Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of intelligent ballast of a buoyant body on a barge, and particularly relates to an intelligent ballast method and system of a buoyant body on a barge. BACKGROUND

[0002] In the process of transferring a buoyant body such as a pipe section of a immersed tube to a barge on barge (such as a semi-submersible barge), a bottom-sitting on barge method is generally adopted, and during the on barge process, the ballast water of the barge on barge is manually calculated and manually adjusted. With the increase of the weight and volume of the existing buoyant body, the difficulty of manually calculating the on barge scheme of the buoyant body increases, and the calculation amount is large. Moreover, because the manual operation method is relatively cumbersome and the manual adjustment is delayed, the control of the ballast water of the semi-submersible barge during the on barge process is not intuitive enough, and the on barge period is affected. SUMMARY

[0003] The present application aims at the problem that the prior art needs to control the ballast water of the barge on barge by using an intelligent ballast method to reduce the calculation amount, make the process control more intuitive, and shorten the on barge period, and provides an intelligent ballast method and system of a buoyant body on a barge.

[0004] In order to achieve the above-mentioned purpose, the technical scheme adopted by the present application is as follows:

[0005] In a first aspect, the present application provides an intelligent ballast method of a buoyant body on a barge, comprising the following steps:

[0006] S1, a new operation process is created, and the calculation length, the calculation step d, the operation time, the operation time length and the buoyant body information are inputted;

[0007] S2, an on barge operation scheme of the buoyant body is automatically calculated according to the calculation length, the calculation step d, the operation time, the operation time length and the buoyant body information, and the on barge operation scheme comprises the 0th step to the Nth step, each step comprises the step operation time length and the ballast water distribution result of the barge on barge;

[0008] S3, the on barge operation scheme is automatically executed step by step from the 0th step to the Nth step, when the 0th step is executed: the ballast water of the barge on barge is adjusted according to the ballast water distribution result of the barge on barge so that the deck surface of the barge on barge is flush with the wharf surface; when the 1st step is executed: the buoyant body is on barge by using the buoyant body bottom lifting vehicle according to the operation time and the step operation time length of the 1st step, and the ballast water of the barge on barge is adjusted according to the step operation time length of the 1st step and the ballast water distribution result of the barge on barge; when the 2nd step to the Nth step are executed: the buoyant body is on barge by using the buoyant body bottom lifting vehicle according to the step operation time length of each step, and the ballast water of the barge on barge is adjusted according to the step operation time length of each step and the ballast water distribution result of the barge on barge;

[0009] S4, after the end of the Nth step, the intelligent ballast of the barge ship is completed.

[0010] The intelligent ballast method of the buoyant body barge of the application automatically calculates the barge operation scheme of the buoyant body according to the calculation length, the calculation step d, the operation time, the operation time length and the buoyant body information, then automatically executes the 0th step to the Nth step according to the barge operation scheme, and adjusts the ballast water of the barge ship according to each step of the barge operation scheme. After the automatic calculation of all steps of the barge operation scheme is completed, the barge operation scheme is continuously and automatically executed according to each step of the barge operation scheme. The calculation amount is small, the process is continuous, the ballast water of the barge ship is mainly controlled, the control is more intuitive, and the period of the barge is shortened.

[0011] As a preferred scheme of the application, the buoyant body information includes the weight of the front end of the buoyant body at different cross sections in the longitudinal direction of the buoyant body;

[0012] When the buoyant body bottom lifting vehicle and the buoyant body are separate structures, the calculation length is the horizontal distance from the first end of the buoyant body to the tail end of the barge ship deck; when the lifting vehicle and the buoyant body are integrated, the calculation length is the horizontal distance from the first wheel shaft point of the lifting vehicle to the tail end of the barge ship deck;

[0013] The calculation step d is the barge distance of the buoyant body in each step;

[0014] The operation time is the starting operation time of the buoyant body barge operation;

[0015] The operation time length is the total operation time length of the barge operation.

[0016] As a preferred scheme of the application, in step S2, the cabin ballast water of the barge ship is distributed according to the symmetry and moment balance principle to obtain the ballast water distribution result of the barge ship;

[0017] The symmetry and moment balance principle is that the moment of the bow part relative to the overall center of gravity is equal to the moment of the stern part relative to the overall center of gravity, and the overall center of gravity is the center of gravity of the overall barge ship, the buoyant body that has been barged, the lifting vehicle corresponding to the buoyant body that has been barged, and the ballast water.

[0018] The overall center of gravity determined in this way is more accurate, so that the obtained ballast water scheme is more accurate and precise.

[0019] As a preferred scheme of the application, the moment of the bow part relative to the overall center of gravity includes the moment of the bow part of the barge ship relative to the overall center of gravity, the moment of the bow part ballast water relative to the overall center of gravity, the moment of the bow part of the buoyant body that has been barged relative to the overall center of gravity, and the moment of the bow part of the lifting vehicle that has been barged relative to the overall center of gravity;

[0020] The moment of the stern part relative to the overall center of gravity comprises a moment of the stern part of the barge relative to the overall center of gravity, a moment of the stern part ballast water relative to the overall center of gravity, a moment of the stern part of the already barged buoyancy body relative to the overall center of gravity, and a moment of the stern part of the already barged lifting vehicle relative to the overall center of gravity.

[0021] As a preferred scheme of the present application, the overall center of gravity is replaced by the center of the barge;

[0022] The moment of the bow part relative to the center of the barge comprises only a moment of the bow part ballast water relative to the center of the barge, a moment of the bow part of the already barged buoyancy body relative to the center of the barge, and a moment of the bow part of the already barged lifting vehicle relative to the center of the barge.

[0023] The moment of the stern part relative to the center of the barge comprises only a moment of the stern part ballast water relative to the center of the barge, a moment of the stern part of the already barged buoyancy body relative to the center of the barge, and a moment of the stern part of the already barged lifting vehicle relative to the center of the barge.

[0024] The stern part is the end of the barge close to the wharf, and the bow part is the end of the barge away from the wharf.

[0025] The overall center of gravity is replaced by the center of the barge, and under the premise that the load adjustment of the barging scheme can meet the demand, the calculation amount can be reduced.

[0026] As a preferred scheme of the present application, in step S2, the step of obtaining the ballast water distribution result of the barge at each step of the barging scheme is as follows:

[0027] The draft Ap of the barge at each step is calculated 吃水 ; the displacement weight w corresponding to the draft of the barge is calculated according to Ap 吃水 ; the total weight w of the buoyancy body and the lifting vehicle that have been barged is obtained 排总 ; the amount of ballast water W required for the barge at the current step corresponding to the draft is calculated according to w 货驳 , w 排总 , w 货驳 , and the weight b of the barge itself 压载水 ;

[0028] The moment of the bow part relative to the overall center of gravity is the sum of the moment of the bow part ballast water relative to the center of the barge and the moment of the bow part of the already barged buoyancy body and the bottom lifting vehicle relative to the center of the barge, and the moment of the stern part relative to the overall center of gravity is the sum of the moment of the stern part ballast water relative to the center of the barge and the moment of the stern part of the already barged buoyancy body and the bottom lifting vehicle relative to the center of the barge; the symmetry and moment balance principle formula is as follows:

[0029] F1*L1+F W1 *L3=F2*L2+F W2 *L4;

[0030] W 压载水 =F W1 +F W2 ;

[0031] W 货驳 =F1+F2;

[0032] Wherein, F1 is the weight of the floating body and the lifting vehicle on the barge at the bow of the ship, L1 is the distance from the center of the barge to the center of gravity of the floating body and the lifting vehicle on the barge at the bow of the ship, F W1 is the amount of ballast water in the cabin at the bow of the barge, and L3 is the distance from the center of the barge to the center of gravity of the ballast water at the bow of the barge; F2 is the weight of the floating body and the lifting vehicle on the barge at the stern of the ship, L2 is the distance from the center of the barge to the center of gravity of the floating body and the lifting vehicle on the barge at the stern of the ship, F W2 is the amount of ballast water in the cabin at the stern of the barge, and L4 is the distance from the center of the barge to the center of gravity of the ballast water at the stern of the barge.

[0033] As a preferred scheme of the present application, the draft Ap 型深 of the barge at the current step is calculated according to the depth D 码头 of the barge, the height H 潮位 of the wharf and the height H 吃水 of the tide at the current step, and the calculation formula of Ap 吃水 is: Ap 吃水 =D 型深 -(H 码头 -H 潮位 );

[0034] There is a slope a between Ap 吃水 and w 排总 , and the calculation formula of w 排总 is: w 排总 =Ap 吃水 / a;

[0035] The calculation formula of W 货驳 is w 货驳 =d*n*c, wherein d is the calculation step, n is the nth step of the barge loading scheme, n∈N, and c is the weight of the floating body and the lifting vehicle per meter in the longitudinal direction; or the floating body on the barge section is obtained through d*n, the weight of the floating body on the barge is obtained according to the floating body information read from the floating body on the barge section, and the weight of the lifting vehicle on the barge is obtained according to the floating body on the barge section; W 货驳 is the sum of the weight of the floating body on the barge and the weight of the lifting vehicle on the barge;

[0036] W 压载水W 压载水 = W 排总 -b-W 货驳 ;

[0037] According to the d*n, the length of the floating body that has been on the barge is obtained, and according to the length of the floating body that has been on the barge and the center of the on-barge barge, the length of the bow of the ship that has been on the floating body and the length of the stern of the ship that has been on the floating body are determined; according to the length of the bow of the ship that has been on the floating body, the center of gravity of the bow of the ship that has been on the floating body and the lifting force vehicle is determined, and according to the center of gravity of the bow of the ship that has been on the floating body and the lifting force vehicle and the center of the on-barge barge, L1 is determined; according to the length of the stern of the ship that has been on the floating body, the center of gravity of the stern of the ship that has been on the floating body and the lifting force vehicle is determined, and according to the center of gravity of the stern of the ship that has been on the floating body and the lifting force vehicle and the center of the on-barge barge, L2 is determined;

[0038] According to the formula of the symmetry and the moment balance principle, F W1 , F W2 , L3 and L4 are determined, and then the ballast water distribution result of the on-barge barge of the current step is obtained.

[0039] By using the above formula, the required distribution weight of the ballast water of the bow and the stern of the ship at each step can be quickly and accurately obtained.

[0040] As a preferred scheme of the present application, in step S2, after the on-barge operation scheme at each step is calculated, the stability of the on-barge barge of the on-barge operation scheme, the longitudinal and transverse inclination of the deck of the on-barge barge, the deflection of the on-barge barge, the bending moment and the shear force of the on-barge barge are calculated to realize the checking.

[0041] If the stability, the inclination angle, the deflection, the bending moment and the shear force of the on-barge operation scheme at the current step all meet the requirements, the on-barge operation scheme at the next step is calculated.

[0042] If the stability, the inclination angle, the deflection, the bending moment or the shear force of the on-barge operation scheme at the current step does not meet the requirements, the on-barge operation scheme at the current step is recalculated, and then the stability of the on-barge barge of the on-barge operation scheme, the longitudinal and transverse inclination of the deck of the on-barge barge, the deflection of the on-barge barge, the bending moment and the shear force of the on-barge barge are calculated to realize the checking again until the requirements are met, and then the on-barge operation scheme at the next step is calculated.

[0043] The on-barge operation scheme at each step is calculated in sequence until the on-barge operation scheme at the Nth step realizes the checking to generate the on-barge operation scheme.

[0044] In step S3, after each step is executed, it is judged whether the stability of the on-barge barge, the longitudinal and transverse inclination of the deck of the on-barge barge, the deflection of the on-barge barge, the bending moment and the shear force of the on-barge barge meet the control requirements, and whether the ballast water distribution result of the on-barge barge meets the on-barge operation scheme, if yes, the next step is executed, and if not, the ballast water is adjusted according to the on-barge operation scheme at the current step.

[0045] The above-mentioned mode, after calculating each step of the unloading operation scheme, checks the stability of the unloading barge, the trim and heeling of the deck of the unloading barge, the deflection of the unloading barge, the bending moment and shear force of the unloading barge, and then calculates the next step of the unloading operation scheme, thereby reducing the superimposed error of the subsequent unloading operation scheme, ensuring that each step of the unloading operation scheme meets the requirements, and reducing the problems of construction safety and affecting the construction period in subsequent execution of the unloading operation scheme; after each step is executed, it is judged whether the stability of the unloading barge, the trim and heeling of the deck of the unloading barge, the deflection of the unloading barge, the bending moment and shear force of the unloading barge meet the control requirements, so as to determine whether the load adjustment is in place, thereby avoiding the danger of unloading construction.

[0046] As a preferred scheme of the present application, before step S1, it further includes creating a buoyant body: importing the name definition and buoyant body information of the buoyant body.

[0047] In a second aspect, the present application provides an intelligent load adjustment system for buoyant body unloading, which is used to execute the intelligent load adjustment method for buoyant body unloading, and includes a monitoring module, an unloading barge load adjustment module, a load distribution calculation module and a hydraulic valve control system.

[0048] The load distribution calculation module is used to generate an unloading operation scheme.

[0049] The monitoring module collects the bending moment, shear force and deflection data of the unloading barge and the amount of ballast water in each ballast tank of the unloading barge in real time during the unloading process of the buoyant body, and compares the bending moment, shear force and deflection data of the unloading barge with the safety set value respectively.

[0050] The unloading barge load adjustment module executes the unloading operation scheme calculated by the load distribution calculation module according to the real-time data collected by the monitoring module, and automatically controls the adjustment of the ballast water through the hydraulic valve control system.

[0051] If one of the bending moment, shear force and deflection of the unloading barge exceeds the safety set value, the unloading of the buoyant body is stopped, and then the automatic control of the ballast water adjustment of the unloading barge load adjustment module is switched to manual operation intervention, and after the intervention, the unloading operation scheme is regenerated by the load distribution calculation module, and then the manual operation is switched to the automatic control of the ballast water adjustment, and the buoyant body continues to unload.

[0052] The intelligent load adjustment system for buoyant body unloading can quickly and accurately calculate the unloading operation scheme of each step of the buoyant body, and safely and efficiently execute the unloading operation scheme of each step.

[0053] As described above, due to the adoption of the above technical scheme, the present application has the following beneficial effects:

The intelligent ballast method for the barge loading of the buoyant body, according to the calculated length, the calculated step d, the operation time, the operation time length and the buoyant body information, the barge loading operation scheme of the buoyant body is automatically calculated, then the 0th step to the Nth step are automatically executed step by step according to the barge loading operation scheme, and the ballast water of the barge is adjusted according to each step of the barge loading operation scheme, after the barge loading operation scheme of all steps is automatically calculated and completed, the barge loading operation scheme is continuously and automatically executed, the calculation amount is small, the process is continuous, the ballast water of the barge is mainly controlled, the control is more intuitive, and the period of the barge loading is shortened.

[0079] Embodiment 1

[0080] The present embodiment provides an intelligent ballast method for a buoyant body on a barge, as shown in Figure 1 , comprising the following steps:

[0081] S1, new operation process: input calculation length, calculation step d, operation time, operation time length and buoyant body information;

[0082] The buoyant body information includes the weight of the front end of the buoyant body at different cross sections in the longitudinal direction; the weight of the buoyant body entering the semi-submersible barge can be determined according to the cross section of the buoyant body currently entering the barge and the buoyant body information, as shown in Figure 5 , which is further used to calculate the distribution of ballast water; the buoyant body can be a pipe section of a immersed tube, a wind power platform, etc. as shown in Figure 5 ; the barge can be a semi-submersible barge, etc. as shown in Figure 7 ;

[0083] When the buoyant body bottom lifting vehicle and the buoyant body are separate structures, the calculation length is the horizontal distance from the front end of the buoyant body to the tail end of the deck of the barge; when the lifting vehicle and the buoyant body are integrated, the calculation length is the horizontal distance from the first wheel shaft point of the lifting vehicle to the tail end of the deck of the barge; the first wheel shaft point refers to the longitudinal point of the first wheel shaft closest to the front end of the buoyant body.

[0084] The calculation step d is the up-barge distance of the buoyant body at each step, which represents the relationship between the rolling distance and the scheme calculation frequency. The software generates an up-barge operation scheme (mainly the ballast scheme of this step) for each calculation step d.

[0085] The operation time is the start time of the operation on the buoyant body, and the definition of this moment is to determine the tidal information;

[0086] The operation duration is the total operation duration of the barge operation, while the specific operation duration of the roll-on / roll-off operation is defined in order to determine the impact of tidal changes on the draft of the semi-submersible barge within the operation duration.

[0087] Assuming the calculation length is 140m, the calculation step size is 40m, the operation time is 2 hours, and the operation time is 2024 / 3 / 28, 14:43, then there are four steps: step 0 (0m), step 1 (uploading to 40m), step 2 (uploading to 80m), step 3 (uploading to 120m), and step 4 (uploading to 140m). The execution time of step 4 is 2024 / 3 / 28, 16:43.

[0088] S2. Generate the barge loading operation plan, such as Figure 2 As shown: The loading operation plan for the buoyant body is automatically calculated based on the calculation length, calculation step d, operation time, operation duration and buoyant body information. The loading operation plan includes steps 0 to N, and each step includes the operation duration and the ballast water distribution results of the loading barge.

[0089] In step S2, the ballast water volume of the upper barge is allocated according to the principles of symmetry and moment balance to obtain the ballast water distribution result of the upper barge;

[0090] The principle of symmetry and moment balance states that the moment of the bow relative to the overall center of gravity is equal to the moment of the stern relative to the overall center of gravity. The overall center of gravity is the center of gravity of the barge, the buoyancy body of the barge, the lifting vehicle corresponding to the buoyancy body of the barge, and the ballast water.

[0091] Furthermore, the moment of the bow section relative to the overall center of gravity includes the moment of the bow section of the barge relative to the overall center of gravity, the moment of the ballast water in the bow section relative to the overall center of gravity, the moment of the buoyancy body in the bow section relative to the overall center of gravity, and the moment of the lifting vehicle in the bow section relative to the overall center of gravity.

[0092] The moment of the stern relative to the overall center of gravity includes the moment of the stern of the barge relative to the overall center of gravity, the moment of the ballast water at the stern relative to the overall center of gravity, the moment of the buoyancy body at the stern relative to the overall center of gravity, and the moment of the lifting vehicle at the stern relative to the overall center of gravity.

[0093] When the barge is level, its center of gravity coincides with the center of gravity. As an optional implementation, the overall center of gravity is replaced by the center of the barge; that is, the moment of the bow relative to the center of the barge only considers the moment of the ballast water at the bow relative to the center of the barge, the moment of the buoyancy body at the bow relative to the center of the barge, and the moment of the barge lifting vehicle at the bow relative to the center of the barge; the moment of the stern relative to the center of the barge only considers the moment of the ballast water at the stern relative to the center of the barge, the moment of the buoyancy body at the stern relative to the center of the barge, and the moment of the barge lifting vehicle at the stern relative to the center of the barge; wherein, the stern is the end of the barge's center closer to the dock, and the bow is the end of the barge's center farther from the dock.

[0094] Optionally, in step S2, the steps for obtaining the ballast water distribution results of the barge at each step of the barge loading operation plan are as follows:

[0095] like Figure 3 As shown, calculate the draft Ap of the barge at each step. 吃水 According to the depth D of the upper barge 型深 , Wharf elevation H 码头 And the current tidal level H 潮位 Calculate the draft Ap of the barge in the current step. 吃水 Ap 吃水 The calculation formula is: Ap 吃水 =D 型深 -(H 码头 -H 潮位 );

[0096] According to Ap 吃水 Calculate the displacement weight w corresponding to the draft of the barge. 排总 Ap 吃水 and w 排总 There exists a slope a, w 排总 The calculation formula is: w 排总 =Ap 吃水 / a;

[0097] Obtain the total weight w of the buoyant body and the lifting vehicle already loaded onto the barge. 货驳 W 货驳 The calculation formula is w 货驳 =d*n*c, where d is the calculation step size, n is the nth step of the barge loading operation plan, n∈N, and c is the weight of the buoyant body and lifting vehicle per meter longitudinally; or obtain the cross-section of the buoyant body already loaded onto the barge through d*n, obtain the weight of the buoyant body front end already loaded onto the barge based on the buoyant body information read from the cross-section of the buoyant body already loaded onto the barge, and obtain the weight of the lifting vehicle already loaded onto the barge based on the cross-section of the buoyant body already loaded onto the barge; W 货驳 It is the sum of the weight of the front end of the buoyant body that has been loaded onto the barge and the weight of the lifting vehicle that has been loaded onto the barge;

[0098] According to w 排总 , w 货驳 and the self weight b of the barge, the amount of ballast water W required for the current step of the barge is calculated 压载水 ; the calculation formula of W 压载水 is: W 压载水 = W 排总 -b-W 货驳 ;

[0099] The moment of the bow part of the whole with respect to the center of gravity of the whole is the sum of the moment of the bow ballast water with respect to the center of the barge and the moment of the bow barge-float and the bottom lifting vehicle with respect to the center of the barge; the moment of the stern part of the whole with respect to the center of gravity of the whole is the sum of the moment of the stern ballast water with respect to the center of the barge and the moment of the stern barge-float and the bottom lifting vehicle with respect to the center of the barge; the symmetry and the moment balance principle formula are as follows:

[0100] F1*L1+F W1 *L3=F2*L2+F W2 *L4;

[0101] W 压载水 =F W1 +F W2 ;

[0102] W 货驳 =F1+F2;

[0103] Wherein, F1 is the barge-float and the lifting vehicle barge weight, L1 is the distance from the center of the barge to the center of the barge, as shown in Figure 6 ; F W1 is the amount of ballast water in the bow cabin of the barge, L3 is the distance from the center of the barge to the center of the barge; F2 is the barge-float and the lifting vehicle barge weight, L2 is the distance from the center of the barge to the center of the barge, F W2 is the amount of ballast water in the stern cabin of the barge, L4 is the distance from the center of the barge to the center of the barge;

[0104] Wherein, the length of the buoyancy body having been on the barge is obtained according to d*n, the length of the bow part of the buoyancy body having been on the barge and the length of the stern part of the buoyancy body having been on the barge are determined according to the length of the buoyancy body having been on the barge and the center of the barge; the center of gravity of the buoyancy body and the lifting vehicle having been on the bow part of the barge is determined according to the length of the buoyancy body having been on the bow part of the barge, and L1 is determined according to the center of gravity of the buoyancy body and the lifting vehicle having been on the bow part of the barge and the center of the barge; the center of gravity of the buoyancy body and the lifting vehicle having been on the stern part of the barge is determined according to the length of the buoyancy body having been on the stern part of the barge, and L2 is determined according to the center of gravity of the buoyancy body and the lifting vehicle having been on the stern part of the barge and the center of the barge;

[0105] F is determined according to the symmetry and the moment balance principle formula W1 , F W2 , L3 and L4, and then the ballast water distribution result of the barge at the current step is obtained, i.e. the on-barge operation scheme at the current step is obtained.

[0106] In step S2, after the on-barge operation scheme at each step is calculated, the stability of the barge at the on-barge operation scheme, the inclination and the heeling of the deck of the barge, the deflection of the barge, the bending moment and the shear force of the barge are calculated to realize the checking.

[0107] If the stability, the inclination angle, the deflection, the bending moment and the shear force of the barge at the on-barge operation scheme at the current step all meet the requirements, the on-barge operation scheme at the next step is calculated.

[0108] If the stability, the inclination angle, the deflection, the bending moment or the shear force of the barge at the on-barge operation scheme at the current step does not meet the requirements, the on-barge operation scheme at the current step is recalculated, and then the stability of the barge at the on-barge operation scheme, the inclination and the heeling of the deck of the barge, the deflection of the barge, the bending moment and the shear force of the barge are calculated to realize the checking again until the requirements are met, and then the on-barge operation scheme at the next step is calculated. In the above embodiment, there are n choices of the on-barge operation scheme calculated by the symmetry and the moment balance principle formula, the checking is realized by the traversal, the calculation is performed again to obtain the on-barge operation scheme at the current step which meets the symmetry and the moment balance principle, the stability, the inclination angle, the deflection, the bending moment and the shear force, and the operation safety is ensured, as shown in Figure 4 .

[0109] The on-barge operation scheme at each step is calculated in sequence until the on-barge operation scheme at the Nth step realizes the checking to generate the on-barge operation scheme.

[0110] Taking a 20,000-ton buoyancy body as an example. The buoyancy body is 130 m long, 50 m wide, 10 m high, and weighs 19424 tons, and the roll-on roll-off weight is about 22000 tons. The on-barge operation time is about 2 hours, the step length is 10 steps, and each step is 12 minutes. The 0th step is the initial state, and the buoyancy body has not been on the barge.

[0111] When the wharf and the deck are always flush, the draft formula of the barge is:

[0112] Ap 吃水 (Actual) = the data collected by the monitoring module 型深 -(H 码头 -H 潮位 );

[0113] Ap 吃水 (Actual) = the data collected by the monitoring module

[0114] Ap and the inclination angle (calculated) = (the weight of the barge itself b + the weight distribution of the floating body on the barge + the weight distribution of the cabin ballast on the barge); wherein the weight distribution of the floating body on the barge refers to the weight of the floating body that has been on the barge, and the weight of the lifting vehicle on the barge is removed in this formula, mainly because the weight of the lifting vehicle is much smaller than the weight of the floating body, and can be omitted for calculation, which is smaller in calculation amount; the weight distribution of the cabin ballast on the barge is the amount of ballast water W 压载水 required for the corresponding draft of the barge on the barge.

[0115] To meet the requirements of the roll-on barge, i.e.

[0116] The weight distribution of the cabin ballast on the barge is shown in the following table:

[0117]

[0118] The ballast tank is divided into four groups of ballast tanks, and according to the symmetrical ballast principle, the cabin of the floating body on the barge is drained, and the tail is pressurized to maintain the moment balance.

[0119] Regarding the change of tidal level at each step, the tidal level benchmark of the maritime bureau is taken as the benchmark, and the tidal level change table in the following operation time is obtained by querying the national marine information official website.

[0120]

[0121] Regarding the calculation step d, if 10 steps are used to complete the on-boarding, the distance of the floating body on the barge is divided by 10 steps to obtain the calculation step d.

[0122] Regarding the floating body information, the floating body walks on the pile cap 110m, and is walked into position in 10 steps, from right to left, the first cross section corresponds to the floating body on the barge weight of 0t (indicating that it has not been on the barge), the second cross section corresponds to the floating body on the barge weight of 2200t (indicating the floating body on the barge weight after the first step on the barge), the third cross section corresponds to the floating body on the barge weight of 2200t+2200=4400t (indicating the floating body on the barge weight after the second step on the barge), and so on.

[0123] The main principle of moment balance is to divide the ballast tank into three parts, front, middle and rear, through moment calculation, combined with the barge floating state, the main loading of the three parts is obtained, and then combined with the pipeline loading characteristics of the barge, the specific loading sequence is planned. Combined with the design data of the barge, the stability data of the typical working condition, the calculation results are generated.

[0124] Wherein, the barge weight b = 25000, the barge weight b includes the barge weight itself plus the initial oil storage inside;

[0125] Step 0 calculation, as shown in Figure 8 :

[0126] Control conditions: 1. The wharf is flush with the stern of the lifting deck, and the height difference between the wharf and the deck is controlled within -10cm-0; 2. The barge floating state is as level as possible, and the roll is controlled within ±20cm; 3. The barge keeps a certain amount of stern, and the pitch is controlled within -30cm-0; 4. The barge longitudinal centerline is aligned with the buoyancy body centerline; 5. The total amount of barge ballast water should be able to replace the weight of the barge platform.

[0127] Prepare to barge, Ap 吃水 = D 型深 -(H 码头 -H 潮位 ) = 10.2-(8.15-2.05) = 4.1m, 12:07 maritime bureau tide 205cm.

[0128] Corresponding displacement slope a = 2.299 / 24029.3; the corresponding displacement slope a represents the relationship between the barge draft and the displacement weight w 排总 and Ap 吃水 , both of which form a sink-float curve, after obtaining Ap 吃水 , w 排总 can be obtained according to the sink-float curve;

[0129] The barge draft corresponding to the displacement weight w 排总 = Ap 吃水 / a = 4.1 / (2.299 / 24029.3) = 42853.5;

[0130] The barge corresponding to the draft required ballast water volume W 压载水 = W 排总 -b-W 货驳 = 42853.5-25000-0 = 17853.5;

[0131] Determine F W1 , F W2 , L3 and L4 according to the symmetry and moment balance principle formula, and then obtain the ballast water distribution result of the barge at the current step;

[0132] F1*L1+F W1 *L3=F2*L2+F W2 *L4; i.e., 0+F W1 *L3=0+F W2 *L4;

[0133] W 压载水 =F W1 +F W2 That is, 17853.5 = F W1 +F W2 ;

[0134] W 货驳 =F1+F2; that is, 0=0+0;

[0135] Step 1 calculation, such as Figure 9 As shown:

[0136] Control conditions: 1. The stern of the dock and the lifting deck should be flush, and the height difference between the dock and the deck surface should be controlled within -10cm to 0; 2. The lateral heel of the upper barge should be as close to 0 as possible, and the lateral heel should be controlled within ±20cm; 3. The upper barge should maintain a certain stern heel, and the longitudinal heel should be controlled within -30cm to 0; 4. The longitudinal centerline of the upper barge should be aligned with the centerline of the buoyancy body; 5. The total adjustable ballast water volume of the upper barge should be able to replace the weight of the buoyancy body.

[0137] The lifting vehicle's 8th axle is attached to the barge, which is 11m long. 货驳 =2200t; the tide level of the Maritime Safety Administration at 12:34 is 235cm.

[0138] Ap 吃水 =D 型深 -(H 码头 -H 潮位 )=10.2-(8.15-2.35)=4.4m;

[0139] The corresponding displacement slope a = 2.299 / 24029.3; the corresponding displacement slope a represents the displacement weight w corresponding to the draft of the upper barge. 排总 With Ap 吃水 The relationship between the two forms a rising and falling curve, which is obtained when Ap is obtained. 吃水 Afterwards, w can be obtained from the sinking and floating curve. 排总 ;

[0140] The displacement weight corresponding to the draft of the barge (w) 排总 =Ap 吃水 / a=4.4 / (2.299 / 24029.3)=45989.1;

[0141] Ballast water volume W required for the corresponding draft of the barge 压载水 =W排总 -b-W 货驳 = 45989.1 - 25000 - 2200 = 18789.1;

[0142] F is determined according to the symmetry and torque balance principle formula W1 , F W2 , L3 and L4, and then the ballast water distribution result of the current step of the up-boarding barge is obtained;

[0143] Namely, the following calculation of F W1 , F W2 , L3 and L4 is adopted;

[0144] F1*L1+F W1 *L3 = F2*L2+F W2 *L4; namely, 2200*L1+F W1 *L3 = 0+F W2 *L4; L1 is determined according to the center of gravity of the bow part of the up-boarding barge and the lifting force vehicle and the center of the up-boarding barge;

[0145] W 压载水 = F W1 +F W2 ; namely, 18789.1 = F W1 +F W2 ;

[0146] W 货驳 = F1+F2; namely, 2200 = 2200+0.

[0147] F W1 , F W2 , L3 and L4 of the 3rd step to the 11th step are calculated in the above manner, the calculation principle is the same, and then the ballast water distribution result of the up-boarding barge at each step is obtained. According to the ballast water distribution result at each step, the ballast of the up-boarding barge is adjusted in S3.

[0148] S3, the up-boarding operation scheme is executed: the 0th step to the Nth step are automatically executed according to the up-boarding operation scheme, when the 0th step is executed: the ballast water of the up-boarding barge is adjusted according to the ballast water distribution result of the up-boarding barge so that the deck surface of the up-boarding barge and the wharf surface are flush; when the 1st step is executed: the floating body is up-boarded by using the lifting force vehicle at the bottom of the floating body according to the operation time and the step operation time of the 1st step, and the ballast water of the up-boarding barge is adjusted according to the step operation time of each step and the ballast water distribution result of the up-boarding barge; when the 2nd step to the Nth step are executed: the floating body is up-boarded by using the lifting force vehicle at the bottom of the floating body according to the step operation time of each step, and the ballast water of the up-boarding barge is adjusted according to the step operation time of each step and the ballast water distribution result of the up-boarding barge;

[0149] In step S3, after each step is executed, it is judged whether the stability of the barge, the trim and the heeling of the deck of the barge, the deflection of the barge, the bending moment and the shear force of the barge meet the control requirements, and whether the distribution result of the ballast water of the barge meets the barge operation scheme. If yes, the next step is executed. If not, the ballast water of the barge is adjusted according to the current barge operation scheme.

[0150] S4, after the execution of the Nth step is completed, the intelligent ballast adjustment of the barge is completed.

[0151] The intelligent ballast adjustment method of the buoyant body barge described in the embodiment automatically calculates the barge operation scheme of the buoyant body according to the calculation length, the calculation step d, the operation time, the operation time length and the information of the buoyant body, then automatically executes the 0th step to the Nth step according to the barge operation scheme, and adjusts the ballast water of the barge according to each step of the barge operation scheme. It is automatically executed continuously according to each step of the barge operation scheme after the barge operation scheme of all steps is automatically calculated. It has less calculation amount and continuous process. The main point is to control the ballast water of the barge. The control is more intuitive, and the period of the barge is shortened.

[0152] Embodiment 2

[0153] An intelligent ballast adjustment system of a buoyant body barge, as shown in Figure 4 for executing the intelligent ballast adjustment method of the buoyant body barge described in embodiment 1, comprising a monitoring module, a barge ballast adjustment module, a ballast calculation module and a hydraulic valve control system;

[0154] The ballast calculation module is used to generate the barge operation scheme. The way of generating the barge operation scheme is step S2 in embodiment 1.

[0155] The monitoring module collects the bending moment, the shear force and the deflection data of the barge during the barge operation, and the ballast water amount of each ballast tank of the barge, and compares the bending moment, the shear force and the deflection data of the barge with the safety set value respectively. The bending moment and the shear force are calculated. The deflection is measured. The safety set value is the safety boundary value of the barge in the design.

[0156] Specifically, the monitoring module includes the four-corner draft measurement of the barge, the ballast tank liquid level telemetry and the deflection measurement.

[0157] As shown in Figure 12 The four-corner draft of the corners of the bow and the stern of the barge is arranged, and the four-corner draft of the middle part of the barge is arranged. The four-corner draft of the corners is as shown in Figure 13As shown, the sensor junction box is connected to the sensor through the sensor random cable, the sensor is connected to the ball valve through the mounting flange, the ball valve is connected to the air pipe and the sea stop valve through the tee, the sea stop valve is connected to the side pipe through the single-sided seat plate flange, and the side pipe is connected to the outside through the empty cabin. The empty cabin is not used for ballast, and the pressure is stabilized through the air pipe. The central four-corner draft is as shown in Figure 14 As shown, the sensor junction box, sensor random cable, sensor, mounting flange, ball valve, sea stop valve, single-sided seat plate flange, inclined tee, and side pipe are connected. The connection of the sensor junction box, sensor random cable, sensor, mounting flange, ball valve is the same as the four-corner draft at the corner, the ball valve is directly connected to the sea stop valve, the sea stop valve is connected to the inclined tee through the single-sided seat plate flange, the inclined tee is connected to the side pipe, and the side pipe is connected to the outside through the ballast tank.

[0158] Four-corner draft explanation:

[0159] 1. Basic principle: Arrange the sea pipeline at the bow, amidships, and stern of the left and right sides of the upper barge, respectively. Set the piezoelectric sensor behind the pipeline. Measure the water depth pressure. Convert the corresponding pressure value in the system to the corresponding draft depth. Obtain the four-corner draft value. Calculate the longitudinal and transverse inclination angle of the upper barge. Monitor the change of the floating state of the upper barge.

[0160] 2. Feature point: Set the sea stop valve to close the communication with seawater and facilitate cleaning and maintenance when the air pipe is blocked.

[0161] A separate ball valve is arranged in front of the sensor to facilitate maintenance and replacement of the sensor.

[0162] 3. Set the blowing function: The sea pipeline at the bow (central four-corner draft) is long and easy to grow oysters and backfill silt. Set the blowing function. When blocked, use high-pressure gas pulse to pass through the pipe to reduce pipe maintenance and improve measurement accuracy. That is, the inclined tee is inclined to the compressed air. The compressed air is suddenly added to form a pulse to flush the pipeline and clean the debris.

[0163] Ballast tank liquid level remote measurement as shown in Figure 12 and Figure 15 As shown, the measurement box is arranged at the four corners, and the measurement box is connected to the atmosphere. The sensor is arranged in the measurement box, and the sensor is connected to each ballast tank through a copper pipe. As shown in Figure 15 As shown, one end of the copper pipe is connected to the sensor in the measurement box, and the other end is connected to the collet ball valve. The collet ball valve is connected to the reducing adapter, and the reducing adapter enters the inside of the ballast tank through the depth pipe and extends to the bottom of the ballast tank.

[0164] Liquid level remote measurement explanation:

[0165] 1. Basic principle: use copper pipe to set measuring port in each ballast tank of the upper barge, form a back pressure by blowing gas into the copper pipe, the sensor measures the back pressure value, and the system converts the back pressure value into the corresponding liquid level height and capacity, so as to display the liquid level height and capacity value of the cabin to the operator.

[0166] 2. Feature point: use the blowing measurement principle, the sensor is arranged in the top measuring box, the sensor uses the good environment, which improves the service life and is convenient for replacement and debugging.

[0167] It is provided with a collet type ball valve, a check valve and a drain pipe, which is convenient for maintenance, prevents the ballast tank from backfilling water, and can drain impurities in time.

[0168] 3. Friendly operation interface: can display measurement data value, cabin proportion, visual cabin diagram and 3D liquid level display in real time.

[0169] 4. External interface: can transmit data to the matching system in real time to calculate the stability, use strength and shear force of the upper barge.

[0170] The deflection measurement is shown in FIGS. Figure 12 and Figure 16 The measuring pipes are arranged longitudinally in the longitudinal pipe group, and the measuring pipes are connected to each other. One row of measuring pipes is arranged on the left and right sides of the longitudinal pipe group of the upper barge. The magnetic displacement sensor is arranged in the measuring pipe, that is, the deflection measurement is measured by the magnetic displacement sensor. The sensor accuracy is ≤0.05% FS, and the measurement result can be referred to Figure 17 .

[0171] Deflection measurement arrangement features:

[0172] 1. Different arrangement positions. Arranged near the strong frame, longitudinal bulkhead and transverse bulkhead. Arranged on the bottom plate of the upper barge.

[0173] 2. Different measuring pipe structure forms. Composed of 9 single measuring pipes, each measuring pipe is provided with a gas inlet, left and right flange interfaces, an injection port and a valve, a water outlet and a valve, and a top part that can be detached to facilitate installation and removal of the sensor.

[0174] 3. Different connecting pipe structure forms. The connecting pipe is composed of steel pipes, and a plurality of metal wave expansion joints are arranged in the middle, which is more durable and can withstand higher pressure. Arranged at the bottom position, more convenient for maintenance.

[0175] 4. Different sensors. Magnetic liquid level sensor is used, which has a floating ball and is more durable.

[0176] 5. Main measurement parameter is liquid level, which is more intuitive and accurate.

[0177] 6. With the outer transparent hose, the liquid level can be directly observed.

[0178] The reason for deflection measurement design:

[0179] 1. The deflection deformation of the immersed pipe (floating body) is controlled within the range of cracking of the immersed pipe. The deflection deformation of the ship body needs to be monitored and controlled to prevent the deformation from exceeding the control range. 2. The ship body itself needs to be monitored for deformation during the operation of the semi-submersible barge. 3. The magnetic liquid level sensor has higher measurement accuracy, and the sensor accuracy is <0.05% FS. 4. The measurement of liquid level is more sensitive than the measurement of water column pressure, with high sensitivity. 5. The semi-submersible barge is a longitudinal frame type, and the measuring pipe is placed near the strong frame, longitudinal bulkhead and transverse bulkhead. The accuracy of synchronous deformation of the deck and the bottom plate is higher. 6. The deflection deformation of the semi-submersible barge is related to the bending moment calculation and shear force calculation of the semi-submersible barge. By monitoring the deflection deformation of the semi-submersible barge, the stress condition of the ship body can be further obtained. 7. The measuring pipe is provided with a liquid filling and discharging port, which can adjust the measurement range in the case of serious inclination of the semi-submersible barge. 8. A transparent hose is provided to observe the liquid level of the measuring pipe, which is convenient for calibrating the sensor and checking the device failure. 9. Steel pipe is used, which has long service life and is more stable. 10. The connecting pipe is provided with a metal bellows expansion joint to consider the influence of ship body deflection change on the pipe and adapt to various working conditions.

[0180] The ballast adjustment module of the semi-submersible barge adjusts the ballast water according to the operation scheme of the semi-submersible barge calculated by the monitoring module and the ballast calculation module, and automatically controls the adjustment of the ballast water through a hydraulic valve control system. The hydraulic valve control system is matched with the pipe layout, and the specific arrangement is as follows:

[0181] As shown in Figure 10 and Figure 11 , four dry pump cabins are arranged on each side, and the pump cabins are uniformly distributed along the length of the ship. The pump cabin is arranged with ballast pump group, valve box, etc., and the pump cabins are communicated through longitudinal and transverse pipes. Each pump has a discharge pressure of about 10m, and the discharge capacity is about 3000m 3 / h, and there are 8 pumps in total.

[0182] The ballast longitudinal main pipe is longitudinally arranged in the 2 longitudinal pipes, and the longitudinal pipe is provided with front and rear separate isolation valves. The ballast longitudinal main pipe is made of PE material, and the outer diameter and wall thickness are The design pressure is 2.5bar, and the design pressure of the ballast scanning cabin pipe is 0.17bar. Two transverse branch pipes are arranged transversely in the transverse pipe, and left and right separate isolation valves are arranged. The valve cabin is arranged at the bow, and the four cabin control valves are arranged in the valve cabin. Eight low sea bottom doors, eight transverse outlet ports, four high sea bottom doors and one middle sea bottom door are arranged. As shown in Figure 11As shown, each ballast tank is connected with the longitudinal main pipe through the ballast tank water inlet and outlet mechanism, and the longitudinal main pipe is communicated with the eight low-position sea bottom doors through eight main pipe water inlet and outlet mechanisms, and is communicated with the outside. The ballast tank water inlet and outlet mechanism and the main pipe water inlet and outlet mechanism are both provided with valve control, and can be automatically controlled.

[0183] The valve control performance of the hydraulic valve control system: remote computer mouse operation. Manual mode, single valve switch can be controlled. Automatic mode, multiple valves can be controlled simultaneously. On-site operation valve control cabinet controls the valve. Valve: DN125~DN800 butterfly valve; drive head: imported from Germany Pleiger electro-hydraulic drive head. Proportional valve, opening adjustable, single valve full opening time is about 1min. The sea bottom door and the exhaust port can be freely filled with water at the same time.

[0184] If one of the bending moment, shear force and deflection of the barge exceeds the safety setting value, the buoyancy body stops barge loading, and then the automatic control of the ballast water of the barge loading module is switched to manual operation intervention, and after the intervention, the barge loading scheme is regenerated by the ballast calculation module, and then the manual operation is switched to the automatic control of the ballast water, and the buoyancy body continues to load.

[0185] The intelligent ballast system of the buoyancy body loading described in the embodiment can quickly and accurately calculate the buoyancy body loading scheme at each step through the ballast calculation module, and can safely and efficiently execute the loading scheme at each step through the cooperation of the monitoring module, the barge loading module and the hydraulic valve control system.

[0186] The above only describes the preferred embodiment of the present application, and does not limit the present application. Any modification, equivalent replacement and improvement within the spirit and principle of the present application should be included in the protection scope of the present application.
