[0002] At present, in the power supply system of large steel enterprises, the power supply of the electrical equipment installed on site is basically from the power distribution room to the site through the cable tunnel. Due to the large number of electrical equipment, the cables laid in the cable tunnel are relatively dense. In addition, many devices on site use low-voltage, high-power motors to run with load, resulting in large current-carrying capacity and high temperature of the cables. In the case of good ventilation, the maximum temperature of the cable surface can also exceed 80℃.

[0027] In order to make the skilled person in the technical field to which the present application belongs more clearly understand the present application, the technical solutions of the present application will be described in detail below with specific embodiments in conjunction with the accompanying drawings.

[0028] In the embodiments of the present application, as shown in the drawings, the cable support heat dissipation device comprises a support main body 1 and a cooling spray head 2; wherein, Figures 1 to 3

[0029] The support main body 1 is a block structure, so that the support main body 1 can be stably placed in a cable trench. In the present embodiment, the support main body 1 is a rectangular block structure, as shown in Figure 1 and Figure 2 A limiting groove 11 for placing a cable is arranged on each end surface of the support main body 1. The length direction of the limiting groove 11 is parallel to the length direction of the cable trench, that is, the length direction of the limiting groove 11 is in the same direction as the length direction of the cable laid in the cable trench. The support main body 1 is internally provided with a vent pipeline 12, and the end surface of the support main body 1 is provided with an air outlet 13, which is in communication with the vent pipeline 12.

[0030] The cooling spray head 2 comprises a spray nozzle 21 and a cooling hose 22, as shown in Figure 1 and Figure 3 The spray nozzle 21 is in communication with the air outlet 13 through the cooling hose 22.

[0031] When installing the cable support heat dissipation device, the support main body 1 can be placed in the cable trench. Since the support main body 1 is a rectangular block structure, the cable support heat dissipation device can be stably placed in the cable trench without the need for using other fasteners to reinforce it. Of course, the cable trench and the support main body 1 can be locked by adding fasteners such as screws and bolts, so that the cable support heat dissipation device can be more stably placed in the cable trench.

[0032] ​After the support body 1 is placed, the multiple cables in the cable groove can be separated one by one and placed in the multiple limiting grooves 11 on the support body 1, so that the gap between the multiple cables is increased, the laying density of the cables in the cable groove is reduced, and the heat dissipation effect of the cable surface is improved.

[0033] Meanwhile, the cold air is sprayed between the multiple cables by the cooling nozzle 2 to reduce the temperature in the cable groove and on the cable surface, so that the service life of the cable insulation material is not reduced due to the long time of the cable in the high temperature state.

[0034] It should be noted that the cold air can be provided by a vortex cooler; specifically, room temperature compressed air is first sent into the vortex cooler, and after being treated by the vortex cooler, it becomes dry compressed cold air (temperature between 25℃ and -45℃). The compressed cold air enters the cooling nozzle 2 through the air supply pipeline 12, and is sprayed between the multiple cables in the cable groove by the cooling nozzle 2 to achieve good cooling effect. The vortex cooler can provide cold air at 25℃ to -45℃. In the embodiment, the temperature of the compressed cold air provided by the vortex cooler is 5℃ to 15℃, and the compressed cold air at this temperature range can achieve good cooling effect on the cables.

[0035] Of course, since the support body 1 in the embodiment is a rectangular block structure, it can be fastened and matched with the cable groove without using other fasteners during installation, so the cable support and heat dissipation device can also be directly used for optimization of the cable groove that has been put into use, to improve the service life of the cable and reduce the safety hazard.

[0036] Preferably, the number of limiting grooves 11 is two groups, as shown in Figure 2 The two groups of limiting grooves are respectively arranged on the upper end face and the lower end face of the support body 1, wherein the lower end face of the support body 1 is used to contact the groove bottom of the cable groove, and the upper end face of the support body 1 is located on the side of the support body 1 away from the cable groove. This arrangement can better separate the multiple cables and maximize the gap between the multiple cables, so as to increase the contact area between the multiple cables and the air to improve the heat dissipation effect.

[0037] In some embodiments, the length of the cooling hose 22 is less than the distance from the air outlet 13 to the limiting groove 11.

[0038] Since the nozzle 21 is not fixed by fasteners, when the compressed cold air is sprayed outwards by the nozzle 21, the position of the nozzle 21 will change under the action of the reaction force of the compressed cold air, and at the same time, the nozzle 21 is constrained by the cooling hose 22, so that the nozzle 21 can only swing irregularly in a spherical surface with the length of the cooling hose 22 as the radius, thereby spraying cold air on the surrounding cables to achieve a good cooling effect. Of course, the length of the cooling hose 22 is less than the distance from the air outlet 13 to the limiting groove 11, which can avoid the nozzle 21 from hitting the cables during the swinging process.

[0039] In some embodiments, the air outlet 13 is provided with a connecting screw head, and the air inlet end of the cooling hose 22 is provided with a connecting nut matched with the connecting screw head. The cooling hose 22 is detachably connected to the air outlet 13 through the cooperation of the connecting nut and the connecting screw head, so that the installation and disassembly of the cooling hose 22 are more simple and convenient.

[0040] In some embodiments, the air inlet end of the air passage 12 is provided with a transparent air inlet hose 3, and the air passage 12 communicates with the air supply device through the air inlet hose 3.

[0041] The transparent air inlet hose 3 can facilitate observation of the inside condition. If foreign matter is blocked in the air inlet hose 3, maintenance personnel can quickly complete detection and maintenance, thereby reducing the maintenance difficulty of the cable cooling device.

[0042] In some embodiments, the air outlet end of the air inlet hose 3 is detachably connected to the air inlet end of the air passage 12, and the air inlet end of the air passage 12 is provided with a filter screen (not shown in the figure).

[0043] The filter screen can prevent foreign matter from entering the air passage 12, thereby preventing the air passage 12 or the cooling spray head 2 from being blocked. The filter screen can be cleaned through the detachable air inlet hose 3, so as to ensure the cleanliness of the filter screen, thereby enabling the cold air to smoothly pass through the filter screen into the air passage 12, flow through the air passage 12 to the cooling spray head 2, and be sprayed outwards by the cooling spray head 2.

[0044] In some embodiments, the air inlet end of the air inlet hose 3 is provided with a quick connector (not shown in the figure), and the air inlet hose 3 communicates with the air supply device through the quick connector, so that the cable support cooling device is more convenient to use.

[0045] In some embodiments, the number of the cooling spray heads 2 is two groups, and the two groups of cooling spray heads 2 are respectively arranged on the end faces of the support body 1 corresponding to the two ends of the limiting groove 11. The two groups of cooling spray heads 2 respectively cool the cables extending from the two ends of the limiting groove 11, thereby improving the cooling effect of the cable support cooling device. In some embodiments, the number of the cooling spray heads 2 is two groups, and the two groups of cooling spray heads 2 are respectively arranged on the end faces of the support body 1 corresponding to the two ends of the limiting groove 11. The two groups of cooling spray heads 2 respectively cool the cables extending from the two ends of the limiting groove 11, thereby improving the cooling effect of the cable support cooling device.

[0046] In some embodiments, the outer part of the support body 1 is covered with a buffer layer;

[0047] In the prior art, during the process of conveying the slab by the roller way, the cable groove installed below the roller way will generate vibration phenomenon, causing the cable to vibrate with the cable groove. In the long-term vibration environment, the friction between the cable groove and the cable will inevitably cause the abrasion of the cable surface, which is easy to cause the damage of the cable insulation protective layer and easily cause the cable short circuit.

[0048] In the present embodiment, the support body 1 can reduce the contact area between the cable supported by the support body 1 and the cable groove, and reduce the friction between the cable and the cable groove when the cable groove vibrates, thereby effectively avoiding the damage of the cable surface and improving the service life of the cable.

[0049] The buffer layer covering the outer part of the support body 1 can reduce the vibration and displacement of the cable on the support body 1 when the cable groove vibrates, thereby further avoiding the damage of the cable surface.

[0050] 1) The limiting groove 11 provided on the support device of the cable support and heat dissipation device can be used for placing and limiting the cable, separating the multiple cables in the cable groove, increasing the spacing between the multiple cables, and then spraying cold air between the multiple cables through the cooling nozzle 2 to reduce the temperature in the cable groove and the surface of the cable, thereby avoiding the situation that the service life of the cable insulation material is reduced due to the long-term high temperature of the cable, and effectively reducing the safety hazard of the cable groove in the use process.

[0051] 2) The support device of the cable support and heat dissipation device can reduce the contact area between the cable supported by the support body 1 and the cable groove, and reduce the friction between the cable on the support body 1 and the cable groove when the cable groove vibrates, thereby effectively avoiding the damage of the cable surface and improving the service life of the cable.

Therefore, the appended claims are intended to be interpreted as including all the changes and modifications falling within the scope of the present application.
