Abstract

A floating wind wave resisting fence relates to a novel wind wave resisting floating fence for aquaculture production and can adapt to water-level fluctuation and wind wave resistance. The floating wind wave resisting fence comprises double head lines, floaters, a fence net, a foot line and ground anchors, wherein a plurality of floaters are arranged on the double head lines so as to enable the upper edge of the fence net to float on the water surface, a plurality of ground anchors are arranged on the foot line, and the lower edge of the fence net is fixed underwater. The utility model mainly changes the structure that a fence stake and a cross rod are used for supporting the fence net in the prior art, and adopts a structure that the floaters and the ground anchor are used for supporting the fence net, the buoyancy of the floaters is used for enabling the upper edge of the fence net to float on the water surface, the foot line is fixed through the ground anchor, the fence net is enabled to be fixed, and the lower edge of the fence net is enabled to be clung to bottom mud. In case of water level fluctuation, the upper edge of the fence net goes up and down automatically with the water. In case of great storms, floating objects can go over the floaters, so that the fence net is avoided from being pressed. The fence has the basic function of keeping the breeding aquatic products and preventing the breeding aquatic products from escaping, and the flexible structure thereof also enhances the wind wave resisting capability of the fence.

Description

Floating wind wave resistance net encloses

Technical field

The utility model relates to a kind of water supply and produces breeding production and enclose with the floating net of novel anti stormy waves.

Background technology

According to People's Republic of China's marine industry standard " SC/T1091.1-2006 grass type lake net culture in enclosure plantation technology standard part 1: breed fish ", " SC/T1091.2-2006 grass type lake net culture in enclosure plantation technology standard part 2: support crab ", " SC/T1091.3-2006 grass type lake net culture in enclosure plantation technology standard the 3rd part: fish is raised together with by crab " and the explanation of Nanjing provincial standard technological documents such as " the big water surface seining cultivation of DB3201/T063-2004 technical regulations " and public situation, existing net culture in enclosure is grown facility generally by fence net, the mao bamboon stake, cross bar, compositions such as gabion, wherein insert in the mud mao bamboon stake bottom, pilespacing 1.5-4m ties up the support that becomes fence net with the cross bar knot; Gabion is that etting is made column can stone, and knot is tied up on infraclass, treads in the mud fixedly fence net.

The shortcoming that the facility existence is grown in above-mentioned net culture in enclosure mainly is to be not suitable for the waters big in the height of water, that stormy waves is big to use.When fluctuation in stage, need the manual adjustment net height, as when significantly rising, can not in time heightening fence net, will cause fence net to flood, aquaculture product is escaped; As fixing fence net, the above water fence net will speed up aging during non-flood season.When stormy waves was big, the impact that stake net waterborne is difficult to bear current, floating thing caused the fence net lodging.Existing net encloses and executes another shortcoming is that stake net waterborne stands in great numbers, and has destroyed natural landscape.

Summary of the invention

The utility model provides a kind of floating wind wave resistance net that can adapt to SEA LEVEL VARIATION, wind wave resistance to enclose at above problem.

The technical solution of the utility model is: comprise two headlines, float, fence net, infraclass and earth anchor, be provided with some floats on two headlines, the fence net upper limb is bubbled through the water column, be provided with some earth anchors on infraclass, the lower edge of fence net is fixed in the bottom.

Described float is fixedly connected between two the headline.Also be provided with two the headline, be separately fixed at the top and the below of float.

The utility model mainly is the structure that changes existing net skirt piles and cross bar support fence net, replace the structure that float and earth anchor support fence net, utilize the buoyancy of float that the fence net upper limb is emerged, guiding principle is fixed in the land used anchoring to be fixed fence net and makes the fence net lower edge be close to bed mud.When meeting fluctuation in stage, the fence net upper limb is automatically with the water lifting.When meeting high sea, floating thing can be crossed on float, avoids oppressing fence net.This kind net encloses and both keeps the basic function that prevents that aquaculture product from escaping, and its flexible structure has strengthened the capacity of anti-storm that net encloses again.Specifically one be solved that net encloses can not be with the problem of fluctuation in stage automatic lifting; The 2nd, solved following Netease of high sea situation lodging problem; The 3rd, solved the easily aging problem of above water fence net; The 4th, solve net and enclosed the problem of destroying natural landscape.

In use, one, net enclose can be with fluctuation in stage automatic lifting, facility waterborne reduces, wind area dwindles, capacity of anti-storm strengthens, and has saved the manpower of manual adjustment net height, suits to use in the big lake of the height of water; Two, floating net encloses the problem that do not lodge, and capacity of anti-storm is strong, suits to use in the big big water body of the height of water; Three, fence net has been avoided weathering all under water, and can extend to 6-8 service life from 3-5; Four, above water dwindles greatly, and the adverse effect that net is enclosed natural landscape drops to minimum; The 5th, stake makes float into cross bar can make whole net enclose cost of manufacture saving 40-50%.
