Description

Technical Field

[0001] The invention relates to the technical field of power distribution equipment, and specifically discloses a modular outdoor intelligent power distribution cabinet. Background Art

[0002] An outdoor power distribution cabinet is a power distribution device used in outdoor environments. Its main function is to distribute, control and protect the electric energy of power systems or equipment in outdoor environments. The existing outdoor power distribution cabinet has a simple structure. It is mainly composed of a cabinet body surrounded by stainless steel plates. The cabinet body is provided with horizontal rows or brackets for installing electrical components. At the same time, in order to ensure its internal heat dissipation effect, corresponding heat dissipation holes are opened on the side of the cabinet body, and even a heat dissipation fan is provided for active heat dissipation.

[0003] For example, the invention patent with application number 2023112889326 discloses an outdoor distribution box, including a box and a surveillance camera. The surveillance camera is arranged on the box for real-time monitoring of the surrounding environment of the box; a mobile component is arranged on the box, and the mobile component acts on the surveillance camera to store the surveillance camera inside the box. At the same time, corresponding electrical components are installed in the box in a horizontal row, and heat dissipation holes are opened on the side of the box. The outdoor distribution box disclosed in the patent is a common distribution cabinet structure on the market. Although it meets the distribution, control and protection needs of power systems or equipment to a certain extent, there are still some unresolved problems. First, the electrical components inside the existing outdoor power distribution cabinets generally integrate the corresponding electrical components of multiple power systems or equipment, and the electricians usually install them irregularly in horizontal rows during installation, and it is impossible to concentrate the electrical components corresponding to the same power system or equipment, resulting in the need to inspect and maintain a certain power system or equipment, which may cause electric shock accidents due to contact with other electrical components. Therefore, the entire distribution cabinet needs to be disconnected, and it is impossible to maintain the normal operation of other power systems or equipment that do not need to be inspected; in addition, the electrical components corresponding to different power systems or equipment generate different amounts of heat during operation, and some electrical components with larger amounts of heat will transfer heat to the entire cabinet, causing other electrical components to be affected by high temperature and prone to failure. In addition, the entire cabinet has a large internal volume, and even if the heat is actively cooled by the heat dissipation motor, the internal temperature cannot be quickly reduced. Second, in some outdoor environments with poor environments, the presence of heat dissipation holes will cause dust in the air to enter and adhere to the surface of the electrical components, and long-term operation will cause failures, and it is impossible to ensure that the internal electrical components can operate stably for a long time.

[0009] As a further configuration of the above scheme, baffles inclined downward are provided on both side walls of the liquid cooling box below the water distribution pipe, and the baffles on both sides are staggered up and down.

[0010] As a further arrangement of the above scheme, a row of wire end connection slots are provided at the front end of the electrical device aggregation plug, and a plug-in copper column corresponding to each wire end connection slot is provided at the rear end of the electrical device aggregation plug.

[0014] As a further configuration of the above scheme, a front cabinet opening and a rear cabinet opening are respectively opened at the front and rear ends of the cabinet body, and a front cabinet door and a rear cabinet door are rotatably installed in the front cabinet opening and the rear cabinet opening respectively.

[0015] When the modular outdoor intelligent power distribution cabinet disclosed in the present invention is used, the electrical components in multiple power systems or equipment are respectively installed in the corresponding modular assembly drawer boxes, and the electrical components are connected to the electrical component convergence plug through wires, and at the same time, the access end in the power system or equipment is also connected to the electrical component access convergence socket through wires. After the circuit connection is completed, the modular assembly drawer box is pushed into the cabinet along the track plate, and the electrical component convergence plug is connected to the electrical component access convergence socket by plugging the copper column, so that the electrical components in the same power system or equipment are connected to the circuit. In the subsequent long-term operation process, when a certain power system or equipment needs to be inspected and maintained, the operator directly opens the front cabinet door and draws the corresponding modular assembly drawer box out of it. During the process of drawing out, the electrical component convergence plug in the modular assembly drawer box is separated from the electrical component access convergence socket, so that all the electrical components in the modular assembly drawer box can be disconnected from the circuit, and the operator can directly perform inspection and maintenance without the risk of electric shock. At the same time, the electrical components in other modular assembly drawers operate normally and are not affected by this inspection and maintenance.

[0016] In addition, during the long-term operation of the entire modular outdoor intelligent power distribution cabinet, the electrical components in each modular assembly drawer box will generate different heat due to differences in type and current and voltage. When the temperature sensor detects that the temperature in a modular assembly drawer box is too high, liquid cooling will be performed. The specific operation is to first open the solenoid valve corresponding to the modular assembly drawer box through the controller, and then start the circulating liquid pump to inject the coolant at the bottom of the liquid cooling box into the heat exchange tube of the cooling interlayer, and then through the effect of heat conduction, the circulating coolant can achieve rapid cooling of the electrical components in the corresponding modular assembly drawer box. In addition, due to the sealing design of the entire cabinet, dust and impurities in the external environment will not enter the interior, causing dust on the surface of the electrical components and malfunctions.

[0017] At the same time, the coolant that has undergone heat exchange will fall from the top of the liquid cooling box, flow back and forth along the baffle and drip downward. At this time, the external cold air can take away most of the heat through the convection of the first heat dissipation hole to cool the coolant. After cooling, it will be detected by the temperature measuring component. Once it is found that the temperature of the refluxed coolant is too high, the active cooling fan will be started to actively and strongly dissipate the heat of the coolant in the reflux process, ensuring that the coolant has a lower temperature and can effectively dissipate the heat of the electrical components in the modular assembly drawer box, thereby maintaining the electrical components in a high temperature environment. Long-term stable operation.

[0018] Compared with the prior art, the present invention has the following beneficial effects: The present invention adopts a modular assembly drawer box to install the electrical components in each independent power system or equipment, and realizes the circuit connection of the electrical components through the plugging action between the electrical component aggregation plug and the electrical component access aggregation socket, and then cooperates with the pulling and pulling action of the modular assembly drawer box to realize the circuit connection and disconnection of the electrical components. When a certain power system or equipment needs to be inspected and maintained, the modular assembly drawer box can be directly pulled out to automatically cut off the power to the electrical components inside. After the power is cut off, safe inspection and maintenance can be carried out directly, which not only greatly improves the subsequent inspection and maintenance efficiency of the electrical components, eliminates safety risks and hidden dangers, but also can ensure the normal operation of other power systems and equipment.

[0019] The present invention also sets a cooling interlayer composed of heat dissipation fins and heat exchange tubes at the bottom of each modular assembly drawer box, and then installs the electrical components on the bottom wall of the drawer box through a mounting frame plate with high thermal conductivity. When the temperature in a modular assembly drawer box is too high, the electrical components in the drawer box can be directly and independently cooled quickly through a liquid cooling unit to ensure the stable operation of the electrical components in the drawer box. In addition, since the electrical components in different power systems or equipment are concentrated in different drawer boxes, the heat generated by some electrical components with larger heat generation during operation is difficult to be transferred to other drawer boxes, thereby avoiding the problem caused by the synchronous high-temperature operation of all electrical components in the cabinet due to the large heat generation of a certain electrical component. In addition, the internal volume of the drawer box is small, and starting the liquid cooling unit can quickly achieve its own cooling, effectively ensuring the stable operation of the internal electrical components.

[0020] The present invention uses a liquid cooling unit to independently control the temperature of each modular assembly drawer box. During operation, the heat generated by the electrical components is taken away by the circulation of the coolant, so that the entire cabinet is effectively isolated from the outside world, avoiding the problem of dust and impurities easily entering and adhering to the electrical components when used outdoors, thereby effectively ensuring the stable operation of the entire power distribution cabinet. In addition, the cooling water after heat exchange uses a specially designed liquid cooling box, so that it can effectively contact the external cold air when flowing from top to bottom along the baffle surface, thereby ensuring the effective dissipation of the heat of the cooling water, and the strong heat dissipation of the active heat dissipation fan can ensure that the entire liquid cooling unit has sufficient heat dissipation and cooling effect on the modular assembly drawer box.

[0021] The present invention also improves the design between the modular assembly drawer box and the track plate, adopts a positioning card slot and a method of connecting the positioning card blocks through a spring, so that when the drawer box is pushed into the cabinet so that the electrical component convergence plug is connected to the electrical component access convergence socket, the connection stability between the two can be maintained, and in the process of pulling out the drawer box, the card action between the two can be used again to avoid the drawer box from being completely pulled out of the cabinet and sliding, making the entire distribution cabinet installation, inspection and maintenance process more convenient and safe.

[0027] A front cabinet opening and a rear cabinet opening are respectively provided on the front and rear sides of the cabinet body, and a front cabinet door 101 and a rear cabinet door 102 are respectively rotatably installed in the front cabinet opening and the rear cabinet opening through hinges, and then a vertical partition board 103 is provided in the inner cavity of the cabinet body 1, so that the inner cavity of the cabinet body 1 is divided into two parts, front and back. In addition, a plurality of track boards 5 arranged at equal intervals up and down are provided on the left and right side walls of the cabinet body 1 in front of the partition board 103, and then each modular assembly drawer box 2 is slidably drawn and arranged between two track boards 5 aligned left and right.

[0028] Reference Figure 5 and attached Figure 6 The modular assembly drawer box 2 includes a drawer box 201 with four surrounding edges. Slides 202 matching the track plate 5 are arranged on the left and right sides of the drawer box 201, and buckle holes 203 are opened on the front side of the drawer box 201, so that the entire drawer box 201 can be pushed into the cabinet 1 along the track plate 5 or pulled out from the cabinet 1. A mounting frame 204 for mounting various electrical components is arranged on the bottom wall of the drawer box 201, and then an electrical component convergence plug 205 is arranged at one end of the rear side of the drawer box 201. A row of wire end connection grooves 2051 are arranged on the electrical component convergence plug 205, and plug-in copper columns 2052 corresponding to each wire end connection groove are arranged on the outer end surface of the electrical component convergence plug 205 facing the partition plate 103, so that the electrical components installed on the mounting frame 204 can be connected to the wire end connection groove 2051 through wires, and then connected and set through the corresponding plug-in copper columns 2052. In addition, in order to facilitate the installation or adjustment of the electrical components inside the drawer box 201, the front side of the drawer box 201 is rotatably connected by a hinge, and then the two side ends and the front side of the drawer box 201 are magnetically fixed by magnetic strips 206.

[0029] Reference Figure 3 and attached Figure 4A plurality of electrical device access convergence sockets 6 are arranged at equal intervals in the upper and lower directions on the partition plate 103, and a jack corresponding to each group of plug-in copper pillars 2052 is provided at the front end of each electrical device access convergence socket 6, and a wire end connection groove corresponding to each jack is also provided at the rear end of the electrical device access convergence socket 6. In addition, a wire inlet and outlet terminal 7 corresponding to each electrical device access convergence socket 6 is provided on the side of the cabinet 1, and a dustproof side box 8 containing all the wire inlet and outlet terminals 7 is provided on the side of the cabinet 1, and a movable box door 801 is provided on the front side of the dustproof side box 8, and a wire main inlet and outlet 802 is provided at the bottom thereof.

[0030] When the modular outdoor intelligent power distribution cabinet disclosed in this embodiment 1 integrates the electrical components in multiple power systems or devices, the electrical components in the power systems or devices are installed on the mounting frame plate 204 in the same modular assembly drawer box 2, and then each electrical component is connected to the corresponding wire end connection slot of the electrical device convergence plug 205 through the wire. At the same time, the line corresponding to each power system or device is extended from the wire inlet and outlet end 7 to the rear end of the inner cavity of the cabinet 1, and then the wire is connected to the corresponding wire end connection slot on the electrical device access convergence socket 6. After the connection is completed, the modular assembly drawer box 2 is directly pushed into the cabinet 1 along the track plate 5 until the plug copper column 2052 on the electrical device convergence plug 205 is fully inserted into the jack of the electrical device access convergence socket 6. At this time, the entire electrical component access circuit of the corresponding circuit system or device is controlled and monitored accordingly. When a circuit system or device needs to be inspected and maintained later, the modular assembly drawer box 2 corresponding to the circuit system or device is directly pulled out. After the withdrawal, the corresponding circuit can be completely disconnected, and then the inspection and maintenance can be carried out directly, which fully guarantees the construction safety of the operators. At the same time, other power systems or equipment can still operate normally without being affected. Example 2

[0031] Example 2 discloses a modular outdoor intelligent power distribution cabinet that is optimized and improved based on the technical solution in Example 1. The similarities between it and Example 1 will not be described again.

In this embodiment 2, through the above design, after the modular assembly drawer box 2 is pushed into the cabinet 1 so that the electrical device convergence plug 205 is fully plugged into the electrical device access convergence socket 6, the rear positioning block 503 is just matched with the positioning slot 2021, thereby effectively fixing the entire modular assembly drawer box 2, preventing the modular assembly drawer box 2 from sliding and causing the electrical device convergence plug 205 to separate or disconnect from the electrical device access convergence socket 6, thereby ensuring the stability of the circuit connection of the electrical components.

[0033] When the modular assembly drawer box 2 needs to be pulled out from the cabinet 1 for inspection, the operator only needs to pull it outward as a whole with force, so that under the squeezing action of the positioning slot 2021 on the positioning block 503, it overcomes the force of the spring 502 and retracts, until the two slip off, the modular assembly drawer box 2 can be smoothly pulled out, until the positioning slot 2021 interacts with the front positioning block 503 to limit it again, thereby avoiding excessive pulling of the modular assembly drawer box 2 from the cabinet 1, causing it to slip off the track plate 5. Example 3

[0034] Example 3 discloses a modular outdoor intelligent power distribution cabinet that is further optimized based on Example 2, which mainly aims at how to achieve effective heat dissipation and cooling of electrical components under long-term high-temperature operation while preventing external dust from entering the cabinet and polluting the electrical components.
