Description

Automatic sewage sampler for manhole

The present invention relates to a manhole automatic watering apparatus, and more particularly, to a manhole automatic watering apparatus which is installed in a manhole and is movable so as to automatically take sewage flowing into a sewer pipe at different times.

In general, sewage samples are taken from the manhole of the selected area to measure the quality of the sewage. Sampling of the sewage is carried out regularly or whenever necessary and more frequently in the vicinity of the source.

Conventionally, in order to collect sewage samples in a manhole located at a certain point of the sewer pipe at the time of collecting the sewage, the operator carried the equipment for taking the water with the water taking into the moving vehicle.

In addition, sewage samples are sampled a plurality of times at regular time intervals for each manhole. For example, sewage samples are collected six times at intervals of two hours in one manhole, thereby monitoring the quality of sewage water by time.

However, in the above case, since the operator must directly collect the sewage samples during daytime and nighttime, there is a problem that work fatigue increases, frequent safety accidents occur, and it is difficult to collect sewage samples at the correct time.

Accordingly, a regeneration utility model No. 20-0335202, "automatic sewage sampling apparatus in sewage manhole", proposes a technique of automatically extracting sewage water from the outside without opening a manhole cover by using an air pump and a suction pipe.

However, the above registered utility model No. 20-0335202 is advantageous in that the operator can collect sewage samples from the ground without going down the manhole, and it is difficult to install the equipment itself, have.

Also, Korean Patent No. 10-1513463, entitled " Manhole-type automatic sifting machine applicable to a main sewer pipe ", proposes an automatic rotation watering device for rotating the bucket elevator at a predetermined time period.

However, Korean Patent No. 10-1513463 discloses that the bucket is rotated at a predetermined time period and the sewage in the manhole is pumped up to the ground. However, in this case, the operator is always waiting on the ground, There is a problem to be included.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Hereinafter, a manhole automatic watering apparatus according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, the manhole-type automatic watercourse apparatus 100 according to the present invention includes a water collecting body B, a suction pump 110, a suction pipe 120, a supply pipe 130, a branch pipe 140, a pot 150, and a valve module 160. [

As another preferred embodiment of the present invention, the apparatus may further include a sieve pipe 121 installed on an inlet side of the suction pipe 120 and a bypass pipe 170 connected to be branched at an upper portion of the supply pipe 130 .

In the present invention as described above, the sewage pumped through the suction pipe 120 flows into the supply pipe 130 during the operation of the suction pump 110, and is discharged from the supply pipe 130 by the valve module 160 And sequentially supplied to a plurality of branch pipes 140 branched.

Therefore, since sewage samples of each hour are automatically collected in the water bottle 150 assembled in the branch pipes 140, it is possible to reduce the work fatigue and safety accidents during the installation of the apparatus and during collection, Allow the sample to be collected.

For this purpose, the receiving vessel (B) can be configured as a box having various shapes such as a rectangular box or a cylindrical shape, and has a space in which various technical constructions of the present invention to be described later are installed.

The water collecting container B is installed by lowering the manhole cover to the bottom surface of the manhole by one opening and the opening and closing door D is installed on one side of the water collecting container B so that the vessel 150 can be mounted, I can do it.

Of course, since the water collecting housing B is used under a harsh environment inside the manhole, it is preferable to provide a sealing means as a sealing means for preventing various foreign substances, moisture or sewage from being introduced.

Next, the suction pump 110 is installed in the water collecting container B to raise the sewage water sample flowing along the bottom of the manhole to the water collecting container B, and is preferably mounted inside the water collecting container B. Of course, since the present invention is not installed so as to be submerged in sewage, it may be installed on the outer surface of the water receiving casing B.

The suction pump 110 may be a dry pump or a submersible pump. The suction pump 110 may be powered from a battery (not shown) mounted on the suction pump 110 so that the suction pump 110 can be used as a portable type It works.

Next, the suction pipe 120 is a pipe for lifting up the sewage at the bottom of the manhole to the upper portion. The one end (for example, the lower end) extends to the sewer pipe through which the sewage flows and is exposed to the outside of the water receiving housing B, Is connected to the inflow side of the suction pump 110.

The suction pipe 120 is extended to an invert (IV) of the sewer pipe as described below with reference to FIG. 3 below. Invert (IV) refers to a semicircular groove that is installed at the bottom of a manhole to guide and flow sewage, as is well known.

Therefore, by providing the one end of the suction pipe 120, that is, the lower end opening to the invert IV, it is possible to reliably collect sewage flowing along the invert IV made of semicircular grooves even when the amount of sewage is small.

Next, the supply pipe 130 is for distributing the sewage drawn up along the suction pipe 120 to the different branch pipes 140 by the operation of the suction pump 110, 110, and the other end extends to the sewer line.

This supply pipe 130 is connected to the supply pipe 130 only at that time because the suction pump 110 is operated only during the collection of the sewage water sample as described in the embodiment with reference to the valve module 160 below The sewage flows.

Next, the branch piping 140 is for feeding the sewage sample supplied from the supply piping 130 to the vessel 150, and a plurality of branch piping 140 are installed so as to branch off from the supply piping 130 and have a tree branch shape as a whole.

As shown in FIG. 1, the branch pipe 140 may be inclined upwards in a direction away from the supply pipe 130, and then downwardly inclined.

Therefore, the upwardly inclined portion prevents steep flow of the sewage sample (or change in water pressure), and the downward inclined portion stably flows the sewage sample toward the vessel 150.

At least one of the plurality of branch pipes 140 is installed at a height different from the height at which the other branch pipe 140 is connected to the supply pipe 130. That is, it is preferable that all the branch pipes 140 are not installed along the circumferential direction of the supply pipe 130 at the same height of the supply pipe 130.

Therefore, as one embodiment, some of the branch pipes 140 are branched and installed along the circumferential direction at the same height of the supply pipe 130, and the rest are branched and installed along the circumferential direction at different heights below and above .

Next, the water vessel 150 collects and stores the sewage in each set time, and is assembled detachably to the end of the branch pipe 140, and the sewage branched into the branch pipe 140 from the supply pipe 130 We collect.

The vessel 150 may be made of various materials including glass, plastic, or metal. For a specific purpose, a chemically stable material may be selected and assembled into the branch pipe 140.

In this embodiment, the water bottle 150 has a shape of a triangular flask, and a thread is formed in the upper end bottleneck portion so as to be assembled in a threaded manner to a cap (formed on the inner circumferential surface) formed at the end of the branch pipe 140.

Next, the valve module 160 is composed of one or more kinds of valve bodies, so that a plurality of branch pipes 140 are sequentially opened at predetermined time intervals, and the sewage is collected into the different pot bottles 150 every set time I will crack down.

Specifically, the valve module 160 is a normally open type valve 161 that is open and performs a closing operation upon input of a control signal, and a normally open type valve 161 that is closed, A closed valve 162 'and a control unit 163 for controlling them.

At this time, the normally open type valve 161 is installed in the supply pipe 130. When the water is not supplied, the valve 161 is opened and closed when the water is drawn. When the water is supplied from the upper end of the supply pipe 130, Respectively. In particular below the branch piping 140 to be controlled.

Accordingly, as the suction pump 110 is operated, the sewage supplied to the supply pipe 130 flows along the supply pipe 130 and is blocked by the normally open type valve 161 having the closing action, The sewage flows into the branched branch pipe 140 in an open state.

On the other hand, the normally-closed valve 162 is installed in each of the plurality of branch pipes 140. When the water is not collected, the normally-closed valve 162 is closed and opened when water is taken. 140).

Accordingly, the sewage water that has been backwashed by the normally open type valve 161 that has been subjected to the closing operation as described above passes through the normally closed type valve 162 in which the opening operation is performed, and is collected into the sachet 150.

The control unit 163 is for controlling the operation timing of the normally closed type valve 162 and the normally open type valve 161 as described above and is provided with a normally open type valve 161 ) And closing and closing of the closed type valve.

For example, as shown in FIG. 1, a plurality of branch pipes 140 and a water bottle 150 assembled therein are installed in two stages (1st floor, 2nd floor), and a total of six branch pipes 140 And the sewage samples are collected at intervals of 2 hours in each vessel (150) for 12 hours.

At this time, when three branch pipes 140 are provided on the first floor (upper floor) and the lower second floor (second floor), respectively, The open valve 161 is closed and at the same time the normally closed valve 162 installed in the first branch pipe 140 of the three branch pipes 140 is opened.

Therefore, at the point of 2 hours after the installation, since the sewage water flows into the first branch pipe 140 only with the water bottle 150, the sewage water sampling at the first point is automatically completed.

After completing the collection of the sewage sample in the first branch pipe 140, the normally closed valve 162 installed in the first branch pipe 140 is closed (that is, returned), and the normally open valve 161 is again closed And returns (i.e., opens) to discharge the residual sewage sample downstream.

Thereafter, at the time when four hours have elapsed for the next sampling of the sewage, the normally open valve 161 of the first floor is closed again, and the normally closed valve 161 of the second branch pipe 140 is closed again. (162) is opened to collect sewage samples in another sailor (150) (i.e., second sailor).

In the same manner, even after 6 hours have elapsed, the sewage sample is collected. Thereafter, the normally open valve 161 of the first floor is kept open, and the first floor of the normally closed Type valve 162 maintains the closed state.

Further, for the water collection after 8 hours, 10 hours, and 12 hours, the normally open type valve 161 and the normally closed type valve 162 installed on the 2nd floor are controlled and set in the same manner as described above Sewage samples are collected over time.

As shown in FIG. 3, in the present invention, an installation foot S is provided at the lower end of the water receiving box B and a connection ring is provided at the upper end thereof. I will.

Therefore, the worker can tie the upper end of the manhole without pulling down to the bottom of the manhole, and the other end pulls the wire (W) tied to the connecting ring to collect the water-collecting housing (B)

As described above, one end (i.e., the lower end opening) of the suction pipe 120 is extended to the invert IV which is a semicircular groove for guiding and flowing the sewage in the sewage pipe, And a filtering net 121 is installed at the end.

As shown in FIG. 4, the screen 121 is for filtering various kinds of foreign materials (cigarettes, leaves, sludge, etc.) having a large size and passing only sewage water as a sample. The screen 121 is connected to the inside of the suction pipe 120 The elastic spring 122 is connected to the spring 122.

At this time, the elastic spring 122 is fixed to the inside of the end portion of the suction pipe 120. For example, the elastic spring 122 may be fixedly attached to the support pipe protruding into the suction pipe 120, The upper end (drawing reference) is caught.

One end of the connection pipe 123 is fixed to the sieve net 121, and the other end is supported by the elastic spring 122, and a flow path is formed therein. Therefore, while the flow of the sewage water flowing into the suction pipe 120 is enabled, the elastic spring 122 absorbs the shock due to water pressure or the like.

Next, returning to FIG. 1, the bypass piping 170 is operated by the suction pump 110 so that the water tank 150 is not subjected to excessive water pressure without interfering with the flow of the sewage water while collecting the sewage water sample prevent.

To this end, one end of the bypass pipe 170 is connected to branch from the upper part of the supply pipe 130, and the other end is installed to extend to the sewer pipe under the manhole. Thus, the remaining sewage supplied to the supply pipe 130 and the branch pipe 140 in the sewage is bypassed to the sewage pipe via the bypass pipe 170.

Finally, as shown in FIG. 5, the water collecting container (B) containing the water bottles (150) filled with the sewage water sample is pulled by the wire (W) After separating from the branch piping 140, the cap C is closed and sent to the laboratory.

Further, by inserting the new bottles 150 and B2 into the branch pipes 140, the new bottles 150 and B2 are moved to another manhole or the like so that the inspection can be continuously performed.
