Drainage energy dissipation well

Abstract

The invention relates to a drainage energy dissipation well which comprises an upper well cavity formed by sequentially connecting a water distribution chamber, a water inlet chamber, a water passing chamber and a transition chamber, a lower well cavity composed of a water falling chamber, a sliding mechanism and a driving mechanism. The water inlet chamber and the water passing chamber are separated through the sliding mechanism, the driving mechanism is arranged in the driving chamber and connected with the sliding mechanism, the water falling chamber is located on the lower portion of the water passing chamber, an orifice communicated with the water falling chamber is formed in the bottom of the water passing chamber, the water distribution chamber is communicated with the water inlet pipe, and the side wall of the bottom of the water falling pipe is communicated with the water outlet pipe. According to the drainage energy dissipation well, classified energy dissipation of water flow kinetic energy and potential energy is achieved, the energy dissipation effect is improved, the internal space of the energy dissipation well is fully utilized, the problems that the energy dissipation effect is poor and the flow state in the well is disordered due to the fact that a traditional energy dissipation well conducts centralized and one-time large-drop water drop energy dissipation on all incoming water are solved, and the well body structure is protected.

Description

technical field [0001] The invention relates to the technical field of municipal drainage supporting facilities, in particular to a drainage energy dissipation well. Background technique [0002] Drainage and energy dissipation well is one of the important facilities in the municipal drainage pipe network system. Its main function is to dissipate the water from the drainage pipe with higher elevation upstream and then discharge it into the drainage pipe with lower elevation downstream to reduce the amount of water entering the downstream drainage pipe. The flow rate of the pipeline reduces the impact on the downstream drainage network system. The traditional energy dissipation method of drainage and energy dissipation well is to dissipate all the incoming water from the upstream drainage pipeline in a centralized, large drop, and one-time drop. This energy dissipation method mainly has the following problems: (1) It is not specially eliminated. The kinetic energy of the wat...

[0005] The beneficial effects of the present invention are: the drainage and energy dissipation well of the present invention divides the incoming water flow into the water inlet chamber and the water passage chamber through the water distribution chamber to form the main water flow and the branch water flow, and at the same time use the sliding mechanism and the The driving mechanism adaptively absorbs the kinetic energy of the main water flow, and then the water flow enters the falling water chamber through the water inlet chamber and the water passage chamber and undergoes graded collisions to eliminate the potential energy of the water flow, realize the classified energy dissipation of the kinetic energy and potential energy of the water flow, and improve the Energy dissipation effect, which not only makes full use of the internal space of the energy dissipation well, but also solves the problem of poor energy dissipation and the flow state in the well caused by the centralized type of all incoming water in the traditional energy dissipation well and the one-time large drop water energy dissipation. At the same time, it avoids a large impact on the energy-dissipating well body by a one-time large drop of water and energy dissipation, and protects the structure of the well body
