Abstract
The purpose of the present invention is to propose to a kind of crab anti-escape networks easy for installation, at low cost.Crab anti-escape network of the invention includes pillar, metal mesh and anti-escape top plate, and the side of the pillar is equipped with several hooks, and the top of pillar is equipped with screw hole, and anti-escape top plate is installed on the top of pillar using the bolt across anti-escape top plate and the screw-in screw hole.When building crab anti-escape network, pillar is well placed first, in accordance with scheduled spacing, and metal mesh is placed in the side of pillar, then pillar is passed down through the mesh of metal mesh and be inserted on the ground, to which pillar is perpendicularly fixed at around crab farming pond, and caught on metal mesh using hook, make anti-escape network be difficult to move up under crab and other external forces；Finally anti-escape top plate is placed on downwards above pillar and metal mesh again, is fixedly connected with anti-escape top plate with pillar using bolt, completes the construction of crab anti-escape network.Crab can not climb over upwards anti-escape top plate and cross anti-escape network, to play anti-escape purpose.
Description
Technical field
The invention belongs to technical field of aquaculture, and in particular to the escaping-preventing facilities used into crab cultivation.
Background technique
River crab has very strong flight ability, and the quality of escaping-preventing facilities selection directly affects the rate of recapture of crab farming.Often at present
As crab escaping-preventing facilities be using made of cement plate.With precast reinforced concrete grow up 1 meter, it is 0.8~1.0 meter wide, thickness 2~
3 centimetres of cement plate, along ridge surrounding be laid with, cement plate enter ground 30~40 centimetres, 50~60 centimetres above ground level, plate with
It is smoothed out between plate with cement, inner wall keeps smooth as far as possible, wall base compacting, and it is 20~30 centimetres that a width is pressed on cement plate top
Iron sheet prevents river crab from fleeing.The investment of above-mentioned crab escaping-preventing facilities is big, and many raisers are difficult to bear.
Summary of the invention
The purpose of the present invention is to propose to a kind of crab anti-escape networks easy for installation, at low cost.
Crab anti-escape network of the invention includes pillar, metal mesh and anti-escape top plate, if the side of the pillar is equipped with cladding
Hook, the top of pillar are equipped with screw hole, and anti-escape top plate utilizes the bolt across anti-escape top plate and the screw-in screw hole to be installed on pillar
Top.
When building crab anti-escape network, pillar is well placed first, in accordance with scheduled spacing, and metal mesh is placed in branch
Then pillar is passed down through the mesh of metal mesh and is inserted on the ground, so that pillar is perpendicularly fixed at crab farming by the side of column
Around pond, and metal mesh is caught on using hook, anti-escape network is made to be difficult to move up under crab and other external forces；Most
Anti-escape top plate is placed on downwards above pillar and metal mesh again afterwards, is fixedly connected with anti-escape top plate with pillar using bolt, is completed
The construction of crab anti-escape network.Crab can not climb over upwards anti-escape top plate and cross anti-escape network, to play anti-escape purpose.
Further, which further includes anti-escape bar, and the top of the anti-escape bar is connected by hook and metal mesh
It connects, anti-escape bar is inserted into underground, the bottom of metal mesh can be firmly adjacent to ground and fixation, avoid crab from metal mesh
Lower section is fled from.
Further, for convenience of insertion underground, the bottom end of the pillar is cone cell, and the bottom end of the anti-escape bar is cone cell.
Further, the bolt is located at the centre of anti-escape top plate, and the two sides of the anti-escape top plate are located at metal mesh
Two sides, the anti-escape top plate is equipped with the limiting slot that Open Side Down, the top card of the metal mesh in the position of corresponding metal mesh
In limiting slot.Metal mesh is located at limit of the part by limiting slot between two pillars, will not arbitrarily shake, improve
Stability；And by setting limiting slot, the spacing between metal mesh top and anti-escape top plate can be reduced, to avoid crab
It is escaped between metal mesh top and anti-escape top plate.
Crab anti-escape network of the invention is made only with pillar, metal mesh and anti-escape top plate, at low cost, easy for installation, prevents
It is good to escape effect, is very suitable for the use of crab cultivation industry.

Specific embodiment
It is for example related each to a specific embodiment of the invention by the description to embodiment below against attached drawing
The shape of component, construction, the mutual alignment between each section and connection relationship, the effect of each section and working principle etc. are made into one
The detailed description of step.
Embodiment 1:
The present embodiment proposes a kind of crab anti-escape network easy for installation, at low cost.
As shown in Figure 1, 2, the crab anti-escape network of the present embodiment includes pillar 1, metal mesh 2, anti-escape bar 3 and anti-escape top plate 4,
The side of the pillar 1 is equipped with several hooks 5, and the top of pillar 1 is equipped with screw hole, anti-escape top plate 4 using across anti-escape top plate 4 and
The bolt 6 for screwing in the screw hole is installed on the top of pillar 1；The top of anti-escape bar 3 is connect by hook 5 with metal mesh 2.
For convenience of insertion underground, the bottom end of the pillar 1, the bottom end of anti-escape bar 3 are cone cell.
As shown in figure 3, bolt 6 is located at the centre of anti-escape top plate 4, the two sides of the anti-escape top plate 4 are located at metal mesh 2
Two sides, the anti-escape top plate 4 is equipped with the limiting slot 7 that Open Side Down, the top of the metal mesh 2 in the position of corresponding metal mesh 2
End is arranged in limiting slot 7.Metal mesh 2 is located at limit of the part by limiting slot 7 between two pillars 1, will not arbitrarily shake
It is dynamic, improve stability；And by setting limiting slot 7, the spacing between 2 top of metal mesh and anti-escape top plate 4 can be reduced,
To avoid crab from escaping from between 2 top of metal mesh and anti-escape top plate 4.
When building crab anti-escape network, pillar 1 is well placed first, in accordance with scheduled spacing, and metal mesh 2 is placed in
Then pillar 1 is passed down through the mesh of metal mesh 2 and is inserted into soil 8 by the side of pillar 1, so that pillar 1 is vertically solid
Metal mesh 2 is caught on around crab farming pond, and using hook 5, is difficult to anti-escape network under crab and other external forces
It moves up；Finally anti-escape bar 3 is inserted into soil 8, the bottom of metal mesh 2 can be firmly adjacent to ground and fixation, then
Anti-escape top plate 4 is placed on downwards 2 top of pillar 1 and metal mesh, is fixedly connected with anti-escape top plate 4 with pillar 1 using bolt 6, it is complete
At the construction of crab anti-escape network.Crab can not climb over anti-escape top plate 4 upwards and cross anti-escape network, also can not be under metal mesh 2
Side is fled from, to play anti-escape purpose.
The present invention is exemplarily described above in conjunction with attached drawing, it is clear that the present invention specifically designs not by aforesaid way
Limitation, if use the improvement for the various unsubstantialities that conception and technical scheme of the invention carry out, or it is not improved will
