Device for automatically emptying rain water in poison storage pool

Abstract

The invention discloses a device for automatically emptying rain water in a poison storage pool. The device comprises the poison storage pool, a water inlet pipe and an overflow pipe and an emptying pipe, wherein the water inlet pipe and the overflow pipe are communicated with the upper side wall of the poison storage pool; and the emptying pipe is communicated with the lower side wall of the poison storage tank and provided with a manual valve; the device is characterized in that: the top end of the piston storage pool is provided with a rain water signal bottle and is correspondingly provided with an automatic control box; the automatic control box is connected with the rain water signal bottle and the emptying pipe through a signal line on the automatic control box; the automatic control box is also connected with an electromagnetic valve on the emptying pipe through an electromagnetic valve control signal line on the automatic control box; and the automatic control box receives signals from the rain water signal bottle and the emptying pipe and sends a control signal to the electromagnetic valve on the emptying pipe so as to open or close the electromagnetic valve. The device can automatically open or close the valve on the emptying pipe after a rainfall to empty the rain water accumulated in the piston storage pool so as to save manual operation.

Description

Technical field [0001] The invention relates to a road and bridge longitudinal drainage and collection system in the field of environmental engineering, in particular to an automatic rainwater emptying device for a poison storage tank. Background technique [0002] In order to prevent liquid dangerous goods from polluting surface waters due to the leakage of dangerous goods caused by traffic accidents during road transportation, relevant environmental protection regulations require road bridges that cross sensitive water bodies (such as centralized drinking water source protection areas downstream of rivers) A longitudinal (along the length of the bridge) rainwater collection system should be built on both sides to introduce possible liquid dangerous goods leakage caused by traffic accidents into the collection tanks on both sides of the bridge. The collection tanks are also called poison storage tanks. Constructed by brickwork or reinforced concrete. The poison storage tank is ...

AI Technical Summary

Problems solved by technology

This bridge longitudinal drainage and collection system has played a positive role in reducing the risk of liquid dangerous goods traffic accidents and pollution of surface water bodies, but the defect is that it is necessary to manually empty the accumulated water in the poison storage tank every time it rains. It has the volume to accommodate possible hazardous material spills
