Embodiment 1
[0022] refer to Figure 1-8 , a lithium battery case for a communication base station, comprising a first box body 1, a dodge door 22 is hingedly mounted on the first box body 1, and two corresponding supporting legs are fixedly installed on the lower part of the outer wall of the first box body 1 23. The top of the first box body 1 is fixedly installed with the second box body 2 communicating with it inside, a filter grid 3 is arranged between the first box body 1 and the second box body 2, and the top surface of the second box body 2 is fixed A cylinder 4 communicating with it is installed inside, and a first rotating shaft 5 coaxially arranged with it is rotatably installed in the cylinder 4, and a fan blade 6 is fixedly installed on the top of the first rotating shaft 5, and on the outer wall of the first box body 1 A fixed plate 11 is fixedly installed, and a third rotating shaft 12 parallel to the first rotating shaft 5 is rotatably installed on the fixing plate 11. The ...
Embodiment 2
[0028] refer to Figure 1-8 , as another preferred embodiment of the present invention, the difference from Embodiment 1 is that a scraper 21 corresponding to the movement track of the brush 17 is provided on one side of the filter screen 18, and the scraper 21 is fixedly installed on the first box 2 On the bottom surface, the scraper 21 is formed by a number of triangular prisms arranged at equal intervals, and the triangular prisms are all set towards the side away from the second rotating shaft 12 .
[0029] When the crank-link mechanism drives the brush 17 to reciprocate in a straight line along the guide rod 19, when the brush 17 passes the scraper 21, the triangular prism on the scraper 21 will scrape off the impurities attached to the bristles of the brush 17, In this way, it is avoided that too many impurities are attached to the brush 17 and the cleaning effect is deteriorated.
