Description

Technical Field

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

[0002] Cable trays play a vital role in electrical engineering. As key equipment for cable laying and support, their structural design and functional configuration have a decisive impact on the safety and stability of the overall electrical system. Especially in building environments with concentrated cable laying and complex spatial layouts, cable trays not only bear the basic function of supporting cables but also need to possess good ventilation and heat dissipation performance as well as a certain level of protection. Cable trays typically consist of a tray body and a cover plate, and are widely used in various scenarios such as industrial plants, commercial buildings, and underground utility tunnels, making them an indispensable and important component of modern building electrical systems.

[0003] However, in practical applications, especially in locations with high fire safety requirements, existing cable trays have gradually revealed a series of obvious limitations and technical problems. Utility model patent CN222366023U discloses a cable tray including a main body and a cover plate. The main body has an internal adjustment mechanism that limits the cable position using upper and lower limit seats, positioning it between them. Simultaneously, the weight of a counterweight presses a pressure plate downwards, effectively fixing the cable. A limiting bracket engages with the top of the cover plate, ensuring the cover plate is tightly against the main body. This eliminates the need for multiple cable limiting points, improving the efficiency of cable limiting.

[0004] While this structure offers advantages in improving cable containment efficiency, existing cable trays generally lack effective fire protection. In the event of a fire, ordinary cable trays cannot effectively prevent the spread of flames along the tray or provide sufficient fire resistance for the internal cables, easily leading to the fire spreading and even secondary disasters. Furthermore, the dense arrangement of cables inside cable trays causes rapid heat accumulation once a fire starts; traditional trays lack heat insulation and flame-retardant capabilities, further exacerbating safety hazards. Therefore, addressing the numerous shortcomings of existing technologies, we urgently need a fire-resistant cable tray. Utility Model Content

[0005] The purpose of this invention is to provide a fire-resistant cable tray, solving the problem that existing cable trays generally lack effective fire protection. In the event of a fire, ordinary cable trays cannot effectively prevent the spread of flames along the tray, nor can they provide sufficient fire resistance protection for the internal cables, which can easily lead to the spread of the fire and even cause secondary disasters.

[0006] To achieve the above objectives, this utility model provides a fireproof cable tray, including a frame, and a movable frame sleeved on the outer side of the frame, with a spray plate fixedly connected to the top inner side of the movable frame.

[0007] A pump body is bolted to one side of the outer wall of the frame, and the outlet of the pump body is connected to one side of the spray plate. A cleaning brush is fixedly connected to the bottom inner side of the moving frame, and the top of the cleaning brush is in contact with the bottom of the frame. Both sides of the cleaning brush are equipped with air collection hoods fixedly connected to the bottom inner side of the moving frame. One side of the two air collection hoods are connected to each other through a connecting pipe. A fan is bolted to one side of the outer wall of the frame, and the inlet of the fan is connected to one end of the connecting pipe. A fixing plate is fixedly connected to one side of the frame, and a cylinder is bolted to one side of the fixing plate. The output shaft of the cylinder passes through the fixing plate and is fixedly connected to one side of the moving frame.

[0008] The inner top sides of the movable frame are fixedly connected to sliders, and both sliders are slidably connected to the top of the frame through a groove.

[0009] One side frame is fixedly connected to one side of the frame, and a sliding rod is fixedly connected to the inside of the side frame. A sliding sleeve is fitted on one end of the sliding rod, and one side of the sliding sleeve is fixedly connected to one side of the movable frame.

[0010] The pump body has a connecting pipe at its outlet, and one end of the connecting pipe is connected to one side of the spray plate.

[0011] The fan inlet is connected to a duct, and one end of the duct is connected to one end of the connecting pipe.

[0012] The cylinder's output shaft is slidably connected to the fixed plate.

[0013] This utility model discloses a fireproof cable tray that utilizes an automatic fire extinguishing system combining a spray plate and a pump. This system responds rapidly in the early stages of a fire, spraying extinguishing liquid to effectively suppress the spread of fire and improve the overall safety of the electrical system. Secondly, to address the lack of active smoke extraction capabilities in the cable tray structure, a smoke extraction device consisting of a fan, a hood, and a connecting pipe is introduced. This device can promptly remove dense smoke generated during a fire, improving visibility and reducing the risk of secondary injuries. Thirdly, considering the susceptibility of cable trays to environmental influences during long-term use, an automatic cleaning structure with a cylinder-driven moving frame and cleaning brush is specially designed. This structure can periodically remove dust and foreign objects from the bottom of the cable tray, extending its service life, reducing maintenance frequency, and improving daily management efficiency. Furthermore, all functional modules adopt a modular design; for example, the pump, fan, and cylinder are all bolted to the frame, facilitating installation, disassembly, and replacement, thus improving the maintainability and adaptability of the equipment.

[0021] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0022] Please see Figure 1-5 ,

[0023] A fireproof cable tray includes a frame 1, and a movable frame 5 is sleeved on the outside of the frame 1, and a spray plate 8 is fixedly connected to the top of the inner side of the movable frame 5.

[0024] A pump body 9 is bolted to one side of the outer wall of frame 1, and the outlet of pump body 9 is connected to one side of spray plate 8. A cleaning brush 15 is fixedly connected to the bottom inner side of movable frame 5, and the top of cleaning brush 15 is attached to the bottom of frame 1. Both sides of cleaning brush 15 are provided with air collection hoods 16 fixedly connected to the bottom inner side of movable frame 5. The two air collection hoods 16 are connected to each other through a connecting pipe 17. A fan 11 is bolted to one side of the outer wall of frame 1, and the inlet of fan 11 is connected to one end of connecting pipe 17. A fixing plate 13 is fixedly connected to one side of frame 1, and a cylinder 14 is bolted to one side of fixing plate 13. The output shaft of cylinder 14 passes through fixing plate 13 and is fixedly connected to one side of movable frame 5.

[0025] First, the cables are bundled and installed to frame 1, completing the cable arrangement and fixation. Then, cylinder 14 is activated, its output shaft pushing the moving frame 5 along the outer side of frame 1 via fixed plate 13. During this process, cleaning brush 15 moves synchronously with the moving frame 5 and adheres to the bottom surface of frame 1, thereby cleaning dust, dirt, and other impurities that may be attached to the bottom of the cable tray, preventing these impurities from accumulating for a long time and affecting the structural stability of the cable tray or causing corrosive damage to the cables. Simultaneously, the air collection hoods 16 located on both sides of the cleaning brush 15 move with the moving frame 5, always remaining near the cleaning area to collect dust particles raised during the cleaning process. Fan 11... Simultaneously activated, the system extracts air from the two gas collection hoods 16 through the connecting pipe 17, creating a negative pressure environment that effectively absorbs and removes dust generated during cleaning, preventing pollution of the surrounding environment. When a fire occurs, the system automatically or manually activates the pump 9, which is connected to an external fire extinguishing liquid storage tank via a pipeline. The fire extinguishing liquid is then delivered to the spray plate 8 and evenly sprayed onto the frame 1 and its surrounding area, achieving rapid fire extinguishing and fire source isolation. At the same time, the fan 11 continues to operate, drawing in dense smoke generated at the fire scene through the gas collection hoods 16 and discharging it to a safe area through the connecting pipe 17, achieving the purpose of smoke extraction and cooling, further ensuring the safety of personnel evacuation and firefighting operations.

[0026] Furthermore, sliders 6 are fixedly connected to both sides of the inner top of the moving frame 5, and both sliders 6 are slidably connected to the top of the frame 1 through the slide groove 7. When the moving frame 5 slides along the outside of the frame 1, the sliders 6 slide synchronously along the slide groove 7, which ensures the stability and guidance of the moving frame 5 during the movement process, and avoids the cleaning brush 15 from not fitting tightly or the spraying angle of the spray plate 8 from deviating due to offset or shaking, thereby achieving the effect of improving the overall structural stability and movement accuracy.

[0027] Furthermore, a side frame 2 is fixedly connected to one side of the frame 1, and a sliding rod 3 is fixedly connected to the inner side of the side frame 2. A sliding sleeve 4 is fitted onto one end of the sliding rod 3. One side of the sliding sleeve 4 is fixedly connected to one side of the moving frame 5. During the process of the cylinder 14 driving the moving frame 5 to move, this structure provides additional support and auxiliary guidance for the moving frame 5, enhancing the structural rigidity and motion reliability of the cable tray during long-term operation or frequent movement, thereby achieving the effect of improving the overall load-bearing capacity and operational stability of the device.

[0028] Furthermore, a connecting pipe 10 is connected to the outlet of the pump body 9, and one end of the connecting pipe 10 is connected to one side of the spray plate 8. Through the cooperation between the pump body 9 and the connecting pipe 10, the connecting pipe 10 efficiently transmits the extinguishing liquid output by the pump body 9 to the spray plate 8, ensuring the continuity and sealing of the extinguishing liquid delivery process, avoiding liquid leakage or pressure loss from affecting the spraying effect, thereby achieving the technical effect of ensuring rapid response, uniform spraying and wide coverage of the fire extinguishing system.

[0029] Furthermore, the inlet of the fan 11 is connected to the duct 12, and one end of the duct 12 is connected to one end of the connecting pipe 17. During the smoke exhaust process, the fan 11 drives the air inside the smoke collection hood 16 to flow through the duct 12, forming a stable negative pressure environment, which effectively improves the efficiency of smoke extraction and the speed of smoke exhaust at the fire scene, thereby achieving the purpose of enhancing the response capability and practical application effect of the smoke exhaust system.

[0030] Furthermore, the output shaft of cylinder 14 is slidably connected to the connection point of fixed plate 13.

[0031] In summary:

[0032] First, the cable is fixedly bundled to frame 1, completing the cable arrangement and installation. Then, cylinder 14 is activated, its output shaft pushing the moving frame 5 along the outside of frame 1 via fixed plate 13. During this process, slider 6 slides synchronously along slide groove 7, while sliding sleeve 4 slides along slide rod 3. Both work together to provide guidance and auxiliary support for the moving frame 5, ensuring its stable operation. Cleaning brush 15 moves synchronously with the moving frame 5, always adhering to the bottom surface of frame 1, cleaning adhering dust, dirt, and other impurities to prevent accumulation that could affect the stability of the cable tray structure or cause corrosive damage to the cables. Simultaneously, air collection hoods 16, located on both sides of the cleaning brush 15, also move with the moving frame 5, always remaining near the cleaning area for... The system collects dust particles raised during the cleaning process. Simultaneously, the fan 11 starts and connects to the connecting pipe 17 via the air duct 12, driving the air inside the two gas collection hoods 16 to be drawn out, forming a negative pressure environment, effectively adsorbing and discharging the dust generated during cleaning, and avoiding pollution of the surrounding environment. When a fire occurs, the system automatically or manually starts the pump body 9, which delivers external fire extinguishing liquid to the spray plate 8 through the connecting pipe 10, and the spray plate 8 evenly sprays it onto the frame 1 and its surrounding area, achieving the functions of rapid fire extinguishing and fire source isolation. At the same time, the fan 11 continues to run, drawing in the dense smoke generated at the fire scene through the gas collection hood 16 and discharging it to a safe area through the connecting pipe 17, achieving the purpose of smoke exhaust and cooling, and further ensuring the safety of personnel evacuation and fire fighting operations. First, the sliding connection structure between frame 1 and movable frame 5, along with the coordinated arrangement of side frame 2, sliding rod 3, and sliding sleeve 4, provides good guidance and structural support for movable frame 5, making the movement process more stable and reliable. This effectively prevents loose contact of cleaning brush 15 or deviation of spray angle of spray plate 8 caused by shaking or offset, thereby improving the overall device's operational accuracy and service life. Second, the cleaning and dust removal system composed of cleaning brush 15, fan 11, air collection hood 16, and connecting pipe 17 can automatically clean the bottom of the cable tray regularly during daily use and remove dust in a timely manner through negative pressure adsorption. This not only reduces the frequency of manual maintenance but also significantly improves the sanitary conditions of the environment where the cable tray is located, extending its service life. This extends the service life of the cable trays and cables; secondly, the automatic fire extinguishing system formed by the spray plate 8 and the pump body 9 through the connecting pipe 10 can respond quickly in the event of a fire, evenly spraying the extinguishing liquid to key areas, effectively suppressing the spread of fire and improving the safety of the electrical system; in addition, the smoke exhaust system composed of the fan 11, the duct 12, the gas collection hood 16 and the connecting pipe 17 can quickly draw in and exhaust dense smoke in the event of a fire, reducing the temperature and visibility obstacles on site, and improving the efficiency of escape and rescue; finally, the cylinder 14 and the fixed plate 13 adopt a sliding connection, which gives the drive system a certain fault tolerance in reciprocating motion, reduces mechanical wear and jamming, and improves the power transmission efficiency and the smoothness of equipment operation.In summary, this fire-resistant cable tray not only solves the technical defects of traditional cable trays in terms of poor fire resistance, lack of active cleaning methods and smoke extraction capabilities, but also achieves several innovations in structural stability, system integration and intelligence. It can better meet the comprehensive needs of modern buildings for cable laying equipment in terms of safety, environmental protection and efficient operation and maintenance.
