[0015] The following is combined with Figure 1-5 The specific implementation modes of the present invention are further described in detail.

[0016] Embodiment 1, the technical solution is that, in the present application, the inlet end of the water supply pipe 28 is connected to the external water storage device (not shown in the present application), and the outlet end of the drain pipe 9 is connected to the inlet end of the water curtain spray assembly (not shown in the present application), so as to form a complete passage to achieve the purpose of releasing water to reduce dust. Under normal circumstances, during the use of the present application, the water of the external water storage device enters the water passage chamber 5 of the booster cylinder 1 through the water supply pipe 28 after the pressure pump oxygen pump is pressurized, and then flows from the tapered pipe 8 and the drain pipe 9 to the water curtain spray assembly, thereby forming a water curtain for dust reduction. Among them, the water can be initially pressurized when passing through the booster pump 29, and then fills the water passage chamber 5 and stabilizes the pressure, and then flows to the small diameter end through the large diameter end of the tapered pipe 8, which can further increase the pressure and ensure the spraying effect of the water curtain. Further, in order to ensure that the pressure is always stable at the corresponding level, the present application is also arranged with components such as a water pressure sensor 10, a controller 2, and a pressure regulating assembly 13.

[0017] Specifically, during the use of the present application, a water pressure sensor 10 for monitoring the water pressure inside the drain pipe 9 is installed. When the water pressure sensor 10 detects that the water pressure flowing through the drain pipe 9 is lower than the set value, the water pressure sensor 10 transmits this information to the controller 2, and the controller 2 controls the motor 19 of the drive assembly to work. The motor 19 will drive the drive rod 21 to rotate through its output shaft 20. When the drive rod 21 rotates, the plug rod 22 on it will rotate accordingly, and the plug rod 22 will drive the piston rod 15 to reciprocate along the axis of the adjustment cylinder 14 through the driven ring 23. The motor 19 is installed at the right end of the booster cylinder 1 through the support frame 18.

[0018] During the reciprocating movement of the piston rod 15: specifically, during the movement of the piston rod 15 to the left, the piston plate 16 on the piston rod 15 will move to the left accordingly. The movement of the piston plate 16 to the left will compress the air in the regulating cylinder 14 through the spring one-way valve 12 and the joint 11 and enter the pressure regulating chamber 6, thereby increasing the amount of gas in the pressure regulating chamber 6; during the movement of the piston rod 15 to the right, due to the setting of the spring one-way valve 12, the gas in the pressure regulating chamber 6 cannot flow out in the opposite direction through the joint 11 and the spring one-way valve 12. When the piston rod 15 moves to the right to the maximum stroke together with the piston plate 16, the air vent 17 completely leaks out, and external air can enter the regulating chamber 6. The piston rod 15 moves to the left again, and the piston plate 16 on the piston rod 15 will move to the left accordingly. The movement of the piston plate 16 to the left will compress the air in the regulating cylinder 14 through the spring one-way valve 12 and the joint 11 and enter the pressure regulating chamber 6, so that the gas in the pressure regulating chamber 6 continues to increase; with the reciprocating movement of the piston rod 15, the gas in the pressure regulating chamber 6 continues to increase, thereby increasing the air pressure in the pressure regulating chamber 6. The increase in the air pressure in the pressure regulating chamber 6 will force the rubber diaphragm 4 on the mounting ring 3 to expand toward the water chamber 5. As the diaphragm expands toward the water chamber 5, the space in the water chamber 5 will be compressed, thereby effectively increasing the water pressure therein. When the water pressure sensor 10 detects that the water pressure has increased to the set value, the water pressure sensor 10 transmits this information to the controller 2, and the controller 2 controls the motor 19 of the drive assembly to stop working, which means that the pressure regulating assembly 13 stops working.

[0019] Embodiment 2, on the basis of embodiment 1, a guide groove 26 is provided on the piston rod 15, and a guide block 27 slidably connected to the guide groove 26 is arranged on the adjusting cylinder 14, thereby limiting the piston rod 15 to slide only along the axial direction of the adjusting cylinder 14, avoiding its rotational dislocation and affecting the normal operation of the pressure regulating assembly 13.

[0020] Embodiment 3, based on embodiment 2, when the water pressure sensor 10 detects that the water pressure is too high than the set upper limit, the water pressure sensor 10 transmits this information to the controller 2, and the controller 2 starts the electromagnetic valve 25 to open, and then the gas in the pressure regulating chamber 6 is discharged through the exhaust pipe 24, so that the air pressure in the pressure regulating chamber 6 is reduced, and then the rubber diaphragm 4 will shrink and recover, and then the space of the water chamber 5 will increase, and the water pressure in the water chamber 5 will also decrease, so that the water pressure is restored to the normal set level. The present application is simple in structure, practical and convenient, and has strong practicality.
