Description
technical field
The utility model relates to a kind of desilting system of excavated basin, specifically relates to a kind ofly penetrate the pipe water outlet by the speedometer Based Intelligent Control and silt is suspended push ahead and utilize the basin moisture regain to wash away the system of suspension bed sediment.
Background technology
At present, for China's inland excavated-in basin present situation, a lot of scholars have done relevant research, because excavated basin mouth door place exists backflow and Turbid Density Flow or due to tidal effect of Hekou Area etc., basin inevitably can produce alluvial, and this is also the problem that designing unit, applying unit generally are concerned about.On the basis of flume experiment, the bound fraction theory analysis, studied excavated basin the Sediment Siltation problem reason and the alluvial characteristic.Result shows: sand content distributes and has certain rule, and mouthful door place siltation volume is larger, and sediment grain size is thicker, and the inner siltation volume of basin is less, and particle diameter is thinner.When silt content of river is larger, in basin, alluvial is more serious, making harbour of ship brought to very large impact, and the maintenance workload of basin and expense larger, so the alluvial that the desilting system of a kind of excavated basin of utility model reduces this form basin mouth door place is very necessary.
The utility model content
The purpose of this utility model is to have overcome deficiency of the prior art, provides a kind of and has penetrated the pipe water outlet by the speedometer Based Intelligent Control and silt is suspended push ahead and utilize the basin moisture regain to wash away the system of suspension bed sediment.
In order to solve the problems of the technologies described above, the utility model is to be achieved through the following technical solutions:
The utility model is a kind of desilting system of excavated basin, effluent road 1, and excavated basin 2, current tachymeter 3, jet pipe 4, main 5, high-voltage tube 6, middle pressure pipe 7, low-voltage tube 8, several parts such as pump house 9 form.It is characterized in that, excavated basin 2 import departments arrange current tachymeter 3, main 5 arranges 4, on main 5, along the even interval of pipe range, arranges jet pipe 4, and jet pipe 4 becomes miter angle with main 5 tendency basin imports with horizontal plane, high-voltage tube 6 is in import department, two middle pressure pipes 7 are in the middle of basin, and low-voltage tube 8 is at the basin end, and high-voltage tube 6, middle pressure pipe 7, low-voltage tube 8 are connected with main 5 use flange respectively, high-voltage tube 6, middle pressure pipe 7, low-voltage tube 8 are drawn by pump house 9, in order to control hydraulic pressure.
Described main 5 lateral arrangement, closed at both ends.
Described current tachymeter 3 is placed on the centre of basin import department.
The utility model is a kind of desilting system of excavated basin, in basin import department, the current tachymeter is set, according to the hydraulic research theory, the speed of taking husky ability and current of water is closely related, when flow rate of water flow is reduced to a certain value, silt will be sunk to depositing by suspended state, therefore when flow rate of water flow is reduced to this value, intelligence system can be controlled pump house by each pressure pipeline water delivery, due to larger at basin import department siltation volume, sediment grain size is thicker, therefore high-voltage tube is set.The inner siltation volume of basin is less, and particle diameter is thinner, therefore along basin, middle pressure pipe and low-voltage tube are set in basin inside.Current enter each main by pressure pipeline, and penetrated by jet pipe, make silt again become suspended state, when current run into the moisture regain of basin end wall, take silt out of basin, jet pipe also can become silt the basin of going out of step form simultaneously, finally by main flow, is taken away, and dual hydraulic action reaches the purpose of basin desilting.
Compared with prior art, the beneficial effects of the utility model are: this utility model is taken away silt by jet impulse and current moisture regain effect, thereby reaches the purpose of comprehensive desilting in basin, and structural configuration is simple, easy construction, and easy care, easily promote.
The accompanying drawing explanation
Fig. 1 is the desilting system layout plan of a kind of excavated basin of the utility model
Fig. 2 is the arrangement diagram of the utility model pressure pipeline
Wherein: 1 is river course, and 2 is excavated basin, and 3 is the current tachymeter, and 4 is jet pipe, and 5 is main, and 6 is high-voltage tube, and 7 is middle pressure pipe, and 8 is low-voltage tube, and 9 is pump house.
The specific embodiment
1 further illustrate the utility model by reference to the accompanying drawings.
As shown in Figure 1, the utility model comprises river course (1), excavated basin (2), current tachymeter (3), jet pipe (4), main (5), high-voltage tube (6), middle pressure pipe (7), low-voltage tube (8), pump house (9).Excavated basin (2) import department arranges current tachymeter (3), main (5) arranges 4, upper along the even interval of pipe range layout jet pipe (4) at main (5), jet pipe (4) becomes miter angle with the import of main (5) tendency basin with horizontal plane, high-voltage tube (6) is in import department, two middle pressure pipes (7) are in the middle of basin, low-voltage tube (8) is at the basin end, high-voltage tube (6), middle pressure pipe (7), low-voltage tube (8) are connected with flange with main (5) respectively, and high-voltage tube (6), middle pressure pipe (7), low-voltage tube (8) are drawn by pump house (9).Described main (5) lateral arrangement, closed at both ends.Described current tachymeter (3) is placed on the centre of basin import department.In order to control hydraulic pressure.Surveying the flow rate of water flow Based Intelligent Control by tachymeter penetrates the pipe water outlet and silt is suspended push ahead and utilize the basin moisture regain to wash away the system of suspension bed sediment.
Concrete implementation step is: when current flow into excavated basin 2 import department along river course 1, with current tachymeter 3, measure water velocity.When water velocity is reduced to certain value, silt starts by suspension the alluvial of sinking.Now pump house 9 starts to each pressure pipeline water delivery, current enter low-voltage tube 8 and are penetrated by the superincumbent jet pipe 4 across strike basin import miter angles of layout, thinner silt is pushed ahead or is become suspension under water slug, and same current enter middle pressure pipe 7 and are penetrated by the superincumbent jet pipe 4 across strike basin import miter angles of layout, make silt continue forward to advance or become suspension, last current enter high-voltage tube 6 and, by arranging that superincumbent jet pipe 4 across strike basin import miter angles penetrate, make silt enter main stem or one-tenth suspension.High-voltage tube 6, middle pressure pipe 7, low-voltage tube 8 are opened simultaneously, whole process is carried out simultaneously, so the propelling of silt can regard the propelling of stepped-style as, and now the silt of suspension can be brought main stem into by the current of moisture regain, be flushed away, dual hydraulic action reaches the purpose of desilting.
