The physical structure is used for replacing a detection signal, the function of door opening and power off is realized more effectively, and the safety and reliability of the equipment are greatly improved.
further, an elastic means is connected to a side of the load module 300 opposite to the access door 200. The elastic device is preferably a pressure spring 500, one end of the pressure spring 500 is fixed with the inside of the access door, and the other end of the pressure spring is abutted against one side face, opposite to the access door 200, of the load module 300.
Further, the power cutoff structure of the access door further includes a guide for guiding the movement of the load module 300 when the access door 200 is opened, changing the position of the load module 300. The guide 400 includes a guide groove in which the load module 300 is disposed, and when the access door is closed, the load module 300 abuts against the access door 200.
the power-off structure of the access door can be applied to different electrical structure products to realize the power-off function during maintenance. The invention takes a fresh air blower as an example, referring to fig. 1 and 2, the fresh air blower comprises a front door 100 and an access door 200, and the access door 200 is opened when being used for later maintenance and is usually arranged on the side surface of a fresh air cabinet. The new blower in this embodiment includes a power-off structure of an access door, and the load module 300 includes a plurality of filter modules 310 of the new blower. The filter modules 310 of the fresh air machines are connected with elastic devices. When the access door 200 is opened, the elastic means can move the plurality of filter modules 310 along the guide means 400, thereby disconnecting the circuit connection between the filter modules 310 and the new fan. The filtering module 310 is in a power-off state at this time, so that the worker can take out the filtering module 310 without danger, and the safety of people is greatly ensured.
Further, the guide 400 includes a plurality of guide grooves. The filter modules 310 are respectively disposed in each guide groove, and each filter module 310 abuts against the inner side surface of the access door 200. As shown in fig. 3, specifically, the guide groove is composed of a bottom plate 410 and two side plates 420, in one embodiment, two side plates 420 are provided, one filter module 310 is inserted between the two side plates 420, and one filter module 310 is inserted between each of the two side plates 420 and the inner side wall of the fresh air cabinet. It will be appreciated that depending on the number of filter modules 310, a corresponding number of side panels 420 may be provided for receiving the filter modules 310.
further, an elastic means is coupled to a side of the filter module 310 opposite to the access door 200. The elastic device can be a spring, an elastic sheet and other elastic pieces. As shown in fig. 3, the elastic device is preferably a compression spring 500, one end of the compression spring 500 is fixed to the inner wall of the housing, and the other end of the compression spring abuts against one side surface of the filter module 310 opposite to the access door 200. The compression spring 500 preferably abuts against the middle of the filter module 310 to ensure smooth sliding of the filter module 310. When the access door 200 is opened, the filtering module 310 slides outwards along the guide groove by the elastic force of the pressure spring 500.
as shown in fig. 4, each filter module 310 is further provided with a first contact piece 311, and as shown in fig. 3, the guide 400 is correspondingly provided with a second contact piece 430 capable of contacting with the first contact piece 311. The first contact pad 311 and the second contact pad 430 are both of a metallic conductive material, preferably copper or a phosphor bronze alloy. When the new fan works, the first contact piece 311 is in contact with the second contact piece 430 for conduction, the circuit between the filtering module 310 and the new fan is normally conducted, and the filtering module 310 normally works. When needing to overhaul, the access door 200 is opened, and the filter module 310 outwards slides out along the guide slot, and the first contact piece 311 on the filter module 310 misplaces with the second contact piece 430 on the guide slot, and the circuit between first contact piece 311 and the second contact piece 430 is disconnected, and then the circuit connection between the filter module 310 and the new fan has been disconnected.
Further, the first contact piece 311 is disposed at the bottom of the filter module 310 and embedded in the bottom surface of the filter module 310. Accordingly, the second contact piece 430 is disposed in the guide groove and embedded on the bottom plate 410, and is opposite to the first contact piece 311 when the filter module 310 is in normal operation.
Specifically, each filter module 310 is provided with two pieces of first contact pieces 311, and accordingly, the guide 400 is provided with the same number of second contact pieces 430 as the first contact pieces 311. In the present embodiment, three filter modules 310 are provided, and it is understood that the filter modules 310 are provided appropriately according to the specification and size of the fresh air machine.
further, the guide 400 guides the movement direction of the filter module 310 to be perpendicular to the access door 200. The side plate 420 is perpendicular to the access door 200 so that the access door 200 is opened from either side and the filter module 310 is easily slid along the guide groove and taken out. Meanwhile, the elasticity of the pressure spring 500 is ensured to vertically act on the filter module 310, so that the filter module is easy to push to move.
In other embodiments, the guide 400 may be disposed on the bottom side of the interior of the fresh air machine, or may be disposed on the top side of the interior of the fresh air machine, but is preferably disposed on the bottom side for ease of installation.
The working process of the power-off structure of the fresh air machine access door is as follows:
When the fresh air fan normally works, as shown in fig. 5, the compression spring 500 is connected with the filtering module 310, the filtering module 310 abuts against the inner side of the access door 200, at this time, the first contact piece 311 at the bottom of the filtering module 310 contacts and is conducted with the second contact piece 430 on the bottom plate 410, and the filtering module 310 is electrified and normally works.
When the access door 200 needs to be maintained and opened, as shown in fig. 6, the filter module 310 moves towards one side of the access door 200 under the action of the elastic force of the pressure spring 500, the first contact piece 311 and the second contact piece 430 at the bottom of the filter module 310 are staggered, the circuit is disconnected, the power is cut off in the filter module 310, and the filter module 310 can be taken out at this time.
Adopt the new fan of the outage structure of above-mentioned new fan access door, use guider and resilient means's physical structure, realized opening the door the function of outage effectively, improved the fail safe nature of new fan greatly.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
