Abstract

PURPOSE:To utilize single conveying pump for multi purposes by enabling exchange of suction port of high pressure pump to each suction port communicating with water storage tanks at the inside and outside of system while the delivery port to the high position delivery port and each conveying path of injection nozzle. CONSTITUTION:It is constructed such that the suction port 3 of high pressure pump 1 to be driven by motor 2 can be opened while exchanging between suction port 3a led down into an inner storage tank 4a and suction port 3b led down into outer storage tank 4b through exchange operation of three-way cock. The delivery port 7 of high pressure pump 1 can be opened freely to both or any one conveying path 8a, 8b of high position delivery port 7a and injection nozzle 7b through exchange operation of three-way cock. Furthermore, a water supply port 9 to be coupled with water supply conduit 10 is provided to inner storage tank 4a. Consequently, water supply to high position delivery port 7a, spray, fire extinguish, cleaning etc. through nozzle 7b can be performed by means of single conveying pump.

Description

[Detailed description of the invention] (1) Purpose of the invention The present invention relates to a water conveyor.

Conventionally, a dedicated water supply device has been used to supply water to buildings, etc., and this device cannot be used for general purposes.

An object of the present invention is to have a single water supply machine perform a multipurpose water supply function.

(2) Development of the invention In the water conveyor according to the present invention, the water suction valve of the high pressure pump is
fr-The structure is designed so that it can be opened by switching the water intake into the on-board water storage tank and the water intake into the external water storage tank, and the high-pressure bonder discharge port can be connected to the high-place pumping water discharge port and the water intake into the external water storage tank. The structure is such that it can be opened to a water supply channel to either or both of the injection nozzles, and the in-flight water storage tank is provided with a water supply port connected to a water supply source.

To explain the south side of the example, 1 is electric! A high-pressure pump 8 is driven by the machine 2, and 8 is a water inlet of the high-pressure pump l. For example, by switching a three-way cock, etc., the water inlet 8a is introduced into the in-flight water storage tank 4a, and the water inlet 8a is connected to the outside of the machine. It is structured so that it can be opened by switching to the water intake port 8b which is lowered into the water storage tank 4b. 5a is a strainer attached to the water intake port 8a, and 15b is a strainer attached to the water intake port 8b. Reference numeral 6 denotes a water intake conduit that completely connects the pump water intake port 8 and the water intake port 8b inside the water storage tank outside the machine, and is connected by a coupling. It is connected so that it can be removed when in use. Reference numeral 7 denotes a discharge port of the high-pressure pump 1, which can be opened to a water supply channel to either or both of the high-place pumping discharge lower a and the injection nozzle (771) by, for example, switching the three-way cock. It is structured so that you can get it. 8a is a water supply pipe connecting the pump discharge lower and the elevated water pumping discharge lower a, 8b is a water supply pipe connecting the pump discharge lower and the injection nozzle 7b, and both of these pipes can be attached and removed by couplings. It has a flexible connection structure. Reference numeral 9 denotes a water supply port for supplying tap water to the in-flight water storage tank 4a, and is connected to a water tap via a water supply conduit 1O. 11 is a water level detection device installed in the in-flight water storage tank 4a, 12 is an electromagnetic switch installed in the upper part of the in-flight water storage tank 4a, 18 is a pressure switch attached to the pump discharge lower,
Reference numeral 14 denotes wheels for movement attached to the outside of the bottom of the in-flight water storage tank 4a.

Elevated water pumping and discharging lower a... installed on each floor of a building, etc.
・When using tap water to supply water to the water supply channel to L/'Ib (7a, injection nozzle), high-pressure pump I'eg is supplied to the in-flight water storage tank 4a through the water supply conduit 10 connected to the water tap. Move the water intake port 8 in the onboard water storage tank.
The water sucked into the pump water intake port 3 from a is sent from the pump discharge lower to a predetermined water supply channel. If the water discharged from the pump discharge lower is directed to the water supply conduit 8a, the water will be sent to the high-place pumping discharge lowers a...7a, and water will be supplied to each floor such as 7a and 7a. In addition, if the water discharged from the pump discharge lower is directed to the water supply conduit 8b, the injection nozzle)
Spraying water, extinguishing fires, cleaning, etc. can be performed with L/7b, so spray nozzle l'! It is desirable to replace b with one suitable for each purpose.

When using water from the non-bond water storage tank 4b, pump dazzling water 8
The water suction conduit 6 is connected to the high-pressure pump 1, and the high-pressure pump 1 is moved, and the water sucked into the pump water intake port 8 from the water intake port 8b in the external water storage tank is sent from the pump discharge lower to a predetermined water supply channel. The ability to send water to the high-place water pumping and discharging lower a...7a or to inject it from the injection nozzle 7b is the same as when tap water is used.

(8) Effects of the Invention According to the present invention, in addition to feeding water to the high-place water pumping and discharging lower a...7a, water sprinkling, fire extinguishing, and cleaning operations using the nozzle 7b can be easily performed using one water feeder. It is possible. Moreover, it is extremely convenient because either the water supply or the external water storage tank 4b can be used as the supply liquid source.
