Description

[Detailed explanation of the invention] This invention relates to an elevated water tank installed on the roof as a building water supply system.The purpose of this invention is to make it a two-tiered tank, which is superior in terms of structure, construction, and cost. It's about providing something.

Conventionally, elevated water tanks installed on rooftops as water supply equipment for high-rise condominiums, etc., have adopted a gravity pressurization system, so in order to maintain water pressure on the top floor (required pressure height:
H) It was not possible to install an aquarium directly under the roof, so it was common to build a pedestal and place the aquarium on it, as shown in Figure 3.

Therefore, a large water tank with the capacity of the entire building had to be installed on top of the pedestal.

For this reason, the frame had to be structurally large, and the area it occupied had to be large.

This invention was devised to solve the above-mentioned conventional problems, and will be explained below based on the illustrated embodiment.

1 indicates the upper tank, and 2 indicates the lower tank.The tank is made of steel plate or other material that can withstand water pressure and its own weight, and is made of a single plate of other material that satisfies the needs. Depending on the case, reinforcing material is inserted into the inner or outer surface, and the upper and lower sections are integrally formed.

The upper tank 1 and the lower tank 2 are communicated with each other by a communication pipe 3, and the communication pipe 3 maintains a predetermined height in the upper tank 1.

Further, in the upper part of the upper tank 1, a distal end portion of a water pump 5 is inserted, which communicates with a water pump 4 installed below.

In addition, three control electrode rods 6, 7 are placed in the upper tank 1 from the top.
．． 8 is hanging down.

The lower end of the control electrode rod 6 is located in the lower part of the tank (level: ao), the lower end of the control rod 7 is located in the middle part of the tank (level: al), and the lower end of the control rod 8 is located in the middle part of the tank (level: ao). is the upper part of the tank at the same level as the upper end of the connecting pipe 3 (level:
a2).

On the other hand, in the lower tank 2, three water level control electrode rods 9, 10, 11, and 12 are suspended from the upper part.

The lower end of the electrode rod 9 is positioned at the lower part of the tank (level: b).

), the lower end of the electrode rod 10 is located in the middle part of the tank (level: bl), the lower end of the electrode rod 11 is located in the upper part of the tank (level: b2), the lower end of the electrode rod 12 is located in the tank A level located further above: b3) This level is provided at the same level as the lower end of the communication pipe 3.

Further, a spout 13 for overflow is provided on one side of the lower tank 2 at approximately the same level as the electrode rod 12 .

This device has the above-mentioned configuration, and when in use, first, when the water level in the lower tank 2 falls below b1, the pump 4 is started and water is injected into the upper tank 1, and when the water level reaches the full level of the upper tank 1 or higher, an overflow occurs. Water is supplied to the lower tank 2 through the connecting pipe 3, and when the lower tank 2 becomes full, the water pump 4 stops at the b2 level.

Next, when the water level in the upper tank 1 reaches 31 or higher, the water pump 4 is started and water is poured into the upper tank 1, and when the upper tank 1 is full, water is supplied to the lower tank 2 through the connecting pipe 3 in the form of an overflow. When the water level reaches b2, the water pump 4 stops and water supply ends.

In the unlikely event that water pump 4 does not stop, level B
3 full limit alarm is activated, and if it exceeds the limit, water is spouted from the discharge port 13 as a form of overflow.

By being automatically operated in this manner, the upper tank 1 supplies water to the upper floor, and the lower tank 2 supplies water to the lower floor, as shown in FIG.

As mentioned above, this idea is a two-tiered elevated water tank installed on the rooftop used in the gravity water supply system of building water supply equipment, and since the upper water tank is located at a high position, it can be used on the upper floors of the building. The required water pressure for water supply can be maintained, and the lower water tank is used for water supply for the other lower floors.
By integrating the two, (a) there is no need for the conventional mount installed to obtain water pressure, (b) the area occupied is smaller than that of a conventional aquarium, and (c) it is aesthetically sleek. (d) Construction is simplified by saving the trouble of assembling the frame, (e) Construction safety is expected, (f) When cleaning the inside of the tank regularly, It has many advantages, such as being easy to clean so there is no water outage, and (g) construction costs are lower than conventional methods.
