Description

Technical Field

[0001] This invention relates to the field of power distribution cabinet accessories technology, specifically to an intelligent energy-saving power distribution device for smart buildings and its usage method. Background Technology

[0002] There are many types of intelligent energy-saving power distribution equipment used in smart buildings, among which the most important is the power distribution cabinet. Currently, the cooling strategy of the power distribution cabinet is usually uniform cooling. If it is insufficient, the operating power of the heat dissipation unit is increased. This leads to differences in power consumption between different functional areas in the building. When reflected in the power distribution cabinet, some lines are not cooled sufficiently. For example, the modular high-efficiency power distribution cabinet disclosed in CN119171239B, although it improves the heat exchange capacity by setting liquid cooling components, the electrical equipment that comes into contact with the coolant first has a significantly better cooling effect than the electrical equipment that comes into contact with the coolant later, and it cannot cool according to the heat generation of different lines.

[0003] The low-voltage distribution cabinet assembly disclosed in announcement number CN118487146B can change the direction of airflow, but it requires the use of multiple motors working together, and all of them are located inside the cabinet, which increases the heat source. Whether the cooling effect can offset the temperature increase caused by the increased heat source remains to be verified.

[0004] Therefore, a smart energy-saving power distribution device for smart buildings and its usage method are proposed. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an intelligent energy-saving power distribution device and its usage method for smart buildings, solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an intelligent energy-saving power distribution device for smart buildings, comprising a power distribution cabinet with a heat dissipation unit, a control panel fixed to the front of the power distribution cabinet, a circuit breaker group installed inside the power distribution cabinet to control the power consumption status, and a back plate installed on the back of the power distribution cabinet. The back plate is provided with a control component for changing the cooling mode and an auxiliary component for changing the cooling effect. The control component includes:

[0007] The power push rod, with one end fixed inside the power distribution cabinet, provides power for changing the cooling mode;

[0008] The compression rod is located below the power push rod and moves under the drive of the power push rod;

[0009] The sliding block slides against the extrusion rod at the top and moves downward under the squeezing action of the extrusion rod;

[0010] The top of the air intake plate slides against the bottom of the sliding block, and the angle changes under the drive of the sliding block to switch to different cooling modes.

[0011] Preferably, the control assembly further includes: a driven magnet, one end of which is fixed to the side wall of the extrusion rod; and an active electromagnet, located in front of the driven magnet, which is magnetically attracted to the driven magnet after being energized, driving the air duct to change angle and switch to different cooling modes.

[0012] Preferably, the control assembly further includes: a sliding rod, the sidewall of which is fixed to the output end of the power push rod; a combination plate, the top of which is fixed to the bottom of the sliding rod and slidably sleeved on the extrusion rod to provide support for the extrusion rod; and a sliding plate, one end of which is fixed to the sidewall of the sliding block to provide support for the sliding block.

[0013] Preferably, the control assembly further includes: a limiting post, one end of which is fixed to the top of the air-guiding plate and the other end of which slides through the sliding plate to limit the movement direction of the sliding plate; and a spring, one end of which is fixed to the top of the air-guiding plate and the other end of which is fixed to the bottom of the sliding plate to provide the sliding plate with a resetting elastic force.

[0014] Preferably, the control assembly further includes: a sliding sleeve, which is movably mounted on the side wall of the air intake plate via a support shaft; a limiting rod, one end of which is slidably inserted into the sliding sleeve; and a second spring, one end of which is fixed inside the sliding sleeve and the other end of which is fixed to the limiting rod, providing the limiting rod with the elastic force required for resetting.

[0015] Preferably, the back panel is further provided with a cooling assembly, which includes: an air duct, one end of which is fixed to the back panel to guide cold air into the power distribution cabinet; a baffle plate, one end of which slides through the air duct into the power distribution cabinet to change the cross-sectional area through which the air duct can pass; a guide rod, one end of which is fixed inside the baffle plate and the other end of which slides through the back panel; and an adjusting push rod, one end of which is fixed to the back panel by a mounting plate and the other end of which is fixed to the bottom of the guide rod to change the position of the baffle plate.

[0016] Preferably, the auxiliary component includes: a fixed frame, the bottom of which is fixed to the bottom of the inner wall of the air duct; a mounting shaft, which is hinged to the fixed frame by a torsion spring; an auxiliary plate, which is fixedly mounted on the mounting shaft; and an airbag, the bottom of which is fixed to the bottom of the inner wall of the fixed frame, and the side wall of which slides against the side wall of the auxiliary plate.

[0017] Preferably, the auxiliary component further includes: a pressure rod, which is hinged to the fixed frame via a rotating shaft and a worm spring; an auxiliary magnet, whose side wall is fixed to the pressure rod; and an adjusting electromagnet, one end of which is fixed to the side wall of the wind baffle plate, which is attracted to the magnetic field of the auxiliary magnet after being energized, thereby changing the cooling effect.

[0018] This invention also provides a method for using an intelligent energy-saving power distribution device suitable for smart buildings, comprising the following steps:

[0019] S1, in normal cooling mode, the operation of the heat dissipation unit is controlled by the control panel to ventilate and cool the circuit breaker group inside the power distribution cabinet.

[0020] S2. Monitor the temperature of the circuit breaker group;

[0021] S3. Based on the monitoring results of step S2, if the circuit breaker group experiences different heating levels in different lines due to different power demand in different zones within the building, the control panel will activate the control components to switch the cooling mode.

[0022] S4. If the cooling requirement cannot be met after switching the cooling mode, start the auxiliary component from the control panel.

[0023] S5. If the cooling zone needs cannot be met after the auxiliary components are started, the operating power of the cooling unit can be changed by the control panel.

[0024] S6. After the cooling demand of the circuit breaker group decreases and becomes almost the same, switch back to normal cooling mode.

[0025] Preferably, the time required for the control component to switch cooling modes is between 1 and 3 seconds.

[0026] This invention provides an intelligent energy-saving power distribution device and its usage method for smart buildings. Compared with the prior art, it has the following advantages:

[0027] (1) The intelligent energy-saving power distribution equipment and its usage method used in this smart building can determine the degree of heat generation inside the distribution cabinet by detecting the current carried by the circuit breaker group (reflecting the load status), and adjust the passable area of ​​the air duct and the operating power of the heat dissipation unit accordingly to avoid wasting energy by "full load operation". When the load is low, the fan speed is reduced or the air intake area is reduced to achieve energy-saving operation, reduce the frequent start-stop and high load operation of the heat dissipation device, and improve its service life. It can collect and analyze data in real time. In the future, machine learning models can be introduced to predict load trends and adjust the heat dissipation strategy in advance.

[0028] (2) The intelligent energy-saving power distribution equipment and usage method used in this smart building no longer adopts the "overall air supply" mode, but precisely directs the cold air to the circuit breaker group with high load and high heat generation, significantly improving the local heat dissipation efficiency, avoiding "overcooling" in low load areas, saving energy, effectively preventing local overheating in high load areas, improving the stability of equipment operation, and maintaining good heat dissipation performance when the building's power consumption is uneven (such as high load in the office area during the day and high load in the lighting area at night), realizing "graded heat dissipation" control, taking into account both energy saving and safety.

[0029] (3) The intelligent energy-saving power distribution equipment and its usage method used in the smart building introduce the Bernoulli effect (i.e., by using a variable cross-section design to increase the wind speed in narrow places) in the air duct structure. It can improve the wind speed and cooling efficiency without increasing the fan power, avoid the energy waste caused by blindly increasing the fan power, improve the cooling efficiency under unit energy consumption, and at the same time, it does not increase the additional heat dissipation requirements. It adopts a three-level response mechanism, with each level of response corresponding to different load states, avoiding the high energy consumption operation of "one-step" operation, improving the system robustness, adapting to different working conditions, extending the life of heat dissipation equipment, and reducing the failure rate.

[0030] Other features and advantages of the invention will be set forth in the detailed description that follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of the invention can be realized and obtained by means of the structures particularly pointed out in the written description and drawings.

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] Please see Figures 1 to 13 The present invention provides the following technical solutions:

[0047] Example 1: A smart energy-saving power distribution device for smart buildings includes a power distribution cabinet 1 with a heat dissipation unit, a control panel 11 fixedly installed on the front of the power distribution cabinet 1, a circuit breaker group 12 detachably installed inside the power distribution cabinet 1 to control the power consumption status, and a back plate 13 detachably installed on the back of the power distribution cabinet 1. The back plate 13 is equipped with a cooling assembly, and has an air inlet and an air outlet. The air inlet is located above the air outlet. The cooling assembly includes:

[0048] One end of the air duct 2 is fixedly installed at the air inlet on the back plate 13. The air duct 2 is used to guide cold air into the power distribution cabinet 1. One end of the baffle plate 21 slides through the air duct 2 into the power distribution cabinet 1. The baffle plate 21 is used to change the cross-sectional area through which the air duct 2 can pass. One end of the guide rod 23 is fixedly installed in the baffle plate 21. The other end of the guide rod 23 slides through the back plate 13. One end of the adjusting push rod 22 is fixedly installed on the back plate 13 through the mounting plate. The other end of the adjusting push rod 22 is fixedly installed at the bottom of the guide rod 23. The adjusting push rod 22 is used to change the position of the baffle plate 21.

[0049] In use, the circuit breaker group 12 in the power distribution cabinet 1 controls the power supply to various areas of the building. The control panel 11 determines the power supply share according to the power demand of different areas of the building. An air inlet is opened at the upper part of the back panel 13 and an air outlet is set at the lower part of the back panel 13, and both are equipped with necessary dustproof and moisture-proof measures. A wind baffle 21 is slidably installed in the air duct 2. The wind baffle 21 is supported by the guide rod 23. The guide rod 23 slides with the back panel 13. The back panel 13 provides support to the adjusting push rod 22, and the adjusting push rod 22 provides support to the guide rod 23.

[0050] When the overall power demand in the building decreases, the current passing through the circuit breaker group 12 decreases, and the heat converted from the lost energy decreases. The control panel 11 controls the adjustment push rod 22 to start, which causes the adjustment push rod 22 to move the guide rod 23 down, and the guide rod 23 to move the wind baffle 21 down, which reduces the passable area of ​​the air duct 2 and simultaneously reduces the operating power of the heat dissipation unit.

[0051] When the overall demand in the building increases, the circuit breaker group 12 will bear a larger current, thereby generating more heat. At this time, the operating power of the heat dissipation unit is increased by controlling the control panel 11, and the adjustment push rod 22 is activated to drive the guide rod 23 to move upward, so that after the wind baffle 21 moves upward, the passable area of ​​the air duct 2 increases.

[0052] Example 2, the technical solution of which differs from Example 1 includes: a control component for changing the cooling mode is provided on the back plate 13, the control component including:

[0053] One end of the power push rod 3 is fixedly installed inside the power distribution cabinet 1. The power push rod 3 is used to provide power for changing the cooling mode. The side wall of the sliding rod 31 is fixedly installed on the output end of the power push rod 3. The top of the combination plate 32 is fixedly installed on the bottom of the sliding rod 31. The combination plate 32 is slidably sleeved on the pressing rod 33. The combination plate 32 is used to provide support for the pressing rod 33. The pressing rod 33 can move linearly along the combination plate 32 under the drive of the power push rod 3. The top of the sliding block 34 is provided with an inclined surface. The inclined surface of the sliding block 34 slides against the pressing rod 33. 4 can move downward under the squeezing of the squeezing rod 33. One end of the sliding plate 35 is fixedly installed on the side wall of the sliding block 34. The sliding plate 35 is used to provide support for the sliding block 34. One end of the limiting post 36 is fixedly installed on the top of the air guide plate 311. The other end of the limiting post 36 slides out from the sliding plate 35. The limiting post 36 is used to limit the movement direction of the sliding plate 35. One end of the spring 37 is fixedly installed on the top of the air guide plate 311. The other end of the spring 37 is fixedly installed on the bottom of the sliding plate 35. The spring 37 can provide the sliding plate 35 with a restoring elastic force.

[0054] The side wall of the sliding sleeve 38 is movably mounted on the side wall of the air intake plate 311 via a support shaft. One end of the limiting rod 39 slides through the sliding sleeve 38. One end of the second spring 310 is fixedly mounted inside the sliding sleeve 38, and the other end of the second spring 310 is fixedly mounted on the limiting rod 39. The second spring 310 can provide the limiting rod 39 with the elastic force required for reset. The top of the air intake plate 311 slides against the bottom of the sliding block 34. The air intake plate 311 can change its angle and switch to different cooling modes under the drive of the sliding block 34.

[0055] One end of the driven magnet 301 is fixedly mounted on the side wall of the extrusion rod 33;

[0056] The active electromagnet 303 is located on the front of the driven magnet 301. The top of the active electromagnet 303 is fixedly installed at the bottom of the combined plate 32. After being energized, the active electromagnet 303 is magnetically attracted to the driven magnet 301, thereby driving the air duct 311 to change angle and switch to different cooling modes. One end of the spring 302 is fixedly installed on the extrusion rod 33, and the other end of the spring 302 is fixedly installed inside the combined plate 32. The spring 302 can provide elastic force for the extrusion rod 33 to reset.

[0057] In use, when the load of one or more circuit breakers in the circuit breaker group 12 is significantly higher than that of the other circuit breakers, the control panel 11 is activated to switch to precise heat dissipation and cooling mode two. By energizing the active electromagnet 303, the magnetism between the active electromagnet 303 and the driven magnet 301 becomes attractive. Under the action of the magnetic attraction, the driven magnet 301 drives the pressing rod 33 to move. Through the sliding cooperation between the pressing rod 33 and the combination plate 32, the pressing rod 33 can move under the action of the driven magnet 301. Figure 6 The circuit breaker group 12 slides on one side, and the inclined surface of the sliding block 34 is squeezed by the squeezing rod 33, so that the sliding block 34 drives the sliding plate 35 to move. The sliding plate 35 and the limiting post 36 slide together, so that the sliding plate 35 can move linearly along the limiting post 36 under the action of external force. At the same time, the air duct 311 provides support to the limiting post 36. The sliding block 34 squeezes the air duct 311 to move, so that the sliding block 34, the sliding plate 35, the limiting post 36, and the spring 37 rotate downward with the air duct 311 around the movable axis, so that some of the cold air flowing out of the air duct 2 can flow precisely to one or several circuit breakers with high load under the action of the air duct 311 for precise heat dissipation and cooling.

[0058] When the air-guiding plate 311 in the upper part of the air duct 2 flips downward under the action of external force, the air-guiding plate 311 will simultaneously drive one of the sliding sleeves 38 to move. The sliding sleeve 38 drives the limiting rod 39 to move. The limiting rod 39 drives the other sliding sleeve 38 to move synchronously. The other sliding sleeve 38 drives the air-guiding plate 311 in the lower part of the air duct 2 to flip downward synchronously. By guiding the air through the double-layer air-guiding plate 311, the air-guiding effect is improved. At the same time, the cross-sectional area of ​​the limiting rod 39 is smaller than that of the sliding sleeve 38, so that the limiting rod 39 can not only move vertically in the sliding sleeve 38, but also make a small range of back and forth swaying to adapt to the slight change in angle when the air-guiding plate 311 flips.

[0059] When it is not necessary to maintain the precise heat dissipation cooling mode 2, the active electromagnet 303 is de-energized via the control panel 11, causing the driven magnet 301 to reset under the action of the spring 302. Figure 9 As shown in the initial position, the sliding plate 35 is also reset to its original position under the action of the spring 37. Figure 9 As shown in the initial position, the limiting rod 39 and the sliding sleeve 38 are also reset to their original positions under the action of the second spring 310. Figure 9 The initial position shown;

[0060] If all circuit breaker groups 12 are under high load, switch to precise heat dissipation and cooling mode one. Instead of controlling the switching of the magnetic field of the active electromagnet 303 via control panel 11, directly control the start of the power push rod 3 via control panel 11. The power push rod 3 then drives the sliding rod 31 to move... Figure 6 When the circuit breaker assembly 12 moves to the side where it is located, the sliding rod 31 drives the combination plate 32 to move synchronously, and the combination plate 32 drives the spring 310 and the pressing rod 33 to move synchronously. Figure 6 The circuit breaker group 12 moves to one side, causing all the squeezing rods 33 to simultaneously squeeze the corresponding sliding block 34, causing the corresponding air duct 311 to flip and change its angle, guiding most of the cold air to the circuit breaker group 12 for cooling, until some or all of the circuit breaker group 12 is out of the high load state, and switches from precise heat dissipation cooling mode one to precise heat dissipation cooling mode two or normal heat dissipation cooling mode.

[0061] In both Precision Cooling Mode 1 and Precision Cooling Mode 2, the operating power of the cooling unit is adjusted based on the cooling results. If the cooling is sufficient to keep the circuit breaker group 12 within the optimal operating temperature range, the operating power of the cooling unit does not need to be changed. If the circuit breaker group cannot be kept within the optimal operating temperature range, the operating power of the cooling unit is changed.

[0062] Example 3, the technical solution of which differs from Example 2 includes: the back plate 13 is provided with a control component for changing the cooling mode and an auxiliary component for changing the cooling effect; the bottom of the fixed frame 4 is fixedly installed on the bottom of the inner wall of the air duct 2; the mounting shaft 41 is hinged in the fixed frame 4 by a torsion spring; the auxiliary plate 42 is fixedly installed on the mounting shaft 41; the bottom of the airbag 43 is fixedly installed on the bottom of the inner wall of the fixed frame 4, and the side wall of the airbag 43 slides against the side wall of the auxiliary plate 42; the pressure rod 44 is hinged in the fixed frame 4 by a rotating shaft and a worm spring; the side wall of the auxiliary magnet 45 is fixedly installed on one end of the pressure rod 44; one end of the adjusting electromagnet 46 is fixedly installed on the side wall of the wind baffle 21; after being energized, the adjusting electromagnet 46 is attracted to the magnetic field of the auxiliary magnet 45, thereby changing the cooling effect.

[0063] When in use, if the cooling requirements of the circuit breaker group are still not met after switching between Precision Cooling Mode 1 and Precision Cooling Mode 2, the air baffle 21 is already fully open. At this time, the adjusting electromagnet 46 moves upward with the air baffle 21 and is positioned above the auxiliary magnet 45. The adjusting electromagnet 46 is energized by the control panel 11, so that the adjusting electromagnet 46 and the auxiliary magnet 45 are magnetically attracted. Under the action of magnetic attraction, the auxiliary magnet 45 drives the pressure rod 44 to rotate synchronously around the rotation axis. The end of the pressure rod 44 near the auxiliary magnet 45 is upward and the other end is downward. The downward-moving pressure rod squeezes the airbag 43, causing the airbag 43 to expand to both sides.

[0064] The inflated airbag 43 squeezes the auxiliary plates 42 on both sides and flips outward from the fixed frame 4 with the mounting shaft 41 as the axis. The air duct 2 narrows, so that when the cold air flows through this place, the Bernoulli effect is triggered and the flow rate is increased.

[0065] If the cooling demand of the circuit breaker group 12 is still not met after accelerating the cooling air in this way, then the power of the cooling unit should be changed.

[0066] When it is not necessary to maintain the acceleration state, the control panel 11 can be used to de-energize the adjusting electromagnet 46, causing the pressure rod 44 to return to its original position under the action of the worm spring. Figure 12 As shown in the initial state, the auxiliary plate 42 also resets to its original position under the action of the torsion spring. Figure 12 As shown in the initial state, airbag 43 has also deflated, awaiting the next use.

[0067] This invention also provides a method for using intelligent energy-saving power distribution equipment for smart buildings, including the following steps:

[0068] S1. In normal cooling mode, the operation of the heat dissipation unit is controlled by the control panel 11 to ventilate and cool the circuit breaker group 12 in the power distribution cabinet 1.

[0069] S2. Monitor the temperature of circuit breaker group 12;

[0070] S3. Based on the monitoring results of step S2, if the circuit breaker group 12 has different heating levels in different lines due to different power demand in different zones of the building, the control panel 11 controls the control component to start and switch the cooling mode.

[0071] S4. If the cooling requirement cannot be met after switching the cooling mode, start the auxiliary component from control panel 11.

[0072] S5. If the cooling zone needs cannot be met after the auxiliary components are started, the operating power of the heat dissipation unit can be changed by the control panel 11.

[0073] After the cooling requirements of S6 and circuit breaker group 12 decrease and become almost the same, switch back to normal cooling mode.

[0074] The time required for the control component to switch cooling modes is between 1 and 3 seconds.
