Embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings, to make those skilled in the art with reference to specification text
Word can be implemented according to this.
As shown in Figure 1, Figure 2 and Figure 3, the present invention provides a kind of number statistical method of fish culture in net pen larger fish, including
Following steps：Step 1: providing a net cage 1, slide rail 2, one are respectively formed with the upper edge of two opposing sidewalls of the net cage 1
The top of dictyosome 4 is rotatably arranged with a rotating shaft, and the two ends of the rotating shaft are respectively arranged with pulley 3, and a motor connection is to described
Rotating shaft, the mode that each pulley 3 can be slided along the slide rail is arranged on a slide rail 2, so that the dictyosome is movably disposed
In the net cage；The face of sectional area and the dictyosome of the net cage on the direction vertical with the moving direction of the dictyosome
Product is consistent, and the dictyosome 5 has equally distributed some circular mesh 6, and the diameter of all circular mesh 6 is consistent；For appointing
One mesh 6, each mesh is limited by a tubular structure 8, and the inwall of the tubular structure is provided with rubber layer, in the tubular structure
The circumferential edge of entrance and exit be respectively arranged with 8~10 pressure sensor pasters 7, a counter is connected to the mesh
On all pressure sensor pasters；One processor is connected to the meshed counter of institute；Step 2: the motor is opened, institute
Stating motor drives the side of dictyosome from the net cage to be at the uniform velocity moved to opposite side, wherein, in the moving process of the dictyosome
In, for any one mesh, when the entrance of tubular structure 8 has the pressure sensor paster of 5 or more than 5 while producing pressure
Signal, and also there is the pressure sensor paster of 5 or more than 5 outlet of tubular structure 8 while producing pressure signal, then counts
The number of number device meter 1, and a count signal is sent to the processor, treat that the dictyosome is moved to the opposite side of the net cage,
The number of larger fish in the net cage is used as using the number of the count signal received by the processor.
In the present invention, net cage is separated into two parts by dictyosome, and fish can only be by the mesh of dictyosome from the side of net cage
Move about to opposite side.When a lateral opposite side movement of the dictyosome from net cage, fish can be forced to pass through from tubular structure.For body
The less fish of type, it directly can pass through from tubular structure, without touching any pressure sensor paster, or tubular is encountered in wiping
Structure, but because build is smaller, less than 5 pressure sensor pasters can only be touched, do not counted now.It is larger for build
Fish, its by when and tubular structure contact area it is big, especially entrance and exit can all touch 5 or 5 with
On pressure sensor paster, now just count.But the numeral counted meets certain requirements, you can fished for.Circular
Tubular structure does not have corner angle, prevent fish by when it is injured.
In order to further promote fish by mesh, the water body on front side of dictyosome can be disturbed.Front side refers to relative to net herein
For the moving direction of body.
The girth of mesh is determined according to the bust of fish to be detected, so that fish to be detected can touch when by mesh
5~10 pressure sensor pasters, and then meet monitoring condition.And the length direction of tubular structure is and plane phase where dictyosome
Vertical, its length is then determined according to the body length of fish to be detected, is consistent substantially with body length.Tubular structure inwall is overall
Cover last layer rubber layer, be in order to prevent larger fish by when damage.
The dictyosome of the present invention can be only when needing to detect larger fish, then be placed in net cage, it is to avoid dictyosome
Long period of soaking causes electronic device precise decreasing in water.Pressure sensor paster of the present invention, which is used, to be applied under water
The model of detection, counter and processor are then not arranged on dictyosome, and counter passes through waterproof cable and pressure sensor paster
Connection.
Preferably, in the number statistical method of described fish culture in net pen larger fish, for any one mesh, when being less than
The pressure sensor paster of 5 produces pressure signal, then counter is not counted.
Preferably, in order to meet in the precision that monitoring judges, the number statistical method of described fish culture in net pen larger fish,
For any one mesh, 10 pressure sensor pasters are provided with the circumferential edge of the entrance and exit of the tubular structure.
Preferably, in the number statistical method of described fish culture in net pen larger fish, the translational speed of the net cage is 1m/
min。
In order to improve the precision of monitoring and statisticses, can using the average value of multiple statistic as actual numerical value, specifically,
In the number statistical method of described fish culture in net pen larger fish, in the step 2, with the dictyosome from a sidesway of net cage
Move to opposite side once to move, the motor drives the dictyosome to be moved back and forth n times in the net cage, with n motion institute
In the obtained net cage average value of the number of larger fish as the number of larger fish in the net cage actual numerical value.
Preferably, in the number statistical method of described fish culture in net pen larger fish, n values 6 times.
Preferably, watched for the ease of poultry feeders, in the number statistical method of described fish culture in net pen larger fish, institute
State processor and be additionally coupled to a display, and will be large-scale in the number and the net cage of larger fish in net cage during each motion
The actual numerical value of the number of fish is shown in the display.
Although embodiment of the present invention is disclosed as above, it is not restricted in specification and embodiment listed
With it can be applied to various suitable the field of the invention completely, can be easily for those skilled in the art
Other modification is realized, therefore under the universal limited without departing substantially from claim and equivalency range, the present invention is not limited
In specific details and shown here as the legend with description.
