Description

Technical Field

[0001] This utility model relates to a heating device, particularly an auxiliary heating device for armored vehicles, and belongs to the field of heating technology. Background Technology

[0002] Currently, to meet the needs of combat readiness in extremely cold regions and ensure the safety of crew members, many types of tracked mobile equipment are required to be equipped with heating devices to prevent frostbite. Furthermore, when operating in high-altitude and frigid regions, electrical components and chips in the equipment have safety requirements regarding their operating temperature range. In addition, in modern warfare, various unforeseen events occur frequently. For example, if an enemy shell explodes near a vehicle, the resulting smoke and toxic gases will disperse around the armored vehicle. Or, if the enemy releases viruses or bacteria, the environment will deteriorate. In such cases, the air entering the armored vehicle must be purified; otherwise, the safety of the crew will be endangered. Current equipment does not classify and differentiate between four environmental states: smoke and gas, polluted gas, toxic gas, and good air. Instead, it simply closes or opens the air inlet, adopting a one-size-fits-all approach. This approach fails to provide the most suitable riding environment for armored vehicles with minimal effort and results in energy waste.

[0003] Chinese patent application number 202011330188.8, entitled "A Heater for New Energy Vehicles," discloses a technical solution for adding a heater to a vehicle. The heater includes a shell, a combustion chamber, a motor, and a fan. The motor is fixed to one end of the shell, with a speed sensor at the end furthest from the shell, and the other end extending into the shell and connected to the fan. The combustion chamber is a hollow cylinder with an opening at one end and an air vent at the other. A sealing plate is located around the outer edge of the combustion chamber near the air vent, dividing the shell into an air chamber and a combustion chamber. An air inlet pipe and an exhaust pipe are connected to one side of the shell, which also houses a controller and a temperature sensor. It heats the combustion chamber by burning diesel fuel and transfers the heat to water in a heat exchange tube, meeting the heating needs. While this invention addresses the heating requirements of passengers, it does not address the need for optimal matching by selecting different filters for different air conditions.

[0004] Furthermore, existing technologies require occupants to exit the vehicle and close the air intake and exhaust vent covers when switching between operating modes. This is not only time-consuming and labor-intensive but also increases the probability of injury. Consequently, the occupant heating devices can only be used when the vehicle is parked in a garage and stationary. If supplies are loaded and secured to racks, they will completely block the air intake and exhaust vents of the occupant heaters, rendering them inoperable. This drawback not only affects vehicle performance but also deteriorates the working environment for occupants. Additionally, in viral environments, toxic gases from outside can enter the vehicle through the air intake and exhaust vents of the occupant heaters. When protection is needed, occupants must exit the vehicle and close the air intake and exhaust vent covers, which is not only time-consuming and labor-intensive but also increases the probability of injury. This renders the devices unusable in nuclear, biological, and chemical (NBC) environments. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an armored personnel carrier suitable for long-distance transport in harsh environments, which addresses the shortcomings of existing technologies. It can provide a warm working environment for the crew in frigid areas and a healthy breathing environment in dusty, polluted or toxic environments. In addition, the switching of various working states can be completed inside the vehicle.

[0006] The technical problem to be solved by this utility model is solved by the following technical solution: An armored personnel carrier suitable for long-distance transport in harsh environments is provided. The vehicle is equipped with a heating device and an exhaust system, including a burner and an air filter assembly. The air filter assembly is connected to the burner's air inlet via an intake pipe. The air filter assembly includes a dust filter, a dirt-resistant filter, a chemical-resistant filter, and a solenoid valve DCF1. The dust filter, dirt-resistant filter, and chemical-resistant filter are connected in series in the air filter pipeline. The input end of the dust filter is connected to an air inlet. The air filter pipeline and the intake pipe are connected at the dust filter input end. A solenoid valve DCF1 is connected between the output pipes of the anti-fouling filter and the dust filter, and the intake pipe, respectively. A solenoid valve DCF2 and a solenoid valve DCF3 are connected in parallel between them. The output of the chemical-resistant filter is connected to a solenoid valve DCF4. The first output of the solenoid valve DCF4 is connected to the intake port through a solenoid valve DCF5, and the second output is connected to the vehicle's intake port through an intake pipe. The anti-fouling filter is composed of alternating layers of activated carbon and insulating pads. The dust filter is composed of multiple layers of filter paper.

[0007] The aforementioned armored personnel carrier suitable for long-distance transport in harsh environments includes a burner with heat exchange tubes arranged on the outside of the combustion chamber, and radiators connected to both ends of the heat exchange tubes. The burner includes a combustion chamber and a motor, with the motor fixedly mounted on one side of the burner and a fan connected to one end. The fan has a protective cover fixedly connected to the burner, and an air inlet is provided on the outer ring of the fan. An exhaust port is connected to one side of the combustion chamber.

[0014] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0015] This utility model provides a heating device and exhaust system accessory on the armored personnel carrier, including a burner and an air filter assembly, to ensure that the armored personnel carrier can operate stably regardless of environmental influences.

[0016] The air filtration assembly includes a dust filter element 6, a dirt-resistant filter element 7, a chemical-resistant filter element 8, and a solenoid valve DCF1. The dust filter element, dirt-resistant filter element, and chemical-resistant filter element are connected in series in the air filtration pipeline, and can filter the air to a level acceptable to the human body, either individually or in combination. The input end of the dust filter element 6 is connected to the air inlet 9. When the ambient air is dusty, the outside air first enters the dust filter element 6 for filtration. A solenoid valve DCF1 is connected between the air filtration line 19 at the input end of the dust filter element 6 and the air intake line 1. Solenoid valve DCF1 controls whether external air is used directly without filtration by the dust filter element 6, thus saving energy (the energy required to overcome the pipeline resistance during air intake is provided by the motor 11 and fan 12). Solenoid valves DCF2 and DCF3 are connected between the air filtration lines 19 at the output ends of the anti-fouling filter element 7 and the dust filter element 8 and the air intake line 1, respectively. Solenoid valve DCF2 controls whether the air filtered by the dust filter element 6 needs further filtration before entering the air intake line 1; that is, solenoid valve DCF3 controls whether secondary filtered air is used in the air intake line 1. The output end of the chemical protective filter element 8 is connected to a solenoid valve DCF4, the other end of which is connected to the air intake line 1. The air intake line 1 delivers clean air into the vehicle for the occupants to breathe. The air intake line 1 also directs air to the burner via a solenoid valve DCF5 to provide combustion support.

[0017] The filter element of this utility model is divided into four types: First, there are multi-layered filter cartridges, which remove dust, debris, and flying insects. These use multiple layers of filter paper. Second, there are anti-fouling filter cartridges, which block polluted air, such as polluted gases emitted from factories, fumes from explosions, acidic gases, volatile organic compounds (VOCs), and toxic particulate matter. Inhaling these harmful components can cause serious damage. Anti-fouling filter cartridges use activated carbon made from wood, fruit shells, etc. The activated carbon can be made into cakes or adhered to porous materials to form filter cloth, which is then stacked into multiple layers to improve adsorption capacity. Third, there are chemical-resistant filter cartridges, primarily used for polluted gases such as acidic gases, VOCs, bacteria, viruses, or radioactive particles. Its filter element uses multiple stacked elements, such as chemically treated activated carbon, such as those impregnated with metal oxides like copper, silver, zinc, platinum, and palladium, which can adsorb and catalytically decompose toxic gases like hydrogen cyanide and hydrogen sulfide; filter elements impregnated with sodium hydroxide can filter out acidic toxic gases like chlorine and phosgene; filter elements using HEPA filter paper can block bacteria, viruses, or radioactive particles; and if a photocatalyst is used, nano-titanium dioxide is used as a photocatalyst, which generates highly oxidizing hydroxyl radicals and oxygen under light irradiation, which are used to decompose organic compounds, bacteria, and viruses, thus purifying the air.

[0018] Because there are many different types of toxic substances, in order to achieve a comprehensive purification effect, this utility model adopts a multi-layer fiber mesh to combine multiple filter elements of different types into one.

[0019] The air filter assembly is connected to the air inlet 2 of the burner via the air inlet pipe 1, which delivers filtered air into the burner to provide combustion support. Heat exchange tubes 4 are arranged on the outer side of the combustion chamber 3 of the burner. Diesel fuel enters the combustion chamber through the fuel inlet 16 and is ignited by the igniter plug 15. The diesel fuel burns in the combustion chamber 3, generating a large amount of heat energy. The two ends of the heat exchange tubes 4 are connected to the radiator 5, transferring heat to the radiator 5. The burner includes the combustion chamber 3 and a motor. The motor is fixed to one side of the burner, and a fan is driven to one end of it. A protective cover is provided around the fan, and an air inlet is provided on the cover. An exhaust port is connected to one side of the combustion chamber, and the exhaust port is connected to the exhaust window through a pipe. The exhaust port is used to exhaust the combusted exhaust gas through the pipe to the exhaust window, and finally to the outside of the vehicle. The combustion chamber is a hollow cylinder with one open end. An igniter plug and a fuel inlet are provided inside the combustion chamber for the combustion of diesel fuel.

[0020] In this invention, the switching of various types of filter elements is controlled by the CPU. The control board is equipped with a first button AJ1 to a fourth button AJ4, which correspond to the switching control of the first solenoid valve DCF1 to the fourth solenoid valve DCF4, respectively.

[0021] When personnel inside the vehicle need to switch the air filtration mode to observe the external situation, they can press one or more of the buttons AJ1-AJ4 (control switches). The CPU will then instruct solenoid valves DCF1-DCF4 to close or open respectively, resulting in different filtration effects. For example, when solenoid valve DCF1 is closed, the air first undergoes primary filtration through dust filter 6, filtering out dust, debris, and flying insects. If there is contaminated gas such as smoke in the air, solenoid valve DCF3 can be opened and DCF2 closed, allowing the filtered air to pass through anti-fouling filter 7 for further filtration. If contaminated gas is still present in the air, it undergoes secondary filtration through anti-fouling filter 7. If toxic gas is present in the air after a poison gas explosion, it undergoes a third filtration through chemical protective filter 8, filtering out volatile organic compounds, bacteria, viruses, or radioactive particles before entering the armored vehicle to ensure the breathing safety of the crew.
