Specific implementation mode
By reference to exemplary embodiment, the purpose of this utility model and function and for realizing these purposes and function
Method will be illustrated.However, the utility model is not limited to exemplary embodiment as disclosed below；It can be by not
It is realized with form.The essence of specification is only to aid in various equivalent modifications Integrated Understanding the utility model
Detail.
Hereinafter, the embodiments of the present invention will be described with reference to the drawings.In the accompanying drawings, identical reference numeral represents
Same or similar component or same or like step.
Lifting gear in the utility model mainly utilizes cam mechanism when cover board drainage situation is bad by it
Certain distance is jacked, draining is promoted.
As Figure 1-Figure 4, the lifting gear of the drainage ditch cover plate in the utility model, the lifting gear are mounted on draining
The lower section of trench cover 4, the lifting gear may include header tank 1, multiple (at least two) cams 2 and multiple (at least two) connecting rods
3 etc..
The upper end opening of header tank 1, the receiving portion 11 at middle part can be ponding portion 11, (a) and (b) institute in position such as Fig. 4
Show.Cam 2 is set between drainage ditch cover plate 4 and header tank 1, is connect with header tank 1 by connecting rod 3.Cam may include round wheel part
21 and protrusion 22, cam 2 can be fixed on the gutter side wall of 4 lower section of drainage ditch cover plate by passing through the shaft of portion's through-hole
On.Cam 2 can surround shaft and rotate, but cannot slide axially along shaft.One end of connecting rod 3 is connected to the eccentric position of cam 2,

Multiple positions set on 1 side of header tank are preferably symmetrical arranged or are uniformly arranged along header tank side.Header tank 1 accumulates
Lower water when reaching preset water, since gravity increases, the position of header tank 1 declines, and is rotated with moving cam 2 by connecting rod 3,
The protrusion 22 of cam 2 jacks the cover board 4 in gutter.One side in the present invention, cam 2 may be similar to convex
Other modified constructions of wheel ensure that the construction of protrusion can jack cover board.
Preferably, the lower wall of header tank 1 and/or side wall are equipped with osculum 12.The arrangement of 12 quantity of osculum and size is answered
Consider the lower water speed with cover board 4, should ensure that, in 4 larger displacement of cover board, the drainage speed of the osculum 12 of header tank 1 is small
In undertaking speed so that ponding portion 11 has ponding, and when water accumulating volume is more than a certain amount of, since weight increases, header tank 1 declines,
It is rotated with moving cam 2 by connecting rod 3.
When road surface water is less, to make the cover board in gutter decline, lifting gear is also provided with cam return mechanism,
Including shaft 8, bearing assembly 7, torsional spring 6 etc..Cam 2 is installed in one end of shaft 8, and cam 2 and shaft 8 can be keyed, cam 2
Mounting hole be preferentially opened in round wheel part.Bearing assembly 7 is installed on the other end of shaft 8, can contain bearing, fixed structure etc.,
Bearing assembly 7 can be fixed on by fixed structure on the side wall in gutter.Torsional spring 6 is resisted against between cam 2 and bearing assembly 7,
And be sleeved in shaft 7, the both ends of torsional spring 6 are fixed respectively or are connected to cam 2, bearing assembly 7, as shown in figure 3, the one of torsional spring 6
End is stuck in the fixed structure 71 of bearing assembly 7, and the other end of torsional spring 6 is stuck in the fixed structure 24 of cam 2.Torsional spring 6 initially can be with
There is certain pretightning force, when cam 2 turns to jacking position, the torque of torsional spring 6 increases.When the lower water of cover board is less, collection
11 ponding of ponding portion of water tank reduces or emptying, and the torsional spring 6 of distortion generates rotary force, and cam 2 is promoted to return back to initial position,
Cover board 4 also drops to initial position due to own wt.Lifting gear through the above way, can be according to the lower water of cover board 4
It determines the jacking of cover board 4 or returns to initial position, convenient for adjusting the lower water speed of cover board 4.
Preferably, one end of connecting rod 3 is hinged with header tank 1, and the other end is hinged with cam 2, facilitates the swing of connecting rod 3.It is convex
Wheel 2 and connecting rod 3 can be equipped with two groups or more multigroup, uniformly and/or are arranged symmetrically between cover board 4 and header tank 1, such as Fig. 1, figure
Shown in 2, cam 2 and connecting rod 3 are equipped with two groups, and the both sides along 4 lower section of cover board are symmetrical arranged.As shown in figure 4, the ponding of header tank 1
Portion 11 also can be used as rubbish storage portion 11, and for accepting the rubbish to fall through cover board, the connection of header tank 1 and connecting rod 3 is side
Just the structure dismantled convenient for periodic cleaning rubbish or replaces header tank 1.
The utility model also provides a kind of cover board suitable for above-mentioned lifting gear, as shown in figure 5, being provided with water-filtering net
The position of hole, the lower part of cover board 4 and cam contact is provided with limiting slot 42, shown in (b) of position such as Fig. 5 so that cam will not turn
Partially.The seamed edge on 4 top of cover board is provided with chamfering 41, shown in (a) of position such as Fig. 5, when pedestrian or vehicle are contacted with cover board 4, increases
Big forced area ensures safety, when pedestrian or vehicle roll cover board 4, presses to cam, cam is promoted to rotate.It is preferred that
Ground, the edge or bottom of cover board 4 are equipped with position-limit mechanism, cover board are prevented to be detached from the position in gutter 5, and position is as shown in fig. 1.
Position-limit mechanism can be the edge for pulling the bottom of cover board 4, or blocking cover board 4.The cover board of aforesaid way is suitable for this reality
With the lifting gear in novel.
According to the cover board and its lifting gear in gutter provided by the utility model, obtainable advantageous effect at least exists
In：
1. the lifting gear in the utility model can be larger in lower water according to the lower water automatic lifting cover board of cover board
When, cover board jacking, top and surrounding can descend water, and road surface is promoted to accelerate draining, ensure that more ponding is not present in road surface.
2. cover board band can be back to initial position by the lifting gear in the utility model according to the lower water of cover board, ensure road
Face is smooth.
3. the header tank in the utility model can also be used for accepting the rubbish through cover board, prevent from blocking sewer or draining
Ditch.
