Abstract

(57) [Summary] [Purpose] The operation surface of a manual submersible pump is achieved by separating the automatic control circuit from the submersible pump body and integrating the device (unitization) while maintaining the low price / startability of the manual submersible pump. The purpose is to save labor and improve work efficiency. [Structure] Automatic control start / stop detector [A] (float switch or electrode, etc.) and power supply connection [B] (AC power outlet connection) and submersible pump connection outlet / power supply unit body [C] ( Transformers for control circuits, pumps, etc. Connection outlets, diodes
A switch, power supply indicator, relay, fuse, etc., are configured in a circuit and integrated (unitized).

[Industrial applications]

 General-purpose portable hand-operated submersible pumps are widely used in various fields in the industry due to their good startability (there are no accessories for automation in the main body / and they are low cost). I will. By taking advantage of the advantages of this submersible pump, which is startable and low-priced, and by connecting the automatic control unit of the present invention without any modification to the body, a manual submersible pump, etc. can be easily installed anywhere. Can be automated. By this automation, it is possible to improve efficiency / labor saving of work in various industrial fields currently used (construction drainage, rainwater spring drainage, industrial drainage, irrigation, etc.). ..

[Prior Art]

 Generally, automated submersible float-equipped submersible pumps etc. have impaired motility in the parts attached to the main body (float switch, float support pipe, control circuit box, etc.), and manual submersible pumps are difficult to operate. We were unable to save labor, and both had problems.

[Problems to be solved by the device]

 While keeping the low price / startability of the manual submersible pump, by separating the automatic control circuit from the submersible pump main unit and integrating the device (unitization), labor saving in the operation side of the manual submersible pump and work efficiency For the purpose of

[Means for Solving the Problems]

 The basic configuration of this invention is to include an automatic control start / stop detector [A] (float switch or electrode, etc.), power supply connection [B] (AC power outlet connection), and submersible pump connection outlet. A circuit configuration consisting of a power supply unit main body [C] (built-in control transformer transformer / pump connection outlet, diode, switch, fuse, relay, indicator light, etc.), etc. Installed at the same level as the injection position (position not affected by suction) By using the above settings, the [A] part detects the water level and automatically controls (stops or starts) the pump, etc. It is an integrated (unitized) version of the circuit configuration. (The float switch shall be equipped with an anchor part, and part [A] shall include the case where multiple float switches or electrodes are used for automatic operation.)

【Example】

 Figures 1 and 2 show the sequence circuit drawing of the present invention, and Figure 3 shows an example photograph of this device. Figure 1 shows an example of using a b-contact float switch for the automatic control start / stop detector [A]. By using a b-contact float switch, the circuit is configured so that the float that is normally in water (float rises in water) is de-energized and when drainage is complete (float descends), the relay is activated. Therefore, when the pump is operating, the control circuit (AC / DC12V) can be controlled in the non-energized state, and safety can be improved (the contact point configuration inside the float switch is open when float rises [OFF] and closes when fall The switch [SW] of the power supply unit body is automatically activated when turned ON (closed), and forcedly operated when turned OFF (open)). The second figure shows a unit using a normal floatless control circuit. The right end [A] ′ in Figs. 1-2 shows an example of circuit configuration that enables automatic operation using multiple float switches or electrodes.

[Effect of the device]

 By using this unit, automation can be performed without compromising the merit (startability / low price) of a manual submersible pump, saving labor in operation and improving work efficiency.
