Description

[Detailed description of the invention] Industrial application field This invention uses a connection cap that allows wiring to be attached and detached from the holder of the electrode rod, which is used to detect the water level in the aquarium, control pumps, etc., and issue alarms when checking the aquarium. This invention relates to a mechanism that makes it possible to change the wiring.

Conventional technology Detects the water level in water tanks, elevated water tanks, etc. and controls the liquid level (starting/stopping pumps, full water alarm, low water alarm, etc.)
In this case, as shown in FIG. 10, an electrode holder 02 equipped with a plurality of electrode rods 01 of different lengths is attached to a water tank 03.

As shown in FIG. 11, the electrode holder 02 connects the terminal 04 of the electrode rod 01 and the cable 05 to
Combine by. In FIG. 11, 07 is a drip-proof cover, and 08 is an electrode holder. In addition, if the flow is fast or there are large waves due to water purification, etc., install a breakwater pipe around the electrode rod.

Problems that the invention aims to solve According to the conventional technology mentioned above, the connection between the electrode rod and the wiring cable is screwed (fixed type), so it is difficult to confirm the performance of the aquarium equipment when it is completed or after delivery. When checking the control system, it is necessary to move water in and out of the tank to vary the water level.

Measures to solve the problem By configuring the connection between the electrode rod and control wiring to be removable and changing the connection between the electrode rod and control wiring depending on the water level to be checked, it is possible to simulate the upper and lower water surfaces. This makes it possible to test the functions of control panels, etc.

Function At the time of completion inspection and periodic inspection, water is normally stored up to the normal water level, so the full water alarm is checked by stacking the connection cap at the full water level on the ground terminal at this normal water level. Also, by disconnecting the connection cap at the low water level, the low water alarm is checked.

In this way, the full water alarm, low water alarm, etc. can be checked without causing water to flow in or out of the aquarium.

Embodiment In FIGS. 1 to 6, 1 is a plurality of electrode rods having different lengths, 2 is an electrode holder that supports the electrode rod 1, 3 is an upper terminal of the electrode rod 1, and 4 is a ground connection cap. , 5 is the insulation coating of the connection cap 4, 6
is a conductive grip of the connection cap 4, 7 is a flexible support part of the conductive grip 6, 8 is a check terminal connected to the conductive grip 6, 9 is an insulating cap for curing the check terminal 8, and 10 is a connection caps for water level and full water level; 11 is the insulation coating of the connection cap 10; 12 is the conductive grip of the connection cap 10; 13 is the flexible support of the conductive grip 12; 14 is the cable of the connection caps 4, 10; 1
5 is an upper structural member of the water tank 16, and 17 is a drip-proof cover of the electrode holder 2.

In such equipment, during normal use,
As shown in FIG. 7, the ground connection cap 4, the low water level connection cap 10 _-1 and the full water level connection cap 10 _-2 are connected to the upper terminals 3 in order from the longer end of the electrode rod 1.

Each connection cap 4, 10 _-1 , 10 _-2 is connected via a cable 14 to a control position (not shown). Check terminal 8 of earth connection cap 4
An insulator cap 9 is attached to the terminal 8 to protect the terminal 8.

In addition, each water surface in FIG. 7 is controlled as follows.

High water level: Warning when water level exceeds.

Normal water level: Normally at the time of completion inspection and periodic inspection,
It is at constant water level.

Low water level: Warning when water level drops.

When checking the full water alarm, as shown in Figure 8, remove the full water level connection cap _10-2 from the upper terminal 3 of the full water level electrode rod, and connect the insulator cap 9 from the check terminal 8 of the ground connection cap 4.
, and connect the full water level connection cap _10-2 to the check terminal 8.

When checking the low water level alarm, as shown in Fig. 9, connect the ground connection cap 4 and the high water level connection cap _10-2 to the respective electrode rods 1 as in normal use, and connect the low water level connection cap 10
_-1 from its upper terminal 3.

The above embodiment shows the case of 3P, but in the case of 4P,
For 5P, use the same operation as for 3P.
It is possible to check each case.

For 3P: Full water alarm/low water alarm.

For 4P: Full water alarm/low water alarm. Prevents pump from idling.

For 5P: Full water alarm/low water alarm. Start pump.
Pump stopped. Prevents pump from idling.

Effects of the invention It is possible to check full water alarms, low water alarms, etc. at the constant water level without draining the water in the aquarium, and to check full water alarms, low water alarms, etc. without increasing or decreasing the water in the aquarium. It becomes possible to perform simulations.
