Description

Technical Field

[0001] This utility model belongs to the field of hydropower construction technology, and in particular relates to a hydropower construction cable tray for underground parking lots. Background Technology

[0002] Cable trays, also known as wiring ducts or distribution ducts, are electrical tools widely used inside buildings, especially in complex environments such as underground parking lots. Their main function is to neatly organize and fix power lines, data cables, and other wires to walls or ceilings, ensuring neatness, safety, and ease of maintenance. Cable trays can be categorized by material into plastic cable trays (such as environmentally friendly PVC cable trays and halogen-free PPO cable trays) and metal cable trays (such as steel-aluminum cable trays and galvanized cable trays). Different materials offer different performance characteristics and are suitable for different scenarios. In the electrical and plumbing construction of underground parking lots, the selection and installation of cable trays are crucial, requiring them to meet the requirements of wiring installation while ensuring good electrical performance and safety even in humid and dimly lit environments.

[0003] Although existing cable trays play an important role in water and electricity construction, some problems still exist. In particular, because the inside of the cable tray is a single space, the wires are often all mixed together during routing, making them difficult to distinguish. This chaotic routing not only increases the difficulty of construction but also brings great inconvenience to later line maintenance and inspection. In addition, the piled-up wires in the cable tray are prone to tangling and are not independent of each other. This not only affects the heat dissipation performance of the line but also poses serious safety hazards. Once a fault occurs in one wire, such as a short circuit or overload, it may quickly affect other wires, triggering a chain reaction and causing serious consequences such as fires.

[0004] Therefore, we propose a method for constructing water and electricity cable trenches in underground parking lots to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that the existing cable trays are a whole space inside, and the wires are often all mixed together when running, which is not convenient for distinguishing and maintenance, and also poses a safety hazard. Therefore, a cable tray for water and electricity construction in underground parking lots is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A cable tray for water and electricity construction in an underground parking lot includes a tray body, a sealing plate for enclosing the tray body, and a positioning component for positioning the electrical wires. The positioning component includes:

[0008] Multiple positioning plates have multiple equally spaced wire holes. The multiple positioning plates are parallel to the cross-section of the tank and are disposed in the tank. The first positioning plate is fixedly connected to the tank, and the remaining positioning plates are slidably connected to the tank.

[0009] The take-up and release structure is set between two adjacent positioning plates to limit the distance between the two adjacent positioning plates, so that all the positioning plates are evenly distributed in the groove.

[0010] The wire end fixing structure, located on the positioning plate at the end, is used to fix and pull the wire.

[0011] Preferably, the edges of the threading hole are rounded.

[0012] Preferably, the sidewall of the trough is provided with a guide slot along the length of the trough, and the sidewall of the positioning plate is provided with a slide rod that matches the guide slot.

[0013] Preferably, the winding and unwinding structure includes a mounting box disposed on a positioning plate, a fixing rod coaxially mounted inside the mounting box, a winding wheel rotatably disposed inside the mounting box, a spring-loaded spring disposed between the winding wheel and the fixing rod, and a pull wire wound on the winding wheel, the movable end of the pull wire being connected to an adjacent positioning plate.

[0014] Preferably, the wire end fixing structure includes a first push rod and a second push rod slidably disposed on the positioning plate. Each of the first and second push rods is provided with an arc-shaped clamping plate corresponding to the wire through hole. The arc-shaped clamping plates on the first and second push rods are arranged in opposite directions and connected to a spring. A pushing mechanism is provided between the groove and the first and second push rods, so that when the positioning plate at the last position is in the initial position and the extreme position, the adjacent arc-shaped clamping plates are in a separated state. When the positioning plate at the last position pulls the wire to move, the adjacent arc-shaped clamping plates clamp the wire.

[0015] Preferably, a limiting post is installed on the first push rod, and a limiting groove is formed on the second push rod, wherein the limiting post extends into the limiting groove and is slidably connected to the limiting groove.

[0016] Preferably, the pushing mechanism includes a protrusion disposed on the inner wall of the groove, the length of the protrusion being consistent with the movement range of the positioning plate located at the end, an inclined portion being provided at the initial end of the protrusion, and a vertical portion being provided at the end of the protrusion.

[0017] Preferably, both the first push rod and the second push rod are provided with guide wheels at their ends, and the guide wheels abut against the surface of the convex strip.

[0018] In summary, the technical effects and advantages of this utility model are as follows: the wiring trough for water and electricity construction in the underground parking lot, with the wire-passing holes on each positioning plate, allows each wire to pass through different holes independently, avoiding direct contact and tangling between wires, greatly reducing the risk of fire caused by wire short circuits or overloads. At the same time, it also makes it easier for construction workers to quickly identify and distinguish different wires during the wiring process, improving construction efficiency and accuracy.

[0019] During wiring, positioning plates are stacked at the inlet end of the trough, making it convenient for construction workers to thread the wires one by one into the corresponding wiring holes as needed. Pulling the outermost positioning plate, combined with the wire end fixing structure, allows the wires to be easily pulled through the entire trough without tedious manual adjustments. After wiring is completed, the wire end fixing structure automatically loosens, simplifying the operation process and making subsequent wiring work smoother, greatly improving construction efficiency. In addition, the independently separated wires are more convenient to maintain, allowing for quick location and resolution of problematic wires, reducing maintenance time and costs.

[0020] With the help of the cable feeding and unloading structure, each positioning plate can be evenly distributed in the groove, providing uniform support for the wires. This effectively prevents the wires from becoming excessively concentrated or drooping due to gravity or external forces, ensuring the neatness and stability of the line. It not only improves the aesthetics but also avoids safety hazards such as insulation damage caused by excessive compression of the wires. Attached Figure Description

[0028] Reference Figure 1-6A cable tray for water and electricity construction in an underground parking lot includes a tray body 1, a sealing plate 2 for enclosing the tray body 1, and a positioning component 3 for positioning the cable. The tray body 1 is a U-shaped structure with an open top. The sealing plate 2 is used to enclose the upper part of the tray body 1 to prevent debris from falling into the tray body 1.

[0029] The positioning component 3 includes multiple positioning plates 31, a wire feeding and take-up structure 32, and a wire end fixing structure 33.

[0030] Multiple positioning plates 31 have multiple equally spaced wire-passing holes 311. When wires are threaded, they are passed through different wire-passing holes 311. With the support of multiple wire-passing holes 311 on the positioning plates 31, different wires are separated, avoiding wire tangling and facilitating wire identification. At the same time, the gap between wires is increased, improving heat dissipation and reducing safety hazards such as overheating and burning caused by wire accumulation. Multiple positioning plates 31 are parallel to the cross-section of the groove 1 and are set in the groove 1. The first positioning plate 31 is fixedly connected to the groove 1, and the remaining positioning plates 31 are slidably connected to the groove 1. When threading, the movable positioning plates 31 all move towards the fixed positioning plate 31 to facilitate threading. When the wire passes through the wire groove, all the movable positioning plates 31 are equally spaced, which helps to provide uniform support for the wire and effectively prevents the wire from being excessively concentrated or drooping due to gravity or external force. This ensures the neatness and stability of the line, not only improving the aesthetics but also avoiding safety hazards such as insulation damage caused by excessive wire compression.

[0031] Reference Figure 5 The edge of the wire hole 311 is rounded to reduce the wear of the wire insulation sheath during the wire pulling process.

[0032] Reference Figure 1-3 The side wall of the tank 1 is provided with a guide slot 11 along the length of the tank 1, and the side wall of the positioning plate 31 is provided with a slide rod 312 that is adapted to the guide slot 11. Through the cooperation of the slide rod 312 and the guide slot 11, the positioning plate 31 is ensured to slide stably in the tank 1.

[0033] The take-up and untake-down structure 32 is set between two adjacent positioning plates 31 to limit the distance between the two adjacent positioning plates 31, so that all positioning plates 31 are evenly distributed in the tank 1.

[0034] Reference Figure 2-4The cable winding and unwinding structure 32 includes a mounting box 321 mounted on a positioning plate 31. A fixing rod is coaxially mounted inside the mounting box 321. A winding wheel 322 is also rotatably mounted inside the mounting box 321. A spring 323 is positioned between the winding wheel 322 and the fixing rod. Initially, the spring 323 is relaxed. When the winding wheel 322 rotates, the spring 323 stores elastic potential energy. A pull wire 324 is wound on the winding wheel 322. The movable end of the pull wire 324 is connected to the adjacent positioning plate 31. The wire is pulled and moved by the movement of the positioning plate 31 that pulls the wire. At this time, the pull wire 324 is pulled out from the winding wheel 322 until the pull wire 324 is completely pulled out, and the positioning plates 31 at both ends of the pull wire 324 reach the farthest distance. The length of the pull wire 324 is the spacing between all the positioning plates 31 in the groove 1 when they are evenly distributed. When two positioning plates 31 reach the farthest distance, the pull wire 324 will continue to be pulled to extend until all the positioning plates 31 are evenly distributed in the groove 1. Through the spring 323, the pull wire 324 can be hidden and wound on the winding wheel 322 when the positioning plates 31 are stacked, so as to avoid the pull wire 324 from getting tangled with the wire.

[0035] The wire end fixing structure 33 is located on the last positioning plate 31 and is used to fix and pull the wire. In order to simplify the wiring operation, after the wire passes through all the wire holes 311 of the positioning plate 31, the wire is fixed by the wire end fixing structure 33, and the wire is pulled along the groove 1 by moving the positioning plate 31. After the wiring is completed, the wire is released to facilitate subsequent wiring construction.

[0036] Reference Figure 5-6The wire end fixing structure 33 includes a first push rod 331 and a second push rod 332 slidably mounted on the positioning plate 31. Both the first push rod 331 and the second push rod 332 are provided with arc-shaped clamping plates 333 corresponding to the wire through holes 311. The arc-shaped clamping plates 333 on the first push rod 331 and the second push rod 332 are arranged in opposite directions and connected to a spring 334. When the two opposing arc-shaped clamping plates 333 approach each other, they can clamp the wire in the wire through hole 311, thus fixing the wire. Since the wire end fixing structure 33 is only mounted on the last positioning plate 31, it does not affect the wire passing through the wire through holes 31 on the other positioning plates 31 during the traction process. The trough 1 slides within the trough. A pushing mechanism is provided between the trough 1 and the first push rod 331 and the second push rod 332. When the positioning plate 31 is in the initial position and the extreme position, the adjacent arc-shaped clamping plate 333 is in a separated state. During the traction electric movement of the positioning plate 31, the adjacent arc-shaped clamping plate 333 clamps the wire. It is not necessary to manually arrange the wire in the trough during the wire threading process. During the wire threading process, the positioning plate 31 with the wire end fixing structure 33 pulls the wire from the inlet end of the trough 1 to the outlet end to complete the wire threading directly. After the wire threading is completed, the wire end fixing structure 33 automatically releases the wire, which is convenient for the subsequent arrangement of the wire.

[0037] Reference Figure 5-6 A limiting post 335 is installed on the first push rod 331, and a limiting groove 336 is opened on the second push rod 332. The limiting post 335 extends into the limiting groove 336 and slides in connection with the limiting groove 336. Through the cooperation of the limiting post 335 and the limiting groove 336, the first push rod 331 and the second push rod 332 are kept in a stable state, which improves the stability when clamping the wire.

[0038] Reference Figure 3-6 The pushing mechanism includes a protruding rib 12 disposed on the inner wall of the groove 1. The length of the protruding rib 12 is consistent with the movement range of the last positioning plate 31. An inclined portion 13 is provided at the initial end of the protruding rib 12, and a vertical portion 14 is provided at the end end of the protruding rib 12. In the initial state, all the positioning plates 31 are stacked together. When the last positioning plate 31 is in the initial position, it does not contact the protruding rib 12. After the wire is inserted, the last positioning plate 31 is pulled. The first push rod 331 and the second push rod 332 respectively abut against the inclined portion 13 and move along the inclined portion 13, so that the first push rod 331... Rod 331 and the second push rod 332 approach each other, so that the arc-shaped clamping plate 333 clamps and fixes the wire end. At this time, when the last positioning plate 31 moves, it can pull the wire to be threaded. When it reaches the end position, the first push rod 331 and the second push rod 332 disengage from the protrusion 12. Under the action of the spring 334, the first push rod 331 and the second push rod 332 reset and are blocked by the vertical part 14, thus fixing the position of the last positioning plate 31. At the same time, the arc-shaped clamping plate 333 separates, and the wire can then be threaded.

[0039] Reference Figure 5-6 The ends of the first push rod 331 and the second push rod 332 are provided with guide wheels 337. The guide wheels 337 abut against the surface of the protrusion 12. The guide wheels 337 can effectively reduce the friction between the first push rod 331 and the second push rod 332 and the protrusion 12, which facilitates the traction movement of the last positioning plate 31.

[0040] Working principle:

[0041] Each end of the sealing plate 2 is provided with an independent inspection plate 21 for installation and maintenance. Opening the initial inspection plate 21 exposes all the positioning plates 31 piled up there. Insert the wires into the wire holes 311 in sequence. Pull the last positioning plate 31 to move. The first push rod 331 and the second push rod 332 abut against the inclined part 13 and move along the inclined part 13, so that the first push rod 331 and the second push rod 332 move closer to each other, so that the arc-shaped clamping plate 333 clamps and fixes the wire end. At this time, when the last positioning plate 31 moves, it can pull the wire for threading.

[0042] When pulling the wire, the last positioning plate 31 moves to pull the wire, pulling the pull wire 324 out of the winding wheel 322 until the pull wire 324 is completely pulled out. The positioning plates 31 at both ends of the pull wire 324 reach the farthest distance. When the two positioning plates 31 reach the farthest distance, they will continue to pull the subsequent pull wire 324 to extend until all positioning plates 31 are evenly distributed in the groove 1.

[0043] When the end position is reached, the first push rod 331 and the second push rod 332 disengage from the protrusion 12. Under the action of the spring 334, the first push rod 331 and the second push rod 332 are reset and blocked by the vertical part 14, thus fixing the position of the end positioning plate 31. At the same time, the arc-shaped clamp 333 separates, and the wire can then be threaded.
