Description

Technical Field

[0001] This utility model relates to the field of underwater motor sealing technology, specifically an underwater motor sealing chamber. Background Technology

[0002] With the deepening of marine resource development and underwater operations, such as deep-sea exploration, seabed sampling, and underwater construction, the application of underwater equipment is becoming more and more widespread. As the core power component of underwater robots, submersibles, and other equipment, the demand for underwater motors is also increasing. These operating environments are often accompanied by problems such as high pressure and water corrosion, which places extremely high demands on the sealing performance of motors to ensure stable and reliable operation, thereby ensuring the smooth progress of underwater operations.

[0003] A search revealed prior art publication number CN214154218U, which discloses an underwater dual-output shaft motor sealing chamber, including a chamber body, a first cover, a second cover, and a watertight connector. The chamber body is a cylindrical component, and both the first and second covers are cylindrical covers that match the chamber body, respectively, and are sealed and fixed to both ends of the chamber body. The first cover has a coaxial first shaft hole, the inner end of which is fitted with a first bearing. The second cover has an assembly hole in the middle, and a bearing seat is installed in the assembly hole. A movable gap is formed between the bearing seat and the inner wall of the assembly hole. The outer end of the bearing seat has a sealing flange that seals against the outer end of the second cover. The bearing seat has a second shaft hole, the inner end of which is fitted with a second bearing. The watertight connector is sealed and connected to the cable interface at the outer end of the first cover. Advantages: compact structure, light weight; good synchronization after dual-output shaft assembly; good overall underwater sealing performance.

[0004] However, current technology cannot effectively clean the deposits on the outer surface of the cabin. The underwater environment is complex, rich in salt, microorganisms, and other impurities. After prolonged underwater operations, algae, shellfish, silt, and other debris easily adhere to the surface of the sealed cabin. On the one hand, these deposits increase water flow resistance, reducing the overall maneuverability and operational efficiency of the equipment; on the other hand, if the deposits contain corrosive substances, they will accelerate the corrosion of the sealed cabin.

[0005] Therefore, based on the above-mentioned search and combined with existing technologies, an underwater motor sealing chamber is proposed to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide an underwater motor sealing chamber to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An underwater motor sealing chamber includes: a sealing chamber body, on which a cleaning mechanism is provided, the cleaning mechanism including: a first fixing block, the first fixing block being fixedly installed on the left side of the top surface of the sealing chamber body, a second fixing block being fixedly installed on the right side of the top surface of the sealing chamber body, a reciprocating screw being rotatably connected between the first fixing block and the second fixing block, a collar being sleeved on the outer surface of the sealing chamber body, a scraper being fixedly installed on the inner wall of the collar, the scraper contacting the surface of the sealing chamber body, and the cleaning mechanism also including a drive assembly.

[0009] Furthermore, the drive assembly includes: an underwater motor body, which is fixedly installed inside the sealed chamber body, the output shaft of the underwater motor body extends through the side wall of the sealed chamber body to the outside of the sealed chamber body, and a coupling is fixedly installed on the outer surface of the underwater motor body.

[0010] Furthermore, the drive assembly also includes a rotating column, which is rotatably mounted on the right side wall of the fixed block two. The left side wall of the rotating column is connected to the right side wall of the reciprocating lead screw. A coupling two is fixedly mounted on the right side wall of the rotating column. A synchronous belt is provided between the coupling one and the coupling two. The drive assembly also includes a connecting component.

[0011] Furthermore, the connecting component includes: a connecting block disposed on the outer surface of the reciprocating lead screw, the connecting block being threadedly connected to the reciprocating lead screw, a connecting groove being formed on the top surface of the collar, and the bottom surface of the connecting block being fixedly connected to the top surface of the connecting groove.

[0012] Furthermore, an L-shaped protective chamber is fixedly installed on the right side wall of the sealed chamber body. The first coupling, the rotating column, the second coupling, the synchronous belt and the second fixing block are located in the L-shaped protective chamber, and the output shaft of the underwater motor body passes through the side wall of the L-shaped protective chamber.

[0013] Furthermore, a sealing ring is fixedly installed at the junction of the L-shaped protective chamber and the reciprocating lead screw.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In this utility model, a cleaning mechanism is provided, in which fixed block one, fixed block two, reciprocating screw, collar, scraper, and drive assembly cooperate to achieve automatic cleaning of deposits on the outer surface of the sealed chamber. After the underwater motor body is started, the reciprocating screw is driven to rotate via coupling one, synchronous belt, and coupling two, which in turn causes the connecting block to reciprocate linearly along the reciprocating screw, driving the collar and scraper to move along the surface of the sealed chamber body to scrape off the deposits. This effectively solves the problem of difficult cleaning of deposits on the surface of the sealed chamber in the prior art, reduces water flow resistance, reduces corrosion risk, significantly improves the stability and reliability of the sealed chamber in complex underwater environments, and ensures the normal operation and safety of the underwater motor.

[0016] 2. In this utility model, the L-shaped protective chamber and sealing ring achieve efficient protection of the drive components. The L-shaped protective chamber houses key components such as coupling one, rotating column, coupling two, and timing belt, preventing water interference and ensuring stable operation of the drive components. Simultaneously, the sealing ring further enhances the sealing performance, preventing water from seeping into the chamber from the junction of the L-shaped protective chamber and the reciprocating screw. These protective measures effectively solve the problem of drive component failure or damage caused by water intrusion in existing technologies, extending the service life of the equipment.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] In one typical implementation of this application, please refer to Figures 1-5 As shown, an underwater motor sealing chamber includes: a sealing chamber body 1, the outer surface of which is coated with a hydrophobic coating containing nano-silica, and a cleaning mechanism is provided on the sealing chamber body 1, the cleaning mechanism including:

[0025] Fixed block 2 is fixedly installed on the left side of the top surface of the sealed chamber body 1. Fixed block 3 is fixedly installed on the right side of the top surface of the sealed chamber body 1. A reciprocating screw 4 is rotatably connected between fixed block 2 and fixed block 3. The reciprocating screw 4 is made of titanium alloy TC4 (tensile strength ≥900MPa, seawater corrosion resistant). A collar 5 is sleeved on the outer surface of the sealed chamber body 1. A scraper 6 is fixedly installed on the inner wall of the collar 5. The scraper 6 is made of tungsten carbide hard alloy (hardness ≥HRA92, bending strength ≥3000MPa). The scraper 6 is in contact with the surface of the sealed chamber body 1. The cleaning mechanism also includes a drive assembly.

[0026] Through the above features, the outer surface of the sealed chamber body 1 can be cleaned. Specifically, the drive assembly drives the collar 5 to move back and forth on the outer surface of the sealed chamber body 1. When the collar 5 moves, the scraper 6 on the collar 5 cleans the attached substances on the outer surface of the sealed chamber body 1.

[0027] As a preferred embodiment of this example, please refer to [link / reference]. Figure 3 As shown, the drive assembly includes: an underwater motor body 9, which is fixedly installed inside the sealed chamber body 1. The output shaft of the underwater motor body 9 extends through the side wall of the sealed chamber body 1 to the outside of the sealed chamber body 1. A coupling 10 is fixedly installed on the outer surface of the underwater motor body 9. The drive assembly also includes: a rotating column 11, which is rotatably installed on the right side wall of the fixed block 3. The left side wall of the rotating column 11 is connected to the right side wall of the reciprocating screw 4. A coupling 12 is fixedly installed on the right side wall of the rotating column 11. A synchronous belt 13 is provided between the coupling 10 and the coupling 12. The drive assembly also includes connecting parts.

[0028] Based on the above features, when the output shaft of the underwater motor body 9 rotates, the coupling 10 on the underwater motor body 9 will rotate synchronously. When the coupling 10 rotates, the rotating column 11 on the fixed block 3 will rotate synchronously with the synchronous belt 13 through the coupling 12. When the rotating column 11 rotates, the reciprocating screw 4 will rotate synchronously.

[0029] As a preferred embodiment of this example, please refer to [link / reference]. Figure 4 As shown, the connecting component includes: a connecting block 8, which is disposed on the outer surface of the reciprocating lead screw 4 and is threadedly connected to the reciprocating lead screw 4; a connecting groove 7 is provided on the top surface of the collar 5; and the bottom surface of the connecting block 8 is fixedly connected to the top surface of the connecting groove 7.

[0030] It is worth mentioning that an optical fiber biofilm thickness sensor (10μm resolution) can be embedded on the surface of the sealed chamber body 1. When the thickness of the attached biofilm is detected to be greater than 100μm, the cleaning mechanism is automatically activated, and the rotation speed of the underwater motor body 9 can be dynamically adjusted according to the density of the attached biofilm.

[0031] Based on the above features, when the reciprocating screw 4 rotates, the connecting block 8 will move back and forth on the outer surface of the reciprocating screw 4. When the connecting block 8 moves, it will drive the collar 5 and the scraper 6 to move synchronously.

[0032] As a preferred embodiment of this example, please refer to [link / reference]. Figure 2 and Figure 5 As shown, an L-shaped protective chamber 14 is fixedly installed on the right side wall of the sealed chamber body 1. Coupling 10, rotating column 11, coupling 2 12, synchronous belt 13, and fixing block 2 3 are located within the L-shaped protective chamber 14. The output shaft of the underwater motor body 9 passes through the side wall of the L-shaped protective chamber 14. By providing the L-shaped protective chamber 14, the coupling 10, rotating column 11, coupling 2 12, and synchronous belt 13 are protected from water damage during operation.

[0033] As a preferred embodiment of this example, please refer to [link / reference]. Figure 1 As shown, a sealing ring 15 is fixedly installed at the junction of the L-shaped protective chamber 14 and the reciprocating screw 4. By setting the sealing ring 15, water is prevented from entering the interior of the L-shaped protective chamber 14 through the junction of the L-shaped protective chamber 14 and the reciprocating screw 4.

[0034] Working principle:

[0035] In operation, the underwater motor body 9, fixedly installed inside the sealed chamber body 1, is first started. The output shaft of the underwater motor body 9 begins to rotate, driving the coupling 10, fixed on its outer surface, to rotate synchronously. The coupling 10 is connected to the coupling 12 via a timing belt 13. The coupling 12 is fixedly installed on the right side wall of the rotating column 11. The left side wall of the rotating column 11 is connected to the right side wall of the reciprocating screw 4. Therefore, when the coupling 10 rotates, the rotating column 11 rotates accordingly, thereby driving the reciprocating screw 4 to rotate. A connecting block 8 is provided on the outer surface of the reciprocating screw 4, and the connecting block 8 is threadedly connected to the reciprocating screw 4. A connecting groove 7 is opened on the top surface of the collar 5, and the bottom surface of the connecting block 8 is fixedly connected to the top surface of the connecting groove 7. When the reciprocating screw 4 rotates, the connecting block 8 makes linear reciprocating motion on the outer surface of the reciprocating screw 4, thereby driving the collar 5 to move back and forth along the outer surface of the sealed chamber body 1. A scraper 6 is fixedly installed on the inner wall of the collar 5, and the scraper 6 is in close contact with the surface of the sealing chamber body 1. As the collar 5 moves, the scraper 6 scrapes and cleans the deposits on the outer surface of the sealing chamber body 1. An L-shaped protective chamber 14 is fixedly installed on the right side wall of the sealing chamber body 1. The coupling 10, rotating column 11, coupling 2 12, timing belt 13, and fixing block 2 3 are all located inside the L-shaped protective chamber 14. This prevents water from affecting these components and ensures the normal operation of the drive assembly. At the same time, a sealing ring 15 is fixedly installed at the junction of the L-shaped protective chamber 14 and the reciprocating screw 4, effectively preventing water from seeping into the interior of the L-shaped protective chamber 14 from this junction, further enhancing the sealing and reliability of the entire device. Through the coordinated work of the above components, the automatic cleaning function of the outer surface of the sealing chamber body 1 is realized, ensuring the cleanliness and efficient operation of the sealing chamber in the underwater environment.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
