PLC power distribution cabinet can adapt to various industrial automation control occasions of various sizes. PLC power distribution cabinet is widely used in industries such as power, metallurgy, chemical industry, papermaking, environmental protection and sewage treatment.

[0003] According to a high-efficiency heat dissipation and energy-saving low-voltage distribution cabinet disclosed in Chinese patent announcement No. CN218242741U, this patent can simultaneously supply and exhaust air to the low-voltage distribution cabinet through the first fan blade and the second fan blade, speed up the exchange rate of the low-voltage distribution cabinet with the outside gas, and can efficiently discharge the heat in the low-voltage distribution cabinet to avoid heat accumulation in the low-voltage distribution cabinet, reduce the aging rate of internal components of the low-voltage distribution cabinet, and increase the service life. Through the temperature sensor and the controller, when there is no need to cool down, the first motor and the second motor can be intelligently controlled to be shut down, which is more energy-saving and environmentally friendly.

[0004] Although this patent achieves heat dissipation, according to the technical solution and drawings of the patent, this patent only uses simple fan blades for heat dissipation and cannot communicate and change the direction of wind to quickly distribute the wind inside the cabinet. Therefore, the heat dissipation method achieved by this patent is inefficient.

[0005] Therefore, it is necessary to design a practical, efficient, heat-dissipating and energy-saving distribution cabinet. Summary of the invention

[0006] The purpose of the present invention is to provide a high-efficiency heat dissipation and energy-saving power distribution cabinet to solve the problems raised in the above background technology.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions: a high-efficiency heat dissipation and energy-saving power distribution cabinet, comprising: The cabinet has a heat dissipation vent on the left side; A heat dissipation component is arranged in the cabinet and mounted on the inner wall of the cabinet. A partition is arranged in front of the heat dissipation component and the partition is fixedly mounted on the inner wall of the cabinet. A dust isolation component is arranged at the heat dissipation port, and the dust isolation component is connected to the heat dissipation component; The cleaning component is arranged on the right side of the dust isolation component, and the cleaning component is installed with the inner wall of the cabinet.

[0008] According to the above technical solution, a cabinet door is hingedly installed on the front of the cabinet, and a base is fixedly installed on the bottom of the cabinet. The base installed on the bottom of the cabinet can provide a stable support for the cabinet, and at the same time, it can prevent the bottom of the cabinet from directly contacting the ground, which can play a certain moisture-proof role relative to the ground.

[0009] According to the above technical solution, the heat dissipation component includes: The right end surface of the motor is fixedly installed with the inner wall of the cabinet; The right end of the short shaft is fixedly mounted on the output end of the motor, and the outer wall of the short shaft away from the end of the motor is fixedly mounted with a fan blade.

[0010] According to the above technical solution, the heat dissipation component also includes: An upper gear is fixedly sleeved on the outer wall of the short shaft, and the upper gear is meshed with the lower gear; The right end of the connecting shaft is rotatably arranged with the inner wall of the cabinet through a bearing, and the outer wall of the connecting shaft is fixedly installed with the inner wall of the lower gear; The air guide plate is tilted, and the movable sleeve of the air guide plate is provided with a mounting shaft, and the rear end of the mounting shaft is fixedly mounted on the inner wall of the cabinet; An auxiliary column, the right end of which is in contact with the left end of the connecting shaft, the lower surface of the auxiliary column is fixedly mounted on the upper end of the air guide plate, a short column is slidingly sleeved on the left end of the auxiliary column, the left end of the short column is fixedly mounted on the inner wall of the cabinet, and a first spring is fixedly mounted on the right end of the short column, and the right end of the first spring is fixedly mounted on the inner wall of the auxiliary column.

[0011] According to the above technical solution, there are multiple air guide plates, which are arranged at equal intervals. The surface of the air guide plates has a porous setting. By setting the surface of the air guide plates porous, the wind direction can be changed again during the deflection of the air guide plates, so that the wind can quickly blow to multiple parts of the cabinet, thereby accelerating the heat dissipation speed.

[0012] According to the above technical solution, the end faces of the auxiliary column and the connecting shaft that contact each other are both inclined surfaces. This arrangement is to enable the auxiliary column to be squeezed during the rotation of the connecting shaft, so that the auxiliary column moves and the direction of the air guide plate is changed.

[0013] According to the above technical solution, the dust isolation component includes: A dust-proof plate is arranged in the cabinet, and a U-shaped plate is arranged on the left side of the dust-proof plate in contact with the inner wall of the heat dissipation port; A guide rail plate is fixedly mounted on the inner wall of the cabinet, a slide bar is slidably arranged on the guide rail plate, a distance is set between the right side of the slide bar and the inner wall of the guide rail plate, a second spring is fixedly mounted on the bottom of the slide bar, and the bottom end of the second spring is fixedly mounted on the bottom of the inner wall of the guide rail plate; The upper end of the connector is fixedly mounted on the outer wall of the auxiliary column, and the lower end of the connector is fixedly mounted on the top surface of the dust-shielding plate. The upper end and the lower end of the connector are both made of rubber material.

[0014] According to the above technical solution, a plurality of grooves arranged at equal intervals are provided on the left side of the guide rail plate, and a hemispherical block is clamped in the groove. The hemispherical block is fixedly mounted on the inner wall of the guide rail plate. Through the arrangement of the grooves and the hemispherical block, the dust shielding plate can have a micro-vibration in the left and right directions during the up and down movement of the dust shielding plate, thereby enhancing the falling of dust on the dust shielding plate.

[0015] According to the above technical solution, a baffle is arranged below the dust screen, and a collection box is slidably arranged between the baffle and the inner wall of the cabinet. The baffle can make the dust falling from the dust screen fall into the collection box for centralized treatment.

[0016] According to the above technical solution, the cleaning component includes: The rear end of the mounting column is fixedly mounted on the inner wall of the cabinet; The arc plate is installed with the outer wall of the mounting column through the third spring. The outer wall of the arc plate is fixedly provided with bristles contacting the surface of the dust-shielding plate. The bristles are located between each row of heat dissipation holes of the dust-shielding plate.

[0017] Compared with the prior art, the beneficial effects achieved by the present invention are: 1. The present invention can achieve heat dissipation inside the cabinet by setting a heat dissipation component to prevent the electrical components inside the cabinet from being damaged by high temperature. In particular, the cooperation between the set air guide plate, the upper gear, the lower gear, the connecting shaft, the auxiliary column, and the first spring can change the wind direction of the air guide plate and accelerate the heat dissipation speed.

[0018] 2. The present invention provides a porous surface of the air guide plate, so that the wind direction can be changed again during the deflection of the air guide plate, so that the wind can be quickly blown to multiple parts of the cabinet, and the heat dissipation speed can also be accelerated.

[0019] 3. The present invention can squeeze the dust shielding plate by means of the connecting rod when the auxiliary column moves back and forth. Due to the setting of the second spring, the dust shielding plate can be slightly vibrated up and down to make the dust attached to the dust shielding plate fall off, thereby avoiding affecting the heat dissipation effect.

[0020] 4. The present invention can make the dust shield plate have micro-vibration in the left and right directions during the up and down movement of the dust shield plate by setting the grooves and the spherical blocks, thereby enhancing the dust falling off the dust shield plate and allowing the dust shield plate to normally isolate dust and dissipate heat.

[0021] 5. The present invention can generate friction when the dust shielding plate moves up and down by setting the bristles, so as to clean the dust shielding plate and strengthen the dust treatment. Then, the third spring can be set to make the arc plate vibrate slightly to shake off the dust on the bristles, so as to avoid affecting the cleaning force of the dust shielding plate.

DETAILED DESCRIPTION

[0024] 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.

[0025] Example 1: Please refer to Figure 1-9 The present invention provides a technical solution: a high-efficiency heat dissipation and energy-saving power distribution cabinet, comprising: The cabinet 1 has a heat dissipation port on its left side, a cabinet door 2 is hingedly mounted on the front of the cabinet 1, and a base 3 is fixedly mounted on the bottom of the cabinet 1. The base 3 mounted on the bottom of the cabinet 1 can provide a stable support for the cabinet 1, and can prevent the bottom of the cabinet 1 from directly contacting the ground, thereby providing a certain degree of moisture-proofing relative to the ground. The heat dissipation component 5 is arranged in the cabinet 1 and is installed with the inner wall of the cabinet 1. A partition 4 is arranged in front of the heat dissipation component 5, and the partition 4 is fixedly installed with the inner wall of the cabinet 1. The dust isolation component 6 is arranged at the heat dissipation port, and the dust isolation component 6 is connected to the heat dissipation component 5; The cleaning component 7 is arranged on the right side of the dust isolation component 6 , and the cleaning component 7 is installed with the inner wall of the cabinet 1 .

[0026] The heat dissipation component 5 includes: The right end surface of the motor 51 is fixedly mounted on the inner wall of the cabinet 1; The short shaft 52 has its right end fixedly mounted to the output end of the motor 51 , and a fan blade 53 is fixedly mounted on the outer wall of the short shaft 52 at one end away from the motor 51 .

[0027] In the specific implementation process, the short shaft 52 can be rotated by starting the motor 51, and the fan blades 53 can be rotated under the rotation of the short shaft 52 to form wind force, which can then be blown into the cabinet 1 to achieve the purpose of heat dissipation inside the cabinet 1.

[0028] In this embodiment, the heat dissipation component 5 further includes: An upper gear 54 is fixedly sleeved on the outer wall of the short shaft 52, and the upper gear 54 is meshed with a lower gear 55; The right end of the connecting shaft 56 is rotatably arranged with the inner wall of the cabinet 1 through a bearing, and the outer wall of the connecting shaft 56 is fixedly installed with the inner wall of the lower gear 55; The air guide plate 58 is tilted and is movably sleeved with a mounting shaft 59, the rear end of which is fixedly mounted to the inner wall of the cabinet 1; The right end of the auxiliary column 57 is in contact with the left end of the connecting shaft 56, and the end surfaces of the auxiliary column 57 and the connecting shaft 56 that contact each other are both inclined surfaces. This arrangement is to enable the connecting shaft 56 to be squeezed with the auxiliary column 57 during the rotation process, so that the auxiliary column 57 can move, which is convenient for changing the direction of the air guide plate 58. The lower surface of the auxiliary column 57 is fixedly installed on the upper end of the air guide plate 58, and the left end of the auxiliary column 57 is slidably sleeved with a short column 510, and the left end of the short column 510 is fixedly installed on the inner wall of the cabinet 1, and the right end of the short column 510 is fixedly installed with a first spring 511, and the right end of the first spring 511 is fixedly installed on the inner wall of the auxiliary column 57.

[0029] Here, the upper gear 54 will rotate along with the short shaft 52, and then can drive the lower gear 55 to rotate. Since the end faces where the connecting shaft 56 and the auxiliary column 57 contact each other are set as inclined surfaces, the auxiliary column 57 will be squeezed, and then with the cooperation of the first spring 511, the auxiliary column 57 can be realized to reciprocate horizontally, which can drive the air guide plate 58 to deflect repeatedly and change the air guide direction multiple times, so that the wind can be quickly introduced into various places inside the cabinet 1, thereby accelerating the heat dissipation speed.

[0030] Furthermore, there are multiple air guide plates 58 which are arranged at equal intervals. The surface of the air guide plates 58 has a porous arrangement. By making the surface of the air guide plates 58 porous, the wind direction can be changed again during the deflection of the air guide plates 58, so that the wind can quickly blow to multiple parts of the cabinet 1, thereby accelerating the heat dissipation speed.

[0031] Example 2: Based on the above embodiment, the dust isolation component 6 includes: A dust shield 61 is arranged in the cabinet 1. A U-shaped plate 62 is arranged on the left side of the dust shield 61. The U-shaped plate 62 is fixedly installed on the inner wall of the heat dissipation port. A baffle 8 is arranged below the dust shield 61. A collection box 9 is slidably arranged between the baffle 8 and the inner wall of the cabinet 1. The baffle 8 can make the dust falling from the dust shield 61 fall into the collection box 9 for centralized treatment. The guide plate 63 is fixedly mounted on the inner wall of the cabinet 1, and a slide bar 64 is slidably arranged on the guide plate 63, and a distance is set between the right side of the slide bar 64 and the inner wall of the guide plate 63, and a second spring 68 is fixedly mounted on the bottom of the slide bar 64, and the bottom end of the second spring 68 is fixedly mounted on the bottom of the inner wall of the guide plate 63; The upper end of the connecting body 65 is fixedly mounted to the outer wall of the auxiliary column 57, and the lower end of the connecting body 65 is fixedly mounted to the top surface of the dust shielding plate 61. The upper end and the lower end of the connecting body 65 are both made of rubber material.

[0032] During the specific implementation process, the reciprocating movement of the auxiliary column 57 can cause the connecting rod 65 to repeatedly squeeze the dust shielding plate 61. Due to the setting of the second spring 68, the dust shielding plate 61 can be slightly vibrated up and down, so that the dust attached to the dust shielding plate 61 can fall off and enter the collection box 9, thereby preventing the dust shielding plate 61 from being blocked by dust and affecting the heat dissipation effect.

[0033] In this embodiment, a plurality of grooves 67 arranged at equal intervals are provided on the left side of the guide plate 64, and a hemispherical block 66 is clamped in the groove 67. The hemispherical block 66 is fixedly mounted on the inner wall of the guide plate 63. The arrangement of the grooves 67 and the hemispherical block 66 can make the dust shield plate 61 have a micro-vibration in the left and right directions during the up and down movement of the dust shield plate 61, thereby enhancing the dust falling off the dust shield plate 61.

[0034] Example 3: Based on the above embodiment, the cleaning component 7 includes: The rear end of the mounting column 71 is fixedly mounted to the inner wall of the cabinet 1; The arc plate 72 is mounted on the outer wall of the mounting column 71 via a third spring 73. The outer wall of the arc plate 72 is fixedly mounted with bristles (the bristles are not shown in the figure) that are in contact with the surface of the dust shielding plate 61. The bristles are located between each row of heat dissipation holes of the dust shielding plate 61.

[0035] In the specific implementation process, since the bristles are in contact with the side of the dust shielding plate 61, they rub against the bristles when the dust shielding plate 61 moves up and down, and then the dust shielding plate 61 can be cleaned to strengthen the dust handling. The third spring 73 can make the arc plate 72 vibrate slightly, so that the dust on the bristles falls into the collection box 9 together, avoiding the cleaning force of the bristles on the dust shielding plate 61 in the later stage.

[0036] Working principle: During the operation of the electrical components inside the cabinet 1, the motor 51 can be started to rotate the short shaft 52. The rotation of the short shaft 52 can make the fan blades 53 rotate to generate wind force and achieve the purpose of heat dissipation. At the same time, the upper gear 54 installed on the outer wall of the short shaft 52 will also rotate, which can then make the lower gear 55 rotate. The rotation of the lower gear 55 can make the connecting shaft 56 rotate. Since the contact surface between the connecting shaft 56 and the auxiliary column 57 is an inclined surface, and the short column 510 and the first spring 511 are set, the lateral reciprocating movement of the auxiliary column 57 can be achieved. Since the air guide plate 63 is movably mounted on the outer wall of the mounting shaft 59 and fixedly mounted on the lower surface of the auxiliary column 57, the air guide plate 63 can be repeatedly deflected, so that the wind force can be quickly dispersed to various parts of the cabinet 1 from different angles, so as to speed up the heat dissipation speed. Since the connecting rod 65 is installed on the dust shield 61 and the auxiliary column 57, and the dust-shielding plate 61 is slidably arranged by the sliding rod 64 and the guide plate 63, so the dust-shielding plate 61 can realize up and down micro-vibration under the setting of the first spring 511. Here, due to the groove 67 and the hemispherical block 66, the dust-shielding plate 61 can be micro-vibrated up and down while also realizing left and right micro-vibration, which can enhance the falling of dust on the surface of the dust-shielding plate 61 and finally fall into the collecting box 9. When the dust-shielding plate 61 is micro-vibrated, it can generate friction with the bristles to enhance the cleaning of the surface of the dust-shielding plate 61. At the same time, the arc plate 72 can be micro-vibrated by the third spring 73, and then the bristles can be micro-vibrated to avoid dust accumulation on the surface of the bristles and affect the cleaning force of the dust-shielding plate 61 in the later stage. When the dust in the collecting box 9 needs to be processed, it is only necessary to open the cabinet door 2 and take out the collecting box 8 for cleaning.
