Description

Technical Field

[0001] This utility model relates to fire drill equipment, specifically to a combustion bed used for fire drills. Background Technology

[0002] In fire training, a combustion bed is an important device for simulating bed combustion and fire. It mainly consists of components such as gas supply pipes, control valve groups, ignition devices, and combustion devices. In order to achieve the ability to handle fires of different sizes, the combustion area and flame height of the combustion bed should have certain variations.

[0003] Existing combustion beds have the following drawbacks: First, the high temperature generated by the combustion flame affects the lifespan of the equipment; second, the controllability of the combustion area is not high; and third, the height of the combustion flame cannot be adjusted. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a combustion bed that is less affected by high temperature, has a long service life, and has an adjustable combustion area and flame.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A combustion bed for fire drills includes a simulated bed body, a combustion device, an ignition device and a temperature sensing device. A water bath is provided in the central area of ​​the simulated bed body. The combustion device is immersed in the water in the water bath. The ignition device is fixed to the simulated bed body and adjacent to the combustion device, so that the ignition device ignites the combustion device above the water surface. The temperature sensing device is located above the water bath for temperature measurement.

[0006] The beneficial effects of this utility model are: by setting a water bath tank on the simulated bed, the combustion device is immersed in the water bath tank to form a water bath combustion, which can control the combustion area, reduce the ambient temperature, and extend the service life.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, the combustion device includes a main combustion assembly, which includes at least two combustion tubes. Combustible gas flows inside each combustion tube, and the tube wall of each combustion tube is provided with an exhaust port for discharging the combustible gas. The combustion tubes in the main combustion assembly are ignited individually or in combination.

[0009] The beneficial effects of adopting the above-mentioned further solution are that the combustible gas is discharged from the exhaust port and ignited above the water surface, so that the combustion area is located on the water surface of the water bath, avoiding the impact of high flame temperature on service life, and multiple combustion tubes can be used individually or in combination, which can fully adjust the flame.

[0010] Furthermore, the combustion device also includes a sub-combustion assembly, which forms a constant flame after being ignited.

[0011] The beneficial effect of adopting the above-mentioned further scheme is that the sub-combustion assembly can be combined with the main combustion assembly to form different simulated fire conditions, increasing the variety of simulated fire conditions in the combustion bed.

[0012] Furthermore, the main combustion assembly includes an inner combustion pipe and an outer combustion pipe. The outer combustion pipe is arranged around the inner side of the water bath tank and is located outside the inner combustion pipe, with a gap between the inner combustion pipe and the outer combustion pipe.

[0013] The beneficial effect of adopting the above-mentioned further scheme is that by using internal and external combustion tubes, it is possible to select and ignite either of the combustion tubes, thereby achieving adjustment of the combustion area.

[0014] Furthermore, the distances from the inner combustion pipe and the outer combustion pipe to the bottom of the water bath are equal.

[0015] The beneficial effect of adopting the above-mentioned further scheme is that the inner and outer combustion tubes are located on the same plane, which is conducive to controlling the depth of the combustion tubes immersed in water and controlling the combustion range.

[0016] Furthermore, the sub-combustion assembly is surrounded by the inner combustion tube, and the sub-combustion assembly shares an ignition device with the main combustion assembly.

[0017] The advantage of adopting the above-mentioned further solution is that the sub-combustion assembly is conveniently located to share the ignition device with the main combustion assembly, thereby reducing the number of ignition devices and thus lowering costs.

[0018] Furthermore, the temperature sensing device corresponds to the interval between the inner combustion tube and the outer combustion tube.

[0019] The beneficial effect of adopting the above-mentioned further solution is that the temperature sensing device can accurately obtain the temperature of the combustion environment, which is beneficial to adjust the combustion area of ​​the combustion bed according to the temperature.

[0020] Furthermore, the bottom of the water bath is provided with a sealable drain outlet.

[0021] The beneficial effect of adopting the above-mentioned further solution is that wastewater from the water bath can be discharged through the drain outlet, and it has the advantages of simple structure and convenient operation.

[0022] Furthermore, a grating plate is included, which is detachably covered on the water bath, and a temperature sensing device is fixed to the grating plate.

[0023] The beneficial effect of adopting the above-mentioned further solution is that the grating plate covers the water bath, which can not only ensure the smooth progress of the simulation training, but also prevent debris from falling into the water bath. At the same time, the grating plate can provide an installation position for the temperature sensing device.

[0024] Furthermore, the ignition device includes an ignition needle and a bracket, with the ignition needle fixed in the water bath by the bracket.

[0025] The advantage of adopting the above-mentioned further solution is that the ignition device is simple in structure and easy to fix. Attached Figure Description

[0026] Figure 1 This is a schematic diagram of the structure of a combustion bed for fire drills according to the present invention; Figure 2 This is a side view of a combustion bed used for fire drills according to the present invention.

[0027] The attached diagram lists the components represented by each number as follows: 1. Simulated bed; 2. Water bath; 3. External combustion pipe; 4. Internal combustion pipe; 5. Sub-combustion assembly; 6. Ignition needle; 7. Connector; 8. Drain outlet; 9. Temperature sensing device. Detailed Implementation

[0028] 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.

[0029] Example 1 This embodiment provides a combustion bed for fire drills, including a simulated bed body 1, a combustion device, an ignition device, and a temperature sensing device 8. The central area of ​​the simulated bed body 1 is provided with a water bath 2. The combustion device is immersed in the water in the water bath 2. The ignition device is fixed to the simulated bed body 1 and adjacent to the combustion device, so that the ignition device ignites the combustion device above the water surface. The temperature sensing device 8 is located above the water bath 2 for temperature measurement.

[0030] In this embodiment, by setting a water bath 2 on the simulated bed 1, the combustion device is immersed in the water bath 2 to form a water bath combustion, which can control the combustion area, reduce the ambient temperature, and extend the service life.

[0031] Specifically, such as Figure 1 and 2As shown, the bed board of the simulated bed 1 has a certain thickness. A water bath 2 of a certain depth is provided in the central area of ​​the bed board. The combustion device is fixedly installed in the water bath 2. Preferably, the combustion device is fixed to the bottom of the water bath 2. At least one end of the combustion device is located outside the water bath 2 to receive combustible gas. The part outside the water bath 2 is provided with a gas supply pipe. The gas supply pipe is provided with a control valve group, which can control the flow rate of combustible gas in the gas supply pipe. Combustible gas flows inside the combustion device located in the water bath 2. The combustion device is equipped with a valve for discharging combustible gas. When clean water is poured into the water bath 2, the combustion device is immersed in the water. Preferably, the height of the exhaust port is higher than the water surface, which facilitates the flow of combustible gas and prevents water from entering the combustion tube and affecting the flow of combustible gas. The ignition device is fixed on the simulation bed 1 and adjacent to the combustion device. In this embodiment, the ignition device is located above the combustion device and is used to ignite the combustible gas overflowing from the water surface of the combustion device, thereby forming a water bath combustion, which can effectively control the combustion temperature and extend the service life. The temperature sensing device 8 is located above the water bath 2 for temperature measurement.

[0032] In this embodiment, the number of ignition devices, combustion devices and temperature sensing devices 8 is not specifically limited. Without considering cost, it is preferable that there are multiple ignition devices, combustion devices and temperature sensing devices 8. The ignition devices can correspond one-to-one with the combustion devices, or multiple combustion devices can share one ignition device. The multiple temperature sensing devices 8 are preferably distributed to facilitate precise temperature control and easy adjustment.

[0033] Example 2 Based on Embodiment 1, the combustion device includes a main combustion assembly, which includes at least two combustion tubes. Combustible gas flows inside each combustion tube, and the tube wall of each combustion tube is provided with an exhaust port for discharging the combustible gas. The combustion tubes in the main combustion assembly are ignited individually or in combination.

[0034] In this embodiment, combustible gas is discharged from the exhaust port and ignited above the water surface, so that the combustion area is located on the water surface of the water bath 2, avoiding the impact of high flame temperature on service life. Multiple combustion tubes can be used individually or in combination, and the flame can be fully adjusted.

[0035] Specifically, the combustion tube is fixed in the water bath 2. Multiple exhaust holes are opened on the tube wall of the combustion tube. The distance between two adjacent exhaust holes and the diameter of each exhaust hole can affect the amount of combustible gas discharged, thereby adjusting the combustion area. In other words, different combustion areas can be obtained by replacing combustion tubes of different specifications. The number, diameter, and spacing of exhaust holes of multiple combustion tubes, as well as the arrangement of two adjacent combustion tubes, can also affect the combustion area.

[0036] In this embodiment, it is preferable that multiple combustion tubes are provided in the water bath 2. The combustion area can be adjusted by igniting one of the combustion tubes individually, or by igniting any two or more combustion tubes in combination.

[0037] Example 3 Based on Embodiment 2, the combustion device further includes a sub-combustion assembly 5, which, when ignited, forms a constant flame. In this embodiment, the sub-combustion assembly 5 can combine with the main combustion assembly to form different fire conditions, increasing the variety of simulated fire conditions on the combustion bed.

[0038] Specifically, such as Figure 1 As shown, only one sub-combustion component 5 is set in the water bath tank 2. The sub-combustion component 5 is set in advance according to actual needs before the fire drill. In this embodiment, the sub-combustion component 5 is a small burner that can output combustible gas evenly. When the sub-combustion component 5 is ignited, it can form a constant open flame.

[0039] In other embodiments, multiple sub-combustion components 5 can be set, and the position of each sub-combustion component 5 can be placed arbitrarily. However, since the constant open flame formed by the sub-combustion components 5 is relatively fixed in terms of combustion area and installation position, it is not advisable to place too many.

[0040] Example 4 Based on the above embodiments, the main combustion assembly includes an inner combustion tube 4 and an outer combustion tube 3. The outer combustion tube 3 is arranged around the inner side of the water bath 2, surrounding the outer side of the inner combustion tube 4, with a gap between the inner combustion tube 4 and the outer combustion tube 3. In this embodiment, the use of inner and outer combustion tubes 3 allows for the selection of either combustion tube to be ignited, thereby adjusting the combustion area.

[0041] Specifically, such as Figure 1 As shown, the main combustion assembly includes an inner combustion pipe 4 and an outer combustion pipe 3. The outer combustion pipe 3 is arranged around the inner sidewall of the water bath 2 outside the inner combustion pipe 4, and a certain gap is left between the outer combustion pipe 3 and the inner sidewall of the water bath 2. Preferably, the inner combustion pipe 4 and the outer combustion pipe 3 have the same shape but different sizes. Figure 1 In this embodiment, both the inner combustion pipe 4 and the outer combustion pipe 3 adopt a U-shaped structure, which has the advantages of simple structure and wide coverage. In this embodiment, both the inner combustion pipe 4 and the outer combustion pipe 3 extend out of the water bath 2 from the same side wall of the water bath 2, which facilitates the introduction of combustible gas from the same direction. That is, the open end of the U-shaped structure extends out from one end of the water bath 2, and the closed end of the U-shaped structure is located in the water bath 2.

[0042] Of course, a U-shaped combustion tube can be installed in the gap between the inner combustion tube 4 and the outer combustion tube 3, but adding a combustion tube will inevitably increase the cost of the device.

[0043] Example 5 Based on the above embodiment, the distances from the inner combustion pipe 4 and the outer combustion pipe 3 to the bottom of the water bath 2 are equal. In this embodiment, the inner and outer combustion pipes 3 are located on the same plane, which facilitates control of the depth of the combustion pipes immersed in water and control of the combustion range.

[0044] Specifically, in this embodiment, the distances from the inner combustion pipe 4 and the outer combustion pipe 3 to the bottom of the water bath tank 2 are equal, so that the distances from the exhaust holes of the inner combustion pipe 4 and the outer combustion pipe 3 to the bottom of the water bath tank 2 are also equal. As a result, the exhaust holes of all combustion pipes are at the same height above the water surface, so that the combustion heights of the inner combustion pipe 4 and the outer combustion pipe 3 are equal, which makes it easier to control the depth of the combustion pipes immersed in the water.

[0045] Example 6 Based on the above embodiment, the sub-combustion assembly 5 is surrounded by the inner combustion tube 4, and the sub-combustion assembly 5 shares an ignition device with the main combustion assembly. In this embodiment, the sub-combustion assembly 5 is positioned to facilitate sharing an ignition device with the main combustion assembly, thereby reducing the number of ignition devices and lowering costs.

[0046] Specifically, such as Figure 1 As shown, the inner combustion tube 4 forms a U-shaped structure, and the sub-combustion assembly 5 is disposed within the space enclosed by the inner combustion tube 4, with the sub-combustion assembly 5 being closer to the closed end of the inner combustion tube 4. In this embodiment, there are two ignition devices, each disposed between the inner combustion tube 4 and the outer combustion tube 3. One ignition device is used to ignite the inner combustion tube 4 and the sub-combustion assembly 5, and the other ignition device is used to ignite the outer combustion tube 3.

[0047] Example 7 Based on the above embodiment, the temperature sensing device 8 is located in the gap between the inner combustion tube 4 and the outer combustion tube 3. In this embodiment, the temperature sensing device 8 can accurately obtain the temperature of the combustion environment, which is beneficial for adjusting the combustion area of ​​the combustion bed according to the temperature.

[0048] Specifically, such as Figure 1 As shown, there are two temperature sensing devices 8, each fixed above the water bath 2, and each temperature sensing device 8 corresponds to the gap between the inner combustion pipe 4 and the outer combustion pipe 3. One temperature sensing device 8 is closer to the closed end of the outer combustion pipe 3, and the other temperature sensing device 8 is closer to the open end of the outer combustion pipe 3. In this embodiment, the temperature sensing device 8 is a temperature sensor.

[0049] Example 8 Based on the above embodiments, the bottom of the water bath tank 2 is provided with a sealable drain outlet 7, so that wastewater from the water bath tank 2 can be discharged through the drain outlet 7, which has the advantages of simple structure and convenient operation.

[0050] Specifically, such as Figure 1 , 2 As shown, a drain outlet 7 is provided at the bottom of the water bath tank 2. The drain outlet 7 can be easily opened or closed by a valve, faucet or other device, so that sewage can be discharged from the drain outlet 7.

[0051] Example 9 Based on the above embodiment, the combustion bed is also covered with a grating plate, which is detachably sealed onto the water bath 2, and the temperature sensing device 8 is fixed to the grating plate. In this embodiment, the grating plate seals the water bath 2, which not only ensures the smooth progress of the simulation training but also prevents debris from falling into the water bath 2. At the same time, the grating plate provides an installation position for the temperature sensing device 8.

[0052] Specifically, in this embodiment, the grating plate is a plate with mesh-shaped through holes. When the grating plate is covered on the water bath tank 2, the upper surface of the grating plate is flush with the surface of the simulated bed 1, which can ensure the surface flatness of the combustion bed and also prevent debris from falling into the water bath tank 2.

[0053] Preferably, the grating plate is detachably covered on the water bath 2. When the combustion device is ignited, the flame can pass through the through holes of the grating plate. The detachable connection between the grating plate and the water bath 2 includes, but is not limited to, a detachable connection formed by screws and nuts, and a detachable connection formed by buckles and slots.

[0054] In this embodiment, the grille also provides an installation location for the temperature sensing device 8. Figure 2 In the middle, the temperature sensing device 8 is fixed to the upper surface of the grid plate.

[0055] Example 10 Based on the above embodiments, the ignition device includes an ignition needle 6 and a bracket, wherein the ignition needle 6 is fixed in the water bath 2 by the bracket. In this embodiment, the ignition device has a simple structure and is easy to fix.

[0056] like Figure 1 As shown, the ignition device includes a bracket and an ignition needle 6. The bracket is supported on the bottom of the water bath 2, and the ignition needle 6 is fixed to the bracket, so that the height of the ignition needle 6 is higher than the water surface of the water bath 2. In this embodiment, the ignition needle 6 can pass through the gaps in the grille plate, so that the ignition needle 6 and the temperature sensing device 8 are as follows: Figure 2 As shown, they are located on the side of the grating plate opposite to the water bath 2. Preferably, a waterproof connector 61 is provided at the bottom of the water bath 2. The waterproof connector 61 is used to connect the control line and power line of the ignition needle 6.
