Abstract
The utility model relates to the field of water power engineering, in particular to a filter desilting type U-shaped channel. The filter desilting type U-shaped channel is formed by a trash rack speed reducing cylindrical frame, a filter screen, a channel bottom desilting valve and a U-shaped channel, wherein the whole U-shaped channel is divided into two sections, the U-shaped channel comprising a deepening section is a water treatment section, the other part of the U-shaped channel which is used for delivering filtered water flow is a water supply channel, water flow entering into the deepening section enters into the filter screen through an upstream surface and the bottom part of the filter screen, the desilting valve is arranged under the U-shaped channel, and the side surface of the U-shaped channel is provided with an overflow hole which is communicated with the water supply channel. According to the filter desilting type U-shaped channel disclosed by the utility model, the structure is simple, the technical requirement is not high, the water utilization rate of the U-shaped channel is high, farmland desertification can be prevented, surface water can be directly connected to a drip irrigation device after being filtered through a filter channel, the wish of directly using the surface water for drip irrigation is realized, and the water saving promotion has great technical significance.
Description
Technical field
The utility model relates to hydraulic engineering field, particularly a kind of filtration sand draining type U-shaped channel.
Background technology
At present mainly lean on trashrack with the U-shaped channel or filter specially that desilting works filters and sand discharge.Although it has certain filtration capability of sediment outflow, but compare itself with the U-shaped channel that this paper recommends and still had some problems, although it has certain dirty effect of blocking, trashrack can only be processed the larger foreign material of some volumes, if build special filtration desilting works, cost can be higher.Although use at present the flow velocity of water in the U-shaped channel very fast, the water delivery transportability of sediments is stronger, but have the desilting problem, this has just affected the conveyance power of water of channel, and causes the desertification in irrigated area.Do not reach the requirement of some efficient water-saving irrigation equipment because of the water quality of channel, so irrigation equipment can not directly use the water of channel, namely need further to process the foreign material in water, this has just increased the water-saving irrigation project investment greatly.General channel basically needs excavation or fills ground, and engineering quantity is large, influence ecological environment to a certain extent, and construction is subjected to the constraint of topography and geomorphology and weather conditions larger, and channel builds up the rear impact that easily is subjected to basic native frost heaving failure and underground water.
Summary of the invention
The purpose of this utility model is to provide a kind of filtration sand draining type U-shaped channel.Some practical problems that exist with the U-shaped channel that solves present use.
The purpose of this utility model is achieved in that it is by trashrack 1 deceleration cylinder frame 2, screen pack 3, at the bottom of canal, sand excluding valve 4, U-shaped channel 5 consists of, and whole U-shaped channel divides two sections, is the water treatment channel comprising the U-shaped channel of the section of deepening, after delivery of filtered, the part of current is feeder channel, the current that enter the section of deepening enter screen pack 3 from upstream face and the bottom of screen pack, and sand excluding valve 4 is housed under channel, and channel 5 sides have the spout hole that is connected with feeder channel.
use the beneficial effect of novel filtration sand draining type U-shaped channel to be: to adopt the overhead type structure, be not subjected to the impact of basic native frost heaving failure and underground water, basically do not need excavation or fill ground, the engineering construction climate, the constraint of orographic condition is less, be convenient to dismounting because adopting the overhead type structure, can reuse elsewhere, this just greatly reduces corresponding construction investment, constructability, reduction of erection time, there has been new breakthrough making material aspect, roughness is very little, compare water delivery with present channel, transportability of sediments is stronger, current are directly supplied with drip irrigation equipment by filtering after sand draining type U-shaped channel filters, realize that surface water is directly used in the hope of drip irrigation, be conducive to improve the utilization rate of irrigation water, prevent farmland desertification.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of facing of the utility model implementation column 1.
Fig. 2 is the side-looking structural representation of the utility model implementation column 2.
Fig. 3 is the plan structure schematic diagram of the utility model implementation column 3.
The specific embodiment
A kind of filtration sand draining type U-shaped channel, as Fig. 1, Fig. 2, shown in Figure 3, it is by trashrack 1 deceleration cylinder frame 2, screen pack 3, at the bottom of canal, sand excluding valve 4, U-shaped channel 5 consists of, and whole U-shaped channel divides two sections, is the water treatment channel comprising the U-shaped channel of the section of deepening, after delivery of filtered, the part of current is feeder channel, the current that enter the section of deepening enter screen pack 3 from upstream face and the bottom of screen pack, and sand excluding valve 4 is housed under channel, and channel 5 sides have the spout hole that is connected with feeder channel.
Claims (1)
