Description

Technical Field

[0001] The utility model relates to the field of outboard motor testing, in particular to an emergency stop control device for an outboard motor testing pool. Background Art

[0002] With the rapid development of the domestic and international boating industry, the demand for boats is growing year by year. As outboard motors undergo development, testing, and reliability verification, they often require simultaneous control of two or even four outboard motors. To mitigate the safety risks associated with simultaneous outboard motor startup and protect personnel, a device is required to simultaneously shut down the engines in an emergency.

[0003] Because the existing test tank for outboard motor commissioning verification tests often encounters multiple machines running simultaneously and an uncontrolled emergency shutdown, the machine operation commissioning tank presents various safety hazards. On-site staff calibrate various engine operating parameters and read data, which requires high speed and load operations, posing a significant safety hazard. To address this safety issue, the machine ECU control line must be used to uniformly control the emergency stop button while the engines are running simultaneously. In the event of a major safety hazard to the machine or personnel, an emergency stop control can be used to stop the machine in a timely manner, avoiding major safety accidents. Utility Model Content

[0004] The utility model aims to provide an emergency stop control device for an outboard motor test tank, which improves and controls the emergency stop control unit through the outboard motor's own protection emergency stop line, and integrates the configuration control into a unified line control.

[0006] Emergency stop control device for outboard engine test tank, including:

[0007] AC power supply line, inputs AC power to the switching power supply UR1;

[0009] Intermediate relays KA1, KA2, KA3, and KA4 are connected in parallel between the positive and negative poles of the DC output of the switching power supply UR1; the normally open contacts of the intermediate relays KA1, KA2, KA3, and KA4 are connected in series with the emergency stop lines of the four outboard motors;

[0010] The emergency stop button SB1 is connected in series between the positive pole of the DC output of the switching power supply UR1 and each intermediate relay.

[0011] Preferably, the intermediate relays KA1, KA2, KA3, and KA4 are respectively connected in parallel with indicator lights HL1, HL2, HL3, and HL4 to indicate the power-on status of the relays.

This configuration and control are integrated into a unified circuit for easy switching and installation. Based on test tank testing, the control circuit is routed, and an emergency stop button is installed in the control unit's power supply circuit to control the relay power supply. When the emergency stop button is pressed, the emergency stop lines of multiple outboard motors are disconnected, shutting down the motors.

In the event of an emergency, multiple outboard motors can be quickly stopped, effectively preventing injuries from the operation of the motors. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0017] Figure 1 This is a schematic diagram of the emergency stop control device for an outboard motor test tank according to the present invention;

[0018] Figure 2 The figure is a schematic diagram of the arrangement of the emergency stop control device for an outboard motor test tank according to the present invention. DETAILED DESCRIPTION

[0019] The present invention utilizes a control circuit based on test tank testing. An emergency stop button is installed in the control unit's power supply circuit to control the relay power supply. The four outboard motor emergency stop lines are connected to the four normally open contacts of the relays. The outboard motor's emergency stop is normally closed. When the relay coils are energized, the normally open contacts close, putting the outboard motor's emergency stop in an on-state state and enabling normal operation. Pressing the emergency stop button disconnects the button's normally closed state and disconnects the circuit power supply. The four relay coils of the intermediate relay lose power, opening their normally closed contacts. This disconnects the outboard motor's emergency stop line, causing the motor to shut down.

[0020] like Figure 1 、 2As shown, the emergency stop control device for an outboard motor test tank includes an AC power supply line, a circuit breaker QF1, a switching power supply UR1, fuses FU1 and FU2, an emergency stop button SB1, intermediate relays KA1, KA2, KA3, and KA4, and indicator lights HL1, HL2, HL3, and HL4. The specific connections are as follows.

[0021] The AC power supply line inputs AC power to the switching power supply UR1, and a circuit breaker QF1 is connected in series to the AC power supply line.

[0022] Switching power supply UR1 converts AC power into 24V DC power.

[0023] Intermediate relays KA1, KA2, KA3, and KA4 are respectively connected in parallel between the positive and negative poles of the DC output of the switching power supply UR1; the normally open contacts of the intermediate relays KA1, KA2, KA3, and KA4 are respectively connected in series with the emergency stop lines of the four outboard motors; the intermediate relays KA1, KA2, KA3, and KA4 are respectively connected in parallel with indicator lights HL1, HL2, HL3, and HL4 to indicate the power-on status of the relays.

[0024] The emergency stop button SB1 is connected in series between the positive pole of the DC output of the switching power supply UR1 and each intermediate relay.

[0025] The positive and negative poles of the DC power output by the switching power supply UR1 are respectively connected in series with fuses FU1 and FU2.

[0026] During operation, circuit breaker QF1 is closed to supply 24V switching power supply UR1, which then powers the entire control circuit through fuses FU1 and FU2. At this point, the normally closed contacts of emergency stop button SB1 supply power to four intermediate relays (KA1, KA2, KA3, and KA4), energizing them. Four indicator lights HL1, HL2, HL3, and HL4 indicate relay power. Lighting indicates energized relays, while off indicates disconnected. The four outboard motor emergency stop lines are connected to the normally open contacts of four corresponding relays (the outboard motor's emergency stop is normally closed). Because the relay coils are energized, the normally open contacts close, activating the outboard motor's emergency stop function and allowing normal operation. Pressing emergency stop button SB1 disconnects the normally closed contact and disconnects the circuit power. The coils of the four intermediate relays KA1, KA2, KA3, and KA4 are de-energized, and their normally closed contacts open. This disconnects the outboard motor's emergency stop line, shutting down the motor. Resetting emergency stop button SB1 restores the outboard motor to its original state.

[0027] By adopting the above-mentioned debugging pool safety control method, the control harness is easy to install through quick connection, and it can realize that when multiple outboard motors are running at the same time, in case of emergency, multiple outboard motors can be quickly responded to and controlled to stop running at the same time, effectively avoiding harm caused by the operation of the machines.

[0028] The above embodiments are intended only to illustrate the technical concepts and features of the present invention. Their purpose is to enable those familiar with the art to understand the contents of the present invention and implement them accordingly. They are not intended to limit the scope of protection of the present invention. Any modifications based on the spirit of the main technical solution of the present invention shall be included in the scope of protection of the present invention.
