[0029] Example:

[0030] like Figures 1 to 5As shown, the vacuum tube high-speed rail transit passenger and freight train system of the present invention includes a passage duct 1, in which a plunger-type carriage 1 is slidably fitted, and a first gas power device 2 and a second gas power device 3 are connected to one end of the passage duct 1, and a third gas power device 4 and a fourth gas power device 5 are connected to the other end. The vacuum tube high-speed rail transit passenger and freight train system of the present invention cooperates with the passage duct 1, the plunger-type carriage 13, the first gas power device 2, the second gas power device 3, the third gas power device 4 and the fourth gas power device 5. When in use, passengers and freight enter the plunger-type carriage 13 after entering the hatch on the side of the passage duct. After closing the hatch, the first gas power device 2 is started to blow air into the passage duct to generate positive pressure, and the third gas power device 4 is allowed to inhale air to generate negative pressure, so that the plunger-type carriage 13 moves forward in the passage duct 1; when braking or returning, the fourth gas power device 5 blows air into the passage duct 1 to generate positive pressure, and the second gas power device 3 is allowed to inhale air to generate negative pressure, so that the plunger-type carriage 13 brakes or runs in the reverse direction in the passage duct 1. The entire operation process is carried out in the passage duct 1, and no traffic accidents such as overturning and collision will occur, which greatly improves safety; at the same time, a higher operating speed can be achieved according to actual needs during the operation. It should be noted that the door of the plunger-type carriage 13 is in a sealed state after being closed. The oxygen required inside can be released using a pre-stored oxygen tank or produced using stored reaction raw materials. The exhaust gas generated inside can be discharged to the end where negative pressure is generated through a one-way valve. In addition, the plunger-type carriage 13 can also be provided with a mechanical braking mechanism, such as by providing a retractable brake pad to frictionally brake with the inner wall of the passage duct 1; a jet braking mechanism can also be used for braking, such as providing high-pressure gas nozzles at both ends of the plunger-type carriage 13, and reverse jetting to achieve braking.

[0031] As a preferred embodiment, the first gas power device 2 and the fourth gas power device 5 both include a positive pressure gas power duct, in which a turbofan engine 7 blowing air to the passage duct 1 is arranged, and a corresponding duct valve 6 is matched; the second gas power device 3 and the third gas power device 4 both include a negative pressure gas power duct, in which a turbofan engine 7 blowing air outward is arranged, and a corresponding duct valve 6 is matched. After such a design, when the plunger-type carriage 13 is running in the forward direction, the turbofan engine 7 in the first gas power device 2 and the third gas power device 4 is started, the corresponding duct valve 6 is opened, and the duct valves of the second gas power device 3 and the fourth gas power device 5 are closed; when braking or reverse running, the turbofan engine 7 in the first gas power device 2 and the third gas power device 4 is closed, the corresponding duct valve 6 is closed, and the duct valves of the second gas power device 3 and the fourth gas power device 5 are opened, and the corresponding turbofan engine 7 is started to brake (which can be matched with a mechanical braking mechanism or a jet braking mechanism).

[0032] As a preferred embodiment, a wind turbine 8 is provided at the end of the positive pressure gas power duct. After such a design, when the turbofan engine 7 in the positive pressure gas power duct is started, a large amount of air enters from the positive pressure gas power duct, and at this time, the wind turbine 8 can generate electricity and store energy by using the flow of air.

[0033] As a preferred embodiment, an air-cooled water tank 9 is provided in the positive-pressure gas duct and the negative-pressure gas duct. With such a design, the temperature in the positive-pressure gas duct and the negative-pressure gas duct can be reduced within a certain range, reducing high-temperature damage to the equipment. The section of the pipeline from the exhaust of the turbofan engine 7 to the passage duct 1 is made of high-temperature resistant material and is equipped with a water-cooled wall pipeline circulation system. The water-cooled wall pipeline circulation system is connected to the air-cooled water tank 9 circulation system, and hot water flows into the steam boiler, and cold water flows into the water-cooled wall and the air-cooled water tank 9.

[0034] As a preferred embodiment, two groups of exhaust gas power generation devices are also included, one group of exhaust gas power generation devices is connected to the first gas power device 2 and the second gas power device 3, and the other group of exhaust gas power generation devices is connected to the third gas power device 4 and the fourth gas power device 5. The exhaust gas power generation device includes a steam boiler 11 and a corresponding steam generator 12, and the air intake end of the steam boiler 11 is connected to the turbofan engine 7 through an air pipe. After such a design, the steam boiler 11 is connected to the turbofan engine 7 through the exhaust gas pipe 15, and the exhaust gas generated by it is collected. The steam boiler 11 is preheated to heat the steam boiler 11 to generate steam for power generation, thereby reducing heat waste. In addition, the high-pressure steam of the steam boiler 11 can also drive the air compressor to pump high-pressure gas to the gas storage tank, and the high-pressure gas flows into the turbofan engine 7, thereby improving the combustion efficiency of the turbofan engine 7. The outer top surface of the passage duct 1 can be equipped with solar panels for power generation.

[0035] As a preferred embodiment, an annular oil groove 14 is provided on the circumference of the plunger-type carriage 13, and an oil outlet hole and an oil return hole are provided on the annular oil groove 14. A corresponding lubricating oil tank 29 and an oil pump 30 are provided inside the plunger-type carriage 13, and both the lubricating oil tank 29 and the oil pump 30 are provided below the floor 28 of the plunger-type carriage 13; a sealing ring 16 is provided between the plunger-type carriage 13 and the passage duct 1. After such a design, the oil pump 30 is connected to the annular oil groove 14 through the pump oil pipe 31, and the annular oil groove 14 is connected to the lubricating oil tank 29 through the return oil pipe 32, so that the lubricating oil flows and lubricates in the annular oil groove 14 continuously. A plurality of oil storage pits 15 are also provided on the surface of the plunger-type carriage 13, and after the lubricating oil in the annular oil groove 14 overflows into the oil storage pits 15, it can be continuously and evenly lubricated.

[0036] It should be noted that a first magnet 32 ​​can be set at the bottom of the plunger-type carriage 13, and a second magnet 33 that repels the first magnet 32 ​​can be set at the bottom of the duct 1. The magnetic force has a certain lifting effect, which reduces the direct extrusion of the plunger-type carriage 13 on the surface of the duct 1, avoids deformation of the duct 1, and reduces maintenance costs.

[0037] As a preferred embodiment, hot and cold air circulation fans 17 are provided at both ends of the plunger-type carriage 13. The hot and cold air circulation fans 17 are equipped with corresponding circulation pipes and valves. When hot and cold air circulation is required, the corresponding valves can be opened to turn on the hot and cold air circulation fans 17.

[0038] It is worth noting that the plunger-type carriage 13 has cooling and heating air circulation fans at both ends, lighting devices and toilets inside, and lubricating oil tanks 29, oil pumps 30, pump oil pipes 31, and return oil pipes 32 at the bottom; there are also facilities such as water storage tanks, feces tanks, batteries, fire extinguishers, and emergency generators. A second magnet 33 is installed at the bottom of the entire passage duct 1, and a first magnet 32 ​​is installed at the bottom of the plunger-type carriage 13, which play a role of mutual repulsion. The magnetic force has a certain lifting effect, reducing the direct extrusion of the plunger-type carriage 13 on the surface of the passage duct 1, avoiding the deformation of the passage duct 1, and reducing maintenance costs. When the plunger-type carriage 13 needs to pass through a parking station, the first magnet 32 ​​at the bottom of the plunger-type carriage 13 attracts the electromagnet installed at the station of the passage duct 1, sucking the plunger-type carriage 13. The materials of the passage duct 1 and the plunger-type carriage 13 are made of hard materials with smooth surface, wear resistance, high and low temperature resistance, high and low pressure resistance, and small thermal expansion coefficient, such as tempered glass or polycarbonate and carbon fiber materials. The outside of the passage duct 1 is wrapped with an elliptical steel template or glass fiber reinforced plastic and fixed on a flat road surface. The turbofan engine 7 can use environmentally friendly fuels such as natural gas, methanol, liquefied gas, methane and coal gas.

[0039] As a preferred embodiment, a parking mechanism 19 cooperating with the plunger-type carriage 13 is provided at both ends of the passage duct 1. The parking mechanism 19 includes a central shaft 21, a bearing 22 is provided on the central shaft 21, a crossbar 23 and a sloping plate 24 are connected to the outer ring of the bearing 22, a limiting ball 25 is provided at the end of the crossbar 23, and a spring 26 connected to the top of the passage duct 1 is also provided on the crossbar 23; a limiting block 18 is provided at the end of the plunger-type carriage 13, and a groove 20 cooperating with the limiting ball 25 is provided on the limiting block 18. After such a design, when the plunger-type carriage 13 arrives, the limiting block 18 touches the sloping plate 24, driving the outer ring of the bearing 22 to rotate clockwise, pressing the crossbar 23 downward, so that the limiting ball 25 is stuck in the groove 20. When the plunger carriage 13 is ready to start, the turbofan engine 7 generates wind pressure to make the inclined plate 24 move upward under the wind force, driving the outer ring of the bearing to rotate counterclockwise, so that the cross bar 23 is lifted up, so that the limiting ball 25 is separated from the groove 20. It should be noted that the cross bar 23 can also be driven to rotate electrically to change the matching relationship between the limiting ball 25 and the groove 20.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
