Description

Technical Field

[0001] This utility model relates to the field of transformer wiring technology, specifically to a wiring device for a photovoltaic box-type transformer. Background Technology

[0002] Photovoltaic box-type transformers play a crucial role in power conversion and transmission in photovoltaic power plants. As the scale of photovoltaic power plants continues to expand, the management and maintenance of the transformer's internal wiring becomes increasingly important. Traditional photovoltaic box-type transformer wiring devices primarily use fixed wiring structures inside the transformer casing, such as simple brackets or slots, to secure and organize the wires.

[0003] CN218525424U discloses a wiring device for a box-type transformer used in a photovoltaic power station. The transformer wiring mechanism includes a transformer housing, a busbar installed inside the transformer housing cavity, grooves symmetrically formed on the upper ends of both sides of the inner wall of the transformer housing, a fixing and holding assembly disposed within the grooves, and a wire harness assembly snapped between the two sets of fixing and holding assemblies. One end of the busbar is fixedly provided with a wire, and the end of the wire away from the busbar passes through the wire harness assembly. The wire is snapped into the wire harness assembly. This invention adds a fixing and holding assembly and a wire harness assembly inside the transformer housing cavity. After the busbar is installed in the transformer housing, each wire on the busbar passes through the corresponding wire harness assembly above. The wire harness assembly restricts the wires, preventing interference between different wires and avoiding tangling of wires when there are too many, which could lead to safety hazards. It also facilitates organization and maintenance. However, the existing technology still has drawbacks.

[0004] The existing wiring devices have fixed wire spacing, which cannot be flexibly adjusted according to the thickness and quantity of wires and actual wiring needs. This results in either excessive crowding between wires of different specifications and quantities, increasing the risk of short circuits, or excessive spacing between wires, wasting space and affecting the compact layout inside the transformer. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the above-mentioned defects and provide a wiring device for a photovoltaic box-type transformer.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a wiring device for a photovoltaic box-type transformer, comprising:

[0007] The support rod has a connecting groove at its lower end;

[0008] A support frame is slidably connected to the outside of a support rod. A connecting block is fixedly connected to the middle of the upper end of the support frame. A storage groove is provided at the upper end of the connecting block, and a sliding hole is provided at the lower end of the storage groove.

[0009] A sliding rod, which is slidably connected inside a sliding hole;

[0010] A locking assembly is disposed inside a connecting groove. The locking assembly includes a locking groove, a locking block, a spring, and a pull plate. The locking groove is opened at the upper end of the connecting groove. The locking block is inserted into the locking groove and is fixedly connected to the upper end of a slide rod. The spring is disposed at the lower end of the locking block and is disposed inside a storage groove. The spring is sleeved on the outside of the slide rod. The pull plate is fixedly connected to the lower end of the slide rod.

[0011] A support plate, which is fixedly connected to the upper end of the support frame;

[0012] A clamping assembly is disposed on the upper end of a support plate.

[0013] As an improvement, the clamping assembly includes:

[0014] A sliding groove is formed at the upper end of the support plate;

[0015] A slider, which is slidably connected to the upper end of a groove;

[0016] A lead screw, which is rotatably connected inside a slide groove, and a slider is threadedly connected to the outside of the lead screw;

[0017] A clamping plate is fixedly connected to one upper side of the support plate and the upper end of the slider.

[0018] An adjusting block is fixedly connected to one end of a lead screw.

[0019] As an improvement, the clamping plates are fixedly connected to a clamping pad on one side close to each other.

[0020] As an improvement, a fixing plate is fixedly connected to both sides of the support rod, and mounting holes are opened at the front and rear ends of one side of the fixing plate.

[0021] The advantages of this utility model compared with the prior art are as follows: 1. By setting a support frame and locking components, the position of the support plate can be flexibly adjusted according to the thickness and number of wires. Users can quickly adjust the spacing between wires according to actual needs, avoid mutual interference between wires, and make full use of the internal space of the transformer, thereby improving space utilization and effectively solving the problem of fixed wire spacing and inflexible adjustment in the prior art.

[0022] 2. The clamping assembly design ensures a more secure hold on the wires. Through the tight fit of the clamping plates and pads, and the precise adjustment of the lead screw and slider, the wires are firmly clamped, preventing them from loosening or falling off even during transformer operation and vibration. Furthermore, the adjustability of the clamping assembly makes fixing and loosening the wires more convenient, significantly improving the efficiency of wire installation and maintenance.

[0031] Example 1:

[0032] like Figures 1 to 5As shown, this embodiment proposes a wiring device for a photovoltaic box-type transformer, including: a support rod 1, a connecting groove 11, a support frame 2, a connecting block 21, a storage groove 22, a sliding hole 23, a sliding rod 3, a locking assembly 4, a support plate 5, and a clamping assembly 6. The lower end of the support rod 1 has a connecting groove 11. The support frame 2 is slidably connected to the outside of the support rod 1. The middle of the upper end of the support frame 2 is fixedly connected to the connecting block 21. The upper end of the connecting block 21 has a storage groove 22. The lower end of the storage groove 22 has a sliding hole 23. The sliding rod 3 is slidably connected inside the sliding hole 23. The locking assembly 4 is installed inside the connecting groove 11. The support plate 5 is fixedly connected to the upper end of the support frame 2. The clamping assembly 6 is installed on the upper end of the support plate 5. After the locking assembly 4 releases the fixation of the support frame 2 and the support plate 5, the support frame 2 and the support plate 5 are moved. After adjusting the position of multiple support plates 5, the position of the support frame 2 and the support plate 5 is fixed by the locking assembly 4. Then, the clamping assembly 6 clamps and fixes the cable.

[0033] The locking assembly 4 includes a locking groove 41, a locking block 42, a spring 43, and a pull plate 44. The locking groove 41 is located inside the upper end of the connecting groove 11. The locking block 42 is inserted into the locking groove 41 and is fixedly connected to the upper end of the slide rod 3. The spring 43 is installed at the lower end of the locking block 42 and inside the storage groove 22. The spring 43 is sleeved on the outside of the slide rod 3. The pull plate 44 is fixedly connected to the lower end of the slide rod 3. By pulling the slide rod 3 through the pull plate 44, the slide rod 3 causes the locking block 42 to disengage from the locking groove 41, releasing the lock on the support frame 2 and the support plate 5. After adjusting the position of the support frame 2 and the support plate 5, the pull plate 44 is opened, and the spring force of the spring 43 pushes the locking block 42 into the locking groove 41, thus stably locking the support frame 2 and the support plate 5.

[0034] The clamping assembly 6 includes: a slide groove 61, a slider 62, a lead screw 63, a clamping plate 64, and an adjusting block 65.

The clamping plate 64 is fixedly connected to one side of the upper end of the support plate 5 and the upper end of the slider 62. The adjusting block 65 is fixedly connected to one end of the lead screw 63. By rotating the adjusting block 65 with a tool, the adjusting block 65 drives the lead screw 63 to rotate. The lead screw 63 controls the slider 62 to slide inside the slide groove 61. The slider 62 drives a clamping plate 64 to move, thus stably clamping and fixing the cable.

[0035] The clamping plates 64 are fixedly connected to the clamping pads 7 on one side of each other, and the clamping pads 7 provide cushioning when clamping the cable.

[0036] The support rod 1 is fixedly connected to the fixing plate 8 on both sides. The fixing plate 8 has mounting holes 9 at both the front and rear ends on one side. The support rod 1 is installed and fixed through the fixing plate 8 and the mounting holes 9.

[0037] In use, the sliding rod 3 is pulled by the pull plate 44, and the sliding rod 3 drives the locking block 42 to disengage from the locking groove 41, releasing the lock on the support frame 2 and the support plate 5. After adjusting the position of the support frame 2 and the support plate 5, the pull plate 44 is opened, and the locking block 42 is pushed into the locking groove 41 by the elastic force of the spring 43, so that the support frame 2 and the support plate 5 are stably locked. The adjusting block 65 is rotated by the tool, and the adjusting block 65 drives the lead screw 63 to rotate. The lead screw 63 controls the slider 62 to slide inside the slide groove 61. The slider 62 drives a clamping plate 64 to move, so as to stably clamp and fix the cable.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
