Description

Technical Field

[0001] This utility model relates to the field of sewage pipes, and in particular to an observation port for sewage pipes. Background Technology

[0002] A sewage pipe is a pipe used to discharge sewage. In order to better observe the sewage discharge, an observation port is usually set at a certain position of the sewage pipe, and the internal condition of the sewage pipe can be easily observed through a transparent material.

[0003] Chinese Patent Publication No. CN207878611U discloses an observation port for a water supply and drainage sewage pipe, including a sewage pipe and an observation port. The observation port is fixed to the sewage pipe, and a pipe cover is installed on the observation port via a threaded connection. A connecting plate is horizontally fixed on each opposite side of the observation port, and each connecting plate has a through hole. A clamping plate is horizontally arranged on the upper surface of the pipe cover, and a threaded rod is vertically fixed at each end of the clamping plate. The threaded rods on both sides are movably inserted into the through holes on both sides, with the lower end of the threaded rods passing through the through holes and extending below the clamping plate. A fastening nut is installed on each threaded rod, and the fastening nut is located below the connecting plate. This utility model has advantages such as good robustness and long service life.

[0004] The existing sewage pipe observation port has a transparent observation plate or cover that is inconvenient to disassemble and replace. Since the sewage inside the sewage pipe is corrosive, the transparent observation plate or cover is a consumable part that needs to be replaced or cleaned regularly. The existing device is difficult to disassemble and install, which is not conducive to later maintenance. Moreover, when the sewage pipe is discharging, the sewage will stick to the observation port, which will affect the line of sight and make it impossible to observe the inside of the sewage pipe. Utility Model Content

[0005] The main purpose of this utility model is to provide an observation port for sewage pipes, which can effectively solve the technical problems in the background art of inconvenience in later maintenance and inability to clean the dirt adhering to the observation port during use.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An observation port for a sewage pipe includes a connecting pipe with connecting flanges fixedly installed at both ends. An observation pipe is fixedly installed at the outer center of the connecting pipe, and a fixed flange is fixedly installed at the top of the observation pipe. An installation flange is bolted to the upper part of the fixed flange. An observation structure is provided between the fixed flange and the installation flange. The observation structure includes a spherical cover with a stepped plate fixedly installed at the bottom of the spherical cover. A groove is formed on the upper surface of the fixed flange, and a groove is also formed on the lower surface of the installation flange. The depth of one groove is half the thickness of the stepped plate, and the stepped plate is located in two grooves.

[0008] As a further embodiment of this utility model, the interior of the spherical cover is provided with a cleaning structure, which includes a first magnetic block, a second magnetic block and a sliding groove. The sliding groove is opened on the inner side of the stepped plate. Two scrapers are symmetrically installed on the outside of the second magnetic block, and a slider is fixedly installed at one end of the scraper. The slider is slidably connected to the sliding groove.

[0009] As a further embodiment of this utility model, the outer wall of the scraper is attached to the inner wall of the spherical cover, and the first magnetic block and the second magnetic block are magnetically connected.

[0010] As a further embodiment of this utility model, the bottom of the first magnetic block is attached to the outer wall of the spherical cover, and the upper part of the second magnetic block is attached to the inner wall of the spherical cover.

[0011] As a further embodiment of this utility model, rubber gaskets are glued to both the upper part of the groove of the fixed flange and the bottom of the groove of the mounting flange.

[0012] As a further embodiment of this invention, the spherical cover is made transparent.

[0013] The beneficial effects of this utility model are as follows:

[0014] By setting the mounting flange to fit the groove, the spherical cover can be easily removed and installed, which makes it easier to clean and replace the spherical cover later, and makes maintenance more convenient.

[0015] By setting up a scraper in conjunction with a first magnetic block and a second magnetic block, the first magnetic block can drive the second magnetic block to rotate from the outside, thereby driving the scraper to rotate. The scraper can also be magnetically connected to the first magnetic block. The scraper can be rotated by being attracted by the external magnetic block, thus cleaning the inner wall of the spherical cover and preventing dirt from obstructing the view.
