Description

[Detailed description of the invention] [Industrial application field] The present invention automatically alarms indoors when the amount of oil in the fuel tank is low or when condensate accumulates at the bottom of the fuel tank. This relates to an oil level gauge with a drain alarm that emits.

[Problems to be solved by conventional techniques and ideas]

Generally, in heating appliances, boilers, etc., there are those in which a fuel tank is integrally provided in the main body, and those in which the main body and the fuel tank are connected by a pipeline and the fuel tank is installed outdoors.
(The latter is often used in cold regions where a large amount of fuel is consumed.) You can check the remaining oil level by looking at the oil level indicator, but if the fuel tank is installed outdoors. It is extremely troublesome to go out into the cold outdoors and check on the insects.

This invention is an oil level gauge with an alarm that can be checked with an alarm without looking at the indicator, and furthermore, can confirm the fact that condensate has accumulated in the fuel tank with an alarm. This is what we provide.

[Means to solve the problem]

The gist of the present invention will be explained with reference to the accompanying drawings.

Two guide rods 10 and 11 are vertically installed at a distance from each other on the lower surface of the pointer-readable oil level indicator 3 attached to the filler port 2 of the fuel tank 1, and the lower ends of the guide rods 10 and 11 A connecting body 22 is provided between them, a float 12 is provided on the guide rods 10 and 11 so as to be able to rise and fall freely, and a torsionally rotating plate 9 is provided vertically on the pointer shaft 8 at the center of the lower surface of the oil level indicator 3. The lower end of the plate 9 is connected to the through hole 12' in the center of the float 12.
The rotating plate 9 is fitted into the rotating plate 9 as the float 12 moves up and down.
In the oil level gauge a that reads the oil level with a pointer that rotates as the guide rod 10 rotates, one of the guide rods 10
is formed into a pipe, and the guide rod body 1 made of this pipe is
A sensor 6 is provided closer to the connecting body 22 of 0, a sensor movable body 13 is provided on the float 12, and a guide rod 10 made of a pipe is formed longer than the other guide rod 11 so as to protrude downward from the connecting rod 22. A drain float 15 that floats up when drain is generated is provided on this protruding portion 10' so as to be able to rise and fall freely, and a sensor actuating body 1 is attached to this drain float 15.
4, and a sensor 7 operated by a sensor actuator 14 is provided near the base of the protrusion 10' of the guide rod 10, and the sensors 6, 7 are arranged in upper and lower stages.
An oil drain alarm equipped with a drain alarm, characterized in that a conductor 21 is arranged at each of the terminals 7 and 7, which are connected to a conductor 25 of an alarm 5 through a connector 24, and the fuel tank 1 is installed outdoors and the alarm 5 is installed indoors. This relates to meters.

[Effect]

When the float 12 moves up and down as the amount of oil increases or decreases, the torsion rotating plate 9 rotates, causing the pointer shaft 8 to rotate and the pointer 4 to move.The movement of the pointer 4 is read and the amount of oil is determined. know.

When the float 12 descends to the lowest position, the sensor movable body 13 activates the sensor 6, and the indoor alarm 5 issues a warning that the oil level is low.

When drain accumulates at the bottom of the fuel tank 1, the drain float 15 rises and approaches the sensor 7, and the sensor movable body 14 activates the sensor 7, causing the indoor alarm 5 to issue an alarm.

When this alarm is known and the drain in the fuel tank 1 is removed, the drain float 15 descends and the sensor operating body 14 separates from the sensor 7, returning to its original state and canceling the alarm.

〔Example〕

Sensors 6, 7 Sensor movable bodies 13, 14
Figure shows a case where a reed switch and magnet are used.

The alarm 5 has a built-in battery in a case 16, and has a confirmation lamp 17, a buzzer 18, a changeover switch 19, and a test button 20 on its surface.The alarm 5 and sensors 6 and 7 are made of oil-resistant material. ,
Heat-resistant conductive wires 21 and 25 are connected by a connector 24 to facilitate indoor and outdoor wiring.

In the figure, reference numeral 23 is a pin, 26 is a heater, and 27 is a transportation pipeline.

[Effect of idea]

Since the present invention is configured as described above, it exhibits the following features.

1. Since the pointer 4 is rotated by the twisting of the rotating plate 9 penetrated through the through hole 12' of the float 12, the indicating operation of the pointer 4 is performed accurately, and the current amount can be checked with the pointer 4 at any time. You can accurately check the amount of lubrication when refueling.

2. One of the two guide rods 10, 11 is formed into a pipe, and the sensors 6, 7 are installed inside this pipe.
Therefore, if a reed switch is used for the sensors 6 and 7, even if a spark is generated during switching, it is carried out within the pipe, so there is no risk of igniting the oil, making it extremely safe.

3 The sensors 6 and 7 are arranged in two stages, upper and lower, within the guide rod 10 made of a single pipe, and the upper sensor 6 is connected to the sensor movable body 13 provided on the float 12.
The lower sensor 7 is activated by the sensor movable body 14 of the drain float 15 to alert that drain has accumulated at the bottom of the tank, and the floats 12 arranged above and below Since both drain floats 15 are prevented from further lowering and rising by the connecting body 22, both of them can accurately maintain their alarm positions.

4 Lead wires 21 and 25 of sensors 6 and 7 are connection wire 2
4, it is extremely easy to install the fuel tank 1 outdoors and the alarm 5 indoors.
