Description

TECHNICAL FIELD

[0001] The present application relates to the field of ship and ocean engineering technology, and in particular to a moon pool wave absorbing device. BACKGROUND

[0002] In the field of ocean engineering, in order to facilitate operation in harsh marine environment conditions, a moon pool system is provided in the interior of the ship body in most cases. Due to the heave and horizontal roll motion of the ship body, waves are induced in the moon pool, and when the waves impact the moon pool coaming, large surges are easily generated, thereby causing serious damage to the operation equipment in the moon pool area. The existing ocean engineering technology usually opens a large number of wave absorbing holes on the moon pool coaming. Although this scheme can play a wave absorbing role to a certain extent, the system wave absorbing capacity will decrease significantly when operating in high sea conditions, and the opening of the holes will also cause the ship body components to be directly exposed to the air and be eroded by sea wind and sea water, which easily causes the anticorrosive coating to fall off and the surface of the components to be corroded, thereby seriously weakening the local strength of the ship body and causing great safety hazards to the operation of the ocean engineering equipment.

[0010] The motor assembly is started when the pressure sensor detects that the real-time pressure on the moon pool wall reaches the first preset pressure value, so as to suck the gas in the vertical pipe.

[0011] The valve is opened when the pressure value at the valve reaches the second preset pressure value, so that the horizontal pipe is connected with the vertical pipe.

[0012] Optionally, each of the detection systems includes multiple pressure sensors, which are uniformly arranged, and the motor assembly connected with the pressure sensor is started when the real-time pressure detected by any one of the pressure sensors reaches the first preset pressure value.

[0021] The beneficial effects of the present invention include at least the following:

[0022] This invention provides a wave-damping device for a moon pool, installed in the upper wave zone of the moon pool enclosure wall, with wave-damping holes provided on the wall. The detection system includes a pressure sensor and a controller connected by a signal connection. The power system includes a starter, a power supply, and a motor assembly. The motor assembly is electrically connected to the power supply via the starter, and the starter is connected to the controller by a signal connection. The execution system includes a horizontal pipe, a vertical pipe, and a valve. The horizontal pipe is horizontally positioned, with one end covering and communicating with the wave-damping holes, and the other end connected to the vertical pipe. A valve is installed at the other end of the horizontal pipe, allowing selective communication between the horizontal pipe and the vertical pipe. The vertical pipe is vertically positioned, with the motor assembly installed at its top. The motor assembly opens when the pressure sensor detects that the real-time pressure on the moon pool enclosure wall reaches a first preset pressure value, thereby drawing gas from the vertical pipe. When the gas in the riser is drawn in and seawater flows into the horizontal pipe through the wave-damping hole, the valve opens when the pressure at the valve reaches the second preset pressure value under the combined action of seawater pressure and atmospheric pressure, so that the horizontal pipe and the riser are connected. Then the seawater flowing into the horizontal pipe will enter the riser through the valve, and the bottom end of the riser extends to the designated compartment, where the seawater can be collected.

[0023] During operation, this moon pool wave-damping device allows seawater to enter designated compartments through wave-damping holes when waves impact the moon pool's walls, thus achieving wave damping. The device covers the wave-damping holes, ensuring the watertightness and integrity of the moon pool's walls. This prevents hull components from being directly exposed to air and subjected to sea wind and seawater erosion, which could cause the anti-corrosion coating to peel off. This prevents surface corrosion and severe weakening of the structure's local strength, ensuring the operational safety of marine equipment. Furthermore, the moon pool wave-damping device is equipped with a detection system, providing emergency response capabilities for random wave impacts within the moon pool area. The detection system, through preset pressure thresholds and the power system's control of the motor components via starters, ensures that only the motor components in the impact area are operational, resulting in more efficient power distribution. The execution system, through preset valve pressure thresholds and control of motor components, enables a more rational distribution of mechanical energy. When encountering severe sea conditions, the system can efficiently absorb the wave energy generated by slamming, thereby preventing surges and ensuring the safety of equipment operating in the moon pool area.

The embodiments described below by reference to the drawings are exemplary and are only used to explain the present application, and cannot be understood as a limitation on the present application.

[0039] The technical solutions of the present application are further illustrated below in conjunction with the drawings and through specific embodiments.

[0040] As Figures 1 to 4As shown, the embodiment provides a moon pool wave absorbing device arranged in the upper wave area of the moon pool wall 100, the moon pool wall 100 is provided with a wave absorbing hole 1001, when the sea wave impacts the moon pool wall 100, the seawater can enter the designated cabin through the moon pool wave absorbing device from the wave absorbing hole 1001, thereby playing a wave absorbing effect. In addition, the moon pool wave absorbing device provided by the embodiment covers the wave absorbing hole 1001, ensuring the water tightness and integrity of the moon pool wall 100, so as to avoid the situation that the ship body member is directly exposed to the air due to the opening of the wave absorbing hole 1001, and the anticorrosive coating is peeled off and the surface of the member is corroded due to the erosion of the sea wind and seawater, ensuring that the local strength of the ship body is not affected, and ensuring the operation safety.

[0041] The moon pool wave absorbing device comprises a plurality of execution systems 1, a plurality of detection systems 2 and a plurality of power systems 3. Each detection system 2 comprises a signal-connected pressure sensor 21 and a controller 22, the pressure sensor 21 is arranged on the moon pool wall 100, and the pressure sensor 21 is used for detecting the real-time pressure on the moon pool wall 100. Each power system 3 comprises a starter 31, a power supply 32 and a motor assembly 33, the motor assembly 33 is electrically connected with the power supply 32 through the starter 31, and the starter 31 is signal-connected with the controller 22. The execution system 1 comprises a horizontal pipe 11, a vertical pipe 12 and a valve 13, the horizontal pipe 11 is horizontally arranged, one end of the horizontal pipe 11 covers and communicates with the wave absorbing hole 1001, the other end of the horizontal pipe 11 is connected with the vertical pipe 12, and the other end of the horizontal pipe 11 is provided with the valve 13, that is, the connection part of the horizontal pipe 11 and the vertical pipe 12 realizes selective communication through the valve 13. The vertical pipe 12 is vertically arranged, the motor assembly 33 is arranged at the top end of the vertical pipe 12, the motor assembly 33 can suck the gas in the vertical pipe 12 when the motor assembly 33 is started, and when the gas in the vertical pipe 12 is sucked and the seawater flows into the horizontal pipe 11 through the wave absorbing hole 1001, under the combined action of the seawater pressure and the atmospheric pressure, the valve 13 can be opened only when the pressure value at the valve 13 reaches the second preset pressure value, the seawater flowing into the horizontal pipe 11 enters the vertical pipe 12 through the valve 13, and since the bottom end of the vertical pipe 12 extends to the designated cabin, the seawater is immediately collected into the designated cabin.

[0042] To ensure that the execution system 1 only works when the sea water hits the moon pool wall 100, one execution system 1 is connected with one detection system 2, and each detection system 2 is set in the area where the execution system 1 is located and is signal connected with the execution system 1. When the sea wave hits the moon pool wall 100, the pressure sensor 21 detects that the real-time pressure on the moon pool wall 100 reaches the first preset pressure value, and the pressure sensor 21 converts the pressure signal into an electric signal and sends it to the controller 22, and the controller 22 gives an action signal to the starter 31, and the starter 31 is opened, so that a path is formed between the motor assembly 33 and the power supply 32, and the motor assembly 33 starts to work. When no sea water flows into the horizontal pipe 11, although the valve 13 will generate pressure under the suction of the motor assembly 33, the pressure value at the valve 13 does not reach the second preset pressure value, so the valve 13 will not be opened. The pressure value at the valve 13 will not reach the second preset pressure value under the suction of the motor assembly 33, and only when the horizontal pipe 11 is filled with sea water, the pressure value at the valve 13 will reach the second preset pressure value under the joint action of the sea water pressure and the atmospheric pressure, and the valve 13 will be opened, which can obviously improve the working efficiency and suction effect of the motor assembly 33. The specific structure of the motor assembly 33 can adopt the existing technology that can be controlled by the motor and can perform air suction, for example, the motor assembly 33 can adopt the combination of a motor and an air suction pump, the motor drives the air suction pump to start and stop, and the air suction pump is used to suck the gas in the vertical pipe 12. By using the motor assembly 33 to suck the air in the vertical pipe 12, the sea water flowing into the horizontal pipe 11 can be quickly sucked to the designated cabin after the valve 13 is opened.

[0043] During the operation of the moon pool wave suppression device, the water tightness and integrity of the moon pool wall 100 are ensured, and the corrosion problem of the ship body material is solved. The detection system 2 is set to respond to the random wave slamming in the moon pool area. The detection system 2 sets the pressure threshold, and the power system 3 controls the motor assembly 33 through the starter 31, so that only the motor assembly 33 in the slamming area is in working state, so that the distribution of electric energy of the system is more reasonable. The execution system 1 sets the pressure threshold at the valve 13 and controls the motor assembly 33, so that the distribution of mechanical energy of the system is more reasonable, and when encountering severe sea weather, the system can efficiently absorb the wave energy generated by the slamming, thereby avoiding the occurrence of the surge, and ensuring the safety of the moon pool area operation equipment.

[0044] As Figure 1As shown, in the embodiment, the execution system 1, the detection system 2 and the power system 3 are all provided in plurality, for the convenience of monitoring, the moon pool wave absorbing device provided in the embodiment further comprises a centralized control monitoring system 4, and the plurality of execution systems 1, the plurality of detection systems 2 and the plurality of power systems 3 are all controlled by the centralized control monitoring system 4. The controller 22 can feed back the running state of the motor assembly 33, the power supply 32 and the controller 22 itself to the centralized control monitoring system 4, so as to be able to monitor the running state of the moon pool wave absorbing device in real time. The centralized control monitoring system 4 in the embodiment of the application is a centralized control monitoring system 4 on a ship, which belongs to the prior art and will not be described here.

[0045] In the embodiment, the valve 13 can adopt a ball valve, the valve 13 is connected with an external control system and is controlled to open and close by the external control system, the external control system can be part of the above-mentioned centralized control monitoring system 4, and the valve 13 is controlled to open when the real-time pressure at the valve 13 reaches the second preset pressure value, and the real-time pressure at the valve 13 can be obtained by a pressure detection mechanism arranged at the valve 13.

[0046] The detection system 2 provided in the embodiment also considers a time delay protection measure in the program, that is, when the pressure sensor 21 detects that the real-time pressure on the moon pool surrounding wall 100 reaches the first preset pressure value, the starting time is prolonged to prevent the motor assembly 33 from being frequently started and stopped to affect the service life thereof. Alternatively, the motor assembly 33 is opened for a preset time t each time, and 15s≤t≤25s. For example, the motor assembly 33 is opened for 20s each time, and then the starting and stopping of the motor assembly 33 is re-judged according to the signal given by the pressure sensor 21.

[0047] Alternatively, as shown in FIG. 1, Figure 3 As shown, the other end of the horizontal pipe 11 is provided with a horn mouth 111, and the end with a larger flow area of the horn mouth 111 is connected with the wave absorbing hole 1001. When a large amount of seawater flows into the horizontal pipe 11 through the horn mouth 111, different flow rates are generated due to the cross-section change, so that a large internal and external pressure difference is formed, which can obviously improve the effect of the execution system 1 on seawater suction. In addition, when the seawater enters the horizontal pipe 11 through the wave absorbing hole 1001 on the moon pool surrounding wall 100, the water flow forms complex turbulence, which can offset a part of the wave energy generated by the slamming of the sea wave. With the opening of the valve 13, the wave energy generated by the slamming can also be largely absorbed by rapidly sucking the seawater of the sea wave into the vertical pipe 12.

[0048] Alternatively, as shown in FIG. 1, Figure 2As shown, each execution system 1 has a plurality of horizontal pipes 11, which are arranged at intervals along the extension direction of the vertical pipe 12, and the other end of one horizontal pipe 11 is communicated with one wave hole 1001. In specific implementation, a plurality of wave holes 1001 can be opened on the moon pool wall 100 according to requirements, and then a plurality of horizontal pipes 11 can be arranged, that is, one wave hole 1001 corresponds to one horizontal pipe 11. The plurality of wave holes 1001 can be divided into multiple rows and multiple columns in order, and then the extension direction of each column of wave holes 1001 can be arranged to be parallel to the extension direction of the vertical pipe 12, and the plurality of horizontal pipes 11 communicated with one column of wave holes 1001 can be communicated with one vertical pipe 12.

[0049] Alternatively, as shown in FIG. 2, each execution system 1 has two groups of horizontal pipes 11, which are arranged opposite to each other in the extension direction of the vertical pipe 12, and each group of horizontal pipes 11 includes a plurality of horizontal pipes 11 arranged at intervals along the extension direction of the vertical pipe 12, and the other end of one horizontal pipe 11 is communicated with one wave hole 1001. In specific implementation, on the basis of the plurality of wave holes 1001 being divided into multiple rows and multiple columns in order, the extension direction of each column of wave holes 1001 can be arranged to be parallel to the extension direction of the vertical pipe 12, and one group of horizontal pipes 11 can be arranged on each side of the extension direction of the vertical pipe 12, that is, the two groups of horizontal pipes 11 communicated with two columns of wave holes 1001 can be communicated with one vertical pipe 12, so as to reduce the number of execution systems 1. Figure 2 Further, each detection system 2 includes a plurality of pressure sensors 21, which are uniformly arranged at intervals, and when the real-time pressure detected by any one pressure sensor 21 reaches the first preset pressure value, the motor assembly 33 signal-connected with the pressure sensor 21 is started. If each execution system 1 includes a plurality of horizontal pipes 11, and the plurality of horizontal pipes 11 can be divided into two groups and arranged on both sides of the vertical pipe 12, that is, each execution system 1 can cover a plurality of wave holes 1001, and the plurality of wave holes 1001 are arranged on the moon pool wall 100 to enclose a certain area, then each detection system 2 can include a plurality of pressure sensors 21, and the plurality of pressure sensors 21 can be uniformly arranged at intervals in the area covered by one execution system 1, which can effectively improve the detection efficiency of the detection system 2. When the real-time pressure detected by any one pressure sensor 21 reaches the first preset pressure value, the motor assembly 33 signal-connected with the pressure sensor 21 is started, and when the real-time pressure reaches the second preset pressure value, the valve 13 is opened, so as to timely absorb the wave energy generated by the slamming.

[0050] Alternatively, as shown in FIG. 2, each execution system 1 has two groups of horizontal pipes 11, which are arranged opposite to each other in the extension direction of the vertical pipe 12, and each group of horizontal pipes 11 includes a plurality of horizontal pipes 11 arranged at intervals along the extension direction of the vertical pipe 12, and the other end of one horizontal pipe 11 is communicated with one wave hole 1001. In specific implementation, on the basis of the plurality of wave holes 1001 being divided into multiple rows and multiple columns in order, the extension direction of each column of wave holes 1001 can be arranged to be parallel to the extension direction of the vertical pipe 12, and one group of horizontal pipes 11 can be arranged on each side of the extension direction of the vertical pipe 12, that is, the two groups of horizontal pipes 11 communicated with two columns of wave holes 1001 can be communicated with one vertical pipe 12, so as to reduce the number of execution systems 1.

[0051] Figure 4 ​As shown, the distance between the other ends of two adjacent horizontal pipes 11 is equal along the extension direction of the vertical pipe 12. The distance between the other ends of two adjacent horizontal pipes 11 is equal along the extension direction of the vertical pipe 12. The wave absorbing holes 1001 are adapted to the structure of the execution system 1 to uniformly arrange the plurality of wave absorbing holes 1001, that is, the distance between the plurality of wave absorbing holes 1001 in each row of wave absorbing holes 1001 is consistent with the distance between the plurality of wave absorbing holes 1001 in each column of wave absorbing holes 1001, so as to uniformly absorb the wave energy everywhere and achieve the ideal wave absorbing effect. In the embodiment, the center distance between two adjacent wave absorbing holes 1001 in the horizontal direction is L, the center distance between two adjacent wave absorbing holes 1001 in the vertical direction is H, and L=H. In addition, the distance between the center of the vertical pipe 12 and the center of the wave absorbing hole 1001 in the horizontal direction is L1, and 2L1=L.

[0052] Alternatively, the cross-sectional area of the horizontal pipe 11 along the extension direction of the horizontal pipe 11 is a1, and the cross-sectional area of the vertical pipe 12 along the extension direction of the vertical pipe 12 is a2, and a2>a1. In specific implementation, the other end of each horizontal pipe 11 in the execution system 1 is connected with the same vertical pipe 12, so that the seawater flows through the horizontal pipe 11 and finally converges to the vertical pipe 12. In order to ensure the flow of seawater is not blocked, the cross-sectional area of the vertical pipe 12 needs to be larger than the cross-sectional area of the horizontal pipe 11, and the ratio of the cross-sectional area of the vertical pipe 12 to the cross-sectional area of the horizontal pipe 11 can be adjusted according to the number of horizontal pipes 11 connected with the same vertical pipe 12.

[0053] In the embodiment, the wave absorbing hole 1001 is a circular hole, so the horizontal pipe 11 and the vertical pipe 12 are both cylindrical pipes, and the two ends of the horn mouth 111 are also circular, and the large-diameter end of the horn mouth 111 covers the wave absorbing hole 1001.
