Description

Technical Field

[0001] The utility model relates to the technical field of submersible pumps, in particular to a submersible pump that is convenient for installation. Background Art

[0002] The motor and the pump are integrated, eliminating the need for complex on-site axial alignment installation procedures, saving installation time and labor costs. For example, some stainless steel submersible pumps adopt this integrated design, with a compact structure, small size, convenient installation, and are suitable for underwater work at various depths.

[0003] Some submersible pumps in the prior art are water-lifting machines with the motor directly connected to the pump and integrated to work underwater. Before starting the pump, the suction pipe and the pump must be filled with liquid. After starting the pump, the impeller rotates at high speed, and the liquid therein rotates with the blades. Under the action of centrifugal force, it flies away from the impeller and shoots outwards. The speed of the ejected liquid gradually slows down in the diffusion chamber of the pump housing, and the pressure gradually increases, and then flows out from the pump outlet and the discharge pipe. However, in the specific use process, there is no good sealing and angle adjustment function, and the connection between the submersible pump and the pipeline is prone to looseness during operation. This will cause unnecessary vibration in the whole system, which will not only generate noise, but also damage the surrounding equipment and structures. Long-term vibration causes the fixing components of the submersible pump to loosen, affecting its normal working life and even posing a safety hazard. Therefore, in view of the above problems, a submersible pump that is convenient for installation is proposed. Summary of the Utility Model

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figures 1 to 3, Submersible pump for easy installation, including a pump body 1. The pump body 1 is cylindrical, made of strong metal material, with its surface specially treated, having good corrosion resistance and wear resistance. Its internal structure is precise, including key components such as an impeller and a motor, and can efficiently transport water from a lower place to a higher place. The outside of the pump body 1 is fixedly connected with a fixing ring 2. The fixing ring 2 is usually made of high-strength steel, in a circular shape, having a certain thickness and width, and can provide stable support for the pump body. The outside of the fixing ring 2 is fixedly connected with a plurality of connecting blocks 3. The connecting blocks 3 are generally in the shape of a cuboid, made of strong cast iron material. One end of it is welded to the fixing ring 2, with a firm and reliable connection, and the other end extends upward to provide support for the fixing rod 4. The top of the connecting block 3 is fixedly connected with a fixing rod 4. The fixing rod 4 is usually a slender cylinder, made of stainless steel material, having high strength and corrosion resistance. The function of the fixing rod 4 is to fix the pump body at a specific position during the installation of the submersible pump, preventing it from moving during the working process. The bottom of the pump body 1 is fixedly connected with a waterproof housing 5. The waterproof housing 5 is hemispherical, made of high-strength plastic material, having good waterproof performance. It can effectively protect components such as the motor inside the pump body from water erosion, ensuring the normal operation of the submersible pump. The outside of the waterproof housing 5 is fixedly connected with a docking pipe 7. The docking pipe 7 is a cylindrical pipe, made of corrosion-resistant metal material. Its length is appropriate, and its diameter matches that of the delivery pipe 12, and can ensure the smooth flow of water through it;

[0032] The exterior of the docking pipe 7 is finely polished, with a smooth surface, reducing the resistance of water flow. A docking component for pipe docking is fixedly connected to the exterior of the docking pipe 7. The docking component includes a flange 6. The flange 6 is circular and made of thick steel. Multiple evenly arranged bolt holes are distributed on its surface. Through these bolt holes, bolts can be used to firmly connect the docking pipe to other pipes. The edge of the flange 6 is chamfered to avoid harming the operators during installation. A plurality of bolts are fixedly connected to the exterior of the flange 6. The bolts are usually made of high-strength alloy steel, having good tensile strength and corrosion resistance. The head of the bolt is hexagonal, facilitating the tightening operation with a wrench. The thread of the bolt is fine, ensuring the firmness of the connection. The exterior of the flange 6 is fixedly connected to the exterior of the docking pipe 7. The exterior of the docking pipe 7 is threadedly connected with a locking ring 9. The locking ring 9 is circular and made of stainless steel. Its interior is provided with a thread matching the docking pipe 7. By rotating the locking ring 9, the delivery pipe 12 can be tightly fixed to the docking pipe 7, preventing water leakage during operation. A sealing ring I 8 is fixedly connected to the interior of the docking pipe 7. The sealing ring I 8 is usually made of rubber material, having good elasticity and sealing performance. It can effectively prevent water from leaking out at the connection between the docking pipe 7 and the delivery pipe 12, ensuring the normal operation of the submersible pump. A sphere I 10 is fixedly connected to the top of the docking pipe 7. A sphere II 11 is rotatably connected to the interior of the sphere I 10. The sphere II 11 is also hemispherical and has the same material as the sphere I 10. The design of the sphere I 10 and the sphere II 11 enables the delivery pipe 12 to rotate freely within a certain angle range, facilitating installation and adjustment. A delivery pipe 12 is fixedly connected to the exterior of the sphere II 11. The delivery pipe 12 is a cylindrical pipe made of corrosion-resistant plastic material. Its diameter matches that of the docking pipe 7, ensuring smooth water flow transportation. The surface of the delivery pipe 12 is smooth, reducing the resistance of water flow and improving the working efficiency of the submersible pump;

[0033] Refer to Figures 3 to 4 , a sealing ring II 13 is fixedly connected to the interior of the delivery pipe 12. The sealing ring II 13 is usually made of rubber material with good elasticity and is circular. Its thickness is appropriate, enabling it to closely fit the exterior of the connecting plate 14, effectively preventing water from leaking at the connection between the connecting plate 14 and the delivery pipe 12. A connecting plate 14 is slidably connected to the interior of the sealing ring II 13. The function of the connecting plate 14 is to play a certain buffering role when water flows through or cooperate with other components to achieve specific functions. A connecting plate 16 is fixedly connected to the interior of the delivery pipe 12. The connecting plate 16 is a circular flat plate made of strong metal material. Its diameter matches the inner diameter of the delivery pipe 12 and is firmly fixed to the interior of the delivery pipe 12 by welding or other means. The connecting plate 16 is provided with a sliding hole matching the sliding rod 15, ensuring that the sliding rod 15 can slide stably therein;

[0034] A sliding rod 15 is slidably connected inside the connecting plate 16. The sliding rod 15 is a slender cylinder made of stainless steel. Its diameter is slightly smaller than the diameter of the sliding hole on the connecting plate 16, and it can slide freely up and down in the sliding hole. A spring 17 is sleeved outside the sliding rod 15. The spring 17 is usually made of high-strength spring steel and is spiral. The elasticity of the spring 17 is moderate. It can deform when subjected to an external force and quickly return to its original state when the external force disappears. A limiting block 18 is fixedly connected to the top end of the sliding rod 15. The limiting block 18 is a circular block made of metal. Its diameter is larger than the diameter of the sliding rod 15, and it can prevent the sliding rod 15 from slipping out of the connecting plate 16. The bottom of the waterproof housing 5 is fixedly connected with a mounting seat 19. The bottom of the mounting seat 19 is fixedly connected with a plurality of rivets 20. The mounting seat 19 is in the shape of a cuboid and is made of strong metal. Its surface is treated with rust prevention and has good corrosion resistance. A plurality of mounting holes are provided on the mounting seat 19, and the submersible pump is fixed at a specific position through the rivets 20. Fixed blocks 21 are fixedly connected to both the left and right sides of the top of the pump body 1. A pull ring 22 is fixedly connected to the outside of the fixed block 21. The pull ring 22 is a circular ring made of stainless steel. Its diameter is moderate, which is convenient for the operator to hold by hand. The surface of the pull ring 22 is polished, smooth and bright. It is not only beautiful and generous, but also not easy to scratch the operator's hand during use. One end of the spring 17 is fixedly connected to the outside of the connecting plate 16, and the other end of the spring 17 is fixedly connected to the outside of the connecting plate 14.

[0035] Working principle: First, the pump body 1 of the submersible pump is fixed at a specific position. The fixed ring 2 and the connecting block 3 provide stable support to ensure that the pump body does not move during operation. The motor and impeller inside the pump body start to operate. The motor drives the impeller to rotate, thereby generating negative pressure to suck water from a lower place. The water flow enters the waterproof housing 5 through the bottom of the pump body 1. The waterproof housing 5 effectively protects key components such as the internal motor from being eroded by water.

[0036] Subsequently, by rotating the sphere two 11, its material is the same as that of the sphere one 10. The design of the sphere one 10 and the sphere two 11 enables the conveying pipe 12 to rotate freely within a certain angle range, which is convenient for installation and adjustment. The water flow enters the conveying pipe 12 through the docking pipe 7. The surface of the docking pipe 7 is finely polished to reduce the resistance of the water flow and ensure that the water flow passes through smoothly without obstruction.

[0037] During the transportation process, the design of the first seal ring 8 and the second seal ring 13 ensures that water does not leak at the connection, maintaining the tightness of the system. When the water flow passes through the connecting plate 16, the sliding rod 15 can freely slide up and down under the action of the spring 17, playing a role in buffering and regulating the water flow. Under the push of the water flow, the movement of the sliding rod 15 is restricted within the sliding hole of the connecting plate 16 to ensure its stability. The water flow passes through the delivery pipe 12 and is finally delivered to the required high place or specific position. After the water flow stops, the spring 17 will automatically reset, thereby preventing the water flow from flowing back.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. 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 perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
