Description

Technical Field

[0001] This utility model relates to the field of fire rescue equipment technology, and in particular to a multi-functional assault boat. Background Technology

[0002] Inflatable boats are characterized by high speed on water, strong maneuverability, simple operation, large load capacity, and strong adaptability to complex waters in the wild. They are widely used in urban flooding, reservoirs, and water surface scenarios to carry out water search and rescue, water surface rescue, personnel transfer, material transportation, and water surface survey.

[0003] The use of inflatable boats is often constrained by the rescue location, requiring specialized transport vehicles for loading and transportation. Moving them across flooded areas necessitates manual lifting to shore, which is cumbersome, inefficient, and unable to reach complex terrain, resulting in a slow overall response time. While standard inflatable boats are designed to operate in water of a certain depth, existing models generally lack the ability to travel on land, leading to limited manpower and wasted resources. Sometimes, the water depth in disaster areas varies, and in complex environments like rural villages where muddy roads prevent inflatable boats from crossing, making conventional transportation methods cumbersome and inefficient. Navigating in waters that do not meet the inflatable boat's draft requirements poses risks such as grounding and rutting. Inflatable boats cannot pass through shallow or non-flooded areas, severely hindering rescue efficiency. Furthermore, due to their large size and weight, transferring inflatable boats from one rescue area to another takes considerable time, delaying rescue efforts. While ordinary rubber inflatable assault boats are lightweight, they are prone to damage and sinking when encountering sharp or hard objects underwater, causing secondary injuries to rescuers and those being rescued.

[0004] Meanwhile, existing inflatable boats cannot approach complex terrain, hindering the rapid transfer of personnel to the boats. This significantly increases the risk to those being rescued and prevents comprehensive observation of the entire rescue area, reducing rescue efficiency and hindering the effective search for trapped individuals. Therefore, this invention addresses the shortcomings of existing technology by providing a multi-functional inflatable boat that can rapidly transfer personnel to the rescue area and improve rescue efficiency. Summary of the Invention

[0005] To overcome the problems existing in the prior art, the purpose of this utility model is to provide a multi-functional assault boat that is lightweight and can move freely on land and water without auxiliary transport equipment. Equipped with a tracked robot chassis carrying lightweight metal materials, the assault boat can move freely on land and water in muddy village roads or shallow urban waters. The added tracked self-propelled function allows for remote control operation, facilitating rapid deployment from supply depots and quick movement on mudflats for rapid deployment into water areas for emergency rescue. Multiple inflatable airbags are installed in the assault boat's cabin to provide sufficient buoyancy in the water, enabling amphibious use. Furthermore, the addition of an inflatable floating bridge, a flying lifebuoy, and a water rescue robot can significantly improve the speed and efficiency of rescuing and transferring trapped personnel.

[0007] Furthermore, the front of the assault boat is provided with a retractable extension plate, which includes a main plate and a sub-plate; the main plate is fixed to the front end of the assault boat's cabin; the sub-plate is provided with a surrounding plate that can move around the front end of the sub-plate, and the extension plate and the surrounding plate are combined to form the bow section; the main plate, sub-plate, and surrounding plate are connected to the surface of the first airbag; an airbag bottom plate is provided on the bottom surface of the second airbag; a movable connecting plate is provided between the airbag bottom plate and the surrounding plate, one end of the movable connecting plate is movably installed on the surrounding plate and the other end is connected to the airbag bottom plate; the airbag recovery cylinder passes downward through the chassis, the second airbag, and is connected to the airbag bottom plate, and there are two sets of airbag recovery cylinders, located at both ends of the airbag bottom plate respectively.

[0008] Furthermore, the first fixing plate and the second fixing plate are fixed together by a pin assembly, the pin assembly including a pin rod, a sleeve, and a pin stop fixed at the front end of the sleeve; the front end of the pin rod passes through the pin stop and is located inside the sleeve, the front end of the pin rod inside the sleeve is provided with a groove, and a locking bead corresponding to the groove is provided on the sleeve; a spring is provided between the pin rod and the sleeve.

[0009] Furthermore, the powertrain is located in the second compartment and includes an engine, a gearbox, and an electrical control box; the engine is connected to the gearbox; there are two sets of track assemblies, each mounted on both sides of the chassis, with the airbag assembly located on the chassis between the two sets of track assemblies; each track assembly includes a drive sprocket, a driven sprocket, a mounting plate, an upper guide wheel, a lower guide wheel, and a track mounted between the drive sprocket and the driven sprocket; track slats are alternately arranged on the outer surface of the track; the mounting plate is fixed to both sides of the chassis, and the upper and lower guide wheels are mounted on the mounting plate; a synchronous shaft is provided between the driven sprockets; a linkage mechanism is provided between the drive sprockets, and a differential is provided on the linkage mechanism; the differential is connected to the transmission.

[0010] Furthermore, the assault boat cabin is equipped with a propeller and a propeller operating position at the rear, and a foldable control platform is provided on the lifting support rod near the propeller operating position; the assault boat cabin is also equipped with a seat; the powertrain is located in the front of the assault boat cabin; and a handrail connected to the lifting support rod is provided along the upper outer edge of the assault boat cabin.

[0011] Furthermore, the floating bridge is secured by straps between the hooks; the assault boat is also equipped with a water rescue robot suspended from the handrail.

[0012] Furthermore, the control platform is equipped with a handheld remote control.

[0013] The beneficial effects of this utility model are:

[0014] (1) When entering the deep water area, start the air compressor to inflate the airbag assembly. When the airbag assembly is fully inflated, the assault boat will float in the deep water area and can travel in the water. Turn on the propeller on the main body of the assault boat to make the assault boat move forward. At the same time, the track assembly will not stop rotating. The track provides some power to the assault boat by paddling in the water, so that the assault boat can move forward quickly.

[0015] (2) The tracked self-propelled function is added, which can be remotely controlled or manually operated, making it convenient for the assault boat to be quickly mobilized in the disaster area, to move quickly on shallow water and land, and to be quickly deployed to deep water for emergency rescue. The tracked self-propelled speed is 0~3 km / h, and it is equipped with a diesel engine, which solves the problem that the current assault boats are placed in the shore warehouse and need to be transported by trailer during emergency rescue, resulting in slow response speed; and the long-term exposure of the assault boats to wind and sun in the water accelerates their aging.

[0016] (3) The assault boat can move on tracks in shallow waters and mudflats. When it enters waters where it can be navigated normally, it can start the propeller on the assault boat to move forward. It can also use the auxiliary power of the tracks in the water at the same time. The dual power can make it sail stably in the water with a speed of more than 30 km / h. This solves the problem that the assault boat is very easy to run aground due to changes in water level and cannot carry out rescue operations, and the problem that the assault boat is inconvenient to move in complex environments where floods quickly inundate low-lying urban areas and rural villages.

[0017] (4) Fully utilize the engine power of the self-propelled configuration to form a rapid inflation system to realize the function of quickly building a floating bridge. At the same time, it can also carry a variety of water rescue equipment to support the rapid and efficient development of rescue operations. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] like Figure 1-14A multifunctional assault boat as shown includes an assault boat 1, a life-saving equipment platform 2 and a control platform 9 installed on the assault boat 1. An airbag assembly 5 is sealed on the assault boat 1. The assault boat 1 includes an assault boat cabin 3 and a crawler robot chassis 4 installed at the bottom of the assault boat cabin 3. In order to achieve remote unmanned control, the control platform 9 is paired with a handheld remote control (not labeled). The control platform can remotely operate the crawler robot chassis through the handheld remote control (not labeled), or can be manually operated on-site. The multi-directional linkage operation improves the use efficiency. The front and rear parts of the assault boat cabin are streamlined structures, which can reduce the resistance in water. A second cabin 31 is also provided at the bottom inside the assault boat cabin 3; An air compressor 311, a high-pressure gas cylinder 312 and an airbag recovery cylinder 313 connecting the high-pressure gas cylinder 312 are provided inside the second cabin 31; Above the life-saving equipment platform 2, there are a pontoon storage box 21, a flying life buoy 22 and a drone lifting platform 23; Liftable support rods 36 are provided along the upper edge of the assault boat cabin 3, and the life-saving equipment platform 2 is installed on the liftable support rods 36. There are a total of 6 liftable support rods, two at the front, two in the middle and two at the rear, providing stable support for the life-saving equipment platform. At the same time, when the assault boat is traveling at high speed, the two liftable support rods at the front of the assault boat can be lowered by a certain distance, making the front of the life-saving equipment platform lower than the rear, forming a certain inclination angle, providing an upward force for the assault boat when it moves forward, reducing the resistance during movement and lowering the energy consumption; The six liftable support rods can be lowered to reduce the height when there is no disaster relief task, thereby reducing the space occupied during storage; Some uninflated pontoons can be placed in the pontoon storage box and quickly taken out for inflation when needed. There is a drone in the drone lifting platform. The drone can also be used on the assault boat to observe the regional environment and search for trapped people, improving the rescue efficiency. When trapped people in water are found, a life buoy can be remotely controlled and delivered to participate in the rescue through the flying life buoy.

[0038] In this embodiment, as Figure 3 、 Figure 4 、 Figure 7 、 Figure 8A floating bridge support plate 24 is installed below the rescue equipment platform 2, and a floating bridge 25 is placed on the floating bridge support plate 24. The floating bridge support plate 24 has a first fixing plate 241 and multiple hooks 242 on both sides. The floating bridge 25 is secured by straps 251 between the hooks 242 to prevent it from falling during movement. A second fixing plate 26 corresponding to the first fixing plate 241 is provided on the rescue equipment platform 2. The floating bridge support plate is fixed to the rescue equipment platform. To ensure the stability of the floating bridge support plate, the first fixing plate 241 and the second fixing plate 26 are fixed together by a pin assembly 6. The rear end of the floating bridge support plate 24 is fixed to the rescue equipment platform 2 by a movable connector 243. Therefore, the front end of the floating bridge support plate can be lowered at an angle, and the floating bridge can be easily slid down and removed by untying the straps 251. In use, the floating bridge can be erected between the trapped personnel and the inflatable boat. Trapped personnel are transferred to inflatable boats via a lowered pontoon bridge. The pontoon bridge is equipped with a connecting structure (not shown). When one pontoon bridge is insufficient, the movable door (not shown) at the bottom of the corresponding pontoon bridge storage box 21 on the rescue equipment platform 2 can be opened on the inflatable boat to retrieve the pontoon bridge from the storage box. The pontoon bridge can be inflated on-site using an air compressor. Multiple pontoon bridges can be connected in parallel to improve rescue efficiency. The pin assembly 6 includes a pin rod 61, a sleeve 62, and a pin stop block 63 fixed to the front end of the sleeve 62. The front end of the pin rod 61 passes through the pin stop block 63 and is located inside the sleeve 62. The front end of the pin rod 61 inside the sleeve 62 is provided with a groove 64, and the sleeve 62 is provided with a locking bead 65 corresponding to the groove 64. A spring 66 is provided between the pin rod 61 and the sleeve 62. The pin assembly firmly fixes the pontoon bridge support plate to the rescue equipment platform without affecting the forward movement of the inflatable boat.

[0039] In this embodiment, to increase the buoyancy of the inflatable boat in water, the airbag assembly 5 includes a first airbag 51 located at the front of the inflatable boat cabin 3, a second airbag 52 installed at the bottom of the tracked robot chassis 4, and a third airbag 53 installed on both sides of the inflatable boat cabin 3. The first airbag 51, the second airbag 52, and the third airbag 53 are inflated and deflated by an air compressor 311, which is powered by a powertrain 43 to provide compressed air, allowing the airbag assembly to be inflated in a short time. To reduce the resistance of the inflatable boat 1 when moving in water, a retractable flat extension plate 11 is provided at the front of the inflatable boat cabin 3. The extension plate 11 includes a main plate 12 and a... The sub-plate 13 is retractable from the main plate. When the inflatable boat is used in the water, the sub-plate is pulled out and the bulkhead is unfolded. The main plate 12 is fixed to the front end of the inflatable boat cabin 3. The front of the sub-plate 13 is provided with a bulkhead 14 that can move around the front end of the sub-plate 13. The extension plate 11 and the bulkhead 14 are combined to form the bow section. The main plate 12, sub-plate 13, and bulkhead 14 are respectively connected to the surface of the first airbag 51. The bulkhead and the extension plate are independent and are only edge structures that can be adapted after the first airbag is unfolded. The shape of the first airbag is designed with a common streamlined bow shape and adapts to the shape of the extension plate 11 and the bulkhead 14 after combination to reduce the drag of the boat. At the same time, in order to achieve automatic The retractable airbag can be connected to a transverse airbag retraction cylinder (not shown) on the side panel to improve efficiency; the bottom surface of the second airbag 52 is provided with an airbag base plate 521, and a movable connecting plate 141 is provided between the airbag base plate 521 and the side panel 14. One end of the movable connecting plate 141 is movably installed on the side panel 14, and the other end is connected to the airbag base plate 521. In the inflated and deployed state, it can simulate the keel of a common boat, reducing water resistance and improving stability; in order to ensure that the retraction of the airbag does not affect the movement of the assault boat on land, the airbag retraction cylinder 313 passes downward through the chassis 41, the second airbag 52 and the airbag base plate 521. When the airbag is inflated, it is supplied with high-pressure gas cylinder. The airbag recovery cylinder drives the airbag downwards, greatly improving inflation efficiency. The airbag is inflated rapidly by an air compressor. There are two sets of airbag recovery cylinders 313, located at both ends of the airbag base plate 521. When the airbag is not needed to provide buoyancy, the air compressor releases the gas inside the airbag. At the same time, the airbag recovery cylinders, working under the action of the airbag base plate, recover the airbag upwards and squeeze out the excess air inside the airbag, thus realizing the recovery of the airbag. In this embodiment, the air compressor is driven by the engine to achieve inflation. Combined with the attached floating bridge, an amphibious rescue system is formed on the assault boat, enabling the rapid release of rescue equipment from the assault boat, thereby improving rescue efficiency.

[0040] In this embodiment, as Figure 12 , Figure 13 , Figure 14The tracked robot chassis 4 includes a chassis 41, track components 42, and a powertrain 43. The chassis 41 is fixedly connected to the bottom of the assault boat compartment. The powertrain 43 is located in the second compartment 31 and includes an engine 431, a gearbox 432, and an electronic control box 433 for controlling steering during land movement. Power is transmitted to the track components and speed is controlled via a connection between the engine 431 and the gearbox 432. Two sets of track components 42 are provided, located on opposite sides of the chassis 41, including an airbag assembly. Component 5 is located on the chassis 41 between the two sets of track assemblies 42; the track assembly 42 includes a drive wheel 421, a driven wheel 422, a mounting plate 423, an upper guide wheel 424, a lower guide wheel 425, and a track 426 installed between the drive wheel 421 and the driven wheel 422; track strips 4261 are alternately provided on the outer surface of the track 426, which can support the traction of the assault boat on land, and at the same time provide paddling assistance when the assault boat is moving on water. Yes, by utilizing the rotation of the tracks to reduce the resistance between the water and the hull, the water can be quickly transferred from the upper part to the lower part of the tracks, thereby increasing the buoyancy of the assault boat during movement. Combined with the propulsion system, the boat can move forward rapidly with the aid of dual power. The mounting plate 423 is fixed to both sides of the chassis 41, with the upper guide wheel 424 and lower guide wheel 425 respectively installed on the upper and lower parts of the mounting plate 423. A synchronous shaft 427 is provided between the driven wheels 422; a linkage mechanism 428 is provided between the driving wheels 421 to achieve… Turning is achieved using tracks, and a differential 429 is provided on the linkage mechanism. The differential 429 and the gearbox 432 are connected by a double set of gears (not shown). By controlling whether different sets of gears (not shown) are engaged with the gearbox, the drive wheel of one side of the track can be controlled. The linkage mechanism 428 ensures synchronicity when moving forward, and the differential 429 can turn one side of the track while stopping the other side to achieve steering. In order to avoid affecting the installation of the airbag, the linkage mechanism 228 is set on the upper part of the chassis.

[0041] In this embodiment, to enable the inflatable boat to move on the water, a dual thruster 32 is provided at the rear of the inflatable boat cabin 3, and a thruster operation position 33 is provided for easy operation by the user. A foldable control platform 7 is provided on the rear lifting support rod 36 near the thruster operation position 33. The control platform 7 controls the equipment on the inflatable boat, including drones, unmanned lifebuoys, and water rescue robots 8. The control platform 7 can also display images transmitted back by the drones in real time, allowing the operator to control the inflatable boat to reach the location of the stranded personnel based on the search situation of the drones. A seat 34 is also provided in the inflatable boat cabin 3 for the rescued personnel to ride. The power assembly 43 is located at the front of the inflatable boat cabin 3, and the power assembly is set independently from the thrusters, so it does not affect the operation of the rear inflatable boat thrusters. A handrail 35 connected to the lifting support rod 36 is provided on the upper outer edge of the inflatable boat cabin 3 to increase its stability, and the water rescue robot 8 is suspended on the handrail.

[0042] A method of using a multi-functional assault boat includes first transferring the assault boat to a location awaiting rescue via a tracked robot chassis or by using transport equipment;

[0043] 1. When traveling in shallow water and on land: The tracked robot chassis can be controlled by remote control to travel on cement ground, muddy ground and shallow water wading areas. The tracked robot chassis consists of two sets of track components, which are set on both sides of the bottom of the assault boat. When in use, the track drives the boat forward when traveling in shallow water or dry areas. The drive shaft enables the track components to move forward or backward synchronously. When turning is required, the two sets of track components can achieve turning by moving one side through the differential.

[0044] 2. When navigating deep water: When the inflatable boat enters deep water, the buoyancy of the boat's cabin prevents it from sinking. The air compressor is activated to inflate the third airbags installed on both sides of the cabin. Once fully inflated, the boat floats in deep water. The propellers on the main body of the boat are then activated to propel it forward. Simultaneously, the track assembly continues to rotate, providing some power through water propulsion, allowing the boat to move quickly. When the boat is ready for high-speed travel, the air compressor is activated to inflate the first and second airbags installed on both sides of the cabin. Once fully inflated, rapid water skiing is achieved, enabling the inflatable boat to travel at high speeds in deep water.

[0045] 3. During the rescue operation, the drones carried by the assault boats were released to conduct high-altitude exploration of the surrounding area, expanding the rescue scope. The drones were controlled to take off using the control platform next to the assault boat's operating position, and were used to detect the dangers in the disaster area and search for the location of trapped personnel in the high altitude, and the images were transmitted back in real time and displayed on the control platform.

[0046] 4. After locating people stranded on the water via drones from high altitude, the drones will determine their positions. The drones will then be controlled and deployed from the platform to the location of the stranded people, and the lifebuoys will be deployed precisely. At the same time, 8 water rescue robots will be deployed to participate in the rescue.

[0047] 5. Upon arrival at the rescue site, lower the adjustable support rod at the front of the assault boat so that the front of the rescue equipment platform is lower than the rear, forming a certain angle. After reaching the rescue area, release the pontoon support plate, lower the pre-inflated pontoon, drag it to the rescue target location, and connect it to the assault boat to form a transfer channel for the rescued personnel to board the boat. The assault boat is also equipped with a pontoon storage box. When one pontoon is not sufficient for the rescue, the pontoon in the storage box can be taken out and quickly inflated on-site for use, improving rescue efficiency.

[0048] 6. If the inflatable boat encounters shallow water during a rescue operation that prevents it from buoying, the exhaust valve of the second airbag can be opened to quickly depressurize and release the air. The airbag recovery cylinder can then be activated to quickly recover the second airbag, simultaneously compressing it to expel the internal air and return it to its original position, resuming its shallow water travel capability. The boat can then continue its rescue operation on land or in shallow water using its tracks. At the same time, the front first airbag can be manually operated to retract the sub-plate into the main plate and reset the bulkhead. During the retraction process, the air inside the first airbag is also expelled. Once all airbag components have been reset, the boat can travel on land or in shallow water using its tracks, returning to its land travel capability.

[0049] In this embodiment, the inflatable boat of this invention is made of lightweight metal material and is equipped with a tracked robot chassis. It can move freely on land and water in both flooded and non-flooded urban areas, effectively solving the problem that ordinary inflatable boats widely used in emergency rescue are prone to running aground and being unable to carry out rescue operations in complex urban flooding rescue environments due to fluctuating water levels caused by varying road elevations. Furthermore, this invention can inflate the airbag assembly by turning on the air compressor when entering deep water. Once fully inflated, the inflatable boat floats in deep water and can move on the water. The propellers on the main body of the boat are activated to propel it forward, while the track assembly continues to rotate, propelling the boat through the water. This invention provides partial power to propel the inflatable boat forward quickly. Furthermore, by modifying and adding a remote control device (not shown), it enables remotely controlled inflatable boats mounted on a tracked robot chassis, allowing them to move freely on land and water in muddy rural areas. This effectively solves the problem of inflatable boats, currently widely used in emergency rescue, being unable to cross muddy roads in rural villages due to secondary disasters such as mudslides, requiring manual labor that is time-consuming, labor-intensive, and inefficient. Additionally, this invention can be equipped with rescue levers (not shown), throwers (not shown), and other equipment, allowing for the efficient and rapid deployment of various water rescue devices within the multi-functional inflatable boat's space.

[0050] The preferred embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the technical solution of the present utility model is not limited to the above embodiments, nor is it limited to use only in rescue operations. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the technical solution of the present utility model. These changes involve related technologies well known to those skilled in the art, and all of these fall within the protection scope of the present utility model patent.
