Description

A kind of artificial sinking device
Technical field
This utility model relates to marine settings technical field, particularly relates to a kind of artificial sinking device.
Background technology
Coastal area is global most important modern Economy Development region.According to statistics, the area within more than the 50% of world population is gathered in offshore 60 kilometers.In China, the coastal area accounting for whole nation land surface 13% carries the population of more than 40%, creates the national total output value of more than 60%.But, current Layer Near The Sea Surface faces the problems such as marine environmental pollution, environmental destruction, living resources are exhausted, bio-diversity drastically declines, water hypoxia, harmful algal take place frequently, and makes the Faced In Sustainable Development baptism of coastal area.
Wherein, water body " anoxia " (hypoxia) refers to that the oxygen content of water body is less than 2mg/L.Anoxia water body is also referred to as " the dead district " of aquatic organism.Along with the increase of anoxia occurrence frequency, anoxia makes large number of biological zone of action be restricted, and even causes ocean disaster.At present, the anoxic zone that the whole world has been reported is more than 470, and China's East Sea Yangtze River Estuary and its adjacent sea areas is one of them.From late 1950s just it has been observed that Outer Changjiang estuary near-bottom water body has anoxia phenomenon, anoxic zone area to be about 1000km2.The most substantially verify, there is the ellipse hypoxia areal area of a south-north direction in Outer Changjiang estuary, its core is at 31.5 ° of N, 123 ° of E areas adjacent, dissolved oxygen (Dissolved Oxygen, the DO) concentration anoxic zone area less than 2mg/L is about 3000~4000km2, as shown in Figure 1.Reason and Eco response thereof that entrance of Changjiang River anoxia zone type becomes are complicated and changeable: the anoxia being diffused as this region water body of Changjiang Diluted Water provides nutritive salt support, Taiwan warm current's water invasion and upper up-flow are that anoxia water body provides less dissolved oxygen background value, and strong water body stratification prevents bottom oxygen and the vertical exchange of upper strata hyperoxia band.Up to now, scientific observation and understanding are lacked for anoxic zone, Outer Changjiang estuary marine site and long term evolution situation thereof.In view of the impact of the factors such as red tide aggravation, the anoxia phenomenon in this marine site can deteriorate further.Therefore, it is highly desirable to design set of device to improve the ecological environment of anoxic zone.
Utility model content
The purpose of this utility model is the present situation continuous worsening for the ecological environment of anoxic zone, entrance of Changjiang River, proposes a kind of artificial sinking device, and upper strata oxygenated water can be transported to Di Cheng anoxic zone, improve anoxic zone ecological environment by this device constantly.
In order to achieve the above object, the technical scheme that this utility model is used is as follows: a kind of artificial sinking device, including body portion and artificial marine habitat part;Wherein, described body portion is arranged in artificial marine habitat part, and the bottom of artificial marine habitat part is fixedly connected with some spud piles;Described body portion includes body body, mouth of pipe baffle plate and empennage;Fixing connection mouth of pipe baffle plate on the upper end outer wall of described body body;Described empennage is elongate steel plate, is fixed on the outer wall of body body;Described empennage place plane is mutually perpendicular to described mouth of pipe baffle plate place plane;The width of described mouth of pipe baffle plate is more than the external diameter of body body;Described artificial marine habitat part is the cuboid that centre has Venturi type groove, and described body body is connected with Venturi type groove;The opening direction of described Venturi type groove is perpendicular with mouth of pipe baffle plate.
Further, the left and right sidewall of described artificial marine habitat part the most also has some grooves.
Further, the material of described body portion is 316 rustless steels, and the material of described artificial marine habitat part is concrete.
Compared with prior art, have has the advantages that this utility model: this device is cheap, it is not necessary to long-term nurse and maintenance;Need not energy resource supply, energy-conserving and environment-protective;Artificial marine habitat part is for Fish Survival and breeding;Anoxic zone ecological environment can be effectively improved.

Detailed description of the invention
Below in conjunction with embodiment, this utility model is described further.
As Figure 1-5, a kind of artificial sinking device, including body portion 1 and artificial marine habitat part 2;Wherein, described body portion 1 is arranged in artificial marine habitat part 2, and the bottom of artificial marine habitat part 2 is fixedly connected with some spud piles 3;Described body portion 1 includes body body 11, mouth of pipe baffle plate 12 and empennage 13;Fixing connection mouth of pipe baffle plate 12 on the upper end outer wall of described body body 11;Described empennage 13 is elongate steel plate, is fixed on the outer wall of body body 11;Described empennage 13 place plane is mutually perpendicular to described mouth of pipe baffle plate 12 place plane;The width of described mouth of pipe baffle plate 12 is more than the external diameter of body body 11;
Described artificial marine habitat part 2 is the middle cuboid having Venturi type groove 21, and the left and right sidewall of described cuboid the most also has some grooves 22, for providing the hiding-place hiding stormy waves and natural enemy to Fish;Described body body 11 is connected with Venturi type groove 21;The opening direction of described Venturi type groove 21 is perpendicular with mouth of pipe baffle plate 12.
The material of described body portion 1 is 316 rustless steels, and the material of described artificial marine habitat part 2 is concrete.
Work process of the present utility model is as follows:
During this device cloth is put into water, empennage 13 is due to the effect of ocean current so that body portion 1 rotates to the position that empennage 13 is parallel with ocean current, i.e. Venturi type groove 21 together with artificial marine habitat part 2 and faces toward come flow path direction.Owing to ocean current is blocked by mouth of pipe baffle plate 12 so that ocean current shunts from mouth of pipe baffle plate 12 left and right sides, thus form an almost nil region of flow velocity in the upper end of body body 11;Owing to artificial marine habitat part 2 uses the such structure of Venturi type groove 21, when ocean current is through Venturi type groove 21, ocean current flow velocity in Venturi type groove 21 increases, and the flow velocity at the lower end mouth of pipe of the body body 11 being connected with Venturi type groove 21 is enlarged;From bernoulli principle, a negative pressure is there is at the lower end mouth of pipe of body body 11, and at the upper end mouth of pipe of body body 11, it is almost normal pressure, such that it is able to the oxygen-containing sea water at the upper end mouth of pipe of body body 11 to be transported to the bottom anoxic zone at the lower end mouth of pipe of body body 11, form sinking.
