[0023] In order to better understand the purpose, structure and function of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Example

[0024] See also Figures 1 to 5 The present embodiment discloses an elevator energy-saving device, comprising a cabinet 1 and a cabinet door 2, characterized in that: a converter 3 is arranged in the cabinet 1, which can convert AC power into DC power, or convert DC power into AC power, and the converter 3 is equipped with a wiring panel 301, which is located on the outer facade of the cabinet 1, and the wiring panel 301 includes a wiring part 3011 and a plug board 3012. An industrial power supply 4 is arranged in the cabinet 1, and the industrial power supply 4 is a high-power bidirectional DCDC power supply. The industrial power supply 4 is electrically connected to the converter 3, and a control panel 101 is arranged on the upper side of the cabinet 1. The control panel 101 includes a control switch 1011 and an emergency switch 1012. The control switch 1011 is electrically connected to the industrial power supply 4. The emergency switch 1012 is electrically connected to the control switch 1011 and the converter 3. It can be used to control the start and stop of the power supply in an emergency. A power monitoring module 201 is provided on the inner side of the cabinet door 2. The power monitoring module 201 is electrically connected to the industrial power supply 4 to monitor the power status of the industrial power supply 4 in real time. The power monitoring module 201 is communicatively connected to a display screen 202. The display screen 202 is located on the outer surface of the cabinet door 2 and can display the power status more intuitively. Figure 4 For the sake of display effect, the power cord connection is not shown.

[0025] The industrial power sources 4 are provided with at least two, which are electrically connected in parallel. The multiple industrial power sources 4 make the subsequent energy storage use more flexible.

[0026] The industrial power supply 4 is provided with positive and negative pole posts, which are electrically connected via a connector 401. A pressure cap 402 is provided on the top of the positive and negative pole posts. The pressure cap 402 is made of insulating material and plays a protective role to prevent accidental electric shock. The pressure cap 402 is threadedly connected to the positive and negative pole posts, making the parallel wiring between the industrial power supplies 4 more reliable and less likely to cause accidents due to poor contact.

[0027] There is a digital number under the control switch 1011. The industrial power supply 4 is assigned a digital number, which corresponds to the digital number under the control switch 1011. The operator can accurately control the industrial power supply 4 that needs to be turned on or off.

[0028] The cabinet door 2 is provided with a door lock 203, and the door lock 203 is equipped with a handle 2031 and a lock hook 2032. The cabinet body 1 is provided with a lock ring 104 adapted to the lock hook 2032. When the cabinet door 2 is closed, the lock hook 2032 falls into the lock ring 104 to lock the cabinet door 2. The handle 2031 makes it convenient for the operator to open and close the cabinet door 2 and lock the cabinet door 2.

[0029] The top of the cabinet 1 is provided with a hoisting portion 102. Since the entire device is relatively heavy, mechanical assistance is required when it is moved or transported. The hoisting portion 102 facilitates mechanical hoisting and transportation.

[0030] The cabinet 1 is provided with ventilation grilles 103 on both sides. When the device is running, the industrial power supply 4 in the cabinet 1 is cooled through the ventilation grilles 103 to ensure stable operation of the industrial power supply 4.

[0031] The shell of the emergency switch 1012 is made of transparent acrylic material, and is equipped with a red and green light group inside.

The operator can quickly determine the state of the emergency switch 1012 by the color of the light.

[0032] The power monitoring module 201 is a voltage monitoring module. Voltage monitoring estimates the remaining battery power by measuring the battery voltage. Using this method, the power monitoring module 201 can be directly connected to the industrial power supply 4, and the power monitoring module 201 will calculate the remaining battery power.

[0033] Working principle: When the elevator traction motor generates regenerative electric energy, it is input into the converter 3 through the wires and the connection part 3011. The converter 3 converts the alternating current into direct current and stores it in a plurality of parallel industrial power supplies 4. The display screen 202 can be used to intuitively understand the amount of electricity contained in each industrial power supply 4. When this part of the stored electric energy is needed, the control switch 1011 can be used selectively to partially or fully use the parallel industrial power supplies 4. The electric energy output by the industrial power supply 4 enters the converter 3, converts the direct current into alternating current, and transmits the electric energy through the power strip 3012.

[0034] It should be understood that all the above preferred embodiments are illustrative rather than restrictive, and various modifications or variations made by those skilled in the art to the specific embodiments described above under the concept of the present invention should be within the legal protection scope of the present invention.
