It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1 to 6 together, the structure of the submersible pump according to the present invention will now be described. Immersible pump structure is including the pump body 1, a plurality of reference column 2, rotating sleeve 4, a plurality of needle 8, fixed strip 10 and pivot 16 of keeping off. A plurality of reference column 2 sets up along the circumference of the pump body 1 water sucking mouth, and the cover is equipped with a plurality of gyro wheels 3 on the reference column 2. The rotating sleeve 4 is rotatably arranged on the outer side of the rollers 3, and a plurality of liquid inlet holes 5 communicated with the water suction ports are formed in the rotating sleeve 4. A plurality of blocking needles 8 are fixed on the outer wall of the rotating sleeve 4 at intervals. The fixed strip 10 is installed on the pump body 1, and a plurality of shearing rods 13 used for being in inserting fit with the blocking needles 8 are fixed on the fixed strip 10. The rotating shaft 16 penetrates through the inner side of the fixing strip 10, and the rotating shaft 16 is in transmission connection with the rotating sleeve 4. The blocking needle 8 is matched with the shearing rod 13 to shear impurities by means of rotation of the rotating sleeve 4.

The submersible pump structure provided by the invention has the beneficial effects that: compared with the prior art, the submersible pump structure is provided with a plurality of positioning columns 2 along the circumferential direction of the water suction port of the pump body 1. The rotating sleeve 4 is rotatably mounted on the outer side of the plurality of rollers 3. The rotating sleeve 4 is provided with a plurality of liquid inlet holes 5 communicated with the water suction port. A plurality of blocking needles 8 are fixed on the outer wall of the rotating sleeve 4, a fixing strip 10 is installed on the pump body 1, and a plurality of shearing rods 13 which are used for being in splicing fit with the blocking needles 8 are fixed on the fixing strip 10. The inner side of the fixed strip 10 is provided with a rotating shaft 16 in a penetrating way, and the rotating shaft 16 is connected with the rotating sleeve 4 in a transmission way.

In practical use, due to the limiting effect of the plurality of rollers 3, the rotating sleeve 4 rotates relative to the rollers 3 under the effect of the rotating shaft 16. The rotating sleeve 4 drives the blocking needle 8 to rotate, so that the blocking needle 8 and the shearing rod 13 are matched to shear impurities. In this application, cut impurity through the cooperation of keeping off needle 8 and shear bar 13, can prevent that impurity from piling up in water pump water absorption mouth department, cause the suction pump to block up, can use in the comparatively complicated occasion of impurity to the operation is stable.

Because the rotating sleeve 4 on the positioning column 2 is provided with the roller 3, the rotating sleeve 4 is positioned at the outer side of the water suction port through the plurality of rollers 3, and because the roller 3 rotates in the rotating process of the rotating sleeve 4, the resistance of the rotating sleeve 4 in the rotating process is reduced, and the required input power in the rotating process of the rotating shaft 16 is further reduced.

As a specific embodiment of the submersible pump structure provided by the present invention, please refer to fig. 1, fig. 2 and fig. 3, two side edges of the rotating sleeve 4 are fixed with gear rings 6; the rotating shaft 16 is provided with a gear 9 which is in transmission fit with the gear ring 6. In the present application, the rotating sleeve 4 needs to be driven to move by the rotating shaft 16, and the gear 9 needs to be engaged because a large force is needed to shear the impurities.

In order to enable the rotating sleeve 4 to rotate stably, gear rings 6 are arranged on the upper side and the lower side of the rotating sleeve 4, the gear rings 6 can be welded on the rotating sleeve 4, and the gear rings 6 can be directly adhered to the rotating sleeve 4 in the case of the environment which is not harsh. A gear 9 in driving fit with the gear ring 6 is arranged on the rotating shaft 16.

It should be pointed out that because the immersible pump needs soak in aqueous in the longer time, rotate cover 4 in addition, keep off needle 8, fixed strip 10 and pivot 16 etc. and all directly contact with water to have the transmission relation, in order to avoid because reasons such as rust, cause the cooperation inseparable, produce the interference even, for this application, reference column 2, gyro wheel 3, rotate cover 4, keep off needle 8, fixed strip 10, pivot 16, ring gear 6 and gear 9 are stainless steel. Even if the outside of the water sucking mouth of the pump body 1 is provided with the rotating sleeve 4, but because the rotating sleeve 4 is provided with the plurality of liquid inlet holes 5, the water sucking mouth of the pump body 1 can still suck liquid even if the rotating sleeve 4 rotates, and therefore normal use is not influenced.

As a specific embodiment of the submersible pump structure provided by the present invention, please refer to fig. 1 and 4, two ends of the fixing strip 10 are provided with connecting seats 12 for being mounted on the pump body 1, the connecting seats 12 are disposed above the gear ring 6, and are disposed to avoid the gear 9. In this application, the fixed strip 10 can be dismantled and connect on the pump body 1, also is provided with connecting seat 12 at the both ends of fixed strip 10 promptly, and connecting seat 12 accessible bolt mounting is fixed on the pump body 1. Because need install two gears 9 of being connected with the transmission of ring gear 6 on the pivot 16, pivot 16 need stabilize in fixed strip 10 internal rotation, in order to avoid fixing gear 9 behind the tip of pivot 16, because the diameter of pivot 16 is less, cause pivot 16 to receive the effort of ring gear 6 and take place crooked problem, in order to make pivot 16 have sufficient intensity, the both ends of pivot 16 are all rotated and are connected on two connecting seats 12, two gears 9 are located between two connecting seats 12, the cover is equipped with a plurality of bearings 15 between two gears 9, it is spacing through the cooperation of a plurality of bearings 15 and a plurality of connecting seats 12, can guarantee the stability of pivot 16, avoid because stress concentration, and lead to taking place crooked problem. A motor 11 is installed on one side of one of the connecting seats 12, and the motor 11 is installed on the pump body 1 and is arranged coaxially with the rotating shaft 16 for driving the rotating shaft 16 to rotate.

In order to avoid interference between the gear ring 6 and the gear 9 and the connecting seat 12, a through hole for avoiding the gear 9 is formed in the middle of the connecting seat 12 in a penetrating manner, and an avoiding groove for avoiding the gear ring 6 is formed in the bottom of the connecting seat 12.

As a specific embodiment of the submersible pump structure provided by the present invention, please refer to fig. 2 and 4, a communicating chamber is formed in the fixing strip 10, a plurality of flushing ports communicated with the communicating chamber are formed on the fixing strip 10, and the communicating chamber conveys liquid to the plurality of flushing ports through the liquid inlet pipe 14.
