[0022] As Figures 1 to 14 shown in the internal and external intelligent isolation box-type substation, which includes a box body main body 1, a base 2 provided below the box body main body 1, and at least one group of box doors 3 provided on the side wall of the box body main body 1, and temperature and humidity sensors are provided both inside and outside the box body main body 1. On this basis, the box-type substation further includes: an air curtain assembly 4, a wind guiding assembly 5, a driving assembly and a controller; the air curtain assembly 4 is provided at the top of the box door 3 and includes a first air curtain 41 and a second air curtain 42 arranged side by side in the thickness direction of the box door 3. The second air curtain 42 is arranged on the inner side, and the first air curtain 41 is arranged on the outer side. The outlet of the first air curtain 41 communicates with the hollow cavity of the box door 3; the wind guiding assembly 5 is provided in the base 2 and below the box door 3 and includes a first wind guiding box 51 and a second wind guiding box 52 arranged side by side with the first wind guiding box 51 in the width direction of the box door 3; the driving assembly includes a first driving member connected to the first wind guiding box 51 and a second driving member connected to the second wind guiding box 52. The first driving member is used to drive the first wind guiding box 51 to move to form a first transition cavity 51a with the side wall of the base 2, and the second driving member is used to drive the second wind guiding box 52 to move to form a second transition cavity 52a with the side wall of the base 2; the controller is used to receive the signals of the temperature and humidity sensors and control the actions of the first driving member and the second driving member; Among them, the first wind guiding box 51 includes a first cavity 511 below the first air curtain 41 and a second cavity 512 below the second air curtain 42, and a third cavity 513 communicating with the second cavity 512 is provided directly below the first cavity 511. The second wind guiding box 52 is provided with a through groove 521 on the side close to the box door 3, and a first channel 61 and a second channel 62 are provided on the cross beam 6 between the first wind guiding box 51 and the second wind guiding box 52; The airflow of the first air curtain 41 is sprayed onto the first cavity 511, flows through the second transition cavity 52a via the first channel 61 and is discharged outdoors, while the airflow of the second air curtain 42 flows through the second cavity 512, passes through the box body 1 and enters the room to form a first circulation path; The airflow of the second air curtain 42 is sprayed onto the first cavity 511, enters the second air guide box 52 via the second channel 62 and is discharged outdoors, while the airflow of the first air curtain 41 enters the first transition cavity 51a, flows through the third cavity 513, passes through the second cavity 512 and enters the box body 1, and is discharged into the room to form a second circulation path.

[0023] In the present invention, after receiving the signals from the temperature sensors and humidity sensors inside and outside the room, the controller (not shown in the figure) controls the actions of the first driving member and the second driving member, so that the first air guide box 51 and the second air guide box 52 are always arranged in a staggered manner to realize the switching between the first circulation path and the second circulation path. The specific implementation process is as follows: when the temperature and humidity need to be adjusted in the substation, if the temperature and humidity in the substation are less than or equal to the outdoor environment, the first circulation path is selected to realize the independent circulation of the indoor and outdoor circulations, and the temperature and humidity are adjusted through the indoor circulation without directly introducing external air, which helps to maintain the stability of the internal environment of the substation; if the temperature and humidity in the substation are higher than the outdoor environment, the second circulation path is selected to realize the indoor and outdoor circulation flow, and external air is introduced and indoor air is discharged through the combination of indoor and outdoor circulations to achieve the purpose of cooling or dehumidifying. Through the setting of the first air curtain 41 and the second air curtain 42, the present invention forms a double-layer airflow isolation, effectively blocking the entry of external hot air or moisture into the box body, and intelligently adjusting the states of the first air guide box 51 and the second air guide box 52 through the controller, realizing the effective flow of internal air and the reasonable utilization of external air, effectively reducing the aging speed of insulating materials and extending the service life of the equipment in the substation.

[0024] In the present invention, the first driving member and the second driving member adopt one of the driving forms of air cylinders or oil cylinders, but are not limited to the above two driving structures. In addition, in the present invention, at least one blower (not shown in the figure) is used to supply air to the first air curtain 41 and the second air curtain 42 to ensure that the formed air curtain has sufficient blocking effect. Specifically, when the temperature and humidity in the substation are normal, the blower does not work, while when the temperature and humidity in the substation need to be adjusted, the blower starts to work. During the air supply process of the blower, the rotational speed of the blower can be appropriately adjusted to increase the air flow rate, form a stronger air flow barrier, and at the same time accelerate the air circulation speed, so as to more quickly restore the temperature and humidity in the substation to the normal working range. In addition, the first air curtain 41 and the second air curtain 42 can also be provided with separate blowers for air supply, which can increase the air flow rate of the second air curtain 42 during the separate indoor and outdoor circulation, thereby accelerating the internal circulation flow speed and realizing the temperature and humidity adjustment inside the substation. When circulating indoors and outdoors, the air flow rate of the second air curtain 42 is increased to form a negative pressure inside the substation, indirectly accelerating the air flow speed of the second air curtain 42, and thus accelerating the flow speed of the entire air flow circulation.

[0025] In the present invention, when the air flow of the first air curtain 41 enters the first cavity 511 through the cavity of the box door 3 and enters the second transition cavity 52a through the first channel 61. Since the second transition cavity 52a is in communication with the second air guide box 52, a large amount of air flow entering the second transition cavity 52a will converge into the second air guide box 52, while a small amount of air flow will flow to the outside. The air flow converging in the second air guide box 52 forms a turbulent flow phenomenon, resulting in a slower flow speed of the first air curtain 41 in the base 2, seriously affecting the partition effect of the first air curtain 41. Therefore, preferably, as Figures 9 - 11 shown, a flexible guiding plate 522 is provided on the outer side surface of the second air guide box 52 near one end of the first air guide box 51, and the flexible guiding plate 522 is inclined. This is to directly and quickly guide the gas flowing out of the first cavity 511 to the air outlet, avoid the gas from flowing back into the second air guide box 52, and effectively accelerate the gas outflow speed. When the second circulation path needs to be opened, the second air guide box 52 will move towards the direction of the box door 3 under the action of the second driving member until the second air guide box 52 abuts against the side wall of the base 2 on the side of the box door 3. At this time, the flexible guiding plate 522 is pressed and attached to the second air guide box 52 to connect the first cavity 511 with the second air guide box 52.

[0026] In the preferred embodiment of the present invention, as Figures 12 - 13As shown, the partition plate 514 between the first cavity 511 and the second cavity 512 is inclined downward towards the second air guide box 52, so that the length of the airflow sprayed onto the partition plate 514 increases in sequence, while the airflow velocity on the partition plate 514 gradually decreases. After the airflow at the highest point of the inclination sprays onto the inclined partition plate 514, a part of it will be shunted towards the inclined direction, thereby guiding the airflow sprayed onto the partition plate 514 below, so as to accelerate the discharge speed of the airflow on the inclined surface of the partition plate 514. At the same time, the second cavity 512 located below the first cavity 511 is a triangular cavity, and the airflow entering the second cavity 512 will generate turbulence, increasing the contact area and time between the air and the cavity wall surface, so that the air can more effectively absorb or release heat when passing through the triangular cavity, and pre-cool and dehumidify the outdoor air before the outdoor air enters the room, so as to quickly adjust the temperature and humidity in the room.

[0027] As Figure 7 shown, in order to ensure the air circulation in the substation, a number of grille holes 31 are provided on the inner and outer side walls of the box door 3, and are arranged towards the outdoor side; while ensuring the outward flow of the internal gas, the entry of external gas into the substation is reduced. Since the airflow ejected by the first air curtain 41 will enter the lower first air guide box 51 through the cavity inside the box door 3, and the airflow of the second air curtain 42 is directly sprayed onto the first air guide box 51, therefore, in order to reduce the influence of the airflow of the first air curtain 41 on the airflow stability of the second air curtain 42, a number of grille holes 31 are inclined downward to prevent the airflow of the first air curtain 41 from mixing into the airflow of the second air curtain 42, effectively ensuring the internal circulation of the airflow of the second air curtain 42 in the box body 1.

[0028] As Figures 3 - 6 shown, the base 2 includes a frame 21, a bottom plate 22 and a top plate 23; the bottom plate 22 and the top plate 23 are arranged in parallel on the frame 21, and an air curtain air inlet 231 is provided at the position of the top plate 23 corresponding to the air curtain assembly 4, and an indoor air outlet 232 is provided at the position corresponding to the second cavity 512; the width of the air curtain air inlet 231 is greater than the width of the first cavity 511, so that the first air curtain 41 realizes outdoor circulation through the first cavity 511, and at the same time the second air curtain 42 can enter the second cavity 512 through the air inlet and be ejected from the indoor air outlet 232, which helps to form an effective air circulation system, and by controlling the air inlet and outlet, the indoor air quality and temperature can be effectively controlled, providing a more comfortable climate condition for the use environment.

[0029] As a preference of the above embodiment, filter screens 24 are provided on both the air curtain air inlet 231 and the indoor air outlet 232. The filter screens 24 are arranged on the floor, so that the airflow of the air curtain must pass through the filter screens 24 to enter and exit, playing a dual filtering mechanism, effectively improving the air quality and further improving the indoor airflow distribution.

[0030] AsFigure 3 As shown, an outdoor air outlet 233 is provided on the side wall of the base 2 corresponding to the through slot 521 of the second air guide box 52; it can directly discharge the indoor air to the outside, effectively isolating the indoor and outdoor air environments. The outside of the outdoor air outlet 233 is in a grid structure, preventing external sundries from entering the air guide system and reducing the impact of bad weather conditions such as strong winds and rain on the system.

[0031] In the present invention, the inlet of the third cavity 513 is arranged on the side surface of the first air guide box 51 away from the second air guide box 52 and penetrates through to the second cavity 512. By aligning the inlet and outlet of the third cavity 513, the gas in the first transition cavity 51a is rectified and then discharged into the second cavity 512, so that the airflow entering the second cavity 512 flows along a straight path, improving the flow efficiency.

[0032] In the present invention, under the alternating driving action of the driving component, the first air guide box 51 and the second air guide box 52 realize the switching with the air circulation system. Preferably, as Figure 9 shown, the first channel 61 and the second channel 62 are arranged on the same horizontal line along the driving direction of the driving component. When the first cavity 511 communicates with the second air guide box 52 through the second channel 62, the side wall of the second air guide box 52 blocks the first channel 61 to form the first transition cavity 51a. Similarly, when the first cavity 511 directly discharges to the outside through the second transition channel, the second air guide box 52 blocks the second channel 62, so that the airflow of the second air curtain 42 passes through the second cavity 512 and is discharged into the room.

[0033] The present invention also provides a use method of an indoor and outdoor intelligent isolation box-type substation, including the following steps: When the substation is working normally, the temperature and humidity sensors located inside and outside the box body 1 of the substation monitor the indoor and outdoor temperature and humidity in real time and transmit them to the controller; When the temperature and humidity need to be adjusted inside the substation, if the temperature and humidity inside the substation are less than or equal to the outdoor environment, the first driving member is started. The first driving member drives the first air guide box 51 to move towards the box door 3. At this time, the second air guide box 52 and the side wall of the base 2 form a second transition cavity 52a. The first air curtain 41 sequentially passes through the box door 3, the first cavity 511 and the second transition cavity 52a and then is discharged to the outside, while the airflow of the second air curtain 42 passes through the second cavity 512 and then enters the room to adjust the indoor temperature and humidity, realizing the independent circulation of indoor circulation and outdoor circulation; When the temperature and humidity inside the substation are higher than those of the outdoor environment, the second driving member is activated. The second driving member drives the second air guide box 52 towards the box door 3. At this time, a first transition cavity 51a is formed between the first air guide box 51 and the side wall of the base 2. The air flow of the first air curtain 41 sequentially passes through the box door 3, the first transition cavity 51a, and the third cavity 513 and enters the second cavity 512, and finally is discharged into the room. The air flow of the second air curtain 42 enters the interior of the second air guide box 52 through the first cavity 511 and is discharged outdoors through the through slot 521, so as to realize the circulating flow between the indoors and outdoors.

[0034] The system can automatically adjust according to the actual conditions of the indoor and outdoor environments to ensure the environmental stability inside the substation. This automated monitoring and adjustment mechanism greatly improves work efficiency and reduces the consumption of human resources. Through the design of the automated control system, the possibility of human operation errors is reduced, the overall reliability and stability of the system are improved. At the same time, the self-adjusting ability of the system enables it to cope with changes in the external environment and ensure the continuous stability of the environment inside the substation.

[0035] Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
