Description

Technical Field

[0001] This application relates to the field of submersible pump equipment, and more particularly to a submersible pump with a quick-release structure. Background Technology

[0002] A submersible pump is a fluid transport device that operates by immersing the pump body and motor entirely in liquid. It is widely used in agricultural irrigation, industrial drainage, municipal flood control, sewage treatment, reservoir water diversion, and deep well pumping. A submersible pump typically consists of a motor, pump casing, impeller, bearing assembly, sealing structure, cable connection, and mounting bracket. The impeller, as the core component for liquid transport, plays a crucial role in converting the motor's rotational power into the liquid's kinetic energy. During long-term operation, the impeller is highly susceptible to wear, jamming, deformation, or corrosion damage due to sand, impurities, or corrosive substances entrained in the transported medium. This can affect the pump's flow rate, head, and efficiency, and even lead to motor overload or burnout. Therefore, regular impeller replacement and cleaning are critical tasks in the maintenance and repair of submersible pumps.

[0003] Most existing submersible pumps use traditional bolt fixing or key connection methods for impeller installation. When disassembling the impeller, it is often necessary to lift the entire pump body out of the water first, which is a cumbersome, time-consuming and labor-intensive process. Moreover, since submersible pumps are usually installed at the bottom of wells, sump pits or underwater equipment rooms, the working environment is narrow and the operating space is limited, resulting in low impeller replacement efficiency and high maintenance costs.

[0007] Furthermore, the submersible pump with quick-release structure also includes a rotating shaft and an elastic buffer; the rotating shaft passes through the second connecting part; the elastic buffer is sleeved on the outside of the rotating shaft and abuts against the elastic buckle, for applying a squeezing force to the buckle when the rotating shaft vibrates.

[0012] This technical solution clarifies the specific functions and integration methods of each part of the pump body assembly, making the overall structure of the submersible pump clearer and more reasonable.

[0013] Furthermore, in this submersible pump with a quick-release structure, two elastic snap-fit ​​components are symmetrically arranged on the second connecting part.

Detailed implementation method: The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of this application.

[0031] See Figures 1 to 3 This embodiment discloses a submersible pump with a quick-release structure, which aims to simplify the disassembly and assembly process of the submersible pump and improve maintenance efficiency. Traditional submersible pumps typically use bolts or key connections for impeller installation and disassembly. This often requires lifting the entire pump body out of the underwater environment when the impeller needs repair or replacement, resulting in low efficiency and high costs. To address this, this application proposes a submersible pump with a quick-release structure. The pump body assembly is designed as a first and second connecting part that can be separated from each other. The inner wall of the first connecting part has an annular groove 4, while the second connecting part has an elastic locking element 6. This elastic locking element 6 cleverly integrates a button 61, a locking block 62, and a spring 63. The locking block 62 engages with the annular groove 4 to achieve a quick and reliable connection between the two connecting parts, and the button 61 is pressed to achieve quick separation.

[0032] The core of this submersible pump lies in the design of its pump body assembly, which is constructed as a first connecting part and a second connecting part that can be separated from each other. The first connecting part typically refers to the upper part or outer casing of the pump body, and its internal structure is designed to connect with the second connecting part. The second connecting part typically refers to the lower part or internal functional component part of the pump body. To achieve quick connection and separation of the two parts, an annular groove 4 is provided on the inner wall of the first connecting part. This annular groove 4 is a continuous ring structure, and its function is to provide a stable engagement position for the latch. An elastic latch 6 is provided on the second connecting part. The elastic latch 6 is an integrated mechanical device that includes a button 61, a latch block 62, and a spring 63. The button 61 is used to trigger the release of the latch; the latch block 62 is the component that actually performs the engagement and disengagement action, and its shape and size are designed to precisely fit with the annular groove 4; the spring 63 provides preload to the latch block 62, ensuring that it can firmly maintain engagement with the annular groove 4 under normal conditions.

[0033] On the second connecting part, see Figure 3 , Figure 4 and Figure 5 The device is equipped with an elastic latching component 6. This elastic latching component 6 is the core component for achieving the quick-release function. Its internal structure is ingenious, including a button 61, a latching block 62, and a spring 63. Specifically, the latching block 62 is the component that directly engages with the annular groove 4. When the first connecting part and the second connecting part are connected, the latching block 62, driven by the spring 63, automatically extends and enters the annular groove 4, thereby firmly connecting the first and second connecting parts together. The latching block 62 can be designed in a wedge shape, rectangle, or with chamfered edges to facilitate smooth entry and exit from the annular groove 4. The function of the spring 63 is to provide a continuous driving force to the latching block 62, ensuring it always tends to maintain engagement with the annular groove 4. The spring 63 can be a compression spring, torsion spring, or leaf spring, as long as it provides sufficient preload. When it is necessary to separate the first and second connecting parts, the user simply presses the button 61. When the button 61 is pressed, it moves the latching block 62 inward, disengaging it from the annular groove 4. Once the locking block 62 is completely disengaged from the annular groove 4, the first connecting part and the second connecting part can be easily separated from each other.

[0034] When assembling the first and second connecting parts of the submersible pump, simply insert the second connecting part into the first connecting part. During this process, the locking block 62 of the elastic latch 6 on the second connecting part will first contact the inner wall of the first connecting part. Since the locking block 62 is in an outward-extending state driven by the spring 63, it will be squeezed and temporarily retract inward when it contacts the inner wall of the first connecting part. As the second connecting part continues to go deeper, when the locking block 62 aligns with the annular groove 4 on the inner wall of the first connecting part, the elastic force of the spring 63 will immediately drive the locking block 62 to pop outward, making it firmly locked into the annular groove 4. At this time, the locking block 62 and the annular groove 4 form a stable mechanical engagement, thereby reliably connecting the first and second connecting parts together and preventing them from accidentally separating during the operation of the submersible pump.

[0035] In some embodiments described above, the submersible pump body assembly achieves quick connection and separation via a snap-fit ​​element 6 and annular groove 4. However, during actual operation of the submersible pump, internal rotating components, particularly the rotating shaft 7, inevitably vibrate at high speeds. This vibration may adversely affect the stability of the snap-fit ​​between the snap-fit ​​element 6 and the annular groove 4, and in extreme cases, may even lead to loosening or accidental disengagement, thereby affecting the normal operation and safety of the submersible pump. Therefore, this application further proposes optimizing the connection structure to enhance its connection reliability under vibration conditions.

[0036] Specifically, the submersible pump of this application further includes a rotating shaft 7 and an elastic buffer 9. The rotating shaft 7 is the core component inside the submersible pump used to drive the impeller rotation, and it is installed within the second connecting portion. The elastic buffer 9 is an elastic member that is sleeved on the outside of the rotating shaft 7 and configured to abut against the elastic snap-fit ​​member 6.

[0037] The solution proposed in this application effectively solves the connection stability problem that may be caused by the vibration of the rotating shaft 7 during operation of the submersible pump by introducing an elastic buffer 9. When the rotating shaft 7 vibrates at high speed, this vibration is transmitted to the elastic buffer 9 fitted outside it. Since the elastic buffer 9 abuts against the elastic snap-fit ​​6, especially the snap-fit ​​block 62, when the elastic buffer 9 is subjected to the vibration of the rotating shaft 7, it will deform and apply a continuous compressive force to the snap-fit ​​block 62. This compressive force can effectively offset or reduce the adverse effects of vibration on the engagement force between the snap-fit ​​block 62 and the annular groove 4, thereby ensuring that the snap-fit ​​block 62 always maintains a tight and stable engagement with the annular groove 4. It is precisely because of the buffering and compressive effect of the elastic buffer 9 that the quick-release structure of the submersible pump can maintain a high degree of connection reliability even in dynamic working environments.

[0038] In some preferred embodiments, the elastic buffer 9 can be designed as an annular rubber washer with an inner diameter slightly larger than the outer diameter of the rotating shaft 7 for easy fitting. The outer diameter of the rubber washer is designed to make close contact with the inner wall of the elastic snap-fit ​​6 or a specific part of the snap block 62. When the rotating shaft 7 rotates and vibrates, the rubber washer vibrates slightly and undergoes elastic deformation. The reaction force generated by this deformation continuously acts on the snap block 62, causing it to be stably pushed into the annular groove 4, thereby ensuring the secure engagement. Furthermore, to further optimize the buffering effect, the hardness, thickness, and contact area with the rotating shaft 7 and the elastic snap-fit ​​6 of the elastic buffer 9 can be precisely designed and adjusted according to the actual vibration characteristics and the required buffering effect.

[0039] In some embodiments described above, a submersible pump with a quick-release structure is provided. However, in practical applications, relying solely on mechanical connections may not completely prevent liquid leakage at the connection between the first and second connecting parts, especially in the operating environment of the submersible pump, where sealing is crucial for reliable operation. Therefore, this application further proposes a solution to enhance sealing performance by providing a sealing ring 5 at the connection.

[0040] The sealing ring 5 refers to a ring-shaped or gasket-shaped component used to prevent fluid leakage, which is usually made of elastic material, such as rubber, silicone or fluororubber.

[0041] The solution of this application effectively solves the potential leakage problem at the connection point by introducing a sealing ring 5 between the first connecting part and the second connecting part. When the first connecting part and the second connecting part are connected, the sealing ring 5 is clamped and compressed between them, and its elastic deformation creates a gapless seal at the connection interface. Since the sealing ring 5 is located below the locking block 62, it is closer to the fluid channel, allowing for more direct prevention of fluid penetration. Simultaneously, the locking action of the locking block 62 indirectly assists in the fixation and compression of the sealing ring 5, ensuring the stability of the seal.

[0042] Based on the above-described embodiments of this application, the first connecting part is mainly responsible for guiding the fluid flow. The design of its internal outlet 1 and inlet 11 effectively guides the fluid to flow in a predetermined direction, improving the efficiency of fluid transport. Specifically, the inlet 11 can be located at the lower part of the first connecting part to facilitate the intake of fluid from the water, while the outlet 1 can be located at the upper or side part of the first connecting part to facilitate the discharge of fluid. The second connecting part integrates key components such as the motor 10, the rotating shaft 7, and the impeller 3. The motor 10 serves as a power source, driving the rotating shaft 7 to rotate, while the impeller 3, fixed on the rotating shaft 7, generates centrifugal force through rotation, thereby achieving fluid suction and transport.

[0043] In the submersible pump of this application, the first connecting part and the second connecting part can be quickly disassembled through the cooperation of the elastic snap fastener 6 and the annular groove 4. Furthermore, in order to ensure the stable operation of the rotating shaft 7 and avoid its vibration from adversely affecting the elastic snap fastener 6, this application proposes an optimized structural design, namely, setting a fastener 8 in the second connecting part and placing an elastic buffer 9 between the fastener 8 and the elastic snap fastener 6.

[0044] The fastener 8 serves to fix the rotating shaft 7, reducing its radial and axial movement and thus lowering the vibration amplitude. The elastic buffer 9 is used to absorb the residual vibration transmitted by the rotating shaft 7, preventing the locking block 62 from accidentally loosening due to vibration and ensuring the reliability of the connection between the first and second connecting parts.

[0045] In a preferred embodiment, the fastener 8 can be fixed inside the second connecting part using screws, snap rings, or similar means, while the elastic buffer 9 can be made of materials with good elasticity and damping properties, such as rubber or silicone. During actual assembly, the rotating shaft 7 is first installed into the second connecting part, and then the fastener 8 is fixed to provide effective support and constraint for the rotating shaft 7. Subsequently, the elastic buffer 9 is fitted over the rotating shaft 7, with one end abutting against the fastener 8 and the other end abutting against the elastic clip 6. In this way, the vibration of the rotating shaft 7 can be effectively transmitted to the elastic buffer 9, which absorbs and attenuates the vibration energy, thereby protecting the elastic clip 6 from vibration.

[0046] The above description is merely an embodiment of this application and is not intended to limit the scope of protection of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
