Description

Technical Field

[0001] The invention relates to the technical field of lifesaving boats, in particular to a lifesaving boat with a propulsion device. Background Art

[0002] A lifeboat is another type of life-saving equipment used by crew members when a ship is in distress. It can be quickly released to the water surface and float on the water surface for people to board and wait for rescue. The inflatable life raft is simple to operate, easy to use, and small in size. It is a life-saving equipment that can be easily dropped to the water surface in a very short time. These lifeboats have played an important role in maritime rescue. They have not only saved a large number of lives in war, but also continue to provide security for maritime safety in peacetime.

[0003] In the prior art, a lifeboat with a propulsion device can provide driving force through a propeller installed at the bottom of the rear end as an east-west system, thereby replacing human power for driving. However, since the power system is installed at the bottom, later inspection or maintenance requires the entire hull to be hoisted to the shore and then lifted and supported for inspection and treatment. Therefore, maintenance and inspection are difficult and inconvenient to operate. On the other hand, when rescuing people who fall into the water, the lifeboat needs people wearing it to help pull the people who fall into the water on the side of the boat onto the boat, so the scope of assistance is limited. The stability and traction effect provided by still throwing a lifebuoy are insufficient, and the center of gravity changes drastically during the boarding process, which makes it easy to tilt.

DETAILED DESCRIPTION

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0028] See also Figures 1 to 7 The present invention provides the following technical solutions: a lifeboat with a propulsion device, comprising a lifeboat body, the lifeboat body comprising a hull, a propulsion system, a transmission mechanism and a stabilizing component, a baffle is welded at the rear end of the hull, a limit plate is integrally formed on one side of the baffle, a slide groove is provided on the inner side of the limit plate, a support shaft is inserted through the top of the propulsion system, both ends of the support shaft are embedded in the inside of the slide groove, a transmission mechanism is welded at the rear end of the hull, the side of the propulsion system is against the surface of the transmission mechanism, and the propulsion system rotates around the top support shaft after being unlocked as a whole, a first motor and a second motor are screwed to the front end of the hull, a stabilizing component is installed at the bottom front end of the hull, a drive shaft is inserted through the top of the stabilizing component, and the top of the drive shaft passes upward from the front end of the hull and is fixedly connected to the output end of the first motor. The lifeboat with a propulsion device controls the entire hull to move and navigate through the thrust provided by the propulsion system at the rear end, and is used to provide rescue for people who fall into the water.

[0029] When the present invention is in use, the propulsion system is used to control the movement of the hull, and after it moves to the vicinity of the person who falls into the water, the first motor is started to drive the bottom stabilizing component to rotate, so that the rescue float is unfolded toward one side, until it extends outward from the bottom of the hull and extends to a longer range. At this time, the rescue float is used to expand the area providing support for the rescued person, so that the rescued person can be lifted and supported by the rescue float, and the second motor is also used to control the traction rope to drive the bottom counterweight to move, thereby ensuring that during the rescue process, after the rescued person is pressed onto the rescue float, additional pressure can be provided on the other side of the hull to reduce the instability caused by the rescued person being pressed on one side of the hull.

[0030] In this embodiment, the propulsion system includes a fixed plate and a drive chamber, the top of the fixed plate is integrally formed with the surface of the support shaft, the bottom of the fixed plate is integrally formed with a lower hanging plate, the drive chamber is welded to the end of the lower hanging plate, and the side of the fixed plate is welded with a locking screw. A propeller is installed inside the drive chamber, and there are four locking screws, and the end of each locking screw penetrates into the interior of the hull. The rear end propulsion system can be directly controlled on board to release the locked connection state and flip toward the top, so that it can be maintained and repaired on the water surface, without the need to lift the entire hull, reducing the difficulty of maintenance and repair operations.

[0031] Specifically, after the propeller is controlled to rotate by the drive compartment, power can be applied to the hull through the transmission mechanism to provide propulsion. When the propulsion system needs to be maintained and repaired later, the nut on the locking screw is first removed from the inside of the hull to release the control of the fixing plate, thereby driving the drive compartment at the bottom and the propeller to rotate around the top support shaft until the drive compartment is rotated to the top of the hull. At this time, the drive compartment flipped to the surface can be inspected and repaired on the hull, and after rotating to the top, the drive compartment can be controlled to move horizontally with the help of the slide slot, which improves flexibility.

[0032] In this embodiment, the transmission mechanism includes a transmission plate and a push plate. The bottom of the transmission plate is integrally formed with an end plate. The surface of the transmission plate is provided with a strip hole. The inner side of the end plate is integrally formed with a push plate. The top of the push plate is welded with a plurality of dispersion columns. The top of each dispersion column is welded to the bottom of the hull. The locking screw passes through the inside of the strip hole and is embedded into the inside of the hull. The dispersion columns are all located on the central axis of the bottom of the hull. The inner side of the lower hanging plate fits the surface of the end plate. The hull is connected to the propulsion system through the transmission mechanism. Therefore, the thrust generated by the propeller in the propulsion system can be evenly diffused to multiple positions of the center line of the bottom of the hull with the help of the transmission mechanism, and then the thrust is synchronously provided from multiple positions, which can make the thrust more uniform and improve the stability and reliability of the hull's travel.

[0033] Specifically, the thrust provided by the driving cabin can directly act on the transmission plate and the end plate at the bottom, and the power is transmitted to each dispersion column through the end plate with the help of a longer thrust plate. By dispersing the equivalent thrust from multiple positions on the bottom of the hull, the hull can be driven forward. Therefore, during the entire driving process, the thrust can be evenly distributed on the central axis of the bottom of the hull, avoiding the phenomenon of the hull tilting due to too single thrust point.

[0034] In this embodiment, the stabilizing assembly includes a driving shaft and a sliding plate, the surface of the driving shaft is keyed to a driving gear, the bottom of the driving shaft is integrally formed with a first rotating disk, the side of the first rotating disk is welded with a first rotating rod, the end of the first rotating rod is integrally formed with an inclined plate, and the sliding plate is mounted on the inclined plate. The side of the sliding plate is screwed with a connecting plate, the bottom of the connecting plate is screwed with a counterweight, and the sliding plate is pressed on the surface of the inclined plate through a roller at the bottom, and a hanging ring is provided on the side of the sliding plate, and a traction rope is connected to the hanging ring. A guide plate is welded on the side of the housing of the first motor, the traction rope passes through the hole provided on the guide plate, and the top of the traction rope is wound on the output shaft of the second motor, and the second motor is hidden inside the front end of the hull. When rescuing, the two sets of motor equipment at the front end can be started to unfold the stabilizing assembly at the bottom, and the scope of rescue can be expanded with the help of the floating plate, and the counterweight can also be controlled to unfold, so as to reduce the influence of the pressure generated by the rescued personnel on the center of gravity of the hull itself during the rescue process, and the stability and safety of the hull can be improved with the help of the stabilizing assembly.

[0035] A driven shaft is installed on the side of the driving shaft, a driven gear is keyed on the surface of the driven shaft, a second rotating disk is integrally formed at the bottom of the driven shaft, and a second rotating rod is welded on the side of the second rotating disk. A rescue floating plate is screwed to the end of the second rotating rod, the driving gear and the driven gear are meshed, the top of the driven shaft is embedded in the bottom of the hull through a bearing, and a gap is set between the first rotating disk and the second rotating disk.

[0036] Specifically, after the first motor 3 is started, the driving gear 29 will be driven to rotate through the driving shaft 28, and the driving gear 29 will cooperate with the driven gear 22 to drive the entire driven shaft 21 to rotate, and the second rotating disk 23 at the bottom of the driven shaft 21 will rotate the second rotating rod 24 on the side toward the outside of the hull 1 until the rescue floating board 25 is rotated to the side of the hull 1. At this time, the rescue floating board 25 can move with the hull 1 and provide support and guidance for the approaching rescued persons. In this process, the driving shaft 28 will also drive the first rotating rod 3 through the first rotating disk 30 at the bottom. 1 is rotated outward toward the other side of the hull 1, and after being pressed by the rescued person on the surface of the rescue floating plate 25, the second motor 2 is started at this time, and the traction rope 27 is rolled up and unwound by the second motor 2. At this time, the sliding plate 33 can slide toward the end along the inclined plate 32 because the traction rope 27 connected to the top no longer applies tension, and then pressure is applied from the end of the inclined plate 32 through the counterweight block 36 at the bottom. This pressure can reduce the pressing phenomenon of the rescued person on the rescue floating plate 25 from the other side of the hull 1, thereby improving the overall stability of the hull 1.

For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention.
