Description

Technical Field

[0001] This invention belongs to the field of switchgear technology, and particularly relates to an energy-optimized intelligent sensor network-connected low-voltage switchgear. Background Technology

[0002] Low-voltage switchgear, as the core equipment for power distribution, control, and protection in power systems, is widely used in industrial plants, commercial buildings, and residential power distribution. Its operational stability and energy efficiency directly affect the power supply reliability and energy utilization efficiency of the power system. With the in-depth development of smart grid technology, low-voltage switchgear is gradually evolving towards sensing, networking, and energy saving. However, the increased number of circuit breakers, contactors, and other components integrated inside the cabinet, along with the increased power density, significantly increases the heat generated during operation, placing higher demands on the precision and efficiency of the heat dissipation system.

[0003] Currently, most mainstream low-voltage switchgear in the industry adopts a heat dissipation structure with fixed fans and exhaust vents, but this still has the following shortcomings in practical applications:

[0004] First, traditional low-voltage switchgear often draws air from the cabinet through a single vent pipe, which makes it difficult to meet the heat dissipation needs of the components in the lower part of the cabinet. This can easily lead to localized high-temperature areas, causing components to operate at reduced rated levels or even fail.

[0005] Secondly, the inner wall of the ventilation pipe of traditional low-voltage switchgear is prone to dust accumulation, which increases airflow resistance. Regular manual disassembly and cleaning are required, which not only increases operation and maintenance costs, but may also affect the continuity of power supply due to downtime maintenance. Summary of the Invention

[0006] The purpose of this invention is to provide an energy-optimized intelligent sensor network low-voltage switchgear to solve the technical problem that existing switchgear often draws air from the cabinet through a single vent pipe, which makes it difficult to meet the heat dissipation needs of the components in the lower part of the cabinet, easily forming local high-temperature areas, leading to derating of components or even failure.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An energy-optimized intelligent sensor-connected low-voltage switchgear includes a heat dissipation mechanism mounted on the cabinet. The heat dissipation mechanism includes: a heat dissipation box fixedly connected to the top of the cabinet; four first vent pipes, all penetrating and installed on the top surface of the cabinet, with several air inlet slots for introducing hot air formed on the periphery of the pipe section inside the cabinet; two second vent pipes, also penetrating and installed on the top surface of the cabinet, used to cooperate with the first vent pipes to achieve comprehensive extraction of hot air from different height areas inside the cabinet; an air extraction assembly rotatably installed inside the heat dissipation box, used to extract air from inside the cabinet through the first or second vent pipes and deliver the air outside the heat dissipation box; and a transmission assembly for driving the air extraction assembly to rotate intermittently, so that the air extraction assembly is in sealed communication with the first or second vent pipes.

[0009] Preferably, the air extraction assembly includes: a mounting cylinder, rotatably connected to the cabinet, with an air extraction pipe mounted on its upper side and a connecting cylinder mounted on its top, the connecting cylinder having multiple strip grooves; a sleeve, rotatably fitted onto the connecting cylinder; and an exhaust pipe, one end of which is fixedly connected to and communicates with the sleeve, and the other end of which extends outside the heat dissipation box.

[0010] Preferably, the air extraction assembly further includes: a motor installed inside the mounting cylinder, with a rotating shaft mounted on its power output shaft; fan blades mounted on the rotating shaft; and a toothed plate fixedly connected to the side of the mounting cylinder.

[0011] Preferably, the transmission assembly includes: a drive disc, fixedly connected to the upper end of the rotating shaft, with a drive rod mounted on its top surface; a rotating rod, rotatably connected to the top surface of the heat sink; a turntable, fixedly sleeved on the rotating rod, with six drive grooves equidistantly provided on it to match the drive rod; and a transmission belt for connecting the rotating rod and the connecting cylinder.

[0012] Preferably, the top centers of the first and second ventilators are both located on the same virtual circle.

[0013] Preferably, the air extraction assembly further includes: four vertical rods, each rotatably connected to one of the four first vent pipes, with a cleaning brush installed on the portion of each vertical rod inside the first vent pipe; four gears, each fixedly connected to the upper end of the four vertical rods, all matching the toothed plate; and four sealing plugs, each inserted into the lower end of the four first vent pipes.

[0014] Preferably, the first ventilator is composed of an upper section, a middle section and a lower section, and the upper section and the lower section of the first ventilator are not on the same axis.

[0015] Preferably, the heat dissipation mechanism further includes a display controller, which is installed on the front of the heat dissipation box; a temperature sensor is installed inside the cabinet.

[0016] Preferably, a first pulley is mounted on the rotating rod, and a second pulley is mounted on the connecting cylinder, wherein the outer diameters of the first pulley and the second pulley are the same.

[0017] Preferably, the system further includes a dust removal mechanism, which comprises: two guide blocks, both mounted on the side of the cabinet, with heat dissipation holes provided in the portion of the cabinet located between the two guide blocks; a brush plate, slidably connected to the two guide blocks, with a second pin mounted on the side away from the cabinet; a crossbar, rotatably connected to the heat dissipation box, with a second bevel gear mounted on one end inside the heat dissipation box, a first bevel gear meshing with the second bevel gear, and the first bevel gear being fixedly connected to the lower end of a rotating rod; a disc, fixedly connected to the end of the crossbar outside the heat dissipation box, with a first pin mounted on it; and a hinge rod, with both ends hinged to the first pin and the second pin, respectively.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0019] 1. The heat dissipation mechanism of the present invention is provided with a first vent pipe, a second vent pipe and an air extraction component. The first vent pipe has an air inlet groove in the internal section of the cabinet. At the same time, the two second vent pipes are equidistantly distributed in a circle with the top of the first vent pipe. This can achieve the coverage and extraction of hot air in different areas of the cabinet. The first vent pipe extends into the lower middle part of the cabinet and directly captures the hot air generated by the components in the lower middle part through the air inlet groove, avoiding the accumulation of hot air in the lower middle part. The second vent pipe can cover the upper part of the cabinet. The two work together to cover the air extraction range of multiple areas, comprehensively reducing the temperature inside the cabinet and avoiding malfunctions caused by local high temperature.

[0020] 2. This invention, by setting up a drive disc, drive rod, turntable, rotating rod, first pulley, second pulley, and transmission belt, with the first pulley and second pulley having the same outer diameter, can convert the continuous rotation of the motor shaft into a 60° intermittent step rotation of the air extraction component. This ensures that the air extraction pipe and the six ventilation pipes are automatically and accurately connected, allowing hot air from different locations in the cabinet to be extracted sequentially without manual intervention, thus improving heat dissipation coverage and ease of operation.

[0021] 3. In this invention, by installing a toothed plate on the side of the mounting cylinder, when the mounting cylinder rotates, the toothed plate can synchronously drive the cleaning brush to rotate, so that the cleaning brush can automatically remove the dust and debris attached to the inner wall of the first vent pipe, maintain the unobstructed flow of the first vent pipe, and avoid the decrease in air extraction efficiency caused by blockage.

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them.

[0036] This invention is described in detail with reference to the accompanying drawings. When detailing the embodiments of this invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not to scale. Furthermore, the accompanying drawings are merely examples and should not be construed as limiting the scope of protection of this invention.

[0037] Furthermore, it should be noted in the description of this invention that the terms "first," "second," or "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0038] Unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" in this invention should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; similarly, they can refer to mechanical connections, electrical connections, or direct connections, or indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0039] Example 1: As Figures 1-4 As shown, an energy-optimized intelligent sensor network low-voltage switchgear includes a heat dissipation mechanism 200 installed on the cabinet 100, and a cabinet door 101 installed on the cabinet 100. The cabinet door 101 is equipped with a handle. The heat dissipation mechanism 200 includes a heat dissipation box 201, four first vent pipes 202, two second vent pipes 203, an air extraction component 210, and a transmission component 220.

[0040] The bottom of the heat dissipation box 201 is open, and the heat dissipation box 201 is fixedly connected to the top surface of the cabinet 100; four first vent pipes 202 are all installed through the top surface of the cabinet 100, and the portion of the first vent pipe 202 located inside the cabinet 100 is provided with an air inlet slot 204; two second vent pipes 203 are all installed through the top surface of the cabinet 100; the air extraction assembly 210 is used to extract air from the cabinet 100 through the first vent pipe 202 or the second vent pipe 203 and deliver the air to the outside of the heat dissipation box 201; the transmission assembly 220 is used to drive the air extraction assembly 210 to rotate intermittently, so that the air extraction assembly 210 is connected to the first vent pipe 202 or the second vent pipe 203.

[0041] The heat dissipation mechanism 200 also includes a display controller 209, which is installed on the front of the heat dissipation box 201; a temperature sensor is installed inside the cabinet 100. The display controller 209 is used to receive temperature data from the temperature sensor and display it on the screen in real time. At the same time, the display controller 209 can also control the start, stop and speed adjustment of the motor 217 according to the temperature threshold.

[0042] Specifically, when the temperature sensor detects that the temperature inside the cabinet 100 exceeds the preset value, the air extraction component 210 is activated. The air extraction component 210 extracts the hot air inside the cabinet 100 through the first vent pipe 202 or the second vent pipe 203 and delivers the hot air to the outside of the heat dissipation box 201, allowing external air to enter the cabinet 100, thereby accelerating the air circulation speed inside the cabinet 100 and facilitating the cooling of the inside of the cabinet 100.

[0043] When the air extraction component 210 is running, it will be driven to rotate intermittently through the transmission component 220. After each rotation of the air extraction component 210 by 60 degrees, the air extraction component 210 will be connected to the first vent pipe 202 or the second vent pipe 203, and hot air in the cabinet 100 will be extracted through the vent pipe connected to it.

[0044] Furthermore, since the first vent pipe 202 extends into the lower part of the cabinet 100, hot air from the lower part of the cabinet 100 can be directly extracted through the air inlet slot 204; at the same time, by connecting the air extraction component 210 with different first vent pipes 202 or second vent pipes 203, hot air from different locations inside the cabinet 100 can be extracted, thus avoiding the situation where the local temperature inside the cabinet 100 cannot be lowered.

[0045] like Figures 7-9 As shown, the air extraction assembly 210 includes an installation cylinder 211, a sleeve 215, an exhaust pipe 216, a motor 217, a fan blade 218, and a toothed plate 219.

[0046] The mounting cylinder 211 is rotatably connected to the cabinet 100. An exhaust pipe 212 is mounted on the upper side of the mounting cylinder 211, and a connecting cylinder 213 is mounted on the top of the mounting cylinder 211. Multiple slots 214 are formed on the connecting cylinder 213. The mounting cylinder 211 communicates internally with the connecting cylinder 213 and the exhaust pipe 212. A sleeve 215 is rotatably fitted onto the connecting cylinder 213. One end of the exhaust pipe 216 is fixedly connected to and communicates with the sleeve 215, and the other end of the exhaust pipe 216 extends outside the heat dissipation box 201. A motor 217 is installed inside the mounting cylinder 211. The motor 217 has a speed-regulating function. A rotating shaft 2171 is mounted on the power output shaft of the motor 217. The rotating shaft 2171 passes through the top of the connecting cylinder 213 and is rotatably connected to the connecting cylinder 213. Fan blades 218 are mounted on the rotating shaft 2171. A toothed plate 219 is fixedly connected to the side of the mounting cylinder 211.

[0047] Specifically, when the motor 217 is running, the power output shaft of the motor 217 will drive the rotating shaft 2171 to rotate, which in turn drives the fan blade 218 to rotate. The rotating fan blade 218 will transport the air in the mounting cylinder 211 to the connecting cylinder 213. The air in the connecting cylinder 213 passes through the strip groove 214 and enters the sleeve 215. The air in the sleeve 215 will then be discharged through the exhaust pipe 216.

[0048] Furthermore, since the sleeve 215 is rotatably connected to the connecting sleeve 213, the rotation of the mounting sleeve 211 and the connecting sleeve 213 will not affect the air supply from the connecting sleeve 213 to the sleeve 215.

[0049] More specifically, motor 217 has an adaptive speed regulation function based on the temperature inside cabinet 100. When the temperature sensor detects that the temperature inside cabinet 100 is 40-50℃, motor 217 runs at 50% of its rated speed; when the temperature is ≥50℃, it runs at 100% of its rated speed; when the temperature is <40℃, motor 217 stops, realizing on-demand energy allocation and reducing energy consumption.

[0050] like Figures 7-9 As shown, the transmission assembly 220 includes a drive disc 221, a rotating rod 223, a turntable 224, and a transmission belt 228. The drive disc 221 is fixedly connected to the upper end of the rotating shaft 2171, and a drive rod 222 is mounted on the top surface of the drive disc 221; the rotating rod 223 is rotatably connected to the top surface of the heat sink 201; the turntable 224 is fixedly sleeved on the rotating rod 223, and six drive grooves 225 that match the drive rod 222 are equidistantly opened on the turntable 224.

[0051] A first pulley 226 is mounted on the rotating rod 223, and a second pulley 227 is mounted on the connecting cylinder 213. The first pulley 226 and the second pulley 227 have the same outer diameter. A transmission belt 228 is fitted onto the first pulley 226 and the second pulley 227. The transmission belt 228 is a synchronous toothed belt.

[0052] Specifically, when the motor 217 drives the rotating shaft 2171 to rotate, it will drive the drive disk 221 to rotate, which in turn drives the drive rod 222 to rotate. When the drive rod 222 rotates, it will drive the turntable 224 to rotate through the drive groove 225. When the drive rod 222 rotates one revolution, the turntable 224 rotates 60 degrees.

[0053] When the turntable 224 rotates, it drives the rotating rod 223 to rotate, which in turn drives the first pulley 226 to rotate. This, in turn, drives the second pulley 227 to rotate via the transmission belt 228, which in turn drives the connecting cylinder 213 and the mounting cylinder 211 to rotate. Since the first pulley 226 and the second pulley 227 have the same outer diameter, they will rotate synchronously and rhythmically under the connection of the transmission belt 228. That is to say, when the turntable 224 rotates 60 degrees, the connecting cylinder 213, the mounting cylinder 211, and the suction pipe 212 will also rotate 60 degrees.

[0054] like Figure 4 and Figure 5 As shown, the top centers of the first vent pipe 202 and the second vent pipe 203 are both located on the same virtual circle. The axis of the mounting cylinder 211 coincides with the center of this virtual circle.

[0055] The first vent pipe 202 consists of an upper section, a middle section, and a lower section. The upper and lower sections of the first vent pipe 202 are not on the same axis. This arrangement allows the lower section of the first vent pipe 202 to be as close as possible to the inner wall of the cabinet 100, so that components can be installed in the cabinet 100.

[0056] The distance between two adjacent first vent pipes 202 is equal to the distance between adjacent first vent pipes 202 and second vent pipes 203. In other words, when viewed from the top of the six vent pipes, the six vent pipes are equidistant.

[0057] Specifically, after the mounting cylinder 211 and the suction pipe 212 rotate 60 degrees each time, or after the rotation of the mounting cylinder 211 and the suction pipe 212 is completed, the lower end of the suction pipe 212 will always be directly above a first vent pipe 202 or a second vent pipe 203 and connected to the interior of that vent pipe. More specifically, the lower end of the suction pipe 212 is equipped with a rubber elastic sealing sleeve. When the suction pipe 212 advances to directly above the vent pipe, the elastic sealing sleeve is press-fitted with the top of the vent pipe to form an airtight seal, ensuring that airflow enters the suction pipe 212 only through the vent pipe.

[0058] like Figure 5 and Figure 6 As shown, the air extraction assembly 210 also includes four vertical rods 205, four gears 207, and four sealing plugs 208. The four vertical rods 205 are rotatably connected to the four first vent pipes 202, and a cleaning brush 206 is installed on the portion of the vertical rods 205 located inside the first vent pipes 202; the four gears 207 are fixedly connected to the upper ends of the four vertical rods 205, and all four gears 207 are matched with the toothed plates 219; the four sealing plugs 208 are inserted into the lower ends of the four first vent pipes 202.

[0059] Specifically, when the mounting cylinder 211 rotates, it will drive the toothed plate 219 to rotate. When the toothed plate 219 rotates, it will drive the gear 207 that meshes with it to rotate. When the gear 207 rotates, it will drive the vertical rod 205 and the cleaning brush 206 to rotate, thereby brushing away the debris attached to the inside of the first vent pipe 202.

[0060] By setting a sealing plug 208, the sealing plug 208 can be periodically removed from the first vent tube 202 to remove debris from the first vent tube 202.

[0061] Working principle: In actual use, when the temperature sensor detects that the temperature inside the cabinet 100 exceeds the preset value, the display controller 209 will control the start motor 217 to start.

[0062] When the motor 217 is running, the power output shaft of the motor 217 will drive the rotating shaft 2171 to rotate, which in turn drives the fan blade 218 to rotate. The rotating fan blade 218 will transport the air in the mounting cylinder 211 to the connecting cylinder 213. The air in the connecting cylinder 213 passes through the strip groove 214 and enters the sleeve 215. The air in the sleeve 215 will then be discharged through the exhaust pipe 216. This allows external air to enter the cabinet 100, thereby accelerating the air circulation speed inside the cabinet 100 and facilitating the cooling of the inside of the cabinet 100.

[0063] Because the tops of the six vent pipes are equidistantly distributed in a circular pattern, when the motor 217 drives the drive disc 221 to rotate one revolution via the shaft 2171, the drive rod 222 will also rotate one revolution, which will then drive the turntable 224 to complete a 60-degree step rotation via the drive groove 225. Since the first pulley 226 and the second pulley 227 have the same outer diameter and are synchronously driven, for every 60° step rotation of the turntable 224, the connecting cylinder 213, the mounting cylinder 211, and the extraction pipe 212 also synchronously rotate 60°. After the rotation of the mounting cylinder 211 and the extraction pipe 212 is completed, the lower end of the extraction pipe 212 will always be directly above a first vent pipe 202 or a second vent pipe 203 and connected to the interior of that vent pipe. The extraction assembly 210 will then extract the hot air from the cabinet 100 via the first vent pipe 202 or the second vent pipe 203 it is connected to.

[0064] Furthermore, since the first vent pipe 202 extends into the lower part of the cabinet 100, hot air from the lower part of the cabinet 100 can be directly extracted through the air inlet slot 204; at the same time, by connecting the air extraction component 210 with different first vent pipes 202 or second vent pipes 203, hot air from different locations inside the cabinet 100 can be extracted, thus reducing the temperature inside the cabinet 100 more comprehensively.

[0065] When the mounting cylinder 211 rotates, it drives the toothed plate 219 to rotate. When the toothed plate 219 rotates, it drives the gear 207 that meshes with it to rotate. When the gear 207 rotates, it drives the vertical rod 205 and the cleaning brush 206 to rotate, thereby brushing away the debris attached to the inside of the first vent pipe 202 and preventing the debris from affecting the efficiency of the first vent pipe 202 in delivering air.

[0066] Example 2: As Figure 2 , Figure 8 and Figure 9 As shown, while all other parts are the same as in Example 1, the difference between this example and Example 1 is that:

[0067] The energy-optimized intelligent sensor network low-voltage switchgear also includes a dust removal mechanism 110, which includes two guide blocks 111, a brush plate 112, a crossbar 114, a disc 116, and a hinge rod 118.

[0068] Two guide blocks 111 are installed on the side of the cabinet 100. The part of the cabinet 100 between the two guide blocks 111 is provided with heat dissipation holes 102. The brush plate 112 is slidably connected to the two guide blocks 111. A second pin 113 is installed on the side of the brush plate 112 away from the cabinet 100. The crossbar 114 is rotatably connected to the heat dissipation box 201. A second bevel gear 115 is installed on the end of the crossbar 114 inside the heat dissipation box 201. A first bevel gear 229 is meshed on the second bevel gear 115. The first bevel gear 229 is fixedly connected to the lower end of the rotating rod 223. The disc 116 is fixedly connected to the end of the crossbar 114 outside the heat dissipation box 201. A first pin 117 is installed on it. The two ends of the hinge rod 118 are respectively hinged to the first pin 117 and the second pin 113.

[0069] Working principle: In actual use, when the rotating rod 223 rotates, it drives the first bevel gear 229 to rotate, which in turn drives the crossbar 114 to rotate via the second bevel gear 115. When the crossbar 114 rotates, it drives the disc 116 to rotate, which in turn drives the hinge rod 118 to move via the first pin 117. This, in turn, drives the second pin 113 and the brush plate 112 to move up and down reciprocally. When the brush plate 112 moves, it cleans the heat dissipation holes 102 on the cabinet 100, removing debris attached to the heat dissipation holes 102 and preventing them from clogging. By cleaning the heat dissipation holes 102, the natural heat dissipation efficiency of the cabinet 100 can be improved, reducing the starting frequency of the motor 217.
