[0047] Among them, in order to achieve the purpose of installation and disassembly, the present device adopts the following technical solutions: the disassembly component includes a card block 29 and a support block 30, the card block 29 and the support block 30 are fixedly connected to the top of the cabinet 1, a reciprocating screw 2 31 is embedded in the card block 29 and the support block 30, a sliding seat 2 32 is provided on the outside of the reciprocating screw 2 31, the sliding seat 2 32 is connected to the reciprocating screw 2 31 through a ball screw pair, a card block 2 33 is fixedly provided on the outside of the sliding seat 2 32, the card block 2 33 is in sliding contact with the top of the cabinet 1, and the card block 2 33 is in sliding contact with the card block 2 The inner side of the block 1 29 is fixedly connected with a protrusion 34, the reciprocating screw 2 31 is connected with the block 1 29 and the support block 30 through a bearing, and a mounting block 35 is fixedly connected between the block 1 29 and the block 2 33. A card slot is provided on both sides of the mounting block 35, and two protrusions 34 are respectively embedded in the two card slots. The four corners of the top of the mounting block 35 are fixedly connected with mounting frames 36, and four mounting frames 36 are provided with mounting holes. The design of the disassembly assembly can not only facilitate the installation of the device on the distribution box, but also facilitate the removal of the device from the distribution box;

[0048] Among them, in order to achieve the purpose of transmission, the device adopts the following technical solutions: one side of the block 29 is fixedly connected to the motor 37, the output shaft of the motor 37 is fixedly connected to the rotating shaft 38, the bottom end of the rotating shaft 38 passes through the top of the cabinet 1 and is connected to the top of the reciprocating screw 9, the rotating shaft 38 is connected to the reciprocating screw 9 through a one-way bearing, the outer sleeve of the rotating shaft 38 is provided with a bevel gear 39, the bevel gear 39 is connected to the rotating shaft 38 through a one-way bearing, one side of the bevel gear 39 is provided with a bevel gear 2 40 meshingly connected therewith, the bevel gear 2 40 is fixedly connected to one end of the reciprocating screw 2 31, and the design of the motor 37, the rotating shaft 38, the bevel gear 1 39 and the bevel gear 2 40 can make the reciprocating screw 9 and the reciprocating screw 2 31 rotate;

[0049] Among them, in order to achieve the purpose of reducing wear, the present device adopts the following technical solution: the reciprocating screw 9 is connected to the cabinet 1 through a bearing, and the rotating shaft 38 is connected to the cabinet 1 through a bearing. The bearing connection can reduce wear.

[0050] The use process of the present invention is as follows: use bolts to install the mounting frame 36 and the mounting block 35 on the bottom of the low-voltage distribution box, then hold the cabinet 1 so that the right-side protrusion 34 is stuck in the right-side slot, and then control the motor 37 to reverse, and the motor 37 reverses to drive the rotating shaft 1 38 to rotate. Since the reciprocating screw 1 9 is connected to the rotating shaft 1 38 through a one-way bearing, the reciprocating screw 1 9 does not rotate when the motor 37 reverses, and the rotation of the rotating shaft 1 38 drives the bevel gear 1 39 to rotate, and the rotation of the bevel gear 1 39 drives the bevel gear 2 40 to rotate, and the rotation of the bevel gear 2 40 drives the reciprocating screw 2 31 to rotate, and then drives the sliding seat 2 32 to move rightward, and the sliding seat 2 32 moves rightward to make the block 2 33 and the protrusion 34 on the left move rightward, so that the protrusion 34 on the left will be stuck in the slot on the left, so that the device can be installed on the low-voltage distribution box;

[0051] After installation, pass the cable entering the box through the wire trough 2 42 and connect it to the bottom of the cable connector 3, then pass the cable connected to the low-voltage distribution box through the wire trough 1 41 and connect it to the top of the cable connector 3. When connecting, connect the cable in series with the ammeter 4, so that you can observe whether the current in the cable is abnormal in the later stage;

[0052] After the cables are connected, the motor 37 is controlled to rotate forward. Since the bevel gear 39 and the rotating shaft 38 are also connected through a one-way bearing, the bevel gear 39 does not rotate when the motor 37 rotates forward, while the reciprocating screw 9 rotates. At the same time, the two fans 7 are controlled to work so that the cable connector 3 and the ammeter 4 can be blown. At the same time, the rotation of the reciprocating screw 9 can make the sliding seat 10 and the moving block 11 move up and down continuously. Then, under the action of the two ropes 12 and the two springs 8, the moving block 11 moves up and down, which can make the moving plate 6 and the two fans 7 move up and down continuously, so that the wind can be blown evenly on the cable connector 3 and the ammeter 4. At the same time, under the action of the two air-permeable nets 15, the fan 7 can also accelerate the air flow rate inside the cabinet 1 while blowing, so that the hot air inside the cabinet 1 is discharged, so that the inside of the cabinet 1 will be high temperature, and the components will not be damaged by high temperature.

[0053] When the moving block 11 moves up and down, the moving rod 19 and the piston 18 can be continuously moved up and down. Then, under the action of the pipe 1 26, the piston 18 moves up and down to make the air in the box 17 and the box 2 21 flow back and forth. When the air flows back and forth, the piston 22 can be continuously moved up and down, thereby driving the moving rod 2 43, the connecting piece 25 and the moving rod 3 24 to continuously move up and down. The moving rod 3 24 moves up and down to make the cleaning brush 23 continuously move up and down. The cleaning brush 23 moves up and down to clean the dust adhered to the left air permeable net 15, thereby preventing the dust from blocking the mesh of the air permeable net 15, thereby ensuring that the air flows normally through the air permeable net 15 into the cabinet 1, thereby ensuring the heat dissipation effect.

[0054] When the components in the cabinet 1 are damaged, the control motor 37 is reversed again, so that the sliding seat 32 and the clamping block 33 can be moved to the left, so that the protrusion 34 on the left side can be removed from the clamping slot, and then the device can be removed from the low-voltage distribution box, so as to facilitate the maintenance and replacement of the components inside the cabinet 1.

[0055] The above are only preferred embodiments of the present invention. Any person skilled in the art may modify the present invention by using the above technical solutions or modify it into an equivalent technical solution. Therefore, any simple modification or equivalent replacement made according to the technical solution of the present invention belongs to the scope of protection claimed by the present invention.
