Description
Technical field
The utility model is related to a kind of blowdown apparatus, more particularly to a kind of crab cultivation box blowdown apparatus.
Background technology
Crab cultivation box is a kind of instrument for propagating crab artificially, by means of this instrument can greatly improve crab the output value and
The quality of crab, but current crab cultivation box does not have good blowdown apparatus, often using regular overall water filling and whole
Body blowdown, such mode is unfavorable for the growth of crab, but also easily causes cross-infection, once ill crab occurs, if not
Find in time and process, it will cause crab collective by disease, mortality can be caused when serious, raiser is greatly damaged
Lose.Therefore, it is badly in need of developing a kind of blowdown apparatus that can be solved the above problems at present.
Utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, there is provided a kind of simple structure,
Filth-discharging effect is good, independence is strong and uses the crab cultivation box blowdown apparatus of stabilization.
The technical scheme that the utility model is used is：The utility model includes inner tube and is socketed in outer in said inner tube
Pipe, some pieces of connecting plates are provided between the outer wall of said inner tube and the inwall of the outer tube so that the outer wall of said inner tube with
Drain outlet, the bottom of the bottom less than the outer tube of said inner tube, the top of the outer tube are formed between the inwall of the outer tube
Top of the end higher than said inner tube.
Further, the bottom of said inner tube is provided with external screw thread.
Further, the connecting plate is the axial or described outer tube of strip connecting plate, the connecting plate and said inner tube
It is axially in parallel.
Further, the bottom of the connecting plate is exposed along the outer wall of said inner tube from the outer tube, and the connecting plate
Bottom be located at said inner tube bottom top.
Further, the quantity of the connecting plate is four, and four connecting plates are uniformly arranged in the drain outlet.
The beneficial effects of the utility model are：Because the utility model includes inner tube and is socketed in outer in said inner tube
Pipe, some pieces of connecting plates are provided between the outer wall of said inner tube and the inwall of the outer tube so that the outer wall of said inner tube with
Drain outlet, the bottom of the bottom less than the outer tube of said inner tube, the top of the outer tube are formed between the inwall of the outer tube
Higher than the top of said inner tube, when using, the bottom of said inner tube is established in the bottom of crab cultivation box and is communicated with the outside at end
It is logical.So, just can keep in crab cultivation box with the mutually level water level in said inner tube top come for cultivating then foster toward crab
When growing water filling in box, superfluous water just can enter the drain outlet from the bottom of the outer tube, then from the drain outlet
Top flows into said inner tube discharge, and the dirt in crab cultivation box can also be discharged along current.
Simultaneously as the bottom of said inner tube is provided with external screw thread.So, the bottom of said inner tube can be with crab cultivation box
It is threadedly coupled, can prevents crab from pushing over the utility model when activity, it is ensured that the stability of cultivation.
Further, since the bottom of the connecting plate is exposed along the outer wall of said inner tube from the outer tube, and the connection
The bottom of plate is located at the top of the bottom of said inner tube.So, when the utility model is installed, excessively installation can be prevented, it is ensured that
There is gap the bottom of the outer tube with the bottom of crab cultivation box, and then ensure that good pollution discharge capability.

Fig. 2 is the sectional view at another visual angle of the present utility model；
Fig. 3 is overall structure diagram of the present utility model；
Fig. 4 is the overall structure diagram at another visual angle of the present utility model.
Specific embodiment
As shown in Figures 1 to 4, in the present embodiment, the utility model includes inner tube 1 and is socketed in said inner tube 1
Some pieces of connecting plates 3 are provided between the inwall of outer tube 2, the outer wall of said inner tube 1 and the outer tube 2, so that said inner tube 1
Drain outlet 4, the bottom of the bottom less than the outer tube 2 of said inner tube 1, institute are formed between the inwall of outer wall and the outer tube 2
State the top of the top higher than said inner tube 1 of outer tube 2.So as to just keep identical with the top of said inner tube 1 in crab cultivation box
Come for cultivating, then toward in crab cultivation box during water filling, superfluous water can just enter the water level of height from the bottom of the outer tube 2
The drain outlet 4, then discharged from the top inflow said inner tube 1 of the drain outlet 4, and the dirt in crab cultivation box
Can be discharged along current.
In the present embodiment, the bottom of said inner tube 1 is provided with external screw thread 5.After so designing, the bottom of said inner tube 1 can
Be threadedly coupled with crab cultivation box, can prevent crab from pushing over the utility model when activity, it is ensured that cultivation it is steady
It is qualitative.
In the present embodiment, the connecting plate 3 is strip connecting plate, the axial direction of the connecting plate 3 and said inner tube 1 or
The outer tube 2 it is axially in parallel.Such design can guarantee that the connecting plate 3 is identical with the direction of current, so as to will not hinder
The flowing of current, it is ensured that the patency of blowdown.
In the present embodiment, the bottom of the connecting plate 3 is exposed along the outer wall of said inner tube 1 from the outer tube 2, and institute
State the top of the bottom positioned at the bottom of said inner tube 1 of connecting plate 3.It is such design can guarantee that install the utility model when,
Prevent excessively installation, it is ensured that there is gap the bottom of the outer tube with the bottom of crab cultivation box, and then ensure that good blowdown
Ability.
In the present embodiment, the quantity of the connecting plate 3 is four, and four connecting plates 3 are uniformly arranged on the blowdown
In passage 4.So can well ensure the stability of the utility model structure, can effectively extend the service life of product.
The utility model is applied to the technical field of crab cultivation box blowdown apparatus.
Although embodiment of the present utility model is described with practical solution, do not constitute and the utility model is contained
The limitation of justice, for those skilled in the art, the group according to this specification to the modification of its embodiment and with other schemes
Conjunction will be apparent from.
