Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, and in particular to a multifunctional cable tray for outdoor testing. Background Technology

[0002] Cable trays can generally be classified into: ladder-type cable trays, trough-type cable trays, tray-type cable trays, combined cable trays, fire-resistant cable trays, and fiberglass cable trays, etc. They are mainly composed of straight sections, supports, bends, and other components of trays or ladders. They can be installed independently or laid on various building and pipe rack supports. Due to their simple structure, beautiful appearance, flexible configuration, and convenient maintenance, they are widely used.

[0003] Outdoor test cable trays often require repeated wiring during operation to meet the operational testing needs of multiple batches of equipment. The placement of equipment on site also varies, often requiring adjustments to cable direction and replacement of different angled connectors. Frequent replacements lead to low testing efficiency and high costs. In addition, most existing cable trays are enclosed, and the heat generated by the cables causes the internal temperature of the cable tray to rise, which is difficult to dissipate. If the cable tray temperature remains too high for an extended period, it can lead to cable aging or even high-temperature damage to the cables, posing a significant risk to personnel and equipment. Utility Model Content

[0004] The purpose of this invention is to provide a multifunctional cable tray for outdoor testing, which can adjust the angle and length of the reversing joints according to actual conditions, making installation convenient, improving testing efficiency, enhancing heat dissipation, and improving safety during the testing process.

[0035] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0036] Please refer to Figures 1-10 This utility model provides a multifunctional cable tray for outdoor testing, including a junction box 2, a thermometer 10 installed on the junction box 2, a flexible connector 3 connected to one side of the junction box 2, a plurality of splicable cable tray cover plates 4 connected to one end of the flexible connector 3, cable tray side plates 5 fixedly connected to both sides of the cable tray cover plates 4, cable support beams 18 connected to the bottom of the cable tray side plates 5 on both sides, a cable partition 16 installed in the middle of the cable tray cover plate 4, power cables 15 and communication control cables 17 respectively arranged on both sides of the cable partition 16, and a temperature sensor 14 is provided on each power cable 15 and communication control cable 17.

[0037] This application incorporates the advantages of ladder-type cable trays, combined cable trays, and cable junction boxes. Structurally, it adopts a composite cable tray form, which has advantages such as light weight, low cost, beautiful appearance, convenient installation, high load-bearing capacity, and good heat dissipation and ventilation.

[0038] The junction box 2 has a cover plate 1 installed on one side, and the cover plate 1 is equipped with a power indicator light 9 and an over-temperature indicator light 11.

[0039] By setting up a live indicator light 9 and an EPO emergency trip button, the operator can be visually alerted to the current live status of the cable, which improves safety. The EPO emergency trip button can cut off the power in case of an emergency on site, effectively solving a series of operational problems such as the need to change the equipment under test multiple times, frequent cable splicing, high operation difficulty, the need for multiple people to operate, and the risk of live operation when testing outdoor cable trays.

[0040] A side plate connecting plate 6 is connected between several cable tray side plates 5. A sealing plate 7 is installed at the end of the cable tray side plate 5. A tower-shaped rubber ring 8 is installed on the sealing plate 7. A trapezoidal cabinet of this device is installed on the wall where the cable exits. The cabinet is equipped with copper busbars arranged vertically inside to facilitate the connection of cables inside and outside the wall. The device can be disassembled in sections at the end of the test. It is simple and convenient to test multiple different connections.

[0041] Several heat dissipation holes 12 are provided on the side plate 5 of the cable tray, and several water passage holes 13 are provided at the bottom of the cable tray.

[0042] This design adopts a ladder-type semi-enclosed structure. Opposite heat dissipation holes 12 are opened on the side plate 5 of the cable tray to evenly distribute and increase the airflow of heat dissipation. The cables arranged in the cable tray are generally divided into power cables 15 and communication control cables 17. Partitions are added between different cables to isolate shielding interference between different cables, increase protection effect, and provide individual heat dissipation.

[0043] The installation of outdoor cable trays needs to take into account the water accumulation during rainy days. This application adopts the design of water passage holes 13 to meet the water passage requirements of normal rainfall. The holes are evenly distributed with opposite openings on the two side plates 5 of the cable tray. In the event of water accumulation, rainwater can be smoothly discharged from the water passage holes 13 at the bottom.

[0044] The cable trays in this application are installed outdoors for testing multiple batches of equipment. Additional protection is required for the cable outlets. A separate outlet sealing plate 7 is designed. The sealing plate 7 is equipped with an independent tower-shaped rubber ring 8 for the outlets of different cables. It can be cut according to the cross-section and quantity of the cables to provide protection.

[0045] The flexible connector 3 includes a flexible top cover 31 and a rigid side support 32. The flexible top cover 31 is fixedly connected to the rigid side support 32, and adjacent rigid side supports 32 are connected by hinges 33.

[0046] In this application, the flexible connector 3 serves as a reversing joint for the cable tray. By using flexible materials, the angle and length can be adjusted in real time according to the actual environment. It has better flexibility in on-site laying and installation than traditional rigid metal reversing joints, which can improve the connection accuracy between the reversing joint and the cable tray, thereby ensuring the performance of the reversing joint.

[0047] A curved heat-conducting plate 141 is installed at the bottom of the temperature sensor 14. The detection probe of the temperature sensor 14 is set inside the curved heat-conducting plate 141. Mounting plates 19 are fixedly connected to both sides of the cable partition 16. The bottom of the mounting plate 19 is fixedly connected to the cable support beam 18. A limit hole 191 is provided on the mounting plate 19. A limit rod 21 is slidably connected in the limit hole 191. A keyway 211 is provided on the limit rod 21. A movable block 20 is fixedly connected to the bottom of the limit rod 21. The temperature sensor 14 is fixedly installed in the movable block 20. The lower end of the movable block 20 and the curved heat-conducting plate 141 are respectively abutted against the power cable 15 and the communication control cable 17. A spring 212 is installed on the limit rod 21. The bottom of the spring 212 is fixedly installed on the mounting plate 19.

[0048] In the specific setup, the temperature sensor 14 is installed inside the movable block 20, which is located below the mounting plate 19. The spring 212 is located above the mounting plate 19. The arc-shaped heat-conducting plate 141 and the movable block 20 press against the cable under the elastic force of the spring 212. This can limit the cable and ensure the contact between the temperature sensor 14 detection probe and the cable surface, thereby ensuring the smooth operation of the cable temperature detection.

[0049] By installing temperature sensors 14 on each cable, the temperature of each cable and the ambient temperature inside the cable tray are monitored in real time and displayed in the thermometer 10. If the temperature exceeds the set temperature, the over-temperature indicator 11 will promptly alarm and provide feedback to the on-site testing personnel, thereby improving the safety of on-site testing.

[0050] In summary, the working principle of a multifunctional cable tray for outdoor testing according to this utility model embodiment is as follows:

[0051] The trapezoidal cabinet of this invention is installed on the wall where the cable exits. The cabinet is equipped with copper busbars arranged vertically inside to facilitate the connection of cables inside and outside the wall. The cable tray cover plate 4 and the cable tray side plate 5 are spliced ​​together and fixed at the splice by the side plate connecting plate 6. The movable block 20 is moved upward so that the cable is located below the movable block 20. When the movable block 20 is released, the movable block 20 and the arc-shaped heat-conducting plate 141 press against the cable under the elastic force of the spring 212 to fix the cable. The temperature sensor 14 detects the probe in contact with the cable surface to detect the cable temperature. The detection result is displayed in the thermometer 10. If the temperature exceeds the set temperature, the over-temperature indicator light 11 will promptly alarm and provide feedback to the on-site test personnel, improving the safety of on-site testing. The live indicator light 9 visually indicates to the operator the current live status of the cable, improving safety. The EPO emergency trip button can trip the power in case of an emergency on-site. After the test, the device can be disassembled in sections to facilitate multiple tests of different transfers.

[0052] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
