Abstract
Description
Technical Field
[0001] This utility model belongs to the field of overload protection circuit breaking technology, and specifically relates to an overload protection circuit breaking device for a photoelectric storage centrifuge. Background Technology
[0002] Against the backdrop of the global energy structure accelerating its transition to renewable energy, the photovoltaic-storage centrifuge, as the core equipment in the photovoltaic energy storage system, undertakes the key functions of energy conversion, storage and release. Its operational stability and safety play a decisive role in the efficiency and lifespan of the entire energy storage system. At present, the photovoltaic-storage centrifuge generally uses circuit breakers as overload protection devices. When the equipment experiences abnormal operating conditions such as overload or short circuit, the circuit breaker cuts off the circuit to prevent the equipment from being damaged due to excessive current.
[0003] In the current installation and connection process between photovoltaic storage centrifuges and circuit breakers, the connecting lines are often bent to adapt to the installation space, and the bent lines lack effective fixing measures. During subsequent equipment maintenance operations, the lines are easily pulled by external forces, which can lead to poor contact between the photovoltaic storage centrifuge lines and the circuit breaker. This not only increases the difficulty and cost of maintenance, but may also cause safety hazards due to line faults, further threatening the stable operation of the photovoltaic storage centrifuges.
[0004] There are currently no effective solutions to the problems in the relevant technologies. Utility Model Content
[0005] In view of the problems in the related technologies, this utility model proposes an overload protection circuit breaker for a photovoltaic centrifuge to overcome the above-mentioned technical problems existing in the existing related technologies.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0007] This utility model relates to an overload protection circuit breaker for a photovoltaic centrifuge, comprising a circuit breaker body. Multiple wiring slots are provided at both ends of the circuit breaker body. Supporting mechanisms are symmetrically arranged on the circuit breaker body and on both sides of each wiring slot. A moving mechanism is slidably installed between two symmetrical supporting mechanisms. The moving mechanism is fixed to the two supporting mechanisms by multiple fastening mechanisms. A limiting mechanism is symmetrically slidably installed within the moving mechanism. A rotary drive mechanism is installed at the far ends of the two limiting mechanisms. The two rotary drive mechanisms are threadedly installed to the moving mechanism.
[0008] Furthermore, both of the support mechanisms include support frames, one end of each support frame is fixedly installed on the circuit breaker body, a guide plate is fixedly installed on the top of the support frame, and a guide groove is formed in the guide plate.
[0009] Furthermore, the moving mechanism includes a sliding frame, with sliders symmetrically fixedly installed at both ends of the sliding frame, and the two sliders are slidably installed in the two guide grooves respectively.
[0010] Furthermore, threaded holes are symmetrically opened inside the slider, and sliding rods are symmetrically fixedly installed on the inner wall of the sliding frame.
[0011] Furthermore, the fastening mechanism includes a washer and a bolt, the bolt being threaded into the threaded hole.
[0012] Furthermore, the limiting mechanism includes an arc-shaped clamping plate, with sliding pieces fixedly installed at both ends of the arc-shaped clamping plate. The two sliding pieces are slidably installed with the two sliding rods respectively, and multiple rubber strips are arranged in a circumferential array on the inner ring of the arc-shaped clamping plate.
[0013] Furthermore, the rotary drive mechanism includes a lead screw, the end of which is rotatably mounted on the arc-shaped clamp.
[0014] Furthermore, the lead screw is threadedly installed with the sliding frame, and a handwheel is fixedly installed at the other end of the lead screw.
[0015] This utility model has the following beneficial effects:
[0016] This utility model requires construction personnel to rotate the two drive mechanisms corresponding to one side of the wiring slot in sequence. Since the two drive mechanisms are threadedly installed with the moving mechanism, when the two drive mechanisms rotate, they will simultaneously move towards both ends of the wire harness. Subsequently, the two moving mechanisms will drive the corresponding limiting mechanisms to move. Since the two limiting mechanisms are slidably installed with the moving mechanism, the moving mechanism will guide the sliding of the limiting mechanisms. Therefore, when the two drive mechanisms rotate, the two limiting mechanisms will move towards each other along the moving mechanism towards the wire harness. After the two limiting mechanisms move to both ends of the outer wall of the wire harness, they will limit and fix the outer walls of both ends of the wire harness, thereby preventing poor contact between the circuit of the photovoltaic storage centrifuge and the circuit breaker due to the wire harness being pulled by external force during subsequent equipment maintenance operations.
[0017] This utility model uses a screwdriver to tighten the fastening mechanism, thereby releasing the locking state between the moving mechanism and the support mechanism. Then, the construction worker pulls the moving mechanism by hand, causing it to slide along the guide structure of the two support mechanisms. During the pulling process, the construction worker can adjust the moving mechanism to a position that fits the fixed wire harness according to the actual situation of the wire harness.
[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.
[0029] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.
[0030] Please see Figures 1-6 As shown, this utility model is an overload protection circuit breaker for a photovoltaic centrifuge, including a circuit breaker body 1. Multiple wiring slots 2 are provided at both ends of the circuit breaker body 1. Supporting mechanisms 3 are symmetrically provided on the circuit breaker body 1 and on both sides of each wiring slot 2. A moving mechanism 4 is slidably installed between two symmetrical support mechanisms 3. The moving mechanism 4 and the two support mechanisms 3 can be fixed together by multiple fastening mechanisms 5. A limiting mechanism 6 is symmetrically slidably installed inside the moving mechanism 4. A rotary drive mechanism 7 is installed at the far ends of the two limiting mechanisms 6. The two rotary drive mechanisms 7 are threadedly installed on the moving mechanism 4.
[0031] First, strip the outer sheath of the wire harness from the optical storage centrifuge and place it through the moving mechanism 4 into the corresponding wiring slot 2 on the circuit breaker body 1. Then, use a screwdriver to loosen the fastening mechanism 5, releasing the locking state between the moving mechanism 4 and the support mechanism 3. Next, the installer manually pulls the moving mechanism 4, allowing it to slide along the guide structure of the two support mechanisms 3. During this pulling process, the installer can adjust the moving mechanism 4 to a suitable position for fixing the wire harness according to its actual condition. After adjustment, use a screwdriver to loosen the fastening mechanism 5 in the opposite direction, re-fixing the moving mechanism 4 onto the support mechanism 3 through the multiple fastening mechanisms 5. Then, to fix the wire harness, the installer needs to rotate the two drive mechanisms 7 corresponding to one side of the wiring slot 2 in sequence. The two drive mechanisms 7 and the moving mechanism 4 are threadedly installed. When the two drive mechanisms 7 rotate, they will move towards each other at both ends of the wire harness. Then, the two moving mechanisms 4 will drive the corresponding limiting mechanisms 6 to move. Since the two limiting mechanisms 6 and the moving mechanism 4 are slidably installed, the moving mechanism 4 will guide the sliding of the limiting mechanisms 6. So when the two drive mechanisms 7 rotate, the two limiting mechanisms 6 will move towards each other along the moving mechanism 4 towards the wire harness. After the two limiting mechanisms 6 move to both ends of the outer wall of the wire harness, they will limit and fix the outer walls of both ends of the wire harness. This prevents poor contact between the circuit of the optical storage centrifuge and the circuit breaker from being pulled by external force during subsequent equipment maintenance operations.
[0032] In one embodiment, for the above-mentioned support mechanism 3, both support mechanisms 3 include support frames 301, one end of each support frame 301 is fixedly installed on the circuit breaker body 1, and a guide plate 302 is fixedly installed on the top of the support frame 301, and a guide groove 303 is provided in the guide plate 302.
[0033] The moving mechanism 4 includes a sliding frame 401, with sliders 402 symmetrically fixedly installed at both ends of the sliding frame 401. The two sliders 402 are slidably installed in the two guide grooves 303 respectively.
[0034] The slider 402 has symmetrically opened threaded holes 403, and the inner wall of the sliding frame 401 has symmetrically fixed sliding rods 404.
[0035] The fastening mechanism 5 includes a washer 501 and a bolt 502, the bolt 502 being threaded into the threaded hole 403.
[0036] The operator first uses a screwdriver to turn the bolt 502, gradually moving it out of the threaded hole 403 of the slider 402. The bolt 502 is no longer pressing against the top of the washer 501, and the friction between the washer 501 and the guide plate 302 disappears. The slider 402 is then released from its locked state within the guide groove 303. The operator then manually applies force to the sliding frame 401, causing the sliders 402 at both ends to slide linearly along the guide groove 303, thus moving the entire moving mechanism 4 closer to or away from the wiring slot 2. Once the entire moving mechanism 4 reaches the appropriate fixing position for the wire harness, the operator reverses the rotation of the bolt 502, gradually pushing it deeper into the threaded hole 403. As the bolt 502 tightens, the washer 501 is compressed and pressed tightly against the top of the guide plate 302. Using friction and the threaded action of the bolt 502, the slider 402 is fixed in the designated position within the guide groove 303. The operator can then perform a limiting operation on the wire harness.
[0037] In one embodiment, the limiting mechanism 6 includes an arc-shaped clamping plate 601, with sliding pieces 602 fixedly installed at both ends of the arc-shaped clamping plate 601. The two sliding pieces 602 are slidably installed with the two sliding rods 404 respectively, and a plurality of rubber strips 603 are arranged in a circumferential array on the inner ring of the arc-shaped clamping plate 601.
[0038] The rotary drive mechanism 7 includes a lead screw 701, the end of which is rotatably mounted on the arc-shaped clamp 601.
[0039] The lead screw 701 is threadedly installed with the sliding frame 401, and a handwheel 702 is fixedly installed at the other end of the lead screw 701.
[0040] Based on the above working principle, after the entire moving mechanism 4 moves to the position for fixing the wire harness, the wire harness fixing operation begins. The construction worker manually rotates the two corresponding handwheels 702 simultaneously. Subsequently, the two handwheels 702 will drive the screws 701 fixedly installed on them to rotate. Since both screws 701 are threaded onto the sliding frame 401, the rotation of the two screws 701 will move along their own axes. Then, the two screws 701 will move towards the wire harness. Immediately afterwards, the two screws 701 will drive the arc-shaped clamp 601 rotatably installed on them to move. The arc-shaped clamp 601 has sliding pieces 602 fixed at both ends, and the two sliding pieces 602 are slidably installed with the two sliding rods 404. During movement, two sliding rods 404 guide the wire harness, allowing the arc-shaped clamp 601 to slide along the direction of the two sliding rods 404. Subsequently, the two arc-shaped clamps 601 move to both ends of the wire harness and then limit and fix both ends of the wire harness through the two arc-shaped clamps 601 to prevent poor contact between the circuit and the circuit breaker of the photovoltaic centrifuge from being pulled by external force during subsequent equipment maintenance operations. During the process of fixing the wire harness with the two arc-shaped clamps 601, multiple rubber strips 603 on the inner ring of each clamp will come into contact with the wire harness. The rubber strips 603 are made of rubber and are bent at the outer wall of the wire harness by the pressure of the arc-shaped clamps 601, thereby increasing the friction between the arc-shaped clamps 601 and the wire harness.
