Description
Technical Field
[0001] The utility model relates to the technical field of silent driving structures, in particular to a silent driving structure of an electric pleasure boat. Background Art
[0002] At present, electric cruise ships use power to drive motors, which then use the motors to drive rotating paddles to achieve the propulsion function of the ship. In order to reduce the noise caused by the motors and rotating paddles, the existing electric cruise ships set the motors underwater and use water to play a sound insulation role.
[0003] However, although this silent driving structure can achieve silence, when the motor fails, the rotating paddle board can no longer work, so that there is no other power source to drive the hull to move, which makes tourists at risk of being trapped in the lake, greatly reducing the tourists' play experience and bringing negative impact to the scenic spot. Therefore, a silent driving structure of an electric cruise ship is proposed to solve the above problem. Utility Model Content

DETAILED DESCRIPTION
[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0023] Reference Figure 1-6 A silent driving structure of an electric pleasure boat comprises a soundproof box 1 fixedly connected to the bottom end of the hull, a double-shaft motor 12 installed inside the soundproof box 1, and a rotating paddle board 3 driven by the double-shaft motor 12, wherein the output end of the double-shaft motor 12 is fixedly connected to a motor plug shaft 9, one end of the motor plug shaft 9 is plugged with a motor plug sleeve 2, one end of the motor plug sleeve 2 is fixedly connected to a driven sprocket 8, and one end of the driven sprocket 8 is fixedly connected to the rotating paddle board 3 through a connecting shaft;
[0024] It should be noted that: the dual-axis motor 12 cooperates with the motor plug-in shaft 9 and the motor plug-in sleeve 2 to drive the rotating paddle board 3 to rotate, thereby realizing the driving function of the hull;
[0025] It is worth noting that at this time, the handle plug-in shaft and the handle plug-in sleeve 7 are in a separated state, that is, the dual-axis motor 12 is in a normal working state, and the driving handle 11 will not rotate accordingly.
[0026] The surface of the connecting shaft is rotatably connected with a connecting plate 4, the top of the connecting plate 4 is rotatably connected with a driving sprocket 5, a rack belt 6 is connected between the driving sprocket 5 and the driven sprocket 8, one end of the driving sprocket 5 is fixedly connected with a handle plug-in shaft, the side wall of the hull is rotatably connected with a handle plug-in sleeve 7, one end of the handle plug-in sleeve 7 is fixedly connected with a driving handle 11, the inner bottom end of the hull is fixedly connected with a hull hollow seat 10, a two-way cylinder 14 is installed on the inner side of the hull hollow seat 10, the cylinder shafts at both ends of the two-way cylinder 14 are sealed and slidably arranged with the side wall of the hull, and one end of the cylinder shaft is fixedly connected to the connecting plate 4.
[0027] It should be noted that: when the dual-axis motor 12 fails, the two-way cylinder 14 is turned on, so that the connecting plates 4 on both sides are moved closer to each other, thereby driving the handle plug-in shaft and the handle plug-in sleeve 7 to be plugged in, and at the same time, the motor plug-in sleeve 2 and the motor plug-in shaft 9 are further plugged in, so that the limiting protrusion 15 is separated from the limiting groove 201. At this time, the motor plug-in shaft 9 and the motor plug-in sleeve 2 are independent of each other (the motor plug-in shaft 9 no longer drives the motor plug-in sleeve 2 to rotate). At this time, the driving handle 11 is used to cooperate with the active sprocket 5 and the driven sprocket 8 to drive the rotating paddle board 3 to rotate, thereby driving the hull to move, thereby avoiding tourists being trapped due to the failure of the dual-axis motor 12.
[0028] The radius of the driving sprocket 5 is smaller than the radius of the driven sprocket 8, and the end of the limiting protrusion 15 is smoothly arranged.
[0029] It is worth noting that the radius of the driving sprocket 5 is smaller than the radius of the driven sprocket 8, which can greatly reduce the force required by tourists to rotate the driving handle 11, thus playing a labor-saving role;
[0030] The end of the limiting protrusion 15 is smoothly arranged to facilitate the separation of the limiting protrusion 15 from the limiting groove 201 .
[0031] Telescopic grooves are provided inside the handle plug-in shaft and the motor plug-in shaft 9, and relatively set limit protrusions 15 are slidably connected to the inner sides of the telescopic grooves. Limit springs 13 are fixedly connected between the limit protrusions 15. Limit grooves 201 that are engaged with the limit protrusions 15 are provided on the inner walls of the motor plug-in sleeve 2 and the handle plug-in sleeve 7. An annular inner groove 202 that is adapted to the limit protrusion 15 is provided inside the motor plug-in sleeve 2, and the end of the limit protrusion 15 is in an arc shape.
[0032] It should be noted that when the motor plug-in sleeve 2 and the handle plug-in sleeve 7 are moved, the side wall of the limiting groove 201 or the inside of the handle plug-in sleeve 7 will push the end of the limiting protrusion 15 and compress it to the inside of the telescopic groove, thereby facilitating the connection between the handle plug-in shaft and the handle plug-in sleeve 7.
[0033] The bidirectional cylinder 14 is a prior art, and its model is SCD125x200. It can realize the function of driving the connecting plate 4 to move, and will not be described in detail here.
[0034] When the utility model is in use, the dual-axis motor 12 is used to drive the motor plug shaft 9 to rotate, and then the motor plug sleeve 2 is used to rotate, and the motor plug sleeve 2 drives the rotating boat paddle board 3 to rotate, so as to realize the driving function of the hull. At the same time, since the dual-axis motor 12 is arranged at the bottom of the hull by using the sound insulation box 1, the good sound insulation function of the dual-axis motor 12 can be realized with the water, and the noise caused by the operation of the dual-axis motor 12 is greatly reduced;
[0035] When the dual-axis motor 12 fails, the two-way cylinder 14 can be turned on. The two-way cylinder 14 drives the moving plates to move toward each other, so that the connecting plates 4 on both sides move toward each other, and then drives the handle plug-in shaft and the handle plug-in sleeve 7 to be plugged in. At the same time, the motor plug-in sleeve 2 and the motor plug-in shaft 9 are further plugged in, so that the limiting protrusion 15 is separated from the limiting groove 201. At this time, the motor plug-in shaft 9 and the motor plug-in sleeve 2 are independent of each other (the motor plug-in shaft 9 no longer drives the motor plug-in sleeve 2 to rotate). At this time, the driving handle 11 is used to cooperate with the active sprocket 5 and the driven sprocket 8 to drive the rotating paddle board 3 to rotate (when the tourist rotates the driving handle 11, when the limiting groove 201 is aligned with the limiting protrusion 15, under the action of the limiting spring 13, the limiting protrusion 15 is engaged with the limiting groove 201, so that the handle plug-in shaft can drive the handle plug-in sleeve 7 to rotate), thereby driving the hull to move, avoiding the phenomenon that tourists are trapped due to the failure of the dual-axis motor 12.
[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
