Description

Technical Field

[0001] The present application relates to the technical field of submersible pumps, and in particular to a submersible pump structure. Background Art

[0002] A submersible pump is an underwater pump, also known as a submersible electric pump. They are usually placed in water to discharge water from deep water, such as extracting water from a pond, and then performing subsequent work in the pond. However, the bottom of the pond is complex, and the submersible pump is long and includes a pump body, an impeller, a motor, and a water inlet. The motor is installed inside one end of the pump body, the impeller is located in the pump body and rotates under the drive of the motor, and the water inlet is opened on the side of the pump body. When the submersible pump extracts water from the pond, the water inlet of the submersible pump cannot extract water in and out of the low-lying area, thereby affecting the work efficiency of subsequent staff. Utility Model Content

[0003] The utility model aims to provide a submersible pump structure in view of the defects and shortcomings of the prior art.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] It comprises a pump body, a rotating ring is arranged on the peripheral adapter sleeve of the pump body, an extension tube is arranged on the side wall of the rotating ring, one end of the extension tube is connected with the pump body, and a mesh is arranged on the peripheral side of the extension tube away from one end of the rotating ring.

[0006] Preferably, a plurality of through holes are evenly opened on the circumference of the pump body, and the plurality of through holes are located inside the rotating ring.

[0007] Preferably, the inner circumferences of both ends of the rotating ring are respectively provided with limiting rings, and the circumferential side of the pump body is provided with an annular groove for the limiting ring to be embedded in.

[0008] Preferably, a plurality of support frames are evenly arranged circumferentially at one end of the extension tube away from the rotating ring.

[0009] Preferably, the rotating ring includes a first ring sleeve and a second ring sleeve, one end of the extension tube is arranged on the outer side wall of the first ring sleeve, and two sides of the second ring sleeve are respectively assembled and fixed to two sides of the first ring sleeve.

[0010] Preferably, sealing rings are respectively provided between the inner sides of both ends of the rotating ring and the pump body.

[0011] Preferably, a filter ring is provided on the peripheral side of the extension tube away from one end of the rotating ring.

[0012] In summary, the present application includes at least one of the following beneficial technical effects:

[0013] 1. When it is necessary to extract water from the pond, when the submersible pump encounters a low-lying terrain, the extension pipe rotates under the rotation of the rotating ring, so that the other end of the extension pipe is close to the bottom of the low-lying pond until the extension pipe reaches the bottom of the low-lying pond. Then the motor is started to drive the impeller to rotate, and then the water in the pond enters from the mesh, then enters the pump body, and finally flows out from the outlet of the pump body, so that the submersible pump can pump out the water in the pond, thereby facilitating the subsequent work of the staff and improving the working efficiency of the submersible pump;

[0014] 2. When one end of the extension pipe is close to the bottom of the low-lying pond, the support frame prevents the end of the extension pipe from contacting the bottom of the pond, so that large debris at the bottom of the pond will not enter the mesh, thereby not affecting the transportation efficiency of the submersible pump;

[0015] 3. When installing the rotating ring, first put the first ring sleeve on the peripheral side of the pump body, and then assemble the second ring sleeve with the first ring tube, so that the first ring tube and the second ring tube are combined into a rotating ring, so that the rotating ring is installed and fixed on the peripheral side of the pump body.

[0020] The utility model is further described below in conjunction with the accompanying drawings.

[0021] The embodiment of the present application discloses a submersible pump structure.

[0022] Reference Figure 1, including a pump body 1, which is in a cylindrical tube shape, with a plurality of through holes 2 circumferentially opened on the circumference of the pump body 1, a rotating ring 3 sleeved on the circumference of the pump body 1, the rotating ring 3 covers the outer circumference of the plurality of through holes 2, an extension pipe 4 is welded and fixed to the outer wall of the rotating ring 3, a mesh 5 is opened on the circumference of the extension pipe 4 away from one end of the rotating ring 3, and a connecting ring 13 is opened on the circumference of the outer circumference of the mesh 5. The extension pipe 4 rotates under the rotation of the rotating ring 3, so that the other end of the extension pipe 4 approaches the low-lying bottom of the pond until the extension pipe 4 reaches the low-lying bottom, and then the motor is started to drive the impeller to rotate, and then the water in the pond enters from the mesh 5, then enters the pump body 1, and finally flows out from the outlet of the pump body 1.

[0023] Reference Figure 2 and Figure 3 The inner circumference of both ends of the rotating ring 3 is fixed with a limit ring 6, and the circumference of the pump body 1 is provided with two annular grooves 7 for the limit ring 6 to be embedded. The pump body 1 is provided with two installation grooves in the circumference of the side wall between the two annular grooves 7, and the installation groove is fixed with a sealing ring 8, and the outer circumference of the sealing ring 8 abuts against the inner side wall of the rotating ring 3. With the cooperation between the limit ring 6 and the annular groove 7, the rotating ring 3 can rotate on the circumference of the pump body 1 without axial movement.

[0024] The rotating ring 3 includes a first ring sleeve 9 and a second ring sleeve 10. One end of the extension tube 4 is welded and fixed to the outer wall of the first ring tube, and both sides of the second ring tube are fixed to both sides of the first ring tube by bolts. When installing the rotating ring 3, the first ring sleeve 9 is first sleeved on the circumference of the pump body 1, and then the second ring sleeve 10 is assembled with the first ring tube, so that the first ring tube and the second ring tube are combined into the rotating ring 3, so that the rotating ring 3 is installed and fixed on the circumference of the pump body 1.
