DETAILED DESCRIPTION

[0033] The following will be described in detail in combination with the accompanying Figures 1-7 The present application is further described in detail.

[0034] The present application discloses a ring main unit. Referring to Figure 1 A ring main unit comprises a cabinet body 1, the bottom of the cabinet body 1 is provided with a supporting leg 11, the bottom plate of the cabinet body 1 is provided with an air inlet hole 12, the top of the cabinet body 1 is provided with a first pipeline 2, one end of the first pipeline 2 is communicated with the cabinet body 1, the other end of the first pipeline 2 is rotatably connected with a second pipeline 3, the other end of the second pipeline 3 is provided with a third pipeline 4, the third pipeline 4 is perpendicularly arranged with the second pipeline 3, that is, the third pipeline 4 is horizontally arranged, the side wall of the third pipeline 4 is communicated with the second pipeline 3. One end of the third pipeline 4 is provided with a gas speed increasing mechanism 5, the side wall of the first pipeline 2 is fixedly provided with a driving structure 6, the driving structure 6 is electrically connected with a control module 7, the control module 7 is electrically connected with a wind direction detection assembly 8.

[0035] The wind direction detection assembly 8 is used to detect the wind direction, and sends an electrical signal to the control module 7 after detecting the wind direction. The control module 7 controls the driving structure 6 based on the received electrical signal, so as to drive the second pipe 3 to rotate, and the third pipe 4 is driven to rotate by the second pipe 3, and the gas speed-up mechanism 5 on the third pipe 4 is oriented to the direction in which the wind blows. The wind increases the speed after passing through the gas speed-up mechanism 5, at this time, the gas in the third pipe 4 is blown out at high speed, the air pressure in the third pipe 4 is reduced, the second pipe 3 is connected with the first pipe 2, the first pipe 2 is connected with the cabinet 1, and the air pressure in the cabinet 1 is higher than that in the third pipe 4, so the gas in the cabinet 1 is extracted and finally discharged from the third pipe 4, and the gas outside the cabinet 1 enters the cabinet 1 through the air inlet hole 12. At this time, the gas in the cabinet 1 flows, and at the same time, the heat generated by the heat generating components in the cabinet 1 is taken away, so as to realize heat dissipation in the cabinet 1. This heat dissipation method makes full use of natural wind energy, which is renewable, can reduce the consumption of non-renewable energy, and belongs to clean energy, which can reduce carbon emissions and environmental pollution. At the same time, the use of natural wind energy can also reduce financial expenditure, without the consumption of electric energy, thereby reducing the use cost. The combination of the wind direction detection assembly 8, the control module 7 and the driving structure 6 can realize automatic detection of the wind direction and orientation adjustment of the gas speed-up mechanism 5, that is, automatic real-time adjustment without manual intervention, which can adjust more timely, improve the utilization efficiency of wind, and reduce labor input and use cost.

[0036] With reference to Figure 2 The gas speed-up mechanism 5 at least includes first thin pipes 51, second thin pipes 52 and flared parts 53. The diameter of the first thin pipe 51 is smaller than that of the second thin pipe 52. Each second thin pipe 52 is connected to a first thin pipe 51, and the pipe diameter gradually changes at the connection. The end of the first thin pipe 51 away from the second thin pipe 52 is inserted into the third pipe 4, and the first thin pipe 51 fills the end of the third pipe 4. The flared part 53 is sleeved on the outer edge of all the second thin pipes 52, and the end of the flared part 53 with a larger diameter is away from the third pipe 4. In this embodiment, only the first thin pipe 51 and the second thin pipe 52 are taken as examples, and more thin pipes can be actually arranged, as long as the diameter of the thin pipe gradually decreases and the thinnest thin pipe is inserted into the third pipe 4, that is, a thin pipe with a larger diameter is connected to the end of the second thin pipe 52 away from the first thin pipe 51, and the same is true.

[0037] When the wind enters the thinner tube from the thicker tube, the flow rate can be increased, that is, the wind speed is increased, the wind with increased speed enters the third pipeline 4, and blows to the outlet at the other end of the third pipeline 4. At this time, because the flow rate of the gas in the third pipeline 4 is large, the air pressure here is small, and the air pressure in the connected cabinet 1 is the same as the ambient air pressure, so at this time the gas in the cabinet 1 will flow to the third pipeline 4, that is, the heat generated by the heating components in the cabinet can be taken away.

[0038] And for the gap between the first thin tube 51, the gap between the second thin tube 52 can also be plugged in the above manner. Thus the wind can be better blown into the first thin tube 51. The gap is not shown in the figure.

[0039] Referring to Figure 3 , the first pipeline 2 is provided with at least one bearing 21, and in this embodiment, one bearing 21 is taken as an example. The bearing 21 is installed on the first pipeline 2 away from the cabinet 1, and the installation mode is that the inner side wall of the bearing 21 is fixed with the outer wall of the first pipeline 2, and the inner wall of the second pipeline 3 is fixed with the outer side wall of the bearing 21. The end of the second pipeline 3 is provided with a sealing ring 31, and the inner edge of the sealing ring 31 is in close contact with the outer wall of the first pipeline 2.

[0040] Referring to Figure 3 and Figure 4 , the driving structure 6 includes a driving motor 61, a first fixing frame 62, a first driving tooth 63 and a first driven tooth 64. The first fixing frame 62 is fixed on the outer wall of the first pipeline 2, the driving motor 61 is fixed on the first fixing frame 62, the first driving tooth 63 is installed on the rotating shaft of the driving motor 61, the first driven tooth 64 is fixed on the outer wall of the second pipeline 3, the first driving tooth 63 and the first driven tooth 64 are engaged, and the driving motor 61 is electrically connected with the control module 7.

[0041] Referring to Figure 5 , the control module 7 is electrically connected with a wind direction detection assembly 8, which includes a second bracket 81, a first rotating rod 82, an indicating part 83 and a second encoder 84. The first rotating rod 82 is vertically arranged on the second bracket 81 and can rotate on the second bracket 81. The top end of the first rotating rod 82 is fixed with the indicating part 83, and the bottom end of the first rotating rod 82 is connected with the second encoder 84. The second encoder 84 is also fixed on the second bracket 81 and is electrically connected with the control module 7.

[0042] The wind direction detection assembly 8 can detect the wind direction, and by using the wind blowing indicating piece 83, the indicating piece 83 rotates to drive the second encoder 84, the control module 7 learns the angle of the indicating piece 83 based on the encoding position of the second encoder 84, and then analyzes the wind direction based on the angle of the indicating piece 83, and outputs a control signal based on the analyzed wind direction, so as to control the driving motor 61 to rotate, and then drive the second pipeline 3 to rotate through the first driving tooth 63 and the first driven tooth 64, so as to realize the control of the gas speed-up mechanism 5 to face the wind. By using the wind direction detection assembly 8, the wind direction can be automatically detected, so as to automatically control the rotation of the second pipeline 3, and the control process is completely automated, without human intervention, avoiding the situation that human control is not timely, and the labor input can also be reduced.

[0043] The cabinet 1 is internally provided with a plurality of temperature sensors, and the temperature sensors are electrically connected with the control module 7, that is, the control module 7 can learn the temperature condition in the cabinet 1 through the temperature sensors. The control module 7 can judge whether the temperature values are all less than the lower limit value based on the detected temperature values. If the temperature values are all less than the lower limit value, the control module 7 controls the driving motor 61 to rotate, so that the gas speed-up mechanism 5 does not face the wind, that is, the gas flow rate in the third pipeline 4 is reduced to a certain extent. When it is determined that the temperature values are all less than the lower limit value, it indicates that the temperature in the cabinet 1 is low at this time, so reducing the heat dissipation effect at this time will not have an impact, and after changing the angle of the gas speed-up mechanism 5, the possibility of dust and other small particulate matters in the environment entering the cabinet 1 can be reduced. The temperature values and the orientation angle of the gas speed-up mechanism 5 can be pre-set by the user, and can be set based on the heat generation condition in the cabinet 1 and the upper limit of heat dissipation, so as to better adapt to the actual use scene.

[0046] The blocking mechanism 103 comprises a baffle 1031, a connecting rod 1032, an electric push rod 1033 and a fixed plate 1034. The baffle 1031 is located between the second air cover interlayer 102 and the cabinet body 1. At least one connecting rod 1032 is fixed on the baffle 1031. In this embodiment, two connecting rods 1032 are fixed on the baffle 1031. The connecting rods 1032 penetrate the cabinet body 1 and are fixed with the fixed rod. One end of the electric push rod 1033 is fixed with the fixed plate 1034, and the other end of the electric push rod 1033 is fixed with the cabinet body 1. The control end of the electric push rod 1033 is electrically connected with the control module 7.

[0047] By using the blocking mechanism 103, the through hole 1021 on the second air cover base layer can be blocked, so as to change the airflow direction in the cabinet body 1. By blocking the through hole 1021 at a specific position, targeted heat dissipation can be realized. In combination with the temperature sensor, the control module 7 can automatically determine whether to perform targeted heat dissipation based on the temperature value detected by the temperature sensor. That is, the control module 7 determines by using the temperature value and different preset temperature thresholds. For the position with low temperature, the control module 7 blocks the through hole 1021 by using the blocking mechanism 103, so that the airflow flows through the position with high temperature as much as possible, so as to enhance the heat dissipation effect of the position with high temperature. In addition, by using the automatic detection and automatic control mode of the sensor, automatic control can be realized, the lag of manual operation can be avoided, the efficiency can be improved, and manual investment can be reduced, thereby reducing the cost.

[0048] Referring to Figure 1 The third pipeline 4 is curved upward at the end away from the gas speed increasing mechanism 5, and a plurality of heat absorbing rings 41 are fixed on the outer wall of the third pipeline 4. By using the heat absorbing rings 41 and the heat absorption of the third pipeline 4 itself, the temperature inside the third pipeline 4 is increased. Since the hot airflow flows upward, the gas in the third pipeline 4 rises and flows out from the curved upward end of the third pipeline 4, so as to drive the gas in the second pipeline 3 and the first pipeline 2 to flow, and further drive the gas in the cabinet body 1 to flow. The gas in the cabinet body 1 finally flows to the third pipeline 4 and flows out, so as to take away the capacity in the cabinet body 1, thereby achieving the heat dissipation effect. This mode can use solar energy to dissipate heat, reduce energy consumption, reduce environmental pollution and reduce use cost.

[0049] Referring to Figure 7Further comprising a first support 9, a first encoder 91, a first motor 92, a second fixed frame 93 and two solar panels 94, the edges of the two solar panels 94 are fixed to each other, and there is an included angle between the two solar panels 94, in this embodiment, the included angle is ninety degrees, the second fixed frame 93 is fixed with the two solar panels 94, one end of the rotating shaft of the first motor 92 is fixed with the second fixed frame 93, the first motor 92 is fixed on the first support 9, the other end of the rotating shaft of the first motor 92 is connected with the first encoder 91, the first encoder 91 is also fixed on the first support 9, and the first encoder 91 is electrically connected with the control module 7. One of the two solar panels 94 is a first solar panel 94, and the other is a second solar panel 94, the positive electrode of the first solar panel 94 is connected to the first electrode of the first motor 92, the negative electrode of the first solar panel 94 is connected to the second electrode of the first motor 92, the negative electrode of the second solar panel 94 is connected to the first electrode, and the positive electrode of the second solar panel 94 is connected to the second electrode.

[0050] The solar panel 94 can generate electricity when irradiated by sunlight. The above connection mode is that the positive and negative electrodes of the two solar panels 94 are crossed and then connected to the two electrodes of the first motor 92, and there is an included angle between the two solar panels 94. Only when the sun is on the vertical plane where the angle bisector of the included angle is located, the two solar panels 94 receive the same light and generate electricity in the same way. At this time, no pressure difference will be generated on the two electrodes of the first motor 92, that is, the positive electrode of the first solar panel 94 and the negative electrode of the second solar panel 94 generate a first voltage, the negative electrode of the first solar panel 94 and the positive electrode of the second solar panel 94 generate a second voltage, and the first voltage is equal to the second voltage, so there is no pressure difference on the first motor 92, and the rotating shaft of the motor will not rotate. When the sun moves, the power generation of the two solar panels 94 changes, and the solar panel 94 that receives more light generates more power than the other solar panel 94, so the first voltage is not equal to the second voltage, and a pressure difference is generated on the first motor 92 at this time, so the rotating shaft of the first motor 92 rotates and eventually rotates to the angle at which the two solar panels 94 receive the same light. Therefore, by using the above solar panel 94 and the matched components, the purpose of detecting the angle position of the sun can be achieved. Since the change of the angle position of the sun will cause the rotating shaft of the first motor 92 to rotate, the rotating shaft of the first motor 92 drives the first encoder 91, and the control module 7 obtains the encoding position of the first encoder 91, thereby obtaining the angle of the solar panel 94, and analyzing the angle position of the sun. The control module 7 outputs a control signal based on this to control the driving structure 6 to drive the second pipe 3 to rotate, so that the heat absorbing ring 41 can face the sun, thereby better absorbing heat, enhancing the effect of airflow rising, and achieving better heat dissipation effect in the cabinet 1.

[0051] The control module 7 is electrically connected with a wind speed detection sensor, the wind speed sensor can be arranged on the first support 9, the position is not limited, only an example is given, and the function effect can be realized. The wind speed detection sensor can detect the wind speed, and the control module 7 can judge after learning the wind speed.
