Description

Bad smell block an apparatus

The present invention relates to an odor counterflow prevention device having an opening and closing plate blocking a drain through a center of gravity and draining the rainwater and blocking odor flowing back from the sewer pipe. Equipped with the weight of the water to move the weight seam to keep the switchboard open while the stored water flows out so that the drainage smoothly without residues to maintain the best closing state of the switchboard as well as the best odor blocking function accordingly It relates to a bad smell backflow prevention device to maintain.

In general, manholes (including drains, drains, rain gutters, etc.) that are installed to discharge rainwater or sewage into sewer pipes contain odors and harmful gases generated in the sewers during summer seasons. In addition to being discharged to the outside through the reverse flow through the role of pests such as mosquitoes, in order to prevent this to install a odor blocking device to prevent backflow of odors and pests.

Odor blocking device has an opening and closing plate that automatically performs the function of draining rainwater or sewage flowing into the flow of odor backflow or pests.

That is, when rainwater or sewage flows in, it is opened by drainage water pressure, and when the water pressure is removed, it is automatically closed to block odors and backflow of pests. By self-weight of opening and closing plates such as 0384362, by weights such as Patent Registration No. 10-0807073 or Utility Model Registration No. 20-0239950-0000, by springs such as Patent Application No. 10-2002-0021413 It is divided in the way it is done.

By the way, the opening and closing method by the spring is not only complicated to add parts and manufacturing, but also has a disadvantage of frequent failures such as poor closing due to the elastic force degradation, mainly using the method made by the weight or weight of the opening and closing plate.

However, the opening / closing plate structure closed by self weight or weight is weaker than the opening / closing plate structure using spring elastic force, but it has the property of always keeping closed state by its own weight or weight of the weight, so the opening / closing plate at the inflow of sewage or rainwater It acts as a drainage resistance itself. Therefore, if a contaminant is introduced along with the inflow water, even if the water is drained, it is trapped by the opening and closing plate to accumulate and cause poor drainage. .

The present invention is a conventional problem as described above, the opening and closing plate performs a function to block the reverse flow of odor, but acts as a resistance to the drainage of water to hinder the smooth flow of water to act as an obstacle to the discharge of various foreign substances introduced with water It is a point.

In order to solve this problem, when rainwater flows in, the opening and closing plate is opened to maintain the open state for a few seconds or several minutes so that various foreign substances or contaminants introduced are washed down with the rainwater flowed in.

Therefore, an object of the present invention is to change the center of gravity of the weight of the inflow water into the opening and closing the closing plate to rotate the closing plate to maintain the open state while the stored water is drained water drainage It is to drain smoothly without resistance.

Therefore, foreign matter or contaminants introduced with the inflow water is discharged without being caught or trapped in the flow path, thereby maintaining a good state of closing the closing plate always has the ultimate purpose to improve the backflow blocking function of odor.

The configuration of the malodor backflow prevention device of the manhole of the present invention for achieving the above object,

A flow path installed at a lower portion of the cover having an inlet and an outlet to form a drain hole, and receiving and inflowing water from the drain hole;

An opening / closing plate hinged to an upper portion of an outlet of the flow path to be rotatable to open and close the outlet;

A weight which is installed on an opposite side of the opening and closing plate around the hinge portion to rotate the opening and closing plate about the hinge portion by a center of gravity to block the outlet;

The water storage unit is installed in the opening and closing plate, forming a water hole in the opening and closing plate to store the water flowing through it, and the water of the added water is moved to the center of gravity position by the weight to open the opening and closing plate. It is characterized by comprising;

In the manhole odor backflow prevention device of the present invention, when rainwater flows in, a part of the inflow water is stored in the reservoir formed in the opening and closing plate to move the center of gravity position with the weight to open the opening and closing plate, as well as the water of the storage portion. This drainage is kept open until the center of gravity is moved toward the weight, so that drainage is quickly performed without resistance during the drainage, thereby improving drainage capacity.

In addition, foreign matter or contaminants introduced with the water is discharged smoothly through the outlet without any residue is solved the problem of closing by the foreign matter that has been a problem in the meantime. As a result, after the drainage is completed, the opening and closing plate is always closed in the best condition of the outlet of the flow path, thereby improving the odor blocking function.

1 is a side cross-sectional view showing the structure of the malodor backflow prevention apparatus of the present invention, Figure 2 is a cross-sectional view of the operating state of the malodor backflow prevention apparatus of the present invention.

As shown in the drawings, the present malodor backflow prevention device 20 is installed at a lower portion of the cover 10 having a drain hole 12, and the inlet and the outlet 26 are made to have a good water flow. It constitutes a flow path 22 for receiving and receiving the inflow water from the drain hole (12). The passage 22 has an inlet portion extended to collect water flowing through the drain hole 12 of the cover 10 to be drained to the outlet 26, and a flange 24 is formed around the inlet portion. The cover 10 is to be fixed to the seating jaw 14 is seated. Of course, it may have a structure integrally coupled to the bottom of the cover (10).

In addition, the present invention malodor backflow prevention device 20 constitutes the opening and closing plate 30 in the outlet 26 of the flow path (22). The opening and closing plate 30 is hinged to the upper portion of the outlet 26, provided with a weight 50 on the opposite side of the opening and closing plate 30 around the hinge portion 40 to the weight 50 By rotating the center of the hinge portion 40 by the center of gravity by the opening and closing the outlet 26.

In particular, the opening and closing plate 30 is provided with a reservoir 32, the reservoir 32 may be configured as a reservoir 34 as shown in Figs.

The reservoir 34 is installed on the back of the opening and closing plate 30, the opening and closing plate 30 corresponding to the reservoir 34 to form a water hole 36 to a part of the inflow water flowing into the flow path (22). It is configured to flow into the reservoir. In addition, the lower portion of the reservoir 34 to form an outflow delay hole 38 so that the water flowed in and stored little by little.

In addition, the hinge portion 40 which enables the opening and closing plate 30 and the seesaw movement together with the weight 50 is configured to be biased in the opening direction of the opening and closing plate 30. That is, when a straight line (hereinafter referred to as a gravity line) is drawn in the gravity direction at the lower portion of the hinge part 40, the opening and closing plate 30 is positioned at a position away from the gravity line g. This is to maintain the open state by placing the center of gravity in the gravity line (g) as much as possible when the opening and closing plate 30 is rotated by the weight when the water is stored in the reservoir (32). This is because the maximum limit moving distance that the opening and closing plate 30 can move by the center of gravity is a gravity line g.

The weight 50 is designed to be slightly heavier than the opening and closing plate 30, the state in which the opening and closing plate 30 is rotated upward by the weight of the weight 50 is in close contact with the outlet 26 of the flow path 22. Keep it. That is, to maintain the closed state.

However, when the water level of the water tank 50 rises, the weight of the weight 50 is added to the weight of the opening and closing plate 30 so that the center of gravity is moved toward the opening and closing plate 30 so that the opening and closing plate 30 rotates. The outlet 26 is to be opened. The open state of the opening and closing plate 30 is maintained in the open state until the water stored in the reservoir 50 is discharged through the outflow delay hole 38 so that the total weight is lighter than the weight (50).

In this state, since the rainwater discharged is smoothly drained without any drainage resistance by the opening and closing plate 30, drainage efficiency is increased, and various foreign matters or contaminants introduced with the inflow water are flow paths 22 and outlets 26. ) And it is released cleanly without residue. As a result, a good closed state of the opening and closing plate 30 is ensured.

On the other hand, when the inflow of rainwater is reduced or stopped, the water in the reservoir 50 is drained through the outlet hole 54, the water level is lowered so that the center of gravity is directed toward the weight 50, the opening and closing plate 30 is the outlet It turns to 26 and closes.

When the opening and closing plate 30 blocks the outlet 26 of the passage 22, the opening and closing plate 30 is closed because the passage 22 and the outlet 26 are cleanly discharged without being caught or accumulated. Maintain a good closed state. Therefore, it can effectively block the odor flowing back from the sewer, as well as completely block backflow of the pest.

Figure 3 is a cross-sectional view showing an embodiment of the reservoir portion of the present malodor backflow prevention device.

As shown in FIG. 3, the structure of the water storage part 32 of the malodor backflow prevention device of the present invention may be configured by attaching the absorber 39 to the rear surface of the opening and closing plate 30. It is to keep the inflow water in the absorber (39).

To this end, a water hole 36 is formed on the front of the opening and closing plate 30 so that a part of the inflow water introduced therethrough is absorbed by the absorber 39.

The absorber 39 may be firmly supported by installing a separate reinforcing bar or reinforcing plate not shown in the drawing, and the water retained in the absorber 39 may be drained within a few seconds or minutes. Select and apply a material of sufficient porosity.

Figure 4 is a cross-sectional view showing another embodiment of the reservoir portion of the present malodor backflow prevention device.

According to FIG. 4 described above, the absorber 39 is formed on the front surface of the opening and closing plate 30 so that the introduced water is directly absorbed by the absorber 39.

In this way there is a structural advantage that does not need to form a separate through-hole 36 in the opening and closing plate.
