An impeller 102 is installed in the inner cavity of the housing 101, and a guide structure is provided in the impeller 102, one side of which is fixed with a connecting shaft, which passes through the hole opened on the end face of the housing 101 and can be fixed to the motor shaft end. The medium entering from the water inlet flows to the guide structure, and is discharged to the water outlet through the rotation of the impeller 102.

[0030] Preferably, the upper end surface of the base 201 is fixedly connected to the supporting foot at the bottom of the shell 101, and a transmission assembly 203 is provided on the surface of the base 201. In this embodiment, the transmission assembly 203 is a screw pair, and the slide 202 is fixedly connected to the slider of the screw pair. When the screw rotates, it can push the slide 202 to move axially, and the extension direction of the screw is consistent with the axial direction of the impeller 102.

When separation is required, the connection needs to be disconnected and the screw rod can be driven in the reverse direction.

[0032] Example 2

[0033] Reference Figure 1 and Figure 4 , which is the second embodiment of the present invention, and is different from the first embodiment in that: the docking unit 200 is arranged at the bottom of the conveying unit 100, including a base 201, a slide 202 arranged on the surface of the base 201, a transmission component 203 arranged on one side of the slide 202, and a positioning sleeve 204 arranged on the side wall of the shell 101, wherein the transmission component 203 can adopt an electric push rod or a hydraulic push rod.

[0034] It should be noted that a push rod is fixed on the surface of the base 201, and the push rod driving mode is not limited. The push rod extension direction is consistent with the axis direction of the impeller 102, and the side wall of the slide 202 along the axis direction of the impeller 102 is fixedly connected to the push rod. The motor is fixed on the upper surface of the slide 202.

[0035] Consistent with Example 1, the motor shaft is aligned with the center of the end of the impeller 102, and then the push rod is driven to move so that the slide 202 is pushed toward the impeller 102. At this time, the motor and the impeller 102 are docked, and finally the two are fixed by means of keys, couplings, bolts, etc. At this time, the installation of the motor is completed. When separation is required, the connection needs to be disconnected and the push rod can be driven in the reverse direction.

[0036] Example 3

[0037] Reference Figure 1 to Figure 4 , which is a third embodiment of the present invention, comprises a conveying unit 100, comprising a housing 101, an impeller 102 disposed inside the housing 101, and a sealing sleeve 103 disposed on one side of the impeller 102;

[0038] The docking unit 200 is disposed at the bottom of the conveying unit 100 , and includes a base 201 , a slide 202 disposed on the surface of the base 201 , a transmission assembly 203 disposed on one side of the slide 202 , and a positioning sleeve 204 disposed on the side wall of the shell 101 .

[0039] Furthermore, the housing 101 includes a water inlet 101 a disposed on an end surface thereof, a water outlet 101 b disposed on a side wall of the housing 101 , and a sealing cylinder 101 c disposed on the other end surface of the housing 101 .

[0040] Furthermore, there is a connecting shaft 102a on one side of the impeller 102, and a connecting key 102b arranged on the inner wall of the connecting shaft 102a.

[0041] Furthermore, the base 201 includes a rack 201 a disposed on a surface thereof, and a limiting groove 201 b disposed on one side of the rack 201 a .

[0042] Furthermore, the slide 202 includes an orientation block 202a disposed on the bottom surface thereof, a limiting strip 202b disposed on the side wall of the orientation block 202a, and a positioning shaft 202c and a pair of shaft seats 202d disposed on one side of the orientation block 202a.

[0043] Further, the transmission assembly 203 includes a gear 203a and a screw rod 203b;

[0044] The spiral rod 203b includes a spiral strip 203b-1 disposed on the outer wall thereof, a limiting piece 203b-2 disposed at one end of the spiral rod 203b, and a connecting head 203b-3 disposed at the other end of the spiral rod 203b.

[0045] It should be noted that the shell 101 is in the shape of a volute with a cavity inside. A water outlet 101b is opened on the side wall of the shell 101, and through holes are opened in the centers of the two end faces, one of which is the water inlet 101a, and a sealing cylinder 101c is fixed around the opening of the other hole.

[0046] An impeller 102 is installed in the inner cavity of the housing 101. There is a guide structure in the impeller 102, and a connecting shaft is fixed to one end face. The connecting shaft 102a passes through the hole opened on the end face of the housing 101 and passes through the sealing cylinder 101c to the outside, so as to be connected with the motor shaft end. The medium entering from the water inlet 101a will flow to the guide structure. When the impeller 102 rotates, the medium is discharged along the guide structure to the side wall of the inner cavity of the housing 101 through the centrifugal action, and the water outlet 101b is connected with the inner cavity, so the medium is finally discharged from the water outlet 101b.

[0047] An annular sealing sleeve 103 is also sleeved between the opening of the sealing cylinder 101c and the side wall of the connecting shaft 102a. The connecting shaft 102a on the impeller 102 cooperates with the hole in the center of the end face of the casing 101 to form a first seal, and a second seal is formed between the sealing cylinder 101c, the sealing sleeve 103 and the outer part of the connecting shaft 102a to prevent medium leakage.

[0048] Preferably, a cavity that penetrates on one side is opened inside the connecting shaft 102a, and an axially extending connecting key 102b is fixed on the side wall of the cavity.

[0049] Preferably, there is a positioning sleeve 204 around the sealing cylinder 101c and fixedly connected to the end surface of the housing 101 for positioning and fixing one end of the motor shaft.

[0050] Preferably, a rack 201a is fixed on the upper surface of the base 201, and a limit groove 201b extending axially and passing through both ends is opened on the side wall of the rack 201a without teeth, and the groove shape of the limit groove 201b in the cross section is not limited. The base 201 is bolted to the support foot at the bottom of the housing 101.

[0051] Preferably, the surface of the slide 202 can be fixed to the support foot of the motor by bolts. An orientation block 202a is fixed at the bottom of the slide 202, and the orientation block 202a can fit the side of the rack 201a where the limit slot 201b is opened. Correspondingly, a limit strip 202b is fixed on the side wall of the orientation block 202a, and the shape of the cross section of the limit strip 202b is consistent with the limit slot 201b, and cooperates with the limit slot 201b, so that the slide 202 can move axially along the rack 201a.

[0052] At a position adjacent to the limiting strip 202b, a positioning shaft 202c and a pair of shaft seats 202d are fixed to the bottom of the slide 202, respectively. The positioning shaft 202c and the shaft seats 202d are both on the same side of the slide 202 and are adjacent to each other.

[0053] A gear 203a can be sleeved on the positioning shaft 202c, and the gear 203a is meshed with the rack 201a, and a spiral rod 203b is sleeved inside the shaft seat 202d, one end of the spiral rod 203b is fixed with a limiting plate 203b-2, and the other end is fixed with a connecting head 203b-3, which are respectively close to one side of the limiting plate 203b-2 to prevent the spiral rod 203b from detaching from the shaft seat 202d.

[0054] A spiral bar 203b-1 is fixed on the rod body of the spiral rod 203b and can be embedded in the teeth on the gear 203a. When the spiral bar 203b-1 rotates, it can drive the gear 203a to rotate, thereby controlling the movement of the slide 202 and the motor at its upper end.

[0055] It should be noted that the shaft end of the motor is generally provided with a keyway. When the motor and the impeller 102 are connected, it is necessary to ensure that the two are concentric. Then, when the motor shaft end is inserted into the connecting shaft 102a, the connecting key 102b is also inserted into the keyway. Then, when the motor rotates, the impeller 102 is dragged to rotate. Therefore, compared with the traditional disassembly and connection method, it is faster, and the gear 203a cannot reversely drive the screw rod 203b, and the slide 202 will not move. When disassembling, it is only necessary to control the screw rod 203b to rotate in the opposite direction. In addition, compared with the traditional connection method, it is also easier to achieve the docking of the motor and the impeller 102, as well as the hoisting of the motor itself.

[0056] In summary, the present invention can adopt a quick-disassembly and quick-assembly method to quickly replace or maintain the wearing parts of the water pump, such as the impeller and the motor, thereby ensuring the efficient operation of the circulating cooling system and ensuring normal power generation.

[0057] It is important to note that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
