The present invention solves the problem of the prior art while adopting the structure of the patent registration No. 10-1373478 filed by the present applicant as it is. Therefore, the construction and effect of the above-described prior art will be briefly described.

The non-power source immersion prevention device can be installed anywhere with pressure piping because it drains using pressure fluid in the piping, and it is easier to maintain and maintain than a pump using electricity. It is not only optimized but also easy to initial installation, automatic flood detection is automatic and maintenance is economical. There is a place where a drainage facility should be installed (place where the equipment is expected to be damaged by flooding), a valve room where electricity is not supplied, It is installed in a place where there is a risk of leakage of drainage pump due to submersion.

The connection pipe 100 of the present invention is branched to a manhole conduit 11 provided inside the manhole body 10 so as to be communicated with the outside, It is maintained in a state of being blocked by water pressure. The connection pipe 100 is provided with a water inlet 130 positioned at the front of the opening and closing valve 300 and an opening and closing valve 300 opened by the water inlet 200 to operate the ejector 500, And a discharge unit 150 which is discharged to the outside together with the water of the collecting unit 12 which is received through the water collecting unit 400.

The connection pipe 100 includes a first strainer 110 formed of a strainer for filtering foreign substances such as sand, gravel, leaves, vinyl, tree branches or the like in a pipe, a water meter 120 installed around the first strainer 110, A second strainer 140 which is a filter provided in the intake part 130 and a second strainer 140 which is a filter provided in the inlet part 130. The second strainer 140 is disposed at the rear of the ejector 500, And a discharge unit 150 through which the water of the collecting unit 12 coming in through the furnace 400 is discharged.

The first strainer 110 is disposed at a front end of the water meter 120 so as to primarily filter foreign matter and the second strainer 140 is located at a front end of the opening and closing valve 300 and is smaller than the first strainer 110 Shaped foreign matter.

The valve 200 is installed at a lower portion of the opening / closing valve 300 and is vertically moved up and down by the buoyancy of water flowing into the water collecting portion 12 to open / close the opening / closing valve 300. The buoys may be various shapes such as round, oval, and the like.

6, the opening / closing valve 300 is provided with an opening / closing member 311 for opening / closing the connection pipe 100, and an opening / closing member 311 which is in close contact with the rear end of the opening / closing member 311, A spring 312 is fixed and a guide groove 321 is formed at an upper end of the guide groove 200 to allow the support rod 310 to be inserted into the guide groove 321, 322 are provided to allow the opening and closing member 311 to be opened by a magnetic force.

The opening and closing valve 300 is maintained at a state where the opening and closing member 311 is blocked by the spring 312 and the valve 200 is installed at the upper end of the valve 200 when the valve 200 is floated, The operation member 320 is inserted into the support base 310 and the opening and closing member 311 is pulled in the support base 310 in the direction of the magnet 322 by the magnetic force of the magnet 322 in the operation body 320 And the ejector 500 is operated in a state in which the conduit is opened.

The opening / closing valve 300 is operated by shutting off or opening the opening / closing valve 300 by means of a buoy 200 which is lifted or lowered by the flooded water level, so that the user can be flooded without an electric facility, It becomes possible to take an immediate action according to the water and simplify management.

The non-power source immersion prevention apparatus of the present invention includes an inlet pipe 620 connected to an upper portion of the inlet 200 and a lower portion of the operating body 320 and connected to a first control valve 610 installed in the outlet 150, And a water discharge guide hole 631 for discharging a small amount of water to one side of the bottom surface of the water storage tank 630. The water discharge hole 631 is formed in the bottom of the water storage tank 630, Is formed.

The non-power source immersion prevention device is configured such that when the opening and closing valve 300 of the connection pipe 100 is opened by the rising of the mouth 200 to operate the ejector 500, A predetermined amount of water flows into the water collection tube 630 through the inlet tube 620 which is a branched tube disposed at the rear end of the ejector 500 and the load of the water flowing into the water collection tube 630 flows into the water collection tube 630, 200, and when the buoy 200 is lowered, the opening / closing valve 300 is closed and the operation is stopped, so that the discharge of the flooded water is stopped.

The first control valve 610 is provided at the rear end of the ejector 500 to discharge the flooded water discharged from the suction pipe 400 through the ejector 500 to the water collection pipe 630 ). The first control valve 610 is installed in the discharge unit 150, but may be installed on the inlet pipe 620. When the speed of the water flowing into the water collection container 630 is determined according to the degree of opening of the first control valve 610 and the opening speed is increased, the opening / closing valve 300 is quickly closed after opening, The opening and closing valve takes a long time to close after opening. If the opening / closing valve 300 is closed and water is not transmitted from the ejector, water is not transferred to the inlet pipe 620 so that no further water is collected in the water collection container 630.

At this time, a drainage guide hole 631 for discharging water is provided in the lower part of the water collection container 630, and a second control valve 640 for controlling the degree of opening of the drainage guide hole 631 is provided, The water is discharged through the holes and the amount of water in the water storage container 630 is reduced according to the discharge of water. When the weight of the water storage container is less than the buoyancy of the water storage container 200, Accordingly, the opening / closing valve 300 is opened, water is delivered from the suction pipe 400 through the ejector 500, and the non-power source immersion prevention device is activated again. When the non-power source immersion prevention device is operated again, water is transferred to the inflow conduit 620 through the discharge portion and water is collected in the water collection container 630.

If the opening degree of the second control valve 640 is increased, the amount of water exiting the water storage container 630 is increased to shorten the closing time (stopping time) of the opening / closing valve 300, The amount of water flowing out of the collection cistern is small and the closing time (stopping time) of the opening / closing valve 300 becomes long.

By repeating the operation of stopping the operation of the non-electric water immersion prevention device, stopping the operation of the non-electric water immersion prevention device, and then stopping the operation of the non-electric water immersion prevention device, the efficiency of discharging water is increased more than that of the conventional drainage device .

The ejector 500 generates a vacuum suction force by jetting the water flowing through the connection pipe 100 at a high speed by the nozzle while opening the on-off valve 300, and by the suction force generated by the nozzle, The water in the water collecting part 12 is discharged together with the discharge part 150 by the suction force. Since the structure and operation of the ejector 500 are described in detail in the related arts registered by the present applicant, a detailed description thereof will be omitted in the present invention.

However, when the water immersed in the suction pipe 400 is sucked by the vacuum suction force injected by the nozzle of the inflow water, the vacuum suction force is not always maintained but weakens gradually over a certain period of time. The weakening time depends on the structure of the ejector, the size of the pump, the strength of the pump, and the pressure of the influent water. Vacuum suction is weakened in 2 to 15 minutes. When the vacuum suction force is weakened, the force of pulling out the flooded water from the suction pipe 400 is weakened and the amount of water to be discharged is reduced.

In order to reinforce the vacuum suction force that weakens over a period of time as described above, the present invention moves the water storage tank 630 up and down, stops the operation at the point of time when the vacuum suction force is weakened by opening and closing the open / close valve 300, The ejector 500 can be operated only while the vacuum suction force is maintained at the maximum by opening the on-off valve 300 again. 5 (a) shows the operation (operation) time and the stopping time of the opening / closing valve 300, and Fig. 5 (b) shows the amount of water collected in the water collection container 630. Fig. 5 (b), the water collecting box 630 is increased from the moment the ejector 300 is opened to the moment when the ejector 300 starts to be collected and the on-off valve 300 is closed, and when the on- There is no water flowing from the water guide hole 620, and only the water discharged to the drain guide hole 631 is present and gradually decreases. If the water in the collection cistern decreases to some extent and the cistern 200 rises, the opening / closing valve 300 is opened again and water flows in the inflow conduit 620, so the amount of water in the collection cistern 630 increases. As the operation is repeated, the open / close valve 300 is repeatedly opened and closed, and the operation time can be adjusted only when the vacuum suction force of the ejector 500 maintains the maximum value, so that the discharge efficiency of water can be increased.

 The amount of water flowing into the water collection tube 630 is adjusted by the first control valve 610 and the amount of water discharged through the water discharge guide hole 631 is controlled by the second control valve The amount of water flowing into the water collection tube 630 through the inlet pipe 620 is set to be larger than the amount of water discharged through the water discharge guide hole 631 so that water is supplied to the water collection tube 630 And when the amount of water discharged through the drain guide hole 631 is larger than the amount of water flowing into the water collection container 630, it becomes impossible to set the stop time and the operation time.

Accordingly, the first regulating valve 610 regulates the operation time of the non-power immersion prevention apparatus, and the second regulating valve 640 regulates the time during which the non-power immersion prevention apparatus stops. .

In the present invention, the suction path 400 is closed by the suction port of the conventional non-power source drainage apparatus. In the present invention, the first filtering network 410, which is closed at the lower end surface 411 and formed as a plurality of through holes at the side surface, ).

The suction pipe 400 is vertically installed at a predetermined distance from the bottom of the water collecting part 12 and is connected to the ejector 500. The suction pipe 400 is vertically moved on the outer surface of the water collecting part 12 in accordance with the water level of the water collecting part 12 The buoyant means 420 is installed and the second sieve 430 formed at the lower portion of the buoyancy means 420 is overlapped with the first sieve 410.

The lower end face 411 is extended outwardly from the lower end of the first squeezing net 410 so that the second squeezing net 430 and the first squeezing net 410 are overlapped, As shown in Fig.

As shown in FIG. 3, the buoyant means 420 may be formed in a shape having a larger diameter than the suction pipe 400 on the outer circumferential surface of the suction pipe 400, The lower portion is opened, and the inner portion is made as an empty space. The second squeezing unit 430 includes a first squeezing unit 410 and a second squeezing unit 430. The second squeezing unit 430 includes a first squeezing unit 410 and a second squeezing unit 430. The second squeezing unit 430 includes an air bag, And scrape off foreign matter when the first and second screens 410 are lifted and lowered.

The upper end of the first filtering net 410 is positioned lower than the maximum height at which the second filtering net 430 is lifted by buoyancy.

The non-power source immersion prevention apparatus of the present invention is installed in a connection line 100 branched from a manhole line 11 as a drainage device installed in a collecting part 12 formed at the bottom of a manhole, The ejector 500 is operated to discharge water to the discharge portion 150 of the connection pipe 100 together with the water immersed in the water. Normally, when the water flowing into the water receiving portion 130 is blocked by the on- When the inside of the manhole is flooded by the inflow of rainwater and sewage, the buoyant 200 is vertically raised by the buoyant force, and the on / off valve 300 is opened.

The opening and closing valve 300 includes a magnet 322 inserted into the guide groove 321 of the actuating member 320 installed at the upper portion of the cavity 200, The opening and closing member 311 is pulled in the direction of the magnet 322 by the magnetic force so that the spring 312 is compressed by the magnetic force in the support base 310 and the channel is opened.

When the on-off valve 300 is opened, the water in the collecting part 12 is discharged to the outside through the discharge part 150 along the suction pipe 400 connected to the lower part by the suction force generated through the ejector 500 The discharge unit 150 is provided with a first check valve 160 to prevent water discharged to the discharge unit 150 from flowing backward.

Since the water is accumulated from the rear end of the check valve 160 when there is a strong cold wave, the water inside the discharge part is frozen from the rear end of the discharge part to clog the discharge part do. In the present invention, the bypass pipe 170 is further provided with a manual opening / closing valve 180 to prevent the water from being left in the discharge unit 150 in order to prevent the discharge pipe from being clogged by the cold wave.

That is, the non-power source immersion prevention apparatus of the present invention selectively uses the first check valve 160 and the manual opening / closing valve 180 according to a site of a freezing wave, Off valve 180 located in the bypass piping 170 to remove water in the discharge portion and close the manual on-off valve 180 in a non-freezing site. When the manual opening / closing valve 180 is opened, the water in the discharge portion flows backward, causing a problem that the water in the water collecting portion 12 becomes floated. Therefore, the opening of the manual opening / closing valve 180 is provided for solving a larger problem caused by the freezing in the discharge portion even in such a problem, and it should be used according to the situation in each region.

Therefore, in the non-power source immersion prevention system of the present invention, the opening and closing valve 300 is automatically opened by the access port 200 that ascends and descends by the water level when the flooding occurs in the manhole, and the water is flooded in the manhole by the suction force generated through the ejector 500 Water can be rapidly discharged to the outside through the suction pipe 400 to prevent corrosion or breakdown of the facility by flooding, and it is possible to immediately cope with the flooding by the person without any operation, The installation cost is reduced as compared with the drainage method using the conventional pump and the pause time is set during the operation by the amount of water flowing into and discharged from the water collection container 630 provided at the upper portion of the water inlet 200, .

In addition, the non-power source immersion prevention system of the present invention is characterized in that the second sieve network 430 formed at the lower portion of the buoyancy means 420, which vertically ascends and descends according to the water level, on the outer circumferential surface of the suction pipe 400, The suction efficiency can be increased by overlapping the first sieve 410 formed at the lower part of the furnace 400 and removing the foreign matter caught in the first sieve 410. [

The non-power source immersion prevention apparatus of the present invention further includes a first control valve 610 installed in an inflow conduit 620 through which water flows into the water collection container 630, By using the second control valve 640 installed in the guide hole 631, it is possible to further increase the operation efficiency by setting the start and stop time during operation.

The non-power source immersion prevention apparatus of the present invention is characterized in that a first check valve 160 is installed in a discharge part 150 where water exits to the outside and a manual opening / closing valve 180 is installed in a bypass pipe 170, 1 check valve (160) or manual opening / closing valve (180) can be selectively used according to the site, freezing of drain pipe is not generated in winter, drainage function is maintained at all times, And the failure rate is low due to simple structure and function.
