Description

Technical Field

[0001] This utility model relates to the field of power plant construction equipment technology, specifically to a cable routing and branching fixing device for power plant construction. Background Technology

[0002] There are many types of power plants, such as coal-fired power plants, gas-fired power plants, and photovoltaic power plants.

[0003] A photovoltaic (PV) power station refers to a power generation system that utilizes solar energy, employs special materials such as crystalline silicon panels, inverters, and other electronic components, and is connected to the power grid to transmit electricity. PV power stations are among the green energy development projects most strongly encouraged by the state. They can be divided into independent power generation systems with batteries and grid-connected power generation systems without batteries. Solar power generation is divided into concentrated solar power (CSP) and photovoltaic (PV). Currently, commercially available solar power refers to solar photovoltaic (PV) power generation.

[0004] When building a photovoltaic power station, cables need to be laid. Most existing cables are fixed with cable ties during the routing process. Because the cables are long, workers need to bundle them again after a certain length, which is time-consuming and labor-intensive. Using cable ties for fixing and squeezing can cause the cables to cross and become messy, which wastes time and manpower in the later cleaning process and is inconvenient for workers to use. Utility Model Content

[0005] The purpose of this utility model is to provide a cable routing and branching fixing device for power plant construction, so as to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A cable routing and branching fixing device for power plant construction includes a cable rack, a slide rail fixedly connected to the upper surface of the cable rack, a receiving arc frame slidably connected to the inner wall of the slide rail via a slider, and a flip cover rotatably connected to the upper surface of the receiving arc frame via a hinge.

[0008] A positioning component is provided at one end of the receiving arc frame. The positioning component includes a positioning pull rod. A positioning hole is opened on the front side of the cable tray to mate with the positioning pull rod. The positioning pull rod is movably inserted into the inner wall of the positioning hole. An L-shaped positioning plate is movably sleeved on the outer wall of one end of the positioning pull rod. The L-shaped positioning plate is fixedly connected to one end of the receiving arc frame.

[0009] A further improvement of this utility model is that: a positioning collar is fixedly connected to the outer wall of the positioning rod near one end, and a return spring is movably connected to one side of the positioning collar, with the end of the return spring away from the positioning collar abutting against the L-shaped positioning plate.

[0010] A further improvement of this utility model is that a pull ring is fixedly connected to one end of the positioning rod.

[0011] A further improvement of this utility model is that: one end of the slide rail is detachably and fixedly connected to a slide rail sealing block by a sealing bolt.

[0012] A further improvement of this utility model is that: both the receiving arc frame and the flip cover are fixedly connected to one side with a docking ring, and the two sets of docking rings are detachably fixedly connected by docking bolts.

[0013] A further improvement of this utility model is that both ends of the cable tray are fixedly connected with mounting ears.

[0014] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0015] 1. This utility model provides a cable routing and fixing device for power plant construction. This device eliminates the need for cable ties to bundle cables segment by segment. Instead, it can fix a single group of cables simply by "placing the cable, closing the flip cover, and tightening the connecting bolts". The operation steps are simplified, and the position of the receiving arc frame can be adjusted by sliding. This avoids the tedious operation of "interval measurement and repeated tightening" in traditional cable tie bundling, significantly reducing manual operation time and the labor intensity of workers. It is especially suitable for long-distance and large-quantity cable routing scenarios, and the overall work efficiency is greatly improved.

[0016] 2. This utility model provides a cable routing and branching fixing device for power plant construction. The wrapping structure formed by the receiving arc frame and the flip cover can uniformly constrain the cable, avoiding the insulation layer damage caused by the "point compression" of the cable ties. At the same time, the arc-shaped inner wall of the receiving arc frame and the flip cover can fit against the outer surface of the cable, preventing the cable from shifting or crossing. This not only ensures the structural integrity and conductivity of the cable, but also reduces the safety hazards such as leakage and short circuit caused by cable misalignment and insulation layer damage, and extends the service life of the cable.

[0017] 3. This utility model provides a cable routing and branching fixing device for power plant construction. Through the cooperation of positioning components and slide rails, the lateral spacing of the receiving arc frames can be flexibly adjusted to adapt to the routing density requirements of different numbers and diameters of cables. At the same time, the number of receiving arc frames can be easily increased or decreased by disassembling the slide rail sealing block without re-drilling holes on the mounting surface, avoiding damage to the mounting surface structure, greatly improving the device's adaptability to changes in cable routing, and reducing the cost and time of equipment adjustment.

[0018] 4. This utility model provides a cable routing and branching fixing device for power plant construction. During later maintenance, only the connecting bolts need to be unscrewed to open the flip cover and directly take out or replace the cable without cutting any fixing components. When adjusting the position or number of the receiving arc frame, the operation steps are simple and no complicated tools are required. The adjustment can be completed quickly, which significantly reduces the labor and time costs of maintenance and improves the overall efficiency of power plant cable maintenance.

[0025] The present invention will be further described in detail below with reference to embodiments:

[0026] Example 1

[0027] like Figure 1-4 As shown, this utility model provides a cable routing and branching fixing device for power plant construction, including a cable rack 1, a slide rail 3 fixedly connected to the upper surface of the cable rack 1, a receiving arc frame 5 slidably connected to the inner wall of the slide rail 3 through a slider, and a flip cover 6 rotatably connected to the upper surface of the receiving arc frame 5 through a hinge.

[0028] A positioning component is provided at one end of the receiving arc frame 5. The positioning component includes a positioning rod 10. A positioning hole 4 is provided on the front side of the cable tray 1 to mate with the positioning rod 10. The positioning rod 10 is movably inserted into the inner wall of the positioning hole 4. An L-shaped positioning plate 9 is movably sleeved on the outer wall of one end of the positioning rod 10. The L-shaped positioning plate 9 is fixedly connected to one end of the receiving arc frame 5.

[0029] A positioning collar 11 is fixedly connected to the outer wall of the positioning rod 10 near one end. A return spring 12 is movably connected to one side of the positioning collar 11. The end of the return spring 12 away from the positioning collar 11 abuts against the L-shaped positioning plate 9.

[0030] A pull ring 13 is fixedly connected to one end of the positioning rod 10.

[0031] Example 2

[0032] like Figure 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, one end of the slide rail 3 is detachably and fixedly connected to the slide rail sealing block 14 by a sealing bolt 15.

[0033] Both the receiving arc frame 5 and the flip cover 6 are fixedly connected to one side with a docking ring 7, and the two sets of docking rings 7 are detachably fixedly connected by docking bolts 8.

[0034] Both ends of the cable tray 1 are fixedly connected to mounting ears 2.

[0035] The working principle of the cable routing and branching fixing device used in the construction of this power station will be explained in detail below.

[0036] like Figure 1-4 As shown, the overall installation of the device is as follows: The cable tray 1 is fixedly installed at the preset position required for the cable layout of the power station (such as the wall, the side wall of the equipment cabinet, the crossbeam of the steel structure support, etc.) by using the mounting ears 2 that are fixedly connected to both ends of the cable tray 1, and by using conventional fasteners such as expansion bolts and hexagonal bolts. This ensures that the cable tray 1 remains horizontal and structurally stable after installation, providing basic support for subsequent cable layout.

[0037] Cable placement and initial constraint: Rotate the flip cover 6 around the hinge connected to the upper surface of the receiving arc frame 5 to open the flip cover 6 and the receiving arc frame 5. Place the power cables, control cables or signal cables required for power station construction one by one into the arc-shaped groove of the receiving arc frame 5 to ensure that the cables are evenly distributed and do not overlap in the receiving arc frame 5, thus initially achieving the support and constraint of the cables.

[0038] Cable locking and fixing: Flip the flip cover 6 around the hinge in the opposite direction until the arc-shaped inner wall of the flip cover 6 and the arc-shaped inner wall of the receiving arc frame 5 together form a wrap-around space for the cable; at this time, the docking ring 7 fixed on one side of the receiving arc frame 5 is completely aligned with the docking ring 7 fixed on one side of the flip cover 6. Pass the docking bolt 8 through the two sets of aligned docking rings 7, and tighten the docking bolt 8 (with matching hexagonal nuts to ensure reliable thread connection) to make the receiving arc frame 5 and the flip cover 6 fit tightly together, and finally lock the cable in the closed space formed by the two, preventing the cable from coming out during subsequent adjustments or use.

[0039] Adjustment of the position of the receiving arc frame 5: When it is necessary to adjust the lateral spacing of the receiving arc frame 5 on the cable tray 1 according to the cable layout density, the operator holds and pulls the pull ring 13 fixed at one end of the positioning pull rod 10, causing the positioning pull rod 10 to slide axially along the guide hole (ensuring smooth sliding) at one end of the L-shaped positioning plate 9; during the sliding process of the positioning pull rod 10, the positioning collar 11 fixed on its outer wall simultaneously squeezes the return spring 12, so that the return spring 12 is in a compressed state until the end of the positioning pull rod 10 away from the pull ring 13 is completely pulled out from the positioning hole 4 on the front side of the cable tray 1. At this time, the receiving arc frame 5 is released from the positioning constraint of the slide rail 3 through the slider connected at the bottom. Then, push the receiving arc frame 5 so that it slides laterally along the inner wall of the slide rail 3 through the slider until it moves to the target position that matches the cable layout requirements.

[0040] Positioning and fixing of the receiving arc frame 5: After the receiving arc frame 5 moves to the preset target position, the pull ring 13 is released, and the return spring 12, which is in a compressed state, releases its elastic potential energy, pushing the positioning collar 11 to drive the positioning pull rod 10 to slide in the opposite axial direction along the guide hole of the L-shaped positioning plate 9, so that the end of the positioning pull rod 10 away from the pull ring 13 is re-inserted into the positioning hole 4 at the corresponding position of the cable tray 1. Through the insertion and cooperation of the positioning pull rod 10 and the positioning hole 4, the position of the receiving arc frame 5 on the slide rail 3 is locked, ensuring that the receiving arc frame 5 does not slide accidentally after adjustment.

[0041] Increase or decrease in the number of receiving arc frames 5: When the number of power station cables increases or decreases, requiring adjustment of the total number of receiving arc frames 5, use a screwdriver or other tools to unscrew the slide rail sealing block 14 fixed at one end of the slide rail 3 by the sealing bolt 15, so that the end of the slide rail 3 forms an open port; then, slide the extra receiving arc frames 5 into the slide rail 3 from the open end of the slide rail 3 through the bottom slider, or slide the excess receiving arc frames 5 out from the open end of the slide rail 3. After completing the quantity adjustment, reattach the slide rail sealing block 14 to the end of the slide rail 3 and tighten it with the sealing bolt 15 to prevent the receiving arc frames 5 from coming off the end of the slide rail 3, ensuring the integrity of the overall structure of the device.

[0042] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
