[0002] Cable troughs are used to accommodate cables and support the weight of the cables, and are widely used in areas such as factories with large power consumption and construction sites. Since the current flowing through the high-voltage cables is relatively large, the traditional cable trough boxes generally have poor heat dissipation effects. When the external environmental temperature is too high, it will further hinder heat dissipation. When the temperature exceeds a certain limit, it is extremely easy to cause a fire. The Chinese utility model patent with the application number 201720380393.2 discloses a double-layer cable trough box with good heat dissipation effect, which includes a cable trough box and a box cover arranged on the top of the cable trough box. First magnets and second magnets are respectively arranged on the outer walls of the left and right ends of the cable trough box, and a plurality of ventilation holes are respectively arranged on the outer walls of the front and back sides of the cable trough box. A horizontal partition is arranged inside the cable trough box, and the horizontal partition divides the cable trough box into a top interval and a bottom interval. A vertical partition is arranged inside the top interval, and the vertical partition divides the top interval into two left and right weak current troughs. A shielding layer is arranged on the inner wall of the weak current trough, and a plurality of radiators are arranged inside the bottom interval. Through the radiators and the ventilation holes, the heat generated by the high-voltage cables can be better dissipated, preventing the temperature from being too high, having good heat dissipation performance and higher safety.

[0003] However, the above cable box has a closed structure, the partition inside the cable box is a solid partition, and there are no heat dissipation holes on it, so the heat dissipation effect is not ideal; and the partition cannot be disassembled, which is not convenient for installing and maintaining the cables inside the cable trough in a closed space.

[0023] The present utility model will be further described below with reference to the accompanying drawings.

[0024] All orientations mentioned in this specification are subject to the orientation when a cable trough with rapid heat dissipation of the present utility model is working properly, and do not limit its orientation during storage and transportation. They only represent relative positional relationships and do not represent absolute positional relationships.

[0025] As Figures 1 to 4 As commonly shown, a cable trough with rapid heat dissipation includes a strip-shaped trough body 1 with an upper opening. A plurality of heat dissipation holes 2 are arranged at intervals on the bottom wall of the trough body 1; a lower vertical plate 3 perpendicular to the bottom wall of the trough body 1 is fixedly arranged inside the trough body 1. Above the lower vertical plate 3, a horizontal plate 4 parallel to the bottom wall of the trough body 1 is provided. The horizontal plate 4 is detachably connected between the left and right side walls of the trough body 1; above the horizontal plate 4, an upper vertical plate 5 perpendicular to the horizontal plate 4 is detachably provided; the lower vertical plate 3, the horizontal plate 4 and the upper vertical plate 5 together form a cross-shaped structure extending along the length direction of the trough body 1 inside the trough body 1, thereby dividing the internal space of the trough body 1 into four independent intervals for storing cables, namely up, down, left and right; the lower vertical plate 3, the horizontal plate 4 and the upper vertical plate 5 are all hollow plates, and round holes 6 for heat dissipation penetrating through the two plate surfaces of the hollow plates are arranged at intervals on the plate surfaces of the hollow plates.

[0026] Further, the lower vertical plate 3 is fixedly arranged in the middle of the bottom wall of the trough body 1, dividing the internal space of the trough body 1 into two equal parts, left and right; sliding grooves 7 are provided on the left and right side walls of the trough body 1, and the sliding grooves 7 are located in the middle of the side walls of the trough body 1. The horizontal plate 4 is slidably connected in the sliding grooves 7, and the horizontal plate 4 divides the internal space of the trough body 1 into two equal parts, up and down; the center line of the upper vertical plate 5 coincides with the extension line of the center line of the lower vertical plate 3. The lower vertical plate 3 is located at the bottom of the horizontal plate 4 and the upper vertical plate 5 and plays a supporting role. The lower vertical plate 3, the horizontal plate 4 and the upper vertical plate 5 together divide the internal space of the trough body 1 into four independent intervals, namely up, down, left and right; the lengths of the lower vertical plate 3, the horizontal plate 4 and the upper vertical plate 5 are equal to the length of the trough body 1, separating the space inside the entire trough body 1; a trough-shaped strengthening part 10 with a downward opening is formed by bending the middle part of the bottom wall of the trough body 1 upward, making the load-bearing capacity of the trough body 1 stronger.

[0027] Further, a sliding rail 8 is fixedly arranged on the upper surface of the horizontal plate 4, and a slider 9 is fixedly arranged at the bottom of the upper vertical plate 5. The slider 9 can be inserted into the sliding rail 8 and can slide in the sliding rail 8; a protrusion extending towards the center of the sliding rail 8 is provided at the upper end of the sliding rail 8, which can prevent the slider 9 from falling off.

[0028] Further, at the center line of the horizontal plate 4, a number of ventilation holes 11 are provided at intervals. The ventilation holes 11 sequentially penetrate through the upper and lower plate surfaces of the horizontal plate 4, the upper side surface of the lower vertical plate 3, and the lower side surface of the upper vertical plate 5, so that the internal cavities of the lower vertical plate 3, the horizontal plate 4, and the upper vertical plate 5 communicate with each other. The plurality of ventilation holes 11 are evenly distributed along the length direction of the trough body 1; the ventilation holes 11 are waist-shaped holes, the length of the ventilation holes 11 extends along the length direction of the trough body 1, and the width of the ventilation holes 11 is smaller than the thickness of the thinnest part between the lower vertical plate 3 and the upper vertical plate 5; the ventilation holes 11 can enhance the air fluidity between the four independent intervals for storing cables in the trough body 1 and accelerate the heat dissipation speed of the cables at the center of the trough body 1.

[0029] Further, the openings at one end of the lower vertical plate 3, the horizontal plate 4, and the upper vertical plate 5 are connected to the air outlet of the ventilator. When the temperature inside the cable trough is relatively high, the fan can be started to blow air into the cavities of the lower vertical plate 3, the horizontal plate 4, and the upper vertical plate 5. The blown air is evenly diffused into the cable trough through the round holes 6 on the plate surface to dissipate heat from the cables in the cable trough, so as to improve the heat dissipation efficiency.

[0030] During use, first divide the cables to be wired into four equal parts. Place the first part and the second part in the left and right intervals at the lower part of the trough body 1 respectively. Then install the horizontal plate 4 into the sliding groove 7 on the side wall of the trough body 1, install the upper vertical plate 5 into the sliding rail 8 on the horizontal plate 4, and then place the third part and the fourth part of the cables in the left and right intervals at the upper part of the trough body 1 respectively, and the installation is completed. The hot air inside the trough body 1 will be dissipated through the round holes 6 on the lower vertical plate 3, the horizontal plate 4, and the upper vertical plate 5, realizing air convection and heat exchange, and achieving a good heat dissipation effect on the inside of the trough body 1; if the cables need to be disassembled and repaired, the same method is used.

[0031] Certainly, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions, or substitutions made by those skilled in the art within the scope of the essence of the present invention should also fall within the protection scope of the present invention.
