The outdoor high-voltage power distribution cabinet is given by figures 1-3, and comprises a power distribution room 1 and is characterized in that a power storage room 2 is arranged above the power distribution room 1, a control room 3 is arranged on the left side of the power distribution room 1, the outer wall of the power storage room 2 is transparent, a solar cell panel 4 is fixedly arranged in the power storage room 2, the outer wall of the transparent power storage room 2 is favorable for sunlight to irradiate on the solar cell panel 4, the utilization area of the solar cell panel 4 is increased, a storage battery 6 and a charge-discharge controller 5 which are connected through a lead are fixedly arranged on the uppermost layer of the control room 3, the solar cell panel 4 is connected with the charge-discharge controller 5 through a lead, the storage battery 6 is used for storing electric energy converted by the solar cell panel 4, an independent inverter 7 is used for converting direct current directly obtained by the solar cell panel 4 into alternating current for alternating current load, and an independent inverter 7 and a charging-discharging controller, A first fan 9 and a second fan 10, a charge and discharge controller 5 is connected with an independent inverter 7 through leads, the independent inverter 7 is respectively connected with the first fan 9 and the second fan 10 through leads, the charge and discharge controller 5 is also connected with a temperature sensor 12 positioned in the power distribution room 1 through leads, a preset value is set for the temperature sensor 12, when the temperature sensor 12 monitors that the temperature in the power distribution chamber 1 is higher than or lower than a preset value, a signal is transmitted to the charge-discharge controller 5, an air outlet of the first fan 9 is communicated with an air pipe 13 positioned in the power distribution chamber 1, an inner air window 15 positioned below the air pipe 13 is arranged on the side wall of the power distribution chamber 1, an air outlet of the air pipe 13 is positioned on the inner air window 15, the air outlet of the second fan 10 is communicated with the distribution room 1 through the inner air window 15, an air curtain outlet 14 located below the inner air window 15 is formed in the bottom of the distribution room 1, and an air outlet window 16 is formed in the upper portion of one side, deviating from the air pipe 13, of the distribution room 1. The solar panel 4 converts light energy into electric energy, the electric energy converted is controlled by the charge and discharge controller 5 to be stored in the storage battery pack 6, direct current in the storage battery pack 6 is controlled by the charge and discharge controller 5 to be input into an inverter to be converted into alternating current, the temperature sensor 12 is a direct current load and is directly connected with the charge and discharge controller 5, the first fan 9 and the second fan 10 are alternating current loads, and the direct current is converted into alternating current through the independent inverter 7 and then supplies power to the first fan 9 and the second fan 10;
after the first fan 9 is started, air is sent into the air pipe 13, the air pipe 13 outputs the air to form an air curtain which is blocked at an inner air window 15 and then is output to the outside from an air curtain outlet 14, and dust and insects are prevented from entering the power distribution room 1; when the second motor starts, wind blows into the power distribution cabinet through the inner wind window 15, and heat in the power distribution cabinet is upward along with airflow and is output from the air outlet.
The control room 3 is provided with a first outer air window 8 positioned beside the first fan 9 and a second outer air window 11 positioned beside the second fan 10, and the first outer air window 8 and the second outer air window 11 are both provided with filter screens. The first fan 9 and the second fan 10 both generate strong wind suction force during working, and the filter screen can effectively prevent impurities in the outside air from entering the fans, so that the service life of the fans is prolonged.
And filter screens are respectively arranged on the air curtain outlet 14 and the air outlet window 16. The air curtain outlet 14 is not only used for outputting an air curtain, but also can play a role of serving as an air inlet of natural wind during natural ventilation, and a filter screen is added to prevent small animals from entering the distribution room 1 because the air curtain outlet 14 is positioned at the bottom of the distribution room.
The inner diameter of the air pipe 13 is gradually reduced from the air inlet to the air outlet, the air outlet of the air pipe 13 is in a shape of a long and thin gap, the air outlet of the air pipe 13 is tightly attached to the upper edge of the inner air window 15, the direction of the upper edge is vertical and downward, the air curtain outlet 14 faces the air outlet of the air pipe 13, and the width of the air curtain outlet 14 is larger than that of the air outlet of the air pipe 13. The air curtain blows downwards, the speed is attenuated and the air curtain diffuses to the side, so that the air speed in the horizontal direction is generated, the dust and insects can be effectively prevented from entering the air curtain only when the horizontal air speed of the air curtain is larger than the air speed of natural wind, the volume flow of the wind has a direct relation with the air speed and the sectional area of the air pipe 13, the total flow of the wind is unchanged when the power of the fan is unchanged, and the air speed is increased when the sectional area of the air outlet of the air pipe 13 is reduced.
The first fan 9 and the second fan 10 are not started simultaneously. When natural ventilation is carried out, the first fan 9 is started, the second fan 10 is stopped, air with high temperature in the power distribution room 1 rises due to low density and is discharged from the air outlet, air with low temperature and high density outside enters the power distribution room 1 through the inner air window 15 and the air curtain outlet 14, the second fan 10 does not influence the entering of the outside air in the process, and air blown in by the first fan 9 forms an air curtain through the air pipe 13 to prevent dust and insects in natural wind from entering; when the machine is ventilated, the first fan 9 is stopped, the second fan 10 is started, the air curtain is ensured not to influence the wind sent by the second fan 10, and the process can be realized by a programmable controller without limitation.
And foot pads 17 are fixedly arranged below the power distribution room 1 and the control room 3. Different from the existing power distribution cabinet, because the air curtain outlet 14 is arranged at the bottom of the power distribution room 1, the pad feet 17 are required to be added to improve the whole cabinet body, and enough output space flows out for the air curtain.
When the utility model is used, when the temperature in the distribution room 1 does not reach the preset value of the temperature sensor 12, natural ventilation is adopted, hot air in the distribution room 1 is output from the air outlet window 16, the outside air enters the distribution room 1, so that the air flow is formed to cool the distribution room 1, and meanwhile, the first fan 9 starts the air pipe 13 to output an air curtain to block dust and insects; after the temperature in the electricity distribution room 1 reaches the preset value of the temperature sensor 12, mechanical ventilation is adopted, the second fan 10 is started, and outside air is sent into the electricity distribution room 1 through mechanical force to perform forced air circulation.
The utility model has the advantages that: compared with the innovation point that the solar energy is adopted to complete the self power supply of the ventilation equipment in the prior art, the solar ventilation equipment has the advantages of energy conservation, environmental protection, change of ventilation form along with the real-time condition and excellent ventilation effect.
