Description

Technical Field

[0001] The present invention relates to the technical field of rescue equipment, and in particular to a rescue ejection device for a water rescue boat. Background Art

[0002] A throw-type life revive is a new type of water accident rescue equipment. Its structure generally includes a catapult device and a self-inflating life buoy. When in use, the self-inflating life buoy is loaded into the catapult device for launch, and then the self-inflating life buoy is inflated to rescue the drowning person.

[0003] In the actual rescue process, in order to prevent the launched self-inflating life buoy from hitting the drowning person when falling, the self-inflating life buoy is generally launched within a certain distance around the drowning person, and because the self-inflating life buoy will be affected by the inertia of the launch after launching, it will inevitably drift and slide on the water for a distance. Therefore, most of the current methods use the inertia of the self-inflating life buoy after launching to drift to the drowning person to achieve the rescue of the drowning person. However, the self-inflating life buoy is easily affected by the water flow, wind force, etc. after entering the water, resulting in the self-inflating life buoy often unable to accurately and timely drift close to the drowning person, and it is easy to miss the best rescue time for the drowning person. Summary of the invention

[0004] The purpose of the present invention is to overcome the above-mentioned deficiencies of the prior art and to provide a rescue ejection device for a water rescue boat.

[0005] In order to achieve the above object, the present invention adopts the following technical solution:

[0006] A rescue ejection device for a water rescue boat comprises an ejection tube and a rescue ball placed in the ejection tube, the rescue ball comprises a relatively buckled ball shell and a life buoy arranged in the ball shell, a guide plate and a convex plate slidably arranged in the guide plate are fixed on the ball shell, a through hole corresponding to the position of the convex plate is opened on the ball shell, an inflatable tank is arranged in the life buoy, the life buoy is inflated and presses the convex plate outwards.

[0007] Preferably, a stop plate is fixed on the convex plate, and a spring 2 is sleeved on the outer periphery of the convex plate, one end of the spring 2 being fixed to the stop plate, and the other end of the spring 2 is fixed to the guide plate.

[0008] Preferably, the gas filling tank is provided with chamber one for placing solid reactants and chamber two for placing liquid reactants, a diaphragm is provided between chamber one and chamber two, the gas filling tank is provided with an air hole connected to chamber one, and a scriber is placed in chamber one.

[0009] Preferably, an annular blade is provided at the periphery of the scriber, and the size of the annular blade is larger than the size of the pore.

[0010] Preferably, the ejection tube is arranged on a mounting plate, a sliding block sliding along the length direction of the ejection tube is provided on the mounting plate, an abutment plate extending into the ejection tube is rotatably provided on the sliding block, a spring is provided in the ejection tube, and the abutment plate presses the spring inwardly through the rescue ball.

[0011] Preferably, an ejection hole is provided at one end of the ejection tube, a notch is provided on a side wall of the ejection hole, and a roller is rotatably mounted on the ejection tube, one side of the roller extending into the notch.

[0012] Preferably, a side groove is provided on one side of the ejection tube, and the abutment plate extends into the side groove and abuts against the rescue ball.

[0013] Preferably, a fixing plate is mounted on the sliding block, the abutting plate is rotatably arranged on the fixing plate, and a limiting plate is slidably arranged on the sliding block, the limiting abutting plate being in contact with the fixing plate and abutting against the limiting abutting plate.

[0014] Preferably, a sliding hole matched with the limiting plate is provided on the sliding block, and the limiting plate passes through the sliding hole and can slide away from the abutting plate.

[0015] Preferably, one side of the mounting plate is connected to a cylinder for driving the mounting plate to rotate.

[0016] The beneficial effects of the present invention are:

[0017] 1. The life buoy is placed in the rescue ball. When the inflatable tank in the life buoy reacts to produce a large amount of gas, the life buoy is inflated to squeeze the convex plates out of the rescue ball. That is, after the rescue ball is launched and falls into the water, the convex plates on both sides contact the water surface to generate resistance, so as to quickly offset the inertial force of the rescue ball when it is launched, so that the launched rescue ball can drift around the drowning person more stably. As the life buoy is further inflated, the life buoy squeezes and expands the rescue ball, and is inflated to become a life buoy that can support and rescue the drowning person, thereby achieving rapid and reliable rescue of the drowning person, and improving the efficiency and success rate of water rescue operations.

[0018] 2. A roller is arranged at the ejection hole end of the ejection tube. When the rescue ball is launched from the ejection hole, it will roll in contact with the roller, so that the rescue ball can be rotated and launched. As the rescue ball rotates, the scriber in the inflation tank cuts the diaphragm, so that the solid reactant (such as sodium bicarbonate) in chamber one and the liquid reactant (such as acetic acid solution) in chamber two are mixed and reacted, and a large amount of carbon dioxide is generated to inflate the life buoy, thereby improving the reliability of the life buoy inflation rescue.

DETAILED DESCRIPTION

[0030] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments:

[0031] In the description of this specification, the directions or positional relationships indicated by the terms "up", "down", "left", "right", etc. are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or unit referred to must have a specific direction, be constructed and operated in a specific orientation. Therefore, it should not be understood as a limitation on the present invention.

[0032] like Figures 1 to 10As shown, a rescue ejection device for a water rescue boat comprises an ejection tube 2 and a rescue ball 4 placed in the ejection tube 2, wherein the ejection tube 2 is used to launch the rescue ball 4, and the number of the ejection tubes 2 is multiple, and the ejection tubes 2 are arranged on a mounting plate 1, and a cylinder 11 is connected to one side of the mounting plate 1 for driving the mounting plate 1 to rotate, and the other side of the mounting plate 1 is hinged and fixed, that is, the mounting plate 1 is driven to rotate by the cylinder 11 rising and falling to realize the adjustment of the launching angle of the ejection tube 2.

[0033] Furthermore, the mounting plate 1 is provided with a slider 12 and a drive motor 122 that slide along the length direction of the ejection tube 2, and a screw rod 123 is connected to the output end of the drive motor 122. The sliders 12 are multiple and are arranged at intervals on the screw rod 123. The sliders 12 are slidably arranged on the slide rail 13, and the slide rail 13 provides guidance for the reciprocating sliding of the slider 12.

[0034] The slider 12 is rotatably provided with an abutment plate 15 extending into the ejection tube 2, and a spring 3 is provided in the ejection tube 2. The spring 3 and the rescue ball 4 are arranged in the ejection tube 2 in a one-to-one correspondence. Specifically, a fixed plate 14 is installed on the slider 12, and the abutment plate 15 is rotatably provided on the fixed plate 14. A side groove 21 is provided on one side of the ejection tube 2. The abutment plate 15 extends into the side groove 21 and abuts against the rescue ball 4. There are multiple abutment plates 15 and they are arranged in a one-to-one correspondence with the rescue ball 4. The abutment plate 15 presses the spring 3 inwardly through the rescue ball 4, and then when the abutment plate 15 is away from the rescue ball 4, the rescue ball 4 can be launched by the elastic force of the spring 3.

[0035] refer to Figure 2 , Figure 3 , Figure 6 As shown, the mounting plate 1 is provided with a slide groove 17 for the fixed plate 14 to slide, and the slider 12 is slidably provided with a limit plate 16 that fits the fixed plate 14 and abuts against the limit abutment plate 15, and the limit plate 16 abuts against the abutment plate 15 to prevent the abutment plate 15 from rotating under the action of the spring 3.

[0036] The slider 12 is provided with a sliding hole 121 adapted to the limit plate 16, and the limit plate 16 passes through the sliding hole 121 and can slide away from the abutment plate 15. Specifically, the fixed plate 14 is installed with a cylinder 161, and the output end of the cylinder 161 is connected to the limit plate 16, so that the limit plate 16 is driven to slide downward through the cylinder 161, and then the abutment plate 15 can be separated from the abutment of the limit plate 16, so that the squeezed spring 13 can drive the rescue ball 4 to be launched under the action of its own elastic force, and as the rescue ball 4 is launched, the corresponding spring 13 also pops out of the ejection tube 2, so as to avoid the spring 13 interfering with the subsequent rescue ball 4 launching action.

[0037] Furthermore, multiple rescue balls 4 can be arranged in one ejection tube 2, and multiple rescue balls 4 can be saturatedly launched by cooperating with corresponding springs 1 3, that is, multiple rescue balls 4 are launched around the drowning person, which greatly improves the effect of the rescue balls 4 in rescuing the drowning person and ensures the reliability of water rescue operations.

[0038] In order to further ensure the reliability of the rescue operation, the rescue ball 4 includes a relatively buckled ball shell 41 and a lifebuoy 46 arranged in the ball shell 41. The lifebuoy 46 is arranged inside two buckled ball shells 41. A guide plate 42 and a convex plate 44 slidably arranged in the guide plate 42 are fixed on the ball shell 41. The number of the convex plates 44 is two and they are correspondingly distributed on the two ball shells 41. A through hole 43 corresponding to the position of the convex plate 44 is opened on the ball shell 41. The convex plate 44 can slide along the guide plate 42 and extend the rescue ball 4 outward through the through hole 43.

[0039] An inflatable tank 5 is arranged inside the life buoy 46. The life buoy 46 is inflated and presses the convex plate 44 outwards. The convex plate 44 is made of flexible rubber material to prevent the protruding convex plate 44 from hitting the drowning person and causing harm to the drowning person.

[0040] When the inflation tank 5 in the life buoy 46 reacts to produce a large amount of gas, the life buoy 46 inflates to squeeze the convex plates 44 outward to squeeze the rescue ball 4, that is, after the rescue ball 4 is launched and falls into the water, the convex plates 44 extending on both sides contact the water surface to generate resistance, so as to quickly offset the inertial force of the rescue ball 4 when it is launched, so that the launched rescue ball 4 can float relatively stably around the drowning person.

[0041] As the lifebuoy 46 is further inflated, the lifebuoy 46 squeezes and expands the spherical shell 41 of the rescue ball 4, and is inflated to become the lifebuoy 46 that can support and rescue the drowning person, so as to achieve rapid and reliable rescue of the drowning person, thereby avoiding the problem that the launched rescue ball 4 will drift and slide under the action of inertia, resulting in the inability to accurately control the falling point of the rescue ball 4, that is, the inability to accurately launch the lifebuoy 46 to the drowning person, resulting in untimely rescue and other problems. Therefore, the present embodiment can greatly improve the efficiency and success rate of water rescue operations by cooperating with the rescue ball 4 and the convex plate 44.

[0042] Furthermore, the gas filling tank 5 is provided with a chamber 1 51 for placing a solid reactant and a chamber 2 52 for placing a liquid reactant. The solid reactant may be sodium bicarbonate, and the liquid reactant may be an acetic acid solution. A diaphragm 53 is provided between the chamber 1 51 and the chamber 2 52, and the diaphragm 53 separates the chamber 1 51 from the chamber 2 52.

[0043] The inflation tank 5 is provided with an air hole 511 connected to the chamber 1 51, and a scriber 54 is placed in the chamber 1 51. Specifically, an annular blade 541 is provided on the outer periphery of the scriber 54, and the size of the annular blade 541 is larger than the size of the air hole 511 to prevent the annular blade 541 from cutting the lifebuoy 46 through the air hole 511.

[0044] The annular blade 541 cuts through the diaphragm 53 to mix and react the solid reactant in the chamber 1 51 and the liquid reactant in the chamber 2 52, and generates a large amount of carbon dioxide to inflate the lifebuoy 46 through the air hole 511. As the lifebuoy 46 is inflated, the convex plate 44 squeezes out the rescue ball 4, and as the lifebuoy 46 is further inflated, the lifebuoy 46 is inflated to a state where it can be rescued. Fig.10 shown.

[0045] A butt plate 441 is fixed to the convex plate 44, and a spring 2 45 is sleeved on the outer periphery of the convex plate 44, one end of which is fixed to the butt plate 441, and the other end of the spring 2 45 is fixed to the guide plate 42. At this time, through the setting of the spring 2 45, the convex plate 44 can maintain a state of extending into the rescue ball 4, and the butt plate 441 is abutted by the inflated life buoy 46, so that the convex plate 44 can extend out of the rescue ball 4, and when the convex plate 44 extends out of the rescue ball 4, the butt plate 441 abuts against the guide plate 42 to limit the extension of the convex plate 44.

[0046] In order to ensure the reliability of inflation of the lifebuoy 46, an ejection hole 22 is opened at one end of the ejection tube 2, and the rescue ball 4 is launched outward through the ejection hole 22. A notch 23 is opened on the side wall of the ejection hole 22. A roller 24 with one side extending into the notch 23 is rotatably installed on the ejection tube 2. An extension plate 25 for rotatably installing the roller 24 is fixed on the ejection tube 2, and the roller 24 is rotatably set on the extension plate 25.

[0047] When the rescue ball 4 is launched from the ejection hole 22, it will roll in contact with the roller 24, so that the rescue ball 4 can be rotated and launched, and as the rescue ball 4 rotates, the scriber 54 in the inflation tank 5 can more easily cut the diaphragm 53 to ensure that the solid reactant in chamber one 51 can mix and react with the liquid reactant in chamber two 52 to produce a large amount of carbon dioxide gas for inflation, thereby improving the reliability of inflation and rescue of the lifebuoy 46.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
