DETAILED DESCRIPTION

[0020] The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which presently preferred embodiments of the present invention are shown. However, the present invention can be implemented in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness, and will fully convey the scope of the invention to those skilled in the art.

[0021] Example 1

[0022] An electrical engineering cable protection device, such as Figure 1-Figure 5 As shown, it includes a box body 101, a handle 102 and a connecting plate 103; two handles 102 are connected to the left side of the box body 101, and the boxes 101 are arranged in two symmetrical distributions up and down, and the right sides of the two boxes 101 are connected by hinges, each box body 101 is connected to a handle 102, and each box body 101 is provided with four placement slots 10101 distributed left and right; each box body 101 is connected to a connecting plate 103;

[0023] Several first ventilation grooves 10102 are set in each placement groove 10101; several second ventilation grooves 10103 are set in each placement groove 10101, and the first ventilation grooves 10102 on the left and right sides of each placement groove 10101 are connected to a second ventilation groove 10103, and each first ventilation groove 10102 is connected to the interior of the box body 101.

[0024] The details of this application are as follows:

[0025] First, the user rotates the two boxes 101 to unfold them through the hinges, places the cable connection end to be protected in the placement groove 10101, and makes it fit the inner wall of the placement groove 10101. Then, the two boxes 101 are rotated closed through the hinges and fixed by passing bolts through the two connecting plates 103. At this time, there are several gaps between the cable connection end and the inner wall of the placement groove 10101. The first ventilation groove 10102 reduces the contact area with the cable connection end, so that the heat generated by the cable connection end during work can be smoothly discharged through the first ventilation groove 10102. In addition, the first ventilation groove 1010 2 can also allow outside air to enter and maintain air circulation in the placement groove 10101. Further, when a lot of heat accumulates in the placement groove 10101, making it difficult to discharge the heat, part of the heat can be directed to the box body 101 through the second ventilation groove 10103 connected to the first ventilation groove 10102, thereby increasing and dispersing the flow path of the air flow and improving the heat dissipation efficiency. Subsequently, the two boxes 101 can be rotated and unfolded by twisting out the bolts on the connecting plate 103, and the cable connection end can be taken out. Then, the user can close the two boxes 101 and carry the device by the handle 102, thereby improving the user's operating comfort.

[0026] Example 2

[0027] The air intake hood 201 is connected to the front and rear sides of each box body 101, and the air intake hood 201 is arranged in a truncated cone shape, with the end of the air intake hood 201 away from the box body 101 having a large diameter and the end close to the box body 101 having a small diameter; each air intake hood 201 is connected to a first connecting pipe 202; each first connecting pipe 202 is connected to a second connecting pipe 203, and the second connecting pipe 203 is connected to the second connecting pipe 206. The air grooves 10103 are connected; each first connecting tube 202 is rotatably connected to a rotating shaft 204, and the rotating shaft 204 extends through the first connecting tube 202 to the inside of the second connecting tube 203; a first fan blade 205 is fixedly connected to the bottom of each rotating shaft 204, and the first fan blade 205 is located inside the first connecting tube 202, and each blade of the first fan blade 205 has a vertically long longitudinal cross-section, which is used to increase the contact area with the airflow; a second fan blade 206 is fixedly connected to the upper part of each rotating shaft 204, and the second fan blade 206 is located inside the second connecting tube 203.

[0028] It also includes a connecting ring 301 and a drying ball 302; each placement slot 10101 is bolted to a connecting ring 301 on the front side; each connecting ring 301 is connected to a plurality of circumferentially distributed drying balls 302 on the rear side, and the drying balls 302 are located at the end of the first ventilation slot 10102, and the drying balls 302 are made of silicone material.

[0029] The details of this application are as follows:

[0030] When the user closes and fixes the two boxes 101, the external ambient air can be introduced through the air intake hood 201, and the cone shape of the air intake hood 201 can accelerate the flow rate of the ambient air, so that the ambient air enters the first connecting pipe 202, and the first fan blade 205 is driven to rotate by the incoming gas. It should be noted that the longitudinal cross-section of each blade of the first fan blade 205 is vertically long, which is used to increase the contact area with the airflow, ensuring that the airflow generates sufficient power to drive the first fan blade 205 to rotate after contacting it. Subsequently, the first fan blade 205 will drive the rotating shaft 204 and the second fan blade 206 to rotate, and the airflow generated by the rotation of the second fan blade 206 will be introduced into the placement slot 10101 through the second ventilation groove 10103, so that the ambient air flows out from the inside of the placement slot 10101 to the outside, thereby changing the flow direction of the heat inside the placement slot 10101 to the second ventilation groove 10103, so that the airflow enters the placement slot 10101 and takes the heat out from the inside to the outside, further accelerating the discharge of heat generated at the cable connection end.

[0031] Furthermore, when the ambient air is blown out from the placement slot 10101, it needs to pass through the first ventilation slot 10102. At this time, the moisture in the blown air can be dried by the drying ball 302, and the air in the placement slot 10101 can be dried, so that the air flow in the placement slot 10101 continues to flow while further enhancing the drying effect, avoiding the dangerous situation of electric shock caused by the cable connection end contacting moisture, and enhancing the protection effect of the cable connection end. Furthermore, when the drying ball 302 needs to be replaced, the user can remove the connecting ring 301 and replace the drying ball 302 to which it is connected. After the replacement is completed, the connecting ring 301 is reconnected to the box body 101 by bolts, thereby completing the replacement of the drying ball 302 and improving work convenience.

[0032] Example 3

[0033] Three through holes 10201 are provided in the middle of the handle 102 to facilitate the user's fingers to pass through.

[0034] The handle 102 is provided with a plurality of magnetic sheets 10202 to keep the two handles 102 in a fitted state.

[0035] The details of this application are as follows:

[0036] When the user needs to rotate and unfold the two boxes 101, the user can pass his fingers through the through hole 10201 to separate the two handles 102, which is convenient for the user's operation. Furthermore, when the user rotates and closes the two boxes 101, the two handles can be kept in contact with each other through the magnetic sheet 10202, avoiding shaking during use that makes it difficult to align the bolt holes of the two connecting plates 103, causing difficulty in fixing, thereby improving practicality.

[0037] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the purpose of the present invention.
