Description

Technical Field

[0001] The utility model relates to the technical field of fire smoke exhaust, in particular to a fire smoke exhaust device. Background Art

[0002] According to research, when a fire occurs, the number of people who die due to thick smoke is 4 to 5 times the number of people who die from burns. The fundamental reason is that on the one hand, thick smoke blocks the field of vision, making it difficult for trapped people to see the escape route, and on the other hand, the toxic gases in the thick smoke can easily cause trapped people to become poisoned and lose consciousness. Therefore, when a fire occurs, rapid smoke exhaust is one of the best ways to rescue trapped people. Therefore, a smoke exhauster is needed to quickly exhaust the thick smoke so that people can be rescued quickly.

[0003] The utility model with the publication number CN218410201U proposes a fast smoke exhaust machine, including a transport base, universal wheels are movably installed at the four corners of the bottom side of the transport base, and a smoke exhaust box is installed on the other side of the transport base; a detachable smoke inlet pipe is installed in the middle of one side of the smoke exhaust box, and an exhaust fan is detachably installed on one side of the inside of the smoke inlet pipe; a smoke exhaust pipe is detachably installed on the top of the other side of the smoke exhaust box, and an exhaust fan is detachably installed on one side of the inside of the smoke exhaust pipe. The technical solution of this application can not only draw the smoke into the smoke exhaust box and discharge it from the smoke exhaust pipe through the transport base, smoke exhaust box, smoke inlet pipe, exhaust fan, smoke exhaust pipe, exhaust fan, cover, spray plate and connecting pipe, but also when the smoke enters the smoke exhaust box, the two groups of spray plates on the cover will reduce dust and cool the discharged smoke, ensuring that the discharged smoke not only reduces the pollution to the environment, but also reduces the temperature of the discharged smoke to avoid scalding pedestrians.

[0004] However, the above-mentioned prior art still has the following deficiencies when used: 1. The temperature of the thick smoke is relatively high, and the flow rate through the smoke exhaust box is relatively fast. The spray cooling function in the smoke exhaust box cannot effectively cool and filter the thick smoke flowing through, and the spray water is easily vaporized and combined with harmful dust in the smoke, and then discharged to the outside along with the smoke, resulting in the exhaust gas not only having a high temperature but also having certain pollution, and there is a defect of poor cooling and environmental protection treatment effect; 2. When in use, the transport base is pushed to the designated location, the smoke inlet pipe is placed at the thick smoke position, and then the smoke is discharged outward. Since the thick smoke is usually gathered and the position is not fixed, the above-mentioned smoke inlet pipe has the defect of inconvenient position adjustment and the defect of not extending into the smoke gathering area.

[0005] To this end, the utility model provides a fire-fighting smoke exhaust device. Utility Model Content

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] See also Figures 1 to 3 The utility model provides a technical solution: a fire smoke exhaust device, including a transport base 1, a spray box 2 is arranged on the top of the transport base 1, and the transport base 1 and the spray box 2 both adopt the structure in the patent document mentioned in the background technology, and this technical solution will not be described in detail.

[0024] Among them, an exhaust duct 3 is arranged on one side of the spray box 2 and an exhaust duct 4 is arranged on the other side thereof. The exhaust duct 3 has an exhaust fan built in, and the exhaust duct 4 has an exhaust fan built in. When in use, when the exhaust duct 3 and the exhaust duct 4 are in operation, smoke enters through the exhaust duct 3, is sprayed by the spray box 2, and is discharged from the exhaust duct 4. The spray box 2 sprays, cools down, and purifies the smoke passing through.

[0025] In the present technical solution, a spiral tube 5 with a vertical spiral axis is connected in series to the exhaust pipe 3, that is, after the smoke enters the exhaust pipe 3, it will flow through the spiral tube 5, extending the distance the smoke flows through. The free end of the exhaust pipe 3 is rotatably connected to a switching sleeve 6. The switching sleeve 6 and the exhaust pipe 3 are coaxially arranged, and a bearing can be arranged between the two. The outer periphery of the switching sleeve 6 is fixedly connected to a smoke inlet pipe 7, and the smoke inlet pipe 7 can be perpendicular to the switching sleeve 6 and can be inclined relative to the axis of the switching sleeve 6. The function of the smoke inlet pipe 7 is to guide the smoke. The rotating arrangement of the switching sleeve 6 makes it convenient to align the smoke inlet pipe 7 with the gathered thick smoke, thereby improving the smoke exhaust efficiency.

[0026] Among them, a cooling fan 103 is arranged on the transport base 1 and is located below the spiral tube 5. When the cooling fan 103 is started, air will be blown to the spiral tube 5, which can accelerate the cooling of the smoke passing through the spiral tube 5. After the cooled smoke enters the spray box 2, the water sprayed from the spray disk in the spray box 2 will further cool the low-temperature smoke, and at the same time filter out the dust in the smoke, and can greatly reduce the amount of water vapor formed, thereby improving the environmental protection effect.

[0027] In this embodiment, a support leg 11 is welded to the top of the transport base 1, and the support leg 11 is fixedly connected to the bottom of the spray box 2. The exhaust pipe 3 and the spiral tube 5 form a Z shape, and the height of the adapter sleeve 6 is lower than the height of the connection between the exhaust pipe 3 and the spray box 2. This arrangement can lower the reference height of the adapter sleeve 6, making it easier to connect with the smoke outlet position or channel.

[0028] A control assembly 9 for controlling the rotation of the adapter sleeve 6 is also provided on the transport base 1.

[0029] Specifically, the control assembly 9 includes a transmission shaft 91, a transmission gear 92 and a passive gear 93. The transmission shaft 91 is rotatably connected to the top of the transport base 1, and one end of the transmission shaft 91 is fixedly connected to the transmission gear 92. The passive gear 93 is fixedly sleeved on the adapter sleeve 6 and meshes with the transmission gear 92. The transmission shaft 91 passes under the spray box 2, and a handle can be welded on the outer peripheral wall of the transmission shaft 91. The rotation of the transmission shaft 91 can be controlled manually through the handle, and the position of the entrance of the smoke inlet pipe 7 can be adjusted through the meshing cooperation of the transmission gear 92 and the passive gear 93.

[0030] In this embodiment, the control combination 9 includes a control motor 94, which is fixedly arranged on the top of the transport base 1 and has its output shaft fixedly connected to one end of the transmission shaft 91. That is to say, the transmission shaft 91 can be controlled to rotate by the control motor 94 without the need for human operation, thereby reducing labor intensity.

[0031] In this embodiment, the free end of the smoke inlet pipe 7 is fixedly connected to a smoke guide pipe 8 parallel to the exhaust pipe 3. The outer wall of the smoke guide pipe 8 is provided with evenly distributed smoke inlet holes 81. This arrangement can increase the range of thick smoke absorption and thus increase the field of view.

[0032] In this embodiment, the free end of the exhaust duct 4 is fixedly connected with a short pipe 101 with an opening facing upward, and an extension pipe 102 is plugged into the short pipe 101, that is, the extension pipe 102 is detachable. The function of the extension pipe 102 is to discharge the smoke exhausted from the exhaust duct 4 to a higher place after being plugged into the short pipe 101, so as to avoid the exhausted smoke affecting the field of vision.

[0033] Furthermore, a pipe rack 12 close to one side and used to place the extension tube 102 is fixedly connected to the top of the transport base 1. The pipe rack 12 can be a U-shaped frame structure, which is used to hold up the unused extension tube 102, thereby improving the convenience of carrying the extension tube 102.

[0034] Working principle: When a fire occurs indoors or in a building and thick smoke is formed, the transport base 1 is pushed to make the smoke guide pipe 8 enter the position where the thick smoke gathers, and then the transmission shaft 91 is controlled to rotate to adjust the position of the smoke guide pipe 8, so that the smoke guide pipe 8 enters the thick smoke, and then the spray box 2, the exhaust pipe 3, the exhaust pipe 4 and the cooling fan 103 are started. The thick smoke enters through the smoke inlet hole 81, and then enters the spiral tube 5. After cooling and heat dissipation by the spiral tube 5, it enters the spray box 2. The thick smoke is further cooled and purified after being sprayed, and the processed smoke is discharged outward through the exhaust pipe 4, thereby realizing the thick smoke discharge and purification function.

[0035] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
