Description

Technical Field

[0001] This invention relates to the field of offshore photovoltaic piling vessel technology, specifically to an offshore photovoltaic piling vessel equipped with a skid-steer piling machine and a ship-moving trolley, and its method of use. Background Technology

[0002] Existing floating photovoltaic piling vessels consist of a floating body, a piling machine, and a positioning winch. For example, the Chinese publication CN114960740A, "Pile Foundation Fixed Support Structure, Floating Photovoltaic Power Station and Method," utilizes foundation piles to install a floating photovoltaic power station. However, the following problems still exist: (1) Poor environmental adaptability in shallow waters: The existing pile driving vessels are used for large-scale pile foundation construction in wind power, bridge and wharf projects. The vessels are large in size and have a deep draft, making them unsuitable for operation in shallow waters; (2) Low efficiency of positioning methods: The current positioning method for water pile driving vessels is anchoring, which cannot effectively constrain the movement of the vessel. Moreover, anchoring requires the coordination of anchoring boats, resulting in low operational efficiency; (3) High cost of moving within the construction site: The current method for moving water pile driving vessels is to pull the vessel by winding in the anchor cable after anchoring; (4) Poor accuracy of pile driving: The current water pile driving vessels generally cannot flexibly adjust the position of the pile driving machine, making it difficult to control the accuracy of pile alignment; (5) Adjustment of floating state: The adjustment of the floating state after the vessel tilts during the operation of the current water pile driving vessels is generally controlled by ballast water, which places high demands on the ballast system and results in slow adjustment of the floating state. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a marine photovoltaic piling vessel with a sliding pile driver and a ship-moving trolley and a method of using it, so as to achieve a ship technical solution with stable displacement and stable piling functions by combining the sliding pile driver and the ship-moving trolley.

[0004] The technical solution of this invention is as follows:

[0005] A marine photovoltaic piling vessel equipped with a skid-steer piling machine and a ship-moving trolley includes a piling vessel float and bow and stern positioning piles respectively installed at the front and rear of the float. The piling vessel float is fixed to the photovoltaic field in shallow waters where the foundation piles are to be driven by the bow and stern positioning piles. A skid-steer piling machine is installed on the bow deck of the piling vessel float. After the skid-steer piling machine hammers the foundation piles to be driven, a completed foundation pile is formed. The piling vessel float is also equipped with a ship-moving trolley, a longitudinal sliding rail assembly, a movable ballast, and a movable sliding rail assembly, wherein:

[0006] The ship-moving trolley is located on both sides of the stern of the piling vessel's floating body. It is used to move the sliding pile driver to the next work position of the foundation pile to be driven, and to control the lateral sliding adjustment of the sliding pile driver.

[0007] The longitudinal slide rail assembly, located below the ship-moving trolley, is used to control the longitudinal sliding adjustment of the sliding pile driver;

[0008] The mobile ballast is located between the ship-moving trolleys on both sides of the stern. It is used to move relative to the floating body of the piling vessel and to counteract the tilting and offset caused by different loads when the floating body of the piling vessel is lifting and sinking piles, thereby ensuring that the floating body of the piling vessel always remains in a balanced state.

[0009] The movable slide rail assembly, located below the movable ballast, is used to control the lateral sliding adjustment of the movable ballast.

[0010] Preferably, the offshore photovoltaic piling vessel includes the following multiple states:

[0011] The ship's positioning status, the bow positioning piles and stern positioning piles are driven into the seabed during the pile driving process to maintain the stability of the piling vessel's buoyancy;

[0012] In the overall moving state, after the foundation piles are completed and formed, the bow positioning pile is raised above the mud surface. The ship moving trolley uses hydraulic cylinders to push the piling vessel's floating body to the next work position with the stern positioning pile as the fulcrum. After it is in place, the bow positioning pile is sunk into the seabed to maintain the vessel's position. The stern positioning pile is raised above the mud surface, and the ship moving trolley uses hydraulic cylinders to push the stern positioning pile to the outside. After it is in place, the stern positioning pile is sunk into the seabed. After the bow and stern positioning piles stabilize the piling vessel's floating body, the construction of the foundation piles to be driven at the next work position begins, and the piles are driven and driven in succession.

[0013] To adjust the position, the sliding pile driver uses the longitudinal slide rail assembly below to fine-tune the longitudinal coordinates; and moves the vessel position laterally using the vessel trolley to fine-tune the lateral coordinates.

[0014] In a dynamic equilibrium state, the moving ballast slides laterally and longitudinally through the moving slide rail assembly, moving rapidly according to different piling operation conditions of the sliding piling machine to balance the floating state of the piling vessel.

[0015] Preferably, the maximum working flow velocity of the piling vessel float is 1 m / s, the maximum working wind speed is 10 m / s, and the significant wave height is 1.5 m / s; and the piling vessel float has a depth of 2.5 meters and a maximum draft of 0.9 meters, which meets the requirements for pile foundation construction in shallow water areas.

[0016] Preferably, in the shallow water photovoltaic field, there are several piles to be driven arranged in a matrix. The offshore photovoltaic piling vessel moves to the piles to be driven and hammers them one by one until all the piles to be driven in the shallow water photovoltaic field become completed piles.

[0017] Preferably, the longitudinal slide rail assembly includes a longitudinal slide rail, a longitudinal gear and rack mechanism, and a longitudinal drive motor, wherein:

[0018] The longitudinal slide rail is mounted on the deck of the piling vessel's floating hull and is a rack and pinion mechanism.

[0019] The longitudinal gear and rack mechanism meshes with the racks of the sliding pile driver and the deck rail respectively, and is used to drive the relative movement of the sliding pile driver;

[0020] The longitudinal drive motor, fixed on the sliding pile driver, is used to drive the longitudinal gear and rack mechanism to realize the relative movement between the longitudinal slide rail assembly, the piling vessel float and the sliding pile driver.

[0021] Preferably, the movable slide rail assembly includes a ballast tray structure, a two-way gear rack mechanism, and a two-way drive motor, wherein:

[0022] Ballast pallet structure, erected on the deck of the piling vessel's floating hull, with a two-way gear and rack mechanism on top;

[0023] A two-way gear rack mechanism meshes with the rack of the sliding rail of the floating deck of the moving ballast and piling vessel, and is used to drive the lateral and longitudinal movement of the moving ballast.

[0024] A bidirectional drive motor, fixed to the ballast pallet structure, is used to drive a bidirectional gear and rack mechanism to achieve relative movement between the longitudinal slide rail assembly and the moving ballast.

[0025] Preferably, the stern of the piling vessel float has grooves on both sides, guide rails on the edges of the grooves, and sliders mounted on the guide rails; a stern positioning pile and a ship-moving trolley are arranged along the guide rails, wherein the stern positioning pile is mounted on the slider, the hydraulic cylinder of the ship-moving trolley is mounted on the piling vessel float, and the hydraulic rod of the ship-moving trolley is connected to the stern positioning pile through the slider; the position of the stern positioning pile remains unchanged, and the piling vessel float moves relative to the stern positioning pile under the action of the retracting ship-moving trolley.

[0026] Preferably, the piling vessel buoy is also equipped with a compensation control system, which is connected to the longitudinal drive motor and the bidirectional drive motor respectively through a frequency converter rectifier module. The longitudinal drive motor and the bidirectional drive motor are controlled by an electronic control system.

[0027] Preferably, the compensation control system has the following five compensation modes: manual compensation mode, active pressure compensation mode, active position compensation mode, passive pressure compensation mode, and passive position compensation mode.

[0028] The technical solution of this invention is as follows:

[0029] A method for using an offshore photovoltaic piling vessel equipped with a skid-steer piling machine and a vessel-moving trolley includes the following steps:

[0030] S1. First, move the floating body of the piling vessel to the shallow water photovoltaic field where the foundation piles are to be driven. There are several foundation piles to be driven in the shallow water photovoltaic field arranged in a matrix.

[0031] S2. Before driving the pile, the distance between the sliding pile driver and the pile to be driven is adjusted by the ship-moving trolley. After the pile is aligned, the bow positioning pile and stern positioning pile are driven into the seabed to maintain the stability of the piling vessel. The longitudinal position of the sliding pile driver is adjusted again by the longitudinal rail assembly, and the lateral position of the sliding pile driver is adjusted by the ship-moving trolley.

[0032] S3. During pile driving, the sliding pile driver uses a moving ballast through the moving slide rail assembly to offset the tilting and offset caused by different loads when the pile driving vessel floats up and down, thereby ensuring that the pile driving vessel floats always maintain a balanced state.

[0033] S4. Repeat step S3 until the pile to be driven at the current position is completed, then proceed to the next step.

[0034] S5. When the trolley returns to its position, the entire vessel is in a moving state. After the foundation piles are driven and the completed foundation piles are formed, the bow positioning pile is raised above the mud surface. The trolley moves the floating body of the piling vessel to the next work position by using the hydraulic cylinder with the stern positioning pile as the fulcrum. After it is in place, the bow positioning pile sinks into the seabed to maintain the position of the vessel.

[0035] S6. When moving the vessel, the stern positioning pile is raised above the mud surface. The vessel moving trolley pushes the stern positioning pile to the outside using hydraulic cylinders. After it is in place, the stern positioning pile sinks into the seabed. After the bow and stern positioning piles keep the piling vessel stable, the construction of the next pile to be driven begins, and the piles are driven one by one.

[0036] Compared with the prior art, the present invention has the following advantages:

[0037] (1) High construction safety: Due to its high adaptability to environmental conditions, it can resist a certain degree of environmental loads such as wind, waves and currents. Its small draft can avoid shallow water operations from touching the bottom due to the influence of tides, and the safety during the operation process is greatly improved.

[0038] (2) Improve piling efficiency: The piling vessel is moved on-site by using a ship-moving trolley to push it, avoiding the inefficient and costly operation methods of anchoring the piling vessel with anchor boats and using anchor cable tensioning for relocation in the traditional construction process; the use of mobile ballast blocks to adjust the buoyancy of the vessel is highly efficient and saves operation time compared to ballast water ballasting and unloading.

[0039] (3) Reduce construction costs: Avoid the anchor boat to keep anchoring with the pile driving vessel, and do not use the anchor boat for positioning and on-site relocation, thus reducing the cost of using auxiliary vessels and equipment;

[0040] (4) High operational flexibility and high precision: The small size of the hull allows for flexible operation in shallow waters and areas with dense pile foundations; the sliding pile driver can slide laterally, effectively controlling the accuracy of the pile foundation construction position; the use of positioning piles driven into the seabed effectively stabilizes the hull and prevents the ship from floating freely, thus ensuring the accuracy of pile driving.

[0055] The movable slide rail assembly 8 is located below the movable ballast 7 and is used to control the lateral sliding adjustment of the movable ballast 7.

[0056] Preferably, the offshore photovoltaic piling vessel includes the following multiple states:

[0057] During the ship's positioning, the bow positioning pile 2 and the stern positioning pile 3 are driven into the seabed during the driving of the foundation pile 10 to maintain the stability of the piling vessel's floating body 1.

[0058] In the overall moving state, after the foundation pile 10 is driven and the foundation pile 9 is completed, the bow positioning pile 2 and the stern positioning pile 3 are raised to be above the mud surface. The ship moving trolley 5 pushes the piling vessel floating body 1 to the next work position.

[0059] To adjust the state, the sliding pile driver 4 uses the longitudinal slide rail assembly 6 installed below to fine-tune the longitudinal coordinates; and moves the ship position laterally using the ship trolley 5 to fine-tune the lateral coordinates.

[0060] In a dynamic equilibrium state, the moving ballast 7 slides laterally and longitudinally through the moving slide rail assembly 8, and moves rapidly according to the different piling operation conditions of the sliding pile driver 4, thus balancing the floating state of the piling vessel float 1.

[0071] Preferably, such as Figure 3 and Figure 4 As shown, the stern of the piling vessel float 1 is provided with grooves 11 on both sides, and guide rails 12 are provided on the edges of the grooves 11. A slider 53 is installed on the guide rails 12. A stern positioning pile 3 and a ship-moving trolley 5 are provided along the direction of the guide rails 12. The stern positioning pile 3 is installed on the slider 53, and the hydraulic cylinder 51 of the ship-moving trolley 5 is installed on the piling vessel float 1. The hydraulic rod 52 of the ship-moving trolley 5 is connected to the stern positioning pile 3 through the slider 53. The position of the stern positioning pile 3 remains unchanged, and the piling vessel float 1 moves relative to the stern positioning pile 3 under the drive of the retracting ship-moving trolley 5.

[0072] Preferably, the piling vessel buoy 1 is also equipped with a compensation control system, which is connected to the longitudinal drive motor and the bidirectional drive motor respectively through a frequency converter rectifier module, and the longitudinal drive motor and the bidirectional drive motor are controlled by electronic control.

[0073] Preferably, the compensation control system has the following five compensation modes: manual compensation mode, active pressure compensation mode, active position compensation mode, passive pressure compensation mode, and passive position compensation mode.

[0074] In manual compensation mode, position and pressure sensors are used to collect relevant information from the compensation control system, and the handle is used to drive the longitudinal drive motor and the bidirectional drive motor for reverse compensation, thereby ensuring that the sliding pile driver 4 and the moving ballast 7 remain relatively constant.

[0075] The active pressure compensation mode includes the following steps: using historical data from the compensation control system, a prediction model is established; based on the real-time feedback of the pressure difference between the moving ballast 7 and the sliding pile driver 4 and the set target pressure, and the pressure change caused by the external excitation predicted by the prediction model at the next moment, the output of the longitudinal drive motor and the bidirectional drive motor is calculated, and active compensation is performed using the frequency converter rectifier module.

[0076] The active position compensation mode includes the following steps: using historical data from the compensation control system, a predictive model is established; based on the real-time feedback of the relative position of the gear and rack mechanism, the deviation between the actual position and the set position of the drive motor, and the predicted changes in the position of the gear and rack mechanism and the actual position of the drive motor at the next moment, the relative position of the gear and rack mechanism and the elongation of the drive motor are calculated and output to the gear and rack mechanism, thereby adjusting the position of the drive motor in the horizontal direction; and the drive motor is actively compensated by adjusting the drive motor using the inverter rectifier module.

[0077] The passive pressure compensation mode includes the following steps: Using historical data from the compensation control system, a predictive model is established. Based on the real-time feedback of the pressure difference between the moving ballast 7 and the sliding pile driver 4 and the set target pressure, the torque and thrust of the longitudinal drive motor and the bidirectional drive motor are calculated and output. This allows the inverter rectifier module to drive the motor for reverse pressure compensation, ensuring a relatively constant pressure between the sliding pile driver 4 and the moving ballast 7; or a gear and rack mechanism is used to compensate for the horizontal interaction force between the sliding pile driver 4 and the moving ballast 7.

[0078] The passive position compensation mode includes the following steps: using historical data from the compensation control system, a predictive model is established. Based on the deviation between the real-time feedback positions of the gear and rack mechanism, the moving ballast 7, and the sliding pile driver 4 and the set positions, the relative position of the output gear and rack mechanism and the extension of the drive motor are calculated. The motor is then driven by the frequency converter rectifier module to perform position compensation, thereby ensuring that the sliding pile driver 4 and the moving ballast 7 remain relatively constant; or the gear and rack mechanism is used simultaneously to compensate for the relative position changes in the horizontal plane between the sliding pile driver 4 and the moving ballast 7.

[0079] Example 2

[0080] Based on Example 1, such as Figure 1 As shown, the present invention provides a method for using an offshore photovoltaic piling vessel equipped with a skid-steer piling machine and a vessel-moving trolley, comprising the following steps:

[0081] S1. First, move the piling vessel buoy 1 to the shallow water photovoltaic field where the piles to be driven 10 are located. There are several piles to be driven 10 arranged in a matrix in the shallow water photovoltaic field.

[0082] S2. Before driving the pile, the distance between the sliding pile driver 4 and the pile to be driven 10 is adjusted by the ship-moving trolley 5. After the pile is aligned, the bow positioning pile 2 and the stern positioning pile 3 are driven into the seabed to maintain the stability of the piling vessel buoy 1. The longitudinal position of the sliding pile driver 4 is adjusted again by the longitudinal slide rail assembly 6, and the lateral position of the sliding pile driver 4 is adjusted by the ship-moving trolley 5.

[0083] S3. During pile driving, the sliding pile driver 4 moves the ballast 7 through the moving slide rail assembly 8 to offset the tilting and offset caused by different loads when the pile driving vessel float 1 is lifting and driving the pile, thereby ensuring that the pile driving vessel float 1 always maintains a balanced state.

[0084] S4. Repeat step S3 until the pile to be driven 10 at the current position is transformed into a completed pile 9, then proceed to the next step.

[0085] S5. When the trolley returns to its position, the entire vessel is in motion. After the foundation pile 10 is driven and the completed foundation pile 9 is formed, the bow positioning pile 2 is raised above the mud surface. The trolley 5 uses the hydraulic cylinder 51 to push the piling vessel float 1 to the next work position with the stern positioning pile 3 as the fulcrum. After it is in place, the bow positioning pile 2 sinks into the seabed to maintain the vessel's position.

[0086] S6. When moving the ship, the stern positioning pile 3 is raised above the mud surface. The ship moving trolley 5 pushes the stern positioning pile 3 to the outside through the hydraulic cylinder 51. After it is in place, the stern positioning pile 3 sinks into the seabed. After the bow positioning pile 2 and the stern positioning pile 3 keep the piling vessel floating body 1 stable, the construction of the foundation pile 10 to be driven at the next work position begins, and the piles are driven one by one by hammering.
