JP3000935U - Sewage pipe cleaning port closing device - Google Patents

Abstract

(57) [Summary] (Correction) [Purpose] To provide a device with a good appearance that does not allow foreign matter to flow in during floor cleaning and does not scatter offensive odors under normal conditions. [Structure] A receiving portion piece 5 is projectingly provided on an inner peripheral surface of a cylindrical body 1 that constitutes a cleaning port 8, and the receiving portion piece 5 and a sealing lid 16 that is detachably screwed to the cylindrical body 1 form a porous body. The ring-shaped main body 10 of the plate 9 is held.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a closing device for a sewer cleaning opening.

[0002]

[Prior art]

 A sealing lid is screwed onto the cylinder that constitutes the cleaning port, and during cleaning work the sealing cover is removed and the cleaning port is used as an insertion port for a cleaning tool into the sewer pipe.

[0003]

[Problems to be solved by the device]

 In the conventional example, when cleaning the area around the cleaning port after cleaning the sewer pipe, there is a risk that foreign matter may be accidentally poured into the cleaning port, which serves as a drainage port for waste water.

The present invention has been made by paying attention to the drawbacks of the conventional example.

[0005]

[Means for Solving the Problems]

 A receiving portion piece is provided on the inner peripheral surface of the cylindrical body forming the cleaning port, and the ring-shaped main body of the perforated plate is held by the receiving portion piece and the sealing lid detachably screwed to the cylindrical body. In this configuration, the tubular body that constitutes the drainage port is configured by a cleaning port configuration tube including a tubular portion and a flange portion provided at the upper end of the tubular portion, and the flange portion is provided on the floor surface. It is placed on the drainage pipe buried in to improve the appearance of the cleaning port, and the perforated plate is made of elastic material to prevent odor.

【Example】

 1 is a vertical sectional view and FIG. 2 is a perspective view of a perforated plate.

In the figure, reference numeral 1 is a cleaning port forming tube, and the cleaning port forming tube 1 is composed of a tubular portion 2 and a flange portion 3 provided at an upper end of the tubular portion 2, and an inner peripheral surface of the tubular portion 2 is formed. The first receiving part piece 4 is provided near the upper end of the first receiving part piece 4, and the second receiving part piece 5 is provided below the first receiving part piece 4 so as to project from the first receiving part piece 4. A female screw 6 is provided on the inner peripheral surface of the receiving portion piece 4.

In this cleaning port forming cylinder 1, a cylindrical portion 2 is inserted into a drainage pipe 7 buried in a floor surface, and a flange portion 3 is placed on the drainage pipe 7 to form a cleaning aperture 8.

In the figure, reference numeral 9 denotes a perforated plate, which is made of elastic rubber, and is constituted by connecting a hole forming part 11 to a ring-shaped main body 10 and providing a communication hole 12 of an appropriate size. The perforated plate 9 is received by the second receiving portion piece 5 and is attached to the cleaning port forming cylinder 1.

Further, 16 is a hermetically-sealing lid, and the hermetically-sealing lid 16 is configured by providing a male screw cylinder 15 on the lower surface of a main plate 14 having a pair of locking grooves 13, 13 for locking the opening / closing tool on the upper surface. The male screw cylinder 15 is screwed into the female screw 6 of the cleaning port constituting cylinder 1, and the ring-shaped main body 10 of the perforated plate 9 is held by the second receiving part 5 to prevent odor. The cleaning port in a normal state is for preventing dust and other foreign matter from entering the inside of the cylinder 1 constituting the cleaning port.

Therefore, after cleaning the sewer pipe or when cleaning the floor surface from the beginning, the perforated plate is left attached, and the perforated plate is removed as necessary.

The perforated plate may be made of an elastic resin (for example, polyethylene), and the shape or arrangement of the communication holes need not be limited to the structure of the embodiment.

[0013]

[Effect of device]

 Since the present invention is configured as described above, it is possible to provide a device having a good external appearance without pouring foreign matter when cleaning a floor surface, and in the normal state in which a bad odor does not scatter.
