Description

Technical Field

[0001] This invention relates to the field of power distribution cabinet technology, specifically a modular heat dissipation power distribution cabinet. Background Technology

[0002] Distribution cabinets are the final-level power distribution equipment in a power system. They receive, distribute, control, and protect electrical energy in the power system. They can be divided into two main categories: high-voltage switchgear and low-voltage distribution cabinets. They are one of the core infrastructures that ensure the stable and safe operation of various electrical equipment. Their core function is to rationally distribute the electrical energy transmitted from the upper-level power grid to various power lines or electrical equipment according to actual power demand, while monitoring and protecting against faults such as overload, short circuit, and leakage in the circuit.

[0003] Excessive temperature can seriously affect the operational stability and service life of power distribution cabinets. The existing power distribution cabinets are mostly integrated fixed structures, which cannot be modularized. The functional modules (such as power distribution modules, heat dissipation modules, and monitoring modules) cannot be quickly disassembled and replaced, which increases maintenance costs and workload. It is also impossible to install and adapt power components and equipment of different sizes and specifications. Summary of the Invention

[0004] The purpose of this invention is to provide a modular heat dissipation power distribution cabinet to solve the problem of inconvenience in using existing power distribution cabinets.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A modular heat dissipation power distribution cabinet includes a cabinet body and further includes:

[0007] The cabinet has a fixed plate, and the interior of the cabinet is equipped with a partition that divides the internal cavity of the cabinet into an equipment area and a heat exchange area. The equipment area has multiple mounting strips fixed to the inner wall of the cabinet. Each mounting strip has a mounting buckle. A crossbeam is positioned between two mounting buckles. The crossbeam has a sliding groove inside, and a slider is positioned inside the sliding groove. A telescopic tube is mounted on the slider. A connecting rod is positioned between two telescopic tubes, and a support block is mounted on the connecting rod. A fixed plate is positioned between two support blocks. The fixed plate has a heat dissipation groove and a guide groove, and a sliding block is positioned inside the guide groove.

[0008] The clamping plate has a support frame on the support block, a pressure plate at one end of the support frame, a fixing plate on the side wall of the fixing plate, a plurality of clamping plates on the fixing plate, a telescopic plate slidably disposed on the side wall of the fixing plate, a first rotating plate at one end of the telescopic plate passing through the fixing plate, a fixing rod at one end of the clamping plate, a second rotating plate between the two fixing rods, a movable rod on the second rotating plate, and a square groove on the first rotating plate that mates with the movable rod.

[0009] The transmission mechanism, connected to the telescopic plate, can drive the sliding block to slide along the guide groove. The sliding block, in cooperation with the transmission mechanism, drives the clamping plate to move. Multiple clamping plates press and fix the inserted equipment by bringing them closer together.

[0010] Based on the above technical solutions, the present invention also provides the following optional technical solutions:

[0011] In one alternative embodiment: the transmission mechanism includes a transmission plate, a sliding plate, and a gear; the sliding plate is provided inside the guide groove; the transmission plate is provided between the sliding block and the support block; through grooves are provided on both sides of the support plate; a rotating shaft is provided inside the through groove; a gear is provided outside the rotating shaft; and gear grooves that mesh with the gear are provided on both the sliding plate and the telescopic plate.

[0012] In one alternative: the slider is provided with a connecting plate, a lifting plate is provided between two connecting plates, the lifting plate is provided with multiple slots, a connecting pipe is provided at the center of the fixed plate, and a pressure block is provided at the top of the connecting pipe.

[0013] In one alternative: a pressure rod is provided at the bottom end of the connecting pipe, and a locking block is provided at the bottom end of the pressure rod, the locking block being inserted into the slot.

[0014] In one alternative: an installation plate is provided inside the heat exchange zone, a fan and a heat exchanger are provided on the installation plate, cold air pipes are provided on both sides inside the cabinet, an air outlet pipe is provided on the lifting plate, and a joint is provided between the air outlet pipe and the cold air pipe.

[0015] In one alternative: the cabinet body is provided with a cabinet door on the outside, the cabinet door is provided with a handle, and the cabinet body is provided with a dustproof net.

[0016] In one alternative: the mounting clip is provided with a screw, one end of which passes through the mounting strip.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] Modular heat dissipation distribution cabinets can adapt to power distribution equipment of different heights. Through the clamping structure of pressure plates and clamping plates, they can achieve adaptive fixation of the front, back, and sides of the equipment without modifying the overall structure of the distribution cabinet. They can adapt to equipment of different thicknesses and widths, meet the installation requirements of different specifications of equipment, improve the versatility and reusability of the distribution cabinet, and simplify the equipment installation process without the need for manual step-by-step operation of each fixing component. This reduces the difficulty of operation for workers and improves the efficiency of equipment installation and maintenance. Cool air is blown onto the surface of the equipment through the air outlet pipe and flows into the heat dissipation tank through the connecting pipe to achieve heat dissipation at the bottom of the equipment, solving the problem of heat accumulation during equipment operation.

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0031] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0032] like Figure 1-10 As shown, a modular heat dissipation power distribution cabinet according to an embodiment of the present invention includes a cabinet body 1, and further includes:

[0033] The cabinet 1 includes a fixed plate 18. A partition 10 divides the cabinet 1 into an equipment area 101 and a heat exchange area 102. The equipment area 101 houses various electronic components, power distribution modules, and the fixed plate 18, while the heat exchange area 102 accommodates heat dissipation components to facilitate heat exchange between the equipment area 101 and the external environment, preventing heat buildup. Multiple vertical mounting strips 5 are installed inside the equipment area 101 and are fixed to the inner wall of the cabinet 1. Mounting clips 13 are mounted on the mounting strips 5. A crossbeam 12 is positioned between two mounting clips 13. A sliding groove 121 is formed inside the crossbeam 12, and a slider 16 slides within the sliding groove 121. A telescopic tube 15 is mounted on the slider 16, and a connecting rod 14 is positioned between two telescopic tubes 15. The connecting rod 14 has two ends respectively... The connecting rod 14 is slidably engaged with two telescopic tubes 15. When it is necessary to disassemble the connecting rod 14, the two telescopic tubes 15 can be pulled closer to each other to disengage the telescopic tubes 15 from the slider 16, thereby realizing the quick disassembly of the connecting rod 14 and facilitating the maintenance and replacement of subsequent components. The connecting rod 14 is provided with a support block 17, and a fixing plate 18 is horizontally arranged between the two support blocks 17. The fixing plate 18 is provided with a heat dissipation groove 181 and a guide groove 182. The fixing plate 18 is used to support and fix the electronic components and power distribution equipment installed in the power distribution cabinet, providing a stable installation reference for the power distribution equipment. The heat dissipation groove 181 runs through the upper and lower surfaces of the fixing plate 18, accelerating the dissipation of heat generated by the power distribution equipment on the fixing plate 18 during operation and preventing heat from accumulating at the bottom of the equipment. A sliding block 34 is slidably arranged inside the guide groove 182, and the sliding block 34 can slide along the length direction of the guide groove 182.

[0034] The clamping plate 27 has a support frame 21 on the support block 17. The support frame 21 is elastically connected by a spring. One end of the support frame 21 is provided with a pressure plate 22. Two sliders 16 move closer to each other along the sliding groove 121. The sliders 16 drive the connecting rod 14 to move through the telescopic tube 15. The connecting rod 14 drives the support frame 21 and the pressure plate 22 to move towards each other through the support block 17. The two pressure plates 22 move closer to each other and press tightly against the front and back of the equipment to achieve stable clamping of the front and back of the equipment, which is suitable for equipment of different thicknesses. The fixed plate 18 has fixed plates 26 on both sides of its exterior. Multiple clamping plates 27 are slidably arranged on the fixed plates 26. The side wall of the fixed plate 18 is slidably provided with a telescopic plate 28. One end of the telescopic plate 28 passes through the fixed plate 26 and is rotatably provided with a first rotating plate 29. Square grooves 291 are opened at both ends of the 29. One end of the clamping plate 27 is rotatably provided with a fixed rod 271. A second rotating plate 36 is provided between the two fixed rods 271. The center position of the second rotating plate 36 rotates. A movable rod 362 is provided. Both ends of the first rotating plate 29 are provided with grooves 291 that cooperate with the movable rod 362. Both ends of the clamping plate 27 are provided with square grooves 361. One end of the fixed rod 271 passes into the square groove 361 and slides in cooperation with it. The two telescopic plates 28 approach each other. The telescopic plates 28 drive the first rotating plate 29 to move towards each other. The first rotating plate 29 drives the movable rod 362 to move through the square grooves 291. The movable rod 362 drives the second rotating plate 36 to move. The second rotating plate 36 drives multiple clamping plates 27 to slide towards each other along the fixed plate 26 through the fixed rod 271. The multiple clamping plates 27 approach each other and squeeze and fix the two sides of the equipment. When one of the clamping plates 27 contacts the surface of the equipment and stops moving, the second rotating plate 36 rotates and drives another clamping plate 27 that has not contacted the equipment to continue moving until the clamping plate 27 also makes close contact with the surface of the equipment, thereby realizing adaptive clamping and fixing of the equipment at different positions and adapting to power distribution equipment of different sizes and specifications.

[0035] The transmission mechanism is connected to the telescopic plate 28 and can drive the sliding block 34 to slide along the guide groove 182. The sliding block 34 drives the clamping plate 27 to move through cooperation with the transmission mechanism. Multiple clamping plates 27 squeeze and fix the inserted equipment by approaching each other.

[0036] like Figure 1-8As shown, in a preferred embodiment of the present invention, the transmission mechanism includes a transmission plate 31, a sliding plate 35, and a gear 38. The sliding plate 35 is disposed inside the guide groove 182, and the transmission plate 31 is disposed between the sliding block 34 and the support block 17. Through grooves 183 are provided on both sides of the support disk 18, and a rotating shaft 37 is disposed inside the through groove 183. A gear 38 is disposed outside the rotating shaft 37. Gear grooves 39 that mesh with the gear 38 are provided on both the sliding plate 35 and the telescopic plate 28. The gear 38 simultaneously engages with the sliding plate 35. The gear grooves 39 on the plate 35 and the telescopic plate 28 mesh to form a gear transmission structure. When the two support blocks 17 approach each other, the support blocks 17 drive the sliding blocks 34 to move along the guide groove 182 through the transmission plate 31. The two sliding blocks 34 move away from each other and drive the corresponding sliding plates 35 to move. The sliding plates 35 drive the gears 38 to rotate around the rotating shaft 37 through the gear grooves 39. The rotating gears 38 drive the telescopic plates 28 to move through the gear grooves 39 on the other side, so that the two telescopic plates 28 approach each other, and the clamping plates 27 automatically clamp the two sides of the equipment.

[0037] like Figure 1-7 As shown, in a preferred embodiment of the present invention, a connecting plate 24 is provided on the slider 16, and a lifting plate 23 is provided between the two connecting plates 24. The lifting plate 23 has multiple slots 231. A connecting pipe 20 is provided at the center of the fixed plate 18. A pressure block 19 is provided at the top of the connecting pipe 20, and a pressure rod 33 is provided at the bottom of the connecting pipe 20. A locking block 331 is provided at the bottom of the pressure rod 33. A movable block 32 is provided outside the 23. The locking block 331 passes through the 32 and enters the slot 231. When the power distribution equipment is placed on the fixed plate 18, the equipment's own weight... The pressure block 19 is squeezed, which drives the connecting pipe 20 to descend vertically. The connecting pipe 20 drives the pressure rod 33 and the locking block 331 to descend until the locking block 331 passes through the movable block 32 and enters the corresponding locking groove 231, thereby fixing the lifting plate 23 and the pressure rod 33, thus restricting the left and right sliding of the fixed plate 18 and ensuring the installation stability of the fixed plate 18. At the same time, during the descent of the pressure block 19, the lifting plate 23 is driven to move downward. The lifting plate 23 pulls the two sliders 16 closer to each other along the sliding groove 121 of the crossbeam 12 through the connecting plate 24, thereby realizing the automatic clamping of the front and back of the equipment by the pressure plate 22.

[0038] like Figure 1-6As shown in the preferred embodiment of the present invention, the heat exchange zone 102 is provided with an installation plate 6, on which a fan 9 and a heat exchanger 8 are provided. Cold air pipes 7 are provided on both sides of the cabinet 1. An air outlet pipe 25 is provided on the lifting plate 23. A connector 11 is provided between the air outlet pipe 25 and the cold air pipe 7. When the fan 9 is started, the cold air cooled by the heat exchanger 8 is sent into the cold air pipe 7. The cold air flows upward along the cold air pipe 7 and enters the air outlet pipe 25 through the connector 11. At the same time, the cold air flows into the connecting pipe 20 through the internal channel of the movable block 32. Since the connecting pipe 20 is connected to the heat dissipation groove 181 on the fixed plate 18, the cold air flows from the connecting pipe 20 into the heat dissipation groove 181, thereby achieving heat dissipation at the bottom of the equipment on the fixed plate 18, solving the problem of heat accumulation during equipment operation, and ensuring long-term stable operation of the equipment.

[0039] like Figure 1-2 As shown, in a preferred embodiment of the present invention, the cabinet body 1 is provided with a cabinet door 4, the cabinet door 4 is provided with a handle 3, and the cabinet body 1 is provided with a dustproof net 2.

[0040] like Figure 1-4 As shown, in a preferred embodiment of the present invention, the mounting buckle 13 is provided with a screw 131, one end of which is inserted into the mounting strip 5.

[0041] The above embodiments of the present invention provide a modular heat dissipation distribution cabinet. Loosen the screws 131 on the mounting clip 13, push the mounting clip 13 to slide along the vertical direction of the mounting strip 5 until the height of the crossbeam 12 matches the equipment height, tighten the screws 131, and fix the mounting clip 13 and crossbeam 12 onto the mounting strip 5, completing the installation height adjustment. The distribution equipment to be installed is placed stably on the fixed plate 18. The equipment's own weight presses down on the pressure block 19 in the center of the fixed plate 18. The pressure block 19 drives the connecting pipe 20 to move downwards in the vertical direction. The connecting pipe 20 drives the bottom pressure rod 33 and the clip 331 to descend. During the descent of the pressure block 19, it drives the lifting plate 23 to move downwards. The lifting plate 23 pulls two sliders 16 closer to each other along the sliding groove 121 through the connecting plates 24 on both sides. The sliders 16 drive the connecting... The connecting rods 14 move towards each other, and the connecting rods 14 drive the support frame 21 and the pressure plate 22 to move towards each other through the support block 17 until the two pressure plates 22 are tightly pressed against the front and back of the equipment, realizing the stable clamping of the front and back of the equipment; when the two support blocks 17 approach each other, the transmission plate 31 drives the sliding block 34 to move along the guide groove 182 of the fixed plate 18, the two sliding blocks 34 move away from each other and drive the sliding plate 35 fixedly connected to them to move away from each other synchronously, the two telescopic plates 28 approach each other, and multiple clamping plates 27 slide towards each other along the fixed plate 26 to press and fix the two sides of the equipment, realizing the all-round fixation of the equipment; the heat dissipation system is started, the heat exchanger 8 cools the hot air in the heat exchange zone 102 into cold air, and the fan 9 sends the cooled cold air into the cold air pipes 7 on both sides of the cabinet 1. The cold air flows into the heat dissipation groove 181 from the connecting pipe 20, realizing the heat dissipation of the bottom of the equipment.

[0042] The above description is merely a specific embodiment of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure.
