Description

Technical Field

[0001] The present invention relates to the technical field of power distribution cabinet accessories, and in particular to an intelligent power-saving power distribution device for smart buildings and a method of using the same. Background Art

[0002] There are many types of intelligent, energy-saving power distribution equipment used in smart buildings, the most important of which is the power distribution cabinet. Current power distribution cabinets typically use a unified cooling strategy. If cooling is insufficient, the operating power of the heat dissipation unit is increased. This leads to differences in power usage between different functional areas within the building, which is reflected in the fact that some circuits within the power distribution cabinet are not adequately cooled. For example, Publication No. CN119171239B discloses a modular, high-performance power distribution cabinet. Although this application improves heat exchange capacity by providing liquid cooling components, the cooling effect of electrical equipment that comes into contact with the coolant first is significantly better than that of electrical equipment that comes into contact with the coolant later. Furthermore, cooling cannot be tailored to the heating conditions of different circuits.

[0003] A low-voltage distribution cabinet set disclosed in Publication No. CN118487146B can change the direction of airflow, but it requires the use of multiple motors working together, all of which are located inside the cabinet, adding a heat source. Whether the resulting cooling effect can offset the temperature increase caused by the additional heat source remains to be verified.

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

[0005] In view of the deficiencies in the prior art, the present invention provides an intelligent energy-saving power distribution device for smart buildings and a method of use, which solves the problems raised in the background art.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: an intelligent power-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 in the power distribution cabinet to control the power consumption status, and a back panel installed on the back of the power distribution cabinet. The back panel 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, one end of which is fixed in the power distribution cabinet, provides power for changing the cooling mode;

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

[0009] The sliding block, the top of which slides against the squeezing rod and moves downward under the squeezing of the squeezing rod;

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

[0011] Preferably, the regulating component also includes: a driven magnet, one end of which is fixed on the side wall of the extrusion rod; an active electromagnet, which is located in front of the driven magnet and is magnetically attracted to the driven magnet when energized, driving the air induced plate to change its angle and switch to different cooling modes.

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

[0013] Preferably, the regulating component also includes: a limit column, one end of which is fixed to the top of the air induced plate and the other end slides out from the sliding plate to limit the moving direction of the sliding plate; a spring, one end of which is fixed to the top of the air induced plate and the other end is fixed to the bottom of the sliding plate to provide a reset elastic force to the sliding plate.

[0014] Preferably, the regulating assembly also includes: a sliding sleeve, which is movably installed on the side wall of the air induced plate through 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 in the sliding sleeve and the other end is fixed on the limiting rod, providing the elastic force required for resetting the limiting rod.

[0015] Preferably, a cooling assembly is also provided on the back panel, and the cooling assembly includes: an air duct, one end of which is fixed on the back panel to guide the cold air to flow into the distribution cabinet; an air baffle, one end of which slides from the air duct into the distribution cabinet to change the passable cross-sectional area of ​​the air duct; a guide rod, one end of which is fixed in the air baffle and the other end of which slides through the back panel; an adjusting push rod, one end of which is fixed on the back panel through a mounting plate and the other end of which is fixed to the bottom of the guide rod to change the position of the air baffle.

[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 in the fixed frame through 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 is in sliding contact with the side wall of the auxiliary plate.

[0017] Preferably, the auxiliary component also includes: a pressure rod, which is hinged in the fixed frame through a rotating shaft and a spiral spring; an auxiliary magnet, the side wall of which is fixed on the pressure rod; and an adjusting electromagnet, one end of which is fixed on the side wall of the wind blocking plate, and is magnetically attracted to the auxiliary magnet when powered on to change the cooling effect.

[0018] The present invention also provides a method for using an intelligent power-saving power distribution device for a smart building, comprising the following steps:

[0019] S1, in normal cooling mode, the heat dissipation unit is controlled by the control panel to ventilate and cool the circuit breaker group in 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 different circuits in the circuit breaker group have different heating levels due to different power demands in different zones within the building, the control panel controls the control component to start and switch to the cooling mode;

[0022] S4. If the cooling demand is still not met after switching the cooling mode, the control panel activates the auxiliary component;

[0023] S5. If the auxiliary components still cannot meet the cooling zone demand after being started, the control panel will change the operating power of the cooling unit;

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

[0025] Preferably, the time required for the regulating component to switch the cooling mode is between 1-3 seconds.

[0026] The present invention provides an intelligent energy-saving power distribution device for smart buildings and its use method. Compared with the existing technology, it has the following advantages:

[0027] (1) The intelligent energy-saving power distribution equipment and its use method used in the smart building can detect the current size (reflecting the load status) borne by the circuit breaker group to determine the degree of heat inside the distribution cabinet, and adjust the area that can enter the air duct and the operating power of the heat dissipation unit accordingly, so as to avoid "full load operation" and waste electricity. When the load is low, the fan speed is reduced or the air inlet area is reduced to achieve energy-saving operation, reduce the frequent start and stop and high-load operation of the heat dissipation device, and improve the 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 the smart building no longer adopt the "overall air supply" mode, but instead accurately direct 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 the low-load area, saving energy, effectively preventing local overheating in the high-load area, and improving the operating stability of the equipment. When the power consumption of the building is unevenly distributed (such as high load in the office area during the day and high load in the lighting area at night), it can still maintain good heat dissipation performance, realize "tiered heat dissipation" control, and take into account both energy saving and safety.

[0029] (3) The intelligent energy-saving power distribution equipment and its use method used in the smart building introduce the Bernoulli effect in the air duct structure (i.e., through the variable cross-section design, the wind speed is accelerated in the narrow area), which can increase the wind speed and cooling efficiency without increasing the fan power, avoiding the energy waste caused by blindly increasing the fan power, and improving the cooling efficiency under unit energy consumption without increasing the additional heat dissipation demand. A three-level response mechanism is adopted, and each level of response corresponds to a different load state, avoiding the "one-step" high-energy consumption operation, improving the system robustness, adapting to different working conditions, extending the life of the heat dissipation equipment, and reducing the failure rate.

[0030] Other features and advantages of the present invention will be described in the following detailed description, and part of them will become obvious from the description or be understood by practicing the present invention. The purpose and other advantages of the present invention can be realized and obtained by the structures particularly pointed out in the written description and the accompanying drawings.

[0045] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0046] See also Figures 1 to 13 , the present invention provides the following technical solutions:

[0047] Example 1: An intelligent power-saving power distribution device for a smart building, comprising a power distribution cabinet 1 with a heat dissipation unit, a control panel 11 fixedly mounted on the front of the power distribution cabinet 1, a circuit breaker group 12 detachably mounted in the power distribution cabinet 1 for controlling power usage, and a back panel 13 detachably mounted on the back of the power distribution cabinet 1. A cooling assembly is provided on the back panel 13. The back panel 13 is provided with an air inlet and an air outlet, with the air inlet located above the air outlet. The cooling assembly includes:

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

[0049] When in use, the power supply to each area in the building is controlled by the circuit breaker group 12 in the power distribution cabinet 1, and the power supply share is determined according to the power demand in different areas of the building through the control panel 11. An air inlet is provided at the upper part of the back panel 13, and an air outlet is provided at the lower part of the back panel 13, and necessary dust and moisture-proof measures are installed on both sides. A wind blocker 21 is slidably installed in the air duct 2, and a guide rod 23 provides support for the wind blocker 21. The guide rod 23 and the back panel 13 are slidably engaged, and the back panel 13 provides support for the adjustment push rod 22, and the adjustment push rod 22 provides support for the guide rod 23.

[0050] When the overall electricity demand in the building decreases, the current flowing 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, so that the adjustment push rod 22 drives the guide rod 23 to move downward, and the guide rod 23 drives the wind blocking plate 21 to move downward, so that the passable area of ​​the air duct 2 is reduced, and the operating power of the heat dissipation unit is simultaneously reduced;

[0051] When the overall demand for electricity 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 at the same time, the adjustment push rod 22 is started to drive the guide rod 23 to move upward, so that after the wind blocking plate 21 moves upward, the passable area of ​​the air duct 2 increases.

[0052] Embodiment 2: This embodiment differs from Embodiment 1 in that a technical solution includes: a regulating component for changing the cooling mode is provided on the back plate 13, and the regulating component includes:

[0053] One end of the power push rod 3 is fixedly installed in the 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 extrusion rod 33. The combination plate 32 is used to provide support for the extrusion rod 33. The extrusion 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 extrusion rod 33. The sliding block 3 4 can move downward under the squeezing of the squeezing rod 33. One end of the sliding plate 35 is fixedly mounted 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 column 36 is fixedly mounted on the top of the air inducing plate 311. The other end of the limiting column 36 slides out of the sliding plate 35. The limiting column 36 is used to limit the moving direction of the sliding plate 35. One end of the spring 1 37 is fixedly mounted on the top of the air inducing plate 311. The other end of the spring 1 37 is fixedly mounted on the bottom of the sliding plate 35. The spring 1 37 can provide elastic force for returning the sliding plate 35.

[0054] The side wall of the sliding sleeve 38 is movably mounted on the side wall of the air induction 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 in 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 elastic force required for the limiting rod 39 to reset. The top of the air induction plate 311 slides against the bottom of the sliding block 34. Driven by the sliding block 34, the air induction plate 311 can change its angle to switch to different cooling modes.

[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 in front of the driven magnet 301, and the top of the active electromagnet 303 is fixedly mounted on the bottom of the combination plate 32. After being energized, the active electromagnet 303 is magnetically attracted to the driven magnet 301, thereby driving the air induced plate 311 to change its angle and switch to different cooling modes. One end of the spring three 302 is fixedly mounted on the extrusion rod 33, and the other end of the spring three 302 is fixedly mounted in the combination plate 32. The spring three 302 can provide elastic force for the extrusion rod 33 to reset.

[0057] During use, when the load of one or several circuit breakers in the circuit breaker group 12 is significantly higher than that of other circuit breakers, the control component is activated through the control panel 11 to switch to the precise heat dissipation cooling mode 2. By energizing the active electromagnet 303, the magnetism between the active electromagnet 303 and the driven magnet 301 becomes attracted to each other, so that the driven magnet 301 drives the extrusion rod 33 to move under the action of the magnetic attraction force. Through the sliding cooperation between the extrusion rod 33 and the combination plate 32, the extrusion rod 33 can be driven by the driven magnet 301 to move. Figure 6 When the circuit breaker group 12 is located on the side where the circuit breaker group 12 slides, the extrusion rod 33 squeezes the inclined surface of the sliding block 34, so that the sliding block 34 drives the sliding plate 35 to move. The sliding plate 35 and the limiting post 36 slide in cooperation, so that the sliding plate 35 can move linearly along the limiting post 36 under the action of an external force. At the same time, the air induction plate 311 provides a supporting force to the limiting post 36. The sliding block 34 synchronously squeezes the air induction plate 311 to move, so that the sliding block 34, the sliding plate 35, the limiting post 36, and the spring 1 37 rotate downward with the air induction plate 311 around the movable axis. Therefore, part of the cold air flowing out of the air duct 2 can be accurately directed to one or several circuit breakers with high loads under the action of the air induction plate 311 for accurate heat dissipation and cooling.

[0058] When the air induction plate 311 at the upper part of the air duct 2 flips downward under the action of external force, the air induction plate 311 will synchronously 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, and the other sliding sleeve 38 drives the air induction plate 311 at the lower part of the air duct 2 to flip downward synchronously. The double-layer air induction plate 311 guides the air induction effect at the same time, and 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 up and down in a straight line in the sliding sleeve 38, but also rock back and forth in a small range to adapt to the slight change in the angle of the air induction plate 311 when it flips.

[0059] When it is not necessary to maintain the precise heat dissipation cooling mode 2, the active electromagnet 303 is powered off by the control panel 11, so that the driven magnet 301 is reset to the position under the action of the spring 302. Figure 9 The sliding plate 35 is also reset to the initial position shown under the action of the spring 1 37. Figure 9 The initial position shown in FIG. 2 is reset to the initial position shown in FIG. 2 , and the limit rod 39 and the sliding sleeve 38 are also reset to the initial position under the action of the spring 2 310. Figure 9 Initial position shown;

[0060] If the circuit breaker group 12 is in a high load state, it switches to the precise heat dissipation cooling mode 1, and the power push rod 3 is directly controlled by the control panel 11 to start, and the power push rod 3 drives the sliding rod 31 to move to the Figure 6 When the circuit breaker group 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 2 310 and the extrusion rod 33 to move synchronously. Figure 6 When the side where the circuit breaker group 12 is located moves, all the squeezing rods 33 squeeze the corresponding sliding blocks 34 at the same time, causing the corresponding air guide plates 311 to flip and change their angles, thereby directing most of the cold air to the circuit breaker group 12 for cooling, until some or all of the circuit breaker group 12 are no longer in the high-load state, and the system switches from precise heat dissipation cooling mode 1 to precise heat dissipation cooling mode 2 or normal heat dissipation cooling mode.

[0061] In the precise heat dissipation cooling mode 1 and the precise heat dissipation cooling mode 2, whether to change the operating power of the heat dissipation unit is determined based on the cooling result. If it is sufficient to keep the circuit breaker group 12 within the optimal operating temperature range, there is no need to change the operating power of the heat dissipation unit. If it is not possible to keep the circuit breaker group within the optimal operating temperature range, the operating power of the heat dissipation unit is changed.

[0062] Embodiment 3. The technical solution of this embodiment is different from that of embodiment 2 and includes: a control component for changing the cooling mode and an auxiliary component for changing the cooling effect are provided on the back plate 13; 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 through 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 through a rotating shaft and a spiral 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 blocking plate 21; the adjusting electromagnet 46 is magnetically attracted to the auxiliary magnet 45 after power is turned on, thereby changing the cooling effect.

[0063] During use, when the heat dissipation and cooling requirements of the circuit breaker group cannot be met after switching between the precise heat dissipation and cooling mode 1 and the precise heat dissipation and cooling mode 2, the air choke plate 21 is already in the fully open state. At this time, the adjusting electromagnet 46 is above the auxiliary magnet 45 as the air choke plate 21 moves upward. The adjusting electromagnet 46 is energized by controlling the control panel 11, so that after the adjusting electromagnet 46 is energized, there is magnetic attraction between the adjusting electromagnet 46 and the auxiliary magnet 45. As a result, the auxiliary magnet 45 drives the pressure rod 44 to turn and reverse synchronously around the rotation axis under the action of the magnetic attraction force, so that the end of the pressure rod 44 close to the auxiliary magnet 45 is upward and the other end is downward. The downward moving pressure rod squeezes the air bag 43, causing the air bag 43 to expand to both sides.

[0064] The inflated airbag 43 squeezes the auxiliary plates 42 on both sides and simultaneously turns them toward the outside of the fixed frame 4 with the mounting axis 41 as the axis. The air duct 2 narrows, so that when the cold air flows through this area, the Bernoulli effect is triggered and the flow speed is accelerated.

[0065] If the cooling air cannot be accelerated by this method to meet the heat dissipation and cooling requirements of the circuit breaker group 12, the power of the heat dissipation unit is changed;

[0066] When the acceleration state is no longer required, the control panel 11 is used to control the electromagnet 46 to be de-energized, so that the pressure rod 44 is reset to the position under the action of the spiral spring. Figure 12 In the initial state shown, the auxiliary plate 42 is also reset to Figure 12 In the initial state shown, the airbag 43 is also deflated, waiting for the next use.

[0067] An embodiment of the present invention further provides a method for using an intelligent power-saving power distribution device for a smart building, comprising the following steps:

[0068] S1, in normal cooling mode, 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 the circuit breaker group 12;

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

[0071] S4. If the cooling demand is still not met after switching the cooling mode, the control panel 11 starts the auxiliary component;

[0072] S5. If the auxiliary components still cannot meet the cooling zone demand after being started, the control panel 11 changes the operating power of the cooling unit;

[0073] S6. After the cooling demand of the circuit breaker group 12 decreases and becomes almost the same, the system switches back to the normal cooling mode.

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

[0075] At the same time, the contents not described in detail in this specification belong to the existing technology well known to those skilled in the art.
