Embodiment Construction

[0034] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0035]The present invention is a mobile non-contact power supply device, which is composed of a primary 10 and a secondary 20 . The primary 10 is fixed on the ground and laid along the line; the secondary 20 is placed on moving equipment such as a car, and runs accordingly.

[0036] The primary 10 is composed of a primary winding 11 , a primary winding fixing bracket 12 and the like.

[0037] The secondary 20 is composed of a non-closed secondary iron core 22 , a secondary winding 21 , an electromagnet engaging device 200 and the like.

[0038] The primary winding fixing bracket 12 supports the primary winding 11 to reduce sagging caused by its own weight. The primary winding 11 passes through the secondary winding 21 and the non-closed secondary core 22 without contact, so that the primary and secondary forms an electromagnetic coupling stru...

Abstract

The invention discloses a mobile noncontact uninterrupted power supply device. A primary winding (11) of the device is laid along a line, and a primary winding fixing bracket (12) is arranged in a certain distance. The power supply device is also provided with a proximity position sensor and a leaving position sensor for sending switch-on or switch-off signals to a secondary switch. The proximity position sensor consists of a proximity signal generator (131) and a proximity signal receiver (281); and the leaving position sensor consists of a leaving signal generator (132) and a leaving signal receiver (282). The proximity signal generator (131) and the leaving signal generator (132) are arranged at two ends of the primary winding fixing bracket (12); and the proximity signal receiver (281) and the leaving signal receiver (282) are arranged at two ends of a secondary winding (20). Electromagnet attraction devices (200) are positioned on two pole plates of a secondary iron core (22). The primary winding (11) passes through a secondary winding (21) and an iron core (22) in a noncontact mode to form an electromagnetic coupling structure; and alternating current is supplied in the primary winding (11).

Description

technical field [0001] The invention relates to a power supply device in the field of automatic transportation, in particular to a contactless and uninterrupted power supply method and device for transportation equipment. Background technique [0002] The field of automatic conveying needs to adopt contactless power supply. [0003] The so-called contactless power supply refers to the realization of power transmission when there is no electrical connection and physical contact between the transmission line and the load side, and even when there is relative movement between the two. The theoretical basis of the contactless power supply system is the principle of electromagnetic induction. The new contactless power supply system uses electromagnetic induction coupling technology combined with modern power electronics technology, and does not require mechanical contact between the power supply and the electrical equipment for power transmission. Compared with the traditional ...
