Problems solved by technology
However, on the one hand, such energy dissipation measures are prone to various complex hydraulic flow phenomena such as vortex, cavitation and cavitation, and aerated water flow in the shaft. Structural vibration problems, threats to structural safety
In addition, the inflow shaft is relatively high, the drop of water flow is large, and it has more potential energy. How to use this part of energy has not yet appeared in the current design of the inflow shaft of deep urban tunnels. Similar concepts and structures

Embodiment Construction
[0027] The specific structure of the energy dissipation and energy storage device applied to the water collection shaft in this embodiment is as follows: Figure 1-5 shown. Including the first water collecting plate 1, the second water collecting plate 2, the third water collecting plate 3, the fourth water collecting plate 4, the impact water runner blade 5, the first bevel gear 6, the second bevel gear 7, the rotating shaft 8. Power transmission main shaft 9 and gear pump 10.
[0028] Among them, the first water collecting plate 1 is a curved surface part inside the shaft after the parabola is stretched along a straight line. It can directly flow down the inner wall of the shaft at a relatively large flow rate and cause serious damage to the deep tunnel.
[0029] The second water collecting plate 2 is a curved surface obtained by sweeping a parabola along the half circle of the vertical shaft section, so as to reduce the impact on the water collecting plate when the water ...

The invention provides an energy dissipation and storage device for a deep drain tunnel inflow vertical shaft. The potential energy and kinetic energy of water flow flowing into the vertical shaft arestored by utilizing equipment in a deep tunnel drain system. The energy dissipation and storage device is characterized in that water flow entering the vertical shaft is centralized to an energy conversion device on one side of the vertical shaft through water collecting plates arranged in the vertical shaft, the water flow passes the water collecting plates and then impacts rotary wheel blades to drive a rotary wheel to rotate, two bevel gears are used to drive a rotary shaft so as to drive a force transmission spindle to rotate, the force transmission spindle can extend to the wellhead of the vertical shaft, and the force transmission spindle is connected with a gear pump at a position close to the wellhead to achieve hydraulic energy storage through the movement of gears. The energy dissipation and storage device has the advantages that the device is based on the working principle of energy conservation, the inflow energy of the vertical shaft is stored to provide energy for the operation of the whole system, and an energy dissipation effect is also achieved.
Description
technical field [0001] The invention relates to the technical field of urban deep tunnel drainage, in particular to an energy dissipation and energy storage device for vertical shaft inflow water flow, which is used to convert the energy of the water flow entering the vertical shaft into mechanical hydraulic energy and achieve the purpose of energy dissipation and energy storage. Background technique [0002] With the acceleration of urbanization in my country, the prominent rainwater problems brought about by the traditional urban construction model, such as frequent waterlogging, intensified runoff pollution, loss of water resources, and deterioration of the water ecological environment, have become one of the restrictive factors restricting social development. Today, with the increasingly saturated environmental carrying capacity, the construction of a "sponge city" has become an inevitable demand for the development of our country's society. In view of the characteristic...
