Description
Technical field
This utility model relates to a kind of trash rack being applied to middle and small river waterfall water harnessing project.
Background technology
In In Middle And Lower Reaches of Changjiang River, river course gather, the network of rivers in length and breadth, water plant spread unchecked growth, usually give river
Road flood passage, hydroelectric generation, ship navigation lamp bring obstacle, miscellaneous for blocking water plant, floating garbage etc.
Thing, in prior art, has a kind of trash rack, and its water surface in river course is fixedly installed fence, is blocked by fence
Resistance floater, is then passed through artificially collecting, clearing up, and reaches impurity removing, the purpose in cleaning river course.But
It is that this way also brings along drawback, when upland water amount is big, when needing big flow flood passage, substantial amounts of floating
At the fence that thing but stops, the speed of labor cleaning is relatively slow, can not meet the requirement of flood passage, thus causes flood passage
The most smooth；Substantial amounts of floating thing is collected at fence, under waterpower promotes, forms huge thrust, produces fence
Raw powerful thrust, can directly destroy by rush of water time serious fence, bringing on a disaster property consequence.
On the other hand, traditional trash rack is heavier and crossbeam is easily deformed more having very under the impact of weight
Person is ruptured, grizzly bar and grid body frame welding one, uses middle grizzly bar can be deformed by heavy impact, and impact is blocked
Dirty effect, is difficult to during maintenance change.
Utility model content
For the deficiencies in the prior art, the purpose of this utility model aims to provide one and is applied to middle and small river waterfall
The trash rack of water harnessing engineering, it can make fence switch with the needs blocking dirt or flood passage, can effectively block
Dirt, does not the most affect navigation and flood passage, facilitates grizzly bar to be replaced when being damaged by heavy impact simultaneously.
For achieving the above object, this utility model adopts the following technical scheme that one is applied to middle and small river waterfall water
The trash rack of harnessing project, including the fence being across on the river course water surface, described fence and some edges are vertically to river
The pillar that water surface direction, road is arranged connects, and the lower end of described pillar is across the rotating shaft of bottom of river channel setting even with one
Connecing, described bottom of river channel is provided with some mounting seats, described rotating shaft and described peace along the length direction of described rotating shaft
Dress seat is rotationally connected, and the one or both sides in river course are provided with the power house being isolated with river course, are provided with in power house
Rotary drive mechanism, the end of described rotating shaft stretches into and is connected with rotary drive mechanism in power house, described fence by
Frame, it is arranged in frame the some installation axles being flexibly connected with frame and level is sheathed on the grid on installation axle
Bar forms.
Preferably, the upper and lower side of described frame is arranged with some installation axis holes.
Preferably, described frame left and right side is arranged with some grizzly bar installing holes.
Preferably, described frame is rectangle.
Preferably, described rotary drive mechanism includes that the support seat being fixed in power house is articulated and connected with supporting seat
Hydraulic jack, the piston rod external part of described hydraulic jack is hinged with one end of connecting rod, described connecting rod another
The end of one end and described rotating shaft is fixed.
Preferably, the middle part of described grizzly bar is provided with for being sheathed on the circular hole on described installation axle.
The beneficial effects of the utility model are:
(1) this utility model can drive shaft be rotated by rotary drive mechanism, and rotating shaft drives fence to make through pillar
Rotary motion, when fence erects, can block on river course, it is achieved block dirt；When fence fell, river course can be direct
Flood passage, excessively ship, can effectively block dirt, does not the most affect navigation and flood passage.
(2) this utility model wears lath on the mounting shaft, can be replaced lath owing to extracting installation axle out,
Its safeguard, clean and change the most simple and convenient.
Accompanying drawing explanation
Fig. 1 is this utility model embodiment one structural representation.
Reference: river course 1；Fence 2；Pillar 3；Rotating shaft 4；Mounting seat 5；Support seat 6；Hydraulic jack
7；Frame 8；Axle 9 is installed；Grizzly bar 10.
Detailed description of the invention
Below, in conjunction with accompanying drawing and detailed description of the invention, this utility model is described further:
Embodiment one:
As it is shown in figure 1, a kind of trash rack being applied to middle and small river waterfall water harnessing project, including being across river
Fence 2 on road 1 water surface, described fence is vertically to the pillar 3 of water surface direction, river course setting and is connected with some edges,
The lower end of described pillar is across the rotating shaft 4 of bottom of river channel setting and is connected with one, and described bottom of river channel is along described turn
The length direction of axle is provided with some mounting seats 5, and described rotating shaft is rotationally connected with described mounting seat, the one of river course
Side or both sides are provided with the power house being isolated with river course, are provided with rotary drive mechanism, described rotating shaft in power house
End stretch into and be connected with rotary drive mechanism in power house.
Preferably, rotary drive mechanism described in the present embodiment include the support seat 6 that is fixed in power house and
Supporting the hydraulic jack 7 that seat is articulated and connected, the piston rod external part of described hydraulic jack cuts with scissors mutually with one end of connecting rod
Connecing, the end of the other end of described connecting rod and described rotating shaft is fixed.
By above-mentioned setting, rotary drive mechanism can drive shaft rotate, and rotating shaft drives fence to rotate through pillar
Motion, when fence erects, can block on river course, it is achieved block dirt；When fence fell, river course can directly flood passage,
Cross ship.This device, also by the adjustment of axis of rotation angle, makes fence suitably be obliquely installed, when blocking dirt,
The piling height of the floating thing being deposited in fence upstream side is adjustable, in order to according to the drift of entrained with in the current of upstream
The amount of float determines more reasonably labor cleaning's interval time.
In order to preferably clear up and keep in repair fence, described fence by frame 8, be arranged in frame with frame activity even
The some installation axles 9 connect and level are sheathed on the grizzly bar 10 installed on axle and form.Preferably, described frame
