The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0028] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0029] Example 1, reference Figure 1 to Figure 7 , which is the first embodiment of the present invention, provides a power supply device for FTU debugging and maintenance, which includes a basic component 100, including a support component 101, a transportation component 102 arranged on the support component 101, and a power supply component 103 arranged on the support component 101.

[0030] Among them, the support component 101 is used to support the entire device, the transportation component 102 is used to facilitate maintenance personnel to carry equipment, and the power supply component 103 is used to connect a 220V power supply and FTU, thereby facilitating on-site personnel to carry out maintenance work.

[0031] Furthermore, the retractable component 200 includes a rotating component 201 disposed on the supporting component 101 , a locking component 202 disposed on the rotating component 201 , and an unlocking component 203 disposed on the supporting component 101 .

[0032] Among them, the rotating component 201 is used to control the two storage trays 103b to rotate together, so that the cables at both ends of the device can be extended synchronously. The locking component 202 is used to control the rotating rod 103a so that it can only rotate in one direction and cannot be recovered. The unlocking component 203 is used to unlock the locking component 202 and control the cable recovery at the same time.

[0033] Preferably, the two storage trays 103b are rotated together by the operation of the rotating component 201, so that the secondary cables 103c extend to both sides. When storage is needed, it is only necessary to control the operation of the unlocking component 203 to unlock the locking component 202, and the return spring 202h will drive the rotating rod 103a to rotate, thereby restoring the cable to its original position.

[0034] Furthermore, the cable arrangement component 300 includes a transmission component 301 disposed on the rotating component 201 , a reciprocating component 302 disposed on the transmission component 301 , and a cable arrangement component 303 disposed on the reciprocating component 302 .

[0035] The transmission assembly 301 is used to control the rotating rod 301a to rotate along with the rotating rod 103a, and the reciprocating assembly 302 is used to control the cable assembly 303 to reciprocate back and forth, so that the cable assembly 303 arranges the secondary cables 103c in an orderly manner on the storage tray 103b.

[0036] Preferably, the transmission assembly 301 drives the reciprocating assembly 302 to operate through the operation of the rotating assembly 201, so that the cable arrangement assembly 303 operates together with the reciprocating assembly 302, and the cables are arranged on the storage tray 103b to complete the storage.

[0037] In summary: by controlling the operation of the power supply component 103, the rotating component 201 is rotated, so that the cable extends to both sides, so that the two ends of the cable are connected to the power supply and FTU respectively, so as to complete the power supply. When the cable is extended, the locking component 202 will limit the rotating component 201, so that the rotating component 201 cannot return to its original position. When storage is needed, it is only necessary to control the operation of the unlocking component 203 to automatically retract the cable. At the same time, when the rotating component 201 rotates, it will drive the reciprocating component 302 to operate, so that the cable arrangement component 303 can evenly store the cables on the storage tray 103b.

[0038] Example 2, reference Figure 1 to Figure 5 , which is a second embodiment of the present invention, comprises: a supporting assembly 101 comprises a bottom plate 101a, a supporting plate 101b arranged on the bottom plate 101a, and a supporting frame 101c arranged at the bottom end of the bottom plate 101a.

The transport wheels 102c are used to cooperate with the telescopic rod 102b for convenient transportation.

[0042] Furthermore, the power taking component 103 includes a rotating rod 103a arranged on the support plate 101b, a storage tray 103b arranged on the rotating rod 103a, a secondary cable 103c arranged on the storage tray 103b, an explosion-proof plug 103d and an aviation plug adapter 103e arranged on the secondary cable 103c, and an aviation connector 103f arranged on the aviation plug adapter 103e.

[0043] Among them, the setting of the rotating rod 103a is used to connect the storage tray 103b and the support plate 101b, so that the storage tray 103b can rotate together with the rotating rod 103a, thereby completing the retraction and release of the cables. The secondary cable 103c can be quickly connected to the power supply through the explosion-proof plug 103d, and the setting of the aviation connector 103f is used to facilitate the connection between the cable and the FTU.

[0044] Furthermore, the rotating assembly 201 includes a main gear 201a arranged on the rotating rod 103a, a slave gear 201b arranged on the support plate 101b, and an inner gear ring 201c arranged on the support plate 101b; the slave gear 201b is meshingly connected above the main gear 201a, the upper inner wall of the inner gear ring 201c is meshingly connected to the upper side of the slave gear 201b, the front end of the inner gear ring 201c is fixedly connected to the storage tray 103b on the rear side, and the rear side is rotatably connected to the front end of the support plate 101b.

[0045] The main gear 201a is configured to cooperate with the slave gear 201b, so that the inner gear ring 201c rotates in the opposite direction to the inner gear ring 201c, thereby making the two storage trays 103b rotate in opposite directions.

[0046] Preferably, when power is needed, the two ends of the cable are pulled so that the two storage trays 103b rotate in opposite directions, thereby extending the secondary cable 103c, and then the locking assembly 202 is set so that the pulled out cable cannot be recovered, so that one end of the explosion-proof plug 103d of the secondary cable 103c is connected to the power supply, and the other end is connected to the FTU through the aviation connector 103f, thereby completing the FTU power supply.

[0047] Furthermore, the locking assembly 202 includes a storage box 202a arranged at the rear end of the support plate 101b, a slide groove 202b arranged on the inner wall of the storage box 202a, a slider 202c arranged inside the slide groove 202b, an arc block 202d arranged on the slider 202c, a ratchet 202e arranged on the storage box 202a, a groove 202f arranged on the rotating rod 103a, a pawl 202g arranged on the inner wall of the groove 202f, and a spring 202h arranged on the pawl 202g.

[0048] Among them, the storage box 202a is used to place the locking assembly 202, the slide groove 202b is used to limit the moving trajectory of the slider 202c, the arc block 202d is used to limit the ratchet 202e so that it cannot rotate, so that the rotating rod 103a can only rotate in one direction, the groove 202f is used to place the pawl 202g, and the spring 202h is used to push the pawl 202g to expand outward.

[0049] Preferably, the ratchet 202e is fixed by the provision of an arc plate so that it cannot rotate, so that the ratchet 202e cooperates with the pawl 202g to allow the rotating rod 103a to rotate only in one direction, so that the extended cable cannot be actively recovered, making it convenient for the device to draw power.

[0050] In summary: by pulling the explosion-proof plug 103d, the secondary cable 103c drives the storage tray 103b on the rear side to rotate. When the storage tray 103b on the rear side rotates, the inner gear ring 201c will be driven to rotate, and the main gear 201a will be driven to rotate, thereby driving the storage tray 103b on the front side to rotate in the opposite direction, completing the extension of the secondary cable 103c, so that one end of the secondary cable 103c is connected to the power supply, and the other end is connected to the FTU equipment, completing the power connection of the equipment, and at the same time, the ratchet 202e and the pawl 202g cooperate with each other to lock the secondary cable 103c in the equipment to prevent the cable from being recovered, so that the equipment can be powered normally.

[0051] Example 3, reference Figures 4 to 7 , which is the third embodiment of the present invention, comprising: the unlocking component 203 comprises a long rod 203a arranged on the arc block 202d, a threaded disk 203b arranged inside the storage box 202a, an arc groove 203c arranged on the threaded disk 203b, a connecting plate 203d arranged on the storage box 202a, a cavity 203e arranged on the connecting plate 203d, and a coil spring 203f arranged inside the cavity 203e.

[0052] Among them, the rotation of the threaded disk 203b is used to drive the rotation of the arc groove 203c, and the setting of the arc groove 203c is used to cooperate with the long rod 203a to drive the arc block 202d to expand and contract synchronously. The setting of the cavity 203e is used to place the coil spring 203f, and the setting of the coil spring 203f is used to control the rotating rod 103a to rotate back, so that the secondary cable 103c is automatically recovered.

[0053] Preferably, by rotating the threaded disk 203b, the arc groove 203c squeezes the long rod 203a, so that the multiple arc blocks 202d expand outward synchronously. After the arc plate expands, the restriction of the ratchet 202e is cancelled, and the coil spring 203f drives the rotating wheel and the ratchet 202e to rotate together, driving the secondary cable 103c to be recovered into the storage disk 103b.

[0054] Furthermore, the transmission assembly 301 includes a rotating rod 301a disposed on the bottom plate 101a, a sprocket 301b disposed on the rotating rod 301a and the rotating rod 103a, and a chain 301c disposed on the sprocket 301b.

[0056] Furthermore, the reciprocating assembly 302 includes a reciprocating groove 302a disposed on the outer wall of the rotating rod 301a, a moving block 302b disposed inside the reciprocating groove 302a, and a moving ring 302c disposed on the outer wall of the rotating rod 301a.

[0057] The reciprocating groove 302a is used to limit the moving track of the moving block 302b, and the moving ring 302c is used to drive the cable tray to follow the moving block 302b to achieve back and forth reciprocating motion.

[0058] Preferably, the coil spring 203f drives the rotating rod 103a to rotate, so that the two storage trays 103b rotate together, and the sprocket 301b and the chain 301c are set to make the rotating rod 301a rotate along with it, so that the moving block 302b drives the moving ring 302c to achieve reciprocating motion back and forth.

[0059] Furthermore, the cable arrangement component 300 includes a through hole 303 a disposed on the bottom plate 101 a , an L-shaped rod 303 b disposed inside the through hole 303 a , and a cable coiling ring 303 c disposed on the L-shaped rod 303 b .

[0060] The through hole 303a is provided to facilitate the movement of the L-shaped rod 303b, and the cable arrangement ring is provided to drive the secondary cables 103c to be arranged in an orderly manner inside the storage tray 103b.

[0061] Preferably, the moving ring 302c is driven to move by the moving block 302b, so that the moving ring 302c drives the cable coiling ring 303c to realize forward and backward reciprocating motion through the L-shaped rod 303b, thereby facilitating the storage of the secondary cable 103c.

[0062] In summary: by pulling the explosion-proof plug 103d, the storage tray 103b at the rear side rotates, and when the storage tray 103b at the rear side rotates, the inner gear ring 201c is driven to rotate, so that the slave gear 201b drives the main gear 201a to rotate, thereby driving the storage tray 103b at the front side to rotate in the opposite direction, completing the discharge of the secondary cable 103c. At the same time, the ratchet 202e and the pawl 202g can lock the device under the mutual cooperation to prevent the cable from being recycled. When recycling is needed It is only necessary to rotate the threaded disk 203b so that the arc groove 203c controls the arc plate to expand and disengage from the ratchet 202e through the long rod 203a, so that the coil spring 203f drives the rotating rod 103a to rotate, so that the rotating disk can store the secondary cable 103c; when the storage disk 103b rotates, the chain 301c can be used to rotate the rotating rod 301a so that the cable ring 303c can move back and forth, thereby completing the arrangement of the secondary cables 103c and achieving the effect of automatic cable arrangement.
