Description

Technical Field

[0001] The present invention relates to the technical field of firefighting and rescue equipment, and in particular to a multifunctional assault boat and a method for using the same. Background Art

[0002] Assault boats have the characteristics of fast speed on the water, strong flexibility and maneuverability, simple operation, large load capacity, and strong adaptability to complex outdoor waters. They are widely used in urban flooding, reservoirs, water surfaces and other scenarios to carry out water search and rescue, water surface rescue, personnel transfer, material transportation, water surveys and other tasks.

[0003] When using assault boats, they are often restricted by the rescue site and require special transport vehicles for loading and transportation. When flooding, they need to be manually lifted to the shore, which is troublesome and inefficient. They cannot reach the complex terrain of the shore and have a slow overall response speed. Ordinary assault boats are designed to travel in water of a certain depth, but existing assault boats generally do not have the ability to travel on the ground, resulting in low maneuverability and a large waste of manpower and material resources. Sometimes the depth of accumulated water in the disaster area varies. When encountering the complex environment of rural village rescue, the roads are muddy and the assault boat cannot cross. Ordinary transportation methods are very troublesome and inefficient. Driving in waters that do not meet the draft depth requirements of assault boats has the risk of grounding and beating. Assault boats cannot pass through shallows or non-waterlogged areas, which seriously restricts the efficiency of emergency rescue. In addition, due to the large size and heavy weight of assault boats, it takes a lot of time to move from one rescue area to another, thus delaying rescue. Although ordinary rubber inflatable assault boats are light in weight, they are prone to damage and sinking if they encounter sharp and hard objects underwater, causing secondary injuries to rescuers and rescued people.

[0004] At the same time, existing assault boats cannot get close enough to quickly transfer people to the assault boat when encountering complex terrain, which greatly increases the risk to the rescued people and makes it impossible to fully observe the entire rescue area, reducing rescue efficiency and making it difficult to effectively find trapped people. Therefore, the present invention aims to address the shortcomings of the existing technology and provide a multifunctional assault boat that can quickly transfer to the rescue area and improve rescue efficiency. Summary of the Invention

[0005] In order to overcome the problems existing in the above-mentioned prior art, the purpose of the present invention is to provide a multifunctional assault boat, which is lightweight as a whole and can move and sail freely on land and water without auxiliary carrying equipment. The assault boat is equipped with a crawler robot chassis and a lightweight metal material, which can move and sail freely on land and water in muddy roads in villages or shallow water areas in cities. The crawler self-propelled function is added and can be remotely controlled, which facilitates the rapid mobilization of the assault boat in material depots and the quick movement on mudflats, and can be quickly put into waters for emergency rescue. At the same time, multiple inflatable air bags are arranged on the assault boat cabin to provide sufficient buoyancy for the assault boat in the water, meeting the amphibious use of the assault boat. In addition, the combination of an inflatable floating bridge, a flying lifebuoy and a surface life-saving robot can greatly improve the rescue and transfer speed of trapped people and improve the rescue efficiency.

[0011] Furthermore, the floating bridge is fixed by arranging straps between the hooks; the assault boat is also provided with a water lifesaving robot suspended on the handrail.

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

[0013] A method for using a multifunctional assault boat comprises: firstly, using a crawler robot chassis or transportation equipment to move the assault boat to a rescue location for standby;

[0014] 1. When traveling in shallow water and on land: The crawler robot chassis is controlled by the remote control to travel on cement ground, muddy ground and shallow wading areas. The crawler robot chassis consists of two sets of crawler assemblies, which are installed on both sides of the bottom of the assault boat. When in use, the crawler drives the boat forward when traveling in shallow water or waterless areas, and the drive shaft realizes the synchronous forward or backward movement of the crawler assemblies. When turning is required, the two sets of crawler assemblies achieve unilateral travel to achieve steering through the differential;

[0015] 2. When encountering deep water: When the assault boat enters the deep water, the buoyancy of the assault boat cabin can support the assault boat from sinking. Start the air compressor to inflate the third airbag installed on both sides of the assault boat cabin. When the third airbag is fully inflated, the assault boat floats in the deep 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 does not stop rotating. The track provides part of the power for the assault boat by paddling in the water, making the assault boat move forward quickly. When the assault boat has high-speed conditions, start the air compressor to inflate the first and second airbags installed on both sides of the assault boat cabin. When the first and second airbags are fully inflated, the rapid water skiing function is realized, so that the assault boat can travel at high speed in deep water.

[0016] 3. During the rescue process, the drone carried by the assault boat is released to conduct high-altitude exploration of the surrounding area to expand the rescue scope. The control platform next to the assault boat's operating position is used to control the drone to take off, detect the dangerous situation in the disaster area and search for the location of trapped people at high altitude, and transmit images in real time for display on the control platform;

[0017] 4. After the UAV finds the trapped person on the water from high altitude, determines the location, and then controls and releases the unmanned lifebuoy from the control platform to fly to the location of the trapped person, and accurately implements the deployment of the lifebuoy;

[0018] 5. When arriving at the rescue site, lower the liftable support rod on the front of the assault boat so that the front of the lifesaving equipment platform is lower than the rear, forming a certain angle. After arriving at the rescue area, release the pontoon support plate, lower the pre-inflated pontoon, drag it to the rescue target location and connect the assault boat to form a transfer channel for the rescued people to board the boat. There is also a pontoon storage box on the assault boat. When one pontoon is not enough for the rescue, the pontoon in the pontoon storage box can be taken out and quickly inflated on site to improve the rescue efficiency.

[0019] 6. If the rescue boat encounters shallow water again and cannot float, the exhaust valve of the second airbag can be opened to quickly relieve the pressure and exhaust the air in the second airbag. The airbag recovery cylinder can be started to quickly recover the second airbag, and at the same time, the airbag can be compressed to quickly discharge the internal air. The airbag can be retracted to its original position, and the boat can return to the shallow water state. The boat can continue the rescue on land or in shallow water by using the tracks. At the same time, the auxiliary plate of the first airbag in the front can be manually retracted into the main plate, and the coaming can be reset. During the retraction process, the air in the first airbag can be discharged. After the reset work of the airbag assembly is completed, the boat can use the tracks to travel on land or in shallow water and return to the land state.

[0020] Beneficial effects of the present invention:

[0021] (1) When entering deep water, start the air compressor to inflate the airbag assembly. When the airbag assembly is fully inflated, the assault boat floats in the deep water 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 does not stop rotating. The track provides part of the power for the assault boat by paddling in the water, making the assault boat move forward quickly.

[0022] (2) Add a crawler self-propelled function, which can be remotely controlled or manually operated, making it easy to quickly mobilize the assault boat in the disaster area, realize quick travel in shallow water and land, and quickly deploy it in deep water for emergency rescue. The crawler self-propelled speed is 0~3 kilometers per hour, and it is equipped with a diesel engine. This solves the current pain points of the assault boat being placed in a warehouse on the shore and needing to be towed for transportation during emergency rescue, which is slow to respond; and the pain points of the assault boat being placed in the water for a long time and being exposed to wind and sun, which accelerates the aging of the assault boat;

[0023] (3) The assault boat can move on tracks in shallows, mudflats and other areas. When entering waters where normal navigation is possible, the propeller on the assault boat can be activated to move forward. The auxiliary power of the tracks in the water can also be used at the same time. The dual power can sail stably in the water at a speed of more than 30 kilometers per hour, solving the problem that the assault boat is easily stranded and unable to carry out rescue operations due to changes in water levels, and the difficulty of the assault boat to move in the complex environment of rescue in low-lying areas of cities and rural villages when floods quickly submerge them;

[0024] (4) The engine power of the self-propelled function is fully utilized to form a rapid inflation system to realize the rapid construction of a pontoon bridge. At the same time, it can also carry a variety of water rescue equipment to support the rapid and efficient implementation of rescue operations. BRIEF DESCRIPTION OF THE DRAWINGS

The track provides part of the power for the assault boat by paddling in the water, making the assault boat move forward quickly. When the assault boat has high-speed conditions, start the air compressor to inflate the first and second airbags installed on both sides of the assault boat cabin. When the first and second airbags are fully inflated, the rapid water skiing function is realized, so that the assault boat can travel at high speed in deep water.

[0052] 3. During the rescue process, the drone carried by the assault boat is released to conduct high-altitude exploration of the surrounding area to expand the rescue scope. The control platform next to the assault boat's operating position is used to control the drone to take off, detect the dangerous situation in the disaster area and search for the location of trapped people at high altitude, and transmit images in real time for display on the control platform;

[0053] 4. After the UAV finds the trapped person on the water from a high altitude, it determines the location, then controls and releases the unmanned lifebuoy from the control platform to fly to the location of the trapped person, accurately implements the release of the lifebuoy, and simultaneously releases the surface lifesaving robot 8 to participate in the rescue;

[0054] 5. When arriving at the rescue site, lower the liftable support rod on the front of the assault boat so that the front of the lifesaving equipment platform is lower than the rear, forming a certain angle. After arriving at the rescue area, release the pontoon support plate, lower the pre-inflated pontoon, drag it to the rescue target location and connect the assault boat to form a transfer channel for the rescued people to board the boat. There is also a pontoon storage box on the assault boat. When one pontoon is not enough for the rescue, the pontoon in the pontoon storage box can be taken out and quickly inflated on site to improve the rescue efficiency.

[0055] 6. If the rescue boat encounters shallow water again and cannot float, the exhaust valve of the second airbag can be opened to quickly relieve the pressure and exhaust the air in the second airbag. The airbag recovery cylinder can be started to quickly recover the second airbag, and at the same time, the airbag can be compressed to quickly discharge the internal air. The airbag can be retracted to its original position, and the boat can return to the shallow water state. The boat can continue the rescue on land or in shallow water by using the tracks. At the same time, the auxiliary plate of the first airbag in the front can be manually retracted into the main plate, and the coaming can be reset. During the retraction process, the air in the first airbag can be discharged. After the reset work of the airbag assembly is completed, the boat can use the tracks to travel on land or in shallow water and return to the land state.

Since the urban water level changes at any time due to the different road elevations, the assault boat is very likely to run aground and cannot carry out rescue operations; the present invention can also turn on the air compressor to inflate the airbag assembly when entering the deep water area. When the airbag assembly is fully inflated, the assault boat floats in the deep water area and can travel in the water. The propeller on the assault boat body is turned on to make the assault boat move forward, and at the same time the crawler assembly does not stop rotating, and the crawler propels the assault boat in the water by paddling. Provide part of the power to make the assault boat move forward quickly; the present invention can also be modified to add a remote control device (not marked) to achieve a remote-controlled crawler robot chassis equipped with a lightweight metal assault boat, so that it can walk and sail freely on land and on water in muddy areas of rural villages, effectively solving the problem that the inflatable assault boats currently widely used in emergency rescue are faced with the complex environment of rural village rescue. Since rural villages are accompanied by secondary disasters such as mudslides, the roads are muddy and the assault boat cannot cross. It is time-consuming and labor-intensive to lift them by manpower, and the rescue efficiency is low; at the same time, the present invention can also be equipped with life-saving pull rods (not marked), throwers (not marked) and other equipment, and the multifunctional assault boat can fully and reasonably use the space to carry a variety of water rescue equipment to support the rapid and efficient implementation of rescue operations.

[0057] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the technical solution of the present invention is not limited to the above-mentioned embodiments, nor is it limited to use only for rescue. Within the scope of knowledge possessed by ordinary technicians in this field, various changes can be made without departing from the technical solution of the present invention. These changes involve related technologies well known to those skilled in the art, and all fall within the scope of protection of the patent of the present invention.
