The specific embodiment
As shown in Figure 1, the cleaning machine for water tank 2 of first embodiment of the invention comprises a shell 4, first and second motor 6,8, first and second blade 10,12 and filter bag 14.This shell 4 is respectively equipped with first and second delivery port 40,42 in its relative both sides, and is provided with a water inlet 44 in its bottom.The opening of this filter bag 14 communicates with water inlet 44, and is installed in the shell 4, thereby foreign material or foul are stayed in the filter bag 14 in can be with water when cleaning machine for water tank is worked.This first and second blade 10,12 is located in the shell 4 and close respectively first and second delivery port 40,42, can be thereby this first and second blade 10,12 can be driven by first and second motor 6,8 respectively respectively to first and second delivery port 40,42 drainings, borrow the thrust that produces to first and second delivery port 40,42 drainings respectively can drive cleaning machine for water tank 2, it can be moved in the pond.For example, make cleaning machine for water tank 2 to direction.A moves, and just activates first motor 6 and makes it drive first blade 10 to 40 drainings of first delivery port, on the contrary, cleaning machine for water tank 2 is moved to the opposite direction of direction A, just activates second motor 8 and makes it drive second blade 12 to 42 drainings of second delivery port.
For increasing filter capacity, guarantee that water passes through filter bags 14 backs from water inlet 44 and discharges from first or second delivery port 40,42, shell 4 is provided with first and second door 46,48 respectively at first and second delivery port 40,42 places, when thereby first motor 6 drives 10 rotations of first blade to 40 drainings of first delivery port, open for first 46, and second 48 is closed.In like manner, thereby when second motor 8 drives 12 rotations of second blade to 42 drainings of second delivery port, open for second 48, and first 46 closed.Can prevent that like this sealing goes out from first delivery port 40 and then from second delivery port 42, perhaps goes out from second delivery port 42 and then from first delivery port 40.
This first and second 46,48 can be the door of controllable switch, also can be the door that freely swings.For the door of controllable switch, when first motor 6 is activated, just open the door 46 of first controllable switch, and close second controllable switch the door 48, otherwise, when second motor 8 is activated, just open the door 48 of second controllable switch, and close the door 46 of first controllable switch.And for the door that freely swings, when thereby first motor 6 drives 10 rotations of first blade to 40 drainings of first delivery port, hydraulic pressure is penetrated out first door 46 that freely swings, and the parital vacuum that 10 rotations of first blade cause is closed second door 48 that freely swings, otherwise, when thereby second motor 8 drove 12 rotations of second blade to 42 drainings of second delivery port, hydraulic pressure was penetrated out second door 48 that freely swings, and the parital vacuum that 12 rotations of second blade cause is closed first door 46 that freely swings.
First motor 6 in the described cleaning machine for water tank 2 and first blade 10 and second motor 8 and second blade 12 can be formed a water pump respectively, as turbine pump, centrifugal pump etc.
As shown in Figure 2, described cleaning machine for water tank 2 also can be established the 3rd delivery port 50 at the top of its shell 4, and correspondingly be provided with the 3rd blade 52 and the 3rd motor 54 near the 3rd delivery port 50 places, driving 52 rotations of the 3rd blade by the 3rd motor 54 can be to 50 draining of the 3rd delivery port.Thereby improve the operating efficiency of cleaning machine for water tank 2.In addition, the water inlet of shell 4 bottoms also can be offered a plurality of.
Fig. 3-4B is depicted as the cleaning machine for water tank 2 ' of second embodiment of the invention, and the difference of itself and first embodiment shown in Figure 1 is that it only uses a motor 7 to drive first and second blade 10,12 respectively.As shown in Figure 3, this motor 7 is a pair of steering motor, and it links to each other respectively with first, second blade 10,12 by first, second unilateral bearing 72,74, realizes that it drives the function of first, second blade 10,12 respectively.Utilize unilateral bearing only can pass on power at the Shi Caihui that turns to of appointment, the principle that then can skid at other direction, if first blade 10 of cleaning machine for water tank 2 ' rotates, just activate motor 7 and rotate towards a direction, such as just changeing, and make first unilateral bearing 72 pass on power direction for identical with this rotation direction, and the power direction that passes on of second unilateral bearing 74 is and this direction of rotation, like this, just can drive 10 rotations of first blade, and second blade 12 does not change.In like manner, second blade 12 of cleaning machine for water tank 2 ' to rotate, just activate motor 7 and rotate towards other direction, promptly rightabout like this, just can drive 12 rotations of second blade, and first blade 10 does not change.
Shown in Fig. 4 A-4B, this motor 7 is a pair of steering motor, one power wheel 70 is housed on it, first, second blade 10,12 links to each other with first and second gear 100,120 respectively, this first, second gear 100,120 meshes with first, second drive 76,78 respectively, and this first, second drive 76,78 can mesh with power wheel 70 respectively, thereby can realize that motor 7 drives the function of first, second blade 10,12 respectively.If first blade 10 of cleaning machine for water tank 2 ' rotates, just activating motor 7 rotates towards a direction, such as just changeing, and first drive 76 is meshed to drive the rotation of first blade 10 with power wheel 70, this moment second, drive 78 was thrown off with power wheel 70, like this, just can drive 10 rotations of first blade, and second blade 12 does not change.In like manner, want second blade 12 of cleaning machine for water tank 2 ' to rotate, just activating motor 7 rotates towards other direction, it is rightabout, and second drive 78 is meshed with power wheel 70 to drive the rotation of second blade 12, this moment first, drive 76 was thrown off with power wheel 70, like this, just can drive 12 rotations of second blade, and first blade 10 does not change.
Figure 5 shows that the cleaning machine for water tank 2 of third embodiment of the invention "; different with first and second embodiment is, and it only is located at the blade 11 that links to each other with this motor 7 in the shell with a motor 7 and and realizes respectively to first, second delivery port 40,42 drainings; thereby borrow the thrust that produces to first and second delivery port 40,42 drainings respectively to drive cleaning machine for water tank 2 ", it can be moved in the pond.This cleaning machine for water tank 2 " comprise that also one can control the door 47 to 40,42 drainings of first or second delivery port, thereby can control cleaning machine for water tank 2 " mobile direction.Described door 47 roughly is located at the centre of first and second delivery port 40,42, and can be around a rotating shaft 49 swings, and described blade 11 is roughly over against this rotating shaft 49, whereby if when 40 drainings of first delivery port, this 47 is flapped toward a side at second delivery port, 42 places and blocks the passage that leads to second delivery port 42, thereby realize toward the 40 outside drainings of first delivery port, if when 42 drainings of second delivery port, this 47 is flapped toward a side at first delivery port, 40 places and blocks the passage that leads to first delivery port 40, thereby realizes toward the 42 outside drainings of second delivery port.
Described motor 7 can be formed water pump with described blade 11, can be turbine pump, also can be centrifugal pump (as shown in Figure 6).
In sum, the present invention adopts fluid pressure type to drive cleaning machine for water tank 2,2 ', 2 ", it can be moved in the pond easily.
Should be understood that; for the person of ordinary skill of the art; can make various possible being equal to and change or replacement, and all these changes or replacement all should belong to the protection domain of claim of the present invention according to technical scheme of the present invention and technical conceive thereof.
