Description

A FOLDING FLOW CONTROL DEVICE

The present invention relates to a folding type flow rate adjusting device, and more particularly, to a folding type flow rate adjusting device that can easily access main parts through a circular manhole inlet having a small diameter and can assemble major parts in a manhole in a short time, The present invention relates to a folding type flow rate regulating device for exposing a lever of an opening regulating means to an upper portion of a water diaphragm plate so that an opening degree of a plate can be easily set.

Normally, a manhole is a hole that can be opened and closed by a person to inspect, repair or clean water pipes, sewage pipes, wiring, etc.

In particular, the manhole is installed mainly on the roads of the city center to prevent harming the beauty of the city center.

These manholes are connected to the bottom surface of household wastewater generated from households, factory wastewater from factories or workplaces, connection pipes for inducing and discharging the initial rainwater collected through the drainage line of the roads to the sub-collector, A drain pipe is connected.

However, when the conventional manhole is exposed to rain, it is discharged through the connection pipe through the connection pipe and the sewage treatment cost of the sewage water treatment plant is increased unless the secondary pipe and the connection pipe are refluxed.

In order to achieve this, it is desired to provide an opening / closing plate which is opened or closed according to the amount of water in the existing manhole. However, since the manhole cover installed in the manhole has a standardized size, the upper concrete of the manhole has to be crushed.

However, most of the manholes are installed on the roads, which causes traffic congestion on the roads, and also has a problem of costly manhole damage.

The above-mentioned problem can be solved by "Manhole Excellence and Soil Entrainment Prevention Apparatus (Patent Registration No. 1296566)".

Such a conventional manhole excellent soil and soil inflow preventing device is constructed such that the main parts mentioned above are separated into equal parts because the opening and closing plate, the frame, and the rotating shaft can not enter into the manhole, and then reassembled inside the manhole.

This is because the number of major parts increases in a very narrow manhole, which is very difficult to assemble, and the installation time is increased, which causes a rise in labor costs.

In addition, when the opening degree of the opening / closing plate is adjusted, since the position of the weight is adjusted after the opening / closing plate is separated, there is a problem that it takes a long time.

The diameter of the manhole cover 200 and the manhole cover 220 is usually 50 to 60 cm and the size of the frame 10a having an average width of 1 m or more is larger than the size of the manhole entrance 200.

As shown in FIG. 5, the frame frame 10a has a first folding portion 13a so as to enter the inside of the manhole 200 without being separated from each other.

The first folding portion 13a is configured to be connected to the vertical frame 12a of the frame frame 10a through a hinge H so that when the frame portion 10a flows in and out of the manhole entrance 200, .

As shown in FIG. 4, the main frame 10b is a frame in which the open / close board 30 is installed, and one lateral frame 11b is hinged to the frame frame 10a to be opened.

At this time, the other side horizontal frame 11b of the main frame 10b is formed with a handle 14b so as to grasp the handle 14b by hand and to open the main frame 10b upward.

The above-described configuration is advantageous in that, by opening the main frame 10b, people or dredging equipment can be introduced into the lower portion of the open / close board 30 without separating the open / close board 30 or the bolt shafts 34 The center of gravity of the opening / closing plate 30 can be easily adjusted through the nut 35 fastened to the opening / closing plate 30.

As shown in FIG. 6, the main frame 10b is configured to be able to enter the inside of the manhole 200 by forming the second folding portion 13b in the vertical frame 12b so as to be folded in the opposite direction of opening .

The horizontal retention stopper 20 is coupled to one side transverse frame 11b of the main frame 10b to intercept the closing of the opening and closing board 30 to maintain the horizontal state of the opening and closing board 30. [

The flow control plate 21 is superimposed on the upper surface of the horizontal holding stopper 20 and selectively adjusts the water inflow amount through the front / rear position adjustment.

The opening and closing plate 30 is coupled to a rotating shaft which is formed in the main frame 10b and the first water film plate 31 is integrally bent upward.

A plurality of bolt shafts 34 are coupled to one side of the bottom surface of the opening and closing plate 30 so as to maintain the normally opened state and the weight can be increased or decreased according to whether the nuts 35 are fastened or not. city)

In addition, the second water dam plate 22 is coupled to both sides of the flow control plate 21 and formed at a height relatively larger than the first water dam plate 31.

The second water dam plate (22) is arranged in the inner direction of the first water dam plate (31).

As shown in FIG. 7, the opening / closing plate 30 has a third folding portion 32 so that the central region can be folded in half so as to easily enter the manhole entrance 200.

The third folding part 32 is also connected to the hinge H and is folded downward through the third folding part 32 so as to avoid the interference of the first water filming plate 31. [

8, the opening regulating means 40 includes an opening / closing plate 30 coupled to an upper end of the second water dam plate 22 and lowered about a rotation axis, 44 to adjust the degree of opening of the opening and closing plate 30. As shown in FIG.

The opening regulating means 40 includes a lever 41 exposed at an upper end of the second water dam plate 22 and a screw connected downwardly to the lever 41 to be connected to the second water dam plate 22, And an ascending / descending block 43 which is screwed to and elevated by the screw.

Here, the operation of the opening regulating means 40 for regulating the water inflow amount is as follows.

8 (b), when the lever 41 is rotated in one direction, the ascending / descending block 43 is raised by the rotation of the screw 42.

As the lifting block 43 is lifted up, the first water film 31 connected via the wire 44 simultaneously rises.

Since the opening degree of the opening and closing plate 30 is reduced, the water inflow amount can be reduced.

8 (a), when the lever 41 is rotated in the other direction, the ascending / descending block 43 descends, and the descending length of the ascending / descending block 43 is also lowered, .

The opening regulating means 40 described above can adjust the opening degree of the opening and closing plate 30 at a position relatively higher than the height of the opening and closing plate 30 so that the opening and closing plate setting operation can be smoothly performed inside the narrow manhole 200 Structure is provided.

On the other hand, a third water dam plate 14a having a relatively larger height than the second water dam plate 22 is coupled to both vertical frames 12a of the frame frame 10a.

The third diaphragm 14a guides the sewage, sewage, initial storm, and storm, while the elevating block 43 and the wire 44 exposed to the sides of the first and second diaphragm plates 31, The opening regulating means 40 also serves as an additional function for preventing foreign matter from being caught.

In addition, the second and third water dam plates (22, 14a) are fixed, while the first water dam plate (31) formed on the opening / closing plate (30) is movable.

7, the first water film plate 31 is formed by protruding a guide ball 33 for improving the operating reliability of the opening and closing plate 30. [

As shown in FIG. 8, the guide ball 33 is rolled in contact with the outer surface of the second water dam plate 22, so that the operation reliability of the opening / closing plate 30 can be improved.

Although the present invention has been described with reference to the preferred embodiments thereof with reference to the accompanying drawings, it will be apparent to those skilled in the art that various obvious modifications are possible without departing from the scope of the present invention. The scope of the invention should, therefore, be construed in light of the claims set forth to cover all such variations.
