Description

Technical Field

[0001] The invention relates to the technical field of grid-connected power generation vehicles, and in particular to a grid-connected quick access mechanism for power generation vehicles. Background Art

[0002] In extreme weather such as rain, snow, and strong winds, the installed cables may break, causing power outages for users. In order to ensure users' normal electricity needs, generator trucks are usually activated when cables break, and the cables are connected to the generator trucks to supply power to users.

[0003] When the cable is connected to the generator car, an access mechanism (or device) is required to electrically connect the two. For example, the patent application with publication number CN116646779B discloses a wall-mounted generator car quick access device, including a mounting plate and a limiting mechanism, a fixing plate is fixedly connected to the right side of the mounting plate, a groove is provided on the right side of the fixing plate, a first threaded rod is rotatably connected in the groove, a first threaded sleeve is meshedly connected on the first threaded rod, a connecting plate is fixedly connected to one side of the first threaded sleeve, a transparent waterproof cover is fixedly connected to the right side of the connecting plate, and the lower end of the transparent waterproof cover is set to an open state. The prior art can drive the second threaded rod to rotate through the matching arrangement of the handle, the worm and the worm gear, the second threaded rod can drive the push plate to move through the second cavity and abut against the slot, the fixing block can be limited and fixed by the pin and the slot, and the fixing block can prevent the plug from loosening and falling off, thereby avoiding power supply interruption and not affecting the normal use of electricity.

[0004] However, the above-mentioned prior art still has some defects in the process of quickly connecting the power generation vehicle to the cable: the above-mentioned patent application electrically connects the power generation vehicle and the cable through a plug and a socket, but the cable is in a broken state during actual use. The above-mentioned prior art needs to be electrically connected to the broken cable and the plug before it can be used, and its applicability is poor. The cable can only be connected to the power generation vehicle after forming a new circuit through the plug and the socket in turn. This process takes a long time, and there are too many electrical connection points in the newly formed circuit, which may easily cause leakage or circuit breaking, and the electrical connection effect is not good.

[0005] Based on this, and in accordance with the above-mentioned viewpoints, the existing technology still has room for improvement in the way in which power generation vehicles can quickly access cables. Summary of the invention

DETAILED DESCRIPTION

[0045] The following is combined with Figures 1 to 9 The present invention is described in further detail.

[0046] The embodiment of the present invention discloses a quick grid-connection mechanism for a power generation vehicle, wherein a cable is directly inserted into an access mechanism corresponding to the power generation vehicle, thereby reducing the tediousness of the process of connecting the cable to the power generation vehicle and avoiding the possibility of power failure at the cable connection point.

[0047] Embodiment 1: See also Figure 1 and Figure 2 A quick grid-connection mechanism for a power generation vehicle comprises an annular frame 1, a plurality of groups of fixed protrusions 2 are evenly installed on the circumferential surface of the annular frame 1, each group of fixed protrusions 2 are symmetrically distributed along the radial direction of the annular frame 1, a hinge shaft is installed between each group of fixed protrusions 2, and a V-shaped locking plate 3 is installed on the hinge shaft.

[0048] The opening of the locking plate 3 faces the axis direction of the annular frame 1, and the turning part of the locking plate 3 is connected to the spring hinge shaft.

[0049] The annular frame 1 is provided with a horizontal frame 4 extending along its axial direction, and the horizontal frame 4 is provided with a vertical frame 5 perpendicular thereto, and the vertical frame 5 is provided with an electrical contact 6, and the electrical contact 6 is provided with a conductive slot 61 electrically connected to the cable (see Fig. 9).

[0050] The above-mentioned power generation vehicle grid-connected quick access mechanism is provided with two, one for connecting the live wire and the other for connecting the neutral wire, and the electrical contacts 6 are electrically connected to the existing power generation vehicle.

[0051] The cable can be directly inserted into the conductive slot 61 and form a closed loop with the generator vehicle. The cable is energized at this time, and then the cable is locked and limited by the locking plate 3 to prevent the cable from falling off from the conductive slot 61. The above method can effectively shorten the time for the generator vehicle to access the cable and improve the cable power-on efficiency. In addition, there is only one connection point between the cable and the electrical contact 6 in the formed closed loop, which reduces the possibility of leakage and power failure in the closed loop.

[0052] See also Figure 2 A driving assembly 31 for controlling the opening and closing of the locking plate 3 is provided on the horizontal frame 4. The driving assembly 31 includes: a moving disc 311, which is slidably arranged on the horizontal frame 4 and has a through groove in the middle. One end of the locking plate 3 close to the vertical frame 5 is slidably matched with the moving disc 311.

[0053] The vertical protrusion 312 is arranged on the horizontal frame 4. A threaded rod 313 extending along the length direction of the horizontal frame 4 is rotatably installed on the vertical protrusion 312, and one end of the threaded rod 313 away from the vertical protrusion 312 is installed on the moving disc 311 by a threaded connection.

[0054] The cable is passed through the through slot and the insulation layer at the end of the cable is cut open to expose the metal wire inside the cable, and the metal wire is placed inside the conductive slot 61. At this time, the cable is located on the axis of the through slot and the annular frame 1. During specific operation, the threaded rod 313 is driven to rotate by an external drive (motor, etc.). During the rotation of the threaded rod 313, the movable disc 311 is driven to move toward the side of the vertical frame 5 on the horizontal frame 4. During the movement of the movable disc 311, it slides along the end of the locking plate 3 close to the vertical frame 5. At this time, the inclined section of the locking plate 3 close to the side of the vertical frame 5 is opened. At this time, the corner of the locking plate 3 rotates around the hinge axis, and the angle of the locking plate 3 away from the vertical frame 5 gradually decreases and approaches the side of the cable. The end of the locking plate 3 away from the vertical frame 5 abuts against the cable when approaching the cable, and the ends of the locking plate 3 away from the vertical frame 5 cooperate with each other to lock the cable, thereby ensuring that the cable will not fall off the conductive slot 61 during the electrical connection between the cable and the conductive slot 61.

[0055] See also Figure 2 and Figure 3In order to prevent leakage and power failure from occurring when the connection between the cable and the electrical contact 6 comes into contact with rainwater, the insulating component 41 designed in the present invention can protect the connection between the cable and the electrical contact 6, so that the connection is isolated from external rainwater. Specifically, the horizontal frame 4 is also equipped with an insulating component 41 for isolating the connection between the electrical contact 6 and the cable from the external environment. The insulating component 41 includes: a movable frame 411, which is slidably arranged on the horizontal frame 4, and a ring plate 412 is installed at one end of the movable frame 411 away from the horizontal frame 4.

[0056] The sliding block 413 is slidably disposed on the inner wall of the annular plate 412 , and a winding shaft 414 is installed on a side of the sliding block 413 away from the vertical frame 5 .

[0057] One end of the insulating strip 415 is mounted on the horizontal frame 4 , and the other end away from the horizontal frame 4 is wound on the winding shaft 414 .

[0058] The reciprocating assembly 42 is disposed on the vertical protrusion 312 and is used to drive the moving frame 411 to reciprocate along the length direction of the horizontal frame 4, so that the insulating strip 415 can be wound with multiple layers at the connection between the electrical contact 6 and the cable.

[0059] The insulating strip 415 is offset at a certain angle to avoid the possibility of collision between the winding shaft 414 and the insulating strip 415 after one circumferential rotation. During operation, the mobile frame 411 is driven by an external drive to move. During the movement of the mobile frame 411, the annular plate 412 is driven to move toward the side of the vertical frame 5. During the movement of the annular plate 412, the sliding block 413 synchronously moves along the inner wall of the annular plate 412. During the movement of the sliding block 413, the insulating strip 415 is driven to spread out. At this time, the insulating strip 415 is wound along the cable. When the insulating strip 415 is wound around the cable to the connection between the cable and the electrical contact 6, the insulating strip 415 continues to be wound until it passes over the connection between the cable and the electrical contact 6. Then, the insulating strip 415 wound on the cable and the electrical contact 6 can isolate the exposed metal wire from the electrical contact 6 and the outside, thereby preventing rainwater from entering the connection between the cable and the electrical contact 6, causing the above-mentioned closed loop to short-circuit, and at the same time avoiding leakage.

[0060] See also Figure 3 In order to ensure that the insulating strip 415 can effectively isolate the connection between the cable and the electrical contact 6 and the external environment, the reciprocating assembly 42 provided by the present invention can drive the annular plate 412 to reciprocate along the length direction of the horizontal frame 4. Specifically, the reciprocating assembly 42 includes: a bidirectional screw 421, which is installed on the vertical protrusion 312 through a bearing, and one end of the bidirectional screw 421 away from the vertical protrusion 312 is installed on the moving frame 411 through a threaded connection.

[0061] Gear 1 422 is mounted on the threaded rod 313 , and gear 2 423 meshing with gear 1 422 is mounted on the bidirectional screw rod 421 .

[0062] During specific operation, the threaded rod 313 rotates through the mutual meshing of gear 1 422 and gear 2 423 to drive the bidirectional screw 421 to rotate. During the rotation of the bidirectional screw 421, the moving frame 411 is first driven to move toward one side of the vertical frame 5. When the moving frame 411 moves to the right end of the bidirectional screw 421, the moving frame 411 is reset. When the moving frame 411 is reset to the starting position, it moves toward the side of the vertical frame 5 again. Then, the moving frame 411 can be driven to reciprocate along the horizontal frame 4 in the above manner. During the movement of the moving frame 411, the annular plate 412 can be driven to reciprocate. Then, during the reciprocating movement of the annular plate 412 along the horizontal frame 4, the sliding block 413 drives the winding shaft 414 to rotate circumferentially around the annular plate 412, so that the winding shaft 414 can wrap the connection between the cable and the electrical contact 6 with multiple layers when releasing the insulating strip 415, thereby further improving the insulation effect of the connection between the cable and the electrical contact 6.

[0063] At the same time, the insulating strip 415 can connect the cable and the electrical contact 6 so that the cable will not be separated from the conductive slot 61 , thereby improving the electrical connection effect between the cable and the electrical contact 6 .

[0064] The mutual engagement of gear 1 422 and gear 2 423 can reduce the use of existing drives and effectively save costs. The diameter of gear 1 422 is larger than the diameter of gear 2 423. The purpose is to allow the bidirectional screw 421 to rotate multiple times when the threaded rod 313 rotates one circle, thereby increasing the number of times the movable frame 411 drives the annular plate 412 to reciprocate, thereby increasing the number of insulating layers of the insulating strip 415 wrapped around the connection between the cable and the electrical contact 6, making the insulating layer thicker, and effectively isolating the connection between the cable and the electrical contact 6 from the external environment.

[0065] See also Figure 4 and Figure 5 In order to improve the stability of the cable during electrical connection and ensure that the cable will not fall off from the conductive groove 61, the locking assembly 11 provided by the present invention can increase the stability of the cable. Specifically, a locking assembly 11 is installed on the annular frame 1, and the locking assembly 11 includes: an elastic telescopic rod 111, which is provided with multiple and circumferentially uniformly installed on the inner wall of the annular frame 1.

[0066] The push rod 112 is installed on the telescopic end of the elastic telescopic rod 111 , and a rubber block 113 is installed at one end of the push rod 112 away from the elastic telescopic rod 111 .

[0067] The linkage assembly 12 is installed on the annular frame 1 and is used to pull the telescopic end of the elastic telescopic rod 111 to move.

[0068] The linkage assembly 12 includes: a plurality of fixed rods 121 , which are evenly installed on the inner wall of the annular frame 1 on one side close to the moving disc 311 .

[0069] The fixed pulley 122 is installed at one end of the fixing rod 121 away from the annular frame 1 .

[0070] A traction rope 123 , one end of which is mounted on the telescopic end of the elastic telescopic rod 111 , and one end of the traction rope 123 away from the elastic telescopic rod 111 passes around the fixed pulley 122 and is mounted on the moving disc 311 .

[0071] The fixed pulley 122 can change the traction direction of the traction rope 123, so that when the traction rope 123 is subjected to the force toward one side of the vertical frame 5, the fixed pulley 122 changes the force and drives the elastic telescopic rod 111 to move downward. During specific operation, the movable disc 311 drives the traction rope 123 to move toward the side of the vertical frame 5 during the movement. During the movement of the traction rope 123, the telescopic end of the elastic telescopic rod 111 is driven to move toward the side of the cable through the fixed pulley 122. At this time, the telescopic end of the elastic telescopic rod 111 drives the pushing rod 112 to move toward the side of the cable. During the movement of the pushing rod 112, the rubber block 113 is driven to come close to the cable, and then the pushing rod 112 and the rubber block 113 cooperate with each other to lock the cable, and further limit and fix the cable.

[0072] The rubber block 113 can press against the cable during the movement. The rubber block 113 is deformed to increase the contact area between the rubber block 113 and the cable, thereby increasing the friction between the rubber block 113 and the cable, further reducing the possibility of relative sliding or rotation of the cable. At the same time, due to the good deformation ability of the rubber block 113, the rubber block 113 can also fix and limit cables of different diameters.

[0073] At the same time, the driving force provided by the moving disc 311 during movement is utilized, and the cable is locked and limited through the above linkage mode without external drive, thereby saving costs and improving the stability of the cable when electrically connected to the power generation vehicle.

[0074] See also Figure 6 and Figure 7 In order to further improve the stability of the cable during electrical connection and ensure that the cable will not fall off the conductive groove 61, the locking assembly 32 provided by the present invention can further increase the stability of the cable. Specifically, a locking assembly 32 is installed on the movable disc 311, and the locking assembly 32 includes: an annular groove 321, which is opened inside the movable disc 311, and a plurality of movable grooves 322 that penetrate the annular groove 321 are evenly opened along the circumference of the through groove.

[0075] The movable plate 323 is slidably disposed inside the movable groove 322 , and a rubber connecting block 324 is installed at one end of the movable plate 323 away from the annular groove 321 .

[0076] At the top of the annular frame 1, a relief plate 325 is installed corresponding to the top of one end of the locking plate 3 close to the vertical frame 5. An air cylinder 326 is installed on the moving disc 311, and the air outlet of the air cylinder 326 is connected to the annular groove 321 in a through manner. The telescopic end of the air cylinder 326 is slidably arranged on the relief plate 325.

[0077] Among them, a sealing arrangement is provided between the moving plate 323 and the moving groove 322, that is, gas will not flow out from the gap between the moving plate 323 and the moving groove 322. During specific operation, when the moving disc 311 moves, it drives the air cylinder 326 to move. During the movement of the air cylinder 326, its telescopic end abuts against the relief plate 325. Then, the air cylinder 326 pumps gas into the annular groove 321 at this time. The gas inside the annular groove 321 expands, and the gas enters the moving groove 322 through the annular groove 321. After the gas expands inside the moving groove 322, it drives the moving plate 323 to move towards the cable side. During the movement of the moving plate 323, it drives the rubber connecting block 324 to approach the cable. Then, the moving plate 323 can lock the cable through the rubber connecting block 324, further limit and fix the cable, and prevent the cable from sliding relatively.

[0078] Among them, the rubber connecting block 324 can press against the cable during movement. At this time, the rubber connecting block 324 deforms, thereby increasing its contact area with the cable, increasing the friction force between the rubber connecting block 324 and the cable, further reducing the possibility of the cable sliding or rotating relatively. At the same time, due to the good deformation ability of the rubber connecting block 324, the rubber block 113 can also fix and limit cables with different diameters.

[0079] Since the locking plate 3 rotates around the hinge shaft, the telescopic end of the air cylinder 326 is in sliding fit with the relief plate 325, preventing the telescopic end of the air cylinder 326 from still being able to cooperate with the relief plate 325 after the relief plate 325 rotates a certain angle, and the relief plate 325 can still hinder the telescopic end of the air cylinder 326.

[0080] Refer to Figure 8 , a third locking component 43 is installed on the horizontal frame 4. The third locking component 43 includes: a locking frame 431, which is a V-shaped structure with an opening facing the horizontal frame 4, and the two inclined sections of the locking frame 431 are installed on the horizontal frame 4.

[0081] A lifting frame 432, which is arranged between the two inclined sections of the locking frame 431 and has an arc-shaped structure.

[0082] Two connecting frames 433, which are in a U-shaped structure with an opening downward, and are symmetrically installed on the lifting frame 432 along the length direction of the lifting frame 432.

[0083] A linkage plate 434, which is installed on the locking plate 3 at the top of the annular frame 1.

[0084] The connecting rope 435 is in an inverted Y-shaped structure. The two inclined sections of the connecting rope 435 are respectively installed on the connecting frame 433 on the corresponding side, and the vertical section of the connecting rope 435 is installed on the linkage plate 434.

[0085] The locking frame 431 is configured as an arc structure at its bend, and the arc structure of the locking frame 431, the annular frame 1, the through slot, the annular plate 412 and the conductive slot 61 are coaxial, and the cable passes through the center of the through slot, the center of the arc structure of the locking frame 431 and the center of the annular plate 412 from the center of the annular frame 1 in sequence and then enters the conductive slot 61. When working, the cable is located between the arc structure of the locking frame 431 and the lifting frame 432 when passing through the locking frame 431, and the cable passes between the vertical sections corresponding to each arc frame, and the locking frame 431 at the top of the annular frame 1 is During the upward movement of plate 3, the linkage plate 434 is driven upward by the connecting rope 435. During the upward movement of the linkage plate 434, the connecting frame 433 is driven upward by the connecting rope 435. During the upward movement of the connecting frame 433, the lifting frame 432 is driven upward. During the upward movement of the lifting frame 432, the cable is in contact with the arc structure on the lifting frame 432, and the cable is pressed against the arc structure of the locking frame 431. Then, the arc structures of the lifting frame 432 and the locking frame 431 cooperate with each other to further limit and fix the cable to ensure that the cable does not move relative to each other.

[0086] The connecting rope 435 is arranged in a Y-shaped structure so that its inclined section and vertical section can rotate with multiple degrees of freedom, thereby ensuring that the lifting frame 432 is always in a horizontal state driven by the linkage plate 434, thereby ensuring that the arc structure of the lifting frame 432 is always in contact with the cable, thereby increasing the contact area of ​​the lifting frame 432 with the cable, ensuring that there is sufficient friction between the cable and the lifting frame 432, and avoiding relative sliding of the cable on the lifting frame 432.

[0087] Therefore, the locking component 1 11, the locking component 2 32 and the locking component 3 43 cooperate with the locking plate 3 to perform multiple fixed limits on the cable, reduce the possibility of the cable detaching from the conductive groove 61, and improve the electrical connection effect of the power generation vehicle accessing the cable. The driving force for the above work is provided only through the linkage mode of the threaded rod 313 and the movable disc 311, which effectively reduces the use of existing drives and saves mechanism costs.

[0088] After the above steps are completed, the power of the generator car is turned on, and the connected cables can be energized.

[0089] Embodiment 2: Reference Fig. 9On the basis of the first embodiment, in severe weather such as heavy rain, snow and other severe weather, trees may make the road impassable for driving, and the power generation vehicle may not be able to enter the designated power generation area. The electrical connection line 52 can be used to enable the above-mentioned mechanism to enter the designated power generation area. Specifically, a cylinder 51 is rotatably sleeved on the vertical frame 5, and an electrical connection line 52 is wound around the cylinder 51.

[0090] The electric connecting line 52 is electrically connected to the power generation vehicle, and the end of the electric connecting line 52 away from the power generation vehicle is installed on the cylinder 51, and the cylinder 51 is electrically connected to the electric contact 6. This is the prior art, so the open circuit or leakage of the above-mentioned connection point is not considered. During specific work, the present invention is manually moved to the designated power generation area. During the moving process of the present invention, the cylinder 51 is rotated to release the electric connecting line 52, and then the power generation areas at different distances from the power generation vehicle can be powered. It has higher applicability. At the same time, the electric connecting line 52 can also adaptively compensate for the distance between the electric contact 6 and the cable to ensure smooth electrical connection between the electric contact 6 and the cable.

[0091] The implementation principle of the present invention is: (1): Pass the cable through the through slot and cut open the insulation layer at the end of the cable to expose the metal wire inside the cable, and place the metal wire inside the conductive slot 61. At this time, the cable is located on the axis of the through slot and the annular frame 1.

[0092] (2): The threaded rod 313 is driven to rotate by an external drive (motor, etc.). During the rotation of the threaded rod 313, the movable disc 311 is driven to move on the horizontal frame 4 toward the side of the vertical frame 5. During the movement of the movable disc 311, it slides along the end of the locking plate 3 close to the vertical frame 5. At this time, the inclined section of the locking plate 3 close to the side of the vertical frame 5 is opened. At this time, the corner of the locking plate 3 rotates around the hinge axis. The angle of the locking plate 3 away from the vertical frame 5 gradually decreases and approaches the cable side. The end of the locking plate 3 away from the vertical frame 5 abuts against the cable when approaching the cable. The sections of the locking plate 3 away from the vertical frame 5 cooperate with each other to lock the cable.

[0093] (3): The movable frame 411 is driven by an external drive to move. During the movement of the movable frame 411, the annular plate 412 is driven to move toward the side of the vertical frame 5. During the movement of the annular plate 412, the sliding block 413 is synchronously moved along the inner wall of the annular plate 412. During the movement of the sliding block 413, the insulating strip 415 is driven to spread out. At this time, the insulating strip 415 is wound along the cable. When the insulating strip 415 is wound around the cable to the connection between the cable and the electrical contact 6, the insulating strip 415 continues to be wound until it passes over the connection between the cable and the electrical contact 6. Then, the insulating strip 415 wound around the cable and the electrical contact 6 can isolate the exposed metal wire from the electrical contact 6 and the outside.

[0094] (4): The locking assembly 11, the locking assembly 2 32 and the locking assembly 3 43 cooperate with each other to lock and limit the cable again. After the above steps are completed, the power supply of the generator car is turned on, and the connected cable can be energized.

[0095] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates. In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
