Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings. The embodiments described below by referring to the drawings are illustrative and intended to explain the present invention and should not be construed as limiting the invention.
The energy dissipation drop well of the embodiment of the present invention is described below with reference to the accompanying drawings. As shown in fig. 1 and 2, the energy dissipation drop well according to the embodiment of the present invention includes a drop well body 1, a water inlet pipe 2, a water outlet pipe 3, and an energy dissipation block 4.
The drop well body 1 extends along the upper and lower direction, and the top of drop well body 1 is equipped with the well head, and the top of drop well body 1 is equipped with the well lid 11 of closing cap well head. The water inlet pipe 2 is communicated with the drop well body 1, the water inlet pipe 2 is arranged at the upper part of the side of the drop well body 1, and the drainage flow of the water inlet pipe 2 is a first preset value. The water outlet pipe 3 is communicated with the drop well body 1, and the water outlet pipe 3 is arranged at the lower part of the side of the drop well body 1. Specifically, the water inlet pipe 2 is arranged at the upper end part of the side part of the drop well body 1, and the water outlet pipe 3 is arranged at the lower end of the side part of the drop well body 1. The water inlet pipe 2 and the water outlet pipe 3 are positioned on two sides of the drop well body 1 in the horizontal direction, and the water inlet pipe 2 and the water outlet pipe 3 extend along the horizontal direction. For example, the water inlet pipe 2 is located at the left side of the drop well body 1, the water outlet pipe 3 is located at the right side of the drop well body 1, and the water inlet pipe 2 and the water outlet pipe 3 extend in the left-right direction. The left-right direction and the up-down direction are shown by arrows in the figure.
The energy dissipation block 4 is arranged in the drop well body 1, and the energy dissipation block 4 is positioned between the water inlet pipe 2 and the water outlet pipe 3 in the up-down direction. The top surface of the energy dissipation block 4 and the inner wall surface of the drop well body 1 define an energy dissipation water tank 12, and water in the drop well body 1 fed by the water inlet pipe 2 can be fed into the energy dissipation water tank 12. Specifically, the energy dissipation block 4 is located in the drop well body 1 and can block the cavity of the drop well body 1 in the up-down direction, so that the top surface of the energy dissipation block 4 and the inner wall surface of the drop well body 1 define an energy dissipation water tank 12 capable of containing accumulated water. The drain may form a sink within the basin 12 to reduce the kinetic energy of the drain.
The energy dissipation block 4 is provided with an energy dissipation hole 41, an upper orifice of the energy dissipation hole 41 is formed in the top surface of the energy dissipation block 4 and is communicated with the energy dissipation water tank 12, and a lower orifice of the energy dissipation hole 41 is formed in the bottom surface of the energy dissipation block 4 and is communicated with the water outlet pipe 3, so that accumulated water in the energy dissipation water tank 12 can flow downwards into the water outlet pipe 3 through the energy dissipation hole 41.

Specifically, the drainage flow of the water inlet pipe 2 is a first preset value, and the through-flow section (less than or equal to a second preset value) of the energy dissipation hole 41 can be adjusted according to the drainage flow design of the water inlet pipe 2, so that the drainage of the water inlet pipe 2 is led into the energy dissipation water pool 12 to form an energy dissipation water pool and then is slowly discharged from the energy dissipation hole 41.

The diameter of each energy dissipating hole 41 is 8 mm or more and 20 mm or less, and the (total) through-flow cross section of the energy dissipating hole(s) 41 can be adjusted by adjusting the number of energy dissipating holes 41 on the energy dissipating block 4. Specifically, increasing the number of the energy dissipating holes 41 increases the area of the through-flow cross section so as to increase the total drainage flow of the energy dissipating holes 41 on the energy dissipating block 4. Reducing the number of energy dissipating holes 41 reduces the area of the through-flow cross section so as to reduce the total drainage flow of the energy dissipating holes 41 in the energy dissipating block 4.
