[0002] In deep-sea exploration and research, sound source equipment is one of the indispensable key tools. By transmitting and receiving sound waves, this type of equipment can accurately detect the seabed topography, resource distribution and environmental parameters. However, the extreme high pressure conditions in the deep-sea environment pose a severe challenge to the operation of sound source equipment. Since the seawater pressure rises sharply with increasing depth, if the pressure inside and outside the equipment cannot be effectively balanced, it will cause serious structural deformation or even damage, which will affect the normal operation and service life of the equipment.

[0003] Currently, traditional methods mostly rely on manual adjustment or simple mechanical pressure balancing devices, but these methods have limitations such as slow response speed, low adjustment accuracy, and inability to adapt to rapidly changing pressure conditions in real time.

[0004] Therefore, the applicant proposes a method and system for balancing the internal and external pressures of deep-sea sound source equipment. Summary of the invention

Compare the pressure difference obtained in step S2 with the balance parameters preset in step S1, wherein the balance parameters include at least: the maximum allowable pressure difference, the minimum pressure difference and the target pressure range; S4. According to the comparison result of step S3, a pressure adjustment instruction is generated and sent to the corresponding actuator; S5. The internal and external pressure balance system increases or decreases the amount of gas inside the device through the adjustment command sent in step S4; Among them, the step S5 of increasing or decreasing the amount of gas inside the equipment is specifically as follows: when the pressure difference is higher than the maximum allowable pressure difference and the target pressure range, the pressure relief valve in the internal and external pressure balance system is opened; when the pressure difference is lower than the minimum allowable pressure difference and the target pressure range, the balance in the internal and external pressure balance system is opened; when the pressure difference is within the target pressure range, the balance valve and the pressure relief valve of the balance system are reset.

[0007] Preferably, the pressure adjustment instruction generated in step S4 according to the comparison result of step S3 comprises the following steps: S4-1. The pressure sensor continuously collects pressure data of the internal and external environment of the deep-sea sound source device according to a preset time interval; S4-2. Calculate the difference between the internal pressure data of the device and the external environment pressure data obtained in step S4-1; S4-3. Compare the pressure difference value obtained in step S4-2 with the maximum allowable pressure difference, the minimum allowable pressure difference and the target pressure range preset in step S1.

[0009] Preferably, the method further includes: obtaining the alarm parameter in step S1, and when the pressure sensor detects that the pressure difference exceeds a safe range, determining whether it is necessary to issue an alarm signal according to the alarm parameter.

[0010] Preferably, when the alarm signal is issued, the detection process of the internal and external pressure balance system includes the following steps: a. automatically obtaining the water temperature reading through the temperature sensor in the internal and external pressure balance system; b. Compare the obtained water temperature reading with the preset safe temperature range; c. When the water temperature reading exceeds the preset basic water temperature range, the water temperature is regulated by the temperature control system in the internal and external pressure balance system; d. The recorded water temperature data and timestamp are transmitted to the control system; When the water temperature is within the preset basic water temperature range, the water level and internal and external pressure difference are further detected through the internal and external pressure balance system.

[0011] Preferably, the basic water temperature ranges from 5°C to 55°C.

[0012] To achieve the above-mentioned objectives, the present application also provides an automatic internal and external pressure balancing system for deep-sea sound source equipment, including: a pressurization system, an air storage system, a pressure relief system, a control system, a balancing system and an adjustment feedback system.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0023] See also Figure 1 , a method for solving the internal and external pressure balance of deep-sea sound source equipment, comprising the following steps: S1. Pre-set the basic parameters of the internal and external pressure balance system, the basic parameters include at least: inflation parameters, balance parameters and alarm parameters; S2. Start the internal and external pressure balance system and monitor the pressure difference between the internal and external environment of the deep-sea sound source equipment in real time through the pressure sensor; S3. Compare the pressure difference obtained in step S2 with the balance parameters preset in step S1; S4. According to the comparison result of step S3, a pressure adjustment instruction is generated and sent to the corresponding actuator; S5. The internal and external pressure balance system increases or decreases the amount of gas inside the device through the adjustment instruction sent in step S4.

[0024] In this embodiment, the pressure difference between the inside and outside of the equipment is monitored in real time by a pressure sensor, and inflation or exhaust is automatically adjusted according to the preset balance parameters to ensure that the pressure inside and outside the equipment is always kept within a safe range, thereby effectively responding to the rapidly changing pressure conditions in the deep-sea environment and ensuring the stable operation of the equipment. At the same time, the pre-setting of basic parameters and the real-time monitoring mechanism enable the system to respond quickly to pressure changes, avoid equipment damage or performance degradation due to excessive pressure differences, and improve the reliability and stability of the equipment. And by setting alarm parameters, when the pressure difference exceeds the safe range, the system will automatically send an alarm signal to prompt the operator to check and intervene, effectively preventing potential safety hazards.

[0025] Furthermore, if the pressure difference is within the preset balance parameter range, the pressure adjustment instruction is generated to maintain the current state and continuously monitor the pressure difference; if the pressure difference exceeds the balance parameter range, the control unit calculates the required inflation or exhaust volume based on the inflation parameters, and sends a pressure adjustment instruction to control the corresponding actuator to perform corresponding operations.

[0026] In one embodiment, the balance parameters include at least: a maximum allowable pressure difference, a minimum pressure difference, and a target pressure range.

[0027] In this embodiment, the maximum allowable pressure difference is the maximum value of the internal and external pressure difference that the device can withstand. When the actual pressure difference exceeds this value, the system will consider the device to be in a dangerous state and needs to take immediate measures to adjust or issue an alarm signal. The minimum allowable pressure difference is the minimum value of the internal and external pressure difference that the device can withstand. When the actual pressure difference is lower than this value, the system will also consider the device to be in an abnormal state and need to make corresponding adjustments. The target pressure range is an ideal pressure range, and the device is considered to be the safest and most efficient when operating within this range.

[0028] Furthermore, by controlling the pressure difference between the set maximum and minimum values, the system instability caused by excessive pressure fluctuations is avoided, ensuring the smooth operation of the system. At the same time, the setting of the minimum pressure difference prevents the equipment from operating at too high or too low pressure, thereby reducing the wear and failure rate of the equipment.

[0029] In one embodiment, the pressure adjustment instruction generated in step S4 according to the comparison result of step S3 is specifically: S4-1. The pressure sensor continuously collects pressure data of the internal and external environment of the deep-sea sound source device according to a pre-set time interval; S4-2. Calculate the difference between the internal pressure data of the device and the external environment pressure data obtained in step S4-1; S4-3. Compare the pressure difference value obtained in step S4-2 with the maximum allowable pressure difference, the minimum allowable pressure difference and the target pressure range preset in step S1.

[0030] Furthermore, the step S5 of increasing or decreasing the amount of gas inside the device is specifically as follows: when the pressure difference is higher than the maximum allowable pressure difference and the target pressure range, the pressure relief valve in the internal and external pressure balancing system is opened; when the pressure difference is lower than the minimum allowable pressure difference and the target pressure range, the balance in the internal and external pressure balancing system is opened; when the pressure difference is within the target pressure range, the balancing valve and the pressure relief valve of the balancing system are reset.

[0031] In one embodiment, the preset time interval in step S4-1 is 10 minutes.

[0032] In one embodiment, it also includes: Acquire the alarm parameter in step S1, and when the pressure sensor detects that the pressure difference exceeds the safety range, determine whether it is necessary to issue an alarm signal according to the alarm parameter; Specifically, first, the current pressure difference data is obtained from the pressure sensor; then, the read pressure difference is compared with the above alarm parameter (i.e., the preset safety range threshold); Furthermore, if the pressure difference exceeds the preset safety range threshold, it will be marked by the internal and external pressure balance system and the duration of the pressure difference exceeding the preset safety range threshold will be checked. When the pressure difference exceeds the threshold and meets the duration condition, the system will issue an alarm signal.

[0033] In this embodiment, it is possible to realize real-time monitoring of the pressure difference between the internal and external environments of the deep-sea sound source equipment, and to promptly issue an alarm signal when the pressure difference exceeds the safety range. Specifically, when the pressure sensor detects that the pressure difference exceeds the preset safety range threshold, the system will mark it and check whether the duration condition is met; if the duration condition is met, the system will issue an alarm signal to remind the operator to handle it, thereby effectively avoiding equipment damage or performance degradation caused by excessive or insufficient pressure difference. At the same time, the alarm parameters (i.e., the preset safety range threshold) and duration conditions and other parameters can also be adjusted according to actual needs to meet the needs of different scenarios.

[0034] In one embodiment, when the alarm signal is issued, the detection steps of the internal and external pressure balance system are specifically: a. automatically obtaining the water temperature reading through the temperature sensor in the internal and external pressure balance system; b. Compare the obtained water temperature reading with the preset safe temperature range; c. When the water temperature reading exceeds the preset basic water temperature range, the water temperature is regulated by the temperature control system in the internal and external pressure balance system; d. The recorded water temperature data and timestamp are transmitted to the control system; e. When the water temperature is within the preset basic water temperature range, the water level and the internal and external pressure difference are further detected through the internal and external pressure balance system.

[0035] In this embodiment, the water temperature reading can be obtained in real time and automatically adjusted according to the preset safe temperature range. When the water temperature exceeds the safe range, the temperature control system will automatically start to ensure that the water temperature remains at a safe level. At the same time, each water temperature reading and the corresponding timestamp are recorded and transmitted to the control system for further analysis and processing to identify potential problems or trends. For example, by analyzing historical data, it can be found that the water temperature fluctuates greatly in certain specific time periods, so that corresponding measures can be taken to adjust it.

[0036] In addition, the water level and the internal and external pressure difference can be further detected, so as to more comprehensively evaluate the operating status of the system and ensure that all parameters are within the normal range. For example, when the water level is too high or too low, the system can issue an alarm and take corresponding measures to adjust the water level. And it can effectively avoid system failures caused by abnormal single parameters. For example, when the water temperature exceeds the safe range, if it is not adjusted in time, it may cause the equipment to overheat or even be damaged. The automatic control function of this system can effectively prevent such situations from happening.

[0037] In one embodiment, the basic water temperature range is 5°C-55°C. Specifically, when the water temperature is lower than 5°C, the device may face the risk of freezing, and when it is higher than 55°C, the device may overheat, resulting in performance degradation or even damage. Therefore, setting the safe temperature range between 5°C-55°C can ensure that the device operates normally under appropriate temperature conditions.

The pressure relief system is connected to the boosting system, the gas storage system and the regulating feedback system through two solenoid valves. The regulating feedback system transmits real-time internal air pressure and external water pressure readings through a pressure transmitter installed on the device, and synchronously obtains the temperature of the boosting system through the setting of a temperature sensor.
