Abstract
The utility model relates to a floating type garbage barrier net which is composed of floating bodies, a flexible net, a cable and a fixing member, wherein the number of the floating bodies is at least two, the flexible net is connected with the fixing member through the cable and the upper edge of the flexible net is connected with each floating body. Compared with a garbage barrier grate, the floating type garbage barrier net has the advantages that the garbage cleaning frequency is obviously decreased because the garbage barrier area and the garbage containing capacity are increased, the economic loss caused by the way that the garbage is stopped to be cleaned because of power off is greatly decreased because the utility model can easily clean the garbage and the generated energy of a power station is effectively raised because the water head loss is very small. The utility model can be singly used and can also be matched with the garbage barrier grate, and the utility model is widely applied to middle-sized and small-size hydraulic power stations and can also be used for large-sized hydraulic power stations.
Description
The utility model relates to that a kind of and water-power plant are matching used to block dirty device.
Dirt in the river course (weeds, crops, household garbage etc.) is a kind of key factor that influences the power station operate as normal with floating wood, in order to prevent its infringement to generating set, the measure of being taked up to now is that the trashrack of being made by steel plate or steel bar is set before intake, though this kind trashrack can be realized the interception to dirt, has the following disadvantages; 1. in case will directly reduce intake water inlet area with dirt on the trashrack, increase the intake head loss, reduce power benefit; 2. it is little to block little, the dirty capacity of dirty area, thereby the frequency of removing contamination is higher, and dirt adheres to more not easy-clear; 3. if not stopping paying out motor removes contamination, then need dispose trash rake, and domestic existing trash rake costs an arm and a leg, poor performance.
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of new-type dirty device that blocks is provided, it can not only reduce head loss, increase block dirty area and dirt content, reduction remove contamination frequency, be convenient to artificial or machinery is removed contamination, and simple in structure, be easy to make, cost is low.
The purpose of this utility model is achieved in that with the flexible material making blocks dirty device main body part-garbage barrier net, and this device is installed in the intake less place of a distance flow rate of water flow before.
The dirty device that blocks that the utility model provides is made up of suspended solids, flexible net, hawser and fixed component.Suspended solids is at least two, and flexible net links to each other with fixed component by hawser, and its upper edge links to each other with each suspended solids.
Above-mentioned suspended solids both can be discrete attitude, also can connect with hawser each other, and link to each other with fixed component by hawser.
Fixed component is used for fixing flexible net, can be rigid column, can be anchor also, but be preferably anchor, if select anchor for use, needs two at least.
The suspended solids plastic production, can be designed to airtight hollow cylinder or airtight hollow strip shape body, the size of airtight hollow cylinder, airtight hollow strip shape body and number will be calculated definite according to the length and the width of flexible net with the buoyancy formula, reduce size on the basis of mechanics principle as far as possible and reduce number satisfying, to reduce cost.
Flexible net is made of fibers material, preferably selects nylon for use; The width of net is institute's installation place depth of water
Length is led wall to the concrete conditions such as length of river course bank according to the width in river course, installation place or water intaking and is determined; The size of mesh determines that according to the characteristic of dirt the area of each mesh is generally 0.004～0.01 square metre.
The dirty device that blocks of said structure is floated garbage barrier net, both can use separately, can be used with trashrack again.Be dragged to it before blowdown lock when removing contamination or before the flood spillway, starting gate is can automatic Rapid Cleaning clean, also can adopt manually and remove contamination.
The utility model is compared with trashrack and is had the following advantages:
1. block dirty area and increase more than 50%, thereby dirt content increases more than 50%, the frequency of removing contamination significantly reduces.
2. owing to be arranged on the intake less place (less than the mistake grid current speed of trashrack) of a distance flow rate of water flow before, the adhesion of dirt on flexible net is less, is easy to remove contamination.
Since change convenient, remove contamination be dragged to it before blowdown lock or before the flood spillway water clean or manually remove contamination, greatly reduce and shut down the economic loss of removing contamination and being caused.
4. the head loss that is caused is minimum, has improved the generated energy in power station effectively.
5. can raise with the fluctuation of water level or reduce, widely applicable.
6. simple in structure, cost is low.
The utility model and trashrack are used can reduce the trashrack load, reduce its frequency of removing contamination, and improves the generated energy in power station.
