In the second embodiment, on the basis of the first embodiment, the buffering assembly 6 includes rotating rods 601 symmetrically installed inside the elbow 1, a side plate 602 is installed on one side of the rotating rod 601, buffering plates 603 are installed between the side plates 602 on both sides at equal intervals, a push rod 604 is installed at the bottom end of the side plate 602, the buffering plates 603 are arranged in an arc plate shape, the push rod 604 is arranged to be curved, and the push rod 604 is tightly attached to the inner bottom wall of the elbow 1;

after elbow 1 is gushed into inside from inlet tube 2 to rivers, rivers transversely strike on a plurality of buffer boards 603 of installation between two curb plates 602, because buffer board 603 is the arcuation, and buffer board 603 sets up more, thereby make rivers constantly strike on buffer board 603, thereby make buffer board 603 cushion rivers, make the impact force of rivers to elbow 1 inner wall reduce, thereby improve elbow 1's intensity.

In the third embodiment, on the basis of the second embodiment, a counterweight 606 is installed at one end of the push rod 604, a connecting block 609 is installed at the bottom end of the counterweight 606, a sliding block 610 is installed at the bottom end of the connecting block 609, a movable sliding groove 608 is connected to the bottom end of the sliding block 610 in a sliding manner, a fixed sliding groove 607 is connected to the bottom end of the movable sliding groove 608 in a sliding manner, the fixed sliding groove 607 is arranged on the inner bottom wall of the elbow 1, the length of the fixed sliding groove 607 is greater than that of the movable sliding groove 608, the width of the fixed sliding groove 607 is greater than the distance between the inner walls of the two sides of the elbow 1, the length of the counterweight 606 is greater than that of the sliding block 610, and radians are respectively arranged at the bottom end of the sliding block 610 and the bottom end of the counterweight 606;

when water flow impacts the buffer plate 603, a side plate 602 is rotationally connected with the rotating rod 601, thereby causing the side plate 602 to rotate downward, and the bottom end of the side plate 602 is connected with a weight block 606 through a push rod 604, when the side plate 602 rotates downward, the sliding block 610 at the bottom end of the weight block 606 is driven to move upward along the movable sliding groove 608, when the sliding block 610 moves to the top end of the movable sliding chute 608, the sliding block 610 cannot move upwards continuously, so that the counterweight 606 with the movable sliding chute 608 moves to slide upwards in the fixed sliding chute 607, and when the movable sliding chute 608 slides to the top end of the fixed sliding chute 607, since the length of the weight 606 is greater than the length of the slider 610, when the weight 606 moves to the topmost end, the top end of the weight 606 protrudes to the side of the water inlet pipe 2, so that when water flows into the elbow 1, impact one side of the counterweight 606 to cushion the water flow, further improving the strength of the elbow 1.

In the fourth embodiment, on the basis of the third embodiment, a connecting rod 605 is installed on one side of the side plate 602, one end of the connecting rod 605 is fixedly connected with the top end of the counterweight 606, the connecting rod 605, the push rod 604 and the side plate 602 form a triangular shape, and the connecting rod 605, the push rod 604 and the side plate 602 form a triangular shape, so that the fixing strength between the side plate 602 and the counterweight 606 is increased due to the stability of the triangular shape.

The working principle is as follows: when the water flow buffering elbow works, firstly, after water flows gush into the elbow 1 from the water inlet pipe 2, the water flows transversely impact a plurality of buffering plates 603 arranged between the two side plates 602, and the buffering plates 603 are arc-shaped, and the number of the buffering plates 603 is large, so that the water flows continuously impact the buffering plates 603, the buffering plates 603 buffer the water flows, and the impact force of the water flows on the inner wall of the elbow 1 is reduced;

when water flow impacts the buffer plate 603, a side plate 602 is rotationally connected with the rotating rod 601, so that the side plate 602 rotates downwards, the bottom end of the side plate 602 is connected with a balancing weight 606 through a push rod 604, when the side plate 602 rotates downwards, a sliding block 610 at the bottom end of the balancing weight 606 is driven to move upwards along a movable sliding groove 608, when the sliding block 610 moves to the top end of the movable sliding groove 608, the sliding block 610 cannot move upwards continuously, then the balancing weight 606 drives the movable sliding groove 608 to move upwards inside a fixed sliding groove 607, when the movable sliding groove 608 slides to the top end of the fixed sliding groove 607, because the length of the balancing weight 606 is greater than that of the sliding block 610, after the balancing weight 606 moves to the topmost end, the top end of the balancing weight 606 protrudes to one side of the water inlet pipe 2, and when the water flow enters the elbow 1, one side of the balancing weight 606 is impacted, so that the water flow is buffered;

when rivers strike on the balancing weight 606, this moment because rivers reduce the impact force of buffer board 603, promote balancing weight 606 migration simultaneously, then make the effect of self gravity of balancing weight 606 and rivers impact move back down, then make balancing weight 606 drive curb plate 602 migration back, continue to carry out cushioning effect to rivers at the in-process that buffer board 603 moved back fast, after rivers reduce, balancing weight 606 can be under the effect of self gravity, get back to the original position.
