Referring to fig. 1 to 5, a manhole malodor preventing apparatus 100 according to the present embodiment is applied to a manhole covered at an upper portion with a grating 10 and communicating with a pipe, the manhole malodor preventing apparatus 100 including a malodor preventing casing part 110 and a malodor blocking part 120.
The grill 10 includes a peripheral edge 11 forming a periphery and an inner partition body 12 formed in a lattice shape inside the peripheral edge 11.
In the present embodiment, the entire grating 10 is shown in a rectangular parallelepiped form, but it is an example, and various forms may be provided according to the form of the manhole.
The malodor prevention casing part 110 is disposed at a lower side of the grill 10 to communicate the outside of the grill 10 with the duct, and the malodor prevention casing part 110 includes a casing main body 111 and a middle partition wall 112.
The jacket main body 111 is a shape penetrating in the vertical direction, and in the present embodiment, a rectangular parallelepiped box shape with its upper end and lower end opened is proposed as an example.
The middle partition wall 112 is divided across the center of the jacket main body 111, and the middle partition wall 112 is formed in a plate shape as a whole across the center of the jacket main body 111 in the longitudinal direction of the jacket main body 111, thereby dividing the inner space of the jacket main body 111 into two parts.
Reference numeral 113 is a grill placement flange extending with a certain width in a peripheral direction along an upper end of the jacket main body 111.
Reference numeral 114 is a spindle penetration hole formed through the casing main body 111 so as to rotatably penetrate a malodor blocking spindle 121 described later.
The hinge through holes 114 are formed two by two on each side of the jacket main body 111 so as to be symmetrical with each other with respect to the middle partition wall 112.
The malodor blocking member 120 is disposed inside the malodor prevention casing part 110 so that rainwater (rainwater) flowing from the outside of the grill 10 flows into the duct through the malodor prevention casing part 110 by its own weight (self load) and blocks malodor from being emitted from the duct to the outside of the grill 10, and at the same time, when the duct is filled with the rainwater and the rainwater flows backward from the duct, the rainwater flowing backward can be discharged to the outside of the grill 10, and the malodor blocking member 120 includes a pair of malodor blocking shafts 121 and a pair of malodor blocking blades 122.
The respective malodor blocking rotating shafts 121 are configured to pass through the casing main body 111 to be parallel to the middle partition walls 112, respectively, and to be symmetrical to each other with the middle partition walls 112 interposed therebetween, and the respective malodor blocking rotating shafts 121 are rotatably coupled to the casing main body 111 by penetrating the rotating shaft penetration holes 114.
The respective malodor blocking blades 122 extend toward both sides of the respective malodor blocking rotating shafts 121, and are formed in a plate shape extending in a certain area toward both sides of the respective malodor blocking rotating shafts 121. That is, each of the malodor blocking blades 122 is formed in a rectangular plate shape, and each of the malodor blocking shafts 121 is formed to penetrate the middle of each of the malodor blocking blades 122 in the longitudinal direction of each of the malodor blocking blades 122.
One end of each of the malodor blocking blades 122 is in contact with a lower portion of one of the casing main body 111 and the middle partition wall 112, and the other end of each of the malodor blocking blades 122 is in contact with an upper portion of the other of the casing main body 111 and the middle partition wall 112, whereby each of the malodor blocking blades 122 is slantly disposed in a slanted state between the casing main body 111 and the middle partition wall 112 to block in a slanted state between the casing main body 111 and the middle partition wall 112, whereby the malodor from the duct is blocked by the malodor blocking member 120 from being emitted to the outside of the grill 10.
Preferably, each lower end of each of the malodor blocking blades 122 is in contact with a lower portion of the middle partition wall 112, and each upper end of each of the malodor blocking blades 122 is in contact with an upper portion of the casing main body 111, whereby each of the malodor blocking blades 122 is slantly arranged in a slanted form to be gradually downward from the casing main body 111 toward the middle partition wall 112, so that each of the malodor blocking blades 122 blocks between the casing main body 111 and the middle partition wall 112 in a slanted form in a V-shape, whereby the malodor from the duct is dividedly received in each of lower spaces of the malodor blocking blades 122 divided from each other, so that the rising force of the malodor can be relatively weakened.
The edge portion of each malodor blocking blade 122 is made of a relatively soft material such as silicone rubber, so that the each malodor blocking blade 122 does not rub against the intermediate partition wall 112 and the casing main body 111.
The rainwater flowing in from the outside of the grill 10 flows down along the inclined upper surface of each malodor blocking blade 122 to be collected on the inclined lower upper surface of each malodor blocking blade 122, and when the rainwater collected on the inclined lower upper surface of each malodor blocking blade 122 is collected to a certain amount or more, the respective malodor blocking blades 122 rotate by the weight of the rainwater to make the lower portion of each malodor blocking blade 122 face the duct, and at the same time, the space between the casing main body 111 and the intermediate partition wall 112 is opened, so that the rainwater can flow into the duct.
In addition, in the present embodiment, when the rainwater fills the duct and the rainwater flows backward from the duct, the rainwater flowing backward from the duct lifts the inclined upper bottom surface of each malodor blocking blade 122, so that each malodor blocking blade 122 rotates to direct the lower portion of each malodor blocking blade 122 toward the duct, and at the same time, the casing main body 111 and the intermediate partition wall 112 are in an open state, so that the rainwater flowing backward from the duct can be discharged to the outside of the grill 10.
In one aspect, the malodor blocking part 120 includes a hooking part 124 formed on an upper surface of the malodor blocking blade 122, and the manhole malodor preventing apparatus 100 may include a catching part 130 connecting the grating 10 and the hooking part 124.
The hanging part 124 is formed at a portion of the upper surface of the malodor blocking blade 122 which is relatively located at an upper side with reference to the malodor blocking rotating shaft 121.
As an example, the hanging part 124 may be formed to protrude in a ring shape on the upper surface of the malodor blocking blade 122.
In detail, the locking member 130 includes a grill locking portion 131 locked to the grill 10, a hook portion 133 hooked to the hooking portion 124, and an elasticity providing connecting portion 132 connecting the grill locking portion 131 and the hook portion 133 and providing elasticity.
The grill locking part 131 and the hooking part 133 may be formed in a hook shape to be hooked on the grill 10 and the hooking part 124, respectively, and the elasticity providing part 132 may be formed in a tension spring shape.
The grill 10 and the hanging part 124 are connected by the locking member 130, so that the rotation state of the malodor blocking member 120 can be maintained, and thus the open state between the casing main body 111 and the intermediate partition wall 112 can be continuously maintained as needed.
As described above, the manhole malodor preventing apparatus 100 includes the malodor preventing casing part 110 and the malodor blocking part 120, so that it is possible to prevent the malodor in the pipe from flowing backward and to allow the rainwater to flow into the pipe, and at the same time, when the pipe is filled with the rainwater due to an excessive precipitation amount, to allow the rainwater to flow backward from the pipe and to prevent vermin such as mosquitoes from falling into the pipe.
Hereinafter, the operation of the manhole malodor preventing apparatus 100 according to the present embodiment will be described with reference to the accompanying drawings.
First, before the rainwater is supplied more than a certain amount, as shown in fig. 2, both ends of each malodor blocking blade 122 are inclined to contact each of the casing main body 111 and the middle partition wall 112. In this manner, the space between the casing main body 111 and the middle partition wall 112 is blocked in an inclined form by the respective malodor blocking blades 122, whereby the malodor from the duct is blocked by the malodor blocking member 120 to prevent the malodor from being emitted to the outside of the grill 10.
Then, the rainwater flowing in from the outside of the grill 10 flows down along the inclined upper surface of each malodor blocking blade 122 and is collected on the inclined lower upper surface of each malodor blocking blade 122, and when the rainwater collected on the inclined lower upper surface of each malodor blocking blade 122 is collected to a certain amount or more, as shown in fig. 3 and 4, the respective malodor blocking blades 122 rotate by the weight of the rainwater to direct the lower portion of each malodor blocking blade 122 toward the duct, and at the same time, the space between the casing main body 111 and the intermediate partition wall 112 is opened, and thus the rainwater falls down and can flow into the duct.
On the one hand, as shown in fig. 2, both ends of each of the malodor blocking blades 122 are inclined to be in contact with each of the casing main body 111 and the middle partition wall 112, and then when the rainwater fills the pipe due to excessive rain in a plum rain season or the like and the rainwater flows backward from the pipe, the inclined upper bottom surface of each of the malodor blocking blades 122 is lifted up by the rainwater flowing backward from the pipe, so that as shown in fig. 3 and 4, each of the malodor blocking blades 122 is rotated to direct the lower portion of each of the malodor blocking blades 122 toward the pipe, and at the same time, the space between the casing main body 111 and the middle partition wall 112 is opened, whereby the rainwater flowing backward from the pipe can be discharged to the outside of the grill 10.
Modes for carrying out the invention
Hereinafter, a manhole malodor preventing apparatus according to other embodiments of the present invention will be described with reference to the accompanying drawings. In the above description, the description overlapping with the contents already described in the first embodiment of the present invention is replaced with the above description, and is omitted here.
Fig. 6 is a sectional view showing a constitution of a manhole malodor preventing apparatus according to a second embodiment of the present invention, fig. 7 is an enlarged view of a portion B illustrated in fig. 6, and fig. 8 is an enlarged view showing a state where a malodor blocking member illustrated in fig. 7 is opened.
Referring to fig. 6 to 8 together, in the present embodiment, the malodor blocking member 220 includes a first elastic deformation body 225, a first contact portion 227, a second elastic deformation body 226, and a second contact portion 228.
In addition, in the present embodiment, the malodor prevention casing part 210 includes a casing main body 211, an upper side extension 215, and a lower side extension 216.
The first elastic deformation body 225 is formed inside the malodor prevention casing part 210 to be gradually downward toward the duct, and is formed of rubber or the like so as to be elastically deformable.
The first contact portion 227 is formed at a lower portion of the first elastic deformation body 225, and the first contact portion 227 is formed of rubber or the like, so that it can be integrally formed with the first elastic deformation body 225.
The second elastic deformation body 226 is formed inside the malodor prevention casing part 210 to be gradually downward toward the duct and to be symmetrical to the first elastic deformation body 225, and the second elastic deformation body 226 is formed of rubber or the like so as to be elastically deformable.
The second contact portion 228 is formed at a lower portion of the second elastic deformation body 226, and the second contact portion 228 may be formed integrally with the second elastic deformation body 226 by being formed of rubber or the like.
The first elastic deformation body 225 and the second elastic deformation body 226 are configured to gradually converge toward each other as they go down toward the duct, so that the first elastic deformation body 225 and the second elastic deformation body 226 are integrally formed in a funnel shape, and as shown in fig. 6 and 7, the first contact portion 227 and the second contact portion 228 are maintained in a state of being in contact with each other by the elastic force of the first elastic deformation body 225 and the second elastic deformation body 226, so that the malodor from the duct is blocked by the malodor blocking member 220 and prevented from being emitted to the outside of the grill.
The malodor blocking member 220 is formed as described above, so that rainwater flowing from the outside of the grill flows down along the respective upper surfaces of the first elastic deformation body 225 and the second elastic deformation body 226 and is collected on the respective upper surfaces of the first elastic deformation body 225 and the second elastic deformation body 226, and when the rainwater collected on the respective upper surfaces of the first elastic deformation body 225 and the second elastic deformation body 226 is collected to a certain amount or more, as shown in fig. 8, the first elastic deformation body 225 and the second elastic deformation body 226 that are deformed are elastically deformed by the own weight of the rainwater, and at the same time, the first contact portion 227 and the second contact portion 228 are spaced apart from each other, so that the casing main body 211 is in an open state, and the rainwater can flow down and flow into the duct.
When the rainwater fills the pipe and the rainwater flows backward from the pipe, the rainwater flowing backward from the pipe presses the first elastic deformation body 225 and the second elastic deformation body 226 upward, and elastically deforms the first elastic deformation body 225 and the second elastic deformation body 226, so that the first contact portion 227 and the second contact portion 228 are spaced apart from each other, whereby the casing main body 211 is in an open state, and the rainwater flowing backward from the pipe can be discharged to the outside of the grid.
The cover body 211 is formed to penetrate in the vertical direction.
The upper extension 215 extends a certain length toward the inside of the jacket main body 211 at the inner surface of the jacket main body 211, and the upper extension 215 extends perpendicularly from the inner surface of the jacket main body 211.
The lower extension 216 is extended in a certain length toward the inside of the jacket main body 211 at the inner surface of the jacket main body 211, and is formed in parallel to be spaced apart from the upper extension 215.
One end portion of the first elastic deformation body 225 and the second elastic deformation body 226 is inserted between the upper extension body 215 and the lower extension body 216, so that the malodor blocking part 220 may be fixed at the malodor prevention casing part 210.
When three or more of the malodor barrier members 220 are applied to the inside of the malodor prevention casing part 210, the terminal end portion of one of the first elastic deformation body 225 and the second elastic deformation body 226 of two of the malodor barrier members 220 existing at both sides outermost periphery among the three or more malodor barrier members 220 is each inserted between the upper side extension body 215 and the lower side extension body 216, and the first elastic deformation body 225 and the second elastic deformation body 226 adjacent to each other of the remaining malodor barrier members 220 except for two existing at both sides outermost periphery among the three or more malodor barrier members 220 constitute a form in which they are connected to each other. As such, in the malodor blocking part 220, the opening occurs between the first contact portion 227 and the second contact portion 228 at a plurality of places, so that the falling of the rainwater or the reverse flow of the rainwater can be completed.
In one aspect, the manhole malodor preventing apparatus according to the present embodiment further includes a lower escape preventing member 240 and an upper escape preventing member 250.
The downward separation preventing member 240 is connected to the casing main body 211 and supports an upper bottom surface of at least one of the first elastic deformation body 225 and the second elastic deformation body 226 so as to prevent the malodor blocking member 220 from being separated downward toward the pipe side.
The downward escape preventing member 240 may be configured in a plate state extending a certain length in an upward and downward direction to be able to support an upper bottom surface of at least one of the first elastic deformation body 225 and the second elastic deformation body 226.
The upper escape prevention part 250 is connected to the jacket main body 211 and presses an upper portion of at least one of the first elastic deformation body 225 and the second elastic deformation body 226 to be able to prevent the malodor blocking part 220 from escaping upward toward the grill side.
The upper detachment prevention member 250 includes: an upper separation preventing connector 251 connected to the cover body 211 and made of a metal material; and an upper separation preventing elastic body 252 made of an elastic material such as rubber so as to surround the upper separation preventing connection body 251 and contact an upper surface of at least one of the first elastic deformation body 225 and the second elastic deformation body 226.
The upper separation preventing elastic body 252 is not in contact with the jacket main body 211 but with the upper surface of at least one of the first elastic deformation body 225 and the second elastic deformation body 226, and thus the upper separation preventing connection body 251 is not in direct contact with the upper surface of at least one of the first elastic deformation body 225 and the second elastic deformation body 226, so that the upper surface of at least one of the first elastic deformation body 225 and the second elastic deformation body 226 may not be damaged.
The lower separation prevention member 240 and the upper separation prevention member 250 are located on the same line up and down with respect to the direction of gravity with at least one of the first elastic deformation body 225 and the second elastic deformation body 226 interposed therebetween.
Hereinafter, the operation of the manhole malodor preventing apparatus according to the present embodiment will be described with reference to the accompanying drawings.
First, before the rainwater is supplied to a certain amount or more, as shown in fig. 6 and 7, the first contact portion 227 and the second contact portion 228 are brought into a state of contacting each other, so that the malodor blocking member 220 is brought into a closed state, whereby the malodor from the duct is blocked by the malodor blocking member 220 to prevent the emission to the outside of the grill.
Then, the rainwater flowing in from the outside of the grill flows down along the upper surface of the malodor blocking member 220 and is collected on the upper surface of the malodor blocking member 220, and when the rainwater collected on the upper surface of the malodor blocking member 220 is collected to a certain amount or more, as shown in fig. 8, the first contact portion 227 and the second contact portion 228 are released from contact by the self weight of the rainwater, and the malodor blocking member 220 is opened, and thus the rainwater falls and can flow into the duct.
On the other hand, as shown in fig. 6 and 7, when the rainwater fills the pipe due to excessive rain in a rainy season or the like after the state in which the malodor blocking member 220 is closed is maintained and the rainwater flows backward from the pipe, the rainwater flowing backward from the pipe lifts the malodor blocking member 220 downward, so that the contact between the first contact portion 227 and the second contact portion 228 is released and the malodor blocking member 220 is opened, whereby the rainwater flowing backward from the pipe can be discharged to the outside of the grill.
Hereinafter, a manhole malodor preventing apparatus according to a third embodiment of the present invention will be described with reference to the accompanying drawings. In the above description, the description overlapping with the contents already described in the first and second embodiments of the present invention is replaced with the above description, and is omitted here.

The elevating body 381 ascends and descends in the vertical direction in the lower spaces of the first and second elastic deformation bodies 325 and 326 constituting the malodor blocking member 320, the upper portion of the elevating body 381 is opened and both ends of the upper portion of the elevating body 381 face each other in a spaced state, the lower portion of the elevating body 381 is connected in a "U" shape, and a rainwater penetration hole 382 for penetration of rainwater is formed in the lower portion of the elevating body 381.
The buoyancy forming body 383 is connected to the lift body 381, and is sealed in a state in which a buoyancy forming gas such as air is filled in the buoyancy forming body 383, thereby forming buoyancy.
The buoyancy forming body 383 floats on the water surface of the pipe, so that the lifting body 381 connected to the buoyancy forming body 383 also floats on the water surface of the pipe, and thus the lifting body 381 is lifted together with the lifting of the water level in the pipe, and at the same time, is relatively close to the malodor blocking member 320 or is relatively spaced from the malodor blocking member 320.
The slide elevating body 385 is formed to be long by a predetermined length in the vertical direction at a predetermined interval from the elevating body 381, and the slide elevating body 385 is elevated while being guided in the vertical direction along the elevation guide member 370, specifically, along a slide elevating hole 373 to be described later.
The elevating connector 384 is used for connecting the sliding elevating body 385 and the elevating main body 381.
The elevation guide member 370 extends downward from the bottom surface of the malodor prevention housing part 310 by a predetermined length to guide the elevation of the elevation member 380, and the elevation guide member 370 includes an elevation guide body 371, a sliding elevation hole 373, and an elevation connection through hole 372.
The elevation guide 371 extends from the bottom surface of the malodor prevention housing part 310 downward, i.e., vertically, to a predetermined length.
The sliding lift hole 373 is formed inside the lift guide 371 along the longitudinal direction of the lift guide 371, and the sliding lift body 385 moves up and down while being guided along the sliding lift hole 373.
The elevation connection hole 372 is formed to be long and vertically penetrated through a surface of the slide elevation hole 373 facing the elevation body 381, and the elevation connection body 384 can be elevated in a penetrated state.
The malodor blocking side permanent magnet 365 is formed of a pair so as to be combined one at each periphery of the first contact portion 327 and the second contact portion 328 constituting the malodor blocking member 320, and is disposed to be opposite to each other between different polarities. For example, the N-pole of the permanent magnet 365 coupled to the outer periphery of the first contact portion 327 of the permanent magnet 365 on the malodor blocking side is disposed toward the contact surface between the first contact portion 327 and the second contact portion 328, and the S-pole of the permanent magnet 365 coupled to the outer periphery of the second contact portion 328 of the permanent magnet 365 on the malodor blocking side is disposed toward the contact surface between the first contact portion 327 and the second contact portion 328. In this way, the pair of malodor blocking permanent magnets 365 attract each other, and the first contact portion 327 and the second contact portion 328 can maintain a state of being in contact with each other.
The elevating permanent magnet 360 is formed of a pair of magnets so as to be respectively coupled to both end portions of the upper portion of the elevating body 381, which are opposite to each other in a spaced state, and the elevating permanent magnet 360 is opposite to the malodor blocking side permanent magnet 365 to affect each other in a relatively raised state of the elevating body 381, and the elevating permanent magnet 360 is opposite to the malodor blocking side permanent magnet 365 to not affect each other in a relatively lowered state of the elevating body 381.
The elevating permanent magnet 360 is configured to have a relatively stronger magnetic force than the malodor blocking side permanent magnet 365.
In the present embodiment, in the pair of the elevating permanent magnets 360 and the pair of the malodor blocking side permanent magnets 365, the magnets facing each other are arranged to have different polarities from each other. For example, when the north pole of the permanent magnet 365 of the malodor blocking side coupled to the periphery of the first contact portion 327 of the malodor blocking side permanent magnet 365 is disposed toward the contact surface of the first contact portion 327 and the second contact portion 328, the south pole of the permanent magnet 365 of the malodor blocking side coupled to the periphery of the second contact portion 328 of the malodor blocking side permanent magnet 365 is disposed toward the outside of the first contact portion 327, the south pole of the permanent magnet 365 of the malodor blocking side coupled to the periphery of the second contact portion 328 of the malodor blocking side permanent magnet 365 is disposed toward the contact surface of the first contact portion 327 and the second contact portion 328, the south pole of the permanent magnet 365 of the malodor blocking side coupled to the periphery of the second contact portion 328 of the malodor blocking side permanent magnet 365 is disposed toward the outside of the second contact portion 328, the N-pole of the lifting permanent magnet 360, which faces the periphery of the first contact portion 327, of the lifting permanent magnet 360 is disposed toward the first contact portion 327, and the S-pole of the lifting permanent magnet 360, which faces the periphery of the second contact portion 328, of the lifting permanent magnet 360 is disposed toward the second contact portion 328.
With the above configuration, as shown in fig. 9, in a state where the elevating body 381 is lowered, the elevating permanent magnets 360 and the malodor blocking permanent magnets 365 are spaced apart from each other in an opposed manner, so that an attractive force between the pair of malodor blocking permanent magnets 365 acts relatively stronger than an attractive force between the elevating permanent magnets 360 and the malodor blocking permanent magnets 365 to be opposed to each other, and thus the pair of malodor blocking permanent magnets 365 attract each other while the first contact portion 327 and the second contact portion 328 maintain a state of contacting each other, and the malodor blocking member 320 is in a closed state.
Then, the water level in the pipe rises, as shown in fig. 10, when the lifting body 381 is in a raised state, the lifting permanent magnets 360 and the malodor blocking side permanent magnets 365 approach each other relatively, so that the attractive force between the respective lifting permanent magnets 360 and the respective malodor blocking side permanent magnets 365 facing each other is relatively stronger than the attractive force between the pair of malodor blocking side permanent magnets 365, and the respective lifting permanent magnets 360 and the respective malodor blocking side permanent magnets 365 facing each other are respectively attracted to each other, whereby the respective first contact portions 327 and the second contact portions 328 are respectively spaced apart relatively in a direction away from each other, and at the same time, the contact of the first contact portions 327 and the second contact portions 328 is released, so that the malodor blocking member 320 becomes an opened state.
Hereinafter, the operation of the manhole malodor preventing apparatus according to the present embodiment will be described with reference to the accompanying drawings.
First, before a certain amount of rainwater is supplied, as shown in fig. 9, the elevating member 380 is maintained in a descending state, the first contact portion 327 and the second contact portion 328 are brought into a state of contacting each other by the attraction force between the pair of malodor blocking side permanent magnets 365, and the malodor blocking member 320 is brought into a closed state, so that the malodor from the duct is blocked by the malodor blocking member 320 and prevented from being emitted to the outside of the grill.
Then, the rainwater flowing in from the outside of the grill flows down along the upper surface of the malodor blocking member 320 and is collected on the upper surface of the malodor blocking member 320, and when the rainwater collected on the upper surface of the malodor blocking member 320 is collected to a certain amount or more, the first contact portion 327 and the second contact portion 328 are released from contact by the self weight of the rainwater, and the malodor blocking member 320 is opened, whereby the rainwater falls and can flow into the duct.
On the one hand, when the rainwater fills the pipe due to excessive rain in a rainy season or the like while the stink blocking member 320 is kept closed, and the rainwater flows backward from the pipe, the water level in the pipe rises, and the elevating member 380 is guided by the elevating guide member 370 and ascends as shown in fig. 10, so that the respective elevating permanent magnets 360 and the respective stink blocking permanent magnets 365 facing each other attract each other, and the contact between the first contact portion 327 and the second contact portion 328 is released, whereby the stink blocking member 320 is in an open state, and the rainwater flowing backward from the pipe can be discharged to the outside of the grill.
Fig. 11 is a sectional view enlarging a state in which a flange opening and closing member constituting a manhole malodor preventing apparatus according to a fourth embodiment of the present invention is closed, and fig. 12 is a sectional view enlarging a state in which the flange opening and closing member illustrated in fig. 11 is opened.
Referring to fig. 11 together with fig. 12, in the present embodiment, a flange penetration hole 495 is penetratingly formed at a grill installation flange 413, the grill installation flange 413 extends in a certain width in a peripheral direction along an upper end of a jacket main body 411 constituting a malodor prevention jacket part, and the manhole malodor prevention apparatus according to the present embodiment further includes a flange opening and closing part 490.
The flange opening/closing member 490 may open and close the flange penetration hole 495, and the flange opening/closing member 490 includes a flange opening/closing body 491 and a flange opening/closing elastic body 492.
The flange opening/closing body 491 is capable of closing or opening the flange penetration hole 495 at a bottom surface of the flange penetration hole 495, and the flange opening/closing body 491 is formed in a plate shape capable of covering an area of the flange penetration hole 495.
The flange opening/closing elastic body 492 connects the flange opening/closing body 491 and the grill mounting flange 413, and provides elasticity, and as an example of the flange opening/closing elastic body 492, a plate spring may be proposed.
In the above configuration, as shown in fig. 11, the flange opening/closing body 491 is normally kept in a state of closing the flange penetration hole 495 by the flange opening/closing elastic body 492.
Then, when water is accumulated in the grill mounting flange 413 due to rain or the like, as shown in fig. 12, the flange opening/closing elastic body 492 is elastically deformed by the self weight of the water accumulated in the grill mounting flange 413, and at the same time, the flange opening/closing body 491 is lowered, whereby the flange penetration hole 495 is opened, and the water accumulated in the grill mounting flange 413 can be discharged.
When the drain of the water accumulated in the grill mounting flange 413 is completed, the flange opening/closing body 491 is in a state of closing the flange penetration hole 495 again by the restoring force of the flange opening/closing elastic body 492.
Fig. 13 is a sectional view enlarging a part of the constitution of a manhole malodor preventing apparatus according to a fifth embodiment of the present invention.
Referring to fig. 13, in the present embodiment, a shaft fixing sleeve 501 is protruded at a casing main body 511, so that a malodor blocking rotation shaft 521 is rotatably connected to the shaft fixing sleeve 501.
In addition, a shaft elasticity providing unit 502 is connected to the malodor blocking rotation shaft 521, so that the malodor blocking rotation shaft 521 maintains a rotated state by the shaft elasticity providing unit 502 to allow the malodor blocking blade 522 to obliquely block the casing main body 511.
When the malodor blocking rotation shaft 521 rotates to cause the malodor blocking blade 522 to open the casing main body 511, a restoring force is gathered at the shaft elasticity providing unit 502, and then the malodor blocking rotation shaft 521 rotates again to a home position by the restoring force of the shaft elasticity providing unit 502, whereby the malodor blocking blade 522 maintains a state of blocking the casing main body 511 again obliquely.
As the shaft elasticity providing unit 502, a torsion spring may be proposed, in which the shaft elasticity providing unit 502 is in a state of being wound around the malodor blocking rotation shaft 521, one end of the shaft elasticity providing unit 502 is fixed to the malodor blocking rotation shaft 521, and the other end of the shaft elasticity providing unit 502 is fixed to the shaft fixing sleeve 501.
On one hand, a shaft rotation limiting stopper 504 limiting the rotation range of the malodor blocking rotation shaft 521 is formed at the shaft fixing bushing 501 to prevent the turning-over phenomenon of the malodor blocking blade 522 occurring when the malodor blocking rotation shaft 521 rotates more than vertical.
The shaft rotation limiting stopper 504 protrudes from the shaft fixing sleeve 501 by a certain length, passes through the center of the malodor blocking rotation shaft 521, and is disposed on an imaginary line formed toward the gravity direction.
The rotation range of the malodor blocking rotation shaft 521 is limited by the shaft rotation limiting stopper 504 so that the malodor blocking blade 522 may not be turned over.
In one aspect, a weight 503 is further provided to the malodor blocking blade 522 so that the malodor blocking shaft 521 maintains a rotated state by the weight of the weight 503 to allow the malodor blocking blade 522 to obliquely block the casing main body 511.
