[0001] The invention relates to the technical field of electrical equipment, and in particular to a relay protection device with a wire harness combing structure. Background Art

[0002] In the power system, relay protection equipment is a key line of defense to ensure a stable power supply. The wiring harnesses of traditional relay protection equipment are often disorganized, which causes many problems. Interference between lines is frequent, and signal transmission is easily affected, causing equipment to malfunction or refuse to operate.

[0017] Technical effects and advantages of the present invention: 1. The present invention provides a relay protection device with a wire harness combing structure. Since different types of relay protection devices have different wire harness installation positions, when wire harness combing work is carried out on different types of equipment, the auxiliary component can be driven by a rotating frame to deflect, thereby cleverly adapting to the different directions of the wire harness and effectively preventing the insulation layer of the wire harness from being accidentally scratched during the combing process.

[0018] 2. The present invention sets an adjustment mechanism, and when combing the wiring harness of the relay protection device, pushes the first sliding frame to allow the first sliding wheel on the first sliding frame to slide along the first sliding groove on the outer surface of the support frame. When the first sliding frame slides to the installation position of the relay protection device, the auxiliary component is used to clamp the wiring harness of the relay protection device, thereby realizing the combing of the wiring harness.

[0019] 3. The present invention sets a force-bearing frame. When the force-bearing frame moves toward one side of the rotating frame, the force-bearing frame squeezes the first sliding block through the connecting shaft. When the first sliding block slides into the first through hole, the first sliding frame is fixed under the restriction of the first sliding block, thereby preventing the first sliding frame from moving and causing the wiring harness of the relay protection device to fall off.

[0020] 4. The present invention sets an auxiliary component. As the second sliding frame drives the first clamping plate to gradually approach the wiring harness of the relay protection device, the second sliding frame pushes the second rotating rod with the help of the connecting action of the connecting rod. After the second rotating rod is subjected to force, it applies an extrusion force to the auxiliary rod. Under the action of this extrusion force, the auxiliary rod pushes the second clamping plate to flip in the direction of the wiring harness. When the second clamping plate flips, the wiring harness of the relay protection device is clamped and fixed, thereby enhancing the stability of the wiring harness during clamping, effectively avoiding the risk of the wiring harness falling off, and ensuring the stable operation of the equipment.

DETAILED DESCRIPTION

[0031] 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.

[0032] Embodiment 1 See also Figure 1-Figure 3 The present invention provides a technical solution: a relay protection device with a wire harness combing structure, comprising a power distribution cabinet 1, a cabinet door 2 is rotatably connected to the front of the power distribution cabinet 1 through a hinge, a support frame 3 is fixedly connected to the inner wall of the power distribution cabinet 1, a first through hole 4 is provided on the outer surface of the support frame 3, a first sliding groove 5 is provided on the outer surface of the support frame 3, and further comprising: The adjustment mechanism 6 includes a first sliding frame 601 slidably connected to the support frame 3, an outer wall of the first sliding frame 601 close to the first sliding groove 5 is rotatably connected to a first sliding wheel 602 through a rotating shaft, an outer surface of the first sliding wheel 602 is rollingly connected to the inner wall of the first sliding groove 5, a second sliding groove 603 is provided on the outer surface of the first sliding frame 601 away from the first sliding wheel 602, a rotating frame 604 is slidably connected to the inner wall of the first sliding frame 601, a force-bearing frame 606 is provided on the outer wall of the rotating frame 604 away from the first sliding frame 601, and a third through hole 61 is provided on the outer surface of the force-bearing frame 606 3. An auxiliary component 614 is provided on one side of the force-bearing frame 606 away from the rotating frame 604. The auxiliary component 614 is used to clamp the wiring harness of the relay protection device to achieve a combing effect. When the wiring harness of the relay protection device needs to be combed, the first sliding frame 601 is slid so that the first sliding frame 601 slides along the first sliding groove 5 opened on the outer surface of the support frame 3 through the first sliding wheel 602. When the first sliding frame 601 slides to the installation position of the relay protection device, the wiring harness of the relay protection device is clamped by the auxiliary component 614, thereby achieving a combing effect on the wiring harness of the relay protection device.

[0033] The outer wall of one side of the rotating frame 604 close to the second sliding groove 603 is rotatably connected to the second sliding wheel 605 through a rotating shaft. The end of the second sliding wheel 605 away from the rotating frame 604 is rotatably connected to the inner wall of the second sliding groove 603. The second sliding wheel 605 is used to improve the stability of the rotating frame 604 during rotation. Different types of relay protection devices have different wiring harness installation positions. When combing the wiring harnesses of different types of equipment, the auxiliary component 614 can be driven by the rotating frame 604 to deflect, so that effective combing can be achieved regardless of the inclination angle of the wiring harness of the relay protection device.

[0034] Embodiment 2 See also Figure 4-Figure 7 On the basis of the first embodiment, the present invention provides a technical solution: a second through hole 610 is opened on the outer surface of the rotating frame 604, and the inner wall of the force-bearing frame 606 is rotatably connected to the first rotating rod 611 through a rotating shaft. The end of the first rotating rod 611 away from the force-bearing frame 606 is rotatably connected to the second sliding block 612 through a rotating shaft. The second sliding block 612 is slidably connected to the inner wall of the second through hole 610. When the wiring harness of the relay protection device is installed on the device, the wiring harness will squeeze the force-bearing frame 606. After the force-bearing frame 606 is squeezed, the first rotating rod 611 pushes the second sliding block 612 to slide on the inner wall of the second through hole 610, thereby prompting the force-bearing frame 606 to move toward one side of the rotating frame 604, and then the first rotating rod 611 can improve the stability of the force-bearing frame 606 when it moves.

[0035] The outer wall of one side of the force-bearing frame 606 close to the rotating frame 604 is fixedly connected with a connecting shaft 607, and the end of the connecting shaft 607 away from the force-bearing frame 606 passes through the rotating frame 604 and is fixedly connected with a first sliding block 608, and the connecting shaft (607) is slidably connected to the rotating frame (604), and the outer wall of the first sliding block 608 close to the rotating frame 604 is fixedly connected with a first spring 609, and the end of the first spring 609 away from the first sliding block 608 is fixedly connected to the rotating frame 604, and the first spring 609 is used for resetting the first sliding block 608. When the force-bearing frame 606 moves toward the rotating frame 604, it will squeeze the first sliding block 608 through the connecting shaft 607 and push it into the first through hole 4. When the first sliding block 608 slides into the first through hole 4, the position of the first sliding frame 601 will be restricted by the first sliding block 608 and fixed, thereby preventing the first sliding frame 601 from accidentally moving, thereby preventing the wiring harness of the relay protection device from falling off due to the movement of the first sliding frame 601.

[0036] Embodiment 3 See also Figure 8-Figure 9 On the basis of the first and second embodiments, the present invention provides a technical solution: the auxiliary component 614 includes a second sliding frame 6141 slidably connected to the third through hole 613, the outer surface of the second sliding frame 6141 is fixedly connected to a connecting rod 6144, the outer wall of the second sliding frame 6141 close to the connecting rod 6144 is fixedly connected to a second spring 6145, one end of the second spring 6145 away from the second sliding frame 6141 is fixedly connected to the force frame 606, the second spring 6145 is used for resetting the second sliding frame 6141, the connecting rod 6144 is used to improve the stability of the second sliding frame 6141 when sliding, the inner wall of the second sliding frame 6141 is fixedly connected to an elastic component 6142, and the elastic component A first clamping plate 6143 is fixedly connected to the outer wall of one side of 6142 away from the second sliding frame 6141. When the wiring harness of the relay protection device passes through the auxiliary component 614 to be connected to the device, the second spring 6145 pushes the second sliding frame 6141 to move along the third through hole 613 toward the direction of the wiring harness of the relay protection device. The second sliding frame 6141 drives the first clamping plate 6143 to contact the outer surface of the wiring harness. The wiring harness squeezes the elastic component 6142 to cause it to deform, so that the first clamping plate 6143 can also produce a certain arc deformation, and then the contact area between the first clamping plate 6143 and the wiring harness is increased, thereby effectively avoiding the first clamping plate 6143 from causing damage to the wiring harness when fixing the wiring harness.

[0037] The outer wall of the force-bearing frame 606 is rotatably connected to an auxiliary rod 6146 via a rotating shaft, and the outer wall of the auxiliary rod 6146 at one end away from the force-bearing frame 606 is rotatably connected to a second clamping plate 6147 via a rotating shaft, and a third spring 6148 is fixedly connected to the outer wall of the second clamping plate 6147 on one side close to the auxiliary rod 6146, and the end of the third spring 6148 away from the second clamping plate 6147 is fixedly connected to the auxiliary rod 6146, and the inner wall of the auxiliary rod 6146 is rotatably connected to a second rotating rod 6149 via a rotating shaft, and the end of the second rotating rod 6149 away from the auxiliary rod 6146 is rotatably connected to the connecting rod 6144 Dynamic connection, when the second sliding frame 6141 drives the first clamping plate 6143 to move toward the wiring harness of the relay protection device, the second sliding frame 6141 will push the second rotating rod 6149 with the help of the connecting rod 6144, so that it squeezes the auxiliary rod 6146. After the auxiliary rod 6146 is squeezed, it pushes the second clamping plate 6147 to flip in the direction of the wiring harness of the relay protection device, thereby clamping and fixing the wiring harness of the relay protection device. When the second clamping plate 6147 clamps the wiring harness, the third spring 6148 plays a role, increasing the contact area between the second clamping plate 6147 and the wiring harness.
