A plurality of spray heads 8 are provided, and the plurality of spray heads 8 are respectively inclined and communicated with the two connecting pipes 7. The circulation assembly is arranged between one of the connecting pipes 7 and the collection pool 1;

[0046] Among them, the liquid level electronic float gauge 2 can detect and analyze underwater data through integrated sensors and electronic devices. The main components include sensors, transmitters and receivers. The sensors are responsible for detecting underwater temperature, humidity, water flow and other parameters, and transmitting these data to the transmitter. The transmitter wirelessly transmits the data to the receiver, and the receiver converts the data into readable information and starts the water pump 13.

[0047] Refer to Figure 1 and Figure 3, the spraying assembly includes a mounting base, a mounting box 9, an electric cylinder 10, a lifting frame 11 and a lifting plate 12. There are two mounting bases, and the two mounting bases are symmetrically arranged on both sides of the collection pool 1. The mounting box 9 is fixedly connected to each mounting base. The electric cylinder 10 is installed in each mounting box 9. The lifting frame 11 is fixedly connected to the output end of each electric cylinder 10. There are two lifting plates 12, and the two lifting plates 12 are symmetrically connected to each lifting frame 11. A groove matching the support pipe 6 is formed on the lifting plate 12. A plurality of lifting cylinders 21 are fixedly connected to the top end of the collection pool 1. A lifting rod 22 is slidably connected through each of the plurality of lifting cylinders 21. The plurality of lifting rods 22 are respectively fixedly connected to the plurality of lifting plates 12. Through the cooperation of the lifting cylinder 21 and the lifting rod 22, the lifting plate 12 can be stably supported during the movement of the lifting plate 12, so as to smoothly move the two support pipes 6;

[0048] The mounting base includes a mounting rod 17 and a mounting block 18. There are two mounting rods 17, and the two mounting rods 17 are symmetrically connected to the collection pool 1.

[0049] Starting the two electric cylinders 10 simultaneously can make the two electric cylinders 10 push the two lifting frames 11 at the same time, so as to make the plurality of lifting plates 12 drive the two support pipes 6 to move at the same time, so that the two connecting pipes 7 can drive the plurality of spray heads 8 to move, and the spraying range of the spray heads 8 can be adjusted.

[0050] Reference Figure 4 , the circulation assembly includes a water pump 13, a water outlet pipe 14 and a circulation pipe 15. The water pump 13 is installed on the outer side wall of the collection pool 1, and the water inlet end of the water pump 13 is connected to the collection pool 1 through penetration. The water outlet pipe 14 is communicated with the water outlet end of the water pump 13. The circulation pipe 15 is communicated with the adjacent connecting pipe 7, and a telescopic pipe 16 is communicated between the circulation pipe 15 and the water outlet pipe 14. The telescopic pipe 16 will expand or contract as the circulation pipe 15 moves;

[0051] When the liquid level electronic float 2 senses that the liquid level in the collection pool 1 reaches the appropriate liquid level range, it will send an electrical signal to start the water pump 13 after being converted by the sensor, so that the water in the collection pool 1 can enter the adjacent connecting pipe 7 through the water outlet pipe 14, the telescopic pipe 16 and the circulation pipe 15, so as to recycle the water resources.

[0052] Reference Figure 1 And Figure 4, another connecting pipe 7 is connected to a water inlet pipe 19, a spray automatic control valve 20 is arranged on the water inlet pipe 19, and an elastic pipe is connected to the water inlet pipe 19. The elastic pipe will expand or contract along with the movement of the water inlet pipe 19;

[0053] One side of the elastic pipe can be connected to a water supply pipe. When the pressure radar sensor 5 detects that the liquid nitrogen tank body is overpressured, it will send an electrical signal to the spray automatic control valve 20 through the background, and open the spray automatic control valve 20, so that water resources can enter the adjacent connecting pipe 7 through the elastic pipe and the water inlet pipe 19, so that the liquid ammonia tank body 4 can be sprayed all-round through a plurality of spray heads 8. After the pressure reduction requirement is met, the spray automatic control valve 20 can be automatically closed.

[0054] In summary, when the pressure radar sensor 5 detects that the liquid nitrogen tank body is overpressured during the use of the liquid ammonia tank automatic pressure reduction device, it will send an electrical signal to open the spray automatic control valve 20, so that water resources pass through the elastic pipe, the water inlet pipe 19, the support pipe 6 and the connecting pipe 7 and enter a plurality of spray heads 8, so that a plurality of spray heads 8 can spray and cool down the liquid ammonia tank, and at the same time, two electric cylinders 10 drive two lifting frames 11 and a plurality of lifting plates 12 to move simultaneously, so as to lift the two support pipes 6 and the two connecting pipes 7, so that the spraying range of a plurality of spray heads 8 can be adjusted, and then it is convenient to spray and reduce the pressure of the liquid ammonia tank all-round;

[0055] During the pressure reduction process, the sprayed water will enter the collection pool 1 for collection. When the liquid level electronic float 2 senses that the water level in the collection pool 1 reaches the appropriate liquid level range, it will send an electrical signal to start the water pump 13 through the sensor conversion, so that the water in the collection pool 1 passes through the water outlet pipe 14, the telescopic pipe 16 and the circulation pipe 15 and enters the adjacent connecting pipe 7 again, so that the water resources can be recycled.
