Detailed ways

In order to make the technical solutions and advantages of the embodiments of the present application more clear, the exemplary embodiments of the present application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, and Not all embodiments are exhaustive. It should be noted that the embodiments in the present application and the features of the embodiments may be combined with each other in the case of no conflict.

Example 1

As shown in FIG. 1 , this embodiment proposes an intelligent cooling cable tray system. The system includes a cable tray 1 , a heat exchange layer 3 and a temperature control device. A heat exchange plate 2 is provided under the bottom of the cable tray 1 . A heat exchange layer 3 is formed between the heat exchange plate 2 and the bottom of the cable tray 1. The bottom of the cable tray 1 is provided with a heat exchange hole 15, the side wall of the cable tray 1 is provided with an air outlet, and the heat exchange plate 2 is provided with an inlet. The air inlet, the temperature control device includes an air inlet fan 5 and an air outlet fan 6, and the air inlet fan 5 is arranged in the air inlet to flow the cold air outside the cable tray 1 into the inside of the cable tray 1 through the heat exchange hole 15, The air outlet fan 6 is arranged in the air outlet, and is used to flow out the hot air inside the cable tray 1 to the outside of the cable tray 1 .

Specifically, as shown in FIGS. 1 to 6 , in this embodiment, a heat exchange plate 2 is provided below the cable tray 1 , and a heat exchange layer 3 can be formed between the heat exchange plate 2 and the bottom of the cable tray 1 , and A heat exchange hole 15 is opened at the bottom of the cable tray 1 . The cable 4 can be normally laid in the wire groove of the cable tray 1 . The cable tray 1 may also be provided with a communication cable support 13 or other cable supports 14 and the like, so as to accommodate more cables 4 . Of course, the heat exchange plate 2 can also be arranged inside the cable tray 1, but it is very likely that the cables 4 cannot be properly accommodated due to occupying too much internal space.

The heat exchange plate 2 is provided with an air inlet, and an air inlet fan 5 is arranged at the air inlet. When the air intake fan 5 is in operation, the cold air outside the cable tray 1 can flow into the inside of the cable tray 1 through the heat exchange holes 15 at the bottom of the cable tray 1 . Due to the entry of cold air, the hot air inside the cable tray 1 is squeezed and flows to the side wall of the cable tray 1 . In order to make the hot air flow out of the cable tray 1 , an air outlet is provided on the side wall of the cable tray 1 in this embodiment, so that the hot air flows out to the outside of the cable tray 1 through the air outlet. At the same time, in order to make the air flow faster and keep the air temperature inside the cable tray 1 in a lower range, an air outlet fan 6 is also provided at the air outlet in this embodiment. The air inlet fan 5 and the air outlet fan 6 are turned on at the same time, so as to form a rapid flow of air and keep the temperature of the air inside the cable tray 1 relatively stable.

The above-mentioned air inlet fan 5 and air outlet fan 6 can control their working states manually, or can control their working states by automatic control. Specifically, in this embodiment, a temperature sensor 7 can also be provided in the wire groove of the cable tray 1 . The number and arrangement position of the temperature sensors 7 can be determined according to the actual wiring of the cables 4 and the structure of the cable tray 1 . The temperature sensor 7 can collect the temperature inside the cable tray 1 , and then report the collected real-time temperature to the processor 8 . After receiving the real-time temperature collected by the temperature sensor 7, the processor 8 compares the real-time temperature with the preset set temperature. When the real-time temperature is greater than the set temperature, the air inlet fan 5 and the air outlet fan 6 are turned on, and the cold air outside the cable tray 1 flows into the cable tray 1 through the air inlet fan 5 and the heat exchange hole 15, and the cables The hot air inside the cable tray 1 flows out to the outside of the cable tray 1 through the air outlet fan 6 . When the real-time temperature is less than or equal to the set temperature, the air inlet fan 5 and the air outlet fan 6 can be turned off to save energy and prolong the service life of the fans. The preset set temperature may be set and adjusted according to weather conditions in different regions, which is not particularly limited in this embodiment.

In addition, in order to adjust the temperature of the air inside the cable tray 1 more effectively, the air inlet fan 5 and the air outlet fan 6 can be set to multiple operating gears. When the real-time temperature is greater than the set temperature, that is, the air inside the cable tray 1 needs to be cooled, the operating gears of the air inlet fan 5 and the air outlet fan 6 can be adjusted accordingly according to the specific conditions of the real-time temperature. For example, it can be set that for every 5°C higher than the set temperature, the operating gears of the air inlet fan 5 and the air outlet fan 6 are increased by one level, and the corresponding fan speed is also increased for each level increase. Assuming that the set temperature is 35°C and the real-time temperature is 53°C, turn on the air inlet fan 5 and the air outlet fan 6, and increase the operating gear to the third gear, so that the air temperature inside the cable tray 1 drops rapidly set temperature.

Further, in order to make the air temperature in the cable tray 1 dissipate faster, in this embodiment, transverse fins 9 and longitudinal fins 10 can also be arranged in the heat exchange layer 3 to cross each other.

Furthermore, when the temperature inside the cable tray 1 is too high or other external force factors, it is very likely that the cable 4 will fail, such as a short circuit or the like, causing fire and burning. If this problem is not detected in time, it is likely to cause a serious fire. In order to solve this problem, a smoke sensor 11 may also be provided in the cable tray 1 in this embodiment. Likewise, the number and arrangement positions of the smoke sensors 11 can also be determined according to the actual wiring of the cables 4 and the structure of the cable tray 1 . The smoke sensor 11 can collect the real-time smoke concentration of the air inside the cable tray 1 and report the real-time smoke concentration to the processor 8 . The processor 8 receives the real-time smoke concentration collected by the smoke sensor 11, and compares the real-time smoke concentration with a preset set smoke concentration. When the real-time smoke concentration is greater than the set smoke concentration, fire alarm information is sent to the intelligent terminal 12 in a remote manner, and the operation and maintenance personnel are reminded to deal with it in time to avoid secondary expansion of the accident. In this embodiment, the smart terminal 12 is a mobile phone, a tablet, a PC or a background terminal. The sent fire alarm information may include information such as smoke concentration value, abnormal smoke point and the like. The way of alarm can include sound alarm, voice alarm, short message alarm, electronic map alarm and so on.
