[0001] The present invention relates to the technical field of rescue equipment, and in particular to a remote-controlled firefighting and rescue equipment on water. Background Art

[0002] In the process of searching and rescuing drowning people on the surface of natural lakes or oceans, the traditional rescue method mainly relies on rescuers to approach with life-saving equipment. The rescue process is difficult, requires high physical endurance of lifeguards, and is also dangerous. In order to reduce the workload and risk factor of rescuers, large fireboats are currently used for water firefighting and rescue at home and abroad. This type of firefighting equipment is large in size, slow in speed, expensive, and requires a dedicated dock to dock, which greatly limits the efficiency and popularity of firefighting and rescue. Summary of the invention

[0003] Based on this, the purpose of the present invention is to provide an on-water remote-controlled firefighting and rescue equipment, which is small in size and can carry out rescue work while extinguishing fires, thereby improving rescue efficiency.

[0029] See also Figure 1 and Figure 2 , an on-water remote-controlled firefighting and rescue device provided in one embodiment of the present invention comprises a rescue body 10, and a lifting bracket 11 and an automatic firefighting cannon 12 fixed on the rescue body 10;

[0030] A water inlet and a water outlet are provided at the bottom of the rear end of the rescue body 10, the water inlet is connected to the first interface of the water outlet divider 13, the water outlet is connected to the second interface of the water outlet divider 13, the third interface of the water outlet divider 13 is connected to the automatic fire monitor 12 through a fire hose 14, and a jet propeller 15 is provided in the water inlet;

[0031] The lifting bracket 11 is provided with a rescue and scavenging component 16. When performing a rescue, the scavenging portion of the rescue and scavenging component 16 extends out of the front end of the rescue body 10 and rotates downward to just below the person who falls into the water, and then performs reverse actions in sequence to rescue the person who falls into the water into the rescue body 10.

[0032] It should be noted that in the present invention, since the rescue main body 10 is an amphibious fire rescue boat, a motorized fire rescue boat or a fire rescue hovercraft, it does not need to be substantially modified, so that the water remote control rescue equipment is small in size and fast in speed, and can be used for both water and land fire fighting and water emergency rescue. In addition, the jet propulsion 15 of the rescue main body 10 itself is used as a fire pump, simplifying the structure of the fire extinguishing rescue boat.

[0033] See also Figure 1 and Figure 2 The rescue and scavenging component 16 is symmetrically arranged at the front end of the rescue body 10, including two lifting cylinders 161 rotatably connected to the top of the lifting bracket 11, two telescopic cylinders 162 rotatably connected to the rescue body 10, and a supporting net 163 (i.e., the scavenging part) connected to the extended ends of the two telescopic cylinders 162. The extended end of the lifting cylinder 161 is rotatably connected to the cylinder body shell of the extended head end of the telescopic cylinder 162.

[0034] It should be noted that when carrying out rescue, the extending ends of the two telescopic cylinders 162 extend toward the front end of the rescue body 10 so that the supporting net 163 extends out of the front end of the rescue body 10, and then the extending ends of the two lifting cylinders 161 extend downward so that the extending ends of the two telescopic cylinders 162 rotate downward, that is, the supporting net 163 extends to directly below the person who falls into the water; then the extending ends of the two lifting cylinders 161 are retracted upward so that the extending ends of the two telescopic cylinders 162 rotate upward to a horizontal position, that is, the supporting net 163 extends to rescue the person who falls into the water from the water, and the extending ends of the two telescopic cylinders 162 are retracted toward the direction of the rescue body 10 to rescue the person who falls into the water into the rescue body 10.

[0035] See also Figure 1 and Figure 2, in a preferred embodiment of the present invention, a U-shaped rod 164 is connected between the extended ends of the two telescopic cylinders 162, and the side wall of the U-shaped rod 164 is connected to the supporting net 163. During the rescue process, the U-shaped rod 164 is used to keep the actions of the two telescopic cylinders 162 synchronized and consistent, and at the same time prevent the outside of the supporting net 163 from sinking, which may affect the rescue.

[0036] Furthermore, the included angle between the U-shaped rod 164 and the extended ends of the telescopic cylinders 162 is an obtuse angle. During the rescue process, the U-shaped rod 164 blocks the drowning person to prevent the drowning person from slipping into the water again.

[0037] Please refer to Figure 1 and Figure 2 , in another preferred embodiment of the present invention, the lifting bracket 11 includes a support frame 111 provided on the rescue main body 10, and two connecting frames 112 provided on the support frame 111. Each connecting frame 112 is connected to the supporting net 163 through a connecting rope 17 to prevent the inside of the supporting net 163 from sinking, which may affect the rescue.

[0038] Preferably, the connecting rope 17 is in a W shape between the supporting net 163 and the support frame 111 to enhance the connection stability.

[0039] Please refer to Figure 1 and Figure 2 , in a preferred embodiment of the present invention, a flow control valve 18 is provided between the third interface of the water outlet diverter 13 and the automatic fire monitor 12, and the flow control valve 18 is used to control the water spray flow of the automatic fire monitor 12.

[0040] Please refer to Figure 1 and Figure 2 , in another preferred embodiment of the present invention, a rear spray throttle valve 19 is connected between the second interface of the water outlet diverter 13 and the water outlet, and the rear spray throttle valve 19 is used to control the water outlet flow of the water outlet.

[0041] Please refer to Figure 1 and Figure 2 , in this embodiment, when the waterborne remote-controlled fire rescue equipment is an amphibious fire rescue boat, the automatic fire monitor 12 is located on one side of the rear end of the rescue main body 10, a pressurized inlet pipe 20 is provided at the water inlet, and a direction control mechanism 21 is provided at the rear spray throttle valve 19 to control the traveling direction of the waterborne remote-controlled fire rescue equipment through the direction control mechanism 21.

[0042] It should be noted that during the use of this embodiment:

[0043] If the current task is to extinguish a fire in waters, the rescue body 10 is driven within 100 meters of the burning hull, and the driver operates the thrower to throw the anchor chain toward the burning hull to connect the rescue body 10 to the burning hull to fix the rescue body 10, thereby eliminating the reaction force of the recoil generated by the high-pressure water flow ejected by the automatic fire cannon 12 on the rescue body 10 during fire extinguishing. During the fire extinguishing process, the flow control valve 18 of the automatic fire cannon 12 is opened, the rear spray throttle valve 19 is closed, the engine speed is increased to make the jet propulsion 15 supply water to the fireboat with high power, the height and direction of the automatic fire cannon 12 are adjusted, and water is sprayed to the fire source to extinguish the fire. At this time, the reaction force of the recoil generated by the high-pressure water flow ejected by the automatic fire cannon 12 on the rescue body 10 can also be eliminated by opening the rear spray throttle valve 19 and adjusting the direction control mechanism 21 at the same time, thereby solving the problem of the stability of the rescue body 10, thereby achieving the purpose of the small boat being able to spray water to extinguish the fire;

[0044] If the current task is to extinguish a fire on land, the pressurized water inlet pipe 20 is inserted into the water inlet slot of the jet propulsion device 15 to seal the water inlet, and then the pressurized water inlet pipe 20 is connected to the municipal fire hydrant, the municipal water flow is connected, and the jet propulsion device 15 and the automatic fire monitor 12 are started to extinguish the fire;

[0045] If the current task is to rescue people in a water area, if the water flow is still or the flow rate is low, the rescue body 10 can approach the person who falls into the water from any direction, operate the rescue catching component 16 to lower the supporting net 163, and slowly approach the person who falls into the water until the entire body of the person who falls into the water enters the supporting net 163, then operate the rescue catching component 16 to lift the person who falls into the water out of the water to complete the rescue task; if the flow rate of the water area is high, drive the rescue body 10 to the downstream of the person who falls into the water, operate the rescue catching component 16 to lower the supporting net 163 and drive towards the direction of the person who falls into the water until the entire body of the person who falls into the water enters the supporting net 163, then operate the rescue catching component 16 to lift the supporting net 163 to complete the rescue.

[0046] When used as a floating pump, the rescue body 10 is driven into a lake or pond, and a fire hose is connected from the outlet of the automatic fire monitor 12, and water can be supplied to the land according to the operation method for extinguishing a fire in a water area.

[0047] See also Figure 3 and Figure 4 In a preferred embodiment of the present invention, when the water remote-controlled firefighting and rescue equipment is a motorized firefighting and rescue boat, the automatic fire cannon 12 is located on one side of the middle part of the rescue body 10, and a direction control mechanism 21 is provided at the rear spray throttle valve 19.

[0048] See also Figure 5 and Figure 6In another preferred embodiment of the present invention, when the water remote-controlled firefighting and rescue equipment is a firefighting and rescue hovercraft, the automatic fire cannon 12 is located in the middle of the front end of the rescue body 10, the jet propulsion unit 15 is connected to the engine 23 at the rear of the rescue body 10 through a transfer case 22, and a direction control mechanism 21 is provided at the rear spray throttle valve 19.

[0049] It should be noted that in this embodiment, by adding a jet propulsion device 15 (i.e., a jet pump) that matches the engine power, a direction control mechanism 21, and a transfer case 22 to the rear of the hovercraft, the modification of the water remote control firefighting and rescue equipment can be completed. When necessary, the power of the engine 23 can be transferred to the jet propulsion device 15. The hovercraft propulsion system is still used during normal driving, which can maintain the characteristics of the hovercraft with a wide range of applications and high speed. When extinguishing a fire, the power of the hovercraft is connected to the jet propulsion device 15 through the transfer case 22, and the hull is fixed and the water is discharged to extinguish the fire according to the operating method of the amphibious firefighting and rescue ship.

[0050] In summary, in the water remote-controlled firefighting and rescue equipment described in the present invention, since the rescue body 10 is an amphibious firefighting and rescue ship, a motorized firefighting and rescue boat or a firefighting and rescue hovercraft, no major modification is required, so that the water remote-controlled rescue equipment is small in size and fast in speed. It can be used for firefighting in waters and on land, for emergency rescue in waters, and can also be used as a floating boat pump to supply water to land fire trucks in rivers, lakes and seas. It is moderately priced and has a wide range of applications. It can be configured at special docks as well as at professional and township fire stations.

[0051] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
