Abstract
This invention provides a high speed ejector pump under water. It includes pump case with water inlet opening; moving blade arranged in pump case and located lower reach of water inlet opening; nozzle fixed on pump case and has water outlet opening; guiding body arranged between moving blade and nozzle. It has the same axle with moving blade. At least parts of the guiding body extend into nozzle. The inner wall of nozzle and outer wall of guiding body extending into nozzle form a negative pressure space. The ejector pump can absorb water into cavity by external force, after which drives moving blade rotation. The high speed rotation of moving blade makes water enter the negative pressure space and form high speed water bundle. At last, the water bundle ejects out of the water outlet opening in high speed.
Description
Technical field
The present invention relates to a kind of jet pump, particularly a kind of high velocity jet pump that is used under water.
Background technique
Existing jet pump generally includes the pump case with cavity, offer water intake on the described pump case, being provided with in the cavity can be along the moving vane of pump case shaft axis rotation, the motor that output terminal is connected with described moving vane, electric motor starting rear driving moving vane high speed rotating, thereby liquid constantly is sucked into to come along with moving vane rotates together from water intake, under action of centrifugal force, liquid flies away from moving vane and outwards penetrates from water outlet, flows out from discharge tube again.
Motor drives because this jet pump needs independently, and water damages motor thereby the motor room is easy to into, so this kind jet pump is not suitable for being applied on surfboard or the motor boat.

Embodiment
Below in conjunction with accompanying drawing embodiments of the present invention are described in detail:
As depicted in figs. 1 and 2 be used under water high velocity jet pump, this high velocity jet pump can be used on surfboard or the motor boat, it comprises pump case 1, is fixedly installed on the nozzle 2 in pump case 1 downstream, wherein, pump case 1 is a hollow cavity 11, be provided with water intake 111 above pump case 1, described nozzle 2 is connected with described cavity 11.
In the hollow cavity 11 of pump case 1, be provided with moving vane 12, be positioned at the fixed blade 13 in moving vane 12 downstreams, moving vane 12 is shape in the shape of a spiral, as shown in Figure 3, and the distance between the inwall of the blade of moving vane 12 and pump case 1 is very little, moving vane 12 is connected with the output terminal of the motor (not shown) of surfboard or motor boat, thereby provide driving force by this motor, when current enter cavity 11 from water intake 111, moving vane 12 rotates, and the rotation of moving vane 12 makes current come in to form the strong current that rotates to Way out from water intake 111.
For fixing moving vane, can be coaxial when making it to rotate with pump case 1, and produce resistance for as far as possible moving vane 12, be provided with mandrel component 3 in the cavity 11 of pump case 1, this mandrel component 3 comprises shaft axis and described moving vane 12 shaft center line coincide the stainless steel mandrel 31 that is provided with, the bearing 32,33 that is used for fixing described mandrel 31.Described moving vane 12 is set on this mandrel component 3.
Be provided with fixed blade 13 in the downstream of moving vane 12, as shown in Figure 4, this fixed blade 13 be fixed in the cavity 11 and with pump case 1 coaxial setting, fixed blade 12 has a plurality of blades 131,131 of adjacent vanes form one and cut apart guide space 132.Thus, fixed blade 13 is cut apart the current of the rotation that moving vane 12 is brought into, and the angle of the blade 131 of fixed blade 13 is further strengthened the rotating force of current.
Shown in Figure 6 is the structural representation of described nozzle 2, these nozzle 2 flares, and offer water outlet 21 at nozzle 2.
Also be provided with deflector 14 in described fixed blade 13 downstreams, as shown in Figure 5, tapered and described deflector 14 underparts of described deflector 14 extend in the nozzle 2.Thereby between the outer wall of the inwall of nozzle 2 and deflector 14, form a negative pressure space 15.Deflector 14 stops the too fast mixing of rotation water column that enters in the nozzle 2, produces mixed flow in described negative pressure space 15.The strength of going out of the powerful rotary water current that nozzle 2 will get off from deflector 14 finally is brought together and ejects.
In order to play better sealing effect, on described pump case 1 inwall, also be set with stainless steel coil 5.
For the controlled water flow direction, this jet pump also comprises and is arranged on the direction control mechanism 4 that described nozzle 2 underparts are connected with described water outlet 21.This direction control mechanism 4 comprises and described nozzle 2 underparts socket-connect the above-below direction control valve 41 that can carry out up-down adjustment, the left and right directions control valve 42 that is set in the carried out left and right adjusting on the described above-below direction control valve 41.Described direction control mechanism 4 can carry out direction adjusting up and down, shown in accompanying drawing 8 and accompanying drawing 9.
Working principle of the present utility model is as follows:
Under effect by an external force, moving vane 12 high speed rotating are incorporated into current in the described cavity 11 from water intake 111, under the high speed rotating of moving vane 12, current are high speed rotating under the drive of blade also, the blade 131 of fixed blade 13 is cut apart the current of rotation, make current further strengthen at each rotating force of cutting apart guide space 132, deflector 14 makes current be rotated in negative pressure space 15 by certain camber line, thereby make the strength of going out of powerful rotary water current be brought together by the outlet of ejectisome 2 and eject, the can regulate direction control mechanism 4 as required, direction control mechanism 4 can be adjusted on the left right or down, thereby change water outlet direction and impulse force, thereby to different direction running the time, provide reaction thrust for surfboard or motor boat.
