Embodiment Construction

[0009] As shown in Figure 1, a sealing rubber strip 8 is provided at the edge around the back of the grate body 1. This rubber strip can ensure that the turbid air under the grate body 1 does not escape through the four frames of the grate body and the contact surface of the grate seat. The strips can be bonded or embedded in the processed groove; the sealing sheet 5 is a thin sheet corresponding to the hole 6 on the grate to be blocked, which can block all the holes on the entire grate in a single piece. Corresponding seals can also be set for one row, several rows, one column, several columns or every two rows, one or several holes in a column, and around one or more holes corresponding to the seals on the back grate. Adhesive strip 8 is provided, and this adhesive strip can also be installed on the sealing sheet, which can ensure that the turbid air does not escape from the drain hole 6; in order to increase the strength of the sealing sheet, a rib-shaped object or Stamping...

Abstract

A kind of rain grate not gas blowsy upward wmposed by grate body, gasked ,mounting asis,asle bed,tosrioonal spring. and magnetic absorption. on the back of rain grate set movable caminar mounting corresponding to the let-down hold in the rain grate. The mounting connects to the mounting axis, the axis pierces into the axle bed hole blend wit the roan grate, and trosional spring set in the mounting axis, magnetic absorption is set on the mounting, sealed gasket is set in the grate body. When water fall down, and the waiter's gravity force the sealed mounting open downward. When the water let-down finished, the mounting will seal automatically because of magnetic suction or spring elasticity, and prevent the foul air to go up in the tube effectively.

Description

Technical field [0001] The invention relates to a rain grate used in municipal engineering, which can allow water to be discharged smoothly into a drainage pipe without hindering the passage of people and vehicles. Background technique [0002] At present, known rain grates are generally made of cast iron or cement. The orifice of the tunnel is not blocked by any means, and although it can meet the needs of draining water, it also causes the unpleasant smell formed in the underground pipeline to rise upwards, which is very inconsistent with the surrounding environment of the street market where people often move around. Invention content: [0003] This technical solution is designed to solve the problem of turbid air flowing upward under the rain grate. It completely separates the upper and lower spaces of the rain grate, prevents the smell from flowing upward, and at the same time does not hinder its original function of draining water and other functions. . [0004] Th...
