The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
Shown in Fig. 6, the present embodiment desilting suction nozzle adopts the design of herringbone dual channel, the suction inlet opposite direction of two runners, two runners of this suction nozzle are independent of one another, cross section of fluid channel Ji Cong intersection increases downwards gradually, and becoming rectangle cross section from circular cross-section, suction inlet direction becomes and is parallel to desilting bottom surface.Owing to being provided with two runners independent of each other, the turbulent flow of having avoided the liquid collision of different directions to cause when two-way suction is become silted up, has improved the efficiency of desilting, has also reduced the structural damage of suction nozzle own.
Particularly, with reference to diagram, the present embodiment desilting suction nozzle comprises that upper port converges to same converting pipe 9, square rotatable baffle plate (1) is established at middle part, the first flow 21 of bottom suction inlet 7 directions towards the opposite and the second runner 22, described first flow 21 and the second runner 22 are combined to form " people " character form structure, and the open end of two runner bottom suction inlets 7 is vertical with desilting substrate, also be that suction inlet 7 opening directions are parallel to desilting bottom surface, the shape of cross section of suction inlet 7 is quadrangle, this shape can increase the contact area of suction inlet 7 and Mud Layer, can high efficiency desilting not destroy again desilting underlying structure.
According to the requirement of desilting substrate material protection, by adjusting the area of suction inlet 7, can reach the object that regulates suction inlet 7 place's suction and fluid velocity, suction and fluid velocity are met and can not start the materials such as substrate rubble, reach the object at the bottom of protecting group.By the priming speed of experimental test desilting underlying structure material, select applicable suction inlet area and suction inlet speed, make suction nozzle high efficiency desilting not destroy again desilting substructure.
The converting pipe 9 that desilting suction nozzle connects outside dredging tube by its top starts, being converted to cross section is downwards tetragonal pipe, the cross section that is the top of first flow 21 and the second runner 22 is quadrangle, the middle part of two runners is divided into two arms, and cross section constantly expands until parallel desilting substrate, two arms are first flow 21 and the second runner 22, the top of first flow 21 and the second runner 22 is to separate by baffle plate 1, realize the independence of two runners, baffle plate 1 Fig. 1 section is vertical, baffle plate 1 bottom is provided with rotating shaft, baffle plate 1 can rotate around the shaft, so that first flow 21 or the second runner 22 are blocked, when baffle plate 1 correspondence reaches left and right maximum angle or centre position, can realize respectively right side, left side or two-directional dredging.
In order further to improve the desilting efficiency data of desilting suction nozzle, the cross sectional area of first flow 21 and the second runner 22 is increased to suction inlet 7 places gradually by two runner middle parts; Because first flow 21 and the second runner 22 are combined to form " people " character form structure, so top board and the base plate of suction inlets 7 are formed at first flow 21 and the second runner 22 bottoms, be respectively arc.
The rectangular tube that desilting suction nozzle top is converted to its middle part from pipe is realized by a joint converting pipe (9), converting pipe (9) is connected between outside dredging tube and two runners, one end opening of this converting pipe (9) is circular, be connected with outside dredging tube, other end opening is rectangle, is connected with the second runner 22 with first flow 21; Converting pipe (9) is comprised of four triangle roll bendings 11 and four set squares 10, the plate that triangle roll bending 11 is arc for the surface that is bent to form by triangular plate, and the base of triangle roll bending 11 is arc, is connected with outside dredging tube; The base of four set squares 10 is connected with the four edges of the quadrangle pipe of the second runner 22 intersections with first flow 21, other two limits of set square 10 are connected with triangle roll bending 11 hypotenuses, so far complete the transition to quadrangular section by circular cross-section, from pipe, be transitioned into first flow 21 and the second runner 22.
As can be seen from the above embodiments, the utility model is by being provided with toward each other independently two runners, can effectively avoid inhaling the turbulent phenomenon while becoming silted up, and can high-efficient cleaning can protect the structure of desilting bottom surface again except mud; The shape design of suction inlet meets and can not destroy again desilting polycrystalline substance with enough speed desiltings; Suction nozzle can carry out desilting in more loose bottom surface, and desilting precision improves; In addition, the horizontally-guided plate resistance gear suction nozzle of suction inlet top is drawn the less mud of top density, has improved desilting efficiency data.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvement and replacement, these improvement and replacement also should be considered as protection domain of the present utility model.
