The invention has the beneficial effects of big area of drain grating of single device and strong trash cleaning capability, is suitable for water inlet drain grating of large-scale hydraulic engineering with a wide water inlet, and has trash cleaning effect and efficiency which are both superior to the trash cleaning effect and efficiency of each kind of scraper pan type trash cleaning device.
Description
Technical field
The invention belongs to Hydraulic and Hydro-Power Engineering equipment,, be specially a kind of conjoined rotary type trash cleaning device for Hydraulic and Hydro-Power Engineering water inlet floating thing drags for equipment clearly.
Background technology
Rotary type trash cleaning device is that Hydraulic and Hydro-Power Engineering is used for many years, and progressively obtains expanding wide a kind of trash rake form.The major technique structure is seen CN 200520139582.8 and the accessible rotary type trash cleaning device of CN02255239.1.But,, never on the large-scale hydroelectric project project, use owing to reasons such as its structural strengths.Water inlet condition in the large-scale hydroelectric project: width 6-12 rice, head difference are greater than 4 meters, and flow velocity blocks the dirty degree of depth greater than more than 18 meters greater than 3 meter per seconds, as occasions such as great rivers main generator group water inlet such as the Changjiang river, the Yellow River.
Summary of the invention
The purpose of this invention is to overcome the defective that existing rotary type trash cleaning device can not be installed and used under these conditions, in conjunction with the large-scale hydroelectric project trashrack, design a kind of wide hole conjoined rotary type trash cleaning device, to be applicable to above-mentioned water inlet condition, for the large-scale hydroelectric project problem of removing contamination is overcome difficulties.
Design scheme of the present invention: conjoined rotary type trash cleaning device, comprise grid body, Rack rake system, support installing rack, the grid body is made up of vertical grizzly bar and crossbeam and is connected as one with the support installing rack, the Rack rake system is that electric power drives, and by level be installed in the supporting shaft at grid body top and top sprocket wheel thereof drive the running roller chain drive around the rotating tooth harrow group of grid body, on same set of grid body horizontal direction, be set up in parallel at least two cover Rack rake systems.
Generally speaking, the Rack rake system that is set up in parallel two cover symmetries on same set of grid body horizontal direction gets final product, there is a sprocket wheel at the supporting shaft two ends of every cover Rack rake system, hang with a pair of vertically parallel chain track on two sprocket wheels and around the rotating running roller chain of grid body, the tooth harrow of at least one group of level is housed between two running roller chains, tooth harrow is fixed on the tooth harrow crossbeam by one group of rake teeth, fixedlys connected with the running roller chain in tooth harrow crossbeam two ends; Two overlap the tooth rake system that removes contamination respectively has a cover electric power to drive, and symmetry is respectively in both sides, the top inner chambers of grid body, and gives supporting shaft by the power output sprocket and the chain that extend in the outside, grid body both sides with transmission of power.
Be to increase the security reliability of transmission of power, can described power output sprocket and chain be set to two-row structure.
Consider that this device underwater portion is subjected to hydraulic pressure and water flow impact pressure, the grid body desired strength height of underwater portion, crossbeam should strengthen design strength, but above water is structure needs such as support chain wheel chain, so above-mentioned grid body designs for variable cross-section, the work thickness of the following part of the water surface of thickness of the above part of its work water surface of removing contamination is little, and towards last arc-shaped transition indentation, sectional area diminishes from working water at the grid body back side.The installing space on the service bridge can be saved so on the one hand, also manufacturing cost can be reduced.
Rake teeth on the described tooth harrow group is the two rake teeths of taper, impacts to adapt to the big dirt of weight.
The good effect that the present invention produced: compare with existing rotary type trash cleaning device, it is big that unit blocks dirty area, decontamination amount is big, clean-up capability is strong. can be fit to water inlet width 6-12 rice, head difference is greater than 4 meters, flow velocity is greater than 3 meter per seconds, blocking the dirty degree of depth and block dirt greater than the large hydropower station water inlet more than 18 meters. this has expanded the scope of application of rotary type trash cleaning device greatly, break rotary type trash cleaning device under deep water top news part, the history that can not use. not only can in large water conservancy hydroelectric engineering, use, and remove contamination effect and efficient are better than all kinds of slusher formula trash rakees. advantage is as follows particularly:
1) with the problem of the removing contamination simple process of large-scale power station water inlet complexity, can use the design's rotary type trash cleaning device, the trashrack body can require design according to the aperture, and is unaffected.
2) overcome trashrack of traditional rotary type trash cleaning device corresponding and overlap the constraint of turning round the system that removes contamination around grid, be set up in parallel the Rack rake system of two cover symmetries on an expanded letter trashrack, system's synchronous working but two covers are removed contamination also can work independently.
3) non-uniform beam grid body is handled, and has solved the conjoined rotary type trash cleaning device economy problems, and the water surface owing to there is not water pressure requirement, the girder minimizing cost that diminishes, also can be saved the installing space on the service bridge with upper part, provides convenience for dirt conveying equipment etc. is installed.
4) remove contamination rake teeth design of taper solves the medium-and-large-sized floating thing bump of great rivers back rake teeth problem on deformation, makes the conjoined rotary type trash cleaning device operation more reliable.
