Abstract

The utility model relates to a drainage device of a fishpond. The device comprises a drainage opening in the bottom of a pond body, and an anti-escaping net, wherein the anti-escaping net is of a barrel-shaped structure and perpendicularly arranged on the drainage opening in a sleeved mode. According to the device, the perpendicularly-arranged barrel-shaped anti-escaping net is adopted, and therefore the defect that the drainage opening is blocked by excrement can be effectively avoided, smooth water exchange is guaranteed by increasing the area of water filtered by the anti-escaping net, and water inlet and out balance is achieved.

Description

Crawl drainage arrangement

Technical field:

The utility model belongs to aquaculture field, particularly a kind of crawl drainage arrangement.

Background technology:

Existing industrialized aquiculture pond, especially fish culture pond, all need water body to upgrade every day, to improve the oxygen content of water body, and discharges fish excreta and bait residue, in order to avoid polluted-water causes that fish disease occurs.For this reason, at the bottom of the discharge outlet of pond body is often located at the pond of low level, can reach the object of discharge without energy consumption.When discharge, in order to prevent that fish from escaping from, be often provided with the anti-net of escaping at discharge outlet place, depending on the size of cultivation fish body, change the anti-net of escaping of different meshes, especially cultivate the pond body of small fish, it is very little that discharge outlet anti-escapes net meshe, when discharge, is very easily plugged, and causes discharge smooth or block.Trace it to its cause, the anti-net of escaping of traditional discharge outlet all directly overlays discharge outlet place, is horizontal positioned, and sediments finally occurs blocking phenomenon above can being constantly superimposed upon.How to improve the deficiency in prior art, provide one to discharge filter cylinder smoothly, become the object of the utility model research.

Summary of the invention:

The purpose of this utility model is that a kind of anti-net of escaping of design becomes to be vertically set on the crawl drainage arrangement in discharge outlet at the bottom of pond.

Technical solutions of the utility model are achieved in that a kind of crawl drainage arrangement, comprise the discharge outlet of body bottom, pond and prevent escaping net, it is characterized in that preventing that escaping net becomes tubular structure, and vertical sleeve is located at discharge outlet place.

Described discharge outlet is provided with the double-deck anti-net of escaping outward, and it is little that internal layer prevents escaping net diameter, and mesh is large; It is large that skin prevents escaping net diameter, and mesh is little.

On the body bottom, pond of described discharge outlet peripheral circumferential, be welded with respectively three to four dead levers, dead lever upper end is provided with eyelet; Described skin is anti-escapes net and is located at the outer hand hay cutter of described complex root dead lever, and top is fixed on dead lever eyelet.

The utility model adopts the anti-net of escaping of vertically disposed tubular, can effectively avoid excreta to block the defect of discharge outlet, and the anti-area of escaping net filtration water of expansion, even excreta network blocking eye, also can to lower and on be layering, and prevent that escaping net remains the unimpeded of upper space, the exchange of assurance water body is carried out smoothly; In addition, for the draining of small fish body, also can adopt the double-deck anti-net of escaping, the especially outer anti-diameter of escaping net is larger, makes up outerly anti-ly to escape the throttling that small networks eye causes, and reaches the balance of Inlet and outlet water.

Accompanying drawing explanation:

Below in conjunction with concrete legend, the utility model is described further:

Fig. 2 crawl perspective exploded view

Wherein

1-pond body 2-discharge outlet 3-anti-anti-net of escaping of net 31-internal layer of escaping

32-outer anti-net 4-the dead lever of escaping

Embodiment:

See figures.1.and.2, the stereogram of crawl, this drainage arrangement, comprise discharge outlet 2 and the anti-net 3 of escaping of pond body 1 bottom, this prevents escaping 2 one-tenth tubular structures of net, and vertical sleeve is located at discharge outlet 2 places, is provided with the double-deck anti-net 2 of escaping in this legend, comprise anti-net 31 and the outer anti-net 32 of escaping escaped of internal layer, both are independently arranged on bottom, pond; It is little that internal layer prevents escaping net 31 diameters, and mesh is large; It is large that skin prevents escaping net 32 diameters, and mesh is little.

While cultivating larger fish, only need internal layer to prevent escaping net 31, its diameter is little, abdicate more breeding spaces, and larger mesh can discharge all excretions and bait residue in pond, does not also have plug-hole problem; When cultivation is compared with small fish childhood, eel seedling, needs to add the outer anti-net 32 of escaping, and it is little that skin prevents escaping net 32 meshes, and resistance of water drainage is large; And, while preventing that fry from escaping from, also can, by gears such as excretas at mesh place, produce and block or Choking phenomenon simultaneously, for this reason, that the anti-skin barrel dliameter of escaping net 32 need be done is larger, increases the area of filtered water, reaches the balance of Inlet and outlet water with this.

Internal layer prevents that escaping net 31 can directly be set in discharge outlet 2, form fixed relationship, escape net 32 and skin is anti-, need fix by following structure, also on the pond of discharge outlet 2 peripheral circumferential body bottom, be welded with respectively three to four dead levers 4, dead lever 4 upper ends are provided with eyelet; The outer anti-outer hand hay cutter of escaping net 32 and be set in described complex root dead lever 4, top is fixed on the eyelet of dead lever 4.

Claims

1. a crawl drainage arrangement, comprises the discharge outlet of body bottom, pond and prevents escaping net, it is characterized in that preventing that escaping net becomes tubular structure, and vertical sleeve is located at discharge outlet place.

2. crawl drainage arrangement according to claim 1, is characterized in that discharge outlet is provided with the double-deck anti-net of escaping outward, and it is little that internal layer prevents escaping net diameter, and mesh is large; It is large that skin prevents escaping net diameter, and mesh is little.

3. crawl drainage arrangement according to claim 2, is characterized in that being welded with respectively three to four dead levers on the pond body bottom of discharge outlet peripheral circumferential, and dead lever upper end is provided with eyelet; Described skin is anti-escapes net and is located at the outer hand hay cutter of described complex root dead lever, and top is fixed on dead lever eyelet.
