Abstract

PURPOSE:To conduct automatic management of start/stop of an engine pump so as to realize rationalization and labor saving in a portable automatic operative engine pump by providing a pressure sensor, a temperature sensor, a humidity sensor and a timer switch. CONSTITUTION:A self-priming pump 2 is directly coupled to an engine 1. A pipe line of a delivery port 4 is provided with a pressure sensor or temperature sensor, a humidity sensor, a timer switch and the like, and those various sensors can be changed according to objects of use. When a start button in a control box 8 is pressed, the engine is started and simultaneously the pump 2 is started to start water supply. When pressure in the pipe line becomes lower than a specified value, the pressure sensor 5 senses abnormality to issue a command to the control box 8 and controls speed of the engine 1 to simultaneously adjust pump pressure. When the pipe line is completely closed, the pressure sensor 5 issues a stop command to the control box 8 to stop the engine 1. Thus, rationalization as well as labor saving can be realized.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable automatic operation engine pump which can move freely.

[0002]

2. Description of the Related Art Up to now, automatic pumps of this kind using commercial electric power have been used. However, there is no engine pump of this specification.

[0003]

There has been no engine pump in which an engine pump is installed in a place where electric power is not installed and the pump is arbitrarily stopped when pumping water is not needed.

[0004]

[Means for Solving the Problems] A pressure sensor, a temperature sensor, a humidity sensor, and a timer switch are installed in an engine pump, and when a freely set number is reached, the number is detected and the engine is automatically controlled by starting and stopping the engine with an electronic signal. It can contribute to rationalization and labor saving.

[0005] In the construction site where power transmission is not possible, away from the house, when pumping water for pumping water in a mountainous remote area, there is no choice but to rely on an engine pump. At that time, the work of starting and stopping the engine pump is very difficult and requires time. By automatically operating the pump and stopping it, the purpose of pumping water can be achieved.

The present invention provides a portable automatic operation pump developed for smoothly performing pumping and water feeding work in a place where it is difficult to secure a power source.

[0007]

[Operation] For this purpose, a pressure sensor, temperature sensor, humidity sensor, and timer switch are connected to the discharge side of the portable automatic operation engine pump, and when the designated numbers are reached, the engine pump is automatically started and stopped.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS [FIG. 1] A portable automatic operation engine pump of the present invention will be described with reference to the accompanying drawings. In FIG. 1, reference numeral (1) is an engine, (2) is a self-priming pump directly connected to the engine, (3) is a suction port of the pump, and (4) is a discharge port of the pump. (5) is a pressure sensor or temperature sensor attached to the discharge line
Humidity sensor It is a timer switch, and each sensor can be changed according to its purpose of use. This is for operating the control box of (7) with the power source for starting the engine pump of (6). Connect the discharge pipe to the suction pipe (4) to (3), and press the start button in the control box of (8) to the portable automatic driving engine pump that was transported to a predetermined location by a tractor or a carrier. (1) The pump is started and water supply is started. When the pressure in the pipeline is constant, the pump in (2) continues pumping water, but when the pressure in the pipeline rises or falls, the pressure sensor in (5) senses an abnormality and commands the control box in (8). By controlling the rotation speed of the engine pump of (1), the pump pressure of (2) is adjusted. When the pipeline is closed for a while, (5) a stop command is issued to the control box of the pressure sensor (8) to stop the engine pump (1).
Similar control is possible even when the temperature sensor, humidity sensor, and timer switch are stopped.

The accompanying drawings are side views of a portable self-driving engine pump according to the present invention, which will now be described. In FIG. 1, reference numeral (1) is an engine, (2) is a self-priming pump directly connected to the engine, (3) is a suction port of the pump, and (4) is a discharge port. (5) is a pressure sensor or a temperature sensor, a humidity sensor, a timer switch, etc. attached to the discharge line, and various sensors can be changed depending on the purpose of use. (6) is a starting power source for the engine, and is for activating the control box of (7). Due to the command of (5), (7)
Control box starts or stops. The water suction pipe is connected to the suction port of (3) and the drain pipe is connected to the discharge port of (3) of the portable automatic engine pump transported to a predetermined position by a tractor or a carrier.
When the start button in the control box of (8) is pressed, the engine of (1) is started, and at the same time, the pump is started and water supply is started. When the pressure in the pipeline is the specified pressure and the pressure is constant, the pump continues pumping water. When the pressure in the pipeline falls below the specified pressure, the pressure sensor in (5) detects an abnormality and issues a command to the control box in (8). (1) Controls the engine speed and simultaneously (2) Pumps. Pressure is adjusted. When the pipe line is completely closed, a stop command is issued to the control box of the pressure sensor (8) of (5) to stop the engine of (1). The same control can be applied to the operation of the temperature sensor, humidity sensor and timer switch.
