Abstract
Description
Technical Field
[0001] The present invention relates to the technical field related to electric power, and in particular to a wire clamp mechanism for grid-connected power generation vehicles. Background Art
[0002] During the line construction and reconstruction process, in order to ensure the normal power supply for users in the non-operating section, the "stop-and-belt combination" construction method is usually adopted, that is, the reconstruction line section is shut down for construction, and the non-operating section line generates electricity on-site through the medium-voltage generator car. The operation of connecting the generator car to the non-operating section line is grid connection (the physical connection between the generator set or power plant (field, station) or direct-dispatch user and the power grid). In the process of connecting the generator car to the grid, wire clamps are usually required to connect the cables.
[0003] In the existing grid connection process, such as the Chinese patent with publication number CN212991369U, a compression-proof parallel groove wire clamp is disclosed, which includes: a parallel groove wire clamp; two connecting through holes, both of which are opened in the parallel groove wire clamp; two clamping devices, both of which are threadedly connected in the parallel groove wire clamp, and both of which include screws, and the ends of the two screws close to each other extend into the two connecting through holes respectively and are rotatably connected to clamping plates, and the ends of the two screws away from each other are fixedly connected to rotating handles; four limit devices.
[0004] In the above-mentioned prior art, the cable is fixed mainly by driving the clamping plate with a screw, and the anti-loosening effect is achieved by a limit device. However, the above-mentioned prior art does not take into account the need to control the torque when connecting the cable to ensure that the screws or bolts are tightened to the torque value recommended by the manufacturer. Over-tightening can cause damage to the cable or the wire clamp, while tightening too loose may cause poor contact of the cable. On the other hand, the wire clamp usually requires two to three screws, and the screws should be tightened to a uniform pressure to ensure that the pressure applied by the wire clamp to the cable is uniform to avoid local overpressure causing cable damage. In addition, the existing wire clamp requires two cables to be placed side by side before they can be installed and fixed. The cable itself is relatively thick and heavy, and it is not easy to adjust its position. It is easy to fall off between the wire clamps. In addition, the existing wire clamps wrap the cables tightly and lack heat dissipation space. When high current passes, the wire clamps and the wires will generate heat. Poor heat dissipation will cause the temperature to rise, causing material aging, damage or electrical performance degradation.
[0005] Based on this, there is still room for improvement in the above-mentioned prior art. Summary of the invention

A folding slot and a switching slot are provided in sequence from top to bottom at the lower part of the abutment block. The depth of the switching slot is deeper than that of the folding slot. In the initial state, the inner end of the sliding rod is against the folding slot.

During installation, it senses whether the load meets the standard. When the load reaches the standard, it limits the downward displacement of the fastener and displays a color mark for reminder, thereby establishing a clear standard for the installation torque of the fastener to avoid over-tightening or over-loosening. At the same time, the clear standard also allows multiple fasteners to be tightened to a position where the load is almost uniform, so that the cable is more evenly stressed and the cable is avoided. After the installation is completed, heat dissipation space is left for the cable to avoid the situation where the contact resistance between the wire clamp and the cable is increased due to high temperature, thereby affecting the electrical performance of the line connection, so that the contact resistance between the wire clamp and the cable is maintained at a low and stable level.

DETAILED DESCRIPTION
[0028] The following is combined with Figure 1-Figure 8 This application is described in further detail.
[0029] The embodiment of the present application discloses a wire clamp mechanism for grid-connected power generation vehicles, which pre-clamps the cable to assist personnel in positioning the cable, then senses the tightening load on the cable and instructs personnel to accurately install the cable with the load, making the installation more accurate.
[0030] Reference Figure 1 , Figure 2 As shown, a wire clamp mechanism for grid-connected power generation vehicle includes an upper fastener 1, a lower fastener 2, a bolt 3, a fastener 4, a clamping module 5, a linkage module 6, and a heat dissipation module 7. The lower fastener 2 and the upper fastener 1 are connected and matched by the bolt 3, and the fastener 4 and the bolt 3 are fastened and installed by threaded matching. The clamping module 5 is arranged in the upper fastener 1, and the clamping module 5 pre-clamps the cable. The linkage module 6 is arranged at the upper end of the upper fastener 1, and the linkage module 6 cooperates with the fastener 4 to sense and indicate the installation tightness between the upper fastener 1 and the lower fastener 2. The heat dissipation module 7 is arranged in the clamping module 5, and the heat dissipation module 7 assists in heat dissipation when the cable is working.
[0031] In the actual process of grid-connected wiring, the upper fastener 1 is buckled on the cable to be connected, and the clamping module 5 simply clamps and fixes the cable, then the lower fastener 2 is buckled on the cable, the bolt 3 is inserted between the upper fastener 1 and the lower fastener 2, and then the fastener 4 is tightened on the bolt 3. During the tightening process, the linkage module 6 triggers the clamping module 5 to release the simple clamping of the cable (the upper fastener 1 and the lower fastener 2 are switched to tighten and clamp the cable), the heat dissipation module 7 is triggered, and the heat dissipation module 7 partially exposes the cable to facilitate heat dissipation of the cable during operation. When the fastener 4 is tightened to a certain extent, the linkage module 6 senses that the load it bears reaches a specified value, thereby triggering the fastener 4 to indicate color, indicating that the fastener 4 has been installed. At the same time, the position between the fastener 4 and the upper fastener 1 is limited to avoid the situation where the cable swings in the air and causes the fastener 4 to loosen. The present application ensures convenient and stable grid-connected wiring through auxiliary clamping before installation, color indication during installation, and exposed heat dissipation after installation.
[0032] Reference Figure 3 , Figure 5 As shown, when connecting, the two cables need to be placed side by side before the upper fastener 1 and the lower fastener 2 can be fastened, but the cables are usually heavy and thick, and it is easy for the cables to fall off the upper fastener 1 and the lower fastener 2 by manpower alone. In order to initially clamp the cables and pre-fix the cables and the upper fastener 1 to facilitate the closing of the upper fastener 1 and the lower fastener 2, the present application is provided with a clamping module 5, which includes a clamping claw 51, a rotating shaft 52, a sliding rod 53, a connecting rod 54, and a locking mechanism 55. The clamping claw 51 is rotatably set in an installation groove opened on the bottom surface of the upper fastener 1 through the rotating shaft 52, and the installation groove is arc-shaped. The sliding rod 53 is slidably set in the installation groove. A spring three is connected between the sliding rod 53 and the installation groove. The spring three always keeps the sliding rod 53 pushing toward the middle. The two ends of the connecting rod 54 are respectively connected to the clamping claw 51 and the sliding rod 53 through a pin shaft, and the locking mechanism 55 is set in the upper fastener 1.
[0033] In the actual process of pre-clamping the cable, the upper fastener 1 is buckled on the cable, and the resistance block 551 is squeezed upward by the cable to make the inner end of the sliding rod 53 disengage from the gathering groove 553, and the sliding rod 53 is squeezed to slide in the direction away from the gathering groove 553. Under the action of the connecting rod 54, the clamping claw 51 rotates inward around the rotating shaft 52 and closes, thereby simply clamping the cable.
[0034] Reference Figure 6-Figure 8As shown, after the clamping claw 51 is closed to clamp the cable, it needs to be locked in position. At the same time, during subsequent disassembly, the clamping claw 51 is required to no longer clamp the cable. In order to achieve the staged clamping of the clamping claw 51, the present application is provided with a locking mechanism 55, which includes a resistance block 551, a lifting groove 552, a retracting groove 553, a switching groove 554, a fixing rod 555, a rotating rod 556, a guide pin 557, a guide groove 558, and a blocking plate 559. The resistance block 551 is slidably arranged in the installation groove up and down, and a lifting groove 552 that runs through the left and right is provided in the middle part of the resistance block 551, and a retracting groove 553 and a switching groove 554 are provided in sequence from top to bottom. The depth of the switching groove 554 is deeper than that of the retracting groove 553, and the inner end of the sliding rod 53 in the initial state is against In the retracted groove 553, the clamping claw 51 is in an outwardly rotated and opened state, which is convenient for the cable to enter. The fixed rod 555 is installed at the top of the installation groove, and the contact block 551 and the fixed rod 555 are slidably matched. A spring four is connected between the contact block 551 and the fixed rod 555, and the spring four plays a reset role. The rotating rod 556 is rotatably set at the lower end of the fixed rod 555, and the rotating rod 556 and the fixed rod 555 are slidably matched up and down. A guide pin 557 is installed on the outer periphery of the rotating rod 556, and the guide pin 557 is an elastic telescopic structure. A guide groove 558 that slides with the guide pin 557 is opened on the outer wall of the fixed rod 555. The blocking plate 559 is installed at the lower end of the rotating rod 556, and the blocking plate 559 is located in the lifting groove 552. The blocking plate 559 and the contact block 551 are mutually clamped.
[0035] Reference Figure 7 As shown, the guide groove 558 consists of an inclined groove and a straight groove. When the guide pin 557 moves in the inclined groove, the rotating rod 556 moves upward relative to the fixed rod 555 and rotates at the same time. When the guide pin 557 moves from the inclined groove to the straight groove, the movement of the rotating rod 556 in the up and down directions is restricted.
[0036] In the actual locking process, the guide pin 557 is squeezed when the contact block 551 moves upward, and the squeezed guide pin 557 slides in the guide groove 558, so that the rotating rod 556 moves upward synchronously with the contact block 551 and rotates at the same time. When the guide pin 557 moves into the straight groove, the movement of the guide pin 557 in the vertical direction is restricted, that is, the movement of the rotating rod 556 in the vertical direction is restricted, and the movement of the blocking plate 559 in the vertical direction is restricted. Since the blocking plate 559 and the contact block 551 are mutually engaged, the contact The block 551 cannot move downward (that is, the spring four cannot push the resistance block 551 to move downward and reset, but at this time the resistance block 551 can still move upward when subjected to an upward external force, and when the resistance block 551 moves upward, the guide pin 557 is squeezed and contracted, thereby allowing the resistance block 551 to continue to rise). Afterwards, when the fastener 4 is tightened, the linkage module 6 squeezes the lifting groove 552 to lift the resistance block 551 upward, so that the inner end of the sliding rod 53 corresponds to the position of the switching groove 554. Under the action of the spring three, the inner end of the sliding rod 53 moves into the switching groove 554. 54, under the action of the connecting rod 54, the clamping claw 51 rotates outward and opens, and no longer clamps the cable (at this time, the upper fastener 1 and the lower fastener 2 have been locked, and the clamping claw 51 is no longer needed for clamping), and the heat dissipation module 7 is triggered. On the other hand, when the linkage module 6 squeezes the lifting groove 552, the linkage module 6 eccentrically squeezes the blocking plate 559 to rotate the blocking plate 559, and the rotating rod 556 rotates with the blocking plate 559 (the rotation of the rotating rod 556 here is reversed compared to the rotation driven by the guide pin 557), so that the guide pin 557 is driven by the guide pin 557. 57 rotates from the straight groove into the inclined groove, so that the guide pin 557 is unlocked in the upward and downward directions. As the guide pin 557 moves in the inclined groove, the rotating rod 556 rotates in the opposite direction and moves downward to reset, and the blocking plate 559 moves downward to reset. The blocking plate no longer limits the downward movement of the interference block 551, but at this time the upper fastener 1 and the lower fastener 2 are already locked. At this time, the interference block 551 cannot move downward to reset due to the obstruction of the cable. Only when the upper fastener 1 and the lower fastener 2 are unlocked during subsequent disassembly, the cable is detached, and the interference block 551 can be reset normally.
[0037] Reference Figure 2 As shown, the fastener 4 includes a hexagonal nut 41 , a flange pressing block 42 , and a clamping mechanism 43 . The flange pressing block 42 is installed at the bottom of the hexagonal nut 41 , and the clamping mechanism 43 is arranged on the flange pressing block 42 .
[0038] Reference Figure 4As shown, the clamping mechanism 43 includes a movable ring 431, an embedded layer 432, a clamping block 433, and a clamping groove 434. The movable ring 431 is slidably arranged on the outer periphery of the flange pressing block 42 up and down. A spring 1 is connected between the movable ring 431 and the flange pressing block 42. The spring 1 maintains the position state of the movable ring 431 and has a reset function. The top of the inner wall of the movable ring 431 is provided with an embedded layer 432. The embedded layer 432 has a striking color for easy observation by personnel, thereby serving as a reminder. The upper end of the movable ring 431 in the initial state is flush with the flange pressing block 42. The movable ring 431 is The lower end exceeds the lower end surface of the flange pressing block 42. At this time, the embedded layer 432 is blocked and cannot be observed. Only when the movable ring 431 moves upward relative to the flange pressing block 42, the embedded layer 432 is exposed. The clamping block 433 is evenly slidingly arranged on the side wall of the movable ring 431 along the radial direction. A second spring is connected between the clamping block 433 and the movable ring 431. The second spring always pushes the clamping block 433 toward the flange pressing block 42. A chamfer is arranged on the side of the clamping block 433 close to the flange pressing block 42, and a clamping groove 434 corresponding to the position of the clamping block 433 is arranged on the flange pressing block 42.
[0039] Reference Figure 3 As shown, the linkage module 6 includes a pressure plate 61, an extrusion piece 62, and a linkage rod 63. The lower end of the pressure plate 61 is installed with the extrusion piece 62. The extrusion piece 62 is slidably arranged in the accommodating groove opened at the top of the upper fastener 1. The linkage rod 63 is slidably arranged inside the upper fastener 1. A spring five is connected between the linkage rod 63 and the upper fastener 1. The spring five plays a resetting role. The left and right ends of the linkage rod 63 are respectively extruded with the lifting groove 552 and the extrusion piece 62.
[0040] Reference Figure 3 As shown, the pressure plate 61 is made of polyurethane. The full name of polyurethane is polyurethane, which is a polymer material with excellent mechanical properties formed by the condensation reaction of polyols and polyisocyanates. The polyurethane material has extremely high hardness and certain elasticity.
[0041] In the actual tightening and installation process, the hexagonal nut 41 is continuously tightened on the bolt 3, and the flange pressing block 42 gradually contacts and squeezes the pressure plate 61, and the pressure plate 61 is squeezed and moved downward, and the extrusion piece 62 moves downward with the pressure plate 61, and the downward moving extrusion piece 62 squeezes the linkage rod 63, and the linkage rod 63 squeezes the lifting groove 552 to make the resistance block 551 rise. At the same time, the linkage rod 63 eccentrically squeezes the blocking plate 559 to unlock the guide pin 557. When the bottom surface of the pressure plate 61 contacts the bottom surface of the receiving groove, the bottom surface of the movable ring 431 also contacts the bottom surface of the receiving groove, and then the hexagonal nut 41 continues to be tightened, and the pressure exerted on the pressure plate 61 by the flange pressing block 42 gradually increases, thereby making the pressure The plate 61 is compressed and the flange pressing block 42 descends, but the movable ring 431 is blocked by the accommodating groove and remains in position. Therefore, the flange pressing block 42 descends relative to the movable ring 431, and the embedded layer 432 is exposed to the sight, thereby reminding the personnel to tighten in place. At the same time, the flange pressing block 42 moving downward makes the position of the clamping groove 434 correspond to the position of the clamping block 433. Under the action of spring 2, the clamping block 433 is inserted into the clamping groove 434, thereby locking the position between the movable ring 431 and the flange pressing block 42 (at this time, the flange pressing block 42 cannot descend relative to the movable ring 431, but the flange pressing block 42 can rise relative to the movable ring 431), and the flange pressing block 42 cannot continue to move downward, thereby ensuring that it is not over-tightened.
[0042] Reference Figure 5 As shown, the heat dissipation module 7 includes a perforated plate 71, which is slidably arranged in a hollow groove opened inside the clamping claw 51. A spring six is connected between the perforated plate 71 and the hollow groove. The spring six always pushes the perforated plate 71 toward the rotating shaft 52. Through holes are evenly opened on the perforated plate 71, and smooth holes corresponding to the positions of the through holes are opened on the side walls of the clamping claw 51. The through holes and the smooth holes are in a staggered state in the initial state, and a recessed groove 521 corresponding to the position of the perforated plate 71 is opened on the rotating shaft 52.
[0043] In the actual heat dissipation process, when the position between the sliding rod 53 and the switching groove 554 corresponds, the clamping claw 51 rotates outward to open so that the position between the hole plate 71 and the recessed groove 521 corresponds. Under the action of spring six, the hole plate 71 moves and is inserted into the recessed groove 521, so that the position between the through hole and the unblocked hole corresponds, so that the clamping claw 51 is in a breathable state, providing a channel for the side of the cable to dissipate heat.

[0045] Step 1: buckle the upper fastener 1 onto the cable to be connected, and the clamping module 5 simply clamps and fixes the cable;
