Beneficial effect:
Compared with existing correlation technique, the present invention has following beneficial effect:
The utility model is according to the lifting situation of water level, the position of garbage cleaning device can be regulated by electric block, screen pack on cleaning plant is that screen pack is made, can not affect the unimpeded of current, when water flows through screen pack, the rubbish on the water surface is drained in dustbin through screen pack, very easy to use, and structure is simple, cheap, save a large amount of manpower and materials.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention for power station dirt cleaning system;
Fig. 2 is the structural representation of screen pack of the present invention.
Detailed description of the invention
Below in conjunction with Figure of description, the present invention will be further described.
As shown in Fig. 1 to 2, the present embodiment is used in power station dirt cleaning system the utility model embodiment, comprise electric block, dustbin, carriage and cleaning plant, electric block 1 is arranged on bank, two sides, carriage comprises slide rail 2 and coaster 3, bank, two sides is equipped with a pair opposing parallel slide rail 2, and the slide rail 2 of two sides is corresponding, coaster 3 and slide rail 2 are slidably connected, make garbage cleaning device can according to the change of water level on the water surface, adjust the position of self, cleaning plant comprises support 4, screen pack 6 and rotating shaft 5, rotating shaft 5 is fixed on the two ends up and down of support 4, with motor in rotating shaft 5, screen pack 6 is sleeved in rotating shaft 5, screen pack 6 is made for screen pack, the unimpeded of current can not be affected, when water flows through screen pack 6, rubbish on the water surface is transported in dustbin 8 by screen pack 6, very easy to use, coaster 3 is fixedly connected with support 4, the rear of conveying device is provided with dustbin 8, dustbin about 8 two ends are all fixed on support 4 by crossbeam 9, crossbeam 9 is provided with sling 10, wire rope 7 is provided with between two electric blocks 1, wire rope 7 is successively through the sling 10 on crossbeam 9.
The present embodiment screen pack comprises the inner filtration structure 61 be made up of filter core or filter screen 63, and the outer filtration 62 to be made up of filter fiber felt 64, roll fashion can be adopted to be wrapped in filter core for filter fiber felt 64 or filter screen 63 is outside, and spiral wrap also can be selected in filter core or filter screen 63 outside.Screen pack is inclined to set in filtration system 65.In general, screen pack and current or airflow direction are 30 ~ 45 °.
Incline structure is adopted by screen pack to be arranged in filtration system 65, by increasing the contact area of screen pack and current or air-flow, to increase the filtration treatment amount in the unit interval.At filter core or filter screen 63 outer wrap filter fiber felt 64, by filter core or filter screen 63 and the overlapping combinations of filter fiber felt 64, reach the object of double filtration.Generally, filter effect is directly proportional to the parcel number of plies of filter fiber felt 64, and namely the relative number of plies of filter fiber felt 4 is more, and filter effect is better, but the relative number of plies of filter fiber felt 64 is also determined by the filtration environment of reality, not The more the better.And filter fiber felt 64 is mobilizable connection at filter core or filter screen 63 outside, when filtrate deposition is too much on filtration fibrofelt 64, filter fiber felt 64 can be taken off and carry out clearing up or changing.
Therefore, in the utility model, filter core or filter screen 63 mainly play fixed supporting role, and filter fiber felt 64 mainly plays filter cleaning effect.By use of the present utility model, the application life of filter core or filter screen 3 effectively can be extended.According to the requirement of filtration yield, can arrange along current or airflow direction in same filtration system and organize composite filter net, to strengthen filter effect more.
When water level changes, the position of garbage cleaning device can be adjusted by electric block 1.Described clears up system for power station dirt, also comprise the level alarm for water be arranged on below described screen pack, described level alarm for water comprises, first water level alarm, second water level alarm, 3rd water level alarm, wherein, described first water level alarm distance distance is on the bank the first distance, described second water level alarm distance distance is on the bank second distance, described 3rd water level alarm distance distance is on the bank the 3rd distance, wherein, the value of described first distance is greater than the value of described second distance, the value of described second distance is greater than the value of described 3rd distance, the first described water level alarm, second water level alarm, 3rd water level alarm passes through solar cell for supplying power.
By the change of described level alarm for water sensed water level, when water level changes, the position of garbage cleaning device can be adjusted by electric block 1.
The present invention be should be understood that; above-described embodiment; further detailed description has been carried out to object of the present invention, technical scheme and beneficial effect; these are only embodiments of the invention; be not intended to limit the present invention, every within spiritual principles of the present invention, done any amendment, equivalent replacement, improvement etc.; all should be included within protection scope of the present invention, the protection domain that protection scope of the present invention should define with claim is as the criterion.
