Description

Technical Field

[0001] This utility model belongs to the technical field of transformer box equipment, specifically relating to a flip-top ventilation device. Background Technology

[0002] The structure of transformer substations requires ventilation systems. Heat generated during operation must be quickly dissipated through these systems to maintain a suitable temperature environment. Furthermore, for substations located in areas prone to sandstorms and snowstorms, ventilation systems must also prevent sand and snow from entering and affecting operation. Rainwater can also enter the substations through the ventilation system, potentially impacting operation. Currently, the lack of such structural features adequately addresses these diverse application scenarios. Utility Model Content

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0030] Example:

[0031] like Figure 1-4 As shown, this embodiment provides a flip-top ventilation device, including a bottom frame 1, an outer cover 2, a support assembly, a ventilation mesh 15, a door lock assembly, and a connecting assembly;

[0032] One end of the bottom frame 1 is hinged to one end of the outer cover 2, and the other end of the bottom frame 1 is detachably connected to the other end of the outer cover 2 through a door lock assembly;

[0033] One end of the support component is hinged to the inner wall of the outer cover 2, and the other end of the support component is detachably connected to the bottom frame 1 through a connecting component;

[0034] When the other end of the bottom frame 1 is separated from the other end of the outer cover 2, and the other end of the support component is connected to the bottom frame 1, the two ends of the ventilation mesh plate 15 are respectively connected to the other ends of the bottom frame 1 and the outer cover 2.

[0035] The flip-top ventilation device of this embodiment is used to install at the ventilation opening of the outdoor transformer substation. When ventilation is required, the other end of the bottom frame 1 and the other end of the outer cover 2 can be separated by the door lock assembly and rotated relative to each other. Then, the support assembly is rotated and the other end of the support assembly is connected to the bottom frame 1 by the connecting assembly. Finally, the ventilation mesh plate 15 is installed to realize the open state of the flip-top ventilation device. Conversely, the flip-top ventilation device can be closed by performing the reverse operation, thereby preventing harmful substances from entering the transformer substation in harsh environments such as strong winds, heavy dust, storms, and snow.

[0036] The specific structure of the bottom frame 1 in this embodiment is as follows: a ventilation section 3 is provided on the bottom frame 1.

[0037] Meanwhile, several mounting holes 4 are provided on the bottom frame 1 and around the ventilation section 3.

[0038] In the above structure, the bottom frame 1 is a structure connected to the ventilation opening of the outdoor transformer substation. The ventilation part 3 of the bottom frame 1 is set to correspond to the ventilation opening of the outdoor transformer substation. The mounting hole 4 is provided with a mounting part that can be connected to the outdoor transformer substation.

[0039] The specific connection structure between the bottom frame 1 and the outer cover 2 in this embodiment is as follows:

[0040] The two are connected by a door lock assembly, which includes a door lock seat 5, a door lock bolt 6 and a door lock plate 7. The door lock seat 5 is located on the outer cover 2. The door lock bolt 6 is threadedly engaged with the door lock seat 5. The door lock plate 7 is connected to one end of the door lock bolt 6. The other end of the outer cover 2 is provided with a limiting plate 8 that can abut against the door lock plate 7.

[0041] When the bottom frame 1 and the outer cover 2 rotate, and the other end of the bottom frame 1 approaches the other end of the outer cover 2, the operator can rotate the door lock bolt 6, causing the door lock plate 7 to rotate relative to the door lock seat 5, and causing the door lock plate 7 to abut against the limiting plate 8 at the other end of the outer cover 2, so that the bottom frame 1 and the outer cover 2 are locked and closed. Conversely, the operation is reversed to unlock the two and open the outer cover 2.

[0042] The specific structure of the connection component in this embodiment is as follows:

[0043] It includes a connecting seat 9, a pin 10, and a spring. The connecting seat 9 is located on the bottom frame 1. The pin 10 is slidably engaged with the connecting seat 9. Both ends of the spring are connected to the pin 10 and the connecting seat 9, respectively. When the spring is in its natural state, one end of the pin 10 extends out of the connecting seat 9. When the spring is in its compressed state, one end of the pin 10 is inside the connecting seat 9.

[0044] The support assembly is provided with a limiting hole 13 that can cooperate with one end of the pin 10.

[0045] The specific structure of the supporting components is as follows:

[0046] It includes two support plates 11 symmetrically arranged on both sides of the inner wall of the outer cover 2, and the number of connecting components is two and corresponds to the position of the support plates 11;

[0047] The support plate 11 is provided with a limiting protrusion 12, and the limiting hole 13 is provided with a limiting protrusion 12;

[0048] The bottom frame 1 is provided with an insertion hole 14 that can cooperate with the limiting protrusion 12.

[0049] The operator rotates the support plate 11 so that the limiting protrusion 12 on the support plate 11 is close to the connecting component. Then, the operator adjusts the relative angle between the bottom frame 1 and the outer cover 2 so that the limiting protrusion 12 engages with the insertion hole 14. The operator pulls the pin 10 so that one end of the pin 10 is inside the connecting seat 9. Then, the operator releases the pin 10 so that one end of the pin 10 engages with the limiting hole 13. The above structure achieves double limiting of the support plate 11, ensuring the stability of the support plate 11 in supporting both the bottom frame 1 and the outer cover 2.

[0050] The ventilation mesh plate 15 of this embodiment is provided with a plurality of ventilation mesh holes 16.

[0051] Meanwhile, a bent portion 17 that abuts against the bottom frame 1 is provided at one end of the ventilation mesh plate 15, and a bent plate 18 that abuts against the other end of the outer cover 2 is provided at the other end of the ventilation mesh plate 15. The above structure can make the ventilation mesh plate 15 stably fixed between the outer cover 2 and the bottom frame 1.

[0052] In summary, the structure of this embodiment is reasonably designed and easy to operate, enabling operators to conveniently and reliably close the ventilation channels even in harsh environments, preventing external damage to the inside of the transformer substation and providing a reliable guarantee for its safe operation.

[0053] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
