Description

Technical Field

[0001] The present invention relates to the technical field of water survival equipment, and particularly to a fire fighting water rescue device and its method. Background Art

[0002] Water fire fighting refers to the fire safety management, fire prevention and rescue activities specifically carried out for waters and water facilities. The main responsibilities include fire prevention and drowning prevention: enhancing the public's awareness of fire prevention and drowning prevention through publicity and education activities. Patrol and duty: Regularly patrol the waters to ensure the integrity of fire fighting facilities, and promptly discover and handle potential safety hazards. Emergency rescue: Respond quickly when a water accident occurs, carry out search and rescue tasks, and ensure the safety of people's lives and property.

[0003] Water fire fighting is a professional fire safety system specifically established for fires and emergency rescue situations in the water environment. The rescue devices used for drowning people mainly include life jackets, lifebuoys, life ropes, inflatable rubber rafts and rescue stretchers.

[0004] However, during the process of the water rescue stretcher moving to the side of the person to be rescued through the underwater thruster, waterweeds in the water are likely to be adsorbed on the surface of the underwater thruster, affecting the pushing speed of the underwater thruster, so that it cannot move to the side of the rescued person in time. Moreover, when using the rescue stretcher for rescue, the rescue personnel need to inflate the rescue stretcher in advance, resulting in extremely inconvenient use. At the same time, during the driving process of the water rescue stretcher, the water splashes will be splashed onto the imaging part of the imaging device of the water rescue stretcher, affecting the imaging effect. At this time, the rescue personnel controlling the driving of the water rescue stretcher cannot clearly understand the driving direction and position of the water rescue stretcher.

[0038] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following will make a detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings of the specification.

[0039] In the following description, many specific details are set forth to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0040] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that can be included in at least one implementation manner of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it an individual or alternative embodiment that is mutually exclusive with other embodiments.

[0041] Next, the present invention will be described in detail with reference to the schematic diagrams. When describing the embodiments of the present invention in detail, for the convenience of explanation, the cross-sectional views showing the device structure will be enlarged locally not in accordance with the general scale, and the schematic diagrams are only examples and should not limit the scope of protection of the present invention herein. In addition, in actual production, three-dimensional spatial dimensions including length, width, and depth should be included.

[0042] Embodiment 1

[0043] Referring to Figures 1 to 7 , for the first embodiment of the present invention, a rescue method for a fire fighting waterborne rescue device is provided. Through the rescue method of the fire fighting waterborne rescue device, the effects of timely inflation to reduce the interference caused by waterweeds and water splashes and auxiliary heating are achieved.

[0044] When it is necessary to rescue a drowning person in the water, control the stretcher rescue mechanism 100 to drive beside the drowning person and inflate at the same time, so as to facilitate the drowning person to climb onto the stretcher rescue mechanism 100. Inflating while driving can greatly improve the rescue efficiency and avoid the situation where the rescue efficiency is reduced due to rescuing after inflation.

[0045] During the driving process of the stretcher rescue mechanism 100, the anti-deceleration mechanism 200 will be activated to continuously scrape off the waterweeds or other foreign objects attached to the stretcher rescue mechanism 100, avoiding the situation where the speed of the stretcher rescue mechanism 100 is reduced due to the attachment of these waterweeds and foreign objects, resulting in the inability to rescue in time.

[0046] When the stretcher rescue mechanism 100 is driving relatively fast, the wiping mechanism 300 will be activated to continuously wipe the imaging area of the camera 107 on the stretcher rescue mechanism 100, improving the imaging clarity of the camera 107 and avoiding the situation where the rescue personnel cannot clearly observe the current position and direction of the stretcher rescue mechanism 100 during the driving process of the stretcher rescue mechanism 100.

[0047] When the drowning person climbs onto the stretcher rescue mechanism 100, the heating mechanism 400 can be activated to generate heat, thereby increasing the body temperature of the drowning person and avoiding the continuous loss of body temperature of the drowning person after climbing onto the stretcher rescue mechanism 100, which may affect the life and health of the drowning person.

[0048] Embodiment 2

[0049] Referring to Figure 1 , 7 , for the second embodiment of the present invention, the wiping mechanism 300 is provided. Through the wiping mechanism 300, the auxiliary wiping of water stains is achieved.

[0050] The wiping mechanism 300 includes a support member 301. One end of the support member 301 is fixedly connected to the top of the back surface of the connection plate 106. The other end of the support member 301 is movably connected to an inclined gear disk 302. The front side of the bottom of the inclined gear disk 302 meshes with an inclined gear 303. The front surface of the inclined gear 303 is fixedly connected to a rotating rod 304. The back surface of the inclined gear 303 is movably connected to a support rod 305. The back surface of the support rod 305 is fixedly connected to the left side of the front surface of the support member 301. The front surface of the rotating rod 304 is fixedly connected to a wiping rod 306. The top of the inclined gear disk 302 is fixedly connected to a wind speed receiving member 307. The bottom of the wiping rod 306 is fixedly connected to an anti-blocking assembly 308.

[0051] The anti-blocking assembly 308 includes a weight iron sheet 308a. The top of the weight iron sheet 308a is fixedly connected to the bottom of the wiping rod 306. A magnetic sheet 308b is magnetically adsorbed to the bottom of the weight iron sheet 308a. The back surface of the magnetic sheet 308b is fixedly connected to a mounting rod 308c. The other end of the mounting rod 308c is fixedly connected to the left side of the connection plate 106.

[0052] Specifically, during the movement of the foldable bracket 101, the wiping rod 306 will wipe the imaging area of the camera 107, improving the imaging clarity of the camera 107 and preventing a large number of water droplets from splashing on the imaging area of the camera 107 due to water splashes generated during the movement of the foldable bracket 101, which may cause rescue personnel to be unable to clearly observe the position and direction of the current foldable floating body 102.

[0053] Specifically, if the moving speed of the foldable bracket 101 is relatively low during the movement, one end of the wiping rod 306 rotates downward, and the weight iron block is attracted and adsorbed by the magnetic sheet 308b, preventing the position where the wiping rod 306 stops rotating from blocking the imaging area of the camera 107 and thus affecting the imaging effect of the camera 107.

[0054] Furthermore, the wind generated during the movement of the foldable bracket 101 blows towards the wind speed receiving member 307, causing the wind speed receiving member 307 to rotate. Then the wind speed receiving member 307 drives the inclined gear disk 302 to rotate. Next, the inclined gear disk 302 drives the inclined gear 303 to rotate, causing the inclined gear 303 to drive the rotating rod 304 to rotate. Subsequently, the rotating rod 304 drives the wiping rod 306 to rotate. At this time, the wiping rod 306 wipes the imaging area of the camera 107, improving the imaging clarity of the camera 107 and preventing a large number of water droplets from splashing on the imaging area of the camera 107 due to water splashes generated during the movement of the foldable bracket 101, which may cause rescue personnel to be unable to clearly observe the position and direction of the current foldable floating body 102.

[0055] Further, if the moving speed of the foldable bracket 101 is relatively low during driving, the splashed water will be relatively small, and not too much water will be splashed on the imaging area of the camera 107. At this time, the wind force is too small to drive the weight of the wiping rod 306 and the weight iron sheet 308a, causing one end of the wiping rod 306 to rotate downward, and attracting and adsorbing the weight iron block through the magnetic sheet 308b, preventing the position where the wiping rod 306 stops rotating from blocking the imaging area of the camera 107 and thus affecting the imaging effect of the camera 107. When the moving speed of the foldable bracket 101 is relatively high during driving, the generated wind speed will be sufficient to drive the weight of the wiping rod 306, the weight iron sheet 308a, and the adsorption force of the magnetic sheet 308b.

[0056] Embodiment 3

[0057] Referring to Figure 1 、 5 、6, this is the third embodiment of the present invention, which provides a heating mechanism 400. Through the heating mechanism 400, auxiliary rewarming of the fallen person is achieved.

[0058] The heating mechanism 400 includes a connecting frame 401. The bottom of the back surface of the connecting frame 401 is fixedly connected to both sides of the front surface of the foldable bracket 101. The bottom of the front surface of the connecting plate 106 is slidably connected to a hand lower pressing plate 402. The top of the connecting frame 401 penetrates through both sides of the top of the hand lower pressing plate 402 and is slidably connected to the hand lower pressing plate 402. Both sides of the front surface of the hand lower pressing plate 402 are inlaid with gauze sleeves 403. Quicklime is stored inside the gauze sleeves 403. The top of the gauze sleeves 403 is fixedly connected to a heat insulation sleeve 404. A waterproof assembly 405 is sleeved on the surface of the gauze sleeves 403. The right side of the top of the hand lower pressing plate 402 is fixedly connected to a water scraping assembly 406.

[0059] The waterproof assembly 405 includes a plastic sleeve 405a. The plastic sleeve 405a is sleeved on the surface of the gauze sleeve 403. The heat insulation sleeve 404 is located inside the plastic sleeve 405a. The front side of the bottom of the plastic sleeve 405a is fixedly connected to a tearing rope 405b. The other end of the tearing rope 405b is fixedly connected to both sides of the connecting plate 106.

[0060] The water scraping assembly 406 includes a rubber water scraping member 406a. The top of the rubber water scraping member 406a is fixedly connected to the top of the hand lower pressing plate 402. A spring 406b is sleeved on the surface of the connecting frame 401.

[0061] Specifically, when a person falling into water climbs onto the inflated collapsible floating body 102, the hand pressing plate 402 is pressed down, causing the quicklime in the gauze sleeve 403 to be dampened and generate heat. The heat generated can warm the body of the person falling into water, preventing the body temperature of the person falling into water from continuously dropping after climbing onto the stretcher rescue mechanism 100 and affecting the life and health of the person falling into water. The person falling into water can feel the heat through the heat insulation sleeve 404, avoiding the situation of scalding due to direct contact between the hand and the gauze sleeve 403 resulting in too high temperature.

[0062] Specifically, before the person falling into water climbs onto the collapsible floating body 102, the surface of the gauze sleeve 403 can be covered and waterproofed by the plastic sleeve 405a, preventing water splashes from hitting the surface of the gauze sleeve 403 during the process of directly driving the collapsible floating body 102 to move, which may cause the quicklime in the gauze sleeve 403 to start generating heat in advance and result in heat loss.

[0063] Specifically, when the hand pressing plate 402 moves up and down, it will drive the rubber wiper 406a to scrape the camera 107 twice, facilitating the preliminary cleaning of the imaging area of the camera 107 before the underwater thruster 105 is turned on again after the person falling into water climbs onto the collapsible floating body 102, so that the rescue personnel can timely confirm the position and the driving direction and then rescue the person falling into water.

[0064] Further, when the person falling into water climbs onto the inflated collapsible floating body 102, the person falling into water can place the hand above the hand pressing plate 402 and then press down the hand pressing plate 402. Then the hand pressing plate 402 will drive the gauze sleeve 403 to move downward and soak in water. When water enters the inside of the gauze sleeve 403, it will cause the quicklime in the gauze sleeve 403 to be dampened and generate heat. The heat generated can warm the body of the person falling into water, preventing the body temperature of the person falling into water from continuously dropping after climbing onto the stretcher rescue mechanism 100 and affecting the life and health of the person falling into water. The person falling into water can feel the heat through the heat insulation sleeve 404, avoiding the situation of scalding due to direct contact between the hand and the gauze sleeve 403 resulting in too high temperature.

[0065] Further, before the person falling into water climbs onto the collapsible floating body 102, the surface of the gauze sleeve 403 can be covered and waterproofed by the plastic sleeve 405a, preventing water splashes from hitting the surface of the gauze sleeve 403 during the process of directly driving the collapsible floating body 102 to move, which may cause the quicklime in the gauze sleeve 403 to start generating heat in advance and result in heat loss. Since one end of the tearing rope 405b is connected to the plastic sleeve 405a and the other end of the tearing rope 405b is connected to the connecting plate 106, when the hand pressing plate 402 moves downward, the bottom of the plastic sleeve 405a will be torn open, facilitating the contact between the gauze sleeve 403 and water.

[0066] Further, when the hand lower pressing plate 402 moves downward, it will squeeze the spring 406b sleeved on the connecting frame 401, causing the spring 406b to generate a resilience force. At the same time, the connecting frame 401 will drive the rubber wiper 406a to scrape the imaging area of the camera 107 once. When the drowning person releases the hand lower pressing plate 402, the hand lower pressing plate 402 will reset through the elastic force of the spring 406b. Then, the hand lower pressing plate 402 will drive the rubber wiper 406a to scrape the camera 107 of the camera 107 for the second time, which is convenient for the drowning person to climb onto the foldable floating body 102 and preliminarily clean the imaging area of the camera 107 before the underwater thruster 105 is turned on again underwater, so as to facilitate the rescue personnel to confirm the position and driving direction in time and drive the drowning person to rescue.

[0067] It should be noted that the hand lower pressing plate 402 is made of copper. By utilizing the advantage of the strong heat conductivity of copper, the temperature when quicklime generates heat can be quickly conducted to the hand lower pressing plate 402, increasing the heating area and ensuring the rising speed of the body temperature of the drowning person.

[0068] The rest of the structure is the same as that of Embodiment 2.

[0069] Embodiment 4

[0070] Refer to Figures 1 to 7 , which is the fourth embodiment of the present invention. The difference between this embodiment and the third embodiment is that this embodiment provides a fire fighting water rescue device and its method.

[0071] When it is necessary to rescue a drowning person in the water, first put the foldable bracket 101 into the water, and then use a remote control adapted to the AIS device 104 to start the underwater thruster 105 to drive the foldable bracket 101 to move. During the process of the foldable bracket 101 moving through the underwater thruster 105, the current position or direction of the foldable bracket 101 can be observed through the camera 107. When it is confirmed that the foldable bracket 101 is directly about to approach the position of the drowning person, then use the remote control to remotely control the electric inflator 103 to turn on through the AIS device 104 to continuously inflate the foldable floating body 102. At this time, the foldable floating body 102 will unfold together with the foldable bracket 101. When it is confirmed that the foldable floating body 102 moves beside the drowning person, turn off the underwater thruster 105 to stop moving, so as to facilitate the drowning person to climb onto the foldable floating body 102. Since the foldable floating body 102 is inflated when it is about to approach the position of the drowning person, the process of inflating before rescue is saved, the rescue efficiency is greatly improved, and the situation of reducing the rescue efficiency due to inflating and then rescuing is avoided.

[0072] During the startup process of the underwater thruster 105, the filter plate 109 can filter aquatic plants or impurities in the water, preventing the aquatic plants or impurities from directly covering the surface of the underwater thruster 105 and causing a significant reduction in the propulsion speed of the underwater thruster 105. Moreover, during the use of the underwater thruster 105, it will also drive the transmission frame 201 to rotate around the protective cover 108. Then, the transmission frame 201 drives the scraping strip 202 to rotate synchronously, enabling the scraping strip 202 to scrape the aquatic plants or impurities filtered on the filter plate 109 to one side of the scraping strip 202 during rotation. The aquatic plants or impurities scraped to one side of the scraping strip 202 will fly outwards under the centrifugal force generated during the rotation of the scraping strip 202, thereby separating the aquatic plants and impurities from the filter plate 109 and preventing the driving speed of the underwater thruster 105 from being affected and thus unable to carry out rescue in a timely manner.

[0073] During the rotation startup process of the underwater thruster 105, it will also drive the movable part 203a to rotate synchronously. Then, the movable part 203a will synchronously drive the transmission part 203b to move up and down along the path of the inner wall of the limiting part 203i. Then, the transmission part 203b will drive the piston rod 203c to move up and down continuously. Whenever the piston rod 203c moves downward, the external water will enter the inside of the piston sleeve 203d through the inlet check valve 203e. Whenever the piston rod 203c moves upward, the water in the piston sleeve 203d will be discharged outwards through the outlet check valve 203f. Then, the water squeezed out will be quickly ejected through the water spray holes 203h of the water spray pipe 203g. At this time, the ejected water flow will impact the aquatic plants and impurities on one side of the scraping strip 202, causing a small part of the aquatic plants that are not affected by the centrifugal force and separated from the scraping strip 202 to be washed away by the ejected water flow, further improving the cleaning effect.

[0074] Moreover, during the rotation of the transmission frame 201, it will synchronously drive the inclined plate 204a to rotate. Then, the inclined plate 204a will drive the stable slider 204b to rotate synchronously along the inner wall of the stable chute 204c, improving the support strength of the inner wall of the transmission frame 201 and preventing the transmission frame 201 from being damaged under high rotational speeds. By utilizing the inclination of the inclined plate 204a, an axial thrust can also be generated during the rotation of the inclined plate 204a, thereby being able to improve the propulsion force of the underwater thruster 105.

[0075] During the movement of the foldable bracket 101, the wind generated will blow towards the wind speed stress member 307, causing the wind speed stress member 307 to rotate. Then, the wind speed stress member 307 will drive the helical gear disk 302 to rotate. Subsequently, the helical gear disk 302 will drive the helical gear 303 to rotate, causing the helical gear 303 to drive the rotating rod 304 to rotate. Then, the rotating rod 304 will drive the wiping rod 306 to rotate. At this time, the wiping rod 306 will wipe the imaging area of the camera 107, improving the imaging clarity of the camera 107 and preventing a large amount of water droplets from splashing on the imaging area of the camera 107 due to water splashes generated during the movement of the foldable bracket 101, which may prevent the rescue personnel from clearly observing the position and direction of the current foldable floating body 102.

[0076] If the moving speed of the foldable bracket 101 is relatively low during the movement, the splashed water will be relatively small. At this time, not too much water will splash on the imaging area of the camera 107. At this time, the wind force is too small to drive the weight of the wiping rod 306 and the weight iron sheet 308a, causing one end of the wiping rod 306 to rotate downward and attracting and adsorbing the weight iron block through the magnetic sheet 308b, preventing the position of the wiping rod 306 from blocking the imaging area of the camera 107 when it stops rotating and thus affecting the imaging effect of the camera 107. When the moving speed of the foldable bracket 101 is relatively high during the movement, the generated wind speed will be sufficient to drive the weight of the wiping rod 306, the weight of the weight iron sheet 308a, and the adsorption force of the magnetic sheet 308b.

[0077] When the drowning person climbs onto the inflated foldable floating body 102, the drowning person can place their hand above the hand lower pressing plate 402 and then press down on the hand lower pressing plate 402. Then, the hand lower pressing plate 402 will drive the gauze sleeve 403 to move downward and soak in the water. After the water enters the gauze sleeve 403, the quicklime inside the gauze sleeve 403 will get damp and generate heat. The generated heat can warm the body of the drowning person, preventing the body temperature of the drowning person from continuously dropping after climbing onto the stretcher rescue mechanism 100 and affecting the life and health of the drowning person. The drowning person can feel the heat through the heat insulation sleeve 404, preventing direct contact between the hand and the gauze sleeve 403 and resulting in burns. It is also possible to drive the lower pressing plate 402 using the weight of the drowning person himself.

[0078] Before the drowning person climbs onto the foldable floating body 102, the surface of the gauze cover 403 can be covered and waterproofed by the plastic cover 405a, avoiding the situation that water splashes on the surface of the gauze cover 403 during the process of directly driving the foldable floating body 102 to move, which causes the quicklime in the gauze cover 403 to start generating heat in advance and results in heat loss. Since one end of the tearing rope 405b is connected to the plastic cover 405a and the other end of the tearing rope 405b is connected to the connecting plate 106, when the hand pressing plate 402 moves downward, the bottom of the plastic cover 405a will be torn, facilitating the contact between the gauze cover 403 and water.

[0079] When the hand pressing plate 402 moves downward, it will squeeze the spring 406b sleeved on the connecting frame 401, causing the spring 406b to generate a resilience force. At the same time, the connecting frame 401 will drive the rubber wiper 406a to scrape the imaging part of the camera 107 once. When the drowning person releases the hand pressing plate 402, the hand pressing plate 402 will be reset by the resilience force of the spring 406b. Then, the hand pressing plate 402 will drive the rubber wiper 406a to scrape the camera 107 of the camera 107 for the second time, facilitating the preliminary cleaning of the imaging part of the camera 107 before the underwater thruster 105 is turned on again after the drowning person climbs onto the foldable floating body 102, so that the rescue personnel can timely confirm the position and the driving direction and then drive the drowning person to be rescued.

[0080] In summary, when it is necessary to rescue a drowning person, by controlling the stretcher rescue mechanism 100 to drive to the side of the drowning person and inflate at the same time, it is convenient for the drowning person to climb onto the stretcher rescue mechanism 100. Moreover, during the use of the stretcher rescue mechanism 100, the anti-deceleration mechanism 200 and the wiping mechanism 300 will be started, which can scrape off waterweeds and wipe the imaging part of the camera 107. After the drowning person climbs onto the stretcher rescue mechanism 100, the heating mechanism 400 can be started to generate heat.
