Hereinafter, preferred embodiments of the apparatus for preventing rainwater inflow will be described in detail with reference to the accompanying drawings.

1 is an exploded perspective view showing an apparatus for preventing rainwater inflow according to a first embodiment of the present invention, and FIG. 2 is a plan view showing a rainwater blocking structure when rainwater is introduced in the first embodiment.

Rainwater inflow prevention device according to this embodiment is for preventing rainwater from entering into a structure such as an underground house, an underground shopping mall, a factory, etc., a prop 10, a mounting space 20, a guide projection 30, It includes a buoyancy body 40, a support film 50, a water blocking portion 60, an angle 70, and a seal sheet 80.

The posts 10 are spaced apart at regular intervals at the entrance of the structure. A wall (W) may be connected to the support (10), and the wall (W) is built to a certain height so that the inflow of rainwater is blocked. Between the holdings 10, it is opened for the passage of people or bringing in and taking out objects, so rainwater or the like may flow between the holdings 10 due to heavy rain or flooding.

The mounting space 20 is a buoyancy body 40 installed therein to be able to elevate, and is formed by digging the front bottom surface F of the outside of the structure, that is, the pillar 10. The floor surface on which the mounting space 20 is formed may be formed of a concrete floor or a soil floor. A drain line 21 for draining a portion of rainwater flowing into the mounting space 20 is formed under the mounting space 20. The drain line 21 can control the amount of water when an excessive amount of water flows into the mounting space 20, and the water remaining in the mounting space 20 is also efficient so that the buoyancy body 40 does not interfere with the descent. Can drain.

The guide projections 30 are formed on both sides of the inside of the mounting space 20 up and down, respectively, to guide the lifting of the buoyancy body 40. Due to the guide projection 30, the buoyancy body 40 can be smoothly elevated without shaking.

The buoyancy body 40 is installed so as to be able to elevate in the mounting space 20 and rises by buoyancy when water flows into the mounting space 20. As the material of the buoyancy body 40, a light material having a specific gravity smaller than water may be used, for example, synthetic resin or styrofoam. On both side surfaces of the buoyancy body 40, guide guides 30 are formed with grooves into which the guide protrusions 30 are slidably inserted, respectively. Since the length of the guide 41 is formed higher than the height of the buoyancy body 40, it is also possible that the buoyancy body 40 rises to the top of the floor F in some cases.

The support film 50 elastically supports the buoyancy body 40 with respect to the floor surface inside the mounting space 20. The support film 50 has an elastic force on itself, and is normally pressed by the self-weight of the buoyancy body 40 while descending to maintain the state in which the buoyancy body 40 descends, and water flows into the mounting space 20 When the buoyancy occurs, since the load acting from the buoyancy body 40 is reduced, the supporting film 50 rises together with the buoyancy body 40 to maintain the buoyancy body 40 in an elevated state. A rubber plate may be used as the support film 50. On the other hand, the support film 50 serves as a shielding film covering the spaces between the pillars 10 when the buoyancy body 40 rises to the top of the bottom surface F, between the pillars 10 together with the buoyancy body 40. By blocking the space, the water flowing between the pillars 10 is blocked.

The water blocking part 60 is provided on the rear surface of the buoyancy body 40 to block the space between the support body 10 together with the buoyancy body 40 when the buoyancy body 40 rises, so that rainwater from the outside is held (10). ) To prevent them from entering. That is, when the buoyancy body 40 rises, the water blocking portion 60 is in contact with the front portion of the angle 70 to block the inflow of water through between the buoyancy body 40 and the support 10. The water blocking part 60 may be formed to extend from the support film 50 as shown in the drawing or may be formed separately.

The angle 70 is installed on the front surface of the post 10 to block the inflow of water between the post 10 and the buoyancy body 40. When the buoyancy body 40 rises on both sides of the water blocking portion 60, it is in close contact with the angle 70, thereby completely blocking the inflow of water by removing the gap between the support 10 and the buoyancy body 40 together with the angle 70 Do it.

3 is a perspective view showing a state where the buoyancy body is normally lowered in the first embodiment, and FIG. 4 is a longitudinal sectional view of FIG. 3.

Normally or when the amount of water flowing into the structure is small, there is no or little water flowing into the mounting space 20, so that the buoyancy that the buoyancy body 40 can rise is not formed. Therefore, the supporting film 50 is pressed by the weight of the buoyancy body 40 while the buoyancy body 40 maintains a descending state.

When a small amount of water is introduced into the structure, the water does not pass between the pillars 10 and flows into the entire mounting space 20 and is then drained out through the drain line 21. Therefore, it does not flow into the structure through the posts (10).

On the other hand, the buoyancy body 40 is supported in a descending state by the support film 50, but its top surface is coincident with the bottom surface (F), so that it does not interfere with the passage of people or the entry and exit of objects at all. When the buoyancy body 40 is lowered, the load of the buoyancy body 40 and the elasticity coefficient of the support film 50 are determined so that the top surface of the buoyancy body 40 coincides with the bottom surface F.

A pin-shaped guide member 43 may be provided on the bottom surface of the buoyancy body 40 to easily press the support film 50 when the buoyancy body 40 descends.

5 is a perspective view showing a state in which the buoyancy body rises when rainwater flows in the first embodiment, and FIG. 6 is a longitudinal sectional view of FIG. 5.

In the case of heavy rain or flood, when a large amount of water approaches the structure, water flows into the mounting space 20 formed on the front bottom surface F of the strut 10 before passing between the struts 10. Of course, a small amount of water in the initial flow of water may pass between the pillars 10.

When water flows into the mounting space 20, buoyancy is generated in the buoyancy body 40, and the buoyancy body 40 is automatically raised by the buoyancy. Since the rising height of the buoyancy body 40 is determined according to the amount of water flowing into the mounting space 20, when a large amount of water is introduced, the rising height of the buoyancy body 40 is increased.

Since the buoyancy body 40 rises and blocks the space between the two pillars 10 together with the water blocking portion 60, it is possible to primarily block the inflow of a large amount of water between the pillars 10.

With the rise of the water blocking portion 60, the water blocking portion 60 is in contact with the front portion of the angle 70, and the seal sheet 80 provided in the water blocking portion 60 is in close contact with the angle 70, so that the holding ( 10) and the water flowing between the buoyancy body 40 can be secondaryly blocked.

As described above, it is made to primarily block a large amount of water through the water blocking unit 60 and to block the water secondaryly through the water blocking unit 60, the angle 70, and the seal sheet 80, thereby forming a structure. Access water can be completely blocked.

On the other hand, as shown in the drawing, when the buoyancy body 40 rises to the upper side of the bottom surface F, the support membrane 50 together with the buoyancy body 40 also blocks the space between the props 10, thereby holding the spaces between the props 10. It blocks the inflow of water through.

When a large amount of water is continuously introduced into the mounting space 20, even if a part of the introduced water is drained through the drain line 21, more than a certain amount of water is continuously filled into the mounting space 20, so that the buoyancy body 40 The ascended state is maintained. If, in the event of heavy rain or flooding, the inflow of water into the mounting space 20 is reduced or stopped, the water flowing into the mounting space 20 is drained to the outside through the drain line 21 so that the buoyancy disappears and the buoyancy body 40 is lowered.

7 is a longitudinal sectional view showing a rainwater inflow prevention device according to a second embodiment of the present invention.

According to the rainwater inflow prevention device according to the present embodiment, a height adjusting means capable of manually adjusting the height of the buoyancy body 40 may be further provided. Other components are the same as in the first embodiment, so a description thereof will be omitted.

The height adjusting means is a plurality of height adjusting grooves 42 spaced apart vertically on the front surface of the buoyancy body 40, one end is removably fitted into the height adjusting groove 42, and the other end is a bottom surface ( F) includes a height adjustment bar 90 that spans.

By using such a structure, the user manually raises the buoyancy body 40 before the heavy rain or flood occurs, and then inserts the height adjustment bar 90 into the height adjustment groove 42, thereby buoyancy body 40. Can increase the height of.

Since one end of the height adjustment bar 90 is fitted in the height adjustment groove 42, the other end of the height adjustment bar 90 spans the ground, so that the buoyancy body 40 does not descend and maintains an elevated state.

8 is a perspective view showing a rainwater inflow prevention device according to a third embodiment of the present invention, FIG. 9 is a cross-sectional view showing a state in which the buoyancy body is normally lowered in the third embodiment, and FIG. 10 is rainwater inflow in the third embodiment It is a cross-sectional view showing a state in which the buoyancy body rises.

The apparatus for preventing rainwater inflow according to the present embodiment further includes a water inflow expansion space 100, a water inflow lid 110, and a dirt filter 120 in the first embodiment. The rest of the components are the same as in the first embodiment, so a description thereof will be omitted.

The water inflow expansion space 100 is formed by digging the front bottom surface of the mounting space 20 to expand the water inflow area so that a large amount of water can be introduced into the mounting space 20 in a short time. The lower portion of the water inflow expansion space 100 is connected to the mounting space 20.

The water inlet lid 110 is installed to be detachable at the entrance of the water inflow expansion space 100 so that a person or object does not fall into the water inflow expansion space 100 when a person passes or wants to carry objects in and out of the structure. Filter out large filth. A plurality of water inlet holes 111 through which water passes is formed in the water inlet lid 110. The top surface of the water inlet cap 110 is aligned with the ground so that it is not caught when a person passes. In order to remove the filth filtered by the filth filter member 120 located in the water inflow expansion space 100, the water inflow cap 110 may be separated from the water inflow expansion space 100.

The dirt filter member 120 is installed below the water inflow lid 110 in the water inflow expansion space 100 to filter out the dirt flowing through the water inflow lid 110. In addition to the case where only filth is introduced, even if filth is introduced together with water, filth can be effectively filtered. When the amount of dirt filtered by the dirt filter member 120 is large, the dirt may be removed after removing the water inlet lid 110 as described above. The filth filter member 120 is formed separately from the water inflow lid 110 and installed in the water inflow expansion space 100, but is not limited thereto, and the water inflow expansion space in a state coupled to the water inflow lid 110 ( 100).

9 and 10, the water inflow area is expanded due to the water inflow expansion space 100. Accordingly, when a large amount of water is pushed into the structure, a large amount of water is introduced into the mounting space 20 through the water inflow expansion space 100 as well as the inlet of the mounting space 20, so that the buoyancy of the buoyancy body 40 in a short time Since this occurs, the buoyancy body 40 can be automatically raised in a short time.
