Description

Technical Field

[0001] The utility model relates to the technical field of ventilation devices, in particular to a ventilation device for a power pipe gallery cabin. Background Art

[0002] The power corridor cabin provides a safe and protected transmission channel for power cables, effectively isolating the cables from the external environment, thereby reducing the risk of cable damage due to bad weather, human damage, etc. By centrally managing power cables in the corridor cabin, the reliability and stability of power supply can be significantly improved. At the same time, the corridor cabin also reduces power loss, thus helping to save energy and reduce consumption.

[0003] There will be ventilation devices in the power corridor cabin, which can effectively remove the exhaust gas and waste heat in the power corridor cabin, maintain the suitability of the internal environment, and ensure that the power line equipment operates under normal temperature, humidity and air quality. In actual use, not all vents of the ventilation device are used at the same time. Unused vents form "dead zones" for air flow. These areas are prone to accumulate dust and pollutants due to the lack of flowing air. When these vents are used again, the accumulated dust and pollutants will be blown into the corridor cabin, affecting the air quality. Dust accumulation inside the ventilation device will also cause equipment failure or performance degradation. Utility Model Content

DETAILED DESCRIPTION

[0026] 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.

[0027] See also Figure 1-6 , a ventilation device for a power corridor cabin, comprising a ventilation duct 2, the ventilation duct 2 is installed on the inner top wall of the corridor cabin 1, the bottom of the ventilation duct 2 is equidistantly provided with ventilation holes, and the bottom of the ventilation holes is connected to a protective component 4;

[0028] The protective component 4 includes a storage box 401 and a positioning box 407. The storage box 401 is internally rotatably connected to a storage roller 402. The outer surface of the storage roller 402 is wound with a shielding cloth 404. One end of the shielding cloth 404 extends to the outside of the storage box 401. Both sides of one end of the shielding cloth 404 are fixedly connected to connecting plates 405. One end of the connecting plate 405 is fixedly connected to a sliding sleeve 406, and a locking piece is provided on the sliding sleeve 406. The covering of the shielding cloth 404 can effectively prevent dust and pollutants from invading the ventilation device, and when ventilation is not required or the ventilation volume needs to be reduced, some or all of the vents can be closed to reduce energy waste and improve energy utilization efficiency. By setting the protective component 4, the problem of unused vents being easily invaded by dust can be effectively solved, while the flexibility and maintenance convenience of the ventilation device are improved.

[0029] One end of the storage roller 402 penetrates and extends to the outside of the storage box 401, and one end of the storage roller 402 is fixedly connected to a turntable 403. The rotation of the storage roller 402 can be operated by the turntable 403, so as to control the unfolding and storage of the shielding cloth 404, thereby improving convenience.

[0030] The storage box 401 is provided with a straight groove, and the width of the shielding cloth 404 is smaller than the width of the straight groove, so that the shielding cloth 404 can be easily stored and unfolded inside the storage box 401 under the drive of the storage roller 402, ensuring the smoothness of the shielding cloth 404 during movement and avoiding stagnation or damage caused by excessive width.

[0031] A guide groove 409 is provided on the inner side of the storage box 401, and the connecting plate 405 is slidably connected in the guide groove 409. The guide groove 409 provides a stable moving track for the connecting plate 405, ensuring that the shielding cloth 404 can move smoothly during the unfolding and storage process without deviation or shaking, thereby improving the stability and accuracy of the operation.

[0032] The top of the storage box 401 is open, and a cover plate 410 is fixedly connected to the top of the storage box 401. A transverse groove is provided on the top of the cover plate 410. The locking member includes a threaded rod 411, the top of which passes through the transverse groove and extends to the top of the cover plate 410. A lock nut 412 is provided on the top thread sleeve of the threaded rod 411, and the bottom of the lock nut 412 abuts against the top of the cover plate 410. The threaded rod 411 passes through the transverse groove on the cover plate 410 and cooperates with the lock nut 412 to form a convenient locking mechanism. By rotating the lock nut 412, the position of the sliding sleeve 406 on the sliding rod 408 can be easily fixed or released, thereby realizing the control of the expansion or storage of the shielding cloth 404, and the opening degree of the vent can be flexibly adjusted as needed.

[0033] A wind direction adjusting member 3 is connected inside the vent. The wind direction adjusting member 3 is a rotatable blade, a shutter or other adjusting plate that can adjust the wind direction. The wind direction in the vent can be adjusted through the wind direction adjusting member 3.

[0034] The inner bottom wall of the gallery cabin 1 is fixedly connected with a base 5, and the top of the base 5 is fixedly connected with a power pipe 6. As an important channel for power supply, the power pipe 6 is fixed on the base 5 to ensure the stable transmission of power. The gallery cabin 1 provides a safe and protected transmission channel for the power cable, effectively isolating the cable from the external environment, thereby reducing the risk of damage to the cable due to bad weather, human damage and other factors.

[0035] Working principle: In normal use, the shielding cloth 404 is stored inside the storage box 401 through the rotation of the storage roller 402, and the vent is in an open state to allow air circulation;

[0036] When all the vents do not need to be used or dust intrusion needs to be prevented, the locking member is unlocked, and the sliding sleeve 406 slides along the sliding rod 408, driving the connecting plate 405 and the shielding cloth 404 to move, and the shielding cloth 404 gradually unfolds and covers the vents to close the vents. The covering of the shielding cloth 404 effectively prevents dust and pollutants from invading the ventilation device, and when ventilation is not needed or the ventilation volume needs to be reduced, some or all of the vents can be closed to reduce energy waste and improve energy efficiency. By setting the protective component 4, the problem of dust intrusion into unused vents can be effectively solved, while improving the flexibility and maintenance convenience of the ventilation device.
