Portion's connection；Based on above-mentioned design, the volume of hollow cavity need not be excessive in hollow shaft, and spray nozzle can be allowed to have enough depth can be with
It is fixed on hollow shaft side wall, certainly, the difference in height of the distance from top hollow shaft side wall of spray nozzle should not exceed first after installation
The height of helical blade or the second helical blade.
Confined space inside hollow shaft can guarantee that the pressure of its interior water flow will not reduce, and pass through sealing bearing and high pressure
Water pump connection guarantees to remain to normally connect with high-pressure hydraulic pump when hollow shaft rotation.When external water stream is passed through first by high-pressure hydraulic pump
After pipeline introduces hollow shaft, it can be realized by the spray nozzle being mounted on hollow shaft side wall to the first helical blade and the second spiral shell
The cleaning of vane piece.
Please refer to Fig. 3 the embodiment described two.
The design of pumping outlet is optimized in the present embodiment.It is specific as follows:
The pumping outlet 9, which is located on 5 middle part of the first side plate and the pumping outlet 9, is covered with diagrid plate 10；The lattice
Sieve plate 10 include: can be affixed with 9 edge of pumping outlet diagrid ring 11, the horizontal grating 12 that is connected across in the diagrid ring 11
With the vertical grating 13 for being vertically arranged and being connected across in the diagrid ring 11 with the horizontal grating 12.
In the present embodiment, the side of relatively close hollow shaft is equipped with diagrid plate 10 at the pumping outlet.
The diagrid plate, can break up mud, in order to which it is entered under the action of submersible sewage pump by pumping outlet
The process of second pipeline and exterior line is more smooth.
Its principle is:
Horizontal grating and vertical grating on diagrid plate can be cut to via the mud block of diagrid plate, be prevented in pumping outlet
Place forms biggish mud block and causes the blocking of pumping outlet.
Optionally, it can be equipped with curved sieve 121 on the horizontal grating and vertical grating, once starting submersible sewage pump, mud
By under the pressure that submersible sewage pump provides, during mud is attracted and enters the second pipeline by pumping outlet, curved 121 energy of sieve
It is enough that more preferably cutting effect is played to mud block.
Please refer to Fig. 4 the embodiment described three.
The design of wiper ring is provided in the present embodiment.It is specific as follows:
Further include: wiper ring 14；Diagrid duct 15 is distributed with to annular array on the diagrid plate 10；The wiper ring 14
Whole structure in a ring and it is set in 10 outer wall of diagrid plate；14 inner hollow of wiper ring and thereon relatively close diagrid
The cleaning protrusion 16 being connected to inside wiper ring 14 is distributed with to annular array on 10 side wall of plate；The raised 16 proper datives of the cleaning
Sieve pore road 15 corresponds；10 side wall of diagrid plate is relatively distant from the wiper ring 14 equipped with water inlet 17 and the water inlet
17 are connected to by third pipeline with external fluid delivery conduit road；The third pipeline extend along first side plate 5 and with the first side plate 5
It is affixed.
In the present embodiment, the design of wiper ring is also additionally arranged on the pumping outlet, its object is to: it can be by outer
Portion's water flow plaid matching sieve plate is cleaned.
Its specific structure and installation site are as shown above.
The principle is as follows:
Enter water by external fluid delivery conduit pass to flow in hollow wiper ring, then, be protruded out into via cleaning thereon
Diagrid duct on diagrid plate can clean the horizontal grating of its attachment, vertical grating from diagrid duct, to a certain degree
On, it is able to extend the practical dredging duration of diagrid plate, to improve the working efficiency of whole Accrete clearing device.
To fix third pipeline, it is fixed on first side plate in this implementation, the third pipeline is through described
First side plate is connected with external fluid delivery conduit road, and the external fluid delivery conduit road includes: external water supply pump.
It is, of course, also possible to which the third pipeline is connected by tee tube with external high pressure water pump with first pipeline.
Please refer to the example IV that Fig. 5 is stated.
The design of attached fan is provided in the present embodiment.It is specific as follows:
In any preferred embodiment, the center of diagrid plate 10 is additionally provided with connection pillar 18 and the connection pillar 18
Attached fan 19 is connected with by bearing；The attached fan 19 includes: the attached set connected with pillar 18 is connect by sealing bearing
20 and annular array be located at least two flabellums 21 of 20 surrounding of attached set；2 side wall of hollow shaft is equipped in institute
State the positive corresponding and spray nozzle 8 between first helical blade 3 and the second helical blade 4 of attached fan 19.
In the present embodiment, the design of attached fan is additionally arranged in the center of diagrid plate 10, its object is to: attached fan can
Connection pillar rotation around diagrid plate center can be to being attached to its covered horizontal grating of institute during its rotation
It is cut again with mud block on vertical grating, effectively to be cleared up.
The specific structure and installation site of attached fan are as shown above.
In above-mentioned design, independent power supply unit is not configured in attached fan, and the principle of design is, starts submersible sewage pump,
Mud is by under the pressure that submersible sewage pump provides, and during mud is attracted and enters the second pipeline by pumping outlet, mud will not
It is attracted in second pipe quickly, during mud enters, scattered sludge bulking can contact from different angles
Flabellum so that flabellum be driven to have the rotation of certain angle, and then plays and further cuts effect, improves desilting efficiency data.
In the present embodiment, it is not required that attached fan realizes continuous rotation, but touches difference in two flabellum
External force under, can have the rotation of certain angle.
In addition, when the spray nozzle in hollow shaft sprays its water flow inside to flabellum, it is also possible that flabellum generates
The rotation of certain angle can also clear up the mud being attached on diagrid plate via the water flow that flabellum disperses.
It should be understood that
Attached drawing 5 is only used for illustrating the installation site of attached fan, plays the dimension scale with the diagrid plate not by attached
The limitation of Fig. 5, in specific application, the flabellum quantity of attached fan do not require it is more, in order to avoid caused to whole silt dredging process bad
It influences, 2-3 are best；In addition, the width of flabellum does not require wide, the width of not larger than horizontal grating or vertical grating is most
It is good.
Preferably, Fig. 6 and Fig. 6-1 are please referred to, the design that the structure of flabellum is refined is directed in present embodiment.
It is distributed with and multiple prolongs on the side wall of relatively close hollow shaft 2 along 21 normal direction of flabellum on the flabellum 21
The segmentation thorn 23 stretched.
Segmentation thorn designed for: can further prevent mud at diagrid plate, be formed and biggish is not easy to
The mud block passed through.
The segmentation thorn 23 include: the hollow segmentation column 231 affixed with 21 side wall of flabellum and with the segmentation column 231
Matched bur 232；The free end of the segmentation column 231 offers relatively close segmentation column on through-hole and the bur 232
231 one end enters the through-hole；One end that the bur 232 enters segmentation column 231 is equipped with the anti-flake 233 that diameter is greater than through-hole
And spring 234 is socketed on the anti-flake 233；The free end of the spring 234 is supported to the inner bottom wall of the segmentation column 231.
Based on above-mentioned design, when bur 232 receives external pressure, can be moved to close to the direction of the segmentation column 231
It is dynamic；When external pressure removes, bur 232 restores under the action of spring 234 to initial position.
Start submersible sewage pump, mud is attracted in mud by under the pressure that submersible sewage pump provides and enters the second pipe by pumping outlet
