Description

Technical Field

[0001] The invention relates to the technical field of control cabinets, in particular to an intelligent power-saving control cabinet. Background Art

[0002] The control cabinet is a closed or semi-closed metal cabinet that assembles switchgear, measuring instruments, protective electrical appliances and auxiliary equipment according to the requirements of electrical wiring. Its layout should meet the requirements of normal operation of the power system, facilitate maintenance, and not endanger the safety of people and surrounding equipment. In normal operation, the circuit can be connected or disconnected with the help of manual or automatic switches. In case of failure or abnormal operation, the circuit can be cut off or alarmed with the help of protective electrical appliances. The measuring instruments can display various parameters in operation, and some electrical parameters can be adjusted, and prompts or signals can be issued for deviations from normal working conditions.

[0003] When the control cabinet is out of use, the internal controller will emit heat. Currently, it is more common to install a fan on the side wall of the control cabinet to take away the heat through airflow. However, since the fan blows external air into the controller in the cabinet, and the external airflow carries dust, a lot of dust will adhere to the inner wall of the control cabinet and the controller after long-term use. The dust will corrode the printed wires in the circuit board, the metal pins of the electronic components, etc., and even cause them to break, making the control invalid or inoperative. Dust accumulates on the circuit board, heating devices or heat dissipation devices, which will affect their heat dissipation effect and easily cause failures; and the above problems will lead to increased power consumption of the control cabinet.

[0004] A control cabinet is proposed in the patent with publication number CN110351989A. Since the dust baffle is tilted and located above the air outlet, and several dust baffles are staggered in sequence in the horizontal direction, the airflow can act on the dust baffles one by one. Under the guidance of the tilted dust baffles, the airflow can enter the cabinet and dissipate the heat of the controller in the cabinet to ensure the heat dissipation effect. Before entering the cabinet, the airflow acts on the dust baffle in advance, and the dust in the airflow can adhere to the dust baffle, thereby preventing dust from accumulating on the controller in the cabinet and affecting stability.

[0005] The above solution can effectively prevent dust from entering the cabinet, but it cannot completely prevent dust, resulting in dust still existing in the cabinet.

[0006] Generally, for the dust in the control cabinet, the staff will use negative pressure adsorption or positive pressure soot blowing to clean it. Compared with positive pressure soot blowing, negative pressure adsorption will not cause dust to spread, which has a positive effect on the health of the operators. However, the range of negative pressure adsorption is only a few centimeters, or even only 2 cm. But in actual application scenarios, the depth of the control cabinet can reach one meter, resulting in the inability to completely adsorb the negative pressure. In addition, when working in actual scenarios, the staff holding the high-pressure air pipe for soot blowing or soot suction needs to put their heads into the cabinet to find the cleaning position, which increases the risk of the operator inhaling dust. Summary of the invention

[0007] In view of the deficiencies in the prior art, the present invention provides an intelligent power-saving control cabinet, which solves the problems in the prior art of dust diffusion caused by positive pressure soot blowing, inability to completely adsorb dust due to negative pressure, and impact on the health of workers.

[0049] (1) The intelligent power-saving control cabinet adjusts its own working state by controlling the electrical frequency of the variable frequency air pump to achieve dust cleaning and heat dissipation of the device. The suction component and the blowing component are arranged opposite to each other with the components as the center, so that dust blowing and dust suction can be carried out quickly and in a targeted manner, which not only ensures the cleaning of the control cabinet with a large depth, but also avoids the spread of dust and the impact on the health of the staff.

[0050] (2) In the intelligent power-saving control cabinet, the variable frequency air pump works with a closed air outlet in the cleaning state. The closed air outlet can speed up the flow rate of the gas blowing on the components, thereby improving the soot blowing effect. After the dust is reduced, it can avoid obstruction of the air flow channel in the cabinet, avoid affecting the heat dissipation function of the equipment, and avoid causing faults such as circuit short circuit and poor contact. In addition, since the cleaning state includes both soot blowing and soot suction, it can reduce the spread of dust and avoid dust flying in the workshop. In the heat dissipation state, the air outlet is the flared air outlet, which can reduce the flow rate of the air blowing on the components, thereby avoiding dust flying in the cabinet when not in the cleaning state.

[0051] (3) The intelligent power-saving control cabinet can dissipate heat through the vents in a natural static state, and in the dust-cleaning state, high-pressure gas enters the power pipeline to push the sealing plate to automatically block the vents, preventing the dust blown out of the cabinet from spreading out from the vents, thereby ensuring the health of the workshop workers.

DETAILED DESCRIPTION

[0065] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0066] Embodiment 1

[0067] See also Figure 1As shown, an embodiment of the present invention provides an intelligent power-saving control cabinet, including a cabinet body 100 and components 600 located in the cabinet body 100, wherein the components 600 include but are not limited to switching power supplies, transformers, plugs, sockets, terminals, connectors, inverters, motor protectors, and motor contactors. Preferably, a wire box 130 for accommodating cables is also installed in the cabinet body 100.

[0068] A variable frequency air pump 200 is also provided, and the variable frequency air pump 200 is located on the upper side of the cabinet 100. The variable frequency air pump 200 can pump air at high pressure when working at high frequency, and vice versa, the variable frequency air pump 200 can pump air at low pressure when working at low frequency.

[0069] Combination Figure 1 - Figure 4 As shown, in order to enable the variable frequency air pump 200 to clean the dust in the cabinet 100, an air suction component 300, an air blowing component 500 and a filter component 400 are provided. The air suction component 300 and the air blowing component 500 are both located in the cabinet 100. The air blowing component 500 can blow dust at high pressure. The air suction component 300 can suck away the airflow carrying dust in the cabinet 100. The filter component 400 can filter the airflow absorbed by the variable frequency air pump 200 from the air suction component 300 and transport the filtered airflow to the air blowing component 500, thereby completing the entire cleaning cycle.

[0070] In order to enable the variable frequency air pump 200 to dissipate heat for the components 600 in the cabinet 100, an external air intake pipe 210 is also provided. The external air intake pipe 210 connects the outside air with the air inlet of the variable frequency air pump 200, so that the variable frequency air pump 200 can also inhale air from the outside. The inhaled gas is blown onto the components 600 from the blowing assembly 500 in a low-pressure state to dissipate heat for the components 600.

[0071] It is also necessary to set solenoid valves on the suction component 300, the blowing component 500 and the external suction pipe 210 to control the opening and closing of the relative pipelines.

[0072] like Figure 4-Figure 6As shown, it should be noted that, in order to realize that the blowing assembly 500 can blow out high-pressure and high-speed airflow when the variable frequency air pump 200 pumps out high-pressure gas, and can blow out low-pressure and low-speed airflow when the low-pressure gas is pumped out, the blowing assembly 500 here includes a blowing head 530, and the blowing head 530 includes an expanding outlet head 531 and a closing outlet head 532 arranged side by side, and an adjustment structure for controlling the opening of the expanding outlet head 531 or the closing outlet head 532. When the variable frequency air pump 200 works at a high frequency, The solenoid valve on the external suction pipe 210 is closed, and the solenoid valves on the blowing component 500 and the suction component 300 are opened. The dust-carrying airflow can be absorbed from the cabinet 100 through the suction component 300. The dust-carrying airflow is filtered by the filter component 400 and then enters the cabinet 100 through the closed air outlet head 532 at high pressure. At this time, the closed air outlet head 532 is in an open state. Due to its closed state, the flow rate and pressure of the ejected airflow are increased, thereby improving the soot blowing effect and forming the first state of soot blowing and soot suction.

[0073] Therefore, in the first state, high-pressure blowing can be achieved through the closed air outlet head 532 to blow away the dust on the components 600. At the same time, the suction component 300 can suck away the airflow carrying dust and filter it through the filter component 400. The filtered clean gas can be blown onto the components 600 again through the blowing component 500 at high pressure. Moreover, since the suction component 300 and the blowing component 500 are distributed on both sides of each row of components 600, they can blow and suck air quickly and specifically to reduce the spread of dust and avoid dust flying in the workshop.

[0074] When the variable frequency air pump 200 works at a low frequency, it can absorb airflow from the outside through the external air suction pipe 210, and dissipate heat to the components 600 through the flared air outlet head 531, thereby forming a second state of heat dissipation.

[0075] In the second state, the solenoid valve on the air intake assembly 300 is closed, the solenoid valve on the external air intake pipe 210 is opened, the closing air outlet head 532 is closed, the expanding air outlet head 531 is opened, the variable frequency air pump 200 operates at a low frequency and inhales air from the external air intake pipe 210. The outside air passes through the expanding air outlet head 531 and blows softly onto the component 600 to prevent dust from spreading during the heat dissipation stage.

[0076] In summary, the intelligent power-saving control cabinet provided by the embodiment of the present invention adjusts its own working state by controlling the electrical frequency of the variable frequency air pump 200. One of the working states is the cleaning state. In the cleaning state, the closed air outlet head 532 works. The closed air outlet head 532 can speed up the flow rate of the gas blown on the component 600, thereby improving the soot blowing effect. After the dust is reduced, it can avoid obstruction of the air circulation channel in the cabinet 100, avoid affecting the heat dissipation function of the equipment, and avoid causing circuit short circuits, poor contact and other faults; and because the cleaning state includes both soot blowing and soot suction, it can reduce the spread of dust and avoid dust flying in the workshop.

[0077] The second working state is the heat dissipation state. During heat dissipation, the air is discharged through the flared air outlet head 531, which can reduce the flow rate of the airflow blowing on the components 600, thereby avoiding the situation where dust flies in the cabinet 100 when the dust is not cleaned.

[0078] In addition, it should be noted that a temperature sensor should be assembled in the cabinet 100. When the temperature reaches the threshold, the controller controls the variable frequency air pump 200 to perform heat dissipation operations at a low frequency, and at the same time controls the solenoid valve on the external suction pipe 210 to open, the solenoid valve of the suction component 300 to close, and the solenoid valve of the blowing component 500 to open.

[0079] When cleaning is required, the cleaning button assembled on the cabinet door 110 can be directly pressed to control the internal components 600 to cut off the power. At this time, the solenoid valve on the external suction pipe 210 is closed, the solenoid valve of the suction component 300 is opened, and the solenoid valve of the blowing component 500 is opened.

[0080] Combination Figure 6 - Figure 8 As shown, in order to realize the purpose of automatically opening the closed air outlet head 532 in the dust cleaning state and opening the expanded air outlet head 531 in the heat dissipation state, the adjustment structure mentioned above is the adjustment structure 1 533, and the adjustment structure 1 533 includes an air box 5331 for air intake, and the expanded air outlet head 531 and the closed air outlet head 532 are installed side by side on one side of the air box 5331. The interior of the air box 5331 is equipped with a wind-receiving fan 5332 through a torsion spring rotation. When the variable frequency air pump 200 blows out high-pressure gas When the wind receiving fan 5332 rotates, the high-pressure gas can drive the wind receiving fan 5332 to rotate, and the valve plate 5336 is fixed on the central axis of the wind receiving fan 5332, and a through hole 5333 is opened on the valve plate 5336. Therefore, when the wind receiving fan 5332 rotates, the valve plate 5336 can be driven to rotate, so that the through hole 5333 is opposite to the closing air outlet head 532. At this time, the closing air outlet head 532 can be opened, and the through hole 5333 on the valve plate 5336 is aligned with the expanding air outlet head 531 in the natural state of the torsion spring.

[0081] In more detail, in order to prevent the high-pressure gas continuously input into the air box 5331 from driving the blower fan 5332 to continuously rotate and causing the through hole 5333 to be separated from the closing air outlet head 532, a limit slider 5334 is also provided. The limit slider 5334 is integrally arranged on one side of the valve plate 5336, and a limit groove 5335 adapted to the limit slider 5334 is provided in the air box 5331, and the limit groove 5335 limits the valve plate 5336 from rotating 180°, so that the through hole 5333 of the valve plate 5336 will no longer rotate after being aligned with the closing air outlet head 532.

[0082] Therefore, the intelligent power-saving control cabinet provided by the embodiment of the present invention can automatically use the closed-end air outlet head 532 to blow air in the dust cleaning state, and can automatically use the expanded-end air outlet head 531 to blow air in the heat dissipation state.

[0083] Combination Figure 3 and Figure 4 As shown, the air blowing assembly 500 also includes an air blowing main pipe 510 and an air blowing branch pipe 520, one end of the air blowing main pipe 510 is fixedly connected to the filter assembly 400, and the other end of the air blowing main pipe 510 is located in the cabinet 100; the air blowing branch pipe 520 is located in the cabinet 100 at a position opposite to the component 600, and the air blowing branch pipe 520 is fixedly connected to the air blowing main pipe 510, and an assembly pipe 534 is provided on the adjustment structure, wherein the assembly pipe 534 is fixedly connected to the air box 5331, and the other end of the assembly pipe 534 is fixedly connected to the air blowing branch pipe 520.

[0084] In this embodiment, the gas blown out of the gas outlet of the variable frequency air pump 200 can first be filtered by the filter assembly 400, and the filtered gas can be blown onto the component 600 through the blowing main pipe 510, the blowing branch pipe 520, the assembly pipe 534, the air box 5331, the through hole 5333 and the closed outlet head 532 (blowing state) or the expanded outlet head 531 (heat dissipation state) in sequence.

[0085] Continue to refer to Figure 3 and Figure 4 As shown, the air suction component 300 includes an air suction main pipe 310 and an air suction branch pipe 330, one end of the air suction main pipe 310 is fixed on the air inlet of the variable frequency air pump 200, and the other end of the air suction main pipe 310 is located in the cabinet 100, the air suction branch pipe 330 is located at a position opposite to the blowing branch pipe 520, and the air suction branch pipe 330 is fixed with an expanding air suction head 320 opposite to the blowing head 530, so that the air flow after soot blowing from the closing air outlet head 532 can directly enter the expanding air suction head 320.

[0086] Preferably, a pipe box 120 for accommodating the air suction branch pipe 330 and the air blowing branch pipe 520 is further provided in the cabinet 100 .

[0087] like Fig. 9As shown, in the non-cleaning state and the non-heat dissipation state, the control cabinet should also have a static state. In this static state, the variable frequency air pump 200 is in a non-working stage. In order to ventilate the inside and outside of the cabinet 100 at this stage, a vent 810 is opened on one side of the cabinet 100. A filter plate 820 is assembled in the vent 810. The cabinet 100 can directly perform static heat dissipation through the filter plate 820, and the filter plate 820 can also prevent foreign matter from entering the cabinet 100.

[0088] In actual application scenarios, in the cleaning state, the dust in the cabinet 100 flies out from the filter plate 820. In order to avoid the flying of dust inside the workshop caused by this situation, a sealing plate 900 is provided on the side of the cabinet 100 close to the vent 810, and a slide 910 for the sealing plate 900 to slide is provided on the cabinet 100. A power component 700 is provided on the side of the cabinet 100 close to the sealing plate 900. The power component 700 is used to control the sealing plate 900 to cover or detach from the vent 810. In the cleaning state, the sealing plate 900 covers the vent 810, thereby preventing the dust in the cabinet 100 from overflowing.

[0089] Combination Fig. 9 and Fig.10 As shown, in order to enable the power component 700 to automatically push the sealing plate 900 to cover the vent 810 in the dust cleaning state, the power component 700 here includes an outer cylinder body 710, a piston rod 720 and a spring 740. The outer cylinder body 710 is fixed on the cabinet body 100, and a piston body 730 is axially slidably arranged in the outer cylinder body 710. One end of the piston rod 720 is fixedly connected to the piston body 730, and the other end of the piston rod 720 is fixedly connected to the sealing plate 900. The spring 740 is located between the piston rod 720 and the end of the outer cylinder body 710.

[0090] In this embodiment, when the piston body 730 is subjected to pressure, the high-pressure gas can push the piston rod 720 to move downward, so that the piston rod 720 can push the sealing plate 900 downward, and at this time the spring 740 is in a compressed state; when the piston body 730 loses pressure, the rebound of the spring 740 can cause the piston rod 720 to pull the sealing plate 900 upward, so that it disengages from the vent 810.

[0091] A power pipeline 540 is also provided on one side of the air blowing main pipe 510, and the power pipeline 540 is connected to the outer cylinder body 710, so that the piston body 730 moves downward when there is high-pressure gas in the power pipeline 540, that is, in the cleaning state, high-pressure gas can enter the power pipeline 540, so that the piston body 730 can move downward to make the sealing plate 900 block the vent 810, and then once in the cleaning state, the high-pressure gas can push the piston body 730 through the power pipeline 540, so that the piston rod 720 presses down the sealing plate 900, so that the sealing plate 900 blocks the vent 810, thereby preventing the dust blown in the cabinet 100 from spreading outward from the vent 810.

[0092] Therefore, the intelligent power-saving control cabinet provided by the embodiment of the present invention can dissipate heat through the vents 810 in a natural static state, and the sealing plate 900 can automatically block the vents 810 in a clean state to prevent dust blown in the cabinet 100 from spreading outward from the vents 810, thereby ensuring the health of workshop workers.

[0094] In more detail, the above-mentioned filter main structure 420 includes a filter bag 423; in this embodiment, the airflow discharged from the air outlet of the variable frequency air pump 200 can pass through the connecting pipe 410, and enter each filter main structure 420 in turn, and enter the filter bag 423 for filtration, and the filtered gas can reach the blowing main pipe 510.

[0095] In addition, a support plate 421 and an outer shell 424 are provided. The support plate 421 is fixed on the cabinet 100, and ribs 422 are provided between the support plates 421. An assembly space is formed between the plurality of ribs 422. The filter bag 423 is assembled in the outer shell 424, and the outer shell 424 is embedded in the assembly space. A handle 425 is assembled on the other side of the outer shell 424. When the filter bag 423 needs to be cleaned, the outer shell 424 can be directly pulled out of the assembly space by pulling the handle 425, and the filter bag 423 can be taken out of the outer shell 424.

[0096] Preferably, an auxiliary exhaust pipe 220 is also provided at the exhaust port of the variable frequency air pump 200, and the other end of the auxiliary exhaust pipe 220 is inserted in the cabinet 100. The auxiliary exhaust pipe 220 can be used as a heat dissipation channel, that is, in the heat dissipation state, the solenoid valve on the auxiliary exhaust pipe 220 is also open, so that the low-pressure airflow of the variable frequency air pump 200 can also reach the cabinet 100 from the auxiliary exhaust pipe 220 to dissipate the heat of the components 600 therein.

[0097] When in use, 1) in a stationary state, the components 600 in the cabinet 100 are cooled through the vents 810, and the filter plate 820 can reduce the dust entering the cabinet 100. In this state, all solenoid valves are closed;

[0098] 2) When the temperature sensor detects that the temperature inside the cabinet 100 is too high, the controller controls the variable frequency air pump 200 to work at a low frequency, and controls the solenoid valve of the air suction component 300 to close, the solenoid valve on the external air suction pipe 210 to open, and the solenoid valve on the air blowing component 500 to open. At this time, the variable frequency air pump 200 inhales air from the outside through the external air suction pipe 210, and the air flow is filtered by the filter component 400 and reaches the air blowing main pipe 510, the air blowing branch pipe 520, the assembly pipe 534, the air box 5331, the through hole 5333 and the expanded air outlet head 531 to blow on the components 600, and dissipate the heat of the components 600. At the same time, the external gas absorbed by the variable frequency air pump 200 can also be blown into the cabinet 100 through the auxiliary exhaust pipe 220 to dissipate the heat inside the cabinet 100;

[0099] 3) When dust cleaning is required, by pressing the dust cleaning button, the controller controls the solenoid valve on the external suction pipe 210 to close, the solenoid valve on the blowing assembly 500 to open, the solenoid valve on the auxiliary exhaust pipe 220 to open, and the solenoid valve on the suction assembly 300 to open, and controls the variable frequency air pump 200 to work at high frequency, so that it can inhale through the suction assembly 300, and transport the airflow to the filter assembly 400 for filtration. The filtered airflow can reach the blowing main pipe 510, the blowing branch pipe 520, the assembly pipe 534 and the air box 5331. At this time, the wind-receiving fan 5332 rotates due to the pressure of the high-pressure airflow, and aligns the through hole 5333 with the closing air outlet head 532 to open the closing air outlet head 532, so that the high-pressure airflow can be accelerated to be ejected through the closing air outlet head 532 to blow dust off the components 600.

[0103] In this embodiment, when the low-pressure airflow in the blowing branch pipe 520 enters the air pipe 5351, it can be directly discharged through the expanded air outlet head 531 at a low pressure and low speed to dissipate heat to the component 600; when the high-pressure airflow in the blowing branch pipe 520 enters the air pipe 5351, it can push the first valve plate 5353, so that the first valve plate 5353 Fig.12 The valve body 531 moves to the left from the perspective shown, and the second valve plate 5354 is dragged to the left by connecting rod 1 5356 and connecting rod 2 5357, so that the second valve plate 5354 covers and closes the flared air outlet head 531. At this time, the first valve plate 5353 moves to the far left, so that the air flow can be ejected from the closed air outlet head 532 at a high speed and high pressure to clean the component 600.

[0104] Preferably, a second spring 5355 is further provided, and the second spring 5355 is fixedly arranged between the first valve plate 5353 and the air pipe 5351, so that when the air pipe 5351 loses the high pressure state, the second spring 5355 can rebound to reset the first valve plate 5353 and the second valve plate 5354 to the position where the first valve plate 5353 and the second valve plate 5354 are in the same position. Fig.12 Status shown.

[0105] In addition, a guide rod 5352 is installed in the air pipe 5351 to guide the spring 2 5355 and the first valve plate 5353 to maintain the stable expansion and contraction of the spring 2 5355 and the stable movement of the first valve plate 5353.
