[0028] An electric push rod 3 is installed on the inner top wall of the frame 1, and the output end of the electric push rod 3 is fixedly connected to a connecting ring 4, and the bottom surface of the connecting ring 4 is fixedly connected to the upper surface of the rotating motor 201.

[0029] The inner top wall of the frame 1 is fixedly connected with a slide cylinder 5, and the inner wall of the slide cylinder 5 is sleeved with a slidable slide column 6, and the lower end of the slide column 6 is fixedly connected to the upper surface of the rotating motor 201.

[0030] Two slide grooves 7 are provided on the outer surface of the frame 1, and two slide rods 8 sliding on the inner wall of the slide groove 7 are fixedly connected to the left side of the rotating motor 201, and the left end of the slide rod 8 is fixedly connected to a limit ring 9.

[0033] Example 2

[0034] like Figure 3-4 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that the outer surface of the mounting ring 204 is provided with a ring-shaped array of connecting grooves 205, and the inner wall of the connecting groove 205 is hinged with a rotatable connecting rod 206 through a pin shaft, the right side of the mounting ring 204 is fixedly connected with a guide rod 207, and the outer surface of the guide rod 207 is sleeved with a slidable slip ring 208, the connecting block on the outer surface of the slip ring 208 is hinged with a ring-shaped array of transmission plates 209, and the end of the transmission plate 209 away from the slip ring 208 is hinged to the connecting block on the outer surface of the connecting rod 206, the outer surface of the guide rod 207 is sleeved with a telescopic spring 2010, and a push leaf 2011 is installed on the upper end of each connecting rod 206, and the outer surface of the connecting rod 206 is slidably connected to the reserved groove on the outer surface of the mounting cylinder 203.

[0035] In this embodiment, reference Figure 3 and Figure 4The installation ring 204 can facilitate the displacement of the push leaf 2011 after being impacted through the connecting groove 205 and the connecting rod 206, and the push leaf 2011 and the connecting rod 206 can be displaced through the transmission when the displacement occurs.

[0036] The plate 209 pushes the slip ring 208 to slide in the guide rod 207, so that the slip ring 208 squeezes the telescopic spring 2010, thereby buffering the push leaf 2011, and can reset after buffering, and can also avoid position displacement after encountering a collision.

[0037] One end of the guide rod 207 away from the mounting ring 204 is fixedly connected to the limiting plate 2012, and the right side surface of the limiting plate 2012 is fixedly connected to the inner wall of the mounting tube 203. By setting the limiting plate 2012, the telescopic spring 2010 can be better protected, and the stability of the mounting ring 204 and the mounting tube 203 during rotation can be improved, thereby preventing the mounting ring 204 from shaking and deflecting in the mounting tube 203, which affects the stability of the overall device, thereby greatly improving the practicability of the overall device.

[0038] The left end of the telescopic spring 2010 is fixedly connected to the outer surface of the slip ring 208, and the right end of the telescopic spring 2010 is fixedly connected to the outer surface of the limit plate 2012. By setting the limit plate 2012, the telescopic spring 2010 can be better limited and blocked, and the telescopic spring 2010 can be prevented from deviating and deviating from the motion trajectory during operation, which greatly improves the position stability of the telescopic spring 2010, thereby further improving the buffering effect of the telescopic spring 2010 on components.

By setting the blocking ring 2013, the slip ring 208 can be better limited and blocked when sliding horizontally, thereby preventing the slip ring 208 from driving the transmission plate 209 to move horizontally due to excessive angle deviation, which affects the transmission work of the transmission plate 209, thereby greatly improving the practicality and use effect of the overall device.

[0040] Working principle: When the whole device is pushed, the whole device is first installed through the mounting plate 10, and the electric push rod 3 is started, and the electric push rod 3 adjusts the height of the buffer mechanism 2 through the connecting ring 4. After the height adjustment is completed, the rotating motor 201 is started, and the output shaft of the rotating motor 201 drives the rotating rod 202 to rotate, so that the rotating rod 202 drives the installation cylinder 203, the installation ring 204 and the pushing blade 2011 and other components to rotate synchronously, so that the pushing blade 2011 can achieve the pushing effect. When the object or water flow is impacted, the push leaf 2011 is tilted at the mounting ring 204 through the connecting rod 206, and then the transmission plate 209 is driven by the connecting rod 206 to push the slip ring 208 to slide within a limited position at the guide rod 207, so that the slip ring 208 squeezes the telescopic spring 2010, and the telescopic spring 2010 provides a buffering force to buffer the impact force, thereby avoiding damage to the device components caused by excessive impact of objects or water flow, and avoiding the position displacement of the device components after the impact, thereby greatly improving the practicality and safety of the overall device.
