Description

Technical Field

[0001] The utility model relates to the technical field of electric power facilities, in particular to an outdoor intelligent box-type substation. Background Art

[0002] With the rapid development of economic construction and the acceleration of urbanization in my country, various types of business buildings, public supporting buildings and residential complexes are constantly emerging across the country: box-type substations, as supporting power facilities, have been widely used in various places. At present, box-type substations generally use side shutters for ventilation and heat dissipation. The structure is simple and the energy-saving effect is good. However, external dust can easily enter the interior of the box through the shutters, thereby affecting the safety of the internal electrical appliances. In order to improve the heat dissipation efficiency and the safety of use, fans and filters are installed inside. However, fans generally run uninterruptedly, resulting in high energy consumption. At the same time, filters generally require manual cleaning and maintenance, which makes use and maintenance inconvenient. For this reason, we propose an outdoor intelligent box-type substation.

[0008] Furthermore, the heat dissipation unit includes a ventilation component, spoiler 1 and spoiler 2, the ventilation component is arranged at the upper end of the box, spoiler 1 is symmetrically arranged at the left and right ends of the bottom surface of the box, spoiler 2 is symmetrically arranged at the left and right ends of the upper side wall of the box, the two spoiler 2 are located between the two spoiler 1s, and the front and rear ends of spoiler 1 and spoiler 2 are fixedly connected to the inner wall of the box to increase the air circulation speed and achieve efficient heat dissipation.

[0009] Furthermore, the heat dissipation unit also includes a filter screen, which is arranged at the upper end of the spoiler plate 1. The upper end of the filter screen is fixedly connected to the inner wall of the box body and can filter the air.

[0010] Furthermore, the ventilation assembly includes a support seat, a swivel, a fan and a servo motor. The support seat is arranged inside the circular through hole on the upper surface of the box body. The inside of the support seat swivel hole is rotatably connected with a rotating shaft. A swivel is provided between the two rotating shafts. The outer arc surface of the swivel is slidably connected to the inner arc wall of the support seat. A fan is provided inside the swivel. The servo motor is arranged inside the rectangular through hole on the upper surface of the box body.

[0014] Compared with the prior art, the beneficial effects of the utility model are: the outdoor intelligent box-type substation has the following advantages:

[0015] 1. During the working process, the temperature sensor detects the temperature inside the box. The temperature sensor can convert the temperature information into an electrical signal and transmit it to the single-chip microcomputer, so that the single-chip microcomputer can monitor the box in real time. When the temperature inside the box is greater than the preset value, the single-chip microcomputer will control the operation of the fan. The fan draws the hot air inside the box into the inside of the rain cap, and then the hot air passes through the protective net and is discharged to the outside. At the same time, the outside air enters the inside of the box through the heat dissipation holes and then moves upward along the spoiler plate 1 and then passes through the filter. Then the air moves downward along the spoiler plate 2 and replenishes from the bottom to the middle of the box and then is pumped to the outside by the fan, thereby realizing the circulation of air to cool the internal electrical components. During use, when the temperature is too high, the fan can be automatically started for cooling. At the same time, the air drawn in by the fan can be filtered by gravity and filtered by the filter to ensure the cleanliness of the cooling air, thereby greatly ensuring the safety of the substation.

[0016] 2. When the filter needs to be cleaned after long-term use, the single-chip microcomputer can be adjusted to control the operation of the servo motor. The output shaft of the servo motor drives the rotating ring to rotate 180 degrees through the rotating shaft. At the same time, the outer arc surface of the rotating ring will slide relative to the inner arc wall of the support seat. Then the single-chip microcomputer controls the operation of the fan and the dust removal motor. At this time, the fan will blow air downward. At the same time, the output shaft of the dust removal motor drives the convex column at the edge to make a circular motion through the disc. Then the convex column will slide and rotate relative to the long slide groove of the brush. The convex column will drive the brush to move along the sliding column. The brush will slide back and forth, and the bristles of the brush will rub against the surface of the filter screen, driving the dust attached to it to separate from the filter screen. At the same time, the airflow generated by the fan will blow the dust out to the outside through the heat dissipation holes, thereby realizing the self-cleaning of the filter screen. After cleaning, the microcontroller controls the output shaft of the servo motor to rotate in the opposite direction and reset, thereby resetting the fan. During cleaning and maintenance, the fan can automatically adjust the air outlet direction, and then cooperate with the reciprocating brush to automatically clean the filter screen, which not only ensures safety during cleaning, but also greatly reduces the labor burden of maintenance personnel.
