Description

Technical Field

[0001] This invention belongs to the field of communication power cabinet technology, specifically, it relates to a communication cabinet with a current diversion function. Background Technology

[0002] The components in the power cabinet generate a lot of heat during operation, which raises the temperature inside the cabinet. High temperatures can affect the performance of the components, shorten their lifespan, and even cause them to malfunction. Therefore, it is necessary to install fans in the power cabinet for heat dissipation. The existing fans are installed at the air inlet in the power cabinet, blowing air inward and exhausting it directly through the outlet.

[0003] Chinese patent CN216981280U discloses a heat dissipation structure and an electrical cabinet. The structure comprises a base, a protective cover, and at least one cooling fan. The base serves as the top cover of the cabinet and has mounting holes that communicate with the interior of the cabinet. The protective cover covers the mounting holes on the base, forming a receiving cavity with the mounting holes. The mounting holes communicate with the receiving cavity. The cooling fan is located within the receiving cavity. The protective cover prevents dust or water from entering the cabinet. The sides of the protective cover have ventilation holes that also communicate with the receiving cavity. Hot air inside the cabinet is expelled through the mounting holes, the receiving cavity, and the ventilation holes in sequence, driven by the cooling fan. This arrangement of the ventilation holes on the sides of the protective cover allows for heat dissipation while preventing dust or water from falling into the cabinet from the top.

[0004] However, this technical solution still has at least the following drawbacks: the heat dissipation holes in the device lead directly into the electrical cabinet; if the cooling fan operates at low power, dust may still enter the electrical cabinet through the heat dissipation holes and adhere to the components. Furthermore, this technical solution lacks a cleaning function for the heat dissipation holes. Therefore, this invention is proposed. Summary of the Invention

By setting a first flow guiding structure and a second flow guiding structure, the hot air blown by the fan is guided so that it can be discharged smoothly. By setting an electric cylinder to drive the flow guiding plate to rotate, the heat dissipation effect can be adjusted.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention.

[0020] Example 1 like Figures 1 to 10 As shown, a communication cabinet with a flow guiding function includes a fan 108, and also includes: A first housing 100 includes a first flow guiding structure, which includes a first flow guiding surface 101 and a second flow guiding surface 102. The second housing 104 includes a second flow guiding structure, which includes a third flow guiding surface 105, a fourth flow guiding surface 106, and a fifth flow guiding surface 107. The air blown out by the fan 108 enters the space on one side of the second guide surface 102 through the guiding effect of the fifth guide surface 107, the fourth guide surface 106 and the third guide surface 105, and is discharged through the guiding effect of the second guide surface 102 and the first guide surface 101.

[0021] like Figures 1 to 3 As shown, in a specific embodiment, the third guide surface 105 and the fifth guide surface 107 are inclined, the fourth guide surface 106 is located between the third guide surface 105 and the fifth guide surface 107, the first guide surface 101 is inclined, the second guide surface 102 is located at one top end of the first guide surface 101, and a baffle 103 is installed at one end of the second guide surface 102. In this configuration, a heat dissipation hole is provided at the top of the second housing 104, and the hot airflow is discharged along the heat dissipation hole under the guidance of the first guide surface 101.

[0022] The communication cabinet is fixedly installed with sealing plates 109 on both sides of the fan 108. The sealing plates 109 are used to prevent the hot air extracted by the fan 108 from flowing back. The guiding effect of the first guide surface 101 and the second guide surface 102 can also prevent rainwater from entering and play the role of draining rainwater.

[0023] like Figures 1 to 3 As shown, furthermore, it also includes an adjustment unit, which includes a guide plate 205 rotatably mounted on the top of the inner wall of the second housing 104. The adjustment unit also includes a drive mechanism and a lifting mechanism. The drive mechanism includes an electric cylinder 200 fixedly mounted on the top of the second housing 104. The lifting mechanism is connected to the output end of the electric cylinder 200. The electric cylinder 200 drives the guide plate 205 to rotate and adjust its tilt through the lifting mechanism. In this configuration, the output shaft of the electric cylinder 200 is limited by a limiting device to prevent it from rotating.

[0024] like Figures 3 to 5 As shown, the lifting mechanism further includes a guide block 201 and a movable frame 203. The guide block 201 is fixedly installed at the output end of the electric cylinder 200. Limiting tubes 202 are movably sleeved on both sides of the movable frame 203. The bottom of the limiting tubes 202 is fixedly installed on the top of the second housing 104. The two sides of the movable frame 203 movably pass through the second housing 104. A reset component is provided on the bottom of one side of the movable frame 203. In this configuration, the limiting tubes 202 are used to keep the movable frame 203 moving in the horizontal direction.

[0025] like Figures 4 to 6As shown, further, a connecting rod 204 is rotatably mounted on the bottom of the other side of the movable frame 203. The bottom of the connecting rod 204 is rotatably mounted on the top of the guide plate 205. The reset assembly includes a spring 207 movably sleeved on the movable frame 203. A fixing block 206 is fixedly mounted on one bottom end of the movable frame 203. The elastic force of the spring 207 acts on the fixing block 206 so that when the electric cylinder 200 drives the guide block 201 to move, the movable frame 203 can closely adhere to the top of the guide block 201. In this configuration, when the guide block 201 moves, its different positions have different heights at the movable frame 203, so that the movable frame 203 can perform lifting and lowering movements. During the lifting and lowering movements, the connecting rod 204 drives the guide plate 205 to rotate to achieve angle adjustment.

[0026] like Figures 6 to 7 As shown, further, a cleaning unit is also included. The cleaning unit includes an air storage mechanism, which includes an air pipe 300. Mounting brackets 301 are movably fitted to both ends of the air pipe 300. The mounting brackets 301 are fixedly mounted on the top of the second housing 104. A piston 303 is movably mounted inside the air pipe 300. A guide protrusion 302 is formed on the inner wall of the air pipe 300. A guide groove 304, adapted to the guide protrusion 302, is formed on the side wall of the piston 303. The path of the guide protrusion 302 is spiral. When the piston 303 moves along the air pipe 300, it drives the air pipe 300 to rotate through the guide groove 304 and the guide protrusion 302. In this configuration, a sealing ring is installed on the piston 303 to increase sealing. The guide protrusion 302 rotates once within the moving area of ​​the piston 303, so that when the piston 303 moves to the end of the air pipe 300, the air pipe 300 rotates once. A bearing is installed between the mounting bracket 301 and the air pipe 300 to reduce frictional resistance.

[0027] like Figure 6 As shown, further, a connecting frame 305 is fixedly mounted on one end of the piston 303. A groove 306 is formed on the connecting frame 305. A stop rod 307 is fixedly mounted on the output end of the electric cylinder 200. The stop rod 307 is movably connected within the groove 306. The length of the groove 306 is consistent with the length of the guide block 201 along the output direction of the electric cylinder 200. When the moving frame 203 moves along the guide block 201, the stop rod 307 slides within the groove 306 and does not push the connecting frame 305 to move. In this configuration, the output end of the electric cylinder 200 drives the stop rod 307 to move. When the stop rod 307 begins to push the connecting frame 305 to move, the moving frame 203 is misaligned with the guide block 201.

[0028] like Figure 7 , Figure 9As shown, the cleaning unit further includes a blowing mechanism, which includes an outer tube 400 fixedly installed on the top of the second housing 104. An inner tube 402 is movably installed inside the outer tube 400. A straight groove 401 is formed on one side of the outer tube 400, and a spiral groove 403 is formed on the side wall of the inner tube 402. The straight groove 401 and the spiral groove 403 intersect to form an air outlet. When the inner tube 402 drives the spiral groove 403 to rotate, the air outlet formed by the overlapping section of the spiral groove 403 and the straight groove 401 moves along the direction of the straight groove 401. In this configuration, the area of ​​the air outlet formed by the overlapping section of the spiral groove 403 and the straight groove 401 is smaller than the cross-sectional area of ​​the air pipe 300. When the piston 303 moves and squeezes the gas inside the air pipe 300, the blowing speed at the air outlet is relatively high, thereby obtaining a stronger cleaning ability.

[0029] like Figures 7 to 8 As shown, further, one end of the inner tube 402 has an air inlet groove 404, and one end of the outer tube 400 is equipped with a transition cavity 405. The transition cavity 405 is aligned with the air inlet groove 404. A connecting pipe 406 is fixedly installed at one end of the transition cavity 405, and a connector 407 is fixedly installed at one end of the connecting pipe 406. The bottom of the connector 407 is fixedly installed on the top of the second housing 104, and the connector 407 is sealed to one end of the air pipe 300. In this configuration, a one-way valve is installed at the connector 407 so that air enters through the one-way valve when the piston 303 resets.

[0030] like Figure 7 , Figure 10 As shown, a transmission mechanism is further provided between the trachea 300 and the outer tube 400. The transmission mechanism includes a rotating shaft 409, which is rotatably connected to one side of the mounting bracket 301. A support member 410 is also movably connected to the rotating shaft 409. The support member 410 is fixedly installed on the top of the second housing 104. A first transmission assembly 408 is installed between one end of the rotating shaft 409 and the trachea 300, and a second transmission assembly 411 is installed between the other end of the rotating shaft 409 and the inner tube 402. In this configuration, both the first transmission assembly 408 and the second transmission assembly 411 are composed of belts and pulleys. The pulleys connected to both ends of the rotating shaft 409 have the same diameter, and the pulleys connected to the trachea 300 and the inner tube 402 have the same diameter.

[0031] Example 2 A communication cabinet with a flow guiding function further includes a processor, wherein the processor is configured with a control system for controlling the movement of the electric cylinder 200, the control system comprising: The input module is used to input cleaning instructions; The assignment module includes: The adjustment mode is used to control the extension and retraction of the electric cylinder 200 to adjust the angle of the guide vane 205; Cleaning mode, used to control the extension and retraction of the electric cylinder 200 to clean the second housing 104; It also includes dividing the stroke of the electric cylinder 200 into regions, including an adjustment section and a cleaning section. The adjustment section represents the movement range of the output end of the electric cylinder 200 when the moving frame 203 is at the top of the guide block 201, and the cleaning section represents the movement range of the output end of the electric cylinder 200 when the piston 303 moves in the air pipe 300. The input module includes a judgment strategy, which changes the working mode of the electric cylinder 200 based on the judgment strategy. When no cleaning command is received, the electric cylinder 200 enters the adjustment mode, and when a cleaning command is received, the electric cylinder 200 enters the cleaning mode. The adjustment mode includes obtaining the rotation angle of the guide plate 205 and the temperature of the hot air blown out by the fan 108, and adjusting the rotation angle of the guide plate 205 based on the hot air temperature. The adjustment mode also includes controlling the electric cylinder 200 to move in the adjustment section. When the hot air temperature is high, the guide plate 205 is rotated to one side by driving the electric cylinder 200 to enhance heat dissipation. When the hot air temperature is low, the guide plate 205 is rotated to the other side by driving the electric cylinder 200 to enhance the hot air velocity. The cleaning mode includes controlling the electric cylinder 200 to move within the cleaning section, and also includes controlling the electric cylinder 200 to perform a reciprocating motion within the cleaning section when a cleaning command is received.

[0032] The implementation principle of a communication cabinet with a flow guiding function in this embodiment is as follows: When working, the fan 108 draws out the hot air in the communication cabinet and blows it out to the fifth flow guiding surface 107. The hot air flows along the fourth flow guiding surface 106 and the third flow guiding surface 105 into the space on one side of the second flow guiding surface 102, and is discharged under the guidance of the first flow guiding surface 101. When the temperature is low, the electric cylinder 200 extends and moves the guide block 201. During the movement of the guide block 201, the spring 207 presses against the fixed block 206 to keep the moving frame 203 pressed against the guide block 201, thereby moving the moving frame 203. During the movement, the connecting rod 204 moves the guide plate 205. The gap between the guide plate 205 and the second guide surface 102 decreases. The hot air enters the second guide surface 102 through the action of the guide plate 205 and is discharged along the first guide surface 101. The reduced gap between the guide plate 205 and the second guide surface 102 increases the airflow speed. Similarly, when the temperature is high, the electric cylinder 200 retracts to increase the gap between the guide plate 205 and the second guide surface 102, thereby enhancing the heat dissipation effect. When cleaning is required at the first housing 100, the electric cylinder 200 is extended. When the electric cylinder 200 drives the stop bar 307 to abut against the connecting frame 305, the electric cylinder 200 continues to extend. At this time, the moving frame 203 abuts against the output end of the electric cylinder 200. In this state, the guide plate 205 maintains the maximum tilt angle, that is, the gap between it and the second guide surface 102 is the smallest. While the electric cylinder 200 continues to move, it pushes the piston 303 to move. During the movement, the piston 303 squeezes the air inside the air pipe 300 and enters the connecting pipe 406 through the connector 407. Then, it enters the inner pipe body 402 through the transition cavity 405 and the air inlet groove 404. The air is blown towards the second housing 104 through the air outlet formed by the overlapping section of the straight groove 401 and the spiral groove 403. During the movement of piston 303, under the dual action of guide protrusion 302 and guide groove 304, air pipe 300 will rotate. During the rotation, the first transmission assembly 408 drives the rotating shaft 409 to rotate. The rotating shaft 409 drives the inner tube body 402 to rotate through the second transmission assembly 411. During the rotation of inner tube body 402, the spiral groove 403 will rotate. During the rotation, the overlapping section of spiral groove 403 and straight groove 401 will move, thereby moving the air outlet to clean different areas of the second housing 104.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
