Description

Technical Field

[0001] The invention relates to the technical field of power distribution cabinets, and in particular to an energy-saving and environment-friendly high and low voltage power distribution cabinet. Background Art

[0002] High and low voltage distribution cabinets are important equipment in the power system, used to distribute and control electricity. They are mainly used for power access, distribution, protection and control to ensure the safe operation of electrical equipment.

[0003] When the existing distribution cabinet is in use, the cabinet door can protect the internal electrical equipment from dust, moisture and physical damage. The cabinet door and the cabinet body are connected together by hinges. When opening the cabinet door, it needs to be opened horizontally. However, sometimes due to the small installation location, the cabinet door that opens horizontally is easily hit, resulting in damage to the cabinet body. At the same time, it is not very convenient to remove the cabinet door connected by the hinge from the distribution cabinet. In addition, when using the distribution cabinet, a heat sink is installed on the cabinet body, and the hot air inside the cabinet is discharged through the slots on the heat sink to dissipate the heat inside the cabinet. However, sometimes the internal temperature is too high and the heat dissipation speed of the heat sink is slow, resulting in the internal components of the distribution cabinet being burned out due to excessive temperature. At the same time, when the electrical components inside the distribution cabinet are installed, they are installed by means of clips or screws. Some distribution cabinets have a small internal space. When replacing electrical components, the clips or screws are not convenient for personnel to replace the components. Summary of the invention

[0004] The present invention provides an energy-saving and environment-friendly high and low voltage distribution cabinet. When the distribution cabinet is in use, the cabinet door can be easily removed from the distribution cabinet, which is convenient for personnel to repair and replace the inside of the distribution cabinet. At the same time, it also reduces the risk of collision that may occur when the cabinet door is opened horizontally on the existing distribution cabinet, and the cabinet door has a relatively good protective effect to prevent accidental collision and deformation, which affects the use. When the distribution cabinet is in use, the heat dissipation speed of the cabinet body is fast and the heat dissipation effect is also good, which can prevent the internal temperature from being too high and causing the internal components to burn out. When electrical components are installed inside the distribution cabinet, the installation method of the electrical components is simple, which improves the replacement speed of the components and further improves the practicality of the distribution cabinet.

[0005] In order to achieve the above object, the present invention adopts the following technical scheme: an energy-saving and environmentally friendly high and low voltage distribution cabinet, the distribution cabinet comprising:

The support rod enables the drive motor to be installed inside the cabinet, and when the external power switch of the drive motor is turned on, its output shaft drives the first rotating rod to rotate.

[0015] As a further improvement scheme of the present invention: a second rotating rod is arranged on one side of the inner wall of the cabinet through a bearing, and pulleys are fixedly sleeved on the outer surfaces of the first rotating rod and the second rotating rod, and belts are movably sleeved on the outer surfaces of the two pulleys, and fan blades are installed on one end of the first rotating rod and the second rotating rod, and the second rotating rod is connected to the cabinet through a bearing, and the second rotating rod can rotate, and the rotation of one of the pulleys causes the other pulley to rotate through the belt, and further causes the first rotating rod and the second rotating rod to rotate in the same direction, and the rotation of the two fan blades causes the surrounding air to flow, thereby generating a negative pressure area, which attracts the air inside the cabinet through the notch on the slot plate, and then discharges it through the two heat dissipation plates.

[0016] As a further improvement scheme of the present invention: a groove plate is fixedly provided on the inner wall of the cabinet, and heat dissipation plates are installed on both sides of the cabinet, and two L-shaped rods are fixedly provided on the outer surface of one of the slides, and a cleaning brush is fixedly provided at one end of the two L-shaped rods. The gas inside the cabinet is discharged through the grooves on the two heat dissipation plates, and the protective plate is pressed to make one of the slides slide on the outer surface of the vertical rod, and the two cleaning brushes are further driven to move through the two L-shaped rods. The side of the two cleaning brushes with bristles is tightly attached to the side of the two heat dissipation plates. When the two cleaning brushes move back and forth, they will scrape the dust accumulated on the two heat dissipation plates to prevent the dust from affecting the heat dissipation effect of the cabinet.

[0017] As a further improvement of the present invention: two protective frames are fixedly provided on the inner wall of the bottom of the cabinet, and a bidirectional screw rod is provided on the inner wall of one of the protective frames through a bearing. The bidirectional screw rod can rotate due to the bearing, and the outer surface of the bidirectional screw rod has two thread grooves with different rotation directions.

[0018] As a further improvement scheme of the present invention: the outer surface thread sleeve of the bidirectional screw rod is provided with two threaded barrels, the outer surfaces of the two threaded barrels are fixedly provided with cross plates, and one side of the two cross plates is fixedly provided with clamping plates, the two threaded barrels and the two threaded grooves with different rotation directions on the outer surface of the bidirectional screw rod are connected together, when the bidirectional screw rod rotates in different directions, the two threaded barrels do not rotate together, and the two threaded barrels make relative or opposite movements on the outer surface of the bidirectional screw rod.

[0019] As a further improvement scheme of the present invention: another round rod is fixedly provided on the inner wall of the protective frame, and two sleeves are movably sleeved on the outer surface of the round rod, and the two sleeves are respectively fixed on one side of the two horizontal plates, and the two threaded tubes are connected together through the two horizontal plates and the two sleeves. The two sleeves can slide on the outer surface of the round rod, and then when the bidirectional screw rotates in different directions, the two threaded tubes move relative to or oppositely on the outer surface of the bidirectional screw.

[0020] As a further improvement scheme of the present invention: a turntable is fixedly provided on one side of the bidirectional screw rod, and a mounting plate is fixedly provided on one side of the cabinet body. The turntable facilitates the rotation of the bidirectional screw rod. The turntable is arranged outside the cabinet body, and personnel do not need to reach into the interior of the cabinet body for operation, thereby improving the replacement speed of components. Threaded holes are opened on the mounting plate, and the cabinet body can be installed at the use location through the mounting plate.

[0021] As a further improvement scheme of the present invention: extrusion springs are fixedly arranged on the opposite sides of the two slide cylinders, and positioning grooves are opened on both sides of the slide rails. The two extrusion springs will generate a reverse force when squeezed, which will reduce part of the force exerted on the protection plate, further reduce the force exerted on the cabinet door, and improve the protective effect of the cabinet door. The two positioning grooves are matched with the two fixed blocks. When the two fixed blocks are on one side of the two positioning grooves, the elastic force generated by the two reset springs pushes the two second telescopic rods, so that the two fixed blocks slide out of the inside of the two grooves, further fixing the position of the cabinet door.

[0022] Compared with the prior art, the advantages and positive effects of the present invention are:

[0023] 1. In the present invention, when the power distribution cabinet is in use, the cabinet door can slide on the inner wall of the slide rail, and the two second telescopic rods can move on the outer surfaces of the two first telescopic rods respectively. At this time, the two fixing blocks are pushed respectively, so that the two second telescopic rods slide to the outer surfaces of the two first telescopic rods and the two return springs are squeezed respectively. At this time, the two fixing blocks slide into the interior of the groove, and the two fixing blocks are not stuck on the inner walls of the two positioning grooves. By sliding the cabinet door, it is removed from the cabinet body, and the internal structure of the cabinet body can be repaired and processed. When the cabinet door is covered, the two sides of the cabinet door are at the inner wall of the slide rail. At this time, when the cabinet door is sliding, when the two fixing blocks are on one side of the two positioning grooves, the elastic force generated by the two return springs pushes the two second telescopic rods, so that the two fixing blocks slide out of the interior of the two grooves, further fixing the position of the cabinet door. At the same time, when the cabinet door is In case of an accidental collision, the protection plate prevents the cabinet door from contacting the stress point. At the same time, the pressure on the protection plate is transmitted to the bottom rod. The two transmission rods can rotate around the two second connecting shafts or the two first connecting shafts, and the two slides can slide on the outer surface of the vertical rod. At this time, the force received by the bottom rod causes the two transmission rods to push the two slides, which further cause the two slides and the two connecting plates to squeeze the two extrusion springs. The two extrusion springs will generate a reverse force when squeezed, which will reduce part of the force received by the protection plate and further reduce the force received by the cabinet door. Therefore, when using the distribution cabinet, the cabinet door is easy to remove from the distribution cabinet, which is convenient for personnel to repair and replace the inside of the cabinet. At the same time, it also reduces the risk of collision that may occur when the cabinet door on the existing distribution cabinet is opened horizontally, and the protective function of the cabinet door is also relatively good to prevent deformation caused by accidental collision and affect use.

[0024] 2. The present invention, when using the power distribution cabinet, dissipates heat inside the cabinet through two heat sinks. When the temperature inside the cabinet is high, the external power switch of the driving motor is turned on, and the supporting rod allows the driving motor to be installed inside the cabinet, so that the output shaft of the driving motor drives the first rotating rod to rotate, and further causes one of the pulleys to rotate. Since the second rotating rod is connected to the cabinet through a bearing, the second rotating rod can rotate, and the two pulleys are connected through a belt, so that when the first rotating rod rotates, the second rotating rod is driven to rotate in the same direction, and further causes the two fan blades to rotate in the same direction. The rotation of the two fan blades causes the surrounding air to flow, and a negative pressure area is generated. The air inside the cabinet is attracted through the notches on the slot plate and then discharged through the two heat sinks, thereby reducing the internal temperature of the cabinet more quickly. When the two heat sinks are used for too long, one of the slides is pressed on the outer surface of the vertical pole by pressing the protective plate, and the two cleaning brushes are further driven to move by the two L-shaped rods. The bristle side of the two cleaning brushes is in close contact with the side of the two heat sinks. When the two cleaning brushes move back and forth, they will scrape away the dust accumulated on the two heat sinks to prevent the dust from affecting the heat dissipation effect of the cabinet. Therefore, when the power distribution cabinet is used, the cabinet has a fast heat dissipation speed and a good heat dissipation effect, which can prevent the internal temperature from being too high and causing internal components to burn out.

[0025] 3. According to the present invention, when installing electrical components inside the distribution cabinet, the electrical components are placed on the upper side of one of the clamping plates. At this time, the two-way screw rod is driven to rotate by rotating the turntable clockwise. Since the two threaded barrels and the two threaded grooves of different rotation directions on the outer surfaces of the two-way screw rod are connected together, and the two threaded barrels are connected together by two cross plates and two sleeves, the two sleeves can slide on the outer surface of the round rod, and then when the two-way screw rod rotates in different directions, the two threaded barrels move relative to or oppositely on the outer surface of the two-way screw rod. At this time, the two-way screw rod rotates clockwise, so that the two threaded barrels move toward each other, and further the two clamping plates move toward each other through the two cross plates. When the turntable cannot rotate, the two clamping plates clamp the electrical components to complete the installation thereof. The cabinet body can be installed at the use location through the mounting plate, so that when the electrical components are installed inside the distribution cabinet, the installation method of the electrical components is simple, the replacement speed of the components is improved, and the practicality of the distribution cabinet is further improved. The shaping and finalization of plastic bottles is convenient and simple, which is convenient for users to operate and improves the processing efficiency of plastic bottles.

[0042] When in use, the cabinet door 201 can slide on the inner wall of the slide rail 2, and the two second telescopic rods 204 can move on the outer surfaces of the two first telescopic rods 203 respectively. At this time, the two fixing blocks 205 are pushed respectively, so that the two second telescopic rods 204 slide to the outer surfaces of the two first telescopic rods 203, and the two return springs 206 are squeezed respectively. At this time, the two fixing blocks 205 slide into the interior of the groove 202, and the two fixing blocks 205 are not stuck on the inner walls of the two positioning grooves 216. By sliding the cabinet door 201, it is removed from the cabinet body 1, and the internal structure of the cabinet body 1 can be repaired and processed. When the cabinet door 201 is covered, the two sides of the cabinet door 201 are located at the inner walls of the slide rail 2. At this time, when the cabinet door 201 is sliding, when the two fixing blocks 205 are on one side of the two positioning grooves 216, the elastic force generated by the two return springs 206 pushes the two second The telescopic rod 204 allows the two fixing blocks 205 to slide out of the two grooves 202, further fixing the position of the cabinet door 201.

The second rotating rod 304 is connected to the cabinet 1 through a bearing, and the second rotating rod 304 can rotate. The rotation of one of the pulleys 305 causes the other pulley 305 to rotate through the belt 307, and further causes the first rotating rod 303 and the second rotating rod 304 to rotate in the same direction. The rotation of the two fan blades 306 causes the surrounding air to flow, generating a negative pressure area, and attracting the air inside the cabinet 1 through the notch on the slot plate 3, and then discharged through the two heat dissipation plates 308.

[0045] See also Figures 1 to 10 In one embodiment, a groove plate 3 is fixedly provided on the inner wall of the cabinet 1, and heat sinks 308 are installed on both sides of the cabinet 1.

The internal gas of the cabinet 1 is discharged through the grooves on the two heat sinks 308. The protective plate 215 is pressed to make one of the slides 209 slide on the outer surface of the vertical rod 208, and the two cleaning brushes 310 are further driven to move through the two L-shaped rods 309. The side of the two cleaning brushes 310 with bristles is tightly attached to the side of the two heat sinks 308. When the two cleaning brushes 310 move back and forth, they will scrape the dust accumulated on the two heat sinks 308 to prevent the dust from affecting the heat dissipation effect of the cabinet 1.

[0046] See also Figures 1 to 10 In one embodiment, two protective frames 4 are fixedly provided on the inner wall of the bottom of the cabinet 1, and a bidirectional screw rod 401 is provided on the inner wall of one of the protective frames 4 through a bearing. The bidirectional screw rod 401 can rotate due to the bearing, and the outer surface of the bidirectional screw rod 401 has two thread grooves with different rotation directions.

[0047] See also Figures 1 to 10 In one embodiment, the outer surface of the bidirectional screw rod 401 is threadedly sleeved with two threaded barrels 402, and the outer surfaces of the two threaded barrels 402 are fixedly provided with a horizontal plate 405, and one side of the two horizontal plates 405 is fixedly provided with a clamping plate 406. The two threaded barrels 402 and the two threaded grooves with different rotation directions on the outer surfaces of the bidirectional screw rod 401 are connected together. When the bidirectional screw rod 401 rotates in different directions, the two threaded barrels 402 do not rotate together, and the two threaded barrels 402 move relative to or oppositely on the outer surface of the bidirectional screw rod 401.

[0048] See also Figures 1 to 10In one embodiment, a round rod 403 is fixedly provided on the inner wall of another protective frame 4, and two sleeves 404 are movably sleeved on the outer surface of the round rod 403. The two sleeves 404 are respectively fixed on one side of two horizontal plates 405, and the two threaded tubes 402 are connected together through the two horizontal plates 405 and the two sleeves 404. The two sleeves 404 can slide on the outer surface of the round rod 403, and then when the bidirectional screw rod 401 rotates in different directions, the two threaded tubes 402 move relative to or oppositely on the outer surface of the bidirectional screw rod 401.

[0049] See also Figures 1 to 10 In one embodiment, a turntable 407 is fixedly provided on one side of the bidirectional screw rod 401, and a mounting plate 408 is fixedly provided on one side of the cabinet 1. The turntable 407 facilitates the rotation of the bidirectional screw rod 401. The turntable 407 is arranged outside the cabinet 1, and a person does not need to put his hand into the interior of the cabinet 1 for operation, thereby improving the replacement speed of components. A threaded hole is opened on the mounting plate 408, and the cabinet 1 can be installed at the place of use through the mounting plate 408.

[0050] See also Figures 1 to 10 In one embodiment, an extrusion spring 210 is fixedly provided on the opposite side of the two slides 209, and a positioning groove 216 is provided on both sides of the slide rail 2. The two extrusion springs 210 will generate a reverse force when squeezed, which will reduce a part of the force exerted on the protection plate 215, further reduce the force exerted on the cabinet door 201, and improve the protective effect of the cabinet door 201. The two positioning grooves 216 match the two fixed blocks 205. When the two fixed blocks 205 are on one side of the two positioning grooves 216, the elastic force generated by the two return springs 206 pushes the two second telescopic rods 204, so that the two fixed blocks 205 slide out of the two grooves 202, further fixing the position of the cabinet door 201.

[0051] Working principle: When the power distribution cabinet is in use, the cabinet door 201 can slide on the inner wall of the slide rail 2, and the two second telescopic rods 204 can move on the outer surfaces of the two first telescopic rods 203 respectively. At this time, the two fixing blocks 205 are pushed respectively, so that the two second telescopic rods 204 slide to the outer surfaces of the two first telescopic rods 203, and the two return springs 206 are squeezed respectively. At this time, the two fixing blocks 205 slide into the interior of the groove 202, and the two fixing blocks 205 are not stuck on the inner walls of the two positioning grooves 216. The cabinet door 201 is removed from the cabinet body 1 by sliding it, and the internal structure of the cabinet body 1 can be repaired and processed. When the cabinet door 201 is covered, the two sides of the cabinet door 201 are located at the inner wall of the slide rail 2. At this time, when the cabinet door 201 is slid, the two fixing blocks 205 are located on one side of the two positioning grooves 216, and the elastic force generated by the two return springs 206 pushes the two second telescopic rods 204, so that the two fixing blocks 205 slide out of the two grooves 202, further fixing the position of the cabinet door 201. At the same time, when the cabinet door 2 When the cabinet door 201 is hit by an accidental collision, the protection plate 215 prevents the cabinet door 201 from contacting the stress point. At the same time, the pressure on the protection plate 215 is transmitted to the bottom rod 214. The two transmission rods 212 can rotate around the two second connecting shafts 213 or the two first connecting shafts 211, and the two slide cylinders 209 can slide on the outer surface of the vertical rod 208. At this time, the force on the bottom rod 214 causes the two transmission rods 212 to push the two slide cylinders 209, which further causes the two slide cylinders 209 and the two connecting plates 207 to squeeze the two springs. 210 is squeezed, and the two squeezing springs 210 will generate a reverse force when being squeezed, which will reduce a part of the force on the protection plate 215, and further reduce the force on the cabinet door 201, so that when the power distribution cabinet is used, the cabinet door 201 is easy to be removed from the top of the power distribution cabinet, which is convenient for personnel to repair and replace the inside of the cabinet body 1, and at the same time, it also reduces the collision risk that may occur when the cabinet door 201 on the existing power distribution cabinet is opened horizontally, and the protective effect of the cabinet door 201 is also better, preventing accidental collision from causing deformation and affecting use;

[0052] When the power distribution cabinet is in use, the inside of the cabinet 1 is cooled by two heat sinks 308. When the temperature inside the cabinet 1 is high, the external power switch of the drive motor 302 is turned on, and the support rod 301 allows the drive motor 302 to be installed inside the cabinet 1, so that the output shaft of the drive motor 302 drives the first rotating rod 303 to rotate, and further rotates one of the pulleys 305. Since the second rotating rod 304 is connected to the cabinet 1 through a bearing, the second rotating rod 304 can rotate, and the two pulleys 305 are connected together through a belt 307, so that when the first rotating rod 303 rotates, the second rotating rod 304 is driven to rotate in the same direction, and further the two fan blades 306 rotate in the same direction. The rotation of the two fan blades 306 causes the surrounding air to flow, generating negative pressure The air inside the cabinet 1 is drawn through the notch on the slot plate 3 and then discharged through the two heat sinks 308, so as to reduce the internal temperature of the cabinet 1 more quickly. When the two heat sinks 308 are used for too long, the protective plate 215 is pressed to make one of the slides 209 slide on the outer surface of the vertical rod 208, and the two cleaning brushes 310 are further driven to move through the two L-shaped rods 309. The side of the two cleaning brushes 310 with bristles is closely attached to the side of the two heat sinks 308. When the two cleaning brushes 310 move back and forth, the dust accumulated on the two heat sinks 308 is scraped to prevent the dust from affecting the heat dissipation effect of the cabinet 1. Therefore, when the power distribution cabinet is used, the heat dissipation speed of the cabinet 1 is fast and the heat dissipation effect is also good, which can prevent the internal temperature from being too high and causing the internal components to burn out.

[0053] When installing electrical components inside the power distribution cabinet, the electrical components are placed on the upper side of one of the clamping plates 406. At this time, the two-way screw rod 401 is driven to rotate by rotating the turntable 407 clockwise. Since the two threaded barrels 402 and the two threaded grooves with different rotation directions on the outer surfaces of the two-way screw rod 401 are connected together, and the two threaded barrels 402 are connected together by two cross plates 405 and two sleeves 404, the two sleeves 404 can slide on the outer surface of the round rod 403, and then when the two-way screw rod 401 rotates in different directions, the two threaded barrels 402 are in the two-way screw rod. The outer surface of 401 moves relative to or oppositely. At this time, the bidirectional screw rod 401 rotates clockwise, so that the two threaded tubes 402 move toward each other, and further the two clamping plates 406 move toward each other through the two cross plates 405. When the turntable 407 cannot rotate, the two clamping plates 406 clamp the electrical components to complete their installation. The cabinet body 1 can be installed at the place of use through the mounting plate 408. Therefore, when the electrical components are installed inside the distribution cabinet, the installation method of the electrical components is simple, the replacement speed of the components is improved, and the practicality of the distribution cabinet is further improved.
