Abstract
The utility model discloses a kind of north cold area utilizes micro-pore oxygenation technology to solve the device of pond fish overwinter, comprise spring check valve, T-shaped three-port structure, micro-pore oxygenation dish, one of spring check valve and T-shaped three-port structure is communicated with, and other two of T-shaped three-port structure are communicated with micro-pore oxygenation dish; This T-shaped three-port structure is made up of outer spiral shell Shu Jie, adhered threeway and pagoda joint, and outer spiral shell bundle saves one end and is fixedly connected with adhered threeway, and the outer spiral shell of the other end is connected with pagoda joint screw thread.The utility model adopts check valve connecting tee structure, and is located in the pond of surviving the winter by final micro-pore oxygenation dish, ensure that winter, pond was supported, overcomes again oxygen increasing tube in prior art and easily intake and cause bursting by freezing; Structure is ingenious, easy to use.
Description
Technical field
The utility model relates to technical field of aquaculture, especially a kind of device utilizing micro-pore oxygenation to solve Wintering.
Background technology
North high latitude cold zone pond farming fish safe overwintering is unusual the key link in producing, and traditional method takes hole of making a hole in the ice usually, puts into water pump or paddle aerator, utilizes its effect of stirring water to be melted by ice sheet, realizes oxygenation; Also the accumulated snow or on cleaning ice face or new water of annotating, increase illuminance, utilize phytoplankton photosynthesis to realize oxygenation.But improving constantly in recent years along with cultivation level, high-density breeding becomes the distinguishing feature of some regional aquacultures, brings the technology constantly progress of water quality management in breeding process thus.
Dissolved oxygen is the primary condition of Fish Survival, and in Yield Fish Culture Ponds, traditional oxygenation way can not meet current production requirements, and its drawback also starts to manifest:
One is that energy consumption is high, causes aquaculture cost to strengthen.For the paddle aerator that a power is 3KW; it can be about 10 mu by oxygenation area; in plant or the large aquaculture family of some scales; water surface for aquaculture area is at least more than 500 mu; realize effective oxygenation; need the paddle aerator of more than 50; its general power reaches more than 150kw; run 5 hours according to average every day, run 140 days year, its power cost is more than 3.1 ten thousand yuan; this is in north cold area; because the fish growth time is short, the culture-cycle is long, substantially increases aquaculture cost.In addition, traditional oxygenation way is moved and management maintenance oxygen increasing equipment due to needs, has to engage more workman, and according to this locality investigation display, at Wintering Period, generally every 100 mu of waters surface need to engage workman 2-3 people, and its cost of labor is 5-7 ten thousand yuan.Therefore, add the cost of cultivation, have impact on culture benefit.
Two are, tradition oxygenation way safety of surviving the winter is poor.Oxygen increasing equipment needs by artificial mode, and be transported to the region of specifying, safety coefficient is poor, particularly in recent years various places occur be drowned, the accident such as electric shock beaten alarm bell to pond safety in production.Need a kind of convenient, efficient, safe oxygenation method.
Utility model content
The utility model is for the deficiencies in the prior art, and propose a kind of device utilizing micro-pore oxygenation to solve Wintering, structure is ingenious, easy to use.
In order to realize above-mentioned utility model object, the utility model provides following technical scheme: a kind of device utilizing micro-pore oxygenation to solve Wintering, comprise spring check valve, T-shaped three-port structure, micro-pore oxygenation dish, one of spring check valve and T-shaped three-port structure is communicated with, and other two of T-shaped three-port structure are communicated with micro-pore oxygenation dish; This T-shaped three-port structure is made up of outer spiral shell Shu Jie, adhered threeway and pagoda joint, and outer spiral shell bundle saves one end and is fixedly connected with adhered threeway, and the outer spiral shell of the other end is connected with pagoda joint screw thread.
Further, also comprise plastic flexible pipe, this plastic flexible pipe is communicated with the entrance of spring check valve, and between spring check valve and T-shaped three-port structure.
Further, also comprise pvc pipe, this pvc pipe connects plastic flexible pipe and between spring check valve and T-shaped three-port structure.
Compared with prior art, the utility model has the following advantages: adopt check valve connecting tee structure, and final micro-pore oxygenation dish is located in the pond of surviving the winter, ensure that winter, pond was supported, overcome again oxygen increasing tube in prior art and easily intake and cause bursting by freezing; Structure is ingenious, easy to use.
Accompanying drawing explanation
Fig. 1 is that the utility model utilizes micro-pore oxygenation to solve the structural representation of the device of Wintering.
Embodiment
Be described in detail the utility model below in conjunction with accompanying drawing, the description of this part is only exemplary and explanatory, should not have any restriction to protection domain of the present utility model.
A kind of device utilizing micro-pore oxygenation to solve Wintering as shown in Figure 1, comprise plastic flexible pipe 1, pvc pipe 2, spring check valve 3, T-shaped three-port structure 4, micro-pore oxygenation dish 5, plastic flexible pipe 1 is with aeration device as fan blower etc. is communicated with, and the other end is communicated with spring check valve 3 entrance through pvc pipe 2; The outlet of spring check valve 3 is communicated with the arrival end of T-shaped three-port structure 4 through pvc pipe 2, plastic flexible pipe 1, pvc pipe, and other two of T-shaped three-port structure 4 are communicated with micro-pore oxygenation dish 5; This T-shaped three-port structure is made up of outer spiral shell Shu Jie, adhered threeway and pagoda joint 41, and outer spiral shell bundle saves one end and is fixedly connected with adhered threeway, and the outer spiral shell of the other end is connected with pagoda joint screw thread.
1), when this device is used for surviving the winter, in order to prevent when non-oxygenation, pond water enters the problem of plastic flexible pipe 1 frost heave.When it is installed, install according to the direction indication of spring check valve 3, one section, spring is inlet end.Described spring check valve two ends are connected by the outer spiral shell Shu Jieyu plastic flexible pipe of same bore (20mm), and are fixed with nylon cable tie.
2) connect with plastic flexible pipe one end branch pipe(tube) of supplying gas, other end linking springs formula check valve.And then with the plastic flexible pipe of identical material, spring check valve is connected with three-port structure.
3) described plastic flexible pipe is low-temperature resistant plastic flexible pipe, and caliber size and gas transmission branch pipe(tube) export and outer silk screw thread turns pagoda joint and matches.
4) described spring check valve is stainless steel, and type of attachment is internal thread, and version is elevation (over-and-under) type, and form is embolism formula; Inside nominal diameter (DN) is 20mm, nominal pressure 1.6MPa; Length is about 60mm.
The above is only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
