This contained angle can enough prevent that peripheral resident or staff error from falling into the long-pending oil bath, is difficult for falling down when guaranteeing again that the staff clears up long-pending oil bath. Moreover, the included angle is set to be 120-150 degrees, so that the oil accumulation pool ladder can be arranged conveniently, and oil products can be effectively prevented from overflowing.
Furthermore, an oil guide pipe through hole can be formed in the side wall surface of the oil accumulation pool. The oil discharge end of the oil guide pipe penetrates through the oil guide pipe through hole to be communicated with the bottom of one side wall surface of the oil accumulation pool.
Further, an installation groove is formed right above the oil guide pipe through hole and used for installing an alkane monitoring alarm. Leak integrative device of water conservancy diversion early warning interception still including dismantling the connecting piece, alkane monitoring alarm fixes in the mounting groove through dismantling the connecting piece.
For example, the alkane monitoring alarm can be installed in an installation groove on the wall surface of the oil accumulation pool, and the alkane monitoring alarm is installed on the cement surface of the oil accumulation pool installation groove through a shooting nail so as to prevent the alarm from being damaged by the bad weather or the personnel. When the oil pipeline leaks, the alkane monitoring alarm can monitor alkane steam volatilized when oil products leak from the oil discharge port of the oil guide pipe at the first time, and sends out an alarm signal to remind workers of timely maintaining and repairing the pipeline.
Further, the leakage, flow guiding, early warning and intercepting integrated device can further comprise a check sheet, the check sheet is rotatably connected to the oil discharging end, and oil products and/or rainwater in the oil accumulation pool can be prevented from flowing back to the oil guide pipe.
For example, the check sheet can be connected with the oil discharge end of the oil guide pipe through the spring inertia shaft, the check sheet rotates in a single direction, namely the check sheet can be pushed to flow into the oil accumulation pool in the process that leaked oil flows in the oil guide pipe, but oil or rainwater in the oil accumulation pool cannot push the check sheet to flow into the oil guide pipe. Therefore, the arrangement of the check sheet can effectively prevent oil products or rainwater in the oil accumulation pool from flowing back to the oil guide pipe.
Further, the leakage flow guide early warning and intercepting integrated device can further comprise a filtering mesh enclosure, and the filtering mesh enclosure is arranged on the oil collecting end and can separate solid particles from leaked oil. The filtering net cover is fixed at the oil collecting port of the oil guide pipe and is connected with the oil guide pipe. The filter screen cover is composed of composite carbon fiber, has strong toughness and high flexibility, is not easy to corrode after being placed underground for a long time, and has good sealing performance. The filter screen cover is used for separating solid particles and leaked oil products, and when oil spills in soil, the oil seeps, diffuses and collects into the oil guide pipe, impurities of solid mixtures are effectively separated, and the oil guide pipe is prevented from being blocked due to the fact that the oil guide pipe is filled into the soil.
