Title
(EN) Manhole cover for preventing inflow of bad smell and harmful insect
(ZH) 用于防止不良气味和有害昆虫进入的人孔封盖
Abstract
(EN) A manhole cover for preventing the inflow of a bad smell and a harmful insect is provided. More particularly, the manhole cover includes a manhole top plate that has a plurality of drainage holes and a display part; a drainage guide plate that is integrally formed in a bottom part of the manhole top plate; a gate that is provided in a front end exit of the drainage guide plate and that is closed by a weight; and walls that are vertically and integrally formed in four edges of the manhole top plate. The display part, which is provided in one side of the manhole top plate can perform a specific display such as a trademark, a firm name, a logo, a slogan. The gate can be fully opened or closed within a space part by forming the space part in a lower part of the display part. The drainage guide plate is formed in a circular shape or an inclined surface to smoothly perform drainage of water and a front end thereof has an inclined surface so that the gate is safely closed by a weight so as to prevent the inflow of a bad smell and a harmful insect. Specifically, as the manhole cover is made of synthetic resin having excellent mechanical strength, manufacturing thereof is conveniently performed, but a wall of a side in which the display part is positioned is separately formed and then the walls are formed in one body by a fastening member such as a screw or with a method such as welding of synthetic resin so that a core of a mold is easily escaped in a forming process. Furthermore, the manhole cover may be made of synthetic resin such as engineering plastic and ductile cast iron (FCD) , cast iron (FC), etc. It is preferable that the gate is made of aluminum, a stainless steel plate, a galvanized steel sheet, synthetic resin, or so on having corrosion resistance.

本发明提供了一种用于防止不良气味和有害昆虫进入的人孔封盖。更具体而言,人孔封盖包括:具有多个排水孔和显示部分的人孔顶板;整体形成于人孔顶板的底部的排水引导板;设置在排水引导板的前端出口并通过重量来关闭的门;以及垂直且整体形成于人孔顶板的四个边缘的壁。设置在人孔顶板的一侧中的显示部分可以显示诸如商标、公司名称、标识、标语等具体的显示标识。通过在显示部分的下部形成空间部分,可以在空间部分中完全打开或关闭门。排水引导板形成为圆形形状或者倾斜表面,以平稳地排放水,并且其前端具有倾斜表面,使得门通过重量安全地关闭,以防止不良气味和有害昆虫进入。具体而言,因为人孔封盖由具有良好机械强度的合成树脂制成,所以可以方便地进行制造,但是定位显示部分一侧的壁单独形成,然后通过诸如螺钉之类的紧固构件或者用诸如合成树脂焊接之类的方法使壁形成为一整体,以便在成型过程中方便分离模具的芯。此外,人孔封盖可以由诸如工程塑料之类的合成树脂、球墨铸铁(FCD)、铸铁(FC)等制成。优选地,门由铝、不锈钢板、镀锌钢板、合成树脂等具有抗腐蚀性的材料制成。在具有上述构造的人孔封盖中,由于人孔顶板和排水引导板整体形成,所以可以方便地构造它们。因为门能够一直稳定地关闭,所以可以防止不良气味和有害昆虫的进入。由于排水引导板很大并且是倾斜的,所以可以非常平稳地进行排水并且在使用时不用担心被损坏或者发生故障。此外,因为人孔封盖由合成树脂制成,所以其非常轻,很容易握持。人孔封盖可以做成各种颜色,并且可以在其显示部分显示各种标语、公司名称、商标等,因而能够进一步提高市民的意识并改善市容。
