Quickly deployable sea surface personnel life-saving net

Abstract

This utility model relates to the field of marine rescue equipment technology, and in particular to a rapidly deployable sea rescue net. This utility model provides such a rapidly deployable sea rescue net, including a fixed base, a support shell, a servo motor, and a connecting plate. The support shell is fixedly connected to the bottom of the fixed base, and the servo motor is installed at the bottom of the support shell. The connecting plate is connected to the output shaft of the servo motor. The servo motor drives the connecting plate to rotate, causing a slider to slide on a guide rail. This, through a diamond-shaped sleeve, moves the connecting base, support base, and support tube on both sides away from each other, thereby rapidly deploying the rescue net. This solves the problem that existing marine rescue equipment often requires manual deployment, which is slow and easily affected by environmental factors such as sea waves, resulting in the inability to deploy the rescue net in time to cover the person in the water, thus delaying the best rescue opportunity.

Description

Technical Field

[0001] This utility model relates to the field of marine rescue equipment technology, and in particular to a rapidly deployable sea surface rescue net. Background Technology

[0002] A maritime rescue net is a tool specifically designed for rescuing people in a maritime environment. It is usually made of a specific material, possessing a certain strength and toughness, capable of supporting the weight of a person and floating on the sea surface. In emergency situations such as people falling into the water, the rescue net can be deployed near the person in the water, allowing them to cling to it or lie on it, thus ensuring their safety while awaiting further rescue. Therefore, in maritime rescue scenarios, it is crucial to rescue people in the water quickly and effectively.

[0003] Although existing sea rescue equipment is widely used in maritime rescue, it still has some shortcomings and limitations. For example, existing sea rescue equipment often requires manual deployment of the rescue net, which is slow and easily affected by environmental factors such as wind and waves, making it impossible to deploy the rescue net in time and cover the person in the water, thus delaying the best rescue opportunity.

[0004] Therefore, it is necessary to design a sea rescue net that can be deployed quickly. Utility Model Content

[0005] To overcome the shortcomings of existing marine rescue equipment, which often requires manual deployment of the rescue net, is slow in deployment, and is easily affected by environmental factors such as sea waves, resulting in the inability to deploy the rescue net in time and cover the area around the person in the water, thus delaying the best rescue opportunity, this utility model provides a marine personnel rescue net that can be deployed quickly.

[0006] The technical implementation scheme of this utility model is as follows: a rapidly deployable sea rescue net, comprising a rescue net body, a support tube, a support base, a connecting base one, a diamond-shaped sleeve, a diamond-shaped rod, a connecting cylinder, a limiting seat, a fixed base, a support shell, a servo motor, a connecting plate, a connecting base two, a guide rail, and a slider. The supporting shell is fixedly connected to the bottom of the fixed base, and a servo motor is installed at the bottom of the supporting shell. A connecting plate is connected to the output shaft of the servo motor, and sliders symmetrically distributed on the left and right sides are fixedly connected inside the connecting plate. A limiting seat is fixedly connected to the bottom of the fixed base. The lower end of the limiting seat is rotatably connected to a connecting cylinder. A rhomboid rod is fixedly connected inside the connecting cylinder. The rhomboid rod passes through the connecting cylinder. Rhomboid sleeves are slidably connected to the outer sides of the left and right sides of the rhomboid rod. Connecting seat two is rotatably connected to the side of the two rhomboid sleeves that are far apart from each other. A guide rail is fixedly connected to the top of each connecting seat two. The slider is slidably connected to the guide rail. Connecting seat one is fixedly connected to each rhomboid sleeve. Support seats are fixedly connected between the front and rear sides of the lower end of the connecting seat. Support tubes are connected to each support seat. The life net body is connected between the two support tubes.

[0007] More preferably, it also includes a hanging ring, with the hanging ring fixedly connected to the top of the fixing base.

[0008] More preferably, it also includes a worm wheel, a drive motor, and a worm. The worm wheel is fixedly connected to the connecting cylinder, the drive motor is installed on the rear side of the limit seat, and the worm is connected to the output shaft of the drive motor. The worm wheel and the worm mesh with each other.

[0009] More preferably, it also includes a limiting shaft and a baffle, with the limiting shaft fixedly connected to both the front and rear sides of the support base, and a baffle slidably connected between the front and rear sides of the support base on the same side, with the support base and the baffle slidably connected.

[0010] More preferably, the guide rail has a T-slot structure.

[0011] Even more preferably, the hanging ring is made of stainless steel.

[0012] Beneficial effects: 1. The servo motor drives the connecting plate to rotate, causing the slider to slide on the guide rail. This causes the connecting seats, support seats, and support tubes on both sides to move away from each other through the diamond sleeve, thereby quickly unfolding the lifenet body. This solves the problem that existing sea rescue equipment often requires manual unfolding of the lifenet, which is slow and easily affected by environmental factors such as sea waves, resulting in the inability to unfold the lifenet in time and cover the area around the person in the water, thus delaying the best rescue opportunity.

[0013] 2. This utility model, by setting up a worm gear, a drive motor and a worm, starts the drive motor, and its output shaft rotates to drive the worm to rotate, thereby driving the worm to rotate, which in turn drives the rhomboid rod to rotate through the connecting sleeve. The rotation of the rhomboid rod is transmitted to the connecting seat, the support seat and the support tube through the rhomboid sleeve, and finally realizes the angle adjustment of the rescue net body, which makes it easy to quickly retrieve the person to be rescued onto the rescue net body.

[0020] Example: A rapidly deployable sea rescue net, such as... Figures 1-5 As shown, the lifeline includes a lifeline body 1, a support tube 2, a support base 3, a connecting base 1 4, a diamond-shaped sleeve 5, a diamond-shaped rod 6, a connecting cylinder 7, a limiting seat 8, a fixing seat 9, a hanging ring 10, a support shell 11, a servo motor 12, a connecting plate 13, a connecting base 2 14, a guide rail 15, and a slider 16. A hanging ring 10 is welded to the top of the fixing base 9. The hanging ring 10 is made of stainless steel and has excellent tensile strength and seawater corrosion resistance. A support shell 11 is welded to the bottom of the fixing base 9. A servo motor 12 is installed inside the bottom of the support shell 11. A connecting plate 13 is connected to the output shaft of the servo motor 12. Slider 16, symmetrically distributed on both sides, are welded inside the connecting plate 13. A limiting seat 8 is welded to the bottom of the fixed seat 9. A connecting cylinder 7 is rotatably connected to the lower end of the limiting seat 8. A rhomboid rod 6 is welded inside the connecting cylinder 7. The rhomboid rod 6 passes through the connecting cylinder 7. Rhomboid sleeves 5 are slidably connected to the outer sides of the left and right sides of the rhomboid rod 6. A connecting seat 2 14 is rotatably connected to the side of the two rhomboid sleeves 5 that is far apart from each other. A guide rail 15 is welded to the top of the connecting seat 2 14. The guide rail 15 has a T-slot structure. The slider 16 is slidably connected to the guide rail 15. A connecting seat 1 4 is welded to the rhomboid sleeve 5. A support seat 3 is welded between the front and rear sides of the lower end of the connecting seat 1 4. A support tube 2 is connected to the support seat 3. The life net body 1 is connected between the two support tubes 2.

[0021] like Figure 4 and Figure 5 As shown, it also includes a worm gear 17, a drive motor 18, and a worm 19. The worm gear 17 is welded onto the connecting cylinder 7, and the drive motor 18 is installed on the rear side of the limiting seat 8. The worm 19 is connected to the output shaft of the drive motor 18. The worm gear 17 and the worm 19 mesh with each other, which can realize the angle adjustment of the life net body 1.

[0022] like Figure 2 and Figure 3As shown, it also includes a limiting shaft 20 and a baffle 21. The limiting shaft 20 is welded to both the front and rear sides of the support base 3. The baffle 21 is slidably connected between the front and rear sides of the support base 3 on the same side. The support base 3 and the baffle 21 are slidably connected. The baffle 21 can prevent the rescued person from falling back into the sea and ensure the reliability of the rescue process.

[0023] In its initial state, this device is suspended from rescue boats, cranes, and other rescue equipment via the hanging ring 10. The connecting plate 13 is diagonally positioned on both sides, and the lifenet body 1 is a pocket-shaped structure with a central concave depression. When a person is found to have fallen into the sea and needs to be rescued, the servo motor 12 is activated. The output shaft of the servo motor 12 rotates, causing the connecting plate 13 to rotate. The rotation of the connecting plate 13 causes the slider 16 to slide on the guide rail 15, thereby driving the two rhomboid sleeves 5 to slide away from each other on the rhomboid rod 6 via the connecting seat 2 14. At this time, the rhomboid sleeves 5 slide away from each other. The motor drives the connecting seats 4, support seats 3, and support tubes 2 on both sides to move away from each other. At this time, the limit shaft 20 slides on the baffle 21 until the left and right sides of the connecting plate 13 are symmetrical. Then the servo motor 12 is turned off, thereby quickly unfolding the rescue net body 1 and expanding the rescue range. Then the drive motor 18 is started, and its output shaft rotates to drive the worm gear 19 to rotate. Since the worm wheel 17 and the worm gear 19 are meshed, the rotation of the worm wheel 17 drives the worm gear 19 to rotate, which in turn drives the rhomboid rod 6 to rotate through the connecting cylinder 7. The rotation of the rhomboid rod 6 drives the rhomboid rod 6 to rotate through the rhomboid... Sleeve 5 transmits rotational power to connecting seat 4, support seat 3, and support pipe 2, ultimately adjusting the angle of the rescue net body 1. This facilitates the rapid retrieval of the person to be rescued onto the rescue net body 1. The rescue net body 1 is then slowly lowered to the vicinity of the person in the water by a crane for retrieval. After retrieval, the output shaft of drive motor 18 is reversed, causing connecting seat 4, support seat 3, and support pipe 2 to return to a vertical position. This allows the person to lie flat on the rescue net body 1, and baffle 21 closes the front and rear sides to prevent further injury. If the rescuer falls back into the sea, ensuring the reliability of the rescue process, the rescue net body 1 is then smoothly lifted onto the ship's deck by a crane, thus completing the rescue process. The output shaft of the servo motor 12 can be controlled to rotate in reverse, and the slider 16 is slid and reset on the guide rail 15 through the connecting plate 13. This causes the two rhomboid sleeves 5 to slide closer to each other on the rhomboid rod 6 through the connecting seat 2 14, so that the connecting seat 1 4, the support seat 3 and the support tube 2 also move closer to each other, allowing the rescue net body 1 to be quickly retracted, saving space for the next use.
