Description

Rainwater collecting apparatus with initial rainwater exclusion device using IoT}

The present invention relates to a rainwater collection device, and more particularly, to a rainwater collection device equipped with an initial rainwater exclusion device using the Internet of Things that can automatically block the initial rainwater at the start of rainfall and collect only good-quality rainwater. .

Today, environmental pollution that is getting worse and water shortage due to the depletion of groundwater is emerging as a global issue. In particular, in the case of Korea, due to the high pavement rate of roads, a significant amount of rain does not penetrate underground and flows down the surface to rivers or seas and is not utilized. The problem of water shortage is even more serious due to the nature of the environment, which is characterized by severe drought in spring.

As a countermeasure against this water shortage, various methods and policies have been proposed, such as a gray water system that reuses used water or a rainwater storage facility. However, heavy water systems and rainwater storage facilities are basically costly to install, and especially rainwater storage facilities are very large. is virtually impossible to install. In order to apply the gray water system to an existing building, the building needs to be remodeled, so it is applied only to new buildings.

Meanwhile, in recent years, various small-scale rainwater recycling facilities have been proposed to maximize the economic value of rainwater that is not utilized and is discarded. These facilities include, for example, those that collect rainwater that falls on the roof into a cistern and use it for cleaning, landscaping or firefighting when necessary.

However, in most of the conventional rainwater recycling facilities, the problem of fine pollutants mixed in the initial rainwater is not considered. Initial rainwater refers to rainwater that has fallen for 30 minutes immediately after the start of rainfall or rainwater that has filled 5mm of rainfall after the start of rainfall.

As is known, the initial rainwater is mixed with fine dust or various pollutants in the atmosphere, and when it falls on the roof or glass window, it is inevitably in contact with pollutants such as dust or heavy metals accumulated on the roof or glass window. They are mixed with substances and should only be used after contamination treatment.

As one of the rainwater recycling systems for solving the above problems, Korean Patent No. 10-0908095 (rainwater recycling system for buildings) has been disclosed. The rainwater recycling system includes a water collecting tank for precipitating rainwater flowing down from the roof, a storage tank and treatment tank for receiving and storing and purifying rainwater after sedimentation in the water collecting tank, a mixing tank for mixing active ions in the treatment tank, and a plurality of of pumps, etc.

However, the stormwater recycling system has problems such as a complex structure and a very large number of processes for treating pollutants, as well as requiring a lot of power to use a pump or the like.

Hereinafter, one embodiment according to the present invention will be described in more detail with reference to the accompanying drawings.

1 is a view showing the overall structure of a rainwater collection device 20 having an initial rainwater exclusion device using the Internet of Things according to an embodiment of the present invention, and FIG. 2 is a block for explaining the operation principle of the rainwater collection device. It is also

As shown, the water collecting device 20 according to the present embodiment includes an initial rainwater drainer 25, a filter 33, a rainwater tank 41, upper and lower signal generators 43 and 45, and a water supply pipe 49. , a controller 47 is provided.

The initial rainwater drainer 25 serves to block the movement of the initial rainwater at the start of the rain to the rainwater tank 41 . As mentioned above, since the initial rainwater contains various contaminants, the inflow of the initial rainwater is blocked.

The initial rainwater drainer 25 has a receiving tube 21 , an inlet pipe 23 , a receiving chamber 25a , a drain pipe 25b , an accumulating flowmeter 25c , and a shutoff valve 25d .

The trough 21 is located at the lower end of the eaves of the roof 11 and receives rainwater flowing down the slope of the roof 11 and sends it down to the introduction pipe 23 . A screen mesh 22 is mounted on the receiving container 21 . The screen network 22 serves to filter out foreign substances such as leaves. Rainwater flowing into the receiving chamber 25a through the introduction pipe 23 goes down to the drain pipe 25b, moves to the first guide pipe 31, or falls into the overflow pipe 27 . Rainwater drained to the drain pipe (25b) is discarded.

The first induction pipe 31 is a pipe connecting the receiving chamber 25a and the filter 33 and is opened and closed by the induction valve 32 . The induction valve 32 is controlled by a controller 47 .

Rainwater flowing into the receiving chamber (25a) is discharged to the drain pipe (25b) when the induction valve (32) is closed, and discharged to the first induction pipe (31) when the shut-off valve (25d) is closed. In addition, when both the induction valve 32 and the shut-off valve 25d are closed, they fall into the overflow pipe 27 .

The integrated flow meter 25c is mounted on the drain pipe 25b and serves to measure the flow rate of rainwater passing through the drain pipe 25b. In other words, it measures the total flow of rainwater that has passed through it. The measurement information of the integrating flow meter 25c is transmitted to the controller 47 and the shut-off valve 25d.

In addition, the shut-off valve 25d blocks the drain pipe 25b after the initial rainwater is drained based on the measurement information of the integrated flow meter 25c. The shut-off valve (25d) is opened only until the initial rainwater is drained, and is closed after the initial rainwater is drained. The operation of the shut-off valve 25d is performed by the controller 47, and depending on the type of the shut-off valve, the shut-off valve 25d may operate by itself in conjunction with the integrating flow meter 25c.

The initial rainwater is rainwater corresponding to the flow rate of the volume multiplied by 5mm by the vertical projected area of the slope of the roof 11 . For example, if the vertical projection area of the slope is 100 square meters, the initial rainfall is 0.5 m ³ . The shut-off valve (25d) is ^{shut off as soon as the integrating flowmeter (25c) measures 0.5m 3} so that no more rainwater is thrown away.

The induction valve 32 is opened at the same time as the shut-off valve 25d is shut off. As the induction valve 32 is opened, rainwater that is additionally introduced into the receiving chamber 25a moves downward through the first induction pipe 31 and passes through the filter 33 . The filter 33 serves to treat contaminants and microorganisms contained in rainwater. Although most contaminants and impurities have been removed through the discharge of the initial rainwater, contaminants, microorganisms and impurities that may remain are filtered out. As long as it can perform these functions, the type of filter can be different.

Rainwater passing through the filter 33 flows into the rainwater tank 41 through the second guide pipe 35 . The rainwater tank 41 is composed of a tank body 41a and a lid 41b opened upward, and has a plurality of light transmitting windows 41c on the side of the tank body 41a. The level of rainwater can be visually checked through the light-transmitting window 41c. In addition, a use valve 67 is installed at the lower end of the tank body 41a. The use valve 67 can be used to drain rainwater. The use valve 67 has a structure like a faucet.

In addition, an upper signal generator 43 and a lower signal generator 45 are provided inside the tank body 41a. The upper signal generator 43 and the lower signal generator 45 are vertically spaced apart from each other up and down.

The upper signal generator 43 determines the maximum level of rainwater, and the lower signal generator 45 determines the minimum level of rainwater. That is, when the level of rainwater flowing in through the second guiding pipe 35 exceeds the upper signal generator 43 , the upper signal generator 43 outputs a signal and sends it to the controller 47 , and the controller 47 induces to shut off the valve 32 .

The organic control of the water collection device using the controller 47 as described above is one of the control methods of the general Internet of Things system. That is, the controller is connected to the shut-off valve 25d, the induction valve 32, the upper and lower signal generators 43 and 45, the constant valve 49a, and the accumulating flow meter 25c through the Internet to collect information and collect information. based on control and management.

Also, when the water level is lower than the lower signal generator 45, the lower signal generator 45 outputs a signal so that the controller 47 opens the constant valve 49a to supply constant water to the tank body 41a.

In order to perform these functions, the upper and lower signal generators 43 and 45 are connected to the controller 47 in a wired or wireless manner. The controller 47 receives the signals generated from the upper and lower signal generators 43 and 45 to operate the induction valve 32 and the constant valve 49a.

The operation of the rainwater collection device 20 having the above configuration is performed as follows. When the rain starts, rainwater flows down the slope of the roof 11 and enters the gutter 21 . At this time, bulky foreign substances such as fallen leaves are filtered by the screen network 22 . At this time, the shut-off valve 25d is open, and the induction valve 32 is in a closed state.

Rainwater flowing into the receiving trough 21 flows to the lower part and is measured while passing through the accumulating flow meter 25c and then drained through the shut-off valve 25d. If rainwater of a flow rate corresponding to the initial rainwater has passed by the integrating flowmeter 25c, the controller 47 opens the induction valve 32 and closes the shutoff valve 25d. The shut-off valve 25d may be opened and closed by itself depending on the type.

After the induction valve 32 is opened, rainwater inside the receiving chamber 25a is filled in the rainwater tank 41 through the first guide pipe 31 , the filter 33 , and the second guide pipe 35 . When the level of rainwater filled in the tank body 41a gradually rises and finally exceeds the upper signal generator 43 , the controller 47 blocks the induction valve 32 .

By blocking the induction valve 32, the inflow of rainwater into the rainwater tank 41 is stopped, and the water level in the receiving chamber 25a rises. When the water level of the receiving chamber 25a continues to rise and reaches the full water level, rainwater is discharged through the overflow pipe 27 and discharged through the drain pipe 25b.

On the other hand, for example, during dry season, the water level inside the rainwater tank 41 is gradually lowered, and finally, when the water level of the rainwater falls to a lower level than the lower signal generator 45, the controller 47 controls the lower signal generator 45 of the Upon receiving the signal, the constant valve 49a is opened. By opening the water supply valve (49a), tap water is filled in the rainwater tank (41).
