Description

Technical Field

[0001] This utility model relates to the field of deep well pump technology, specifically a deep well pump with a convenient turbine structure that is easy to replace. Background Technology

[0002] Deep well pumps, at their core, consist of a segmented cylindrical pump casing and a long drive shaft running through it. Thanks to their advantages—a motor located on the surface, adaptability to extreme depths, and high head—they continue to play a vital role in deep well water extraction, especially in scenarios requiring extremely high reliability and easy surface maintenance, despite the high precision requirements of installation and the resulting loss of transmission efficiency. They are a classic alternative to submersible pumps in specific applications (particularly ultra-deep wells).

[0003] However, when maintaining and replacing the turbines of deep well pumps, the integrated design makes the replacement process very troublesome. Moreover, the maximum number of turbines is fixed, and it is impossible to add more turbines. For some areas with poor water quality, it is necessary to increase the drive power, which leads to increased energy consumption and limited applicability. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4 This utility model provides an embodiment of a deep well pump with a convenient turbine structure for replacement, comprising a drive module 10, a drive shaft 8 fixedly mounted at the end of the drive module 10, a housing 1 fixedly mounted on the outer wall of the drive module 10, a sealing disc 11 fixedly mounted inside the housing 1, a plurality of disassembly plates 3 threadedly mounted in the middle of the housing 1, a water outlet 12 mounted at one end of the housing 1, a plurality of water inlets 2 mounted in the middle of the housing 1, a plurality of first turbines 5 and second turbines 6 rotatably mounted in the middle of the plurality of disassembly plates 3, a sealing mechanism 9 mounted on the side wall of the plurality of first turbines 5, a snap-fit ​​mechanism 7 mounted at the center of the plurality of first turbines 5, and an installation mechanism 4 mounted on the inner side wall of the plurality of disassembly plates 3. When maintenance or turbine replacement is required, simply rotate the corresponding disassembly plate 3 to unlock its mounting mechanism 4, then remove the first turbine 5 and the second turbine 6 completely, and then rotate the corresponding disassembly plate 3 in the opposite direction. When the disassembly plate 3 rotates in the opposite direction, the mounting mechanism 4 drives the snap-fit ​​mechanism 7 to move axially, so that the snap-fit ​​mechanism 7 re-engages and drives synchronously with the drive shaft 8. The axial mechanism of the snap-fit ​​mechanism 7 drives the sealing mechanism 9 to squeeze and seal, and the reinstallation is complete.

[0022] Specifically, each of the aforementioned locking mechanisms 7 includes a locking shaft 71, a triangular groove 72, and a triangular block 73. The locking shaft 71 is fixedly disposed at the center of the first turbine 5 and the second turbine 6. The triangular groove 72 is disposed at the top of the locking shaft 71, and the triangular block 73 is fixedly disposed at the bottom of the locking shaft 71. By moving the triangular block 73 into the corresponding triangular groove 72 for locking and limiting, the drive shaft 8 drives the locked shaft 71, which is then driven by the drive module 10 to rotate. The drive shaft 8 drives the triangular block 73 and the locking shaft 71 to rotate synchronously. This allows for the arbitrary disassembly of the first turbine 5 and the second turbine 6 during maintenance, and during installation, only rotation is needed to achieve automatic docking and synchronous transmission. The number of turbines can be increased or decreased as needed to reduce or increase suction. It has a wide range of applications, is simple to operate, and is convenient and quick.

[0023] Specifically, each of the triangular grooves 72 has a bevel 721 on its sidewall, and the triangular groove 72 engages with the triangular block 73; the bevel 721 increases the accuracy of the docking and avoids misalignment and docking failure.

[0024] Specifically, each of the aforementioned installation mechanisms 4 includes an external thread 41 and an internal thread 42. The external thread 41 is located at the bottom of the inner wall of the corresponding disassembly plate 3, and the internal thread 42 is located at the top of the inner wall of the corresponding disassembly plate 3. The external thread 41 and the internal thread 42 are mutually compatible. By rotating the disassembly plate 3, the external thread 41 on the disassembly plate 3 is screwed into the corresponding internal thread 42. This achieves rapid and stable installation. Furthermore, based on the characteristic that the threads will move axially a certain distance during rotation and connection, the locking shaft 71 and the triangular block 73 are used for locking and transmission, reducing operation steps, simplifying operation, making it convenient and quick, and resulting in low overall cost, making it worthy of promotion.

[0025] Specifically, each of the sealing mechanisms 9 includes several limiting plates 91, rubber sealing rings 92, and annular grooves 93. The annular grooves 93 are disposed on the inner sidewall of the corresponding disassembly plate 3. The limiting plates 91 are fixedly disposed in a circular equidistant array on the sidewall of the first turbine 5. The rubber sealing rings 92 are fixedly disposed on the top of the disassembly plate 3. When the disassembly plate 3 rotates, the external thread 41 and the internal thread 42 engage, resulting in relative axial movement. The movement of the disassembly plate 3, under the action of the annular grooves 93, drives the limiting plates 91 to move. The movement of the limiting plates 91 drives the first turbine 5 to move. The movement of the first turbine 5 causes the triangular block 73 to engage with the triangular groove 72. The movement of the limiting plates 91 causes the two disassembly plates 3 to compress the rubber sealing rings 92, causing the rubber sealing rings 92 to deform and seal the two disassembly plates 3. This ensures the sealing between the disassembly plates 3, maintains the suction of the water inlet 2, and reduces wear between the disassembly plates 3 through the rubber material, increasing the service life of the device.

[0026] Specifically, each of the disassembly plates 3 has an arc-shaped groove at its bottom for the rubber sealing ring 92 to engage, and each of the limiting plates 91 is located within the corresponding annular groove 93 for limiting sliding.

[0027] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
