As shown in fig. 1, 2 and 3, a pebble energy dissipation well comprises an energy dissipation well body 1. The top side wall of the energy dissipation well body 1 is communicated with a water inlet 2, and the bottom side wall of the energy dissipation well body 1 positioned on the opposite side of the water inlet 2 is communicated with a water outlet 3. The bottom of the energy dissipation well body 1 is also provided with a plurality of pebbles 5, and the pebbles 5 can form a pebble layer, so that water flow falling from the water inlet 2 can be firstly impacted on the pebble layer to dissipate energy, and then is discharged from the water outlet 3. In addition, the pebble layer can ensure the fluency of water flow when dissipating energy to the water flow, and the slit in the pebble layer can also intercept sediment brought by drainage water flow, so that the sediment effect is achieved on a downstream net pipe.

It will be appreciated that with the use of pebble layers for a long period of time, the pebble layers may wear out resulting in poor energy dissipation or impurities adhering to the pebble layers resulting in reduced mud settling effects, which require replacement or cleaning of the pebble layers. And in order to be convenient for change and washing in order to improve the maintainability of pebble energy dissipation well to pebble layer, this disclosure is provided with mounting plate 4 in the bottom of energy dissipation well body 1, and above-mentioned a plurality of pebbles 5 are placed in mounting plate 4, and still are provided with connecting portion 6 on the mounting plate 4, can dismantle through connecting portion 6 and be connected with spliced pole 7, and this spliced pole 7 extends to the well head one side of energy dissipation well body 1. So, when the pebble layer needs to be changed, the staff can install spliced pole 7 on connecting portion 6, can together put forward from the energy dissipation well body 1 with a plurality of pebbles 5 of mounting disc 4 intercommunication through promoting spliced pole 7 afterwards, and then can be convenient change the pebble layer. Wherein the lifting of the connecting column 7 may use manual or hoisting machinery.

Preferably, the diameter of the pebbles 5 constituting the pebble layer is 5-10mm and the layer thickness of the pebble energy dissipation layer is 0.3-0.5m. The pebble energy dissipation layer can have better energy dissipation performance, and the quality of the pebble energy dissipation layer is not easy to be too large, so that the installation disc 4 is not easy to be lifted out of the well body.

Further, the connecting post 7 may be formed by sequentially connecting a plurality of rod bodies, for example, the rod bodies may be connected by screw threads. And the top of spliced pole 7 (i.e. the body of rod that is located the top) is provided with gripping portion 9, and staff's accessible gripping portion 9 is convenient, laborsaving with spliced pole 7 follow the well body and put forward. Preferably, the grip 9 comprises several grip bars circumferentially arranged at the side walls of the connecting column 7.

In some embodiments, the connecting portion 6 includes a connecting seat disposed on the mounting plate 4, a connecting hole 8 is formed on a top surface of the connecting seat, the connecting hole 8 is configured with internal threads, and an external thread is configured at a bottom of the connecting column 7, so that detachable connection between the connecting column 7 and the connecting seat can be achieved through screwing of the internal thread and the external thread. Alternatively, the connection portion 6 may be a first hook (not shown), and the bottom of the connection post 7 is correspondingly provided with a second hook (not shown), so that the connection post 7 and the mounting disc can be detachably connected by hooking the two hooks.

In addition, in order to improve the service life of the pebble energy dissipation layer, the present disclosure further designs the mounting disc 4 to include a main body 10 and a rotating portion 11 rotatably connected to the main body 10, for example, a rotating shaft is provided at the center of the main body 10 (and may be configured as the connecting portion 6 described above, i.e., the top of the rotating shaft may be provided with the connecting hole 8), the rotating portion 11 is configured as a shape having a rotating hole provided at the center and having a circumferential stop, the rotatable of the rotating portion 11 relative to the main body 10 may be achieved through the cooperation of the rotating hole and the rotating shaft, and the pebbles 5 are placed in the circumferential stop configuration of the rotating portion 11. Therefore, it can be understood that the rotating portion 11 after rotation can change the position of the pebble layer at the drop point of the water flow, so as to avoid the situation that the pebble layer is impacted with the water flow at the same position for a long time. Or, after the energy dissipation of the water flow is carried out on one position of the pebble layer for a preset period, the worker can rotate the rotating part 11 to change the new energy dissipation positions of the pebble layer and the water flow, so that the pebble layer can be fully and comprehensively utilized, and the service life is prolonged.
