At this time, because the thrust of the water flow is smaller than the elastic force of the first spring 9, the elastic force of the first spring 9 pushes the shift lever 8 to rotate reversely, so as to drive the limiting rod 10 to move, and the movement is stopped after the limiting rod 10 is attached to the surface of the ditch body 1.
The flow of the water unit interval in irrigation canals and ditches body 1 is different to water is different with the impact force of swash plate 5, thereby makes swash plate 5 take place the intermittent amplitude rotation, and swash plate 5 indirectly drives fastening nut 26 rotatory and carries out zonulae occludens with the bolt, thereby indirectly improves the stability between two irrigation canals body 1 bodies, satisfies the user demand.
The arrangement of the first spring 9, the second spring 21-1, the third spring 28 and the fourth spring 16 plays an effective reset role, the normal work of the device is ensured, and the arrangement of the limiting rod 10, the limiting plate 29 and the limiting ring 30 plays a limiting role in limiting parts of the device.
According to the invention, the deflector rod is driven to move the gear transmission assembly through the impact force of water flow, so that the fastening nut is screwed, and the technical problem of inconvenience in checking looseness of the connecting bolt at the splicing part of the ditch in the prior art is solved. The invention can indirectly fix the fastening nut and the bolt by means of the thrust of water flow, and increases the stability between the fastening nut and the bolt, thereby indirectly improving the splicing stability between ditches, effectively preventing the phenomena of permeation or fracture, being not influenced by weather, avoiding the need of manually checking the tightness of the bolt, and reducing the labor intensity.
Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
