Description

Technical Field

[0001] The invention belongs to the technical field of electrical equipment, and in particular relates to a distribution cabinet capable of adjusting temperature and humidity. Background Art

[0002] In modern power systems, power distribution cabinets are key equipment for power distribution and control and are widely used in various fields such as industrial production, commercial buildings, data centers, and residential buildings. A large number of electrical components are usually installed inside, such as circuit breakers, contactors, relays, transformers, etc. These components generate heat during operation, causing the temperature inside the power distribution cabinet to rise. At the same time, changes in ambient humidity will also have a significant impact on the electrical components in the power distribution cabinet.

[0003] Excessively high temperatures can reduce the insulation performance of electrical components, accelerate the aging and damage of components, reduce their service life, and may even cause electrical failures, resulting in power outages, which have a serious impact on production and life. For example, in some industrial production workshops under high temperature conditions, the temperature inside the distribution cabinet often exceeds the normal range, and electrical components frequently burn out, which not only increases maintenance costs, but also seriously affects the continuity of production. The impact of humidity on distribution cabinets should not be ignored. When the humidity is too high, condensation will form on the surface of electrical components, causing short circuits, leakage and other problems, which greatly threatens the safe and stable operation of the power system. In some coastal areas or humid climates, failures of distribution cabinets caused by humidity problems are common.

DETAILED DESCRIPTION

[0029] 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.

[0030] Example: Figure 1 — Fig.12A power distribution cabinet capable of adjusting temperature and humidity is shown, comprising: The cabinet 1 has a door 39 rotatably mounted on it, an upper end cover 37 is detachably mounted on the top of the cabinet 1, and side covers 38 are symmetrically arranged on both sides of the cabinet 1, and the side covers 38 are detachably connected to the cabinet 1.

[0031] like Figure 1 , Figure 2 As shown, the side covers 38 are located on both sides of the cabinet 1, and the upper end cover 37 is located above the cabinet 1. Both the upper end cover 37 and the side cover 38 play a protective role. At the same time, ventilation holes are also provided on the upper end cover 37 and the side cover 38, which will not affect the circulation of air in the cabinet 1.

[0032] The regulating mechanism is installed on the cabinet 1, and the regulating mechanism includes a temperature regulating component and a humidity regulating component. The temperature regulating component includes a first regulating part and a second regulating part. The humidity regulating component includes two symmetrically arranged liquid outlet barrels 23, and a plurality of nozzles 24 are provided on the liquid outlet barrels 23; A power mechanism is installed on the cabinet 1 and is used to drive the first regulating part and the humidity regulating component.

[0033] The first adjustment part includes two air cylinders 13 fixedly mounted on the cabinet 1, one end of the air cylinder 13 is connected to the interior of the cabinet 1, a rotating shaft 12 is rotatably mounted inside the air cylinder 13, an impeller 1 is arranged on one end of the rotating shaft 12, one end of the rotating shaft 12 is connected to one end of a belt assembly 11, and the other end of the belt assembly 11 is connected to a power mechanism.

[0034] like Figure 3 , Figure 4 As shown, the air cylinder 13 is installed on the cabinet 1. When the belt assembly 11 drives the rotating shaft 12 to rotate, the impeller 1 installed on the rotating shaft 12 will drive the air in the air cylinder 13 to flow. The air cylinder 13 is connected to the cabinet 1, so the air in the cabinet 1 will flow, thereby extracting the hot air in the cabinet 1, and the rotating shaft 12 can rotate forward and reverse, so that the air in the cabinet 1 can circulate. It should be noted that a vent is provided on the upper end cover 37 located on the cabinet 1, which will not block the air from flowing through the air cylinder 13. When the rotating shaft 12 and the impeller 1 are started to adjust the temperature, the humidity will be adjusted at the same time. When the humidity is reduced, it is easy to cause a fire due to high temperature, so it is adjusted at the same time.

[0035] The second adjustment part includes two symmetrically arranged baffles 27, which are rotatably mounted on the cabinet 1 via a rotating shaft. A plurality of ventilation holes 41 are provided on the cabinet 1 corresponding to the baffles 27. A coil spring is provided at the connection between the rotating shaft and the cabinet 1, and one end of the rotating shaft is drivingly connected to the output shaft of motor 1.

[0036] like Figure 1, Figure 2 , Figure 3 , Figure 5 As shown, when the temperature needs to be adjusted separately, the motor 1 fixedly mounted on the cabinet 1 can be started, and the rotating shaft can be driven by the motor 1 to rotate, so that the baffle 27 changes from a state of being close to the air hole 41 to a state of being away from the air hole 41. In this process, the coil spring will generate elastic force, and the function of the coil spring is to assist the resetting of the baffle 27. After the baffle 27 leaves the air hole 41, the air on both sides of the cabinet 1 is circulated, thereby achieving temperature adjustment.

[0037] The humidity regulating assembly also includes a piston rod 22, which is slidably mounted on the liquid outlet barrel 23. A piston plate is connected to one end of the piston rod 22 located inside the liquid outlet barrel 23, and the other end of the piston rod 22 is connected to a power mechanism. One end of a connecting pipe 25 is connected to the liquid outlet barrel 23, and both connecting pipes 25 are connected to a liquid storage barrel 26, which is fixedly mounted on the cabinet 1.

[0038] like Figure 2 , Figure 3 , Figure 5 —— Figure 7 As shown, when the surroundings of the cabinet 1 become dry and the humidity needs to be adjusted, the power mechanism drives the piston rod 22 to move back and forth along the liquid outlet barrel 23, so that the piston plate in the liquid outlet barrel 23 intermittently presses the liquid in the liquid outlet barrel 23 through the nozzle 24, thereby changing the surrounding humidity through the liquid. The liquid in the liquid outlet barrel 23 includes water, and may also include disinfectant or insecticide if necessary.

[0039] The humidity regulating assembly also includes a movable plate 32, which is slidably mounted inside the liquid storage barrel 26. Two guide rods 31 are arranged below the liquid storage barrel 26. The guide rods 31 are slidably mounted on the liquid storage barrel 26. A contact switch 33 is arranged below the guide rods 31. The contact switch 33 is fixedly mounted on the cabinet 1. A filter 36 is arranged on the movable plate 32, and the thickness of the side of the movable plate 32 close to the filter 36 is less than the thickness of the side away from the filter 36.

[0040] like Figure 8 —— Fig.10As shown, during the sliding of the piston plate, the liquid in the liquid storage barrel 26 can enter the liquid outlet barrel 23 through the connecting pipe 25, and then be discharged through the nozzle 24. During the reduction of the liquid in the liquid storage barrel 26, the movable plate 32 will drive the guide rod 2 31 to slide down along the liquid storage barrel 26 due to the reduction of buoyancy. When the guide rod 2 31 contacts the contact switch 33, an alarm will be sounded to remind the staff to add water to the liquid storage barrel 26. In addition, the top of the liquid storage barrel 26 is open, and rainwater can enter the liquid storage barrel 26, and then flow into the bottom of the movable plate 32 through the position of the filter 36, and be stored in the liquid storage barrel 26. The reason why the movable plate 32 is set to be high on one side and low on the other side is also to facilitate the rainwater to flow to the filter 36 on the movable plate 32, and the garbage such as the infusion can be filtered out through the filter 36.

[0041] The humidity regulating assembly also includes two symmetrically arranged lower liquid barrels 34 and two symmetrically arranged rotating shafts 29. The lower liquid barrels 34 are located above the movable plate 32. A latch 35 is slidably installed above the lower liquid barrels 34. A solenoid valve is provided at the through hole below. The interior of the lower liquid barrels 34 is used to load disinfectant. The rotating shaft 29 is located below the movable plate 32. The rotating shaft 29 is rotatably installed on the liquid storage barrel 26. An impeller 2 30 is fixedly installed at one end of the rotating shaft 29, and the other end of the rotating shaft 29 is connected to the power mechanism.

[0042] like Fig. 9 As shown, the two lower liquid barrels 34 can be filled with herbicides, pesticides, disinfectants, etc. When it is needed, the solenoid valve can be opened. The plug 35 is used to add herbicides, etc. into the lower liquid barrels 34. The weeds or insects around the cabinet 1 can be treated with herbicides, disinfectants, etc. to avoid affecting the circuits of other components in the cabinet 1.

[0043] The power mechanism includes two symmetrically arranged gear fours 9, which are coaxially rotatably mounted on the cabinet body 1 with the gear five 10 and the turntable 14, and the gear four 9 is connected to the end of the belt assembly 11 away from the rotating shaft 12, the gear five 10 is meshed with the gear three 8, the gear three 8 is rotatably mounted on the cabinet body 1, and the gear three 8 is coaxially fixedly connected with the gear two 7.

[0044] like Figure 2 , Figure 3 , Figure 4 , Fig.12 As shown, when gear three 8 drives gear five 10 to rotate, coaxially connected gear four 9, gear five 10 and turntable 14 will rotate, so that the belt assembly 11 connected to gear four 9 will drive shaft one 12 to rotate, thereby driving impeller one to rotate through shaft one 12 to adjust the temperature.

[0045] The power mechanism also includes two symmetrically arranged rocker arms 15, one end of which is mounted on the turntable 14, and the other end of which is rotatably mounted on a slider 16, which is slidably mounted on the cabinet 1, and one end of a driving rod 17 is connected to the slider 16, and the other end of the driving rod 17 is connected to one end of a long rod 21, and the other end of the long rod 21 is connected to one end of a telescopic rod 28, and the other end of the telescopic rod 28 is connected to a rotating shaft 29, and a piston rod 22 is connected to the long rod 21, and a slider 2 18 is provided at the connection between the long rod 21 and the driving rod 17, and the slider 2 18 is slidably matched with a guide rod 19 fixedly mounted on the cabinet 1, and a reset spring 20 is provided between the slider 2 18 and the cabinet 1.

[0046] like Figure 6 , Figure 7 , Fig.12 As shown, when the turntable 14 performs circular motion, the turntable 14 drives the slider 16 to slide back and forth along the cabinet 1 through the swing rod 15, and the slider 16 drives the long rod 21 to swing through the driving rod 17. In this process, the slider 2 18 slides along the guide rod 19, and the function of the reset spring 20 is to assist the reset of the slider 2 18; during the swinging process of the long rod 21, on the one hand, the long rod 21 drives the piston rod 22 to move up and down reciprocatingly, and on the other hand, the long rod 21 drives the rotating shaft 29 to rotate through the telescopic rod 28, so that the impeller 2 30 on the rotating shaft 29 stirs the liquid in the liquid storage barrel 26, and the purpose of doing so is to make the water in the liquid storage barrel 26 and the disinfectant etc. be evenly mixed. The two sides of the telescopic rod 28 are retractable, so they will not interfere with the rotation of the rotating shaft 29 and the swinging of the long rod 21.

[0047] The power mechanism also includes two guide plates 6 symmetrically installed on the cabinet 1, and racks 4 are slidably installed on the guide plates 6. The two symmetrically arranged racks 4 are respectively meshed with two gears 5. The two gears 5 are rotatably installed on the sliding rod 40. One end of the rotating rod 3 is connected to the sliding rod 40, and the other end of the rotating rod 3 is rotatably connected to the output shaft of the motor 2 2 fixedly installed on the cabinet 1.

[0048] like Fig.11 , Fig.12As shown, start motor 2 2, and drive the rotating rod 3 to rotate through the output shaft of motor 2 2, so that the rotating rod 3 pushes the sliding rod 40 to move back and forth in a straight line, and the gears 1 5 on both sides of the sliding rod 40 slide along the guide plate 6. When gear 1 5 is engaged with gear 2 7, since gear 1 5 moves along the rack 4, gear 1 5 will rotate, and then gear 2 7 will rotate, so that gear 2 7 moves with gear 3 8, so that gear 5 10 rotates. At this time, the rotation direction of gear 5 10 is direction one. When gear 1 5 moves to direct contact with gear 4 9, gear 1 5 drives gear 5 10 to rotate through gear 4 9. At this time, the rotation direction of gear 4 9 is direction two, and direction one is opposite to direction two. In this way, the rotating shaft 12 can be rotated in different directions.
