Description

Technical Field

[0001] The invention relates to the field of frequency conversion control cabinets, and more specifically, to an outdoor frequency conversion control cabinet. Background Art

[0002] Frequency conversion control cabinets are mainly used for automatic circuit control in industrial and agricultural production, water supply and drainage, fire protection, HVAC hot and cold water circulation and other occasions of various buildings. Its function is to adjust the working frequency of the equipment, reduce the energy loss of power equipment, and reduce the damage to the motor caused by the large current generated when the equipment is directly started, thereby improving the stability of the equipment when it is started;

[0003] The frequency conversion control cabinet is equipped with a variety of electrical components such as frequency converters, circuit breakers and controllers. These electrical components will generate heat when working for a long time. Excessive heat will affect the operating stability of the electrical components. In order to solve this problem, the control cabinets in the prior art mostly use cooling fans to ventilate and dissipate heat inside the control cabinet. For example, Chinese patent No. CN110513315B discloses an energy-saving frequency conversion control cabinet, which dissipates heat from the electrical components inside the control cabinet through the swing of the cooling fan, thereby improving the heat dissipation efficiency of the frequency conversion control cabinet.

[0004] However, in the high humidity areas along the southern coast of my country, especially in spring and summer, serious condensation is likely to occur in the air. When the existing frequency conversion control cabinet is installed and used in coastal areas, the moisture in the air will enter the control cabinet with the cooling fan and form condensation on the surface of the electrical components. The condensation drips onto the metal parts inside the control cabinet, causing the metal parts to rust. At the same time, the condensation drips onto the electrical components, causing electrical short circuits, explosions and other problems. In addition, the insulation performance of electrical components will decrease if they operate in a high humidity environment for a long time, which will shorten the service life of the components.

[0041] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0042] See also Figures 1 to 10 , an outdoor frequency conversion control cabinet, comprising a cabinet 11, a hinge 18 is fixedly connected to the front end outer surface of the cabinet 11, a cabinet door 12 is hingedly connected to the cabinet 11 through the hinge 18, a protective component is arranged on the outer surface of the cabinet 11, and the protective component comprises a bracket 16 fixedly connected to the upper end outer surface of the cabinet 11, the number of the bracket 16 is two groups and they are parallelly distributed on the left and right, the bracket 16 is a U-shaped structure, and a protective plate 17 is fixedly connected to the upper end outer surface of the bracket 16;

[0043] The cabinet 11 is provided with a sealing assembly inside, and the sealing assembly includes a storage groove 31 provided inside the cabinet 11, and a capsule 32 is fixedly connected to the lower end of the inner surface of the storage groove 31, and the capsule 32 is made of a high temperature resistant elastic rubber material, and the left and right ends of the inner surface of the cabinet 11 are symmetrically fixedly connected to a fixing seat 38, and the fixing seat 38 is hollow inside;

[0044] A ventilation assembly is provided on the upper side of the inner surface of the cabinet 11, and the ventilation assembly includes a protective cover 24 fixedly connected to the upper end of the inner surface of the cabinet 11. A servo motor 22 is fixedly connected to the outer surface of the upper end of the cabinet 11. A connecting shaft 26 is fixedly connected to the lower end of the output shaft of the servo motor 22. The connecting shaft 26 penetrates into the interior of the cabinet 11 and is rotatably connected to the cabinet 11.

[0045] By adopting the above technical scheme, the cabinet body 11 and the cabinet door 12 constitute the external structure of the frequency conversion control cabinet. The protective component can provide good protection for the electrical components inside the control cabinet. When the temperature inside the control cabinet is normal, the sealing component can effectively reduce the entry of moisture into the control cabinet, thereby keeping the air humidity in the control cabinet within a low range, reducing the corrosion of the electrical components inside the control cabinet by condensation, and extending the service life of the control cabinet. The ventilation component can accelerate the air circulation inside and outside the control cabinet when the temperature inside the cabinet body 11 is too high, thereby achieving the effect of cooling the inside of the control cabinet.

[0046] like Figure 1 , Figure 2 and Figure 4 As shown, a support 13 is fixedly connected to the outer surface of the lower end of the cabinet 11, and the support 13 is a rectangular structure. A controller 15 is fixedly connected to the rear end of the inner surface of the cabinet 11, and a rain shield 19 is fixedly connected to the front side of the upper outer surface of the protective plate 17. A cover plate 14 is symmetrically fixedly connected to the lower left and right sides of the outer surface of the cabinet 11, and the outer surface of the upper end of the cover plate 14 is arc-shaped. Ventilation grilles 21 are symmetrically provided at the left and right ends of the outer surface of the cabinet 11.

[0047] By adopting the above technical solution, the control cabinet fixes the cabinet body 11 to the ground through the support 13 when in use, and the controller 15 is fixedly installed inside the cabinet body 11, so that the cabinet body 11 can maintain a certain distance from the ground, reducing the ground moisture from entering the cabinet body 11, and the cabinet door 12 is hinged to the cabinet body 11 through the hinge 18, and the cabinet body 11 fixes and supports the bracket 16, so that the protective plate 17 is fixedly supported by the bracket 16, and the protective plate 17 is inclined to block rainwater and quickly drain rainwater, thereby reducing the corrosion of rainwater to the control cabinet body 11, and the protective plate 17 The rain shield 19 on the front side can block rainwater and reduce rainwater dripping from the front side of the cabinet door 12. At the same time, the protective plate 17 can provide good protection for the servo motor 22, reduce the erosion of the servo motor 22 by rainwater, and thus improve the stability of the servo motor 22 during operation. The ventilation grilles 21 on both sides of the cabinet body 11 can facilitate the circulation of air inside and outside the cabinet body 11, thereby helping to control the ventilation and heat dissipation inside the cabinet. The cover plate 14 is located on the upper side of the ventilation grille 21, which can block rainwater on the surface of the cabinet body 11 and reduce rainwater from entering the cabinet body 11 through the ventilation grille 21.

[0048] like Figure 4 , Figure 6 , Figure 8 and Fig.10 As shown, a second storage slot 34 is embedded in the inner side of the cabinet body 11, the front end of the second storage slot 34 is connected to the inside of the first storage slot 31, the lower end of the second storage slot 34 extends to the lower side of the ventilation grille 21, and a connecting rod 33 is fixedly connected to the outer surface of the upper end of the bag body 32, and the rear end of the connecting rod 33 passes through the inner side of the second storage slot 34 and is in sliding contact with the inner surface of the second storage slot 34.

[0049] A sealing plate 35 is fixedly connected to the outer surface of the lower end of the connecting rod 33, and the sealing plate 35 is located on the inner side of the second storage groove 34 and is in sliding contact with the inner surface of the second storage groove 34. The lower end of the fixing seat 38 is fixedly connected to the lower end of the inner surface of the cabinet 11. A bottom hole 36 is opened in the middle of the outer surface of the lower end of the cabinet 11, and a filter screen 37 is fixedly connected to the inner surface of the bottom hole 36.

[0050] By adopting the above technical solution, before the control cabinet works, the sealing plate 35 is located at the lower side of the inner surface of the second storage slot 34, and the ventilation grille 21 is sealed by the sealing plate 35, so as to reduce the moisture entering the control cabinet with the air through the ventilation grille 21. After the electrical components in the cabinet 11 have been running for a period of time, the electrical components generate heat to gradually increase the temperature inside the control cabinet 11, and the heat will be transferred to the capsule 32 through the cabinet 11. The capsule 32 is sufficiently filled with carbon dioxide. As the temperature gradually increases, the carbon dioxide gas will gradually expand due to the heat. As the volume of the capsule 32 continues to increase, the capsule 32 will drive the connecting rod 33 to slide upward along the inner surfaces of the first storage slot 31 and the second storage slot 34. During the upward movement of the connecting rod 33, the sealing plate 35 will be driven to move upward. As the sealing plate 35 gradually moves upward, the sealing plate 35 will contact the ventilation grille 2 at the bottom. 1 gradually disengages from contact, thereby releasing the sealing plate 35 from the sealing of the ventilation grille 21, facilitating the circulation of air inside and outside the cabinet 11, and further contributing to the heat dissipation inside the cabinet 11. If the temperature inside the cabinet 11 continues to rise, the capsule 32 will continue to expand so that the connecting rod 33 drives the sealing plate 35 to move to the uppermost position, thereby fully opening the ventilation grille 21 to increase the circulation of air inside and outside the cabinet 11, thereby accelerating the discharge of heat inside the cabinet 11. By setting a sealing component, the ventilation grille 21 can be sealed when the temperature inside the cabinet 11 is low, reducing the amount of moisture entering the cabinet 11 with the air, thereby reducing the probability of condensation to a certain extent, thereby effectively improving the working stability of the variable frequency control cabinet, and at the same time, when the temperature inside the cabinet 11 rises, automatic ventilation and heat dissipation of the cabinet 11 can be achieved.

[0051] like Figure 1 , Figure 5 , Figure 6 and Figure 7 As shown, the ventilation grille 21 is located directly below the cover plate 14, an exhaust groove 23 is provided on the outer surface of the upper end of the cabinet body 11, a fan blade 27 is fixedly connected to the outer surface of the connecting shaft 26, and an exhaust groove 25 is provided on the outer surface of the lower end of the protective cover 24. The number of the exhaust grooves 1 23 and the exhaust grooves 2 25 are both several groups and are distributed in a ring array.

[0052] The outer surface of the upper end of the connecting rod 33 is fixedly connected to the electrode sheet 29, and the upper end of the inner surface of the storage groove 2 34 is fixedly connected to the electrode sheet 1 28. The electrode sheet 1 28 is located directly above the electrode sheet 29. The servo motor 22, the electrode sheet 1 28, and the electrode sheet 2 29 are electrically connected to the control module respectively.

[0053] By adopting the above technical solution, the sealing component will drive the ventilation component to start and run synchronously during operation. When the temperature inside the cabinet 11 rises to a certain extent, the connecting rod 33 will drive the electrode sheet 2 29 to continue to move upward. When the electrode sheet 29 moves to contact the electrode sheet 1 28, the electrode sheet 1 28 and the electrode sheet 2 29 control the servo motor 22 to start running through the control module. The output shaft of the servo motor 22 drives the fan blade 27 to rotate, thereby discharging the warm gas inside the cabinet 11 through the exhaust groove 25 and the exhaust groove 1 23 to the outside of the cabinet 11 in turn. As the warm gas is discharged from the cabinet 11, a certain negative pressure will be formed in the cabinet 11, and the air outside the cabinet 11 will enter the cabinet 11 through the ventilation grille 21, thereby accelerating the circulation of air inside and outside the cabinet 11. The air flow and contact with the electrical components can take away most of the heat inside the cabinet 11, thereby realizing rapid air cooling of the control cabinet.

[0054] like Figure 4 , Figure 5 and Figure 8 As shown, a dehumidification component is arranged on the inner side of the fixing seat 38, and the dehumidification component includes a movable rod 45 fixedly connected to the inner surface of the fixing seat 38, and the outer surface of the movable rod 45 is rotatably connected to a silica gel plate 44, and slots 41 are symmetrically provided at the left and right ends of the inner surface of the cabinet body 11, and the slots 41 are connected to the interior of the storage slot 2 34, and a slot 2 43 is provided on the outer surface of the upper end of the fixing seat 38, and the slot 2 43 is connected to the interior of the slot 1 41.

[0055] A traction rope 42 is fixedly connected to the outer surface of the connecting rod 33, and the lower end of the traction rope 42 is fixedly connected to the upper end of the silica gel plate 44. The silica gel plate 44 is located on the inner side of the fixing seat 38, and the traction rope 42 is located on the inner side of the slot 1 41 and the slot 2 43. A support plate 47 is fixedly connected between the two groups of the fixing seats 38. A bottom hole 36 is opened in the middle of the outer surface of the upper end of the support plate 47, and a filter screen 37 is fixedly connected to the inner surface of the bottom hole 36. The filter screen 37 is located directly below the controller 15. A rectangular groove 46 is opened on the outer surface of the fixing seat 38 away from the cabinet 11, and the front and rear ends of the outer surface of the silica gel plate 44 are in sliding contact with the inner surface of the rectangular groove 46.

[0056] By adopting the above technical solution, when the control cabinet is ventilated and cooled by the ventilation component, the moisture in the environment will enter the cabinet body 11 through the ventilation grille 21 along with the air, and will also cause corrosion to the metal components in the control cabinet. For this purpose, a dehumidification component is provided. When the connecting rod 33 moves upward, it will drive the traction rope 42 to move upward synchronously. The silicate gel plate 44 can flip around the movable rod under the pulling force of the traction rope 42. The fixed seat 38 supports the silicate gel plate 44 for rotation through the movable rod 1 45, so that the silicate gel plate 44 fits tightly to the ventilation grille 21. The notch 1 41 and the notch 2 43 can ensure the normal traction and stretching of the traction rope 42. The traction rope 42 has good elasticity and can always keep the silicate gel plate 44 when the connecting rod 33 moves upward. The silica gel plate 44 is fitted to the inner wall of the cabinet 11, and has dense mesh holes to ensure air circulation. When air passes through the silica gel plate 44, the silica gel plate 44 can fully absorb moisture in the air, thereby effectively reducing moisture from entering the cabinet 11. While ensuring the ventilation and heat dissipation effect of the control cabinet, it can also reduce the probability of condensation in the cabinet 11. The fixed seat 38 fixes and supports the filter 37 through the support plate 47. After the air absorbs moisture through the silica gel plate 44, the dust in the air is filtered through the filter 37, thereby reducing dust from entering the cabinet 11 to a certain extent, reducing dust from adhering to the surface of electrical components to affect the normal heat dissipation of electrical components, and thus ensuring the stability of electrical components during operation.

[0057] like Figure 4 , Figure 5 and Fig. 9 As shown, a support assembly is provided on the inner side of the fixed seat 38, and the support assembly includes a movable rod 51 fixedly connected to the inner surface of the rectangular groove 46, and a balance rod 52 is rotatably connected to the outer surface of the movable rod 51. The movable rod 51 and the balance rod 52 are in two groups and are symmetrically distributed on the left and right.

[0058] The end of the balance rod 52 away from the silica gel plate 44 is fixedly connected to a connecting seat 53, and a counterweight block 54 is hinged on the outer surface of the upper end of the connecting seat 53. The end of the balance rod 52 away from the connecting seat 53 is in sliding contact with the outer surface of the silica gel plate 44.

[0059] By adopting the above technical solution, after the temperature in the control cabinet is lowered, the volume of carbon dioxide in the capsule 32 shrinks, and at this time the connecting rod 33 will slide downward along the storage slot 1 31 and the storage slot 2 34, and when the connecting rod 33 moves downward, it will drive the upper end of the traction rope 42 to move downward synchronously, and at this time the silicate gel plate 44 will flip toward the inside of the cabinet 11 under the action of gravity, and after the silicate gel plate 44 flips toward the inside of the cabinet 11, the contact area between the silicate gel plate 44 and the gas in the cabinet 11 can be increased, so that the moisture in the cabinet 11 is continuously adsorbed by the silicate gel plate 44, so that the humidity in the cabinet 11 can be kept within a low range, and when the silicate gel plate 44 flips downward, it will press the balance bar 52 downward, and the balance bar 52 flips around the movable rod 2 51 under the pressure of the silica gel plate 44, and the balance rod 52 away from the end of the silica gel plate 44 will lift the connecting seat 53 upward, and support the counterweight block 54 through the connecting seat 53. The counterweight block 54 will knock on the filter screen 37 during the upward movement, and the knocking will cause the filter screen 37 to vibrate, thereby reducing the adhesion of impurities on the lower surface of the filter screen 37, and it can also help to maintain the permeability of the filter screen 37 and improve the smoothness of air circulation. The balance rod 52 can have a certain lifting and supporting effect on the silica gel plate 44, thereby reducing the tension of the traction rope 42 to a certain extent, and improving the stability of the silica gel plate 44 during the dehumidification process.

[0060] Instructions for use: When the frequency conversion control cabinet is in use, as the temperature inside the control cabinet gradually rises, the carbon dioxide gas inside the capsule 32 will gradually expand due to the heat, causing the volume of the capsule 32 to increase continuously. The capsule 32 drives the sealing plate 35 to move upward through the connecting rod 33, and the sealing plate 35 will be out of contact with the ventilation grille 21 to achieve the circulation of gas inside and outside the cabinet 11. After the temperature inside the cabinet 11 rises to a certain range, the output shaft of the servo motor 22 drives the fan blade 27 to rotate through the connecting shaft 26, thereby discharging the warm gas inside the cabinet 11 to the outside of the cabinet 11 for cooling and heat dissipation, and the fixed seat 38 rotates the silica gel plate 44 through the movable rod 45. Dynamic support is provided so that the silicate gel plate 44 fits tightly to the ventilation grille 21. The silicate gel plate 44 can fully absorb moisture in the air, thereby effectively reducing the amount of moisture entering the cabinet 11. The filter 37 filters dust in the air. After the temperature in the cabinet 11 drops to a certain range, the silicate gel plate 44 flips to the inside of the cabinet 11, which can increase the contact area between the silicate gel plate 44 and the gas in the cabinet 11. The silicate gel plate 44 continuously absorbs moisture in the cabinet 11, thereby maintaining the humidity in the cabinet 11 within a relatively low range and reducing the probability of condensation forming in the cabinet 11.

[0061] The above is only a preferred specific implementation of the present invention; however, 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 solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
