DETAILED DESCRIPTION

[0026] The principles and features of the present invention are described below 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.

[0027] like Figures 1 to 4 As shown, a simple semi-submersible underwater search and operation device includes a supporting main frame 1 having at least one cabin 100, a buoyancy component 2 arranged on the upper part of the supporting main frame 1, a propulsion mechanism 3 arranged at the tail end of the supporting main frame 1 and used to provide thrust, and a steering mechanism 4 for changing the movement direction of the device. The cabin 100 on the supporting main frame 1 can be one or more, and can be arranged according to actual use needs. In addition, the cabin 100 can be a cabin-type structure or a seat-type structure. A cabin close to the propulsion mechanism is a cockpit. The cabin and / or cockpit can be one or more, and can be arranged below or above the water surface.

[0028] The supporting main frame 1 includes a base frame 10 and a plurality of support frames 11 which are respectively arranged on both sides of the base frame 10 and are spaced apart from each other. The buoyancy component 2 is arranged on the support frame 11. The cockpit 100, the propulsion mechanism 3 and the steering mechanism 4 are respectively arranged on the base frame 10. A detachable roof 12 is provided on the top of the support frame 11 to provide rain and sun protection.

[0029] The buoyancy component 2 adopts the existing buoy structure, which can be one or more, and its buoyancy is much greater than the overall weight of the device. In addition, the buoyancy component 2 can be set on the upper part of the interior or on both sides of the exterior of the support frame 11, and its setting position is installed according to actual use needs. The propulsion mechanism 3 can be a human propulsion mechanism 3 and an electric propulsion mechanism 3. Among them, the electric propulsion adopts the existing motor-driven blade rotation structure. The human propulsion mechanism 3 adopts the structure of the pedal 31. In addition, according to actual needs, the electric propulsion mechanism 3 can also be set on the side of the support frame 11 to improve the propulsion effect.

[0030] like Figure 3 As shown, propellers 20 can also be set on both sides of the support frame 11, and the cabin or seat can be set on the base frame 10, or it can be set on the upper part of the support frame 11 and flush with the buoyancy component 2 to achieve underwater or surface travel.

[0031] like Figure 5 As shown, the propulsion mechanism 3 includes a main beam 30, a pedal 31 slidably arranged on the main beam 30 and moving along the main beam 30, a transmission assembly 32 connected to the pedal 31, and an automatic drag reduction propeller assembly 33 located at the output end of the transmission assembly 32, and the blade 34 of the automatic drag reduction propeller assembly 33 can rotate at a fixed angle according to the impact of the water flow, so that the automatic drag reduction propeller assembly 33 generates a thrust in a single direction. The main beam 30 is fixedly connected to the supporting main frame 1. When in use, the operator sits in the cockpit 100 and steps on the pedal 31 manually, so that the pedal 31 moves along the main beam 30, and drives the transmission assembly 32 to move synchronously during the movement. The rotational driving force generated by the transmission assembly 32 drives the automatic drag reduction propeller assembly 33 to rotate, thereby generating thrust to propel the hull.

[0032] The propulsion mechanism 3 can be of various structures. Example 1: Figure 5As shown, in the propulsion mechanism 3, the sliding structure between the pedal 31 and the main beam 30 adopts the cooperation of the slider 36 and the slide rail 35. Specifically, the slide rails 35 are arranged on both sides of the main beam 30 and along its length direction. The sliders 36 are slidably matched on the slide rails 35, and the pedal 31 is arranged on the slider 36. At the same time, the transmission assembly 32 between the pedal 31 and the automatic drag reduction propeller assembly 33 adopts a transmission structure of a rack 320 gear. Specifically, the transmission assembly 32 includes a rack 320 arranged on the slider 36, a gear box 321 arranged on the main beam 30, a gear set 322 located in the gear box 321 and meshing with the rack 320, and a transmission shaft 323 arranged at the output end of the gear set 322, and the transmission shaft 323 is connected with the main shaft 330 of the automatic drag reduction propeller assembly 33. A rack stopper 324 is provided at the rear of the main beam 30, and the rack stopper 324 can ensure that the rack 320 moves accurately with the slider 36, so as to achieve accurate engagement of the gears in the gear set 322. The gear set 322 can adopt a structure such as a worm gear, two sets of helical gears meshing, etc. During operation, when the operator drives the pedal 31 to move the slider 36, the rack 320 will be driven to move linearly, and the movement of the rack 320 will drive the gear set 322 in the gear box 321 to rotate and do work, thereby converting the linear motion into rotational motion. The output end of the gear set 322 is connected to the automatic drag reduction propeller assembly 33, which in turn drives the automatic drag reduction propeller assembly 33 to rotate, provide thrust for the device, and push the device forward.

[0033] like Figure 6As shown, embodiment 2: In this embodiment, the transmission assembly 32 of the propulsion mechanism 3 adopts a transmission structure of a chain 327 sprocket. Specifically, the transmission assembly 32 includes a front sprocket 325 arranged at one end of the main beam 30, a rear sprocket 326 arranged at the other end of the main beam 30, a chain 327 arranged around the front sprocket 325 and the rear sprocket 326, a gear box 321 arranged on the main beam 30, a gear set 322 located in the gear box 321 and coaxially arranged with the rear sprocket 326, and a transmission shaft 323 arranged at the output end of the gear set 322, the transmission shaft 323 is connected with the main shaft 330 of the automatic drag reduction propeller assembly 33, and the slider 36 is arranged on the chain 327 through a chain buckle 328. The gear set 322 can adopt a structure such as a worm gear, two sets of helical gears meshing, etc. The pedal 31 can slide forward and backward on the guide rail through the slider 36, the chain 327 is wound around the front sprocket 325 and the rear sprocket 326, the slider 36 is fixed with a chain buckle 328, one section of the chain 327 is fixed on the chain buckle 328, and the slider 36 is equipped with the pedal 31. When the slider 36 is driven to slide by the pedal 31, the chain buckle 328 on the slider 36 drives the chain 327 to move, so that the front sprocket 325 and the rear sprocket 326 rotate synchronously. The rear sprocket 326 transmits the lateral rotation force through the gear set 322, and then the automatic drag reduction propeller assembly 33 set at the output end of the gear set 322 rotates, thereby generating thrust, and the driving device moves forward.

[0034] like Figures 7 and 8As shown, the automatic drag reduction propeller assembly 33 includes a main shaft 330 connected to the output end of the transmission assembly 32, a blade installation shaft 331 arranged on the main shaft 330, and a blade 34 installed on the blade installation shaft 331. A limiting groove 332 is formed between adjacent blade installation shafts 331, and a limiting block 333 is arranged in the limiting groove 332. The rotation angle of the blade 34 is limited by the left limiting edge 334 and the right limiting edge 335 of the limiting block 333. The blade 34 is provided with an eccentrically arranged and axially penetrating mounting shaft hole 340, and the mounting shaft hole 340 is matched with the blade installation shaft 331 to realize the installation of the blade 34. The blade 34 is divided into two blade units 341 with different areas with the mounting shaft hole 340 as the axis, wherein the blade unit 341 with a smaller area is the front blade unit 341, and the blade unit 341 with a larger area is the rear blade unit 341. When the main shaft 330 rotates, the front blade unit 341 and the rear blade unit 341 will be subjected to different water impact forces, so that the blades rotate around the blade shaft; when turning left, the blade 34 will turn left under the action of water force, and be limited to rotate at a certain angle by the limiter; when the main shaft 330 turns right, the blade 34 will turn right under the action of water force, and be limited to rotate at a certain angle by the limiter. Therefore, based on the specific structural design of the automatic drag reduction propeller assembly 33, when the blade 34 of the automatic drag reduction propeller assembly 33 rotates, no matter the blade 34 turns left or right at a certain angle, it will form a thrust in a single direction to drive the whole forward. In addition, when the automatic drag reduction propeller assembly 33 is not rotating, the blades will be parallel to the direction of the water flow under the action of water force, thereby reducing the resistance due to underwater.

[0035] like Figure 4 , Fig. 9 As shown, the steering mechanism 4 includes a steering arm 40 rotatably arranged on the base frame 10 supporting the main frame 1, a steering connecting rod 41 arranged on the steering arm 40, a rudder connecting rod 42 arranged at the end of the steering connecting rod 41 away from the steering arm 40, and a rudder 43 arranged on the rudder connecting rod 42, and a steering handle 44 is arranged on the steering arm 40. The steering arm 40 is hinged on the supporting main frame 1 through a rotating shaft to realize the rotation function. When a steering operation is required, the operator operates the steering handle 44 to drive the steering arm 40 to rotate, and the steering arm 40 rotates to drive the steering connecting rod 41 to push the rudder connecting rod 42 to make the rudder 43 swing, thereby realizing the hull steering function.
