[0041] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0042] Reference below Figure 1-Figure 8 The unmanned boat according to the embodiment of the present invention is described. The unmanned boat 100 can be applied to surveying and mapping of oceans, lakes and rivers, hydrology and water quality monitoring, etc. Of course, the unmanned boat 100 can also be applied to other fields, which is not limited in this embodiment.

[0043] Reference Figure 1 The unmanned ship 100 includes a plurality of hulls 101, which are arranged in parallel and connected by a gantry 102. The plurality of hulls 101 can be used to carry the gantry 102, which can be used to carry cargo, batteries, etc. In the description of the present invention, "plurality" means two or more.

[0044] Reference Figure 1 As shown, two hulls 101 are arranged in parallel. Figure 2 As shown, each hull 101 includes a buoyancy portion 12 and two power portions 14. One of the power portions 14 is connected to one end (e.g., the front end) of the buoyancy portion 12, and the other power portion 14 is connected to the other end (e.g., the rear end) of the buoyancy portion 12. In other words, the buoyancy portion 12 is connected between the two power portions 14. It should be noted that the power portion 14 has a drainage function, and can drive the buoyancy portion 12 to move by drainage; further, by adjusting the drainage direction of the power portion 14, the power portions 12 located at both ends of the buoyancy portion 12 can give the buoyancy portion 12 driving forces in different directions, and can drive the buoyancy portion 12 to move forward, backward, turn left, turn right, etc.

[0045] For example, taking a hull 101 as an example, the process of adjusting the movement direction of the unmanned boat 100 is described as follows: when the unmanned boat 100 moves forward or backward, a power unit 14 can be controlled to start, and the hull 101 can be driven forward or backward. This operation can improve the movement flexibility of the unmanned boat 100, especially when the unmanned boat 100 is stranded, the unmanned boat 100 can be controlled to retreat according to the state of the unmanned boat 100, so that the unmanned boat 100 can automatically get out of the stranded state.

[0046] like Figure 3 , Figure 4 As shown, the power part 14 includes a first end surface 111, a second end surface, two side surfaces, a top surface and a bottom surface 112, the second end surface, the two side surfaces and the top surface are respectively formed as arc surfaces and the second end surface, the two side surfaces and the top surface are arc transitioned to reduce the resistance of the unmanned boat 100 during navigation. The two ends of the buoyancy part 12 are respectively connected to the first end surfaces 111 of the two hull parts 11.

[0047] In addition, the present invention does not limit the specific material or shape of the buoyancy part 12, as long as the buoyancy part 12 can float on the water surface. For example, the buoyancy part 12 can be an air bag; or the buoyancy part 12 can be made of a soft foaming material that does not absorb water, such as a foam piece; or the buoyancy part 12 can also be a hollow hard plastic, so that the buoyancy part 12 can float on the water surface while having a certain structural strength.

[0048] According to the unmanned boat 100 of the embodiment of the present invention, by arranging the power unit 14 at both ends of the buoyancy unit 12 and then adjusting the drainage direction of the power unit 14, the direction of the driving force applied to the buoyancy unit 12 by the power unit 14 can be adjusted, and then the buoyancy unit 12 can be driven forward, backward, turn left, turn right, etc., thereby improving the flexibility of the movement of the unmanned boat 100.

[0049] like Figure 3-Figure 5 As shown, according to some embodiments of the present invention, the power unit 14 may include: a hull 11, a power device 20 and a protective grille 13. The hull 11 is formed with an installation cavity 110 and a guide channel connected to the installation cavity 110. One side of the installation cavity 110 has an opening 1121, and the opening 1121 may be located on the bottom surface 112. Figure 5 As shown, the installation cavity 110 is suitable for installing the power device 20. Figure 3 , Figure 4 As shown, a protective grid 13 is provided on the opening 1121 of the installation cavity 110, and the protective grid 13 can prevent debris such as water plants from entering the installation cavity 110 and affecting the navigation of the unmanned boat 100. The power device 20 is opposite to the diversion channel, so that the drainage of the power device 20 can flow out through the diversion channel, thereby facilitating the driving of the hull 101 to move.

[0050] According to some embodiments of the present invention, Figure 5 , Figure 6 and Figure 7 As shown, the power device 20 of the unmanned ship 100 includes a mounting housing 21 and at least one set of power components, and the power components include a driving motor, a propeller housing 24 and a propeller 23.

[0051] In some embodiments, the mounting shell 21 is connected to the hull 11, and the drive motor is disposed in the mounting shell 21. In order to protect the drive motor, the drive motor can be sealed in the mounting shell 21, that is, the mounting shell 21 has a sealed cavity, and the drive motor is located in the cavity.

[0052] The paddle shell 24 is connected to the mounting shell 21, and the paddle shell 24 has a water inlet 242 and a water outlet 241, and the water outlet 241 is opposite to the diversion channel. The propeller 23 is arranged in the paddle shell 24, and the driving motor is connected to the propeller 23 to drive the propeller 23 to rotate. In this way, the propeller 23 can be used to drain water, and the discharged water can be discharged through the water outlet 241, thereby providing power for the movement of the hull 101. In addition, the paddle shell 24 provided can, on the one hand, play a certain protective role for the propeller 23. For example, when the unmanned boat 100 is stranded, the propeller 23 can be prevented from directly contacting the bottom of the water and being deformed and damaged. On the other hand, when the propeller 23 is draining water, it can also play a certain guiding role for the discharged water, so that the driving force applied by the propeller 23 to the unmanned boat 100 can be adjusted, which is conducive to enabling the propeller 23 to better drive the unmanned boat 100 to sail.

[0053] According to the power device 20 of the unmanned boat 100 of the embodiment of the present invention, the propeller 23 is arranged in the paddle shell 24, and the paddle shell 24 is connected to the mounting shell 21, and the paddle shell 24 has a water inlet 242 and a water outlet 241. Therefore, the paddle shell 24 can play a certain protective role on the propeller 23 on the one hand, so that the propeller 23 is not easily deformed and damaged. On the other hand, when the propeller 23 discharges water, it can also play a certain guiding role on the discharged water, so that the driving force applied to the unmanned boat by the propeller 23 can be adjusted, which is conducive to the propeller 23 being able to better drive the unmanned boat to sail.

[0054] In order to improve the driving force that the power device can provide, in some embodiments, such as Figure 6 As shown, the power components are divided into multiple groups, and the multiple groups of power components are arranged at intervals.

[0055] Furthermore, if Figure 3As shown, there may be two guide channels, namely the first guide channel 113 and the second guide channel 114. The inlets of the first guide channel 113 and the second guide channel 114 are respectively located on the same side wall of the installation cavity 110, and the outlets of the first guide channel 113 and the second guide channel 114 are respectively located on the second end surface of the hull portion 11 and the side away from the unmanned boat 100.

[0056] like Figure 4 , Figure 5 As shown, the power device 20 may include a first power assembly 201 and a second power assembly 202, wherein the first power assembly 201 is opposite to the first flow guiding channel 113, and the second power assembly 202 is opposite to the second flow guiding channel 114. On the one hand, the first power assembly 201 and the second power assembly 202 may be used to provide sufficient power for the hull 101, and on the other hand, the driving force between the first power assembly 201 and the second power assembly 202 may be used to realize the steering of the hull 101.

[0057] like Figure 3 As shown, in order to improve the flexibility of the hull 101 in turning, in some embodiments, the first guide channel 113 includes a first inlet 1131 and a first outlet 1132, the first inlet 1131 is opposite to the first power assembly 201, and the first outlet 1132 is located on the axis of the first guide channel 113, so that the water discharged from the first guide channel 113 can be used to drive the hull 101 to move forward or backward in the direction of the hull 101. The second guide channel 114 includes a second inlet 1141 and a second outlet 1142, the second inlet 1141 is opposite to the second power assembly 202, and the second outlet 1142 is open toward the warp outside of the second guide channel 114, that is, the water flow can be discharged from the second outlet 1142 located in the lateral direction, thereby providing a lateral driving force to the hull 101, thereby facilitating the turning of the hull 101.

[0058] For example, in some embodiments, reference Figure 2 , Figure 5Each hull 101 may have four power devices 20, which are respectively arranged on the installation cavity 110 in the hull part 11. Each power device 20 includes an installation shell 21, a drive motor, a propeller 23 and a paddle shell 24, wherein a cavity with an opening is formed in the installation shell 21, and the cavity is suitable for installing the drive motor. A through hole and two through holes are formed on the installation shell 21. Each power device 20 includes two drive motors, and the output shafts 221 of the two drive motors are respectively penetrated along the two through holes. There are two propellers 23, and each propeller 23 is respectively fixed to one end of the output shaft 221 away from the installation shell 21. The paddle shell 24 is roughly formed as a cylindrical shell structure, and each power device 20 includes two paddle shells 24, and a water outlet 241 is formed at one end of each paddle shell 24, and a water inlet 242 is formed on the side wall of the other end of the paddle shell 24, which opens toward the opening 111 of the installation cavity 110, and the water inlet 242 is connected to the water outlet 241. The paddle housing 24 is coaxially sleeved with the output shaft 221 on the outer periphery of the propeller 23, and one end of the paddle housing 24 away from the water outlet 241 is fixed to the mounting housing 21. One end of the water outlet 241 of the paddle housing 24 cooperates with the inlet of the first guide channel 113 and the second guide channel 114, so that the water outlet 241 of the paddle housing 24 is connected with the first guide channel 113 and the second guide channel 114.

[0059] In order to improve the drainage smoothness of the power device 20, in some embodiments, such as Figure 7 As shown, the water inlet 242 is disposed on the peripheral wall of the paddle housing 24 , and there are multiple water inlets 242 , which are spaced apart along the circumferential direction of the paddle housing 24 .

[0060] Alternatively, if Figure 7 As shown, the water outlet 241 is disposed at one end of the paddle housing 24 away from the mounting housing 21 (eg, the rear end of the paddle housing 24 ), thereby making the structure simple and easy to implement.

[0061] In some embodiments of the present invention, Figure 6 and Figure 7As shown, the portion of the paddle housing 24 away from the mounting housing 21 is formed as a tapered portion 243. Along the axial direction of the paddle housing 24 and in the direction from the mounting housing 21 to the paddle housing 24 (e.g., from the front to the back), the inner diameter of the tapered portion 243 gradually decreases. The water inlet 242 is located on the upstream side of the tapered portion 243, and the water outlet 241 is located at the downstream end of the tapered portion 243. The "upstream" and "downstream" mentioned here are based on the direction in which the water flows driven by the propeller 23. The water flows first as the upstream, and the water flows later as the downstream. Therefore, under the action of the propeller 23, the water will first enter the paddle housing 24 through the water inlet 242, then flow through the tapered portion 243, and finally be discharged from the water outlet 241. Since the inner diameter of the tapered portion 243 gradually decreases, the flow rate of the water will gradually increase, which is conducive to improving the driving effect of the propeller 23 on the unmanned boat 100.

[0062] Optionally, the paddle shell 24 is detachably connected to the mounting shell 21, thereby facilitating the disassembly and assembly of the paddle shell 24 and the mounting shell 21. In a specific application, the paddle shell 24 is detachably connected to the mounting shell 21 by a fastener, wherein the fastener may be, for example, a screw, wherein a through hole is provided on the paddle shell 24, and a threaded hole is provided on the mounting shell 21, and the screw may pass through the through hole and be threadedly connected with the threaded hole, and this connection method has a simple structure and is easy to implement.

[0063] In order to avoid interference between the drive motor and the paddle housing 24, in some embodiments, as shown in FIG. Figure 7 As shown, an escape opening 244 is provided at one end of the propeller housing 24 close to the mounting housing 21 (eg, the front end of the propeller housing 24 ), and the output shaft 221 of the driving motor passes through the escape opening 244 and extends into the propeller housing 24 to be connected to the propeller 23 .

[0064] In some embodiments of the present invention, Figure 6 As shown, a connecting column 25 is provided on the outer surface of the mounting shell 21. The connecting column 25 has a connecting hole 250. The connecting hole 250 is connected to the inside of the mounting shell 21 for the connecting wire 31 of the driving motor to pass through, thereby facilitating the routing of the connecting wire 31.

[0065] According to some embodiments of the present invention, Figure 3 , Figure 4 As shown, the hull portion 11 has a wire hole 115, which passes through the hull portion 11 and is connected to the installation cavity 110. Further, the unmanned boat 100 may also include: an electric control module, a protective tube 32 and a connecting wire 31. The connecting wire 31 may be a signal wire and / or a power wire, and the electric control module may include a controller and a battery.

[0066] Among them, Figure 8As shown, the protective tube 32 is passed through the wire hole 115, one end of the protective tube 32 is sealed and connected to the power device 20, and the other end of the protective tube 32 is sealed and connected to the electronic control module. The connecting wire 31 is passed through the protective tube 32, and the power device 20 is electrically connected to the electronic control module through the connecting wire 31. Furthermore, one end of the connecting wire 31 can be electrically connected to the drive motor along the connecting hole 250, and the other end of the connecting wire 31 is electrically connected to the controller or the battery. Therefore, by providing the protective tube 32, not only can water be prevented from entering the cavity along the wire hole 115 and near the drive motor, causing a short circuit in the drive motor, but also the gas in the drive motor can be discharged to the outside world along the wire hole 115 and the protective tube 32 in turn, thereby solving the sealing problem caused by the increase in air pressure in the cavity due to the heat generated by the drive motor.

[0067] Furthermore, the power device 20 has a connecting column 25, one end of the protective tube 32 is sleeved on the connecting column 25, the protective tube 32 is sealed and connected to the connecting column 25, the connecting column 25 has a connecting hole 250, and the connecting wire 31 is passed through the connecting hole 250. The connecting hole 250 is connected to the cavity of the mounting shell 21. In this way, not only can water be prevented from entering the cavity along the connecting hole 250 to cause a short circuit in the driving motor, but also the gas in the cavity can be discharged to the outside through the connecting hole 250 and the protective tube 32 in turn. In order to improve the connection sealing between the protective tube 32 and the connecting column 25, in some embodiments, the outer peripheral wall of the connecting column 25 has a pagoda pattern.

[0068] In order to facilitate fixing of the protection tube 32, in some embodiments, as Figure 3 , Figure 4 As shown, the end of the hull portion 11 has a wire groove 1112, the wire hole 115 is located in the wire groove 1112, and part of the protective tube 32 is embedded in the wire groove 1112. Therefore, the wire hole 115 and the wire groove 1112 can be used to guide the connection line between the power device 20 and the electronic control module. Further, there can be multiple wire grooves 1112, each wire groove 1112 extends in the radial direction of the hull portion 11, and the multiple wire grooves 1112 are spaced apart along the circumferential direction of the hull portion 11. Therefore, the lead-out direction of the protective tube 32 can be selected according to the situation, which is convenient for installation.

[0069] In some embodiments, Figure 6 As shown, the power device 20 may include a mounting housing 21, a drive motor, a propeller shell 24 and a propeller 23. The mounting housing 21 is sealed and connected to a protective tube 32. Thus, water can be prevented from entering the mounting housing 21. In order to protect the drive motor, the drive motor is arranged in the mounting housing 21, that is, the mounting housing 21 has a sealed cavity, and the drive motor is located in the cavity. The drive motor is communicatively connected to the connecting wire 31, so that the connecting wire 31 can be used to power the drive motor.

[0070] The output shaft 221 of the driving motor can pass through the mounting housing 21 to be connected to the propeller 23, thereby driving the propeller 23 to rotate. Figure 6 As shown, the paddle shell 24 is connected to the mounting shell 21 , and has a water inlet 242 and a water outlet 241 , the water outlet 241 is opposite to the guide channel, and the propeller 23 is arranged in the paddle shell 24 , so that the paddle shell 24 can be used to protect the propeller 23 .

[0071] According to some embodiments of the present invention, Figure 3-Figure 5 As shown, the power unit 14 may include a hull 11. The hull 11 has an installation cavity 110, and the power device 20 is disposed in the installation cavity 110. The hull 11 has a wire hole 115, which passes through the hull 11 and is connected to the installation cavity 110, and the protective tube 32 is disposed in the wire hole 115.

[0072] This facilitates installation of the protection tube 32 .

[0073] According to some embodiments of the present invention, Figure 3 As shown, the unmanned boat 100 may further include a protection rod 116 for protecting the bottom of the power unit 14, one end of the protection rod 116 is connected to the power unit 14, and the other end of the protection rod 116 is connected to the power unit 14 through a fixing assembly, so that the protection rod 116 is fixed to the power unit 14. Further, one end of the protection rod 116 is plugged into the power unit 14.

[0074] In some embodiments, Figure 3 As shown, the fixing assembly includes a fixing seat 1163, the other end of the protective rod 116 is inserted into the fixing seat 1163, and the fixing seat 1163 is fixed to the power unit 14 by screws. This facilitates the fixing of the protective rod 116 to the power unit 14. It should be noted that when installing the protective rod 116, one end of the protective rod 116 can be inserted into the power unit 114 first, and then the other end of the protective rod 32 can be inserted into the fixing seat 1163, and finally the fixing seat 1163 is installed on the power unit 14 by screws, so that the protective rod 116 can be installed to the power unit 14.

[0075] It should be noted that the fixing method of the protective rod 116 is not limited to this. For example, in some embodiments, the fixing assembly includes: a threaded member and a fixing cover, the fixing cover is provided on the protective rod 116, and the fixing cover is fixed to the power unit 14 through a threaded member. When installing the protective rod 116, one end of the protective rod 116 can be inserted into the power unit 114 first, and then the other end of the protective rod 32 is attached to the power unit 14 by using the fixing cover, and then the fixing cover is fixed to the power unit 14 by using the threaded member, so that the protective rod 116 can be installed to the power unit 14. Furthermore, there can be multiple threaded members, and some of the threaded members are located on one side of the protective rod 116, and some of the threaded members are located on the other side of the protective rod 116. In this way, the installation stability and reliability of the protective rod 116 can be improved.

[0076] According to some embodiments of the present invention, Figure 3 As shown, the protective rod 116 may include a first section 1161 and a second section 1162. One end of the first section 1161 is connected to the power unit 14 through a fixing assembly, the other end of the second section 1162 is connected to the first section 1161, and the other end of the second section 1162 is plugged into the power unit 14. The angle between the first section 1161 and the second section 1162 is an obtuse angle. Thus, the first section 1161 and the second section 1162 can form an enclosing structure to wrap up the power unit 14, thereby better protecting the power unit 14.

[0077] Furthermore, if Figure 5 As shown, the end of the first section 1161 away from the second section 1162 is connected to the bottom surface 112 of the hull 11 through the fixing seat 1163, and the end of the second section 1162 away from the first section 1161 is connected to the second end surface. Specifically, a mounting hole may be formed on the second end surface, and the end of the second section 1162 away from the first section 1161 cooperates with the mounting hole. During installation, the end of the second section 1162 away from the first section 1161 is first matched with the mounting hole, and then the end of the first section 1161 away from the second section 1162 is connected to the bottom surface 112 of the hull 11 through the fixing seat 1163. In this way, the installation strength of the protective rod 116 is guaranteed, and the assembly difficulty of the unmanned ship 100 is reduced. In this embodiment, the provision of the protective rod 116 ensures the navigation safety of the unmanned ship 100 and prevents the unmanned ship 100 from damaging the hull 11 of the unmanned ship when it is stranded.

[0078] In order to avoid stress concentration between the first section 1161 and the second section 1162, in some embodiments, the first section 1161 and the second section 1162 are smoothly transitioned. This can improve the structural strength of the protection rod 116. Figure 1 , Figure 2 As shown, in some embodiments, there are multiple protection rods 116, and the multiple protection rods 116 are arranged in parallel. Thus, the power unit 14 can be better protected. Figure 3 , Figure 4 As shown, each power unit 14 is provided with at least two protection rods 116 .
