Embodiment Construction

[0016] The following examples further illustrate the invention but are not to be considered as limiting.

[0017] As shown in Figure 1, a mobile sewage cover for intensive shrimp ponds is composed of an operating panel 1, an operating rod 2, a conical pressure-resistant cover 3, a fence 4 and a base 5;

[0018] The top of the operating rod 2 is connected to the cross bar of the operating panel 1; the middle part is welded to the top of the pressure-resistant cover 3;

[0019] The fence 4 has upper and lower two annular fixed rings 4-1, 4-2, and the fence vertical bars are welded on the fixed rings 4-1, 4-2; the lower fixed ring 4-2 is welded with three-way stringers 4- 3. The center of the stringer is welded to the bottom of the operating rod 2; the steel plate thickness of the compression cover 3 is 2.5 mm, the lower part is welded on the top of the fence 4, and four ring-shaped fixing cards 4-4 are welded around the lower fixing ring 4-2; the base 5Reserved screw holes 5-1 ...

Abstract

This invention relates to an intensive shrimp pond with a mobile sewage enclosure. It includes operating set (1), operating leverage (2), topiary resistance shield (3), fencing (4) and the base (5); Operating rod (2) top connects to operating set (1) the cross bar; Central welds to resistance shield (3); Fencing (4) has two of up and down ring fixed coil (4-1, 4-2), The fence vertical welds to fixed coil (4-1, 4-2); the lower fixed coil (4-2) welds a truss to three (4-3), truss central connects to operation of the bar (2) the bottom welding; compressive shield (3) welds to the lower part the fence (4) the top; the lower fixed coil (4-2) welds three to six fixed card (4-4); the base (5) reserves socket (5-1); cradle simultaneously reserves card mouth and the inner wall of the entrance arch 45 degrees (5-2). The advantage of this invention is simple structure, low cost, corrosion resistance, anti-hypertension, secure and efficient, easy to maintain, mobile.

Description

technical field [0001] The invention relates to a mobile sewage discharge cover for an intensive shrimp pond. Background technique [0002] Shrimp farming is a pillar industry of aquaculture. The new model of shrimp farming—intensive farming with water (also known as high-level pond farming) has gradually replaced the extensive tidal farming model. The water-lifting intensive culture pond (prawn high-level pond) is generally square or round, with an area ranging from 4 to 10 mu, and an effective water depth of about 2m; the shrimp pond adopts cement slope protection, and an anti-seepage geomembrane is laid on the bottom of the pond; the center of the shrimp pond is designed with Sewage well. During the breeding process, due to the installation of an oxygen-increasing water truck, the water body is kept rotating while providing enough dissolved oxygen in the water body, so that the residual bait and feces are concentrated in the center of the shrimp pond, and then discharged...
