Abstract

The utility model discloses a device for lifting shallow sea bed nutrients by air injection. In the prior art, conventional sea bed nutrient lifting devices are high in energy consumption. The device comprises a floating platform, an air compressor, a sealed cabin, a vent pipe and an air outlet bracket. The air compressor is arranged on the floating platform. The sealed cabin is arranged at the lower part of the floating platform. Control equipment for controlling the operation of the air compressor and different types of sensors for detecting water body are arranged inside the sealed cabin. The output of the air compressor is connected with one end of the vent pipe, and the other end of the vent pipe is connected to the air inlet of the air outlet bracket. The air outlet bracket comprises a plurality of pipelines which are distributed uniformly and radially around the air inlet. Each pipeline is provided with an air injecting nozzle in the direction facing the sea surface. The device can lift up deep seawater by injecting air to the sea bed, so as to increase the concentration of nutrients in seawater on the sea surface. The device can overcome a series of problems during the pumping by a water pump and can work reliably under harsh marine environments.

Description

Seabed, a kind of shallow sea nutritive salt gas injection lifting device
Technical field
The utility model belongs to ocean equipment technology and Ocean Fishery Field, relates to seabed, a kind of shallow sea nutritive salt gas injection lifting device.
Background technology
Nutritive salt how much be one of key factor of a certain aquatic productivity height of decision.And in general marine site, the euphotic layer seawater that is fit to the fish growth breeding is compared with the bottom seawater, and what nutrient concentration will be low is many.How utilizing bottom seawater that artificial method will be rich in nutritive salt to rise to sea surface is the problem that people press for solution.
Yet because the particularity of marine environment, also very not comprehensive to the theoretical research of this aspect both at home and abroad, existing means mainly are to mix with surface seawater after utilizing water pump that the bottom seawater is evacuated to sea surface, but this hoisting way has significant limitation.At first, the lifting efficient of drawing water with water pump is not high, if water pump needs work every day several hours, then can consume significant amount of energy, considers that operating environment is the ocean, and replenishing of the energy also becomes very difficult; Secondly; The water surface area that this method can have influence on is too small, draws up next bottom seawater with after the euphotic layer sea water mixing, leans on marine stream and diffusion to improve peripheral nutrients in sea water concentration entirely; For some large-scale fishing grounds, this method needs multiple arrangement just can play better effects.
At present, domestic still do not have a kind of nutritive salt method for improving energy-efficient, easy and safe to operate.
Summary of the invention
The purpose of the utility model is the deficiency to prior art, and nutritive salt gas injection lifting device in seabed, a kind of shallow sea is provided.
The technical scheme that its technical problem that solves the utility model adopts is:
Nutritive salt gas injection lifting device in seabed, shallow sea comprises floating platform, air compressor, sealed compartment, breather pipe and the frame of giving vent to anger.
Floating platform is provided with air compressor, and the floating platform below is provided with sealed compartment, and the control appliance and the multiple sensors that detects water body of control air compressor operating is housed in described sealed compartment.
The output of air compressor is connected to an end of breather pipe, and the other end of breather pipe is connected with the air inlet of the frame of giving vent to anger, and also is provided with gas flowmeter on the gas outlet of air compressor, and described breather pipe is vertical with floating platform to be provided with.
The frame of giving vent to anger moves into gas port by many rhizospheres and is the radial pipeline that is uniformly distributed with and forms, and the direction of every pipeline towards the sea is provided with gas injection nozzle.
The utility model adopts the way of the gas injection from the seabed to promote deep sea water, thereby improves the nutrient concentration of sea surface seawater, can overcome a series of shortcomings of drawing water with water pump, reliably working under abominable marine environment.The utility model safety, efficient, and easy and simple to handle, for the sustainable development of sea fishery is offered help.

Embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
As shown in Figure 1, nutritive salt gas injection lifting device in seabed, shallow sea comprises floating platform 3, air compressor 1, sealed compartment 2, breather pipe 4 and the frame 5 of giving vent to anger.
Floating platform 3 is provided with air compressor 1, and floating platform 3 belows are provided with sealed compartment 2, and the control appliance and the multiple sensors that detects water body of control air compressor 1 work is housed in the sealed compartment 2.
The output of air compressor 1 is connected to an end of breather pipe 4, and the other end of breather pipe 4 is connected with the air inlet of the frame 5 of giving vent to anger, and also is provided with gas flowmeter on the gas outlet of air compressor, and breather pipe is vertical with floating platform to be provided with.
The frame 5 of giving vent to anger moves into gas port by many rhizospheres and is the radial pipeline that is uniformly distributed with and forms, and the direction of every pipeline towards the sea is provided with gas injection nozzle 6.
The method of utilizing said apparatus to carry out the nutritive salt lifting is:
Starter-generator; After treating that power supply is stable; Open the gauge tap of air compressor; The gas injection nozzle place of each seabed extension of arrival behind the compressed air gas coming through flowmeter that produces and the breather pipe, after gas pressure reached setting value in the extension of seabed, gas injection nozzle was opened and is begun gas injection in seawater.
The uniform and stable bubble that the gas injection nozzle place produces gets in the seawater; On the one hand; The mixed liquor averag density of this zone maritime interior waters and bubble seawater on every side reduces; In order to offset the effect that density reduces, the seawater regional movement that seawater that density is lower and bubble mixed liquor will density be high towards the upper strata can rise the seawater that marine deep layer is rich in high nutritive salt to the seawater upper strata; On the other hand, the great amount of bubbles that gets in the seawater has certain kinetic energy, can drive current during bubble floating, forms lift upwards, and then the seawater that marine deep layer is rich in high nutritive salt is risen to the seawater upper strata.
Fig. 2 is an open type gas injection system schematic diagram.The gas (source of the gas) of gas injection nozzle 6 ejections gets in the seawater, is the water environment of an opening around it.
Fig. 3 is a semi-open type gas injection system schematic diagram.The gas (source of the gas) of gas injection nozzle 6 mouths ejection gets in the seawater, and bank off sea is nearer on one side for water environment around it, and another side is open water environment.
