Field of the Invention The present invention relates to a domestic wastewater sending device for sending domestic wastewater discharged from individual places such as homes to sewage facilities and the like. 2. Description of the Related Art Conventionally, this type of domestic wastewater discharge device has a storage tank buried in the ground near an individual place (hereinafter referred to as “home”) such as a home, and a home-based drainage device is provided in the storage tank. The system is configured to receive domestic wastewater and send the received domestic wastewater to the sewage main pipe by pumping using a pump built in a storage tank or by suction through a vacuum valve of a vacuum facility. Therefore, if this household wastewater sending device is used, even domestic household wastewater (hereinafter referred to as “drainage”) located farther than the location of the main sewer can be treated by connecting to a public sewer, and furthermore, It has the feature that sewerage can be economically spread even in areas with rugged terrain or large terrain. In order to send out the drainage from the storage tank, a pressure-type water level gauge is provided in the storage tank, and when the water level becomes higher than a certain level, the pump is driven to rotate, or the vacuum valve is opened. When the water level falls below a predetermined level, the rotation of the pump is stopped or the vacuum valve is closed. [0004] However, since the above-mentioned conventional domestic wastewater delivery device is a pressure-type water level gauge, a part of the water level gauge must be open to the atmosphere, and the storage tank must be open to the atmosphere. The manhole could not be sealed.
In particular, due to the housing situation in Japan, storage tanks are often buried underground in garages, etc. Therefore, the manhole cover is tightly closed and strong manhole cover which does not infiltrate water and does not leak odor. Was desired. [0005] In order to solve such problems, it is conceivable to use an electrode type water level gauge.
There are many erroneous detections due to the occurrence of scum and detection failures due to electrode corrosion, and there is no simple and reliable detection means that is superior to a pressure type water level gauge. Accordingly, the present invention has been made to solve the above-mentioned drawbacks, and an object of the present invention is to accurately measure the water level in a storage tank with a pressure-type water level gauge even if the storage tank has a closed manhole cover. It is an object of the present invention to provide a domestic wastewater sending device that can detect the wastewater. [0007] In order to achieve the above object, a domestic wastewater delivery device according to the present invention is a place for receiving wastewater discharged from a home through an inflow pipe communicating with the atmosphere. A storage tank buried therein, a closed manhole cover provided in the storage tank, and a driving part and a control part are housed in a closed container, and the water level in the storage tank has become a predetermined level or more. Draining drainage to sewerage facilities or the like through an inflow pipe at times, drainage means provided in the storage tank, a pressure-type water level meter for detecting the water level in the storage tank, and block the passage of liquid, And a diaphragm provided on a part of the wall surface of the closed container, which allows gas to pass therethrough. In the above configuration, the pressure in the closed vessel becomes equal to the atmosphere through the diaphragm, and the pressure type water level gauge can function normally. Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic diagram of a sewage system to which the present invention is applied. In the figure, reference numeral 1 denotes a storage tank, which is a road surface (ground).
G is buried underground and one end (not shown) receives wastewater discharged from the home via an inflow pipe 2 which is in communication with the atmosphere, and the received wastewater is stored in a storage tank 1 via a pump P and an outflow pipe 3. It is configured so that it can be discharged to the sewage main pipe 4 buried at a higher place. FIG. 2 is an enlarged vertical sectional view of the storage tank 1. A manhole cover 5 provided on the same surface as the ground G is provided in a manhole 6 provided above the storage tank 1 in a sealed state. Have been. Therefore, water does not infiltrate into the storage tank from the manhole 6 or the odor does not leak from the storage tank 1 to the outside. The pump P is provided at the lower end of the auxiliary airtight container 7 and communicates with the auxiliary airtight container 7 and is suspended from the airtight container 8 having a motor M and a control unit C inside. It is provided. The pump P is a so-called snake pump having a cutter at a lower portion, and is configured to be able to pressure-feed wastewater to the sewage main pipe 4 via the outflow pipe 3 while crushing foreign substances. The pressure-type water level gauge S is a well-known pressure-type water level gauge that detects a pressure change due to a change in water level with reference to the atmospheric pressure. The detected signal is input to a controller C. I have. The controller C drives the motor M to rotate the motor M when the water level becomes higher than a predetermined level, and discharges the drainage in the storage tank 1 from the outflow pipe 3. On the other hand, when the water level falls below a predetermined level, Control is performed to stop the rotation of the motor M. The diaphragm 9 is a side wall of the auxiliary closed vessel 9, and a flange F provided above the upper limit water level in the storage tank 1.
It is provided in. The diaphragm 9 is formed of a known membrane that allows gas to pass but does not allow water to pass, such as that used in ski wear. Therefore, the air pressure in the closed vessel 8 is kept the same as that in the storage tank 1 via the auxiliary closed vessel 7 and the diaphragm 9. Moreover, since the inside of the storage tank 1 is in communication with the atmosphere via the inflow pipe 2, the pressure type water level gauge S can normally detect the water level. In the above-described embodiment, the pump P is used as a means for sending out waste water. However, in the case of a vacuum type, the opening and closing of the vacuum valve is controlled by the controller C. Although the closed container is connected to the auxiliary closed container, the closed container 8 may be made longer and the auxiliary closed container 7 may be omitted. The domestic waste water delivery device according to the present invention can prevent the passage of water and use a diaphragm that allows the passage of gas to take in the atmospheric pressure used in the pressure type water level gauge. Therefore, it is possible to use a pressure-type water level gauge even if the manhole cover is sealed.
