Description

Technical Field

[0001] The present invention relates to the technical field of unmanned boats, and in particular to a new type of high-performance patrol and search and rescue unmanned boat. Background Art

[0002] In recent years, with the gradual expansion of the scope of navigation, improving the safety of the sea area and responding to sudden situations in advance, maritime patrol missions are indispensable. Current patrol boats usually need to be driven by personnel when performing missions, which consumes a certain amount of manpower and material resources. In addition, there is a risk of casualties when performing missions in unsafe waters. Unmanned boats are particularly important in naval battles due to their small size, unmanned operation and fast action. However, in the process of patrolling using unmanned patrol boats, there are problems such as poor stability, difficulty in positioning their position and limited endurance.

[0003] As the boat moves, the bow exerts pressure on the water, splitting it and pushing it forward. This creates a set of waves that follow the boat forward, known as bow waves. As the stern of the boat moves forward, it creates a low-pressure area in the water, forming a trough, which in turn creates a set of waves generated by the stern, known as wake waves. Because the boat's hull generates bow and wake waves, which require energy, this creates wave-making resistance, which in turn creates a certain amount of resistance for the patrol boat.

[0004] A multi-agent system is a collection of multiple agents that expresses its structure, functionality, and behavioral characteristics through communication, collaboration, mutual understanding, coordination, scheduling, management, and control among the agents. Solving practical problems with a multi-agent system offers strong robustness, reliability, and high problem-solving efficiency.

[0005] However, the main defects of existing single-body unmanned boats are poor stability and relatively simple working adjustment capabilities, which cannot meet the various mission requirements of patrolling sea areas. Summary of the Invention

[0006] The purpose of the present invention is to provide a patrol and rescue unmanned boat with high stability and multiple working functions.

[0007] The technical solution of the present invention is: providing a new type of high-performance patrol and rescue unmanned boat, the unmanned boat comprising: an upper hull, a lower hull and a load equipment bracket;

[0008] The upper hull is a prism structure with two ventilation holes on the rear slope of the upper hull. The front end of the lower hull is pointed and the rear end is square. The edges of the upper and lower hulls are rounded. The bottom of the lower hull is equipped with six drag-reducing curved surfaces. The payload equipment bracket is installed at the rear of the upper hull and is tilted toward the rear of the unmanned boat.

[0009] The lower hull compartment is divided into two parts by a watertight baffle, the front part is the control equipment compartment, and the rear part is the power equipment compartment; two heat dissipation holes are set on the upper part of the watertight baffle, and the heat dissipation holes are connected to the ventilation holes.

[0010] In any of the above technical solutions, further, the heat dissipation holes are located inside the unmanned boat, and a turbofan is installed in each heat dissipation hole. At the same time, the two turbofans are in different working states, including suction and blowing. The turbofans form convection ventilation and heat dissipation inside the control equipment compartment; the power equipment compartment includes batteries, gasoline engines, cooling pipes and air intake pipes, and the heat dissipation holes are respectively connected to the cooling pipes and the air intake pipes to dissipate heat for the batteries and gasoline engines.

[0011] In any of the above technical solutions, further, the ventilation hole includes: a ventilation channel, an electric ball valve and a rotating table, the connection between the rotating table and the surface of the unmanned boat is sealed, the ventilation channel is connected to the heat dissipation hole, the electric ball valve is installed on the ventilation channel, the electric ball valve closes the ventilation channel when working, and the ventilation port of the rotating table rotates around the center of the rotating table as the axis.

[0013] When the unmanned boat detects that the heel angle is greater than a first preset value, the vents of the vents close to the heel direction face the heel direction, and the turbofans inside these vents work in a blowing state. The vents of the vents away from the heel direction face the opposite direction of the heel direction, and the turbofans inside these vents work in a suction state, applying a force opposite to the heel direction to stabilize the unmanned boat.

[0014] When the unmanned boat detects that the heel angle is greater than a second preset value, the two turbofans stop working and the electric ball valve shuts off the ventilation channel to prevent water from entering;

[0015] The second preset value is greater than the first preset value.

[0016] In any of the above technical solutions, further, a microwave antenna, a G / G antenna, a laser radar, a rear camera, an electromagnetic switch, rescue equipment, a multi-degree-of-freedom rotation positioning body and an ejection cylinder are arranged on the payload equipment bracket;

The rescue equipment is connected to the ejection cylinder at the same time, and the ejection cylinder is fixed on the multi-degree-of-freedom rotation positioning body.

[0018] In any of the above technical solutions, further, the unmanned boat obtains its own position coordinates through GPS positioning, and the unmanned boat receives a signal sent by the remote control device to obtain the position coordinates of the remote control device, thereby calculating the distance between itself and the shore-based control console or the handheld wireless remote control;

[0019] Remote control equipment includes: shore-based control console and handheld wireless remote control;

[0020] When the distance between the remote control device and the unmanned boat is within ten kilometers, the unmanned boat uses a microwave antenna to communicate using a short-delay digital radio mode path for control data; when the distance between the remote control device and the unmanned boat is greater than ten kilometers, the unmanned boat uses a 4G / 5G mode path to communicate through a 4G / 5G antenna that can ensure the reliability of long-distance data transmission, ensuring the reliability of long-distance data transmission.

[0022] In any of the above technical solutions, further, the user specifies the route of the unmanned boat through the remote control device, which is a broken line or an arc, and continuously sends control signals to the unmanned boat. The unmanned boat navigates according to the control signals and continuously sends its own position signals to the remote control device to correct the route.

[0023] In any of the above technical solutions, further, when the unmanned boat is relatively close to the object to be rescued, the rear camera (14) rotates to scan the position where the object to be rescued sends a distress signal to obtain an image, extract feature parameters of the image, and calculate the relative position and direction of the unmanned boat and the object to be rescued;

[0026] The beneficial effects of the present invention are:

[0027] The technical solution of this invention adopts a low-resistance unmanned boat surface design. The upper hull adopts a stepped shape, and the lower hull adopts a wave-breaking shape with a pointed front and a square tail. Six drag-reducing curved surfaces are also designed on the bottom of the unmanned boat. The coating adopts a drag-reducing paint coating composed of silicone gel, silicone rubber and polyethylene film.

The rotatable ventilation holes can also adjust the boat's posture by controlling the windward side.

DETAILED DESCRIPTION

[0041] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present invention and the features therein can be combined with each other without conflict.

[0042] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0043] like Figures 1 to 2 As shown, this embodiment provides a new type of high-performance patrol and search and rescue unmanned boat, which includes: an upper hull 100, a lower hull 200 and a load equipment bracket 9.

[0044] Specifically, the upper hull 100 is a prism structure, and the upper hull 100 is divided into three areas according to the edges: the upper bow 101, the upper midship 102 and the upper stern 103. The lower hull 200 is divided into three areas according to the partition of the upper hull 100: the lower bow 201, the lower midship 202 and the lower stern 203. The connection transitions between each part are all rounded; the load equipment bracket 9 is installed on the upper stern 103, and the load equipment bracket 9 is inclined toward the rear of the unmanned boat. The load equipment bracket 9 is a hollow design, which reduces weight while reducing air resistance; six drag-reducing curved surfaces are set on the bottom of the lower hull 200.

[0045] The lower bow 201 is pointed, and the lower stern 203 is square. This boat design is conducive to breaking waves and can greatly improve the speed of the boat. The width reaches its maximum at about 35% of the hull length from the lower bow 201 to the lower midship 202, and the width from the lower midship 202 to the lower stern 203 remains unchanged.

[0046] The entire boat is coated with a drag-reducing paint coating, which is composed of silicone gel, silicone rubber and polyethylene film. As the ship's speed increases, the drag reduction advantage will become more obvious. Under optimal conditions, the total resistance of the coating will be reduced by 3%.

[0047] like Figures 3 and 4 As shown, a cross cable bollard 1 is provided at the middle of the front end of the upper bow 101 for mooring, and a maintenance watertight door 6 is installed on the front face of the upper bow 101, and an oil filling hole 2 and a charging hole 20 are provided on both sides of the maintenance watertight door 6.

[0048] A loudspeaker 3, a navigation antenna 4 and a searchlight 19 are provided at the top of the upper midship part 102, and a main switch 18 is provided on the side wall of the upper midship part 102 for controlling the start of the unmanned boat.

[0049] A cross cable pile 1 is also provided on both sides of the tail end of the upper stern part 103, and a maintenance watertight door 6 is also installed on the rear face of the upper stern part 103. Two ventilation holes 5 are installed on the inclined surface above the maintenance watertight door 6. Since the ventilation holes 5 are installed on the rear inclined surface of the unmanned boat, the possibility of seawater entering the cabin through the ventilation holes 5 is greatly reduced.

[0050] A jet pump 45 is installed at the bottom of the stern of the unmanned boat. The jet pump 45 can rotate according to the direction of the boat's forward movement. Compared with the traditional propeller and rudder propulsion method, the direction of the propulsion force can be adjusted more freely and quickly, thereby improving the maneuverability of the boat and reducing the impact on the environment.

[0051] The sidelights 7 are installed on the outer contour of the load equipment bracket 9, which can effectively mark the width of the outer contour of the hull; polyurethane anti-collision blocks are installed on the outside of the bracket to prevent collision damage to the bracket and the load equipment on it when mooring.

[0052] In this embodiment, the payload equipment bracket 9 is provided with a sidelight 7, a microwave antenna 8, a night vision device 10, a 4G / 5G antenna 11, a laser radar 12, a controller antenna 13, a rear camera 14, a warning light 15, an electromagnetic switch 16, and rescue equipment 17. The electromagnetic switch 16 is installed above the rescue equipment 17 to fix the rescue equipment 17. When the electromagnetic switch 16 is turned on, the rescue equipment 17 is released into the sea for use by the rescue target. Figure 7 As shown, the rescue equipment 17 is also connected to the ejection cylinder 47, and the ejection cylinder 47 is fixed on the multi-degree-of-freedom rotating positioning body 46 installed on the stern part 103 of the upper boat. When the unmanned boat is relatively close to the object to be rescued, the rear camera 14 rotates to scan the position where the object to be rescued sends a distress signal to obtain an image, extract the characteristic parameters of the image, calculate the relative position and direction of the unmanned boat and the object to be rescued, and then prepare to launch the rescue equipment 17. First, turn on the electromagnetic switch 16 to release the rescue equipment 17, then the multi-degree-of-freedom rotating positioning body 46 adjusts the angle of the ejection cylinder 47, and the ejection cylinder 47 adjusts the force to accurately eject the rescue equipment 17 to the object to be rescued.

[0053] In this embodiment, the rear camera 14 obtains images and extracts image feature parameters using existing target detection technology. The target detection technology can use computer vision technology such as SIFT, SURF and ORB algorithms, or it can use convolutional neural network processing to match the data in the database, determine the target and obtain the specific position of the target, and calculate the relative position and direction of the unmanned boat and the target in combination with the rotation angle of the rear camera 14.

[0054] The load equipment bracket 9 and each device it carries are connected with vibration isolation and damping pads, which can effectively reduce the vibration of the equipment; the load equipment bracket 9 can be equipped with corresponding equipment at any time according to the different functions to be realized.

[0055] In this embodiment, when the unmanned boat needs to dock, it tracks the docking position through the laser radar 12 and the rear camera 14. The rear camera 14 rotates to scan the sea and sky area image, and uses the above-mentioned method to extract the characteristic parameters of the sea and sky area image and compare them with the characteristic parameters of the template image used for calibration to confirm the docking position area, and calculate the relative position, direction and heading of the unmanned boat and the docking position area; after confirming the docking position area, the laser radar 12 will scan in the direction of the docking position area to obtain the radar image. During the docking process, the laser radar 12 tracks the docking position area so that it is always located in the center of the radar image.

[0056] like Figures 5 and 6As shown, the lower hull 200 is divided into two parts by a water-proof baffle 35, the front part is the control equipment compartment, and the rear part is the power equipment compartment; the equipment in the compartment is arranged as symmetrically as possible according to the weight of a single control device to ensure the lateral stability of the hull; the sides and bottom of the cabin are covered with foam material, and if an overturning accident occurs, it can ensure that the unmanned boat still has a certain buoyancy to float on the water surface, ensuring that the rescue ship can find it in the first time.

[0057] In this embodiment, the control equipment compartment is provided with a first bracket 22, a second bracket 24, a third bracket 26 and a fourth bracket 27 from front to back; the first bracket 22 is equipped with a coulomb meter 21, a throttle pump control box 43 and a dump bucket control box 44; the second bracket 24 is equipped with a hard disk recorder 23, an industrial computer 41 and a combined navigation module 42, and the industrial computer 41 is responsible for receiving external command signals; the third bracket 26 is equipped with an intelligent main control box 25, a 4G communication module 39 and a distribution box 40; the fourth bracket 27 is equipped with a remote control receiving box 28, a switch 36, a tachometer module 37 and a charger 38.

[0058] In this embodiment, the power equipment compartment is equipped with a battery 29 , a gasoline engine 30 , a cooling pipeline 31 , an air intake pipeline 32 , a transmission shaft system 33 and a pipeline assembly 34 .

[0059] In addition, two groups of heat dissipation holes are designed on the upper part of the water-blocking baffle 35, and the heat dissipation holes are connected to the ventilation holes 5. A turbofan is installed in each heat dissipation hole. At the same time, the two turbofans are in different working states, including suction and blowing, thereby forming an air flow channel inside the control equipment compartment for ventilation and heat dissipation; the cooling pipe 31 and the air intake pipe 32 are connected to the heat dissipation holes to dissipate heat for the power equipment compartment.

[0060] like Figure 8 As shown, the ventilation hole 5 includes: a ventilation channel 501, an electric ball valve 502 and a rotating platform 503. The connection between the rotating platform 503 and the surface of the unmanned boat is sealed, the ventilation channel 501 is connected to the heat dissipation hole, and the electric ball valve 502 is installed on the ventilation channel 501. When the electric ball valve 502 is working, the ventilation channel 501 is closed, and the ventilation port of the rotating platform 503 rotates around the center of the rotating platform 503.

[0061] The ventilation hole 5 has an anti-rollover function, and the method for realizing the anti-rollover function includes:

[0062] When the unmanned boat detects that the heel angle is greater than the first preset value, the vents of the ventilation holes 5 close to the heel direction face the heel direction, and the turbofan inside this ventilation hole 5 works in a blowing state. The vents of the ventilation holes 5 away from the heel direction face the opposite direction of the heel direction, and the turbofan inside this ventilation hole 5 works in a suction state, giving the unmanned boat a force opposite to the heel direction to stabilize it.

[0063] When the unmanned boat detects that the heel angle is greater than a second preset value, the two turbofans stop working, and the electric ball valve 502 works to close the ventilation channel 501 to prevent water from entering; wherein, the second preset value is greater than the first preset value.

[0064] The unmanned boat of this embodiment obtains its own position coordinates through GPS positioning. The unmanned boat receives the signal sent by the shore-based control console or the handheld wireless remote control to obtain the position coordinates of the shore-based control console or the handheld wireless remote control, thereby calculating the distance between itself and the shore-based control console or the handheld wireless remote control. When the distance is within ten kilometers, the unmanned boat adopts the digital radio mode path communication, which can effectively reduce the control data delay characteristics and improve the real-time operation; when the distance is greater than ten kilometers, the 4G / 5G mode path communication is selected to ensure the reliability of long-distance data transmission.

[0065] After the user specifies the target position or route using a remote control device such as a shore-based control console or a handheld wireless remote control, the unmanned boat of this embodiment communicates with the remote control device to perform corresponding movement operations, specifically including: when the user specifies the target position, the remote control device sends a target position signal to the unmanned boat, and after the unmanned boat receives the signal through the industrial computer 41, it plans the route and navigates by itself through the navigation-related equipment carried by the unmanned boat; when the user specifies the route of the unmanned boat, the remote control device maintains communication with the unmanned boat to obtain the real-time position of the unmanned boat, and based on the real-time position of the unmanned boat corresponding to the position on the route specified by the user, determines the direction to move at the current moment to avoid deviation, and the remote control device sends a direction signal to the unmanned boat.

[0066] In summary, the present invention proposes a new type of high-performance patrol and search and rescue unmanned boat, including: an upper hull 100, a lower hull 200 and a load equipment bracket 9.

[0067] The upper hull 100 is a prism structure, with two ventilation holes 5 set on the inclined surface at the rear of the upper hull 100. The front end of the lower hull 200 is pointed and the tail end is square. Six drag-reducing curved surfaces are set on the bottom of the boat. The load equipment bracket 9 is installed at the tail of the upper hull 100, and the load equipment bracket 9 is inclined toward the rear of the unmanned boat.

[0068] The cabin of the lower hull 200 is divided into two parts by a water-proof baffle 35, the front part is the control equipment cabin, and the rear part is the power equipment cabin; two heat dissipation holes are set on the upper part of the water-proof baffle 35, and the heat dissipation holes are connected to the ventilation holes 5. The heat dissipation holes are located inside the unmanned boat. A turbofan is installed in each heat dissipation hole. The two turbofans are in different working states, including suction and blowing, forming convection ventilation and heat dissipation inside the control equipment cabin; the power equipment cabin includes a battery 29, a gasoline engine 30, a cooling pipe 31 and an air intake pipe 32, and the heat dissipation holes are respectively connected to the cooling pipe 31 and the air intake pipe 32 to dissipate heat for the battery 29 and the gasoline engine 30.

[0069] The ventilation hole 5 includes: a ventilation channel 501, an electric ball valve 502 and a rotating platform 503. The connection between the rotating platform 503 and the surface of the unmanned boat is sealed. The ventilation channel 501 is connected to the heat dissipation hole. The electric ball valve 502 is installed on the ventilation channel 501. When the electric ball valve 502 is working, the ventilation channel 501 is closed. The ventilation port of the rotating platform 503 rotates around the center of the rotating platform 503 as the axis.

[0070] The ventilation hole 5 has an anti-rollover function, and the method for realizing the anti-rollover function includes:

[0071] When the unmanned boat detects that the heel angle is greater than a first preset value, the vents of the vents 5 close to the heel direction face the heel direction, and the turbofan inside this vent 5 works in a blowing state. The vents of the vents 5 away from the heel direction face the opposite direction of the heel direction, and the turbofan inside this vent 5 works in a suction state, applying a force opposite to the heel direction to the unmanned boat to stabilize it.

[0072] When the unmanned boat detects that the heel angle is greater than a second preset value, the two turbofans stop working, and the electric ball valve 502 works to close the ventilation channel 501 to prevent water from entering; the second preset value is greater than the first preset value.

[0073] The payload equipment bracket 9 is provided with a microwave antenna 8, a 4G / 5G antenna 11, a laser radar 12, a rear camera 14, an electromagnetic switch 16, rescue equipment 17, a multi-degree-of-freedom rotation positioning body 46 and an ejection cylinder 47. The electromagnetic switch 16 is installed above the rescue equipment 17 to fix the rescue equipment 17. When the electromagnetic switch 16 is turned on, the rescue equipment 17 is released. The rescue equipment 17 is also connected to the ejection cylinder 47, and the ejection cylinder 47 is fixed on the multi-degree-of-freedom rotation positioning body 46. The payload equipment bracket 9 can be equipped with corresponding equipment at any time according to the different functions that need to be realized.

[0074] When the unmanned boat is relatively close to the object to be rescued, the rear camera 14 rotates to scan the position where the object to be rescued sends a distress signal to obtain an image, extract the characteristic parameters of the image, and calculate the relative position, direction and heading of the unmanned boat and the object to be rescued.

[0075] The rescue steps include: first turning on the electromagnetic switch 16 to release the rescue equipment 17, then the multi-degree-of-freedom rotating positioning body 46 adjusts the angle of the ejection cylinder 47, and the ejection cylinder 47 adjusts the force to accurately eject the rescue equipment 17 to the person to be rescued.
