[0048] In one embodiment, Figure 1-4 As shown, the utility model provides a walking assembly, which is arranged on the hull 100, including two walking units symmetrically arranged on both sides of the hull 100, and the walking unit includes a paddle wheel 210, a motor 220, a first transmission wheel 230, a second transmission wheel 240, a transmission member 250 and an overload protection structure.

[0049] The paddle wheel 210 is rotatably connected to the hull 100. The motor 220 is fixedly mounted on the hull 100. The first transmission wheel 230 is rotatably arranged on the hull 100, and the first transmission wheel 230 is transmission-connected to the power output shaft of the motor 220. The second transmission wheel 240 is coaxially sleeved on the power input shaft of the paddle wheel 210, and the second transmission wheel 240 is transmission-connected to the power input shaft. The transmission member 250 is annular, and the transmission member 250 is sleeved on the first transmission wheel 230 and the second transmission wheel 240 and can rotate with the rotation of the first transmission wheel 230 and / or the second transmission wheel 240. In one embodiment, the first transmission wheel 230 and the second transmission wheel 240 are pulleys, and the transmission member 250 is a transmission belt adapted to the first transmission wheel 230 and the second transmission wheel 240. In another embodiment, the first transmission wheel 230 and the second transmission wheel 240 are sprockets, and the transmission member 250 is a transmission chain adapted to the first transmission wheel 230 and the second transmission wheel 240.

[0050] The overload protection structure is used to transfer the power of the motor 220 to the paddle wheel 210 when the load at the output end of the power output shaft of the motor 220 is within a preset range, and to interrupt the power transmission between the motor 220 and the paddle wheel 210 when the load at the output end of the power output shaft of the motor 220 exceeds a preset range.

[0051] During use, when the paddle wheel 210 is entangled by aquatic plants and cannot rotate, the load on the output end of the power output shaft of the motor 220 will increase and exceed the preset value. Under the action of the overload protection structure, the power transmission between the motor 220 and the paddle wheel 210 will be interrupted, thereby protecting the motor 220 from damage due to overload.

[0052] In one embodiment, the second transmission wheel 240 can perform reciprocating linear motion between a first position and a second position along the axial direction of the power input shaft.

[0053] The overload protection structure includes a third transmission wheel 261 , a fourth transmission wheel 262 and a first elastic member 263 .

[0054] The third transmission wheel 261 is arranged on one side of the second transmission wheel 240, and the third transmission wheel 261 is coaxially sleeved on the power input shaft and fixedly connected to the power input shaft. The fourth transmission wheel 262 is arranged on the side of the second transmission wheel 240 facing the third transmission wheel 261, and the fourth transmission wheel 262 is coaxially sleeved on the power input shaft, and the fourth transmission wheel 262 is fixedly connected to the second transmission wheel 240.

[0055] The first elastic member 263 is sleeved on the power input shaft, and in a natural state, the first elastic member 263 has a tendency to make the second transmission wheel 240 approach the third transmission wheel 261. In one embodiment, the first elastic member 263 is a spring.

[0056] Among them, when the second transmission wheel 240 is in the first position, the third transmission wheel 261 conflicts with the fourth transmission wheel 262, so that the fourth transmission wheel 262 can drive the third transmission wheel 261 to rotate. Specifically; when the second transmission wheel 240 is in the second position, the third transmission wheel 261 is separated from the fourth transmission wheel 262, so that the fourth transmission wheel 262 cannot drive the third transmission wheel 261 to rotate, thereby achieving the purpose of disconnecting the power transmission between the motor 220 and the paddle wheel 210.

[0057] During use, under normal circumstances, under the action of the elastic force of the first elastic member 263, the first elastic member 263 keeps the second transmission wheel 240 in the first position, so that the third transmission wheel 261 conflicts with the fourth transmission wheel 262, and the fourth transmission wheel 262 can drive the third transmission wheel 261 to rotate. When the paddle wheel 210 is entangled by water plants and cannot rotate, the load at the output end of the power output shaft of the motor 220 increases and exceeds the preset value, and the third transmission wheel 261 will collide with the fourth transmission wheel 262, thereby protecting the motor 220 from damage due to overload.

[0058] In one embodiment, a limiting groove is provided on the side of the fourth transmission wheel 262 facing the third transmission wheel 261, and guide slopes 203 are provided on both sides of the limiting groove. A limiting portion 201 adapted to the limiting groove is provided on the side of the third transmission wheel 261 facing the fourth transmission wheel 262.

[0059] When the second transmission wheel 240 is in the first position, the third transmission wheel 261 is meshed with the fourth transmission wheel 262, that is, the limiting portion 201 is located in the limiting groove 202. When the second transmission wheel 240 is in the second position, the third transmission wheel 261 is separated from the fourth transmission wheel 262, that is, the limiting portion 201 is separated from the limiting groove 202.

[0060] During use, under normal circumstances, under the action of the elastic force of the first elastic member 263, the first elastic member 263 maintains the second transmission wheel 240 in the first position, so that the limiting portion 201 is located in the limiting groove 202, and the motor 220 drives the fourth transmission wheel 262 to rotate. Under the action of the limiting portion 201 and the limiting groove 202, the fourth transmission wheel 262 can drive the third transmission wheel 261 to rotate, thereby achieving the purpose of driving the paddle wheel 210 to rotate.

[0061] When the paddle wheel 210 is entangled by aquatic plants and cannot rotate, the load at the output end of the power output shaft of the motor 220 increases and exceeds the preset value. Under the action of the guide ramp 203, the third transmission wheel 261 will drive the third transmission wheel to move through the guide ramp 203, thereby driving the second transmission wheel 240 from the first position to the second position, thereby achieving the purpose of disconnecting the power transmission between the motor 220 and the paddle wheel 210.

[0062] The overload protection structure of this structure is simple in structure and reasonably designed. By setting a limiting groove 202 on the fourth transmission wheel 262 and setting a limiting portion 201 on the third transmission wheel 261 that is compatible with the limiting groove 202, the reliability of power transmission between the fourth transmission wheel 262 and the third transmission wheel 261 is improved.

[0063] In one embodiment, the travel unit further includes a locking structure, which has an unlocked state and a locked state. When the locking structure is in the locked state, the locking structure locks the second transmission wheel 240 in the second position.

[0064] When in use, when the load at the output end of the power output shaft of the motor 220 exceeds a preset value, the third transmission wheel 261 drives the fourth transmission wheel 262 to move through the guide ramp 203, thereby driving the second transmission wheel 240 from the first position to the second position. Under the action of the locking structure, the locking structure locks the second transmission wheel 240 in the second position, thereby achieving the purpose of keeping the power transmission between the motor 220 and the paddle wheel 210 disconnected, thereby achieving the purpose of avoiding excessive wear of the third transmission wheel 261 and the fourth transmission wheel 262.

[0065] In one embodiment, the locking structure includes a slider 271 , a locking pin 272 and a second elastic member 273 .

[0066] The slider 271 is sleeved on the power input shaft, the slider 271 is rotatably connected to the second transmission wheel 240, the slider 271 is slidably connected to the hull 100, and the slider 271 has a locking socket 204. The locking pin 272 is slidably connected to the hull 100, and the locking pin 272 can reciprocate linearly between the third position and the fourth position in the direction of approaching or moving away from the locking socket 204, wherein when the locking pin 272 is in the third position, the locking structure is in a locked state, that is, the locking pin 272 enters and exits the locking socket 204. When the locking pin 272 is in the fourth position, the locking structure is in an unlocked state, that is, the locking pin 272 is separated from the locking socket 204. The second elastic member 273 is sleeved on the locking pin 272, and in a natural state, the second elastic member 273 has a tendency to make the locking pin 272 move from the fourth position to the third position.

[0067] When in use, in a normal state, the locking latch 272 is placed in the fourth position, and under the action of the elastic force of the first elastic member 263, the second transmission wheel 240 is located in the first position. When the load at the output end of the power output shaft of the motor 220 exceeds a preset value, the third transmission wheel 261 drives the fourth transmission wheel 262 to move through the guide ramp 203, thereby driving the second transmission wheel 240 from the first position to the second position. At this time, the locking socket 204 corresponds to the locking latch 272. Under the action of the elastic force of the second elastic member 273, the locking latch 272 is inserted into the locking socket 204, thereby achieving the purpose of locking the second transmission wheel 240 in the second position.

[0068] In one embodiment, the walking unit further includes a tensioning structure, which includes a mounting frame 281, a tensioning wheel 282 and a torsion spring.

[0069] The first end of the mounting frame 281 is hinged to the hull 100, and the second end is freely extended. The tensioning wheel 282 is arranged at the second end of the mounting frame 281 and is rotatably connected to the mounting frame 281, and the circumferential wall of the tensioning wheel 282 is in conflict with the transmission member 250. The torsion spring is arranged at the hinge center of the mounting frame 281, and in a natural state, the torsion spring has a tendency to keep the tensioning wheel 282 in conflict with the transmission member 250.

[0070] In one embodiment, the utility model further provides an unmanned operation vessel for feeding and applying medicine in aquaculture, comprising a hull 100, a feeding assembly and a medicine applying assembly arranged on the hull 100, and also comprising the walking assembly described in any of the above embodiments.

[0071] In this embodiment, a tensioning structure is provided to facilitate the movement of the second guide wheel.

However, it is understood that the embodiments of the present utility model can be practiced without these specific details. In some examples, well-known methods, structures and techniques are not shown in detail so as not to obscure the understanding of this specification.
