Detailed Description
In order that those skilled in the art will better understand the technical solutions of the present invention, the following description of the preferred embodiments of the present invention is provided in conjunction with specific examples, but it should be understood that the drawings are for illustrative purposes only and should not be construed as limiting the patent; for the purpose of better illustrating the embodiments, certain features of the drawings may be omitted, enlarged or reduced, and do not represent the size of an actual product; it will be understood by those skilled in the art that certain well-known structures in the drawings and descriptions thereof may be omitted. The positional relationships depicted in the drawings are for illustrative purposes only and are not to be construed as limiting the present patent.
The utility model is further illustrated by the following figures and examples, which are not to be construed as limiting the utility model.
As shown in figures 1 to 2, a box culvert inspection shaft ventilation unit, including covering establish at the apron 2 at box culvert inspection shaft top, 2 middle parts of apron set up grid 7, still have the supporting role of grid 7 when guaranteeing the circulation of air, 2 sub-unit connection frames 9 of apron set up fan 4 in the frame 9, frame 9 and fan all set up in well 6, the sub-unit connection tuber pipe 5 of frame 9, 2's diameter size of apron is greater than well 6's diameter size, sets up between the position that 2 bottom surfaces of apron and ground contacted and aerifys cushion 3.
The lifting lugs 1 are symmetrically arranged on two sides of the top of the cover plate 2. The lifting lug and the cover plate are integrally manufactured and are used for lifting the cover plate.
The lower part of the cover plate 2 is provided with the inflatable rubber cushion 3 around the outer side of the shaft opening, and the inflatable rubber cushion 3 can compact the gap between the cover plate 2 and the ground after being inflated.
