Description

Technical Field

[0001] The present invention belongs to the technical field of maritime rescue, and specifically relates to a lifebuoy throwing device. Background Art

[0002] With the increasing frequency of global marine activities, the demand for maritime rescue is constantly increasing. As an emerging rescue tool, marine drones have gradually attracted attention due to their unique advantages. First of all, marine drones have the ability to reach the scene at high altitude, remotely, and quickly, and can quickly lock the rescue target.

[0003] However, when the current marine drones on the market throw rescue equipment, they usually use the method of hanging one or more lifebuoys with ropes. Although this method is simple, there are many deficiencies in actual applications. First of all, hanging multiple lifebuoys with ropes will seriously affect the flight stability of the drone. As the number of hanging lifebuoys increases, the center of gravity distribution of the drone will change, resulting in difficult control of the flight attitude and increasing the risk of flight accidents. Secondly, the method of hanging with ropes cannot achieve separate throwing of multiple targets. In rescue missions, it is often necessary to rescue multiple targets simultaneously or continuously, but the existing drone throwing methods usually can only release all lifebuoys at one time and cannot achieve precise throwing of each target.

[0031] It should be noted that the suspension cylinder 100 can be fixed on the drone hanger by welding, or can be hung on the drone by a hook. The specific method is the prior art and will not be elaborated here.

[0032] The release member 200 includes a first cross bar 201 and a first vertical plate 202 arranged on the first cross bar 201. A first through hole 101a is arranged on the suspension cylinder 100, and the first cross bar 201 passes through the first through hole 101a.

A first elastic band 204 is arranged at the end of the first cross bar 201, and the other end of the first elastic band 204 is connected to the outer wall of the suspension cylinder 100.

[0034] A first driving disk 104 is arranged on the rotating shaft 103, and a first groove 104a is arranged on the first driving disk 104. The other end of the first cross bar 201 abuts against the outer side wall of the first driving disk 104.

[0035] A spherical ball is arranged at the other end of the first cross bar 201, and the spherical ball contacts the outer side wall of the first driving disk 104.

[0036] The limiting member 300 includes a second cross bar 301 and a second vertical plate 302 arranged on the second cross bar 301. A second through hole 101b is arranged on the suspension cylinder 100, and the second cross bar 301 passes through the second through hole 101b.

[0037] A second spring 303 is arranged on one side of the second vertical plate 302 and is connected to the inner wall of the suspension cylinder 100. A second elastic band 304 is arranged at the end of the second cross bar 301, and the other end of the second elastic band 304 is connected to the outer wall of the suspension cylinder 100.

[0038] A second driving disk 105 is arranged on the rotating shaft 103, and a second groove 105a is arranged on the second driving disk 105. The other end of the second cross bar 301 abuts against the outer side wall of the second driving disk 105, and the first groove 104a and the second groove 105a are arranged staggeredly.

[0039] The suspension member 400 includes a third cross bar 401 and a third vertical plate 402 disposed on the third cross bar 401. One end of the third vertical plate 402 is provided with a rubber block 403. A square groove 101c is provided on the suspension cylinder 100, and the rubber block 403 is disposed in the square groove 101c.

[0040] A third driving disk 106 is provided on the rotating shaft 103. A third groove 106a is provided on the third driving disk 106. The other end of the third cross bar 401 abuts against the outer side wall of the third driving disk 106, and the positions of the first groove 104a and the third groove 106a partially correspond.

[0041] It should be noted that the third driving disk 106 and the first driving disk 104 are used to control the outward or inward movement of the release member 200, the second driving disk 105 is used to control the outward or inward movement of the limiting member 300, and the suspension member 400 is used to control the outward or inward movement of the suspension member 400.

[0042] Refer to Figure 5 , with the outward state recorded as 1 and the inward state recorded as 0, ignoring the transition process, draw the state timing diagrams of the release member 200, the limiting member 300, and the suspension member 400.

[0043] The specific working principle is as follows: In the initial state, the release member 200 is outward, the limiting member 300 is outward, and the suspension member 400 is inward. At this time, the lowermost lifebuoy 500 is between the first cross bar 201 and the second cross bar 301; subsequently, the release of the lifebuoy is started. The release member 200 moves inward, the limiting member 300 moves outward, and the suspension member 400 moves outward, then the lowermost lifebuoy 500 drops and is released, and the other lifebuoys above remain stationary; subsequently, the release member 200 moves outward, the limiting member 300 moves inward, and the suspension member 400 moves outward. At this time, the original second-lowest lifebuoy drops downward and fills above the release member 200, and the remaining lifebuoys 500 are pushed against by the outward movement of the suspension member 400; finally, the release member 200 is in the outward state, the limiting member 300 is in the outward state, and the suspension member 400 is inward. At this time, the lowermost lifebuoy is separated and returns to the same state as the initial state. When released again, only the lowermost lifebuoy will be released.

[0044] It should be noted that since two release members 200, two limiting members 300, and two suspension members 400 are all arranged in a circumferential array, therefore Figure 5 the period in

[0045] is 180°.

[0046] It should be understood that, during the development of any actual implementation, such as in any engineering or design project, a large number of specific implementation decisions can be made. Such development efforts may be complex and time-consuming, but for those of ordinary skill in the art who benefit from this disclosure, without undue experimentation, such development efforts will be routine work of design, fabrication, and production.

[0047] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
