Description
Technical field
The invention belongs to power station technical field of waste treatment, be specifically related to the movable sewage blocking device of a kind of intercepted garbage on water being arranged at intake of hydropower station.
Background technology
Water-power plant, is the integration engineering facility that water can be converted to electric energy, generally comprises the reservoir formed by dash, outlet structure escape works and Diversion system of hydropower station, power plant building, electromechanical equipment etc..Generally, the check dam of medium and small water-power plant is built because of physical features, because water channel is narrower, bigger by natural environment influence, the dirt of water float, foreign material, such as branch, leaves, weeds, or even house refuse usually threatens the normal operation of generating set, for this reason, it may be necessary to arrange sewage blocking device before intake.
The sewage blocking device of prior art mostly adopts cable wire connect flotation tank and block the mode of dirty grid.As Chinese patent (CN105200966A) discloses the sewage collection system of water inlet upstream, a kind of power station, garbage on water is classified interception and collects to adopt three layers dirt collection net to guarantee, simple in construction, it is prone to use, cheap, but owing to this dirt collection net can not realize being freely lifted, it is impossible to ensure that dirt collection net is in the best dirt collection position along with SEA LEVEL VARIATION.Chinese patent (CN204589957U) discloses a kind of trash rack hurdle, power station, the height of crane is regulated, it is achieved garbage barrier net is suitable for water level raising and lowering by motor, but owing to this garbage barrier net adopts integrated design, when garbage barrier net somewhere is damaged can only integral replacing, maintenance cost is high.Chinese patent (CN201671087U) discloses a kind of automatic lifting water channel and efficiently blocks dirty drainage device, coordinated with lifting guiding assemblage by I-shaped structure directing post, achieve along with SEA LEVEL VARIATION is steadily freely lifted, cut dirt net and adopt modular construction, linked by hinge between adjacent cells and connect, easy maintenance and replacement.But above sewage blocking device, along with increasing of garbage barrier net catching rubbish thing, if cleaning can result in blockage not in time, hinders current, even can press and block dirty net, cause heavy losses.
Summary of the invention
For the deficiencies in the prior art, the invention provides the movable sewage blocking device of a kind of intercepted garbage on water being arranged at intake of hydropower station, this device can freely regulate the height of trash rack according to SEA LEVEL VARIATION, trash rack adopts modular construction, easy maintenance and replacement, and can sense and detect the quantity of trash rack catching rubbish thing in real time, in order to clear up in time, solve the problem needing manual site to detect, time saving and energy saving.
Concrete, the movable sewage blocking device of intake of hydropower station of the present invention, including left column, right column, and it is connected to the trash rack support bar between described left column, right column, trash rack, wherein, described trash rack adopts modular construction, and each trash rack is blocked dirty support by garbage barrier net, " returning " type, snap fit forms, described garbage barrier net is fixedly connected on " returning " type and blocks in dirty the inside casing being configured to, and snap fit is fixedly connected on " returning " type and blocks on dirty support；Described trash rack support bar is provided with the draw-in groove matched with snap fit.
Trash rack adopts modular construction, and each trash rack back side is provided with snap fit, can directly be buckled on the draw-in groove of trash rack support bar, be easy for installation and removal, and then easy maintenance and replacement.
Further illustrating as the present invention, described " time " type blocks dirty support and is provided with a pair symmetrical snap fit, and snap fit is provided with snap fit fixing hole, described snap fit fixing hole and trash rack support bar is arranged at the support bar fixing hole below draw-in groove and matches.
The setting of snap fit fixing hole and support bar fixing hole, makes trash rack be fixed on trash rack support bar better in combinations with screw nut element, it is to avoid because being come off by excessive rubbish thrust.
Further illustrating as the present invention, the junction of described trash rack support bar and left column, right column is provided with pressure transducer, and described pressure transducer is connected with sender unit.
Further illustrating as the present invention, also includes monitoring camera-shooting instrument, described in include monitoring camera-shooting instrument and be connected with sender unit.
Pressure transducer can experience the rubbish thrust that trash rack support bar is subject to, monitoring camera-shooting instrument Observable sewage blocking device retains the information of rubbish, and then by sender unit by thrust data and situation image transmitting to monitoring personnel, in order to monitoring personnel immediately control sewage blocking device and retain the situation of rubbish.
Further illustrating as the present invention, described left column, right column are hydraulically extensible column.
By this lowering or hoisting gear of hydraulically extensible column, trash rack support bar and trash rack raising and lowering can be driven, and freely regulate the height of trash rack according to SEA LEVEL VARIATION, make what trash rack was in the best to block dirty position.
Further illustrating as the present invention, described trash rack support bar, draw-in groove and " returning " type block dirty support, snap fit adopts hard plastic board to prepare.
Needing long period of soaking in water because trash rack support bar, draw-in groove and " returning " type block the dirty parts such as support, snap fit, or be in the environment of high humility, the conventional parts adopting metal material to prepare cannot stand and get rusty and damage, thus forfeiture effect.And the parts adopting hard plastic board to prepare, rubbish thrust can be born and do not fracture, again can life-time service non-corrosive.
Further illustrating as the present invention, described trash rack support bar width is 7-15cm, and thickness is 0.5-1.5cm, and length selects according to trash rack quantity, it is preferable that trash rack quantity is 6.
Further illustrating as the present invention, described trash rack length is 1.6-2.4m, and wide for 0.8-1.2m, thickness is 0.2-0.6cm.
Further illustrating as the present invention, described snap fit is arranged at trash rack middle and upper part, and concrete and trash rack top distance is 0.4-0.6m.
By long term test, the present inventor grope and excellent have selected trash rack support bar and trash rack relatively rationally, the specification of science, and the link position that snap fit is optimum, the service life of the movable sewage blocking device of intake of hydropower station of the present invention can be extended better.
Compared with prior art, what the present invention reached has the technical effect that
