Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water tank monitoring device, and more particularly to a water tank monitoring device suitable for confirming false alarms of full water and low water.

[0002]

2. Description of the Related Art Elevated water tanks and water receiving tanks detect the water level,
It controls the pump etc. to supply and stop water,
When the water level detector detects the positions of the preset full water level and reduced water level in order to know in advance that water in the aquarium will overflow or be depleted due to abnormalities in the control of water supply or stoppage,
It is configured to report an alarm to a monitoring center that monitors remotely via a communication line such as a telephone line.

However, the full water level may be erroneously detected due to the waves generated on the water surface during an earthquake or water supply, and the notification due to the erroneous detection due to the waves generated on the water surface is reduced.
In Japanese Unexamined Patent Publication No. 4-232596, a full water detector for detecting a full water level and an upper water level detector which is set to a water level slightly lower than the detection water level of this full water detector and which stops water supply simultaneously detect the water level. Only in this case, the technology for notifying the monitoring center of the alarm of full water detection is described.

[0004]

The above-mentioned prior art can reduce the alarm due to the false detection of the full water level caused by the waves generated on the water surface of the aquarium. However, if the alarm is received and the inside of the aquarium at the site is confirmed, In many cases, the water level is not at the full water level or the low water level, and it is not possible to confirm whether or not the water level is full or low, so it takes time because the investigation range for the cause of the alarm is wide. However, it is necessary to stop the use of the water tank and raise and lower the water level to reproduce the state of full water or low water, which causes a great inconvenience to the residents of the building.

It is an object of the present invention to provide a monitoring device in a water tank which can grasp whether or not the water level in the water tank is full or low.

[0006]

To achieve the above object, in order to achieve the above object, a water supply control device for controlling water supply according to the water level of a water tank, a full water and a low water level of the water tank is detected by a full water and a low water detector, and a communication line is connected. In a water tank monitoring device that sends a warning of fullness and low water to a monitoring center that remotely monitors building facilities via a rod-shaped body fixed to at least one of the upper surface and the lower surface of the water tank, and the water surface in the water tank. And a float that moves along the rod-shaped body and floats in the air, and at least one adsorbent that is movably fixed to the rod-shaped body.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 is a schematic cross-sectional view of an elevated water tank showing an embodiment of the water tank monitoring apparatus of the present invention, and FIG. 2 is an enlarged view of a main part of FIG.

In the figure, when the motor 2 directly connected to the pumping pump 1 rotates, water is supplied from the water receiving tank installed in the basement or the first floor of the building to the elevated water tank 4 through the introduction pipe 3, and the elevated water tank. Water in 4 is supplied to each home (not shown) through a water supply pipe 5.

In addition, the elevated water tank 4 is provided with a water level detection device 6 and an overflow pipe 7 on the side surface near the uppermost portion, and the water level detection device 6 has a common end whose end portion hangs down to near the bottom portion of the elevated water tank 4. A rod 6A, a water reduction detection rod 6B whose end is located slightly above the common rod 6A, a water supply start water level detection rod 6C whose end is located slightly above the water reduction detection rod 6B, and a little below the overflow pipe 7. Full water detection rod 6 where the end is located
D and a water supply stop water level detection rod 6E whose end is located slightly below the full water detection rod 6D.

Further, a pipe 8A having a predetermined length and having a screw on the inner wall, and an adjusting stand for screwing the both ends of the pipe 8A so that the pipe 8A is brought into contact with the upper and lower surfaces of the water tank 4 and the pipe 8A is erected. 8B and a rod-shaped body is formed, and a donut-shaped magnetic float 9 made of iron is inserted into the pipe 8A.
A magnet 10 for confirming full water which is an adsorbent on the upper and lower parts of the pipe 8A
A and the water reduction confirmation magnet 10B are attached respectively, and the full water confirmation magnet 10A and the water reduction confirmation magnet 10B are attached to the water surface H.
Is the end of the full water detection rod 6D and the reduced water detection rod 6B, the float 9 is filled with the full water confirmation magnet 10A and the reduced water confirmation magnet 1
It is fixed with a screw 10C at a position such that it attaches to 0B.

Next, the operation of this embodiment will be described.

Now, when the water level H in the elevated water tank 4 falls and the water supply start water level detection rod 6C stops contacting the water level H, the water detector 6 activates the motor 2 to supply water into the elevated water tank 4. When the water supply stop water level detection rod 6E comes into contact with the water surface H, the motor 2 is stopped and the water supply is stopped. Further, if the water level H is lowered and water is not supplied and the water reduction detection rod 6B does not come into contact with the water level H, the elevated water tank 4 is sent to a monitoring center (not shown) for remotely monitoring the building equipment for an abnormality via a telephone line. A signal indicating that the water level has decreased is transmitted, and even if the water level H rises, the water supply does not stop and the full water detection rod 6D contacts the water level H. Send a signal.

Here, for example, when the wiring of the water level detecting device 6 is temporarily broken due to bending, and a half-breakage state in which the wiring is connected at the return of the wiring occurs in the wiring of the water reduction detection rod 6B and becomes a temporary disconnection state. A water reduction warning is sent to a monitoring center (not shown), and an operator who receives a restoration instruction from a monitoring staff (not shown) goes to the site and goes through the inspection port 4 of the elevated water tank 4.
When the water surface H is confirmed from A, the water surface H has not descended to the water reduction position, and the float 9 is floating at the position of the water surface H. Therefore, the water reduction alarm is an erroneous detection of the water reduction detection rod 6B. The cause of can be specified that the opening of the electric circuit is effective.

As described above, since it is possible to reliably determine whether or not the alarm is erroneously detected at the position of the float 9 with respect to the transmission of the alarm of full water or low water related to the remote monitoring of full water or low water of the elevated water tank, It is easy to identify the cause and become able to perform it in a short time.

Although the present embodiment has been described with reference to the low water alarm,
The same applies to the full water alarm, so the description is omitted. Also, the same effect can be obtained in the water receiving tank.

[0017]

According to the present invention, the float floating on the surface of the water in the water tank is adsorbed and held by the adsorbent when the water level becomes full and the water level is reduced. As a result, false detection and identification of the cause can be specified in a short time.
