Description

Technical Field

[0001] The utility model relates to the technical field of drainage manhole covers, in particular to a drainage cast iron manhole cover with an anti-blocking structure. Background Art

[0002] A drainage manhole cover refers to a manhole cover installed in the drainage system pipe for drainage. It is an important component of the drainage system. It is generally made of cast iron and has the characteristics of good toughness, high strength and corrosion resistance. It is widely used.

[0003] The existing cast iron manhole covers with drainage have the following disadvantages during use: the surface of the cast iron manhole cover is provided with drainage holes for convenient drainage. In order to isolate impurities, a filter is generally installed at the drainage hole for filtering. During actual use, since the filter area is very small, if the impurities cover the surface of the filter, it is easy to cause the drainage manhole cover to be blocked, affecting the drainage efficiency and patency. For this reason, we propose a drainage cast iron manhole cover with an anti-blocking structure. Utility Model Content

[0004] The main purpose of the utility model is to provide a cast iron manhole cover with an anti-blocking structure. By installing a storage mechanism inside the cover body, impurities are collected in a concentrated manner using a sinking type storage method, thereby reducing blockages, improving drainage efficiency, and effectively solving the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A cast iron drainage manhole cover with an anti-blocking structure comprises a cover body and a storage mechanism, wherein the storage mechanism is installed inside the cover body, and the storage mechanism comprises a connecting ring, a water discharge cover, an annular cylinder, a spring and an annular filter cover, the cover body is detachably connected to the connecting ring and the connecting ring is overlapped with the water discharge cover, an annular cylinder is welded to the bottom of the connecting ring, a spring is installed vertically inside the annular cylinder and the annular filter cover is movably connected to the annular cylinder through the spring.

[0007] Furthermore, it also includes a docking mechanism, a docking mechanism is arranged between the connecting ring and the cover body, the docking mechanism includes an outer screw groove and an inner screw groove, the outer circumference of the connecting ring is opened, and the inner wall of the cover body is opened with an inner screw groove matching the outer screw groove; the cover body is opened with an inner screw groove, and when installing the connecting ring, the outer screw groove on its outer circumference is aligned with the inner screw groove and screwed in, so as to realize the installation of the connecting ring. When it is necessary to clean impurities, the connecting ring can be rotated to lift it out as a whole, and the annular filter cover can be lifted up to facilitate cleaning of the collected impurities.

[0008] Furthermore, an annular insertion cavity is opened inside the annular cylinder and a spring is installed inside the annular insertion cavity, and the end of the annular filter cover is inserted into the annular insertion cavity; the annular insertion cavity plays a role of installation and limiting, so that the annular filter cover can only move in the vertical direction.

[0009] Furthermore, a drainage hole is provided on the top of the annular cylinder for convenient drainage of water; when too many impurities are collected inside the annular filter cover, the excess water can be discharged from the drainage hole.

[0010] Furthermore, handles are welded on both ends of the surface of the connecting ring and the handles are located inside the connecting ring; the handle structure facilitates twisting the connecting ring and lifting the connecting ring as a whole.

[0011] Compared with the prior art, the utility model has the following beneficial effects: a connecting ring is installed inside the cover body, and the drain cover is directly overlapped on the top of the connecting ring for drainage. During the draining process, water mixed with impurities passes through the drain cover and falls into the annular filter cover at the bottom of the annular cylinder, where the impurities are isolated and collected, and the water is discharged normally. As the impurities inside the annular filter cover continue to increase, the annular filter cover is pressed down under the action of gravity, thereby increasing its internal storage space to store more impurities. Compared with the existing ordinary filter mechanism, the problem of rapid clogging of the drainage manhole cover is avoided, and daily drainage needs can be met. At the same time, impurities are collected in a centralized manner for easy cleaning. An inner screw groove is provided on the inner periphery of the cover body. When installing the connecting ring, the outer screw groove on its outer periphery is aligned with the inner screw groove and screwed in, thereby realizing the installation of the connecting ring. When it is necessary to clean impurities, the connecting ring can be rotated to lift it out as a whole, and the annular filter cover can be lifted up to facilitate cleaning of the collected impurities.
