Description

Technical Field

[0001] This invention relates to the field of control cabinet technology, specifically to an integrated control cabinet. Background Technology

[0002] An industrial park is an area designated by a national or regional government through administrative means based on its own economic development requirements. It gathers various production factors, scientifically integrates them within a certain spatial range, improves the intensity of industrialization, highlights industrial characteristics, optimizes functional layout, and makes it a modern industrial division of labor and collaborative production area that adapts to market competition and industrial upgrading. Industrial parks often have integrated control cabinets installed outdoors.

[0003] A control cabinet is a set of switchgear, measuring instruments, protective devices, and auxiliary equipment assembled in a closed or semi-closed metal cabinet or panel according to electrical wiring requirements. Its layout should meet the requirements of normal operation of the power system, facilitate maintenance, and not endanger the safety of personnel and surrounding equipment. During normal operation, the circuit can be connected or disconnected by manual or automatic switches. In case of fault or abnormal operation, the circuit can be cut off or an alarm can be triggered by protective devices. Various parameters during operation can be displayed by measuring instruments, and some electrical parameters can be adjusted. The control cabinet can also provide prompts or signals for deviations from normal operating conditions.

[0004] In existing technologies, most control cabinets are cooled by cooling fans. However, most of these fans are installed in a fixed manner, which results in a fixed airflow trajectory inside the control cabinet. Consequently, the overall circulating airflow trajectory within the control cabinet is relatively simple, leading to poor overall cooling performance. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide an integrated control cabinet to solve the technical problem that most of the existing cooling fans are installed in a fixed manner, which results in the cooling airflow trajectory generated by the cooling fan inside the control cabinet remaining unchanged, thus making the overall circulating cooling airflow trajectory inside the control cabinet relatively simple and the overall cooling effect poor.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a comprehensive control cabinet, including a cabinet body and a rear exhaust plate fixedly installed at one end and a cabinet door installed at the other end. Air intake grilles are provided on both sides of the cabinet body. Fixed guide rails located on both sides of the rear exhaust plate are fixedly installed at one end of the cabinet body, and a lifting sliding frame is slidably connected between the two sets of fixed guide rails.

[0007] Multiple sets of cooling fans are evenly fixed inside the lifting sliding frame. Each set of cooling fans has an output shaft fixed at one end. A worm gear is fixed to the outside of the output shaft. A worm is meshed at the bottom of the multiple sets of worm gears. Connecting frames are fixed on both sides of the lifting sliding frame. A transmission shaft that is fixedly connected to the worm is rotatably connected inside the two sets of connecting frames. A rack is fixed to both sides at one end of the cabinet. A climbing gear that meshes with the rack is axially slidably connected to the outside of the two sets of transmission shafts. Specifically, the climbing gear and the transmission shaft are axially slidably connected through a limiting slip ring. The limiting slip ring and the climbing gear are fixedly connected. A slider extending into the transmission shaft is fixedly installed inside the limiting slip ring. A groove that cooperates with the slider is opened inside the transmission shaft.

[0008] A spring frame is fixedly installed between the connecting frame and the climbing gear. A first baffle located outside the rack is fixed at one end of the cabinet. A second baffle located outside the first baffle is fixed at one end of the cabinet. Guide inclined plates are fixedly installed at the bottom of both sets of second baffles. Specifically, the horizontal height of the top and bottom of the first baffle is lower than the horizontal height of the rack, and the distance between the first baffle and the second baffle is the same as the width of the climbing gear.

[0009] By adopting the above technical solution, a height-adjustable sliding frame is installed on the outside of the rear exhaust plate, and multiple sets of cooling fans are installed inside the sliding frame to dissipate heat from the inside of the cabinet. Specifically, when the cooling fans rotate, they drive the worm gear to rotate, which in turn meshes with the worm to make it rotate. Since there are drive shafts fixed on both sides of the worm, the drive shafts drive the climbing gear to mesh with the rack and pinion to perform a climbing action. When the sliding frame rises to the top, the climbing gear disengages from the limit of the first baffle, and under the action of the spring frame, the climbing gear moves axially along the drive shaft. Then, the climbing gear disengages from the gear plate, and under the gravity of the lifting sliding frame, the lifting sliding frame drives multiple cooling fans to move from top to bottom. When the lifting sliding frame moves to the bottom, the climbing gear, under the action of the guide plate at the bottom of the second baffle, gradually meshes with the bottom tooth groove of the rack. After meshing, the climbing gear can continue to climb under the action of the rack. Repeating the above steps, the cooling fans can continuously and repeatedly dissipate heat at any height inside the cabinet, thereby diversifying the heat dissipation airflow trajectory and improving the heat dissipation effect of the cabinet.

[0010] The present invention is further configured such that a roller mechanism is fixedly installed at the top and bottom of one end of the cabinet, and the two sets of roller mechanisms and the lifting sliding frame are fixedly connected by a shielding cloth. A torsion spring is installed inside the roller mechanism, and the two ends of the torsion spring are fixedly connected to the roller mechanism and the roller inside the roller mechanism, respectively.

[0011] By adopting the above technical solution, a roller mechanism is fixedly installed at both the top and bottom of the cabinet. The roller mechanism contains a torsion spring and a shielding cloth fixedly connected to the lifting sliding frame. When the lifting sliding frame rises, the shielding cloth at the top is rolled up under the action of its corresponding torsion spring, while the shielding cloth at the bottom is released as the lifting sliding frame rises. Thus, the two sets of shielding cloths can cover the rest of the back exhaust plate, preventing external impurities from entering the interior of the cabinet through the back exhaust plate, effectively improving the safety of the cabinet.

[0012] The present invention is further configured such that protective plates located outside the climbing gear and rack are fixedly installed on both sides of one end of the cabinet.

[0013] By adopting the above technical solution, the protective plate plays a role in protecting the climbing gear and rack, preventing external impurities from affecting the climbing gear and rack.

[0014] In summary, the present invention has the following main beneficial effects:

[0015] 1. This invention features a height-adjustable sliding frame on the outer side of the rear exhaust plate, with multiple cooling fans inside the frame to dissipate heat from the cabinet interior. Specifically, the rotating cooling fans drive a worm gear to rotate, which in turn meshes with a worm to rotate. Since drive shafts are fixed on both sides of the worm, these drive shafts drive a climbing gear to mesh with a rack for climbing action. When the sliding frame reaches its highest point, the climbing gear disengages from the first baffle and, under the action of a spring frame, moves axially along the drive shaft, thus climbing... The lifting gear disengages from the toothed plate, allowing the lifting sliding frame to move multiple cooling fans from top to bottom under the weight of the lifting sliding frame. When the lifting sliding frame reaches the bottom, the climbing gear, guided by the inclined plate at the bottom of the second baffle, gradually engages with the bottom tooth groove of the rack. The engaged climbing gear can then continue to climb under the action of the rack. By repeating the above steps, the cooling fans can continuously and repeatedly cool the interior of the cabinet at any height, thus diversifying the airflow trajectory and improving the cooling effect of the cabinet.

[0016] 2. This invention features a roller mechanism fixedly installed at both the top and bottom of the cabinet. The roller mechanism contains a torsion spring and a shielding cloth fixedly connected to the lifting sliding frame. When the lifting sliding frame rises, the shielding cloth at the top is rolled up under the action of its corresponding torsion spring, while the shielding cloth at the bottom is released as the lifting sliding frame rises. Thus, the two sets of shielding cloths can cover the rest of the back exhaust plate, preventing external impurities from entering the cabinet through the back exhaust plate and effectively improving the safety of the cabinet.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0027] The embodiments of the present invention will now be described.

[0028] A type of integrated control cabinet, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, it includes a cabinet 1, a back exhaust plate 2 fixed at one end, and a cabinet door 25 at the other end. Air intake grilles 24 are provided on both sides of the cabinet 1 to facilitate the entry of outside air into the cabinet 1. Fixed guide rails 3 are fixed at one end of the cabinet 1 on both sides of the back exhaust plate 2. A lifting sliding frame 4 is slidably connected between the two sets of fixed guide rails 3. The back exhaust plate 2 facilitates the discharge of hot air from the inside of the cabinet 1.

[0029] Multiple cooling fans 5 are evenly fixed inside the lifting sliding frame 4. Each cooling fan 5 has an output shaft 6 fixed at one end. Worm gears 7 are fixed to the outside of the output shafts 6, and worm gears 9 are meshed at the bottom of the worm gears 7. Connecting frames 8 are fixed on both sides of the lifting sliding frame 4. Drive shafts 10, which are fixedly connected to the worm gears 9, are rotatably connected inside the two connecting frames 8. Racks 11 are fixed to both sides at one end of the cabinet 1. Climbing gears 14, which mesh with the racks 11, are axially slidably connected to the outside of the two drive shafts 10. Specifically, the climbing gears 14 and the drive shafts 10 are axially slidably connected via limiting slip rings 16, and the limiting slip rings 16 and the climbing gears 14 are fixedly connected. The 16 is internally fixed with a slider 17 extending into the drive shaft 10. The drive shaft 10 has a groove 18 that cooperates with the slider 17. A lifting and sliding frame 4 is provided on the outside of the exhaust plate 2 at the back. The lifting and sliding frame 4 is equipped with multiple sets of cooling fans 5 to reciprocate and lift the cabinet 1 to dissipate heat. The cooling fans 5 draw in air from the cabinet 1, allowing outside air to enter the cabinet 1 through two sets of air intake grilles 24. The air is then discharged outside the cabinet 1 through the cooling fans 5 and the ventilated shell 20. This allows the cooling fans 5 to continuously and reciprocate to dissipate heat at any height inside the cabinet 1, thereby diversifying the heat dissipation airflow trajectory and improving the heat dissipation effect of the cabinet 1.

[0030] A spring frame 15 is fixedly installed between the connecting frame 8 and the climbing gear 14. A first baffle 12 located outside the rack 11 is fixed at one end of the cabinet 1, and a second baffle 13 located outside the first baffle 12 is fixed at one end of the cabinet 1. Guide inclined plates 19 are fixedly installed at the bottom of both sets of second baffles 13. Specifically, the horizontal height of the top and bottom of the first baffle 12 is lower than the horizontal height of the rack 11, and the distance between the first baffle 12 and the second baffle 13 is the same as the width of the climbing gear 14.

[0031] Please see Figure 1The top and bottom of one end of the cabinet 1 are both fixedly equipped with a roller mechanism 21. The two roller mechanisms 21 and the lifting sliding frame 4 are fixedly connected by a shielding cloth 22. The roller mechanism 21 is equipped with a torsion spring, and the two ends of the torsion spring are fixedly connected to the roller mechanism and the roller inside the roller mechanism, respectively. With the above structure, when the lifting sliding frame 4 rises, the shielding cloth 22 at the top is rolled up under the action of its corresponding torsion spring, while the shielding cloth 22 at the bottom is released as the lifting sliding frame 4 rises. Thus, the two shielding cloths 22 can shield the rest of the back exhaust plate 2, preventing external impurities from entering the interior of the cabinet 1 through the back exhaust plate 2, effectively improving the safety of the cabinet.

[0032] Please see Figure 1 Both sides of one end of the cabinet 1 are fixedly provided with protective plates 23 located outside the climbing gear 14 and rack 11. By setting the above structure, the protective plates 23 play a protective role for the climbing gear 14 and rack 11.

[0033] The working principle of this invention is as follows: When in use, the power is turned on. This invention has a lifting and sliding frame 4 that can be raised and lowered on the outside of the exhaust plate 2 on the back. The lifting and sliding frame 4 is equipped with multiple sets of cooling fans 5 to reciprocate the lifting and lowering of the cabinet 1 to dissipate heat. The cooling fans 5 draw air into the cabinet 1, allowing outside air to enter the cabinet 1 through two sets of air intake grilles 24, and then discharge the air out of the cabinet 1 through the cooling fans 5 and the ventilated shell 20.

[0034] Specifically, when the cooling fan 5 rotates, it drives the worm gear 7 to rotate, and then the worm gear 7 meshes with the worm 9 to rotate. Since the drive shaft 10 is fixed on both sides of the worm 9, the drive shaft 10 drives the climbing gear 14 to mesh with the rack 11 to perform a climbing action.

[0035] When the lifting sliding frame 4 rises to the top, since the top height of the first baffle 12 is below the rack 11, the climbing gear 14 disengages from the limit of the first baffle 12. During the climbing process, the spring frame 15 is in a compressed state. At this time, under the action of the spring frame 15, the climbing gear 14 moves axially along the transmission shaft 10, and then the climbing gear 14 disengages from the rack 11. Thus, under the action of the gravity of the lifting sliding frame 4, the lifting sliding frame 4 drives multiple cooling fans 5 to move from top to bottom.

[0036] Furthermore, after the spring frame 15 releases a portion of the compressive force to disengage the climbing gear 14 from the first baffle 12, the spring frame 15 remains in a compressed state. At this time, the side of the climbing gear 14 is tightly fitted with the second baffle 13, and there is a certain friction between them. During the descent, under the action of the torsion spring inside the top roller mechanism, the sum of the weights of the lifting sliding frame 4 and the multiple cooling fans 5 is greater than the sum of the friction and the force between the torsion springs, thereby enabling the lifting sliding frame 4 to drive the multiple cooling fans 5 to descend slowly and uniformly.

[0037] Furthermore, when the lifting sliding frame 4 moves to the bottom, the climbing gear 14, under the action of the guide inclined plate 19 at the bottom of the second baffle 13, gradually meshes with the bottom tooth groove of the rack 11. Thus, the climbing gear 14, after meshing, can continue to climb under the action of the rack 11. Repeating the above steps, the cooling fan 5 can continuously and repeatedly dissipate heat at any height inside the cabinet 1, thereby diversifying the heat dissipation airflow trajectory and improving the heat dissipation effect of the cabinet 1.

[0038] Furthermore, under the action of gravity between the lifting sliding frame 4 and multiple cooling fans 5, the climbing gear 14 can compress the spring frame 15 under the action of the guide plate 19, thereby causing the climbing gear 14 to mesh with the rack 11 again. With the continuous transmission of the worm gear 7 and the worm 9, the meshed climbing gear 14 can continue to climb along the rack 11.

[0039] Due to the high-speed rotation of the cooling fan 5, the output speed is reduced by the cooperation of the worm gear 7 and the worm 9. In other words, the meshing between the worm gear 7 and the worm 9 is equivalent to a reducer structure, which enables the drive shaft 10 to drive the climbing gear 14 to rotate evenly and slowly, ensuring the effective heat dissipation of the cooling fan 5 at any height of the cabinet 1.

[0040] By fixing a roller mechanism 21 at both the top and bottom of the cabinet 1, and by installing a torsion spring and a cover cloth 22 fixedly connected to the lifting sliding frame 4 inside the roller mechanism 21, when the lifting sliding frame 4 rises, the cover cloth 22 at the top is rolled up under the action of its corresponding torsion spring.

[0041] The bottom cover 22 is released as the lifting sliding frame 4 rises, so that the two sets of cover 22 can cover the rest of the back exhaust plate 2, preventing external impurities from entering the cabinet 1 through the back exhaust plate 2, effectively improving the safety of the cabinet.
