[0002] In the environment we live in, there are a large number of park artificial lakes, reservoirs, and lakes, but due to inadequate safety measures, blind spots and dead angles in monitoring, and lack of life-saving awareness, it often causes accidents of falling into the water, and is more likely to cause drowning deaths. At present, the personal protective equipment equipped for water fire rescue, such as life buoys, has a slow rescue response speed, and rescuers need to carry the life buoy from the shore to the place where people fall into the water, which easily consumes the physical strength of rescuers.

[0003] In the prior art, the invention patent with patent application number CN201910733505.1 discloses a life-saving device that can quickly recover a life buoy. The life buoy is accurately thrown near the drowning person through a catapult device, which is more convenient and labor-saving for the rescue personnel, and increases the success rate of rescue.

[0018] Preferably, a fixed pulley is provided on the mounting seat, and the winding rope is slidably connected to the fixed pulley.

[0019] The present invention also discloses a method for using a combined firefighting and rescue device for rescuing people falling into water, comprising the following steps:

[0020] S1: After the personnel on the shore find a person who has fallen into the water, they manually turn the mounting seat so that the mounting seat drives the rotating seat and the slide to rotate relative to the base, so that the opening of the slide faces the place where the person has fallen into the water;

[0021] S2: Then the first motor and the second motor are controlled to operate, and at the same time the rescuer swims towards the place where the person falls into the water;

[0022] When the first motor is working, it drives the incomplete gear to rotate through the driving rod. When the incomplete gear is meshed with the driven gear, the driven gear drives the rotating rod and the first drum on the rotating rod to rotate. The first drum reels the pull rope, and the pull rope pulls the push seat to move down in the slideway. The rescue piece moves down with the slideway, and the third elastic element is compressed. As the incomplete gear continues to rotate, the incomplete gear is no longer meshed with the driven gear, and the driven gear is no longer restricted. The third elastic element recovers and pushes the push seat to move, so that the push seat ejects the rescue piece, and the rescue piece flies along the slideway to the place where the person falls into the water.

[0023] When the second motor is working, it drives the second drum to rotate through the driving shaft, so that the winding rope is released from the second drum as the rescue device is ejected;

[0024] S3: After the ejected rescue component falls to the water body near where the person falls into the water, the floating plate moves upward under the action of its own buoyancy, and the floating plate drives the square rod to move. The square rod pushes the first limit plate through the first baffle plate or pushes the second limit plate through the second baffle plate, so that the slide bar and the slide tube move relative to each other, the slide bar moves out of the slide tube, and the restriction between the first shell and the second shell is released. The second shell is reset and rotated under the action of the torsion spring, so that the second shell moves away from the first shell with the connecting shaft as the center, and the airbag strips between the first shell and the second shell are expanded to increase the deployment area of ​​the rescue component;

[0025] When the floating plate moves, the connecting rod drives the blocking block to move in the movable groove at the same time, and the blocking block no longer blocks the water storage tank. The water stored in the water storage tank flows out through the movable groove, thereby reducing the self-weight of the rescue device.

[0026] If the first shell and the second shell cannot be separated normally, the staff can also manually push the floating plate to move the first shell and the second shell to open, thereby expanding the gripping area of ​​the rescue piece;

[0027] S4: The rescuer who swims to the vicinity of the rescue device carries the rescue device with reduced weight and moves to the point where the person falls into the water not far away;

[0028] If the drowning person is in a lying position with his head up waiting for rescue or in a half-sunken position, the rescuer will hold the rescue device and pull up the drowning person;

[0029] If the drowning person is struggling with his hands raised, the rescuer will first place the airbag strip of the rescue device in front of the drowning person, so that the drowning person can grab the airbag strip or the rope on the airbag strip while struggling. The rescuer will assist in controlling the position of the rescue device so that the drowning person can grab it easily.

[0030] After the rescuer assists the person who falls into the water to hold the rescue device steadily, the remote control switch on the rescue device is controlled to make the second motor drive the second drum to rotate through the drive shaft, and the second drum reels the reeling rope. As the reeling rope is reeled, the rescue device drives the rescuer and the person who falls into the water to move toward the shore.

[0031] Compared with the prior art, the present invention provides a fire rescue combined device for water rescue and a method of using the same, which has the following beneficial effects:

[0032] 1. The fire rescue combined device for water rescue and the use method thereof eject the rescue piece through the ejection mechanism, so that the rescue piece flies in the air with a narrow surface, reduces the resistance encountered by the rescue piece during flight, increases the ejection distance of the rescue piece, reduces the rescue personnel's need to carry the rescue piece for a long distance, saves labor, and the rescue piece that falls on the water surface automatically stretches out, expanding the gripping area of ​​the rescue piece, making it easier for rescue personnel and the person who falls into the water to grab it, thereby improving the timeliness and success rate of rescue for water accidents and reducing the risk of rescue.

[0033] 2. The fire rescue combined device for rescuing people who fall into water and the method of using the same are connected by a first shell and a second shell through a rescue piece. The first shell and the second shell are separated after falling into water, and a plurality of airbag strips between the first shell and the second shell are automatically inflated. The airbag strips are narrower than the cross-section of a life buoy, and a plurality of hanging ropes are provided at the bottom of the airbag strips, which are convenient for people who fall into water to hold, thereby improving the success rate of rescue.

[0034] 3. The fire rescue combination device for rescuing people who fall into water and the method of using the same, by providing a water storage tank in the rescue piece, it is convenient to increase the self-gravity of the rescue piece. Since inertia is proportional to the mass of an object, the rescue piece is heavier than a life buoy, so that the rescue piece can be ejected at a farther distance, thereby reducing the moving distance of the rescue personnel carrying the rescue piece. After the rescue piece falls into water, the blocking block no longer blocks the water storage tank, and the water in the water storage tank leaks out, reducing the counterweight of the rescue piece, making it convenient for the rescue personnel to carry the rescue piece to the place where the person falls into the water, saving the physical labor of the rescue personnel, greatly increasing the success rate of the rescue, and reducing the risk of rescue.

DETAILED DESCRIPTION

[0047] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0048] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the 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 element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0049] Example 1: Reference Figure 1 , Figure 2 and Figure 3 A fire rescue combined device for water rescue comprises a base 1 fixed on the shore, and also comprises:

[0050] A rotating seat 2 is rotatably arranged on the base 1, a mounting seat 3 is fixedly arranged on the rotating seat 2, and a slideway 4 is fixedly arranged on the top of the mounting seat 3;

[0051] A rescue member 5, the rescue member 5 is slidably arranged in the slideway 4;

[0052] An ejection mechanism 6, which is disposed on the slide 4 and is used to drive the rescue member 5 to slide in the slide 4 and eject it into the water area; and

[0053] The reeling mechanism 7 is arranged in the mounting seat 3 and is used for recovering the rescue component 5 ejected into the water area.

[0054] The rescuer 5 can then move the rescuer 5 in the water and the rescuer 5 can then move the rescuer 5 back to the shore, so that the rescuer 5 can move back to the shore quickly.

[0055] Example 2: Reference Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 A firefighting and rescue combination device for rescuing people who fall into water, based on Example 1, further, the rescue component 5 includes a first shell 501 and a second shell 502, the first shell 501 is rotatably provided with a connecting shaft 503 connected to the second shell 502, the connecting shaft 503 is sleeved with a torsion spring 504 whose two ends are respectively abutted against the first shell 501 and the second shell 502, a locking assembly is provided at one end of the first shell 501 and the second shell 502 away from the connecting shaft 503, the first shell 501 and the second shell 502 are both provided with grooves 8, and a plurality of airbag strips 801 are provided between the inner walls of the two grooves 8.

[0056] Furthermore, a plurality of hanging ropes 9 are provided on the airbag strip 801 , and a plurality of anti-falling knots 901 are provided on each hanging rope 9 .

[0057] Specifically, the first shell 501 and the second shell 502 of the rescue component 5 are made of plastic material that is easy to float in water. After the rescue component 5 is ejected into the water, the locking assembly automatically releases the restriction on the first shell 501 and the second shell 502. The second shell 502 is moved away from the first shell 501 under the action of the torsion spring 504. The several airbag strips 801 between the first shell 501 and the second shell 502 are unfolded to increase the unfolding area of ​​the rescue component 5. The airbag strip 801 is narrower than the cross-section of the lifebuoy, and several hanging ropes 9 are arranged at the bottom of the airbag strip 801 for the person who falls into the water to grab. The multiple anti-slip knots 901 arranged on the hanging rope 9 can prevent the person who falls into the water from slipping easily after grabbing the hanging rope 9, thereby improving the success rate of rescue.

[0058] Example 3: Reference Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 , a fire rescue combination device for rescuing people falling into water, based on Example 2, further, the locking assembly includes a first locking block 5011 fixedly connected to the first shell body 501 and a second locking block 5021 fixedly connected to the second shell body 502, a sliding rod 5012 is slidably connected in the first locking block 5011, a first limiting plate 5013 is fixedly provided at the end of the sliding rod 5012, a first elastic element 5014 whose two ends are respectively connected to the first limiting plate 5013 and the first locking block 5011 is sleeved on the outer side of the sliding rod 5012, a sliding tube 5022 is slidably connected in the second locking block 5021, the sliding rod 5012 is inserted in the sliding tube 5022, a second limiting plate 5023 is fixedly provided at the end of the sliding tube 5022, and a second elastic element 5024 whose two ends are respectively connected to the second limiting plate 5023 and the second locking block 5021 is sleeved on the outer side of the sliding tube 5022.

[0059] Furthermore, a square rod 10 is slidably connected inside the first locking block 5011, and the square rod 10 is provided with a first baffle 1001 that movably abuts against the first limiting plate 5013 and a second baffle 1002 that movably abuts against the second limiting plate 5023. Both ends of the square rod 10 are also provided with floating plates 1003 that float in the water.

[0060] Specifically, when the rescue piece 5 has not fallen into the water, the slide bar 5012 is inserted into the slide tube 5022, and the first shell 501 and the second shell 502 are in a locked state. The rescue piece 5 has a small area, so that the wind resistance it encounters during the ejection flight is small, which increases its ejection distance, reduces the distance that subsequent rescuers carry the rescue piece 5 to move to the person who falls into the water, and saves the physical energy consumption of the rescuers. After the ejected rescue piece 5 falls to the water body near the person who falls into the water, the floating plate 1003 moves up under the action of its own buoyancy, and the floating plate 1003 drives the square rod 10 to move, and the square rod 10 passes through the first baffle 100. The first limiting plates 5013 abut against and push, or the second limiting plates 5023 abut against and push through the second baffle plate 1002, so that the slide bar 5012 and the slide tube 5022 move relative to each other, the slide bar 5012 moves out of the slide tube 5022, and the restriction between the first shell 501 and the second shell 502 is released. The second shell 502 is reset and rotated under the action of the torsion spring 504, so that the second shell 502 moves away from the first shell 501 with the connecting shaft 503 as the center, and the several airbag strips 801 between the first shell 501 and the second shell 502 are expanded to increase the deployment area of ​​the rescue component 5.

[0061] Example 4: Reference Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 and Fig.11 A fire rescue combination device for rescuing people who fall into water, based on Example 3, further, a water tank 11 is provided on the first shell 501, and a movable groove 12 connected to the water tank 11 is provided through the first shell 501 from top to bottom, and a blocking block 121 is slidably connected in the movable groove 12, and a connecting rod 122 connected to the floating plate 1003 is provided on the outside of the blocking block 121.

[0062] Specifically, water is stored in the water tank 11 of the first shell 501, so as to avoid the first shell 501, the second shell 502 and the airbag strip 801 using light materials to make the rescue piece 5 float, resulting in a short ejection distance of the rescue piece 5, which is convenient for increasing the self-gravity of the rescue piece 5. Since inertia is proportional to the mass of an object, the rescue piece 5 is heavier than the lifebuoy, which makes the rescue piece 5 ejected at a longer distance, thereby reducing the moving distance of the rescue personnel carrying the rescue piece 5; and after the rescue piece 5 falls into the water, the floating plate 1003 moves and at the same time drives the blocking block 121 to move in the movable groove 12 through the connecting rod 122. The blocking block 121 no longer blocks the water tank 11, and the water stored in the water tank 11 flows out through the movable groove 12, reducing the self-weight of the rescue piece 5, making it convenient for the rescue personnel to carry the rescue piece 5 to the place where the person falls into the water, saving the physical labor of the rescue personnel, greatly increasing the success rate of the rescue, and reducing the risk of rescue.

[0063] Example 5: Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 , a firefighting and rescue combination device for falling into water rescue, based on embodiment 3, further, the ejection mechanism 6 includes a support plate 13 fixedly arranged at the end of the slide 4, the support plate 13 is rotatably connected with a driving rod 131 and a rotating rod 132, a first motor 15 for driving the driving rod 131 to rotate is provided on the support plate 13, an incomplete gear 1311 is provided on the driving rod 131, a driven gear 1321 meshing with the incomplete gear 1311 is provided on the rotating rod 132, a first reel 1322 is provided on the rotating rod 132, a pull rope 14 is wound around the first reel 1322, one end of the pull rope 14 away from the first reel 1322 passes through the slide 4 and is connected with a push seat 141, a third elastic element 142 is provided between the push seat 141 and the inner wall of the slide 4, and a side of the push seat 141 away from the third elastic element 142 is movably opposed to the rescue component 5.

[0064] Specifically, when the ejection mechanism 6 is working, the first motor 15 drives the incomplete gear 1311 to rotate through the driving rod 131. When the incomplete gear 1311 is engaged with the driven gear 1321, the driven gear 1321 drives the rotating rod 132 and the first reel 1322 on the rotating rod 132 to rotate, and the first reel 1322 reels the pull rope 14, and the pull rope 14 pulls the push seat 141 to move downward in the slide 4. The rescue component 5 moves downward with the downward movement of the slide 4, and the third elastic element 142 is compressed. As the incomplete gear 1311 continues to rotate, the incomplete gear 1311 is no longer engaged with the driven gear 1321, and the driven gear 1321 is no longer restricted. The third elastic element 142 recovers and pushes the push seat 141 to move, so that the push seat 141 ejects the rescue component 5, and the rescue component 5 flies along the slide 4 to the place where the person falls into the water.

[0065] Example 6: Reference Figure 2 , Figure 3 and Figure 5 A fire rescue combination device for rescuing people who fall into water, based on Example 5, further, the winding mechanism 7 includes a second motor 16 fixedly arranged in the mounting seat 3, the output shaft of the second motor 16 is connected to the driving shaft 161, the driving shaft 161 is provided with a second drum 162, the second drum 162 is wound with a winding rope 163, the end of the winding rope 163 away from the second drum 162 passes through the slide 4 and is connected to the rescue component 5, and the rescue component 5 is provided with a remote control switch electrically connected to the second motor 16.

[0066] Furthermore, a fixed pulley 17 is provided on the mounting seat 3 , and the winding rope 163 is slidably connected to the fixed pulley 17 .

[0067] Specifically, when the ejection mechanism 6 ejects the rescue component 5, the second motor 16 drives the second drum 162 to rotate through the driving shaft 161 when working, so that the winding rope 163 is released from the second drum 162 as the rescue component 5 is ejected, and the setting of the fixed pulley 17 can guide the moving direction of the winding rope 163. After the rescue personnel assist the drowning person to hold the rescue component 5 stably, the remote control switch on the rescue component 5 is controlled to make the second motor 16 drive the second drum 162 to rotate through the driving shaft 161, and the second drum 162 winds the winding rope 163. The rescue component 5 drives the rescue personnel and the drowning person to move to the shore as the winding rope 163 is wound, which saves the physical labor of the rescue personnel, greatly increases the success rate of the rescue, and reduces the risk of rescue.

[0068] The present invention also discloses a method for using a combined firefighting and rescue device for rescuing people falling into water, comprising the following steps:

[0069] S1: After the personnel on the shore find that a person has fallen into the water, they manually turn the mounting seat 3 so that the mounting seat 3 drives the rotating seat 2 and the slide 4 to rotate relative to the base 1, so that the opening of the slide 4 faces the place where the person falls into the water;

[0070] S2: Then the first motor 15 and the second motor 16 are controlled to operate, and at the same time the rescuer swims towards the place where the person falls into the water;

[0071] When the first motor 15 is working, it drives the incomplete gear 1311 to rotate through the driving rod 131. When the incomplete gear 1311 is meshed with the driven gear 1321, the driven gear 1321 drives the rotating rod 132 and the first reel 1322 on the rotating rod 132 to rotate, and the first reel 1322 reels the pull rope 14, and the pull rope 14 pulls the push seat 141 to move downward in the slide 4, and the rescue piece 5 moves downward with the slide 4, and the third elastic element 142 is compressed. As the incomplete gear 1311 continues to rotate, the incomplete gear 1311 is no longer meshed with the driven gear 1321, and the driven gear 1321 is no longer restricted, and the third elastic element 142 recovers and pushes the push seat 141 to move, so that the push seat 141 ejects the rescue piece 5, and the rescue piece 5 flies along the slide 4 to the place where the person falls into the water;

[0072] When the second motor 16 is working, it drives the second drum 162 to rotate through the driving shaft 161, so that the winding rope 163 is released from the second drum 162 as the rescue member 5 is ejected;

[0073] S3: After the ejected rescue component 5 falls to the water body near where the person falls into the water, the floating plate 1003 moves upward under the action of its own buoyancy, and the floating plate 1003 drives the square rod 10 to move. The square rod 10 pushes the first limit plate 5013 through the first baffle 1001 or pushes the second limit plate 5023 through the second baffle 1002, so that the slide bar 5012 and the slide tube 5022 move relative to each other, and the slide bar 5012 moves out of the slide tube 5022, so that the restriction between the first shell 501 and the second shell 502 is released, and the second shell 502 is reset and rotated under the action of the torsion spring 504, so that the second shell 502 is away from the first shell 501 with the connecting shaft 503 as the center, and the plurality of airbag strips 801 between the first shell 501 and the second shell 502 are expanded to increase the deployment area of ​​the rescue component 5;

[0074] When the floating plate 1003 moves, the blocking block 121 is driven to move in the movable groove 12 through the connecting rod 122, and the blocking block 121 no longer blocks the water storage tank 11, and the water stored in the water storage tank 11 flows out through the movable groove 12, thereby reducing the self-weight of the rescue component 5;

When the incomplete gear (1311) is meshed with the driven gear (1321), the driven gear (1321) drives the rotating rod (132) and the first reel (1322) on the rotating rod (132) to rotate. The first reel (1322) reels the pull rope (14). The pull rope (14) pulls the push seat (141) downward in the slideway (4). The rescue piece (5) As the slideway (4) moves downward, the third elastic element (142) is compressed. As the incomplete gear (1311) continues to rotate, the incomplete gear (1311) is no longer meshed with the driven gear (1321). The driven gear (1321) is no longer restricted. The third elastic element (142) recovers and pushes the push seat (141) to move, so that the push seat (141) ejects the rescue piece (5). The rescue piece (5) flies along the slideway (4) toward the place where the person falls into the water. When the second motor (16) is in operation, it drives the second drum (162) to rotate via the driving shaft (161), so that the winding rope (163) is released from the second drum (162) as the rescue component (5) is ejected; S3: After the ejected rescue component (5) falls to the water body near the person who fell into the water, the floating plate (1003) moves upward under the action of its own buoyancy, and the floating plate (1003) drives the square rod (10) to move. The square rod (10) pushes the first limit plate (5013) through the first baffle plate (1001) or pushes the second limit plate (5023) through the second baffle plate (1002), so that the sliding rod (5012) and the sliding tube (5022) move relative to each other. The rod (5012) moves out of the slide tube (5022), releasing the restriction between the first shell (501) and the second shell (502), and the second shell (502) returns to rotation under the action of the torsion spring (504), so that the second shell (502) moves away from the first shell (501) with the connecting shaft (503) as the center, and a plurality of airbag strips (801) between the first shell (501) and the second shell (502) are expanded, thereby increasing the deployment area of ​​the rescue component (5); When the floating plate (1003) moves, the blocking block (121) is driven to move in the movable groove (12) through the connecting rod (122), and the blocking block (121) no longer blocks the water storage tank (11). Water stored in the water storage tank (11) flows out through the movable groove (12), thereby reducing the self-weight of the rescue component (5); If the first shell (501) and the second shell (502) cannot be separated normally, the staff can also manually push the floating plate (1003) to move, so that the first shell (501) and the second shell (502) are opened, thereby expanding the gripping area of ​​the rescue component (5); S4: The rescuer who swims to the vicinity of the rescue device (5) carries the rescue device (5) whose weight has been reduced and moves to the point where the person falls into the water not far away; If the drowning person is in a lying position with his head up and waiting for rescue or in a half-sunken position, the rescuer holds the rescue device (5) and pulls up the drowning person; If the drowning person is in a struggling posture with both hands raised, the rescuer first places the airbag strip (801) of the rescue unit (5) in front of the drowning person, so that the drowning person can grab the airbag strip (801) or the hanging rope (9) on the airbag strip (801) while randomly grabbing. The rescuer assists in controlling the position of the rescue unit (5) so that the drowning person can grab easily. After the rescuer assists the drowned person to hold the rescue member (5) stably, the remote control switch on the rescue member (5) is controlled to cause the second motor (16) to drive the second reel (162) to rotate via the drive shaft (161), the second reel (162) reels the reeling rope (163), and the rescue member (5) drives the rescuer and the drowned person to move toward the shore as the reeling rope (163) is reeled.
