Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of vehicle-mounted oil engine smoke exhaust, and particularly relates to a vehicle-mounted oil engine smoke exhaust structure with switchable smoke exhaust modes. BACKGROUND
[0002] Currently, the main smoke exhaust mode of a vehicle-mounted oil engine is to extend the oil engine smoke exhaust pipe to exhaust the smoke generated by oil engine fuel below the shelter vehicle chassis or outside the shelter roof. Both of these two smoke exhaust modes have obvious shortcomings. The smoke exhausted to the lower part of the chassis is prone to accumulate at the lower part of the chassis in a windless environment, and due to the high temperature of the smoke, it will drift upwards along the shelter and partially enter the shelter, causing the air in the shelter to be polluted and affecting the man-machine engineering experience of personnel. The smoke exhausted to the outside of the shelter roof is prone to cause the shelter vehicle to be detected by infrared detection, thus exposing the target and reducing the concealment and safety. SUMMARY

[0018] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] like Figure 1 , Figure 2 As shown, a vehicle-mounted generator exhaust structure with switchable exhaust modes includes a generator exhaust port, an exhaust pipe, a three-way connector 1, a sealing component, a rain cover 2, a deflector plate 3, a heat insulation component, and a fixing component.
[0022] In practical applications, the exhaust pipes include a lower exhaust pipe 5 and an upper exhaust pipe 4. A three-way connector 1 connects to the engine exhaust port, the upper exhaust pipe 4, and the lower exhaust pipe 5 respectively, enabling switching of the exhaust path. The exhaust port of the upper exhaust pipe 4 passes through the top wall and is located on the top of the vehicle, used to exhaust smoke to the outside of the cabin roof. The default exhaust method for the modular shelter is upper exhaust; the upper exhaust pipe 4 effectively exhausts smoke outside the vehicle, preventing it from entering the shelter and thus providing a good ergonomic environment.
[0023] The exhaust port of the lower exhaust pipe 5 passes through the bottom wall and is located at the bottom of the vehicle to exhaust smoke below the chassis. In combat operations, switching to the lower exhaust mode allows the lower exhaust pipe 5 to exhaust smoke below the chassis, avoiding infrared detection and thus improving the concealment and safety of the container vehicle.
[0024] In practical application, the sealing assembly includes at least one sealing plug, which is used to seal the smoke outlet of the upper smoke exhaust pipe 4 or the smoke outlet of the lower smoke exhaust pipe 5. In the upper smoke exhaust mode, the sealing plug seals the smoke outlet of the lower smoke exhaust pipe 5; when switching to the lower smoke exhaust mode, the sealing plug is detached from the smoke outlet of the lower smoke exhaust pipe 5 and seals the smoke outlet of the upper smoke exhaust pipe 4. The sealing plug and the smoke exhaust pipe are fixed by threaded connection, which is convenient for quick assembly and disassembly.
[0025] In practical application, the rain cover 2 is arranged at the smoke outlet position of the upper smoke exhaust pipe 4 on the roof, which is used to prevent rainwater from entering the upper smoke exhaust pipe 4 and protect the smoke exhaust system from rainwater erosion. The air outlet position of the upper smoke exhaust pipe 4 is also provided with a flow guide plate 3, which is used to guide the direction of the exhaust smoke flow and ensure that the smoke can be smoothly discharged outside the vehicle.
[0026] In practical application, the heat insulation assembly includes an asbestos board arranged on the outer wall of the smoke exhaust pipe, which is fixed on the outer wall of the smoke exhaust pipe by fasteners. The asbestos board is used to reduce the heat transfer to the vehicle body and protect the vehicle body from high-temperature smoke damage.
[0027] In practical application, the fixing assembly includes a clamp, which is used to fix the upper smoke exhaust pipe 4 on the vehicle body to ensure the stability and reliability of the smoke exhaust system.
[0028] In the use process of the device, when it is necessary to switch to the lower smoke exhaust mode, the operator can detach the sealing plug and install it on the air outlet of the upper smoke exhaust pipe 4 to seal the port of the upper smoke exhaust pipe 4, and then the lower smoke exhaust pipe 5 starts to exhaust smoke to the bottom plate, and the heat insulation assembly can reduce the heat transfer to the vehicle body and protect the vehicle body from high-temperature smoke damage.
[0029] The above embodiment is a preferred implementation scheme of the present application, in addition to this, the present application can also be realized in other ways, and any obvious replacement without departing from the technical scheme concept of the present application is within the scope of the present application patent.
[0030] In order to make the ordinary skilled in the art more conveniently understand the improvement of the present application over the prior art, some drawings and descriptions of the present application have been simplified, and some other elements have been omitted in the present application file for the sake of clarity, and the ordinary skilled in the art should realize that these omitted elements can also constitute the content of the present application.
