Specifically, the water wheel driving assembly 4 includes an impeller 41, a turntable 42 and a connecting rod 43; the impeller 41 is arranged in the fixed pipe body 1, and the impeller 41 is impacted by water flowing through the fixed pipe body 1 to rotate; the rotary disc 42 is arranged outside the fixed pipe body 1, and the rotary disc 42 is coaxially connected with the impeller 41 and synchronously rotates along with the impeller 41; one end of the connecting rod 43 is hinged with the surface of the turntable 42 and is far away from the center of the turntable 42, and the other end of the connecting rod 43 is provided with a linkage part 3; the impeller 41 receives the hydraulic impact flowing through the fixing pipe 1 to rotate, and drives the rotary table 42 to rotate synchronously, so that the link 43 pulls or pushes the linkage part 3 to move. Wherein the turntable 42 rotates along a horizontal axis.
Meanwhile, since the swinging pipe body 2 swings left and right at the same time as pitching, the linkage portion 3 actually rotates not only around the horizontal line along with the swinging pipe body 2 but also around the vertical line along with the swinging pipe body 2, and thus the angle between the projection of the linkage portion 3 on the horizontal plane and the link 43 changes.

Meanwhile, in order to fix the pitch angle of the swing pipe body 2, the locking assembly 5 is disposed on the fixed pipe body 1 and connected to the linkage portion 3, and the locking assembly 5 is used to prevent the linkage portion 3 from moving relative to the fixed pipe body 1, so that the swing pipe body 2 performs a reciprocating swing in the left and right directions while the extending direction of the swing pipe body 2 is maintained at the same pitch angle with the horizontal plane.
Specifically, as shown in fig. 1 and in conjunction with fig. 2, the locking assembly 5 includes a base 51, a bracket 52, a positioning sleeve 53, a screw 54 and a nut 55; the base 51 is arranged on the fixed pipe body 1; a holder 52 provided on the base 51, the holder 52 being axially rotatable in the plumb line direction with respect to the base 51; a positioning sleeve 53 is arranged on the end of the bracket 52 far away from the base 51, and the positioning sleeve 53 can axially rotate along the horizontal direction relative to the bracket 52; one end of the screw rod 54 is hinged with the linkage part 3, and the other end of the screw rod 54 passes through the positioning sleeve 53 and extends outwards; the nut 55 is screwed with the end part of the screw 54 extending outwards through the positioning table; when the pitch angle of the swinging pipe body 2 needs to be fixed, the nut 55 can selectively move relative to the screw 54 and abut against the positioning sleeve 53, so as to prevent the swinging pipe body 2 from tilting and bending under the action of self-weight, and thus, the included angle between the extending direction of the swinging pipe body 2 and the horizontal plane is kept unchanged.
The working principle is as follows:
water is fed from the inside of the fixed pipe body 1, flows into the swing pipe body 2, and is jetted.
The water impacts the impeller 41 to rotate the impeller 41 and drive the turntable 42 to synchronously rotate; the turntable 42 rotates, when the hinged position of the connecting rod 43 on the turntable 42 rotates to the position farthest from the swinging pipe body 2, the connecting rod 43 is driven to pull the linkage part 3 to move towards the direction close to the fixed pipe body 1, so that the front end of the swinging pipe body 2 is raised; when the hinged part of the connecting rod 43 on the turntable 42 rotates to the position nearest to the swinging pipe body 2, the connecting rod 43 is driven to push the linkage part 3 to move towards the direction far away from the fixed pipe body 1, so that the swinging pipe body 2 bends downwards; the turntable 42 is continuously rotated to repeat the above two operations alternately, thereby pitching the swinging pipe body 2 with respect to the horizontal plane.
