Abstract
Description
Technical Field
[0001] This utility model relates to the field of lifesaving device technology, specifically a lifesaving device for ships. Background Technology
[0002] A life ring is a type of water rescue equipment, typically made of cork, foam plastic, or other lightweight materials, covered with canvas, plastic, etc. It can be used as a rubber ring during swimming practice. Filled with air, the life ring is designed to provide buoyancy, helping people maintain buoyancy in the water and thus reducing the risk of drowning. Life rings must be equipped on ships, but traditional life rings are mostly sealed rings. However, when people fall into the water, they panic and cannot immediately place the life ring under their armpits when they receive it, which can easily lead to secondary drowning. To improve this situation, a new type of life-saving device for ships has been proposed.
[0003] As disclosed in the authorization announcement number CN113753201B, a ship lifesaving device includes a carrier, which has an arc-shaped structure and a connecting plate inside the carrier; the connecting plate has an arc-shaped structure; two air inlets are provided at the rear end of the carrier; the two air inlets are arc-shaped tubular structures; a set of guide rods are provided on both the left and right sides of the top of the carrier; the two sets of guide rods are cylindrical structures.
[0004] Although it achieves this, due to the arc-shaped structure of the carrier, there is a notch on the back of the carrier, which makes it easy for people who have fallen into the water to wedge the rescue device under their armpits through this notch. This makes the operation simple and convenient, and avoids the situation where people who have fallen into the water choose to lie on the rescue device because it is inconvenient to wedge the rescue device under their armpits, which would cause the rescue device to easily detach from under the person during the rescue and cause the person to fall into the water again.
[0005] However, it has not solved the problems of the existing life-saving devices being inconvenient to plug and use, and the external clamping and fixing of life-saving devices, which are not conducive to preventing secondary drowning caused by the inability of drowning people to place the life ring under their armpits in time. This affects the flexibility of life-saving devices and the convenience of taking them out. Utility Model Content
[0006] The purpose of this utility model is to provide a life-saving device for ships, in order to solve the problems mentioned in the background art, such as the inconvenience of plugging and using life-saving devices and the external clamping and fixing of life-saving devices, which are not conducive to preventing secondary drowning caused by the inability of people who have fallen into the water to place the life ring under their armpits in time, thus affecting the flexibility of use and the convenience of taking and placing the life-saving device.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a ship's lifesaving device, comprising a placement base and a drive motor. The drive motor is installed inside the placement base, and a drive shaft is installed at the output end of the drive motor. Three sets of rotating arms are arranged at equal intervals on the surface of the drive shaft. A linkage arm is provided at the end of each rotating arm away from the drive shaft, and a linkage shaft is provided at the end of each linkage arm near the rotating arm. The linkage arm is movably connected to the rotating arm through the linkage shaft. A connecting rod is provided at the end of each linkage arm away from the rotating arm. Three sets of limiting grooves are arranged at equal intervals on the surface of the placement base, and the connecting rod is slidably connected to the limiting groove. An arc-shaped plate is provided on the surface of each connecting rod, and the arc-shaped plate is movably connected to the connecting rod.
[0008] Preferably, the outer side of the placement seat is provided with a main airbag, and both ends of the main airbag are provided with auxiliary airbags.
[0009] Preferably, each of the auxiliary airbags is provided with a pin at the end closest to the main airbag, and the auxiliary airbag is movably connected to the main airbag through the pin. Furthermore, the ends of the two sets of auxiliary airbags furthest from the main airbag are respectively provided with a connecting sleeve and a connecting seat.
[0010] Preferably, a plug rod is installed at the end of the connecting seat away from the auxiliary airbag, and the plug rod is fixedly connected to the connecting seat.
[0011] Preferably, the plug rod extends into the interior of the connecting sleeve, and the plug rod is slidably connected to the connecting sleeve.
[0012] Preferably, limit rings are symmetrically installed on the side wall of the connecting sleeve, and the limit rings are fixedly connected to the connecting sleeve.
[0013] Preferably, each of the limiting rings is provided with a limiting rod inside, and the limiting rod is slidably connected to the limiting ring.
[0014] Preferably, the surface of each limiting rod is provided with a spring, and the two ends of the spring are respectively connected to the limiting ring and the limiting rod.
[0015] Compared with the prior art, the beneficial effects of this utility model are: the life-saving device not only realizes the convenient plug-in use of the life-saving device and the externally expanding clamping and fixing of the life-saving device, preventing the situation where the person who falls into the water cannot place the life ring under his armpit in time and thus causes secondary drowning, but also improves the flexibility of the life-saving device and the convenience of taking it out and putting it in.
[0016] (1) Install the placement seat on the ship. If someone falls into the water and needs rescue, first pull the limiting rod, then pull the connecting seat. The connecting seat will drive the insertion rod to be pulled out from inside the connecting sleeve, so that the two sets of auxiliary airbags are separated. Then connect the steel wire rope to the rope loop on the main airbag. Throw the device to the drowning location of the person in the water. The person in the water can take the two sets of auxiliary airbags, wrap them around their armpits, insert the insertion rod into the inside of the connecting sleeve, and the insertion rod will drive the limiting rod to move outward inside the limiting ring. When the spring is compressed, the connecting rod drives the auxiliary airbag to rotate around the pin shaft through the connecting seat. When the groove on the surface of the connecting rod moves to the position of the limiting rod, under the elastic action of the spring, the spring drives the limiting rod to be locked in the groove on the surface of the connecting rod, so as to lock the connecting rod into the inside of the connecting sleeve, thereby connecting the two sets of auxiliary airbags and forming a ring with the main airbag. This prevents secondary drowning caused by the inability of the person falling into the water to place the life ring under their armpits in time, and improves the flexibility of the life-saving device.
[0017] (2) After the life-saving device is used, place the device outside the arc plate, turn on the drive motor, and the drive motor drives the rotating arm to rotate through the drive shaft. The rotating arm drives the linkage arm to move through the linkage shaft. The linkage arm drives the connecting rod to slide inside the limit groove. The three sets of linkage rods drive the three sets of arc plates to move outward in sync. The arc plates contact the inner ring surface of the life-saving device, and under the continuous action of the drive motor, the arc plates fix the device, thereby improving the convenience of placement. This realizes the convenient outward clamping and fixing of the life-saving device, and improves the convenience of placing the life-saving device. Attached Figure Description

[0025] Please see Figure 1-5 An embodiment of this utility model provides a ship rescue device, including a placement base 1 and a drive motor 11. The drive motor 11 is installed inside the placement base 1 and plays a power driving role. A drive shaft 10 is installed at the output end of the drive motor 11.

A connecting rod 5 is provided at the end of the linkage arm 6 away from the rotating arm 8. Three sets of limiting grooves 9 are provided at equal intervals on the surface of the placement base 1. The connecting rod 5 is slidably connected to the limiting groove 9. An arc plate 3 is provided on the surface of the connecting rod 5. The arc plate 3 is movably connected to the connecting rod 5.
[0026] Install the placement seat 1 onto the vessel. If someone falls into the water and needs rescue, first pull the limiting rod 14, then pull the connecting seat 12. The connecting seat 12 will cause the insertion rod 17 to be pulled out from inside the connecting sleeve 13, separating the two sets of auxiliary airbags 4. Then connect the steel wire rope to the rope loop on the main airbag 2 and throw the device to the drowning location. The drowning person can then take the two sets of auxiliary airbags 4, wrap them around their armpits, and insert the insertion rod 17 into the connecting sleeve 13. Under the sliding limiting action of the limiting ring 15, the insertion rod 17 will cause the limiting rod 14 to move outward from inside the limiting ring 15. Simultaneously, the positioning rod 14 compresses the spring 16, and the connecting rod 17 drives the auxiliary airbag 4 to rotate around the pin 18 via the connecting seat 12. When the groove on the surface of the connecting rod 17 moves to the position of the limiting rod 14, under the elastic action of the spring 16, the spring 16 drives the limiting rod 14 to be locked in the groove on the surface of the connecting rod 17, thereby locking the connecting rod 17 into the inside of the connecting sleeve 13, connecting the two sets of auxiliary airbags 4 together and forming a ring with the main airbag 2, so as to prevent the person who falls into the water from being unable to place the life ring under their armpits in time, thus preventing secondary drowning and improving the flexibility of the life-saving device.
[0027] The main airbag 2 is provided on the outside of the placement seat 1. Auxiliary airbags 4 are provided at both ends of the main airbag 2. A pin 18 is provided at the end of the auxiliary airbag 4 closest to the main airbag 2. The auxiliary airbag 4 is movably connected to the main airbag 2 through the pin 18. A connecting sleeve 13 and a connecting seat 12 are respectively provided at the ends of the two sets of auxiliary airbags 4 away from the main airbag 2.
[0028] A connector rod 17 is installed at the end of the connector 12 away from the auxiliary airbag 4, and the connector rod 17 is fixedly connected to the connector 12. The connector rod 17 extends into the interior of the connector sleeve 13, and the connector rod 17 is slidably connected to the connector sleeve 13. Limiting rings 15 are symmetrically installed on the side wall of the connector sleeve 13, and the limiting rings 15 are fixedly connected to the connector sleeve 13.
[0029] Each limiting ring 15 is provided with a limiting rod 14 inside, and the limiting rod 14 is slidably connected to the limiting ring 15. Each limiting rod 14 is provided with a spring 16 on its surface, and the two ends of the spring 16 are respectively connected to the limiting ring 15 and the limiting rod 14.
[0030] After the life-saving device is used, it is placed outside the arc-shaped plate 3. The drive motor 11 is turned on, and the drive motor 11 drives the rotating arm 8 to rotate through the drive shaft 10. The rotating arm 8 drives the linkage arm 6 to move through the linkage shaft 7. Under the sliding cooperation between the linkage rod 5 and the limiting groove 9, the linkage arm 6 drives the linkage rod 5 to slide inside the limiting groove 9. The three sets of linkage rods 5 simultaneously drive the three sets of arc-shaped plates 3 to move outward. The arc-shaped plates 3 contact the inner ring surface of the life-saving device, and under the continuous action of the drive motor 11, the arc-shaped plates 3 fix the device, thereby improving the convenience of placement. This realizes convenient outward clamping and fixing of the life-saving device, improving the convenience of placing the life-saving device.
[0031] Working principle: The placement seat 1 is installed on the ship. If someone falls into the water and needs rescue, first pull the limiting rod 14, then pull the connecting seat 12. The connecting seat 12 drives the insertion rod 17 to be pulled out from the connecting sleeve 13, so that the two sets of auxiliary airbags 4 are separated. Then, connect the steel wire rope to the rope loop on the main airbag 2 and throw the device to the drowning location of the person. The person takes the two sets of auxiliary airbags 4, wraps them around their armpits, and inserts the insertion rod 17 into the connecting sleeve 13. Under the sliding limit of the limiting ring 15, the insertion rod 17 drives the limiting rod 14 to move outward inside the limiting ring 15. The limiting rod 14 simultaneously compresses the spring 16. At the same time, the insertion rod 17 drives the auxiliary airbags 4 to rotate around the pin 18 through the connecting seat 12. When the groove on the surface of the insertion rod 17 moves to the position of the limiting rod 14, the elastic action of the spring 16 drives the limiting rod. 14 is inserted into the groove on the surface of the plug rod 17 to engage the plug rod 17 inside the connecting sleeve 13, connecting the two sets of auxiliary airbags 4 to form a ring with the main airbag 2. The person falling into the water can place it under their armpit. After the life-saving device is used, place the device outside the arc plate 3, turn on the drive motor 11, and the drive motor 11 drives the rotating arm 8 to rotate through the drive shaft 10. The rotating arm 8 drives the linkage arm 6 to move through the linkage shaft 7. Under the sliding cooperation of the linkage rod 5 and the limiting groove 9, the linkage arm 6 drives the linkage rod 5 to slide inside the limiting groove 9. The three sets of linkage rods 5 synchronously drive the three sets of arc plates 3 to move outward. The arc plates 3 contact the inner ring surface of the life-saving device, and under the continuous action of the drive motor 11, the arc plates 3 fix the device, thus completing the placement of the life-saving device. The above is the complete usage of the marine life-saving device.
