The present invention relates to a sewage odor control device that can be used easily and used for a lid part of a pipe attachment.

The present applicant is concerned with this type of sewage odor prevention apparatus. Japanese Utility Model Publication No. 61-23105 (Reference 1), Japanese Utility Model Publication No. 61-41823 (Reference 2), Japanese Patent Application Laid-Open No. 11-13121 (Reference 3). And JP-A-11-50519 (Reference 4).
That is, in the sewage odor prevention apparatus already proposed in the literature 1, "in the sewer cover having a water collection hole, the upper part is opened on the lower surface of the sewer cover corresponding to the water collection hole, and the bottom part is flowing water. A bottomed box-shaped water collection receiving box having a side opening on the side face of the inclined surface and a valve seat formed on an end surface of the side opening. At the side opening of the water collection box is attached an elastic valve element that always closes the valve seat by its own weight and opens by the water pressure of the flowing water flowing into the water collection box ” Is taken. As a result, the odor generated in the sewage main pipe is prevented from escaping to the outside by the present apparatus, and the elastic valve body is opened against rainwater to smoothly perform the drainage function.
However, in these sewer odor control devices, there is no space between the water collection box and the attached equipment, depending on the situation of the rainwater drainage and other pipe fittings and the lid. A difficult situation occurs. In other words, in this case, an unreasonable pushing installation operation causes a trouble such as breakage of the odor prevention device, particularly a water collection box.
Furthermore, these odor control devices open and close the side opening (drainage port) of the water collection box (collection cylinder) with a rubber elastic valve body, and have been in the sewer atmosphere for many years. The deterioration gradually progresses, and the elastic valve body is replaced for further reuse of the water collection receiving box body.
The replacement of the elastic valve body is performed in a state where the valve body is fixedly fitted with a fitting (References 1 and 2) or a fixing pin (References 3 and 4), and the valve body is removed and eventually attached. However, it requires work and is difficult. The strong fixation of the valve body also slows the opening / closing operation of the valve body, has poor operability, and is expected to be improved.

The drainage plate is fixed to the lower surface of the flange plate 3 so as to surround the second opening I, the drainage port J is formed on the side, and the mounting type on-off valve 4 is disposed in front of the drainage port J. A box portion 5.
The first box body Sa and the second box body Sb are bonded and fixed to the bottom of the first box body Sa, including the flange plate 3 of the second box body Sb. The fixing tape 7 is omitted in FIG. 1 and shown in FIGS.

Hereinafter, the detail of the member which comprises 1st box part Sa and 2nd box part Sb is demonstrated.
First box body Sa (see FIGS. 1 to 3)
The first box body portion Sa includes a top plate portion 1 and a water collection box portion 2 that is integrally fixed to a lower portion of the top plate portion 1.

Top plate part 1 (see FIGS. 1 to 3)
The top plate portion 1 forms a flat plate, and has a rectangular opening (water collecting port) 1a at the center and is bent when viewed from the side. That is, the front part is raised through the plurality of bent parts (a, b, c, d) from the front part to the rear part of the top plate part 1, the center is low, and the rear part is made slightly high. This corresponds to the shape of the upper edge of the body of rainwater.
In the present embodiment, the top plate 1 is bent, but it may be flat.

Catchment box part 2 (see FIGS. 1 to 3)
The water collection box portion 2 has a side space and a bottom surface, forms a box space that opens up and down, and is fixed to the lower portion of the top plate portion 1. The upward opening of the water collection box portion 2 matches the opening 1 a of the top plate portion 1, and the upper end surface of the side surface portion is fixed to the lower surface of the ceiling portion 1.
The side surface portion of the water collecting box portion 2 includes a side plate 10, a front plate 11, and a rear plate 12, and an upper edge thereof is bent to correspond to the bending of the top plate portion 1. The face plate 12 is inclined.

The front-rear length C of the flange plate 3 is shorter than the front-rear length A of the bottom plate 13 of the water collecting box 2 and longer than the front-rear length B of the first opening H (A>C> B ). The difference between the length A and the length C gives the “movement allowance” of the bottom plate 13, but also relates to the length B. Further, the width (left and right lengths) is substantially equal to the width of the bottom plate 13.
(Second opening I)
The second opening I is formed in a square shape at the center of the flange plate 3. As described above, the opening area of the second opening I is smaller than that of the first opening H, and the longitudinal length D thereof is smaller than the length B of the first opening H. The maximum width of the opening I is determined by securing a predetermined extra length width from the width of the flange plate 3. That is, the extra width provides the stiffness of the flange plate 3 and thus the drainage box 5 and ensures the placement of the opening H on the shelf. Therefore, the maximum width of the opening I is smaller than the width of the first opening H.

Drainage box part 5 (see FIGS. 1 to 5)
The drainage box part 5 has a side part and a bottom face, opens upward, forms a box space in which a drainage port J is formed on the side, and is fixed to the lower part of the flange plate 3. The upward opening of the drainage box portion 5 matches the second opening I of the flange plate 3.

Thus, the belt plate 20 is fixed to the upper portion of the front plate 16 with a fixture 23, and the on-off valve body 22 is pivotally attached to the first bracket 21 of the belt plate 20 to open and close the opening J of the front plate 16.
A metal or a hard synthetic resin is used as a material for the mounting type on-off valve 4 because of non-deformability / hardness requirements, but stainless steel is recommended from the viewpoint of rust prevention.

Specifically, the belt plate 20 is made of a hard belt, and has a first bracket 21 that is bent at right angles at both ends and protrudes to the front surface. The band plate 20 has an attachment hole 20a having the same phase corresponding to the attachment hole 16a (only the reference numeral) provided in the upper part of the front plate 16. At the fixed mounting position, the mounting hole 16a and the mounting hole 20a coincide with each other, and the fixture 23 is mounted over both holes. A pin hole is formed in the first bracket 21.
The on-off valve body 22 includes a flat plate valve portion 25 that covers the valve seat 18 and has a substantially flat plate shape, and a second bracket 26 that extends upward at the upper end of the flat plate valve portion 25. The flat valve portion 25 is mainly a rectangular flat plate portion having a predetermined length and width that sufficiently covers the valve seat 18, and in this embodiment, has a bent portion on both side edges and a bent portion on the lower edge.
The second bracket 26 is connected to the upper end of the flat plate portion 25 and is fixed integrally. The interval between the second brackets 26 is slightly smaller than the first brackets 21 on both sides of the band plate 20. The second bracket 26 has pin holes corresponding to the first bracket 21, and pins 27 are pivotally attached to these pin holes.

With this configuration, the attachment type on-off valve 4 is configured such that the band plate 20 and the on-off valve body 22 are integrated, and the on-off valve body 22 opens and closes around a pin 27 as a rotation center.
Further, the mounting type on-off valve 4 is pivotally attached via the brackets 21 and 26, and the center of rotation of the on-off valve body 22 protrudes forward and is eccentric, so that the opening operation of the on-off valve body 22 becomes rapid.

Fixing device 23 (see FIGS. 2 and 6)
The fixture 23 attaches the attachment type on-off valve 4 to a predetermined position of the front plate 16 of the drainage box portion 5. In this embodiment, a bolt and nut form is adopted, and the attachment type on-off valve 4 can be attached to and detached from the front plate 16.
That is, the mounting hole 16a of the front plate 16 and the mounting hole 20a of the main mounting type on-off valve 4 are made to coincide with each other, bolts are attached to these holes, and nuts are tightened to mount the mounting type on-off valve 4. Bolts are mounted from the back surface of the front plate 16, and the screw portion is protruded from the front surface, a washer is appropriately inserted, a nut is screwed and tightened.
The attachment type on-off valve 4 adopts a predetermined arrangement relationship by the attachment with the fixture 23. That is, the flat plate portion of the mounting type on-off valve 4 is in contact with the valve seat 18 evenly to maintain the sealing property. Further, the side bent portion and the lower bent portion wrap around the side portion and the lower portion of the front plate 16 to improve the sealing performance.

The fixture 23 is not limited to bolts and nuts, and does not exclude other fixing means.
That is, it is a preferable example to use a rivet, in particular, a blind rivet (established in JIS B 01471 (2004)). The blind rivet is made together with the use of a rivet driving tool (riveter). According to the use of this riveter, the mounting type on-off valve 4 can be quickly fixed.

Fixing tape 7 (See Fig. 8)
The fixing tape 7 has an adhesive surface on the lower surface, and forms a thin strip having a predetermined width and length (unit length L). The width of the fixing tape 7 is equal to the width of the bottom plate 13 of the water collection box portion 2. Moreover, it has some flexibility. In this embodiment, the fixed tape 7 is a unit of fixed tape 7A obtained by cutting a long strip-like body into a predetermined length L. An opening 7a corresponding to the opening I of the flange plate 3 is formed in the long fixing tape 7 at an appropriate interval in advance. The opening 7a is drilled later each time, that is, at the site as will be described later. May be.
More specifically, the fixing tape 7 includes an upper layer 30 made of a thin metal (metal foil) or synthetic resin having a cross-sectional structure and an adhesive layer 31 as a lower layer. In addition, an opening 7a is formed inside the belt-like body. Aluminum (0.1 mm) is preferably used as the metal foil. Accordingly, the lower adhesive layer 31 is fixed on the bottom plate 13 of the first box body Sa including the flange 3 of the second box body Sb, and the upper layer plate 30 keeps the water tight. The opening 7a corresponds to the opening I of the flange 3, and the waste water collected in the water collecting box portion 2 passes through the opening 7a. The unit fixing tape 7A is formed in a long strip 7 and is cut in parallel with a cutting portion 7b by appropriately adjusting the length of the front and rear through the opening 7a.

Relationship between the box body parts Sa and Sb (see FIG. 9)
In the present embodiment, the position adjustment between the first box body part Sa and the second box body part Sb is achieved.
FIG. 9 shows one aspect of this positional relationship. In the figure, the thickness of the member cross section is exaggerated and enlarged.
That is, the second box body portion Sb is fitted through the opening H of the bottom plate 13 of the water collecting box portion 2 of the first box body portion Sa, and is supported on the bottom plate 13 via the flange plate 3. Since the longitudinal length (B) of the opening H of the bottom plate 13 is longer than the longitudinal length of the drainage box portion 5 of the second box portion Sb, in other words, the longitudinal length (D) of the opening I, the second box portion Sb can move back and forth with the flange plate 3. Further, since the flange plate 3 has a “movement allowance” in its forward / backward movement, no gap is generated with respect to the opening H of the bottom plate 13 at any position displacement of the second box body portion Sb.
