Specific implementation method

[0024] The following describes the principles and features of the present invention in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0025] If Figure 1 As shown in the figure, a prone underwater navigation search and operation auxiliary device comprises a main frame mechanism 1, a prone board 2 arranged on the main frame mechanism 1, a steering mechanism 3 arranged in front of the prone board 2 and capable of sliding along the main frame mechanism 1, a mounting frame 4 arranged behind the prone board 2, and a propulsion mechanism 5 movably connected to the mounting frame 4. The main frame mechanism 1 is a frame structure as a whole, which helps to reduce the overall weight. According to actual use needs, it can be selected whether to set a fixed floating frame 6 and a buoy 7 on the main frame mechanism 1. The buoyancy of the fixed floating frame 6 and the buoy 7 is much greater than the overall weight of the device. When the fixed floating frame 6 and the buoy 7 are installed, the buoy 7 always floats on the water surface, and the other parts sink under the water, so that the entire device is fixed at a certain depth below the water surface without sinking. This makes it convenient for personnel to explore and operate at a fixed depth underwater; in particular, it avoids the danger of personnel sinking. When the fixed floating frame 6 and the buoy 7 are not installed, the entire device is no longer subject to positioning control, so personnel can freely dive, explore and operate underwater by manipulating the device. The propulsion device can slide on the mounting frame 4 on the main frame mechanism 1 through the slide buckle to adjust the distance from the prone reclining board 2, and the propulsion device and the mounting frame 4 are fixed by bolts and / or screws, so as to adjust the distance between the pedal 51 of the propulsion device and the prone reclining board 2, so as to be suitable for people of different heights. ​​​

[0026] Through the setting of the steering mechanism 3, left and right steering and up and down lifting operations are realized, and the operation is flexible. For example Figure 2 As shown, the steering mechanism 3 includes a bogie 30, left and right steering rudders 32 axially arranged on the bogie 30 through a rotating shaft 31, and an up and down steering rudder 33 penetrating through the end of the rotating shaft 31 and rotatable around the through hole of the rotating shaft 31. The bogie 30 is slidably arranged on the main frame mechanism 1. A sliding sleeve is arranged on the bogie 30, and the bogie 30 slides along the main frame mechanism 1 through the sliding sleeve. The up and down steering rudder 33 includes a direction rod 330 and steering vanes 331 respectively arranged at both ends of the direction rod 330. A through hole is opened on the rotating shaft 31, and the direction rod 330 penetrates through the through hole and can rotate around the through hole. When traveling, when the direction rod 330 is rotated, the rotating shaft 31 can be driven to rotate, and then the left and right rudders 32 can be rotated to realize left and right steering; the left and right rudders 32 can be arranged below and / or above the steering mechanism 3. Steering vanes 331 are respectively sleeved on the left and right of the direction rod 330 and can be rotated by the left and right hands; when traveling underwater, upward or downward thrust can be obtained by rotating the up and down rudder.

[0027] The propulsion mechanism 5 includes a main beam 50, a pedal 51 slidably arranged on the main beam 50 and moving along the main beam 50, a transmission component 52 connected to the pedal 51 in a cooperative manner, and an automatic drag reduction propeller assembly 53 located at the output end of the transmission component 52. The blades 54 of the automatic drag reduction propeller assembly 53 can rotate and change angles according to the water flow thrust, so that the automatic drag reduction propeller assembly 53 generates a thrust in a single direction. The main beam 50 is fixedly connected to the support main frame. When in use, the operator sits in the cockpit and pedals the pedal 51 manually, so that the pedal 51 moves along the main beam 50. During the movement, the transmission component 52 is driven to move synchronously. The rotational driving force generated by the transmission component 52 drives the automatic drag reduction propeller assembly 53 to rotate, and then generates a thrust to propel the hull to travel. An electric thruster 8 is arranged at the end of the main beam 50 of the propulsion mechanism 5.

[0028] The propulsion mechanism 5 can be of various structures. Embodiment 1: For example Figure 3As shown in the figure, in this propulsion mechanism 5, the sliding structure between the pedal 51 and the main beam 50 adopts the cooperation of a slider 56 and a slide rail 55. Specifically, slide rails 55 are arranged on both sides of the main beam 50 along its length direction, and the slider 56 is slidably engaged with the slide rails 55. The pedal 51 is arranged on the slider 56. At the same time, the transmission component 52 between the pedal 51 and the automatic drag reduction propeller assembly 53 adopts a rack 520 - gear transmission structure. Specifically, the transmission component 52 includes a rack 520 arranged on the slider 56, a gear box 521 arranged on the main beam 50, a gear set 522 located in the gear box 521 and meshed with the rack 520, and a transmission shaft 523 arranged at the output end of the gear set 522. The transmission shaft 523 is cooperatively connected with the main shaft 530 of the automatic drag reduction propeller assembly 53. A rack stopper 524 is arranged at the rear of the main beam 50, and the rack stopper 524 can ensure that the rack 520 accurately moves along with the slider 56, realizing the precise meshing of the gears in the gear set 522. The gear set 522 can adopt structures such as a worm and worm gear, and the meshing of two sets of helical gears. During operation, when the operator drives the pedal 51 to move the slider 56, it will drive the rack 520 to perform a linear movement. The movement of the rack 520 drives the gear set 522 in the gear box 521 to rotate and do work, thereby converting the linear motion into a rotational motion. An automatic drag reduction propeller assembly 53 is connected to the output end of the gear set 522, thereby driving the automatic drag reduction propeller assembly 53 to rotate, providing thrust for the device, and pushing the device forward.

[0029] As Figure 4 shown, Embodiment 2: In this embodiment, the transmission component 52 of the propulsion mechanism 5 adopts a chain 527 - sprocket transmission structure. Specifically, the transmission component 52 includes a front sprocket 525 arranged at one end of the main beam 50, a rear sprocket 526 arranged at the other end of the main beam 50, a chain 527 cooperatively wound around the front sprocket 525 and the rear sprocket 526, a gear box 521 arranged on the main beam 50, a gear set 522 located in the gear box 521 and coaxially arranged with the rear sprocket 526, and the slider 56 is arranged on the chain 527 through a chain buckle 528. The gear set 522 can adopt structures such as a worm and worm gear, and the meshing of two sets of helical gears. The pedal 51 can slide back and forth on the guide rail through the slider 56. The chain 527 is wound around the front sprocket 525 and the rear sprocket 526. A chain buckle 528 is fixed on the slider 56, and one section of the chain 527 is fixed on the chain buckle 528. The pedal 51 is installed on the slider 56. When the pedal 51 drives the slider 56 to slide, the chain buckle 528 on the slider 56 drives the chain 527 to move, causing the front sprocket 525 and the rear sprocket 526 to rotate synchronously. The rear sprocket 526 transmits the lateral rotational force through the gear set 522, and then the automatic drag reduction propeller assembly 53 arranged at the output end of the gear set 522 rotates, thereby generating thrust and pushing the device forward.

[0030] As Figures 5 to 6As shown in the figure, the automatic drag reduction propeller assembly 53 includes a main shaft 530 fitted and connected to the output end of the transmission assembly 52, a blade mounting shaft 531 provided on the main shaft 530, and blades 54 fitted and mounted on the blade mounting shaft 531. A limiting groove 532 is formed between adjacent blade mounting shafts 531, and a limiting block 533 is arranged in the limiting groove 532. The rotation angle of the blade 54 is limited by the left limiting edge 534 and the right limiting edge 535 of the limiting block 533. The blade 54 is provided with an eccentrically arranged and axially penetrating mounting shaft hole 540, and the blade 54 is mounted by fitting the mounting shaft hole 540 on the blade mounting shaft 531. The blade 54 is divided into two blade units 541 with inconsistent areas with the axis of the mounting shaft hole 540. Among them, the blade unit 541 with a smaller area is the front blade unit 541, and the blade unit 541 with a larger area is the rear blade unit 541. When the main shaft 530 rotates, the front blade unit 541 and the rear blade unit 541 will receive different water thrusts, so that the blade rotates around the blade shaft; when turning left, the blade 54 will turn left under the action of water power and rotate a certain angle restricted by the left limiting edge; when the main shaft 530 turns right, the blade 54 will turn right under the action of water power and rotate a certain angle restricted by the right limiting edge. Therefore, due to the specific structural design of the automatic drag reduction propeller assembly 53, when the blade 54 of the automatic drag reduction propeller assembly 53 rotates, no matter whether the blade 54 turns left or right by a certain angle, a thrust in a single direction will be formed to push the whole forward. In addition, when the automatic drag reduction propeller assembly 53 does not rotate and work, the blades will automatically be parallel to the water flow direction under the action of water power, thereby reducing the resistance underwater.

[0031] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
