The odor inside the drain 4 is blocked.

In this state, when rainwater flows through the upper grating 600 at the time of living sewage or rain, the introduced rainwater falls to the prefabricated switchgear 300 and follows the inclined portion 3 of the unit blocks 8 and 8 '. When the water pressure or the moving pressure and the weight of the water generated by the water flowing down and flowing to the opening and closing plate 5 are transferred to the opening and closing plate 5, the base portion of the opening and closing plate 5 placed in the seat part 6 is shown in FIG. 5. (13) The plate body 14 is rotated about both shafts 12, and the inlet water flows down into the sewer through the drain port 4, and the opening and closing plate 5 is provided with water until the inflow of water is completed. It is kept open by.

Subsequently, when the inflow of the rainwater ends and the water pressure of the water flowing down through the inclined portion 3 is lost, the opening and closing plate 5 is rotated by the rotation by the self-weight and the center of gravity to return to the initial state, and the odor blocking plate 15 As in the inclined state, the odor blocking plate 15 and the inclined state in close contact with the horizontal contact portion 17 of the inclined portion 3 is located in the airtight state and closes the drain port 4 and the odor of the drain port 4 leaks out. Will be blocked.

The opening and closing plate 5 which is installed to be inclined by the malodor blocking plate 15 is inertial to rotate in the center movement, so that the malodor blocking plate 15 and the lower horizontal contact portion 17 of the inclined portion 3 are strongly inclined. Because it is close to ensure the confidentiality of the drain (4).

In addition, leakage of airtightness through the base 13 of the opening and closing plate 5 around the inside of the seat portion 6 where the base portion 13 of the opening and closing plate 5 abuts and the inside of the upper surface of the inclined portion 3 is prevented. Since the curved close contact portion 16 corresponding to the shape of the base portion 13 to be blocked is formed, the inner portion of the seat portion 6 and the inclined portion ( 3) is in close contact with the curved contact portion 16 formed inside the upper surface of the upper surface, and as described above, the bottom of the opening and closing plate 5 is in contact with the horizontal contact portion 17 formed at the lower end of the inclined portion 3 Since the drain 4 is completely closed, when the rainwater does not flow, it can reliably block the odor flowing back from the drain 4.

The prefabricated opening and closing device 300 of the present invention is remarkably improved compared to the conventional prior application, and the conventional opening and closing device is not easy to manufacture because the whole is configured as a single body, and in particular, the hinge of the opening and closing door is installed on the fixing pin. Since the foreign matter easily enters the inside, there is a problem in that the rotation operation is not smooth, causing problems in drainage and the odor blocking effect is reduced, but the prefabricated switchgear 300 according to the present invention is injection-molded unit block 8 as a synthetic resin material. (8 ') is made by simply connecting up, down, left, and right in a prefabricated manner, and the opening and closing plate (5) is enclosed in the seat part (6), so it is very easy to manufacture, and the opening and closing plate (5) is formed of a synthetic resin that is light and rust free Since both side shafts 12 of the base portion 13 are mounted on the seat portion 6 and can rotate freely, the problem that the rotation operation is inhibited by foreign matters Not only does it occur at all, but the curved contact portion 16 is formed in the periphery of the base portion 13 of the opening / closing plate 5 and the seat portion 6, so that the airtightness is more reliably maintained. The effect of preventing backflow of rainwater is very good.
