Description

Technical Field

[0001] This application relates to the field of mobile passenger booster technology in plateau areas, and particularly to a mobile passenger booster vehicle. Background Technology

[0002] The low pressure and low oxygen environment in high-altitude areas can cause people to experience varying degrees of altitude sickness. Currently, China has developed a high-altitude manned pressurized vehicle to alleviate the problem of altitude sickness. Its principle is to create a high-pressure sealed space and pressurize the air in the sealed space to reduce the equivalent altitude of the space to a level close to that of the plains, thereby increasing the oxygen content inhaled by the human body and effectively solving the problem of altitude sickness.

[0003] Mobile pressurized cabins are typically integrated with a motor vehicle chassis, allowing the cabin to be opened and used while the vehicle is in motion. Compared to hyperbaric oxygen chambers and towed mobile cabins, they offer advantages such as high integration, the ability to carry people, and usability during transit, making them a better method for treating and transporting people suffering from altitude sickness during journeys in high-altitude areas. Improving the safety performance of pressurized passenger vehicles is a prerequisite for their widespread adoption. Vehicles have high safety requirements when driving on roads, and various accidents that may occur on the road can adversely affect the sealed pressurized cabin; therefore, fire safety for pressurized passenger vehicles must be considered. Existing designs for pressurized passenger vehicles have incorporated fire escape mechanisms for accidents such as traffic collisions and fires. However, current designs do not address fire escape issues arising from electrical system failures such as power outages or short circuits in the pressurization system, or from pressurization failure in the sealed space due to oxygen deprivation within the cabin. Utility Model Content

[0004] This application provides a mobile passenger booster vehicle that effectively solves the safety problems of fire escape when the booster system fails due to electrical system failures such as power outages and short circuits, as well as the failure of booster in a confined space caused by oxygen deficiency and suffocation in the container.

[0006] Furthermore, the air quality detection system includes an air quality sensor and a first alarm, which are respectively connected to the controller.

[0007] Furthermore, at least two of the first alarm devices are provided, and they are respectively installed in the driver's cab and the pressurized cabin.

[0008] Furthermore, the air quality detection system also includes an air purifier, which is installed inside the pressurized chamber and connected to the controller.

[0009] Furthermore, the pressure relief valve includes a first manual pressure relief valve, a second manual pressure relief valve, and an automatic pressure relief valve. The first manual pressure relief valve and the automatic pressure relief valve are respectively disposed on the side wall of the pressurization chamber. The front end of the pressurization chamber shares a wall with the rear end of the cab, and the second manual pressure relief valve is disposed on the wall. The second manual pressure relief valve is opened or closed by the cab, and the automatic pressure relief valve is connected to the controller.

[0010] Furthermore, the short-circuit protection system includes a wire short-circuit protector.

[0011] Furthermore, the short-circuit power failure protection system also includes an emergency power supply and a power failure alarm. The power failure alarm is installed in the cab or pressurized compartment and connected to the power supply circuit.

[0014] Furthermore, the emergency passage includes a cab emergency passage located between the driver's cab and the pressurized compartment, and emergency escape windows located on opposite side walls of the pressurized compartment. The cab emergency passage can be opened from the pressurized compartment or the driver's cab, and the emergency escape windows can be opened from inside the pressurized compartment or from the outside.

[0015] The beneficial effects of the mobile passenger-carrying booster vehicle of this application are: Under pressurization conditions, it can effectively solve the problem of fire escape when the pressurization system fails due to power failure, short circuit or other electrical system failures, or when there are problems with the air environment inside the cabin, thus greatly improving the safety factor.

[0023] This application provides a mobile pressurized passenger vehicle designed to address the fire escape issues arising from the failure of existing mobile pressurized passenger vehicles to handle electrical system failures such as power outages or short circuits, as well as the failure of pressurization in a confined space due to oxygen deficiency. By monitoring the air quality inside the pressurized chamber 3 in real time, the vehicle enables emergency evacuation for personnel in cases of oxygen deficiency or poor air quality. Furthermore, it also enables emergency evacuation for personnel in the event of pressurization failure due to electrical system failures such as power outages or short circuits, significantly improving the safety performance of the pressurized vehicle.

[0024] For details, please refer to Figure 1The mobile passenger booster vehicle of this embodiment includes a motor vehicle chassis 1, a driver's cab 2 located at the upper front of the motor vehicle chassis 1, and a booster compartment 3 fixed at the upper rear of the motor vehicle chassis 1.

[0025] The pressurized chamber 3 has an access passage 31 that can be opened or closed from the inside and outside of either side wall. The access passage 31 includes a passage opening on the side wall and an airtight door installed at the passage opening, providing an entrance and exit for rescue and personnel to enter and exit the pressurized chamber 3.

[0026] The pressurized chamber 3 is equipped with an emergency passage that can be opened or closed. Specifically, multiple emergency passages are set on the side wall of the pressurized chamber 3 so that personnel inside the chamber can quickly respond to an emergency and leave the pressurized chamber 3 through the emergency passages.

[0027] A pressurization system connected to the pressurization chamber 3 is installed in the vehicle chassis 1 to pressurize and maintain the pressure inside the pressurization chamber 3, improve the pressure difference between the inside and outside of the pressurized vehicle, ensure that the air pressure inside the pressurization chamber 3 is similar to the pressure in low-altitude areas, create a low-altitude air pressure environment, and thus realize the rescue of personnel inside the chamber.

[0028] The pressurization chamber 3 is equipped with a pressure relief valve that allows pressure to be released to the outside. The pressure relief valve can quickly release pressure from the pressurization chamber 3, so that the air pressure inside and outside the pressurization chamber 3 can be quickly restored to a constant or low pressure difference.

[0029] An air quality detection system is installed in pressurized chamber 3 to monitor the air quality inside the chamber in real time. This system primarily monitors the oxygen and carbon dioxide levels inside the chamber. The air quality detection system is connected to a controller, providing real-time feedback of relevant air quality data and information.

[0030] In some embodiments, the air quality detection system includes an air quality sensor 41 and a first alarm 42, which are respectively connected to the controller. The air quality sensor 41 is installed in a suitable position inside the pressurized chamber 3 and mainly monitors the oxygen and carbon dioxide concentration indicators inside the pressurized chamber 3. Taking oxygen monitoring as an example, when the oxygen content inside the pressurized chamber 3 is lower than the safe value, the controller will immediately issue a command, and the first alarm 42 will sound an alarm to remind the driver, passengers, and occupants.

[0031] In addition, when the oxygen content in the pressurized chamber 3 is lower than the safe value, the pressure relief valve should be opened immediately to release the pressure, and the machine should be stopped quickly to vent the pressurized air in the pressurized chamber 3 to the outside. When the pressurized chamber 3 is stationary relative to the ground and the air pressure inside and outside the chamber is the same, the access passage 31 and the emergency passage can be opened for escape.

[0032] In some other embodiments, the air quality detection system also includes an air purifier, which is installed inside the pressurized chamber 3, powered by the vehicle's power supply, and connected to the controller. When the air quality detection system detects a decrease in oxygen content (above the safe value) and an increase in carbon dioxide concentration (above the set value), the controller activates the air purifier to purify the air inside the pressurized chamber 3.

[0033] However, it should be noted that if the air quality in the pressurized cabin 3 does not improve after a period of air purification, that is, the oxygen content continues to decrease and the carbon dioxide concentration continues to increase, then consider switching to "escape mode" to quickly depressurize the pressurized cabin 3 and allow the occupants to quickly escape to the outside of the vehicle through the emergency exit and access passage 31.

[0034] In this embodiment, see Figure 1 and Figure 2 The emergency passages include a cab emergency passage 32 located between the pressurized cabin 3 and the cab 2, and emergency escape windows 33 located on opposite side walls of the pressurized cabin 3.

[0035] In some application scenarios, the access passage 31 can be opened by the occupants inside the pressurized cabin 3 or by personnel from the outside, and the occupants inside the pressurized cabin 3 can escape from the pressurized cabin 3 through the access passage 31.

[0036] In some application scenarios, when the access passage 31 cannot be opened, the occupants in the pressurized cabin 3 can open the emergency passage 32 in the driver's cab from inside the cabin, or the occupants in the driver's cab 2 can open the emergency passage 32 in the driver's cab from outside the cabin. The occupants in the pressurized cabin 3 can escape from the emergency passage 32 in the driver's cab to the driver's cab 2, and then escape from the vehicle through the door of the driver's cab 2.

[0037] In some application scenarios, when the access passage 31 and / or the emergency passage 32 in the driver's cab cannot be opened, the occupants in the pressurized compartment 3 can open the emergency escape window 33 from inside the compartment, or the occupants in the driver's cab 2 can open the emergency escape window 33 from outside the pressurized compartment 3, and the occupants in the pressurized compartment 3 can escape to the outside of the vehicle through the emergency escape window 33.

[0038] In this embodiment, the pressurization system is connected to a controller via a power supply circuit. The controller is connected to the vehicle's power supply to control the power supply to the pressurization system. A short-circuit power-off protection system is connected to the power supply circuit. When a short circuit or power failure occurs in the power supply circuit, the short-circuit power-off protection system is triggered, immediately cutting off the power supply to the user's electrical appliances. The pressurization system uses a compatible pressurization device (such as a pressurization fan and pressurization piping connected to the pressurization fan). When the power supply circuit malfunctions, such as a short circuit or open circuit, the short-circuit power-off protection system will trigger the power-off protection immediately, considering switching to "escape mode" and quickly depressurizing the pressurization compartment 3. The occupants then quickly escape to the outside of the vehicle through the emergency exit and access passage 31.

[0039] In some embodiments, a pressure detector (using an appropriate pressure sensor) for detecting internal air pressure is also provided in the pressurization chamber 3. The pressure detector is connected to the controller to monitor the pressure change in the pressurization chamber 3 in real time. When the pressure change is lower than the set value, the controller controls the pressurization system to start quickly to pressurize the pressurization chamber 3. When the pressure returns to the set value, the controller controls the pressurization system to shut down.

[0040] However, it should be noted that when the pressure inside the pressurized compartment 3 drops rapidly or continues to drop to a safe level, the "escape mode" should be switched to, the pressurized compartment 3 should be depressurized quickly, and the occupants should quickly escape to the outside of the vehicle through the emergency exit and access passage 31.

[0041] In some embodiments, at least two first alarms 42 are provided, and are respectively installed in the driver's cab 2 and the pressurized cabin 3. Taking oxygen index monitoring as an example, when the oxygen content inside the pressurized cabin 3 is lower than the safe value, the controller will immediately issue a command, and all first alarms 42 will sound an alarm. The driver and passengers can be alerted immediately and quickly take emergency action, such as switching to "escape mode" to quickly depressurize the pressurized cabin 3, and the passengers can quickly escape to the outside of the vehicle through the emergency passage and the access passage 31.

[0042] In some embodiments, the pressure relief valve includes a first manual pressure relief valve 34, a second manual pressure relief valve 35, and an automatic pressure relief valve 36. The first manual pressure relief valve 34 and the automatic pressure relief valve 36 are respectively disposed on the side wall of the pressurization chamber 3. The front end of the pressurization chamber 3 shares a wall with the rear end of the cab 2, that is, the front side wall of the pressurization chamber 3 and the rear side wall of the cab 2 share a single wall surface. The second manual pressure relief valve 35 is disposed on the shared wall surface, and the automatic pressure relief valve 36 is connected to a controller. When pressure relief is required, pressure can be relieved by manually operating the first manual pressure relief valve 34 or the second manual pressure relief valve 35, or by simultaneously opening the first manual pressure relief valve 34 and the second manual pressure relief valve 35 to quickly relieve pressure, or by automatically opening the automatic pressure relief valve 36 to relieve pressure.

[0043] In some application scenarios, refer to Figure 3 When the air quality detection system detects a problem with the air quality inside the pressurized cabin 3 (oxygen concentration below the safe value, carbon dioxide concentration above the safe value), it will quickly trigger automatic depressurization. The controller will quickly activate the automatic depressurization valve 36 to release pressure based on the signal fed back by the air quality detection system. After the depressurization is completed, the occupants will quickly switch to "escape mode" to quickly depressurize the pressurized cabin 3. The occupants will then quickly escape to the outside of the vehicle through the emergency exit and access passage 31.

[0044] In some application scenarios, refer to Figure 3When a short circuit or open circuit is detected in the power supply circuit, the controller quickly activates the automatic pressure relief valve 36 to release pressure. After the pressure is released, the occupants quickly switch to "escape mode" to quickly release pressure in the pressurized compartment 3. The occupants then quickly escape to the outside of the vehicle through the emergency passage and the access passage 31.

[0045] It should be added that while the automatic pressure relief valve 36 is releasing pressure, the first manual pressure relief valve 34 and the second manual pressure relief valve 35 can be opened manually to release pressure together and shorten the pressure relief time.

[0046] In some embodiments, see Figure 3 The short-circuit protection system includes a wire short-circuit protector. This wire short-circuit protector uses an existing product of a compatible model and is connected to the power supply circuit. When a short circuit occurs in the power supply circuit inside the pressurized compartment 3, the wire short-circuit protector is triggered, cutting off the power supply from the vehicle power supply to the power supply circuit inside the pressurized compartment 3.

[0047] In some embodiments, see Figure 3 The short-circuit power failure protection system also includes an emergency power supply 37 and a power failure alarm 38, with the emergency power supply 37 connected to the power failure alarm 38. When the power supply circuit inside the pressurized chamber 3 fails, the emergency power supply 37 supplies power to the power failure alarm 38, and simultaneously triggers the power failure alarm 38 to issue an alarm notification.

[0048] The power failure alarm 38 is installed in the driver's cab 2 or the pressurized cabin 3 so that the driver and passengers can receive the alarm notification immediately.

[0049] In this embodiment, the emergency power supply 37 is installed in the vehicle chassis 1, the driver's cab 2, or the pressurized compartment 3.

[0050] In some embodiments, a cab alarm 39 is also included. The cab alarm 39 is connected to a controller and, together with the power failure alarm 38 and the first alarm 42, forms an alarm and escape evacuation system. The specific alarm and escape procedures are as follows (see reference). Figure 3 : When the power supply circuit inside the pressurization chamber 3 is short-circuited, the short-circuit protector is automatically triggered to cut off the power supply, and then the power failure alarm 38 is automatically triggered to issue an alarm prompt; when the air quality index inside the pressurization chamber 3 is detected to exceed the safe value (or the set value), the first alarm 42 is automatically triggered to issue an alarm prompt.

[0051] Furthermore, when either the power failure alarm 38 or the first alarm 42 is triggered, the cab alarm 39 is activated, issuing an alarm notification. When either the power failure alarm 38 or the first alarm 42 is triggered, the automatic pressure relief valve 36 inside the pressurized compartment 3 is activated, venting the pressurized air inside the pressurized compartment 3 outside.

[0052] Simultaneously, when the alarm 39 in the driver's cab sounds, the occupants in the driver's cab 2 manually apply the brakes to stop the mobile pressurized passenger vehicle. Once the vehicle brakes to a stop and the gas in the pressurized chamber 3 is depressurized to the same level as the outside air pressure, the occupants in the pressurized chamber 3 can open the access passage 31 from inside the chamber, or from the outside, allowing them to escape from the pressurized chamber 3.

[0053] In some embodiments, the pressurized chamber 3 is equipped with a separate oxygen inhalation chamber. The side wall of the oxygen inhalation chamber is provided with an airtight door that can be opened or closed, through which other areas of the pressurized chamber 3 can be accessed. The vehicle chassis 1 or the oxygen inhalation chamber is equipped with an oxygen supply system (a prior art system, which will not be described in detail here). The oxygen supply system is connected to the interior of the oxygen inhalation chamber and is connected to the controller. This oxygen supply system can be used for people who need oxygen inhalation. These people enter the oxygen inhalation chamber from the pressurized chamber 3, and the oxygen-rich environment in the oxygen inhalation chamber can alleviate their hypoxia symptoms.

[0054] Of course, the oxygen inhalation room can be equipped with an oxygen cylinder for emergency use when the demand for oxygen is high.

[0055] In some embodiments, the pressurization chamber 3 is equipped with user-end electrical appliances connected to the power supply circuit. These user-end electrical appliances include lighting, a humidifier, an air conditioner, and other electrical components installed in the pressurization chamber 3. They provide lighting and improve air humidity and temperature. The user-end electrical appliances can be powered by an emergency power supply 37.

[0056] Compared with the prior art, this utility model has significant advantages and beneficial effects, specifically reflected in the following aspects: 1. Equipped with automatic identification and alarm functions for accidents such as short circuits, power outages, and oxygen deficiency / asphyxiation in the pressurized cabin. When a short circuit, power outage, or oxygen deficiency / asphyxiation accident occurs in the circuit of the mobile pressurized cabin, the system will automatically detect the accident and automatically activate alarms in the driver's cab and the pressurized cabin. This system has excellent automatic monitoring and alarm functions for the pressurized cabin circuit during operation, reducing manual operation steps for personnel in case of accidents and improving the safety warning performance of the mobile pressurized cabin.

[0057] 2. Equipped with an automatic depressurization function for the pressurized space. In the event of an accident such as a short circuit, power outage, or oxygen deprivation and asphyxiation in the pressurized cabin, the depressurization valve is automatically activated to reduce the air pressure in the mobile pressurized cabin to the level of the outside environment. This function provides the necessary escape conditions for the occupants of the mobile pressurized cabin to open evacuation routes and escape, thus improving the escape speed.

[0058] 3. The pressurized cabin has multiple escape routes, including entrance and exit routes, emergency exit routes, and emergency escape windows, all of which can be opened from inside or outside the mobile pressurized cabin. They can be operated entirely mechanically without the need for electrical control, which significantly improves the escape probability of the mobile pressurized cabin in the event of an electrical fire accident.

[0059] 4. In the event of a power outage or short circuit, it can be operated entirely manually. In the event of an accident, the driver's cab can be manually braked, the mobile pressurized cabin can be manually depressurized, and all four safety escape routes can be manually opened. The purely manual operation ensures the safety performance of the mobile pressurized cabin in the event of a fire.
