[0025] 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.

[0026] For aquatic robots, it is understood that they include boats, vessels, and other machines that can move on and / or underwater, as well as boats and vessels with grasping mechanisms.

[0027] Reference Figures 1 to 3This utility model provides a multifunctional police water robot, including a surface robot 100 and an underwater robot 200. The surface robot 100 is equipped with a battery pack, a wireless communication module 110, a surface computer 120, a surface patrol camera 131, and a first speaker 132. The surface patrol camera 131 and the first speaker 132 are electrically connected to the surface computer 120. The surface computer 120 is connected to a remote monitoring computer 310 and / or a mobile phone 320 via the wireless communication module 110. The underwater robot 200 is equipped with an underwater computer 210, an underwater patrol camera 221, and a second speaker 222. The underwater patrol camera 221 and the second speaker 222 are electrically connected to the underwater computer 210. A power cable 142 connects the underwater robot 200 to the battery pack. The underwater computer 210 is connected to the remote monitoring computer 310 and / or the mobile phone 320 via the power cable 142, the surface computer 120, and the wireless communication module 110.

[0028] Reference Figures 1 to 3 The surface robot 100 and the underwater robot 200 are combined into a water robot. The underwater robot 200, the surface robot 100, the network, and the remote monitoring computer 310 are networked together.

[0029] Commonly understood knowledge includes battery packs similar to those in modern electric vehicles. The battery pack of this invention comprises multiple batteries, grouped into one or more groups. Multiple batteries within each group are connected in series and / or parallel, enabling the battery pack to function as one or more power sources of a specific capacity and voltage, such as a DC 24V, 60kWh power source. The battery pack supplies power to various electrical components, including the wireless communication module 110, surface computer 120, surface patrol camera 131, underwater patrol camera 221, first speaker 132, second speaker 222, etc., which are electrically connected to the battery pack. To avoid... Figure 3 The wiring is overly crisscrossed and confusing, omitting electrical connections between the battery pack and various electrical components. Furthermore, the battery pack is connected to a level adapter circuit / module, which converts the battery / power supply to 12V, 5V, 3.3V, etc., to accommodate different pins of various chip components.

[0030] It is understood that this utility model utilizes electrical knowledge of power line communication; specifically, refer to... Figure 3 The surface robot 100 and / or underwater robot 200 are equipped with power line carrier communication modules. The power cable frequency and the communication signal frequency are selected differently. The communication signal (communication wave) can be demodulated to remove the power wave, such as through low-frequency filtering, high-frequency filtering, or frequency-selective filtering, allowing the computer to obtain the accurate demodulated signal for precise control of the corresponding electrical components. This technology is commonly found in current electricity meters, allowing for direct remote reading of meter information via power lines.

[0031] The lake's depth is mainly several meters, with some areas reaching depths of tens of meters. The cable between the surface robot 100 and the underwater robot 200 is set to a corresponding length based on the water depth the underwater robot needs to reach. For example, the cable between the surface robot 100 and the underwater robot 200 can be 30 meters long, allowing for the inspection of a 30-meter deep pit, the inspection of a shallow area with a radius of approximately 30 meters, and the transport of salvaged items or items awaiting diving over a 30-meter distance.

[0032] Reference Figure 3 Ideally, the underwater robot 200 is equipped with a water depth sensor 242 that is electrically connected to the second navigation control motherboard 230. For example, the underwater robot 200 is used to measure the distance between itself and the water surface using ultrasonic waves, and the water depth sensor 242 is used to locate the underwater robot 200's water depth position.

[0033] Reference Figure 1 , Figure 2 Preferably, the surface robot 100 and / or the underwater robot 200 are equipped with a cable retractor 141. After the surface robot 100 and / or the underwater robot 200 are separated, the surface robot 100 and the underwater robot 200 retain a pre-set length X0, for example, 2 meters. Based on the feedback value X1 from the depth sensor 242, the cable retractor 141 rotates a predetermined total angle, and a cable of the corresponding length X2 is pulled out between the surface robot 100 and the underwater robot 200, where X2 = X1 + pre-set length X0.

[0034] And / or, while retaining the pre-length quantity X0, the motor of the cable retractor 141 continues to rotate to retract the cable while the underwater robot 200 is submerging; while the underwater robot 200 is submerging, the motor of the cable retractor 141 continues to rotate to release the cable.

[0035] The cable retractor 141 is connected to an encoder for detecting the length of the cable being retracted via a motor drive.

[0036] In this invention, the surface robot 100 and the underwater robot 200 work together, with one responsible for surface security and the other for underwater security, salvage, and search and rescue assistance, making it a multi-functional police tool. It is understood that the underwater robot 200 is not limited to underwater operations; as described below, it can also be used to bring salvaged items to the surface or even transport them to the shore.

[0037] Reference Figure 3The surface computer 120 is divided into two parts: a tablet-based water robot computer 121 and a first embedded computer 122. The underwater computer 210 also uses an embedded computer, namely the second embedded computer. Thus, the first embedded computer 122 and the second embedded computer are electrically connected to the water robot computer 121 via a network switch. The first embedded computer 122 and the second embedded computer are actually connected to the remote monitoring computer 310 and / or mobile phone 320 via the water robot computer 121. The remote monitoring computer 310 is typically placed in a central control room, such as a police station.

[0038] The first embedded computer (122) and the second embedded computer can both be Raspberry Pi. Embedded computers are adapted to specific applications, are highly specialized, have low power consumption, high reliability, can withstand harsh environments, and are easy to miniaturize. Examples include STM32MP135 core boards, single-board computers, and industrial control computers, commonly used in industrial automation, medical equipment, and smart homes. Tablet PCs can also be considered a type of embedded computer.

[0039] A local area network is formed through a network switch, enabling the software Mission Planner and qgroundcontrol between computers to exchange data through the network. The water robot computer 121 collects data from each embedded computer, such as radar sensor 163 and sonar scanner 243. The water robot computer 121 then tells each navigation control motherboard PIXHAWK what to do next through the embedded computers.

[0040] Understandably, referring to Figure 3 The surface robot 100 includes a first flight control motherboard 150 and a first thruster 162. The first flight control motherboard 150 is electrically connected to the surface computer 120, and the first thruster 162 is electrically connected to the first flight control motherboard 150. The underwater robot 200 includes a second flight control motherboard 230 and a second thruster 244. The second flight control motherboard 230 is electrically connected to the underwater computer 210, and the second thruster 244 is electrically connected to the second flight control motherboard 230. (Refer to...) Figure 3Both the surface robot 100 and the underwater robot 200 use existing Pixhawk boards that can be directly referenced, such as the RadioLink brand, for controlling drones, unmanned surface vessels, and RC cars. These boards support multiple channels (such as 5CH, 8CH, 16CH) and high anti-interference technology (such as FHSS spread spectrum). The RC4GS V3 supports real-time telemetry (such as battery voltage monitoring) and gyroscope stabilization. The T16D multi-channel remote control drones and boats are equipped with a USB interface for connecting to an embedded computer, a POWER power interface, an ACC 3.3V level input interface, a GPS interface, an I2C interface for connecting to the depth sensor 242 (depth positioning sensor) and sonar scanner 243, a TELEM interface for connecting to the radar sensor 163, and output interfaces AUX OUT and MAIN OUT for connecting to the robotic arm servo motor, thruster motor, electromagnet, warning light 165, underwater lighting light 245, and latching device 170.

[0041] Reference Figure 1 , Figure 2 It is understandable that the thrusters of both the surface robot 100 and the underwater robot 200 can be divided into two groups, left and right. When the two groups of thrusters work with different thrust, the hull can be turned.

[0042] Reference Figure 1 , Figure 2 The surface inspection camera 131 is a panoramic camera (360-degree panoramic camera) installed on the top of the surface robot 100.

[0043] Reference Figures 1 to 3 In some embodiments of this utility model, the surface robot 100 is equipped with a first navigation control motherboard 150 electrically connected to the surface computer 120, and a first robotic arm 161 electrically connected to the first navigation control motherboard 150. The underwater robot 200 is equipped with a second navigation control motherboard 230 electrically connected to the underwater computer 210, and a second robotic arm 241 electrically connected to the second navigation control motherboard 230. Both the first robotic arm 161 and the second robotic arm 241 are used to grab objects, such as clothes and garbage floating on the lake surface, or criminal items waiting to be retrieved from the bottom of the water.

[0044] Reference Figures 1 to 3 In some embodiments of this utility model, the first robotic arm 161 is equipped with a first arm-following camera 133 electrically connected to the surface computer 120, and the second robotic arm 241 is equipped with a second arm-following camera 223 electrically connected to the underwater computer 210. The first robotic arm 161 and the second robotic arm 241 can accurately grasp objects based on real-time close-up images. The second robotic arm 241 can send the second arm-following camera 223 to narrow crevices or other underwater locations to facilitate the discovery of targets to be salvaged in complex underwater environments.

[0045] Reference Figure 2 , Figure 3 Ideally, the underwater robot 200 is equipped with an underwater lighting lamp 245 that is electrically connected to the second navigation control motherboard 230.

[0046] Reference Figure 1 , Figure 2 In some embodiments of this utility model, life rings 180 are provided on both sides of the water surface robot 100. The life rings 180 can be taken by the water swimmers themselves, or they can be released by the hook of the water surface robot 100. For example, the hook is connected to a corresponding electric cylinder / electromagnetic cylinder, and the hook extends and / or swings to release the life rings 180.

[0047] The 310 computer can be remotely monitored by installing remote control software, such as TeamViewer.

[0051] The IDs of the remote monitoring computer 310, the aquatic robot computer 121, the network switch, the first embedded computer 122, and the underwater computer 210 can be found in [reference needed]. Figure 3 The surface robot 100 and underwater robot 200 can be remotely controlled via the graphical control interface of the remote control software, as well as the broadcasting of the first speaker 132 and the second speaker 222, etc.

[0052] The Aquatic Robot PC 121 (tablet) needs to support and run smoothly various applications simultaneously, including Mission Planner, qgroundcontrol navigation control software, panoramic camera monitoring software, audio player, audio communication Microsoft Teams, SSH, etc.

[0053] The operation process of this utility model can be as follows: The remote monitoring computer 310 checks the shore-based camera and the water surface patrol camera 131. When it finds people playing in the water, or finds floating clothes, fishing boats, etc. on the water surface, or finds clothes and vehicles on the shore, the water surface robot 100 starts patrolling according to the control or autonomously. The underwater robot 200 follows at the normal water depth, such as 2 meters, as recorded below. The underwater robot 200 and the water surface robot 100 can also combine during patrol to save the power consumption of the water robot. After an abnormality is found, they can separate and work separately.

[0054] The panoramic camera of the surface robot 100 is used to search a wide area for water players, their items, and / or the waves they create, in order to quickly lock onto the target. Compared with the panoramic patrol of the surface, the underwater patrol camera 221 can patrol underwater to a certain extent. Preferably, the underwater robot 200 is equipped with multiple underwater patrol cameras 221 at intervals along the circumference, and the computer software is set with humanoid learning and locking programs.

[0055] After installing audio communication software such as Microsoft Teams on the aquatic robot computer 121 and the remote monitoring computer 310, refer to... Figure 3 The remote monitor can send audio signals to the first and second embedded computers via microphone and remote monitoring computer 310, and play voice commands through power amplifier and speakers. During the patrol of the water robot, the first speaker 132 can routinely play "Citizens, this is XXX District. Please abide by the relevant regulations and do not engage in illegal activities such as swimming, fishing, or washing in this district."

[0056] During the waterborne robot's patrol, the second speaker 222 can routinely broadcast "Diving is dangerous, please come ashore immediately and do not engage in any illegal activities in this area";

[0057] When the surface patrol camera 131 and / or the underwater patrol camera 221 detects a person playing in the water, the remote monitor will see the detection on the screen. The water robot will be remotely controlled or will automatically stop in the water area. The water robot will continue to broadcast relevant warnings until the person playing in the water safely comes ashore.

[0058] When the surface patrol camera 131 and / or the shore-based camera detects a person about to drown, the surface robot 100 approaches the person and announces, "I am a lifeboat and am approaching you. Please do not panic. Keep your face up and breathe. Once you are close, grab the handrail on the boat and put on the life ring 180."

[0059] On the other hand, when the underwater patrol camera 221 detects a drowning person or a target to be retrieved, the remote monitor will detect it on the screen and notify the lifeboat and rescue workers to come to the scene. The remote monitor will remotely control the underwater robot 200 and its robotic arm to retrieve the item, and the second speaker 222 will be used to guide the rescue workers.

[0060] Reference Figure 3 In some embodiments of this utility model, the surface robot 100 and / or the underwater robot 200 are equipped with a GPS receiver 164, which is connected to the corresponding navigation control motherboard. In this utility model, both the surface robot 100 and the underwater robot 200 can be satellite-navigated; alternatively, the surface robot 100 can follow satellite navigation while the underwater robot 200 accompanies it.

[0061] Reference Figure 1 , Figure 2 The hull of the surface robot 100 is the first hull, which is a closed cabin. The sides of the first hull's roof need to accommodate multiple lifebuoys 180. The first hull needs to house numerous components, such as battery packs, wireless communication modules 110, a water robot computer 121, a network switch, a first embedded computer 122, a first navigation control motherboard 150, radar sensors 163, and a GPS receiver 164. The radar sensors 163, GPS receiver 164, and the first speaker 132 are generally located in the bow window, the bow flank, or the stern flank.

[0062] Compared with existing technologies, the beneficial effects of this application include: simultaneous surface and underwater surveillance and patrol, facilitating emergency rescue and government search and rescue, without the entanglement and restrictions of shore-based connections, flexible changes in real-time patrol areas, and easy and rapid completion of security for the entire water area; remote monitoring and remote alarms, security can be completed without leaving the area, and satellite positioning-based patrols enable autonomous patrols around the clock.

[0063] Through AI inference such as DeepSeek, autonomous navigation via satellite positioning and automatic obstacle avoidance via radar and sonar detection can be achieved.

[0064] Reference Figure 3 In some embodiments of this utility model, the wireless communication module 110 is a 4G / 5G communication network module, and the entire water area is within the coverage of the digital network, allowing the water robot to reach every corner of the water area.

[0065] Reference Figure 3 The surface robot 100 is equipped with a radar sensor 163 electrically connected to the first navigation control motherboard 150, and the underwater robot 200 is equipped with a sonar scanner 243 electrically connected to the second navigation control motherboard 230. Both the radar sensor 163 and the sonar scanner 243 are used to detect the presence of obstacles, enabling the robots to avoid obstacles. It is understandable that ultrasonic sensors, etc., can also be used to detect obstacles, and are equivalent substitutes.

[0066] Reference Figure 2 , Figure 3 In some embodiments of this utility model, the water surface robot 100 is equipped with a warning light 165 electrically connected to the first flight control motherboard 150, which serves as a warning to water swimmers at dusk and night.

[0067] Reference Figure 1 , Figure 2 In some embodiments of this utility model, the hull of the underwater robot 200 is a second hull, and the second hull forms a storage recess 250. The storage recess 250 is used to store salvaged items, items to be submerged, and / or surface robots 100, such as search and rescue items salvaged from the seabed, or rescue items to be brought to the seabed, so that they can be easily accessed by the diving crew.

[0068] Reference Figure 2 The inner bottom of the second hull can be used to house the control cabin, which contains an underwater computer 210, a second navigation control motherboard 230, a power line carrier communication module, etc. Compared to the first hull, the control cabin only needs to hold fewer items, and the control cabin can be miniaturized.

[0069] Reference Figure 3 In some embodiments of this utility model, the surface robot 100 is equipped with an electromagnet electrically connected to the surface computer 120. The electromagnet is used to connect to the underwater robot 200 by attraction, that is, the underwater robot 200 is equipped with a metal part for being attracted by the electromagnet, and the surface robot 100 and the underwater robot 200 are magnetically attracted together. Specifically, the hull of the underwater robot 200 may be V-shaped. The underwater robot 200 rises and approaches and / or slides along the water surface to approach the surface robot 100. After the two are relatively close, or even after a certain degree of preliminary combination, they are fully combined under the action of the electromagnet, which plays a guiding and positioning role.

[0070] In some configurations, the surface robot 100 is equipped with a proximity switch that is electrically connected to the surface computer 120 or the first navigation control motherboard 150. The proximity switch is used to detect when the surface robot 100 and the underwater robot 200 are in position together.

[0071] Reference Figures 1 to 3 In some embodiments of this utility model, the surface robot 100 is equipped with a latching device 170 electrically connected to the surface computer 120, and the latching hook 171 of the latching device 170 is used to latch the underwater robot 200. Specifically, the latching device 170 includes a housing and a latching power component, such as a motor, an electric cylinder, or an electromagnetic cylinder. The latch 171 is rotatably connected to the housing, the motor can directly drive the latch 171 to rotate, and the electric cylinder drives the latch 171 to rotate through a linkage structure.

[0072] Reference Figure 1 , Figure 2 In some embodiments of this utility model, the underwater robot 200 is provided with a handle 260, which is used to be lifted by a person or by a crane.

[0073] Reference Figure 1 , Figure 2 The underwater robot 200 is equipped with a second thruster 244 for forward and backward movement and a second thruster 244 for lifting and lowering.

[0074] Reference Figure 1 , Figure 2In some embodiments of this utility model, the underwater robot 200 is equipped with one or more buoyancy modules 270. The buoyancy modules 270 are used for water intake or drainage, enabling the underwater robot 200 to submerge or surface, reducing the power consumption of the second thruster 244, and allowing for faster submersion and surfacing. Specifically, the buoyancy module 270 includes a hollow float, which is equipped with an on / off valve or water inlet pump suitable for water intake into its cavity, and a drainage pump communicating with the cavity.
