Description

Technical Field

[0001] This utility model relates to the field of cable trays, and specifically to an automatic drainage mechanism at the bottom of a cable tray. Background Technology

[0002] Cable trays are available in various structures, including trough type, tray type, ladder type, and mesh type, and consist of supports, brackets, and installation accessories. Cable trays can be installed independently within buildings or laid on various building structures and pipe rack supports.

[0003] Existing cable trays are basically U-shaped structures, with a cover plate on top and a sealed support plate at the bottom. Multiple through holes are spaced apart on both sides of the cable tray, located in the middle of the sides. When the cable tray is installed outdoors or in a damp factory environment, water easily accumulates inside because the bottom of the cable tray is sealed. Since the through holes are not parallel to the bottom surface of the cable tray, a small amount of water cannot drain in time and can only drain out when the water level is higher than the through holes. However, water below the through holes will continue to remain inside the cable tray cavity. Over time, this not only leads to corrosion and aging of the cable tray, but also poses a significant safety hazard because the lower half of the cable is constantly submerged in water.

[0004] Therefore, it is necessary to invent an automatic drainage mechanism for the bottom of cable trays. Utility Model Content

[0005] The purpose of this invention is to solve the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic drainage mechanism for the bottom of a cable tray, comprising a trough-type cable tray and through holes, wherein the through holes are spaced apart on both sides of the trough-type cable tray, a base is installed at the lower end of the inner cavity of the trough-type cable tray, and partition components are spaced apart on both sides of the base, and a fixing component is installed on the side of the partition component near the lower end of the base.

[0007] Based on the above features: the base is fixed at the bottom of the inner cavity of the trough-type cable tray, which facilitates the guidance of accumulated water to both sides, allowing the water in the trough-type cable tray to be discharged outward through the through holes. The setting of the separator component facilitates the bundling of cables when they pass through the inside of the trough-type cable tray, minimizing the accumulation or tangling of cables.

[0008] Preferably, the base has guide grooves symmetrically formed at both ends, and slots are formed at intervals at the bottom of the guide grooves.

[0009] Based on the above features: the guide groove facilitates guiding and limiting the two ends of the separator component, and the slot facilitates limiting and fixing the separator component after it has been moved to the required position.

[0010] Preferably, both the base and the guide groove are arranged in an arc shape.

[0011] Based on the above features: the guide groove is set in an arc shape, which facilitates the movement of the separator components in an arc shape outside the base.

[0012] Preferably, the separating component includes a separating plate and a connecting plate mounted on the upper end of the separating plate. The separating plate has a movable groove at one end near the fixed component, and a vertical rod is installed in the middle of the movable groove.

[0013] Based on the above features: there is a gap between the connecting plate and the base. On the one hand, the connecting plate can be connected to the partition plates on both sides to facilitate the limiting of the cable and prevent the cable from slipping to both sides. On the other hand, it ensures that water can be discharged through the guide hole in the gap.

[0014] Preferably, the fixing component includes a guide plate and a through groove at the lower end of the guide plate. A locking block is movably inserted into the through groove. A movable plate is fixedly installed on one side of the upper end of the locking block. A circular hole is opened in the middle of the movable plate.

[0015] Based on the above features: the locking block is movably passed through the through slot, and the end of the moving plate away from the locking block is movably passed through the movable slot, which makes it convenient for the operator to pull the locking block up and retract it to the inside of the guide plate by the moving plate. The upright rod inside the movable slot can pass through the round hole through the moving plate, which makes it convenient for the moving plate to move in a vertical state.

[0016] Preferably, a first magnet is installed on the inner wall of the upper end of the guide plate, and a limiting groove is formed on the inner wall of the side of the guide plate away from the moving plate.

[0017] Based on the above features: the guide plate can use the first magnet to spring the locking block downwards, while the limiting groove can guide and limit the locking block.

[0018] Preferably, a second magnet is fixedly installed on the upper end of the card block, and a limit slide is fixedly installed on the side of the card block away from the moving plate.

[0019] Based on the above characteristics: the magnetic poles of the first magnet and the second magnet are opposite to each other and they repel each other. When the moving plate is released, the first magnet can rebound in the opposite direction and the locking block can move down. At this time, the locking block can extend through the through slot and be locked into the inner side of the slot for limitation and fixation.

[0020] The beneficial effects of this utility model are:

[0021] 1. The base has an arc-shaped structure. When the base is installed inside the cable tray, its two sides must be higher than the bottom of the through hole. When there is water inside the cable tray, it is convenient for the water inside the cable tray to slide to the sides and be discharged through the through hole. When the cable passes through the inside of the cable tray, the base can support the cable from below. The partition component can bundle the cable to prevent the cable from sliding to the sides and to avoid the cable from piling up or getting tangled together.

[0022] 2. The spacing of the separator can be adjusted according to different diameters or numbers of cables. During adjustment, the locking block can be moved upward and retracted to the inside of the guide plate by first moving the moving plate. Then, the separator can be moved left and right. When the separator is moved to the required position, the first magnet and the second magnet repel each other due to their opposing magnetic poles. When the moving plate is released, the first magnet can rebound and the locking block can move downward, allowing the locking block to extend through the through slot and be locked inside the slot for limitation and fixation, thus improving the adjustability of the separator.

Detailed Implementation

[0028] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0029] See attached document Figure 1-4This utility model provides an automatic drainage mechanism for the bottom of a cable tray, including a trough-type cable tray 1 and through holes 2. The through holes 2 are spaced apart on both sides of the trough-type cable tray 1. The trough-type cable tray 1 has an overall U-shaped structure, which facilitates the passage of cables through the interior of the trough-type cable tray 1. The through holes 2 can be used for heat dissipation and drainage. A base 3 is installed at the lower end of the inner cavity of the trough-type cable tray 1. The base 3 can be fixed to the bottom end of the inner cavity of the trough-type cable tray 1 by welding or bolts, or it can be movably inserted into the inner cavity of the trough-type cable tray 1. There is no specific limitation. It is convenient to guide the accumulated water to both sides, so that the water in the trough-type cable tray 1 can be discharged outward through the through holes 2. Dividing components 4 are installed at intervals on both sides of the base 3 to facilitate the separation of cables when they pass through the interior of the trough-type cable tray 1, so as to avoid the cables from piling up or getting tangled together. A fixing component 5 is installed on the side of the dividing component 4 near the lower end of the base 3 to facilitate the fixing of the dividing component 4.

[0030] The base 3 has symmetrical guide grooves 31 at both ends to facilitate guiding and limiting the two ends of the separator component 4. The bottom of the guide groove 31 has slots 32 spaced apart to facilitate limiting and fixing the separator component 4 after it is moved to the required position. Both the base 3 and the guide groove 31 are arc-shaped. The base 3 is arc-shaped and its two sides need to be higher than the bottom of the through hole 2 when it is installed so that the water in the trough cable tray 1 can slide down to both sides and be discharged through the through hole 2. The guide groove 31 is arc-shaped so that the separator component 4 can move in an arc shape outside the base 3.

[0031] The separator assembly 4 includes a separator plate 41 and a connecting plate 42 mounted on the upper end of the separator plate 41. The separator plate 41 is mounted on both sides of the base 3 by a fixing assembly 5, while the connecting plate 42 is fixedly mounted in the middle of the end of the separator plate 41 away from the base 3. A gap is left between the connecting plate 42 and the base 3. On the one hand, the connecting plate 42 can be connected to the separator plates 41 on both sides to facilitate the limiting of the cable and prevent the cable from slipping to both sides. On the other hand, it can ensure that water can be discharged through the guide hole 2 in the gap. A movable groove 43 is opened at the end of the separator plate 41 near the fixing assembly 5. A vertical rod 44 is installed in the middle of the movable groove 43. When it is necessary to limit and bundle cables of different diameters or numbers, the fixing assembly 5 can be moved out of the slot 32 by the position of the movable groove 43. Then the separator assembly 4 can be moved to facilitate the adjustment of the distance between two adjacent separator assemblies 4. After the position of the separator assembly 4 is adjusted, the fixing assembly 5 can be loosened and inserted into the slot 32 for fixation.

[0032] The fixing component 5 includes a guide plate 51 and a through groove 52 at the lower end of the guide plate 51. The through groove 52 has the same diameter as the slot 32. A locking block 53 is movably inserted into the through groove 52. The locking block 53 passes through the through groove 52. A movable plate 54 is fixedly installed on one side of the upper end of the locking block 53. A round hole 55 is opened in the middle of the movable plate 54. The guide plate 51 can slide in an arc shape inside the guide groove 31. The end of the movable plate 54 away from the locking block 53 passes through the movable groove 43, which makes it convenient for the operator to pull the locking block 53 up and retract it to the inside of the guide plate 51. The upright rod 44 inside the movable groove 43 can pass through the round hole 55 through the movable plate 54, which makes it convenient for the movable plate 54 to move in a vertical state.

[0033] A first magnet 511 is installed on the inner wall of the upper end of the guide plate 51. A limiting groove 512 is opened on the inner wall of the guide plate 51 on the side away from the moving plate 54. A second magnet 531 is fixedly installed on the upper end of the locking block 53. A limiting slide plate 532 is fixedly installed on the side of the locking block 53 away from the moving plate 54. The limiting slide plate 532 is slidably connected to the limiting groove 512 to facilitate the vertical movement of the moving plate 54 and the locking block 53. The magnetic poles of the first magnet 511 and the second magnet 531 are opposite to each other and they repel each other. When the moving plate 54 is released, the first magnet 511 can rebound in the opposite direction and the locking block 53 moves down. At this time, the locking block 53 can extend through the through groove 52 and be locked into the inner side of the locking groove 32 for limiting and fixing, so that the separating component 4 cannot move on its own.

[0034] The usage process of this utility model is as follows: Before the cable passes through the inside of the trough-type cable tray 1, the base 3 can be installed at the bottom of the inner cavity of the trough-type cable tray 1 in advance. Then, the position between adjacent partition components 4 can be adjusted according to different diameters or numbers of cables. During adjustment, the locking block 53 can be pulled up and retracted to the inside of the guide plate 51 by the moving plate 54. Then, the partition component 4 can be pulled left and right to adjust. When the partition component 4 is moved to the required position, the through groove 52 can be aligned with the locking groove 32 at the bottom of the guide groove 31. Since the magnetic poles of the first magnet 511 and the second magnet 531 are opposite, they repel each other. When the moving plate 54 is released, the first magnet 511 can rebound in the opposite direction and the locking block 53 can move down, so that the locking block 53 can be extended through the through groove 52 and locked into the inner side of the locking groove 32 for limitation and fixation. When the cable passes through the inside of the trough-type cable tray 1, the cable can be limited between two adjacent partition components 4. Once water accumulates inside the trough-type cable tray 1, the water will slide to both sides through the base 3 and finally be discharged from the trough-type cable tray 1 through the through hole 2.

[0035] The above description is merely a preferred embodiment of this utility model. Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model are within the scope of protection claimed by this utility model.
