Description

{Closing and opening device of rainwater drainage area}

The present invention relates to an automatic opening and closing device for a rainwater drain, and more specifically, to shield rainwater drains installed near the edge of the road during normal times when it is not raining, and to open the top of the rainwater drain when it rains. This relates to an automatic opening and closing device for drains.

Typically, rainwater drains are installed at the edge of the road to collect rainwater.

In other words, rainwater drains are installed at the edges of paved roads where vehicles travel to drain rainwater and let it flow into sewer pipes.

These rainwater drains are covered with grating to prevent rainwater from flowing down and the wheels of cars, motorcycles, bicycles, etc., and people's feet from falling in. Rainwater drains are usually installed adjacent to the boundary stone that forms the border between the roadway and the sidewalk. do.

A typical rainwater drain is constructed by pouring concrete. At this time, a discharge pipe is connected between the lower part of the rainwater drain and the buried sewer pipe. Accordingly, rainwater that falls on the roadway and sidewalk is collected in a rainwater drain installed at the edge of the road. Afterwards, it passes through the grating and flows down to the collection space of the rainwater drain, and then flows into the sewer pipe through the discharge pipe to be drained.

However, because the sewer pipe connected to the discharge pipe of the rainwater drain is not only rainwater but also various domestic sewage, the inside of the sewer pipe is always full of bad odor, and pests such as flies caused by domestic sewage inhabit it.

Accordingly, bad odors and various pests in sewer pipes frequently spread to the outside through discharge pipes and rainwater drains, causing damage to people living nearby, including pedestrians.

Meanwhile, as mentioned above, the rainwater drain is covered with a grating that allows rainwater to pass through but prevents wheels of cars and people's feet from falling out, so the rainwater drain is always in communication with the outside.

In other words, the grating is made of metal to form a plurality of divided drain holes in a grid shape, so rainwater flows into the rainwater drain through the plurality of divided drain holes, while the wheels of cars, etc. and people's Your feet won't fall off.

However, smokers often discard cigarette butts through the plurality of divided drain holes formed in the grating, and fallen leaves and other household waste enter the rainwater drain through the drain holes, clogging the discharge pipe and sewer pipe of the rainwater drain. There was a problem that often occurred.

Likewise, if the discharge pipe and sewer pipe of the rainwater drain are clogged with cigarette butts, fallen leaves, or various household waste, rainwater cannot drain properly, and rainwater flows back through the rainwater drain, causing major problems such as flooding of roads and sidewalks. It occurs.

Accordingly, conventionally, work managers such as sanitation workers had to periodically remove the grating of the rainwater drain and then collect cigarette butts, fallen leaves, or various household waste accumulated inside the rainwater drain, thereby saving time due to unnecessary work. There was a problem with wasting money.

In addition, in order to prevent waste of time and money due to unnecessary work as described above, in normal times when it is not raining, the upper part of the grating of the rainwater drain is covered with a plate made of rubber, plastic, or metal to suppress the spread of bad odors and pests. In addition, cigarette butts, fallen leaves, and various household waste are blocked from flowing into the rainwater drain.

However, there was another problem in that the work manager had to periodically collect the plates one by one when it rained and rearrange the plates when it did not rain again, resulting in a waste of time and money.

Accordingly, the applicant of the present invention automatically closes the rainwater drain installed near the edge of the road during normal times when it is not raining, and automatically opens the upper part of the rainwater drain when it rains, thereby eliminating various odors and pests from the sewer pipe. An automatic opening and closing device for road rainwater drains that prevents this from spreading to the roadside and blocks cigarette butts, fallen leaves, and various household waste from flowing into the rainwater drain, ultimately reducing administrative costs by reducing unnecessary waste of manpower. (Patent Registration No. 10-2256569) and Rainwater Drain Opening and Closing Device (Patent Registration No. 10-2467582) were previously applied for and registered, respectively.

In both of the above two patent registrations, when it rains, the upper part of the grating of the rainwater drain is automatically opened, and when it is not raining, the upper part of the grating of the rainwater drain is automatically shielded, preventing various odors and pests from spreading from the sewer pipe to the roadside. This prevents cigarette butts, fallen leaves, and various household waste from flowing into the rainwater drain, ultimately reducing unnecessary waste of manpower, and providing useful effects such as reducing administrative costs. However, opening and closing the upper part of the grating of the rainwater drain is provided. There was a disadvantage in that the shielding plate was not properly wound around the drive shaft of the main body or could not be properly unwound from the drive shaft of the main body, preventing normal operation.

In other words, the shielding plate is made of synthetic resin, rubber, or silicone to have a flexible bonding property so that it can be wound or unwound from the drive shaft, but also has a certain rigidity. The shield plate is wound around the drive shaft to open the upper part of the grating. When opening, there was a problem in that a lifting phenomenon occurred in the laminated section and prevented proper winding, preventing smooth opening.

In particular, on the contrary, when the shielding plate is released by rotating the drive shaft to shield the upper part of the grating of the rainwater drain, the shielding plate unfolds and does not come out through the storage hole, but falls apart within the main body due to the occurrence of lifting in the laminated section. As a result, there was a problem in that smooth shielding was not achieved.

As shown in Figures 1 to 5, the automatic opening and closing device 200 of the rainwater drain 100 according to an embodiment of the present invention includes a boundary stone 20 installed on the edge of the road 10 forming the boundary between the roadway and the sidewalk. ) and can be installed at the same height and width.

Typically, the roadway and the sidewalk are bordered by boundary stones 20 having a predetermined level difference. In other words, boundary stones 20 with a predetermined height are installed at the boundary between the roadway and the sidewalk so that the sidewalk is formed as high as the height of the boundary stones 20 compared to the roadway, thereby protecting pedestrians by preventing running vehicles from encroaching on the sidewalk. do.

Therefore, a plurality of boundary stones 20 with a certain height and a certain width are arranged in a row at the boundary between the roadway and the sidewalk. The automatic opening and closing device 200 according to an embodiment of the present invention includes a plurality of boundary stones 20. A box manufactured with the same height and width as the above can be provided, and components described later can be arranged within this box.

In addition, the automatic opening and closing device 200 arranged in parallel with the boundary stone 20 includes a rainwater drain 100 formed at the edge 10 of the road, that is, a roadway, and a grating 110 covering the upper part of the rainwater drain 100. They can be placed side by side in this provided position.

The automatic opening and closing device 200 according to an embodiment of the present invention includes a main body portion 210 in which a first accommodating space 232 and a second accommodating space 234 are formed with a partition wall 230 therebetween; , It may include a case composed of a lid portion 220 that covers the upper part of the main body portion 210 and shields the first accommodating space 232 and the second accommodating space 234.

Here, since the enclosure is arranged in parallel with a plurality of boundary stones 20, it is preferable that it is made of a stone of the same material as the boundary stones 20.

A solar panel 240 is placed on the upper surface of the lid part 220 of this enclosure as a power supply unit to receive power, and the supplied power can be configured to supply the driving unit 300. Here, the driving unit 300 may be provided with a driving motor that rotates forward and backward by power supply.

For reference, in the embodiment of the present invention, it will be described as an example that the solar panel 240 is disposed on the upper surface of the lid portion 220 of the enclosure, but this is only one embodiment, and is a solar panel installed in a street light, etc. Power may be supplied to the driving unit 300, which will be described later.

In the main body 210 constituting the enclosure, a driving unit 300 and a control unit (not shown) are disposed in the first accommodation space 232, and rotate according to the driving of the driving unit 300 in the second accommodation space 234. The drive shaft 310 and the shield plate 320 that are wound or unwound by the forward and reverse rotation of the drive shaft 310 may be disposed.

Accordingly, a storage hole 212 in the form of a long hole for storing the shielding plate 320 may be formed on one side of the main body 210 constituting the enclosure according to the forward and reverse rotation of the drive shaft 310.

For reference, the shielding plate 320 may be made of a synthetic resin material, rubber material, or silicone material to have a certain elasticity and a certain strength and hardness.

In addition, a plurality of guide plates 500 and a plurality of pressure elastic members 600 may be installed at regular intervals in the second receiving space 234 of the main body portion 210 constituting the enclosure. These guide plates The detailed configuration and operational relationship between 500 and the pressure elastic member 600 will be described in detail later.

Meanwhile, a rain detection unit (not shown) for detecting rainwater may be installed inside the second receiving space 234 of the main body 210, and its operating relationship will also be described in detail later.

The plurality of guide plates 500 installed at regular intervals in the second accommodation space 234 of the main body 210 have edges welded to the inner wall of the second accommodation space 234 of the main body 210. It is made in the shape of a plate fixed with a receiving hole 510 having a relatively larger diameter than the overall diameter when the drive shaft 310 is wrapped around the shielding plate 320, and the central portion is formed, and the main body 210 A cutout 520 may be formed on one lower side adjacent to the storage hole 212 of a height that allows the shielding plate 320 to pass through.

Here, the receiving hole 510 and the cutout 520 are configured to communicate with each other, and thus the shielding plate 320 wound around the drive shaft 310 passes through the receiving hole 212 through the cutout 520. The shielding plate 320, which is pulled out to cover the upper part of the grating 110 or covers the upper part of the grating 110, can be wrapped around the drive shaft 310 while passing through the storage hole 212 and the cutout 520. .

At this time, as described above, the shielding plate 320 has a predetermined strength and hardness, but is made of synthetic resin, rubber, or silicone with elasticity, so it can be wound or unwound by the forward and reverse rotation of the drive shaft 310. When doing so, it may not be wound or unwound properly due to the occurrence of lifting in the laminated section.

In particular, when the shielding plate 320 is released by rotation of the drive shaft 310, cases in which the shield plate 320 is not properly pulled out through the storage hole 212 due to the phenomenon of lifting due to lifting may occur more frequently.

However, in an embodiment of the present invention, the surrounding surface of the receiving hole 510 of the guide plate 500 serves as a guide when winding or unwinding the shield plate 320 and simultaneously suppresses the occurrence of lifting in the lamination section, so that the drive shaft 310 ), when the shielding plate 320 is unwound and pulled out or wound and pulled in according to the forward and reverse rotation, a smooth winding and unwinding action can be achieved.

Accordingly, the shielding plate 320 is properly wound around the drive shaft 310 or properly unwound to accurately shield the rainwater drain 100, thereby reducing administrative costs due to maintenance and preventing clogging of the rainwater drain 100. Alternatively, the effect of more effectively preventing occurrence of odor, etc. may be provided.

Meanwhile, the pressing elastic member 600 includes a round-shaped tension part 610 for elastically pressing the upper region of the shielding plate 320 wound around the drive shaft 310, and both ends of the tension part 610. It may be configured to include a pair of fixing parts 620 that are bent and at least one of which is fixedly coupled to the inner wall surface of the second receiving space 234 of the main body 210.

Here, of the pair of fixing parts 620, at least one is fixedly coupled to the inner wall surface of the second receiving space 234 of the main body 210, and the other is not fixedly coupled to the tension part 610. By having a gap at a certain distance in the vertical direction, the shield plate 320 can be configured to elastically press the upper part in a state in which the shield plate 320 is wound or released from the driving unit 300.

Such a pressing elastic member 600 may be installed to be disposed between the guide plates 500, and accordingly, when the drive unit 300 rotates forward and backward to wind or unwind the shielding plate 320, the shielding plate 320 ) By pressurizing the upper area by elasticity, it is possible to wind or unwind more effectively.

That is, when the shielding plate 320 is released, the upper area of the shielding plate 320 is pressed to prevent lifting of the drive shaft 310, so that the shielding plate 320 is inserted into the receiving hole of the guide plate 500. 510) It moves along the perimeter to ensure smooth unwinding, and conversely, even when winding the shield plate 320, the upper area of the shield plate 320 is pressed to prevent lifting of the laminated section of the shield plate 320. This can ensure smooth winding of the shielding plate 320.

Figure 6 is an exploded perspective view of an automatic opening and closing device according to another embodiment of the present invention, Figure 7a is a perspective view of the guide plate in Figure 6, and Figure 7b is a rear perspective view of Figure 7a.

In addition, Figure 8a is a cross-sectional view of the automatic opening and closing device according to another embodiment of the present invention with the upper part of the grating open, and Figure 8b is a cross-sectional view of the upper part of the grating in a shielded state in Figure 8a.

In describing an automatic opening and closing device according to another embodiment of the present invention, the same parts as those in the previously described embodiment will be described by assigning the same reference numerals, and repeated descriptions will be omitted.

As shown in FIGS. 6 to 8, compared to the previous embodiment, the automatic opening and closing device 200 according to an embodiment of the present invention excludes the configuration of the pressing elastic member 600 and has a guide plate 500. ) A plurality of bearing members 540 may be installed at regular intervals around the receiving hole 510.

At this time, fastening holes 530 are formed at regular intervals around the receiving hole 510 of the guide plate 500, and the bearing member 540 includes a bolt 542 and a nut penetrating the fastening hole 530. It can be installed rotatably with respect to the guide plate 500 by fastening (544).

In a state where the bearing member 540 is rotatably coupled to the guide plate 500 using bolts 542 and nuts 544, a portion of the bearing member 540 is positioned in the receiving hole 510. It is desirable to do so.

At this time, the gap between the portion of the bearing member 540 located in the receiving hole 510 is smaller than the gap between the outer diameter of the drive shaft 510 and the inner diameter of the receiving hole 510 of the guide plate 500. It is desirable.

The reason is that the bearing member 540 presses only the shielding plate 320 that is wound or unwound around the drive shaft 310 and rotates in conjunction with it in the rotation direction to guide the winding or unwinding.

For reference, in the drawing to support the automatic opening and closing device according to another embodiment of the present invention, it is shown as an example that the bearing member 540 is rotatably installed only on one side of the guide plate 500, but it is limited to this. This is not the case, and the bearing member 540 may be installed symmetrically on both sides of the guide plate 500.

Meanwhile, the guide plate 500 may be formed in a state in which both lower side ends of the guide plate 500 are spread out in a direction that intersects at a predetermined distance based on the same horizontal line.

In this way, when both lower end ends of the guide plate 500 are formed in a direction that intersects at a certain interval based on the same horizontal line, the inner diameter of the receiving hole 510 becomes spiral, so that the drive shaft 310 The shielding plate 320 can be wound or unwound more flexibly.

Of course, this configuration of the guide plate 500 is not only applied to other embodiments, but can also be applied equally to the previous embodiments.

The operating relationship of the automatic opening and closing device 200 for a rainwater drain according to an embodiment of the present invention, which can be configured as described above, will be described with reference to FIGS. 1 to 9 as follows.

Figure 9 is a flowchart showing the control relationship of the automatic opening and closing device 200 according to an embodiment of the present invention.

First, as shown in Figures 1 and 2, a rainwater drain 100 is formed in the area of the edge 10 of the road forming the boundary between the roadway and the sidewalk, and a grating 110 is placed on the top of the rainwater drain 100. In this installed state, a box having the same height and same width as the boundary stone 20 is arranged in parallel with the plurality of boundary stones 20 at a position adjacent to the grating 110.

In this state, when the rain detection unit disposed in the main body 210 of the enclosure detects that it is not raining more than the set precipitation amount (S10), the rain detection unit transmits its signal to the control unit, and the control unit receives the rain from the rain detection unit. An operating signal is applied to the driver 300 according to the received signal.

Accordingly, the driving unit 300 rotates the driving shaft 310 by reverse rotation (S40), and as a result, the shielding plate 320 slides through the storage hole 212 formed in the main body 210 forming the enclosure, forming a grating. (110) The upper part is covered (S50).

At this time, the shielding plate 320 wound around the drive shaft 310 is guided in the direction of withdrawal according to the release by the pressure elastic member 600 or the bearing member 540 and the guide plate 500, thereby preventing the drive shaft from being caught in the rack. The withdrawal is carried out smoothly without any error in (310), and since this has been explained previously, repeated explanations regarding this will be omitted.

In this way, when the grating 110 of the rainwater drain 100 is covered with the shielding plate 320, the drain holes 112 of the grating 110 are blocked from the outside, through which cigarette butts, fallen leaves, or various Not only can the inflow of household waste be blocked, but it can also prevent odors and various pests from spreading to the ground through sewer pipes.

Meanwhile, with the rainwater drain 100 and the grating 110 covered by the shielding plate 320, if it rains more than the set amount, the rain detection unit detects this (S10) and transmits a signal to the control unit. An operating signal is applied to the driving unit 300 by the signal received from the sensing unit.

That is, when it rains more than the set amount, the falling rain flows into the second receiving space 234 of the main body 210 through the storage hole 212 of the enclosure along the upper surface of the shielding grating 110. , The rain detection unit that can be placed in the second receiving space 234 can detect rain through it, and the signal detected in this way is transmitted to the control unit.

Therefore, the control unit rotates the drive shaft 310 as it applies a rotation (S20) signal to the drive unit 300, and accordingly, the storage hole 212 formed in the main body 210 forming the enclosure with the shield plate 320 As it slides through and is wound around the drive shaft 310, the rainwater drain 100 and the grating 110 are opened to be exposed to the outside (S30).

At this time, the shielding plate 320 is guided in the direction of retraction according to the winding by the pressurizing elastic member 600 or the bearing member 540 and the guide plate 500, so that the shield plate 320 is smoothly moved without the drive shaft 310 being loose due to the rack being caught. Winding and insertion are carried out, and since this was explained previously, repeated explanations for this will be omitted.

In this way, when the rainwater drain 100 and the grating 110 are opened, the rainwater falling on the roadway and sidewalk collects in the area of the road edge 10, and then the rainwater flows through the drain holes 112 and 112 of the grating 110. After passing through the drainage space of the drain 100, drainage occurs through the discharge pipe and sewer pipe.

As described above, according to the automatic opening and closing device 200 of the rainwater drain 100 according to an embodiment of the present invention, the shielding plate 320 is installed on the drive shaft 310 according to forward and reverse rotation of the drive shaft 310 by a control signal. ) is wound smoothly, so that the upper part of the grating 110 of the rainwater drain 100 is clearly opened, and the shielding plate 320 is smoothly released from the drive shaft 310, so that the grating of the rainwater drain 100 ( 110) By reliably shielding the upper part, deterioration of the opening and closing performance of the rainwater drain 100 due to malfunction can be prevented, ultimately providing the effect of improving product satisfaction.

In addition, according to the automatic opening and closing device 200 of the rainwater drain 100 according to an embodiment of the present invention, the shielding plate 320 is properly wound on or properly released from the drive shaft 310 without malfunction due to a simple configuration. By accurately shielding or opening the rainwater drain 100, waste of administrative costs due to maintenance can be reduced, and clogging or foul odors in the rainwater drain 100 can be prevented more effectively.

Those skilled in the art to which the present invention pertains will understand that the present invention can be implemented in other specific forms without changing its technical idea or essential features. Therefore, the embodiments described above should be understood in all respects as illustrative and not restrictive. The scope of the present invention is indicated by the claims described below rather than the detailed description above, and all changes or modified forms derived from the meaning and scope of the claims and their equivalent concepts should be construed as being included in the scope of the present invention. do.
