Description

Technical Field

[0001] The present invention relates to the technical field of power distribution devices, and in particular to a modular power distribution device. Background Art

[0002] The design principle of modular distribution device is to decompose the whole distribution system into multiple independent functional modules, which can be tested and repaired independently, greatly improving the reliability and maintainability of the system. By combining pre-designed standardized modules, it can meet the needs of different power systems.

[0003] However, when different modules are pulled out, the wires connected to the rear end of the modules also need to be pulled out synchronously. Due to the complexity of the wires, when these wires are repeatedly pulled out, it is easy for the wires to overlap or become tangled. This will cause the extendable length of the wires to be reduced during the subsequent module extraction process, making it impossible to pull out the module, or the wires may be stretched straight when pulled out, causing the module to lose power. At the same time, when an accident such as a fire occurs in the wiring box, the device needs to be safely and quickly powered off. If a circuit breaker is used directly, it is easy to get burned. Therefore, it is necessary to quickly and conveniently power off the module safely. Summary of the invention

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. Push the distribution module toward the distribution shell, so that the rack 1 drives the gear 2 to rotate, thereby driving the turning rod to slide toward the distribution module. While the distribution module slides, it drives the guide wheel to fold the wires pulled out of the distribution module into a horizontal U shape, so that when the wires are pulled out and pulled back into the wire box, the wires will not be scattered. At the same time, the wire baffle slides with the turning rod, so that the wires are limited when they are folded, preventing multiple wires from overlapping, thereby shortening the distance that the wires can be pulled out after overlapping, making it impossible to pull out the distribution module;

[0016] 2. The L-shaped clamping block 1 is driven to clamp on the inner wall of the clamping groove by pushing the mounting shell. When the plug-in rod needs to be pulled out, the driving bevel block is driven to contact the driven bevel block by rotating the rotating ring, so that the driven bevel block and the L-shaped clamping block are slightly rotated at the beginning, so that the L-shaped clamping block 1 is separated from the inner wall of the clamping groove. Then the plug-in rod can be pulled out from the plug-in column to the inside, and at the same time, the wire blocking plate moves toward the direction of the power distribution module, so that the pressing plate contacts with one side surface of the mounting shell, so that a second thrust is applied to the L-shaped clamping block 1 to prevent the L-shaped clamping block 1 from not being clamped on the clamping groove. If the clamping is completed, the pressing plate slides on the inner side of the wire blocking plate, and the spring 2 is compressed, thereby storing elastic potential energy, continuously contacting the side surface of the mounting shell, and preventing the plug-in rod from accidentally falling off.

[0017] 3. Pay out the wire through the winding wheel, and push the guide wheel 2 to slide in the direction of the circuit breaker through the spring 8. When the guide wheel 2 slides, part of the folded wire will be released, so that the wire will not be too tight when the wire box is pulled out. At the same time, when the guide wheel 2 slides, it pushes the side surface of the wire baffle plate to make the wire baffle plate start to rotate. At the same time, the sliding rod is no longer stuck by the resistance block and slides away from the wire baffle plate. When the wire box is pulled out too far, the wire baffle plate 2 is pushed by the sliding rod to resist and push the sliding inclined block. The sliding inclined block pushes the empty slot to slide upward, so that the L-shaped clamping block 2 is no longer stuck by the arc edge rod, and the elastic potential energy of the spring 4 is released to push the connector out of the circuit breaker to the inside, so as to achieve quick and safe power off.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] See also Figure 1-Figure 13The present invention provides a technical solution: a modular power distribution device, comprising a power distribution shell 1, a power distribution module 2 is slidably connected to the top of the inner cavity of the power distribution shell 1, a wire box 3 is slidably connected to the bottom of the inner cavity of the power distribution shell 1, a plurality of connection structures are installed on the side of the power distribution module 2 close to the power distribution shell 1, and a wire 13 is fixedly connected to the end of each connection structure away from the power distribution module 2, a circuit breaker 30 is welded to the bottom of the inner cavity of the wire box 3, a plurality of connectors 33 are plugged on one side of the circuit breaker 30, and an end of each connector 33 away from the circuit breaker 30 is fixedly connected to the wire 13 corresponding to the position, racks 4 are fixedly installed on both sides of the power distribution module 2, a gear 5 is meshed on the side of each rack 4 away from the power distribution module 2, a gear rod 6 is fixedly installed on the inner side wall of each gear 5, and the upper end of the gear rod 6 is rotatably connected to the power distribution shell 1, a gear 2 7 is fixedly installed on the lower end of each gear rod 6, and a rack 2 8 is meshed on the side of each gear 2 7 away from the power distribution module 2;

[0036] The inner wall of the wire box 3 is slidably connected with a turning rod 9, the lower end of the turning rod 9 is rotatably connected with a guide wheel 10, and the outer surface of the guide wheel 10 contacts the wire 13, both ends of the turning rod 9 are fixedly connected with the corresponding rack 8, the side of the turning rod 9 close to the distribution module 2 is rotatably connected with a wire blocking plate 11, the side surface of the upper end of the wire blocking plate 11 is slidably connected with a pressing plate 31, and a spring 2 32 is fixedly installed between the pressing plate 31 and the wire blocking plate 11.

[0037] Specifically, the inner wall of the power distribution shell 1 is provided with a partition block, the power distribution module 2 slides on the upper end of the partition block, the wire box 3 slides on the lower end of the partition block, the power distribution module 2 and the wire box 3 are not in contact, the turning rod 9 is connected to the wire baffle 11 through a torsion spring shaft, and the initial state of the torsion spring shaft makes the wire baffle 11 appear vertically placed, and as Figure 2 As shown, each wire baffle 11 is placed between two wires 13 to separate each wire 13 so as not to contact each other. When the distribution module 2 is pushed into the interior of the distribution shell 1, the gear 5 is driven to rotate through the rack 4, and the gear 5 drives the gear rod 6 to rotate. The gear rod 6 then drives the rack 28 to slide toward the distribution module 2 through the gear 27. When the rack 28 slides, the turning rod 9, the guide wheel 10 and the wire baffle 11 slide synchronously toward the distribution module 2. During the sliding process, the pressing plate 31 on the outer surface of the wire baffle 11 can contact the side surface of the connecting structure, and the spring 2 32 prevents hard contact. When the guide wheel 10 slides, the lower surface of the guide wheel 10 will contact the wire 13. The guide wheel 10 can rotate to reduce the friction between the two. At the same time, as the guide wheel 10 slides, the wire 13 can be bent into a horizontal U-shape, so that when the distribution module 2 is retracted into the interior of the distribution shell 1, the wire 13 can be reasonably folded to reduce space waste.

[0038] The connecting structure includes a plug-in column 17, an outer wall of the plug-in column 17 is provided with a clamping groove 18, an inner wall of the plug-in column 17 is plugged with a plug-in rod 20, an end of the plug-in rod 20 away from the plug-in column 17 is fixedly installed with a transfer column 19, and the end of the transfer column 19 away from the plug-in rod 20 is fixedly connected to the wire 13, and two symmetrically distributed torsion spring rods 23 are fixedly connected on both sides of the transfer column 19, and the torsion spring rod 23 is rotatably connected to the side of the plug-in column 17 close to the plug-in column 17. The L-shaped clamping block 24 is provided with a barb in the direction close to the clamping groove 18, and the L-shaped clamping block 24 can be clamped with the clamping groove 18, and the L-shaped clamping block 24 is pushed toward the plug-in column 17 so that the hypotenuse on the barb of the L-shaped clamping block 24 contacts the side surface of the clamping groove 18, thereby pushing the L-shaped clamping block 24 to both sides of the plug-in column 17, and then continuing to push can The L-shaped clamping block 24 is clamped on the inner wall of the clamping groove 18, and the outer side wall of the adapter column 19 is fixedly installed with a mounting shell 21, and the inner side wall of the mounting shell 21 is penetrated with two oppositely distributed sliding grooves 29, and the torsion spring rod 23 is rotatably connected with a driven inclined block 25 on the side away from the L-shaped clamping block 24, and the driven inclined block 25 is fixedly connected to the L-shaped clamping block 24, and the outer side wall of the mounting shell 21 is rotatably connected with a rotating ring 22, and the inner side wall of the rotating ring 22 is fixedly installed with two symmetrically distributed connecting blocks 27, and each connecting block 27 is movably connected to the corresponding sliding groove 29, and each connecting block 27 is fixedly installed with a driving inclined block 26 on the side close to the adapter column 19, and each driving inclined block 26 conflicts with the corresponding driven inclined block 25, and a spring 28 is fixedly installed between the outer side wall of the connecting block 27 and the inner side wall of the sliding groove 29.

[0039] Specifically, Figure 8 As shown, the driven inclined block 25 and the L-shaped clamping block 1 24 are rotatably connected with the torsion spring rod 23, and the connection point is the torsion spring shaft. When the driven inclined block 25 rotates toward the direction of the transfer column 19, the L-shaped clamping block 1 24 will be synchronously driven and lifted, so that the barb on the L-shaped clamping block 1 24 is separated from the clamping groove 18. If one side of the driven inclined block 25 is no longer subject to the driving force, the torsion spring shaft of the torsion spring rod 23 is reset, and the L-shaped clamping block 1 24 is driven to be clamped on the plug-in column 17 again, so that the barb on the driven inclined block 25 is clamped in the groove of the clamping groove 18 again.

[0040] The rotating ring 22 can be rotated to drive the connecting block 27 to move in the sliding groove 29, and the connecting block 27 drives the driving bevel block 26 to contact one side of the driven bevel block 25. The surfaces of the driven bevel block 25 and the driving bevel block 26 that contact each other are both provided with beveled edges. When the driving bevel block 26 slides, the beveled edges can push the driven bevel block 25 to rotate toward the transfer column 19. At the same time, the driven bevel block 25 drives the L-shaped clamping block 24 to rotate together, so that the underhook of the L-shaped clamping block 24 is separated from the groove of the clamping groove 18.

[0041] Among them, a connecting plate 34 is fixedly installed on the side of each connecting head 33 close to the wire 13, and a spring four 41 is fixedly installed on the side of each connecting plate 34 close to the circuit breaker 30, and the spring four 41 is sleeved on the outer wall of the connecting head 33. When the connecting head 33 and the circuit breaker 30 are inserted and connected, the connecting plate 34 will resist the spring four 41, so that the spring four 41 is compressed.

[0042] Among them, two symmetrically distributed L-shaped clamping blocks 35 are fixedly installed on both sides of each connecting plate 34, and a plurality of square grooves are provided on the outer surface of the circuit breaker 30 near the L-shaped clamping block 35, and each square groove can be slidably connected with the L-shaped clamping block 35 at the corresponding position. A plurality of vertical grooves are provided inside the circuit breaker 30, and each vertical groove is connected with the square groove at the corresponding position. An arc edge rod 36 is slidably connected in the vertical groove, and an arc edge is provided on the side of the arc edge rod 36 near the L-shaped clamping block 35, and a spring 37 is fixedly installed between the upper end of the arc edge rod 36 and the inner cavity top of the vertical groove, and an empty groove 38 is provided on the side of the arc edge rod 36 near the L-shaped clamping block 35.

[0043] Specifically, Fig.10 As shown, the end of the L-shaped clamping block 35 away from the connecting plate 34 is equipped with a barb, and the barb is positioned toward the arc edge rod 36, and can contact the side surface of the arc edge rod 36. The L-shaped clamping block 35 has a certain degree of ductility. When the L-shaped clamping block 35 is inserted into the square groove, the barb on the L-shaped clamping block 35 will contact the arc edge rod 36, and then the arc edge of one side of the arc edge rod 36 will contact, so that the L-shaped clamping block 35 will bend to a certain extent, so that the barb of the circuit breaker 30 can turn over the arc edge rod 36, and then the straight edge of the barb contacts the side surface of the arc edge rod 36, so that the L-shaped clamping block 35 is stuck in the square groove, and the elastic potential energy of the spring 41 cannot be released.

[0044] like Fig.11As shown, the arc edge rod 36 can slide upward. When the arc edge rod 36 slides upward, the empty slot 38 will slide to one side of the L-shaped clamping block 35. The notch of the empty slot 38 is larger than the hook of the L-shaped clamping block 35. When the empty slot 38 slides to one side of the L-shaped clamping block 35, the arc edge rod 36 will no longer resist the hook of the L-shaped clamping block 35, so that the spring 41 can push the connecting plate 34, and the connecting plate 34 drives the connecting head 33 to be pulled out from one side of the circuit breaker 30.

[0045] Among them, a sliding groove 2 39 is opened inside the circuit breaker 30, and the inner side wall of the sliding groove 2 39 is slidably connected with a bevel rod 40, and the upper end of the bevel rod 40 is fixedly connected to the arc rod 36. A plurality of sliding grooves 3 42 are opened on the outer side wall of the circuit breaker 30, and the sliding groove 3 42 is located in the middle of every two connecting heads 33. A sliding bevel block 43 is slidably connected to the inner side wall of the sliding groove 3 42, and the side of the sliding bevel block 43 close to the circuit breaker 30 is in contact with the bevel of the bevel rod 40, and a spring 5 44 is fixedly installed between the sliding bevel block 43 and the inner side wall of the sliding groove 3 42.

[0046] Specifically, the contact surfaces of the bevel rod 40 and the sliding bevel block 43 are both provided with bevels. When the sliding bevel block 43 slides toward the direction of the circuit breaker 30, the sliding bevel block 43 will resist and push the bevel rod 40, causing the bevel rod 40 to slide upward. At the same time, the sliding of the bevel rod 40 drives the arc rod 36 to slide upward together. The spring three 37 is used to reset the arc rod 36 when the arc rod 36 is no longer pushed.

[0047] Among them, two positioning columns 50 are fixedly installed on both sides of the wire box 3, and the outer wall of each positioning column 50 is slidably connected with a slider 12. The outer wall of the positioning column 50 is sleeved with a spring eight 51, and a guide wheel two 121 is rotatably connected between the two sliders 12, and the outer surface of the guide wheel two 121 is in contact with the wire 13. The outer wall of the wire box 3 close to the slider 12 is rotatably connected with a winding wheel 14, and the outer wall of the winding wheel 14 is sleeved with a connecting rope, and one end of the connecting rope is fixedly connected to the slider 12. A gear three 15 is fixedly installed on the side of the winding wheel 14 away from the wire box 3, and a rack three 16 is meshed at the lower end of the gear three 15, and the rack three 16 is fixedly connected to the inner wall of the distribution shell 1.

[0048] Among them, the lower end of each baffle plate 11 is slidably connected to a sliding rod 45, and the upper end of each sliding rod 45 is fixedly installed with a spring six 46. The lower end of each sliding rod 45 is rotatably connected to a baffle plate 2 49, and each baffle plate 2 49 can conflict with the beveled edge rod 40 at the corresponding position. The sliding rod 45 is slidably connected to a conflicting block 48 on the side close to the guide wheel 2 121. Both sides of the conflicting block 48 are provided with beveled edges. When the conflicting block 48 is pushed out by the spring seven 47, the beveled edge will not conflict with the outer side wall of the spring six 46. When the conflicting block 48 further slides into the inside of the spring seven 47, the beveled edge will conflict with the outer side wall of the baffle plate 11, and then the thrust of the spring six 46 makes the beveled edge of the conflicting block 48 and the baffle plate 11 contact each other. 1, thereby allowing the abutment block 48 to slide further into the interior of the sliding rod 45. When the abutment block 48 completely slides into the interior of the sliding rod 45, the sliding rod 45 will be pushed out from the wire baffle plate 11 to the interior by the spring six 46. A spring seven 47 is fixedly installed between the abutment block 48 and the sliding rod 45. A slot corresponding to the position of the abutment block 48 is provided on the outer wall of the spring six 46, and the slot is slidably connected to the abutment block 48. When the guide wheel two 121 is no longer pushing the wire baffle plate one 11, the elastic restoring force of the torsion spring between the wire baffle plate one 11 and the turning rod 9 causes the wire baffle plate one 11 to rotate and reset. At the same time, the sliding rod 45 is pushed back into the wire baffle plate one 11 through the abutment between the inner cavity of the power distribution module 2 and the wire baffle plate two 49.

[0049] Specifically, Figure 5As shown, the guide wheel 2 121 contacts the wire 13 and limits the wire 13. The wire 13 is bent by sliding the guide wheel 10, so that the redundant part of the wire 13 is pressed into a horizontal U-shape, and the wire 13 is stored in a reasonable space to prevent the wires 13 from being staggered and overlapped. At the same time, when the wire box 3 is pulled out in a direction away from the distribution shell 1, the gear 3 15 will drive the winding wheel 14 to rotate by meshing with the rack 3 16. The winding wheel 14 releases the wire during its rotation, and then the wire is released by the spring. The elastic restoring force of the spring 8 51 pushes the slider 12 to slide, and the sliding of the slider 12 drives the guide wheel 2 121 to move. The movement of the guide wheel 2 121 releases the wire 13 that is in contact with it, so that when the line box 3 is pulled out of the distribution shell 1, the wire 13 will not be too tight. Then, when the guide wheel 2 121 slides, it will contact the contact block 48, so that the contact block 48 is partially pushed into the slot on the sliding rod 45, and then the contact block 48 is further slid to the sliding rod by the thrust of the spring 6 46. 45, so that the resistance block 48 can be pushed out of the inside of the wire baffle plate 11 by the spring six 46, and at the same time, the wire baffle plate 11 will be driven to rotate around the turning rod 9 during the sliding of the guide wheel 2 121, and the torsion spring shaft between the wire baffle plate 11 and the turning rod 9 will store elastic potential energy. During the process of the wire box 3 being drawn out, the wire 13 will be in a tilted state, and at the same time, the wire baffle plate 11 will be pushed to tilt synchronously with the wire 13, thereby limiting the wire 13 to prevent the wire 13 from being staggered and overlapped, and the wire baffle plate 11 is tilted The sliding rod 45 can slide out from the wire baffle plate 11. When the distribution module 2 is pulled out further, the wire baffle plate 2 49 will contact the sliding bevel block 43 and push the sliding bevel block 43 to slide in the direction of the circuit breaker 30, so that the L-shaped clamping block 2 35 is no longer stuck out. The connecting plate 34 is pushed by the spring 41, and the connecting plate 34 drives the connecting head 33 to be pulled out from the circuit breaker 30, so that the connecting head 33 can be quickly and safely pulled out without pulling the wire 13, thereby achieving safe and rapid power off.

[0050] Working principle: the distribution module 2 is pushed into the distribution shell 1, so that the rack 14 drives the gear 2 7 to rotate, thereby driving the turning rod 9 to slide in the direction of the distribution module 2. While the distribution module 2 slides, it drives the guide wheel 10 to fold the wires 13 pulled out by the distribution module 2 into a horizontal U shape, so that when the wires 13 are pulled out and pulled back into the wire box 3, the wires 13 will not be scattered. At the same time, the wire baffle 11 slides with the turning rod 9, so that the wires 13 are limited when they are folded, preventing multiple wires 13 from overlapping, thereby shortening the distance that the wires 13 can be pulled out after overlapping, making it impossible to pull out the distribution module 2;

[0051] Next, the L-shaped clamping block 24 is driven to contact the plug-in column 17 by pushing the mounting shell 21, so that the L-shaped clamping block 24 is unfolded and clamped on the inner wall of the clamping groove 18. When the plug-in rod 20 needs to be pulled out, the driving bevel block 26 is driven to contact the driven bevel block 25 by rotating the rotating ring 22, so that the driven bevel block 25 and the L-shaped clamping block 24 start to rotate slightly, so that the L-shaped clamping block 24 is separated from the inner wall of the clamping groove 18, and then the plug-in rod 20 can be pulled out from the plug-in column 1 7 is pulled out from the inside, and at the same time, the wire blocking plate 11 moves toward the direction of the power distribution module 2, so that the pressing plate 31 contacts with one side surface of the mounting shell 21, so that a second thrust is applied to the L-shaped clamping block 24 to prevent the L-shaped clamping block 24 from not being clamped in the clamping groove 18. If the clamping is completed, the pressing plate 31 slides on the inner side of the wire blocking plate 11, and the spring 2 32 is compressed, thereby storing elastic potential energy, and continuously contacts with the side surface of the mounting shell 21 to prevent the plug-in rod 20 from accidentally falling off;

[0052] Finally, when the wire box 3 is pulled out from the interior of the distribution shell 1, the rack three 16 drives the gear three 15 to rotate, so that the winding wheel 14 unwinds, and the guide wheel two 121 is pushed to slide in the direction of the circuit breaker 30 by the spring eight 51. When the guide wheel two 121 slides, a part of the folded wire 13 will be released, so that the wire 13 will not be too tight when the wire box 3 is pulled out. At the same time, the guide wheel two 121 slides and pushes the side surface of the wire baffle plate one 11 so that the wire baffle plate one 11 starts to rotate. At the same time, the sliding rod 45 is no longer stuck by the resistance block 48 and slides away from the wire baffle plate one 11. When the distance that the wire box 3 is pulled out is too large, the wire baffle plate two 49 is pushed by the sliding rod 45 to resist and push the sliding inclined block 43. The sliding inclined block 43 pushes the empty slot 38 to slide upward, so that the L-shaped clamping block two 35 is no longer stuck by the arc edge rod 36, and the elastic potential energy of the spring four 41 is released to push the connector 33 out of the circuit breaker 30 to the inside, thereby achieving quick and safe power off.
