[0001] This invention relates to the field of rescue equipment technology, and in particular to river crossing and lifting rescue equipment. Background Technology

[0002] Among the existing water rescue equipment, commonly used rescue methods include manually throwing lifebuoys, using rope traction, or pneumatic launchers.

[0003] However, traditional equipment has many shortcomings in practical applications: On the one hand, most of the rope retrieval mechanisms are fixed structures, which cannot adjust the direction of the rope according to the site environment, resulting in poor rope release or difficulty in retrieval; On the other hand, the rescue module and lifebuoy have a single fixing method, which is difficult to adapt to lifebuoys of different sizes, and the deployment is not timely after falling into the water, which affects the grip of the person falling into the water. In addition, the air pressure control of the pneumatic launcher is unstable, making it difficult to achieve accurate launch, and it lacks an automatic recovery function. Rescuers need to manually pull back the rope, which is time-consuming, laborious, and poses secondary risks.

[0023] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0024] like Figures 1 to 6 As shown, the river crossing and rescue equipment includes a drive cylinder 1, with a jetting annular cylinder 2 fixedly connected to the front end of the drive cylinder 1, and a rescue module 3 provided at the front end of the jetting annular cylinder 2.

[0025] Specifically, such as Figure 2 and Figure 6 As shown, a high-pressure gas tank 11 is fixedly installed at the rear end of the inner cavity of the drive cylinder 1. A wire take-up mechanism 13 is provided on the front side of the high-pressure gas tank 11. An air supply pipe 12 is fixedly connected to the output end of the high-pressure gas tank 11. The air supply pipe 12 passes over the top of the wire take-up mechanism 13 and extends to communicate with the jet annular cylinder 2. The air supply pipe 12 is used to transport the high-pressure gas in the high-pressure gas tank 11 to the jet annular cylinder 2 to provide air pressure to eject the rescue module 3.

[0026] like Figure 2 , Figure 3 and Figure 5 As shown, the take-up mechanism 13 includes a C-shaped plate 131, a servo motor 132, and a take-up roller 133. The servo motor 132 is fixedly mounted on the side of the C-shaped plate 131. The take-up roller 133 is rotatably mounted between the two horizontal ends of the C-shaped plate 131 and is fixedly connected to the output shaft of the servo motor 132, which drives its rotation. A rescue rope 138 is wound around the take-up roller 133. One end of the rescue rope 138 passes through the jet annular cylinder 2 and is connected to the rescue module 3 for retrieving the rescue module 3 during take-up. A telescopic rod 137 is rotatably connected to the bottom of the C-shaped plate 131. The bottom end of the telescopic rod 137 is fixedly mounted to the bottom of the inner cavity of the drive cylinder 1. The top of the C-shaped plate 131 is fixedly mounted on the bottom of the drive cylinder 1. A lifting rod 134 is fixedly installed, and a limiting plate 135 is fixedly installed on the top of the lifting rod 134. A lifting handle 136 is fixedly installed on the top of the limiting plate 135. A cross-shaped limiting through hole 14 adapted to the limiting plate 135 is opened on the top of the drive cylinder 1. The operator can lift upward by lifting the handle 136, so that the limiting plate 135 passes through the cross-shaped limiting through hole 14 and extends out of the top of the drive cylinder 1. Then, the lifting rod 134 is rotated, which drives the C-shaped plate 131 and the winding roller 133 to rotate, thereby changing the orientation of the winding roller 133. When the limiting plate 135 rotates 90 degrees and is locked into the cross-shaped limiting through hole 14 again, the end of the winding roller 133 away from the servo motor 132 faces the spray annular cylinder 2, which facilitates the rapid release of the rescue rope 138.

[0027] like Figure 3 and Figure 4As shown, the rescue module 3 includes an umbrella-shaped hollow tube 31 and a lifebuoy 33 fitted onto its front side. An annular retainer 32 is fixedly installed on the rear side of the umbrella-shaped hollow tube 31. The annular retainer 32 is used to engage with the annular outlet at the front end of the jet annular tube 2, so that the rescue module 3 is fixed to the front end of the jet annular tube 2 before launch. The rescue rope 138 passes through the line release channel 21 and is fixedly connected to the center of the umbrella-shaped hollow tube 31. This connection point is located on the inner ring of the annular retainer 32. The front end of the umbrella-shaped hollow cylinder 31 is fixedly equipped with a number of lifebuoy positioning straps 311 in an annular array, and the rear end outer wall is fixedly equipped with a number of male snap fasteners 313 in an annular array. The other end of the lifebuoy positioning straps 311 is fixedly equipped with a female snap fastener 312. The female snap fastener 312 and the male snap fastener 313 are fastened together to position and fix the lifebuoy 33 on the outer wall of the umbrella-shaped hollow cylinder 31. The tapered structure design of the front end of the umbrella-shaped hollow cylinder 31 allows it to adapt to lifebuoys 33 of different sizes.

[0028] like Figure 2 and Figure 6 As shown, a pulse valve 121 and a pressure regulating valve 122 are provided on the air supply pipe 12. The pressure regulating valve 122 is connected to the output end of the high-pressure gas tank 11 to stabilize the output gas pressure. The pulse valve 121 generates pulse gas by rapidly opening and closing the high-pressure gas source. The pulse gas enters the annular inner cavity of the injection annular cylinder 2 through the air supply pipe 12, thereby ejecting the annular sleeve 32 stuck at its front end together with the umbrella-shaped hollow cylinder 31. A handle 15 is fixedly installed on the outer wall of the drive cylinder 1. A pulse valve control button 151 is provided on the handle 15. The pulse valve control button 151 is electrically connected to the pulse valve 121 and is used to control the opening and closing of the pulse valve 121.

[0029] like Figure 6 As shown, a pressure gauge 111 is fixedly installed on the outer wall of the high-pressure gas tank 11, penetrating to the outer wall of the drive cylinder 1, for displaying the remaining gas volume in the high-pressure gas tank 11 in real time. An air inlet 112 is fixedly connected to the rear side of the high-pressure gas tank 11, penetrating to the rear side of the drive cylinder 1, for replenishing gas into the high-pressure gas tank 11.

[0030] like Figure 1 and Figure 2 As shown, the front end of the spray annular cylinder 2 forms a through-channel 21, and the rear end of the through-channel 21 is connected to the inner cavity of the drive cylinder 1. After the rescue rope 138 is led out from the take-up roller 133, it passes through the through-channel 21 and extends to the front side of the spray annular cylinder 2 to connect with the rescue module 3.

[0031] In addition, a shoulder strap is fixedly installed on the outer wall of the drive cylinder 1 for easy carrying. The inner cavity of the drive cylinder 1 is provided with a battery that is electrically connected to the servo motor 132 and the pulse valve 121 to provide power to various electronic devices.

[0032] The working principle of this river crossing and rescue equipment will be explained in detail below.

[0033] like Figure 1-6 As shown, in the initial state, the rescue module 3 is engaged with the annular outlet at the front end of the jet annular cylinder 2 via its annular sleeve 32. The lifebuoy 33 is fixed to the umbrella-shaped hollow cylinder 31 by the lifebuoy positioning strap 311 and the cooperation of the female snap buckle 312 and the male snap buckle 313. One end of the rescue rope 138 is connected to the umbrella-shaped hollow cylinder 31, and the other end is wound around the take-up roller 133. When a rescue is needed, the operator presses the pulse valve control button 151, and the pulse valve 121 opens instantly. The high-pressure gas in the high-pressure gas tank 11 is stabilized by the pressure regulator 122 and then forms a pulse airflow through the pulse valve 121. This pulse airflow enters the jet annular cylinder 2 through the air supply pipe 12, rapidly propelling the rescue module 3 forward. After the rescue module 3 falls into the water, the lifebuoy 33 unfolds, allowing the rescuer to grab it or put it on their body. When it is necessary to retrieve the rescue module 3 or the rescuer... At this time, the operator first pulls the take-up mechanism 13 upward by pulling the handle 136, so that the limiting plate 135 is disengaged from the cross-shaped limiting through hole 14. Then, the operator rotates the lifting rod 134 about 90 degrees, so that the limiting plate 135 is aligned with the slot in the other direction of the cross-shaped limiting through hole 14 and then lowers it, so that the limiting plate 135 is re-engaged into the cross-shaped limiting through hole 14. At this time, the axial direction of the take-up roller 133 is consistent with the axial direction of the drive cylinder 1, and the end of the take-up roller 133 away from the servo motor 132 faces the spray annular cylinder 2. Then, the servo motor 132 is started to drive the take-up roller 133 to rotate and start to take up the rescue rope 138. During the take-up process, the rescue rope 138 is gradually pulled back until the annular sleeve 32 at the rear end of the umbrella-shaped hollow cylinder 31 is once again engaged in the annular outlet at the front end of the spray annular cylinder 2, and the retrieval is completed.
