[0043] 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.

[0044] 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.

[0045] 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.

[0046] Reference Figure 1 As shown, there are two hulls 101, and the two hulls 101 are symmetrically arranged relative to the frame 102, and the two hulls 101 are parallel to each other, so that the structure is simple and easy to assemble.

[0047] Specifically, each hull 101 includes a buoyancy portion 12 and a power portion 14, and the power portion 14 is connected to the buoyancy portion 12. Figure 2 As shown, each hull 101 includes a buoyancy part 12 and two power parts 14, the two power parts 14 are respectively a first power part 141 and a second power part 142, the buoyancy part 12 has a first end and a second end opposite to each other along the length direction (e.g., front and rear direction) of the hull 101, wherein the first power part 141 is connected to the first end (e.g., front end) of the buoyancy part 12, and the second power part 142 is connected to the second end (e.g., rear end) of the buoyancy part 12. In other words, the buoyancy part 12 is connected between the two power parts 14, thereby enabling the hull 101 to have greater power. It should be noted that the power part 14 has a drainage function, and can drive the buoyancy part 12 to move by drainage; further, by adjusting the drainage direction of the power part 14, the power parts 12 at both ends of the buoyancy part 12 can give the buoyancy part 12 driving forces in different directions, and can drive the buoyancy part 12 to move forward, backward, turn left, turn right, etc.

[0048] 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.

[0049] Optionally, the power part 14 and the buoyancy part 12 are connected in a detachable manner, thereby facilitating the disassembly and assembly of the power part 14 and the buoyancy part 12. For example, the power part 14 and the buoyancy part 12 can be connected by fasteners such as screws. One of the power part 14 and the buoyancy part 12 is provided with a through hole, and the other is provided with a threaded hole. The screw passes through the through hole and is threadedly connected to the threaded hole. This connection method has a simple structure and is easy to implement.

[0050] like Figure 3 , Figure 4 As shown, the power unit 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 ship 100 when sailing. The two ends of the buoyancy unit 12 are respectively connected to the first end surfaces 111 of the two power units 14.

[0051] 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.

[0052] 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.

[0053] like Figure 4 and Figure 5 As shown, the power unit 14 includes a hull portion 11 and a power device 20, the power device 20 is connected to the hull portion 11, and at least two diversion channels are provided on the hull portion 11, each of which is opposite to the power device 20, so that the drainage of the power device 20 can flow out through the diversion channels, thereby facilitating the driving of the hull 101 to move. The set diversion channels, on the one hand, enable the drainage of the power device 20 to be discharged in time, and on the other hand, can also guide the water flow direction of the drainage of the power device 20, which is beneficial to adjust the navigation direction of the unmanned boat 100, and further beneficial to improve the driving effect of the power device 20 on the unmanned boat 100.

[0054] According to the hull 101 of the unmanned boat 100 of the embodiment of the present invention, a diversion channel is provided on the hull portion 11 of the power portion 14, and the diversion channel is opposite to the power device 20, so that the drainage of the power device 20 can flow out through the diversion channel, and then it is convenient to drive the hull 101 to move. The provided diversion channel, on the one hand, enables the drainage of the power device 20 to be discharged in time, and on the other hand, it can also guide the water flow direction of the drainage of the power device 20, which is beneficial to adjust the navigation direction of the unmanned boat 100, and further beneficial to improve the driving effect of the power device 20 on the unmanned boat 100.

[0055] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, the hull portion 11 has an installation cavity 110, and one side of the installation cavity 110 has an opening 1121. The power device 20 is arranged in the installation cavity 110, and the diversion channel is connected with the installation cavity 110. Therefore, the structure is simple and easy to implement. Moreover, after the installation cavity 110 is set, the hull portion 11 can also play a certain protective role for the power device 20, avoiding the power device 20 from being exposed to the outside and easily colliding with stones on the bottom of the water.

[0056] Furthermore, if Figure 3 , Figure 4 As shown, a protective grille 13 is provided on the opening 1121 of the installation cavity 110 , and the protective grille 13 can prevent debris such as water plants from entering the installation cavity 110 and affecting the navigation of the unmanned boat 100 .

[0057] In some embodiments of the present invention, Figure 4 and Figure 5 As shown, the power device 20 includes multiple groups of power components, thereby improving the driving force that the power device 20 can provide. There are multiple guide channels, and the multiple guide channels are spaced apart and correspond one-to-one to the multiple groups of power components, thereby avoiding the water flows in different guide channels from affecting each other.

[0058] Furthermore, if Figure 3 As shown, there may be two flow guiding channels, namely a first flow guiding channel 113 and a second flow guiding channel 114. 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.

[0059] like Figure 3 and Fig. 9 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 radial 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.

[0060] In some embodiments of the present invention, the central axis of the second outlet 1142 intersects with the central axis of the first outlet 1132 and the angle between the two is α. Specifically, the central axis of the second outlet 1142 and the central axis of the first outlet 1132 are in the same plane and intersect with each other, thereby defining the angle α, wherein the value range of α is 30-90 degrees. This allows a larger angle to be created between the propulsion force given to the hull 101 when the water flows out of the first outlet 1132 and the propulsion force given to the hull 101 when the water flows out of the second outlet 1142, thereby making it easier to turn the hull 101.

[0061] Optionally, α can be 30 degrees, 32 degrees, 35 degrees, 38 degrees, 40 degrees, 42 degrees, 45 degrees, 48 ​​degrees, 50 degrees, 52 degrees, 55 degrees, 58 degrees, 60 degrees, 62 degrees, 65 degrees, 66 degrees, 68 degrees, 70 degrees, 72 degrees, 74 degrees, 75 degrees, 76 degrees, 78 degrees, 80 degrees, 82 degrees, 84 degrees, 85 degrees, 86 degrees, 88 degrees or 90 degrees.

[0062] In some embodiments of the present invention, the hull 11 has an installation cavity 110, the first power assembly 201 and the second power assembly 202 are arranged in the installation cavity 110, and the first inlet 1131 and the second inlet 1141 are arranged on the same side wall of the installation cavity 110, thereby simplifying the structure. Figure 3 and Fig. 9 The first inlet 1131 of the first guide channel 113 and the second inlet 1141 of the second guide channel 114 are respectively located on the same side wall of the installation cavity 110, the first outlet 1132 of the first guide channel 113 is located on the second end surface of the hull portion 11, and the second outlet 1142 of the second guide channel 114 is located on the side away from the unmanned boat 100.

[0063] In some embodiments of the present invention, Fig. 9 As shown, the first outlet 1132 of the first power unit 141 and the first outlet 1132 of the second power unit 142 are respectively located on both sides of the length direction (e.g., the front-to-back direction) of the hull 11, and the second outlet 1142 of the first power unit 141 and the second outlet 1142 of the second power unit 142 are respectively located on both sides of the width direction (e.g., the left-to-right direction) of the hull 11, thereby facilitating the turning of the hull 11.

[0064] Specifically, refer to Fig. 9The first power unit 141 is located at the front side of the buoyancy unit 12, and the second power unit 142 is located at the rear side of the buoyancy unit 12. The first outlet 1132 of the first power unit 141 is open toward the front side, and the first outlet 1132 of the second power unit 142 is open toward the rear side. The second outlet 1142 of the first power unit 141 is open toward the right side, and the second outlet 1142 of the second power unit 142 is open toward the left side. Therefore, during the navigation of the unmanned boat 100, the adjustment of the hull 101 in the front, back, left and right directions can be achieved by controlling the working state of the corresponding power components.

[0065] Furthermore, if Fig. 9 As shown, the first power part 141 and the second power part 142 are centrally symmetrically distributed relative to the buoyancy part 12, so that the structure is simple and easy to install.

[0066] According to some embodiments of the present invention, Figure 5-Figure 7 As shown, the power device 20 may include: a mounting housing 21, a drive motor, a propeller housing 24 and a propeller 23. The mounting housing 21 is connected to the hull 11, and the drive motor is disposed in the mounting housing 21. In order to protect the drive motor, the drive motor may be sealed in the mounting housing 21, that is, the mounting housing 21 has a sealed cavity, and the drive motor is located in the cavity.

[0067] The paddle housing 24 is connected to the mounting housing 21, and has a water inlet 242 and a water outlet 241, the water outlet 241 is opposite to the diversion channel, the propeller 23 is arranged in the paddle housing 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.

[0068] 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 .

[0069] 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.

[0070] 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.

[0071] Among them, Figure 8 As 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.

[0072] 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 the drive motor 22 to short-circuit, but 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.

[0073] 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.

[0074] 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.

[0075] 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 .

[0076] According to some embodiments of the present invention, Figure 3-Figure 5As 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. This facilitates the installation of the protective tube 32.

[0077] 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.

[0078] 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.

[0079] 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.

[0080] According to some embodiments of the present invention, Figure 3As 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.

[0081] 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.

[0082] 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 .
