Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cleaning method and an apparatus for cleaning an elevated water tank in a building or the like without interrupting the water supply for domestic use.

Traditionally, when cleaning elevated water tanks in buildings, etc.,
Water is always cut off for 1 to 1.5 hours, and this is said to be a factor that makes residents and owners of healthy animals hesitant to carry out cleaning work on elevated aquariums. There is.

One object of the present invention is to provide a method and apparatus for cleaning an elevated water tank, which eliminates the above-mentioned drawbacks of conventional cleaning methods and eliminates the need for water supply interruptions.

Embodiments of the invention will be described with reference to the drawings. 1st
The figure shows saddle water distribution valves 5 installed in the water intake pipe 3 and water lift pipe 4 around the water receiving tank 1 and water supply pump 2, respectively, and an air release valve 15 installed in the middle of the bypass piping (1) 6 that connects the water distribution valves. The figure shows a state in which a temporary water pump 7 and a high-pressure tank 8 are connected.

The installation location of the saddle distribution faucet 5 to the suction pipe 3 side is the suction side close 11 - the intermediate part between the valve 9 and the water tank 1, and the installation location of the saddle distribution faucet 5 to the pumping pipe 4 side is as follows. Discharge side closed 11 - This is the discharge side of the valve 10.

When carrying out cleaning, the existing water supply pump 2 is set to IL, the suction side is closed 11; the discharge side is closed 11 and the valve 10 is closed, the two saddle water faucets 5 are opened, and the temporary water pump 7 is operated. pump water. After the start of operation, the air in this pipe is vented using the air vent valve 11.

In Figure 2, a saddle branch faucet 5 is installed in each of the water supply pipes 13 connected to the water pump 4 and the elevated water tank 12'G, and a bypass pipe f2J161 connecting the two faucets is connected to an air bleed valve 11. A state in which the water intake valve 17 is connected is shown.

The positions of the saddle branch faucet 5 are as follows: one is from the pumping close 11 of the elevated water tank 12 to the inlet water pumping pipe 4 of the valve 14, and the other is from the water supply closing 11 of the elevated water tank 12 to the outlet water pipe 13 of the valve 15. Each of them can write a few poems.

Prior to the start of operation of the temporary water pump 7, close the pumping close valve 14 and the water supply close valve 11-15 of the elevated water tank 12, open all the saddle water valves 5, and also open the air bleed valve 11. Air bleed valve 11 closes after air bleed is completed! 1-
do.

With the above operations, switching between pumping and water supply is completed, so the elevated water tank can be cleaned without interruption of domestic water supply.

FIG.

It is towed by a special cleaning vehicle, cut off on site, and transported to the vicinity of the water tank, so that it can be cut off on site and transported to the vicinity of the water tank. 18, so that the necessary power source etc. can be secured at the site.

The trolley 19 is equipped with a coupler section 20 for connecting to a special washing vehicle and a folding i+J function freestanding stand 2I with a star.
Since it is an ffi type, it is easy to turn around and can be transported close to the water tank. A special cleaning vehicle will be used to clean the inside of the elevated water tank.

By implementing the present invention, the following effects are brought about compared to conventional methods and devices.

(1) By using a temporary water pump, it becomes possible to clean the elevated water tank without cutting off the customer's water supply. Problems such as hesitation will be resolved.

(2) The setup work for switching the water supply can be carried out while the water supply continues by installing the saddle water faucet, so there is no water outage due to cleaning.

(3) The above-mentioned saddle water faucet is a system that can be used as is for the second and subsequent cleanings, so the cost required for the first cleaning will be 2R as it includes the setup necessary for switching. It can be said that it is economical to reduce the cost by considering it from [Run 1] onwards.

(4) Since the temporary water pump and the FK source power generation crosspiece are two-way, it will be easy to handle the ground water tank, etc., and efficient work with good maneuverability can be expected. The suction capacity of a water pump is usually 6 to 7 m, so it can be considered that the suction capacity is limited during cleaning, but this problem can be solved by making it portable.

Claims (1)

[Claims] 1. Saddle branch faucets are provided on the suction pipe side and the lift pipe side of the existing water supply pump, respectively, and a temporary water pump high-pressure tank is connected between the two equally divided faucets. Furthermore, saddle distribution valves are provided on the lift pipe side and the water supply pipe side of the elevated water tank, respectively, and the distribution valves are connected by bypass piping. How to clean an elevated aquarium without water outage by installing temporary piping like my son did. 2. A device that cleans an elevated water tank without water outages by mounting a temporary water pump and high-pressure tank on a trolley that can be towed, and installing a power generation crosspiece as a power source for the second-class crosspiece.
