Description

Technical Field

[0001] This utility model relates to the field of submersible motor cooling technology, and specifically to a self-circulating cooling submersible motor bracket. Background Technology

[0002] Submersible motors are electric motors specifically designed for underwater operation, providing power to underwater machinery. Because submersible motors operate underwater for extended periods, their internal bearings and key components generate significant heat, making air cooling unsuitable for normal motors. Therefore, they require circulating water cooling. Current cooling methods involve connecting a welded water pipe to the motor bracket. When the water pump starts, the impeller rotates, and the pump's suction draws water in. Some of this water flows through the welded water pipe at the motor bracket into the motor's water jacket, cooling the motor. However, due to the high underwater pressure, prolonged operation of the welded water pipe can cause cracking, damage, and deformation at the weld joints. Furthermore, the water jacket itself is a welded component with openings, which can affect its structure. Consequently, excessive underwater pressure can lead to deformation later on, requiring frequent maintenance. Utility Model Content

[0003] The purpose of this invention is to solve the problem that the use of welded water pipes when connecting submersible motors to water pumps can easily lead to malfunctions in the welded water pipes and water jackets, thus posing a safety hazard to the submersible motor. This invention provides a circulating cooling submersible motor bracket that allows water from the water pump to circulate directly with the water jacket through the submersible motor bracket, avoiding the need for holes in the water jacket that could cause abnormalities and thus safety hazards to the submersible motor.

[0004] To achieve the above objectives, this utility model provides a self-circulating cooling submersible motor bracket, comprising a bracket body, which is a hollow tubular structure. The bracket body is arranged from top to bottom along the axis as a motor section and a water pump section. The bracket body is provided with an inlet pipe groove and an outlet pipe groove, which penetrate the motor section and the water pump section. One end of the inlet pipe groove is connected to the water pump outlet, and the other end is connected to the motor water jacket inlet. One end of the outlet pipe groove is connected to the motor water jacket outlet, and the other end is connected to the water pump return port, so as to realize the self-circulation of the motor cooling water flow.

[0005] Preferably, the top ring shaft of the motor section is provided with a plurality of mounting holes at intervals for inserting fixing components.

[0006] Preferably, the pump section is provided with a slot for connecting to the pump outlet.

[0007] Preferably, the outer diameter of the pump section gradually decreases in the direction away from the motor section to fit the frustum-shaped structure of the pump inlet.

[0008] Preferably, one end of the water inlet pipe is located at the top of the motor section and the other end is located at the bottom of the water pump section, and the inner diameter of the water inlet pipe remains consistent from the water pump section to the motor section.

[0009] Preferably, one end of the water outlet pipe groove is located at the top of the motor section, and the other end is located on the side of the slot. The opening height of the water outlet pipe groove on the side of the slot is lower than the docking height between the water inlet pipe groove and the water pump.

[0010] Preferably, the upper outer side of the pump section extends downward along the motor section to form an extension surface parallel to the horizontal plane.

[0011] The above technical solution allows for the circulation of cooling water between the water jacket and the water pump through the inlet and outlet pipes on the main body of the bracket. The bracket can be directly installed between the submersible motor and the water pump, which simplifies the installation process and reduces production costs. The submersible motor is connected to the motor section and the water pump is connected to the water pump section, thus achieving the integration of the submersible motor and the water pump. This effectively avoids the safety hazards caused by drilling holes in the motor water jacket, which could lead to abnormalities in the motor water jacket and consequently, safety hazards in the submersible motor.

[0017] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0018] As mentioned above, this utility model provides a self-circulating cooling submersible motor bracket, including a bracket body 1. The bracket body 1 is a hollow tubular structure. The bracket body 1 is arranged from top to bottom along the axis as a motor section 2 and a water pump section 3. The bracket body 1 is provided with a water inlet pipe groove 4 and a water outlet pipe groove 5. The water inlet pipe groove 4 and the water outlet pipe groove 5 pass through the motor section 2 and the water pump section 3. The cooling water of the water jacket 8 and the water pump 7 is circulated through the water inlet pipe groove 4 and the water outlet pipe groove 5 provided on the bracket body 1. This bracket can be directly assembled between the submersible motor 6 and the water pump 7 for use. It simplifies the installation process and reduces production costs. The submersible motor 6 is connected to the motor section 2 and the water pump 7 is connected to the water pump section 3 to achieve integration of the submersible motor 6 and the water pump 7. It effectively avoids the abnormality of the motor water jacket 8 caused by drilling holes in the motor water jacket 8, which in turn leads to safety hazards for the submersible motor 6. In addition, compared with welding water pipes to the motor water jacket, the submersible motor and water pump connected by this submersible motor bracket have a more regular shape and are easier to place.

[0019] In some embodiments, the top ring shaft of the motor section 2 is provided with a plurality of mounting holes 21 at intervals for mounting the fixing components. The submersible motor 6 can be directly fixed to the bracket through the mounting holes 21, which improves the accuracy of the installation and avoids the cooling effect of the motor water jacket 8 being reduced or even damaged by the submersible motor 6 itself due to misalignment of the inlet and outlet. It should be noted that the present invention does not make any special limitation on the specific form of the fixing components. Its main function is to fix the bracket body 1 and the submersible motor 6. For example, it can be set as a combination structure of screw and nut.

[0020] According to the technical solution provided by this utility model, the water pump section 3 is provided with a slot 31 for connecting with the water outlet end of the water pump 7. The outer diameter of the water pump section 3 gradually decreases in the direction away from the motor section 2 to adapt to the frustum-shaped structure of the water inlet end of the water pump 7. This design is to adapt the bracket to the conical structure of the water inlet end of the water pump 7, while reducing the flow resistance of water in the water pump section 3.

[0021] In this utility model, one end of the water inlet pipe groove 4 is located at the top of the motor section 2, and the other end is located at the bottom of the water pump section 3. The inner diameter of the water inlet pipe groove 4 is consistent from the water pump section 3 to the motor section 2 to ensure stable water flow. One end of the water outlet pipe groove 5 is located at the top of the motor section 2, and the other end is located on the side of the slot 31. The opening height of the water outlet pipe groove 5 on the side of the slot 31 is lower than the docking height between the water inlet pipe groove 4 and the water pump 7 to prevent backflow of cooling water during circulation.

[0022] In some embodiments, the upper outer side of the pump section 3 extends downward along the motor section 2 to form an extension surface parallel to the horizontal plane. This design is intended to allow the extension surface to support the upper surface of the pump 7 and to form a water flow guide step, thereby reducing the impact of water flow on the connection between the pump section 3 and the motor section 2.

[0023] like Figure 3 As shown, in a specific embodiment, the self-circulating cooling submersible motor 6 bracket is disposed between the submersible motor 6 and the water pump 7. One end of the water inlet pipe groove 4 is disposed at the top of the motor section 2, and the other end is disposed at the bottom of the water pump section 3. One end of the water outlet pipe groove 5 is disposed at the top of the motor section 2, and the other end is disposed on the side of the slot 31. The upper end is connected to the submersible motor 6 through multiple mounting holes 21. A bearing is held in the slot 31. A bearing cover is also disposed between the submersible motor 6 bracket and the submersible motor 6. Similarly, holes are provided on the bearing cover above the corresponding water inlet pipe groove 4 and water outlet pipe groove 5 on the submersible motor 6 bracket to allow cooling water to flow. The upper outer side of the water pump section 3 extends downward along the motor section 2, and the bottom surface of the extension is parallel to the horizontal plane. This design makes the bracket stable when connected to the water pump 7. It should be noted that in this embodiment, the submersible motor 6 bracket is reinforced and connected to the submersible motor 6 and the water pump 7 by a spiral locking structure.

[0024] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings; however, the present invention is not limited thereto. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention. To avoid unnecessary repetition, the present invention will not describe the various possible combinations separately. However, these simple modifications and combinations should also be considered as the content disclosed in the present invention and are all within the protection scope of the present invention.
