Description
Technical Field
[0001] The utility model relates to the technical field of marine rescue speedboats, in particular to a high-speed cruising rescue speedboat. Background Art
[0002] With the rapid development of science and technology, there are more and more types of transportation. When people travel by plane or ship, it is inevitable that they will fall into the sea in accidents. After these accidents, it is necessary to conduct maritime search and rescue, rescue and salvage work in the accident area, which requires the use of maritime rescue speedboats. In order to improve the rescue efficiency, the existing maritime rescue speedboats are mainly maneuverable, mostly consisting of a hull plus an engine, and the engine is fixed to the stern through a frame. When performing a rescue, the engine works and the propeller rotates to push the hull forward quickly. In order to pursue maneuverability, traditional maritime rescue speedboats are often long, narrow and streamlined. When performing a rescue, especially when performing salvage work on personnel or equipment, the narrow hull is often not stable enough and is easy to tilt. In severe cases, it may even capsize, affecting the actual rescue effect of the speedboat. For this reason, we propose a high-speed cruising rescue speedboat. Utility Model Content

The inner walls of adjacent limiting grooves 44 are slidably connected to provide limiting and stabilizing effects for the retraction and extension of the stabilizing block 42. The retractable stabilizing mechanism 4 also includes an airbag 46, which is arranged inside the stabilizing block 42. The airbag 46 is an elastic rubber airbag, which can increase the buoyancy of the hull 1. The retractable stabilizing mechanism 4 also includes a transmission assembly 47, which includes a worm 471, a worm wheel 472, a reduction box 473 and a motor 474. A mounting groove 3 is opened in the middle of the upper end of the bottom wall of the hull 1. The worm 471 is rotatably connected to the inner rear side of the mounting groove 3. The worm wheel 472 is arranged at the upper end of the gear 43. 472 are meshed with the worm 471, the reduction box 473 is arranged at the middle rear side of the installation slot 3, the motor 474 is arranged at the middle front side of the installation slot 3, the input end of the motor 474 is electrically connected to the output end of the single-chip microcomputer 7, the rear end of the output shaft of the motor 474 is fixedly connected to the front end of the reduction shaft of the reduction box 473, and the output shaft of the reduction box 473 is fixedly connected to the middle part of the worm 471, providing a transmission effect for the retraction and release of the stabilizing block 42, and also includes an air pump 5, the air pump 5 is arranged at the lower end of the rear side of the left side wall of the hull 1, the input end of the air pump 5 is electrically connected to the output end of the single-chip microcomputer 7, and the airbags 46 are all connected by air.

The input end of the engine 6 is electrically connected to the output end of the single-chip microcomputer 7 to provide a stable propulsion effect for the movement of the hull 1. A retractable stabilizing mechanism is provided. When the rescue speedboat is moving, the stabilizing mechanism is retracted into the hull and will not increase the water resistance. The rescue speedboat can maintain high maneuverability. When salvage operations are required, the stabilizing mechanism can be quickly extended to improve the stability of the rescue speedboat by increasing the contact area with the water surface and the buoyancy of the entire hull, thereby improving the efficiency of rescue.
[0024] The working principle of a high-speed cruising rescue speedboat provided by the utility model is as follows: when using the high-speed cruising rescue speedboat for salvage and rescue work, the single-chip microcomputer 7 controls the motor 474 to operate, and the output shaft of the motor 474 drives the worm 471 to rotate forward through the reduction box 473. Because the worm gear 472 is meshed and connected with the worm 471, the worm gear 472 also rotates accordingly, driving the gear 43 to rotate synchronously. Because the rack plate 41 is meshed and connected with the gear 43, as the gear 43 rotates, the rack plate 41 moves outward, and the stabilizing block 42 also moves outward accordingly. The limiting column 45 provides a stabilizing and limiting effect for the movement of the stabilizing block 42 until the stabilizing block 42 moves to a suitable position. The single-chip microcomputer 7 controls the air pump 5 to operate, and the air pump 5 pumps air into the airbag 46. The airbag 46 is filled with air and expands to increase the overall buoyancy of the hull. At this time, the stabilizing block 42 and the airbag 46 extend. When the rescue boat is out of the hull 1, the contact area between the hull and the water surface increases, and the buoyancy of the hull also increases, which can make the hull more stable, thereby performing salvage and rescue work more quickly and stably. When the salvage work is completed, it is necessary to maintain the high maneuverability of the rescue speedboat, and the air in the airbag 46 needs to be released and the stabilizing block 42 needs to be retracted to reduce the water resistance. The single-chip microcomputer 7 controls the motor 474 to operate, and the output shaft of the motor 474 drives the worm 471 to reverse through the reduction box 473, and the worm gear 472 also rotates accordingly, driving the gear 43 to rotate synchronously. As the gear 43 rotates, the rack plate 41 moves inward, and the stabilizing block 42 also moves inward accordingly, until the stabilizing block 42 is completely retracted into the hull 1, and the stabilizing block 42 forms a whole with the surface of the hull 1. At this time, the single-chip microcomputer 7 controls the engine 6 to work, and the engine 6 can push the hull 1 to move with low water resistance, and the rescue speedboat can still maintain high maneuverability.
[0025] It is worth noting that the single chip microcomputer 7 disclosed in the above embodiment is an S7-200 single chip microcomputer, the motor 474 is a YY90-220-120NAC motor, the air pump 5 is a JY-CQB-H1 air pump, and the engine 6 is a YC5-7500 engine. The single chip microcomputer 7 controls the operation of the motor 474, the air pump 5 and the engine 6 using methods commonly used in the prior art.
