The three-dimensional trash rack comprises a frame, a front panel, side panels and a back panel; the front panel, the left side panel, the right side panel and the back panel form a frame structure with the shape of a three-dimensional trapezoid together with a frame; the front panel and the side panels are formed by a plurality of crossbands and a plurality of grids; the frame is provided with a hook and a pulley assembly, wherein the hook is fixed on the top surface of the frame; the pulley assembly are divided into a left pulley assembly and a right pulley assembly which are installed on two side surfaces of the back frame; and the back panel is fixed with a plurality of crossbands. The three-dimensional trash rack is characterized by strong drain grating capability, high strength, large drain grating area, small water head loss, convenient movement and the like.
Description
Technical field
The utility model relates to that a kind of river water generates electricity, controls flood and drains flooded fields, block dirty facility in diversion works and the various environment protection sewage treatment project.
Background technology
Trashrack is that water-power plant, diversion works are used for stopping rubbish such as bits by hydraulic turbine water, foreign material and prevents that the quilts such as people, animal that fall into water from pouring the device of blocking together in the hydraulic turbine, also can be used for the sewage draining exit of factory or municipal sewage.Existing trashrack is that vertical (or near normal) channel is installed in the channel, like this, drowning people, animal is not poured in the hydraulic turbine, and simultaneously, it also can block rubbish, foreign material etc.At present, the trashrack that adopts of most of medium waterpower generator station has single face, three-dimensional; Have unsteady; also have fixing; the floating type trashrack of open source literature report has Chinese patent: power station automatic pollutant removal device (application number is 91212822.4); it is a kind of power station floating bits automatic clearing apparatus; its architectural feature is that fixing trashrack is designed to rotating trashrack; reach the purpose of in time removing floating bits automatically; this apparatus structure is simple; cost is low; the energy automatic pollutant removal; solved the problem that fixing trashrack can not automatic pollutant removal make floating bits hoard loss head, eliminated of the harm of floating bits, protected generating equipment the power station.Three-dimensional fixed trashrack has the inventor's patent: hydraulic generator unit trashrack (application number is 00229669.1), it is the trashrack that a kind of suitable hydraulic generator unit water inlet catching rubbish uses, it is characterized in that whole trashrack is stereo structure, block dirty face and be made of grizzly bar or net piece, end face sideboard one end is connected with the trashrack framework with the axle center.When three-dimensional trashrack is placed the water inlet place, enlarge footprint, slowed down the obstruction speed of rubbish, kept discharge.Especially can improve generated energy 20% in the wet season, the end face sideboard is movable realizes clearing up automatically rubbish.More than first kind of structure complicated, compliance is not too wide, and second kind of structure is simpler, and is easy to manufacture, is convenient to promote the use of, but finds after practical application in a few years, also there are some problems in it: the one, move inconvenient.When the rubbish of interception reaches certain quantity, the towing difficulty; The 2nd, easy deformation, damage are soon.Because three-dimensional trashrack long period of soaking is in water, nearer apart from generator, discharge is very big, so, bigger to the durability influence.
Summary of the invention
The purpose of this utility model provides a kind of both effective catching rubbish, does not influence the flow of water again, can realize no drop, simple in structure, three-dimensional trashrack that durability is high, applied widely.
The utility model is realized in following mode:
Three-dimensional trashrack, comprise framework, front panel, side panel and rear board, front panel, left and right sides panel and rear board and framework are formed the frame construction that solid is trapezoidal, it is characterized in that: the front panel of this solid trashrack and side panel are made of some horizontal stripes and some grizzly bars, framework is provided with suspension hook and pulley assembly, suspension hook is fixed on the end face of framework, is installed in the two sides of afterframe about pulley assembly divides.
The grizzly bar of above-described front panel and side panel is vertical bar or hole reticular lamina.
Above-described rear board is fixed with some horizontal stripes.
This three-dimensional trashrack can be provided with base plate or not establish base plate.
The utility model has following advantage:
1. it is strong to block dirty ability.Because framework adopted stereochemical structure, make and block dirty ability and strengthened manyly, the single face trashrack is in operation, and blocks on the dirty plane because the rubbish in the water can be evenly distributed in, thereby cause serious clogging in the very fast time; And three-dimensional trashrack, because its trashrack bar is away from water inlet, current are more slow, make and push away the front portion and the top of amassing at trashrack in most of water float things, therefore can guarantee the normal operation of equipment in the long time.
2. the intensity height is durable.Because this three-dimensional trashrack has increased some horizontal stripes, makes interior sash posture structure firm further, anti-pressure ability is stronger, and its durability is higher more than 2 times than original same structure.
3. it is big to block dirty area.Be not subjected to the restriction of water inlet size.
4. head loss is little.Owing to block dirty face away from water inlet, the flow velocity of water is little, and when normally moving, the head loss of three-dimensional trashrack approaches zero rice, has guaranteed the efficient operation of equipment.
5. conveniently moving pulls easily.Owing to increased suspension hook and pulley assembly, the mode of removing contamination can realize variation, can promote trashrack and remove contamination, also can use motor machine to remove contamination, and realize that under the situation of the normal operation of unit moving water removes contamination, especially in the wet season, can make full use of waterpower resourses, improve the generated energy of generating set.

The specific embodiment
As shown in Figure 1, the utility model comprises framework 1, front panel 2, suspension hook 3, pulley assembly 4, side panel 5, rear board 6 and base plate 7, front panel 2, left and right sides panel 5, rear board 6 and base plate 7 and framework 1 are formed the frame construction of a trapezoidal formula of solid, suspension hook 3 is fixed on the end face of frame construction, and pulley assembly is installed in the two sides of framework 1 about 4 minutes.
Shown in accompanying drawing 2-3, front panel 2 and left and right sides panel 5 are made of some horizontal stripes 8 and some grizzly bars 9, and grizzly bar 9 can replace with the hole reticular lamina.
As shown in Figure 4, rear board 6 is made of some horizontal stripes 8, and grizzly bar or hole reticular lamina are not installed.
