Description

Technical Field

[0001] This application relates to the technical field of rocket launch, and particularly to a general-purpose water spray noise reduction and gas supply system. Background Art

[0002] In the aerospace field, during the launch process of a launch vehicle, the jet flows of the first-stage and booster engines will generate aerodynamic noise of over 170 dB. This high-intensity noise poses a serious threat to the rocket structural components, sound-sensitive electrical components, as well as the environment and personnel safety around the launch site. In order to reduce the noise generated during launch and protect equipment and personnel, water spray noise reduction systems are widely used.

[0003] Although existing water spray noise reduction systems can reduce the noise generated during rocket launch to a certain extent, they generally have some limitations. For example, these systems often lack sufficient flexibility and versatility and are difficult to adapt to the specific requirements of different types of rockets. In addition, existing gas supply systems may not be able to ensure high-reliability unattended control capabilities and the consistency of pneumatic valve responses in harsh working environments. These limitations not only affect the water spray noise reduction effect but also increase the maintenance cost and operation risk. Summary of the Invention

[0004] The purpose of this application is to provide a general-purpose water spray noise reduction and gas supply system, which realizes dynamic balance supplementation during the rapid operation of pneumatic valves by introducing a buffer gas tank, effectively improving the consistency of pneumatic valve responses.

[0005] To achieve the above purpose, this application provides a general-purpose water spray noise reduction and gas supply system, including:

[0006] A gas distribution platform for filling the gas collection pipe and the buffer gas tank with gas;

[0007] A pipeline system communicating with the gas supply end of the gas distribution platform, and a gas collection pipe and a buffer gas tank are also connected to the pipeline system;

[0008] A gas collection pipe for supplying operating gas to the pneumatic valves on the water spray pipeline, and controlling the pneumatic valves through the operating gas;

[0009] A buffer gas tank located on the path between the gas supply end of the gas distribution platform and the gas inlet end of the gas collection pipe in the pipeline system.

[0010] In some embodiments, the gas distribution platform includes three operating gas supply branches connected in parallel between the gas inlet end and the gas supply end of the gas distribution platform.

[0011] In some embodiments, in the direction from the intake end to the supply end of the air distribution platform, a pressure reducer, a supply solenoid valve, and a one-way valve are sequentially arranged on the control air supply branch. Remote control is achieved through the supply solenoid valve, and a manual cut-off valve is also arranged on the control air supply branch.

[0012] In some embodiments, the first control air supply branch and the second control air supply branch are used to supply the control air after reducing its pressure to (1 - 2) MPa, and the third control air supply branch is used to supply the control air after reducing its pressure to (4 - 6) MPa.

[0013] During the control air supply process, initial rapid air replenishment is first carried out through the third control air supply branch, and then stable air replenishment is carried out through the first control air supply branch and the second control air supply branch. In the rocket launch process, the first control air supply branch and the second control air supply branch supply the control air after reducing its pressure to 0.8 MPa, and the supply solenoid valve is opened to implement real-time air replenishment in the unattended state.

[0014] In some embodiments, the general-purpose water spray noise reduction air supply system further includes:

[0015] An air distribution valve box, which is connected to the pipeline system. The air distribution valve box is located on the path between the buffer air tank and the intake end of the gas collecting pipe in the pipeline system.

[0016] In some embodiments, the general-purpose water spray noise reduction air supply system further includes:

[0017] A remote monitoring system, which is equipped with a pressure detector. The pressure measurement points of the remote monitoring system include the air source pressure, the pressure after the pressure reducer, the pressure of the gas collecting pipe, and the pressure of the gas collecting tank.

[0018] In some embodiments, the supply end of the gas collecting pipe supplies the control air in the form of a combination of a branch pipe and a flexible metal hose at the end of the branch pipe. The number of the branch pipes is multiple, and the multiple branch pipes are arranged in parallel on the gas collecting pipe. The diameter of the branch pipe is smaller than the diameter of the gas collecting pipe.

[0019] In some embodiments, the gas collecting pipe is installed in the vicinity of the water spray pipeline, and the gas collecting pipe is connected to the pneumatic valve in the vicinity.

[0020] In some embodiments, the air distribution platform is arranged in the front-end air distribution room, the gas collecting pipe is arranged on the support truss of the water spray pipeline, and the buffer air tank is arranged on both sides of the water spray pipeline.

[0021] In some embodiments, the capacity of the buffer air tank has a margin to meet the full-process operation requirements of the water spray pipeline.

[0022] Compared with the above background art, the general-purpose water spray noise reduction air supply system provided by the present application mainly includes a gas distribution table, a pipeline system, a gas collecting pipe, and a buffer gas tank. The gas distribution table is used to inflate the gas collecting pipe and the buffer gas tank; the pipeline system is communicated with the air supply end of the gas distribution table, and the gas collecting pipe and the buffer gas tank are also communicated with the pipeline system; the gas collecting pipe is used to supply control gas to the pneumatic valves on the water spray pipeline, and the pneumatic valves are controlled by the control gas; the buffer gas tank is located on the path between the air supply end of the gas distribution table and the air inlet end of the gas collecting pipe in the pipeline system.

[0023] During the rocket launch process, the control of pneumatic noise is a key technical challenge, especially when it is necessary to protect rocket structural components and sound-sensitive electrical components from damage. Although the existing water spray noise reduction systems can reduce noise, they often have problems such as inconsistent response of the air supply system and inflexible control, especially in harsh working environments. These problems may lead to inconsistent response of the pneumatic valves, affecting the effect of water spray noise reduction, and further affecting the safety and reliability of rocket launches.

[0024] To address these technical problems, the general-purpose water spray noise reduction air supply system provided by the present application realizes dynamic balance supplementation during the rapid operation of the pneumatic valves by introducing a buffer gas tank, effectively improving the consistency of the response of the pneumatic valves. This improvement is crucial for improving the performance of the entire water spray noise reduction system.

[0025] The gas distribution table inflates the gas collecting pipe and the buffer gas tank, ensuring sufficient gas supply for the system. The pipeline system connects the gas distribution table, the gas collecting pipe, and the buffer gas tank to form a continuous air supply path, which helps to ensure the continuity and stability of gas supply. The gas collecting pipe directly supplies control gas to the pneumatic valves on the water spray pipeline, and the opening and closing of the pneumatic valves are controlled by the control gas, thereby realizing the function of water spray noise reduction.

[0026] The introduction of the buffer gas tank is the key innovation point of this system. It is located on the path between the air supply end of the gas distribution table and the air inlet end of the gas collecting pipe. It can quickly supplement gas and balance the system pressure when the pneumatic valves operate rapidly. This dynamic balance supplementation mechanism enables the air supply pressure to be maintained stable even when the pneumatic valves operate rapidly and frequently, thereby ensuring the response speed and stability of the pneumatic valves and improving the response consistency of the entire system.

[0027] Combined with the above structural and process descriptions, it can be seen that the general-purpose water spray noise reduction air supply system has at least the following beneficial effects: The general-purpose water spray noise reduction air supply system realizes dynamic balance supplementation during the rapid operation of the pneumatic valves by introducing a buffer gas tank, effectively improving the consistency of the response of the pneumatic valves.

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0035] To enable those skilled in the art of this technology to better understand the solution of the present application, the following further detailed description of the present application will be made in combination with the drawings and specific embodiments.

[0036] Please refer to Figure 1 , Figure 1 Schematic diagram of the general-purpose water spray noise reduction air supply system provided by the embodiment of the present application.

[0037] In the first specific embodiment, the general-purpose water spray noise reduction air supply system provided by the implementation solution of the present application is applicable to a general-purpose automatic water spray noise reduction device; the air supply system mainly includes an air distribution station 1, a pipeline system 3, a collecting pipe 2, and a buffer gas tank 4. The air distribution station 1 is used to inflate the collecting pipe 2 and the buffer gas tank 4; the pipeline system 3 is communicated with the air supply end of the air distribution station 1, and the collecting pipe 2 and the buffer gas tank 4 are also communicated on the pipeline system 3; the collecting pipe 2 is used to supply operating air to the pneumatic valves on the water spray pipeline, and the pneumatic valves are controlled by the operating air; the buffer gas tank 4 is on the path between the air supply end of the air distribution station 1 and the intake end of the collecting pipe 2 in the pipeline system 3.

[0038] During the rocket launch process, the control of aerodynamic noise is a key technical challenge, especially when it is necessary to protect rocket structural components and sound-sensitive electrical components from damage. Although existing water injection noise reduction systems can reduce noise, they often have problems such as inconsistent response of the gas supply system and insufficient flexibility in control, especially in harsh working environments. These problems may lead to inconsistent response of pneumatic valves, affecting the effect of water injection noise reduction, and further affecting the safety and reliability of rocket launches.

[0039] To address these technical problems, the general-purpose water injection noise reduction gas supply system provided in this application realizes dynamic balance replenishment during the rapid operation of pneumatic valves by introducing a buffer gas tank 4, effectively improving the consistency of pneumatic valve response. This improvement is crucial for enhancing the performance of the entire water injection noise reduction system.

[0040] The gas distribution platform 1 fills the gas collecting pipe 2 and the buffer gas tank 4 with gas, ensuring sufficient gas supply for the system. The pipeline system 3 connects the gas distribution platform 1, the gas collecting pipe 2, and the buffer gas tank 4 to form a continuous gas supply path, which helps to ensure the continuity and stability of gas supply. The gas collecting pipe 2 directly supplies operating gas to the pneumatic valves on the water injection pipeline, and controls the opening and closing of the pneumatic valves through the operating gas, thereby realizing the function of water injection noise reduction.

[0041] The introduction of the buffer gas tank 4 is the key innovation of this system. It is located on the path between the gas supply end of the gas distribution platform 1 and the gas inlet end of the gas collecting pipe 2, and can quickly replenish gas and balance the system pressure when the pneumatic valve operates rapidly. This dynamic balance replenishment mechanism enables the gas supply pressure to be maintained stable even when the pneumatic valve operates rapidly and frequently, thereby ensuring the response speed and stability of the pneumatic valve, and improving the response consistency of the entire system.

[0042] Combined with the above structure and process description, it can be seen that the general-purpose water injection noise reduction gas supply system has at least the following beneficial effects: The general-purpose water injection noise reduction gas supply system realizes dynamic balance replenishment during the rapid operation of pneumatic valves by introducing a buffer gas tank 4, effectively improving the consistency of pneumatic valve response.

[0043] Please refer to Figure 2 , Figure 2 which is a schematic diagram of the gas distribution platform provided in the embodiment of this application.

[0044] In some embodiments, the gas distribution platform 1 includes three operating gas supply branches 11 connected in parallel between the gas inlet end and the gas supply end of the gas distribution platform 1.

[0045] In this embodiment, the gas distribution station 1 is designed with three parallel operating gas supply branches 11, which directly connect the inlet end and the supply end of the gas distribution station 1. This configuration allows the gas distribution station 1 to supply operating gas to different pneumatic devices or valves simultaneously, and each branch 11 can be independently controlled to adapt to different working pressure and flow requirements. Through this parallel design, the flexibility and efficiency of the gas supply system can be improved, ensuring that pneumatic valves can receive appropriate air pressure supply under different operating conditions, thereby achieving precise and reliable control. In addition, the design of multiple gas supply branches also helps to ensure that when one branch needs maintenance or fails, the other branches can still continue to supply gas to guarantee the normal operation of the system.

[0046] In some embodiments, in the direction from the inlet end to the supply end of the gas distribution station 1, a pressure reducer 6, a supply solenoid valve 7, and a check valve 8 are sequentially provided on the operating gas supply branch 11. Remote control is achieved through the supply solenoid valve 7, and a manual cut-off valve is also provided on the operating gas supply branch 11.

[0047] In this embodiment, on the operating gas supply branch 11 of the gas distribution station 1, a pressure reducer 6, a supply solenoid valve 7, and a check valve 8 are sequentially arranged in the direction from the inlet end to the supply end. This sequential arrangement of components is aimed at achieving precise control of gas pressure and management of gas flow direction.

[0048] The function of the pressure reducer 6 is to reduce the high-pressure gas to the required working pressure, ensuring that the operating air pressure supplied to the pneumatic valve is both safe and effective. The supply solenoid valve 7 after the pressure reducer 6 is used for remote control of gas supply. It can control the opening and closing of the valve according to the system's requirements or preset programs through electromagnetic signals, thereby achieving precise control of the pneumatic valve. This remote control method improves the automation level of the system, reduces manual intervention, and enhances the safety and convenience of operation.

[0049] The check valve 8 following the supply solenoid valve 7 functions to prevent gas backflow, ensuring that the gas can only flow unidirectionally, from the gas distribution station 1 to the pneumatic valve. This can avoid pressure fluctuations and damage to the pressure reducer 6 caused by gas backflow, and at the same time protect the stability of the gas supply system.

[0050] In addition, a manual cut-off valve is also provided on the operating gas supply branch 11 as a backup control means. When the automatic control system fails or needs maintenance, the gas supply can be cut off by manually operating the cut-off valve to ensure the safety of the system and facilitate maintenance. This design provides an additional safety guarantee, enabling the system to respond quickly in case of an emergency and preventing potential hazards.

[0051] During use, the gas distribution platform 1 is used to fill the gas collecting pipe 2 and the buffer gas tank 4 to ensure that the filling step is completed within the specified time; the gas source of the gas distribution platform 1 is connected from the high-pressure gas source pipe in the on-site gas distribution room, and three operating gas supply branches 11 are connected in parallel on the gas collecting and summarizing pipe of the gas distribution platform 1 for supply. Remote control and unattended gas supply after entering the launch process are realized through the gas supply solenoid valve 6 installed at the rear end of the operating gas supply branch 11. A pressure sensor and a safety valve are installed on the gas collecting and summarizing pipe of the gas distribution platform 1.

[0052] In some embodiments, the first operating gas supply branch 11 and the second operating gas supply branch 11 are used to reduce the operating gas pressure to (1 - 2) MPa for supply, and the third operating gas supply branch 11 is used to reduce the operating gas pressure to (4 - 6) MPa for supply;

[0053] During the operating gas supply process, initial rapid air replenishment is first carried out through the third operating gas supply branch 11, and then pressure stabilization air replenishment is carried out through the first operating gas supply branch 11 and the second operating gas supply branch 11; in the rocket launch process, the first operating gas supply branch 11 and the second operating gas supply branch 11 reduce the operating gas pressure to 0.8 MPa for supply, and the gas supply solenoid valve 7 is opened to implement real-time air replenishment in the unattended state.

[0054] In this embodiment, the system uses three different operating gas supply branches 11 to meet the air pressure requirements in different stages. Among them, the first and second operating gas supply branches 11 are responsible for supplying after reducing the air pressure to the range of 1 to 2 megapascals (MPa), while the third operating gas supply branch 11 is used to supply after reducing the air pressure to the range of 4 to 6 megapascals (MPa). Such a design allows the system to provide gases at different pressure levels according to different operating conditions to adapt to different working requirements.

[0055] In the initial stage of rocket launch, the third operating gas supply branch 11 is first used for rapid air replenishment to quickly reach the required high-pressure state, ensuring that the pneumatic valve can respond quickly and perform its functions. This step is crucial for quickly establishing the system pressure, especially at the critical moment of launch preparation.

[0056] Subsequently, the first and second operating gas supply branches 11 intervene to carry out pressure stabilization air replenishment through the supply of gas at 1 to 2 megapascals (MPa) to maintain the normal operation of the pneumatic valve, and the total filling time ≤ 1 h. This pressure stabilization air replenishment ensures the stable operation of the pneumatic valve during the launch process and prevents its performance from being affected by pressure fluctuations.

[0057] In the rocket launch process, to further ensure the stable operation of the pneumatic valves, the first and second operating gas supply branches 11 further reduce the air pressure to 0.8 megapascals (MPa) and supply it. At this time, the supply solenoid valve 7 is opened to achieve real-time air replenishment in the unattended state, ensuring that the pneumatic valves can receive continuous and stable air pressure supply throughout the launch process. This design improves the automation level of the system, reduces manual intervention, and also enhances the safety and reliability of the operation.

[0058] In some embodiments, the general-purpose water spray noise reduction gas supply system further includes:

[0059] A gas distribution valve box 5, which is connected to the pipeline system 3. The gas distribution valve box 5 is located on the path between the buffer gas tank 4 and the intake end of the gas collecting pipe 2 in the pipeline system 3.

[0060] In this embodiment, the general-purpose water spray noise reduction gas supply system further integrates the gas distribution valve box 5, which is directly connected to the pipeline system 3 and is specifically configured on the pipeline path between the buffer gas tank 4 and the intake end of the gas collecting pipe 2. Such a layout enables the gas distribution valve box 5 to receive the beneficial effects brought by the buffer gas tank 4 together with the gas collecting pipe 2.

[0061] The function of the gas distribution valve box 5 is to effectively supply operating gas to pneumatic valves such as the water supply valve, drain valve, and pre-filling valve on the water supply pipeline, ensuring that these pneumatic valves can receive stable and appropriate air pressure to perform their functions. The design of the gas distribution valve box 5 also particularly adopts a sealed explosion-proof structure, which is crucial for ensuring the safety of the entire gas supply system because it can prevent possible gas leakage and pressure accumulation, thereby reducing the explosion risk and enhancing the reliability of the system and the safety of operation.

[0062] In some embodiments, the general-purpose water spray noise reduction gas supply system further includes:

[0063] A remote monitoring system equipped with a pressure detector. The pressure measurement points of the remote monitoring system include the air source pressure, the pressure after the pressure reducer 6, the pressure of the gas collecting pipe 2, and the pressure of the gas collecting tank 4.

[0064] In this embodiment, the general-purpose water spray noise reduction gas supply system adds the function of a remote monitoring system, which is equipped with a pressure detector for real-time monitoring and recording of the pressure values at key positions in the system. Specifically, the pressure measurement points of the remote monitoring system cover the air source pressure, the pressure after the pressure reducer 6, the pressure of the gas collecting pipe 2, and the pressure of the gas collecting tank 4. The measurement data is remotely monitored throughout the process, and the data of the proximal control point and the distal control point are synchronized and interacted to ensure the reliability of the system operation and the convenience of daily maintenance.

[0065] Through these measurement points, the remote monitoring system can provide detailed information about the status of the gas supply system, enabling the operator to remotely monitor the system's operating conditions. This monitoring ability is crucial for ensuring the system operates in an optimal state as it allows for the timely detection of any potential pressure anomalies, which may be early signs of system failures or reduced efficiency.

[0066] For example, if the pressure after the pressure reducer 6 exceeds a predetermined range, it may indicate a problem with the pressure reducer 6 or the need for maintenance. Similarly, if the pressure readings of the gas collector pipe 2 or the gas storage tank 4 are abnormal, it may mean there is a leak or other issues. By remotely monitoring these key parameters, the system can intervene before the problem becomes severe, thereby reducing downtime and improving the reliability and safety of the system.

[0067] In some embodiments, the gas supply end of the gas collector pipe 2 supplies control gas in the form of a combination of branch pipes and flexible metal hoses at the ends of the branch pipes. The number of branch pipes is multiple, and the multiple branch pipes are arranged in parallel on the gas collector pipe 2. The diameter of the branch pipes is smaller than the diameter of the gas collector pipe 2.

[0068] In this embodiment, the multiple branch pipes are arranged in parallel on the gas collector pipe 2, and each branch pipe is connected to the gas collector pipe 2 to distribute gas to different pneumatic valves. The number of branch pipes is multiple, which can ensure that multiple pneumatic valves can receive control gas simultaneously, improving the gas supply efficiency and response speed of the system.

[0069] The diameter of the branch pipes is designed to be smaller than the diameter of the gas collector pipe 2. Such a design helps to reduce the pressure loss of the gas during transportation while maintaining the gas flow efficiency. The smaller diameter of the branch pipes can more precisely control the gas flow rate to each pneumatic valve, ensuring that each valve can obtain an appropriate amount of air pressure to perform its function.

[0070] The flexible metal hose at the end of the branch pipe combination provides additional flexibility and durability, especially in cases where vibrations and displacements may occur during the operation of the pneumatic valve. The metal hose can absorb these vibrations, reducing the impact on the entire system, and also reducing the risk of leakage at the connection caused by vibrations. This design improves the stability and safety of the system, ensuring long-term reliable operation.

[0071] With this configuration, the gas collector pipe 2 can effectively supply control gas to the pneumatic valves while ensuring the flexibility and durability of the system.

[0072] In some embodiments, the gas collector pipe 2 is installed in the vicinity of the water spray pipeline, and the gas collector pipe 2 is connected to the pneumatic valve in the vicinity.

[0073] In this embodiment, the collector pipe 2 is designed and installed in close proximity to the water spray pipeline, which means that the collector pipe 2 is arranged as close as possible to the water spray pipeline so as to be able to efficiently supply operating gas to the pneumatic valve. By this way of installation in close proximity, the transmission distance of the gas from the collector pipe 2 to the pneumatic valve can be reduced, thereby reducing the pressure loss and response time and improving the gas supply efficiency.

[0074] At the same time, the design of the close connection between the collector pipe 2 and the pneumatic valve means that the connection between the two is as short and direct as possible. This layout helps to ensure that the pneumatic valve can quickly receive the operating gas and achieve rapid and accurate control. In addition, reducing the length of the connecting pipeline also helps to reduce the complexity of the system and potential failure points, thereby improving the reliability of the entire system and the convenience of maintenance.

[0075] In some embodiments, the gas distribution platform 1 is arranged in the pre-positioned gas distribution room, the collector pipe 2 is arranged on the support truss of the water spray pipeline, and the buffer gas tank 4 is arranged on both sides of the water spray pipeline.

[0076] In this embodiment, the gas distribution platform 1 is arranged in the pre-positioned gas distribution room. Such a layout is conducive to the centralized management and control of gas distribution, and at the same time is convenient for operators to monitor and maintain. The pre-positioned gas distribution room, as a dedicated space, can provide the necessary protection and environmental control for the gas distribution platform 1 to ensure the stable operation of the gas supply system.

[0077] The collector pipe 2 is installed on the support truss of the water spray pipeline. This installation method enables the collector pipe 2 to maintain a close connection with the water spray pipeline, facilitating the direct supply of operating gas to the pneumatic valve. Such a layout of the collector pipe 2 also helps to reduce the pipeline length, reduce the pressure loss during gas transmission, and improve the response speed and efficiency of the system.

[0078] The buffer gas tank 4 is arranged on both sides of the water spray pipeline. This distributed layout can provide an even gas supply for the water spray pipeline to ensure that the pneumatic valve can obtain a stable air pressure at each part of the water spray pipeline. The installation position of the buffer gas tank 4 helps to quickly respond to the gas demand of the pneumatic valve and can also reduce the pressure fluctuations caused by uneven gas supply.

[0079] The pipeline system 3 adopts a distributed setting, which means that the design of the entire gas supply system allows gas supply at multiple key positions. This can improve the flexibility and reliability of the system. The distributed pipeline system 3 can ensure that when any part fails, other parts can still continue to work, thus ensuring the normal operation of the entire water spray noise reduction system. In addition, the distributed setting also helps to reduce the impact of a single failure point on the entire system and enhances the stability and safety of the system.

[0080] In some embodiments, the buffer gas tank 4 has a capacity margin to meet the full - process operation requirements of the water - spraying pipeline.

[0081] In this embodiment, the buffer gas tank 4 is designed to have a capacity exceeding the immediate demand, that is, there is a certain margin beyond the capacity required for normal operation. Such a design consideration is to ensure that during the entire operation of the water - spraying pipeline, regardless of the working conditions or demand changes, the buffer gas tank 4 can meet the gas supply requirements.

[0082] Having a capacity margin means that the buffer gas tank 4 can cope with the suddenly increased gas demand of the pneumatic valves, such as the rapid action or high - frequency operation of the pneumatic valves that may occur during rocket launch. This design provides additional buffering capacity to cope with possible gas supply fluctuations, ensuring that the pneumatic valves can obtain sufficient air pressure at any time to perform their functions.

[0083] In addition, the capacity margin of the buffer gas tank 4 helps to maintain the continuous operation of the water - spraying pipeline when there is a temporary failure in the gas supply system or unplanned maintenance is required, thereby improving the reliability and stability of the entire water - spraying noise - reduction device. In this way, the buffer gas tank 4 not only plays a role in normal operation but also provides necessary safety guarantees for the system in abnormal situations, ensuring that the full - process operation requirements of the water - spraying pipeline are met.

[0084] In some cases, when a carrier rocket is launched, the jet flows of the first - stage and booster engines will generate pneumatic noise above 170 dB, which will cause acoustic - induced vibration to the weak structural components on the rocket and the launch system, as well as to the sound - sensitive electrical components, resulting in destructive effects, and will also cause harm to the surrounding environment of the launch site and the test personnel.

[0085] As the first launch station in China that can accommodate more than ten types of rockets, the No. 2 launch station of the Hainan Commercial Space Launch Site is equipped with a water - spraying noise - reduction system that can be compatible with the water - spraying noise - reduction requirements of multiple types of rockets. The water - spraying noise - reduction system is set with two - stage water spraying. After the personnel evacuate during the launch process, the water - spraying noise - reduction system is operated unattended throughout the process by remotely controlling the pneumatic control valves. Therefore, a gas supply system for the water - spraying noise - reduction device is designed, which has the characteristics of high reliability of unattended control, high consistency of pneumatic valve response, and good convenience for daily maintenance and repair.

[0086] This application provides a general - purpose water - spraying noise - reduction gas supply system, which can remotely control the water - spraying noise - reduction device by remotely driving the pneumatic valves on the gas supply pipeline, and achieve automatic and intelligent water - spraying effects according to the water - spraying noise - reduction requirements of different commercial rockets, effectively saving labor costs and ensuring the safety of operators. The equipment status is monitored through the proximal control point and the distal control point, which is convenient for daily maintenance and repair.

[0087] The general-purpose water spray noise reduction air supply system can supply operating air as a power source to drive the piston in the cylinder of the remote control pneumatic control valve of the water spray system, enabling rapid supply of operating air for the pneumatic valve to achieve rapid response of the valve. After the personnel evacuate during the launch process, the system supplies air in an unattended mode. The system supplies air to the cylinder of the pneumatic valve through the method of buffer air balance. The capacity of the buffer air configured in the system has a certain margin to meet the operating requirements of the entire water spray system process. The control of the air supply system mainly adopts remote control, supplemented by proximal control in the control room. Both measurement and control methods can independently complete all process control actions such as opening and closing valves and starting and stopping pump groups, and have the ability of daily monitoring and maintenance.

[0088] The main operating air pipeline is distributed. The gas distribution station 1 is set in the front-end gas distribution room for filling the air supply system. The gas collecting pipe 2 is set on the support truss of the water pipeline. Small-diameter pipelines are connected to the gas collecting pipe 2 to quickly supply operating air to the pneumatic valves on the water spray pipeline in the short range. The pipeline system 3 is used for connecting the gas distribution station 1 with the gas collecting pipe 2 and between the gas collecting pipe 2 and the pneumatic device to provide a gas passage. The buffer gas tank 4 is set on both sides of the water pipeline for rapid buffer balance between the operation of the pneumatic valve and the operating air pipeline. The gas distribution valve box 5 supplies operating air to the pneumatic valves such as the water supply valve, drain valve, and pre-filling valve on the water supply pipeline. The gas collecting pipes 2 and the buffer gas tanks 4 in the system are connected by pipelines to ensure dynamic balance replenishment between each gas cylinder and gas collecting pipe during the rapid action of the valve, and improve the consistency of the response of the pneumatic valve.

[0089] It should be noted that many components mentioned in this application are common standard components or components known to those skilled in the art. Their structures and principles can be known by those skilled in the art through technical manuals or obtained through conventional experimental methods.

[0090] It should be noted that in this specification, relational terms such as first and second are only used to distinguish one entity from several other entities, and do not necessarily require or imply any actual relationship or order between these entities.

[0091] The above has introduced the general-purpose water spray noise reduction air supply system provided by this application in detail.
