Embodiment Construction

[0034] The technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention.

[0035] Please refer to figure 1 , figure 2 with image 3 , the embodiment of the present invention provides a rotating fast energy dissipation system for breach rescue, including an energy dissipation device and a fixed structure.

[0036] The energy dissipation device includes a rotating shaft 1, an impeller 2 and a bearing 3. The bearing 3 is installed at the head and tail of the rotating shaft 1, and the impeller 2 rotates around the rotating shaft 1 through the bearing 3. The rotating shaft 1 is a hollow metal shaft, and one end is provided with a connecting device 4 matching the holder 5, and the outer diameter is 100mm-300mm. The impeller 2 is a hollow cylinder with blades inside. The blades are symmetrically arranged around the central axis. The outer diameter of the impeller 2 is 1-2m. The...

Abstract

The invention provides a rotary fast energy dissipating system for breach rescue, which includes an energy dissipating device and a fixed structure. The energy dissipating device includes a rotating shaft, an impeller and a bearing. The impeller is connected to the rotating shaft through the bearing. The device and the fixer, the energy dissipation device is connected with the fixer through the connecting device, the fixer is used to fix the energy dissipation device in the water flow of the breach, the impeller rotates around the rotating shaft under the impact of the water flow to quickly consume the flow energy of the water flow, and has a horizontal and vertical layout. The invention also provides an application method of the rotary fast energy dissipation system used for breach rescue. The invention utilizes the water flow to impact the impeller to make it rotate to dissipate energy, which can greatly reduce the water head and flow velocity, and make it possible to block and intercept the flow at high flow velocity. It can work immediately after the installation is completed. The operation is simple, the layout is flexible, it is convenient to recycle, and it can be repeated. Utilization, environmental protection and conservation, remarkable economic and environmental benefits.

Description

technical field [0001] The invention relates to the technical field of emergency rescue, in particular to a rotary fast energy dissipation system and an application method for breach rescue. Background technique [0002] Embankment breach rescue needs to be carried out under dynamic water conditions. If the flow velocity of the water is too fast, the throwing material will be washed away, which will bring great difficulties to the blockage. The usual method is to wait for the water level difference to decrease, the flow velocity to slow down, or even the water levels on both sides of the embankment to be equal. Carry out blockage again, this will inevitably lead to the increase of rescue time, the disaster-stricken time prolongs, and causes bigger economic loss. [0003] Traditional breach rescue uses wooden piles and throwing materials to block the opening, but when the flow rate at the throwing point is too fast, the piling operation cannot be carried out, and at the same ...
