Description

Technical Field

[0001] This utility model relates to the field of controller technology, specifically an overload automatic power-off controller. Background Technology

[0002] A controller is a master control device that controls the starting, speed regulation, braking, and reversing of a motor by changing the wiring of the main circuit or control circuit and changing the resistance value in the circuit according to a predetermined sequence. With the advancement of science and technology and the continuous changes in market demand, controllers with automatic overload power-off functions have gradually entered the market.

[0003] However, traditional overload automatic power-off controllers can only cut off the power to the circuit when there is an overload. Since the power is cut off, the alarm cannot be powered and the alarm cannot be triggered. Therefore, it cannot promptly alert the staff, which is not conducive to practical application and operation.

[0004] Therefore, those skilled in the art provide an overload automatic power-off controller to solve the problems mentioned in the background art. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an overload automatic power-off controller, which solves the problem mentioned in the background technology that traditional overload automatic power-off controllers can only control the circuit to cut off power when there is an overload. Since the circuit is cut off, it is impossible to power the alarm and perform the alarm operation, thus failing to promptly remind the staff.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an overload automatic power-off controller, comprising a control box, wherein the control box has a first slot and a second slot inside, an electromagnet is fixedly installed on the inner wall of the first slot away from the second slot, an overload protection circuit breaker is installed on the top of the control box, the overload protection circuit breaker is electrically connected to the electromagnet via a wire, a conduction component is provided inside the control box, and an alarm component is provided on the outside of the control box, the conduction component is used to conduct the normal operating circuit when the electromagnet is energized, and to conduct the alarm component when the electromagnet is de-energized.

[0007] The above technical solution involves setting up an overload protection circuit breaker, an electromagnet, and a conducting component. The electromagnet attracts the conducting component. When the overload protection circuit breaker detects an overload, it cuts off the power to the control circuit, thereby de-energizing the electromagnet. This causes the conducting component to shift, automatically activating the alarm component when the circuit is de-energized. This allows the equipment to automatically control and switch to activate the alarm component when the circuit is broken, providing timely alarms and alerting staff, which is beneficial for practical application and operation.

[0008] Preferably, the conductive assembly includes an iron plate, a connecting rod, a movable plate, a spring, a conductive rod, and a notch. The iron plate is slidably connected inside the first slot. The connecting rod is fixedly connected to one side of the iron plate. The end of the connecting rod away from the iron plate extends into the second slot and is fixedly connected to the movable plate. The movable plate is slidably connected inside the second slot. The spring is sleeved on the outside of the connecting rod and located between the inner wall of the second slot and the movable plate. The conductive rod is embedded inside the movable plate. The notch is opened on the side of the control box away from the first slot.

[0009] With the above technical solution, when the movable plate moves inside the second slot, it can drive the iron plate to move inside the first slot via the connecting rod. Simultaneously, utilizing the spring force, the movable plate, connecting rod, and iron plate can be controlled to return to their original positions when the electromagnet is de-energized.

[0010] Preferably, the alarm assembly includes a third terminal, a battery, a fourth terminal, and an alarm. The third terminal is installed at the bottom of the control box away from the electromagnet, and the battery is electrically connected to the third terminal. The fourth terminal is installed at the top of the control box away from the electromagnet, and the alarm is electrically connected to the fourth terminal.

[0011] The above technical solution utilizes a storage battery for power, thereby energizing the alarm and enabling it to function when the third and fourth terminals are connected.

[0012] Preferably, a first terminal block is fixedly installed at the bottom of the control box, and a second terminal block is fixedly installed at the top of the control box. The second terminal block is electrically connected to the overload protection circuit breaker via a wire.

[0013] Preferably, the first terminal, the second terminal, the third terminal, and the fourth terminal are all used in conjunction with a conductive rod.

[0014] The above technical solution allows for better connection of the first and second terminals using a conductive rod, and also enables better connection of the third and fourth terminals.

[0015] Preferably, both the control box and the movable plate are made of insulating material.

[0016] The above technical solution facilitates insulation operations.

[0017] This utility model provides an automatic overload power-off controller, which has the following beneficial effects: This overload automatic power-off controller uses an overload protection circuit breaker, an electromagnet, and a conducting component. The electromagnet attracts the conducting component. When the overload protection circuit breaker detects an overload, it cuts off the power to the control circuit, causing the electromagnet to de-energize. This displacement of the conducting component allows it to automatically activate the alarm component when the circuit is de-energized. This enables the equipment to automatically control and switch to activate the alarm component when the circuit is broken, and to promptly issue an alarm to alert staff, which is beneficial for practical application and operation.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] Reference Figures 1-4 This utility model provides an overload automatic power-off controller, including a control box 1. The control box 1 is made of insulating material for easy insulation operation. The control box 1 has a first slot 2 and a second slot 3 inside. An electromagnet 4 is fixedly installed on the inner wall of the first slot 2 away from the second slot 3. An overload protection circuit breaker 5 is installed on the top of the control box 1. The overload protection circuit breaker 5 is electrically connected to the electromagnet 4 via a wire. When the overload protection circuit breaker 5 detects a circuit overload, it breaks the circuit, thereby de-energizing the electromagnet 4 and causing it to lose its magnetism. A first terminal 11 is fixedly installed at the bottom of the control box 1 for connection to external electrical equipment. A second terminal 12 is fixedly installed on the top of the control box 1, and the second terminal 12 is electrically connected to the overload protection circuit breaker 5 via a wire for easy wiring.

[0025] In one aspect of this embodiment, a conductive component is provided inside the control box 1, and an alarm component is provided outside the control box 1. The conductive component is used to conduct the normal operation circuit when the electromagnet 4 is energized, and to conduct the alarm component when the electromagnet 4 is de-energized.

[0026] The conductive assembly includes an iron plate 6, a connecting rod 7, a movable plate 8, a spring 9, a conductive rod 10, and a notch 17. The iron plate 6 is slidably connected inside the first slot 2. The connecting rod 7 is fixedly connected to one side of the iron plate 6, with one end extending away from the iron plate 6 into the second slot 3 and fixedly connected to the movable plate 8. The movable plate 8 is slidably connected inside the second slot 3. When the movable plate 8 moves inside the second slot 3, it can drive the iron plate 6 to move inside the first slot 2 via the connecting rod 7. The movable plate 8 is made of insulating material for easy insulation operation. The spring 9 is sleeved on the outside of the connecting rod 7 and located between the inner wall of the second slot 3 and the movable plate 8. Utilizing the elastic force of the spring 9, the movable plate 8, connecting rod 7, and iron plate 6 can be controlled to return to their original positions when the electromagnet 4 is de-energized. Simultaneously, when the electromagnet 4 is energized, the magnetic force applied to the iron plate 6 is greater than the elastic force of the spring 9. The conductive rod 10 is embedded inside the movable plate 8. The first terminal 11, the second terminal 12, the third terminal 13, and the fourth terminal 15 are all used in conjunction with the conductive rod 10. The conductive rod 10 facilitates better connection of the first terminal 11 and the second terminal 12, and also facilitates better connection of the third terminal 13 and the fourth terminal 15. The notch 17 is located on the side of the control box 1 away from the first empty slot 2, allowing the operator to manually push the movable plate 8 to move inside the second empty slot 3.

[0027] In one aspect of this embodiment, the alarm assembly includes a third terminal 13, a battery 14, a fourth terminal 15, and an alarm 16. The third terminal 13 is mounted on the bottom of the control housing 1, away from the electromagnet 4, and the battery 14 is electrically connected to the third terminal 13. The fourth terminal 15 is mounted on the top of the control housing 1, away from the electromagnet 4, and the alarm 16 is electrically connected to the fourth terminal 15. Power is supplied by the battery 14, thereby energizing and activating the alarm 16 when the third terminal 13 and the fourth terminal 15 are connected.

[0028] Working principle: In use, first connect the external electrical equipment to the first terminal 11 via a wire, and then move the movable plate 8 by pushing it through the notch 17, so that the conductive rod 10 inside the movable plate 8 connects the first terminal 11 and the second terminal 12. Figure 2 As shown, an external power supply is connected at the same time to form a closed circuit with electromagnet 4. At this time, electromagnet 4 is energized and has magnetism. The magnetic force of electromagnet 4 is used to attract iron plate 6. At the same time, the moving plate 8 can be released to control the normal operation of the equipment.

[0029] When the equipment is overloaded, the overload protection circuit breaker 5 detects the overload and cuts off the power to the control circuit. The electromagnet 4 loses its magnetism, causing the moving plate 8 to return to its original position under the elastic force of the spring 9. This, in turn, causes the connecting rod 7 and the iron plate 6 to return to their original positions. Figure 3 As shown, the conductive rod 10 connects the third terminal 13 and the fourth terminal 15. The battery 14, conductive rod 10, third terminal 13, fourth terminal 15, and alarm 16 form a closed circuit, thereby energizing the alarm 16 and enabling it to work, thus promptly alerting staff and facilitating practical application and operation.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
