Description
Technical field
The utility model relates to a kind of screw and to breed fish pond on a hill bottom blow-down water device.
Background technology
The mountain and hill landforms of south China, have the pond on a hill of One's name is legion, not only make agricultural irrigation obtain guarantee, also improve able to resisting flood and drought ability.The tradition cultivation development model based on herding has also been broken in pond on a hill cultivation, start pond on a hill development aquaculture upsurge, be used as cultivation duck, goose and all kinds of freshwater fishes etc., open aquaculture new way, not only add income to the masses, also realize the common profit of economic and social benefit.Pond on a hill has the advantages that cultured area is large, water level is dark, yield potential is large.In recent years, along with the development of pond on a hill reservoir cultivation, changed to bait throwing in fertilising intensive culture type by extensive extensive cultivation type, frequent applying due to bait, medicine makes breeding water body eutrophication gradually, cause breeding water body contaminating endogenous, water quality deterioration is day by day serious, causes fish disease to take place frequently, feed conversion rate is low, and aquaculture cost increases.Tradition pond on a hill construction of breeding fish lacks bottom blow-down water device, and bottom water body exchangeability is poor, and dirt deposits, and causes water hypoxia bottom pond on a hill, poor water quality and affect cultivation.Current most of pond on a hill uses ancient layer-stepping stone valve, adopts wood plug, needs lower water manual work on the one hand during discharge water, and working strength is large, dangerous high; On the other hand these pond bottom sewerage facility equipment have been not suitable with intensive culture type pond on a hill and have breeded fish pattern.Also have some ponds on a hill of breeding fish to adopt pond on a hill reservoir drainage facility to carry out sewer, although discharge water is convenient, does not reach the effect of bottom blow-down, do not have the effect improving breeding water body.
Utility model content
The purpose of this utility model is for above weak point, the pond on a hill bottom blow-down water device that provides that a kind of structure is simple, easy to operate, the screw of low cost of manufacture is breeded fish.
The scheme that the utility model technical solution problem adopts is, a kind of screw is breeded fish pond on a hill bottom blow-down water device, comprise blowdown tank, the one side of described blowdown tank is provided with fish screen, and the another side of blowdown tank is fixed with blow-off pipe, and chimeric in described blowdown tank have gate, described gate is fixed with nut, described nut is bolted with screw rod, and one end of described screw rod is fixed with rocking bar, and the other end of described rocking bar is provided with the handle for regulating gate opening and closing.
Further, described blowdown tank is the square of masonry of cement mortar or the body structure of cuboid, offers the groove for accommodating gate in blowdown tank, and the groove width of described groove is slightly larger than the gate-width of gate.
Further, described fish screen is the net grid structure that is welded of round steel or wire netting.
Further, described rocking bar is provided with some bearings, described bearing is fixed with bearing block, described bearing block is connected on earth construction.
Further, on the mid point that described nut is arranged on the axis of gate and summit, described nut and screw rod are made by antirust material.
Compared with prior art, the utility model has following beneficial effect: the utility model structure is simple, easy to operation, low cost of manufacture, sewage and sedimental automatic removal bottom pond on a hill is realized by the opening and closing of rotary handle regulating gate, maintenance cultivating system water quality is pure and fresh, environment good, thus promotes healthy growth, the raising cultured output of cultured fishes.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model patent is further illustrated.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is partial structurtes schematic diagram of the present utility model.
In figure:
1-nut, 2-fish screen, 3-screw rod, 4-rocking bar, 5-handle, 6-bearing block, 7-gate, 8-blowdown tank, 9-blow-off pipe, 10-groove.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.
As shown in Fig. 1 ~ 2, a kind of screw is breeded fish pond on a hill bottom blow-down water device, comprise blowdown tank 8, the one side of described blowdown tank 8 is provided with fish screen 2, and the another side of blowdown tank 8 is fixed with blow-off pipe 9, and chimeric in described blowdown tank 8 have gate 7, described gate 7 is fixed with nut 1, described nut 1 is bolted with screw rod 3, and one end of described screw rod 3 is fixed with rocking bar 4, and the other end of described rocking bar 4 is provided with the handle 5 for regulating gate 7 opening and closing.
In the present embodiment, described blowdown tank 8 is the square of masonry of cement mortar or the body structure of cuboid, offers the groove 10 for accommodating gate 7 in blowdown tank 8, and the groove width of described groove 10 is slightly larger than the gate-width of gate 7.
In the present embodiment, the net grid structure that is welded for round steel of described fish screen 2 or wire netting.
In the present embodiment, described rocking bar 4 is provided with some bearings, described bearing is fixed with bearing block 6, described bearing block 6 is connected on earth construction.
In the present embodiment, on the mid point that described nut 1 is arranged on the axis of gate 7 and summit, described nut 1 and screw rod 3 are made by the antirust material such as copper or stainless steel, prevent from nut 1 and screw rod 3 from getting rusty under water to kill, described screw rod 3 length is 1.5 ~ 2 times of bulkhgead gate 7 length, ensures that gate 7 can be opened completely; Screw rod 3 is fixedly connected with by flat key with rocking bar 4, and rocking bar 4 is fixedly mounted on the pedestal on pond on a hill earth embankment dam by bearing block 6.
In the present embodiment, blowdown tank 8 is arranged on the lowermost end of pond on a hill dykes and dams, and blowdown tank 8 parallels with dykes and dams are domatic, during blowdown, sewage is discharged away together with mud, prevents mud from hoarding for a long time bottom pond on a hill, forms larger pollution to water quality, the health of effective maintenance cultivating system water quality, for cultured fishes provide good breeding environment.
Specific implementation process: during use, need starting gate 7, only need turning handle 5, handle 5 drives screw rod 3 to rotate, because screw rod 3 is fixedly connected on dykes and dams, the rotation of screw rod 3 self is not subjected to displacement but drives nut 1 to be subjected to displacement and then to drive gate 7 to move up opens blowdown tank 8, sewage is just flowed to blow-off pipe 9 by blowdown tank 8 together with mud, arranging of fish screen 2 ensures that cultured fishes can not be taken away by sewage, ensure that the safety of fish, during closed shutter 7, only need counter-rotation handle 5, handle 5 is fully closed until cannot just represent gate 7 in rotation.
Above-listed preferred embodiment; the purpose of this utility model, technical scheme and advantage are further described; be understood that; the foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
