[0048] Please refer to Figures 1 to 5. To achieve the above-mentioned purpose, the present invention provides a universal automatic water spray noise reduction system for water spray noise reduction during rocket ignition in a launch site, including a water supply system, a water spray system, an air supply system and a control system.

[0049] The water supply system includes a high-level water tank 100 capable of storing water, and a first water channel 200 and a second water channel 300 connected to the high-level water tank 100 .

[0050] Among them, the bottom of the water tank 100 is provided with a water outlet for liquid to flow into the first water channel 200 and the second water channel 300. The water outlet is provided with a guide plate for liquid diversion and a reinforcement ring connected to the guide plate. The guide plate and the reinforcement ring are used to ensure the uniformity of liquid flow at the bottom water outlet of the water tank 100 and prevent the generation of vertical eddy currents. A reinforcing rib plate is welded on the water outlet pipe below the water tank 100 to enhance the overall structural strength of the water tank 100, the first water channel 200 and the second water channel 300.

[0051] In addition, it also includes a water replenishment pipeline 900 connected to the first water channel 200 and the second water channel 300 to supply water to the water tank 100. The water supply source comes from the water pump room of the launch site. After the water is pressurized twice by the water pump, the water replenishment pipeline 900 passes through the first water channel 200 and the second water channel 300 through a bottom-up water replenishment method to achieve the filling of the first water channel 200 and the second water channel 300 and the high-level water tank 100; the water tank 100 is provided with a pressure sensor for detecting the pipeline pressure, as well as a continuous liquid level gauge and a point liquid level gauge for detecting the liquid level height, so as to judge the opening and closing of the water replenishment pipeline 900 when the water level reaches the preset position.

[0052] The water spray system includes a plurality of secondary water spray devices connected to the first water channel 200 or the second water channel 300 through a secondary pipeline 400, a plurality of primary pipelines led out from the first water channel 200 and the second water channel 300, and a primary water spray device connected to the primary pipeline.

Both the secondary pipeline 400 and the primary pipeline are provided with a manual valve 410 and a pneumatic valve 420 for adjusting the flow rate and for realizing on and off.

[0053] It should be noted that the first waterway 200 and the second waterway 300 are two large-diameter pipes coming out from the bottom of the high-level water tank 100. The first waterway 200 extends to the south side of the launching platform 560, and multiple primary pipes and secondary pipes 400 are led out from the first waterway 200; the second waterway 300 extends to the west and north sides of the launching platform 560, and multiple secondary pipes 400 are led out from the second waterway 300 on the west side, and multiple primary pipes and secondary pipes 400 are led out from the second waterway 300 on the north side.

A two-stage water spraying device is arranged around the launch pad 560 in the launch site, and a first-stage water spraying device is arranged inside the launch pad 560. The manual valve 410 is normally open, and the flow rate is adjusted by remotely controlling the opening degree of the pneumatic valve 420 through the control system. The opening time of the pneumatic valve 420 is controlled to adjust the water spraying amount. The first and second stage water spraying flows can be adjusted according to the water spraying and noise reduction requirements of different rockets. The water spraying on-off function can be realized when there is no one on site, thereby ensuring the safety of personnel during launch and saving personnel costs. At the same time, it can meet the water spraying and noise reduction requirements of different rocket models to improve the versatility of the water spraying and noise reduction system.

[0057] The secondary water spray device is configured as a first water spray component connected to the first water channel 200, and a second water spray component and a third water spray component connected to the second water channel 300. The first water spray component and the third water spray component are relatively arranged on both sides of the launch platform 560 in the first direction, and the second water spray component is located on one side of the launch platform 560 in the second direction; the first water spray component, the second water spray component and the third water spray component all include a water reservoir 540 connected to the secondary pipeline 400 and a first nozzle 550 arranged on the water reservoir 540.

The secondary pipeline 400 and the primary pipeline are both provided with a manual valve 410 and a pneumatic valve 420 for adjusting the flow rate and for realizing on-off. The on-off function of the short-range and long-range water spraying of the secondary water spray device is realized through remote control when there is no one on site. At the same time, the pneumatic valve 420 of the secondary pipeline 400 has a slow closing function, which plays a role in suppressing the destructive effect caused by excessive water hammer.

[0058] The primary pipeline is configured as a reserved primary water spray pipe 610 connected to the second water channel 300, and a movable platform primary water spray pipe 620 connected to the first water channel 200 and two fixed platform primary water spray pipes 630; the primary pipeline is divided into four routes, two (two routes) fixed platform primary water spray pipes 630 are used for the fixed launching platform 560, one movable platform primary water spray pipe 620 is used for the movable launching platform 560, and one reserved primary water spray pipe 610, wherein emergency fire fighting water spraying is realized through the reserved primary water spray pipe 610; the movable platform primary water spray pipe 620 extends to the inside of the launching platform 560 through a DN500 pipeline, and the movable platform primary water spray pipe 620 is provided with a plurality of reserved pipeline interfaces 621 of DN200 pipelines for docking with the launching movable platform, which is used for water spraying when the movable launching platform is subsequently used.

[0060] The fixed platform first-level water spray pipe 630 is a DN800 pipe, which is then converted to DN600 for connecting to the water outlet pipe 710. The two water outlet pipes 710 are two metal bellows on the east and west sides for liquid diversion. Multiple DN100 cylindrical second nozzles 720 are evenly distributed on the main pipe of the water outlet pipe 710. The second nozzle 720 is designed at a fixed angle downward. The total design flow rate of the second nozzle 720 is 6t / s, and the single flow rate is 3t / s.

[0061] All primary pipelines and all secondary pipelines 400 are provided with a discharge pipeline 440 and a pre-filling water circuit.

[0062] Among them, an internal leakage monitor 443 is provided on the leakage pipeline 440 on the secondary pipeline 400, which is used for internal leakage detection of the leakage manual valve 441 and the leakage pneumatic valve 442. The internal leakage monitor 443 is specifically a DN20 manual valve led out from the leakage pipeline 440, which is used for internal leakage detection of each valve on the pipeline.

[0063] The end of the secondary pipeline 400 is connected to the bottom of the water reservoir 540 through the hose 460. Specifically, a DN800 metal bellows is installed above the secondary pipeline 400, and the rear end of the metal hose 460 is connected to the bottom of the horizontally placed water reservoir 540. The connection of the metal hose 460 can facilitate the installation of each water spray branch pipeline and effectively reduce the impact vibration during water spraying.

[0064] In some embodiments, the air supply system includes a first air collecting pipe 810 corresponding to the first water spray assembly, a second air collecting pipe 820 corresponding to the second water spray assembly, and a third air collecting pipe 830 corresponding to the third water spray assembly.

The first-level water spray pipe 620 of the movable platform is connected to the reserved flange interface by the hose configured by the rocket according to the rocket water spray flow requirement to spray water so that the surface of the movable launch pad is soaked. The water in the first-level water spray pipe 630 of the fixed platform enters the water outlet pipeline 710 and is sprayed along the second nozzle 720. Then the rocket starts to rise and enters the second-level state. The control system controls the first-level water spray pipe 630 of the fixed platform to disconnect, and the control system controls the pneumatic valve 420 on the secondary pipeline 400 to open. After the water in the secondary pipeline 400 enters the water reservoir 540, it is sprayed toward the launch pad 560 through the first nozzle 550 to further reduce the noise during the rocket launch. Then, the water tank 100 is replenished with water through the water replenishment pipeline 900 for next use.
