Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] The embodiment of the present invention provides a flexible connection system for ship module pipelines, which can solve the problem in the related art that module vibration will be transmitted to the outside through the condensate pipeline, affecting the safety of external equipment and the hull.

[0028] See also Figure 1 As shown, a flexible connection system for a marine module pipeline provided by an embodiment of the present invention may include: a steam boiler 1; a vibration isolation platform 2, wherein the vibration isolation platform 2 is arranged on one side of the steam boiler 1, and a posture adjustment device 3 is provided at the bottom of the vibration isolation platform 2, that is, the vibration isolation platform 2 is supported on the top of the posture adjustment device 3, and the vibration isolation platform 2 can be moved forward and backward, left and right, or up and down by the posture adjustment device 3 to adjust the posture of the vibration isolation platform 2, and a condenser 21 is provided in the vibration isolation platform 2, and the condenser 21 is connected to the steam boiler 1 through a condensate metal bellows 4, wherein the connection here can be understood as either a direct connection or an indirect connection; the vibration isolation platform 2 is provided with a steam turbine 22, and the steam turbine 22 is connected to the steam turbine 22 through a steam metal bellows 5. The steam boiler 1 is connected, and the connection here can also be understood as either a direct connection or an indirect connection. The adjacent sides of the condensate metal bellows 4 and the steam metal bellows 5 are provided with a deformation monitoring device 6, and the deformation monitoring device 6 can monitor the deformation of the condensate metal bellows 4 and the steam metal bellows 5 in the axial and radial directions respectively, and an alarm can be issued when the deformation exceeds a preset value; and a control system, which is connected to the deformation monitoring device 6, and the control system is connected to the posture adjustment device 3, and the control system can determine whether the condensate metal bellows 4 and the steam metal bellows 5 are in a safe state according to the data measured by the deformation monitoring device 6, and if they are in an unsafe state, the posture adjustment device 3 is controlled to electrically adjust the position of the vibration isolation platform 2.

[0029] In this embodiment, since the condenser 21 in the vibration isolation platform 2 is connected to the steam boiler 1 through the condensate metal bellows 4, and the steam turbine 22 is connected to the steam boiler 1 through the steam metal bellows 5, the condensate metal bellows 4 and the steam metal bellows 5 have certain flexibility, and the metal bellows can be stretched and compressed in the axial or radial direction to offset the transmitted vibration, which can supplement the displacement difference between the vibration isolation platform 2 and the steam boiler 1 under different working conditions and vibration conditions, and can avoid the vibration of the vibration isolation platform 2 from being transmitted to the outside and ensure the safe operation of the module. In addition, the deformation monitoring device 6 can monitor in real time whether the condensate metal bellows 4 and the steam metal bellows 5 are in a safe state. When the metal bellows are stretched too much in the axial or radial direction and are about to reach the maximum limit value, the deformation monitoring device 6 can issue an alarm and send a signal to the control system, so that the control system automatically controls the posture adjustment device 3, and then the posture adjustment device 3 drives the vibration isolation platform 2 to move in the horizontal plane or vertical direction, so that the flexible connection state between the vibration isolation platform 2 and the steam boiler 1 is restored to normal.

[0030] See also Figure 1 As shown, in some embodiments, a plurality of the posture adjustment devices 3 may be provided at the bottom of the vibration isolation platform 2, and the plurality of posture adjustment devices 3 may be arranged closely or at intervals, and the plurality of posture adjustment devices 3 may be arranged in sequence along the axial direction of the condensate metal bellows 4, and the plurality of posture adjustment devices 3 may be connected to the control system. Among them, each posture adjustment device 3 may be independent of each other, so that the control system may control any posture adjustment device 3 individually, for example, the height at which each posture adjustment device 3 is extended in the vertical direction may be controlled to be different, so that different parts of the vibration isolation platform 2 may achieve different heights, and different parts of the vibration isolation platform 2 may be controlled more flexibly.

[0031] Of course, in other embodiments, a posture adjustment device 3 may also be provided at the bottom of the vibration isolation platform 2 .

[0032] See also Figure 1 As shown, in some optional embodiments, the posture adjustment device 3 may include a horizontal driving mechanism and a vertical driving mechanism.

In this arrangement, the arithmetic mean of the three first dial gauges can be taken as the axial deformation of the metal bellows, and the second dial gauges at 90° to each other can be used to measure the unidirectional deformation of the metal bellows, and the deformation in the two directions are Δ1 and Δ2 respectively, and the radial deformation is:

[0035] See also Figure 1 As shown, in some embodiments, one end of the condensate metal bellows 4 is connected to the condenser 21 through the first pipeline 71, and the other end is connected to the steam boiler 1 through the second pipeline 72. The flexibility of the first pipeline 71 and the second pipeline 72 is less than the flexibility of the condensate metal bellows 4, that is, the first pipeline 71 and the second pipeline 72 are relatively hard. Through the arrangement of the first pipeline 71, the second pipeline 72 and the condensate metal bellows 4, the flexible connection between the condenser 21 and the steam boiler 1 is guaranteed, and the circulation of the material inside the pipeline and the connection between the pipeline and the condenser 21 and the steam boiler are guaranteed. 1; one end of the steam metal bellows 5 is connected to the steam turbine 22 through the third pipeline 73, and the other end is connected to the steam boiler 1 through the fourth pipeline 74. The flexibility of the third pipeline 73 and the fourth pipeline 74 is also less than the flexibility of the steam metal bellows 5, that is, the third pipeline 73 and the fourth pipeline 74 are relatively harder. Through the arrangement of the third pipe, the fourth pipeline 74 and the steam metal bellows 5, the flexible connection between the steam turbine 22 and the steam boiler 1 is guaranteed, and the circulation of the material inside the pipeline and the connection strength between the pipeline and the steam turbine 22 and the steam boiler 1 are guaranteed.

[0036] See also Figure 1As shown, in some embodiments, the first pipeline 71 and the second pipeline 72 are both provided with a stress strain gauge 81 at one end close to the condensate metal bellows 4, that is, the first pipeline 71 and the second pipeline 72 are both provided with a stress strain gauge 81, and the stress strain gauge 81 is arranged near the condensate metal bellows 4, the stress strain gauge 81 can monitor the stress of the first pipeline 71 and the second pipeline 72 in real time, and the second pipeline 72 is also provided with a pressure gauge 82 and a thermometer 83; the third pipeline 73 and the fourth pipeline 74 are both provided with a stress strain gauge 81 at the connection with the steam metal bellows 5, that is, the third pipeline 73 and the fourth pipeline 74 are also provided with a stress strain gauge 81, The stress strain gauge 81 is arranged near the steam metal bellows 5, and the stress strain gauge 81 can monitor the stress of the third pipeline 73 and the fourth pipeline 74 in real time, and the fourth pipeline 74 is also provided with a pressure gauge 82 and a thermometer 83; the stress strain gauge 81, the pressure gauge 82 and the thermometer 83 are all connected to the control system; the control system is also used to calculate the force conditions of the first pipeline 71, the second pipeline 72, the third pipeline 73 and the fourth pipeline 74 according to the data measured by the pressure gauge 82, the thermometer 83 and the stress strain gauge 81, and control the posture adjustment device 3 to electrically adjust the position of the vibration isolation platform 2 according to the calculation results.

[0037] In this embodiment, since stress strain gauges 81, pressure gauges 82 and thermometers 83 are provided on the pipeline, the stress condition of the pipeline can be monitored in real time, and whether the pipeline is in a safe state can be judged based on the calculation results. When a working condition with a safety risk is monitored, the pipeline can be restored to a normal state by adjusting the position state of the vibration isolation platform 2.

[0038] The stress strain gauges 81 provided on the first pipeline 71 and the second pipeline 72 may be normal temperature stress strain gauges 81 , and the stress strain gauges 81 provided on the third pipeline 73 and the fourth pipeline 74 may be high temperature stress strain gauges 81 .

[0039] In this embodiment, taking the adjustment of the system on the vibration isolation platform 2 from the operating point i to the operating point j as an example, the temperature, pressure, stress and strain measurement points on the pipeline collect various data at the operating point i and the operating point j in real time, and the system safety can be calculated in real time by the following formula. At the same time, the deformation monitoring device 6 monitors the deformation of the metal bellows in real time.

[0040] The change amplitude of the sum of primary and secondary stresses needs to meet certain rules, that is, when the system changes from one load state to another, the maximum change range of the sum of primary stress and secondary stress should meet the following formula:

[0041]

[0042] Where C1, C2, C3 are the stress indices of each load component under consideration; P0(i,j) is the pressure difference under load, MPa; M i (i, j) is the SRSS value (square root of the sum of squares) of the difference in the applied moment under the load state, N·mm; v is the Poisson's ratio; E is the elastic modulus, ×10 3 Mpa; α is the thermal expansion coefficient at room temperature, ×10 -6 / ℃; ΔT1(i,j) is the temperature between the pipe surface temperature T0 and the inner surface temperature T1 between loads i and j. i The temperature difference between the two, °C; E ab is the average elastic modulus of the material in the two discontinuous regions at room temperature, ×10 3 Mpa; T a (i,j),T b (i, j) is the average temperature change amplitude in area a and area b, ℃; S m is the basic allowable stress strength of the material at the design temperature, MPa; t is the nominal wall thickness of the pipe, mm; D0 is the outer diameter of the pipe, mm; I is the moment of inertia, mm ∧ 4.

[0043] If the temperature, pressure, stress-strain data of the operating point i and the operating point j are substituted into the above formula and the calculation result does not meet the requirements of the above formula, it means that the system is in an unsafe state. The vibration isolation platform 2 can be adjusted by the attitude adjustment device 3 until the above formula is met to restore the system to normal.

[0044] Further, the length of the first pipeline 71 is preferably smaller than the length of the second pipeline 72, and the length of the third pipeline 73 is preferably smaller than the length of the fourth pipeline 74. That is, the condensate metal bellows 4 and the steam metal bellows 5 are more inclined to the side close to the vibration isolation platform 2. Since the vibration isolation platform 2 will vibrate during operation, the second pipeline 72 and the fourth pipeline 74 with longer lengths are arranged on the side of the metal bellows away from the vibration isolation platform 2. The second pipeline 72 and the fourth pipeline 74 are separated from the vibration isolation platform 2 by metal bellows, and the vibration of the vibration isolation platform 2 is basically not transmitted to the second pipeline 72 and the fourth pipeline 74, thereby ensuring the accurate and normal operation of the thermometer 83 and the pressure gauge 82 on the second pipeline 72 and the fourth pipeline 74.

[0045] On the basis of the above technical solution, a generator 23 may be further provided on the vibration isolation platform 2, so that the generator 23, the steam turbine 22, the condenser 21 and the vibration isolation platform 2 form an integral module.

[0046] The embodiment of the present invention further provides a ship, which may include a hull and the above-mentioned flexible connection system of the ship module pipeline installed on the hull. The flexible connection system in this embodiment can adopt the flexible connection system of the ship module pipeline in any of the above-mentioned embodiments, which will not be repeated here.

[0047] The embodiment of the present invention further provides a method for dynamically adjusting the flexible connection system of the above-mentioned marine module pipeline, which comprises the following steps:

[0048] Step 1: Collect data measured by the deformation monitoring device 6.

[0049] Step 2: According to the data measured by the deformation monitoring device 6, it is determined whether the condensate metal bellows 4 and the steam metal bellows 5 are in a safe state. If they are in an unsafe state, the posture adjustment device 3 is controlled to electrically adjust the position of the vibration isolation platform 2.

[0050] Furthermore, the condensate metal bellows 4 and the steam metal bellows 5 are both connected to the steam boiler 1 through pipelines, and the dynamic adjustment method may also include: monitoring the stress, temperature and pressure of the pipeline; calculating the force condition of the pipeline according to the stress, temperature and pressure data, and controlling the attitude adjustment device 3 to electrically adjust the position of the vibration isolation platform 2 according to the calculation results.

[0051] Among them, stress strain gauges 81, thermometers 83 and pressure gauges 82 can be set on the pipeline to monitor the stress state of the pipeline in real time. For the pipeline on the condensate metal bellows 4, the pipeline can be set between the condensate metal bellows 4 and the steam boiler 1, or between the condensate metal bellows 4 and the condenser 21. Of course, pipelines can also be set between the condensate metal bellows 4 and the steam boiler 1, and between the condensate metal bellows 4 and the condenser 21; for the pipeline on the steam metal bellows 5, the pipeline can be set between the steam metal bellows 5 and the steam boiler 1, or between the steam metal bellows 5 and the steam turbine 22. Of course, pipelines can also be set between the steam metal bellows 5 and the steam boiler 1, and between the steam metal bellows 5 and the steam turbine 22. In this embodiment, the above-mentioned first pipeline 71, second pipeline 72, third pipeline 73 and fourth pipeline 74 are preferably used.

[0052] The embodiment of the present invention realizes the flexible connection of the internal and external pipelines of the vibration isolation platform 2 by setting a metal bellows on the pipelines entering and exiting the vibration isolation platform 2, and monitors and analyzes various parameters of the flexible connection pipeline in real time through the temperature, pressure, stress and strain measurement points set on the pipeline, calculates the real-time force distribution of the pipeline online, and judges the safety of the system based on the real-time calculation results. When a working condition with safety risks is monitored, the posture adjustment device 3 is adjusted to restore the installation state of the entire system to normal.
