Abstract
The utility model relates to a fish catching device of an alpine and gorge region hydropower station. The fish catching device of the alpine and gorge region hydropower station is convenient to use and practical, makes full use of characteristics of the hydropower station, and aims to resolve the problem of how to successfully and conveniently catch fishes on a downstream river channel of a dam. According to the technical scheme, the dam back type plant hydropower station is built in an alpine and gorge region, and the downstream of a hydropower station plant unit is sequentially provided with a plant tail tailrace and an apron. The fish catching device is characterized in that a row of gate piers are transversely built between the plant tail tailrace and the apron in the direction of water flow, the upstream side and the downstream side of every two adjacent gate piers are respectively provided with a vertical intercepting net capable of rising and falling and form a unit space, a fish catching net bag capable of rising and falling is arranged in each unit space, and a fish collecting room and a traffic hole communicated with an upstream reservoir area are arranged nearby the outermost unit space. The fish catching device is suitable for being built at the tail end of the tail tailrace of the dam back type plant hydropower station in the alpine and gorge region.
Description
Technical field
The utility model relates to the fishing facility in a kind of high mountain gorge power station, is applicable to build in the power house at dam toe tailrace end of high mountain and steep gorge area.
Background technology
Current domestic fishing facility is varied, but less for the fish pass structure in power station, mainly adopts fish pass, fish gathering machine or builds fish gathering harbour and fished for the modes such as dam.The power station of building on river, high mountain and steep gorge area, due to topographic and geologic reason, built fish pass very difficult, and the domestic power station of fish gathering machine mode uses less, fishes for the mode on dam and uses relatively many.In the success of dam downstream river course and catch easily fish, be how a difficult problem.Therefore studying convenient and practical fishing facility, and make full use of the feature in power station self, is a significant design.
Summary of the invention
The technical problems to be solved in the utility model is: for the problem of above-mentioned existence, provide a kind of convenient and practical, and make full use of the fishing facility in the high mountain gorge power station of the feature in power station self, how to solve in the success of dam downstream river course and the problem of catching easily fish.
The technical scheme that the utility model adopts is: the fishing facility in a kind of high mountain gorge power station, there is the power house at dam toe power station of building high mountain and steep gorge area in, the downstream of powerhouse of hydropower station unit is followed successively by factory building tailwater channel and apron, it is characterized in that: between described factory building tailwater channel and apron, laterally build one in the face of water (flow) direction and arrange gate pier, often adjacent two gate piers is upper, downstream all arranges liftable vertical catch net and forms a unitary space, liftable fishing net bag is set in each unitary space, near a unitary space of keeping to the side most, arrange fish gathering room and the access tunnel towards reservoir area, upstream.
The described top across each unitary space, builds an access bridge that leads to fish gathering room.
The beneficial effects of the utility model are: 1, the utility model takes full advantage of the design feature in factory building power station self, build conveniently, cost-saving.2, this fishing facility element number is many, and automated control operation is simple, convenient and practical.
Accompanying drawing explanation
Fig. 1 is layout plan of the present utility model.
Fig. 2 is that the utility model is implemented schematic diagram.
The specific embodiment
As shown in Figure 1-2, the fishing facility in the high mountain gorge power station of the present embodiment is mainly built the power house at dam toe power station of high mountain and steep gorge area in, and it comprises factory building tailwater channel 3 and the apron 9 in factory building unit 8 downstreams.The flow path direction that meets water between factory building tailwater channel 3 and apron 9 is built row's gate pier 1.Thereby the upstream and downstream between adjacent two gate piers all arrange vertical catch net 2 and form a unitary space, object is that the fish that attracted to factory building tailwater channel 3 are driven to this unitary space, in each unitary space, be provided with the fishing net bag 4 that can control lifting simultaneously, can easily the fish of interception be caught.Near a unitary space of keeping to the side most, arrange the fish gathering room 6 that automatic control equipment has been installed, fish gathering room connects again the access tunnel 7 towards reservoir area, upstream.
Across each unitary space, build an access bridge 5 that leads to fish gathering room 6 at gate pier top, fish transportation vehicle is first transported to fish gathering room 6 by access bridge 5 by the fish that catch and concentrates arrangement, and then is transported in reservoir area, upstream unified fish through access tunnel 7, completes the dam of crossing of fish.
The specific works principle of the present embodiment is as follows:
Before factory building utilized head generating, more than first the vertical catch net 2 of gate pier 1 upstream and downstream and fishing net bag 4 being mentioned to water surface curve on all.In the time that factory building generates electricity, under the tail water let out can attract the fish of downstream river course in factory building tailwater channel 3 set of regions.Wait to stop generating or part of generating units out of service before, vertical downstream catch net 2 and fishing net bag 4 are all placed under water, etc. then all or part of unit stops after generating, downstream tailwater level declines, be gathered at the beginning the fish river course parade downstream in factory building tailwater channel 3 or adopt the way of driveing to allow fish gather in the passage between gate pier 1, finally vertical upstream side catch net 2 is put down, fish are all besieged between gate pier 1, shut the upstream and downstream side net door of the fishing net bag 4 being placed in advance between gate pier 1 by automation control appliance simultaneously, and mention fishing net bag 4, thereby the fish of 1 of gate pier are all caught.Small-sized fish transportation vehicle is transported to the interior concentrated arrangement in fish gathering room 6 by access bridge 5 by fish, around dam access tunnel 7, the fish that catch is transported in reservoir area, upstream more afterwards with large-scale fish transportation vehicle warp, completes the dam of crossing of fish.
