[0009] Preferably, both the busbar compartment and the cable compartment have equally spaced threading adhesive holes at their bottom interiors, and both cable compartments have a sealing cover mounted on the side of each threading adhesive hole via a hinge.

[0010] Preferably, a power cord is placed on one side of the busbar compartment, an energized plug is installed inside the busbar compartment, a slide rail is provided on the upper surface of the side of the cabinet, and there are two slide rails. A slide block is slidably installed on the outside of the slide rail, an electrical box is provided on the upper surface of the slide block, and an energized plug is installed on one side of the electrical box.

[0011] Preferably, a second slide groove is provided on the upper surface of the side of the cabinet and at the middle position of the two slide rails facing each other. A second slider is installed at the middle position of the bottom end of the slide of the electrical box and inside the second slide groove. A crank is rotatably installed on the side of the cabinet, and the crank is threadedly connected to the second slider.

[0012] Preferably, a knob shaft is installed on both sides of the cabinet, a swing rod is provided on the outside of the two knob shafts, a rain shield is provided inside the two swing rods, and a limit stop is provided on both sides of the cabinet and on one side of the knob shaft.

[0013] Preferably, a first cooperating swing rod is provided on both sides of the cabinet, and a second cooperating swing rod is rotatably installed on the other side of each of the two first cooperating swing rods. An adjustment groove is provided inside each of the two second cooperating swing rods, and a screw is installed inside the adjustment groove and connected to the swing rod.

[0014] A method of using a switch cabinet with a dustproof detection structure includes the following steps:

[0015] S1: When more than a set number of electrical appliances need to be installed inside the control room, rotate the hexagonal threaded lever to slide the electrical appliance mounting plate installed inside the control room out. Install each electrical appliance using two mounting plates inside the control room. After the electrical appliances are installed, connect the power cord to the appliances. The other end of the power cord is located inside the busbar compartment. Thread the other end of the power cord to the power-on terminal block. When cables need to be installed, insert the cable into the cabinet through the cable guide hole at the bottom of the cabinet. When cables are not needed, close the sealing cover to seal the inside of the cabinet. When power needs to be supplied after the electrical appliances are installed inside the cabinet, rotate the crank lever at the rear of the cabinet. Through the threaded connection between the crank lever and the second slider, the electrical box slides to the rear of the busbar compartment. Continue rotating the crank lever until the power-on terminal on the side of the electrical box is inserted into the power-on terminal block installed inside the busbar compartment, supplying power to the inside of the cabinet through the electrical box.

[0016] S2: When the cabinet is working, the temperature inside the cabinet is observed by the temperature gauge installed on the front surface of the heat dissipation and dustproof box. When the temperature of the electrical appliances rises, the cylinder is activated. After the cylinder is activated, its output shaft drives the connecting plate installed inside the heat dissipation and dustproof box to slide. The sliding of the connecting plate will drive the two positioning ring seats to slide. The sliding of the two positioning ring seats will drive the entire support rod to rise. During the rise of the support rod, the fan installed above it will dissipate heat from the electrical appliances inside the cabinet. When the dust inside the cabinet exceeds the set value, the reverse fan will blow out the dust inside the cabinet.

[0017] S3: In rainy weather, rotating the knob shaft drives the swing arm to rotate, adjusting the tilt angle of the rain shield and setting up rain protection for the cabinet. During the rotation of the swing arm, the swing arm is fixed and then reinforced by the cooperation between the first and second cooperating swing arms.

[0018] Compared with related technologies, the switch cabinet with a dustproof detection structure and its usage method provided by the present invention have the following beneficial effects:

[0019] If a large number of electrical appliances need to be installed inside the control room, rotating the hexagonal threaded rod will allow the electrical mounting plates installed inside the control room to slide out. This allows users to easily install electrical appliances by adjusting the internal space of the control room. In case of danger to the cabinet, simply rotating the insulated crank rod will move the electrical box inside the cabinet for power outage maintenance.

[0020] When the cabinet is in operation, the internal temperature is monitored by a thermometer installed on the front surface of the heat dissipation and dustproof box. When the temperature of the electrical components rises, the cylinder is activated. After the cylinder is activated, its output shaft drives the connecting plate installed inside the heat dissipation and dustproof box to slide. The sliding of the connecting plate drives the two positioning ring seats to slide. The sliding of the two positioning ring seats drives the entire support rod to rise. During the rise of the support rod, the fan installed above it dissipates heat from the electrical components inside the cabinet. The fan, driven by the cylinder, moves the support rod up and down, which can dissipate heat from multiple locations inside the cabinet. If there is dust inside the cabinet, the fan can be reversed to blow the dust out.

[0021] In rainy weather, turning the knob shaft will cause the swing arm to rotate, which can adjust the tilt angle of the rain shield to facilitate rain protection for the cabinet. During the rotation of the swing arm, the cooperation between the first and second cooperating swing arms can provide secondary reinforcement after the swing arm is fixed.

The power-on plug 14 is connected to the power-on plug 40 of the electrical box 17, and the electrical box 17 supplies power to the entire electrical appliance.

[0036] A second slide groove 37 is provided on the upper surface of the side of the cabinet 1, in the middle of the two slide rails 16 facing each other. A second slider 38 is installed in the middle of the bottom of the slide base 18 of the electrical box 17, inside the second slide groove 37. A crank handle 19 is rotatably installed on the side of the cabinet 1, and the crank handle 19 and the second slider 38 are threaded together. In case of danger to the cabinet 1, the electrical box 17 can be moved into the cabinet 1 by simply rotating the insulated crank handle 19, so that the cabinet 1 can be powered off and repaired.

[0037] Both sides of the cabinet 1 are equipped with knob shafts 20, and swing rods 21 are fixed to the outside of the two knob shafts 20. Rain shields 22 are fixed inside the two swing rods 21. Limit blocks 23 are fixed on both sides of the cabinet 1 and on one side of the knob shafts 20.

[0038] Both sides of the cabinet 1 are fixed with first cooperating swing rods 24, and the other side of each of the two first cooperating swing rods 24 is rotatably installed with a second cooperating swing rod 25. Each of the two second cooperating swing rods 25 has an adjustment slot 26 inside, and a screw is installed inside the adjustment slot 26. The screw is fixedly connected to the swing rod 21. During the rotation of the swing rod 21, the swing rod 21 can be fixed and then reinforced by the cooperation between the first cooperating swing rod 24 and the second cooperating swing rod 25.

[0039] Correspondingly, a method for using a switchgear with a dustproof detection structure includes the following steps:

[0040] S1: When a large number of electrical appliances (the number can be set by the user) need to be installed inside the control room 2, rotate the hexagonal threaded rod 9 to slide the electrical mounting plate 7 installed inside the control room 2 out. By installing two electrical mounting plates 7 inside the control room 2, it is convenient for users to install each electrical appliance. After the electrical appliances are installed, connect the power cord 15 to the electrical appliances. The other side of the power cord 15 is located inside the busbar compartment 3. Then, connect the other side of the power cord 15 to the power plug 14. When it is necessary to install cables, put the cables into the cabinet 1 from the bottom of the cabinet 1 through the cable insertion hole 13. When cables are not needed, the sealing cover 36 can be put down to seal the inside of the cabinet 1. When the electrical appliances inside the cabinet 1 are installed and power is needed, turn the crank handle 19 at the rear of the cabinet 1. Through the threaded connection between the crank handle 19 and the second slider 38, the electrical box 17 can be moved horizontally to the rear of the busbar compartment 3. Keep turning the crank handle 19 until the power supply post 40 (i.e. plug) on ​​the side of the electrical box 17 is inserted into the power supply plug 14 installed inside the busbar compartment 3, and then power can be supplied to the inside of the cabinet 1 through the electrical box 17.

[0041] S2: When the cabinet 1 is working, the temperature inside the cabinet 1 is observed by the temperature gauge 39 installed on the front surface of the heat dissipation and dustproof box 27. When the temperature of the electrical appliances rises, the cylinder 28 is activated. After the cylinder 28 is activated, its output shaft will drive the connecting plate 32 installed inside the heat dissipation and dustproof box 27 to slide. The sliding of the connecting plate 32 will drive the two positioning ring seats 30 to slide. The sliding of the two positioning ring seats 30 will drive the entire support rod 31 to rise. During the rise of the support rod 31, the fan 35 installed above it will dissipate heat from the electrical appliances inside the cabinet 1. When there is a lot of dust inside the cabinet 1, the reverse fan 35 can blow the dust out of the cabinet 1.

[0042] S3: In rainy weather, turn the knob shaft 20. The rotation of the knob shaft 20 will drive the swing rod 21 to rotate. The rotation of the swing rod 21 can adjust the tilt angle of the rain shield 22, which is convenient for setting up rain protection for the cabinet 1. During the rotation of the swing rod 21, the first cooperating swing rod 24 and the second cooperating swing rod 25 can fix the swing rod 21 and provide secondary reinforcement.

[0043] When multiple electrical appliances need to be installed inside the control room 2, the hexagonal threaded rod 9 is rotated to allow the electrical appliance mounting plates 7 installed inside the control room 2 to slide out. Two electrical appliance mounting plates 7 are installed inside the control room 2 to facilitate the installation of multiple electrical appliances. After the electrical appliances are installed, the power cord 15 is connected to them. The other side of the power cord 15 is inside the busbar compartment 3. The other side of the power cord 15 is then threaded into the power connector 14. When cables need to be installed, they are inserted from the bottom of the cabinet 1 through the cable threading hole 13 into the interior of the cabinet 1. When no cable is needed, the sealing cover 36 can be closed to seal the inside of the cabinet 1. After the electrical appliances inside the cabinet 1 are installed, when power needs to be supplied, the crank handle 19 at the rear of the cabinet 1 is rotated. Through the threaded connection between the crank handle 19 and the second slider 38, the electrical box 17 can be moved horizontally to the rear of the busbar compartment 3. A power supply post 40 is installed on one side of the electrical box 17. The crank handle 19 is rotated until the power supply post 40 on the side of the electrical box 17 is inserted into the power supply plug 14 installed inside the busbar compartment 3, and then power can be supplied to the inside of the cabinet 1 through the electrical box 17.

[0044] When cabinet 1 is in operation, the temperature inside cabinet 1 is monitored by a thermometer 39 installed on the front surface of the heat dissipation and dustproof box 27. When the temperature of the electrical appliances rises, cylinder 28 is activated. After cylinder 28 is activated, its output shaft will drive the connecting plate 32 installed inside the heat dissipation and dustproof box 27 to slide. The sliding of the connecting plate 32 will drive the two positioning ring seats 30 to slide. The sliding of the two positioning ring seats 30 will drive the entire support rod 31 to rise. During the rise of the support rod 31, the fan 35 installed above it will dissipate heat from the electrical appliances inside cabinet 1. When there is a lot of dust inside cabinet 1, the fan 35 can be reversed to blow the dust out of cabinet 1. In rainy weather, the knob shaft 20 is turned. The rotation of the knob shaft 20 will drive the swing rod 21 to rotate. The rotation of the swing rod 21 can adjust the tilt angle of the rain shield 22 to facilitate rain protection for cabinet 1. During the rotation of the swing rod 21, the first cooperating swing rod 24 and the second cooperating swing rod 25 can fix the swing rod 21 and provide secondary reinforcement.

[0045] Compared with related technologies, the switch cabinet with a dustproof detection structure and its usage method provided by the present invention have the following beneficial effects:

[0046] If a large number of electrical appliances need to be installed inside the control room 2, the hexagonal threaded rod 9 can be rotated to allow the electrical appliance mounting plate 7 installed inside the control room 2 to slide out. By adjusting the internal space of the control room 2, it is convenient for users to install electrical appliances.

[0047] When the cabinet 1 is working, the temperature inside the cabinet 1 is observed by the temperature gauge 39 installed on the front surface of the heat dissipation and dustproof box 27. When the temperature of the electrical appliances rises, the cylinder 28 is activated. After the cylinder 28 is activated, its output shaft will drive the connecting plate 32 installed inside the heat dissipation and dustproof box 27 to slide. The sliding of the connecting plate 32 will drive the two positioning ring seats 30 to slide. The sliding of the two positioning ring seats 30 will drive the entire support rod 31 to rise. During the rise of the support rod 31, the fan 35 installed above it will dissipate heat from the electrical appliances inside the cabinet 1. When there is a lot of dust inside the cabinet 1, the fan 35 can be reversed to blow the dust out of the cabinet 1.

[0048] In rainy weather, turning the knob shaft 20 will cause the swing rod 21 to rotate. The rotation of the swing rod 21 can adjust the tilt angle of the rain shield 22, which is convenient for rain protection of the cabinet 1. During the rotation of the swing rod 21, the first cooperating swing rod 24 and the second cooperating swing rod 25 can fix the swing rod 21 and provide secondary reinforcement.
