The present invention mainly relates to a small output submersible pump used for an aquarium installation, and in particular, the output capacity of the submersible pump can increase the drainage capacity of the submersible pump, adjust the position of the drain arbitrarily, and can easily attach the pump itself more easily. It is about.

In general, the water output submersible pump is small in size and usually has a structure in which pressure is applied by the rotation of the propeller to lift up the liquid (water).

Therefore, propellers of small power submersible pumps usually have 5-6 feathers and are manufactured in a small size, and the feathers are manufactured in the same size. It is well known that the larger the size of the feather, the larger the pump drainage capacity and the smaller the pumping capacity, but the smaller the output power pump is.

Therefore, these conventional submersible submersible pumps have a problem that they have a small drainage capacity compared to the pump output due to the size limitations, and the flexible connection of the drain hoses due to the fixed drainage of the pump. As a result, the installation was not performed smoothly, which caused the load to be increased on the profiler, resulting in a reduction in drainage capacity.

In addition, the conventional low power submersible pump has no attachment structure to other objects, so that the size of the propeller blade is large and small, and the position of the drain hole can be arbitrarily adjusted to reduce the load applied to the propeller while As it is possible to assemble the installation auxiliary plate having the suction port to increase the pump drainage capacity and to facilitate the easy installation, as described in more detail based on the accompanying drawings as follows.

1 is a separation of the submersible pump of the present invention, (10) is a pump body with a built-in stator (11), (20) is a propeller having a rotor (21) at the rear side and (30) an inlet (31) And the pressure chamber cap having a drain hole 32, 40 is an installation auxiliary plate body in which an adsorption hole 41 is attached to the corner portion.

Therefore, the propeller 20 is inserted into the rotor hole 12 of the pump body 10 and is arranged, and the pressure chamber cap 30 is formed on the front side of the pump body 10, "L" type finger piece 13 In the cap 13, the cap outer circumferences 33 and 33 'are inserted into and press-fitted to form a pressure chamber 50 in which the propeller 20 is rotated.

The feather of the propeller 20 has a long feather (20a) and a short feather (20b) is formed step by step, and a plurality of grooves (33a) in the cap outer circumference (33, 33 ') of the pressure chamber cap 30 In addition, on the inner surface of the finger pieces 13 and 13 ', the jar projection 13a, which is inserted into the finger trough groove 33a, protrudes, and is configured to be touched and shot.

In addition, the installation auxiliary plate 40 has a wedge-shaped binding piece 42, 42 'protruding from an upper surface thereof, and the binding stone piece 42 of the bottom surface 10a and both sides 10b, 10b' of the pump body 10. The wedge-shaped grooves 14, 14 'and 14 "into which 42' is to be inserted are provided respectively.

In the drawings, reference numeral 22a denotes a shaft support, 43 an auxiliary protrusion 51 is a drain hose, and 52 is a power line.

When the power is supplied to the stator 11, the present invention configured as described above rotates the rotor 21 and the propeller 20 by the armature action, and the pressure in the pressure chamber 50 is caused by the rotation of the propeller 20. As it is generated, the external liquid is introduced into the inlet 31 and discharged to the drain 32 is the same as before.

However, according to the present invention, since the propeller 20 having the long feather 20a and the short feather 20b is rotated and the pressure chamber cap 30 is rotated and adjusted, the position of the drain port 32 can be arbitrarily appropriately adjusted. Since the pressure can be doubled, the drainage capacity can be increased.

That is, the cap outer circumferences 33 and 33 ′ of the pressure chamber cap 30 have an external force because the tungsten protrusions 13a of the tungsten pieces 13 and 13 ′ are inserted into the tungsten groove 33a and are supported. If it is not rotated by the rotation, it will not flow. When rotating by applying an external force, the projections 13a are separated from the grooves 33a by the external force and are rotatable. When the rotation stops, the points of the projections 13a are stopped. The pressure chamber cap 30 is in a floating state again by being inserted into the other tungsten groove 33a which is reached by the copper tungsten protrusion 13a.

Therefore, the pressure chamber cap 30 can be arbitrarily rotated from the pump body 10 due to the above-described hardening and coalescing action of the protrusion 13a and the groove 33a. The angle position of the drain port 32 can be adjusted arbitrarily (refer FIG. 3).

Therefore, since the position of the drain hole 32 can be adjusted and used according to the connection position of the drain hose 51 connected to the drain hole 32, the drain hose 51 can be installed without being bent and thereby the drain hose ( Since it is possible to weaken the drainage flow resistance of 51) as much as possible, it is possible to reduce the drainage resistance in the pressure chamber 30, so that the rotational load of the propeller 20 can be reduced.

And the profile 20 takes less of the rotational load when some of the feathers have a single feather (20b) than the feathers all have a long feather (20a). That is, since the rotational resistance to the fluid is reduced by the length shorter than the long feather 20a, the rotational load of the propeller 20 is eventually reduced.

Therefore, due to the decrease in the drainage resistance and the decrease in the rotational load of the propeller 20 due to the decrease in the rotational resistance of the vane, the submersible pump having a small power can exert a greater output than the conventional one, thereby rotating the propeller 20. The speed RPM and the drainage capacity are increased.

In addition, the present invention facilitates the binding protrusions 42 and 42 'of the installation auxiliary plate 40 having the suction holes 4 in the insertion recesses 14, 14' and 14 "of the pump body 10. It can be inserted and detached to make it very easy to install.For example, when fixedly installed on the tank bottom plate 53, as shown in FIG. 2, the recess groove recessed in the bottom surface 10a of the pump body 10 is illustrated. After assembling the binding protrusions 42 and 42 'to the 14 and allowing the suction port 41 to be adsorbed to the tank bottom plate 53, the underwater pump is firmly attached and installed. By selectively binding the installation auxiliary plate body 40 on both sides of the pump body 10 as necessary to allow the suction port 41 to be adsorbed and installed, it is easy to fix the installation in the desired place.

As described above, the present invention can reduce the rotational load of the propeller by the rotational force of the drain hole 32 at the same time as the adoption of the propeller 20 having the long and short blades 20a, 20b. Since it has the effect of having a capacity (pump capacity) and the position of the drain hole 32 is adjustable, the installation with the suction hole 41 and the effect of facilitating easy connection and proper installation of the drain hose 51 can be achieved. As the selective binding of the auxiliary plate (40) has the effect that can be more easily, easily fixed, installation in an appropriate place it is possible to further improve the product reliability.
