DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] like Figure 1As shown, the utility model provides an output mechanism of a switchable three-phase emergency cable reel, comprising: a first three-phase socket 1 and a second three-phase socket 2, the first three-phase socket 1 and the second three-phase socket 2 are both provided with output interfaces, and the output interfaces are respectively a first interface 3, a second interface 4 and a third interface 5; wherein the output interface of the first three-phase socket 1 is respectively connected to the output interface of the second three-phase socket 2, so that the three-phase phase sequence of the first three-phase socket 1 and the second three-phase socket 2 is opposite.

[0024] The first interface 3 on the first three-phase socket 1 is connected to the second interface 4 on the second three-phase socket 2, and the second interface 4 on the first three-phase socket 1 is connected to the first interface 3 on the second three-phase socket 2, so that the three-phase sequence of the first three-phase socket 1 and the second three-phase socket 2 is opposite.

[0025] In this embodiment, the first interface 3 is the L1 phase on the first three-phase socket 1 and the second three-phase socket 2, the second interface 4 is the L2 phase on the first three-phase socket 1 and the second three-phase socket 2, and the third interface 5 is the L3 phase on the first three-phase socket 1 and the second three-phase socket 2, wherein the L1 phase on the first three-phase socket 1 is connected to the L2 phase on the second three-phase socket 2, and the L2 phase on the second three-phase socket 2 is connected to the L1 phase on the first three-phase socket 1, thereby achieving the purpose of making the three-phase sequence of the first three-phase socket 1 and the second three-phase socket 2 opposite.

[0026] When an electrical device draws power, the power plug of the device is randomly connected to the first three-phase socket 1 or the second three-phase socket 2. If the device can be used normally, the power is drawn successfully; if the device is reversed or the phase sequence is incorrect, the power plug needs to be unplugged and reinserted into another three-phase socket to complete the quick turnaround and meet the power needs of the device.

[0027] The third interface 5 of the first three-phase socket 1 is connected to the third interface 5 of the second three-phase socket 2 .

[0028] The first three-phase socket 1 and the second three-phase socket 2 are output interfaces and also include a fourth interface 6 and a fifth interface 7. The fourth interface 6 on the first three-phase socket 1 is connected to the fourth interface 6 on the second three-phase socket 2, and the fifth interface 7 on the first three-phase socket 1 is connected to the fifth interface 7 on the second three-phase socket 2 to ensure the safety of electricity use of the equipment.

[0029] In this embodiment, the fourth interface 6 and the fifth interface 7 on the first three-phase socket 1 and the second three-phase socket 2 are divided into an N phase and a PE phase.

[0030] like Figure 2As shown, an output mechanism of a reversible three-phase emergency cable reel also includes a reversing adapter, which is an independent structure. When the second electrical equipment draws power, the reversing adapter is plugged into the first three-phase socket 1 or the second three-phase socket 2 according to actual usage to meet the needs of rapid reversal of the second electrical equipment.

[0031] The reversing adapter includes a male connector 8 and a female connector 9. When the reversing adapter is plugged into the first three-phase socket 1 or the second three-phase socket 2, the male connector 8 is connected to the first three-phase socket 1 or the second three-phase socket 2, and the female connector 9 is connected to the electrical device.

[0032] The male head 8 is provided with an input interface, and the female head 9 is provided with an output interface, and the output interface and the input interface correspond to the sixth interface 10, the seventh interface 11 and the eighth interface 12; the output interface in the reversing adapter is connected to the input interface to realize reversal, the input interface is connected to the three-phase socket, and the output interface is connected to the electrical equipment.

[0033] Specifically, the input interface on the male connector 8 is connected to the output interface on the female connector 9, so that the three-phase sequence of the male connector 8 and the female connector 9 is opposite, that is, the seventh interface 11 of the male connector 8 is connected to the eighth interface 12 of the female connector 9, and the eighth interface 12 of the male connector 8 is connected to the seventh interface 11 of the female connector 9, so that the three-phase sequence of the male connector 8 and the female connector 9 is opposite.

[0034] In this embodiment, the sixth interface 10 on the male connector 8 and the female connector 9 is the L1 phase, the seventh interface 11 is the L2 phase, and the eighth interface 12 is the L3 phase. The L2 phase of the male connector 8 of the reversing adapter is connected to the L3 phase of the female connector 9, and the L3 phase of the male connector 8 is connected to the L2 phase of the female connector 9, so that the three-phase sequence of the male connector 8 and the female connector 9 is reversed.

[0035] A ninth interface 13 and a tenth interface 14 are also provided on the male connector 8 and the female connector 9. The ninth interface 13 on the male connector 8 is connected to the ninth interface 13 on the female connector 9, and the tenth interface 14 on the male connector 8 is connected to the tenth interface 14 on the female connector 9 to ensure the safety of electrical use of the equipment.

[0036] In this embodiment, the ninth interface 13 on the male connector 8 and the female connector 9 is an N phase, and the tenth interface 14 is a PE phase.

[0037] In this embodiment, when an electrical device draws power, the power plug of the electrical device is randomly connected to one of the first three-phase socket 1 or the second three-phase socket 2. If the device can be used normally, power is drawn successfully; if the device is reversed or the phase sequence is incorrect, the power plug needs to be unplugged and reinserted into another three-phase socket to meet the power demand of the device; when a second electrical device draws power, the power of the second electrical device is plugged into the remaining three-phase socket. If the device can be used normally, power is drawn successfully; if the device is reversed or the phase sequence is incorrect, the power plug needs to be unplugged, and then replaced with a reversing adapter, and reconnected to meet the power demand of the device.

[0038] In this device, by changing the phase sequence of one of the three-phase output sockets, one of the two three-phase outputs is positive and the other is negative. When one electrical device is reversed or the phase sequence is incorrect, the power plug of the device can be quickly reversing by simply inserting it into another socket. In addition, an additional reversing conversion connector is added. When the second electrical device is reversed or the phase sequence is incorrect, the need for rapid reversing of the second electrical device can be met by connecting the reversing conversion connector. The reversing operation is simple and fast, and there is no need to disassemble the plug and socket for rewiring, which saves time and effort and is safe and reliable.

[0039] The reversible three-phase emergency cable reel has a simple manufacturing process and can be remade or modified on an existing three-phase cable reel (including two three-phase outputs). The first step of the transformation can be completed by simply changing the phase sequence of one of the three-phase output sockets so that one of the two three-phase outputs is positive and the other is reverse. Secondly, a three-phase reversing adapter is made, with one male and one female having opposite phase sequences. The integrated design is both convenient to carry and easy to operate.

[0040] On the other hand, the present embodiment also provides a reversible three-phase emergency cable reel, including: a cable reel body and a three-phase cable arranged on the cable reel body, a power switch and a protector, a three-phase input plug, two three-phase output sockets (i.e., a first three-phase socket 1 and a second three-phase socket 2) and two single-phase output sockets. The two three-phase output sockets have opposite phase sequences, which are different from the two three-phase outputs with the same phase sequence currently used. A reversing adapter is also included, which matches the cable reel output socket, and the three-phase input and output phase sequences are opposite.

[0041] It should be noted that the switchable three-phase emergency cable reel provided in this embodiment has all the advantages of the output mechanism of the switchable three-phase emergency cable reel provided in the above embodiments.

Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
