above-mentioned further solution is that the combustion device is a combustion tube with exhaust holes, and the arrangement, number and diameter of the exhaust holes can also determine the flame height to a certain extent.

[0015] Furthermore, the gas supply pipe of the combustion tube extends laterally outside the door frame, and the gas supply pipe of the combustion tube is far from the ground.

[0016] The advantage of adopting the above-mentioned further solution is that the gas supply pipe of the combustion tube is located far away from the door frame, avoiding the gas supply pipe being affected by the flame and causing safety hazards.

[0017] Furthermore, the control valve assembly is disposed on the gas supply pipe of the combustion tube, and the control valve assembly includes a ball valve, a solenoid valve and an electric regulating valve arranged in sequence along the transverse direction. The ball valve is located away from the combustion tube, and the electric regulating valve is located close to the combustion tube.

[0018] The beneficial effect of adopting the above-mentioned further scheme is that the flow rate of combustible gas in the combustion tube can be controlled by the control valve group, which can quickly and effectively achieve the control of combustible gas flow rate.

[0019] Furthermore, the ignition device is located on the side of the combustion device facing away from the door. On the horizontal frame, the ignition device corresponds to the middle of the adjacent combustion device, and on the vertical frame, the ignition device corresponds to the upper end of the adjacent combustion device.

[0020] The beneficial effect of adopting the above-mentioned further solution is that the ignition device is set on the side of the combustion device facing away from the door, which can both avoid the ignition device affecting the flame adjustment of the combustion device and avoid the flame affecting the performance of the ignition device.

[0021] Furthermore, the door limiting device is fixed to the ground, and the bottom of the door cooperates with the door limiting device.

[0022] The beneficial effect of adopting the above-mentioned further solution is that the fixed position of the door limit device not only ensures precise matching with the door limit, but also saves space and reduces interference with simulation training.

[0023] Furthermore, the door limiting device is a switching element.

[0024] The advantage of adopting the above-mentioned further solutions is that using switching elements helps to reduce costs. Attached Figure Description

[0027] The principles and features of this utility model are described below. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0028] Example 1 This embodiment provides a combustion device for simulating a fire in a door gap during a fire drill, including an ignition device 4 and a combustion device 3. The ignition device 4 and the combustion device 3 are fixed together on the door frame. The ignition device 4 is used to ignite the combustion device 3 when the door 1 is opened. The combustion device 3 is equipped with a control valve group 5, which is used to adjust the flow rate of combustible gas in the combustion device 3. It also includes a door limiting device 6, which is located on the rotation trajectory of the door 1. The door 1 and the door limiting device 6 cooperate to increase the flow rate of combustible gas. That is, when the door 1 triggers the door limiting device 6, the control valve group 5 increases the flow rate of combustible gas.

[0029] The beneficial effects of this utility model are: when the door 1 is opened to a certain extent, the door limiting device 6 is triggered, and by increasing the flow of combustible gas, the flame of the combustion device 3 is increased, which can simulate the effect of the flame suddenly increasing when the door 1 is opened in the fire scene, effectively ensuring the simulation training of firefighters.

[0030] Specifically, such as Figure 1 As shown, the combustion device simulating a fire in a door gap during a fire drill is used in conjunction with the door frame and door 1. In this embodiment, door 1 is rotatably installed on the door frame. The ignition device 4, control valve group 5, and door limit device 6 in the combustion device simulating a fire in a door gap during a fire drill are all connected to the same control unit. The device is automated through signal transmission. For example, the control unit is a microcontroller. The control unit outputs a control signal to control ignition. After receiving the control signal, the ignition device 4 performs the ignition action. The control unit outputs an open or close control signal to the control valve group 5. After receiving the signal, the control valve group 5 performs the open or close action. When the control valve group 5 is in the open state, the control unit can output a control signal to the control valve group 5 to adjust the opening size of the control valve group 5, thereby realizing the control of the combustible gas flow.

[0031] Preferably, a door limit device 6 is also provided. The door limit device 6 is installed on the rotation trajectory of the door 1. After being triggered by the door 1, the door limit device 6 can feed back a signal to the control unit via wired or wireless means. When the control unit receives the signal fed back by the door limit device 6, the control unit outputs a control signal to adjust the opening size of the control valve group 5. In this embodiment, after receiving the feedback signal from the door limit device 6, the control unit controls the opening range of the control valve group 5 to be increased to increase the amount of combustible gas flowing into the combustion device 3.

[0032] The method of use is as follows: When door 1 is closed, control valve group 5 is closed, there is no combustible gas in combustion device 3, and ignition device 4 is not activated; when door 1 is pushed open, control valve group 5 is opened, combustible gas flows into combustion device 3, ignition device 4 is activated, combustion device 3 is ignited, and an initial door gap fire is formed between door frame and door 1; then door 1 continues to be opened, and when door 1 triggers limit device 6, after the control unit receives feedback signal, control valve group 5 is driven to increase the flow rate. Due to the sudden increase in combustible gas flowing into combustion device 3, the flame suddenly increases and forms the largest door gap fire, thereby simulating the instantaneous increase of fire at the door gap.

[0033] In another embodiment, the ignition action of the ignition device 4 and the opening and closing of the control valve group 5 can be manually controlled.

[0034] Example 2 Based on the above embodiment, the combustion device 3 is fixed on the horizontal frame 21 and / or the vertical frame 22 of the door frame. In this embodiment, the combustion device 3 can be selectively installed on the horizontal frame 21 and the vertical frame 22 of the door frame to meet different simulation scenarios.

[0035] like Figure 1 As shown, the door frame includes two longitudinal frames 22 spaced apart, and a transverse frame 21 connected to the end of the two longitudinal frames 22 away from the ground. The combustion device 3 can be arbitrarily selected from the two longitudinal frames 22 and the transverse frame 21, and two or three can be installed, thereby facilitating the simulation of different simulation scenarios. Specifically, when the combustion device 3 is set in the transverse frame 21, it can form a door gap fire in the gap between the door 1 and the transverse frame 21. When the combustion device 3 is set in the longitudinal frame 22, it can form a door gap fire in the gap between the door 1 and the longitudinal frame 22 on the side closer to the push door 1, or it can form a door gap fire in the gap between the door 1 and the longitudinal frame 22 on the side away from the push door 1.

[0036] Example 3 Based on the above embodiment, the combustion device 3 is fixed on both the horizontal frame 21 of the door frame and the vertical frame 22 adjacent to the door opening side, and the length of the combustion device 3 fixed on the horizontal frame 21 is less than the horizontal length of the door frame.

[0037] In this embodiment, by shortening the combustion device 3 on the horizontal frame 21 and setting the combustion device 3 only on the vertical frame 22 adjacent to the door 1, the combustion device 3 corresponds to the effective area of ​​the door 1, thereby reducing the overall cost.

[0038] Example 4 Based on the above embodiments, the combustion device 3 fixed to the horizontal frame 21 or the vertical frame 22 is ignited, or both the combustion devices 3 fixed to the horizontal frame 21 and the vertical frame 22 are ignited. In this embodiment, selective ignition of the combustion device 3 achieves both adjustable flame and cost control.

[0039] Example 5 Based on the above embodiments, the combustion device 3 includes a combustion tube through which combustible gas flows, and the tube wall is provided with exhaust holes for discharging the combustible gas. In this embodiment, the combustion device 3 is a combustion tube with exhaust holes, and the arrangement, number, and diameter of the exhaust holes can, to a certain extent, determine the flame height.

[0040] Specifically, in this embodiment, an ignition device 4 is installed on the side of the combustion tube facing away from the door 1. The combustion tube is a straight tube, with one combustion tube fixed horizontally to the horizontal frame 21 and the other combustion tube fixed vertically to the vertical frame 22. Figure 1In the middle, the right end of the combustion tube located on the horizontal frame 21 is adjacent to the upper end of the combustion tube located on the vertical frame 22 and is used to connect with their respective gas supply pipes 31, so as to facilitate the layout of the gas supply pipes 31.

[0041] Example 6 Based on the above embodiment, the gas supply pipe 31 of the combustion pipe extends laterally outside the door frame, and the gas supply pipe 31 of the combustion pipe is far away from the ground.

[0042] In this embodiment, the gas supply pipe 31 of the combustion tube is located far away from the door frame to avoid the gas supply pipe 31 being affected by the flame and causing safety hazards.

[0043] Specifically, such as Figure 1 As shown, the right end of the combustion pipe located on the horizontal frame 21 is connected to the gas supply pipe 31, which extends horizontally away from the horizontal frame 21. The upper end of the combustion pipe located on the vertical frame 22 is connected to the gas supply pipe 31, which also extends horizontally away from the vertical frame 22. At this time, the gas supply pipes 31 of the two combustion pipes extend parallel in the area away from the ground to avoid interference.

[0044] Example 7 Based on the above embodiment, the control valve assembly 5 is disposed on the gas supply pipe 31 of the combustion tube. The control valve assembly 5 includes a ball valve 51, a solenoid valve 52, and an electric regulating valve 53 arranged laterally in sequence. The ball valve 51 is located away from the combustion tube, and the electric regulating valve 53 is located close to the combustion tube. In this embodiment, the flow rate of combustible gas in the combustion tube is controlled by the control valve assembly 5, which can quickly and effectively achieve control of the combustible gas flow rate.

[0045] In this embodiment, the opening, closing, and adjustment of the control valve group 5 are all controlled by the control unit, thereby achieving automatic control and simplifying operation.

[0046] Example 8 Based on the above embodiments, the ignition device 4 is disposed on the side of the combustion device 3 facing away from the door 1. On the horizontal frame 21, the ignition device 4 corresponds to the middle of the adjacent combustion device 3, and on the vertical frame 22, the ignition device 4 corresponds to the upper end of the adjacent combustion device 3.

[0047] like Figure 1 As shown, the ignition device 4 is located on the side of the combustion device 3 facing away from the door 1, which can both prevent the ignition device 4 from affecting the flame adjustment of the combustion device 3 and prevent the flame from affecting the performance of the ignition device 4.

[0048] Example 9 Based on the above embodiment, the door limiting device 6 is fixed to the ground, and the bottom of the door 1 cooperates with the door limiting device 6. In this embodiment, the fixed position of the door limiting device 6 not only ensures precise limiting cooperation with the door 1, but also saves space and reduces interference with simulation training.

[0049] Furthermore, the door limiting device 6 is fixed to the ground and has a certain height. When the bottom of the door 1 is engaged with the door limiting device 6, it can prevent the door 1 from being pushed further, thereby limiting the opening angle of the door 1.

[0050] Example 10 Based on the above embodiments, the door limiting device 6 is a switching element. In this embodiment, using a switching element helps to reduce costs.

[0051] In this embodiment, the door limit device 6 is a switching element connected to an on / off circuit in the control unit. The on / off state of the on / off circuit can provide feedback signals to the control unit.
