Description

Technical Field

[0001] The invention relates to the technical field of water rescue, in particular to a portable ejection lifebuoy gun for water rescue. Background Art

[0002] As we all know, in the field of water rescue, the lifebuoy ejection device plays a vital role in the rapid and accurate rescue of people who fall into the water.

[0003] However, traditional water rescue ejection lifebuoy guns mostly use a single ejection power mechanism, such as relying solely on spring ejection or air pressure ejection, which has certain limitations; its ejection force and speed are difficult to flexibly adjust within a wide range, resulting in the ejection distance of the lifebuoy being limited, making it difficult to adapt to the rescue needs of people who fall into the water at different distances.

[0004] In addition, the ejection direction of most existing lifebuoy guns is fixed or can only be adjusted roughly manually. In actual rescue scenarios, the relative positions and angles between rescuers and drowning people are complex and changeable. Due to factors such as water flow, wind direction, and the position restrictions of rescue ships or shores, lifebuoys may need to be ejected from various angles. The inconvenient ejection direction of existing devices greatly reduces the accuracy and effectiveness of rescue, and often requires rescuers to spend extra time adjusting their own positions or multiple ejection attempts. The best rescue time may be delayed during water rescue operations, posing a serious threat to the life safety of drowning people.

[0005] Therefore, there is an urgent need for a new type of portable ejection lifebuoy gun for water rescue to solve the deficiencies of the prior art in ejection power and direction adjustment and to improve the efficiency and success rate of water rescue. Summary of the invention

[0013] As a further configuration of the present invention, the steering adjustment mechanism includes a partition fixedly installed in the lifebuoy placement cavity, on which a first motor is fixedly installed, and the output end of the first motor rotates through the top of the water rescue equipment body and is fixedly connected to the bottom center of the turntable.

[0015] As a further configuration of the present invention, the elevation adjustment mechanism includes an adjustment slot arranged on the left side of the top of the turntable, a rotating frame is also fixedly installed at the top center of the turntable, and the bottom of the ejection platform is rotatably installed on the rotating frame; the left side of the bottom of the ejection platform is also rotatably connected to a rotating support rod arranged obliquely, the bottom end of the rotating support rod is rotatably connected to a slide seat, and the slide seat is slidably installed in the adjustment slot along the horizontal direction; a lead screw is rotatably installed in the adjustment slot, a lead screw nut is fixedly installed on the slide seat, and the lead screw is also threadedly connected to the lead screw nut, an installation slot is provided on the right side of the adjustment slot, a second motor is fixedly installed in the installation slot, and the output end of the second motor is fixedly connected to the right end of the lead screw.

[0016] As a further configuration of the present invention, a plurality of ejection rollers arranged side by side are rotatably mounted in the ejection groove, and the bottom of the main life buoy is placed on the ejection rollers.

[0017] As a further configuration of the present invention, a universal wheel is arranged on the bottom side of the water rescue equipment body, a controller is arranged on the front side of the water rescue equipment body, and the controller is electrically controlled and connected with the electric cylinder, the first motor, the second motor, and the electric air pump respectively.

[0018] The beneficial effects of the present invention are:

[0019] 1. In the present invention, the push head, the push plate, the movable connecting rod and the push ring are quickly pushed by the electric cylinder, and then the main life buoy is pushed out from the ejection groove by the push ring, and there is also elastic force at the end of the push ring as a power to assist the ejection, so as to further eject the main life buoy, so that the main life buoy can be ejected to the water area to be rescued at a longer distance, so as to be used for the rescue of the rescued persons.

[0020] 2. In the present invention, during the contact process between the push ring and the main life buoy, since the main life buoy is limited, the push ring will be pushed back by the limit of the main life buoy. When the push ring is limited, the first ejection spring will be compressed. At the same time, when the push ring is limited, the end block will be driven to move left through the movable connecting rod and the second ejection spring will be stretched and deformed. In this way, when the electric cylinder further pushes the end of the push ring and contacts the main life buoy, once the limit elastic force of the first limit elastic strip and the second limit elastic strip is exceeded, the main life buoy will be further urged to make the first ejection spring The limiting elastic strip and the second limiting elastic strip are elastically deformed to the right and lose their limit, and finally the main life buoy is pushed out to the right. At the same time, the elastic reaction of the first ejection spring and the second ejection spring can further increase the pushing speed of the main life buoy to the right through the elastic force of the spring, thereby achieving the effect of "air refueling" of elastic pushing. In this way, the spring force can supplement additional energy on the basis of the thrust of the electric cylinder, extend the flight distance of the main life buoy, thereby further improving its effect of reaching the position of the person who fell into the water, and ensuring better overall use effect.

[0021] 3. In the present invention, during the ejection process of the main life buoy, the electric air pump can also be used to assist the ejection blowing head with air pressure to blow air to the right to enable the air pressure to eject the main life buoy. In this way, in addition to the traditional elastic ejection, the air pressure power is introduced to assist the ejection. In this way, the air pressure and elastic force can act simultaneously during the ejection, which can further increase the ejection power.

[0022] 4. In the present invention, the above-mentioned composite power method can also be flexibly adjusted according to the actual rescue scene. For example, when a longer distance ejection is required, the proportion of air pressure power is increased, and vice versa, the proportion of air pressure power is reduced. Finally, the air pressure can be further pushed, so that the ejection lifebuoy can be better played in the water rescue operation, avoiding the limitations of the existing water rescue ejection lifebuoy gun due to the use of a single ejection structure, greatly improving the ejection force and speed, making it more flexible in ejection use, which is conducive to adapting to the rescue needs of people who fall into the water at different distances.

[0023] 5. In the present invention, the ejection angle range can also be adjusted during rescue, not only the ejection angle of the main life buoy in the ejection groove can be adjusted along the rotation direction; at the same time, the elevation angle of the ejection of the ejection platform and the ejection groove can be adjusted, and the adjustment of the ejection elevation angle and the adjustment of the ejection angle along the circumferential rotation can be adjusted and coordinated at the same time, so that the ejection direction of the entire life buoy gun can be arbitrarily adjusted according to actual needs, avoiding the situation that the ejection direction of the existing life buoy gun is fixed or can only be roughly adjusted by limited manual operation, thereby failing to meet the requirements of ejecting life buoys at different angles.

[0024] In summary, the present invention pushes out the lifebuoy by quickly pushing the push ring through the electric cylinder, and the elastic force of the spring and the air pressure pushing force are provided at the end of the push ring for aerial refueling to further eject the lifebuoy. In this way, the air pressure and elastic force can further increase the speed of the lifebuoy, and achieve an effect similar to "aerial refueling", so that on the basis of the thrust of the electric cylinder, additional energy can be supplemented to extend the flight distance of the lifebuoy and increase the distance it reaches the position of the drowning person; through this two-stage ejection method, the advantages of both can be combined, the electric cylinder provides a stable and controllable initial power, the spring elastic force and the air pressure pushing provide subsequent explosive force, so that the lifebuoy plays an active and effective role in the entire ejection process; at the same time, by adjusting the ejection direction, the accuracy and scope of application of the rescue are greatly improved, and it can also avoid the situation in the past where rescuers need to spend extra time to adjust their own positions or multiple ejection attempts, which may delay the best rescue time, thereby posing a serious threat to the life safety of the drowning person, ensuring that the final use effect is better and suitable for popularization and use.

[0037] like Figure 4-5 In the figure, the ejection assist mechanism also includes a plurality of air pressure-assisted ejection blowing heads 141 fixedly mounted on the push plate 502 for further assisting the ejection of the main lifebuoy 7. An electric air pump 14 is fixedly mounted on the left side of the push plate 502, and the output end of the electric air pump 14 is connected to the air pressure-assisted ejection blowing head 141.

[0038] like Figure 6 In the embodiment, a plurality of air pressure assisted ejection blowing heads 141 are evenly arranged in a ring shape on the push plate 502 so as to evenly provide air pressure driving force to the main life buoy 7 .

[0039] like Figure 2-3 In the figure, the steering adjustment mechanism includes a partition 100 fixedly installed in the lifebuoy placement cavity 101, and a first motor 103 is fixedly installed on the partition 100. The output end of the first motor 103 rotates to penetrate the top of the water rescue equipment body 1 and is fixedly connected to the bottom center of the turntable 2.

[0040] like Figure 3 In the figure, a plurality of rolling seats 13 are evenly arranged in a ring shape on the bottom edge of the turntable 2, and a supporting ball 131 is rollingly installed on the bottom of the rolling seat 13. An annular rolling groove 132 is provided on the top side of the water rescue equipment body 1, and the bottom of the supporting ball 131 rolls in the annular rolling groove 132 along a circular track.

[0041] like Figure 3 In the figure, the elevation adjustment mechanism includes an adjustment slot 201 arranged on the left side of the top of the turntable 2, a rotating frame 3 is also fixedly installed at the top center of the turntable 2, and the bottom of the ejection platform 4 is rotatably installed on the rotating frame 3; the left side of the bottom of the ejection platform 4 is also rotatably connected with an inclined rotating support rod 10, the bottom end of the rotating support rod 10 is rotatably connected with a slide 205, and the slide 205 is slidably installed in the adjustment slot 201 along the horizontal direction; a screw rod 203 is rotatably installed in the adjustment slot 201, a screw rod nut 204 is fixedly installed on the slide 205, and the screw rod 203 is also threadedly connected with the screw rod nut 204, and an installation slot is provided on the right side of the adjustment slot 201, a second motor 202 is fixedly installed in the installation slot, and the output end of the second motor 202 is fixedly connected to the right end of the screw rod 203.

[0042] like Figure 3-4 In the ejection groove 401 , a plurality of ejection rollers 402 arranged side by side are rotatably installed, and the bottom of the main life buoy 7 is placed on the ejection rollers 402 .

[0043] Among them, a universal wheel 102 is arranged on the bottom side of the water rescue equipment body 1, and a controller 9 is arranged on the front side of the water rescue equipment body 1, and the controller 9 is electrically controlled and connected with the electric cylinder 5, the first motor 103, the second motor 202, and the electric air pump 14 respectively.

[0044] like Figure 1-6As shown, the portable ejection life buoy gun for water rescue, when in use: the electric cylinder 5 quickly pushes the push head 501, the push plate 502, the movable connecting rod 503 and the push ring 5, and then the main life buoy 7 is pushed out from the ejection groove 401 through the push ring 5, and there is also elastic force at the end of the push ring 5 as a power to perform auxiliary ejection, so as to further eject the main life buoy 7, so that the main life buoy 7 can be ejected to the water area to be rescued at a farther distance, so as to be used for the rescue of the rescued person. That is, during ejection: when the main lifebuoy 7 is pushed by the electric cylinder 5 to push the push ring 6 and contact the main lifebuoy 7, the main lifebuoy 7 will be elastically limited by the first limit elastic strip 11 and the second limit elastic strip 12. At the same time, during the contact process of the push ring 6 with the main lifebuoy 7, since the main lifebuoy 7 is limited, the push ring 6 will be limited by the reverse push of the main lifebuoy 7. When the push ring 6 is limited, the first ejection spring 504 will be compressed. At the same time, when the push ring 6 is limited, the end block 506 will be driven to move left through the movable connecting rod 503 and stretch the second ejection spring 505. In this way, when the electric cylinder 5 further pushes the end of the push ring 6 and contacts the main lifebuoy 7, once the first limit is exceeded, the push ring 6 will be pushed back. After the limiting elastic force of the elastic strip 11 and the second limiting elastic strip 12 is exerted, it will further prompt the main lifebuoy 7 to make the first limiting elastic strip 11 and the second limiting elastic strip 12 elastically deform to the right and lose the limit, and finally the main lifebuoy 7 is pushed to the right. At the same time, the elastic reaction of the first ejection spring 504 and the second ejection spring 505 can further increase the pushing speed of the main lifebuoy 7 to the right through the elastic force of the spring, thereby achieving the effect of "air refueling" of elastic pushing. In this way, the spring force can supplement additional energy on the basis of the thrust of the electric cylinder 5, extend the flight distance of the main lifebuoy 7, thereby further improving its effect of reaching the position of the person who falls into the water, and ensuring a better overall use effect.

[0045] At the same time, during the ejection process of the main life buoy 7, the electric air pump 14 can also be used to work and use the air pressure auxiliary ejection blowing head 141 to blow air to the right to make the air pressure push the main life buoy 7. In this way, in addition to the traditional elastic ejection, the air pressure power is introduced to assist the ejection, so that the air pressure and elastic force can act simultaneously during the ejection, which can further increase the power of the ejection. In addition, this composite power method can also be flexibly adjusted and used according to the actual rescue scene. For example, when a longer distance ejection is required, the proportion of air pressure power is increased, and vice versa, the proportion of air pressure power is reduced. Finally, the air pressure can be further pushed, so that the ejection life buoy can be better played in the water rescue operation, avoiding the limitations of the existing existing water rescue ejection life buoy gun due to the use of a single ejection structure, greatly improving the ejection force and speed, making it more flexible in ejection use, and conducive to adapting to the rescue needs of people falling into the water at different distances.

[0046] like Figure 3 As a further improvement, the ejection angle range can also be adjusted during rescue, that is, during adjustment: the output end of the first motor 103 drives the turntable 2 to rotate, and the turntable 2 drives the rotating frame 3, the ejection platform 4 and the position of the ejection groove 401 to rotate, so that the ejection angle of the main lifebuoy 7 in the ejection groove 401 can be adjusted along the rotation direction; at the same time, the second motor 202 can also drive the screw rod 203 forward and reverse, so that the slide 205 is threaded on the screw rod 203 through the screw nut 204, and the slide 205 is rotated left and right. During the movement, the ejection platform 4 can be driven to swing left or right based on the rotating frame 3 by rotating the support rod 10, so that the ejection elevation angle of the ejection platform 4 and the ejection groove 401 can be adjusted, and the ejection elevation angle adjustment and the ejection angle rotation adjustment along the circumference can be adjusted and coordinated at the same time, so that the ejection direction of the entire lifebuoy gun can be arbitrarily adjusted according to actual needs, avoiding the situation that the ejection direction of the existing lifebuoy gun is fixed or can only be roughly adjusted by limited manual operation, and thus it is difficult to meet the requirements of ejection of lifebuoys at different angles. Finally, by adjusting the ejection direction, the accuracy and scope of application of the rescue are greatly improved, and it can also avoid the situation that the rescue personnel need to spend extra time to adjust their own position or multiple ejection attempts in the past, which may delay the best rescue time, thereby posing a serious threat to the life safety of the drowning person; in addition, by placing multiple spare lifebuoys 701 in the lifebuoy placement cavity 101, it can be used to reserve more emergency rescue needs, ensuring that the final use effect is better and suitable for promotion and use.

[0047] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
