[0026] Please see Figures 1 to 6 This utility model discloses a pump impeller structure including a hub body 100, which is hollow and connected to an external motor shaft 700. The hub body 100 rotates together with the motor shaft 700. The hub body 100 includes a blade portion 110, which is a hollow spherical structure. The blade portion 110 is provided with mounting grooves 111 at intervals. The mounting grooves 111 are provided with mounting seats 200, and blades 300 are fixedly connected to the mounting seats 200. By placing the blades 300 on the mounting seats 200 and fixing them in the mounting grooves 111, the blades 300 are designed to be detachable. When one of the blades 300 is damaged, it can be removed from the mounting groove 111 for replacement without replacing the entire pump impeller structure, including the hub body 100 and the blades 300, thus effectively reducing resource waste and lowering the impeller's operating cost.

[0027] In one embodiment, the hub body 100 further includes a docking portion 120 and a rotating shaft portion 130. The docking portion 120 is disposed at one end of the blade portion 110, and the rotating shaft portion 130 is disposed at the other end of the blade portion 110. The docking portion 120 has an annular cross-section and is used to connect an external sealing head 600. The sealing head 600 is fixed to the docking portion 120 by bolts to seal the end of the hub body 100, preventing external water from entering the inner side of the hub body 100 through the docking portion 120, thereby facilitating... This utility model's impeller structure transports water; the rotating shaft 130 has a conical truncated structure and is hollow to facilitate fixed connection with an external motor shaft 700; furthermore, a mating groove 131 is provided on the inner side of the rotating shaft 130, and a mating protrusion is provided on the motor shaft 700, thereby ensuring a secure connection between the motor shaft 700 and the rotating shaft 130, so that the movement of the motor shaft 700 drives the rotating shaft 130 to rotate, thereby causing the hub body 100 to rotate as well.

[0028] Furthermore, to further enhance the sealing effect between the mating part 120 and the sealing head 600, a sealing ring (not shown) will be provided between the mating part 120 and the sealing head 600. The sealing effect of the sealing ring will be further enhanced. Specifically, a sealing groove for placing the sealing ring is provided on the inner side of the mating part 120. The sealing ring is placed in the sealing groove. When the sealing head 600 and the mating part 120 are mated, the sealing ring can block the gap between the sealing head 600 and the mating part 120, thereby improving the sealing effect between the mating part 120 and the sealing head 600.

[0029] In one embodiment, both the cross-section of the mounting groove 111 and the cross-section of the mounting base 200 are circular, which allows the mounting base 200 to be placed in the mounting groove 111 at any angle. Alternatively, the cross-sections of the mounting groove 111 and the mounting base 200 can also be designed as triangular, quadrilateral, or other polygonal structures, with the main effect of ensuring that the mounting base 200 can be stably placed in the mounting groove 111.

[0030] In one embodiment, a limiting groove 112 is provided in the mounting groove 111, and a limiting hole 210 is provided on the mounting base 200. The limiting hole 210 is provided through the mounting base 200, and can also be designed as a blind hole structure as needed. The mounting base 200 is locked in the mounting groove 111 by the limiting member 400, so that the mounting base 200 will not rotate in the mounting groove 111, thus avoiding the situation where the mounting base 200 rotates in its circumferential direction after being placed in the mounting groove 111. The number of limiting grooves 112 and limiting holes 210 can be designed to be multiple. In this embodiment, the limiting member 400 is a cylindrical pin structure, and the number of limiting grooves 112 and limiting holes 210 is 4.

[0031] In one embodiment, the diameter of the limiting hole 210 facing the mounting groove 111 is larger than the diameter of the hole away from the mounting groove 111, so that the limiting member 400 is placed in the space enclosed by the mounting groove 111 and the limiting hole 210, preventing the limiting member 400 from passing through the other end of the limiting hole 210 and affecting the placement effect of the mounting base 200 in the mounting groove 111.

[0032] Furthermore, to ensure that the mounting base 200 is securely fixed in the mounting groove 111, the mounting base 200 is provided with a mounting post 220 protruding from the side facing the mounting groove 111. The mounting groove 111 is provided with a mounting hole 113 that penetrates the bottom of the mounting groove 111. The mounting post 220 is provided through the mounting hole 113. The end of the mounting post 220 is provided with a threaded part. The end of the mounting post 220 is fastened to the inside of the hub body 100 by a nut 230. The nut 230 is fixed on the threaded part, so that the mounting post 220 can be securely fixed in the mounting hole 113, thereby ensuring that the mounting base 200 is securely fixed in the mounting groove 111.

[0033] Alternatively, the mounting base 200 is provided with a fixing hole, and the mounting base 200 is fixed in the mounting groove 111 by a fastener. The fastener passes through the fixing hole and is placed in the fixing groove, so that the mounting base 200 is stably fixed in the mounting groove 111. In this embodiment, the fastener is a bolt structure. By fixing with the fastener, the mounting base 200 can be stably fixed in the mounting groove 111 without the need for an additional mounting post 220 structure.

[0034] In one embodiment, an annular groove 240 is provided at the bottom end of the mounting base 200. The annular groove 240 is located around the mounting post 220. A sealing ring 500 is provided inside the annular groove 240. The sealing ring 500 protrudes from the annular groove 240, so that when the mounting base 200 is placed in the mounting groove 111, the sealing ring 500 is clamped by the bottom of the mounting base 200 and the mounting groove 111, effectively sealing the gap between the mounting base 200 and the mounting groove 111. This prevents external media from entering the hollow space inside the wheel hub body 100 through the gap between the mounting base 200 and the mounting groove 111, effectively ensuring the quality and service life of the wheel hub body 100.

[0035] In one embodiment, the mounting base 200 and the blade 300 are integrally formed, thereby improving the stability of the blade 300 mounted on the hub body 100 and facilitating better disassembly and replacement of the blade 300. In addition, by detaching and connecting the blade 300 to the hub body 100, the blade 300 can be cast separately, ensuring the forming effect of the blade 300 during the machining process, thereby ensuring the performance of the impeller structure.

[0036] Alternatively, the blade 300 can be separately disposed from the mounting base 200. The blade 300 and the mounting base 200 can be assembled together by a connecting structure. Commonly used structures by those skilled in the art can be used for assembly. For example, a positioning post can be provided on the blade 300 and a positioning hole can be provided on the mounting base 200. The positioning post can be placed in the positioning hole to complete the assembly connection between the blade 300 and the mounting base 200. Alternatively, a buckle can be provided on the blade 300 and a locking hole can be provided on the mounting base 200. The buckle can be placed in the locking hole to complete the assembly connection between the blade 300 and the mounting base 200, etc., which will not be elaborated here.

[0037] In one embodiment, the blade 300 may be constructed of materials such as austenitic stainless steel, titanium alloy, or nickel alloy. By designing the blade 300 as a detachable structure, the maintenance cost of the impeller structure can be effectively reduced.

[0038] In the specific assembly of this utility model, the blade portion 110 is designed as a hollow spherical structure, and a mounting groove 111 is provided on the blade portion 110. Then, the mounting seat 200 with blade 300 is placed in the mounting groove 111, so that the blade 300 is firmly fixed to the outer side of the hub body 100. When one of the blades 300 is damaged, the blade 300 can be removed from the mounting groove 111 for replacement, without having to replace the entire pump body impeller structure hub body 100 and blade 300 at the same time, effectively reducing resource waste and thus reducing the impeller usage cost.

[0039] In summary, the pump impeller structure of this utility model provides a hollow blade portion 110 on the hub body 100, and a mounting groove 111 on the blade portion 110 to fix the blade 300 to the mounting base 200. The mounting base 200 is fixed in the mounting groove 111, making the blade 300 a detachable structure. When one of the blades 300 is damaged, it can be removed from the mounting groove 111 for replacement without having to replace the entire pump impeller structure, including the hub body 100 and the blades 300, effectively reducing resource waste and thus lowering the impeller's operating cost.
