Technical Field

[0001] This invention relates to the field of power equipment technology, and in particular to a prefabricated substation. Background Technology

[0002] With the continuous development of society, the application of electricity is becoming more and more widespread. Box-type substations, also known as prefabricated substations, are a type of equipment that connects high-voltage switchgear, distribution transformers and low-voltage distribution devices, playing an important role in power transmission.

[0003] To address this, patent CN108199275A discloses a dustproof self-cleaning box-type substation equipment, including a protective box, a dust filter box, an electrical equipment box, a cleaning fan, an exhaust fan, an intake fan, and a dust filter bag. An air inlet is located at the bottom of the left side panel of the protective box, and an intake fan is installed inside the air inlet. The upper part of the inner cavity of the dust filter box is connected to the outer end of the air inlet. A partition is fixedly mounted in the middle of the inner cavity of the dust filter box, and a vent pipe is located in the middle of the partition. The dust filter bag covers the outside of the vent pipe. An air jet pipe is located on the top plate of the inner cavity of the dust filter box, and the other end of the air jet pipe is connected to the outlet of the cleaning fan. An exhaust fan is located at the end of the exhaust hole on the inner side panel of the protective box. This invention has a simple and stable structure, good heat dissipation, effectively prevents dust from entering the protective box, and facilitates the removal of dust adsorbed on the dust filter bag, achieving automatic cleaning and reducing manpower and material resources.

[0004] The aforementioned dustproof and self-cleaning box-type substation equipment has poor anti-theft performance during outdoor use, making it easy for electrical equipment to be stolen or damaged due to lock picking, resulting in low security during use. Summary of the Invention

The movable groove is located in the first door panel. On the side of the interior near the second door panel, a positioning groove is provided inside the first door panel on the top side of the movable groove, a first sliding groove is provided inside the first door panel on the top side of the movable groove, and a second sliding groove is provided inside the first door panel on the other side of the bottom of the movable groove. A first sliding rod is provided inside the first sliding groove, and a second sliding rod is provided inside the second sliding groove. A rotating seat is hinged inside the movable groove, and hinge rods are hinged at both ends of the rotating seat. A lock cylinder is provided inside the positioning groove, and a limit pin is provided on one side of the lock cylinder, with one end of the limit pin extending into the interior of the first sliding rod. A push-out spring is provided on the outside of the limit pin.

[0010] Preferably, both the first door panel and the second door panel are installed on both sides of the housing via hinges, and one side of the first door panel and one side of the second door panel are designed to be interlocked.

[0011] Preferably, the protective structure includes thermal insulation cotton, thermal insulation board, and sound insulation board. The thermal insulation cotton is disposed on the outside of the metering cabinet and transformer cabinet inside the box. The thermal insulation board is disposed on the outside of the thermal insulation cotton, and the sound insulation board is disposed on the inside of the thermal insulation cotton.

[0012] Preferably, the heat dissipation structure includes an exhaust pipe, an intake pipe, and a cooler. The exhaust pipe is installed at one end inside the vent, the cooler is installed at the other end inside the vent, and the output end of the cooler is equipped with an intake pipe.

[0013] Preferably, one end of the exhaust pipe is fixedly connected to the inner side wall of the canopy at one end of the vent, and the other end of the exhaust pipe extends to the top of the housing.

[0014] Preferably, the input end of the air cooler is fixedly connected to the inner wall of the roof at one end of the vent, and the end of the air inlet pipe away from the air cooler extends to the bottom of the housing.

[0015] Preferably, the lock cylinder is externally connected to a door lock, and the lock cylinder and the second door panel are fixedly connected to each other through the door lock.

[0016] Preferably, the limiting pin and the ejection spring form a telescopic structure, the first slide groove is located directly below the first limiting groove, and the second slide groove is located directly above the second limiting groove.

[0017] Preferably, the top end of the first sliding rod and the top end of the first door panel are located in the same plane, and the bottom end of the second sliding groove and the bottom end of the first door panel are located in the same plane.

[0019] The present invention provides a box-type substation, which has the following advantages:

[0020] By incorporating an anti-theft structure, when the lock cylinder is damaged and removed from the positioning groove, the limiting pin moves to the outside of the first sliding rod under the elastic force of the push-out spring. At this time, the second sliding rod slides downward inside the second sliding groove. Simultaneously, the second sliding rod drives the first sliding rod to slide upward inside the first sliding groove through the hinge rod and rotating seat, causing the top end of the first sliding rod to move into the first limiting groove and the bottom end of the second sliding rod to move into the second limiting groove. Under the interlocking action of the first and second sliding rods, the first door panel and the box body are fixed together, preventing the loss or damage of electrical equipment due to damage to the lock cylinder. This enhances the anti-theft performance of the device and improves the safety of the box-type power equipment during use.

[0021] With the protective structure and the sound insulation board, the noise generated by the electrical equipment inside the box is reduced. With the insulation cotton and insulation board, the heat insulation performance of the box is enhanced, the temperature difference between the inside and outside of the box is reduced, thereby reducing the workload of the air cooler and improving the energy efficiency of the box-type power equipment during use.

[0022] By incorporating a heat dissipation structure, when the air cooler is activated, the air cooler delivers dust-removed air into the bottom of the enclosure through the air inlet pipe. The hot air inside the enclosure rises and is discharged to the outside of the enclosure through the exhaust pipe, thus achieving the function of easy heat dissipation and improving the convenience of using the box-type power equipment.
