When in use, the two fans 6 are switched under the closed state through the structures of the guide post 303, the slide block 505 and the like, and the working process and the effect of the part are the same as those of the first embodiment, and the repeated description is omitted. The difference is that: when the baffle 501 moves along the groove 403, the lateral plate 506 is driven to move synchronously by the transverse plate 507 and the long hole 405, and the baffle 501 and the lateral plate 506 are relatively close to each other through the side holes 502 when moving, so that avoidance is formed for the baffle 501 and the lateral plate 506, and the baffle 501 and the lateral plate 506 can block the combustion-supporting air pipes 101/the hydrogen pipes 102 on two sides of the fan 6. When the baffle 501 is reset along the groove 403, the lateral plate 506 can be driven to move synchronously by the transverse plate 507, so as to release the sealing of all the combustion-supporting air pipes 101/hydrogen pipes 102.
In the first embodiment, although the combustion-supporting air pipe 101/hydrogen pipe 102 on one side of the fan 6 can be closed to avoid the influence of gas leakage on the whole use, the combustion-supporting air pipe 101/hydrogen pipe 102 on the other side of the fan 6 is in an open state, so that the gas in the combustion-supporting air pipe 101/hydrogen pipe 102 on the side can escape, thus the working resources are wasted to a certain extent, and certain use limitations exist.
Compared with the first embodiment, through the cooperation of structures such as the side plate 506, the transverse plate 507, the baffle 501 and the long hole 405, the baffle 501 can drive the side plate 506 to move when moving, and forms complete sealing for the combustion-supporting air pipes 101/the hydrogen pipes 102 on two sides of the fan 6, thereby completely avoiding gas leakage and further ensuring the complete utilization of resources. The whole scheme combines with the removal of baffle 501, and can not influence the removal of baffle 401, and the result of use is better, and the suitability is stronger.
As a further improvement of the present embodiment: as shown in fig. 10, based on the design of the sleeve 701 and the expansion ring 702, the outer surface of the sleeve 701 is slidably matched with the insert plate 703 movably attached to the fan 6, a certain friction force exists between the insert plate 703 and the sleeve 701, the surface of the insert plate 703 close to the fan 6 is arranged to be a wedge surface, the insert plate 703 on the sleeve 701 of the lower fan 6 is positioned at the lower side, and the insert plate 703 on the sleeve 701 of the fan 6 of the construction side is positioned at the upper side. When the two fans 6 are in the lowered state, the insert plate 703 of the lower sleeve 701 contacts with the inner bottom wall of the casing 2 so that the insert plate 703 automatically rises, and when the two fans 6 are in the raised state, the insert plate 703 of the upper sleeve 701 contacts with the inner top wall of the casing 2 so that the insert plate 703 automatically descends.
Alternatively, the fan 6 is disposed at a position of the sleeve 701 near the opening 201, or the fan 6 extends out of the sleeve 701 relatively to be in position corresponding to the telescopic ring 702, and a spring (not shown in the figure) is fixedly installed between the inner wall of the sleeve 701 and the fan 6, and the spring can limit the fan 6 to a position of the sleeve 701 near the opening 201, so that the fan 6 can be relatively near the opening 201 under the action of the spring after the baffle 501/side plate 506 is removed.
Through the design, when two fans 6 are in a descending state, the fans 6 corresponding to the lower opening 201 translate towards the wind direction of the opening 201, and at the moment, the fans 6 can be closer to the opening 201, so that the two fans 6 are further convenient for workers to take and place in place, and the same is true when the two fans 6 are in an ascending state.
