Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a vacuum sewage collection device for collecting sewage discharged from a large number of households and facilities.

[Conventional technology]

FIG. 3 is a diagram showing the configuration of a conventional vacuum type sewage collection device.

As shown in the figure, in the conventional vacuum type sewage collection device, sewage discharged from each household 50 above ground flows into an underground sewage basin 53 through a gravity drainage type sewage pipe 51 underground. When a certain amount of sewage accumulates in this sewage basin 53, a vacuum valve 55 attached to the top of the sewage basin 53 opens, and the sewage in the sewage basin 53 is sucked through the suction pipe 57. This sewage is then sucked into a vacuum sewage pipe 59 installed underground through a vacuum valve 55, and collected in a water collection tank of a vacuum pumping station (not shown).

Here, a predetermined portion of the gravity drain type sewage pipe 51 has an air intake of 1f.
61 is connected. This intake pipe 61 is raised up to a predetermined height above the ground surface and has an open end so as to avoid the risk of sucking in surface water.

On the other hand, a vacuum valve controller 63 that controls opening and closing of the vacuum valve 55 is attached to the vacuum valve 55 . This vacuum valve controller 63 opens the vacuum valve 55 when the amount of sewage in the sewage basin 53 exceeds a predetermined amount, and closes after the amount of sewage falls below a predetermined amount and the suction pipe 57 sucks a predetermined amount of air. Control as follows.

This vacuum valve controller 63 also includes a breather pipe 6.
5 is connected, and its upper end is raised up to a predetermined height above the ground surface and opened to prevent the risk of sucking in surface water. This breather pipe 65 supplies atmospheric pressure to the vacuum valve controller 63. Vacuum valve 5
5 operates by utilizing the differential pressure between this atmospheric pressure and the vacuum pressure inside the vacuum wastewater pipe 59.

The structure of this vacuum valve controller 63 is disclosed, for example, in FIG. 5 of Japanese Patent Application No. 1-111329.

Further, a detector 67 is attached to the vacuum valve 55 to detect whether the vacuum valve 55 is opened or closed. This detector 6
7 is connected to a failure alarm device 71 by a signal transmission line 69.

When the vacuum valve 55 fails, the signal is transmitted from the detector 67 to the failure alarm device 71, and the failure alarm device 71 issues an alarm. The details of this device are disclosed in, for example, Japanese Patent Application No. 1-177365.

[Problem to be solved by the invention]

However, in the conventional vacuum type sewage collection device as shown in FIG.
+111) intake pipe 61 and a breather pipe 65 of relatively small diameter (for example, diameter 251111) are connected to one vacuum valve 5.
Since it stands on the ground separately from the vacuum sewage collection system 5, there is a problem in that it obstructs the landscape of the area where this vacuum sewage collection system is buried.

In addition, the breather tube 65 had a small diameter and was easily broken.

Furthermore, the failure alarm device 71 was installed on the outside wall of a private house or facility 50, or on a utility pole near the vacuum valve 55, but it is also possible to install a public device such as the failure alarm device 71 in a private house or a facility owned by a private company. When attaching the device to a person, etc., there were problems such as the need to obtain the consent of the person concerned.

Further, since the failure alarm device 71 was installed in various locations, there was also the problem that it was difficult to maintain and manage where the failure alarm device 71 was installed.

The present invention has been made in view of the above points, and improves the scenery of the area where the vacuum sewage collection device is buried, makes the breather pipe less likely to break, and furthermore allows a failure alarm device to be installed in public facilities. An object of the present invention is to provide a vacuum type sewage collection device.

[Means to solve the problem]

In order to solve the above-mentioned problems, the vacuum sewage collection device according to the present invention inserts at least the part of the breather pipe exposed above the ground into the inside of the intake pipe, and sets the opening at the tip of the breather pipe at a predetermined height above the ground within the intake pipe. The structure was designed to be located in a high place.

Further, the vacuum type sewage collection device according to the present invention has a structure in which the failure alarm device is attached inside the portion of the intake pipe that protrudes above the ground surface.

Further, the vacuum type sewage collection device according to the present invention has a structure in which various types of display such as an address display and a road sign are provided on the outer surface of the portion of the intake pipe that protrudes above the ground surface.

[Effect]

As described above, the breather pipe is inserted into the intake pipe, so that only the intake pipe appears above ground. Furthermore, the breather pipe is protected by the intake pipe and will not be destroyed.

Furthermore, since the failure alarm device is installed inside the portion of the intake pipe that protrudes above the ground surface, the installation of this failure alarm device does not require permission from a private company or the like, making the installation easy. Moreover, the installation position of the failure alarm device becomes constant, and its maintenance and management becomes easy.

In addition, if various types of displays such as an address display or a road sign are provided on the outer surface of the portion of the intake pipe that protrudes above the ground surface, the intake pipe can be used effectively.

〔Example〕

Hereinafter, one embodiment of the present invention will be described in detail based on the drawings.

FIG. 2 is a diagram showing the overall configuration of a vacuum type sewage collection device to which the present invention is applied.

As shown in the figure, in this vacuum type sewage collection device,
A gravity drain sewage pipe 1 that carries sewage discharged from homes and facilities 30 outside, a sewage basin 3 that collects the sewage discharged by the gravity sewage pipe 1, and a sewage basin 3 that collects the sewage collected in the sewage basin 3. A suction pipe 5 to suck up the sewage, a vacuum sewage pipe 7 that sends the treated sewage to a water collection tank (not shown) in a vacuum tank station, and a vacuum sewage pipe 7 attached near the tip of the vacuum sewage pipe 7 to open and close the vacuum sewage pipe 7. The vacuum valve 9 is provided with a vacuum valve 9 and a vacuum valve controller 11 that controls opening and closing of the vacuum valve 9. Further, the vacuum valve 9 has a detector 1 for detecting the operating state of the vacuum valve 9.

No. 5 has a sufficient area for inhaling air, is protected by a wire mesh, and is configured to prevent foreign matter from entering. Further, the intake ports 25, 25 are provided at a height that prevents water overflowing from the ground surface from entering the intake pipe 15 even in the event of heavy rain or the like.

The above-mentioned breather pipe 19 and signal transmission line 21 are introduced inside this ground exposed part 15a, a filter 27 is attached to the tip of the breather tube 19, and a failure alarm is installed at the tip of the signal transmission 11121. A device 29 is attached.

Here, the position of the opening where the filter 27 of the breather pipe 19 is attached is such that in the unlikely event that the vacuum valve 9 malfunctions and the sewage is not sucked from the suction pipe 5 and the sewage in the sewage tank 3 overflows, the suction pipe 15 The height is such that even if the lower part is filled with sewage, the sewage will not enter.

Also, on the outer surface of the above-ground exposed portion 15a of this intake pipe 15,
An address display board 31 is attached.

This increases the usefulness of the intake pipe 15 and makes it easier to penetrate the area. Furthermore, by using this address name, it becomes easier to manage failures of the vacuum valve 9, etc.

Although the embodiments of the vacuum sewage collection device according to the present invention have been described above in detail, the present invention is not limited thereto, and for example, the following modifications are possible.

(2) In the above embodiment, the intake pipe 15 is directly connected to the wastewater basin 3, but the intake pipe 15 may be attached to a predetermined portion of the gravity drain type wastewater pipe 1.

(2) In the above embodiment, almost all of the breather pipe 19 and the signal transmission line 21 are inserted into the intake pipe 15, but the present invention C is not limited to this.
The signal transmission line 21 may have a structure in which at least the portion thereof exposed above the ground is inserted into the intake pipe 15.
