Description

Technology Field

[0001] The present invention relates to an odor blocking device for manholes or gratings, and more specifically, to an odor blocking device for manholes or gratings that is mounted on a manhole or grating to allow for the smooth inflow of sewage and rainwater, and when the inflow is finished, naturally blocks the inflow opening without any separate work to thoroughly block odors leaking from below, and enables the natural opening and closing of the opening door through the forward and backward rotation of a rotary roller. Background Technology

[0002] Typically, manholes or gratings allow rainwater to flow in from various sources, such as sewage generated from the outside, homes, companies, and factories, and then channel it to sewage treatment plants, rivers, or other facilities. Since the inside and outside of these manholes or gratings are connected, there is a problem where foul odors generated from sewers leak out to the outside. Consequently, various developments and attempts are being made to block these odors.

[0003] For example, according to Korean Registered Patent No. 1860890 (Prior Art 1), 'a drain hole connected to a sump; a grating horizontally seated on the upper edge of the drain hole and having vertical partitions formed at regular intervals; a stopper provided to intersect perpendicularly with the vertical partitions to stop the rotational movement of an opening / closing member; an opening / closing member that, when drainage pressure is applied from the upper part of the grating, rotates downward around a hinge and is stopped by the stopper to open the space between the vertical partitions, and when the drainage pressure is released, rotates upward around the hinge by the weight of a counterweight to restore to a horizontal state and closes the space between the vertical partitions; The present invention provides a device for preventing foreign matter inflow and blocking odors in a grating, comprising a rotation control member that is horizontally mounted on the vertical plate and, when a drainage pressure below a certain pressure acts on the upper part of the opening / closing member, a support ball supports the bottom surface of the braid of the opening / closing member to maintain the opening / closing member horizontally, and when the drainage pressure acting on the upper part of the opening / closing member is greater than the supporting force of the support ball, the braid is allowed to rotate freely downward. The rotation control member comprises: a housing mounted to maintain horizontality on the vertical plate of the grating, with one side open and the other side closed; a spring elastically mounted inside the housing; and a support ball coupled by a press fit on the open side of the housing.

[0004] However, although the foreign matter ingress prevention and odor blocking device of this grating blocked odors by restoring the opening and closing member to a horizontal state by rotating it upward around the hinge by the weight of the counterweight, there were cases where the opening and closing member could not be horizontal due to the support ball being pressed by the spring during restoration, so it was insufficient to prevent the leakage of fine odors.

[0005] As another example, according to Korean Registered Patent No. 2528179 (Prior Art 2), 'a lower manhole block (10) having a closed bottom surface, an open top surface, and a drain (11) formed so that a drain pipe (1) is connected to the side; an intermediate manhole block (20) assembled in stacks of at least one layer on the lower manhole block (10) and provided with an open top and bottom surface; an upper manhole block (30) assembled in stacks on the intermediate manhole block (20), with an open top and bottom surface and a trench (31) installed on the top surface; a joint part (40) that binds the lower manhole block (10), the intermediate manhole block (20), and the upper manhole block (30) to each other in a negative and positive structure on corresponding assembly surfaces; a sealing packing (50) installed between the joint parts (40) to block leakage and absorb vibration; and an odor trap (60) provided to block odors flowing back through the drain.The lower manhole block (10) and the middle manhole block (20) are combined, and a variable odor trap (80) is provided between the lower manhole block (10) and the middle manhole block (20). The variable odor trap (80) includes an elastic membrane (81) that divides the space between the lower manhole block (10) and the middle manhole block (20) with its edge portion engaged with a joint portion (40) that binds the lower manhole block (10) and the middle manhole block (20) in a negative and positive structure; a ring plate (83) installed in the center of the elastic membrane (81) through which a drainage hole (82) for discharging rainwater passes; a conical weight (84) provided to open and close the drainage hole (82) while moving downward from the upper part of the elastic membrane (81); and a link wire (86) having one end connected to the ring plate (83) and the other end connected to the conical weight (84) via a roller (85) installed in the trench (31). The elastic membrane (81) is pulled upward in a convex manner by the self-weight of the conical weight (84), and the drain hole (82) is closed by engaging with the conical weight (84). When the elastic membrane (81) protrudes upward in a convex manner, it forms a water collection space (81a) that temporarily stores rainwater by forming a downward slope angle toward the edge. When the weight of rainwater contained in the water collection space (81a) increases relative to the conical weight (84), the elastic membrane (81) protrudes downward in a convex manner due to the weight difference, and as the conical weight (84) moves upward, the drain hole (82) opens, and the rainwater contained in the water collection space (81a) is discharged all at once through the drain hole (82) and discharged through the drain (11) along with sediment on the bottom surface of the lower manhole block (10). As the drain hole (82) is closed by engaging with the conical weight (84), Presents an odor-blocking rainwater catchment manhole characterized by being equipped to block odor backflow.

[0006] However, although these odor-blocking stormwater manholes are designed so that a blocking plate rotates to discharge wastewater and rotates back to block it when there is no inflow, they are currently being used in a form that is far too conventional. Prior art literature

Specific details for implementing the invention

[0018] Hereinafter, preferred embodiments according to the present invention will be described in detail with reference to the attached drawings.

[0019] The present invention relates to an odor blocking device installed on a manhole or grating, and comprises a body (10), a discharge means (20), a control means (30), etc. as main components.

[0020] The body (10) according to the present invention is installed on the manhole or grating and is provided with an inlet (11) that penetrates vertically to allow various types of wastewater (1) flowing in from the outside, such as rainwater (2), to flow in. The body (10) is positioned below the manhole cover or grating and is provided with an inlet (11) to allow wastewater (1) and rainwater (2), etc. flowing in from the manhole and grating to flow in. In the case of the body (10), the inlet (11) may be formed in one or more shapes, and it may be formed at an angle so that the wastewater (1) and rainwater (2) can flow down, allowing the incoming wastewater (1) and rainwater (2), etc. to flow into the inlet (11) with smooth flow.

[0021] Additionally, the discharge means (20) according to the present invention is installed directly below the inlet (11) of the body (10) and is provided with an operating space (21) having an opening (22) that allows for discharge while accommodating a certain amount of various wastewater (1) and rainwater (2) that flow in. The discharge means (20) is provided with an opening (22) that allows for accommodating and containing various wastewater (1) and rainwater (2) that flow in through the inlet (11) formed in the body (10) described above, and for discharging the contained wastewater (1) and rainwater (2) downward.

[0022] At this time, the operating space (21) of the discharge means (20) is installed directly below the inlet (11) and is equipped with a receiving section (23) capable of accommodating a certain amount of various wastewater (1) and rainwater (2) flowing in, and a discharge section (24) capable of discharging, and is characterized by having an opening door (22) that rotates up and down by a hinge (25) on the receiving section (23). In the operating space (21) of the discharge means (20), a hinge (25) is formed in a separate upper direction on one side, and an opening door (22) capable of rotating up and down around the hinge (25) is formed in an inclined direction. Above the opening door (22), a receiving section (23) capable of accommodating a certain amount of various wastewater (1) and rainwater (2) flowing in from the inlet (11) is formed, and above the opening door (22), a discharge section (24) capable of discharging various wastewater (1) and rainwater (2) is formed.

[0023] Additionally, the control means (30) according to the present invention controls the opening and closing of the opening door (22) of the discharge means (20) to discharge various wastewater (1) and rainwater (2), or to block the inflow of odors (3). The control means (30) performs the role of controlling the discharge means (20) described above so that various wastewater (1) and rainwater (2), etc., can be discharged downwards by opening the opening door (22), or that odors (3) entering by closing the opening door (22) can be blocked.

[0024] At this time, the control means (30) is characterized by having a rotatable roller (31) that can rotate the open door (22) up and down as it approaches or moves away from the lower surface of the open door (22) in the operating space (21). The control means (30) is provided with a rotatable roller (31) so that one side of the open door (20) can be rotated around a hinge (25), allowing the other side to block or open the receiving portion (23). That is, the rotatable roller (31) is positioned at the lower side of the open door (22) to enable forward and backward movement, and rotates in the operating space (21) without a separate axis to approach or move away from the lower surface of the open door (22) to apply pressure, thereby enabling the opening and closing of the open door (22).

[0025] In addition, the above-mentioned control means (30) is characterized by a rotating roller (31) in the lower part of the operating space (21) that naturally presses the opening door (22) to rotate the opening door (22) upward to block the odor (3), and an inclined surface (32) in the shape of a certain angle of inclination that moves the rotating roller (31) from the load of various wastewater (1) and rainwater (2) contained on the closed opening door (22) to rotate the opening door (22) downward to discharge various wastewater (1) and rainwater (2). As described above, the control means (30) is positioned at the lower side of the open door (22) so that the rotating roller (31) can move closer or further away to press the lower surface of the open door (22), thereby enabling the open door (22) to be opened or closed. In the lower part of the operating space (21), an inclined surface (32) is formed on which the rotating roller (31) is tilted in the opposite direction of the hinge (25) of the open door (22). This structure allows the rotating roller (31) to naturally roll along the inclined surface (32) and press the lower surface of the open door (22). When the lower surface of the open door (22) is pressed in this way, the open door (22) can be automatically closed so that the odor (3) entering from the bottom is not discharged to the outside. However, as the sewage (1) and rainwater (2) that have entered through the inlet (11) of the body (10) are gradually received at the upper part of the open door (22) when the open door (22) is closed, a certain load is generated, and as the rotating roller (31) is pushed by that load, the open door (22) is opened and the various sewage (1) and rainwater (2) fall down. Then, as there is no load from the fallen sewage (1) and rainwater (2), the rotating roller (31) naturally rides along the inclined surface (32) and presses the lower surface of the open door (22), thereby closing the open door (22) and blocking the odor (3).

[0026] Additionally, the above-mentioned control means (30) is characterized by further comprising a stopper (33) protruding to limit the movement radius of the rotating roller (31) on the opening door (22). The rotating roller (31) of the control means (30) rotates to press the opening door (22) to close it or to move away from the opening door (22) to open it. In order to set such an appropriate rotation radius, a stopper (33) protruding from the lower surface of the opening door (22) is further provided.

[0027] In addition, the rotating roller (31) of the above-mentioned control means (30) is characterized by having one or more friction surfaces (34) to minimize the contact area with the inclined surface (32) on its outer circumference, thereby reducing friction and increasing the rotation rate. Since the rotating roller (31) must rotate while seated on the inclined surface (32), frictional force may be generated, and due to this frictional force, it may not slide even when a load such as various wastewater (1) or rainwater (2) is generated. Therefore, to reduce frictional force with the inclined surface (32), one or more friction surfaces (34) are formed on the outer circumference of the rotating roller (31) to reduce friction and ensure smooth operation.

[0028] Additionally, the above-mentioned adjustment means (30) is characterized by having a guide protrusion (35) on the rotating roller (31) and a guide groove (36) on the inclined surface (32) so that the rotating roller (31) can move accurately on the inclined surface (32) without any misalignment in the direction of rotation. When the rotating roller (31) moves forward or backward on the inclined surface (32), if the rotating roller (31) rotates in a misaligned state, the pressure applied to the opening door (22) is reduced, which may cause difficulty in operation. Therefore, a guide protrusion (35) is formed on the rotating roller (31) and a guide groove (36) is formed on the inclined surface (32). Since the guide protrusion (35) moves along the guide groove (36), the rotating roller (31) does not apply pressure to only a part of the opening door (22), thereby enabling smooth operation. In addition, the present invention is configured such that a guide protrusion (35) is provided on the rotating roller (31) and a guide groove (36) is provided on the inclined surface (32) so that the guide protrusion (35) is inserted into the guide groove (36), but conversely, a configuration in which a guide groove (36) is formed on the rotating roller (31) and a guide protrusion (35) is provided on the inclined surface (32) is also possible.

[0029] Thus, the present invention provides the effect of enabling the smooth inflow of sewage and rain, etc., by being mounted on a manhole or grating, and then naturally blocking the inflow opening without any separate work once the inflow is finished, thereby thoroughly blocking odors leaking from below, and allowing the opening door to be opened and closed naturally through the forward and backward rotation of a rotary roller.

[0030] It is obvious to those skilled in the art that the present invention is not limited to the described embodiments and can be modified and varied in various ways without departing from the spirit and scope of the invention. Accordingly, such variations or modifications should be considered to fall within the scope of the claims of the present invention. Explanation of the symbols
