Description

Technical Field

[0001] The present invention relates to the technical field of power supply cabinets, and more particularly to an integrated micro-station power supply cabinet. Background Art

[0002] With the rapid development of industrial automation, communication networks, and data centers, power supply cabinets, as core equipment in power systems, must ensure stable power supply under harsh operating conditions such as high loads and complex environments. However, the problem of internal temperature rise is becoming increasingly prominent due to nonlinear temperature changes (such as ambient temperature fluctuations, sudden load changes, and differences in component heating characteristics), becoming a key factor restricting equipment reliability and energy efficiency.

[0003] Currently, power cabinets generally use fixed cooling solutions (such as fans and heat sinks). Although these solutions can achieve basic temperature control, they have significant drawbacks: Insufficient dynamic adjustment capability: Traditional cooling modes cannot respond to the nonlinear characteristics of temperature changes in real time, resulting in a mismatch between cooling intensity and temperature rise requirements. For example, high-power cooling is maintained in low-load or low-temperature environments, resulting in energy waste. However, under high load or sudden temperature rise, the delayed cooling may lead to the risk of local overheating.

[0004] Poor system coordination: Existing technologies mostly rely on a single heat dissipation mechanism. For example, patent CN117424083B optimizes the heat dissipation path through a heat dissipation cleaning component and a secondary heat dissipation lighting module. Although this improves the heat dissipation efficiency, it does not solve the problem of uneven temperature field distribution, making it difficult to implement differentiated regulation for local hot spots.

[0005] Low energy efficiency and economy: A constant heat dissipation strategy cannot take into account both temperature control and energy saving requirements. Especially in scenarios with multiple coupling factors (such as high temperature and humidity, and areas with dense cables), excessive or insufficient heat dissipation can easily lead to increased operating costs and shortened equipment life.

[0006] Although some improvement solutions have improved heat dissipation efficiency through structural optimization (such as modular heat dissipation design and cable layout management), they are still limited to passive response mechanisms and lack the ability to intelligently perceive and dynamically control temperature changes. Therefore, there is an urgent need for an adaptive heat dissipation system driven by real-time temperature data. Through multi-parameter collaborative analysis and multi-mode heat dissipation strategy switching, precise temperature control and energy consumption optimization can be achieved to meet the high reliability and high economy operation requirements of power cabinets in complex application scenarios.

A bellows with a telescopic function is installed on the rear side wall of the sealing cover. The two bellows, arranged upper and lower, penetrate the rear side wall of the cabinet and are respectively connected to the exhaust end and return end of the circulating cooling system to form a complete circulating cooling circuit. The cross guide frame is provided with a cross guide system consisting of a long branch guide groove and a short branch guide groove, which is in a "Y" shape. The guide rods of the cooling mechanism and the side wall of the self-sealing door form a sliding fit with the short branch guide groove and the long branch guide groove respectively.

[0009] Furthermore, the cooling mechanism and the left and right side walls of the self-sealing door are provided with fixedly connected guide rods, wherein the guide rods of the self-sealing door are fixedly installed at the top positions of the left and right side walls, while the guide rods of the cooling mechanism are fixedly installed at the lower rear positions of the left and right side walls.

[0010] Furthermore, the two guide grooves are arranged at an angle and have an intersection node; the inclination angle of the short branch guide groove is greater than that of the long branch guide groove; the side wall of the cross guide frame is rigidly connected with a slide that does not participate in the cross guide system, and the slide is precisely embedded in the slide rail and forms a stable sliding fit relationship with it.

[0011] Furthermore, when the self-sealing door is in the extreme position of radial expansion movement, its end near the core component loading compartment can still be embedded in the sockets on the front sides of the upper and lower walls of the component; a limit plate is fixedly provided on the front side of the connecting angle plate, and the limit plate is tightly attached to the rear side wall of the sealing cover.

[0012] Furthermore, two upper and lower windows are provided on the rear side wall of the cabinet, and the windows on the rear side wall of the cabinet are arranged in the radially outer area of ​​the grid, thereby forming a continuous air flow channel.

[0013] Furthermore, two groups of hanging and retracting mechanisms installed on the side walls of the cabinet are symmetrically arranged behind the core component loading compartment, and each group of hanging and retracting mechanisms is composed of a double-track base, a rocker arm, a rotating shaft and a hinge seat: the double-track base is rigidly fixed to the rear wall of the cabinet, and the rocker arm is arranged in a cross shape on the front side of the double-track base, and the middle part is hinged by a rotating shaft; one group of ends of the cross-shaped rocker arm is hinged to the preset rail groove of the double-track base through the hinge seat, and the other group of ends is hinged to the connecting angle plate through the hinge seat.

[0014] Furthermore, the cooling mechanism includes a variable joint assembled on the side of the sealing cover away from the core component loading compartment, the variable joint is composed of a leakage groove, a soluble film layer and a buckle, wherein the leakage groove is rigidly connected to the sealing cover, the inside of the leakage groove is filled with a soluble film layer, and the buckle is crimped to the surface of the soluble film layer and fixed to the inside of the leakage groove in a detachable manner; a diversion nozzle is assembled in the sealing cover.

[0015] Furthermore, the top and bottom of the front compartment of the cabinet are respectively fixedly equipped with a water supply part and a floor drain, wherein the water supply part is connected to the high-pressure water system through a pipeline, and the water supply part adopts a combination of a drain pipe and a solenoid valve.

[0016] Furthermore, the rear side wall of the core component loading compartment is provided with a wire outlet constraint part including a partition bar, a wire outlet hole, an adjusting screw, a baffle, a spring and an insulating cutter, wherein the partition bar can be slidably assembled in the interlayer groove of the rear side wall of the compartment body, and the wire outlet holes opened on its surface are for the component lines inside the compartment body to pass through and realize electrical connection with the external power supply line; the front and rear sides of the middle part of the partition bar are rigidly connected to the baffle, and the adjusting screw is threaded through the positioning seat on the rear wall of the compartment body to form a rotational connection with the side wall of the baffle.

[0017] Furthermore, the interior of the partition bar is divided into two sections, one section forms a cavity, and the other section is slidably equipped with an insulating cutter. The insulating cutter is connected to the baffle through a side pull handle via a spring, and a punching device is provided on the side of the side pull handle away from the spring.

[0018] Technical effects and advantages of the present invention: 1. This invention achieves efficient switching between natural ventilation mode and enhanced heat dissipation mode through the synergistic effect of the cross-guide frame's cross-guide system. In natural ventilation mode, the radial expansion of the self-sealing hatch and the cooling mechanism creates a continuous airflow channel within the cabin, reducing energy consumption through passive heat dissipation. When the temperature exceeds the limit, the cross-guide frame drives the cooling mechanism and the self-sealing hatch to radially contract, forming a sealed cabin cavity. The circulating cooling system achieves forced convection heat exchange through a dual-channel cooling circuit of bellows and a sealed cover, achieving a cooling medium utilization rate exceeding 92%. This design combines energy conservation with efficient heat dissipation, and the switching process is precisely controllable.

[0019] 2. This system has fire handling capabilities. When the cabinet detects excessive smoke inside the cabin, it automatically triggers a hazard-free mode. First, an insulating cutter cuts the wire outlet to achieve electrical isolation. Simultaneously, a cross-guide frame drives the self-sealing hatch and cooling mechanism to complete an emergency lock, creating a fireproof seal. The cooling mechanism, self-sealing hatch, and core component loading compartment then move forward as a whole. The swing arm deploys to transport the sealed unit to the floor drain fire extinguishing station. Once the solenoid valve in the water supply unit is opened, water flows through the variable joint, dissolving the soluble film layer and activating the drain slot. Three-dimensional spraying extinguishes the fire through the sealing cover. The system responds rapidly, completing the entire process from detection to fire extinguishing within seconds, significantly improving fire emergency response capabilities.

DETAILED DESCRIPTION

[0033] The technical solutions of the present invention will be described clearly and completely below in conjunction with the drawings in the present invention. In addition, the forms of the various structures described in the following embodiments are merely examples. The integrated micro-station power cabinet involved in the present invention is not limited to the various structures described in the following embodiments. All other implementations obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0034] Reference Figure 1-Figure 2 、 Figure 4 The present invention provides an integrated micro-station power supply cabinet, comprising a cabinet body 1. The inner cavity of the cabinet body 1 is provided with a core component loading compartment 3. Two sets of cooling mechanisms 4 and two sets of self-sealing doors 5 are symmetrically arranged on the upper and lower sides of the core component loading compartment 3. The cooling mechanisms 4 and the left and right sides of the self-sealing doors 5 are both connected by a cross guide frame 6 for transmission. The cross guide frame 6 is rigidly connected to the slide rail 7 of the inner wall of the cabinet body 1 to form an axial sliding fit, and the left and right sets of cross guide frames 6 at the same height are assembled and connected by a connecting beam 8. It should be noted that in this embodiment, a hatch structure is hingedly mounted on the front side of the cabinet 1; at the same time, two upper and lower windows are provided on the rear side wall of the cabinet 1. This design not only ensures effective natural ventilation inside the cabinet 1, but also reserves sufficient space for the movement trajectory of the cross guide frame 6, thereby completely avoiding interference during the movement of the mechanism. In this article, all the positional relationships we discuss about front, back, left, and right are based on Figure 1-Figure 2These directions are defined by the perspective presented. They have no actual geographical or physical meaning. They are merely a reference framework to help readers understand the content of the article more intuitively. In this way, we can more clearly show the relative position relationship between the various parts, making the entire discussion process easier to understand and follow. Please note that this custom direction identification is only for internal use in this article and does not represent any absolute direction or position in the real world.

[0035] Reference Figure 2-Figure 3 、 Figure 5-Figure 7 The core component loading compartment 3 is composed of a compartment 301, a connecting angle plate 302, a grid 303 and a wire-outlet restraint 304. Two sets of connecting angle plates 302 are symmetrically arranged on the rear side of the top and bottom walls of the compartment 301 in a rigid connection manner, and a socket for the self-sealing door 5 to pass through is provided on the front side. The grid 303 is installed in the top and bottom wall areas of the compartment 301 between the connecting angle plates 302 and the sockets. The compartment 301 adopts an open front structural design to facilitate the installation of internal components. At the same time, the wire-outlet restraint 304 is fixedly installed on the rear side wall. The cooling mechanism 4 consists of a sealing cover 401 and a bellows 402. The sealing cover 401 is aligned with the grid 303, and the coverage of the sealing cover 401 at least completely covers the grid 303. A bellows 402 with a telescopic function is installed on the rear side wall of the sealing cover 401. The two bellows 402 arranged above and below pass through the rear side wall of the cabinet 1 and are respectively connected to the exhaust and return ends of the circulating cooling system, thereby forming a complete circulating cooling circuit. The left and right side walls of the cooling mechanism 4 and the self-sealing hatch 5 are both provided with guide rods fixedly connected. The guide rods of the self-sealing hatch 5 are fixedly mounted at the top positions of the left and right side walls, while the guide rods of the cooling mechanism 4 are fixedly mounted at the lower rear positions of the left and right side walls. The cross guide frame 6 is provided with a cross guide system consisting of a long branch guide groove and a short branch guide groove, which is approximately "y"-shaped; the two guide grooves are arranged at an angle and have an intersection node; the guide rods on the side walls of the cooling mechanism 4 and the self-sealing door 5 respectively form a sliding fit with the short branch guide groove and the long branch guide groove. Since the inclination angle of the short branch guide groove is greater than that of the long branch guide groove, the cooling mechanism 4 and the self-sealing door 5 produce differentiated longitudinal displacements when the cross guide frame 6 slides horizontally, wherein the displacement of the cooling mechanism 4 is smaller than that of the self-sealing door 5; when the cooling mechanism 4 forms an airtight fit with the grid 303 on the top and bottom walls of the cabin 301 and the self-sealing door 5 is mechanically locked through the upper and lower symmetrical sockets, the guide rod of the cooling mechanism 4 is at the end of the short branch guide groove close to the core component loading cabin 3; and when the cooling mechanism 4 and the self-sealing door 5 reach the maximum centrifugal displacement driven by the cross guide system, the guide rod of the cooling mechanism 4 moves to the intersection node position of the short branch guide groove and the long branch guide groove.

[0036] It should be noted that in this embodiment, when the self-sealing hatch 5 is at the extreme position of radial expansion movement, its end near the core component loading compartment 3 can still be inserted into the sockets on the front sides of the upper and lower walls of the component; The windows on the rear side wall of the cabinet 1 are arranged in the radially outer area of ​​the grid 303, thereby forming a continuous air flow channel (i.e., a natural ventilation channel); A limit plate is fixedly provided on the front side of the connecting angle plate 302. The limit plate is tightly attached to the rear side wall of the sealing cover 401, and achieves auxiliary limiting of the cooling mechanism 4 through surface contact. Since the cooling mechanism 4 forms a sliding fit with the short branch guide groove of the cross guide frame 6 only through the guide rods provided on its side wall, there is a technical defect of insufficient lateral constraint when it is lifted and lowered under the guidance of the cross guide frame 6, which is prone to unexpected shaking. By adding a limit plate on the front side of the connecting angle plate 302, the structural improvement can effectively eliminate the lateral degree of freedom of the cooling mechanism 4 during movement, significantly improving the movement stability of the mechanism. A push-pull device is disposed at the rear of the connecting beam 8, the output end of which is assembled and connected to the connecting beam 8. The push-pull device preferably adopts a telescopic cylinder structure, specifically including a hydraulic cylinder, a pneumatic cylinder or an electric push rod. Other equivalent push-pull devices that can achieve the horizontal reciprocating movement adjustment function of the connecting beam 8 can also be used as an alternative. A temperature monitoring system, such as a temperature sensor, is provided inside the cabin 301 to detect the operating temperature of the equipment in real time; The side wall of the cross guide frame 6 is rigidly connected with a slide that does not participate in the cross guide system. The slide is precisely embedded in the slide rail 7 and forms a stable sliding fit relationship with it.

[0037] Reference Figure 2 、 Figure 4-12, two groups of hanging and retracting mechanisms 2 installed on the side wall of the cabinet 1 are symmetrically arranged behind the core component loading compartment 3, and each group of hanging and retracting mechanisms 2 is composed of a double-track base 201, a rocker arm 202, a rotating shaft 203 and a hinge seat 204: the double-track base 201 is rigidly fixed to the rear side wall of the cabinet 1, and the rocker arm 202 is arranged in a cross shape on the front side of the double-track base 201, and the middle part is hinged by the rotating shaft 203; one group of ends of the cross-shaped rocker arm 202 is hinged to the preset track groove of the double-track base 201 through the hinge seat 204, and the other group of ends is hinged to the connecting angle plate 302 through the hinge seat 204; it should be noted that the hinge seat 204 located in the track groove of the double-track base 201 adopts a sliding fit, while the hinge seat 204 connected to the connecting angle plate 302 is a fixed installation structure; The cooling mechanism 4 further includes a variable joint 403 mounted on the side of the sealing cover 401 away from the core component loading compartment 3. The variable joint 403 consists of a leakage groove 4031, a soluble film layer 4032, and a retaining ring 4033. The leakage groove 4031 is rigidly connected to the sealing cover 401, the interior of the leakage groove 4031 is filled with the soluble film layer 4032, and the retaining ring 4033 is pressed against the surface of the soluble film layer 4032 and is detachably fixed to the interior of the leakage groove 4031. A diverter nozzle is mounted inside the sealing cover 401. The top and bottom of the front compartment of the cabinet body 1 are fixedly equipped with a water supply part 9 and a floor drain 10, respectively. The water supply part 9 is connected to the high-pressure water system through a pipeline. The water supply part 9 adopts a combination of a drain pipe and a solenoid valve; the variable joint 403 can move along the set trajectory and achieve alignment with the water supply part 9.

[0038] It should be noted that in this embodiment, an independent control system is configured outside the cabin 301. The power supply circuits for the temperature monitoring system, smoke monitoring system, displacement sensing system, control system, push-pull device, and solenoid valve all adopt an independent circuit design that is completely isolated from the power supply circuits of the components inside the cabin 301. This dual-circuit architecture ensures that if a fire occurs inside the cabin 301 and causes the main power supply circuit to be disconnected, the electric drive components independent of the cabin 301 can still maintain normal operation through the backup power supply circuit, thereby ensuring that the self-rescue function of the equipment in an emergency can be reliably executed. The soluble film layer 4032 uses a fixed ammonium nitrate filling layer as its core structure, and its upper and lower surfaces are coated with ammonium nitrate crystal film layers. This structural design ensures that the leakage channel 4031 can be reliably blocked under normal conditions, thereby ensuring that the sealing cover 401 remains completely sealed. When the system triggers the fire extinguishing water supply, the water flows through the variable joint 403 and quickly dissolves the soluble film layer 4032, causing the leakage channel 4031 to open, and the water flow is immediately injected into the interior of the cabin 301. At the same time, the soluble film layer 4032 in the bottom variable joint 403 opens the channel through the same dissolution mechanism, and the water finally flows smoothly out of the cabinet 1 through the floor drain 10. The rear side wall of the core component loading compartment 3 is provided with a wire outlet constraint portion 304, including a spacer 3041, a wire outlet hole 3042, an adjusting screw 3043, a baffle 3044, a spring 3045 and an insulating cutter 3046, wherein the spacer 3041 can be slidably assembled in the interlayer groove of the rear side wall of the compartment body 301, and the wire outlet hole 3042 opened on its surface is for the component lines inside the compartment body 301 to pass through and realize electrical connection with the external power supply line; the front and rear sides of the middle part of the spacer 3041 are rigidly connected to the baffle 3044, and the adjusting screw 3043 is threaded through the positioning seat on the rear wall of the compartment body 301 to form a rotational connection with the side wall of the baffle 3044. By adjusting the screwing amount of the adjusting screw 3043, the position of the wire outlet hole 3042 can be accurately controlled to adjust the direction of the wire harness; The interior of the partition bar 3041 is divided into two sections, one section forms a cavity, and the other section is slidably equipped with an insulating cutter 3046. The insulating cutter 3046 is connected to the baffle 3044 through a side pull handle via a spring 3045, and a punching device is provided on the side of the side pull handle away from the spring 3045. The punching device preferably uses a telescopic cylinder structure to realize its function.

[0039] Working principle of the present invention: The equipment has two normal working modes: natural ventilation mode (corresponding to Figure 2-Figure 5 The structural form shown) and the strong heat dissipation mode (corresponding to Figure 6 The structural form shown); and the danger relief mode in extreme cases; When the equipment is in natural ventilation mode, the cross guide frame 6 slides axially to the rear end positioning point of the slide rail 7. At this time, the two sets of self-sealing doors 5 and the cooling mechanism 4 symmetrically distributed on the upper and lower sides of the core component loading compartment 3 perform radial expansion movement synchronously under the coordinated action of the cross guide system of the cross guide frame 6, including the long branch guide groove and the short branch guide groove. Its movement trajectory ensures that the end of the self-sealing door 5 near the core component loading compartment 3 is accurately embedded in the socket on the front side of the upper and lower walls of the component. At the same time, the side wall guide rod of the cooling mechanism 4 is inserted into the socket on the front side of the upper and lower walls of the component along the short branch guide groove. The track slides to the intersection with the long branch guide groove, and can pull back the core component loading compartment 3 intersecting with it to move as a whole to the rear cavity of the cabinet 1, causing the cross-hinged swing rod 202 to reach the preset maximum overlapping state, so that the core component loading compartment 3 is accurately positioned in the natural ventilation area. At this time, the grid 303 on the top and bottom walls of the compartment 301 remains in a fully open configuration, forming a coherent airflow channel with the window on the rear side wall of the cabinet 1, achieving passive heat dissipation through air convection effect, significantly reducing the energy consumption requirements of the active heat dissipation system; When the temperature monitoring system built into the cabinet 1 detects in real time that the operating temperature of the equipment has reached a preset threshold, it immediately sends a temperature over-limit determination signal to the temperature monitoring system. The control system then simultaneously outputs a coordinated control instruction to the push-pull device and the circulating cooling system. First, the circulating cooling system is activated. At the same time, the output end of the push-pull device is precisely controlled to carry out the linear displacement of the cross guide frame 6 within a preset stroke. Through mechanical linkage, the relative position of the cooling mechanism 4 and the self-sealing door 5 changes, thereby completing a stepless switch from the natural ventilation mode to the high-efficiency heat dissipation mode. When the equipment switches from the natural ventilation mode to the strong heat dissipation mode, the output end of the push-pull device drives the connecting beam 8 to move in a directional manner toward the front cavity of the cabinet 1, and the cross guide frames 6 on both sides of the connecting beam 8 slide precisely along the axial direction of the slide rail 7 to the middle positioning reference point; at this time, the rigid guide rods of the self-sealing door 5 and the side wall of the cooling mechanism 4 produce centripetal displacement under the constraint of the cross guide system of the cross guide frame 6, driving the self-sealing door 5 and the cooling mechanism 4 to complete the radial contraction movement - the cooling mechanism 4 finally forms an airtight fit with the grid 303 on the top and bottom walls of the cabin 301, and at the same time, the self-sealing door 5 symmetrically penetrates the socket above and below to achieve mechanical locking, so that the cabin 301 constitutes a completely sealed cavity; the circulating cooling system is connected to the sealed cavity through a dual-channel cold circuit composed of a bellows 402 and a sealing cover 401, and the low-temperature working medium is directly introduced into the cabin 301 for forced convection heat exchange with the heating element. While achieving the maximum heat dissipation efficiency of the temperature difference, the multiple sealing structures effectively suppress the leakage of cold air, so that the cooling medium utilization rate is increased to more than 92%; When the equipment completes heat exchange in the strong heat dissipation mode and the operating temperature drops below the preset safety threshold, the temperature monitoring system of the cabinet 1 immediately sends a mode switching trigger signal to the control system, and the control system synchronously sends a reverse control instruction to the push-pull device cross guide frame 6 and the circulating cooling system slide rail 7: first, the cooling medium supply of the slide rail 7 is cut off and the system is shut down, and at the same time, the output end of the cross guide frame 6 is driven to perform a quantitative retraction displacement; this action causes the connecting beam 8 to drive the double-sided cross guide frame 6 to slide in the opposite axial direction along the slide rail 7 through mechanical linkage, and then the guide rod of the self-sealing door 5 and the cooling mechanism 4 produces centrifugal displacement under the action of the cross guide system, and finally the cooling mechanism 4 and the grid 303 are released from the sealed engagement state, and the self-sealing door 5 synchronously exits the socket locking position, so that the cabin 301 restores the two-way open structure of the top and bottom grids 303, and the entire equipment is completely restored to the initial position of the natural ventilation mode through this reverse motion chain; When the equipment triggers the danger relief mode, that is, the smoke monitoring system of the cabinet 1 detects in real time that the smoke concentration in the cabin 301 exceeds the standard, and immediately sends a fire emergency command to the control system; the control system preferentially activates the punching device to carry the insulating cutter 3046 to quickly cut off the outlet hole 3042, and instantly cuts off all the conductive lines therein through mechanical punching to achieve electrical isolation; at the same time, the push-pull device performs full-stroke advancement, driving the connecting beam 8 to drive the double-sided cross guide frame 6 to move along the axial limit of the slide rail 7, so that the self-sealing door 5 and the cooling mechanism 4 complete the emergency locking under the action of the cross guide system - after the cabin 301 forms a fireproof seal, the cooling mechanism 4. The self-sealing hatch 5 and the core component loading compartment 3 can continue to move forward as a whole, causing the cross-hinged rocker arm 202 to gradually expand, and accurately transporting the closed structure constructed by the cooling mechanism 4, the self-sealing hatch 5 and the core component loading compartment 3 to the floor drain 10 fire extinguishing station; after the displacement sensing system confirms the positioning, the solenoid valve of the water supply part 9 immediately opens the high-pressure water system, and when the water flows through the variable joint 403, it dissolves the soluble film layer 4032 and activates the drain groove 4031 channel, and implements three-dimensional spray fire extinguishing inside the cabin 301 through the diversion nozzle of the sealing cover 401. The system can complete the entire emergency response process from fire detection to fire extinguishing agent delivery within 12 seconds.

[0040] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or modifications within the technical scope disclosed by the present invention; according to the technical plan and its improved conception of the present invention, these should be included under the protection of the present invention.
