[0026] The water-spraying pipeline 5 is connected to the main pipeline 3 through a protection water-spraying water supply pipeline 6, the water-spraying pipeline 5 is horizontally arranged on the upper part of the secondary water supply pipeline 4, after the rocket ignition signal is sent, the cooling water in the main pipeline 3 is delivered to the water-spraying pipeline 5 through the protection water-spraying water supply pipeline 6, the protection water-spraying is carried out through the water-spraying pipeline 5, the valve and other components on the secondary water supply pipeline 4 are protected, and the safety of the water-spraying noise reduction system is ensured.

[0027] In use, in the initial state, the main pipeline 3 is in the closed state, after the rocket ignition signal is sent, the main pipeline 3 is controlled to be opened, under the action of the pressure of the main pipeline 3, the water accumulator 1 sprays cooling water to the launching platform through the secondary nozzle 2, the cooling water cools the high-temperature and high-pressure gas flow generated during the launching of the rocket, the water vapor molecules of the gasified water block the propagation of the noise, so that the purpose of noise reduction is achieved, at the same time, the main pipeline 3 supplies water to the water spraying pipeline 5 through the protective water spraying supply pipeline 6, the water spraying pipeline 5 sprays water to protect the water spraying noise reduction system, and the valve and other components on the secondary water supply pipeline 4 are protected, while the water spraying noise reduction system reduces the temperature and noise during the launching of the rocket, the water spraying noise reduction system can be protected, the safety of the water spraying noise reduction system is ensured, and the service life of the water spraying noise reduction system is prolonged.

[0028] In one embodiment of the utility model, the lower part of the secondary water supply pipeline 4 is equipped with a first control valve 401 and a first valve actuator 402, the first control valve 401 can control the on-off of the secondary water supply pipeline 4, and the first valve actuator 402 can control the opening of the first control valve 401, both the first control valve 401 and the first valve actuator 402 are arranged below the water spraying pipeline 5, so as to facilitate manual control and maintenance by the staff.

[0029] In addition, a second control valve (not shown in the figure) is arranged on the main pipeline 3, the second control valve can control the on-off of the main pipeline 3, wherein the second control valve adopts a pneumatic butterfly valve, the valve stem is driven by compressed air through the pneumatic butterfly valve, and the on-off can be completed by controlling the rotation of the butterfly plate by 90 degrees, so that the on-off of the main pipeline 3 can be accurately controlled.

[0031] At the same time, a flow sensor is arranged in the secondary water supply pipeline 4, the flow sensor is arranged below the water spraying pipeline 5, the water flow in the secondary water supply pipeline 4 can be monitored in real time through the flow sensor, so that the opening of the first control valve 401 is adjusted by the first valve actuator 402 according to the demand, so that the water accumulator 1 can continuously supply water to the secondary nozzle 2, and the continuous cooling and noise reduction effect of the water spraying noise reduction system is ensured.

Before the cooling water in the secondary water supply pipeline 4 enters the water accumulator 1, the filter can filter the impurities in the cooling water, so as to avoid that the impurities in the secondary water supply pipeline 4 or the main pipeline 3 are brought into the inside of the water accumulator 1 by the cooling water, thereby preventing the secondary nozzle 2 from being blocked due to long-term deposition of the impurities, and further ensuring that the cooling water in the water accumulator 1 can be smoothly sprayed from the secondary nozzle 2.

[0034] It should be noted that, to further ensure that the water accumulator 1 can continuously supply water to the secondary nozzle 2, a liquid level sensor is arranged in the inside of the water accumulator 1.

When the liquid level of the cooling water in the water accumulator 1 is higher than the water stop level line, the cooling water is stopped from being added to the water accumulator 1 through the water supply pipeline, so as to prevent the cooling water in the water accumulator 1 from overflowing.

[0035] In one embodiment of the utility model, in order to ensure that the secondary nozzle 2 normally sprays cooling water, first pressure sensor 8 can be selected to be arranged in main pipeline 3, the water pressure at the position of main pipeline 3 is monitored in real time through first pressure sensor 8, when the water pressure of main pipeline 3 is too low to normally supply water, timely maintenance and processing can be carried out, to ensure that main pipeline 3 normally supplies water to water accumulator 1. Second pressure sensor 9 is arranged in the inside of water accumulator 1, the water pressure in water accumulator 1 is monitored in real time through second pressure sensor 9, to ensure that water accumulator 1 can normally supply water to secondary nozzle 2. Third pressure sensor 10 is arranged in secondary nozzle 2, the water pressure at the position of secondary nozzle 2 is monitored in real time through third pressure sensor 10, when secondary nozzle 2 is blocked, timely discovery and processing can be carried out, to ensure that secondary nozzle 2 normally sprays cooling water.

[0036] The utility model discloses a working principle: initial state, first control valve 401, second control valve and third control valve 601 are all in the closed state, after the rocket ignition signal is sent, control opens first control valve 401 and second control valve, under the pressure of main pipeline 3, water accumulator 1 sprays cooling water to the launching platform through secondary nozzle 2, and the cooling water is cooled to the high-temperature high-pressure gas flow generated by the rocket, and the water vapor molecule is blocked to the propagation of noise, to achieve the purpose of noise reduction, simultaneously, second valve actuator 602 controls and opens third control valve 601, and main pipeline 3 supplies water to water spraying pipeline 5 through protective water spraying water supply pipeline 6, and water spraying pipeline 5 scatters water downward through protective water spraying nozzle 7, and the cooling water after spraying forms a downward water curtain, and the high-temperature high-pressure gas flow generated during the rocket launching is isolated, and the valve and other parts on secondary water supply pipeline 4 are protected, to prevent the water spraying noise reduction system from being ablated and blown.
