It can also transport liquids, gas mixtures and liquids containing suspended solids.

[0003] In order to ensure the maintenance efficiency of the existing water pumps, the patent publication number CN205298070U discloses a split sewage pump body. When the matching sewage pump fails during operation or the impeller is entangled with dirt, the left pump body or the right pump body can be disassembled in time. Due to the split structure of the pump body, the built-in volute is completely exposed after opening, which is convenient for maintenance or cleaning operations. The two pump bodies are connected by multiple bolts and nuts. When disassembling, the operator needs to manually unscrew the bolts one by one, which is time-consuming and labor-intensive, and thus easily affects the efficiency of pump body disassembly.

DETAILED DESCRIPTION

[0042] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0043] like Figure 1 to Figure 4 As shown, this embodiment proposes a split water pump, including: a base plate 1, a pump shell 2, a delivery shell 3, a first connecting mechanism and a second connecting mechanism. Two pump shells 2 are provided, and the two pump shells 2 are sealed and contacted with each other and are rotatably arranged on the base plate 1. Two delivery shells 3 are provided, and the two delivery shells 3 are fixedly connected in the two pump shells 2 respectively. Through the cooperation among the base plate 1, the pump shell 2, the delivery shell 3, the first connecting mechanism and the second connecting mechanism, it is convenient to quickly disassemble and connect the pump shell 2, which is relatively time-saving and labor-saving, and improves the maintenance efficiency of the delivery pump.

[0044] Among them, the first connecting mechanism is arranged on the pump housing 2, which is used to lock the two pump housings 2. The first connecting mechanism includes: a fixed frame 4, a movable plate 5, an expansion plate 6, a driving rod 7, a driving plate 8, a driving screw 9, a first motor 10 and a moving assembly. Two sliding rods 19 are fixedly connected to the other pump housing 2, and two sliding holes are provided on the movable plate 5. The two sliding rods 19 are respectively slidably arranged in the two sliding holes. The fixed frame 4 is fixedly connected to one of the pump housings 2, and a locking hole is provided on the fixed frame 4. The movable plate 5 is slidably arranged on the other pump housing 2. The expansion plate 6 includes a driving rod 7, a driving plate 8, a driving screw 9, a first motor 10 and a moving assembly. There are multiple plates 6, and multiple expansion plates 6 are slidably arranged on the moving plate 5. There are multiple drive rods 7, and multiple drive rods 7 are respectively rotatably connected to the multiple expansion plates 6. The driving plate 8 is rotatably connected between the multiple drive rods 7. The driving screw 9 is rotatably arranged on the moving plate 5. The driving plate 8 is provided with a screw hole, and the driving screw 9 is threadedly connected in the screw hole. The first motor 10 is arranged on the moving plate 5, and the output end of the first motor 10 passes through the moving plate 5 and is fixedly connected to the driving screw 9. The moving assembly is arranged on another pump housing 2, and is used to drive the moving plate 5 to move. The moving assembly includes: a moving screw 11 and a second motor 12. The moving screw 11 is rotatably arranged on another pump housing 2. A screw hole is provided on the moving plate 5. The moving screw 11 is threadedly connected in the screw hole. The second motor 12 is arranged on another pump housing 2. The output end of the second motor 12 is fixedly connected to the moving screw 11. Specifically, when it is necessary to connect the two pump housings 2, the second motor 12 arranged on the pump housing 2 drives the moving screw 11 to rotate, and drives the moving plate 5 to move toward the fixing frame 4, so that the multiple expansion plates 6 are inserted into the lock. The first motor 10 arranged on the movable plate 5 drives the driving screw 9 to rotate, thereby driving the driving plate 8 to move. When the driving plate 8 moves, it drives the expansion plates 6 supported by the multiple driving rods 7 to expand, thereby fixing the multiple expansion plates 6 in the locking hole, and the second motor 12 drives the moving screw 11 to rotate in the opposite direction, so that the inclined surface arranged on the expansion plate 6 is against the fixing frame 4, thereby stably connecting the two pump casings 2. When the two pump casings 2 need to be disassembled, the reverse operation can be performed to quickly disassemble the two pump casings 2.

[0045] Among them, the second connecting mechanism is arranged on the conveying shell 3, which is used to lock the two conveying shells 3. The second connecting mechanism includes: a locking plate 13, a fixing plate 14, a clamping frame 15, a bidirectional screw 16 and a support assembly. The locking plate 13 is fixedly connected to one of the conveying shells 3, a slide groove is provided on the fixing plate 14, two clamping frames 15 are provided, and the two clamping frames 15 are both slidably arranged in the slide groove. The bidirectional screw 16 is rotatably arranged in the slide groove. Screw holes are provided on the two clamping frames 15, and the bidirectional screw 16 is threadedly connected between the two screw holes. There are two support assemblies, which are respectively arranged on the two clamping frames. The holder 15 is used to support the locking plate 13. The support assembly includes: a support screw 17 and a rotating block 18. A screw hole is opened on the clamping frame 15. The support screw 17 is threadedly connected in the screw hole. The rotating block 18 is fixedly connected to the support screw 17. Specifically, the operator rotates the bidirectional screw 16 to rotate, thereby driving the two clamping frames 15 to clamp the locking plate 13, and the operator drives the rotating block 18 and the support screw 17 to rotate, so that the support screw 17 is against the locking plate 13, thereby locking the two conveying shells 3, and vice versa when the conveying shell 3 needs to be disassembled.

[0046] In this embodiment, when the two pump casings 2 need to be disassembled, the driving screw 9 is driven to rotate by the first motor 10 arranged on the movable plate 5, thereby driving the driving plate 8 to move. When the driving plate 8 moves, it drives the multiple driving rods 7 to support the expansion plates 6 to be recovered, thereby reducing the diameter between the multiple expansion plates 6. The moving screw 11 is driven to rotate by the second motor 12 arranged on the pump casing 2, and the moving plate 5 is driven to move toward the second motor 12, thereby moving the multiple expansion plates 6 away from the locking holes, and the two pump casings 2 can be quickly disassembled.

[0047] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
