Description

Technical Field

[0001] The present invention relates to the technical field of power distribution cabinets, and in particular to an intelligent modular and expandable high- and low-voltage integrated power distribution cabinet system and a method thereof. Background Art

[0002] High and low voltage distribution cabinets are distribution equipment used for power distribution, control, metering and cable connection in power supply systems. Generally, power supply bureaus and substations use high voltage switch cabinets, which are then stepped down by transformers and led out to low voltage distribution cabinets. Low voltage distribution cabinets are then led to distribution boards, control boxes and switch boxes for each power user. The equipment inside is a distribution device that is assembled into one by some switches, circuit breakers, fuses, buttons, indicator lights, meters, wires and other protective devices to meet the design functional requirements.

[0003] The existing high and low voltage distribution cabinets have different sizes according to different application environments. In real life, the most common one is the outdoor small high voltage distribution cabinet. This kind of distribution cabinet is small in size and the internal electrical equipment is relatively loose, which makes it convenient for the staff to inspect and maintain it. However, in some factory areas, due to the need to control the power of various large equipment, the high and low voltage distribution cabinets used are also relatively large in size. This large high and low voltage distribution cabinet also has obvious defects in actual use, such as:

[0004] The size of the cabinet is large and the electrical equipment inside is compactly installed. This type of distribution cabinet is very cumbersome and difficult to maintain and clean during use. Workers need to disassemble multiple panels and then expose the internal equipment for maintenance. In addition, the compact installation of electrical equipment will also cause heat accumulation, and the fan will drive the fluff in the external air into the equipment, which will affect the equipment.

[0005] Therefore, an intelligent modular and expandable high and low voltage integrated distribution cabinet system that can be easily maintained and used is designed to solve such defects. Summary of the invention

[0011] Preferably, a retractable bottom groove is provided at the top of the lower limiting guide plate, and the front and rear sides of the bottom of the inner cavity of the retractable bottom groove are fixedly connected with a third spring, the top of the third spring is fixedly connected with an insulating bottom plate used in conjunction with the retractable bottom groove, the bottom of the insulating bottom plate is fixedly connected with a second tooth bar used in conjunction with the first tooth bar, and the bottom of the limiting guide plate is provided with an engaging notch used in conjunction with the second tooth bar and the first tooth bar.

[0012] Preferably, the top and bottom of the inner cavity of the side concave frame are fixedly connected with a slide plate frame, and a filter screen plate is slidably installed between the two slide plate frames on the same side, and the surface of the side concave frame is provided with a pull-out opening for use with the filter screen plate, and a linkage groove connected to the retraction bottom groove is provided at the lower part of the inside of the side concave frame, and a fourth spring is fixedly connected to the bottom of the inner cavity of the linkage groove, and the top of the fourth spring is fixedly connected to a bent plate, a positioning slot is provided at the bottom of the filter screen plate, and the positioning slot sequentially passes through the lower slide plate frame and the side concave frame and extends to the inner side of the linkage slot, and the top of the bent plate is fixedly connected with a pin rod for use with the positioning slot.

[0014] Preferably, the two side concave frames, on opposite sides, are fixedly connected to a cooling fan by openings, and a plurality of cooling fans are provided, and the rear portions of the opposite sides of the two side concave frames are fixedly connected to an inclined pressure plate used in conjunction with a transverse pressure slide, and the number of the inclined pressure plates is the same as that of the transverse pressure slide.

[0015] The present invention also discloses a method for using an intelligent modular and expandable high and low voltage integrated distribution cabinet system, which specifically comprises the following steps:

[0016] S1. When using, if you only need to press the electrical equipment, you can directly flip open the cabinet door panel, which can directly expose the front of the electrical equipment. In daily use, start the cooling fans on both sides to blow air into the hollow distribution frame to reduce the temperature inside the hollow distribution frame, and the filter plate can filter the air blown in by the cooling fan to prevent fluff in the air from entering the hollow distribution frame and being adsorbed on the surface of the equipment;

[0017] S2. If it is necessary to maintain and clean the interior of the hollow distribution frame, first pull the side concave frames on both sides to both sides under the action of the limit guide plate, and stop after the side concave frames are pulled to the limit positions on both sides. During the pulling process of the side concave frames, the inclined pressure plate will be separated from the top of the horizontal pressure slide plate. At this time, the horizontal pressure slide plate will drive the pressure moment plate to rise under the elastic force of the second spring and will no longer block and limit the sealing baffle. After the pressure moment plate rises, the sealing baffle will be pulled and flipped under the elastic pulling force of the first spring to open and expose the operating slot. The wiring harness connected to the rear of the electrical equipment is pulled out from the inside of the threading circular mouth, and the opened operating slot is used to install the rear of the electrical equipment. After the side concave frames are fully opened, the staff will flip the cabinet door panel 90 degrees to open it, and then enter the side through the opened U-shaped panel. The inner side of the concave frame is used to maintain and clean the side of the hollow distribution frame. When the staff steps on the top of the insulating bottom plate, the insulating bottom plate descends to make the second tooth bar mesh with the first tooth bar. At this time, the entire side expansion mechanism is fixed, ensuring that the side concave frame as a whole will not be pushed and displaced by external factors when the staff works on the inner side of the side concave frame, thereby protecting the safety of the internal staff. When the insulating bottom plate is pressed, the bending plate will also be pressed to drive the latch rod to descend and be pulled out from the inner side of the positioning slot. At this time, the filter screen plate loses its limit, and then the filter screen plate is pushed through the pull-out opening to move forward to the front of the side concave frame. After the filter screen plate is moved forward, it is located on the inner side of the U-shaped clamp frame, and then the U-shaped clamp frame is pulled up and down under the guidance of the handle vertical rod. When the U-shaped clamp frame moves, the fluff on the surface of the filter screen plate will be scraped off;

[0018] S3. When the maintenance of the inside of the hollow distribution frame is completed, enter the inner side of the side concave frame again, press the insulating bottom plate to fix the side expansion mechanism as a whole, and at the same time lower the latch rod again, then pull the filter screen plate back to the inner side of the side concave frame to filter the cooling fan, and after leaving the side concave frame, the latch rod rises under the elastic force of the fourth spring and inserts into the positioning slot to fix the filter screen plate, and then push the two side concave frames to close and move together. During the movement of the side concave frames, the inclined pressure plate will squeeze the horizontal pressure slide plate. When the horizontal pressure slide plate is squeezed and lowered, it will use the pressure moment plate to push the sealing baffle to pull the sealing baffle to flip the sealing baffle and close the operating slot. After the side concave frame is completely closed with the hollow distribution frame, the maintenance work is completed.

[0019] Preferably, in step S2, a bristle brush is provided on the inner side of the U-shaped clamp frame.

[0020] The present invention provides an intelligent modular expandable high and low voltage integrated power distribution cabinet system and method thereof. Compared with the existing technology, it has the following beneficial effects:

[0021] (1) The intelligent modular expandable high and low voltage integrated distribution cabinet system and method thereof, by combining the distribution cabinet mechanism and the side expansion mechanism, the two mechanisms can be separated from the distribution cabinet mechanism by pulling the two side expansion mechanisms during maintenance, thereby exposing the two sides of the hollow distribution frame to increase the operating space, and in the process of pulling, the linkage between the structures is used to open several sealing baffles, which is convenient for the staff to install and observe the wiring harness from the rear, and at the same time, the filter screen can be pulled and locked for cleaning, which satisfies the current use.

[0022] (2) The intelligent modular expandable high and low voltage integrated distribution cabinet system and method thereof are characterized by installing side recessed frames on both sides of the hollow distribution frame by means of limit guide plates, and installing a cooling fan on one side of the side recessed frame, and using the filter screen plate and the insulating bottom plate. The arrangement of these structures enables the cooling fan to blow air to cool the inside of the hollow distribution frame on a daily basis, and the filter screen plate can filter the fluff in the air to prevent it from entering the interior of the equipment. At the same time, when the staff enters the side recessed frame for operation, they can use the pressing of the insulating bottom plate to engage the second tooth bar with the first tooth bar, thereby fixing the side expansion mechanism as a whole, thereby ensuring the safety of the staff during internal maintenance.

[0023] (3) The intelligent modular expandable high and low voltage integrated distribution cabinet system and method thereof, by installing a U-shaped clamp frame on the surface of the cabinet door panel using a handle vertical rod, and using it in conjunction with a bent plate and a latch rod, the arrangement of these structures can unlock the filter screen after the insulating bottom plate is pressed, making it convenient to pull out the filter screen, and the pulled out filter screen can be docked with the U-shaped clamp frame, so that the U-shaped clamp frame can scrape off the fluff on the surface of the filter screen, thereby ensuring stability during subsequent use.

[0024] (4) The intelligent modular expandable high and low voltage integrated power distribution cabinet system and method thereof are characterized by opening an operation slot at the rear of the hollow power distribution frame, and installing a horizontal pressure slide plate and a pressure moment plate used in conjunction with a sealing baffle on the inner side of the concave slot using a positioning vertical rod, and using the inclined pressure plate. The arrangement of these structures can use the pull-out opening to squeeze the horizontal pressure slide plate during the process of pulling and closing the side concave frame, so that the sealing baffle can be opened and closed, which can not only facilitate the management of the wire harness by the staff, but also protect the wire harness.

[0041] The present invention also discloses a method for using an intelligent modular and expandable high and low voltage integrated distribution cabinet system, which specifically comprises the following steps:

[0042] S1. When in use, if only a pressing operation is required on the electrical device 104, the cabinet door panel 204 can be directly flipped open to expose the front of the electrical device 104. In daily use, the cooling fans 220 on both sides are started to blow air into the hollow power distribution frame 101 to reduce the temperature inside the hollow power distribution frame 101, and the filter plate 212 can filter the air blown in by the cooling fan 220 to prevent fluff in the air from entering the hollow power distribution frame 101 and being adsorbed on the device surface;

[0043] S2. If it is necessary to maintain and clean the interior of the hollow distribution frame 101, first pull the side concave frames 202 on both sides to the sides under the action of the limit guide plate 201, and stop after the side concave frames 202 are pulled to the limit positions on both sides. During the pulling process of the side concave frames 202, the inclined pressure plate 221 will be separated from the top of the horizontal pressure slide plate 106. At this time, the horizontal pressure slide plate 106 drives the pressing moment plate 109 to rise under the elastic force of the second spring 113 and no longer blocks the sealing baffle 110. After the pressing moment plate 109 is raised, the sealing baffle 110 is pulled and flipped under the elastic tension of the first spring 111 to open and expose the operating slot 107, and the wiring harness connected to the rear of the electrical equipment 104 is pulled out from the inside of the threading round hole 108, and the opened operating slot 107 is used to install the rear of the electrical equipment 104. After the side concave frame 202 is fully opened, the staff flips the cabinet door panel 204 90 degrees to open it, and then enters the side through the opened U-shaped panel 203. The inner side of the concave frame 202 is used to maintain and clean the side of the hollow distribution frame 101. When the staff steps on the top of the insulating bottom plate 207, the insulating bottom plate 207 descends to make the second tooth bar 208 mesh with the first tooth bar 103. At this time, the entire side expansion mechanism 2 is fixed, ensuring that the side concave frame 202 as a whole will not be pushed and displaced by external factors when the staff works inside the side concave frame 202, thereby protecting the safety of the internal staff. At the same time, the bent plate 215 is pressed to drive the latch rod 217 to descend and be drawn out from the inner side of the positioning slot 214. At this time, the filter screen plate 212 loses its limit position, and then the filter screen plate 212 is pushed through the draw-out opening 211 to move forward to the front of the side concave frame 202. After the filter screen plate 212 is moved forward, it is located on the inner side of the U-shaped clamping frame 219.

When the U-shaped clamping frame 219 moves, the fluff on the surface of the filter screen plate 212 is scraped off.

[0044] S3, when the maintenance of the hollow distribution frame 101 is completed, the side concave frame 202 is entered again to press the insulating bottom plate 207 to fix the side expansion mechanism 2 as a whole, and the latch rod 217 is lowered again, and then the filter screen 212 is pulled back to the inside of the side concave frame 202 to filter the cooling fan 220. After leaving the side concave frame 202, the latch rod 217 rises under the elastic force of the fourth spring 216 and inserts into the positioning slot 214 to filter the cooling fan 220. The mesh plate 212 is fixed, and then the two side concave frames 202 are pushed to move together. During the movement of the side concave frames 202, the inclined pressure plate 221 will squeeze the transverse pressure slide 106. When the transverse pressure slide 106 is squeezed and lowered, the pressure moment plate 109 will be used to push the sealing baffle 110 so that the sealing baffle 110 pulls the sealing baffle 110 to flip and close the operating slot 107. After the side concave frames 202 are completely closed with the hollow distribution frame 101, the maintenance work is completed.

2. A method for using the intelligent modular and expandable high and low voltage integrated distribution cabinet system according to claim 1, characterized in that: The specific steps include: S1. When in use, if only a pressing operation is required on the electrical device (104), the cabinet door panel (204) can be directly flipped open, so that the front of the electrical device (104) can be directly exposed. During daily use, the cooling fans (220) on both sides are started to blow air into the hollow power distribution frame (101), thereby reducing the temperature inside the hollow power distribution frame (101), and the filter screen (212) can filter the air blown in by the cooling fan (220), thereby preventing fluff in the air from entering the hollow power distribution frame (101) and being adsorbed on the surface of the device; S2. If it is necessary to maintain and clean the interior of the hollow distribution frame (101), first, under the action of the limit guide plate (201), the side concave frames (202) on both sides are pulled to the limit positions on both sides and then stopped. During the pulling process of the side concave frames (202), the inclined pressure plate (221) will be separated from the top of the horizontal pressure slide plate (106). At this time, the horizontal pressure slide plate (106) drives the pressure moment plate (109) to rise under the elastic force of the second spring (113) and no longer blocks the sealing baffle (110) to limit the position. After the pressing moment plate (109) has risen completely, the sealing baffle (110) is pulled and flipped under the elastic pulling force of the first spring (111) to open and expose the operating slot (107). The wiring harness connected to the rear of the electrical device (104) is pulled out from the inside of the threading round opening (108). The opened operating slot (107) is used to install the rear of the electrical device (104). After the side recessed frame (202) is fully opened, the staff flips the cabinet door panel (204) 90 degrees to open it, and then enters the side recessed frame through the opened U-shaped panel (203). The inner side of the frame (202) is used to maintain and clean the side of the hollow distribution frame (101). When the worker steps on the top of the insulating bottom plate (207), the insulating bottom plate (207) descends to cause the second tooth bar (208) to mesh with the first tooth bar (103). At this time, the entire side expansion mechanism (2) is fixed, ensuring that the side concave frame (202) as a whole will not be pushed and displaced by external factors when the worker is working inside the side concave frame (202), thereby protecting the safety of the internal workers. At the same time, when the insulating bottom plate (207) is pressed, The bent plate (215) is pressed to drive the latch rod (217) to descend and be pulled out from the inner side of the positioning slot (214). At this time, the filter screen plate (212) loses its limit position, and then the filter screen plate (212) is pushed through the pull-out opening (211) and moves forward to the front of the side concave frame (202). After the filter screen plate (212) has moved forward, it is located on the inner side of the U-shaped clamp frame (219). Then, the U-shaped clamp frame (219) is pulled up and down under the guidance of the handle vertical rod (218). When the U-shaped clamp frame (219) moves, the fluff on the surface of the filter screen plate (212) is scraped off; S3, when the maintenance of the inside of the hollow distribution frame (101) is completed, the side concave frame (202) is entered again to press the insulating bottom plate (207) to fix the side extension mechanism (2) as a whole, and the latch rod (217) is lowered again, and then the filter screen plate (212) is pulled back to the inside of the side concave frame (202) to filter the cooling fan (220). After leaving the side concave frame (202), the latch rod (217) rises under the elastic force of the fourth spring (216) and is inserted into the positioning slot (214) to fix the filter screen. The plate (212) is fixed, and then the two side concave frames (202) are pushed to move together. During the movement of the side concave frames (202), the inclined pressure plate (221) will squeeze the horizontal pressure slide plate (106). When the horizontal pressure slide plate (106) is squeezed and lowered, the sealing baffle (110) is pushed by the pressure moment plate (109) so that the sealing baffle (110) pulls the sealing baffle (110) to flip and close the operating notch (107). After the side concave frames (202) are completely closed with the hollow distribution frame (101), the maintenance work is completed.

3. The method for using the intelligent modular expandable high and low voltage integrated distribution cabinet system according to claim 2, characterized in that: In step S2, a bristle brush is provided on the inner side of the U-shaped clamp frame (219).
