Description

Technical Field

[0001] This utility model belongs to the technical field of heat dissipation devices, specifically relating to a heat dissipation motor for a submersible signal buoy. Background Technology

[0002] Signal buoys, as important underwater communication and monitoring devices, play a vital role in marine scientific research, underwater exploration, and fisheries operations. However, existing signal buoys face a series of technical challenges in their design and application, limiting their widespread use in underwater navigation and deep-water operations.

[0003] Specifically, the internal space design of existing signal buoys is relatively compact, and their heat dissipation performance is often severely limited due to the need to meet strict waterproof sealing requirements. In an underwater environment, heat dissipation is significantly reduced compared to in air. When critical heat-generating components such as motors operate continuously, if the generated heat cannot be dissipated effectively and promptly, the internal temperature of the buoy will rise rapidly. This rapid temperature increase may not only directly burn out the motor but also cause irreversible damage to other delicate electronic components, thus severely affecting the normal function and lifespan of the signal buoy.

[0004] Therefore, we propose a heat-dissipating motor for submersible signal buoys to solve the above-mentioned technical problems. Utility Model Content

[0005] In order to solve the technical problems existing in the prior art, this utility model proposes a heat dissipation motor for a submersible signal buoy.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A heat dissipation motor for a submersible signal buoy includes a drive motor and a housing fitted outside the drive motor. A rotating shaft is connected to the output shaft of the drive motor. The rotating shaft extends through the housing and is rotatably connected to the housing. A mechanical seal is provided at the rotational position of the rotating shaft and the housing. An air reservoir is detachably connected to the housing. The air reservoir contains heat-conducting oil and communicates with the housing. An air reservoir protective shell is fitted outside the air reservoir. One end of the air reservoir protective shell is detachably connected to the housing, and a sealing ring is provided between the air reservoir protective shell and the housing.

[0008] In a further technical solution, the outer shell includes a front shell and a rear shell, which are detachably and sealed together. The drive motor is mounted inside the rear shell via a motor support plate, and the rotating shaft passes through the front shell and is rotatably connected to it.

[0009] In a further technical solution, the housing also includes a flange, and sealing rings are provided between the front housing and the flange, as well as between the flange and the rear housing. The front housing and the rear housing are connected by the flange.

[0010] In a further technical solution, the rotating shaft passes through the flange and is rotatably connected to the flange, and a skeleton oil seal is provided at the rotation position of the rotating shaft and the flange.

[0011] In a further technical solution, a bearing seat is also included, which is installed inside the housing, and the rotating shaft is rotatably mounted on the bearing seat.

[0012] In a further technical solution, both ends of the bearing seat are provided with angular contact bearings, and the bearing seat is provided with a slip ring inside. The rotating shaft passes through the angular contact bearings and the slip ring in sequence, and is rotatably connected to both the angular contact bearings and the slip ring.

[0013] In a further technical solution, the output shaft and the rotating shaft of the drive motor are connected by a coupling, and both the output shaft and the rotating shaft of the drive motor are provided with flat keys that match the mounting grooves of the coupling.

[0014] In a further technical solution, a fixed bracket is fitted on the outer side of the outer shell for connection with the submersible.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0016] 1. This utility model uses heat-conducting oil as a heat transfer medium, which can absorb and disperse the heat generated by the drive motor during operation, and then dissipate it to the external environment through the casing, thereby achieving efficient cooling of the drive motor, effectively avoiding the risk of overheating and damage to the drive motor, ensuring its stable operation and normal function in extreme environments, and thus extending the service life of the equipment.

[0017] 2. This utility model ensures the airtightness of the entire structure through the design of mechanical seal, airbag protective shell and sealing ring, meets the strict waterproof requirements, effectively prevents seawater infiltration and avoids damage to internal components due to water intrusion.

[0018] 3. This utility model meets the high requirements of deep-sea exploration and underwater operations for the heat dissipation performance and waterproof sealing of the drive motor, providing strong technical support for deep-sea exploration and underwater operations, thus bringing users a more reassuring and convenient user experience.

[0019] 4. This utility model isolates and seals the space between the front and rear shells by using a flange and a skeleton oil seal, ensuring that the heat transfer oil circulates smoothly only in the rear shell. This increases the contact heat exchange opportunity between the heat transfer oil and the drive motor, thereby achieving efficient cooling of the drive motor, improving the heat dissipation efficiency of the drive motor, and ensuring its stable performance and service life under high load operation.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. 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 scope of protection of the present utility model.

[0028] See Figures 1-5This utility model provides a heat dissipation motor for a submersible signal buoy, including a drive motor 1 and a housing sleeved on the outside of the drive motor 1. A rotating shaft 2 is connected to the output shaft of the drive motor 1. The rotating shaft 2 extends through the housing and is rotatably connected to the housing. A mechanical seal 3 is provided at the rotation position of the rotating shaft 2 and the housing. An air storage bladder 4 is detachably connected to the housing. The air storage bladder 4 contains heat-conducting oil and communicates with the housing. An air bladder protective shell 5 is sleeved on the outside of the air storage bladder 4. One end of the air bladder protective shell 5 is detachably connected to the housing, and a sealing ring is provided between the air bladder protective shell 5 and the housing.

[0029] To address the problem of limited heat dissipation due to the compact internal space design and waterproof sealing requirements of existing submersible signal buoys, which severely impacts their normal function and lifespan, this submersible signal buoy utilizes a cooling motor. This motor employs heat-conducting oil as a heat transfer medium, allowing it to flow freely within the outer shell. Through direct contact with the drive motor 1, it absorbs and disperses the heat generated during operation, then transfers it to the outer shell, which ultimately dissipates the heat to the external environment. This process achieves efficient cooling of the drive motor 1, effectively preventing overheating and damage, ensuring stable operation and normal function in extreme environments, and extending the equipment's lifespan. Furthermore, the design of the mechanical seal 3, the airbag protective shell 5, and the sealing ring ensures the overall structural airtightness, meeting stringent waterproof requirements and effectively preventing seawater infiltration and damage to internal components. This design meets the high demands of deep-sea exploration and underwater operations for the heat dissipation and waterproof sealing of the drive motor 1, providing strong technical support for deep-sea exploration and underwater operations, and ultimately offering users a safer and more convenient experience.

[0030] In one specific implementation, see Figure 2 and Figure 4 The outer shell includes a front shell 6 and a rear shell 7, which are detachably and sealed together. The drive motor 1 is installed inside the rear shell 7 via a motor support plate 16. The rotating shaft 2 passes through the front shell 6 and is rotatably connected to the front shell 6.

[0031] The detachable sealed connection between the front housing 6 and the rear housing 7 allows users to easily disassemble the housing and inspect, maintain, or replace key components such as the drive motor 1 and the rotating shaft 2 inside. This not only improves the maintainability of the equipment, making maintenance more efficient and convenient, but also effectively reduces maintenance costs. Through timely maintenance and replacement, the overall service life of the equipment is further extended.

[0032] In one specific implementation, see Figure 2 and Figure 4The outer shell also includes a flange 8. A sealing ring is provided between the front shell 6 and the flange 8, as well as between the flange 8 and the rear shell 7. The front shell 6 and the rear shell 7 are connected by the flange 8.

[0033] The flange 8 and its matching sealing ring connect the front shell 6 and the rear shell 7, ensuring a stable connection and effectively dispersing various external forces experienced by the shell underwater, thus improving overall impact resistance and structural strength. The double-layer seal further enhances sealing performance, effectively preventing moisture from entering the shell and protecting the drive motor 1 and other electronic components from damage, ensuring the equipment's waterproof performance and long-term stable operation.

[0034] In one specific implementation, see Figure 4 The rotating shaft 2 passes through the flange 8 and is rotatably connected to the flange 8. The rotating shaft 2 and the flange 8 are provided with a skeleton oil seal 9 at the rotation position.

[0035] By rotatably mounting the shaft 2 on the flange 8 and using a skeleton oil seal 9 at the rotation position between the shaft 2 and the flange 8, isolation and sealing of the space between the front housing 6 and the rear housing 7 are achieved. This design prevents the heat transfer oil in the rear housing 7 from seeping into the front housing 6, ensuring that the heat transfer oil circulates smoothly only within the rear housing 7. This increases the contact heat exchange opportunity between the heat transfer oil and the drive motor 1, thereby achieving efficient cooling of the drive motor 1, improving the heat dissipation efficiency of the drive motor 1, and ensuring its stable performance and service life under high load operation.

[0036] In one specific implementation, see Figure 5 It also includes a bearing seat 10, which is installed inside the housing, and the rotating shaft 2 is rotatably mounted on the bearing seat 10.

[0037] As a key support structure for the rotating shaft 2, the bearing seat 10 provides stable support for the rotating shaft 2, effectively reducing the shaking and friction of the rotating shaft 2 during rotation, thereby enhancing the stability and smoothness of rotation, ensuring that the equipment can maintain a high degree of stability and reliability during operation, and thus guaranteeing the continuous normal operation of the equipment.

[0038] In one specific implementation, see Figure 5 Both ends of the bearing seat 10 are provided with angular contact bearings 11, and the inside of the bearing seat 10 is provided with a slip ring 12. The rotating shaft 2 passes through the angular contact bearing 11 and the slip ring 12 in sequence, and is rotatably connected to both the angular contact bearing 11 and the slip ring 12.

[0039] By setting angular contact bearing 11 and slip ring 12 on the bearing seat 10, the stability of the rotating shaft 2 during rotation is ensured. It can also effectively distribute the radial and axial loads on the rotating shaft 2, reduce wear and vibration, and enable the rotating shaft 2 to maintain good rotation performance after long-term operation. This not only extends the service life of the rotating shaft 2, but also greatly improves the overall operating efficiency and reliability of the equipment, bringing many conveniences and advantages to users.

[0040] In one specific implementation, see Figure 4 and Figure 5 The output shaft of the drive motor 1 and the rotating shaft 2 are connected by a coupling 13. Both the output shaft of the drive motor 1 and the rotating shaft 2 are provided with flat keys 14 that match the mounting grooves of the coupling 13.

[0041] Coupling 13 serves as the connecting bridge between the output shaft of drive motor 1 and rotating shaft 2. Through the tight fit of key 14, it ensures the coaxiality and rotational stability between the two. This design can effectively transmit the torque of drive motor 1, reduce energy loss during transmission, and improve overall transmission efficiency.

[0042] In one specific implementation, see Figure 1 and Figure 2 The outer side of the outer shell is fitted with a fixed bracket 15 for connecting to the submersible.

[0043] A stable and reliable connection is achieved between the fixed bracket 15 and the submersible. The fixed bracket 15 acts as a connecting bridge, ensuring a tight fit between the outer shell and the submersible, and providing necessary support and stability. Simultaneously, the fixed bracket 15 improves the ease of installation and disassembly; the outer shell can be quickly and easily assembled or separated from the submersible. This reduces operational difficulty and time costs, and improves operational efficiency, enabling the submersible to deploy and recover the outer shell and its internal motors more flexibly and quickly during missions.

[0044] It is worth mentioning that the above-mentioned detachable connection adopts a threaded connection or other conventional technical means in the prior art, which can be fully implemented by those skilled in the art, and will not be elaborated here.

[0045] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
