Description
Technical Field
[0001] This utility model belongs to the field of waterproof cable tray technology, specifically relating to a waterproof multi-layer cable tray. Background Technology
[0002] With the development of electrical engineering, traditional single-layer cable trays have gradually revealed their shortcomings in terms of waterproofing, corrosion resistance, and load-bearing capacity. Especially in humid environments or outdoor use, water seepage can easily damage cables, and the single-layer structure cannot meet the needs of laying multiple cables. Therefore, a waterproof multi-layer cable tray has emerged. Through its multi-layer design and the application of waterproof materials, it effectively solves the defects of traditional cable trays, improving the safety and service life of cable laying.
[0003] However, the cables in existing waterproof multi-layered bridges are often left unattended. During windy or thunderstorms, the strong winds can cause the cables to shift, and water droplets on the inner wall of the cable tray can cause short circuits in the cables.
[0004] To address the aforementioned issues, this application proposes a waterproof, multi-layered bridge structure. Utility Model Content
[0005] To address the problems mentioned in the background section, this invention provides a waterproof, multi-layered cable tray that uses curved rods to clamp cables, thus fixing them in place and preventing cable misalignment.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a waterproof multi-layer cable tray, including a body one, a protruding plate fixedly connected to the bottom of the body one, a notch opened at the top of the body one, a body two placed at the bottom of the body one, a fixing rod one fixedly connected between the two inner walls of the body one, a fixing device provided inside the body one, and an arrangement device provided on the outer walls of the body one.
[0007] The fixing device includes a sleeve, which is rotatably connected to the circumferential surface of a fixing rod. A frame is fixedly connected to the circumferential surface of the fixing rod. Hollow blocks are provided on both sides of the frame. Two sliding rods are slidably connected to each other inside the hollow blocks. Protrusions are fixedly connected to both sides of the two sliding rods. Rotating plates are rotatably connected to the circumferential surfaces of the two sliding rods. The tops of the two rotating plates are rotatably connected via connecting plates. Arc-shaped rods are fixedly connected to the opposite sides of the two rotating plates. A fixing rod is fixedly connected to the side of the hollow block near the sleeve. A rotating rod is rotatably connected to the circumferential surface of the fixing rod. Two stops are fixedly connected to the side of the hollow block near the sleeve.
[0008] As a preferred embodiment of the waterproof multi-layered cable tray of this utility model, all the structures of the first body are present in the second body.
[0009] As a preferred embodiment of the waterproof multi-layered cable tray of this utility model, the side walls of the main body are provided with a number of ventilation holes, and the side walls of the main body are provided with drainage grooves.
[0010] As a preferred embodiment of the waterproof multi-layered cable tray of this utility model, an arc-shaped plate is fixedly connected to the inner bottom wall of the body, and the protrusion contacts the rotating rod.
[0011] As a preferred embodiment of the waterproof multi-layered cable tray of this utility model, the notch at the top of the second body contacts the convex plate at the bottom of the first body.
[0012] As a preferred embodiment of the waterproof multi-layered cable tray of this utility model, the rotating rod contacts the stop block, and a torsion spring is provided between the rotating rod and the second fixed rod.
[0013] An arrangement device is provided on one outer wall of the machine body.
[0014] The arrangement device includes two support blocks, which are symmetrically and fixedly connected to the outside of the body. A connecting rod is fixedly connected between the two support blocks, and a rotating block is rotatably connected to the circumferential surface of the connecting rod.
[0015] As a preferred embodiment of the waterproof multi-layered cable tray of this utility model, each of the rotating blocks is rotatably connected to a connecting block on the side near the support block, and a double-headed rod is fixedly connected to the bottom of the connecting block. Two arc-shaped frames are fixedly connected to both walls of the main body.
[0016] As a preferred embodiment of the waterproof multi-layered cable tray of this utility model, the double-headed rod of the second body contacts the arc-shaped frame of the first body.
[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: A fixing device is added to this application, which allows the cable to press down on the connecting plate, causing the connecting plate to rotate. At this time, the cable is limited and locked by the arc-shaped rod. When the protrusion moves, it passes through the rotating rod, where the rotating rod is blocked by a stop block to prevent the protrusion from resetting, thus fixing the cable and preventing it from moving or breaking. Simultaneously, a vent, a drainage channel, and an arrangement device are added. When it rains, rainwater can flow out through the drainage channel via the arc of the arc plate, while the vent increases ventilation and improves rainwater evaporation, helping the cable dissipate heat. The arrangement device can be hung on the arc-shaped frame at the first body via a double-headed rod at the second body, and then the rotating block can be pressed down to fix the first and second bodies, achieving a multi-layer effect suitable for environments with multiple cables.

[0026] 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 protection scope of the present utility model.
[0027] Example 1
[0028] like Figures 1 to 6 As shown;
[0029] A waterproof multi-layer cable tray includes a body 1, a protruding plate 4 fixedly connected to the bottom of the body 1, a notch opened at the top of the body 1, a body 2 placed at the bottom of the body 1, a fixing rod 51 fixedly connected between the two inner walls of the body 1, a fixing device 5 provided inside the body 1, and an arrangement device 6 provided on the outer walls of the body 1.
[0030] The fixing device 5 includes a sleeve 52, which is rotatably connected to the circumferential surface of a fixing rod 51. A frame 53 is fixedly connected to the circumferential surface of the fixing rod 51. Hollow blocks 54 are provided on both sides of the frame 53. Two sliding rods 511 are slidably connected inside the hollow blocks 54. Protrusions 57 are fixedly connected to both sides of the two sliding rods 511. Rotating plates 55 are rotatably connected to the circumferential surfaces of the two sliding rods 511. The tops of the two rotating plates 55 are rotatably connected via connecting plates 512. Arc-shaped rods 56 are fixedly connected to the opposite sides of the two rotating plates 55. A fixing rod 58 is fixedly connected to the side of the hollow block 54 near the sleeve 52. A rotating rod 59 is rotatably connected to the circumferential surface of the fixing rod 58. Two stops 510 are fixedly connected to the side of the hollow block 54 near the sleeve 52.
[0031] In this implementation scheme: First, the cable is placed on top of the connecting plate 512. When the cable moves downward, it will drive the connecting plate 512 to move downward. The downward movement of the connecting plate 512 will drive the two rotating plates 55 to rotate. At this time, the two rotating plates 55 will drive the two sliding rods 511 to move in opposite directions. When the two sliding rods 511 move in opposite directions, they will drive the protrusions 57 to move in opposite directions respectively. At this time, the two protrusions 57 will pass through the rotating rod 59. The rotating rod 59 and the stop block 510 will prevent the protrusions 57 from resetting. At this time, the arc rod 56 will clamp the cable to prevent the cable from moving or breaking in rainy or windy weather.
[0032] Furthermore:
[0033] In an optional embodiment, all the structures of the first body 1 are present in the second body 2. The side walls of the first body 1 are provided with a number of ventilation holes 11, the side walls of the first body 1 are provided with drainage grooves 12, and the inner bottom wall of the first body 1 is fixedly connected with an arc plate 3.
[0034] In this implementation plan: When it rains, when rainwater enters the interior of the machine body 1, the rainwater will flow through the top of the arc plate 3 towards the two walls of the machine body 1. At this time, the rainwater will flow out of the exterior of the machine body 1 through the drainage channel 12 to prevent rainwater accumulation and short circuit of the cable. The moisture inside the machine body 1 can be treated through the vent 11 to keep it dry.
[0035] Furthermore:
[0036] In an optional embodiment, the protrusion 57 contacts the rotating rod 59, and the notch at the top of the second body 2 contacts the protrusion 4 at the bottom of the first body 1.
[0037] In this implementation scheme: when the two protrusions 57 move in opposite directions, both protrusions 57 will contact the rotating rod 59. Also, when there are many cables, a second body 2 can be added so that the first body 1 can be connected to the second body 2.
[0038] Furthermore:
[0039] In an optional embodiment, the rotating rod 59 contacts the stop block 510, and a torsion spring is provided between the rotating rod 59 and the fixed rod 58.
[0040] In this embodiment: the stop block 510 can block the rotating rod 59, and the rotating rod 59 can limit the protrusion 57 to prevent the protrusion 57 from moving at will.
[0041] Furthermore:
[0042] In an optional embodiment, the outer wall of the body 1 is provided with an arrangement device 6;
[0043] The arrangement device 6 includes two support blocks 61, which are symmetrically fixedly connected to the outside of the body 1. A connecting rod 62 is fixedly connected between the two support blocks 61. A rotating block 63 is rotatably connected to the circumferential surface of the connecting rod 62. A connecting block 64 is rotatably connected to the side of the rotating block 63 near the support block 61. A double-headed rod 65 is fixedly connected to the bottom of the connecting block 64. Two arc-shaped frames 66 are fixedly connected to both walls of the body 1.
[0044] In this implementation plan: when there are multiple cables in the construction environment, the second body 2 can be taken out, the notch at the top of the second body 2 can be aligned with the protruding plate 4 at the bottom of the first body 1, and then the double-headed rod 65 on the outer wall of the second body 2 can be hung on the top of the arc frame 66 on the outer wall of the first body 1. Then, the rotating block 63 can be pushed down to fix the first body 1 and the second body 2. This is suitable for working environments with two cables. When there are several cables, more second bodies 2 can be installed to fix them and increase the firmness.
[0045] Furthermore:
[0046] In an optional embodiment, the double-headed rod 65 of the second body 2 contacts the arc-shaped frame 66 of the first body 1.
[0047] In this implementation scheme: the arc-shaped design of the arc frame 66 can prevent the double-headed rod 65 from falling off.
[0048] Working principle: First, the cable is moved into the machine body 1. When the cable moves downward, it contacts the connecting plate 512. As the cable continues to move downward, it drives the connecting plate 512 to move downward first. When the connecting plate 512 moves downward, it drives the two rotating plates 55 to rotate. When the two rotating plates 55 rotate, they drive the two sliding rods 511 to move in opposite directions. When the two sliding rods 511 move in opposite directions, they will respectively... The protrusion 57 is moved in the opposite direction. When the protrusion 57 moves, it will contact the rotating rod 59. As the protrusion 57 continues to move, it will cause the rotating rod 59 to rotate. When the protrusion 57 continues to move, it will disengage from the rotating rod 59. At this time, the rotating rod 59 will return to its original position under the elastic force of the torsion spring. When the cable disengages from the connecting plate 512, the bottom of the rotating rod 59 will contact the stop block 510. At this time, the rotating rod 59 will prevent the protrusion 57 from resetting. At this point, the cable will be completely secured, effectively preventing it from moving and from shaking and breaking in windy weather. When it rains, rainwater falling inside the fuselage 1 will contact the curved plate 3 and flow along its curvature towards the two walls of the fuselage 1. The rainwater will then flow out through the drainage channel 12, and external air can enter the fuselage 1 through the vent 11, allowing the rainwater inside the fuselage 1 to drain quickly. When multiple cables need to be bridged, several units 2 can be taken out. Align the notch at the top of unit 2 with the protruding plate 4 at the bottom of unit 1. After alignment, hang the double-headed rod 65 on the outer wall of unit 2 onto the top of the arc frame 66 on the outer wall of unit 1, and then push the rotating block 63 down. At this time, the double-headed rod 65 is in a taut state, which can fix unit 1 and unit 2. It can be used in the working environment of two cables. When there are several cables, more units 2 can be installed to fix them and increase the firmness.
[0049] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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.
