Description

  The present invention relates to a deodorizer for rainwater mass and a rainwater mass with deodorizer.

Rainwater mass is installed in the underground such as both ends of the road. At the bottom of this type of rainwater mass, a mud reservoir with a height of 150 mm or more is required under the sewerage law.
In recent years, paving roads has progressed in urban areas. Therefore, most of what is collected in the mud reservoir of rainwater mass is not dirt but dirt and fallen leaves (hereinafter referred to as "trash and the like"). It will corrode if dirt etc. stay in the mud reservoir with rainwater. As a result, an offensive odor is generated in the rainwater mass.

The rainwater mass described in Patent Document 1 below is known. This rainwater mass is equipped with a medium screen device. The middle screen device includes a shielding member capable of swinging up and down.
According to the rainwater mass, the weight of the rainwater swings the shielding member open when it rains. When the rainwater stops flowing, the shielding member swings in the opposite direction using its own weight and closes (gravity opening and closing type). In this way, it is possible to suppress the intrusion of dust and the like into the rainwater mass.

JP 2004-285663 A

  In the above-mentioned conventional rainwater mass, when the shielding member is opened and then closed, if the dust and the like bites between the shielding member and the side surface of the rainwater mass, the lid will not be completely closed. As a result, the deodorizing effect may be lost.

  This invention is made in view of the situation mentioned above, Comprising: It aims at providing the deodorizer for rain water mass which can exhibit the deodorizing effect reliably.

In order to solve the above-mentioned subject, the present invention proposes the following means.
According to the present invention, there is provided a rainwater deodorizer for rainwater mass comprising: a mass main body portion; a mud reservoir provided at a lower end of the mass main body portion; and an outlet provided at a side surface of the mass main body portion A lid fitted to the rainwater mass to cover the mud reservoir, the height position of the upper surface of the lid being less than the height of the outlet of the outlet .

A lid is fitted in the rainwater mass. Therefore, the lid can be firmly fixed to the rainwater mass by using the fitting force generated between the lid and the rainwater mass. Thereby, for example, it is suppressed that dust etc. enter between the outer peripheral surface of the lid and the side surface of the rainwater mass.
The height position of the upper surface of the lid is less than the top height of the outlet. Therefore, the refuse etc. which invaded in the inside of a rainwater mass from the exterior can be discharged | emitted from the mass main-body part through the outflow port outside.
As mentioned above, it becomes possible to suppress that refuse etc. retain in rain water mass, and it can be made to certainly show the deodorizing effect by a deodorizing tool.

  The height position of the upper surface of the lid may be equal to or higher than the bottom height of the outlet.

  The height position of the upper surface of the lid is equal to or higher than the bottom height of the outlet. Therefore, when the dust and the like on the upper surface of the lid flow out from the mass main body to the outflow port, the dust and the like can flow out to the outflow port without being caught on the side surface of the mass main body. As a result, dust and the like can be reliably discharged to the outlet without staying in the mass main body.

  The lid may close the mud reservoir.

Water is stored in the mud reservoir. If mosquitoes etc. lay eggs and reproduce in this water, for example, the cleaning work of the rainwater mass will be affected. Cleaning of the rainwater mass is performed, for example, by a vendor on a city road where traffic is heavy, and in most other places, it is performed by a cleaning volunteer of each residents' association. Anti-mosquito measures are desired in consideration of cleaning work.
The lid blocks the mud reservoir. Therefore, the lid covers the water surface of the mud reservoir, and it is possible to prevent mosquitoes and the like from laying eggs in the water in the mud reservoir. Even if mosquitoes and the like breed in the water in the mud reservoir, the lid portion can restrict movement of the mosquitoes and the like from the mud reservoir to the outside. Therefore, the deodorant can reliably exhibit not only the deodorizing effect but also the mosquito preventing effect. As a result, the cleaning work of the rainwater mass can be realized efficiently.

  The lid may be deformable or demountable.

  The lid is deformable or demountable. Therefore, for example, when the lid is attached to the rainwater mass, the shape of the lid can be changed relative to the shape in which the lid is fitted in the rainwater mass. Thereby, for example, even when the opening at the upper end of the rainwater mass is narrow, the lid portion can be made to easily pass the opening. Therefore, the workability at the time of attaching and detaching a cover part to a rainwater mass can be improved. As a result, the cleaning work of the rainwater mass can be realized efficiently.

  The rainwater mass with deodorant according to the present invention comprises a mass main body, a mud reservoir provided at the lower end of the mass main body, and an outlet provided at the side surface of the mass main body. And the deodorizer.

The deodorant equipped rainwater mass is buried underground, for example, at both ends of the road. The deodorant equipped rainwater mass includes not only so-called rainwater mass but also so-called rainwater permeation mass.

  As shown in FIGS. 1 and 2, the deodorant equipped rainwater mass 10 is provided with a rainwater mass 11 and a deodorant 12. The rainwater mass 11 includes a mass main body 21, a mud reservoir 22, a riser pipe 23, an inflow port 24 (inflow pipe), and an outflow port 25 (outflow pipe). The mass main body portion 21, the rising pipe 23, the inlet 24 and the outlet 25 are integrally formed of the same material (for example, polyvinyl chloride or polypropylene). The mass body 21, the riser 23, the inlet 24 and the outlet 25 form one molded article 26. The mud reservoir 22 is attached to the molded product 26.

  The mass main body portion 21, the mud reservoir portion 22 and the riser pipe 23 are all formed in a cylindrical shape. The central axes of the mass main body portion 21, the mud storage portion 22 and the riser pipe 23 are located on a common axis. Hereinafter, the common axis is referred to as a mass axis O. The mass axis O direction is referred to as the vertical direction Z. The mud reservoir 22 and the riser 23 sandwich the mass body 21 in the vertical direction Z. The mud reservoir 22 side with respect to the mass main body 21 is referred to as the lower side along the vertical direction Z, and the riser 23 side is referred to as the upper side. The direction orthogonal to the mass axis O is referred to as the radial direction. The direction of rotation around the mass axis O is referred to as the circumferential direction.

  The riser 23 is provided at the upper end of the mass main body 21. Rainwater from the ground surface flows from the riser 23 into the mass main body 21. The riser 23 is smaller in diameter than the mass main body 21. The riser 23 is connected to the mass main body 21 via a taper 27. The tapered portion 27 connects the upper end of the mass main portion 21 and the lower end of the rising pipe 23. The tapered portion 27 is reduced in diameter toward the upper side.

  The inlet 24 and the outlet 25 are respectively provided on the side surface of the mass main body 21. The inlet 24 and the outlet 25 are formed in a tubular shape projecting radially outward from the mass main body 21. The inlet 24 and the outlet 25 are disposed on the opposite sides of the mass main body 21. The inlet 24 and the outlet 25 are not limited to the tubular shape. For example, the inlet 24 and the outlet 25 may be through holes formed on the side of the mass main body 21. The inlet 24 and the outlet 25 may not be disposed on opposite sides of the mass main body 21. For example, the inflow port 24 and the outflow port 25 may be disposed at positions separated by 90 ° at a central angle centered on the mass axis O.

  In a top view of the rainwater mass 11, central axes of the inlet 24 and the outlet 25 are located on a common axis. The common axis passes through the mass axis O in the top view. Hereinafter, the direction in which the common axis extends in the top view is referred to as a flow direction X. The inlet 24 side along the flow direction X is referred to as the upstream X1. The outlet 25 side along the flow direction X is referred to as the downstream X2. In the top view, a direction orthogonal to the flow direction X is referred to as an orthogonal direction Y.

The first horizontal draw pipe 28 is fitted to the inflow port 24 from the inside. Rainwater flows from the upstream X 1 into the mass main body 21 through the first horizontal pull pipe 28. For example, another rainwater mass is disposed upstream of the rainwater mass 11 X1.
The second horizontal draw pipe 29 is fitted to the outlet 25 from the outside. The rainwater in the mass main body 21 flows out to the downstream X2 through the second horizontal draw pipe 29. For example, a merging mass is disposed downstream of the rainwater mass 11 X2.

  As shown in FIG. 2, the mud reservoir 22 is provided at the lower end of the mass main body 21. The mud reservoir 22 is fitted to the lower end of the mass main body 21. The mud reservoir 22 includes a peripheral wall 30 and a bottom wall 31. The bottom wall portion 31 closes the lower end of the peripheral wall portion 30. The peripheral wall 30 and the bottom wall 31 are formed of separate molded products. The peripheral wall 30 and the bottom wall 31 are fixed, for example, by bonding or the like.

The deodorizing tool 12 is used for the rainwater mass 11. The deodorizing tool 12 is removable from the rainwater mass 11. The deodorizer 12 is provided with a lid 41.
The lid 41 is fitted in the rainwater mass 11 and covers the mud reservoir 22. The lid 41 is fitted in the lower end of the mass main body 21 and closes the mud reservoir 22. The outer peripheral surface of the cover 41 is formed of an elastic body (for example, rubber packing). The lid 41 is tightly fitted in the lower end of the mass main body 21. In the present embodiment, the cover 41 is closely fitted in the mass main body 21 in a state where the outer peripheral surface (elastic body) of the cover 41 is elastically deformed, and the cover 41 is a mud reservoir 22. Is sealed. The lid 41 is configured so that the lid 41 does not come off even if water accumulates in the mud reservoir 22 and a buoyancy occurs in the lid 41.

The lid portion 41 has a diameter larger than that of the riser pipe 23. The central axis of the lid 41 is located on the mass axis O. The lid 41 may be fitted in the upper end of the mud reservoir 22. Also in this case, the lid 41 closes the mud reservoir 22.
As shown in FIGS. 3 to 6, the lid portion 41 is provided with a groove portion 42, an instruction portion 43, a grip portion 44, and a weight portion 45. The groove portion 42, the instruction portion 43 and the grip portion 44 are provided on the upper surface 41 a of the lid portion 41. The weight 45 is provided on the lower surface of the lid 41.

  The groove 42 extends in the flow direction X and crosses the lid 41 in the flow direction X. The groove 42 is disposed at the center of the lid 41 in the orthogonal direction Y. The bottom surface 42 a of the groove 42 is inclined with respect to the horizontal surface in a longitudinal sectional view as viewed in the orthogonal direction Y. The bottom surface 42a of the groove 42 (the upper surface 41a of the lid 41) extends downward from the upstream X1 toward the downstream X2.

In the illustrated example, the portion (hereinafter referred to as "excluded portion") excluding the groove 42 in the upper surface 41a of the lid 41 extends along the horizontal surface and is not inclined with respect to the horizontal surface. As a result, the bottom surface 42 a of the groove 42 is inclined with respect to the excluded portion.
The upper surface 41 a of the lid 41 is formed smooth in the flow direction X over the entire area. Thereby, stagnation of rain water in the flow direction X on the lid 41 is suppressed.

  The provision of the groove 42 in the lid 41 allows rainwater flowing in the flow direction X on the lid 41 to be collected in the groove 42. Furthermore, a slope (flow gradient) from the upstream X1 to the downstream X2 is provided on the bottom surface 42a of the groove 42. From the above, the rainwater collected in the groove 42 smoothly flows from the upstream X1 to the downstream X2.

  The indicator 43 indicates the direction in which the upper surface 41 a of the lid 41 is inclined (the direction of the flow gradient). In the present embodiment, the indicator 43 indicates the direction in which the bottom surface 42 a of the groove 42 is inclined. The indicator 43 is disposed on the bottom surface 42 a of the groove 42. The instruction unit 43 is an arrow extending in the direction in which the inclination is lowered (in the illustrated example, the direction from the upstream X1 to the downstream X2).

  The instruction unit 43 is formed by, for example, painting or the like. The indicator 43 is formed in a form that does not affect the degree of inclination of the bottom surface 42 a of the groove 42 (the upper surface 41 a of the lid 41). The indicating portion 43 is formed substantially flush with the bottom surface 42 a of the groove 42, and no step is formed on the bottom surface 42 a of the groove 42.

  The grip portion 44 protrudes from the lid portion 41 in the vertical direction Z. The worker grips the grip 44 using, for example, a hand or a jig (for example, an L-shaped hook). The grips 44 are arranged in parallel to the groove 42 in the orthogonal direction Y. The grip portion 44 is disposed at an end portion of the lid portion 41 on the upstream side X1.

  The weight 45 increases the specific gravity of the entire lid 41. The weight 45 is adjusted, for example, so that the specific gravity of the entire lid 41 is 1 (specific gravity of water) or more. Thereby, for example, when a large amount of rainfall occurs, and the unexpected external force is applied to the lid 41 from the rainwater, the lid 41 (the deodorizing tool 12) is prevented from going wild in the rainwater mass 11. Can. The weight portions 45 are arranged in a pair at intervals in the flow direction X.

  As a main material of the lid portion 41, a material which is excellent in chemical resistance (including resistance to oil) and which is not easily corroded is desirable. Examples of main materials of the lid 41 include synthetic wood, FRP (glass fiber reinforced plastic), thermosetting resin, thermoplastic resin, and metal. Examples of synthetic wood include glass fiber reinforced urethane resin foam (product name: “Eslon (registered trademark) Neo Lumber FFU”, manufactured by Sekisui Chemical Co., Ltd.). Examples of the thermosetting resin include resin concrete. Thermoplastic resins include polyvinyl chloride, polyethylene and waste plastics. Examples of the metal include stainless steel and iron. The weight 45 is preferably applied when the specific gravity of the lid 41 is smaller than one.

  The lid 41 is deformable or dismountable. In the present embodiment, the lid 41 is deformable. The lid 41 is divided into a first divided body 46 and a second divided body 47. A dividing surface 48 is formed on the lid 41. The dividing surface 48 divides the lid 41 into two parts of a first dividing body 46 and a second dividing body 47. The dividing surface 48 extends in the orthogonal direction Y and passes on the mass axis O (the central axis of the lid 41). The dividing surface 48 divides the lid 41 into two in the flow direction X. In each of the first divided body 46 and the second divided body 47, one weight 45 is disposed.

The first divided body 46 and the second divided body 47 may be formed by, for example, cutting out, pressing, or injection of a molding material into a mold.
In addition, an elastic member (for example, rubber packing) may be disposed on the dividing surface 48. In this case, it is possible to suppress the formation of a gap in the dividing surface 48 (between the first divided body 46 and the second divided body 47).

  The first divided body 46 and the second divided body 47 are connected via a hinge member 49. The hinge member 49 rotatably couples the first divided body 46 and the second divided body 47 around the hinge axis R. The hinge axis R extends along the orthogonal direction Y. The lid 41 is bendable in the flow direction X as a whole. The folded lid portion 41 can enter into the rainwater mass 11 from the rising pipe 23. The size in the flow direction X of the folded lid portion 41 is smaller than the inner diameter of the rising pipe 23. The folded lid 41 can be deployed in the mass main body 21.

The hinge member 49 is disposed on the upper surface 41 a of the lid 41. The hinge members 49 are provided in a pair at regular intervals in the orthogonal direction Y. The pair of hinge members 49 sandwich the groove 42 along the orthogonal direction Y.
The cover 41 is further provided with a restricting portion 50. The restricting unit 50 switches between permitting and restricting relative movement of the first divided body 46 and the second divided body 47. The restricting portion 50 is provided on the lower surface of the lid portion 41. The restricting portion 50 is formed by a so-called snap lock (draw lock).

  As shown in FIG. 2, the height position of the top surface 41 a of the lid 41 (the bottom surface 42 a of the groove 42) is less than the top height (pipe top height) H 1 of the outlet 25. The mouth height H1 of the outlet 25 is the height position of the uppermost portion of the end (open end) connected to the mass main body 21 at the outlet 25 in the vertical direction Z (mud The distance between the bottom wall 31 of the reservoir 22 and the vertical direction Z) is referred to. In the present embodiment, the height position of the portion located at the most downstream X2 in the upper surface 41a of the lid 41 (hereinafter referred to as "the downstream end portion of the lid 41") is the height of the top of the mouth H1 of the outlet 25. Too low. A space located above the upper surface 41 a of the lid 41 in the rainwater mass 11 communicates with the inside of the outlet 25.

  The height position of the upper surface 41 a of the lid 41 is equal to or higher than the bottom height (pipe bottom height) H 2 of the outlet 25. The bottom height H2 of the outlet 25 is the height position of the lowermost portion of the end (open end) connected to the mass main body 21 at the outlet 25 Say. In the present embodiment, the height position of the downstream end portion of the lid 41 is equal to the bottom height H 2 of the outlet 25.

As described above, according to the rain-free mass with odor control device 10 according to the present embodiment, the lid 41 is fitted in the rain-water mass 11. Therefore, the lid 41 can be firmly fixed to the rainwater mass 11 by using the fitting force generated between the lid 41 and the rainwater mass 11. Thereby, it is suppressed that dust etc. enter between the outer peripheral surface of the cover part 41, and the side surface of the rainwater mass 11, for example.
The height position of the upper surface 41 a of the lid 41 is less than the top height H 1 of the outlet 25. Therefore, the waste etc. which invaded in the inside of the rainwater mass 11 from the exterior can be discharged | emitted from the mass main-body part 21 through the outflow port 25 outside.
As mentioned above, it becomes possible to suppress that a refuse etc. retain in rain water mass 11, and it can be made to exhibit the deodorizing effect by deodorizing tool 12 certainly.

  The height position of the upper surface 41 a of the lid 41 is equal to or more than the mouth bottom height H 2 of the outlet 25. Therefore, when the dust and the like on the upper surface 41 a of the lid 41 flow out from the mass main body 21 to the outflow port 25, the dust and the like can be flowed out to the outflow port 25 without being caught on the side surface of the mass main body 21. it can. As a result, dust and the like can be reliably discharged to the outlet 25 without staying in the mass main body 21.

Water is stored in the mud reservoir 22. If a mosquito etc. lay eggs and propagate in this water, for example, the cleaning operation of the rainwater mass 11 will be affected. For example, cleaning of the rainwater mass 11 is performed by a vendor on a city road where traffic is heavy, and in most other places, it is performed by a cleaning volunteer of each residents' association. Anti-mosquito measures are desired in consideration of cleaning work.
A lid 41 closes the mud reservoir 22. Therefore, the lid 41 covers the water surface of the mud reservoir 22, and it is possible to prevent mosquitoes and the like from laying eggs in the water in the mud reservoir 22. Even if mosquitoes and the like breed in the water in the mud reservoir 22, the lid 41 can restrict movement of the mosquitoes and the like from the mud reservoir 22 to the outside. Therefore, the deodorizing tool 12 can reliably exhibit not only the deodorizing effect but also the mosquito preventing effect. As a result, the cleaning work of the rainwater mass 11 can be realized efficiently.

  The lid 41 is deformable or demountable. Therefore, for example, when the lid 41 is attached to the rainwater mass 11, the shape of the lid 41 can be changed relative to the shape in which the lid 41 is fitted in the rainwater mass 11. Thereby, for example, even when the opening (in the rising pipe 23) at the upper end of the rainwater mass 11 is narrow, the opening can be easily passed through the lid 41. Therefore, the workability at the time of attaching and detaching the cover part 41 to the rainwater mass 11 can be improved. As a result, the cleaning work of the rainwater mass 11 can be realized efficiently.

  In addition, although the groove part 42 is arrange | positioned in the center part of the orthogonal direction Y in the cover part 41 in this embodiment, this invention is not limited to this. For example, as shown in FIG. 7, the groove 42 may be formed over the entire top surface 41 a of the lid 41. In a front view of the groove portion 42 when the groove portion 42 is viewed in the flow direction X, the groove portion 42 is formed in a V shape which protrudes downward.

Second Embodiment
Next, a second embodiment of the present invention will be described with reference to FIG. 8 and FIG.

The lid 41 is fitted to the mud reservoir 22 via the support 61. The groove 42 is not provided on the upper surface 41 a of the lid 41. The upper surface 41a of the lid 41 extends downward from the upstream X1 to the downstream X2 throughout the entire region, and has a flow gradient.

  The support portion 61 is equally divided into two in the orthogonal direction Y. The divided support portion 61 has a semi-cylindrical shape. Therefore, when making the support part 61 stand up and approach into the rainwater mass 11 from the pipe | tube 23, the support part 61 can be elastically deformed so that the both ends of the circumferential direction of the divided support part 61 may be approached. Thereby, the magnitude | size of the flow direction X of the divided support part 61 can be made smaller than the internal diameter of the standup pipe 23. As shown in FIG. As a result, the support portion 61 can easily enter the rainwater mass 11. However, the support portion 61 may be indivisible. For example, the support portion 61 may be formed in a cylindrical shape having an outer diameter equal to or less than the inner diameter of the rising pipe 23 so that the support portion 61 can rise and enter into the pipe 23 without disassembling the support portion 61. Furthermore, for example, a packing made of an elastic body may be provided on the outer periphery of the support portion 61. The packing may facilitate the insertion of the support portion 61 into the mud reservoir 22 and configure the support portion 61 so as to obtain a frictional force for connecting the support portion 61 and the mud reservoir 22. .

  The technical scope of the present invention is not limited to the above embodiment, and various modifications can be made without departing from the scope of the present invention.

  Instead of the snap lock, for example, a splint can be adopted as the control unit 50. In this case, the lower surface of each of the first divided body 46 and the second divided body 47 is provided with a receptacle opening in the flow direction X. The relative movement of the first divided body 46 and the second divided body 47 can be restricted by inserting a common splint into the respective receptacles of the first divided body 46 and the second divided body 47.

  The lid 41 may be disassembled. In this case, instead of connecting the first divided body 46 and the second divided body 47 via the hinge member 49, they may be joined in a detachable manner via a magnet.

The height position of the upper surface 41 a of the lid 41 may not be equal to or more than the bottom height H 2 of the outlet 25. In this case, for example, the lid portion 41 is fitted in a portion (for example, the central portion or the upper end portion in the vertical direction Z in the mud reservoir 22) of the mud reservoir 22 separated upward from the bottom wall 31 May be adopted.
It is preferable that the gap between the lid 41 and the trout main body 21 or the mud reservoir 22 is not, for example, a passage of mosquitoes inhabiting the mud reservoir 22 or the like. However, a gap to the extent that the mosquito can not pass is acceptable, and specifically, there may be a gap having a width of 2 mm or less.
The rainwater mass 11 may be formed of concrete as in the rainwater mass 11A shown in FIGS. 13 to 18.

The deodorant equipped rainwater mass 90 shown in FIGS. 13 to 15 and the deodorant equipped rainwater mass 100 shown in FIGS. 16 to 18 are modifications of the deodorant equipped rainwater mass 80 according to the fourth embodiment. The rainwater mass 11A is provided on the crusher run 91 in each of the deodorant equipped rainwater masses 90, 100. The rainwater mass 11A includes a lower block 92, a middle block 93, an upper block 94, and an edge mass 95. The lower block 92, the middle block 93, the upper block 94, and the rim mass 95 are stacked in this order from the bottom to the top.
The lower block 92 is formed in a bottomed cylindrical shape and is disposed on the crusher run 91.
The middle block 93, the upper block 94 and the rim mass 95 are formed in a cylindrical shape that opens in the vertical direction Z. As shown in FIGS. 13 and 16, the outer shape of the edge mass 95 is formed in a rectangular shape in top view. The shape of the inner peripheral edge of the upper end opening of the edge mass 95 is also formed in a rectangular shape in top view.
In the rainwater mass 11A, the outlet 25 is formed on the side of the upper portion of the lower block 92, but the inlet 24 is not formed on the side. In other words, the side surface of the rainwater mass 11A has the outlet 25 but does not have the inlet 24. External rainwater and the like flow into the rainwater mass 11A through the inside of the peripheral mass 95, and the rainwater is discharged from the outlet 25.
The lower portion of the lower block 92 forms a mud reservoir 22 in the rainwater mass 11A. The upper part of the lower block 92, the middle block 93 and the upper block 94 form a mass main body 21. The rim mass 95 forms a riser 23.

  In addition, it is possible to replace components in the embodiment with known components as appropriate without departing from the spirit of the present invention, and the above-described modifications may be combined as appropriate.
