Description

Drainage guide device {Apparatus for guide of drain}

The present invention relates to a drainage guide device, and more particularly, a drainage guide device provided in the ground or a sewer pipe to guide discharge of sewage and to prevent odors, and to selectively allow odors or sewage in the drainage to flow back to the ground. It is about.

In general, a plurality of drainage guide devices are provided in sewers or drainage channels, etc., which are embedded in roadsides, to guide drainage to the lower side of the road so that wastewater, such as drainage, is discharged through sewers in the ground.

However, such drainage guide device is usually formed to have only the function of flowing the sewage of the ground. Therefore, the odor of the basement or the sewer is usually released through the hole through which the sewage flows, thereby harming the human environment living on the ground.

Accordingly, in recent years, drainage guide devices have been developed to guide the discharge of sewage and, at the same time, shut off drains so that the odors of the drains are not ejected to the ground.

However, these conventional devices are simply configured to completely block the odor from being discharged to the ground, rather, the odor generated in the basement flows back to the home, etc. through the pipe and explosion of various toxic gases in the sewers There is concern.

In addition, when using a conventional drainage device, there is a problem that damage occurs when water flows back due to heavy rain or the like. That is, when the water in the basement or the sewer flows to the ground due to heavy rain or the like, the fastening part such as the hinge (hinge) provided on the backflow plate collides with the foreign matter such as the rod due to the strong backflow pressure. have.

SUMMARY OF THE INVENTION An object of the present invention is to solve the problems of the prior art as described above, while drainage is to be discharged through the drainage hole, while the drainage hole is normally shielded to provide a drainage guide device to prevent odor ejection of the drain. will be.

Another object of the present invention is to provide a drainage guide device in which when the underground water flows backward, the backflow hole and the drainage hole are simultaneously opened so that the water is naturally spouted upwards.

Still another object of the present invention is to provide a drainage guide device in which foreign matter does not adhere to the surface by the adhesion preventing means formed on the surface, and flows down with the sewage to prevent clogging.

Still another object of the present invention is to allow natural discharge of odor through the left incision hole of the adhesion preventing means, to prevent the problem of odor backflow and gas explosion to the residential area.

Drainage guide device according to the present invention for achieving the above object,

A mounting plate seated in the ground or sewer pipe or drainage channel; A bottom plate provided to be inclined at a lower side of the mounting plate to guide the flow of the drainage; A side plate which is formed between the mounting plate and the bottom plate to support the bottom plate, and guides the upper drainage to be collected to the upper side of the bottom plate; A drainage hole formed between the mounting plate and the bottom plate to be a passage through which the sewage collected to the upper side of the bottom plate is drained; A drain cover rotatably installed at one side of the bottom plate to selectively shield the drain hole; A backflow hole formed to penetrate the bottom plate vertically so as to be a passage through which the sewage of the bottom plate is flowed back to the bottom plate; A backflow cover provided at one side of the bottom plate to selectively shield the backflow hole; And an adhesion preventing means protruding upward from an upper surface of the bottom plate to prevent foreign matter from being attached to the upper surface of the bottom plate.

According to the drainage guide apparatus of the present invention as described above, there are various effects.

First, there is an advantage that the drainage is made smoothly and at the same time prevent the emission of odor. That is, in the present invention, the drain cover is opened and closed by its own weight to guide the flow of sewage, and when the sewage does not flow, the drain hole is automatically shielded. Therefore, there is an advantage that the odor of the drain through the drain hole is prevented from being emitted to the ground.

Secondly, in the present invention, a backflow cover and a backflow hole are provided to guide the backflow of water. Therefore, when the water pressure in the basement is increased, the backflow cover is naturally opened to reverse the water flow. Therefore, there is an effect that a problem that the drainage guide device is damaged by the water blown by heavy rain or the like is prevented.

Third, in the present invention, the adhesion preventing means is formed on the surface. Therefore, since the adhesion preventing means prevents the adhesion of the foreign matter, the discharge of the foreign matter is made smoothly, there is an advantage that the clogging of the drain hole due to the foreign matter.

Fourth, in the present invention, the adhesion preventing means is formed by protruding a part from the bottom plate. Therefore, since the cutout of a predetermined size is formed in the bottom plate, the odor is usually distributed through the cutout. That is, a small amount of malodor is blown out through a small incision hole and dispersed in the air. As such, there is an effect of dispersing the odor and dissipation, so that the odor of the sewer can be smoothly removed (that is, since the odor of the sewer must be ejected to the ground somewhere, it is not all-around to block the odor. Most preferably, the present invention is diluted and discharged in a small amount in the air within the range that does not harm the living environment. Backflow and explosion of toxic gases are prevented.

Fifth, in the present invention, since the backflow hole is formed in the depression of the bottom plate, the backflow hole and the backflow cover are spaced apart by a predetermined distance. Accordingly, even when water flows backward from the bottom of the bottom plate and foreign substances such as sticks collide with the backflow hole, the opening and closing of the backflow cover is not affected. That is, when the foreign matter hits the bottom surface of the depression, the periphery of the backflow hole protrudes upwards. In this case, since there is a gap between the backflow hole and the backflow cover, there is no problem in closing the backflow cover. Therefore, when the drainage is normally performed, the backflow cover completely shields the backflow hole.

Sixth, in the present invention, the guide step is further provided at the end of the guide plate to surround the hinge. Therefore, when the drainage is in progress, since the hinge portion of the drain cover is wrapped by the guide step, there is an advantage that the problem that foreign matter is not discharged by being caught in the hinge (hinges, etc.) of the drain cover.

Hereinafter, the configuration of a preferred embodiment of the drain guide device according to the present invention will be described with reference to the accompanying drawings.

1 to 3 show a preferred embodiment of the drain guide device according to the present invention. That is, Figure 1 and Figure 2 is an external perspective view and an exploded perspective view of the drain guide device according to the present invention, respectively, Figure 3 is a cross-sectional view taken along the line AA 'of FIG.

As shown in these figures, the drain guide device according to the present invention, the mounting plate 100 seated in the ground, sewer pipe or drainage channel, the bottom plate 110 for guiding the flow of the drainage, and the drainage of the upper side A side plate 120 that guides to the upper side of the bottom plate 110, a drain hole 130 serving as a passage through which the sewage collected to the upper side of the bottom plate 110 is drained, and the drain hole ( A drain cover 140 for selectively shielding the 130, a backflow hole 150 serving as a passage through which the sewage under the bottom plate 110 flows back to the top of the bottom plate 110, and the backflow hole 150. The reverse flow cover 160 to selectively shield, and the adhesion preventing means 170, etc. to prevent the foreign matter is attached to the upper surface of the bottom plate (110).

The mounting plate 100 has a quadrangular shape, as shown, a rectangular groove is formed inside. Therefore, the bottom plate 110 and the side plate 120 is provided in this groove.

The mounting plate 100 is installed in a drainage passage through which sewage flows, a manhole, or the like, and supports the bottom plate 110, the side plate 120, and the like. That is, the mounting plate 100 spans the edges of the grooves formed in the surface, the manhole or the sewer, and supports the bottom plate 110 to be located at the center of the groove.

The bottom plate 110 is made of a rectangular flat plate as shown, it is provided to be inclined at the lower side of the mounting plate 100. That is, the bottom plate 110 is made of a square flat plate of a smaller size than the mounting plate 100, is located at a distance separated by a predetermined distance to the lower side of the mounting plate 100, the height gradually toward the left side It is formed to be inclined so as to be low. Therefore, sewage or foreign matter on the upper side of the bottom plate 110 flows from the right side to the left side.

The side plate 120 is formed between the mounting plate 100 and the bottom plate 110 to support the bottom plate 110.

Looking specifically, the side plate 120 is formed to extend upward from the front and rear ends and the right end of the bottom plate 110. In addition, the side plate 120 is preferably formed to have an inclination. That is, the upper end of the side plate 120 is in contact with the inner end of the mounting plate 100, the side plate 120 is formed to have a predetermined inclination, the sewage flowing from the upper side of the mounting plate 100 Guide to flow into the bottom plate 110 naturally.

The drainage hole 130 is formed between the mounting plate 100 and the bottom plate 110 to allow sewage to flow.

Specifically, the guide plate 102 is further formed to be inclined at the inner left end of the mounting plate 100. The guide plate 102 is formed such that its height gradually decreases toward the right side.

In addition, a drainage hole 130 having a predetermined size is penetrated between the lower end of the guide plate 102 and the left end of the bottom plate 110. The drainage hole 130 is formed in a rectangular shape as shown, and the sewage collected above the bottom plate 110 is an entrance to the left flows.

In addition, a guide step 104 is further provided at the right end of the guide plate 102. That is, the right end of the guide plate 102 is bent downward and then extended to a predetermined length to form the guide step 104. The guide step 104 is to prevent the foreign matter is stuck to the rotary hinge portion (hinges, etc.) of the drain cover 140 to be described below. Therefore, the guide step 104 is to surround the right portion of the hinge 142 to be described below.

The drain hole 130, the drain cover 140 is opened and closed. The drain cover 140 is rotatably installed on the left side of the bottom plate 110, as shown, to open and close the drain hole (130).

An upper end of the drain cover 140 is connected to the guide plate 102 by a hinge 142 or the like. In addition, the drain cover 140 selectively shields the drain hole 130 by its own weight.

In detail, the lower half of the left end of the side plate 120 connected to the front end and the rear end of the bottom plate 110 is inclined in a '/' shape as shown. Therefore, the drain cover 140 rotatably connected to the guide plate 102 by the hinge 142 is naturally in contact with the left end of the side plate 120 by its own load. 130).

The hinge 142 serves as a hinge to allow the drain cover 140 to be coupled to the guide plate 102 and to rotate the drain cover 140. Therefore, one end is coupled to the guide plate 102, the other end is coupled to the top of the drain cover 140 by a rivet (rivet) or the like.

On the other hand, the vertical length of the drain cover 140 is formed larger than the vertical length of the drain hole 130. Therefore, the lower end of the drain cover 140 is further protruded to the lower side of the bottom plate 110. That is, as shown (see FIG. 3), the lower end of the drain cover 140 is further draped down the left end of the bottom plate 110.

The length L of which the lower end of the drain cover 140 further protrudes below the left end of the bottom plate 110 is preferably about 20 mm.

At the lower end of the drain cover 140, a bent end 144 bent to the left side is formed. That is, the lower end of the drain cover 140 is bent at a predetermined angle (to be substantially horizontal with the mounting plate) to the left, as shown, to form a bent end 144.

As described above, the lower end of the drain cover 140 to protrude about 20mm further below the bottom plate 110, and the reason for forming the bent end 144 by bending the lower end of the drain cover 140, This is to open the drain cover 140 more easily when the counter flow pressure is applied. That is, when the sewage of the lower side of the bottom plate 110 flows backward, the sewage rises from the lower side to the upper side. At this time, when the reversed sewage strikes the bent end 144, the drain cover 140 is clockwise. Rotating to the drain hole 130 is opened.

The backflow hole 150 is formed to penetrate the bottom plate 110 vertically so that the sewage below the bottom plate 110 flows back to the top of the bottom plate 110.

Looking in more detail, the right portion of the bottom plate 110, the depression 112 recessed downward is formed to a predetermined size. That is, the bottom plate 110 is formed integrally with a recessed portion 112 having a square shape recessed to a predetermined depth below.

The depression 112 is formed by pressing a portion of the bottom plate 110 with a press or the like, this depression 112 serves to reinforce the strength of the bottom plate 110 and will be described below. The backflow hole 150 serves to be spaced apart from the bottom plate 110 by a predetermined distance.

For example, if the backflow hole 150 to be described below is formed in the bottom plate 110 made of a plane, when the water flows back from the bottom plate 110, foreign matter (wood chips or metal material) is the bottom plate ( When the bottom surface collides with each other, the bottom plate 110 partially protrudes upward. Therefore, in this case, the backflow cover 160, which will be described below, may not completely shield the backflow hole 150.

Therefore, when the backflow hole 150 is formed in the bottom surface of the recess 112 as in the present invention, even if the bottom surface of the recess 112 collides with the foreign matter and protrudes upward, the bottom surface of the recess 112. Since the overflow cover 160 is spaced apart from each other, it does not affect the opening and closing of the backflow cover 160.

A plurality of backflow holes 150 penetrate upward and downward on a bottom surface of the recess 112.

The backflow cover 160 is provided on the bottom plate 110 to selectively shield the backflow hole 150. That is, the backflow cover 160 is provided above the depression 112 and is configured to selectively shield the backflow hole 150 by its elasticity.

Specifically, the backflow cover 160 may include a rectangular backflow plate 162 corresponding to the recess 112 and a fastening part extending further from the right end center of the backflow plate 162 to the right. 164 and the like. The fastening part 164 is fastened to the bottom plate 110 using a rivet or the like.

The backflow cover 160 is preferably made of an elastic panel thinner than the mounting plate 100 or the bottom plate 110. For example, when the mounting plate 100 or the bottom plate 110 is made of a metal material having a thickness of 1.0 mm to 2.0 mm, the backflow cover 160 has a thickness of about 0.2 mm to 0.3 mm. It is preferably made of a metal material.

As such, the backflow cover 160 is made of a thin metal material, and thus opens and closes the backflow hole 150 by its elasticity. That is, when the sewage pressure of the bottom plate 110 is increased, the left portion of the backflow cover 160 is lifted by the pressure of the sewage, so that the backflow cover 160 and the bottom plate 110 naturally exist. There is a gap formed in the backflow hole 150 is opened. Then, when the sewage pressure of the bottom plate 110 is lowered, the backflow cover 160 is in close contact with the bottom plate 110 by its elasticity to shield the backflow hole 150.

The adhesion preventing means 170 is formed to protrude upward from the top surface of the bottom plate 110, to prevent foreign matter from being attached to the top surface of the bottom plate 110. That is, the adhesion preventing means 170 is made of embossing (rib), ribs (rib), etc., to function to discharge the foreign matter is not attached to the bottom plate (110).

Looking in detail with reference to the drawings, the adhesion preventing means 170 is cut from the bottom plate 110 is formed to protrude upward. Accordingly, the bottom plate 110 is formed with a through hole 172 through which the adhesion preventing means 170 is cut.

In detail, the left portion of the bottom plate 110 is partially cut and protrudes roundly upwards to form the adhesion preventing means 170 (see FIG. 3). The right end of the 170 is connected to the bottom plate 110, a gap having a predetermined size is formed between the left end of the adhesion preventing means 170 and the bottom plate 110.

In addition, the distance G between the end of the adhesion preventing means 170 and the bottom plate 110 is formed to be less than 2mm. That is, as shown, the gap (G) between the left end of the adhesion preventing means 170 and the bottom plate 110 is formed to be less than 2mm. As such, the reason why the gap G between the left end of the adhesion preventing means 170 and the bottom plate 110 is formed to be less than 2 mm is because of the gap between the adhesion preventing means 170 and the bottom plate 110. G) to block the movement of insects such as mosquitoes and flies through.

Odor and release of gas also occur through the cut-out hole 172 formed in the bottom plate 110 to form the adhesion preventing means 170 as described above. That is, the odor and gas under the bottom plate 110 should be discharged through any passage, and a small amount of odor and gas is continuously discharged through the incision hole 172 and diluted in the air so that a person cannot feel it. There is an effect of preventing the backflow of odor to the residential area through the piping.

Meanwhile, the adhesion preventing means 170 may be formed on the side plate 120 in addition to the bottom plate 110. That is, since foreign matter may be attached to the side plate 120, the adhesion preventing means 170 may be formed on the side plate 120.

Hereinafter, the operation of the drainage guide apparatus according to the present invention having the above configuration will be described with reference to FIGS. 3 to 5. 4 is a cross-sectional view showing a state in which the sewage is discharged through the embodiment of the present invention, Figure 5 is a cross-sectional view showing a state in which the reverse flow through the embodiment of the present invention.

First, when sewage does not flow, it will be in the state like FIG. In this case, the backflow cover 160 shields the backflow hole 150, and the drain cover 140 blocks the drainage hole 130 by its own weight. At this time, since the incision hole 172 is open, the odor and gas in the lower side of the bottom plate 110 flows upwards little by little to prevent the phenomenon of odor flowing back to the residential area by diluting in the air. It is possible to prevent the explosion of toxic gases even when discarding lit cigarette butts.

In this state, when the sewage flows from the upper side of the mounting plate 100, it is guided by the side plate 120, it is collected by the bottom plate (110). The sewage collected by the bottom plate 110 pushes the drain cover 140, and the drain cover 140 rotates clockwise. Therefore, the sewage on the upper side of the bottom plate 110 is discharged to the left through the drainage hole 130 (see the arrow in Figure 4).

In addition, at the time of discharging the sewage, since the adhesion preventing means 170 is formed on the bottom plate 110, foreign matter is discharged together with the sewage without being attached to the bottom plate 110. In addition, since the hinge 142 is wrapped by the guide step 104, foreign matter is prevented from being caught in the gap between the guide plate 102 and the drain cover 140.

Next, we look at the case where backflow occurs.

When water in the sewer or drainage overflows due to a flood or the like, water rises upward from the lower side of the bottom plate 110.

In this case, as shown in FIG. 5, the backflow cover 160 is lifted upward by the pressure of water below the bottom plate 110, and thus the bottom plate 110 is lowered through the backflow hole 150. Drain of back flows upward.

The water below the bottom plate 110 also rotates the drain cover 140. That is, since the lower end of the drain cover 140 further protrudes toward the bottom of the bottom plate 110 and the bent end 144 is further formed, when the reverse flow pressure is applied from the lower side of the drain cover 140, the drainage The cover 140 rotates clockwise (see FIG. 5) to open the drainage hole 130. Therefore, the drain flows back toward the bottom plate 110 through the drain hole 130 (see the arrow in FIG. 5).

Of course, in this case, a small amount of water flows back toward the bottom plate 110 through the cutout hole 172 formed in the bottom plate 110.

When the drainage under the bottom plate 110 flows backward in the above state, and the reverse flow does not occur, the drain cover 140 is rotated counterclockwise by its own weight to return to the original shape. Thus, the drain hole 130 is shielded.

In addition, the backflow cover 160 is in close contact with the upper surface of the bottom plate 110 again by its elasticity, thereby blocking the flow of drainage through the backflow hole 150.

On the other hand, Figure 6 shows the configuration of another embodiment of the drain guide device according to the present invention.

In this embodiment, only the configuration of the above embodiment and the adhesion preventing means 170 is different. Therefore, hereinafter, the description of the same configuration as in the above embodiment will be omitted, and only the configuration of the adhesion preventing means 170 will be described, and the configuration having the same function as the configuration described above will be described using the same reference numerals.

As shown, the adhesion preventing means 170 is made of embossing. That is, a plurality of portions partially protrude upward from the top surface of the bottom plate 110.

Such an embossing-type adhesion preventing means 170 is formed by applying a pressure to the press or the like from below the bottom plate, so that a part of the bottom plate 110 protrudes upward. And, the adhesion preventing means 170 is made of a semi-circular shape. That is, as shown, the left side is made of straight lines and the right side is made of circles.

Therefore, a cutout hole 172 having a predetermined size is formed in a slit shape at the left end of the adhesion preventing means 170. As described above, the cutting hole 172 is formed when the adhesion preventing means 170 is formed, and the odor and gas of the lower side are discharged through the cutting hole 172.

The cutout 172 size G here is also formed to be less than 2 mm, as described above.

The scope of the present invention is not limited to the above-exemplified embodiments, and many other modifications based on the present invention will be possible to those skilled in the art within the above technical scope.

For example, the above embodiment illustrates the case where the drain cover 140 is installed on the guide plate 102, but the guide plate 102 is removed, and the drain cover 140 is mounted on the mounting plate ( It may also be configured to be installed rotatably in 100).

In addition, in the above embodiment, the backflow cover 160 has its own elasticity to shield the backflow hole 150 by the force of elasticity, but the backflow cover 160 is driven by its own load. It is also possible to shield the backflow hole 150.

In the above embodiment, the counterflow hole 150 is not formed on the same plane as the bottom plate 110, but is formed in the recess 112 recessed downward. However, it is also possible to form the backflow hole 150 as it is on the same plane as the bottom plate 110 without forming a separate recess 112.

In addition, in the above embodiment, the bottom plate 110 is illustrated to be inclined to the left side, but the bottom plate 110 may not be inclined or may be formed to be inclined in the right or other direction. The drainage hole 130 may also be formed in another direction in addition to the left side of the bottom plate 110.
