Description

Technical Field

[0001] This invention relates to the technical field of power distribution equipment, and in particular to an intelligent power distribution cabinet that integrates environmental monitoring and wind power regulation. Background Technology

[0002] Distribution cabinets are crucial equipment in power systems for power distribution, control, measurement, and protection, and are widely used in industrial, building, and municipal facilities. During operation, the electronic components inside the distribution cabinet, such as circuit breakers, contactors, and frequency converters, generate a significant amount of heat. If this heat cannot be dissipated in time, it can lead to excessively high temperatures inside the cabinet, accelerating component aging and even causing fires or short-circuit faults. Therefore, good heat dissipation performance is a critical design consideration for distribution cabinets.

[0003] Existing heat dissipation methods for electrical distribution cabinets mainly include natural ventilation and forced air cooling: Natural ventilation typically involves creating louvers or ventilation holes on the side walls or top of the cabinet to dissipate heat through the convection of hot and cold air. This method is simple in structure, but its heat dissipation efficiency is low, and the open ventilation holes can easily allow rainwater, dust, or insects to enter the cabinet, affecting electrical safety.

[0004] Forced air cooling involves installing cooling fans on the cabinet. Traditional forced air-cooled distribution cabinets typically have fixed air inlets and outlets. Even when the fans are not operating, these fixed vents remain open to the outside, failing to prevent moisture and dust from entering. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is: the fixed opening of the air inlet and outlet of the existing forced air-cooled power distribution cabinet, which makes it impossible to effectively block rainwater and dust from entering when the fan stops working.

[0006] The above-mentioned technical problems are solved by the following technical solution: This invention proposes an intelligent power distribution cabinet integrating environmental monitoring and wind-driven regulation, comprising a cabinet body, a lifting platform, and a sliding seal disposed inside the cabinet body, dividing the cabinet body into a first cavity and a second cavity; the first cavity is used to house electronic components; a fan is installed on the lifting platform for blowing air into the first cavity; an opening and closing assembly is disposed on the top of the cabinet body and is driven to connect with the lifting platform; the lifting platform can be driven to rise and fall according to the air pressure change of the first cavity, thereby driving the opening and closing assembly to open and close.

[0007] In a preferred embodiment of the intelligent power distribution cabinet integrating environmental monitoring and wind-driven regulation described in this invention: the opening and closing assembly includes a rain shield and a linkage assembly; the linkage assembly includes a first linkage, a second linkage, and a pair of sector gears; the sector gears are rotatably connected to the inner wall of the second cavity; the lifting platform is connected to the sector gears through the first linkage, converting the linear motion of the lifting platform into the rotational motion of the sector gears; the sector gears are hinged to the rain shield through the second linkage.

[0008] In a preferred embodiment of the intelligent power distribution cabinet integrating environmental monitoring and wind-driven regulation described in this invention: it further includes an adjustment component disposed on the side wall of the main body of the cabinet, a sensing component disposed below the fan, and a sliding rod assembly disposed between the adjustment component and the sensing component; the displacement generated by the sensing component under wind power is transmitted to the adjustment component through the sliding rod assembly.

[0009] In a preferred embodiment of the intelligent power distribution cabinet integrating environmental monitoring and wind power regulation described in this invention: the sensing component includes a telescopic cylinder fixed below the fan, a sliding block slidably disposed within the telescopic cylinder, and a compression spring disposed below the sliding block.

[0010] In a preferred embodiment of the intelligent power distribution cabinet integrating environmental monitoring and wind power regulation described in this invention: the sliding rod group includes a first sliding rod and a second sliding rod; the lateral sliding of the first sliding rod can drive the second sliding rod to move vertically.

[0011] In a preferred embodiment of the intelligent power distribution cabinet integrating environmental monitoring and wind regulation according to the present invention: the regulating component includes a ventilation opening opened on the side wall of the main body of the cabinet, and a wind deflector block disposed at the end of the second sliding rod; the wind deflector block moves with the movement of the second sliding rod, thereby changing the shading area of ​​the ventilation opening.

[0012] In a preferred embodiment of the intelligent power distribution cabinet integrating environmental monitoring and wind regulation described in this invention: the rain shield includes a sealing structure between the first baffle and the second baffle to prevent rainwater from entering.

[0013] In a preferred embodiment of the intelligent power distribution cabinet integrating environmental monitoring and wind power regulation described in this invention: a sealing ring is provided between the lifting platform and the inner wall of the cabinet body, so that the first cavity can form a high-pressure environment relative to the outside when the fan is working.

[0014] In a preferred embodiment of the intelligent power distribution cabinet integrating environmental monitoring and wind power regulation described in this invention: a filter shell is provided on the outside of the fan.

[0015] In a preferred embodiment of the intelligent power distribution cabinet integrating environmental monitoring and wind power regulation described in this invention: the filter housing is detachably disposed on the outside of the fan.

[0016] The beneficial effects of this invention are as follows: By setting up a lifting platform and a wind-driven component, this invention utilizes the pressure difference in the first cavity generated when the fan is working and the air force at the air outlet as a power source, and achieves automatic synchronous opening and closing of the top opening and closing component and the side adjustment component of the cabinet with the start and stop of the fan without the need for an additional motor drive device. This design not only effectively solves the problem that the fixed air vents of traditional power distribution cabinets cannot prevent rainwater and dust from entering when not in operation, thus improving the protection level of the cabinet, but also avoids the defects of existing electric opening and closing mechanisms, such as high cost and susceptibility to environmental influences leading to failure.

Detailed Implementation

[0018] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0019] The terminology used in this invention is that which is currently widely used in the art in consideration of the function of the invention; however, these terms may vary according to the intent of those skilled in the art, precedent, or new technology in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the invention. Therefore, the terms used in this specification should not be construed as simple names, but rather based on their meanings and the overall description of the invention.

[0020] Example 1 Reference Figure 1-4This embodiment provides an intelligent power distribution cabinet integrating environmental monitoring and wind power regulation, including a cabinet body 1, a lifting platform 2, and a sliding seal disposed inside the cabinet body 1, dividing the cabinet body 1 into a first cavity 3 and a second cavity 4. The first cavity 3 is used to house electronic components. A fan 5, mounted on the lifting platform 2, is used to blow air into the first cavity 3. An opening and closing assembly 6 is disposed on the top of the cabinet body 1 and is driven to connect with the lifting platform 2. The lifting platform 2 can be driven to rise and fall according to the air pressure change in the first cavity 3, thereby driving the opening and closing assembly 6 to open and close. Specifically, the first cavity 3 is designed as a pressurized cavity with good airtightness. When the temperature sensor in the first cavity 3 detects that the electronic components are heating up and the temperature exceeds a preset threshold, the control unit starts the fan 5 to continuously blow air into the first cavity 3. Since the air outlet velocity of the first cavity 3 is less than the air inlet velocity, the air pressure in the cavity rises rapidly, and the resulting pressure difference acts on the lower surface of the lifting platform 2, generating an upward thrust. When the thrust is greater than the sum of the weight and friction of the lifting platform 2 and the components above it, the lifting platform 2 slides vertically upward along the inner wall of the cabinet, thus providing the driving force for the opening and closing action of the top.

[0021] The opening and closing assembly 6 includes a rain shield 61 and a connecting rod assembly 62. The connecting rod assembly 62 includes a first connecting rod 622, a second connecting rod 623, and a pair of sector gears 621. The sector gears 621 are rotatably connected to the inner wall of the second cavity 4. The lifting platform 2 and the sector gears 621 are connected through the first connecting rod 622, converting the linear motion of the lifting platform 2 into the rotational motion of the sector gears 621. The sector gears 621 are hinged to the rain shield 61 through the second connecting rod 623. In this embodiment, when the lifting platform 2 moves upward under air pressure, it drives the sector gears 621 to rotate, and the rocker arm end of the sector gears 621 swings outward and upward, opening the originally horizontally covered rain shield 61 to both sides through the connecting rod. Utilizing the lever principle, a small displacement of the platform driven by air pressure can be converted into a large opening angle of the rain shield 61, which is conducive to rapid heat dissipation.

[0022] It also includes an adjustment component 7 installed on the side wall of the main body 1, a sensing component 8 installed below the fan 5, and a sliding rod assembly 9 installed between the adjustment component 7 and the sensing component 8; the displacement generated by the sensing component 8 under wind power is transmitted to the adjustment component 7 through the sliding rod assembly 9. The sensing component 8 is located directly below the air outlet of the fan 5 in the airflow path. The faster the fan 5 rotates, the greater the force of the wind impacting the sensing component 8, and the greater the mechanical displacement generated. This, in turn, controls the side wall adjustment component 7 to open a larger ventilation area through the sliding rod assembly 9, achieving adaptive matching between the air intake volume and the fan 5 rotation speed, and maintaining the dynamic balance of airflow inside and outside the cabinet.

[0023] The sensing component 8 includes a telescopic cylinder 81 fixed below the fan 5, a sliding block 82 slidably disposed within the telescopic cylinder 81, and a compression spring 83 disposed below the sliding block 82. The top surface of the sliding block 82 is designed to be the wind-receiving surface. When the fan 5 is stationary, the spring force of the compression spring 83 lifts the sliding block 82 to its initial position at the top of the telescopic cylinder 81. When the fan 5 starts, the high-speed airflow vertically impacts the top surface of the sliding block 82, applying downward pressure. When the wind force exceeds the supporting force of the compression spring 83, the sliding block 82 overcomes the spring resistance and slides downward along the telescopic cylinder 81. The stronger the wind, the shorter the spring is compressed, and the longer the sliding block 82 descends.

[0024] The sliding rod assembly 9 includes a first sliding rod 91 and a second sliding rod 92; the lateral sliding of the first sliding rod 91 drives the second sliding rod 92 to move vertically. To achieve the conversion of the motion direction, the side wall of the sliding block 82 is provided with a first inclined surface or a wedge-shaped protrusion, and the end of the first sliding rod 91 is provided with a mating contact surface. When the sliding block 82 moves downward, the inclined surface of its side wall presses against the end of the first sliding rod 91, forcing the first sliding rod 91 to move laterally outward. Similarly, the connection between the first sliding rod 91 and the second sliding rod 92 is also provided with a similar inclined surface mating structure or a linkage conversion mechanism, converting the horizontal thrust of the first sliding rod 91 into the vertical upward or downward lifting motion of the second sliding rod 92, thereby realizing the complex transmission from "linear motion below the fan 5" to "linear motion of the side wall".

[0025] The adjustment component 7 includes a vent 71 on the side wall of the cabinet body 1 and a wind deflector 72 at the end of the second slide rod 92. The wind deflector 72 moves with the movement of the second slide rod 92, thereby changing the area of ​​the vent 71 it covers. The vent 71 is a louvered or grid-like opening. The wind deflector 72 slides against the inner side wall of the cabinet. In the initial state when there is no wind, the wind deflector 72 completely covers the vent 71, ensuring the cabinet is sealed. When the second slide rod 92 is driven to move, it moves the wind deflector 72 away, exposing the vent 71. If the fan 5 is running at full speed, the wind deflector 72 moves to its limit position, the vent 71 is fully opened, and outside cold air quickly enters the first cavity 3 through the vent 71 under negative pressure, forming an efficient heat dissipation convection channel.

[0026] The rain shield 61 includes a sealing structure between a first baffle 611 and a second baffle 612 to prevent rainwater from entering. The contact edges of the first baffle 611 and the second baffle 612 feature a stepped overlapping design, with EPDM EPDM rubber sealing strips or silicone sealing gaskets adhered to the overlapping surfaces. When the lifting platform 2 resets, causing the baffle to close, gravity causes the two baffles to press tightly together, and the sealing strip elastically deforms to fill the gaps, effectively preventing rainwater and dew from seeping into the cabinet interior through the top cover gaps.

[0027] A sealing ring is provided between the lifting platform 2 and the inner wall of the cabinet body 1, enabling the first cavity 3 to form a high-pressure environment relative to the outside when the fan 5 is operating. The sealing ring is preferably made of a wear-resistant material with a low coefficient of friction, such as a polytetrafluoroethylene (PTFE) composite rubber ring, and is embedded in a groove on the periphery of the lifting platform 2. This sealing ring must ensure airtightness to maintain the air pressure difference required for driving the lifting, and also ensure the smoothness of the lifting platform 2 during movement, preventing the platform from jamming due to excessive frictional resistance. Furthermore, a lubricating coating can be applied to the inner wall of the cabinet to further assist in sealing and sliding.

[0028] A filter housing 10 is installed on the outside of the fan 5. The filter housing 10 is mesh-like and filled with activated carbon fiber cotton or metal dustproof mesh. Its function is twofold: firstly, to prevent installation and maintenance personnel from accidentally touching the high-speed rotating fan blades; and secondly, to pre-filter the intake or recirculated air, adsorbing large particles of dust and lint in the air, preventing them from accumulating in the telescopic cylinder 81 of the sensing component 8 and affecting the sensitivity of the sliding block 82, or accumulating on the surface of electronic components and affecting heat dissipation.

[0029] The filter housing 10 is detachably mounted on the outside of the fan 5. For easy daily cleaning and filter replacement, the filter housing 10 is secured to the fan 5 frame via snap-fit ​​connections, magnetic connections, or hand-tightened screws. Maintenance personnel can remove the filter housing 10 by hand without the need for complex tools, clean off accumulated dust, and reinstall it, ensuring long-term ease of maintenance for the equipment.

[0030] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of the present invention.
