Any of bar, atmospheric pressure pole and electric pushrod, it is preferable that use electric pushrod.
As shown in Figure 3 and Figure 4, in 1 uphill process of cover board body, electric pushrod stretches out upwards, and passes through cover board body 1
Support column synchronization lifting is driven, (support column stretches out the height of melt pit at this time when support column slides into the end of 21 upper end of sliding rail
Not less than the height of ground absorbing material layer), as shown in Figure 5 and Figure 6, electric pushrod continues to rise, due to support column and cover board
It is rotatablely connected between ontology 1, the upper end of electric pushrod is also rotatablely connected with cover board body 1, and cover board body 1 is around for connecting support
The shaft of column and cover board body 1 rotates, and realizes the overturning of cover board body 1.
Preferably, the interval of sliding rail 21 of two the first telescoping mechanisms 2 is fixed on a side wall of melt pit 10, and second is flexible
The side wall that mechanism was fixed on and was fixed with sliding rail 21 has the melt pit bottom of certain distance.
When the first telescoping mechanism 2 is using without from the telescoping mechanism of power-assisted, and two telescoping mechanisms pass through shaft and cover board
Ontology 1 connect when, 1 relative telescopic mechanism of cover board body has certain decline freedom degree, will lead to sliding rail 21 have it is certain under
Sliding, support column is along sliding rail slide downward in order to prevent, in some preferred embodiments, as shown in fig. 7, on the side wall of melt pit 10
Or block 4 is arranged in the upper end of sliding rail 21, the plectrum 5 that setting can be moved and be overturn with cover board body 1 on cover board body 1,
Rotatable clutch-plate 6 is set on cover board body 1 or support column, and in the switching process of cover board body 1, plectrum 5 is gradually
It is against the upper end of clutch-plate 6, pushes clutch-plate 6 to rotate around the axis, is against the free end of clutch-plate 6 on block 4, at this point, dialling
Stable support construction is formed between piece 5, clutch-plate 6 and block 4, prevents support column along sliding rail slide downward.Simultaneously in cover board
When ontology 1 turns round, clutch-plate 6 supports cover board body 1, and cover board body is made not glide being turned back to horizontality forward support post,
The support column just decline synchronous with the pars contractilis of the second telescoping mechanism when not being turned back to horizontality of cover board body 1 is avoided, from
And avoid cover board absorbing material layer 9 from interfering with neighbouring 7 layers of ground absorbing material, when cover board body 1 be turned back to it is horizontal
When state, plectrum 5 pushes clutch-plate 6 to leave block 4 completely, makes cover board body 1 that horizontality be kept to drop to cover board body 1 complete
It closes.
Preferably, clutch-plate 6 is spindle rotationally arranged on cover board body 1 or on support column by third shaft.
In some preferred embodiments, as shown in Figure 7 and Figure 8, the front end of plectrum 5 is equipped with spaced first support
51 and second support 52, and the length that forward extends out of the first support 51 is less than the length that the second support 52 forward extends out, and
Two supports 52 are located at the upside of the first support 51, and during opening cover board body 1, the second support 52 turns over clutch-plate 6, not with
Clutch-plate 6 contacts, and the first support 51 pushes the free end (lower end) of clutch-plate 6 to be against on block 4, and is closing cover board body 1
In the process, the first support 51 progressively disengages clutch-plate, and the second support 52 is gradually against on clutch-plate 6, push clutch-plate gradually from
Block 4 is opened, when cover board body 1 is when being turned back to horizontality, clutch-plate 6 completely disengages block 4, and cover board body 1 is made to keep water
Level state decline, until completely closing.
In the present embodiment, as shown in Figure 7 and Figure 8, plectrum 5 and block 4 are respectively positioned on the side of clutch-plate 6, clutch-plate 6
Upper end is equipped with the screw stretched out to side, and for cooperating with plectrum, lower end also is provided with the screw stretched out to side, uses
Cooperate in block 4.
In some preferred embodiments, as shown in Figure 5-Figure 7, one is equipped in 22 upper end of pars contractilis of the first telescoping mechanism
A support platform 23, in cover board body 1 in horizontality, support platform 23 can with the downside face contact of cover board body 1, it is right
Cover board body 1 plays certain supporting role, is rotatablely connected in the first telescoping mechanism 2 and the second telescoping mechanism 3 with cover board body 1
In the case where, additionally it is possible to play the role of preventing cover board body 1 from shaking.
