The low-temperature high-pressure fluid can be quickly heated to be changed into gas flowing at high speed in the discharging process, and potential safety hazards are easy to occur. In particular, for fluids such as hydrogen, oxygen, etc. that are at risk of combustion explosion or are strongly oxidizing, the flow rate must be controlled more closely. In order to solve the problem that the high-speed flowing gas is difficult to discharge, a method of discharging high-altitude open space after natural evaporation is generally adopted in the prior art, and high requirements are placed on the caliber, the roughness of the inner surface and the discharge temperature of a pipeline. In the above discharge method, in order to reduce the flow rate, it is also necessary to enlarge the pipe diameter of the discharge pipe to reduce the gas flow rate so as to ensure that the discharge gas flow rate is within the allowable range. The cross section of the pipe body can be effectively improved by increasing the caliber of the pipeline, so that the flow speed of gas in the pipeline is reduced. Furthermore, in order to avoid the high-speed flowing gas from generating severe friction with the pipe wall, the roughness degree of the inner surface of the discharge pipe needs to be reduced, so that the danger caused by static electricity is reduced while the flow resistance is reduced. The discharge temperature is controlled to prevent harm such as impact caused by solid particles introduced by freezing of water vapor. In the prior art, the construction of the large-diameter pipeline, the temperature control work and the treatment and monitoring work of the roughness of the inner surface of the pipeline need to be finished at high altitude, so that the problem of high construction difficulty is solved. Moreover, the discharge pipeline also needs to meet the construction requirement of high support reaction force caused by high-pressure exhaust, and further brings greater construction difficulty for building a low-temperature high-pressure fluid discharge device at high altitude.

1. the invention provides a low-temperature high-pressure fluid discharge device, which comprises: the foundation is provided with a discharge cavity, and a fluid discharge pipeline extends into the discharge cavity and discharges fluid media to the discharge cavity; and the filling material is filled into the discharge cavity so as to tightly fix the fluid discharge pipeline. The invention adopts a sinking type discharging method to discharge low-temperature high-pressure fluid into the discharging cavity, and fills the discharging cavity by filling materials. Compared with the prior art, the construction of the low-temperature high-pressure fluid discharge device needs to be completed at high altitude, and the fluid discharge pipeline is buried in the foundation, so that the construction difficulty is effectively reduced. In addition, the filling material can be used for effectively positioning and fixing the fluid discharge pipeline, so that the problem that the fluid discharge pipeline is difficult to position and fix due to the fact that the fluid is high in speed in the low-temperature and high-pressure fluid discharge process is solved. Moreover, the filling material can also be used as a discharge receiving end of fluid sprayed out of the discharge pipeline, so that heat exchange can be effectively carried out with low-temperature high-pressure fluid, the problem that the low-temperature high-pressure fluid such as liquid hydrogen is insufficient in heat exchange due to too low temperature is avoided, and the influence on the surrounding environment in the discharge process of the low-temperature high-pressure fluid is reduced. In addition, the heat insulating material enables fluid in the low-temperature high-pressure discharge pipeline not to exchange heat with the outside in a large amount, so that the problem of overhigh flow speed caused by rapid increase of specific volume is solved. 2. According to the low-temperature high-pressure fluid discharge device provided by the invention, the cavity bottom of the discharge cavity is a slope extending towards the depth direction of the foundation; the fluid discharge pipeline is arranged on the slope, and the outlet end of the fluid discharge pipeline extends towards the depth direction of the foundation.

Because the low-temperature high-pressure fluid can be quickly vaporized at normal temperature and normal pressure in the transportation process, the risk of overpressure and high-speed flow can be brought due to the fact that the specific volume is quickly expanded due to the fact that the low-temperature fluid is quickly vaporized, the fluid discharge pipeline is gradually led into the underground with deeper depth through the slope, so that the filling materials can be gradually increased towards the outlet end of the fluid discharge pipeline, and the problem that the low-temperature high-pressure fluid in the fluid discharge pipeline is difficult to position and fix when the flow rate is faster and the pressure is higher is solved. And, the fluid discharge line is angled down making the spout more secure. Moreover, the slope can effectively lead the outlet of the fluid discharge pipeline to a deeper position, reduce the influence on the surrounding environment in the process of discharging low-temperature and high-pressure fluid and simultaneously reduce the influence caused by the fire problem that the relative friction force between the fluid and the pipe wall of the fluid discharge pipeline is large.
