[0018] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0019] like Figure 1-4 As shown, a power line protection device proposed in one embodiment of the utility model comprises: a box body 1, a box cover 2 is rotatably mounted on the box body 1 through a hinge, and the box body 1 and one end of the box cover 2 are fixed by a lock;

[0020] There are two vents 3, each of which is constructed on the box cover 2, and each of the two vents 3 is provided with a cooling fan 4;

[0021] A filter cover 5, which is detachably mounted on the top of the box cover 2 and is used to prevent dust from entering the box body 1;

[0022] The mounting frame 6 is detachably mounted on the box cover 2 , and a containing cloth 8 is fixedly mounted on the bottom of the mounting frame 6 for containing dry powder.

[0023] Place the connectors of the two lines in the box body 1, and then close the box cover 2. The combination of the box body 1 and the box cover 2 is used to protect the connection of the lines to avoid external damage. When the temperature in the box body 1 is too high, the two cooling fans 4 can be started for rapid heat dissipation. The filter cover 5 arranged on the top can block the dust in the air without affecting its heat dissipation. At the same time, the bottom of the box body 1 is provided with cooling fins 14, which improves the heat dissipation effect inside the box body 1 and avoids the problem of damage to the line connector due to long-term high temperature environment, thereby greatly improving the service life of the line. When a short circuit occurs at the line connector and burns, since the cloth 8 is a very thin layer of cloth, it will burn quickly after touching the flame, and then the dry powder placed on it will fall, quickly cover and extinguish the generated flame, so that the connector stops burning, avoiding the spread of fire, and greatly improving the protection performance of this equipment.

[0024] Therefore, compared with the prior art, the utility model uses the cooling fan 4 to quickly dissipate heat, and the filter cover 5 arranged on the top thereof can block dust in the air without affecting the heat dissipation. At the same time, the bottom of the box body 1 is provided with cooling fins 14, which improves the heat dissipation effect inside the box body 1, avoids the problem of damage caused by the line connector being in a high temperature environment for a long time, thereby greatly improving the service life of the line. When a short circuit occurs at the line connector, the dry powder contained in the containing cloth 8 can be used to quickly cover and extinguish the flame generated by the line combustion, so that the connection head stops burning, avoiding the spread of the fire, and greatly improving the protection performance of the device.

[0025] like Figure 1 As shown, in some embodiments, connecting plates 9 are fixedly installed on both sides of the filter cover 5, and the connecting plates 9 are fixedly connected to the box cover 2 by bolts.

[0026] The setting of the bolts facilitates the installation and disassembly of the filter cover 5. The filter cover 5 that has been used for a long time can be disassembled for cleaning, so that the bolts can be rotated to release the fixation of the connecting plate 9 and the box cover 2, and then the fixation of the filter cover 5 can be released. The operation is simple and convenient.

[0027] like Figure 2 and Figure 4 As shown, in some embodiments, a T-shaped plate 10 is fixedly installed on the top of the installation frame 6, a T-shaped slot is configured on the box cover 2, and the T-shaped plate 10 is inserted into the T-shaped slot, a positioning plate 11 is fixedly installed on one side of the installation frame 6, and a fixing assembly 12 for fixing the positioning plate 11 is installed on the box cover 2. The fixing assembly 12 includes two half-short rods 121 fixedly installed on one side of the box cover 2 and the positioning plate 11, respectively, and the two half-short rods 121 are both provided with threads, and one end of the two half-short rods 121 is threadedly sleeved with a threaded barrel 122.

[0028] The installation frame 6 is suspended on the box cover 2 through the T-plate 10, and the T-plate 10 is inserted in the T-slot, which is convenient for installation and disassembly. The threaded cylinder 122 is rotated to release the threaded fixation with the two half short rods 121, and the positioning plate 11 is pulled to pull the installation frame 6 out of the box cover 2, and then dry powder or some fire-extinguishing materials are put in and then installed. The operation is simple and convenient for people to use.

[0029] like Figure 2 As shown, in some embodiments, a through opening is constructed between the box body 1 and the box cover 2, and a protective pad 13 is fixedly installed on the inner wall of the through opening.

[0030] The line passes through the through opening, and the protective pad 13 on the inner wall of the through opening is used to protect the line from being scratched. At the same time, the through opening is closed to prevent dust or other dirt from entering. The protective pad 13 has a certain friction force, which makes it difficult for the line to be pulled at will.

[0031] like Figure 2 As shown, in some embodiments, a plurality of heat dissipation fins 14 are fixedly installed on the top of the box body 1 in a linear array, and the heat dissipation fins 14 are S-shaped.

[0032] The heat generated by the line connection port is dissipated in the box body 1, and the box body 1 absorbs the heat and conducts the heat to the heat dissipation fins 14 by means of heat conduction. The heat dissipation fins 14 contact the air to dissipate the heat, thereby improving the heat dissipation effect. At the same time, the heat dissipation fins 14 are S-shaped, with a larger contact area with the air and a better heat dissipation effect. The heat dissipation fins 14 support the box body 1, so that the bottom of the box body 1 contacts the air, thereby improving the heat dissipation effect.

[0033] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
