AI Technical Summary
In cold storage environments, gaps are easily generated when cables pass through the wall, resulting in poor cold bridge effect, affecting electrical safety and cooling capacity retention.
A cable through-wall structure for cold storage anti-cold bridges is designed, including thermal insulation tiles, cable trays, honeycomb-like cable casings and fire-resistant cotton fillings. A soft wrapping material is provided inside the cable casing to fill the gaps.
The thermal insulation effect of the soft wrapping material to fill the gaps and fire-resistant cotton fillers effectively prevents the cold bridge effect, ensures electrical safety and reduces heat transfer.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of cable passing through walls, and particularly relates to a cable passing through wall structure for preventing cold bridges in cold storages. Background Technique
[0002] In a cold storage environment, due to its special temperature conditions, the structure and method of cables passing through walls must take into account preventing cold loss, avoiding the cold bridge effect, and ensuring electrical safety. The walls of cold storages usually have good heat insulation performance to maintain the internal low-temperature environment. Therefore, special treatment is required when cables pass through these walls. When carrying out special treatment, a wall-passing structure is often set on the cold storage wall. However, since the cable has a hard and non-deformable structure, it is easy to cause gaps when the cable passes through the wall-passing structure. For example, in patent CN202322080148.8, ultimately resulting in a poor cold bridge prevention effect.
[0003] To solve the above problems, the utility model hopes to provide a cable passing through wall structure for preventing cold bridges in cold storages. Content of the Utility Model
[0004] The purpose of the utility model is to provide a cable passing through wall structure for preventing cold bridges in cold storages to solve the problems raised in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solutions:
[0006] A cable passing through wall structure for preventing cold bridges in cold storages includes a heat insulation tile. A cable bridge is arranged in the heat insulation tile. A plurality of cable sleeves distributed in a honeycomb shape are arranged inside the cable bridge. Fireproof cotton filler is arranged between the cable sleeves and the cable bridge. Soft wrapping material is arranged inside the cable sleeves.
[0007] Preferably, the heat insulation tile includes a first insulation board, a wall body, and a second insulation board stacked in sequence.
[0008] Preferably, the cross-section of the cable sleeve is a regular hexagon, and the plurality of cable sleeves are closely arranged in a honeycomb array.
[0009] Preferably, the cross-section of the cable sleeve is a regular hexagon, and soft wrapping material is arranged at six side walls of the cable sleeve.
[0010] Compared with the prior art, the beneficial effects of the utility model are:
[0011] (1) For the cable passing through wall structure for preventing cold bridges in cold storages provided by the utility model, soft wrapping material is arranged inside the cable sleeve. After the cable is inserted into the cable sleeve, the soft wrapping material is extruded and fills the remaining gaps;
[0012] (2)The cable through-wall structure for preventing cold bridges in a cold storage provided by the present utility model is provided with a fireproof cotton filler between the cable tray and the cable sleeve, which can effectively generate a heat insulation effect;
[0013] (3)The cable through-wall structure for preventing cold bridges in a cold storage provided by the present utility model includes a heat insulation tile, a first insulation board, a wall body, and a second insulation board stacked in sequence. Through the first insulation board and the second insulation board, the heat transfer to the cable tray can be effectively reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0017] A cable through-wall structure for preventing cold bridges in a cold storage includes a heat insulation tile 1. A cable tray 2 is provided in the heat insulation tile 1, and the cable tray 2 penetrates through the heat insulation tile 1. The heat insulation tile 1 includes a first insulation board 3, a wall body 4, and a second insulation board 5 stacked in sequence. The arrangement of the first insulation board 3 and the second insulation board 5 can effectively reduce the heat transfer to the cable tray 2. A number of cable sleeves 6 distributed in a honeycomb shape are provided inside the cable tray 2. In order to reduce the heat transfer between the cable sleeve 6 and the cable tray 2, a fireproof cotton filler 7 is provided between the cable sleeve 6 and the cable tray 2. The cross-section of the cable sleeve 6 is a regular hexagon, and a number of cable sleeves 6 are closely arranged in a honeycomb array inside the cable bridge 2. The cross-section of the cable sleeve 6 is a regular hexagon, and soft wrapping materials 8 are provided at six side walls of the cable sleeve 6. Through extrusion, the soft wrapping material 8 can be deformed under pressure and fill the gap.
[0018] During use, take a cable to pass through the cable sleeve 6. At this time, the soft wrapping material 8 deforms, which can try to form the circular cross-section shape of the cable and prevent the appearance of gaps. For the cable sleeves 6 that do not need to pass through cables, take the same kind of soft wrapping material 8 to block these cable sleeves 6.
[0019] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
