Abstract
Description
Technical Field
[0001] This invention relates to the field of lifesaving projectile technology, and specifically discloses a rapid launching device for marine lifesaving equipment. Background Technology
[0002] Currently, the lifesaving equipment on existing marine vessels is mainly designed to be externally mounted or stored. When in use, it needs to be manually thrown onto the water, which is not only time-consuming and laborious, but also has a limited throwing range and is very inconvenient to use.
[0003] Patent application number 202210083245.X discloses a self-inflating lifebuoy launching device and method for water rescue, including a mounting plate, mounting frame, launching device, self-destructing device, line-laying reel system, and control cabinet. The self-destructing device includes a one-way self-inflating unit on the upper surface of the base, a one-way valve located within an air groove to control gas flow, a movably arranged air guide chamber within the air groove, and several air guide needles on the lower surface of the air guide chamber. Corresponding to the air guide needles, several gas cylinder racks are arranged inside the base, each containing a micro-high-pressure gas cylinder, which is fixed inside the base by a sealing plug. This invention uses a heat source sensing device to detect a heat source and, in conjunction with the self-inflating lifebuoy launching method, rapidly inflates the lifebuoy, improving launching accuracy and avoiding the problem of not being able to accurately launch the lifebuoy near the person in the water due to the inability to measure the distance from the shore, thus preventing the person from receiving rapid rescue. However, the existing self-inflating lifebuoy launching device for surface rescue still has some shortcomings in use. For example, although the self-inflating lifebuoy can be launched farther, its timely inflation cannot be effectively guaranteed. If the lifebuoy falls into the water and cannot be quickly inflated, the rescue will be ineffective. In addition, if there are multiple people in the water, after launching one self-inflating lifebuoy, another lifebuoy needs to be attached, which prevents the launching device from quickly and continuously launching multiple lifebuoys, increasing the rescue time. Therefore, in order to address the above-mentioned shortcomings of the existing self-inflating lifebuoy launching device for surface rescue, this application proposes a newly designed rapid launching device for marine rescue equipment.

[0011] As a further feature of the above solution, the storage cylinder is provided with a replacement port, and one side of the replacement port is rotatably connected to an arc-shaped sealing plate via a hinge. The lower end of the motor shaft of the feeding motor is connected to a plug sleeve, and the upper end of the shaft is provided with a plug connector that matches the plug sleeve. The plug connector and the plug sleeve are fixedly connected by a pin.
[0012] As a further provision of the above scheme, the acceleration projectile assembly includes a push block that moves along the projectile acceleration channel.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0019] 1. The rapid launching device for marine lifesaving equipment disclosed in this invention operates by a winding traction mechanism and a drive assembly winding up the traction rope. The traction rope then pulls the launching assembly backward along the launching acceleration channel, compressing the first spring to store momentum. Simultaneously, a current of appropriate magnitude is supplied to the launching electromagnet based on the distance the lifebuoy is to be launched, generating a strong magnetic repulsion force between the electromagnet and the permanent magnet. When launching is required, the drive assembly is disconnected from the winding traction mechanism. Under the action of the first spring's restoring force and the magnetic repulsion force, the lifebuoy is rapidly propelled and accelerated along the launching acceleration channel, ensuring it possesses sufficient kinetic energy upon release. This allows for precise launching of the lifebuoy onto the corresponding water surface area. Compared to existing technologies, this rapid launching device for marine lifesaving equipment allows for precise control based on the launching position and distance, enabling the lifebuoy to be launched farther and at a more accurate launch point.
[0020] 2. This invention further incorporates a special continuous feeding mechanism. When multiple people fall into the water and lifebuoys need to be launched for rescue, the continuous feeding mechanism only needs to control the feeding motor to rotate forward and backward once each time. During its rotation, the change in magnetic force between the magnetic components controls the radial movement of the telescopic rod. When the telescopic rod extends radially outward, it can hold and limit the lifebuoy at the top of the storage cylinder. When the telescopic rod moves radially inward, it can discharge the lifebuoy at the bottom of the storage cylinder and drop it into the launching acceleration channel through the feeding port. Then, the accelerating launching component applies launching kinetic energy to it. The entire continuous feeding mechanism has a novel and ingenious structural design, which can realize the continuous launching of multiple lifebuoys in emergency situations, effectively improving the rescue effect for people who have fallen into the water.

[0030] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be given below with reference to the accompanying drawings, which illustrate several embodiments of the present invention. However, the present invention can be implemented in different forms and is not limited to the embodiments described in the text. Rather, these embodiments are provided to make the disclosure of the present invention more thorough and complete.
[0031] Example 1
[0032] Example 1 discloses a rapid launching device for marine lifesaving equipment, see attached drawing. Figure 1-4 The main body of the equipment includes a base 1 and a control box 6. The control box 6 can control the operation of the entire equipment. The base 1 can be fixed to the ship with bolts, or casters can be installed at its bottom to make the whole unit easy to move.
[0033] A projectile channel plate 2 is rotatably connected to the upper surface of the base 1. Specifically, a rotating support block 12 is welded and fixed to the upper surface of the base 1. A protruding plate 13, rotatably connected to the rotating support block 12 via a rotating shaft, is welded to the lower surface of the projectile channel plate 2. An adjustment mechanism connected to the rotating shaft is provided on one side of the rotating support block 12. The adjustment mechanism includes a worm gear drive 14 connected to the outer end of the rotating shaft. An operating handwheel 15 is connected to the outer end of the worm in the worm gear drive 14. When launching a lifebuoy, the operator can first rotate the operating handwheel 15, and then adjust the tilt angle of the projectile channel plate 2 under the transmission of the worm gear drive 14. After adjustment, the projectile channel plate 2 can be fixed by the self-locking action of the worm gear.
[0034] Reference Appendix Figure 4 Appendix Figure 7 and attached Figure 8A projectile acceleration channel 201 is provided at the front end of the projectile channel plate 2. A feeding port 202, which communicates with the front end of the projectile acceleration channel 201, is provided on the upper surface of the projectile channel plate 2. A limiting slide 203 is provided on the lower surface of the projectile acceleration channel 201, located behind the feeding port 202. An acceleration projectile assembly 3 is slidably and limitingly disposed in the projectile acceleration channel 201 above the limiting slide 203, and a first spring 4 is provided between the acceleration projectile assembly 3 and the rear end of the projectile acceleration channel 201.
[0035] In its specific design, the acceleration and projection assembly 3 includes a push block 301 that moves along the projection acceleration channel 201. The lower surface of the push block 301 is provided with a base plate 302 that interacts with the limiting slide 203. A vertically positioned limiting pin 306 is connected to the front end of the base plate 302 via a third spring 303, and a magnetic end block 304 is connected to the lower end of the limiting pin 306. Simultaneously, a pull-down electromagnet 305 is provided on the lower surface of the projection cavity plate 2 directly below the feeding port 202, located directly below the moving path of the magnetic end block 304. When the pull-down electromagnet 305 is not energized, the limiting pin 306 extends upwards to a certain height. Then, under the action of the limiting pin 306 and the push block 301, the lifebuoy 100 can be pulled towards the rear end of the projection acceleration channel 201. In addition, in order to control the amount of kinetic energy applied to the lifebuoy 100 by the acceleration and launching assembly 3, this embodiment 1 also provides a launching electromagnet 5 extending into the launching acceleration channel 201 and aligned with the front and rear of the acceleration and launching assembly 3 at the rear end of the launching cavity plate 2. Furthermore, a permanent magnet block 300 interacting with the launching electromagnet 5 is provided on the rear end surface of the pushing block 301 in the acceleration and launching assembly 3.
[0036] Reference Appendix Figure 1 and attached Figure 4 A winding traction mechanism 7 is provided on the upper surface of the base 1 located behind the projectile channel plate 2. A traction rope 8 is connected to the winding traction mechanism 7, which extends into the projectile acceleration channel 201 and is connected to the acceleration projectile assembly 3. A drive assembly 9 that can be connected and disconnected is provided on the side end of the winding traction mechanism 7.
[0037] In its specific design, the winding traction mechanism 7 includes a wheel frame 701 fixed on the base 1. A winding reel 702 is rotatably connected to the wheel frame 701 via an axle, and a first toothed disc 703 is provided on the side end of the axle extending out of the wheel frame 701. The drive assembly 9 includes a sliding block 901 fixed to the upper surface of the base 1. A drive motor 902 is slidably mounted on the sliding block 901, and a telescopic device 903 is provided on the side end of the sliding block 901 to push the drive motor 902 toward the first toothed disc 703. A second toothed disc 904 that meshes with the first toothed disc 703 is also provided on the motor shaft of the drive motor 902.
[0038] Finally, a through hole connected to the projectile acceleration channel 201 is provided on the rear end face of the projectile channel plate 2. A guide wheel 11 is provided on the rear end face of the projectile channel plate 2 below the through hole. The traction rope 8 on the winding wheel 702 enters the through hole through the guide wheel 11 and is connected to the acceleration projectile assembly 3.
[0039] In the use of the rapid launching device for marine life-saving equipment disclosed in Embodiment 1, the life ring 100 is loaded into the launching acceleration channel 201 through the feeding port 202, and the rear end of the life ring 100 is engaged between the limiting pin 306 and the pushing block 301.
[0040] Next, the telescopic device 903 is activated, pushing the drive motor 902 towards the winding traction mechanism 7, thereby engaging the first toothed disc 703 with the second toothed disc 904. Then, the drive motor 902 causes the winding wheel 702 to rotate, thereby winding up the traction rope 8. During the winding process of the traction rope 8, the accelerating launching component 3 is pulled backward along the launching acceleration channel 201, causing the first spring 4 to be compressed and stored, until the accelerating launching component 3 moves to the rear end, and the lifebuoy 100 is also simultaneously pulled to the rear end of the launching acceleration channel 201.
[0041] When it is necessary to launch a lifebuoy to rescue a person who has fallen into the water, first adjust the tilt angle of the launching cavity plate 2 by turning the operating handwheel 15, and then pass a current of a corresponding magnitude into the launching electromagnet 5 according to the distance of the person who has fallen into the water, so that the launching electromagnet 5 and the permanent magnet block 300 generate a repulsive force of a corresponding magnitude.
[0042] Once everything is ready, the telescopic device 903 is directly controlled to retract, causing the drive motor 902 to move away from the winding traction mechanism 7. Then, the first toothed disc 703 separates from the second toothed disc 904. Under the action of magnetic repulsion and the elastic restoring force of the first spring 4, the push block 301 will push the lifebuoy forward quickly. When the push block 301 moves to directly below the feeding port 202, the pull electromagnet 305 will generate a magnetic attraction force on the magnetic end block 304, causing the limiting pin 306 to move down, releasing the restriction on the lifebuoy 100. This allows the accelerated lifebuoy 100 to finally be launched from the projectile acceleration channel 201 and then projected onto the water surface near the person who fell into the water.
[0043] Example 2
[0044] Example 2 discloses a rapid launching device for maritime lifesaving equipment that is further optimized and improved based on the technical solution in Example 1. The similarities between it and Example 1 will not be described again.
[0045] Reference Appendix Figure 1 Appendix Figure 4 Appendix Figure 5 Appendix Figure 6 and attached Figure 9 In this embodiment 2, a continuous feeding mechanism 10 is also provided on the upper surface of the ejection channel plate 2 located above the feeding port 202. In a specific design, the continuous feeding mechanism 10 includes a storage cylinder 101 arranged concentrically with the feeding port 202. A feeding motor 102 is provided on the upper surface of the storage cylinder 101. The lower end of the feeding motor 102 is connected to a vertically downward shaft 103, and a disc 104 is concentrically connected to the lower end of the shaft 103.
[0046] At least two radial through rods 105 are evenly connected to the outer circumference of the disc 104. In this illustration, three radial through rods 105 are provided. A telescopic movable rod 106 is inserted into each radial through rod 105, and a second spring 107 is provided between the inner end of the telescopic movable rod 106 and the radial through rod 105. A magnetic suction assembly is also provided at the lower end of the storage cylinder 101 to drive all the telescopic movable rods 106 to move radially synchronously. This magnetic suction assembly includes magnetic blocks 108 located at the outer ends of the telescopic movable rods 106, and adsorption magnets 109 radially aligned with each magnetic block 108 are provided at the lower end of the outer circumference of the storage cylinder 101.
[0047] Finally, in order to facilitate batch feeding of life rings 100, this embodiment 2 also provides a replacement port 110 on the storage cylinder 101. One side of the replacement port 110 is connected to an arc-shaped sealing plate 111 via a hinge. Then, a plug sleeve 112 is connected to the lower end of the motor shaft of the feeding motor 102. The upper end of the shaft 103 is provided with a plug connector 113 that matches the plug sleeve 112, and the plug connector 113 and the plug sleeve 112 are fixedly connected by a pin.
[0048] In this embodiment 2, the continuous feeding mechanism 10, through the above-mentioned arrangement, concentrically sleeves multiple lifebuoys 100 in the shaft 103. At this time, under the action of the magnetic attraction component, the telescopic movable rod 106 extends radially outward to its longest length, so that the distance between the outer end of the telescopic movable rod 106 and the center of the disc 104 is greater than the inner radius of the lifebuoy 100. Therefore, it can stably support multiple lifebuoys 100 on the storage cylinder 101.
[0049] After the lifebuoy 100 in the ejection cavity plate 2 is ejected and everything is reset, the feeding motor 102 will rotate at a certain angle and then rotate to reset. During this process, due to the disappearance or reduction of the magnetic attraction force of the magnetic attraction component, all the telescopic movable rods 106 synchronously retract radially to a radius smaller than the inner circle radius of the lifebuoy 100. At this time, the lifebuoy 100 at the bottom of the storage cylinder 101 will fall into the ejection acceleration channel 201 to prepare for rapid acceleration and ejection. After the feeding motor 102 rotates to reset, the telescopic movable rods 106 can hold the lifebuoy above again to prevent it from falling into the ejection acceleration channel 201. This process continues until the next ejection, at which point the feeding motor 102 can be run again to achieve automatic feeding and continuous ejection of the lifebuoy.
[0050] The present invention has been described by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
