Description
Technical field
The utility model belongs to aquaculture, physiology of fishes and ecological field of scientific study, relate to a kind of investigate the reservoir stock of fish lift net arrangement.
Background technology
China's size reservoir is numerous, and in reservoir, fishery resources are enriched, and being that movable important waters is fished in fishery, is the revenue source that local fishery is main.Meanwhile, in the research of Fishery Ecology, be the important content often related to the investigation of fishery resources and assessment.
Fish in activity at present to reservoir, the most widely used fishing gear is the passivity fishing gear such as gill net and cage class, these fishing gears use simple to operation, but also there are some defects simultaneously, such as standing time easily causes caught fish kills slightly for a long time, thus can not carry out selectivity to the little individual fish in catches and rare species and free, in addition, Gillnet is fragile, and cost is higher.
Summary of the invention
The technical problems to be solved in the utility model be to provide a kind of investigate the reservoir stock of fish lift net arrangement, after can initiatively fish being caught, optionally fish is studied, fish can not be allowed to stop in fishing net long-time, and the utility model is simple to operate, time saving and energy saving, extra injury can not be carried out to fish tape.
In order to solve the problem, the technical solution of the utility model is: a kind of investigate the reservoir stock of fish lift net arrangement, comprise a square fishing net, four corners of fishing net are respectively equipped with one draw in the net to restrict, draw in the net all to be mounted with a support bar near rope at every root, support bar is provided with top sheave and alignment ring, two support bars of side wherein are also provided with lower sheave, the described rope that draws in the net is positioned at alignment ring
Also take-up pulley is mounted with in the side of support bar, described take-up pulley has the larger large roller of diameter and the less little roller of a diameter, the end face of take-up pulley is also provided with handle, is provided with bracing frame in the below of take-up pulley, described take-up wheel shaft is connected in bracing frame
Drawing in the net rope away from two of described take-up pulley is first draw in the net rope, and the first fag end drawing in the net to restrict is fixedly connected on large roller, and described first draws in the net to restrict is overlapped on the top sheave of support bar,
Drawing in the net rope near two of described take-up pulley is second draw in the net rope, and the second fag end drawing in the net to restrict is fixedly connected on little roller, and described second draws in the net to restrict is overlapped on the lower sheave of support bar,
Support bar is fixedly connected with support, support is provided with bulb.
Adopt the technique effect after this structure to be: rotary wire-reeling wheel carry out receipts net time, due to the roller of take-up pulley two different-diameters, therefore the fishing net away from take-up pulley one end first lifts, the fish in fishing net can be made like this to move to take-up pulley direction, so just very easily fish is concentrated, staff can by concentrate after fish optionally study, when fish select after, fishing net can be put down at once, remaining fish is freeed; Due to what first lifted by side during fishing net, so lift relative to by whole fishing net simultaneously, more laborsaving; In the utility model, the effect of bulb is to fish night, and the utility model can be studied the shoal of fish within the different time; The utility model adopts pulley structure, can regulate the placement depth of water of fishing net so very easily, so just can better estimate biomass and the density of certain fish population.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described further:
Fig. 1 is perspective view of the present utility model,
Fig. 2 is the front view of take-up pulley of the present utility model.
Embodiment
As illustrated in fig. 1 and 2: a kind of investigate the reservoir stock of fish lift net arrangement, comprise a square fishing net 3, four corners of fishing net 3 are respectively equipped with one draw in the net to restrict, draw in the net all to be mounted with a support bar 1 near rope at every root, support bar 1 is provided with top sheave 11 and alignment ring 13, two support bars 1 of side wherein are also provided with lower sheave 12, described in draw in the net rope and be positioned at alignment ring 13
Take-up pulley 6 is also mounted with in the side of support bar 1, described take-up pulley 6 has the larger large roller 61 of diameter and the less little roller 62 of a diameter, the end face of take-up pulley 6 is also provided with handle 63, bracing frame 7 is provided with in the below of take-up pulley 6, described take-up pulley 6 axle is connected in bracing frame 7
Drawing in the net rope away from two of described take-up pulley 6 is first draw in the net rope 2, and the first fag end drawing in the net rope 2 is fixedly connected on large roller 61, and described first draws in the net rope 2 is overlapped on the top sheave 11 of support bar 1,
Drawing in the net rope near two of described take-up pulley 6 is second draw in the net rope 21, and the second fag end drawing in the net rope 21 is fixedly connected on little roller 62, and described second draws in the net rope 21 is overlapped on the lower sheave 12 of support bar 1,
Support bar 1 is fixedly connected with support 4, support 4 is provided with bulb 5.
Using method: need pull-up fishing net 3 constantly, can swing handle 63, under the effect of take-up pulley 6, fishing net 3 away from take-up pulley 6 one end first lifts, and the fish in fishing net 3 slowly draws close to one end, when fishing net 3 surfaces completely, staff just can choose needs the fish of research to study, after fish selects, fishing net 3 can be put down, fish is freeed.
When fishing night, bulb 5 can be opened, the light that bulb 5 sends by insect attractant in fishing net 3, because fish are to the taxis of food organisms, fish can go out assemble to light, lifted by fishing net 3, collect fish wherein according to said method, carry out selecting, classify, count and weighing, the utility model can also according to data such as the biomass of certain fish populations of estimation such as the depth of water of fishing net 3 placement and time and density simultaneously.
