Description

New PVC trunking

technical field

The invention relates to the technical field of cable trunking, in particular to a novel PVC trunking.

Background technique

According to the requirements of the State Grid Corporation of China, the cables connected to the equipment inside the cabinet must be routed through the wire slots. At the same time, as the substation relies more and more on the information communication network, there are more and more related data cables inside the cabinet, which puts forward higher requirements for the wire slot. In actual work, because of the unreasonable design of the wire slot, it often affects the wiring work, and eventually leads to problems such as cable breakage and damage to the wire slot. At the same time, because the trunking itself is inconspicuous, few technicians optimize and improve it, but the cables in it are very important. Once a certain cable is interrupted, the relevant departments will be assessed at least, and the power grid accident will be caused at worst. In summary, it is necessary to optimize the trunking to ensure convenient and fast wiring for operation and maintenance personnel.

The traditional trunking, as shown in Figure 1, is composed of a cover plate 1 and a slot body 2, and there are gaps on the sides at intervals to facilitate the entry and exit of cables 3. In the process of laying cables, first uncover the cover plate 1, put the cable 3 into the wire slot from the opening of the slot body 2, and then put it in the designated position, and finally cover the cover plate 1 on the cable through the opening. Tank body 2. The fixing method of the cover plate 1 and the tank body 2 is fixed by PVC clips, as shown in Fig. 2 .

There are also some problems with this method, mainly including:

1. It is difficult to remove the cover plate 1. Since the height of the cover plate 1 is about 1800mm, due to the dense cables in the cabinet, other cables will affect the removal of the cover plate, making it difficult to complete smoothly.

2. After the cover plate 1 is removed, it is difficult to install it again. The main reason is that the tank body 2 is made of PVC plastic, long-term pressing and dismantling will cause the deformation of the wire slot body 2, and at the same time, the temperature in the cabinet itself is high, and it is easy to cause irreversible damage to it during the process of installing and removing the cover plate 1, resulting in failure. It was installed smoothly.

Contents of the invention

Aiming at the deficiencies of the prior art, the present invention proposes a novel PVC trunking, which has a simple structure and can conveniently and quickly lay cables.

In order to achieve the purpose of the above invention, the present invention provides the following technical solutions: a new type of PVC wire trough, including a trough body and a cover plate.

Further, the tank body is provided with two buckles, respectively clamping the two cover plates.

Further, the heights of the two cover plates are the same.

Further, the tank body is a C-shaped tank.

Further, the dislocation is that the two cover plates are buckled with the opening of the tank body so that the inside and outside are staggered.

Further, the opening of the tank body is provided with two flanges which are respectively slidingly matched with the two cover plates.

Further, the size of the cover plate is: length 700mm, width 100mm.

Compared with the prior art, the present invention has the following advantages: in order to avoid dismantling the new type C wire slot, avoid installing and removing the PVC cover plate during wiring, and avoid many problems in the process of pressing and removing the cover plate. The new C-line trunking without dismantling has the characteristics of simple structure, low cost, safety and reliability, etc. It is suitable for mass production, can significantly reduce the working pressure in wiring work, and improve the efficiency of operation and maintenance.

Detailed ways

The present invention will be described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory, and should not have any limiting effect on the protection scope of the present invention.

As shown in Figures 3 and 4, a new type of PVC trunking mainly includes a first cover 1, a second cover 4 and a slot body 3. The biggest difference from the traditional PVC trunking is that it contains two first A cover plate 1 and a second cover plate 4, and two buckles are designed on the tank body 3 to hold the first cover plate 1 and the second cover plate 4 respectively, so that the first cover plate 1 and the second cover plate 4 can be At the same time, the position can be adjusted freely. When laying cables, the wiring can be completed by overlapping the first cover 1 and the second cover 4 and adjusting the position at the same time, so that the wiring can be completed without removing the cover. The specific wiring is as follows: Figure 5 shows.

In addition, the PVC trunking is generally placed vertically in the cabinet. Since the first cover 1 and the second cover 4 are slidable, the first cover 1 and the second cover 4 need to be fixed after installation. The present invention uses Velcro to fix the cover plate, a nylon belt is installed on the side of the cover plate, hard bristles with hooks are installed on one side of the nylon belt, soft round hair is installed on the side of the tank body, and the fixing can be completed by using the magic belt.

As shown in Figure 6, the specific dimensions of the present invention are as follows: L1 and L2 are 700mm, M is 100mm, and N is 50mm.

The novel PVC trunking of the present invention adopts the sliding design of two cover plates, which avoids the phenomenon of needing to frequently press and remove the cover plates, and improves the working efficiency of wiring.

The cover is fixed by Velcro. When the Velcro is attached, the cover can be fixed, and when the Velcro is removed, the sliding performance of the cover can meet the requirements.

The above is only a preferred embodiment of the present invention, it should be pointed out that, for those of ordinary skill in the art, without departing from the principle of the present invention, some improvements and modifications can also be made, and these improvements and modifications can also be made. It should be regarded as the protection scope of the present invention.
