Description

Technical Field

[0001] This utility model relates to the field of ship electrical wiring cable trays, specifically a ship electrical wiring cable tray. Background Technology

[0002] Cable trays are auxiliary equipment for standardizing cable laying and are widely used in building and engineering equipment, as well as in ships that integrate various engineering facilities.

[0003] In the prior art, such as in CN219227156U, a marine electrical wiring cable tray is disclosed. It includes a main cable tray and a cover plate. The main cable tray includes a base plate. One side of the base plate is fixedly connected to a first side wall, and the other side is fixedly connected to a second side wall. A first inward flange is fixedly connected to the top edge of the first side wall, and a second inward flange is fixedly connected to the top edge of the second side wall. The first and second inward flanges are provided with equally spaced opening and closing recesses on one side of the base plate. This invention utilizes the inward flange of the main cable tray in conjunction with the outward flange of the cover plate. The opening and closing recesses of the inward flange and the protrusions of the outward flange interlock, and the main cable tray and cover plate are further shifted and misaligned to allow the opening and closing recesses and protrusions to engage, thus achieving connection and locking between the main cable tray and the cover plate. This allows for quick connection and disassembly without screws, facilitating ship construction and maintenance. Furthermore, two identical slots can be interlocked, expanding the capacity of the cable tray.

[0004] Although the aforementioned patent achieves the effect of quick assembly and disassembly without screws by using the inner flange of the main cable tray and the outer flange of the cover plate, which is convenient for maintenance, the lack of a cable bundle structure inside the cable tray means that the wires are placed and tangled randomly, which will greatly increase the complexity of maintenance of individual circuits in the future. At the same time, it is impossible to monitor the condition inside the cable tray, and the working environment of the wires will affect the safety of the wires. Therefore, a marine electrical wiring cable tray is proposed to address the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, such as the lack of cable management structures inside cable trays leading to haphazard placement and tangling of wires, which significantly increases the complexity of maintaining individual circuits later on; and the inability to monitor the internal conditions of the cable trays, which can affect the safety of the wiring due to the working environment, this utility model proposes a marine electrical wiring cable tray.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The ship electrical circuit cable tray of this utility model includes a cable tray and a cover plate. The side of the cable tray is provided with grooves symmetrically arranged. The inner side wall of the cover plate is provided with a locking block that engages with the groove. A wire harness assembly is fixed on the surface of the cable tray. A connecting structure is fixedly connected to the bottom surface of the cable tray. A threaded hole is provided on the top surface of the cover plate and a monitoring assembly is connected thereto.

[0007] The wire harness assembly includes a frame and elastic plates symmetrically disposed on the inner wall of the frame. The end of the elastic plate has a rotating groove and is rotatably connected to a roller.

[0008] The monitoring component includes a device block threaded into a threaded hole. The device block has an internal cavity and a built-in wireless module. The bottom surface of the device block is equipped with a vibration sensor, a temperature sensor, and a humidity sensor.

[0009] Preferably, the grooves on the side of the cable tray are equidistantly distributed along the axial direction, and the locking block of the cover plate has a trapezoidal cross-section and is interference-fitted with the groove to form a self-locking mechanism.

[0010] Preferably, the elastic plate is fixedly connected to the inner side wall of the frame and is fitted to the inner side wall, the distance between the rollers of the two elastic plates is less than the outer diameter of the cable, and the outer surface of the rollers is covered with an elastic rubber layer.

[0011] Preferably, the vibration sensor is a piezoelectric ceramic sensor, the temperature sensor is a patch thermocouple, and the humidity sensor is a capacitive humidity probe, and all three are exposed inside the cable tray through through holes on the bottom surface of the equipment block.

[0012] Preferably, the outer wall of the device block is provided with an external thread that matches the threaded hole, the top of the cavity is provided with a waterproof terminal for electrical connection with the wireless module, and a sealing ring is provided between the bottom surface of the device block and the top surface of the cover plate.

[0013] Preferably, the wireless module includes a LoRa communication unit, the signal output terminals of the vibration sensor, temperature sensor, and humidity sensor are connected to the wireless module, and the top of the device block is provided with a signal enhancement metal sheet integrated with the antenna of the wireless module.

[0014] The advantages of this utility model are:

[0015] 1. This utility model uses an elastic plate of the wire harness assembly fixed to the inner wall of the frame and a roller with an elastic rubber layer at the end. The deformation of the elastic plate makes the roller spacing smaller than the outer diameter of the cable. This structure design achieves the function of clamping the cable and reducing friction damage, solves the problem of wire entanglement, and improves the convenience of later maintenance of individual lines.

[0016] 2. This utility model features a structure in which the monitoring component's equipment block is fixed to the top surface of the cover plate through threaded holes, and the vibration sensor, temperature sensor, and humidity sensor on its bottom surface are exposed inside the cable tray through through holes.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] Please see Figures 1-4 As shown, a ship electrical wiring cable tray includes a cable tray 1 and a cover plate 2. The side of the cable tray 1 is provided with grooves symmetrically arranged on the axis. The inner side wall of the cover plate 2 is provided with a locking block that engages with the groove. A wire harness assembly 3 is fixed on the surface of the cable tray 1. A connecting structure is fixedly connected to the bottom surface of the cable tray 1. The top surface of the cover plate 2 is provided with a threaded hole and connected to a monitoring assembly 4. The wire harness assembly 3 includes a frame 31 and elastic plates 32 symmetrically arranged on the inner wall of the frame 31. The end of the elastic plate 32 is provided with a rotating groove and rotatably connected to a roller 33.

[0025] During operation, the distance between the rollers 33 of the two elastic plates 32 is less than the outer diameter of the cable, and the outer surface of the rollers 33 is covered with an elastic rubber layer. When installing the cable, the cable is pressed between the two rollers 33. The elastic deformation of the elastic plates 32 causes the rollers 33 to expand outward. The cable slides between the two elastic plates 32 through the rotation of the rollers 33. After the elastic plates 32 rebound, the rollers 33 clamp the cable to prevent the cable from shifting and reduce pulling friction.

[0026] Furthermore, the monitoring component 4 includes a device block 41 threadedly connected to a threaded hole. The device block 41 has an internal cavity and a built-in wireless module 42. The bottom surface of the device block 41 is provided with a vibration sensor 43, a temperature sensor 44, and a humidity sensor 45.

[0027] During operation, a through hole is opened on the bottom surface of the device block 41 to install a vibration sensor 43, a patch temperature sensor 44, and a capacitive humidity sensor 45. The probes of the three sensors are exposed inside the cable tray 1 through the through hole to directly contact the cable environment. The waterproof terminal block on the top of the device block 41 is electrically connected to the wireless module 42 and connected to an external power supply. The signal output terminals of the vibration sensor 43, temperature sensor 44, and humidity sensor 45 are connected to the wireless module 42 through wires. A sealing ring is provided between the bottom surface of the device block 41 and the top surface of the cover plate 2 to prevent moisture intrusion. A signal enhancement metal sheet is embedded in the top of the device block 41 and integrated with the antenna of the wireless module 42 to improve the stability of data transmission.

[0028] Furthermore, the grooves on the side of the cable tray 1 are equidistantly distributed along the axial direction, and the cross-section of the locking block of the cover plate 2 is trapezoidal and is interference-fitted with the groove to form a self-locking mechanism.

[0029] During operation, pressing the cover plate 2 during installation causes the locking block to deform due to the pressure of the groove sidewall. After the locking block is fully embedded in the groove, it cannot be pulled out in reverse due to the trapezoidal structure, thus achieving tool-free quick installation and vibration-resistant loosening. It is especially suitable for high-frequency vibration environments on ships, improving the connection stability between the cable tray 1 and the cover plate 2.

[0030] Furthermore, the outer wall of the device block 41 is provided with an external thread that matches the threaded hole, the top of the cavity is provided with a waterproof terminal that is electrically connected to the wireless module 42, and a sealing ring is provided between the bottom surface of the device block 41 and the top surface of the cover plate 2.

[0031] During operation, the device block 41 is rotated to make its threads fasten to the top surface of the cover plate 2. A sealing ring is provided between the bottom surface of the device block 41 and the top surface of the cover plate 2 to prevent moisture from seeping in. The waterproof terminal on the top of the cavity is electrically connected to the wireless module 42 and provides a waterproof interface for the external power line. This design ensures that the monitoring component 4 is sealed and waterproof for a long time in the humid environment of the ship, while facilitating disassembly, maintenance or replacement of the sensor module, taking into account both reliability and modular expansion requirements.

[0032] Furthermore, the wireless module 42 includes a LoRa communication unit, and the signal output terminals of the vibration sensor 43, temperature sensor 44, and humidity sensor 45 are connected to the wireless module 42. The top of the device block 41 is provided with a signal enhancement metal sheet integrated with the antenna of the wireless module 42.

[0033] During operation, a signal-enhancing metal sheet is embedded on the top of the device block 41 and integrated with the antenna of the wireless module 42. Utilizing the low-power wide-area communication characteristics of LoRa, the vibration, temperature and humidity data inside the cable tray 1 are remotely transmitted to the monitoring terminal. The signal-enhancing metal sheet expands the wireless coverage range, solves the signal shielding problem in the metal compartments of ships, and realizes real-time monitoring of cable status and fault early warning.

[0034] Working principle: The axially equidistant grooves on the side of the cable tray 1 are interference-fitted with the trapezoidal locking blocks on the inner side of the cover plate 2. During installation, pressing the cover plate 2 causes the locking blocks to be squeezed and deformed by the sidewalls of the grooves, embedding and locking themselves to form a vibration-resistant closed cavity. The cable harness assembly 3 on the surface of the cable tray 1 clamps the cable through the elastic plates 32 symmetrically fixed inside the frame 31. When the cable is pressed into the space between the two rollers 33, the elastic plates 32 expand outward, and the rollers 33 rotate to reduce frictional resistance. After the elastic plates 32 rebound, the rollers 33 covered with elastic rubber clamp the cable to prevent displacement. The monitoring assembly 4 on the top of the cover plate 2 is fixed to the device block 41 through a threaded connection. The vibration sensor 43, temperature sensor 44, and humidity sensor 45 at the bottom of the device block 41 directly monitor the vibration, temperature, and humidity data of the cables inside the cable tray 1 through through holes. The data is transmitted to the monitoring terminal by the LoRa wireless module 42 inside the device block 41 through the top signal enhancement metal plate. The sealing ring and waterproof terminals between the device block 41 and the cover plate 2 prevent water vapor intrusion and ensure the long-term stability of the sensors in the humid environment of the ship. The overall solution enables rapid cable installation, real-time environmental monitoring, and fault early warning, thereby improving the safety and maintenance efficiency of the ship's electrical system.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, or similar improvements made within the theoretical and principle content of the present utility model should be included within the protection scope of the present utility model.
