When the crankcase body 10 is used, when an engine is placed at the inner end of the crankcase body 10, a large amount of heat energy is generated due to the operation of the engine, at the moment, the hydraulic rod 211 is opened, the hydraulic rod 211 drives the special-shaped plate 212 to slide along the inner end of the connecting groove 150, the special-shaped plate 212 drives the traction plate 213 and the connecting plate 214 to move horizontally, each rotating ring 221 is driven to rotate in the moving process of the traction plate 213, the rotating ring 221 drives the vane 222 to rotate, airflow is generated in the rotating process of the vane 222, each side ring 230 is driven to rotate by the connecting plate 214, the side rings 230 drive the vanes to rotate, airflow is generated in the rotating process of the vanes, and the air flow rate at the inner end and the outer end of the crankcase body 10 is accelerated through the airflow generated in the rotating process of the vane 222 and the vanes, therefore, heat energy generated at the inner end of the crankcase body 10 is timely discharged, meanwhile, the cleaning plate 224 is driven by the L-shaped sliding rod 227 to slide above the top screen plate 120 in the moving process of the special-shaped plate 212, the brush 2241 arranged at the bottom end of the cleaning plate 224 is in contact with the top end of the top screen plate 120, dust accumulated at the top end of the top screen plate 120 is cleaned, the special-shaped plate 212 drives the side plates 231 to slide along the side surfaces of the side screen plates 140, the brush rod at the bottom end of the side plate 231 is in contact with the side surfaces of the side screen plates 140, and the dust accumulated at the side surfaces of the side screen plates 140 is cleaned, so that the permeability of the top screen plate 120 and the side screen plates 140 is improved, and the influence of dust accumulation on the air exhaust effect of the top screen plate 120 and the side screen plates 140 is avoided.
A stopper 161 is slidably connected to an inner end of the slide groove 160, and a stopper spring 162 is connected between a side surface of the stopper 161 and the inner end of the slide groove 160. When the L-shaped sliding rod 227 slides along the inner end of the sliding groove 160, the L-shaped sliding rod 227 is easily contacted with the inner wall of the sliding groove 160, so that the two are mutually collided, the abrasion of the contact position is caused, the service life of the L-shaped sliding rod 227 is influenced in the long term, the position of the L-shaped sliding rod 227 is limited by the arranged stop block 161 at the moment, when the L-shaped sliding rod 227 slides along the inner end of the sliding groove 160, the stop block 161 is firstly contacted, the stop block 161 is driven to slide along the inner end of the sliding groove 160 together, the limit spring 162 is in a compression state at the moment, when the limit spring 162 is compressed to the maximum limit, the stop block 161 cannot continuously slide at the moment, the L-shaped sliding rod 227 cannot be contacted with the inner wall of the sliding groove 160, and the L-shaped sliding rod 227 is prevented from being collided with the inner wall of the sliding groove 160 through the elastic force of the limit spring 162 and the thrust of the L-shaped sliding rod 227.
Furthermore, both sides of the inner end of the sliding groove 160 are provided with limit grooves 170, the bottom ends of both sides of the L-shaped sliding rod 227 are provided with T-shaped sliding blocks 2271, and the T-shaped sliding blocks 2271 are slidably connected with the limit grooves 170. During the specific use, prescribe a limit to L type slide bar 227 sliding position through the spacing groove 170 that sets up, make L type slide bar 227 about both sides receive two spacing groove 170 centre grippings, L type slide bar 227 can't reciprocate, can only be along the inboard horizontal slip of spout 160, thereby improve L type slide bar 227 sliding stability, guarantee clearance board 224 and top net board 120 level keep balance, make brush 2241 can with top net board 120 top keep in touch, improve cleaning efficiency.
Still further, the bottom of cover disc 225 is seted up the cavity, and clearance board 224 top is connected with the cavity rotation. During the specific use, cleaning plate 224 slides the in-process along top otter board 120 top, produces frictional force between brush 2241 and the top of top otter board 120, and frictional force drives cleaning plate 224 and cover plate 225 and rotates, improves cleaning plate 224 clearance effect.
Specifically, the cleaning plate 224 is provided with a plurality of balls 2242 on the side, an inner groove 2252 is formed at the top of the inner end of the cover 225, and the balls 2242 are rotatably connected to the inner groove 2252. Because cleaning plate 224 and cover 225 rotate the in-process, contact position produces certain frictional force between the two, produces frictional force and can hinder cleaning plate 224 and rotate, converts sliding friction into rolling friction through the inside groove 2252 and the ball 2242 that set up this moment to the reduction is to cleaning plate 224's hindrance effect, improves cleaning plate 224 rotation performance, further improves cleaning plate 224's clearance effect.
In addition, both sides of the cover disc 225 are respectively connected with the two L-shaped sliding rods 227 in a rotating manner, a plurality of door shafts 2251 are arranged in the middle of the top end of the cover disc 225, and the cleaning plate 224 is composed of two plane plates which are respectively arranged on both sides of the bottom end of the cover disc 225. Door-hinge 2251 falls into two equal arc boards with cover plate 225, and two arc boards pass through the door-hinge 2251 and articulate each other for cover plate 225 both ends can freely be folded, overturn two plane boards, thereby can realize the free function of changing to brush 2241, improve brush 2241 duration, guarantee cleaning work normal operating.
Further, both sides of the bottom end of the cover plate 225 are provided with a side swing 226, and the bottom end of the side swing 226 is attached to the bottom end of the crankcase body 10. During specific use, lid dish 225 slides the in-process along top otter board 120 top, brush 2241 scrapes off the dust of the inner accumulated of top otter board 120, the dust of scraping off moves to the top groove 110 outside through brush 2241, when brush 2241 contacts top groove 110 border position, the dust of brush 2241 side adhesion receives top groove 110 border position very easily and blocks, lead to partly dust adhesion at top groove 110 border position, can carry out the secondary clearance to the dust of top groove 110 border position adhesion through the side pendulum 226 that sets up this moment, ball 2242 is behind top groove 110 border position, side pendulum 226 bottom can be through top groove 110 border position once more, carry out the secondary clearance to the dust that top groove 110 border position accumulated and save, further put forward high definition clearance effect.
Still further, the side swing 226 is a funnel-shaped structure, and the sectional dimension of the bottom end of the side swing 226 is larger than the sectional dimension of the top end of the side swing 226. When the dust-proof cover is used specifically, the contact area between the bottom end of the side swing 226 and the edge of the top groove 110 is increased, the cleaning range is further increased, and dust residues are avoided.
In addition, a leak 2331 is formed at the top end of the sector plate 223. The shielding range of the fan-shaped plate 223 is reduced by the arranged drain 2331, and the permeability of the fan-shaped plate 223 is increased, so that the speed of the airflow generated by the fan 222 flowing to the inner end of the crankcase body 10 is increased, the heat blocking effect exhausted from the inner end of the crankcase body 10 is reduced, and the free air exchange efficiency of the inner end and the outer end of the crankcase body 10 is ensured.
