Description

Technical Field

[0001] The invention belongs to the technical field of propellers, and in particular relates to a propeller device for an unmanned ship. Background Art

[0002] An unmanned boat is a highly integrated surface-based robot that is usually controlled by remote control or AI navigation programs. With the help of positioning and sensor systems, it can perform tasks on the water surface according to preset routes. It is widely used in aquatic environment monitoring, personnel search and rescue, water quality testing, fishery resource surveys and other fields. With the rapid development of unmanned technology, small unmanned boats have gradually become an important tool for surface operations. Their small size, shallow draft and maneuverability enable them to replace manual labor to complete operations in complex waters, especially in narrow waters or dangerous environments. They show significant advantages.

[0003] The propeller of an unmanned ship is the core of its power system, which directly affects the navigation performance and mission execution capability. The working principle of the propeller of an unmanned ship is based on the reaction force principle, that is, by spraying matter in one direction, a thrust in the opposite direction is generated to push the ship forward. The motor drives the rim to rotate, and the blades rotate with the rim, thereby pushing the water flow to generate thrust. When an unmanned ship is operating on the water, it needs to face various impurities in the water, such as water plants, fishing lines and various silk threads. For water plants, the rotating blades can directly crush them without affecting the rotating blades, while the silk threads and fishing lines will be sucked into the rotating blades with the water flow, and the rotating blades cannot stir the silk threads and fishing lines. The silk threads and fishing lines will be entangled on the rotating blade shaft, which in turn affects the rotation speed of the rotating blade, resulting in a decrease in the power of the entire propeller, affecting the normal operation of the unmanned boat. In order to reduce the impact of underwater fishing lines and various silk threads on the propeller, the existing method is to set a filter at the water inlet to isolate the fishing lines and silk threads. However, in order to allow water to enter the propeller, the opening of the filter should not be too small. The filter in a static state has a weak ability to intercept silk threads and fishing lines. The fishing lines and silk threads are likely to enter the propeller along the surface of the filter, causing the fishing lines to be entangled on the blade shaft, affecting the rotation speed of the blade shaft, and thus affecting the movement of the unmanned boat.

[0045] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] See also Figure 1-13 As shown, the present invention is a propulsion device for an unmanned ship, comprising: a propulsion housing 1, a driving motor 6 arranged in the cavity of the propulsion housing 1, a gear box 5 connected to the output end of the driving motor 6, and a rotating blade 4 connected to the other end of the gear box 5; a connecting housing 2 is fixedly arranged at the front end of the entire propulsion housing 1, and is connected to the protective cover 3 through the connecting housing 2 through a plurality of screws, and an arc-shaped water inlet 7 is opened on the side of the propulsion housing 1, so that the opening of the water inlet 7 is perpendicular to the channel of the protective cover 3, and the water inlet 7 has a larger opening space, and the rotating blade 4 is rotated under the drive of the driving motor 6, so that water flows into along the water inlet 7 and is discharged from the end of the protective cover 3, thereby pulling the entire unmanned ship upward.

[0048] like Figure 1 As shown, the two sets of thrusters are connected to the bottom mounting frame of the unmanned boat using a set of assembly top plates 10, so that the two sets of thrusters are respectively located on both sides of the bottom of the boat. The bottoms of the two sets of assembly top plates 10 are reinforced and connected to the two sets of thrusters through supporting main plates 9 and supporting cross plates 8, so as to facilitate the disassembly and assembly of the entire unmanned boat and the thrusters.

[0049] In order to reduce the entanglement of the propeller with debris when the unmanned boat walks on the water surface, multiple groups of anti-entanglement sleeves 14 are arranged at the cavity of the water inlet 7, and the multiple groups of anti-entanglement sleeves 14 are distributed in an arc shape with equal intervals to cover the entire water inlet 7, so that the gap between two adjacent groups of anti-entanglement sleeves 14 can be used for the movement of water flow. At the same time, the anti-entanglement sleeves 14 can intercept fishing lines in the water. However, due to the strong attraction of the water flow, the anti-entanglement sleeves 14 placed separately may cause the fishing line to enter the rotating blade 4 along the gap between the two groups of anti-entanglement sleeves 14 due to the existence of the gap. Therefore, the design sets the support connecting rod 13 in the anti-entanglement sleeve 14, such as Figure 1 as well as Figure 5 As shown, a spiral thread groove 18 is provided on the surface of each group of guide inner rods 15, and a hemispherical support main board 9 is fixedly provided on the inner wall of the anti-entanglement sleeve 14, and the moving block 19 is embedded in the hole of the thread groove 18, and the entire anti-entanglement sleeve 14 can move radially outside the guide inner rod 15, so that the anti-entanglement sleeve 14 will move in a rotational manner along the outside of the guide inner rod 15 and along the trajectory of the thread groove 18. Through the rotation of the anti-entanglement sleeve 14, compared with the anti-entanglement sleeve 14 placed alone, the effect on impurities such as fishing lines is better.

[0050] In order to complete the above operations, the design Figure 7As shown, a reinforcing connecting plate 23 is sleeved on the outer wall of the anti-entanglement sleeve 14 on the side away from the supporting connecting rod 13, and a plurality of assembly matching holes 22 are opened on the surface of the reinforcing connecting plate 23, and each assembly matching hole 22 is rotatably sleeved on the outside of the anti-entanglement sleeve 14, that is, by driving the reinforcing connecting plate 23, the assembly matching hole 22 can drag the anti-entanglement sleeve 14 to move, and then the anti-entanglement sleeve 14 can be moved along the supporting connecting rod 13 in a rotating state, so that any existing fishing line is wrapped around the periphery of each anti-entanglement sleeve 14 to prevent the fishing line from passing through the anti-entanglement sleeve 14 and entering the rotating blade 4.

[0051] In order to further complete the above functions, Figure 1 As shown, an electric screw 11 is arranged on the lower end surface of the assembly top plate 10, so that the screw connected to the electric screw 11 rotates, and the screw sleeve arranged outside the screw moves forward and backward along the bottom of the assembly top plate 10, and the plug-in connecting rod 12 is inserted into the bottom of the screw sleeve, so that the support connecting rod 13 is fixed at the bottom of the plug-in connecting rod 12, and the front end of the support connecting rod 13 can be fixed to the surface of the reinforcement connecting plate 23, and the support connecting rod 13 and the plug-in connecting rod 12 are distributed in a T shape, so that the support connecting rod 13 is respectively connected to the reinforcement connecting plates 23 of the left and right groups of thrusters, thereby realizing the synchronous driving of the anti-entanglement sleeve 14 to move along the outside of the support connecting rod 13.

[0052] In order to further maintain the stability of the anti-entanglement sleeve 14 and the supporting connecting rod 13, a group of limiting arc plate portions 48 are fixedly provided on the outer wall of the connecting shell 2, so that a plurality of groups of openings are opened on the surface of the limiting arc plate portion 48 to allow the anti-entanglement sleeve 14 to slide through, and the position of the openings corresponds one to one with the position and number of the anti-entanglement sleeve 14. It should be noted that the limiting arc plate portion 48 and the openings in the limiting arc plate portion 48 have a length sufficient for the anti-entanglement sleeve 14 to move outside the guide inner rod 15, and the front end of the guide inner rod 15 is penetrated on the inner side of the rear cover warehouse plate 17, and the rear cover warehouse plate 17 is fixedly provided on the outer wall of the tail of the propeller shell 1, and the limiting arc plate portion 48 and the rear cover warehouse plate 17 are oppositely distributed about the center point of the water inlet 7, and the design is as follows Figure 2 As shown, the top of the guide inner rod 15 is extended outward through the side of the rear cover compartment plate 17, and at the same time, a disassembly block 16 is fixed to the top of the guide inner rod 15. The surface of the disassembly block 16 is provided with screw holes corresponding to the screw holes on the surface of the rear cover compartment plate 17, so that the guide inner rod 15 can be stably placed on the inner side of the rear cover compartment plate 17;

[0053] Through the above-mentioned connection method, the guide inner rod 15 can be disassembled and then pulled out to one side from the rear cover compartment plate 17 to complete the disassembly. After the guide inner rod 15 is pulled out, the anti-entanglement sleeve 14 can move in the exit direction of the guide inner rod 15, and at the same time, the anti-entanglement sleeve 14 can be pulled out from the limiting arc plate portion 48. This method allows the subsequent anti-entanglement sleeve 14 and the guide inner rod 15 to be disassembled and replaced after they are severely worn.

[0054] like Figure 8As shown, a guide plate 30 is fixedly provided on the outer wall of the rear cover bin plate 17, a push plate 31 is slidably connected in the groove of the guide plate 30, a push link 32 is fixedly provided at the top of the push plate 31 near the opening of the rear cover bin plate 17, and a push arc plate 33 is fixedly provided at the bottom end of the push link 32, wherein the groove of the guide plate 30 is convex-shaped, so that the push plate 31 cannot be longitudinally separated from the groove of the guide plate 30, and the push link 32 is U-shaped, so that the front end of the push link 32 is bent and extends into the front position of the rear cover bin plate 17, and the push arc plate 33 is fixedly provided at the front end of the push link 32 It is worth noting that the arc of the push arc plate 33 is the same as the arc shape of the multiple groups of anti-entanglement sleeves 14, and the push arc plate 33 is located at the periphery of the anti-entanglement sleeve 14, that is, the push arc plate 33 and the lower support rod 34 fixed at the bottom of the lower support rod 34 will not affect the movement of the anti-entanglement sleeve 14, and the multiple groups of lower support rods 34 all extend inwardly. At the same time, the number of lower support rods 34 and the anti-entanglement sleeve 14 is kept consistent, and the distribution position of the lower support rods 34 and the distribution position of the anti-entanglement sleeve 14 are made the same, that is, one group of lower support rods 34 corresponds to one group of anti-entanglement sleeves 14.

[0055] In order to separate the fishing line wound around the anti-entanglement sleeve 14 from the surface of the anti-entanglement sleeve 14, the design is as follows Figure 8 , Fig. 9 As shown in the assembled top plate 10, an extension cross bar 35 is fixedly provided at the bottom of the lower support rod 34, so that the angle between the extension cross bar 35 and the lower support rod 34 is vertical, and a groove is provided at the front end of the extension cross bar 35, a rotatable shaft 36 is provided in the groove, and a hook rod 39 is fixedly provided on the outer wall of the shaft 36; the fishing line wound around the anti-entanglement sleeve 14 can be hooked out by the hook rod 39;

[0056] In order to complete the above operation, the surface of the anti-entanglement sleeve 14 is provided with sleeve slots 24 distributed in an annular array, that is, when the anti-entanglement sleeve 14 rotates and the fishing line is wound around the outside of the anti-entanglement sleeve 14 by the rotation of the anti-entanglement sleeve 14, due to the groove design of the sleeve slot 24, there will be a gap between the fishing line and the groove of the sleeve slot 24, and the hook rod 39 and the guide inclined groove 25 connected to the bottom of the hook rod 39 can extend into the groove of the sleeve slot 24. When the angle of the hook rod 39 is initially less than 90 degrees, when the anti-entanglement sleeve 14 is turned to When moving along the extension cross bar 35, the rotating shaft 36 and the hook rod 39 enter the groove of the sleeve slot 24, and the angle of the hook rod 39 is also pressed down, so that the extension cross bar 35 and the hook rod 39 gradually move toward the end of the anti-entanglement sleeve 14. On the contrary, when the anti-entanglement sleeve 14 moves in the opposite direction, the top of the hook rod 39 will hook the entangled fishing line, and then pull the fishing line out from the surface of the anti-entanglement sleeve 14, so that the fishing line is hooked in front of the rear cover compartment plate 17, reducing its influence on the water flow, and thus reducing the influence on the propulsion power of the entire propeller;

[0057] In order to maintain the tilt angle of the hook rod 39, an angle limit block 37 is fixedly arranged on the inner wall of the groove and closer to the end of the extended cross bar 35. A round hole is provided in the angle limit block 37 near the surface of the hook rod 39, and a spring part 1 38 is embedded in the round hole. The other end of the spring part 1 38 is connected to the hook rod 39. The hook rod 39 is limited by the angle limit block 37 so that the maximum angle of the hook rod 39 is kept less than 90°. When the hook rod 39 is pressed by the fishing line, the spring part 1 38 is forced to be stretched, that is, the spring part 1 38 gives the hook rod 39 a certain elastic force, so that the hook rod 39 can complete the tilting state in the subsequent process, thereby gathering the fishing line inside the angle between the hook rod 39 and the extended cross bar 35.

[0058] To further complete the above operations, Figure 4 , Figure 5 as well as Fig. 9 As shown, a directional groove 20 is provided in front of the groove of the thread groove 18, and the groove direction of the directional groove 20 is in the direction of the shaft of the guide inner rod 15, and the groove width of the directional groove 20 on one side close to the thread groove 18 is greater than the groove width on the other side of the directional groove 20, so that the moving block 19 enters the early stage of the directional groove 20, and has a certain left and right activity space, which is convenient for the subsequent extension cross bar 35 to enter the groove of the sleeve groove 24, that is, when the anti-entanglement sleeve 14 moves spirally to the front end position of the extension cross bar 35, the moving block 19 will enter the position of the directional groove 20, and due to the groove direction design of the directional groove 20, the anti-entanglement sleeve 14 is converted from a rotating shape to a linear direction movement, so when the sleeve groove 24 reaches the front end of the extension cross bar 35, the extension cross bar 35 and the hook rod 39 can smoothly enter the groove of the sleeve groove 24;

[0059] Two sets of guiding inclined grooves 25 are provided at the end of the sleeve slot 24. Figure 4 as well as Figure 6 As shown, the guide inclined grooves 25 distributed opposite to each other form an open V-shaped structure, that is, they play a guiding role for the extension cross bar 35. When there is a deviation and dislocation of movement, the front end of the extension cross bar 35 can enter the groove of the sleeve slot 24 along the inclined surface of the guide inclined groove 25 through the inclined surface of the guide inclined groove 25;

[0060] It is worth noting that the length of the hook rod 39 is greater than the depth of the sleeve slot 24. When the anti-entanglement sleeve 14 moves in the reverse direction, the hook rod 39 can touch the fishing line on the surface of the anti-entanglement sleeve 14 to complete the work of retracting the fishing line.

[0061] like Figure 6As shown, a perforation is provided on the surface of the anti-entanglement sleeve 14. As shown in the figure, a sleeve side groove 29 connected to the perforation is provided on the surface of the anti-entanglement sleeve 14, and a supporting cross plate 8 is installed in the sleeve side groove 29. A winding protrusion block 27 placed in the perforation is fixed on the surface of the supporting cross plate 8, that is, the winding protrusion block 27 is placed in the perforation, and the winding protrusion block 27 and the sleeve slot 24 are distributed in an annular manner. The winding protrusion block 27 with a raised design can further play a better winding effect on the fishing line and the silk thread when the anti-entanglement sleeve 14 rotates, and the winding protrusion block 27 and the protrusion connecting rod 28 can also be retracted into the sleeve side groove 29 and the perforation to avoid affecting the collection work of the hook rod 39 on the fishing line and the silk thread;

[0062] In order to prevent the winding protrusion block 27 from being completely sunken into the through hole, so that the winding protrusion block 27 can protrude from the through hole without affecting the work of the hook rod 39 to collect the fishing line, the support connecting rod 13 is designed as shown in the figure, and a mounting cross plate portion 44 is provided at the bottom of the sleeve side groove 29, and a plurality of sets of spring portions 45 are connected to the upper part of the mounting cross plate portion 44, and a circular support plate 46 is fixed on the top of the spring portion 45, and an outer sleeve ring plate 47 is fixed on the outer side of the circular support plate 46; the number and position of the spring portions 45 are equal to the winding protrusion block 27;

[0063] When in use, the arc-shaped bottom of the installation horizontal plate portion 44 is slid along the bottom of the sleeve side groove 29 into the hole of the sleeve side groove 29 and extended out, and finally the rotating shaft 36 is cushioned at the bottom of each winding protrusion block 27. Through the elastic action of the second spring portion 45, the circular support plate 46 provides a certain upward support capacity for the bottom of the winding protrusion block 27. At the same time, when the hook rod 39 retracts the fishing line, the side of the winding protrusion block 27 is designed to be an inclined surface. The displacement of the fishing line can also force the winding protrusion block 27 to be pressed down and retracted into the perforation. At the same time, the second spring portion 45 can be further compressed;

[0064] In order to further facilitate the installation and disassembly of the transverse plate portion 44, the design is as shown in the supporting connecting rod 13, and a group of truncated cone-shaped hollow outer sleeve ring plates 47 are arranged on the periphery of the spring portion 45, that is, the side surface of the outer sleeve ring plate 47 is an inclined surface. When the installed transverse plate portion 44 is pushed inward at the bottom of the groove of the sleeve side groove 29, the inclined surface of the outer sleeve ring plate 47 can lift the bottom of the winding protrusion block 27 to reduce the jamming. In addition, corresponding screw holes are arranged on the end face of the installed transverse plate portion 44 and the end face of the anti-entanglement sleeve 14. After the installation of the installed transverse plate portion 44 is completed, the installed transverse plate portion 44 and the anti-entanglement sleeve 14 are reinforced and combined with gaskets and screws.

[0065] like Figure 6 as well as Figure 7As shown, a connecting ring 21 is fixedly provided on the end face of the anti-entanglement sleeve 14, and another group of reinforcing connecting plates 23 are provided. The surface of the reinforcing connecting plates 23 also has assembly holes 22, and the assembly holes 22 are sleeved outside the connecting ring 21. The number of the assembly holes 22 corresponds to that of the connecting ring 21, and the arc-shaped distribution position of the assembly holes 22 corresponds to the position of the connecting ring 21. Through the reinforcing connecting plates 23 and the connecting ring 21, multiple groups of anti-entanglement sleeves 14 can be further connected to enhance the stability of the multiple groups of anti-entanglement sleeves 14.

[0066] As shown in the electric screw 11 and the plug-in connecting rod 12, a slide groove is provided on the surface of the rear cover warehouse plate 17 located below the push plate 31, and an extension probe block 40 is inserted into the slide groove. Two sets of directional wheels 41 are provided in the cavity of the rear cover warehouse plate 17, and the surfaces of the two sets of directional wheels 41 are wound with synchronous belts 42; the two sets of directional wheels 41 are rotatably connected to the rear cover warehouse plate 17, and the two sets of directional wheels 41 are respectively located at the front and rear sides of the opening of the slide groove, and the spacing between the two sets of directional wheels 41 is greater than the groove length of the slide groove; a guide groove is provided on the surface of the rear cover warehouse plate 17 located on one side of the directional wheel 41, and a trigger block 43 is connected in the guide groove, and the ends of the trigger block 43 and the extension probe block 40 are respectively connected to the synchronous belt 42;

[0067] When in use, an upward projection is fixedly provided at the center of the surface of the assembly sleeve hole 22 connected to the connecting ring 21, and the projection can abut against the surface of the lower support rod 34 after entering the inner side of the rear cover warehouse plate 17. The above-mentioned advantage is that when the anti-entanglement sleeve 14 pushes the reinforcement connecting plate 23 to move, the projection can push the trigger block 43 to move, and the movement of the trigger block 43 can pull the synchronous belt 42, so that the synchronous belt 42 rotates around the directional wheel 41, thereby making the extension probe block 40 connected to the synchronous belt 42 move in the slide groove of the rear cover warehouse plate 17, so that the pushing plate 31 can push the multiple groups of lower support rods 34 and the extension cross bar 35 to move forward, combined with the above, so that the extension cross bar 35 can move in the direction away from the rear cover warehouse plate 17 and enter the groove of the sleeve slot 24; so that the hook rod 39 and the extension cross bar 35 can actively enter the groove of the sleeve slot 24;

[0068] It is worth noting that the movement of the arc plate 33 and the reinforcement link plate 23 triggering the trigger block 43 to drive the synchronous belt 42 to move are all carried out when the moving block 19 moves in the groove of the directional groove 20. When the moving block 19 rotates into the threaded groove 18, the extending cross bar 35 and the hook rod 39 have already pushed the fishing line away from the outside of the anti-entanglement sleeve 14 to the rear cover panel 17.
