Description

A kind of adjustable ocean current generating conflux cover
Technical field
This utility model relates to a kind of ocean current generating conflux device, is applied to ocean energy by ocean current development field.
Background technology
In order to tackle the problems such as global energy shortage, environmental pollution, New Energy is all sought making great efforts in countries in the world Source substitutes traditional fossil energy.Up to now, the novel fungible energy source that countries in the world are developed is main Have solar energy, a wind energy, ocean energy, biomass energy and nuclear energy etc., wherein ocean energy by ocean current due to reserves rich The advantage such as rich, load is steady, predictability is strong and enjoy favor, in development in recent years comparatively fast, become current One of ocean energy energy kind having development potentiality most.China has wide mainland coastline, and energy by ocean current resource is rich Richness, but major part marine site flow velocity is on the low side, cause the exploitation of China's energy by ocean current exist generating set difficulty in starting, Generated output is less, can the problems such as generating dutation is short, development cost is high.
Flow velocity can only be risen to certain certain value by the kuppe of integral type, and ocean current flow velocity is complicated and changeable, it is difficult to one In straight maintenance kuppe, flow velocity is generating set optimal flow rate, does not has a kind of kuppe to fit so far simultaneously Should multiple ocean current flow velocity.
Utility model content
For solving the problems referred to above, the utility model discloses a kind of adjustable ocean current generating conflux cover, adjustable Ocean current generating conflux cover is combined by three parts, adjusts conflux cover caliber size according to ocean current flow velocity size, Power generation device from sea current is installed on the middle position of conflux cover, makes generating set operate in optimal flow rate all the time In the range of, make generating set easily start, and improve the capacitation power of power generation device from sea current.
This utility model technical scheme just is:
A kind of adjustable ocean current generating conflux cover, described conflux cover is by support member, bool and connector group Conjunction forms, and its profile is that two end sections are big, the loudspeaker shaped passage that intermediate cross-section is little, described support member, Bool one end is connected, and connector one end is connected with support member, and the other end is connected with bool.
Further, described bool and connector are respectively equipped with the connection fixing hole of some mutual correspondences.
Further, described support member is directly connected to bool, or is connected by multiple connectors.
Further, described bool bends to specific bit along the inwall of connector and postpones, by bolt and Nut connects fixing to bool and connector.
Further, described support member, bool and connector material are glass fibre.
Further, the two ends of described loudspeaker shaped passage and intermediate cross-section size, by bool and company Fitting is fixed diverse location and is adjusted.
Further, it is provided with generating set at small bore in the middle of described conflux cover.
In this utility model, support member and bool can bear bigger flexural deformation, according to flow rate of water flow and Generating set model determines generating set optimum flow rate, adjusts conflux cover sectional dimension accordingly, support member, curved Bent part and connector have some fixing holes, by screw bolt and nut by support member and bool, support member and company Fitting, bool and connector are fixed, and can effectively realize the persistently efficiently capacitation of ocean current generator group.Work as current When flow velocity changes or ocean current generating size changes, first screw bolt and nut is opened, find and specify consolidating of position Determining hole, use screw bolt and nut to retighten, a set of adjustable ocean current generating conflux cover can meet simultaneously Multiple ocean current flow velocity and multiple ocean current generator packet size, add the scope of application of conflux cover.
The beneficial effects of the utility model are:
(1) conflux cover material is glass fibre, cheap, and intensity is high, and good toughness adapts to severe Marine environment.
(2) the conflux cover of venturi tube structure, increases flow rate of water flow, it is easy to generating set starts, and improves The capacitation efficiency of ocean current generator group.
(3) conflux cover is combined by three parts, adjusts conflux cover sectional dimension size according to flow velocity size, Realize the persistently efficiently capacitation of ocean current generator group.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model;
Fig. 2 is schematic internal view of the present utility model.
Wherein: 1, support member;2, bool;3, connector;4, bolt;5, nut;6, fixing Hole.
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, of the present utility model being embodied as is described further.
See accompanying drawing 1 and accompanying drawing 2, the utility model discloses a kind of adjustable ocean current generating conflux cover, by glass Glass fibrous material is made, be a kind of simple in construction, easy to loading and unloading, can improve ocean current flow velocity conflux dress Put.Use glass fibre, overcome the sea water erosion to device, and have enough intensity and toughness.
Conflux cover is made up of support member 1, bool 2 and connector 3, and three parts are in the corresponding position interfixed It is equipped with some fixing holes 6, by bracing frame 1 and bool 2, bracing frame 1 and is connected by bolt 4 and nut 5 Fitting 3, bool 2 and connector 3 are fixed.
It is big that conflux cover is designed as two end sections, and the form that intermediate cross-section is little, according to Venturi tube principle, flow Time identical, sectional area is the least, and flow velocity is the biggest, and therefore the Cross section Design of conflux cover increases the water at intermediate cross-section Stream flow velocity, generating set is arranged at intermediate cross-section, reduces the startup difficulty of generating set, unit from The energy obtained in current have also been obtained lifting, even low flow velocity also has higher capacitation power, conveniently sends out Group of motors starts.
Flow velocity according to local marine site and generating set model determine the sectional dimension of conflux cover, i.e. bool 2 Bending position.First support member 1 and corresponding the fixing of bool 2, support member 1 and connector 3 are found Hole 6, uses bolt 4 and nut 5 to be fixed, then bool 2 is bent to along the inwall of connector 3 Specify position, find bool 2 and the corresponding fixing hole 6 of connector 3, use bolt 4 and the nut 5 will Bool 2 and the fixing connection of connector 3, it is achieved the combination of conflux cover three part.
When the sectional dimension of conflux cover needs to adjust, by bolt 4 and the spiral shell of stationary curved part 2 and connector 3 Female 5 unclamp, and bend to bool 2 specify position, reuse bolt 4 and nut 5 is fixed, Convenient disassembly.
When conflux cover requires that cross section is less, it is possible to remove connector 3, be used alone support member 1 and bool 2.When conflux cover require cross section bigger time, by add multiple connectors 3, realize cross section meet size want Ask.
It can be said that this utility model conflux cover is a kind of device being effectively improved ocean current flow velocity, according to literary composition mound In pipe principle, conflux cover can produce conflux and swabbing action, admits more fluid in cover, improves Flow velocity in conflux cover, it is easy to generating set starts, and makes power generation device from sea current the most still have higher Capacitation.
