Description

Technical Field

[0001] The utility model relates to the technical field of transformer substations, in particular to a box-type transformer substation with a ventilation structure. Background Art

[0002] Box-type substation, also called prefabricated substation or prefabricated substation, is a kind of factory-prefabricated indoor and outdoor compact distribution equipment that integrates high-voltage switchgear, distribution transformers and low-voltage distribution devices according to a certain wiring scheme.

[0003] According to a ventilation structure for an intelligent box-type substation mentioned in Chinese utility model 202220637746.3, the ventilation structure for the intelligent box-type substation, when in use, delivers external wind from the air inlet pipe into the connecting pipe through the air suction component, and then delivers cold air to the surrounding of the connecting pipe through the air outlet. Since the connecting pipe is located at the center position of the base, the cold air diverges from the middle to the outside, and at the same time, cooperates with the ventilation window to make the heat dissipation of electrical equipment more uniform. However, the ventilation structure for the intelligent box-type substation does not have an automatic opening and closing structure when in use, resulting in external dust entering the interior of the substation when ventilation is not required, and moisture on rainy days enters the interior of the substation, affecting the various dust-proof mechanisms inside the substation. Therefore, it is necessary to propose a box-type substation with a ventilation structure to solve the above-mentioned problems. Utility Model Content

[0010] Furthermore, the gear ring is fixedly mounted on the outside of the rotating ring, and a transformer substation is fixedly mounted on one side of the ventilation cylinder and the protective cylinder.

There are five groups of adjustment plates, and sealing gaskets are provided on the contact surfaces of the five groups of adjustment plates.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] The box-type substation with a ventilation structure is provided with an opening and closing structure. When in use, by starting the driving motor, the output shaft of the driving motor will drive the gears to engage with the gear rings, thereby driving the swivel to rotate outside the ventilation duct.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The opening and closing structure 6 includes a first support bearing 601, the first support bearing 601 is fixedly installed inside the fixed plate 4, the second support bearing 603 is fixedly installed inside the ventilation tube 1, and a connecting rod 602 is movably installed inside the first support bearing 601 and the second support bearing 603. A connecting tube 604 is fixedly connected to one end of the connecting rod 602, and a limited rotation plate 606 is fixedly connected to one side of the connecting tube 604.

[0022] In specific implementation, by setting the opening and closing structure 6, when in use, by starting the driving motor 301, the output shaft of the driving motor 301 will drive the gear 302 to engage with the gear ring 303, so as to drive the swivel 2 to rotate outside the ventilator 1. When the swivel 2 rotates, it will drive the positioning rod 605 to rotate horizontally, and because the positioning rod 605 passes through the limiting through hole 608, the limiting rotating plate 606 is further driven by the positioning rod 605 to change the angle. When the limiting rotating plate 606 rotates, it will drive the connecting tube 604 to rotate. When the connecting tube 604 rotates, it will drive the connecting rod 602 to rotate inside the first support bearing 601 and the second support bearing 603. When the connecting rod 602 rotates, it will drive the adjusting plate 5 to adjust the angle, so as to achieve the effect of gas communication between the ventilator 1 and the outside world. The larger the rotation angle of the adjusting plate 5, the more gas passes through the ventilator 1, thereby controlling the opening and closing of the gas connection channel of the ventilator 1.

[0023] The ventilator 1 is an existing technical means, and a ventilation fan is arranged inside the ventilator 1. The operation of the ventilation fan and the driving motor 301 are connected to the same switch circuit.

[0024] When implementing, follow these steps:

[0025] 1) First, through the action of the rotating structure 3;

[0026] 2) Then, by starting the driving motor 301, the output shaft of the driving motor 301 drives the gear 302 to mesh with the gear ring 303, thereby driving the rotating ring 2 to rotate outside the ventilator 1;

[0027] 3) When the rotating ring 2 rotates, the positioning rod 605 will be driven to rotate horizontally, and the positioning rod 605 passes through the limiting through hole 608;

[0028] 4) Finally, the positioning rod 605 is used to further drive the limit rotating plate 606 to change its angle. When the limit rotating plate 606 rotates, it will drive the connecting tube 604 to rotate. When the connecting tube 604 rotates, it will drive the connecting rod 602 to rotate inside the first support bearing 601 and the second support bearing 603. When the connecting rod 602 rotates, it will drive the adjustment plate 5 to adjust its angle, thereby achieving the effect of gas connection between the ventilation duct 1 and the outside world, and then being able to control the opening and closing of the gas connection channel of the ventilation duct 1.

[0029] In summary, the box-type substation with a ventilation structure is provided with an opening and closing structure 6. When in use, by starting the driving motor 301, the output shaft of the driving motor 301 will drive the gear 302 to engage with the gear ring 303, so as to drive the swivel 2 to rotate outside the ventilation duct 1. When the swivel 2 rotates, it will drive the positioning rod 605 to rotate horizontally, and because the positioning rod 605 passes through the limiting through hole 608, the limiting rotating plate 606 is further driven by the positioning rod 605 to change its angle. When the limiting rotating plate 606 rotates, it will drive the connecting tube 604 to rotate. When the connecting tube 604 rotates, it will drive the connecting rod 602 to rotate inside the first support bearing 601 and the second support bearing 603. When the connecting rod 602 rotates, it will drive the adjusting plate 5 to adjust its angle, so as to achieve the effect of gas communication between the ventilation duct 1 and the outside world. The larger the rotation angle of the adjusting plate 5, the more it can control the opening and closing of the gas connection channel of the ventilation duct 1.
