Description

Technical Field

[0001] The present invention relates to the technical field of distribution cabinets, and specifically relates to an outdoor distribution cabinet with adjustable insulation performance. Background Art

[0002] A distribution cabinet is a general term for a motor control center. Distribution cabinets are divided into power distribution cabinets, lighting distribution cabinets, metering cabinets, etc. They are the end - level equipment of the power distribution system. Distribution cabinets are applicable to occasions where the load is relatively scattered and the number of circuits is small, while motor control centers are used in occasions where the load is concentrated and the number of circuits is large. They distribute the electric energy of a certain circuit of the upper - level power distribution equipment to nearby loads and provide protection, monitoring, and control for the loads.

[0003] When an outdoor distribution cabinet works in an outdoor environment, it is often affected by the external environment. When the external environment has a high humidity, when the moist air enters the outdoor distribution cabinet for heat dissipation, water molecules may adhere to the electronic components, which may cause damage to the electronic components, thus affecting the normal operation of the outdoor distribution cabinet. Summary of the Invention

[0004] The purpose of the present invention is to provide an outdoor distribution cabinet with adjustable insulation performance to solve the problems raised in the above - mentioned background art.

[0005] To solve the above - mentioned technical problems, the present invention provides the following technical solutions:

[0006] An outdoor distribution cabinet with adjustable insulation performance includes a housing. A plurality of equipment doors are arranged on the side wall of the housing. An integrated cabinet is arranged on one side of each equipment door close to the housing. The equipment door is rotatably connected to the housing. An adjusting device is arranged inside the housing. The adjusting device includes an adjusting block and an adjusting cavity. The adjusting block is arranged on the top of the housing, and the adjusting cavity is arranged inside the housing.

[0007] When the staff needs to repair the integrated cabinet, they can open the equipment door to repair the integrated cabinet. When the distribution cabinet is working, the controller controls the adjusting device to start. If the external air is in a dry state, the external air is directly input into the housing, and then the external air directly conducts heat dissipation treatment on the integrated cabinet. If the humidity in the external air is high, the humidity of the external air is adjusted through the cooperation of the adjusting block and the adjusting cavity, and the water contained in the external air is dehydrated, so that the external air reaches a dry state, and then heat dissipation treatment is carried out, thus realizing the adjustable insulation performance of the integrated cabinet, avoiding damage to the electronic components in the integrated cabinet caused by the external air with high humidity during heat dissipation, and further affecting the normal operation of the integrated cabinet.

[0008] Preferably, a plurality of air inlets are provided on the side wall of the adjusting block, and the plurality of air inlets are arranged around the axis of the adjusting block. The adjusting cavity is composed of an inner cavity and an outer cavity, and both the inner cavity and the outer cavity are communicated with the air inlets. A hygrometer is provided outside the adjusting block.

[0009] Preferably, a fixing column is provided between the inner cavity and the outer cavity. A plurality of rotating plates are provided at the top of the fixing column, and the plurality of rotating plates are arranged around the axis of the fixing column. A micro motor is provided at the top of the fixing column, and the driving shaft of the micro motor is connected to the rotating plate.

[0010] Preferably, the rotating plates correspond to the air inlets one by one. A sealing strip is provided on the side of the rotating plate, and the rotating plate is in sealed sliding connection with the air inlet. The cross section of the space surrounded by the plurality of rotating plates is octagonal.

[0011] Preferably, the outer cavity is communicated with the integrated cabinet. A plurality of air outlets are provided on the fixing column, and the air outlets are arranged around the axis of the fixing column. Both ends of the air outlet are communicated with the inner cavity and the outer cavity respectively. A waterproof breathable film is provided at one end of the air outlet close to the inner cavity.

[0012] Preferably, a rotating shaft is provided inside the adjusting block. A rotating fan is provided on one side of the rotating shaft close to the inner cavity. A driving motor is provided at the top of the adjusting block, and the driving shaft of the driving motor is connected to the rotating shaft. A rotating column is provided in the inner cavity, a spiral fin is provided on the rotating column, a refrigerator is provided in the rotating column, the rotating column is connected to the rotating fan through a bracket, and the rotating column is rotationally connected to the inner cavity.

[0013] Preferably, a water drainage groove is provided at the bottom of the inner cavity. One end of the water drainage groove away from the inner cavity is provided with a pressure cavity. A piston column is slidably connected in the pressure cavity. One end of the piston column away from the pressure cavity is provided with a crank wheel. An electric cylinder is provided in the crank wheel, and the push rod of the electric cylinder is connected to the bottom of the rotating column. The crank wheel is below the ground plane.

[0014] Preferably, the rotating fan is provided with outer blades and inner blades. The arrangement directions of the outer blades and the inner blades are the same, and the number of the outer blades is greater than the number of the inner blades.

[0015] Preferably, a frame is provided between two adjacent equipment doors. A plurality of conveying ports are provided on the frame. The conveying ports are communicated with the outer cavity through pipelines. A water conveying channel is also provided on the conveying ports, and the water conveying channel is communicated with the pressure cavity. Both the conveying ports and the air outlets are one-way pipes.

[0016] When the outside air is in a dry state, the axes of several rotating plates are parallel to the axis of the inner cavity at this time, thus disconnecting the inner cavity from the air inlet. At this time, the outer cavity is in communication with the air inlet. Then, the outside air is input into the adjusting block through the air inlet, and then conveyed to the outer cavity through the air inlet, so that the outside air directly contacts the integrated cabinet, thus achieving the heat dissipation effect. The output outside air is output to the delivery port through the pipeline, so that the outside air is discharged from the housing, realizing the heat dissipation cycle;

[0017] When the outside air has a high humidity, the hygrometer outside the adjusting block converts the humidity signal into an electrical signal and transmits the electrical signal to the air controller. Then the controller controls the micro motor at the top of the fixed column to start. The drive shaft of the micro motor then drives the rotating plate to rotate. During the rotation of the rotating plate, the rotating plate rotates towards the side away from the rotating fan. Then the rotating plate rotates into the air inlet. Since a sealing strip is provided on the side of the rotating plate, when the axis of the rotating plate is perpendicular to the axis of the inner cavity, at this time, the plane of the side of the rotating plate close to the inner cavity is on the same plane as the lower plane of the air inlet. Thus, the rotating plate disconnects the outer cavity from the air inlet, while the inner cavity is in communication with the air inlet;

[0018] Subsequently, the controller controls the drive motor to start. The drive shaft of the drive motor drives the rotating shaft to rotate. When the rotating shaft rotates, it drives the rotating fan to rotate. Since there are outer blades and inner blades, and the number of outer blades is greater than the number of inner blades, the rotating fan drives the outside air containing moisture to be conveyed into the interior of the adjusting block through the air inlet. The outer blades with a larger number quickly extract the outside air into the interior of the adjusting block. The outside air flows from the outer blades to the inner blades, and the inner blades convey the outside air to the inner cavity;

[0019] While the rotating fan is rotating, the rotating fan drives the rotating column to rotate through the bracket. During the rotation of the rotating column, the spiral blade is driven to rotate. At the same time, the controller controls the cooler to start. The low temperature generated by the cooler is transmitted to the rotating column and the spiral blade. And when the outside air is conveyed into the inner cavity, the rotational force generated by the spiral blade and the rotating column drives the outside air to move in a spiral motion in the inner cavity. During the movement of the outside air, it contacts the spiral blade and the rotating column. Under the influence of the low temperature, the moisture in the outside air condenses on the surfaces of the spiral blade and the rotating column. And under the action of the rotational force, the water droplets will be thrown towards the inner wall of the inner cavity under the action of centrifugal force. The remaining gas is conveyed to the outer cavity through the air outlet, and then the outer cavity is used to dissipate heat from the integrated cabinet. And the condensed water droplets flow along the axis of the inner cavity to the water trough and are finally stored in the water trough;

[0020] When the external temperature rises, the controller controls the electric cylinder inside the crank to start. The push rod of the electric cylinder moves towards the rotating column. Subsequently, the push rod is connected to the rotating column. When the rotating column rotates, it drives the crank to rotate. When the crank rotates, it drives the piston column to reciprocate along the axis of the pressure chamber. At this time, the controller controls the opening of the connection between the water delivery tank and the pressure chamber. The water in the water delivery tank is then delivered into the pressure chamber. After the water is delivered into the pressure chamber, the piston column pushes the water in the pressure chamber to be compressed, compressing the water in the pressure chamber into small liquid droplets. Subsequently, the small liquid droplets are delivered to the delivery port through the water delivery channel and finally sprayed outwards through the delivery port. After the small liquid droplets are sprayed out from the delivery port, they are evaporated under the action of high temperature, thereby reducing the temperature around the power distribution cabinet, effectively alleviating the problem of the working temperature of the power distribution cabinet rising under high temperature conditions, improving the heat dissipation efficiency of the power distribution cabinet, and ensuring the stable operation of the power distribution cabinet.

[0021] Compared with the prior art, the beneficial effects achieved by the present invention are as follows:

[0022] By changing the rotation position of the rotating plate, the air inlet is respectively communicated with the outer cavity and the inner cavity. Thus, when the external environment is dry, the external air is input into the outer cavity to directly dissipate heat from the power distribution cabinet. When the external environment is relatively humid, after separating the moisture through condensation, the power distribution cabinet is cooled, and the condensed water is stored. When the external environment temperature is relatively high, through the action of the crank and the piston rod, the condensed water is sprayed from the power distribution cabinet to the outside for evaporation, thereby reducing the external environment temperature.

[0042] The working principle of the present invention:

[0043] When the staff needs to overhaul the integrated cabinet, the equipment door 11 is opened, and the integrated cabinet can be overhauled. When the power distribution cabinet is working, the controller controls the adjusting device 2 to start;

[0044] When the outside air is in a dry state, the axes of several rotating plates 27 are parallel to the axis of the inner cavity 24 at this time, so that the inner cavity 24 is separated from the air inlet 23. At this time, the outer cavity 25 is in communication with the air inlet 23. Then, the outside air is input into the adjusting block 21 through the air inlet 23, and then conveyed to the outer cavity 25 through the air inlet 23, so that the outside air directly contacts the integrated cabinet, thus achieving the heat dissipation effect. The output outside air is output to the delivery port 12 through the pipeline, so that the outside air is discharged from the housing 1, realizing the heat dissipation cycle;

[0045] When the outside air has a high humidity, the hygrometer outside the adjusting block 21 converts the humidity signal into an electrical signal and transmits the electrical signal to the air controller. Then the controller controls the micro motor at the top of the fixed column 26 to start. The drive shaft of the micro motor then drives the rotating plate 27 to rotate. During the rotation of the rotating plate 27, the rotating plate 27 rotates to the side away from the rotating fan 29, and then the rotating plate 27 rotates into the air inlet 23. Since a sealing strip is provided on the side of the rotating plate 27, when the axis of the rotating plate 27 is perpendicular to the axis of the inner cavity 24, at this time, the plane of the side of the rotating plate 27 close to the inner cavity 24 is in the same plane as the lower plane of the air inlet 23. Then the rotating plate 27 separates the outer cavity 25 and the air inlet 23, while the inner cavity 24 is in communication with the air inlet 23;

[0046] Subsequently, the controller controls the drive motor to start. The drive shaft of the drive motor drives the rotating shaft 28 to rotate. When the rotating shaft 28 rotates, it drives the rotating fan 29 to rotate. Since there are outer blades 291 and inner blades 292, and the number of outer blades 291 is greater than the number of inner blades 292, the rotating fan 29 drives the outside air containing moisture to be conveyed into the adjusting block 21 through the air inlet 23. The outer blades 291 with a larger number quickly extract the outside air into the adjusting block 21. The outside air flows from the outer blades 291 to the inner blades 292, and the inner blades 292 convey the outside air to the inner cavity 24;

[0047] While the rotating fan 29 rotates, the rotating fan 29 drives the rotating column 241 to rotate through the bracket. During the rotation of the rotating column 241, the rotating column 241 drives the spiral blade 30 to rotate. At the same time, the controller controls the cooler to start, and the low temperature generated by the cooler is transmitted to the rotating column 241 and the spiral blade 30. When the outside air is conveyed into the inner cavity 24, the rotating force generated by the spiral blade 30 and the rotating column 241 drives the outside air to move in a spiral motion in the inner cavity 24. During the movement of the outside air, it contacts the spiral blade 30 and the rotating column 241. Under the influence of the low temperature, the moisture in the outside air is immediately condensed on the surfaces of the spiral blade 30 and the rotating column 241. And under the action of the rotating force, the water droplets will be thrown to the inner wall of the inner cavity 24 under the action of centrifugal force, and the remaining gas is conveyed to the outer cavity 25 through the air outlet 261, and then the outer cavity 25 is used to dissipate heat from the integrated cabinet. And the condensed water droplets flow along the axis of the inner cavity 24 to the water trough 31 and are finally stored in the water trough 31;

[0048] When the outside air temperature rises, the controller controls the electric cylinder in the crank wheel 34 to start. The push rod of the electric cylinder moves towards the rotating column 241. Subsequently, the push rod is connected to the rotating column 241. When the rotating column 241 rotates, it drives the crank wheel 34 to rotate. When the crank wheel 34 rotates, it drives the piston column 33 to reciprocate along the axis of the pressure chamber 32. At this time, the controller controls the connection between the water trough 31 and the pressure chamber 32 to open, and the water in the water trough 31 is immediately conveyed into the pressure chamber 32. When the water is conveyed into the pressure chamber 32, the piston column 33 pushes the water in the pressure chamber 32 to be compressed, compressing the water in the pressure chamber 32 into liquid water droplets. Subsequently, the liquid water droplets are conveyed to the delivery port 12 through the water delivery channel and are finally sprayed out through the delivery port 12. After the liquid water droplets are sprayed out from the delivery port 12, the liquid water droplets are evaporated under the action of the high temperature, thereby reducing the temperature around the power distribution cabinet, and effectively alleviating the problem that the working temperature of the power distribution cabinet rises under high temperature conditions.
