Description

Technical Field

[0001] This invention relates to the field of shielded pump technology, specifically a high-sealing shielded pump. Background Technology

[0002] Ordinary centrifugal pumps are driven by connecting the pump impeller shaft to the motor shaft via a coupling, causing the impeller and motor to rotate together. In contrast, canned motor pumps are sealless pumps, where both the pump and the drive motor are sealed within a pressure vessel filled with the pumped medium. This pressure vessel has only a static seal, and a wiring harness provides the rotating magnetic field to drive the rotor. This structure eliminates the rotating shaft sealing device found in traditional centrifugal pumps, thus achieving complete leak-free operation. In existing technologies, canned motor pumps use their own power to drive flowing water into the interior for cooling. However, the flowing water easily carries contaminants into the interior, causing them to cover the surface. At the same time, the cooling water flow rate is relatively slow, resulting in less than ideal cooling efficiency and effect.

[0003] For example, patent publication number CN217926474U describes a high-power canned motor pump. This high-power canned motor pump has a reasonable structural design and can use flowing water circulation to dissipate heat, improving heat dissipation efficiency, avoiding affecting the operating efficiency of the high-power canned motor pump, reducing resonance between the high-power canned motor pump and the ground, preventing loosening of internal parts, preventing damage to the high-power canned motor pump, and extending the service life of the high-power canned motor pump. However, this type of canned motor pump uses its own power to drive flowing water into the interior for cooling, but the flowing water can easily carry pollutants into the interior, causing them to cover the surface. At the same time, the cooling water flow rate is relatively slow, resulting in less than ideal cooling efficiency and cooling effect.

[0004] For example, patent publication number CN218862874U describes a canned motor pump. This utility model, through the design of the installation components, allows for the quick and easy installation of the connecting seat onto the fixed plate, improving installation efficiency and automation. This solves the problem that existing canned motor pumps are often installed manually by tightening bolts, which is time-consuming and labor-intensive. The heat dissipation components facilitate heat dissipation from the pump body, ensuring its normal service life. However, this type of canned motor pump uses its own power to drive flowing water into the interior for cooling. The flowing water can easily carry contaminants into the interior, causing them to cover the surface. Additionally, the slow flow rate of the cooling water results in less than ideal cooling efficiency and effect. Summary of the Invention

At the same time, the motor shaft 9 drives the first driving bevel gear 203 to rotate, which in turn drives the first driven bevel gear 208 to rotate. The first driven bevel gear 208 then drives the first connecting shaft 207 to rotate, which in turn drives the first gear 206 to rotate. The rotation of the first gear 206 drives the rotating ring 204 to rotate through multiple drive teeth 205. The rotation of the rotating ring 204 drives multiple actuating blocks 209 to move, which in turn pushes the movable brush 214 to move.

[0040] Please see Figure 1 and Figure 6The discharge cover 7 includes a movable cover 701. Two rotating shafts 702 are fixedly connected to both sides of one end of the movable cover 701. The movable cover 701 is rotatably connected to the bottom end of the outer frame 201 through the rotating shafts 702, so that the movable cover 701 can rotate along the rotating shafts 702. A groove 703 is provided at the end of the movable cover 701 away from the rotating shafts 702. A movable block 704 is slidably connected to the inner wall of the groove 703. A fixing block 705 is fixedly connected to one end of the movable block 704. A third spring 706 is provided at the other end of the movable block 704, which can play a resetting role for the movable block 704. A sealing strip is provided between the movable cover 701 and the outer frame 201 to increase the overall sealing effect and prevent leakage.

The shock-absorbing pad 805 is connected to the pump body. 1. Fixed connection: Both ends of the two adjusting screws 807 are fixedly connected to driven sprockets 810, and the end of the adjusting block 808 is fixedly connected to a driving sprocket 809. A transmission chain 811 is sleeved between the driving sprocket 809 and the two driven sprockets 810, so that the adjusting block 808 can drive the two adjusting screws 807 to rotate simultaneously through the driving sprocket 809, the driven sprocket 810 and the transmission chain 811. The rotation of the adjusting screws 807 drives the movable guide frame 806 to slide along the inner wall of the guide seat 803, thereby adjusting the height of the pump body 1, adapting to different installation environments and effectively improving the flexibility and convenience of installation.

[0042] In use, the water filter screen 212 filters the cooling water. Simultaneously, the motor shaft 9 drives the first driving bevel gear 203 to rotate, which in turn drives the first driven bevel gear 208 to rotate. The driven bevel gear 208 then drives the first connecting shaft 207 to rotate, which in turn drives the first gear 206 to rotate. The rotation of the first gear 206, through multiple drive teeth 205, drives the rotating ring 204 to rotate. The rotating ring 204 then drives multiple actuating blocks 209 to move. The actuating blocks 209 push the movable rotating block 2142 and the cleaning brush 2141 to move, cleaning the water filter screen 212. When the brush reaches the end of the guide groove 213, the movable brush 214 is obstructed and cannot move further. The actuating blocks 209 then push the movable rotating block 2142 to rotate, causing the movable rotating block 2142 to separate from the actuating blocks 209. Finally, the first spring 215 presses against the movable brush 214. Upon reset, the second spring 2144 resets the movable rotating block 2142, allowing the toggle block 209 to push the movable brush 214 to move and clean again. This continuously drives the movable brush 214 to reciprocate, cleaning the surface of the filter screen 212 and preventing contaminants from adhering and causing blockage. Simultaneously, the rotating ring 204 drives multiple drive teeth 205 to rotate, which in turn drives the second gear 301 to rotate. The second gear 301 then drives the second connecting shaft 302 to rotate, which in turn drives the second driving bevel gear 303 to rotate. The second driving bevel gear 303 then drives the second driven bevel gear 304 to rotate, which in turn drives the third connecting shaft 305 to rotate. The third connecting shaft 305 then drives the accelerating paddle 306 to rotate, providing a horizontal pushing and accelerating effect on the water flow, effectively improving cooling efficiency and heat dissipation.
