Description

Technical Field

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

[0002] Water firefighting refers to fire safety management, fire prevention and rescue activities specifically for water areas and water facilities. The main responsibilities include: Fire prevention and drowning prevention: Enhance the public's awareness of fire prevention and drowning prevention through publicity and education activities. Patrol and guard: Regularly patrol the waters to ensure that firefighting facilities are in good condition and promptly discover and deal with safety hazards. Emergency rescue: When a water accident occurs, respond quickly, perform search and rescue tasks, and protect the safety of people's lives and property.

[0003] Water firefighting is a professional fire safety system specially established for fire and emergency rescue situations in aquatic environments. The rescue equipment used for people who fall into the water mainly includes life jackets, lifebuoys, life ropes, inflatable rubber rafts and life stretchers.

[0004] However, in the process of the water rescue stretcher being moved to the rescued person by the underwater propeller, the surface of the underwater propeller is easily adsorbed to the water plants in the water, resulting in the propulsion speed of the underwater propeller being affected, so that it cannot be moved to the rescued person in time. In addition, the rescuer needs to inflate the life-saving stretcher in advance when using the life-saving stretcher, which makes the use process extremely inconvenient. At the same time, the camera device used on the water rescue stretcher will splash water during the movement of the water rescue stretcher, and cause these splashes to splash onto the camera of the camera device, thus affecting the camera effect. At this time, the rescuer who controls the water rescue stretcher to move cannot clearly understand the direction and position of the water rescue stretcher. Summary of the invention

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0032] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0033] Reference Figures 1 to 7 , which is the first embodiment of the present invention, provides a rescue method using a fire-fighting water rescue device. Through the rescue method using the fire-fighting water rescue device, timely inflation is achieved to reduce the interference caused by water plants and water splashes and to assist in warming.

[0034] When it is necessary to rescue a person who has fallen into the water, the stretcher rescue mechanism 100 is controlled to travel to the side of the person who has fallen into the water and inflate at the same time, so that it is convenient for the person who has fallen into the water to climb onto the stretcher rescue mechanism 100. Inflation during travel can greatly improve the rescue efficiency and avoid the situation where rescue is performed after inflation, resulting in reduced rescue efficiency. During the travel of the stretcher rescue mechanism 100, the anti-deceleration mechanism 200 is activated to continuously scrape off the waterweed or other foreign matter attached to the stretcher rescue mechanism 100, so as to prevent the waterweed and foreign matter from attaching to the stretcher rescue mechanism 100, thereby reducing the travel speed of the stretcher rescue mechanism 100 and thus failing to perform rescue in time; When the stretcher rescue mechanism 100 is traveling at a relatively fast speed, the wiping mechanism 300 is activated to continuously wipe the camera position of the camera 107 on the stretcher rescue mechanism 100, thereby improving the camera clarity of the camera 107 and preventing the rescue personnel from being unable to clearly observe the current traveling position and direction of the stretcher rescue mechanism 100 during the traveling process; When the drowning person climbs onto the stretcher rescue mechanism 100 , the heating mechanism 400 can be started to generate heat, thereby increasing the body temperature of the drowning person, thereby preventing the drowning person from continuously losing body temperature after climbing onto the stretcher rescue mechanism 100 and affecting the life and health of the drowning person.

[0035] Reference Figure 1 , 7 , which is a second embodiment of the present invention, provides a wiping mechanism 300, through which auxiliary wiping of water stains is achieved.

[0036] 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 side of the connecting plate 106, the other end of the support member 301 is movably connected to a beveled toothed disc 302, the front side of the bottom of the beveled toothed disc 302 is meshed with a bevel gear 303, the front side of the beveled gear 303 is fixedly connected to a rotating rod 304, the back side of the beveled gear 303 is movably connected to a support rod 305, the back side of the support rod 305 is fixedly connected to the left side of the front side of the support member 301, the front side of the rotating rod 304 is fixedly connected to a wiping rod 306, the top of the beveled toothed disc 302 is fixedly connected to a wind speed force bearing member 307, and the bottom of the wiping rod 306 is fixedly connected to an anti-shielding component 308.

[0037] The anti-shielding component 308 includes a counterweight iron sheet 308a, the top of the counterweight iron sheet 308a is fixedly connected to the bottom of the wiping rod 306, the bottom of the counterweight iron sheet 308a is magnetically adsorbed with a magnetic sheet 308b, the back of the magnetic sheet 308b is fixedly connected to a mounting rod 308c, and the other end of the mounting rod 308c is fixedly connected to the left side of the connecting plate 106.

[0038] Specifically, during the movement of the foldable bracket 101, the wiping rod 306 will wipe the camera 107 to improve the camera clarity of the camera 107 and avoid splashing water during the movement of the foldable bracket 101, causing a large amount of water droplets to splash on the camera 107, making it impossible for rescue personnel to clearly observe the current position and direction of the foldable float 102.

[0039] Specifically, if the foldable bracket 101 moves at a low speed during driving, one end of the wiping rod 306 rotates downward and attracts and adsorbs the counterweight iron block through the magnetic sheet 308b to prevent the current position of the wiping rod 306 when it stops rotating from blocking the camera 107 and affecting the camera effect of the camera 107.

[0040] Furthermore, the wind generated during the movement of the foldable bracket 101 will blow toward the wind speed force bearing member 307, causing the wind speed force bearing member 307 to rotate, and then the wind speed force bearing member 307 will drive the bevel gear plate 302 to rotate, and then the bevel gear plate 302 will drive the bevel gear 303 to rotate, so that the bevel gear 303 drives the rotating rod 304 to rotate, and then the rotating rod 304 will drive the wiping rod 306 to rotate, and then the rotating rod 304 will drive the wiping rod 306 to rotate, and then the wiping rod 306 will wipe the camera 107 to improve the camera clarity of the camera 107, and avoid the generation of splashes during the travel of the foldable bracket 101, causing a large amount of water droplets to splash on the camera 107, making it impossible for rescue personnel to clearly observe the current travel position and direction of the foldable float 102.

[0041] Furthermore, if the foldable bracket 101 moves at a low speed during driving, the splashes of water will be small, and not too much water will splash on the camera 107. The wind force at this time is too small to drive the weight of the wiping rod 306 and the weight of the counterweight iron sheet 308a, so that one end of the wiping rod 306 rotates downward, and the counterweight iron block is attracted and adsorbed through the magnetic sheet 308b, to avoid the current position of the wiping rod 306 when it stops rotating from blocking the camera 107 and affecting the camera effect of the camera 107. When the foldable bracket 101 moves at a high speed during driving, the wind speed generated will be sufficient to drive the weight of the wiping rod 306, the weight of the counterweight iron sheet 308a and the adsorption force of the magnetic sheet 308b.

[0042] Reference Figure 1 , 5 6 is the third embodiment of the present invention, which provides a heating mechanism 400, through which the heating mechanism 400 is used to assist in warming up the person who falls into the water.

[0043] The heating mechanism 400 includes a connecting frame 401, the bottom of the back side of the connecting frame 401 is fixedly connected to the two sides of the front side of the foldable bracket 101, the bottom of the front side of the connecting plate 106 is slidably connected to the hand pressing plate 402, the top of the connecting frame 401 passes through the two sides of the top of the hand pressing plate 402 and is slidably connected to the hand pressing plate 402, both sides of the front side of the hand pressing plate 402 are inlaid with gauze covers 403, quicklime is stored inside the gauze covers 403, the top of the gauze covers 403 is fixedly connected to the heat insulation cover 404, the surface of the gauze covers 403 is provided with a waterproof component 405, and the right side of the top of the hand pressing plate 402 is fixedly connected to the wiper component 406.

[0044] The waterproof component 405 includes a plastic cover 405a, which is mounted on the surface of the gauze cover 403. The heat-insulating cover 404 is located inside the plastic cover 405a. A tear rope 405b is fixedly connected to the front side of the bottom of the plastic cover 405a, and the other end of the tear rope 405b is fixedly connected to both sides of the connecting plate 106.

[0045] The wiper assembly 406 includes a rubber wiper member 406 a , the top of the rubber wiper member 406 a is fixedly connected to the top of the hand pressing plate 402 , and a spring 406 b is sleeved on the surface of the connecting frame 401 .

[0046] Specifically, when the person who falls into the water climbs onto the inflated foldable float 102, the hand pressure plate 402 is pressed down, so that the quicklime in the gauze cover 403 becomes damp and generates heat. The generated heat can be used to warm up the body of the person who falls into the water, thereby preventing the person who falls into the water from continuing to lose body temperature after climbing onto the stretcher rescue mechanism 100, which may affect the life and health of the person who falls into the water. The person who falls into the water can feel the heat through the insulation cover 404, thereby preventing the hand from directly contacting the gauze cover 403, which may cause burns due to excessive temperature.

[0047] Specifically, before the person who falls into the water climbs onto the foldable float 102, the surface of the gauze cover 403 can be covered and waterproofed by the plastic cover 405a, so as to avoid the situation in which the foldable float 102 is directly driven by the foldable body to move and water splashes on the surface of the gauze cover 403, causing the quicklime in the gauze cover 403 to start generating heat prematurely and cause heat loss.

[0048] Specifically, when the hand pressure plate 402 moves up and down, it will drive the rubber wiper 406a to scrape the camera 107 twice, so that after the person who falls into the water climbs onto the foldable float 102, the camera 107 can be preliminarily cleaned before the underwater propeller 105 is turned on again, so that the rescue personnel can promptly confirm the position and direction of travel and drive the person who falls into the water to carry out rescue.

[0049] Furthermore, when the person who falls into the water climbs onto the inflated foldable float 102, the person who falls into the water can place his hands on the hand pressure plate 402 and then press down on the hand pressure plate 402, and then the hand pressure plate 402 will drive the gauze cover 403 to move downward and soak in the water, so that after the water enters the gauze cover 403, the quicklime in the gauze cover 403 will become damp and generate heat. The generated heat can be used to warm up the body of the person who falls into the water, avoiding the continuous loss of body temperature after the person who falls into the water climbs onto the stretcher rescue mechanism 100, which will affect the life and health of the person who falls into the water. The person who falls into the water can feel the heat through the insulation cover 404, avoiding direct contact between the hands and the gauze cover 403, which will cause burns due to excessive temperature.

[0050] Furthermore, before the person who falls into the water climbs onto the foldable float 102, the surface of the gauze cover 403 can be covered and waterproofed by the plastic cover 405a to prevent water from splashing on the surface of the gauze cover 403 during the process of the foldable float 102 being directly driven to move, causing the quicklime in the gauze cover 403 to start generating heat prematurely and causing heat loss. Since one end of the tear rope 405b is connected to the plastic cover 405a and the other end of the tear rope 405b is connected to the connecting plate 106, after the hand pressure plate 402 moves downward, the bottom of the plastic cover 405a will be torn open, thereby facilitating the contact between the gauze cover 403 and water.

[0051] Furthermore, when the hand pressure plate 402 moves downward, it will squeeze the spring 406b mounted on the connecting frame 401, causing the spring 406b to generate a rebound force. At the same time, the connecting frame 401 will drive the rubber wiper 406a to scrape the camera 107 once, and when the person who falls into the water releases the hand pressure plate 402, the hand pressure plate 402 is reset by the elastic force of the spring 406b, and then the hand pressure plate 402 will again drive the rubber wiper 406a to scrape the camera 107 for the second time, so that the person who falls into the water can climb onto the foldable float 102 and perform a preliminary cleaning of the camera 107 before the underwater propeller 105 is turned on again, so that the rescue personnel can promptly confirm the position and driving direction, thereby leading the person who falls into the water to carry out rescue.

[0052] It should be noted that the hand pressure plate 402 is made of metal copper. By utilizing the strong thermal conductivity of metal copper, the heat generated by quicklime can be quickly transferred to the hand pressure plate 402, thereby increasing the heating area and ensuring the speed at which the body temperature of the person falling into the water rises.

[0053] The remaining structure is the same as that of Example 2.

[0054] Reference Figures 1 to 7, which is the fourth embodiment of the present invention. This embodiment is different from the third embodiment in that: this embodiment provides a fire-fighting water rescue device and method.

[0055] When it is necessary to rescue a person who has fallen into the water, the foldable support 101 is first placed in the water, and then the remote controller compatible with the AIS device 104 is used to start the underwater pusher 105 to drive the foldable support 101 to move. During the movement of the foldable support 101 by the underwater pusher 105, the current position or direction of the foldable support 101 can be observed through the camera 107. When it is confirmed that the foldable support 101 is about to approach the position of the person who has fallen into the water, the remote controller is used to remotely control the electric inflator through the AIS device 104. 103 is opened to continuously inflate the foldable float 102, and the foldable float 102 will be unfolded together with the foldable bracket 101. When it is confirmed that the foldable float 102 has moved to the side of the person who falls into the water, the underwater propeller 105 is closed and stops moving, so that the person who falls into the water can climb onto the foldable float 102. Since the foldable float 102 is inflated when it is about to approach the position of the person who falls into the water, the process of inflating before rescue is saved, the rescue efficiency is greatly improved, and the situation where rescue efficiency is reduced due to rescue after inflation is avoided.

[0056] During the start-up of the underwater propeller 105, the filter plate 109 can be used to filter aquatic plants or impurities in the water, preventing the aquatic plants or impurities from directly covering the surface of the underwater propeller 105, which would cause a significant reduction in the propulsion speed of the underwater propeller 105. During use, the underwater propeller 105 will also drive the transmission frame 201 to rotate around the protective cover 108, and then the transmission frame 201 drives the scraper bar 202 to rotate synchronously, so that the scraper bar 202 can scrape the aquatic plants or impurities filtered on the filter plate 109 to one side of the scraper bar 202 during the rotation process, and the aquatic plants or impurities scraped to one side of the scraper bar 202 will fly outward under the centrifugal force generated when the scraper bar 202 rotates, thereby separating the aquatic plants and impurities from the filter plate 109, thereby preventing the driving speed of the underwater propeller 105 from being affected and thus failing to carry out rescue in time.

[0057] During the process of the underwater propeller 105 starting to rotate, it will also drive the movable part 203a to rotate synchronously, and 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 limit part 203i, and 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 interior of the piston sleeve 203d through the water inlet check valve 203e. Whenever the piston rod 203c moves upward, the water in the piston sleeve 203d will be discharged outward through the water outlet check valve 203f, and then the squeezed and discharged water will be quickly sprayed out through the water spray hole 203h of the water spray pipe 203g. At this time, the sprayed water flow will impact the water plants and impurities on one side of the scraper bar 202, so that a small part of the water plants that are not affected by the centrifugal force and separated from the scraper bar 202 are flushed away by the sprayed water flow, thereby further improving the cleaning effect.

[0058] And during the rotation of the transmission frame 201, the inclined plate 204a will be driven to rotate synchronously, and then the inclined plate 204a will drive the stabilizing slider 204b to rotate synchronously along the inner wall of the stabilizing slide groove 204c, thereby improving the supporting strength of the inner wall of the transmission frame 201 and avoiding the transmission frame 201 from being damaged under high rotation speed. By utilizing the inclination of the inclined plate 204a, the inclined plate 204a can also generate axial thrust during the rotation process, thereby improving the propulsion power of the underwater propeller 105.

[0059] The wind generated during the movement of the foldable bracket 101 will blow towards the wind speed force bearing member 307, causing the wind speed force bearing member 307 to rotate, and then the wind speed force bearing member 307 will drive the bevel gear plate 302 to rotate, and then the bevel gear plate 302 will drive the bevel gear 303 to rotate, so that the bevel gear 303 drives the rotating rod 304 to rotate, and then the rotating rod 304 will drive the wiping rod 306 to rotate, and then the rotating rod 304 will drive the wiping rod 306 to rotate, and then the wiping rod 306 will wipe the camera 107 to improve the camera clarity of the camera 107, and avoid the generation of splashes during the travel of the foldable bracket 101, causing a large amount of water droplets to splash on the camera 107, so that the rescue personnel cannot clearly observe the current travel position and direction of the foldable float 102.

[0060] If the foldable bracket 101 moves at a low speed during driving, the splashes of water will be small, and not too much water will splash on the camera 107. The wind force at this time is too small to drive the weight of the wiping rod 306 and the weight of the counterweight iron sheet 308a, so that one end of the wiping rod 306 rotates downward, and the counterweight iron block is attracted and adsorbed through the magnetic sheet 308b, to avoid the position of the current wiping rod 306 when it stops rotating from blocking the camera 107 and affecting the camera effect of the camera 107. When the foldable bracket 101 moves at a high speed during driving, the wind speed generated will be sufficient to drive the weight of the wiping rod 306, the weight of the counterweight iron sheet 308a and the adsorption force of the magnetic sheet 308b.

[0061] When the person who falls into the water climbs onto the inflated foldable float 102, the person who falls into the water can place his hands on the hand pressure plate 402 and then press down on the hand pressure plate 402, and then the hand pressure plate 402 will drive the gauze cover 403 to move downward and soak in the water, so that after the water enters the gauze cover 403, the quicklime in the gauze cover 403 will become damp and generate heat. The generated heat can be used to warm up the body of the person who falls into the water, avoiding the continuous loss of body temperature after the person who falls into the water climbs onto the stretcher rescue mechanism 100, which will affect the life and health of the person who falls into the water. The person who falls into the water can feel the heat through the insulation cover 404, avoiding the situation that the hand directly contacts the gauze cover 403, which may cause burns due to excessive temperature, and the person who falls into the water can also use his own weight to drive the pressure plate 402.

[0062] Before the person who falls into the water climbs onto the foldable float 102, the surface of the gauze cover 403 can be covered and waterproofed by the plastic cover 405a to prevent water from splashing on the surface of the gauze cover 403 during the process of the foldable float 102 being directly driven to move, causing the quicklime in the gauze cover 403 to start generating heat prematurely and causing heat loss. Since one end of the tear rope 405b is connected to the plastic cover 405a and the other end of the tear rope 405b is connected to the connecting plate 106, after the hand pressure plate 402 moves downward, the bottom of the plastic cover 405a will be torn open, thereby facilitating the contact between the gauze cover 403 and the water.

[0063] When the hand pressure plate 402 moves downward, it will squeeze the spring 406b mounted on the connecting frame 401, causing the spring 406b to generate a rebound force. At the same time, the connecting frame 401 will drive the rubber wiper 406a to scrape the camera 107 once, and when the person who falls into the water releases the hand pressure plate 402, the hand pressure plate 402 is reset by the elastic force of the spring 406b, and then the hand pressure plate 402 will again drive the rubber wiper 406a to scrape the camera 107 for the second time, so that the person who falls into the water can climb onto the foldable float 102 and perform a preliminary cleaning of the camera 107 before the underwater propeller 105 is turned on again, so that the rescue personnel can promptly confirm the position and driving direction, thereby leading the person who falls into the water to carry out rescue.

[0064] In summary, when it is necessary to rescue a person who has fallen into the water, the stretcher rescue mechanism 100 is controlled to travel to the side of the person who has fallen into the water and inflate it at the same time, so that it is convenient for the person who has fallen into the water to climb onto the stretcher rescue mechanism 100, and during the use of the stretcher rescue mechanism 100, the anti-deceleration mechanism 200 and the wiping mechanism 300 will be activated to scrape off the water plants and wipe the camera 107. After the person who has fallen into the water climbs onto the stretcher rescue mechanism 100, the heating mechanism 400 can be activated to generate heat.
