Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, and in particular to a dustproof cover structure for a power distribution cabinet cable tray. Background Technology

[0002] In power systems, distribution cabinets are crucial equipment used for distributing electrical energy. Chinese utility model patent, authorized publication number "CN221552718U," discloses a distribution cabinet cable tray for improving wiring speed. Specifically, it provides a distribution cabinet cable tray that effectively improves wiring speed and accuracy. The cable tray includes a tray body, partitions, and a top cover. This cable tray improves wiring speed and accuracy, reduces wiring errors and rework, and enhances work efficiency and safety. Simultaneously, it facilitates wire maintenance and repair, extends wire lifespan, and has significant economic and social value.

[0003] The above technical solution facilitates the quick threading and connection of wires through the design and configuration of the cable tray. By dividing the tray into multiple areas and using partitions for separation, it can effectively prevent wire tangling and facilitate maintenance and repair. However, the above technical solution still has certain drawbacks. For example, although the above equipment facilitates the quick threading and connection of wires through the design and configuration of the cable tray, the cables in the distribution cabinet have various specifications and thicknesses. If the tooth spacing is fixed, thicker cables may not be able to pass through the tooth gap smoothly, and forcing them through may damage the cable sheath. For thinner cables, the tooth gap is too large, which will cause the cables to be not firmly fixed in the tray and are prone to shaking, affecting the neatness and stability of the wiring. When the equipment vibrates during operation, it may also cause problems such as cable wear or poor contact. Utility Model Content

[0028] Please see Figure 1-4 This utility model provides a technical solution: a dustproof cover structure for a power distribution cabinet cable tray, including a tray body 1 and a dustproof cover 4;

[0029] The tank body 1 is equipped with four limiting devices;

[0030] The limiting device includes a fixed mounting block 5, a rotating block 8, a threaded rod sleeve 9, a limiting block 10, and multiple wide teeth 3. The groove 1 is U-shaped, and the fixed mounting block 5 is H-shaped. Fixed mounting block slots 6 are provided on both sides of the upper end of the groove 1. T-shaped blocks 7 are fixedly connected to the lower ends of the multiple wide teeth 3. The outer walls of the multiple T-shaped blocks 7 are slidably connected to the interior of the corresponding fixed mounting block slots 6. Four rotating block slots 14 are provided on the lower surface of the groove 1. The rotating block 8 is rotatably connected to the inner wall of the corresponding rotating block slot 14. Two second limiting block slots 13 are provided on the inner walls of the two fixed mounting block slots 6. The limiting block 10 is slidably connected to the interior of the corresponding second limiting block slot 13. The outer wall of the fixed mounting block 5 is slidably connected to the interior of the corresponding fixed mounting block slot 6. The inner wall of the second limiting block groove 13 is provided with a rotating threaded rod 12. The end of the rotating threaded rod 12 near the limiting block 10 is rotatably connected to the outer wall of the limiting block 10. The threaded rod sleeve 9 is rotatably connected to the inner wall of the corresponding second limiting block groove 13. The outer wall of the end of the rotating threaded rod 12 away from the limiting block 10 is threadedly connected to the inside of the threaded rod sleeve 9. The end of the threaded rod sleeve 9 away from the limiting block 10 extends rotatably into the interior of the rotating block groove 14 and is fixedly connected to one end of the corresponding rotating block 8. The lower surface of the fixed mounting block 5 is provided with a first limiting block groove 11. The end of the limiting block 10 near the first limiting block groove 11 slides into the interior of the fixed mounting block groove 6 and contacts the inner wall of the first limiting block groove 11. The four limiting devices are respectively set at the four corners of the groove 1.

[0031] Among them, the dust cover 4 has multiple ventilation openings on its upper surface, each containing a dust net 2. The upper ends of the multiple wide teeth 3 are all arc-shaped, and the lower ends of the dust cover 4 are arc-shaped on both sides and are fitted with the multiple wide teeth 3 to be installed on the groove 1.

[0032] Furthermore, when using this device, if it is necessary to install the dust cover 4, first align the two curved surfaces at the lower end of the dust cover 4 with the wide teeth 3 on the groove 1, then place the dust cover 4 downwards so that the wide teeth 3 fit tightly against the dust cover 4. Next, if it is necessary to adjust the position of the wide teeth 3, since the T-shaped block 7 fixedly connected to the lower end of the wide teeth 3 is slidably connected to the inside of the fixed mounting block groove 6, the wide teeth 3 can be manually slid within the fixed mounting block groove 6 to a suitable position. When it is necessary to remove the wide teeth 3, rotate the rotating block 8 inside the rotating block groove 14 on the lower surface of the groove 1. The rotating block 8 drives the threaded rod sleeve 9 fixedly connected to it to rotate inside the second limiting block groove 13. Because the rotating threaded rod 12... The threaded rod sleeve 9 is threadedly connected to the threaded rod 12, and one end is rotatably connected to the limiting block 10. Therefore, the rotation of the threaded rod sleeve 9 will cause the rotating threaded rod 12 to move within the second limiting block groove 13, thereby causing the limiting block 10 to slide within the second limiting block groove 13. The limiting block 10 slides away from the fixed mounting block 5, causing it to lose contact with the inner wall of the first limiting block groove 11. Then, after the fixed mounting block 5 is removed, the wide tooth 3 loses its limiting position and can be removed from the groove 1. At the same time, during the normal operation of the power distribution cabinet cable tray, the dustproof net 2 on the dustproof cover 4 can prevent dust, debris, etc. from entering the interior of the groove 1 through the ventilation opening, ensuring the cleanliness of the internal wiring. At the same time, the ventilation opening ensures the ventilation and heat dissipation of the cable tray, maintaining the normal operating temperature of the wiring.

[0033] Because the T-shaped block 7, which is fixedly connected to the lower end of the wide tooth 3, is slidably connected to the inside of the fixed mounting block groove 6 in the limiting device, the wide tooth 3 can be slid directly and manually in the fixed mounting block groove 6. The wide tooth 3 can be slid along the fixed mounting block groove 6 to a suitable position. In this way, the distance between the wide teeth 3 can be adjusted according to the cable specifications in the power distribution cabinet, which effectively improves the practicality and flexibility of the cable tray.

[0034] Structural Description: Tunnel 1: U-shaped, is the main structure of the distribution cabinet cable tray, used to accommodate wires and cables. The upper two sides of the tunnel 1 have fixed mounting block slots 6 to provide space for the installation of fixed mounting blocks 5. The lower surface has four rotating block slots 14 for installing rotating blocks 8. Limiting devices are set at the four corners to fix the dust cover 4. At the same time, its internal space provides space for the wiring.

[0035] Dustproof net 2: Installed in the multiple ventilation openings on the upper surface of the dustproof cover 4. Its main function is to ensure ventilation and heat dissipation of the cable tray while preventing dust and debris from entering the inside of the tray 1, so as to avoid dust accumulation affecting the normal operation of the line and the performance of the distribution cabinet.

[0036] Wide teeth 3: T-shaped blocks 7 are fixedly connected to the lower ends of multiple wide teeth 3. Their outer walls are slidably connected to the interior of the corresponding fixed mounting block groove 6, and can slide within the fixed mounting block groove 6. The upper end of the wide teeth 3 is arc-shaped, which matches the arc surfaces on both sides of the lower end of the dust cover 4. When the dust cover 4 is installed on the groove 1, the wide teeth 3 can fit tightly with the dust cover 4, enhancing the dustproof effect and also helping to fix the dust cover 4.

[0037] Dust cover 4: Used to cover the tank 1 to prevent dust from entering the inside of the tank 1. Multiple ventilation holes are opened on its upper surface and dust net 2 is installed to ensure ventilation of the cable tray. The arc surfaces on both sides of the lower end cooperate with the wide teeth 3 to realize the installation connection with the tank 1, which plays the role of dust prevention and protection of internal circuits.

[0038] Fixed mounting block 5: It is "H" shaped and its outer wall is slidably connected to the inside of the corresponding fixed mounting block groove 6. It can slide in the fixed mounting block groove 6. Fixed mounting block 5 is an important part of the limiting device. By cooperating with other components, it can limit and fix the dust cover 4.

[0039] T-block 7: It is fixedly connected to the lower end of the wide tooth 3. Its outer wall is slidably connected to the inside of the corresponding fixed mounting block groove 6, so that the wide tooth 3 can slide stably in the fixed mounting block groove 6, thereby realizing the cooperation and installation with the dust cover 4 and ensuring the stability of the dust cover 4 after installation.

[0040] Rotating block 8: Rotatably connected to the inner wall of the corresponding rotating block groove 14, with one end fixedly connected to the threaded rod sleeve 9. By rotating the rotating block 8, the threaded rod sleeve 9 can be driven to rotate, thereby realizing the movement of the limit block 10 and playing the role of controlling the fixed state of the fixed installation block 5.

[0041] Threaded rod sleeve 9: Rotatably connected to the inner wall of the corresponding second limiting block groove 13, one end is fixedly connected to the rotating block 8, and the other end is threadedly connected to the rotating threaded rod 12. When the rotating block 8 rotates, the threaded rod sleeve 9 rotates accordingly. Through the threaded engagement with the rotating threaded rod 12, the rotating threaded rod 12 drives the limiting block 10 to slide in the second limiting block groove 13.

[0042] Limiting block 10: It is slidably connected inside the corresponding second limiting block groove 13. One end is rotatably connected to the rotating threaded rod 12, and the other end slides in the first limiting block groove 11 on the lower surface of the fixed mounting block 5. The limiting block 10 achieves the limitation of the fixed mounting block 5 by sliding in the second limiting block groove 13, thereby fixing the dust cover 4.

[0043] Rotating threaded rod 12: One end is rotatably connected to the outer wall of the limiting block 10, and the outer wall of the other end is threadedly connected to the inside of the threaded rod sleeve 9. Driven by the threaded rod sleeve 9, rotating threaded rod 12 can move within the second limiting block groove 13, thereby driving the limiting block 10 to slide, and realizing the limiting control of the fixed mounting block 5.

[0044] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
