Description

Technical Field

[0001] This utility model relates to a submersible fin adjustment device, specifically a submersible propulsion fin adjustment device, belonging to the field of submersible technology. Background Technology

[0002] A submersible, also known as a deep-sea submersible or submersible vehicle, is a deep-sea diving device equipped with detection equipment and a robotic arm to perform underwater operations. It is primarily used for seabed exploration, biological surveys, shipwreck salvage, and rescue missions, and can also serve as an underwater operational base for divers. Its non-pressure-resistant outer shell houses a battery, environmental control system, and sonar equipment. The outer shell is equipped with thrusters for multi-directional movement, and the robotic arm can collect samples.

[0003] Patent application CN214190053U relates to a thruster and a submersible. The thruster includes a housing and a fairing, the housing being connected to the fairing. It also includes a directional rudder, which comprises: a servo motor connected to the fairing and located at the water outlet end of the fairing; and a rudder blade connected to the output shaft of the servo motor, extending from the servo motor towards the axis of the fairing. The thruster of this application achieves vector propulsion and torque control through the directional rudder, improving the thruster's control performance.

[0004] When using a submersible, fins are used to adjust the angle of water propulsion in order to control the submersible's direction of travel, thereby controlling the submersible's up-and-down or left-and-right movement. Although the propulsion device in the aforementioned patent improves the control effect, multiple fins with different angles need to be installed to facilitate angle control, which increases the difficulty of fin control and affects the ease of use of the submersible. Utility Model Content

[0005] (a) Technical problems to be solved The purpose of this invention is to provide a submersible propulsion fin adjustment device to solve the above-mentioned problems, thereby addressing the issue in the prior art where multiple angle fin adjustments are required for vertical or horizontal movement.

[0006] (II) Technical Solution This utility model is achieved through the following technical solution: a submersible propulsion fin adjustment device.

[0007] The device includes a thruster, the tail end of which is rotatably connected to an adjustment tube. Inside the adjustment tube, there are equidistantly arranged adjustment fins. At the top of the adjustment tube, there is an adjustment mechanism. The adjustment mechanism includes a bevel gear, an adjustment gear, and a linkage clamp. The adjustment gear is rotatably connected to the adjustment tube. A fixed toothed ring is fixedly connected to the surface of the thruster, and the teeth of the adjustment gear mesh with those of the fixed toothed ring.

[0008] Preferably, a linkage rod is provided above the regulating tube, and a connecting crossbar is fixedly connected to one end of the regulating fin. Each connecting crossbar is rotatably connected to the linkage rod. The first bevel gear is fixedly connected to the adjacent regulating fin. Through the linkage rod and the connecting crossbar, several regulating fins are linked together. When the first bevel gear controls the rotation of one regulating fin, it can drive the other regulating fins to rotate synchronously.

[0009] Preferably, the adjusting mechanism is provided with a sealing cover, and the bottom end of the sealing cover is fixedly connected to the adjusting pipe. One end of the adjusting gear passes through the sealing cover and is rotatably connected to the sealing cover. The sealing cover seals and protects the adjusting mechanism, preventing leakage from damaging the adjusting mechanism and improving the stability of the adjusting mechanism's operation.

[0010] Preferably, the first bevel gear is meshed with a second bevel gear, and the second bevel gear is rotatably connected to the adjusting tube. The other end of the second bevel gear is fixedly connected to a first linkage sleeve. By rotating the first linkage sleeve, the second bevel gear is controlled to rotate synchronously, and the first bevel gear is driven to rotate synchronously through meshing transmission.

[0011] Preferably, one end of the adjusting gear is fixedly connected to a second linkage sleeve. The first linkage sleeve, the second linkage sleeve, and the linkage clamp are located on the same axis, and the first linkage sleeve and the second linkage sleeve are both adapted to the linkage clamp. By moving the linkage clamp laterally, the linkage clamp is controlled to engage with the first linkage sleeve or the second linkage sleeve. By rotating the linkage clamp, the linkage sleeve engaged with it rotates synchronously.

[0012] Preferably, a linkage gear is fixedly connected to the middle of the linkage clamp head, and an adjustment frame is rotatably connected to the middle of the linkage clamp head. The bottom of the adjustment frame is slidably connected to the surface of the adjustment tube. The linkage clamp head is positioned by the adjustment frame to improve the stability of the linkage clamp head operation.

[0013] Preferably, an electric push rod is fixedly connected to the surface of the regulating tube, and the output end of the electric push rod... It is fixedly connected to the adjustment frame, and the adjustment frame is controlled to move laterally by an electric push rod, which in turn causes the adjustment frame to drive the linkage clamp head to move laterally.

[0014] Preferably, a power gear is rotatably connected to the surface of the regulating tube, and the linkage gear is meshed with the power gear. A waterproof motor for controlling the rotation of the power gear is fixedly connected to the surface of the regulating tube. The power gear is rotated by controlling the rotation of the power gear through the waterproof motor, so that the power gear drives the linkage gear to rotate synchronously.

[0015] This utility model provides a submersible propulsion fin adjustment device, which has the following beneficial effects: 1. The submersible's propulsion fin adjustment device controls the rotation of the adjustment fins or the adjustment tube by moving the linkage clamp laterally. The rotation of the bevel gear controls the rotation of the adjustment fins, adjusting the direction of water flow. The rotation of the adjustment gear on the surface of the fixed gear ring controls the rotation of the adjustment tube at the tail end of the propeller, thereby rotating the adjustment fins to a suitable horizontal angle. The rotation of the adjustment tube at the tail end of the propeller rotates the adjustment fins to a suitable horizontal angle. By rotating the adjustment fins, the direction of water flow is changed, controlling the submersible's up, down, left, and right movement. This reduces the difficulty of adjusting the submersible's angle, simplifies the cumbersome procedures of submersible operation, and improves the ease of use of the submersible.

[0016] 2. The submersible's propulsion fin adjustment device links several adjustment fins together via a linkage rod and a connecting crossbar. When bevel gear one controls the rotation of one adjustment fin, it can drive the remaining adjustment fins to rotate synchronously. By rotating linkage sleeve one, bevel gear two is controlled to rotate synchronously. Through meshing transmission, bevel gear one is driven to rotate synchronously. By moving the linkage clamp laterally, the linkage clamp is controlled to engage with linkage sleeve one or linkage sleeve two. By rotating the linkage clamp, the linkage sleeve engaged with it rotates synchronously. The adjustment frame positions the linkage clamp, improving the stability of the linkage clamp's operation.

[0017] 3. The submersible's propulsion fin adjustment device controls the synchronous rotation of the linkage clamp head via a linkage gear, and controls the lateral movement of the adjustment frame via an electric push rod. This, in turn, causes the adjustment frame to move the linkage clamp head laterally. A waterproof motor controls the rotation of the power gear, which in turn drives the linkage gear to rotate synchronously. A sealing cover seals and protects the adjustment mechanism, preventing leakage and damage to the equipment. The high stability of the regulating mechanism and the direct contact between the sealing cover and the external water body can cool the electric push rod and waterproof motor inside the sealing cover.

[0020] This utility model provides a submersible propulsion fin adjustment device.

[0021] Example 1: Please see Figure 1 and Figure 2 The device includes a thruster 1, which is the power unit of the submersible. This application can use the propulsion device used in the patent (CN117508527A An Underwater Sightseeing Submersible). The tail end of the thruster 1 is rotatably connected to an adjustment pipe 2. The inside of the adjustment pipe 2 is rotatably connected to an equidistantly arranged adjustment fin 3. By rotating the adjustment pipe 2 at the tail end of the thruster 1, the adjustment fin 3 is rotated to a suitable horizontal angle. By rotating the adjustment fin 3, the direction of water flow is changed, and the submersible is controlled to move up, down, left, and right. This reduces the difficulty of adjusting the angle of the submersible, reduces the cumbersome procedures of submersible operation, and improves the convenience of using the submersible.

[0022] A connecting rod 5 is installed above the regulating tube 2, and a connecting crossbar is fixedly connected to one end of the regulating fin 3. 4. Each connecting crossbar 4 is rotatably connected to the linkage rod 5, and the bevel gear 701 is connected to the adjacent adjusting fin. The plate 3 is fixedly connected, and through the linkage rod 5 and the connecting crossbar 4, several adjusting fins 3 are linked together. When the bevel gear 701 controls the rotation of one adjusting fin 3, it can drive the other adjusting fins 3 to rotate synchronously.

[0023] The top end of the regulating pipe 2 is provided with an regulating mechanism 7, which includes a bevel gear 701, an regulating gear 704 and a linkage clamp 708. By moving the linkage clamp 708 laterally, the power source is controlled to rotate the regulating fin 3 or the regulating pipe 2. By rotating the bevel gear 701, the regulating fin 3 is controlled to rotate, thereby adjusting the direction of water flow.

[0024] Example 2: Please refer to it again. Figure 2 , Figure 3 and Figure 4 The first bevel gear 701 is meshed with the second bevel gear 702, and the second bevel gear 702 is rotatably connected to the adjusting tube 2. The other end of the second bevel gear 702 is fixedly connected to the first linkage sleeve 703. By rotating the first linkage sleeve 703, the second bevel gear 702 is controlled to rotate synchronously, and the first bevel gear 701 is driven to rotate synchronously through meshing transmission.

[0025] The adjusting gear 704 is rotatably connected to the adjusting tube 2. A fixed toothed ring 705 is fixedly connected to the surface of the pusher 1, and the teeth of the adjusting gear 704 and the fixed toothed ring 705 are meshed. The opening angle of the teeth on the surface of the fixed toothed ring 705 is greater than 110°, which can meet the adjustment requirements of the adjusting fin 3 from a vertical state to a horizontal state. By rotating the adjusting gear 704 on the surface of the fixed toothed ring 705, the adjusting tube 2 is controlled to rotate at the tail end of the pusher 1, thereby rotating the adjusting fin 3 to a suitable horizontal angle.

[0026] One end of the adjusting gear 704 is fixedly connected to a second linkage sleeve 706. The first linkage sleeve 703, the second linkage sleeve 706, and the linkage clamp 708 are located on the same axis, and both the first linkage sleeve 703 and the second linkage sleeve 706 are adapted to the linkage clamp 708. By moving the linkage clamp 708 laterally, the linkage clamp 708 is controlled to engage with the first linkage sleeve 703 or the second linkage sleeve 706. By rotating the linkage clamp 708, the linkage sleeve engaged with it is driven to rotate synchronously.

[0027] A linkage gear 707 is fixedly connected to the middle of the linkage clamp 708, and an adjusting frame 709 is rotatably connected to the middle of the linkage clamp 708. The bottom of the adjusting frame 709 is slidably connected to the surface of the adjusting tube 2. The adjusting frame 709 is used to position the linkage clamp 708, improving the stability of the linkage clamp 708's operation. The linkage gear 707 controls the synchronous rotation of the linkage chuck 708.

[0028] Example 3: Please refer to it again. Figure 2 and Figure 4 An electric push rod 710 is fixedly connected to the surface of the regulating tube 2, and the output end of the electric push rod 710 is fixedly connected to the regulating frame 709. The electric push rod 710 is a mature device. This application can use any existing device that can control the movement of the regulating frame 709. The electric push rod 710 controls the lateral movement of the regulating frame 709, thereby causing the regulating frame 709 to drive the linkage clamp head 708 to move laterally.

[0029] The surface of the regulating tube 2 is rotatably connected to the drive gear 711, and the linkage gear 707 is connected to the drive gear. The 711 meshing connection is provided. A waterproof motor 712 that controls the rotation of the power gear 711 is fixedly connected to the surface of the regulating tube 2. The waterproof motor 712 is a mature device. This application can use any existing device that can control the rotation of the power gear 711. The power gear 711 is controlled to rotate by the waterproof motor 712, so that the power gear 711 drives the linkage gear 707 to rotate synchronously.

[0030] The regulating mechanism 7 is equipped with a sealing cover 6, and the bottom end of the sealing cover 6 is fixedly connected to the regulating pipe 2. One end of the regulating gear 704 passes through the sealing cover 6 and is rotatably connected to the sealing cover 6. The sealing cover 6 seals and protects the regulating mechanism 7, preventing leakage from damaging the regulating mechanism 7 and improving the stability of the regulating mechanism 7. The sealing cover 6 is in direct contact with the external water body, which can cool the electric push rod 710 and waterproof motor 712 inside the sealing cover 6. An inspection hole is provided on one side of the sealing cover 6, which can periodically add lubricating oil to the inside of the sealing cover 6 to lubricate the transmission equipment and improve the service life of the equipment.

[0031] In use, when it is necessary to control the submersible to move downwards, the adjusting frame 709 is first moved laterally by the electric push rod 710, so that the linkage clamp 708 engages with the linkage sleeve 706. The waterproof motor 712 controls the power gear 711 to rotate, so that the linkage gear 707 controls the linkage clamp 708 to rotate, so that the linkage sleeve 706 drives the adjusting gear 704 to rotate on the surface of the fixed gear ring 705, controlling the adjusting tube 2 to rotate at the tail end of the thruster 1, rotating the adjusting fin 3 to the horizontal direction. Then, the adjusting frame 709 is moved laterally by the electric push rod 710, so that the linkage clamp 708 engages with the linkage sleeve 703. The linkage clamp 708 controls the linkage sleeve 703, so that the bevel gear 702 drives the bevel gear 701 to rotate. The mechanism, through the linkage of the connecting rod 5 and the connecting crossbar 4, controls the synchronous rotation of the adjusting fin 3, causing the tail end of the adjusting fin 3 to flip downwards. When the liquid flowing out of the thruster 1 flows out through the adjusting fin 3, it will generate an upward thrust on the tail end of the submersible, causing the front end of the submersible to point downwards and the tail end to point upwards. After the submersible angle is adjusted, the waterproof motor 712 is controlled to rotate in the opposite direction, adjusting the adjusting fin 3 to a parallel state with the submersible, thus controlling the submersible to move downwards. Through the above device, it is not necessary to control multiple fins to operate simultaneously, reducing the number of fins used and operated, which reduces the weight of submersible parts, reduces the difficulty of submersible operation, and improves the convenience of submersible use.
