Description

Technical Field

[0001] This utility model relates to the field of axial flow pump technology, and in particular to a coupled axial flow pump station. Background Technology

[0002] Axial flow pumps are low-head, high-flow horizontal submersible pumps widely used in urban stormwater pumping stations, flood control pumping stations, and drainage pumping stations. Axial flow pumps typically use connectors to fix the pump body to the bottom of the pool or other structures, requiring maintenance personnel to descend to the bottom of the pool for disassembly during installation and maintenance, making them inconvenient to use.

[0003] There are also some self-coupling submersible cross-flow pumps in the existing technology, such as the Chinese utility model patent with application number CN201520482654.2 entitled "An Automatic Coupling Submersible Cross-flow Pump". By adding a guiding mechanism and using a guide rod for guidance, it can realize the automatic coupling and quick installation of the submersible cross-flow pump. However, the sealing between its pump outlet and the through-wall pipe is not strong, which will lead to leakage between the pump outlet and the through-wall pipe, affecting the drainage effect of the submersible cross-flow pump. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a coupled axial flow pump station, which uses its own gravity to achieve sealing of the outlet of the axial flow pump, with good sealing effect, and can realize the self-coupling installation of the axial flow pump, with a simple overall structure.

[0005] This utility model is achieved using the following technical solution: a coupled axial flow pump station, comprising: a pump base, a chute connecting frame, a chute, an axial flow pump assembly, a through-pipe structure, a flap gate structure, a limiting groove, and a connecting plate. Two chutes are vertically fixed to the front side of the pump base via two rows of chute connecting frames. The limiting groove is fixed to the bottom end of the chute. The outer end of the connecting plate is fixed to the rear side of the limiting groove, and the inner end of the connecting plate is fixedly connected to the front end of the through-pipe structure. The axial flow pump assembly is installed on the two limiting grooves, so that the rear end of the axial flow pump assembly is tightly fitted to the front end of the through-pipe structure. The through-pipe structure passes through the lower part of the pump base, with the front part of the through-pipe structure located at the front end of the pump base and the rear part of the through-pipe structure located at the rear end of the pump base. The flap gate structure is fixed to the rear end of the through-pipe structure.

[0006] Furthermore, the through pipe structure includes a pipe ring, a through pipe, and a rear flange. The through pipe passes through the lower part of the pump base, the pipe ring is fixed to the front end of the through pipe, and the rear flange is fixed to the rear end of the through pipe.

[0007] Furthermore, the axial flow pump assembly includes an axial flow pump, a slide block seat, a slide rod, and a connector. Two slide blocks are symmetrically fixed on the outer wall of the axial flow pump, and the two slide rods are respectively fixed on the outer side of the two slide blocks. A connector is also fixed on the upper outer wall of the axial flow pump for lifting the axial flow pump. A support frame is symmetrically fixed at the bottom end of the axial flow pump.

[0008] Furthermore, the connecting component is a threaded post, and there are two threaded posts, which are symmetrically fixed on the upper outer wall of the cross-flow pump.

[0009] Furthermore, the flap gate structure includes a flap gate body, hinges, a flap gate cover, and a flap gate flange. The flap gate flange is fixed to the front end of the flap gate body, and the rear end of the flap gate body is connected to the upper part of the flap gate cover by a number of hinges.

[0010] Furthermore, the limiting groove is trapezoidal, with the width of its upper opening being the same as the width of the inner wall of the slide groove, and the width of the lower opening of the limiting groove being smaller than the width of its upper opening.

[0011] Furthermore, the limiting groove, connecting plate, and tube ring are integrally formed.

[0012] Furthermore, the pump base is inverted T-shaped.

[0014] 1. This utility model discloses a coupled axial flow pump station, which enables the self-coupling installation of the axial flow pump, facilitating the installation and maintenance of the axial flow pump. Its overall structure is simple and its manufacturing cost is low.

[0015] 2. The present invention relates to a coupled axial flow pump station, which, through the structural design of a limiting groove, a connecting plate, and a pipe ring, allows the axial flow pump to have a backward horizontal displacement when it descends in the limiting groove using its outer sliding rod.

Detailed Implementation

[0023] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0024] The purpose of this invention is to address the shortcomings of existing technologies by providing a coupled axial flow pump station.

[0025] Example 1

[0026] This embodiment provides a coupled axial flow pump station, referring to... Figures 1-2 As shown, the system includes: a pump base 1, a chute connecting frame 2, a chute 3, a cross-flow pump assembly 4, a through-pipe structure 5, a flap gate structure 6, a limiting groove 7, and a connecting plate 8. The pump base 1 is inverted T-shaped. Two chute 3s are vertically fixed to the front side of the pump base 1 via two rows of chute connecting frames 2. The limiting groove 7 is fixed to the bottom end of the chute 3. The outer end of the connecting plate 8 is fixed to the rear side of the limiting groove 7, and the inner end of the connecting plate 8 is fixedly connected to the front end of the through-pipe structure 5. The cross-flow pump assembly 4 is installed on the two limiting grooves 7, so that the rear end of the cross-flow pump assembly 4 is tightly fitted with the front end of the through-pipe structure 5. The through-pipe structure 5 passes through the lower part of the pump base 1. The front part of the through-pipe structure 5 is located at the front end of the pump base 1, and the rear part of the through-pipe structure 5 is located at the rear end of the pump base 1. The flap gate structure 6 is fixed to the rear end of the through-pipe structure 5.

[0027] Specifically, refer to Figure 3As shown, the limiting groove 7 in this embodiment is trapezoidal, with its upper opening width being the same as the inner wall width of the slide groove 3, allowing the slide rod 43 to slide down the slide groove 3 and smoothly transition into the limiting groove 7. The lower opening width of the limiting groove 7 is smaller than the upper opening width. In this embodiment, the rear inner wall of the limiting groove 7 is further designed to be horizontal with the inner wall of the slide groove 3, while the front inner wall of the limiting groove 7 is inclined. This allows the slide rod 43 to have a rearward horizontal displacement when it descends vertically along the limiting groove 7, thereby enabling the rear end of the axial flow pump 41 to fit tightly with the pipe ring 51, achieving a seal at the outlet of the axial flow pump 41 under its own gravity. Preferably, in this embodiment, the limiting groove 7, the connecting plate 8, and the pipe ring 51 are integrally formed, which can improve the manufacturing precision of the limiting groove 7, the connecting plate 8, and the pipe ring 51, ensuring a tight seal between the rear end of the axial flow pump 41 and the pipe ring 51.

[0028] Reference Figures 3-4 As shown, the through pipe structure 5 includes a pipe ring 51, a through pipe 52 and a rear flange 53. The through pipe 52 passes through the lower part of the pump base 1, the pipe ring 51 is fixed to the front end of the through pipe 52, and the rear flange 53 is fixed to the rear end of the through pipe 52.

[0029] Reference Figure 5 As shown, the axial flow pump assembly 4 includes an axial flow pump 41, a slide bar seat 42, a slide bar 43, and a connector. Two slide bar seats 42 are symmetrically fixed on the outer wall of the axial flow pump 41, and two slide bars 43 are respectively fixed on the outer sides of the two slide bar seats 42. A connector is also fixed on the upper outer wall of the axial flow pump 41 for lifting the axial flow pump 41. A support frame 45 is symmetrically fixed at the bottom end of the axial flow pump 41. Specifically, in this embodiment, the connector is a threaded post 44, of which there are two, symmetrically fixed on the upper outer wall of the axial flow pump 41. It is connected to connectors in the prior art such as threaded lifting rings, and together with a steel wire rope or other pulling rope, it is used to pull and lower the axial flow pump 41.

[0030] Reference Figure 6 As shown, the flap gate structure 6 includes a flap gate body 61, hinges 62, a flap gate cover 63, and a flap gate flange 64. The flap gate flange 64 is fixed to the front end of the flap gate body 61. The rear end of the flap gate body 61 is connected to the upper part of the flap gate cover 63 through several hinges 62, so that the flap gate cover 63 can close when the external pressure of the flap gate body 61 is greater than its internal pressure.

[0031] This utility model discloses a coupled axial flow pump station. In use, a threaded lifting ring (not shown in the figure) is connected to a threaded column 44 via a threaded engagement, and a steel wire rope is attached to the threaded lifting ring. The axial flow pump assembly 4 is lifted, causing the two sliding rods 43 on the outside of the axial flow pump 41 to slide down along two sliding grooves 3. Upon reaching the bottom of the sliding groove 3, they transition into a limiting groove 7. As the sliding rods 43 continue to descend within the limiting groove 7, they experience a backward horizontal displacement, allowing the rear end of the axial flow pump 41 to tightly fit against the pipe ring 51. Under its own weight, the outlet of the axial flow pump 41 is sealed. The integrated design of the limiting groove 7, connecting plate 8, and pipe ring 51 improves manufacturing precision and ensures a better seal between the rear end of the axial flow pump 41 and the pipe ring 51, thus achieving self-coupling installation of the axial flow pump. This facilitates installation and maintenance of the axial flow pump, and its overall structure is simple with low manufacturing cost.

[0032] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
