[0002] The distribution cabinet (box) is divided into power distribution cabinet (box), lighting distribution cabinet (box), and metering cabinet (box). It is the final equipment of the power distribution system. The distribution cabinet is a general term for the motor control center. The distribution cabinet is used in places where the load is relatively dispersed and there are fewer circuits; the motor control center is used in places where the load is concentrated and there are more circuits. They distribute the power of a circuit of the upper-level distribution equipment to the nearest load. This level of equipment should provide protection, monitoring and control for the load.

[0010] As a further description of the above technical solution:

[0011] The two-way cooling component includes an air induced draft box, which is arranged at a position inside the distribution cabinet corresponding to the cabinet heat dissipation port. The air induced draft box is embedded with a draft fan blade, which is fixedly mounted on the output shaft of the electric motor, and the electric motor body is fixedly mounted on the outside of the air induced draft box.

[0012] As a further description of the above technical solution:

[0013] The bidirectional cooling component also includes a heat exchange pipe, which is embedded in the inside of the power distribution cabinet and covers the inside of the power distribution cabinet in all directions.

[0014] As a further description of the above technical solution:

[0015] One end of the heat exchange pipe is connected to an air induced draft pipe which is connected to an air induced draft box, and the other end of the heat exchange pipe is connected to a heat flow release pipe which is clamped on a power distribution cabinet.

[0016] As a further description of the above technical solution:

[0017] An electric push rod is fixedly installed inside the power distribution cabinet body, the output end of the electric push rod is connected to a coupling frame, and the other end of the coupling frame is connected to an air induced draft box. The distance between the air induced draft box and the heat dissipation port of the cabinet body is adjusted by controlling the electric push rod.

[0018] As a further description of the above technical solution:

[0019] The cooling switching assembly includes a sealing box cover, which is slidably connected to the air inlet of the induced draft box. The sealing box cover is connected to a supporting inner shaft, and a supporting outer cylinder is sleeved on the supporting inner shaft. The supporting outer cylinder is connected to the induced draft box, and a supporting spring is arranged inside the supporting outer cylinder for applying elastic tension to the supporting inner shaft.

[0020] As a further description of the above technical solution:

[0021] The sealing box cover is connected with a rope, and the other end of the rope is connected to the inside of the power distribution cabinet body.

[0022] As a further description of the above technical solution:

[0023] The elastic docking assembly includes a water diversion pipe, which is connected to the air induced draft box. The water diversion pipe is connected to a supporting inner tube. The other end of the supporting inner tube is sleeved with a docking sleeve. The docking sleeve is connected to the supporting inner tube through a docking spring. A spherical docking shaft is embedded in the port of the docking sleeve, and a spherical docking port is provided on the spherical surface of the spherical docking shaft.

[0025] The rainwater receiving assembly comprises a rainwater receiving box, which is connected to the cabinet body of the power distribution cabinet through a bracket, and the interior of the rainwater receiving box is connected to a slope panel.

[0026] As a further description of the above technical solution:

[0027] The rainwater receiving box is connected with a drainage pipe, the other end of which extends to the inside of the power distribution cabinet, the drainage pipe is clamped on the power distribution cabinet, and the other end of which is sleeved with a docking inner sleeve.

[0028] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0029] 1. In the present invention, during the process of the sealing box cover completing the sealing of the heat dissipation port of the cabinet and the induced draft box, the induced draft box will also drive the spherical docking shaft on the docking outer sleeve to move in the direction of the docking inner sleeve through the water diversion pipe and the supporting inner pipe. When the spherical docking shaft is connected to the docking inner sleeve, an extrusion force will be generated between the two. Under the action of the extrusion force, the docking outer sleeve slides on the supporting inner tube and squeezes the docking spring to deform it. Then the system controls the solenoid valve on the drainage pipe to open, and the rainwater received in the rainwater receiving box enters the induced draft box through the drainage pipe. The drainage fan blades in a rapidly rotating state can drive the rainwater into the heat exchange pipe. After the rainwater circulates in the heat exchange pipe for one week, it is discharged through the heat flow release pipe, so that the interior of the distribution cabinet can be water-cooled on rainy days, ensuring the sealing of the interior of the distribution cabinet under rainy conditions.

[0030] 2. In the present invention, when it is detected that it is raining outside the distribution cabinet, the electric push rod will pull the air induced draft box toward the heat dissipation port of the cabinet through the connecting frame. During this process, the tension of the rope on the sealing box cover gradually weakens until it disappears. The sealing box cover seals the air induced draft box under the action of the return elastic force of the supporting spring. At the same time, the sealing box cover also seals the heat dissipation port of the cabinet, thereby preventing rainwater and high-humidity air from flowing through the heat dissipation port of the cabinet and entering the interior of the distribution cabinet.

[0031] 3. In the present invention, the operation of the electric motor is controlled. During the operation, the output shaft of the electric motor drives the induced draft fan blades to rotate rapidly. Under the action of the induced draft fan blades, the air outside the distribution cabinet passes through the heat dissipation port of the cabinet and enters the interior of the distribution cabinet. After the air flows in through the heat dissipation port of the cabinet, on the one hand, the air flows through the induced draft duct and enters the heat exchange pipe. After circulating in the heat exchange pipe for one week, the air is discharged through the heat release pipe. On the other hand, the air bypasses the sealing box cover and directly acts on the interior of the distribution cabinet, thereby increasing the scope of air cooling over a larger range. The air cooling effect is more comprehensive, and to a certain extent, the built-in electronic components of the distribution cabinet block the air flow and reduce the air cooling effect.

DETAILED DESCRIPTION

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] See also Figure 1-Figure 10 The present invention provides a technical solution: an anti-seepage outdoor power distribution cabinet, comprising a power distribution cabinet body 1, a cabinet heat dissipation port 2 is provided on the power distribution cabinet body 1, a protective cover 7 having a semi-shielding effect is connected to a position corresponding to the cabinet heat dissipation port 2 on the power distribution cabinet body 1, a two-way cooling component 3 for extracting air through the cabinet heat dissipation port 2 is provided at a position corresponding to the cabinet heat dissipation port 2 inside the power distribution cabinet body 1, and a cooling switching component 4 for blocking the cabinet heat dissipation port 2 is connected to the two-way cooling component 3;

[0046] The two-way cooling component 3 is connected with an elastic docking component 5, and a rainwater receiving component 6 is provided on the distribution cabinet body 1 corresponding to the elastic docking component 5. The two-way cooling component 3 is connected with the rainwater receiving component 6 through the elastic docking component 5 to transform from air cooling to water cooling.

[0047] Specifically, Figure 3-Figure 7 and Figure 9-10As shown, the two-way cooling component 3 includes an induced draft box 301, which is arranged at a position inside the distribution cabinet body 1 corresponding to the cabinet body heat dissipation port 2, and the induced draft box 301 is embedded with a drainage fan blade 302, which is fixedly mounted on the output shaft of the electric motor 303, and the electric motor 303 is fixedly mounted on the outside of the induced draft box 301. The two-way cooling component 3 also includes a heat exchange pipe 305, which is embeddedly connected inside the distribution cabinet body 1, and the heat exchange pipe 305 covers the inside of the distribution cabinet body 1 in all directions. One end of the heat exchange pipe 305 is connected to the induced draft duct 304, and the induced draft duct 304 is connected to the induced draft box 301, and the other end of the heat exchange pipe 305 is connected to the heat flow release pipe 306, and the heat flow release pipe 306 is clamped on the distribution cabinet body 1.

[0048] The specific implementation method is: control the operation of the electric motor 303. During the operation, the output shaft of the electric motor 303 will drive the air guide blades 302 to rotate rapidly. Under the action of the air guide blades 302, the air outside the distribution cabinet body 1 flows through the cabinet body heat dissipation port 2 and enters the distribution cabinet body 1. After the air flows in through the cabinet body heat dissipation port 2, on the one hand, the air flow enters the heat exchange pipe 305 through the air duct 304, and the air flow circulates in the heat exchange pipe 305 for one week and then is discharged through the heat flow release pipe 306. On the other hand, the air flow bypasses the sealing box cover 401 and directly acts on the inside of the distribution cabinet body 1.

[0049] Specifically, Figure 3-Figure 10 As shown, an electric push rod 9 is fixedly installed inside the distribution cabinet body 1, and the output end of the electric push rod 9 is connected to a connecting frame 8, and the other end of the connecting frame 8 is connected to the induced draft box 301. The distance between the induced draft box 301 and the heat dissipation port 2 of the cabinet is adjusted by controlling the electric push rod 9. The cooling switching component 4 includes a sealing box cover 401, and the sealing box cover 401 is slidably connected to the air inlet of the induced draft box 301. A supporting inner shaft 402 is connected to the sealing box cover 401, and a supporting outer cylinder 403 is sleeved on the supporting inner shaft 402. The supporting outer cylinder 403 is connected to the induced draft box 301, and a supporting spring 404 is arranged inside the supporting outer cylinder 403 for applying elastic tension to the supporting inner shaft 402. A rope 405 is connected to the sealing box cover 401, and the other end of the rope 405 is connected to the inside of the distribution cabinet body 1.

[0050] The specific implementation method is as follows: when it is detected that it is raining outside the distribution cabinet 1, the electric push rod 9 will pull the air induced draft box 301 towards the cabinet heat dissipation port 2 through the connecting frame 8. During this process, the pulling force of the rope 405 on the sealing box cover 401 gradually weakens until it disappears. The sealing box cover 401 seals the air induced draft box 301 under the action of the restoring elastic force of the supporting spring 404. At the same time, the sealing box cover 401 also seals the cabinet heat dissipation port 2.

[0051] Specifically, Figure 1-Figure 4 and Figure 7-Figure 10 As shown, the elastic docking assembly 5 includes a water diversion pipe 501, which is connected to the induced draft box 301, and the water diversion pipe 501 is connected to a supporting inner pipe 502, and the other end of the supporting inner pipe 502 is sleeved with a docking jacket 503, and the docking jacket 503 is connected to the supporting inner pipe 502 through a docking spring 504, and a spherical docking shaft 505 is embedded in the port of the docking jacket 503, and a spherical docking shaft 505 is provided on the spherical surface. Interface, the rainwater receiving assembly 6 includes a rainwater receiving box 601, which is connected to the distribution cabinet body 1 through a bracket, and the interior of the rainwater receiving box 601 is connected to a slope panel 602, and the rainwater receiving box 601 is connected to a drainage pipe 603, and the other end of the drainage pipe 603 extends to the inside of the distribution cabinet body 1, and the drainage pipe 603 is clamped on the distribution cabinet body 1, and the other end of the drainage pipe 603 is sleeved with a docking inner sleeve 604.

[0052] The specific implementation method is as follows: when the sealing box cover 401 completes the sealing of the cabinet heat dissipation port 2 and the air induced draft box 301, the air induced draft box 301 will also drive the spherical docking shaft 505 on the docking sleeve 503 to move in the direction of the docking inner sleeve 604 through the water diversion pipe 501 and the supporting inner pipe 502. When the spherical docking shaft 505 is connected with the docking inner sleeve 604, an extrusion force will be generated between the two. Under the action of the extrusion force, the docking sleeve 503 slides on the supporting inner pipe 502 and squeezes the docking spring 504 to deform it. Then the system controls the solenoid valve on the drainage pipe 603 to open, and the rainwater received in the rainwater receiving box 601 enters the air induced draft box 301 through the drainage pipe 603. The drainage fan blades 302 in a fast rotating state can drive the rainwater into the heat exchange pipe 305. After the rainwater circulates in the heat exchange pipe 305 for one week, it is discharged through the heat flow release pipe 306, so that the interior of the distribution cabinet 1 can be water-cooled on rainy days.

[0053] Working principle, when using:

[0054] The electric motor 303 is controlled to run. During the operation, the output shaft of the electric motor 303 drives the air guide blades 302 to rotate rapidly. Under the action of the air guide blades 302, the air outside the cabinet body 1 of the power distribution cabinet flows through the cabinet body heat dissipation port 2 and enters the cabinet body 1 of the power distribution cabinet. After the air flows in through the cabinet body heat dissipation port 2, on the one hand, the air flows through the air guide pipe 304 and enters the heat exchange pipe 305. After circulating in the heat exchange pipe 305 for one week, the air flows out through the heat flow release pipe 306. On the other hand, the air flows around the sealing box cover 401 and directly acts on the cabinet body 1 of the power distribution cabinet, thereby increasing the scope of air cooling over a larger range, making the air cooling effect more comprehensive, and reducing the air cooling effect to a certain extent by reducing the air flow obstruction caused by the built-in electronic components of the cabinet body 1 of the power distribution cabinet.

[0055] When it is detected that it is raining outside the cabinet 1 of the power distribution cabinet, the electric push rod 9 will pull the induced draft box 301 toward the cabinet heat dissipation port 2 through the coupling frame 8. During this process, the pulling force of the rope 405 on the sealing box cover 401 gradually weakens until it disappears. The sealing box cover 401 seals the induced draft box 301 under the action of the restoring elastic force of the support spring 404. At the same time, the sealing box cover 401 also seals the cabinet heat dissipation port 2, thereby preventing rainwater and high-humidity air from flowing through the cabinet heat dissipation port 2 and entering the inside of the power distribution cabinet 1;

[0056] When the sealing box cover 401 completes the sealing of the cabinet heat dissipation port 2 and the air induced draft box 301, the air induced draft box 301 will also drive the spherical docking shaft 505 on the docking sleeve 503 to move in the direction of the docking inner sleeve 604 through the water inlet pipe 501 and the supporting inner tube 502. When the spherical docking shaft 505 is connected with the docking inner sleeve 604, an extrusion force is generated between the two. Under the action of the extrusion force, the docking sleeve 503 slides on the supporting inner tube 502 and squeezes the docking spring 504 to make it Deformation occurs, and then the system controls the solenoid valve on the drainage pipe 603 to open, and the rainwater received in the rainwater receiving box 601 enters the induced draft box 301 through the drainage pipe 603, and the drainage fan blades 302 in a fast rotating state can drive the rainwater into the heat exchange pipe 305, and the rainwater circulates in the heat exchange pipe 305 for one week and then is discharged through the heat flow release pipe 306, so that the interior of the distribution cabinet body 1 can be water-cooled on rainy days, thereby ensuring the sealing of the interior of the distribution cabinet body 1 in rainy days.

[0057] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
