TECHNICAL FIELD

[0001] The utility model relates to steel grating technical field especially relates to an environmental protection type steel grating with excellent permeability. BACKGROUND

[0002] In the early construction, industry and other fields, in order to meet the needs such as erecting simple platform, covering ditch and so on, people began to use simple strip metal material to splice, formed the most primitive plate with certain openwork structure, this can be regarded as the prototype of steel grating.These first generation "steel grating" only simply fixed metal strip in horizontal and vertical cross mode, although it can realize basic support and certain degree of ventilation, drainage function, but its structure is loose, poor stability, it is easy to deform or collapse when bearing external force, and the function is very single, can only be used in some temporary scenes with very low load bearing and permeability requirements.

[0003] But as for traditional equipment, traditional steel grating is mostly only composed of frame and simply cross-arranged steel plate, the structure is relatively single, although it has certain bearing capacity and basic permeability, but when facing complex working conditions, its functionality is insufficient.For example, when using steel grating as cover plate in some drainage systems, there is no effective filtering structure, various sundries, garbage can easily enter the pipeline with water flow, and day after day will cause pipeline blockage, affect the normal operation of the whole drainage system, subsequent cleaning not only time-consuming and laborious, but also may need to suspend the use of related facilities, bring many inconveniences.In the steel grating in some ventilation facilities, due to the lack of blocking and filtering mechanism, the dust, leaves and other foreign matters from outside are easy to enter the internal space, accumulate in the ventilation pipeline or equipment, reduce the ventilation efficiency, and even may affect the normal operation of the equipment, increase the maintenance cost and frequency, need to be improved.

Here, the number of spring one is four groups and every two groups is symmetrically distributed in the inside of plug-in groove, and the symmetrically distributed spring one can make the elastic force received by the slider in the plug-in groove more uniform, ensure that the slider drives the moving plug-in plate to move balancedly, avoid the situation that the moving is not smooth, jamming or component damage occurs due to unilateral excessive stress, ensure that the moving plug-in plate moves stably and accurately when limiting or releasing the limiting operation of the fixed block, improve the reliability and stability of the related operation in the process of filter plate installation and disassembly, prolong the service life of each component.

Here, the spring two is installed in the fixed cylinder, one end is connected and fixed with the inner surface of the fixed cylinder, and the other end is connected and fixed with the bottom end surface of the moving column. When the steel grating is subjected to external force and the moving column moves relative to the fixed cylinder, the spring two is compressed or stretched, storing elastic potential energy. Through its own elastic restoring force, the spring two can play a dual role of resetting and buffering the moving column, helping the moving column to return to the initial position and maintaining the normal placement state of the steel grating. On the other hand, it further absorbs and disperses energy during the impact force transmission process, reduces the damage to the steel grating, prolongs the service life of the steel grating, and ensures its long-term stable use.

Here, the number of the moving column, the fixed cylinder, the spring two, the magnet one and the magnet two is eight groups, and they are arrayed at the bottom end of the frame and the top end of the buffer base. This arrayed distribution mode makes the steel grating uniformly buffered and supported at each part when subjected to external force. No matter the impact force comes from which direction, it can be effectively dispersed and buffered through the coordinated action of the moving column, the spring two and the magnet of multiple parts, avoiding the situation that the steel grating is damaged due to excessive local stress, and ensuring the stability and integrity of the overall structure of the steel grating.
