Description

Technical Field

[0001] This invention relates to the field of ambulance technology, and in particular to an emergency medical platform for engineering operations in high-altitude areas. Background Technology

[0002] In recent years, as China Southern Power Grid has undertaken high-voltage transmission projects in high-altitude regions such as Yunnan, Guizhou, Tibet, and Qinghai, and with the altitude of these projects gradually increasing, hundreds of thousands of power construction and maintenance personnel have been relocated to ultra-high-altitude areas. They are facing a combination of challenges, including oxygen deficiency and low temperatures. The unique requirements of high-altitude power grid operations, such as transmission line maintenance and substation inspections, are exacerbated by the rugged terrain and inconvenient transportation, making rescue efforts extremely difficult. Without proper precautions, these operations can easily lead to acute or chronic altitude sickness, seriously endangering the physical and mental health of the workers.

[0003] The emergency rescue platform for engineering operations in plateau areas is a medical rescue equipment designed specifically for high-altitude and extreme environments. Its core objective is to solve the occupational health protection problem for engineering personnel in power, infrastructure and other fields working in plateau areas.

[0004] Currently, when conducting emergency transport and rescue of patients working on engineering projects in high-altitude areas, challenges such as low atmospheric pressure (only 60-70% of that at sea level), thin air, and unstable airflow must be considered, leading to a decrease in the efficiency of the negative pressure system inside the ambulance: Firstly, the long-term low air pressure in the high-altitude environment reduces the suction efficiency of the exhaust fan, making it difficult to quickly establish a stable negative pressure, resulting in insufficient negative pressure inside the vehicle and failure to isolate pathogens; secondly, during rapid travel, fluctuations in vehicle speed and wind speed cause turbulence, resulting in uneven airflow distribution, which traditional fixed air ducts cannot adapt to, easily forming a positive pressure zone at the bottom, increasing the risk of leakage. Furthermore, the sudden changes in air pressure in the high-altitude environment mean that static systems cannot respond quickly to leaks, resulting in lower safety and adaptability; at the same time, the thin air weakens the effect of ultraviolet disinfection, and residual airflow dead zones cause pollutants to accumulate at the bottom of the vehicle, exacerbating the risk of cross-infection and reducing the reliability of ambulances in extreme environments. Summary of the Invention

[0005] This application provides an emergency rescue platform for engineering operations in high-altitude areas, which solves the technical problems in existing technologies such as difficulty in establishing negative pressure in low-pressure environments, leakage risks caused by uneven airflow distribution leading to pathogen isolation failure, decreased disinfection performance leading to pollutant accumulation, increased risk of cross-infection, and response delays lacking dynamic adaptability. It achieves the technical effects of rapidly establishing negative pressure in low-pressure environments, uniform airflow distribution to reduce leakage risks and prevent pathogen isolation failure, improved disinfection performance to prevent pollutant accumulation, reduced risk of cross-infection, rapid response to improve dynamic adaptability, and remote environmental reconnaissance, emergency material delivery, and real-time communication and command functions through the integration of a drone system to improve the efficiency of emergency rescue for power grid projects in high-altitude areas under extreme environments.

[0006] This application provides an emergency rescue platform for engineering operations in plateau areas, including an ambulance body, a fan and an air intake unit for extracting air from the ambulance body; The air intake unit is provided in multiple sets, which are arranged around the side wall of the ambulance. Each air intake unit includes a fresh air frame, a blade, an opening and closing component for controlling the opening and closing of the blade, an exhaust fan, an ultraviolet disinfection lamp, an air purification layer and an air duct. Each of the aforementioned fresh air frames has multiple ventilation holes evenly arranged from top to bottom on its inner sidewall. Each ventilation hole is connected to an air duct. Each of the aforementioned air ducts has a tree-like structure, consisting of a main pipe, a connecting pipe, and multiple branch pipes. Each branch pipe is connected to the main pipe through a connecting pipe. Branch pipes located at different positions use electromagnetic force to quickly and accurately compensate for negative pressure in areas where leakage occurs or where negative pressure is too low, in order to maintain the overall negative pressure state inside the vehicle.

[0007] Preferably, the ambulance is equipped with a workbench, a roof-mounted air conditioner, an information collection window, a desk, a medical waste bin, and a medical refrigerator to meet the engineering rescue needs under different conditions.

[0008] Preferably, the two air ducts corresponding to the inner sides of the front and rear side walls and the left and right side walls of the ambulance are arranged in an alternating manner to increase the negative pressure convection inside the vehicle, so that the overall negative pressure inside tends to be stable.

[0009] Preferably, the middle section of the main pipe is made of a flexible and highly elastic material. When the incoming external wind is strong, the middle section of the main pipe expands due to the influx of airflow, forming a "bladder-like buffer section" to achieve a smooth airflow transition.

[0010] Preferably, the ambulance body sidewall has multiple sets of channels for placing air ducts. The channels are sealed to the fresh air frame. Each set of channels includes a main channel and multiple sets of secondary channels. The main channel corresponds one-to-one with the main pipe, and the secondary channels correspond one-to-one with the branch pipes.

[0011] Preferably, the opening area of ​​each set of secondary channels and their corresponding branch pipes increases sequentially from top to bottom, in order to ensure that the airflow inside the vehicle gathers from all sides inward under the negative pressure of the exhaust fan, and is completely extracted from bottom to top by the exhaust fan after disinfection, thus preventing leakage.

[0012] Preferably, the branch pipe is provided with two sections, namely a fixed section and a movable section; The fixed section is fixed in the secondary channel by a mounting base, and the movable section is slidably connected to the end of the fixed section; The movable section is a multi-stage telescopic structure. A magnetic ring is fixed inside the first-stage telescopic section away from the fixed section, and an electromagnetic ring is fixed inside the fixed section. The extension and retraction of the movable section are controlled by magnetic force, thereby enabling precise positioning and rapid negative pressure compensation of a certain area inside the vehicle.

[0013] Preferably, the middle part of the fixed section is a flexible section, which is made of flexible material and has a metal strip on its outer side; an electromagnetic ring is embedded in the secondary channel at the position corresponding to the flexible section, and the expansion degree of the flexible section is controlled by magnetic attraction.

[0014] Preferably, the ambulance body has multiple sensors evenly arranged on its inner sidewall for detecting negative pressure in a certain area inside the vehicle.

[0015] Preferably, the magnetic properties and on / off states of electromagnetic ring one and electromagnetic ring two are controlled by an external control system. When a negative pressure abnormality or leakage occurs in a certain area of ​​the vehicle, the sensor in that area transmits the pressure information to the external control system. Then, the external control system controls the on / off state of electromagnetic ring one and the magnetic properties and magnetic force of electromagnetic ring two in that area, so that the moving section of the corresponding branch pipe can quickly extend to the leakage position and control the expansion state of the flexible section, thereby achieving rapid negative pressure compensation for that area to maintain the overall negative pressure state inside the vehicle.

[0016] One or more technical solutions provided in this application have at least the following technical effects or advantages: The system achieves uniform air intake distribution through multiple circumferential air intake units, avoiding dead airflow zones caused by low pressure at high altitudes. A tree-like duct and branch pipes enable multi-level airflow distribution, enhancing the stability of negative pressure convection within the vehicle. Magnetic control of the branch pipe's moving section enables rapid leak point location and negative pressure compensation, improving dynamic response speed. Flexible main pipe sections buffer airflow pulses, resisting high-altitude wind pressure fluctuations. Sensors and an external control system enable real-time negative pressure monitoring and adaptive adjustment, preventing pathogen leakage. This effectively solves the technical problems of existing technologies, such as difficulty in establishing negative pressure in low-pressure environments, leakage risks due to uneven airflow distribution leading to pathogen isolation failure, decreased disinfection performance causing pollutant accumulation, increased risk of cross-infection, and lack of dynamic adaptability due to response delays. The system achieves rapid negative pressure establishment in low-pressure environments, uniform airflow distribution to reduce leakage risks and prevent pathogen isolation failure, improved disinfection performance to prevent pollutant accumulation, reduced risk of cross-infection, rapid response to enhance dynamic adaptability, and improved emergency rescue efficiency for power grid projects in high-altitude areas under extreme environments through integrated drone systems for remote environmental reconnaissance, emergency material delivery, and real-time communication command.

However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to enable a more thorough and complete understanding of the disclosure of the present invention.

[0032] Please see Figure 1 This is a schematic diagram of the overall structure of an emergency rescue platform for engineering operations in plateau areas according to the present invention. The protective negative pressure ambulance for engineering operations in plateau areas utilizes multiple circumferential air intake units 200 to achieve uniform air intake distribution, avoiding airflow dead zones caused by low pressure at high altitudes. Through tree-shaped air ducts 230 and branch pipes 232, multi-level airflow distribution is achieved, enhancing the stability of negative pressure convection within the vehicle. Magnetic control of the moving section 250 of the branch pipe 232 enables rapid leak point location and negative pressure compensation, improving dynamic response speed. The flexible main pipe section 231 buffers airflow pulses, resisting high-altitude wind pressure fluctuations. Sensors and an external control system enable real-time negative pressure monitoring and adaptive adjustment, preventing pathogen leakage. The invention achieves the following technical effects: rapid establishment of negative pressure in low-pressure environments; uniform airflow distribution to reduce leakage risk and prevent pathogen isolation failure; improved disinfection performance to prevent pollutant accumulation; reduced risk of cross-infection; rapid response to improve dynamic adaptability; and integration of an unmanned aerial vehicle system to achieve remote environmental reconnaissance, emergency material delivery, and real-time communication command functions, thereby improving the emergency rescue efficiency of power grid engineering in high-altitude areas under extreme environments.

[0033] Example 1: As Figures 1 to 7 As shown, this application discloses an emergency rescue platform for engineering operations in plateau areas, including an ambulance body 100, an exhaust fan 110 for extracting air from the ambulance body 100, and an air intake unit 200. The air intake unit 200 is provided in multiple sets, which are respectively arranged around the side wall of the ambulance body 100. Each air intake unit 200 includes a fresh air frame 210, a blade, an opening and closing component for controlling the opening and closing of the blade, an exhaust fan, an ultraviolet disinfection lamp, an air purification layer 220 and an air duct 230. Each of the fresh air frames 210 has multiple ventilation holes 211 evenly arranged from top to bottom on its inner sidewall. Each ventilation hole 211 is connected to the air duct 230. Each air duct 230 has a tree-like structure, consisting of a main pipe 231, a connecting pipe, and multiple branch pipes 232. Each branch pipe 232 is connected to the main pipe 231 through the connecting pipe. The branch pipes 232 located at different positions use electromagnetic force to quickly and accurately compensate for negative pressure in areas where leakage occurs or where the negative pressure is too low, so as to maintain the overall negative pressure state inside the vehicle.

[0034] like Figure 1 As shown, the ambulance body 100 is equipped with a workbench 101, a roof-mounted air conditioner 102, an information collection window 103, a desk 104, a medical waste bin 105, and a medical refrigerator 106 to meet the engineering rescue needs under different conditions.

[0035] like Figures 2 to 6 As shown, the two air ducts 230 on the front and rear side walls and the inner sides of the left and right side walls of the ambulance body 100 are arranged in an alternating manner to increase the negative pressure convection inside the vehicle, so that the overall negative pressure inside tends to be stable.

[0036] This application utilizes multiple circumferentially arranged air intake units 200 in conjunction with tree-shaped air ducts 230. The air ducts 230 are configured as a tree structure, divided into a main pipe 231, connecting pipes, and multiple branch pipes 232. The branch pipes 232 are connected to the main pipe 231 through the connecting pipes, forming a hierarchical network. This allows external air to be drawn in through the ventilation holes 211 of the fresh air frame 210 and diffused at multiple points through the branch pipes 232 of the tree-shaped air ducts 230. This results in multi-directional convection of airflow inside the vehicle, avoiding dead zones caused by a single air intake point. Furthermore, the tree-shaped branch pipes 232, like a "capillary network," increase the airflow contact surface. Through the Bernoulli effect, high-speed airflow can generate low-pressure suction at the branches, aiding in uniform distribution and increasing air intake density and uniformity, thus promoting the rapid establishment of a negative pressure field inside the vehicle. The tree-shaped structure refines the airflow path, improves air mixing efficiency, solves the problem of difficulty in establishing negative pressure and dead zones caused by low air pressure at high altitudes, and enhances the system's adaptability under low pressure.

[0037] By staggering the air ducts 230 inside the front and rear side walls and left and right side walls of the ambulance body 100, the staggered layout allows airflow to enter from multiple directions, forming complex turbulence inside the vehicle. This promotes thorough air mixing, avoids dead air zones, and prevents pressure gradient imbalance caused by wind speed fluctuations during high-speed driving. It can solve the leakage risk caused by uneven airflow distribution due to airflow stripping and dead zones that are prone to occur in fixed linear ventilation ducts in high-altitude and windy environments. The staggered convection stabilizes the negative pressure.

[0038] like Figures 6 to 8 As shown, the middle section of the main pipe 231 is made of a flexible and highly elastic material. When the incoming external wind is strong, the middle section of the main pipe 231 expands due to the influx of airflow, forming a "bladder-type buffer section" to achieve a smooth transition of airflow.

[0039] This application modifies the structure of the main pipe 231 by using a flexible, highly elastic material in its middle section to form a "bladder-type buffer section". Therefore, when the external airflow impacts the middle pipe section, its elastic deformation absorbs kinetic energy. The expansion and contraction of the middle pipe section smoothly smooths the airflow pulse. When it resets, it releases energy, buffers instantaneous wind pressure fluctuations, prevents the "wind hammer" effect, maintains air intake stability, solves the problem of negative pressure sudden change caused by unstable airflow, and improves the robustness of the system.

[0040] like Figures 4 to 6 , Figure 9 As shown, the ambulance body 100 has multiple sets of channels inside the side wall for placing air ducts 230. The channels are sealed to the fresh air frame 210. Each set of channels includes a main channel 201 and multiple sets of secondary channels 202. The main channel 201 corresponds one-to-one with the main pipe 231, and the secondary channels 202 correspond one-to-one with the branch pipes 232.

[0041] The opening area of ​​each set of secondary channels 202 and its corresponding branch pipes 232 increases from top to bottom, which is used to ensure that the airflow inside the vehicle gathers from all sides to the inside under the negative pressure of the exhaust fan 110, and is completely extracted from bottom to top by the exhaust fan 110 after disinfection, to prevent leakage.

[0042] This application utilizes the gradient change in the opening area of ​​the secondary channel 202 and the corresponding branch pipe 232, i.e., the opening area of ​​the secondary channel 202 and the corresponding branch pipe 232 increases sequentially from top to bottom, thereby reducing the air intake resistance at the bottom and allowing airflow to preferentially enter from the bottom. Therefore, under the negative pressure suction of the exhaust fan 110, a bottom-up "piston flow" is formed, guiding the airflow to flush upwards from the bottom of the vehicle, preventing pollutant deposition. At the same time, it enhances the negative pressure compensation at the bottom, which can solve the problem of pollutant accumulation and leakage caused by dead airflow at the bottom of the vehicle, optimize disinfection efficiency, ensure sufficient air intake at the bottom, and, combined with gravity, prevent cold air from stagnating.

[0043] like Figures 6 to 11 As shown,Figure 10 and Figure 11 The moving segment 250 shown in the figure is a simplified version of the multi-stage telescopic structure. The overall structure of the multi-stage telescopic structure is not fully shown in the figure.

[0044] The branch pipe 232 is provided with two sections, namely a fixed section 240 and a movable section 250; The fixed section 240 is fixed in the secondary channel 202 by a mounting base, and the movable section 250 is slidably connected to the end of the fixed section 240. The movable section 250 is a multi-stage telescopic structure. A magnetic ring 251 is fixed in the first-stage telescopic section away from the fixed section 240, and an electromagnetic ring 252 is fixed inside the fixed section 240. The extension and retraction of the movable section 250 are controlled by magnetic force, thereby accurately positioning and quickly compensating for negative pressure in a certain area inside the vehicle.

[0045] The fixed section 240 has a flexible section 241 in the middle, which is made of flexible material and has a metal strip 242 on its outer side; an electromagnetic ring 260 is embedded in the sub-channel 202 at the position corresponding to the flexible section 241, and the expansion degree of the flexible section 241 is controlled by magnetic attraction.

[0046] Multiple sensors for detecting negative pressure in a certain area inside the ambulance body 100 are evenly arranged on the inner side wall.

[0047] The magnetic properties and on / off states of the electromagnetic ring 260 and electromagnetic ring 252 are controlled by an external control system. When a negative pressure abnormality or leakage occurs in a certain area of ​​the vehicle, the sensor in that area transmits the pressure information to the external control system. Then, the external control system controls the on / off state of the electromagnetic ring 260 and the magnetic properties and magnetic force of the electromagnetic ring 252 in that area, so that the moving section 250 of the corresponding branch pipe 232 quickly extends to the leakage position and controls the expansion state of the flexible section 241, thereby achieving rapid negative pressure compensation for that area to maintain the overall negative pressure state inside the vehicle.

[0048] This application utilizes the moving section 250 of the branch pipe 232 and an electromagnetic control system. When the sensor detects an abnormal negative pressure in a certain area, the external control system energizes the second electromagnetic ring 252, generating the same magnetism as the magnetic ring 251. This repels the magnetic ring 251 and pushes the moving section 250 out. Furthermore, the magnetic attraction force can be adjusted by the energizing duration of the second electromagnetic ring 252 to achieve micro-displacement and adapt to different leakage scales. Simultaneously, the first electromagnetic ring 260 controls the expansion of the flexible section 241 to adjust the airflow, achieving targeted negative pressure compensation for the leak point. Therefore, when the air pressure changes suddenly at high altitudes, it can quickly compensate for leaks, solving the problem of response delay and lack of dynamic adaptability, and effectively preventing the leakage of pathogens.

[0049] The ambulance body 100 can also be equipped with a hyperbaric oxygen chamber as an independent modular space. Through oxygen generation, it achieves precise hyperbaric oxygen therapy, which can improve the patient's blood oxygenation. During transport, it can work in conjunction with the intelligent collaborative control of the negative pressure system to simultaneously complete hyperbaric oxygen therapy. This makes the device suitable for pre-hospital intervention for high-altitude-specific conditions such as acute carbon monoxide poisoning and traumatic brain injury with cerebral edema. The sensor is a differential pressure sensor, used to directly monitor the pressure difference values ​​in different areas inside the vehicle to support dynamic negative pressure adjustment in high-altitude environments. In the negative pressure system of this application, the differential pressure sensor is used to compare the difference between the pressure inside the vehicle and the atmospheric pressure outside, thereby directly reading the negative pressure value. The external control... The control system, used to coordinate the operation of electromagnetic ring 260 and electromagnetic ring 252, is preferably a programmable logic controller. The differential pressure sensor outputs digital electrical signals corresponding to real-time pressure data. The signals are transmitted to the external control system via wired or wireless means (using shielded cables for transmission to prevent electromagnetic interference), ensuring continuous monitoring of the negative pressure state and providing a data basis for subsequent control. After receiving the sensor signals, the external control system performs A / D conversion and filtering, identifies the location and severity of abnormal areas, calculates the required compensation amount based on a preset algorithm, and triggers the on / off command of the corresponding electromagnetic ring to achieve precise control. All of these are existing technologies and will not be described in detail here.

[0050] Specifically, considering the complex terrain, low air pressure, and easily obstructed transportation in high-altitude areas, the ambulance is equipped with a drone storage compartment on its roof. This drone system, serving as a rescue auxiliary module, can be activated in real time and automatically released from the roof according to different rescue needs in various environments. Specifically, the drone is equipped with a multispectral sensor and GPS positioning system, enabling it to conduct high-altitude reconnaissance of the rescue area, identify the optimal route, detect potential risks (such as landslides and snow accumulation), and transmit meteorological data (such as wind speed and temperature) in real time, providing decision support for the rescue platform. Furthermore, through a precision-controlled suspension mechanism, the drone can carry up to 5 kg of medical supplies (such as first-aid kits and altitude sickness medication), achieving hovering delivery in complex terrain and reducing the risks associated with manual transport. Considering that some areas in high-altitude power grid engineering projects (such as along high-voltage transmission lines) are uninhabited or have disrupted transportation, making emergency rescue difficult, this system can be used in case of emergencies at the engineering site. The system first uses drones to deliver medication, prioritizing the initial stabilization of power grid workers before ambulances transfer them for further treatment. This "air-ground" collaborative rescue process is particularly suitable for scenarios such as power transmission line maintenance and substation emergencies. Simultaneously, leveraging anti-interference communication technology, drones can act as mobile relay stations, maintaining continuous communication with the rescue platform and command center, transmitting patient vital signs data and on-site video, ensuring the accurate execution of rescue orders. This effectively solves the problem of ambulances being unable to reach the scene in high-altitude areas in a timely manner. By intervening with drones first, it compensates for transportation limitations and improves rescue response speed, coverage, and overall reliability.

[0051] Furthermore, the exhaust fan 110, fresh air frame 210, blades, opening and closing components for controlling the opening and closing of the blades, exhaust fan, ultraviolet disinfection lamp, and air purification layer 220 in this application are all referenced from an ambulance with negative pressure regulation function in patent number CN114343986B, and belong to the prior art. Their specific structures and working principles have been described in detail in the cited patent, so this application will not elaborate further.

[0052] In actual operation, the steps of this embodiment are as follows: Step 1: The exhaust fan 110 is started to draw air from the inside of the ambulance body 100, creating a basic negative pressure environment inside the vehicle; multiple air intake units 200 are activated simultaneously, and the fresh air frames 210 distributed around the side wall of the vehicle open their flaps (controlled by the opening and closing components), allowing outside air to enter the system through the ventilation holes 211. Step 2: The air entering the fresh air frame 210 is initially disinfected by ultraviolet disinfection lamps, and then passes through the air purification layer 220 (including an activated carbon adsorption layer and a HEPA filter) to remove particulate pollutants. The purified air enters the tree-shaped air duct 230, and is distributed to each branch duct 232 through the main pipe 231. The branch ducts 232 are connected to the main pipe 231 through connecting pipes to form a multi-stage airflow path. When the external wind pressure is strong (such as gusts at high altitudes), the middle part of the main pipe 231 expands under the impact of the airflow, forming a "bladder-like buffer section". When the airflow weakens, it elastically contracts, releasing the stored energy and smoothing the airflow fluctuations. Step 3: Sensors evenly distributed on the inner sidewalls of the vehicle monitor the negative pressure status of each area in real time, and are calibrated for high-altitude low-pressure environments to accurately detect minute pressure difference changes; if an abnormal negative pressure occurs in a certain area, the sensor transmits the pressure data to the external control system, which analyzes the data and locates the leak point or area with insufficient negative pressure. Step 4: After receiving the sensor signal, the control system triggers electromagnetic ring 260 and electromagnetic ring 252 in the area corresponding to the leak point. Electromagnetic ring 252 is energized and generates the same magnetism as magnetic ring 251, repelling magnetic ring 251 in the moving section 250, causing the moving section 250 to extend to the leak position. At the same time, electromagnetic ring 260 controls the expansion of the flexible section 241 in the middle of the fixed section 240 through the magnetic metal strip 242, adjusting the airflow output. After the moving section 250 extends, it concentrates the airflow to the leak point, forming a local airflow compensation zone. For leaks caused by sudden changes in air pressure at high altitudes, it quickly completes negative pressure compensation and prevents pathogens from leaking out. Step 5: After compensation is completed, the sensor detects that the negative pressure has returned to normal. The control system disconnects the electromagnetic ring current, the moving section 250 retracts, the flexible section 241 returns to its original state, and the airflow continues to circulate through the secondary channel 202 and the branch pipe 232. The opening area of ​​the secondary channel 202 increases from top to bottom, guiding the airflow from bottom to top to avoid the accumulation of pollutants under the vehicle. The exhaust fan 110 continuously extracts the air from the vehicle and discharges it outside the vehicle after disinfection.

[0053] The technical solutions described in the embodiments of this application have at least the following technical effects or advantages: This invention addresses the technical challenges of establishing negative pressure in low-pressure environments, uneven airflow distribution leading to leakage risks and pathogen isolation failure, decreased disinfection performance resulting in pollutant accumulation, increased risk of cross-infection, and delayed response lacking dynamic adaptability in existing technologies. It achieves the following technical effects: rapid establishment of negative pressure in low-pressure environments; uniform airflow distribution to reduce leakage risks and prevent pathogen isolation failure; improved disinfection performance to prevent pollutant accumulation; reduced risk of cross-infection; rapid response to enhance dynamic adaptability; and the integration of unmanned aerial vehicle (UAV) systems to enable remote environmental reconnaissance, emergency material delivery, and real-time communication and command functions, thereby improving the emergency rescue efficiency of power grid projects in high-altitude areas under extreme environments.

The emergency rescue platform for engineering operations in plateau areas as described in claim 1, characterized in that, The two air ducts (230) on the front and rear side walls and the inner sides of the left and right side walls of the ambulance body (100) are arranged in an alternating manner to increase the negative pressure convection inside the vehicle, so that the overall negative pressure inside tends to be stable.

4. The emergency rescue platform for engineering operations in plateau areas as described in claim 3, characterized in that, The middle section of the main pipe (231) is made of a flexible and highly elastic material. When the incoming external wind is strong, the middle section of the main pipe (231) expands due to the influx of airflow, forming a "bladder-type buffer section" to achieve a smooth transition of airflow.

5. The emergency rescue platform for engineering operations in plateau areas as described in claim 3, characterized in that, The ambulance body (100) has multiple channels inside its side wall for placing air ducts (230). The channels are sealed to the fresh air frame (210). Each channel includes a main channel (201) and multiple secondary channels (202). The main channel (201) corresponds to the main pipe (231) one by one, and the secondary channels (202) correspond to the branch pipes (232) one by one.

6. The emergency rescue platform for engineering operations in plateau areas as described in claim 5, characterized in that, The opening area of ​​each set of secondary channels (202) and its corresponding branch pipes (232) increases from top to bottom, so as to ensure that the airflow inside the vehicle gathers from all sides to the inside under the negative pressure of the exhaust fan (110), and is completely extracted from bottom to top by the exhaust fan (110) after disinfection, to prevent leakage.

7. The emergency rescue platform for engineering operations in plateau areas as described in claim 6, characterized in that, The branch pipe (232) is provided with two sections, namely a fixed section (240) and a movable section (250). The fixed section (240) is fixed in the sub-channel (202) by a mounting base, and the movable section (250) is slidably connected to the end of the fixed section (240); The moving section (250) is a multi-stage telescopic structure. A magnetic ring (251) is fixed in the first-stage telescopic section away from the fixed section (240). An electromagnetic ring (252) is fixed inside the fixed section (240). The extension and retraction of the moving section (250) are controlled by magnetic force, thereby accurately positioning and quickly compensating for negative pressure in a certain area inside the vehicle.

8. The emergency rescue platform for engineering operations in plateau areas as described in claim 7, characterized in that, The fixed section (240) has a flexible section (241) in the middle, which is made of flexible material and has a metal strip (242) on its outer side; an electromagnetic ring (260) is embedded in the sub-channel (202) at the position corresponding to the flexible section (241), and the expansion degree of the flexible section (241) is controlled by magnetic attraction.

9. The emergency rescue platform for engineering operations in plateau areas as described in claim 8, characterized in that, The inner wall of the ambulance body (100) is evenly arranged with multiple sensors for detecting the negative pressure state of a certain area inside the vehicle.

10. The emergency rescue platform for engineering operations in plateau areas as described in claim 9, characterized in that, The magnetic properties and on / off states of the electromagnetic ring one (260) and electromagnetic ring two (252) are controlled by an external control system. When a negative pressure abnormality or leakage occurs in a certain area of ​​the vehicle, the sensor in that area transmits the pressure information to the external control system. Then, the external control system controls the on / off state of electromagnetic ring one (260) and the magnetic properties and magnetic force of electromagnetic ring two (252) in that area, so that the moving section (250) of the corresponding branch pipe (232) quickly extends to the leakage position and controls the expansion state of the flexible section (241) to achieve rapid negative pressure compensation for a certain area in order to maintain the overall negative pressure state inside the vehicle.
