The invention relates to a tool for gas tunnel transportation, and the equipment is used for passenger transportation, wherein the tool comprises:
With the development of cities, the pressure on urban traffic increases, and railways have become the main means of transportation in large and medium-sized cities. The car body quality of existing tunnel engineering trains is unreliable, and the traditional two-axle car has a large wheelbase and poor passing ability on curves. The gas tunnel of the invention utilizes the thrust of high-pressure gas and the differential pressure of high-pressure vacuum suction to provide power to the gas tunnel.
The technical problem to be solved by the invention is to divide the air tunnel into area A and area B by placing a cylinder 3 for transporting customers and a vacuum baffle or ring (with liquid nitrogen cooling system inside) 8 in the air tunnel with strong airtightness; air is filled into area A of the cylinder 3 in the sealed pipeline through the air compressor pump 4, and the air in area B is pumped out by the vacuum pump 5 to form the pressure difference in front of and on the back of the cylinder 3 to provide power.
When the back of the cylinder 3 is filled with high-pressure air and the air in the front is drawn out to form a vacuum, not only the air resistance in the front disappears, but also a huge pressure difference is formed to provide power to the cylinder 3.
The final speed can exceed 20000 km/h.
According to the invention, the starting sequence of the cylinder 3 operation in the air tunnel is:
When the passenger departs from area A to area B, the gas storage tank 1 in area A is inflated to increase the pressure when the passenger enters the inside of the cylinder 3 and takes a ride. The gas in area B is drawn out by the vacuum pump 5 to form a vacuum state. When passengers are ready, the stuck spring 6 and the valve of the gas storage tank 1 are released simultaneously; since the front is a vacuum state without air resistance, the cylinder 3 will run at super high speed to area B zone until hits the spring 6 in area B and stops. Passengers can be overwhelmed when the cylinder hits the spring quickly, so airbags are used in the interior of the passenger compartment as well as in the recliner. When the cylinder is approaching the end, pouring a small amount of pressure gas can make the cylinder stop softly, and since the cylinder is closed, it may cause hypoxia, so it is necessary to install an oxygen cylinder to supply oxygen. If the customer plans to go from area B to area A, the equipment can run in reverse.
If the vacuum pump 5 can't exhaust the excess air in the pipeline on time, it can be equipped with a big blower to assist it in vacuuming. In order to obtain the desired speed, the vacuum leakage rate of the pipeline must be small, and the goal can only be achieved if the air is not leaked.
The second scheme: if the friction force of the vacuum baffle plate 8 is too large, replace the vacuum pump 5 that generates the vacuum environment with a fan, which can reduce the frictional force of the cylinder 3 or produce no friction. But for option one, the speed will be slower.
The smaller the gas tunnel, the less material and energy used, so one row in the cylinder 3 is equipped with two horizontal seats (15). If there is one seat per row, the cylinder 3 can be smaller, but the length of the cylinder 3 may be too long.
According to the length of the air tunnel, the number of air compressor pumps 4 and vacuum pumps 5 will increase, and a larger gas storage tank 1 is also required.
