Description

Technical Field

[0001] This utility model relates to the field of heat dissipation technology for power distribution cabinets, specifically a power distribution cabinet equipped with a uniform heat dissipation and cooling mechanism. Background Technology

[0002] Distribution cabinets (boxes) are divided into power distribution cabinets (boxes), lighting distribution cabinets (boxes), and metering cabinets (boxes), and are the final-level equipment in a power distribution system. Distribution cabinets are a general term for motor control centers. Distribution cabinets are suitable for scenarios where the load is relatively dispersed and there are few circuits. Motor control centers are used in situations where the load is concentrated and there are many circuits. They distribute the electrical energy from a circuit of the upstream power distribution equipment to the nearest load. This equipment should provide protection, monitoring, and control for the load.

[0003] Chinese utility model patent CN214227567U discloses a positive pressure explosion-proof distribution cabinet with a uniform heat dissipation and cooling mechanism. The cabinet includes a cabinet body, a dustproof net, and a collection box. A motor is fixed to the cabinet body, and a screw rod is fixed to the end of the motor's output shaft. The screw rod is connected to the cabinet body by a bearing. The collection box is located inside the cabinet body, and a temperature sensor and a protective net are fixed to the cabinet body. The cabinet body is connected to a door via hinges. This positive pressure explosion-proof distribution cabinet with a uniform heat dissipation and cooling mechanism uses a movable heat dissipation mechanism instead of a traditional fixed one, thus enabling comprehensive heat dissipation and cooling of the cabinet body and ensuring effective heat dissipation. Combined with a linked dust-proof cleaning mechanism, it can block and clean dust in real time. A sensor-controlled adjustment mechanism can close the exhaust vents to prevent dust from entering when the cabinet is not in operation.

[0004] While the existing technical solutions described above employ a movable heat dissipation mechanism to comprehensively cool the distribution cabinet body, the movable parts may experience wear, jamming, or malfunction due to prolonged operation. Furthermore, the heat dissipation mechanism, installed inside the distribution cabinet, occupies internal space, resulting in limited internal installation space. Therefore, there is an urgent need to design a distribution cabinet with a uniform heat dissipation mechanism to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a power distribution cabinet with a uniform heat dissipation and cooling mechanism, so as to solve the problem in the above-mentioned background technology that although the movable heat dissipation mechanism can provide comprehensive heat dissipation and cooling for the power distribution cabinet body, the movable parts may wear out, jam or malfunction due to long-term operation. At the same time, the heat dissipation mechanism is installed inside the power distribution cabinet, which will occupy the internal space of the power distribution cabinet, resulting in limited internal installation space.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a power distribution cabinet equipped with a uniform heat dissipation and cooling mechanism, comprising: a cabinet body; a fixed frame fixedly connected to the side surface of the cabinet body; a heat dissipation mechanism movably connected inside the fixed frame; a support base fixedly connected inside the heat dissipation mechanism; a servo motor fixedly connected to the upper surface of the support base; a rotating rod fixedly connected to the output end of the servo motor; a limit block fixedly connected to the outer surface of the rotating rod; a movable rod movably connected to the outer surface of the limit block; a movable groove formed inside the movable rod; a rotating shaft fixedly connected to the side surface of the movable rod; a pulling rod movably connected to the outer surface of the rotating shaft; a cooling fan movably connected to the end of the pulling rod away from the rotating shaft; a guide groove slidably connected to the outer surface of the cooling fan; and the guide groove fixedly connected inside the heat dissipation mechanism.

[0007] Preferably, a stop block is movably connected to the side surface of the fixing frame, a limit plate is fixedly connected to the bottom of the stop block, and a first spring column is fixedly connected to the bottom of the limit plate.

[0008] Preferably, a fixing plate is fixedly connected to the side of the fixing frame away from the cabinet, and a fixing bolt is movably connected to the outer surface of the fixing plate.

[0009] Preferably, a clamping mechanism is movably connected to the outer surface of the fixing plate, and a fixing seat is fixedly connected to the side surface of the clamping mechanism.

[0010] Preferably, a limiting rod is movably connected to the side surface of the fixed base, an outer pull plate is fixedly connected to the outer surface of the limiting rod, and a limiting ball is movably connected to the end of the limiting rod away from the outer pull plate.

[0011] Preferably, a push plate is fixedly connected to the outer surface of the limiting rod, and a second spring column is fixedly connected to the outer surface of the push plate.

[0012] Preferably, the second spring post is sleeved on the outer surface of the limiting rod, one end of the second spring post is fixedly connected to the side surface of the push plate away from the fixed seat, and the other end of the second spring post is fixedly connected to the inner wall of the fixed seat.

[0013] Preferably, a filter screen is movably connected inside the fixed plate, and the filter screen is movably connected to the surface of the fixed frame away from the cabinet.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By setting up a fixing bracket and a heat dissipation mechanism, the heat dissipation mechanism can be installed on the outside of the cabinet through the fixing bracket. With the linkage between the heat dissipation fan and the movable rod, the heat dissipation mechanism can more comprehensively cover the entire heat dissipation area, break the stagnation of hot air, promote the exchange of hot air with external cold air, and enable it to quickly remove more heat and improve the heat dissipation effect.

[0016] The clamping mechanism and limiting rod allow the filter to be easily removed from the mounting plate when cleaning is required. This operation is simple, quick, and efficient, eliminating the need for complex disassembly of the entire distribution cabinet. Furthermore, the removable filter can be optimized and adjusted according to the internal equipment layout and heat source distribution of the cabinet. Since different types of filters may have different air resistance characteristics, the most suitable filter can be selected based on the actual situation to optimize airflow and improve heat dissipation efficiency.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-6 An embodiment of this utility model provides a power distribution cabinet with a uniform heat dissipation and cooling mechanism, comprising: a cabinet body 1, a fixed frame 2 fixedly connected to the side surface of the cabinet body 1, a heat dissipation mechanism 4 movably connected inside the fixed frame 2, a support base 9 fixedly connected inside the heat dissipation mechanism 4, a servo motor 10 fixedly connected to the upper surface of the support base 9, a rotating rod 11 fixedly connected to the output end of the servo motor 10, a limit block 12 fixedly connected to the outer surface of the rotating rod 11, a movable rod 13 movably connected to the outer surface of the limit block 12, a movable groove 14 opened inside the movable rod 13, a rotating shaft 15 fixedly connected to the side surface of the movable rod 13, a pulling rod 16 movably connected to the outer surface of the rotating shaft 15, a cooling fan 17 movably connected to the end of the pulling rod 16 away from the rotating shaft 15, a guide groove 18 slidably connected to the outer surface of the cooling fan 17, and the guide groove 18 fixedly connected inside the heat dissipation mechanism 4.

[0026] Specifically, by setting the guide groove 18, when the pull rod 16 pulls the cooling fan 17 to move up and down along the guide groove 18, the guide groove 18 can play a guiding role, so that the cooling fan 17 can make a fixed vertical reciprocating motion, thereby realizing heat dissipation and cooling at different positions inside the cabinet 1.

[0027] Please see Figure 1-6 A stop block 3 is movably connected to the side surface of the fixed frame 2. A limit plate 23 is fixedly connected to the bottom of the stop block 3. A first spring column 24 is fixedly connected to the bottom of the limit plate 23.

[0028] Specifically, by setting the stop 3, when the heat dissipation mechanism 4 slides into the interior of the fixed frame 2 from the side, the stop 3 can effectively limit the movement and prevent the heat dissipation mechanism 4 from sliding out from the side of the fixed frame 2 during operation.

[0029] Please see Figure 1-6 A fixing plate 5 is fixedly connected to the side of the fixing frame 2 away from the cabinet 1, and a fixing bolt 6 is movably connected to the outer surface of the fixing plate 5.

[0030] Specifically, by setting the fixing bolt 6, the fixing plate 5 can be fixedly connected to the side surface of the fixing frame 2. The fixing plate 5 can also be used independently. When the fixing frame 2 is disassembled, the fixing plate 5 can be fixedly connected to the side surface of the cabinet 1, thereby achieving independent dust isolation of the filter screen 8.

[0031] Please see Figure 1-6 A clamping mechanism 7 is movably connected to the outer surface of the fixing plate 5, and a fixing seat 19 is fixedly connected to the side surface of the clamping mechanism 7.

[0032] Specifically, the fixed base 19 provides support for the movement of the limiting rod 20, allowing the limiting rod 20 to maintain horizontal displacement, thereby effectively improving the stability of the device.

[0033] Please see Figure 1-6 A limiting rod 20 is movably connected to the side surface of the fixed seat 19. An outer pull plate 21 is fixedly connected to the outer surface of the limiting rod 20. A limiting ball 22 is movably connected to the end of the limiting rod 20 away from the outer pull plate 21.

[0034] Specifically, by setting the outer pull plate 21, the operator can exert more force when the limit rod 20 is pulled outward, thus making it easier to pull the limit rod 20.

[0035] Please see Figure 1-6 A push plate 25 is fixedly connected to the outer surface of the limiting rod 20, and a second spring column 26 is fixedly connected to the outer surface of the push plate 25.

[0036] Specifically, by setting the second spring post 26, after the limiting rod 20 is displaced in the direction of the outward pulling plate 21, the second spring post 26 can push the limiting rod 20 back to its original position, thereby facilitating the next displacement of the limiting rod 20.

[0037] Please see Figure 1-6 The second spring post 26 is sleeved on the outer surface of the limiting rod 20. One end of the second spring post 26 is fixedly connected to the side surface of the push plate 25 away from the fixed seat 19, and the other end of the second spring post 26 is fixedly connected to the inner wall of the fixed seat 19.

[0038] Specifically, by setting the push plate 25, the center of the push plate 25 is fixedly connected to the outer surface of the limit rod 20. After the limit rod 20 is displaced upward, the push plate 25 will push the limit rod 20 to reset.

[0039] Please see Figure 1-6 The fixed plate 5 has a filter screen 8 movably connected inside, and the filter screen 8 is movably connected to the surface of the fixed frame 2 away from the cabinet 1.

[0040] Specifically, the filter screen 8 can be slidably removed from one side of the fixing plate 5, making it very convenient to disassemble and clean the filter screen 8, thereby greatly improving cleaning efficiency.

[0041] Working principle: In use, first fix the mounting bracket 2 to the side surface of the cabinet 1. Slide the heat dissipation mechanism 4 into the mounting bracket 2 from the side. The stop block 3 limits and fixes the sliding heat dissipation mechanism 4. Then fix the mounting plate 5 to the side surface of the mounting bracket 2 away from the cabinet 1 using the fixing bolt 6. Push the filter screen 8 into the side surface of the mounting plate 5. During the process of pushing the filter screen 8 in, the filter screen 8 will push the limiting ball 22 to the side of the outward pull plate 21. When the filter screen 8 is pushed into the appropriate position, the limiting ball 22, under the action of the second spring column 26, will push the limiting ball 22 to clamp the outer surface of the filter screen 8, thereby realizing the cooling effect. The filter screen 8 has a limiting and fixing function; then the servo motor 10 is started, so that the servo motor 10 drives the rotating rod 11 to rotate in a circle, and the movable rod 13 is sleeved on the limiting block 12 at the end of the rotating rod 11 away from the servo motor 10. When the limiting block 12 is driven by the rotating rod 11, the movable rod 13 will also drive the rotating shaft 15 to produce displacement. Since the rotating shaft 15 is movably connected between the movable rod 13 and the pulling rod 16, and the second spring column 26 is also rotatably connected to the side surface of the cooling fan 17, the pulling rod 16 pulls the cooling fan 17 to move up and down along the guide groove 18, thereby achieving uniform heat dissipation over a large area.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
