Description

Technical Field

[0001] This invention relates to the technical field of power supply equipment, and more particularly to a power supply device for FTU commissioning and maintenance. Background Technology

[0002] In the technical and engineering fields, FTU often refers to a feeder terminal unit, which is a type of equipment in a power system used to monitor and control feeder lines in a distribution network. The power supply device for FTU commissioning and maintenance refers to the mechanical equipment used to connect the equipment to power during the maintenance of the feeder terminal unit.

[0003] During grid connection commissioning and power outage maintenance, each FTU obviously does not meet the conditions for power supply from the PT, which requires an external power supply to make the FTU work. The current solution is to use two power cables with exposed copper cores at both ends, one end connected to a 220V power socket or circuit breaker, and the other end connected to the FTU voltage acquisition terminal or power module to achieve the purpose of power supply to the FTU. This method of power supply is relatively dangerous and can easily lead to accidental contact by maintenance personnel. In addition, when storing the power cables, it is easy for the power cables to get tangled. This needs to be improved. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0005] In view of the problems of existing FTU commissioning and maintenance power supply devices that are prone to accidental contact by maintenance personnel and easy tangling of power cords, this invention is proposed.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a base component, including a support component, a transport component disposed on the support component, and a power-taking component disposed on the support component; a take-up and take-down component, including a rotating component disposed on the support component, a locking component disposed on the rotating component, and an unlocking component disposed on the support component; and a cable routing component, including a transmission component disposed on the rotating component, a reciprocating component disposed on the transmission component, and a cable routing component disposed on the reciprocating component.

[0010] As a preferred embodiment of the power supply device for FTU commissioning and maintenance described in this invention, the rotating assembly includes a main gear disposed on the rotating rod, a driven gear disposed on the support plate, and an internal gear ring disposed on the support plate; the driven gear is meshed and connected above the main gear, the upper inner wall of the internal gear ring is meshed and connected to the upper side of the driven gear, the front end of the internal gear ring is fixedly connected to the rear storage tray, and the rear side is rotatably connected to the front end of the support plate.

[0011] As a preferred embodiment of the power supply device for FTU commissioning and maintenance described in this invention, the locking assembly includes a storage box disposed at the rear end of the support plate, a sliding groove disposed on the inner wall of the storage box, a slider disposed inside the sliding groove, an arc-shaped block disposed on the slider, a ratchet disposed on the storage box, a groove disposed on the rotating rod, a pawl disposed on the inner wall of the groove, and a spring disposed on the pawl.

[0012] As a preferred embodiment of the power supply device for FTU commissioning and maintenance described in this invention, the unlocking component includes a long rod disposed on the arc-shaped block, a threaded disc disposed inside the storage box, an arc-shaped groove disposed on the threaded disc, a connecting plate disposed on the storage box, a cavity disposed on the connecting plate, and a coil spring disposed inside the cavity.

[0013] As a preferred embodiment of the power supply device for FTU commissioning and maintenance described in this invention, the transmission assembly includes a rotating rod disposed on the base plate, a sprocket disposed on the rotating rod and the rotating rod, and a chain disposed on the sprocket.

[0014] As a preferred embodiment of the power supply device for FTU commissioning and maintenance described in this invention, the reciprocating assembly includes a reciprocating groove disposed on the outer wall of the rotating rod, a moving block disposed inside the reciprocating groove, and a moving ring disposed on the outer wall of the rotating rod.

[0016] The beneficial effects of this invention are as follows: By pulling the explosion-proof plug, the rear storage tray rotates. This rotation drives the internal gear ring, which in turn drives the main gear, causing the front storage tray to rotate in the opposite direction, thus completing the secondary cable arrangement. Simultaneously, the ratchet and pawl work together to lock the device and prevent cable retraction. When retraction is needed, simply rotate the threaded disc, causing the arc-shaped groove to expand and disengage from the ratchet via a long rod. This causes the coil spring to drive the rotating rod, allowing the rotating disc to collect the secondary cable. The rotation of the storage tray, via a chain, causes the rotating rod to rotate, resulting in the reciprocating movement of the cable reel, completing the secondary cable arrangement and achieving automatic cable routing.

[0025] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0028] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0029] Example 1, referring to Figures 1 to 7 The first embodiment of the present invention provides a power supply device for FTU commissioning and maintenance. The device includes a base component 100, a support component 101, a transport component 102 disposed on the support component 101, and a power supply component 103 disposed on the support component 101.

[0030] The support component 101 is used to support the entire device, the transport component 102 is set up to facilitate maintenance personnel to move the equipment, and the power supply component 103 is set up to connect the 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 support component 101, a locking component 202 disposed on the rotating component 201, and an unlocking component 203 disposed on the support component 101.

[0032] The rotating component 201 is configured to control the two storage trays 103b to rotate together, so that the cables at both ends of the device can extend synchronously. The locking component 202 is configured to control the rotating rod 103a to rotate only in one direction and not retract. The unlocking component 203 is configured to unlock the locking component 202 and control the cable retraction.

[0033] Preferably, the operation of the rotating component 201 causes the two storage trays 103b to rotate together, causing the secondary cable 103c to extend to both sides. When storage is required, it is only necessary to control the operation of the unlocking component 203 to unlock the locking component 202. The reset spring 202h will drive the rotating rod 103a to rotate, thereby restoring the cable to its original position.

[0034] Furthermore, the wiring 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 wiring component 303 disposed on the reciprocating component 302.

[0035] The transmission component 301 is used to control the rotating rod 301a to rotate together with the rotating rod 103a, and the reciprocating component 302 is used to control the cable laying component 303 to achieve back-and-forth reciprocating motion, so that the cable laying component 303 can arrange the secondary cable 103c in an orderly manner on the storage tray 103b.

[0036] Preferably, the operation of the rotating component 201 causes the transmission component 301 to drive the reciprocating component 302 to operate, thereby causing the cable arrangement component 303 to operate together with the reciprocating component 302 to arrange the cable on the storage tray 103b and complete the storage.

[0037] In summary: By controlling the operation of the power-taking component 103, the rotating component 201 is made to rotate, thereby extending the cable to both sides and connecting the two ends of the cable to the power source and FTU respectively, thus completing the power taking. When the cable extends, the locking component 202 restricts the rotating component 201, so that the rotating component 201 cannot return to its original position. When it is necessary to store the cable, simply control the operation of the unlocking component 203 to automatically retract the cable. At the same time, when the rotating component 201 rotates, it drives the reciprocating component 302 to operate, so that the cable tray 303 evenly stores the cable on the storage tray 103b.

[0038] Example 2, refer to Figures 1-5 The second embodiment of the present invention includes: a support component 101 including a base plate 101a, a support plate 101b disposed on the base plate 101a, and a support frame 101c disposed at the bottom end of the base plate 101a.

[0039] The base plate 101a is used to connect the support frame 101c and the support plate 101b. The support plate 101b is used to place the take-up and take-down components 200, so that the equipment can operate normally. The support frame 101c is used to support the entire device and prevent the Qingdao situation from occurring during the operation of the equipment.

[0040] Furthermore, the transport component 102 includes a connecting frame 102a disposed on the support plate 101b, a telescopic rod 102b disposed inside the connecting frame 102a, and a transport wheel 102c disposed at the rear end of the base plate 101a.

[0041] The connecting frame 102a is used to house the telescopic rod 102b, allowing the telescopic rod 102b to rise and fall inside the connecting frame 102a, thus facilitating the handling of equipment by operators. The transport wheel 102c is used to cooperate with the telescopic rod 102b for convenient transportation.

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

[0043] The rotating rod 103a is used to connect the storage tray 103b and the support plate 101b, so that the storage tray 103b rotates together with the rotating rod 103a to complete the cable winding and unwinding. The secondary cable 103c can be quickly connected to the power supply through the explosion-proof plug 103d. 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 disposed on the rotating rod 103a, a driven gear 201b disposed on the support plate 101b, and an internal gear ring 201c disposed on the support plate 101b; the driven gear 201b is meshed above the main gear 201a, the upper inner wall of the internal gear ring 201c is meshed with the upper side of the driven gear 201b, the front end of the internal gear ring 201c is fixedly connected to the rear storage tray 103b, 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 driven gear 201b, so that when the internal gear ring 201c rotates, it rotates in the opposite direction to the internal gear ring 201c, thereby causing the two storage trays 103b to rotate in opposite directions.

[0046] Preferably, when power is needed, by pulling both ends of the cable, the two storage trays 103b rotate in opposite directions, thereby extending the secondary cable 103c. Then, by setting the locking component 202, the pulled-out cable cannot be retracted, so that one end of the explosion-proof plug 103d of the secondary cable 103c is connected to the power source, and the other end is connected to the FTU through the aviation connector 103f to complete the power supply from the FTU.

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

[0048] The storage box 202a is used to place the locking component 202, the slide 202b is used to restrict the movement trajectory of the slider 202c, the arc block 202d is used to restrict the ratchet 202e so that it cannot rotate, thereby making the rotating rod 103a rotate only 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 arc plate so that it cannot rotate. This allows the ratchet 202e to work with the pawl 202g to make the rotating rod 103a rotate only in one direction, thus preventing the extended cable from being actively retracted and facilitating power supply to the device.

[0050] In summary: Pulling the explosion-proof plug 103d causes the secondary cable 103c to rotate, which in turn rotates the rear storage tray 103b. The rotation of the rear storage tray 103b rotates the internal gear ring 201c, which in turn rotates the main gear 201a. This causes the front storage tray 103b to rotate in the opposite direction, extending the secondary cable 103c. This allows one end of the secondary cable 103c to connect to the power source, and the other end to the FTU device, thus powering the device. Simultaneously, the ratchet 202e and pawl 202g work together to lock the secondary cable 103c in the device, preventing cable retraction and ensuring the device can draw power normally.

[0051] Example 3, referring to Figures 4-7 The third embodiment of the present invention includes: an unlocking component 203 comprising a long rod 203a disposed on an arc-shaped block 202d, a threaded disc 203b disposed inside the storage box 202a, an arc-shaped groove 203c disposed on the threaded disc 203b, a connecting plate 203d disposed on the storage box 202a, a cavity 203e disposed on the connecting plate 203d, and a coil spring 203f disposed inside the cavity 203e.

[0052] The rotation of the threaded disc 203b drives the arc groove 203c to rotate. The arc groove 203c is designed to work with the long rod 203a to drive the arc block 202d to expand and contract synchronously. The cavity 203e is designed to house the coil spring 203f. The coil spring 203f is designed to control the rotating rod 103a to rotate back, thereby enabling the secondary cable 103c to be automatically retracted.

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

[0054] Furthermore, the transmission assembly 301 includes a rotating rod 301a disposed on the base 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.

[0055] The rotating rod 301a is used to control the operation of the reciprocating assembly 302, and the sprocket 301b and chain 301c enable the rotating rod 301a to rotate together with the rotating rod 103a.

[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 movement trajectory of the moving block 302b, and the moving ring 302c is used to drive the ribbon cable board to follow the moving block 302b to achieve back-and-forth reciprocating motion.

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

[0059] Furthermore, the cable assembly 300 includes a through hole 303a disposed on the base plate 101a, an L-shaped rod 303b disposed inside the through hole 303a, and a coiled wire ring 303c disposed on the L-shaped rod 303b.

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

[0061] Preferably, the moving block 302b drives the moving ring 302c to move, so that the moving ring 302c drives the coil ring 303c to reciprocate back and forth through the L-shaped rod 303b, thereby facilitating the storage of the secondary cable 103c.

[0062] In summary: Pulling the explosion-proof plug 103d causes the rear storage tray 103b to rotate. This rotation of the rear storage tray 103b drives the internal gear ring 201c to rotate, causing the driven gear 201b to drive the main gear 201a to rotate. This, in turn, causes the front storage tray 103b to rotate in the opposite direction, completing the discharge of the secondary cable 103c. Simultaneously, the ratchet 202e and pawl 202g work together to lock the device, preventing cable retraction. When retraction is needed... Simply rotate the threaded disc 203b, causing the arc-shaped groove 203c to expand and disengage from the ratchet 202e via the long rod 203a, which in turn causes the coil spring 203f to drive the rotating rod 103a to rotate, thereby allowing the rotating disc to collect the secondary cable 103c. When the collecting disc 103b rotates, the chain 301c causes the rotating rod 301a to rotate, which in turn causes the cable ring 303c to move back and forth, completing the arrangement of the secondary cable 103c and achieving the effect of automatic cable arrangement.
