Description

Technical Field

[0001] This utility model belongs to the field of submersible pump technology, specifically relating to a submersible pump anti-dry burning device and a submersible pump. Background Technology

[0002] Submersible pumps are essential equipment for deep well water extraction. During operation, the entire unit is submerged in water to extract groundwater to the surface. They are used for domestic water supply, mine rescue operations, industrial cooling, farmland irrigation, seawater lifting, ship ballast adjustment, and even for fountain landscaping. A submersible pump unit consists of four main parts: a water pump, a submersible motor (including cables), water delivery pipes, and control switches. The submersible pump is a single-suction, multi-stage vertical centrifugal pump; the submersible motor is a sealed, water-filled, wet-type, vertical three-phase squirrel-cage asynchronous motor, directly connected to the pump via a claw-type or single-key cylinder coupling; it is equipped with three-core cables of different specifications; the starting equipment includes air switches and autotransformer pneumatic actuators of different capacity levels; the water delivery pipes are made of steel pipes of different diameters, connected by flanges; high-lift pumps use gate valve control.

[0003] In actual production, when a submersible pump pumps water to a low level, the pump motor will be exposed above the water surface. At this time, because the water level is too low, the pump motor cannot be fully immersed in the external water, resulting in the motor not being able to cool down, which leads to the phenomenon of dry burning and pump burnout. This needs to be improved. Therefore, it is of great importance to design a submersible pump anti-dry burning device and a submersible pump to solve the above defects. Utility Model Content

[0004] (1) Technical problems to be solved

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a submersible pump anti-dry burning device and a submersible pump. The connecting shell body solves the problem that under the prior art, the submersible pump motor part cannot be fully immersed in external water, resulting in the motor not being able to cool down, and thus the phenomenon of dry burning and pump burning occurs.

[0006] (2) Technical solution

[0007] To solve the above-mentioned technical problems, this utility model provides a submersible pump anti-dry burning device, which includes a connecting shell body; a conveying pipe is provided on the outside of the connecting shell body, a conveying component is provided inside the connecting shell body, a fixed shell is fixedly connected to the bottom of the connecting shell body, and a connecting component is provided inside the fixed shell.

[0008] The conveying assembly is used to process the water flow conveyed by the conveying pipe. The conveying assembly includes a rotating frame rotatably connected inside the main body of the connecting shell. Multiple sets of nozzles are fixedly connected to both ends inside the rotating frame. A connecting pipe is fixedly connected to the top of the rotating frame, and a fixed pipe is rotatably connected to the top of the connecting pipe.

[0009] The connecting assembly is used to mount the connecting housing body onto the outside of the submersible pump.

[0010] When using the connecting shell body of this technical solution, place the connecting shell body on the outside of the submersible pump, rotate the rotating block to drive the worm gear to rotate, which in turn drives the drive screw to rotate, thereby displacing the moving frame and the clamping plate. The clamping plate then contacts the outside of the submersible pump. The two sets of clamping plates allow the fixed shell to be installed with the submersible pump, thus installing the connecting shell body on the outside of the submersible pump. Start the small water pump to guide the water flow from the bottom outside of the submersible pump into the delivery pipe, allowing the water flow to enter the fixed pipe, and then into the connecting pipe. The water flow is then directed into the cavity inside the rotating frame, where it is sprayed out through multiple nozzles. Start the drive motor to drive the second synchronous pulley to rotate, which in turn drives the first synchronous pulley to rotate via the synchronous belt, causing the connecting pipe to rotate and the rotating frame to rotate. This causes the multiple nozzles to rotate and shift around the rotating frame as the center, achieving all-around cooling of the submersible pump and increasing the spray cooling effect.

[0011] Preferably, the top of the fixed pipe is rotatably connected to the delivery pipe, and a small water pump is fixedly connected to the bottom of the delivery pipe.

[0012] Furthermore, a mounting shell is fixedly connected to the top of the main body of the connecting shell, and both the fixing tube and the connecting tube are rotatably connected to the mounting shell, while the connecting tube is rotatably connected to the main body of the connecting shell.

[0013] Furthermore, the connecting pipe extends into the interior of the mounting housing and is fixedly connected to a first synchronous pulley. A synchronous belt is provided on the outer side of the first synchronous pulley, and a second synchronous pulley is provided at the end of the synchronous belt away from the first synchronous pulley.

[0014] Furthermore, a drive motor is fixedly connected to the top of the mounting housing, and the drive end of the drive motor extends into the interior of the mounting housing and is fixedly connected to the second synchronous pulley.

[0015] Furthermore, the connecting assembly includes clamping plates slidably connected to both ends inside the fixed housing, with movable frames fixedly connected to the outer side of the clamping plates, and drive screws rotatably connected to both sides inside the fixed housing and inside the two sets of movable frames.

[0016] Furthermore, the drive screw is threadedly connected to the moving frame, and a worm gear is fixedly connected to the end of the drive screw away from the moving frame. A worm is meshed with the outer side of the worm gear, and a rotating block is fixedly connected to the top of the fixed housing.

[0017] The present invention provides a submersible pump, including a submersible pump anti-dry-burning device.

[0018] (3) Beneficial effects

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] 1. The main body of the connecting shell of this utility model, through the design of the conveying component, drives the motor to drive the first synchronous pulley to rotate via the second synchronous pulley and synchronous belt, thereby driving the connecting pipe and the rotating frame at the bottom to rotate synchronously. This causes multiple sets of nozzles at both ends of the rotating frame to make circular motion around the rotating frame as the center. This rotating spraying method can cover the entire outer perimeter of the submersible pump motor, avoiding the problem of traditional fixed spraying only cooling a local area and causing the uncooled area to dry out due to high temperature. It fundamentally solves the problem of blind spots in motor cooling. The small water pump at the bottom of the conveying pipe can actively guide the water flow from the outside of the bottom of the submersible pump into the conveying pipe, and then transport it through the fixed pipe and connecting pipe to the cavity inside the rotating frame. Finally, it is evenly sprayed out through the nozzles, avoiding the risk of cooling water interruption and motor overheating due to low liquid level.

[0021] 2. The main body of the connecting shell of this utility model, through the design of the connecting components, only requires manual rotation of the rotating block on the top of the fixed shell to drive the drive screw to rotate through the transmission chain of the rotating block, worm, worm wheel and drive screw. Since the drive screw is threadedly connected to the moving frame, when the screw rotates, it will drive the moving frame and the outer clamping plate to slide along the inside of the fixed shell, so as to achieve the contact or separation of the clamping plate with the outside of the submersible pump. The entire installation process does not require the use of wrenches or other tools, making the operation simple and efficient and reducing the threshold for users. Attached Figure Description

[0030] This specific embodiment is a submersible pump anti-dry-burning device, and its structural schematic diagram is shown below. Figure 1-7 As shown, the dry burning device includes a connecting shell body 1; a conveying pipe 2 is provided on the outside of the connecting shell body 1, a conveying assembly 3 is provided inside the connecting shell body 1, a fixed shell 4 is fixedly connected to the bottom of the connecting shell body 1, and a connecting assembly 5 is provided inside the fixed shell 4.

[0031] The conveying assembly 3 is used to output the water flow conveyed by the conveying pipe 2. The conveying assembly 3 includes a rotating frame 6 rotatably connected to the inside of the connecting shell body 1. Multiple sets of nozzles 7 are fixedly connected to both ends inside the rotating frame 6. A connecting pipe 8 is fixedly connected to the top of the rotating frame 6. A fixed pipe 9 is rotatably connected to the top of the connecting pipe 8.

[0032] The connecting assembly 5 is used to mount the connecting housing body 1 on the outside of the submersible pump.

[0033] In this embodiment, the top of the fixed pipe 9 is rotatably connected to the delivery pipe 2, and the bottom of the delivery pipe 2 is fixedly connected to a small water pump 10. The interior of the rotating frame 6 is provided with a cavity, which is connected to multiple sets of nozzles 7. When the small water pump 10 is started, the water flow outside the bottom of the submersible pump is introduced into the interior of the delivery pipe 2, so that the water flow can be introduced into the interior of the fixed pipe 9, thereby introducing the water flow into the interior of the connecting pipe 8, so that the water flow is introduced into the cavity inside the rotating frame 6, and the water flow is sprayed out through multiple sets of nozzles 7.

[0034] Secondly, in this embodiment, a mounting shell 11 is fixedly connected to the top of the connecting shell body 1. The fixing tube 9 and the connecting tube 8 are rotatably connected to the mounting shell 11. The connecting tube 8 is rotatably connected to the connecting shell body 1. The fixing tube 9 and the connecting tube 8 are rotatably connected to the mounting shell 11. When the fixing tube 9 and the connecting tube 8 rotate, the mounting shell 11 can guide them and increase the stability of the rotation.

[0035] In addition, in this embodiment, the connecting pipe 8 extends into the interior of the mounting shell 11 and is fixedly connected to a first synchronous pulley 12. A synchronous belt 13 is provided on the outer side of the first synchronous pulley 12. A second synchronous pulley 14 is provided at the end of the synchronous belt 13 away from the first synchronous pulley 12. A drive motor 15 is fixedly connected to the top of the mounting shell 11. The drive end of the drive motor 15 extends into the interior of the mounting shell 11 and is fixedly connected to the second synchronous pulley 14. When the drive motor 15 is started, it drives the second synchronous pulley 14 to rotate. The first synchronous pulley 12 rotates through the synchronous belt 13, which drives the connecting pipe 8 to rotate, which causes the rotating frame 6 to rotate. This causes multiple sets of nozzles 7 to rotate and move around the rotating frame 6 as the center, thereby achieving all-round cooling of the submersible pump and increasing the spray cooling effect.

[0036] Furthermore, in this embodiment, the connecting assembly 5 includes clamping plates 16 slidably connected to both ends inside the fixed housing 4. A movable frame 17 is fixedly connected to the outer side of the clamping plate 16. A drive screw 18 is rotatably connected to both sides inside the fixed housing 4 and inside the two sets of movable frames 17. The drive screw 18 is threadedly connected to the movable frame 17. A worm gear 19 is fixedly connected to the end of the drive screw 18 away from the movable frame 17. A worm 20 is meshed with the outer side of the worm gear 19. A rotating block 21 is fixedly connected to the top of the fixed housing 4. When the submersible pump needs to be cooled, the connecting housing body 1 is placed outside the submersible pump. The rotating block 21 is rotated, which drives the worm 20 to rotate, causing the worm gear 19 to rotate, which in turn drives the drive screw 18 to rotate, thereby causing the movable frame 17 to move and the clamping plate 16 to move, so that the clamping plate 16 contacts the outer side of the submersible pump. The fixed housing 4 and the submersible pump are installed through the two sets of clamping plates 16, thereby installing the connecting housing body 1 on the outer side of the submersible pump.

[0037] The present invention provides a submersible pump, including the submersible pump anti-dry-burning device provided in any of the above embodiments. Because it has all the technical features of the submersible pump anti-dry-burning device provided in any of the above embodiments, it has the same technical effect as the above-mentioned submersible pump anti-dry-burning device.

[0038] When using the device of this technical solution, when cooling of the submersible pump is required, the connecting shell body 1 is placed on the outside of the submersible pump. Rotating the rotating block 21 drives the worm gear 20 to rotate, causing the worm wheel 19 to rotate, which in turn drives the drive screw 18 to rotate. This causes the moving frame 17 to shift, which in turn shifts the clamping plate 16, bringing it into contact with the outside of the submersible pump. The two sets of clamping plates 16 then install the fixed shell 4 onto the submersible pump, thus installing the connecting shell body 1 on the outside of the submersible pump. The small water pump 10 is then started, guiding the water flow from the outside of the bottom of the submersible pump into the interior of the delivery pipe 2, allowing the water to cool down. The water flow can be introduced into the interior of the fixed pipe 9, thereby guiding the water flow into the interior of the connecting pipe 8, and then into the cavity inside the rotating frame 6. The water flow is sprayed out through multiple sets of nozzles 7. The drive motor 15 is started to drive the second synchronous wheel 14 to rotate, and the first synchronous wheel 12 is rotated through the synchronous belt 13, which drives the connecting pipe 8 to rotate, causing the rotating frame 6 to rotate. This causes the multiple sets of nozzles 7 to rotate and shift around the rotating frame 6 as the center, achieving all-round cooling of the submersible pump and increasing the spray cooling effect. Compared with existing submersible pumps, this utility model can improve the overall practicality of the submersible pump through design.

[0039] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
