Particularly, drawn water in multi-chamber barrel-shaped basis sedimentation or water filling rise floating before, centrifugal pump is carried out vacuum drainage (like the description of top combination Fig. 2); Afterwards; Drawing water of multi-chamber barrel-shaped basis sunk in startup or water filling plays floating control operation, when sinking control, owing to outwards extract the water in the barrel base; The inside of barrel base is negative pressure state, and barrel base externally pressure effect continues down to sink; And rising when floating, the barrel base pressure inside is barotropic state, and barrel base rises floating under the effect of internal positive pressure power gradually.In a whole sinking or a floating process; Displacement transducer, angular transducer and vacuum meter are to the actual submergence depth on multi-chamber barrel-shaped basis or play floating height, actual angle of inclination and vacuum and detect in real time and send signal to control module; Control module with actual submergence depth play floating height, actual angle of inclination and preset submergence depth or play floating height and accordingly a maximum preset angle of inclination compare; When actual angle of inclination during greater than the maximum preset angle of inclination; Promptly to pipeline that the inclined side on multi-chamber barrel-shaped basis is communicated with on throttling arrangement send the signal of Flow-rate adjustment; Leveling is carried out on multi-chamber barrel-shaped basis, made it to sink reposefully or rise floating; Flow meter provides the discharge in each pipeline in real time; On display unit, show in real time; In addition, when beach bottom surface soil layer property was relatively more even, the flow demonstration basically identical on each pipeline explained that then multi-chamber barrel-shaped basis is steadily sinking or come-up; When actual submergence depth or rise floatingly when highly equaling preset submergence depth or playing floating height, stop to sink or rise floating; The vacuum meter that is connected with each chamber of barrel base detects the barrel base sinking or plays the vacuum in each chamber in the floating process; If the vacuum in each chamber that each vacuum meter showed is consistent; Explain that barrel base is sinking reposefully or rising floating; If barrel base sinks down into predetermined depth or rises and float to preset height, then the vacuum in each chamber also reaches the maximum limit of sinking or plays floating minimum limit value (this minimum limit value is closely near atmospheric pressure value).
Because predetermined depth or height and multi-chamber barrel-shaped basis are through sinking control or play the degree of depth that floating control can sink or rise between the floating height and possibly there are differences.Therefore; According to the difference condition between aforementioned actual grade and predetermined depth or actual height and the preset height; Selectively; Can further include additional step (also can be configured to carry out following corresponding operation) according to a sinking of the present invention/floating control method: just keep constant for a long time if the submergence depth of barrel base perhaps rises to float when highly reaching its predetermined depth or preset height according to control device of the present invention; (this maximum limit can confirm that minimum limit value is near atmospheric pressure value according to the pumping pressure limit value of centrifugal pump to minimum limit value when maximum limit when then the vacuum in each chamber of barrel base this moment does not reach its sinking yet and rising.Under the situation that adopts automaton, can be arranged in advance in the control program of device), at this moment, also there is the possibility that continues to sink or float in barrel base.Regulate the throttling arrangement on (regulating or manual adjustments) and the pipeline that each chamber is communicated with, so that the interior vacuum of each chamber reaches its limiting value through control device.If through overregulating; Vacuum in each chamber still can not the value of reaching capacity and barrel base sink or work a displacement of floating to no longer changing (at this moment; It is constant that the vacuum of vacuum meter keeps once more); Then explanation has reached or the displacement limits of come-up, at this moment, draws water for multi-chamber barrel-shaped basis or water filling can't make it continue to sink or rises floating again; At this moment only need stop to sink or rising floating control, make the barrel base that does not sink fully sink fully or it hung the water surface by pouring weight and get final product by boom hoisting.
In addition; Detected each parameter in a whole sinking or a floating control (displacement, flow, submergence depth or a floating height, vacuum etc.) can be presented on the display unit in real time; So that the operator understand control procedure carry out state and can taking appropriate measures in view of the above; For example, when vacuum keeps constant once more, stop to sink or playing floating control etc.
Based on above-mentioned operating principle; To combine Fig. 3 and Fig. 4 that the sinking on multi-chamber barrel-shaped basis of the present invention, the preferred embodiment of a floating control method are described below; Should be appreciated that preferred embodiment described herein only is used for explanation and explains the present invention, and be not used in qualification the present invention; And the arrangement of following step neither be to the enforcement qualification in proper order of control method of the present invention, because these all dynamically carry out in a whole sinking or a floating control procedure.
Fig. 3 is the schematic flow sheet of the control method of multi-chamber barrel-shaped immerge according to the preferred embodiment of the invention, and it specifically may further comprise the steps:
Step S101 sets multi-chamber barrel-shaped basis and needs the predetermined depth H of sinking
1And its maximum preset tilt angle alpha with respect to the horizontal plane that allows
10Wherein, Because the final purpose of sinking is that multi-chamber barrel-shaped basis is sunk fully; Therefore, the predetermined depth of sinking can be set according to the actual conditions such as height on multi-chamber barrel-shaped basis self, and according to practical experience; In order to keep the beach bottom surface not being damaged in the sinking process, this maximum preset tilt angle alpha
10Should not surpass 1 degree.
Step S102, draw water carry out sedimentation before, to carrying out the vacuum drainage with the centrifugal pump that each chamber of multi-chamber barrel-shaped basis is communicated with, make centrifugal pump be in the state of drawing water through pipeline.
Step S103 carries out in the process of sedimentation at the water that outwards extracts in each chamber of multi-chamber barrel-shaped basis, utilizes sensor element to detect the actual grade h of said multi-chamber barrel-shaped immerge
1And actual angle of inclination α with respect to the horizontal plane
1, sensor element described herein is displacement transducer and angular transducer, certainly, also can adopt other can realize the element of identical function.Through actual submergence depth and the actual angle of inclination of multi-chamber barrel-shaped basis in the sinking process detected in real time, can carry out the control corresponding step according to the contrast of the data and the preset data of real-time detection.
Step S104 carries out in the process of sedimentation at the water that outwards extracts in each chamber of multi-chamber barrel-shaped basis, detects the vacuum in each chamber through the vacuum meter that is arranged on the multi-chamber barrel-shaped basis.As previously mentioned, on the one hand, when barrel base steadily sank, the vacuum in each chamber was consistent; On the other hand, if barrel base sinks down into predetermined depth, then the vacuum in each chamber this moment reaches maximum limit and remains unchanged.Certainly, the vacuum meter here also can be pressure gauge, pressure sensor or other elements.
Step S105 carries out in the process of sedimentation at the water that outwards extracts in each chamber of multi-chamber barrel-shaped basis, preferably, utilizes the flow meter that is arranged on the pipeline that is communicated with each chamber of multi-chamber barrel-shaped basis to detect the discharge that flows through in each pipeline.Under the uniform situation of beach bottom surface density, if the discharge in each pipeline is consistent basically, show that then multi-chamber barrel-shaped basis is sinking reposefully, and if its flow is inconsistent, show that then sinking is not steady.This can be used as the sink reference frame of monitoring of operating personnel, when construct in the uniform zone of density in the beach bottom surface, can do corresponding improvement to the control device among the present invention, based on traffic monitoring the smoothness that sinks is controlled.
Step S106 is to the actual degree of depth h that sinks in the multi-chamber barrel-shaped basis of being detected among the step S103
1And actual angle of inclination α
1With aforesaid predetermined depth H
1And maximum preset tilt angle alpha
10Compare respectively, as actual angle of inclination α
1Greater than the maximum preset tilt angle alpha
10The time; Then need carry out the automatic leveling step on multi-chamber barrel-shaped basis; Can through strengthen with pipeline that higher side cavity is communicated with in discharge and/or the mode of the discharge in the pipeline that reduces to be communicated with side cavity on the low side leveling is carried out on the said multi-chamber barrel-shaped basis of inclination, thereby this multi-chamber barrel-shaped basis can be sunk reposefully; And as detected actual grade h
1Equal predetermined depth H
1The time, then stop the sinking control on multi-chamber barrel-shaped basis, accomplish the sinking on multi-chamber barrel-shaped basis.
In addition; Though not shown in Fig. 3; But in practice, establish, in sinking to controlling, possibly exist through can't make situation that barrel base sinks (promptly to extracardiac pumping owing to wait to estimate according to actual conditions such as himself height or practical experience through the preset multi-chamber barrel-shaped immerge degree of depth of step S101; Submergence depth no longer changes and the sinking fully of in fact multi-chamber barrel-shaped basis); In this case, the maximum limit the when vacuum in detected each chamber does not reach, the vacuum in each chamber keeps constant for a long time.Therefore; Selectively, may further include additional step according to multi-chamber barrel-shaped immerge of the present invention/floating control method: can make the vacuum in each chamber reach its maximum limit (even barrel base sinks down into predetermined depth) through regulating throttling arrangement (as transferring big its opening).If still can't make the vacuum in each chamber reach maximum limit through overregulating throttling arrangement, the control that then can stop to sink utilizes pouring weight to press down or other modes sink to getting final product with barrel base fully.
Fig. 4 is the schematic flow sheet that floating control method is played on multi-chamber barrel-shaped according to the preferred embodiment of the invention basis.It specifically may further comprise the steps:
Step S201 sets multi-chamber barrel-shaped basis and has needed floating preset height H
2And its maximum preset tilt angle alpha with respect to the horizontal plane that allows
20, wherein, preset height is estimated according to the high actual conditions of bucket and is established the maximum preset tilt angle alpha
20Value can be when sinking the maximum preset tilt angle alpha
10Big a little.
Step S202, water filling rise floating before, to carrying out the vacuum drainage with the centrifugal pump that each chamber of multi-chamber barrel-shaped basis is communicated with, make centrifugal pump be in the water filling state through pipeline.
Step S203 rises in the floating process in water filling in each chamber of multi-chamber barrel-shaped basis, utilizes sensor element to detect multi-chamber barrel-shaped basis and plays floating actual height h
2And actual angle of inclination α with respect to the horizontal plane
2, sensor element described herein is displacement transducer and angular transducer, certainly, also can adopt other can realize the element of identical function.Through the reality of multi-chamber barrel-shaped basis in playing floating process being played floating height and actual angle of inclination detects in real time, can be according to the contrast of data and the preset data of real-time detection, execution control corresponding step.
Step S204 rises in the floating process in water filling in each chamber of multi-chamber barrel-shaped basis, detects the vacuum in each chamber through the vacuum meter that is arranged on the multi-chamber barrel-shaped basis.In like manner,, explain that barrel base is floating reposefully, and when vacuum reached minimum limit value (near atmospheric pressure value), it was floating to preset height to explain that barrel base has risen if the vacuum that detects in each chamber is consistent.
Step S205 rises in the floating process in water filling in each chamber of multi-chamber barrel-shaped basis, preferably, utilizes the flow meter that is arranged on the pipeline that is communicated with each chamber of multi-chamber barrel-shaped basis to detect the discharge that flows through in each pipeline.Reason is similar to the description in the sinking control method.
Step S206 is to the actual height h that floats that rises in the multi-chamber barrel-shaped basis of being detected among the step S203
2And actual angle of inclination α
2With aforesaid preset height H
2And maximum preset tilt angle alpha
20Compare respectively, as actual angle of inclination α
2Greater than the maximum preset tilt angle alpha
20The time; Then need carry out the automatic leveling step on multi-chamber barrel-shaped basis; Can through strengthen with pipeline that side cavity on the low side is communicated with in discharge and/or the mode of the discharge in the pipeline that reduces to be communicated with higher side cavity leveling is carried out on the said multi-chamber barrel-shaped basis of inclination, thereby it is floating that this multi-chamber barrel-shaped basis can be risen reposefully; And as detected actual grade h
2Equal said predetermined depth H
2The time, then stop the floating control of rising of multi-chamber barrel-shaped basis.
Likewise; Though in Fig. 3, do not illustrate; But selectively, multi-chamber barrel-shaped basis according to the present invention is played floating control method and also can be comprised additional step: if the vacuum in detected each chamber does not reach minimum limit value (near atmospheric pressure value) but remains unchanged for a long time; Throttling arrangement on then can regulating in the pipeline that is communicated with each chamber (as transferring the opening of big throttling arrangement) is so that barrel base continues come-up.If still can't make the vacuum in each chamber reach atmospheric pressure value through overregulating, then explanation continues water filling has not at this moment had practical significance.Can utilize boom hoisting that barrel base is sling.
In addition; The present invention also provides a kind of and has controlled the sinking on multi-chamber barrel-shaped basis or play floating control device; According to a preferred embodiment of the invention, this device comprises: detecting unit, it comprises again: the actual grade h that is arranged on the multi-chamber barrel-shaped immerge of detection on the multi-chamber barrel-shaped basis
