Particularly, before drawn water in multi-chamber barrel-shaped basis sedimentation or water filling floating, centrifugal pump is carried out vacuum drainage (as top description in conjunction with Fig. 2), afterwards, startup is to the control operation of the draw water sinking or the water filling floating on multi-chamber barrel-shaped basis, when sinking control, because the water in the outside extraction barrel base, the inside of barrel base is negative pressure state, and barrel base externally pressure effect continues down to sink; And when floating, the barrel base pressure inside is barotropic state, barrel base floating gradually under the effect of internal positive pressure power.In the process of whole sinking or floating, displacement transducer, angular transducer and vacuum meter are to the actual submergence depth or the floating height on multi-chamber barrel-shaped basis, actual angle of inclination and vacuum detect in real time and send signal to control module, control module is with actual submergence depth or floating height, actual angle of inclination and default submergence depth or floating height and corresponding 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 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 on each pipeline showed that basically identical illustrates that then multi-chamber barrel-shaped basis is steadily sinking or come-up; When actual submergence depth or floating height equal default submergence depth or floating height, stop to sink or floating; The vacuum meter that is connected with each chamber of barrel base detects the vacuum in each chamber in barrel base sinking or the floating process, if the interior vacuum unanimity of each chamber that each vacuum meter is shown, illustrate that barrel base is sinking or floating reposefully, if barrel base sinks down into predetermined depth or floating to preset height, then the vacuum in each chamber also reaches the maximum limit of sinking or the minimum limit value of floating (this minimum limit value is closely near atmospheric pressure value).
Owing to may there are differences between the degree of depth that predetermined depth or height and multi-chamber barrel-shaped basis are controlled by sinking or floating control can be sunk or the height of floating.Therefore, according to the difference condition between aforementioned actual grade and predetermined depth or actual height and the preset height, selectively, control method according to sinking/floating of the present invention can further include additional step (also can be configured to carry out following corresponding operation according to control device of the present invention): if just do not keep constant for a long time when the submergence depth of barrel base or floating height reach its predetermined depth or preset height, (this maximum limit can determine 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 set 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 by control device.If through overregulating, vacuum in each chamber still can not the value of reaching capacity and the displacement of barrel base sinking or floating no longer change (at this moment, it is constant that the vacuum of vacuum meter keeps once more), then explanation has reached the displacement limits of sinking or floating, at this moment, draw water for again multi-chamber barrel-shaped basis or water filling can't make it continue to sink or floating, at this moment only need stop to sink or floating control, make the barrel base that does not sink fully sink fully or it be hung the water surface to getting final product by boom hoisting by pouring weight.
In addition, detected each parameter (displacement, flow, submergence depth or floating height, vacuum etc.) can be presented on the display unit in real time in whole sinking or floating control, 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 sinking or floating control etc.
Based on above-mentioned operating principle, below in conjunction with Fig. 3 and Fig. 4 the preferred embodiment of the control method of the sinking on multi-chamber barrel-shaped basis of the present invention, floating is described, be to be understood that, preferred embodiment described herein only is used for description and interpretation 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 whole sinking or 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 by 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 described 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.By 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 vacuum in each chamber by being arranged on vacuum meter 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, vacuum meter herein 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 constructing in the uniform zone of density, beach bottom surface, can do corresponding improvement to the control device among the present invention, according to 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 to carry out the automatic leveling step on multi-chamber barrel-shaped basis, can by 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 described 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, finish the sinking on multi-chamber barrel-shaped basis.
In addition, though it is not shown in Figure 3, but in practice, owing to wait to estimate according to actual conditions such as himself height or practical experience by the default multi-chamber barrel-shaped immerge degree of depth of step S101 and establish, in the control of sinking, may exist by can't make situation that barrel base sinks (promptly to extracardiac pumping, submergence depth no longer changes and the sinking fully of in fact multi-chamber barrel-shaped basis), in this case, vacuum in the maximum limit when vacuum in detected each chamber does not reach, each chamber keeps constant for a long time.Therefore, selectively, the control method according to multi-chamber barrel-shaped immerge/floating of the present invention may further include additional step: can make the vacuum in each chamber reach its maximum limit (even barrel base sinks down into predetermined depth) by 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 of the control method of multi-chamber barrel-shaped basic floating according to the preferred embodiment of the invention.It specifically may further comprise the steps:
Step S201 sets the preset height H that multi-chamber barrel-shaped basis needs floating
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 before floating is carried out in water filling, to carrying out the vacuum drainage by pipeline with the centrifugal pump that each chamber of multi-chamber barrel-shaped basis is communicated with, makes centrifugal pump be in the water filling state.
Step S203 carries out in the process of floating in water filling in each chamber of multi-chamber barrel-shaped basis, utilizes sensor element to detect the actual height h of multi-chamber barrel-shaped basic floating
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.By actual floating height and the actual angle of inclination of multi-chamber barrel-shaped basis in the floating 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 S204 carries out in the process of floating in water filling in each chamber of multi-chamber barrel-shaped basis, detects vacuum in each chamber by being arranged on vacuum meter on the multi-chamber barrel-shaped basis.In like manner,, illustrate that barrel base is floating reposefully, and when vacuum reaches minimum limit value (near atmospheric pressure value) if the vacuum that detects in each chamber is consistent, illustrate barrel base floating to preset height.
Step S205 carries out in the process of floating 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 height h of the actual floating in multi-chamber barrel-shaped basis that 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 to carry out the automatic leveling step on multi-chamber barrel-shaped basis, can by 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 described multi-chamber barrel-shaped basis of inclination, thereby make this multi-chamber barrel-shaped basis floating reposefully; And as detected actual grade h
2Equal described predetermined depth H
2The time, then stop the floating control on multi-chamber barrel-shaped basis.
Similarly, though in Fig. 3, do not illustrate, but, selectively, control method according to multi-chamber barrel-shaped basic floating of the present invention also can comprise 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 sinking on multi-chamber barrel-shaped basis or control device of floating controlled, 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
