Description

Technical Field

[0001] The utility model belongs to the technical field of submersible pumps, and particularly relates to a submersible pump shaft structure and a submersible pump which are convenient for maintenance. Background Technique

[0002] A submersible pump is an important device for pumping water from deep wells. When in use, the whole unit works underwater, extracting groundwater to the ground surface, and is used for domestic water, mine rescue, industrial cooling, farmland irrigation, seawater lifting, ship ballasting, and can also be used for fountain landscapes.

[0003] When the submersible pump has not been used underwater for a long time, its shaft is prone to being locked and unable to start again. Currently, when encountering such a situation, the submersible pump needs to be taken out, and the shaft is axially displaced through tools so that the shaft can rotate again, and then the submersible pump is installed underwater. This process is relatively cumbersome and the cost is also high. Content of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies in the prior art, solve or at least alleviate the problems of cumbersome maintenance and high cost when the current submersible pump shaft is locked after being unused underwater for a long time, and provide a submersible pump shaft structure and a submersible pump which are convenient for maintenance.

[0005] The utility model is realized through the following technical solutions:

[0006] A submersible pump shaft structure convenient for maintenance is arranged on a section of the submersible pump shaft close to the water outlet end of the submersible pump. The submersible pump shaft structure includes a maintenance column. The longitudinal section of the maintenance column is T-shaped. The end of the vertical section of the maintenance column is fixedly connected to the end of the submersible pump shaft and is coaxially arranged with the submersible pump shaft. The submersible pump shaft is axially displaced by clamping the maintenance column with tools.

[0007] In order to further realize the utility model, the following technical solutions can be preferably selected:

[0008] Preferably, the lower part of the vertical section of the maintenance column is threadedly sleeved on the end of the submersible pump shaft.

[0009] Preferably, the submersible pump shaft structure further includes a valve plate. The valve plate is coaxially arranged with the submersible pump shaft and a sliding hole is axially arranged in the middle thereof. The sliding hole is hermetically and slidably sleeved on the submersible pump shaft;

[0010] A circular boss is horizontally arranged on the inner wall of the submersible pump housing. When the valve plate is at the lowest position, the periphery of the lower surface of the valve plate is hermetically attached to the boss. The outer diameter value of the valve plate is smaller than the inner diameter value of the submersible pump housing.

[0011] Preferably, the lower surface of the valve plate is an outwardly convex arc surface.

[0012] Preferably, the diameter value of the sliding hole is greater than the diameter value of the horizontal section of the maintenance column.

[0013] A submersible pump, the submersible pump includes a submersible pump shaft structure that is convenient for maintenance.

[0014] Through the above technical solution, the beneficial effect of the present utility model is:

[0015] The present utility model provides a maintenance column at the upper end of the submersible pump shaft. When the shaft is locked, a workpiece is extended underwater to clamp the maintenance column, thereby driving the axial movement of the submersible pump shaft. There is no need to remove the submersible pump or reinstall it, reducing the maintenance process and cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In the description of the present utility model, it should also be noted that, unless otherwise clearly defined and limited, the terms "set", "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Embodiment 1:

[0023] As Figures 1 - 3As shown in the figure, a submersible pump shaft structure facilitating maintenance is provided on a section of the submersible pump shaft close to the water outlet end of the submersible pump. It is characterized in that the submersible pump shaft structure includes a maintenance column 1. The longitudinal section of the maintenance column 1 is in a T shape. The end of the vertical section of the maintenance column 1 is fixedly connected to the end of the submersible pump shaft and is coaxially arranged with the submersible pump shaft. The submersible pump shaft can be axially displaced by clamping the maintenance column 1 with a tool.

[0024] In the present utility model, the maintenance column 1 is provided at the upper end of the submersible pump shaft. When the shaft is locked, a workpiece is inserted underwater to clamp the maintenance column 1, thereby driving the axial displacement of the submersible pump shaft. It is not necessary to take out the submersible pump or reinstall it again, reducing the maintenance process and cost.

[0025] For the convenience of processing, production and modification, the lower part of the vertical section of the maintenance column 1 is threadedly sleeved on the end of the submersible pump shaft.
