Problems solved by technology

[0003] In the mine water pipeline, the harm of water hammer is huge. It is easy to cause strong vibration of the pipeline, the pipe joint is disconnected, and water is poured into the mine channel, causing flooding. The pipe is collapsed and damaged, causing the pump to reverse and damage the pump room or pipeline, affecting production and construction safety
Existing water hammer removal generally adopts pressure relief or one-way buffering to reduce the pressure of water hammer, the cost is high, and the effect of water hammer removal is average

Abstract

The invention discloses a water hammer eliminating device for mine drainage. The water hammer eliminating device comprises a pipe body and flanges. The flanges are arranged on the end parts of the pipe body, and the pipe body is connected with a water pipeline through the flanges. Box bodies are arranged on the upper side and the lower side of the pipe body in a communicating mode, movable plates are arranged on the sides, close to the pipe body, in the box bodies, the movable plates are connected with buffering assemblies, and the buffering assemblies are connected with the inner walls of the box bodies; a piston ring is arranged on the inner wall of the pipe body, a rotating plate is arranged in the center of the piston ring, the rotating plate can rotate in the piston ring, a plurality of elastic assemblies are connected to one side of the piston ring, connecting blocks are connected to the other ends of the elastic assemblies, and the other ends of the connecting blocks are connected with the inner wall of the pipe body; and through the combined action of the elastic assemblies and the buffering assemblies, counter-acting force is repeatedly formed on a water hammer, the water hammer is eliminated, damage of the water hammer to the mine pipe body and a valve is reduced, normal production is guaranteed, and the water conveying safety of the mine pipeline is improved.

Description

technical field [0001] The invention belongs to the field of pipeline water delivery, in particular to a water hammer elimination device for mine drainage. Background technique [0002] The water hammer effect is a vivid statement. It refers to a serious water hammer caused by the water flow hitting the pipeline when the feed water pump starts and stops. Because inside the water pipe, the inner wall of the pipe is smooth, and the water flows freely. When the open valve is suddenly closed or the feedwater pump stops, the water flow will generate a pressure on the valve and the pipe wall, mainly the valve or the pump. Due to the smooth pipe wall, under the action of inertia of the subsequent water flow, the hydraulic force quickly reaches the maximum and produces damage. This is the "water hammer effect" in hydraulics, that is, positive water hammer. On the contrary, after the closed valve is suddenly opened or the feed water pump is started, water hammer will also be genera...
