Technical Field

[0001] This utility model relates to the field of water pump impeller technology, specifically a composite water pump impeller. Background Technology

[0002] A water pump impeller converts mechanical energy into the kinetic energy and pressure energy of liquid flow, and achieves continuous fluid transport through centrifugal force.

[0003] Currently, when the impeller blades inside the water pump are rotating at high speed, the guided water flow will directly act on the impeller. Impurities such as sand and gravel mixed in the water flow will directly impact the impeller and its external blades. In severe cases, this will accelerate the wear of the impeller and its blades, directly affecting the service life of the impeller.

[0004] In view of this, a composite water pump impeller was designed to solve the above problems. Utility Model Content

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0017] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0018] The following describes, with reference to the accompanying drawings, some embodiments of a composite water pump impeller provided by this utility model. Example

[0019] Combination Figures 1 to 5 As shown, the present invention provides a composite water pump impeller, including an impeller assembly 100 and a blade protection mechanism 200 installed on the impeller assembly 100. The blade protection mechanism 200 is used to actively filter the water flow entering the water pump to improve the buffer protection of the impeller.

[0020] The impeller assembly 100 includes an impeller main shaft 110 and two clips 140, an impeller body 120 fixedly installed outside the impeller main shaft 110, a load-bearing beam 130 fixedly installed at the outer end of the impeller main shaft 110, two symmetrically distributed slots 1101 opened on both sides of the impeller main shaft 110 facing the end of the load-bearing beam 130, and the two clips 140 respectively snap into the two slots 1101 and the first bolt 1401 inserted into the clips 140 and fixed in the slots 1101; The blade protection mechanism 200 includes an impeller subshaft 210 movably installed outside the load-bearing beam 130, a sliding sleeve 220 movably installed outside the impeller subshaft 210, a screen bucket 240 fixedly installed outside the sliding sleeve 220, a limiting sleeve 260 bearing pressure between the impeller main shaft 110 and the impeller body 120, a sliding sleeve 2601 movably installed inside the limiting sleeve 260, a sliding column 2602 fixedly installed outside the load-bearing beam 130, a slider 2603 movably installed in the groove on the outer wall of the sliding column 2602, and a column head 2604 movably installed inside the slider 2603 and extending to the outside of the sliding sleeve 2601. One end of the limiting sleeve 260 is movably installed between two clips 140; The sieve hopper 240 has a funnel-shaped structure, and filter screen holes are provided on the inclined surface of the sieve hopper 240 away from the impeller body 120.

[0021] Preferably, the load-bearing beam 130 is welded to the impeller main shaft 110, and a rubber gasket is fixedly installed on the inner wall of the slot 1101. When the buckle 140 is engaged with the inner side of the slot 1101 and pressed against the rubber gasket, the buckle 140, which is fixed by the first bolt 1401, limits and clamps the limiting sleeve 260. The limiting sleeve 260, which is fixedly installed on the inner end of the impeller secondary shaft 210, can provide a sufficiently stable sliding carrier for the reciprocating extension of the sliding sleeve 2601 and the column head 2604. Finally, the traction plate 250, the fixing plate 230 and the sliding sleeve 220 pulled by the column head 2604 will vibrate at high frequency along the outside of the impeller secondary shaft 210. Example

[0022] Combination Figures 2 to 5 As shown, based on embodiment 1, the bottom of the sliding sleeve 220 is provided with a groove, and the second bolt 2201 is installed in the internal thread of the groove; The sliding sleeve 220 has an insertion hole at one end facing the limiting sleeve 260, and a fixing plate 230 is inserted into the insertion hole. The threaded section of the second bolt 2201 is adapted to penetrate into the interior of the fixing plate 230. A traction plate 250 is movably installed at the other end of the fixing plate 230. The other end of the traction plate 250 is movably mounted on the column head 2604; The outer walls at both ends of the limiting sleeve 260 are provided with annular grooves, and the ends of the two buckles 140 that are away from the impeller main shaft 110 are fitted into annular grooves. The top and bottom of the limiting sleeve 260 are provided with sliding grooves, and the end tube at the bottom of the sliding sleeve 2601 is adapted to pass through the sliding groove at the bottom of the limiting sleeve 260.

[0023] Preferably, the impeller subshaft 210 and the load-bearing beam 130 can be connected by bearings. When the impeller subshaft 210 is fixedly installed in the inner cavity of the water pump, the driven impeller main shaft 110, impeller body 120 and load-bearing beam 130 will rotate at high speed around the internal hole of the impeller subshaft 210. At this time, the sliding sleeve 220 and the screen bucket 240, which use the impeller subshaft 210 as the bearing platform, will actively filter the water flow entering the inner cavity of the water pump, thereby cleaning the sand and impurities in the water flow to avoid damage to the impeller body 120 caused by the impurities carried by the water pressure.

[0024] The working principle and usage process of this utility model are as follows: After the impeller structure is installed in the inner cavity of the water pump, the outer wall of the impeller body 120 fits and conforms to the inner wall of the water pump. Then, the impeller secondary shaft 210 is fixed in the inner cavity of the water pump to ensure that the impeller secondary shaft 210 is in a fixed state. As the impeller main shaft 110 is driven, the impeller body 120 installed outside the impeller main shaft 110 will rotate at high speed and guide the water. As the impeller body 120 continues to guide the water during rotation, the sliding column 2602 installed outside the load-bearing beam 130 will drive the slider 2603 and the column head 2604 to reciprocate. The traction plate 250 installed at the bottom of the column head 2604 will drive the fixed plate 230 to perform high-frequency extension and retraction. Finally, the fixed plate 230 will drive the sliding sleeve 220 and the screen bucket 240 to actively screen and vibrate the water flow towards the impeller body 120. During the high-frequency vibration of the screen bucket 240, the continuously guided water flow is filtered by the inclined surface and mesh of the screen bucket 240, and impurities such as sand and gravel can be blocked. At the same time, it can provide buffer protection for the blades of the impeller body 120, thereby effectively improving the service life of the impeller body 120.

[0025] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
